TY - JOUR T1 - The role of niche overlap, environmental heterogeneity, landscape roughness and productivity in shaping species abundance distributions along the Amazon-Andes gradient AN - 1859497483; PQ0004014196 AB - Aim Statistical and ecological mechanisms shape species abundance distributions (SADs). A lack of correlation between ecological gradients and SAD shape would suggest that SADs are caused by purely statistical reasons. We evaluated the variation in the shape of SADs for communities in landscapes of differing variable connectivity, environmental heterogeneity, species niches overlap and productivity. Location Rainforests in the Madidi region (Bolivia). Methods We compiled biological and environmental information on 65 sites (a site being a group of two to six 0.1-ha plots where woody plants of a diameter at breast height greater than or equal to 2.5 cm were inventoried). We built unveiled (complete) SADs for each site and fitted Gambin models to those SADs. The Gambin alpha parameter served as a metric of SAD shape. Low alpha values characterize logseries-like SADs, while high alpha values characterize lognormal-like SADs. For each site, we estimated landscape roughness, environmental heterogeneity, species niche overlap and productivity. These variables were related to SAD shape by means of variation partitioning. Results SADs changed from logseries-like to lognormal-like along the elevational gradient. Many of our predictor variables were correlated: 40.4% of the variation in SAD shape could not be attributed to specific factors. However, 50.62% of the variation in the SAD shape could be assigned to individual predictor matrices: 28.4% was explained exclusively by niche overlap, 15.41% exclusively by environmental heterogeneity, 5.20% exclusively by landscape roughness and 1.6% exclusively by productivity. Main conclusions Ecological processes related to the topographical/environmental complexities that vary across the elevational gradient are correlated with the SAD shape. Purely statistical mechanisms are apparently not sufficient to explain the changes in SAD shape. The most important factor is the mean overlap of the niches of the species of an assemblage: avoiding competition with co-occurring species could be the most important mechanism driving species relative success at the less than or equal to 100 km super(2) scale.

By tracking the functional diversity of the North American large mammal fauna through the End-Pleistocene megafaunal extinction and up to the present, I show that contrary to expectations, functionally unique species are no more likely to go extinct than functionally redundant species. This makes total functional richness loss no worse than expected given similar taxonomic richness declines. However, where current species sit in functional space relative to pre-anthropogenic baselines is not random and likely explains ecosystem functional changes better than total functional richness declines. Prehistoric extinctions have left many extant species functionally isolated and future extinctions will cause even more rapid drops in functional richness.

A promising approach for assessing genetic accommodation involves using a comparative framework to ask whether ancestral plasticity is related to the evolution of a particular trait. Bees are an excellent group for such comparisons because caste-based societies (eusociality) have evolved multiple times independently and extant species exhibit different modes of eusociality. We measured brain and abdominal gene expression in a facultatively eusocial bee, Megalopta genalis, and assessed whether plasticity in this species is functionally linked to eusocial traits in other bee lineages. Caste-biased abdominal genes in M. genalis overlapped significantly with caste-biased genes in obligately eusocial bees. Moreover, caste-biased genes in M. genalis overlapped significantly with genes shown to be rapidly evolving in multiple studies of 10 bee species, particularly for genes in the glycolysis pathway and other genes involved in metabolism. These results provide support for the idea that eusociality can evolve via genetic accommodation, with plasticity in facultatively eusocial species like M. genalis providing a substrate for selection during the evolution of caste in obligately eusocial lineages.

The magnitude of the resulting loss in arthropod biodiversity and associated ecosystem services represents a significant topic of research. In this study we contrasted the abundance, species richness and faunal turnover of butterflies, resident butterflies (i.e., whose host plants were ascertained to occur in the habitats studied) and termites between small (average 4.3 ha) 20+ year old exotic plantations (teak and Terminalia), native plantations (Cedro espino), and an old growth forest in Panama. We used Pollard walks and manual search to quantify the abundance or occurrence of butterflies and termites, respectively. In 2014 we observed 4610 butterflies representing 266 species and 108 termite encounters (out of 160 quadrats) representing 15 species. Butterflies were more abundant and diverse in plantations than in the forest, whereas this pattern was opposite for resident butterflies and termites. There was marked faunal turnover between plantations and forest. We conclude that (a) the magnitude of faunal changes between forest and plantations is less drastic for termites than for butterflies; (b) resident butterfly species are more impacted by the conversion of forest to plantations than all butterflies, including transient species; and (c) species richness does not necessarily decrease in the series forest > native > exotic plantations. Whereas there are advantages of studying more tractable taxa such as butterflies, the responses of such taxa can be highly unrepresentative of other invertebrate groups responsible for different ecological services.

Sauropod remains are very rare at all these localities and represented usually only by isolated teeth. Only narrow-crowned teeth are known from the Cretaceous of Central Asia. The oldest record of such teeth is from the Aptian Sultanbobo Formation of Uzbekistan. Exposures of the Turonian Bissekty Formation at the most productive vertebrate locality in the region, Dzharakuduk in Uzbekistan, has yielded many isolated teeth and a few skeletal remains that can be attributed to a non-lithostrotian titanosaur. Similar narrow-crowned, cylindrical teeth from Cenomanian-to Coniacian-age strata in the Kyzylkum Desert, Uzbekistan, may belong to a closely related taxon. Another taxon, with teeth that are pentagonal in cross-section, is known from the Santonian Yalovach and Bostobe formations of Tajikistan and western Kazakhstan, respectively. A femur reported from the Santonian Syuksyuk Formation of southern Kazakhstan possibly belongs to a lithostrotian titanosaur. The change in tooth structure at the Coniacian-Santonian boundary in the region possibly suggests replacement of non-lithostrotian titanosaurs by lithostrotians. The titanosaur from the Bissekty Formation is similar to Dongyangosaurus sinensis from the Cenomanian-Turonian of Zhejiang (China) in the extensive pneumatization of the neural arch on the anterior caudal vertebrae with several fossae. It also resembles Baotianmansaurus henanensis from the Cenomanian of Henan (China) in the possession of very short anterior caudal centra. These three taxa possibly represent an as yet formally unrecognized endemic clade of Asian non-lithostrotian titanosaurs.

On the basis of neutron transport simulations and remotely sensed elemental compositions, cosmic-ray-induced fast neutrons are shown to provide a measure of average atomic mass, , a result consistent with earlier studies of the Moon and Vesta. The dynamic range of fast neutron flux at Mercury is 3%, which is smaller than the fast-neutron dynamic ranges of 30% and 6% at the Moon and Vesta, respectively. Fast-neutron data delineate compositional terranes on Mercury that are complementary to those identified with X-ray, gamma-ray, and slow-neutron data. Fast neutron measurements confirm the presence of a region with high , relative to the mean for the planet, that coincides with the previously identified high-Mg region and reveal the existence of at least two additional compositional terranes: a low- region within the northern smooth plains and a high- region near the equator centered near 90 degrees E longitude. Comparison of the fast-neutron map with elemental composition maps show that variations predicted from the combined element maps are not consistent with the measured variations in fast-neutron flux. This lack of consistency could be due to incomplete coverage for some elements or uncertainties in the interpretations of compositional and neutron data. Currently available data and analyses do not provide sufficient constraints to resolve these differences.

Among these is the Shallow Radar (SHARAD) instrument, supplied by Agenzia Spaziale Italiana (ASI) and designed for subsurface sounding in the 15-25 MHz frequency band. As of this writing, MRO has completed more than 46,000 nearly polar orbits of Mars, 30% of which have included active SHARAD data collection. By 2009, a sufficient density of SHARAD coverage had been obtained over the polar regions to support 3D processing and analysis of the data. Using tools and techniques commonly employed in terrestrial seismic data processing, we have processed subsets of the resulting collection of SHARAD observations covering the north and south polar regions as SHARAD 3D volumes, imaging the interiors of the north and south polar ice caps known, respectively, as Planum Boreum and Planum Australe. After overcoming a series of challenges revealed during the 3D processing and analysis, a completed Planum Boreum 3D volume is being used currently for scientific research.

Eustasy has generally been considered as a consequence of the growth and decay of continental ice sheets that would explain large, rapid changes in sea level, even during periods of relative global climatic warmth. However, such a mechanism has become increasingly difficult to envision during times of extreme global warmth such as the Turonian, when the equator-to-pole temperature gradient was very low and the presence of polar ice seems improbable. This paper investigates the timing and extent of sea level falls during the late Cenomanian through Turonian, especially the largest of those events, sequence boundary KTu4, which occurred during the middle to late Turonian peak of the Cretaceous hot greenhouse climate. We conclude that the amplitude of the widespread third-order sea level fall in the middle Turonian that is centered at ~91.8 Ma varies at different locations depending on the influence of dynamic topography on local tectonics and regional climatic conditions. Ice volume variations seem unlikely as a mechanism for controlling sea level at this time. However, this causal factor cannot be ruled out completely since Antarctic highlands (if they existed in the Late Cretaceous) could sequester enough water as ice to cause eustatic falls. To ascertain this requires detailed tomographic imaging of Antarctica, followed by geodynamic modeling, to determine whether high plateaus could have existed to accumulate ephemeral ice sheets. Other mechanisms for sea level change, such as transference between ground water (a small amplitude shorter time scale effect) and the ocean and entrainment and release of water from the mantle to the oceanic reservoir (a potentially large amplitude and longer time scale process), are intriguing and need to be explored further to prove their efficacy at third-order time scales.

Identification of the mechanisms enabling stable coexistence of species with similar resource requirements is a central challenge in ecology. Such coexistence can be facilitated by species at higher trophic levels through complex multi-trophic interactions, a mechanism that could be compromised by ongoing defaunation. 2. We investigated cascading effects of defaunation on Pachymerus cardo and Speciomerus giganteus, the specialized insect seed predators of the Neotropical palm Attalea butyracea, testing the hypothesis that vertebrate frugivores and granivores facilitate their coexistence. 3. Laboratory experiments showed that the two seed parasitoid species differed strongly in their reproductive ecology. Pachymerus produced many small eggs that it deposited exclusively on the fruit exocarp (exterior). Speciomerus produced few large eggs that it deposited exclusively on the endocarp, which is normally exposed only after a vertebrate handles the fruit. When eggs of the two species were deposited on the same fruit, Pachymerus triumphed only when it had a long head start, and the loser always succumbed to intraguild predation. 4. We collected field data on the fates of 6569 Attalea seeds across sites in central Panama with contrasting degrees of defaunation and wide variation in the abundance of vertebrate frugivores and granivores. Speciomerus dominated where vertebrate communities were intact, whereas Pachymerus dominated in defaunated sites. Variation in the relative abundance of Speciomerus across all 84 sampling sites was strongly positively related to the proportion of seeds attacked by rodents, an indicator of local vertebrate abundance. 5. Synthesis. We show that two species of insect seed predators relying on the same host plant species are niche differentiated in their reproductive strategies such that one species has the advantage when fruits are handled promptly by vertebrates and the other when they are not. Defaunation disrupts this mediating influence of vertebrates and strongly favours one species at the expense of the other, providing a case study of the cascading effects of defaunation and its potential to disrupt coexistence of non-target species, including the hyperdiverse phytophagous insects of tropical forests. The unprecedented rates of defaunation, that is the loss of medium and large animals from ecosystems, are among the main features distinguishing the Anthropocene. With the fading of their populations, all their trophic interactions are also vanishing with unanticipated effects on the coexistence of other non-target species.

A more comprehensive assessment is important for understanding the contribution of phytoplankton production to the global carbon budget, present and future. Here, we consider responses in the temperate and tropical mid-ocean regions typically dominated by picophytoplankton including the prokaryotic lineages, Prochlorococcus and Synechococcus. Spectral models of photosynthetic response for each lineage were constructed using model strains cultured at different growth irradiances and temperatures. In the model, inhibition becomes more severe once exposure exceeds a threshold (E sub(max)) related to repair capacity. Model parameters are presented for Prochlorococcus adding to those previously presented for Synechococcus. The models were applied to estimate midday, water column photosynthesis based on an atmospheric model of spectral radiation, satellite-derived spectral water transparency and temperature. Based on a global survey of inhibitory exposure severity, a full-latitude section of the mid-Pacific and near-equatorial region of the east Pacific were identified as representative regions for prediction of responses over the entire water column. Comparing predictions integrated over the water column including versus excluding inhibition, production was 7-28% lower due to inhibition depending on strain and site conditions. Inhibition was consistently greater for Prochlorococcus compared to two strains of Synechococcus. Considering only the surface mixed layer, production was inhibited 7-73%. On average, including inhibition lowered estimates of midday productivity around 20% for the modeled region of the Pacific with UV accounting for two-thirds of the reduction. In contrast, most other productivity models either ignore inhibition or only include PAR inhibition. Incorporation of E sub(max) model responses into an existing spectral model of depth-integrated, daily production will enable efficient global predictions of picophytoplankton productivity including inhibition.

AN - 1859480975; PQ0003994196 AB - Climate change is predicted to increase the frequency and severity of extreme events. However, the biological consequences of extremes remain poorly resolved owing to their unpredictable nature and difficulty in quantifying their mechanisms and impacts. One key feature delivering precipitation extremes is an atmospheric river (AR), a long and narrow filament of enhanced water vapour transport. Despite recent attention, the biological impacts of ARs remain undocumented. Here, we use biological data coupled with remotely sensed and in situ environmental data to describe the role of ARs in the near 100% mass mortality of wild oysters in northern San Francisco Bay. In March 2011, a series of ARs made landfall within California, contributing an estimated 69.3% of the precipitation within the watershed and driving an extreme freshwater discharge into San Francisco Bay. This discharge caused sustained low salinities (less than 6.3) that almost perfectly matched the known oyster critical salinity tolerance and was coincident with a mass mortality of one of the most abundant populations throughout this species' range. This is a concern, because wild oysters remain a fraction of their historical abundance and have yet to recover. This study highlights a novel mechanism by which precipitation extremes may affect natural systems and the persistence of sensitive species in the face of environmental change.

The unusually high quality of preservation is commonly attributed to shallow burial and high clay content of the host sediments. However, such attributes apply to many deposits that are not characterized by exceptional preservation, and, thus, invoking only grain size and burial depth is clearly an incomplete explanation for the exceptional microfossil preservation. In an attempt to better characterize additional factors that were important in creating the Tanzanian microfossil lagerstatte, we integrated a wide range of paleontological, geochemical, and sedimentological observations to constrain the paleoenvironmental and early diagenetic conditions of a Turonian interval where exceptional preservation is common. Planktic microfossil assemblages suggest that open-ocean surface-water conditions prevailed at the site, but, despite excellent organic matter preservation, marine biomarkers are rare. The sediments are dominantly composed of terrigenous silts and clays and terrestrially derived organic matter. Paleontological and geochemical observations record a remarkably stable interval dominated by excellent preservation through the Lower-Middle Turonian. During the Middle-Upper Turonian, though, the preservation quality declines, and this is associated with notable shifts in foraminiferal assemblages, palynological species diversity, carbon and sulfur isotope compositions, and biomarker distributions. The integrated data suggest that an increase in subsurface microbial activity and associated changes in pore-water chemistry were important proximate variables that led to the decline in the quality of microfossil preservation up section within these shallowly buried, Turonian silty claystones from Tanzania.

We provide new geologic and U-Pb zircon geochronologic constraints on the Neoproterozoic and early Paleozoic tectonic evolution of the terrane. Orthogneisses dated as ca. 1967 and ca. 839 Ma form the basement and are intruded and overlain by ca. 811-787 Ma arc-volcanic and volcaniclastic rocks that lack a gneissic fabric, suggestive of a mid-Neoproterozoic metamorphic event. Rifting and formation of the Zavkhan ribbon continent occurred from ca. 770-717 Ma and was followed by passive margin sedimentation between 717 and 580 Ma. During the latest Ediacaran to Cambrian, the southern margin of the Zavkhan terrane was reactivated with the obduction of the Lake terrane, slab break-off and reversal, and ca. 509-507 Ma magmatism. Metamorphosed Proterozoic and Cambrian units are cut by undeformed ca. 496 Ma gabbro, providing a tight constraint on the age of Cambrian metamorphism. Late Ordovician to Silurian rifting is marked by bimodal magmatism and deposition in narrow fault-bound basins. Our data indicate that the Zavkhan terrane traveled alone in the Neoproterozoic, collided with the Lake terrane in the late Ediacaran to Cambrian, accreted an unknown crustal block during Cambrian Epoch 2-Epoch 3, and then rifted away in the Ordovician. We suggest the majority of continental growth in Mongolia occurred through the trapping and oroclinal bending of ribbon continents rather than long-lived accretion on the margin of a major craton.

The objectives of the study were to (1) optimize the concentration and duration of carbonyl cyanide 4-(trifluoromethoxy)phenylhydrazone (FCCP-a mitochondrial uncoupling agent) exposures for biopsies of domestic cat ovarian tissue and (2) examine the effects of FCCP pre-exposures on follicle integrity after tissue culture and/or cryopreservation. Biopsies of cat ovarian tissue were first treated with various concentrations of FCCP (0, 10, 40, or 200 nM) for 10 or 120 min to determine the most suitable pre-exposure conditions. Based on these results, tissues were pre-exposed to 200 nM FCCP for 120 min for the subsequent studies on culture and cryopreservation. In all experiments and for each treatment group, tissue activity and integrity were measured by mitochondrial membrane potential (relative optical density of rhodamine 123 fluorescence), follicular viability (calcein assay), follicular morphology (histology), granulosa cell proliferation (Ki-67 immunostaining), and follicular density. Ovarian tissues incubated with 200 nM FCCP for 120 min led to the lowest mitochondrial activity (1.17 plus or minus 0.09; P0.05). After 2 days of in vitro culture, percentage of viable follicles (78.8 plus or minus 8.9 %) in similar pre-exposure conditions was higher (P0.05). Interestingly, percentages of cellular proliferation and follicular density were unaltered by the FCCP exposures. Based on the indicators mentioned above, the FCCP-treated tissue fragments did not have a better follicle integrity after freezing and thawing. Pre-exposure to 200 nM FCCP during 120 min protects and enhances the follicle integrity in cat ovarian tissue during short-term in vitro culture. However, FCCP does not appear to exert a beneficial or detrimental effect during ovarian tissue cryopreservation.

The ranking of a species on the slow-fast continuum - the covariation among life-history traits describing species-specific life cycles along a gradient going from a long life, slow maturity, and low annual reproductive output, to a short life, fast maturity, and high annual reproductive output - strongly correlates with the relative fitness impact of a given amount of variation in adult survival. Under the canalization hypothesis, long-lived species are thus expected to display less individual heterogeneity in survival at the onset of adulthood, when reproductive values peak, than short-lived species. We tested this life-history prediction by analysing long-term time series of individual-based data in nine species of birds and mammals using capture-recapture models. We found that individual heterogeneity in survival was higher in species with short-generation time ( 4 years). Our findings provide the first piece of empirical evidence for the canalization hypothesis at the individual level from the wild.

There is growing concern that once initiated, these nonforested landscapes could be perpetuated almost indefinitely through a suite of positive feedbacks with fire. The rapid deforestation of much of New Zealand following human settlement (ca. 750 years ago) provides a rare opportunity to evaluate the feedback mechanisms that facilitated such extensive transformation and thereby help us to identify factors that confer vulnerability or resilience to similar changes in other regions. Here we evaluate the structure of living and dead vegetation (fuel loading) and microclimate (fuel moisture) in beech (Nothofagaceae) forests and adjacent stands that burned within the last 60-140 years and are dominated by mAenuka (Leptospermum scoparium) or kAenuka (Kunzea spp.). We show that the burning of beech forests initiates a positive feedback cycle whereby the loss of microclimatic amelioration under the dense forest canopy and the abundant fine fuels that dry readily beneath the sparse mAenuka/kAenuka canopy enables perpetuation of these stands by facilitating repeated burning. Beech regeneration was limited to a narrow zone along the margin of unburned stands. The high flammability of vegetation that develops after fire and the long time to forest recovery were the primary factors that facilitated extensive deforestation with the introduction of human-ignited fire. Evaluating these two characteristics may be key to determining which regions may be near a tipping point where relatively small land-use- or climatically driven changes to fire regimes could bring about extensive deforestation.

However, eutrophication and sedimentation have decimated the Bay's SAV population to a fraction of its historical coverage. Understanding the spatial distribution of and connectedness among patches is important for assessing the dynamics and health of the remaining SAV population. We seek to explore the distribution of SAV patches and patterns of potential connectivity in the Chesapeake Bay through time. We assess critical distances, from complete patch isolation to connection of all patches, in a merged composite coverage map that represents the sum of all probable Vallisneria americana containing patches between 1984 and 2010 and in coverage maps for individual years within that timeframe for which complete survey data are available. We have three key findings: First, the amount of SAV coverage in any given year is much smaller than the total recently occupied acreage. Second, the vast majority of patches of SAV that are within the tolerances of V. americana are ephemeral, being observed in only 1 or 2 years out of 26 years. Third, this high patch turnover results in highly variable connectivity from year to year, dependent on dispersal distance and patch arrangement. Most of the connectivity thresholds are beyond reasonable dispersal distances for V. americana. If the high turnover in habitat occupancy is due to marginal water quality, relatively small improvements could greatly increase V. americana growth and persistence.

Our aim was to characterize Addra ejaculate traits and to assess the effects of cholesterol-loaded cyclodextrin (CLC) on sperm cryosurvival. Fresh ejaculates were treated with CLC (0, 0.5, 1.5, 3.0, and 6.0 mg/ml) prior to cryopreservation. All males produced spermic ejaculates with >75% sperm motility. The mean plus or minus SEM seminal volume, sperm concentration, percent motility, forward progression, and percent morphologically normal spermatozoa were 3.2 plus or minus 0.3 ml, 1.2 plus or minus 0.3 109, 75.82 plus or minus 2.7%, 3.2 plus or minus 0.3 (0-5 scale; 5 = most progressive), and 57.12 plus or minus 3.8%, respectively. More than 92% contained an intact acrosome. There was no effect of time or in vitro incubation on progression or acrosomal integrity on thawed samples (P > 0.05). Spermatozoa pre-treated with 0.5 mg/ml CLC retained higher (P 0.05). Linearity (LIN) and straightness (STR) were different among samples after thawing. Results demonstrate treatment with CLC (0.5 mg/ml) protects Addra spermatozoa from cryo-damage. Reported advances will facilitate establishment of a frozen repository and support the genetic management of this critically endangered north African desert antelope.

AN - 1835511672; 27568458 AB - The objectives of the present study were to evaluate sperm characteristic of captive clouded leopards in Thailand and examine the structural and functional properties of sperm after selection with the single-layer centrifugation (SLC) method. Twenty-two ejaculates from 11 captive clouded leopards (four housed with access to a female in estrus, and seven housed singly) were collected and assessed for semen traits during 2013 to 2015. Twelve fresh ejaculates were chosen from seven males, and each was divided between two sperm preparation methods; (1) simple washing and (2) SLC. Cryopreservation was performed after semen preparation. Sperm qualities after selections including motility, progressive motility, sperm motility index, viability, acrosome integrity, DNA integrity, and morphology were evaluated in fresh, chilled, and frozen-thawed samples. In addition, sperm functionality after cryopreservation was tested by heterologous IVF using domestic cat oocytes. Sperm motility in the ejaculates was 52.5% to 91.3% (76.8 ± 2.0%, mean ± standard error). A high proportion of morphologically abnormal sperm (63.9 ± 2.0%) was observed, with the major abnormality being tightly coiled tail (13.5 ± 0.5%). An interesting observation was that males housed together with a female had a significantly higher proportion of sperm with intact acrosome (47.9 ± 3.4% and 38.4 ± 2.8%) and lower proportion of sperm with bent midpiece and droplet (7.1 ± 0.6% and 10.2 ± 0.5%) than the males living singly. The sperm motility index, intact acrosome, and sperm with normal tail in the fresh and chilled semen samples were improved by the SLC. In the postthawed semen, the SLC selected higher numbers of viable sperm (34.1 ± 2.2% and 27.9 ± 1.8%), sperm with intact acrosome (31.2 ± 2.1% and 24.3 ± 2.2%), and sperm with normal tail (34.2 ± 2.7% and 24.3 ± 2.7%) than simple washing. Also, the proportion of sperm with tightly coiled tail was lower in the SLC-processed than the simple washed samples (8.1 ± 3.1% and 13.5 ± 3.4%). The SLC-processed group had significantly higher penetration rate in heterologous IVF (29.4 ± 3.0%) than the simple washing group (15.8 ± 3.2%). In conclusion, ejaculates of clouded leopards living in Thailand demonstrated teratospermic characteristic similar to the previous reports from other continents. Single-layer centrifugation is a promising tool to select morphologically normal sperm of teratospermic donors. The successes of assisted reproductive technology could be enhanced by the improved quality of postthaw sperm in this species. Copyright © 2016 Elsevier Inc. All rights reserved.

The degradation state of the crater has been studied using orbital data from the Mars Reconnaissance Orbiter and in situ data from the Opportunity rover. Multiple exposed crater rim segments range in elevation from approximately 10 m to over 100 m above the level of the embaying Burns Formation. The crater is 200-500 m deep and the interior wall exposes over approximately 300 m of relief around the southern half of the crater. Slopes of 6-16% flank the exterior of the largest western rim segment. On the west side of the crater, both pre-impact rocks (Matijevic Formation) and Endeavour impact ejecta (Shoemaker Formation) are present at Cape York, but only the Shoemaker Formation (up to approximately 140 m section) outcrops at Cape Tribulation. Study of similar sized pristine craters Bopolu and Tooting (with complex morphology) and use of metrics for describing the morphometry of martian craters suggest the original rim of Endeavour averaged 410 m in elevation, but relief varied about + or -200 m around the circumference. A 250-275 m section of ejecta (+ or -50-60 m) would have comprised a significant fraction of the rim height. The original crater was likely 1.5-2.2 km deep and may have had a central peak (no obvious evidence is present) between 200 and 500 m high. Comparison between the predicted original and current form of Endeavour suggests 100-200 m of rim degradation ranging from nearly complete ejecta removal in some locations to preservation of a thick ejecta section in others. Differences in rim relief are at least partially due to degradation and not just original rim relief and (or) due to offsets along rim faults. Most degradation occurred prior to deposition of the Burns Formation which is approximately 200 m thick outside the crater, but likely thicker inside the crater. Aeolian stripping of the Burns Formation continues today via prevailing winds and lesser mass wasting is important on steeper walls. However, analogy with degraded Noachian craters south of Meridiani suggests fluvial processes were most important in early degradation and is consistent with the nearly complete removal of ejecta from some rim segments, gaps in the rim, formation of Marathon Valley, and interpretation of a pediment flanking the western rim. Slope processes likely accompanied incision that may have accounted for tens of metres rim lowering near Marathon Valley to more than 100 m at Cape York.

From a genetic perspective, hybrid ferns are especially interesting because they represent the union of divergent parental genomes in unique evolutionary entities. This review summarizes advances in our knowledge of the genetic and genomic aspects of hybridization in ferns from the mid-20th century to the present. The different organismal products of hybridization, evolutionary aspects of additive and non-additive gene expression in allopolyploids, genetic and genomic mechanisms leading to gene silencing and loss, the roles of multiple origins and introgression for imparting genetic variation to hybrid fern taxa and their progenitors, and the utility of allopolyploid ferns to investigate mechanisms of genome evolution in the homosporous ferns are discussed. Comparisons are made to other plant lineages and important future research directions are highlighted, with the goal of stimulating additional research on hybrid ferns.

Salmon themselves provide food resources to higher trophic levels and deposit rich marine-derived nutrients (MDN) that benefit the base of freshwater food webs. We studied a higher-order terrestrial consumer of aquatic prey, the American dipper Cinclus mexicanus, in a riparian food web, to test the hypothesis that barriers to salmon migration negatively impact body condition, and ultimately life history. We predicted that, compared to dippers breeding above barriers, those in areas with salmon would receive MDN and thus be in better condition, have greater breeding effort (frequency of multiple brood attempts), produce larger offspring in better condition, be more likely to maintain year-round territories, and have higher annual survival. Using stable isotopes as signatures of MDN, we found that super(13)C and super(15)N were more enriched in dippers below barriers, confirming access to MDN. Female dippers below barriers had greater mass corrected for body size, were more likely to attempt multiple broods within a season and produced larger female offspring. Furthermore, dippers below barriers were more likely to maintain year-round territories and had higher annual survival.

Previous studies using molecular markers identified two variants of this species. Our new study, using pollen grain morphology, revealed differences in pollen sculpture between the two variants; that is, in Variant A the exine is characterised as perforate-verrucose, while in Variant B, it is punctuate. Pollen size in Variant A is larger than in Variant B, whereas the exine is thicker in Variant B than in Variant A. The differences in pollen morphology between the two variants represent new evidence suggesting that a diversification process might be occurring within P. rhizophorae, possibly due to adaptive processes in response to environmental conditions or pollination vectors.

AN - 1816630695; 27495827 AB - Several taxonomic and phylogenetic studies have hypothesized polyphyly within Pueraria DC., a genus comprising 19 species (24 with varieties) including the highly invasive Pueraria montana var. lobata (Kudzu) introduced to the U.S.A. about 150years ago. Previous efforts to investigate monophyly of the genus have been hampered by limited taxon sampling or a lack of comprehensive evolutionary context that would enable definitive taxonomic associations. This work presents a comprehensive phylogenetic investigation of Pueraria within the context of tribe Phaseoleae (Leguminosae). Polyphyly was found to be more extensive than previously thought, with five distinct lineages spread across the tribe and spanning over 25mya of divergence strongly supported by two chloroplast and one nuclear marker, AS2, presented here as a phylogenetic marker for the first time. Our phylogenies support taxonomic revisions to rectify polyphyly within Pueraria, including the resurrection of Neustanthus, moving one species to Teyleria, and the creation of two new genera, Haymondia and Toxicopueraria (taxonomic revisions published elsewhere).

However, evidence for an overlapping ecological association between metazoans and soft-bodied Ediacaran organisms is limited. Here, we describe new fossil localities from southern Namibia that preserve soft-bodied Ediacara biota, enigmatic tubular organisms thought to represent metazoans, and vertically-oriented metazoan trace fossils. Although the precise identity of the tracemakers remains elusive, the structures bear several striking similarities with the Cambrian-Recent ichnogenus Conichnus. These new data support inference of stratigraphic and ecological overlap between two very different eukaryotic clades, and indicate the existence of unusual ecosystems comprising both Ediacara biota and metazoans immediately prior to the Cambrian explosion.

While threats to marine and terrestrial ecosystems have fueled increased interest in biodiversity research, information on meiofauna, a key trophic and ecologic community of microscopic organisms that lives within sediments, is still lacking. Here we report the results of a faunistic investigation conducted in Bali, Indonesia. The results reveal that the biodiversity of marine meiofauna in Bali is very high. Meiofauna from coral reefs, sand flats and seagrass beds differed significantly in abundance and diversity. Nonetheless, overall community compositions show that meiofauna communities are affected by environmental variables. The high meiofaunal diversity observed in Bali, a low diversity region of the Coral Triangle, indicates the importance of further meiofaunal research across this region and across a broader diversity of habitats. The data presented provide an important baseline for future studies on biodiversity conservation in the face of environmental changes due to anthropogenic impacts and/or natural events.

Comment on: "Distribution of the dentary groove of theropod dinosaurs: Implications for theropod phylogeny and the validity of the genus Nanotyrannus Bakker et al., 1988" AN - 1832603568; 778799-19 AB - There has been considerable debate about whether the controversial tyrannosauroid dinosaur 'Nanotyrannus lancensis' from the uppermost Cretaceous of North America is a valid taxon or a juvenile of the contemporaneous Tyrannosaurus rex. In a recent Cretaceous Research article, Schmerge and Rothschild (2016) brought a new piece of evidence to this discussion: the morphology of the dentary groove, a depression on the lateral surface of the dentary that houses neurovascular foramina. They argued that an alleged 'Nanotyrannus' specimen, which possesses a groove, cannot be referable to Tyrannosaurus rex, which they considered as lacking the groove, and they hypothesized that 'Nanotyrannus' is closely related to albertosaurine tyrannosauroids, which also are said to possess the groove. However, we show that the groove is a widespread feature of tyrannosauroids that is present in T. rex and many other specimens, and that it is an ontogenetically variable feature that changes from a sharp, deeply-impressed groove to a shallower sulcus as an individual matures. As a result, the presence or absence of a dentary groove does not clarify the validity of 'Nanotyrannus' or its phylogenetic position among tyrannosauroids. We consider it most parsimonious that 'Nanotyrannus' specimens belong to juvenile T. rex.

Despite their common interest in documenting the progress of digitization and online access, the library, archives, and museums (LAM) sector lacks a conceptual framework for assessing and demonstrating the impact of digitized ethnographic collections. Reporting the findings of a yearlong interdisciplinary study, this article underscores the importance of storytelling in articulating the value and impact of digitized ethnographic collections held in cultural heritage institutions. We begin with an overview of the literature on the assessment and describe the methods we employed in our study. Next, we identify and discuss the different ways that stories and storytelling are strategically mobilized in conversations about the impact of digitization. We conclude with a discussion of the implications of our findings for cultural heritage practice and collection development.

When they are abandoned, rice paddy fields generally transform into wetlands by natural succession. While previous studies have mainly focused on vegetation shifts in abandoned rice paddies, little information is available about how these changes may affect their contribution to wetland functions. As newly abandoned fields proceed through succession, their hydrology and plant communities often change. Moreover, the relationships between these changes, soil microbial characteristics, and emissions of greenhouse gasses are poorly understood. In this study, we examined changes over the course of secondary succession of abandoned rice paddies to wetlands and investigated their ecological functions through changes in greenhouse gas fluxes and microbial characteristics. We collected gas and soil samples in summer and winter from areas dominated by Cyperaceae, Phragmites, and Sphagnum in each site. We found that CO sub(2) emissions in summer were significantly higher than those in winter, but CH sub(4) and N sub(2)O emission fluxes were consistently at very low levels and were similar among seasons and locations, due to their low nutrient conditions. These results suggest that microbial activity and abundance increased in summer. Greenhouse gas flux, soil properties, and microbial abundance were not affected by plant species, although the microbial community composition was changed by plant species. This information adds to our basic understanding of the contribution of wetlands that are transformed from abandoned rice paddy systems.

Semen was collected from four mature males during breeding season (March and April) and evaluated for volume, sperm concentration, motility, and membrane integrity. In Experiment 1, ejaculates (n = 8) were diluted with Beltsville Poultry Semen Extender (BPSE) containing 10% dimethylsulfoxide (Me2SO) and frozen using either one (average cooling rate = 2.5 degree C/min) or two step (average cooling rate = 7 and 9 degree C/min, respectively) cooling method. The frozen samples were thawed using one of two thawing rates: 37 degree C 30 s vs. 4 degree C 1 min. In Experiment 2, samples were diluted with crane semen extender containing either 6% or 10% Me2SO, frozen using two-step method and then thawed at 37 degree C for 30 s. Both cooling condition (two-step > one-step) and thawing rate (37 degree C 30 s > 4 degree C 1 min) impacted sperm motility, progression and kinetic characteristics (P 0.05) affect plasma membrane or acrosomal integrity. Concentration of Me2SO did not impact frozen-thaw survival. We conclude that white-naped crane sperm cryopreserved using a combination of two-step cooling and thawing at 37 degree C 30 s was superior to other cooling and thawing combinations regarding to sustaining sperm motility with good motility kinetics. Findings represent the first steps towards the development of effective cryopreservation protocols and establishment of a genome resource bank for this threatened species.

Ovarian cortical pieces from peri-pubertal individuals were exposed to cryoprotectants at 4 degree C or room temperature and supplemented with 0 or 0.5 M of sucrose, followed by vitrification. After rapid warming, cortical pieces were cultured in vitro and assessed for normal follicular morphology, viability and resumption of transcriptional activities for up to 7 days. Throughout the culture period, follicular morphology (up to 67.5% normal follicles) and global RNA transcription (up to 50.9% follicles with transcriptional activity) in warmed tissues were improved by cryoprotectant exposure at 4 degree C compared to room temperature, but viability (up to 84.6% viable follicles) did not seem to be affected by exposure temperature. Sucrose supplementation did not have a consistent effect as it increased RNA transcription but decreased normal follicular morphology. For the first time, the study demonstrated that the preservation of critical tissue functions, such as the transcriptional activities, highly depends on the temperature of the cryoprotectant exposure and not necessarily on the presence of sucrose.

Here, we determined the expression pattern of six MMPs (MMP1, MMP2, MMP3, MMP7, MMP9 and MMP13) and their endogenous tissue inhibitor, TIMP1, during cat follicle growth. Different developmental stage follicles were mechanically isolated and gene expression analysed by real-time qPCR while MMP1, 2, 9 and 13 localization was determined by immunohistochemistry. With the exception of MMP13, the amount of MMP mRNA was lowest in primordial follicles and increased thereafter. Peak levels were detected in early antral follicles for MMP1 (72.2-fold increase above primordial follicle amount), MMP2 (10-fold), MMP3 (57-fold) and MMP9 (2.8-fold). MMP7 transcripts increased 2-fold by the primary follicle stage and then plateaued. MMP13 mRNA peaked in primary follicles (2.5-fold) and was lower in more advanced counterparts. TIMP1 sharply increased (6-fold) in secondary follicles and gradually declined in the later stages. MMP1 and MMP9 expression were expressed in the granulosa cells of all follicle stages. MMP2 was immunoreactive in early and antral follicles, especially at granulosa cells adjacent to the antral cavity. By contrast, the MMP13 was weakly detected in primary follicles onward. In summary, there are distinctive and consistent changes in MMPs and TIMP1 expression during follicle development, suggesting that these enzymes play one or more roles in cat folliculogenesis. In particular, high mRNA and protein expression levels of MMP1 and MMP2, especially at the antral stage, indicate that these enzymes likely are involved in antrum formation and expansion.

In Panama, data on tree communities and underlying soils indicate that species frequently show distributional associations to soil phosphorus. To understand how these associations arise, we combined a pot experiment to measure seedling responses of 15 pioneer species to phosphorus addition with an analysis of the phylogenetic structure of phosphorus associations of the entire tree community. * Growth responses of pioneers to phosphorus addition revealed a clear tradeoff: species from high-phosphorus sites grew fastest in the phosphorus-addition treatment, while species from low-phosphorus sites grew fastest in the low-phosphorus treatment. Traits associated with growth performance remain unclear: biomass allocation, phosphatase activity and phosphorus-use efficiency did not correlate with phosphorus associations; however, phosphatase activity was most strongly down-regulated in response to phosphorus addition in species from high-phosphorus sites. * Phylogenetic analysis indicated that pioneers occur more frequently in clades where phosphorus associations are overdispersed as compared with the overall tree community, suggesting that selection on phosphorus acquisition and use may be strongest for pioneer species with high phosphorus demand. * Our results show that phosphorus-dependent growth rates provide an additional explanation for the regional distribution of tree species in Panama, and possibly elsewhere.

Based on the cumulate textures of the samples and a lack of evidence for Mg-suite extrusives in both the sample and remote sensing databases, several petrogenetic models deduce a predominantly intrusive magmatic history for Mg-suite lithologies. Considering that approximately 18% of the lunar surface is covered by mare basalt flows, which are substantially higher in density than estimated Mg-suite magmas ( approximately 2900 versus approximately 2700 kg/m (super 3) ), the apparent absence of low-density Mg-suite volcanics is surprising. Were Mg-suite magmas predominantly intrusive, or have their extrusive equivalents been covered by subsequent impact ejecta and/or later stage volcanism? If Mg-suite magmas were predominantly intrusive, what prevented these melts from erupting? Or, if they are present as extrusives, what regions of the Moon are most likely to contain Mg-suite volcanic deposits? This study investigates buoyancy-driven ascent of Mg-suite parental melts and is motivated by recent measurements of crustal density from GRAIL. Mg-suite dunite, troctolite, and spinel anorthosite parental melts (2742, 2699, and 2648 kg/m (super 3) , respectively) are considered, all of which have much lower melt densities relative to mare basalts and picritic glasses. Mg-suite parental melts are more dense than most of the crust and would not be expected to buoyantly erupt. However, about 10% of the lunar crust is greater in density than Mg-suite melts. These areas are primarily within the nearside southern highlands and South Pole-Aitken (SP-A) basin. Mg-suite extrusions and/or shallow intrusions were possible within these regions, assuming crustal density structure at >4.1 Ga was similar to the present day crust. We review evidence for Mg-suite activity within both the southern highlands and SP-A and discuss the implications concerning crustal evolution as well as Mg-suite petrogenesis. Lower crustal densities measured by GRAIL are consistent with the lack of observed Mg-suite extrusives. If Mg-suite extrusive volcanism was prevented by the low density of the crust, it would suggest the lunar crust was fractured shortly after solidification (>4.3 Ga).

AN - 1820595992; 27422835 AB - Two genes, hgcA and hgcB, are essential for microbial mercury (Hg) methylation. Detection and estimation of their abundance, in conjunction with Hg concentration, bioavailability, and biogeochemistry, are critical in determining potential hot spots of methylmercury (MeHg) generation in at-risk environments. We developed broad-range degenerate PCR primers spanning known hgcAB genes to determine the presence of both genes in diverse environments. These primers were tested against an extensive set of pure cultures with published genomes, including 13 Deltaproteobacteria, nine Firmicutes, and nine methanogenic Archaea genomes. A distinct PCR product at the expected size was confirmed for all hgcAB(+) strains tested via Sanger sequencing. Additionally, we developed clade-specific degenerate quantitative PCR (qPCR) primers that targeted hgcA for each of the three dominant Hg-methylating clades. The clade-specific qPCR primers amplified hgcA from 64%, 88%, and 86% of tested pure cultures of Deltaproteobacteria, Firmicutes, and Archaea, respectively, and were highly specific for each clade. Amplification efficiencies and detection limits were quantified for each organism. Primer sensitivity varied among species based on sequence conservation. Finally, to begin to evaluate the utility of our primer sets in nature, we tested hgcA and hgcAB recovery from pure cultures spiked into sand and soil. These novel quantitative molecular tools designed in this study will allow for more accurate identification and quantification of the individual Hg-methylating groups of microorganisms in the environment. The resulting data will be essential in developing accurate and robust predictive models of Hg methylation potential, ideally integrating the geochemistry of Hg methylation to the microbiology and genetics of hgcAB IMPORTANCE: The neurotoxin methylmercury (MeHg) poses a serious risk to human health. MeHg production in nature is associated with anaerobic microorganisms. The recent discovery of the Hg-methylating gene pair, hgcA and hgcB, has allowed us to design and optimize molecular probes against these genes within the genomic DNA for microorganisms known to methylate Hg. The protocols designed in this study allow for both qualitative and quantitative assessments of pure-culture or environmental samples. With these protocols in hand, we can begin to study the distribution of Hg-methylating organisms in nature via a cultivation-independent strategy. Copyright © 2016 Christensen et al.

AN - 1817050201; 25583276 AB - Melioidosis is caused by Burkholderia pseudomallei and is an important zoonotic infectious disease causing high mortality from fulminant septicaemia in humans and a wide variety of animal species. The incidence of fatal melioidosis in zoo animals has been significant in many Thai zoos. A total number of 32 cases were evaluated throughout the Thai zoo animal populations. The highest prevalence of disease has been reported from the north-eastern region followed by the zoos in the southern part of the country, approximately 47% and 38%, respectively, while the other zoos reported sporadic infections. Herbivores and non-human primates were the most commonly affected animals with incidences of 59% and 28%, respectively. This appears to be a seasonal correlation with the highest incidence of melioidosis in zoo animals reported in the rainy season (44%) or subdivided monthly in June (19%) followed by September and November (16% and 12%, respectively). The route of infection and the incubation period still remain unclear. This retrospective study examined the clinical presentation in various zoo species, pathological findings and epidemiological data as well as conducting an in depth literature review. © 2015 Blackwell Verlag GmbH.

Here, we report two new exceptionally preserved latest Ediacaran fossil assemblages from the Deep Spring Formation at Mount Dunfee, Nevada (USA). Further, we report these occurrences in a high-resolution carbon isotope chemostratigraphic framework, permitting correlation on a regional and global scale. The lower of the two horizons, at the base of the Deep Spring Formation, hosts a body fossil assemblage that includes Gaojiashania, other vermiform body fossils, and possible Wutubus annularis interbedded with Cloudina shell beds. The upper of the two fossil horizons, in the Esmeralda Member of the Deep Spring Formation, contains Conotubus and occurs within the basal Cambrian negative carbon isotope excursion, establishing it as the youngest Ediacaran fossil assemblage discovered to date. This is the first report of Gaojiashania, Conotubus, and Wutubus in Laurentia, extending the known stratigraphic ranges and biogeographic distributions of these taxa to a global scale. These data refine the relative ages of defining characteristics of the Ediacaran-Cambrian boundary and confirm that a large perturbation to the carbon cycle and surface ocean conditions coincided with the extinction of Ediacaran organisms.

The process also flushes out unexpected sibling species hiding under long-applied scientific names, thereby clarifying and parsing previously mixed collateral data. The Barcode of Life Database has matured to an essential interactive platform for the multi-authored and multi-process collaboration. The BIN system of creating and tracking DNA sequence-based clusters as proxies for species has become a powerful way around some parts of the 'taxonomic impediment', especially in entomology, by providing fast but testable and tractable species hypotheses, tools for visualizing the distribution of those in time and space and an interim naming system for communication.This article is part of the themed issue 'From DNA barcodes to biomes'.

This variation is known to influence food selection and ingestion among non-human primates, yet no large-scale comparative study has examined the relationships between food mechanical properties and feeding strategies. Here, we present comparative data on the Young's modulus and fracture toughness of natural foods in the diets of 31 primate species. We use these data to examine the relationships between food mechanical properties and dietary quality, body mass, and feeding time. We also examine the relationship between food mechanical properties and categorical concepts of diet that are often used to infer food mechanical properties. We found that traditional dietary categories, such as folivory and frugivory, did not faithfully track food mechanical properties. Additionally, our estimate of dietary quality was not significantly correlated with either toughness or Youngʼs modulus. We found a complex relationship among food mechanical properties, body mass, and feeding time, with a potential interaction between median toughness and body mass. The relationship between mean toughness and feeding time is straightforward: feeding time increases as toughness increases. However, when considering median toughness, the relationship with feeding time may depend upon body mass, such that smaller primates increase their feeding time in response to an increase in median dietary toughness, whereas larger primates may feed for shorter periods of time as toughness increases. Our results emphasize the need for additional studies quantifying the mechanical and chemical properties of primate diets so that they may be meaningfully compared to research on feeding behavior and jaw morphology.

We ask how mechanics may constrain foraging and feeding on both plants and animals, and how various aspects of mechanical behavior could affect the feeding choices that primates make. Here, we present novel methods for the measurement of the material properties and also the employment of tried and tested methods in novel settings. This review demonstrates how mechanical investigation methods can quantify the environmental factors affecting primate locomotion to and from food, which makes up a large part of a primate's daily energy budget. We indicate that, despite the accumulation of much data on the material properties of primate foods, the introduction of new methods is allowing researchers to pursue new avenues of research and change paradigms in primate feeding ecology. Field methods are presented that could aid in the understanding of the extra-oral processing of foodstuffs by primates and enrich further studies into cognition and culture surrounding these types of behavior. We conclude that the use of in-field measurements and a greater understanding of the physics of primate environments are vital and exciting themes integral to the continued understanding of primate evolution and biology.

Fossils were recovered from a thin heterolithic unit between a shallow-marine bed and the paleosol beneath the Minshall Coal, a Middle Pennsylvanian succession deposited near the Atokan-Desmoinesian and Bolsovian-Asturian boundaries. Sedimentological indicators imply accumulation under a seasonal climate, including interbedded siltstone and sandstone deposited during flashfloods, intraclasts eroded from local sources, and charcoal produced by wildfires. The macrofloral assemblage is consistent with a dryland setting, being dominated by large, coriaceous gymnosperm leaves with mesic to xeric traits, including Cordaites spp. indet., Lesleya sp. indet., and Taeniopteris sp. cf. T. multinervia. Sphenopsids and ferns typical of the wetland biome are rare. In contrast, the microfloral assemblage is dominated by fern spores, with lesser lycopsid spores and cordaitalean pollen. The succession indicates that the dryland biome predominated during late regression, prior to the onset of perhumid conditions that resulted in peat accumulation at late lowstand. However, the abundance of palynomorphs from wetland vegetation implies gradual fragmentation of the prevailing dryland flora and replacement by the wetland biome in the transition to glacial maximum. The taphonomic and paleobiogeographic context confirms that floras adapted to seasonal moisture deficit periodically dispersed into tropical lowlands, rather than being transported from 'extrabasinal' or 'upland' environments. The precocious occurrence of Taeniopteris, more typical of Late Pennsylvanian and Permian floras, may be the earliest record of the fossil-genus, and exemplifies the association of derived plant taxa with dryland habitats. The predominance of broad-leaved gymnosperms with mesic to xeric characters suggests that dryland communities contained more slow-growing and long-lived plants than contemporaneous wetland floras.

We hypothesized that decreasing aridity would have similar effects on soil P transformations as time by increasing the rate of pedogenesis. To assess this, we examined P fractions in arid and semiarid grassland soils (0-10 cm) along a 3700 km aridity gradient in northern China (aridity between 0.43 and 0.97, calculated as 1 - [mean annual precipitation/potential evapotranspiration]). Primary mineral P declined as aridity decreased, although it still accounted for about 30% of the total P in the wettest sites. In contrast, the proportions of organic and occluded P increased as aridity decreased. These changes in soil P composition occurred in parallel with marked shifts in soil nutrient stoichiometry, with organic carbon:organic P and nitrogen:organic P ratios increasing with decreasing aridity. These results indicate increasing abundance of P relative to carbon or nitrogen along the climosequence. Overall, our results indicate a broad shift from abiotic to biotic control on P cycling at an aridity value of approximately 0.7 (corresponding to about 250 mm mean annual rainfall). We conclude that the Walker and Syers model can be extended to climosequences in arid and semiarid ecosystems and that the apparent decoupling of nutrient cycles in arid soils is a consequence of their pedogenic immaturity.

Fresh shallow valleys (FSVs) are widespread from approximately 30 to 45 degrees in both hemispheres with a high concentration in northern Arabia Terra. Valleys in northern Arabia Terra characteristically start abruptly on steeper slopes and terminate in topographic depressions at elevations corresponding to model-predicted lake levels. Longer valley systems flowed into and out of chains of paleolakes. Minimum discharges based on the dimensions of the incised channel assuming medium to coarse sand-size grains ranges from tens to hundreds of m (super 3) s (super -1) , respectively, consistent with formation via snowmelt from surface or sub-ice flows. Hydrologic calculations indicate the valleys likely formed in hundreds of years or less, and crater statistics constrain the timing of fluvial activity to between the Hesperian and middle Amazonian. Several craters with channels extending radially outward supports evidence for overflow of interior crater lakes possibly fed by groundwater. Most FSVs occur away from young impact craters which make an association with impact processes improbable. The widespread occurrence of FSVs along with their similar morphology and shared modest state of degradation is consistent with most forming during a global interval of favorable climate, perhaps contemporaneous with alluvial fan formation in equatorial and midlatitudes. Evidence for a snowmelt-based hydrology and considerable depths of water on the landscape in Arabia supports a cold, wet, and possibly habitable environment late in Martian history.

Previous spot-core drilling at Deep Sea Drilling Project Site 258 in the western MB demonstrates the presence of an expanded upper Albian-lower Campanian chalk, marl, and claystone sequence that is nearly complete stratigraphically and yields calcareous microfossils that are mostly well preserved. This sediment package and the underlying Albian volcanic claystone unit extend across most of the MB and are targeted at the primary sites, located between 850 and 3900 m water depth. Coring the Cretaceous MB sequence at different paleodepths will allow recovery of material suitable for generating paleotemperature and biotic records that span the rise and collapse of the Cretaceous hothouse (including oceanic anoxic Events [OAEs] 1d and 2), providing insight to resultant changes in deepwater and surface water circulation that can be used to test predictions from earth system models. The high-paleolatitude (60 degrees -62 degrees S) location of the sites is especially important because of the enhanced sensitivity to changes in vertical gradients and surface water temperatures. Paleotemperature proxies and other data will reveal the timing, magnitude, and duration of peak hothouse temperatures and whether there were any cold snaps that would have allowed growth of a polar ice sheet. The sites are also well-positioned to monitor the mid-Eocene-early Oligocene opening of the Tasman Gateway and the Miocene-Pliocene restriction of the Indonesian Gateway; both passages have important effects on global oceanography and climate. Comparison of the Cenomanian-Turonian OAE 2 interval that will be cored on the Great Australian Bight will establish whether significant changes in ocean circulation were coincident with OAE 2, and over what depth ranges, and whether OAE 2 in the high-latitude Southern Hemisphere was coincident with major changes in sea-surface temperature. Understanding the paleoceanographic changes in a regional context will provide a global test on models of Cenomanian-Turonian oceanographic and climatic evolution related both to extreme Turonian warmth and the evolution of OAE 2. Drilling of Early Cretaceous volcanic rocks and underlying Jurassic(?) sediments in different parts of the MB will provide information on the timing of different stages of the Gondwana breakup and the nature of the various phases of volcanism, which will lead to an improved understanding of the evolution of the NP and MB.

Movement ecology has developed rapidly over the past decade, driven by advances in tracking technology that have largely removed data limitations. Development of rigorous analytical tools has lagged behind empirical progress, and as a result, relocation data sets have been underutilized. 2. Discrete-time correlated random walk models (CRW) have long served as the foundation for analyzing relocation data. Unfortunately, CRWs confound the sampling and movement processes. CRW parameter estimates thus depend sensitively on the sampling schedule, which makes it difficult to draw sampling-independent inferences about the underlying movement process. Furthermore, CRWs cannot accommodate the multiscale autocorrelations that typify modern, finely sampled relocation data sets. 3. Recent developments in modelling movement as a continuous-time stochastic process (CTSP) solve these problems, but the mathematical difficulty of using CTSPs has limited their adoption in ecology. To remove this roadblock, we introduce the ctmm package for the R statistical computing environment. ctmm implements all of the CTSPs currently in use in the ecological literature and couples them with powerful statistical methods for autocorrelated data adapted from geostatistics and signal processing, including variograms, periodograms and non-Markovian maximum likelihood estimation. 4. ctmm is built around a standard workflow that begins with visual diagnostics, proceeds to candidate model identification, and then to maximum likelihood fitting and AIC-based model selection. Once an accurate CTSP for the data has been fitted and selected, analyses that require such a model, such as quantifying home range areas via autocorrelated kernel density estimation or estimating occurrence distributions via time-series Kriging, can then be performed. 5. We use a case study with African buffalo to demonstrate the capabilities of ctmm and highlight the steps of a typical CTSP movement analysis workflow.

Of the eastern Asian-North American disjuncts, conifers exhibit a high proportion of disjuncts between eastern Asia and western North America. Several lineages of ferns also show a recent disjunct pattern in the two areas. In flowering plants, the pattern is commonly shown in temperate elements between northeastern Asia and northwestern North America, as well as elements of the relict boreotropical and Neogene mesophytic and coniferous floras. The many cases of intercontinental biogeographic disjunctions between eastern Asia and western North America in plants supported by recent phylogenetic analyses highlight the importance of the Bering land bridge and/or the plant migrations across the Beringian region from the late Cretaceous to the late Neogene, especially during the Miocene. The Beringian region has permitted the filtering and migration of certain plant taxa since the Pliocene after the opening of the Bering Strait, as many conspecific taxa or closely related species occur on both sides of Beringia.

This is especially true for native populations in the biologically rich, but sparsely distributed wetlands of the southwest United States, which are among the most imperiled systems in North America. We identified multiple Hybrid P. australis stands in the Las Vegas Wash watershed, NV, a key regional link to the Colorado River basin. Rapid urbanization in this watershed has caused striking changes in water and nutrient inputs and the distribution of wetland habitats has also changed, with urban wetlands expanding but an overall reduction in wetland habitats regionally. Native P. australis has likely been present in the Wash wetland community in low abundance for thousands of years, but today Hybrid and Native plants dominate the shoreline along much of the Wash. In contrast, Introduced P. australis is rare, suggesting that opportunities for novel hybridization events remain uncommon. Hybrid crosses derived from both the native and introduced maternal lineages are widespread, although the conditions that precluded their establishment are unknown and we did not find evidence for backcrossing. Spread of Hybrid plants is likely associated with flooding events as well as restoration activities, including revegetation efforts and construction for erosion control, that have redistributed sediments containing P. australis rhizomes. Downstream escape of Hybrid plants to Lake Mead and wetlands throughout the lower Colorado River basin is of management concern as these Hybrids appear vigorous and could spread rapidly.

It has been several decades since the last formal taxonomic examination of the genus and a number of recent genetic studies have revealed novel diversity and unique lineages within the genus. In my initial work on genetic variation in Phragmites (Saltonstall in Proc Nat Acad Sci 99:2445-2449, 2002), I came up with a naming scheme for identifying chloroplast DNA haplotypes which combined unique sequences at two loci, designated by numbers, to form haplotypes, designated by letters. Here I describe this naming system in more detail, explain how it has evolved over time as more genetic data has become available, provide a summary of all haplotypes currently available on GenBank, and address some common misunderstandings about how the haplotypes are named.

However, dispersal distance is often difficult to measure. Patterns of genetic relatedness can be interpreted to understand realized genetic dispersal distances, which can then be applied to management. We analyzed patterns of microsatellite relatedness using Mantel correlograms and used them to estimate realized dispersal distance for the invasive wetland grass, Phragmites australis. We found that genetic relatedness declined quickly with increasing distance, decreasing to the level of the mean subestuary genetic relatedness by 100 m and to nearly zero by 500 m. We interpret this to indicate that most dispersal is <100 m and very little dispersal extends beyond 500 m. This suggests that management of P. australis may need to consider dispersal from stands up to 500 m from an area that is being managed, perhaps at the scale of whole subestuaries. Results of this study demonstrate that analysis of dispersal patterns can be used to develop landscape-scale approaches to the management of invasive species.

We used the invasion of Chesapeake Bay wetlands by P. australis as a model system to examine the effects of regional and local stressors on plant invasions. We summarized digital maps of the distributions of P. australis and of potential stressors (especially human land use and shoreline armoring) at two spatial scales: for 72 subestuaries of the bay and their local watersheds and for thousands of 500 m shoreline segments. We developed statistical models that use the stressor variables to predict P. australis prevalence (% of shoreline occupied) in subestuaries and its presence or absence in 500 m segments of shoreline. The prevalence of agriculture was the strongest and most consistent predictor of P. australis presence and abundance in Chesapeake Bay, because P. australis can exploit the resulting elevated nutrient levels to enhance its establishment, growth, and seed production. Phragmites australis was also positively associated with riprapped shoreline, probably because it creates disturbances that provide colonization opportunities. The P. australis invasion was less severe in areas with greater forested land cover and natural shorelines. Surprisingly, invasion was low in highly developed watersheds and highest along shorelines with intermediate levels of residential land use, possibly indicating that highly disturbed systems are uninhabitable even to invasive species. Management strategies that reduce nutrient pollution, preserve natural shorelines, and limit nearshore disturbance of soils and vegetation may enhance the resilience of shorelines to invasion.

The timing of signals is shaped by selective pressures including mate preferences, predation, and competition. In many insect communities, male calling to attract females is persistent and pervasive, and signal timing interactions among individuals are relatively common. In Neotropical forests, many katydid species are represented in the acoustic environment, but calls are usually short (<40 ms) and infrequent (<10 s of sound per individual per night), characteristics that have likely evolved in response to intense predation by insectivorous bats. We test two alternative hypotheses about signal timing in environments where signaling is rare and costly, either that timing is absent due to the unpredictable nature of the signals or that the rarity of signals places a premium on signal timing and attention to the acoustic environment. We tested these hypotheses by broadcasting conspecific calls, heterospecific calls, and silence to eight species of katydids and measuring calling activity and call timing in each playback treatment. All species changed the amount or timing of calling (or both) as a result of the playbacks, but species responded differently to playbacks, with some calling more or less during specific treatments and some showing differences in the timing of calls relative to playbacks. Although short latency signal timing was not observed, this study shows that Neotropical forest katydids are responsive to their acoustic environment despite an exceptionally low rate of signaling. In many species, males produce signals to attract females, and studies show that the timing of these signals relative to other stimuli can play an important role in mate attraction and predator avoidance. Most of these studies have investigated species that are prolific signalers, due to the ease of collecting data. Here, we extend these theories and test them in Neotropical forest katydids, which produce very short and sporadic acoustic signals. We find that these insects do not display the fast competitive interactions seen in more prolific signalers, but still adjust both the timing and amount of calling in response to what they hear. These findings reveal that insects that signal rarely are still attending to the signaling of others and that their behavior can be strongly affected by the signals of other insects, including insects of other species.

However, many such species are well represented in museum collections assembled before the molecular era. Development of techniques to recover genetic data from these invaluable specimens will benefit biodiversity science. Using a mixture of freshly preserved and historical tissue samples, and a sequence capture probe set targeting >5000 loci, we produced high-confidence genotype calls on thousands of single nucleotide polymorphisms (SNPs) in each of five South-East Asian bird species and their close relatives (N = 27-43). On average, 66.2% of the reads mapped to the pseudo-reference genome of each species. Of these mapped reads, an average of 52.7% was identified as PCR or optical duplicates. We achieved deeper effective sequencing for historical samples (122.7) compared to modern samples (23.5). The number of nucleotide sites with at least 8 sequencing depth was high, with averages ranging from 0.89 10 super(6) b p (Arachnothera, modern samples) to 1.98 10 super(6) b p (Stachyris, modern samples). Linear regression revealed that the amount of sequence data obtained from each historical sample (represented by per cent of the pseudo-reference genome recovered with greater than or equal to 8 sequencing depth) was positively and significantly (P less than or equal to 0.013) related to how recently the sample was collected. We observed characteristic post-mortem damage in the DNA of historical samples. However, we were able to reduce the error rate significantly by truncating ends of reads during read mapping (local alignment) and conducting stringent SNP and genotype filtering.

This probes set was designed from seven mammalian orders and tested to determine the utility for enriching degraded DNA. We generated 63 mitogenomes representing five orders and 22 genera of mammals that yielded varying coverage ranging from 0 to >5400X. Based on a threshold of 70% mitogenome recovery and at least 10 average coverage, 32 individuals or 51% of samples were considered successful. The estimated sequence divergence of samples from the probe sequences used to construct the array ranged up to nearly 20%. Sample type was more predictive of mitogenome recovery than sample age. The proportion of reads from each individual in multiplexed enrichments was highly skewed, with each pool having one sample that yielded a majority of the reads. Recovery across each mitochondrial gene varied with most samples exhibiting regions with gaps or ambiguous sites. We estimated the ability of the probes to capture mitogenomes from a diversity of mammalian taxa not included here by performing a clustering analysis of published sequences for 100 taxa representing most mammalian orders. Our study demonstrates that a general array can be cost and time effective when there is a need to screen a modest number of individuals from a variety of taxa. We also address the practical concerns for using such a tool, with regard to pooling samples, generating high quality mitogenomes and detail a pipeline to remove chimeric molecules.

Simultaneous identification of the ectoparasite species, the wildlife host that provided their most recent blood meal(s), and their pathogen load would greatly facilitate the understanding of the complex transmission dynamics of vector-borne diseases. Currently, these identifications are principally performed using multiple polymerase chain reaction (PCR) assays. We developed an assay (EctoBaits) based on in-solution capture paired with high-throughput sequencing to simultaneously identify ectoparasites, host blood meals and pathogens. We validated our in-solution capture results using double-blind PCR assays, morphology and collection data. The EctoBaits assay effectively and efficiently identifies ectoparasites, blood meals, and pathogens in a single capture experiment, allowing for high-resolution taxonomic identification while preserving the DNA sample for future analyses.

Constraining mare volcanic history therefore provides a window into the endogenic processes responsible for shaping the Moon. Due to the low magma viscosity and the associated thin nature of lava units, the majority of mare surface structures are masked and subdued by impact regolith. Subtle individual mare flow morphologies, coupled with spatial limitations in the use of crater size distributions to distinguish surface units close in age, restrict our understanding of mare stratigraphy. Earth-based 70 cm wavelength (P band) radar can reveal features beneath the regolith and highlight very subtle changes in the ilmenite content of the flows, providing a unique means to map mare units. Here we map volcanic units in Mare Imbrium using high-resolution (200 m/pixel), Earth-based P band data. Situated within the heat-producing potassium, rare earth element, and phosphorus terrane, Mare Imbrium experienced some of the most long-lived (and recent) lunar volcanism, and its surface exhibits a significant diversity of basaltic chemistry. Our investigation identifies at least four distinct stages of volcanic activity, originating from multiple sources within Imbrium. The most recent of these stages comprises extensive, yet relatively thin volcanic flow units that left remnant kipukas of older mare material distributed across much of the basin. From a future mission perspective, it may be possible to collect samples expressing a wide range in age from small areas of Mare Imbrium. Our map also places important constraints on the interpretation of the Chang'e-3 Lunar Penetrating Radar measurements. Abstract Copyright (2016), . American Geophysical Union. All Rights Reserved.

The descriptions are based on a fossil leaf that was first reported in 1895 but identified as a fragment of a fossil fern. The new genus and species of angiosperm, Vernifolium tenuiloba Jud and Sohn, gen. et sp. nov., was likely herbaceous and is based on a twice odd-pinnatifid leaf with glandular teeth at the tips of the lobes, and minute resin bodies covering the lamina. Leaf architectural features and sedimentological context indicate that this leaf was produced by an herbaceous eudicot angiosperm, possibly associated with Ranunculales. The leaf mine Phytomyzites wardi Sohn and Jud, ichnosp. n. is a full depth linear-blotch mine with frass, a trace of puparium inside the blotch mine section, and feeding/oviposition-related puncture marks. The features of the mine are most consistent with those produced by agromyzid flies. This fossil extends the record of agromyzid flies by about 40 myr. Furthermore, data from molecular studies suggests that the ancestral hosts for agromyzid flies are asterids, with several later host-shifts to feeding on Ranunculaceae, but this fossil provides evidence that agromyzid flies or their ancestors were feeding on herbaceous basal eudicots similar to modern herbaceous ranunculids during the Early Cretaceous, prior to the appearance and diversification of asterids.

We examine the possibility and some consequences of episodes of extended, weak ash venting at the rhyolitic Mono-Inyo chain in Eastern California. We describe ash-filled cracks within one of the youngest domes, Panum Crater, which provide a textural record of ash venting during dome effusion. We use synchrotron-based X-ray computed tomography to characterize the particles in these tuffisites. Particle sizes in well-sorted tuffisite layers agree well with grain size distributions observed during weak ash venting at Soufriere Hills Volcano, Montserrat, and yield approximate upper and lower bounds on gas velocity and mass flux during the formation of those layers. We simulate ash dispersal with Ash3d to assess the consequences of long-lived Mono-Inyo ash venting for ash deposition and the accompanying volcanic hazards. Our results highlight the sensitivity of large-scale outcomes of volcanic eruptions to small-scale processes.

Tropical terrestrial organisms are thought to live very near their upper thermal tolerance limits, and such small thermal safety factors put them at risk from global warming. However, little is known about the thermal tolerances of tropical marine invertebrates, how they vary across different life stages, and how these limits relate to environmental conditions. We tested the tolerance to acute heat stress of five life stages of the tropical sea urchin Lytechinus variegatus collected in the Bahia Almirante, Bocas del Toro, Panama. We also investigated the impact of chronic heat stress on larval development. Fertilization, cleavage, morula development, and 4-armed larvae tolerated 2-h exposures to elevated temperatures between 28-32 degree C. Average critical temperatures (LT sub(50)) were lower for initiation of cleavage (33.5 degree C) and development to morula (32.5 degree C) than they were for fertilization (34.4 degree C) or for 4-armed larvae (34.1 degree C). LT sub(50) was even higher (34.8 degree C) for adults exposed to similar acute thermal stress, suggesting that thermal limits measured for adults may not be directly applied to the whole life history. During chronic exposure, larvae had significantly lower survival and reduced growth when reared at temperatures above 30.5 degree C and did not survive chronic exposures at or above 32.3 degree C. Environmental monitoring at and near our collection site shows that L. variegatus may already experience temperatures at which larval growth and survival are reduced during the warmest months of the year. A published local climate model further suggests that such damaging warm temperatures will be reached throughout the Bahia Almirante by 2084. Our results highlight that tropical marine invertebrates likely have small thermal safety factors during some stages in their life cycles, and that shallow-water populations are at particular risk of near future warming. We tested critical upper thermal limits for various life stages of the tropical urchin L. variegatus and found that early embryonic development (but not fertilization) appears to be the stage most susceptible to acute thermal stress. Growth and survival of larvae raised under a range of temperatures show that they may already occasionally experience conditions that reduce growth and survival at our study site. These results are important because global warming will likely heat tropical nearshore waters and could extirpate species with low thermal tolerances like these important ecosystem engineers.

Collectively referred to as the 'twilight zone', depths below ~30-50 m are home to many species of reef fishes that are absent from shallower depths, including many undescribed and endemic species. We currently lack even a basic understanding of the diversity and evolutionary origins of fishes on tropical mesophotic reefs. Recent submersible collections in the Caribbean have provided new specimens that are enabling phylogenetic reconstructions that incorporate deep-reef representatives of tropical fish genera. Here, we investigate evolutionary depth transitions in the family Gobiidae (gobies), the most diverse group of tropical marine fishes. Using divergence-time estimation coupled with stochastic character mapping to infer the timing of shallow-to-deep habitat transitions in gobies, we demonstrate at least four transitions from shallow to mesophotic depths. Habitat transitions occurred in two broad time periods (Miocene, Pliocene-Pleistocene), and may have been linked to the availability of underutilized niches, as well as the evolution of morphological/behavioural adaptations for life on deep reefs. Further, our analysis shows that at least three evolutionary lineages that invaded deep habitats subsequently underwent speciation, reflecting another unique mode of radiation within the Gobiidae. Lastly, we synthesize depth distributions for 95 species of Caribbean gobies, which reveal major bathymetric faunal breaks at the boundary between euphotic and mesophotic reefs. Ultimately, our study is the first rigorous investigation into the origin of Caribbean deep-reef fishes and provides a framework for future studies that utilize rare, deep-reef specimens.

Protected areas with their buffer zones and the corridors that connect them are cornerstones of modern conservation actions to maintain the biodiversity we have and restore what we have lost. Policy and governance to guide the establishment and management of protected areas and supporting buffer zones is well established in the Central Indian Highlands. A policy and governance structure to create the context and enabling conditions for corridor maintenance, creation, and recovery is emerging but is constrained by the reigning land-management paradigm that separates conservation from development rather than mainstreaming species and habitat conservation into the rural development agenda. Well-nourished, healthy human populations and healthy ecosystems are inextricably linked. The worsening ecological conditions in the Central Indian Highlands can trigger the emergence of a common agenda for an inclusive, caring, and environment-friendly mode of development. The alternative is the business-as-usual scenario: a continuation of worsening ecological conditions. Entry points through the biodiversity, agriculture production, resource extraction, and economic/social sectors to enable integrated sustainable landscape management are identified. These include deepening what it means to successfully conserve a species combined with explicit threat analysis for at-risk tigers and the landscapes that supports them; landscape scenario modeling to advance communication by synthesizing diverse forms of research and articulating and evaluating alternative socio-economic futures; and the use of the smart green infrastructure process as an approach to development rather than only as a way to mitigate environmental damage. Models are presented to scale up from isolated conservation interventions to collective impact that unites supportive government partners with individuals, NGOs, and economic interests to achieve viable long-term relationships in human and natural systems to value, maintain, and recover landscape connectivity.

It is either a primary feature inherited from the subduction of oxidized oceanic crust into the mantle or a secondary feature that develops because of H (sub 2) O degassing and/or magma differentiation. Low total iron contents and high melt H (sub 2) O contents render rhyolites sensitive to any effect of H (sub 2) O degassing on ferric-ferrous ratios. Here, pre-eruptive magmatic Fe (super 2+) concentrations, measured using Fe-Ti oxides that co-crystallized with silicate phenocrysts under hydrous conditions, are compared with Fe (super 2+) post-eruptive concentrations in ten crystal-poor, fully-degassed obsidian samples; five are microlite free. No effect of H (sub 2) O degassing on the ferric-ferrous ratio is found. In addition, Fe-Ti oxide data from this study and the literature show that arc magmas are systematically more oxidized than both basalts and hydrous silicic melts from Iceland and Yellowstone prior to extensive degassing. Nor is there any evidence that differentiation (i.e., crystal fractionation, crustal assimilation) is the cause of the higher redox state of arc magmas relative to those of Iceland/Yellowstone rhyolites. Instead, the evidence points to subduction of oxidized crust and the release of an H (sub 2) O-rich fluid and/or melt with a high oxygen fugacity (f (sub O2) ), which plays a role during H (sub 2) O-flux melting of the mantle in creating basalts that are relatively oxidized.

To properly constrain the along strike timing of the Altiplano plateau surface uplift, it is necessary to know how and when the northernmost part of the Altiplano plateau evolved. We reconstruct the paleoclimate and infer the corresponding paleoelevation from the Miocene-Pliocene deposits of the Descanso-Yauri basin (14-15 degrees S) in the northernmost part of the Altiplano plateau using 4 different proxies, including carbonate clumped isotope composition (i.e., Delta (sub 47) values), carbonate delta (super 18) O (sub C) , leaf wax delta D (sub wax) and pollen assemblages from paleosol, lacustrine and palustrine carbonates and organic-rich sediments. The isotopic signatures reflect past climate conditions of mean annual air temperature (Delta (sub 47) ) and meteoric water isotope values (delta (super 18) O (sub C) , delta D (sub wax) ). Our results show that the northernmost plateau remained at low elevation (0.9 + or - 0.8 to 2.1 + or - 0.9 km) until late Miocene time ( approximately 9 Ma) characterized by approximately 15 degrees C warmer than modern temperature (mean annual air temperature of 23+ or -4 degrees C, 2sigma ), low elevation vegetation and precipitation signature with reconstructed delta (super 18) O (sub mw) (VSMOW) of -8.3 + or - 2.0 ppm from carbonate (delta (super 18) O (sub C) ) and -8.6 + or - 1.8 ppm (2sigma ) from leaf wax (delta D (sub wax) ). Modern elevations of 4 km were not reached until 5.4 + or - 1.0 Ma, as indicated by a negative shift in delta D (sub wax) (VSMOW) from -143.4 + or - 12.8 ppm (2sigma ) to -209.2 + or - 21.1 ppm (2sigma ) between 9.1 + or - 0.7 and 5.4 + or - 1.0 Ma. The timing of surface uplift of the northernmost Altiplano is consistent with the evidence for late Miocene surface uplift of the central Altiplano (16-19 degrees S) between 10 and 6 Ma, and indicates that regional scale uplift in the northern-central plateau significantly postdates the onset of surface uplift in the southern Altiplano (19-22 degrees S) between approximately 16 and 9 Ma. These results are consistent with piecemeal removal of the lower dense lithosphere, combined with possible lower/middle crustal flow from south to north in the plateau acting as the main mechanisms for the formation of the Altiplano plateau.

AN - 1802744469; 27255436 AB - The germinal epithelium, i.e., the site of germ cell production in males and females, has maintained a constant form and function throughout 500 million years of vertebrate evolution. The distinguishing characteristic of germinal epithelia among all vertebrates, males, and females, is the presence of germ cells among somatic epithelial cells. The somatic epithelial cells, Sertoli cells in males or follicle (granulosa) cells in females, encompass and isolate germ cells. Morphology of all vertebrate germinal epithelia conforms to the standard definition of an epithelium: epithelial cells are interconnected, border a body surface or lumen, are avascular and are supported by a basement membrane. Variation in morphology of gonads, which develop from the germinal epithelium, is correlated with the evolution of reproductive modes. In hagfishes, lampreys, and elasmobranchs, the germinal epithelia of males produce spermatocysts. A major rearrangement of testis morphology diagnoses osteichthyans: the spermatocysts are arranged in tubules or lobules. In protogynous (female to male) sex reversal in teleost fishes, female germinal epithelial cells (prefollicle cells) and oogonia transform into the first male somatic cells (Sertoli cells) and spermatogonia in the developing testis lobules. This common origin of cell types from the germinal epithelium in fishes with protogynous sex reversal supports the homology of Sertoli cells and follicle cells. Spermatogenesis in amphibians develops within spermatocysts in testis lobules. In amniotes vertebrates, the testis is composed of seminiferous tubules wherein spermatogenesis occurs radially. Emerging research indicates that some mammals do not have lifetime determinate fecundity. The fact emerged that germinal epithelia occur in the gonads of all vertebrates examined herein of both sexes and has the same form and function across all vertebrate taxa. Continued study of the form and function of the germinal epithelium in vertebrates will increasingly clarify our understanding of vertebrate reproduction. J.

To test the hypothesis that all major smooth plains on Mercury were emplaced by about that time, we determined crater size-frequency distributions for the nine next-largest deposits, which we interpret also as volcanic. Our crater density measurements are consistent with those of the largest areas of smooth plains on the planet. Model ages based on recent crater production rate estimates for Mercury imply that the main phase of plains volcanism on Mercury had ended by approximately 3.5 Ga, with only small-scale volcanism enduring beyond that time. Cessation of widespread effusive volcanism is attributable to interior cooling and contraction of the innermost planet. Abstract Copyright (2016), . American Geophysical Union. All Rights Reserved.

However, direct measurement of entrainment in PDCs is hampered due to hazardous conditions and opaqueness of these flows. We combine three-dimensional multiphase Eulerian-Eulerian-Lagrangian calculations with proxies of thermal conditions preserved in deposits to quantify air entrainment in PDCs at Tungurahua volcano, Ecuador. We conclude that small-volume PDCs develop a particle concentration gradient that results in disparate thermal characteristics for the concentrated bed load (>600 to approximately 800 K) and the overlying dilute suspended load ( approximately 300-600 K). The dilute suspended load has effective entrainment coefficients 2-3 times larger than the bed load. This investigation reveals a dichotomy in entrainment and thermal history between two regions in the current and provides a mechanism to interpret the depositional thermal characteristics of small-volume but frequently occurring PDCs.

Adpressed plant fossils were recovered from four distinct beds in the lowermost Staunton Formation, positioned above the Minshall Coal (uppermost Brazil Formation), part of a succession deposited near the Atokan-Desmoinesian boundary. The assemblage of 22 fossil-taxa is dominated by pteridosperms (including Neuropteris flexuosa, Macroneuropteris scheuchzeri, Alethopteris densinervosa, Neuropteris ovata, Eusphenopteris neuropteroides, and Neuropteris missouriensis) with lesser cordaitaleans (Cordaites spp. indet.) and sphenopsids (particularly Sphenophyllum cuneifolium). Lycopsids are uncommon, and ferns are rare. In contrast, the microfloral assemblage from the Minshall Coal and overlying clastic units is dominated by lycopsid and tree fern spores. Comparisons with established biozonation schemes yield different ages depending on the regional biostratigraphic framework used: (1) latest Bolsovian (Radiizonates difformis Biozone, American microfloras); (2) latest Bolsovian or earliest Asturian ('Neuropteris' rarinervis Biozone, Appalachian Basin macrofloras); or (3) earliest Asturian (Linopteris obliqua Biozone, European macrofloras). The placement and correlation of the Bolsovian-Asturian and Atokan-Desmoinesian boundaries, which have traditionally been equated by palynology, are evaluated in the context of this discordance. Several revised stratigraphic scenarios are proposed for this interval in the Illinois Basin, which is being increasingly recognized as a time of significant environmental change throughout Euramerica. Homotaxial comparisons with European macrofloral assemblages indicate that, of the 18 biological taxa recorded, between 14 and 17 (78-94%) also are common in coeval wetland deposits in Europe. The similarities exemplify the spatial conservatism and low diversity of wetland plant communities over vast areas of tropical Euramerica, a manifestation of the intrinsically stressful conditions that characterize such habitats, and indicates that neither the Laurentian Shield nor the Appalachian-Variscan Mountains were an insurmountable barrier to plant dispersal during the Middle Pennsylvanian.

Stardust cometary samples were collected in a low-density, nanoporous silica aerogel making their study technically challenging. This article demonstrates the identification, exposure, and elemental composition analysis of particles analogous to those collected by NASA's Stardust mission using in-situ SEM techniques. Backscattered electron imaging is shown by experimental observation and Monte Carlo simulation to be suitable for locating particles of a range of sizes relevant to Stardust (down to submicron diameters) embedded within silica aerogel. Selective removal of the silica aerogel encapsulating an embedded particle is performed by cryogenic NF (sub 3) -mediated electron beam-induced etching. The porous, low-density nature of the aerogel results in an enhanced etch rate compared with solid material, making it an effective, nonmechanical method for the exposure of particles. After exposure, elemental composition of the particle was analyzed by energy-dispersive X-ray spectroscopy using a high spectral resolution microcalorimeter. Signals from fluorine contamination are shown to correspond to nonremoved silica aerogel and only in residual concentrations. Abstract Copyright The Meteoritical Society, 2016.

Observations from the Mars Science Laboratory Curiosity rover and the Mars Reconnaissance Orbiter reveal that Mars hosts a third stable wind-driven bedform, with meter-scale wavelengths. These bedforms are spatially uniform in size and typically have asymmetric profiles with angle-of-repose lee slopes and sinuous crest lines, making them unlike terrestrial wind ripples. Rather, these structures resemble fluid-drag ripples, which on Earth include water-worked current ripples, but on Mars instead form by wind because of the higher kinematic viscosity of the low-density atmosphere. A reevaluation of the wind-deposited strata in the Burns formation (about 3.7 billion years old or younger) identifies potential wind-drag ripple stratification formed under a thin atmosphere.

The tentative referral of a specimen to a small megatherioid sloth, Hyperleptus?, from the early-middle Miocene Castilletes Formation, suggests affinities of this fauna with the distant Santa Cruz Formation and documents a large latitudinal distribution for this taxon. The late Pliocene Ware Formation is much more diverse, with five distinct taxa representing every family of 'ground sloths'. This diversity is also remarkable at the ecological level, with sloths spanning over two orders of magnitude of body mass and probably having different feeding strategies. Being only a few hundred kilometres away from the Isthmus of Panama, and a few hundred thousand years older than the classically recognized first main pulse of the Great American Biotic interchange (GABI 1), the Ware Formation furthermore documents an important fauna for the understanding of this major event in Neogene palaeobiogeography. The sloths for which unambiguous affinities were recovered are not closely related to the early immigrants found in North America before GABI 1. Abstract Copyright The Palaeontological Association.

Morphologically disparate Palaeogene fossils suggest considerable early experimentation, but these flattened specimens often preserve limited information. We present a three-dimensionally preserved beaked tetraodontiform from the early Eocene (c. 53 Ma) London Clay Formation, UK. Approximately coeval with the oldest crown tetraodontiforms, Ctenoplectus williamsi gen. et sp. nov. presents an unprecedented combination of characters, pairing a fused beak-like dentition with prominent dorsal-fin spines that insert atop transversely-expanded pterygiophores roofing the skull. Bayesian total-evidence tip-dating analysis indicates that Ctenoplectus represents the sister lineage of Triodontidae and highlights considerable levels of homoplasy in early tetraodontiform evolution. According to our dataset, rates of morphological character evolution were elevated at the origin of crown Tetraodontiformes, especially within gymnodonts, but declined after the principal body plans were established. Such 'early burst' patterns are regarded as a hallmark of adaptive radiations, but are typically associated with diversification at smaller spatiotemporal scales. However, denser sampling of Neogene and Recent taxa is needed to confirm this pattern. Abstract Copyright (2010), John Wiley & Sons, Ltd.

It contains unsupported radiogenic isotopes of He, Ne, Kr, Xe, and Pb. Here we show that these, and the radiation-related defects introduced to the diamond structure, are a result of uranium precipitation, with no isotopic or spectroscopic evidence of Th enrichment. The daughter products are unsupported due to Proterozoic U remobilization. Combining existing carbonado Pb isotope data with recent studies of the geochronology of the tectonic evolution of the Sao Francisco craton (eastern South America) reveals that the most likely scenario is Paleoarchean uranium enrichment of carbonado, followed by Mesoproterozoic uranium dissolution. Under all possible scenarios, the carbonado radiation damage history requires U mobilization in the Mesoarchean or late Paleoarchean. This is consistent with recent studies of South Africa and India Mesoarchean paleosols, which also show evidence for local oxygen activity greater than that of the Archean atmosphere and ocean. While those studies rely on whole-rock trace element and transition metal stable isotope measurements, this combination of crystallographic defects, sedimentary geochronology, and radiogenic isotopes supports the same conclusions of nonmarine, near-surface Archean oxygen enhancement.

Of particular interest is the potential intersection of distal crater deposits and tesserae, highly deformed landforms that may be the oldest materials on Venus. The composition of tesserae is unknown, but is key to understanding whether water played a role in crustal differentiation. Thus, tesserae are ideal sites for future landed missions to identify possible felsic materials, but the short lifespan of surface landers means that efforts must be made to avoid contaminating surface materials from craters. Here we develop a method to detect distal crater ejecta on tessera terrain across Venus using NASA Magellan radar data. Our results show that fine-grained ejecta are unevenly distributed in the tesserae with respect to nearby craters. Many tesserae within a few hundred kilometers of plains craters do not have evidence for thick (>5-10 cm) mantling material, indicating that eolian or mass-wasting processes have moved the debris off the highland ridge slopes. At Sudenitsa Tesserae, within the young Beta-Atla-Themis region, we observe a radar signature of mantling debris, but there is no apparent source crater to which this material can be traced. We infer that the source crater has been resurfaced by volcanic activity within the past 80 m.y., and suggest that similar fine-grained ejecta deposits may have built up over time in other tesserae across Venus.

Evolutionary patterns at geologic timescales inform expectations about the relationship between consumers and productivity, but it is very difficult to track productivity through time with direct, quantitative measures. Based on previous work that used the maximum body size of Cenozoic marine invertebrate assemblages as a proxy for benthic productivity, we investigated how the maximum body size of Cenozoic marine mammals, in two feeding guilds, evolved over comparable temporal and geographical scales. First, maximal size in marine herbivores remains mostly stable and occupied by two different groups (desmostylians and sirenians) over separate timeframes in the North Pacific Ocean, while sirenians exclusively dominated this ecological mode in the North Atlantic. Second, mysticete whales, which are the largest Cenozoic consumers in the filter-feeding guild, remained in the same size range until a Mio-Pliocene onset of cetacean gigantism. Both vertebrate guilds achieved very large size only recently, suggesting that different trophic mechanisms promoting gigantism in the oceans have operated in the Cenozoic than in previous eras.

We used a combination of elemental analysis, X-ray absorption spectroscopy, hydrolytic enzyme assays, and stable S isotope ratios to examine S in soil and leaf tissue along the 120,000-year Franz Josef chronosequence, New Zealand. Total soil S concentrations increased during the early stages of pedogenesis and then declined as soils aged. There was little variation in soil N:S ratios along the chronosequence other than in the youngest (5 year old) soil, although the carbon (C):S ratio increased markedly in the oldest soils and the P:S ratio decreased continuously along the chronosequence. Foliar S concentrations and N:S ratios varied widely among common plant species but did not change consistently with increasing soil age, although foliar P:S declined for several species in the older stages of the chronosequence. The chemical nature of soil organic S extracted from mineral and organic horizons and determined by S K-edge X-ray absorption near-edge fine-structure (XANES) spectroscopy was dominated by C-bonded S distributed approximately equally in highly-reduced and intermediate oxidation states, although ester-bonded S was also abundant throughout the chronosequence. Soil sulfatase activity expressed on a soil C basis was highest in young soils, indicating low S availability in the early stage of pedogenesis. Enzymatic C:S and N:S ratios varied little during ecosystem development, although the enzymatic P:S ratio increased continuously along the chronosequence. Stable S isotope ratios ( delta super(34)S) increased along the chronosequence, particularly in the early stages of pedogenesis, reflecting a shift in S inputs from primary mineral S to oceanic sulfate in atmospheric deposition. Overall, this first comprehensive assessment of S along a long-term soil chronosequence suggests that S availability is low in the earliest stage of pedogenesis, but then remains stable throughout the progressive and retrogressive phases of ecosystem development, despite pronounced shifts in the chemistry and dynamics of other nutrients.

However, life-history traits may interact with climate to influence species ranges, potentially accelerating or slowing range shifts in response to climate change. Tropical mangroves have expanded their ranges poleward in the last three decades. Here, we report on a shift at the range edge in life-history traits related to reproduction and dispersal. With a common garden experiment and field observations, we show that Rhizophora mangle individuals from northern populations reproduce at a younger age than those from southern populations. In a common garden at the northern range limit, 38% of individuals from the northernmost population were reproductive by age 2, but less than 10% of individuals from the southernmost population were reproductive by the same age, with intermediate amounts of reproduction from intermediate latitudes. Field observations show a similar pattern of younger reproductive individuals toward the northern range limit. We also demonstrate a shift toward larger propagule size in populations at the leading range edge, which may aid seedling growth. The substantial increase in precocious reproduction at the leading edge of the R. mangle range could accelerate population growth and hasten the expansion of mangroves into salt marshes. Mangrove species are expanding their ranges poleward. The red mangrove, Rhizophora mangle, has developed precocious reproduction in its northern populations. Plants in these populations are reproductive in the first few years of life, instead of the 5-10 years it takes to reach reproductive maturity in other parts of the species' range.

In this study, we measure species composition and abundance for soft-sediments to assess the contribution of NIS to multiple dimensions of community structure, focusing on one of the most highly invaded bays in the world, San Francisco Bay. Benthic macrofauna was sampled in the high salinity, muddy shallow subtidal (2 m depth) across 10 sites, using replicate 0.1 m super(2) Van Veen grabs. Invertebrates retained on a 1 mm sieve were identified, counted, and used to estimate the overall contribution of NIS to (a) abundance (b) species richness, and (c) community similarity. Soft-sediment communities were dominated numerically by NIS, which accounted for 76 % of all organisms detected and had a mean bay-wide abundance that was three and half-fold higher than native biota. Overall, NIS contributed to 36 % of observed taxa and 24-29 % of total estimated regional diversity. Native species accounted for 21 % of total abundance and 45 % of total species richness. Compared to native species, NIS occurred more frequently among samples and also explained more of the variation in community structure among sites. NIS dominate several key attributes of the soft-sediment infaunal community in San Francisco Bay. Percent contribution of NIS to species richness was at least two-fold higher than reported from two decades ago. Unique to this bay, these measures establish a quantitative baseline on the state of invasions and provide an important model for evaluating the extent of NIS in estuaries. Application of this approach across estuaries, with repeated measures over time, is critically needed to advance scientific understanding of invasions and also evaluation of efficacy and gaps in management to reduce new invasions.

In the present study, analysis of a fossil rove beetle (Coleoptera: Staphylinidae) from the Kishenehn Formation document preservation of zinc, a metal often used to harden the cutting surfaces of mandibles in extant insects, localized to the mandibles of the fossil insect. Scanning electron microscopy and energy-dispersive X-ray spectroscopy demonstrate that the carbonaceous bodies of preserved insects are physically homogeneous, composed primarily of carbon, and are distinct from the adjacent microbial mat within which the insects are thought to have been preserved. The microbial mat that covered the fossil insects is shown to consist of, in part, well-consolidated silicates. This thin layer, while completely transparent when wet, obscures the fossil when dry. The in situ preservation of components such as mandibular zinc and mosquito host blood-derived heme demonstrate that the carbonaceous bodies of Kishenehn Formation fossil insects contain some portion of their original contents. The thin layer of silicate-embedded mat may function to stabilize the fossil and its molecular components and may explain, in part, the exceptional preservation of the Kishenehn Formation fossils.

All specimens were collected from the Lower Cretaceous of Yixian Formation, Jehol Biota at Huangbanjigou, Beipiao City, western Liaoning Province, China. The forewing of Shoushida infera sp. nov. has a rudimentary "X" pattern, formed by veins of Rs, Rs (sub 1) , Rs (sub 2) and 2r-rs, which is similar to but slightly different from that of Shoushida regilla Liu, Shih et Ren, 2009. Consistent with the phylogeny of Pelecinidae reported by Shih et al., 2010, this new species and S. regilla represent a transition between basal and crown pelecinids and the rudimentary "X" pattern evolved later to a more developed and robust "X" pattern in more derived pelecinids. In addition, the long petiole of the basalmost segment of metasoma, present in the male Stelepelecinus longus gen. et sp. nov., is documented for the first time, suggesting a likely Early Cretaceous origination of metasomal evolution leading to the thin and long petiole structure in the extant male Pelecinus thoracicus. We proposed two probable pathways of the transformation of the pelecinid male metasoma from the most plesiomorphic state to the more apomorphic states. Abstract Copyright (2016) Elsevier, B.V.

Anecdotal observations over the last 80 years have suggested that intertidal neritid snails may produce encapsulated embryos able to significantly delay hatching. The cause for delays and the cues that trigger hatching are unknown, but temperature, salinity, and wave action have been suggested to play a role. We followed individual egg capsules of Nerita scabricosta in 16 tide pools to document the variation in natural time to hatching and to determine if large delays in hatching occur in the field. Hatching occurred after about 30 d and varied significantly among tide pools in the field. Average time to hatching in each pool was not correlated with presence of potential predators, temperature, salinity, or pool size. We also compared hatching time between egg capsules in the field to those kept in the laboratory at a constant temperature in motionless water, and to those kept in the laboratory with sudden daily water motion and temperature changes. There was no significant difference in the hatching rate between the two laboratory treatments, but capsules took, on average, twice as long to hatch in the laboratory as in the field. Observations of developing embryos showed that embryos in the field develop slowly and continuously until hatching, but embryos in the laboratory reach the hatching stage during the first month of development and remain in stasis after that. Instances of hatching plasticity in benthic marine invertebrates, like the one in N. scabricosta, could greatly enhance our ability to investigate the costs and benefits of benthic versus planktonic development, a long-standing area of interest for invertebrate larval biologists.

We provide an overview of Quaternary extinctions and compare mammalian extinction events on continents and islands after human arrival in system-specific prehistoric and historic contexts. We highlight the role of body size and life-history traits in these extinctions. We find a significant size-bias except for extinctions on small islands in historic times. Using phylogenetic regression and classification trees, we find that while life-history traits are poor predictors of historic extinctions, those associated with difficulty in responding quickly to perturbations, such as small litter size, are good predictors of prehistoric extinctions. Our results are consistent with the idea that prehistoric and historic extinctions form a single continuing event with the same likely primary driver, humans, but the diversity of impacts and affected faunas is much greater in historic extinctions.

We present a multi-proxy paleoenvironmental reconstruction of a terrestrial ecosystem in central Pangea of Lopingian age. The reconstruction is based on biological and physical data from the Moradi Formation, located in the Tim Mersoi sub-Basin, northern Niger. Paleosols and sedimentological evidence indicate that the prevailing climate was semi-arid to very arid with marked intervals of high water availability. Carbon stable isotope data from organic matter and paleosols suggest that both the soil productivity and actual evapotranspiration were very low, corresponding to arid conditions. Histological analysis of pareiasaur bones shows evidence of active metabolism and reveals distinct growth marks. These interruptions of bone formation are indicative of growth rhythms, and are considered as markers for contrasting seasonality or episodic climate events. The macrofossil floras have low diversity and represent gymnosperm-dominated woodlands. Most notable are ovuliferous dwarf shoots of voltzian conifers, and a 25-m long tree trunk with irregularly positioned branch scars. The combined biological and physical evidence suggests that the Moradi Formation was deposited under a generally arid climate with recurring periods of water abundance, allowing for a well-established ground water-dependent ecosystem. With respect to its environment, this system is comparable with modern ecosystems such as the southern African Namib Desert and the Lake Eyre Basin in Australia, which are discussed as modern analogues.

The objective of this study was to isolate, quantify, and characterize residual P following Hedley fractionation in a range of Andisols under grazed pasture by (super 31) P nuclear magnetic resonance (NMR) spectroscopy. Residual P accounted for 45-63% of the total soil P, of which 53-77% was inorganic orthophosphate. Organic P accounted for 21-42% of the residual P, the majority of which occurred as phosphomonoesters including myo- (16% of the residual P) and scyllo-inositol hexakisphosphate (10% of the residual P). No phosphodiesters were detected in the residual fraction. We conclude that residual P in Andisols consists of a mixture of inorganic P and organic P. Our findings provide the basis for the development of new approaches to improve P use efficiency in agriculture. Abstract Copyright (2016) Elsevier, B.V.

We used barnacles, a relatively well-studied taxon, to investigate the extent to which modern commercial vessels disperse biofouling species beyond their current known ranges. Location Vessels predominantly operated in the North Pacific; sampling was conducted in Los Angeles (CA), Portland (OR), Ketchikan (AK) and Apra Harbor (GU). Methods Barnacles were collected from submerged surfaces of commercial vessel hulls and identified to the lowest taxonomic unit using a combination of taxonomic and molecular phylogenetic techniques. Their known native and non-native geographical ranges were assessed and compared with the voyage history of the vessels. Results Forty distinct taxonomic groups of barnacles (22 assigned to species) were detected from 15 vessels. Six of these recognized species have a world-wide distribution, due to natural and anthropogenic dispersal. Sixteen species were on vessels with voyage routes that extend beyond the barnacles' known distributions, including 12 species sampled outside of their known range. Main conclusions A diverse suite of barnacle species is in continuous motion globally on commercial vessel hulls, and the potential scale of this transfer is underscored by the documented species richness for ship biofouling and what is known about the global fleet of vessels. We estimate roughly 680,000 separate arrival events per year for barnacle species to US ports distributed on both Atlantic and Pacific coasts. Genetic methods revealed high richness compared with previous studies, and the real rate is likely to be much higher than this because (1) it is likely that not all species on a vessel were sampled and (2) only a subset of sampled barnacles were successfully sequenced. Our limited knowledge about the total species pool in flux on ship hulls around the globe constrains our ability to analyse and interpret processes affecting species distribution patterns in the Anthropocene.

F2934 AN - 1790967260; PQ0003114552 AB - Aims To isolate, characterize and determine the antibacterial activities of compounds produced by the endophytic fungus Diaporthe sp. F2934, cultivated on malt extract agar. Methods and Results The fungus was cultivated aseptically in Petri dishes containing malt extract agar at 25 degree C for 15 days. Crude extract was obtained from mycelium using ethyl acetate and sonication, and was fractioned using classic chromatography and HPLC. The structures of phomosines and chromanones were established by NMR experiments including HMQC, HMBC and COSY. Their molecular formulas were determined by ESI-TOFMS. We obtained six compounds: (1) 4H-1-benzopyra-4-one-2,3-dihydro-5-hydroxy-2,8-dim etyl, (2) 4H-1-benzopyran-4-one-2,3-dihydro-5-hydroxy-8-(hyd roxylmethyl)-2-methyl, (3) 4H-1-benzopyra-4-one-2,3-dihydro-5-methoxyl-2,8-di metyl, (4) phomosine A, (5) phomosine D and (6) phomosine C. Isolated compounds 1, 2 and 5 were inactive against 15 micro-organisms, but phomosines A and C were active against diverse Gram-negative and Gram-positive bacteria. Conclusions A group of new chromanones and known phomosines have been isolated from the genus Diaporthe (Diaporthe sp. F2934). The results obtained confirm the wide chemical diversity produced by endophytic fungi, specifically the genus Diaporthe. In addition, phomosines A and C may be considered as antimicrobial agents that can be used to guide the development of new antibiotics. Significance and Impact of the Study Our phylogenetic analysis places Diaporthe sp. F2934 as sister to the Diaporthe cynaroidis clade. Three chromanones were isolated and identified, for the first time, using crude extract obtained from Diaporthe F2934. From this extract phomosines A, C and D were also purified. Regarding Staphylococcus aureus, the inhibition zone diameter (IZD) for phomosine A was 20% higher than the standard drug, vancomycin. When cultivated as described here, Diaporthe sp. F2934 produced new and antimicrobial compounds.

As such, diagnosable subspecies are increasingly recognized as an important unit for conservation. Differentiating among subspecies can be particularly difficult in ecosystems characterized by recent phenotypic divergence, such as the tidal marshes of North America. These systems require approaches that can capture selective changes which occurred over only a few millennia as species adapted to new habitats following the Holocene glacial retreat. Here we test for genetic differentiation in morphologically distinct tidal-marsh-endemic subspecies of the swamp sparrow (Melospiza georgiana) using nuclear microsatellites. This case study serves as a test approach for the quantification of conservation units for tidal marsh ecosystems. Though prior surveys of mtDNA variation showed no detectable phylogeographic structure, we found evidence of genetic differentiation in seven microsatellite loci between two M. georgiana subspecies. The most likely model of population structure suggested two clusters in western Maryland/Pennsylvania and Delaware/Chesapeake Bays, with a zone of uncertain population assignment in New Jersey. The microsatellite intergrade zone is broader than the known area of morphological intergrades. We show that microsatellites can be used to support a subspecific status for tidal-marsh taxa such as the swamp sparrow, where changing post-glacial environments likely selected for locally adapted traits while neutral genetic structure is weak. This approach thus allows for the identification and conservation of hot spots that foster ongoing evolutionary change.

The effects of signalling heterospecific neighbours on the risks of parasitism and predation AN - 1808686797; PQ0003220447 AB - Although males often display from mixed-species aggregations, the influence of nearby heterospecifics on risks associated with sexual signalling has not been previously examined. We tested whether predation and parasitism risks depend on proximity to heterospecific signallers. Using field playback experiments with calls of two species that often display from the same ponds, taungara frogs and hourglass treefrogs, we tested two hypotheses: (1) calling near heterospecific signallers attractive to eavesdroppers results in increased attention from predatory bats and parasitic midges (collateral damage hypothesis) or (2) calling near heterospecific signallers reduces an individual's predation and parasitism risks, as eavesdroppers are drawn to the heterospecifics (shadow of safety hypothesis). Bat visitation was not affected by calling neighbours. The number of frog-biting midges attracted to hourglass treefrog calls, however, rose threefold when played near tauungara calls, supporting the collateral damage hypothesis. We thus show that proximity to heterospecific signallers can drastically alter both the absolute risks of signalling and the relative strengths of pressures from predation and parasitism. Through these mechanisms, interactions between heterospecific guild members are likely to influence the evolution of signalling strategies and the distribution of species at both local and larger scales.

In this study, FDOM was measured in 92 ships arriving at Pacific ports on the US west coast and in New Zealand, and used to assess their compliance with ballast water regulations that required 95% replacement of port water to minimize invasive species risks. Fluorescence in many ships that reported BWE was significantly higher than is usual for oceanic seawater, and in several cases, significantly higher than in other ships with similar provenance and ballast water management. Pre-exchange source port conditions represented the largest source of uncertainty in the analysis, because residual coastal FDOM when highly fluorescent can significantly influence the fluorescence signature of exchanged ballast water. A meta-analysis comparing the intensities of FDOM in un-exchanged ballast tanks with calculated pre-exchange intensities assuming that ships all correctly implemented and reported BWE revealed notable discrepancies. Thus, the incidence of high-FDOM port waters was seven times lower in reality than would be expected on the basis of these calculations. The results suggest that a significant rate of reporting errors occur due to a combination of factors that may include inadequate BWE and unintentional or deliberate misreporting of ballast water management.

Miller Range (MIL) 03346 is an Antarctic nakhlite find, recovered after long exposure to Antarctic conditions. The distribution of discrete olivine etch-pits almost exclusively within a few hundred microns of allocation MIL 03346,171's documentably exposed surface suggests that they formed by terrestrial weathering in Antarctica. The small size of olivine etch-pits in MIL 03346,171 relative to commonly much larger etch-pits in even incipiently weathered terrestrial examples suggests that the duration of its exposure to weathering conditions was short, or the weathering conditions to which it was exposed did not favor olivine corrosion (in the form of etch-pit formation), or both. Time-scales for the formation of etch-pits, estimated from experimentally determined dissolution rates of olivine over a range of pHs, are comparable to the measured terrestrial age of the meteorite and short relative to the time available for possible similar corrosion on Mars. Etch-pits of the observed size on MIL 03346 olivine phenocrysts would be relatively easy to form supraglacially under brief episodic acidic Antarctic conditions, but the terrestrial age of MIL 03346 is long enough that its olivine might have been weathered to the observed state by englacial films of alkaline Antarctic water. The paucity of similar etch-pits in olivine from the interior of MIL 03346 suggests that olivine in this Mars meteorite was exposed to even less aqueous alteration after iddingsitization during its 1.3 billion years on Mars than its exterior was subjected to during its Pleistocene-Holocene exposure to Antarctic weathering conditions.

The spatial distribution of plants, which is often generated by patterns of seed recruitment, is an important determinant of population dynamics, especially for orchids with seeds that must be exposed to appropriate mycorrhizal fungi. 2. We compared the distribution and abundance of target mycorrhizal fungi detected in the soil using DNA-based molecular techniques and germination in seed packets of Goodyera pubescens, Liparis liliifolia and Tipularia discolor. 3. We further examined Tulasnella spp. associated with G. pubescens to determine whether areas with abundant host fungi resulted from multiple genets of the same species or from a single widespread fungal genet. 4. We found that target fungi were more likely to be detected using soil DNA assays than by seed germination. Based on soil DNA, fungi were more widespread than suggested by seed germination, which most often reflected the presence of abundant mycorrhizal fungi in the soil. Fungi were more likely to be abundant close to established orchids. Established plants of G. pubescens that were 50 cm apart associated with multiple fungal genets. 5. Synthesis. This study demonstrates the importance of using multiple methods to detect the distribution and abundance of target fungi and suggests that fungal 'hot spots' may be keys to the dynamics of orchid populations.

Despite their central importance to the global C cycle, their ecosystem-level C cycles are not as well-characterized as those of extra-tropical forests, and knowledge gaps hamper efforts to quantify C budgets across the tropics and to model tropical forest-climate interactions. To advance understanding of C dynamics of pantropical forests, we compiled a new database, the Tropical Forest C database (TropForC-db), which contains data on ground-based measurements of ecosystem-level C stocks and annual fluxes along with disturbance history. This database currently contains 3568 records from 845 plots in 178 geographically distinct areas, making it the largest and most comprehensive database of its type. Using TropForC-db, we characterized C stocks and fluxes for young, intermediate-aged, and mature forests. Relative to existing C budgets of extra-tropical forests, mature tropical broadleaf evergreen forests had substantially higher gross primary productivity (GPP) and ecosystem respiration (R sub(eco)), their autotropic respiration (R sub(a)) consumed a larger proportion (~67%) of GPP, and their woody stem growth (ANPP sub(stem)) represented a smaller proportion of net primary productivity (NPP, ~32%) or GPP (~9%). In regrowth stands, aboveground biomass increased rapidly during the first 20 years following stand-clearing disturbance, with slower accumulation following agriculture and in deciduous forests, and continued to accumulate at a slower pace in forests aged 20-100 years. Most other C stocks likewise increased with stand age, while potential to describe age trends in C fluxes was generally data-limited. We expect that TropForC-db will prove useful for model evaluation and for quantifying the contribution of forests to the global C cycle.

