TY - JOUR T1 - STELLAR GRANULATION AS THE SOURCE OF HIGH-FREQUENCY FLICKER IN KEPLER LIGHT CURVES AN - 1705081181; PQ0001812186 AB - A large fraction of cool, low-mass stars exhibit brightness fluctuations that arise from a combination of convective granulation, acoustic oscillations, magnetic activity, and stellar rotation. Much of the short-timescale variability takes the form of stochastic noise, whose presence may limit the progress of extrasolar planet detection and characterization. In order to lay the groundwork for extracting useful information from these quasi-random signals, we focus on the origin of the granulation-driven component of the variability. We apply existing theoretical scaling relations to predict the star-integrated variability amplitudes for 508 stars with photometric light curves measured by the Kepler mission. We also derive an empirical correction factor that aims to account for the suppression of convection in F-dwarf stars with magnetic activity and shallow convection zones. So that we can make predictions of specific observational quantities, we performed Monte Carlo simulations of granulation light curves using a Lorentzian power spectrum. These simulations allowed us to reproduce the so-called flicker floor (i.e., a lower bound in the relationship between the full light-curve range and power in short-timescale fluctuations) that was found in the Kepler data. The Monte Carlo model also enabled us to convert the modeled fluctuation variance into a flicker amplitude directly comparable with observations. When the magnetic suppression factor described above is applied, the model reproduces the observed correlation between stellar surface gravity and flicker amplitude. Observationally validated models like these provide new and complementary evidence for a possible impact of magnetic activity on the properties of near-surface convection.

The high-quality broadband spectrum enables us to separate the effects of distant reflection from the direct coronal continuum, and to therefore accurately measure the high-energy cutoff to be E sub(cut) = 178 super(+74) sub(-40) keV. The coronal emission arises from accretion disk photons Compton up-scattered by a thermal plasma, with the spectral index and cutoff being due to a combination of the finite plasma temperature and optical depth. Applying standard Comptonization models, we measure both physical properties independently using the best signal to noise obtained to date in an active galactic nucleus over the 3-79 keV band. We derive kT sub(e) = 37 super(+7) sub(-6)keV with [tau] = 1.25 super(+0.20) sub(-0.10) assuming a slab geometry for the plasma, and kT sub(e) = 33 super(+6) sub(-6) keV with [tau] = 3.41 super(+0.58) sub(-0.38) for a spherical geometry, with both having an equivalent goodness-of-fit.

We present a framework for identifying subpopulations in mega-patches using a combination of spatial autocorrelation and graph theory analyses. We find that the relationships between patch characteristics such as area and connectivity and the demographic processes of colonizations and extinctions vary among the different patch-definition methods. Our spatial-analysis/graph-theoretic framework produces results that match theoretical expectations better than the other methods. This approach can be used to identify subpopulations in metapopulations where the distributions of organisms do not always reflect the distribution of suitable habitat. This paper talks about the patch definition in metapopulation analysis, a graph theory approach to solve the mega-patch problem.

Orbiting the Sun between Mars and Jupiter, they are thought to be the shattered remnants of small bodies formed within the young Sun's solar nebula that never accreted enough material to become planets. These "minor bodies" are therefore keys to understanding how the Solar System formed and evolved. As leftover planetary building blocks, they are of great importance in understanding planetary compositions. They may also provide clues to the origin of life, as similar bodies may have delivered organics and water to the early Earth. For these reasons, several international space agencies have funded sample-return missions to asteroids.

In the Gamba Complex of Protected Areas in Gabon, which includes 2 national parks separated by a MUA containing energy and forestry concessions, we studied forest elephants to evaluate the importance of the MUA to wide-ranging species. We extracted DNA from elephant dung samples and used genetic information to identify over 500 individuals in the MUA and the parks. We then examined patterns of nuclear microsatellites and mitochondrial control-region sequences to infer population structure, movement patterns, and habitat use by age and sex. Population structure was weak but significant, and differentiation was more pronounced during the wet season. Within the MUA, males were more strongly associated with open habitats, such as wetlands and savannas, than females during the dry season. Many of the movements detected within and between seasons involved the wetlands and bordering lagoons. Our results suggest that the MUA provides year-round habitat for some elephants and additional habitat for others whose primary range is in the parks. With the continuing loss of roadless wilderness areas in Central Africa, well-managed MUAs will likely be important to the conservation of wide-ranging species.Original Abstract: Utilizacion de Perfiles Geneticos de Elefantes Africanos para Inferir su Estructura Poblacional, Movimientos y Uso del Habitat en un Paisaje con Conservacion y Desarrollo en Gabon Resumenfgs La conservacion de especies con distribucion amplia, como el elefante africano (Loxodonta cyclotis), depende de areas completamente protegidas y de areas de uso multiple (AUM) que proporcionan conectividad de habitat. En el Complejo Gamba de Areas Protegidas en Gabon, que incluye 2 parques nacionales separados por un area de uso multiple que contiene concesiones de energeticas y forestales, estudiamos a los elefantes para evaluar la importancia de las AUM para especies con distribucion amplia. Extrajimos ADN de muestras de excretas de elefante y utilizamos la informacion genetica para identificar mas de 500 individuos en el AUM y los parques. Posteriormente examinamos los patrones en las secuencias de los microsatelites nucleares y de la region de control mitocondrial para inferir la estructura poblacional, los patrones de movimiento y el uso de habitat por edad y sexo. La estructura poblacional fue debil pero significativa, y la diferenciacion fue mas pronunciada durante la epoca de lluvias. En el AUM, los machos estan mas fuertemente asociados con los habitats abiertos, como humedales y sabanas, que las hembras durante el estiaje. Muchos de los movimientos detectados dentro y entre estaciones involucro a los humedales y lagunas circundantes. Nuestros resultados sugieren que el AUM proporciona habitat todo el ano para algunos elefantes y habitat adicional para otros cuya distribucion primaria esta en los parques. Con la perdida continua de areas silvestres en Africa Central, es probable que AUM manejadas adecuadamente sean importantes para la conservacion de especies con distribucion amplia.

These invasions transformed land ecosystems in South and Middle America. Humans invading from Asia over 12000 years ago killed most mammals over 44 kg, again transforming tropical American ecosystems. As a sea barrier, the isthmus induced divergent environmental change off its two coasts-creating contrasting ecosystems through differential extinction and diversification. Approximately 65 Ma invading marsupials and ungulates of North American ancestry, and xenarthrans of uncertain provenance replaced nearly all South America's non-volant mammals. There is no geological evidence for a land bridge at that time. Together with rodents and primates crossing from Africa 42 to 30 Ma, South America's mammals evolved in isolation until the interchange's first heralds less than 10 Ma. Its carnivores were ineffective marsupials. Meanwhile, North America was invaded by more competitive Eurasian mammals. The Americas had comparable expanses of tropical forest 55 Ma; later, climate change confined North American tropical forest to a far smaller area. When the isthmus formed, North American carnivores replaced their marsupial counterparts. Although invaders crossed in both directions, North American mammals spread widely, diversified greatly, and steadily replaced South American open-country counterparts, unused to effective predators. Invading South American mammals were less successful. South America's birds, bats, and smaller rainforest mammals, equally isolated, mostly survived invasion. Its vegetation, enriched by many overseas invaders, remained intact. This vegetation resists herbivory effectively. When climate permitted, South America's rainforest, with its bats, birds and mammals, spread to Mexico. Present-day tropical American vegetation is largely zoned by trade-offs between exploiting well-watered settings versus surviving droughts, exploiting fertile versus coping with poor soil, and exploiting lowland warmth versus coping with cooler altitudes. At the start of the Miocene, a common marine biota extended from Trinidad to Ecuador and western Mexico, which evolved in isolation from the Indo-Pacific until the Pleistocene. The seaway between the Americas began shoaling over 12 Ma. About 10 Ma the land bridge was briefly near-complete, allowing some interchange of land mammals between the continents. By 7 Ma, the rising sill had split deeper-water populations. Sea temperature, salinity and sedimentary carbon content had begun to increase in the Southern Caribbean, but not the Pacific. By 4 Ma, the seaway's narrowing began to extinguish Caribbean upwellings. By 2 Ma, upwellings remained only along Venezuela; Caribbean plankton, suspension-feeding molluscs and their predators had declined sharply, largely replaced by bottom-dwelling corals and calcareous algae and magnificent coral reefs. Closing the seaway extinguished the Eastern Pacific's reef corals (successors recolonized from the Indo-Pacific 6000 years ago), whereas many molluscs of productive waters that once thrived in the Caribbean now survive only in the Eastern Pacific. The present-day productive Eastern Pacific, with few, small coral reefs and a plankton-based ecosystem contrasts with the Caribbean, whose clear water favours expansive coral reefs and bottom-dwelling primary producers. These ecosystems reflect the trade-off between fast growth and effective defence with attendant longevity. Overfishing with new technologies during the last few centuries, however, has caused population crashes of ever-smaller marine animals, devastating Caribbean ecosystems.

This aqueous environment was characterized by neutral pH, low salinity, and variable redox states of both iron and sulfur species. Carbon, hydrogen, oxygen, sulfur, nitrogen, and phosphorus were measured directly as key biogenic elements; by inference, phosphorus is assumed to have been available. The environment probably had a minimum duration of hundreds to tens of thousands of years. These results highlight the biological viability of fluvial-lacustrine environments in the post-Noachian history of Mars.

A K-Ar age of 4.21 + or - 0.35 billion years represents a mixture of detrital and authigenic components and confirms the expected antiquity of rocks comprising the crater rim. Cosmic-ray-produced (super 3) He, (super 21) Ne, and (super 36) Ar yield concordant surface exposure ages of 78 + or - 30 million years. Surface exposure occurred mainly in the present geomorphic setting rather than during primary erosion and transport. Our observations are consistent with mudstone deposition shortly after the Gale impact or possibly in a later event of rapid erosion and deposition. The mudstone remained buried until recent exposure by wind-driven scarp retreat. Sedimentary rocks exposed by this mechanism may thus offer the best potential for organic biomarker preservation against destruction by cosmic radiation.

H (sub 2) O/OH-bearing phases included 2:1 phyllosilicate(s), bassanite, akaganeite, and amorphous materials. Thermal decomposition of carbonates and combustion of organic materials are candidate sources for the CO (sub 2) . Concurrent evolution of O (sub 2) and chlorinated hydrocarbons suggests the presence of oxychlorine phase(s). Sulfides are likely sources for sulfur-bearing species. Higher abundances of chlorinated hydrocarbons in the mudstone compared with Rocknest windblown materials previously analyzed by Curiosity suggest that indigenous martian or meteoritic organic carbon sources may be preserved in the mudstone; however, the carbon source for the chlorinated hydrocarbons is not definitively of martian origin.

No evidence of chemical weathering is preserved, indicating arid, possibly cold, paleoclimates and rapid erosion and deposition. The absence of predicted geochemical variations indicates that magnetite and phyllosilicates formed by diagenesis under low-temperature, circumneutral pH, rock-dominated aqueous conditions. Analyses of diagenetic features (including concretions, raised ridges, and fractures) at high spatial resolution indicate that they are composed of iron- and halogen-rich components, magnesium-iron-chlorine-rich components, and hydrated calcium sulfates, respectively.

The geochemistry of these sedimentary rocks provides further evidence for diverse depositional and diagenetic sedimentary environments during the early history of Mars.

One of the most promising NEO candidates for a cometary origin is near-Earth asteroid (3552) Don Quixote, which has never been reported to show activity. Here we present the discovery of cometary activity in Don Quixote based on thermal-infrared observations made with the Spitzer Space Telescope in its 3.6 and 4.5 mu m bands. Our observations clearly show the presence of a coma and a tail in the 4.5 mu m but not in the 3.6 mu m band, which is consistent with molecular band emission from CO (sub 2) . Thermal modeling of the combined photometric data on Don Quixote reveals a diameter of 18.4 (sub -0.4) (super 0.3) km and an albedo of 0.03 (sub -0.01) (super 0.02) , which confirms Don Quixote to be the third-largest known NEO. We derive an upper limit on the dust production rate of 1.9 kg s (super -1) and derive a CO (sub 2) gas production rate of (1.1 + or - 0.1) X 10 (super 26) molecules s (super -1) . Spitzer Infrared Spectrograph spectroscopic observations indicate the presence of fine-grained silicates, perhaps pyroxene rich, on the surface of Don Quixote. Our discovery suggests that CO (sub 2) can be present in near-Earth space over a long time. The presence of CO (sub 2) might also explain that Don Quixote's cometary nature remained hidden for nearly three decades. Copyright (Copyright) 2014. The American Astronomical Society.

We explore such detectability with each of the three upcoming Extremely Large Telescopes (ELTs), i.e., GMT, TMT, and E-ELT, and high resolution spectrographs, assuming such instruments will be available in all ELTs. With these simulations we extend previous studies by taking into account atmospheric refraction in the transmission spectrum of the exo-Earth and observational white and red noise contributions. Our studies reveal that the number of transits necessary to detect O sub(2) in the atmosphere of an Earth twin around an M dwarf is by far higher than the number of transits estimated by Snellen et al. In addition, our simulations show that, when accounting for typical noise levels associated with observations in the optical and near-infrared, the O sub(2) A band at 760 nm is more favorable for detecting the exoplanetary signal than the O sub(2) band at 1268 nm for all the spectral types, except M9V. We conclude that, unless unpredicted instrumental limitations arise, the implementation of pre-slit optics such as image slicers appears to be key to significantly improving the yield of this particular science case. However, even in the most optimistic cases, we conclude that the detection of O sub(2) in the atmosphere of an Earth twin will only be feasible with the ELTs if the planet is orbiting a bright close by (d [< or =, slant] 8 pc) M dwarf with a spectral type later than M3.

The combination of spectroscopy with albedos and diameters derived from thermal infrared observations can increase the scientific return beyond that of the individual datasets. For instance, some taxonomic classes can be separated into distinct compositional groupings with albedo and different mineralogies with similar albedos can be distinguished with spectroscopy. To that end, we have completed a spectroscopic observing campaign to complement the ExploreNEOs Warm Spitzer program that obtained albedos and diameters of nearly 600 NEOs (Trilling, D.E. et al. [2010]. Astron. J. 140, 770-784. http://dx.doi.org/10.1088/0004-6256/140/3/770). The spectroscopy campaign included visible and near-infrared observations of ExploreNEOs targets from various observatories. Here we present the results of observations using the low-resolution prism mode ( approximately 0.7-2.5 mu m) of the SpeX instrument on the NASA Infrared Telescope Facility (IRTF). We also include near-infrared observations of ExploreNEOs targets from the MIT-UH-IRTF Joint Campaign for Spectral Reconnaissance. Our dataset includes near-infrared spectra of 187 ExploreNEOs targets (125 observations of 92 objects from our survey and 213 observations of 154 objects from the MIT survey). We identify a taxonomic class for each spectrum and use band parameter analysis to investigate the mineralogies for the S-, Q-, and V-complex objects. Our analysis suggests that for spectra that contain near-infrared data but lack the visible wavelength region, the Bus-DeMeo system misidentifies some S-types as Q-types. We find no correlation between spectral band parameters and ExploreNEOs albedos and diameters. We investigate the correlations of phase angle with Band Area Ratio and near-infrared spectral slope. We find slightly negative Band Area Ratio (BAR) correlations with phase angle for Eros and Ivar, but a positive BAR correlation with phase angle for Ganymed. The results of our phase angle study are consistent with those of (Sanchez, J.A., Reddy, V., Nathues, A., Cloutis, E.A., Mann, P., Hiesinger, H. [2012]. Icarus 220, 36-50. http://dx.doi.org/10.1016/j.icarus.2012.04.008, arXiv:1205.0248). We find evidence for spectral phase reddening for Eros, Ganymed, and Ivar. We identify the likely ordinary chondrite type analog for an appropriate subset of our sample. Our resulting proportions of H, L, and LL ordinary chondrites differ from those calculated for meteorite falls and in previous studies of ordinary chondrite-like NEOs.

The maximum Na/Si abundance ratio of 0.20 + or - 0.03 by weight ( approximately 5 wt% Na) is observed at high northern latitudes and is significantly larger than the equatorial Na/Si ratio of 0.11 + or - 0.01 ( approximately 2.6 wt% Na). Comparisons of forward-modeled surface distributions with the gamma-ray measurements suggest that the observed distribution of Na can be explained by differences in elemental composition between the volcanic smooth plains units and heavily cratered terrain. The comparison improves when thermally driven depletion of Na from areas near Mercury's hot poles is included. When combined with other MESSENGER data sets, these results indicate that the smooth plains units include substantial abundances of alkali feldspars. Thermal depletion of Na from the hot poles without an assumed underlying compositional variability can also reproduce the measured Na/Si distribution, but that mechanism fails to account for other MESSENGER observations that support the presence of higher abundances of feldspars in the smooth plains units.

However, no current U.S. estimates are based on systematic analysis of multiple data sources. We reviewed the published literature and acquired unpublished datasets to systematically quantify bird-building collision mortality and species-specific vulnerability. Based on 23 studies, we estimate that between 365 and 988 million birds (median = 599 million) are killed annually by building collisions in the U.S., with roughly 56% of mortality at low-rises, 44% at residences, and 92,000 fatality records, and after controlling for population abundance and range overlap with study sites, we identified several species that are disproportionately vulnerable to collisions at all building types. In addition, several species listed as national Birds of Conservation Concern due to their declining populations were identified to be highly vulnerable to building collisions, including Golden-winged Warbler (Vermivora chrysoptera), Painted Bunting (Passerina ciris), Canada Warbler (Cardellina canadensis), Wood Thrush (Hylocichla mustelina), Kentucky Warbler (Geothlypis formosa), and Worm-eating Warbler (Helmitheros vermivorum). The identification of these five migratory species with geographic ranges limited to eastern and central North America reflects seasonal and regional biases in the currently available building-collision data. Most sampling has occurred during migration and in the eastern U.S. Further research across seasons and in underrepresented regions is needed to reduce this bias. Nonetheless, we provide quantitative evidence to support the conclusion that building collisions are second only to feral and free-ranging pet cats, which are estimated to kill roughly four times as many birds each year, as the largest source of direct human-caused mortality for U.S. birds.

Biotic agents disperse most of these disseminules, whereas wind dispersal is less common. Although wind-dispersed fruits and seeds are greatly overshadowed in closed rainforests, many important families in the Neotropics (e.g., Bignoniaceae, Fabaceae, Malvaceae, Orchidaceae, Sapindaceae) show numerous morphological adaptations for anemochory (i.e. wings, accessory hairs). Most of these living groups have high to moderate levels of plant diversity in the upper levels of the canopy. Little is known about the fossil record of wind-dispersed fruits and seeds in the Neotropics. Six new species of disseminules with varied adaptations for wind dispersal are documented here. These fossils, representing extinct genera of Ulmaceae, Malvaceae, and some uncertain families, indicate that wind-dispersed fruit and seed syndromes were already common in the Neotropics by the Paleocene, coinciding with the early development of multistratal rainforests. Although the major families known to include most of the wind-dispersed disseminules in extant rainforests are still missing from the Paleogene fossil record of South and Central America, the new fossils imply that anemochory was a relatively important product and/or mechanism of plant evolution and diversification in early Neotropical rainforests.

Our work in the Mediterranean Sea, Gulf of California, Caribbean Sea, and elsewhere has shown how modern assemblages are responding to acidification. Around Ischia (Italy) natural seafloor CO2 vents are creating a low pH environment in which it is possible to observe the response of benthic foraminifera. At a pH of 7.8, the assemblage is already becoming less diverse and below pH 7.6 there are no calcite-secreting benthic foraminifera. In the Gulf of California, in a deeper-water setting, natural CO2 (and methane) vents are, again, lowering seafloor pH. The foraminifera show the impact of this change, although the relatively high carbonate saturation ensures that calcite-secreting foraminifera are able to live and reproduce in relatively low pH environments, only becoming impacted by dissolution effects once dead. Using data from a number of global bioevents (Triassic/Jurassic boundary, Cretaceous/Paleogene boundary and the Paleocene/Eocene boundary) it is now possible to determine the contribution of acidification to global bioevents, both in the near-surface and in deeper-water environments caused by the migration of the carbonate compensation depth (CCD). In Texas and Alabama, the Cretaceous/Paleogene boundary successions record no direct evidence of ocean acidification despite the proximity to the Chicxulub impact site and the proposed source of some of the CO2 (in addition to that from the Deccan Volcanic Center in India) required to cause the acidification. Interpretation of changes in the biota during global bioevents is complicated by the changing nature of the oceans through time, which have switched from being aragonitic to calcitic a number of times during the Phanerozoic. The other significant change is that from a "Neritan Ocean" to a "Cretan Ocean" in the mid-Jurassic.

How best to interpret this record has been controversial, but empirical and methodological advances have resolved at least two issues about pattern: (a) directional transformations are seldom sustained over geological timescales, and (b) net rates of morphological change in fossil species are usually quite slow. Considerable uncertainty remains, however, about the processes responsible for these patterns, but most fruitful explanations use the framework of adaptive landscapes to consider the role of natural selection and other processes. An additional, unresolved issue is the claim that most phenotypic change is associated with speciation. A variety of methods, using data from both fossil and extant species, have supported such a link, at least in some clades and traits, but its prevalence and underlying mechanism remain unresolved.

A large ensemble of coagulation calculations demonstrates a new formation channel: disks composed of large planetesimals with radii of 30-300 km form super-Earths on timescales of approximately 1 Gyr. In other gas-poor disks, a collisional cascade grinds planetesimals to dust before the largest planets reach super-Earth masses. Once icy Earth-mass planets form, they migrate through the leftover swarm of planetesimals at rates of 0.01-1 AU Myr (super -1) . On timescales of 10 Myr to 1 Gyr, many of these planets migrate through the disk of leftover planetesimals from semimajor axes of 5-10 AU to 1-2 AU. A few percent of super-Earths might migrate to semimajor axes of 0.1-0.2 AU. When the disk has an initial mass comparable with the minimum-mass solar nebula, scaled to the mass of the central star, the predicted frequency of super-Earths matches the observed frequency.

Many presolar Al (sub 2) O (sub 3) grains, which are the survival circumstellar dust grains, have been identified from acid-residues of chondrites. The grain morphology and crystal structure of presolar grains may reflect condensation conditions in circumstellar envelopes of AGB stars and processing in the interstellar medium (ISM) and protosolar disk. Using scanning electron microscopy (SEM) we obtained detailed secondary electron images, energy dispersive X-ray spectroscopy (EDS), electron backscattered diffraction (EBSD) patterns, and cathodoluminescence (CL) spectra of each Al (sub 2) O (sub 3) grain prior to isotopic measurements. Focused ion beam (FIB) lift-out sections were made from the identified presolar grains and the interior structures were observed with a transmission electron microscope (TEM). The Al (sub 2) O (sub 3) grains were identified from acid residues of QUE97008 (LL3.05) by EDS and observed in detail by field emission (FE) SEM at the Carnegie Institution of Washington (CIW). Previously identified alumina grains from Semarkona (LL3.0), Roosevelt County 075 (H3.1), and Bishunpur (LL3.15) were also used in this study. CL spectra were obtained with a FE-SEM equipped with a Gatan Mono CL4 system at NIST. EBSD analysis was performed with an FEI Nova 600 FIB-SEM equipped with an HKL EBSD system at the Naval Research Laboratory (NRL). Isotope measurements were performed with the Cameca NanoSIMS 50L ion-microprobe at CIW. Oxygen isotopes of 163 grains were measured using approximately 100 nm Cs+ beam rastered over each of the grains. An O- beam was used to measure the Mg-Al isotopic compositions of the presolar and some solar Al (sub 2) O (sub 3) grains. Ultra-thin sections of presolar grains QUE053, 060, and 067 were prepared with the NRL FIB-SEM. TEM studies were carried out at NRL with a JEOL 2200FS field-emission scanning transmission electron microscope (STEM). Eight presolar grains from QUE97008 and one from RC 075 were newly found. Grain QUE060 is classified into Group 2 and has a subhedral shape with clear flat facets. The surface is smooth except for a face with a cavity. TEM diffraction patterns of the FIB section indicated that the grain consists of multiple corundum crystallites. Dark-field TEM image showed large (>100 nm) and small (<30 nm) scale orientation variation. The large-scale misorientation observed on the right side of the grain seems to relate to the cavity. Small-scale distortions occur uniformly within the grain. EDS spectra showed that the Mg/Al ratio of QUE060 is approximately 0.01, and the NanoSIMS measurement revealed this high Mg content to be essentially pure radiogenic (super 26) Mg, with inferred initial (super 26) Al/ (super 27) Al approximately 0.01, similar to other Group 2 grains. QUE067 is a thin Group 4 grain with very irregular morphology. Its (super 27) Al/ (super 24) Mg ratio was three times lower than in QUE060, but its inferred (super 26) Al/ (super 27) Al ratio was similar. No EBSD patterns of crystals were obtained from the grain surface but TEM observation on the FIB section showed that the interior of QUE067 was corundum, not amorphous. The subhedral shape and smooth surface of QUE060 suggest that this grain was likely single crystalline corundum when it condensed in a circumstellar envelope of a low-mass AGB star, and that the polycrystalline nature, voids and distorted crystal structure inside the grain are secondary features. A possible process to form large-scale misorientation and the cavity is grain-grain collisions in a SN shock in the ISM. A high velocity collision creates a shockwave propagating inside the grain, finally forming a crater. Small-scaled distortions may have also formed by collisions with small particles in the ISM.

One experiment was conducted in an open, outdoor seawater system with H. opuntia, while the other was conducted in an indoor, closed system with H. incrassata and H. simulans. Feedings assays with common sea urchins (Lytechinus variegatus and Diadema antillarum) were further conducted to test the degree to which shifts in algal chemistry influence herbivore feeding preferences. Our results were variable among Halimeda spp., highlighting that OA-induced shifts in chemical composition are species-specific. OA reduced the CaCO sub(3) content (% dry wt) of H. incrassata yet had no effect on H. opuntia or H. simulans. Terpenoid metabolite concentrations were unaltered by pCO sub(2) for all species. Assays with sea urchins revealed that feeding significantly increased on diets of lower CaCO sub(3) and secondary metabolite content.

Our images made at 34, 46, and 62 MHz reach noise levels of 12, 8, and 5 mJy beam super(-1), making them the deepest images ever obtained in this frequency range. In total, we detect between 300 and 400 sources in each of these images, covering an area of 17-52 deg super(2). From the observations, we derive Euclidean-normalized differential source counts. The 62 MHz source counts agree with previous GMRT 153 MHz and Very Large Array 74 MHz differential source counts, scaling with a spectral index of -0.7. We find that a spectral index scaling of -0.5 is required to match up the LOFAR 34 MHz source counts. This result is also in agreement with source counts from the 38 MHz 8C survey, indicating that the average spectral index of radio sources flattens toward lower frequencies. We also find evidence for spectral flattening using the individual flux measurements of sources between 34 and 1400 MHz and by calculating the spectral index averaged over the source population. To select ultra-steep spectrum ( alpha < -1.1) radio sources that could be associated with massive high-redshift radio galaxies, we compute spectral indices between 62 MHz, 153 MHz, and 1.4 GHz for sources in the Bootes field. We cross-correlate these radio sources with optical and infrared catalogs and fit the spectral energy distribution to obtain photometric redshifts. We find that most of these ultra-steep spectrum sources are located in the 0.7 [<, ~] z [<, ~] 2.5 range.

The >23 hr continuous light curve was obtained with the Infrared Array Camera (IRAC) instrument in 2013 December. The result characterizes the variability of Sgr A* prior to the closest approach of the tidally deformed G2 object, a putative infalling gas cloud that orbits close to Sgr A*. The high stellar density at the location of Sgr A* produces a background of ~250 mJy at 4.5 mu m in each pixel with a large pixel-to-pixel gradient, but the light curve for the highly variable Sgr A* source was successfully measured by modeling and removing the variations due to pointing wobble. The observed flux densities range from the noise level of ~0.7 mJy rms in a 6.4 s measurement to [> ~]10 mJy. Emission was seen above the noise level ~34% of the time. The light-curve characteristics, including the flux density distribution and structure function, are consistent with those previously derived at shorter infrared wavelengths. We see no evidence in the light curve for activity attributable to the G2 interaction at the observing epoch, ~100 days before the expected G2 periapsis passage. The IRAC light curve is more than a factor of two longer than any previous infrared observation, improving constraints on the timescale of the break in the power spectral distribution of Sgr A* flux densities. The data favor the longer of the two previously published values for the timescale.

This interval has been associated with plant extinctions and a subsequent increase in plant diversity mostly in temperate latitudes. Nevertheless, documented fossil floras from this interval in the Neotropics are sparse. Here, we present preliminary results from a new fossil flora from the Late Eocene-Early Oligocene Esmeraldas Formation. The Flora is composed by well-preserved compressions and impressions of leaves, including abundant cuticles, also seeds, fruits and flowers. The Esmeraldas Formation presents deposits of fluvial and estuarine environments with tidal influence. The analysis of leaf architecture characters of fossil leaves from the Esmeraldas Flora indicates lower temperatures, when compared to Paleocene Floras from Colombia with similar environmental deposition, in addition to remarkable taxonomic differences. This Flora represents a unique opportunity to elucidate the consequences of climate change in the Neotropical Flora.

A stable isotope aridity index can be used to estimate water deficit (WD) using stable oxygen isotopes in mammalian tooth enamel. WD is a function of potential evapotranspiration (PET) and mean annual rainfall, and PET is a function of temperature and latitude. The index is based on a comparison of species that are categorized as evaporation insensitive (EI) and evaporation sensitive (ES), based on regressions between WD and the isotopic enrichment between oxygen isotope values in tooth enamel and local meteoric water (epsilon (sub enamel-mw) ). Taxa for which epsilon (sub enamel-mw) does not change with WD are classified as EI, and reflect local meteoric water. Taxa for which epsilon (sub enamel-mw) is sensitive to aridity are classified as ES, and reflect evaporative water sources (i.e. leaf or body water). Isotopic enrichment between EI and ES taxa increases with aridity. We present a revised calibration for the aridity index, based on a large compilation of previously published and new oxygen isotope values in tooth enamel (n > 1100 from 53 species of large mammals representing 34 locations in eastern and central Africa), that includes updated PET estimates and represents a substantially expanded range of WD values (>3700 mm/year). The aridity index is used to estimate water deficit in the early Pleistocene of the Lake Victoria Basin, western Kenya. We present oxygen isotope values in fossil mammalian tooth enamel from the Homa Peninsula localities Kanjera South (ca. 2.0 Ma) and Nyayanga (1.78-2.3 Ma). We find that paleo-aridity estimates fall within the range of WD values in modern eastern African savanna biomes, and indicate that Kanjera South was less arid than Nyayanga. While paleo-aridity estimates must be interpreted with caution due to challenges relating to sample size, classification of EI and ES taxa, and geological context, these results demonstrate that this index can be used to reconstruct terrestrial paleoclimatic variation relevant to hominin evolution. Characterizing extant EI and ES taxa in other regions will expand the utility of this approach for examining animal water-use and terrestrial aridity in additional paleontological, archaeological, and modern systems.

After the impact, Pluto and Charon accrete some of the debris and eject the rest from the binary orbit. During the ejection, high-velocity collisions among debris particles produce a collisional cascade, leading to the ejection of some debris from the system and enabling the remaining debris particles to find stable orbits around the binary. Our numerical simulations of coagulation and migration show that collisional evolution within a ring or a disk of debris leads to a few small satellites orbiting Pluto-Charon. These simulations are the first to demonstrate migration-induced mergers within a particle disk. The final satellite masses correlate with the initial disk mass. More massive disks tend to produce fewer satellites. For the current properties of the satellites, our results strongly favor initial debris masses of 3-10 X 10 (super 19) g and current satellite albedos A nearly equal 0.4-1.

For instance, the iterative development of meridional ornamentation is a diagnostic criterion used to discriminate between the Santonian-early Campanian genus Costellagerina, and the Campanian-Maastrichtian genus Rugoglobigerina. An alternative ecophenotypic explanation for differences based on observed poleward decreases in meridional ornamentation has not been widely accepted largely due to absence of evidence. Our study of Rugoglobigerina specimens recovered at three mid-low latitude localities (Exmouth Plateau, eastern Indian Ocean; Shatsky Rise, northwestern Pacific Ocean; Eratosthenes Seamount, eastern Mediterranean) confirms that meridional ornamentation is a primary character of their tests, but development of this feature is highly variable throughout the geographic and stratigraphic distribution of the genus. Within assemblages of Rugoglobigerina, there is a continuous morphological range from specimens with well-developed costellae arranged in a meridional pattern to specimens with relatively short ridges that are randomly oriented to meridionally aligned. Stable isotope (delta (super 13) C and delta (super 18) O) analyses indicate that specimens showing a more strongly developed meridional ornamentation consistently yield higher delta (super 13) C values than co-occurring less ornamented morphotypes at each examined locality, whereas patterns in the delta (super 18) O values are site-dependent. Interpretation of these patterns is not simple and might be related to different controlling factors acting together or separately. Potential explanations for the differential development of the ornamentation include: (1) adaptation to different ecological niches within a population, (2) species-level genetic differences, (3) variation in metabolic rate or activity within individuals, and (4) changes in the seawater carbonate ion saturation through space and time, including seasonality. In addition, we highlight the difficulty of discriminating between Rugoglobigerina and Costellagerina when they co-occur in lower Campanian deposits and among Rugoglobigerina, Costellagerina and Archaeoglobigerina at high latitude localities where species placed in all three genera show very similar shell morphology and ornamentation. Finally, our study challenges the general assumption that some external features of the wall are sufficiently reliable for taxonomic discrimination of Cretaceous planktonic foraminifera. This latter conclusion suggests that environmental conditions such as water temperature, water column stratification, nutrient concentration and carbonate ion saturation may have played a key role in triggering the external expression of genetically controlled wall ornamentation in the planktonic foraminifera.

Despite this trend, there are relatively few works that illustrate how research collaborations have affected scholarship. In this paper, I demonstrate how the use of collaborative methodologies has allowed me to better understand indigenous knowledge of Wounaan in eastern Panama. In particular, I examine the use of three different aspects of collaboration-codesigning research, coanalyzing results, and coauthorship-with local experts, leaders, and communities over 17 yr and how they have enriched my research on ethnoecology, political ecology, and linguistic anthropology. I also address how this solitary reflection has underscored the importance of process and multivocality in collaboration. The results illustrate how collaborative methodologies may engage different aspects of indigenous practice than participant observation, and how both methods mutually reinforce enhanced understanding of indigenous knowledge and the production of science.

This biostratigraphic system has served as the foundation for correlation between deposits on every continent. Despite their stratigraphic importance and the robust taxonomic knowledge of this group, relatively little attention has been given to their long-term diversity dynamics (i.e. patterns of diversity and taxonomic turnover rates as measured by extinction and origination) and the possible evolutionary controls underlying them. Consequently, this study aims to quantitatively establish the long-term genus-level diversity dynamics of ammonites prior to the K/Pg mass extinction event and then assess their possible relationships with abiotic controls during the Jurassic through latest Cretaceous ( approximately 130 millions of years). Changes in regional and global ammonite diversity (D), origination rates (OR), and extinction rates (ER) during this time span are compared at different spatial scales (i.e., regional vs. global) to examine the possible role of local and global geographic controls (i.e., open-shelf vs. epeiric sea, latitudinal gradients). Furthermore, to identify possible underlying environmental influences on D, OR, and ER, diversity dynamics will be assessed relative to a suite of various abiotic constraints, including: marine mean global temperature, productivity, as well as marine nutrient recycling and input as measured by sea level and isotopic proxies (i.e., d (super 18) O, d (super 13) C, d (super 34) S, (super 89) Sr/ (super 87) Sr, respectively). Results from this study will provide critical information on ammonite long-term diversity dynamics during an interval that documents a major diversification event in this group. Moreover, considering that ammonites have been one of the most successful (as measured by their abundance and taxonomic diversity) marine groups in Earth history prior to the K/Pg mass extinction event, such information is fundamental to developing a more thorough understanding of the long-term marine evolutionary processes and the biotic impacts of mass extinctions.

To test this, we compared the flora and herbivorous insect feeding traces from the Early Eocene Climatic Optimum in the neighboring Bighorn (BHB) and Wind River (WRB) Basins of Wyoming. We conducted unbiased floral counts at eleven localities along a laterally extensive carbonaceous shale bed in the BHB and at eight localities along a lithologically similar horizon in the WRB. The insect herbivore fauna was assessed by censusing insect feeding damage on fossil leaves at seven of the BHB and eight of the WRB localities. Geochemical analyses were conducted to complement the macrofossil data. Paleoclimate estimates indicate similar mean annual temperatures and slightly wetter conditions in the WRB. The most abundant species at both sites are taxa common throughout Eocene deposits in the Western Interior (ferns Lygodium kaulfussi, Salvinia preauriculata, and Equisetum sp.; monocot Zingiberopsis isonervosa; and dicots Platycarya castaneopsis, "Dombeya" novi-mundi, and Populus wyomingiana); five of the top ten most abundant species at each site are shared, although rank orders are different. However, there are important differences between basins. The most abundant species in the pooled BHB data is a conifer, whereas not a single conifer macrofossil or terpenoid was found in the WRB carb shale. Alnus, an important component in the BHB and many other Eocene floras, is also absent in the WRB censuses. Overall, of the 44 plant taxa found in the WRB sites, only 13 are also found in the BHB, indicating little overlap in rare species. Floral diversity is higher in the WRB, but, interestingly, damage diversity is lower. The range in damage diversity and prevalence among host plants is greater in the BHB, as would be expected for a drier environment. Damage composition on individual hosts is somewhat different at the two sites, but no significant differences in damage diversity or prevalence exist on the abundant species found in both basins. Our results support high endemism in the temperate zone during the height of EECO warming.

These and other speleothem oxygen isotope records of deglacial climate in western North America suggest important linkages between precipitation variability in this region and changes in global climate such as Arctic temperature and Asian monsoonal strength. However, these linkages have not yet been systematically investigated. We present a network visualization of 20 high-resolution oxygen isotope records from speleothems covering 10-20 ka, and four other key climate archives from ice cores and marine sediments. Significant positive correlations exist among the majority of North American records, including the Sierra Nevada speleothems, indicating generally coherent patterns of regional climate change at the scale of this analysis. One noteworthy exception to coherence is observed at Cave Without a Name (CWN), located farthest to the southeast in Texas, which shows a strong negative correlation with other regional records. Important global teleconnections also emerge from our analysis. Strong positive relationships exist between CWN, Hulu (China), Moomi (Yemen), and Chauvet (France) Caves and between these and the Cariaco Basin. Most North American caves display negative correlations with Hulu, Chauvet, and Cariaco. Strong negative relationships emerge between Sanbao (China) and Sofular (Turkey) Caves and between Sofular and the Cariaco Basin. The NGRIP ice core record displays positive correlations with most North American records and negative correlations with Asian and European records, while the EPICA Antarctic ice core record shows positive correlations with some North American records (ML, Fort Stanton, Cave of the Bells). Although some important connections occur between the northern and southern hemispheres, the strongest connections persist across the northern mid-latitudes, highlighting the importance of the Intertropical Convergence Zone and the westerly winds in transmitting information between these regions.

In June 2014 students from the University of the Andes (UniAndes) of Bogota, Colombia and undergraduate interns from the Panama Canal Project - PIRE program attended a field course in the Azuero Peninsula, Panama. Leading them were instructors and researchers from the University of Florida, Florida State University, UniAndes, the Florida Museum of Natural History, and the Smithsonian Tropical Research Institute (Panama). The goals of the trip were to create the first 1:25,000 scale map of 220 sq. kilometers in the western region of the Azuero Peninsula as well as to create original research and develop practical skills through self-proposed student projects spanning the sub-disciplines of geology including stratigraphy, petrology, geophysics, etc. Living and working with English and Spanish speakers of all skills levels necessitated constant communication of material, presented primarily in Spanish, across a language barrier. An immediate recognition of shared interests in the geosciences combined with the need to overcome daily challenges presented by working in the tropics (navigating streams and shorelines to find outcrops) gave all participants a common ground on which to build living and working relationships. Participants investigated distinct regions based on their project goals, necessitating the daily communication of their findings to the group in Spanish, a practice followed by all regardless of language skill level. Through the pursuit of original research, undergraduates gained a sense of ownership over mapping and individual projects. As geological research can often require international travel, there is a necessity for students to understand how to navigate and interact with professional counterparts from other cultures. This course gave students an opportunity to experience working in a foreign environment, surrounded by students from other cultures, with the intent to make original contributions to geology. As the area is little known to scientific literature, much of what was found will likely add to knowledge through research contributions from undergraduates at meetings and in journals.

Stratigraphic exposures up to 10 m thick were documented in Endurance and Victoria Craters. The bulk of these exposures consist of thick cross-bedded sulfate-rich sandstones overlain by eolian sulfate sand sheets that were altered by rising and falling water tables. In Endurance, these appear to transition vertically into aqueous ripples that have been interpreted to indicate interdune playa settings associated with rises in the water table above ground locally. The rover traverse crosses the modern eolian sand sheets and ripple fields and the subjacent surface of the Burns Formation where it has been exposed via "windows" in the eolian materials. The 40 km traverse includes approximately 80 m of elevation change, but the consistent morphology of the outcrop surface and gradual changes in elevation suggest the last process to act on the Burns Fm did so over the entire region--there are no mappable separate dune and interdune playa settings. The surface of the Burns Fm exhibits volume-loss cracking (desiccation?) at centimeter-, meter-, decameter-, and hundreds of meter-scales across the region, implying a lithologic homogeneity over much of the several hundred meter thick deposit. The Opportunity landing site includes a late Noachian to Early Hesperian population of degraded craters that must have formed within the deposit (at a few hundred meters to a few kilometers in diameter, they're too small to be protruding from beneath it), as well as a number of larger craters (10-20 km) that either clearly protrude from beneath the Meridiani deposits (Endeavour) or are superposed on all but the uppermost surface of the deposits (Bopolu, Iazu). We propose that the Meridiani deposits accumulated in a shallow marginal marine environment during a transgression of a northern plains ocean, associated with the Late Heavy Bombardment. After the late heavy bombardment ended, the ocean rapidly regressed.

There are different hypotheses about the life habits of this arthropod group and why they enrolled. These include: a planktic or epiplanktic habit, with the rolled-up posture resulting from clapping cephalon and pygidium together, ectoparasitic habit or a sessile lifestyle, either attached to seaweeds or on the sea floor. Herein we describe two new assemblages from the middle Cambrian of Purujosa (Iberian Chains, North Spain) where agnostids are minor components of the fossil assemblages but occasionally appear enrolled. The taphonomic and sedimentological data suggest that these agnostids were suddenly buried and rolled up as a response to adverse palaeoenvironmental conditions. Their presence with typical benthic components supports a benthic mode of life for at least some species of agnostids.

For Pennsylvanian-age, bituminous coals, peat:coal compaction ratios are commonly interpreted as 10:1 or more. Furthermore, compaction is generally accepted to be a long-term process associated with coalification, lasting perhaps millennia. Nadon (1998) argued for early compaction citing examples of geometrically preserved dinosaur tracks at the top of Cretaceous coals, among other data, as evidence. Several lines of evidence support early compaction in many Carboniferous coal beds: (1) The geometric relationship of clastic partings to coal beds along channel margins, (2) the geometry of seams containing coal balls relative to surrounding strata, (3) differential compaction and offsetting sandstones in successive depositional sequences, which suggest that compaction of underlying peats must have happened prior to deposition of the offset channels to have influenced subsequent paleotopography, (4) in widespread coalbeds, the lack of significant coal thickness change relative to position beneath sandstones (noncompacting) and shales (compacting), (5) relatively concordant bedding a short distance above scour-filling coals, (6) preservation of three-dimensional shape and lack of major discordance in laminations around in situ trees above coal beds, (7) sharp juxtaposition of low-ash coal benches beneath inorganic partings without mixing, and (8) a general lack of extensive soft-sediment deformation through partings in coals and in overlying siltstones, which might be expected to occur from dewatering of large interstitial water volume in the peat during compaction. When these criteria are examined, it appears that substantial compaction of original vegetation took place during and almost immediately after initial burial, with much of the remainder occurring within one depositional sequence of the burial of the peat. There may be a wide variety of compaction ratios for different types of peats in different environments.

However, these data are crucial for applications as diverse as paleoecological reconstruction and testing of climate models. The combined effects of Andean uplift, closure of the Central American Seaway, and global trends on Neotropical climate and environment during the Neogene remain uncertain. However, environmental conditions provide critical context for understanding biological evolution and events such as the Great American Biotic Interchange. We have undertaken a stable isotope analysis of fossil tooth enamel and pedogenic carbonate concretions to assess paleoclimate and terrestrial ecosystem structures in northern South America during the Miocene and Pliocene. The analyses presented here utilize material from the Castilletes Formation (early Miocene) and Honda Group (Middle Miocene) of Colombia and the Urumaco (Late Miocene) and San Gregorio (Pliocene) Formations of Venezuela. In particular, we have measured (a) the phosphate oxygen and carbonate carbon and oxygen isotope compositions of mammalian teeth, (b) the carbon and oxygen isotope compositions of pedogenic carbonate concretions, and (c) the phosphate oxygen isotope composition in fish teeth. Our studies have ensured that the fossil enamel preserves original isotopic signals as well as conducting investigations into paleotemperature, seasonality, and ecosystem structure. The fauna selected for this study allow an assessment of change in each of these variables over space and time. Furthermore, we compare the results for each time interval with existing climate estimates from synchronous mid latitude localities. Ultimately, these low latitude data help to constrain models of both physical environment and biological evolution throughout the Neogene.

However, it is among the insects, represented by the vast collection at Capital Normal University that the greatest amount of autecologic data has been generated, revealing associations of insects with coexisting plants, vertebrates and other insects. We present five categories of interspecific and intraspecific interactions representing six insect orders. (1) The long-proboscid pollination mode, a pollinator mutualism independently arrived at by Diptera (flies), Mecoptera (scorpionflies), Neuroptera (lacewings) and probably Lepidoptera (moths) that evolved convergent siphonate mouthparts. Mouthparts of these major insect lineages represent a broad mosaic of proboscis lengths and aspect ratios, terminal sponging structures, associated palp modifications and sucking pumps involved in imbibition of pollination drops from tubules or channels of gymnosperm ovulate organs, resulting in pollination. (2) Mimesis or camouflage was an association in which two lacewings imitated a co-occurring pinnate gymnosperm pinnule; similarly, a scorpionfly mimicked in facsimile fashion an entire co-occurring ginkgo leaf, presumably providing protection alike to both plant model and insect mimic. (3) An insect-vertebrate association consisting of a basal lineage of Siphonaptera (fleas) possessed mouthparts of long, robust, outwardly serrated stylets for piercing thick vertebrate integument and imbibing the blood of hosts, possibly feathered dinosaurs, pterosaurs and mammals. (4) Intraspecific interactions of insects include a pair of copulating Hemiptera (froghoppers), hitherto the earliest record of copulating insects. (5) Equally spectacular are two genera of Mecoptera with exaggerated male organs, likely representing the earliest example of long-term male-male competition in insects. These five mid-Mesozoic associations provide an augmented understanding of the role that insect speciosity had on a variety intimate and intricate ecologic relationships between insects and other contemporaneous associates of mid-Mesozoic ecosystems as well as intraspecific, evolutionary changes.

There are different opinions about its age. As the parastratotype of the Hezhou Formation, the Fenghuangshan section has more complete exposure than the stratotype, making it an ideal locality to study the foraminiferal succession and transgressive-regressive depositional cycles. In the Chinese Carboniferous foraminiferal scheme, the Eostaffella hohsienica foraminiferal zone, which was first identified within the Hezhou Formation, has unclear chronostratigraphic limits. Based on specimens from the Fenghuangshan section, this long-ranging zone can be replaced by three zones of cosmopolitan species. In ascending order, they are the Asteroarchaediscus Zone (latest Visean?-early Serpukhovian), Eostaffellina paraprotvae Zone (late Serpukhovian), and Monotaxinoides transitorius Zone (latest Serpukhovian). From detailed field measurements and thin section studies, twelve major microfacies and five transgressive-regressive cycles are recognized in the Hezhou Formation. According to the Pennsylvanian foraminifers found in sediments infilling the karsted limestone that forms the uppermost part of the Hezhou Formation, the debate on the cause of this karst surface can be resolved. It was a result of long-term karstification from the early Bashkirian to early Moscovian.

Constraining the spatial and temporal context of CAS shoaling, however, is hindered by ambiguity in the stratigraphic relationships and depositional environments of marine sedimentary exposures in Panama and adjacent regions. Here, we present new information from the Alhajuela Formation (Lago Alajuela, central Panama) with implications for the presence of the CAS in the Panama Canal and Lago Alajuela Basins. The age and stratigraphic relationships of the Alhajuela Formation are problematic due to its geographically-restricted exposures and lack of contacts with other age-constrained formations in Panama Canal Basin. Recent discoveries of a vertebrate assemblage from basal strata of the Alhajuela Formation suggest a middle-late Miocene age contemporary with the proposed onset of shoaling, yet the stratigraphy exposed in Lago Alajuela exhibits a transgressive transition from nearshore facies to shallow shelf environments. Matrix-supported conglomeratic horizons containing volcanic clasts, fossil terrestrial mammals, wood fragments, and marine vertebrates and invertebrates exhibit erosional contacts with underlying bioturbated marine sandstones with exclusively marine fossil content. Other mollusc-bearing sandstone units exhibit thin conglomeratic beds and lenses. We interpret these lithological sequences as representing conglomerate deposition in nearshore environments via subaqueous debris-flow and current-reworking processes, respectively. Higher in the stratigraphy, sediments comprise massive, carbonate-cemented, tuffaceous sandstone with exclusively marine fossil content, interpreted as shallow shelf deposits. This transgressive sequence in the Alhajuela Formation is consistent with the overall trend in paleobathymetry recently reported for the late Miocene Gatun Formation, which is either contemporaneous or slightly younger than the Alhajuela Formation. We conclude that the Panama Canal Basin did not serve as a major conduit for the mixing of Pacific-Caribbean waters. Rather the sedimentary record in this basin records an increase in accommodation space during the middle-late Miocene.

The interval is marked by a 5-8 degrees C temperature increase within 20 ka, a approximately 4-6 ppm negative carbon isotope excursion (CIE), and widespread marine carbonate dissolution. Together, these are strong evidence for a massive addition of isotopically light carbon into the exogenic carbon cycle. Despite agreement that the PETM reflects a large carbon cycle perturbation, atmospheric CO (sub 2) concentrations (pCO (sub 2) ) are poorly constrained. In this study we reconstructed Paleocene-Eocene pCO (sub 2) using the stomatal index proxy on leaf fossils of Ginkgo adiantoides from the Bighorn Basin, Wyoming. Multiple studies have examined the relationship between pCO (sub 2) and stomatal index for extant Ginkgo biloba. Though widely used, these previous calibrations had sparse data or were improperly constructed. We collected new data on stomatal index from herbarium specimens and living trees of Ginkgo biloba that grew under a range of pCO (sub 2) from 290-429 ppm. All specimens were macerated using Cr(VI)O (sub 3) and the internal view of the lower epidermis was imaged by environmental SEM. The new data show a significant decline in stomatal index with increasing pCO (sub 2) , but with a shallower slope than previously reported. Applying the new calibration curve to fossils of the nearly identical Ginkgo adiantoides, we reconstruct pCO (sub 2) between 300-350 ppm during a 500 ka period of the late Paleocene. However, in the 150 ka preceding the CIE, pCO (sub 2) rose quickly to as much as 750 ppm, remaining at least 660 ppm immediately after the recovery from the CIE. Inferred pCO (sub 2) returned to approximately 300 ppm during the earliest post-PETM (biozone Wa1), but rose again in the early Eocene. No Ginkgo fossils were found in the PETM. The doubling of pCO (sub 2) in the latest Paleocene coincides with a approximately 5 degrees C temperature increase inferred from delta (super 18) O in mammalian tooth enamel and fossil leaves; all data sets were generated from fossils in the Bighorn Basin. Our pCO (sub 2) data derived from Ginkgo is consistent with previous estimates of full Earth-system temperature sensitivity to pCO (sub 2) doubling. Relatively enriched CO (sub 2) from submarine volcanism could have warmed latest Paleocene climate without changing the isotopic composition of the exogenic carbon pool, triggering the release of depleted carbon reservoirs at the onset of the PETM.

Bellerophon is currently assigned over 150 species in the Paleobiology Database, and is likely a "wastebasket" taxon. Analyzing these taxa at the species level is thus important not only to improve taxonomy, but also to uncover origination and extinction dynamics, and trends in morphologic evolution. These planispiral coiled snails are found in both carbonate and siliciclastic rocks, resulting in a variety of preservational modes that must be accommodated when scoring character states. Published images as well as specimens selected from invertebrate paleontology collections were used to examine 41 taxa, which were coded for 137 states among 64 characters. Several of these are continuous morphometric characters that are treated as "ordered" series and weighted by 1/(n-1), where 'n' designates the number of character states. Shell characters in conjunction with stratigraphic data were analyzed using stratocladistics, with stratigraphic bins of 5 million years each. Aglaoglyptia, Pharkidontus, and Mogulia were used as outgroups in the phylogenetic analysis. As expected given its taxonomic history, Bellerophon was found to be a paraphyletic relative to several other genera in Bellerophontidae. In some cases, these other genera may be monophyletic groups (e.g. Aglaoglyptia). However, the outgroup Pharkidontus appears to be polyphyletic, suggesting the features linking Pharkidontus and Bellerophon are convergent. Among species assigned to Bellerophon, multiple clades were recovered that should be considered for classification as unique genera. In particular, the oldest clade from the Carboniferous displays a distinct loss of filling around the coiling axis, while maintaining a sharp sinus. This is unique from the majority of Bellerophon species, which shows filling around the coiling axis in addition to a sharp sinus. Additionally, features such as columella thickness and orientation, as well as tighter coiling, were important in differentiating species within Bellerophon.

Major efforts have been made to compare the current estimates of extinction rate, which is heavily based on terrestrial vertebrates, to rates in the fossil record, which are primarily calculated using marine invertebrates (Barnosky et al. 2011, Nature). Our alternative approach is to ask whether species that are either threatened or have recently gone extinct have a fossil record. That is, in the absence of the historic record, would the existence of these species be known in the future? This method of determining the "future fossil record" should allow a more reliable comparison of current and fossil record extinction metrics. We have applied this approach to examine terrestrial mammals. We also ask if particular characteristics (e.g., trophic level, taxonomic affiliation and body size) influence the tendency for animals to appear in the record. The current IUCN Red List of Threatened Species (super TM) lists 714 species of mammals in the categories Extinct (E:75 sp.), Extinct in the Wild (EW:2 sp.), Critically Endangered (CR:194 sp.), and Endangered (EN:442 sp.). This list was compared with the fossil mammal record from three commonly used databases: the Paleobiology Database, Neotoma, and NOW. Body size data were obtained from the MOM v4.0 database. Of the 714 red-listed mammal species, only 89 (12%) appear in at least one of these databases. We find a strong signature of taxonomic affiliation, which may be size related. For example, while only 13 of 250 rodents (5%) have a record, 23 out of 64 cetartiodactyls (36%) do. The record improves somewhat if we use fossil genera; the total representation in the fossil record rises to 62%, with 49% of threatened rodent species having a congener in the fossil record. We also find a substantial overall size signature: the probability of taxa represented in the record being larger than those missing. The log-mass for species in the fossil record is much larger than that of the Recent species, reflecting the underrepresentation of small body size taxa such as chiropterans. The record of ancient extinctions may have been similarly biased.

Most studies of mass extinctions have compared the pre-extinction biota with survivors to infer patterns of selectivity, largely because we lack the temporal resolution to interrogate the internal dynamics of the great mass extinctions or other biodiversity crises documented by the Phanerozoic fossil record. But as improved geochronology, statistical analysis and correlation methods increase the resolution of extinctions intervals paleontologists have greater opportunities to probe extinction dynamics. Recent high-resolution radiometric dating of the Permo-Triassic, Triassic-Jurassic, Cretaceous-Paleogene has revealed that these events were far more rapid than previously appreciated (maximum durations of 61 + or - 48 ky, <5 ky and 5 + or - 27 ky, respectively); some smaller crises may have been similarly brief. Given the evidence for different triggers for these events, this suggests that mass extinctions, independent of their physical drivers, invoke similar patterns of biotic collapse. Application of concepts from network dynamics may help discriminate between the contributions of biotic and abiotic contributions, as alternative distributions of loss of taxa across a network of ecological interactions imply very different patterns of biotic collapse.

