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. Whatever the cause, the main building phase of Mercury's crust ended within the first 20% of the age of the planet, with only small-scale, explosive volcanism enduring beyond that time.

Insights from observations of crystallization kinetics in experiments on Glass Mountain obsidians (Long Valley, CA) AN - 1849298573; 2016-105995 AB - The Glass Mountain obsidians (Long Valley, CA) are crystal-poor (<8%) and highly-evolved (high SiO2, low MgO, Sr, Ba) and, therefore, their formation required extremely efficient crystal-liquid separation. 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 (