While the carbon isotope excursion is often identified in the carbon isotope ratios of bulk soil organic matter (delta (super 13) C (sub org) ), these records can be biased by factors associated with production, degradation, and sources of sedimentary carbon input. To better understand these factors, we compared delta (super 13) C (sub org) values from Paleocene-Eocene thermal maximum rocks in the southeastern Bighorn Basin, Wyoming, with those derived from leaf wax n-alkanes (delta (super 13) C (sub n-alk) ). While both delta (super 13) C (sub n-alk) and delta (super 13) C (sub org) records indicate an abrupt, negative shift in delta (super 13) C values, the carbon isotope excursions observed in bulk organic matter are smaller in magnitude and shorter in duration than those inn-alkanes. To explore these discrepancies, we modeled predicted total plant tissue carbon isotope (delta (super 13) C (sub TT) ) curves from the delta (super 13) C (sub n-alk) record using enrichment factors determined in modern C (sub 3) plants. Measured delta (super 13) C (sub org) values are enriched in (super 13) C relative to predicted delta (super 13) C (sub TT) , with greater enrichment during the Paleocene-Eocene thermal maximum than before or after. The greater (super 13) C enrichment could reflect increased degradation of autochthonous organic matter, increased input of allochthonous fossil carbon enriched in (super 13) C, or both. By comparing samples from organic-rich and organic-poor depositional environments, we infer that microbial degradation rates doubled during the Paleocene-Eocene thermal maximum, and we calculate that fossil carbon input increased approximately 28%-63%. This approach to untangling the controls on the isotopic composition of bulk soil carbon is an important development that will inform not only future studies of global carbon cycle dynamics during the Paleocene-Eocene thermal maximum hyperthermal event, but also any study that seeks to correlate or estimate duration and magnitude of past events using soil organic carbon.

Elevated oxygen fugacity (fO (sub 2) ) plays a central role in fostering crystallization of oxide minerals and thereby aids in generating the calc-alkaline trend of iron depletion that characterizes the continents. Along continental margins, arc magmas erupt through continental crust and often undergo extensive differentiation that may modify magmatic fO (sub 2) . The importance of the subducting slab and mantle wedge relative to the effects of this differentiation on the fO (sub 2) recorded by continental arc magmas remains relatively unconstrained. Here, we focus on the effect of differentiation on magmatic fO (sub 2) using a suite of 14 samples from the Central Volcanic Zone (CVZ) of the Andes where the continental crust is atypically thick (60-80 km). The samples range in composition from approximately 55 to 74 wt% SiO (sub 2) and represent the Neogene history of the arc. Samples are basaltic andesite to rhyolite and span a range of radiogenic isotopic compositions ( (super 87) Sr/ (super 86) Sr = approximately 0.705-0.712) that represent 30 to 100% crustal assimilation. We use several proxies to estimate the fO (sub 2) recorded by lavas, pumice, and scoria: (1) whole rock Fe (super 3+) /Sigma Fe ratios, (2) Fe (super 3+) /Sigma Fe ratios in quartz-hosted melt inclusions, and (3) Fe-Ti oxide oxygen-barometry. Comparison of the fO (sub 2) calculated from bulk Fe (super 3+) /Sigma Fe ratios (post-eruptive) with that derived from Fe-Ti oxides or melt inclusion Fe (super 3+) /Sigma Fe ratios (pre-eruptive), enables us to quantify the effect of syn- or post-eruptive alteration, and to select rocks for bulk analysis appropriate for the determination of pre-eruptive magmatic fO (sub 2) using a strict criterion developed here. Across our sample suite, and in context with samples from the literature, we do not find evidence for systematic oxidation due to crystal fractionation or crustal contamination. Less evolved samples, ranging from 55 to 61 wt% SiO (sub 2) , record a range of >3 orders of magnitude in fO (sub 2) , spanning the fO (sub 2) range recorded by all samples in our suite. Among these less evolved magmas, we find that those erupted from volcanic centers located closer to the trench, closer to the Benioff Zone, and with more geochemical evidence of subducted components in the mantle source (elevated La/Nb) result in magmas that record systematically higher fO (sub 2) . We conclude that the slab/mantle source can exert greater control on magmatic fO (sub 2) than processes occurring in even the thickest continental crust.

In situ oxygen isotope analyses of conodont apatite from South China enables us to reconstruct high-resolution seawater temperature records across the Permian-Triassic boundary (PTB) intervals in the upper slope (Meishan), lower slope (Shangsi), and carbonate platform (Daijiagou and Liangfengya) settings. Constrained by the latest high-precision geochronological dates and high-resolution conodont biozones, we can establish the temporal and spatial patterns of seawater temperature changes and assess their potential connections with the carbon cycle disruption and biodiversity decline. We find a rapid warming of approximately 10 degrees C during the latest Permian-earliest Triassic that postdated the onset of the negative shift in delta (super 13) C (sub carb) by approximately 81 kyr (thousand years), the abrupt decline in delta (super 13) C (sub carb) by approximately 32 kyr and the onset of mass extinction by approximately 23 kyr, which contradicts previous claims that the extreme temperature rise started immediately before or coincided with the onset of mass extinction. Our new evidence indicates that climate warming was most likely not a direct cause for the main pulse of the end-Permian mass extinction (EPME), but rather a later participant or a catalyst that increased the pace of the biodiversity decline. In addition, a prominent cooling is recorded in the earliest Changhsingian, with the main phase (a drop of approximately 8 degrees C in approximately 0.2 Ma) confined to the lower part of the Clarkina wangi zone and synchronous with the positive limb of the carbon isotope excursion (CIE) around the Wuchiapingian-Changhsingian boundary (WCB) in Meishan and Shangsi. Further long-term and high-resolution studies from other sections are needed to confirm the full contexts and underlying dynamics of the WCB "cooling event". Abstract Copyright (2016) Elsevier, B.V.

This elasmobranch assemblage provides a unique glimpse into the Caribbean bio-diversity at the onset of the Neogene. The assemblage consists of 13 taxa, of which some are reported from Miocene deposits for the very first time. There are also new records of taxa the in southern Caribbean region. The taxonomic composition of the selachian assemblage was used to conduct a paleoenvironmental and paleobathymetric analysis of the lower Uitpa Formation. The maximum likelihood estimation of paleobathymetry suggests that the lower part of the Uitpa Formation was probably accumulated at a water depth of 100 to 200 m. This indicates a rapid increase in relative sea level or basin deepening, providing new insights into the possible causes of marine biota changes in the Cocinetas Basin during the Oligocene/Miocene transition.

Ozone depletion increases incident short-wavelength ultraviolet radiation (UVB, 280-315nm) and longer (>600nm) wavelengths of photosynthetically available radiation (PAR, 400-700nm). On the other hand, the NO2 haze decreases atmospheric transmission in the long-wavelength UVA (315-400nm) and short-wavelength PAR. Here, we use the results of previous simulations of incident spectral irradiance following an ionizing radiation event to predict changes in terran productivity focusing on photosynthesis of marine phytoplankton. The prediction is based on a spectral model of photosynthetic response, which was developed for the dominant genera in central regions of the ocean (Synechococcus and Prochlorococcus), and on remote-sensing-based observations of spectral water transparency, temperature, wind speed, and mixed layer depth. Predicted productivity declined after a simulated ionizing event, but the effect integrated over the water column was small. For integrations taking into account the full depth range of PAR transmission (down to 0.1% of utilizable PAR), the decrease was at most 2-3% (depending on strain), with larger effects (5-7%) for integrations just to the depth of the surface mixed layer. The deeper integrations were most affected by the decreased utilizable PAR at depth due to the NO2 haze, whereas shallower integrations were most affected by the increased surface UV. Several factors tended to dampen the magnitude of productivity responses relative to increases in surface-damaging radiation, for example, most inhibition in the modeled strains is caused by UVA and PAR, and the greatest relative increase in damaging exposure is predicted to occur in the winter when UV and productivity are low.

At least two taxa are present in the Bissekty Formation based on different frontal and humerus morphotypes. Phylogenetic analysis based on a dataset with 348 morphological characters and including all known therizinosaurian taxa places the Bissekty taxa as derived non-therizinosaurid therizinosauroids. The Bissekty therizinosauroids are more derived than Alxasaurus elesitaiensis in the extensive pneumatization of the postcranial axial skeleton, the absence of teeth in the anterior portion of the dentary, the weak development or even absence of pits for the collateral ligaments on the manual phalanges, and the subtriangular medial aspect of the distal end of the humerus, with the entepicondyle positioned well medial to the ulnar condyle. They are less derived than Therizinosauridae in the presence of a basisphenoid recess, the absence of pneumatic openings on the anterior caudal vertebrae, the distal end of metacarpal III not being ginglymoid in dorsal view, and the separation of the femoral head from the neck of that bone by a raised ventral rim.

The Cenomanian Khodzhakul Formation in the southwestern Kyzylkum Desert has yielded isolated serrated teeth and some postcranial bones of an indeterminate troodontid. In the central Kyzylkum Desert troodontids are known from the Cenomanian Dzharakuduk Formation (Urbacodon itemirensis) and the Turonian Bissekty Formation (Urbacodon sp.). Urbacodon itemirensis is known from a single dentary whereas Urbacodon sp. is represented by isolated teeth, maxilla and dentary fragments, a partial braincase, and some postcranial bones. The troodontid affinities of Urbacodon are supported by several synapomorphies: presence of a subotic recess; reduced basal tubera placed directly under the occipital condyle; maxilla participating in the margin of the external naris; nutrient foramina on dentary situated within a deep lateral groove; dentary without distinct interdental plates; large number of small dentary and maxillary teeth; teeth constricted between root and crown; anterior dentary teeth smaller, more numerous, more closely spaced than those in the middle of the tooth row, and implanted in a groove; posterior dorsal vertebrae with tall and posterodorsally tapering neural spines; and presence of a midline sulcus on the neural arches of distal caudals. Among Troodontidae, Urbacodon resembles Byronosaurus, Gobivenator, and Xixiasaurus in the absence of serrations on the tooth crowns and having premaxillary teeth that are D-shaped in cross-section. However, phylogenetic analysis did not recover a clade of Asiatic troodontids with unserrated teeth. Abstract Copyright (2016) Elsevier, B.V.

Because of the sheer abundance of their biomass in many wetland environments of the Late Paleozoic, they may have been an important variable in the global carbon cycle and climate. However, their unusual structure has invited extraordinary interpretations regarding their biology. One idea that has persisted in the literature for over forty years is that these trees had extremely short lifespans, on the order of ten years. Such an accelerated lifecycle would require growth rates twenty times higher than modern angiosperm trees (and at least 60 times higher than modern lycopsids). Here, we evaluate the morphology and anatomy of lycopsid trees-including aerenchyma, phloem, leaf base distributions, leaf structure, rootlet anatomy, and the demography of the preserved fossils-with comparison to modern plants with some similarity of overall form, most notably the palms. The environmental context of lycopsid trees also is considered in the light of the vegetation of modern water-saturated substrates. It is concluded that such rapid growth would violate all known physiological mechanisms. One hypothetical mechanism that had been proposed to provide for increased carbon fixation, a unique photosynthetic pathway, could not have been viable in these plants and there is no accounting for the increases in nitrogen and phosphorous uptake that would be necessary to sustain enormous rates of carbon fixation. Of the various aspects of lycopsid anatomy and ecology that might militate against this conclusion that productivity was not high, no line of evidence requires a uniquely rapid growth rate for the arborescent lycopsids and several lines of evidence seem to prohibit it. Thus, we conclude that the lifespans of arborescent lycopsids most likely were measured in centuries rather than years. These trees should not be expected to have been unique outliers with physiological function completely distinct from all other tracheophytes. Furthermore, they require no special consideration in the evaluation of Paleozoic biogeochemical cycling. Finally, the conclusion that lycopsid lifespans were an order of magnitude longer than previous expectations invites reconsideration of many other aspects of their ontogeny, physiology, and structure.

Some ancient rivers have gone extinct, including portions of the great Teays River. Here we investigate the contribution of contemporary and historical drainages to patterns of phylogeographical structure in the spring salamander complex, Gyrinophilus porphyriticus. Eastern North America, USA. Sampling spanned the range of the G. porphyriticus complex, and included representative samples of the cave species of Gyrinophilus as well. Molecular sequence data included the mitochondrial DNA locus cytochrome b and the nuclear locus recombination-activating gene 1 (RAG-1). Time-calibrated phylogenies were inferred, and Bayes-LAGRANGE was used to reconstruct ancestral distributions. Contemporary and historical river influences on patterns of genetic diversity were tested using distance-based redundancy analysis (db-RDA). The G. porphyriticus complex originated prior to the Pleistocene glacial cycles, and historical river systems explained more genetic variation than did contemporary drainages or geographical distance. Patterns of genetic variation suggest that extinct or remodelled palaeodrainages, including the Teays River, played an important role in structuring contemporary patterns of genetic variation. The hydrogeological history of eastern North American drainage basins has been instrumental in structuring patterns of regional biodiversity in freshwater species. Here we show that hydrological remodelling has also left its genetic signature in the semi-aquatic spring salamander complex, G. porphyriticus. Historical drainages accounted for the largest fraction of phylogeographical structure, more so than did contemporary drainages or geographical distance, with spatial and temporal patterns of variation associated with the extinct Teays River.

It has been hypothesized that Martian regolith was incorporated into the melt or, conversely, that the S-enrichment stems from preferential melting of sulfide minerals in the host rock during shock. We present results from an electron microprobe study of EET 79001 including robust measurements of major and trace elements in the shock melt glass (S, Cl, Ni, Co, V, and Sc) and minerals in the host rock (Ni, Co, and V). We find that both S and major element abundances can be reconciled with previous hypotheses of regolith incorporation and/or excess sulfide melt. However, trace element characteristics of the shock melt glass, particularly Ni and Cl abundances relative to S, cannot be explained either by the incorporation of regolith or sulfide minerals. We therefore propose an alternative hypothesis whereby, prior to shock melting, portions of EET 79001 experienced acid-sulfate leaching of the mesostasis, possibly groundmass feldspar, and olivine, producing Al-sulfates that were later incorporated into the shock melt, which then quenched to glass. Such activity in the Martian near-surface is supported by observations from the Mars Exploration Rovers and laboratory experiments. Our preimpact alteration model, accompanied by the preferential survival of olivine and excess melting of feldspar during impact, explains the measured trace element abundances better than either the regolith incorporation or excess sulfide melting hypothesis does.

Many of these estimates of paleo-pCO (sub 2) have relied on the inverse correlation between pCO (sub 2) and stomatal index (SI - the proportion of epidermal cells that are stomata) observed in recent Ginkgo biloba, and therefore depend on the accuracy of this relationship. The SI-pCO (sub 2) relationship in G. biloba has not been well documented, however. Here we present new measurements of SI for leaves of G. biloba that grew under pCO (sub 2) from 290 to 430 ppm. We prepared and imaged all specimens using a consistent procedure and photo-documented each count. As in prior studies, we found a significant inverse relationship between SI and pCO (sub 2) , however, the relationship is more linear, has a shallower slope, and a lower correlation coefficient than previously reported. We examined leaves of G. biloba grown under pCO (sub 2) of 1500 ppm, but found they had highly variable SI and a large proportion of malformed stomata. We also measured stomatal dimensions, stomatal density, and the carbon isotope composition of G. biloba leaves in order to test a mechanistic model for inferring pCO (sub 2) . This model overestimated observed pCO (sub 2) , performing less well than the SI method between 290 and 430 ppm. We used our revised SI-pCO (sub 2) response curve, and new observations of selected fossils, to estimate late Cretaceous and Cenozoic pCO (sub 2) from fossil Ginkgo adiantoides. All but one of the new estimates is below 800 ppm, and together they show little long-term change in pCO (sub 2) or relation to global temperature. The low Paleogene pCO (sub 2) levels indicated by the Ginkgo SI proxy are not consistent with the high pCO (sub 2) inferred by some climate and carbon cycle models. We cannot currently resolve the discrepancy, but greater agreement between proxy data and models may come from a better understanding of the stomatal response of G. biloba to elevated pCO (sub 2) , better counts and measurements of fossil Ginkgo, or models that can simulate greenhouse climates at lower pCO (sub 2) .

Lakela's Mint, Dicerandra immaculata Lakela var. immaculata, is an endangered plant endemic to an approximately 4.8-km long area in Florida, USA. We used an experimental garden and three populations of Lakela's Mint to determine: (1) what is the breeding system (autonomous, asexual, self-fertile, cross-fertile) and are insects necessary for reproduction; (2) which native and nonnative insect species visit flowers and is the frequency of visits to a plant influenced by its height; (3) does the number of flowers visited within a plant by individual insects differ among native and nonnative insect species and due to plant height; and (4) is seed output influenced by plant height? Our results indicate that the breeding system of Lakela's Mint was facultative outcrossing. Insect-pollinated flowers produced more seeds than flowers that reproduced autonomously or asexually. The honey bee Apis mellifera L., a nonnative species, was the most frequent visitor to plants and visited more flowers within plants than native pollinators, but its behavior was not influenced by plant height. Native pollinators such as Bombus impatiens Cresson were attracted more frequently to shorter plants, but visited fewer flowers than on taller plants. Despite having fewer total and pollinated flowers, shorter plants had a higher output of intact seeds than taller plants, which could be due to differences in efficiency between native and nonnative pollinators or other factors. Our results add insight into factors influencing seed output and interactions between pollinators and rare plants.

It is these domesticates, and the agricultural economies based on them, that have formed the lever with which humans have substantially modified the earth's terrestrial ecosystems over the past ten millennia. General explanations for this transition from hunting and gathering to food production economies formulated over the past 40 years have been based on standard evolutionary theory (SET) and employ the assumption of unidirectional adaptation-that environments change and species adapt. Here I compare these proposed SET-based externalist explanations for domestication with a recently formulated alternative developed from niche construction theory (NCT). Archaeological and paleoenvironmental records from two independent centers of domestication in the Americas-eastern North America and the Neotropics of northern South America, are found to support the NCT-based explanatory approach but not the SET explanations, underscoring the limitations of externalist SET approaches and the need for broader conceptualization of the processes that direct evolutionary change in order to gain a better general understanding of initial domestication as well as other major evolutionary transitions.

It illuminates the role of niche-altering activities in bequeathing an ecological inheritance that perpetuates the co-evolutionary relationships leading to domestication, especially as it pertains to traditional ecological knowledge and the transmission of learned behaviors aimed at enhancing returns from local environments. NCT also provides insights into the contexts and mechanisms that promote cooperative interactions in both humans and target species needed to sustain niche-constructing activities, ensuring that these activities produce an ecological inheritance in which domesticates play an increasing role. A NCT perspective contributes to on-going debates in the social sciences over explanatory frameworks for domestication, in particular as they pertain to issues of reciprocal causation, co-evolution, and the role of human intentionality. Reciprocally, domestication provides a model system for evaluating on-going debates in evolutionary biology concerning the impact of niche construction, phenotypic plasticity, extra-genetic inheritance, and developmental bias in shaping the direction and tempo of evolutionary change.

The concept of 'natural' populations is a foundation of modern ecology and conservation, with a large body of theoretical literature using these discrete demographic units to understand population dynamics and prioritize conservation strategies. To date, there are currently no objective methods for empirically delineating large-scale population boundaries using demographic data. 2. We present a novel approach for using large-scale, citizen-science monitoring data to quantify geographic structure in trend and abundance and identify distinct natural populations. We demonstrate this approach by delineating populations of eight passerine species using data collected as part of the North American Breeding Bird Survey. 3. Our approach was able to identify geographic structure in both trend and abundance and to delineate distinct populations for all eight species. An independent validation of three species indicated this demographic variation was reflected in underlying vital rates. 4. Synthesis and applications. Natural populations are biologically based alternatives to the traditional geographically defined units that can improve the ability of researchers and managers to quantify spatial variation in population dynamics. Our analysis of natural population structure in breeding songbirds demonstrates that species can show substantial geographic variation in population attributes and underlying demography. We recommend managers define spatial units using natural populations when setting regional population objectives for both single and multispecies conservation plans.

We applied high-throughput sequencing methods to identify microbial eukaryotes, specifically emphasizing the protistan parasites, in ships' BW collected from vessels calling to the Chesapeake Bay (Virginia and Maryland, USA) from European and Eastern Canadian ports. We utilized tagged-amplicon 454 pyrosequencing with two general primer sets, amplifying either the V4 or V9 domain of the small subunit (SSU) of the ribosomal RNA (rRNA) gene complex, from total DNA extracted from water samples collected from the ballast tanks of bulk cargo vessels. We detected a diverse group of protistan taxa, with some known to contain important parasites in marine systems, including Apicomplexa (unidentified apicomplexans, unidentified gregarines, Cryptosporidium spp.), Dinophyta (Blastodinium spp., Euduboscquella sp., unidentified syndinids, Karlodinium spp., Syndinium spp.), Perkinsea (Parvilucifera sp.), Opisthokonta (Ichthyosporea sp., Pseudoperkinsidae, unidentified ichthyosporeans), and Stramenopiles (Labyrinthulomycetes). Further characterization of groups with parasitic taxa, consisting of phylogenetic analyses for four taxa (Cryptosporidium spp., Parvilucifera spp., Labyrinthulomycetes, and Ichthyosporea), revealed that sequences were obtained from both known and novel lineages. This study demonstrates that high-throughput sequencing is a viable and sensitive method for detecting parasitic protists when present and transported in the ballast water of ships. These data also underscore the potential importance of human-aided dispersal in the biogeography of these microbes and emerging diseases in the world's oceans.

However, strike-slip faults on Enceladus lack these typical lateral offsets and instead are marked by the presence of tailcracks or en echelon cracks. These features are used here to develop the first near-global distribution of strike-slip faults on Enceladus. Strike-slip faults on Enceladus fall into three broad categories: tectonic terrain boundaries, reactivated linear features, and primary strike-slip faults. All three types of strike-slip faults are found predominantly, or within close proximity to, the antipodal cratered terrains on the Saturnian and anti-Saturnian hemispheres. Stress modeling suggests that strike-slip faulting on Enceladus is not controlled by nonsynchronous rotation, as on Europa, suggesting a fundamentally different process driving Enceladus's strike-slip faulting. The motion along strike-slip faults at tectonic terrain boundaries suggests large-scale northward migration of the ice shell on the leading hemisphere of Enceladus, occurring perpendicular to the opening direction of the tiger stripes in the south polar terrain.

The depositional environment varied from a rocky shoreline to the upper continental slope, with sea-level oscillations and tectonic movements causing numerous local unconformities as well as lateral and vertical facies changes. Geohistory and sedimentological analyses show that the area was close to the concurrent sea level at about 15.3 Ma, but at the same time being elevated about 100 m above the present sea level. Although the basin then subsided at least 350 m until around 6 Ma, marine deposition was only recorded after 10.4 Ma. This suggests that the sea level initially dropped faster than the rate of subsidence so that subaerial erosion occurred. The period of subaerial exposure before 10.4 Ma can be attributed to the presence of a NE-trending branch of the Juan Fernandez Ridge below the continental crust at this time, whereas the ensuing subsidence was due to subduction erosion and crustal accommodation in its wake as it migrated south along the South American coastline. The subsequent uplift of at least 250 m can be explained by an acceleration in plate expansion and isostatic rebound of the continental crust after being partially submerged in the upper mantle. The uplift-subsidence-uplift pattern mirrors those recorded around the Nazca Ridge in Peru, as well as in similar basins to the south of Caldera. However, a higher southward migration rate of the Juan Fernandez Ridge against the edge of the South American Plate and less intense uplift-subsidence-uplift cycles are recorded in the latter basins. This can possibly be attributed to oroclinal bending of the ridge due to friction with the overlying continental plate, which diminished the angle of incidence and the intensity of the stress field, but increased the migration velocity of the ridge relative to the coastline.

The 34 fossil-bearing localities identified have yielded a diversity of fossil remains, including vertebrates, mollusks, arthropods, plant fossils, and microorganisms, ranging from the early Paleocene to the late Miocene-?Pliocene (> 20 successive levels). This Cenozoic series includes the base of the Huchpayacu Formation (Fm.; early Paleocene; lacustrine/fluvial environments; charophyte-dominated assemblage), the Pozo Fm. (middle + ?late Eocene; marine then freshwater environments; most diversified biomes), and complete sections for the Chambira Fm. (late Oligocene-late early Miocene; freshwater environments; vertebrate-dominated faunas), the Pebas Fm. (late early to early late Miocene; freshwater environments with an increasing marine influence; excellent fossil record), and Ipururo Fm. (late Miocene-?Pliocene; fully fluvial environments; virtually no fossils preserved). At least 485 fossil species are recognized in the Contamana area ( approximately 250 'plants', approximately 212 animals, and 23 foraminifera). Based on taxonomic lists from each stratigraphic interval, high-level taxonomic diversity remained fairly constant throughout the middle Eocene-Miocene interval (8-12 classes), ordinal diversity fluctuated to a greater degree, and family/species diversity generally declined, with a drastic drop in the early Miocene. The Paleocene-?Pliocene fossil assemblages from Contamana attest at least to four biogeographic histories inherited from (i) Mesozoic Gondwanan times, (ii) the Panamerican realm prior to (iii) the time of South America's Cenozoic "splendid isolation", and (iv) Neotropical ecosystems in the Americas. No direct evidence of any North American terrestrial immigrant has yet been recognized in the Miocene record at Contamana. Abstract Copyright (2016) Elsevier, B.V.

We collected faecal samples from 134 individuals belonging to seven rodent species from the subfamily Sigmodontinae (Cricetidae) over a 2-y period. We conducted seed viability tests for seeds found in faecal samples. We identified seeds from eight plant families (Bromeliaceae, Annonaceae, Brassicaceae, Ericaceae, Melastomatacae, Myrtaceae, Rosaceae, Solanaceae), nine genera and 13 morphospecies. The most abundant seeds belonged to Gaultheria sp. 1 (46% of total) and Miconia sp. 1 (31% of total), while the most viable seeds belonged to Greigia sp. (84% viability) and Guatteria sp. (80% viability). We utilized relative rodent abundance, seed species diversity, seed abundance and seed viability per rodent species to calculate an index of rodent disperser effectiveness, and found that Thomasomys kalinowskii was the most effective disperser, followed by Akodon torques, Calomys sorellus, Thomasomys oreas, Oligoryzomys andinus and Microryzomys minutus. Plant genera dispersed by sigmodontine rodents overlapped more with bird- and terrestrial-mammal-dispersed plants than with bat-dispersed plants. Future neotropical seed dispersal studies should consider small rodents as potential seed-dispersers, especially in tropical habitats where small-seeded, berry-forming shrubs and trees are present.

Co-cycling dissolved oxygen (DO) and pH are difficult to precisely control, as gases used for manipulation influence both parameters. We successfully developed a LabVIEW(TM)-based system capable of monitoring and controlling co-varying DO and pH in raw seawater flow-through aquaria. Using feedback from Oxyguard DO probes and Honeywell ion sensitive field effect transistor Durafet pH sensors, our system controls ratios of nitrogen, oxygen, carbon dioxide, atmospheric air, and CO sub(2)-stripped air within a total gas flow rate through mass flow controllers, to achieve target co-cycling DO and pH values in five treatments. Our system performed well in two long-term experiments investigating effects of diel-cycling hypoxia and pH on eastern oyster (Crassostrea virginica) feeding, growth, fecundity, Perkinsus sp. (Dermo) infection dynamics and immune response. In our 2013 adult oyster experiment, the severe low DO treatment averaged only 0.04 mg L super(-1) higher than the 0.50 mg L super(-1) target, and the moderate hypoxia averaged only 0.05 mg L super(-1) higher than the 1.30 mg L super(-1) target over 48 d of cycles. Mean pH for the hypercapnia plateau was within 0.02 above the 7.00 target. In our 2013 spat experiment, daily minimum DO in the severe and moderate hypoxia treatments were both within 0.06 mg L super(-1) of the 0.50 and 1.3 mg L super(-1) targets, respectively; hypercapnia plateau pH values were within 0.01 of our 7.00 target.

Indication of geographic, ecological and geological barriers affecting the dispersion of species of Ototyphlonemertes (Nemertea, Hoplonemertea) AN - 1776642979; PQ0002775959 AB - Most meiofaunal species are known to have a broad distribution with no apparent barriers to their dispersion. However, different morphological and/or molecular methods supported patterns of diversity and distribution that may be different among taxa while also conflicting within the same group. We accurately assessed the patterns of geographic distribution in actual genetic species of a marine meiofaunal animal model: Ototyphlonemertes. Specimens were collected from several sites around Europe, Northern and Central America, Southern America, Pacific Islands and Asia. We sequenced regions of two mitochondrial and two nuclear genes. Using single-gene, a concatenated data set, multilocus approaches and different DNA taxonomy methods, we disentangled the actual diversity and the spatial structures of haplotypes and tested the possible correlation between genetic diversity and geographic distance. The results show (i) the importance of using several genes to uncover both diversity and highlight phylogeographic relationships among species and that (ii) independent genetic evolutionary entities have a narrower distribution than morphological species. Moreover, (iii) a Mantel test supported a positive correlation between genetic and geographical distance. By sampling from the two sides of Isthmus of Panama, we were additionally able to identify lineage divergence times that are concordant with vicariance mechanisms caused by the geological closure of the seaway across the Isthmus. We therefore propose that in addition to distance, other geological and ecological conditions are also barriers to the dispersion of and gene flow in marine meiofaunal organisms.

While such communities may confer a nutritional benefit to some hosts (termed High Microbial Abundance (HMA) sponges), other sympatric species host only sparse symbiont communities (termed Low Microbial Abundance (LMA) sponges) and obtain a majority of their C and N from local sources. Sponge communities are widespread across large latitudinal gradients, however, and recent evidence suggests that these symbioses may also extend beyond the tropics. We investigated the role that symbionts play in the ecology of sponges from the temperate, hard-bottom reefs of Gray's Reef National Marine Sanctuary by calculating the niche size (as standard ellipse area (SEA sub(c))) and assessing the relative placement of five HMA and four LMA sponge species within bivariate ( delta super(13)C and delta super(15)N) isotopic space. Although photosymbiont abundance was low across most of these species, sponges were widespread across isotopic niche space, implying that microbial metabolism confers an ecological benefit to temperate sponges by expanding host metabolic capability. To examine how these associations vary across a latitudinal gradient, we also compared the relative placement of temperate and tropical conspecifics within isotopic space. Surprisingly, shifts in sponge delta super(13)C and delta super(15)N values between these regions suggest a reduced reliance on symbiont-derived nutrients in temperate sponges compared with their tropical conspecifics. Despite this, symbiotic sponges in temperate systems likely have a competitive advantage, allowing them to grow and compete for space within these habitats.

In nearshore tidal waters, an elevational gradient in aerial exposure during low tide can shape the spatial distributions of benthic marine organisms. The eastern oyster Crassostrea virginica is an ecologically and economically important species that can dominate both subtidal and intertidal habitats along the east coast of the USA. Our goal was to determine whether prevalence and intensity of Perkinsus marinus(the causative agent of Dermo disease) infections vary along intertidal to subtidal gradients during summer. We used (1) field experiments conducted at 4 sites in the Chesapeake Bay and a Virginia coastal bay, (2) a controlled air-exposure experiment, and (3) field surveys from 7 sites ranging from Maine to North Carolina to test for effects of tidal exposure on infection. Results from our field surveys suggested that high intertidal oysters tend to have higher infection prevalence than subtidal oysters, but there was no effect on infection intensity. Field experiments rarely yielded significant effects of tidal exposure on infection prevalence and intensity. Overall, our study shows that exposure to air may not be a strong driver of infection patterns in this host-parasite system.

We reconstructed water table depth using preserved testate amoebae in four stratigraphic peatland cores, supplemented with a literature review to investigate the effects of the Holocene Thermal Maximum (HTM) and Medieval Climate Anomaly (MCA) on surface moisture and long-term apparent carbon accumulation (LARCA) in the regions. A 7320 calendar years before AD 1950 (yrBP) length record registered a wet shift at 4600 yrBP in concert with the HTM and a later post-2550 yrBP shift towards wetter and more stable conditions, possibly related to the Roman Warm Period. During the late-Holocene the three most southern boreal records indicated a lack of droughts during the MCA. Medieval pluvials in boreal Ontario would be consistent with North American precipitation patterns under La Nina conditions. Of the three wet-warm periods identified (HTM, 2550 yrBP, MCA), the 2550 yrBP shift had the most consistent positive influence on LARCA regionally. Although past precipitation was positively correlated with temperature in the region, recent drying may be indicative of a fundamental change in evaporation-precipitation balance.

Based on experience with SHARAD image correction, we propose that ionospheric blurring in MARSIS radargrams may be compensated with a model of smoothly varying quadratic phase errors along the track. This method yields well-focused radargrams for geologic interpretation and allows analysis of the validity range for models used to derive total electron content (TEC) from phase distortion terms in previous MARSIS studies. The quadratic term appears to be a good proxy for TEC at solar zenith angles >65 degrees for MARSIS Band 4 (5 MHz) and >75 degrees for Band 3 (4 MHz). Comparison of MARSIS- and SHARAD-derived TEC values from 2007 to 2014 reveals correlations in seasonal behavior and in the characterization of ionospheric activity due to coronal mass ejections. We also present SHARAD and MARSIS evidence for a persistent region of anomalous radar scattering south of Arsia Mons. These echoes have been previously suggested to arise from refraction of the radar signal by electron density variations. There are no strong signatures, however, in the quadratic image compensation term correlated with the anomalous scattering, suggesting either that electron density variations responsible for refracted signal paths occur primarily in regions offset from the spacecraft track or that these density changes have a minimal impact on the integrated phase distortion of the subspacecraft footprint. We suggest observations and analyses to better constrain the mechanism and timing of such echoes. Abstract Copyright Published 2016.

These changes may increase the ease and frequency with which marine birds and mammals move between the Pacific and Atlantic Ocean basins. Indeed, recent observations of birds and mammals suggest these movements have intensified in recent decades. Reconnection of the Pacific and Atlantic Ocean basins will present both challenges to marine ecosystem conservation and an unprecedented opportunity to examine the ecological and evolutionary consequences of interoceanic faunal exchange in real time. To understand these changes and implement effective conservation of marine ecosystems, we need to further develop modeling efforts to predict the rate of dispersal and consequences of faunal exchange. These predictions can be tested by closely monitoring wildlife dispersal through the Arctic Ocean and using modern methods to explore the ecological and evolutionary consequences of these movements.

Most nodules from the middle of the carbonate dissolution interval contain internal open space, and consist almost entirely of euhedral plate-like jianshuiite crystals, 2-4 mu m in diameter and approximately 0.1-0.5 mu m thick. Backscattered electron images and energy-dispersive X-ray analyses revealed stacks of interleaved Al-rich and Al-poor jianshuiite crystals in some nodules. The crystals in other nodules contain predominantly Mg (with trace K and Al) in addition to Mn and O, making them near "end-member" jianshuiite. Rietveld refinements in space group R3 confirmed the isostructural relationship between jianshuiite and chalcophanite, with Mg occupying the interlayer position above and below the vacant sites in the Mn/O octahedral sheet, and coordinated to 3 octahedral layer O atoms (1.94 Aa) and 3 interlayer water O atoms (2.13 Aa). Final refined occupancy factors suggest that small quantities of Ni and possibly Mn (super 2+) are located on the Mg site. The transient appearance of the Mg-rich birnessite-like phase jianshuiite, probably abiotically produced, must indicate an exceptional transient change in the chemistry of the pore fluids within deep ocean sediments directly following the P/E boundary, possibly as a result of decreasing oxygen levels and pH, followed by a return to pre-event conditions.

Of particular importance is the question of how highly viscous magma can lose sufficient gas in order to erupt effusively as a lava flow. Using an array of methods we study the extreme textural heterogeneity of the Rocche Rosse obsidian flow in Lipari, a 2 km long, 100 m thick, nearly equal 800 year old lava flow, with respect to outgassing and emplacement mechanisms. 2D and 3D vesicle analyses and density measurements are used to classify the lava into four textural types: 'glassy' obsidian ( 40% vesicles), high aspect ratio, 'shear banded' lava (20-40% vesicles) and low aspect ratio, 'frothy' obsidian with 30-60% vesicles. Textural heterogeneity is observed on all scales (m to mu m) and occurs as the result of strongly localised strain. Magnetic fabric, described by oblate and prolate susceptibility ellipsoids, records high and variable degrees of shearing throughout the flow. Total water contents are derived using both thermogravimetry and infrared spectroscopy to quantify primary (magmatic) and secondary (meteoric) water. Glass water contents are between 0.08-0.25 wt.%. Water analysis also reveals an increase in water content from glassy obsidian bands towards 'frothy' bands of 0.06-0.08 wt.%, reflecting preferential vesiculation of higher water bands and an extreme sensitivity of obsidian degassing to water content. We present an outgassing model that reconciles textural, volatile and magnetic data to indicate that obsidian is generated from multiple shear-induced outgassing cycles, whereby vesicular magma outgasses and densifies through bubble collapse and fracture healing to form obsidian, which then re-vesiculates to produce 'dry' vesicular magma. Repetition of this cycle throughout magma ascent results in the low water contents of the Rocche Rosse lavas and the final stage in the degassing cycle determines final lava porosity. Heterogeneities in lava rheology (vesicularity, water content, microlite content, viscosity) play a vital role in the structural evolution of an obsidian flow and overprint flow-scale morphology. Post-emplacement hydration also depends heavily on local strain, whereby connectivity of vesicles as a result of shear deformation governs sample rehydration by meteoric water, a process previously correlated to lava vesicularity alone.

Based on previous observations, it has been hypothesized that ridges develop through a series of evolutionary stages: trough, raised rim trough, double ridge, and complex ridge, with double ridges seemingly the most prevalent. Ridge formation models frequently use an idealized morphology, however the simplification of these structures may in part explain the inadequacy of existing formation mechanisms. Similarly, ridge formation models cannot address the hypothesized genetic relationship of each ridge type. The diversity of ridge morphologies across Europa is not well understood, however previous models of ridge formation are based on detailed, local-scale observations. Thus existing ridge formation models are unable to produce the level of complexity observed by our detailed, regionally extensive mapping campaign. To better characterize ridge morphologies, and evaluate ridge formation mechanisms and evolution, we map ridges across images with resolutions of approximately 250 m/pixel covering approximately 10% of Europa's surface. We present preliminary mapping results from a mosaic located on Europa's antijovian hemisphere, comprised of Galileo images ( approximately 250 m/pixel), which continuously covers latitudes from approximately 70 degrees S to approximately 80N. Initial observations suggest ridge structures are exceedingly diverse. We initially classify ridges into morphological categories of single, double, and complex. We also map troughs, bands, and transitions between features to enable future analysis of ridge evolution. Initial observations of ridge distribution suggest that single ridges become more common than double ridges closer to the poles. Further analysis is necessary to verify if this result is real, an observational bias, or related to low image resolutions.

Nevertheless, the basin has been overlooked as interest in climate change across the P-E boundary has increased in recent years. Here, we present preliminary results from an ongoing investigation of the Paleocene Nacimiento Formation and the early-Eocene San Jose Formation (Cuba Mesa-Regina Members) in the SJB. The long-term goals of this study are to (1) refine the chronostratigraphy of the P-E boundary and determine whether records of early-Eocene hyperthermals are preserved, (2) describe climatic conditions and their impact on fluvial sedimentation, and (3) compare data collected from the SJB with published datasets from other Laramide basins. Preliminary biostratigraphic data suggest a late-Paleocene age for the upper Nacimiento Formation and an early-Eocene age for the upper-most Cuba Mesa Member. Variations in carbon isotope ratios of lignitic wood fragments from the Cuba Mesa Member are indicative of carbon isotope excursions, however, additional data are needed to determine if records of the Paleocene-Eocene Thermal Maximum (PETM) or other hyperthermal events are preserved. There is a transition from isolated fluvial channel deposits bounded by drab mudstones in the Nacimiento Formation to laterally-continuous, amalgamated fluvial channel complexes in the Cuba Mesa Member. Changes in channel deposits are consistent with an increase in deposition and discharge rates into the Eocene, while associated changes in mudstone floodplain deposits from drab to increasingly variegated (grey-purple-red) mudstones are consistent with improved soil drainage. These changes in fluvial deposits are similar to those associated with the P-E boundary in Laramide basins further to the north. Overall, these initial results from the SJB suggest that continued study of the sedimentological, biological, and geochemical records in the area should provide useful data to further research of the P-E boundary in the Southern Cordillera of North America.

While all major continents once harbored giant mammals such as mammoth, woolly rhinoceros, mastodon, camels, llamas, and/or horses, few of these extremely large-bodied species remain, and they are mostly confined to the African continent. This decline mirrors the movement of modern humans across the globe and has intensified as human populations increased and expanded over the late Quaternary. Yet, the consequences of this prolonged loss of megafauna biodiversity have been understudied. Here, we quantify a number of important macroecological patterns of mammals over time to investigate how the loss of megafauna has influenced the shape and functioning of ancient and modern ecosystems and what modern ecosystems will likely look like in the future. Specifically, we focus on Africa, Eurasia and the Americas. Using a late Quaternary database (MOM v6.0) of mammals, we quantify the shape of the body size distribution, energy and biomass flow, and species diversity patterns at 6 time periods: 100ka, 20ka, 10ka, 0.3ka, modern and 0.2 ka years in the future. These time periods correspond to the dispersal of modern humans from Africa across the globe, before and after their entry into the Americas, European migration, and 200 years post modern. We assume that all mammals currently endangered become extinct. Our results show an increasing homogenization of ecosystems; although the continents experienced megafauna biodiversity losses of varying intensity at different times, future macroecologial patterns will be similar on each. Because megafauna have a disproportionate influence on ecosystem structure and function, ecological interactions between species, and even biogeochemical cycling, our results strongly suggest that continued "trophic downgrading" may lead to unanticipated effects that influence virtually all aspects of ecosystems.

The early-middle Turonian Tanzanian record reveals a prolonged period of species stasis with essentially no changes in species relative abundance, no species extinctions, and no evolutionary first occurrences for both calcareous plankton groups until the late middle Turonian. This is followed by two species turnover events in the late Turonian that have not been well documented previously. The older of these turnovers occurs at the top of the mid-Turonian Helvetoglobotruncana helvetica Zone, where last occurrences of four planktonic foraminiferal species are immediately followed, within several meters, by first occurrences of five foraminiferal species and an increase in the abundance of dwarfed planktonic forms. Changes in the calcareous nannofossil assemblages are less profound and marked by the extinction of one calcareous nannofossil species and an abrupt but temporary spike in the abundance of another species. There are no obvious changes in lithology, bulk sediment geochemistry, or stable isotope values across this first turnover event. The second species turnover occurs within the late Turonian middle Marginotruncana schneegansi Zone and is marked by extinction of three calcareous nannofossil species followed by first appearances of four calcareous nannofossil species. Corresponding with the nannofossil first occurrences are a dramatic increase in the relative abundance of biserial taxa, first occurrences of two planktic foraminifer species, a strong diagenetic shift causing calcareous infilling of all foraminiferal tests in overlying samples, and an increase in sediment grain size. Comparison between the TDP planktonic foraminiferal species distributions and those observed in Turonian core samples from Ocean Drilling Project Hole 762C (Exmouth Plateau, subtropical southeast Indian Ocean) reveals significant differences, including: (1) no evidence at Site 762 for evolutionary stasis during the early-middle Turonian; (2) several marginotruncanid planktonic foraminifera have older stratigraphic ranges at Site 762; and (3) the species changes associated with the turnover events in Tanzania are much less significant at Site 762. These differences are attributed to factors related to the different mesotrophic and oligotrophic environmental settings of the clastic margin vs. pelagic carbonate sequences. Taxonomic study and biostratigraphic comparisons between these sites result in an improved integrated biostratigraphic scheme that improves the temporal resolution for global correlation of calcareous nannofossil and planktonic foraminiferal bioevents.

Our analysis of the structures within Dione's wispy terrains reveals tectonic features identified as scarps, twin scarps (likely graben), and troughs. Along with being less tectonically resurfaced than Enceladus, it is interesting that Dione's tectonic structures are morphologically limited when compared with the wide diversity of tectonic structures on Enceladus' surface. Using SatStressGUI, we model global-scale stress mechanisms including nonsynchronous rotation and diurnal tidal stresses at Dione's surface to identify likely stress mechanisms that may have resulted in the fracture pattern across Dione's wispy terrains. We present results from global stress modeling which suggests that a nonsynchronous rotation induced stress field may have been able to produce the observed fracture patterns in the wispy terrains. Nonsynchronous rotation has been suggested to have occurred, or is occurring on Europa and Enceladus, which infers the presence of global subsurface oceans. If the fracture pattern on Dione is attributed to nonsynchronous rotation, it would suggest that Dione has or had a global subsurface ocean.

In modern coastal settings, foraminifera act as ecological barometers in their responses to different conditions such as food availability, oxygen, salinity, and trace metals. A detailed survey of foraminiferal populations was undertaken in the Mission-Aransas National Estuarine Research Reserve (MANERR), Texas, close to the time of its establishment in 2006. The purpose of the study was to gauge the overall status of populations and provide baseline data for future comparison. Located in an arid climate, the south Texas Gulf Coast is a prime example of a varying and often harsh environment. Biota face extremes in temperature and precipitation along with multiple anthropogenic stressors. Despite these rigors, living foraminifera are flourishing in the MANERR. This paper discusses the results from Mission, Mesquite, and Copano Bays, secondary and tertiary bays in the reserve. Populations are robust in each bay, with highest numbers corresponding to areas of greater circulation. Ubiquitous framboidal pyrite in the sediment and in shells does suggest that foraminifera are frequently subject to low oxygen conditions. Elemental analysis of shell composition was prompted by presence of sulfur in sediments and by yellow tests, and showed presence of barium, strontium, and iron. Healthy living numbers, tolerance of low oxygen conditions, and the ability to cycle elements emphasize the resilience of foraminifera in taxing environments and their integral position as lower trophic level community members.

Here we show the spatiotemporal dynamics of species diversity in the Western Pacific through the Cenozoic, focusing on the tropical Indo-Australian Archipelago (IAA) biodiversity hotspot. We analyzed well-preserved fossil ostracodes from the tropical Western Pacific and combined their diversity data with other published data from the region to reconstruct Cenozoic dynamics of species diversity in the tropical- and northwestern Pacific Ocean. We fit generalized additive models to test for differences in richness over time and across geographic regions while accounting for sample size variation among samples. Low-, mid- and high-latitude regions all show a similar diversity trajectory: diversity is low in the Eocene and Oligocene, increases from the Early Miocene to the Plio-Pleistocene but then declines to the present day. Latitudinal diversity patterns are relatively flat and rarely show the typical decline from tropics to high-latitude. Modern-level high biodiversity in the tropical IAA and the northwestern Pacific Ocean was established during the Pliocene. The modest diversity decline from the Plio-Pleistocene to the present day may be attributable to large amplitude glacial-interglacial climate and sea-level changes. The weak and irregular (i.e., inverse, mid-latitude-peaked, or mid-latitude-depressed) latitudinal species diversity gradients are unexpected, because the northwestern Atlantic Ocean displays a standard tropical-high and temperate-low diversity pattern throughout the Cenozoic. In addition, ostracodes are known to show standard latitudinal diversity gradients in the North Atlantic. These differences suggest an important role for regional factors (e.g., plate tectonics and temporal geomorphological dynamics), in shaping the biodiversity of the Western Pacific.

The fan systems, centered at about 20.5 degrees S, 69.4 degrees W are active at about decadal frequency. Individual flows extend 20-30 km across the basin, with individual flows averaging about 0.5 meters deep but nearly equal 1 km across. Individual deposits are typically 5-25 cm thick with a matrix averaging roughly 15% expandable clay, 40% silt, and 45% sand, mixed with variable amounts of fine gravel. Near the fan apex flows are partly channelized, but downstream the flows occur as shallow, braided flows with extensive overbank deposits. The mudflows also transport a small proportion of coarse gravel to boulders, deposited as bars and one- or two-boulder wide levees. Some of the boulders are rip-up clasts from earlier events. The coarse component is primarily transporting by rolling across the smooth fan surface. The mud deposits are susceptible to wind erosion, so that older flows become covered by a dark armor of granules to pebbles. Individual flows only partially follow the path of earlier flows, with frequent creation and abandonment of individual channels. The thick fan deposits are therefore composed of thousands of thin, interlaced mud deposits with granule or pebble deflation lags and scattered boulders and boulder bars associated with channels.

In our study, we use ostracode microfossils as a model system for evaluating modern ecosystem diversity and assessing the impacts of climate change on large-scale biodiversity pattern during the geologic past. Based on our modern equator-to-pole ostracode dataset, which covers 558 sites and >150,000 specimens in the western North Atlantic and Arctic Oceans, we observed a diversity gradient with a maximum in tropics and decreasing diversity towards the Arctic. We also compared the modern diversity patterns to those during past interglacial periods in the Pliocene (5.33-2.58 Ma) and the Pleistocene Marine Isotope Stage 5 (125,000 yrs ago), using fossil ostracode assemblages. Results suggest that Pliocene and Pleistocene climate changes affected large-scale biodiversity patterns in the North Atlantic Ocean, including geographic shifts in the location of diversity maxima.

Volcanic activity is responsible for this relatively new surface. The timing, size, and distribution of recent volcanic deposits have implications for which of the endmember models, catastrophic or equilibrium resurfacing, dominated this activity on Venus. Here we analyze the extent of parabolic impact crater ejecta, interpreted as some of the youngest deposits on Venus, and their stratigraphic relationships with different terrains, such as the tesserae and low-lying plains, to search for recent volcanic activity. Measurements of the backscatter coefficient from Magellan SAR left-look data are used to determine if there is a non-uniform distribution of crater ejecta superposed on the ancient highly deformed tesserae and low-lying plains materials. At Sudenitsa Tesserae, one of our study regions, several areas of low radar backscatter are identified in tessera materials, while no areas of low backscatter are found in the adjacent low-lying plains. The most plausible source of low backscatter material is the parabolic ejecta from relatively recent impact events. There is no obvious source crater for the low backscatter material at Sudenitsa. However, the location of Sudenitsa Tesserae on the northwestern border of the Beta-Atla-Themis (BAT) region, with 2-4 times the number of volcanic features observed on the rest of the planet, may explain the absence of a source crater. For instance, recent north-trending lava flows sourced from Polik-mana Mons, to the south of Sudenitsa Tesserae, may have resurfaced the source crater and some/all of the parabolic ejecta. The presence of the low backscatter material in Sudenitsa Tesserae and a missing source crater suggests that the parent impact crater was recently resurfaced (likely less than 80 Ma). A low-eruption rate lava flow sourced from the BAT region is capable of burying the source crater and some or all of the parabolic ejecta on the low-lying plains, consistent with equilibrium resurfacing models.

Planktonic foraminifera at Tanzania Drilling Project (TDP) Site 39 are diverse and the occurrences of Tethyan marker species enable application of the tropical biozonation. The topmost 70.18 m of the section are assigned to the Dicarinella asymetrica Zone, while the underlying sediments belong to the Dicarinella concavata Zone. In addition, TDP 39 is proposed as reference section for the Coniacian/Santonian boundary in the Indian Ocean with the boundary placed at the lowest occurrence of Globotruncana linneiana in agreement with the sequence of events defined at the GSSP stratotype section in Spain. The sedimentary record at TDP 39 was deposited in an outer shelf to upper slope setting dominated by calcareous clayey siltstones and mudstones and, thus, provides a unique opportunity to document the planktonic foraminiferal evolution in a subtropical marginal sea environment. Specifically, the Coniacian-Santonian interval represents a key-period in the evolutionary history of planktonic foraminifera during which deep dwelling taxa underwent a major radiation (originations outnumbered extinctions) that has been related to a series of climatic and oceanographic changes. Combined documentation of lithological and geochemical data from TDP 39 reveal a paleoceanographic history influenced first by a high transfer of continental-derived nutrients to surface waters in the D. concavata Zone that shifts to higher carbonate production and reduced surface water primary productivity in the overlying D. asymetrica Zone. Planktonic foraminiferal assemblage changes mirror the depositional and geochemical trends and indicate a progressive change from a more eutrophic to a more oligotrophic regime associated with both a well-defined mixed layer and a stable thermocline. At the local scale, this paleoceanographic scenario is consistent with the deepening of coastal Tanzania in response to the widespread, Late Cretaceous marine transgression registered on the passive margin along southeastern Tanzania after the separation of Madagascar from India at approximately 93 Ma. Epicontinental invasion of oligotrophic waters during the high sea-level stand may have provided increased opportunities for planktonic foraminifera to exploit new ecological niches. Because the tectonic evolution and sea-level rise along the East Africa continental margin is superimposed on the global long-term sea-level high documented for the Coniacian-Campanian time interval, we hypothesize that the epicontinental invasion of blue water may have favoured the evolution of new lineages within the deep-dwelling taxa.

J. Sinclair in 1905. Since its discovery, it has been transferred from one primitive peccary genus to another (Thinohyus, Bothrolabis, Perchoerus), without a careful examination of the excellent fossils. It is not referable to Thinohyus from the John Day beds, since it has a much more advanced skull, with a narrow rostrum with shallow facial vacuities, not the convex conical rostrum found in Thinohyus and more primitive peccaries. It was assigned to that genus only because its teeth are the same size and it came from the same beds, but this makes Thinohyus into a wastebasket taxon. Careful re-examination of the skull shows that it has the diagnostic plesiochoanal fossa found only in the newly recognized Subfamily Hesperhyinae, as well as other derived characters of that group. It is a relatively primitive member of that group (in the same trichotomy as Stuckyhyus siouxensis and Floridachoerus olseni) consistent with its stratigraphic position in the late Arikareean. It belongs in a new genus, which will be published elsewhere. This now makes eight genera (five of them new since 2015) and eight species (two of them new since 2015) described in this large and diverse but previously unrecognized subfamily. None of these taxa (except for Hesperhys) was recognized in any of the existing paleobiological databases (MIOMAP, PBDB), or some of them are mentioned but misassigned. Such hidden diversity, especially in poorly studied groups with lots of undescribed specimens, reveals a level of taxonomic diversity that is underestimated or misassigned in paleobiological databases, and seriously compromises their credibility.

Their evolutionary history has been influenced by paleoceanographic, climatic, and extra-terrestrial events and has also resulted from random walks that are unassociated with any discernable extrinsic cause. The Cenomanian is an intriguing time in which global warmth may have led to increased planktic foraminiferal speciation. However, evolutionary relationships between various taxa are tangled in the literature, impeding further understanding. A study of the genus Rotalipora (focusing on cushmani, praemontsalvensis, and montsalvensis) was conducted on well preserved samples from Ocean Drilling Program Site 1050 (Blake Nose, subtropical North Atlantic Ocean). Spiral and edge view orientations were imaged and digitized to obtain a suite of size and size-independent measurements across the stratigraphic ranges of each species. Primary type material was included in the study for comparison, as were other published images from the literature. The rotaliporid morphospace is defined by both a mixture of qualitative descriptive terms used in Cretaceous planktic foraminiferal taxonomy (e.g., accessory aperture position and types of sutures, 11 in total) as well as 14 quantitative parameters constructed by approximately 40 measures. With these data, it is possible to characterize the population variability and evolutionary transition from the ancestral to descendent morphologies. A variety of statistical methodologies are employed to define the morphospace including hierarchical cluster and principle components analyses. Study of the Rotalipora lineage will lead to a better understanding of its position within the greater Cenomanian planktic foraminiferal morphospace and determination whether the ancestor-descendent transitions were marked by morphologic discontinuities or gradual shifts in population morphospace.

Species concepts for this group are based on shell morphology and growth characteristics. In many cases, these concepts need further refinement using modern morphometric methods. The Late Cretaceous planispiral genus Globigerinelloides is one group that requires revision as there has been considerable confusion in taxonomic concepts used by different workers and ancestral-descendent relationships are generally poorly known. To better characterize taxonomic distinctions and the phylogenetic history of this taxon we picked all morphotypes of Globigerinelloides present in late Campanian-Maastrichtian Deep Sea Drilling Project (DSDP) and Ocean Drilling Program (ODP) sediment samples that were drilled at both high and low latitude sites in the Atlantic and Pacific oceans (sites: 327, 463, 465, 511, 690, 1049 and 1050). Species identified include G. asper, multispinus, G. prairiehillensis, G. messinae, G. subcarinatus, G. volutus, G. alvarezi, G. impensus and G. ultramicrus. Lower, middle and upper levels of the cored intervals were picked at each site to determine whether the species shows morphological stasis or gradual morphologic shifts within their evolutionary ranges. Using a scanning electron microscope (SEM), side and edge images were taken for five individuals per species group from each sample level and for the holotype and paratypes of each species. High-resolution, cross-sectional X-ray images were used to obtain measurements of the ontogenetic changes in chamber cross-sectional areas. The resulting size and size-independent morphological and qualitative observations (e.g. uni- versus bi-apertural) for this genus were then analyzed using multivariate statistical methods. Completion of these morphometric analyses will enable justification for taxonomic revision of the Late Cretaceous planispiral taxa and improved understanding of the phylogenetic history of this biostratigraphically important but underutilized taxonomic group.

Distinguishing between these possibilities has been limited by a dearth of late Ediacaran fossil localities that are well-constrained temporally and that contain overlapping assemblages. For example, though the late Ediacaran Nama Assemblage in Namibia is thought to be correlative to the Gaojiashan Assemblage in China, each of these assemblages preserves a markedly different biota. Here, we report new fossils from latest Ediacaran strata within the lower Member of the Wood Canyon Formation in Death Valley that establish a link between latest Ediacaran assemblages globally. This newly described assemblage of fossils includes three-dimensional preservation of soft-bodied Erniettomorphs, similar to those in the Nama Assemblage, as well as cast and molds and secondary pyritization of a variety of tubular fossils, similar to those in the Gaojiashan Assemblage. This is the first report of many of these fossils occurring in the same stratigraphic section, providing a biostratigraphic link between latest Ediacaran assemblages found in Namibia, South China, Siberia, Brazil, and Paraguay. Therefore, the Wood Canyon Assemblage supports the theory that a distinct latest Ediacaran faunal assemblage is the result of true biotic turnover during the end of the Ediacaran Period, prior to the Precambrian-Cambrian boundary.

N1 - Last updated - 2017-01-24 ER - TY - JOUR T1 - A tale of two ridges; relief inversion on distal alluvial fans in the Pampa del Tamarugal region of the Atacama Desert, Chile AN - 1861111911; 787345-68 AB - Alluvial fans of the Chilean Atacama Desert record a spectrum of flow events, from fluvial floods to sheet-like mudflows, which generate a complex network of active and abandoned channel segments. On the distal bajada, wind scour has resulted in landscape inversion of some channel segments. We characterize two inverted channel segments near Salar de Llamara as examples of the various factors producing similar-appearing ridges. Although both ridges mark former flow paths that incised into playa deposits and are in close proximity (within 150 m), these inverted channels differ markedly in traverse shape, erosion-resistant agent, grain size and composition. These examples highlight the challenges in reconstructing flow properties and development sequence solely from remotely sensed data, as is done for martian inverted channels. Ridge 1 is a 0.5 km long segment, up to 3 m wide with a surface that is flat to concave. Discontinuous, thin gypsum plates (<15 cm) cap the surface and precipitated in standing water. An excavated trench on the eastern end reveals four indurated sandy layers (0.10-0.25 m thick) with varying amounts of mud associated with an aggrading fluvial system, and two lower layers of playa deposits that are regionally correlated with other outcrops. The vertical profile records episodic wet periods, as evidenced by root fragments and iron-stained plant molds, and dry intervals marked by salt hardpans at some layer boundaries. Short (<20 m) spurs suggests the ridge was part of a contributory drainage network. Ridge 2 is an approximately 2 km long, gravel capped inverted channel segment with a pointed to rounded (up to 2 m wide) crest. The coarsest grain size (1-2 cm) are concentrated on the ridge crest, consistent with fluvial transport along this corridor. Threshold flows to transport the pebbles across the 0.5% regional slope would require approximately 30 cm deep flows with approximately 1 m/s average velocity. The ridge surface is generally unconsolidated, although there are isolated patches that are weakly indurated by efflorescent salt. Most ridge slopes are armored by a terrain-conformal halite crust that may also retard landform degradation. Beneath the gravel monolayer is a 0.5 m thick, massive, uncemented layer of fine sand with floating pebbles. Deflation of this fluvial deposit generated the uppermost gravel pavement that armors the ridge.

How do paleontologists and collections professionals meet these challenges? How do we engage with natural history data programs (e.g. iDigBio and GBIF)? How do we implement data initiatives and strategies (e.g. Darwin Core)? The solution to these questions can easily become overly complex. In the Smithsonian National Museum of Natural History Department of Paleobiology we have established guidelines for focusing our approach in order to minimize the possible complexities. Our approach has included efforts to evaluate our collections database (EMu), build digitization workflows, and assess data management practices. While maintaining the guidelines we have established, we have also considered the growth of the global collections community, looking at what standards exist or are lacking, how data are structured, and what the data needs are in the biodiversity informatics field. In this discussion we will share our approach and guidelines and hope to invite collaboration for further research and evaluation with our peers.

The main goal of the project was to document and research Panama's Neogene biodiversity, especially in regard to the Great American Biotic Interchange, while promoting science education and outreach for the next generation of scientists. During the second year of the PCP PIRE project, an internship program was established to allow a mixture of undergraduate, post-baccalaureate, and graduate students to develop their fieldwork skills in an international setting. Initially, internships lasted 3 or 4 months for groups of up to four interns. During the last year of the project, the internship program became more focused, allowing two interns to stay in Panama for a 10 month duration. Forty-one field interns lived in Panama in total over the course of the project. While the primary focus of the internship was to survey canal excavation sites for fossil identification and extraction, the interns had unique opportunities to utilize and hone extensive geoscience skills. The interns learned exploration and reconnaissance techniques used to discover new paleontological resources at various locations throughout the country of Panama. They also learned to recognize and appreciate the urgency for intensive sedimentology and stratigraphy projects to document newly excavated hillsides ahead of the rapid growth of tropical vegetation. Through educational outreach programs in the community, the interns were able to emphasize and demonstrate the importance of field experiences for learning about and appreciating the environment, and they were also able to participate as field leaders in a ten day workshop for earth science educators from the United States.

It is known from sections in the Uwekahuna Bluff and underground at Tree Molds, plus numerous exposures on Kilauea's south flank. Correlations between sections depend heavily on locating a marker horizon that contains shards of a distinctive high-TiO (sub 2) , high-K (sub 2) O glass (the K-2 layer). On a plot of TiO (sub 2) vs. MgO for samples from the 1959 Kilauea Iki lava lake, glasses from the high-TiO (sub 2) layer lie at the low end of the olivine-controlled samples, at 6.5-7.0% MgO, falling in the gap between the olivine-controlled compositions and various internal differentiates observed in the lava lake. We infer that the parental magma of the high-TiO (sub 2) layer resembled the 1959 compositions. We have evaluated Kulanaokuaiki glass compositions using plots of CaO vs. MgO (to determine the extent of crystallization of the melts) and TiO (sub 2) vs. MgO (to establish whether high-TiO (sub 2) parental melts exist in other tephra layers). Glasses with possible parental compositions (with high CaO and TiO (sub 2) plus high K (sub 2) O levels) are present in four layers immediately above the samples that contain the high-TiO (sub 2) , high-K (sub 2) O glass in the Uwekahuna Bluff section. Similar stratigraphy is observed in the Tree Molds section, where the K-2 horizon is overlain by a single layer containing some glasses like those of the 1959 lavas. The MgO contents of the potential parent melts are 9.2-10.0% MgO, similar to the most magnesian melts erupted in 1959. The lack of intermediate compositions suggests melt was stored at two levels, with the high-TiO (sub 2) , high-K (sub 2) O source body relatively shallow, and the parental liquids having come from greater depth. The crystallization behavior of Kilauea basalts constrains the composition of the K-2 marker horizon in two ways. First, at MgO approximately 7.0%, the melts shift from 1-phase to 3-phase crystallization, and the increase in heat of crystallization per degree of cooling for the 3-phase assemblage tends to inhibit further evolution of melt compositions at depth. Second, densities of such melts lie near a minimum in the density curve, which may facilitate segregation of these melts into discrete layers or separate bodies consisting almost entirely of minimum-density melts. Both processes acted to produce the K-2 marker horizon.

The third of these five deposits, K-3, consists mostly of scoria lapilli but this unit is also associated with lithic blocks, the largest of which have diameters greater than the thickness of associated K-3 scoria deposits. Much of the K-3 scoria has been eroded away, leaving blocks and lithic lapilli as lag clasts on the pre-K-3 surface. A new strategy was required to quantify the distribution of these widely scattered clasts. Don established a 110-node network defining collection sites separated by approximately 700 m. He then adopted an 18-minute search routine that normalized collection durations and provided ample time to locate the scattered lag lithics. Visiting each of these 110 nodes, he collected the ten largest clasts, photographed them in the field, and returned all 1100 of them to HVO for future study. The isopleth map resulting from this work shows that dense, 8-12 cm blocks were dispersed 9-10 km southeastward from the interpreted summit vent, an anomalous direction at a high angle to prevailing northeast trade winds. In addition, largest clast diameters decrease toward the southeast, indicating that these clasts were not dispersed ballistically. These findings led to the interpretation that these lithic clasts were entrained in a powerful jet, likely powered by steam or CO (sub 2) , that carried them to jet stream altitudes (4-17 km), where prevailing winds of 20-50 m/s deflected their rise and fall toward the southeast. These accomplishments are good examples of how Don's field-geology expertise, plus a large measure of hard work, has led to new volcanological understandings. Specifically, it is now realized that Kilauea can erupt far more energetically than anyone dared to imagine.

Based on previous observations, it has been hypothesized that ridges develop through a series of evolutionary stages: trough, raised rim trough, double ridge, and complex ridge, with double ridges seemingly the most prevalent. Ridge formation models frequently use an idealized morphology, however the simplification of these structures may in part explain the inadequacy of existing formation mechanisms. Similarly, ridge formation models cannot address the hypothesized genetic relationship of each ridge type. The diversity of ridge morphologies across Europa is not well understood, however previous models of ridge formation are based on detailed, local-scale observations. Thus existing ridge formation models are unable to produce the level of complexity observed by our detailed, regionally extensive mapping campaign. To better characterize ridge morphologies, and evaluate ridge formation mechanisms and evolution, we map ridges across images with resolutions of approximately 250 m/pixel covering approximately 10% of Europa's surface. We present preliminary mapping results from a mosaic located on Europa's antijovian hemisphere, comprised of Galileo images ( approximately 250 m/pixel), which continuously covers latitudes from approximately 70 degrees S to approximately 80N. Initial observations suggest ridge structures are exceedingly diverse. We initially classify ridges into morphological categories of single, double, and complex. We also map troughs, bands, and transitions between features to enable future analysis of ridge evolution. Initial observations of ridge distribution suggest that single ridges become more common than double ridges closer to the poles. Further analysis is necessary to verify if this result is real, an observational bias, or related to low image resolutions.

The well-documented paleontological record from the Kaiparowits Formation (Late Cretaceous, 76.6-74.5 Ma) of the Grand Staircase-Escalante National Monument in south-central Utah has significantly enhanced our understanding of ecology and biogeography of Campanian ecosystems. The associations between plants and their insect herbivores, which together constitute about half of all described extant species, is unknown from the Kaiparowits Formation. A preliminary assessment of the diversity and richness of insect damaged fossil leaves of Kaiparowits flora has yielded preliminary evidence for a wide diversity of insect herbivores. Eight functional feeding groups were recorded in the 912 plant fossil specimens, which include hole feeding, surface feeding, skeletonization, leaf mining, oviposition, piercing and sucking, galling, and seed predation. A large proportion of the fossil leaves (48.4%) were herbivorized by insects and specimens often displayed multiple damage types. Analysis of plant-insect associations is vital to the ongoing paleoecological reconstruction of the Kaiparowits Formation.

These hydrogen-bearing areas have been interpreted to contain exogenic material implanted by impacts onto Vesta's surface, the exogenic material resembles CM chondrite meteorites. Vesta is a nearly intact relict planetesimal that formed within a few million years of the formation of the first solids in our Solar System and before the formation of Earth. The howardite, eucrite, and diogenite (HED) meteorite clan likely originates from the asteroid 4 Vesta. Of the HED clan, the howardites (breccias composed of clasts with diverse origins) are the best meteorite analogs for most of Vesta's surface. In one such howardite breccia-a meteorite found in the Grosvenor Mountains (GRO) in Antarctica, GRO 95574-we found an olivine-rich solidified melt droplet that in mineralogy and chemistry does not resemble the impact melts typically found in howardites. As determined by EMP and SIMS, the elemental and oxygen-three isotope signaturesaof the olivine microphenocrysts in this melt droplet are consistent with this clast forming from a melted primitive chondritic meteorite, most likely a CM chondrite. The Fe-rich composition of the glass in this melt droplet and its bulk silicate composition are also consistent with it forming from whole-rock impact melting of a CM chondrite rather than this droplet being an isolated chondrule. Unmelted CM chondrites contain 6.5-12.5 wt. % water equivalent hydrogen primarily as mineralogically bound OH in phyllosilicates; accordingly, if this droplet formed from a CM chondrite most of this water was degassed because no water was detected in our micro-Raman spectroscopic analyses of the glass in this clast (detection limit of 2 wt. % H2O for these samples). The identification of this CM chondrite impact melt droplet in a vestan regolith analog complements findings by the Dawn spacecraft mission CM chondrite-like materials were emplaced into the specific areas on the surface of Vesta by impacts.

We present an overview and recent results from our work on pink, blue and chameleon diamonds. aBoron causes the blue color of the Hope Diamond and other type IIb diamonds, but scarcity, high value, and the low concentration of B has inhibited B analyses of natural IIb diamonds. We used FTIR and ToF-SIMS to measure concentrations and distributions of B in the Hope and other blue diamonds. ToF-SIMS analyses gave spot B concentrations as high as 8.4 � 1.1 ppm for the Hope Diamond to less than 0.08 ppm in other blue diamonds and revealed strong zoning of B in some diamonds, which was confirmed by mapping using synchrotron FTIR.aBoron is also responsible for the phosphorescence emissions of IIb diamonds, at 660 nm and 500 nm; the emissions are likely caused by donor-acceptor pair recombination processes involving B and other defects. aApproximately 50 type I natural pink diamonds were compared using UV-Vis, FTIR, and CL spectroscopies. All stones exhibit pink color zoning, nearly equal 1mu m thick [111] lamellae, in otherwise colorless diamond.aThe pink diamonds fall into two groups: 1) those from Argyle in Australia and Santa Elena in Venezuela, and 2) those from other localities. TEM imaging from FIB sections revealed that twinning is the likely mechanism by which plastic deformation is accommodated for the pink diamonds. The deformation creates new centers, including the one responsible for the pink color, which remains unidentified. The differences in the plastic deformation features for the two groups might correlate to the particular geologic conditions under which the diamonds formed.aFluorescence and thermoluminescence experiments on natural chameleon diamonds reveal that an emission band, peaking near 556nm, may be stimulated via a number of different mechanisms. We discuss the implications of our observations for the electronic structure of the 556nm-fluorescing defect center, and the connections to the unidentified color center responsible for chameleon color changes.

We have initiated a study of some specific sand dunes on and adjacent to the southern margin of the main dune mass at GSDNPP. A handheld Trimble GeoXH unit was used to document both the crest and the basal margins of several dunes in an effort to track movement of the crest of the dunes, as well as to constrain the volume of sand involved in any detected movement of the dunes. The GeoXH makes use of both US Global Positioning System (GPS) satellites and other international satellites available through the Global Navigation Satellite System (GNSS) to record positional information that, after post-processing (which is a free service), locations are produced with a horizontal precision where >96% of the points are located to better than 15 cm (6 inches). This accuracy is sufficient to monitor changes to the dunes on a horizontal scale >0.5 m. GeoXH surveys were conducted at GSDNPP in June of 2015 and 2016, which provides an early assessment of the yearly movement of some of the dunes. Initial results indicate that the movement of the dunes at GSDNPP may be less systematic than had been previously anticipated. One dune on the sloping southern side of the main dune complex appears to show a rather complex motion of the dune crest, with portions of the dune crest moving >2 m to the east during the same time interval when other crest portions moved up to 1 m to the west. Vertical precision of the location data is less well constrained than is the horizontal precision, but it is still sufficient to allow a determination of the volume of mobile sand associated with each monitored dune. Future efforts will relate GeoXH results to previous survey-grade differential GPS measurements of other dunes along the southern margin of the GSDNPP dune field, as well as to measurements of sand dunes on Mars obtained from data derived from the High Resolution Imaging Science Experiment (HiRISE).

To this end, paleontologists have linked lineage origination and extinction with traits such as body size and geographic range. One evolutionary driver not yet considered is the extent of sexual selection-selection that specifically influences mating outcomes-operating within species. In extant species, sexual selection may cause reproductive isolation and, hence, promote speciation. Theoretical models and experimental studies indicate that strong sexual selection can increase extinction risk from the demographic drag caused by investment in the costly structures that commonly evolve under sexual section (e.g., weapons or large body size). However, it is often impossible to study actual extinction and origination in living fauna and therefore this issue will remain largely untested without the inclusion of fossil data. Here we present an analysis of species-level origination and extinction of cytheroid ostracodes from a composite reference section spanning 15 million years of the Late Cretaceous (Santonian to early Maastrichtian). Cytheroids possess sexually dimorphic shells, with males relatively more elongate and often absolutely larger than females. The degree of sexual dimorphism is thought to reflect the intensity of sexual selection. We used mixture modeling to identify sex clusters in biometric samples. From these, we computed sexual dimorphism in body size (difference in log area between the sexes) and shape (difference in log length/height ratio). Sexual dimorphism was directly estimated for 75 of the 101 species documented in this fauna; dimorphism in 20 more species was estimated as the mean dimorphism of their genus. We applied capture-mark-recapture analysis to species occurrences in 30 analytical samples (resolution of nearly equal 0.5 myr). We tested a variety of models for origination, extinction and preservation, including those that specify origination and extinction as dependent on the strength of sexual dimorphism. Initial results suggest that the probability of extinction increases with increasing size (but not shape) sexual dimorphism. Such a finding has implications for understanding the drivers of biodiversity over time and for managing current conservation efforts.

The fan systems, centered at about 20.5 degrees S, 69.4 degrees W are active at about decadal frequency. Individual flows extend 20-30 km across the basin, with individual flows averaging about 0.5 meters deep but nearly equal 1 km across. Individual deposits are typically 5-25 cm thick with a matrix averaging roughly 15% expandable clay, 40% silt, and 45% sand, mixed with variable amounts of fine gravel. Near the fan apex flows are partly channelized, but downstream the flows occur as shallow, braided flows with extensive overbank deposits. The mudflows also transport a small proportion of coarse gravel to boulders, deposited as bars and one- or two-boulder wide levees. Some of the boulders are rip-up clasts from earlier events. The coarse component is primarily transporting by rolling across the smooth fan surface. The mud deposits are susceptible to wind erosion, so that older flows become covered by a dark armor of granules to pebbles. Individual flows only partially follow the path of earlier flows, with frequent creation and abandonment of individual channels. The thick fan deposits are therefore composed of thousands of thin, interlaced mud deposits with granule or pebble deflation lags and scattered boulders and boulder bars associated with channels.

A case study in Mio-Pliocene plants of the Southeast AN - 1861101120; 787339-96 AB - Multiple studies now link ecological traits, such as seed dispersal, to macroevolutionary trends in diversification and extinction, in turn influencing geographic range size and related factors. While much research has focused upon the influence of these factors on community composition, relatively little work has been done documenting the pattern and tempo of these ecological changes. We here compare the patterns of range collapse and extinction in four Miocene through Pliocene floras in the eastern United States. These floras are noteworthy in having experienced less climate change than most other North American fossil floras of comparable or earlier age. As a result, comparison of changes in the composition of these floras relative to their modern analogs is less likely to be influenced by differences in major habitat transitions (e.g. forest to desert), unlike most western interior North American fossil floras. Preliminary results suggest that genera possessing biotic dispersal are less likely to undergo geographic range collapse or become extinct than genera that are abiotically dispersed; however, these results are not statistically significant with our current sample size. Additional fossil floras from the Oligocene and Miocene have yet to be analyzed. Further data may be available from late Miocene analogs to the California coastal mountain forests from Nevada, which can then be compared to patterns in the east. Updated data and results will be presented at the meeting.

Volcanic activity is responsible for this relatively new surface. The timing, size, and distribution of recent volcanic deposits have implications for which of the endmember models, catastrophic or equilibrium resurfacing, dominated this activity on Venus. Here we analyze the extent of parabolic impact crater ejecta, interpreted as some of the youngest deposits on Venus, and their stratigraphic relationships with different terrains, such as the tesserae and low-lying plains, to search for recent volcanic activity. Measurements of the backscatter coefficient from Magellan SAR left-look data are used to determine if there is a non-uniform distribution of crater ejecta superposed on the ancient highly deformed tesserae and low-lying plains materials. At Sudenitsa Tesserae, one of our study regions, several areas of low radar backscatter are identified in tessera materials, while no areas of low backscatter are found in the adjacent low-lying plains. The most plausible source of low backscatter material is the parabolic ejecta from relatively recent impact events. There is no obvious source crater for the low backscatter material at Sudenitsa. However, the location of Sudenitsa Tesserae on the northwestern border of the Beta-Atla-Themis (BAT) region, with 2-4 times the number of volcanic features observed on the rest of the planet, may explain the absence of a source crater. For instance, recent north-trending lava flows sourced from Polik-mana Mons, to the south of Sudenitsa Tesserae, may have resurfaced the source crater and some/all of the parabolic ejecta. The presence of the low backscatter material in Sudenitsa Tesserae and a missing source crater suggests that the parent impact crater was recently resurfaced (likely less than 80 Ma). A low-eruption rate lava flow sourced from the BAT region is capable of burying the source crater and some or all of the parabolic ejecta on the low-lying plains, consistent with equilibrium resurfacing models.

Here we show the spatiotemporal dynamics of species diversity in the Western Pacific through the Cenozoic, focusing on the tropical Indo-Australian Archipelago (IAA) biodiversity hotspot. We analyzed well-preserved fossil ostracodes from the tropical Western Pacific and combined their diversity data with other published data from the region to reconstruct Cenozoic dynamics of species diversity in the tropical- and northwestern Pacific Ocean. We fit generalized additive models to test for differences in richness over time and across geographic regions while accounting for sample size variation among samples. Low-, mid- and high-latitude regions all show a similar diversity trajectory: diversity is low in the Eocene and Oligocene, increases from the Early Miocene to the Plio-Pleistocene but then declines to the present day. Latitudinal diversity patterns are relatively flat and rarely show the typical decline from tropics to high-latitude. Modern-level high biodiversity in the tropical IAA and the northwestern Pacific Ocean was established during the Pliocene. The modest diversity decline from the Plio-Pleistocene to the present day may be attributable to large amplitude glacial-interglacial climate and sea-level changes. The weak and irregular (i.e., inverse, mid-latitude-peaked, or mid-latitude-depressed) latitudinal species diversity gradients are unexpected, because the northwestern Atlantic Ocean displays a standard tropical-high and temperate-low diversity pattern throughout the Cenozoic. In addition, ostracodes are known to show standard latitudinal diversity gradients in the North Atlantic. These differences suggest an important role for regional factors (e.g., plate tectonics and temporal geomorphological dynamics), in shaping the biodiversity of the Western Pacific.

In our study, we use ostracode microfossils as a model system for evaluating modern ecosystem diversity and assessing the impacts of climate change on large-scale biodiversity pattern during the geologic past. Based on our modern equator-to-pole ostracode dataset, which covers 558 sites and >150,000 specimens in the western North Atlantic and Arctic Oceans, we observed a diversity gradient with a maximum in tropics and decreasing diversity towards the Arctic. We also compared the modern diversity patterns to those during past interglacial periods in the Pliocene (5.33-2.58 Ma) and the Pleistocene Marine Isotope Stage 5 (125,000 yrs ago), using fossil ostracode assemblages. Results suggest that Pliocene and Pleistocene climate changes affected large-scale biodiversity patterns in the North Atlantic Ocean, including geographic shifts in the location of diversity maxima.

While all major continents once harbored giant mammals such as mammoth, woolly rhinoceros, mastodon, camels, llamas, and/or horses, few of these extremely large-bodied species remain, and they are mostly confined to the African continent. This decline mirrors the movement of modern humans across the globe and has intensified as human populations increased and expanded over the late Quaternary. Yet, the consequences of this prolonged loss of megafauna biodiversity have been understudied. Here, we quantify a number of important macroecological patterns of mammals over time to investigate how the loss of megafauna has influenced the shape and functioning of ancient and modern ecosystems and what modern ecosystems will likely look like in the future. Specifically, we focus on Africa, Eurasia and the Americas. Using a late Quaternary database (MOM v6.0) of mammals, we quantify the shape of the body size distribution, energy and biomass flow, and species diversity patterns at 6 time periods: 100ka, 20ka, 10ka, 0.3ka, modern and 0.2 ka years in the future. These time periods correspond to the dispersal of modern humans from Africa across the globe, before and after their entry into the Americas, European migration, and 200 years post modern. We assume that all mammals currently endangered become extinct. Our results show an increasing homogenization of ecosystems; although the continents experienced megafauna biodiversity losses of varying intensity at different times, future macroecologial patterns will be similar on each. Because megafauna have a disproportionate influence on ecosystem structure and function, ecological interactions between species, and even biogeochemical cycling, our results strongly suggest that continued "trophic downgrading" may lead to unanticipated effects that influence virtually all aspects of ecosystems.

N1 - Last updated - 2017-01-24 ER - TY - JOUR T1 - Linked Shifts in Glacial-Interglacial CO2, Climate and Terrestrial Carbon Cycling During Earth's Last Icehouse AN - 1861087058; 784670-15 AB - Earth's last icehouse (325 to 260 Myr) is considered the longest-lived and most acute of the past half billion years, characterized by widespread continental ice sheets and possibly tropical low-elevation glaciation. This atypical climate has long been attributed to anomalous radiative-forcing promoted by a 3% lower incident solar luminosity and sustained low atmospheric CO2 (=300 ppm). Existing late Paleozoic CO2 reconstructions, necessary to resolve this radiative-forcing conundrum and to better understand paleoclimate dynamics, are of insufficient resolution and poorly constrained. We present an integrated pedogenic carbonate and fossil cuticle reconstruction of atmospheric CO2 through 16 million years of the latter half of the Pennsylvanian and earliest Permian developed using a cyclothem series in the Illinois Basin as well as a subset of samples from the Appalachian and Donets basins. Overall, reconstructed CO2 falls below the modeled threshold (560 ppm) for late Paleozoic glacial inception, well within the range of ice sheet stability during the LPIA (up to 840 ppm). The suborbital resolution reveals CO2 variations between approximately 200 and 700 ppm with an apparent long eccentricity pacing. Short-term CO2 fluctuations are superimposed on a 106-yr CO2 trend that varies in-step with major sea level changes and glacial advances and retreats inferred from Donets Basin and Midcontinent stratigraphic trends. Comparison of the CO2 reconstruction with published paleobotanical records for tropical Euramerica indicates a coincidence between CO2 changes and repeated restructuring of Pangaean tropical forests. Integration of these empirical records with modeled vegetation shifts for the late Paleozoic indicate a more dynamic carbon sequestration history than previously considered and a major role for terrestrial vegetation-CO2 feedbacks in driving eccentricity scale climate cycles of the late Paleozoic icehouse.

Dunfee, Nevada, USA AN - 1861086398; 784664-95 AB - Here we report new stratigraphic, paleontological, and geochemical data from exposures at Mt. Dunfee, Nevada, USA, which preserve the last appearance datum (LAD) of Ediacaran biota, the LAD of Cloudina, the first appearance datum (FAD) of vertical burrows preserved as the trace fossil Treptichnus pedum, and a large negative d13C excursion in carbonate strata. The Ediacaran body fossil assemblages from the Deep Spring Formation include exceptionally preserved specimens of Conotubus, Gaojiashania, other vermiform body fossils, and possible Wutubus annularis. This is the first definitive report of Conotubus and Gaojiashania outside of South China, extending the known stratigraphic and biographic ranges of these taxa to a global scale. The younger of the two fossil assemblages occurs within the basal Cambrian negative d13C excursion, establishing it as the youngest Ediacaran fossil assemblage discovered to date. We further discuss how these sections correlate with better-known successions exposed in Death Valley and globally. The integrated dataset from Mt. Dunfee demonstrate that a large perturbation to the carbon cycle coincided with major biological turnover and the radiation of bilaterian metazoan ecosystems across the Ediacaran-Cambrian transition.

During the Supergreenhouse interval meridional temperature gradients were very low and oceanic deposition was punctuated by episodes of widespread anoxia, termed Oceanic Anoxic Events (OAEs) resulting in large scale burial of organic carbon reflected in positive delta 13C excursions. High CO2, greenhouse climate conditions are envisioned for the near future calling for action to get a better understanding of their potential impacts and dynamics. Climate models have identified significant geography-related Cenozoic cooling arising from the opening of Southern Ocean gateways, pointing towards a progressive strengthening of the Antarctic Circumpolar Current as the major cause for cooler deep ocean temperatures. Analogous arguments point to an important role for deep circulation in explaining Late Cretaceous climate evolution. The Agulhas Plateau is located in a key area for retrieving high-quality geochemical records to test competing models, e.g. to what extent and exactly when the opening of Drake Passage contributed to cooling of the deep ocean. The proposed drill sites on Agulhas Plateau and Transkei Basin are at high latitudes (65 degrees S-58 degrees S from 100 to 65 Ma) and within a gateway between the newly opening South Atlantic, Southern Ocean and southern Indian Ocean basins. Recovery of expanded and stratigraphically complete pelagic carbonate sequences from this region, and comparison with drilling results from Naturaliste Plateau (760-Full), will provide a wealth of new data to significantly advance the understanding of how Cretaceous temperatures, ocean circulation, and sedimentation patterns evolved as CO2 level rose and fell, and the breakup of Gondwana progressed.

Nevertheless, many sections around the world have been documented that demonstrate encouraging, if so far not comprehensive, sets of data, with demonstrated correlatory power to at least decadal levels. These are sited within a range of sedimentary settings that include polar snow and ice layers (for proxies including radionuclides, d18O, CO2 concentrations and d13C, increased dust flux/lead aerosols, annual layers), lakes at various latitudes (d15N, microfossils, particulates including fuel ash and plastics, persistant organic pollutants - POPs), tree rings (14C, d13C, annual layers), growing peat bogs (fly ash), marine anoxic basins (annual laminites, microfossils, radionuclides, fly ash, microplastics, POPs), speleothems (chemical/isotope patterns), accumulations of anthropogenic material (technofossil stratigraphy) and others. Together these encompass a wide range of proxies and geography, and a number can be independently dated radiometrically (e.g. by 210Pb). To make progress, a small number of potentially optimally representative sites needs to selected for preliminary examination, for which more systematic and comprehensive datasets then need be obtained, with correlation established between these and other sections. We suggest that, initially, analysis of this kind be focused around the mid-20th century level, although this should not exclude comparable analysis of other potential boundary levels. Such an exercise should help in suggesting a candidate primary GSSP with additional auxiliary reference sections, as with the Holocene GSSP. We note that the possibility of a GSSA boundary, or of some combination of GSSP and GSSA should not be excluded, for precision of boundary location within the human as well as geological calendars. More widely, an exercise of the kind we propose would undoubtedly help illuminate the large and complex global changes associated with the Anthropocene concept.

Planktonic foraminifera at Tanzania Drilling Project (TDP) Site 39 are diverse and the occurrences of Tethyan marker species enable application of the tropical biozonation. The topmost 70.18 m of the section are assigned to the Dicarinella asymetrica Zone, while the underlying sediments belong to the Dicarinella concavata Zone. In addition, TDP 39 is proposed as reference section for the Coniacian/Santonian boundary in the Indian Ocean with the boundary placed at the lowest occurrence of Globotruncana linneiana in agreement with the sequence of events defined at the GSSP stratotype section in Spain. The sedimentary record at TDP 39 was deposited in an outer shelf to upper slope setting dominated by calcareous clayey siltstones and mudstones and, thus, provides a unique opportunity to document the planktonic foraminiferal evolution in a subtropical marginal sea environment. Specifically, the Coniacian-Santonian interval represents a key-period in the evolutionary history of planktonic foraminifera during which deep dwelling taxa underwent a major radiation (originations outnumbered extinctions) that has been related to a series of climatic and oceanographic changes. Combined documentation of lithological and geochemical data from TDP 39 reveal a paleoceanographic history influenced first by a high transfer of continental-derived nutrients to surface waters in the D. concavata Zone that shifts to higher carbonate production and reduced surface water primary productivity in the overlying D. asymetrica Zone. Planktonic foraminiferal assemblage changes mirror the depositional and geochemical trends and indicate a progressive change from a more eutrophic to a more oligotrophic regime associated with both a well-defined mixed layer and a stable thermocline. At the local scale, this paleoceanographic scenario is consistent with the deepening of coastal Tanzania in response to the widespread, Late Cretaceous marine transgression registered on the passive margin along southeastern Tanzania after the separation of Madagascar from India at approximately 93 Ma. Epicontinental invasion of oligotrophic waters during the high sea-level stand may have provided increased opportunities for planktonic foraminifera to exploit new ecological niches. Because the tectonic evolution and sea-level rise along the East Africa continental margin is superimposed on the global long-term sea-level high documented for the Coniacian-Campanian time interval, we hypothesize that the epicontinental invasion of blue water may have favoured the evolution of new lineages within the deep-dwelling taxa.

Evidence of importance to the formalization question may be placed within the standard litho-, chemo- and bio-stratigraphic categories, while there are a number of novel phenomena. Lithostratigraphic evidence includes the appearance and rapid, near-isochronous, dispersal of many new mineral forms (including metals, plastics and industrial fly ash), rock types (including concrete and brick) and sediment bodies including artificial ground, landfill and marine trawl layers together with sediments released by land use changes. Humans now move more terrestrial sediment than all natural horizontal fluxes by water (rivers), wind (aeolian), and ice (glaciers). Chemostratigraphic evidence includes isotope patterns altered by perturbations to the carbon, nitrogen and phosphorus cycles at rates and magnitudes unprecedented in Quaternary times, atmospheric gas changes preserved in ice, disseminated metal and persistent organic pollutant and artificial radionuclides traces, many of which are novel signatures. Biostratigraphic evidence includes preservable consequences of extinctions, geologically unprecedented species invasions and marked assemblage changes. Recent climate and sea level trends are outside the Holocene trajectory, though global temperature and sea level are still within the Quaternary interglacial envelope. Anthropogenic influence on stratigraphic signals commenced thousands of years ago, but the most pronounced inflection in most trends away from Holocene patterns is in the mid-20th century2. The evidence in sum may be used to justify an epoch-scale boundary, though questions of utility and of definition - including selection and detailed multiproxy analysis of candidate GSSP sections - remain. We provide a summary of the balance of opinion within the working group on the major questions regarding the geological reality, potential boundary markers, hierarchical level and formalization potential of the Anthropocene.

It is the prime vehicle for incorporating updates to the International Geologic Time Scale. An evolutionary-tree function has recently been added to TimeScale Creator, allowing trees to be seamlessly scaled against the entire event suite, and to employ built-in visualization features such as continuous zoom to desired levels of precision. Stratigraphic ranges of taxa on the trees can be graded by abundance, color coded by taxonomic or other criteria, and easily recognized by thumbnail images magnified relative to actual size. For each taxon a mouse-over pop-up can display diverse user-chosen text and visuals such as hot-links to external sites, taxonomic information, and labeled images ordered by, e.g., stratigraphic position. This content can be generated from a back-end relational database, which becomes a valuable resource in itself. So, what have been static, stand-alone evolutionary trees, published as text-figures or derived from phylogenetic programs, can become a living resource and knowledge base of evolution and stratigraphy. As part of the on-going development of the TimeScale Creator evolutionary-tree function, a taxonomic study of extraordinarily well-preserved Cenomanian-Coniacian biserial planktic was chosen to assess the relevance of the visualization tool. As the published tree was presented against an up-to-date time scale, conversion to the TimeScale Creator could provide only relatively minor overall improvements to the tree. These included: explicit correlation to other zonations relevant to range determinations referred to in the study; automated labeling of origins of genera; and display of entire stratigraphic ranges for taxa extending higher than the scope of the published tree. The visualization includes several features that provide flexibility for presentation of varying degrees of certainty and access to extra information. Conjectured range extensions are shown to identify stratigraphic intervals that should be targeted for follow-up investigations of species whose ancestor-descendent relationships are not understood. Mouse-over pop-up windows provide quick access to more nuanced stratigraphic information, including detailed comments and references to the relevant literature. Illustrated specimens are displayed in order of location and stratigraphic level within their species pop-up, providing a powerful illustration of infra-specific variation observed up-section. Also, thumbnail images selected for the tree can be magnified relative to actual size; given that size was an important element of the evolution of lineages in this group, this providing a much more pertinent means of display for the tree. Categorization of the evidence for the ancestor-descendant proposals in the visualized tree provided added insights into the published study's reconstruction of phylogeny. Of more general significance, such an approach could prove to be the beginnings of a template for standard documentation in taxonomic studies employing stratophenetic methods and encourage their incorporation into project planning. Given that e.g. cladistic approaches to phylogeny provide a highly explicit approach to presentation and analysis of evidence, the raising of this issue could prove timely for contemporary biostratigraphic studies wanting to employ stratophenetic approaches.

These cores were drilled with the initial expectation of recovering relatively complete lacustrine sections suitable for paleoclimatic reconstructions. However, visual and other analyses have revealed numerous intervals of pedogenic overprinting in almost all cores. Although pedogenesis is a time-averaged paleoenvironmental record, it is important to understand the reason for repetition (and possible cyclicity). Techniques from outcrop studies can be useful for reconstructing paleoclimate from these pedogenic intervals, such as: paleosol drainage class, thickness, horizonation, color, and carbonate development, all of which can be used to calculate soil maturity. Bulk geochemisty of the paleosols indicates degree of weathering, paleoprecipitation, and chemical and physical properties affecting soil fertility. Combining these physical and chemical methods, along with accompanying lithological and paleontological data, in a sequence stratigraphic approach, provides information on climatic or tectonic influences on deposition. Two cores were recovered in 2012 from the Koora Graben, approximately 20 km southeast of the archaeologically-rich Olorgesailie basin in southern Kenya. These deposits contain fluvial fining upward successions with floodplain paleosols and intervals of pedogenically overprinted lacustrine mud or diatomite. Over 30 individual paleosols have been identified in 216 m of sediment from the two drilling sites. These paleosols are either weakly developed paleo-Entisols or -Inceptisols or moderately developed clay-rich paleo-Vertisols with pedogenic carbonate and vertic features. Preliminary bulk geochemical data indicate that the mean annual precipitation (MAP) ranged from approximately 750-1000 mm/yr during the episodes of pedogenesis. This MAP estimate is significantly higher than the modern Koora Plain, which ranges from 300-500 mm/yr.

An organism's ability to disperse may be restricted by barriers such as oceans, or enhanced by innovations such as powered flight. Most paleobiogeographical methods that are currently used to model the dispersal history of clades require a priori designation of discrete areas. Here we instead combine continuous paleocoordinate data with phylogenetic data to infer the development or breakdown of barriers to dispersal through time. Mesozoic dinosaurs present an ideal case study for this framework; the history of the clade spans the break-up of Pangea and the origin of a probable dispersal enhancing trait--powered flight. Using occurrence data from the Paleobiology Database and a 1000-taxon supertree we test a set of predictions relating to key events in dinosaur evolutionary history. Initial results based on a simple correlation approach are consistent with the break-up of Pangea acting to decrease dispersal, and with powered flight acting to overcome all barriers to dispersal. Additionally we present a simulation framework that can be used to generate expected distributions of phylogenetic distance under different dispersal scenarios, implemented in R (github.com/laurasoul/dispeRse). This is based on treating dispersal of a speciating clade as bounded Brownian motion on a sphere, while new barriers are created (continental break-up) or removed (continental collision). Extension of this framework will allow investigation and modelling of the acquisition of dispersal enhancing traits such as flight or aquatic locomotion, as well as of geographic scenarios such as sea level change and the presence of land bridges.

The resistance to water movement of cells between the veins and the stomatal pores is orders of magnitude higher than the hydraulic resistance of the veins. Decreasing the path length through the living tissue by increasing the density of veins (Dv) lowers the resistance of the system as a whole. An important evolutionary pattern rises from the link of Dv and physiology: flowering plants can have a Dv three or four times higher than any other plants. The higher physiological rates associated with high vein density also require higher stomatal conductances, but stomata and veins-and the photosynthetic tissue supported-might end up competing for space on the leaf at high densities. The reason stomata and veins cannot simultaneously occupy the same epidermal area is that all plant lineages can have bundle sheath extensions (BSE)-densely packed cells that link the vein to epidermis and exclude stomata. We measured the occupation of the leaf surface across Angiosperm canopy trees, supplemented by additional measurements in ferns and gymnosperm seed plants. In rain forest trees, it is typically found that stomata occupy 6%-14% of a leaf and veins 13%-25% (max 60%). However, for a low vein density fern or gymnosperm, if the density of veins and stomata were simply scaled up, the leaf surface would be occupied entirely at vein densities far below those achieved by angiosperms. The diffuse leaf growth and hierarchical vein orders of flowering plants allows differential deployment of BSE across vein orders, so that high vein density leaves reduce occupation by lowering BSE density versus vein density. The marginal leaf growth, common to most non-Angiosperm leaves requires an all or nothing approach, consequently BSE limits the possibility of high vein density because all veins must be equally expressed in the epidermis.

Results suggest that the plutonic and volcanic activities are closely related to a common magmatic history. This volcano-plutonic association presents a well-defined LILE and LREE enrichment and negative Nb and Ti negative anomalies characteristic of continental magmatic arcs. Volcanic and plutonic rocks crystallized between 180-186 Ma as revealed by U-Pb zircon geochronology. The magmatic activity is temporally and chemically correlatable with other magmatic arc exposures in Colombia and Ecuador. These units may represent the remnants of a single belt which includes several units from 4 degrees N in Colombia and 5 degrees S in Ecuador. This arc is related to the widespread Jurassic continental magmatic arc setting that characterized the continental margins of the Americas after Pangea break-up.

N1 - Last updated - 2017-01-24 ER - TY - JOUR T1 - The Hell Creek Formation and its contribution to the Cretaceous-Paleogene extinction; a short primer AN - 1832678739; 768089-3 AB - Although it represents but one geographic data point, the uppermost Maastrichtian Hell Creek Formation (HCF), exposed in the upper Great Plains of the North American craton, remains the most studied source for understanding the final approximately 1.5 Myr of the Mesozoic Era in the terrestrial realm. Because it lies conformably below the earliest Paleocene Fort Union Formation, and together these two units preserve a rich fauna and flora, much of what is understood about the terrestrial Cretaceous-Paleogene (K-Pg) boundary comes from this sequence. The HCF has been reconstructed as an expansive, fluvially drained, low coastal plain, built out, to the west, against the Laramide Orogen, and to the east, against the ultimate transgression (Cannonball) of the Western Interior Sea. Its meandering rivers and moist soils supported a multi-tiered angiosperm-dominated flora and rich insect and vertebrate faunas, including dinosaurs, crocodilians, squamates, turtles, and mammals. A dramatic facies change representing the initiation of catastrophic flooding is preserved, within available levels precision, at the K-Pg boundary. High-precision stratigraphy has proven difficult in this lenticular fluvial system. Where present, the boundary can be recognized by the bipartite boundary claystone; otherwise, palynostratigraphy has proven a powerful tool. Numerical dates have been successfully obtained from in tonsteins at the boundary and above, in the Fort Union; however, these have proven elusive below the boundary within the HCF. The K-Pg boundary in this region is dated at 66.043 Ma (Renne et al., 2013). Magnetostratigraphic studies have been carried out in the HCF; although all but one have lacked numerical dates, these have been used for correlations of widespread, disjunct exposures and for the estimation of sedimentation rates. The palynoflora is largely homogenous through the HCF; at the K-Pg boundary, it shows an abrupt approximately 30% extinction. This makes it a powerful tool for identification of the K-Pg boundary, although because the boundary is identified on absence of Cretaceous taxa rather than presence of earliest Paleocene taxa, several competing methods have been applied to identifying the K-Pg boundary using pollen. The macroflora, consisting largely of leaves, consists of three successive floras, showing increasing diversity through the HCF. The ultimate of these three floras undergoes an abrupt 57% extinction; taken as a whole, however, the macroflora undergoes a 78% extinction at the K-Pg boundary. The best data available for dinosaurs - including archaic Aves - show an abrupt extinction. By contrast, salamanders and other lissamphibians, as well as chelonians, cross the boundary virtually without perturbation. Squamates appear to have suffered significant extinctions at the K-Pg boundary, as did euselachians (elasmobranchs) and insects. Mammals suffered a 75% extinction; however, some of this figure cannot be shown to have occurred in less than the last 500 kyr of the Cretaceous, and thus has been potentially attributable to causes other than a bolide impact. Taken together, the survivorship patterns are concordant with the catastrophic inception of ubiquitous flooding characterizing the K-Pg boundary. While the key K-Pg boundary question in the HCF was once the rate of the biotic extinction, it has moved to the distinction between single-cause scenarios, with the Chicxulub bolide as agent of extinction, and multi-cause scenarios, uniting habitat partitioning, Deccan flood-basalt volcanism, climate change, competition, and bolide impact. Not every potential environmental perturbation need be a mechanism for the extinction: parsimony and the data continue to be concordant with a bolide impact as the single agent of the terrestrial K-Pg mass extinction.

Armoring alters the land water interface and has the potential to affect nearshore submerged aquatic vegetation (SAV) by changing nearshore hydrology, morphology, water clarity, and sediment composition. We quantified the relationships between the condition (bulkhead, riprap, or natural) of individual shoreline segments and three measures of directly adjacent SAV (the area of potential SAV habitat, the area occupied by SAV, and the proportion of potential habitat area that was occupied) in the Chesapeake Bay and nearby Atlantic coastal bays. Bulkhead had negative relationships with SAV in the polyhaline and mesohaline zones. Salinity and watershed land cover significantly modified the effect of shoreline armoring on nearshore SAV beds, and the effects of armoring were strongest in polyhaline subestuaries with forested watersheds. In high salinity systems, distance from shore modified the relationship between shoreline and SAV. The negative relationship between bulkhead and SAV was greater further off shore. By using individual shoreline segments as the study units, our analysis separated the effects of armoring and land cover, which were confounded in previous analyses that quantified average armoring and SAV abundance for much larger study units (subestuaries). Our findings suggest that redesigning or removing shoreline armoring structures may benefit nearshore SAV in some settings. Because armoring is ubiquitous, such information can inform efforts to reverse the global decline in SAV and the loss of the ecosystem services that SAV provides.

The ornithomimid from the Bissekty Formation is documented by more than 800 isolated bones that represent much of the skeleton. It shows at least three unambiguous synapomorphies of Ornithomimidae: length of anterior cervical centra three to five times greater than transverse width; low and rounded fibular crest of tibia; metatarsal III pinched between metatarsals II and IV; and proximal end of metatarsal III not visible in anterior view. Phylogenetic analysis, based on a dataset with 568 morphological characters and including all known ornithomimosaurian taxa, places the ornithomimid from the Bissekty Formation near the base of the ornithomimid radiation, between Archaeornithomimus asiaticus and Sinornithomimus dongi.

Seasonal upwelling in the tropical eastern Pacific provides an ideal system in which to test these ideas. During the non-upwelling season, the Bay of Panama is warmer, less saline and less productive than during the upwelling season. We followed egg deposition of 4 intertidal gastropod species-Littoraria variegata, Cerithideopsis californica var. valida, Crepidula cf. marginalis and Natica chemnitzi-to determine if these seasonal environmental differences are associated with variation in reproductive intensity or offspring size. The species from the mangroves, L. variegata and C. californica, produced fewer egg masses during the dry season. The slipper limpet C. cf. marginalis was more likely to brood during the dry season. Egg masses from the moon snail N. chemnitzi showed no difference in abundance between the seasons. Shell length at hatching, an estimate of per offspring maternal investment, was larger during the dry season for C. californica and C. cf. marginalis but did not differ across the seasons for L. variegata. Hatching size in the moon snail was bimodal during the dry season, but both offspring size classes showed increased offspring size in the dry season compared to the wet season. Three of the 4 species show patterns in offspring size consistent with the offspring temperature-size rule, while seasonal cycles in reproductive intensity are likely driven by other factors such as adult food availability or desiccation stress.

However, the sequence of events leading up to a successful capture or detection is susceptible to biases introduced through individual-level behaviour or physiology. Passive sampling techniques may be especially prone to sampling bias caused by size-related phenomena (e.g., physical limitations on trap entrance). We tested for size-biased sampling among five types of passive traps using a 9-year data set for two species of aquatic salamanders that have a 20 and 61 fold change in length over their ontogeny (Amphiuma means, Siren lacertina). Size-biased trapping was evident for both species, with body size distributions (body length mean and SD) of captured individuals differing among sampling techniques. Because our two species differed in girth at similar lengths, we were able to show that size biases (in length) were most likely caused by girth limitations on trap entry rates, and potentially by differences in retention rates. Accounting for the biases of sampling techniques may be critical when assessing current population status and demographic change.

However, complex dune shape can often complicate the interpretation of this sand movement record. Here we describe a technique for monitoring such dune position and shape changes without the necessity of obtaining expensive repeat coverage by airborne LiDAR data. We used differentially corrected global positioning system (DGPS) data to document the precise location of the crest and base of an active reversing sand dune at Great Sand Dunes National Park and Preserve in central Colorado, but the procedure we employed should be applicable to the study of any active sand dune. A Trimble GeoXH with postprocess differential correction provided three-dimensional positional data to better than 20 cm, sufficient to record the shape of the dune in detail. When imported into ArcGIS, the surveyed points were combined using a triangulated irregular network that captured the overall shape and location of the dune. These data could then be compared to an earlier LiDAR digital elevation model of the park, from which we could assess how the sand dune shape and location changed during the time between the two surveys. We intend to continue to monitor this same dune, along with other nearby dune forms, to evaluate the timescale over which such changes can be effectively obtained under the wind conditions prevalent at the park. We are optimistic that the procedure we successfully employed can be applied to studies of sand dunes wherever precise DGPS surveys can be conducted.