We are researching variations in atmospheric dustiness during the late Paleozoic and assessing effects of dustiness on the biosphere. Our goals are to constrain spatial and temporal variations in atmospheric "dustiness," dust provenance, and influences between dust and ecosystem composition to clarify the relationships among atmospheric dustiness, climate, and the biosphere. Here we present preliminary data from two time intervals (Moscovian or middle Pennsylvanian) from the Copacabana Formation, Madre de Dios Basin (Bolivia). Two sections of approximately 15 meters each representing carbonate inner platform environments were processed to isolate the fine-grained silicate mineral fraction (SMF). Given the proximity to arc volcanism there is potential for ash to disrupt the aeolian dust signal; initial work is aimed at assessing the volcanic versus continental inputs to the basin as well as addressing our primary goals. Visual inspection and initial physical - chemical measurements of the dust-loess size fractions indicate differences between the upper and lower sections, as well as between ash-rich and ash-poor intervals. The lower section has intervals with up to 72 weight-% suspected ash and SMF (non-ash) of 1-7%. The suspected ash layers in the lower section have larger grain sizes (20-40 mu m) and distinct (super 143) Nd/ (super 144) Nd isotopic compositions (epsilon (sub Nd) = -3.5, -3.8) compared to the ash-poor intervals ( approximately 8 mu m, epsilon (sub Nd) = -5.0 to -8.8). The upper section, free of visible ash layers, has high SMF (mean 4-7% up to 41%) with similar size distributions (6-11 mu m) and epsilon (sub Nd) (-7.4 to -7.7) to the lower section, but more radiogenic (super 87) Sr/ (super 86) Sr compositions (0.797 versus 0.71 - 0.75). Qualitatively, the ash-influenced intervals exhibit abundant evidence for biological activity (bioturbation). The combination of distinct physical and isotopic characteristics of the ash and SMF in the sections and sub-intervals, and the correlation with biological productivity, suggests that (1) deconvolving ash and aeolian inputs to the marine biosphere is possible and (2) dust provenance may influence nutrient availability.

Here we use a multi-proxy approach (pedogenic carbonate paleobarometry, fossil leaf stomatal index, and a plant physiology-based model) to reconstruct paleo-CO (sub 2) variability over the late Carboniferous. Paleo-CO (sub 2) estimates ( approximately 300 to 900 ppmv) are comparable to the anticipated shift in CO (sub 2) from preindustrial to projected levels under a spectrum of energy-economic models - levels that greatly exceeded those of the Cenozoic icehouse. Integration of paleo-CO (sub 2) with sedimentologic, paleosol and fossil plant proxy records have the potential to provide unique insight into how physical, chemical and terrestrial ecosystem processes and associated feedbacks in the Earth system functioned during an icehouse under evolving atmospheric CO (sub 2) concentrations. Our late Paleozoic climate models suggest that vegetation-CO (sub 2) -climate feedbacks had the potential to push the climate system between glacial and interglacial states and to strongly modify the climate regime within these states. Documented shifts in the composition of paleotropical flora between inferred glacial and interglacial states within eccentricity-paced cycles - and on million-year time-scales - further support a key role of vegetation-CO (sub 2) -climate feedbacks in climate transitions. This Earth-Life Transitions collaborative research integrates empirical, plant growth chamber experimental, and modeling approaches over a spectrum of time- (10 (super 1) to 10 (super 6) yr) and spatial-scales (leaf-to-canopy-to-global climate system) to critically evaluate the roles of CO (sub 2) - and orbital-forcing and vegetation-climate feedbacks in promoting glacial-interglacial transitions during the LPIA. The nature of this hypothesis-driven research and preliminary results will be overviewed in this presentation.

Our studies in the Patuxent River (a subestuary of Chesapeake Bay) and its tributary creeks suggest successive waves of population spread and trophic influence of these 2 gelatinous species in opposing directions across the aquatic landscape. In years when both species were abundant, Mnemiopsis appeared first in the main channel of the Patuxent River and initially was most abundant in the bottom layer of the water column. Mnemiopsis densities then rapidly increased in shallow tributaries and coves, with distributions likely caused by a combination of transport and temporally and spatially varying patterns of growth and reproduction. In contrast, densities of Chrysaora ephyrae were initially highest in small coves and tributary creeks, with densities of Chrysaora medusae spreading outward from these small systems to the main river as summer progressed. We found no conclusive evidence for tidally-cued vertical migrations of either species or directional swimming by Chrysaora that would create these differing spatio-temporal patterns. As Chrysaora increased and spread, it likely reduced or eliminated Mnemiopsis by direct predation, and possibly through the effect that partial predation could have on Mnemiopsis reproduction. Because of differences in diets and feeding rates, these shifting temporal and spatial patterns of medusa and ctenophore dominance potentially influence spatial distributions and temporal patterns of survival of ichthyoplankton, oyster larvae, and copepods.

Because mangroves live at the interface of land and sea, both terrestrial and marine species affect them, including numerous herbivores and boring species. These organisms can affect the fecundity, performance, and morphology of mangroves. In a mangrove stand in southwestern Taiwan, we discovered that mangroves were extensively damaged by wood-boring isopods Sphaeroma terebrans. We examined the relationships between burrowing damage from S. terebrans and metrics of mangrove fecundity, performance, and morphology. Individuals of Rhizophora stylosa that were more burrowed by isopods had significantly fewer propagules, fewer ground roots stabilizing the tree, smaller leaves, and more non-foliated twigs. Similarly, Avicennia marina with more burrows had fewer pneumatophores and lenticels (used for gaseous exchange), and pneumatophores with more necrotic tissue. The most heavily damaged trees were hollowed-out with burrows (A. marina) or fell over when their supportive root system failed (R. stylosa). These correlations suggest that marine wood-borers can negatively influence mangroves and alter tree morphology, although other stressors may also be involved. While studies have examined the effects of isopods on root-level production, we provide the first quantitative evidence that localized burrowing damage is correlated with tree-level effects. These results are consistent with other literature demonstrating the importance of sub-lethal damage by borers in shaping foundation species. Such damage may have cascading effects on the diverse assemblages of marine and terrestrial biota that use mangroves as habitat.

At its type locality, the Upper Cretaceous (upper Maastrichtian) Owl Creek Formation offers an excellent opportunity to examine the depth habitat of juveniles and adults from three common ammonite families, the Baculitidae, Scaphitidae, and Sphenodiscidae, by comparing the isotopic composition of their shells to that of co-occurring planktonic and benthic organisms. Based on sediment composition and structures, and the micro- and macro-fauna of this outcrop, we infer a fully marine environment below wave base, approximately 50 to 70 m paleodepth. About 400 bivalve, gastropod, and ammonite specimens were collected from the 9 m thick exposure. Fossils were SEM'ed to screen for alteration; approximately 200 specimens were found to be well preserved. From these, we made over 300 isotopic measurements. In addition, planktonic and benthic foraminifera were picked from five stratigraphically dispersed horizons, resulting in 11 isotopic measurements of planktonic foraminifera and 14 of benthic foraminifera. No stratigraphic trends are observed in the isotopic data of any taxonomic group. We estimate local bottom water temperatures via oxygen isotopes (delta (super 18) O) from benthic foraminifera, bivalves, and gastropods; serial samples from bivalve shells constrain seasonal seafloor temperature fluctuations. Surface water temperatures are estimated from the delta (super 18) O of planktonic foraminifera. The delta (super 18) O of baculitids and scaphitids suggest that they lived close to the seafloor. The range of variability in their isotopic data is similar to that seen in the seasonal profiles of bivalves, implying that these ammonites lived in one region and did not migrate with currents of a particular temperature. In contrast, the oxygen isotopic values of the sphenodiscids align with those of the planktonic foraminifera, implying that they inhabited the upper water column. This, combined with their rarity and poor preservation relative to the baculitids and scaphitids, suggests that perhaps the sphenodiscids lived closer to shore than the studied outcrop, and drifted seaward after death. These results provide evidence that the Baculitidae and Scaphitidae were nektobenthic/demersal, while the Sphenodiscidae lived within surface waters.

We conducted extensive fieldwork in stratigraphy and paleontology to document the transition from the fully marine environment of the Jimol Formation ( approximately 19-17.3 Ma) to the shalllow marine to fluvio-deltaic environment of the Castilletes ( approximately 17.3-14.5 Ma) and Ware Formations ( approximately 3.5-2.8 Ma). The Jimol Formation reveals the Cocinetas Basin as a shallow marine environment from 19 Ma up to 17.3 Ma. Diverse shallow marine invertebrate communities and oyster banks flourished in a carbonate shelf during high sea level periods, while coarse calcareous and lithic sandstones were deposited in shoreface environments during low sea level stages. Mudstones of shoreface and backshore environments record the lowest sea level episodes. In the Castilletes Formation, storm events, oyster banks, and shore-face deposits vary laterally to estuarine, fluvio-deltaic plains and deltaic channel deposits, revealing the transition to fluvial dominated environments from 17.3 Ma up to 14.5 Ma. The vertebrate fossil assemblage contained in the terrestrial intervals of the Castilletes and Ware Formation provide new insights into the paleoecological history of Guajira Peninsula. Semi-aquatic organisms as crocodiles, turtles, and astrapotheres suggest the presence year around freshwater bodies. Furthermore, grazing and browsing herbivores as astrapotheres and proterotheres, respectively, suggest grasslands and forests dominating the landscape of the Guajira peninsula up to 2.8 Ma ago.

As recently as 14 ka, millions of large-bodied mammals including mammoth, camels, llamas, saber-tooth cats and short-faced bear were widespread across the Americas. Within 1,000 years of the arrival of humans, approximately 80% of these large-bodied mammals were extinct, including all over 600 kg. While the cause of the extinction remains somewhat contentious, humans likely played a crucial role through a combination of hunting and habitat alteration. What has been largely overlooked in this debate, however, is the consequence on ecosystems of the loss of millions of large-bodied animals. Our work focuses on Hall's Cave in the southern Great Plains of Texas; a site with an exemplary temporal record with continuous representation over the past 20 ka. Here, we examine the community level response to the catastrophic loss of 80% (12/15 species) of the local large-bodied herbivores, and 20% (3/15 species) of the apex predators in the ecosystem. Using 8 tightly constrained temporal windows, which span from the full glacial to the modern, and site-specific faunal lists, we reconstruct the local mammal body size distribution. We analyze both the shape and composition of the distribution, as well as species associations, to assess the influence the megafauna extinction had on the remaining mammals in the community. Overall, we see a pattern of consistency: species diversity and the statistical moments do not vary substantially across time. Although all metrics of body size are greater at the Full Glacial and a drop in maximum size is seen in the early Holocene, the median and mean size are roughly constant across most the past 20 ka. Pairs analysis yields no significant pattern of association or disassociation across these temporal windows, suggesting that mammals responded individualistically to the loss of megafauna and climate shifts over this time period.

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

I. Abiotic conditions and biological responses AN - 1660405363; PQ0001173382 AB - We report on results of a microcosm experiment to study the interactive effects of elevated CO sub(2) , high organic and inorganic nutrient loading, and high irradiance on phytoplankton and bacterioplankton from the Mediterranean coastal ecosystem of the Alboran Sea. This experiment was part of the Group for Aquatic Productivity 9th international workshop and was conducted by Working Group 1 (WG1: Phytoplankton of coastal waters, www.gap9.uma.es). Over a 7 d period, we measured the variation in physical and chemical variables and the characteristics of phytoplankton and bacterioplankton in microcosms incubated under 8 treatments, representing full factorial combinations of 2 levels each of CO sub(2) supply, nutrient concentrations and solar radiation exposure. For each treatment combination, we incubated triplicate microcosms consisting of 20 l polyethylene bags which were transparent to ultraviolet radiation. Sustained growth of phytoplankton biomass (chl a) occurred in all treatments. The absence of mesozooplankton in the microcosms resulted in a trophic cascade. Picophytoplankton were initially stimulated but then decreased, apparently due to microzooplankton grazing, and were largely replaced by diatoms. Bacteria were also initially stimulated and then decreased, but eventually recovered. Responses were modified markedly by nutrient enrichment and light availability, with moderate effects of elevated CO sub(2). Relative to ambient CO sub(2), elevated CO sub(2) resulted in higher chl a under low irradiance, but lower chl a under high irradiance.

Even though many factors affect corals, we have very little data on the relationship between multiple co-occurring stressors and their compounding effects on these critical ecosystem engineers. We provide evidence that under short-term exposure, the presence of the brown alga Dictyota menstrualis has direct negative consequences for coral survival and recruitment, while seawater elevated to +3.5[degrees]C causes sublethal stress and compromises coral health. Three lifehistory stages (larvae, 6 wkold juveniles [~0.15 cm super(2)], and 1-2 yr-old colonies [0.8-45 cm super(2)]) of the common Caribbean coral Porites astreoides were exposed to each stressor alone and in combination. Exposure to D. menstrualis reduced the survival of P. astreoides larvae and 6 wk-old juveniles by ~40% and caused partial mortality in 1-2 yr-old colonies. Elevated temperature did not cause mortality, but induced sublethal stress that was disparate among coral lifehistory stages. These stressors in combination predominately impacted corals in an independent manner. However, extended exposure resulted in a synergistic enhancement of oxidative damage (lipid peroxidation) in P. astreoides larvae. Our results suggest that benthic macroalgae can greatly inhibit coral recruitment, and this pressure combined with rising seasurface temperatures represents a significant threat to the health of coral reef ecosystems. These results highlight the importance of local- and global-scale stressors acting in concert to impact coral demographics during critical early life-history stages.

AN - 1656039213; 2015-015996 AB - Advances in developmental evolutionary biology have greatly increased our understanding of how morphological features are constructed and how development shapes their change through time. It is now clear that developmental gene regulatory networks are highly conserved and often rigidly associated with particular morphologies. The complex wiring of these networks imposes lineage-specific constraints upon rates and patterns of morphological character evolution. Because morphology, whether fossil or recent, is the outcome of developmental process, basic principles from living systems may be used to help constrain fossil phylogenies. To explore the usefulness and contribution of developmental information to phylogenetic analyses, I applied a Bayesian phylogenetic approach to existing morphological datasets, including those from a problematic and character-depauperate group, the lobopods. Lobopods are currently thought to represent a basal grade leading to extant onychophorans and arthropods, but the phylogenetic relationship among fossil lineages is difficult to decipher on fossil morphology alone. I compared models designed to accommodate variation in evolutionary rate, both among characters and among (defined a priori) developmental character partitions, as well as asymmetric character transitions to determine if incorporating developmental information can better inform phylogenetic hypotheses.

The Earth2Class Workshops (E2C) at the Lamont-Doherty Earth Observatory of Columbia University (LDEO) provides one model for creating effective teacher training to meet the NGSS challenges. Since 1998, E2C has provided more than 130 workshops bringing together LDEO research scientists with classroom teachers from the New York metropolitan area and elsewhere. In each session, teachers have the chance to learn first-hand about new discoveries in the wide range of investigations conducted at LDEO. This approach aligns strongly with the NGSS goals: mastery of the disciplinary core ideas, science and engineering practices, understanding the nature of science, and cross-cutting relationships. Through the E2C website www.earth2class.org, teachers and students not able to attend the live workshops can access archival versions of the sessions. The website also provides a vast array of educational resources. These have proved to be very valuable on a national basis, as evidenced by an average of more than 300,000 hits per month from thousands of site visitors. During workshops, participating teachers interact with scientists to gain understanding of what stimulated research questions, how scientists put together all the components of investigations, and ways in which results are disseminated. Networking among teachers often leads to developing lesson plans based on the science, as well as support for professional growth not always possible within the school setting. During the next couple of years, the E2C program will expand to provide more resources useful for educators seeking to introduce NGSS-based programs in their districts. This approach can be applied in other settings, with appropriate modifications.

The entire sequence consists of 9 km of sediments accumulated in a subsidence trench that originated with the collision of the Caribbean and South America plates. The long sedimentary record expands across an area of 50 km (super 2) and allows for paleoenvironmental reconstruction over the last 17 Ma. Analysis of palynomorphs and facies at stratigraphic depth intervals of less than 60 m provide data on likely changes in biomes and environmental conditions from the early Neogene to Pleistocene in the Falcon area. The climatic history of the region, including the timing of the onset of these arid conditions and the evolution and establishment of this local xeric biome are still largely unknown. These arid climatic conditions were likely influenced by changes in ocean circulation initiated by the formation of the Panamanian Isthmus. Current regional climatic conditions are strongly governed by the annual migration of the Intertropical Convergence Zone (ITCZ), by westerly wind patterns, and by El Nino and Southern Oscillation (ENSO). Regionally, there is extensive aridity that extends from the Guajira peninsula and all the way west to the Falcon state, including the Paraguana Peninsula. The xeric environment that dominates the area supports vegetation that exclusively thrives under stressful climatic regimes. Our initial paleovegetation and paleoenvironmental reconstructions support the hypothesis of a change in the vegetation towards a xeric dominating type as a response to a striking climatic shift that induced a arid conditions in the area by the late Miocene.

Using measurements of seawater temperature, delta (super 18) O (delta (sub w) ), dissolved inorganic carbon delta (super 13) C (delta (super 13) C (sub DIC) ), and salinity values collected biweekly over a year, we tested the fidelity of shell delta (super 18) O and delta (super 13) C profiles to record delta (sub w) , delta (super 13) C (sub DIC) , and nutrient variations in tropical waters. Preliminary results from five Pacific cone snail (Conus) specimens suggest measured shell delta (super 18) O correlates with predicted shell delta (super 18) O calculated using delta (sub w) and water temperature. Seasonal upwelling in the Pacific drove higher amplitudes in shell delta (super 18) O ( approximately 1.5 ppm) compared with the Caribbean (<0.5 ppm). However, both Pacific and Caribbean shell delta (super 13) C profiles are relatively invarient, likely reflecting reduced seasonality in the Caribbean and overall lack of variability in DIC source in shallow environments on both sides of the Isthmus of Panama. Predicted shell delta (super 13) C curves approximated using measured delta (super 13) C (sub DIC) are approximately 1-2 ppm higher than actual shell delta (super 13) C (sub ) profiles, suggesting the incorporation of light metabolic C in Conus shells. In addition, we tested N-isotope ratios ( (super 15) N/ (super 14) N) in tissues and shell organic matrix of modern bivalves (Isognomon alatus, Pinctada imbricata, and Brachidontes exustus) as a proxy for natural and anthropogenic nutrient fluxes in coastal environments in the Bocas del Toro Archipelago (Caribbean), Panama. For all species, there is no consistent Delta (super 15) N (sub tissue-shell) offset between stomach, gill, mantle, and muscle tissues and shell delta (super 15) N values. Two species, P. imbricata and I. alatus show significant delta (super 15) N tissue-shell correlation. Heavily populated and river influenced sites show higher delta (super 15) N values on average (4.4 ppm) compared with open-ocean sites (3.2 ppm) in the Bocas del Toro Archipelago. Shell delta (super 18) O values corroborate delta (super 15) N interpretations of marine versus terrestrial influence with lower values (-1.5 ppm) in sites influenced by freshwater influx compared with open-ocean sites (-1.0 ppm). Our results show that O-, C-, and N-isotopes in mollusk shell carbonate and organic matrix are useful indicators of nutrient sources in the southwest Caribbean and eastern tropical Pacific.

These dominantly terrestrial deposits contain one to two 45-79 cm thick stromatolite beds and associated minor intraclast conglomerate. Above the Lykins lies strata of uncertain stratigraphic affinity, a 15.7 m thick unit of silty shale, fine sandstone, and thick crystalline gypsum layers, locally up to 10.7 m thick. At two localities, the top of this unit contains a thin (<1 m) well-known chert-bearing unit mapped extensively in the central and western U.S. as the base of the Morrison Formation. This bed, recognized for first time in the Colorado Springs area, marks a significant shift in facies from restricted marine basin deposits to freshwater terrestrial strata of the overlying strata that consist of gray sandstone, shale, carbonate mudstone, and up to three, 24-45 cm thick, stromatolitic lacustrian limestone beds. We correlate the latter to similar beds on the Comanche National Grasslands, approximately 250 km to the southeast. The carbonate beds at that locality include oolitic grainstone, freshwater ostracods, and dinosaur bones and footprints. Thin layers of organic rich shale to poorly developed coal in the uppermost beds of the evaporite succession have yielded pollen and sparse dinoflagellates. This is the first report of palynomorphs from this member. The low-diversity palynoflora is dominated by two species of fern spores, Ischyosporites marburgensis (Schizaeaceae) and Cyathidites minor (possibly the tree fern family Cyatheaceae), and the extinct conifer taxon Classopollis. Other rare taxa include Araucariacites spp. (representing the southern hemisphere family Araucariaceae) Exesipollenites tumulus (?Taxodiaceae), and bisaccates (?Pinaceae), as well as the dinoflagellates Spiniferites and Odontochitina. The assemblage resembles others previously recovered from elsewhere in the Morrison Formation, except for its much lower diversity. Classopollis is often indicative of drier conditions, but the abundance of two spore types (as well as the presence of coal) suggests wetter conditions, perhaps a local wetland with input from drier adapted plants occupying interfluves.

During the examination of the pegmatite using cathodoluminescence, fine-grained apatite was found to be widely distributed throughout the primary zones and replacement unit of the pegmatite. Millimeter- to micrometer-sized apatite was observed mainly disseminated in albite, and sparingly in microcline, quartz, lithian muscovite and montebrasite. Electron microprobe data provides evidence for the chemical evolution of apatite with respect to Mn enrichment during successive stages of crystallization of the pegmatite. The Mn content of apatite from the wall zone averages 4.1 wt.% MnO. The average Mn content of apatite during crystallization of the subsequent 1st intermediate, 2nd intermediate, and 3rd intermediate zones shows a steady increase of 1.5 wt.%, 2.5 wt.%, and 3.0 wt.% MnO, respectively. Within the tourmaline-lepidolite-albite and lepidolite-albite units of the 3rd intermediate zones, the MnO concentration of apatite drops sharply to about 0.6 wt.%, but increases again to nearly 2.0 wt.% in late lepidolite-bearing units. The last major unit to crystallize, the replacement body, contains apatite with an average MnO concentration of 1.3 wt.%, similar to apatite found in the 1st intermediate zone of the pegmatite. The non-linear behavior of Mn enrichment in apatite is attributed to the mineralogy of each zone, where accessory minerals may be present that have a higher affinity for Mn over apatite. Co-precipitation of manganocolumbite and elbaite provides competition for Mn in the melt and may be responsible for the sudden depletion of Mn in apatite from the 3rd intermediate zone. The competition of ions between different mineral phases gives insight in the fractionation patterns on Mn in Black Mountain and provides a possible pathway to determining the trace element chemistry throughout the evolution of the pegmatite.

I. Seasonal and spatial patterns AN - 1635036003; 21099901 AB - Daily rates of phytoplankton primary production were calculated from measurements of light saturation curves of photosynthesis for 20 yr at 6 stations on the Rhode River, Maryland (USA). Daily production, corrected for the geometry and spectrum of the underwater light field, averaged 1319 (range 1.4 to 15 800) mg C m super(-2) d super(-1). Log-transformation of the exact solution for depth-integrated daily production permitted linear analysis of seasonal and spatial patterns in production and the factors that determine it. The seasonal signal was the greatest source of variation, followed by spatial then interannual. The seasonal pattern was driven by coinciding summer maxima in both the chlorophyll a (chl a) biomass, B, and the light saturated photosynthetic rate normalized to chl a, P super(B) sub(max). The spatial pattern was characterized by a region in which production was relatively constant despite declining depth, a station at which production was reduced by truncation of the depth profile of production, and an area where mean production was lowest but variance was highest, due to local flow causing either localized blooms or washout of biomass and high turbidity at the station furthest up the estuary. Analysis of the components contributing to the variance in production indicated that variance in B and P super(B) sub(max) added nearly equally to it. Covariance between B and the light attenuation coefficient reduced the variance in production. The analytical approach adopted here allowed these patterns to be discerned against a high degree of overall variability, and should be similarly useful in a wide range of systems.

II. Interannual variations and modeling AN - 1635035973; 21099902 AB - A 19 yr time series of annual primary production in the eutrophic Rhode River subestuary of the Chesapeake Bay in Maryland (USA) was analyzed in relation to climatological and ecological factors. The objectives of this work were to understand factors controlling interannual variations in primary production in a eutrophic estuary and develop a model for tracking future variations in production, in the absence of direct measurements of photosynthetic carbon uptake. Annual production (P sub(A)) averaged 328 (range 152 to 612) g C m super(-2) yr super(-1). Interannual variability was statistically significant, but there was no significant linear trend or significant non-random variations over the available 19 yr. Climatological indices based on North Atlantic Oscillation or flow of the Susquehanna River, the principal N source to the upper Chesapeake Bay, were not significant predictors of P sub(A). A classification of years based on magnitude of the spring dinoflagellate bloom and timing of nitrate depletion was a significant predictor of P sub(A). Phytoplankton biomass, B, and the light saturated photosynthetic rate normalized to chlorophyll, P super(B) sub(max), were of similar magnitude in their influence on the variance in P sub(A). The high degree of variability in P super(B) sub(max) weakened efforts to model both daily and annual production from measurements of chlorophyll and light attenuation. Between 4 and 15 yr of measurements of chlorophyll and light attenuation would be needed to detect a change in trophic status of the sub-estuary, depending on the level of reduction achieved in P sub(A). Average daily production would have to be reduced below 1052 mg C m super(-2) d super(-1) to achieve mesotrophic status.

The purposes of this study were to investigate variation in sperm and seminal fluid quantities obtained during mating in mature female blue crabs Callinectes sapidus in Chesapeake Bay, USA, and to model potential effects of sperm reduction on lifetime brood production. We explored variation in sperm and seminal fluid quantity with respect to (1) season, (2) location, (3) operational sex ratio (OSR), (4) relative time since mating, and (5) fertilization, and used this information to model brood production. Mature female blue crabs were obtained from targeted or long-term collection efforts. Crabs were characterized by carapace condition, presence of a sperm plug (hardened seminal fluid), and presence of egg masses or egg remnants. They were dissected and processed to determine the quantity of stored sperm and spermathecae weight. Sperm quantity, but not spermathecae weight, of recently mated females varied seasonally and spatially, and was positively correlated with OSR. Females received as many as 3 x 10 super(9) sperm during mating, which declined to an average of 8 x 10 super(7) sperm before fertilization of the first brood. Both model simulations and estimates of sperm used for fertilization derived from sperm counts of females with and without evidence of spawning indicated that a reduction in lifetime brood production (sperm limitation) is likely in individual female blue crabs if they survive to a second spawning season.

The timing of synchronous larval release, postlarval migrations to adult habitat and diurnal vertical migrations are all considered adaptations to predictable variations in predation risk. However, despite the fact that predation risk is expected to vary predictably over time, this variation remains poorly understood for planktonic animals in the field. In this study, we conducted dock-based predation risk assays using tethered brine shrimp Artemia franciscana. We tested for the combined effects of prey life history stage and diurnal phase by measuring loss of adult and larval tethered individuals. We sampled during day and night, and during large and small amplitude tides on the Pacific coast of Panama. On the Caribbean coast of Panama and the Atlantic coast of Florida (where tidal amplitude is smaller), we sampled during day and night but did not test for an effect of tidal amplitude. Although predation risk differed between sites, the trends were the same at all 3 docks. Predation risk was significantly higher during the day than at night for larvae, whereas adults experienced the opposite trend in risk across the diurnal cycle, although the difference was not significant. Our results demonstrate a temporal gradient in planktonic predation risk across the diurnal cycle that depends on prey life history stage.

Chemoreception is integral to how larval fish find reef habitat and adult fish find home. Yet, the chemicals responsible for driving fish behavior are largely unknown, and the chemical seascapes through which fish navigate are changing with shifting environmental conditions. To investigate the possible suite of chemical cues employed by fishes in their search for foraging hot-spots, we collected 10 l samples of water from the center of natural foraging aggregations. These aggregations were composed of multiple fish species from several trophic levels over the reefs of Belize. We then conducted bioassays on wild-caught Ab udefduf saxatilis (N = 84) in laboratory flow tanks using previously frozen seawater samples and extracted compounds from foraging aggregations and paired control sites. Capturing seawater from the midst of natural foraging aggregations, filtering this over C18 resin, and presenting the eluted compounds to a reef fish elicited a significant behavioral response of spending more time in water that contained C18 extracts from fish aggregations compared to controls (p = 0.03). These results indicate that chemical cues collected within the middle of multi-species fish foraging aggregations are attractive to adult reef fish and suggest that chemical signatures associated with foraging aggregations might be important olfactory guides for fish.

Syndinean dinoflagellates that infect tintinnid ciliates and free-living dinoflagellates cause host mortality that can lead to the decline of blooms and promote species succession. Far less is known about the role of parasitism in aloricate ciliates and other protistan groups. Here, we provide data on parasitism of aloricate ciliates for seasonal samples collected from the southern coast of Korea over a 3 yr period. Aloricate ciliates were parasitized by species from 2 syndinean dinoflagellate genera and an unidentified genus of core dinoflagellates (Dinokaryota). Morphological and developmental differences among parasites of different host taxa suggest high parasite diversity. Infections generally peaked in fall, but notable interannual variation was evident within seasons. Parasites were more often encountered in commonly occurring and abundant hosts, but were also detected in occasional and rare host species. Most host taxa were rarely or sporadically parasitized, but Strombidium pollostomum and Strombidium bilobum were infected in 31 and 13 % of the samples, respectively, where the species were present. Parasite prevalence in those species reached 22 and 17%, respectively. Overall, 29% of the samples analyzed contained infected aloricate ciliates. Results indicate that parasites of aloricate ciliates are usually a minor source of host mortality in coastal waters of Korea, but may periodically produce high infection levels contributing to top-down control of particular host species.

The Batrachoididae, the only known family of the order Batrachoidiformes, includes 23 extant genera and about 80 species arranged in four subfamilies. A new genus and species of toadfish, Zappaichthys harzhauseri, gen. et sp. nov., is described from the middle Miocene (upper Badenian) Leitha Limestone of St. Margarethen in Burgenland, Eisenstadt-Sopron Basin, Austria. It is based on three partially complete, well-preserved articulated skeletons plus a neurocranium that display a unique combination of characters [possession of 29 (10 + 19) vertebrae; dorsal fin with three solid spines and 16 rays; anal fin with 11 rays; pectoral fin with 20-25 rays; interorbital region of the neurocranium wide; postorbital sector of the neurocranium longer than the orbital one; four ossified pectoral-fin radials; opercle with a strong pointed spine; subopercle bearing two spines and two short filaments; scales absent] that support its recognition as a new genus of the family Batrachoididae. Zappaichthys harzhauseri, gen. et sp. nov., is the oldest member of the Batrachoidiformes known to date based on articulated skeletal remains. The fossil record of batrachoidiform fishes is discussed in detail.

Of the two verified eruptions, one (Cleveland) was clearly magmatic and the other (Kanaga) was most likely a single phreatic explosion. Two other volcanoes had notable seismic swarms that probably were caused by magmatic intrusions (Iliamna and Little Sitkin). For each period of clear volcanic unrest, AVO staff increased monitoring vigilance as needed, reviewed eruptive histories of the volcanoes in question to help evaluate likely outcomes, and shared observations and interpretations with the public. 2012 also was the 100th anniversary of Alaska's Katmai-Novarupta eruption of 1912, the largest eruption on Earth in the 20th century and one of the most important volcanic eruptions in modern times. AVO marked this occasion with several public events.

The data show (a) that children in Los Angeles, whether US- or Mexican-born, are not growing up as active SLQZ speakers and (b) that given sustained travel between the two communities, language use in Los Angeles is replicated in San Lucas, thereby introducing Spanish and English into otherwise Zapotec-only domains such as the home. The case of SLQZ is one in which a language vitality assessment that considers the home community only, would lead to an incorrect evaluation. Signs of language endangerment become evident in a sociolinguistic analysis that crosses borders.

Vesuvius eruption AN - 1542640605; 2014-046436 AB - This study records that Pompeii, long before its final devastation by the 79 A.D. Vesuvius eruption in southern Italy, was damaged by several mass gravity flows. Composition of the deposits indicates that they were derived from volcaniclastic cover of carbonate highlands positioned 14 km NE of the city. Stratigraphic and petrologic analyses of sections in excavations and drill cores in and near Pompeii record the presence of three downslope-directed debris flows dated between 8th and 2nd century B.C. Some of these deposits were channelized via a stream bed that once extended from high reliefs to Pompeii. It is proposed that one of these events may have been partially responsible for urban decline during the 4th century B.C. These mass flows are interpreted as having been triggered primarily by intense rains in a manner similar to those that have occurred and destroyed towns in this region during the past 50 years. Our investigation shows that Pompeii and adjacent areas in the past, much as in recent time, have likely been most frequently susceptible to episodic damage by avalanches and mass flows of volcaniclastic material resulting from hydrological effects rather than from volcanic events, earthquake tremors, and societal disruptions such as wars.

Replenishing fuel stores at stopover sites requires adjusting to unfamiliar landscapes with little to no information about the distribution of resources. Despite their critical importance to the success of songbird migration, the effects of landscape composition and configuration on fuel deposition rates (FDR [g/d]), the currency of migration, has not been tested empirically. Our objectives were to understand the effects of heterogeneous landscapes on FDR of forest-dwelling songbirds during spring migration. Our findings provide empirical evidence for the argument that hardwood forest cover is a primary determinant of the quality of a stopover site in this region. This study represents the first effort to empirically quantify FDRs based on the configuration of landscapes.

Theoretically, coevolution predicts strong selection to maximize fitness of the parasite that minimizes costs to its host, which potentially leads to the evolution of benign interactions. We studied the demographic and behavioral traits of the ant social parasite Megalomyrmex symmetochus (Solenopsidini), an agro-predator that feeds on larvae and fungal garden products of their host, Sericomyrmex amabilis (Attini). Based on demographic data from 15 parasitized colonies, the proportion of parasitic workers to those of the host is 1:2. Moreover, defensive prophylactic behaviors observed during infections with Metarhizium brunneum, a generalist entomopathogen, and Escovopsis, a specialized fungal garden parasite, showed that S. amabilis works extensively to remove and control fungal infections, in contrast to M. symmetochus. M. symmetochus, however, performed intraspecific allogrooming during infections with Escovopsis and M. brunneum, suggesting that they may recognize fungal pathogens and indirectly limit dispersion of spores. Our results indicate that M. symmetochus did not have a strong role in maintaining a hygienic nest.

However, extremely large and variable group size and growing evidence for affiliative relationships among males, make them a fascinating subject for studies of male-male tolerance and the evolution of large groups. During a 13-month study of free ranging Guianan bearded sakis (Chiropotes sagulatus) in continuous forest in Suriname, we documented variation in group size seasonally and social behaviour, particularly among males. We found that group size was smaller and more variable in the long dry season than the short wet season, perhaps in response to changes in resource availability. We found clear evidence of affiliative male-male relationships, with males being more social than females (89.2% of events involved one male versus 15.6% that involved one female) and typically socializing with other males (68.7% of events involved 2 or more males). We also found no evidence of hierarchical relationships between males (complete absence of agonistic interactions), and we documented unique male-affiliative behaviours and temporary all-male subgroups for the first time. To investigate potential explanations of male tolerance, we compared bearded saki social patterns to other multi-male group living primates (Ateline and Pan spp.). We found similarities with Brachyteles that suggest high intergroup mating competition and scramble competition for mates within groups.

In this study, we evaluate the effectiveness of traditional linear measurements and ratios, flake scar angles, and 3D model-based flake contours for the statistical differentiation of projectile point type(s) and reduction technique. Sixty-three fluted bifaces from eastern North America and fourteen replicate Clovis points are analyzed. Discriminant analysis shows that 3D model-based Fourier descriptors of flake scar contours are less successful than traditional metrics in correctly differentiating styles, but more successful in identifying individual knappers. Changes in the symmetry of front and back flake scars between Clovis and later fluted point styles indicate a possible shift in reduction techniques. These findings demonstrate the usefulness of both traditional and modern morphometric variables to quantify biface morphology, and address questions about social interaction and technological change in Pleistocene North America.

Many of these became extinct, together with endemic insectivores, sloths, and primates, in what is widely considered an archtypical example of Quaternary extinction on oceanic islands. When and how the ancestors of these land mammals arrived on these islands is debated. Here we report on the discovery, for the first time, of undoubted rodent incisors in Oligocene contexts in Puerto Rico. The enamel microstructure of the Puerto Rican fossils is consistent with caviomorph affinities, particularly with extinct Pleistocene species from Puerto Rico and Anguilla (Lesser Antilles). These fossils represent the oldest rodents now known from the West Indies, as well as the oldest record of caviomorphs north of the Equator. Their presence in the Greater Antilles by the early Oligocene suggests that caviomorph rodents must have begun to disperse throughout South America, and beyond, very soon after their initial radiation (currently pegged to middle or late Eocene). This, together with other lines of evidence, is consistent with the landspan hypothesis for the origin of the Greater Antillean land mammal fauna, although other mechanisms, including overwater transport, cannot be ruled out.

TIMS Th-U ages of in situ corals indicate that most of the terrace is composed of reefal limestones correlating to Marine Oxygen Isotope Stage 7 (MIS 7, approximately 190-245 ka). The position of the in situ MIS 7 reef complex indicates that it formed during periods when local sea level was approximately 9 to 20 m below present sea level. Its extensiveness and geomorphic prominence as well as a paucity of emergent in situ MIS 7 reef-framework deposits on Oahu suggest that much of MIS 7 was characterized by regional sea levels below present. Later accretion along the seaward front of the terrace occurred during the latter part of MIS 5 (i.e., MIS 5a-5d, approximately 76-113 ka). The position of the late MIS 5 reefal limestones is consistent with formation during a period when local sea level was below present. The extensiveness of the submerged Pleistocene reefs around Oahu compared to the relative dearth of Holocene accretion is due to the fact that Pleistocene reefs had both more time and more accommodation space available for accretion than their Holocene counterparts.

We assessed microbial nutrient limitation by quantifying soil microbial biomass and hydrolytic enzyme activities in a long-term nutrient addition experiment in lowland tropical rain forest in central Panama. Multiple measurements were made over an annual cycle in plots that had received a decade of nitrogen, phosphorus, potassium, and micronutrient addition. Phosphorus addition increased soil microbial carbon (13 %), nitrogen (21 %), and phosphorus (49 %), decreased phosphatase activity by ~65 % and N-acetyl beta -glucosaminidase activity by 24 %, but did not affect beta -glucosidase activity. In contrast, addition of nitrogen, potassium, or micronutrients did not significantly affect microbial biomass or the activity of any enzyme. Microbial nutrients and hydrolytic enzyme activities all declined markedly in the dry season, with the change in microbial biomass equivalent to or greater than the annual nutrient flux in fine litter fall. Although multiple nutrients limit tree productivity at this site, we conclude that phosphorus limits microbial biomass in this strongly-weathered lowland tropical forest soil. This finding indicates that efforts to include enzymes in biogeochemical models must account for the disproportionate microbial investment in phosphorus acquisition in strongly-weathered soils.

AN - 1492644309; 18915665 AB - Calcium is an important nutrient for birds, especially for eggshell production and the mineralization of the skeleton of developing young. In temperate regions insects and seeds that form the bulk of the diet of breeding passerines do not contain sufficient calcium to meet the needs of breeding females and young; these birds obtain their calcium by eating snails, woodlice and millipedes. Little is known about the way tropical frugivorous passerines meet their calcium needs. The calcium contents of fruits of 34 species eaten by birds during the breeding season in mature floodplain forest in south-eastern Peru were determined. The suitability of these fruits as calcium sources for hypothetical 10-g and 25-g birds and for 26 species of frugivore that breed at the study site was evaluated based on bird body weight and on the rictal width of the bill, which influences feeding. Fruits of five species in the study area appear to be suitable sources of calcium for birds less than or equal to 25 g, although those of Ficus killipii (Moraceae) are likely optimal. The latter contain a lot of calcium (2.48% dry weight of pulp or c. 4.15 mg per pulp per fruit) and are small enough (mean diam. = 9 mm) for most birds to swallow whole, and trees produce large crops. Snails, woodlice and millipedes are common in the area and also contain sufficient calcium to meet birds' needs. In addition, birds could likely meet their calcium needs through geophagy at natural mineral licks.

We used a Bayesian mark-recapture analysis to estimate lifelong survival and lifespan of a cohort of 372 weaned pups branded in 1985-1987 and resighted until 2008. Annual survival probability of females averaged 86.3%/yr at ages 5-16, then declined until age 21, the age of the oldest female. Male survival was lower, averaging 67.7%/yr from age 1 to age 15, the age of the oldest male. Northern elephant seal females in the expanding population at Ano Nuevo live longer than southern elephant seal females (M. leonina) at colonies whose populations are declining. This comparison suggests that high survival of females is a key factor in population growth.

The increase in foliar P involved similar proportional increases in organic and inorganic P in two species and a disproportionately large increase in inorganic P in A. blackiana.Nitrogen addition did not alter foliar N concentrations in any species, but did decrease N resorption proficiency in H. concinna.A fourth species, the palm Oenocarpus mapora, demonstrated remarkably static foliar nutrient concentrations, responding only with a marginal decrease in P resorption proficiency under N plus P co-addition.Synthesis. Collectively, these results suggest that adjustment of N/P ratios can be expected in eudicots exposed to elevated P, but foliar N appears to already be at optimal levels in these lowland rain forest tree species. The complexity of species-specific responses to altered nutrient availability highlights the difficulty in predicting future responses of tropical forest trees to a changing world.

AN - 1492626055; 18957684 AB - How animals sense, process, and use magnetic information remains elusive. In insects, magnetic particles are candidates for a magnetic sensor. Recent studies suggest that the ant Pachycondyla marginata incorporates iron-containing particles from soil. We used leaf-cutter ants Atta colombica to test whether soil contact is necessary for developing a functional magnetic compass. A. colombica is the only invertebrate known to calculate a path-integrated home vector using a magnetic compass. Here, we show that A. colombica requires contact with soil to incorporate magnetic particles that can be used as a magnetic compass; yet, we also show that ants can biosynthesize magnetic particles. Workers from a soil-free colony ignored a 90 degree shift in the horizontal component of the geomagnetic field, yet oriented homeward despite the occlusion of any geocentric cues. In contrast, workers from a soil-exposed colony oriented to an intermediate direction between their true and subjective home in the shifted field. Homeward orientations under shifted fields suggest that ants calculated a path-integrated vector using proprioceptive information. Strikingly, ants from the soil-free colony also had magnetic particles; yet, as observed by ferromagnetic resonance, these particles differed from those in soil-exposed ants and were not associated with a magnetic compass sensitive to this experimental manipulation.

It has been repeatedly claimed that aggregated (stacked) SDMs (S-SDMs) will overestimate species richness. One recently suggested solution to this problem is to use macroecological models of species richness to constrain S-SDMs. Here, we examine current practice in the development of S-SDMs to identify methodological problems, provide tools to overcome these issues, and quantify the performance of correctly stacked S-SDMs alongside macroecological models. Locations Barents Sea, Europe and Dutch Wadden Sea. Methods We present formal mathematical arguments demonstrating how S-SDMs should and should not be stacked. We then compare the performance of macroecological models and correctly stacked S-SDMs on the same data to determine if the former can be used to constrain the latter. Next, we develop a maximum-likelihood approach to adjusting S-SDMs and discuss how it could potentially be used in combination with macroecological models. Finally, we use this tool to quantify how S-SDMs deviate from observed richness in four very different case studies. Results We demonstrate that stacking methods based on thresholding site-level occurrence probabilities will almost always be biased, and that these biases will tend toward systematic overprediction of richness. Next, we show that correctly stacked S-SDMs perform very similarly to macroecological models in that they both have a tendency to overpredict richness in species-poor sites and underpredict it in species-rich sites. Main conclusions Our results suggest that the perception that S-SDMs consistently overpredict richness is driven largely by incorrect stacking methods. With these biases removed, S-SDMs perform similarly to macroecological models, suggesting that combining the two model classes will not offer much improvement. However, if situations where coupling S-SDMs and macroecological models would be beneficial are subsequently identified, the tools we develop would facilitate such a synthesis.

We have measured the structural evolution and compressional behavior of different lead dioxide polymorphs up to 140 GPa in the laser-heated diamond-anvil cell using argon as a pressure medium. High-temperature heating prevents the formation of multi-phase mixtures found in a previous study conducted at room temperature using a silicone grease pressure medium. We find diffraction peaks consistent with a baddeleyite-type phase in our cold-compressed samples between 30 and 40 GPa, which was not observed in the previous measurements. Lead dioxide undergoes a phase transition to a cotunnite-type phase at 24 GPa. This phase remains stable to at least 140 GPa with a bulk modulus of 219(3) GPa for K' (sub 0) = 4. Decompression measurements show a pure cotunnite-type phase until 10.5 GPa, where the sample converts to a mixture of baddeleyite-type, pyrite-type, and OI-type (Pbca) phases. Pure alpha -structured lead dioxide (scrutinyite) is found after pressure release at room pressure even though our starting material was in the beta -structure (plattnerite). Pressure quenching to the alpha -structure appears to be a common feature of all group IVa oxides that are compressed to structures with greater density than the rutile-type structure.

Basalts examined by the Spirit Mars Exploration Rover in Gusev Crater range from the K-poor Adirondack class (0.02 wt% K (sub 2) O) to K-rich Backstay class (up to 1.2 wt% K (sub 2) O) and exhibit substantially more variation than observed in martian basaltic meteorites. The ratios of ferric to total iron (Fe (super 3+) /Fe (sub T) ) measured by the Mossbauer spectrometer are high (equivalent to -0.76 to +2.98Delta QFM; quartz-fayalite-magnetite buffer as defined by Wones and Gilbert, 1969), reflecting secondary Fe (super 3+) phases. By combining the Fe (super 3+) /Fe (sub T) of the igneous minerals (olivine, pyroxene, and magnetite) determined by Mossbauer spectrometer, we estimate primary fO (sub 2) for the Gusev basalts to be -3.6 to 0.5Delta QFM. Estimating the fO (sub 2) as a function of the dependence of the CIPW normative fayalite/magnetite ratios on Fe (super 3+) /Fe (sub T) yields a slightly smaller range of -2.58 to +0.57Delta QFM. General similarity between the fO (sub 2) estimated for the Gusev basalts and ranges in fO (sub 2) for the shergottitic meteorites (-3.8 to 0.2Delta QFM; Herd, 2003; Goodrich et al., 2003) suggests that the overall range of fO (sub 2) for the martian igneous rocks and mantle is relatively restricted. Like the shergottites (Herd, 2003), estimated fO (sub 2) of three Gusev classes (Adirondack, Barnhill and Irvine) correlates with a proxy for LREE enrichment (K (sub 2) O/TiO (sub 2) ). This suggests mixing between melts or fluids derived from reservoirs with contrasting fO (sub 2) and REE characteristics. Oxygen fugacity estimates for the martian interior suggest that tectonic processes have not led to sufficient recycling of oxidized surface material into the martian interior to entirely affect the overall oxidation state of the mantle.

Gray whales, however, also inhabited the North Atlantic Ocean until recent historical times ( approximately 1600AD), leaving open questions about their historical ecology in nearshore communities of this basin. Here we report the discovery of fossil remains from two individual gray whales recovered from underwater excavations at separate localities of JY Reef, an offshore reef situated approximately 32 kilometers (km) offshore of St. Catherine's Island, Georgia, U.S.A. Both mandibles are diagnostic to the living E. robustus. Radiometric dating of shells from JY Reef suggests an approximate age range of these two specimens between 42 and 30 thousand years before present (ka). Morphological measurements of the preserved elements indicate that both of the mandibles likely belonged to immature and possibly yearling individuals. Collectively, these findings are among the oldest occurrences of gray whales in the North Atlantic basin, and their presence at temperate latitudes provides limited support for the hypothesis that Atlantic gray whales used a southerly breeding area at the end of a migratory pathway, by analog with lagoonal breeding environments of Baja California, Mexico, for the extant California gray whales, and the breeding areas for the extant North Atlantic right whales (Eubalaena glacialis) off the Georgia coast today. Stronger support for this latter contention may stem from future fossil discoveries in the region, as well as ancillary lines of evidence, such as the remains of species-specific ectoparasites and/or ancient DNA (aDNA).

Whereas ongoing changes are closely monitored through satellite observations, we have only limited data of past Arctic sea-ice cover derived from short historical records, indirect terrestrial proxies, and low-resolution marine sediment cores. A multicentury time series from extremely long-lived annual increment-forming crustose coralline algal buildups now provides the first high-resolution in situ marine proxy for sea-ice cover. Growth and Mg/Ca ratios of these Arctic-wide occurring calcified algae are sensitive to changes in both temperature and solar radiation. Growth sharply declines with increasing sea-ice blockage of light from the benthic algal habitat. The 646-y multisite record from the Canadian Arctic indicates that during the Little Ice Age, sea ice was extensive but highly variable on subdecadal time scales and coincided with an expansion of ice-dependent Thule/Labrador Inuit sea mammal hunters in the region. The past 150 y instead have been characterized by sea ice exhibiting multidecadal variability with a long-term decline distinctly steeper than at any time since the 14th century.

Archeological and paleoecological records provide important context for understanding modern environmental and sociopolitical developments on islands. We review and analyze human interactions with island ecosystems in Polynesia, the Caribbean, and California during the last several millennia. Our analysis demonstrates that human impacts on island ecosystems and cases of highly managed anthropogenic landscapes extend deep in the past, often beginning at initial settlement. There are important issues of scale and island physical characteristics, however, that make human ecodynamics on islands variable through space and time. These data demonstrate that current environmental problems have their roots in deeper time and suggest that the Anthropocene likely began by the onset of the Holocene, if not earlier.

In this article these various proposed dates for the onset of the Anthropocene are briefly discussed, along with the data sets and standards on which they are based. An alternative approach to identifying the onset of the Anthropocene is then outlined. Rather than focusing on different markers of human environmental impact in identifying when the Anthropocene begins, this alternative approach employs Niche Construction Theory (NCT) to consider the temporal, environmental and cultural contexts for the initial development of the human behavior sets that enabled human societies to modify species and ecosystems more to their liking. The initial domestication of plants and animals, and the development of agricultural economies and landscapes are identified as marking the beginning of the Anthropocene epoch. Since this transition to food production occurred immediately following the Pleistocene-Holocene boundary, the Anthropocene can be considered as being coeval with the Holocene, resolving the contentious "golden spike" debate over whether existing standards can be satisfied for recognition of a new geological epoch.

After a long phase of neglect, study of exquisitely preserved new material of the Early Permian Cacops from Oklahoma has prompted reconsideration of other dissorophids, such as the Early Permian Conjunctio from New Mexico. Here we report on a specimen previously referred to Conjunctio from the Nocona Formation of north-central Texas. It actually represents a distinct new taxon, for which the binomen Scapanops neglecta is proposed. It represents a small dissorophid with derived characters combining to give a unique skull configuration: extremely short skull table, jaw joint situated well anterior to occiput, large orbits with wide interorbital distance, and a preorbital region more than twice as long as the postorbital region. The external nares are elongate, and the outline of the skull is ovoid, widest at mid-level of the orbits. S. neglecta shares with eucacopines the presence of a rounded internarial fenestra and an anteroposteriorly short supratemporal. Phylogenetic analysis places Scapanops at the base of the clade Eucacopinae, more crownward than Conjunctio and as the sister-taxon to a grouping comprising Cacops, Kamacops, and Zygosaurus.

Reisz; Renaissance paleontologist AN - 1828844654; 2016-087528 AB - Robert R. Reisz has published some 157 papers over 40 years, mostly on Permo-Carboniferous stegocephalians (sensu Laurin; "tetrapods" in traditional usage), especially amniotes, but also on other taxa and periods, from Devonian dipnoans to Neogene primates. He has been a leader in the study of early amniote phylogeny, publishing one of the first cladograms of these taxa in 1980. His work has proposed new hypotheses about the origin of turtles, extant amphibians and therapsids. His classical work on Paleozoic synapsids provided the basis for currently accepted taxonomies. He has also tackled several major evolutionary innovations, such as the origin of herbivory among tetrapods and the use of venom in mammals. Finally, he has proposed new calibration constraints for molecular dating. He has trained a number of postdoctoral fellows, doctoral and masters' students. Abstract Copyright (2013) Elsevier, B.V.

The mission is scheduled for launch in 2015 with arrival at Mercury in 2021. To achieve MERTIS's scientific goals the instrument maps the surface of Mercury with a spatial resolution of 500m for the spectrometer channel and 2km for the radiometer channel. MERTIS spans wavelength ranges of 7-14 and 7-40 mu m with its two channels. Among it scientific goals, MERTIS will infer rock-forming minerals, map surface composition, and study surface temperature variations on Mercury with an uncooled microbolometer detector. To exploit the full potential of the unique MERTIS dataset, an extensive calibration campaign has been performed. This includes radiometric, spectral, and geometric calibration. In addition we have performed measurement of analog materials at temperatures of up to 500 degrees C - similar to the peak temperatures expected at Mercury - with the MERTIS qualification model in the Planetary Emissivity Laboratory. These measurements allow for the evaluation of the MERTIS performance in direct comparison with the laboratory spectrometer. They also enable the creation of synthetic MERTIS datasets. For this purpose we use data from the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft as baseline. MESSENGER can provide geological information as well as spectral information in the UV, visible and near-infrared wavelengths range. For a first test we have selected the Kuiper-Rudaki region. The region has been extensively covered by measurements from the MESSENGER spacecraft. Recent analysis of observations by the Mercury Atmospheric and Surface Composition Spectrometer (MASCS) instrument on the MESSENGER spacecraft with an unsupervised hierarchical clustering method shows at global scales two major units: a Polar region (PR) spectrally flat and redder than the equatorial region (ER). The study area is primarily classified as a homogeneous expanse of the equatorial region (ER) cluster. Further clustering shows that the study area belongs to the "core" ER, in opposition to some smaller patches of a transitional sub-unit, that are transitional region between global ER and the polar region (PR) cluster. Assuming a set of several potential mineralogies for the study area and modeled surface temperature at different local times we can obtain at PEL the spectra in the mid-infrared spectral range. Combining these with our knowledge of the MERTIS performance we can produce simulated MERTIS datasets of the study region at different point of the mission.

Recently, nitrogen isotopes have been identified as a potential new proxy in these shells. delta (super 15) N content in mollusk shells is affected by numerous anthropogenic and natural influences and may be used as an environmental proxy for nitrogen loading conditions. Chesapeake Bay is well known for both historic and modern pollution problems from numerous anthropogenic sources, such as fertilizer runoff, sewage discharge, and densely populated land use and serves as an ideal study location for long-term nitrogen loading processes. Longer records of these processes may be recorded in abundant archaeological remains around the bay, however, little is known about the stability of delta (super 15) N and %N in shell material over recent geologic time. In this study, 90 archaeological C. virginica shells were collected by the Smithsonian Institution from the Rhode River Estuary within Chesapeake Bay and range in age from approximately 150 to 3200 years old. Twenty-two modern C. virginica shells were also collected from nearby beds in the bay. All shell samples were subsampled from the resilifer region of the calcitic shell using a hand-held micro drill and were analyzed using EA-IRMS analysis to determine the potential temporal variability of delta (super 15) N and %N as well as creating a baseline for ancient nitrogen conditions in the bay area. Modern POM water samples and C. virginica soft tissues were also analyzed in this study to determine the degree of seasonal variation of delta (super 15) N and %N in Chesapeake Bay.

The BCR flora is irregularly but extensively exposed along a nearly equal 4 km north-south transect and records a lowland flora that grew on a coastal delta on the western shore of the Cretaceous Interior Seaway (Meeteetse Formation). The transect spans a diverse landscape and a range of environmental gradients from very carbon-rich, swampy soils in the southern portion to less carbon-rich in the north; the landscape is also intersected by multiple inactive channel cuts that were filling with sediment and organic matter at the time of ash deposition. Recently Wing and others (2012, Ecological Monographs) described the composition of the local plant community at high resolution across the entire landscape, including identification and quantification of cover and richness for >122 taxonomic morphotypes, for each of 100 sites along the transect. Big Cedar Ridge captures an important time in the ecological development of plant communities: the site preserves ferns, gymnosperms, and angiosperms in "fern thicket" floral assemblages, which are rare today, as well as disturbed habitats with abundant herbaceous "dicot" angiosperms. During the Late Cretaceous angiosperms were globally increasing in abundance, displacing other plant groups as vegetational dominants. This setting allows for a novel analysis of plant biomarkers in the context of floral diversity, abundance, and landscape heterogeneity. We quantified leaf waxes (n-alkyl lipids), plant-derived terpenoids, bacterial hopanes, carbon isotope values (including bulk and compound-specific), and percent total organic carbon of the underlying paleosol for 36 sites along the transect in order to assess the influence of floral composition and soil environment on biomarker distributions and preservation. We compare lipid and stable isotope values with measurements of plant cover, organic carbon, and grain size in order to test biomarker variation across different facies and habitats, including evaluating primary and secondary signals. We also address how the biomarker data reflect changes in the composition of vegetation across the transect, e.g. the relationship between angiosperm cover and soil n-alkanes. We find that in spite of significant plant community heterogeneity across the transect, relative abundances of leaf wax biomarkers are relatively constant and therefore appear to faithfully reflect landscape-scale or time-averaged soil inputs rather than immediately adjacent plant types. Bulk carbon isotope values are more heterogeneous across the landscape and correlate with soil organic carbon content. This study provides important context for ecosystem-level interpretations of terrestrial paleoenvironments from biomarker proxy records.

Quantifying the relationship between carbon cycle perturbations and the hydrologic cycle in the geologic past is crucial to understanding and accurately modeling how anthropogenic carbon emissions will affect future changes in the hydrologic cycle. Records of paleohydrologic response to global warming in the geologic past are rare, particularly for continental interiors, where climate model projections of precipitation are highly uncertain. Here we examine hydrogen isotope ratios of leaf waxes as a tool for reconstructing paleohydrologic change in the continental interior of North America across the Paleocene-Eocene Thermal Maximum (PETM), an abrupt, transient episode of extreme global warming nearly equal 56 Ma. New hydrogen isotope measurements of leaf-wax n-alkanes from the southeastern Bighorn Basin, Wyoming record two positive shifts during the PETM. n-Alkane delta D values first shift to more positive values just after the onset of the carbon isotope excursion and then again higher up in the body of the carbon isotope excursion, with a return to slightly more negative delta D values in between. Paleobotanical, paleopedologic, and isotope data from the same field area have suggested that the Bighorn Basin may have experienced a drier or more seasonally dry climate during the PETM. Mean annual precipitation estimates based on paleosol major oxides, soil wetness assessed using the soil morphology index, and an aridity proxy based on differences in delta (super 18) O values of tooth enamel in aridity-sensitive and aridity-insensitive mammals each independently suggest a potential two-phase drying within the PETM interval. Similarly, the hydrogen isotope record could reflect two periods of drying, with a return to slightly wetter conditions in between. However, leaf-wax hydrogen isotope ratios reflect not only source water hydrogen isotope values but also deuterium-enrichment resulting from soil evaporation and transpiration. Interpretation of hydrogen isotope records requires consideration of both of these factors. To examine the potential roles of changes in source water isotopic composition and transpirational D-enrichment, we compare the hydrogen isotope ratios of leaf waxes with the oxygen isotope ratios of tooth enamel from Coryphodon, a large herbivore and an obligate drinker. The Coryphodon tooth enamel delta (super 18) O record enables us to constrain shifts in surface water isotope values. Relative humidity of paleoenvironments can then be explored using a modified Craig-Gordon model for transpirational D-enrichment. Preliminary calculations suggest that relative humidity increased during the PETM, contrary to the drying suggested by all other aridity proxies. One possibility is that leaf waxes record only the relative humidity at the time of leaf formation. Therefore, the n-alkane delta D record could reflect an increase in seasonality of precipitation, with greater relative humidity during the early growing season. To evaluate the validity of this approach, we will systematically examine the assumptions involved in using hydrogen isotope ratios of leaf waxes as a paleoaridity index to evaluate paleohydrologic changes in the Bighorn Basin during the PETM.

Originally hypothesized by the Iowa Geological and Water Survey though identification of a unique shale layer and shocked quartz from borehole samples, the 5.5 km diameter structure is nearly completely concealed beneath the town of Decorah, Iowa and the surrounding area. In late 2012 and early 2013, the US Geological Survey conducted airborne geophysical studies in the area to investigate structures and potential mineral resources associated with the 1.1 Ga Midcontinent Rift system. Full-tensor gravity gradiometry and airborne transient electromagnetic surveys were flown to investigate basement geometry and composition, as well as to map out the thick package of Phanerozoic sediments blanketing the region. Multiple survey lines intersected the impact structure, which was clearly visible in both the electromagnetic and gravity datasets. The electromagnetic data, acquired with a VTEM system from Geotech, Ltd., identified and mapped the post-impact Winneshiek Shale, which is present only in the crater (having been eroded everywhere else within the survey area). The resulting 5.5 km diameter circular conductor aligned nearly perfectly with the structure inferred by the Iowa Geological and Water Survey. The airborne full-tensor gravity gradient data, collected by Bell Geospace, clearly demarcates a density low in each component consistent with the center of the impact structure. The conductivity and density of some of the stratigraphic units both within as well as outside the impact structure were measured from core samples, and used to inform the modeling and inversion approaches. Both the electromagnetic data and the gravity gradiometry data underwent an extensive modeling and inversion procedure to investigate the geometry of the impact structure in three dimensions. From these results, we present a three dimensional model of the proposed Decorah Impact Structure and surrounding area. Not only will this model improve an understanding of the geology and hydrology of the region, but also will allow for more precise estimations of the energy and size of the impacting body.

Almost ten Mars years of continuous spacecraft monitoring reveals a unique planetary environment where interaction of the surface with solid and gaseous CO2 dominates current activity. The action of liquid water (dominant on Earth) is restricted to rare locations where recurring slope lineae are best explained as flow of brines. The seasonal frost cycle has been studied for decades; however, a wealth of new detail has emerged through recent spacecraft monitoring. Frost sinters into semi-transparent slabs in some locations allowing spring sunlight to penetrate to the base. Basal sublimation produces pressurized gas that jets from weak locations, scours channels in underlying terrain, erodes polar dunes and is responsible for a plethora of transient albedo features. In the mid-latitudes, CO2 frost is now thought to be the driver of mass movements within gullies both in crater walls and dunes. Many examples of mass transport from gully alcoves, through channels and onto debris aprons have been observed to occur at the coldest times when CO2 frost is present. Liquid water may have played a role in gully formation in the past, but it does not in today's activity. Other active slope processes include rock falls, dust avalanching, and perhaps other, slower processes. A small CO2 ice cap precariously persists throughout southern summer buffering atmospheric pressure. Pits litter this cap and observations over 8 Mars years have shown them to expand by several m/yr from ablation. This erosion has prompted speculation of current climate change; however, models exist where ice cap surfaces may regrow in a cyclic manner. Observations suggest that it is climatic variability associated with late-summer global dust storms that allows this regrowth. Although less volatile than CO2, water ice deposits are also changing. Steep cliffs that bound the polar layered deposits (PLD) have been observed to retreat from failure of sections up to 70m across. Avalanches on those scarps are so common in some seasons that several can be seen in progress in a single HiRISE image. New impact craters in the mid-latitudes expose sub-surface ice whose geographic extent implies that it is currently retreating, while infill of craters on the PLD confirm polar accumulation. This poleward transport of water ice is only the most recent chapter in PLD accumulation, but provides a link to this historical record. Wind is also a powerful agent of surface change. Migration of dunes and ripples is now monitored at many sites. Dark ejecta blankets of newly formed impact craters change over time as fallout of atmospheric dust gradually obscures them. Regional albedo boundaries shift episodically in response to dust storms while seasonal frost appears to reset surface albedo at high latitudes each year. The episodic nature and interannual variability of surface changes make extrapolation from short-term records perilous. Long-term monitoring increases the value of all datasets and is the means by which we can understand the nature and rates of many geologic processes on Mars today.

One of the obvious problems with age-dating valley networks is the fact that they are small, linear features that are easily destroyed by large impact craters, thus counting craters on valley networks themselves is difficult at best. We proposed a new global study dating 27 drainage basins and subbasins in Sabaea and Arabia Terrae with the basin age-dating technique. Valley networks are contained within drainage basins, which is defined as the area that contributes water to a particular channel or set of channels . For our study, we used THEMIS (Thermal Emission Imaging System) visible images with a spatial resolution of 100 m/pixel which allow us to count craters with diameter of 1 km and larger. A digital elevation model (DEM) using 1/128 gridded Mars Orbiter Laser Altimeter (MOLA) helped us to extract the 26 basins and sub-basins drainage divides From these measurements, our study shows: (1) that all the drainages basins of a large region seem to cease their main fluvial activity at the same time at the end of the Early Hesperian epoch ( approximately 3.54 Gyr); (2) that the basin technique is the most reliable technique to do global age-dating; and (3) that there is a possible correlation between the degradation rate and the elevation. Our conclusions suggest that the main fluvial activity ceased because of a global climate change. We suppose that most of valley networks on Mars we observed today formed during the Early Hesperian and post-dated the early and late Noachian topographic features.

However, these valley networks are underdeveloped relative to typical terrestrial networks, suggesting that valley incision was geologically brief or slow on Mars. Most previous studies have attributed the end of martian fluvial erosion to a monotonic decline of the atmosphere and climate around the Noachian/Hesperian transition. Identification of fluvial valleys on some younger surfaces, including Hesperian volcanoes, and the occurrence of morphologically pristine and degraded reaches in the same valley networks challenged the simplicity of this model. More recently, fluvial valleys and deposits have been recognized on a variety of Hesperian surfaces, including the plateau around Valles Marineris, certain impact craters, and the crustal dichotomy boundary scarp. The extent to which this late-stage erosion represents localized event floods or more widely distributed precipitation and runoff remains to be determined. To evaluate whether Hesperian resurfacing processes were concurrent with (and may have caused) late-stage fluvial erosion, we are identifying any geologically rare or long-lived events that occurred between significant resurfacing events and fluvial erosion of those surfaces. In a variety of locations, we have identified small primary craters that formed between local resurfacing and fluvial dissection of those surfaces, suggesting a gap in time between resurfacing and dissection. These small, otherwise fresh craters have rims or ejecta that were incised by late-stage flows. In other cases, thick stratified deposits accumulated on Hesperian surfaces, and those deposits were later dissected by running water. We also found that highland intercrater plains generally have Early to mid-Hesperian crater populations at diameters less than about 4 km. All smaller primary and secondary craters from the Noachian Period were eradicated. These observations suggest the following geomorphic history. 1) Crater degradation and intercrater resurfacing extended into the Early Hesperian Epoch, but perhaps at a declining rate relative to the Noachian Period. 2) Most of the relict valleys formed as crater degradation declined and intercrater geomorphic surfaces began to stabilize, late in the Noachian or early in the Hesperian Period. 3) Impact cratering, volcanism, tectonism, and wind continued to modify the martian surface during the Hesperian Period. Older valley networks experienced some wall retreat and infilling, forming the classic flat-floored morphology. 4) In one or more intervals during the Late Hesperian or Early Amazonian Epochs, many older valleys reactivated, and some new ones formed on Hesperian surfaces. Late-stage erosion was most effective on steep, high-relief slopes, including Late Noachian and Hesperian crater walls, as well as tectonic scarps. In ongoing work, identifying clear stratigraphic relationships between older valleys, interposed geologic features, and younger valleys is key to determining the number and relative ages of erosional events in the martian highlands.

We are in the early stages of an investigation to map the ripple orientations preserved on Martian sand dunes, in order to evaluate the recent wind flow over the dunes, and compare that wind flow pattern to the winds documented over terrestrial sand dunes. HiRISE image ESP_025645_1455 covers a sand dune field on the floor of a 20-km-diameter unnamed impact crater in the Terra Cimmeria region of the southern highlands, east of the Hellas impact basin. This image is centered at 34.23 S latitude, 138.437 E longitude with 25 cm/pixel resolution, and was taken on Jan 25 of 2012 during northern spring (Ls=57.4). Using ArcGIS, lines were drawn across three ripples perpendicular to the ripple crests, avoiding places where complex ripple patterns suggest more than one recent wind direction. The length of the lines provides a measure of ripple wavelength, and the line orientation gives azimuth (with a 180 degree absolute ambiguity). The barchan-like shape of some dunes, including occasional slip faces, suggest sand driving winds were from the southwest, although dune asymmetries indicate the wind regime likely was much more complex than a unimodal wind. Measurements of ripple orientations are being collected from dune locations across the planet, which should provide new constraints for the modeling of recent Martian winds.

We are evaluating the morphology, mineralogy, and distribution of these sedimentary deposits and associated valley systems that dissect the local Noachian bedrock to understand how they reflect source materials and record environmental and climatic conditions during their emplacement. Several craters, including secondary craters from the Holden impact event, also contain sedimentary deposits, suggesting at least some of the deposits are younger than Mid-to-Late Hesperian. All the deposits appear confined within basins, valleys or craters that are breached by valleys. The deposits typically show numerous beds with variable lithologies, suggesting multiple episodes of deposition and/or changing aqueous conditions over time. CRISM spectra extracted from the deposits typically have absorption features around 1.93 and 2.29 mu m, consistent with Fe/Mg-smectites. Several deposits within Arda Valles may have been emplaced when the system was blocked at the eastern end by topography associated with two unnamed craters. Deposition emplaced the clay-bearing layered sediments before an outlet was established, enabling drainage onto the lower-lying floor of Ladon basin and formation of an inverted channel within one of the valleys (Figure 1). All the deposits are located 0.5-2 km above clay-bearing deposits found on the Ladon basin floor, including within Ladon Valles, thereby indicating they were not associated with a lake within the basin or late-stage discharge from Ladon Valles. Instead, their sources appear to be localized and associated with the rim materials of the ancient impact structures or nearby weathered bedrock. The upland deposits may have formed concurrently with deposits found to the south in Eberswalde and Holden craters, indicating precipitation and/or snow melt across much of Margaritifer Terra during the Late Hesperian to Early Amazonian.

South China Sea (SCS) provides the best marine platform to investigate a number of paleoclimate and paleoceanographic problems on different timescales mainly because of high sedimentation rates, good preservation of microfossils and the location of SCS as a connector between the Western Pacific Warm Pool and the SE Asian monsoon. Here we investigate magnetic, geochemical and isotopic records from a piston core MD97-2142 rose from the southeastern SCS to understand the past glacial terminations, chemical weathering and carbon burial on orbital to millennial timescales for the last 800 kyr. Terrigenous content and Al/Ti ratio reveal higher terrigenous input during glacial periods and vice versa during interglacials. Proxies of chemical weathering reveal larger fluctuations between 150 and 500 kyr than that of the last 150 kyr. Records of C/N ratio and carbon isotope of total organic carbon (delta 13CTOC) mimic each other with higher marine productivity during marine isotope stages (MIS) 8, 10 and 12. Enrichment factors of Mn and Mo (EF Mn and EF Mo) show roughly an opposite pattern with 1 in most odd MIS, whereas < approximately 1 EF Mn was evident in even MIS, suggesting that the former condition was likely attributed to bottom water ventilation associated with high sea levels during interglacials. We found through two endmember mixing model of delta 13CTOC that lower burial of terrigenous fraction of TOC (OCTERR) during glacial intervals (MIS 6, 8, 10 and 12), but vice versa during interglacial (MIS 7, 9 and 11) periods. Our bulk magnetic susceptibility (MS) time series documents the last seven glacial terminations (T1-T7) with distinctive behaviors of T4 and T6. Wavelet analysis of MS record exhibits statistically significant periodicity at 239 kyr, 142 kyr, 85 kyr, 45 kyr, 24 kyr and 13 kyr of eccentricity, obliquity and precession cycles. With the help of diverse proxy records, the role of insolation, monsoon forcing and sea level on the variation of productivity, terrigenous input and carbon burial will be discussed on orbital and millennial timescales.

Gibbs has been observed by the Pan-STARRS 1 (PS1) sky survey from 2010 to 2012, and reveals that P/2011 S1 (Gibbs) remained active from 2010 to 2012 and has a small nucleus < 4 km radius with colors g - r = 0.5+ or -0.02, r-i = 0.12+ or -0.02 and i -z = 0.46+ or -0.03. A model dependent mass-loss rate approximately 100 kg/s was found. The mass-loss rate per unit surface area of P/2011 S1(Gibbs) is as high as that of 29P/Schwassmann- Wachmann 1, making it one of the most active Centaurs. The mass-loss rate also varies with time from approximately 40 kg/s to 150 kg/s. Due to its rather circular orbit, we propose that it has 29P/Schwassmann-Wachmann 1-like outbursts that control the outgassing rate. The results indicate that it may have similar surface composition to 29P/Schwassmann-Wachmann 1. Our numerical simulations show that the future orbital evolution of P/2011 S1 (Gibbs) is more closer to the main population of Centaurs than to 29P/Schwassmann-Wachmann 1. The result also demonstrates that P/2011 S1 (Gibbs) is dynamically unstable and can only remain near its current orbit for about thousand years. Finally, we conclude that P/2011 S1(Gibbs) has a normal Centaur-type orbit but unusually high mass-loss rate.

Modern coral reef communities in the Caribbean are being threatened by anthropogenic input of nutrients whereas one to two million years ago, communities in this same region experienced dramatic overturn of corals and mollusks with the uplift of the Central American Isthmus and subsequent reduction of upwelling-derived nutrients. Thus the ability to record past and present nutrient delivery is paramount for understanding the role of environmental change in controlling past and future biodiversity. To test trace element chemistries in gastropod shells as nutrient proxies, we measured the trace element (Mg, Sr, Ba, Mn, Fe, P, and U ) and stable isotopic (delta (super 18) O, delta (super 13) C) compositions of 11 modern Conus specimens collected from upwelling and non-upwelling regions in the Caribbean and Pacific coasts of Panama. Four Caribbean shells represent non-upwelling conditions, while seven Pacific shells record conditions of seasonal upwelling (Gulf of Panama) or shoaling of the thermocline (Gulf of Chiriqui). Shells were serially sampled around the spire at 2-3 mm intervals, providing roughly monthly resolution. Shallow-dwelling Pacific specimens show large seasonal range in delta (super 18) O (>2 ppm) reflecting upwelling during the dry season and freshening during the rainy season. In contrast, shallow-dwelling Caribbean specimens show small delta (super 18) O range (mostly < or =1 ppm) indicating limited seasonal upwelling and freshening. For trace element analyses, about 100 mu g of carbonate powder was dissolved in 2 ml of 2% HNO (sub 3) and analyzed on a high resolution, inductively-coupled plasma mass spectrometer (HR-ICP-MS). Among the wide array of trace elements analyzed, only Sr/Ca shows a significant correlation with upwelling intervals, as indicated by high delta (super 18) O. This reflects the positive relationship between Sr/Ca and temperature in Conus shells (Sosdian et al., 2006, G3, Q11023, doi:10.1029/2005GC001233). However, high Sr/Ca values are associated with delta (super 18) O minima, suggesting that Sr/Ca may also correlate inversely with salinity. Trace element/Ca ratios for Mg, Ba, Mn, Fe, P, and U show no consistent relationship with delta (super 18) O or delta (super 13) C. On the other hand, P/Ca ratios in modern Conus shells correlate with general trends in seawater phosphate, with generally higher values in the Pacific relative to the Caribbean. Preliminary results with fossils specimens are also encouraging. Whereas modern southwest Caribbean specimens show low P/Ca and delta (super 18) O range consistent with an oligotrophic environment with minimal upwelling and freshwater input, Plio-Pleistocene SWC specimens show higher P/Ca and delta (super 18) O range, arguing for greater nutrient delivery. Pacific samples show the opposite trend, greater nutrient availability in the modern environment than in the Plio-Pleistocene. These results, while preliminary, show the potential of P/Ca analyses in characterizing the nutrient status of Plio-Pleistocene oceans.

Data from amphibole, plagioclase and Fe-Ti oxides, in conjunction with quartz chemistry and cathodoluminescence (CL) imaging, reveal the following pre-eruptive conditions: temperature (650 - 850 degrees C), pressure (<200 MPa), and H (sub 2) O content (4 - 6 wt%). Preliminary results from CL zoning show that cores and rims of quartz phenocrysts erupted in the Tara supereruption exhibit a distinct difference in CL emission intensity, with bright rims encompassing rounded, resorbed, and darker cores. Bright rims contain, on average, nearly equal 60 ppm Ti whereas dark cores contain nearly equal 30 ppm Ti. Calculating TiO (sub 2) activity using oxide pairs allows us to apply the TitaniQ thermometer to our samples. The rimward increase of Ti content suggests that the crystals record heating of the Tara magma from nearly equal 650 degrees C to 750 degrees C. The sharp discontinuity between high-Ti (bright-CL) rims and low-Ti (dark) cores, the presence of resorbed, rounded cores, as well as the absence of oscillatory zoning are suggestive of a single recharge event immediately prior to eruption. Based on Ti diffusion in quartz, we estimate that this recharge event occurred within <30,000 years of eruption and may signal the timescale of the thermal stimulation of the system leading to eruption.

With high resolution SLR and video cameras, coupled with strong zoom lenses, we are able to survey motions of this surface at time scales of seconds, minutes, hours, and days. Particle image velocimetry (PIV) is used to quantify motions over the 150-200 m diameter vent region plateau. With video cameras we have observed motions at rapid time scales corresponding to the onset of explosive eruptions, which occur every few hours. For these events the nearly equal 30,000 m2 block lava surface temporarily uplifts by as much as 1 m during time scales of about a second. This rapid acceleration is thought to be the source of an equivalent downward force that produces a long period seismic signal. At longer time scales, time lapse camera imagery is used to measure bulging and subsidence of the lava surface. Transient uplift of the central part of the vent plateau is as great as 10 m and occurs over time scales of 15 to 30 minutes. Bulge formation is associated with heightened effusion and subsequent subsidence allows us an estimate of the andesitic/dacitic lava's viscosity. At even longer time scales PIV allows us to track flow of the viscous lava flow and compare observations made in subsequent years. Maximum velocities of about 10 m/day were observed in 2007 and 2009, which was far less than the 50 m/day surface movements detected in 2012 when lava flow effusion was greatly increased. These longer time scale vector flow fields provide important constraints on the relative thicknesses of lava flowing on the dome's surface.

The pink color is restricted to micrometer-thick lamellae or bands oriented along , which are created by plastic deformation, during a post growth event. Studies showed that plastic deformation is accommodated by twinning (e.g. Mineeva et al., 2009; Gaillou et al., 2010). The aim of this study is to better understand the physics and rheology of diamonds in Earth's mantle conditions. For that purpose, we used high spatial resolution Fourier Transform Infrared spectroscopy (FTIR) and Raman spectroscopy which gave us information about the repartition of the defects and of the remaining strain in the diamond structure, respectively. All diamonds are type Ia diamonds, with different amount of nitrogen and hydrogen. FTIR mapping mainly showed zoning of nitrogen defects following growth sectors, when compared to cathodoluminescence (CL) images. When present, the amber center is localized in the thin (about 1mu m) pink lamellae. Raman spectroscopy shows that the pink lamellae are defective zones, with presence of unknown photoluminescent (PL) defects. Raman mapping revealed that the strain is mostly localized at the pink lamellae (Fig. 1). The highest amount of strain recorded was 3 GPa over 1mu m (Fig.1). At the intersection of two pink lamellae, the strain is so intense that the diamond Raman band displays 4 lines, indicating at least two highly stressed regions in the probed volume, which is the first time such a phenomenon is reported in a natural sample. Natural diamond shows that it can accommodate a large amount of stress during plastic deformation in mantle conditions by mechanical twinning. Still, large amount of strain remains in the diamond structure, which does not seem to affect the diamond integrity. Plastic deformation creates new PL (and CL) centers and most likely also the center responsible for the pink color, which is still unidentified.

AN - 1686059381; 2015-050565 AB - The Fall of 2013 marks the opening of Q?rius ("curious"), a 10,000 square foot, interactive educational space at the Smithsonian Institution's National Museum of Natural History. Representing the 7 areas of the museum's research divisions, Q?rius includes a publicly accessible collection of over 6,000 natural history objects and multiple opportunities for visitors to engage themselves in natural history and the research conducted at the museum in various settings, including a lab, theater, and studio. A digital component to the space allows visitors to save parts of their experiences to a personal account, which they can later access remotely from their home or school. The space also serves as a tool for scientists to conduct outreach programs for museum visitors and for schools across the country through distance learning capabilities. Geology content for Q?rius was developed through collaboration between the Office of Education and Outreach and the Department of Mineral Sciences, as well as scientists and educators from outside agencies. Current experiences for the public include modeling plate tectonics and how they change rocks on small and large scales, identifying minerals in rocks, and using Earth to understand Martian geology. A school program adds the concept of drill cores and natural resources to the plate tectonics activity, which allows discussion about resource extraction. Developing experiences for Q?rius in all content areas took place over 2 phases; first, through taking prototypes into the museum exhibition halls to test with visitors through several iterations, and second in the new space, where all of the activities could be tested as a group and in the appropriate environment. By the time this abstract has been submitted, the official opening will not have occurred, though Q?rius will have been open for about 1 month by the time of the 2013 AGU annual conference, allowing us to further evaluate the development of the space.

Carbonate will drive flux melting; reduced carbon will not. The extent to which carbon actually works to melt the deep asthenospheric mantle, however, remains unknown. Likewise, while xenoliths from the continental mantle record decreasing fO2 with depth, the extension of this profile to the oceanic upper mantle remains speculative. Assuming that the continental xenolith record broadly mirrors the fO2 of the oceanic upper mantle, then as mantle ascends, fO2 increases and at some depth conditions become oxidizing enough to cause oxidation of carbon and concomitant reduction of iron [Stagno et al., Nature, 2013; Cottrell and Kelley, Science, 2013]. At the same time, Fe3+/Sigma Fe ratios and fO2 of erupted MORB negatively correlate with proxies for mantle source enrichment [Cottrell and Kelley, Science, 2013], suggesting that regional variations in the oxidation state of the upper mantle are tied to composition. If both the Fe3+/Sigma Fe ratio and carbon concentration vary regionally in the oceanic upper mantle as a function of its composition, then the interplay between Fe3+/Sigma Fe ratio, carbon concentration, and fO2 have key implications for the depth and extent of melting beneath mid-ocean ridges. Properties of the asthenosphere presumed to be sensitive to the presence of low degree carbonatitic or kimberlitic melt, such as shear wave velocity and conductivity, should therefore inform our understanding of the mantle's redox, carbon, and melt budgets, and vice versa. Here, we present a global assessment of the linked chemical and physical properties of the oceanic asthenosphere.

Peridotite, eclogite, and pyroxenite are candidate source lithologies for oceanic basalts; however, techniques for discriminating among them remain underdeveloped. Concentrations and ratios of several first-row transition elements (FRTE) plus Ga and Ge in basalts show promise because their bulk partition coefficients are sensitive to differences in the modal mineralogy of the solid residue. While partition coefficients for many of these elements have been determined experimentally [Le Roux11; Davis13], their application to natural systems remains limited due to a dearth of FRTE+Ga+Ge determinations for natural peridotites. The limited data that do exist imply that several oceanic islands (e.g., Hawaii; Cape Verde; Society Islands) have transition element signatures (e.g., high Fe/Mn and Zn/Fe) that are inconsistent with a strictly peridotitic source lithology. The imperative, then, is to quantify global FRTE+Ga+Ge variability in potential OIB source lithologies. We investigate the variation in FRTE, Ga, and Ge abundances and ratios in olivine, orthopyroxene, clinopyroxene, and spinel from 17 spinel lherzolite xenoliths from Ko'olau Hawaii using LA-ICP-MS. While these garnet-free rocks are not likely candidate source lithologies of Hawaiian basalts, quantifying their trace element budgets assists in the assessment of the FRTE+Ga+Ge systematics in oceanic mantle lithologies. Olivine forsterite content (Fo (sub 81) -Fo (sub 91) ) and spinel Cr# (0.02-0.41) of the xenoliths document a broad range of compositions. Low forsterite contents in several of these lherzolites suggest enrichment through melt-rock reaction during their residence in the lithosphere. Key indicator ratios vary systematically, though not always as predicted. For example, olivine forsterite content is negatively correlated with Fe/Mn ratios of all mineral phases, despite experimental evidence that bulk exchange of Fe and Mn between peridotite and melt is near unity. Mineral Zn/Fe ratios, which are expected to be elevated in partial melts relative to source peridotite, show no significant correlation with indices of enrichment. While increasing olivine Ni concentrations and Ni/Co ratios with forsterite content are consistent with expectations, Ni concentration and Ni/Co are greater than has been previously observed and span a range similar to olivine phenocrysts from OIB thought to have been derived from non-peridotitic sources [Sobolev07]. These data highlight the importance of the knowledge gap that exists in our understanding of FRTE+Ga+Ge systematics in the mantle, but also their potential to provide insight into basalt petrogenesis and the generation of lithological heterogeneities in the mantle.

Recent experimental studies show that some compositions (including pyrolitic) produce a wide mixed phase region of perovskite and post-perovskite stability equivalent to several hundred kilometers depth. The wide mixed phase region is inconsistent with a sharp seismic discontinuity. We have made in-situ high-pressure high-temperature X-ray diffraction measurements to determine the thickness of the perovskite-post-perovskite mixed phase region using water-saturated aluminous enstatite starting compositions. Enstatite with 8.5 and 1.0 wt% alumina were synthesized in the piston cylinder under water-saturated conditions and contain 1500 and 350 ppm water, respectively. Initial water concentration were calculated from infrared absorption measurements. We find that the mixed phase region is significantly reduced (<5 GPa or <100 km in thickness) for these nominally anhydrous compositions. The mechanism by which the mixed phase region is reduced is not well-constrained, but is either due to an increase of water solubility in post-perovskite structure compared to the perovskite structure or due to a lowering of the kinetic barrier to synthesized the post-perovskite phase. In either case the intentional addition of hydrogen into the silicate system appears to resolves the discrepency between experimental and seismic observations.

Within the Chiriqui gulf in western Panama, we have accomplished field mapping of Parida Island which exceptionally exposed a full series of olivine-pyroxene basaltic pillow, massive and blocky lavas, that intrude and covered a basal sequence of red cherts and mudstones followed by Miocene calcareous ooze. The lower chert sequence is affected by folding that not affected the calcareous or the volcanic rocks, whereas all the stratigraphic units are cut by normal faults which are almost paralell to the trench. Published geochemical data from the island (3) have suggest a Tholeitic transitional trend which have been related to the Galapagos hot spot track that modified the Cocos plate. From its geographic and geological characteristics we suggested that the Parida Island is an accreted remnant of the Cocos ridges accreted after the Miocene to the margin as a relatively coherent piece. Accretion was done along a detachment or peeling level located in the lower chert segment. The systematic normal faults may be either a preserved record of the bending of the oceanic plate during subduction or the consequence of the modern subduction erosion dynamics on the central American fore-arc (4).

This system is designed to produce the higher quality data required to establish and maintain the Terrestrial Reference Frame and provide information essential for fully realizing the measurement potential of the current and future generation of Earth Observing spacecraft. The prototype core site is at NASA's Geophysical and Astronomical Observatory at Goddard Space Flight Center and includes co-located, state of-the-art, systems from all four space geodetic observing techniques: Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Global Navigation Satellite Systems (GNSS), and Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS). A system for monitoring of the "ties" between these four systems is an integral part of the core site development concept and this specific prototype. When fully implemented, this upgraded global network will benefit in addition to the ITRF, all other network products (e.g. Precision Orbit Determination, local & regional deformation, astrometry, etc.), which will also be improved by at least an order of magnitude, with concomitant benefits to the supported and tracked missions, science projects, and engineering applications. We present the results of the prototype site demonstration and describe the NASA plans for implementing its next generation network.

However, fungi have been observed to produce Mn(III/IV) oxides resembling buserite, birnessite, and todorokite on the periphery of vegetative hyphae, hyphal branching points and at the base of fruiting bodies. Recent studies indicate that some of these oxides may be generated by a two-stage reaction with soluble Mn(II) and biogenic reactive oxygen species for some groups of fungi, in particular the Ascomycota. These oxides can provide a versatile protective barrier or aid in the capture of trace metals in the environment, although the exact evolutionary function and trigger is unclear. In this study, two caves in the southern Appalachians, a pristine cave and an anthropogenically impacted cave, were compared by analyzing fungal community assemblages in manganese oxide rich deposits. Quantitative PCR data indicated that fungi are present in a low abundance (<1%) in all locations sampled within the caves. Among amplified DNA sequences retrieved in an 18S rDNA clone library, over 88% were representative of the phylum Basidiomycota (predominantly Agaricomycetes), 2.74% of Ascomycota, 2.28% of Blastocladiomycota and Chytridiomycota, 0.46% of Zygomycota, and 3.65% of Eukarya or Fungi incertae sedis. Using Illumina's MiSeq to sequence amplicons of the fungal ITS1 gene has yielded roughly 100,000-200,000 paired-end reads per sample. These data are currently being analyzed to compare fungal communities before and after induced Mn oxidation in the field. In addition, sites within the pristine cave are being compared with analogous sites in the impacted cave. Culturing efforts have thus far yielded Mn oxide producing members of the orders Glomerales and Pleosporales as well as two Genus incertae sedis (Fungal sp. YECT1, and Fungal sp. YECT3, growing on discarded electrical tape) that do not appear to be closely related to any other known Mn oxidizing fungi.

These collisions take place over a time interval of about 100 million years, during which time it takes at least 10 collisions between planets to make a Venus or an Earth. In the aftermath of one of these collisions the surviving planet is hot, and can remain hot for millions of years. During this phase of accretion, the proto-terrestrial planet may have a dense steam atmosphere, that will affect both the cooling of the planet and our ability to detect it. Here we explore the atmospheric chemistry, photochemistry, and spectral signatures of post-giant-impact terrestrial planets enveloped by thick atmospheres consisting of vaporized rock material. The atmospheric chemistry is computed self-consistently for atmospheres in equilibrium with hot surfaces, with compositions reflecting either the bulk silicate Earth (BSE, which includes the crust, mantle, atmosphere and oceans) or Earth's continental crust (CC). These two cases allow us to examine differences in atmospheres formed by outgassing of silica-rich (felsic) rocks - like the Earth's continental crust - and MgO- and FeO-rich (mafic) rocks - like the BSE. Studies of detrital zircons from Jack Hills, Australia, show that the continental crust existed 164 million years after the formation of the solar system, in which case the material vaporized in a giant impact should likely reflect the CC composition. However, if at the time of impact the surface of the planet does not yet exhibit the formation of continents, then the BSE case becomes relevant. We compute atmospheric profiles for surface temperatures ranging from 1000 to 2200 K, surface pressures of 10 and 100 bar, and surface gravities of 10 and 30 m/s (super 2) . We account for all major molecular and atomic opacity sources, including collision-induced absorption, to derive the atmospheric structure and compute the reflected and emergent flux. We find that these atmospheres are dominated by H (sub 2) O and CO (sub 2) , while the formation of CH (sub 4) , and NH (sub 3) is quenched due to short dynamical timescales. Other important constituents are HF, HCl, NaCl, and SO (sub 2) . These are apparent in the emerging spectra, and can be indicative that an impact has occurred. Estimates including photochemistry and vertical mixing show that these atmospheres are enhanced in sulfur-bearing species, particularly SO (sub 2) , one of the most important absorbers. At this stage we do not address cloud formation and aerosol opacity. Estimated luminosities for post-impact planets, although lower than predicted by previous models, show that the hottest post-giant-impact planets will be detectable with the planned 30 m-class telescopes. Finally, we use the models to describe the cooling of a post-impact terrestrial planet and briefly investigate its time evolution, which ends as the planet transitions into a more conventional steam atmosphere runaway greenhouse. This calculation brings a significant improvement over previous runaway greenhouse models, by including additional opacity sources and comprehensive line lists for H (sub 2) O and CO (sub 2) . We find that the cooling timescale for post-giant impact Earths ranges between about 10 (super 5) and 10 (super 6) years, where the slower cooling is associated with the planet going through a runaway greenhouse stage.

It is unusual among subduction zones in that forearc peridotites, thought to be pieces of lithospheric mantle originating from the overriding plate, have been dredged from the trench. These spinel peridotites appear in dredges along almost 1000 km of the trench's length, from near the Samoa hotspot in the north to the Louisville seamounts in the south, and have been dredged from 4-9 km depth. The samples are very depleted, consisting entirely of dunites and harzburgites, with no observed lherzolites. Low modal abundances of orthopyroxene and high spinel Cr# (Cr/(Cr+Al)) also indicate large degrees of melt extraction. While some samples have been variably altered by hydrothermal processes, a large fraction of them are remarkably unaltered, making them ideal targets for geochemical investigation. Oxygen fugacity is an important geochemical control on phase stability, the composition of volatiles, and the position of the mantle solidus, thus rendering it critical to the understanding of mantle processes. Previous studies have suggested that subduction zone processes result in arc magmas with increased oxygen fugacity (fO (sub 2) ) relative to ridge magmas [2], but few direct observations of mantle wedge fO (sub 2) are available. In order to investigate the oxygen fugacity of the Tonga peridotites, mineral major element compositions were determined via electron microprobe. Fe (super 3+) /Sigma Fe ratios were calculated for the spinel phase, calibrated with spinel standards of known Fe (super 3+) /Sigma Fe ratio provided by B.J. Wood to the Smithsonian following the procedure of Lopez et al [3]. Oxygen fugacity was calculated according to the olivine-orthopyroxene-spinel oxybarometer method of Wood et al. [4]. Results from five dredges along approximately 600 km of trench showed oxygen fugacity values of 1 log unit above the QFM buffer, compared to the global ridge peridotite average of QFM -1. A sixth dredge from the middle of the sample area showed significantly more reduced values of QFM -2. Interactions with oxidized fluids in the mantle wedge have been proposed as a mechanism for oxidizing forearc peridotites relative to ridge peridotites. The additional observation of small length-scale variations in fO2 suggests that the interaction of fluids with the mantle is not a pervasive process, leading to the observed heterogeneity in oxygen fugacity values.

Experiments were run in a sealed, air-filled tank measuring 8.5 m long by 6.1 m wide by 2.6 m tall. Currents were generated by feeding mixture of heated particles (5 mu m aluminum oxide, 25 mu m talc, 27 mu m walnut shell, 76 mu m glass beads) down a chute at controlled rates to produce dilute, turbulent gravity currents. Comparison of experimental currents with natural PDCs shows good agreement between Froude, densimetric and thermal Richardson, and particle Stokes and settling numbers; experimental currents have lower Reynolds numbers than natural PDCs, but are fully turbulent. Currents were illuminated with 3 orthogonal laser sheets (650, 532, and 450 nm wavelengths) and recorded with an array of HD video cameras and a high speed camera (up to 3000 fps). Deposits were mapped using a grid of sedimentation traps. We observe distinct differences between ambient temperature and warm currents: * warm currents have shorter run out distances, narrow map view distributions of currents and deposits, thicken with distance from the source, and lift off to form coignimbrite plumes; * ambient temperature currents typically travel farther, spread out radially, do not thicken greatly with transport distance, and do not form coignimbrite plumes. Long duration currents (600 s compared to 30-100 s) oscillate laterally with time (e.g. transport to the right, then the left, and back); this oscillation happens prior to any interaction with the tank walls. Isopach maps of the deposits show predictable trends in sedimentation versus distance in response to eruption parameters (eruption rate, duration, temperature, and initial current mass), but all sedimentation curves can be fit with 2nd order polynomials (R2>.9). Proximal sedimentation is similar in comparable warm and ambient temperature currents, but distal sedimentation (beyond the current runout) increases in warm currents reflecting deposition from coignimbrite plumes. We are currently developing analytical models to link the observed transport and sedimentation results.

Local coastal communities have been utilizing this resource for many years. The rounded and buffered morphology of hand specimens is consistent with water-borne transit. The volcanically active Caribbean and Central American regions provide a number of candidates for source volcanoes and eruptions. We have attempted to identify this source using samples collected from Carrie Bow Cay and Placencia Beach, Belize; Tulum Beach, Mexico; Morrosquillo Bay, Colombia; and Galeta Point, Panama. We have tracked possible transport routes through the use of river drainage and ocean current maps. The criteria for comparing the products of potential source volcanoes (including Atitlan Caldera in Guatemala and Caribbean sources such as Mt. Pelee, Martinique and Soufriere Hills, Montserrat) were developed from the whole rock major and trace element geochemistry and the compositional and textural characteristics of pumice and their constituent minerals and glasses.

The pumice (LQ13-01, collected at the same location as LC84-417 (69.58 wt. % SiO2) by Clynne) is from the lower pyroclastic flow member of the group 1 lavas, the most silicic products known of Chaos Crags. Group 1 lavas are homogeneous (69-70 wt. % SiO2), petrographically and compositionally similar with rare to sparse mafic inclusions, and comprise the earliest emplaced units of Chaos Crags, the lower, middle, and upper pyroclastic flows, and domes A and B, whereas group 2 are comparatively heterogeneous (67-69 wt. % SiO2), with increasing abundance (10-15%) of mafic inclusions throughout the emplacement sequence, and comprise domes C through F. The phase assemblage in the natural sample used as experimental starting material comprises phenocrysts of quartz, plagioclase feldspars with rims of approximately An35, biotite, hornblende, and Fe-Ti oxides in a vesiculated glassy matrix. Trace mafic enclaves are also present, but were removed from experimental starting material. All experiments were performed at the Smithsonian Institution. Experiments were run under H2O-saturated conditions at pressures of 75 MPa to 200 MPa and temperatures of 750 degrees C to 900 degrees C, at oxygen fugacity NNO+1 (+ or -0.5-log-units), for 93 to 132 hours. EPMA and SEM analyses of experimental products show quartz is stable from 800 degrees C, within the investigated range. Amphibole is stable from >75 MPa at 750 degrees C to >100 MPa at 800 degrees C to 200 MPa at or =850 degrees C. Biotite is stable at or =850 degrees C. Pyroxene, not present in the starting material is stable for 200 MPa at >775 degrees C and all pressures at temperatures > or =825 degrees C, within the investigated range. FTIR analysis of quartz-hosted melt inclusions contain 4.0-5.0 wt. % H2O (average 4.3 wt. %), suggesting saturation pressures of 100-110 MPa (calculated using model of Papale et al., 2006). Comparison of the natural samples with the experimentally determined phase diagram and melt inclusions, suggests pre-eruptive storage conditions of 110-125 MPa and 775 degrees C; given FeTi-oxide temperatures of 850 degrees C, magma may have been heated by as much as 75-100 degrees C immediately prior to eruption. Ongoing work includes EPMA analysis of plagioclase feldspars and amphiboles to further constrain An-stability and hornblende-cummingtonite relations , respectively, and analysis of titanomagnetite-ilmenite pairs. Continuous decompression experiments are underway with rates ranging from 0.3 MPa/hr to 7.5 MPa/hr, corresponding to total decompression times of 16 hours to 18 days.

The algorithm is based on direct fitting of radiances from 319.0-347.5 nm, within the UV-2 channel of OMI. Radiances are modeled from the solar irradiance attenuated by contributions from the target gas and interfering gases, rotational Raman scattering, additive and multiplicative closure polynomials and a common mode spectrum. The common mode spectra (one per cross-track position, computed on-line) are the average of several hundred fitting residuals. They include any instrument effects that are unrelated to molecular scattering and absorption cross sections. The BrO retrieval uses albedo- and wavelength-dependent air mass factors (AMFs), which have been pre-computed using climatological BrO profiles. The wavelength-dependent AMF is applied pre-fit to the BrO cross-sections so that vertical column densities are retrieved directly. We validate OMI BrO with ground-based measurements from three stations (Harestua, Lauder, and Barrow) and with chemical transport model simulations. We analyze the global distribution and seasonal variation of BrO and investigate BrO emissions from volcanoes and salt lakes.

AN - 1645572362; 2015-006311 AB - Our understanding of submarine volcanism is in its infancy with respect to subaerial eruption processes. Two fundamental differences between eruptions in seawater compared to those on land are that (1) eruptions occur at higher confining pressures, and (2) in a seawater medium, which has a higher heat capacity, density and viscosity than air. Together with JAMSTEC collaborators we have a sample suite of submarine pumice deposits from modern volcanoes of known eruption depths. This sample suite spans a spectrum of eruption intensities, from 1) powerful explosive caldera-forming (Myojin Knoll caldera); to 2) weakly explosive cone building (pre-caldera Myojin Knoll pumice and Kurose-Nishi pumice); to 3) volatile-driven effusive dome spalling (Sumisu knoll A); to 4) passive dome effusion (Sumisu knoll B and C). This sample suite has exceptional potential, not simply because the samples have been taken from well-constrained, sources but because they have similar high silica contents, are unaltered and their phenocrysts contain melt inclusions. Microtextural quantitative analysis has revealed that (i) clast vesicularities remain high (69-90 vol.%) regardless of confining pressure, mass eruption rate or eruption style , (ii) vesicle number densities scale with inferred eruption rate, and (iii) darcian and inertial permeabilities of submarine effusive and explosive pyroclasts overlap with explosively-erupted subaerial pyroclasts.

Measurements from dedicated instruments aboard satellites may complement and enhance the spatially and temporally limited information from ground-based volcanic gas measurements. However, space-based detection and quantification of volcanic CO (sub 2) is challenging (e.g. because of the high atmospheric CO (sub 2) background) and has to our knowledge not been reported yet. In this study, we present direct detection and quantification of CO (sub 2) in the gas plume following the eruption of Kasatochi (Aleutian Islands, USA) on 7 August 2008 from satellite measurements from the SCIAMACHY (SCanning Imaging Absorption SpectroMeter for Atmospheric CHartographY) sensor. The analysis is based on two different SCIAMACHY CO (sub 2) products: the Weighting Function Modified Differential Optical Absorption Spectroscopy (WFM-DOAS) and the Bremen Optimal Estimation DOAS (BESD). Our strategy is to apply a threshold on SCIAMACHY retrieved sulfur dioxide (SO (sub 2) ) to distinguish between volcanic plume and background pixels. The dry-air column averaged mole fractions of CO (sub 2) of the plume pixels exceed those of the background pixels statistically significantly for the two different SCIAMACHY CO (sub 2) products analyzed. In addition, significant correlations between SO (sub 2) and CO (sub 2) are found in the plume pixels, and increasing CO (sub 2) :SO (sub 2) ratios with time show the relatively faster decay of SO (sub 2) in the atmosphere. This is used to extrapolate a CO (sub 2) :SO (sub 2) ratio at the time of the eruption which can then be used to estimate the total CO (sub 2) release. We found a relatively high CO (sub 2) mass emission from Kasatochi between 12 Tg and 57 Tg for BESD and WFM-DOAS using previously reported SO (sub 2) releases between 1.2 and 2.2 Tg, respectively, although the uncertainty range for both CO (sub 2) estimates is large. In conclusion, this study demonstrates that current space-borne remote sensing instruments can detect a volcanic CO (sub 2) signal of relatively large eruptions, and the Kasatochi eruption in August 2008 likely released a large amount of CO (sub 2) . This work implies that CO (sub 2) emissions from explosive volcanism are likely larger than previously thought.

Although 2013 marks the 50th anniversary of this canonical eruption, many specific aspects of Surtseyan eruption dynamics, and magma-water interaction in general, remain only qualitatively described. For example, eruptions or phases thereof are often referred to as "phreatomagmatic", without any discussion or identification of specific geometries and interactive volumes of the magma-water interaction involved. Moving toward a more quantitative understanding requires that all types of information: observational, textural, geochemical, and thermodynamic, be combined to effectively normalize the heterogeneity that is inherent to wet eruptions, and to yield specific descriptors of how magma and water (+/- solid contaminants) interact in style-defining ways. We explore the hypothesis that Surtseyan dynamics result from mingling between actively degassing and vesiculating magma, and slurries of previously erupted material in a flooded vent. Magmatic textures and properties can be explained by co-tracking: volatiles in phenocryst-hosted melt inclusions, the composition of gases emitted during the eruption, and evolution of magma porosity/permeability. Mingling of magma with water-saturated slurry can be identified in the textures of compound clasts over a range of grain sizes. Depending on key mingling parameters, including: the magma's porosity/permeability, the magma-slurry mixing ratio, and the slurry's particle-water mass ratio, several characteristic features of Surtseyan eruptions can be explained. The low-pressure expansion of superheated water in a coarsely mingled, saturated slurry can initiate Surtseyan cock's tail jets by imparting momentum to composite bombs at the jets' leading edges. Finer-scale mingling ensures that vapour formed within ballistic bombs discharges over timescales longer than their flight times, explaining fuzzy, steam-laden tephra jets. At the finest mingling scale, and for a narrow but plausible range of parameters, entrainment and vapourization of slurry can also drive fine phreatomagmatic fragmentation. The hypotheses presented here are consistent with classical qualitative models of Surtseyan jet dynamics, and work towards specifying how magmatic and external factors contribute individually and cooperatively to shallow subaqueous eruption dynamics.

Basaltic arc magmas may achieve calc-alkaline affinity through some combination of high magmatic H (sub 2) O, which delays the crystallization of silicates (most notably plagioclase), and high magmatic oxygen fugacity (fO (sub 2) ), which enhances the onset of magnetite crystallization. The relative importance of H (sub 2) O, fO (sub 2) , and magmatic bulk composition in generating calc-alkaline magma series, however, is not yet clearly resolved. Here, we present new measurements of the oxidation state of Fe (expressed as Fe (super 3+) /Sigma Fe ratio; a proxy for magmatic fO (sub 2) ), in combination with previously-published analyses, of mafic (Mg#> or =0.5) olivine-hosted melt inclusions from global arc volcanoes (Galunggung, Paricutin, Cerro Negro, and several volcanoes from the Mariana and Aleutian arcs), acquired using X-ray Absorption Near Edge Structure spectroscopy. We use the Tholeiitic Index (THI) of Zimmer et al., 2010 to quantify the calc-alkaline affinity of arc magma series (1 is more tholeiitic). These volcanoes span a range of calc-alkaline affinity, with THI ranging from 0.65 to 1.3. The Fe (super 3+) /Sigma Fe ratios of arc basalts, corrected for fractional crystallization to 6 wt.% MgO (i.e., Fe (super 3+) /Sigma Fe (sub 6.0) ) range globally from 0.15-0.31 and all but Galunggung are more oxidized than the more tholeiitic basaltic glasses from the Mariana trough back-arc basin (THI=1.4; Fe (super 3+) /Sigma Fe (sub 6.0) =0.185) or normal MORB (THI=1.6; Fe (super 3+) /Sigma Fe (sub 6.0) =0.167+ or -0.01). Our results show a strong correlation between THI and Fe (super 3+) /Sigma Fe (sub 6.0) ratios at these volcanoes, such that more calc-alkaline magmas contain a greater proportion of oxidized Fe. At the same time, the maximum dissolved H (sub 2) O contents of basaltic melt inclusions from these volcanoes also strongly correlate with THI, and with Fe (super 3+) /Sigma Fe (sub 6.0) ratios (although H (sub 2) O is not the direct cause of oxidation), which points to a slab-derived origin of both H (sub 2) O and oxidation and thus potentially links slab-derived fluids to the generation of calc-alkaline magma series. These correlations also illustrate the challenge of separating the effects of H (sub 2) O and fO (sub 2) on arc magmatic differentiation, as the two are difficult to isolate in nature. Yet, some volcanoes may shed light on this issue. Arc volcanoes with similar Fe (super 3+) /Sigma Fe (sub 6.0) or H (sub 2) O, but significantly different THI, may illustrate most clearly the isolated effects of the other variable.

Experiments are conducted within an air-filled tank 8.5 m long by 6.1 m wide by 2.6 m tall. Currents are generated by feeding heated powders down a chute into the tank at controlled rates to form dilute, particle-laden, turbulent gravity currents that are fed for 30 to 600 seconds. Powders include 5 mu m aluminum oxide, 25 mu m talc, 27 mu m walnut, 76 mu m glass beads and mixtures thereof. Experiments are scaled such that Froude, densimetric and thermal Richardson, particle Stokes and Settling numbers, and thermal to kinetic energy densities are all in agreement with dilute PDCs; experiments have lower Reynolds numbers that natural currents, but the experiments are fully turbulent, thus the large scale structures should be similar. The experiments are illuminated with 3 orthogonal laser sheets (650, 532, and 450 nm wavelengths) and recorded with an array of HD video cameras and a high speed camera (up to 3000 fps); this system provides synchronous observation of a vertical streamwise and cross-stream planes, and a horizontal plane. Ambient temperature currents tend to spread out radially from the source and have long run out distances, whereas warmer currents tend to focus along narrow sectors and have shorter run outs. In addition, when warm currents lift off to form buoyant plumes, lateral spreading ceases. The behavior of short duration currents are dominated by the current head; as eruption duration increases, current transport direction tends to oscillate back and forth (this is particularly true for ambient temperature currents). Turbulent structures in the horizontal plane show air entrainment and advection downstream. Eddies illuminated by the vertical cross-stream laser sheet often show vigorous mixing along the current margins, particularly after the current head has passed. In some currents, the head can persist as a large, vertically oriented vortex long after the bulk of the current has lifted off to form a coignimbrite plume. These unconfined experiments show that three-dimensional structures can affect PDC behavior and suggest that our typical cross-sectional or "cartoon" understanding of PDCs misses what may be very important parts of PDC dynamics.

Hence, there is need for common frameworks to aggregate available data, in order to characterize and quantify the phenomena at various spatial and temporal scales. Building on the Googas experience we are now extending its capability, particularly on the user side, by developing a new web environment for collecting and publishing data. We have started to create a new and detailed web database (MAGA: MApping GAs emissions) for the deep carbon degassing in the Mediterranean area. This project is part of the Deep Earth Carbon Degassing (DECADE) research initiative, lunched in 2012 by the Deep Carbon Observatory (DCO) to improve the global budget of endogenous carbon from volcanoes. MAGA database is planned to complement and integrate the work in progress within DECADE in developing CARD (Carbon Degassing) database. MAGA database will allow researchers to insert data interactively and dynamically into a spatially referred relational database management system, as well as to extract data. MAGA kicked-off with the database set up and a complete literature survey on publications on volcanic gas fluxes, by including data on active craters degassing, diffuse soil degassing and fumaroles both from dormant closed-conduit volcanoes (e.g., Vulcano, Phlegrean Fields, Santorini, Nysiros, Teide, etc.) and open-vent volcanoes (e.g., Etna, Stromboli, etc.) in the Mediterranean area and Azores. For each geo-located gas emission site, the database holds images and description of the site and of the emission type (e.g., diffuse emission, plume, fumarole, etc.), gas chemical-isotopic composition (when available), gas temperature and gases fluxes magnitude. Gas sampling, analysis and flux measurement methods are also reported together with references and contacts to researchers expert of the site. Data can be accessed on the network from a web interface or as a data-driven web service, where software clients can request data directly from the database. This way Geographical Information Systems (GIS) and Virtual Globes (e.g., Google Earth) can easily access the database, and data can be exchanged with other database. In details the database now includes: i) more than 1000 flux data about volcanic plume degassing from Etna (4 summit craters and bulk degassing) and Stromboli volcanoes, with time averaged CO2 fluxes of approximately 18000 and 766 t/d, respectively; ii) data from approximately 30 sites of diffuse soil degassing from Neapolitan volcanoes, Azores, Canary, Etna, Stromboli, and Vulcano Island, with a wide range of CO2 fluxes (from les than 1 to 1500 t/d) and iii) several data on fumarolic emissions ( approximately 7 sites) with CO2 fluxes up to 1340 t/day (i.e., Stromboli). When available, time series of compositional data have been archived in the database (e.g., for Campi Flegrei fumaroles). We believe MAGA data-base is an important starting point to develop a large scale, expandable data-base aimed to excite, inspire, and encourage participation among researchers. In addition, the possibility to archive location and qualitative information for gas emission/sites not yet investigated, could stimulate the scientific community for future researches and will provide an indication on the current uncertainty on deep carbon fluxes global estimates.

Studies of volcanic emissions are necessary for understanding volatile cycling from the mantle to the atmosphere. Gas compositions vary with volcanic activity, making it important to track their chemical variability over time. As studies become increasingly interdisciplinary, it is critical to have a mechanism to integrate decades of gas studies across disciplines. Despite the value of this research to a variety of fields, there is currently no integrated network to house all volcanic and hydrothermal gas data, making spatial, temporal, and interdisciplinary comparison studies time-consuming. To remedy this, we are working to establish a comprehensive database of volcanic gas emissions and compositions worldwide, as part of the Deep Carbon Observatory's DECADE (Deep Carbon Degassing) initiative. Volcanic gas data have been divided into two broad categories: 1) chemical analyses from samples collected directly at the volcanic source, and 2) measurements of gas concentrations and fluxes, such as remotely by mini-DOAS or satellite, or in-plume such as by multiGAS. The gas flux database effort is realized by the Global Volcanism Program of the Smithsonian Institution (abstract by Brendan McCormick, this meeting). The direct-sampling data is the subject of this presentation. Data from direct techniques include samples of gases collected at the volcanic source from fumaroles and springs, tephras analyzed for gas contents, filter pack samples of gases collected in a plume, and any other data types that involve collection of a sample. Data are incorporated into the existing framework of the Petrological Database, PetDB. Association with PetDB is advantageous as it will allow volcanic gas data to be linked to chemical data from lava or tephra samples, forming more complete ties between the eruptive products and the source magma. Eventually our goal is to have a seamless gas database that allows the user to easily access all gas data ever collected at volcanoes. This database will be useful in a variety of science applications: 1) correlating volcanic gas composition to volcanic activity; 2) establishing a characteristic gas composition or total volatile budget for a volcano or region in studies of global chemical cycles; 3) better quantifying the flux and source of volcanic carbon to the atmosphere. The World Organization of Volcano Observatories is populating a volcano monitoring database, WOVOdat, which centers on data collected during times of volcanic unrest for monitoring and hazard purposes. The focus of our database is to gain insight into volcanic degassing specifically, during both eruptive and quiescent times. Coordination of the new database with WOVOdat will allow comparison studies of gas compositions with seismic and other monitoring data during times of unrest, as well as promote comprehensive and cross-disciplinary questions about volcanic degassing.

Although CO (sub 2) contents of MORB glasses are strongly affected by degassing, rapid quenching and confining water pressure during submarine eruptions prevents H (sub 2) O, S, F and Cl from degassing, allowing us to study volatile-element systematics in relation to variations in the composition of the mantle source. Average compositions are 160+ or -150 ppm CO (sub 2) , 0.32+ or -0.36 wt% H (sub 2) O, 190+ or -190 ppm F, 1200+ or -450 ppm S and 140+ or -420 ppm Cl (2sigma standard variation). High Cl/Nb can be used as tracer of seawater alteration and/or assimilation of altered materials such as serpentinite. MORB samples that are depleted in Cl (and other incompatible elements) are the ones most affected by Cl addition. Filtering out all samples with Cl/Nb>20 results in lowering the average composition for Cl as well as the range in compositions for all volatiles (2sigma standard variation lowered by up to 50%). After filtering, the volatile content for unaltered MORB glasses is 180+ or -130 ppm CO (sub 2) , 0.33+ or -0.38 wt% H (sub 2) O, 200+ or -190 ppm F, 1150+ or -250 ppm S and 80+ or -230 ppm Cl. To account for variations in the degree of melting and/or crystallization, we normalize by a trace element with similar compatibility during mantle melting. Average ratios for unaltered MORB are 150+ or -70 for CO (sub 2) /Nb, 10+ or -8 for Cl/Nb, 2.4+ or -1.8 for F/Zr, 240+ or -100 for H (sub 2) O/Ce, and 240+ or -80 for S/Dy. For CO (sub 2) , the positive correlation with eruption depth at the global scale indicates that the CO (sub 2) content in MORB is mainly controlled by degassing, through a combination of equilibrium degassing (for samples with saturation pressure equals to equilibrium pressure, indicating equilibrium between the melt and the gas phase) and kinetic effects (for samples with saturation pressure greater than eruption pressure, indicating a delay in CO (sub 2) partitioning into the bubbles, thus an excess CO (sub 2) in the melt). We find that there is no correlation globally between H (sub 2) O/Ce or S/Dy ratios and proxies for mantle enrichment, such as La/Sm (sub N) ratio. In contrast, Cl/Nb and F/Zr ratios both tend to be elevated in enriched MORB (EMORB, with La/Sm (sub N) >1) relative to normal MORB (NMORB, with La/Sm (sub N) <1) at the global scale. The F/Zr ratio in particular shows promise as a proxy for variations in the mantle source, increasing along plume-affected segments. F/Zr ratio also correlates with radiogenic isotopes such as (super 206) Pb/ (super 204) Pb (both increase near the Sierra Leone hotspot for example) and can be tied to processes occurring at subduction zones where mantle heterogeneity is introduced. We will discuss global variations in MORB volatile concentrations in terms of location, nature and age of mantle components.