Although 'upside-down' epibenthic jellyfish in the genus Cassiopea also derive a substantial metabolic benefit from abundant communities of the dinoflagellate symbiont Symbiodinium, comparatively little is known about the efficiency of carbon (C) and nitrogen (N) assimilation within the Cassiopea holobiont. Using standardized 6 h incubations with super(13) C- and super(15) N- enriched compounds, we assessed symbiont C and N assimilation in both oral arm and bell tissue of C. xamachana under light and dark conditions. Carbon fixation was light dependent and highest in the photosymbiont-rich oral arm tissue. In contrast, super(15) NO sub(3) assimilation was light independent in both tissue types and was highest in bell tissue that was sparsely colonized by photosymbionts. This, coupled with higher bell tissue super(15) N enrichment under dark conditions, implicates non-photosynthetic microbes in Cassiopea N metabolism. This zonation of microbial activity may allow C. xamachana to simultaneously fix C and assimilate ambient or porewater N released during Cassiopea pumping activity. Although C. xamachana may utilize symbiont-derived N, lower super(15) N enrichment relative to C fixation suggests that Cassiopea may also rely on exogenous sources of N for growth. This study provides initial evidence that the efficiency of symbiont metabolism within Cassiopea jellyfish is comparable to, or exceeds, that of other common benthic marine invertebrates, supporting the contention that Cassiopea have an important role in the productivity and nutrient dynamics within their local environment.

Benthic habitats that increase coral recruitment are a key factor for coral persistence, but very little is known about habitat selectivity for larvae of most species of corals. The larval settlement preferences and post-settlement survival of 3 brooding and 4 broadcast spawning coral species were compared in this study. The crustose coralline algae Titanoderma prototypum and Hydrolithon boergesenii facilitated larval settlement more than the biofilm control for the broadcast spawning corals but not for the majority of the brooding corals. In paired choice experiments, the larvae of all 7 corals preferred T. prototypum over Paragoniolithon solubile, and 6 of them preferred H. boergesenii over Pa. solubile, the exception being larvae of Porites astreoides. All corals equally preferred T. prototypum and H. boergesenii, except Pseudodiploria strigosa, which preferred T. prototypum, and Acropora palmata, which preferred H. boergesenii. Some recruits from the 3 brooding corals survived longer than 1 yr in the field, but of the 4 spawning corals, only P. strigosa had 2 recruits that survived >1 yr. Corals that spawned their gametes had increased settlement in the presence of a few species of coralline algae, but corals that brooded their larvae settled on biofilms and had much greater post-settlement survival, suggesting that the recruitment of brooding corals will dominate on reefs without facilitating species of crustose coralline algae.

Understanding how species respond to changes in DO and pH is critical to predicting how climate change will affect estuarine ecosystems, including the extreme shallow margins of these systems, where factors such as respiration, photosynthesis, and tides create daily fluctuations of DO and pH, and strong correlations between the 2 stressors. To determine how acidification affects the sensitivity to hypoxia of 2 important forage fishes, the silversides Menidia menidia and M. beryllina, we recorded opercula ventilation rates, aquatic surface respiration (ASR, where fish breathe in the oxygenated surface layer during hypoxic events), and mortality as we lowered either DO or both DO and pH simultaneously. Fish subjected to low DO and low pH in the laboratory performed ASR and died at higher DO concentrations than fish subjected only to hypoxia. Additionally, fish beat their opercula slower, which may have contributed to the differences in ASR and mortality that we saw. These results indicate acidification can increase mortality under hypoxia not only directly but also indirectly by increasing vulnerability to predation during increased use of ASR.

Field observations suggest that mafic, water-rich magmas often intrude viscous felsic crystal-rich mushes. This scenario can advect water from the crystallising mafic magma to the felsic magma, leading to an increase in melt fraction in the felsic mush and subsequent mobilisation, at the same time as the mafic magma becomes quenched through a combination of cooling and water loss. To investigate such a scenario, we conducted experiments on a water-undersaturated (4 wt% H sub(2)O in the interstitial melt) dacitic crystal mush (50-80 vol% quartz crystals) subject to volatile supply from a water-saturated ( greater than or equal to 6 wt% H sub(2)O) andesite magma at 950 degree C and 4 kbar. Our experimental run products show unidirectional solidification textures (i.e. comb layering) as crystals nucleate at the mafic-felsic interface and grow into the mafic end-member. This process is driven by isothermal and isobaric undercooling resulting from a change in liquidus temperature as water migrates from the mafic to the felsic magma. We refer to this process as "chemical quenching" and suggest that some textures associated with natural mafic-felsic interactions are not simply cooling-driven in origin, but can be caused by exsolution of volatiles adjacent to an interface, whether a water-undersaturated felsic magma (as in our experiments) or a fracture.

Rigorously evaluating pairing of howardites recovered in 1995 in the Grosvenor Mountains (GRO 95), Antarctica, enables an examination of a larger, more representative regolith sample. Previous work on two of the howardites studied here concluded that GRO 95602 and GRO 95535 are solar wind-rich surface regolith samples and that they are not paired with each other, leading to uncertainty regarding pairing relationships between the other GRO 95 howardites. Based on petrology, cosmic-ray exposure history, and terrestrial age, four GRO 95 howardites are paired. The paired howardites (GRO 95534, 95535, 95574, 95581) were from a meteoroid with radius of 10-15 cm, a preatmospheric size comparable to that of Kapoeta, the largest known regolithic howardite. The paired GRO 95 howardites contain clasts of at least 18 separate HED lithologies, providing evidence they were assembled from diverse source materials. The total eucrite:diogenite mixing ratio (ratio of all eucrite lithologies to all diogenite lithologies) in the paired GRO 95 howardites is approximately 2:1. Petrographically determined basaltic eucrite:cumulate eucrite ratios in regolithic howardites, studied here and previously, vary more widely than total eucrite:diogenite ratios. Relative to eucritic pyroxene, plagioclase is depleted in these howardites, which provides evidence that plagioclase is preferentially comminuted in the vestan regolith. The extent of plagioclase depletion could be an indicator of regolith maturity. Abstract Copyright The Meteoritical Society, 2015.

AN - 1790467809; 27196603 AB - Mineralized tissues accumulate elements that play crucial roles in animal health. Although elemental content of bone, blood and teeth of human and some animal species have been characterized, data for many others are lacking, as well as species comparisons. Here we describe the distribution of elements in horn (Bovidae), antler (Cervidae), teeth and bone (humerus) across a number of species determined by handheld X-ray fluorescence (XRF) to better understand differences and potential biological relevance. A difference in elemental profiles between horns and antlers was observed, possibly due to the outer layer of horns being comprised of keratin, whereas antlers are true bone. Species differences in tissue elemental content may be intrinsic, but also related to feeding habits that contribute to mineral accumulation, particularly for toxic heavy metals. One significant finding was a higher level of iron (Fe) in the humerus bone of elephants compared to other species. This may be an adaptation of the hematopoietic system by distributing Fe throughout the bone rather than the marrow, as elephant humerus lacks a marrow cavity. We also conducted discriminant analysis and found XRF was capable of distinguishing samples from different species, with humerus bone being the best source for species discrimination. For example, we found a 79.2% correct prediction and success rate of 80% for classification between human and non-human humerus bone. These findings show that handheld XRF can serve as an effective tool for the biological study of elemental composition in mineralized tissue samples and may have a forensic application.

While experimental elevation of CO sub(2) has revealed that young forests respond with increased productivity, there remains considerable uncertainty as to how the long-term dynamics of forest regrowth are shaped by elevated CO sub(2) (eCO sub(2)). Here, we use the mechanistic size- and age- structured Ecosystem Demography model to investigate the effects of CO sub(2) enrichment on forest regeneration, using data from the Duke Forest Free-Air Carbon dioxide Enrichment (FACE) experiment, a forest chronosequence, and an eddy-covariance tower for model parameterization and evaluation. We find that the dynamics of forest regeneration are accelerated, and stands consistently hit a variety of developmental benchmarks earlier under eCO sub(2). Because responses to eCO sub(2) varied by plant functional type, successional pathways, and mature forest composition differed under eCO sub(2), with mid- and late-successional hardwood functional types experiencing greater increases in biomass compared to early-successional functional types and the pine canopy. Over the simulation period, eCO sub(2) led to an increase in total ecosystem C storage of 9.7 Mg C ha super(-1). Model predictions of mature forest biomass and ecosystem-atmosphere exchange of CO sub(2) and H sub(2)O were sensitive to assumptions about nitrogen limitation; both the magnitude and persistence of the ecosystem response to eCO sub(2) were reduced under N limitation. In summary, our simulations demonstrate that eCO sub(2) can result in a general acceleration of forest regeneration while altering the course of successional change and having a lasting impact on forest ecosystems.

Here, we investigate this potent, yet underestimated, invasion vector using an important recipient region (the Mid-Atlantic) to examine the stepwise species transfer and survival along four stages of the vector. Location Maine and Mid-Atlantic region (New Jersey, Delaware, Maryland, Virginia and North Carolina), USA. Methods We quantified taxonomic identities and abundances of organisms associated with packing algae at four stages along the vector pathway during summer 2011: (1) Maine source habitats; (2) bait boxes from Maine distributors; (3) bait boxes from distributors in five Mid-Atlantic States; and (4) bait bags from retailers in five Mid-Atlantic States. We also examined functional diversity based on significant physical and life history characteristics and assessed genetic diversity for two common hitchhiking snail species. Results We identified 17,798 live macro-organisms across 58 taxa, including marine macro-invertebrates, macroalgae, vascular plants and semi-terrestrial or aquatic invertebrates, present in bait boxes and bags. In all measures of diversity and abundance, we observed decreases of live marine macro-invertebrates across sequential stages of the vector from source to recipient regions. Significant differences in community composition were also observed between stages and were driven by isopods (taxonomic diversity) and isopods, amphipods and some gastropods (functional diversity). Main conclusions The lack of management in the face of the sheer magnitude and diversity of organisms that are transported via the live marine bait trade underscores how this is an underappreciated vector that could be a considerable source of successful invasions globally.

We give an overview of the state of the art of our understanding on eustatic (global) versus relative (regional) sea level, as well as long-term versus short-term fluctuations and their drivers. In the context of the focus of UNESCO-IUGS/IGCP project 609 on Cretaceous eustatic, short-term sea-level and climate changes, we evaluate the possible evidence for glacio-eustasy versus alternative or additional mechanisms for continental water storage and release for the Cretaceous greenhouse and hothouse phases during which the presence of larger continental ice shields is considered unlikely. Increasing evidence in the literature suggests a correlation between long-period orbital cycles and depositional cycles that reflect sea-level fluctuations, implying a globally synchronized forcing of (eustatic) sea level. Fourth-order depositional sequences seem to be related to a approximately 405 ka periodicity, which most likely represents long-period orbital eccentricity control on sea level and depositional cycles. Third-order cyclicity, expressed as time-synchronous sea level falls of approximately 20 to 110 m on approximately 0.5 to 3.0 Ma timescales in the Cretaceous, are increasingly recognized as connected to climate cycles triggered by long-term astronomical cycles that have periodicity ranging from approximately 1.0 to 2.4 Ma. Future perspectives of research on greenhouse sea-level changes comprise a high-precision time-scale for sequence stratigraphy and eustatic sea-level changes and high-resolution marine to non-marine stratigraphic correlation.

This study focuses on plankton biostratigraphy and foraminiferal palaeoecology of the Radotruncana calcarata Total Range Zone. The Postalm section displays cyclic red deposits with marls and marly limestones, while we find uniform grey marls at Oberhehenfeld. The Oberhehenfeld section from the Ultrahelvetics can be correlated stratigraphically to the Postalm section using foraminifera, calcareous nannoplankton and stable isotope stratigraphy, and provides a point of comparison from the northern margin of the Penninic Ocean. The two sections show minimal difference in faunal composition and few distinct local stratigraphic signals. Paleoenvironmental trends from the late Campanian can be recognized relating the two sections from the Austrian Alps. The depositional water depth can be reconstructed as some 500-800 m. Plankton assemblages show a remarkable stability despite the sudden appearance and disappearance of R. calcarata, hinting at the late Campanian as a time interval of general foraminiferal stasis without significant evolutionary events. We speculate that the origin and extinction of R. calcarata are related to the prolonged evolution of ocean stratification during the Campanian from the Mid-Cretaceous sluggish hothouse during a time of general slow greenhouse climate decline.

The detailed evaluation of the long-term (3rd order) Aptian sea-level cycle results in the recognition of sea-level and climate as controlling factors on depositional environments in the basin. The rising part of the Aptian sea-level cycle lasted from the Deshayesites tenuicostatusis Zone to the Deshayesites deshayesi Zone, and transgression is responsible for the local development of anoxia on the Eastern Russian Platform. The Lower Aptian bituminous shales and sheeted calcite concretions associated with the Eastern Russian Platform are interpreted as being a regional manifestation of Oceanic Anoxic Event OAE 1a. The late Aptian "cold snap" that occurred during the Early Cretaceous greenhouse world coincided with a simultaneous global and regional sea-level lowstand, peak shallowing of the basin, and the almost complete absence of sediments due to subaerial exposure in the studied region. The global distribution of the lowstand gives clear evidence for sea-level fluctuations, and intrinsic climate control on sequences in the study area. Abstract Copyright (2016) Elsevier, B.V.

An alternative concept suggests that the water-bearing potential of groundwater aquifers is equal to that of ice caps and that changes in the dynamic balance of aquifer charge versus discharge, as a function of the temperature-related intensity of the hydrological cycle, may have driven eustasy during warm climates. However, this idea has long been neglected for two reasons: 1) the large storage potential of subsurface aquifers was confused with the much smaller capacity of rivers and lakes and 2) empirical data were missing that document past variations in the hydrological cycle in relation to eustasy. In the present study we present the first empirical evidence for changes in precipitation, continental weathering intensity and evaporation that correlate with astronomically (long obliquity) forced sea-level cycles during the warmest period of the Cretaceous (Cenomanian-Turonian). We compare sequence-stratigraphic data with changes in the terrigenous mineral assemblage in a low-latitude marine sedimentary sequence from the equatorial humid belt at the South-Tethyan margin (Levant carbonate platform, Jordan), thereby avoiding uncertainties from land-ocean correlations. Our data indicate covariance between cycles in weathering and sea level: predominantly chemical weathering under wet climate conditions is reflected by dominance of weathering products (clays) in deposits that represent sea-level fall (aquifer charge > discharge). Conversely, preservation of weathering-sensitive minerals (feldspars, epidote and pyroxenes) in transgressive sediments reflects decreased continental weathering due to dryer climate (aquifer discharge > charge). Based on our results we suggest that aquifer-eustasy represents a viable alternative to glacio-eustasy as a driver of cyclic 3rd-order sea-level fluctuations during the middle Cretaceous greenhouse climate, and it may have been a pervasive process throughout Earth history.

The studied succession (Ismailler Section) is located in the Mudurnu-Goynuk Basin, NW Turkey and dominated by apparently continuous pelagic muddy deposits. Stable isotopic and elemental compositions of the mudrocks are investigated in order to evaluate the paleoceanographic conditions as well as broad tectonic reconstruction of the basin. The mudrock geochemistry suggests a tectonic reorganization during late Campanian as reflected by a distinct shift from felsic to mafic sediment provenance. In the Ismailler Section, five delta (super 13) C events are identified; four or which are well correlatable with major events in other records around the world, such as the late Campanian Event (LCE), Campanian-Maastrictian Boundary (CMB) and the late Maastrichtian Event (LME). The relative sea-level variations in the basin typically match both short- and long-term global sea-level fluctuations. The remaining globally uncorrelatable delta (super 13) C event does coincide with tectonic uplift and the abrupt negative delta (super 13) C shift, and is inferred to be the result of regional factors. The dominance of worldwide events in the records of the relatively restricted ocean branch reflects the strength of global factors. Abstract Copyright (2016) Elsevier, B.V.

Recently published delta (super 18) O records from extremely well-preserved Turonian microfossils from Tanzania do not support the contentious idea of glacio-eustatic control of global sea-level changes during the warmest period of the Cretaceous. For the same locality (site TDP 31) we reconstruct relative sea-level changes based on sequence stratigraphy and integration of sedimentology, microfacies, geochemistry, and micropaleontology. Four local sequence boundaries (SBs TuTz1-4) are recognized: at the base, middle, and top of the Helvetoglobotruncana helvetica Zone and in the late Turonian. The lowstands are characterized by increased grain size, enhanced organic carbon flux, faunal assemblage changes, and bulk delta (super 13) C (sub org) and foraminiferal delta (super 13) C (sub f) and delta (super 18) O (sub f) minima. Strong benthic and planktic foraminiferal turnovers above the top middle Turonian SB TuTz3 probably reflect shallowing (from upper slope to outer shelf) and/or eutrophication. The TDP 31 age model is refined through inter-regional comparison of planktic foraminiferal ranges and delta (super 13) C records from three other South Tethyan localities (ODP Holes 762C and 763B, Exmouth Plateau, and the Guru section, Tibet). This age model enables correlation of the regressive events at a global scale and suggests that, within stratigraphic uncertainty, the TDP 31 depositional sequences are synchronous with the global Turonian third-order sequences and are likely driven by eustasy. These correlations, together with recent astrochronological and radiometric dating, indicate a considerably younger age (91.17 + or - 0.52 Ma) for the top H. helvetica Zone than currently assumed, resulting in zonal duration of 2.35 + or - 0.52 myr. Foraminiferal stable-isotope data from TDP 31 indicate slight surface- and bottom-water warming during the regressions and possibly a minor surface-water salinity decrease, which is inconsistent with glacio-eustatic forcing of Turonian third-order sea-level cycles and is more in line with the model of aquifer-eustasy.

At more distal sites, such as Stevns Klint (Denmark), there appears to be no sequence boundary at the Cretaceous/Paleogene boundary but there is one within the uppermost Maastrichtian, between the Sigerslev and Hojerup members, and another in the lowermost Paleocene (top of Zone P1a). Both of these surfaces are identified by distinctive, phosphatized, and incipient hardgrounds. The changes in sea level involved in the generation of uppermost Cretaceous sequences are thought to have been minimal as, in the Gulpen and Maastricht Formations of the Maastricht area (Netherlands), the presence of sea grasses and their associated foraminifera would indicate that the chalk sea floor remained within the range of water depth that would allow photosynthesis (< 20 m), even across the postulated sequence boundaries. The assemblages of foraminifera associated with sea grasses in the uppermost Maastrichtian are comparable in morphology with those associated with modern sea grass meadows and indicate a relationship that may have existed since, at least, the latest Cretaceous.

From a total of 98 species of the upper Maastrichtian, only 13 survived mass extinction, while the rest of the 86% vanished in the K-Pg fallout layer. A slight progressive decline in species richness and abundance was observed toward the top of the Maastrichtian, where mixed assemblages, consisting of both cold-water taxa and typical Tethyan ones are present. Four successive acme events were observed, i.e. Markalius inversus and the calcareous dinoflagellate genus Thoracosphaera starting from the base of the Paleocene, followed by those of Braarudosphaera bigelowii and Neobiscutum parvulum. The most prominent acme intervals belong to Thoracosphaera spp. and B. bigelowii, opportunistic taxa, for which the survival strategy may be linked to their capability to encyst and survive severe environmental deterioration. At the upper part of the studied succession, calcareous nannoplankton assemblages are already dominated by survivor species, as well as incoming ones, showing an early pioneer calcareous nannoplankton ecosystems about 35-40 kyr after the K-Pg boundary. Correlation between the calcareous nannoplankton assemblage fluctuation, including species richness and abundance, and the paleoenvironmental changes, such as the eustatic and climatic modifications, are also discussed.

The evolution and stratigraphic distribution of planktonic foraminifera and radiolarians in the Upper Cretaceous sediments of the region are described. The specialized, morphologically complex keeled taxa evolved in the latest Albian and persisted until the end of the Cretaceous. These overall evolutionary trends are punctuated by a series of bioevents, one of the most important being the Cenomanian-Turonian boundary. This is marked by a series of organic-rich sediments, that are related to an Oceanic Anoxic Event. The Turonian-Coniacian interval was marked by a further development of keeled taxa. A major change in the assemblage is described near the Santonian-Campanian boundary, when marginotruncanids were replaced by globotruncanids. The Albian is marked by the diversification of the radiolarian genus Crolanium, the last occurrence of which is typical of the Albian-Cenomanian boundary. The upper Coniacian to Lower Santonian strata are characterized by the high taxonomic diversity of the Quinquecapsulariidae and the Neosciadiocapsidae. A marked change in the radiolarian assemblage occurred at the Santonian-Campanian boundary: the late Santonian, warmer-water assemblage dominated by the Pseudoaulophacidae being replaced in the earliest Campanian by cooler-water assemblages characterized by the Prunobrachidae. The changes in the assemblages of planktonic foraminifera and radiolarians at the Santonian-Campanian boundary are attributed to changes in paleoceanography and the influence of more boreal-like conditions. Three significant episodes of sea level change can be identified in the Cenomanian-Campanian of the Crimea-Caucasus area. The first is associated with the Albian-Cenomanian boundary, the second at the base of OAE2, and the third in the mid-early late Turonian. This latter event had different durations in the Crimea and Caucasus regions and this could be related to more local tectonic processes. Abstract Copyright (2016) Elsevier, B.V.

The Sinop Basin in the Sakarya Zone is filled, from base to top, by Hauterivian to Albian turbidites, Cenomanian-Turonian red pelagic sediments, Turonian-Campanian magmatic-arc and related deposits, and by the uppermost Campanian to middle Eocene post-magmatic units developed on the southern passive margin of the Black Sea. Based on nannofossil, dinoflagellate, Foraminifera and Radiolaria data we describe the Kapanbogazi Formation, a Cenomanian-Turonian unit in the Sinop Basin, represented by red calcareous/siliceous pelagic shales, limestones and cherts passing gradually from the Albian black shales. These sediments possibly represent deepest depositional conditions of the basin during the Cenomanian-Turonian interval and also reflect the transition from an anoxic to an oxic palaeoenvironmental setting. The Istanbul Zone to the west was emerged during the deposition of the Kapanbogazi Formation in the Sakarya Zone. In the Pontides, red pelagic sediments were deposited at different times during the Cenomanian-Maastrichtian interval. Because the Kapanbogazi Formation was deposited only in the Sakarya Zone and because it is present in limited outcrops due to structural reorganization and thick overlying volcanoclastic pile, most previous authors assumed Cenomanian-Turonian hiatus.

AN - 1773796542; 2016-023415 AB - The major states, in which Earth's climate operates, i.e., icehouse, greenhouse and hothouse, are epochs of tens of millions of years. These states set long-term boundary conditions that need to be considered for climate and sea-level interpretations. This paper summarizes the conceptual models for hydrological cycling derived from the characteristics of these three climate states. While glacio-eustatic forcing of sea-level changes under icehouse climate conditions is fairly well understood, the drivers of eustatic sea-level fluctuations under greenhouse conditions remain enigmatic. This lack of understanding may be related to incoherencies in the current ideas about the impact of accelerated hydrological cycling on sea level under greenhouse climate conditions. As an example for a greenhouse climate, we review evidences that link proxies for climate and sea level for the intensely studied, but controversially discussed, mid-Cretaceous sea-level history. Based on sequence stratigraphy and a recently published high-precision timescale, we demonstrate that the late middle Turonian Pewsey delta (super 13) C isotope maximum represents a major transgression, not a regression as previously stated, which conflicts with the interpretation of a co-occurring delta (super 18) O maximum to reflect a short glacial episode. This contradiction can be solved by the concept, presented here, that dominance of aquifer-eustasy characterized sea-level forcing during the Turonian greenhouse climate, despite a possible, though contentious, sporadic presence of minor ice sheets. The effects of temperature and ice volume both lead to a pronounced delta (super 18) O (sub carb) maximum during glacio-eustatic regressions. In contrast, the opposing effects of temperature and groundwater volume on oxygen-isotope fractionation lead to a delta (super 18) O (sub carb) maximum during aquifer-eustatic transgressions. We suggest that, throughout Earth history, both aquifer-eustatic and glacio-eustatic forcing formed a combined sea-level response, with dominance of aquifer-eustasy being typical for the greenhouse climate mode. During the icehouse mode, aquifer-eustasy apparently remains active as a background process, but is outpaced by the glacio-eustatic effect. Abstract Copyright (2016) Elsevier, B.V.

In this study, based on the analyses of sedimentation, foraminifera, ostracods, bivalves, and other fossils from the Simuhana Section, as well as published biostratigraphy data, we present a field-based biostratigraphy and review of sea-level change for the Upper Cretaceous strata in the southwest Tarim Basin. The Upper Cretaceous marine strata include the Kukebai and Dongba Formations. Relatively abundant foraminifera, ostracods, and bivalves were discovered and identified. Based on the biostratigraphy and correlation, the proposed age of the lower and middle Kukebai Formation is Cenomanian to earliest Turonian; the upper Kukebai is of Turonian to early Coniacian age. The Lower Dongba Formation is late Coniacian to early Campanian, the Middle Dongba Formation is late Campanian to early Maastrichtian, and the Upper Dongba Formation is late Maastrichtian in age, possibly extending into the Danian. The relative sea level began to rise during sedimentation of the Lower Kukebai Formation (Cenomanian), and reached a maximum by the time of the middle to upper part of the Upper Kukebai Formation (Turonian to early Coniacian). After a subsequent sea level fall, another transgression began during sedimentation of the Middle Dongba Formation. Above the Upper Dongba Formation, the sea level fell dramatically. The sea level of the southwest Tarim Basin shows a close relationship with the global sea level curve, and with the sea level of south Tibet. Abstract Copyright (2016) Elsevier, B.V.

As seen elsewhere in the Tethyan domain, an overall change in facies marked by increased input of terrigenous material distinguishes the lower Aptian in the study area, but the nature of the lithologies associated with the organic carbon-rich deposits remain dominated by carbonate sediments and are expressed differently with respect to other areas where the occurrence of black shales characterizes OAE1a. This comparison indicates that significant spatial heterogeneity occurred in sub-Tethyan basins coeval with the global oceanic event. The present work provides a high-resolution, multi-proxy study (petrography, total inorganic carbon (TIC), total organic carbon TOC, carbon isotope [delta (super 13) C (sub org) ], clay mineralogy and biomarkers) of the upper 155 m of the El Pui section, Organya Basin, including the record of OAE1a. The results reveal that oxygenic conditions fluctuated throughout the studied interval, with episodes of oxygen depletion that concurred with TOC values > 1%. However, petrographic observations, molecular biomarkers, and redox sensitive trace elements (RSTEs) indicate that full anoxia was not achieved. The results also provide the first high-resolution delta (super 13) C (sub org) profile for the El Pui section that replicates in greater detail the carbon isotopic signature reported for the Tethyan domain. The upper 155 m of the El Pui section include expanded and well-defined trends of the carbon isotope segments C2 (upper part), C3, C4, C5, and C6 (partial), which correlate with other Tethyan sections and allow for the recognition of the lower Aptian OAE1a in the uppermost 40 m of the section. Such improved high-resolution chemostratigraphic curve could contribute to a more precise chronostratigraphic correlation of Aptian events in a broader scale. Abstract Copyright (2016) Elsevier, B.V.

AN - 1765876394; 2016-016606 AB - The frequency of anthropogenic seasonal hypoxia on the continental shelf west of the Mississippi Delta (the Louisiana Bight) has increased since the middle of the 20th century. This study applies the PEB index, a proxy for hypoxia, to four approximately 2 m kasten cores taken southwest of Southwest Pass of the Mississippi Delta. The PEB index is defined as the cumulative percent of Protononion atlanticum (=Nonionella atlantica of this study), Nonionella opima, Epistominella vitrea and Buliminella morgani. The PEB index varies little in the shallowest core, KC4 (59 m water depth). Assemblages were strongly dominated by PEB taxa (average 95%), due mainly to the dominance of E. vitrea (average 76%). In core KC3 (75 m), an average PEB value of 84% is also due mainly to E. vitrea (61%). The PEB index of KC3 was consistently higher above 90 cm, a level dated at 1955-1960 ( (super 210) Pb age estimate), and could reflect an increased influence of hypoxia or an increased rate of sediment accumulation associated with delta progradation. A similar trend characterizes core KC2 (87 m). The PEB index is 18% from 240 cm to 140 cm, increasing up core as the abundance of E. vitrea increases, likely due to delta progradation. Other PEB taxa, B. morgani and N. opima, increase in the top 30 cm of the core, probably due to increased hypoxia between 1952 and 1968 ( (super 210) Pb age estimate). Core KC1 (473 m) differed from shallower cores in its higher species diversity. Bolivina lowmani, Cassidulina neocarinata, and Bolivina ordinaria each comprise approximately 15% of assemblages and PEB taxa are rare (average 5%) but increase to 19% in a 30 cm interval attributed to off-shelf transport. We conclude that the PEB index is a useful indicator of anthropogenic hypoxia but dominance of E. vitrea may also be attributable to sedimentological factors related to delta progradation.

This article reviews the historical trajectory of specific facets in Western thought, including the disenchantment of nature, the apotheosis of reason, the technological domination of nature, and the Puritan temper. Illuminating this history points out that what is called "rational" and what popularly acceptable as "science" is in fact a by-product of specific historical, cultural, and political circumstances, and has produced a culture of "scientism" that is ideological, not value-free, and is in fact contrary to the open inquiry of science. These ideas are linked to economic rationality, colonialism, and human rights, severing modern humans from our Indigenous roots and fostering an ideology of rapacious environmental exploitation. The author proposes "indigeneity" as embracing the holistic knowledge and wisdom found in traditional cultures while also utilizing the advances in science and other areas of human endeavor. Specifically, the paper argues for bringing about a new cultural discourse that helps reshape human behavior into a more sustainable direction. The role of communication and storytelling is emphasized, with an example given in the story of Polynesian voyaging and the five values of the voyaging canoe.

However, patterns of abundance for large mammals, and the effects of human disturbances on them are not well understood because we lack data at the appropriate scales. We created eMammal to effectively camera-trap at landscape scale. Camera traps detect animals with infrared sensors that trigger the camera to take a photo, a sequence of photos, or a video clip. Through photography, camera traps create records of wildlife from known locations and dates, and can be set in arrays to quantify animal distribution across a landscape. This allows linkage to other distributed networks of ecological data. Through the eMammal program, we demonstrate that volunteer-based camera trapping can meet landscape scale spatial data needs, while also engaging the public in nature and science. We assert that camera surveys can be effectively scaled to a macrosystem level through citizen science, but only after solving challenges of data and volunteer management. We present study design and technology solutions for landscape scale camera trapping to effectively recruit, train and retain volunteers while providing efficient data workflows and quality control. Our initial work with > 400 volunteers across six contiguous U.S. states has proven that citizen scientists can deploy these camera traps properly (94 % of volunteer deployments correct) and tag the photos accurately for most species (67-100 %). Using these tools we processed 2.6 million images over a 2 year period. The eMammal cyberinfrastructure made it possible to process far more data than any participating researcher had previously achieved. The core components include an upload application using a standard metadata format, an expert review tool to ensure data quality, and a curated data repository. Macrosystem scale monitoring of wildlife by volunteer-run camera traps can produce the data needed to address questions concerning broadly distributed mammals, and also help to raise public awareness on the science of conservation. This scale of data will allow for linkage of large mammals to ecosystem processes now measured through national programs.

A younger origin of Metazoa would require greatly increased substitution rates across many clades and many genes; while not impossible, this is less parsimonious. Yet the first fossil evidence for metazoans (the Doushantuo embryos) about 600 Ma is followed by the Ediacaran fossils after 580 Ma, the earliest undisputed bilaterians at 555 Ma, and an increase in the size and morphologic complexity of bilaterians around 542 Ma. This temporal framework suggests a missing 150-200 Myr of early metazoan history that encompasses many apparent novelties in the early evolution of the nervous system. This span includes two major glaciations, and complex marine geochemical changes including major changes in redox and other environmental changes. One possible resolution is that animals of these still unknown Cryogenian and early Ediacaran ecosystems were relatively simple, with highly conserved developmental genes involved in cell-type specification and simple patterning. In this model, complex nervous systems are a convergent phenomenon in bilaterian clades which occurred close to the time that larger metazoans appeared in the fossil record.

AN - 1773799775; 2016-025524 AB - We report on new geoarchaeological finds in a recently discovered cave-chamber (Liang Bawah, "Cave Underneath") positioned below Liang Bua on the island of Flores, Indonesia, where the type specimen for Homo floresiensis was recovered from Late Pleistocene sediment. At the rear of Liang Bua, a 23-m-long shaft, inclined at 60 degrees , leads to a lower chamber measuring 23 m X 24 m X 5 m high (about half the size of Liang Bua). Stone artifacts and bones were found shallowly buried in rubble at the base of the shaft, and around a 5-m-high mud mound that fills the northwest sector of Liang Bawah. We recovered 17 stone artifacts made from chert and volcanics, and more than 220 well-preserved bone elements belonging to endemic giant rats, pigs, primates, small murid rodents, bats and introduced species. Multi-collector inductively coupled plasma mass spectrometer (MC-ICPMS) analysis of uranium and thorium in carbonate coatings on four bones yielded ages of approximately 240-180 ka (endemic giant rat femur), approximately 110-60 ka (unidentified phalanx), approximately 33-23 ka (pig skull fragment), and approximately 7-3 ka (giant rat femur), which overlap with the approximately 95 to 17 ka occupation of Liang Bua by H. floresiensis. The approximately 33-23 ka age of the pig skull fragment indicates that Sus sp. may have dispersed into island Southeast Asia earlier than previously recognised. The passageway at the rear of Liang Bawah, and a currently buried front entrance, represent two possible transport paths for cultural and faunal material to the cave-chamber. Analysis of the geomorphic evolution of Liang Bawah shows that it may have been a late Pleistocene depocenter for material transported from the occupation chamber of Liang Bua, and a repository for human subsistence refuse, or pit-fall trap, via the rear passage. These physical attributes, and the antiquity of the faunal remains found thus far, indicate that Liang Bawah could contain an archive of the late Pleistocene and, potentially, remains of H. floresiensis.

The level of herbivory is average for a middle Cisuralian flora from this region, although there is a relatively modest number of specimens. Three ecological features of this deposit are noteworthy in the context of the larger plant-insect interaction trends across the region. First is a well-balanced distribution across the MCF flora of the five functional feeding groups (FFGs) of external foliage feeding, piercing and sucking, oviposition, galling, and seed predation. These five FFGs encompass 22 discrete insect-mediated damage types (DTs) that indicate a variety of generalized and specialized herbivory. Second is the elevated incidence and diversity of seven gall DTs, indicating an arid environment. Third is the pattern of opportunistic herbivory on the cycadophyte Taeniopteris spp., the single, overwhelmingly dominant host that represents 47.5% of all foliage, 56.9% of all interactions, and 16 of the 22 DTs. This distribution of insect-mediated damage suggests a diverse community of opportunistic, generalized and specialized insect herbivores, including a guild of xeric-adapted gallers engaged in a variety of feeding styles that overwhelmingly targeted Taeniopteris spp. as a host plant. This characterization is consistent with an opportunistic herbivory strategy and supports Feeny's apparency hypothesis, in which the most conspicuous, accessible plant at a site is disproportionately and most extensively herbivorized.

The Skolithos Ichnofacies comprises annelid/arthropod spreite in the upper story of a fluvial channel. The Scoyenia Ichnofacies comprises tetrapod tracks, arthropleurid trackways, and shallow annelid/arthropod burrows in active/abandoned fluvial channels and rapidly aggrading levees/splays in proximal interfluve areas. The Mermia Ichnofacies comprises abundant xiphosuran trackways, along with diverse traces of other arthropods, annelids, mollusks, and fish, in shallow freshwater lakes, ponds, and coastal bays in slowly aggrading distal interfluve areas. Transitional Mermia/Scoyenia Ichnofacies comprise tetrapod, mollusk and annelid/arthropod traces in coastal bay deposits on the distal edge of the megafan. These trace fossil suites (1) provide the clearest documentation yet of the Mid-Carboniferous diversification event, when tropical continental environments became more densely populated; (2) suggest that euryhaline visitors (xiphosurans, microconchids, and other taxa) from open marine settings played a key role in this episode of freshwater colonization; and (3) provide empirical support for the "Deja vu Effect", the evolutionary concept that new or empty ecospace, recurrent in spatially and temporally variable environments, is colonized by simple ichnocoenoses.

Here we provide a redescription of Ontocetus oxymycterus, a large but incomplete fossil sperm whale specimen from the middle Miocene Monterey Formation of California, described by Remington Kellogg in 1925. The type specimen consists of a partial rostrum, both mandibles, an isolated upper rostrum fragment, and incomplete tooth fragments. Although incomplete, these remains exhibit characteristics that, when combined, set it apart morphologically from all other known physeteroids (e.g., a closed mesorostral groove, and the retention of enameled tooth crowns). Kellogg originally placed this species in the genus Ontocetus, a enigmatic tooth taxon reported from the 19th century, based on similarities between the type specimen Ontocetus emmonsi and the conspicuously large lower dentition of Ontocetus oxymycterus. However, the type of the genus Ontocetus is now known to represent a walrus tusk (belonging to fossil Odobenidae) instead of a cetacean tooth. Thus, we assign this species to the new genus Albicetus, creating the new combination of Albicetus oxymycterus, gen. nov. We provide new morphological observations of the type specimen, including a 3D model. We also calculate a total length of approximately 6 m in life, using cranial proxies of body size for physeteroids. Lastly, a phylogenetic analysis of Albicetus oxymycterus with other fossil and living Physeteroidea resolves its position as a stem physeteroid, implying that large body size and robust dentition in physeteroids evolved multiple times and in distantly related lineages.

They have dispersed and widely speciated in the North Atlantic and its tributary seas. Fucus distichus is likely near the ancestral member of this genus, and studies have shown that there are several species/subspecies in this complex (i.e. F. evanescens and F. gardneri). We used phylogenetic and haplotype analyses to test the phylogenetic relationships and biogeography of F. distichus. Our data and subsequent analyses demonstrate that, unlike previous studies that lacked samples from an extensive geographical area of the Arctic and Subarctic, there is a distinct Arctic haplotype that is the source of subspecies in both the North Pacific and North Atlantic. Fucus distichus occupies a low tide zone habitat, and in Arctic/Subarctic regions it is adapted to the severe stress of sea ice coverage and disturbance during many months per year. We hypothesize that the very large geographic area of Arctic and Subarctic rocky shores available to this species during interglacials, supported by large Arctic/Subarctic fringe areas as well as unglaciated refugia during glacial cycles, provided a robust population and gene pool (described by the Thermogeographic Model). This gene pool dilutes that of the more fragmented and area-limited Temperate/Boreal area populations when they are brought together during glacial cycles. We suggest that similar subspecies complexes for a variety of Arctic/Subarctic shore biota should be examined further in this context, rather than arbitrarily being split up into numerous species.

Analysis of the quaternary record of large magnitude explosive eruptions in Japan AN - 1861090717; 726386-16 AB - Large magnitude explosive eruptions in Japan were compiled for the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database. Here we use this dataset to investigate the under-recording of Japanese explosive eruptions. We identify under-recording of Volcanic Explosivity Index (VEI) 4-5 eruptions on two timescales. Model fitting and Akaike's information criterion (AIC and AICc) model selection suggest that these trends can be represented with the double exponential decay model, reflecting geologic processes. The time series of the recording rate of larger eruptions (VEI 6 and 7) show a slowly decreasing trend in comparison to smaller eruptions. These time series can be represented with the single exponential decay model. The percentages of missing eruptions are estimated from the fitted models. Our results show an inverse correlation between VEI and degree of under-reporting suggesting that even larger VEI eruptions are under-recorded in the Quaternary. For example, 89 % of VEI 4 events, 65-66 % of VEI 5 events, 46-49 % of VEI 6 events and 36-39 % of VEI 7 events are missing from the record at 100 ka, 200 ka, 300 ka, and 500 ka, respectively. Comparison of frequencies of Japanese and global eruptions suggests that under-recording of the global database is 7.9-8.7 times larger than in the Japanese dataset. Therefore, under-recording of events must be taken into account in estimating recurrence rates of explosive eruptions using the geologic record. Copyright 2015 The Author(s) and Kiyosugi et al.

The MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft returned a wealth of data that allow for a detailed characterization of the amount and timing of that contraction. In particular, mapping of thrust-fault-related landforms shows that the planet experienced a radius decrease of 5.1+ or -2 km since the end of heavy bombardment. Cross-cutting relationships of thrust faults with impact craters of different degradation stages indicate that global contraction operated throughout much of Mercury's past, with the earliest evidence for faulting dating from near the time of cessation of widespread plains volcanism. An assessment of the brittle strength of Mercury's lithosphere indicates that 0.4+ or -0.1 to 2.1+ or -0.4 km of radius change is necessary for stresses to be sufficiently large to overcome the frictional resistance to sliding on pre-existing fractures and faults. These values not only increase estimates for the overall amount of global contraction but also imply that this process was initiated before any evidence of shortening in the geologic record was manifest as brittle deformation. Together, these observations and results have implications for the rate at which global contraction operated through Mercury's geologic history. Higher initial strain rates are required if the radial contraction prior to the initiation of thrust faulting was approximately 2.1 km, and are possible but not required if the radial contraction accommodated prior to the onset of thrust faulting was nearly equal 0.4 km. These findings incorporate an aspect of global contraction not previously considered, as well as a contribution to radius change beyond that inferable from mapping. This approach is applicable to inferences on global contraction from tectonic mapping, and constraints on thermal histories, for any world dominated by secular cooling.

The monitoring frequency necessary to capture precursory signals at any volcano remains uncertain, as some warnings allot hours for evacuation. Likewise, no precursory signal appears deterministic for each volcano. Volcanic activity manifests in a variety of ways (i.e. tremor, deformation), thus requiring multiple monitoring mechanisms (i.e. geodetic, geochemical, geothermal). We are developing databases to compare relationships among remotely sensed volcanic unrest signals and eruptions. Satellite remote sensing utilizes frequent temporal measurements (daily to bi-weekly), an essential component of worldwide volcano monitoring. Remote sensing methods are also capable of detecting diverse precursory signals such as ground deformation from satellite interferometric synthetic aperture radar-InSAR- (multiple space agencies), degassing from satellite spectroscopy (i.e. OMI SO2 from NASA), and hot spots from thermal infrared (i.e. MODIS from NASA). We present preliminary results from seven SAR satellites and two thermal infrared satellites for 24 volcanoes with prominent SO2 emissions. We find near-continuous emissions at Ibu (Indonesia) since 2008 corresponded with hotspots and 10 cm of subsidence, with degassing and comparable subsidence observed at Pagan (Marianas). A newcomer to volcano monitoring, remote sensing data are only beginning to be utilized on a global scale, let alone as a synthesized dataset for monitoring developing eruptions. We foresee a searchable tool for rapidly accessing basic volcanic unrest characteristics for different types of volcanoes and whether or not they resulted in eruption. By including data from multiple satellite sensors in our database we hope to develop quantitative assessments for calculating the likelihood of eruption from individual events.

The Gakkel Ridge is the world's slowest spreading ridge, and exposes peridotites along its axis that record the activity of oxygen in the upper mantle. Our samples comprise relatively fertile lherzolites and harzburgites (Cr#=0.13-0.17, 3.1-8.3% modal cpx) as well as refractory harzburgites (Cr#=0.43-0.55, 0.2-1.0% modal cpx). Using spinel peridotite oxygen barometry, we calculated the oxygen fugacity (fO (sub 2) ) of a suite of 10 peridotites from the Gakkel Ridge in order to investigate how melt processes affect the oxygen budget of the Earth's interior. We show that the low-Cr# lherzolites and harzburgites range from -0.1 to +0.6 log units relative to the QFM buffer, consistent with the global abyssal peridotite array, whereas high-Cr# refractory harzburgites have low fO (sub 2) values, ranging from -0.7 to -2.7 log units below QFM, with the most refractory samples falling significantly lower than the global array. Because D'Errico et al. (submitted) interprets the refractory samples as recording ancient melt extraction, the low fO (sub 2) recorded by these samples may originate in the geologic past, perhaps even in a different tectonic setting. While LREE enrichment in the refractory harzburgites provides evidence for refertilization by an infiltrating melt that could have recently imprinted reducing conditions, we see no corresponding increase in TiO (sub 2) content in the spinels, which weakens this hypothesis. Further research on additional refractory harzburgites is needed to constrain whether the reduced nature of these samples is telling us something about the effect of extreme melt extraction on fO (sub 2) at ridges, or whether these samples record a unique history that obscures processes operating at ridges today.

Volcanics from these regions are well studied, but the forearc lithospheric mantle is less well understood, partly due to the limited number of locations with peridotite exposed in situ. The Tonga and Mariana trenches are non-accretionary convergent margins where peridotites have been collected from the wall of the over-riding plate. These forearc peridotites present a unique opportunity to study the processes associated with subduction initiation from an in-situ source. Forearc peridotites from both localities show distinct chemical heterogeneity. While all samples are extremely refractory, as evidenced by low modal abundances of clinopyroxene, they differ significantly in terms of mineral compositions and accessory phases. Minerals present in a subset of samples include plagioclase, amphibole, and sulfides. Samples also vary significantly in spinel Cr# and wt% TiO (sub 2) . We used the spinel peridotite oxygen barometer of Bryndzia and Wood (1990) to calculate the oxygen fugacity of the samples, calculating Fe (super 3+) /Sigma Fe ratio in spinels using Moessbauer-calibrated electron microprobe analysis. Samples from Mariana as well as one dredge from Tonga record elevated fO (sub 2) (1-2 log units above the QFM buffer), similar to results seen from subduction xenoliths. However, three other dredges from Tonga do not show this signature of oxidation, instead trending to high Cr# at a more ridge-like oxidation state (slightly below QFM). We interpret these non-oxidized values to be representative of primary mantle at the earliest stages of subduction, suggesting that sub-arc mantle is not oxidized prior to arc initiation. Elevated oxidation signatures then develop once this primary mantle interacts with arc-like melts and fluids related to dehydration of the subducting slab.

We used scaled experiments to investigate unsteadiness in dilute PDCs. The experimental currents were run in an 8.5X6.1X2.6 m tank and comprised heated or ambient temperature 20-mu m talc powder turbulently suspended in air. Experiments were scaled such that densimetric and thermal Richardson numbers, Froude number, and particle Stokes and settling numbers were dynamically similar to natural dilute PDCs. Although the experiment Reynolds numbers are substantially lower than those of natural PDCs, the experiments are fully turbulent. Experiments were observed with video and high-speed cameras and high-frequency thermocouples. Currents were generated with total eruption durations of 100 s. Unsteadiness in source conditions was produced by interrupting supply for intervals, t, with durations of 1, 2.5, 5, and 10 s in the experimental runs at 35 and 70 s. When t3t>tau , unsteadiness decays such that at a distance of approximately 4Ut, the currents are again steady. Applied to natural dilute PDCs, our results suggest that currents and their resulting deposits, will only show evidence of unsteadiness if they are disrupted for many seconds and those breaks may "heal" over distances of 100s of meters.

These craters have highly eroded rims and ejecta, indicating that there must be a source exposed within the crater interior that is continuously creating a rougher surface. Of particular interest are craters between 10-25 km in diameter that occur in smooth plains in the highlands, where competent layers are not expected as they are for the mare. After identifying these high-CPR interiors in pre-Copernican craters, we studied LROC NAC and Kaguya TC images to search for possible albedo and layering on crater interior walls that might signal the presence of anomalous material. Our results indicate that high-CPR craters generally have boulder fields clustered around their upper interior walls. We divide the high-CPR craters into three types: (1) craters on the layered mare lava flows; (2) craters in the highlands that correlate to mapped locations of smooth plains; and (3) craters on the highlands that are not associated with smooth plains. Most of the high-CPR craters in the highlands are associated with Eratosthenian-period craters, and most of these are also on smooth plains, indicating that impact melt sheets are a likely source for the boulders exposed on their interior walls. Statistical analyses will be performed after incorporating multiple lunar datasets into GIS to quantify these preliminary interpretations. Figure 1.

Filter pressing is inferred to play a major role in magma fractionation at shallow depths (<10 km) by moving melt and gas relative to the solid, crystalline framework. However, the magmatic conditions at which this process operates remain poorly constrained. We present novel experimental data that illustrate how the crystal content of the mush affects the ability of gas-driven filter pressing to segregate melt. Hydrous haplogranite (2.1 wt% water in the melt) and dacite (4.2 wt% water in the melt) crystal mushes, with a wide range of crystallinities (34-80 vol% crystals), were investigated using in-situ, high temperature (500-800 degrees C) synchrotron X-ray tomographic microscopy with high spatial (3 micron/pixel) and temporal resolution ( approximately 8 s per 3D data set). The experimental results show that gas-driven filter pressing operates only below the maximum packing of bubbles and crystals ( approximately 74 vol%). Above this threshold, the mush tends to fracture and gas escapes via fractures. Therefore, the efficiency of gas-driven filter pressing is promoted close to the percolation threshold and in situations where a mush inflates slowly relative to build-up of pressure and expulsion of melt. Such observations offer a likely explanation for the production of eruptible, crystal-poor magmas within Earth's crust.

The timescales between the mixing event and eruption are unknown, but reaction rims on biotite grains hosted in the Chaos Crags dacite may provide a record of the timescale (i.e., chronometer) between mixing and eruption. To quantify the effect of pre-eruptive heating on the formation of reaction rims on biotite, we conducted isobaric (150 MPa), H (sub 2) O-saturated, heating experiments on the dacite end-member. In heating experiments, we held the natural dacite at 800 degrees C and 150 MPa for 96 hours and then isobarically heated the experiments to 825 and 850 degrees C (temperatures above the biotite liquidus, <815 degrees C at 150 MPa) for durations < or =96 hours. We analyzed run products using high-resolution SEM imaging and synchrotron-based X-ray tomography, which provides a 3-dimensional rendering of biotite breakdown reaction products and textures. X-ray tomography images of experimental run products reveal that in all heating experiments, biotite breakdown occurs and reaction products include orthopyroxenes, Fe-Ti oxides, and vapor (inferred from presence of bubbles). Experiments heated to 850 degrees C for 96 h show extensive breakdown, consisting of large orthopyroxene crystals, Fe-Ti oxide laths (<100 mu m), and bubbles. When the process of biotite breakdown goes to completion, the resulting H (sub 2) O bubble comprises roughly the equivalent volume of the original biotite crystal. This observation suggests that biotite breakdown can add significant water to the melt and lead to extensive bubble formation. Although bubble expansion and magma flow may disrupt the reaction products in some magmas, our experiments suggest that biotite breakdown textures in natural samples can be used as a chronometer for pre-eruptive magma mixing.

Relative to the post Noachian craters and impact craters on the Moon and Mercury, Noachian craters generally have distinct cross-sectional profiles, with relatively flat floors and eroded rims. Craters are preserved at various stages of modification, and many larger craters are more heavily degraded than smaller ones. Furthermore, many small Noachian craters (<20-40 km in diameter) have been lost from the surface record, including nearly all Noachian craters <4 km in diameter, while larger ones were degraded to a rimless and shallow form, requiring substantial lateral erosion and infilling. This observation supports that more prolonged erosion is required than can be explained by late, short-lived events at the Noachian-Hesperian (N/H) transition. Longer-term conditions are also more relevant to biological evolutionary timescales than are shorter-term climatic excursions. We have modeled the evolution of three study sites in the Martian highlands (Noachis Terra, Terra Cimmeria, and Margaritifer Terra near Parana Valles) to constrain the erosional processes and rates that prevailed before the valley networks formed. The purpose of this study is to determine which suite(s) of geomorphic processes and rates best reproduce the relict Noachian landscape and to constrain the long-term Noachian environment through landscape evolution modeling of representative study areas in the Martian highlands. Our model runs indicate that the rate and pattern of Noachian erosion might have been limited by the weathering rate of the bedrock, if runoff production was high. When the bedrock was set to as readily erodible as regolith, crater rims retreated rapidly, causing the resulting surface topography to be largely obliterated over the model timescale. Also an arid to semiarid climate with a low dependence of runoff upon contributing area best replicates the degree of fluvial dissection and crater degradation in these regions.

Crater size-frequency analyses have shown that both deposits were emplaced around 3.8 Ga, for any of the published model production function (MPF) chronologies for impact crater formation on Mercury. The largest volcanic deposit in the southern hemisphere, the Rembrandt interior plains, has a model age of approximately 3.7 Ga. To test the hypothesis that all major volcanic smooth plains on Mercury were emplaced at about the same time, we determined crater size-frequency distributions for nine additional deposits. The diameters of craters that superpose the smooth plains at each site were measured with CraterTools, yielding crater areal densities in terms of N(10), the number of craters > or =10 km in diameter per 106 km (super 2) area. Our crater density measurements span N(10) values of 29-146, a range that encompasses corresponding values for the larger areas of smooth plains. With CraterStats, we fit our data (for craters > or =4 km in diameter) to the MPF chronologies of Le Feuvre and Wieczorek. For porous scaling, the model ages of all nine sites span a narrow window. Non-porous scaling fails to match the crater size-frequency distributions. We show that widespread plains volcanism, likely the primary process by which Mercury's crust developed, had ended by 3.6 Ga. Younger volcanic deposits have been identified on the planet, but only within impact structures and at volumes much less than the smallest deposit considered here. Superposition relations between shortening landforms and craters on Mercury indicate that global contraction in response to interior cooling was underway by approximately 3.6 Ga. The cessation of widespread plains volcanism on Mercury may therefore reflect the onset of a stress state within the planet's lithosphere that inhibited magma ascent. Conversely, mantle thermochemical evolution models indicate that magma generation may have been voluminous only until approximately 3.5 Ga.

Petrologic and experimental investigation of the mineral phases in Glass Mountain lavas may reveal differentiation processes that generated the obsidians, if the mineral assemblage is phenocrystic. Results of high-resolution SEM mapping and electron microprobe analysis of a Glass Mountain sample reveal that the obsidian is saturated in nine phases (sanidine + quartz + plagioclase + ilmenite + titanomagnetite + zircon + apatite + allanite + biotite). Sanidine (Or78-Or35) and quartz occur in the largest abundances, and plagioclase (1 Gyr year time scale.

We base our analysis on a set of about 450 direct numerical simulations of the (magneto)hydrodynamic equations under the Boussinesq approximation. The Ekman number ranges from 10-3 to 10-6. The supercriticality of the convection reaches about 1000 in some models. Four sets of simulations are considered: non-magnetic as well as dynamo simulations with either free-slip or no-slip flow boundary conditions. The hydrodynamic set-up with free-slip boundaries generates the strongest zonal flows. We then perform simulations with ingredients which would quench such shear flows: non-magnetic simulations with no-slip boundaries and self-consistent dynamos with free-slip boundaries. Both set-ups have drastically reduced zonal-flows. Suppression of zonal-flows leads to a substantial gain in heat-transfer efficiency, reaching 300% increase in some cases. Such efficiency enhancement occurs as long as the convection is significantly influenced by rotation (i.e. small enough Rossby numbers). At higher convective driving, both of these set-ups have a reduced heat-transfer efficiency. Analysis of the latitudinal distribution of heat coming out at the outer boundary reveals that the shear is most effective at suppressing heat-transfer at low-latitudes (near the equator). We also try to narrow down the influence of the magnetic field on the non-zonal flow components to test the idea of 'magnetostrophic' convection. For this purpose, the flow boundary conditions are kept no-slip and hydrodynamic simulations are compared with new self-consistent dynamo simulations. We find that even at an Ekman number of 10-5, the polar regions are already significantly affected by the presence of dynamo-generated magnetic field. Near the equator, however, only subtle changes are observed. We then run few simulations at even lower Ekman number of 10-6 and see dramatic changes in flow structure at all latitudes due to the presence of the magnetic field. Simulations at such low Ekman numbers indicate that we are approaching the magnetostrophic regime of convection.

AN - 1832723936; 2016-091847 AB - It is unknown when Earth's dynamo magnetic field originated. With crystallization ages ranging from 3.0-4.38 Ga, detrital zircon crystals found in the Jack Hills of Western Australia might preserve a record of the missing first billion years of Earth's magnetic field history. Recently, Tarduno et al. (2015) argued that magnetization in Jack Hills zircons provides evidence for a substantial geomagnetic field dating back to their U/Pb formation ages (3.3 and 4.2 Ga). However, the identification of such ancient field records requires establishing that the zircons have avoided remagnetization since their formation. At a minimum, it should be demonstrated that they have not been remagnetized since being deposited at approximately 3.0 Ga. To establish the timing and intensity of the metamorphic and alteration events experienced by the zircon, we conducted 12 paleomagnetic field tests in combination with U-Pb geochronology on their host rocks (see Weiss et al. 2015, EPSL). Our data show that the Hadean zircon-bearing rocks and surrounding region have been pervasively remagnetized, with the final major overprinting likely from emplacement of the Warakurna large igneous province at 1.1 Ga (see Figure). Even if some Jack Hills zircons do record a pre-depositional magnetization, they still could have been remagnetized sometime during the 1.4 Gy between their crystallization and their deposition. First, the temperatures capable of remagnetizing magnetite inclusions are well below those that could reset a U-Pb date or result in significant discordance. Therefore, thermal events capable of completely remagnetizing Jack Hills zircons could be undetected by the techniques reported by Tarduno at al. (2015). Second, the zircons' magnetization might be dominated by secondary ferromagnetic inclusions or contamination. To address the latter possibility, we are conducting electron microscopy, X-ray tomography, and magnetic field mapping on the zircons. Our initial quantum diamond magnetometry high-resolution (3.0 Ga) magnetization in the Jack Hills detrital zircons. We are continuing to search for such magnetic records.

Here, we review the history of debates concerning pre-historic human occupation of the Amazon Basin along with the presentation of empirical data from archaeological and palaeoecological research. The combined evidence suggests that human occupation and resulting influence on Amazonian ecosystems were heterogeneous on both regional and local scales. Pre-historic occupation sites are more likely to have been located in forests with a pronounced dry season or in forests that are within 15 km of a river floodplain, rather than in ever-wet forests or in interfluvial regions far removed from large rivers. Forest enrichment of preferred species and game depletion through hunting are most probable within 15 km of an occupation site. Given the spatial and temporal patterning of these data, views of significant Amazonian-wide cultural impacts on riverine and interfluvial forest are not supported at this time.

This investigation continues the manual documentation of ripples on Martian dunes in order to assess surface wind flow. Study sites investigated must have clear HiRISE frames and be able to represent diverse locations across the surface, decided primarily by their spread of latitude and longitude values. Additionally, frames with stereo pairs are preferred because of their ability to create digital terrain models. This will assist in efforts to relate dune slopes and obstacles to ripple patterns. The search and analysis period resulted in 40 study sites with mapped ripples. Lines were drawn perpendicular to ripple crests across three adjacent ripples in order to document both ripple wavelength from line length and inferred wind direction from azimuth. It is not possible to infer a unique wind direction from ripple orientation alone and therefore these inferred directions have a 180 degree ambiguity. Initial results from all study sites support previous observations that the Martian surface has many dune types in areas with adequate sand supply. The complexity of ripple patterns varies greatly across sites as well as within individual sites. Some areas of uniform directionality for hundreds of kilometers suggest a unimodal wind regime while overlapping patterns suggest multiple dominant winds or seasonally varying winds. In most areas, form flow related to dune shape seems to have a large effect on orientation and must be considered along with the dune type. As long as the few steep slip faces on these small dunes are avoided, form flow can be considered the dominant cause of deviation from the regional wind direction. Regional results, wind roses, and comparisons to previous work will be presented for individual sites.

In particular, the depth and sharpness of upper mantle discontinuities at 410 and 660 km depth are attributed to solid-state phase changes sensitive to both mantle temperature and composition, where regions of thermal heterogeneity produce topography and chemical heterogeneity changes the impedance contrast across the discontinuity. Seismic mapping of this topography and sharpness thus provides constraint on the thermal and compositional state of the mantle. The EarthScope USArray is providing unprecedented access to a wide variety of new regions previously undersampled by the SS precursors. This includes the boundary between the oceanic plate in the western Atlantic Ocean and continental margin of eastern North America. Here we use a seismic array approach to image the depth, sharpness, and topography of the upper mantle discontinuities, as well as other possible upper mantle reflectors beneath this region. This array approach utilizes seismic waves that reflect off the underside of a mantle discontinuity and arrive several hundred seconds prior to the SS seismic phase as precursory energy. In this study, we collected high-quality broadband data SS precursors data from shallow focus (<30 km deep), mid-Atlantic ridge earthquakes recorded by USArray seismometers in Alaska. We generated 4th root vespagrams to enhance the SS precursors and determine how they sample the mantle. Our data show detection of localized structure on the discontinuity boundaries as well as additional horizons, such as the X-discontinuity and a potential reflection from a discontinuity near the depth of the lithosphere-asthenosphere boundary. These structures are related to the transition from predominantly old ocean lithosphere to underlying continental lithosphere, as while deeper reflectors are associated with the subduction of the ancient Farallon slab. A comparison of the depth of upper mantle discontinuities to changes in seismic velocity and anisotropy will further quantify the relationship to mantle flow, compositional layering, and phases changes.

We present a comparison of radiocarbon measurements from conventional counts, atomic mass spectrometry and differing peat materials to demonstrate a general compatibility of the various types of dates. We compare and apply several summed probability distribution methods to minimize any statistical bias in our analysis. We then present our analysis of a new data set of 7571 peatland cores from 4420 sites that extend into the temperate zone. Of these, 3732 cores inform on lateral expansion and 329 dates constrain the timing of fen-bog transition. Based on these data in original and gridded form we show that widespread peat initiation commenced at 16 kcal yr BP and reached a maximum rate at 11-8 kcal yr BP. Most sites began as fens, and peak transition to bogs occurred between 5 and 3 kcal yr BP, with a 1000 year lag between Eurasia and North America. There is no global late Holocene increase in lateral expansion. Based on modeled northern peatland area and ratio of fen/bog sites, CH4 production from northern peatlands increased rapidly from 11 to 9 cal yr BP, followed by slower increase until reaching a maximum at 5 kcal yr BP at 25 Tg per yr. From 4 kcal yr BP to Present, bogs become a dominant feature in the northern peatland landscape and CH4 production decreased to reach modern-day levels at about 20 Tg per yr. Northern peatlands have been a key influence on global atmospheric methane variations but likely cannot account for the late Holocene increase in atmospheric CH4 experienced after 4 kcal yr BP.

Progressive crystallization in a dynamo-generating core is expected to play a central role in determining the observable properties of the hosted magnetic field. Importantly, the release of light elements and latent heat during core crystallization is a key source of entropy for sustaining core convection. Therefore, the persistence and intensity of a dynamo magnetic field depend directly on the extent and style of core crystallization. We present and discuss paleomagnetic data from the Earth and asteroid-sized bodies to characterize internally generated magnetic fields during the early histories of these objects. In the case of the Earth, recent and ongoing paleomagnetic experiments of zircons from the Jack Hills of Australia can potentially constrain the existence and intensity of the geodynamo before 3.5 Ga. If robust, such measurements hold strong implications for the energy budget of the Earth's early core and the dynamics of the early mantle. We will discuss both recently published and preliminary results and assess carefully the challenges and uncertainties of paleomagnetic experimentation on ancient zircon samples. In the case of small bodies, several classes of meteorites record ancient magnetic fields likely produced by core dynamos on their parent bodies. Data from the CV carbonaceous chondrites and pallasites indicate that dynamos in planetesimal-sized bodies persisted for a broad range of timescales between approximately 10 My and >100 My. Meanwhile, measurements of the angrite group of achondrites show that their earliest-forming members crystallized in an almost non-magnetic environment, suggesting a delayed onset of the planetesimal dynamo until several My after initial differentiation. We will discuss the possible causes for this observed diversity of small body dynamo properties, including the role of core crystallization and the distribution of short-lived radioisotopes.

However, Bm synthesized at 40-70 GPa contains very little Fe (super 3+) ( nearly equal 10%), indicating that charge disproportionation does not occur at depths between 1000 and 1700 km in the lower mantle. The low metallic iron layer (LMIL) can be oxidized in early Earth, because of unbalanced Fe (super 3+) and metallic iron in lower-mantle flow by core formation. The oxidizing nature of the layer may impact the siderophile element partitioning between metal and silicates if magma ocean was sufficiently deep. The layer can be further oxidized through solid mantle convection because of injection of oxidizing surface materials. The elevated oxygen fugacity will potentially make LMIL a distinct geochemical reservoir. Due to oxidizing conditions, carbon will form diamond instead of FeC in the layer. Strong partitioning of Fe (super 2+) into ferropericlase (Fp) and the low content of Fe (super 3+) in Bm will enrich Fp with iron (Fe (super +)) in LMIL. Because the Fe (super 3+) content changes gradually, the upper and lower boundaries of the layer would not produce seismically detectable discontinuities. The layer may have low thermal conductivity due to the low Fe (super 3+) content in Bm, possibly affecting dynamics of the mid mantle.

These migrations are associated with the occurrence of opposite rainfall variations between the two hemispheres. However, the pattern of rainfalls around the marine-continental tropical western Pacific region over the last millennium remains unclear. Several recent studies suggest a southward migration of the Intertropical Convergence Zone during the Little Ice Age ( approximately AD 1400-1850). Concomitantly, dry Little Ice Age conditions should have occurred in the northern extent of the Intertropical Convergence Zone and wet conditions around the southern limit. However, our synthesis of proxy hydrology records from the Asian-Australian monsoon area documents a distinctly different rainfall pattern that violates this expectation, suggesting instead the occurrence of synchronous retreat of the East Asian Summer Monsoon and the Australian Summer Monsoon during the Little Ice Age. Thus we propose an alternative dynamic scenario: rather than strict north-south migration, the apparent mode of multi-decadal to centennial change for the western Pacific Intertropical Convergence Zone is contraction/expansion in response to external forcings such as solar irradiance variation and large volcanic eruptions.

One watershed is entirely forested, one watershed is primarily agriculture with a forested stream buffer, and one watershed is mixed land use but contains a beaver produced wetland pond. Our initial goals were to assess watershed Hg yields in the mid-Atlantic and to establish a baseline prior to implementation of Hg emissions controls. All three studied watersheds produced relatively high yields of Hg, with the greatest yield coming from the forested watershed. Our initial evaluation of three watersheds showed that MeHg production and flux could also be high, but varied dramatically among watersheds and across years and seasons. During each year we observed episodic MeHg production in the spring and sometimes during prolonged high-flow storm events in the fall. The observed spring maxima of MeHg release coincided with development of anoxia in riparian groundwater. MeHg accumulation in riparian groundwater began once nitrate was depleted and either iron accumulation or sulfate depletion of groundwater began. We propose the presence of nitrate was modulating MeHg production through the suppression of sulfate and iron reducers and perhaps methanogens. As sulfate is not limiting in any of the watersheds owing to the sediments marine origin, we hypothesize the depletion of nitrate allows sulfate reducing bacteria to now utilize available carbon. Although wetlands are generally thought of as the primary zones of MeHg production in watersheds, shallow riparian groundwaters very close to the stream appear to play that role in SERC Coastal Plain watersheds. We hypothesize that the balance between nitrate, sulfate and other microbial electron acceptors in watersheds is a major control on MeHg production. Land management practices that change upset this balance by changing nitrate load and carbon quality will undoubtedly impact the cycling of Hg.

These land cover changes cause shifts in ecosystem properties and affect biosphere-atmosphere interactions. The goal of our study is to examine the effects of permafrost disappearance on landscape-scale sensible (H) and latent heat fluxes (LE) and related potential feedbacks on regional air temperatures (Ta) We use a combination of nested eddy covariance flux towers, flux footprint and planetary boundary layer (PBL) dynamic modelling, and MOderate-resolution Imaging Spectroradiometer (MODIS) remote sensing products to resolve spatio-temporal dynamics in H and LE at the landscape scale at Scotty Creek, NWT (61 degrees 18' N; 121 degrees 18' W) and in radiometric land surface temperatures (LST) at the regional scale across the southern Taiga Plains in the sporadic permafrost zone of northwestern Canada. The heterogeneous landscape comprises boreal forests with permafrost and permafrost-free wetlands. Our results show that H above the heterogeneous landscape was about twice as high as above a nearby treeless, permafrost-free bog. In contrast, landscape-scale LE was only about 50 % of LE over the bog. These differences were primarily driven by higher heat transfer efficiency of the aerodynamically rougher forest and lower albedo of the forest compared to the bog (about 10 % lower during summer and about 40 % lower during late winter). Aerodynamic LST increased with the fraction of forest in the flux footprints. This effect was strongest (r2 = 0.55, slope = 0.06 K per % forest) at the end of winter when contrasts in albedo are largest. Bulk surface conductance increased with the fraction of wetlands in the footprints. On a regional scale, radiometric MODIS LST increased with tree cover during the snow cover period (0.06 K per % tree cover), but decreased during the summer (-0.04 K per % tree cover). Modeling results showed that a shift from the current heterogeneous to a homogeneous bog landscape could lead to a decrease in the maximum PBL height by about 700 m and to a decrease in regional Ta by 1 to 2 K. Our results show clearly that permafrost degradation and forest cover shifts will affect local and regional surface energy balances in the boreal zone and could represent important modifiers of future climates.

Here a new composite record of the sea surface temperature, SST, variation in the northern South China Sea (SCS) during the late Holocene is constructed by combining seven seasonally-resolved coral and T. gigas Sr/Ca-based SST time-windows with the instrumental SST record from modern interval between 1990 and 2000. This composite multi-proxy marine record, together with the reconstructions from mainland China and tropical western Pacific, indicates that the late Holocene warm periods, the Roman Warm Period (RWP) and Medieval Warm Period (MWP), were prominently imprinted and documented in the climatic and environmental history of the East Asia-Western Pacific region. Meanwhile, substantial and significant SST seasonality variations during the late Holocene were observed in the composite record. The observed increase in seasonality (or amplitude of seasonal cycles) during the cold periods around our study area was probably caused by the different amplitudes between winter versus summer SST variations in northern SCS, with much larger SST variation during winters than during summers for the late Holocene. In addition, the distinctive warm, cold and neutral climatic episodes identified in our northern SCS composite SST record correspond well with other paleo reconstructions from mainland China and especially well with the Northern Hemisphere-wide composites by Moberg et al. (2005) and Ljungqvist (2010). The overall agreement however also calls for more information and insights on how seasonal temperatures and their ranges vary on multidecadal to bicentennial timescales.

Laboratory microcosm trials (Gilmour et al. 2013) and early field trials show that activated carbon (AC) can effectively increase partitioning of both inorganic Hg and methylmercury to the solid phase. Sediment-water partitioning can serve as a proxy for Hg and MeHg bioavailability in soils. One consideration in using AC in remediation is its potential impact on organisms. For mercury, a critical consideration is the potential impact on net MeHg accumulation and bioavailability. In this study, we specifically evaluated the impact of AC on rates of methylmercury production and degradation, and on overall microbial activity, in 4 different Hg-contaminated salt marsh soils. The study was done over 28 days in anaerobic, sulfate-reducing slurries. A double label of enriched mercury isotopes (Me199Hg and inorganic 201Hg) was used to separately follow de novo Me201Hg production and Me199Hg degradation. AC amendments decreased both methylation and demethylation rate constants relative to un-amended controls, but the impact on demethylation was stronger. The addition of 5% (dry weight) regenerated AC to soil slurries drove demethylation rate constants to nearly zero; i.e. MeHg sorption to AC almost totally blocked its degradation. The net impact was increased solid phase MeHg concentrations in some of the soil slurries with the highest methylation rate constants. However, the net impact of AC amendments was to increase MeHg (and inorganic Hg) partitioning to the soil phase and decrease concentrations in the aqueous phase. AC significantly decreased aqueous phase inorganic Hg and MeHg concentrations after 28 days. Overall, the efficacy of AC in reducing aqueous MeHg was highest in the soils with the highest MeHg concentrations. The AC addition did not significantly impact microbial activity, as assessed by CO2 production and sulfate depletion, in two of the four soils, but resulted in a up to a 40% decrease in two other soils.

However, the conditions that determine when and how magma degassing operates prior to and during an eruption remain poorly constrained. We performed experiments to explore if the initial presence of gas bubbles in magma influences the capability of gas to escape from the magma. Vesiculation of natural H (sub 2) O-poor (<<1 wt.%) silicic obsidian glasses was investigated by in situ, high-temperature (above the glass transition) experiments using synchrotron-based X-ray tomographic microscopy with high spatial (3 mu m/pixel) and temporal resolution (1 second per 3D dataset). As a validation, a second set of experiments was performed on identical starting materials using a Karl-Fisher titration setup to quantify the amount of extracted gas that escapes via volatile diffusion and/or bubble coalescence during vesiculation. In both sets of experiments, vesiculation was triggered by heating the samples at room pressure. Our results suggest that the presence of pre-existing gas bubbles during a nucleation event significantly decreases the tendency of bubbles to coalesce and inhibits magma outgassing. In contrast, in initially bubble-free samples, the nucleation and growth of bubbles is accompanied by significant coalescence and outgassing. We infer that volatile-undersaturated (i.e. bubble-free) magmas in the reservoirs are more likely to erupt effusively, while the presence of excess gas already at depth (i.e. bubble-bearing systems) increases the likelihood of explosive eruptions.

The focus of this study is to examine the spatio-temporal variation of total column CH4 over Alberta, using data from the Atmospheric Infrared Sounder (AIRS) on the EOS/Aqua satellite from 2003 to 2013. Spaceborne measurements by AIRS provide a global view of CH4 distribution in the mid-upper troposphere. This study demonstrates a significant rise of CH4 levels in Alberta in the last ten years. This ascending trend is consistent with the increase of global methane levels in the same time period. Monthly variations indicate a significant increase of CH4 levels in summer with maximum in August, which is probably driven by enhanced convection. Spatial distributions of CH4 reveal a strong west-east gradient with maximum levels in northern regions (55-65 N). The enhanced summer levels over northern and eastern regions suggest possible pathways for CH4 emitted from natural sources (wetlands, lakes and permafrost) in high northern latitude regions and Canadian wetlands (e.g. Hudson Bay wetland). However, the abrupt increase of CH4 concentration coincides with significant change in economic activities during that time period. Since some of the wetland CH4 fluxes are collocated with large anthropogenic source, it is difficult to account for different source contribution. Thus, further studies about CH4 emission and transport over Alberta are recommended to reduce the uncertainties about the natural and anthropogenic contributions of Alberta to Canada's CH4 emissions.

The area is oceanographically complex, comprising a pro-delta deep-sea fan building across a transpressional plate boundary. Outflow from the Orinoco River forms a high-productivity surface plume that abuts low-productivity water of the tropical western Atlantic Ocean across a laterally extensive but sharp front. The plume's areal extent differs between the rainy and dry seasons, which are governed by the position of the inter-tropical convergence zone (ITCZ). Upper Quaternary benthic foraminifera are examined in two approximately 4 m-long piston cores, taken near the eastern edge of the plume. CHIRP profiles show that core BGT086 (water depth 626 m) comprised in situ material throughout, while the lower part of core BGT096 (water depth 700 m) consisted of slumped material. Benthic foraminiferal assemblages in BGT086 were examined quantitatively, while those in BGT096 were examined qualitatively only for comparison. Core BGT086 shows a transition from a low-diversity, Cibicidoides pachyderma-dominated community with subdominant Cassidulina curvata to a later high-diversity, low-dominance Bulimina alazanensis-Osangularielloides rugosa-Epistominella exigua community. The former is indicative of low-productivity, and the latter of high-productivity, surface water. The restriction of E. exigua to the core's upper part may reflect a change from an aseasonal to a seasonal organic flux. The faunal change was detected by both SHE and cluster analyses and an assemblage turnover index (ATI). It may be related to either (a) expansion of the Orinoco plume due to northward migration of the ITCZ approximately 600 yr after the end of the Younger Dryas, (b) eastward progradation of the Orinoco Delta, which would in turn push the front of the Orinoco plume eastward, or (c) both. No other boundary detected was common to all three procedures. A boundary between 124 and 130 cm below the seafloor detected by SHE analysis might equate to the 8000-7500 yr BP meltwater pulse 1C. While some specialist species were restricted to the C. pachyderma or the B. alazanensis-O. rugosa-E. exigua communities, the percentage abundance of some others, concluded to be relative generalists (e.g., Bulimina aculeata and Sphaeroidina bulloides), varied little through the core. The undisturbed section of core BGT096 showed the same general faunal succession as core BGT086. The slumped material in this core was rich in Eponides regularis, which was rare elsewhere. This species shows that the allochthonous sediment was derived from the outer shelf and upper slope (100-400 m water depth) during Late Pleistocene time. Abstract Copyright (2015) Elsevier, B.V.

Previous studies indicated that conifers have lower n-alkane concentrations than angiosperms and that (super 13) C fractionation during n-alkane synthesis (epsilon (sub n-alkane) ) is smaller than in angiosperms. These prior studies, however, sampled a limited phylogenetic and geographic subset of conifers, leaving out many important subtropical and Southern Hemisphere groups that were once widespread and common components of fossil assemblages. To expand on previous work, we collected 43 conifer species (and Ginkgo biloba) from the University of California Botanical Garden at Berkeley, sampling all extant conifer families and almost two-thirds of extant genera. We find that Pinaceae, including many North American species used in previous studies, have very low or no n-alkanes. However, other conifer groups have significant concentrations of n-alkanes, especially Southern Hemisphere Araucariaceae and Podocarpaceae (monkey puzzles, Norfolk Island pines, and yellowwoods), and many species of Cupressaceae (junipers and relatives). Within the Cupressaceae, we find total n-alkane concentrations are high in subfamilies Cupressoideae and Callitroideae, but significantly lower in the early diverging taxodioid lineages (including bald cypress and redwood). Individual n-alkane chain lengths have a weak phylogenetic signal, except for n-C (sub 29) alkane, but when combined using average chain length (ACL), a strong phylogenetic signal emerges. The strong phylogenetic signal in ACL, observed in the context of a common growth environment for all plants we sampled, suggests that ACL is strongly influenced by factors other than climate. An analysis of epsilon (sub n-alkane) indicates a strong phylogenetic signal in which the smallest biosynthetic fractionation occurs in Pinaceae and the largest in Taxaceae (yews and relatives). The relationship between phylogeny and epsilon (sub n-alkane) may be related to differences in carbon metabolism among conifer clades. These results have important implications for interpreting n-alkane delta (super 13) C values in sedimentary archives, especially outside of North America. Abstract Copyright (2015) Elsevier, B.V.

Many morphological, physiological and ecological traits of trees scale with diameter, shaping the structure and function of forest ecosystems. Understanding the mechanistic basis for such scaling relationships is key to understanding forests globally and their role in Earth's changing climate system. 2. Here, we evaluate theoretical predictions for the scaling of nine variables in a mixed-age temperate deciduous forest (CTFS-ForestGEO forest dynamics plot at the Smithsonian Conservation Biology Institute, Virginia, USA) and compare observed scaling parameters to those from other forests world-wide. We examine fifteen species and various environmental conditions. 3. Structural, physiological and ecological traits of trees scaled with stem diameter in a manner that was sometimes consistent with existing theoretical predictions - more commonly with those predicting a range of scaling values than a single universal scaling value. 4. Scaling relationships were variable among species, reflecting substantive ecological differences. 5. Scaling relationships varied considerably with environmental conditions. For instance, the scaling of sap flux density varied with atmospheric moisture demand, and herbivore browsing dramatically influenced stem abundance scaling. 6. Thus, stand-level, time-averaged scaling relationships (e.g., the scaling of diameter growth) are underlain by a diversity of species-level scaling relationships that can vary substantially with fluctuating environmental conditions. In order to use scaling theory to accurately characterize forest ecosystems and predict their responses to global change, it will be critical to develop a more nuanced understanding of both the forces that constrain stand-level scaling and the complexity of scaling variation across species and environmental conditions.

Due to their pivotal role in nutrient cycling, changes in abundance of detritivores could influence the effects of elevated atmospheric CO sub(2) on essential ecosystem processes, such as decomposition and primary production. We conducted a field survey and a microcosm experiment to test the influence of changes in detritus-based food chains on litter mass loss and plant growth response to elevated atmospheric CO sub(2) using two wetland plants: a C sub(3) sedge (Scirpus olneyi) and a C sub(4) grass (Spartina patens). Our field study revealed that organism's sensitivity to climate increased with trophic level resulting in strong inter-annual variation in detritus-based food chain length. Our microcosm experiment demonstrated that increased detritivore abundance could not only enhance decomposition rates, but also enhance plant growth of S. olneyi in elevated atmospheric CO sub(2) conditions. In contrast, we found no evidence that changes in the detritus-based food chains influenced the growth of S. patens.

Soil salinity and light are known to affect mangrove performance, often in an interactive fashion. It has also been hypothesized that mangroves are intrinsically shade intolerant due to the high physiological cost of coping with saline flooded soils. To evaluate the relationship between stress tolerance and species distributions, we compared responses of seedlings of three widespread mangrove species and one narrow endemic mangrove species in a factorial array of light levels and soil salinities in an outdoor laboratory experiment. The more narrowly distributed species was expected to exhibit a lower tolerance of potentially stressful conditions. Two of the widespread species, Avicennia germinans and Lumnitzera racemosa, survived and grew well at low-medium salinity, regardless of light level, but performed poorly at high salinity, particularly under high light. The third widespread species, Rhizophora mangle, responded less to variation in light and salinity. However, at high salinity, its relative growth rate was low at every light level and none of these plants flushed leaves. As predicted, the rare species, Pelliciera rhizophorae, was the most sensitive to environmental stressors, suffering especially high mortality and reduced growth and quantum yield under the combined conditions of high light and medium-high salinity. That it only thrives under shaded conditions represents an important exception to the prevailing belief that halophytes are intrinsically constrained to be shade intolerant.

The case of Guinea-Bissau AN - 1727676282; PQ0002200395 AB - Guinea-Bissau includes large extensions of mangroves (Avicennia germinans (L.) L., Rhizophora mangle L., Laguncularia racemosa (L.) C.F. Gaertn, Conocarpus erectus L., Rhizophora racemosa G. Mey, Rhizophora harrisonii Leechm, and Machaerium lunatum (L.f.) Ducke). These wetland forests are among the most carbon (C)-rich ecosystems in the tropics, but deforestation processes may be contributing by as much as 10 % of carbon emissions from the global forest sector. Therefore, avoiding mangrove deforestation can contribute to mitigation of climate change in addition to preserving the many other vital services that these ecosystems provide. The main objective of this study is to analyze the extent to which the revenues generated by the C retained in standing mangroves can cover the cost of avoiding their clearance in Guinea-Bissau. Moreover, this study aims at demonstrating the feasibility of producing a spatially explicit national emissions baseline in a country where data, technology, and capacity are still mostly absent. It also discusses the requirements and costs of implementing the measuring, reporting and verification system needed to make C payments a reality. The analysis relies on both the quantification of C stock dynamics in mangroves and the calculation of expected returns from avoiding their clearance, given necessary investment and C prices in the market. Methodologies based on science and Earth observation technology are used to fulfil the first requirement and economic projections are applied to fulfil the second. In this paper, previously unavailable quantitative data on the deforestation trends and the biomass content of the mangroves of Guinea-Bissau are provided at national and local levels, and compared to values presented for other regions. Additionally, a national mangrove C reference emissions level (REL) is established and an assessment of the mitigation potential of mangroves, nationally and locally, is performed. The main conclusion of the analysis presented is that, if the price of avoided carbon dioxide (CO sub(2)) emissions is above the United State Dollars (USD) 6.69 to USD 7.20/t range, and governance risk can be contained, it is possible to delineate cost-effective activities to avoid deforestation of mangroves and promote climate change mitigation activities in Guinea-Bissau using C revenues alone.

The assumption is that holding solution pH constant does not serve as the primary control for the variety of Mn oxide produced. To test this assumption, synthetic triclinic Na-birnessite was reacted in batch experiments with a pH 7 HEPES buffer, a pH 7 MES buffer, and an unbuffered pH 7 solution for 14 days in total darkness. At the end of the experimental run, the Mn oxide solids were analyzed by conventional and synchrotron X-ray powder diffraction. These assays revealed that in the presence of the HEPES buffer, triclinic Na-birnessite completely transformed into highly crystalline hexagonal H-birnessite. In unbuffered solutions starting at pH 7 and in the presence of MES, which offers a lower buffering capacity than does HEPES, triclinic Na-birnessite partially transformed to poorly crystalline hexagonal H-birnessite. The unbuffered pH 7 solution exhibited an increase in pH to 8.03. We interpret the results to indicate that: 1) buffers can indirectly promote the transformation of triclinic Na-birnessite to hexagonal H-birnessite by serving as a source of H (super +) , even at circumneutral pH; 2) triclinic Na-birnessite alone can stimulate hydrolysis, which in turn induces an exchange of H (super +) for interlayer Na (super +) ; and 3) H-birnessite and Na-birnessite operate as an acid-conjugate base pair.

To maximize inclusive fitness, reciprocal food sharing should occur among close kin. Why then do females with kin roost-mates help non-kin? We tested the hypothesis that helping non-kin increases a bat's success at obtaining future donations by expanding its network of potential donors. On six occasions, we individually fasted 14 adult females and measured donations from 28 possible donors. Each female was fasted before, during and after a treatment period, when we prevented donations from past donors (including 10 close relatives) by simultaneously fasting or removing them. This experiment was designed to detect partner switching and yielded three main results. First, females received less food when we prevented donations from a past donor versus a control bat. Donors within a group are therefore not interchangeable. Second, the treatment increased the variance in donors' contributions to food received by subjects, suggesting the possibility of alternative responses to a partner's inability to reciprocate. Finally, bats that fed more non-kin in previous years had more donors and received more food during the treatment. These results indicate that a bat can expand its network of possible donors by helping non-kin.

These interferometers are designed to detect the mergers of compact object binaries composed of neutron stars and/or black holes to a fiducial distance of ~200 Mpc and a localization region of ~100 deg[sup 2]. To maximize the science gains from such GW detections it is essential to identify electromagnetic counterparts. Here we present detailed simulated observations that encompass a range of strategies for kilonova searches during GW follow-up. Motivated by the results of our simulations we discuss the expected performance of current and future wide-field telescopes in achieving these observational goals, and find that prior to LSST the Dark Energy Camera on the Blanco 4 m telescope and Hyper Suprime-Cam on the Subaru 8 m telescope offer the best potential for kilonova discovery.

AN - 1722418091; 26320568 AB - In a previous study of female Han/Wistar (H/W) and Long-Evans (L-E) rats, we found that adult exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) was associated with size decreases in the cranium and especially the face. In this study we compared these crania to those from male and female Sprague-Dawley (S-D) rats with in utero/lactational exposure to TCDD, using morphometric variables of size, shape, and fluctuating asymmetry to quantify the effects of dose on craniofacial development and growth. At the highest levels of exposure, in utero/lactational and adult TCDD exposures both resulted in small but significant reductions in facial size parameters (i.e., 3-5%) in only females and minor effects on facial shape in both sexes. The shape effects of in utero/lactational exposure were most significant at the sutural intersections, whereas adult exposure to TCDD corresponded to dose-dependent changes of decreasing facial length and vault breadth. Fluctuating asymmetry in general explained a relatively small amount of shape variation compared with other effects, and only increased significantly in female L-E rats with high levels of adult exposure to TCDD. These results indicate that TCDD-related changes in cranial development and growth in rats can vary with the timing and duration of exposure, and with sex. Further investigations of other dioxin-like compounds and animal species will broaden our understanding of how chemicals exposure can influence the development and growth of the mammalian skeleton.

We investigated the contribution of different litter tissues from two peatland tree species (Raphia taedigera and Campnosperma panamensis) to peat formation in four lowland tropical peatlands in the Republic of Panama. Leaves, stems, and roots decomposed at different rates; with roots being the slowest to decompose among tissues. The position of litter in the peat profile strongly influenced the decomposition rate of all tissue types. Roots decomposed up to five times faster at the surface than at 50 cm depth. Molecular characterization of litter and peat profiles by tetramethylammonium-pyrolysis-gas chromatography-mass spectrometry (TMAH-Py-GC/MS) revealed that the peat is formed predominantly of decomposed roots and stems, as indicated by the high lignin, low methylated fatty acids and carbohydrate concentrations in these litter types. Taken together, these data demonstrate that roots play a fundamental role in the formation of lowland Neotropical peatlands.

Their formation is primarily attributed to the accommodation of horizontal shortening of Mercury's lithosphere in response to cooling and contraction of the planet's interior. Analyses of images acquired by the Mariner 10 and MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft during flybys of Mercury showed that thrust faults were active at least as far back in time as near the end of emplacement of the largest expanses of smooth plains. However, the full temporal extent of thrust fault activity on Mercury, particularly the duration of this activity following smooth plains emplacement, remained poorly constrained. Orbital images from the MESSENGER spacecraft reveal previously unrecognized stratigraphic relations between lobate scarps and impact craters of differing ages and degradation states. Analysis of these stratigraphic relations indicates that contraction has been a widespread and long-lived process on the surface of Mercury. Thrust fault activity had initiated by a time near the end of the late heavy bombardment of the inner solar system and continued through much or all of Mercury's subsequent history. Such deformation likely resulted from the continuing secular cooling of Mercury's interior. Abstract Copyright (2015), . American Geophysical Union. All Rights Reserved.

Little is known about similar processes in invertebrates. Invertebrate and vertebrate fossils were analyzed for REE concentrations and patterns from five Miocene formations in central Panama ( approximately 20-6 m.yr.ago). These formations (Culebra, Cucaracha, Gatun, Chucunaque, and Chagres) contain sediments interpreted to range from freshwater to shallow marine environments (depth of <300 m). We also compared different compositional types of fossils, including hydroxylapatite (bone) and aragonite (otoliths) in vertebrates and calcite and aragonite in invertebrates. REEs from modern invertebrates indicate that, as previously reported for vertebrates, invertebrates do not incorporate significant amounts of REEs into their mineral lattices during life, therefore, uptake must primarily occur during diagenesis. Comparisons of REE (sub N) concentrations (REE concentrations normalized to Post-Archean Australian Shale) of the fossils from Panama indicate differences in diagenesis. Within our largest sample from the Gatun Formation, there are significance differences in REE (sub N) concentrations and patterns within different compositional types. For example, shark teeth have the highest REE (sub N) concentrations and otoliths the lowest, with these differences likely a result of physical, chemical, and mineralogical factors. Calcitic and aragonitic fossils from the Gatun Formation show REE (sub N) patterns indicating differential uptake of individual elements during diagenesis. The cerium anomaly, previously used to indicate relative paleobathymetry, did not discriminate water depth in the marine formations. Comparative analysis of REEs in vertebrates and invertebrates provides a powerful tool to understand diagenetic processes, as demonstrated in the five formations and different compositional types studied from the Miocene of Panama.

Published Tanzanian oxygen isotope records measured on exquisitely preserved foraminiferal tests, dating to as old as ~93Ma, provided evidence for a Turonian "hot greenhouse" with very high and stable water-column temperatures. We have generated a comparable data set of exceptionally well-preserved foraminifera from a lower Cenomanian interval of TDP Site 24 spanning 99.9-95.9Ma (planktonic foraminiferal Thalmanninella globotruncanoides Zone; nannofossil Corollithion kennedyi to Lithraphidites eccentricus Zones), thereby extending the age coverage of the Tanzanian foraminiferal delta super(18)O record back by ~7 million years. Throughout the interval analyzed, the new foraminiferal delta super(18)O data are consistently around -4.3ppt for surface-dwelling planktonic taxa and -1.9ppt for benthic Lenticulina spp., which translate to conservative paleotemperature estimates of >31 degree C at the surface and >17 degree C at the sea floor (upper bathyal depths). Considering the ~40 degree S Cenomanian paleolatitude of TDP Site 24, these estimates are higher than computer simulation results for accepted "normal" greenhouse conditions (those with up to 4X preindustrial pCO sub(2) level) and suggest that the climate mode of the early Cenomanian was very similar to the Turonian hot greenhouse. Taking account of other comparable data sources from different regions, the hot greenhouse mode within the normal mid-Cretaceous greenhouse may have begun by the latest Albian, but the precise timing of the critical transition remains uncertain. Key Points * Exquisitely preserved fossil foraminifera are obtained through the Tanzania Drilling Project * Examined cores at Site 24 are biochronologically dated 99.9-95.9Ma (early Cenomanian) * Foraminiferal isotopic temperatures indicate a "hot greenhouse" mode during the mid-Cretaceous JF - Paleoceanography AU - Ando, Atsushi AU - Huber, Brian T AU - MacLeod, Kenneth G AU - Watkins, David K AD - Department of Paleobiology, National Museum of Natural History, Smithsonian Institution, Washington, Dist. of Columbia, USA.

In this paper, we consider two factors which may have contributed to this controversy: 1. Several different solar variability datasets exist. While each of these datasets is constructed on plausible grounds, they often imply contradictory estimates for the trends in solar activity since the 19th century. 2. Although attempts have been made to account for non-climatic biases in previous estimates of surface air temperature trends, recent research by two of the authors has shown that current estimates are likely still affected by non-climatic biases, particularly urbanization bias. With these points in mind, we first review the debate over solar variability. We summarise the points of general agreement between most groups and the aspects which still remain controversial. We discuss possible future research which may help resolve the controversy of these aspects. Then, in order to account for the problem of urbanization bias, we compile a new estimate of Northern Hemisphere surface air temperature trends since 1881, using records from predominantly rural stations in the monthly Global Historical Climatology Network dataset. Like previous weather station-based estimates, our new estimate suggests that surface air temperatures warmed during the 1880s-1940s and 1980s-2000s. However, this new estimate suggests these two warming periods were separated by a pronounced cooling period during the 1950s-1970s and that the relative warmth of the mid-20th century warm period was comparable to the recent warm period. We then compare our weather station-based temperature trend estimate to several other independent estimates. This new record is found to be consistent with estimates of Northern Hemisphere Sea Surface Temperature (SST) trends, as well as temperature proxy-based estimates derived from glacier length records and from tree ring widths. However, the multi-model means of the recent Coupled Model Intercomparison Project Phase 5 (CMIP5) climate model hindcasts were unable to adequately reproduce the new estimate - although the modelling of certain volcanic eruptions did seem to be reasonably well reproduced. Finally, we compare our new composite to one of the solar variability datasets not considered by the CMIP5 climate models, i.e., Scafetta and Willson, 2014's update to the Hoyt and Schatten, 1993 dataset. A strong correlation is found between these two datasets, implying that solar variability has been the dominant influence on Northern Hemisphere temperature trends since at least 1881. We discuss the significance of this apparent correlation, and its implications for previous studies which have instead suggested that increasing atmospheric carbon dioxide has been the dominant influence.

They aid in reef accretion and stabilization, create habitat for other organisms, contribute to carbon sequestration and are important settlement substrata for a number of marine invertebrates. Despite their ecological importance, little is known about the bacterial communities associated with CCA or whether differences in bacterial assemblages may have ecological implications. This study examined the bacterial communities on four different species of CCA collected in Belize using bacterial tag-encoded FLX amplicon pyrosequencing of the V1-V3 region of the 16S rDNA. CCA were dominated by Alphaproteobacteria, Gammaproteobacteria and Actinomycetes. At the operational taxonomic unit (OTU) level, each CCA species had a unique bacterial community that was significantly different from all other CCA species. Hydrolithon boergesenii and Titanoderma prototypum, CCA species that facilitate larval settlement in multiple corals, had higher abundances of OTUs related to bacteria that inhibit the growth and/or biofilm formation of coral pathogens. Fewer coral larvae settle on the surfaces of Paragoniolithon solubile and Porolithon pachydermum. These CCA species had higher abundances of OTUs related to known coral pathogens and cyanobacteria. Coral larvae may be able to use the observed differences in bacterial community composition on CCA species to assess the suitability of these substrata for settlement and selectively settle on CCA species that contain beneficial bacteria.

This is only the second marine interval found in the entire Pennsylvanian fill of the Maritimes Basin of Canada, the other being recently found in the broadly same-age Joggins Formation of Nova Scotia. Evidence for the new marine transgression comprises an echinoderm-rich limestone that infills irregularities on a vertic paleosol surface within the distal facies of a syntectonic fluvial megafan formed under a seasonally dry tropical climate. Gray, platy ostracod-rich shales and wave-rippled sandstone beds that directly overlie the marine limestone contain trace fossils characteristic of the Mermia Ichnofacies, upright woody trees, and adpressed megafloras. This association represents bay-fills fringed by freshwater coastal forests dominated by pteridosperms, cordaites, and other enigmatic plants traditionally attributed to dryland/upland habitats. The fossil site demonstrates that marine transgressions extended farther into the interior of Pangea than has previously been documented, and may allow correlation of the Tynemouth Creek and Joggins Formations with broadly coeval European successions near the level of the Gastrioceras subcrenatum and G. listeri marine bands. It also helps explain the close similarity of faunas between the Maritimes Basin and other paleotropical basins, if transgressions facilitated migration of marine taxa into the continental interior.

Most common among isolates from upper Oligocene deposits of Jamaica and Antigua are marginal ossicles of an extinct, indeterminate species of Pycinaster. This is the youngest known occurrence of the genus and the first from beyond Europe. A number of relatively complete fossils have been assigned to Pycinaster and (sub)familial status proposed for it together with Phocidaster. The latter proposition is based solely on a few marginals, but available diagnoses are judged insufficient to justify such recognition. The taxon Pycinasteridae is here synonymized with the Goniasteridae, although future study of added features (such as the ventral surface) might justify recognition at a higher taxonomic level. In addition to ossicles assigned to Pycinaster, many marginals are tentatively assigned to the surviving goniasterid Nymphaster. Numerous generic and many species names have been based on asteroid isolates, but the practice demands assumptions that are not readily justified. Linkage of discrete isolates under a single taxon name assumes derivation from a single source, an inference that can be verified only rarely (if ever), therefore reducing names to the single holotype ossicle. Availability of only isolates encourages comparison with extant taxa and biogeography, biasing interpretations with a Holocene overlay. Because of these constraints, a new nominal species of Pycinaster is not justified and assignment of ossicles to Nymphaster is tentative. However, given the importance of asteroids in marine communities, we emphasize the significance, largely ignored, of their presence in Cenozoic deposits of the wider Caribbean.

These findings raised questions concerning a possible speciation event in P.rhizophorae , for which a series of macro- and microscopic morphological traits (reproductive and vegetative structures), molecular markers from plastid DNA and climatic profiles were analyzed. Samples of P.rhizophorae were collected in three localities from the Panamanian Caribbean and Pacific coasts. The data obtained from molecular markers and morphological traits showed significant differences between the variants. The climatic profiles showed contrasting characteristics of rainfall and temperature in their habitats: variant A is found in wetter zones and variant B occupies drier zones. Evidence suggesting that a process of incipient speciation has occurred in P.rhizophorae in response to ecogeographical isolation due to climatic factors is presented. The presence of two geographically separate genetic-morphological groups, adapted to contrasting climatic conditions, will be the basis for suggesting the existence of incipient lineages in Pelliciera . copyright 2015 The Linnean Society of London, Botanical Journal of the Linnean Society, 2015, 179, 499-510.

The blue crab Callinectes sapidus in the South Atlantic Bight (SAB), USA, inhabits estuaries ranging from large semi-enclosed bays to narrow river mouths where estuarine conditions extend onto the continental shelf. Mature female reproductive status was used as an indicator to identify spawning habitat, and data from long-term fishery independent surveys were used to evaluate spatiotemporal trends in abundance of spawning females. Long-term data (1990-2011) were obtained from the Southeast Area Marine Assessment Program (SEAMAP) South Atlantic survey and the Georgia Ecological Monitoring Trawl Survey. Biological samples were obtained from estuarine and offshore areas of Georgia for a detailed analysis of habitat use. Reproductive status of mature female blue crabs (ovigery, ovary development, egg remnants) was indicative of a summer peak in spawning in Georgia that occurred primarily on the continental shelf as far as 13 km offshore. SEAMAP data provide strong evidence that blue crab females spawn on the continental shelf throughout the SAB, with substantial declines in spawner abundance over time. Empirical orthogonal function analysis of SEAMAP time series was indicative of regional spawning areas defined by biogeography which are poorly aligned with fishery management jurisdictions. Indicators of reproductive status provided a powerful method for identifying spawning habitats of an estuarine migrant species, especially when spawners may disperse over the continental shelf and occur at low density.

Based on images obtained by the Curiosity rover, we interpret these outcrops as evidence for past fluvial, deltaic, and lacustrine environments. Degradation of the crater wall and rim probably supplied these sediments, which advanced inward from the wall, infilling both the crater and an internal lake basin to a thickness of at least 75 meters. This intracrater lake system probably existed intermittently for thousands to millions of years, implying a relatively wet climate that supplied moisture to the crater rim and transported sediment via streams into the lake basin. The deposits in Gale crater were then exhumed, probably by wind-driven erosion, creating Aeolis Mons (Mount Sharp).

A mid-twentieth century boundary level is stratigraphically optimal AN - 1832616585; 762455-14 AB - We evaluate the boundary of the Anthropocene geological time interval as an epoch, since it is useful to have a consistent temporal definition for this increasingly used unit, whether the presently informal term is eventually formalized or not. Of the three main levels suggested - an 'early Anthropocene' level some thousands of years ago; the beginning of the Industrial Revolution at approximately 1800 CE (Common Era); and the 'Great Acceleration' of the mid-twentieth century - current evidence suggests that the last of these has the most pronounced and globally synchronous signal. A boundary at this time need not have a Global Boundary Stratotype Section and Point (GSSP or 'golden spike') but can be defined by a Global Standard Stratigraphic Age (GSSA), i.e. a point in time of the human calendar. We propose an appropriate boundary level here to be the time of the world's first nuclear bomb explosion, on July 16th 1945 at Alamogordo, New Mexico; additional bombs were detonated at the average rate of one every 9.6 days until 1988 with attendant worldwide fallout easily identifiable in the chemostratigraphic record. Hence, Anthropocene deposits would be those that may include the globally distributed primary artificial radionuclide signal, while also being recognized using a wide range of other stratigraphic criteria. This suggestion for the Holocene-Anthropocene boundary may ultimately be superseded, as the Anthropocene is only in its early phases, but it should remain practical and effective for use by at least the current generation of scientists.

Twenty-four adult morphological characters were scored for the three species in the "Megaxylocopa clade" plus 10 outgroup taxa from subgenus Neoxylocopa Michener. Xylocopa (Xylocopoides) virginica (Linnaeus) was used as a distant outgroup taxon to root the tree. A single most parsimonious tree was recovered by cladistic analysis using the computer software program TNT. The three species of the "Megaxylocopa clade" form a well-supported monophyletic group that is the sister-lineage of another monophyletic group that includes the other 10 species of subgenus Neoxylocopa. Within the "Megaxylocopa clade," Xylocopa nautlana Cockerell and X. frontalis (Olivier) are sister-species, relative to X. fimbriata Fabricius.

We show that the sporangia dehisced into more or less equal valves through a mechanism that involved the development of large thick-walled cells. Furthermore the coalified xylem is composed of tracheids with G-type thickenings (predominantly annular secondary thickenings with small circular to irregular perforations in the intervening wall), confirming the presence of this form of vascular element in the genus Zosterophyllum. The species diagnosis is emended. Characterisation of dehiscence mechanisms in fossil sporangia is complicated by their different modes of preservation. A brief critical survey of the marginal features in bivalved sporangia in zosterophylls and other selected species is followed by a discussion on their putative functional significance. Preservation notwithstanding, we identify clear differences in mechanisms related to the nature of the underlying cellular structure of the dehiscence feature. The distinctive groove present in many species might represent a mechanism for regulating the timing of dehiscence in response to atmospheric conditions. Abstract Copyright (2015) Elsevier, B.V.

Temporal observations of a linear dune located in the Simpson Desert of central Australia were made to monitor dune movement and to test competing hypotheses regarding linear dune formation. Our observations were collected on three separate occasions from 2006 to 2014. Rebar stakes were placed in a gridded pattern so that multiple measurements of sand thickness, GPS surveys, and photographs could be taken at the same locations over time. We observed widespread reworking of sand on and around the dune crest, with sand accumulation locally exceeding a meter between surveys. Overall, the height of the dune crest increased by several centimeters. We also observed fluctuations in the sand cover in the adjacent swales that often exceeded 2-3 cm between surveys, yet we did not observe any appreciable changes in the position of the dune's downwind terminus. Weather data indicate that the effective sand-transporting winds in the Simpson are widely unimodal. Net sediment flux (resultant drift direction) is toward the north-northwest, locally at an oblique angle to dune orientation. Collectively, our results suggest that the linear dune is actively maintained by vertical accretion. The implications from our observations are that linear dunes on other planetary surfaces could form in wind regimes that are widely unimodal, even where the resultant drift direction is locally oblique to dune orientation. In particular, such findings may provide support for global circulation models of Titan. Abstract Copyright (2015), . American Geophysical Union. All Rights Reserved.

We propose a new method that addresses these limitations. We illustrate this method with data from southwestern Gabon (central Africa). We used stratified random transect surveys conducted in two seasons to model the distribution of African forest elephant (Loxodonta cyclotis), forest buffalo (Syncerus caffer nanus), and sitatunga (Tragelaphus spekii) in a mosaic landscape along a 38.5 km unpaved road scheduled for paving. Using a validation data set of recorded crossing locations, we evaluated the performance of three types of models in predicting actual road crossings for each species, and developed a unique and flexible scoring method for prioritizing road sections for the implementation of road fragmentation mitigation measures. This approach improves upon available methods and can help inform prioritization of road and other linear infrastructure segments that require impact mitigation methods to ensure long-term landscape connectivity.

It was found as rare fragments up to approximately 60 mu m across in one of the grains (labeled number 126) of the Khatyrka meteorite, a CV3 carbonaceous chondrite. The meteoritic grain contains evidence of a heterogeneous distribution of pressures and temperatures that occurred during impact shock, in which some portions of the meteorite reached at least 5 GPa and 1200 degrees C. Decagonite is associated with Al-bearing trevorite, diopside, forsterite, ahrensite, clinoenstatite, nepheline, coesite, pentlandite, Cu-bearing troilite, icosahedrite, khatyrkite, taenite, Al-bearing taenite, and steinhardtite. Given the exceedingly small size of decagonite, it was not possible to determine most of the physical properties for the mineral. A mean of seven electron microprobe analyses (obtained from three different fragments) gave the formula Al (sub 70.2(3)) Ni (sub 24.5(4)) Fe (sub 5.3(2)) , on the basis of 100 atoms. A combined TEM and single-crystal X-ray diffraction study revealed the unmistakable signature of a decagonal quasicrystal: a pattern of sharp peaks arranged in straight lines with 10-fold symmetry together with periodic patterns taken perpendicular to the 10-fold direction. For quasicrystals, by definition, the structure is not reducible to a single three-dimensional unit cell, so neither cell parameters nor Z can be given. The likely space group is P10 (sub 5) /mmc, as is the case for synthetic Al (sub 71) Ni (sub 24) Fe (sub 5) . The five strongest powder-diffraction lines [d in Aa (I/I (sub 0) )] are: 2.024 (100), 3.765 (50), 2.051 (45), 3.405 (40), 1.9799 (40). The new mineral has been approved by the IMA-NMNC Commission (IMA2015-017) and named decagonite for the 10-fold symmetry of its structure. The finding of a second natural quasicrystal informs the longstanding debate about the stability and robustness of quasicrystals among condensed matter physicists and demonstrates that mineralogy can continue to surprise us and have a strong impact on other disciplines.