The natural sample is saturated in plagioclase + orthopyroxene + ilmenite + magnetite + apatite + zircon, despite low phenocryst abundances (<2.3%) and no microlite crystallization. Eruptive temperature and oxygen fugacity (+ or -1sigma ), on the basis of Fe-Ti oxide thermometry, are 852+ or - 12 degrees C and Delta NNO +0.3+ or -0.1. Plagioclase compositions range from 33-53 mol% An. Given the low crystallinity and absence of significant cooling, the progressive loss of dissolved melt H (sub 2) O during ascent best explains the broad range in phenocryst composition and the low crystallinity. Phase equilibrium experiments were conducted at temperatures and pressures ranging from 750-950 degrees C and 50-300 MPa, respectively. Experiments were conducted in a Ni-rich pressure vessel (Waspaloy) with Ni filler rod, which produces an intrinsic fO (sub 2) of Delta NNO +1+ or -0.5 (Geshwind & Rutherford, 1992) and pressurized with H (sub 2) O (where Ptotal=P (sub H2O) ). The results of the phase equilibrium experiments show that the most anorthitic plagioclase crystallized at approximately 3.95 wt% H (sub 2) O and the most albitic at approximately 3.49 wt% H (sub 2) O. Plagioclase crystallization in the natural sample ceased at relatively high melt H (sub 2) O content (3.49 wt%), which corresponds to a viscosity of 4.85 log (sub 10) Pa s (Hui & Zhang, 2007). To evaluate the effect of decompression rate on plagioclase crystallization, experiments were conducted on the rhyolite at two different continuous decompression rates, 3.0 MPa/hr and 0.8 MPa/hr. Two decompression experiments were conducted for each rate over two pressure integrals:150 to 89 MPa and from 150 to 58 MPa. The results from our study are combined with the results of single- and multi-step decompression experiments on rhyolites/rhyodacites from Geshwind & Rutherford (1995), Couch et al., (2003), and Martel & Schmidt (2003) with rates ranging from 0.12-27,000 MPa/hr. Comparison of the range of plagioclase compositions that grew in the decompression experiments with those predicted from phase equilibrium experiments, suggest that rapidly changing melt viscosity results in a kinetic barrier to plagioclase nucleation and crystallization in decompressing rhyolite/rhyodacite magmas. Initial results show that the viscosity at which plagioclase nucleation/growth ceases is dependent on the rate of change of viscosity of the liquid during decompression (R (super 2) =0.81). At slow decompression rates, plagioclase compositions track equilibrium compositions as a function of pressure, but as decompression rate increases (as rate of change of viscosity increases), plagioclase nucleation/growth ceases at increasingly higher pressures (i.e., higher melt H (sub 2) O contents and lower viscosities). We demonstrate that decompression rates of rhyolitic magmas can be obtained by using plagioclase compositions, plagioclase hygrometers, solubility and viscosity models, and decompression experiments from this study and the literature.

At the time of subduction initiation, melts may be produced by a combination of decompression and fluid-fluxed melting and the role of flux melting may increase as the subduction zone matures (Reagan et al., 2010, G3 11(3)). Immediately prior to subduction initiation, the mantle presumably has fO (sub 2) and fluid concentrations similar to mid-ocean ridge (MOR) source mantle (near the quartz-fayalite-magnetite buffer, QFM, and relatively dry). As subduction zones mature, slab fluids may become more dominant in melt generation as evidenced by increases in fluid-mobile trace element signatures, but the fO (sub 2) of slab fluids and temporal changes in the fO (sub 2) of erupted basalt remains undocumented. The Mariana forearc southwest of Guam records the initiation of Pacific plate subduction (Reagan et al., 2010). At the base, fore-arc basalts (FAB) erupted at the immediate onset of subduction (51-52 Ma) show minor traces of slab fluid influence and likely reflect decompression melting that occurred as mantle rose to accommodate the sinking Pacific plate. The FAB are overlain by 37-44 Ma "transitional" basalts whose fluid mobile trace element enrichments indicate that slab fluids have greater influence in their petrogenesis. These lavas provide the opportunity to directly constrain the timescales of mantle wedge oxidation during the initiation and maturation of an oceanic subduction zone. We present Fe (super 3+) /Sigma Fe ratios (mu -XANES) determined on FAB and transitional basalt glasses, paired with previously published major and trace element data. These glasses range in MgO from 2.75-7.56 wt% and have Fe (super 3+) /Sigma Fe ratios (0.171-0.208) that are slightly more oxidized than MORB (0.16), similar to Mariana trough lavas that reflect minor traces of slab fluid influence (Ba/La approximately 10). Melts last in equilibrium with the mantle (i.e. primary melts) are reconstructed from measured compositions with MgO>5.0 wt% by backtracking along empirical and modeled LLDs to yield primary Fe (super 3+) /Sigma Fe ratios. Pressures and temperatures of primary melt equilibration are calculated using Si-thermobarometry. FAB primary melts have fO (sub 2) and Ba/La ratios identical to modern Mariana trough magmas (QFM+0.4, Ba/La approximately 9). This suggests that the first melts formed during subduction initiation come from a mantle source that is already oxidized, perhaps because the volume of mantle that oxidized slab fluids interact with to produce melts is small. Primary transitional melts have fO (sub 2) approximately QFM+0.8 and Ba/La approximately 22, corresponding to an increase of 0.4 log units in 11 Ma. The modern mantle wedge fO (sub 2) is approximately QFM+1.4 and Ba/La can exceed 50 (e.g., at Guguan volcano). This increase in mantle wedge fO (sub 2) may be due to the increasing influence of slab fluids on melting processes in the mantle wedge through time, suggesting that oxidation occurs immediately and increases at a rate of 0.04 log units per Ma in the early stages of subduction magmatism.

Whilst degassing budgets have been determined for many species, these are inherently limited, being largely static and time-averaged, with coarse spatial resolution and inadequate (or lacking) error analyses. Herein we demonstrate the potential improvements in both regional and global budgets enabled by the use of a new relational volcanic emissions database that is being developed within the online database of Holocene volcanic activity maintained by the Global Volcanism Program (GVP), Volcanoes Of The World 4.0. Funded by the Deep Carbon Observatory's DECADE initiative and GVP, this new database will enable users to link volcanic degassing to coincident activity, which is central to our scientific objectives. This database will explicitly quantify data quality, which has largely been neglected in previous compilations and budget estimates. Observations reveal that volcanic emissions often vary by orders of magnitude, between peak syn-eruptive output and much lower persistent quiescent degassing. For example, timeseries analysis of SO2 emission data at Soufriere Hills points to strong periodicity in degassing, akin to that seen in other geophysical datasets (Nicholson et al., 2013, EPSL). By closely linking degassing and activity datasets, we show that for certain volcanoes a more representative characterization of long term volatile output can be achieved than by the use of a single mean value. We demonstrate that different activity/degassing states can be identified and assess the relative contribution of these states to a volcano's overall output. We also explore the potential for statistical models of degassing trends at well-studied volcanoes to be applied to more poorly-studied analogues, thus providing a means to estimate degassing behavior in these systems, where otherwise sparse, non-representative measurements must be relied upon. We also investigate means of extrapolating measurements of degassing at individual volcanoes to arc and ultimately global totals. Although a power law distribution of gas emissions may not be appropriate (Mori et al., 2013, JVGR), characterization of major degassing sources alone may closely approximate total arc and hence global emissions. We investigate this hypothesis, and consider whether a broad categorization of volcanoes based on their assumed degassing/activity characteristics can offer insight into how best to estimate emissions from those without direct measurements of degassing.

Explosive volcanic eruptions can also be lethal, cause widespread destruction, and generate considerable disturbances hundreds of kilometres away. An estimated 10% of the world's population lives within 100 km of a Holocene-active volcano, and so though infrequent on human timescales, volcanic activity poses a serious threat to societies around the world. While local and regional studies are key for understanding the behaviour of specific volcanoes, we gain valuable insights on the overall processes and mechanisms driving volcanism by investigating volcanism at a global level. Comprehensive and well-organized large database are the foundation for such endeavours; here we will showcase the utility of such a database for advancing our understanding of global volcanism. The Large Magnitude Explosive Volcanic Eruption (LaMEVE) database is a publicly available online compilation of all known large explosive Quaternary eruptions; here 'large' is defined as magnitude (M) 4 or great, corresponding to roughly 0.04 km (super 3) or more of magma erupted. The LaMEVE database contains information on over 1800 eruptions and its scope allows for a global assessment of rates of volcanism, eruption magnitude-frequency relationships and associated return periods, and quantification of the grave issue of under-reporting of volcanic eruptions. We will present results of our analysis in these three areas, and also discuss unexpected relations emerging from the database, which illustrates how the study of large datasets can generate new questions and lines of research. Finally, we will touch on how analysis of global volcanism can benefit research in other disciplines, such as climate studies, and also improve work at individual volcanoes.

Increasing active-layer depth and continued permafrost degradation will have far-reaching consequences for northern ecosystems with net feedbacks of unknown magnitude and direction to the climate system by altered regional hydrology and topography, vegetation composition and structure, land surface properties, and carbon dioxide (CO2) and methane (CH4) sink-source strengths. Several important questions are currently unanswered: 1) What is the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system? 2) How do these two different types of feedback differ between the sporadic, discontinuous and continuous permafrost zones? 3) Is the decrease (increase) in net CO2 (CH4) exchange measured over mostly tundra sites in the continuous permafrost zone generalizable to forested landscapes in the sporadic, discontinuous and continuous permafrost zones? To address these questions we initiated a meso-network of eddy covariance towers to quantify carbon (CO2, CH4), water and heat fluxes along a permafrost and climate gradient in the Taiga Plains, Northwest Territories, Canada including the following four sites from south to north (Fort Simpson-Norman Wells-Inuvik): Scotty Creek (boreal forest-peatland landscape with sporadic/discontinuous permafrost; fully operational since May 2013), Norman Wells (boreal forest with discontinuous/continuous permafrost; to be established in 2014), Havikpak Creek (boreal forest with continuous permafrost; partly operational since April 2013) and Trail Valley Creek (tundra with continuous permafrost; partly operational since April 2013). At all sites the eddy covariance measurements are or will be complemented by repeated surveys of surface and frost table topography and vegetation, by land cover-type specific fluxes of CO2 and CH4 measured with a static chamber technique, and by remote sensing-based footprint analysis. With this contribution, we report on the current status of meso-network development and present results from the first growing season of eddy covariance measurements at Scotty Creek, Trail Valley Creek and Havikpak Creek. Net CO2 uptake started earlier and was more pronounced at the forested Havikpak site compared to the tundra site (Trail Valley Creek), which experienced similar air temperatures but later snow melt than Havikpak. Overall, Scotty Creek experienced the strongest net CO2 uptake but also the highest nighttime respiration. At the same time, meteorological conditions at Scotty Creek are markedly different with higher air temperatures and earlier snowmelt than at the two northern sites.

Evidence is accumulating that long-distance migratory birds wintering in tropical climates have high overwinter survival probabilities and that winter food limitation mainly affects their fitness nonlethally by limiting energetic reserves necessary for successful reproduction. In contrast, the relative roles of direct mortality vs. indirect effects caused by food limitation have not been investigated thoroughly on short-distance migratory birds wintering in temperate zones, where they face thermal challenges. We performed the first test of the WFLH for a temperate migratory bird in the wild on the Swamp Sparrow (Melospiza georgiana), with a replicated plot-wide food supplementation experiment. In contrast to tropical, but consistent with other temperate-wintering migrants, Swamp Sparrows on unmanipulated plots showed relatively low apparent survival across the winter. Following food addition, birds (1) immigrated to experimental plots, which subsequently supported ~50% higher abundances, (2) experienced increases of within-season apparent survival of 8-10%, depending on age/sex class, and (3) had higher-scaled mass index values, all supporting winter food limitation. The last two findings are interrelated because birds with higher scaled mass had higher survival probabilities, further supporting direct effects of winter food limitation. Food limitation of fat reserves might also have indirect effects on reproductive success by limiting migration timing and survival during migration. Increases in scaled mass were higher in females, suggesting that they are disproportionately affected by food limitation, possibly through competition. Based on Robust Design Modeling, we found no support for emigration prior to food addition, indicating that our estimates of mortality are unbiased.

Unlike low petrologic type CR chondrites, alteration of metal appears to have played a central role in the formation of secondary minerals in GRA 06100. Differences in the mineralogy and chemical compositions of materials in GRA 06100 suggest that it experienced higher temperatures than other CR2 chondrites. Mineralogic features indicative of high temperature include: (1) exsolution of Ni-poor and Ni-rich metal from nebular kamacite; (2) formation of sulfides, oxides, and phosphates; (3) changes in the Co/Ni ratios; and (4) carbidization of Fe-Ni metal. The conspicuous absence of pentlandite may indicate that peak temperatures exceeded 600 degrees C. Opaques appear to have been affected by the action of aqueous fluids that resulted in the formation of abundant oxides, Fe-rich carbonates, including endmember ankerite, and the sulfide-silicate-phosphate scorzalite. We suggest that these materials formed via impact-driven metamorphism. Mineralogic features indicative of impact metamorphism include (1) the presence of sulfide-metal lodes; (2) the abundance of polymineralic opaque assemblages with mosaic-like textures; and (3) the presence of suessite. Initial shock metamorphism probably resulted in replacement of nebular Fe-Ni metal in chondrules and in matrix by Ni-rich, Co-rich Fe metal, Al-Ti-Cr-rich alloys, and Fe sulfides, while subsequent hydrothermal alteration produced accessory oxides, phosphates, and Fe carbonates. An extensive network of sulfide-metal veins permitted effective exchange of siderophile elements from pre-existing metal nodules with adjacent chondrules and matrix, resulting in unusually high Fe contents in these objects.

Reforestation to expand the langur's natural habitat became feasible when the present government mandated the use of native plants to increase the country's forest cover. For reforestation to benefit langur populations, however, the re-created habitat needs to be similar to the natural forest that provides food and space for their survival. This monkey's diet and the manner in which it uses its natural habitat are, therefore, being investigated as the first step. The diet and habitat use patterns of two groups, Tikira and Appu, were studied for 13 and 14 months respectively (n = 1695 hours). Scan sampling (with ten-minute sample periods) was used to record all activities observed in the groups and the trees on which these activities were performed. The plant parts eaten were also noted. Our results showed that Tikira used more species than Appu to perform all of its daily activities. Additionally, while the Tikira group used Dipterocarpus zeylanicus most frequently during most months, the Appu group had six species occupying the top rank during different months. Of the ten most frequently used species, only five were common to both groups, and the frequency of use of these plants was sometimes quite variable as well. With respect to diet, Appu used at least 27 species while Tikira fed on more than 41. The top-ranking food plants of the two groups were different, and among the top ten only four were the same. The top fifteen food plants of both groups constituted over 85% of their feeding records. Nineteen species eaten by Appu and 29 eaten by Tikira were exploited for less than two months, and the two groups ate no more than five species for more than seven months of the study. Although the two groups relied on different plants for much of their nutrition, nearly 86% and 74% of feeding observations of Appu (n = 422) and Tikira (n = 685), respectively, were of them feeding on leaves. Blossoms, fruits and petioles made up the remainder of the groups' diets. While these items contributed variable amounts to the monthly diet of both groups, none was exploited more frequently than leaves. The above results are compared to information from other non-human primates, and discussed with respect to reforestation. Two points are emphasized. One is that the langur living in its natural habitat is a typical folivore, unlike those living around home gardens. The other is that while field research is essential to reforest degraded habitats it must be conducted in conjunction with conservation education and other initiatives that are designed to dissuade people from destroying restored and intact natural habitats.

Radar reflections are hypothesized to originate from the same material interfaces that result in visible layering. As a first step towards verifying this assumption, this study uses signal analyses and geometric comparisons to quantitatively examine the relationship between reflectors and visible layers exposed in an NPLD outcrop. To understand subsurface structures and reflector geometry, reflector surfaces have been gridded in three dimensions, taking into account the influence of surface slopes to obtain accurate subsurface geometries. These geometries reveal reflector dips that are consistent with optical layer slopes. Distance-elevation profiling of subsurface reflectors and visible layer boundaries reveals that reflectors and layers demonstrate similar topography, verifying that reflectors represent paleosurfaces of the deposit. Statistical and frequency-domain analyses of the separation distances between successive layers and successive reflectors confirms the agreement of radar reflector spacing with characteristic spacing of certain visible layers. Direct elevation comparisons between individual reflectors and discrete optical layers, while necessary for a one-to-one correlation, are complicated by variations in subsurface structure that exist between the outcrop and the SHARAD observations, as inferred from subsurface mapping. Although these complications have prevented a unique correlation, a genetic link between radar reflectors and visible layers has been confirmed, validating the assumption that radar reflectors can be used as geometric proxies for visible stratigraphy. Furthermore, the techniques for conducting a stratigraphic integration have been generalized and improved so that the integration can be undertaken at additional locations.

Such data are hard to obtain, however, when difficult terrain, nocturnal habits, or lack of habituation make direct observation impractical. White-footed tamarins ( Saguinus leucopus ) are small primates endemic to Colombia that are in danger of extinction due to habitat loss, fragmentation, and the illegal pet trade. Here, we report the results of the first study to use radio-tracking to investigate white-footed tamarin ranging behavior. We recorded the movements of three neighboring tamarin groups simultaneously for 3 month using radio-telemetry. Home range sizes (estimated using both minimum convex polygon and fixed kernel contour methods) were substantially larger than reported in previous studies that did not use remote-tracking. Monte Carlo resampling procedures revealed that home range size differed significantly among the three groups but that the mean daily path length did not. As in other tamarin species, the degree of range overlap between neighboring social groups was high, ranging from 27 to 81%. Using a randomization test, we showed that the observed mean distance between groups was significantly lower than expected by chance for two of the three group dyads. This pattern of intergroup 'attraction,' in conjunction with substantial range overlap and high population density, implies that the Bellavista Forest, one of the few remaining habitats of Saguinus leucopus , may be saturated, and promoting habitat restoration should be a priority for the conservation of this species.

Nonetheless, considerable population structure might still occur in species with high dispersal ability due to current oceanographic and/or historical processes. Specifically, for the wider Caribbean and Gulf of Mexico, theoretical and empirical considerations suggest that populations inhabiting each of the following areas should be genetically distinct: Panama, Belize, Southwest Florida (Tampa), and Southeast Florida (Fort Pierce). This study tests the hypothesis of significant genetic differentiation in Palaemon floridanus populations across the wider Caribbean and Gulf of Mexico. Population level comparisons were conducted using sequences of the mtDNA COI. In agreement with predictions, AMOVA and pairwise FST values demonstrated population differentiation among most pairs of the studied populations. Only Panama and East Florida populations were genetically similar. An isolation-with-migration population divergence model (implemented in IMA2) indicated that population divergence with incomplete lineage sorting can be invoked as the single mechanism explaining genetic dissimilarity between populations from the east and west coast of Florida. Historical demographic analyses indicated demographic expansion of P. floridanus in some localities [recent in Panama and ancient in East Florida and the wider Caribbean (entire dataset)] but constant population in other localities (in Belize and West Florida). This study rejects the idea of panmixia in marine species with high long-distance dispersal ability. Contemporary and historical processes might interact in a complex manner to determine current phylogeographic patterns.

We studied social relationships and reproductive behavior of island foxes (Urocyon littoralis) on San Clemente Island (SCI) and San Miguel Island (SMI), off the coast of Southern California, using proximity logging collars. On both islands, pair members interacted more frequently and spent more time together than other types of dyads. On SCI, a high contact rate identified the same 10 mated pairs that were identified by a high degree of home-range overlap. A high contact rate also identified 3 mated pairs on SMI, 2 of which were associated with large pups 9-10 months old. On SMI, the number of contacts and amount of time that mates spent together per day varied across months and peaked in February, when most conceptions occur. Mates spent much less time together in April to June, the pup-rearing season. More unpaired male-female and male-male dyads interacted during January and February than in subsequent months. Paired males appeared to guard their mate during the period when she was receptive. The average duration of estrus was approximately 40 h. Paired females were in contact with other males in addition to their mate near the time they were presumably in estrus, and paired males were in contact with other females in addition to their mate. The relatively short duration of estrus, combined with asynchrony of estrus among females, enabled paired males to leave their mate and seek extrapair copulations without risk of cuckoldry. Proximity logging collars provide a new opportunity to learn about these temporal aspects of social and reproductive behavior in canids.

However, experimental data to establish clear cause-and-effect relationships in naturally complex field conditions are scarce in aquatic environments. Here, we describe the design and performance of a unique outdoor enclosure facility used to simulate warming, increased nitrogen supply, and both factors combined in a littoral freshwater wetland dominated by common reed, Phragmites australis. The experimental system effectively simulated a 2.8 degree C climate warming scenario over an extended period, capturing the natural temperature variations in the wetland at diel and seasonal scales with only small deviations. Excess nitrogen supply enhanced nitrate concentrations especially in winter when it was associated with increased concentration of ammonium and dissolved organic carbon. Nitrogen also reduced dissolved oxygen concentrations, particularly in the summer. Importantly, by stimulating biological activity, warming enhanced the nitrogen uptake capacity of the wetland during the winter, emphasizing the need for multifactorial global change experiments that examine both warming and nitrogen loading in concert. Establishing similar experiments across broad environmental gradients holds great potential to provide robust assessments of the impacts of climate change on shallow aquatic ecosystems.

Characteristic of this genus is a long larval and pelagic juvenile phase, which could potentially confer large dispersal capacity. We sampled its mitochondrial DNA to answer the following questions: What speciation events have led to the formation of the extant species? How do they correlate with geological and oceanographic events? Are M. dentatus and M. martinicus geminate species formed by the rise of the Isthmus of Panama? Is there genetic structure between conspecific populations? We constructed a phylogeny of Mulloidichthys, based on the ATPase-8 and ATPase-6 genes and the control region. We estimated degree of genetic structuring in four species. The phylogeny revealed that the Indo-Pacific M. pflugeri diverged first, followed by M. flavolineatus, also from the Indo-Pacific, followed by the central Pacific M. mimicus. The most recent splitting event resulted in a tritomy composed of the Atlantic M. martinicus, the eastern Pacific M. dentatus and the Indo-Pacific M. vanicolensis. The differentiation between M. martinicus and M. dentatus was substantially smaller than divergence in the same DNA fragments in eight other fish genera likely to have been split by the rise of the Isthmus of Panama. Low genetic structuring was found between conspecific populations of Mulloidichthys, even across the entire Indo-Pacific. Only populations at Clipperton Atoll and at Ascension Island in the Atlantic were genetically isolated from other conspecific populations. The oldest extant species of Mulloidichthys are found in the Indo-Pacific. Younger species probably maintained genetic contact between the Atlantic and the Indo-Pacific until the late Pleistocene. The low degree of genetic structuring and the unusual recent connections around the globe are likely to be the result of the large, highly mobile, and long-lived juvenile phase in this genus.Original Abstract: All tropical oceans.

In this study, we examine a particularly rich assemblage of morphologically basal moths that contribute significantly toward the understanding of early lepidopteran biodiversity. Our documentation of early fossil moths involved light- and scanning electron microscopic examination of specimens, supported by various illumination and specimen contrast techniques. A total of 20 moths were collected from the late Middle Jurassic Jiulongshan Formation in Northeastern China. Our principal results were the recognition and description of seven new genera and seven new species assigned to the Eolepidopterigidae; one new genus with four new species assigned to the Mesokristenseniidae; three new genera with three new species assigned to the Ascololepidopterigidae fam. nov.; and one specimen unassigned to family. Lepidopteran assignment of these taxa is supported by apomorphies of extant lineages, including the M1 vein, after separation from the M2 vein, subtending an angle greater than 60 degrees that is sharply angulate at the junction with the r-m crossvein (variable in Trichoptera); presence of a foretibial epiphysis; the forewing M vein often bearing three branches; and the presence of piliform scales along wing veins. The diversity of these late Middle Jurassic lepidopterans supports a conclusion that the Lepidoptera-Trichoptera divergence occurred by the Early Jurassic.

AN - 1459976960; 24156748 AB - There are few available in situ remediation options for Hg contaminated sediments, short of capping. Here we present the first tests of activated carbon and other sorbents as potential in situ amendments for remediation of mercury and methylmercury (MeHg), using a study design that combined 2 L sediment/water microcosms with 14 day bioaccumulation assays. Our key end points were pore water concentrations, and bioaccumulation of total Hg and MeHg by a deposit-feeding oligochaete Lumbriculus variegatus. Four amendments were tested: an activated carbon (AC); CETCO Organoclay MRM (MRM); Thiol-SAMMS (TS), a thiol-functionalized mesoporous silica; and AMBERSEP GT74, an ion-exchange resin. Amendments were tested in four separate microcosm assays using Hg-contaminated sediments from two freshwater and two estuarine sites. AC and TS amendments, added at 2-7% of the dry weight of sediments significantly reduced both MeHg concentrations in pore waters, relative to unamended controls (by 45-95%) and bioaccumulation of MeHg by Lumbriculus (by between 30 and 90%). Both amendments had only small impacts on microcosm surface water, sediment and pore water chemistry, with the exception of significant reductions in pore water dissolved organic matter. The effectiveness of amendments in reducing bioaccumulation was well-correlated with their effectiveness in increasing sediment:water partitioning, especially of MeHg. Sediments with low native sediment:water MeHg partition coefficients were most effectively treated. Thus, in situ sediment sorbent amendments may be able to reduce the risk of biotic Hg and MeHg uptake in contaminated sediments, and subsequent contamination of food webs.

Yet, among amphibians, the physiological impacts of short-term temperature variation are largely unknown. Using an ex situ population of Cryptobranchus alleganiensis, an aquatic North American salamander, we tested the hypothesis that naturally occurring periods of temperature variation negatively impact amphibian health, either through direct effects on immune function or by increasing physiological stress. We exposed captive salamanders to repeated cycles of temperature fluctuations recorded in the population's natal stream and evaluated behavioral and physiological responses, including plasma complement activity (i.e. bacteria killing) against Pseudomonas aeruginosa, Escherichia coli and Aeromonas hydrophila. The best-fit model ( Delta AICc=0, wi=0.9992) revealed 70% greater P. aeruginosa killing after exposure to variable temperatures and no evidence of thermal acclimation. The same model predicted 50% increased E. coli killing, but had weaker support ( Delta AICc=1.8, wi=0.2882). In contrast, plasma defenses were ineffective against A. hydrophila, and other health indicators (leukocyte ratios, growth rates and behavioral patterns) were maintained at baseline values. Our data suggest that amphibians can tolerate, and even benefit from, natural patterns of rapid warming/cooling. Specifically, temperature variation can elicit increased activity of the innate immune system. This immune response may be adaptive in an unpredictable environment, and is undetectable by conventional health indicators (and hence considered cryptic). Our findings highlight the need to consider naturalistic patterns of temperature variation when predicting species' susceptibility to climate change.

Among the first pottery analyzed was that from two Guatemalan sites occupied by the ancient Maya during 600-900 A.D. From a humble beginning of nine samples, the database of Maya ceramics now exceeds 40,000 analyses with geographical coverage of more than 450 archaeological sites located throughout southern Mexico, Guatemala, Belize and western Honduras. The geo-located sources of Maya ceramic data have been supplemented by the analyses of approximately 1,800 whole ceramic vessels held in national and international collections. This database is the product of three different nuclear laboratories, each using different analytical standards. Over time archaeological research emphasis has moved beyond merely attempting to document the long-distance movement of pottery to a context that is far more site-specific and socially embedded. Along the way, much has been learned about the chemical nature of the ceramic compositional system, the need for reasoned selection of element concentrations used to model that system, and the appropriate use of numerical procedures to coax out patterns of archaeological useful information. These considerations played a significant role the following brief example using INAA to assist in the recovery of ancient Maya political ritual and history.

Here, we present newly recognized oral region homologies, based on the Universal Elemental Homology model for skeletal plates, in a wide range of fossil taxa. The oral region of echinoderms is mainly composed of the axial, or ambulacral, skeleton, which apparently evolved more slowly than the extraxial skeleton that forms the majority of the body. Recent phylogenetic hypotheses have focused on characters of the extraxial skeleton, which may have evolved too rapidly to preserve obvious homologies across all these groups. The axial skeleton conserved homologous suites of characters shared between various edrioasteroids and specific blastozoans, and between other blastozoans and crinoids. Although individual plates can be inferred as homologous, no directly overlapping suites of characters are shared between edrioasteroids and crinoids. Six different systems of mouth (peristome) plate organization (Peristomial Border Systems) are defined. These include four different systems based on the arrangement of the interradially-positioned oral plates and their peristomial cover plates, where PBS A1 occurs only in plesiomorphic edrioasteroids, PBS A2 occurs in plesiomorphic edrioasteroids and blastozoans, and PBS A3 and PBS A4 occur in blastozoans and crinoids. The other two systems have radially-positioned uniserial oral frame plates in construction of the mouth frame. PBS B1 has both orals and uniserial oral frame plates and occurs in edrioasterid and possibly edrioblastoid edrioasteroids, whereas PBS B2 has exclusively uniserial oral frame plates and is found in isorophid edrioasteroids and imbricate and gogiid blastozoans. These different types of mouth frame construction offer potential synapomorphies to aid in parsimony-based phylogenetics for exploring branching order among stem groups on the echinoderm tree of life.

III. THE FIRST SEARCH FOR AN EXOMOON AROUND A HABITABLE-ZONE PLANET AN - 1705081019; PQ0001811855 AB - Kepler-22b is the first transiting planet to have been detected in the habitable zone of its host star. At 2.4 R sub([+ in cicle]), Kepler-22b is too large to be considered an Earth analog, but should the planet host a moon large enough to maintain an atmosphere, then the Kepler-22 system may yet possess a telluric world. Aside from being within the habitable zone, the target is attractive due to the availability of previously measured precise radial velocities and low intrinsic photometric noise, which has also enabled asteroseismology studies of the star. For these reasons, Kepler-22b was selected as a target-of-opportunity by the "Hunt for Exomoons with Kepler" (HEK) project. In this work, we conduct a photodynamical search for an exomoon around Kepler-22b leveraging the transits, radial velocities, and asteroseismology plus several new tools developed by the HEK project to improve exomoon searches. We find no evidence for an exomoon around the planet and exclude moons of mass M sub(S) > 0.5 M sub([+ in cicle]) to 95% confidence. By signal injection and blind retrieval, we demonstrate that an Earth-like moon is easily detected for this planet even when the time-correlated noise of the data set is taken into account.

201516700 AB - Charles Halfmoon was a neglected First Nations writer of the mid-nineteenth century. He was a speaker of Munsee from Munceytown, Ontario, who worked as an assistant to the local Methodist mission, being referred to as 'Local Preacher' (Halfmoon 1842) and as 'Assistant Missionary.' (Halfmoon 1874). Presumably he served as the interpreter for the Munsee-speaking congregation. If the age of 45 given for him in the 1861 census is precise, he was born in 1815 or 1816. He married Elizabeth Dodson, also of Munceytown, on November 5, 1837 in the Wesleyan Methodist Church. He is referred to as deceased in 1886 (Wampum and Hogg 1886:iv). His Indian name, which may be phonemicized as /ke-sohwi-s/ (in the modern practical orthography Keeshohwiish) has no obvious interpretation.

Productivity in the Choptank is predominantly nitrogen-limited, and most nitrogen inputs occur via discharge of high-nitrate groundwater into the river system's surface waters. However, spatial patterns in the magnitude and quality of groundwater discharge are not well understood. In this study, we surveyed the activity of (super 222) Rn, a natural groundwater tracer, in the Choptank's main tidal channel, the large tidal tributary Tuckahoe Creek, smaller tidal and non-tidal tributaries around the basin, and groundwater discharging into those tributaries, measuring nitrate and salinity concurrently. (super 222) Rn activities were <100 Bq m (super -3) in the main tidal channel and 100-700 Bq m (super -3) in the upper Choptank River and Tuckahoe Creek, while the median Rn activities of fresh tributaries and discharging groundwater were 1,000 and 7,000 Bq m (super -3) , respectively. Nitrate-N concentrations were <0.01 mg L (super -1) throughout most of the tidal channel, 1.5-3 mg L (super -1) in the upper reaches, up to 13 mg L (super -1) in tributary samples, and up to 19.6 mg L (super -1) in groundwater. Nitrate concentrations in tributary surface water were correlated with Rn activity in three of five sub-watersheds, indicating a groundwater nitrate source. (super 222) Rn and salinity mass balances indicated that Rn-enriched groundwater discharges directly into the Choptank's tidal waters and suggested that it consists of a mixture of fresh groundwater and brackish re-circulated estuarine water. Further sampling is necessary to constrain the Rn activity and nitrate concentration of discharging groundwater and quantify direct discharge and associated nitrogen inputs.

Stresses induced by this lithospheric flexure can have a strong influence on magma ascent pathways from the mantle source region to the surface. Here we propose that flexural stresses exert control over the shapes of volcanic edifices on Venus, applying criteria for magma ascent expressed in terms of stress orientations (can vertical dikes form?) and gradients (is magma squeezed upward or downward in a vertical dike?) to determine favored magma ascent paths and locations. For conical edifices emplaced on lithosphere with high elastic thickness T (sub e) , (e.g., > 40 km) both sets of magma ascent criteria are satisfied over the entire lithosphere, allowing essentially unimpeded ascent of magma to the surface and the formation of relatively steep edifices. However, for lower values of T (sub e) , high adverse stress gradients tend to cut off magma ascent beneath the summit, instead favoring lateral transport of magma at depth to distal regions with gentler stress gradients, resulting in domical edifice shapes. At the lowest values of T (sub e) (< 10 km), large short-wavelength deflections of the lithosphere tend to produce narrow and widely spaced zones of magma ascent: Such zones may produce annular ridges of volcanic material, thereby generating forms characteristic of a subset of features known as "coronae" on Venus. Another subset of coronae may form by intrusive-based generation of annular fractures at the edge of the summit region of domical edifices, as proposed for Alba Mons on Mars.

The procedures used to determine Fe counting rates are presented, along with a global map, constituting the necessary initial step to quantify Fe abundances. While the final calibration of orbital data to absolute concentrations has not been determined, the range of fully corrected Fe counting rates is compared with that of Fe in howardites. We find that the global distribution of corrected Fe counting rates is generally consistent with mineralogy and composition determined independently by other instruments on the Dawn spacecraft, including measurements of pyroxene absorption bands by the Visible and Infrared Spectrometer and Framing Camera, and an index of diogenitic materials provided by neutron absorption measurements by GRaND. In addition, there is a distinctive low Fe region in the western hemisphere that was not reported by reflectance or optical observations, possibly indicating the presence of a cumulate eucrite component in Vesta's regolith.

The specimen, an Edmontosaurus annectens is remarkable in having exceptional three-dimensional preservation of soft tissue around the skeleton, indicating rapid burial. A well-preserved palynological assemblage dominated by fern and bryophyte spores, with lesser gymnosperm and angiosperm pollen was recovered. Sparse fresh-water algae and marine dinoflagellate cysts were also recorded. The palynofacies is dominated by wood fragments, including charcoal, with little amorphous organic matter. The presence of some typical pollen taxa of the Wodehouseia spinata Assemblage Zone including Striatellipollis striatellus, Tricolpites microreticulatus, Leptopecopites pocockii as well as a diverse suite of Aquilapollenites, is fully consistent with a Late Cretaceous (late Maastrichtian) age. The palynoflora indicates a local vegetation composed of a canopy of conifers dominated by Pinaceae and a minor sub-canopy of Taxodium and cycads, as well as an understory of hydrophilous ferns, mosses and herbaceous angiosperms, indicative of a warm and humid climate - an environment where this specific hadrosaur roamed over 66 million years ago.

Harzburgitic diogenites are the main olivine-bearing lithology in the howardite-eucrite-diogenite (HED) meteorites, a group of samples thought to originate from Vesta. Here, we examine all the Antarctic harzburgites and estimate that, on scales resolvable by Dawn, olivine abundances in putative harzburgite exposures on the surface of Vesta are likely at best in the 10-30% range, but probably lower due to impact mixing. We examine the visible/near-infrared spectra of two harzburgitic diogenites representative of the 10-30% olivine range and demonstrate that they are spectrally indistinguishable from orthopyroxenitic diogenites, the dominant diogenitic lithology in the HED group. This suggests that the visible/near-infrared spectrometer onboard Dawn (VIR) will be unable to resolve harzburgites from orthopyroxenites on the surface of Vesta, which may explain the current lack of identification of harzburgitic diogenite on Vesta.

From a circular, polar low-altitude mapping orbit, GRaND sampled the regolith to decimeter depths with a spatial resolution of about 300 km. At this spatial scale, the variation in neutron absorption is about seven times lower than that of the Moon. The observed variation is consistent with the range of absorption for howardite whole-rock compositions, which further supports the connection between Vesta and the howardite, eucrite, and diogenite meteorites. We find a strong correlation between neutron absorption and the percentage of eucritic materials in howardites and polymict breccias, which enables petrologic mapping of Vesta's surface. The distribution of basaltic eucrite and diogenite determined from neutron absorption measurements is qualitatively similar to that indicated by visible and near infrared spectroscopy. The Rheasilvia basin and ejecta blanket has relatively low absorption, consistent with Mg-rich orthopyroxene. Based on a combination of Fe and neutron absorption measurements, olivine-rich lithologies are not detected on the spatial scales sampled by GRaND. The sensitivity of GRaND to the presence of mantle material is described and implications for the absence of an olivine signature are discussed. High absorption values found in Vesta's "dark" hemisphere, where exogenic hydrogen has accumulated, indicate that this region is richer in basaltic eucrite, representative of Vesta's ancient upper crust.

These observations are consistent with the presence of large (> or =8 X 10 (super 4) km (super 2) ) regions with distinct, HED-like elemental compositions. The results agree broadly with other global measurements, such as the macroscopic neutron absorption cross section and spectral reflectance-derived mineralogic maps. Two distinct regions with eucrite-like elemental compositions have been identified, the first located primarily within the Lucaria and Marcia quadrangles and the second within Oppia quadrangle. The former region is collocated with some of the oldest, most heavily cratered terrain on Vesta. The interior of the 500 km diameter Rheasilvia impact basin is found to have a composition that is consistent with diogenite-like material. Taken together, these observations support the hypothesis that Vesta's original crust was composed of basaltic outflows in the form of eucritic-like material and that the Rheasilvia-basin-forming impact exposed lower-crustal, diogenite-like material. These measurements also constrain the maximum amount of mesosiderite-like material to <10% for each 15 X 15 degrees surface element. Abstract Copyright The Meteoritical Society, 2013.

The evidence includes Vesta's petrologic complexity, detailed spectroscopic characteristics, unique space weathering, diagnostic geochemical abundances and neutron absorption characteristics, chronology of surface units and impact history, occurrence of exogenous carbonaceous chondritic materials in the regolith, and dimensions of the core, all of which are consistent with HED observations and constraints. Global mapping of the distributions of HED lithologies by Dawn cameras and spectrometers provides the missing geologic context for these meteorites, thereby allowing tests of petrogenetic models and increasing their scientific value.

The results of this analysis are then combined with data from the howardite-eucrite-diogenite (HED) meteorites and the Dawn mission to constrain Vesta's bulk composition. Twelve chondritic compositions are considered, comprising seven carbonaceous, three ordinary, and two enstatite chondrite groups. Our analysis excludes CI and LL compositions as plausible Vesta analogs, as these are predicted to have a negative metal fraction. Second, the MELTS thermodynamic calculator is used to show that the enstatite chondrites, the CV, CK and L-groups cannot produce Juvinas-like liquids, and that even for the other groups, depletion in sodium is necessary to produce liquids of appropriate silica content. This conclusion is consistent with the documented volatile-poor nature of eucrites. Furthermore, carbonaceous chondrites are predicted to have a mantle too rich in olivine to produce typical howardites and to have Fe/Mn ratios generally well in excess of those of the HEDs. On the other hand, an Na-depleted H-chondrite bulk composition is capable of producing Juvinas-like liquids, has a mantle rich enough in pyroxene to produce abundant howardite/diogenite, and has a Fe/Mn ratio compatible with eucrites. In addition, its predicted bulk-silicate density is within 100 kg m (super -3) of solutions constrained by data of the Dawn mission. However, oxidation state and oxygen isotopes are not perfectly reproduced and it is deduced that bulk Vesta may contain approximately 25% of a CM-like component. Values for the bulk-silicate composition of Vesta and a preliminary phase diagram are proposed. Abstract Copyright The Meteoritical Society, 2013.

Its age, however, remains controversial. In its southern and western two-thirds the Dunkard is comprised largely of red beds, sandstone and siltstone channel deposits and paleosols. In its thickest, most northerly exposures, in southwestern Pennsylvania, northern West Virginia, and east-central Ohio, much of the lower part of the unit is composed of coals, non-marine limestones and gray, often calcareous, paleosols. Age dating is confounded by the non-marine nature of the deposit and by the lack of dateable volcanic ash beds. Dunkard fossils include plants, vertebrates, and both aquatic and terrestrial invertebrates. Most of the fossil groups point to an age very close to, if not including, the Pennsylvanian-Permian boundary, though the exact position of that boundary is uncertain. Callipterids make their first appearance in the Dunkard flora in the middle of the Washington Formation and continue into the Greene Formation, but in different beds from those containing wetland floral elements. Publication of these plants in the "Permian Flora" of Fontaine and White (1880) created an immediate controversy about the age of the unit because Callipteris conferta (now Autunia conferta) was, at the time, considered to be an index fossil for the base of the Permian. Subsequent collecting has revealed these callipterds to comprise four species: A. conferta, Autunia naumannii, Lodevia oxydata and Rhachiphyllum schenkii. Callipterids--and the conifers with which they are sometimes associated--are typically found in seasonally dry equatorial environments and most likely constitute an environmentally controlled biofacies. This biofacies is not well known, resulting in limited biostratigraphic utility. Abstract Copyright (2013) Elsevier, B.V.

Late Pennsylvanian and Early Permian soil-mineral crystallization temperatures are estimated through the study interval with oxygen and hydrogen isotope compositions of paleopedogenic phyllosilicates and hematites taken from paleosol profiles. Considering monthly soil- and air-temperature measurements from modern equatorial Africa, phyllosilicate crystallization temperatures likely exceed surface air temperatures by approximately 2+ or -2 degrees C. Furthermore, the warming trend emerges from Pennsylvanian-age soil mineral crystallization temperatures, which are substantially cooler than soil temperatures observed in the modern lowland tropics, to Permian-age soil mineral crystallization temperatures, which are equivalent to, or slightly exceed, soil temperatures observed in modern lowland tropics. This record of mineral crystallization temperatures occurs at a time when some sources indicate the onset of the largest single glaciation of the Late Paleozoic Ice Age. The temperature change indicated by these paleosol minerals is accompanied by a unidirectional, irreversible change in the composition of tropical lowland vegetation. This transition delineates the magnitude and characteristics of vegetational changes in the modern tropics that might accompany continued atmospheric warming. Times of low surface temperatures coincide with a typical Late Pennsylvanian, tropical Pangean, "wet" biome dominated by Sigillaria, Macroneuropteris, other pteridosperms and marattialean ferns. This plant assemblage is replaced spatially by a xeromorphic biome dominated by conifers, callipterids, and other seed plants, characteristic of the tropical Permian across western and central Pangea. The fully xeromorphic flora appears initially in sub-meter-scale beds within outcrops otherwise characterized by wet flora, and becomes predominant once peak surface temperatures were reached in the earliest Permian. A narrow stratigraphic interval (20m) separates these two biomes in the region, marking what was to be a permanent floristic change in western Pangea. The lower diversity floras of seasonally dry habitats apparently migrated from drier extrabasinal areas into increasingly dry landscapes formerly dominated by the wet biome. This study documents the regional disappearance of an entire tropical biome with a net reduction of biodiversity accompanying rapid environmental warming. Abstract Copyright (2013) Elsevier, B.V.

The transition strata, from bottom to top, include the Late Pennsylvanian Pittsburgh and Uniontown formations of the Monongahela Group, the Waynesburg and Washington formations of the Dunkard Group and the Permian Greene Formation of the Dunkard. Variations in the amount of precipitation were the predominant allocyclic control on stratigraphic variations in terrestrial organic productivity, lacustrine base levels, basin-scale weathering, water table and pedogenesis, sediment supply, and sedimentary geochemistry. Tectonic subsidence controlled accommodation space and basin configuration. Eustasy had little or no effect on the stratigraphy of strata deposited in this continental basin during the Pennsylvanian-Permian transition. Autocyclic processes were the predominant spatial control on architecture of alluvial plain aggradation. Paleosols, delineating regional unconformities, show a gradual upward transition from kaolinitic underclay paleosols indicative of a humid climate in the Late Pennsylvanian Monongahela Group to petrocalcic paleosols indicative of a dry subhumid to semiarid climate during deposition of Dunkard strata. As in the Monongahela Group, the Dunkard Group Waynesburg and Washington Formations contain multi-bedded nonmarine lacustrine limestones with subareal exposure features. These limestones grade laterally into petrocalcic paleo-Vertisols in the up-dip alluvial plain. Subareal exposure features are uncommon in centimeter-scale micritic limestones in the Permian Greene Formation; equivalent up-dip paleosols have been lost to erosion. Coal bed continuity, thickness, and quality, also decrease up-section from the very thick (>m) and laterally continuous Pittsburgh Coal at the base of the Monongahela Group to thin (cm scale) and laterally discontinuous coal beds that unconformably overlie the paleosol/underclay/limestone complexes in the Greene Formation. Lacustrine shales and impure (wacke) fluvio-lacustrine sandstones, commonly with a weak pedogenic overprint, generally overlie coal beds. During accumulation of Monongahela and Dunkard (MDG) strata within the basin center, unconformities at the tops of regional paleosols, overlain by lacustrine strata, suggest allocyclic-induced repeated rise and fall of lacustrine conditions in a lacustrine-fan-delta complex analogous to the Okavango Basin and fan in Namibia, Southern Africa, and/or the Pantanal in southern Brazil. During maximum lake levels, progradation of fluvio-deltaic systems resulted in laminated shale conformably overlain by dark shale and flat-bottomed distributary mouth bar siltstones and sandstones. Prograding distributaries and/or fluvial channels subsequently incised the flat-bottom mouth bar sands. Where basin margin strata are preserved, south of the basin center, depositional environments consist of aggrading alluvial plain sequences with paleosols, fluvial channel sands, and flood plain deposits. Anastomosing fluvial systems prograded across a low gradient ( approximately 1ft/mile; approximately 20cm/km) alluvial plain into the basin center. A weak pedogenic overprint, marked by ubiquitous root penetrations, occurs throughout most basin-centered fluvial deposits. The subtle but continuous decline in the repetition of cyclic lithostratigraphy up-section in the MDG, particularly in the Greene Formation, appears to be the result of a 10-myr-climate transition from the humid to dry subhumid climate cycles of the Late Pennsylvanian to the equable semiarid to arid climate of the Middle Permian in North America. Cyclothems, common in Pennsylvanian strata, become less distinct up-section in the Dunkard because of decreasing development of underclays, coal, and limestone. This 30-myr period of transition from the humid Pennsylvanian to the arid Permian has been referred to as the Dyassic Period. Abstract Copyright (2013) Elsevier, B.V.

Previous interpretations of their environments of deposition range from brackish coastal mudflats to hydrologically open freshwater lake complexes with peat-forming vegetated marshes to semi-closed or closed, possibly saline, shallow lakes developed on a distal alluvial plain. Ostracode wackestones/packstones, some exhibiting laminations, and with fish debris, articulated ostracode shells and phosphatic clasts define the lower portions of limestone beds or benches, passing upward into ostracode-peloidal wackestones/packstones and intraclastic-skeletal-peloidal packstones/grainstones. Desiccation features and rooting structures, which are developed in the upper portions of the limestones, record subaerial exposure, pedogenic alteration and desiccation. Pseudomicrokarst and caliche-like vadose and early diagenetic phreatic cements suggest a seasonally dry subhumid to semi-arid regional climate. Many of the sedimentologic and diagenetic features of the limestones are characteristic of palustrine carbonates, which coupled with their stratigraphic relation to paleo-Vertisols, siliciclastics, and coals, indicate that they formed in broad seasonal wetland-pond complexes that developed on distal regions of a low-gradient, distal alluvial plain under seasonally dry subhumid to semi-arid climates. Integration of Sr isotopic compositions of shark teeth with previously published stable isotope compositions of the limestones suggests that these purely continental environments were hydrologically semi-closed to closed systems.

The ostracode associations include: (1) a Pennsylvanian (Virgilian; Gzhelian) marine association dominated Hollinella cushmani with abundant brachiopods and foraminifera exclusive to the GIL 30 Core in Kentucky (Illinois Basin); (2) a latest Pennsylvanian (Virgilian; Gzhelian) brackish association dominated by Geisina upsoni (Kellet), Cavellina nebrascensis (Geintz), and Velatomorpha fittsi (Kellet) exclusive to the GIL 30 Core in Kentucky (Illinois Basin); and (3) an uppermost Permian (Asselian/Sakmarian) association of nonmarine taxa dominated by Whipplella cuneiformis (Holland), Whipplella parvula (Holland), Paleodarwinula hollandi (Scott), and Haworthina bulleta (Harris and Lalicker) that occurs in the uppermost continental facies of both the Illinois and Dunkard Basins. A comparable nonmarine association of Paleodarwinula hollandi and Whipplella bretonensis (Copeland) occurs in the Bolsovian to Cantabrian (Moscovian to Kasimovian) coal measures of the Maritimes Basin of Atlantic Canada. The data presented herein provides new information about the withdrawal of marine waters from several major late Paleozoic basins in eastern North America. Mid-continental marine influence persisted into the latest Pennsylvanian to earliest Permian during deposition in the eastern Illinois Basin on the western Appalachian coastal plain. The uppermost nonmarine association of nonmarine Ostracoda in both the Illinois Basin and Dunkard Basin indicates a synchronous development of aquatic freshwater faunas during Lower Permian times. With increasing geographic isolation of the eastern North American basins, the dispersal and radiation of Ostracoda in these basins was apparently facilitated by brood rearing as demonstrated by the dominance of the Platycopina and Darwinulocopina.

Correlation of the Dunkard Group to the Pennsylvanian-Permian boundary has long been debated. Fossil vertebrates from the Dunkard Group include paleoniscoids, dipnoans, a rhipidistian crossopterygian, selachians, lepospondyl and temnospondyl amphibians, diadectomorphs, primitive amniotes, eureptiles and eupelycosaurs. These vertebrates represent two biostratigraphically distinct assemblages, one from the Waynesburg and Washington Formations and the other from the overlying Greene Formation. Comparison of the Dunkard vertebrate biostratigraphy to a vertebrate biostratigraphy and biochronology developed in New Mexico-Texas allows correlation to the Coyotean (= latest Virgilian-middle Wolfcampian) and Seymouran (late Wolfcampian-early Leonardian) land-vertebrate faunachrons. Tetrapod taxa from the Waynesburg and Washington Formations include Edops and Protorothyris, Coyotean index taxa, as well as the characteristic Coyotean taxa Trimerorhachis, Diadectes, Edaphosaurus and Dimetrodon. Significantly, these Dunkard taxa are best known from the Archer City Formation in Texas, which is late Coyotean (=middle Wolfcampian). The Greene Formation contains the eupelycosaur Ctenospondylus, an index taxon of the Seymouran land-vertebrate faunachron. Dunkard xenacanth selachians support the tetrapod-based correlations. Vertebrate biochronology thus indicates that the Waynesburg and Washington Formations are late Coyotean, whereas the Greene Formation is Seymouran. Therefore, vertebrate biostratigraphy and biochronology indicate that the entire Dunkard Group is Early Permian and likely straddles the Wolfcampian-Leonardian boundary.

On this microcontinent vegetation represented the Cathaysian floral realm that had taxa in common with the tropical Euramerican floral realm, but was characterized by endemic taxa and those that had already become extirpated in Euramerica. Large parts of the North China microcontinent were covered by a cratonic basin in which marine, paralic, and entirely terrestrial beds were deposited that have been described as the Taiyuan Formation. Floras from the Taiyuan Formation indicate that this formation is time transgressive. Abstract Copyright (2013) Elsevier, B.V.

These are the youngest Paleozoic rocks in the Illinois basin and are approximately 550 and 750km, respectively, from strata of comparable age in the Dunkard Basin and Midcontinent. A continuous core, Gil 30, was drilled in the eastern (Cap Mauzy) outlier. Fusulinids (Leptotriticies beardi) from a depth of 59.4m were originally used as evidence for Permian age, although this species is now considered to be latest Pennsylvanian. Ostracods from above the fusulinids support a Permian age. The upper 103.6m of Gil 30 is assigned to the Mauzy Formation and contains intervals of bedded, micritic, nodular to brecciated limestone of probable lacustrine origin, alternating with marine to brackish-water clastic intervals that tend to coarsen upward, a single upward-fining sandstone interval, and a single 2cm thick coal layer. Older strata contain much more coal and almost no bedded non-marine limestone. The Grove Center graben, 18km west of Gil 30, is identified on the basis of an oil-test hole electric log and coal test holes. No core samples are available, but log comparison indicates that the Grove Center outlier contains at least an additional 67m of younger strata than Gil 30, and is a prime target for further study. Regional coalification and oil-maturation trends, along with lack of evidence for syndepositional tectonic activity in Gil 30, indicate that the Permian rocks preserved in Gil 30, and by extension the Grove Center Graben, are likely representative of strata that once occupied much of the Illinois Basin, probably in continuity with the Midcontinent. The Kentucky outliers, therefore, provide a link between the Midcontinent and Dunkard basins and may be important in addressing long-standing problems, such as the age of the Dunkard, and paleoclimate reconstructions.

Geologic investigation and mapping of the Dunkard Group began with the First Pennsylvania Geological Survey in the 1830s, but poor exposure, exposure of only limited stratigraphic intervals, and lack of significant economic commodities have hampered stratigraphic studies. Maximum thicknesses in excess of 335m (1100ft) are found beneath the highest ridges along the synclinorium axis near Wileyville, West Virginia and Windy Gap, Pennsylvania and the stratigraphic correlation of these sites is shown with composite sections constructed from core records and measured sections. Distinct facies provinces are documented in the Dunkard Group, from south to north interpreted as (1) upper fluvial plain, (2) lower fluvial plain, and (3) fluvial-lacustrine deltaic plain. This spatial array of facies provinces is illustrated by a cross section through Dunkard Group and underlying Monongahela Group strata based on drillers' and geologists' core logs. Strata in the upper fluvial plain are cyclic sequences of red, green, and gray, nonfissile mudstone and claystone paleosols exhibiting vertic features, red, green and gray fissile shale, and gray and green sandstone. Coal and limestone are rare, although abundant calcareous material is present as nodules and cement. In contrast, the fluvial-lacustrine deltaic plain cycles are comprised of coal and nonmarine limestone, fewer fluvial shale and sandstone units, and only rare redbeds. The lower fluvial plain cycles exhibit a transition between the other two provinces, containing coal and nonmarine limestone, as well as significant fluvial units and redbeds. Coal beds in the Dunkard Group are best developed in the fluvial-lacustrine deltaic plain but are generally thin and low in quality. Stratigraphically extensive, laterally continuous road cuts and numerous subsurface exploration records, particularly long continuous cores targeting coal beds beneath the Dunkard Group, now aid in better understanding the stratigraphy of the Dunkard Group and will aid in future investigations of these rocks.

This section, with the Pennsylvanian-Permian Boundary firmly established in the Red Eagle Formation on the basis of conodonts, permitted study of vegetational change across the boundary interval. The palynology of 43 productive samples from five cores in Kay and Osage counties in Oklahoma was investigated. Palynomorphs were assigned to eight morphologic groups that also reflect climate preferences. Four distinct palynofloras are recognized. The three transitions between them-in the lower Council Grove, middle Chase and lower Sumner groups-are abrupt and, in succession, consistent with an interpretation of increasing seasonality/aridity from latest Pennsylvanian into the Early Permian. None of these floristic transitions align with the conodont-based boundary, or with any lithostratigraphic "group" boundary. These palynological data from Oklahoma are in accord with previous data from Kansas that also demonstrated no palynological shift at the boundary and increased seasonality/aridity through this period. Comparison of the palynofloras from Oklahoma, Kansas, and the boundary interval of the Pennsylvanian-Permian Boundary type section in Aidaralash Creek in Kazakhstan reveals differences in composition that suggest local to regional, including climatically induced, heterogeneities that may present an obstacle to confident palynologically based, global correlations in fully terrestrial sections.

Petrographically, Dunkard coals are high in vitrinite (avg. 83.1%, mmf), with correspondingly low to moderate amounts of liptinite (avg. 2.1%, mmf) and inertinite (avg. 13.8%, mmf). Palynologically, Dunkard coal beds are all dominated by tree fern spore taxa (avg. 96.3%), especially Punctatisporites minutus (avg. 82.8%). Calamite spores are the second most abundant plant group (avg. 2.4%), with others (lycopods, small ferns, Cordaites and other gymnosperms) having very minor representation. Overall, the coal palynofloras are strongly dominated by lowland plants (ferns and Calamites), with only rare occurrences of bisaccate-striate conifer pollen. Coal beds of the underlying Monongahela Group (Pittsburgh, Redstone, Sewickley and Waynesburg) are thicker (avg. 1.6m), and are lower in ash (avg. 13.4%) and sulfur (avg. 3.3%) than their Dunkard counterparts. Petrographically, Monongahela Group coals are very similar to Dunkard Group coals, when compared on a mineral matter free basis; coal beds that occur in both groups are strongly dominated by vitrinite macerals. Monongahela Group coals are also palynologically very similar to Dunkard Group coals, with tree fern spore taxa dominating. A coal bed of Early Permian age from west-central Texas is also similar, petrographically and palynologically, to Dunkard and Monongahela coals, being vitrinite and tree fern spore dominant. The almost complete lack of coniferous pollen in Dunkard coals led earlier workers to conclude that the Dunkard was entirely Late Pennsylvanian, and not Permian, in age. However, it is now known that Late Pennsylvania lowland floras persisted into the Dunkard, especially during wet intervals. As earlier interpretations were based primarily on spore and pollen floras from coal beds, the lack of conifer pollen in Dunkard coals is probably the result of a sampling bias. Because of this ecological bias, coal palynology is a poor proxy for age dating Dunkard Group coals. Collectively, Dunkard swamps were all planar and topogenous, their formation being controlled by topography and moisture availability. A progressive decrease in wet intervals, both in terms of frequency and duration, during the Dunkard was the major control on peat accumulation and preservation. Collectively, moisture limitation appears to be the principle factor that controlled the formation of Dunkard Group coals. Abstract Copyright (2013) Elsevier, B.V.

These predominantly monotonous fluvial red beds intercalate with laterally widespread grey to variegated sediments of dominantly lacustrine origin. Both, fossil and climatic records show that apart from a generally known long-term climatic shift to drier conditions in Early Permian, the climate oscillated on several time scales throughout the study interval. Climatic indicators in the red beds part of the succession include paleosols ranging between red vertisols and vertic calcisols suggesting strongly seasonal dry sub-humid climate. This is in agreement with the rarity of plant remains, which were mostly completely oxidized and only rarely preserved as plant impression in red mudstones or as silicified mostly gymnosperm woods in sandy channel fills. Silicification instead of coalification was the dominant fossilization process during red-beds deposition. Even drier, possibly semi-arid climate may be indicated by spatially and temporarily restricted bimodal sandstones, dominated by well-rounded quartz grains and interpreted as eolian in origin. Periods of moist sub-humid (or even humid) climate were accompanied by formation of perennial lakes containing gray laminated mudstones, dark grey bituminous mudstones or limestones, muddy limestones, chert layers or even spatially restricted coals, some of them, however, of economic importance. Shorter climatic oscillations operating on a scale of tens to possibly hundreds of thousands of years are represented by transgressive-regressive lacustrine cycles followed by significant changes in lake water salinity reflected by boron content. The fossil record indicates the presence of dryland and wetland biomes in basinal lowlands although their proportions varied significantly as the climate changed. During deposition of red beds, the alluvial plain was vegetated dominantly by dryland biome assemblages. The composition of these assemblages is indicated by fairly common silicified gymnosperm (cordaitalean and coniferous) woods in sandstone-conglomerate fluvial channel bedforms and by poorly preserved impressions of walchian conifer shoots and cordaitalean leaves in associated mudstone intercalations. This is in agreement with sub-vertical root rhizolites and haloes in calcic vertisols. Occurrence of "wet spots" colonized by wetland assemblages is indicated by rather exceptional findings of silicified calamite stems in fluvial red beds associated with gymnospermous woods. During the humid intervals parts of the basinal lowlands were occupied by lakes surrounded by broad belts of wetland biome floras. During the "Stephanian C" most of these floras were dominated by tree ferns, calamites and sub-dominant pteridosperms. Local peat swamps were colonized by lycopsids including Sigillaria brardii, Asolanus camptotaenia and even some lepidodendrid lycopsids. In contrast, the fossil record of "Stephanian C" dryland floras is rarely preserved in lacustrine sediments. The fossil record of "Autunian" lakes, however, suggests increasing proportions of dryland elements, including conifers and peltasperms. The response of lacustrine faunas to climatic oscillations around the Carboniferous-Permian transition is less prominent than that of plants. The origin of the transition between the local Elonichthys-Sphaerolepis and Acanthodes gracilis bio/ecozones around the Carboniferous/Permian boundary is impossible to deduce from the existing fossil record.

This wing originates from the Cassville Shale in the Waynesburg Formation, at the very base of the Dunkard Group. S. balteata is a zone species of a late Paleozoic spiloblattinid insect zonation that is calibrated by the co-occurrence of spiloblattinid zone species with conodont- and fusulinid-zone species in Kasimovian to Early Asselian mixed marine-continental profiles of New Mexico, USA, and the Donets basin in the Ukraine, as well as by the isotopic ages of volcanic intrusions into the Late Stephanian (Gzhelian) strata of the Saale Basin in Germany. The base of the zone underlying the S. balteata Zone is defined by the FAD of Sysciophlebia ilfeldensis in the late Gzhelian, and has an upper limit (LAD) of early to middle Asselian. An early or middle Asselian to earliest Sakmarian range of both the subzones of the S. balteata Zone can be inferred. Given that the mean duration of a spiloblattinid insect zone is about 1.5 to 2Ma, the upper limit of the S. balteata Zone is early Sakmarian. Hence, the base of the Dunkard Group should be maximally of early Asselian or minimally of earliest Sakmarian age. Abstract Copyright (2013) Elsevier, B.V.

In anthropology, this interest was especially prevalent among cultural ecologists of the 1970s and earlier, who tended to explain culture as the result of techno-environmental constraints. More recently researchers have used historical ecology, an approach that focuses on the long-term dialectical relationship between humans and their environments, as well as long-term prehuman ecological datasets. An important contribution of anthropology to historical ecology is that anthropological datasets dealing with ethnohistory, traditional ecological knowledge, and human skeletal analysis, as well as archeological datasets on faunal and floral remains, artifacts, geochemistry, and stratigraphic analysis, provide a deep time perspective (across decades, centuries, and millennia) on the evolution of ecosystems and the place of people in those larger systems. Historical ecological data also have an applied component that can provide important information on the relative abundances of flora and fauna, changes in biogeography, alternations in food webs, landscape evolution, and much more.

The older Caisan debris avalanche deposit is at or beyond the radiocarbon dating range, >43,500 yr B.P., whereas the younger Barriles debris avalanche deposit is constrained by two radiocarbon ages that are ca. 9000 yr B.P. The total runout length of the Caisan deposit was approximately 50 km, covering nearly 1200 km (super 2) . The Barriles deposit extended to approximately 45 km and covered >990 km (super 2) , overlapping most of the Caisan. Over 4000 hummocks from these deposits were digitized, and statistical analysis of hummock location and geometry depicts flow patterns of highly fragmented material affected by underlying topography and also helps to define the shorter runout limit of the Barriles deposit. The Barriles and Caisan deposits are primarily unconfined deposits that are among the world's most voluminous subaerial debris avalanche deposits. Two different geospatial procedures, utilizing deposit thicknesses and edifice reconstruction, yield calculated volumes approximately 30 km (super 3) and larger for both deposits. Subaerial deposits of comparable scale include those from Mount Shasta, Socompa, and Shiveluch. Currently, the modern edifice is 200-400 m lower than the estimated precollapse Barriles and Caisan summits, and only 16%-25% of the former edifice has been replaced since the last failure. The approximately 10 km (super 3) postcollapse lava-dome complex, however, implies a Holocene magma production rate of 1.1 km (super 3) /k.y., comparable to elevated eruptive pulses documented at other stratovolcanoes, underscoring the importance of hazards assessment and monitoring of this active volcano.

Field observations, supplemented by experimental and numerical constraints on wind characteristics and aeolian transport, reveal their conditions of formation and growth to be an aeolian geomorphology "perfect storm." The bedforms are formed on a substrate of weakly indurated ignimbrite, aeolian deflation of which yields a bimodal lag of lithics and pumice clasts onto an undulating surface. Under normal wind conditions in this region, the lithics are organized into bedforms on local upslopes and "highs" through creep induced by the impact of saltating sand and pumice. The gravel bedforms grow through "shadowing" and trap sand and silt that is gradually kinetically sieved down to "lift" the gravel mantle upwards to form the megaripples. These observations connote that the largest features are not ripples in the sense of migrating bedforms, but rather nucleation sites of wind-transported sediment. Strong control by bedrock topography means that the largest bedform wavelengths are not a result of particle trajectories, and this complicates their comparison with other ripples and may require a new classification. Of relevance to Mars, the Puna megaripples are morphologically and contextually similar to small ripple-like transverse aeolian ridges (TARs). Moreover, the Puna gravels have similar equivalent weight (mg) to those composing granule ripples at Meridiani Planum, and their local origin may have implications for the origin of sediment in martian aeolian bedforms. Finally, the stable yet dynamic character of the Puna megaripples could help reconcile current models of TARs with periodic bedrock ridges that may be produced by aeolian erosion.

AN - 1464512307; 18811010 AB - Plant biodiversity in the tropics is threatened by intense anthropogenic pressures. Deforestation, habitat degradation, habitat fragmentation, overexploitation, invasive species, pollution, global climate change, and the synergies among them have had a major impact on biodiversity. This review paper provides a brief, yet comprehensive and broad, overview of the main threats to tropical plant biodiversity and how they differ from threats in temperate regions. The Global Strategy for Plant Conservation, an international program with 16 global targets set for 2020 aimed at understanding, conserving, and using sustainably the world's plant biodiversity, is then used as a framework to explore efforts in assessing and managing tropical plant conservation in a changing world. Progress on 13 of the 16 outcome-oriented targets of the Strategy is explored at the pantropical scale. Within each target, I address current challenges in assessing and managing tropical plant biodiversity, identify key questions that should be addressed, and suggest ways for how these challenges might be overcome.Original Abstract: Resumen La biodiversidad vegetal en los tropicos se encuentra amenazada debido a la intensa actividad humana. La deforestacion, la degradacion y fragmentacion de los habitats, la sobre explotacion de recursos, las especies invasivas, la contaminacion, el cambio climatico global y la interaccion entre estos tienen un gran impacto sobre la biodiversidad. El presente articulo provee un resumen, aunque corto, exhaustivo y amplio en identificar las principales amenazas a la biodiversidad tropical y como estas difieren de las amenazas en las regiones templadas. La Estrategia de Conservacion Global de Plantas, un programa internacional con 16 metas globales trazadas para el ano 2020, cuyo objetivo es el de entender, conservar y utilizar de manera sostenible la biodiversidad vegetal del planeta, es utilizado como marco exploratorio en los esfuerzos de asesar y manejar la conservacion vegetal tropical en un mundo cambiante. El progreso de 13 des 16 metas es analizado a nivel de escala pantropical. Dentro de cada uno de estas metas, los retos actuales son abordados para asesar y manejar biodiversidad vegetal tropical, para de esta manera identificar las inquietudes a ser atendidas y para sugerir soluciones a estas.

Dissected adipose tissue from wild toque macaques (Macaca sinica) (WTM), feeding on a natural diet, accounted for 2.1% of body weight. This was far less than fatness reported for nonhuman primates raised in captivity or for contemporary humans. In WTM, fatness increased with age and diet richness, but did not differ by sex. In WTM (none of which were obese) intra-abdominal fat filled first, and “ ;excess' fat was stored peripherally in a ratio of about 6:1. Intermuscular fat was minimal (0.1%). The superficial paunch held <15% of subcutaneous fat weight in contrast to its much larger proportions in obese humans and captive monkeys where most added fat accumulates subcutaneously. With increasing total adiposity, accumulating fat shifted in its distribution among eight different main internal and peripheral deposit areas-consistent with maintaining body balance and a low center of gravity. The available data suggest that, in arboreal primates, adaptations for agile locomotion and terminal branch feeding set constraints on the quantity and distribution of fat. The absence of a higher percentage of body fat in females and neonates (as are typical of humans) suggests that arboreal adaptations preclude the development of fat-dependent, large-brained infants and the adipose-rich mothers needed to sustain them. The lifestyle and body composition of wild primates represent a more appropriate model for early human foragers than well-fed captive monkeys do.

Despite these efforts, there are relatively few data comparing net ecosystem exchange of CO sub(2) between the atmosphere and the biosphere ( NEE ), under both ambient and elevated C sub(a). Here we report data on annual sums of CO sub(2) ( NEE sub(net) ) for 19 years on a Chesapeake Bay tidal wetland for S cirpus olneyi (C sub(3) photosynthetic pathway)- and Spartina patens (C sub(4) photosynthetic pathway)-dominated high marsh communities exposed to ambient and elevated C sub(a) (ambient + 340 ppm). Our objectives were to (i) quantify effects of elevated C sub(a) on seasonally integrated CO sub(2) assimilation ( NEE sub(net) = NEE sub(day) + NEE sub(night) , kg C m super(-2) y super(-1)) for the two communities; and (ii) quantify effects of altered canopy N content on ecosystem photosynthesis and respiration. Across all years, NEE sub(net) averaged 1.9 kg m super(-2) y super(-1) in ambient C sub(a) and 2.5 kg m super(-2) y super(-1) in elevated C sub(a), for the C sub(3)-dominated community. Similarly, elevated C sub(a) significantly (P < 0.01) increased carbon uptake in the C sub(4)-dominated community, as NEE sub(net) averaged 1.5 kg m super(-2) y super(-1) in ambient C sub(a) and 1.7 kg m super(-2) y super(-1) in elevated C sub(a). This resulted in an average CO sub(2) stimulation of 32% and 13% of seasonally integrated NEE sub(net) for the C sub(3)- and C sub(4)-dominated communities, respectively. Increased NEE sub(day) was correlated with increased efficiencies of light and nitrogen use for net carbon assimilation under elevated C sub(a), while decreased NEE sub(night) was associated with lower canopy nitrogen content. These results suggest that rising C sub(a) may increase carbon assimilation in both C sub(3)- and C sub(4)-dominated wetland communities. The challenge remains to identify the fate of the assimilated carbon.

Amphibians are also increasingly endangered, due in part to disease-driven threats of extinctions. As an emergency response, conservationists have begun ex situ assurance colonies for priority species. The abundance of cryptic amphibian diversity, however, may cause problems for ex situ conservation. In this study we used a DNA barcoding approach to survey mitochondrial DNA (mtDNA) variation in captive populations of 10 species of Neotropical amphibians maintained in an ex situ assurance programme at El Valle Amphibian Conservation Center (EVACC) in the Republic of Panama. We combined these mtDNA sequences with genetic data from presumably conspecific wild populations sampled from across Panama, and applied genetic distance-based and character-based analyses to identify cryptic lineages. We found that three of ten species harboured substantial cryptic genetic diversity within EVACC, and an additional three species harboured cryptic diversity among wild populations, but not in captivity. Ex situ conservation efforts focused on amphibians are therefore vulnerable to an incomplete taxonomy leading to misidentification among cryptic species. DNA barcoding may therefore provide a simple, standardized protocol to identify cryptic diversity readily applicable to any amphibian community.

Mangrove forests, which occur across a broad biogeographic range from warm temperate to tropical, provide a unique opportunity to test these hypotheses by investigating the responses of herbivores to nutrient enrichment in temperate versus tropical latitudes. Mangroves are complex intertidal ecosystems with spatial differences in structure and diversity along tidal gradients and are threatened globally by human activities including nutrient over-enrichment. In this study, we used long-term fertilization experiments at the Indian River Lagoon, FL; Twin Cays, Belize; and Bocas del Toro, Panama to determine how increased nutrients impact herbivore abundance and herbivory of Rhizophora mangle at the tree, forest, and regional scales. At these locations, which span approximately 2185 km and 18.4 super(o) of latitude, we fertilized individual trees with one of three treatments (Control, +N, +P) in two zones (fringe, scrub) along transects perpendicular to the shoreline and measured their responses for 4 years. Herbivory was measured as folivory, loss of yield, and tissue mining. Although nutrient enrichment altered plant growth, leaf traits, and nutrient dynamics, these variables had little effect on folivory at any location. Our results did not support the prediction that herbivory and per capita consumption are greatest at the most tropical location. Instead, folivory was highest at the most temperate location and lowest at the intermediate location. Folivory was generally higher in the fringe than in the scrub zone, but the pattern varied by location, herbivore, and nutrient treatment. Folivory by a dominant herbivore, Aratus pisonii, decreased from the highest to the lowest latitude.

2013-091135 AB - Paleosols in the Bogota Basin, Colombia, record an increase in chemical weathering across the Paleocene-Eocene (P-E) transition. Rock magnetic properties and major element geochemistry exhibit an abrupt change in an interval identified as including the P-E boundary, as established by previously published biostratigraphy and a U/Pb date on volcanic zircons (56.2+ or -1.6 Ma). During the stratigraphic interval that contains the P-E transition, magnetic susceptibility increases significantly, with an order of magnitude higher concentration of magnetite/maghemite and hematite. The preponderance of pure stoichiometric magnetite in the paleosols of this interval indicates that the increase in magnetic susceptibility is due to changes in the rate of pedogenesis, rather than an increase in the erosion of nearby volcanic rocks, which would contribute titanomagnetite. Pedogenic structures preserved within the paleosols, a lack of iron oxides as cement, friability of the sandstones, and previously published thermochronologic data are not consistent with burial diagenesis as an explanation for the origin of the magnetic mineral assemblage. These enhanced pedogenesis and related chemical weathering is also confirmed by increases in the concentration of Fe (sub 2) O (sub 3) and Al (sub 2) O (sub 3) and loss on ignition values. An increase in mean precipitation across this interval is inferred by the lack of carbonate nodules and a decrease in SiO (sub 2) in paleosols. Thus, we hypothesize that there was an intensification of chemical weathering during the interval that contains the P-E transition. Abstract Copyright (2013) Elsevier, B.V.

AN - 1443410037; 24024607 AB - Microbial mercury (Hg) methylation transforms a toxic trace metal into the highly bioaccumulated neurotoxin methylmercury (MeHg). The lack of a genetic marker for microbial MeHg production has prevented a clear understanding of Hg-methylating organism distribution in nature. Recently, a specific gene cluster (hgcAB) was linked to Hg methylation in two bacteria.1 Here we test if the presence of hgcAB orthologues is a reliable predictor of Hg methylation capability in microorganisms, a necessary confirmation for the development of molecular probes for Hg-methylation in nature. Although hgcAB orthologues are rare among all available microbial genomes, organisms are much more phylogenetically and environmentally diverse than previously thought. By directly measuring MeHg production in several bacterial and archaeal strains encoding hgcAB, we confirmed that possessing hgcAB predicts Hg methylation capability. For the first time, we demonstrated Hg methylation in a number of species other than sulfate- (SRB) and iron- (FeRB) reducing bacteria, including methanogens, and syntrophic, acetogenic, and fermentative Firmicutes. Several of these species occupy novel environmental niches for Hg methylation, including methanogenic habitats such as rice paddies, the animal gut, and extremes of pH and salinity. Identification of these organisms as Hg methylators now links methylation to discrete gene markers in microbial communities.

We explore these properties motivated by two key questions: whether such planets could provide habitable conditions and whether they exhibit discernable spectral features that distinguish a water-planet from a rocky Earth-like planet. We show that the recently discovered planets Kepler-62e and -62f are the first viable candidates for habitable zone water-planets. We use these planets as test cases for discussing those differences in detail. We generate atmospheric spectral models and find that potentially habitable water-planets show a distinctive spectral fingerprint in transit depending on their position in the habitable zone.

We find that the majority of closely spaced stable two-planet systems can stably support satellites across a range of parameter-space which is only slightly decreased compared to that seen for the single-planet case. In particular, circular prograde satellites remain stable out to approximately 0.4 R (sub H) (where R (sub H) is the Hill radius) as opposed to 0.5 R (sub H) in the single-planet case. A similarly small restriction in the stable parameter-space for retrograde satellites is observed, where planetary close approaches in the range 2.5-4.5 mutual Hill radii destabilize most satellites orbits only if a approximately 0.65 R (sub H) . In very close planetary pairs (e.g., the 12:11 resonance) the addition of a satellite frequently destabilizes the entire system, causing extreme close approaches and the loss of satellites over a range of circumplanetary semi-major axes. The majority of systems investigated stably harbored satellites over a wide parameter-space, suggesting that STIPs can generally offer a dynamically stable home for satellites, albeit with a slightly smaller stable parameter-space than the single-planet case. As we demonstrate that multi-planet systems are not a priori poor candidates for hosting satellites, future measurements of satellite occurrence rates in multi-planet systems versus single-planet systems could be used to constrain either satellite formation or past periods of strong dynamical interaction between planets.

The properties of such Population III (Pop III) stars are thought to be very different than those of later stellar generations, because cooling is dramatically different in gas with a metallicity below a critical value Z sub(c), which lies between ~10 super(-6) and ~10 super(-3) Z sub([middot in circle]). The critical value is much smaller than the typical overall average metallicity, [left angle bracket] Z [right angle bracket], and therefore the mixing efficiency of the pristine gas in the interstellar medium plays a crucial role in determining the transition from Pop III to normal star formation. The small critical value, Z sub(c), corresponds to the far left tail of the probability distribution function (PDF) of the metal abundance. Based on closure models for the PDF formulation of turbulent mixing, we derive evolution equations for the fraction of gas, P, lying below Z sub(c), in statistically homogeneous compressible turbulence. Our simulation data show that the evolution of the pristine fraction P can be well approximated by a generalized "self-convolution" model, which predicts that P = -(n/[tau] sub(con))P(1 - P super(1)/n), where n is a measure of the locality of the mixing or PDF convolution events and the convolution timescale [tau] sub(con) is determined by the rate at which turbulence stretches the pollutants. Carrying out a suite of numerical simulations with turbulent Mach numbers ranging from M = 0.9 to 6.2, we are able to provide accurate fits to n and [tau] sub(con) as a function of M, Z sub(c)/[left angle bracket] Z [righe angle bracket], and the length scale, L sub(p), at which pollutants are added to the flow. For pristine fractions above P = 0.9, mixing occurs only in the regions surrounding blobs of pollutants, such that n = 1. For smaller values of P, n is larger as the mixing process becomes more global. We show how these results can be used to construct one-zone models for the evolution of Pop III stars in a single high-redshift galaxy, as well as subgrid models for tracking the evolution of the first stars in large cosmological numerical simulations.

Upon confirmation that Sigal's Madagascan holotype was actually from the upper Albian, this species was renamed as T. eubejaouaensis Randrianasolo and Anglada, 1998 using Sigal's Tunisian bejaouaensis paratype, which is late Aptian in age, as the new holotype. Following emendation of the genus, Paraticinella eubejaouaensis has recently become the standard usage. However, the validity of this species is still uncertain because the original designation was given in very obscure publication(s). Meanwhile, albeit tenuous, a presumable senior name "Paraticinella rohri (Bolli, 1959)" has recently been proposed in place of eubejaouaensis. Rigorous assessment of the original species designation of T. eubejaouaensis ascertains that the method of publication used does not comply with the criteria required in the International Code of Zoological Nomenclature, thereby making this species an invalid name, or nomen nudum. New backscattered scanning electron microscopic observations of the primary types of Praeglobotruncana rohri Bolli, 1959 reveal that this hitherto unattended species is indeed synonymous to "T. eubejaouaensis" particularly by exhibiting equatorially aligned rugosities on the wall surface, and that the holotype is sufficiently preserved and well qualified as the name-bearing type. The latest Aptian age of the rohri type level is robustly established by its co-occurrence with Pseudoplanomalina cheniourensis (Sigal, 1952) and Hedbergella trocoidea (Gandolfi, 1942) (= another rohri paratype). Upon confirmation of the absence of any potential nomenclatural acts for conservation of the junior name "[eu]bejaouaensis," we are obliged to provide formal redescription and establish the valid, objective senior name Paraticinella rohri (Bolli, 1959), the binomen that should be of mandatory use henceforth. Accordingly, the uppermost Aptian "[eu]bejaouaensis" Zone should be referred to as the "Pt. rohri Zone." Having reviewed the supraspecific taxonomy, herein the type species of the genus Paraticinella is redefined as Pt. rohri, and the subfamily Pseudoplanomalininae is proposed.

Displacement profiles and displacement-to-length scaling both indicate that faults near the basin center are confined to a nearly equal 4-km-thick mechanical layer, whereas faults far from the center penetrate more deeply. The fault scaling also indicates that the graben formed in mechanically strong material, which we identify with dry basalt-like plains. These plains were also affected by changes in long-wavelength topography, including undulations with wavelengths of up to 1300 km and amplitudes of 2.5 to 3 km. Geographic correlation of the depth extent of faulting with topographic variations allows a first-order interpretation of the subsurface structure and mechanical stratigraphy in the basin. Further, crosscutting and superposition relationships among plains, faults, craters, and topography indicate that development of long-wavelength topographic variations followed plains emplacement, faulting, and much of the cratering within the Caloris basin. As several examples of these topographic undulations are also found outside the basin, our results on the scale, structural style, and relative timing of the topographic changes have regional applicability and may be the surface expression of global-scale interior processes on Mercury.

An Update on the Automatic/Systematic Declassification Review Program AN - 1512200503; 201403845 AB - Executive Order (E.O.) 12958, signed by President William Clinton in April 1995, established an unprecedented declassification procedure designed to release quickly massive numbers of executive branch records dating back to World War II. The program encountered numerous problems, however, and subsequent executive orders pushed back deadlines and created new grounds to exempt records from its operation. Relatively few high-level records have been released and made available to the public. However, modifications to the program made by E.O. 13526 in 2009 and changes proposed by the Public Interest Declassification Board in 2012 will make important progress in reversing this situation.

How do market and agricultural policies and development interventions impact on both agricultural and social change, and consequently on food self-sufficiency? Which long-term factors can contribute to 'depeasantization'? Is the 'New Green Revolution' the best and only solution for African food insecurity? These are the main questions this paper sets out to address, using southern Guinea-Bissau as a case study. On the basis of long-term ethnographic fieldwork, we look at farmers' responses to external and internal pressures, and analyse how 'depeasantization' progresses and livelihoods have been losing their resilience. Chances to reverse this trend, although difficult to implement, may still be feasible. Adapted from the source document.

There are both gastropod and bivalve families that are each primarily dioecious, simultaneous hermaphrodites, or sequential hermaphrodites, and other families in which almost every sexual strategy occurs. The multiple evolutionary transitions of sexual systems within molluscs would allow comparative analyses of the associated ecological factors, but data on all but a few groups are too sparse to draw many solid conclusions. The phylogenetic distribution of sexual systems in the Mollusca shows that gastropods and bivalves demonstrate different patterns, possibly associated with the presence/absence of copulation. The distribution of change of sex suggests that, in gastropods, sequential hermaphrodites do not evolve from simultaneous hermaphrodites, and that sex reversal (flip-flopping) occurs in free-spawners but not in copulators. Three well-studied protandrous gastropod groups (calyptraeids, coralliophilids, and patellogastropods) show similar responses to environmental conditions and associations with conspecifics. They all have the following attributes: (1) they are sedentary, (2) they live in groups, patches, or aggregates, and (3) size at sex change varies among sites and among aggregates. In addition the available experimental evidence suggests that (4) the presence of females or large individuals represses growth and sex change of males, and (5) behavior seems to mediate the repressive influence of large females. Available data from other species tend to support these patterns. Finally, the repression of growth of males by females in protandry likely facilitates the evolution of dwarf males.

While theoretically settled long ago as being different aspects of coal systems science, the two concepts are still often confounded. In recent years, this has resulted in the publication of several works stating that coal type changes with coal rank. Coal type refers solely to coals' depositional origin and the maceral-mineral admixture resulting from that origin. Coal types typically fall in to two categories: humic coals, developed from peat, and sapropelic coals, developed from organic mud. Either type may be allocthonous or autochthonous, and within types, further refinement of depositional environment can be made. Coal rank refers to the changes in geochemistry and resultant changes in reflectance caused by increasing thermal maturity of the coal. Thus, it provides an overprint of maturity on existing coal types. With proper techniques, such as use of crossed polars and etching, maceral forms can be differentiated even at high ranks, and the original coal type determined.

Two experiments were undertaken. In the first experiment, serpentine was obtained by hydrating terrestrial olivine (Fo (sub 90.9) ) in the laboratory. During this experiment, olivine was reacted with isotopically heavy water (delta (super 18) O 21.5 ppm) at T = 300 degrees C, P (sub H2O) = 300 bar, for 100 days. The oxygen isotopic composition of the experimental serpentine was enriched in (super 18) O (by 10 ppm in delta (super 18) O) due to exchange of oxygen isotopes between olivine and the (super 18) O-rich water. Dehydrated serpentine was then produced during laboratory heating experiment in vacuum, at T = 930 degrees C, for 1 h. The oxygen isotopic composition of the dehydrated serpentine was enriched in (super 18) O by a further 7 ppm. The net result of the hydration-dehydration process was an enrichment of (super 18) O in the final material by approximately 17 ppm. The new experimental results suggest that the oxygen isotopic compositions of MCCs of the Belgica-like group, including Dhofar 225 and Dhofar 725, could be derived from those of typical CM2 chondrites via several cycles of hydration-dehydration caused by aqueous alteration and subsequent thermal metamorphism within their parent asteroids.

This compromises international conservation efforts and requires urgent attention from the world's maritime industry. Humpback whales (Megaptera novaeangliae) are at the top of the death toll, and although Central America is a wintering area for populations from both the Northern and Southern Hemispheres, existing efforts to reduce ship-whale collisions are meager. Herein, we evaluated the potential collisions between vessels and humpback whales wintering off Pacific Panama by following the movements of 15 whales tagged with satellite transmitters and comparing these data with tracks plotted using AIS real-time latitude-longitude points from nearly 1,000 commercial vessels. Movements of whales (adults and calves) in the Gulf of Panama coincide with major commercial maritime routes. AIS vessel data analyzed for individual whale satellite tracks showed that 53% (8 whales) of whales had 98 encounters within 200 m with 81 different vessels in just 11 d. We suggest implementing a 65 nmi Traffic Separation Scheme and a 10 kn maximum speed for vessel routing into the Gulf of Panama during the wintering season. In so doing, the area for potential whale-vessel collisions could be reduced by 93%.

New discoveries and reevaluation of existing materials leads to the recognition of two new records of the pimelodid Brachyplatystoma cf. vaillantii, and of three distinct doradid taxa: Doraops sp., Rhinodoras sp., and an unidentified third form. The presence of fossil goliath long-whiskered catfishes and thorny catfishes are indicative of the persistence of a fluvial drainage system inflow into the South Caribbean during the Pliocene/Pleistocene boundary, complementary to the previous western Amazonian hydrographic system described from the Middle Miocene Villavieja Formation in central Colombia and Late Miocene Urumaco Formation in northwestern Venezuela. The Pliocene Castilletes and San Gregorio formations potentially represent the last lithostratigraphic units related with an ancient western Amazonian fish fauna and that drainage system in the Caribbean. Alternatively, it may preserve faunas from a smaller, peripheral river basin that was cut off earlier from the Amazon-Orinoco, today found in the Maracaibo basin and the Magdalena Rivers.

With O. woworae, the first described endemic ricefish of Sulawesi Tenggara, they comprise a group of small, colorful species characterized by orange to deep red dorsal and ventral margins of the caudal fin and the ventral margin of the caudal peduncle and at least the posterior portion of the base of the anal fin, and a bluish sheen on the body in both sexes that is most pronounced in live adult males. The two new species are distinguished from O. woworae by elongate middle dorsal-fin rays in adult males that reach the posterior extent of the first principal caudal-fin ray and by an orange-colored olfactory epithelium that marks each nasal organ in females. Oryzias asinua is relatively slender compared to O. wolasi and O. woworae: the body is narrow (21-25% SL, with a mean 22.9, in O. asinua versus 23-32% SL, mean 25.3 in O. wolasi and 22-30% SL, mean 26 in O. woworae). Oryzias asinua has fewer procurrent caudal-fin rays in the lower lobe (4-5 versus 5-7 in O. wolasi and 5-6 in O. woworae). Oryzias wolasi is golden in life in both sexes and relatively deep-bodied, reaching 32% SL, and has a deeper caudal peduncle (11-12% SL, mean 11.2, versus 9-11, mean 10, in O. asinua and 8-11, mean 9.2, in O. woworae). Maximum parsimony and Bayesian inference analyses of the mitochondrial cytochrome c oxidase subunit 1 (COI) sequence, the DNA barcode, support our hypothesis that we sequenced representatives of three species. All species are allopatric. Description of O. asinua and O. wolasi brings the number of valid species in the beloniform family Adrianichthyidae to 35, 17 of which are endemic to Sulawesi. The two new species are just the second and third ricefishes described from the province of Sulawesi Tenggara, a neglected region in exploration and discovery of the freshwater fish fauna of the Indonesian islands of Sulawesi.

Stratigraphically recurrent packages of distinct lithofacies, representing different habitats, contain qualitatively and quantitatively different macrofloras and microfloras. The species pools demonstrate niche conservatism, remaining closely tied to specific habitats, during both short-term cyclic environmental change and a long-term trend of increasing aridity. The deposits examined principally comprise the terrestrial Markley and its approximate marine equivalent, the Harpersville Formation and parts of lower Archer City Formation. Fossiliferous deposits are lens-like, likely representing fill sequences of channels formed during abandonment phases. Palaeosols, represented by blocky mudstones, comprise a large fraction of the deposits. They suggest progressive climate change from minimally seasonal humid to seasonal subhumid to seasonal dry subhumid. Five lithofacies yielded plants: kaolinite-dominated siltstone, organic shale, mudstone beds within organic shale, coarsening upward mudstone-sandstone interbeds and channel sandstone. Both macro- and microflora were examined. Lithofacies proved compositionally distinct, with different patterns of dominance diversity. Organic shales (swamp deposits), mudstone partings (swamp drainages) and coarsening upward mudstone-sandstone interbeds (floodplains) typically contain Pennsylvanian wetland vegetation. Kaolinite-dominated siltstones and (to the extent known) sandstones contain taxa indicative of seasonally dry substrates. Some kaolinite-dominated siltstones and organic shales/coals yielded palynomorphs. Microfloras are more diverse, with greater wetland-dryland overlap than macrofloras. It appears that these two floras were coexistent at times on the regional landscape.

No ferns have been previously described from Laguna del Hunco. We describe and interpret a new species of fossil Osmundaceae based on fertile and sterile pinnae. Methods: The fossil specimens were compared with other extant and fossil Osmundaceae based on living and herbarium material and published descriptions. A morphological matrix based on 29 characters was constructed for 17 living species in Osmundaceae, four species assigned to the fossil genus Todites, and the new fossil species. Phylogenetic analyses were conducted under parsimony using morphology and total evidence matrices. Key Results: Both the new fossil and the Todites species were consistently resolved within the leptopteroid clade of Osmundaceae, and the new species resolved in a clade with the two living Todea species, which are now restricted to Australia, New Guinea, New Zealand, and southern Africa. Conclusions: Todea amissa sp. nov. is the first record of Todea, living or fossil, in South America and only the second fossil record worldwide. The distribution of extant Todea on Gondwanan continents other than South America is broadly shared with other taxa from Laguna del Hunco, further indicating that a large component of this flora represents a Gondwanic biome that is no longer found on the South American continent.

New fossil evidence indicates that the family was already present in India in the Late Cretaceous (Maastrichtian), about 10-15 million years before the tectonic collision of India with Eurasia. Methods: Fruits and seeds were investigated by serial sections and peels of chert from the Deccan Intertrappean beds of central India, and compared anatomically with those of extant genera. Key results: Indovitis chitaleyae gen. et sp. n. is described based on immature fruits bearing four to six seeds, and isolated mature seeds. The seeds possess paired ventral infolds and a dorsal chalaza, features diagnostic of the order Vitales. Characters of chalaza shape, infold morphology, and seed coat anatomy place I. chitaleyae within Vitaceae and favor a phylogenetic position either sister to the Vitis-Ampelocissus clade or sister to the Ampelopsis-Clematicissus-Rhoicissus clade. Conclusions: Presence of the oldest known vitaceous fossils in the latest Cretaceous of India indicates a previously undocumented Gondwanan history and a possible southern hemisphere origin for the Vitales. An "out-of-India" scenario might explain the relatively sudden appearance of diverse Vitaceae in the Late Paleocene and Early Eocene of the Northern Hemisphere.

This trait is most parsimoniously considered a deeply rooted part of our ancestry rather than a recent cultural invention. Our species is the only vertebrate with society memberships of significantly more than 200. We accomplish this by using society-specific labels to identify members, in what I call an anonymous society. I propose that the human brain has evolved to permit not only the close relationships described by the social brain hypothesis, but also, at little mental cost, the anonymous societies within which such alliances are built. The human compulsion to discover or invent labels to 'mark' group memberships may originally have been expressed in hominins as vocally learned greetings only slightly different in function from chimpanzee pant hoots (now known to be society-specific). The weight of evidence suggests that at some point, conceivably early in the hominin line, the distinct groups composed of several bands that were typical of our ancestors came to be distinguished by their members on the basis of multiple labels that were socially acquired in this way, the earliest of which would leave no trace in the archaeological record. Often overlooked as research subjects, these sizable fission-fusion communities, in recent egalitarian hunter-gatherers sometimes 2,000 strong, should consistently be accorded the status of societies, in the same sense that this word is used to describe tribes, chiefdoms, and other cultures arising later in our history. The capacity of hunter-gatherer societies to grow sufficiently populous that not all members necessarily recognize one another would make the transition to larger agricultural societies straightforward. Humans differ from chimpanzees in that societal labels are essential to the maintenance of societies and the processes giving birth to new ones. I propose that anonymous societies of all kinds can expand only so far as their labels can remain sufficiently stable. Adapted from the source document.

Here we investigate the capabilities of GPR to provide useful geologic information in one of the most common geologic settings of planetary surfaces, impact crater ejecta. Three types of ejecta are surveyed with GPR at two wavelengths (400 MHz, 200 MHz) at Meteor Crater, Arizona, with the goal of capturing the GPR signature of the subsurface rock population. In order to "ground truth" the GPR characterization, subsurface rocks are visually counted and measured in preexisting subsurface exposures immediately adjacent to and below the GPR transect. The rock size-frequency distribution from 10 to 50 cm based on visual counts is well described by both power law and exponential functions, the former slightly better, reflecting the control of fragmentation processes during the impact-ejection event. GPR counts are found to overestimate the number of subsurface rocks in the upper meter (by a factor of 2-3x) and underestimate in the second meter of depth (0.6-1.0x), results attributable to the highly scattering nature of blocky ejecta. Overturned ejecta that is fractured yet in which fragments are minimally displaced from their complement fragments produces fewer GPR returns than well-mixed ejecta. The use of two wavelengths and division of results into multiple depth zones provides multiple aspects by which to characterize the ejecta block population.

Although it is usually placed in Metoposauridae, its affinities have remained unknown since its original description because the unique specimen had never been prepared. Preparation and casting of the specimen, which comprises three pieces of a left mandibular ramus, now permits detailed anatomical description of the jaw and assessment of its affinities. Calamops paludosus is a valid taxon of trematosauroid temnospondyls that can be diagnosed by several autapomorphies. It represents one of the geologically youngest known records of long-snouted trematosaurs and the first record of these temnospondyls from the Late Triassic of North America.

We evaluated historical and contemporary gene flow and effective population sizes of leopards in a landscape in central India using noninvasive sampling. Despite the dramatic changes in land-use patterns in this landscape through recent times, we did not detect any signs that the leopard populations have been through a genetic bottleneck, and they appear to have maintained migration-drift equilibrium. We found that historical levels of gene flow (mean m sub(h) = 0.07) were significantly higher than contemporary levels (mean m sub(c) = 0.03), and populations with large effective population sizes (Satpura and Kanha Tiger Reserves) are the larger exporters of migrants at both timescales. The greatest decline in historical versus contemporary gene flow is between pairs of reserves that are currently not connected by forest corridors (i.e., Melghat-Pench m sub(h )- m sub(c )= 0.063; and Kanha-Satpura m sub(h )- m sub(c )= 0.054). We attribute this reduction in gene flow to accelerated fragmentation and habitat alteration in the landscape over the past few centuries, and suggest protection of forest corridors to maintain gene flow in this landscape.

The recovery of pristinely preserved planktonic foraminifera from Santonian-Campanian sequences in southeastern Tanzania allows examination of faunal changes and documentation of species-specific stable isotope (delta (super 13) C and delta (super 18) O) signatures. These isotopic data are ideal for inferring species paleoecological preferences and for tracing major paleoceanographic changes. This study reports the first delta (super 18) O and delta (super 13) C data generated on "glassy" specimens of Marginotruncana coronata, M. undulata, M. marginata, and M. pseudolinneiana and Sigalia carpatica. Additional results from Shatsky Rise (Ocean Drilling Program Leg 198, Hole 1210B) and Exmouth Plateau (ODP Leg 122, Hole 762C) provide geographic control on species habitat preferences and paleoceanographic context. Isotopic analyses suggest that double-keeled species, including Globotruncana bulloides, Contusotruncana fornicata, C. plummerae and probably marginotruncanids, inhabited the surface mixed layer, whereas the biserial Gublerina rajagopalani was a permanent thermocline dweller. Thus, our study confirms recent suggestions that the depth-distribution models based on shell morphology and analogies with modern taxa are not applicable. At all the examined localities, changes in planktonic foraminiferal assemblages are used to define several ecological intervals, each one characterized by a distinctive taxonomic composition and/or increasing/decreasing species diversity. Combined geochemical and paleontological observations suggest that, by the middle-late Campanian, a stratified upper water column developed in Tanzania while less stratified and/or mesotrophic conditions prevailed at Shatsky Rise and Exmouth Plateau.

The plot is in mature secondary mixed deciduous forest 5 km south of Front Royal, Virginia, USA. The initial plot census enumerated 38 932 free-standing living stems and 29 991 living individuals greater than or equal to 1 cm dbh comprising 62 species, 38 genera, and 26 families, along with an additional 1248 dead/missing standing stems, for a total of 40 180 stems. Dominant canopy trees include tulip poplar (Liriodendron tulipifera), hickories (Carya spp.), oaks (Quercus spp.), white ash (Fraxinus americana), and black gum (Nyssa sylvatica). Prominent understory components include spicebush (Lindera benzoin), pawpaw (Asimina triloba), American hornbeam (Carpinus caroliniana), witchhazel (Hamamelis virginiana), and eastern redbud (Cercis canadensis). Few species predominate numerically on the plot; seven species have >1000 individuals (71.3% of the total). Mean stand density was 1179 living individuals/ha, while mean basal area was 34.1 m super(2)/ha. Of the total plot area, 4 ha have had white-tailed deer (Odocoileus virginianus) exclusion since 1990. Woody seedling surveys from 2010-2012 in 354 1-m super(2) plots measured 19 415 seedlings of 47 species, from new germinants up to 1 cm dbh. Community-wide seed rain data from 200 0.5-m super(2) litterfall traps yielded a total of 9197 records from 37 species. Long-term seed data collected from 1986-2011 for Quercus and Carya within the exclosure and two replicate sites are also presented, documenting considerable annual variation in mast production. Dendrochronological data from 492 tree cores suggested the major canopy trees established circa 1900, but scattered trees of several species existed earlier. Large-scale forest dynamics plots employing standardized methodology have a long, rich history in the tropics. Similar plots in the temperate zone have been largely lacking, however. The SCBI plot represents one of the first of its kind in the Smithsonian Global Earth Observatory's recently established network of such plots, complementing its well-known network of tropical forest plots and enabling comparative studies on forest ecology and climate change at the global scale.

Previous studies have tested the TPH primarily by examining temporal correlations between turnover pulses and climatic events. It is rarely possible to dissect such correlations and observe turnover as it is occurring or to predict how different lineages will respond to climate change. Thus, whether climate change drives faunal turnover in the manner predicted by the TPH remains unclear. In this study, we test the underlying mechanics of the TPH using well-dated Quaternary ungulate records from southern Africa's Cape Floristic Region (CFR). Changes in sea level, vegetation, and topographic barriers across glacial-interglacial transitions in southern Africa caused shifts in habitat size and configuration, allowing us to generate specific predictions concerning the responses of ungulates characterized by different feeding habits and habitat preferences. Examples from the CFR show how climatically forced vegetation change and allopatry can drive turnover resulting from extinction and migration. Evidence for speciation is lacking, suggesting either that climate change does not cause speciation in these circumstances or that the evolutionary outcome of turnover is contingent on the nature and rate of climate change. Migrations and extinctions are observed in the CFR fossil record over geologically short time intervals, on the order of Milankovitch-scale climate oscillations. We propose that such climate oscillations could drive a steady and moderate level of faunal turnover over 10 (super 4) -year time scales, which would not be resolved in paleontological records spanning 10 (super 5) years and longer. A turnover pulse, which is a marked increase in turnover relative to previous and subsequent time periods, requires additional, temporally constrained climatic forcing or other processes that could accelerate evolutionary change, perhaps mediated through biotic interactions.

However, even in the absence of concrete evidence for phylogenetic affinity, numerical paleoecological approaches can be effectively used to make inferences about organismal biology, the nature of biotic interactions, and life history. Here, we examine the population structure of three Ediacaran rangeomorph taxa (Fractofusus, Beothukis, and Pectinifrons), and one non-rangeomorph taxon (Thectardis) across five fossil surfaces around the Avalon Peninsula, Newfoundland, through analysis of size-frequency distributions using Bayesian Information Criterion (BIC). Best-supported models resolve communities of all studied Ediacaran taxa at Mistaken Point as single cohorts with wide variance. This result is best explained in terms of a "continuous reproduction" model, whereby Ediacaran organisms reproduce aseasonally, so that multiple size modes are absent from preserved communities. Modern benthic invertebrates (both as a whole and within specific taxonomic groups) in deeper-water settings reproduce both seasonally and aseasonally; distinguishing between biological (i.e., continuous reproductive strategies) and environmental (lack of a seasonal trigger) causes for this pattern is therefore difficult. However, we hypothesize that the observed population structure could reflect the lack of a trigger for reproduction in deepwater settings (i.e., seasonal flux of organic matter), until the explosive appearance of mesozooplankton near the base of the Cambrian.

Approximately 100 specimens from 18 species were examined, ranging in age from the Cretaceous to the present day. Nine new species are described: Pennyella rexi, Pennyella sanfordae, Pennyella liowae, Pennyella schellenbergi, Pennyella majorani, Pennyella iani, Pennyella ayressi, Rugocythereis melonis and Rugocythereis zarikiani. Emended generic concepts of Pennyella and Rugocythereis are proposed, and the palaeobiogeographical distributions of these two genera are discussed.

However, few studies have directly tested the impact of intergroup conflicts in non-human primates. What is the cost of defeat? To address this question, the movements of six neighboring white-faced capuchin (Cebus capucinus) social groups living on Barro Colorado Island, Panama were tracked simultaneously using an Automated Radio Telemetry System (ARTS), for a period of six months. Groups moved 13% (441 m) further on days they lost interactions compared with days they won interactions. To cover these larger distances, they traveled faster, stopped less frequently, and remained active later in the evening. Defeat also caused groups to alter their patterns of space use. Losing groups had straighter travel paths than winning groups, larger net displacements and were more likely to change their sleeping site. These results demonstrate that losing groups pay increased travel costs and suggest that they forage in low-quality areas. They provide some of the first direct evidence that intergroup conflicts have important energetic consequences for members of competitively unsuccessful primate social groups. A better understanding of how intergroup competition impacts patterns of individual fitness is thus needed to clarify the role that this group-level process plays in shaping the evolution of human- and non-human primate behavior.

This is especially true for forests, which represent a majority of global biomass, productivity and biodiversity. Our analysis of 25 forests across the world shows that the relationship of tree species richness to biomass (AGB) and productivity (CWP) changes qualitatively from positive at small spatial grains typical of forest surveys (0.04 ha) to mixed at slightly larger spatial grains (0.25 and 1 ha). This needs to be recognised in forest conservation policy and management.Original Abstract: Editor's Choice JF - Journal of Ecology AU - Chisholm, Ryan A AU - Muller-Landau, Helene C AU - Rahman, Kassim Abdul AU - Bebber, Daniel P AU - Bin, Yue AU - Bohlman, Stephanie A AU - Bourg, Norman A AU - Brinks, Joshua AU - Bunyavejchewin, Sarayudh AU - Butt, Nathalie AU - Cao, Honglin AU - Cao, Min AU - Cardenas, Dairon AU - Chang, Li-Wan AU - Chiang, Jyh-Min AU - Chuyong, George AU - Condit, Richard AU - Dattaraja, Handanakere S AU - Davies, Stuart AU - Duque, Alvaro AU - Fletcher, Christine AU - Gunatilleke, Nimal AU - Gunatilleke, Savitri AU - Hao, Zhanqing AU - Harrison, Rhett D AU - Howe, Robert AU - Hsieh, Chang-Fu AU - Hubbell, Stephen P AU - Itoh, Akira AU - Kenfack, David AU - Kiratiprayoon, Somboon AU - Larson, Andrew J AU - Lian, Juyu AU - Lin, Dunmei AU - Liu, Haifeng AU - Lutz, James A AU - Ma, Keping AU - Malhi, Yadvinder AU - McMahon, Sean AU - McShea, William AU - Meegaskumbura, Madhava AU - Razman, Salim Mohd AU - Morecroft, Michael D AU - Nytch, Christopher J AU - Oliveira, Alexandre AU - Parker, Geoffrey G AU - Pulla, Sandeep AU - Punchi-Manage, Ruwan AU - Romero-Saltos, Hugo AU - Sang, Weiguo AD - et. al.

In this article, we aimed to verify the consistency of morphological characters in calcarean sponges of the well-known non-monophyletic order Clathrinida using a molecular phylogeny. For this we included 50 species, including six type species, currently assigned to eight different genera. A maximum likelihood topology was generated for the nuclear ITS marker using the General Time Reversible model and the bootstrap reliability test. Our topology indicated 10 clathrinid clades that included species with consistent morphological characters. In the present study, we defined nine of these clades as clathrinid genera, including four newly described and two newly diagnosed genera. Recent studies have indicated that not much phylogenetic information may be found in morphology, but our findings contradict this general assertion. Our study confirms the suitability of skeleton and body anastomosis as valid characters in a phylogenetically sound taxonomy for the order. Interestingly, we have also found that, apart from the Calcinea/Calcaronea split and a few minor details, Haeckel's original proposal is remarkably similar to our own, which was based on a molecular phylogeny 140 years later.

A cladistic analysis of morphology supported the monophyly of Cladorhizidae (including Euchelipluma), Guitarridae (excluding Euchelipluma), Isodictyidae, Latrunculiidae, and Podospongiidae but rejected monophyly for Desmacellidae, Esperiopsidae, Hamacanthidae, and Mycalidae. Analyses of partial 16S and partial 28S rRNA datasets combined, as well as that of a complete 18S rDNA dataset, suggest that Mycalina is not monophyletic; Biemnidae is only distantly related to other poecilosclerids; Merlia and Desmacella branch near the base of a diverse Poecilosclerida clade; Mycalidae is monophyletic (excluding Mycale [Anomomycale] titubans in 18S); and Esperiopsidae and Isodictyidae form a clade. Analyses of the two molecular datasets differed on the monophyly of Podospongiidae and about the relationship of Podospongiidae to Isodictyidae + Esperiopsidae.

Cittarium is so far known only from deposits of interglacial ages corresponding to marine isotope stages (MIS) 11, 9, 5e, and 1 (Holocene). In at least the cases of MIS 11 and 5e, Cittarium appears at the very beginning of the interglacial. The species is definitely absent from well-stratified cave deposits of the last glacial (MIS 4-2). It is hypothesized that colder sea-surface temperatures (SSTs) during glacial periods caused Cittarium to be extirpated on Bermuda, and that it has made at least four independent colonizations of the island in the past 400 000 years. Because of the limited larval life of Cittarium, the window for colonization may be a very narrow period at the onset of interglacials when the SST has risen sufficiently to make Bermuda habitable but the velocity of the Gulf Stream is still sufficiently rapid to transport viable larvae from the Bahamas.

However, most knowledge of plant-herbivore associations is derived from observations of adults. One reason for this bias is that species identification of immature stages is usually challenging. DNA barcodes can be used to identify immature stages to the species level. This technique compares short sequences of the appropriate DNA barcode loci [e.g. mitochondrial cytochrome c oxidase subunit I (COI) gene for insects] of an unidentified specimen with a known DNA barcode library. The accuracy of DNA-based identifications depends on the comprehensiveness of the DNA barcode library. We generated a comprehensive DNA barcode library for a community of rolled-leaf beetles (Coleoptera: Chrysomelidae) in a premontane tropical forest in Costa Rica. The DNA barcode COI accurately identified all beetle species included in the study. Using this DNA barcode library, we identified eggs and larvae of Cephaloleia histrionicaBaly with 100% confidence. This new record of C. histrionica is unique in that this species completes its life cycle on a bromeliad, whereas most Cephaloleia species are associated with plants from the order Zingiberales. The life cycle, diet breadth, immature stages, and sexual dimorphism are described for C. histrionica. copyright 2013 The Linnean Society of London, Biological Journal of the Linnean Society, 2013, 110, 189-198.

However, the diverse chondrichthyan fauna has been poorly documented. Based on recent field discoveries and further analysis of existing collections, the chondrichthyan fauna from this unit comprises at least 26 taxa, of which four species are extinct today. The remaining portion of the total chondrichthyan biodiversity has affinities with modern taxa and is therefore comprised of long-lived species. Based on known records of the modern geographic distribution range of the Gatun chondrichthyans, the fauna has mixed biogeographic affinities suggesting that around 10 million yr ago, a connection likely occurred between the Pacific Ocean and the Caribbean Sea. Given the known habitat preferences for modern chondrichthyans, the Gatun fauna was primarily adapted to shallow waters within the neritic zone. Finally, comparisons of Gatun dental measurements with other faunas suggest that many of the taxa have an abundance of small individuals, in agreement with previous studies that proposed this area as a paleonursery habitat for the species Carcharocles megalodon.

The first group of samples inhabited open and cryptic habitats of shallow (15-20 m) Caribbean reefs at Bocas del Toro Archipelago, Panama. The second group inhabited schiophilous (e.g., inner coral framework and crevices) habitats on shallow reefs (0.5-20 m deep) in Moorea Island, French Polynesia. We applied an integrative approach by combining analyses of external morphology, histological observations, 18S rDNA, and mtCOI to determine the identity and the relationships of these unknown taxa within the order Verongida. Molecular analyses revealed that none of the species studied belonged to Hexadella (Ianthellidae, Verongida), the only fibreless genus of the Order Verongida currently recognized. The species from the Caribbean locality of Bocas del Toro (Panama) belong to the family Ianthellidae and is closely related to the Pacific genera Ianthella and Anomoianthella, both with well-developed fiber reticulations. We suggest the erection of a new generic denomination to include this novel eurypylous, fibreless ianthellid. The species collected in Moorea were all diplodal verongid taxa, with high affinities to a clade containing Pseudoceratina, Verongula, and Aiolochroia, a Pacific and two Caribbean genera, respectively. These unknown species represented at least three different taxa distinguished by DNA sequence analysis and morphological characteristics. Two new genera and a new species of Pseudoceratina are here proposed to accommodate these novel biological discoveries. The evolutionary and ecological meaning of having or lacking a fiber skeleton within Verongida is challenged under the evidence of the existence of fibreless genera within various verongid clades. Furthermore, the discovery of a fibreless Peudoceratina suggests that the possession of a spongin-chitin fiber reticulation is an "ecological" plastic trait that might be lost under certain conditions, such us growing within another organism's skeletal framework. These results raise new questions about the ecological and evolutionary significance of the development of a fiber skeleton and of sponges' adaptability to various environmental conditions.