Based on their small scale and crisp appearance, crosscutting relations with small-diameter impact craters, and rates of infilling of associated small, shallow graben, these fault scarps are estimated to be younger than 50 Ma and may be actively forming today. The non-random distribution of the scarp orientations is inconsistent with isotropic stresses from late-stage global contraction as the sole source of stress. We propose that tidal stresses contribute significantly to the current stress state of the lunar crust. Orbital recession stresses superimposed on stresses from global contraction with the addition of diurnal tidal stresses result in non-isotropic compressional stress and thrust faults consistent with lobate scarp orientations. The addition of diurnal tidal stresses at apogee result in peak stresses that may help trigger coseismic slip events on currently active thrust faults on the Moon.

The samples exhibit little to no postentry oxidation via Mossbauer and Raman spectroscopy indicating their fresh character, but despite the rapid collection and care of handling some low levels of terrestrial contamination did nonetheless result. Detailed studies show three distinct lithologies, indicative of a genomict breccia. A light-colored lithology is LL5 material that has experienced thermal metamorphism and subsequent shock at levels near S4. The second lithology is a shock-darkened LL5 material in which the darkening is caused by melt and metal-troilite veins along grain boundaries. The third lithology is an impact melt breccia that formed at high temperatures ( approximately 1600 degrees C), and it experienced rapid cooling and degassing of S (sub 2) gas. Portions of light and dark lithologies from Chel-101, and the impact melt breccias (Chel-102 and Chel-103) were prepared and analyzed for Rb-Sr, Sm-Nd, and Ar-Ar dating. When combined with results from other studies and chronometers, at least eight impact events (e.g., approximately 4.53 Ga, approximately 4.45 Ga, approximately 3.73 Ga, approximately 2.81 Ga, approximately 1.46 Ga, approximately 852 Ma, approximately 312 Ma, and approximately 27 Ma) are clearly identified for Chelyabinsk, indicating a complex history of impacts and heating events. Finally, noble gases yield young cosmic ray exposure ages, near 1 Ma. These young ages, together with the absence of measurable cosmogenic derived Sm and Cr, indicate that Chelyabinsk may have been derived from a recent breakup event on an NEO of LL chondrite composition.

Raw data suggest that marine metazoans diversified dramatically during the late Mesozoic and Cenozoic, whereas bias-corrected analyses based on occurrence-level data in the Paleobiology Database (PBDB) have indicated much less Cenozoic diversification. These standardized analyses are cited as evidence that biases strongly conceal underlying patterns in the global fossil record. However, we show that marine diversity did increase substantially and continuously from the Jurassic to the Neogene, even after correcting for biases in PBDB data. Previous standardized analyses did not capture this diversification in full because they were based on incomplete data. In the Cenozoic, observed richness rose to twice the Paleozoic average, which is within the range of values seen in analyses of raw data, suggesting that even the raw global marine fossil record preserves first-order signals of diversity history.

AN - 1717489588; PQ0001959781 AB - The key components of crassulacean acid metabolism (CAM) - nocturnal fixation of atmospheric CO sub(2) and its processing via Rubisco in the subsequent light period - are now reasonably well understood in terms of the biochemical reactions defining this water-saving mode of carbon assimilation. Phenotypically, however, the degree to which plants engage in the CAM cycle relative to regular C sub(3) photosynthesis is highly variable. Depending upon species, ontogeny and environment, the contribution of nocturnal CO sub(2) fixation to 24-h carbon gain can range continuously from close to 0% to 100%. Nevertheless, not all possible combinations of light and dark CO sub(2) fixation appear equally common. Large-scale surveys of carbon-isotope ratios typically show a strongly bimodal frequency distribution, with relatively few intermediate values. Recent research has revealed that many species capable of low-level CAM activity are nested within the peak of C sub(3)-type isotope signatures. While questions remain concerning the adaptive significance of dark CO sub(2) fixation in such species, plants with low-level CAM should prove valuable models for investigating the discrete changes in genetic architecture and gene expression that have enabled the evolutionary transition from C sub(3) to CAM.

Our results reveal an emplacement history consisting of multiple groups of overlapping lava flow units, originating from different sources. The uniquely complex "radar stratigraphy" of Elysium Planitia, relative to other volcanic regions, requires a distinct mechanism to generate the numerous reflectors observed in SHARAD data. Sedimentary deposits interbedded with successive batches of lava flows could account for the elaborate pattern of reflectors. We infer that widespread, rapidly emplaced material sourced from the enigmatic Medusae Fossae Formation (MFF) creates these sedimentary layers. This implies that episodes of atmospheric activity, perhaps linked with the obliquity of Mars, periodically erode and redeposit material from the MFF across a large region.

Textured dust storms predominantly occur in the equinox seasons while both solstice periods experience a planet-wide "pause" in textured dust storm activity. These pauses correspond to concurrent decreases in global atmospheric dust opacity. Textured dust storms most frequently occur in Acidalia Planitia, Chryse Planitia, Arcadia Planitia, and Hellas basin. To examine the nature of the link between textured dust storms and atmospheric dust opacity, we compare the textured dust storm climatology with a record of atmospheric dust opacity and find a peak global correlation coefficient of approximately 0.5 with a lag of 20-40 degrees in solar longitude in the opacity compared to the solar climatology. This implies that textured dust storms observed at 1400 local time by MOC are responsible for a large fraction of atmospheric dust opacity and that other mechanisms (e.g., dust devil lifting or storm-scale lifting not observed in this study) may supply a comparable amount of dust.

As in the case of the Moon, the origin of early plains deposits has been difficult to determine because ponded impact basin ejecta and impact melt deposits can mimic the topography and texture of extrusive volcanic plains. In order to understand better the role that impact basins play in resurfacing on Mercury, we used MESSENGER Mercury Dual Imaging System (MDIS) data to map the distribution of plains deposits within and around the relatively young Rembrandt impact basin ( approximately 720 km in diameter). There are two different Rembrandt plains units: (1) high-reflectance interior and exterior plains, and (2) low-reflectance exterior plains. The morphology, crater size-frequency distribution, and N(20) crater density values were analyzed for each deposit. Observations of the two high-reflectance plains deposits are consistent with previous studies of volcanically produced smooth plains on Mercury. The low-reflectance exterior plains are older than the other high-reflectance plains and comparable in age to the Rembrandt basin impact event. On the basis of age, areal distribution, and albedo relationships with basin materials, the low-reflectance plains are interpreted as basin impact melt deposits. The large areal extent of the low-reflectance plains suggests that basin impact melt deposits may have played an important role in resurfacing Mercury, especially during the early geologic history of the planet when impact rates were higher.

This re-examination revealed new information on the morphology of this taxon, including previously unknown parts of the skeleton such as the palate, braincase, and shoulder girdle. Elachistosuchus is diagnosed especially by the presence of the posterolateral process of the frontal, the extension of the maxillary tooth row to the posterior margin of the orbit, the free posterior process of the jugal, and the notched anterior margin of the interclavicle. Phylogenetic analyses using two recently published character-taxon matrices recovered conflicting results for the phylogenetic position of Elachistosuchus-either as an archosauromorph, as a lepidosauromorph or as a more basal, non-saurian diapsid. These different placements highlight the need of a thorough revision of critical taxa and new character sets used for inferring neodiapsid relationships.

These displays can provide multimodal cues that aid predators, but the benefits in attending to them should depend on the environmental sensory conditions under which they forage. We assessed whether bats hunting for frogs use multimodal cues to locate their prey and whether their use varies with ambient conditions. We used a robotic set-up mimicking the sexual display of a male toungara frog (Physalaemus pustulosus) to test prey assessment by fringe-lipped bats (Trachops cirrhosus). These predatory bats primarily use sound of the frog's call to find their prey, but the bats also use echolocation cues returning from the frog's dynamically moving vocal sac. In the first experiment, we show that multimodal cues affect attack behaviour: bats made narrower flank attack angles on multimodal trials compared with unimodal trials during which they could only rely on the sound of the frog. In the second experiment, we explored the bat's use of prey cues in an acoustically more complex environment. Touungara frogs often form mixed-species choruses with other frogs, including the hourglass frog (Dendropsophus ebraccatus). Using a multi-speaker set-up, we tested bat approaches and attacks on the robofrog under three different levels of acoustic complexity: no calling D. ebraccatus males, two calling D. ebraccatus males and five D. ebraccatus males. We found that bats are more directional in their approach to the robofrog when more D. ebraccatus males were calling. Thus, bats seemed to benefit more from multimodal cues when confronted with increased levels of acoustic complexity in their foraging environments. Our data have important consequences for our understanding of the evolution of multimodal sexual displays as they reveal how environmental conditions can alter the natural selection pressures acting on them.

This paper investigates the historical inflection point when humans began to control animals not only as alimental resources but as ritual symbols and social actors in the New World. At Teotihuacan (A.D. 1-550), one of the largest pre-Hispanic cities, animal remains were integral components of ritual caches expressing state ideology and militarism during the construction of the Moon and the Sun Pyramids. The caches contain the remains of nearly 200 carnivorous animals, human sacrificial victims and other symbolic artifacts. This paper argues the presence of skeletal pathologies of infectious disease and injuries manifest on the carnivore remains show direct evidence of captivity. Stable isotope analysis (delta (super 13) C and delta (super 15) N) of bones and teeth confirms that some of these carnivores were consuming high levels of C (sub 4) foods, likely reflecting a maize-based anthropocentric food chain. These results push back the antiquity of keeping captive carnivores for ritualistic purposes nearly 1000 years before the Spanish conquistadors described Moctezuma's zoo at the Aztec capital. Mirroring these documents the results indicate a select group of carnivores at Teotihuacan may have been fed maize-eating omnivores, such as dogs and humans. Unlike historical records, the present study provides the earliest and direct archaeological evidence for this practice in Mesoamerica. It also represents the first systematic isotopic exploration of a population of archaeological eagles (n = 24) and felids (n = 29).

Newly discovered fossils from the late Arikareean Lirio Norte Local Fauna, Panama Canal basin, include partial dentitions of a protoceratid remarkably similar to those of Paratoceras tedfordi from Mexico, suggesting a rapid early Miocene colonization of recently emerged tropical volcanic terrains (Las Cascadas Formation). Partial lower dentitions from the overlying shallow marine to transitional Culebra Formation (early Centenario Fauna) are here referred to Paratoceras orarius, sp. nov., based on relatively small size, shallow mandible anterior to p3, and narrow cheek teeth. New early Hemingfordian protoceratine fossils from the upper part of the Cucaracha Formation (late Centenario Fauna) include a partial male skull and several dentitions that, together with specimens previously referred to P. wardi (only known from the Barstovian of Texas), are here referred to Paratoceras coatesi, sp. nov., based on distinctly more gracile cranial ornamentation, relatively longer nasals, a smaller and wider lower p4 (relative to m1), and more bulbous lower premolars. Results from a cladistic analysis of 15 craniodental characters coded for 11 protoceratine species suggests that Paratoceras is a monophyletic clade with its origin in subtropical areas of Central America, spreading into the tropics of Panama during the early Miocene (Arikareean through Hemingfordian North American Land Mammal Ages [NALMAs]), and later inhabiting subtropical areas of the Gulf Coast during the middle?late Miocene (Barstovian through Clarendonian NALMAs).

Study of this material shows that it is not a distinct species but rather an interstratified nickel-bearing lizardite-clinochlore, with lizardite dominant over clinochlore. The name "maufite" is discredited. The lizardite is a Group-A polytype, and the clinochlore is a Ia polytype in the nomenclature developed by S.W. Bailey. The formula calculated on the basis of 14 negative charges is (Mg (sub 1.74) Al (sub 0.88) Ni (sub 0.13) (sub 0.25) ) (sub Sigma 3.00) (Si (sub 1.60) Al (sub 0.40) ) (sub Sigma 2.00) O (sub 5) (OH) (sub 4) ; on the basis of nine oxygen atoms including 14.6 wt.% H (sub 2) O determined thermogravimetrically, the formula is (Mg (sub 1.68) Al (sub 0.78) Ni (sub 0.13) (sub 0.41) ) (sub Sigma 3.00) (Si (sub 1.55) Al (sub 0.45) ) (sub Sigma 2.00) O (sub 4.51) (OH) (sub 4.49) Analytical electron microscopy shows that the composition is variable on a fine scale. The randomly interstratified lizardite-clinochlore occurs as a pseudomorph after amphibole and plagioclase and is a product of serpentinization. The material is poorly crystalline and very fine grained, producing broad reflections on powder diffraction and microbeam X-ray diffraction patterns. Unlike most of the interstratified serpentine-chlorite described in the literature, lizardite is here dominant over clinochlore.

As the first line of defence, the taxonomically conserved acute phase immune reaction of leucocytosis and fever is crucial for coping with infections, but it is unknown if this response is a key constituent to bat immunological success. We investigated the acute phase reaction to a standard lipopolysaccharide (LPS) challenge in Pallas's mastiff bats (Molossus molossus). Challenged bats lost mass, but in contrast to other mammals showed no leucocytosis or fever. There also was no influence on body temperature reduction during torpor. When compared to recent genome-wide assays for constituent immune genes, this lack of a conserved fever response to LPS contributes to a clearer understanding of the innate immune system in bat species and of the coevolution of bats with a wide diversity of pathogens.

Specialist species have narrower fundamental niches than do generalists. Thus, specialists benefit from homogeneous environments while generalists can exploit heterogeneous ones. The challenge is distinguishing relative specialists from generalists in a sedimentary rock succession. This is overcome by taking replicate samples from several horizons in a heterogeneous formation and comparing species' mean percentage abundances using analysis of variance (ANOVA). The mean proportional abundances of specialists will differ between horizons in a heterogeneous succession, while those of generalists will not. The Globorotalia fohsi robusta Zone Middle Miocene Cipero Formation of Trinidad, western central Atlantic Ocean, consists of alternating, diffuse layers of light to dark grey clays. Five replicates of 40 g each were taken from four horizons across a light- to dark-grey cycle. They were picked entirely clean of benthic foraminifera, of which they yielded 5186 specimens in 153 species. Total recovery was dominated by Brizalina cf. tectiformis, with lesser Globocassidulina subglobosa, Pleurostomella alazanensis and Planulina wuellerstorfi. ANOVA applied to each species in turn indicated three species groups: 64 accessory species (each represented by < or = 3 specimens, < or = 0.06% of total recovery); 21 specialist species, for which mean percentage abundance varied significantly between at least two horizons; and 68 generalist species, for which mean percentage abundances did not differ across the horizons. It might be thought that ANOVA would preferentially assign a specialist status to less abundant species. However, this did not happen; of the four most abundant species, P. alazanensis was a specialist, while B. cf. tectiformis, G. subglobosa and P. wuellerstorfi were generalists. The mean percentage abundance of the specialist species did not differ from that of the generalists. Both specialist and generalist species have palaeoenvironmental applications. The generalist nature of P. wuellerstorfi shows that bottom current strength probably did not differ across the four horizons. The occurrence of the specialist and opportunistic Epistominella exigua in the lowest horizon indicates an interlude of seasonal phytodetrital flux, while sequential increases in the mean percentage abundance of the specialists Oridorsalis umbonatus and Uvigerina auberiana show that the organic carbon flux increased across the four horizons.

Mean modal abundances and abundance ranges of pyroxene, olivine, and mesostasis vary widely among different thin-sections of an individual nakhlite. Lithologic heterogeneity is the main factor contributing to the observed modal-abundance variations measured in thin-sections prepared from different fragments of the same stone. Two groups of nakhlites are distinguished from one another by which major constituent varies the least and the abundance of that constituent. The group consisting of Nakhla, Lafayette, Governador Valadares, and the Yamato nakhlite pairing group is characterized by low modal mesostasis and pyroxene-olivine covariance, whereas the group consisting of the Miller Range nakhlite pairing group and Northwest Africa 5790 is characterized by low modal olivine and pyroxene-mesostasis covariance. These two groups sample the slowest-cooled interior portion and the chilled margin, respectively, of the nakhlite emplacement body as presently understood, and appear to be also related to recently proposed nakhlite groups independently established using compositional rather than petrographic observations. Phenocryst modal abundances vary with inferred depth in the nakhlite igneous body in a manner consistent with solidification of the nakhlite stack from dynamically sorted phenocryst-rich magmatic crystal-liquid mush.

Relative to typical type A and B CAIs found elsewhere, the bulk compositions of the types A and B CAIs within 3N more closely match the bulk compositions predicted by equilibrium condensation of a gas of solar composition. Being trapped within the FoB melt may have protected them from melt evaporation that affected most "stand-alone" CAIs. 3N originated either as an aggregate of many smaller (mostly types A, B, C) CAIs plus accreted Fo-bearing material (like an amoeboid olivine aggregate) which experienced partial melting of the whole, or else as a FoB melt droplet that collided with and trapped many smaller solid CAIs. In the former case, 3N recorded the earliest accretion of pebble-sized bodies known. In the latter case, the presence of a large number of individual refractory inclusions within 3N suggests a very high local density of refractory solids in the immediate region of the host CAI during the brief time while it was melted. Collisions would have occurred on time scales of hours at most, assuming a melt solidification interval for the host CAI of 300-400 degrees C (maximum) and a cooling rate of nearly equal 10 degrees C/h.

Arthropod prey strongly influence habitat-specific persistence of long-distance migrant passerines in their wintering areas, and arthropods are strongly affected by rainfall. However, the effect of drought on the dynamics of avian foraging ecology as resources shift is not well understood. We captured female American Redstarts (Setophaga ruticilla) and studied their foraging behavior in high-quality (evergreen black mangrove) and low-quality (deciduous scrub) habitat in Jamaica during the winter of 1995-1996. As is typical in southwestern Jamaica, conditions became drier as spring approached and many trees in scrub lost most of their leaves; mangrove trees maintained most of their leaf cover. Birds in scrub lost more mass than those in mangrove, and scrub birds shifted to using more aerial (and fewer near-perch) maneuvers. In scrub, but not in mangrove, the proportion of wing-powered movements and aerial foraging maneuvers was positively correlated with mass corrected by body size. In both habitats, attack rate was negatively correlated with body condition. Therefore, redstarts in scrub that maintained body condition were likely better able to use energetically expensive aerial maneuvers and wing-powered search movements to exploit large, calorie-rich flying arthropods. As the scrub dried over the course of the winter, the shift in foraging tactic may have allowed some birds to forage more efficiently (i.e., lower attack rate), likely facilitating maintenance of good body condition.

In the equatorial regions of Pangea, the response of terrestrial ecosystems was highly variable geographically, reflecting the interactions of polar ice and geographic patterns on atmospheric circulation. In general, however, there was a drying trend throughout most of the western and central equatorial belt. In western Pangea, the climate proved to be considerably more seasonally dry and with much lower mean annual rainfall than in areas in the more central and easterly portions of the supercontinent. Here we describe lower Permian (upper Asselian) fossil plant assemblages from the Community Pit Formation in Prehistoric Trackways National Monument near Las Cruces, south-central New Mexico, U.S.A. The fossils occur in sediments within a 140-m-wide channel that was incised into indurated marine carbonates. The channel filling can be divided into three phases. A basal channel, limestone conglomerate facies contains allochthonous trunks of walchian conifers. A middle channel fill is composed of micritic limestone beds containing a brackish-to-marine fauna with carbon, oxygen and strontium isotopic composition that provide independent support for salinity inferences. The middle limestone also contains a (par)autochthonous adpressed megaflora co-dominated by voltzian conifers and the callipterid Lodevia oxydata. The upper portions of the channel are filled with muddy, gypsiferous limestone that lacks plant fossils. This is the geologically oldest occurrence of voltzian conifers. It also is the westernmost occurrence of L. oxydata, a rare callipterid known only from the Pennsylvanian-Permian transition in Poland, the Appalachian Basin and New Mexico. The presence of in situ fine roots within these channel-fill limestone beds and the taphonomic constraints on the incorporation of aerial plant remains into a lime mudstone indicate that the channel sediments were periodically colonized by plants, which suggests that these species were tolerant of salinity, making these plants one of, if not the earliest unambiguous mangroves.

Vismione B (1), deacetylvismione A (2), and deacetylvismione H (3) are cytotoxic compounds isolated from V. baccifera. Compound 1 was found in the 2nd and 3rd instars of P. arcaei, but not in the mature larvae or the pupae. Pyrrhopyge thericles assimilated trace quantities of compound 1 and deacetylvismione A (2), which were both found in the 3rd and 4th instars. In extracts of V. baccifera, compound 2 is present at levels approximately 6-fold greater than compound 1, indicating that the generalist P. arcaei is capable of selectively sequestering cytotoxic compounds from its host plant. Compounds 1 and 2 show comparable cytotoxicities in three different cancer cell lines, suggesting that properties other than cytotoxicity are responsible for the selective sequestration of 1 by P. arcaei. This study represents the first time that sequestration of this class of compounds has been recorded in the Lepidoptera.

AN - 1718053282; 2015-094013 AB - The lower bathyal Ocean Drilling Program Hole 1261A was sampled near an upper Quaternary oxygen minimum zone (OMZ). Glauconite, the percentage of the foraminiferal assemblage as benthic specimens and assemblage composition were used to investigate the behaviour of the OMZ. Benthic foraminifera and glauconite were comparable with the upper margin of the modern OMZ off California. The percentage abundances of U. peregrina and C. laevigata were on the Demerara Rise negatively correlated, the proportional abundance of U. peregrina increasing upwards through the section. This reflects variations in proximity to the upper margin of the OMZ. This might reflect either crustal subsidence or long-term shallowing of the OMZ during the earlier late Quaternary. Neither hypothesis can be accepted unequivocally. The purported subsidence can be ascribed to crustal loading by the Amazon and Orinoco deep-sea fans, but this would require that the palaeodepth to the top of the OMZ remains constant across several glacial-interglacial cycles. In contrast, it is difficult to envisage any mechanism that could have caused progressive shallowing of the OMZ across several glacial-interglacial cycles. The epifaunal Planulina wuellerstorfi is related to more oxic waters and enhanced current action. This suggests that intervals with more abundant P. wuellerstorfi were somewhat less dysoxic than those with few. These intervals approximate to those with more abundant C. laevigata. Superimposed on this low-frequency signal is a higher-frequency signal, indicated by a between-sample assemblage turnover index (ATI (sub s) ) that might prove useful for long-range sequence stratigraphic correlation at bathyal depths.

Contrary to expectations, female Cercopithecus mitis form linear dominance hierarchies without evidence for rank-related variation in fitness-relevant measures, raising questions about the evolution of guenon social structure. Here, we test whether social status predicts gastrointestinal helminth infections, known to influence health and morbidity in other mammalian hosts. In addition, we assess whether infections contribute to stress responses as indicated by fecal glucocorticoid (fGC) levels. We quantified infections and hormone levels in 382 fecal samples from 11 adult female Sykes' monkeys (C. m. albogularis) over four months in one wild study group at Gede Ruins, Kenya. Using a generalized estimating equations technique, we modeled the odds of infection, relative infection intensity, and fGC variation. High-ranking females were less likely infected with Trichuris and Trichostrongylus, had lower fecal egg counts for both taxa, and overall lower helminth richness than low‐ ;ranking females. An inverse relationship between rank and Trichuris egg counts existed also in a study population of blue monkeys (C. m. stuhlmanni), where we collected comparable data over a shorter period. Regardless of rank, lactating females were more likely than non-lactating females to be infected with Trichuris, and had higher fecal egg counts for both Trichuris and Oesophagostomum. Lastly, we report evidence that Trichuris infections exacerbated energetic stress and that food supplementation by tourists increased infection levels. Our findings suggest that high‐ ;rank may provide long-term health and energetic benefits for female C. mitis, with potential fitness implications.

Its status as one of the rarest songbirds in North America has been attributed to the scarcity of breeding and wintering habitat. Although the warbler was once thought to be a habitat specialist of lowland canebrakes, it is now known to breed in a wide spectrum of broadleaf forest habitats linked by the common denominator of high stem densities and visual screening in the understorey stratum. Scattered instances of a fundamental habitat expansion into early seral stages of even-aged pine plantations were first observed in east Texas in 1992. Here I report that the colonisation of pine plantations is not only locally extensive in Texas but that it is widespread on the coastal plain eastward to south-eastern Virginia. During two decades of field surveys, breeding territories (n = 297) were documented in young pine plantations in 95 counties and parishes in 10 states. Occupied plantations were mostly 6-12 m tall (median = 7.5 m), corresponding to 8-15 years after planting. Soil type and the presence of interspersed broadleaf vegetation may be important co-factors in plantation occupancy. The chronology of this breeding niche expansion is poorly known but it appears to have occurred after the 1970s, most likely catalysed by the rapid growth of pine plantation silviculture after World War II. As late as 2001, it was believed that > 90% of the breeding population occurred in broadleaf floodplain forest. The recent range-wide colonisation of pine plantations changes the calculus. If the current trend continues, forest lands managed for short-rotation pine plantations will support the majority of breeding populations by the end of the 21 super(st) century.

Here, two alternative and antithetical explanatory frameworks for initial domestication are comparedDLone based on diet breadth modeling and the other on niche construction theory. This side-by-side comparison of these two alternative explanations follows them through the basic sequence of stages involved in the scientific method: hypothesis formulation, plausibility consideration, and actual testing of the two hypothetical explanations by measuring their relative strengths with the available archaeological and paleoenvironmental data from two independent centers of domestication in the AmericasDLeastern North America and the Neotropics. Although focused on the question of initial domestication, this comparative analysis also addresses the broader issues of the appropriate role of theory in the development of hypotheses of past human behavior and the proper use of the scientific method in archaeological inference. Explanations based on diet breadth modeling are found to have a number of conceptual, theoretical, and methodological flaws; approaches based on niche construction theory are far better supported by the available evidence in the two regions considered.

Gyaclavator can be placed within the Tingidae with certainty, perhaps it is sistergroup to Cantacaderinae. If it belongs to Cantacaderinae, it is the first fossil record of this group for North America. Gyaclavator has unique, conspicuous antennae bearing a specialized, highly dilated distiflagellomere, likely important for intra- or intersex reproductive competition and attraction. This character parallels similar antennae in leaf-footed bugs (Coreidae), and probably is associated with a behavioral convergence as well.

Filter pressing is inferred to play a major role in magma fractionation at shallow depths (<10 km) by moving melt and gas relative to the solid, crystalline framework. However, the magmatic conditions at which this process operates remain poorly constrained. We present novel experimental data that illustrate how the crystal content of the mush affects the ability of gas-driven filter pressing to segregate melt. Hydrous haplogranite (2.1 wt% water in the melt) and dacite (4.2 wt% water in the melt) crystal mushes, with a wide range of crystallinities (34-80 vol% crystals), were investigated using in-situ, high-temperature (500-800 degree C) synchrotron X-ray tomographic microscopy with high spatial (3 mu m/pixel) and temporal resolution ( similar to 8 s per three-dimensional data set). Our experimental results show that gas-driven filter pressing operates only below the maximum packing of bubbles and crystals ( similar to 74 vol%). Above this threshold, the mush tends to fracture and gas escapes via fractures. Therefore, the efficiency of gas-driven filter pressing is promoted close to the percolation threshold and in situations where a mush inflates slowly relative to build-up of pressure and expulsion of melt.

Using the bulk chemistry data set, we determine four gamma-ray/neutron parameters in the HEDs (1) relative fast neutron counts (fast counts), (2) macroscopic thermal neutron absorption cross section (absorption), (3) a high-energy gamma-ray compositional parameter (C (sub p) ), and (4) Fe abundance. These correspond to the four measurements of Vesta made by Dawn's Gamma Ray and Neutron Detector (GRaND) that can be used to discern HED lithologic variability on the Vestan surface. We investigate covariance between fast counts and average atomic mass () in the meteorite data set, where a strong correlation (r (super 2) = 0.99) is observed, and we demonstrate that systematic offsets from the fast count/ trend are linked to changes in Fe and Ni concentrations. To compare the meteorite and GRaND data, we investigate and report covariance among fast counts, absorption, C (sub p) , and Fe abundance in the HED meteorite data set. We identify several GRaND measurement spaces where the Yamato type B diogenites are distinct from all other HED lithologies, including polymict mixtures. The type B's are diogenites that are enriched in Fe + pigeonite + diopside + or - plagioclase, relative to typical, orthopyroxenitic diogenites. We then compare these results to GRaND data and demonstrate that regions north of approximately 70 degrees N latitude on Vesta (including the north pole) are consistent with type B diogenites. We propose two models to explain type B diogenite compositions in the north (1) deposition as Rheasilvia ejecta, or (2) type B plutons that were emplaced at shallow depths in the north polar region and sampled by local impacts. Lastly, using principal component (PC) analysis, we identify unique PC spaces for all HED lithologies, indicating that the corresponding GRaND measurables may be used to produce comprehensive lithologic maps for Vesta.

Yet, the time scales over which oxygen fugacity of the mantle wedge changes during subduction initiation and margin evolution are unknown. Fe speciation ratios show that magmas produced during the early stages of subduction in the Mariana arc record oxygen fugacities approximately 2X more oxidized than MORB. Mantle wedge oxygen fugacity rises by approximately 1.3 orders of magnitude as slab fluids become more involved in melt generation processes, reaching conditions essentially equivalent to the modern arc in just 2-4 m.y. These results constrain existing models for the geochemical evolution of the mantle wedge and suggest that oxidation commences upon subduction initiation and matures rapidly in the portions of the mantle wedge that produce melts. This further implies that sulfide or other reduced phases are not present in the mantle wedge in high enough abundance to prevent oxidation of the magmas that form upon subduction initiation. The arc mantle source is oxidized for the majority of a subduction zone's lifetime, influencing the mobility of multivalent elements during recycling, the degassing of oxidized volcanic volatiles, and the mechanisms for generating continental crust from the immediate onset of subduction.

This information is needed for parametrizing models that can inform management and conservation. Here, we use 14 years of data on colour-marked birds to investigate how conspecific density and habitat quality during the tropical non-breeding period interact to affect body condition and apparent annual survival of a long-distance migratory songbird, the American redstart (Setophaga ruticilla). Body condition and survival of birds in high-quality mangrove habitat declined as density increased. By contrast, body condition improved and survival did not vary as density increased in adjacent, lower quality scrub habitat, although mean condition and survival were almost always lower than in mangrove. High rainfall enhanced body condition in scrub but not in mangrove, suggesting factors such as food availability outweighed consequences of crowding in lower quality habitat. Thus, survival of overwintering redstarts in mangrove habitat, disproportionately males, appears to be regulated by a crowding mechanism based on density-dependent resource competition. Survival of individuals in scrub, mostly females, appears to be limited by density-independent environmental factors but not regulated by crowding. The contrasting effects of density and food limitation on individuals overwintering in adjacent habitats illustrate the complexity of processes operating during the non-breeding period for migratory animals, and emphasize the need for long-term studies of animals in multiple habitats and throughout their annual cycles.

While the ring inner radius coincides with the CO snow line, it is not apparent why N (sub 2) H (super +) is abundant outside the CO snow line in spite of the similar sublimation temperatures of CO and N (sub 2) . Using the full gas-grain network model, we reproduced the N (sub 2) H (super +) ring in a disk model with millimeter grains. The chemical conversion of CO and N (sub 2) to less volatile species (sink effect hereinafter) is found to affect the N (sub 2) H (super +) distribution. Since the efficiency of the sink depends on various parameters such as activation barriers of grain-surface reactions, which are not well constrained, we also constructed the no-sink model; the total (gas and ice) CO and N (sub 2) abundances are set constant, and their gaseous abundances are given by the balance between adsorption and desorption. Abundances of molecular ions in the no-sink model are calculated by analytical formulae, which are derived by analyzing the full-network model. The N (sub 2) H (super +) ring is reproduced by the no-sink model, as well. The 2D (R-Z) distribution of N (sub 2) H (super +) , however, is different among the full-network model and no-sink model. The column density of N (sub 2) H (super +) in the no-sink model depends sensitively on the desorption rate of CO and N (sub 2) and the cosmic-ray flux. We also found that N (sub 2) H (super +) abundance can peak at the temperature slightly below the CO sublimation, even if the desorption energies of CO and N (sub 2) are the same.

Specialists from various disciplines have focused on the packaging of information to generate new evolutionary individuals, on the expansion of ecological opportunity, or the abiotic drivers of environmental change to which organisms respond as the major drivers of these episodes. But the critical issue for understanding these major evolutionary transitions (METs) lies in the interactions between environmental, ecologic, and genetic change. Here, I propose that public goods may serve as one currency of such interactions: biological products that are non-excludable and non-rivalrous. Such biological public goods may be involved in either the generation of new evolutionary variation, as with genetic sequences that are easily transferred between different microbial lineages, or in the construction of new ecological niches, as with the progressive oxygenation of the oceans and atmosphere. Attention to public goods emphasizes the processes by which organisms actively construct their own evolutionary opportunities. Such public goods may have facilitated some METs.

It is unknown to what degree the remaining forest, which is fragmented and subject to poaching, still supports the wildlife diversity found in intact forests. Here, we use camera-trap surveys to assess whether forests in Central Panama, the narrowest and most disturbed portion of the Isthmus, still have intact communities of medium- and large-bodied terrestrial mammals. During 2005-2014, we collected camera-trap survey data from 15 national parks and forest fragments on both sides of the Panama Canal, and compared these to similar data from two sites in the intact Darien National Park in Eastern Panama, the nearest available reference. We found that most sites in Central Panama - including some of the national parks - had lower mammal species richness and evenness than the reference sites, and less structurally-complex mammal communities. Forests in Central Panama had little or no apex predators and large terrestrial frugivores, with the exception of two sites directly connected to the reference site. Our results indicate that the terrestrial mammal community in forests of Central Panama is currently degraded, even inside national parks. These data provide a baseline for evaluating the success of conservation efforts to prevent the Panamanian Isthmus to become a bottleneck for movement of animals.

L., is described. D. crambidoides occurs in the southern United States and Mexico and is an economic pest of corn (Zea mays L.). It has been reported to also feed on sorghum (Sorghum bicolor (L.) Moench), johnsongrass (Sorghum halepense (L.) Persoon), and sugar cane (Saccharum officinarum L.). We confirm that D. crambidoides also feeds on eastern gama grass. Morphological and molecular characters support the status of D. mitteri as a new species. Parsimony analysis resulted in two clades corresponding to D. crambidoides and D. mitteri. We confirm the distribution of D. mitteri from Kansas, Oklahoma, and Texas, but its distribution could be as broad as the remaining range of eastern gama grass in the eastern United States. All the life stages are described and illustrated. A novel host association, Alabagrus imitatus Cresson (Hymenoptera: Braconidae), as a parasitoid of D. mitteri is reported.

Anatahan (Mariana Islands) is a remote volcano in the western North Pacific. Available ground-based measurements of sulphur dioxide (SO sub(2)) gas emissions at Anatahan place it among thelargest volcanic SO sub(2) sources worldwide. These ground-based measurements, however, are restricted to eruptive intervals. Anatahan's activity since 2003 has been dominated temporally by prolonged periods of quiescence. Using 10years of satellite observations from OMI, AIRS, SCIAMACHY, and GOME-2, we report highly variable SO sub(2) emissions within and between eruptive and quiescent intervals at Anatahan. We find close correspondence between levels of activity reported at the volcano and levels of SO sub(2) emissions detected from space. Eruptive SO sub(2) emission rates have a mean value of 6400td super(-1), but frequently are in excess of 20,000td super(-1). Conversely, SO sub(2) emissions during quiescent intervals are below the detection limit of space-based sensors and therefore are not likely to exceed 300td super(-1). We show that while Anatahan occupies a quiescent state for 85% of the past 10years, only 15% of total SO sub(2) emissions over this interval occur during quiescence, with the remaining 85% released in short duration but intense syn-eruptive degassing. We propose that the integration of multiyear satellite data sets and activity histories are a powerful complement to targeted ground-based campaign measurements in better describing the long-term degassing behavior of remote volcanoes. Key Points * SO sub(2) emissions at Anatahan vary widely between eruptive and quiescent states * Satellite observations are key to establishing long-term trends in gas emissions * Eighty-five percent of total SO sub(2) emissions from Anatahan during 2004-2015 were syn-eruptive JF - Journal of Geophysical Research: Atmospheres AU - McCormick, Brendan AU - Popp, Christoph AU - Andrews, Benjamin AU - Cottrell, Elizabeth AD - Department of Mineral Sciences, Smithsonian Institution, National Museum of Natural History, Washington, District of Columbia, USA.

Here we report two chondrichthyan assemblages that include 30 taxa from both the Rio Indio and Chagres Sandstone Members of the Chagres Formation. We report 18 new fossil records for Panama and four for tropical America, constituting the most diverse chondrichthyan association for the Cenozoic of Panama. We performed a paleobathymetry analysis based on the modern water depth preference of extant chondrichthyan taxa. The assemblage from the Rio Indio Member is characterized by taxa with neritic affinities, suggesting depths <100 m, whereas the assemblage from the Chagres Sandstone Member is dominated by taxa with oceanic affinities, suggesting 200-300 m water depths. The Chagres Sandstone Member could have accumulated at the edge of a platform-upper slope, bordered by a deep oceanic margin. Abstract Copyright (2015) Elsevier, B.V.

Three possible mechanisms other than vegetation could contribute to the bank cohesion required to promote meandering: permafrost, abundant mud, and chemical cementation. Banks at the meandering Quinn River show little vegetation cover. Almost all sediment samples collected from the Quinn River deposits contain at least 41% mud (silt/clay), which is much higher than for most meandering streams. Ion chromatography (IC) analysis and scanning electron microscope (SEM) images showed presence of salts in river waters and sediments which may induce fine sediment to flocculate and be deposited. We find that bank cohesion promoting meandering can be provided by silt/clay, the deposition of which may be induced by dissolved salts. The sinuous Usuktuk River in the continuous permafrost region near Barrow, Alaska exhibited no exposed permafrost on stream banks. Instead vegetation seemed to be the dominant control of bank erosion. We have not found evidence for ice control of bank cohesion in this or other terrestrial rivers of similar size and in meandering pattern to the Martian AD meanders. We conclude that bank cohesion in the AD meanders was probably provided by deposition of fine suspended sediment that was flocculated by dissolved salts. Abstract Copyright (2015) Elsevier, B.V.

The meandering inverted paleochannels and closed drainage basin of this deposit support relatively well constrained estimates of channel-forming discharge (over an individual event flood timescale), runoff production (event and annual timescales), and longevity of deposition (geologic timescale) during the Late Hesperian to Early Amazonian Epochs. The width and meander dimensions of two inverted paleochannels reflect the channel-forming discharge from event floods ( approximately 200 to 400 m (super 3) /s), the deposit surface indicates the level (- 1400 to - 1350 m) and surface area (410 to 810 km (super 2) ) of the likely paleolake, and the topography and mapped extent of tributaries constrain the watershed area (5000 to 17,000 km (super 2) ). Based on these results and terrestrial empirical constraints on evaporation and sediment concentration, we evaluated three hypothetical water sources: meltwater liberated by the nearby Holden crater impact (continuous deposition over approximately 10 (super 1) -10 (super 2) years), intermittent rainfall or snowmelt during finite periods controlled by orbital evolution (deposition over approximately 10 (super 4) -10 (super 6) years), and highly infrequent runoff or melting of accumulated snowpacks following distant impacts or secular changes in orbital parameters. Local impact-generated runoff and highly infrequent rainfall or snowmelt require unreasonably high and low rates of evaporation, respectively, to maintain the paleolake level. The local impact hypothesis alternatively depends on one flooding episode with very high concentrations of fluvial sediment that are inconsistent with morphologic considerations. Multiple primary impact craters in the area postdate Holden ejecta but were later dissected, indicating fluvial erosion long after the Holden impact. Intermittent rainfall of approximately 1 cm/day and seasonal snowmelt are both consistent with our results over a deposition timescale totaling approximately 10 (super 4) -10 (super 6) years.

Here we compare the modern non-passerine avifauna of Flores with the Late Pleistocene non-passerine fossil assemblage from the cave site of Liang Bua to assess whether the Late Pleistocene assemblage differs from the modern avifauna. Randomized permutation tests failed to detect a statistically significant difference in body size distributions, but a significant difference in dietary guild was found, as the modern fauna lacks scavengers. The emerging pattern of avian extinctions on Flores is characterized by a low proportion of extinct species, a loss of large-bodied species, and apparently minor effects on avian community structure. This is in contrast to other oceanic islands, which experienced dramatic changes in avifauna after the arrival of modern humans. Flores' close proximity to other islands and landmasses likely allowed for population connectivity that buffered populations from extinction. Widespread species may also have been able to recolonize if local extirpations took place. The extinction of the large-bodied avian scavengers Leptoptilos robustus and Trigonoceps sp. on Flores is consistent with the pattern of human-caused extinctions on other oceanic islands. However, the loss of these two large scavenging species may be linked to the extinction of the pygmy proboscidean (Stegodon florensis insularis). Such a dependence of avian species on mammalian megafauna, leading to extinction by trophic cascade, is characteristic of continental Late Pleistocene extinctions.

The study employs data from more than 9,000 college calculus students across the United States to build a robust structural equation model. While it is generally thought that students’ beliefs about their own competence in mathematics directly impact their identity as a “math person,” findings indicate that students’ self-perceptions related to competence and performance have an indirect effect on their mathematics identity, primarily by association with students’ interest and external recognition in mathematics. Thus, the model indicates that students’ competence and performance beliefs are not sufficient for their mathematics identity development, and it highlights the roles of interest and recognition.

We used Ecological Niche Modeling (ENM) to evaluate the hypothesis that M. bricenii of the Venezuelan Cordillera de Merida (CM) might have become isolated from populations of its putative sister species, Mazama rufina, in the Colombian Cordillera Oriental (CO). This hypothesis assumes that warm, dry climatic conditions in the Tachira Depression were unsuitable for the species. Our analyses did not reveal morphological differences between specimens geographically attributable to M. bricenii and M. rufina, and phylogenetic analyses of molecular data recovered M. bricenii nested within the diversity of M. rufina. These results indicate that M. bricenii should be regarded as a junior synonym of M. rufina. ENM analyses revealed the existence of suitable climatic conditions for M. rufina in the Tachira Depression during the last glacial maximum and even at present, suggesting that gene flow between populations in the CO and CM may have occurred until at least the beginning of the current interglacial period and may continue today. Because this pattern might characterize other mammals currently considered endemic to the CM, we examined which of these species match two criteria that we propose herein to estimate if they can be regarded as endemic to the CM with confidence: (1) that morphological or molecular evidence exists indicating that the putative endemic taxon is distinctive from congeneric populations in the CO; and (2) that the putative endemic taxon is restricted to either cloud forest or paramo, or both. Only Aepeomys reigi, Cryptotis meridensis, and Nasuella meridensis matched both criteria; hence, additional research is necessary to assess the true taxonomic status and distribution of the remaining species thought to be CM endemics.

We model the surface UV radiation environment for Earth-sized planets orbiting FGKM stars in the circumstellar Habitable Zone for Earth through its geological evolution. We explore four different types of atmospheres corresponding to an early-Earth atmosphere at 3.9 Gyr ago and three atmospheres covering the rise of oxygen to present-day levels at 2.0 Gyr ago, 0.8 Gyr ago, and modern Earth. In addition to calculating the UV flux on the surface of the planet, we model the biologically effective irradiance, using DNA damage as a proxy for biological damage. We find that a pre-biotic Earth (3.9 Gyr ago) orbiting an F0V star receives 6 times the biologically effective radiation as around the early Sun and 3520 times the modern Earth�Sun levels. A pre-biotic Earth orbiting GJ 581 (M3.5 V) receives 300 times less biologically effective radiation, about 2 times modern Earth�Sun levels. The UV fluxes calculated here provide a grid of model UV environments during the evolution of an Earth-like planet orbiting a range of stars. These models can be used as inputs into photo-biological experiments and for pre-biotic chemistry and early life evolution experiments. Copyright (Copyright) 2015. The American Astronomical Society.

An extensive suite of coagulation calculations demonstrates that swarms of 1 cm�10 m planetesimals can form super-Earth mass planets on timescales of 1�3 Gyr. Collisional damping of 10 (super �2) �10 (super 2) cm particles during oligarchic growth is a highlight of these simulations. In some situations, damping initiates a second runaway growth phase where 1000�3000 km protoplanets grow to super-Earth sizes. Our results establish the initial conditions and physical processes required for in situ formation of super-Earth planets at large distances from the host star. For nearby dusty disks in HD 107146, HD 202628, and HD 207129, ongoing super-Earth formation at 80�150 AU could produce gaps and other structures in the debris.

Eavesdropping is typically studied as dyadic predator-prey species interactions; yet in nature, most predators target multiple prey species and most prey must evade multiple predator species. The impact of predator communities on prey signal evolution is not well understood. Predators could converge in their preferences for conspicuous signal properties, generating competition among predators and natural selection on particular prey signal features. Alternatively, predator species could vary in their preferences for prey signal properties, resulting in sensory-based niche partitioning of prey resources. In the Neotropics, many substrate-gleaning bats use the mate-attraction songs of male katydids to locate them as prey. We studied mechanisms of niche partitioning in four substrate-gleaning bat species and found they are similar in morphology, echolocation signal design and prey-handling ability, but each species preferred different acoustic features of male song in 12 sympatric katydid species. This divergence in predator preference probably contributes to the coexistence of many substrate-gleaning bat species in the Neotropics, and the substantial diversity in the mate-attraction signals of katydids. Our results provide insight into how multiple eavesdropping predator species might influence prey signal evolution through sensory-based niche partitioning.

Offspring are highly immature at hatching and depend on oligosaccharide-rich milk for many months. The primary saccharide in long-beaked echidna milk is an acidic trisaccharide Neu4,5Ac sub(2)( alpha 2-3)Gal( beta 1-4)Glc (4-O-acetyl 3'-sialyllactose), but acidic oligosaccharides have not been characterized in platypus milk. In this study, acidic oligosaccharides purified from the carbohydrate fraction of platypus milk were characterized by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and super(1)H-nuclear magnetic resonance spectroscopy. All identified structures, except Neu5Ac( alpha 2-3)Gal( beta 1-4)Glc (3'-sialyllactose) contained Neu4,5Ac sub(2) (4-O-acetyl-sialic acid). These include the trisaccharide 4-O-acetyl 3'-sialyllactose, the pentasaccharide Neu4,5Ac sub(2)( alpha 2-3)Gal( beta 1-4)GlcNAc( beta 1-3)Gal( beta 1-4)Glc (4-O-acetyl-3'-sialyllacto-N-tetraose d) and the hexasaccharide Neu4,5Ac sub(2)( alpha 2-3)Gal( beta 1-4)[Fuc( alpha 1-3)]GlcNAc( beta 1-3)Gal( beta 1-4)Gl c (4-O-acetyl-3'-sialyllacto-N-fucopentaose III). At least seven different octa- to deca-oligosaccharides each contained a lacto-N-neohexaose core (LNnH) and one or two Neu4,5Ac sub(2) and one to three fucose residues. We conclude that platypus milk contains a diverse ( greater than or equal to 20) array of neutral and acidic oligosaccharides based primarily on lactose, lacto-N-neotetraose (LNnT) and LNnH structural cores and shares with echidna milk the unique feature that all identified acidic oligosaccharides (other than 3'-sialyllactose) contain the 4-O-acetyl-sialic acid moiety. We propose that 4-O-acetylation of sialic acid moieties protects acidic milk oligosaccharides secreted onto integumental surfaces from bacterial hydrolysis via steric interference with bacterial sialidases. This may be of evolutionary significance since taxa ancestral to monotremes and other mammals are thought to have secreted milk, or a milk-like fluid containing oligosaccharides, onto skin surfaces.

Combined with results from a field meteorological station, it is found that the gravel components can initially only move under gusty conditions, with the impact of saltating pumice and sand lowering threshold. Pumices can saltate without the impact of sand, implying that they are both an impelling force for other pumices and lithics, and are the most likely clast constituent to undergo transport. Accumulation into bedforms in the tunnel occurs when clasts self organize, with larger, more immobile particles holding others in place, a process that is accentuated in the field on local topographic highs of the undulating ignimbrite bedrock surface. In such an arrangement, pumices and especially lithics remain largely stable, with vibration the dominant mode of motion. This results in sand and silt entrapment and growth of the bedform through infiltration and uplift of the gravel. Resulting bedforms are gravel-mantled ripple-like forms cored with fine grained sediment. The Martian aeolian environment is similar to the Puna in terms of having grains of variable size, infrequent wind gusts, and saltating sand, implying that some TARs on the planet may have formed in a similar way.

Nonetheless, little is known about its body-size variations through time and space. Here, we studied the body-size trends of C. megalodon through its temporal and geographic range to better understand its ecology and evolution. Given that this species was the last of the megatooth lineage, a group of species that shows a purported size increase through time, we hypothesized that C. megalodon also displayed this trend, increasing in size over time and reaching its largest size prior to extinction. We found that C. megalodon body-size distribution was left-skewed (suggesting a long-term selective pressure favoring larger individuals), and presented significant geographic variation (possibly as a result of the heterogeneous ecological constraints of this cosmopolitan species) over geologic time. Finally, we found that stasis was the general mode of size evolution of C. megalodon (i.e., no net changes over time), contrasting with the trends of the megatooth lineage and our hypothesis. Given that C. megalodon is a relatively long-lived species with a widely distributed fossil record, we further used this study system to provide a deep-time perspective to the understanding of the body-size trends of marine apex predators. For instance, our results suggest that (1) a selective pressure in predatory sharks for consuming a broader range of prey may favor larger individuals and produce left-skewed distributions on a geologic time scale; (2) body-size variations in cosmopolitan apex marine predators may depend on their interactions with geographically discrete communities; and (3) the inherent characteristics of shark species can produce stable sizes over geologic time, regardless of the size trends of their lineages.

The impact formed a primary basin, rim materials, and a complex basement structural fabric including faults and valleys that are radial and concentric about the primary basin, as well as structurally-controlled local basins. Since its formation, the basin has been a regional catchment for volatiles and sedimentary materials as well as a dominant influence on the flow of surface ice, debris flows, and groundwater through and over its basement structures. The basin is interpreted to have been occupied by lakes, including a possible Mediterranean-sized sea that formed in the aftermath of the Argyre impact event. The hypothesized lakes froze and diminished through time, though liquid water may have remained beneath the ice cover and sedimentation may have continued for some time. At its deepest, the main Argyre lake may have taken more than a hundred thousand years to freeze to the bottom even absent any heat source besides the Sun, but with impact-induced hydrothermal heat, geothermal heat flow due to long-lived radioactivities in early martian history, and concentration of solutes in sub-ice brine, liquid water may have persisted beneath thick ice for many millions of years. Existence of an ice-covered sea perhaps was long enough for life to originate and evolve with gradually colder and more hypersaline conditions. The Argyre rock materials, diverse in origin and emplacement mechanisms, have been modified by impact, magmatic, eolian, fluvial, lacustrine, glacial, periglacial, alluvial, colluvial, and tectonic processes. Post-impact adjustment of part of the impact-generated basement structural fabric such as concentric faults is apparent. Distinct basin-stratigraphic units are interpreted to be linked to large-scale geologic activity far from the basin, including growth of the Tharsis magmatic-tectonic complex and the growth into southern middle latitudes of south polar ice sheets. Along with the migration of surface and sub-surface volatiles towards the central part of the primary basin, the substantial difference in elevation with respect to the surrounding highlands and Tharsis and the Thaumasia highlands result in the trapping of atmospheric volatiles within the basin in the form of fog and regional or local precipitation, even today. In addition, the impact event caused long-term (millions of years) hydrothermal activity, as well as deep-seated basement structures that have tapped the internal heat of Mars, as conduits, for far greater time, possibly even today. This possibility is raised by the observation of putative open-system pingos and nearby gullies that occur in linear depressions with accompanying systems of faults and fractures. Long-term water and heat energy enrichment, complemented by the interaction of the nutrient-enriched primordial crustal and mantle materials favorable to life excavated to the surface and near-surface environs through the Argyre impact event, has not only resulted in distinct geomorphology, but also makes the Argyre basin a potential site of exceptional astrobiological significance.

This study examines the effects of Paraloid B-72 and Butvar B-98, two common consolidants used in field and museum conservation, on δ13C, δ15N, and δ18O values from bone collagen and hydroxyapatite. The effects of solvent removal (100% acetone, 100% ethanol, 9:1 acetone:xylenes, 9:1 ethanol:xylenes) and drying methods (ambient air, vacuum, oven drying at 80°C) were also examined to determine if bones treated with these consolidants can successfully be cleaned and used for stable isotope analyses. Results show that introduction of Paraloid B-72 or Butvar B-98 in 100% acetone or 100% ethanol, respectively, with subsequent removal by the same solvents and drying at 80°C facilitates the most successful removal of consolidants and solvents. The δ13C values in collagen, δ15N in collagen, δ18O in hydroxyapatite phosphate, and δ13C in hydroxyapatite structural carbonate were unaltered by treatments with Paraloid or Butvar and subsequent solvent removal. The δ18O in hydroxyapatite structural carbonate showed nonsystematic variability when bones were treated with Paraloid and Butvar, which is hypothesized to be a result of hydroxyl exchange when bones are exposed to consolidants in solution. It is therefore recommended that δ18O in hydroxyapatite structural carbonate should not be used in stable isotope studies if bones have been treated with Paraloid or Butvar.

Using MESSENGER orbital high-incidence angle imaging and topographic data, large-scale lobate thrust fault scarps have been mapped globally. The spatial distribution and areal density of the contractional landforms are not uniform; concentrations occur in longitudinal bands and between the north and south hemispheres. Their orientations are generally north-south at low latitude to midlatitude and east-west at high latitudes. The spatial distribution and distribution of orientations of these large-scale contractional features suggest that planet-wide contraction due to interior cooling cannot be the sole source of global stresses. The nonrandom orientations are best explained by a combination of stresses from global contraction and tidal despinning combined with an equator-to-pole variation in lithospheric thickness, while the nonuniform areal density of the contractional features may indicate the influence of mantle downwelling or heterogeneities in lithospheric strength.

They employ compounds from actinomycete bacteria and exocrine glands as antimicrobial agents. Atta colonies have millions of ants and are particularly relevant for understanding hygienic strategies as they have abandoned their ancestors' prime dependence on antibiotic-based biological control in favour of using metapleural gland (MG) chemical secretions. Atta MGs are unique in synthesizing large quantities of phenylacetic acid (PAA), a known but little investigated antimicrobial agent. We show that particularly the smallest workers greatly reduce germination rates of Escovopsis and Metarhizium spores after actively applying PAA to experimental infection targets in garden fragments and transferring the spores to the ants' infrabuccal cavities. In vitro assays further indicated that Escovopsis strains isolated from evolutionarily derived leaf-cutting ants are less sensitive to PAA than strains from phylogenetically more basal fungus-farming ants, consistent with the dynamics of an evolutionary arms race between virulence and control for Escovopsis, but not Metarhizium. Atta ants form larger colonies with more extreme caste differentiation relative to other attines, in societies characterized by an almost complete absence of reproductive conflicts. We hypothesize that these changes are associated with unique evolutionary innovations in chemical pest management that appear robust against selection pressure for resistance by specialized mycopathogens.

A sample (n = 238) of globally distributed, small-scale graben average 26 m wide and 179 m long. When dividing the population into those located within mare and highland regions, we observe that graben located within mare tend to be narrower, shorter, and more irregularly spaced than those in highland terrane. For graben associated with contractional landforms, those in mare are smaller in width and length than those in highlands; the same is true for graben independent of contractional landforms. Assuming a simple geometry, widths of mare graben associated with scarps or ridges are used to estimate the minimum depth range to a mechanical discontinuity (e.g., base of the regolith) resulting in values of approximately 4-48 m. These values are similar to the ranges estimated for regolith thickness from previous workers using Apollo 14 seismic data (3.9-8.5 m), crater counting techniques (8-33 m), crater morphology techniques (2.5-9 m), and crater blockiness (8-31 m). Widths of highland graben yield minimum depths of faulting of 209-296 m. While this range agrees well with models for regolith production (an older surface will have thicker regolith), this estimate likely does not represent the thickness of a mechanical unit due to the fragmented nature of the highland crust (it does not provide a defining boundary between bedrock and regolith). Spacing of mare graben not associated with contractional landforms is used to estimate maximum local mare unit thickness for two graben groups: 190 m for Posidonius and 296 m for Vitello. Maximum graben ages range from late Eratosthenian to early Copernican based on superposed and crosscut crater ages with a group of graben deforming ejecta from Copernicus crater. Data presented here provide further evidence of a globally distributed, young, small-scale graben population that has formed as a result of localized extension either from flexural bending or dilation due to contractional faulting or volcanic uplift, indicating a significant level of recent geologic activity.

However, unlike many convergent margin magmas, it is unlikely that the evolving VFR and EMBB were saturated in a S-bearing volatile phase prior to magnetite fractionation. Hence, the metal-depleting magnetite crisis may be restricted to back-arc basin magmas that do not degas volatiles prior to magnetite fractionation and potentially convergent margin magmas fractionating at high pressures in the continental crust.

However, accumulating field data on juvenile primates suggest variation in the linkages between foraging efficiency, group foraging and social behaviour. In many non-human primates, juvenile ability (strength, coordination and motor skills) does not limit foraging success. If predicted limitations in feeding are not found in juvenile monkeys, it is possible that the gregarious strepsirrhines may show foraging patterns similar to those implicated in the evolution of a life history where long juvenile periods are advantageous. To test these behavioural predictions, I present a mixed longitudinal sample of observations on feeding and foraging behaviour from ring-tailed lemurs (Lemur catta) at the Bez Mahafaly Special Reserve, Madagascar. Like several platyrrhine species, close proximity during foraging, low feeding efficiency and low dietary diversity are not typical of ring-tailed lemurs. The lack of ecological trade-offs in these species may indicate stronger common roles of sociality and social complexity in structuring the elongation of the primate juvenile period. copyright 2015 S.

The dentaries show numerous caenagnathid synapomorphies, including a fused dentary symphysis bearing distinct vascular grooves and associated foramina on its lingual surface, a lingual triturating shelf on the dentary, and extensive pneumatization of the dentary. Cervical and dorsal vertebrae attributed to C. martinsoni show a structure typical for Caenagnathoidea, whereas a referred partial femur is relatively plesiomorphic in having a large, finger-like anterior (lesser) trochanter separated from the greater trochanter. A referred synsacrum has only four vertebrae but may represent an immature individual. Caenagnathasia martinsoni is closely related to the clade comprising the North American Campanian-Maastrichtian caenagnathids. Abstract Copyright (2015) Elsevier, B.V.

Within the bivalve mollusks, this uncertainty is particularly acute for oysters, as the high degree of phenotypic plasticity of their shells creates taxonomic confusion. The integration of molecular data with shell morphology can differentiate species, providing new insights into biogeography, invasions, and ecology of this functionally important group. As an initial step in resolving the identities and current geographic distributions of oyster species, sequence data from the mitochondrial cytochrome oxidase I gene were combined with morphological criteria to confirm the identities of ten oyster species of Ostreidae, Isognomonidae, and Pteriidae, focusing on the Pacific and Caribbean coasts of Panama, since tropical biota have received the least study. The results indicate that Crassostrea virginica, previously only reported from this region along the Yucatan Peninsula and coast of Venezuela, also occurs in the Caribbean waters of Panama. We also document the first record for a species of Saccostrea, a genus native to the Pacific, suggesting an invasion by an unknown non-native Saccostrea species that is now widespread along the Caribbean from the Panama Canal west to Bocas del Toro. Sequences of the internal transcribed spacer region (ITS1) of the ribosomal gene complex (rDNA) did not reveal any hybridization. Considering the high connectivity of shipping and boating in Panama, Saccostrea sp. may have been introduced to the Caribbean by either recreational or commercial vessels, but the timing and potential ecological effects of this invasion remain unknown.

The fossil record provides rich information on past extinctions that can help predict biotic responses. We show that over 23 million years, taxonomic membership and geographic range size consistently explain a large proportion of extinction risk variation in six major taxonomic groups. We assess intrinsic risk-extinction risk predicted by paleontologically calibrated models-for modern genera in these groups. Mapping the geographic distribution of these genera identifies coastal biogeographic provinces where fauna with high intrinsic risk are strongly affected by human activity or climate change. Such regions are disproportionately in the tropics, raising the possibility that these ecosystems may be particularly vulnerable to future extinctions. Intrinsic risk provides a prehuman baseline for considering current threats to marine biodiversity.

Here we examine the impact the Pleistocene had on widely distributed forest vertebrates in a tropical system where the distribution of the habitat was affected by those fluctuations. We conducted a comparative phylogeographical analysis of 28 non-migratory, forest-dependent vertebrates, for which we constructed rooted, intraspecifc phylogenies based on mitochondrial DNA sequences of individuals from at least the three major landmasses in the area (Borneo, Sumatra and the Malay Peninsula) and compared them to hypothetical phylogenies based on independent geological data and climate models regarding connections and relationships between the major landmasses of Sundaland. Java was included where possible. We dated the phylogenies to determine whether patterns of differentiation were concordant across species. In most species, populations on the Malay Peninsula and Sumatra were most closely related, and sister to those from Borneo. The dates of these divergences, however, varied extensively between species. Borneo harbours multiple deeply divergent lineages of many species compared to the diversity within those species. Javan populations of several birds were most divergent relative to those from the rest of the Sunda Shelf. These results suggest a dynamic history, including recurrent population extinctions and replacements and a strong priority effect for local populations. The close relationship between populations in Sumatra and the Malay Peninsula supports the existence of forest on the exposed shelf during the Pleistocene at many different times, and suggests that proximity was more important than the presence of palaeorivers for dispersal of forest taxa between landmasses.

Bulk moduli (B (sub 0) ) calculated using Murnaghan's equation of state are inversely proportional to the size of the tunnel, i.e., 134(4) GPa for hollandite (I2/m), 108(2) GPa for romanechite (C2/m), and 67(5) GPa for todorokite (P2/m). On the other hand, axial compressibilities show different elastic anisotropies depending on the size of the tunnel, i.e., beta (super a) (sub 0) (a/a (sub 0) ) = -0.00066(3) GPa (super -1) , beta (super b) (sub 0) (b/b (sub 0) ) = 0.00179(8) GPa (super -1) , beta (super c) (sub 0) (c/c (sub 0) ) = 0.00637(4) GPa (super -1) [c > b > a] for hollandite; beta (super a) (sub 0) (a/a (sub 0) ) = 0.00485(4) GPa (super -1) , beta (super b) (sub 0) (b/b (sub 0) ) = 0.0016(1) GPa (super -1) , beta (super c) (sub 0) (c/c (sub 0) ) = 0.00199(8) GPa (super -1) [a > c > b] for romanechite; and beta (super a) (sub 0) (a/a (sub 0) ) = 0.00826(9) GPa (super -1) , beta (super b) (sub 0) (b/b (sub 0) ) = 0.0054(1) GPa (super -1) , beta (super c) (sub 0) (c/c (sub 0) ) = 0.00081(8) GPa (super -1) [a > b > c] for todorokite. Overall, the degree of tunnel distortion increases with increasing pressure and correlates with the size of the tunnel, which is evidenced by the gradual increases in the monoclinic beta angles up to 3 GPa of 0.62 degrees , 0.8 degrees , and 1.15 degrees in hollandite, romanechite, and todorokite, respectively. The compression of tunnel manganese oxides is related to the tunnel distortion and the size of the tunnel.

Large storms are defined here as discrete dust events visible in image sequences extending over at least 5 sols (Mars days) and where the dust covers areas beyond the origination region. A total of 65 large dust storms meeting these criteria are identified during the observational period and all are observed during the L (sub s) = 135-30 degrees seasonal window. Dust storms originating in the northern and southern hemispheres appear to form two distinct families. All but two of the storms originating in the northern hemisphere are observed in two seasonal windows at L (sub s) = 180-240 degrees and Ls = 305-350 degrees ; while all but two of those originating in the southern hemisphere are observed during L (sub s) = 135-245 degrees . None of the large dust storms originating in the northern hemisphere are observed to develop to global scale, but some of them develop into large regional storms with peak area >1 X 10 (super 7) km (super 2) and duration on the order of several weeks. In comparison, large dust storms originating in the southern hemisphere are typically much smaller, except notably in the two cases that expanded to global scale (the 2001 and 2007 global storms). Distinct locations of preferred storm origination emerge from the dust storm image sequences, including Acidalia, Utopia, Arcadia and Hellas. A route (trajectory) graph for the observed sequences is provided. The routes are highly asymmetric between the two hemispheres. In the south, for non-global dust storms, the main routes are primarily oriented eastwest, whereas in the north, the routes are primarily north-south and zonally-concentrated into meridional channels. In a few impressive cases, storms originating in the northern hemisphere are observed to "flush" through Acidalia and Utopia, across the equator, and then branch in the low- and mid-southern latitudes. The origin of the 2007 global dust storm is ambiguous from the imaging data. Immediately prior to the global storm, a dust storm sequence from Chryse is identified. This storm's connection to the explosive expansion observed to start from Noachis/West Hellas is unclear due to image coverage. This paper further identifies and describes three different styles of dust storm development, which we refer to as "consecutive dust storms", "sequential activation" and "merging." The evolution of a given dust storm sequence can exhibit different combinations of these growth styles at different stages of development. Dust storm sequences can overlap in time, which makes them good candidate to grow into larger scale.

Now, high-throughput genomics facilitates the detailed exploration of variation in the genome-to-phenotype map among closely related taxa. Here, we investigate the evolution of wing pattern diversity in Heliconius, a clade of neotropical butterflies that have undergone an adaptive radiation for wing-pattern mimicry and are influenced by distinct selection regimes. Using crosses between natural wing-pattern variants, we used genome-wide restriction site-associated DNA (RAD) genotyping, traditional linkage mapping and multivariate image analysis to study the evolution of the architecture of adaptive variation in two closely related species: Heliconius hecale and H. ismenius. We implemented a new morphometric procedure for the analysis of whole-wing pattern variation, which allows visualising spatial heatmaps of genotype-to-phenotype association for each quantitative trait locus separately. We used the H. melpomene reference genome to fine-map variation for each major wing-patterning region uncovered, evaluated the role of candidate genes and compared genetic architectures across the genus. Our results show that, although the loci responding to mimicry selection are highly conserved between species, their effect size and phenotypic action vary throughout the clade. Multilocus architecture is ancestral and maintained across species under directional selection, whereas the single-locus (supergene) inheritance controlling polymorphism in H. numata appears to have evolved only once. Nevertheless, the conservatism in the wing-patterning toolkit found throughout the genus does not appear to constrain phenotypic evolution towards local adaptive optima.

Tapeworms in the genus Taenia exploit a variety of vertebrates, including livestock, humans, and geladas (Theropithecus gelada), monkeys endemic to the alpine grasslands of Ethiopia. Despite Taenia's adverse societal and economic impacts, we know little about the prevalence of disease associated with Taenia infection in wildlife or the impacts of this disease on host health, mortality and reproduction. We monitored geladas at Guassa, Ethiopia over a continuous 61/2 year period for external evidence (cysts or coenuri) of Taenia-associated disease (coenurosis) and evaluated the impact of coenurosis on host survival and reproduction. We also identified (through genetic and histological analyses) the tapeworms causing coenurosis in wild geladas at Guassa as Taenia serialis. Nearly 1/3 of adult geladas at Guassa possessed #>1 coenurus at some point in the study. Coenurosis adversely impacted gelada survival and reproduction at Guassa and this impact spanned two generations: adults with coenuri suffered higher mortality than members of their sex without coenuri and offspring of females with coenuri also suffered higher mortality. Coenurosis also negatively affected adult reproduction, lengthening interbirth intervals and reducing the likelihood that males successfully assumed reproductive control over units of females. Our study provides the first empirical evidence that coenurosis increases mortality and reduces fertility in wild nonhuman primate hosts. Our research highlights the value of longitudinal monitoring of individually recognized animals in natural populations for advancing knowledge of parasite-host evolutionary dynamics and offering clues to the etiology and control of infectious disease.

Both are relatively rare, and as their names suggest, they are closely related to the sperm whale, all being characterized by the presence of a spermaceti organ. However, this organ is much reduced in kogiids and may have become functionally different. Here we describe a fossil kogiid from the late Miocene of Panama and we explore the evolutionary history of the group with special attention to this evolutionary reduction. The fossil consists of cranial material from the late Tortonian ( approximately 7.5 Ma) Pina facies of the Chagres Formation in Panama. Detailed comparison with other fossil and extant kogiids and the results of a phylogenetic analysis place the Panamanian kogiid, herein named Nanokogia isthmia gen. et sp. nov., as a taxon most closely related to Praekogia cedrosensis from the Messinian ( approximately 6 Ma) of Baja California and to Kogia spp. Furthermore our results show that reduction of the spermaceti organ has occurred iteratively in kogiids, once in Thalassocetus antwerpiensis in the early-middle Miocene, and more recently in Kogia spp. Additionally, we estimate the divergence between extant species of Kogia at around the late Pliocene, later than previously predicted by molecular estimates. Finally, comparison of Nanokogia with the coeval Scaphokogia cochlearis from Peru shows that these two species display a greater morphological disparity between them than that observed between the extant members of the group. We hypothesize that this reflects differences in feeding ecologies of the two species, with Nanokogia being more similar to extant Kogia. Nanokogia shows that kogiids have been part of the Neotropical marine mammal communities at least since the late Miocene, and gives us insight into the evolutionary history and origins of one of the rarest groups of living whales.

In amphibians, some symbiotic skin bacteria produce metabolites that inhibit the growth of Batrachochytrium dendrobatidis (Bd), a cutaneous fungal pathogen that has caused many amphibian population declines and extinctions. Treatment with beneficial bacteria (probiotics) prevents Bd infection in some amphibian species and creates optimism for conservation of species that are highly susceptible to chytridiomycosis, the disease caused by Bd. In a laboratory experiment, we used Bd-inhibitory bacteria from Bd-tolerant Panamanian amphibians in a probiotic development trial with Panamanian golden frogs, Atelopus zeteki, a species currently surviving only in captive assurance colonies. Approximately 30% of infected golden frogs survived Bd exposure by either clearing infection or maintaining low Bd loads, but this was not associated with probiotic treatment. Survival was instead related to initial composition of the skin bacterial community and metabolites present on the skin. These results suggest a strong link between the structure of these symbiotic microbial communities and amphibian host health in the face of Bd exposure and also suggest a new approach for developing amphibian probiotics.

Although these groups are widely distributed among reptiles, mammals, amphibians, and birds, the shapes they have evolved are remarkably similar. Kelley and Pyenson review the literature on marine vertebrate groups over time and describe the innovations that facilitated the evolution of these marine forms, the environmental conditions that selected for such convergence of form, and the threats they face from future environment change.Science, this issue 10.1126/science.aaa3716 Many top consumers in today's oceans are marine tetrapods, a collection of lineages independently derived from terrestrial ancestors. The fossil record illuminates their transitions from land to sea, yet these initial invasions account for a small proportion of their evolutionary history. We review the history of marine invasions that drove major changes in anatomy, physiology, and ecology over more than 250 million years. Many innovations evolved convergently in multiple clades, whereas others are unique to individual lineages. The evolutionary arcs of these ecologically important clades are framed against the backdrop of mass extinctions and regime shifts in ocean ecosystems. Past and present human disruptions to marine tetrapods, with cascading impacts on marine ecosystems, underscore the need to link macroecology with evolutionary change.

The sandstone represents a single flood event of a river sourced in the Ancestral Rocky Mountains. Most of the flood-buried plants survived and resumed growth. The stem affinities are uncertain, but they resemble coniferophytic gymnosperms, possibly dicranophylls. Stem diameters (N = 135) vary from 1 to 21 cm, with three strongly overlapping size classes. Modern forest studies predict a monotonically decreasing number (inverse square law) of individuals per size class as diameter increases. This is not seen for fossil stems or = 6 cm diameter obey the predicted inverse square law of diameter distribution. Height estimates calculated from diameter-to-height relationships of modern gymnosperms yielded heights varying from approximately 0.9 m to > 8 m, mean of approximately 3 m. Mean stand density is approximately 2 stems/m (super 2) (20,000 stems/hectare) for all stems > 1 cm diameter. For stems > 7.5 cm or > 10 cm diameter, density is approximately 0.24 stems/m (super 2) (2400 stems/hectare) and 0.14 stems/m (super 2) (1400 stems/hectare). Stem spatial distribution is random (Poisson). Mean all-stem nearest-neighbor distance (NND) averages 36 cm. Mean NND between stems > 7.5 cm and > 10 cm diameter is approximately 1.02 m and 1.36 m. NND increases in approximate isometry with stem diameter, indicating conformation to the same spatial packing rules found in extant forests and other fossil forests of varying ages. Nearest-neighbor distance distribution passes statistical testing for normality, but with positive skew, as often seen in extant NND distributions. The size-frequency distribution of the stems is similar to those of Jurassic, early Tertiary, and extant woodlands; the Early Permian woodland distribution line has the same slope, but differs in that the overall size range increases over time (Cope's rule). The early Permian woodland is self-thinning; its volume versus density relationship shows a self-thinning exponent between -1.25 and -1.5, within the range seen in some extant plant stands (-1.21 to -1.7).

2015-076468 AB - Uranium-lead geochronology in detrital zircons and provenance analyses in eight boreholes and two surface stratigraphic sections in the northern Andes provide insight into the time of closure of the Central American Seaway. The timing of this closure has been correlated with Plio-Pleistocene global oceanographic, atmospheric, and biotic events. We found that a uniquely Panamanian Eocene detrital zircon fingerprint is pronounced in middle Miocene fluvial and shallow marine strata cropping out in the northern Andes but is absent in underlying lower Miocene and Oligocene strata. We contend that this fingerprint demonstrates a fluvial connection, and therefore the absence of an intervening seaway, between the Panama arc and South America in middle Miocene times; the Central American Seaway had vanished by that time.

Turtles in the lower segment of the Castilletes Formation (c. 16.33 Ma) are pleurodires or side-necked turtles belonging to Chelus colombiana Wood, Chelus sp., and Podocnemididae incertae sedis, and cryptodires or hidden-necked turtles attributed to Chelonoidis sp., all of them characterized by the large size of their shells, 1 meter or more total length. The middle segment of the formation (c. 14 Ma) contains specimens of Podocnemididae incertae sedis and Chelonoidis sp. The turtle fauna from Castilletes share taxa with faunas from La Venta (middle-late Miocene of Colombia), Urumaco, and Western Amazonia (late Miocene from Venezuela, Brazil, and Peru); all of these records indicate a wider geographical distribution for podocnemidids, chelids, and testudinids of tropical South America during the early to middle Miocene. The large size of the fossils described here also confirms that gigantism was characteristic of South American tropical turtles during the early Miocene, a trend that lasted at least from the Paleocene to the Pliocene in different lineages.

The lower Chinauta deposit covers 14 km (super 2) and has a thickness of approximately 60 m, whereas the upper Fusagasuga deposit covers 20 km (super 2) and has a thickness of approximately 20 m. The lower Chinauta section consists of matrix-supported gravels, with isolated boulders and massive to moderately bedded structure and local inverse grading. The upper section displays sequences of inversely graded, clast-supported gravels, with boulders >2 m in axial length, capped by massive, matrix-supported fine gravels. The latter are dissected by coarse, channelized gravels. We interpret these facies as a series of debris and hyper-concentrated flows dissected by river channels. The Fusagasuga deposit is dominated by massive to inversely graded matrix-supported gravels with isolated boulders. Single-grain, optically stimulated luminescence dates of the sandy-silty matrix of debris and hyper-concentrated flows constrain the timing of deposition of the Chinauta debris flow deposits between 38.9 and 8.7 ka. We postulate that millennial-scale climate variability is responsible for causing these massive debris flows, through a combination of elevated temperatures and increased rainfall that triggered runoff and sediment transport.

Overwhelmingly, this progress toward building an ever increasingly complete phylogeny of living things has been accomplished through sophisticated analysis of molecular data. In the modern genomic age, molecular genetic data have become very easy and inexpensive to obtain for many species. However, some lineages are poorly represented in or absent from tissue collections, or are unavailable for molecular analysis for other reasons such as restrictive biological sample export laws. Other species went extinct recently and are only available in formalin museum preparations or perhaps even as subfossils. In this brief communication we present a new method for placing cryptic, recently extinct, or hypothesized taxa into an ultrametric phylogeny of extant taxa using continuous character data. This method is based on a relatively simple modification of an established maximum likelihood (ML) method for phylogeny inference from continuous traits. We show that the method works well on simulated trees and data. We then apply it to the case of placing the Culebra Island Giant Anole (Anolis roosevelti) into a phylogeny of Caribbean anoles. Anolis roosevelti is a "crown-giant" ecomorph anole hypothesized to have once been found throughout the Spanish, United States, and British Virgin Islands, but that has not been encountered or collected since the 1930s. Although this species is widely thought to be closely related to the Puerto Rican giant anole, A. cuvieri, our ML method actually places A. roosevelti in a different part of the tree and closely related to a clade of morphologically similar species. We are unable, however, to reject a phylogenetic position for A. roosevelti that places it as sister taxon to A. cuvieri; although close relationship with the remainder of Puerto Rican anole species is strongly rejected by our method.

Processing of both datasets with better image focusing and co-registration techniques, and summing over multiple looks, yields maps with 1-2 km spatial resolution and improved signal to noise ratio, especially in the weaker same-sense circular (SC) polarization. The SC maps are unique to Earth-based observations, and offer a different view of surface properties from orbital mapping using same-sense linear (HH or VV) polarization. Highland or tessera terrains on Venus, which may retain a record of crustal differentiation and processes occurring prior to the loss of water, are of great interest for future spacecraft landings. The Earth-based radar images reveal multiple examples of tessera mantling by impact "parabolas" or "haloes", and can extend mapping of locally thick material from Magellan data by revealing thinner deposits over much larger areas. Of particular interest is an ejecta deposit from Stuart crater that we infer to mantle much of eastern Alpha Regio. Some radar-dark tessera occurrences may indicate sediments that are trapped for longer periods than in the plains. We suggest that such radar information is important for interpretation of orbital infrared data and selection of future tessera landing sites.

Post-plains impact craters of a variety of sizes populate the basin interior, and the spectra of the material they have excavated enable the thickness of the volcanic fill to be estimated and reveal the nature of the subsurface. The thickness of the interior volcanic plains is consistently at least 2.5 km, reaching 3.5 km in places, with thinner fill toward the edge of the basin. No systematic variations in fill thickness are observed with long-wavelength topography or azimuth. The lack of correlation between plains thickness and variations in elevation at large horizontal scales within the basin indicates that plains emplacement must have predated most, if not all, of the changes in long-wavelength topography that affected the basin. There are no embayed or unambiguously buried (ghost) craters with diameters greater than 10 km in the Caloris interior plains. The absence of such ghost craters indicates that one or more of the following scenarios must hold: the plains are sufficiently thick to have buried all evidence of craters that formed between the Caloris impact event and the emplacement of the plains; the plains were emplaced soon after basin formation; or the complex tectonic deformation of the basin interior has disguised wrinkle-ridge rings localized by buried craters. That low-reflectance material (LRM) was exposed by every impact that penetrated through the surface volcanic plains provides a means to explore near-surface stratigraphy. If all occurrences of LRM are derived from a single layer, the subsurface LRM deposit is at least 7.5-8.5 km thick and its top likely once made up the Caloris basin floor. The Caloris-forming impact would have generated a layer of impact melt 3-15 km thick; such a layer could account for the entire thickness of LRM. This material would have been derived from a combination of lower crust and upper mantle.

The thickest (10-40 cm) and oldest parts of the crust (previously reported as up to 640-830 years old), primarily at mid-photic depths of 15-25 m, are composed of buildups of the genus Clathromorphum. Due to its annual growth increments and cycling of Mg content with temperature, Clathromorphum has recently been developed as a high-resolution climate archive. The age of the archive is primarily limited by the boring of mollusks that reduce structural integrity, remove the record, and induce local diagenesis. Depressions and gentle slopes in the deeper portions of Subarctic rocky bottoms often collect mixed bioclastic and siliciclastic sediments, including a dense cover of rhodoliths (Lithothamnion glaciale and Lithothamnion tophiforme). In this paper we describe a transition zone of these two environments that forms on cobble/boulder glacial erratic bottoms in northern Labrador. Clathromorphum compactum buildups on the boulders and cobbles projecting through rhodolith beds can be preserved by fine-grained anaerobic sediments that in turn reduce mollusk boring.

In addition, three dissociated postcranial bones from the same horizon and locality are referable to derived cynodont therapsids. One of these elements, a nearly complete right humerus, can be assigned to Tritylodontidae. Two other bones, an ulna and incomplete ischium, belong to indeterminate derived cynodonts but show no features allowing more precise taxonomic identification. The presence of Oligokyphus in the McCoy Brook Formation provides additional evidence for the remarkably wide geographic distribution of many latest Triassic and Early Jurassic continental tetrapods.

Actual fitness benefits of site familiarity, however, have rarely been demonstrated. We placed GPS collars on 57 female black-tailed deer in coastal California over 4 years to track seasonal movements, determine home ranges, and monitor survival and cause of mortality. We used seasonal home ranges and core areas as measures of site familiarity and modeled how mortality risk varied with use of familiar areas, forage availability, age class, and elevational overlap with simultaneously collared pumas using Cox proportional hazards models. The use of familiar areas was the best predictor of mortality risk, and deer that had a 40 % probability of leaving their home range in a given week were four times more likely to die. Puma predation was the largest cause of mortality, and deer whose average weekly elevation was farther from the average elevation of pumas were less likely to die. While forage availability was not related to mortality risk, deer with lower forage availability were more likely to leave their home range during both summer and winter. Our results provide a rare example of fitness benefits associated with site familiarity and the use of familiar areas as a refuge from predation. The benefits of site familiarity are likely widespread in ungulates, especially when there are stable home ranges, complex habitats, and few cues of predation risk.

The first was from February to September 1890; the second from January to July 1895 when Abbott rushed back to Madagascar not only to collect for the Smithsonian but also to join the Merina in their unsuccessful war of independence against the encroaching French government. Beyond summarizing localities he visited and the current organization and usefulness of his collections for research, the article attempts to interpret archival records to assess Abbott's collecting focus, biases, and purposes; his perspectives on contemporaneous events in Madagascar; and also the role that 'naturalist' collectors such as Abbott played within the history of anthropology and of museums. Ethnographic information is embedded not only within the ethnographic collections but also within associated biological collections and archives.

We analyzed the severity of climate change predicted for existing dead zones, and found that 94% of dead zones are in regions that will experience at least a 2 degree C temperature increase by the end of the century. We then reviewed how climate change will exacerbate hypoxic conditions through oceanographic, ecological, and physiological processes. We found evidence that suggests numerous climate variables including temperature, ocean acidification, sea-level rise, precipitation, wind, and storm patterns will affect dead zones, and that each of those factors has the potential to act through multiple pathways on both oxygen availability and ecological responses to hypoxia. Given the variety and strength of the mechanisms by which climate change exacerbates hypoxia, and the rates at which climate is changing, we posit that climate change variables are contributing to the dead zone epidemic by acting synergistically with one another and with recognized anthropogenic triggers of hypoxia including eutrophication. This suggests that a multidisciplinary, integrated approach that considers the full range of climate variables is needed to track and potentially reverse the spread of dead zones.

Yet, the role of phenotypic plasticity - an organism's ability to change its phenotype in response to the environment - and environmental influences in the dramatic phenotypic transformations that occurred during plant domestication are poorly understood. Another factor possibly influential in agricultural origins, the productivity of crop plant wild progenitors in Late Pleistocene vs. Holocene environments, has received increasing attention recently and merits further investigation. In this study, we examined phenotypic characteristics and productivity (biomass, seed yield) in the wild progenitor of maize, the teosinte Zea mays ssp. parviglumis H.H. Iltis & Doebley, when it was first exploited and cultivated by growing it in atmospheric CO (sub 2) concentrations and temperatures characteristic of the late-glacial and early Holocene periods. Plants responded with a number of attributes uncharacteristic of teosinte in today's environments, including maize-type traits in vegetative architecture, inflorescence sexuality, and seed maturation. Teosinte productivity was significantly lower in late-glacial compared with early Holocene and modern environments. Our evidence indicates that: a) ancestral biological characteristics of crop plant progenitors aren't always predicted from living examples, b) some important maize phenotypic traits were present at initial human exploitation and selection, and c) Pleistocene plant productivity should be considered a significant factor in the chronology of food production origins.

Squamates include (super 9000 species, making them the second largest group of terrestrial vertebrates. They are important medicinally and as model systems for ecological and evolutionary research. However, studies of squamate biology are hindered by uncertainty over their relationships, and some consider squamate phylogeny unresolved, given recent conflicts between molecular and morphological results. To resolve these conflicts, we expand existing morphological and molecular datasets for squamates (691 morphological characters and 46 genes, for 161 living and 49 fossil taxa, including a new set of 81 morphological characters and adding two genes from published studies) and perform integrated analyses. Our results resolve higher-level relationships as indicated by molecular analyses, and reveal hidden morphological support for the molecular hypothesis (but not vice-versa). Furthermore, we find that integrating molecular, morphological, and paleontological data leads to surprising placements for two major fossil clades (Mosasauria and Polyglyphanodontia). These results further demonstrate the importance of combining fossil and molecular information, and the potential problems of estimating the placement of fossil taxa from morphological data alone. Thus, our results caution against estimating fossil relationships without considering relevant molecular data, and against placing fossils into molecular trees (e.g. for dating analyses) without considering the possible impact of molecular data on their placement.

However, there is a paucity of such studies that focus on Neotropical insect groups. Synoeca de Saussure, 1852 is a Neotropical swarm-founding social wasp genus with five described species that is broadly and conspicuously distributed throughout the Neotropics. Here, we infer the phylogenetic relationships, diversification times, and historical biogeography of Synoeca species. We also investigate samples of the disjoint populations of S. septentrionalis that occur in both northwestern parts of South America through Central American and the Brazilian Atlantic rainforests. Our results showed that the interspecific relationships for Synoeca could be described as follows: (S. chalibea + S. virginea) + (S. cyanea + (S. septentrionalis/S. surinama)). Notably, samples of S. septentrionalis and S. surinama collected in the Atlantic Forest were interrelated and may be the result of incomplete lineage sorting and/or mitochondrial introgression among them. Our Bayesian divergence dating analysis revealed recent Plio-Pleistocene diversification in Synoeca. Moreover, our biogeographical analysis suggested an Amazonian origin of Synoeca, with three main dispersal events subsequently occurring during the Plio-Pleistocene.

Unlike traditional, breeding-season-focused models of migratory populations, FAC population models include the effects on population dynamics of events in both the breeding and the nonbreeding season (i.e. winter and migration). Given that migratory birds can spend most of the year away from the breeding grounds and face seasonally specific threats and limitation, FAC models can provide critical and unique insights about their population dynamics. We review existing FAC population model types, including demographic network models, seasonal matrix models, and individual-based models, with examples of each type. We also suggest some approaches new to FAC population modeling-integrated population models and integral projection models-and make recommendations for the development and implementation of these models. Incorporating model components such as density dependence, migratory connectivity (the demographic linkages between breeding and nonbreeding areas), and seasonal interactions can be critical for model realism but can also increase model complexity and development time. Much of the development of FAC population models has been more theoretical than applied. The main limitation to the application of the developed models is availability of empirical data for all annual stages, particularly knowledge of migratory connectivity and density-dependent seasonal survival. As these data become more available, the models outlined here should find additional uses.

The meteorite's major characteristics are a high metal content with a solar Co/Ni ratio, a majority of chemically-zoned metal grains, cryptocrystalline chondrules, grossite- and hibonite-bearing refractory inclusions, the presence of SiO (sub 2) objects and the lack of a fine-grained matrix. The bulk chemical and isotope composition of oxygen in the meteorite is typical for CH chondrites. However, among all CH chondrites, NWA 470 is the most enriched in iron. Notable among the chondrite's components are refractory inclusions and chondrules of several different generations, which may have formed under either canonical nebular or dust-rich conditions. In general, the origin of refractory inclusions, SiO (sub 2) objects and zoned metal can be explained through fractional condensation with partial isolation of the condensates. Dark inclusions were probably included in the material of CH chondrites from a different parent body, similar in composition to CM chondrites. After mixing of these multiple types of material during accretion, the components of NWA 470 were not further affected by aqueous alteration or thermal metamorphic processes, and the components' primary characteristics have been preserved.

The deep-water cycle can be modeled through parameterized convection models coupled with a volatile recycling model. The convection of the silicate mantle is linked to the volatile cycle through the water-dependent viscosity. Important differences in surface water content are found for different parameterizations of convection. Surface oceans are smaller and more persistent for single layer convection, rather than convection by boundary layer instability. Smaller planets have initially larger oceans but also return that water to the mantle more rapidly than larger planets. Super-Earths may therefore be less habitable in their early years than smaller planets, but their habitability (assuming stable surface conditions) will persist much longer.

This interval marks the extinction of the enigmatic Ediacara biota (a collection of multicellular eukaryotes whose affinities with modern metazoans are unknown), the Cambrian 'explosion' of modern animal groups, and a shift from stratified, microbially-dominated 'matgrounds', to more recognizable Phanerozoic 'mixgrounds' colonized by a wide variety of infaunal metazoans. Key to understanding this transition is unraveling the causes behind the extinction of the Ediacara biota, as these made way for the proliferation of modern animal groups. Here, we present new data from latest Ediacaran sections in southern Namibia that preserve both Ediacaran soft-body fossils, and trace fossils that represent the activity of Cambrian-type animals. We show that: 1) latest Ediacaran communities had low evenness and species richness, consistent with interpretation as 'stressed' ecosystems; and, 2) these Ediacaran communities co-existed with cnidarian grade trace-makers that may represent some of the earliest evidence for passive predation. Together, these findings provide support for a 'biotic replacement' model of the extinction of the Ediacara biota, in which extinction was protracted, and ultimately caused by the evolution of Cambrian-style predators and 'ecosystem engineers'. These findings also suggest that the first mass extinction of complex life was biologically mediated, in stark contrast to the subsequent Phanerozoic 'Big Five' events.

We evaluated the migratory connectivity of a Neotropical migratory songbird, the Ovenbird (Seiurus aurocapilla) using archival light-level geolocators deployed at two breeding and four nonbreeding locations while incorporating Ovenbird abundance as prior information using Bayes' Rule. We also included band recoveries submitted to the United States Geological Survey's Bird Banding Laboratory to assess connectivity of areas where geolocators were not deployed. Ovenbirds exhibited strong migratory connectivity between breeding and nonbreeding season, which has important implications for various aspects of the ecology, evolution, and conservation.

These reductions often lead to profound shifts in the ecology of entire communities and ecosystems. However, the effects of these large-wildlife declines on other taxa likely hinge upon both underlying abiotic properties of these systems and on the types of secondary anthropogenic changes associated with wildlife loss, making impacts difficult to predict. Collectively, the results (1) highlight the importance of context in determining the impacts of large-wildlife decline on small-mammal communities, (2) emphasize the challenges in extrapolating results from controlled experimental studies to predict the effects of wildlife declines that are accompanied by secondary land-uses, and (3) suggest that, because of the context-dependent nature of the responses to large-wildlife decline, large-wildlife status alone cannot be reliably used to predict small-mammal community changes.

We evaluated factors influencing the invasion of nonnative Phragmites australis, which has been rapidly expanding in brackish tidal wetlands in Chesapeake Bay. We conducted a survey of naturally occurring small-scale disturbances (removal of vegetation and/or sediment deposition) across four plant communities; determined the effects of small-scale disturbance and biotic resistance on P. australis seedling and rhizome emergence; and tested the effects of size and frequency of small-scale disturbances on seedling emergence and survival of transplanted seedlings. The results of our study demonstrate that the invasion window for seeds is in disturbed areas in high-marsh plant communities that flood less frequently; seedling emergence in undisturbed areas was negligible. Establishment of shoots from rhizome segments was low in all plant communities. Disturbance size and frequency had no significant impact on seed germination and seedling survival. Our findings provide evidence that small-scale within-wetland disturbances are important for the invasion of the nonnative lineage of P. australis by seeds in brackish tidal wetlands in Chesapeake Bay. Efforts to reduce disturbances, large and small, in wetlands can be used to limit P. australis invasion by seed, but invasion by rhizome is still likely to occur across many plant communities irrespective of the presence of disturbance.

In situ mapping of the petrographic, elemental, structural, and stratigraphic characteristics of outcrops and rocks distinguishes four mappable bedrock lithologic units. Three of these rock units predate the surrounding Burns formation sulfate-rich sandstones and one, the Matijevic Formation, represents conditions on early Mars predating the formation of Endeavour Crater. The stratigraphy assembled from these observations includes several geologic unconformities. The differences in lithologic units across these unconformities record changes in the character and intensity of the Martian aqueous environment over geologic time. Water circulated through fractures in the oldest rocks over periods long enough that texturally and elementally significant alteration occurred in fracture walls. These oldest pre-Endeavour rocks and their network of mineralized and altered fractures were preserved by burial beneath impact ejecta and were subsequently exhumed and exposed. The alteration along joints in the oldest rocks and the mineralized veins and concentrations of trace metals in overlying lithologic units is direct evidence that copious volumes of mineralized and/or hydrothermal fluids circulated through the early Martian crust. The wide range in intensity of structural and chemical modification from outcrop to outcrop along the crater rim shows that the ejecta of large (>8 km in diameter) impact craters is complex. These results imply that geologic complexity is to be anticipated in other areas of Mars where cratering has been a fundamental process in the local and regional geology and mineralogy.

Our material comprises calcified cordaitaleans and tree-fern axes, preserved in braided channel deposits, and interpreted as remains of subhumid riparian vegetation distinct from that of coeval coal swamps. The first plant-arthropod association, attributed to herbivorous insects, comprises cambial damage to cordaitalean leafy branches, resulting in traumatic wound response. The second and most widespread association, attributable to detritivorous oribatid mites, includes tunnels and galleries containing widely scattered, clustered, or densely packed microcoprolites within the inner root mantle of marattialean tree ferns and cordaitalean trunks and branches. Diameter data for tunnels and microcoprolites are multimodal, recording four or five instars of oribatid mites that parallel instar-based fecal pellet and body lengths in modern taxa. The third association attributed, possibly, to an arthropleurid, comprises a single, very large (19 X 14 mm) coprolite. Included plant fragments support a previous conjecture that arborescent lycopsids formed part of this iconic arthropod's diet. Mucus-lined burrows within the macrocoprolite imply that fecal material was processed by annelids. The high diversity and frequency of plant-arthropod associations are unusual for Mid-Pennsylvanian time, and may reflect previously undetected interactions in those ecosystems that lay outside "coal forest swamps.

Although global forces are at play, the effects of sea-level rise are highly localized due to variability in glacial isostatic adjustment (GIA) effects. Interpretations of coastal paleoecology and archeology require reliable estimates of ancient shorelines that account for GIA effects. Here we build on previous models for California's Northern Channel Islands, producing more accurate late Pleistocene and Holocene paleogeographic reconstructions adjusted for regional GIA variability. This region has contributed significantly to our understanding of early New World coastal foragers. Sea level that was about 80-85 m lower than present at the time of the first known human occupation brought about a landscape and ecology substantially different than today. During the late Pleistocene, large tracts of coastal lowlands were exposed, while a colder, wetter climate and fluctuating marine conditions interacted with rapidly evolving littoral environments. At the close of the Pleistocene and start of the Holocene, people in coastal California faced shrinking land, intertidal, and subtidal zones, with important implications for resource availability and distribution.

Yet, public health and animal disease surveillance programs continue to operate independently. Here, we assessed whether recent emerging zoonotic pathogens (n = 143) are known to cause morbidity or mortality in their animal host and if so, whether they were first detected with an animal morbidity/mortality event. We show that although sick or dead animals are often associated with these pathogens (52%), only 9% were first detected from an animal morbidity or mortality event prior to or concurrent with signs of illness in humans. We propose that an animal morbidity and mortality reporting program will improve detection and should be an essential component of early warning systems for zoonotic diseases. With the use of widespread low-cost technology, such a program could engage both the public and professionals and be easily tested and further incorporated as part of surveillance efforts by public health officials.

Using life history and demographic data derived from regional studbooks, this study examined life expectancy and longevity in a total of 782 wild-caught (WC) and captive-bred (CB) varanid lizards of seven species maintained in North American zoos since 1926. The average lifespans for WC and CB animals were 6.3 plus or minus 0.3 and 9.3 plus or minus 0.4 years, respectively, with CB males living significantly longer than females (P=0.009). A total of 26.4% of WC and 22.5% of CB animals experienced mortality during their first 2 years in captivity, with mortality during this period greatest among Varanus rudicollis and V. prasinus. A positive correlation was observed between life expectancy and adult body mass in captive-bred individuals (r=0.981; P=0.002). Wild-caught females with a history of successful reproduction had a significantly greater average lifespan than non-reproducing females (P<0.0001). Results from this study suggest that varanids have not been reaching their lifespan capacities in North American zoos. In light of these findings, several husbandry-related factors which may be affecting the welfare and lifespans of varanids in zoos are identified and discussed. This study also highlights the utility of demographic and life history data in captive animal management, and offers a general framework for future herpetological studies of a similar nature.

The majority of this pool is assumed to be relatively stable and to turn over slowly over decades to centuries, although changes in nutrient status can influence soil organic matter on shorter timescales. We measured carbon, nitrogen, and phosphorus concentrations in soil organic matter and leaf litter over an annual cycle in a long-term nutrient addition experiment in lowland tropical rain forest in the Republic of Panama. Total soil carbon was not affected by a decade of factorial combinations of nitrogen, phosphorus, or potassium. Nitrogen addition increased leaf litter nitrogen concentration by 7 % but did not affect total soil nitrogen. Phosphorus addition doubled the leaf litter phosphorus concentration and increased soil organic phosphorus by 50 %. Surprisingly, concentrations of carbon, nitrogen, and phosphorus in soil organic matter declined markedly during the four-month dry season, and then recovered rapidly during the following wet season. Between the end of the wet season and the late dry season, total soil carbon declined by 16 %, total nitrogen by 9 %, and organic phosphorus by between 19 % in control plots and 25 % in phosphorus addition plots. The decline in carbon and nitrogen was too great to be explained by changes in litter fall, bulk density, or the soil microbial biomass. However, a major proportion of the dry-season decline in soil organic phosphorus was explained by a corresponding decline in the soil microbial biomass. These results have important implications for our understanding of the stability and turnover of organic matter in tropical forest soils, because they demonstrate that a considerable fraction of the soil organic matter is seasonally transient, despite the overall pool being relatively insensitive to long-term changes in nutrient status.

However, long-term chronosequences occurring under seasonally dry climates remain scarce. We assessed soil development and nutrient dynamics along the Jurien Bay chronosequence, a 2 million-year sequence of coastal dunes in southwestern Australia. The chronosequence is significant because it occurs in a Mediterranean climate and supports hyperdiverse shrublands within a global biodiversity hotspot. Young soils formed during the Holocene (2,000,000 years old) are completely leached of iron oxides and consist of bleached quartz sand several meters deep. Changes in soil organic matter and nutrient status along the Jurien Bay chronosequence are consistent with patterns observed along other long-term chronosequences and correspond closely to expectations of the Walker and Syers (1976) model of biogeochemical change during pedogenesis. Organic carbon and nitrogen (N) accumulate rapidly to maximum amounts in intermediate-aged Holocene dunes and then decline as soils age. In contrast, total phosphorus (P) declines continuously along the chronosequence to extremely low levels after 2 million years of pedogenesis, eventually representing some of the lowest P soils globally. Ratios of soil organic carbon to P and N to P increase continuously along the chronosequence, consistent with a shift from N limitation on young soils to extreme P limitation on old soils. Phosphorus fractionation by sequential extraction reveals a rapid decline in primary and non-occluded phosphate and an increase in organic and occluded P as soils age. Concentrations of extractable (that is, readily bioavailable) N and P, as well as exchangeable cations, are greatest in Holocene dunes and decline to low levels in Pleistocene dunes. Extractable micronutrient concentrations were generally very low and varied little across the chronosequence. We conclude that the Jurien Bay chronosequence is an important example of changing patterns of nutrient limitation linked to long-term soil and ecosystem development under a Mediterranean climate.

Simulations of the atmospheric effects of a variety of events (such as supernovae, gamma-ray bursts, and solar proton events) have been previously published, along with estimates of biological damage at Earth's surface. In this work, we employed the Tropospheric Ultraviolet and Visible (TUV) radiative transfer model to expand and improve calculations of surface-level irradiance and biological impacts following an ionizing radiation event. We considered changes in surface-level UVB, UVA, and photosynthetically active radiation (visible light) for clear-sky conditions and fixed aerosol parameter values. We also considered a wide range of biological effects on organisms ranging from humans to phytoplankton. We found that past work overestimated UVB irradiance but that relative estimates for increase in exposure to DNA-damaging radiation are still similar to our improved calculations. We also found that the intensity of biologically damaging radiation varies widely with organism and specific impact considered; these results have implications for biosphere-level damage following astrophysical ionizing radiation events. When considering changes in surface-level visible light irradiance, we found that, contrary to previous assumptions, a decrease in irradiance is only present for a short time in very limited geographical areas; instead we found a net increase for most of the modeled time-space region. This result has implications for proposed climate changes associated with ionizing radiation events.

AN - 1660029932; 25595765 AB - Water discharging from abandoned coal mines can contain extremely high manganese levels. Removing this metal is an ongoing challenge. Passive Mn(II) removal beds (MRBs) contain microorganisms that oxidize soluble Mn(II) to insoluble Mn(III/IV) minerals, but system performance is unpredictable. Using amplicon pyrosequencing, we profiled the bacterial, fungal, algal, and archaeal communities in four MRBs, performing at different levels, in Pennsylvania to determine whether they differed among MRBs and from surrounding soil and to establish the relative abundance of known Mn(II) oxidizers. Archaea were not detected; PCRs with archaeal primers returned only nontarget bacterial sequences. Fungal taxonomic profiles differed starkly between sites that remove the majority of influent Mn and those that do not, with the former being dominated by Ascomycota (mostly Dothideomycetes) and the latter by Basidiomycota (almost entirely Agaricomycetes). Taxonomic profiles for the other groups did not differ significantly between MRBs, but operational taxonomic unit-based analyses showed significant clustering by MRB with all three groups (P < 0.05). Soil samples clustered separately from MRBs in all groups except fungi, whose soil samples clustered loosely with their respective MRB. Known Mn(II) oxidizers accounted for a minor proportion of bacterial sequences (up to 0.20%) but a greater proportion of fungal sequences (up to 14.78%). MRB communities are more diverse than previously thought, and more organisms may be capable of Mn(II) oxidation than are currently known. Copyright © 2015, American Society for Microbiology.

For ants, the task specialization hypothesis (TSH) proposes that increased behavioural specialization enabled by larger group size corresponds to anatomical specialization of worker brains. Alternatively, the social brain hypothesis proposes that increased levels of social stimuli in larger colonies lead to enlarged brain regions in all workers, regardless of their task specialization. We tested these hypotheses in acacia ants (Pseudomyrmex spinicola), which exhibit behavioural but not morphological task specialization. In wild colonies, we marked, followed and tested ant workers involved in foraging tasks on the leaves (leaf-ants) and in defensive tasks on the host tree trunk (trunk-ants). Task specialization increased with colony size, especially in defensive tasks. The relationship between colony size and brain region volume was task-dependent, supporting the TSH. Specifically, as colony size increased, the relative size of regions within the mushroom bodies of the brain decreased in trunk-ants but increased in leaf-ants; those regions play important roles in learning and memory. Our findings suggest that workers specialized in defence may have reduced learning abilities relative to leaf-ants; these inferences remain to be tested. In societies with monomorphic workers, brain polymorphism enhanced by group size could be a mechanism by which division of labour is achieved.

We explore how the minimum required core mass, M (sub crit) , depends on a non-ideal equation of state (EOS) and on opacity changes due to grain growth across a range of stellocentric distances from 5-100 AU. This minimum M (sub crit) applies when planetesimal accretion does not substantially heat the atmosphere. Compared to an ideal gas polytrope, the inclusion of molecular hydrogen (H (sub 2) ) dissociation and variable occupation of H (sub 2) rotational states increases M (sub crit) . Specifically, M (sub crit) increases by a factor of approximately 2 if the H (sub 2) spin isomers, ortho- and parahydrogen, are in thermal equilibrium, and by a factor of approximately 2-4 if the ortho-to-para ratio is fixed at 3:1. Lower opacities due to grain growth reduce M (sub crit) . For a standard disk model around a Solar mass star, we calculate M (sub crit) approximately 8 M (sub ⊕) at 5 AU, decreasing to approximately 5 M (sub ⊕) at 100 AU, for a realistic EOS with an equilibrium ortho-to-para ratio and for grain growth to centimeter-sizes. If grain coagulation is taken into account, M (sub crit) may further reduce by up to one order of magnitude. These results for the minimum critical core mass are useful for the interpretation of surveys that find exoplanets at a range of orbital distances. Copyright (Copyright) 2015.

Based on 86 radial velocity observations obtained with the HARPS-N spectrograph on the Telescopio Nazionale Galileo and 32 archival Keck/HIRES observations, we present a precise mass estimate of 4.02 + or - 0.68 M (sub ⊕) . The corresponding high density of 6.88 + or - 1.18 g cm (super -3) is consistent with a rocky composition of primarily iron and magnesium silicate. We compare Kepler-93b to other dense planets with well-constrained parameters and find that between 1 and 6 M (sub ⊕) , all dense planets including the Earth and Venus are well-described by the same fixed ratio of iron to magnesium silicate. There are as of yet no examples of such planets with masses >6 M (sub ⊕) . All known planets in this mass regime have lower densities requiring significant fractions of volatiles or H/He gas. We also constrain the mass and period of the outer companion in the Kepler-93 system from the long-term radial velocity trend and archival adaptive optics images. As the sample of dense planets with well-constrained masses and radii continues to grow, we will be able to test whether the fixed compositional model found for the seven dense planets considered in this paper extends to the full population of 1-6 M (sub ⊕) planets.

Here a new composite record of the sea surface temperature, SST, variation in the northern South China Sea (SCS) during the late Holocene is constructed by combining seven seasonally-resolved coral and Tridacna gigas Sr/Ca-based SST time-windows with the instrumental SST record from modern interval between 1990 and 2000. This composite multi-proxy marine record, together with the reconstructions from mainland China and tropical Western Pacific, indicates that the late Holocene warm periods, the Roman Warm Period (RWP) and Medieval Warm Period (MWP), were prominently imprinted and documented in the climatic and environmental history of the East Asia-Western Pacific region. Meanwhile, substantial and significant SST seasonality variations during the late Holocene were observed in the composite record. The observed increase in seasonality (or amplitude of seasonal cycles) during the cold periods around our study area was probably caused by the different amplitudes between winter versus summer SST variations in northern SCS, with much larger SST variation during winters than during summers for the late Holocene. In addition, the distinctive warm, cold and neutral climatic episodes identified in our northern SCS composite SST record correspond well with other paleo reconstructions from mainland China and especially well with the Northern Hemisphere-wide composites by Moberg et al.