Despite a basic uniformity of external controls on sedimentation resulting in markedly similar lithologies, facies, facies associations and depositional elements within the rock record across time, there are a number of secular changes, particularly in rates and intensities of processes that resulted in contrasts between preserved Precambrian and Phanerozoic successions. Secular change encompassed (1) variations in mantle heat, rates of plate drift and of continental crustal growth, the gravitational effects of the Moon, and in rates of weathering, erosion, transport, deposition and diagenesis; (2) a decreasing planetary rotation rate over time; (3) no vegetation in the Precambrian, but prolific microbial mats, with the opposite pertaining to the Phanerozoic; (4) the long-term evolution of the hydrosphere-atmosphere-biosphere system. A relatively abrupt and sharp turning point was reached in the Neoarchaean, with spikes in mantle plume flux and tectonothermal activity and possibly concomitant onset of the supercontinent cycle. Substantial and irreversible change occurred subsequently in the Palaeoproterozoic, whereby the dramatic change from reducing to oxidizing volcanic gases ushered in change to an oxic environment, to be followed at ca. 2.4-2.3 Ga by the "Great Oxidation Event" (GOE); rise in atmospheric oxygen was accompanied by expansion of oxygenic photosynthesis in the cyanobacteria. A possible global tectono-thermal "slowdown" from ca. 2.45-2.2 Ga may have separated a preceding plate regime which interacted with a higher energy mantle from a ca. 2.2-2.0Ga Phanerozoic-style plate tectonic regime; the "slowdown" period also encompassed the first known global-scale glaciation and overlapped with the GOE. While large palaeodeserts emerged from ca. 2.0-1.8Ga, possibly associated with the evolution of the supercontinent cycle, widespread euxinia by ca. 1.85Ga ushered in the "boring billion" year period. A second time of significant and irreversible change, in the Neoproterozoic, saw a second major oxidation event and several low palaeolatitude Cryogenian (740-630Ma) glaciations. With the veracity of the "Snowball Earth" model for Neoproterozoic glaciation being under dispute, genesis of Pre-Ediacaran low-palaeolatitude glaciation remains enigmatic. Ediacaran (635-542Ma) glaciation with a wide palaeolatitudinal range contrasts with the circum-polar nature of Phanerozoic glaciation. The observed change from low latitude to circum-polar glaciation parallels advent and diversification of the Metazoa and the Neoproterozoic oxygenation (ca. 580 Ma), and was succeeded by the Ediacaran-Cambrian transition which ushered in biomineralization, with all its implications for the chemical sedimentary record.

Coral reefs are among the most sensitive to this change, as chronic inputs of agricultural and wastewater effluents and atmospheric deposition disrupt their naturally oligotrophic state. Often, anthropogenic alteration of the coastal nitrogen pool can proceed undetected as rapid mixing with ocean waters can mask chronic and ephemeral nitrogen inputs. Monitoring nitrogen stable isotope values ( delta super(15)N) of benthic organisms provides a useful solution to this problem. Through a 7-yr monitoring effort in Quintana Roo, Mexico, we show that delta super(15)N values of the common sea fan Gorgonia ventalina were more variable near a developed (Akumal) site than at an undeveloped (Mahahual) site. Beginning in 2007, the global recession decreased tourist visitations to Akumal, which corresponded with a pronounced 1.6 ppt decline in sea fan delta super(15)N through 2009, at which time delta super(15)N values were similar to those from Mahahual. With the recovery of tourism, delta super(15)N values increased to previous levels. Overall, 84 % of the observed variation in delta super(15)N was explained by tourist visitations in the preceding year alone, indicating that variable nitrogen source contributions are correlated with sea fan delta super(15)N values. We also found that annual precipitation accounted for some variation in delta super(15)N, likely due to its role in groundwater flushing into the sea. Together, these factors accounted for 96 % of the variation in delta super(15)N. Using a mixing model, we estimate that sewage can account for up to 42 % of nitrogen in sea fan biomass. These findings illustrate the high connectivity between land-based activities and coral reef productivity and the measurable impact of the tourism industry on the ecosystem it relies on.

It will measure atmospheric pollution for greater North America from space using ultraviolet and visible spectroscopy. TEMPO measures from Mexico City to the Canadian tar sands, and from the Atlantic to the Pacific, hourly and at high spatial resolution (~2 km N/Sx4.5 km E/W at 36.5[degrees]N, 100[degrees]W). TEMPO provides a tropospheric measurement suite that includes the key elements of tropospheric air pollution chemistry. Measurements are from geostationary (GEO) orbit, to capture the inherent high variability in the diurnal cycle of emissions and chemistry. The small product spatial footprint resolves pollution sources at sub-urban scale. Together, this temporal and spatial resolution improves emission inventories, monitors population exposure, and enables effective emission-control strategies. TEMPO takes advantage of a commercial GEO host spacecraft to provide a modest cost mission that measures the spectra required to retrieve O sub(3), NO sub(2), SO sub(2), H sub(2) CO, C sub(2) H sub(2) O sub(2), H sub(2) O, aerosols, cloud parameters, and UVB radiation. TEMPO thus measures the major elements, directly or by proxy, in the tropospheric O sub(3) chemistry cycle. Multi-spectral observations provide sensitivity to O3 in the lowermost troposphere, substantially reducing uncertainty in air quality predictions. TEMPO quantifies and tracks the evolution of aerosol loading. It provides near-real-time air quality products that will be made widely, publicly available. TEMPO will launch at a prime time to be the North American component of the global geostationary constellation of pollution monitoring together with European Sentinel-4 and Korean GEMS.

To understand the observational properties of CME current sheets, we generated predictions from a flare/CME model to be compared with observations. We use a simulation of a large-scale CME current sheet previously reported by Reeves et al. This simulation includes ohmic and coronal heating, thermal conduction, and radiative cooling in the energy equation. Using the results of this simulation, we perform time-dependent ionization calculations of the flow in a CME current sheet and construct two-dimensional spatial distributions of ionic charge states for multiple chemical elements. We use the filter responses from the Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory and the predicted intensities of emission lines to compute the count rates for each of the AIA bands. The results show differences in the emission line intensities between equilibrium and non-equilibrium ionization. The current sheet plasma is underionized at low heights and overionized at large heights. At low heights in the current sheet, the intensities of the AIA 94 [Angstrom] and 131 [Angstrom] channels are lower for non-equilibrium ionization than for equilibrium ionization. At large heights, these intensities are higher for non-equilibrium ionization than for equilibrium ionization inside the current sheet. The assumption of ionization equilibrium would lead to a significant underestimate of the temperature low in the current sheet and overestimate at larger heights. We also calculate the intensities of ultraviolet lines and predict emission features to be compared with events from the Ultraviolet Coronagraph Spectrometer on the Solar and Heliospheric Observatory, including a low-intensity region around the current sheet corresponding to this model.

AN - 1739084404; 2015-116262 AB - A major revision of the geological timescale was published in 2012. We re-examine our past finding of a 27 Myr periodicity in marine extinction rates by re-assigning dates to the extinction data used previously. We find that the spectral power in this period is somewhat increased, and persists at a narrow bandwidth, which supports our previous contention that the Nemesis hypothesis is untenable as an explanation for the periodicity that was first noted by Raup & Sepkoski in the 1980s. We enumerate a number of problems in a recent study comparing extinction rates with time series models. Copyright (Copyright) 2013. The American Astronomical Society. All rights reserved.

Their formation efficiency and composition are intimately linked to the protoplanetary disk locations of "snow lines" of abundant volatiles. We present chemical imaging of the carbon monoxide (CO) snow line in the disk around TW Hya, an analog of the solar nebula, using high spatial and spectral resolution Atacama Large Millimeter/Submillimeter Array observations of diazenylium (N (sub 2) H (super +) ), a reactive ion present in large abundance only where CO is frozen out. The N (sub 2) H (super +) emission is distributed in a large ring, with an inner radius that matches CO snow line model predictions. The extracted CO snow line radius of approximately 30 astronomical units helps to assess models of the formation dynamics of the solar system, when combined with measurements of the bulk composition of planets and comets.

phylogenetic, evolutionary, and paleoecological significance AN - 1849302566; 2016-105139 AB - Premise of the study: Rhizomorphic lycopsids evolved the tree habit independently of all other land plants. Newly discovered specimens allow radical revision of our understanding of the growth architectures of the extinct Paleozoic sister-genera Synchysidendron and Diaphorodendron. Methods: Detailed descriptions of six remarkable adpression specimens from the Pennsylvanian of the USA and three casts from the late Mississippian of Scotland are used to revise and reanalyze a previously published morphological cladistic matrix and to reinterpret their remarkable growth forms. Key results: Contrary to previous assertions, Synchysidendron resembled Diaphorodendron in having a distinct and relatively complex growth habit that emphasized serially homologous, closely spaced, deciduous lateral branches at the expense of reduced monocarpic crown branches. Lateral branches originated through several strongly anisotomous dichotomies before producing during extended periods large numbers of Achlamydocarpon strobili. The comparatively large diameter of abscission scars remaining on the main trunk and the emergence of branches above the horizontal plane suggest that the lateral branch systems were robust. Lateral branches were borne in two opposite rows on the main trunk and continued upward into an isotomously branched, determinate crown; their striking distichous arrangement caused preferred orientation of fallen trunks on bedding planes. Conclusions: This discovery identifies the plagiotropic growth habit, dominated by serial lateral branches, as ubiquitous in the Diaphorodendraceae and also as unequivocally primitive within Isoetales s.l., a conclusion supported by both the revised morphological cladistic analysis and relative first appearances of taxa in the fossil record. Previously assumed complete homology between crown branching in Lepidodendraceae and that of all earlier-divergent genera requires reassessment. Saltational phenotypic transitions via modification of key developmental switches remains the most credible explanation for architectural evolution in the group. The resulting architecture allowed Diaphorodendraceae to co-dominate disturbed, clastic, equatorial wetlands from the Asbian to the Early Permian.

Although generally treated as separate species, Black-capped chickadees (Poecile atricapillus) and Carolina chickadees (P. carolinensis) hybridize and undergo genetic introgression in many areas where they come into contact across the eastern United States and in the northern Appalachian Mountains. The Great Smoky Mountains harbor the last large breeding population of atricapillus in the southern Appalachians, isolated from the species' main range by nearly 200 km. This population is believed to be reproductively isolated from local carolinensis due to an unusual, behaviorally mediated elevational range gap, which forms during the breeding season and may function as an incipient reproductive isolating mechanism. We examined the effectiveness of this putative isolating mechanism by looking for genetic introgression from carolinensis in Great Smoky Mountain atricapillus. We characterized this population and parental controls genetically using hundreds of amplified fragment length polymorphism (AFLP) loci as well as mitochondrial DNA (mtDNA) sequence data from cytochrome-b. Great Smoky Mountain atricapillus have experienced nuclear genetic introgression from carolinensis, but at much lower levels than other populations near the hybrid zone to the north. No mitochondrial introgression was detected, in contrast to northern contact areas. Thus, the seasonal elevational range gap appears to have been effective in reducing gene flow between these closely related taxa. Black-capped chickadees (Poecile atricapillus) hybridize with Carolina chickadees (P. carolinensis) in the northern Appalachian Mountains. We use genetic data to show that the last large breeding population of atricapillus in the southern Appalachians has experienced genetic introgression from carolinensis, but at a much lower level than populations to the north, confirming that the southern populations are reproductively isolated due to a behaviorally mediated elevational range gap during the breeding season.

A 90 day long time series of full-disk 2 arcsec pixel super(-1) resolution Dopplergrams was acquired in 2001, thanks to the high rate telemetry provided by the Deep Space Network. These Dopplergrams were spatially decomposed using our best estimate of the image scale and the known components of MDI's image distortion. A multi-taper power spectrum estimator was used to generate power spectra for all degrees and all azimuthal orders, up to l = 1000. We used a large number of tapers to reduce the realization noise, since at high degrees the individual modes blend into ridges and thus there is no reason to preserve a high spectral resolution. We used a sophisticated forward modeling to recover the best possible estimate of the underlying mode characteristics (mode frequencies, as well as line widths, amplitudes, and asymmetries).

The interaction among insolation cycles is especially apparent in the paleoenvironmental records of the East African Rift System, where the longest records of human evolution are preserved. However, environmental indicators such as deep-sea oxygen isotopes, terrestrial dust flux, paleosol carbon isotopes, and lake sediments do not point consistently to any simple trend or climate driver of evolutionary change. Comparison of environmental indicators cautions against an exclusive focus on any given end-member of environmental fluctuation (driest or wettest, warmest or coolest), and argues for the impact of the entire range of variability in shaping evolutionary change. A model of alternating high and low climate variability for tropical Africa further implies that specific environmental indicators reflect different aspects of East African environmental dynamics. The model may thus help reconcile some of the conflicting interpretations about the environmental drivers of hominin evolution. First and last appearances of hominin lineages, benchmark biogeographic events, and the emergence of key adaptations and capacities to alter the surroundings are consistently concentrated in the predicted longest intervals of high climate variability. The view that emerges is that important changes in stone technology, sociality, and other aspects of hominin behavior can now be understood as adaptive responses to heightened habitat instability.

The crystals used in the collection of the X-ray data were subsequently analyzed with an electron microprobe and the structural and microprobe results were used to assign site populations. The refined site-scattering values and linear variation in mean bond-length as a function of aggregate-cation radius indicate that Ca is completely ordered at the M(1) site. Similarly Mn is ordered at the M(1) and M(3) sites, with any excess Mn occurring at M(2), and Mg is completely ordered at M(2). Detailed consideration of incident bond-valence sums at the three M sites indicates that the coordination numbers of the M(1), M(2), and M(3) sites are [8], [5], and [6], respectively, although the differences between these and [7], [5], and [5] are very small. Ca is dominant at the M(1) site in a previously refined beusite structure, and there are compositions reported here and elsewhere in which Ca is dominant at M(1) in graftonite-like compositions, indicating the potential for new mineral species in this group.

Palaeontological tests of this model have generally lacked an adequate phylogenetic and modelling framework, whereas tests relying on extant populations lack direct constraints on the evolutionary dynamics within lineages. This study extends a modelling approach developed in comparative studies and applies it to a clade with a rich fossil record, the deep-sea ostracode genus Poseidonamicus. Using a phylogenetic framework and an independent set of shape traits plus body size, a model was fit that allows estimation of anagenetic (within-lineage) evolution, cladogenetic (speciational) change and geographic variation within species. Maximum-likelihood parameter estimates suggested dominantly speciational change for only one or two shape traits, depending on model assumptions. For the remaining shape traits and body size, the contribution of anagenesis was always substantial. Confidence limits on these solutions were quite broad (although narrower when multiple traits were analysed jointly), with most traits consistent with both strongly anagenetic and strongly cladogenetic change. Whereas uncertainty about phylogenetic topology and species limits has little influence on the conclusions, assuming stasis instead of Brownian motion within lineages shifted support to solutions in which speciational change was more dominant, although several traits remained dominantly explained by anagenetic evolution. These results suggest that for the traits and taxa examined, anagenesis contributes substantially to long-term divergence. The uncertainty in the results highlights the analytical difficulty of decomposing anagenetic and cladogenetic sources of phenotypic evolution, even with fossil constraints. When model uncertainty is taken into account, the task of doing so using observations from entirely extant populations is even more daunting.

Most often, these kinds of questions are addressed in the context of variation in evolutionary rates. Shifts in the mode of phenotypic evolution provide an alternative and, in some cases, more realistic explanation for patterns of trait diversity in the fossil record, but these kinds of processes are rarely tested for. In this study, I use a time-calibrated phylogeny of living and fossil Mammaliaformes as a framework to test novel models of body size evolution derived from palaeontological theory. Specifically, I ask whether the K-Pg extinction resulted in a change in rates of body size evolution or release from a constrained adaptive zone. I found that a model comprising an Ornstein-Uhlenbeck process until the K-Pg event and a Brownian motion process from the Cenozoic onwards was the best supported model for these data. Surprisingly, results indicate a lower absolute rate of body size evolution during the Cenozoic than during the Mesozoic. This is explained by release from a stationary OU process that constrained realized disparity. Despite a lower absolute rate, body size disparity has in fact been increasing since the K-Pg event. The use of time-calibrated phylogenies of living and extinct taxa and realistic, process-based models provides unparalleled power in testing evolutionary hypotheses. However, researchers should take care to ensure that the models they use are appropriate to the question being tested and that the parameters estimated are interpreted in the context of the best fitting model.

The outermost zones of the CAIs (< or =1000 mu m from the edge) are not consistently enriched in heavy isotopes relative to the interiors, as might be expected from diffusion-limited surface evaporation of the melt. In all cases, the magnesium in the CAI margins is lighter than in the interiors. In one case, silicon in the margin also is lighter, but locally in some CAIs, it is isotopically heavier near the surface. If melt evaporation played a role in the formation of these outer zones, a later event in many cases caused isotopic re-equilibration with an external and isotopically near-normal reservoir.

The meteorite occurs as clastic grains within postglacial clay-rich layers along the banks of a small stream in the Koryak Mountains, Chukotka Autonomous Okrug of far eastern Russia. Some of the grains are clearly chondritic and contain Type IA porphyritic olivine chondrules enclosed in matrices that have the characteristic platy olivine texture, matrix olivine composition, and mineralogy (olivine, pentlandite, nickel-rich iron-nickel metal, nepheline, and calcic pyroxene [diopside-hedenbergite solid solution]) of oxidized-subgroup CV3 chondrites. A few grains are fine-grained spinel-rich calcium-aluminum-rich inclusions with mineral oxygen isotopic compositions again typical of such objects in CV3 chondrites. The chondritic and CAI grains contain small fragments of metallic copper-aluminum-iron alloys that include the quasicrystalline phase icosahedrite. One grain is an achondritic intergrowth of Cu-Al metal alloys and forsteritic olivine+ or -diopsidic pyroxene, both of which have meteoritic (CV3-like) oxygen isotopic compositions. Finally, some grains consist almost entirely of metallic alloys of aluminum+copper + or - iron. The Cu-Al-Fe metal alloys and the alloy-bearing achondrite clast are interpreted to be an accretionary component of what otherwise is a fairly normal CV3 (oxidized) chondrite. This association of CV3 chondritic grains with metallic copper-aluminum alloys makes Khatyrka a unique meteorite, perhaps best described as a complex CV3 (ox) breccia.

Nonigneous CV CAIs yield well-defined internal (super 26) Al- (super 26) Mg isochrons consistent with the canonical value. These observations indicate that the canonical (super 26) Al/ (super 27) Al ratio records initial Al/Mg fractionation by evaporation and condensation in the CV CAI-forming region. The internal isochrons of igneous CV CAIs show a range of inferred initial (super 26) Al/ (super 27) Al ratios, (4.2-5.2) X 10 (super -5) , indicating that CAI melting continued for at least 0.2 Ma after formation of their precursors. A similar range of initial (super 26) Al/ (super 27) Al ratios is also obtained from the internal isochrons of many CAIs (igneous and nonigneous) in other groups of carbonaceous chondrites. Some CAIs and refractory grains (corundum and hibonite) from unmetamorphosed or weakly metamorphosed chondrites, including CVs, are significantly depleted in (super 26) Al. At least some of these refractory objects may have formed prior to injection of (super 26) Al into the protosolar molecular cloud and its subsequent homogenization in the protoplanetary disk. Bulk aluminum and magnesium-isotope measurements of various types of chondrites plot along the bulk CV CAI isochron, suggesting homogeneous distribution of (super 26) Al and magnesium isotopes in the protoplanetary disk after an epoch of CAI formation. The inferred initial (super 26) Al/ (super 27) Al ratios of chondrules indicate that most chondrules formed 1-3 Ma after CAIs with the canonical (super 26) Al/ (super 27) Al ratio.

Segregating parameters may be of spatial or temporal character and may include behavioral differences. We hypothesized that species of large hunting spider living sympatrically in a Costa Rican lowland rain forest should differ in their habitat and/or hunting microhabitat preferences, in daily activity pattern, and, as an adaptation to the preferred hunting microhabitat, in their specific ability to adhere to smooth surfaces. We found an assemblage of eight large species of the families Ctenidae and Trechaleidae, consisting of three subguilds: 1) two semi-aquatic species with low adhesion ability, 2) three forest-floor dwelling species with good adhesion ability, and 3) three vegetation dwelling species showing very good adhesion ability. The species were partially segregated by habitat type, with two of the vegetation dwelling species preferring the treeless area of a temporary swamp. We found no species-specific differences in daily activity patterns. The similarity in community structure between this Costa Rican and a central Amazonian assemblage suggests the existence of similar structuring mechanisms in wandering spider assemblages in climatically similar biomes.

Our experiment employed artificial stream networks with two simulated tributaries. We used two species of detritivorous caddisflies, Lepidostoma sp. and Pycnopsyche guttifer, in either sympatry (low beta -richness) or allopatry (high beta -richness) in the tributaries of each network. The tributaries were given either senesced or green speckled alder (Alnus incana rugosa). In the networks with senesced leaves, particle export was more than twice as great when the detritivores were in allopatry whereas interference competition in sympatry reduced particle export. In the networks with green leaves, particle export did not significantly vary between the allopatric and sympatric distributions because the interference competition was reduced and the two species had similar feeding rates on green leaves. Humans are altering beta -richness by homogenizing or differentiating flora and fauna across habitats; however, little is known about how altering this type of biodiversity will affect ecosystem functions. Our experimental manipulation is a simple version of a change in the beta -richness of the detritivores in a more complex stream network in nature. These results may indicate that shifts in species distributions across sites may significantly affect ecosystem functions, even when no species are lost from a watershed.

The corollary, that understanding the past might help predict the future, has justified many Late Cretaceous studies, but important questions remain about climate stability and sensitivity. New delta (super 18) O measurements of more than 1000 samples of exceptionally well preserved foraminifera (8 planktic and 11 benthic taxa) from two sites in Tanzania indicate that hot and remarkably stable conditions prevailed in the region during the Turonian, including during a proposed greenhouse glacial event. Planktic taxa have delta (super 18) O values largely between -4.0 per mil and -5.0 per mil, suggesting surface-water temperatures between 30 and 35 degrees C. Estimates for seafloor temperatures are between 18 and 25 degrees C. No parallel shifts in delta (super 18) O values are observed among planktic and benthic taxa, contradicting an often-cited line of evidence for greenhouse glaciations and supporting an effectively ice-free Turonian world.

Here, we report an 8000-year mass balance record from the Nile Delta to reconstruct when and how this sedimentary basin has responded to past hydrological shifts. In a global Holocene context, the long-term decrease in Nile Delta accretion rates is consistent with insolation-driven changes in the 'monsoon pacemaker', attested throughout the mid-latitude tropics. Following the early to mid-Holocene growth of the Nile's deltaic plain, sediment losses and pronounced erosion are first recorded after approximately 4000 years ago, the corollaries of falling sediment supply and an intensification of anthropogenic impacts from the Pharaonic period onwards. Against the backcloth of the Saharan 'depeopling', reduced river flow underpinned by a weakening of monsoonal precipitation appears to have been particularly conducive to the expansion of human activities on the delta by exposing productive floodplain lands for occupation and irrigation agriculture. The reconstruction suggests that the Nile Delta has a particularly long history of vulnerability to extreme events (e.g. floods and storms) and sea-level rise, although the present sediment-starved system does not have a direct Holocene analogue. This study highlights the importance of the world's deltas as sensitive archives to investigate Holocene geosystem responses to climate change, risks and hazards, and societal interaction.

The results demonstrate that the Xiaohe People lived at a well-developed oasis, which was surrounded by extensive desert. The vegetation in the oasis consisted of Populus, Phragmites, Typha and probably of Gramineae, while the desert surrounding the oasis had some common drought-resistant plants dominated by Ephedra, Tamarix, Artemisia and Chenopodiaceae. This present work provides the first data of the environmental background at this site for further archaeological investigation.

681372-2 AB - Through photometric monitoring of the extended transit window of HD 97658b with the MOST space telescope, we have found that this exoplanet transits with an ephemeris consistent with that predicted from radial velocity measurements. The mid-transit times are 5.6sigma earlier than those of the unverified transit-like signals reported in 2011, and we find no connection between the two sets of events. The transit depth together with our determined stellar radius ( (sub IMG .../ (super ) indicates a 2.34 (sub IMG .../ (super R (sub ⊕) super-Earth. When combined with the radial velocity determined mass of 7.86 + or - 0.73 M (sub ⊕) , our radius measure allows us to derive a planet density of 3.44 (sub IMG .../ (super g cm (super -3) . Models suggest that a planet with our measured density has a rocky core that is enveloped in an atmosphere composed of lighter elements. The star of the HD 97658 system is the second brightest known to host a transiting super-Earth, facilitating follow-up studies of this not easily daunted, warm and likely volatile-rich exoplanet.

AN - 1524611027; 2014-031165 AB - The hickory genus (Carya) contains ca. 17 species distributed in subtropical and tropical regions of eastern Asia and subtropical to temperate regions of eastern North America. Previously, the phylogenetic relationships between eastern Asian and eastern North American species of Carya were not fully confirmed even with an extensive sampling, biogeographic and diversification patterns had thus never been investigated in a phylogenetic context. We sampled 17 species of Carya and 15 species representing all other genera of the Juglandaceae as outgroups, with eight nuclear and plastid loci to reconstruct the phylogeny of Carya. The phylogenetic positions of seven extinct genera of the Juglandaceae were inferred using morphological characters and the molecular phylogeny as a backbone constraint. Divergence times within Carya were estimated with relaxed Bayesian dating. Biogeographic analyses were performed in DIVA and LAGRANGE. Diversification rates were inferred by LASER and APE packages. Our results support two major clades within Carya, corresponding to the lineages of eastern Asia and eastern North America. The split between the two disjunct clades is estimated to be 21.58 (95% HPD 11.07-35.51) Ma. Genus-level DIVA and LAGRANGE analyses incorporating both extant and extinct genera of the Juglandaceae suggested that Carya originated in North America, and migrated to Eurasia during the early Tertiary via the North Atlantic land bridge. Fragmentation of the distribution caused by global cooling in the late Tertiary resulted in the current disjunction. The diversification rate of hickories in eastern North America appeared to be higher than that in eastern Asia, which is ascribed to greater ecological opportunities, key morphological innovations, and polyploidy.

Martian meteorites represent the only samples of Mars currently available. Attempts to identify source craters for the meteorites have thus far proven inconclusive (Hamilton et al., 2003; Lang et al., 2009; Mouginis-Mark and Boyce, 2012), precluding their use in constraining the absolute Martian timescale. The majority of the known Martian meteorites are basalts ("shergottites"); all dated shergottites have mineral separate (Rb-Sr or Sm-Nd) ages of <600 Ma (Borg et al., 2005). Here we report a (super 238) U/ (super 206) Pb age of 182.7+ or -6.9 Ma by ion microprobe analysis of baddeleyite (ZrO (sub 2) ) grains in the Zagami shergottite. There is no correlation between discordancy and baddeleyite grain location relative to shock metamorphism. Mineral petrography demonstrates that baddeleyite is the result of late-stage igneous crystallization, and Raman spectroscopy shows that baddeleyite has not been transformed by shock into preservable high-pressure polymorphs. Supported by an age of 153+ or -81 Ma for phosphate grains, obtained using the same method, we conclude that Zagami crystallized at approximately 180 Ma, in agreement with previous results from mineral separate geochronology. Therefore, the shergottites represent igneous rocks preferentially ejected from young terrains on Mars in a small number of ejection events. Abstract Copyright (2013) Elsevier, B.V.

We quantify evolution in the shape of the mass-metallicity relation as a function of redshift; the mass-metallicity relation flattens at late times. There is an empirical upper limit to the gas-phase oxygen abundance in star-forming galaxies that is independent of redshift. From examination of the mass-metallicity relation and its observed scatter, we show that the flattening at late times is a consequence of evolution in the stellar mass where galaxies enrich to this empirical upper metallicity limit; there is also evolution in the fraction of galaxies at a fixed stellar mass that enrich to this limit. The stellar mass where metallicities begin to saturate is approximately 0.7 dex smaller in the local universe than it is at z approximately 0.8. Copyright (Copyright) 2013.

The survey has a 15.6 arcmin angular resolution and achieves a noise level of 15 mJy beam super(-1). We demonstrate a novel interferometric data analysis that involves calibration of drift scan data, integration through the co-addition of warped snapshot images, and deconvolution of the point-spread function through forward modeling. We present a point source catalog down to a flux limit of 4 Jy. We detect polarization from only one of the sources, PMN J0351-2744, at a level of 1.8% + or - 0.4%, whereas the remaining sources have a polarization fraction below 2%. Compared to a reported average value of 7% at 1.4 GHz, the polarization fraction of compact sources significantly decreases at low frequencies. We find a wealth of diffuse polarized emission across a large area of the survey with a maximum peak of ~13 K, primarily with positive rotation measure values smaller than + 10 rad m super(-2). The small values observed indicate that the emission is likely to have a local origin (closer than a few hundred parsecs). There is a large sky area at alpha [> or =, slant] 2 super(h)30 super(m) where the diffuse polarized emission rms is fainter than 1 K. Within this area of low Galactic polarization we characterize the foreground properties in a cold sky patch at ( alpha , delta ) = (4 super(h), -27[degrees].6) in terms of three-dimensional power spectra.

Around massive young stellar objects (MYSOs), icy grain mantles and gas are exposed to increasingly higher temperatures as material accretes from the outer envelope in toward the central hot region. The combination of this temperature profile and the generational chemistry should result in a changing complex molecular composition with radius around MYSOs. We combine IRAM 30 m and Submillimeter Array observations to explore the spatial distribution of organic molecules around the high-mass young stellar object NGC 7538 IRS9, whose weak complex molecule emission previously escaped detection. We find that emission from N-bearing organics and CH (sub 3) OH present substantial increases in emission around 8000 AU and R < 3000 AU, while unsaturated O-bearing molecules and hydrocarbons do not. The increase in line flux for some complex molecules in the envelope, around 8000 AU or 25 K, is consistent with recent model predictions of an onset of complex ice chemistry at 20-30 K. The emission increase for many of the same molecules at R < 3000 AU suggests the presence of a weak hot core, where thermal ice evaporation and hot gas-phase reactions drive the chemistry. Complex organics thus form at all radii and temperatures around this protostar, but the composition changes dramatically as the temperature increases, which is used together with an adapted gas-grain astrochemical model to constrain the chemical generation(s) to which different classes of molecules belong.

Convincing archaeological evidence for pre-Clovis groups is lacking. Paleoindian artifacts including Clovis and Fishtail fluted projectile points have been found at several localities, but at only one site (Vampiros-1) in buried and radiocarbon-dated deposits ( approximately 11,500- approximately 9000 BP). Close similarities between Clovis point reduction sequences at two Panamanian quarry-workshops to those of early US Clovis sites vouch for temporal proximity and suggest rapid movement of Clovis bands through Central America, 11,050-10,800 BP. Vampiros-1 and other rock-shelters were occupied during the early Holocene (10,000-7000 BP) when climate became warmer and wetter. Un-fluted bifacial projectile points were made until approximately 7000 BP. Widespread grinding stones and carbonized tree fruits announce a mixed economy at the beginning of the Holocene. Cultivated leren, arrowroot, squash and bottle gourd appeared by 8000 BP. There are no indicators of human activities at Lake La Yeguada (650 m asl), 14,000-11,150 BP, nor at Vampiros-1, 16,000-11,500 BP. Pre-Clovis populations were probably bound to the now-drowned Pacific coast. Intense burning and deforestation commenced at La Yeguada approximately 11,050 BP coevally with Clovis. Human impacts were thenceforth continuous. Swidden farming had largely removed forest cover by 7000 BP across seasonally arid Central Pacific Panama. Lake sediment data from forested areas with less seasonal climates on the Caribbean and Pacific watersheds indicate moderate human interference before 7000 BP. The mtDNA history of modern Panamanians confirms Native American continuity from before 10,000 BP and provides support for the Pacific route of initial dispersal into South America.

The Paleocene-Eocene Thermal Maximum (PETM), a 200000-yr-long period of rapid carbon release and warming that occurred approximately 56 million years ago, is analogous to future anthropogenic global warming. Methods: We collected plant macrofossils in the Bighorn Basin, Wyoming, United States, from a period spanning the PETM and studied changes in floristic composition. We also compiled and summarized published records of floristic change during the PETM. Key results: There was radical floristic change in the Bighorn Basin during the PETM reflecting local or regional extirpation of mesophytic plants, notably conifers, and colonization of the area by thermophilic and dry-tolerant species, especially Fabaceae. This floristic change largely reversed itself as the PETM ended, though some immigrant species persisted and some Paleocene species never returned. Less detailed records from other parts of the world show regional variation in floristic response, but are mostly consistent with the Bighorn Basin trends. Conclusions: Despite geologically rapid extirpation, colonization, and recolonization, we detected little extinction during the PETM, suggesting the rate of climate change did not exceed the dispersal capacity of terrestrial plants. Extrapolating the response of plants from the PETM to future anthropogenic climate change likely underestimates risk because rates of climate change during the PETM may have been an order of magnitude slower than current rates of change and because the abundant, widespread species common as fossils are likely resistant to extinction.

It happened in retail, banking, government services, and of course libraries. If you've worked in or used libraries for more than twenty years, try to think of all the things patrons once needed personal assistance with but which is now self-service. For example, librarians once mediated the searching of bibliographic databases on behalf of patrons, but since the advent of institutional licensing and IP-based authentication, today's users jump right in and do all their own searching. The digital delivery of information means that librarians have to develop more direct-to-reader services. And because publishing infrastructure and standards are so well developed in science, it will be the science librarians who are first in this area. If we can't deliver content and services to our users in their offices and labs, then it is likely that someone else will. Adapted from the source document.

Taxonomic divisions within the Northern Fulmar have historically been muddled by geographical variation notably including highly polymorphic plumage. Recent molecular analyses (i.e., DNA barcoding) have suggested that genetic divergence between Atlantic and Pacific populations could be on par with those typically observed between species. We employ a multigene phylogenetic analysis to better explore the level of genetic divergence between these populations and to test an old hypothesis on the origin of the modern distribution of color morphs across their range. Additionally, we test whether mutations in the melanocortin-1 receptor gene (MC1R) are associated with dark plumage in the Northern Fulmar. We confirmed that mitochondrial lineages in the Atlantic and Pacific populations are highly divergent, but nuclear markers revealed incomplete lineage sorting. Genetic divergence between these populations is consistent with that observed between many species of Procellariiformes and we recommend elevating these two forms to separate species. We also find that MC1R variation is not associated with color morph but rather is better explained by geographical divergence. We used a multigene phylogenetic approach to investigate population divergence in a Holarctic seabird with an unusual distribution of color morphs. We found land and ice to be a major barrier to dispersal, effectively segregating Atlantic and Pacific populations into independent evolutionary units; however, divergence estimates predate those documented for other Holarctically distributed seabirds. We also examined the link between MC1R variation and color morph but found no correlation. Photos by Mark K. Peck.

II. 12 KEPLER OBJECTS OF INTEREST AND 15 CONFIRMED TRANSITING PLANETS AN - 1654685714; PQ0001039771 AB - All transiting planet observations are at risk of contamination from nearby, unresolved stars. Blends dilute the transit signal, causing the planet to appear smaller than it really is, or producing a false positive detection when the target star is blended with an eclipsing binary. High spatial resolution adaptive optics images are an effective way of resolving most blends. Here we present visual companions and detection limits for 12 Kepler planet candidate host stars, of which 4 have companions within 4". One system (KOI 1537) consists of two similar-magnitude stars separated by 0".1, while KOI 174 has a companion at 0".5. In addition, observations were made of 15 transiting planets that were previously discovered by other surveys. The only companion found within 1" of a known planet is the previously identified companion to WASP-2b. An additional four systems have companions between 1" and 4": HAT-P-30b (3".7, Delta Ks = 2.9), HAT-P-32b (2".9, Delta Ks = 3.4), TrES-1b (2".3, Delta K s = 7.7), and WASP-P-33b (1".9, Delta Ks = 5.5), some of which have not been reported previously. Depending on the spatial resolution of the transit photometry for these systems, these companion stars may require a reassessment of the planetary parameters derived from transit light curves. For all systems observed, we report the limiting magnitudes beyond which additional fainter objects located 0".1-4" from the target may still exist.

It was derived from a section of the Darai Limestone dating to the Burdigalian-Serravallian (early-middle Miocene) and representing shallow platform carbonates. The thoracic vertebrae are remarkably small, being comparable in size to the vertebrae of Nanosiren garciae and implying small body size, although it is uncertain whether the specimen represents a diminutive adult or juvenile individual. These fossils represent the geologically earliest mammal recorded from the island of New Guinea and the earliest evidence of Sirenia in Australasia.

Birds are well represented throughout the stratigraphic sequence at Liang Bua. Here, we present the results of the first comprehensive study of avian remains retrieved from Sector XI, a 2 m by 2 m archaeological excavation along the east wall of the cave. A total of 579 specimens were identified as avian, with 244 belonging to at least 26 non-passerine taxa in 13 families. The late Pleistocene assemblage (23 taxa) includes the first recorded occurrence of vultures in Wallacea, as well as kingfishers, snipes, plovers, parrots, pigeons, and swiftlets. Together, these taxa suggest that during this time the surrounding environment was floristically diverse and included several habitat types. Two of these taxa, the giant marabou Leptoptilos robustus and the vulture Trigonoceps sp., are extinct. Eight taxa were identified in the Holocene assemblage, and five of these were also present in the late Pleistocene. Imperial pigeons Ducula sp. and the Island Collared Dove Streptopelia cf. bitorquata appear only in the Holocene assemblage. The differences in faunal composition between the late Pleistocene and Holocene assemblages may reflect a change in avifaunal composition due to climatic and environmental changes near the Pleistocene-Holocene transition, possibly amplified by impacts associated with the arrival of modern humans; however, the small Holocene sample prevents a firm conclusion about faunal turnover from being made.

Here, we focused on Cecropia sciadophylla individuals inhabiting the extremes of the gradient in seasonality in rainfall at which C. sciadophylla occurs. In Colombia and French Guiana we compared the intra-annual variation in leaf production as well as the intra-annual fluctuation in internode length on a total of 69 saplings ranging in size from 1 to 2 m. The mean rate of leaf production was ~2 leaves mo super(-1) in both populations, and the rate of leaf production was constant throughout the year. Our results showed monthly variation in internode length and the number of live leaves per sapling in the seasonal habitat and variation only in internode length in the everwet habitat. Because the rate of leaf production is constant at both localities, the difference in number of live leaves per sapling at the seasonal site must reflect seasonal variation in leaf life span. We show that in Cecropia, internode length can serve as an indicator of precipitation seasonality. Finally an open question is whether leaf production in other pioneer species is also independent of climatic seasonal cues. This information could allow us to link growth and climate of secondary forest species and better understand how past and future climate can affect plant growth trajectories.

A surprising variety of alteration products occur in association with olivine in MIL 03346, including: patches of incipiently-altered olivine, large Si-enriched olivine-hosted veins (up to 10 mu m across) some of which are complex in morphology and are composed of several phases, small Fe,S(+ or -K)-rich veinlets that crosscut the Si-enriched veins, Ca-sulfates filling cracks in olivine, and secondary Ca-phosphates. Elemental abundances and distributions in these alteration products are consistent with the mobilization of elements from readily dissolved phases in the mesostasis such as phosphates and residual glass. Under favorable weathering conditions, these phases dissolve more readily than pyroxenes, plagioclase, and even olivine at low pH. The occurrence (crosscut and devolatilized by the fusion crust) and composition of Si-enriched alteration veins in olivine are consistent with their formation on Mars. Si-enriched, poorly crystalline alteration products and secondary Ca-sulfates commonly occur in nakhlites, but the habit and composition of these alteration products differ between meteorites. Elemental distributions in these secondary phases suggest at least two episodes of alteration have affected MIL 03346, and subtle differences in secondary minerals and chemistry indicate that each nakhlite experienced its own unique alteration history either on Mars, Earth, or both. The variable Al content and range of morphologies of the olivine-hosted Si-enriched veins suggest variable alteration conditions consistent with a water-limited regime. If the secondary phases in MIL 03346 can be shown to have formed on Mars, their chemistry will provide important clues to the aqueous environments and processes at the time of their formation. However, elevated S and REEs, Ce anomalies, and association of secondary minerals with post-impact cracks and voids indicate that terrestrial weathering has significantly affected MIL 03346. This work highlights the difficulty in distinguishing pre-terrestrial aqueous alteration from later chemical weathering of susceptible mineral phases even in meteorites with limited terrestrial modification.

The large-scale die-off of New England salt marshes was triggered by overfishing and resulted from decades of runaway crab grazing. In 2009, however, cordgrass began to recover, decreasing die-off similar to 40% by 2010. We used surveys and experiments to test whether plant-substrate feedbacks underlie marsh resilience. Initially, grazer-generated die-off swept through the cordgrass, creating exposed, stressful peat banks that inhibited plant growth. This desertification cycle broke when banks eroded and peat transitioned into mud with fewer herbivores, less grazing, and lower physical stress. Cordgrass reestablished in these areas through a feedback where it engineered a recovery zone by further ameliorating physical stresses and facilitating additional revegetation. Our results reveal that feedbacks can play a critical role in rapid, reversible ecosystem shifts associated with human impacts, and that the interplay of facilitative and consumer interactions should be incorporated into resilience theory.

Several areas of barchan and transverse dunes transport sand along definite pathways, feeding the southern part of the Namib Sand Sea from beaches and deflationary basins in the Sperrgebiet. We give a detailed description of the pre- and post-processing routines used for our COSI-Corr analysis, and we evaluate the sub-pixel dune migration results at the dune and dune-field scales. The best set of parameters for the application of the algorithm was systematically derived, resulting in methodological refinements of the cross-correlation windows. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) sensor aboard the Terra satellite provided the remote sensing imagery. Few comparisons have been made between dune migration measurements using COSI-Corr and other types of change detection analysis, and few dune fields have served as test cases for COSI-Corr. We suggest that analysis and interpretation of COSI-Corr output from ASTER data is more valuable if combined with other image analysis techniques, such as manual digitization of dunes in a geographic information system (GIS), processing of write memory function insertion (WMFI) imagery and multispectral image (MSI) analysis of composition. The dune migrations estimated from COSI-Corr results were validated using GIS and WMFI, and later MSI analysis added an important regional, contextual framework of sand transport pathways.

We use a survey of the last three years of articles published in this journal along with a classic data set of Parker from the Gulf of Mexico to show that the familiar practice of citing multiple indices, e.g., Shannon's and Simpson's diversity indices and/or Fisher's alpha , each calculated for the same samples, is redundant and singularly uninformative. In addition, authors often register surprise at the performance of indices when describing diversity over gradients such as depth or time. We show that there is no requirement that the values of the indices be concordant over any gradient and the behavior of a measure can be mathematically determined by the distribution of the observed species. The measures we found to be the most common in current use were S, alpha , H, lambda , and max p (sub i) . The mathematical equivalence of measures is shown through simple plots and description and a standard set of non-redundant measures on a log scale, lnS, H, and ln (1/max p (sub i) ) is recommended. Use of standardized analytical approaches to the study of problems of change in biodiversity removes limitations on the potential for inference concerning local as well as regional and global scales.

However, responses of plant communities to herbivory are variable and depend on environmental conditions, herbivore identity and herbivore abundance. As anthropogenic impacts continue to drive large declines in wild herbivores, understanding the context dependence of herbivore impacts on plant communities becomes increasingly important. Abiotic environmental factors modulate effects of mammalian herbivory on plant communities and are critical to understanding likely impacts of wild herbivore declines. Our results also demonstrate need to be cautious when extrapolating results from exclosure experiments to predict the consequences of defaunation as it proceeds in the Anthropocene, as landscape level results often do not mimic experimental results.

The larval deposition strategy of Allobates femoralis was tested in Southeastern Peru using a blocked, fully crossed experimental design. Arrays of four pools were used to test the effects of pool size and the presence of a predatory insect (Belostomatid) on the deposition behavior of A. femoralis. Further experiments investigated the colonization of insect predators into potential larval habitats and interactions between predatory insects. Results suggest that pool size, the presence of predatory aquatic insects, and interactions between predators, influence larval deposition in A. femoralis. Similar ecological interactions may have driven toxic dendrobatids to the use of arboreal phytotelmata and associated derived reproductive strategies.

Large terrestrial predators can often avoid genetic subdivision due to fragmentation because they have high rates of dispersal-mediated gene flow. Leopards (Panthera pardus) are found in a variety of habitats and are the most widely distributed of the large and middle-sized felids. We investigated the genetic diversity and population substructure of leopards (P.p fusca) in a fragmented meta-population comprised of four populations from five protected areas and inter-connecting corridors spread over an area of 45,000 km2 in central India. Kanha, Pench, Satpura and Melghat Tiger Reserves, and interconnecting corridors in the Satpura-Maikal Landscape of Central India. We collected faecal samples and used genetic methods to identify individuals, estimate the genetic variation and evaluate the patterns of genetic substructuring within this meta-population of leopards. We identified 217 individual leopards using a panel of seven microsatellite loci. Leopards showed high levels of genetic diversity in all sampled populations. Spatial and non-spatial Bayesian analysis revealed at least two admixed genetic populations with indications of ongoing genetic subdivision. Genetic differentiation between populations was not explained by geographic distance. We identified nine individuals as migrants, most of which were assigned to reserves connected by corridors. Our study demonstrates that the leopard, an adaptable and vagile species, can become genetically differentiated with increased habitat fragmentation. Contrary to our hypothesis of panmixia, our results indicate that although leopards in this landscape are admixed, there is genetic substructuring at both the landscape and the fine-scale level. We conclude that this is due to habitat fragmentation and corridors are of immense value in maintaining genetic connectivity in this landscape.

Climate change may alter forest recovery dynamics or even prevent recovery, triggering feedbacks to the climate system, altering regional biodiversity, and affecting the ecosystem services provided by forests. Multiple lines of evidence - including global-scale patterns in forest recovery dynamics; forest responses to experimental manipulation of CO2, temperature, and precipitation; forest responses to the climate change that has already occurred; ecological theory; and ecosystem and earth system models - all indicate that the dynamics of forest recovery are sensitive to climate. However, synthetic understanding of how atmospheric CO2 and climate shape trajectories of forest recovery is lacking. Here, we review these separate lines of evidence, which together demonstrate that the dynamics of forest recovery are being impacted by increasing atmospheric CO2 and changing climate. Rates of forest recovery generally increase with CO2, temperature, and water availability. Drought reduces growth and live biomass in forests of all ages, having a particularly strong effect on seedling recruitment and survival. Responses of individual trees and whole-forest ecosystems to CO2 and climate manipulations often vary by age, implying that forests of different ages will respond differently to climate change. Furthermore, species within a community typically exhibit differential responses to CO2 and climate, and altered community dynamics can have important consequences for ecosystem function. Age- and species-dependent responses provide a mechanism by which climate change may push some forests past critical thresholds such that they fail to recover to their previous state following disturbance. Altered dynamics of forest recovery will result in positive and negative feedbacks to climate change. Future research on this topic and corresponding improvements to earth system models will be a key to understanding the future of forests and their feedbacks to the climate system.

Since the middle 1960s this specific name has been extensively used as a zonal marker of the standard planktonic foraminiferal biochronology, in academic micropalaeontology and economic palaeontology, as well as various disciplines in Cretaceous palaeoenvironmental study. It is threatened by its senior subjective synonym Hedbergella yezoana Takayanagi & Iwamoto, 1962. For nomenclatural stability, the junior name primula should be conserved by suppressing the senior name yezoana.

Through a global survey of mid-ocean ridge basalt glasses, we show that mantle oxidation state varies systematically as a function of mantle source composition. Negative correlations between Fe (super 3+) /Sigma Fe ratios and indices of mantle enrichment-such as (super 87) Sr/ (super 86) Sr, (super 208) Pb/ (super 204) Pb, Ba/La, and Nb/Zr ratios-reveal that enriched mantle is more reduced than depleted mantle. Because carbon may act to simultaneously reduce iron and generate melts that share geochemical traits with our reduced samples, we propose that carbon creates magmas at ridges that are reduced and enriched.

However, it is less clear whether the same holds for late K and M dwarf planet hosts. We report metallicities of Kepler targets and candidate transiting planet hosts with effective temperatures below 4500 K. We use new metallicity calibrations to determine [Fe/H] from visible and near-infrared spectra. We find that the metallicity distribution of late K and M dwarfs monitored by Kepler is consistent with that of the solar neighborhood. Further, we show that hosts of Earth- to Neptune-sized planets have metallicities consistent with those lacking detected planets and rule out a previously claimed 0.2 dex offset between the two distributions at 6sigma confidence. We also demonstrate that the metallicities of late K and M dwarfs hosting multiple detected planets are consistent with those lacking detected planets. Our results indicate that multiple terrestrial and Neptune-sized planets can form around late K and M dwarfs with metallicities as low as 0.25 solar. The presence of Neptune-sized planets orbiting such low-metallicity M dwarfs suggests that accreting planets collect most or all of the solids from the disk and that the potential cores of giant planets can readily form around M dwarfs. The paucity of giant planets around M dwarfs compared to solar-type stars must be due to relatively rapid disk evaporation or a slower rate of planet accretion, rather than insufficient solids to form a core.

The absorption features of O, Fe, Mg, and Si along this line of sight were measured using spectra from the Chandra X-Ray Observatory's LETG/ACIS-S and XMM-Newton's RGS instruments, and the Spex software package. The spectra were fit with dust analogs measured in the laboratory. The O, Mg, and Si abundances were compared to those from standard references, and the O abundance was compared to that along lines of sight toward other X-ray binaries. The results are as follows. First, it was found that a combination of MgSiO (sub 3) (enstatite) and Mg (sub 1.6) Fe (sub 0.4) SiO (sub 4) (olivine) provided the best fit to the O K edge, with N(MgSiO (sub 3) )/N(Mg (sub 1.6) Fe (sub 0.4) SiO (sub 4) ) = 3.4. Second, the Fe L edge could be fit with models that included metallic iron, but it was not well described by the laboratory spectra currently available. Third, the total abundances of O, Mg, and Si were in very good agreement with that of recently re-analyzed B stars, suggesting that they are good indicators of abundances in the local ISM, and the depletions were also in agreement with expected values for the diffuse ISM. Finally, the O abundances found from X-ray binary absorption spectra show a similar correlation with Galactocentric distances as seen in other objects. Copyright (Copyright) 2013.

However, because they are usually rare, surveying threatened species is often expensive and time intensive. Here, we show how regions where common species exhibit high genetic and morphological divergence among populations can be used to predict the occurrence of species of conservation concern. Intraspecific variation of common species of birds, bats and frogs from Ecuador were found to be a significantly better predictor for the occurrence of threatened species than suites of environmental variables or the occurrence of amphibians and birds. Fully 93 per cent of the threatened species analysed had their range adequately represented by the geographical distribution of the morphological and genetic variation found in seven common species. Both higher numbers of threatened species and greater genetic and morphological variation of common species occurred along elevation gradients. Higher levels of intraspecific divergence may be the result of disruptive selection and/or introgression along gradients. We suggest that collecting data on genetic and morphological variation in common species can be a cost effective tool for conservation planning, and that future biodiversity inventories include surveying genetic and morphological data of common species whenever feasible.

However, there are fundamental unsolved problems, such as excessive inward drift of particles in protoplanetary disks during planet formation. Recent theories invoke dust traps to overcome this problem. We report the detection of a dust trap in the disk around the star Oph IRS 48 using observations from the Atacama Large Millimeter/submillimeter Array (ALMA). The 0.44-millimeter-wavelength continuum map shows high-contrast crescent-shaped emission on one side of the star, originating from millimeter-sized grains, whereas both the mid-infrared image (micrometer-sized dust) and the gas traced by the carbon monoxide 6-5 rotational line suggest rings centered on the star. The difference in distribution of big grains versus small grains/gas can be modeled with a vortex-shaped dust trap triggered by a companion.

HiRISE data, with a pixel scale as fine as 25 cm, shows displacements of sand patches, dunes, and ripples up to several meters per Earth year, demonstrating that significant landscape modification occurs in the current environment. This seems to consistently occur in the north polar erg, with variable activity at other latitudes. Volumetric dune and ripple changes indicate sand fluxes up to several cubic meters per meter per year, similar to that found in some dune fields on Earth. All "transverse aeolian ridges" are immobile. There is no relationship between bedform activity and coarse-scale global circulation models, indicating that finer scale topography and wind gusts, combined with the predicted low impact threshold on Mars, are the primary drivers. Several techniques have been developed to measure bedform changes and are largely dependent on dataset availability and the type of questions being pursued. Qualitative visual inspection can determine whether or not changes have occurred. Offsets registered to fixed tie points yield approximate migration rates of nearby crests and dune lee fronts. To compute volumetric sand flux requires precise orthorectification and registration using a digital elevation model base. Using this technique combined with sophisticated change detection software has the potential to detect changes as fine as 1/3 of a pixel ( approximately 8 cm) or less.

These observations provide estimates of two measures of the radial mass distribution of Mercury: the normalized polar moment of inertia and the fractional polar moment of inertia of the solid portion of the planet overlying the liquid core. Employing Monte Carlo techniques, we calculate several million models of the radial density structure of Mercury consistent with its radius and bulk density and constrained by these moment of inertia parameters. We estimate that the top of the liquid core is at a radius of 2020 + or - 30 km, the mean density above this boundary is 3380 + or - 200 kg m (super -3) , and the density below the boundary is 6980 + or - 280 kg m (super -3) . We find that these internal structure parameters are robust across a broad range of compositional models for the core and planet as a whole. Geochemical observations of Mercury's surface by MESSENGER indicate a chemically reducing environment that would favor the partitioning of silicon or both silicon and sulfur into the metallic core during core-mantle differentiation. For a core composed of Fe-S-Si materials, the thermodynamic properties at elevated pressures and temperatures suggest that an FeS-rich layer could form at the top of the core and that a portion of it may be presently solid.

CRaTER measures energetic charged particles that have sufficient energy to penetrate the outer shielding of the instrument (about 12MeV/nucleon). Galactic cosmic rays (GCR) with these energies are the primary radiation concern for spacecraft and astronauts outside of the Earth's magnetosphere during times of minimal solar activity. These particles can easily penetrate typical shielding and damage electronics, causing increased electronics failure rates and single event upsets. When this radiation impacts biological cells, it causes an increased risk of cancer. The CRaTER instrument was built to characterize the radiation dose and lineal energy with unprecedented time and energy resolution and was fortuitously flown during a period of time that coincided with the highest GCR fluxes in the modern space age. We report here this worst-case GCR lineal energy spectrum. Observations are made behind a thin aluminum window and different thicknesses of tissue-equivalent plastic. These measurements provide important observational data points to compare with current model predictions of the dose deposited by energetic particles within a tissue-like material. Key Points * GCR measured by CRaTER during highest flux in space age * Lineal energy spectra are presented from solar minimum * Lineal energy spectra provide basis for detailed transport modeling JF - Space Weather AU - Case, A W AU - Kasper, J C AU - Spence, HE AU - Zeitlin, C J AU - Looper, MD AU - Golightly, MJ AU - Schwadron, NA AU - Townsend, L W AU - Mazur, JE AU - Blake, J B AU - Iwata, Y AD - Smithsonian Astrophysical Observatory, Cambridge, Massachusetts, USA.

Aeolian sand of this erg has been proposed to be derived from the Nile Delta, but empirical data supporting this view are lacking. An alternative source sediment is sand from the large Wadi El Arish drainage system in central and northern Sinai. Mineralogy of the Negev and Sinai dunes shows that they are high in quartz, with much smaller amounts of K-feldspar and plagioclase. Both Nile Delta sands and Sinai wadi sands, upstream of the dunes, also have high amounts of quartz relative to K-feldspar and plagioclase. However, Sinai wadi sands have abundant calcite, whereas Nile Delta sands have little or no calcite. Overall, the mineralogical data suggest that the dunes are derived dominantly from the Nile Delta, with Sinai wadi sands being a minor contributor. Geochemical data that proxy for both the light mineral fraction (SiO (sub 2) /10-Al (sub 2) O (sub 3) + Na (sub 2) O + K (sub 2) O-CaO) and heavy mineral fraction (Fe (sub 2) O (sub 3) -MgO-TiO (sub 2) ) also indicate a dominant Nile Delta source for the dunes. Thus, we report here the first empirical evidence that the Sinai-Negev dunes are derived dominantly from the Nile Delta. Linkage of the Sinai-Negev erg to the Nile Delta as a source is consistent with the distribution of OSL ages of Negev dunes in recent studies. Stratigraphic studies show that during the Last Glacial period, when dune incursions in the Sinai-Negev erg began, what is now the Nile Delta area was characterized by a broad, sandy, minimally vegetated plain, with seasonally dry anastomosing channels. Such conditions were ideal for providing a ready source of sand for aeolian transport under what were probably much stronger glacial-age winds. With the post-glacial rise in sea level, the Nile River began to aggrade. Post-glacial sedimentation has been dominated by fine-grained silts and clays. Thus, sea level, along with favorable climatic conditions, emerges as a major influence on the timing of dune activity in the Sinai-Negev erg, through its control on the supply of sand from the Nile Delta. The mineralogy of the Sinai-Negev dunes is also consistent with a proposed hypothesis that these sediments are an important source of loess in Israel. Abstract Copyright (2013) Elsevier, B.V.