Molecular data support the conclusion of prior morphometric studies that all living Cerion inhabiting Aruba, Curacao and Bonaire are members of a single species, C. uva. Sequence variability among and within populations is not sufficiently discontinuous to segregate populations into discrete, species-level taxa. Three of four subspecies, proposed on the basis of geographic isolation during the Quaternary, C. uva uva (Linnaeus, 1758), the nominotypical subspecies from eastern Curacao, C. uva knipensis Baker, 1924, from western Curacao, and C. uva bonairensis Baker, 1924, from Bonaire, are all supported by distinctive haplotypes. Cerion uva arubanum Baker, 1924, a taxon based on living specimens from Aruba, is shown to be a synonym of C. uva uva, with which it shares a preponderance of haplotypes. It is conjectured that C. uva was widespread on Aruba during the Quaternary, but had become extinct on that island, and was reintroduced from a population near Willemstad in eastern Curacao by humans (either by Caquetio Indians or by European settlers) within the past 800 years. Further investigation is needed to determine if Quaternary Aruban Cerion warrant subspecific recognition. On the island of Curacao, molecular data lend support to the partition of the Cerion fauna into C. uva knipensis, which is confined to an isolated western region, as defined by Baker, and C. uva uva, which inhabits a broad, eastern region that is composed of Baker's central and eastern regions. A population at Ronde Klip in eastern Curacao has remained genetically isolated, and retains subspecific status as C. uva diablensis Baker, 1924. A neotype is designated for Turbo uva Linnaeus, 1758, as is necessary to provide an objective standard of reference for this species-group taxon, and for the genus- and family-level taxa based upon it.

A new classification of the cone snails AN - 1773796922; 2016-024810 AB - We present a new classification for the genus Conus sensu lato (family Conidae), based on molecular phylogenetic analyses of 329 species. This classification departs from both the traditional classification in only one genus and from a recently proposed shell- and radula-based classification scheme that separates members of this group into five families and 115 genera. Roughly 140 genus-group names are available for Recent cone snails. We propose to place all cone snails within a single family (Conidae) containing four genera-Conus, Conasprella, Profundiconus and Californiconus (with Conus alone encompassing about 85% of known species)-based on the clear separation of cone snails into four distinct and well-supported groups/lineages in molecular phylogenetic analyses. Within Conus and Conasprella, we recognize 57 and 11 subgenera, respectively, that represent well-supported subgroupings within these genera, which we interpret as evidence of intrageneric distinctiveness. We allocate the 803 Recent species of Conidae listed as valid in the World Register of Marine Species into these four genera and 71 subgenera, with an estimate of the confidence for placement of species in these taxonomic categories based on whether molecular or radula and/or shell data were used in these determinations. Our proposed classification effectively departs from previous schemes by (1) limiting the number of accepted genera, (2) retaining the majority of species within the genus Conus and (3) assigning members of these genera to species groups/subgenera to enable the effective communication of these groups, all of which we hope will encourage acceptance of this scheme.

We used rank abundance distribution plots (RADs), Renyi entropy plots, common theoretical community models, ordination analysis of similarities (ANOSIM and Clusters), and abundance spectra analyses to study the effects of a gradual natural population decline and an anthropogenic punctuated disturbance on the structure of octocoral communities in Panama, considered a hot spot area for octocoral diversity in the Tropical Eastern Pacific. Over a 17-month period, no significant change was found in community structure after a natural yearly population decline of 25.2%. After a disturbance, however, different recovery trajectories were observed in various coral communities. Possible physical and biological explanations for the observed differences include initial local species diversity and abundance, species life history patterns, colony morphology, and the geographical location of the community. Differences in community structure between study sites were best described using a combination of community descriptors, RADs, and abundance spectra. Renyi plots were useful in identifying changes in community structure, whereas the extent of the changes was best evaluated using ANOSIM and cluster analysis.

It has been notoriously difficult to extract information about energetic particle spectra in the corona, owing to a lack of in situ measurements. It is possible, however, to combine remote observations with data-driven models in order to deduce coronal shock properties relevant to the local acceleration of SEPs and their heliospheric connectivity to near-Earth space. We present such novel analysis applied to the 2011 May 11 CME event on the western solar limb, focusing on the evolution of the eruption-driven, dome-like shock wave observed by the Atmospheric Imaging Assembly (AIA) EUV telescopes on board the Solar Dynamics Observatory spacecraft. We analyze the shock evolution and estimate its strength using emission measure modeling. We apply a new method combining a geometric model of the shock front with a potential field source surface model to estimate time-dependent field-to-shock angles and heliospheric connectivity during shock passage in the low corona. We find that the shock was weak, with an initial speed of ~450 km s super(-1). It was initially mostly quasi-parallel, but a significant portion of it turned quasi-perpendicular later in the event. There was good magnetic connectivity to near-Earth space toward the end of the event as observed by the AIA instrument. The methods used in this analysis hold a significant potential for early characterization of coronal shock waves and forecasting of SEP spectra based on remote observations.

We present a new model to estimate leaf area density profiles from discrete multireturn data derived by airborne waveform light detection and ranging (lidar), a model based on stochastic radiative transfer theory. We tested the method on simulated ray tracing data for highly clumped forest canopies, both vertically homogenous and vertically inhomogeneous. Our method was able to reproduce simulated vertical foliage profiles with small errors and predictable biases in dense canopies (leaf area index=6) including layers below densely foliated upper canopies. As a case study, we then applied the method to real multireturn airborne lidar data for a 50ha plot of moist tropical forest on Barro Colorado Island, Panama. The method is suitable for estimating foliage profiles in a complex tropical forest, which opens new avenues for analyses of spatial and temporal variations in foliage distributions.

The comparative analysis of the country's three social and agro-ecological regions shows that the shortest fallows are not associated with the longest cultivation periods and with higher population densities. Further, the fast-track conversion of shifting cultivation into permanent agriculture with orchards is similar in the three regions, and is not occurring in response to land scarcity, shorter fallows and decreasing soil fertility. The article, then, adds depth to the understanding of the complexity of shifting cultivation in Africa and of its multiple routes of transformation into permanent agriculture.

This review describes an international network of 59 long-term forest dynamics research sites (CTFS-ForestGEO) useful for characterizing forest responses to global change. Within very large plots (median size 25 ha), all stems greater than or equal to 1 cm diameter are identified to species, mapped, and regularly recensused according to standardized protocols. CTFS-ForestGEO spans 25 degree S-61 degree N latitude, is generally representative of the range of bioclimatic, edaphic, and topographic conditions experienced by forests worldwide, and is the only forest monitoring network that applies a standardized protocol to each of the world's major forest biomes. Supplementary standardized measurements at subsets of the sites provide additional information on plants, animals, and ecosystem and environmental variables. CTFS-ForestGEO sites are experiencing multifaceted anthropogenic global change pressures including warming (average 0.61 degree C), changes in precipitation (up to plus or minus 30% change), atmospheric deposition of nitrogen and sulfur compounds (up to 3.8 g N m super(-2) yr super(-1) and 3.1 g S m super(-2) yr super(-1)), and forest fragmentation in the surrounding landscape (up to 88% reduced tree cover within 5 km). The broad suite of measurements made at CTFS-ForestGEO sites makes it possible to investigate the complex ways in which global change is impacting forest dynamics. Ongoing research across the CTFS-ForestGEO network is yielding insights into how and why the forests are changing, and continued monitoring will provide vital contributions to understanding worldwide forest diversity and dynamics in an era of global change.

Interactions between invasive and indigenous taxa across trophic levels often tend to propagate throughout the ecosystem, but also those at the same trophic level may affect biodiversity. Here, we examine faunal interactions between an invasive Asian morph of the cerithioidean gastropod Melanoides tuberculata and indigenous gastropods in long-lived Lake Malawi. Studying quantitative samples, we document a negative spatial correlation between the established invader and endemic Melanoides species, and positive ones between invasive and native M. tuberculata, and between native Melanoides and schistosome-transmitting Bulinus. Comparison of modern and fossil samples indicates that Melanoides communities have changed since the middle Holocene from consisting predominantly of endemic taxa (95%) toward a dominance by non-endemics (80%). External evidence suggests that ecosystem change, such as increased sedimentation and eutrophication, and interactions between the invasive and endemic Melanoides species are the most likely causes for these changes. More in-depth study of the benthic ecosystem is required to document interaction mechanisms better, but the invasive taxon is playing an important role in reshaping communities and diversity in Lake Malawi.

DO - http://dx.doi.org/10.1007/s10750-014-2093-0 ER - TY - JOUR T1 - The surface compositions of Pluto and Charon AN - 1656038385; 2015-013742 AB - The surface of Pluto as it is understood on the eve of the encounter of the New Horizons spacecraft (mid-2015) consists of a spatially heterogeneous mix of solid N (sub 2) , CH (sub 4) , CO, C (sub 2) H (sub 6) , and an additional component that imparts color, and may not be an ice. The known molecular ices are detected by near-infrared spectroscopy. The N (sub 2) ice occurs in the hexagonal crystalline beta -phase, stable at T > 35.6 K. Spectroscopic evidence for wavelength shifts in the CH4 bands attests to the complex mixing of CH (sub 4) and N (sub 2) in the solid state, in accordance with the phase diagram for N (sub 2) + CH (sub 4) . Spectra obtained at several aspects of Pluto's surface as the planet rotates over its 6.4-day period show variability in the distribution of CH (sub 4) and N (sub 2) ices, with stronger CH (sub 4) absorption bands associated with regions of higher albedo, in correlation with the visible rotational light curve. CO and N2 ice absorptions are also strongly modulated by the rotation period; the bands are strongest on the anti-Charon hemisphere of Pluto. Longer term changes in the strengths of Pluto's absorption bands occur as the viewing geometry changes on seasonal time-scales, although a complete cycle has not been observed. The non-ice component of Pluto's surface may be a relatively refractory material produced by the UV and cosmic-ray irradiation of the surface ices and gases in the atmosphere, although UV does not generally penetrate the atmospheric CH (sub 4) to interact with the surface. Laboratory simulations indicate that a rich chemistry ensues by the irradiation of mixtures of the ices known to occur on Pluto, but specific compounds have not yet been identified in spectra of the planet. Charon's surface is characterized by spectral bands of crystalline H (sub 2) O ice, and a band attributed to one or more hydrates of NH (sub 3) . Amorphous H (sub 2) O ice may also be present; the balance between the amorphization and crystallization processes on Charon remains to be clarified. The albedo of Charon and its generally spatially uniform neutral color indicate that a component, not yet identified, is mixed in some way with the H (sub 2) O and NH (sub 3) .nH (sub 2) O ices. Among the many known small bodies in the transneptunian region, several share characteristics with Pluto and Charon, including the presence of CH (sub 4) , N (sub 2) , C (sub 2) H (sub 6) , H (sub 2) O ices, as well as components that yield a wide variety of surface albedo and color. The New Horizons investigation of the Pluto-Charon system will generate new insight into the physical properties of the broader transneptunian population, and eventually to the corresponding bodies expected in the numerous planetary systems currently being discovered elsewhere in the Galaxy.

Near-infrared spectral data have revealed Charon's surface to be rich in crystalline water ice and ammonia hydrates. In this work, we search for spectral differences across Charon's surface with new near-infrared spectral data taken in the K-band (2.0-2.4 ?m) with SINFONI on the VLT and NIRI on Gemini North as well as with previously published spectral data. The strength of the absorption band of ammonia hydrate is dependent on the state of the ice, concentration in H (sub 2) O, grain size, temperature and exposure to radiation. We find variability of the band center and band depth among spectra. This could indicate variability of the distribution of ammonia hydrate across Charon's surface. If the spectral variation is due to physical properties of Charon, the New Horizons flyby could find the concentration of ammonia hydrate heterogeneously distributed across the surface. Comparison between this work and New Horizons results will test the limits of ground-based reconnaissance.

These can be categorized into a priori evaluation of the intrinsic fossil evidence, and a posteriori evaluation of congruence through cross-validation. We contrasted these competing approaches and explored the impact of different interpretations of the fossil evidence upon Bayesian divergence time estimation. The results demonstrate that a posteriori approaches can lead to the selection of erroneous calibrations. Bayesian posterior estimates are also shown to be extremely sensitive to the probabilistic interpretation of temporal constraints. Furthermore, the effective time priors implemented within an analysis differ for individual calibrations when employed alone and in differing combination with others. This compromises the implicit assumption of all calibration consistency methods, that the impact of an individual calibration is the same when used alone or in unison with others. Thus, the most effective means of establishing the quality of fossil-based calibrations is through a priori evaluation of the intrinsic palaeontological, stratigraphic, geochronological and phylogenetic data. However, effort expended in establishing calibrations will not be rewarded unless they are implemented faithfully in divergence time analyses.

The version of the algorithm described here includes relevant changes with respect to the operational one, including differences in the reference spectra for H sub(2)CO, the fit of O sub(2)-O sub(2) collisional complex, updates in the high-resolution solar reference spectrum, the use of a model reference sector over the remote Pacific Ocean to normalize the retrievals, an updated air mass factor (AMF) calculation scheme, and the inclusion of scattering weights and vertical H sub(2)CO profile in the level 2 products. The setup of the retrieval is discussed in detail. We compare the results of the updated retrieval with the results from the previous SAO H sub(2)CO retrieval. The improvement in the slant column fit increases the temporal stability of the retrieval and slightly reduces the noise. The change in the AMF calculation has increased the AMFs by 20%, mainly due to the consideration of the radiative cloud fraction. Typical values for retrieved vertical columns are between 4 x 10 super(15) and 4 x 10 super(16) molecules cm super(-2), with typical fitting uncertainties ranging between 45 and 100%. In high-concentration regions the errors are usually reduced to 30%. The detection limit is estimated at 1 x 10 super(16) molecules cm super(-2).

Its strata can be divided into four tectonostratigraphic sequences (TS). TS I is represented by the probably Permian Honeycomb Point Formation and possibly the Lepreau Formation. TS II includes the Wolfville Formation with the probably Middle Triassic Economy Member and the early Late Triassic Evangeline Member. These members have yielded markedly different assemblages of continental tetrapods. TS III comprises most of the Blomidon Formation, which is Norian to Rhaetian in age. The Blomidon Formation has yielded few skeletal remains of tetrapods to date but many tetrapod tracks. TS IV includes the late Rhaetian top of the Blomidon Formation and the McCoy Brook Formation, which overlies the North Mountain Basalt and is latest Rhaetian and earliest Jurassic (Hettangian) in age. The McCoy Brook Formation has yielded a diversity of continental tetrapods and lacks any of the characteristic Late Triassic forms. Recent work has correlated the Global Boundary Stratotype Section and Point (GSSP) for the base of the Jurassic (Hettangian) to a level above the North Mountain Basalt. Thus most of the tetrapod fossils from the McCoy Brook Formation are latest Rhaetian in age, but the higher horizon with skeletal remains of sauropodomorph dinosaurs may be earliest Hettangian in age. The Fundy basin preserves the only known, stratigraphically tightly constrained record of the profound biotic changes in continental ecosystems across the Triassic-Jurassic transition.

This included the bilateral ctenocystoids, which were long thought to be restricted to the Cambrian. Here, we describe a new species of ctenocystoid from the Upper Ordovician of Scotland (Conollia sporranoides sp. nov.). This allows us to revise the genus Conollia, which was previously based on a single poorly-known species from the Upper Ordovician of Wales (Conollia staffordi). Both these species are characterized by a unique morphology consisting of an elongate-ovoid body covered in spines, which clearly distinguishes them from their better-known Cambrian relatives; they are interpreted as infaunal or semi-infaunal burrowers from deep-water environments. This indicates that the ctenocystoid body plan was not fixed early in the evolution of the group, and they most likely modified their structure as an adaptation to a new mode of life in the Ordovician.

Herein, we detail the stratigraphic position of the fossiliferous unit, describe the insect fauna of the Coal Creek locality and document its bias towards very small but remarkably pre-served insects. In addition, the depositional environment is examined and the mineral constituents of the laminations that comprise the varves of the Kishenehn oil shale are defined. Fifteen orders of insects have been recorded with the majority of all insects identified as aquatic with the families Chironomidae (Diptera) and Corixidae (Hemiptera) dominant. The presence of small aquatic insects, many of which are immature, the intact nature of > 90% of the fossil insects and the presence of Daphnia ephippia, all indicate that the depositional environment was the shallow margin of a large freshwater lake. The fossil insects occur within fossilized microbial mat layers that comprise the bedding planes of the oil shale. Unlike the fossiliferous shales of the Florissant and Okanagan Highlands, the mats are not a product of diatomaceous algae nor are diatom frustules a component of the sediments or the varve structure. Instead, the varves are composed of very fine eolian siliciclastic silt grains overlaid with non-diatomaceous, possibly cyanobacteria-derived microbial mats which contain distinct traces of polyaromatic hydrocarbons. A distinct third layer composed of essentially pure calcite is present in the shale of some exposures and is presumably derived from the seasonal warming-induced precipitation of carbonate from the lake's waters. The Coal Creek locality presents a unique opportunity to study both very small middle Eocene insects not often preserved as compression fossils in most Konservat-Lagerstaette and the processes that led to their preservation.

Given this genus's perseverance, Leptaena is a potential source of information regarding survivorship in mass extinctions and can aid in predicting the responses of organisms to the current biodiversity crisis. This study aims to establish the phylogenetic relationships between species of Leptaena and compile occurrences of this genus in the PaleoDB Database. We scored Leptaena species for 36 characters involving internal and external shell features. Then, we conducted a parsimony and maximum likelihood analyses, the latter of which incorporated the stratigraphic data of each taxon in order to derive a complete tree that benefits from the information provided by the fossil record, as well as disparity analyses. Our results show high morphological disparity in the Ordovician with a significant decrease after the end-Ordovician mass extinction which suggests a common evolutionary behavior seen before in other studies where high rates of change occur in the early history of a genus. Assessing the end-Ordovician extinction proved to be more complex due to the possible convergence of younger Leptaena species towards older forms lost during extinction: although parsimony trees suggest many survivors, disparity analyses indicate a major drop of disparity after the Ordovician followed by slow re-expansion recapturing pre-extinction morphospace. Future work will involve the addition of more taxa in order to obtain a more complete tree and properly assess the behavior of evolutionary relationships during the first two Paleozoic mass extinction events. Further goals include investigating the ecologies and phylogenetic relationships between species that survived the end-Ordovician mass extinction, as this may help us to predict survivorship among biomineralizing benthic clades to ongoing global change.

However, Dione lacks the hemispherical symmetry seen on Enceladus's leading and trailing hemisphere tectonized terrains. To date, no detailed fracture mapping of these regions have been completed in conjunction with a detailed characterization of the tectonic structures which comprise the wispy terrains. With this work, we produced detailed fracture maps of the wispy terrains as well as a morphological classification of the structures. Characterization of these structures shows a dearth of diverse structures identified as scarps, twin scarps (likely graben), and troughs. Two additional types of features are classified, but may not be tectonic. While not as heavily tectonically resurfaced as Enceladus, it interesting that Dione's tectonic structures are so limited in morphology where Enceladus's surface shows a wide diversity of tectonic structures. Jupiter's moon Europa is expected to host a global subsurface ocean, similarly hypothesized for Enceladus, the presence of which suggests that nonsynchronous rotation may be occurring, or has occurred in the past. Thus if fracture patterns on Dione are similar to what is predicted due to nonsynchronous rotation, it would suggest that Dione has or had a global subsurface ocean. Using SatStressGUI, we model stresses on Dione's surface due to nonsynchronous rotation and compared the predicted fracture orientations with the distribution of mapped fractures. We find a good first-order match between observed fracture orientation and the orientation of those predicted by SatStressGUI; however, further analysis is required.

The history of activity is commonly preserved in the form of ridge and trough terrains. Ridges can display different morphological forms including a single or double ridge, ridge complex, or a ridge plain, can stand from 10s to approximately 1000 m high, reach widths of 2-20 kilometers, and reach over a thousand kilometers in length. Ridge and trough terrains can be found on moons of each of the outer solar system's planets, but the nature of their formation appears to be varied and complex. These features can preserve past periods of extension, contraction, and/or shearing and may help to determine the thickness and constitutive properties of the upper-most portions of the icy shell. Here, we expand on previous geological mapping of ridges on icy satellites and focus on those found on Enceladus and Europa, to constrain whether the ridges are related to one another in terms of their structure, evolution, and implied formation mechanisms. We create geological maps to assist in the classification of ridge types by comparing basic characteristics, such as planform shape, cross-sectional shape, length, height, width, and slope. The mapping can also identify common geological associations, as well as crosscutting relationships that are used to determine the relative ages of ridges. Ridges that are similar from one moon to the next invite consideration of analogous formation mechanisms. For example, the "tiger stripe" double ridges of the Enceladus South Polar Terrain resemble double ridges on Europa, and are potentially analogous to features observed on Neptune's moon Triton. The morphological similarities and differences among ridges on different icy satellites will help to constrain the tectonic and volcanic histories of the moons and could help to determine if the moons experienced similar evolutionary paths.

Such low CO (sub 2) estimates suggest very low radiative forcing given 3% lower solar luminosity at that time, a condition that may have been magnified by pO (sub 2) -induced higher atmospheric density. The implication of this reduced radiative forcing on the late Paleozoic climate system is strongly debated, in large part due to poorly constrained atmospheric CO (sub 2) estimates. We present an integrated pedogenic carbonate and fossil cuticle reconstruction of atmospheric CO (sub 2) through 16 million years of the latter half of the Pennsylvanian and earliest Permian developed using a cyclothem series in the Illinois Basin as well as a subset of samples from the Appalachian and Donets basins. Overall, reconstructed CO (sub 2) falls below the modeled threshold (560 ppm) for late Paleozoic glacial inception, well within the range of ice sheet stability during the LPIA (up to 840 ppm). The suborbital resolution record reveals CO (sub 2) variations between approximately 200 and 700 ppm with an apparent long eccentricity pacing. Short-term CO (sub 2) fluctuations are superimposed on a 106-yr CO (sub 2) trend that varies in-step with major sea level changes and glacial advances and retreats inferred from Donets Basin and Midcontinent stratigraphic trends. Comparison of the CO (sub 2) reconstruction and inferred sea level with published paleobotanical records for tropical Pangaea suggests a mechanistic relationship between CO (sub 2) , glaciation, and major shifts in lowland vegetation, highlighting the important role terrestrial carbon storage likely played in creating the hierarchy of atmospheric CO (sub 2) fluctuations. Specifically, substantial changes in floral composition of paleotropical lowlands within eccentricity glacial-interglacial cycles occurred coincident with 200 to 300 ppm fluctuations in CO (sub 2) . Additionally, three ecologic thresholds in the Pennsylvanian were coincident with major CO (sub 2) shifts suggesting a strong role for CO (sub 2) -forcing of these ecologic events, whether indirectly through its influence on climate or directly through physiological consequences for photosynthesis and plant viability.

The differences between the active south and ancient north may be related to differences in ice shell thickness, depth to liquid water, and/or energy flux and how these characteristics have changed through time. The formation, morphological characteristics, and subsequent modification of geologic structures observed in both hemispheres provide an opportunity to constrain the geologic history of the ice shell. In this work, we focus on the formation of Enceladus's ridges that are morphologically similar to features observed on other icy satellites, in particular those on Europa. First, we characterize the structure and morphology of different types of ridges on Enceladus and map their locations using Cassini data. For ridges showing similar morphological characteristics for both Enceladus and Europa, we investigate formation mechanisms proposed for Europa, within the context of measured Enceladus ridge morphologies and expected range of ice shell thickness. We model proposed formation mechanisms including a crystallizing shallow water body (e.g. Johnston and Montesi, 2014) and a shallow water sill intrusion invoking flexure and flanking fractures at the surface (e.g. Dombard et al., 2013). Models consider fracturing processes, heat transfer, induced thermal regimes and fluid flow in order to provide insight into ridge building, lithostatic flexure and the required physical parameters of the ice shell including thickness and induced stresses. These models can therefore provide a greater understanding of ridge formation and ice shell characteristics at Enceladus. Additionally, as processes may be similar on other icy bodies with shallow liquid water, including Europa, the models can also give insight into ridge building processes and ice shell characteristics on icy bodies in general.

AN - 1832722721; 2016-091621 AB - Ediacaran ecosystems are thought to have been relatively 'simple' compared to those of the Paleozoic, comprising few interspecific biotic interactions and few unique modes of nutrient acquisition. Establishing the feeding modes of Ediacaran organisms is thus critical to determining the complexity of Ediacaran ecosystems; however, inferring feeding strategies has long proven problematic because many Ediacarans are characterized by body plans that lack clear modern analogues. Here, we use computational fluid dynamics (CFD) to rigorously analyze the hydrodynamic behavior of the iconic Ediacaran organism Tribrachidium heraldicum, thereby testing between hypothesized feeding modes. We show that the external morphology of Tribrachidium passively directs water flow towards the apex of the organism, and generates low-velocity eddies above apical 'pits'. These patterns of current flow support the interpretation of Tribrachidium as a passive suspension feeder, and thus provide evidence for suspension feeding approximately 10 million years before the Cambrian. We further test the hypothesis that Ediacaran communities were surprisingly complex by analyzing Ediacaran through early Cambrian benthic communities using rank abundance distributions (RADs), which reflect community complexity (i.e., the number and division of available resources, and the diversity of ecological guilds). We find that the proportion of 'complex' vs. 'simple' community RADs remains largely equivalent through the Ediacaran and Cambrian, with the exception of the latest Ediacaran (Nama assemblage), consistent with an end-Ediacaran extinction ('biotic replacement') scenario. Our combined results demonstrate that the Ediacara biota formed ecosystems in the latest Precambrian with equivalent complexity to those that characterized the Cambrian, and suggests hidden ecological diversity among Ediacaran problematica.

Despite these efforts, the PTB interval remains poorly resolved in the terrestrial realm. Here we present new data from the re-investigation of four terrestrial PTB sections from western Guizhou and eastern Yunnan. Paleoenvironment study of the PTB transition was done using sedimentological analysis, paleobotany, palynology and XRF. Our results show major differences in the depositional settings between the Xuanwei and Kayitou formations. Changes from terrestrial fluvial-lacustrine to coastal marine setting are observed, with a clear segregation supported by our combined dataset. Exact stratigraphic placement of the PTB remains unclear, although current data indicates that the PTB is likely occurring at the top of the Xuanwei Fm. Recent radiometric dates bracketing the PTB from the Meishan GSSP are within range of bed 68 at Chahe. The disappearance of the Gigantopteris flora cannot be used as a marker for the EPE as this plant group persist into the Triassic. However, plant fossils reveal two distinct assemblages: A Late Permian (Changhsingian) Gigantonoclea guizhouensis-Annularia pingloensis assemblage in the upper Xuanwei Formation, and an Early Triassic (Induan) Annalepis-Peltaspermum assemblage associated with relicts of Permian gigantopterids in the uppermost Xuanwei and basal Kayitou formations. The Early Triassic age of the Kayitou Formation is further supported by the occurrence of typical Triassic marine fauna. Around 15% of the 116 collected and analyzed palynological samples yielded an extremely low recovery of palynomorphs, the remaining were barren. Palynological assemblages are almost exclusively composed of spores, while three pollen grain were also identified. A approximately 1 meter zone with fungal spores including Reduviasporonites has been identified near the top of the Xuanwei Fm. This interval may correspond to the EPE "fungal spike" conventionally associated to ecosystem collapse. It is yet to demonstrate whether diversity changes are related to paleoenvironmental change coeval the transition between the Xuanwei and Kayitou formations, or rather linked to the EPE.

Its strata can be divided into four tectonostratigraphic sequences (TS). TS I is represented by the probably Permian Honeycomb Point Formation and possibly the Lepreau Formation. TS II includes the Wolfville Formation with the probably Middle Triassic Economy Member and the early Late Triassic Evangeline Member. These members have yielded markedly different assemblages of continental tetrapods. TS III comprises most of the Blomidon Formation, which is Norian to Rhaetian in age. The Blomidon Formation has yielded few skeletal remains of tetrapods to date but many tetrapod tracks. TS IV includes the late Rhaetian top of the Blomidon Formation and the McCoy Brook Formation, which overlies the North Mountain Basalt and is latest Rhaetian and earliest Jurassic (Hettangian) in age. The McCoy Brook Formation has yielded a diversity of continental tetrapods and lacks any of the characteristic Late Triassic forms. Recent work has correlated the Global Boundary Stratotype Section and Point (GSSP) for the base of the Jurassic (Hettangian) to a level above the North Mountain Basalt. Thus most of the tetrapod fossils from the McCoy Brook Formation are latest Rhaetian in age, but the higher horizon with skeletal remains of sauropodomorph dinosaurs may be earliest Hettangian in age. The Fundy basin preserves the only known, stratigraphically tightly constrained record of the profound biotic changes in continental ecosystems across the Triassic-Jurassic transition.

Added to the sites drilled in 2007 and 2008, the new boreholes confirm the common excellent preservation of planktonic and benthic foraminifera and calcareous nannofossils from core samples that will be used for biostratigraphy, evolutionary studies, paleoceanography and climatic reconstructions from the Tanzanian margin, with implications elsewhere. The new sites verify the presence of a relatively expanded Upper Cretaceous succession in the region that has allowed a new stratigraphic unit, named here as the Lindi Formation (Fm), to be formally defined. The Lindi Fm (upper Albian to Coniacian), extending approximately 120 km between Kilwa and Lindi, comprises a 335-m-thick, outer-shelf to upper-slope unit, consisting of dark gray claystone and siltstone interbeds, common finely-laminated intervals, minor cm-thick sandstones and up to 2.6% organic carbon in the Turonian. A subsurface, composite stratotype section is proposed for the Lindi Fm, with a gradational top boundary with the overlying Nangurukuru Fm (Santonian to Maastrichtian) and a sharp bottom contact with underlying upper Albian sandstones. The section cored at TDP Sites 36 and 38 belongs to the Lindi Fm and are of lower to middle Turonian age (planktonic foraminifera Whiteinella archaeocretacea to Helvetoglobotruncana helvetica Zones and nannofossils subzones UC6b + or - UC7). The lower portion of TDP Site 39 (uppermost part of the Lindi Fm) is assigned to the lower to upper Coniacian (planktonic foraminifera Dicarinella concavata Zone and nannofossils zone UC 10), while the remaining part of this site is attributed to the Coniacian-Santonian transition and younger Santonian (planktonic foraminifera D. asymetrica Zone and upper part of nannofossils zone UC10). TDP Site 37 recovered relatively expanded (150 m thick), monotonous calcareous claystones from the lower to upper Maastrichtian (planktonic foraminifera Pseudoguembelina palpebra to Abathomphalus mayaroensis Zones and nannofossils zones UC19 to UC20a (super TP) ) that were separated by a hiatus and/or a faulted contact from overlying brecciated carbonates of the Selandian (middle Paleocene: PF Zone P3 and nannofossil zone NP5). The lower portion of TDP Sites 40A and 40B recovered sandstones and conglomerates barren of microfossils. Their overlying parts were assigned to incomplete sections of the nannofossil zones NC6A to NC8 (uppermost Barremian to lower Albian). Benthic foraminiferal assemblages allowed the Barremian to lower Aptian to be identified in TDP Sites 40A and 40B, while the upper Aptian to middle Albian (Hedbergella trocoidea to Ticinella primula Zones) were assigned using planktonic foraminifera. Cores recovered at TDP 39 (Coniacian-Santonian) and at TDP Sites 40A and 40B (Barremian-middle Albian) represent the first time that these two intervals have been continuously cored and publicly documented in Tanzania. Bulk sediment isotope records generated for the new sites show lower delta (super 18) O (sub carb) values in the Turonian and Santonian ( approximately -3.5 ppm to -5 ppm) than in the Maastrichtian ( approximately -3 ppm), a situation consistent with extreme global warmth in the older intervals and cooling toward the end of the Cretaceous. Also, similar to Turonian sites from previous TDP expeditions, a negative delta (super 13) C (sub org) excursion was detected across the W. archaeocretacea-H. helvetica boundary of TDP Site 36 (close to, but above, the Cenomanian-Turonian boundary). This excursion probably responded to local processes in the region, but it is unknown whether they were related to the recovery phase from Ocean Anoxic Event 2.

We explore differences in atmospheric parameters and elemental abundances caused by the use of the linelist developed for the Gaia-ESO Survey (GES) compared to one based on Arcturus used in our previous work. [Fe/H] values decrease when using the GES linelist instead of the Arcturus-based linelist; these differences are probably driven by systematically lower (��0.1 dex) GES surface gravities. Using the GES linelist we determine abundances for 10 elements-Fe, Mg, Si, Ca, Ti, Na, Ni, Zr, Ba, and La. We find the cluster�s average metallicity [Fe/H] = 0.03 + or - 0.07 dex, in good agreement with literature values, and a lower [Mg/Fe] abundance than has been reported before for this cluster (0.11 + or - 0.05 dex). We also find the neutron-capture element barium to be highly enhanced-[Ba/Fe] = +0.48 + or - 0.08-and disparate from cluster measurements of neutron-capture elements La and Zr (�0.08 + or - 0.05 and 0.08 + or - 0.08, respectively). This is in accordance with recent discoveries of supersolar Ba enhancement in young clusters along with more modest enhancement of other neutron-capture elements formed in similar environments.

Studies over the past approximately 20 years have interpreted jadeitite either as the direct hydrous fluid precipitate from subduction channel dewatering into the overlying mantle wedge or as the metasomatic replacement by such fluids of oceanic plagiogranite, graywacke, or metabasite along the channel margin. Thus, jadeitites directly sample and record fluid transport in the subduction factory and provide a window into this geochemical process that is critical to a major process in the Earth system. They record the remarkable transport of large ion lithophile elements, such as Li, Ba, Sr, and Pb, as well as elements generally considered more refractory, such as U, Th, Zr, and Hf. Jadeitite is also the precious form of jade, utilized since antiquity in the form of tools, adornments, and symbols of prestige.

Apparent morphological convergence is often explained as the result of adaptation to similar ecological niches. However, quantitative tests of this hypothesis are uncommon. We use dietary data to classify the feeding ecology of extant marine tetrapods and identify patterns in skull and tooth morphology that discriminate trophic groups across clades. Mapping these patterns onto phylogeny reveals coordinated evolutionary shifts in diet and morphology in different marine tetrapod lineages. Similarities in morphology between species with similar diets-even across large phylogenetic distances-are consistent with previous hypotheses that shared functional constraints drive convergent evolution in marine tetrapods.

Volcanoes are compelling evidence that the Earth is a dynamic planet characterised by endless change and renewal. Humans have always found volcanic activity fascinating and have often chosen to live close to volcanoes, which commonly provide favourable environments for life. Volcanoes bring many benefits to society: eruptions fertilise soils; elevated topography provides good sites for infrastructure (e.g. telecommunications on elevated ground); water resources are commonly plentiful; volcano tourism can be lucrative; and volcanoes can acquire spiritual, aesthetic or religious significance. Some volcanoes are also associated with geothermal resources, making them a target for exploration and a potential energy resource. Much of the time volcanoes are not a threat because they erupt very infrequently or because communities have become resilient to frequently erupting volcanoes. However, there is an ever-present danger of a long-dormant volcano re-awakening or of volcanoes producing anomalously large or unexpected eruptions. Volcanic eruptions can cause loss of life and livelihoods in exposed communities, damage or disrupt critical infrastructure and add stress to already fragile environments. Their impacts can be both short-term, e.g. physical damage, and long-term, e.g. sustained or permanent displacement of populations. The risk from volcanic eruptions and their attendant hazards is often underestimated beyond areas within the immediate proximity of a volcano. For example, volcanic ash hazards can have effects hundreds of kilometres away from the vent and have an adverse impact on human and animal health, infrastructure, transport, agriculture and horticulture, the environment and economies. The products of volcanism and their impacts can extend beyond country borders, to be regional and even global in scale. Although known historical loss of life from volcanic eruptions (since 1600 AD about 280,000 fatalities are recorded, Auker et al. (2013)) is modest compared to other major natural hazards, volcanic eruptions can be catastrophic for exposed communities. In 1985 the town of Armero in Colombia was buried by lahars (volcanic mudflows) with more than 21,000 fatalities due to relatively small explosive eruptions at the summit of Nevado del Ruiz volcano that partially melted a glacier (Voight, 1990).

During the Oligocene and early Miocene this resulted in uplift of the Eastern Cordillera, and in the middle Miocene closure of the Panama Isthmus. From about this time the Cordillera started acting as orographic barrier for Atlantic humid atmospheric masses. This situation led to major changes in the South American paleogeography, among which the onset of the transcontinental Amazon River, and is thought to have formed the basis for modern patterns of biodiversity in Andes and Amazonia. Parallel to this process, and at least from Eocene to late Miocene, large parts of western Amazonia were affected by estuarine conditions with varying degrees of salinity. In this paper I will discuss some aspects of our multidisciplinary research on a borehole in the Amazon submarine fan, providing key insights into the timing of onset of the Amazon River, and discuss different scenarios for the Plio-Pleistocene landscape in the Amazon drainage basin.

Preliminary results from a pilot study on the Pacific and Caribbean coasts of Panama AN - 1803773035; 2016-062393 AB - Spatial and temporal gradients in individual body size, both within and across species, are a prominent feature of the marine invertebrate fossil record. However it is not always clear what environmental factors, if any, control such size gradients. Primary productivity differences are commonly invoked, but due to the lack of reliable proxies for local primary productivity this hypothesis can be difficult to test. Moreover, modern data on marine invertebrate local body size distributions are relatively scarce, especially in the benthic shelf environments that dominate the continental fossil record. To elucidate environmental controls on local body size distributions we have begun to tabulate molluscan size-frequency data from modern subfossil death assemblages. We take advantage of a large productivity gradient in the Central American tropics: the Pacific coast of Panama, especially the Gulf of Panama, is a strongly seasonal high-productivity setting, whereas the Caribbean coast is dominated by oligotrophic conditions with little seasonal variation. Initial analyses comparing Pacific and Caribbean dredge samples are surprising: mean individual size of both gastropods and bivalves is much larger in the Caribbean than in the Pacific. The pattern holds up at the whole-community level, within most trophic groups and even within congenerics. This contrast does not appear to be explained by differences in shell destruction rate, but may be influenced by higher mortality rates and faster turnover in the Pacific due to natural predation and/or recent human impacts. Despite the larger mean size of Caribbean individuals the overall abundance of shells is much higher in Pacific samples so that estimates of whole-community energetic demand are positively correlated with productivity. To better understand the controls on body size gradients, future work will focus on sampling different environments along each coast, dating shells to assess degree of time-averaging, and comparing growth rates within those genera that occur in both Pacific and Caribbean samples.

The maximum size across all life has increased by approximately 20 orders of magnitude and the mean size by perhaps ten. At the broadest temporal scale, there were two punctuations in size increase associated with increases in complexity as eukaryotic cells evolved from prokaryotic cells approximately 1.9 Ga and as multicellular life diversified from unicellular ancestors approximately 0.6 Ga. However, the quantitative relationship between organism size and structural complexity remains poorly documented. We assessed the relationship between complexity and size using a dataset that includes organism size (biovolume) and hierarchical level of complexity (degrees of aggregation and individuation; McShea 2001) for more than 34,000 genera spanning all three domains of the tree of life as well as the entire Geozoic. The distributions of sizes within each of the hierarchical levels show two key patterns. First, the mean size of genera within each hierarchical level of complexity is, on average, one to three orders of magnitude larger than at the next lower level. Second, there is no overlap at the extremes of the size distributions between hierarchical levels. Third, the range of possible sizes increases from one level of hierarchical organization to the next. Together, size data spanning the tree of life provide the first quantitative support for previously suggested evolutionary expansion away from a left wall of minimal size and complexity as well as a rescaling of the right wall of maximal size concomitant with structural innovation. In addition, size data provide clear evidence that although higher levels of structural complexity enable larger maximum sizes and a wider range of sizes, they also rescale the left wall of minimum size. Given the fundamental functional importance of size, the tradeoffs between size and complexity illustrate why structural innovations have never led to the competitive exclusion of less structurally complex classes of organisms.

For example, many studies have documented an expansion of the body size niche by mammals after the K/Pg extinction, which is widely thought to have resulted from ecological release after the extinction of the non-avian dinosaurs. Here, we examine the evolution of body size in 4 clades of terrestrial vertebrates (dinosaurs, mammals, pterosaurs, and birds) by compiling data for 3684 species (63 pterosaurs, 45 birds, 3035 mammals, and 541 non-avian dinosaurs) spanning the last 250 million years (Triassic-Holocene). Although dinosaurs and mammals originated at roughly the same time ( approximately 210-220 Ma), dinosaurs quickly expanded their body size niche and filled most ecological roles in terrestrial communities, whereas contemporaneous (Mesozoic) mammals remained restricted to small-bodied species (<10-15 kg) and inhabited a limited set of ecological roles. Unlike the evolution of body size in mammals, which is consistent with a driven trend, the evolution of body size in dinosaurs is consistent with a random walk. Flying organisms show a different pattern. Pterosaurs evolved during the Mesozoic and remained fairly small ( approximately 1 kg) for the first 100 Ma of their evolution. However, after birds evolved, pterosaurs underwent a driven shift to larger size with birds occupying the smaller body size niche. After the extinction of the pterosaurs and the non-avian dinosaurs, mammals rapidly expanded their body size niche and birds underwent a driven shift to larger size.

The farmers' strategies reflect their increasing disillusionment and mistrust regarding external actors and reproduce a "moral economy of disorder" in local political culture. The author's personal entanglement in the case study highlights the challenges raised in engaged ethnography.//À l'aide d'une étude de cas détaillée du travail d'une ONG locale en Guinée-Bissau et des différents rôles que jouent les acteurs concernés, cet article montre à quel point les oppositions binaires conventionnelles entre domination et résistance, donateurs tout puissants au Nord et organisations locales de développement sans défense, ou encore entre État et société civile sont inadéquates. Les stratégies des paysans sont le reflet de leur désillusion grandissante et de leur défiance vis-à-vis des donateurs externes, tout en reproduisant une « économie morale du désordre » dans la culture politique locale. La façon dont l'auteure a été prise à partie dans cette étude de cas met en lumière, en outre, les défis d'une ethnographie engagée.

Most PPP studies have focused on a single taxonomic group or a distinct metric of environmental or ecological change. Here we present the Tropical America Paleobiology Database designed to assist in the synthetic analyses of all PPP data. The relational database will collate quantitative taxonomic, ecological and functional biotic data within stratigraphic and geochronological context for comparison with environmental data as derived from high-resolution geochemistry from marine ecosystems and their communities. Users will have rapid access to a large range of standardized information, facilitating detailed analysis on fossil and recent organisms to explore and test patterns of biotic and environmental change in tropical marine ecosystems over geological time. The Database will allow downloads and direct analyses to be performed on its contents, interactive access for browsing the contents and formulating specific queries. We describe the benefits of a unified stratigraphic, biotic, geochemical and environmental dataset, and present a test case of how the database can explore drivers of biotic turnover and ecological change.

This presentation highlights results of an integrated study of planktonic foraminifera and calcareous nannofossils species abundance distributions and stratigraphic ranges in shallow boreholes that were drilled during the Tanzania Drilling Project (TDP) with comparisons to a coeval deep-sea sequence drilled in the southeast Indian Ocean. Major species turnovers occur at different levels in the upper Turonian for both calcareous plankton groups. The older of these turnovers occurs at the top of the Hv. helvetica Zone, where last occurrences of four planktonic foraminiferal species are immediately followed, within several meters, by first occurrences of five foraminiferal species. There is essentially no change across this same interval among the calcareous nannofossil populations or in sediment lithology, suggesting that if a hiatus were present, it was very brief. Instead, an accompanying increase in the abundance of dwarfed planktonic forms suggests that the foraminiferal turnover may have been at least partly influenced by a shift in environmental conditions of the surface mixed layer. The subsequent late Turonian turnover is marked by extinction of three calcareous nannofossil species with no co-occurring foraminiferal extinctions and is immediately followed by first appearances of four calcareous nannofossil and two planktic foraminifer species, an abrupt and dramatic increase in the relative abundance of biserial taxa, and a sudden diagenetic shift that results in calcareous infilling of all foraminiferal tests. Comparison between the TDP planktonic foraminiferal species distributions in a mesotrophic shelf break setting with Ocean Drilling Project Hole 762C in an oligotrophic open ocean setting reveals a greater environmental influence species distributions than expected, resulting in significant differences in stratigraphic ranges and relative abundances for more environmentally sensitive species.

Precipitation regimes changed in many regions. Megafossils from the northern Rocky Mountains show high rates of extirpation of local plant populations during the PETM. 88% (46 of 52) of the taxa present in the last 100 kyr of the Paleocene do not occur in the PETM. Of the 6 taxa that range through the PETM, 4 only occur in the last part of the hyperthermal when temperature and CO (sub 2) declined and precipitation increased. Almost 90% of late Paleocene plants do have post-PETM occurrences in the region, demonstrating these taxa survived the event elsewhere. The northern Rockies also experienced high levels of immigration during the PETM, with 77% (20 of 26) of PETM taxa having no Paleocene occurrences in the region. Some PETM immigrants occur in the Paleocene of Europe and southern North America, suggesting large range changes. Only a few PETM immigrants persisted in the northern Rockies following the event. Outside the northern Rockies PETM floral changes were more subtle, but have only been documented by pollen and/or biomarkers which have lower taxonomic resolution and a greater chance of being reworked than do megafossils. Palynofloras do not show high rates of local extirpation during the PETM, but high-latitude sites do record range extensions of plants from lower latitudes. Cupressaceous conifers decreased in high northern latitudes and Podocarpaceae probably declined in high southern latitudes. Decreased conifer abundance at high latitudes, where precipitation likely increased, may show they were less able than angiosperms to take advantage of higher temperatures and/or CO (sub 2) . During the PETM tropical floras began a major increase in diversity, possibly reflecting evolutionary diversification in many separate angiosperm lineages. Plants survived the PETM without major extinction, perhaps surprising given the rate and magnitude of environmental change, and massive changes in distribution and abundance. Given the parallels between the PETM and the Anthropocene, the absence of a plant mass extinction is good news, but it is critical to note that current global change is possibly ten times faster, and that climate is far from the only problem facing plant populations.

Extinction preferentially selected against taxa adapted to nutrient-rich environments uncommon in the SWC today, but the turnover acme occurred 1-2 myr after the final closure of the CAI, which is coincident with the onset of severe NHG. We use approximately 3000 new stable isotope measurements of approximately 60 serially-sampled gastropods (Conus and Strombus) from Costa Rica and Panama to examine nutrient delivery by upwelling and freshwater input during and after the final closure of the Central American Isthmus approximately 3.5 Ma. Gastropod delta (super 18) O profiles were referenced to an open-ocean baseline using delta (super 18) O values for planktonic foraminifera that lived near the same depth. Foraminiferal delta (super 18) O data for the Plio-Pleistocene were derived from sediment cores ODP 999A, DSDP 502B, and MD03-2628 in the Caribbean, and ODP 1242 in the Pacific. Deviation of delta (super 18) O profiles from baseline values allows quantification of seasonal upwelling and freshening in the nearshore environments. delta (super 18) O profiles of fossil shells do not show the strong upwelling and freshening signals found in modern Pacific Conus profiles. However, SWC specimens older than approximately 2.5 Ma show delta (super 18) O ranges greater than those of modern specimens, suggesting potential refugia where seasonal upwelling and/or freshening enhanced productivity. The baseline approach points to significantly greater freshening from 2.5-3.6 Ma and no upwelling after 3.5 Ma. The freshening signal in SWC shells declines after 2.5 Ma, signaling a decline in nutrient delivery and providing a causal mechanism for delayed extinction in the SWC.

The relationship between canopy closure and warming is of interest to paleobotanists and paleoclimatologists alike, because forests significantly impact both regional and global climates. Forests regulate water cycling on continents and maintain the warm, moist conditions to which they are best adapted. The carbon isotope "canopy effect" reflects the extent of canopy closure, and is well documented in delta 13C values of leaves in modern forests. To test the extent of canopy closure among the oldest documented angiosperm tropical forests, we analyzed isotopic characteristics of leaf fossils from the Guaduas and Cerrejon Formations. The Guaduas Fm. (Maastrichtian) contains some of the earliest angiosperm fossils in the Neotropics, and both leaf morphology and pollen records at this site suggest open-canopy structure. The Cerrejon Fm. (Paleocene) contains what are believed to be the first recorded fossil leaves from a closed-canopy forest. We analyzed the carbon isotope content of fossil leaves (n=199) representing ten families of eudicots (Apocynaceae, Bombaceae, Euphorbaceae, Fabaceae, Lauraceae, Malvaceae, Meliaceae, Menispermaceae, Moraceae, Sapotaceae). We interpreted extent of canopy coverage based on the range of delta 13C values. The narrow range of delta 13C values in leaves from the Guaduas Fm. (2.7 ppm) is consistent with an open canopy. For one site in the Cerrejon Fm. a significantly wider range in values (6.3 ppm) suggests a closed-canopy, which contrasts with a narrow range (3.3 ppm) from a site representing a lacustrine facies. The narrow range is consistent with a forest edge, as suggested by the taxa in the leaf assemblage, and consistent with modern studies that show leaves in lake sediments tend to be biased toward plants living at the lake edge. Such environments do not experience closed-canopy conditions, and express the isotopic characteristics associated with an open canopy. This study confirms the identity of the first closed-canopy forest in the geologic record via isotopic analysis and indicates this forest structure developed sometime following the K-Pg mass extinction, and prior to Eocene hyperthermal events, including the PETM.

AN - 1800395895; 2016-055504 AB - A common motivation among ecologists and evolutionary biologists is measuring and explaining biological diversity. evolutionary biologists turn to phylogenetic methods to address diversity-related questions, but paleontologists warn that methods that do not use fossil data make dangerous, often false, assumptions. Unfortunately, the fossil record itself is incomplete, making empirical studies of paleoecology difficult. Paleontological data show species geographic range sizes to be heritable and that some lineages have a higher propensity to speciate than others, resulting in greater standing diversity. These tendencies bear implications for the long-term survival of the lineages that possess them. Here, we use the current phylogenetic method of likelihood-based ancestral state reconstruction (ASR) on genera in the Rosales (Angiosperms: Eudicots) to infer paleo-patterns of species richness and geographic range size. We then ground-truth our investigation against the known fossil record of these genera. Our primary goal is to evaluate the efficacy of ASR to recover paleo-patterns in studies on groups with poor fossil records (unlike the Rosales, which do). Preliminary results using BiSSE-ASR (BiSSE = Binary State Speciation and Extinction) at inferring paleorichness and paleorange size are not statistically significantly better than random guessing. However, because ASR reconstructs common ancestors while paleobotanists are hesitant to assign fossils to cladograms unless they belong to living genera, the failure of ASR may owe in part to the incomplete fossil record than to ASR. Another ASR algorithm, BioGeoBEARS, is capable of incorporating both living and fossil data into its analysis, and for the Rosales likely offers a better reconstruction of the past. Final results of BiSSE-ASR (modern data only) will be compared to those of BioGeoBEARS (modern and fossil data) at the meeting.

Though the PETM clearly reflects a massive carbon release, atmospheric concentrations of CO (sub 2) (pCO (sub 2) ) during the event are loosely constrained. Here we describe new estimates of PETM pCO (sub 2) made using the stomatal index proxy. We developed a new stomatal index calibration curve from living Ginkgo biloba and applied it to fossils of Ginkgo adiantoides from the late Paleocene and early Eocene of Wyoming, estimating that pCO (sub 2) increased from approximately 330 to approximately 550 ppm in the 100 ka preceding the CIE. This coincides with an estimated pre-PETM 5 degrees C temperature rise documented in delta 18O of mammal tooth enamel and fossil leaves from the Bighorn Basin. Ginkgo adiantoides is absent from the PETM, but returns just after the recovery phase of the CIE, and indicates that pCO (sub 2) levels returned to approximately 550 ppm before dropping in the early Eocene. To make stomatal index-based pCO (sub 2) estimates for the PETM, we extracted dispersed cuticle from a plant macrofossil site deposited during the early recovery phase of the CIE. Two morphotypes of dispersed cuticle recovered from the PETM are similar to cuticle removed from late Paleocene macrofossils of Platanites raynoldsii, a member of the sycamore family (Platanaceae). Epidermal features shared by the dispersed cuticle morphotypes and Platanites raynoldsii are typical of modern and fossil Platanaceae. They include a raised oval ledge surrounding a sunken stomatal pore, surface striations oriented perpendicular to the stomata, a relatively uncutinized oval zone around the raised ledge, elongated glandular trichomes on veins, round intercostal trichome bases, and puzzle-piece shaped epidermal cells. The numerous surface striations most resemble those of living Platanus orientalis, a Middle Eastern tree that grows along streams in seasonally dry habitats, conditions similar to those in Wyoming during the PETM. We then compared stomatal index values of the dispersed platanoid cuticle fragments with those of the late Paleocene Platanites raynoldsii to estimate relative change in pCO (sub 2) from the latest Paleocene to the early recovery phase of the CIE.

To date, all hgcAB+ microbes tested are capable of methylating mercury, while organisms lacking hgcA and hgcB are not. This predictability, along with the highly conserved nature of the cobalamin-binding domain in hgcA and the ferrodoxin domain in hgcB means that hgcAB should serve as a biomarker for Hg methylation in nature. Here we provide an overview of method development of qualitative and quantitative polymerase chain reaction (PCR) primers for these genes. Our approach has been to develop a universal set of DNA primers for qualitative evaluation of organismal diversity, plus a set of clade-specific qPCR primers. A universal degenerate primer set was developed that binds the most highly conserved regions in hgcA and B. The primers amplify a long product that can be sequenced for organismal identification, and also provide confirmation that both genes are present and adjacent. The primers were designed using hgcAB sequences from the approximately 100 hgcAB+ organisms with published genomes including Deltaproteobacteria, Firmicutes, and methanogenic Archaea. Primers and reaction conditions were then evaluated (and modified) by testing against more than 30 pure cultures including methylators and non-methylators in all of the clades containing hgcAB+ organisms. Clade-specific qPCR (Deltaproteobacteria, Firmicutes, and methanogens) primers were developed using the same approach. Quantitative PCR requires amplification of shorter sections of DNA. Since the hgcA sequence outside the cobalamin-binding domain is more variable among clades, qPCR required the development of separate primers for each major group. To ensure the primers and reaction conditions are robust and sensitive in complex environmental matrices, we tested the primers on natural samples spiked with mixtures of hgcAB+ cultures. Finally, copy number and diversity information obtained from hgcAB primers were compared to 16S rRNA diversity, and to hgcAB in metagenomic analysis in the same samples. We will show some early data on use of these primers to evaluate relationships between hgcA abundance, Hg-methylation, and terminal electron acceptor availability.

The degradation state of the crater has been studied using Mars Reconnaissance Orbiter and Opportunity rover data. Exposed rim segments rise approximately 10 m to approximately 100 m above the level of the embaying Burns Formation and the crater is 200-500 m deep with the southern interior wall exposing over approximately 300 m relief. Both pre-impact rocks (Matijevic Formation) and Endeavour impact ejecta (Shoemaker Formation) are present at Cape York, but only the Shoemaker crops out (up to approximately 140 m) along the rim segment from Murray Ridge to Cape Tribulation. Study of pristine complex craters Bopolu and Tooting, and morphometry of other martian complex craters, enables us to approximate Endeavour's pristine form. The original rim likely averaged 410 m + or -200 m in elevation and a 250-275 m section of ejecta (+ or -50-60 m) would have composed a significant fraction of the rim height. The original crater depth was likely between 1.5 km and 2.2 km. Comparison between the predicted original and current form of Endeavour suggests approximately 100-200 m rim lowering that removed most ejecta in some locales (e.g., Cape York) while thick sections remain elsewhere (e.g., Cape Tribulation). Almost complete removal of ejecta at Cape York and minimal observable offset across fractures indicates current differences in rim relief are not solely due to original rim relief. Rim segments are embayed by approximately 100-200 m thickness of plains rocks outside the crater, but thicker deposits lie inside the crater. Ventifact textures confirm ongoing eolian erosion with the overall extent difficult to estimate. Analogy with degraded Noachian-aged craters south of Endeavour, however, suggests fluvial erosion dominated rim degradation in the Noachian and was likely followed by approximately 10s of meters modification by alternate processes. Such degradation is consistent with 1) the interpretation of a pediment on the rim flanks of Endeavour, 2) the formation of features such as Marathon Valley, 3) the nearly complete removal of ejecta at Cape York, 4) preservation of a thicker section of ejecta at Cape Tribulation and perhaps, 5) the origin of some gaps in the rim around the crater. A paucity of debris shed from the rim indicates most degradation occurred prior to embayment by the plains rocks.

These profiles are expressive of low sea-stand upland conditions spanning OIS-3 and OIS-2. The profile data illustrate how northern hemisphere climatic variation, isostatic change, and landscape formation processes are expressed within the unglaciated coastal plain south of the Laurentide ice sheet. Five stratigraphic paleosols have revealed detailed information for the intervals dated to approximately 20,000, approximately 24,000, approximately 30,000, approximately 35,000, and approximately 42,000 calendar years BP. Plant-macro remains, phytoliths, and pollen for each interval have been established. One locality, containing multiple stratified paleosols, has produced in situ archaeological remains within a buried surface dated to 17,133+ or -88 c14 years BP (20,525+ or -341 calBP). Our research indicates that regional cool late Pleistocene climatic conditions resulted in the long-term preservation of vitrified charcoal. These circumstances inhibit our ability to rectify the "true" antiquity of in situ archaeological remains. In sum, mixed accumulations of vitrified charcoal from merged and/or welded OIS-3 through OIS-2 age paleosols can result in c14 or AMS-age averaging. The age-averaging can also impede our understanding and timing of late Pleistocene upland aeolian events.

There are multiple stakeholders with different needs for access and accountability for fossils and data related to fossil specimens. Researchers seek uncomplicated access to fossil localities to collect and examine fossils regardless of where they were collected. Federal land managers have the legal obligation to manage fossil locality access to ensure the long-term preservation of the localities and fossils and fulfill federal property management requirements. Specimen repositories are held in public trust to provide long-term care of fossils and ensure that information about the collections is available in accessible data formats. The fossil data we manage should satisfy requirements of multiple stakeholders who have different needs for access and accountability for fossils and data related to fossil specimens. The Smithsonian National Museum of Natural History (NMNH) has been managing fossils collected from public lands since its founding. Its role in fossil resource management is unique as it houses the National Fossil Collection, it supports in-residence, top-tier paleontological curators who actively produce peer reviewed scientific discoveries, and it is a Trust Instrumentality of the United States. In essence, the NMNH Paleo Dept. represents multiple stakeholder groups that have an interest in fossils. A primary goal of NMNH Paleo is to ensure that each stakeholder group has access to fossil data at the appropriate level. As part of this goal, the Department is working to support the accountability needs of other stakeholders, such as federal land managers, by improving methods of sharing fossil data. The first phase of this work is defining the fossil data access and accountability needs for each stakeholder group. Much of this will be determined by the implementation of various regulations as well as agreements between land managers and repositories. The second phase is defining what kinds of data need to be shared to meet those needs. Georeferencing legacy collections is critical in identifying what specimens are important to what stakeholder. The third phase is building capacity and developing a cyberinfrastructure to mobilize data that were previously inaccessible or undiscoverable.

Muddy Creek, a deeply eroded tributary of the Bay, will soon be restored with a Regenerative Stormwater Conveyance (RSC) to reconnect the stream to the floodplain. The goal is to induce infiltration to remove suspended sediments, nitrogen and phosphorous from the stream water by diverting high flow over the floodplain. Flows of water, sediment and nutrients will be compared before and after the restoration to determine the effectiveness in restoring stream function. Before the restoration, groundwater quality and flow rate were measured along the restoration site's 450 m reach. The groundwater was determined to be anoxic, with dissolved oxygen ranging from 0 to about 1 mg/L, phosphate-P up to 46 mu g/L, and ammonium-N up to 450 mu g/L. Groundwater nitrate concentrations were below 11 mu g/L and iron concentrations exceeded 9 mg/L in some locations, suggesting denitrification and iron oxide reduction were occurring in the aquifer. Groundwater emerging along the restoration reach made up 15% of the stream flow exiting the reach, as determined on one date by dilution of bromide tracer added at the upstream end. Success of the RSC will be judged from decreases in nutrient concentration in stream water beyond the effect of mixture with emerging groundwater. If the RSC approach is successful, it could provide a guide to future stream restorations.

Although variations in the major element content of gahnite in different geologic environments are known, those of trace-elements are still unknown for several settings. The major- and trace-element composition of gahnite in Broken Hill-type (BHT) deposits was recently investigated to distinguish prospective BHT deposits from non-prospective BHT occurrences. Here we present the first in-situ trace-element compositions of gahnite from various types of LCT (lithium-cesium-tantalum enriched) granitic pegmatites (25) worldwide obtained by LA-ICP-MS and compare them, along with major- and minor- element contents, with those from BHT deposits (12) of the southern Curnamona Province, Australia, to identify compositional differences indicative of each environment. Major-element contents of gahnite in both environments partly overlap, but those in granitic pegmatites have higher Zn contents. In addition, gahnite in granitic pegmatites has higher Mn (1,300 - 8,800 ppm; avg. 3,850 ppm), Li (6 - 243 ppm; avg. 52 ppm), and Cu (8 - 68 ppm; avg. 25 ppm), and lower Mg (30-5,765 ppm; avg. 1,213 ppm), Fe (0.55 - 8.8 wt.% Fe; avg. 4.8 wt.%), Cr (1-11 ppm; avg. 3.5 ppm), Co (0-40 ppm; avg. 6 ppm), and Ni (1.8 - 18.7 ppm; avg. 6 ppm) contents than gahnite in BHT deposits. Gahnite with Mg 4,000 ppm, Li > 28 ppm, Cu > 40 ppm, Cr > 10 ppm, Co approximately 6,000 ppm, Fe > 8.8 wt.%, Cr > 11 ppm, Ni > 20 ppm, and Co > 40 ppm characterizes BHT deposits. A Cu-Co-Cr ternary diagram clearly separates gahnite from both settings. High Mg, Fe, Cr, Co, and Ni contents in gahnite from BHT deposits are consistent with a previously recognized genetic relationship with mafic magmatism. High Li and low Fe, Mg, Cr, Co, and Ni contents in gahnite from granitic pegmatites reflect the ultra-felsic composition of these rocks and extreme fractional crystallization. Combined major- and trace-element compositions of gahnite obtained from covered terranes can be used as chemical fingerprints to distinguish granitic pegmatites from BHT deposit sources.

Despite a long history of scientific investigation at the site beginning in the 1950s major questions remain concerning the factors that concentrated so many large vertebrate skeletons in a relatively small area, as well as the broader paleoenvironmental and depositional context and the paleoecology of Shonisaurus. In order to generate a rigorous framework to tackle these questions with testable hypotheses we present preliminary results from a two-year investigation of the site integrating multiple digitization approaches (LiDAR, photogrammetry, structured light, laser scanning) cross-referenced with conventional field techniques (e.g., in situ measurement, field mapping) and archival investigation. Work at the site is challenging because the quarry is preserved as a sheltered permanent public display in a remote location. Three-dimensional (3D) digitization provides a means to create digital models that can be studied, shared or even printed offsite. Initial photogrammetry incorporating approximately 1500 images produced a useful overview model for preliminary taphonomic assessment. However, processing revealed artifacts, soft spots and holes owing to site-specific conditions (e.g., faulting, limited contrast between matrix and fossils, uneven shadows and lighting) and the general challenges presented by digitizing a large uneven surface. High resolution (cm-scale) terrestrial-based LiDAR permits georeferencing and larger scale site context including imagery of the shelter and surrounding hillside. Structured light (Artec Eva and Spider) scanners provide enhanced detail for smaller features of interest. Follow-up work, including additional photogrammetry and laser (Surphaser) scanners, will systematically target weaknesses and improve the model. Finally, archival investigation of field notes, maps and photographs from past excavations, along with biostratigraphic and geochemical data provide additional avenues to illuminate the geology and paleobiology of this iconic vertebrate fossil locality.

Building on initiatives started for biological collections, GRSciColl expands this framework to encompass all scientific disciplines including earth and space sciences, anthropology, archaeology, biomedicine, and applied fields such as agriculture and technology. A subset of GRSciColl focuses on the U.S. federal scientific collections - this portal contains the same information as GRSciColl but includes only collections owned, managed, or overseen by a U.S. federal agency. The goals of these registries are to (1) provide a single source of synoptic information about the collections, their institutions, and staff; and (2) facilitate the assignment of identifiers for institutions and collections that are globally unique across all disciplines. Institutional records include categorization by governance (e.g., national, state or local governmental, private non-profit) and by scientific discipline (e.g., earth science, biomedical, agricultural). Collection-level metadata categorize the types of contained specimens/samples and modes of preservation. In selecting the level of granularity for these categories, designers sought a compromise that would capture enough information to be useful in searches and inquiries and would complement the detailed archives in specimen-level databases hosted by discipline-specific groups (e.g. SESAR) or the institutions themselves (e.g. KE EMu).

The supergroup also includes some oxides, hydroxides, vanadates, arsenates and one halide, but the most widespread members are the six common silicate species that belong to the garnet group (i.e., almandine, spessartine, pyrope, grossular, andradite, and uvarovite). Previously, Alvey et al. (2010, Appl. Opt. 49, C168) analyzed 157 samples described as garnets from 92 locations worldwide using laser-induced breakdown spectroscopy (LIBS) and demonstrated that LIBS has the potential to discern garnet geographic origin using the concept of 'geochemical fingerprinting'. In this study, an expanded suite of over 203 garnets was examined using electron microprobe microanalysis (EPMA) to correctly classify the samples on the basis of their major element composition and then ascertain the efficacy of LIBS for classification and provenance determination. The LIBS spectral data were processed using multivariate statistical pattern recognition methods (e.g., PCA, PLSDA) and the resulting classification models then used to successfully classify unknown garnet samples of a specific compositional type according to their geographic origin. Various preprocessing techniques (normalization, spectral outlier removal) were implemented to optimize the LIBS classification results. This study demonstrates that LIBS offers a good alternative for identification of unknown garnet samples based on their geographic provenance.

The Gakkel Ridge is the world's slowest spreading ridge, and exposes peridotites along its axis that record the activity of oxygen in the upper mantle. Our samples comprise relatively fertile lherzolites and harzburgites (Cr#=0.13-0.17, 3.1-8.3% modal cpx) as well as refractory harzburgites (Cr#=0.43-0.55, 0.2-1.0% modal cpx). Using spinel peridotite oxygen barometry, we calculated the oxygen fugacity (fO (sub 2) ) of a suite of 10 peridotites from the Gakkel Ridge in order to investigate how melt processes affect the oxygen budget of the Earth's interior. We show that the low-Cr# lherzolites and harzburgites range from -0.1 to +0.6 log units relative to the QFM buffer, consistent with the global abyssal peridotite array, whereas high-Cr# refractory harzburgites have low fO (sub 2) values, ranging from -0.7 to -2.7 log units below QFM, with the most refractory samples falling significantly lower than the global array. Because D'Errico et al. (submitted) interprets the refractory samples as recording ancient melt extraction, the low fO (sub 2) recorded by these samples may originate in the geologic past, perhaps even in a different tectonic setting. While LREE enrichment in the refractory harzburgites provides evidence for refertilization by an infiltrating melt that could have recently imprinted reducing conditions, we see no corresponding increase in TiO (sub 2) content in the spinels, which weakens this hypothesis. Further research on additional refractory harzburgites is needed to constrain whether the reduced nature of these samples is telling us something about the effect of extreme melt extraction on fO (sub 2) at ridges, or whether these samples record a unique history that obscures processes operating at ridges today.

In the Valley of the Gods area, sections 11 km apart were measured in the Early Permian Halgaito Formation, from the McKim Limestone to the overlying Cedar Mesa Formation, divided into two packages about 55 and 25 m thick. The lower package has lenticular channel bodies of very fine sandstone and siltstone with trough cross-beds, ripple cross-lamination (commonly climbing), plane beds, and mudstone lenses. Carbonate-pebble conglomerates, desiccation cracks and adhesion features are present. The channel bodies represent broad, shallow sandbed rivers with seasonal flow. Plant material includes impression remains of the conifer Walchia, stems of calamitaleans, tree ferns, and rarely lycopsids, and root traces. Diplichnites cuithensis trackways are present in one channel body, as well as other abundant vertical and horizontal burrow ichnofossils. Laminated, bioturbated sandstone and shale a few metres thick represent shallow lakes. Sheets of red, weakly stratified siltstone and very fine sandstone are identified as loess. In places, they form 4 m stacks incised by channel bodies with steep and overhanging margins. Elsewhere, loess lenses are present within channel bodies and lake deposits. The upper package has a high proportion of loess sheets up to 2 m thick, stacked into composite units and penetrated by deep root traces. They are intercalated with thin channel bodies and poorly developed paleosols. Even thin loess layers are traceable for several kilometres. Aeolian sandstone of the Cedar Mesa Formation abruptly overlie the package. The succession records progressive aridification from rivers and lakes with plant and animal fossils to stacked, rooted loess sheets below aeolian dunes. A key feature is the dynamic nature of the landscape, with interaction between rivers, lakes and eolian sediment as drainage adjusted to aeolian aggradation on floodplains and in channels. Vegetation played an important role in stabilizing the landscape after aeolian events.

Abundance, diversity and taphonomy for the Lower Permian Halgaito Formation of the Paradox Basin, Utah AN - 1784737205; 2016-037737 AB - During the Early Permian, the plains of western Pangea included eolian dunes and fine-grained sheets (loess), suggesting an arid landscape and minimal vegetation cover. To assess the importance of vegetation in the landscape, we examined the upper Halgaito Formation of earliest Permian age, widely exposed in the Valley of the Gods region of the Paradox Basin. Stem fragments and comminuted plant debris were discovered in only a few channel bodies, in basal plane-bedded sandstone and climbing ripples that indicate rapid accumulation of water-saturated sediment under seasonal flow conditions. Rare macrofossil foliage includes impression remains of the conifer Walchia, tree fern Pecopteris and sphenopsid Annularia. More common are impressions of stems of tree ferns and calamitaleans, and rarely lycopsids (Sigillaria). In contrast to the scarcity of above-ground material, regularly spaced large root traces are abundant. The root traces penetrate up to 3 m within the upper parts of channel bodies, are prominent in near-structureless to stratified beds of eolian fines and, where adequate clays were present, in soils with vertic features and locally with carbonate nodules. Exposed surfaces of sandstone show abundant stem bases with radiating, shallowly disposed roots and carbonate rhizoconcretions, as well as smaller root systems. Vegetation evidently grew at many times and in most places throughout the area, where roots penetrated deeply to access groundwater. The high ratio of root traces to preserved plant material implies a taphonomic megabias that may operate in most such seasonally dry settings. The Paradox Basin patterns suggest 1) that vegetation was prominent at times across these Early Permian landscapes, with a probable range of plant sizes, but 2) that the scarcity of shallow groundwater and standing-water bodies limited the preservation of plant litter to active stream deposits during times of widespread vegetation.

The bulk composition of the sandstone was analyzed using both instrumental neutron activation analysis (INAA) and prompt gamma activation analysis (PGAA). The results were consistent with the composition of a typical arkosic, micaceous sandstone from the Triassic Newark Supergroup formation. The mineral assemblage was characterized using hyperspectral X-ray microanalysis in the scanning electron microscope. The stone consists primarily of quartz, feldspars and mica. Portable XRF analysis found that the surface layer of rock varnish was significantly enriched in Mn compared to the underlying sandstone. This was confirmed by femtosecond laser ablation-inductively coupled plasma-mass spectrometry (fs LA-ICP-MS) with a Mn/Fe ratio in the rock varnish of 1.40-1.63 compared to the ratio of 0.01 to 0.02 in the bulk sandstone as determined by INAA. X-ray microanalysis analysis has not yet revealed any Mn-rich minerals such as ilmenite or titanite in the sandstone that could be the source of the Mn in the varnish layer. Therefore the preliminary conclusion is that the source of Mn is airborne particulate matter. Based on the differential attenuation of the Fe Ka and Kb peaks in the portable XRF spectra, it was possible to estimate the thickness of a hypothetical MnO (sub 2) layer at 4+ or -1 mu m, which implies an average growth rate of 26+ or -6.5 mu m/kiloyear over the lifetime of the Castle. Both the portable XRF and fs LA-ICP-MS found elevated Pb and Cl concentrations in the rock varnish. The former is presumably from automobile pollution and the latter, a combination of road de-icing salts and sea salt particles.

It is an arkosic, micaceous sandstone as indicated by micro-X-ray diffraction (XRD) analyses, which show that quartz, alkali feldspar, and muscovite predominate. Instrumental neutron activation analysis (INAA) measured about 5% Fe (sub 2) O (sub 3) , which accounts for the characteristic red color. Trace amounts of manganese (0.05% MnO (sub 2) ) may also affect the coloration. The formal name for Seneca sandstone is the Poolesville Member of the Manassas Formation. This occurs in the Culpepper Basin, which passes from Virginia into Maryland under the Potomac River. This formation is in turn a member of the Newark Supergroup, a series of Triassic sandstone basins that reach from North Carolina to Massachusetts. The Newark Basin in New Jersey, as well as quarries along the Connecticut River in Massachusetts, supplied much of the brownstone used in New York City buildings during the 19th century. The Seneca quarries were located in Maryland near where Seneca and Bull Run Creeks enter the Potomac River about 40 km northwest of the District. It has been quarried since 1774, but the opening of the C&O Canal as far as Seneca, MD, in 1831 made possible the operation of the quarries on a large-scale commercial basis. The most prominent example of its use was for the Smithsonian Castle's construction in 1847-1855. Its selection for this building involved one of the earliest applications of the sodium sulfate test for stone durability. The Castle's design, by James Renwick, Jr., established the Romanesque Revival architectural style, which was popular during the Victorian era. Seneca sandstone was used extensively in public and private buildings during this period, but fell out of fashion by its end. Quarrying had mostly ceased by 1900 as good-quality stone became scarce, and the quarries were completely abandoned after severe flooding in 1924. Remains of the quarry, including the ruins of a stonecutting mill, can be visited in Seneca Creek State Park in Potomac, Maryland.

We present eight categories of biotic interactions involving seven insect orders interacting with coexisting plants, other insects and vertebrates. First, the long-proboscid pollination mode is a pollinator mutualism by three families of Mecoptera that evolved convergent siphonate mouthparts for imbibition of pollination drops from tubules or channels in gymnosperm ovulate organs. Second, mimesis, or camouflage, was present in two lacewing taxa that imitated co-occurring pinnate gymnosperm pinnules. Similarly, a scorpionfly mimicked an entire co-occurring ginkgo leaf, presumably providing protection to plant model and insect mimic. Third, considerable insect damage is recorded on a variety of plants involving galls by Coleoptera and stylate punctures and margin feeding, probably by Hemiptera and Orthoptera, respectively, among others, on vascular-plant tissues. Fourth, integumental blood feeding was established by ectoparasites such as a basal lineage of fleas (Siphonaptera) that possessed long stylets consisting of robust, outwardly directed, serrated stylets, and bugs (Hemiptera) involved in piercing thick vertebrate integument and imbibing host blood and possibly lymph. Fifth, parasitoid larvae, especially highly diverse apocritan wasps such as Ephialtitidae and Pelecinidae (Hymenoptera) consumed the integument and body cavities of other host arthropods. Sixth, predatory feeding by diverse insects, such as hangingflies (Mecoptera) and mantispids (Neuroptera) were equipped with prey-neutralizing devices. Seventh, two genera of Mecoptera with exaggerated male organs, likely representing the earliest example of long-term male-male competition in insects. Eighth, reproduction was highlighted by a pair of copulating froghoppers (Hemiptera), hitherto the earliest record of copulating insects in flagrante delicto. These eight, intricate, mid-Mesozoic associations provide an expanded understanding of the ecologic role and necessary evolutionary developments that insects had in mid-Mesozoic ecosystems.

Shortly after the arrival of humans, about 80% of these megaherbivores were extinct, including all taxa over 600 kg. Studies of this event have generally focused on the causes of the terminal Pleistocene extinction rather than the ecosystem consequences of the loss of tens of millions of megaherbivores in North America. Here, we examine the response of a small gazing rodent, Sigmodon hispidus (cotton rat), to the extinction at a single location in the Great Plains of Texas. At Hall's Cave, the megafauna extinction led to the catastrophic loss of 80% (12 of 15 species) of large-bodied herbivores and 20% (3 of 15 species) of apex predators. Using 16 tightly constrained temporal windows spanning the full glacial to the modern, and employing measurements of the lower M1, we examine population-level changes in body size of cotton rats before and after the extinction and during times of shifting climate. We find a dramatic and sustained increase in the mean body size of the population just after the extinction. This occurs despite a warming climate, which according to Bergmann's rule would select for smaller, not larger body size. Moreover, the change in population body size is accompanied by a time transgressive shift in isotopic dietary niche and a greater overall isotopic dietary space. Our results suggest that cotton rats invaded new ecological niche space after the extinction of megaherbivores, and indicate that a combination of behavioral, physiological and morphological responses are likely for modern species in the wake of trophic downgrading.

But any general approach to macroevolution must encompass the most generative evolutionary event of the Phanerozoic. Among the issues that need to be resolved are the factors that triggered the events of this interval: Was the Cambrian radiation an evolutionary response to a late Ediacaran mass extinction? Do organisms actively construct their environments and the niches that they inhabit? Or, as most evolutionary theory assumes, do organisms more passively adapt to the ecological opportunities presented by the environment? The diversification of animals during the Ediacaran and early Cambrian Periods highlights the ongoing debates among evolutionary biologists about physical versus biological drivers of evolutionary novelty (the origin of new individuated phenotypic characters) and innovation (the ecological and eventual evolutionary success of evolutionary novelties). The long-prevailing view has been that the Ediacaran-Cambrian Radiation (ECR) was driven by physically mediated changes in the environment, particularly redox levels, with animals responding to these changes. Alternatively, some recent authors have advanced the view that the niche constructing and ecosystem engineering activities of organisms actively modified the environment sufficiently to drive the diversification. Evolutionary diversifications driven, at least in part, by positive feedback expand the range of models of macroevolution beyond the ritual invocation of adaptive radiations.

We examined plant-insect interactions to understand how insect herbivores occupied particular feeding niches during the late Paleozoic. We documented patterns of insect herbivory at the early Permian Sanzenbacher Locality in north-central Texas, probably dating to the Wolfcampian Stage. The Sanzenbacher deposit consists of ca. 300 specimens of vascular plants embedded in a mudstone matrix associated with a fluvial depositional environment. This flora is dominated, in decreasing order of abundance, by the genera Pecopteris, Autunia, Neurodontopteris, Cordaites, Mariopteris and Rhachiphyllum. By (i) recording the frequency of insect-mediated damage, (ii) establishing the particular spectrum of damage types (DTs) present, and (iii) documenting the percent of herbivorized foliage by area for each taxon, indices were calculated to express the DT frequency and richness for each host species and for the entire bulk flora. These three modes of estimating fossil herbivory also allow determination of the proportion of specialized vs. generalized herbivory and which plant host taxon was the most consumed. The sphenopsid genus, Sphenophyllum, and the medullosan genus, Neurodontopteris, were the most highly damaged of the major morphotypes based on sufficiently adequate sample sizes. However, Annularia had the greatest herbivory but sample sizes were too low for acceptance. The most common insect damage, in decreasing abundance, was hole feeding, margin feeding, piercing and sucking (mostly scale insect marks), and surface feeding. The elevated presence of circular to ovoidal scale marks, likely attributable to coccoid Hemiptera, was notable. Herbivory for the bulk flora was 2.65 %, somewhat less than a third of most modern values. These data, when analyzed multivariately with several other floras from the early Permian of north-central Texas, will provide an assessment of herbivory in a mosaic of environments during an approximate 20 million time interval.

These studies must use indirect proxies for the origination and extinction of lineages but the fossil record may allow for more direct testing, provided that the focal taxon has sexually dimorphic hard parts. Cytheroidean ostracodes are one such taxon: in extant members of this order, male valves are elongate relative to those of females, a shape difference presumed to relate to the large copulatory apparatus of males. Here we report the initial results of a investigation using the fossil record of Late Cretaceous ostracodes from the US Gulf Coastal Plain, with a focus on (1) developing a protocol for reliably measuring dimorphism; (2) documenting the patterns of dimorphism in the focal ostracode fauna; and (3) analyzing the stability of sexual dimorphism as a species-level trait. We digitized the valve outlines of adult specimens and computed area as a measure of body size. Each outline was approximated as an ellipse, and the ratio of the major to minor axes was used as a measure of valve elongation. Likelihood-based mixture models were used to identify male and female clusters in size-shape space and differences between the inferred sexes were used as estimates of the magnitudes of size and shape dimorphism. In nearly all samples with adequate sample size, we find evidence for two clusters consistent with sex differences. Thus far, we have measured nearly 5,000 ostracodes to produce 109 population-level estimates of dimorphism for 77 species and 33 genera. Populations vary greatly in the strength of size and shape dimorphism. Males are more elongate than females by as little as 2% or as much as 20%. Males are usually the larger sex but can range from 15% smaller to 30% larger than females. Magnitudes of size and shape dimorphism are not correlated, and neither is related to body size, suggesting that dimorphism differences are not simply a manifestation of selection for body size. Estimates of dimorphism are quite stable within species, mostly similar among congeners, but not very conserved at the family level. Thus, although they are subject to evolutionary divergence, the sexual selection regimes that underpin sex differences can be stable enough to be treated as species-level traits for macroevolutionary analysis.

Average coral cover at 90 reef locations from Bermuda to South America declined by half since 1970 while macroalgae increased 3-fold. Most of the decline occurred before the first outbreaks of coral bleaching so that climate change was not responsible. Moreover, coral cover has been more stable and macroalgae rare at locations protected from overfishing and pollution, suggesting that local human impacts have been the major drivers of coral decline up to now. White Band Disease virtually eliminated acroporid corals from most reefs in the 1980s while other corals have been more resilient to disease. The causes of disease outbreaks are unknown, but some may have been introduced through the Panama Canal. Increased pathogen diversity and abundance due to declining water quality may also be important factors. Extreme heating events and coral bleaching caused extensive coral mortality on overfished reefs where abundant macroalgae increase the likelihood of coral disease and inhibit coral recruitment and growth. Extreme heating events have had little impact on protected reefs. Two outstanding questions for the long-term future of Caribbean reefs are (1) the extent to which strong local protections from overfishing and pollution can continue to confer coral resilience to rising temperatures and declining pH, and (2) and the possibility of coral adaptation to these harmful consequences of climate change. Reef composition will almost certainly change with the likely loss of fast growing branching corals and increased dominance of more physiologically resilient massive species. Nevertheless, much could be done in the meantime to reverse the decline of Caribbean reefs by effective regulation of overfishing and coastal development.

In the past few decades, developmental evolutionary biology has made great headway in elucidating both the components and the organization of the gene regulatory networks that build morphology. We now recognize that developmental networks are highly conserved, and are often tightly associated with particular features; conversely, different types of generic network structure can specify similar morphological patterns and character arrangements. These developmental patterns can serve as a basis for studying living and fossil morphologies, and for organizing morphological data for phylogenetic analysis. I describe how the developmental underpinnings of morphology may be used to reorganize discrete morphological character data, focusing on how network structure translates into a separation of character identity from character states. This reorganization recognizes the biological distinctiveness of both "traditional" characters, such as appendages, and of patterning mechanisms which may be re-deployed across multiple body regions, and extends homology beyond a position-specific designation. Because the complex wiring of developmental networks can impose lineage-specific constraints upon the pattern and rate of morphological character evolution, this approach provides a first step in forming a probabilistic model for the evolution of morphology, as well as future application to phylogenetic methods utilizing morphological characters.

Slow rates of evolution in mitochondrial genes, limited numbers of informative morphological characters, plasticity of skeletal morphology in response to environmental conditions, and in some cases hybridization have all slowed progress. Nevertheless, progress has been made, particularly when multiple approaches have been brought to bear. Our understanding of evolutionary relationships is very different today than it was twenty years ago, and this has necessitated wholesale taxonomic revisions, with many still ongoing. Solving the coral "species problem" has to be done group by group, a time-consuming process, and many problem areas remain. High-throughput sequencing approaches are increasingly being used on corals, but typically not for systematic questions. More genetic data will undoubtedly help, but is unlikely to be a magic bullet, especially considering the extensive fossil record that corals possess. Fortunately, sophisticated morphological analyses often yield results that are concordant with molecular results, offering hope for those wishing to reconstruct the evolutionary history of corals with no close living relatives.

However, some conceptual difficulties arise when two trees have different numbers of hypothesized observed ancestors and/or polytomies, and thus have different numbers of freely varying branches. Reducing branches reduces the likelihoods of trees given morphology by reducing possible evolutionary pathways. Conversely, reducing branches (particularly by hypothesizing observed ancestors) increases the likelihoods of trees given stratigraphy by reducing possible sampling gaps. An alternative is to estimate prior probabilities on numbers of gaps in a tree. Although the single most probable gap for any one lineage is no gaps, the expected number of gaps for N lineages with preservation rate R approximates a gamma distribution with shape=N and scale=1/R. For any one lineage, this includes unsampled ancestors, which obviates a need to accommodate speciation rates. A small correction is needed to take into account expected "shared" gaps due to shared unsampled common ancestors. Because we can empirically estimate sampling intensities and opportunities, one can take into account variable sampling over time and among taxa. In the former case, we can even allow for some completely unsampled regions or environments; in the latter case, we can use among-lineage variation in sampling rates (typically following a lognormal distribution) to model a hyperprior distribution for R. Finally, because we can estimate probabilities of lineages being in different geographic regions or environments, the prior probabilities can vary on different trees that allow for easier (or more difficult) scenarios for "hiding" lineages. In addition to obviating the issue of different model complexities for the same hypothesis, another intuitive benefit of this approach is that some number of gaps will almost always be more probable than no stratigraphic gaps, even though the most likely scenario for any one lineage (and thus the whole clade) is no gaps. This in turn can increase the posterior probability of deeper divergences that otherwise are less likely.

Past. 10, 1779-1801 (2014), the authors employ the HITRAN2012 spectroscopic database to evaluate the radiative forcing of 28 Archean gases. As part of the evaluation of the status of the spectroscopy of these gases in the selected spectral region (50-1800 cm (super -1) ), the cross sections generated from the HITRAN line-by-line parameters were compared with those of the PNNL database of experimental cross sections recorded at moderate resolution. The authors claimed that for NO (sub 2) , HNO (sub 3) , H (sub 2) CO, H (sub 2) O (sub 2) , HCOOH, C (sub 2) H (sub 4) , CH (sub 3) OH and CH (sub 3) Br there exist large or sometimes severe disagreements between the databases. In this work we show that for only three of these eight gases a modest discrepancy does exist between the two databases and we explain the origin of the differences. For the other five gases, the disagreements are not nearly at the scale suggested by the authors, while we explain some of the differences that do exist. In summary, the agreement between the HITRAN and PNNL databases is very good, although not perfect. Typically differences do not exceed 10 %, provided that HITRAN data exist for the bands/wavelengths of interest. It appears that a molecule-dependent combination of errors has affected the conclusions of the authors. In at least one case it appears that they did not take the correct file from PNNL (N (sub 2) O (sub 4) (dimer)+ NO (sub 2) was used in place of the monomer). Finally, cross sections of HO (sub 2) from HITRAN (which do not have a PNNL counterpart) were not calculated correctly in BG, while in the case of HF misleading discussion was presented there based on the confusion by foreign or noise features in the experimental PNNL spectra.

However, studies of the influence of sexual selection on extinct organisms have been limited by a focus on mineralized hard parts of organisms, which are more readily preserved in the fossil record. Ostracodes offer an excellent system to explore sexual dimorphism as an indicator of sexual selection in both soft and hard parts. Male valves in cytheroidean ostracodes are more elongate than those of females, a shape difference hypothesized to result from a need to accommodate the very large male copulatory apparatus, which can account for up to 1/3 of body volume and may relate to the strength of sperm competition among males. Here, we examine the correlations between hard and soft parts in this group in order to test, in extant taxa, how male investment in primary sexual traits (soft parts) correlates with sexual dimorphism in ostracode valves (hard parts). We chose to study the genus Cyprideis because the group is characterized by strong and variable valve dimorphism. Specimens were collected in the field (C. salebrosa, USA; C. torosa, UK) or obtained from collections of the National Museum of Natural History, Washington DC (C. mexicana). We digitized valve outlines to obtain measures of size (valve area) and shape (length to width ratio), and obtained several linear distances of the hemipenis, a primary sexual trait. Linear dimensions from four limbs were also measured as indicators of overall (soft-part) body size and allometry of the sexual structures was tested. We verified that absolute size of soft parts is correlated with absolute valve size, suggesting that body size measured from hard parts is a good proxy for soft-part size, and therefore probably body mass as well. We also found that the absolute size of the hemipenis also correlated positively to valve area. Conversely, hemipenis size relative to other soft parts was not strongly related to valve elongation. Thus, results thus far indicate that sexual size dimorphism, perhaps as much or more so than shape dimorphism, may be an indicator of sexual selection acting on male reproductive investment. These findings can help to interpret the evolutionary significance of valve dimorphism as observed in the fossil record.

Subsequent nitrate delivery from streams to estuaries such as Chesapeake Bay is an important driver of eutrophication, causing harmful algal blooms, depletion of dissolved oxygen, and demise of submerged aquatic vegetation. However, some of the nitrate may be removed from groundwater by microbial reduction to N (sub 2) . We investigated groundwater nitrate delivery to channelized streams draining a 4.8 km (super 2) watershed where agriculture was the dominant N source. We sampled emerging groundwater with piezometers drawing from 0.5 m depth mid-channel in the stream bed, in essence using drainage ditches as a window into the aquifer. We used membrane inlet mass spectrometry to measure N (sub 2) , oxygen, and argon concentrations in groundwater and estimated biogenic N (sub 2) by comparisons to argon concentration. Concentrations of nitrate and biogenic N (sub 2) in emerging groundwater varied markedly along the stream channel: nitrate ranged from near 0 to 1.5 mM and biogenic N (sub 2) ranged from 0.05 to 0.59 mM. Large spatial differences often occurred over tens of meters of channel length and much of the nitrate delivery was focused in short sections of the stream with no clear relation to changes in the adjacent land cover. Biogenic N (sub 2) increased as nitrate decreased but by less than equimolar amounts, suggesting that groundwater flow paths to the stream differed in initial nitrate concentration as well as in biogenic N (sub 2) production. Concentrations of dissolved iron, oxygen, nitrate, and biogenic N (sub 2) followed expected oxidation-reduction relationships. As oxygen declined, nitrate declined and biogenic N (sub 2) increased. Iron concentrations generally remained below 0.01 mM but ranged up to 0.6 mM when nitrate dropped below 0.01 mM. Sulfate concentrations increased with decreases in nitrate, suggesting that nitrate reduction might be coupled to sulfide oxidation in the aquifer. Thus the capacity for nitrate reduction may partly depend on the pool of sulfide minerals in the aquifer.

The SAP Flora is a mud-filled channel deposit and represents the youngest plant assemblage in the Blaine Formation (Guadalupian Epoch, 272-260 Ma). SAP consists of 15 recognized plant species, which has produced a rank abundance curve consisting of one very common strap-shaped, broadleaved conifer species, four less common conifers (including a parallel-veined large form) and the horsetail Sphenopyllum in intermediate abundance, and 12 rare conifer and gigantopterid species. Of the 925 leaves evaluated for insect damage, only 3.6% displayed evidence of insect herbivory or oviposition. This herbivory was partitioned into five insect functional feeding groups on SAP leaves: margin feeding, hole feeding, piercing and sucking, skeletonization and galling. Two instances of oviposition also are present in SAP leaves. The heaviest concentration of herbivory occurred on the large and small gigantopterid species where 35.7% and 20% of the leaves, respectively, exhibited at least one type of insect damage. Other forms of herbivory occurred on the strap-shaped conifer and large, parallel veined conifer, the latter of which had ten times more damage than the former. The low frequency of herbivory is almost certainly a result of the low plant diversity. A general tendency toward aridity during the middle Permian likely caused a shift in plant composition, which in turn reduced levels of insect herbivory. The lack of specialized insect herbivory also supports a turnover pattern in regional floras. The difference in damage frequency between the two species of broadleaved conifer may be due to differences in quantitative and/or qualitative secondary defense chemicals, typically enhanced in arid-adapted plants. Another possibility is co-association of the large, broadleaved conifer with a particular herbivore component community. The coarse-grained sedimentary rock of the SAP Flora also could have contributed to the low occurrence of insect herbivory.

The fossil record of plants, insects, and their associations of herbivory, pollination and mimicry provide valuable data for understanding patterns involving ecological and evolutionary associational processes between two most diverse groups on land. In our study of the Williamson Drive Flora of north-central Texas, we use both qualitative and quantitative analyses for: 1), examining the spectrum (diversity) of herbivory; and 2), estimating the amount of insect-mediated damage based on the frequency of damage type (or DT) occurrences and the herbivorized leaf area as a fraction of total leaf area. The Williamson Drive Flora occurs within the Markley Formation, was deposited in a fluvially dominated coastal-plain on the eastern shelf of the Midland Basin, and is composed of uppermost Pennsylvanian and lowermost Permian strata. This moderately diverse flora is dated probably to the Asselian Stage. Approximately 3,200 specimens have been evaluated and can be grouped into 48 plant taxa. The dominant taxa (in descending order) are: Macroneuropteris scheuchzeri, Calamites sp., Sphenophyllum sp., Annularia carinata, Pseudomariopteris cordato-ovata, and Lilpopia raciborskii. More than 620 herbivorized specimens were found and their DT occurrences were divided into seven functional feeding groups: hole feeding, margin feeding, surface feeding, oviposition, piercing and sucking, galling and wood boring. Of the 47 recorded DTs, four were new. Recent case studies have examined insect herbivory from the early Permian of Texas. Compared to the three other localities of this regional stratigraphic sequence from north-central Texas - Taint, Coprolite Bone Bed and Colwell Creek Pond - the Williamson Drive flora is the earliest and possesses a coal-swamp cast. This environment includes elevated abundance and diversity of plant taxa, inclusion of taxa such as Macroneuropteris and Calamites, representation by a high specimen numbers that often are leaf mats, and a display of specialized patterns of herbivory. Further analyses will explore additional patterns of herbivory, including possible insect culprits.

This request for accessible federally funded scientific data has led to an increase in efforts by many organizations, including the Smithsonian National Museum of Natural History (NMNH) Department of Paleobiology, to look towards new methods for compliance with this directive and for achieving our own goals of providing discoverable information to stakeholders. As a repository for paleontological specimens, a key focus for the NMNH Department of Paleobiology has been the development of a comprehensive understanding of the scope and state of fossils collected on public lands. This understanding requires collections to be discoverable. Discoverability cannot be achieved without first collaborating between organizations in order to work towards interoperable data that can be shared and used to enhance one another's collections. We are working closely with the USGS to formulate a method for discoverability of USGS paleontological collections that follows this exact mindset. In the NMNH Department of Paleobiology we manage data that is specimen based. At the USGS the paleontological data is organized by unique localities. These two different datasets have a high potential for overlap. By reconciling the different types of data from the collections cared for by both organizations we are able to build stronger records for fossils housed in Washington, D.C. and in Denver, CO with the ultimate goal of a comprehensive data set that can easily be shared and utilized for scientific research. The methods presented here were developed through collaborative workshops and data sharing and are being used to begin this process. We hope to continue development of these workflows in order to expand our collaborative efforts to other organizations entrusted with the care of fossils from public lands.

Archeological sites in the Olorgesailie basin show significant innovations in tool use technologies. Core from Olorgesailie/Koora region has been subject to initial analyses, including X-Ray Fluorescence (XRF) core scanning. In this study we focus on a laminated section of core between 117 and 120 meters below surface that appears to be deposited in a fresh deep-water lake. Characterization of the approximately 1 m laminations in this 3-meter section, and understanding their link to the regional environment, will aid in unraveling the story of sediment deposition at this location and sub-millennial climate reconstruction. XRF profiles of elemental concentrations across the laminated section of the core reveal cyclic environmental variability at several scales. For example, high Si:K and Ca contents may be interpreted as indicators of diatom productivity and autochthonous carbonate precipitation in the lake, respectively. Microfacies analyses of thin sections characterize compositions of dark and light laminae and aid in assessing the relationship between elemental content, minerals, and lacustrine processes.

Several publicly released DTMs of Martian dunes are available from the HiRISE web site, but we have also produced two DTMs of small (low-relief) Martian sand dunes using SOftCopy Exploitation Tool SET (SOCET SET) software at the Astrogeology Branch of the U.S. Geological Survey at Flagstaff, Arizona. Automated feature matching is often difficult on the relatively featureless Martian dunes, but through close attention to a favorable illumination angle and to minimizing the time elapsed between the stereo images, we obtained excellent DTM data where the ripples could provide control points between the stereo images. The DTM data supported a quantitative assessment of the magnitude of the possible deflection of ripple orientation (with respect to the formative wind direction) when a ripple is formed on the sloping surface of a sand dune (Howard, 1987); we conclude that ripple deflection on Martian dunes is minimal (<17 degrees ) for small dunes (surface slopes <10 degrees ) that lack a substantial slip face. Ripple orientation can therefore be correlated to the direction of the formative surface wind flow over shallow-sloped sand dunes, so that mapped ripple orientations can provide constraints on the most recent wind flow across Martian sand dunes. The DTMs have also been used in freeware (Wind Ninja) to investigate how dune shape may influence the local wind flow over the dunes, with the result that low-relief dunes do not appear to alter significantly the expected flow paths of the surface winds. However, dunes possessing slip faces may have both significant deflection of ripple orientation and altered wind surface flow near the slip face; ripple orientation data for such dunes should only be used well removed from regions where slip faces are present. It is remarkable that HiRISE images, along with the DTMs derived from stereo pairs, allow the documentation of wind flow patterns for individual sand dunes on the surface of another planet.

These reaction rinds exhibit complex chemical compositions some of which are the product of fluid-assisted metasomatic alteration. Bulk-rock lithium isotopic analysis was performed on samples collected along traverse profiles across the contacts between mafic blocks and their reaction rinds and in some cases into the matrix from different metamorphic grades, including amphibolite, lawsonite-blueschist, and lawsonite-albite facies in order to determine the role played by fluid-mediated processes in the Catalina Schist. Amphibolite facies traverses display gradational variations in Li concentrations and isotopic composition across these traverses with both Li concentrations and isotopic compositions elevated in the rinds compared to the block cores. There is a systematic variation in both Li concentration and isotopic composition moving into the blocks over distances of 5-10 cm. Lower-grade traverses exhibit sharp contrasts between block rind and matrix. Variations were limited to shorter distances of <4 cm. One-dimensional simple diffusion and advection-diffusion models were fit to the profiles that indicate that in some cases advection of fluids is required along with diffusion in order to best explain the observed variations.

Outcrops in the Kenyan and Ethiopian rift valleys document repeated occurrences of freshwater lake systems and subarial landscapes over the past 4 million years in regions that are now primarily seasonally dry savanna. Drill cores potentially overcome the limited time resolution of outcrop records and allow characterization of paleoclimate with sufficient precision to examine the role of climate in hominin evolution. In the Olorgesailie Drilling Project, two drill cores were recovered in 2012 in the Olorgesailie/Koora region of southern Kenya. Alternations of lacustrine mud, tephras, paleosols and fluvial deposits accumulated as the drilled area repeatedly flooded and dried. Attempting to resolve continuous records of past environmental conditions at high resolution, we used the ITRAX XRF core scanner to characterize elemental variability of the sedimentary sequences. Careful data evaluation helped to disentangle primary and secondary signals and to identify unconformities. XRF data from the two drill sites (separated by approximately 900 m) were compared using lithostratigraphic correlation. Based on detailed lithostratigraphy, which includes smear-slide microscopic analyses and X-radiographic images, we identified sequences corresponding to event deposits and paleosols and developed an event-corrected, adjusted depth scale for the continuous lacustrine sequences, allowing us to create meaningful timeseries from proxy records. Our approach shows that, even within a highly variable lithostratigraphic context, robust and informative paleoclimate timeseries can be established by consistently implementing lithostratigraphic frameworks. In the approximately 1-Ma Olorgesailie drill core, timeseries of Si/K and Ca intensities, reflecting diatom productivity and calcium carbonate preservation, respectively, fluctuate on orbital as well as millennial timescales.

A consequence is the inoculation of the subsurface with surficial microorganisms, many of which could take advantage of the nutrients and carbon released during HF. Current practice is to control microbial growth by adding biocide to HF fluids. However, biocide is a significant cost and has important consequences for health, safety, and the environment. Here, we assess the effectiveness of the biocide tributyltetradecyl phosphonium chloride (TTPC) on the Eagle Ford Shale (EF) in Central Texas. Temperatures in the EF are >160 degrees C downhole, with conditions that cannot support viable microorganisms. However at lower temperatures, such as along the wellbore, viable microbial communities may be supported. Freshwater used in HF fluids as well as produced water were collected from a well site and characterized for their solution chemistry and microbial community. Field samples were also cultured in the laboratory in representative subsurface conditions at 128 degrees C and 60 degrees C, with and without TTPC. Cultures were assessed for viable cells, community composition, and geochemistry. At temperatures below 128 degrees C, cells are viable despite TTPC treatment though TTPC killed a significant number of the cells. After a two-week incubation with TTPC, nearly 50% of the total cells in cultures were still viable. Microbial diversity in TTPC-treated cultures was much lower than controls and likely contain a community of biocide-resistant organisms mostly represented by the classes Alphaproteobacteria, Actinobacteria, Gammaproteobacteria, and Cytophagia. There is little knowledge about how these organisms may impact production. In contrast, environmental PW samples contained a diverse microbial community despite TTPC treatment, and these organisms may be implicated in bioclogging, enhanced oil recovery, and corrosion such as Crenothrix, Microbacterium, and Thiobacillus. Our studies suggest that that TTPC will not completely sterilize the subsurface microbial community and that further characterization of biocide is necessary to determine if it is truly useful in HF operations.

The ITC preserves abundant vertebrate fossils and trackway surfaces, with two hominin taxa represented by body fossils and at least one hominin (probably Homo erectus) recorded in multiple footprint levels. Fluvial and lake margin deposits, including three widespread volcaniclastic units, alternate with paleosols in the ITC and indicate multiple cycles of deposition and subaerial exposure within the 20 kyr time interval. Vertebrates are preserved in bedded fluvial, deltaic, and lake margin sediments and less commonly in the paleosols. The ITC is an unusually rich source of fossil primates, diverse bovids, suids, and other ungulates. Systematic surface fossil surveys in ITC exposures indicate spatial differences in faunal composition across small distances ( approximately 5 km), with more aquatic vertebrates toward the west and greater diversity of terrestrial mammals toward the east. There is an upward trend through the ITC in Area 1A from more aquatic reptiles and fish to increased terrestrial components. Stable isotopes in ITC paleosol carbonate indicate dominant C4 (grass) with some C3 (bush, trees) vegetation. delta 13C analyses of tooth enamel from a wide range of mammalian herbivores show diets dominated by C4 vegetation, with relatively few C3 taxa. The combined faunal and stable isotope evidence from the ITC supports reconstruction of the habitat as grassland with areas of woodland and bush. The preserved trackways can be attributed to numerous mammals as well as crocodile and large birds that indicate the proximity of a large body of water. This is consistent with the sedimentology of the trackway surfaces, which formed near a relatively stable base level likely associated with a lake. Okote Mb. lacustrine deposits 50 km to the south provide additional evidence for an extensive lake between approximately 1.6 and 1.4 Ma in the northern Turkana Basin. The presence of this lake and the short-term transgression and regression cycles in the ITC represent two different scales of tectonic and/or climatic controls on deposition that interacted to form the Okote Mb. and preserve its rich paleontological record.

Numerous compilations of raw data suggest that marine metazoans diversified dramatically during the late Mesozoic and Cenozoic, with genus richness rising to about 2-4 times Paleozoic levels. However, bias-corrected analyses have indicated much less Cenozoic diversification, with most published curves showing leveling off or decreasing diversity in the Neogene, and these analyses are cited as evidence that biases strongly conceal underlying biological patterns in the global fossil record. We applied the SQS method to the Paleobiology Database (PBDB, paleobiodb.org) to re-examine these biases. Variation in data quantity did affect observed diversity, as in any study of taxonomic richness. However, taphonomic heterogeneity had only minor effects on the diversity curve once overall sampling intensity was standardized, indicating that preservation affects observed global diversity primarily through its effects on sample size. After correcting for biases, genus richness still increased substantially and continuously from the Jurassic to the Neogene. In the Cenozoic, observed richness rose to twice the Paleozoic average, which is within the range of outcomes seen in analyses of raw data, suggesting that the global marine fossil record does preserve first-order signals of diversity history. Previous standardized analyses did not capture this diversification in full because they were based on incomplete data that excluded some marine metazoans. Further improvements to the curve are expected as more data are added to the PBDB (particularly from undersampled clades and geographic regions) and as existing data are vetted, but consilience among methods suggests that the first-order signal of long-term diversification is robust. The Mesozoic-Cenozoic Radiation is one of the key features of marine animal diversity history-not since the early Paleozoic had diversity changed substantially and permanently.

The 1959 scoria contain abundant olivine + or - chromian spinel in highly vesicular brown glass. In 8 samples from phases 1-2 of the eruption, euhedral olivine phenocrysts (> or =1mm in length, and which appear to be in textural equilibrium with the enclosing glass), have rim compositions that vary from 88.2 to 86.0 mol % forsterite (Fo) within a thin section (and hence at constant major-element melt composition). Compositions of microphenocrystic and groundmass olivine in the same samples range from 88.0 to 82.0 mol %Fo, again within thin sections. These ranges do not track the large shifts in melt composition that occur with time in phases 1-2. By contrast, in the latest scoria of the eruption (from phases 10-16), the compositional range of phenocryst rims and groundmass olivines alike is only 85.5 to 84.0 mol %Fo. This narrower range, plus the overlap in ranges for large and small olivines, suggests that the exchange of Fe (super +2) and Mg between olivine and melt in the later samples was approaching chemical equilibrium. Eight 1959 scoria samples (five from phase 1, and one each from phases 3,10, and 15) were investigated by mu -XANES to determine directly the in situ Fe (super +3) /total iron for glasses next to selected olivines. This was done to test the hypothesis that the observed variable Fo contents might reflect variation in ferric iron in the melt, as variation in glass MgO and total FeO is minor within each sample. Fe (super +3) /total iron varies from 0.185 to 0.124 in various scoria glasses, with higher values in locally oxidized glass edges; this range explains some but not all of the variation in Fo content. The remaining variation in olivine compositions appears to result from mixing of thermally disparate magmas, which were erupted and quenched before internal equilibrium was achieved. Data for 24 olivine-melt pairs in the well-equilibrated late samples include 7 pairs of phenocryst rims + glass, one melt inclusion and 16 groundmass olivines + glass. Using the mu XANES data to correct for Fe (super +3) , the resulting values are KD = 0.28+ or -0.03 for the exchange of Fe (super +2) and Mg between olivine and melt, somewhat displaced from the widely accepted value of 0.30+ or -0.03 of Roeder and Emslie (1970).