We present single-species stable isotope data for 18 benthic and 11 planktic foraminiferal species and one calcareous dinoflagellate cyst species from a Turonian equatorial record measured on samples collected in SE Tanzania. All microfossils analyzed were excellently preserved and results are compared to isotopic measurements from bulk sediment of the same material. Remarkably low intra-specific variability (standard deviations <0.2 ppm) across the studied interval and consistently large benthic/planktic offsets in delta (super 18) O ( approximately 2.8 ppm) and delta (super 13) C ( approximately 1.5 ppm) indicate absence of major long-term environmental fluctuations and presence of a well stratified water column. Stratigraphic isotopic trends show small shifts that are parallel in all studied benthic species (with the exception of the delta (super 13) C record of Lenticulina species), but within-sample inter-specific offsets reflect a combination of habitat differences and species-specific isotopic disequilibrium fractionation. Among planktic taxa closely related taxa tend to have similar isotopic values. Biserial taxa have the lowest delta (super 18) O values ( approximately -4.7 ppm) but also have relatively low delta (super 13) C values ( approximately 1.6 ppm) indicating that, for the assumption of a surface water habitat, additional metabolic effects need to be involved, which supports the concept of their opportunistic lifestyle. Among trochospiral planktics the keeled taxa with compressed chambers have slightly higher delta (super 18) O ( approximately -4.2 ppm) and lower delta (super 13) C ( approximately 2.3 ppm) values than taxa with globular chambers ( approximately -4.4 ppm and approximately 2.4 ppm, respectively), suggesting differences in habitat or in peak seasonal abundance. Benthic taxa are subdivided into three isotopically distinct groups with differences reflecting mineralogy, life strategy and habitat; Group I: aragonitic taxa (Epistomina, Colomia africana), Group II: calcitic trochospiral taxa with isotopic values seemingly close to equilibrium (Berthelina berthelini, Oridorsalis umbonatus, Lingulogavelinella globosa, Lingulogavelinella convexa) and Group III: calcitic taxa with low delta (super 18) O values and large scatter in delta (super 13) C values (Lenticulina). Four other benthic species show values between Groups II and III. The wealth and consistency of data, especially for benthic taxa, permit refined conclusions. The five studied species of Epistomina have a similar isotopic signature and are inferred to form their aragonitic shells with close to equilibrium values. Small isotopic offsets are seen among species that differ in orientation of the septal foramen, but no offsets are seen that seem to co-vary with test shape or ornamentation. The conical species C. africana has delta (super 18) O values approximately 0.2 ppm lower and delta (super 13) C values approximately 0.7 ppm lower than species of Epistomina. The latter offset probably reflects an infaunal habitat for C. africana. Epistomina and Group II species are recommended for paleoenviromental studies. Mono-specific Lenticulina delta (super 18) O values may be used if increased by correction factors of 0.4 ppm to 0.9 ppm, but this taxon's low and variable delta (super 13) C values are interpreted to reflect incorporation of respiratory CO (sub 2) , possibly combined with fast growth rates related to opportunism, rather than equilibrium with benthic dissolved inorganic carbon. The observed stability of inter-specific isotopic offsets suggests disequilibrium isotopic effects are relatively consistent for many taxa in this section, and correction factors are proposed that may help to generate more robust Upper Cretaceous foraminiferal isotopic records. However, delta (super 18) O/delta (super 13) C covariance in some benthic inter-specific comparisons suggests offsets might vary with changes in temperature, food supply or other factors so the appropriateness of the correction factors should be confirmed before being applied at different sites. Similarities between the observed single-species isotopic patterns from this and other studies are used to present a summarizing scheme of influences on the stable isotopic composition in foraminiferal tests. By applying the new insights from our study to data from other Cretaceous studies we demonstrate that the selection of species for isotopic analysis and understanding these signals are critical to the outcome of paleoceanographic interpretations.

A test in a Caribbean shallow-water lagoon AN - 1429835089; 2013-067958 AB - We compared sponge spicules occurring in surface sediments with those of a living sponge community in a shallow-water reef environment of Bocas del Toro archipelago, Panama, with the goal of evaluating how faithfully spicular analysis reflects the living sponge community. Most megasclere morphotypes present in living species are also found in sediment. On the contrary, microscleres are underrepresented in the sediment samples. Apart from spicules that belong to taxa that live at present in the area, some morphotypes found in the sediment have no equivalent in the known living community. Forty species of living sponges have been recognized in the study area, but 9 (22%) do not produce mineral spicules and, therefore, are not recorded in sediment. Sediment spicules suggest the presence of 22 taxa, thus, loss of information in the process of fossilization is average to considerable, with most living taxa identified also with sediment spicules. Some morphotypes are abundant in sediment (i.e., ovoid spicules) even though the sponges bearing them are rare or absent, thus suggesting either preferential preservation or recent disappearances of taxa producing them. As transport did not play a significant role during the fossilization process, spicular analysis--when all limitations and constraints are considered--is a tenable tool in the reconstruction of former sponge communities, but not of the share of various sponge species. Spicular analysis may also help reveal the presence of cryptic and excavating species that are often overlooked in traditional studies.

He sets in contrast the Star of Ethiopia, an early historical pageant conceived by W.E.B. Du Bois and D.W. Griffith's film The Birth of a Nation, presenting the pair as twinned and warring spectacles which attempted to advance a particular version of American history and the slave past to large portions of the American public.

The tentative diagnosis, following a physical examination under anesthesia, was pneumonia with sepsis. Despite antibiotic treatment and supportive care the chimpanzee died a week following presentation. Gross pathology confirmed severe purulent pneumonia and diffuse hepatosplenic abscesses. Detected in serum at the time of the initial examination, the melioidosis serum antibody titer was elevated (>1:512). Soil samples were collected from three sites in the exhibit at three depths of 5, 15, and 30 cm. By direct and enrichment culture, positive cultures for Burkholderia pseudomallei were found at 5 and 15 cm in one site. The other two sites were positive by enrichment culture at the depth of 5 cm. To prevent disease in the remaining seven troop members, they were relocated to permit a soil treatment with calcium oxide. The exhibit remained empty for approximately 1 yr before the chimpanzees were returned. During that period, the soil in the exhibit area was again cultured as before and all samples were negative for B. pseudomallei. Following the soil treatment in the exhibit, all chimpanzees have remained free of clinical signs consistent with melioidosis.

Three samples show two distinct populations of pyroxene trace element abundances, supporting their classification as dimict. These three meteorites show increases in Y, Yb, and HREE concentrations from harzburgitic to orthopyroxenitic pyroxenes, supporting the hypothesis that the lithologies are related through fractional crystallization whereby harzburgite olivine and pyroxene crystallized from the magma first followed by orthopyroxenite pyroxene. Depletions in LREE and Eu concentrations in the orthopyroxenitic lithology are most likely due to equilibration with LREE and Eu-rich phases, likely plagioclase, which is found primarily in that lithology. Two samples do not show evidence supporting a dimict classification. Large pyroxene trace element variation in one sample indicates that it is polymict, while uniform trace element distribution in the other suggests that it may be a monomict breccia.

These changes have been linked to a reduction in plant biomass as ecosystems age, but the implications for belowground organisms remain unknown. Methods: We constructed a phosphorus budget for the well-studied 120,000 year temperate rainforest chronosequence at Franz Josef, New Zealand. The budget included the amounts of phosphorus in plant biomass, soil microbial biomass, and other soil pools. Results: Soil microbes contained 68-78 % of the total biomass phosphorus (i.e. plant plus microbial) for the majority of the 120,000 year chronosequence. In contrast, plant phosphorus was a relatively small pool that occurred predominantly in wood. This points to the central role of the microbial biomass in determining phosphorus availability as ecosystems mature, yet also indicates the likelihood of strong competition between plants and saprotrophic microbes for soil phosphorus. Conclusions: This novel perspective on terrestrial biogeochemistry challenges our understanding of phosphorus cycling by identifying soil microbes as the major biological phosphorus pool during long-term ecosystem development.

The yearly mean productivity of flat ATS screens was 15.4 g times m super(-2) times d super(-1). This was elevated to 39.6 g times m super(-2) times d super(-1) with a three-dimensional (3-D) screen, and to 47.7 g times m super(-2) times d super(-1) by avoiding high summer harvest temperatures. These methods enhanced nutrient removal (N, P) in algal biomass by 3.5 times. Eighty-six algal taxa (Ochrophyta [diatoms], Chlorophyta [greenalgae], and Cyan-obacteria [blue-green algae]) self-seeded from the GWR and demonstrated yearly cycling. Silica (SiO sub(2)) content of the algal biomass ranged from 30% to 50% of total biomass; phosphorus, nitrogen, and carbon content of the total algal biomass ranged from 0.15% to 0.21%, 2.13% to 2.89%, and 20.0% to 25.7%, respectively. Carbohydrate content (at 10%-25% of AFDM) was dominated by glucose. Lipids (fatty acid methyl ester; FAMEs) ranged widely from 0.5% to 9% AFDM, with Omega-3 fatty acids a consistent component. Mathematical modeling of algal produ-ctivity as a function of temperature, light, and substrate showed a proportionality of 4:3:3, resp-ectively. Under landscape ATS operation, substrate manipulation provides a considerable opportunity to increase ATS productivity, water quality amelioration, and biomass coproduction for fertilizers, fermentation energy, and omega-3 products. Based on the 3-D prod-uctivity and algal chemical composition demonstrated, ATS systems used for nonpoint source water treat-ment can produce ethanol (butanol) at 5.8 per unit area of corn, and biodiesel at 12.0 per unit area of soy beans (agricultural production US).

In contrast, temperate locations such as California's Monterey Bay are fairly well studied. However, even in these locations, studies have tended to focus on a few species or locations. Here we present the results of the first broadscale surveys of invertebrate, fish and algal species richness from a tropical island, Oahu, Hawaii, and a temperate mainland coast, Central California. Data were gathered through surveys of 10 sites in the early 1970s and again in the mid-1990s in San Mateo and Santa Cruz counties, California, and of nine sites in 2001-2005 on Oahu. Surveys were conducted in a similar manner allowing for a comparison between Oahu and Central California and, for California, a comparison between time periods 24 years apart. We report a previously undocumented richness of intertidal species in both locations: 516 for Oahu and 801 for Central California. Surprisingly, when differences in search efforts are controlled, overall (alpha) diversity appears to be similar between locations, although site level (beta) diversity is much higher in California. Species richness in California generally increased along a wave exposure gradient and distance from an urban area. Much higher numbers of both invasive and endemic species were found on Oahu. In California, more invertebrate species were found in the 1990s, likely due to an improvement in taxonomic resources since the 1970s, and species composition was different in the two surveys due to the high incidence of rare species. Although some southern species increased in number between the two time periods and some northern species decreased, we detected little evidence of change favoring southern or northern species. These results are in line with recent findings that water temperatures in the Monterey Bay have been in a cooling trend since the 1980s, in contrast to many locations elsewhere in the world.

Thus, increases in atmospheric pCO sub(2), and consequentially oceanic CO sub(2(aq)) concentrations, may prove beneficial. While addressed in mesocosms, these hypotheses have not been tested in the field with manipulative experimentation. This study examines the effects of in situ CO sub(2(aq)) enrichment on the structural and chemical characteristics of the tropical seagrass, Thalassia testudinum. CO sub(2(aq)) availability was manipulated for 6 months in clear, open-top chambers within a shallow seagrass meadow in the Florida Keys (USA), reproducing forecasts for the year 2100. Structural characteristics (leaf area, leaf growth, shoot mass, and shoot density) were unresponsive to CO sub(2(aq)) enrichment. However, leaf nitrogen and phosphorus content declined on average by 11 and 21 %, respectively. Belowground, non-structural carbohydrates increased by 29 %. These results indicate that increased CO sub(2(aq)) availability may primarily alter the chemical composition of seagrasses, influencing both the nutrient status and resilience of these systems.

With the exception of a handful of objects, the physical nature, and specifically the average densities, of these bodies remain unknown. Here, we propose that the detected giant planet radii may partially belong to planets somewhat less massive than Uranus and Neptune. Accordingly, in this work, we seek to identify a physically sound upper limit to planetary radii at low masses and moderate equilibrium temperatures. As a guiding example, we analyze the interior structure of the Neptune-mass planet Kepler-30d and show that it is acutely deficient in heavy elements, especially compared with its solar system counterparts. Subsequently, we perform numerical simulations of planetary thermal evolution and in agreement with previous studies, show that generally, 10-20 M (sub mass Earth) , multi-billion year old planets, composed of high density cores and extended H/He envelopes can have radii that firmly reside in the giant planet range. We subject our results to stability criteria based on extreme ultraviolet radiation, as well as Roche-lobe overflow driven mass-loss and construct mass-radius relationships for the considered objects. We conclude by discussing observational avenues that may be used to confirm or repudiate the existence of putative low mass, gas-dominated planets. Copyright 2013. The American Astronomical Society.

In this paper, we consider super-Earths with an extensive water mantle (i.e., water planets), and the possibility of entrapment of methane in their extensive water-ice envelopes. We adopt the theory developed by van der Waals & Platteeuw for modeling solid solutions, often used for modeling clathrate hydrates, and modify it in order to estimate the thermodynamic stability field of a new phase called methane filled ice Ih. We find that in comparison to water ice VII the filled ice Ih structure may be stable not only at the high pressures but also at the high temperatures expected at the core-water mantle transition boundary of water planets.

The outermost planets, Kepler-62e and -62f, are super--Earth-size (1.25 R < planet radius < or = 2.0 R) planets in the habitable zone of their host star, respectively receiving 1.2 + or - 0.2 times and 0.41 + or - 0.05 times the solar flux at Earth's orbit. Theoretical models of Kepler-62e and -62f for a stellar age of approximately 7 billion years suggest that both planets could be solid, either with a rocky composition or composed of mostly solid water in their bulk.

Marte Vallis, the largest of the young martian outflow channels (<500 million years old), is embayed by lava flows that hinder detailed studies and comparisons with older channel systems. Understanding Marte Vallis is essential to our assessment of recent Mars hydrologic activity during a period otherwise considered to be cold and dry. Using data from the Shallow Radar sounder on the Mars Reconnaissance Orbiter, we present a three-dimensional (3D) reconstruction of buried channels on Mars and provide estimates of paleohydrologic parameters. Our work shows that Cerberus Fossae provided the waters that carved Marte Vallis, and it extended an additional 180 kilometers to the east before the emplacement of the younger lava flows. We identified two stages of channel incision and determined that channel depths were more than twice those of previous estimates.

Most smooth plains share the spectral characteristics of Mercury's northern smooth plains, suggesting they also share their magnesian alkali-basalt-like composition. A smaller fraction of smooth plains interpreted to be volcanic in nature have a lower reflectance and shallower spectral slope, suggesting more ultramafic compositions, an inference that implies high temperatures and high degrees of partial melting in magma source regions persisted through most of the duration of smooth plains formation. The knobby and hummocky plains surrounding the Caloris basin, known as Odin-type plains, occupy an additional 2% of Mercury's surface. The morphology of these plains and their color and stratigraphic relationships suggest that they formed as Caloris ejecta, although such an origin is in conflict with a straightforward interpretation of crater size-frequency distributions. If some fraction is volcanic, this added area would substantially increase the abundance of relatively young effusive deposits inferred to have more mafic compositions. Smooth plains are widespread on Mercury, but they are more heavily concentrated in the north and in the hemisphere surrounding Caloris. No simple relationship between plains distribution and crustal thickness or radioactive element distribution is observed. A likely volcanic origin for some older terrain on Mercury suggests that the uneven distribution of smooth plains may indicate differences in the emplacement age of large-scale volcanic deposits rather than differences in crustal formational process.

Plants can mediate this microbial competition by releasing oxygen into the rhizosphere and supplying oxidized iron for iron reducers. We utilized a plant removal experiment in two wetland sites to test the hypothesis that, in the absence of plants, rates of iron reduction would be diminished, allowing methanogenesis to dominate anaerobic metabolism. In both sites, methanogenesis was the primary anaerobic mineralization pathway, with iron reduction dominating only early and late in the growing season in the site with a less organic soil. These patterns were not influenced by the presence of plants, demonstrating that plants were not a key control of microbial metabolism. Instead, we suggest that site conditions, including soil chemistry, and temperature are important controls of the pathways of anaerobic metabolism.

Iron reduction is an important carbon mineralization pathway that is capable of suppressing CH (sub 4) production in freshwater wetlands, but our understanding of temperature regulation of iron oxide respiration and the subsequent impacts on CH (sub 4) production is limited. We tested the hypothesis that temperature regulates iron reduction rates indirectly through differential effects on Fe(II) oxidation versus Fe(III) reduction, which ultimately determines the size of the microbially labile, poorly crystalline Fe(III) pool. Our study indicates that rates of iron reduction are more sensitive to changes in temperature than rates of iron oxidation, which creates imbalance in the relative proportion of Fe(II) and Fe(III) in the poorly crystalline soil iron pool as temperatures change. Our results suggest that warmer temperatures can cause the Fe(III) oxide pool to decline, limiting the Fe(III) supply to iron reducers and relieving competition for organic carbon with methanogens.

Long-distance correlations within the formation have been difficult, however, due to the inherent variability of terrestrial systems, the lack of biostratigraphically useful fossils, and the absence of definitive marker horizons in this rock unit. The commonly used lithostratigraphic framework has been shown to have problems as well. Radiometric dating has the potential to help overcome these issues and to aid in correlations across the depositional area. New, geographically diverse U/Pb ages, along with legacy (super 40) Ar/ (super 39) Ar ages (recently recalculated due to the recalibration of the Fish Canyon Tuff sanidine standard to the astronomical timescale), allow significantly improved long-distance correlations. In addition, techniques such as CA-TIMS and the use of an ultra-low lab blank are allowing the University of Wyoming Geochronology Lab to achieve greater precision and accuracy in dating single small ashfall zircons. These crystals often have such a low level of radiogenic lead that they would previously have been deemed un-dateable. The ages being reported here are the result of a combination of these techniques. These new ages, from two geographically disparate fossil localities in the Morrison Formation, can now be used to test previously published correlations of fossil-bearing localities. The ages, from Reed's Quarry 9 at Como Bluff in Albany County, Wyoming and Mygatt-Moore Quarry at Rabbit Valley in Mesa County, Colorado, are both older that expected based on these earlier correlations. These new data support the concept that long-distance correlations of the Morrison Formation based on lithostratigraphy, including a change in the dominant clay mineralogy, should be used with caution in the absence of radiometric dates.

Whether you are a school librarian, a fourth-grader, or the president of the US, new ideas about scope, scale, and speed change everything. So working slowly on the same old tasks, with the same old tools, at the same old speed just is not good enough anymore. It is time for all hands on deck; anyone who can think, teach, or make can play an important role in solving big problems. However, to get the job done people are going to have to change the way they do and think about work, starting now. Three ideas summarize these changes quite powerfully are discussed: Joy's Law, Cognitive Surplus, and 'every user a hero'. Adapted from the source document.

Location The Barro Colorado Nature Monument ( BCNM ), central Panama. The BCNM comprises Barro Colorado Island ( BCI ) and five adjacent mainland peninsulas and is a mosaic of tropical old-growth ( OG ) and secondary forests ( SF ). Methods We studied the species and functional composition of seedling, sapling and adult tree communities in a chronosequence of SF stands ranging in age from 20 to 100 yrs since abandonment, as well as two OG stands for comparison. Functional composition was defined as the representation of species with different degrees of shade tolerance. We also examined patterns of species diversity and dominance to better understand processes driving compositional changes. Results Species diversity recovered rapidly, and, by 20 yrs, species richness for all size classes was equivalent if not higher in SF compared to OG . Species diversity tended to be lower and species dominance higher for seedlings than saplings or adults. Seedling, sapling and adult tree species composition did not clearly increase in similarity to OG with forest age. Instead, differences in species composition among stands reflected variation in dominance by particular species. Light-demanding species became less common and shade-tolerant species more common over stand age, with the functional composition of older secondary forests converging on that of OG . The seedling and sapling communities across the chronosequence were composed of a shade-tolerant subset of those species found in the stands as adults. Conclusion Our results suggest that recruitment into the seedling community of SF is determined by both predictable (e.g. selection for shade-tolerant species) and unpredictable factors (e.g. species-specific reproduction events and dispersal limitation). Recruitment into the sapling and tree communities reflects stronger, and potentially compounded, selection for shade-tolerant species. Therefore, changes in the species composition of regenerating forests in this area appear to be unpredictable, even though the functional composition follows a more deterministic and predictable trajectory with convergence on OG over time. The conservation potential of secondary forests depends on how rapidly and predictably tree communities reassemble in regenerating forests. Our data from secondary forests in central Panama suggest that changes in species composition over succession are unpredictable, but functional composition follows a more deterministic and predictable trajectory with convergence on old-growth over time. The image, which shows Charles Lindbergh flying over Gatun Lake, Panama in 1928, was one of many aerial images used to age forests in this study.

Such data are needed to mitigate the influence of methodological and environmental factors within and between sites and, ultimately, to discriminate between long-term trends and short-term stochastic changes in abundance and community composition. 2.We compared butterfly assemblages using standardised Pollard Walks in the understory of closed-canopy lowland tropical rainforests across three biogeographical regions: Barro Colorado Island (BCI), Panama; Khao Chong (KHC), Thailand; and Wanang (WAN), Papua New Guinea. 3.The length and duration of transects, their spatial autocorrelation, and number of surveys per year represented important methodological factors that strongly influenced estimates of butterfly abundance. Of these, the effect of spatial autocorrelation was most difficult to mitigate across study sites. 4.Butterfly abundance and faunal composition were best explained by air temperature, elevation, rainfall, wind velocity, and human disturbance at BCI and KHC. In the absence of weather data at WAN, duration of transects and number of forest gaps accounted for most of the explained variance, which was rather low in all cases (<33%). 5.Adequate monitoring of the abundance of common butterflies was achieved at the 50ha BCI plot, with three observers walking each of 10 transects of 500m for 30min each, during each of four surveys per year. These data may be standardised further after removing outliers of temperature and rainfall. Practical procedures are suggested to implement global monitoring of rainforest butterflies with Pollard Walks.

AN - 1372059624; 18154900 AB - A fundamental assumption in invasion biology is that most invasive species exhibit enhanced performance in their introduced range relative to their home ranges. This idea has given rise to numerous hypotheses explaining "invasion success" by virtue of altered ecological and evolutionary pressures. There are surprisingly few data, however, testing the underlying assumption that the performance of introduced populations, including organism size, reproductive output, and abundance, is enhanced in their introduced compared to their native range. Here, we combined data from published studies to test this hypothesis for 26 plant and 27 animal species that are considered to be invasive. On average, individuals of these 53 species were indeed larger, more fecund, and more abundant in their introduced ranges. The overall mean, however, belied significant variability among species, as roughly half of the investigated species (N = 27) performed similarly when compared to conspecific populations in their native range. Thus, although some invasive species are performing better in their new ranges, the pattern is not universal, and just as many are performing largely the same across ranges.

Phylogenetic relationships of subgenus Padus were reconstructed using sequences of nuclear ribosomal ITS, and plastid ndhF gene, and rps16 intron and rpl16 intron. Prunus subgenus Padus is shown to be polyphyletic. Taxa of subgenus Padus and subgenus Laurocerasus are highly intermixed in both the ITS and the plastid trees. The results support two disjunctions between eastern North America and Eurasia within the Padus group. One disjunction is between Prunus virginiana of eastern North America and P. padus of Eurasia, estimated to have diverged at 2.99 (95 % HPD 0.59-6.15)-4.1 (95 % HPD 0.63-8.59) mya. The other disjunction is between P. serotina and its Asian relatives. The second disjunction may have occurred earlier than the former one, but the age estimate is difficult due to the unresolved phylogenetic position of the P. serotina complex.

There is good agreement between increasing delta (super 13) C (sub som) and Panicoideae phytolith concentrations, suggesting that variations in C (sub 4) biomass are a major contributor to changes in the soil delta (super 13) C. A measurement error deconvolution curve over time reveals two isotope stages (II-I), with nine sub-stages exhibiting variations in average delta (super 13) C (sub som) (average %C (sub 4) ). Stage II, approximately 10.7-4.3 ka, shows above-average delta (super 13) C (sub som) (increase %C (sub 4) ) values with evidence of an early Holocene warming and dry interval (sub-stage IIb, 9.8-8.3 ka) that coincides with rapid warming and cool-dry abrupt climate-change events. Sub-stage IId, 7.0-4.3 ka, is an above average delta (super 13) C (sub som) (increase %C (sub 4) ) interval associated with the mid-Holocene warm-dry hypsithermal. The Stage II-I shift at 4.3 ka documents a transition toward below average delta (super 13) C (sub som) (decrease %C (sub 4) ) values and coincides with decreasing insolation and hydroclimatic change. Sub-stages Ib and Id (above average %C (sub 4) ) coincide with the first documented occurrence of maize in the northeastern USA and a substantial increase in human population during the Late Woodland. These associations suggest that people influenced delta (super 13) C (sub som) during the late Holocene. Abstract Copyright (2013) Elsevier, B.V.

Here, we report an exceptional mass-mortality assemblage of the basal pelmatozoan Gogia sp., which consists of 106 articulated and nearly complete specimens preserved on a single bedding plane. This slab was collected from the middle Cambrian Spence Shale of Utah, USA, which is characterized by a high-diversity echinoderm fauna that inhabited relatively deepwater distal-ramp settings on a subsiding passive margin of Laurentia. The preferential orientation of specimens strongly suggests that all the animals were entombed by a single unidirectional obrution event; the specimens were most likely derived from a nearby area and represent a single population that was living under the same environmental conditions. Statistical analysis of the thecal heights of specimens, taken as a proxy for age, reveals a bimodal distribution, suggesting that there were at least two episodes of larval settling in the original population. This implies that gogiids displayed seasonal cycles of reproduction, as do many modern echinoderms in equivalent environmental settings. During ontogeny, the theca and stem of Gogia sp. grew by increasing the size of plates, as well as through the incorporation of new plates (e.g., in the sutures between existing ones). The brachioles, by contrast, were more conservative developmentally, and the size of plates was maintained through ontogeny; they grew exclusively through the distal addition of new plates. The epispires, which were used for respiration, are more numerous in adults, as are the brachioles, indicating a degree of metabolic control on the development of these structures. This study demonstrates that taxonomic studies of gogiids should, wherever possible, consider a large number of specimens encompassing a range of sizes in order to clearly distinguish between ontogenetic and interspecific morphological variation.

The resultant palaeoceanographic gap can now be partly bridged by a recent short core of pelagic ooze from Shatsky Rise (Integrated Ocean Drilling Program (IODP) Site U1348), with precise multidisciplinary age constraints developed herein. New oxygen isotope data from very well-preserved benthic foraminifera, together with accurately compiled comparable benthic data from previous Pacific deep-sea sections, exhibit a large (c. +1 per mil) early Campanian shift. We propose the Santonian-Campanian climatic transition was not gradual but was the first major cooling step after sustained mid-Cretaceous hothouse conditions.

Invasive earthworm activity in these same systems, however, may impart a chemical and physical disturbance exceeding that of land use legacy. We established eight plots within forests of the Smithsonian Environmental Research Center (SERC) (Edgewater, MD), to compare sites with no record of significant agricultural disturbance or earthworm activity and successional mixed hardwood forests recovering from past agriculture (60-132 yr) that contained both native and non-native earthworms. Soils (0-15 cm) were separated into physical fractions by size (microaggregates) and density (light and heavy particulate organic matter) and investigated for organic carbon (C) and nitrogen (N) partitioning. In addition, molecular composition was analyzed using FTIR spectroscopy and lignin phenol and substituted fatty acid (SFA) extraction. Even after 132 yr of recovery, the successional forests were nearly devoid of O (sub a+e) horizons; a condition we attribute to high activity of invasive earthworms. Additionally, soil organic carbon (SOC) concentration profiles, and (super 14) C derived mean residence times indicated mixing of the surface soils and fresh input of carbon to 10 cm, distinct from the undisturbed, mature sites. The proportion of microaggregated particulate organic matter (iPOM) and silt+clay (iSC) was significantly higher in successional than undisturbed forests, which we attribute to the combined influence of past agricultural land use and high earthworm activity. Among the successional sites, older forests exhibited a significant decrease in the proportion of C and N in iSC but an increase in their proportion in iPOM, suggesting selective incorporation of iPOM with earthworm activity over great periods of time. In addition, continual consumption and mixing activities of the earthworm population could also be a primary control of the higher concentration and less oxidized lignin phenols as well as a higher proportion of lignin phenols to SFA in all soil fractions in the successional sites. Using partial least squares (PLS) regression of FTIR spectra, we also demonstrated a strong correlation between soil C physical distribution (microaggregated vs. non-microaggregated) and chemical aspects of specific FTIR regions which confirmed our findings from the lignin and SFA and showed distinct chemical dominance among the different sites. Our results indicated that while past agricultural practice may have been the primary initial influence on C and N stock and soil physical distribution in the successional sites, the prolonged legacy and trajectory of recovery from the past land disturbance can be controlled by the nature of the invasive and native earthworm activity during afforestation.

Plants differ in their capacity to use these various forms, which might influence the distribution of species across environmental nutrient gradients.We tested the hypothesis that the distribution of understorey palm species along a soil N gradient in a tropical montane forest in Panama is related to preferences for different chemical forms of N. We conducted a field experiment using 15N-labelled ammonium, nitrate and glycine to examine whether tropical plants show preferences for, or are flexible in, their use of chemical forms of soil N.All species used N from inorganic and organic sources and showed no preference for chemical forms of N. However, across all species, the overall N acquisition pattern was glycine greater than or equal to nitrate greater than or equal to ammonium. Species from low-nutrient sites dominated by ammonium and organic N forms had inherently slow N uptake rates.Synthesis. Patterns in the distribution of understorey palms were related to nitrogen (N) uptake rates rather than preferences for N chemical forms. Down-regulation of N uptake rates may be an important adaptation for plant species associated with low-N soils, with plasticity in N acquisition patterns from various N sources important in alleviating competition for soil N. We found that patterns in the distribution of understorey palms were related to nitrogen (N) uptake rates rather than preferences for N chemical forms.

Treating a hypothesis as if it were evidence or an empirical observation confounds many biogeographical analyses. We focus on two recent publications that address, in part, the evolution of the biota of Sulawesi, the large Indonesian island in the centre of the Indo-Australian Archipelago. Many biogeographical explanations are hampered by invoking simple notions of mechanism or process - dispersal and vicariance - or constraints, such as dispersal from a centre of origin, and, in so doing, dismiss more complex geological phenomena such as emergent volcanoes within island chains or composite areas as irrelevant. Moreover, they do not search for, therefore never discover, biogeographical patterns that may better explain the distribution of biota through time.

Minerals in milk are particularly important for infant skeletal development and may reflect maternal characteristics that are associated with the capacity to synthesize milk and sex-specific developmental priorities of the infant. Using a large sample of mother– ;infant dyads assigned to the outdoor breeding colony at the California National Primate Research Center (N=104), we investigated the relationship of milk calcium (Ca) and phosphorus (P) concentrations and the ratio of Ca/P to maternal and infant characteristics and to other milk variables. Ca and P are largely associated with casein micelles, and as expected, both Ca and P were positively correlated with protein concentrations in milk. Neither Ca nor P concentrations were associated with maternal parity. Mothers rearing daughters tended to produce higher mean Ca concentration in milk, and consequently a higher Ca/P ratio, than did mothers rearing sons, even though protein concentration was not elevated. These results suggest that the Ca/P ratio in rhesus milk may have been under separate selective pressure from protein content to facilitate the accelerated rate of skeletal calcification that has been observed in female Macaca mulatta infants.

At present, however, data on how brain size changes over the course of development are only available from chimpanzees and modern humans. In this study, we examined brain growth in wild Virunga mountain gorillas using data derived from necropsy reports (N = 34) and endocranial volume (EV) measurements (N = 86). The youngest individual in our sample was a 10-day-old neonatal male with a brain mass of 208 g, representing 42% of the adult male average. Our results demonstrate that Virunga mountain gorillas reach maximum adult-like brain mass by 3-4 years of age; adult-sized EV is reached by the time the first permanent molars emerge. This is in contrast to the pattern observed in chimpanzees, which despite their smaller absolute brain size, reportedly attain adult brain mass approximately 1 year later than Virunga mountain gorillas. Our findings demonstrate that brain growth is completed early in Virunga mountain gorillas compared to other great apes studied thus far, in a manner that appears to be linked with other life history characteristics of this population.

Associated faunal evidence, however, is poorly preserved prior to approximately 1.8 Ma, limiting our understanding of early archaeological (Oldowan) hominin carnivory. Here, we detail three large well-preserved zooarchaeological assemblages from Kanjera South, Kenya. The assemblages date to approximately 2.0 Ma, pre-dating all previously published archaeofaunas of appreciable size. At Kanjera, there is clear evidence that Oldowan hominins acquired and processed numerous, relatively complete, small ungulate carcasses. Moreover, they had at least occasional access to the fleshed remains of larger, wildebeest-sized animals. The overall record of hominin activities is consistent through the stratified sequence - spanning hundreds to thousands of years - and provides the earliest archaeological evidence of sustained hominin involvement with fleshed animal remains (i.e., persistent carnivory), a foraging adaptation central to many models of hominin evolution.

It is currently known from the late Middle Triassic (Ladinian) of Germany, the late Middle to early Late Triassic (Ladinian-Carnian) of Argentina and Brazil, and the Late Triassic (Carnian-Norian) of the USA. To date, two unambiguous synapomorphies diagnose Doswelliidae: (i) osteoderm ornamentation coarse, incised, and composed of central regular pits of subequal size and shape, and (ii) osteoderms with anterior articular lamina. Five taxa are currently recognized: Archeopelta arborensis, Doswellia kaltenbachi, Doswellia sixmilensis, Tarjadia ruthae and a new taxon from Germany. Based on skeletal features and occurrence, doswelliid archosauriforms may have had a semi-aquatic mode of life.

Here we uncover several new metallicity trends, which together may indicate that two competing mechanisms deliver close-in giant planets: gentle disk migration, operating in environments with a range of metallicities, and violent planet-planet gravitational interactions, primarily triggered in metal-rich systems in which multiple giant planets can form. First, we show with 99.1% confidence that giant planets with semimajor axes between 0.1 and 1 AU orbiting metal-poor stars ([Fe/H] < 0) are confined to lower eccentricities than those orbiting metal-rich stars. Second, we show with 93.3% confidence that eccentric proto-hot Jupiters undergoing tidal circularization primarily orbit metal-rich stars. Finally, we show that only metal-rich stars host a pile-up of hot Jupiters, helping account for the lack of such a pile-up in the overall Kepler sample. Migration caused by stellar perturbers (e.g., stellar Kozai) is unlikely to account for the trends. These trends further motivate follow-up theoretical work addressing which hot Jupiter migration theories can also produce the observed population of eccentric giant planets between 0.1 and 1 AU.

Milk was collected from 21 Weddell seals Leptonychotes wedddlii in McMurdo Sound, Antarctica, and assayed by standard methods. Milk composition changed over the course of lactation, but at mid- to late lactation (16-40 d postpartum), Weddell seal milk composition was relatively constant at 33.8% + or - 0.82% water, 54.0% + or - 0.80% fat, 10.1% + or -0.16% crude protein, 0.84% + or - 0.03% sugar, 0.75% + or - 0.02% ash, and 23.3 + or - 0.3 kJ g super(-1) whole milk (WM). At this stage, milk composition varied among individual seals in all assayed constituents except ash. The concentration of sugar in the aqueous phase of Weddell seal milk (24.9 + or - 0.6 g sugar L super(-1) water) was ca. 44%-77% of levels found in terrestrial carnivores, indicating that the low sugar concentration of WM is primarily due to its high fat content, not alteration of the aqueous phase. In early lactation, fasting Weddell seals were estimated to devote 39 g d super(-1) glucose to milk sugir synthesis, an amount similar to the estimated demand of the maternal brain. This additional glucose demand must Ik covered by gluconeogenesis in fasting animals and represents a considerable additional drain on maternal resources. However, provision of sugar to offspring at rates sufficient to meet neonatal substrate requirements appears to be essential for efficient fat and protein deposition and thus may be an important component of the phocid reproductive strategy of rapid growth and early weaning.

This goal requires knowledge of the incidence of false positives such as eclipsing binaries in the background of the targets, or physically bound to them, which can mimic the photometric signal of a transiting planet. Using real noise level estimates, we compute the number and characteristics of detectable eclipsing pairs involving main-sequence stars and non-main-sequence stars or planets, and we quantify the fraction of those that would pass the Kepler candidate vetting procedure. By comparing their distribution with that of the Kepler Objects of Interest (KOIs) detected during the first six quarters of operation of the spacecraft, we infer the false positive rate of Kepler and study its dependence on spectral type, candidate planet size, and orbital period. In the process, we also derive a prescription for the signal recovery rate of Kepler that enables a good match to both the KOI size and orbital period distribution, as well as their signal-to-noise distribution.

As with later life-history switch points, plasticity in hatching timing may have carryover effects that affect subsequent interactions with predators and competitors. Moreover, the strength of such effects of hatching plasticity may be context dependent. We used red-eyed treefrogs, Agalychnis callidryas, to test for lasting effects of hatching timing (four or six days post-oviposition) under factorial combinations of resource levels (high or low) and predation risk (none, caged, or lethal Pantala fluvescens dragonfly naiads). Tadpoles were raised in 400-L mesocosms in Gamboa, Panama, from hatching until all animals had metamorphosed or died, allowing assessment of effects across a nearly six-month period of metamorphosis. Hatching early reduced survival to metamorphosis, increased larval growth, and had context-dependent effects on metamorph phenotypes. Early during the period of metamorph emergence, early-hatched animals were larger than late-hatched ones, but this effect attenuated over time. Early-hatched animals also left the water with relatively longer tails. Lethal predators dramatically reduced survival to metamorphosis, with most mortality occurring early in the larval period. Predator effects on the timing of metamorphosis and metamorph size and tail length depended upon resources. For example, lethal predators reduced larval periods, and this effect was stronger with low resources. Predators affected metamorph size early in the period of metamorphosis, whereas resource levels were a stronger determinant of phenotype for animals that metamorphosed later. Effects of hatching timing were detectable on top of strong effects of larval predators and resources, across two subsequent life stages, and some were as strong as or stronger than effects of resources. Plasticity in hatching timing is ecologically important and currently underappreciated. Effects on metamorph numbers and phenotypes may impact subsequent interactions with predators, competitors, and mates, with potentially cascading effects on recruitment and fitness.

Despite being the focus of exhaustive paleoecological sampling studies, previous studies have not revealed the fine-scale spatial and temporal variation in the composition of the Gatun fauna. High-resoluton faunal inventories were conducted from over 600 stratigraphic horizons in the Gatun Formation, capturing more than 200 species, which represent mostly widespread or common, and typically macroscopic taxa. Cluster and detrended correspondence analyses (DCA) reveal a stratigraphic pattern of variation in the faunal composition of individual horizons as well as differences between sampling sites. Stratigraphic curves of DCA axis scores indicate relative shifts in water depth and sedimentation through the stratigraphy and among localities. Overall the Gatun reveals both coarse- and fine-scale temporal variations in paleobathymetry, reflecting long-term shifts in basin subsidence and accommodation space that is potentially overprinted by fifth- or sixth-order glacio-eustatic cycles. The formation accumulated during an overall phase of increasing accommodation space, with major intervals of transgression (lower Gatun), regression (middle Gatun), and further transgression to mid-shelf depths (upper Gatun). Shallowing through the middle part of the Gatun is largely the result of an increase in supply of pyroclastic and volcaniclastic sediments from the adjacent volcanic arc. These findings have implications for understanding the tectonic evolution of the Canal Basin.

A bright fireball was observed throughout a wide area of the midwestern United States. The petrography, mineral compositions, and oxygen isotope ratios indicate that the meteorite is a L5 chondrite fragmental breccia with light/dark structure. The meteorite shows a low shock stage of S2, although some shock-melted veins are present. The U,Th-He age is 0.7 Ga, and the K-Ar age is 1.8 Ga, indicating that Mifflin might have been heated at the time of the 470 Ma L-chondrite parent body breakup and that U, Th-He, and K-Ar ages were partially reset. The cosmogenic radionuclide data indicate that Mifflin was exposed to cosmic rays while its radius was 30-65 cm. Assuming this exposure geometry, a cosmic-ray exposure age of 25 + or - 3 Ma is calculated from cosmogenic noble gas concentrations. The low (super 22) Ne/ (super 21) Ne ratio may, however, indicate a two-stage exposure with a longer first-stage exposure at high shielding. Mifflin is unusual in having a low radiogenic gas content combined with a low shock stage and no evidence of late stage annealing; this inconsistency remains unexplained.

Using the MarsWRF General Circulation Model, we have investigated the seasonality, structure and dynamics of the simulated m = 3 traveling waves and tested the hypothesis that traveling dust storms may enhance m = 3 traveling waves under certain conditions. Our standard simulation using a prescribed "MGS dust scenario" can capture the observed major wave modes and strong near surface temperature variations before and after the northern winter solstice. The same seasonal pattern is also shown by the simulated near surface meridional wind, but not by the normalized surface pressure. The simulated eastward traveling 1.4 < T < 10 sol m = 3 waves are confined near the surface in terms of the temperature perturbation, EP flux and eddy available potential energy, and they extend higher in terms of the eddy winds and eddy kinetic energy. The signature of the simulated m = 3 traveling waves is stronger in the near surface meridional wind than in the near surface temperature field. Compared with the standard simulation, our test simulations show that the prescribed m = 3 traveling dust blobs can enhance the simulated m = 3 traveling waves during the pre- and post-solstice periods when traveling dust storms are frequently observed in images, and that they have negligible effect during the northern winter solstice period when traveling dust storms are absent. The enhancement is even greater in our simulation when dust is concentrated closer to the surface. Our simulations also suggest that dust within the 45-75 degrees N band is most effective at enhancing the simulated m = 3 traveling waves. There are multiple factors influencing the strength of the simulated m = 3 traveling waves. Among those, our study suggests that weaker near surface static stability, larger near surface baroclinic parameter, and wave-form dust forcing for latitudinally extended dust storms are favorable. Further study is needed to fully understand the importance of these factors and others.

We observed that the rate of Cs cation exchange into hexagonal H-birnessite exhibited only a weak dependence on pH, but the total amount of Cs loading in the interlayer region increased dramatically above pH 6.5. The increase in Cs content at higher pH may be attributed to the increasingly negative charge on the Mn-O octahedral sheets and perhaps to a structural change toward triclinic symmetry with high pH. Dissolution at low pH may have inhibited Cs sequestration. Our work supports delamination-reassembly as a mechanism of cation exchange.

Recently, the study of telomere dynamics has been increasingly used to investigate ecological questions. However, little is currently known about the relationships that link environmental conditions, telomere dynamics and fitness in wild vertebrates.Using a small migratory bird (American redstart, Setophaga ruticilla), we investigated how telomere dynamics can be affected by non-breeding habitat quality and to what extent telomere length can predict the return rate of males.We show that telomeres shorten in most individuals over a 1-year period and, importantly, that telomeres of individuals wintering in a low-quality habitat shorten more than those of individuals wintering in a high-quality habitat.In addition, we found that longer telomeres are associated with a higher return rate than shorter telomeres, although the relationship between return rate and telomere length did not depend on habitat quality.Our study suggests that telomere dynamics are affected by environmental conditions and are related to indices of fitness in a migratory bird species.Original Abstract: Lay Summary JF - Functional Ecology AU - Angelier, Frederic AU - Vleck, Carol M AU - Holberton, Rebecca L AU - Marra, Peter P AD - Smithsonian Conservation Biology Institute Migratory Bird Center.

Our study site was in an oil concession within a littoral mosaic landscape. We conducted surveys along 199 line transects and installed camera traps on 99 of these transects to document mammal presence and abundance. We used generalized linear mixed-effect models to document associations between variables related to the ecosystem (land cover, topography, and hydrology), roads (coating, width of rights of way, condition, type of vehicle used on the road, traffic level, affiliation of users, and general type of road), and other human disturbances (urbanization, agriculture, hunting, logging, gathering, and industrial activities) and the abundance or presence of 17 species or groups of mammals including elephant (Loxodonta cyclotis), buffalo (Syncerus caffer), sitatunga (Tragelaphus spekei), red river hog (Potamochoerus porcus), smaller ungulates, gorilla (Gorilla gorilla), chimpanzee (Pan troglodytes), side-striped jackal (Canis adustus), carnivores, monkeys, and large rodents. Some types of roads and other human disturbances were negatively associated with the abundance or presence of elephants, buffalos, gorillas, sitatungas, some monkeys, and duikers. The pattern of associations of mammals with roads and other human disturbances was diverse and included positive associations with road presence (red river hog, some monkeys, and duikers), agriculture (sitatunga, small carnivores, and large rodents) and industrial activities (sitatunga, red river hog, red duikers, and side-striped jackal). Our results suggest that the community of mammals we studied was mostly affected by hunting, agriculture, and urbanization, which are facilitated by road presence. We recommend increased regulation of agriculture, hunting, and road building in the area.Original Abstract: Distribucion de una Comunidad de Mamiferos en Relacion a Carreteras y Otras Perturbaciones Humanas en Gabon, Africa Central Presentamos el primer estudio a nivel de comunidad de la relacion entre carreteras y otras perturbaciones humanas con la distribucion de mamiferos en Gabon (Africa central). Nuestro sitio de estudio esta dentro de una concesion petrolera en un paisaje litoral heterogeneo. Realizamos muestreos a lo largo de 199 transectos lineales e instalamos camaras trampa en 99 de ellos para documentar la presencia y abundancia de mamiferos. Utilizamos modelos lineales generalizados con efectos mixtos para documentar las asociaciones entre variables relacionadas con el ecosistema (cobertura de suelo, topografia e hidrologia), carreteras (tipo de revestimiento, ancho de derecho de via, condicion, tipo de vehiculos que utilizan la carretera, nivel de trafico, afiliacion de los usuarios y el tipo general de carretera) y otras perturbaciones humanas (urbanizacion, agricultura, caza, tala, recolecta y actividades industriales) y la abundancia o presencia de 17 especies o grupos de mamiferos incluyendo elefantes (Loxodonta cyclotis), bufalo (Syncerus caffer), sitatunga (Tragelaphus spekei), cerdo rojo de rio (Potomochoerus porcus), ungulados pequenos, gorila (Gorilla gorilla), chimpance (Pan troglodytes), chacal con rayas a los lados (Canis adustus), carnivoros, monos y roedores de talla grande. Ciertos tipos de carreteras y otras perturbaciones humanas estuvieron asociadas negativamente con la abundancia o presencia de elefantes, bufalos, gorilas, sitatungas, algunos monos y antilopes. Los patrones de asociacion de mamiferos con carreteras y otras perturbaciones humanas fueron diversos e incluyen asociaciones positivas con la presencia de carreteras (cerdo rojo de rio, algunos monos y antilopes), agricultura (sitatunga, carnivoros pequenos y roedores de talla grande) y actividades industriales (sitatunga, cerdo rojo de rio, antilope rojo y chacal con rayas a los lados). Nuestros resultados sugieren que la comunidad de mamiferos que estudiamos fue afectada principalmente por la caza, agricultura y urbanizacion, que son facilitadas por la presencia de carreteras. Recomendamos una mayor regulacion de la agricultura, caza y construccion de carreteras en el area.

Here, we evaluate the hypothesis that the traits that result in performance trade-offs between habitats contribute to the turnover of woody species along a rainfall gradient in the Isthmus of Panama.We studied 24 plant species with contrasting distributions along this rainfall gradient. We measured 18 morphological and physiological traits, and three performance variables in seedlings planted in common garden experiments in two contrasting sites across the Isthmus.We found evidence for a trade-off suggesting that better survival during the dry season corresponded to a lower growth rate in the forest understorey. This trade-off correlated well with the distribution of the species along the rainfall gradient and was explained mostly by variation in photosynthetic capacity.While not all species fit into this trade-off, most dry-distribution species, which we had previously reported to have higher drought survival, were associated with higher stem hydraulic conductance and higher capacity for CO2 assimilation. Our interpretation is that this combination of traits may be associated mostly with desiccation avoidance (deep roots) or desiccation delay (deciduousness) rather than desiccation tolerance. Despite their higher photosynthetic capacity, these species had lower growth in the low-light understorey, probably because of higher maintenance costs (dark respiration rates).Wet-distribution species, on the other hand, had lower photosynthetic capacity and higher leaf area ratio. This strategy is typical of shade-tolerant species and may explain their higher growth rates in the low-light understorey.In conclusion, our results suggest that habitat associations along the rainfall gradient in the Isthmus of Panama may result in part from a trade-off between traits that are favourable to species that avoid or delay desiccation but that otherwise limit shade tolerance. This trade-off may limit the capacity of some dry-distribution species to colonize wet forests.Original Abstract: Lay Summary JF - Functional Ecology AU - Brenes-Arguedas, Tania AU - Roddy, Adam B AU - Kursar, Thomas A AD - Smithsonian Tropical Research Institute.

Many factors affect the accuracy of assessment: e.g. large volume of ballast water, the shape, size and number of ballast tanks and the heterogeneous distribution of organisms within tanks. These factors hinder efforts to obtain samples that truly represent the total ballast water onboard a vessel.A known cell density of Tetraselmis suecica was added to a storage tank and sampled at discharge. The factors holding period, initial cell density and sampling interval affected representativeness. Most samples underestimated cell density, and some tanks with an initial cell density of 100cellsml-1 showed <10cellsml-1 at discharge, i.e. met the D-2 standard. This highlights difficulties in achieving sample representativeness and when applied to a real ballast tank this will be much harder to achieve.

This meeting brought together a diverse group of researchers to discuss recent advances in terrestrial and planetary research on aeolian bedforms. The workshop included two and a half days of oral and poster presentations, as well as one formal (and one informal) full-day field trip. Similar to its predecessors, the presented work provided new insight on the morphology, dynamics, composition, and origin of aeolian bedforms on Venus, Earth, Mars, and Titan, with some intriguing speculation about potential aeolian processes on Triton (a satellite of Neptune) and Pluto. Major advancements since the previous International Planetary Dunes Workshop include the introduction of several new data analysis and numerical tools and utilization of low-cost field instruments (most notably the time-lapse camera). Most presentations represented advancement towards research priorities identified in both of the prior two workshops, although some previously recommended research approaches were not discussed. In addition, this workshop provided a forum for participants to discuss the uncertain future of the Planetary Aeolian Laboratory; subsequent actions taken as a result of the decisions made during the workshop may lead to an expansion of funding opportunities to use the facilities, as well as other improvements. The interactions during this workshop contributed to the success of the Third International Planetary Dunes Workshop, further developing our understanding of aeolian processes on the aeolian worlds of the Solar System.

These heterogeneous materials form a deep layer of dead plant matter that is colonized by a variety of organisms, including fish that forage on the aquatic macro invertebrates found in this unique habitat. In this study, we aimed to characterize which fish species occupy the floating litter banks and their trophic characteristics, as well as determine if fish assemblage composition and species richness can be predicted by the size of the floating litter banks. Fish sampling was conducted in five rivers located in the Amazon basin. Of the 31 floating litter banks sampled that contained fish, 455 individuals were recorded and were distributed within 40 species, 15 families and five orders. Siluriformes were the most representative order among the samples and contained the largest number of families and species. The fish fauna sampled was mainly composed of carnivorous species that are typically found in submerged litter banks of Amazonian streams. The fish assemblage composition in the kinon can be predicted by the volume of the floating litter banks using both presence/absence and abundance data, but not its species richness. In conclusion, kinon banks harbor a rich fish assemblage that utilizes this habitat for shelter and feeding, and may function as a refuge for the fishes during the peak of the flooding season.Original Abstract: Bancos de folhico flutuantes sao habitats efemeros constituidos de troncos e galhos de arvores, flores, sementes e frutos retidos por uma variedade de mecanismos. Estes materiais formam uma camada espessa de materia vegetal morta, que e colonizada por diferentes organismos, incluindo peixes que se alimentam de macroinvertebrados aquaticos presentes neste habitat. Nosso objetivo foi caracterizar as especies e caracteristicas troficas dos peixes que ocupam esses bancos de folhico flutuantes, bem como determinar se a composicao da assembleia de peixes e a riqueza de especies podem ser previstas pelo tamanho dos bancos. A amostragem dos peixes foi realizada em cinco rios da bacia amazonica. Dos 31 bancos de folhico flutuantes amostrados que continham peixes, foram registrados 455 individuos distribuidos em 40 especies, 15 familias e cinco ordens. Siluriformes foi a ordem mais representativa, com o maior numero de especies e familias. A fauna de peixes coletados foi composta principalmente por especies carnivoras, que geralmente sao encontrados em bancos de folhico submersos de igarapes amazonicos. A composicao das assembleias de peixes do 'kinon' pode ser prevista pelo volume desses bancos de liteira flutuante, tanto utilizando dados de presenca/ausencia quanto de abundancia, mas nao de riqueza de especies. Em conclusao, os bancos de folhico flutuante abrigam uma rica assembleia de peixes, que utilizam esse habitat como local de abrigo e de alimentacao, e podem funcionar como refugio para a ictiofauna dos bancos de folhico submerso durante a estacao chuvosa.

ER - TY - JOUR T1 - Vertebrate paleontology of the Cloverly Formation (Lower Cretaceous); I, Faunal composition, biogeographic relationships, and sampling AN - 1469629418; 2013-098089 AB - The vertebrate fauna of the Cloverly Formation has been studied for more than 75 years, but remains poorly sampled and incompletely understood. We undertook an extensive survey of the formation that resulted in the discovery of several new, highly productive vertebrate microfossil bonebeds (VMBs). Comprehensive sampling of these and other sites has nearly doubled the known vertebrate diversity of the Cloverly Formation. In addition to the comparatively well-known dinosaurs, this augmented faunal list includes hybodontoid sharks, numerous bony fishes, three lissamphibian lineages, lizards, multiple crocodylians, and several new mammal occurrences. The known Cloverly vertebrate fauna now more closely resembles those of other late Early Cretaceous formations in North America, indicating broad similarities across wide geographic areas at this time. In addition, this work underscores the important role VMBs can play in areas previously studied primarily through surface prospecting and quarrying, especially for assessing paleoecology and species diversity.

Fossils of A. meridionale are the first record of an anthracothere from the New World Tropics. Among anthracotheres, A. meridionale is most similar to A. acridens from the middle Arikareean from Texas in having a relatively deep and robust jaw, high and sharp cusps on the lower molars, short c-p1 diastema, and absence of a mesiolingual metacristid. A. meridionale differs from other species in being generally larger, two lower incisors (rather than three), prehypocristid never reaching the postprotocristid, more apical junction between postprotocristid and postmetacristid, mesiolingual entocristid transversely notching preentocrisitid, and transverse valley tapered lingually by prehypocristid. Although cladistic analysis of 28 anthracotheriids coded for 51 characters supports a relationship between A. meridionale and A. acridens, some presumably convergent dental characteristics are also similar to certain Oligocene-Miocene Eurasian bothriodontines. The presence of Arretotherium in the Las Cascadas Formation in Panama, and absence in the later Centenario Fauna, shows that primitive bothriodontines entered into Central America by the early Miocene before disappearing from the New World during the late early-middle Miocene.

Our results offer a view of surface properties complementary to Mars Orbiter Laser Altimeter (MOLA) pulse-width or baseline roughness maps and can be compared to SHARAD peak-echo properties to infer deviations from the average near-surface density. Latitudinal averaging of SHARAD-derived roughness over Arabia and Noachis Terrae shows good agreement with MOLA-derived roughness and provides clear evidence for latitude-dependent mantling deposits previously inferred from image data. In northwestern Gordii Dorsum, we find that bulk density in at least the upper few meters is significantly lower than in other units of the Medusae Fossae Formation. We observe the same behavior indicative of low near-surface density in wind-eroded crater fill in the southern highlands. Combining surface-properties analysis, subsurface sounding, and high-resolution optical images, we show that the Pavonis Mons fan-shaped deposit differs significantly from lobate debris aprons which SHARAD has shown to be ice-cored. There are no internal radar reflections from the smooth-facies portion of the Pavonis Mons fan-shaped deposit, and we suggest that these deposits are either quite thin or have little dielectric (i.e., density) contrast with the underlying terrain. Future application of these techniques can identify other low-density units across Mars, assist in the mapping of regional volatile-rich mantling units, and provide new constraints on the physical properties of the polar layered terrain.

Recent excavations of the canal have resulted in new discoveries of many vertebrate fossils, including the first known Miocene crocodylian skulls from Central America. These fossil skulls from the early-middle Miocene represent two new taxa with distinct morphology that is shared with extinct and extant caimans (Caimaninae). A cladistic analysis of 32 alligatorid and three outgroup taxa, scored for 75 characters, resulted in 1210 equally most parsimonious cladograms, all of which suggest that Culebrasuchus mesoamericanus, gen. et sp. nov., is the sister taxon to all previously known Caimaninae. Additionally, the analysis suggests that Centenariosuchus gilmorei, gen. et sp. nov., is the sister taxon to a caimanine clade that includes Purussaurus from the Miocene of South America. In fact, teeth very similar to those of Purussaurus have also been recovered from the Panama Canal. Given these South American affinities, we suggest that these early caimanines dispersed across saltwater. This is a potentially surprising result, because all extant alligatorids lack the salt glands that would have been necessary for the marine dispersal required to reach Central America during the Miocene. Unlike Miocene mammals that all have North American affinities, the Miocene crocodylians of Panama represent a 'melting pot' with taxa of disparate origins living together at the southern extreme of Central America.

This study takes advantage of a time-limited and unique opportunity to recover fossil from renewed excavations of the Panama Canal. The chondrichthyan fauna of the Culebra Formation is composed of teeth and vertebral centra representing 12 taxa. The species found possessed a cosmopolitan tropical and warm-temperate distribution during the early Neogene and are similar to other assemblages of the tropical eastern Pacific and southern Caribbean. The taxa described suggest a neritic environment, and is in contrast with other interpretations that proposed bathyal water depths for the upper member of the Culebra Formation. The wide depth range of the most common species, Carcharocles chubutensis, and the habitat preference of Pristis sp., suggests varied marine environments, from deep, to shallow waters, close to emerged areas of the evolving isthmus.

Underwater screening of the sandy matrix has recovered many dinosaurian teeth. Here we describe and illustrate two types of enigmatic theropod teeth that are referable to Paronychodon and Richardoestesia, respectively. Both of these tooth taxa are well known from the Late Cretaceous of North America and possibly represent stages in the development of the teeth of various paravian theropods. Confirmation of this hypothesis awaits discovery of more complete jaws.