Most biogenic Mn(IV/III) (hydr)oxides are highly reactive materials that can exert a large effect on trace metal concentrations via redox, adsorption, and coprecipitation processes. Mn(II)-oxidizing bacteria and fungi may promote the precipitation of Mn oxides in many natural and metal-polluted systems, such as coal mine drainage remediation sites. Laboratory-based studies of microbiological systems have often used biologically inert Good's Buffers (e.g., HEPES, MOPS, MES, etc.) to control for solution pH. However, a recent study of abiotic Mn oxides indicates that Good's Buffers may reduce structural Mn, thereby altering Mn oxide structures. Furthermore, the pH of natural systems are commonly controlled by carbonate buffers (not Good's Buffers), and Mn oxide formation can be altered by solution chemistry. Using a combination of X-ray diffraction, Fourier-transform infrared spectroscopy, and extended X-ray absorption fine structure spectroscopy, we are investigating the structures of Mn oxides produced during Mn oxidation by four Mn(II)-oxidizing Ascomycete fungi species in a buffer-free flow-through system and in closed- and flow through-systems buffered by HEPES or carbonate. We find that the buffer type affects fungal growth behaviors as well as Mn oxide production, with specific effects distinct for each species. For example in a calcium carbonate buffer, Stagonospora sp. SRC1lsM3a grows and oxidizes Mn(II) faster than in HEPES buffer which has traditionally been used by most studies of bacteriogenic and mycogenic Mn oxide formation. In addition, the effect of rehydration, to mimic wet and dry cycles, will be discussed. These results highlight the importance of in situ research under conditions that closely mimic natural systems to better constrain our understanding of the impact and fate of contaminants and nutrients in the environment.

Chrysotile, an asbestiform mineral used for industrial purposes, is common in serpentine-bearing rock formations and soils. Weathering of chrysotile can potentially promote CO (sub 2) sequestration via mineral carbonation. In contrast, this process can also result in the release of asbestiform fibers which represent a major respiratory hazard. One proposed asbestos remediation method is bioleaching by fungi that break down asbestiform serpentine minerals in the process of extracting iron as a micronutrient. Currently, however, the mechanisms, mineral alteration products, and geochemical impacts of fungi-induced weathering of chrysotile remains unclear. This study uses batch culture experiments to (1) determine if Talaromyces sp., a fungal strain isolated from serpentine soils in China (Li, Z., et al., 2015), is capable of breaking down the structure of chrysotile in vitro, (2) compare the bioleaching effect of Talaromyces sp. on chrysotile when bioavailable iron is present or absent in the culture medium, (3) compare the effect of pH on the in vitro dissolution of chrysotile under biological and abiotic conditions. Over the course of 18 days, Talaromyces sp. was grown in the presence of asbestiform chrysotile (NMNH 261) in Czapek media containing MES buffer (pH 5.5), half with and half without FeSO4. Because the pH dropped to approximately 4.5 during fungal growth, an abiotic experiment was performed to mimic the change in solution pH with time by adding 2M HCl. Samples were measured for magnesium and silicon concentrations and pH, and growth in culture flasks was visually tracked and photographed. Regardless of the supply of bioavailable iron, chemical weathering rates of chrysotile were nearly identical whether dissolution was biologically or abiotically driven. This indicates that dissolution is promoted by acidity, rather than direct biological mechanisms, and that Talaromyces sp. was responsible for chrysotile weathering only through the production of organic acids. Furthermore, XRD and SEM analysis of chrysotile fibers showed no structural changes, indicating that Talaromyces sp. may not have any direct potential applications for bioremediation of chrysotile asbestos.

The resulting interconnection of the two Americas is an ecologically important event reported to have prompted the Great American Biotic Interchange between these once isolated landmasses. However, recent examinations of tectonic, molecular, and fossil evidence have refined this timeline, suggesting that the rise of the Isthmus and CAS closure may have occurred earlier than previously thought. Numerous paleoceanographic studies have demonstrated that the neodymium (Nd) isotope signatures of microscopic fish teeth/debris and detrital fractions in deep sea sediments reflect the Nd-isotope composition of bottom waters in the region they were deposited. Subsequently, this Nd can be used as a water mass tracer for paleo-circulation. While this proxy has been widely applied to deep sea sediment cores and even the CAS closure story, its application to samples from outcrops of marine strata that are now aerially exposed is not as well established, particularly in the tropics. Here, we investigate the potential for marine sediments from the seaway itself to preserve water mass Nd signatures that may help to further elucidate the shoaling history of the CAS. This investigation was facilitated by a field expedition to a number of geographically distinct localities in the Azuero Peninsula, Panama in June of 2015. During the expedition, several outcrops of marine stratigraphic successions were described for the first time and corresponding in-situ deep marine, hemipelagic sandstone, and turbiditic conglomeratic sediments were collected. The isolation of fish microfossils from these sediments and analysis of rare earth element compositions and Nd-isotopic ratios within them enables a direct comparison to those from other exposures across Panama and deep marine signatures from the Pacific and Caribbean. This comparison should further allow determination of the origins of the Nd signal recorded in Azuero, as well as whether or not the specimens may be used as a peri-continental complement to circulation reconstructions from deep sea sediments and thus provide a more accurate depiction of the depth of the isthmus during the Cenozoic.

Parasitoids have an intermediate trophic position between parasites (the host is not killed) and predators (the prey is killed outright). The targeted host gradually succumbs while it spends most of its life history being incrementally consumed by the parasitoid. Parasitoids can be microorganisms (entomophthoralean pathogens), plants (mistletoes), fungi (cordycipitaceous hypocrealeans), invertebrates (Sacculina barnacles) or vertebrates (lampreys). However, it is the insect fossil record that is the best archive for parasitoids, which documents the mid-Mesozoic Parasitoid Revolution in detail. This event begins during the mid Early Jurassic and is represented by a proliferation of parasitoid Hymenoptera (wasps) that consisted eventually of 56 families recognized in the fossil record, later supplanted by 10 fossil families of parasitoid Diptera (true flies). Insect parasitoidism began as ectoparasitoidism in wasps and flies, targeting the integument of much larger hosts, mostly caterpillars or large adult insects, later evolving into endoparasitoidism in which internal host organs were consumed from within. During the Cretaceous, a major fungal diversification event occurred among certain fungi that also targeted insects, resulting by early Eocene times, in the perfection of zombification, by which parasitoid fungal hyphae enter the brain of a host adult ant, rearranges its brain tissue, and effect unusual behaviors. The most profound result of the Parasitoid Revolution was the contrast between pre-parasitoid ecosystems characterized by resource-driven, bottom --> up regulation of productivity, and post-parasitoid ecosystems that were consumer-driven by top --> down regulation. One explicit manifestation of this trophic shift comes from food-web analyses of the early Eocene Lake Messel ecosystem, in which the top consumer of the lacustrine portion of the food web is a crocodile whereas the top consumer of the terrestrial portion of the food web is a parasitoid fly.

AN - 1769967764; 2016-018858 AB - The Medusae Fossae Formation (MFF), Mars, is an enigmatic layered and intensely eroded deposit generally found between approximately 130 degrees E and 230 degrees E and 15 degrees S and 15 degrees N. Multiple hypotheses have been proposed for the precise origin of the MFF, from ancient polar deposits to reworked volcanic ash. Outliers of MFF have been identified tens of kilometers away from the continuous MFF outcrops, suggesting that the presently observed MFF deposits are remnants of a larger, more continuous deposit. Knowing the previous extent of the MFF would provide information about erosional processes operating on Mars since the Hesperian Period, and help to differentiate between possible origins of the MFF. To constrain the previous extent of the MFF, we developed a weighted matrix of observable morphologies to identify isolated outcrops of MFF. These characteristics are best seen at resolutions better than 250 m/pixel. Characteristics are identified as "excellent," "very good," or "good." An MFF outcrop can be confidently identified by any one of the following options: 1) one "excellent" characteristic; 2) two "very good" characteristics; 3) one "very good" characteristic and two "good" characteristics; 4) or at least four "good" characteristics. An "excellent" observation consists of superposed layered materials, with each layer containing yardangs with distinct orientations. "Very good" characteristics include finding a deposit containing yardangs, showing crenulated margins or visible layers. Observations comprising "good" characteristics include: 1) an unconformable, mantling deposit; 2) consistent surface texture; 3) geographic continuity with known MFF deposits; 4) proximity to known MFF deposits; or 5) aligned depressions (grooves or troughs) suggesting removal of material. Identification and mapping of formerly unidentified MFF outcrops suggests that the MFF may have once comprised almost twice its current volume, requiring massive redistribution of material on Mars.

An understanding of how these processes occur in each unique case has both scientific and commercial impact for the identification and authentication of diamonds. The underlying physical systems that drive these diamond color changes may also manifest changes in other measurable properties, such as luminescence. We have investigated luminescence in two classes of diamond noted for displaying color changes: (1) pink/brown diamonds, and (2) 'chameleon' diamonds. The defect centers responsible for diamond color in these cases are not well understood; we examined luminescence behaviors seeking to learn more about electronic transitions underlying the diamond color, and color-change. Some pink/brown diamonds demonstrate two distinct phases of photochromism--one induced by excitation in the visible domain, and one sensitive to ultraviolet and infrared light. The latter induces luminescence from diamond defects that do not otherwise interact with the pink color center. A new survey shows that this luminescence is visible in a wide range of pink/brown diamonds, and involves a larger number of defects than had been previously observed. We will discuss the implications of these results for the current understanding of pink diamond color, and its relationship with brown color in diamonds. 'Chameleon' diamonds show characteristic fluorescence peaking near 560 nm. This band is strongly temperature-sensitive, suggesting a possible association with the diamonds' thermochromism. 560 nm-band phosphorescence following UV exposure suggests a thermal release of trapped charge carriers from several distinct traps. Infrared light can also empty the trap states, and may be used to measure lifetimes of long-lived states.

Emerald from the Hiddenite area is hosted by quartz-carbonate Alpine-type veins that developed within Precambrian migmatitic schists and gneisses. Overshadowed by the presence of emerald is the occurrence of the Cr-bearing gem variety of spodumene known as hiddenite. The two gem minerals are closely associated throughout the area and typically occur within the same mineral deposit. This rare and unique association of emerald (beryl) and hiddenite (spodumene) is unprecedented and is unknown from emerald deposits and Alpine-type veins worldwide. The gem-bearing veins of the Hiddenite area formed from hydrothermal fluids under low temperature (<250 degrees C) and low pressure ( approximately 1 kb) conditions. Based on geochemical studies, the heterogeneous migmatitic rocks appear to be the most likely source of Cr for the emerald and hiddenite mineralization. Local outcroppings of the Rocky Face granitic pluton and unexposed granitic pegmatites have been proposed as possible sources of Be for the crystallization of emerald, however recent examination of "pegmatitic" leucosomes within the migmatite terrane have revealed the presence of aquamarine thereby suggesting that pre-migmatitic rocks may have been the most important contributor of Be for the crystallization of emerald. Presently, there are no rocks exposed that could be considered as likely sources of Li for the crystallization of hiddenite. The exploration for new gem-bearing Alpine-type veins in the Hiddenite area is hindered by the lack of suitable outcropping of migmatite and continues to rely heavily upon the haphazard examination of the overlying saprolite layer. Current and past workings of known emerald and hiddenite occurrences suggest that the gem-bearing vein system may be restricted to a northeast-southwest trending belt of unknown width and length. Within individual workings, differences in the crystal morphology of quartz, rutile and pyrite, coupled with differences in the assemblages of carbonate and sulfide minerals can serve as useful indicators of emerald or hiddenite mineralization.

We describe standardized measurement and data collection protocols in three sections: (i) locating fungus-farming ants in the field; (ii) collecting whole colonies of fungus-farming ants; and (iii) maintaining living colonies of fungus-farming ants in the laboratory. We provide lists of necessary equipment and materials, including information on where they can be acquired.

Quantifying the causes and spatial patterns of interannual variability in SAV abundance is critical to understanding the dynamics of SAV in complex estuaries. We applied empirical orthogonal function (EOF) analysis to quantify the temporal synchronicity among embayments within each of 3 salinity zones (oligohaline, mesohaline, and polyhaline) of Chesapeake Bay. EOF analysis extracts shared modes of variation among the embayments in each zone. The amount of synchronicity differed among zones, and embayments were most synchronous within the polyhaline zone. The extracted modes of variation showed that fluctuations in SAV abundance are not synchronized among the salinity zones. We detrended the modes of common variation in SAV abundance for each salinity zone and then used cross-correlation analysis to compare the detrended modes to detrended water quality variables (dissolved organic carbon, suspended solids, chlorophyll a, Secchi depth, river nitrogen load, temperature, and salinity). The water quality variables that were significantly related to SAV abundance differed among salinity zones. Chlorophyll a levels in months when seed germination and shoot production rates are high were important negative predictors in the oligohaline and polyhaline zones, possibly because young SAV plants are especially sensitive to even short-term disturbances. As the SAV communities in the 3 salinity zones have different year-to-year dynamics and different responses to stressors, conservation, restoration, and management plans should be tailored to each community.

In A. cauliformis, there was a tight coupling of symbiont and host metabolism across treatments, and changes in growth rate were correlated more with shifts in symbiont delta super(13)C and delta super(15)N values than with shade treatment. In contrast, symbiont and host C metabolism were weakly coupled in A. fulva, and the growth of this species was not correlated with shifts in symbiont delta super(13)C and delta super(15)N values. In addition, although photosymbiont metabolism was an important driver of shifts in holobiont C and N metabolism of both host species, host and photosymbiont C metabolism were only correlated in A. cauliformis. Thus, although both species host stable, abundant, and similar photosymbiont communities, each host forms a unique mutualism with its symbionts. These 2 host species may be on different evolutionary trajectories, potentially allowing each to exploit novel niche space in coral reef ecosystems. This study provides data in support of the hypothesis that these symbioses represent a dynamic balance of costs and benefits and provides evidence that, because these costs and benefits are highly speciesspecific, not all species will respond similarly to environmental fluctuations.

These areas also tend to be heavily impaired by eutrophication from nutrient over-enrichment which increases the occurrence and severity of hypoxia and pH cycles. We used laboratory experiments to investigate the effects of diel-cycling dissolved oxygen (DO) and co-varying diel-cycling pH on infections of Perkinsus spp. and hemocyte activity in the eastern oyster Crassostrea virginica. Perkinsus marinus is the protistan parasite that causes Dermo disease in oysters. Severe diel-cycling DO increased the acquisition and progression of Perkinsus infections during exposure, and had a legacy effect the next year. Diel-cycling pH did not significantly affect infection dynamics either on its own or in combination with diel-cycling DO. Diel-cycling DO and pH both individually and in conjunction stimulated hemocyte activity, although this stimulated activity may not be effective at preventing Perkinsus infection. The magnitude of cycling conditions is an important consideration when choosing restoration sites, as severe cycling may hinder the re-establishment of oysters by creating areas that serve as reservoirs for parasites that can infect nearby populations.

Laboratory microcosm trials (Gilmour et al. 2013) and early field trials show that activated carbon (AC) can effectively increase partitioning of both inorganic Hg and methylmercury to the solid phase. Sediment-water partitioning can serve as a proxy for Hg and MeHg bioavailability in soils. One consideration in using AC in remediation is its potential impact on organisms. For mercury, a critical consideration is the potential impact on net MeHg accumulation and bioavailability. In this study, we specifically evaluated the impact of AC on rates of methylmercury production and degradation, and on overall microbial activity, in 4 different Hg-contaminated salt marsh soils. The study was done over 28 days in anaerobic, sulfate-reducing slurries. A double label of enriched mercury isotopes (Me (super 199) Hg and inorganic (super 201) Hg) was used to separately follow de novo Me (super 201) Hg production and Me (super 199) Hg degradation. AC amendments decreased both methylation and demethylation rate constants relative to un-amended controls, but the impact on demethylation was stronger. The addition of 5% (dry weight) regenerated AC to soil slurries drove demethylation rate constants to nearly zero; i.e. MeHg sorption to AC almost totally blocked its degradation. The net impact was increased solid phase MeHg concentrations in some of the soil slurries with the highest methylation rate constants. However, the net impact of AC amendments was to increase MeHg (and inorganic Hg) partitioning to the soil phase and decrease concentrations in the aqueous phase. AC significantly decreased aqueous phase inorganic Hg and MeHg concentrations after 28 days. Overall, the efficacy of AC in reducing aqueous MeHg was highest in the soils with the highest MeHg concentrations. The AC addition did not significantly impact microbial activity, as assessed by CO2 production and sulfate depletion, in two of the four soils, but resulted in a up to a 40% decrease in two other soils. AC amendment has little effect on slurry pH, but decreased aqueous Fe, sulfide and DOC concentrations.

The discovery of a fossil representative of this genus suggests that Latiblattella was more widely distributed in the Eocene. The Eocene American cockroach fauna is mostly comprised of what are today, cosmopolitan genera while the extant genus Latiblattella Hebard, 1917 is restricted in its geographical distribution to Central America, Mexico, Florida and Arizona. The discovery of Latiblattella avita, in combination with the recent description of Cariblattoides labandeirai Vrsansky et al., 2012, also documents the presence of rather derived representatives of the family Ectobiidae as early as the Middle Eocene.

They have been studied for their high cation exchange capacity and redox properties, with potential applications in environmental remediation and batteries. Synthetic triclinic and hexagonal birnessites are commonly used as analogues for natural layered Mn oxides. We have studied and compared a variety of natural and synthetic birnessite-like phases, using X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and Fourier transform infrared spectroscopy (FT-IR). Synthetic birnessites studied include triclinic Na-, Ca-, K-, and Ba-birnessites. Synthetic hexagonal H-birnessites studied were derived from triclinic Na-birnessite powders placed in aqueous solutions at pH 2 or 3, or in solutions buffered at pH 7 using HEPES. Natural samples included Mn oxides from a Tennessee stream and several acid mine drainage sites in Pennsylvania. All natural samples were identified as birnessites/buserites using XRD. EDS showed that all natural Mn samples contained Ca. Although many of the natural samples yielded indistinguishable XRD patterns, XPS revealed that most samples contain Mn in all three oxidation states, with differences in the ratios of Mn (super 2+) , Mn (super 3+) , and Mn (super 4+) . Thus, XPS provided new insights beyond the typically reported average oxidation states (AOS) for Mn, as conventionally measured through titrations. For the samples of synthetic hexagonal H-birnessite formed at different solution pH, we found that as pH decreased, the amount of Mn (super 3+) also decreased, whereas the Mn (super 4+) content increased. For synthetic triclinic birnessite samples, the degree of disproportionation of Mn (super 3+) varied with the interlayer cation despite all samples yielding similar XRD patterns. Our research suggests that multiple techniques may be necessary to properly characterize Mn oxides.

It has also become recognized that contemporary extinctions have a strong biogeographic signal, with island and endemic faunas being particularly hard hit. Meaningful comparisons of rates, ecological and taxonomic structure, and potential causal mechanisms of the modern extinction with those in the past depend on accounting for inherent biases present in the fossil record. Specifically, taphonomic biases should impact our understanding of preserved spatial patterns that are necessary to correctly interpret mechanisms of past extinctions. It is well recognized that the fossilization potential of terrestrial animals varies spatially, based on a range of climatic, topographic, and other environmental factors. For example, areas with caves and other karst features should preferentially preserve many mammals, since they act as traps for carcasses. Particular soil chemistries or local depositional settings may inhibit or promote fossilization over multiple time scales. Spatial variability of taphonomic processes should strongly but predictably overprint biological signals of animal abundance, diversity, and range. Placing taphonomic variables in an explicit spatial framework, where each map unit represents a specific combination of preservational controls, will produce a "landscape taphonomy" that will allow us to produce a "future fossil record" of living terrestrial vertebrates on the landscape scale, based on their spatial distribution and ecological properties and on the spatial variability of key taphonomic variables. This, in turn, will allow improved understanding of extinction patterns and mechanisms in the geological past.

We don't know how the tendencies and characteristics of the members end up channeled into a new roll within the context of the whole colony, nor do we know how new discrete variation arises from homogeneous and often clonal members. What we do know is that similar biological solutions to these two seemingly difficult problems have evolved independently multiple times in a wide range of organisms from bryozoans to bees. In this talk I propose a hypothetical mechanism for the evolution of polymorphism (division of labor), termed the "life-history ratchet" and explore its utility in understanding the evolution of cheilostome bryozoan polymorphism. This hypothesis explains the linkage between increases in polymorphism and reductions in the frequency of reproductive specialization through the repeated evolution of novel colony-level life-history strategies. With the origin of a novel polymorph type, novel life-history strategies become accessible which may be advantageous in the highly competitive encrusting environments where many bryozoans live. For example, primitive monomorphic species have a repertoire of life histories limited by the capabilities for asexual and sexual propagation of their members. After the origin of the initial reproductive polymorph, the life-history of the colony can vary independently of its members as a function of the relative frequencies of reproductive polymorphs in the colony. The life-history ratchet explains both how characteristics of solitary ancestors constrain the colony's life-history and how reproductive specialization breaks this constraint by permitting new life-history strategies.

In June 2014, surface sediment (0-1 cm) was collected using a grab sampler from two parallel shore-normal transects offshore of Kuala Terengganu, peninsular Malaysia. Each transect (ca. 45 km in length and ranging from 5 to 60 m water depth) was composed of eight stations with three replicate samples at each station. At least 300 foraminiferal specimens were picked from the 150-1000 mu m size fraction of each replicate sample and ca. 130 species were identified. Numerical analysis of dead (unstained) foraminifera shows three groups of samples that are related to depth and substrate. The shore proximal group (ca. 5-30 m, shelly sand substrate) is dominated by Amphistegina lessonii (19%) and Amphistegina radiata (17%), the shore intermediate group (30-50 m, sandy mud substrate) is dominated by Assilina ammonoides (11%), Heterolepa dutemplei (10%), and Asterorotalia milletti (9%), and the shore distal group (50-60 m, muddy substrate) is dominated by A. milletti (16%), H. dutemplei (16%), Elphidium advenum (9%), Hanzawaia nipponica (7%), and Textularia sp. (7%). Species diversity (S) and abundance of living (stained) foraminifera show little variation throughout each transect--the former is ca. 35 per sample and the latter never exceeds 10% of a sample. In June 2015, an additional surface sample (three replicates per sample) for each transect was collected 92 kilometers offshore at a depth of 60 m. This study provides modern analogues for interpretation of paleoenvironmental changes in the Holocene sedimentary record of the western Sunda Shelf.

Most recent efforts have focused on analytical access to the existing record, but systematic improvements can also be made in the record itself. Specifically, sets of isotaphonomic samples can be used to standardize many collecting and preservational biases. This allows more robust, detailed comparisons to be made over broad spatiotemporal scales. We propose that vertebrate microfossil bonebeds (VMBs) represent one such sampling regime. These specimen-rich, locally restricted concentrations of small vertebrate fossils are especially valuable sources for small and rare taxa. More importantly, they occur throughout the terrestrial record, only form under a limited set of taphonomic settings, and provide high sample sizes that afford opportunities to assess abundances and diversities. We made and analyzed VMB collections from the Cretaceous Cloverly and Judith River formations to assess patterns of diversity, abundance, and paleoecology. In addition to finding several undiscovered taxa and refining spatiotemporal ranges for others, we could make much finer-scale comparisons with penecontemporaneous VMBs than is typically possible for Mesozoic terrestrial faunas. We also attempted to address the potential biases and difficulties associated with VMB abundance data. Differentiating between taphocoenotic and biocoenotic effects remains a challenge, along with the differing contributions to the biocoenotic sample from organisms with unequal tooth replacement rates. Once solved, VMBs will be a powerful tool for examining geographic, environmental, and temporal variations in paleoecosystems across a wide swath of geologic time.

However, given the basin architecture and depositional setting, correlations between localities are difficult without geochronology. Here we present new high precision ID-TIMS U-Pb zircon dates from five air-fall ash deposits from Westwater (n = 3) and Henrieville (n = 2) that obey stratigraphic superposition and precisely constrain the ages of these two floras. Three air-fall ashes from the Westwater locality record weighted mean Th-corrected (super 206) Pb/ (super 238) U dates of 97.949 + or - 0.037/0.12 Ma, 97.943 + or - 0.023/0.12 Ma, and 97.601 + or - 0.049/0.13 Ma, providing the first U-Pb dates from this locality. Two ash beds from the Henrieville locality record weighted mean Th-corrected (super 206) Pb/ (super 238) U dates of 95.070 + or - 0.036/0.12 Ma and 94.879 + or - 0.032/0.11 Ma. The new dates indicate that the two floras are separated by ca 2.5 Ma and are both within the Cenomanian. The assemblage of fossil plants collected from the mudstone and ash-bed localities at Westwater show no compositional overlap, despite the presence of 28 distinct morphotypes. This lack of compositional overlap is repeated between the mudstone facies from the Westwater and Henrieville localities, where two different morphotypes of "Liriodendron" are the taxa in common. The species incongruence at Westwater is likely due to rapid colonization of early successional plants post deposition of the volcanic ash. For the mudstone floras at Westwater and Henrieville, the different floral composition may be due to rapid species evolution during the rise of angiosperms, the influence of climate in the mid-Cretaceous, the expression of high regional diversity of localities separated by 300 km, or a highly partitioned floodplain vegetation. Estimated sediment accumulation rates from the new radioisotopic dates, combined with existing proxy records for pCO (sub 2) , suggest that the rise in pCO (sub 2) preceding Ocean Anoxic Event 2 (OAE2) began 513 ka (range from 384 to 641 ka) prior to the positive delta (super 13) C excursion that defines the event. This estimate from terrestrial rocks is within error of estimates for the timing of changes in delta (super 34) S (sub sulfate) (570 ka; range from 420 to 814 ka) in marine sections at the GSSP for the Cenomanian-Turonian boundary. The overlap indicates synchronous perturbation of marine and terrestrial environments related to an increase in pCO (sub 2) prior to the onset of OAE2, providing further support for the volcanic initiation hypothesis.

It begins with an overview of the geological setting of the city and development of the Mall. Each federal monument or building on the tour is briefly described, followed by information about its exterior stonework. The focus is on masonry buildings of the Smithsonian Institution, which date from 1847 with the inception of construction for the Smithsonian Castle and continue up to completion of the National Museum of the American Indian in 2004. The building stones on the tour are representative of the development of the American dimension stone industry with respect to geology, quarrying techniques, and style over more than two centuries. Details are provided for locally quarried stones used for the earliest buildings in the capital, including Aquia Creek sandstone (U.S. Capitol and Patent Office Building), Seneca Red sandstone (Smithsonian Castle), Cockeysville Marble (Washington Monument), and Piedmont bedrock (lockkeeper's house). Following improvement in the transportation system, buildings and monuments were constructed with stones from other regions, including Shelburne Marble from Vermont, Salem Limestone from Indiana, Holston Limestone from Tennessee, Kasota stone from Minnesota, and a variety of granites from several states. Topics covered include geological origins, architectural design considerations, weathering problems, and conservation issues.

We report here on cranial and postcranial remains that can be attributed to titanosaurian sauropods. This material is of considerable interest in view of the relative scarcity of sauropod fossils from the Upper Cretaceous of Central Asia. An incomplete braincase originally assigned to the ceratopsian Turanoceratops tardabilis actually belongs to a derived titanosaurian. It shares a number of features (including broad basal tubera and presence of wide depression between basal tubera) with braincases of various derived titanosaurian taxa from Asia and South America. Computed tomographic (CT) scanning of the braincase permitted digital reconstruction of a partial endocast. Overall, this endocast resembles those of other sauropods, although the pituitary fossa is considerably swollen. As in other derived titanosaurians, the abducens nerve passed lateral to the pituitary fossa. The inner ear resembles that of some other titanosaurs in having a very short lateral semicircular canal and that the anterior semicircular canal is only slightly longer than the posterior one. Isolated sauropod teeth from Dzharakuduk have slender, 'pencil-shaped' crowns, which often bear high-angle apical wear facets. The caudal vertebrae are gently opisthocoelous rather than procoelous, as is typically the condition on at least the anterior caudals in many other titanosaurs. An anterior caudal vertebra shows extensive pneumatization of its neural arch. The sauropod remains from the Bissekty Formation establish the presence of titanosaurians in Central Asia during the Turonian.

H. castanedaii, represented by a partial skull, mandible, and some postcranial remains, is characterized by (1) unique dental formula, with 0/3i, 1/1c, 1/1p, and 3/3 m; and (2) lower canines with subtriangular transverse section at the base. Hilarcotherium differs from the equatorial Uruguaytheriinae genera Xenastrapotherium and Granastrapotherium in (1) having three lower incisors; (2) the diagonal implantation of the lower canines; (3) lower molars with lingual cingulid; (4) the presence of the hypocone in the third upper molar; and (5) the presence of an anterolingual pocket in the fourth upper premolar. Our phylogenetic analysis supports the monophyly of the subfamilies Astrapotheriinae and Uruguaytheriinae. Within the latter, we confirm the monophyly of the neotropical clade (Hilarcotherium, Xenastrapotherium, and Granastrapotherium). H. castanedaii shows some plesiomorphic features such as the aforementioned presence of the i3 and the developed hypocone in the last upper molar. Its estimated body mass (1303 kg) is intermediate among Astrapotheriidae.

AN - 1703690300; 2015-078933 AB - The extent of morphologic innovation during the Ediacaran-Cambrian diversification of animals was unique in the history of metazoan life. This episode was also associated with extensive changes in the redox state of the oceans, in the structure of benthic and pelagic marine ecosystems, in the nature of marine sediments, and in the complexity of developmental interactions in Eumetazoa. But did the phylogenetic and morphologic breadth of this episode simply reflect the unusual outcome of recurrent evolutionary processes, or was it the unique result of circumstances, whether in the physical environment, in developmental mechanisms, or in ecological interactions? To better characterize the uniqueness of the events, I distinguish among these components on the basis of the extent of sensitivity to initial conditions and unpredictability, which generates a matrix of possibilities from fully contingent to fully deterministic. Discriminating between these differences is important for informing debates over determinism versus the contingency in the history of life, for understanding the nature of evolutionary theory, and for interpreting historically unique events.

These species exhibit a noticeable antitropical distribution in the Northern and Southern hemispheres, respectively. The evolutionary history of elephant seals, especially in regard to establishing this antitropical pattern, is poorly known. Nearly all fossils of the genus are isolated remains from the Pleistocene of California (M. angustirostris) and South Africa (M. leonina). Here, we describe new fossil material of Mirounga sp. (incomplete maxilla, dentary, and humerus), from the middle to late Pleistocene of Antofagasta Region, northern Chile. This material constitutes the first fossil occurrence of this species in South America and suggests that during part of the Pleistocene, phocids coexisted with otariids along the eastern edge of the South Pacific Ocean, which contrasts with the current biogeographic pattern in this ocean basin, providing new information about the structure of the pinniped community during the Pleistocene of South America.

As alteration progresses, the total abundance and magnesium content of phyllosilicates increases. In this paper we present the results of a coordinated spectral-mineralogical study of a well-characterized suite of CM/CI meteorites that range from 60 to 90% alteration. By acquiring spectra the same meteorite powders as Howard et al. (Howard, K.T., Benedix, G.K., Bland, P.A., Cressey, G. [2009]. Geochim. Cosmochim. Acta 73, 4576-4589; Howard, K.T., Benedix, G.K., Bland, P.A., Cressey, G. [2011]. Geochim. Cosmochim. Acta 75, 2735-2751) and Bland et al. (Bland, P.A., Cressey, G., Menzies, O.N. [2004]. Meteorit. Planet. Sci. 39(1), 3-16), we are able for the first time to directly correlate mineralogy with features in reflectance spectra. At visible/near-infrared wavelength, the presence of a 0.7-mu m charge transfer band is indicative of aqueous alteration. However, not all altered CM/CI meteorites exhibit this feature; thus the lack of a 0.7 mu m absorption band in asteroids does not necessarily signify a lack of aqueous alteration. Furthermore, the position and depth of 0.7-mu m charge transfer band shows no correlation with the mineralogical changes associated with aqueous alteration. Similarly, the near-infrared slope, which is not directly related to the mineralogic progression associated with increasing alteration, is not unambiguously related to degree of alteration in the CM/CI meteorites studied. However, the mid-infrared reflectance spectra of CM/CI meteorites contain a broad absorption feature in the 10-13-mu m region, which is a convolution of vibrational features due to Mg-rich phyllosilicates and unaltered olivine. The overall feature continuously changes with total phyllosilicate abundance from a shorter wavenumber/longer wavelength peak (815 cm (super -1) , 12.3-mu m) for less altered meteorites to a longer wavenumber/shorter wavelength (875 cm (super -1) , 11.4-mu m) peak in the highly altered meteorites, with roughly equal spectral contributions producing a doublet in intermediately altered meteorites, Using the results from the mid-infrared analyses of meteorite spectra, it is possible to estimate the degree of alteration on dark primitive asteroids. We find Asteroid (24) Themis to have a 1000-700 cm (super -1) (10-13-mu m) peak at longer wavelengths suggesting Themis has a complex surface mineralogy with approximately 70 vol.% phyllosilicates and 25 vol.% anhydrous silicates.

Here, we describe two femora that provide additional information on the diversity of small-bodied theropods in the Gondwanan Mid-Cretaceous. An almost complete femur (ROM 64666) represents a noasaurid theropod based on the presence of an elongate anteromedial flange that arises from the distal shaft and terminates proximal to the distal end of the bone; osteohistological analysis indicates that it was from a juvenile individual. It is possible that this femur represents a juvenile Deltadromeus, which is recovered as a putative noasaurid in some phylogenetic analyses. Nevertheless, as the affinities of Deltadromeus are debated, this femur currently represents the first definitive record of a noasaurid from northern Africa and one of the few records of this clade from the early Late Cretaceous. Moreover, if this specimen is not a juvenile Deltadromeus then it probably represents a new addition to the Kem Kem theropod assemblage. A second partial femur (ROM 65779) can be identified only as an indeterminate averostran theropod. It is similar in size to ROM 64666, but the presence of an external fundamental system (EFS) indicates that it pertained to a small-sized adult individual. These observations indicate that the two femora described herein are from different theropod taxa, thereby demonstrating that at least one additional small-bodied theropod taxon was present in the Kem Kem fauna, adding to the already high theropod species-richness of this unit.

The along-strike variations in volatiles result from the complex geodynamical setting of the area, including numerous transform faults, variations in ridge depth, melting degree, and source composition. The strongest gradient is centered on 1.7 degrees N and encompasses an increase of H (sub 2) O, Cl, and F contents as well as high F/Zr ratio spatially coincident with radiogenic isotope anomalies. We interpret these variations as source enrichment due to the influence of the nearby high-mu -type Sierra Leone plume. South of the St. Paul fracture zone, H (sub 2) O and F contents, as well as H (sub 2) O/Ce and F/Zr ratios, decrease progressively. This gradient in volatiles is consistent with progressive dilution of an enriched component in a heterogeneous mantle due to the progressive increase in the degree of melting. These two large-scale gradients are interrupted by small-scale anomalies in volatile contents attributed to (1) low-degree melts preferentially sampling enriched heterogeneities near transform faults and (2) local assimilation of hydrothermal fluids in four samples from dredge 16D. Finally, 20 RC2806 samples described as "popping rocks" during collection do not show any difference in volatile content dissolved in the glass or in vesicularity when compared to the RC2806 "nonpopping" samples. Our observations lead us to question the interpretation of the CO (sub 2) content in the highly vesicular 2pi D43 "popping rock" as being representative of the CO (sub 2) content of undegassed mid-ocean ridge basalt.

AN - 1682206712; 25978686 AB - Understanding how ecological interactions mitigate the impacts of perturbations such as pesticides in biological communities is an important basic and applied question for ecologists. In aquatic ecosystems, new evidence from microcosm experiments suggests that submerged macrophytes can buffer cladocerans from pulse exposures to the widely used insecticide malathion, and that mitigation increases with macrophyte density. However, whether these results scale up to more complex aquatic communities where ecological interactions such as competition can alter toxicity is unknown. Further, macrophyte abilities to mitigate different insecticide exposure scenarios (i.e. single versus repeated pulses) have never been tested. To address these gaps, we performed a factorial mesocosm experiment examining the influence of four macrophyte treatments (0, 10, 50, or 100 Elodea Canadensis shoots planted per mesocosm) crossed with three malathion exposure scenarios (no insecticide, single pulse, repeated pulses) on aquatic communities containing zooplankton, phytoplankton, periphyton, two snail species, and larval amphibians. In the absence of macrophytes, single malathion pulses caused short-term declines in cladoceran abundance followed by their rapid recovery, which precluded any indirect effects (i.e. trophic cascades). However, repeated malathion pulses caused cladoceran extinctions, resulting in persistent phytoplankton blooms and reduced abundance of one snail species. In contrast, with macrophytes present, even at low density, malathion had no effect on any taxa. We also discovered novel effects of macrophytes on the benthic food web. In the two highest macrophyte treatments, we observed trends of reduced periphyton biomass, decreased abundance of one snail species, and decreased amphibian time to and mass at metamorphosis. To our knowledge, this is the first evidence of negative submerged macrophyte effects on amphibians, a taxa of global conservation concern. Our findings suggest that facilitating macrophytes could be an important strategy for buffering freshwater communities from insecticides, though consideration of their impacts on animal species is necessary.

Here, we evaluate recent trends and developments in island and coastal archaeology and discuss how research over the last decade has changed and continued to illuminate the antiquity of maritime adaptations, human dispersals, historical ecology, and many other issues on a global scale. With rising seas and marine erosion threatening island and coastal archaeological sites around the world, archaeologists face urgent challenges in the coming decades as we continue to promote research and conservation of the global island and coastal archaeological record.

We monitored kit foxes on the 40 km super(2) proposed site for the Topaz Solar Farms (TSF) in San Luis Obispo County, California, which consisted of 76% agricultural fields and 24% grasslands. Prior to construction of the solar facility in December 2011, we used professionally trained dog-handler teams to conduct non-invasive genetic surveys annually from 2009 to 2011. We analyzed mtDNA to identify species, zinc finger genes for sex determination, and microsatellite loci to define individuals. We identified 45 individuals from 351 fresh scat samples (26 females, 18 males, and 1 individual of unknown sex), and recaptured 5 individuals between years. Kit foxes predominantly used the grasslands and rarely used agricultural fields. Samples from the TSF population had similar levels of genetic diversity to 2 areas less than 20 km away in the northern end of the Carrizo Plain National Monument. Capwire and LDNe estimates of population size using samples collected during annual November surveys indicated that similar to 33 individuals used the TSF over a 3 yr period. The relatively high population estimate, low recapture rates, and similar genetic diversity to 2 nearby locations suggest that individuals using the TSF site are part of a larger population using the surrounding landscape. Our study provided baseline data that, when coupled with future surveys, will help assess the effects on San Joaquin kit foxes of solar facility construction and habitat regeneration on agricultural lands removed from production.

Hematite is known to incorporate structural OH (super -) and water, and the requisite charge balance is achieved by iron vacancies. Prior researchers have suggested that the defective hematite structures form unique phases called "protohematite" and "hydrohematite." Infrared and Raman spectroscopic studies have assigned a lower-symmetry space group to "hydrohematite" (R3c) relative to that of stoichiometric hematite (R3(combining macron)c). However, the existence and structure of these phases have been contentious, largely due to the lack of in situ X-ray diffraction dataHere we present a new structure refinement for "hydrohematite" precipitated hydrothermally at 200 degrees C in a monoclinic space group (I2/a) using time-resolved synchrotron X-ray diffraction (TR-XRD) data collected during the in situ hydrothermal precipitation of akaganeite and its transformation to stoichiometric hematite. Distinct peak splitting was observed in the "hydrohematite" diffraction patterns, indicating a violation of the threefold rotational symmetry. A monoclinic unit cell with parameters of a = 7.3951(10), b = 5.0117(5), c = Aa) beta , = 95.666(5) degrees provided a good fit and significant reduction in X (super 2) and R (sub wp) relative to space group R3c. Rietveld analyses revealed that water concentrations in the first-formed crystals of "hydrohematite" were comparable to water contents of akaganeite and goethite. Thus, the hydrothermal transformatiation of akaganeite to "hydrohematite" promoted not by dehydration but by reconstruction of the oxygen framework.

Although the fossil record of oribatid mites can be traced to the Early Devonian, the paleoecology of oribatid mites during the deep geological past remains poorly understood. Remarkably good preservation of tunnel networks in a permineralized conifer wood specimen is described from the Early Permian of Germany. This fossil provides evidence for four aspects of oribatid mite feeding habits. First, there is preferred consumption of the more indurated tissues from growth-ring cycles. Second, tracheids were targeted for consumption. Third, feeding on tissues resulted in fecal pellet accumulations at the bottoms of tunnels. And fourth, the absence of feeding on ambient decomposing fungi such as necroses and rots, but rather the processing of pristine plant tissues, indicate the presence of a self-contained, microorganismic gut biota. These rather specialized feeding habits allowed oribatid mites a prominent role in the decomposition of digestively refractory plant tissues in Early Permian ecosystems.

AN - 1664195075; PQ0001241248 AB - Polyphosphate is a quantitatively important and dynamic component of the sedimentary phosphorus in many lakes. Kenney et al. correctly note that we misrepresented their data on polyphosphate in Lake Apopka in our article on the phosphorus composition of subtropical lake sediments, and we regret this error. However, we reiterate that their operationally defined heat extraction procedure overestimates polyphosphate in lake sediments because it includes phosphorus from a number of non-polyphosphate sources. In contrast, our measurements by solution super(31)P NMR spectroscopy provide direct quantification of polyphosphate in Lake Apopka sediments and are therefore closer to the true values. Future studies addressing the origins and dynamics of polyphosphate in the environment should employ analytical procedures that unequivocally identify and quantify polyphosphate.

The texture and composition of silicate and opaque minerals from each observed FeO-rich (type II) chondrule, and a representative number of FeO-poor (type I) chondrules, were studied to build a substantial and self-consistent data set. The average abundances and standard deviations of Cr (sub 2) O (sub 3) in FeO-rich olivine phenocrysts are consistent with previous work that the CR chondrites are among the least thermally altered samples from the early solar system. Type II chondrules from the CR chondrites formed under highly variable conditions (e.g., precursor composition, redox conditions, cooling rate), with each chondrule recording a distinct igneous history. The opaque minerals within type II chondrules are consistent with formation during chondrule melting and cooling, starting as S- and Ni-rich liquids at 988-1350 degrees C, then cooling to form monosulfide solid solution (mss) that crystallized around olivine/pyroxene phenocrysts. During cooling, Fe,Ni-metal crystallized from the S- and Ni-rich liquid, and upon further cooling mss decomposed into pentlandite and pyrrhotite, with pentlandite exsolving from mss at 400-600 degrees C. The composition, texture, and inferred formation temperature of pentlandite within chondrules studied here is inconsistent with formation via aqueous alteration. However, some opaque minerals (Fe,Ni-metal versus magnetite and panethite) present in type II chondrules are a proxy for the degree of whole-rock aqueous alteration. The texture and composition of sulfide-bearing opaque minerals in Graves Nunataks 06100 and Grosvenor Mountains 03116 suggest that they are the most thermally altered CR chondrites.

We document interspecific differences and intraspecific variability, and propose a revised phylogeny for Cretaceous biserial planktic foraminifera placed within a refined biostratigraphic framework. Taxonomic emendations are proposed for the genera Protoheterohelix Georgescu & Huber, 2009, and Planoheterohelix Georgescu & Huber, 2009, and for the species Pr. washitensis (Tappan, 1940), Pr. obscura Georgescu & Huber, 2009, Pl. moremani (Cushman, 1938), Pl. reussi (Cushman, 1938), and Laeviheterohelix reniformis (Marie, 1941). In addition, a neotype is designated for Pl. globulosa (Ehrenberg, 1840), and Pl. praenuttalli n. sp. is described. Biserial speciation events are recognized in the planktic foraminiferal Rotalipora cushmani Zone (latest Cenomanian), Helvetoglobotruncana helvetica Zone (early Turonian), and at the Helvetoglobotruncana helvetica-Marginotruncana schneegansi zonal boundary (middle Turonian).

Cores and surface samples were collected along a transect southwest from Southwest Pass ( approximately 30-m water depth) to the head of the Mississippi Canyon ( approximately 170-m depth) in 2004, 2005, and 2007 following hurricane, non-hurricane, and Mississippi flood episodes.Discriminant analysis indicates that all unit types are generally distinguishable. Species that contribute most to the discrimination of units are mostly rare, while the species significant in the ANOVA are among the most abundant. Both abundant and rare species were useful for identifying the provenance of hurricane-deposited sediment. Seaward transport of sediment by hurricanes is indicated by the presence of rare marsh taxa (not recorded in non-hurricane units) and increased relative abundance of coastal taxa in the hurricane units. High relative abundances of taxa that are abundant in both the hurricane and non-hurricane units suggest a portion of the hurricane-deposited sediments were also locally derived. In summary, foraminifera can provide information on the provenance of hurricane-deposited sediment soon after deposition, but bioturbation can destroy this signal rapidly.

In practice, diversity metrics are important in setting management and conservation priorities, just as economic indices contribute to global monetary and financial policies. Thus, key challenges for ecologists are to identify new ways to view and summarise patterns in biodiversity and improve on the metrics available for management purposes. In a recent paper on functional diversity patterns in reef fishes [3], we highlighted the potential of new insights gained from functional trait-based approaches to inform marine management, stressing the need to develop and refine biodiversity measures that are linked to ecology (rather than taxonomy). We used a unique, fisheries-independent reef fish identity and abundance dataset, collected using standardised methods from equatorial to high latitude regions all over the world, to provide the first global view of the distribution of individuals amongst species (including a measure of evenness) and functional traits amongst marine communities. A recent paper by Robinson et al. [4] published in Marine Policy criticised the use of our evenness index as a measure of biodiversity, and questioned the use of functional trait-based metrics derived from surveys of standardised areas for decisions relating to broad-scale management of marine systems. In this paper we respond to Robinson et al. and rebut their claims related to sampling bias and broad-scale applicability of trait-based approaches.

AN - 1659768169; 25714606 AB - Studies have identified chemicals within the stony coral genus Montipora that have significant biological activities. For example, Montiporic acids A and B and other compounds have been isolated from the adult tissue and eggs of Montipora spp. and have displayed antimicrobial activity and cytotoxicity in cultured cells. The ecological role of these toxic compounds is currently unclear. This study examines the role these toxins play in reproduction. Toxins were found in the eggs and larvae of the coral Montipora capitata. Releasing these toxins by crushing both the eggs and larvae resulted in irreversible inhibition of photosynthesis in endogenous and exogenous zooxanthellae within minutes. Moreover, these toxins were stable, as frozen storage of eggs and larvae did not affect toxicity. Photosynthetic competency of Porites compressa zooxanthellae treated with either frozen or fresh, crushed eggs was inhibited similarly (P > 0.05, ANCOVA). Addition of toxic eggs plugs to live P. compressa fragments caused complete tissue necrosis under the exposed area on the fragments within 1 week. Small volumes of M. capitata crushed eggs added to sperm suspensions reduced in vitro fertilization success by killing the sperm. After 30 min, untreated sperm maintained 90 ± 1.9% SEM motility while those treated with crushed eggs were rendered immotile, 4 ± 1.4% SEM. Flow cytometry indicated membrane disruption of the immotile sperm. Fertilization success using untreated sperm was 79 ± 4% SEM, whereas the success rate dropped significantly after exposure to the crushed eggs, 1.3 ± 0% SEM. Unlike the eggs and the larvae, M. capitata sperm did not reduce the photosynthetic competency of P. compressa zooxanthellae, suggesting the sperm was nontoxic. The identity of the toxins, cellular mechanism of action, advantage of the toxins for M. capitata and their role on the reef are still unknown.

In this study we gathered data on taxonomy, invasive status, invasion history, geographic distribution, and biological and ecological traits of 1,032 alien plant species occurring on different habitats in Puerto Rico and the Virgin Islands. These data were used to evaluate the relative importance of habitat and species attributes in influencing the likelihood of alien plants to become naturalized and subsequently invasive on these islands. Our results showed that alien species were more likely to become naturalized if they grow in semi-natural habitats, have large native distribution ranges, long residence time, were introduced for horticulture and have mixed breeding systems. On the other hand, naturalized species were more likely to become invasive if they were introduced for horticulture, behave as weeds, have tolerance to different climatic life-zones, thrive in ruderal habitats, have mixed breeding systems with hermaphroditic flowers, reproduce vegetatively and produce small seeds. Whereas some of these parameters were important for both transitions, others were important for either naturalization or invasion. Overall, our results emphasize the importance of studying different stages of the invasion process in order to understand the mechanisms explaining successful invasions rather than baseline approaches of simply comparing invasive with natives or noninvasive alien species. Understanding the process by which alien species become naturalized or invasive could provide a more objective and accurate approach for managing and predicting biological invasions.

Measurements of natural abundance nitrogen isotope ratios (denoted as delta 15N relative to a standard) increasingly serve as integrative proxies for mycorrhiza-mediated N acquisition due to biological fractionation processes that alter 15N:14N ratios. Current understanding of these processes is based on studies from high-latitude ecosystems where plant productivity is largely limited by N availability. Much less is known about the cause and utility of ecosystem delta 15N patterns in the tropics. Using structural equation models, model selection and isotope mass balance we assessed relationships among co-occurring soil, mycorrhizal plants and fungal N pools measured from 40 high- and 9 low-latitude ecosystems. At low latitudes 15N-enrichment caused ecosystem components to significantly deviate from those in higher latitudes. Collectively, delta 15N patterns suggested reduced N-dependency and unique sources of EcM 15N-enrichment under conditions of high N availability typical of the tropics. Understanding the role of mycorrhizae in global N cycles will require reevaluation of high-latitude perspectives on fractionation sources that structure ecosystem delta 15N patterns, as well as better integration of EcM function with biogeochemical theories pertaining to climate-nutrient cycling relationships.

We identified 295 individuals using photo-identification of dorsal fins, including 58 calves, and the population estimate for a single season was 100-300 solitary adults plus 25-50 mothers with calves; the estimated population of animals across all seasons using a mark and recapture model was over 1,000. Eight of the 139 fluke identifications were matched to whales in photograph catalogues from the Antarctic Peninsula and a ninth was matched to a whale sighted in Chilean waters; four of these nine individuals have also been sighted in Colombia. We conclude that Panama (Las Perlas Archipelago in particular) is an important calving area for humpback whales in the Southern Hemisphere. These data should provide a foundation for monitoring of population change and to increase awareness in Panama about the need to manage vessel traffic and tourism related to the whales at Las Perlas.

AN - 1645777494; 25569806 AB - Model genetic systems are invaluable, but limit us to understanding only a few organisms in detail, missing the variations in biological processes that are performed by related organisms. One such diverse process is the formation of magnetosome organelles by magnetotactic bacteria. Studies of model magnetotactic α-proteobacteria have demonstrated that magnetosomes are cubo-octahedral magnetite crystals that are synthesized within pre-existing membrane compartments derived from the inner membrane and orchestrated by a specific set of genes encoded within a genomic island. However, this model cannot explain all magnetosome formation, which is phenotypically and genetically diverse. For example, Desulfovibrio magneticus RS-1, a δ-proteobacterium for which we lack genetic tools, produces tooth-shaped magnetite crystals that may or may not be encased by a membrane with a magnetosome gene island that diverges significantly from those of the α-proteobacteria. To probe the functional diversity of magnetosome formation, we used modern sequencing technology to identify hits in RS-1 mutated with UV or chemical mutagens. We isolated and characterized mutant alleles of 10 magnetosome genes in RS-1, 7 of which are not found in the α-proteobacterial models. These findings have implications for our understanding of magnetosome formation in general and demonstrate the feasibility of applying a modern genetic approach to an organism for which classic genetic tools are not available.

Coastal USA, excluding Alaska and Hawaii Using a Monte Carlo simulation approach, we predicted changes in discharged ballast water, wetted surface area of ship hulls and frequency of ship arrivals modelled under scenarios that are based on (1) current shipping patterns from the western Pacific Rim to the USA, (2) estimates of fleet expansion and (3) diversion of traffic away from the US West Coast through the Panama Canal. During the 5-year period following canal expansion (2015-2019), our models estimated that the Gulf and East coasts would receive 78% and 99% median increases in total ballast discharge and 172% and 182% increases in total wetted surface area, respectively. For the West Coast, our models estimated 9.6% median decreases in both total ballast discharge and wetted surface area. We further predict that many ports in the Gulf and East coasts will receive up to three times the current number of arrivals and increased ballast water discharge, from this region after expansion. Our scenario-based analysis provides a first estimate for increases in frequency, magnitude and spatial distribution of exposure that the Gulf and East coasts will experience due to ships and ballast arriving from the western Pacific, following the canal expansion. If organisms transported via ballast water or ship hulls are able to survive transit of the canal, the predictions suggest increased likelihood of introduction along these coasts by species originating in the western Pacific.

analysis of the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database AN - 1861090804; 690602-7 AB - The Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database contains data on 1,883 Quaternary eruption records of magnitude (M) 4 and above and is publically accessible online via the British Geological Survey. Spatial and temporal analysis of the data indicates that the record is incomplete and is thus biased. The recorded distribution of volcanoes is variable on a global scale, with three-quarters of all volcanoes with M> or =4 Quaternary activity located in the northern hemisphere and a quarter within Japan alone. The distribution of recorded eruptions does not strictly follow the spatial distribution of volcanoes and has distinct intra-regional variability, with about 40% of all recorded eruptions having occurred in Japan, reflecting in part the country's efforts devoted to comprehensive volcanic studies. The number of eruptions in LaMEVE decreases with increasing age, exemplified by the recording of 50% of all known Quaternary eruptions during the last 20,000 years. Historical dating is prevalent from 1450 AD to the present day, substantially improving record completeness. The completeness of the record also improves as magnitude increases. This is demonstrated by the calculation of the median time, T (sub 50) , for eruptions within given magnitude intervals, where 50% of eruptions are older than T (sub 50) : T (sub 50) ranges from 5,070 years for M4-4.9 eruptions to 935,000 years for M> or =8 eruptions. T (sub 50) follows a power law fit, suggesting a quantifiable relationship between eruption size and preservation potential of eruptive products. Several geographic regions have T (sub 50) ages of <250 years for the smallest ( nearly equal M4) eruptions reflecting substantial levels of under-recording. There is evidence for latitudinal variation in eruptive activity, possibly due to the effects of glaciation. A peak in recorded activity is identified at 11 to 9 ka in high-latitude glaciated regions. This is absent in non-glaciated regions, supporting the hypothesis of increased volcanism due to ice unloading around this time. Record completeness and consequent interpretation of record limitations are important in understanding volcanism on global to local scales and must be considered during rigorous volcanic hazard and risk assessments. The study also indicates that there need to be improvements in the quality of data, including assessment of uncertainties in volume estimates.

Here, we consider planets cast out to large orbital distances on eccentric, bound orbits through a gaseous disk. With simple numerical models, we show that super-Earths can interact with the gas through dynamical friction to settle in the remote outer regions of a planetary system. Outcomes depend on planet mass, the initial scattered orbit, and the evolution of the time-dependent disk. Efficient orbital damping by dynamical friction requires planets at least as massive as the Earth. More massive, longer-lived disks damp eccentricities more efficiently than less massive, short-lived ones. Transition disks with an expanding inner cavity can circularize orbits at larger distances than disks that experience a global (homologous) decay in surface density. Thus, orbits of remote planets may reveal the evolutionary history of their primordial gas disks. A remote planet with an orbital distance approximately 100 AU from the Sun is plausible and might explain correlations in the orbital parameters of several distant trans-Neptunian objects.

We explore the nature of this record in terms of what is preserved, where, why and with what biases. And as a consequence, how it can be used to answer questions posed at various spatial and temporal scales, what cautions we must consider when interpreting it, and what surprises it may hold. Generally speaking, the record of terrestrial plants is rich and reveals clear directional trends in phenotypic complexity, biodiversity, and ecosystem organization. It also has reasonably well understood taphonomic biases. It must be used with considerable caution, however, when researching time and location of evolutionary innovations and the development of ecological structure and interactions.

We develop a model that generates updated spectra of solar wind charge-exchange emissions together with accurate scattering and fluorescence spectra of solar X-rays by atoms, molecules, and ice/dust particles. Our model also explores scattering and fluorescence spectra for different solar conditions, including spectra induced by solar X-ray flares of different classes and durations. Utilizing our results, the major emission mechanism is determined for both the 0.3-1.0 keV and 1.0-3.0 keV photon energy ranges. Additionally, we compare the modeled spectra of cometary X-rays with cometary observations from the Chandra X-Ray Observatory. These comparisons establish upper limits on ice/dust mass production rates, with an emphasis on nanoparticles, for several comets. We conclude with a discussion of the impact of of ice/dust particles in the formation of cometary X-ray emission spectra.

Mutual gravitational interactions between the two planets perturb the planets' transit times, allowing the planets' masses to be measured. Despite the similarity of their masses and orbital radii, the planets show a stark contrast in their mean densities; the inner planet (Kepler-36 b) is more than eight times as dense as its outer companion planet (Kepler-36 c). We perform a photo-dynamical analysis of the Kepler-36 system based on more than three years of Kepler photometry. With N-body integrations of initial conditions sampled from the photo-dynamical fits, we further refine the properties of the system by ruling out solutions that show large scale instability within 5 Giga-days. Ultimately, we measure the planets' masses within 4.2% precision, and the planets' radii with 1.8% precision. Kepler-36 b is currently the rocky exoplanet with the most precisely measured mass and radius. Kepler-36 b's mass and radius are consistent with a earth-like composition, and an iron-enhanced Mercury-like composition is ruled out.

Constraining the source, magnitude, timing and duration of FSVs will provide insight into the mechanism and extent of fluvial activity on Mars and the geologic and climatic environments in which they formed. Unlike the older Noachian-Hesperian valleys that are characterized by integrated, dissected and degraded networks that cover large spatial extents, FSVs are typically narrow, short or discontinuous valleys with low drainage densities. They are generally incised no more than a few decameters, slightly degraded at multi-meter scales, and cluster in the mid-latitudes (35-50 degrees in both hemispheres). A high concentration of FSVs occurs in northern Arabia Terra ( approximately 33 degrees N, 8 degrees E), a Noachian-aged landscape characterized by broad, irregular depressions. Many of the FSVs in this region are 150+ km long and some appear to cross depressions that were likely filled with ice or water at the time of formation. Examples of broad, flat floored FSVs with incised channels could either indicate a complex history of a single flow event or multiple flow events. The occurrence of "pollywogs," fairly fresh, small (typically 2-10 km in diameter) craters with a single channel extending from the rim outward, implies overflow of the crater, the presence of a deep lake and the involvement of artesian groundwater flow. Roughly 25% of the FSVs in our northern Arabia Terra study region occur on relatively fresh crater ejecta, which may be related to formation age, topography, surface materials and (or) substrate. Ejecta with dense concentrations of FSVs average 25.5 km in diameter, have more degraded crater interiors, and well developed petal-like ejecta. Ejecta with sparse or no FSVs have radial ejecta with less distinct petals and are associated with smaller craters (16 km and 8 km in diameter, respectively) that have less degraded crater interiors. Crater statistics suggest ejecta with high concentrations of FSVs are relatively older than ejecta with sparse or no FSVs. The crater statistics also suggest the valleys formed in the mid-Hesperian to early Amazonian, coeval with the formation of large alluvial fans.

Whipple will reach much deeper into the unexplored frontier of the outer solar system than any other mission, current or proposed. Whipple will look back to the dawn of the solar system by discovering its most remote bodies where primordial processes left their imprint. Specifically, Whipple will monitor large numbers of stars at high cadences ( approximately 12,000 stars at 20 Hz to examine Kuiper Belt events; as many as approximately 36,000 stars at 5 Hz to explore deep into the Oort Cloud, where events are less frequent). Analysis of the detected events will allow us to determine the size spectrum of bodies in the Kuiper Belt with radii as small as approximately 1 km. This will allow the testing of models of the growth and later collisional erosion of planetesimals in the early solar system. Whipple will explore the Oort Cloud, detecting objects as far out as approximately 10,000 AU. This will be the first direct exploration of the Oort Cloud since the original hypothesis of 1950. Whipple is a Discovery class mission that will be proposed to NASA in response to the 2014 Announcement of Opportunity. The mission is being developed jointly by the Smithsonian Astrophysical Observatory, Jet Propulsion Laboratories, and Ball Aerospace & Technologies, with telescope optics from L-3 Integrated Optical Systems.

The crater is Noachian in age, complex in morphology, and largely buried by younger sulfate-rich rocks. Nevertheless, exposed rim segments dubbed Cape York (CY) and Solander Point/Murray Ridge (S/M) approximately 1500 m to the south reveal breccias interpreted as remnants of the ejecta deposit (Shoemaker Formation or SF) that at CY overlie the pre-impact country rocks (Matijevic Formation or MF). At CY, relief is approximately 10 m and consists of 6-7 m of SF over at least several m of MF. By contrast, the MF/SF contact is not visible at S/M despite outcrops some 20 m below and 60 m above the elevation of the contact at CY. This implies some structural offset between the rim segments and suggests up to 70 m section is preserved at S/M. The lack of information about the orientation of the SF at S/M makes the true thickness difficult to establish, though it appears to be 10's of m more than at CY. Comparison to similar sized, fresh, complex craters on Mars and the Moon suggests there was originally 100-200 m of ejecta at Endeavour's rim. Ejecta comprise only 20-25% of the rim relief around lunar craters of similar size, thereby implying an original rim height of up to 500-1000 m at Endeavour. If accurate, then approximately 400-800 m of the rim remains buried; the higher end of this range is close to the 800-900 m section interpreted elsewhere. If 200 m ejecta were present, then CY and S/M experienced approximately 190 m and over 100 m erosional lowering, respectively. If 100 m ejecta were present then rim lowering was approximately 90 m and 10's of m, respectively. Such differences between rim segments likely relate to changing efficiency of responsible processes and/or varying characteristics of the rocks and indicate portions of Endeavour crater experienced significant degradation. A paucity of exposed debris shed from SF and MT around the CY and S/M rim segments relegates most erosion to before the surrounding plains deposits were emplaced. Endeavour ranges between 250-500 m deep. By contrast, recent studies of pristine complex craters on Mars suggest the original depth was probably closer to 2000 m, though it is unclear how much older fill may occur beneath exposed sulfate-rich rocks.

MOC revealed outcrops of an interbedded ice and dark-sand "basal unit" (BU) below steep NPLD scarps. Some bright markings on the BU were suggested to be talus deposits of mass-wasted NPLD ice, caused by undercutting via removal of easily erodible BU sand. In previous work with HiRISE images that confirmed the origin of these deposits, we: detailed their meter-scale morphology, constituent features, and variability; identified fractures of BU ice layers and NPLD scarps as additional mass-wasting facilitators; and, based on inter- and inter-annual monitoring, discovered that new deposits appear over time, thereby establishing mass wasting (of both BU and NPLD ice) as a currently active process. Here, we advance from qualitative descriptions of new, active processes to quantification of the rates at which they are occurring. From approximately 4 years of HiRISE observations, we cataloged the location, volume, source, and timing constraints of >160 landslide events along approximately 20 km of BU-NPLD scarp. Average rates are approximately 44 events/yr and approximately 2000 m3/yr, although 7 large events account for approximately 3/4 of the volume; this is a very geologically dynamic environment. BU events are more frequent and smaller than NPLD events, reflecting the relative thickness of ice source deposits but also perhaps differing proportions of two causal mechanisms: sand-removal undercutting and thermal-stress induced expansion, contraction, and fracturing. BU events prefer summer over spring; NPLD events strongly prefer fall-winter over spring-summer. We compare this observational data with 1) thermal stress models of the ice scarp to assess consistency in timing of activity, and 2) sublimation models of the ice scarp to assess the relative contributions to scarp retreat--our preliminary mass-wasting estimate is approximately 2.5 mm/yr. The value in developing such rate estimates is the potential to consider time scales in exploring aspects of large-scale north polar landscape evolution (e.g., retreating cap edges, the growth of proto-Chasma Boreale, etc.) and the release of water to the atmosphere.

VERITAS addresses the highest priority Decadal survey questions: 1) Did Venus host ancient aqueous environments? 2) Can understanding the roles of physics, chemistry, geology, and dynamics in driving planetary atmospheres lead to a better understanding of climate change on Earth? 3) How have chemical and physical processes operated, interacted, and evolved? Using an interferometric mapping radar, a near infrared spectrometer, and radio science experiment, VERITAS will examine 1) the similarity of tessera plateau formation to continents on Earth, 2) the current forces driving tectonics and volcanism, and, perhaps most importantly, 3) inform our understanding of how stagnant lid planets evolve. Data from VIRTIS on Venus Express show that the highly deformed tessera plateaus, possible remnants of a prior regime on Venus, may be more felsic in composition than the surrounding plains, supporting the hypothesis they are similar to Earth's continents. However this interpretation is equivocal due to uncertainty in the available altimetry. VERITAS is designed to collect data with sufficient resolution to answer this question definitively, and also aid in the assessment of tesserae as a touchdown point for a future lander. Similarly, the enormous rift zones and mountain belts are manifestations of global scale tectonics within the last billion years on Venus, but present data are not adequate to determine the driving forces or whether they are presently active. VERITAS will provide such data through fine-resolution topographic maps and, if possible, measurements of any current-day crustal deformation. Finally, current data are highly suggestive of recent and active volcanism. VERITAS observations can tell us if current volcanism is limited to mantle plume heads or is more widespread. The geologic setting of present day volcanism or tectonism also holds lessons for predicting activity on Earth-sized planets elsewhere in the galaxy. Together these investigations allow us to assess just how similar or dissimilar the evolution of Venus and Earth has been.

In images obtained at spatial scales as good as approximately 3 m/pixel, small thrust-fault scarps have been detected. The small scarps found thus far are less than 10 km in length and have only tens of meters of relief, much smaller than the large lobate scarps that are the dominant contractional tectonic landform on Mercury and have been attributed to cooling and contraction of the planetary interior. The small scarps on Mercury are nonetheless comparable in scale to similar small scarps documented on the Moon. High-resolution MESSENGER images also reveal that the small scarps crosscut small impact craters (<100 m in diameter). Transected small craters <100 m in diameter on the Moon are Copernican (< approximately 800 My) in age, broadly equivalent to the Kuiperian period on Mercury. Their low relief, lack of superposed small craters, and pristine appearance support the inference that these scarps are geologically young, because small landforms on Mercury will not survive for billions of years under steady meteoroid bombardment. Lunar lobate scarps comparable in scale could be less than 50 My old on the basis of estimated rates of infilling of small, shallow graben in the back-scarp terrain. The impact flux on Mercury is estimated to be a factor of approximately 3 greater than on the Moon, so the rate of degradation of small landforms on Mercury is expected to be comparably greater. In addition to the detection of small, young scarps, MESSENGER is acquiring images of large lobate scarps from low altitudes. Disturbed and crosscut small impact craters (<100 m in diameter) have been found in high-resolution images on the northwest segment of Carnegie Rupes, indicating recent activity on thrust-fault segments associated with older, prominent scarps. The young, small fault scarps and small-diameter craters crosscut by both small and large scarps are evidence that the contraction of Mercury has continued to geologically recent time and is likely ongoing.

We explore the relationship in the northern hemisphere between locations of lobate scarps and high-relief ridges >50 km in length and inferred crustal thickness to understand whether mechanisms that result in crustal thickening and thinning may have also influenced the locations of large thrust faults. These landforms are concentrated in areas with >53 km crustal thickness (at the 99% confidence level, on the basis of a two-sided single proportion test), an extreme end of the normal distribution (with a mean of 40 km) of modeled crustal thickness values. One possible mechanism for thickening crust and concentrating prominent thrust faults is mantle flow; a broad pattern of mantle upwelling and downwelling is compatible with Mercury's gravity anomaly and topography fields at long (>1000 km) horizontal wavelengths. On Earth (e.g., central Australia), midplate mantle downwelling has been invoked as a mechanism to thicken overlying continental crust and increase compressional stresses in the rigid upper portion of the lithosphere. Downwelling in some areas requires upwelling in others; horizontal divergence could decrease levels of compressive stresses over upwelling regions and might account for the deficiency of large thrust faults in areas of thinnest crust (<27 km, significant at the 95% confidence level). We tested the possibility that this deficiency instead corresponds to burial by thick volcanic flows within areas of smooth plains by excluding the northern plains and Caloris interior plains (the two largest expanses of smooth plains), but there was no significant change from the result for the full hemisphere. If mantle flow contributed to the current patterns of crustal thickness and large thrust fault locations, an implication is that either (i) the large-scale pattern of mantle flow on Mercury was long-lasting and geographically stationary during the period when the planet contracted, or (ii) a shorter episode of mantle flow coincided with the development of many scarps, perhaps because of a relatively high rate of contraction at that time.

A fundamental physical characteristic is particle shape, which is diagnostic of transport process as well as the distance traveled. For example, it is possible to distinguish the emplacement process of sediments based entirely on the shape of the quartz grains in the deposit [e.g., Folk, 1980]. Such basic sedimentological concepts have been applied to our interpretation of surface materials on the terrestrial planets [e.g. Cabrol et al., 2014]. However, what we know about the nature of sedimentary materials is based primarily on sediments that have weathered from felsic rocks-granite. This is true because felsic materials compose most of the landmass on the Earth. Yet, the surface of Mars is composed predominately of mafic materials-basalt-and sedimentary particles derived from basalt are much different than those derived from granite. Instead of quartz, feldspar, and heavy minerals commonly found in most terrestrial sedimentary deposits, basaltic sediments are typically composed of varying amounts of olivine, pyroxene, plagioclase, and vitric and lithic fragments. Both the persistence of basaltic particles and their specific gravities are different than particles derived from granite. These differences are important because they will affect the characteristics of basaltic sediment as it is transported by wind, water, and ice, and currently we have little to no understanding as to how basaltic sediment will weather as a function of the transport mechanism and distance. We will present preliminary analyses of typical basaltic sediments that have been transported by a variety of geologic processes in Hawaii, including details about surface texture, componentry, and the influence different sedimentary processes may have on remote sensing data. The figure below shows examples of A) sediment transported by fluvial processes, B) sediment collected from the surface of a large climbing dune, and C) sediment collected from an end moraine located at the summit of Mauna Kea.

Overlying the pre-impact lithologies and rim breccias is a thin apron of fine-grained sediments, the Grasberg fm, forming annuli on the lower slopes of rim segments. Hesperian Burns fm sandstones overly the Grasberg fm. Grasberg rocks have major element compositions that are distinct from Burns fm sandstones, especially when comparing interior compositions exposed by the Rock Abrasion Tool. Grasberg rocks are also different from Endeavour rim breccias, but have general compositional similarities to them. Grasberg sediments are plausibly fine-grained materials derived from the impact breccias. Veins of CaSO (sub 4) transect Grasberg fm rocks demonstrating post-formation aqueous alteration. Minor/trace elements show variations consistent with mobilization by aqueous fluids. Grasberg fm rocks have low Mn and high Fe/Mn ratios compared to the other lithologies. Manganese likely was mobilized and removed from the Grasberg host rock by redox reactions. We posit that Fe (super 2+) from acidic solutions associated with formation of the Burns sulfate-rich sandstones acted as an electron donor to reduce more oxidized Mn to Mn (super 2+) . The Fe contents of Grasberg rocks are slightly higher than in other rocks suggesting precipitation of Fe phases in Grasberg materials. Pancam spectra show that Grasberg rocks have a higher fraction of ferric oxide minerals than other Endeavour rim rocks. Solutions transported Mn (super 2+) into the Endeavour rim materials and oxidized and/or precipitated it in them. Grasberg has higher contents of the mobile elements K, Zn, Cl, and Br compared to the rim materials. Similar enrichments of mobile elements were measured by the Spirit APXS on West Spur and around Home Plate in Gusev crater. Enhancements in these elements are attributed to interactions of hydrothermal acidic fluids with the host rocks. Interactions of fluids with the Grasberg fm postdate the genesis of the Endeavour rim phyllosilicates. The aqueous alteration history of Endeavour rim rocks is complicated by different styles of alteration that have spanned the Noachian and Hesperian. Late stage acidic aqueous alteration of Grasberg fm materials is likely penecontemporaneous with the diagenesis of the sulfate-rich sediments of Meridiani Planum.

Near-surface f (sub O2) recorded by primitive MORB glasses and abyssal peridotites anchor the f (sub O2) profile of the mantle at depth. If the f (sub O2) -depth relationship of the mantle is known, then the depth of the DCO3 can be predicted. Alternatively, if the DCO3 can be detected geophysically, then its depth can be used to infer physical and chemical characteristics of upwelling mantle. We present an expanded version of a model of the f (sub O2) -depth profile of adiabatically upwelling mantle first presented by Stagno et al. (2013), kindly provided by D. Frost. The model uses a chemical mass balance and empirical fits to experimental data to calculate compositions and modes of mantle minerals at specified P, T, and bulk Fe (super 3+) /Sigma Fe. We added P and T dependences to the partitioning of Al and Ca to better simulate the mineralogical changes in peridotite at depth and included majorite component in garnet to increase the depth range of the model. We calculate f (sub O2) from the mineral assemblages using the grt-ol-opx oxybarometer (Stagno et al., 2013). The onset of carbonated melting occurs at the intersection of a Fe (super 3+) /Sigma Fe isopleth with the DCO3. Upwelling mantle is tied to the DCO3 until all native C is oxidized to form carbonated melts by reduction of Fe (super 3+) to Fe (super 2+) . The depth of intersection of a parcel of mantle with the DCO3 is a function of bulk Fe (super 3+) /Sigma Fe, potential temperature, and bulk composition. We predict that fertile mantle (PUM) along a 1400 degrees C adiabat, with 50 ppm bulk C, and Fe (super 3+) /Sigma Fe = 0.05 after C oxidation begins redox melting at a depth of 250 km. The model contextualizes observations of MORB redox chemistry. Because fertile peridotite is richer in Al (sub 2) O (sub 3) , the Fe (sub 2) O (sub 3) -bearing components of garnet are diluted leading to lower f (sub O2) at a given depth compared to refractory mantle under the same conditions. This may indicate that the negative correlation observed between enrichment and f (sub O2) at ridges (Cottrell and Kelley, 2013) is a consequence of the increased fertility of remixing recycled crust into the mantle. Addition of reduced C to the mantle during subduction can also explain this observation. Geophysical detection of the depth of the DCO3 may resolve these hypotheses.

Thus, it is important to understand how fO (sub 2) changes during a peridotite's thermal and petrologic history in the asthenospheric and lithospheric mantle, as metamorphic subsolidus reequilibration can result in changes to recorded fO (sub 2) . A case study of Tongan forearc peridotites highlights the heterogeneity seen in mantle peridotites. We analyzed two dredges located 250 km apart along the trench: one dredge ranges in fO (sub 2) from 0.5 to 1 log unit above the QFM buffer, similar to analyses of supra-subduction zone xenoliths (e.g. Brandon and Draper, 1996; Wood and Virgo, 1989) while the other dredge ranges from QFM-0.75 to QFM+0.25 and exhibits high spinel Cr# (ranging from 0.45 to 0.75). Systematics between fO (sub 2) , Ti concentration, olivine forsterite content, and Cr# within each dredge allow us to differentiate between the effects of melt extraction, melt interaction, and cooling. Because the spinel oxybarometry equation is dependent on temperature, it is important to be able to accurately determine the temperature recorded by peridotites. Though many geothermometers are available for mantle rocks, we assert that geothermometers based on Fe-Mg exchange between olivine and spinel are the most applicable to fO (sub 2) calculations, because the oxygen fugacity recorded by a mantle assemblage is primarily controlled by this exchange. Additionally, preliminary analyses of diffusion profiles across olivine-spinel grain boundaries provide insight into the cooling of peridotite in the oceanic lithosphere and its effects on oxygen fugacity. Mg-Fe exchange between olivine and spinel is controlled by the distribution coefficient, KD, which is dependent on both temperature and the proportion of Cr to other trivalent cations in spinel. We see an increase in olivine forsterite content towards the olivine-spinel interface, consistent with an increase in KD as cooling occurs. Limited data indicate that while spinel Cr# decreases as the interface is approached, no change is seen in spinel Fe (super 3+) /Sigma Fe ratios. As a result, the increased Fo# in olivine dominates the oxybarometry equation, resulting in higher oxygen fugacity values near the interface as cooling occurs.

Efficient radial transport of angular momentum in the protoplanetary disk, an essential requirement for the formation of stars and planets, may be mediated by the magneto-rotational instability (MRI) or magnetocentrifugal winds (MCW). Magnetic fields may also generate turbulence in the nebular gas, potentially leading to instabilities that created the first planetesimals. Finally, magnetic reconnection events may lead to the formation of chondrules, which are millimeter-sized meteoritic inclusions that likely constituted a major building block of terrestrial planets in the solar system. Direct measurements of the magnetic field in the planet-forming region of a protoplanetary disk, which have remained hitherto elusive to astronomical observations, are necessary to test the theoretical models discussed above. Because chondrules were heated and cooled in the nebula, they potentially carry a record of nebular magnetic fields. Newly developed microsampling and magnetic field mapping techniques based on the SQUID microscope can measure very weak moments (<10-13 Am2) from oriented small ( approximately 100 mu m) samples, enabling the recovery of detailed paleomagnetic data from single chondrules. We performed paleomagnetic experiments on 13 chondrules from the primitive LL3.0 chondrite Semarkona. We showed that dusty olivine-bearing chondrules (Fig. 1) were magnetized prior to the assembly of the meteorite in a magnetic field of 54+ or -21 mu T. This field strength provides evidence against chondrule formation near the sun as predicted by the x-wind model while favoring weak-field processes such as nebular shocks or planetesimal collisions. Furthermore, such fields are sufficient to redistribute angular momentum efficiently via either the MRI or MCW, strongly suggesting that magnetic fields are the primary driver of mass accretion in protoplanetary disks. Ongoing paleomagnetic work focuses on other chondrite classes, potentially constraining magnetic fields for a range of ages and locations in the protoplanetary disk. Together, these efforts highlight the promise of new techniques to expand the relevance of paleomagnetism to non-planetary fields and astrophysical questions.

Cross-disciplinary investigations would greatly benefit from near real-time data access and visualization within the existing framework of databases and GIS tools. An example of complex, interdisciplinary field-based and data intensive investigations is that of volcanologists and gas geochemists, who sample gases from fumaroles, hot springs, dry gas vents, hydrothermal vents and wells. Compositions of volcanic gas plumes are measured directly or by remote sensing. Soil gas fluxes from volcanic areas are measured by accumulation chamber and involve hundreds of measurements to calculate the total emission of a region. Many investigators also collect rock samples from recent or ancient volcanic eruptions. Structural, geochronological, and geophysical data collected during the same or related field campaigns complement these emissions data. All samples and data collected in the field require a set of metadata including date, time, location, sample or measurement id, and descriptive comments. Currently, most of these metadata are written in field notebooks and later transferred into a digital format. Final results such as laboratory analyses of samples and calculated flux data are tabulated for plotting, correlation with other types of data, modeling and finally publication and presentation. Data handling, organization and interpretation could be greatly streamlined by using digital tools available in the field to record metadata, assign an International Geo Sample Number (IGSN), upload measurements directly from field instruments, and arrange sample curation. Available data display tools such as GeoMapApp and existing data sets (PetDB, IRIS, UNAVCO) could be integrated to direct locations for additional measurements during a field campaign. Nearly live display of sampling locations, pictures, and comments could be used as an educational and outreach tool during sampling expeditions. Achieving these goals requires the integration of existing online data resources, with common access through a dedicated Web portal.

These protons are produced by nuclear spallation, a consequence of galactic cosmic ray (GCR) bombardment of the lunar regolith. Just as spalled neutrons and gamma rays reveal elemental abundances in the lunar regolith, albedo protons may be a complimentary method for mapping compositional variations. We presently find that the lunar maria have an average proton yield 0.9% + or -0.3% higher than the average yield in the highlands; this is consistent with neutron data that is sensitive to the regolith's average atomic weight. We also see cases where two or more adjacent pixels (15 degrees X 15 degrees ) have significantly anomalous yields above or below the mean. These include two high-yielding regions in the maria, and three low-yielding regions in the far-side highlands. Some of the regions could be artifacts of Poisson noise, but for completeness we consider possible effects from compositional anomalies in the lunar regolith, including pyroclastic flows, antipodes of fresh craters, and so-called "red spots". We also consider man-made landers and crash sites that may have brought elements not normally found in the lunar regolith.

Several studies have used the spinel peridotite oxybarometer to estimate f (sub O2) ; yet few data exist from ocean islands, despite the importance of f (sub O2) to understanding ocean island basalt petrogenesis (Herzberg and Asimow, 2008). We report f (sub O2) recorded by peridotite xenoliths from three ocean islands: Savai'i (average f (sub O2) = QFM -1.4 to +0.9), Tahiti (QFM +0.6 to +0.7) and Tubuai (QFM -1.1 to +0.2). We calculate f (sub O2) using methods and standards from Wood and Virgo (1989) and Wood (RiMG, 1990). Oxygen fugacities span a similar range to those reported for El Hierro, Oahu, and Tahiti by Ballhaus (1993): more reduced than arc peridotites, but more oxidized than abyssal peridotites. Spinels in several of the xenoliths are heterogeneous and record a range of apparent f (sub O2) at the mm scale. We propose two distinct mechanisms for introducing f (sub O2) heterogeneity: melt refertilization (Tubuai) and diffusive reequilibration (Savai'i and Tubuai). Spinels in one Tubuai sample record increasing f (sub O2) from QFM-0.6 in the xenolith interior to +1.1 at the basalt interface. Apparent f (sub O2) recorded by these spinels correlate with TiO (sub 2) , an indicator of melt refertilization (Pearce et al., 2000). We suggest that spinels from the xenolith interior record the relatively low f (sub O2) conditions of the lithospheric mantle, while host basalt has oxidized near-interface spinels. Uniformly high TiO (sub 2) , f (sub O2) , and low olivine Mg# in Tahitian xenoliths from this study may indicate that refertilization has reset the f (sub O2) recorded by these rocks. Closed-system diffusive reequilibration, caused by changes in temperature, can also change the f (sub O2) recorded by a peridotite. In samples from Savai'i and Tubuai with multiple spinel habits, fine intergrowth spinels and the rims of large, equant spinels record higher apparent f (sub O2) and lower Al (sub 2) O (sub 3) than cores of large grains. Canil and O'Neill (1996) suggest that the MgAl (sub 2) O (sub 4) component in spinel dissolves into pyroxenes as a function of increasing temperature, leaving a lower modal proportion of Fe (super 3+) -rich spinel. Because we find no evidence for melt refertilization, we suggest that thermal interaction with a plume caused subsolidus, partial reequilibration that increased the f (sub O2) recorded by these peridotites prior to eruption.

Here we report on the physical properties of impact ejecta from Earth-based and orbital radar (Arecibo/Green Bank telescopes at 12.6- and 70-cm wavelengths, and the Lunar Reconnaissance Orbiter Mini-RF) and LRO Diviner thermal infrared observations. Diviner thermal IR data provide estimates of surface rock abundance, and the radar datasets reveal rocks buried beneath up to several meters of regolith. These four datasets represent a spectrum of observational wavelengths, and their intercomparison provides a means of constraining both ejecta block content and depth extent. We examine all craters on the lunar nearside that show evidence for blocky ejecta, whether buried or on the surface, in order to investigate spatial, crater size-, and time-dependent variations in ejecta block size distribution and spatial extent. Previous work has shown that it is possible to quantify the relationship between surface ejecta rock content and crater age for craters younger than approximately 1 Gyr; we will now present the results of our effort to extend the age range over which this relationship can be applied by investigating buried ejecta as well. Further, we report on the thermophysical characteristics of distal fine-grained ejecta that have previously been shown to exhibit unique radar characteristics (low radar return and circular polarization ratio). Our results constrain the physical properties of ejecta, and variations in those properties with time and depth, to an extent not possible from examination of visible-wavelength images and multispectral data alone.

Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) high resolution (50-200 cm/pixel) images enable the detailed study of lunar tectonic landforms and further insight into the evolution of stresses. Populations of landforms are now observed at scales much smaller than previously recognized, and their morphology and stratigraphic relationships imply a complex deformational history. The most common tectonic landforms in mare basins are sinuous wrinkle ridges that have up to hundreds of meters of relief and are interpreted as folded basalt layers overlying thrust faults. They consist of a narrow, asymmetric ridge atop a broad arch and sometimes occur radial to or concentric with the centers of some mare basins. Wrinkle ridges with these patterns have previously been associated with mascons--dense concentrations of mass identified by positive gravity anomalies. Loading of the crust by lunar mascons causes flexure and subsidence to form wrinkle ridges. However, some basins including western Mare Frigoris are not associated with mascons, yet wrinkle ridges deform the mare. The origin of compressional stresses in non-mascon environments remains an outstanding question. A key step to better understanding the occurrence of wrinkle ridges in non-mascon basins is characterizing the behavior of the underlying faults. We expand upon methods used in Williams et al. [2013] and apply fault dislocation modeling to estimate geometries and displacements for selected wrinkle ridge faults in Mare Frigoris. Digital terrain models (DTMs) derived from LROC NAC stereo pairs are used to constrain fault models. Using the system of analytical equations for deformation of a half-space defined by Okada [1985, 1992], we apply inverse methods to model ridge relief for fault geometry. Preliminary results suggest maximum depths of faulting within the upper approximately 1-2 km and shallow (<40 degrees ) dip angles. These preliminary modeled values are comparable to estimates for other lunar and Martian wrinkle ridges, and suggest this faulting is likely confined to within the mare fill and not rooted deeply in anorthositic crust.

We use a combination of remote sensing data from ground-based radar observations (Arecibo and Green Bank Telescope at wavelengths of 12.6 cm and 70 cm) and the Lunar Reconnaissance Orbiter spacecraft (Diviner, Mini-RF) to determine how the regolith structure varies across volcanic terrains and possible future landing sites. Radar can detect buried units and provide a measure of roughness, while thermal infrared data provides complimentary information on the surface and near-surface rock abundance in the upper centimeters. Radar and infrared wavelengths are also sensitive to different sized rocks, which can be used to determine where there are increased numbers centimeter-sized rocks. A comparison of these data sets reveals significant differences in regolith stratigraphy across targets. For example, small rilles on the Aristarchus Plateau to the northeast of the Constellation Aristarchus 2 site are surrounded by rock-poor deposits and are likely a secondary source of pyroclastic materials. Some rilles, such as Rima Birt, are surrounded by pyroclastics that change in depth and/or embedded rock abundance along the length of the rille. We will present results from our data analysis and subsequent mapping, focusing on rilles, pyroclastic deposits, and Constellation Region of Interest targets including the Apollo sites.

Melt inclusions were analyzed for volatile contents using two different techniques, Fourier Transform Infrared Spectroscopy (FTIR) and ion microprobe (SIMS). Data from FTIR on quartz-hosted melt inclusions reveal pre-eruptive CO (sub 2) concentrations (maximum nearly equal 300 ppm), and H (sub 2) O contents (average = 4.3 wt.%) that are similar to H (sub 2) O contents derived from SIMS on the same inclusions (average = 4.2 wt.%). Melt inclusions in sanidine yield higher CO (sub 2) concentrations (maximum nearly equal 400 ppm) than those hosted in quartz, yet yield much lower H (sub 2) O contents (average = 2.5 wt.% via FTIR; average = 2.7 wt.% via SIMS). The higher CO (sub 2) trapped in sanidine-hosted melt inclusions may suggest higher trapping pressures than are recorded by quartz, whereas the low H (sub 2) O recorded by sanidine may signify preferential H loss from sanidine. SIMS and Laser-Ablation ICP-MS (LA-ICP-MS) trace element analyses of melt inclusions define a continuous liquid line of descent from sanidine-hosted inclusions that record high Sr and increasing Ba with crystallization, to quartz-hosted inclusions that record low Sr and decreasing Ba with crystallization. In the case of the Tara magmatic system, sanidine-hosted inclusions seem to record an earlier, deeper stage of the melt's history. Assessing melt inclusions within multiple phenocryst hosts may provide insights into different stages of a melt's history from storage to ascent and eruption.

However, from 1992-2014, there are still gaps in global volcano surveillance and only a fraction of the 1400 subaerial Holocene volcanoes have frequent observations in this time period. Starting in 2014, near global observations of volcano deformation should begin with the Sentinel satellites from the European Space Agency, ALOS-2 from the Japanese Space Agency, and eventually NISAR from the Indian Space Agency and NASA. With more frequent observations, more volcano deformation episodes are sure to be observed, but evaluating the significance of the observed deformation is not always straightforward -- how can we determine if deformation will lead to eruption? To answer this question, an international task force has been formed to create an inventory of volcano deformation events as part of the Global Volcano Model (http://globalvolcanomodel.org/gvm-task-forces/volcano-deformation-d atabase/). We present the first results from our global study focusing on volcanoes that have few or no previous studies. In some cases, there is a lack of SAR data (for example, volcanoes of the South Sandwich Islands). For others, observations either show an absence of deformation or possible deformation that requires more data to be verified. An example of a deforming volcano that has few past studies is Pagan, an island in the Marianas Arc comprised of 2 stratovolcanoes within calderas. Our new InSAR measurements from both the ALOS and Envisat satellites show deformation near the 1981 May VEI 4 lava flow eruption on North Pagan at 2-3 cm/year between 2004-2010. Another example of a newly observed volcano is Karthala volcano in the Comoros. InSAR observations between 2004-2010 span four eruptions, only one of which is accompanied by deformation.

Recent measurements of live magnetotactic bacteria demonstrate that such a "quantum diamond microscope" can image individual magnetic sources with 1 mm field-of-view, and magnetic moment sensitivity <10-16 A m2 under ambient temperatures and pressures. The unprecedented combination of spatial resolution and magnetic sensitivity of the quantum diamond microscope permits magnetic analyses of previously inaccessible geologic samples in which the regions of interest are mixed with undesirable magnetic field sources at the <<100 mu m scale. Here we apply this technique to chondritic meteorites, primordial aggregates formed during the accretional phase of the solar system. These meteorites consist of fine-grained matrix mixed with chondrules and other inclusions with characteristic sizes of 0.1-1 mm. Each chondrule records a unique magnetic history and potentially constrains nebular magnetic fields, which likely played a key role in accretion disk dynamics. The quantum diamond microscope is unique in its ability to resolve the magnetic signal of single inclusions from surrounding material. We applied the quantum diamond microscope to a variety of natural and artificial samples. Magnetic field maps of a single chondrule from the Allende CV carbonaceous chondrite show that the strongest magnetic sources are located in its 20 mu m thick rim. Magnetic field sources in the chondrule interior occur in the mesostasis as isolated 10-100 mu m patches that generate magnetic fields approximately 10 times weaker than the rim. These maps highlight the importance of spatial resolution for paleomagnetic measurements of chondrites; lower resolution measurements would permit the nearby rim material to dominate the magnetic signal, precluding accurate recovery of paleomagnetic data from chondrule interiors. In addition to these results we will report NV-diamond maps of other meteorites, including Antarctic finds, that contain secondary weathering veins. These maps will enable the exclusion of terrestrial magnetic signals in paleomagnetic analyses of these samples.

To examine the sources and amounts of geographic variation, we focused on long-term changes in the carbon cycle. We combined modern calibrations, delta 13C of biomarkers in sediment, and Monte Carlo analyses to measure and predict the fractionation of carbon isotopes by plants (Delta leaf) and to estimate error. We used data from multiple sites of different ages, in the western U.S. For each age and location, Delta leaf was calculated from the delta 13C of plant biomarkers and atmospheric delta 13C values inferred from marine carbonates. Delta leaf values calculated from n-alkanes and triterpenoids (angiosperm biomarkers) were found to be the same at each site. Delta leaf calculated from diterpenoids (conifer biomarkers) was 2 ppm lower. This is consistent with differences in Delta leaf between living angiosperms and conifers. Predicted Delta leaf values, from modern calibrations and paleoclimate data, were consistently offset (0.7 ppm) from measured values indicating that modern calibrations are useful for reconciling past changes in plant fractionation and that vegetation and precipitation, like modern plants, were the key controls on Delta leaf in ancient vegetation. However, uncertainties in the measured and predicted Delta leaf values were very large (>2 ppm, 1sigma ). A one-at-a-time sensitivity analysis indicates that 'biological noise' in modern calibrations explains most of this uncertainty. If the full extent of this biological noise were transferred to sediments, then extracting signal from noise would be challenging. However, we speculate that the process of deposition homogenizes variability at the leaf and tree level thereby reducing 'biological noise' observed in modern calibrations.

Methane emissions from wetlands are offset by their substantial ability to sequester carbon. We use best estimates from the literature to construct a radiative mass balance for trace gas emissions and soil carbon sequestration from the world's wetlands. We also distinguish between the static radiative balance of wetlands and their radiative forcing, with only the latter affecting climate. Large uncertainties in our estimates are particularly due to uncertainties in historical and current wetland area and soil sequestration rates in mineral-soil wetlands. Overall, we conclude that destruction of mineral-soil wetlands has likely had a global cooling effect (and vice-versa for restoration), whereas destruction of peatlands and marine-associated wetlands has had a warming effect using a 100 year global warming potential. We also emphasize the myriad goods and services that wetlands provide besides their effects on climate forcing.

However, aeolian megaripples (aka coarse-grained ripples or granule ripples) have bimodal grain size-frequencies. Distinguishing aeolian megaripple deposits from mixed grain size fluvial deposits is important, particularly for martian sedimentary rocks where implications for flowing water in the martian past (if revealed by legitimate fluvial deposits) are important mission drivers for rovers and landers. Aeolian megaripples are relatively minor components of terrestrial aeolian settings (e.g., as interdune features), but on Mars, megaripples have been encountered in many locations by landers and rovers, are durable due to indurated, armoring surface layers of very coarse sand, and therefore are likely candidates for preservation in the martian sedimentary rock record. Unfortunately, megaripple deposits preserved in martian sedimentary rocks must be recognized with much less data or context than obtained typically during terrestrial fieldwork. We have undertaken wind tunnel experiments and fieldwork to assist interpretations distinguishing aeolian megaripple deposits from mixed grain fluvial materials. Lags of coarse or very coarse sand from ancient aeolian environments within the White Rim Sandstone, Canyonlands NP, UT, and at some localities along the J2 Unconformity at Buckhorn Wash, UT, are well sorted, with a sharply defined maximum grain size in each case. We conducted wind tunnel experiments to explore whether the well-sorted, sharp cutoff in maximum grain size of the coarse fraction in these deposits could be diagnostic of aeolian megaripple formation and migration. Wind tunnel experiments involved 250 mu m sand saltating against 600-2800 mu m grains. For a given wind tunnel speed, only a narrow grain size range appeared on megaripple surfaces as these bedforms developed spontaneously from the bed; somewhat finer grains migrated rapidly downwind, while slightly coarser grains remained immobile. The physics of saltation-driven creep seems to explain this effect. Saltation-driven creep rapidly segregates the grains downwind according to size, partly because the mass of the coarse target grain increases greatly with only minor increases in grain radius and this can be only partly compensated by increasing the saltating grain speed.

I believe that giving students the opportunity for increased understanding of their own beliefs and values with respect to the environment will allow them to be more engaged in discussions and debates about environmental policies at the local, national, and global scales. I designed Environmental Geology of Prince William Forest Park (VA), a one-day Field Studies course offered through Northern Virginia Community College, to motivate students to articulate personal convictions about land use. To provide a social context for discussion of environmental issues, students first gave presentations on the demographics, economics, and methods of land use of the people that used the park over the last 400 years. At locations along Quantico Creek, students presented topics that covered geologic processes at work on the landscape, progressive farming methods promoted by some early Virginians, and agricultural methods to stabilize soil and its nutrients. Finally, at the Cabin Branch Pyrite Mine (active 1889-1920) we discussed laborer work conditions and the environmental impact of tailings, as well as the process and effects of remediation. Students tested pH levels in the creek upstream and downstream of the mine as one concrete way to personally observe the results of recent remediation (since 1994), with neutral pH in both locations indicating success. Students wrapped up the course with written reflections, from their own perspectives with respect to socially and environmentally responsible land use, on the geologic processes and human impacts that shaped the park. Social justice and environmental stewardship are two lenses that allow students to find personal meaning and social relevance in geology coursework, as emphasized in this field course. Many students, in this and other courses, have provided feedback indicating that activities I have developed and used along these lines are some of the most engaging and inspiring in their geology coursework.

The sediments of fossil localities typically provide, however, only short time windows into past climatic and environmental conditions. Continuous, long-term terrestrial records are now becoming available through core drilling to help elucidate the paleoenvironmental context of human evolution. Here we present a 500,000 year long high-resolution drill core record obtained from a key fossil and archeological site - the Olorgesailie Basin in the southern Kenya Rift Valley, well known for its sequence of archeological and faunal sites for the past 1.2 million years. In 2012 two drill cores (54 and 166 m long) were collected in the Koora Plain just south of Mt. Olorgesailie as part of the Olorgesailie Drilling Project (ODP) to establish a detailed climate and ecological record associated with the last evidence of Homo erectus in Africa, the oldest transition of Acheulean to Middle Stone Age technology, and large mammal species turnover, all of which are documented in the Olorgesailie excavations. The cores were sampled at the National Lacustrine Core Facility. More than 140 samples of tephra and trachytic basement lavas have led to high-precision 40Ar/39Ar dating. The cores are being analyzed for a suite of paleoclimatic and paleoecological proxies such as diatoms, pollen, fungal spores, phytoliths, ostracodes, carbonate isotopes, leaf wax biomarkers, charcoal, and clay mineralogy. Sedimentological analyses, including lithological descriptions, microscopic smear slide analysis (242 samples), and grain-size analysis, reveal a highly variable sedimentary sequence of deep lake phases with laminated sediments, diatomites, shallow lake and near shore phases, fluvial deposits, paleosols, interspersed carbonate layers, and abundant volcanic ash deposits. Magnetic susceptibility indicates climatic variation potentially related to precessional cycles.

The oxidized nature of Mariana arc magmas is likely acquired through the transfer of oxidized species from the slab to the mantle wedge via aqueous fluids [1]. Despite its critical role in the relationship between material recycling at subduction zones and oxidation, it is unclear what percentage of the oxidized material is transported into the mantle wedge and output during volcanism and what percentage is transported past subduction zones, into the deep mantle. We present Fe (super 3+) /Sigma Fe ratios determined on bulk sediments and altered oceanic crust recovered from ODP Site 801 in the western Pacific in order to constrain the bulk oxidation state of the Pacific plate prior to subduction. We performed micro-colorimetric determinations of the Fe (super 2+) O contents of 9 sediment samples, 8 variably altered MORBs, 5 alteration products, and 8 mixed composite powders from the sediment and upper 500 m of altered oceanic crust at ODP Site 801. Site 801 sediments have Fe (super 3+) /Sigma Fe ratios >0.69 and the altered oceanic crust (801 Super Composite) has Fe (super 3+) /Sigma Fe=0.51. Bulk Fe (super 3+) /Sigma Fe ratios of altered oceanic crust at Site 801 increase from 0.16 (pristine MORB glass measured by XANES, [2]) to 0.78 with increasing extent of alteration. Using bulk Fe (super 3+) /Sigma Fe ratios determined here, and Fe redox information from [1] and [2], we calculated a mass balance of Fe (super 3+) and O (sub 2) equivalent through the Mariana subduction zone. We subtracted the Fe (super 3+) of pristine oceanic crust from that of altered oceanic crust to estimate the amount of Fe (super 3+) taken up by oceanic crust during alteration on the seafloor. Comparing this value to the output of Fe (super 3+) from Mariana arc and back-arc lavas, we find that 50-70% of the O (sub 2) equivalent added to the oceanic crust by alteration on the seafloor is not output by arc or back-arc magmas. If this oxygen is retained in the slab that subducts into the deep mantle, it may contribute to mantle redox heterogeneity. [1] Brounce, M. N., Kelley, K. A., and Cottrell, E. in revision.

Ripple orientations have been documented using HiRISE images of sand dunes at 24 widely distributed sites across Mars, in order to identify the last significant wind directions at these locations. Howard (GSAB, 1977) gives a mathematical expression for how surface slopes on a sand dune can affect the orientation of ripples with respect to the formative winds. In order to evaluate this mechanism for measured ripple orientations on Mars, quantitative data for surface slopes on the sand dunes is required. Stereo pairs of HiRISE images are used to generate Digital Terrain Models (DTMs) with postings of one meter. In June 2014 we produced a DTM of sand dunes in the Terra Tyrrhena region of Mars (14.55 degrees S, 97.77 degrees E) using SOCET SET at the Astrogeology Branch, USGS-Flagstaff. Typically it is difficult for feature matching software to work well on sand dunes, but our stereo images (ESP (sub 022609) (sub 1655) and ESP (sub 026675) (sub 1655) ) were obtained only six Earth days apart under excellent illumination conditions. The Terra Tyrrhena DTM had remarkably few artifacts on the sand dunes (except at slip faces, where the average slope between slip face crest and base was interpolated) and excellent control from irregular terrain exposed in interdune areas. Slopes on the stoss sides of sand dunes are generally <10 degrees ; the Howard equation indicates ripple deflection angles should be <17 degrees with respect to the actual surface wind direction. We are adjusting documented ripple orientations to account for surface slopes utilizing the DTM data, and so far we do not see major changes to inferred surface wind directions that would be derived directly from the ripple orientations.

Yet, such melts provide essential views of mantle-derived melts, without further modification by fractional crystallization or other crustal processes, and reveal the diversity of melt compositions that exist in the arc mantle wedge. Here, we present new measurements of naturally glassy, near-primary olivine-hosted melt inclusions from one dredge of Evita seamount (SS07/2008NLD-02) in the southern Vanuatu arc system. Two distinct basalt types were identified in hand sample upon collection, based on contrasting phenocryst assemblage (Type 1: 1% phenocrysts; Type 2: 15% phenocrysts). We selected melt inclusions from each type and determined major elements, S, and Cl by EMP, H (sub 2) O and CO (sub 2) by FTIR, trace elements by LA-ICP-MS, and Fe (super 3+) /Sigma Fe ratios by XANES. Melt inclusions from both lava types show equilibrium with > or =Fo (sub 90) olivine, consistent with host olivine compositions, and thus are near-primary melt compositions that have escaped major modification since departing the mantle wedge. Both have similar maximum dissolved H (sub 2) O ( nearly equal 2.3 wt.%), high Mg# (48-75), and are basalt to basaltic andesite (SiO (sub 2) 49-55 wt.%). However, the two lava types have very different major and trace element compositions. Inclusions from Type 1 show relatively flat REE patterns and classic negative anomalies in Nb and Ta, and positive anomalies in Pb and Sr typical of normal arc basalts, and have Fe (super 3+) /Sigma Fe ratios similar to global arc basalts ( nearly equal 0.24). In contrast, melt inclusions from Type 2 exhibit steeply sloped REE patterns with strong depletions in the HREE that suggest garnet in the source lithology for these magmas, either in the subducting slab or the mantle wedge. Moreover, the Type 2 inclusions have high La/Yb (29.5-43) and Sr/Y (50-58), which are classically attributed to partial melting of the basaltic slab, although these inclusions are basaltic, not andesitic. Type 2 inclusions also have Fe (super 3+) /Sigma Fe ratios that are among the highest measured in natural terrestrial glasses ( nearly equal 0.32). The compositions of these near-primary basalts indicate that melts of the mantle wedge, and perhaps melts of the slab, form under oxidizing conditions.

Because of their prime location and rich peat soil, many wetlands have been reduced, degraded, and/or destroyed, and yet their important role in carbon sequestration, nutrient and sediment filtering, and as habitat requires us to further examine their sustainability in light of predicted climate change. Predictions of climate change effects for the San Francisco Bay Estuary present a future with reduced summer freshwater input and increased sea levels. We examined the applicability and accuracy of the Marsh Equilibrium Model (MEM), a zero-dimensional model that models organic and inorganic accretion rates under a given rate of sea-level rise. MEM was calibrated using data collected from salt and brackish marshes in the San Francisco Bay Estuary to examine wetland resiliency under a range of sea-level rise and suspended sediment concentration scenarios. At sea-level rise rates 100 cm/century and lower, wetlands remained vegetated. Once sea levels rise above 100 cm, marshes begin to lose ability to maintain elevation, and the presence of adjacent upland habitat becomes increasingly important for marsh migration. The negative effects of sea-level rise on elevations were compounded as suspended sediment concentrations decreased. Results from this study emphasize that the wetland landscape in the bay is threatened with rising sea levels, and there are a limited number of wetlands that will be able to migrate to higher ground as sea levels rise.

Previous studies indicated that conifer n-alkane concentrations are lower than in angiosperms and that 13C fractionation during n-alkane synthesis (epsilon lipid) is smaller than in angiosperms. These prior studies, however, sampled a limited phylogenetic and geographic subset of conifers, leaving out many important subtropical and Southern Hemisphere groups that were once widespread and common components of fossil assemblages. To expand on previous work, we collected 44 conifer species from the University of California Botanical Garden at Berkeley, capturing all extant conifer families and most extant genera. By collecting all specimens at a common site we attempted to minimize the confounding effects of climate, allowing phylogenetic patterns in the delta 13C of leaf waxes to be expressed more strongly. We find that Pinaceae, including many North American species used in previous studies, have very low or no n-alkanes. However, other conifer groups have significant concentrations of n-alkanes, especially the Araucariaceae (Norfolk Island pines), Podocarpaceae (common in the Southern Hemisphere), and many species of Cupressaceae (junipers and relatives). Within the Cupressaceae, we find total n-alkane concentrations are high in subfamilies Cupressoideae and Callitroideae, but significantly lower in the early diverging taxodioid lineages (including bald cypress and redwood). Individual n-alkane chain lengths have a weak phylogenetic signal, except for n-C29 alkane, but when combined using average chain length (ACL), a strong phylogenetic signal emerges. The strong phylogenetic signal in ACL reinforces that it is strongly influenced by factors other than climate. An analysis of epsilon lipid indicates a strong phylogenetic signal in which the smallest biosynthetic fractionation occurs in Pinaceae and the largest in Taxaceae (yews and relatives). We are currently exploring potential mechanisms to explain the epsilon lipid patterns. These results have important implications for interpreting n-alkane delta 13C values in sedimentary archives, especially outside of North America.

The O-isotope compositions of matrix from Queen Alexandra Range 99177 confirm that this sample is the least aqueously altered CR chondrite, provides the best approximation of the primary anhydrous matrix, and suggests matrix is not a byproduct of chondrule formation. Matrix O-isotope compositions within individual CR chondrites are heterogeneous, varying up to approximately 5ppm in both delta (super 18) O and delta (super 17) O, as a result of the heterogeneous nature of the matrix and diverse range of aqueous alteration recorded by each sample. Aqueous alteration resulted in matrix that is progressively more (super 16) O-depleted and Ca-carbonate rich. Due to the fine-grained nature of matrix its O-isotope composition is a more sensitive indicator of a chondrite's overall degree of aqueous alteration than whole-rock O-isotope compositions, which are typically dominated by the compositions of type I (FeO-poor) chondrule phenocrysts. Petrographic signatures correlate with the degree of aqueous alteration and the wide range of matrix O-isotope compositions indicate that some regions of the CR chondrite parent asteroid were relatively dry, while others were heavily hydrated with water. The O-isotope composition of aqueously altered matrix is consistent with asteroidal water being near Delta (super 17) O approximately 0ppm, which suggests an inner Solar System origin for the water. The diverse range of aqueous alteration recorded by a single asteroid has a range of implications for spectral studies of the asteroid belt, and the arrival of Dawn at 1 Ceres, Hayabusa-2 at 162173 1999 JU3, and OSIRIS-REx at 101955 Bennu.

AN - 1692745931; 2015-065394 AB - Our understanding of submarine volcanism is in its infancy with respect to subaerial eruption processes. Two fundamental differences between eruptions in seawater compared to those on land are that (1) eruptions occur at higher confining pressures, and (2) in a seawater medium, which has a higher heat capacity, density and viscosity than air. Together with JAMSTEC collaborators we have a sample suite of submarine pumice deposits from modern volcanoes of known eruption depths. This sample suite spans a spectrum of eruption intensities, from 1) powerful explosive caldera-forming (Myojin Knoll caldera); to 2) weakly explosive cone building (pre-caldera Myojin Knoll pumice and Kurose-Nishi pumice); to 3) volatiledriven effusive dome spalling (Sumisu knoll A); to 4) passive dome effusion (Sumisu knoll B and C). This sample suite has exceptional potential, not simply because the samples have been taken from well-constrained, sources but because they have similar high silica contents, are unaltered and their phenocrysts contain melt inclusions. Microtextural quantitative analysis has revealed that (i) clast vesicularities remain high (69-90 vol.%) regardless of confining pressure, mass eruption rate or eruption style, (ii) vesicle number densities scale with inferred eruption rate, and (iii) darcian and inertial permeabilities of submarine effusive and explosive pyroclasts overlap with explosively-erupted subaerial pyroclasts.

A global negative correlation between CO2/Nb (proxy for amount of CO2 lost by degassing) and Ba/La (proxy for source enrichment) indicates that depleted MORB are less affected by degassing than enriched MORB: CO2/Nb ratios range from 0-100 for samples with Ba/La>4, while CO2/Nb range from 50 to 400 for samples with Ba/La<4. To assess the CO2 content of undegassed MORB, we analyzed the volatile content of 70 olivine-hosted, glassy melt inclusions (MIs) from four basalts dredged along MAR 1-5 degrees S, a ridge segment that produces highly depleted MORB in terms of trace element enrichment and radiogenic isotopes. MIs contain CO2 contents (180-1420 ppm) that are higher than their respective matrix glasses (130-220 ppm, typical for vapor-saturated melts erupted at 3-5 km b.s.l.). One of the four dredges (EN061 5D-3Ag) contains MIs that do not exhibit shrinkage bubbles. For this sample only, we find a positive correlation between the CO2 content (240-770 ppm) and the Cl content (6-20 ppm) of the MIs that is not found in the matrix glasses. We infer that the correlation between CO2 and Cl, both highly incompatible in silicate minerals during fractional crystallization, is strong evidence for vapor-undersaturation, as any CO2 degassing would have erased the correlation. Together with MIs from the Siqueiros Fracture Zone and from northern Iceland, the MIs from EN061 5D-3Ag may represent another occurrence of carbon-undersaturated MORB. Our results will be used to model the primary carbon content of MORB and of the depleted upper mantle. Note that the average Cl content of the matrix glasses (20+ or -1 ppm) is higher than those of the MIs (12+ or -3 ppm, see Fig.). This indicates either that the matrix glasses assimilated a small amount of seawater Cl, or that the MIs are all more depleted than the matrix glass. We will acquire major and trace element data in order to further investigate the origin of the low Cl and high CO2 contents in these MIs.

The results of this study are inconsistent with its initial classification as a Renazzo-like carbonaceous chondrite, and strongly support RBT 04133 being a brecciated, reduced petrologic type >3.3 Vigarano-like carbonaceous (CV) chondrite. RBT 04133 shows no evidence for aqueous alteration. However, it is mildly thermally altered (up to approximately 440 degrees C); which is apparent in its whole-rock C and N isotopic compositions, the degree of disorder of C in insoluble organic matter, low presolar grain abundances, minor element compositions of Fe,Ni metal, chromite compositions and morphologies, and the presence of unequilibrated silicates. Sulfides within type I chondrules from RBT 04133 appear to be pre-accretionary (i.e., did not form via aqueous alteration), providing further evidence that some sulfide minerals formed prior to accretion of the CV chondrite parent body. The thin section studied contains two reduced CV3 lithologies, one of which appears to be more thermally metamorphosed, indicating that RBT 04133, like several other CV chondrites, is a breccia and thus experienced impact processing. Linear foliation of chondrules was not observed implying that RBT 04133 did not experience high velocity impacts that could lead to extensive thermal metamorphism. Presolar silicates are still present in RBT 04133, although presolar SiC grain abundances are very low, indicating that the progressive destruction or modification of presolar SiC grains begins before presolar silicate grains are completely unidentifiable.

In contrast to bacteria, the pathways utilized by fungi to oxidize Mn(II) to Mn(III,IV) oxides remain largely unknown. Here, we explore the mechanisms of Mn(II) oxidation by a phylogenetically diverse group of filamentous Ascomycete fungi using a combination of chemical assays and bulk and spatially-resolved mass spectrometry. We show that the mechanisms of Mn(II) oxidation vary with fungal species, over time during secretome compositional changes, and in the presence of other fungi. Specifically, our work implicates a dynamic transition in Mn(II) oxidation pathways that varies between species. In particular, while reactive oxygen species (ROS) produced via transmembrane NADPH oxidases are involved in initial oxidation, over time, secreted enzymes become important Mn(II) oxidation mediators for some species. In addition, the overall secretome oxidation capacity varies with time and fungal species. Secretome analysis reveals a surprising absence of enzymes currently considered to be Mn(II)-oxidizing enzymes in these organisms, and instead highlights a wide variety of redox-active enzymes. Furthermore, we implicate fungal cell defense mechanisms in the formation of distinct Mn oxide patterns when fungi are grown in head-to-head competition. The identification and regulation of these secreted enzymes are under current investigation within the bulk secretome and within the interaction zone of structured fungal communities. Overall, our findings illustrate that Ascomycete Mn(II) oxidation mechanisms are highly variable and are dictated by complex environmental and ecological interactions. Future work will explore the connection between Ascomycete Mn(II) oxidation and the ability to degrade cellulose, a key carbon reservoir for biofuel production.

Distinguishing between these two hypotheses is important for understanding redox-sensitive processes related to arc magmatism, and thus more broadly how Earth materials cycle globally. We present major, volatile, and trace element concentrations in combination with Fe (super 3+) /Sigma Fe ratios determined in olivine-hosted glass inclusions and submarine glasses from five Mariana arc volcanoes and two regions of the Mariana Trough. For single eruptions, Fe (super 3+) /Sigma Fe ratios vary along liquid lines of descent that are either slightly oxidizing (olivine + clinopyroxene + plagioclase fractionation, CO (sub 2) + or - H (sub 2) O degassing) or reducing (olivine + clinopyroxene + plagioclase + or - magnetite fractionation, CO (sub 2) + H (sub 2) O + S degassing). Mariana samples are consistent with a global relationship between calc-alkaline affinity and both magmatic H (sub 2) O and magmatic oxygen fugacity, where wetter, higher oxygen fugacity magmas display greater affinity for calc-alkaline differentiation. We find, however, that low-pressure differentiation cannot explain the majority of variations observed in Fe (super 3+) /Sigma Fe ratios for Mariana arc basalts, requiring primary differences in magmatic oxygen fugacity. Calculated oxygen fugacities of primary mantle melts at the pressures and temperatures of melt segregation are significantly oxidized relative to mid-ocean ridge basalts ( approximately QFM, where QFM is quartz-fayalite-magnetite buffer), ranging from QFM + 1.0 to QFM + 1.6 for Mariana arc basalts, whereas back-arc related samples record primary oxygen fugacities that range from QFM + 0.1 to QFM + 0.5. This Mariana arc sample suite includes a diversity of subduction influences, from lesser influence of a homogeneous H (sub 2) O-rich component in the back-arc, to sediment melt- and fluid-dominated influences along the arc. Primary melt oxygen fugacity does not correlate significantly with sediment melt contributions (e.g. Th/La), nor can it be attributed to previous melt extraction in the back-arc. Primary melt oxygen fugacity correlates strongly with indices of slab fluids (e.g. Ba/La) from the Mariana Trough through the Mariana arc, increasing by 1.5 orders of magnitude as Ba/La increases by a factor of 10 relative to mid-ocean ridge basalts. These results suggest that contributions from the slab to the mantle wedge may be responsible for the elevated oxygen fugacity recorded by Mariana arc basalts and that slab fluids are potentially very oxidized.

AN - 1660630144; 2015-021776 AB - Tropical wetlands are not included in Earth system models, despite being an important source of methane (CH (sub 4) ) and contributing a large fraction of carbon dioxide (CO (sub 2) ) emissions from land use, land use change, and forestry in the tropics. This review identifies a remarkable lack of data on the carbon balance and gas fluxes from undisturbed tropical wetlands, which limits the ability of global change models to make accurate predictions about future climate. We show that the available data on in situ carbon gas fluxes in undisturbed forested tropical wetlands indicate marked spatial and temporal variability in CO (sub 2) and CH (sub 4) emissions, with exceptionally large fluxes in Southeast Asia and the Neotropics. By upscaling short-term measurements, we calculate that approximately 90 + or - 77 Tg CH (sub 4) year (super -1) and 4540 + or - 1480 Tg CO (sub 2) year (super -1) are released from tropical wetlands globally. CH (sub 4) fluxes are greater from mineral than organic soils, whereas CO (sub 2) fluxes do not differ between soil types. The high CO (sub 2) and CH (sub 4) emissions are mirrored by high rates of net primary productivity and litter decay. Net ecosystem productivity was estimated to be greater in peat-forming wetlands than on mineral soils, but the available data are insufficient to construct reliable carbon balances or estimate gas fluxes at regional scales. We conclude that there is an urgent need for systematic data on carbon dynamics in tropical wetlands to provide a robust understanding of how they differ from well-studied northern wetlands and allow incorporation of tropical wetlands into global climate change models.

Large variations in depth/diameter (d/D) between impact sites indicate that differences between the sites such as target material properties, impact velocity, angle, and physical state of the bolide(s) are important in determining the depth of small craters in the strength regime. On the Moon, the d/D of random fresh small craters with similar diameters averages only 0.10, indicating that either the majority of them are unrecognized secondaries or some proportion are degraded primaries. Older craters such as these may be shallower due to erosional infilling, which is probably not linear over time but more effective over recently disturbed and steeper surfaces, processes that are not yet acting on the new Martian craters. Brand new meter- to decameter-scale craters such as the Martian ones studied here are statistically easily distinguishable as primaries, but the origins of older craters of the same size, such as the lunar ones in this study, are ambiguous.

The present study of the Gulf of Chiriqui complements our previous study of nesting waterbirds of the Gulf of Panama. In April 2012, about 4,000 nests of seven species of seabirds and other colonial waterbirds were identified during a complete survey by small plane and boat within and adjacent to the Gulf of Chiriqui. Seventeen colony sites were found, 12 of which are reported here for the first time. Nesting species included Brown Booby (Sula leucogaster; the most abundant species with nearly 2,500 nests), Brown Pelican (Pelecanus occidentalis), Magnificent Frigatebird (Fregata magnificens), Bridled Tern (Onychoprion anaethetus; second nesting site for Panama), Wood Stork (Mycteria americana; third nesting site for Panama), Great Egret (Ardea alba), and Cattle Egret (Bubulcus ibis). The largest nesting site in the Gulf of Chiriqui was the Islas Ladrones, with 2,200 Brown Booby nests (the largest site for this species in Panama) and 130 Magnificent Frigatebird nests. Unlike most of the sites found in this study, these islands are not currently officially protected.

While many suggestive correlative occurrence models have been used to these ends, progress lies in understanding the underlying population biology that generates patterns of range dynamics. Here, we show how to use a limited quantity of demographic data to produce demographic distribution models (DDMs) using integral projection models for size-structured populations. By modeling survival, growth, and fecundity using regression, integral projection models can interpolate across missing size data and environmental conditions to compensate for limited data. To accommodate the uncertainty associated with limited data and model assumptions, we use Bayesian models to propagate uncertainty through all stages of model development to predictions. DDMs have a number of strengths: 1) DDMs allow a mechanistic understanding of spatial occurrence patterns; 2) DDMs can predict spatial and temporal variation in local population dynamics; 3) DDMs can facilitate extrapolation under altered environmental conditions because one can evaluate the consequences for individual vital rates. To illustrate these features, we construct DDMs for an overstory perennial shrub in the Proteaceae family in the Cape Floristic Region of South Africa. We find that the species' population growth rate is limited most strongly by adult survival throughout the range and by individual growth in higher rainfall regions. While the models predict higher population growth rates in the core of the range under projected climates for 2050, they also suggest that the species faces a threat along arid range margins from the interaction of more frequent fire and drying climate. The results (and uncertainties) are helpful for prioritizing additional sampling of particular demographic parameters along these gradients to iteratively refine projections. In the appendices, we provide fully functional R code to perform all analyses.

AN - 1642613228; 21136393 AB - Species distribution models (SDMs) are widely used to explain and predict species ranges and environmental niches. They are most commonly constructed by inferring species' occurrence-environment relationships using statistical and machine-learning methods. The variety of methods that can be used to construct SDMs (e.g. generalized linear/additive models, tree-based models, maximum entropy, etc.), and the variety of ways that such models can be implemented, permits substantial flexibility in SDM complexity. Building models with an appropriate amount of complexity for the study objectives is critical for robust inference. We characterize complexity as the shape of the inferred occurrence-environment relationships and the number of parameters used to describe them, and search for insights into whether additional complexity is informative or superfluous. By building 'under fit' models, having insufficient flexibility to describe observed occurrence-environment relationships, we risk misunderstanding the factors shaping species distributions. By building 'over fit' models, with excessive flexibility, we risk inadvertently ascribing pattern to noise or building opaque models. However, model selection can be challenging, especially when comparing models constructed under different modeling approaches. Here we argue for a more pragmatic approach: researchers should constrain the complexity of their models based on study objective, attributes of the data, and an understanding of how these interact with the underlying biological processes. We discuss guidelines for balancing under fitting with over fitting and consequently how complexity affects decisions made during model building. Although some generalities are possible, our discussion reflects differences in opinions that favor simpler versus more complex models. We conclude that combining insights from both simple and complex SDM building approaches best advances our knowledge of current and future species ranges.

We used NaOH-EDTA extraction and solution super(31)P NMR spectroscopy to examine changes in soil phosphorus composition along the Haast chronosequence, a 6,500 year sequence of coastal dunes under lowland temperate rain forest on the west coast of the South Island of New Zealand. Soils along the chronosequence contained a variety of inorganic (orthophosphate, pyrophosphate, and long-chain polyphosphate) and organic (phosphomonoesters, phosphodiesters, and phosphonates) phosphorus compounds, although long-chain polyphosphates were detected only in the organic horizon and phosphonates were detected only in mineral soil. The concentrations of most compounds increased initially during the first few hundred years of pedogenesis and then declined as soils aged. However, concentrations of phospholipids, DNA, and long-chain polyphosphate all increased markedly in the organic horizon of older sites. The four inositol hexakisphosphate stereoisomers (myo, scyllo, neo, and d-chiro) accounted for a considerable proportion of the phosphomonoesters in mineral soil along the sequence (36-52 % of the organic phosphorus), but were not detected in quantifiable concentrations in the youngest mineral soil and all but one organic horizon. Concentrations of the two most abundant isomers (myo- and scyllo) declined along the chronosequence, but the scyllo isomer increased markedly as a proportion of the soil organic phosphorus as soils aged. Amorphous aluminum and iron oxides (i.e., extractable in acid-ammonium oxalate) increased continually throughout the chronosequence, indicating that the decline in inositol hexakisphosphate is due to low phosphorus availability rather than a decline in stabilization potential. Overall, these results provide further evidence that the chemical composition of organic and inorganic phosphorus pools vary markedly during pedogenesis, which has important implications for our understanding of biologically-available organic phosphorus during ecosystem development.

However, there have been no experimental constraints on the intensity of these fields. Here we show that dusty olivine-bearing chondrules from the Semarkona meteorite were magnetized in a nebular field of 54+ or -21 microteslas. This intensity supports chondrule formation by nebular shocks or planetesimal collisions rather than by electric currents, the x-wind, or other mechanisms near the Sun. This implies that background magnetic fields in the terrestrial planet-forming region were likely 5 to 54 microteslas, which is sufficient to account for measured rates of mass and angular momentum transport in protoplanetary disks.

It is, however, likely that the architecture of the solar system underwent a dynamical instability-driven transformation, where the primordial configuration was more compact. Hence, the characteristic frequencies associated with orbital perturbations were likely faster in the past, potentially allowing for secular resonant encounters. In this work, we examine if, at any point in the Earth's evolutionary history, the obliquity varied significantly. Our calculations suggest that even though the orbital perturbations were different, the system nevertheless avoided resonant encounters throughout its evolution. This indicates that the Earth obtained its current obliquity during the formation of the Moon. Copyright (Copyright) 2014. The American Astronomical Society. All rights reserved.

Radar measurements of the dielectric properties of these flows can provide information regarding their composition and density. SHARAD (shallow radar), a sounding radar on the Mars Reconnaissance Orbiter, detects basal interfaces beneath flows in some areas of Tharsis northwest and west of Ascraeus Mons, with additional detections south of Pavonis Mons. Comparisons with 12.6 cm ground-based radar images suggest that SHARAD detects basal interfaces primarily in dust or regolith-mantled regions. We use SHARAD data to estimate the real relative permittivity of the flows by comparing the measured time delay of returns from the subsurface with altimetry measurements of the flow heights relative to the surrounding plains. In cases where the subsurface interface is visible at different depths, spanning tens of meters, it is also possible to measure the loss tangent (tan delta ) of the material. The permittivity values calculated range from 7.6 to 11.6, with an average of 9.6, while the mean loss tangent values range from 7.8 X 10 (super -3) to 2.9 X 10 (super -2) with an average of 1.0 X 10 (super -2) . These permittivity and loss tangent estimates for the flows northwest of Ascraeus Mons, west of Ascraeus Mons, and south of Pavonis Mons are consistent with the lab-measured values for dense, low-titanium basalt.

It occurs as rare crystals up to approximately 10 mu m across in meteoritic fragments that contain evidence of a heterogeneous distribution of pressures and temperatures during impact shock, in which some portions of the meteorite reached at least 5 GPa and 1200 degrees C. The meteorite fragments contain the high-pressure phases ahrensite, coesite, stishovite, and an unnamed spinelloid with composition Fe (sub 3-) (sub x) Si (sub x) O (sub 4) (x nearly equal 0.4). Other minerals include trevorite, Ni-Al-Mg-Fe spinels, magnetite, diopside, forsterite, clinoenstatite, nepheline, pentlandite, Cu-bearing troilite, icosahedrite, khatyrkite, cupalite, taenite, and Al-bearing taenite. Given the exceedingly small grain size of steinhardtite, it was not possible to determine most of the physical properties for the mineral. A mean of 9 electron microprobe analyses (obtained from two different fragments) gave the formula Al (sub 0.38) Ni (sub 0.32) Fe (sub 0.30) , on the basis of 1 atom. A combined TEM and single-crystal X-ray diffraction study revealed steinhardtite to be cubic, space group Im3m, with a = 3.0214(8) Aa, and V = 27.58(2) Aa (super 3) , Z = 2. In the crystal structure [R (sub 1) = 0.0254], the three elements are disordered at the origin of the unit cell in a body-centered-cubic packing (alpha -Fe structure type). The five strongest powder-diffraction lines [d in Aa (I/I (sub 0) ) (hkl)] are: 2.1355 (100) (110); 1.5100 (15) (200); 1.2329 (25) (211); 0.9550 (10) (310); 0.8071 (30) (321). The new mineral has been approved by the IMA-NMNC Commission (2014-036) and named in honor of Paul J. Steinhardt, Professor at the Department of Physics of Princeton University, for his extraordinary and enthusiastic dedication to the study of the mineralogy of the Khatyrka meteorite, a unique CV3 carbonaceous chondrite containing the first natural quasicrystalline phase icosahedrite. The recovery of the polymorph of Al described here that contains essential amounts of Ni and Fe suggests that Al could be a contributing candidate for the anomalously low density of the Earth"s presumed Fe-Ni core.

Closed canopies have pronounced effects on local, continental and global rainfall and temperature patterns. Although evidence for canopy closure is difficult to reconstruct from the fossil record, the characteristic isotope gradients of the "canopy effect" could be preserved in leaves and proxy biomarkers. To assess this, we employed new carbon isotopic data for leaves collected in diverse light environments within a deciduous, temperate forest (Maryland, USA) and for leaves from a perennially closed canopy, moist tropical forest (Bosque Protector San Lorenzo, Panama). In the tropical forest, leaf carbon isotope values range 10 ppm, with higher delta (super 13) C (sub leaf) values occurring both in upper reaches of the canopy, and with higher light exposure and lower humidity. Leaf fractionation (Delta (sub leaf) ) varied negatively with height and light and positively with humidity. Vertical (super 13) C enrichment in leaves largely reflects changes in Delta (sub leaf) , and does not trend with delta (super 13) C of CO (sub 2) within the canopy. At the site in Maryland, leaves express a more modest delta (super 13) C range ( approximately 6 ppm), with a clear trend that follows both light and leaf height. Using a model we simulate leaf assemblage isotope patterns from canopy data binned by elevation. The re-sampling (bootstrap) model determined both the mean and range of carbon isotope values for simulated leaf assemblages ranging in size from 10 to over 1000 leaves. For the tropical forest data, the canopy's isotope range is captured with 50 or more randomly sampled leaves. Thus, with a sufficient number of fossil leaves it is possible to distinguish isotopic gradients in an ancient closed canopy forest from those in an open forest. For very large leaf assemblages, mean isotopic values approximate the delta (super 13) C of carbon contributed by leaves to soil and are similar to observed delta (super 13) C (sub litter) values at forested sites within Panama, including the site where leaves were sampled. The model predicts a persistent approximately 1 ppm difference in delta (super 13) C (sub litter) for the two sites which is consistent with higher water availability in the tropical forests. This work provides a new framework for linking contemporary ecological observations to the geochemical record using flux-weighted isotope data and lends insights to the effect of forest architecture on organic and isotopic records of ancient terrestrial ecosystems.

With forests now being altered at an unprecedented rate, avian frugivores are becoming increasingly vital for forest regeneration. Seed movement, however, is highly dependent on the behavioral characteristics of their dispersers. Here, we examined the movements, habitat preferences, and range sizes of two African frugivores: the Black-casqued (Ceratogymna atrata) and the White-thighed (Bycanistes albotibialis) Hornbill, in the lowland rain forests of southern Cameroon. Using satellite transmitters, we tracked eight hornbills for 3 yr to characterize their movements and relate them to environmental landscape features. Hornbill movements differed significantly, with B. albotibialis ranging over larger areas (mean = 20,274 ha) than C. atrata (mean = 5604 ha), and females of both species covering over 15 times the area of males. Evidence suggests that movements are irruptive during particular periods, perhaps driven by low resource availability. In addition, hornbills often returned to the same localities within a year, although movements were not characterized as migratory. Both species displayed significant differences in habitat preference, with B. albotibialis utilizing disturbed habitat more frequently than C. atrata (t = -22.04, P = 2.2 10 super(-16)). Major roads were found to act as barriers for C. atrata, but not for B. albotibialis. The ability of both hornbill species to move large distances suggests hornbills will play a vital role in the maintenance and regeneration of rain forests in Central Africa as forest fragmentation increases and terrestrial vertebrates decline in numbers.Original Abstract: Resume Conservation des forets tropicales et de la restauration, il faut comprendre les mouvements et les preferences d'habitat des disseminateurs de graines importantes. Avec ses forets actuellement modifies a un rythme sans precedent, les oiseaux frugivores sont de plus en plus vital pour la regeneration de la foret. mouvement des semences, cependant, est tres dependante des caracteristiques comportementales de leurs dispersants. Ici, nous avons examine les mouvements, les preferences en matiere d'habitat, de tailles et de gamme de deux frugivores africaines: le (Ceratogymna atrata) noir a casque et le calao a cuisses blanches (Bycanistes albotibialis), dans les forets tropicales de plaine du sud du Cameroun. L'aide d'emetteurs satellites, nous avons suivi huit calaos pendant trois ans pour caracteriser leurs mouvements et de les relier a des elements du paysage de l'environnement. mouvements de Calao differaient significativement, avec B. albotibialis allant sur de grandes surfaces (moyenne = 20,274 ha) que C. atrata (moyenne = 5604 ha), et les femelles des deux especes couvrant plus de 15 fois la superficie des hommes. Les preuves suggerent que les mouvements sont irruptive durant des periodes determinees, peut-etre entraines par la faible disponibilite des ressources. En outre, les calaos souvent renvoyes aux memes localites situees dans un an, meme si les mouvements ne sont pas caracterises comme migratoire. Les deux especes apparaissent des differences significatives dans les preferences de l'habitat, avec B. albotibialis utilisant habitat perturbe plus frequemment que C. atrata (t = -22.04, P = 2.2 10 super(-16)). Les routes principales ont ete trouves a agir comme des barrieres pour C. atrata, mais pas pour B. albotibialis. La capacite des deux especes de calao de deplacer de grandes distances suggere calaos joueront un role essentiel dans le maintien et la regeneration des forets en Afrique centrale que la fragmentation de la foret augmente et les vertebres terrestres baisse du nombre.

We used spatial-statistical models to identify estuarine shoreline characteristics that explain variations in SAV abundance among subestuaries of the Chesapeake Bay and mid-Atlantic Coastal Bays. We summarized digital spatial data on shoreline construction, shoreline land use, physical characteristics, watershed land cover, and salinity for each subestuary. We related SAV abundance to shoreline characteristics and other stressors using univariate regression and multivariate models. The strongest univariate predictors of SAV abundance were percent shoreline forest, percent shoreline marsh, the percentage of shoreline that is 5-10 m tall, percent riprap, the percentage of subestuary area 5.4 % riprap. SAV abundance has increased steadily since 1984 in subestuaries with 5.4 % riprap. Some shoreline characteristics interact with larger-scale factors like land cover and salinity zone to affect the distribution of SAV, while the effects of other shoreline characteristics are consistent among subestuaries with different salinities or local watershed land covers. Many shoreline characteristics can be controlled by management decisions, and our results help identify factors that managers should consider in efforts to increase SAV abundance.

Historical propagule supply may have played a role in forming this trend, but few studies have evaluated propagule supply to northern latitudes. Here, we examined the role of small boat traffic as a mechanism of long-distance spread for nonindigenous species (NIS) into coastal Alaska. We used a combination of public records, marina surveys, and boater interviews to characterize vessel traffic patterns and boater behaviors. In-water SCUBA sampling of recently arrived transient boats provided data on extent, richness, composition, and biogeography of biofouling incursions to Alaska from outside of the state. We documented a striking seasonality and directionality of vessel traffic, and most vessels were on voyages of >900 km. Most transient vessels sampled had few organisms, although one third had >100 organisms on submerged surfaces. Several NIS were recorded, including two that are not known to be established in Alaska (Watersipora subtorquata and Amphibalanus improvisus). The seasonal northward pulse of vessels and their cumulative biofouling species represent an important incursion mechanism for species yet to establish at the northern edge of a marine bioinvasion front in the northeastern Pacific. The low numbers of NIS sampled in this study coincide with the low number of marine NIS known from Alaska, which suggests that an opportunity remains to promote awareness and management of the vector to limit NIS influx to the region. This may be particularly relevant for future scenarios of increased vessel traffic and ocean warming, which are likely to interact to increase establishment success of invaders from the south.

Since the beginning of the study, atmospheric CO sub(2) increased 18%, sea level rose 20 cm, and growing season temperature varied with approximately the same range as predicted for global warming in the 21st century. This review looks back at this study for clues about how the effects of rising sea level, temperature, and precipitation interact with high atmospheric CO sub(2) to alter the physiology of C3 and C4 photosynthetic species, carbon assimilation, evapotranspiration, plant and ecosystem nitrogen, and distribution of plant communities in this brackish wetland. Rising sea level caused a shift to higher elevations in the Scirpus olneyi C3 populations on the wetland, displacing the Spartina patens C4 populations. Elevated CO sub(2) stimulated carbon assimilation in the Scirpus C3 species measured by increased shoot and root density and biomass, net ecosystem production, dissolved organic and inorganic carbon, and methane production. But elevated CO sub(2) also decreased biomass of the grass, S. patens C4. The elevated CO sub(2) treatment reduced tissue nitrogen concentration in shoots, roots, and total canopy nitrogen, which was associated with reduced ecosystem respiration. Net ecosystem production was mediated by precipitation through soil salinity: high salinity reduced the CO sub(2) effect on net ecosystem production, which was zero in years of severe drought. The elevated CO sub(2) stimulation of shoot density in the Scirpus C3 species was sustained throughout the 28 years of the study. Results from this study suggest that rising CO sub(2) can add substantial amounts of carbon to ecosystems through stimulation of carbon assimilation, increased root exudates to supply nitrogen fixation, reduced dark respiration, and improved water and nitrogen use efficiency.

2014-102344 AB - We present a new empirical constraint on the rate of breakdown of large ejecta blocks on the Moon based on observations from the Lunar Reconnaissance Orbiter (LRO) Diviner thermal radiometer. We find that the rockiness of fresh crater ejecta can be quantified using the Diviner-derived rock abundance data set, and we present a strong inverse correlation between the 95 (super th) percentile value of the ejecta rock abundance (RA (sub 95/5) ) and crater age. For nine craters with published model ages derived from crater counts on their continuous ejecta, RA (sub 95/5) decreases with crater age, as (age [m.y.]) (super -0.46) . This result implies shorter rock survival times than predicted based on downward extrapolation of 100 m crater size-frequency distributions, and represents a new empirical constraint on the rate of comminution of large rocks not previously analyzed experimentally or through direct observation. In addition, our result provides a new method for dating young lunar craters.

Periodic pressurization controls explosion timing, which nearly always occurs at peak inflation, as detected with tiltmeters. Tilt cycles in January 2012 reveal regular 26 + or - 6 min inflation/deflation cycles corresponding to at least approximately 10 (super 1) kg/s of gas fluxing the system. Very long period (VLP) earthquakes presage explosions and occur during cycles when inflation rates are most rapid. VLPs locate approximately 300 m below the vent and indicate mobilization of volatiles, which ascend at approximately 50 m/s. Rapid gas ascent feeds pyroclast-laden eruptions lasting several minutes and rising to approximately 1 km. VLPs are not observed during less rapid inflation episodes; instead, gas vents passively through the conduit producing no infrasound and no explosion. These observations intimate that steady gas exsolution and accumulation in shallow reservoirs may drive inflation cycles at open-vent silicic volcanoes. Abstract Copyright (2014), .

The (+5.25,-3.02) field also includes observations of the bulge globular cluster NGC 6553. The results are based on high-resolution (R approximately 20,000), high signal-to-noise ration (S/N > or = 70) FLAMES-GIRAFFE spectra obtained through the European Southern Observatory archive. However, we only selected a subset of the original observations that included spectra with both high S/N and that did not show strong TiO absorption bands. This work extends previous analyses of this data set beyond Fe and the alpha -elements Mg, Si, Ca, and Ti. While we find reasonable agreement with past work, the data presented here indicate that the bulge may exhibit a different chemical composition than the local thick disk, especially at [Fe/H] > or = -0.5. In particular, the bulge [alpha /Fe] ratios may remain enhanced to a slightly higher [Fe/H] than the thick disk, and the Fe-peak elements Co, Ni, and Cu appear enhanced compared to the disk. There is also some evidence that the [Na/Fe] (but not [Al/Fe]) trends between the bulge and local disk may be different at low and high metallicity. We also find that the velocity dispersion decreases as a function of increasing [Fe/H] for both fields, and do not detect any significant cold, high-velocity populations. A comparison with chemical enrichment models indicates that a significant fraction of hypernovae may be required to explain the bulge abundance trends, and that initial mass functions that are steep, top-heavy (and do not include strong outflow), or truncated to avoid including contributions from stars >40 M (sub �) are ruled out, in particular because of disagreement with the Fe-peak abundance data. For most elements, the NGC 6553 stars exhibit abundance trends nearly identical to comparable metallicity bulge field stars. However, the star-to-star scatter and mean [Na/Fe] ratios appear higher in the cluster, perhaps indicating additional self-enrichment. Copyright (Copyright) 2014. The American Astronomical Society.

The calcareous permineralised fossils, which contain Teredolites borings, occur in erosive-based pebbly conglomerate lenses, interpreted as tidally influenced fluvial channels. All specimens show tile cells characteristic of many clades of the diverse and widespread family Malvaceae sensu APG III. Fossils were identified, more precisely, through searches of the Insidewood Database, and detailed study of comparative extant material. Two novel types of fossil wood occur: (1) Guazumaoxylon miocenica gen. et sp. nov shows paratracheal axial parenchyma with a broad-sheath to winged-aliform distribution combined with intermediate-type tile cells, similar to tropical South American species of Guazuma (subfamily Byttnerioideae) and (2) Periplanetoxylon panamense gen. et sp. nov shows apotracheal axial parenchyma in irregular to regular bands > 3 cells wide combined with Pterospermum-type tile cells, similar to tropical South American species of Pentaplaris (subfamily Malvoideae). The occurrence of fossils showing similarities to extant South American taxa in the Miocene of Panama is of palaeogeographic significance, suggesting intercontinental exchange of tree species at least ten million years before the traditional date for the final closure of the Panama Isthmus.

For example, recently, there has been a debate around the role of 'genomic islands of divergence' (i.e. blocks of outlier loci) in facilitating the process of speciation-with-gene-flow. The Swainson's thrush, Catharus ustulatus, is a migratory songbird with two genetically distinct subspecies that differ in a number of traits known to be involved in reproductive isolation in birds (plumage coloration, song and migratory behaviour), despite contemporary gene flow along a secondary contact zone. Here, we use RAD-PE sequencing to test emerging hypotheses about the process of divergence at the level of the genome and identify genes and gene regions involved in differentiation in this migratory songbird. Our analyses revealed distinct genomic islands on 15 of the 23 chromosomes and an accelerated rate of divergence on the Z chromosome, one of the avian sex chromosomes. Further, an analysis of loci linked to traits known to be involved in reproductive isolation in songbirds showed that genes linked to migration are significantly more differentiated than expected by chance, but that these genes lie primarily outside the genomic islands. Overall, our analysis supports the idea that genes linked to migration play an important role in divergence in migratory songbirds, but we find no compelling evidence that the observed genomic islands are facilitating adaptive divergence in migratory behaviour.

However, diagenetic processes that occur after sedimentation can systematically alter the primary isotopic signal recorded in sedimentary organic matter and must be accounted for in order to detect changes in the delta (super 15) N of nitrogen inputs to the sediment surface. Here we present a null model that estimates the diagenetic effect on sedimentary lake delta (super 15) N records. The model was tested using lake sediment cores from relatively pristine alpine lakes in the Wind River and Teton Ranges of Wyoming, USA. Model-inferred increases in productivity were tested against independent productivity proxies (diatom accumulation rates and the planktonic to benthic ratio), and inferred changes in anthropogenic nitrogen contribution were validated with records of atmospheric nitrogen deposition from the nearby Fremont Glacier, Wyoming. Diagenetic overprinting significantly altered sediment delta (super 15) N profiles, and the degree of alteration was not constant through time. Of the cores analyzed, approximately 30-70% of the variability can be explained by diagenesis alone, with the remainder explained by either a change in productivity or a change in the isotopic composition of the source material. Our null model of isotopic fractionation proved to be successful at separating the diagenetic overprinting from other causes of isotopic shifts, thereby providing environmental scientists with an analytical tool to partition the effects of diagenesis and environmental change on sedimentary delta (super 15) N values.

This article partially fills that gap by documenting the stratigraphy, architecture and palaeobotany of the Lower Pennsylvanian Boss Point Formation of Atlantic Canada, which contains some of the Earth's earliest accumulations of large woody debris. Braided-fluvial systems occupied channel belts of varied scale within valleys several tens of metres deep and more than 12 km wide, and their deposits predominantly consist of sandy and gravelly bedforms with subordinate accretionary macroforms, high flow-strength sand sheets and rippled abandonment facies. Discrete accumulations of clastic detritus and woody debris are up to 6 m thick and constitute at least 18% of the in-channel deposits; they represent lags at the base of large and small channels, fills of minor channels and sandy macroforms that developed in central positions in the upper parts of channel fills. Sandstones with roots and other remnants of in situ vegetation demonstrate that vegetated islands were present, and the abundance of discrete channel fills suggests that the formation represents an anabranching, island-braided sandbed river, the earliest example documented to date. Although some sphenopsid and lycopsid remains are present, most woody fragments are derived from cordaitalean trees, and the evolution of this group late in the Mississippian is inferred to have exerted a significant influence on fluvial morphodynamic patterns. The formation records a landscape in which active channel belts alternated with well-drained floodplains colonized by dense, mature forests and local patches of pioneering, disturbance-tolerant vegetation. Lakes and poorly drained floodplains dominated by carbonate and organic deposition, respectively, were also present. A large supply of woody debris triggered channel blockage and avulsion, and active channel margins and islands within the channel belts were initially colonized by pioneer vegetation and subsequently stabilized by large trees. A similar alternation of stable and unstable conditions is observed in modern braided rivers actively influenced by vegetation.

Consequently, interpretations of the Miocene ostracode assemblages must be supplemented using evidence from better documented taxa. Benthic foraminifera in samples from the Lower to Middle Miocene Brasso Formation at Brasso Village, Trinidad, have previously been used to distinguish three sample groupings (Beneath, Within and Above) around an oxygen minimum zone (OMZ), this being a layer of water within which dissolved oxygen concentrations can be as low as 0.1-1.0 mL/L. Using these same samples and the foraminiferal assemblage demarcations relative to the OMZ, this paper examines the associated and rich ostracode fauna of the Brasso Formation. The mean recovery of ostracode valves per sample was approximately three times greater in the Within OMZ sample group than in either of the Beneath OMZ or Above OMZ groups, perhaps reflecting the exclusion of macro-predators from within the OMZ. Individual rarefaction of species richness S to N = 300 valves was conducted for each sample group. This showed that S did not differ between the sample groups, ranging from 22.4 to 24.8. We used all ostracode species to model group separation. Based upon the Mahalanobis' criterion, we obtained significant group separation using a model with four taxa: Munseyella ex gr. minuta, Argilloecia posterotruncata, Munseyella sp. and Xestoleberis sp., while a fifth, Argilloecia spp., provided a significant but minor increase in separation probabilities over all groups. The two most abundant species (Bradleya sp., Gangamocytheridea reticulata) were thus not the best species for detecting the OMZ. Platycopid ostracodes of the genus Cytherella were found throughout the section, rather than concentrated within the OMZ, which contradicts the Platycopid Signal Hypothesis that OMZs are characterized by platycopid dominance. The total distribution and turnover of both ostracodal and foraminiferal assemblages were compared and contrasted quantitatively using a total assemblage turnover index (ATI) and the paleoenvironmental importance evaluated. The correlated between-sample ATI is for both groups lowest within the OMZ. Abstract Copyright (2014) Elsevier, B.V.

Evidence of fires in ancient forests, such as fossil charcoal (fusain), is well known to paleontologists and has been reported in geologic formations dating back to the Late Devonian. We describe what we conclude is a fire scar on a fossil tree trunk from the Late Triassic Chinle Formation of southeastern Utah ( approximately 200-225 Ma). The external features of the prehistoric scar match those of modern fire scars better than those of scars created by other kinds of wounding events. The fossil specimen also exhibits a number of changes in wood anatomy similar to those reported in modern fire-scarred trees, including a band of very small tracheids that indicate growth suppression immediately associated with the scarring event; an area with a tangential row of probable traumatic resin ducts; and a significant increase in tracheid size following the scarring event that indicates a growth release. No fire scar resembling those in modern trees has previously been described in petrified wood as far as we can determine. The presence of a fire scar not only provides further evidence of ancient fires, but also shows that at least some individual trees survived them, indicating that fire could have been an ecological and evolutionary force in forests at least as early as the Late Triassic.

Rietveld refinements revealed two obvious phase changes, at approximately 450 and approximately 950 K, corresponding to the dehydration of chalcophanite followed by transformation to a spinel structure (Mn-hetaerolite). Only small changes were observed in the chalcophanite unit cell from RT to approximately 438 K; the volume increased by approximately 0.8%, mostly caused by thermal expansion of approximately 0.5% along c. Above approximately 427 K, the interlayer water molecules were lost, resulting in a collapse of the interlayer spacing from approximately 7 to approximately 4.8 Aa. The newly formed anhydrous phase (ZnMn (sub 3) O (sub 7) ) retained chalcophanite's R3 space group and a dimension, but the c dimension decreased from approximately 21 to 14.3 Aa, and the Zn coordination changed from octahedral to tetrahedral. Above approximately 775 K the anhydrous chalcophanite began to transform to a spinel structure, corresponding to a Mn-rich hetaerolite [(Zn (sub 0.75) Mn (super 2+) (sub 0.25) )Mn (sub 2) (super 3+) O (sub 4) ]. By approximately 973 K the transformation was complete. The diffraction patterns did not show a significant increase in background during the transformation, indicating that the reaction did not involve transient amorphization. The phase change was likely triggered by loss of 1.25 of seven O atoms in the original anhydrous chalcophanite structure with a corresponding reduction of Mn (super 4+) to Mn (super 3+) and Mn (super 2+) .

This hypothesis has received numerous critiques, but little objective testing, either of cultural or genetic evidence. We contest the assertion that there is NO genetic evidence to support this hypothesis, and detail the published evidence, consistent with a pre-Columbian western Eurasian origin for some founding genetic markers, specifically mtDNA X2a, and some autosomal influence, found in ancient and modern Native American populations. The possibility that the inferred pre-Columbian western autosomal influence came more directly than through Siberia is not even considered in such studies. The mtDNA X2a evidence is more consistent with the Atlantic route and dates suggested by the Solutrean hypothesis and is more parsimonious than the assumption of a single Beringian entry, that assumes retrograde extinction of X in East Eurasia.

A critical re-appraisal of ancient DNA and geometric morphometrics AN - 1629336878; 4622544 AB - We challenge the claim by Krause-Kyora et al. (2013) that there were domestic pigs at Mesolithic sites in northern Germany. A small number of animals from Rosenhof and Poel have ancient DNA and geometric morphometric signatures elsewhere associated with domestic animals. At this time Neolithic farming settlements were present 150km to the south, but the Mesolithic specimens are, however, metrically wild boar, much larger than domestic pigs, and cannot be domestic individuals acquired from the farmers. A more likely explanation for these 'domestic' traits is that animals that escaped from farmers' pig herds interbred with local wild boar. Their descendants were morphologically and behaviourally wild, and were shot by Mesolithic foragers in the course of normal hunts. Their presence at Mesolithic sites is not a precursor to agriculture. Reprinted by permission of Routledge, Taylor and Francis Ltd.

Three cores were collected beneath floating fish-cage sites, two (S43 and S40) from the lagoon and one (S9A) from the estuary. The delta (super 13) C and delta (super 15) N signatures of core sediment indicate terrestrial sources for organic matter, including mangrove vegetation, throughout the cores. Percent carbon, percent nitrogen, and percent mud increase up core throughout S43. In S40, a similar up-core increase reverses, possibly related to the northward migration of an inlet to a more proximal position. In core S9A a similar reversal in these measurements corresponds to recent abandonment of fish cages at this location. Foraminiferal assemblages in cores S43 and S40 are dominated by calcareous taxa, in particular Ammonia aff. A. aoteana and Rosalina globularis. Agglutinated specimens, particularly of Ammobaculites exiguus, increase in abundance near the top of S43 and S40, likely in response to an increase in organic matter. Core S9A contains only agglutinated foraminifera, with Trochammina amnicola, Ammotium directum, Am. exiguus, and Miliammina fusca as the most abundant species. Foraminiferal assemblages do not change at sharp boundaries between sand and mud units in S9A, where T. amnicola dominates assemblages throughout the core except in the uppermost 4 cm. This is likely due to taphonomic loss of the delicate M. fusca down core. The percent of live specimens is relatively low in all three cores. The densities of dead foraminifera at S43 and S40 are extremely high at the base of the cores (i.e., at the onset of aquaculture) and near the surface of S40. These high densities are attributed to a baffling effect created by the fish cages as tidal currents transport sediments northwards in the lagoon. Aquaculture has affected organic-matter content, sediment characteristics, and foraminiferal distributions in the SEL. However, rapid return (probably within one-three years) to pre-aquaculture conditions after the abandonment of S9A and a slower return to pre-aquaculture conditions in S40 suggest that environmental health of the SEL is not overly compromised by the current scale of floating fish-cage aquaculture, particularly where significant tidal flushing occurs.

Two currently active floating fish-cage complexes, SET11-S43 and SET11-S40, are located in the semi-enclosed Setiu lagoon, within four km of an inlet connecting to the South China Sea. The sampling areas experience salinities in the 20s, and sediments have mixed agglutinated and calcareous foraminiferal [total] assemblages, generally dominated by Ammonia aff. A. aoteana and Ammobaculites exiguus. The majority of live foraminifera at these sites belong to agglutinated species; percent of live specimens is greater around the SET11-S43 fish-cage complex, likely related to the presence of aquaculture-related organic-rich mud. Percent agglutinated specimens in total assemblages (live + dead) decrease towards the inlet as total assemblage density and diversity increase due to increased salinity. At a recently (1-3 years) abandoned fish-cage complex, SET11-S9A, located in a low salinity (<5) estuarine setting, Miliammina fusca and Am. exiguus dominate total assemblages. Surface-sediment grain-size data indicate that fish-cage-related organic-rich mud underlies SET11-S43 and extends tens of meters to the north with a surrounding sandier substrate, typical of most of the Setiu estuary and lagoon system. SET11-S40 is underlain by generally sandy sediment; organic-rich mud characterizes the lagoon immediately to the north of this fish-cage complex. Percent carbon and nitrogen in sediment exhibit distributional patterns that strongly correlate with the distribution of fish-cage mud. Greater amounts of mud, carbon, and nitrogen in sediment are found to the north of the active lagoonal fish-cage complexes. The delta (super 13) C and delta (super 13) N signatures of the organic matter in this area are attributed to input from the surrounding mangrove forest, whereas their distribution is a result of the interaction of tidal currents with the physical presence of fish-farm complexes. The environmental influence of the active fish cages at lagoonal site SET11-S40 is minimal as a result of the flushing effects of tidal currents from a nearby inlet. Further north at the SET11-S43 lagoonal fish-cage complex, which receives less marine influence (lower salinity and reduced tidal currents), organic-rich mud has accumulated beneath and to the north of the complex. Foraminiferal and sedimentological data from abandoned estuarine fish-farm complex SET11-S9A are indistinguishable from those of adjacent estuarine sites indicating a rapid return to pre-fish-farm conditions following abandonment.

AN - 1613952457; 25078384 AB - Organisms have diverse adaptations for balancing dietary nutrients, but often face trade-offs between ingesting nutrients and toxins in food. While extremely omnivorous cockroaches would seem excluded from such dietary trade-offs, German cockroaches (Blattella germanica) in multiple populations have rapidly evolved a unique dietary specialization - an aversion to glucose, the phagostimulant in toxic baits used for pest control. We used factorial feeding experiments within the geometric framework to test whether glucose-averse (GA) cockroaches with limited access to this critical metabolic fuel have compensatory behavioural and physiological strategies for meeting nutritional requirements. GA cockroaches had severely constrained intake, fat and N mass, and performance on glucose-based diets relative to wild-type (WT) cockroaches and did not appear to exhibit digestive strategies for retaining undereaten nutrients. However, a GA × WT 'hybrid' had lower glucose aversion than GA and greater access to macronutrients within glucose-based diets - while still having lower intake and survival than WT. Given these intermediate foraging constraints, hybrids may be a reservoir for this maladaptive trait in the absence of positive selection and may account for the rapid evolution of this trait following bait application. © 2014 European Society For Evolutionary Biology.

Here we propose leaf vein density as a new tool to interpret fossil angiosperm life form, and in particular to trace the emergence of angiosperms as members of the canopy. Angiosperm leaf vein density was analyzed in two tropical forests and one temperate forest. Comparisons of vein density between canopy and understory plants showed that vein density variation mainly reflected the position of the leaf in the canopy, independent of ecological strategy (shade tolerant versus sun demanding), phylogenetic position, and site (tropical versus temperate). Vein density values of a standing forest were reflected in its leaf litter, suggesting that fossil leaf assemblages are representative of past forest ecosystems. Comparison of vein density distributions of Cretaceous-Paleocene paleofloras (132.35-58.0 Ma) to those of a modern tropical leaf litter assemblage suggests that angiosperms emerged in forest canopies by at least 58 Ma.

It has been used in a number of studies for inferring palaeoseasonality. Here we present a revised version of the equation for the zs-MART proxy based on an appropriate regression analysis and an estimate of the error associated with predicted values. We use this improved version to recalculate data used in studies that have employed the zs-MART proxy and evaluate their conclusions in light of the revised estimates for seasonal regimes. In order to investigate trans-colony zooid-size profiles in zooid size, length and width, 1195 zooids from 40 transects through 19 fossil and Recent specimens of the malacostegine cheilostome bryozoan Acanthodesia were measured using a stereomicroscope with eyepiece graticule. The position of zooids within bifurcating rows of Acanthodesia colonies is found to influence zooid size, and this exemplifies potential problems for studies based on zooid-size transects and random sampling of zooids. Our demonstration that oscillatory signals in zooid size, possibly attributable to seasonal temperature regimes, can be detected whilst accounting for other sources of variation confirms that a more sophisticated zs-MART proxy may prove useful for constraining parameters in ocean models addressing questions about past climate. However, such a proxy will require more parameters than originally described along with larger raw datasets. Abstract Copyright (2014) Elsevier, B.V.

We investigate the influence of methane on the thermodynamics and mechanics of the water mantle. We find that including methane in the water matrix introduces a new phase (filled ice), resulting in hotter planetary interiors. This effect renders the super-ionic and reticulating phases accessible to the lower ice mantle of relatively low-mass planets ( approximately 5 M (sub E) ) lacking a H/He atmosphere. We model the thermal and structural profile of the planetary crust and discuss five possible crustal regimes which depend on the surface temperature and heat flux. We demonstrate that the planetary crust can be conductive throughout or partly confined to the dissociation curve of methane clathrate hydrate. The formation of methane clathrate in the subsurface is shown to inhibit the formation of a subterranean ocean. This effect results in increased stresses on the lithosphere, making modes of ice plate tectonics possible. The dynamic character of the tectonic plates is analyzed and the ability of this tectonic mode to cool the planet is estimated. The icy tectonic plates are found to be faster than those on a silicate super-Earth. A mid-layer of low viscosity is found to exist between the lithosphere and the lower mantle. Its existence results in a large difference between ice mantle overturn timescales and resurfacing timescales. Resurfacing timescales are found to be 1 Ma for fast plates and 100 Ma for sluggish plates, depending on the viscosity profile and ice mass fraction. Melting beneath spreading centers is required in order to account for the planetary radiogenic heating. The melt fraction is quantified for the various tectonic solutions explored, ranging from a few percent for the fast and thin plates to total melting of the upwelled material for the thick and sluggish plates. Ice mantle dynamics is found to be important for assessing the composition of the atmosphere. We propose a mechanism for methane release into the atmosphere, where freshly exposed reservoirs of methane clathrate hydrate at the ridge dissociate under surface conditions. We formulate the relation between the outgassing flux and the tectonic mode dynamical characteristics. We give numerical estimates for the global outgassing rate of methane into the atmosphere. We find, for example, that for a 2 M (sub E) planet outgassing can release 10 (super 27) -10 (super 29) molecules s (super -1) of methane to the atmosphere. We suggest a qualitative explanation for how the same outgassing mechanism may result in either a stable or a runaway volatile release, depending on the specifics of a given planet. Finally, we integrate the global outgassing rate for a few cases and quantify how the surface atmospheric pressure of methane evolves over time. We find that methane is likely an important constituent of water planets' atmospheres. Copyright (Copyright) 2014. The American Astronomical Society. All rights reserved.

Lepidoptera are among tile organisms that have been shown to be strongly impacted by climate change, and their conservation presents challenges that are both unique and unprecedented. Varions studies bave sought to determine what ecological and life traits of Lepidoptera influence species' responses to climate change, and here I review the few studies that evaluate' such responses over a long period of time for a large number of species for common associations. Species with wider geographic distribution and less habitat specificity are generally considered less vulnerable to climate change, while those with opposite traits are deemed more vulnerable. The latter are more likely to change their phenology in response to climate change. Larval diet breadth and composition, overwintering stage, and adult activity period appear to be consistent predictors of changes in flight phenology. The knowledge of these traits for species of concern allows us to assess the implications of the possible phonological changes, and decide what can be done about those changes. Determining how phonological changes may affect current management or conservation practices and defining actions and priorities can be crucial for the success of a conservation plan.

Seasonal distributions of the isotopic data were assigned using a paleo-sea surface temperature model created by comparing modern sea surface temperatures (SST) to a fully profiled approximately 8,200-year-old shell. For 20 additional shells, we used two sampling strategies to compare season-of-harvest inferences and explore whether the Early Holocene site occupants were sedentary. Estimated season-of-harvest differed by 35% between the two sampling methods, corroborating recent isotope analysis of an 8,800-year-old shell midden on San Miguel Island. Shellfish appear to have been collected year-round at CA-SRI-666 from intertidal or subtidal water temperatures similar to modern SST in the vicinity of eastern Santa Rosa Island. The isotope results are consistent with other evidence from CA-SRI-666 that suggest that the site served as a residential base for relatively sedentary maritime people.

The main aims were (1) to characterize the evolution of molecular gas in circumstellar disks using L (sub IR) /L (sub *) values as a proxy of disk dust evolution, and (2) to identify new gas-rich disk systems suitable for detailed study with ALMA. About 60% of the sample (31 systems) have L (sub IR) /L (sub *) > 0.01, typical of T Tauri or Herbig AeBe stars, and the rest (21 systems) have L (sub IR) /L (sub *) 0.01. However, the spectra of only four of the newly detected systems appear free of contamination from background or foreground emission from molecular clouds. These include the early-type stars HD 104237 (A4/5V, 116 pc) and HD 98922 (A2 III, 507 pc, as determined in this work), where our observations reveal the presence of CO-rich circumstellar disks for the first time. Of the other detected sources, many could harbor gaseous circumstellar disks, but our data are inconclusive. For these two newly discovered gas-rich disks, we present radiative transfer models that simultaneously reproduce their spectral energy distributions and the (super 12) CO(3-2) line profiles. For both of these systems, the data are fit well by geometrically flat disks, placing them in the small class of non-flaring disks with significant molecular gas reservoirs.

However, the small size of many passerines has traditionally limited the tools available to track populations and as a result, restricted our ability to study how reproductive isolation might occur across a divide. Here, we integrate multiple approaches by using genetic, geolocator, and morphological data to investigate a migratory divide in hermit thrushes (Catharus guttatus). First, high genetic divergence between migratory groups indicates the divide is a region of secondary contact between historically isolated populations. Second, despite low sample sizes, geolocators reveal dramatic differences in overwintering locations and migratory distance of individuals from either side of the divide. Third, a diagnostic genetic marker that proved useful for tracking a key population suggests a likely intermediate nonbreeding location of birds from the hybrid zone. This finding, combined with lower return rates from this region, is consistent with comparatively lower fitness of hybrids, which is possibly due to this intermediate migration pattern. We discuss our results in the context of reproductive isolating mechanisms associated with migration patterns that have long been hypothesized to promote divergence across migratory divides. Migratory divides, the boundary between adjacent bird populations that migrate in different directions, are of considerable interest to evolutionary biologists because of their alleged role in promoting reproductive divergence and speciation.

Following the rejection of the proposed GSSP for the base of the Albian Stage (based on the first occurrence of the ammonite Leymeriellla tardefurcata in the section at Le Pillart, Tartonne, Alpes-de-Haute Provence), we re-visit the Pre-Guittard section. A new candidate GSSP defined by the first occurrence of the planktonic foraminifera Microhedbergella renilaevis Huber and Leckie, 2011 is here proposed. This first occurrence is placed in a 100 m section with 28 secondary markers, including calcareous nannofossils, planktonic foraminifera, palynomorphs, an inoceramid bivalve, ammonites, stable carbon isotopes, and local marker beds. The outcrop fulfills most of the physical criteria required of a Global Stratotype Section and Point. Abstract Copyright (2014) Elsevier, B.V.

The phylogenetic position of the first published specimen, a partial braincase designated as the holotype of Itemirus medullaris Kurzanov, 1976, has long been contentious. Our examination of the specimen supports its attribution to Dromaeosauridae. Additional, mostly well-preserved dromaeosaurid skeletal remains from the Bissekty Formation include cranial bones, teeth, vertebrae, and some podial elements. They are tentatively referred to the same taxon, Itemirus medullaris, and establish the presence of dromaeosaurid paravians in present-day Central Asia during the Turonian.

However, differential species preservation and collection (including body-size bias) in both modern and fossil death assemblages may still skew the representation of other important ecological characteristics. Here, we move beyond live-dead taxonomic fidelity and focus on the recovery of functional ecology (how species interact with their ecosystem) at the community level for a diverse non-volant mammal community (87 species; Amboseli, Kenya). We use published literature to characterize species, using four functional traits and their associated categorical attributes (i) dietary mode (11 attributes; e.g., browser, grazer), (ii) preferred feeding habitat (16 attributes; e.g., grassland, woodland), (iii) preferred sheltering habitat (17 attributes; e.g., grassland, underground cavity), and (iv) activity time (7 attributes; e.g., diurnal, nocturnal, nocturnally dominated crepuscular). For each functional ecological trait we compare the death assemblage's recovered richness and abundance structure of constituent functional attributes with those of the source community, using Jaccard similarity, Spearman's rho, and the Probability of Interspecific Encounter (evenness). We use Monte Carlo simulations to evaluate whether these empirical comparisons are significantly different from expectations calculated from randomized sampling of species from the source community. Results indicate that although the Amboseli death assemblage is significantly overrepresented by large-bodied species relative to the Amboseli source community, it captures many functional dimensions of the ecosystem within expectations of a randomized collection of species. Additional resampling simulations and logistic regressions further illustrate that the size bias inherent to the Amboseli death assemblage is not a major driver of deviations between the functional ecological properties of the death assemblage and its source community. Finally, the Amboseli death assemblage also enhances our understanding of the mammal community by adding nine species and two functional attributes previously unknown from the ecosystem.

Experiments comprise heated and ambient temperature 20 mu m talc powder turbulently suspended in air to form density currents within an unobstructed 8.5 X 6 X 2.6-m chamber. Comparisons of Richardson, thermal Richardson, Froude, Stokes, and settling numbers and buoyant thermal to kinetic energy densities show good agreement between experimental currents and dilute PDCs. The experimental Reynolds numbers are lower than those of PDCs, but the experiments are fully turbulent; thus, the large-scale dynamics are similar between the two systems. High-frequency, simultaneous observation in three orthogonal planes shows that the currents behave very differently than previous 2D (i.e., confined) currents. Specifically, whereas ambient temperature currents show radial dispersal patterns, buoyancy reversal, and liftoff of heated currents focuses dispersal along narrow axes beneath the rising plumes. The aspect ratios, defined as the current length divided by a characteristic width, are typically 2.5-3.5 in heated currents and 1.5-2.5 in ambient temperature currents, reflecting differences in dispersal between the two types of currents. Mechanisms of air entrainment differ greatly between the two currents: entrainment occurs primarily behind the heads and through the upper margins of ambient temperature currents, but heated currents entrain air through their lateral margins. That lateral entrainment is much more efficient than the vertical entrainment, >0.5 compared to approximately 0.1, where entrainment is defined as the ratio of cross-stream to streamwise velocity. These experiments suggest that generation of coignimbrite plumes should focus PDCs along narrow transport axes, resulting in elongate rather than radial deposits.

AN - 1623261351; 2014-089003 AB - In order to link infrared observations of dust formed during planet formation in debris disks to mid-infrared spectroscopic data of planetary materials from differentiated terrestrial and asteroidal bodies, we obtained absorption spectra of a representative suite of terrestrial crustal and mantle materials, and of typical martian meteorites. A series of debris disk spectra characterized by a strong feature in the 9.0-9.5 mu m range (HD23514, HD15407a, HD172555 and HD165014), is comparable to materials that underwent shock, collision or high temperature events. These are amorphous materials such as tektites, SiO (sub 2) -glass, obsidian, and highly shocked shergottites as well as inclusions from mesosiderites (group A). A second group (BD+20307, Beta Pictoris, HD145263, ID8, HD113766, HD69830, P1121, and Eta Corvi) have strong pyroxene and olivine bands in the 9-12 mu m range and is very similar to ultramafic rocks (e.g. harzburgite, dunite) (group B). This could indicate the occurrence of differentiated materials similar to those in our Solar System in these other systems. However, mixing of projectile and target material, as well as that of crustal and mantle material has to be taken into account in large scale events like hit-and-run and giant collisions or even large-scale planetary impacts. This could explain the olivine-dominated dust of group B. The crustal-type material of group A would possibly require the stripping of upper layers by grazing-style hit-and run encounters or high energy events like evaporation/condensation in giant collisions. In tidal disruptions or the involvement of predominantly icy/water bodies the resulting mineral dust would originate mainly in one of the involved planetesimals. This could allow attributing the observed composition to a specific body (such as e.g. Eta Corvi).

Ant social parasites and their rus hosts are often close relatives (Emery's rule), and two main hypotheses compete to explain the parasites' evolutionary origins: (1) the interspecific hypothesis proposes an allopathe speciation scenario for the parasite, whereas (2) the intraspecific hypothesis postulates that the parasite evolves directly from its host in sympatry [1-10]. Evidence in support of the intraspecific hypothesis has been accumulating (or for ants [3, 5, 7, 9-12], but sympatric speciation remains is controversial as a general speciation mechanism for inquiline parasites. Here we use molecular phylogenetics to assess whether the socially parasitic fungus-growing ant Mycocepurus castrator speciated from its host Mycocepurus goeldii in sympatry. Based on differing patterns of relationship in mitochondrial and individual nuclear genes, we conclude that host and parasite occupy a temporal window in which lineage sorting has taken place in the mitochondrial genes but not yet in the nuclear alleles. We infer that the host originated first and that the parasite originated subsequently from a subset of the host species' populations, providing empirical support for the hypothesis that inquiline parasites can evolve reproductive isolation while living sympatrically with their hosts.

The bird that made these tracks had very long legs but relatively short toes and was probably somewhat smaller than modern stilts (Himantopus). There was a vestigial hind toe and the feet were webbed, but the webbing was reduced more than in Recurvirostra or Cladorhynchus, but not nearly as much as in Himantopus. This may constitute the oldest evidence yet found of a recurvirostid-like bird, although the family probably originated even earlier if it gave rise to flamingos (Phoenicopteridae), which were already in existence by the early and middle Eocene.

Data were gathered from 496 extant and fossil Cupuladria specimens ranging in age from early Miocene to Recent and distributed from the Caribbean to tropical eastern Pacific. A first series of discriminant analyses distinguished three morphological groups: Cupuladria with vicarious avicularia, Cupuladria without vicarious avicularia, and Discoporella. Further discriminant analyses identified 17 species of Cupuladria. Cladistic analyses of these three groups yielded four equally parsimonious trees. All of the consensus trees exhibited the same topology, dividing the 25 tropical American cupuladriids into four distinct monophyletic clades, including Discoporella, and are consistent with previous molecular phylogenies except that there are no molecular data for the C (sub V2) clade. Diversification of species was higher in the C (sub V1) and C (sub V2) clades than C (sub NV) clade, and involved mostly Caribbean species. Cupuladria with vicarious clade 1 (C (sub V1) ) includes: C. monotrema, C. pacificiensis, C. exfragminis, C. cheethami, C. biporosa, and four new species: C. pervagata, C. floridensis, C. colonensis and C. dominicana. Cupuladria with vicarious clade 2 (C (sub V2) ) includes: C. multesima, C. incognita, and three new species C. collyrida, C. veracruxiensis and C. planissima. Cupuladria clade without vicarious (C (sub NV) ) includes: C. surinamensis, C. panamensis, and one new species C. gigas. The stratigraphic occurrence of species is consistent with cladogram topology within clades. However hypothesized cladistic relations among clades are the reverse of their stratigraphic occurrence with younger clade C (sub NV) appearing as the hypothetical ancestor of the two older clades C (sub V1) and C (sub V2) . More extensive collections of early to middle Miocene specimens of Cupuladria and Discoporella will be required to resolve this apparent paradox.

Geochemical records of tropical sea-surface temperatures (SSTs) from the PETM are rare and are typically affected by post-depositional diagenesis. To circumvent this issue, we have analyzed oxygen isotope ratios (delta (super 18) O) of single specimens of exceptionally well-preserved planktonic foraminifera from the PETM in Tanzania ( approximately 19 degrees S paleolatitude), which yield extremely low delta (super 18) O, down to 3 degrees C during the PETM and may have exceeded 40 degrees C. Calcareous plankton are absent from a large part of the Tanzania PETM record; extreme environmental change may have temporarily caused foraminiferal exclusion.

The paper is in four parts. In Part 1, we explain how the analysis of human remains forms an important component of archaeological research, and why looting activity at burial sites prejudice this research. In Part 2 we review the existing and relevant archaeological, ethnographic and criminological literature on the subject while in Part 3 we describe our own research into the online trade in human remains, both licit and illicit. To assess the current global prevalence and distribution of public and private dealers in human remains, keyword searches on common search engines (Google, Yahoo, Bing), and online sites like eBay and Amazon were conducted. In Part 4 we draw some conclusions about our research and point in particular to various policy and law reform issues which require further consideration and study.

We tested the hypotheses that seed dispersal is NDD, due to intraspecific competition for dispersers, and that this contributes to NDD of recruitment. We compared dispersal in the palm Attalea butyracea across a wide range of population density on Barro Colorado Island in Panama and assessed its consequences for seed distributions. We found that frugivore visitation, seed removal and dispersal distance all declined with population density of A. butyracea, demonstrating NDD of seed dispersal due to competition for dispersers. Furthermore, as population density increased, the distances of seeds from the nearest adult decreased, conspecific seed crowding increased and seedling recruitment success decreased, all patterns expected under poorer dispersal. Unexpectedly, however, our analyses showed that NDD of dispersal did not contribute substantially to these changes in the quality of the seed distribution; patterns with population density were dominated by effects due solely to increasing adult and seed density.

Sequence data of two low-copy nuclear (LCN) genes, phosphoenolpyruvate carboxylase 4 (Pepc4) and granule-bound starch synthase I (GBSSI), from 79 accessions of Sorghum plus Cleistachne sorghoides together with those from outgroups were used for maximum likelihood (ML) and Bayesian inference (BI) analyses. Bayesian dating based on three plastid DNA markers (ndhA intron, rpl32-trnL, and rps16 intron) was used to estimate the ages of major diversification events in Sorghum. The monophyly of Sorghum plus Cleistachne sorghoides (with the latter nested within Sorghum) was strongly supported by the Pepc4 data using BI analysis, and the monophyly of Sorghum was strongly supported by GBSSI data using both ML and BI analyses. Sorghum was divided into three clades in the Pepc4, GBSSI, and plastid phylograms: the subg. Sorghum lineage; the subg. Parasorghum and Stiposorghum lineage; and the subg. Chaetosorghum and Heterosorghum lineage. Two LCN homoeologous loci of Cleistachne sorghoides were first discovered in the same accession. Sorghum arundinaceum, S. bicolor, S. x drummondii, S. propinquum, and S. virgatum were closely related to S. x almum in the Pepc4, GBSSI, and plastid phylograms, suggesting that they may be potential genome donors to S. almum. Multiple LCN and plastid allelic variants have been identified in S. halepense of subg. Sorghum. The crown ages of Sorghum plus Cleistachne sorghoides and subg. Sorghum are estimated to be 12.7 million years ago (Mya) and 8.6 Mya, respectively. Molecular results support the recognition of three distinct subgenera in Sorghum: subg. Chaetosorghum with two sections, each with a single species, subg. Parasorghum with 17 species, and subg. Sorghum with nine species and we also provide a new nomenclatural combination, Sorghum sorghoides.

766147-17 AB - The broad palette of feather colours displayed by birds serves diverse biological functions, including communication and camouflage. Fossil feathers provide evidence that some avian colours, like black and brown melanins, have existed for at least 160 million years (Myr), but no traces of bright carotenoid pigments in ancient feathers have been reported. Insight into the evolutionary history of plumage carotenoids may instead be gained from living species. We visually surveyed modern birds for carotenoid-consistent plumage colours (present in 2956 of 9993 species). We then used high-performance liquid chromatography and Raman spectroscopy to chemically assess the family-level distribution of plumage carotenoids, confirming their presence in 95 of 236 extant bird families (only 36 family-level occurrences had been confirmed previously). Using our data for all modern birds, we modelled the evolutionary history of carotenoid-consistent plumage colours on recent supertrees. Results support multiple independent origins of carotenoid plumage pigmentation in 13 orders, including six orders without previous reports of plumage carotenoids. Based on time calibrations from the supertree, the number of avian families displaying plumage carotenoids increased throughout the Cenozoic, and most plumage carotenoid originations occurred after the Miocene Epoch (23 Myr). The earliest origination of plumage carotenoids was reconstructed within Passeriformes, during the Palaeocene Epoch (66-56 Myr), and not at the base of crown-lineage birds.

Distinctive characteristics of the proposed new species, W. gordoniae, include: overall habit; built up pseudoparenchymatous cortex that is composed of 2, and in localized sites up to 3, layers of cortical cells, with the outermost layer incomplete, composed of smaller, irregular-shaped cells; and spermatangial heads with 5-6 (-7) involucres, each consisting of a single elongate cell. Analyses of SSU sequences of specimens of Wrangelia from Puerto Rico further support the presence of four genetically distinct entities. In addition to numerous recent collections, a number of herbarium specimens from different Caribbean locales previously identified as "W. penicillata" are now recognized to be W. gordoniae. The new species is compared morphologically with other Wrangelia species that also have 5 whorl branchlets per segment and a cortex that partially or wholly covers their axes. A key to the tropical western Atlantic species of Wrangelia is provided.

We used Bayesian and maximum-likelihood phylogenetic reconstructions using mitochondrial [cytochrome c oxidase subunit I (COI) and ATP synthase 6 and 8 (ATPase 8/6)] and nuclear (RAG1 and rhodopsin) genes and extensive geographical sampling, together with molecular clock analyses and tests of biogeographical scenarios to assess the timing and mode of dispersal and diversification. Results: We identified high levels of phylogeographical structure, with a highly divergent lineage composed of individuals from western Atlantic Panama (Bocas), sister to all trans-Andean South American and Central American lineages. The Pacific slope of Panama showed surprisingly little genetic structure compared with the Atlantic slope. Molecular-clock and biogeographical analyses support two waves of colonization originating from South America: a first dispersal event in the late Miocene with the Bocas lineage as the only relict, and a second major colonization in the late Pliocene leading to the establishment of B. occidentalis in all central and eastern Panama drainages. The genetic structure of B. occidentalis over the Isthmian landscape reflects the progressive, complex and dynamic geological evolution of the region. Our results support multiple colonization events, with an ancient Miocene dispersal event followed by a recent rapid expansion in the late Pliocene, probably facilitated by the final closure of the Isthmus, which provided an important corridor.

Only at the Phoenix site do we find clear evidence of subsurface radar returns, mapping out an interface that may be the base of ground ice at depths of approximately 15-66 m across 2900 km (super 2) in the depression where the lander resides. At the Opportunity, Spirit, and candidate Curiosity sites, images and altimetry show layered materials tens to hundreds of meters thick extending tens to hundreds of kilometers laterally. These scales are well within SHARAD's resolution limits, so the lack of detections is attributable either to low density contrasts in layers of similar composition and internal structure or to signal attenuation within the shallowest layers. At each site, we use the radar return power to estimate surface roughness at scales of 10-100 m, a measure that is important for assessing physical properties, landing safety, and site trafficability. The strongest returns are found at the Opportunity site, indicating that Meridiani Planum is exceptionally smooth. Returns of moderate strength at the Spirit site reflect roughness more typical of Mars. Gale crater, Curiosity's ultimate destination, is the smoothest of the four proposed sites we examined, with Holden crater, Eberswalde crater, and Mawrth Vallis exhibiting progressively greater roughness.

We constructed six groups of Sphagnum microcosms (1 m 1 m) with three replicates. A factorial design with two planting methods (capitulum without stem and capitulum with stem) and three levels of nitrogen addition (0, 2, and 6 g N m super(-2) year super(-1)) were prepared. Changes in length, dry mass, and decomposition rates of Sphagnum were monitored over a growing season. The effect of N concentration on production varied for the different planting methods. Production of Sphagnum increased with N concentration in the capitulum without the stem treatment (-D) than in the with stem treatment (+D). Adding N affected the decomposition rate in both with and without stem treatments. Decomposition rate increased with added nitrogen. Planting without stems (-D) was an effective design for a high production and low decomposition of Sphagnum. Net primary production was 187-260 g m super(-2 )year super(-1) for dry mass and 15.5- 26.5 mm year super(-1) for length, whereas decomposition rates were 10.9-14.7 % mass loss per year. These values are comparable to those from natural bogs. The overall results indicate that constructing Sphagnum wetlands can be successfully employed as a greening technology in urban ecosystems, even in mid-latitudes.

Animal communication, likewise, often consists of signals containing stimuli processed by different senses [3-6]. Stimuli with different physical forms (i.e., from different sensory modalities) travel at different speeds [7]. As a consequence, multimodal stimuli simultaneously emitted at a source can arrive at a receiver at different times. Such differences in arrival time can provide unique information about the distance to the source [8, 9]. Male tungara frogs (Physalaemus pustulosus) call from ponds to attract females and to repel males. Production of the sound Incidentally creates ripples on the water surface, providing a multimodal cue [10]. We tested whether male frogs attend to distance-dependent cues created by a calling rival and whether their response depends on crossmodal comparisons. In a first experiment, we showed distance-dependent changes in vocal behavior: males responded more strongly with decreasing distance to a mimicked rival. In a second experiment, we showed that males can discriminate between relatively near and far rivals by using a combination of unimodal cues, specifically amplitude changes of sound and water waves, as well as crossmodal differences in arrival time. Our data reveal that animals can compare the arrival time of simultaneously emitted multimodal cues to obtain information on relative distance to a source. We speculate that communicative benefits from crossmodal comparison may have been an important driver of the evolution of elaborate multimodal displays [11, 12].

Niche models, competition, and distributions of South American mouse opossums AN - 1560129917; 20538028 AB - Based on our own empirical data and a literature review, we explore the possibility that biotic interactions, specifically competition, might be responsible for creating, and/or maintaining, geographic isolation. Ecological niche modeling was first used to test whether the distributions of 2 species of Neotropical marsupials (Marmosa robinsoni and M. xerophila) fit the predicted geographic pattern of competitive exclusion: one species predominates in areas environmentally suitable for both species along real contact zones. Secondly, we examined the connectivity among populations of each species, interpreted in the light of the niche models. The results show predominance of M. xerophila along its contact zone with M. robinsoni in the Peninsula de Paraguana in northwestern Venezuela. There, M. robinsoni has an extremely restricted distribution despite climatic conditions suitable for both species across the peninsula and its isthmus. The latter two results suggest that M. xerophila may be responsible for the geographic isolation of the peninsular populations of M. robinsoni with respect to other populations of the latter species in northwestern Venezuela. These results may represent an example of allopatry caused, or at least maintained, by competition. Our results and a review of numerous studies in which biotic interactions restrict species distributions (including at the continental scale) support a previously overlooked phenomenon: biotic interactions can isolate populations of a species. We propose 2 general mechanisms, intrusion and contraction, to classify allopatric conditions caused by various classes of biotic interactions. We present a necessary modification of the concept of ecological vicariance to include biotic interactions as possible vicariant agents regardless of whether genetic differentiation occurs or not.

For most mammal species, it is unknown how these factors contribute to sex differences in feeding, or how the development of males and females reflects these intraspecific feeding differences. We show changes in dietary composition, diversity, overlap, and foraging behavior throughout development in ring-tailed lemurs (Lemur catta) and test how the development of sex differences in feeding is related to female costs of reproduction and year-round resource partitioning. Sex differences in dietary composition were only present when females were lactating, but sex differences in other aspects of feeding, including dietary diversity, and relative time spent feeding and foraging, developed at or near the time of weaning. Sex difference in juveniles and subadults, when present, were similar to the differences found in adults. The low year-round dietary overlap and early differences in dietary diversity indicate that some resource partitioning may begin with young individuals and fluctuate throughout development. The major differences between males and females in dietary composition suggest that these larger changes in diet are closely tied to female reproductive state when females must shift their diet to meet energetic and nutritional requirements.

We sought to determine whether gender-specific exposure to vector habitats explains male-biased CL incidence in two human populations of central Amazonia. We compared the CL incidence in one population of field researchers (N = 166), with similar exposure for males and females, and one population of rural settlers (N = 646), where exposure is overall male-biased. We used a combination of questionnaires and clinical data to quantify CL cases, and modelled disease incidence in a Bayesian framework. There was a moderately higher incidence of CL among men than among women in both populations, but male bias decreased as exposure time increased. Disease incidence was overall higher among field researchers, suggesting that they are an important but understudied CL risk group. Our comparison of two contrasting populations provided epidemiological evidence that CL incidence can be male-biased even when exposure is comparable in both sexes.Original Abstract: La leishmaniose cutanee (LC) est plus frequemment rapportee chez les hommes que chez les femmes, cela peut etre du a l'exposition particuliere des hommes aux vecteurs de la LC, la resistance particuliere des femmes contre la maladie, ou les deux. Nous avons cherche a determiner si l'exposition specifique au sexe aux habitats des vecteurs explique l'incidence biaisee de la LC chez les hommes dans deux populations humaines du centre de l'Amazonie. Nous avons compare l'incidence de la LC dans une population de chercheurs sur le terrain (N = 166), avec une exposition similaire pour les hommes et les femmes a celle d'une population de colons ruraux (N = 646), chez laquelle l'exposition est globalement particuliere pour les hommes. Nous avons utilise une combinaison de questionnaires et des donnees cliniques pour quantifier les cas de LC et avons modelise l'incidence de la maladie dans un cadre bayesien. Il y avait une incidence moderement plus elevee de LC chez les hommes que chez les femmes dans les deux populations, mais la particularite masculine diminuait avec l'augmentation du temps d'exposition. L'incidence de la maladie etait globalement plus elevee chez les chercheurs sur le terrain, ce qui suggere qu'ils sont un groupe a risque important pour la LC, mais peu etudie. Notre comparaison de deux populations contrastees fourni la preuve epidemiologique que l'incidence de la LC peut etre liee au sexe masculin meme lorsque l'exposition est comparable entre les deux sexes. La leishmaniosis cutanea (LC) se reporta mas frecuentemente entre hombres que entre mujeres; esto podria deberse a una exposicion sesgada de los hombres a los vectores de la LC, a un sesgo en la resistencia femenina frente a la enfermedad, o a ambos. Hemos buscado determinar si la exposicion genero-especifica a los habitats vectoriales explican el sesgo masculino en la incidencia de LC en os poblaciones humanas de la Amazonia central. Hemos comparado la incidencia de LC en una poblacion de investigadores de campo (N = 166), con exposicion similar para hombres y mujeres, y una poblacion de habitantes rurales (N = 646), en donde la exposicion en general tiene un sesgo masculino. Hemos utilizado una combinacion de cuestionarios y datos clinicos para cuantificar casos de LC, y modelado la incidencia de enfermedad en un marco Bayesiano. Habia una incidencia moderadamente mayor de LC entre hombres que entre mujeres en ambas poblaciones, pero el sesgo masculino disminuia a medida que el tiempo de exposicion aumentaba.

AN - 1551023561; 25081595 AB - We study highly excited diskoid-like electronic states formed in the vicinity of charged and strongly polarizable diskotic nanostructures, such as circular graphene flakes. First, we study the nature of such extended states in a simple two-electron model. The two electrons are attached to a point-like nucleus with a charge 2+, where the material electron is forced to move within a 2D disk area centered at the nucleus, while the extended electron is free to move in 3D. Pronounced and complex correlations are revealed in the diskoid-like states. We also develop semiclassical one-electron models of such diskotic systems and explain how the one-electron and many-electron solutions are related.

While WNV incidence has been linked to environmental factors, particularly temperature and rainfall, little is known about how future climate change may affect the spread of the disease. Using available data on WNV infections in vectors and hosts collected from 2003-2011 and using a suite of 10 species distribution models, weighted according to their predictive performance, we modeled the incidence of WNV under current climate conditions at a continental scale. Models were found to accurately predict spatial patterns of WNV that were then used to examine how future climate may affect the spread of the disease. Predictions were accurate for cases of human WNV infection in the following year (2012), with areas reporting infections having significantly higher probability of presence as predicted by our models. Projected geographic distributions of WNV in North America under future climate for 2050 and 2080 show an expansion of suitable climate for the disease, driven by warmer temperatures and lower annual precipitation that will result in the exposure of new and naive host populations to the virus with potentially serious consequences. Our risk assessment identifies current and future hotspots of West Nile virus where mitigation efforts should be focused and presents an important new approach for monitoring vector-borne disease under climate change.

However, the Mexican Hat locality (ca. 65 Ma) in southeastern Montana, with a typical, low-diversity flora, uniquely exhibits high damage diversity on nearly all its host plants, when compared to all known local and regional early Paleocene sites. The same plant species show minimal damage elsewhere during the early Paleocene. We asked whether the high insect damage diversity at Mexican Hat was more likely related to the survival of Cretaceous insects from refugia or to an influx of novel Paleocene taxa. We compared damage on 1073 leaf fossils from Mexican Hat to over 9000 terminal Cretaceous leaf fossils from the Hell Creek Formation of nearby southwestern North Dakota and to over 9000 Paleocene leaf fossils from the Fort Union Formation in North Dakota, Montana, and Wyoming. We described the entire insect-feeding ichnofauna at Mexican Hat and focused our analysis on leaf mines because they are typically host-specialized and preserve a number of diagnostic morphological characters. Nine mine damage types attributable to three of the four orders of leaf-mining insects are found at Mexican Hat, six of them so far unique to the site. We found no evidence linking any of the diverse Hell Creek mines with those found at Mexican Hat, nor for the survival of any Cretaceous leaf miners over the K-Pg boundary regionally, even on well-sampled, surviving plant families. Overall, our results strongly relate the high damage diversity on the depauperate Mexican Hat flora to an influx of novel insect herbivores during the early Paleocene, possibly caused by a transient warming event and range expansion, and indicate drastic extinction rather than survivorship of Cretaceous insect taxa from refugia.

The mass of the planet was measured with a precision of around 30%, which was insufficient to constrain models of its internal structure and composition in detail. In addition to Kepler-10b, a second planet transiting the same star with a period of 45 days was statistically validated, but the radial velocities were only good enough to set an upper limit of 20 M (sub ⊕) for the mass of Kepler-10c. To improve the precision on the mass for planet b, the HARPS-N Collaboration decided to observe Kepler-10 intensively with the HARPS-N spectrograph on the Telescopio Nazionale Galileo on La Palma. In total, 148 high-quality radial-velocity measurements were obtained over two observing seasons. These new data allow us to improve the precision of the mass determination for Kepler-10b to 15%. With a mass of 3.33 + or - 0.49 M (sub ⊕) and an updated radius of (sub IMG .../ (super R (sub ⊕) , Kepler-10b has a density of 5.8 + or - 0.8 g cm (super -3) , very close to the value predicted by models with the same internal structure and composition as the Earth. We were also able to determine a mass for the 45-day period planet Kepler-10c, with an even better precision of 11%. With a mass of 17.2 + or - 1.9 M (sub ⊕) and radius of (sub IMG .../ (super R (sub ⊕) , Kepler-10c has a density of 7.1 + or - 1.0 g cm (super -3) . Kepler-10c appears to be the first strong evidence of a class of more massive solid planets with longer orbital periods. Copyright (Copyright) 2014. The American Astronomical Society.

Many features associated with Homo sapiens, including our large linear bodies, elongated hind limbs, large energy-expensive brains, reduced sexual dimorphism, increased carnivory, and unique life history traits, were once thought to have evolved near the origin of the genus in response to heightened aridity and open habitats in Africa. However, recent analyses of fossil, archaeological, and environmental data indicate that such traits did not arise as a single package. Instead, some arose substantially earlier and some later than previously thought. From approximately 2.5 to 1.5 million years ago, three lineages of early Homo evolved in a context of habitat instability and fragmentation on seasonal, intergenerational, and evolutionary time scales. These contexts gave a selective advantage to traits, such as dietary flexibility and larger body size, that facilitated survival in shifting environments.

We have spent 19.9 hr of observing time with channel 2 (4.5 mu m) of the Infrared Array Camera and detected the target within the 2sigma positional uncertainty ellipse. Using an asteroid thermophysical model and a model of nongravitational forces acting upon the object, we constrain the physical properties of 2011 MD, based on the measured flux density and available astrometry data. We estimate 2011 MD to be (6 (super +4) (sub -2) ) m in diameter with a geometric albedo of 0.3 (super .04) (sub 0.2) (uncertainties are 1sigma ). We find the asteroid's most probable bulk density to be (1.1 (super +0.7) (sub -0.5) ) g cm (super -3) , which implies a total mass of (50-350) t and a macroporosity of > or =65%, assuming a material bulk density typical of non-primitive meteorite materials. A high degree of macroporosity suggests that 2011 MD is a rubble-pile asteroid, the rotation of which is more likely to be retrograde than prograde. Copyright (Copyright) 2014.

On timescales from days to years, substantial changes occur in emission line profiles and line strengths. Our extensive time-domain spectroscopy suggests that the broad near-IR, optical, and far-uv emission lines, centered on the star, originate in a turbulent post-shock region and can undergo scattering by the overlying stellar wind as well as some absorption from infalling material. Stable absorption features appear in H alpha , apparently caused by an accreting column silhouetted in the stellar wind. Inflow of material onto the star is revealed by the near-IR He I 10830 A line, and its free-fall velocity correlates inversely with the strength of the post-shock emission, consistent with a dipole accretion model. However, the predictions of hydrogen line profiles based on accretion stream models are not well-matched by these observations. Evidence of an accelerating warm to hot stellar wind is shown by the near-IR He I line, and emission profiles of C II, C III, C IV, N V, and O VI. The outflow of material changes substantially in both speed and opacity in the yearly sampling of the near-IR He I line over a decade. Terminal outflow velocities that range from 200 km s super(-1) to almost 400 km s super(-1) in He I appear to be directly related to the amount of post-shock emission, giving evidence for an accretion-driven stellar wind. Calculations of the emission from realistic post-shock regions are needed.

We introduce a new solar activity proxy, based on nitrate (NO (sub 3) (super -) ) concentration from the Talos Dome ice core, East Antarctica. We also use a new algorithm for computing multiple-cross wavelet spectra in time-frequency space that is generalized for multiple time series (beyond two). Our results provide a new interpretive framework for relating Holocene solar activity variations on centennial to millennial timescales to co-varying climate proxies drawn from a widespread area around the globe. Climatic proxies used represent variation in the North Atlantic Ocean, Western Pacific Warm Pool, Southern Ocean and the East Asian monsoon regions. Our wavelet analysis identifies fundamental solar modes at 2300-yr (Hallstattzeit), 1000-yr (Eddy), and 500-yr (unnamed) periodicities, leaves open the possibility that the 1500-1800-yr cycle may either be fundamental or derived, and identifies intermediary derived cycles at 700-yr and 300-yr that may mark rectified responses of the Atlantic thermohaline circulation to external solar modulation and pacing. Dating uncertainties suggest that the 1500-yr and 1800-yr cycles described in the literature may represent either the same or two separate cycles, but in either case, and irrespective too of whether it is a fundamental or derived mode in the sense of Dima and Lohmann (2009), the 1500-1800-yr periodicity is widely represented in a large number of paleoclimate proxy records. It is obviously premature to reject possible links between changing solar activity at these multiple scales and the variations that are commonly observed in paleoclimatic records.

Spleen samples of 146 bats, belonging to 16 species, were tested for four DENV serotypes with standard reverse transcriptase polymerase chain reaction (RT-PCR) protocols. Six bats (4.1%) tested positive for DENV-2: four bats in Calakmul (two Glossophaga soriana, one Artibeus jamaicensis, and one A. lituratus) and two bats in Montes Azules (both A. lituratus). No effect of anthropogenic disturbance on the occurrence of DENV was detected; however, all three RT-PCR-positive bat species are considered abundant species in the Neotropics and well-adapted to disturbed habitats. To our knowledge, this study is the first study conducted in southeastern Mexico to identify DENV-2 in bats by a widely accepted RT-PCR protocol. The role that bats play on DENV's ecology remains undetermined.

The prevailing style of eruption for 60% of this time was explosive, manifested by repeated phreatic and phreatomagmatic activity in a deep summit caldera. During dominantly explosive periods, the magma supply rate to the shallow storage volume beneath the summit dropped to only a few percent of that during mainly effusive periods. The frequency and duration of explosive activity are contrary to the popular impression that Kilauea is almost unceasingly effusive. Explosive activity apparently correlates with the presence of a caldera intersecting the water table. The decrease in magma supply rate may result in caldera collapse, because erupted or intruded magma is not replaced. Glasses with unusually high MgO, TiO (sub 2) , and K (sub 2) O compositions occur only in explosive tephra (and one related lava flow) and are consistent with disruption of the shallow reservoir complex during caldera formation. Kilauea is a complex, modulated system in which melting rate, supply rate, conduit stability (in both mantle and crust), reservoir geometry, water table, and many other factors interact with one another. The hazards associated with explosive activity at Kilauea's summit would have major impact on local society if a future dominantly explosive period were to last several centuries. The association of lowered magma supply, caldera formation, and explosive activity might characterize other basaltic volcanoes, but has not been recognized.

AN - 1623272193; 2014-091434 AB - We describe a new genus and species of early Oligocene halitheriine dugongid from the Western Atlantic region. Priscosiren atlantica, gen. et sp. nov., differs from all other halitheriine dugongids by displaying the following unique combination of characters: supraorbital processes dorsoventrally thin (<1 cm) with well-developed prominent posterolateral corner; supraoccipitals wider in the dorsal half than the ventral half; exoccipitals meeting dorsal to the foramen magnum; posttympanic process with a prominent anteroventral process for attachment of m. sternomastoideus; nasals separated in midline; ventral extremity of jugal located ventral to orbit; ventral border of mandible strongly concave; absence of accessory mental foramina; dorsoventrally broad horizontal ramus of mandible; loss of all permanent premolars; and concave anteroventral surface of jugal (a possible autapomorphy). Differs further from the similar species Caribosiren turneri in having lesser rostral deflection (of about 44 degrees ); presence of small incisors; lower temporal crests; and slightly larger body size. The relationship of Priscosiren with other dugongids places it close to being a structural as well as temporal ancestor to the Metaxytherium + Hydrodamalinae and Dugonginae clades. This supports previous assumptions of a Western Atlantic and Caribbean origin for these groups, and indicates that the halitheriine-dugongine divergence must have occurred no later than the earliest Oligocene. Priscosiren, Caribosiren, and Crenatosiren evidently coexisted in the West Atlantic-Caribbean region, and constitute yet another case of a uniquely patterned fossil sirenian multispecies community.

A negative impact of solar activity (SA) was observed on the growth of these pine trees with particularly strong impact in the case of the maritime pines. The width of the annual rings was generally smaller in the years of maximum SA; furthermore, it was found that it is latewood width that is affected whereas earlywood width is not affected; as a corollary, the percentage of latewood also shows a significative negative correlation with SA.

The transparency of glacially-fed lakes may be a particularly sensitive sentinel characteristic of these changes. However, little is known about the relative contributions of glacial flour versus other factors affecting light attenuation in these lakes. We sampled 18 glacially-fed lakes in Chile, New Zealand, and the U.S. and Canadian Rocky Mountains to characterize how dissolved absorption, algal biomass (approximated by chlorophyll a), water, and glacial flour contributed to attenuation of ultraviolet radiation (UVR) and photosynthetically active radiation (PAR, 400-700nm). Variation in attenuation across lakes was related to turbidity, which we used as a proxy for the concentration of glacial flour. Turbidity-specific diffuse attenuation coefficients increased with decreasing wavelength and distance from glaciers. Regional differences in turbidity-specific diffuse attenuation coefficients were observed in short UVR wavelengths (305 and 320nm) but not at longer UVR wavelengths (380nm) or PAR. Dissolved absorption coefficients, which are closely correlated with diffuse attenuation coefficients in most non-glacially-fed lakes, represented only about one quarter of diffuse attenuation coefficients in study lakes here, whereas glacial flour contributed about two thirds across UVR and PAR. Understanding the optical characteristics of substances that regulate light attenuation in glacially-fed lakes will help elucidate the signals that these systems provide of broader environmental changes and forecast the effects of climate change on these aquatic ecosystems. Key Points * Glacial flour contributed about two thirds of lake diffuse attenuation coefficients * Turbidity-specific attenuation coefficients increased with glacier distance * Turbidity-specific attenuation coefficients were similar across regions JF - Journal of Geophysical Research.

Here, we examined how prehistoric refuse dumps ("middens") impacted soil chemistry and plant community composition in forests along the Chesapeake Bay by collecting vegetational and soil nutrient data. The centuries- to millennia-old shell middens had elevated soil nutrients compared to adjacent sites, greater vegetative cover, especially of herb and grass species, and higher species richness. Not only are middens important archaeological resources, they also offer a remarkable opportunity to test ecological hypotheses about nutrient addition over very long time scales. We found no evidence, for example, that elevated nutrients enhanced invasion by non-native species as predicted by the fluctuating resource hypothesis. However, we did find that elevated nutrients shifted community structure from woody species to herbaceous species, as predicted by the structural carbon-nutrient hypothesis. These results highlight the long-lasting effects that humans can have on abiotic and biotic properties of the natural environment, and suggest the potential for modern patterns of species' distributions and abundances to reflect ancient human activities.

Vehicle collisions are a top impact of roads on birds, with tens of millions of birds thought to be killed each year in the United States. However, currently available mortality estimates are extrapolated from a single study. We reviewed the literature and used 20 mortality rates extracted from 13 studies to systematically quantify data-driven estimates of annual U.S. mortality from bird-vehicle collisions. We generated 4 separate estimates along with uncertainty using different subsets of data deemed to be rigorous enough to contribute relatively little bias to estimates. All of our estimates of vehicle mortality are higher than previous U.S. figures. When averaging across model iterations, we estimated that between 89 and 340 million birds die annually from vehicle collisions on U.S. roads. Sensitivity analyses indicated that uncertainty about survey-related biases (scavenger removal and searcher detection of carcasses) contributes the greatest amount of uncertainty to our mortality estimates. Future studies should account for these biases to provide more accurate local estimates of mortality rates and to inform more precise national mortality estimates. We found relatively little information available to quantify regional, seasonal, and taxonomic patterns of vehicle collision risk, and substantial uncertainty remains about whether collisions contribute to large-scale impacts on bird populations. Nonetheless, the large magnitude of bird mortality caused by vehicle collisions combined with evidence that collisions can contribute to local population declines for some species highlights the need for implementation of conservation and management actions to reduce this mortality.

In Sept 1998, category 3 Hurricane Georges passed over Mona Island. This island, unlike others in the Caribbean, has had feral goats for five centuries. In this study we addressed the following questions: (i) what are the short-term (4 mo) and long-term (10 yr) responses of Mona Island's dry forests to hurricane disturbance in terms of forest structure and tree mortality; and (ii) is there any effect of goat exclusion on the recovery process and forest structure after the hurricane? Location Dry forest of Mona Island, Puerto Rico. Methods Permanent fenced and unfenced plots established in 1997 and monitored annually until 2008 were used to evaluate the interplay between goat herbivory and hurricane effects on structural dynamics of the tree community. Within these plots, vegetation data collected include species identity, DBH, successional status and hurricane-related tree mortality. Results We found that vegetation responses to hurricane disturbances may have been influenced by the presence of feral goats through at least two mechanisms. First, goats may have led to changes in forest structure and composition that feed back into the recovery dynamics that follow hurricane events. Second, goat herbivory limits the production of multiple stems, a trait that could be an adaptive response in hurricane-prone areas. Feral goats may lead to alternate successional pathways by keeping this dry forest at early-successional stages much longer than expected, and shifting vegetation communities to an alternate state where smaller, shrubbier and perhaps less palatable species dominate. Conclusions Differences in structure between Mona Island's dry forest and other tropical dry forests are related to changes in species composition that may have been triggered by introduced goats. Our results highlight the potential complexities that may arise when setting management goals within the context of novel ecosystems. Ultimately, implementation of management goals requires knowing what changes are linked to the ecological integrity of the ecosystem and what cultural values are placed on the current state of the tree community vs its historical condition. In this study we used long-term monitoring of fenced and unfenced plots to evaluate the interplay between goat herbivory and hurricane effects on tree-community structural dynamics. We found that differences in structure between Mona Island's dry forest and other tropical dry forests are related to changes in species composition that may have been triggered by introduced goats.

We analysed changes in abundance of over 4000 tree species in 12 forests across the world over periods of 6-28 years. Abundance fluctuations in all forests are large and consistent with population dynamics models in which temporal environmental variance plays a central role. At some sites we identify clear environmental drivers, such as fire and drought, that could underlie these patterns, but at other sites there is a need for further research to identify drivers. In addition, cross-site comparisons showed that abundance fluctuations were smaller at species-rich sites, consistent with the idea that stable environmental conditions promote higher diversity. Much community ecology theory emphasises demographic variance and niche stabilisation; we encourage the development of theory in which temporal environmental variance plays a central role.

Sediment from Lake Annie, an oligo-mesotrophic sinkhole with moderately acidic sediment (pH 5.4; loss on ignition 58 %), contained higher total P concentrations than sediment from eutrophic Lake Okeechobee (pH 7.7, loss on ignition 36 %) and hyper-eutrophic Lake Apopka (pH 7.5, loss on ignition 69 %). The chemical nature of sediment P varied markedly among the three lakes, suggesting the predominance of different diagenetic processes. Lake Okeechobee sediment was dominated by inorganic P, indicating the dominance of abiotic reactions; Lake Annie sediment contained abundant organic P throughout the sediment profile, indicating the importance of organic P stabilization at acidic pH; Lake Apopka contained almost half of its sediment P in microbial biomass, indicating the importance of biotic processes in regulating P dynamics. Solution super(31)P NMR spectroscopy of NaOH-EDTA extracts revealed that organic P occurred mainly as phosphomonoesters in all lakes. However, sediment from Lake Apopka also contained abundant phosphodiesters and was the only lake to contain detectable concentrations of polyphosphate, perhaps due to a combination of alternating redox conditions and high concentrations of inorganic phosphate and organic carbon. Organic P concentrations determined by sequential fractionation and solution super(31)P NMR spectroscopy were similar for all lakes when microbial P was included in values for sequential fractionation. We conclude that the chemical nature of sediment P varies markedly depending on trophic state and can provide important information on the dominant processes controlling P cycling in subtropical lakes.

AN - 1535623545; 24308994 AB - Using a calibrated bio-optical model we determined that the optical water quality conditions in several nitrogen-impaired embayments and in one unimpaired system were within the range of values known to support eelgrass growth. We also used the model to identify a range of light requirements for eelgrass (Zostera marina). Higher eelgrass light requirements, expressed as a percentage of surface-incident irradiance, corresponded with higher sediment organic matter content. These results corroborated findings by previous studies which indicate a generalized relationship: seagrasses growing in turbid conditions with poorer water and sediment quality have higher light requirements than those growing in less degraded conditions. The mechanistic reason for the variation in light requirements is still not completely explained and cannot be attributed to a single independent variable. Varying light requirement have important implications for eelgrass protection and should be considered when setting restoration targets for eelgrass in water quality and nitrogen remediation programs.

When sea level rose, this incised valley was then filled with mixed siliciclastic/carbonate sediments that record coastal environmental change over the past 10ky. Previous sedimentological and seismic analysis shows that Baffin Bay contains atypical depositional environments as a result of its semi-arid climate setting and isolation from the Gulf of Mexico. Three prominent stratigraphic surfaces can be recognized within the bay deposits, and are chronostratigraphically constrained using radiocarbon dates. The purpose of the present study is to use foraminifera to create a separate account of change and to determine if foraminiferal data corroborate sedimentological evidence for sea level and climate fluctuations. Foraminifera were sampled at 20cm intervals from a 14.4m dated core and from surface and subsurface sediments of five cores along a dip transect. Multiple discriminate analysis was used to compare sections of the core by species proportions, and clearly delineates three different foraminiferal communities: deltaic, open-bay, and hypersaline. Breaks between these communities coincide with two of the surfaces observed in the core, one at about 8.0ky and the other around 5.5ky. Rapid sea level rise at the 8.0ky flooding surface corresponds with a shift from a deltaic to an open-bay foraminiferal assemblage, while faunal change across the 5.5ky surface is due to the formation of a large barrier island (Padre Island) and the onset of more arid climate conditions. Prior to the isolation of Baffin Bay at 5.5ky, foraminiferal assemblages do not correspond to climate change records, perhaps because open circulation with the Gulf of Mexico tempered regional climate effects on bay salinity. After 5.5ky, changes in foraminiferal assemblages correspond to independently derived records of the El Nino-Southern Oscillation and North American monsoon. Foraminiferal analysis supports sedimentological interpretations in that assemblages and sediments track climate change. Abstract Copyright (2014) Elsevier, B.V.

This would suggest that such patterns are strongly determined by global abiotic factors, such as climate, or by basic eco-evolutionary processes such as filling of niches by specialization. The similarity of pattern would be expected to extend to the history of individual clades. Here, we investigate the temporal distribution of maximum size observed within individual orders globally and on separate continents. While the maximum size of individual orders of large land mammals show differences and comprise several families, the times at which orders reach their maximum size over time show strong congruence, peaking in the Middle Eocene, the Oligocene and the Plio-Pleistocene. The Eocene peak occurs when global temperature and land mammal diversity are high and is best explained as a result of niche expansion rather than abiotic forcing. Since the Eocene, there is a significant correlation between maximum size frequency and global temperature proxy. The Oligocene peak is not statistically significant and may in part be due to sampling issues. The peak in the Plio-Pleistocene occurs when global temperature and land mammal diversity are low, it is statistically the most robust one and it is best explained by global cooling. We conclude that the macroevolutionary patterns observed are a result of the interplay between eco-evolutionary processes and abiotic forcing. JF - Proceedings - Royal Society.

For each of 1,964 subbasins, we quantified the 1990 prevalence of cropland and riparian buffers. Cropland was considered buffered if the topographic flow path connecting it to a stream traversed a streamside forest or wetland. We applied a model that predicts stream nitrate concentration based on physiographic province and the watershed proportions of unbuffered and buffered cropland. We used another model to predict annual streamflow based on precipitation and temperature, and then multiplied the predicted flows and concentrations to estimate 1990 annual nitrate loads. Across the entire Chesapeake watershed, croplands released 92.3 Gg of nitrate nitrogen, but 19.8 Gg of that was removed by riparian buffers. At most, 29.4 Gg more might have been removed if buffer gaps were restored so that all cropland was buffered. The other 43.1 Gg of cropland load cannot be addressed with riparian buffers. The Coastal Plain physiographic province provided 52% of the existing buffer reduction of Bay-wide nitrate loads and 36% of potential additional removal from buffer restoration in cropland buffer gaps. Existing and restorable nitrate removal in buffers were lower in the other three major provinces because of less cropland, lower buffer prevalence, and lower average buffer nitrate removal efficiency.

By the 1950s, its geographic range had contracted to a small region along the northern frontier of Cockpit Country. The last unequivocal sight records occurred in the early 1980s, raising strong concern about the swallow's conservation status. I conducted an island-wide search for the swallow from 1994 through 2012. Standardised censuses of aerial insectivores at 1,281 sites, including the last redoubts of the Golden Swallow in Trelawny Parish, revealed no evidence of the species. These surveys and the absence of documented sight records during the past three decades suggest that the Jamaican race of the Golden Swallow is close to extinction if not already extinct. The cause of the population decline is unknown but is most likely linked to chronic predation by introduced mammalian predators, particularly the arboreal black rat Rattus rattus.

We examined changes in the forms of soil P in a 4000-yr-old subtropical peat deposit in Florida using sequential fractionation and solution (super 31) P nuclear magnetic resonance spectroscopy. By combining information on changes in soil P composition with (super 14) C dates, our aim was to estimate the long-term rate of P storage in a subtropical peatland. Diagenesis caused a decline in labile compounds and an accumulation of recalcitrant compounds. For example, stable P forms determined by sequential fractionation increased from 23% of total P in surface peat to 48 to 73% of total P at a depth of 1.5 m. In contrast, fulvic-acid bound P declined with increasing depth at a rate of 37 to 65 mu g P kg (super -1) yr (super -1) . Solution (super 31) P nuclear magnetic resonance (NMR) spectroscopy showed that the majority of the extractable organic P occurred as phosphodiesters, which declined markedly with depth, indicating recycling of labile organic P in surface sediments. Carbon-14 dating at two soil coring stations indicated a long-term P accretion rate of 1.71 mg P m (super -2) yr (super -1) at both stations, a rate approximately 20-fold lower than previous estimates of long-term P accretion in this wetland. Recently deposited material undergoes rapid biogeochemical transformations that complicate associations between soil properties and extrinsic factors such as nutrient loading. We conclude that studies of P accretion based only on approximately <200-yr-old peat will tend to overestimate long-term sequestration rate of the ecosystem.

To determine whether there are any variations in ages within separate drainage basins and subbasins that may reflect local or regional variations in climate or resetting from resurfacing (e.g., impact ejecta or lava flows), we dated 27 basins and subbasins in Sabaea and Arabia Terrae. The age-dating basin technique we employed allowed sufficient precision to give accurate ages and shows that fluvial activity within the basins and subbasins ceased at approximately the same time around the Early Hesperian/Late Hesperian transition. Our results support the hypothesis that valley networks formed during a unique "fluvial optimum" that may have shut off gradually because of a global climate change that affected all areas simultaneously on Mars.

Results have been integrated with morphologic, mineralogic, and thermophysical properties derived from orbital data, and Curiosity-based measurements, to understand the nature and origin of physical properties of traversed terrains. The hummocky plains (HP) landing site and traverse locations consist of moderately to well-consolidated bedrock of alluvial origin variably covered by slightly cohesive, hard-packed basaltic sand and dust, with both embedded and surface-strewn rock clasts. Rock clasts have been added through local bedrock weathering and impact ejecta emplacement and form a pavement-like surface in which only small clasts (<5 to 10 cm wide) have been pressed into the soil during wheel passages. The bedded fractured (BF) unit, site of Curiosity's first drilling activity, exposes several alluvial-lacustrine bedrock units with little to no soil cover and varying degrees of lithification. Small wheel sinkage values (<1 cm) for both HP and BF surfaces demonstrate that compaction resistance countering driven-wheel thrust has been minimal and that rover slippage while traversing across horizontal surfaces or going uphill, and skid going downhill, have been dominated by terrain tilts and wheel-surface material shear modulus values.

We manipulated plant species richness in old-field communities to compare the impacts of native vs. exotic species on plant biomass, seed production, and arthropod community structure. Plants within diverse communities, regardless of whether they were native or exotic, had higher biomass and seed production than in monocultures and displayed positive complementarity. Increasing native or exotic plant richness also enhanced the richness of arthropods on plants, but exotics attracted fewer arthropod species for a given arthropod abundance than did natives. Additionally, when exotic and native plants grew together, exotics suppressed seed production of native species. Thus, exotic plants appear to contribute positively to some biodiversity functions, but may impact native communities over longer time frames by reducing native seed production and recruiting fewer arthropod species.

As a focus of scientific attention, it is important to be able to assess not only the current state of Kenya's mammal communities, but also how they have changed over anthropogenic timescales. Comprehensive lists of mammal species from known areas are essential for this goal, and these also provide comparative baselines for assessing changes in mammalian diversity in the future and in the fossil record. Though there is considerable literature available for mammals inhabiting Kenyan protected areas (National Parks and Reserves), species compilation projects vary greatly in scope, completeness, agreement, and accuracy. We combine the information in these databases for Kenya and supplement them with the most up-to-date knowledge available up to November 2013. Comprehensive historical species lists were compiled from specimen lists collected during 1888-1950 in ecosystems that today correspond to 13 different protected areas. We also provide analogous modern species lists based on data collected during 1950-2012. The data sets include both large and small mammals. A master list of a total of 413 species provides ecological information including body mass, diet, feeding and shelter habitat, and activity time. Historical data are based on museum specimens and sighting records, and modern data are based on museum data as well as literature, books, field guides, written accounts, photos, and videos. We used this compilation for an analysis comparing the two data sets (excluding volant and domestic species) for six protected areas with the most complete historical records and have shown in a separate publication that species richness is preserved, but beta diversity, based on pairwise comparisons of sites in this database, is being lost over the entire study area.

The presence of linear magmatic-tectonic belts in the relatively immature central MER may indicate that the transition from mechanical to magmatic rifting is more spatially distributed and temporally protracted than has previously been assumed. Here we examine lava geochemistry and vent distribution of a Pliocene-Quaternary linear magmatic chain along the western margin of the central MER-the Akaki Magmatic Zone. Our results show limited variability in parental magma that evolve in a complex polybaric fractionation system that has not changed significantly over the past 3 Ma. Our results suggest the following: (1) channeling of plume material and the localization of shear- or topography-induced porosity modulates melt intrusion into the continental lithosphere. (2) Pre-existing lithospheric structures may act as catalysts for intrusion of magmas into the lithospheric mantle. (3) The midcrustal to upper crustal strain regime dictates the surface orientation of volcanic vents. Therefore, although linear magmatic belts like those in the central MER may young progressively toward the rift axis and superficially resemble oceanic style magmatism, they actually represent prebreakup magmatism on continental crust. The oldest linear magmatic belts observed seismically and magnetically at the edge of the ocean basins thus may not, as is often assumed, actually mark the onset of seafloor spreading.

Cosmic evolution, as a physical cosmology that notably includes life, is rich in empirical findings about many varied systems that can potentially help assess global problems facing us here on Earth. Despite its grand and ambitious objective to unify theoretical understanding of all known complex systems from big bang to humankind, cosmic evolution does have useful, practical applications from which humanity could benefit. Cosmic evolution's emphasis on quantitative data analyses might well inform our attitudes toward several serious issues now challenging 21 super(st)-century society, including global warming, smart machines, world economics, and cancer research. This paper comprises one physicist's conjectures about each of these applied topics, suggesting how energy-flow modeling can guide our search for viable solutions to real-world predicaments confronting civilization today.

The Fe/Si data display a clear dependence on phase angle, for which the results are empirically corrected. Mercury's surface has a low total abundance of Fe, with a mean Fe/Si ratio of approximately 0.06 (equivalent to approximately 1.5 wt% Fe). The absolute Fe/Si values are subject to a number of systematic uncertainties, including the phase-angle correction and possible mineral mixing effects. Individual Fe/Si measurements have an intrinsic error of approximately 10%. Observed Fe/Si values display small variations (significant at two standard deviations) from the planetary average value across large regions in Mercury's southern hemisphere. Larger differences are observed between measured Fe/Si values from more spatially resolved footprints on volcanic smooth plains deposits in the northern hemisphere and from those in surrounding terrains. Fe is most likely contained as a minor component in sulfide phases (e.g., troilite, niningerite, daubreelite) and as Fe metal, rather than within mafic silicates. Variations in surface reflectance (i.e., differences in overall reflectance and spectral slope) across Mercury are unlikely to be caused by variations in the abundance of Fe.

Data recorded at each capture included the date, 24-hour military time, body temperature (BT), air temperature (AT), ground-surface temperature (ST), water temperature (WT) if in water, and the snake's activity (under cover, moving on land, basking, foraging, climbing, swimming, courting/mating). The purpose of this study was to determine the potential range of operating body temperature (OBT) of the individual species. The range of OBT is interpreted as the snake's operating temperature at its current environmental temperatures (ET), which can be used in comparisons with similar data from other North American regions, and represents the first such report from the Mid-Atlantic Region. The mean and ranges of BT, AT, ST, and WT are presented for the eight snakes with 20 or more records: Carphophis amoenus (n = 238), Coluber constrictor (204), Nerodia sipedon (67), Thamnophis sirtalis (55), Diadophis punctatus (54), Pantherophis alleghaniensis (43), Thamnophis sauritus (26), and Agkistrodon contortrix (24). New thermal records are reported for several of these species. The ranges of BT during activities are also reported. New temperature records are also reported for Virginia valeriae (n = 16 encounters), Storeria dekayi (12), Opheodrys aestivus (6), Lampropeltis calligaster (6), and Regina septemvittata (2).

Previous studies have used simple di- to triterpenoid ratios to reconstruct floral changes in the geologic past, but few have compared terpenoid ratios with estimates of floral composition from fossils. Further, reconstructions have not taken into account differences in biomarker production (i.e. concentration relative to leaf biomass) between different types of plants. Here, we have examined terpenoids from early Cenozoic fluvial rocks from the Bighorn Basin (Wyoming, USA), where fossil flora has been studied in detail. We analyzed the distributions of diterpenoids, triterpenoids and n-alkanes from leaf wax in a total of 43 samples from 15 stratigraphic horizons of late Paleocene (63 Ma) to early Eocene (53 Ma) in age. In nearly all samples, triterpenoids, derived from angiosperms, were significantly lower in abundance than conifer-specific diterpenoids, a finding that contrasted with plant fossil evidence for the same rocks. This suggests that di- to triterpenoid ratios severely underestimate the abundance of angiosperms in paleovegetation. Angiosperms dominated n-alkane production among modern plants, and we propose a new paleovegetation proxy based on the ratio of diterpenoids (conifers) to n-alkanes (angiosperms), corrected for lipid production estimated from extant vegetation. Using diterpenoids and alkanes, we infer the composition of paleovegetation to be similar to that inferred from plant fossils. Although the approach works well for the Bighorn Basin, we stress the new paleovegetation proxy will need to be evaluated for other time periods, communities, paleogeography and depositional environments with pollen or megafossil data available.

Repeat censuses of tree plots are key tools for investigating forest carbon fluxes. Current measurement procedures for trees with buttresses or trunk irregularities - trees that account for a large fraction of tropical forest biomass -introduce substantial systematic error in plot-level estimates of biomass change. The diameters of buttressed trees are measured above the standard height of 1.3 m, and the measurement heights on individual trees are often moved upwards as buttresses grow. Because tree trunks taper (diameter decreases with height), biomass growth in buttressed individuals tends to be underestimated. Methods have been introduced to correct biomass growth estimates in individual trees for increases in measurement height; however, these methods change the distribution of effective measurement heights over time, introducing biases in plot-level estimates of biomass change. 2. In this study, we developed and applied new methods to measure and model trunk taper, and to use taper models to correct estimates of AGB change for changing measurement heights. We measured trunk taper above buttresses in 190 stems on Barro Colorado Island, Panama (BCI), a site where more than half of forest biomass is in trees measured above standard height. We compared proposed taper models to see which best described our measured taper data, then used the best taper model to correct for changing measurement heights in the historical plot data. Specifically, for all diameter measurements taken above 1.3 m, we calculated equivalent diameters at 1.3 m and substituted these into allometric equations to examine biomass change over time. 3. We found that measured taper was best fit by an exponential model with a rate parameter that varied with measured diameter (tree size), height of measurement (buttress height) and species. Whereas uncorrected data show a decrease in biomass of 0.21% year super(-1) between 1985 and 2010 on BCI, taper-corrected data show an increase of 0.18% year super(-1). 4. The novel correction method presented here converts all measured diameters to one standard effective measurement height. This corrects for biases at the plot level and provides a stronger foundation for measuring biomass change in tropical forests.

Studies have shown that in the interest of reducing energy expenditure, animals selectively navigate the landscape using a variety of strategies. However, these studies have generally focused on terrestrial animals. Here we present data on an exceedingly mobile arboreal animal, bearded saki monkeys, in a topographically variable landscape in Suriname. Using ArcMap and Google Earth, we explore two potential navigation strategies: the nonrandom use of travel areas and the use of ridges in slope navigation. Over a year of data collection, bearded sakis were found to use relatively long travel paths daily, use some areas more intensely than others for travel, and when travel paths were converted to strings of points, 40.3% and 63.9% of the points were located on (50m from the main ridgeline) or near (100m from the main ridgeline) ridge tops, respectively. Thus in a habitat of high relief we found support for intensive use of ridge tops or slopes close to ridge tops by bearded sakis. Selective habitat use may be related to surveying tree crowns for fruit by large, fast moving groups of bearded sakis or monitoring the presence of potential predators. Am. J.

Despite the popularity of this method, validation studies evaluating its accuracy across a variety of samples are lacking. Furthermore, it remains unclear what other intrinsic or extrinsic variables are related to the expression of these traits. In this study, cranial trait scores and postcranial measurements were collected from four diverse population groups (U.S. Whites, U.S. Blacks, medieval Nubians, and Arikara Native Americans) following Walker's protocols (total n=  ;499). Univariate and multivariate analyses were utilized to evaluate the accuracy of these traits in sex estimation, and to test for the effects of population, age, and body size on trait expressions. Results revealed significant effects of population on all trait scores. Sample-specific correct sex classification rates ranged from 74% to 94%, with an overall accuracy of 85% for the pooled sample. Classification performance varied among the traits (best for glabella and mastoid scores and worst for nuchal scores). Furthermore, correlations between traits were weak or nonsignificant, suggesting that different factors may influence individual traits. Some traits displayed correlations with age and/or postcranial size that were significant but weak, and within-population analyses did not reveal any consistent relationships between these traits across all groups. These results indicate that neither age nor body size plays a large role in trait expression, and thus does not need to be incorporated into sex estimation methods.

In Caribbean coral reefs, several species of snapping shrimp (Synalpheus spp.) dwell exclusively in marine sponges, which serve as both habitat and food source. A paired experimental design was used to examine the effects of Synalpheus occupancy on predation, morphology, and growth of their sponge host Lissodendoryx colombiensis in Bocas del Toro, Panama (9.351 degree N, 82.258 degree W) in June 2009. Shrimp occupancy significantly decreased consumption of sponges by a predatory sea star (Oreaster reticulatus) and also affected sponge morphology; sponges grown without shrimps decreased in canal size, in both the laboratory and the field. Shrimp occupancy had more ambiguous effects on sponge growth. In laboratory experiments, shrimp occupancy benefited sponge growth, although all sponges experienced overall decreases in mass. In field experiments, there were no significant differences in growth between occupied and empty sponges. However, the benefits of shrimp occupancy on sponge growth were negatively correlated with overall increases in sponge size; sponges that decreased in mass during the experiment benefited more from shrimp occupancy than sponges that increased in mass. These costs and benefits suggest that Synalpheus has variable effects on sponges: positive effects on sponges in the presence of predators, and/or when sponges are decreasing in mass (e.g., during periods of physical stress), but a negative effect on sponges during periods of active sponge growth.

Our knowledge of malaria vectorial importance and the distribution and evolution of these taxa is incomplete. We constructed ecological niche models (ENMs) for these taxa and used hypothesized phylogenetic relationships and ENMs to investigate environmental and ecological divergence associated with speciation events. Two major clades were identified, one north (Clade 1) and one south (Clade 2) of the Amazon River that likely is or was a barrier to mosquito movement. Clade 1 species occur more often in higher average temperature locations than Clade 2 species, and taxon splits within Clade 1 corresponded with a greater divergence of variables related to precipitation than was the case within Clade 2. Comparison of the ecological profiles of sympatric species and sister species support the idea that phylogenetic proximity is related to ecological similarity. Anopheles albitarsis I, An. janconnae, and An. marajoara ENMs had the highest percentage of their predicted suitable habitat overlapping distribution models of Plasmodium falciparum and P. vivax, and warrant additional studies of the transmission potential of these species. Phylogenetic proximity may be related to malaria vectorial importance within the Albitarsis Group.

To address this, we examined the delta super(15)N values of soluble soil N and canopy foliage of four tree species after 13 years of factorial N and P addition to a mature lowland rainforest. We hypothesized that N addition would lead to super(15)N-enriched soil N forms due to fractionating losses, whereas P addition would reduce N losses as the plants and microbes adjusted their stoichiometric demands. Chronic N addition increased the concentration and delta super(15)N value of soil nitrate and delta super(15)N in live and senesced leaves in two of four tree species, but did not affect ammonium or dissolved organic N. Phosphorus addition significantly increased foliar delta super(15)N in one tree species and elicited significant N P interactions in two others due to a reduction in foliar delta super(15)N enrichment under N and P co-addition. Isotope mixing models indicated that three of four tree species increased their use of nitrate relative to ammonium following N addition, supporting the expectation that tropical trees use the most available form of mineral N. Previous observations that anthropogenic N deposition in this tropical region have led to increasing foliar delta super(15)N values over decadal time-scales is now mechanistically linked to greater usage of super(15)N-enriched nitrate.

We did not detect 2009 BD in 25 hr of integration at 4.5 mu m. Based on an upper-limit flux density determination from our data, we present a probabilistic derivation of the physical properties of this object. The analysis is based on the combination of a thermophysical model with an orbital model accounting for the non-gravitational forces acting upon the body. We find two physically possible solutions. The first solution shows 2009 BD as a 2.9 + or - 0.3 m diameter rocky body (rho = 2.9 + or - 0.5 g cm (super -3) ) with an extremely high albedo of (sub IMG .../ (super that is covered with regolith-like material, causing it to exhibit a low thermal inertia ( (sub IMG .../ (super SI units). The second solution suggests 2009 BD to be a 4 + or - 1 m diameter asteroid with (sub IMG .../ (super that consists of a collection of individual bare rock slabs (Gamma = 2000 + or - 1000 SI units, (sub IMG .../ (super g cm (super -3) ). We are unable to rule out either solution based on physical reasoning. 2009 BD is the smallest asteroid for which physical properties have been constrained, in this case using an indirect method and based on a detection limit, providing unique information on the physical properties of objects in the size range smaller than 10 m.

The minimum (or critical) core mass to form a gas giant is typically quoted as 10 M (sub ⊕) . The actual value depends on several factors: the location in the protoplanetary disk, atmospheric opacity, and the accretion rate of solids. Motivated by ongoing direct imaging searches for giant planets, this study investigates core mass requirements in the outer disk. To determine the fastest allowed rates of gas accretion, we consider solid cores that no longer accrete planetesimals, as this would heat the gaseous envelope. Our spherical, two-layer atmospheric cooling model includes an inner convective region and an outer radiative zone that matches onto the disk. We determine the minimum core mass for a giant planet to form within a typical disk lifetime of 3 Myr. The minimum core mass declines with disk radius, from approximately 8.5 M (sub ⊕) at 5 AU to approximately 3.5 M (sub ⊕) at 100 AU, with standard interstellar grain opacities. Lower temperatures in the outer disk explain this trend, while variations in disk density are less influential. At all distances, a lower dust opacity or higher mean molecular weight reduces the critical core mass. Our non-self-gravitating, analytic cooling model reveals that self-gravity significantly affects early atmospheric evolution, starting when the atmosphere is only approximately 10% as massive as the core.

Our analysis is based on a novel approach to the power-law size distribution of solid particles central to each model. When impacts produce debris with (1) little material in the largest remnant and (2) a steep size distribution, the debris has enough cross-sectional area to match observations of Fomalhaut b. However, published numerical experiments of impacts between 100 km objects suggest this outcome is unlikely. If collisional processes maintain a steep size distribution over a broad range of particle sizes (300 mu m to 10 km), Earth-mass planets can capture enough material over 1-100 Myr to produce a detectable cloud of dust. Otherwise, capture fails. When young planets are surrounded by massive clouds or disks of satellites, a collisional cascade is the simplest mechanism for dust production in Fomalhaut b. Several tests using Hubble Space Telescope or James Webb Space Telescope data-including measuring the expansion/elongation of Fomalhaut b, looking for trails of small particles along Fomalhaut b's orbit, and obtaining low resolution spectroscopy-can discriminate among these models.

Despite the widespread use of this approach to understand ecosystem metabolism, we are only beginning to understand the degree and underlying causes of uncertainty for metabolism model parameter estimates. Here, we present a novel approach to improve the precision and accuracy of ecosystem metabolism estimates by identifying physical metrics that indicate when metabolism estimates are highly uncertain. Using datasets from seventeen instrumented GLEON (Global Lake Ecological Observatory Network) lakes, we discovered that many physical characteristics correlated with uncertainty, including PAR (photosynthetically active radiation, 400-700 nm), daily variance in Schmidt stability, and wind speed. Low PAR was a consistent predictor of high variance in GPP model parameters, but also corresponded with low ER model parameter variance. We identified a threshold (30% of clear sky PAR) below which GPP parameter variance increased rapidly and was significantly greater in nearly all lakes compared with variance on days with PAR levels above this threshold. The relationship between daily variance in Schmidt stability and GPP model parameter variance depended on trophic status, whereas daily variance in Schmidt stability was consistently positively related to ER model parameter variance. Wind speeds in the range of ~0.8-3 m s super(-1) were consistent predictors of high variance for both GPP and ER model parameters, with greater uncertainty in eutrophic lakes. Our findings can be used to reduce ecosystem metabolism model parameter uncertainty and identify potential sources of that uncertainty.

Unfortunately, for most species, we are lacking such information. The North American Bird Banding Laboratory (BBL) houses an extensive database of marking, recaptures and recoveries, and such data could provide migratory connectivity information for many species. To date, however, few species have been analyzed for migratory connectivity largely because heterogeneous re-encounter probabilities make interpretation problematic. We accounted for regional variation in re-encounter probabilities by borrowing information across species and by using effort covariates on recapture and recovery probabilities in a multistate capture-recapture and recovery model. The effort covariates were derived from recaptures and recoveries of species within the same regions. We estimated the migratory connectivity for three tern species breeding in North America and over-wintering in the tropics, common (Sterna hirundo), roseate (Sterna dougallii), and Caspian terns (Hydroprogne caspia). For western breeding terns, model-derived estimates of migratory connectivity differed considerably from those derived directly from the proportions of re-encounters. Conversely, for eastern breeding terns, estimates were merely refined by the inclusion of re-encounter probabilities. In general, eastern breeding terns were strongly connected to eastern South America, and western breeding terns were strongly linked to the more western parts of the nonbreeding range under both models. Through simulation, we found this approach is likely useful for many species in the BBL database, although precision improved with higher re-encounter probabilities and stronger migratory connectivity. We describe an approach to deal with the inherent biases in BBL banding and re-encounter data to demonstrate that this large dataset is a valuable source of information about the migratory connectivity of the birds of North America. Understanding the biology and conducting effective conservation of migratory species requires knowledge of migratory connectivity, the geographic linkages of populations between stages of the annual cycle. Unfortunately, we are lacking this information for most migratory species. We demonstrate the use of available large-scale banding and re-encounter data to estimate migratory connectivity for North American breeding birds in a multistate recapture and recovery model that accounts for re-encounter probabilities.

The species most tolerant of high elevation and low salinity in New Zealand, Trochamminita salsa, was strongly dominant in most cores but two other species, Haplophragmoides wilberti and Trochammina inflata, occurred in sufficient numbers in several cores to allow analysis. We found that the highest salt marsh foraminifera live at variable depths, sometimes in low numbers down to 30 cm at least. T. salsa appears to occur at greater depths (maximum densities between 5 and 13 cm) than H. wilberti and T. inflata (maximum densities in upper 5 cm). No strong evidence was observed for significant seasonal blooms of these agglutinated species in these highest marsh cores that are only inundated by the tide for a matter of hours a few times per year. Using the size of the total live stock in each core, the downcore density profile of dead tests and the relatively constant sediment accumulation rates we calculated estimates for the mean life spans of these high marsh foraminiferal species by two slightly different methods. Before accepting these life span estimates we compared the actual depth profiles of dead test density in each core with modelled downcore test density profiles based on ideal conditions of constant sedimentation rates, constant livestock numbers, constant live depth distributions and no taphonomic loss. Estimates from three of our cores are rejected because their dead test profiles suggest significant taphonomic loss in the intervals of interest. Estimates from the remaining eight cores indicate that the highest salt marsh foraminifera in temperate New Zealand have mean life spans of 1.3-13 years, with means of 5.5 years for T. salsa, 4.5 years for T. inflata and 3 years for H. wilberti - showing progressively shorter life spans at lower elevations in less stressful environments. These life span estimates are considerably longer than the majority reported for foraminifera from less harsh conditions but help explain how highest marsh foraminifera survive and grow in this extreme environment.

Yet such regimes have origins in a much more specific context: the structures and practices of wine-making in the elite wine regions of France. This article examines the relationships between different types of communities and structures involved in boundary-making under the prototypical GI system, appellation d'origine contrôlée (AOC), in its place of origin, Bordeaux. Here, legal boundaries are simultaneously reinforced, created, and defined by the values and priorities of the society that created them. In this article I consider geographical indications in Bordeaux not only as communal rights but as communal emanations, both to highlight the idiosyncrasies of AOC as a legal system and some of the problems and possibilities status suggests for the future of intellectual property rights.

Although camera trapping has been shown to be a highly effective non-invasive tool for wildlife monitoring, the technique has not yet been widely applied to studies of arboreal species. Despite the unique challenges that camera trapping in the canopy poses, its versatility and relatively non-invasive nature, combined with recent technological improvements on the cameras themselves, make camera trapping a highly useful tool for arboreal research. 2. We present data on the methodology and effectiveness of arboreal camera trapping during the first 6 months of a year-long study in the Lower Urubamba Region of Peru investigating animal use of natural crossing points (i.e. branches) over a natural gas pipeline clearing. We placed Reconyx PC800 Hyperfire cameras in 25 crossing points of 13 distinct natural canopy 'bridges' at a mean height of 26.8 m. 3. After 6 months of data collection, we logged 1522 photoevents, recording 20 mammal, 23 bird and four reptile species. An analysis of animal passing events in front of the cameras over time did not suggest any negative response to camera presence. While we found that cameras in the canopy are triggered more frequently by non-target stimuli (e.g. leaves) than cameras on the ground, we demonstrated significantly reduced false triggering following leaf removal within 1.5 m of the camera. 4. Our results suggest that arboreal camera trapping can provide robust documentation of a diversity of vertebrate species engaged in a variety of activities, and we provide recommendations for other researchers interested in using in this method. This is the most extensive arboreal camera trapping study to date in terms of the length of the study period, the number of cameras being used and the height of the cameras in the trees. Therefore, lessons provided from this experience can be used to improve the design of future arboreal camera trap studies.

By viewing animal movement paths as realizations of a continuous stochastic process, we introduce a rigorous likelihood method for estimating the statistical parameters of movement processes. This method makes no assumption of a hidden Markov property, places no special emphasis on the sampling rate, is insensitive to irregular sampling and data gaps, can produce reasonable estimates with limited sample sizes and can be used to assign AIC values to a vast array of qualitatively different models of animal movement at the individual and population levels. 2. To develop our approach, we consider the likelihood of the first two cumulants of stochastic processes, the mean and autocorrelation functions. Together, these measures provide a considerable degree of information regarding searching, foraging, migration and other aspects of animal movement. As a specific example, we develop the likelihood analyses necessary to contrast performance of animal movement models based on Brownian motion, the Ornstein-Uhlenbeck process and a generalization of the Ornstein-Uhlenbeck process that includes ballistic bouts. 3. We then show how our framework also provides a new and more accurate approach to home-range estimation when compared to estimators that neglect autocorrelation in the movement path. 4. We apply our methods to a data set on Mongolian gazelles (Procapra gutturosa) to identify the movement behaviours and their associated time and length scales that characterize the movement of each individual. Additionally, we show that gazelle annual ranges are vastly larger than those of other non-migratory ungulates.

To test this theory, we experimentally examined intra- and interspecific interactions between a globally invasive fish, round goby (Neogobius melanostomus), and three native species at different round goby densities in a tributary of the Laurentian Great Lakes. Eighteen 2.25 m super(2) enclosures were stocked with native fish species at natural abundances, while round gobies were stocked at three different densities: 0 m super(-2), 2.7 m super(-2), and 10.7 m super(-2). After 52 days, native fish growth rate was significantly reduced in the low density goby treatment, while growth in the high density goby treatment mirrored the goby-free treatment for two of three native species. Invertebrate density and gut content weight of native fishes did not differ among treatments. Conversely, gut content weight and growth of round gobies were lower in the high goby density treatment, suggesting interactions between round gobies and native fishes are mediated by interference competition amongst gobies. Our experiment provides evidence that invasive species effects may diminish at high densities, possibly due to increased intraspecific interactions. This is consistent with some ecological theory, and cautions against the assumption that invasive species at moderate densities have low impact.

In coastal ecosystems, the relative effects of aspects of global climate change (e.g. CO2 concentrations) and localized stressors (e.g. eutrophication), in combination, have received limited attention.Using a long-term (11 month) field experiment, we examine how epiphyte assemblages in a tropical seagrass meadow respond to factorial manipulations of dissolved carbon dioxide (CO2(aq)) and nutrient enrichment. In situ CO2(aq) manipulations were conducted using clear, open-top chambers, which replicated carbonate parameter forecasts for the year 2100. Nutrient enrichment consisted of monthly additions of slow-release fertilizer, nitrogen (N) and phosphorus (P), to the sediments at rates equivalent to theoretical maximum rates of anthropogenic loading within the region (1.54 g N m-2 d-1 and 0.24 g P m-2 d-1).Epiphyte community structure was assessed on a seasonal basis and revealed declines in the abundance of coralline algae, along with increases in filamentous algae under elevated CO2(aq). Surprisingly, nutrient enrichment had no effect on epiphyte community structure or overall epiphyte loading. Interactions between CO2(aq) and nutrient enrichment were not detected. Furthermore, CO2(aq)-mediated responses in the epiphyte community displayed strong seasonality, suggesting that climate change studies in variable environments should be conducted over extended time-scales.Synthesis. The observed responses indicate that for certain locations, global stressors such as ocean acidification may take precedence over local eutrophication in altering the community structure of seagrass epiphyte assemblages. Given that nutrient-driven algal overgrowth is commonly cited as a widespread cause of seagrass decline, our findings highlight that alternate climate change forces may exert proximate control over epiphyte community structure.

AN - 1521325433; 24175996 AB - The picoplanktonic cyanobacteria, Synechococcus spp., (Nägeli) are important contributors to global ocean primary production that can be stressed by solar radiation, both in the photosynthetically active (PAR) and ultraviolet (UV) range. We studied the responses of PSII quantum yield (active fluorescence), carbon fixation ((14)C assimilation) and oxygen evolution (membrane inlet mass spectrometry) in Synechococcus WH8102 under moderate UV and PAR. PSII quantum yield decreased during exposure to moderate UV and UV+PAR, with response to the latter being faster (6.4 versus 2.8 min, respectively). Repair processes were also faster when UV+PAR exposure was followed by moderate PAR (1.68 min response time) than when UV was followed by very low PAR (10.5 min response time). For the UV+PAR treatment, the initial decrease in quantum yield was followed by a 50% increase ("rebound") after 7 min exposure, showing an apparent photoprotection induction. While oxygen uptake increased with PAR, it did not change under UV, suggesting that this oxygen-dependent mechanism of photoprotection, which may be acting as an electron sink, is not an important strategy against UV. We used propyl gallate, an antioxidant, to test for plastid terminal oxidase (ptox) or ptox-like enzymes activity, but it caused nonspecific and toxic effects on Synechococcus WH8102. © 2013 The American Society of Photobiology.

To investigate this, we evaluated the reproductive phenology and the nutrient and physiological traits in those two species and their F sub(1) hybrids genotyped with microsatellite data across a natural hybrid zone from the Pacific coast of Panama. We found no evidence that reproductive phenology represents a barrier to gene flow, because R. mangle and the F sub(1) hybrids produced flowers and propagules throughout the annual cycle, while R. racemosa flowered only in the dry season. Soil nutrient concentrations decreased landward, while soil salinity varied only slightly. Foliar nutrients and delta super(15)N signatures varied according to the soil nutrient gradient, but only foliar phosphorus and carbon varied among species. In contrast, two structural variables (height and trunk diameter) and leaf variables related to salinity tolerance (Na, Cl:Na, K:Na, cation:anion) and water-use efficiency (i.e., delta super(13)C) differed among species, suggesting higher salinity tolerance for R. mangle and F sub(1) hybrids compared with R. racemosa. We conclude that parental species and F sub(1) hybrids differ in salinity tolerance and water-use efficiency, which could be associated with adaptive evolution of the red mangrove hybrid complex.

Experiments have shown that there is a positive relationship between biodiversity and ecosystem functioning, but intense debate exists on the underlying mechanisms. While some argue that mechanisms such as niche complementarity increase ecosystem function, others argue that these relationships are a selection effect. Location Eleven tropical forests in the Americas, Africa and Asia. Methods We analysed the correlates of biodiversity and carbon storage in tropical forests using data from 59 1-ha tree plots from a standardized global tropical forest biodiversity-monitoring network. We examined taxonomic and functional diversity, aboveground C storage and environmental variables in order to determine the relationships between biodiversity and carbon storage in natural (non-plantation) tropical forests. Results We found that aboveground C storage in tropical forests increased with both taxonomic diversity and functional dominance, specifically the dominance of genera with large maximum diameters, after potential environmental drivers were accounted for (final model R super(2)=0.38, P<0.001). Main conclusions Our results suggest that niche complementarity and the selection effect are not mutually exclusive: they both play a role in structuring tropical forests. While previous studies have documented relationships between diversity and C storage, these have largely been conducted on small scales in biomes that are relatively species poor compared with tropical forests (e.g. grasslands and temperate or boreal forests). Our results demonstrate that these positive biodiversity-ecosystem functioning relationships are also present in hyperdiverse systems on spatial scales relevant to conservation and management. This insight can be used to inform the conservation and management of tropical forests, which play a critical role in the global carbon cycle and are some of the biologically richest ecosystems on the planet.

Beyond human causes, mass strandings have been attributed to herding behaviour, large-scale oceanographic fronts and harmful algal blooms (HABs). Because algal toxins cause organ failure in marine mammals, HABs are the most common mass stranding agent with broad geographical and widespread taxonomic impact. Toxin-mediated mortalities in marine food webs have the potential to occur over geological timescales, but direct evidence for their antiquity has been lacking. Here, we describe an unusually dense accumulation of fossil marine vertebrates from Cerro Ballena, a Late Miocene locality in Atacama Region of Chile, preserving over 40 skeletons of rorqual whales, sperm whales, seals, aquatic sloths, walrus-whales and predatory bony fish. Marine mammal skeletons are distributed in four discrete horizons at the site, representing a recurring accumulation mechanism. Taphonomic analysis points to strong spatial focusing with a rapid death mechanism at sea, before being buried on a barrier-protected supratidal flat. In modern settings, HABs are the only known natural cause for such repeated, multispecies accumulations. This proposed agent suggests that upwelling zones elsewhere in the world should preserve fossil marine vertebrate accumulations in similar modes and densities. JF - Proceedings - Royal Society.

The first robber fly from Burmese amber, [dagger]Burmapogon bruckschi, new genus and species, is described based on specimens of both sexes. A scientific name is provided for the previously described but unnamed fossil assassin fly from Raritan amber, [dagger]Cretagaster raritanensis, new genus and species, preserved as a fragmentary specimen. The amber fossils are placed phylogenetically within Asilidae. Specifically, [dagger]Burmapogon is postulated to be a representative of the clade comprised of (Brachyrhopalinae + Stichopogoninae), while [dagger]Cretagaster is a member of the Leptogastrinae and postulated to be an extinct sister group to (Acronychini + Leptogastrini).

We examine the variability properties of three GRMHD simulations of thin accretion disks around black holes of varying spin, producing light curves and power spectra as would be seen by observers. We find that the simulated power spectra show a broad feature at high frequency, which increases in amplitude with the inclination of the observer. We show that this high-frequency feature is a product of the Doppler effect and that its location is a function of the mass and spin of the black hole. This Doppler feature demonstrates that power spectral properties of the accretion disk can be tied to, and potentially used to determine, physical properties of the black hole.

Numerical simulations of postemission processing and dispersal of Tungurahua's SO (sub 2) emissions enable more effective comparison of ground- and satellite-based SO (sub 2) data sets, reducing the difference between them and constraining the impact of plume processing on satellite SO (sub 2) observations. Ground-based measurements of SO (sub 2) emission rate are used as the model input, and simulated SO (sub 2) mass loadings are compared to those measured by the Ozone Monitoring Instrument (OMI). The changing extent of SO (sub 2) processing has a significant impact on daily variation in SO (sub 2) mass loading for a fixed volcanic emission rate. However, variations in emission rate at Tungurahua are large, suggesting that overall volcanic source strength and not subsequent processing is more likely to be the dominant control on atmospheric mass loading. SO (sub 2) emission rate estimates are derived directly from the OMI observations using modeled SO (sub 2) lifetime. Good agreement is achieved between both observed and simulated mass loadings ( approximately 21%) and satellite-derived and ground-measured SO (sub 2) emission rates ( approximately 18%), with a factor of 2 improvement over the differences found by simple direct comparison. While the balance of emission source strength and postemission processing will differ between volcanoes and regions, under good observation conditions and where SO (sub 2) lifetime is approximately 24 hours, satellite-based sensors like OMI may provide daily observations of SO (sub 2) mass loading which are a good proxy for volcanic source strength.

The ecological dominance of marine mammals can be traced back to at least seven independent transitions during the Cenozoic, when different lineages of terrestrial mammals underwent land to sea evolutionary transformations. However, the evolution of marine mammals represents only the most recent set of marine invasions by tetrapods over the past 250 Ma. During the Mesozoic, over a dozen different reptile lineages (e.g., mosasaurs, ichthyosaurs, turtles, snakes) evolved obligate marine lineages, including a few lineages that persist to today, such as sea turtles. Birds, which are phylogenetically nested among diapsid reptiles, have also repeatedly adapted to marine life since the Cretaceous. Attempts to understand the common patterns of marine tetrapod evolution, and the processes that have shaped them, have largely been limited to individual groups. Placed in a broad comparative view from the Mesozoic to the Cenozoic eras, the macroevolution of marine tetrapods reveals evolutionary drivers at different scales, along with morphological parallels, unique evolutionary innovations, and the strong influence of historical constraints. Major physical, environmental drivers appear to be responsible for some patterns in marine tetrapod evolution at some temporal and geographic scales, but these drivers are not unique causes, as biological drivers (e.g., escalation) likely also play a role. The culmination of this trophic ascendancy has been dramatically altered by human hunting (especially of marine mammals), underscoring the need for historical datasets that extend into deep time to understand the ecological history of marine tetrapods.

Large predators may be particularly sensitive to changes in habitat availability and marine productivity driven by changes in sea-level, especially those dependent on nearshore benthic food resources. To test this relationship, we compared the proportional diversity of differing marine reptile ecotypes through the Triassic with the isotopic composition of seawater strontium ( (super 87) Sr/ (super 86) Sr), a geochemical index linked to tectonically controlled sea-level change. The proportional abundance of marine reptiles adapted toward a diet of shelled prey rose during times of rapid sea-level rise and fell during times of rapid sea-level fall, while open water forms were more resistant to these changes. Our results indicate that the rate of sea-level change, rather than the absolute magnitude of sea-level or flooded shelf area, played a role in shaping patterns of ecological diversification and ecologically selective extinction during the Triassic. The link between the isotopic composition of seawater strontium and the evolution of marine reptiles demonstrates that sea-level change played an important role in the structuring of marine ecosystems over geologic time.

These environmental changes impacted marine productivity and may have sparked the evolution of the distinct bulk-feeding strategy used by mysticete whales today. The movements and feeding habits of living cetaceans can be tracked using the isotopic composition of the structural carbonate within bioapatite of their bones and teeth, which records latitudinal gradients in marine delta (super 13) C and delta (super 18) O values. Here, we exploit this relationship to determine the past movements and feeding habits of late-surviving archaeocetes (kekenodontids) and early odontocetes and mysticetes sampled from Oligocene fossil sites in the USA (latitude: approximately 30 degrees N) and New Zealand (latitude: approximately 50 degrees S). Bioapatite delta (super 13) C and delta (super 18) O values for fossilized tooth enamel and bullae from fossil cetaceans were surprisingly similar to those for living cetaceans, which indicates that the feeding habits of these species and the isotopic composition of Oligocene seawater (ca. 28 Ma) were very close to present-day conditions. Values for toothed mysticetes and odontocetes match expectations based on cetacean species feeding at these latitudes today, suggesting these individuals were residents that foraged in close proximity to where their fossils were discovered. In contrast, the extremely low delta (super 13) C and delta (super 18) O values for some edentulous mysticetes from New Zealand are more similar to values observed in extant mysticetes that seasonally migrate to high latitudes, where they bulk-feed on lipid-rich zooplankton. Enamel delta (super 13) C values for kekenodontids showed the greatest range and overlapped with both edentulous mysticetes and resident species; these differences correlate most strongly with tooth type and may reflect an ontogenetic shift in diet associated with the transition from nursing to marine prey. When combined with evidence of increasing morphological disparity, fossil bioapatite delta (super 13) C and delta (super 18) O values support interpretations that the Oligocene was an interval of heightened taxonomic and ecological diversification within Cetacea.

Their fossil record extends back to the Mesozoic, but it is relatively poor and fragmentary, with large temporal and geographical gaps. As a result, very little is known about the paleobiogeography of these plants and how physical drivers, such as climatic or oceanic events, have affected their distribution. One approach is to infer the past distribution of seagrasses using fossils of organisms dependent of seagrasses with more complete records as proxies. Seagrass consumers, such as sirenians (seacows, manatees and dugongs), are much better represented in the fossil record than seagrasses are. The characteristically dense bones of sirenians together with the fact that they are usually found in marginal marine environments increases the potential for preservation and recognition of their fossils. The long evolutionary history of sirenians, extending throughout most of the last 50 Ma, together with their diet permits the use of their fossils as a proxy for inferring the paleobiogeography of seagrasses. Here I looked at the fossil record of sirenians and seagrasses from the Eocene, through the Miocene epochs. This comparison produced several inferences about seagrass paleobiogeography and how physical drivers, such as climate change, ocean currents and tectonic events, have been influential in their distribution: 1) seagrasses were well-established in the Western Atlantic-Caribbean prior to the middle Eocene, making possible at least two instances of trans-Atlantic sirenian dispersal events, either with the aid of Tethyan currents or along the nearly continuous Northern Atlantic coastline that was present in the Eocene; 2) climatic cooling during the early Oligocene seemed to have limited the extent of seagrasses and sirenians, although these groups recovered and further diversified and expanded their distributions by the late Oligocene in tandem with a climatic warming event; 3) by the Miocene, seagrasses and sirenians reached the southern Western Atlantic and the Eastern Pacific aided by the presence of the Central American Seaway, achieving a distribution similar to, and sometimes, surpassing that of today. The fossil record of sirenians can provide a broad overview of seagrass paleobiogeography through time. However, several aspects, such as when sirenians and seagrasses arrived to Australia and the seemingly late arrival of seagrasses to South America and the Eastern Pacific, still need further investigation.

Using a database of 43 generic and 94 species-level taxa, we compare the taxonomic diversity and patterns of morphological disparity in mosasaurs with sea level, sea surface temperature, and stable carbon isotope curves for the Upper Cretaceous to explore factors that may have influenced their evolution. No single factor unambiguously accounts for all radiations, diversification, and extinctions; however, the broader patterns of taxonomic diversification and morphological disparity point to niche differentiation in a "fishing up" scenario under the influence of "bottom-up" selective pressures. The most likely driving force in mosasaur evolution was high productivity in the Late Cretaceous, driven by tectonically controlled sea levels and climatically controlled ocean stratification and nutrient delivery. When productivity collapsed at the end of the Cretaceous, coincident with bolide impact, mosasaurs became extinct. Abstract Copyright (2014) Elsevier, B.V.

Odontocetes are unique among marine mammals in two important respects: 1) they use echolocation; 2) at least three lineages have independently evolved obligate freshwater habits from marine ancestries. Freshwater odontocetes include the so-called "river dolphins," a paraphyletic group that each evolved convergent external morphological characters that distinguish them from oceanic dolphins (Delphinoidea). In addition to their convergent external morphology, "river dolphins" all have echolocation that use one peak (narrow-band) frequency around 100 kHz, compared to oceanic delphinoids which use a two peak (bimodal) frequency ranging from 40 to 140 kHz. The differences in echolocation suggest that the sensory systems responsible for detecting these different sound frequencies should also differ, although quantitative assessments of the cetacean hearing system remain understudied and taxonomically undersampled. To test if ear bone morphology reflects underlying environmentally driven differences in echolocation ability, we assembled a dataset of odontocete periotics (n=114) from extant and fossil species. We examined 18 external and three internal linear periotic measurements, the latter of which were examined using cone-beam scanning tomography. Results from multivariate canonical ordination analyses show that periotic height, periotic thickness and pars cochlearis width collectively explain the largest amount of interspecific variation in our dataset. Because these particular ear bone measurements correspond to acoustic hearing ranges, we propose that they are also proxies for environmental preference (i.e., marine, freshwater and intermediate habitats) and may be useful for deciphering environmental preferences of extinct odontocetes.

The most successful, in terms of diversity and evolutionary duration, is the Sphenisciformes, or penguins, which still thrive in Southern Hemisphere waters. Three other groups are now extinct: Plotopteridae (Pelecaniformes); Mancallinae (Charadriiformes), or Lucas auks; and Pinguinus (Charadriiformes), or the Great Auk. Two clades include large species, the Plotopteridae, and the Sphenisciformes, in which extinct "giant" forms reached lengths and masses much larger than the living Aptenodytes forsteri (Emperor penguin). The extinction of flightless wing-propelled divers, especially giant forms, in the Northern and Southern Hemispheres has been linked to competitive displacement by co-evolving marine mammals. Such an idea is here assessed via taxonomic diversity (i.e., richness) trends from the fossil record reported in the Paleobiology Database. At global to basin scales, flightless divers and marine mammals indeed show contrasting patterns of diversity from the Chattian to the Aquitanian (late Oligocene to early Miocene: 28.4-20.43 Ma); diving birds decrease in diversity with increase in marine mammal diversity, especially Odontoceti. Long-term patterns are not compositional and do not result from scaling effects. Dietary overlap presumably played an important role in any competition, but this aspect is difficult to demonstrate. Marine mammals have similar diversity patterns to each other in both global and regional trends, implying a role for common evolutionary drivers as suggested previously for the evolution of crown Cetacea (or Neoceti). Flightless divers lack common diversity patterns, and show only partial negative correlations, as well as partial similarities, with marine mammal diversity trends. Thus, the evolution of flightless divers was probably governed by a mix of factors, rather than dominated by either physical or biotic drivers. Abstract Copyright (2014) Elsevier, B.V.

Consistent with prior studies, CAIs are characterized by significant depletions in Pd relative to the other HSE, while the other HSE are in generally bulk chondritic relative abundances. The depletions in Pd can be linked with initial formation of CAIs via condensation, or subsequent processing by evaporative processes. Chondrules generally have relative HSE patterns similar to CAIs, although they have lower absolute abundances. Palladium depletions in chondrules may reflect solid metal-liquid metal fractionation at the time of formation, or alternatively, be the result of processes that acted on precursor materials. Matrix samples have nearly chondritic absolute abundances of all HSE measured. Consequently, matrix is the only major chondritic component examined here that shows no relative depletion in Pd. Mass balance suggests the existence of an unidentified Pd-rich carrier, although it is possible that the dataset presented here is too limited to represent typical HSE abundances of some chondritic components (e.g., chondrules). The (super 187) Re- (super 187) Os isotopic systematics of only six out of twenty-four Allende chondritic components analyzed plot within uncertainties of a 4568 Ma primordial reference isochron. The deviations from the expected isochron most likely reflect late-stage, open-system behavior within the last 2 billion years, and, in some cases, could even have resulted from terrestrial alteration. The open-system behavior is most readily observed in small, millimeter-size sub-samples of Allende, consistent with Re and/or Os mobility on that scale. Abstract Copyright (2014) Elsevier, B.V.

A number of formal patterns can be identified and a range of meanings, but the maximal system in these languages seems to have two distinct types, usually with some allomorphy, and perhaps some less common subtypes. The same type and even the same stem may have two or three possible meanings. Reduplication in the Delaware languages (Munsee and Unami), in contrast, while morphologically similar to the patterns found in the other languages, has five distinct basic types, two of them with formal subtypes, and a broad range of meanings and grammatical functions.

However, for migratory birds, little is known about the acquisition and maintenance of colorful plumage during the nonbreeding period. Winter habitat could influence the quality of colorful plumage, ultimately carrying over to influence sexual selection and social interactions during the breeding period. In addition to the annual growth of colorful feathers, feather loss from agonistic interactions or predator avoidance could require birds to replace colorful feathers in winter or experience plumage degradation. We hypothesized that conditions on the wintering grounds of migratory birds influence the quality of colorful plumage. We predicted that the quality of American redstart (Setophaga ruticilla) tail feathers regrown after experimental removal in Jamaica, West Indies, would be positively associated with habitat quality, body condition, and testosterone. Both yearling (SY) and adult (ASY) males regrew feathers with lower red chroma, suggesting reduced carotenoid content. While we did not observe a change in hue in ASY males, SY males shifted from yellow to orange plumage resembling experimentally regrown ASY feathers. We did not observe any effects of habitat, testosterone, or mass change. Our results demonstrate that redstarts are limited in their ability to adequately replace colorful plumage, regardless of habitat, in winter. Thus, feather loss on the nonbreeding grounds can affect social signals, potentially negatively carrying over to the breeding period. We examined the production of colorful feathers known to play a role in sexual selection in a migratory bird while on its tropical wintering grounds. Regardless of habitat and physiological condition, adult males experienced a reduction in the color quality in replaced feathers. Our findings illustrate how visual signals can be limited by the ability of individuals to maintain their quality throughout the year, and for migratory animals, across multiple locations.

The assemblages are dominated by tropical shallow and deep water chondrichthyans, suggesting paleoenvironments associated with a short platform shelf bordering a deep margin. These assemblages are the most diverse shark and ray association known from the Tropical Central Eastern Pacific Ocean in the South American coastal basin, and provide new information on the paleoecology and paleodiversity of Neogene chondrichthyans.

However, changes from relative food self-provisioning to full dependence on one cash crop and from a complex mosaic of agricultural fields, fallows and forest patches to a homogenous landscape of cashew agroforests impacts both the natural environment and livelihoods. This article on the demise of shifting cultivation in the tropics contributes to the growing body of scholarship on land use-cover change (LUCC) and its multiplex global, national and local drivers, varying across time and space. Further, we argue that instead of adopting an approach exclusively focused on parks, conservation-oriented external interventions should engage with farmers in the development of innovations that both preserve forest ecosystems and enhance food security.

This is a partial test of the "sodium ecosystem respiration" (SER) hypothesis that posits Na is critical for consumers but not plants, that Na shortfall is more likely on highly weathered soils inland from oceanic aerosols, and that this shortfall results in decreased decomposer activity. We fertilized 4 X 4 m plots twice a month for a year with quantities of Na comparable to those falling on a coastal tropical rainforest. Decomposition rates of four substrates were consistently higher on +NaCl plots by up to 70% for cellulose, and 78%, 68%, and 29% for three woods of increasing percentage lignin. The density of termite workers averaged 17-fold higher on +NaCl plots; fungal biomass failed to differ. After controlling for temperature and precipitation, which co-limit gross primay productivity (GPP) and ecosystem respiration (ER), these results suggest that Na shortfall is an agent enhancing the storage of coarse woody debris in inland tropical forests.

Phylogenetic density-dependent survival of seedlings in a tropical forest AN - 1547853211; 20222844 AB - A complex set of interactions among neighbors influences plant performance and community structure. Understanding their joint operation requires extensive information on species characteristics and individual performance. We evaluated first-year survival of 35 719 tropical forest seedlings of 222 species and 15 annual cohorts relative to the density of conspecific and heterospecific neighbors and the phylogenetic similarity of heterospecific neighbors. Neighbors were from two size classes, and size asymmetric interactions provided insight into likely mechanisms. Large heterospecific and conspecific neighbors reduced seedling survival equally, suggesting resource competition rather than host-specific enemies as a mechanism. In contrast, much stronger negative conspecific effects were associated with seedling neighbors capable of limited resource uptake, suggesting shared pests rather than competition as the mechanism. Survival improved, however, near phylogenetically similar heterospecific neighbors, suggesting habitat associations shared among closely related species affect spatial patterns of performance. Improved performance near phylogenetically similar neighbors is an emerging pattern in the handful of similar studies.

Our ability to accurately characterize patterns of migratory connectivity is often limited by the spatial resolution of the data, but recent advances in probabilistic assignment approaches have begun pairing stable isotopes with other sources of data (e.g., genetic and mark-recapture) to improve the accuracy and precision of inferences based on a single marker. Here, we combine stable isotopes and geographic variation in morphology (wing length) to probabilistically assign Wood Thrush (Hylocichla mustilena) captured on the wintering grounds to breeding locations. In addition, we use known-origin samples to validate our model and assess potentially important impacts of isotopic and morphological covariates (age, sex, and breeding location). Our results show that despite relatively high levels of mixing across their breeding and nonbreeding ranges, moderate levels of migratory connectivity exist along an east-west gradient. In addition, combining stable isotopes with geographic variation in wing length improved the precision of breeding assignments by 10% and 37% compared to assignments based on isotopes alone or wing length alone, respectively. These results demonstrate that geographical variation in morphological traits can greatly improve estimates of migratory connectivity when combined with other intrinsic markers (e.g., stable isotopes or genetic data). The wealth of morphological data available from museum specimens across the world represents a tremendously valuable, but largely untapped, resource that is widely applicable for quantifying patterns of migratory connectivity.

These habitats differ considerably in altitude, which has a pronounced effect on forest ecology. Although all gorillas are obligate terrestrial knuckle-walking quadrupeds, those that live in lowland habitats eat fruits and climb more often than do those living in highland habitats. Here we test the hypothesis that gorilla talus morphology falls along a morphocline that tracks locomotor function related to a more inverted or everted foot set. This proposed morphocline predicts that gorillas living in lowland habitats may have a talocrural joint configured to facilitate a more medially oriented foot during climbing, suggesting that they may be more adaptively committed to arboreality than gorillas living in highland habitats. To quantify the relative set of the foot in gorillas, we chose two three-dimensional measurements of the talocrural joint: mediolateral curvature of the trochlea and relative surface area of the lateral malleolus. Our results show that, in comparison to their eastern counterparts, western gorillas have talar features that reflect a more medially directed sole of the foot. This morphology likely facilitates foot placement in a wider range of positions and minimization of shearing stresses across the joint when the foot is loaded on more curved or vertically oriented substrates as occurs during climbing and other arboreal behaviors. In contrast, eastern gorilla talar morphology is consistent with habitual placement of the foot with the sole directed more inferiorly, suggesting more effective loading during plantigrade push-off on terrestrial substrates.

Lupinus aridorum McFarlin ex Beckner (Fabaceae) is a critically endangered plant known only from a few locations in imperiled Florida scrub habitat and nothing is known about its preferred microhabitat. Our goals were threefold. First, determine whether L. aridorum has multiple cytotypes because this can influence its spatial distribution. Second, measure how microhabitat characteristics at locations supporting wild L. aridorum vary from random locations, which will provide information about microhabitat characteristics that influence the spatial distribution of individuals. Third, measure whether microhabitat characteristics differ between locations supporting wild or introduced plants, which will provide information about the realized and fundamental niche. Our research determined that L. aridorum is diploid and grew, on average, in areas closer to trees and shrubs, with lower soil moisture, and with a greater mixture of detritus than random locations. Some microhabitat characteristics at locations where L. aridorum were introduced were similar to microhabitat supporting wild L. aridorum, but multiple soil characteristics differed as did the plant community, which contained more nonnative plant species near introduced plants. Therefore, the realized niche is narrower than the fundamental niche. Overall, information about the microhabitat of L. aridorum can be used to design appropriate management programs to conserve and restore populations of this plant species and species that occupy a similar niche in imperiled Florida scrub.

AN - 1511822512; 24508651 AB - Two studies were conducted to understand sperm cryosensitivity in an endangered equid, the Przewalski's horse (Equus ferus przewalski), while testing the cryoprotectant ability of formamides. The first assessed the toxicity of permeating cryoprotectants (glycerol, methylformamide [MF] and dimethylformamide [DMF]) to Przewalski's horse spermatozoa during liquid storage at 4°C. The second examined the comparative influence of three diluents (with or without formamides) on cryosurvival of sperm from the Przewalski's versus domestic horse. When Przewalski's horse spermatozoa were incubated at 4°C in INRA 96 with differing concentrations of glycerol, MF or DMF or a combination of these amides, cells tolerated all but the highest concentration (10% v/v) of MF alone or in combination with DMF, both of which decreased (P0.05) between the Przewalski's (67%, 84%, respectively) and domestic (66%, 76%) horse donors. Sperm from both species were diluted in lactose-EDTA-glycerol (EQ), Botu-Crio (BOTU; a proprietary product containing glycerol and MF) or SM (INRA 96 plus 2% [v/v] egg yolk and 2.5% [v/v] MF and DMF) and then frozen over liquid nitrogen vapor. After thawing, the highest values recovered for total and progressive sperm motility, acrosomal integrity and mitochondrial membrane potential were 42.4%, 21.8%, 88.7% and 25.4CN (CN=mean JC-1 fluorescence intensity/cell on a channel number scale), respectively, in the Przewalski's and 49.3%, 24.6%, 88.9% and 25.8CN, respectively, in the domestic horse. Although sperm progressive motility and acrosome integrity did not differ (P>0.05) among treatments across species, mitochondrial membrane potential was higher (P<0.05) in both species using EQ compared to BOTU or SM media. Additionally, Przewalski's stallion sperm expressed higher (P<0.05) post-thaw total motility in BOTU and SM compared to EQ, whereas there were no differences among freezing diluents in the domestic horse. In summary, Przewalski's stallion sperm benefit from exposure to either MF or DMF as an alternative cryoprotectant to glycerol. Overt sperm quality appears similar between the Przewalski's and domestic horse, although the total motility of cells from the former appears more sensitive to certain freezing diluents. Nonetheless, post-thaw motility and acrosomal integrity values for Przewalski's horse spermatozoa mimic findings in the domestic horse in the presence of INRA 96 supplemented with 2% (v/v) egg yolk and a combined 2.5% concentration of MF and DMF.

In the aftermath of such collisions, the surface of the surviving planet is very hot and potentially detectable. Here we explore the atmospheric chemistry, photochemistry, and spectral signatures of post-giant-impact terrestrial planets enveloped by thick atmospheres consisting predominantly of CO (sub 2) and H (sub 2) O. The atmospheric chemistry and structure are computed self-consistently for atmospheres in equilibrium with hot surfaces with composition reflecting either the bulk silicate Earth (which includes the crust, mantle, atmosphere, and oceans) or Earth's continental crust. We account for all major molecular and atomic opacity sources including collision-induced absorption. We find that these atmospheres are dominated by H (sub 2) O and CO (sub 2) , while the formation of CH (sub 4) and NH (sub 3) is quenched because of short dynamical timescales. Other important constituents are HF, HCl, NaCl, and SO (sub 2) . These are apparent in the emerging spectra and can be indicative that an impact has occurred. The use of comprehensive opacities results in spectra that are a factor of two lower brightness temperature in the spectral windows than predicted by previous models. The estimated luminosities show that the hottest post-giant-impact planets will be detectable with near-infrared coronagraphs on the planned 30 m class telescopes. The 1-4 mu m will be most favorable for such detections, offering bright features and better contrast between the planet and a potential debris disk. We derive cooling timescales on the order of 10 (super 5-6) yr on the basis of the modeled effective temperatures. This leads to the possibility of discovering tens of such planets in future surveys.

Here we describe Anzu wyliei gen. et sp. nov., a new taxon of large-bodied caenagnathid based primarily on three well-preserved partial skeletons. The specimens were recovered from the uppermost Cretaceous (upper Maastrichtian) Hell Creek Formation of North and South Dakota, and are therefore among the stratigraphically youngest known oviraptorosaurian remains. Collectively, the fossils include elements from most regions of the skeleton, providing a wealth of information on the osteology and evolutionary relationships of Caenagnathidae. Phylogenetic analysis reaffirms caenagnathid monophyly, and indicates that Anzu is most closely related to Caenagnathus collinsi, a taxon that is definitively known only from a mandible from the Campanian Dinosaur Park Formation of Alberta. The problematic oviraptorosaurs Microvenator and Gigantoraptor are recovered as basal caenagnathids, as has previously been suggested. Anzu and other caenagnathids may have favored well-watered floodplain settings over channel margins, and were probably ecological generalists that fed upon vegetation, small animals, and perhaps eggs.

The lithosphere, the mechanically strong outer layer of a planet, responds to growing edifice loads by flexing. The shape of this lithospheric flexure and the resulting stress state exert critical influences on the structure of the evolving edifices, which in turn feed back into the flexural response. Flexural subsidence of the lithosphere forms topographical moats surrounding volcanoes that are partially to completely filled by landslide debris, volcaniclastic materials and sediments, or by relatively flat aprons of volcanic flows. Flexure creates a characteristic "dipole" state of stress that influences subsequent magma ascent paths and chamber dynamics in the lithosphere. Compression in the upper lithosphere can inhibit magma ascent and favour the development of oblate magma chambers or sill complexes. This compression can be transferred into the edifice unless a decollement allows the volcano base to slip over the underlying lithosphere; generally, basal decollements are found to operate via high pore-fluid pressure in a clay sediment-based layer. Volcanoes lacking such a layer, regardless of the thickness of the basal sediments, lack basal decollements and, thus, tend to be limited in size by compressive stresses adverse to magma ascent.

However, with no knowledge of the homeland of R. exulans, the place of origin of this human-commensal relationship is unknown. We conducted a mitochondrial DNA phylogeographic survey of R. exulans diversity across the potential natural range in mainland and Island Southeast Asia in order to establish the origin of this human-commensal dyad. We also conducted allozyme electrophoresis on samples from ISEA to obtain a perspective on patterns of genetic diversity in this critical region. Finally, we compared molecular genetic evidence with knowledge of prehistoric rodent faunas in mainland and ISEA. We find that ISEA populations of R. exulans contain the highest mtDNA lineage diversity including significant haplotype diversity not represented elsewhere in the species range. Within ISEA, the island of Flores in the Lesser Sunda group contains the highest diversity in ISEA (across all loci) and also has a deep fossil record of small mammals that appears to include R. exulans. Therefore, in addition to Flores harboring unusual diversity in the form of Homo floresiensis, dwarfed stegodons and giant rats, this island appears to be the homeland of R. exulans.

We analyze a rich, ten-year collection of optical/infrared (OIR) time-series data in conjunction with all available contemporaneous X-ray data collected by the All-Sky Monitor and Proportional Counter Array detectors aboard the Rossi X-ray Timing Explorer. A cross-correlation analysis reveals an X-ray lag of approximately 2 weeks. Motivated by this result, we develop a model that reproduces the complex OIR light curves of LMC X-3. The model is comprised of three components of emission: stellar light, accretion luminosity from the outer disk inferred from the time-lagged X-ray emission, and light from the X-ray-heated star and outer disk. Using the model, we filter a strong noise component out of the ellipsoidal light curves and derive an improved orbital period for the system. Concerning accretion physics, we find that the local viscous timescale in the disk increases with the local mass accretion rate; this in turn implies that the viscosity parameter alpha decreases with increasing luminosity. Finally, we find that X-ray heating is a strong function of X-ray luminosity below approximately 50% of the Eddington limit, while above this limit X-ray heating is heavily suppressed. We ascribe this behavior to the strong dependence of the flaring in the disk upon X-ray luminosity, concluding that for luminosities above approximately 50% of Eddington, the star lies fully in the shadow of the disk.

Although past studies have evaluated various components of this behavior, much remains unknown about many basic aspects of roost dynamics. To learn more about communal roosting I examined roost establishment, recruitment, roost-mate resource use, roosting participation in a population, and roost arrival, departure, and perch preferences in natural populations of Heliconius erato petiverana in Panama. My observations suggest that 1) younger butterflies are recruited more readily than older butterflies, 2) roosts are first established by a single butterfly roosting consecutively in the same location that later recruits butterflies, 3) males depart roosts earlier than females in the morning, 4) older butterflies tend to roost on the same perch in the same roost every night, 5) roost-mates share the same resource traplines, and 6) most butterflies in a population participate in roosts. These observations present an improved portrait of Heliconius roosting and raise several new questions about this behavior.

We measured loss on ignition (LOI), carbon to nitrogen ratio (C:N), diatom abundance, total nitrogen (TN), total phosphorus (TP), TN:TP ratio, and carbon and nitrogen isotopes (delta (super 13) C and delta (super 15) N) in an 83-cm sediment core to track recent trophic status changes in Beaver Reservoir, Northwest Arkansas, USA. Measurements showed that LOI, TN, TP and diatom abundance increased significantly from the bottom to the top of the core (p < 0.001). The C:N ratio and delta (super 13) C indicated a predominantly algal source for organic matter in the sediments. Increases in TN and TP were positively correlated with human population growth (p < 0.01) and the TN:TP ratio recorded a shift from phosphorus to nitrogen limitation around 1990. This shift may have encouraged cyanobacterial growth that caused episodes of taste and odor problems in the reservoir. This study suggests that despite concerns about sediment dating and disturbance, reservoir sediments can provide valuable information on past water quality changes.

Recent geological surveys have provided new constraints on timing of the seaway shoaling, while neodymium isotopic (epsilon (sub Nd) ) data measured on fossil teeth, debris, and ferromanganese crusts have helped define the history of water masses in the region. Here we provide the first 3-D simulations of epsilon (sub Nd) responses to the shoaling seaway. Our model suggests that a narrow and shallow seaway is sufficient to affect interoceanic circulation, that inflow/outflow balance between the Caribbean and the Antilles responds nonlinearly to sill depth, and that a seaway narrower than 400 km is consistent with an active Atlantic meridional overturning circulation during the late Miocene. Simulated epsilon (sub Nd) values in the Caribbean confirm that inputs from radiogenic Pacific waters in the Caribbean decrease as the seaway shoals. Despite model limitations, a comparison between our results and epsilon (sub Nd) values recorded in the Caribbean helps constrain the depth of the Central American Seaway through time, and we infer that a depth between 50 and 200 m could have been reached 10 Ma ago.

Although there is not a local peak of extinction every 27 Myr, an excess of the fraction of genus extinction by interval follows a 27-Myr timing interval and differs from a random distribution at the p approximately 0.02 level. A 27-Myr periodicity in the spectrum of interval lengths no longer appears, removing the question of a possible artifact arising from it. Using a method originally developed in Bambach (2006) we identify 19 intervals of marked extinction intensity, including mass extinctions, spanning the last 470 Myr (and with another six present in the Cambrian) and find that ten of the 19 lie within + or -3 Myr of the maxima in the spacing of the 27-Myr periodicity, which differs from a random distribution at the p = 0.004 level. These 19 intervals of marked extinction intensity also preferentially occur during decreasing diversity phases of a well-known 62-Myr periodicity in diversity (16 of 19, p = 0.002). Both periodicities appear to enhance the likelihood of increased severity of extinction, but the cause of neither periodicity is known. Variation in the strength of the many suggested causes of extinction coupled to the variation in combined effect of the two different periodicities as they shift in and out of phase is surely one of the reasons that definitive comparative study of the causes of major extinction events is so elusive.

Understanding species spatial occurrence patterns and their environmental dependence is one of the fundamental goals in ecology and evolution. Often, occurrence models are built with presence-only data because absence data are unavailable. We compare the strengths and limitations of the recently developed presence-only modelling method, Maxlike, with the more widely used Maxent. 2. In spite of disparities highlighted by the developers of Maxlike and Maxent, we show approximate formal relationships between the parameters of Maxlike and Maxent for two scenarios to illustrate their similarity. Using case studies based on real and simulated data, we show how these similarities manifest in practice. 3. We find more similarities than differences between Maxlike and Maxent, including coefficient values, predicted spatial distributions, similarity to presence-absence models, predictive performance and ranking the predicted suitability of cells. Maxlike reliably predicted absolute occurrence probabilities for very large data sets on landscapes where occurrence probability approximately spanned [0,1]. For smaller data sets, the uncertainty in predicted occurrence probability by Maxlike was very large, due to the inherent limitations of presence-only data. In contrast, Maxent is constrained to predicting relative occurrence probabilities or relative occurrence rates unless it is provided with additional information from presence-absence data. Both models can reliably predict relative differences in occurrence probability. 4. The choice of which model to use depends partly on sampling assumptions, which we discuss in detail. Due to limitations of presence-only data, ecologists should typically focus on interpretations relying on relative differences in occurrence probability or relative occurrence rates. We discuss how to remedy a number of concerns about the use of Maxent and how to avoid some potential pitfalls with Maxlike - particularly related to high variance predictions. We conclude that both methods are similarly valuable for understanding and predicting species' distributions in terms of relative differences in occurrence probability when the models are specified carefully.

We present here a detailed molecular phylogenetic analysis of the Hawaiian species of this genus and compare the results with the other genera of Hawaiian Rutaceae, Platydesma and Zanthoxylum. Four nuclear and two plastid markers were sequenced, with the goals of untangling phylogenetic relationships, inferring biogeographic events and comparing patterns of distribution among the three genera. Our results show that there were two colonization events (Melicope+Platydesma, and Zanthoxylum) to the Hawaiian Islands, that Hawaiian Rutaceae have an Asian, Australian or Pacific origin and that there were two independent colonization events of Hawaiian Melicope lineages to the Marquesas Islands. The two most widely distributed Hawaiian Melicope spp. are not monophyletic and the current subgeneric classification of Hawaiian Melicope is highly artificial. On the Hawaiian Islands, Melicope and Zanthoxylum show contrasting biogeographic patterns, suggesting different patterns of dispersal. Melicope has a high percentage of single-island endemics suggesting low dispersal ability, whereas Zanthoxylum taxa tend to occur across multiple islands. copyright 2013 The Linnean Society of London, Botanical Journal of the Linnean Society, 2014, 174, 425-448.

A total of 18 staple foods that comprise 97% of the annual dietary intake of the mountain gorilla (Gorilla beringei) were analyzed for fatty acid concentrations. Fruits and herbaceous leaves comprise the majority of the diet, with fruits generally having a higher mean percentage of fat (of dry matter; DM), as measured by ether extract (EE), than herbaceous leaves (13.0%  ; SD 13.0% vs. 2.3 SD 0.8%). The mean daily EE intake by gorillas was 3.1% (DM). Fat provided ≈14% of the total dietary energy intake, and ≈22% of the dietary non-protein energy intake. Saturated fatty acids accounted for 32.4% of the total fatty acids in the diet, while monounsaturated fatty acids accounted for 12.5% and polyunsaturated fatty acids (PUFA) accounted for 54.6%. Both of the two essential PUFA, linoleic acid (LA, n-6) and α-linolenic acid (ALA, n-3), were found in all of the 17 staple foods containing crude fat and were among the three most predominant fatty acids in the diet: LA (C18:2n-6) (30.3%), palmitic acid (C16:0) (23.9%), and ALA (C18:3n-3) (21.2%). Herbaceous leaves had higher concentrations of ALA, while fruit was higher in LA. Fruits provided high amounts of fatty acids, especially LA, in proportion to their intake due to the higher fat concentrations; despite being low in fat, herbaceous leaves provided sufficient ALA due to the high intake of these foods. As expected, we found that wild mountain gorillas consume a diet lower in EE, than modern humans. The ratio of LA:ALA was 1.44, closer to agricultural paleolithic diets than to modern human diets.

Secondary contact zones, in particular, present a partial separation of the original divergence mechanisms and the subsequent genomic architecture of reproductive isolation (or lack thereof). The spatial context of secondary contact and its consequent effect on dispersal play vital roles on the contact's outcome. In a hybrid complex between two towhee species in Mexico, Pipilo maculatus and Pipilo ocai, two major hybrid gradients provide natural replicates for comparison. However, genetic analyses demonstrate significant divergence between geographically separate parental populations of each species and divergence of populations within each hybrid zone. The two hybrid transects (Teziutlan and Transvolcanic) are distinct and evidence suggests allelic introgression both across the species boundary and between the two transects. Habitat corridors for dispersal represent functional connectivity hotspots where the two transects meet. Both habitat connectivity and genetic differentiation between geographically disparate parental populations appear to influence the dynamics of gene flow across the hybrid gradients. In southern sympatric populations (Mt. Orizaba and Oaxaca) where morphological evidence for hybridization is scarce, opposing species' alleles appear to traverse through the hybrid zones rather than arising from cryptic local hybridization. These results illustrate the importance of environmentally mediated gene flow in the context of secondary contact as an important force influencing evolutionary trajectory.

The dune field was selected for its position in a likely complex, multi-directional wind regime. Results indicate that four main winds are responsible for simultaneous construction of the dune field, including along-chasma winds from the ESE, winds blowing down a nearby re-entrant from the NE, winds blowing down the adjacent chasma wall from the NW, and chasma floor winds from the SW. Each wind represents a transport vector that dominates dune morphology at its respective edge of the dune field, such that the central axis of the dune field reflects the convergence of the three most prominent winds (ESE, NW, and SW). The Mars Regional Atmospheric Modeling System (MRAMS) was run at twelve times throughout the martian year to provide context for the local wind patterns. Potential sand fluxes calculated from MRAMS output show that three major air flows from the ENE-E, NNE-NE, and NNW-N converge near the location of the dune field. These flows likely correspond to the ESE, NE, and NW winds identified from IMGBNT analysis, respectively. MRAMS output shows that the flows with major northerly components are produced by larger-scale Hadley return flow constructively combining with nighttime downslope winds; the flow with a major easterly component is likely produced by equatorial easterly "trade" winds constructively combining with the diurnal tide and/or local topography. Although the model correctly predicts the major elements of the local wind pattern, some aspects are either over- or underrepresented, demonstrating the value of using aeolian morphological analysis to conclusively constrain the major sand-moving winds on Mars. Overlapping High Resolution Imaging Experiment (HiRISE) images of barchanoid dunes at the northernmost edge of the dune field indicate that these dunes are currently migrating southward at approximately 5 m/Mars year ( approximately 2.6 m/Earth year); the direction of migration is consistent with both MRAMS predictions in this location and the NW/NE winds found from IMGBNT analysis. Dune morphology suggests that sand in the northwestern part of the dune field is likely to be derived from the adjacent chasma wall to the north and northwest, and sand in the southeastern part of the dune field was probably transported from farther east along the main chasma floor.

The recently released south pole (SP) portion (MC-30) of MGD3 adds approximately 60,000 km (super 2) of medium to large-size dark dune fields and approximately 15,000 km (super 2) of sand deposits and smaller dune fields to the previously released equatorial (EQ, approximately 70,000 km (super 2) ), and north pole (NP, approximately 845,000 km (super 2) ) portions of the database, bringing the global total to approximately 975,000 km (super 2) . Nearly all NP dunes are part of large sand seas, while the majority of EQ and SP dune fields are individual dune fields located in craters. Despite the differences between Mars and Earth, their dune and dune field morphologies are strikingly similar. Bullseye dune fields, named for their concentric ring pattern, are the exception, possibly owing their distinctive appearance to winds that are unique to the crater environment. Ground-based wind directions are derived from slipface (SF) orientation and dune centroid azimuth (DCA), a measure of the relative location of a dune field inside a crater. SF and DCA often preserve evidence of different wind directions, suggesting the importance of local, topographically influenced winds. In general however, ground-based wind directions are broadly consistent with expected global patterns, such as polar easterlies. Intriguingly, between 40 degrees S and 80 degrees S latitude both SF and DCA preserve their strongest, though different, dominant wind direction, with transport toward the west and east for SF-derived winds and toward the north and west for DCA-derived winds.

The shapes of the profiles reveal a progression from immature to transitional to mature characteristics moving up the dune. When scaled by the basal width along each profile, shape characteristics can be compared for profiles whose horizontal scales differ by orders of magnitude. The comparison of width-scaled Bruneau Dunes profiles to similarly scaled profiles of Transverse Aeolian Ridges (TARs) on Mars indicates that many TARs are likely similar to transitional or mature reversing sand dunes.

We find that the bedform wavelength ( approximately 1-5 m) varies as the reciprocal of density. The observed wavelengths and wavelength dependence are compared with three recent models of bedform spacing. The results are consistent with the expected increase in threshold friction speed and saturation drag length with elevation. The observations lend support to the expectation that such bedforms on Venus or Titan are too small to be observed in present data.

We present a method to apply the rule of MGBNT and its inverse (IMGBNT) from analysis of aeolian dune crestlines derived from aerial imagery. Although the solutions to IMGBNT analysis are non-unique, the possible transport vectors influencing bedform morphology can often be constrained by making inferences regarding bedform type (e.g., transverse, oblique, or longitudinal), resultant drift direction, and the ratio of transport vector magnitudes. The technique is demonstrated on the Great Sand Dunes, located in Colorado, USA. This dune field has a wide array of dune morphologies; eight crestline sets were identified and mapped. IMGBNT analysis and the subsequent constraint of possible solutions suggests that transport vectors from the southeast and southwest, with a SE:SW transport ratio of approximately 1:2, produce oblique north-south oriented dunes that dominate the main dune field. These results compare favorably with MGBNT analysis of meteorologic measurements from three stations located adjacent to the Great Sand Dunes, which predict dune types and orientations similar to those observed in their vicinity.

During several of the 93 Titan fly-bys performed by Cassini, the radar collected a large amount of data observing many dune fields in multiple modes such as SAR, Altimeter, Scatterometer and Radiometer. Understanding dune characteristics, such as shape and height, will reveal important clues on Titan's climatic and geological history providing a better understanding of aeolian processes on Earth. Dunes are believed to be sculpted by the action of the wind, weak at the surface but still able to activate the process of sand-sized particle transport. This work aims to estimate dunes height by modeling the shape of the real Cassini Radar Altimeter echoes. Joint processing of SAR/Altimeter data has been adopted to localize the altimeter footprints overlapping dune fields excluding non-dune features. The height of the dunes was estimated by applying Maximum Likelihood Estimation along with a non-coherent electromagnetic (EM) echo model, thus comparing the real averaged waveform with the theoretical curves. Such analysis has been performed over the Fensal dune field observed during the T30 flyby (May 2007). As a result we found that the estimated dunes' peak to trough heights difference was in the order of 60-120 m. Estimation accuracy and robustness of the MLE for different complex scenarios was assessed via radar simulations and Monte-Carlo approach. We simulated dunes-interdunes different composition and roughness for a large set of values verifying that, in the range of possible Titan environment conditions, these two surface parameters have weak effects on our estimates of standard dune heights deviation.

These ripples are composed of fine basaltic sand ( approximately 100 mu m diameter) and their average wavelength and height are 10 cm and 1 cm, respectively. Present theories on the transition between saltation and suspension predict that such light particles are suspended by turbulence at the fluid threshold, which is the minimum wind speed required to initiate saltation. Consequently, the existence of these approximately 100 mu m ripples on Mars indicates that either current suspension theories are incorrect, or that saltation can take place at wind speeds substantially below the fluid threshold. Indeed, recent studies point to the occurrence of hysteresis in martian saltation. That is, once initiated, hysteresis can be maintained at much lower wind speeds than the fluid threshold. We investigated the possible role of hysteresis in the formation of fine-grained ripples on Mars by coupling, for the first time, a detailed numerical saltation model (COMSALT) with a dynamic model for sand ripple formation. The results from the coupled model indicate that ripples with properties similar to those observed at Eagle Crater can be developed by the impact mechanism at shear velocities far below the fluid threshold. These findings are consistent with the occurrence of hysteresis in martian saltation, and support the hypothesis that hysteresis plays a role in the surprisingly large sand mobility observed at several locations on Mars.

Several recent studies have shown that the erg's thermal properties are consistent with normal basaltic sand overlying shallow ground ice or ice-cemented sand. Our findings bolster that conclusion by thoroughly characterizing the thermal behavior of the erg, demonstrating that other likely forms of physical heterogeneity play only a minor role, and obviating the need to invoke exotic materials. Thermal inertia as calculated from orbital temperature observations of the dunes has previously been found to be more consistent with dust-sized materials than with sand. Since theory and laboratory data show that dunes will only form out of sand-sized particles, exotic sand-sized agglomerations of dust have been invoked to explain the low values of thermal inertia. However, the polar dunes exhibit the same darker appearance and color as that of dunes found elsewhere on the planet that have thermal inertia consistent with normal sand-sized basaltic grains, whereas Martian dust deposits are generally lighter and redder. The alternative explanation for the discrepancy as a thermal effect of a shallow ice table is supported by our analysis of observations from the Mars Global Surveyor Thermal Emission Spectrometer and the Mars Odyssey Thermal Emission Imaging System and by forward modeling of physical heterogeneity. In addition, our results exclude a uniform composition of dark dust-sized materials, and they show that the thermal effects of the dune slopes and bright interdune materials evident in high-resolution images cannot account for the erg's thermal behavior.

Over 7000 dune width and 7000 dune spacing measurements were obtained for linear dunes in regions across Saturn's moon Titan from images T21, T23, T28, T44 and T48 collected by the Synthetic Aperture RADAR (SAR) aboard the Cassini spacecraft in order to reconstruct the aeolian surface history of Titan. Dunes in the five study areas are all linear in form, with a mean width of 1.3 km and mean crest spacing of 2.7 km, similar to dunes in the African Saharan and Namib deserts on Earth. At the resolution of Cassini SAR, the dunes have the morphology of large linear dunes, and they lack evidence for features of compound or complex dunes. The large size, spacing and uniform morphology are all indicators that Titan's dunes are mature features, in that they have grown toward a steady state for a long period of time. Dune width decreases to the north, perhaps from increased sediment stabilization caused by a net transport of moisture from south to north, or from increased maturity in dunes to the south. Cumulative probability plots of dune parameters measured at different locations across Titan indicate there is a single population of intermediate-to-large-sized dunes on Titan. This suggests that, unlike analogous dunes in the Namib and Agneitir Sand Seas, dune-forming conditions that generated the current set of dunes were stable and active long enough to erase any evidence of past conditions.

Orientations of aeolian features such as bedforms and yardangs are controlled by the prevailing wind regime during the feature's formation. Therefore, observation of recently formed bedform orientations provides a way to probe Mars' recent wind regime and constrain/test general circulation models (GCMs). We collect statistical distributions of transverse bedform and yardang azimuths at nine sites on Mars, and compare measured feature orientations to those predicted by using vector wind field output from the MarsWRF GCM. We focus on layered deposits because their erodible nature makes them applicable to determination of Mars' modern wind regime. Our methods of mapping from the long-term wind field to predicted feature orientations include consideration of wind stress thresholds for sand movement to occur, sand flux equations, and the direction of maximum gross bedform-normal transport. We find that all methods examined typically agree with each other to within approximately 15 degrees , though there are some exceptions using high order wind stress weightings with multi-directional annual wind fields. Generally, use of higher wind stress thresholds produces improved matches to bedform orientations. Comparison of multiple yardang orientations to annually variable wind fields is accomplished by inspection of directional maxima in modelled wind vector frequency distributions. Yardangs match well to model predictions and sub-populations in close proximity to each other are shown to match individual directional maxima in GCM output for a single site, implying that topographic effects may produce very localised unidirectional wind fields unresolved by the GCM.

The possibility of significant triboelectric charging of sediments in Titan's low-conductivity environment is noted, and given Titan's low gravity electrostatic forces could substantially influence the saltation mechanics. Saltation paths are likely too short to permit observable ripples, while dunes may grow from an elemental size of approximately 1.5 m to a spacing of approximately 3 km, limited by the thickness of the atmospheric boundary layer. Most of Titan's dunes are of this size, indicating completed growth and that dividing sand volume by sand fluxes will yield only a lower limit on the dune age. Sand fluxes are estimated.

This high-latitude, cold-climate dune field is being studied as a planetary analog to improve our understanding of factors that may trigger debris flows on the lee slopes of martian aeolian dunes. Debris flows consisted of a sand and liquid water mixture that cascaded down the lee slopes of two barchanoid dunes on days when measured ground surface temperatures were below freezing. We hypothesize that relatively dark sand on snow caused local hot spots where solar radiation could be absorbed by the sand and conducted into the underlying snow, enabling meltwater to form and sand to be mobilized. This investigation provides insights into the interactions between niveo-aeolian deposition, slope aspect and insolation, thawing, and initiation of alluvial processes. These debris flows are morphologically similar to those associated with seasonal gullies or erosion tracks visible on the slopes of mid- to high-latitude dune fields in both martian hemispheres. Localized heating and thawing at scales too small for orbital sensors to identify may yield martian debris flows at current climate conditions.

As the Cassini mission, in orbit around Saturn since July 2004 and extended until May 2017, carries on, the high-resolution coverage of Titan's surface increases, revealing new dune fields and allowing refinements in the examination of their properties. In this paper, we present the joint analysis of Cassini's microwave and infrared global scale observations of Titan. Integrating within an up-to-date global map of Titan all the Cassini RADAR and VIMS (Visual and Infrared Mapping Spectrometer) images - the latter being empirically corrected for atmospheric scattering and surface photometry, from July 2004 through July 2013 and June 2010 respectively, we found very good qualitative and quantitative spatial matching between the geographic distribution of the dune fields and a specific infrared spectral unit (namely the "dark brown" unit). The high degree of spatial correlation between dunes and the "dark brown" unit has important implications for Titan's geology and climate. We found that RADAR-mapped dunes and the "dark brown" unit are similarly confined within the equatorial belt (+ or -30 degrees in latitudes) with an equivalent distribution with latitude, suggesting an increasing sediment availability and mobility at Titan's tropics relative to higher latitudes, compatible with the lower ground humidity predicted in equatorial regions by General Circulation Models. Furthermore, the strong correlation between RADAR-mapped dunes and the VIMS "dark brown" unit (72%) allows us to better constrain the total surface area covered by dune material, previously estimated from the extrapolation of the RADAR observations alone. According to our calculations, dune material cover 17.5 + or - 1.5% of Titan's surface area, equivalent to a total surface area of 14.6 + or - 1.2 million km (super 2) ( approximately 1.5 times the surface area of Earth's Sahara desert). The VIMS "dark brown" coloration of the dune material is here confirmed at large spatial scale. If the sand particle composition is dominated by solid organics produced in and settling from the atmosphere, as supported by our spectral modeling and by previous spectral analysis, microwave radiometric data and atmospheric modeling, dune fields are one of the major surface hydrocarbon reservoirs on Titan. Assuming two possible scenarios for the sand distribution (either the sand is (1) entirely trapped in dune landforms, or (2) trapped in dunes at places where dune landforms are firmly observed and in sand sheets elsewhere), we estimate the volume of hydrocarbons trapped in the dune sediment to be comprised between 1.7 and 4.4 X 10 (super 5) km (super 3) , corresponding to an average total mass of 230,000 GT, in comparison with approximately 4000-30,000 GT of hydrocarbons in the polar lakes and seas. This indicates a maximum age for the dune sediments of DF730-Myr, consistent with estimations of the ages of the current Titan's atmospheric methane and surface.

Using multi-frequency SIR-C/X-SAR radar scenes and topography obtained from the Shuttle Radar Topography Mission (SRTM), we were able to estimate reasonable values for the parameters describing the surface roughness of the dunes. As the linear dunes of the Great Sand Sea are relevant analogs for the linear dunes observed on Titan by the Cassini Radar instrument, these results were thus used as a starting point to simulate the radar response of Titan's dunes, as imaged by the Radar instrument onboard the Cassini spacecraft during the T8 flyby in October 2005. We show that a single surface scattering term is not sufficient to simulate the radar signal backscattered by the dunes on Titan: one has to add a diffuse scattering term, indicating that Titan's dunes are likely to have somewhat inhomogeneous internal structures related to porosity and/or internal layering. Our results also indicate that the dunes on Titan should be close to perfectly smooth, possibly because of the formation of smaller ripples than on Earth, plus smoothing resulting from precipitation events.

We follow an object-based approach in which the bedform crestlines are automatically mapped and characterized. From the methodology validation, we conclude that the quality of the obtained results is comparable with human-produced photointerpretations. We show that the accuracy associated with the measurement of mean trends from the automatically mapped patterns is less than 10 degrees . Through the analysis of two areas located near the MSL landing site in Gale Crater, we explore some of the possibilities that the automatic mapping technique enables. Namely, for multitemporal surveys and ripple pattern analysis. We demonstrate how the mapped ripple patterns can be used to assess local wind orientations, and we analyze some examples that illustrate the diversity of wavelength spatial distributions that can be found on Mars. We try to relate these pattern wavelength variations with the possible local influence of granulometry and wind shear velocity.

On Mars, major occurrences of spatially contiguous low-albedo sand dunes are primarily found in three major topographic settings: impact craters, high-latitude basins, and linear troughs or valleys, the largest being the Valles Marineris (VM) rift system. As one of the primary present day martian sediment sinks, VM holds nearly a third of the non-polar dune area on Mars. Moreover, VM differs from other regions due to its unusual geologic, topographic, and atmospheric setting. Herein, we test the overarching hypothesis that VM dune fields are compositionally, morphologically, and thermophysically distinct from other low- and mid-latitude (50 degrees N-50 degrees S latitude) dune fields. Topographic measurements of dune fields and their underlying terrains indicate slopes, roughnesses, and reliefs to be notably greater for those in VM. Variable VM dune morphologies are shown with topographically-related duneforms (climbing, falling, and echo dunes) located among spur-and-gully wall, landslide, and chaotic terrains, contrasting most martian dunes found in more topographically benign locations (e.g., craters, basins). VM dune fields superposed on Late Amazonian landslides are constrained to have formed and/or migrated over >10s of kilometers in the last 50 My to 1 Gy. Diversity of detected dune sand compositions, including unaltered ultramafic minerals and glasses (e.g., high and low-calcium pyroxene, olivine, Fe-bearing glass), and alteration products (hydrated sulfates, weathered Fe-bearing glass), is more pronounced in VM. Observations show heterogeneous sand compositions exist at the regional-, basinal-, dune field-, and dune-scales. Although not substantially greater than elsewhere, unambiguous evidence for recent dune activity in VM is indicated from pairs of high-resolution images that include: dune deflation, dune migration, slip face modification (e.g., alcoves), and ripple modification or migration, at varying scales (10s-100s m (super 2) ). We conclude that VM dune fields are qualitatively and quantitatively distinct from other low- and mid-latitude dune fields, most readily attributable to the rift's unusual setting. Moreover, results imply dune field properties and aeolian processes on Mars can be largely influenced by regional environment, which may have their own distinctive set of boundary conditions, rather than a globally homogenous collection of aeolian sediment and bedforms.

This model shows the value of exploring these highly directional and geometrical features in light of both their backscattering cross-section and emissivity. Compared to Cassini concurrent radar and radiometry data acquired from October 2004 to June 2011 over Titan's dune fields, it provides clues to understand variations among dune regions on the largest Saturn's moon. In particular, it brings a formal support to the idea first advanced in Le Gall et al. (Le Gall, A., Janssen, M.A., Wye, L.C., Hayes, A.G., Radebaugh, J., Savage, C., Zebker, H., Lorenz, R.D., Lunine, J.I., Kirk, R.L., Lopes, R.M.C., Wall, S., Callahan, P., Stofan, E.R., Farr, T. and the Cassini Radar Team [2011]. Icarus 213, 608-624) that the size of the interdune valleys (relative to that of the dunes) varies across Titan as well as the diffuse scattering properties of these interdune areas due to different thickness of sand cover (i.e. bedrock contribution) or degree of compaction/heterogeneity of the sand cover. The Fensal and Belet dune fields, in particular, are quite different in terms of these properties. The comparison between the model and Cassini data also reveals the potential presence of structures, possibly small-superposed dunes, oriented perpendicular to the dune crests in the Aztlan region.

Lacustrine, wetland and fluvial deposition took place between about 1.9 and 0.72 Ma at Munyu wa Gicheru in the northern part of the study area. Sedimentation continued about 40 km further south to produce the lake, wetland, fluvial and pedogenic deposits of the Olorgesailie Formation between about 1.2 and 0.5 Ma. Faulting subsequently led to basin breakup at Olorgesailie and the development of Middle to Late Pleistocene cut-and-fill fluvial deposits, as well as pond, wetland and terrestrial sediments that were locally altered by pedogenesis. Tufas and calcretes also accumulated during this latter time interval. Sedimentation in these different depositional sequences reflects several long-term trends, including: 1) an increase in carbonate deposition; 2) a decrease in biogenic silica; and 3) decreased chemical weathering indices (Chemical Index of Alteration, Vogt ratios), which imply increasing Quaternary aridity and/or erosion of catchment soils. The biophile elements Br and S also increase upwards, suggesting pulses of erosion of organic soils. Plants permineralized by silica became widespread after about 0.5 Ma, providing evidence that groundwater bodies were becoming silica-enriched, possibly as a result of deeper water circulation along active faults. Several fault-aligned fossil hot spring deposits with siliceous vent, pedogenic and swamp facies have been identified at Emerit in the central part of the Kedong-Olorgesailie rift. Tectonism also provided pathways for meteoric water that led to the formation of carbonate springs in the Olorgesailie area. REE patterns in clastic sediments are stable throughout the Quaternary, reflecting the dominant trachytic source rocks, but these patterns become variable in later Pleistocene calcretes and tufas documenting changing hydrochemical conditions. The geochemical evolution of the area partly reflects climate change through time. However, it also documents the influence of Quaternary rifting processes. Rift faulting affected the geochemistry of the basin sediments by 1) causing changes in the depth of fracture systems that controlled groundwater movements and sourcing of fluids, 2) changing accommodation space in which sediments could accumulate, and 3) altering relief and thus rainfall and evaporation patterns across the rift system, as well as erosion and weathering rates.

Uncertainties exist about tidal marsh resiliency to accelerated sea-level rise, reduced sediment supply, reduced plant productivity under increased inundation, and limited upland habitat for marsh migration. We examined marsh resiliency under these uncertainties using the Marsh Equilibrium Model, a mechanistic, elevation-based soil cohort model, using a rich data set of plant productivity and physical properties from sites across the estuarine salinity gradient. Four tidal marshes were chosen along this gradient: two islands and two with adjacent uplands. Varying century sea-level rise (52, 100, 165, 180 cm) and suspended sediment concentrations (100%, 50%, and 25% of current concentrations), we simulated marsh accretion across vegetated elevations for 100 years, applying the results to high spatial resolution digital elevation models to quantify potential changes in marsh distributions. At low rates of sea-level rise and mid-high sediment concentrations, all marshes maintained vegetated elevations indicative of mid/high marsh habitat. With century sea-level rise at 100 and 165 cm, marshes shifted to low marsh elevations; mid/high marsh elevations were found only in former uplands. At the highest century sea-level rise and lowest sediment concentrations, the island marshes became dominated by mudflat elevations. Under the same sediment concentrations, low salinity brackish marshes containing highly productive vegetation had slower elevation loss compared to more saline sites with lower productivity. A similar trend was documented when comparing against a marsh accretion model that did not model vegetation feedbacks. Elevation predictions using the Marsh Equilibrium Model highlight the importance of including vegetation responses to sea-level rise. These results also emphasize the importance of adjacent uplands for long-term marsh survival and incorporating such areas in conservation planning efforts.

Recent studies have reported shocked minerals in modern alluvium in a subtropical climate from the deeply eroded 2.02 Ga Vredefort Dome impact basin in South Africa. To evaluate the detrital shocked mineral record at a large impact structure in a temperate setting with a Holocene glacial erosional history, we investigated approximately 4000 detrital zircons and approximately 20,000 quartz grains at the less-eroded 1.85 Ga Sudbury Basin in Ontario, Canada, for the presence of shocked sand grains. Modern alluvium from rivers within and outside the basin, and Holocene glaciofluvial sands (eskers and outwash deltas) across the basin were investigated for shocked minerals. Shocked zircon and/or quartz were found in all modern rivers and most Holocene glacial deposits within, but not outside, the basin. Petrography and scanning electron microscopy (SEM; backscattered electron [BSE]; cathodoluminescence [CL]) imaging and analysis (energy-dispersive X-ray spectroscopy [EDS], electron backscatter diffraction [EBSD]) were used to document shock microstructures. Of the total detrital zircons surveyed, approximately 3% (118/3978) were identified as shocked; Holocene samples contained higher average percentages of shocked zircon (63/1361, or 4.6%, with a high of 29%) compared to modern alluvium (55/2617, or 2.1%, with a high of 6%). EBSD analysis revealed a range of shock microstructures, including planar fractures, deformation microtwins, and crystal plastic deformation. At Sudbury, detrital shocked quartz is rare compared to zircon; only 15 grains ( approximately 0.08%) were identified, all with decorated planar deformation features (PDFs).These results demonstrate that a detrital shocked mineral record exists at a large impact basin that is in a "youthful" stage of erosion, despite its age. In addition to modern alluvium, our results also identify glaciofluvial eskers and deltas as reservoirs for detrital shocked minerals; glacial episodes thus enhance the dispersal and preservation of shocked detritus in sedimentary systems. Despite physical differences, the observation that the two largest Precambrian impact basins continue to contribute detrital shocked minerals 2 b.y. after impact suggests that a shocked mineral record of impacts on early Earth should reside in Precambrian siliciclastic rocks.

There are 49 planet candidates around these stars, including 42 detected through transits and 7 revealed by precise Doppler measurements of the host stars. Based on an analysis of the Kepler brightness measurements, along with high-resolution imaging and spectroscopy, Doppler spectroscopy, and (for 11 stars) asteroseismology, we establish low false-positive probabilities (FPPs) for all of the transiting planets (41 of 42 have an FPP under 1%), and we constrain their sizes and masses. Most of the transiting planets are smaller than three times the size of Earth. For 16 planets, the Doppler signal was securely detected, providing a direct measurement of the planet's mass. For the other 26 planets we provide either marginal mass measurements or upper limits to their masses and densities; in many cases we can rule out a rocky composition. We identify six planets with densities above 5 g cm (super -3) , suggesting a mostly rocky interior for them. Indeed, the only planets that are compatible with a purely rocky composition are smaller than ~2 R (sub ⊕) . Larger planets evidently contain a larger fraction of low-density material (H, He, and H (sub 2) O). Copyright (Copyright) 2014. The American Astronomical Society. All rights reserved.

Although scarce, the remains are remarkable because of their geochronologic proximity to the main phase of Great American Biotic Interchange (GABI). The cladistic analysis conducted reveals that Pliodasypus groups with Dasypus and both are sister taxa of Propraopus, whereas Anadasypus is at a basal position. With respect to the records of tribe Dasypodini, after its oldest representative (Anadasypus, middle and late Miocene), the chronologically subsequent form is Pl. vergelianus (middle Pliocene), followed by Dasypus bellus in higher northern latitudes (late Pliocene), and then by widespread occurrences in the Pleistocene of North America (D. bellus) and South America (Propraopus, Dasypus punctatus, and Dasypus novemcinctus). Thus, we infer that Dasypus differentiated in the late Pliocene at low latitudes in the northern South America. It leads to two alternative hypotheses of dispersal: (a) some early Dasypus remained cryptically in South America until the Pleistocene, whereas others dispersed to North America between 2.2 and 2.7 Ma, or (b) they dispersed to North America subsequently to the emersion of the Panamanian isthmus and D. bellus differentiated there; later, during the Pleistocene, D. bellus entered South America and experienced speciation. The same process of re-ingression has been proposed to other xenarthrans, breaking with the traditional assumption that the GABI was unidirectional.

We assessed its phylogeographic structure in the 1st such study based on dense geographic sampling of any vertebrate from dry habitats in this region. We sequenced the cytochrome-b gene and the X-linked intron O-linked N-acetylglucosamine transferase, largely from dried skins and residual tissue on osteological material of museum specimens. Phylogenetic analyses revealed the existence of 2 well-supported phylogroups primarily distributed to the east and west of the Cordillera de Merida. The estimated time since divergence between these phylogroups postdates the Miocene; therefore, Andean uplifts, changes in the course of the Rio Orinoco, and marine transgressions of that epoch cannot be implicated as causal vicariant agents. Instead, expansion of humid forest or marine transgressions, or both, during the Pliocene and Pleistocene more likely led to this differentiation. We encountered little structure among populations east of the Cordillera de Merida, suggesting recent range expansion in this region. Surprisingly, isolated populations from the Peninsula de Paraguana (northwestern Venezuela) are not closely related to geographically proximate mainland populations, but rather to more distant populations to the west in Colombia and Panama. By contrast, populations from central and eastern Venezuela are closely related to those on the islands of Trinidad and Tobago. This genetic similarity among currently disjunct populations of M. robinsoni might have resulted from Holocene fragmentation of a more extensive Pleistocene distribution on coastal plains that were exposed during the last glacial maximum. Marmosa robinsoni tipicamente habita arbustales secos, sabanas, y bosques deciduos de Panama, Colombia, y Venezuela, y se encuentra presente tambien en las islas de Trinidad, Tobago, y Granada. En este estudio evaluamos la estructura filogeografica de M. robinsoni en lo que, hasta donde sabemos, representa el primer estudio de este tipo basado en un muestreo geografico denso de un vertebrado de los habitats secos del norte de Suramerica. Secuenciamos el gen mitocondrial citocromo b y el intron nuclear O-N-acetilglucosamina transferasa (ubicado en el cromosoma X). Para ello, obtuvimos ADN principalmente a partir de pieles de estudio y tejido residual tomado de material osteologico de ejemplares de museos. Los analisis filogeneticos revelaron (con buen apoyo) la existencia de dos filogrupos predominantemente distribuidos al Este y Oeste de la Cordillera de Merida. La estimacion del tiempo transcurrido desde que estos dos filogrupos divergieron claramente indica que tal divergencia ocurrio luego del Mioceno; por lo tanto, el levantamiento de los Andes, los cambios de curso del Rio Orinoco, y las transgresiones marinas de esa epoca no pueden ser consideradas como posibles agentes vicariantes relevantes entre estos grupos. En cambio, expansiones de bosques humedos y/o transgresiones marinas durante el Plioceno y Pleistoceno podrian haber causado esta divergencia. Encontramos poca estructura filogeografica entre las poblaciones al Este de la Cordillera de Merida, lo cual sugiere una expansion reciente a esta region. Sorprendentemente, poblaciones aisladas en la Peninsula de Paraguana (noroeste de Venezuela) no estan cercanamente relacionadas con las poblaciones geograficamente mas proximas (continentales y adyacentes a la peninsula), sino a las poblaciones mas distantes al Oeste en Colombia y Panama. En cambio, las poblaciones del centro y del oriente de Venezuela estan cercanamente relacionadas a poblaciones presentes en las islas Trinidad y Tobago. Esta similitud genetica entre poblaciones disyuntas podria haberse originado en el Holoceno, posiblemente por la fragmentacion de una distribucion mas amplia de M. robinsoni durante el fin del Pleistoceno, cuando la especie podria haber ocupado planicies costeras expuestas por el ultimo maximo glacial.

A major challenge has been the lack of an efficient, reliable and broadly applicable method for measuring the strength of migratory connections between populations across the annual cycle. Here, we show how high-resolution genetic markers can be used to identify genetically distinct groups of a migratory bird, the Wilson's warbler (Cardellina pusilla), at fine enough spatial scales to facilitate assessing regional drivers of demographic trends. By screening 1626 samples using 96 highly divergent single nucleotide polymorphisms selected from a large pool of candidates ( similar to 450 000), we identify novel region-specific migratory routes and timetables of migration along the Pacific Flyway. Our results illustrate that high-resolution genetic markers are more reliable, precise and amenable to high throughput screening than previously described intrinsic marking techniques, making them broadly applicable to large-scale monitoring and conservation of migratory organisms.

These backscatter differences are much less pronounced at 12.6 cm wavelength, consistent with a large component of the 70 cm echo arising from the rough or blocky transition zone between the mare regolith and the intact bedrock. Such deep probing is possible because the ilmenite content, which modulates microwave losses, of central Mare Serenitatis is generally low (2-3% by weight). Modeling of the radar returns from a buried interface shows that an average regolith thickness of 10 m could lead to the observed shifts in 70 cm echo power with a change in TiO (sub 2) content from 2% to 3%. This thickness is consistent with estimates of regolith depth (10-15 m) based on the smallest diameter for which fresh craters have obvious blocky ejecta. The 70 cm backscatter differences provide a view of mare flow-unit boundaries, channels, and lobes unseen by other remote sensing methods. A localized pyroclastic deposit associated with Rima Calippus is identified based on its low radar echo strength. Radar mapping also improves delineation of units for crater age dating and highlights a 250 km long, east-west trending feature in northern Mare Serenitatis that we suggest is a large graben flooded by late-stage mare flows.

They comprise the majority of asteroids in the Jupiter Trojan population, and are also commonly found in the outer main belt and among Hildas. The first evidence for D-types in the inner and middle parts of the main belt was seen in the Sloan Digital Sky Survey (SDSS). Here we report follow-up observations of SDSS D-type candidates in the near-infrared. Based on follow up observations of 13 SDSS D-type candidates, we find a approximately 20% positive confirmation rate. Known inner belt D-types range in diameter from roughly 7 to 30 km. Based on these detections we estimate there are approximately 100 inner belt D-types with diameters between 2.5 and 20 km. The lower and upper limits for total mass of inner belt D-types is 2 X 10 (super 16) kg to 2 X 10 (super 17) kg which represents 0.01-0.1% of the mass of the inner belt. The inner belt D-types have albedos at or above the upper end typical for D-types which raises the question as to whether these inner belt bodies represent only a subset of D-types, they have been altered by external factors such as weathering processes, or if they are compositionally distinct from other D-types. All D-types and candidates have diameters less than 30 km, yet there is no obvious parent body in the inner belt. Dynamical models have yet to show how D-types originating from the outer Solar System could penetrate into the inner reaches of the main belt under current scenarios of planet formation and subsequent Yarkovsky drift.

During deposition of at least the uppermost 100 m of fan deposits, discharges from the source basin consisted of channelized flows transporting sediment (which we infer to be primarily sand- and gravel-sized) as bedload coupled with extensive overbank mud-rich flows depositing planar beds of sand-sized or finer sediment. Flow events are inferred to have been of modest magnitude (probably less than approximately 60 m (super 3) /s), of short duration, and probably occupied only a few distributaries during any individual flow event. Occasional channel avulsions resulted in the distribution of sediment across the entire fan. A comparison with fine-grained alluvial fans in Chile's Atacama Desert provides insights into the processes responsible for constructing the Saheki crater fans: sediment is deposited by channelized flows (transporting sand through boulder-sized material) and overbank mudflows (sand size and finer) and wind erosion leaves channels expressed in inverted topographic relief. The most likely source of water was snowmelt released after annual or epochal accumulation of snow in the headwater source basin on the interior crater rim during the Hesperian to Amazonian periods. We infer the Saheki fans to have been constructed by many hundreds of separate flow events, and accumulation of the necessary snow and release of meltwater may have required favorable orbital configurations or transient global warming.

Integral projection models (IPMs) use information on how an individual's state influences its vital rates - survival, growth and reproduction - to make population projections. IPMs are constructed from regression models predicting vital rates from state variables (e.g. size or age) and covariates (e.g. environment). By combining regressions of vital rates, an IPM provides mechanistic insight into emergent ecological patterns such as population dynamics, species geographic distributions or life-history strategies. 2. Here, we review important resources for building IPMs and provide a comprehensive guide, with extensive R code, for their construction. IPMs can be applied to any stage-structured population; here, we illustrate IPMs for a series of plant life histories of increasing complexity and biological realism, highlighting the utility of various regression methods for capturing biological patterns. We also present case studies illustrating how IPMs can be used to predict species' geographic distributions and life-history strategies. 3. IPMs can represent a wide range of life histories at any desired level of biological detail. Much of the strength of IPMs lies in the strength of regression models. Many subtleties arise when scaling from vital rate regressions to population-level patterns, so we provide a set of diagnostics and guidelines to ensure that models are biologically plausible. Moreover, IPMs can exploit a large existing suite of analytical tools developed for matrix projection models.

Abundance, reproductive biology (fecundity, reproductive output and egg size) and population structure (frequency distribution, size at sex phase change and sex phase ratio) were examined at three different fishing grounds off south and west-central Florida between May 2011 and February 2012. Fishery-dependent densities of L. boggessi varied between 2.51 plus or minus 1.39 and 13.05 plus or minus 9.30 shrimps per 1000 m super(2) at two different localities. The proportion of brooding shrimp varied considerably at one locality during two different dates, suggesting reproductive seasonality. Reproductive output increased linearly with shrimp body weight (SBW) at one locality (May 2011), but scaled negatively with SBW at a second locality (January-February 2012). Lastly, no correlation between embryo size and shrimp carapace length (CL) was recorded at one locality (May 2011), but a slight negative correlation between embryo size and CL was found at the second locality (January-February 2012). Lysmata boggessi might be experiencing trade-offs between different reproductive parameters driven by environmental, probably seasonal, conditions during the year. All of this information needs to be considered in assessing shrimp stocks and establishing a sustainable management plan.