After a peak of discovery and description in the 1910s and 1920s resulting from the Canadian dinosaur rush in the province of Alberta and the Central Asiatic Expeditions to Mongolia of the American Museum of Natural History, the study of ceratopsians declined to a low level until the 1990s, when discoveries in China, Montana, Utah, Alberta, and elsewhere, abetted by increased biostratigraphic and phylogenetic precision, led to an unprecedented resurgence of activity. Even Richard C. Fox, along with colleagues from Peking University, joined in the activity, by naming Psittacosaurus lujiatunensis. To place the activity in historical perspective, half of all known ceratopsians have been described since 2003. Despite important finds of basal ceratopsians in China, Mongolia, and Korea, North America continues to dominate ceratopsian, especially ceratopsid, diversity JF - Canadian Journal of Earth Sciences = Revue Canadienne des Sciences de la Terre AU - Dodson, Peter Y1 - 2013/03// PY - 2013 DA - March 2013 SP - 294 EP - 305 PB - National Research Council of Canada, Ottawa, ON VL - 50 IS - 3 SN - 0008-4077, 0008-4077 KW - North America KW - Diapsida KW - Chordata KW - Cretaceous KW - Fox, Richard C.

Wortmania from the early Paleocene of Montana and an evaluation of the fossil record of the initial diversification of the Taeniodonta (Mammalia) AN - 1429835196; 2013-067626 AB - The Garbani Channel deposits, part of the Tullock Formation exposed in northeastern Montana, have yielded a large sample of vertebrates that probably lived during the Puercan 3 North American Land Mammal Age (NALMA). Four fossils in this sample - three isolated teeth and a medial phalanx - document the presence of a stylinodontid taeniodont, cf. Wortmania. Discovery of cf. Wortmania in the Tullock Formation extends the documented range of taeniodonts during Puercan 3 approximately 500 miles (800 km) northward from the San Juan Basin, New Mexico. Evaluation of the oldest records of taeniodonts, from the Lancian, Puercan, and Torrejonian NALMAs, highlights biases warranting future research. Recent phylogenetic analyses that resulted in numerous ghost lineages indicate that the available fossil record is far from complete. They open the possibility that the origin and initial radiation of taeniodonts occurred in areas yet to be sampled and their first occurrences might reflect immigration of invasive species. The available fossil record of taeniodonts is biased with significantly more abundant and complete specimens discovered in the San Juan Basin than at localities to the north. This bias is also apparent in the available samples of two other lineages of large Puercan mammals, the multituberculate Taeniolabis and the "triisodontid" Eoconodon. Where they occur, taeniodonts are relatively rare members of any local fauna. Is their rarity a product of an ecological bias or a reflection of decreasing population size related to increasing body size?

With 10 species published and several new taxa yet to be named and described, the fossil samples from northern China represent the most species-diverse, individually abundant, and exquisitely preserved salamander fossil assemblage known from the Mesozoic Era. The stratigraphic range of the fossil record covers a geologic time span of roughly 40-45 million years from the Middle Jurassic (Bathonian) through the Early Cretaceous (Aptian). In contrast to the well-known stem-group salamanders Karaurus and Kokartus from the Middle to Late Jurassic of Middle Asia, the Chinese record contains the earliest known crown-group salamanders, including Jurassic representatives of both Cryptobranchoidea and Salamandroidea. The Chinese Mesozoic record includes numerous examples of virtually complete larval, juvenile, young adult, and fully grown adult individuals that collectively provide key information on the life histories and developmental patterns of the earliest known crown-group salamanders. Many specimens show preservation of soft tissue structures, including body outline, eye, liver, and external gill filaments. This kind of soft tissue preservation is unusual for fossil salamanders, so the Chinese Mesozoic specimens are important for furnishing otherwise unavailable information on the life history, diversity, and ecological adaptations of early crown-group salamanders.

The plant fossils are preserved in siltstones and fine-grained sandstones interpreted as overbank sediments that were deposited on an aggrading floodplain. The assemblage is dominated by the cupressaceous conifer Metasequoia foxii and the cercidiphyllaceous dicot Joffrea speirsiae, including their well-preserved seedlings. The flora also contains foliage of the ferns Onoclea and Speirseopteris and the woody dicots Palaeocarpinus, Aphananthe/Celtis, Aesculus, Beringiaphyllum, ?Trochodendron, and Wardiaphyllum, as well as seedlings of unknown dicotyledonous angiosperms. Metasequoia foxii and Speirseopteris are unique to the floras of Gao Mine and the nearby Munce's Hill site (Tiffanian Ti4). The remainder of the taxa are common in late Paleocene floras of North Dakota, Montana, and Wyoming, all USA. The floras of the nearby Joffre Bridge Roadcut and Blindman River sites (both Tiffanian Ti3) are more diverse, but both of those sites encompass a wider range of depositional environments and may include higher percentages of allochthonous material. Most of the Gao Mine material is autochthonous. The seedlings were buried in place, along with the surrounding leaf litter, preserving a record of the local plant community.

Albanerpetontidae, an extinct group of superficially salamander-like amphibians that were widespread across Laurasia during the latter part of the Mesozoic, are represented at Iharkut by 16 fragmentary jaws. Here we describe and figure these specimens as Albanerpetontidae genus and species indeterminate. Based on the age of the Iharkut locality, several premaxillary features, the known distribution (late Early Cretaceous - late Pliocene) of the type genus Albanerpeton, and an unusually large dentary specimen, we suggest that the Iharkut albanerpetontid may pertain to a previously unrecognized species of Albanerpeton, but verification of that must await the recovery of more diagnostically informative specimens, such as frontals and more nearly complete premaxillae. The Iharkut lissamphibian assemblage contains a mixture of taxa with Laurasian (the albanerpetontid and a discoglossid anuran) and Gondwanan (a neobatrachian anuran) affinities. Intriguing higher level differences are evident among Late Cretaceous Laurasian assemblages; for example, urodeles are scarce or absent (as at Iharkut) in Europe, whereas albanerpetontids are scarce in Middle Asia.

Fox, with an annotated list of taxa named between 1962 and 2012 and new photographs for non-mammalian therapsid and mammalian holotypes erected between 1968 and 1994 AN - 1429835059; 2013-067617 AB - Beginning in 1962 and extending to the present, Richard C. Fox and colleagues have named 87 species of fossil vertebrates (1 fish, 4 amphibians, 2 choristoderes, 12 lizards, 1 crocodile, 1 dinosaur, 2 "pelycosaurs", 2 non-mammalian therapsids, and 62 mammals) and numerous new supraspecific taxa. Virtually all of these species continue to be accepted, although the higher-level assignments of several have been altered. The vast majority of the named species were founded on specimens, collected during the mid-1960s to early 2000s by field parties under Fox's direction, from the Late Cretaceous (late Santonian to late Maastrichtian) and Paleocene of Alberta and Saskatchewan, Canada, and that are housed at the University of Alberta Laboratory for Vertebrate Paleontology. Here we present (i) an annotated list of all fossil vertebrate species named by Richard Fox between 1962 and 2012, (ii) updated information on the stratigraphic nomenclature and age estimates for the eight localities in Alberta that yielded holotypes for all the Cretaceous mammal species named by Richard Fox from that province, and (iii) new photographs for the holotypes of the one non-mammalian therapsid and 43 Late Cretaceous and Paleocene mammal species named by Richard Fox before 1995.

We report here the first occurrence of Paleocene mammals from the Porcupine Hills Formation at exposures near the western edge of the city of Calgary. The assemblage, termed the Bearspaw local fauna, documents a diversity of multituberculate and eutherian mammals, including new species of the pentacodontid Aphronorus bearspawensis sp. nov., the mixodectid Eudaemonema bohachae sp. nov., the hyopsodontid Promioclaenus thnetus sp. nov., and a new genus and species of multituberculate (Alopocosmodon hadrus gen. et sp. nov.) tentatively referred to the Microcosmodontidae. The Bearspaw local fauna also details the first Canadian occurrences of several taxa, including Ptilodus wyomingensis, Aphronorus fraudator, Bryanictis microlestes, Elpidophorus minor, and possibly Goniacodon. Preliminary biostratigraphic analyses suggest that the Bearspaw local fauna is middle Torrejonian (To2) in age, correlating most closely with near-coeval Gidley Quarry of Montana and Rock Bench Quarry of Wyoming. In addition to improving the depauperate record of Torrejonian mammals in western Canada, the new fauna is important in documenting a mammal assemblage from a lithological unit that is thought to have been deposited in semi-arid conditions, rather than the wetter and more humid conditions of the Paskapoo Formation. Further, the Bearspaw localities, along with several other recently discovered localities in the Calgary and Cochrane areas, closely bracket the 27n-26r chron boundary and as such will be important in detailing the Torrejonian-Tiffanian transition in western Canada.

New cosmine-covered lower jaws from the Mulga Downs Group, western New South Wales (?Pragian-Emsian or Eifelian), represent the first occurrence of Porolepis in Australia, a genus formerly known exclusively from the Northern Hemisphere. This material is assigned to the new species Porolepis foxi. The wide distribution of Porolepis, demonstrated by its occurrence in New South Wales, Europe, and Spitsbergen, contrasts with the generally high endemicity of the faunas in which it is present.

Four of these, a virtually complete lower molariform cheek tooth, two fragmentary cheek teeth, and a fragmentary lower incisor, are referred to the Sudamericidae (Gondwanatheria). The internal structure of the hypsodont cheek teeth, as revealed by micro-computed tomography scans to simulate different stages of wear, is highly variable. Limited knowledge of intra-individual morphological and size variability in the dentition of sudamericids, which are known almost exclusively from isolated teeth, precludes a conclusive assessment of whether some or all of the new specimens belong to Lavanify miolaka, the only previously described sudamericid from Madagascar, or to a new taxon. Conservatively, therefore, pending the recovery of better material, all four specimens are referred to Sudamericidae gen. et sp. indet. The fifth specimen, a molar fragment, is tentatively allocated to the Multituberculata, thereby adding to the controversial specimens that comprise the very sparse and questionable record of this clade on the southern supercontinent Gondwana. The new specimens do not provide any profound insight into the origins of the highly endemic and imbalanced extant mammalian fauna on Madagascar; rather, they provide only more negative evidence. Like those previously described, they do not represent the basal stocks of any of the five mammalian clades that live on the island today and therefore further support the growing consensus that representatives of the extant clades arrived in the Cenozoic.

At least three non-trionychid turtle taxa can be recognized. Definitely present are a generically indeterminate baenid, the macrobaenid Judithemys backmani, and the chelydrid Protochelydra zangerli. The carapace of a juvenile chelydrid could be either a juvenile of P. zangerli or a fourth, distinct taxon. The macrobaenid J. backmani and the chelydrid P. zangerli are the most abundant non-trionychid turtles from the Paleocene of Alberta. The turtles from the Paleocene of Alberta differ from those of comparable age in New Mexico, USA, and other more southern localities in the North American Western Interior in (i) the presence of macrobaenids and chelydrids and (ii) the absence of kinosternoids. These differences mirror those of the Late Cretaceous, suggesting that biogeographic patterns of non-trionychid turtle distributions that were established during the Late Cretaceous in the Western Interior continued well into the Paleocene.

Multi-variable statistical modeling of siderophile element partitioning between core-forming metallic liquids and silicate melts form the basis for physical models of core formation. While it seems clear that core segregation in a deep peridotitic magma ocean is generally consistent with many mantle siderophile element abundances, there is considerable disparity among extant physical models in terms of the key parameters of pressure, temperature and oxygen fugacity at which the core formed. Moreover, there is ongoing debate over whether simple single-stage equilibrium or more complex multi-stage accretion models are required by the partitioning data. Here we consider how variations in the statistical regression of partitioning data affect the outcomes of physical models for core formation. Taking extant experimental data sets for four well-studied siderophile elements (Ni, Co, W and V) as examples, we find that the regression model exerts a fundamental control on physical model outcomes. Further, the experimental data are currently too imprecise to discriminate among various single-stage and continuous core formation scenarios. Progress in the development of physical models requires better isolation of the independent variables that affect partition coefficients and verification of activity models at high pressure and temperature in order to reduce the global uncertainty in multi-variable statistical models.

We compare the low-diversity, deciduous, temperate Wharton Brook forest (Connecticut, United States) with the high-diversity, evergreen, tropical Noah Creek Rainforest (Queensland, Australia) by mapping one half-hectare of each forest, collecting 25-29 leaf litter samples from four to five depositional settings in each forest and analyzing the relative abundance of species based on >31,750 leaves. In both studies, we analyze the samples as if they were fossil sites, evaluating floral composition, numerical diversity measures, rarefied richness, and climate estimates based on leaf physiognomy. We compare this analysis with data from the standing mapped forest to evaluate the biases inherent in the data derived from fossil assemblages from different depositional settings. In both forests, sample sites that were revisited over multiple years produced different species on subsequent visits, suggesting that fossil sites with close stratigraphic spacing and different composition may actually represent the same source forest. In both forests, species diversity in laterally transported samples appears to increase as the distance of transport increases. Because the species richness of a leaf sample is impacted by the diversity of the original forest, the amount of time the leaf sample spent accumulating, and the effect of transport distance, it is not possible to interpret the diversity of ancient forests without also evaluating the sedimentary facies of the fossil collections.

Most invasions in marine ecosystems are known from bays and estuaries, where ship-mediated transfers (on hulls or in ballasted materials) have been a dominant vector of species introductions. Conspicuous spatial differences in nonnative species richness exist among bays, but the quantitative relationship between invasion magnitude and shipping activity across sites is largely unexplored. Using data on marine invasions (for invertebrates and algae) and commercial shipping across 16 large bays in the United States, we estimated (1) geographic variation in nonnative species richness attributed to ships, controlling for effects of salinity and other vectors, (2) changes through time in geographic variation of these ship-mediated invasions, and (3) effects of commercial ship traffic and ballast water discharge magnitude on nonnative species richness. For all nonnative species together (regardless of vector, salinity, or time period), species richness differed among U.S. coasts, being significantly greater for Pacific Coast bays than Atlantic or Gulf Coast bays. This difference also existed when considering only species attributed to shipping (or ballast water), controlling for time and salinity. Variation in nonnative species richness among Pacific Coast bays was strongly affected by these same criteria. San Francisco Bay, California, had over 200 documented nonnative species, more than twice that reported for other bays, but many species were associated with other (non-shipping) vectors or the extensive low-salinity habitats (unavailable in some bays). When considering only ship- or ballast-mediated introductions in high-salinity waters, the rate of newly detected invasions in San Francisco Bay has converged increasingly through time on that for other Pacific Coast bays, appearing no different since 1982. Considering all 16 bays together, there was no relationship between either (1) number of ship arrivals (from foreign ports) and number of introductions attributed to ships since 1982 or (2) volume of foreign ballast water discharge and number of species attributed to ballast water since 1982. These shipping measures are likely poor proxies for propagule supply, although they are sometimes used as such, highlighting a fundamental gap in data needed to evaluate invasion dynamics and management strategies.

Distinctive elongate structures on neuropteroid pinnules of this plant, previously interpreted as fructifications, are herein reinterpreted as foliar histoid galls, structurally analogous to blister or vein galls, and probably induced by an early lineage of hemipterans or mites. These distinctive features are assigned to the new gall ichnogenus Ovofoligallites Labandeira, n. ichnogen. n. ichnosp, as O. padgetti Labandeira. The Early Permian association between an Odontopteris host and Ovofoligallites gallers probably originated during the Middle Pennsylvanian as a similar, antecedent association between Macroneuropteris scheuchzeri (Hoffmann) Cleal, Shute, and Zodrow and the maker of U-shaped surface features long known as a distinctive, unattributed damage type, but now recognizable as a likely gall. The persistence of this association between the galler and certain medullosan pteridosperms into the Permian adds to the morphological richness of the Permian galler insect fauna. The Permian ecological expansion of galling insects resulted in colonization of new host plants, primarily through a shift from the consumption of entire, mostly pteridophyte axial organs during the Pennsylvanian to the partitioning of seed plant tissues in leaves and small branches in the Permian. The Ovofoligallites galler was part of a diverse Permian galler guild involving a variety of plant taxa, organs and tissues that overwhelmingly targeted multiple lineages of seed plants.

A new genus and species of pipestoneomyid is recognized from the late middle Eocene (Duchesnean North American Land Mammal Age; Bartonian), Argorheomys septendrionalis, which is morphologically more primitive than Pipestoneomys and demonstrates that this new family has been distinct since the Duchesnean. The Pipestoneomyidae share a number of derived characters with the Geomorpha, especially the two-part inner layer of incisor enamel of the Eoymidae. The Pipestoneomyidae differ from the Eomyidae in lacking the basic "omega" pattern of the cheek teeth of the former, so are in the Eomyoidea as a distinct family.

Using an approach that examines radiocarbon dates by region, we argue that the northeastern United States shows a better overall representation of radiocarbon dates when compared to the Mid-Atlantic and Southeast. These data result in a peak in summed probability distributions during the YDC, which is often interpreted as evidence of population growth. Further examination of these distributions, however, illustrates that differential standard deviations, varying sample size, and the effect of taphonomic and research biases likely overwhelm any demographic signatures in our study sample. Consequently, the frequency of radiocarbon dates by itself is insufficient for understanding the relationship between climate, culture and demography in eastern North America.

During a single lunge, rorquals rapidly engulf a large volume of prey-laden water at high speed, which they then filter to capture suspended prey. Engulfment biomechanics are mostly governed by the coordinated opening and closing of the mandibles at large gape angles, which differentially exposes the floor of the oral cavity to oncoming flow. The mouth area in rorquals is delimited by unfused bony mandibles that form kinetic linkages to each other and with the skull. The relative scale and morphology of these skeletal elements have profound consequences for the energetic efficiency of foraging in these gigantic predators. Here, we performed a morphometric study of rorqual mandibles using a data set derived from a survey of museum specimens. Across adult specimens of extant balaenopterids, mandibles range in size from similar to 1-6 m in length, and at their upper limit they represent the single largest osteological element of any vertebrate, living or extinct. Our analyses determined that rorqual mandibles exhibit positive allometry, whereby the relative size of these mandibles becomes greater with increasing body size. These robust scaling relationships allowed us to predict mandible length for fragmentary remains (e.g. incomplete and/or fossil specimens), as we demonstrated for two partial mandibles from the latest Miocene of California, USA, and for mandibles from previously described fossil balaenopterids. Furthermore, we showed the allometry of mandible length to body size in extant mysticetes, which hints at fundamental developmental constraints in mysticetes despite their ecomorphological differences in feeding styles. Lastly, we outlined how our findings can be used to test hypotheses about the antiquity and evolution of lunge feeding.[copy 2012 The Linnean Society of London JF - Biological Journal of the Linnean Society AU - Pyenson, Nicholas D AU - Goldbogen, Jeremy A AU - Shadwick, Robert E AD - Department of Paleobiology National Museum of Natural History.

Grassland specialist birds are an imperilled avifauna for which perennial-based, next-generation agroenergy feedstocks may provide suitable habitat. We take a multi-scaled spatial approach to evaluate the ability of two candidate second-generation agroenergy feedstocks (switchgrass, Panicum virgatum, and mixed grass-forb plantings) to act as spring migratory stopover habitat for birds. In total, we detected 35 bird species in mixed grass-forb plantings and switchgrass plantings, including grassland specialists and species of state and national conservation concern (e.g., Henslow's Sparrow, Ammodramus henslowii). Some evidence indicated that patches with higher arthropod food availability attracted a greater diversity of migrant bird species, but species richness, total bird abundance, and the abundance of grassland specialist species were similar in fields planted with either feedstock. Species richness per unit area (species density) was relatively higher in switchgrass fields. The percent land cover of forest in landscapes surrounding study fields was negatively associated with bird species richness and species density. Habitat patch size and within-patch vegetation structure were unimportant in predicting the diversity or abundance of spring en route bird assemblages. Our results demonstrate that both switchgrass and mixed grass-forb plantings can attract diverse assemblages of migrant birds. As such, industrialized production of these feedstocks as agroenergy crops has the potential to provide a source of en route habitat for birds, particularly where fields are located in relatively unforested landscapes. Because industrialization of cellulosic biomass production will favor as yet unknown harvest and management regimes, predicting the ultimate value of perennial-based biomass plantings for spring migrants remains difficult.

To estimate the phylogenetic relationships among modern horses, zebras, asses and donkeys, we generated the first data set including complete mitochondrial sequences from all seven extant lineages within the genus Equus. Bayesian and Maximum Likelihood phylogenetic inference confirms that zebras are monophyletic within the genus, and the Plains and Grevy's zebras form a well-supported monophyletic group. Using ancient DNA techniques, we further characterize the complete mitochondrial genomes of three extinct equid lineages (the New World stilt-legged horses, NWSLH; the subgenus Sussemionus; and the Quagga, Equus quagga quagga). Comparisons with extant taxa confirm the NWSLH as being part of the caballines, and the Quagga and Plains zebras as being conspecific. However, the evolutionary relationships among the non-caballine lineages, including the now-extinct subgenus Sussemionus, remain unresolved, most likely due to extremely rapid radiation within this group. The closest living outgroups (rhinos and tapirs) were found to be too phylogenetically distant to calibrate reliable molecular clocks. Additional mitochondrial genome sequence data, including radiocarbon dated ancient equids, will be required before revisiting the exact timing of the lineage radiation leading up to modern equids, which for now were found to have possibly shared a common ancestor as far as up to 4 Million years ago (Mya).

Mining, smelting, agriculture, and fossil-fuel combustion are known to have contributed to Pb pollution in lakes of other regions. Few studies, however, have examined Pb sequestered in lakes of the southeastern USA, particulary peninsular Florida, which is subject to less continental atmospheric influence than other regions of the eastern USA. We obtained sediment cores from Little Lake Jackson and Little Lake Bonnet in Highlands County, Florida and used Pb isotopes in the records to identify principal sources of Pb contamination. The sediment records showed that changes in Pb concentration and isotope ratios correspond temporally with gasoline consumption in the USA, as well as with changes in lead ores used to produce leaded gasoline. Lead concentrations in the study lakes showed temporal variations that were similar to those found in peat records from east-central Florida. Isotope trends were similar to the mean USA atmospheric Pb deposition record, and to Pb isotope records from Bermuda and Atlantic corals. We modeled the isotopic composition of the anthropogenic Pb in lake sediments and found that the overall trend is controlled by Pb that was released during leaded gasoline combustion. There is, however, additional Pb at each site that comes from sources that are not fully represented by the natural, background Pb. Lead isotope ratios and Pb/arsenic (As) ratios provide evidence that Pb deposition in lakes during the middle 1900s might have been influenced by lead arsenate applications to golf courses, a source that is often ignored in Pb isotope studies. Isotope evidence confirms, however, that following cessation of commercial lead arsenate use in the 1960s, atmospheric alkyl lead was again the primary influence on Pb in sediments of the study lakes.

Using the domestic cat model, we have demonstrated that the GV can survive simple air-drying and then be hydrated to reconstitute a viable oocyte (Graves-Herring et al., 2013). However, this method can lead to variable DNA damage due to uncontrolled water loss during the dehydration and storage processes. The objective of the present study was to better understand the role of water content during these critical steps on GV DNA integrity. Intraovarian immature oocytes collected from adult cat ovaries were denuded and permeabilized before exposure to 1.5M trehalose for 10min. Oocytes were transferred onto conjugate-release filters and dehydrated with a CEM SAM 255 microwave system. In Experiment 1, samples (n =337 total oocytes, 4-5 replicates) were dehydrated at 20% power for 0, 5, 10, 15, 20, 25, 30 or 40min. Moisture contents were assessed immediately after microwaving using volumetric Karl Fischer titration. Oocytes were rehydrated to assess chromatin configuration (Hoechst staining) and DNA fragmentation (TUNEL assay). Moisture contents progressively decreased (P 0.05) after 40min. Chromatin configuration and proportions of degenerated oocytes (range, 2.2-9.1%) were unaffected (P >0.05) over time. The incidence of GVs with DNA fragmentation was unaltered (P >0.05) from 0 to 30min of treatment (range, 6.1-12%), but increased (P 0.05) thereafter (1 through 4weeks, 25.0-35.0%). This study characterizes, for the first time, the metrics and kinetics of moisture removal, degeneration and DNA damage related to GV desiccation as an alternative approach for preserving the maternal genome at cool or ambient temperature. Findings demonstrate the feasibility for successful microwave dehydration of the mammalian GV to reach an equilibrium moisture content that is non-lethal. Most DNA disruption occurs within the first 2days of storage at supra-zero temperatures and more than two-thirds of GVs retain intact DNA regardless of further moisture loss during storage.

If this occurs, ex situ coral conservation incorporating cryopreservation may provide an important means for successful reef diversification. To build new tools for the continued protection and propagation of coral, an international group of coral and cryopreservation scientists known as the Reef Recovery Initiative joined forces. The outcome was the creation of the first frozen bank for Australian, Caribbean and Hawaiian coral, containing 8 important reef-building species including, Acropora tenuis, Acropora millepora, Acropora loripes, Platygyra daedalea, Platygyra lamolina, Fungia scutaria, Acropora palmata and Acropora cervicornis. Most species of coral are hermaphrodites and reproduce sexually by producing lipid-rich egg/sperm bundles. Generally, self-fertilization is low. A simple, uniform freezing method (10% Me2SO in seawater with a freezing rate of 20 degree C/min) was devised to cryopreserve the sperm of all these species. Coral reproduction is driven by access to sunlight, which powers the intracellular algae to produce complex sugars for the coral. In turn, the coral use these sugars to build lipids needed for the germplasm. Even though we found a unified method for sperm cryopreservation in coral there were physiological challenges. For example, sperm production across the complex web of polyps in single genetic individuals varied. Specifically, in 2011 egg/sperm bundles with more eggs produced more motile sperm. This variation may have been caused by polyp age, prior damage, access to sunlight or a combination of factors. An additional challenge was a 'night-of-preservation' effect whereby some nights the sperm preservation from pooled colonies produced widely differing post-thaw motility, as well as cryopreservation and fertilization success. Finally, when this simple sperm cryopreservation method was used on the Hawaiian acroporid, Montipora captitata, it consistently produced low post-thaw motility and no fertilization success. This species was found to have a toxin in the adult tissue that it transferred to the eggs and possibly the sperm prior to reproduction. Therefore, the release of this toxin from slightly damaged sperm cells may have impacted these post-thaw results, and may ultimately inhibit the successful cryopreservation of this species. Finally, coral larvae have not been successfully cryopreserved because of their exquisite chilling sensitivity. Nevertheless, pluripotent 8-cell embryos were successfully dissociated, frozen and thawed with 50 to 90% intact cells post-thaw in all species tested. Frozen and thawed coral sperm can now be used to create new coral, as they develop, settle and take up their intracellular algae. In the near future, we may have a blueprint to move our work from the laboratory to the reefs to develop collaborative, practical conservation management tools to secure reef biodiversity.

Hypotheses to explain sexual dimorphism in avian bill size include divergence in feeding niche or thermoregulatory demands, intrasexual selection based on increased competition among males, or female preference. Birds also show seasonal changes in bill size due to shifts in the balance between growth rate and wear, which may be due to diet or endogenous rhythms in growth. Insight into the function of dimorphism can be gained using the novel approach of digital x-ray imaging of museum skins to examine the degree to which the skeletal core or the rhamphotheca contribute to overall dimorphism. The rhamphotheca is ever-growing and ever-wearing, varying in size throughout life; whereas the skeletal core shows determinant growth. Because tidal marsh sparrows are more dimorphic in bill size than related taxa, we selected two marsh taxa to investigate dimorphism and seasonality in the size of the overall bill, the skeletal core, and the rhamphotheca. Bill size varied by sex and season, with males having larger bills than females, and bill size increasing from nonbreeding to breeding season more in males. Skeletal bill size varied with season, but not sex. The rhamphotheca varied primarily with sex; males had a larger rhamphotheca (corrected for skeletal bill size), which showed a greater seasonal increase than females. The rhamphotheca, rather than the skeletal bill, was responsible for sexual dimorphism in overall bill size, which was particularly well developed in the breeding season. The size of the rhamphotheca may be a condition-based character that is shaped by sexual selection. These results are consistent with the evidence that bill size is influenced by sexual selection as well as trophic ecology. We demonstrate that sexual dimorphism in the bill of two sparrows is restricted to the horny covering (rhamphotheca). Both bill and rhamphotheca are largest in the breeding season and the seasonal increase is found primarily in males. These results highlight the under appreciated role of a dynamic rhamphotheca driving patterns of bill morphology and provide a mechanism for the bill, a structure thought to be shaped by trophic ecology, to be the focus of condition-based sexual selection.

We present Spitzer 10-35 mu m spectroscopic data centered at both stars and identify warm, unresolved excess emission in the close vicinity of Vega for the first time. The properties of the warm excess in Vega are further characterized with ancillary photometry in the mid-infrared and resolved images in the far-infrared and submillimeter wavelengths. The Vega warm excess shares many similar properties with the one found around Fomalhaut. The emission shortward of approximately 30 mu m from both warm components is well described as a blackbody emission of approximately 170 K. Interestingly, two other systems, epsilon Eri and HR 8799, also show such an unresolved warm dust using the same approach. These warm components may be analogous to the solar system's zodiacal dust cloud, but of far greater mass (fractional luminosity of approximately 10 (super -5) to 10 (super -6) compared to 10 (super -8) to 10 (super -7) ). The dust temperature and tentative detections in the submillimeter suggest that the warm excess arises from dust associated with a planetesimal ring located near the water-frost line and presumably created by processes occurring at similar locations in other debris systems as well. We also review the properties of the 2 mu m hot excess around Vega and Fomalhaut, showing that the dust responsible for the hot excess is not spatially associated with the dust we detected in the warm belt. We suggest it may arise from hot nano grains trapped in the magnetic field of the star. Finally, the separation between the warm and cold belt is rather large with an orbital ratio > or =10 in all four systems. In light of the current upper limits on the masses of planetary objects and the large gap, we discuss the possible implications for their underlying planetary architecture and suggest that multiple, low-mass planets likely reside between the two belts in Vega and Fomalhaut.

Spectral mapping by the Dawn spacecraft reveals orthopyroxene-rich materials, similar to diogenite meteorites, in the deepest parts of the basin and within its walls. Significant amounts of olivine are predicted for the mantles of bulk-chondritic bodies like Vesta, and its occurrence is demonstrated by some diogenites that are harzburgite and dunite. However, olivine has so far escaped detection by Dawn's instruments. Spectral detection of olivine in the presence of orthopyroxene is difficult in samples with <25% olivine, and olivine in Rheasilvia might have been diluted during impact mixing or covered by the collapse of basin walls. The distribution of diogenite inferred from its exposures in and around Rheasilvia provides a geologic context for the formation of these meteorites, but does not clearly distinguish between a magmatic cumulate versus partial melting restite origin for diogenites. The former is favored by geochemical arguments, and crystallization in either a magma ocean or multiple plutons emplaced near the crust-mantle boundary is permitted by Dawn observations.

Fluvial erosion around the Noachian/Hesperian transition is better constrained than the longer-term landscape evolution throughout the Noachian Period, when the highland intercrater geomorphic surfaces developed. We interpret highland resurfacing events and processes using a new global geologic map of Mars (at 1:20,000,000 scale), a crater data set that is complete down to 1 km in diameter, and Mars Orbiter Laser Altimeter topography. The Early Noachian highland (eNh) unit is nearly saturated with craters of 32-128 km diameter, the Middle Noachian highland (mNh) unit has a resurfacing age of approximately 4 Ga, and the Late Noachian highland unit (lNh) includes younger composite surfaces of basin fill and partially buried cratered terrain. These units have statistically distinct ages, and their distribution varies with elevation. The eNh unit is concentrated in the high-standing Hellas basin annulus and in highland terrain that was thinly mantled by basin ejecta near 180 degrees longitude. The mNh unit includes most of Arabia Terra, the Argyre vicinity, highland plateau areas between eNh outcrops, and the Thaumasia range. The lNh unit mostly occurs within highland basins. Crater depth/diameter ratios do not vary strongly between the eNh and mNh units, although crater losses to Noachian resurfacing appear greater in lower lying areas. Noachian resurfacing was spatially non-uniform, long-lived, and gravity-driven, more consistent with arid-zone fluvial and aeolian erosion and volcanism than with air fall mantling or mass wasting.

The Lunar Reconnaissance Orbiter Camera now provides meter-scale images of more than 100 lobate scarps, as well as stereo-derived topography of about a dozen scarps. High-resolution digital terrain models (DTMs) provide unprecedented insight into scarp morphology and dimensions. Here, we analyze images and DTMs of the Slipher, Racah X-1, Mandel'shtam-1, Feoktistov, Simpelius-1, and Oppenheimer F lobate scarps. Parameters in fault dislocation models are iteratively varied to provide best fits to DTM topographic profiles to test previous interpretations that the observed landforms are the result of shallow, low-angle thrust faults. Results suggest that these faults occur from the surface down to depths of hundreds of meters, have dip angles of 35-40 degrees , and have typical maximum slips of tens of meters. These lunar scarp models are comparable to modeled geometries of lobate scarps on Mercury, Mars, and asteroid 433 Eros, but are shallower and approximately 10 degrees steeper than geometries determined in studies with limited Apollo-era data. Frictional and rock mass strength criteria constrain the state of global differential stress between 3.5 and 18.6 MPa at the modeled maximum depths of faulting. Our results are consistent with thermal history models that predict relatively small compressional stresses that likely arise from cooling of a magma ocean.

Here, we investigate the response of vegetation to the 8.2 ka event, an abrupt climate oscillation in the North Atlantic region. High-resolution intervals of pollen data from radiocarbon-dated sediment cores from Rocky Pond, MA (ca. 8.8-7.2 ka; approximately 25 yrs/cm) and Davis Pond, MA (ca. 9.0-7.0ka; approximately 20 yrs/cm) show individualized changes in pollen taxa around the time of the 8.2 event. At ca. 8.0 ka, the pollen record from Rocky Pond shows a peak in pine (Pinus) pollen abundance and a corresponding low in oak (Quercus) pollen abundance, whereas the pollen record from Davis Pond shows high beech (Fagus) and low oak pollen abundances. A comparison of Rocky Pond with the pollen records from nearby Crooked Pond and Blood Pond show consistent changes in oak, pine, hemlock (Tsuga), beech and ragweed (Ambrosia) pollen abundances around 8.2 ka. A decline in the abundance of ragweed pollen at these three ponds is consistent with inferences for an interval of open landscape within the region prior to ca. 8.0 ka. Pollen influx data from Rocky Pond reveal a peak in pollen deposition rates (in both total pollen and some individual taxa) at ca. 8.2 ka, while the pollen influx from Davis Pond shows little to no change. Neither Rocky Pond nor Davis Pond records a singular, prominent change in pollen taxa specifically attributable to the 8.2 ka event. Multiple changes in individual pollen taxa within 100 years of the 8.2 ka event may indicate minimal community turnover associated with the event, while differences between ponds may result from the coastal location of Rocky Pond relative to the interior Davis Pond.

We constructed SDMs for 30 stream fishes of Maryland, USA, using watershed attributes as environmental variables and presence/absence as species responses. SDMs showed substantial agreement between observed and predicted values for 17 species. Most important variables were natural attributes (e.g., ecoregion, watershed area, latitude/longitude); land cover (e.g., %impervious, %row crop) was important for three species. Focused analyses on four representative species (central stoneroller, creek chub, largemouth bass, and white sucker) showed the probability of presence of each species increased non-linearly with watershed area. For these species, SDMs built to predict absent, low, and high densities were similar to presence/absence predictions but provided probable locations of high densities (e.g., probability of high-density creek chub decreased rapidly with watershed area). We applied SDMs to predict suitability of watersheds within the study area for each species. Maps of suitability and the environmental and species response relationships can help develop better management plans.

The Rancheria Basin in northern Colombia contains the record of such activity in a thick Paleogene clastic wedge overridden by the large, northwest-verging Cerrejon thrust sheet. A cored, shallow borehole located near the tip of the thrust sheet was key to document the angle of the fault, timing of deformation, and to identify units in both, hanging wall and footwall blocks. In the northern Rancheria basin, the shallow-dipping Cerrejon thrust places volcaniclastic rocks of Triassic-Jurassic age over lower Eocene conglomerate and mudstone, and a 1-km-thick coal-bearing, reptile fossil-rich, clastic wedge of late Paleocene age. A 350-m-deep stratigraphic cored-borehole, drilled in the hanging wall of the Cerrejon thrust and 500 m inboard of the fault trace, crossed the Cerrejon thrust as predicted by surface mapping. Our analyses from the core indicate that Middle Jurassic volcaniclastic rocks (U/Pb volcanic zircon ages) are thrust with a shallow dip of approximately 10 degrees over lower Eocene coal-bearing strata (palynological ages). These findings constrain NW-SE shortening values to be at least 20 kms along the Cerrejon thrust. Sandstone petrography and detrital zircon geochronology in the Middle Jurassic volcaniclastic succession constrain the history of the nearly 7-km thick Jurassic sequence and Paleozoic strata in this area. Sedimentological and provenance analysis in the lower Eocene succession crossed by the borehole indicate that coal-bearing strata become younger eastward as predicted by tilting of the blocks in response to coeval arc-continent collision along the Caribbean margin. Provenance data on Eocene strata point to combined supply from both the collisional margin and the onset of inversion of the Jurassic graben.

Since the 1970s, the community has seen large-scale migration to Los Angeles, California, where about half the community now resides. Participant observation and interviews conducted over nine years in both locales, with a focus on interactional patterns in the home domain, indicate that parental language ideologies concerning the relationship between language and place of birth, the nature of multilingual acquisition and impact belief -- the belief that parents have as to the level of control they can exercise over their children's language choices (De Houwer in Studies on language acquisition. Mouton de Gruyter, Berlin, 1999), taken together, disfavor the maintenance of the heritage language. In particular, a weak impact belief undermines parents' ability to engage in language interventions in support of San Lucas Quiavini Zapotec. As a result, family-external language intervention factors that promote language shift, such as the school and peer groups, exert great influence. With a substantial number of San Lucas families living in California and their impact on language choices in the home community (Perez Baez in press), family language policy is of great relevance to the survival prospects of San Lucas Quiavini Zapotec not only in diaspora but also in the home community.

This paper comprises a description and three-dimensional morphometric analysis of new carpals from at least one other individual at Liang Bua attributed to H. floresiensis: a right capitate and two hamates. The new capitate is smaller than that of LB1 but is nearly identical in morphology. As with capitates from extant apes, species of Australopithecus, and LB1, the newly described capitate displays a deeply-excavated nonarticular area along its radial aspect, a scaphoid facet that extends into a J-hook articulation on the neck, and a more radially-oriented second metacarpal facet; it also lacks an enlarged palmarly-positioned trapezoid facet. Because there is no accommodation for the derived, palmarly blocky trapezoid that characterizes Homo sapiens and Neandertals, this individual most likely had a plesiomorphically wedge-shaped trapezoid (like LB1). Morphometric analyses confirm the close similarity of the new capitate and that of LB1, and are consistent with previous findings of an overall primitive articular geometry. In general, hamate morphology is more conserved across hominins, and the H. floresiensis specimens fall at the far edge of the range of variation for H. sapiens in a number of metrics. However, the hamate of H. floresiensis is exceptionally small and exhibits a relatively long, stout hamulus lacking the oval-shaped cross-section characteristic of human and Neandertal hamuli (variably present in australopiths). Documentation of a second individual with primitive carpal anatomy from Liang Bua, along with further analysis of trapezoid scaling relative to the capitate in LB1, refutes claims that the wrist of the type specimen represents a modern human with pathology. In total, the carpal anatomy of H. floresiensis supports the hypothesis that the lineage leading to the evolution of this species originated prior to the cladogenetic event that gave rise to modern humans and Neandertals.

The platform has an areal extent of approximately 90 km (super 2) and formed in a convergent tectonic setting (backarc) under a tropical climatic regime. The attached platform formed as part of a discontinuously rimmed shelf along the Caribbean side of the Isthmus of Panama and consisted of mixed carbonates and siliciclastics. Based on field relations and strontium-isotope stratigraphy, three depositional sequences were identified in the near-surface deposits of the uplifted platform. A Miocene to late Pliocene lithic sandstone unit (sequence 1, Old Bank Formation) forms the foundation of the platform. Coral-rich limestone and coral-rich siliciclastic units were deposited during both the late Pliocene (sequence 2, Isla Colon Formation) and early Pleistocene (sequence 3, Urraca Formation). In sequences 2 and 3 the sediment composition and fauna show distinct differences between the windward and leeward sides of the platform, with the main lithologic variable being the amount of siliciclastic sediment that was admixed with the biogenic carbonate sediments. The siliciclastic deposits (mud rich) in sequences 2 and 3 exhibit lower permeability and relatively minor diagenetic modification, and they lack major karst features. Conversely, the more carbonate-rich deposits are well cemented and strongly affected by meteoric dissolution and karstification. This facies-selective dissolution occurred when middle Pleistocene regional uplift exposed the platform to a tropical climate with high rainfall. Earthquakes and associated uplift of the platform over the past approximately 1 Myr intensely fractured the limestone. Fracture porosity has contributed to rapid infiltration of meteoric water and pervasive dissolution that resulted in numerous vertical sinks as well as an extensive network of horizontal conduits. A large, incised channel feature connects several of the pre-existing caves and conduits. The Colon platform limestone is a product of an equatorial humid carbonate system and is of size similar to platforms of Oligo-Miocene age near Malaysia (Sarawak), Indonesia, and farther north in the South China Sea.

The models differed in scope and complexity and used different input data, but all had been applied to evaluate human impacts on discharges to the Patuxent River or to the Chesapeake Bay. We compared predictions to observations of average annual, annual time series, and monthly discharge leaving three basins. No model consistently matched observed discharges better than the others, and predictions differed as much as 150% for every basin. Models that agreed best with the observations in one basin often were among the worst models for another material or basin. Combining model predictions into a model average improved overall reliability in matching observations, and the range of predictions helped describe uncertainty. The model average was not the closest to the observed discharge for every material, basin, and time frame, but the model average had the highest Nash-Sutcliffe performance across all combinations. Consistently poor performance in predicting phosphorus loads suggests that none of the models capture major controls. Differences among model predictions came from differences in model structures, input data, and the time period considered, and also to errors in the observed discharge. Ensemble watershed modeling helped identify research needs and quantify the uncertainties that should be considered when using the models in management decisions.

Sixty Mars profiles have been assessed and a summary of their morphologic characteristics compiled. Measurements collected quantified the symmetry of the feature, the curvature of the crest, flank slopes, width, height and several comparative ratios. Results show that small TARs have physical characteristics generally similar to measurements obtained from lower resolution images of Mars. The HiRISE image data allow for much improved sampling along each feature; the improved resolution reveals relatively few features not seen in earlier studies, but is well suited for topographic sampling. Measured TAR profiles, when scaled by the width of the feature, can be compared to similarly scaled profiles for terrestrial dunes and megaripples. Abstract Copyright Published 2012.

This investigation focused on the biological processes that will provide the first steps in understanding the cryobiology of whole coral fragments. Coral fragments are a partnership of coral tissue and endosymbiotic algae, Symbiodiniumsp., commonly called zooxanthellae. These data reflected their separate sensitivities to chilling and a cryoprotectant (dimethyl sulfoxide) for the coral Pocillopora damicornis, as measured by tissue loss and Pulse Amplitude Modulated fluorometry 3weeks post-treatment. Five cryoprotectant treatments maintained the viability of the coral tissue and zooxanthellae at control values (1M dimethyl sulfoxide at 1.0, 1.5 and 2.0h exposures, and 1.5M dimethyl sulfoxide at 1.0 and 1.5h exposures, P>0.05, ANOVA), whereas 2M concentrations did not (P0.05, ANOVA), but it did not protect against the loss of zooxanthellae (P<0.05, ANOVA). The zooxanthellae are the most sensitive element in the coral fragment complex and future cryopreservation protocols must be guided by their greater sensitivity.

Modulation of the EPTG by TSI is also shown to exist, in variable ways, for each of the four seasons. Interpretation of the positive relationship between the TSI and EPTG indices suggests that solar-forced changes in the EPTG may represent a hemispheric-scale relaxation response of the system to a reduced Equator-to-Pole temperature gradient, which occurs in response to an increasing gradient of incoming solar insolation. Physical bases for the TSI-EPTG relationship are discussed with respect to their connections with large-scale climate dynamics, especially a critical relationship with the total meridional poleward energy transport. Overall, evidence suggests that a net increase in the TSI, or in the projected solar insolation gradient which reflects any net increase in solar radiation, has caused an increase in both oceanic and atmospheric heat transport to the Arctic in the warm period since the 1970s, resulting in a reduced temperature gradient between the Equator and the Arctic. We suggest that this new interpretative framework, which involves the extrinsic modulation of the total meridional energy flux beyond the implicit assumptions of the Bjerknes Compensation rule, may lead to a better understanding of how global and regional climate has varied through the Holocene and even the Quaternary (the most recent 2.6 million years of Earth's history). Similarly, a reassessment is now required of the underlying mechanisms that may have governed the equable climate dynamics of the Eocene (35-55 million years ago) and late Cretaceous (65-100 million years ago), both of which were warm geological epochs. This newly discovered relationship between TSI and the EPTG represents the "missing link" that was implicit in the empirical relationship that Soon (2009) recently demonstrated to exist between multi-decadal TSI and Arctic and North Atlantic climatic change.

AN - 1282840005; 23340579 AB - Nearly 500 alkaloids, representing over 20 structural classes, have been identified from the skin of neotropical poison frogs (Dendrobatidae). These cutaneous compounds, which are derived from arthropod prey of the frogs, generally are believed to deter predators. We tested the red imported fire ant (Solenopsis invicta) for toxicosis following contact with 20 alkaloids (12 structural classes) identified from dendrobatids or other anurans. Individual ants forced to contact the dried residues of 13 compounds exhibited convulsions and/or reduced ambulation. We estimated the cutaneous concentrations of several compounds based on their reported recoveries from skin extracts of free-ranging frogs and our measurements of the skin surface areas of museum specimens. Pumiliotoxin 251D exhibited contact toxicity below its estimated cutaneous concentration in the Ecuadorian frog, Epipedobates anthonyi, an observation consistent with the hypothesized role of this compound in anuran chemical defense. Our results and those of a previous study of mosquitoes indicate that some anuran skin compounds function defensively as contact toxins against arthropods, permeating their exoskeleton.

AN - 1273437084; 22979917 AB - The search for novel approaches to establishing ecological baselines (reference conditions) is constrained by the fact that most ecological studies span the past few decades, at most, and investigate ecosystems that have been substantially altered by human activities for decades, centuries, or more. Paleobiology, archeology, and history provide historical ecological context for biological conservation, remediation, and restoration. We argue that linking historical ecology explicitly with conservation can help unify related disciplines of conservation paleobiology, conservation archeobiology, and environmental history. Differences in the spatial and temporal resolution and extent (scale) of prehistoric, historic, and modern ecological data remain obstacles to integrating historical ecology and conservation biology, but the prolonged temporal extents of historical ecological data can help establish more complete baselines for restoration, document a historical range of ecological variability, and assist in determining desired future conditions. We used the eastern oyster (Crassostrea virginica) fishery of the Chesapeake Bay (U.S.A.) to demonstrate the utility of historical ecological data for elucidating oyster conservation and the need for an approach to conservation that transcends disciplinary boundaries. Historical ecological studies from the Chesapeake have documented dramatic declines (as much as 99%) in oyster abundance since the early to mid-1800 s, changes in oyster size in response to different nutrient levels from the sixteenth to nineteenth centuries, and substantial reductions in oyster accretion rates (from 10 mm/year to effectively 0 mm/year) from the Late Holocene to modern times. Better integration of different historical ecological data sets and increased collaboration between paleobiologists, geologists, archeologists, environmental historians, and ecologists to create standardized research designs and methodologies will help unify prehistoric, historic, and modern time perspectives on biological conservation. ©2012 Society for Conservation Biology.

Several studies have argued that important changes occurred in the hydrological cycle during the PETM, but results have been inconsistent, ranging from global increases in humidity to drier conditions. Changes in paleosols during the PETM in the southeastern Bighorn Basin document major drying during the body of the event. Paleosol changes also suggest transitional episodes of climate change that both preceded and followed the PETM. Qualitative, semi-quantitative, and fully quantitative analyses of a approximately 70 m thick interval of paleosols provide a high-resolution record of changes in soil moisture and precipitation. Those changes are compared to changes in temperature determined from delta (super 18) O values of tooth enamel from the mammal Coryphodon. A distinct shift to drier soils occurred just prior to the PETM, a conclusion that is consistent with previous observations that warming began before the onset of the negative carbon isotope excursion associated with the PETM. Paleosols show a progressive drying trend into the lower part of the PETM and become even drier in the upper part of the body of the PETM. Purple-red paleosols that appear during the recovery phase of the PETM indicate wetter soils, although they are better drained than paleosols below the onset. The purple-red paleosols continue for approximately 15 m above the recovery and indicate that wetter soil conditions persisted after the recovery. It is not clear whether changes in the paleosols that preceded and followed the PETM reflect global forcing factors like orbital cycles or release of carbon that lacks an isotopic label; however, such mechanisms would provide a unifying explanation for shifts seen in continental and marine environments.

Taxonomic similarities between the composition of modern assemblages and fossil samples are the basis of reconstructing paleoclimates and paleoenvironments. Surface sediment samples reflect a time-averaged accumulation of pollen spanning several years or more. Due to experimental constraints, modern pollen rain samples are generally collected over shorter timeframes (1-3 years) and are therefore less likely to capture the full range of natural variability in pollen rain composition and abundance. This potentially biases paleoenvironmental interpretations based on modern pollen rain transfer functions. To determine the degree to which short-term environmental change affects the composition of the aerial pollen flux of Neotropical forests, we sampled ten years of the seasonal pollen rain from Barro Colorado Island, Panama and compared it to climatic and environmental data over the same ten-year span. We establish that the pollen rain effectively captured the strong seasonality and stratification of pollen flow within the forest canopy and that individual taxa had variable sensitivity to seasonal and annual changes in environmental conditions, manifested as changes in pollen productivity. We conclude that modern pollen rain samples capture the reproductive response of moist tropical plants to short-term environmental change, but that consequently, pollen rain-based calibrations need to include longer sampling periods (> or =7 years) to reflect the full range of natural variability in the pollen output of a forest and simulate the time-averaging present in sediment samples. Our results also demonstrate that over the long-term, pollen traps placed in the forest understory are representative samples of the pollen output of both canopy and understory vegetation. Aerial pollen traps, therefore, also represent an underutilized means of monitoring the pollen productivity and reproductive behavior of moist tropical forests.

In contrast to traditional interpretations, according to which this genus is considered a solitary form, the study of topotypes from the type locality of the type species of the genus P. mammiliformis Duncan shows that it has the capability to form colonial reptoid and subplocoid to subfasciculate clumps in later stages of ontogeny. The genus Podoseris is characterized by septal and thecal structures which are similar to the kinds seen in the haplaraeids. Regarding morphological features of its solitary and colonial stages, this genus corresponds to, e.g. Rhizangia Milne Edwards & Haime, and Brachyphyllia Reuss.

The Satpura-Maikal landscape is classified as a global-priority Tiger Conservation Landscape (TCL) due to its potential for providing sufficient habitat that will allow the long-term persistence of tigers. We found that the tiger meta-population in the Satpura-Maikal landscape has high genetic variation and very low genetic subdivision. Individual-based Bayesian clustering algorithms reveal two highly admixed genetic populations. We attribute this to forest connectivity and high gene flow in this landscape. However, deforestation, road widening, and mining may sever this connectivity, impede gene exchange, and further exacerbate the genetic division of tigers in central India. The Satpura-Maikal landscape is a global-priority Tiger Conservation Landscape (TCL) that supports 12% of India's tiger population and comprises 13% of tiger habitat in India. Here, we present the findings of our study of the spatial genetic structure and connectivity of tiger populations in Satpura-Maikal landscape of central India. We found that this tiger meta-population has high genetic variation and very low genetic subdivision due to forest connectivity and high gene flow. However, infrastructural development and exploitation of natural resources poses a threat to the survival of this meta-population.

The proposed mission is based on the Mars Science Laboratory (MSL) rover and would be delivered using the same basic Entry Descent and Landing (EDL) system. The SDT recommended threshold EDL requirements that include access to + or -30 degrees latitude and elevation up to -0.5 km in order to ensure access to a range of high priority sites. Landing site selection criteria for Mars 2020 are driven by objectives of both in situ science investigations and returned sample science, and are broadly consistent with the findings of E2E-iSAG. Importantly, the merit and properties of compelling community proposed landing sites can define improvements in EDL capability for accessing unprecedented science potential tailored to mission with a diverse set of scientific goals including caching samples for possible return to Earth. Relatively dust-free sites of high interest to astrobiological and sample caching studies are most typically found in places with steep slopes and or present-day wind erosion and these sites can be difficult to reach with as-flown MSL EDL system landing ellipses. Hence, the SDT concludes that range trigger should be a threshold EDL capability and strongly proposes inclusion of Terrain Relative Navigation as highest priority baseline so as to help ensure access to a sufficient number of high priority sites. Terminal Hazard Avoidance has less impact on access to unique classes of sites and is considered enhanced capability Because Mars 2020 would be the first mission to cache samples for possible return to Earth it requires a landing site selection process differing from those previous and that acknowledges the potential legacy associated with returned samples. It is therefore crucial to involve the broad science community in proposing and evaluating candidate sites for the 2020 rover, thereby leading to science community consensus on the optimal site for meeting the mission goals. An effort to identify and evaluate candidate landing sites is expected to begin in earnest in 2014.

Data are from four sources: the Smithsonian Institution, Witham (2005), CRED EM-DAT and Munich RE. The data were combined and formatted, with a weighted average fatality figure used where more than one source reports an event; the former two databases were weighted twice as strongly as the latter two. More fatal incidents are contained within our database than similar previous works; approximately 46% of the fatal incidents are listed in only one of the four sources, and fewer than 10% are in all four. 278,880 fatalities are recorded in the database, resultant from 533 fatal incidents. The fatality count is dominated by a handful of disasters, though the majority of fatal incidents have caused fewer than ten fatalities. Number and empirical probability of fatalities are broadly correlated with VEI, but are more strongly influenced by population density around volcanoes and the occurrence and extent of lahars (mudflows) and pyroclastic density currents, which have caused 50% of fatalities. Indonesia, the Philippines, and the West Indies dominate the spatial distribution of fatalities, and there is some negative correlation between regional development and number of fatalities. With the largest disasters removed, over 90% of fatalities occurred between 5 km and 30 km from volcanoes, though the most devastating eruptions impacted far beyond these distances. A new measure, the Volcano Fatality Index, is defined to explore temporal changes in societal vulnerability to volcanic hazards. The measure incorporates population growth and recording improvements with the fatality data, and shows prima facie evidence that vulnerability to volcanic hazards has fallen during the last two centuries. Results and interpretations are limited in scope by the underlying fatalities data, which are affected by under-recording, uncertainty, and bias. Attempts have been made to estimate the extent of these issues, and to remove their effects where possible. The data analysed here are provided as supplementary material. An updated version of the Smithsonian fatality database fully integrated with this database will be publicly available in the near future and subsequently incorporate new data.

Herein, we present new records of a very diverse Neotropical vertebrate fauna from the Castilletes (early to middle Miocene) and Ware (Pliocene) Formations. The predominant deposits of these Formations are shallow marine environments, and fluvio-deltaic environments with large freshwater reservoirs that strongly contrast with the dry climate and xerophytic vegetation of La Guajira peninsula today. The most relevant paleontological findings from marine environments are numerous morphospecies of sharks, rays and catfish; while from fluvio-deltaic environments are dogtooth tetras and piranhas (today only distributed in distant areas like the Amazon and Orinoco basins) fresh water turtles, snakes and one of the oldest records of Crocodylus in the Americas. Additionally, the mammal assemblage comprises Xenarthrans that includes Megatheriid and nothrotheriid sloths and the cingulates, Glyptodontinae and Pampatheriidae. Rodents are represented by Chapalmatherium, cf. Neoepiblema and Paramyocastor. Indigenous South American ungulates include horse-like protherotheriids, rhino-like toxodonts and astrapotheres. North American migrants include deer-like Protoceratidae and raccoon-like Procyonidae. The wide fossil record from La Guajira peninsula provides essential information to understand biological aspects like the evolution and biogeography of the Neogene fauna of America. Also, geological aspects like the formation of Panama isthmus and the rise of the Andes cordillera; and local ecological aspects like changes in the level of the sea and recent desertification events.

Due to its low solubility, metacinnabar has historically been considered an insignificant source of Hg to the aqueous environment. Our previous work has shown that bacterial colonization of metacinnabar incubated in the shallow sediments of the Hg-contaminated East Fork Poplar Creek (Oak Ridge, TN) is dominated by genera known to use reduced sulfur compounds as electron donors during growth. Based on 16S rRNA pyrosequencing, Thiobacillus thioparus, an obligate autotrophic neutrophilic sulfur oxidizer, is among the most abundant colonizers. Here we show that T. thioparus incubated aerobically in the presence of metacinnabar and thiosulfate (0.1-20 mM) results in substantial metacinnabar dissolution and release of Hg. Upon reaction, sulfate concentrations are higher than can be attributed to oxidation of thiosulfate alone, yet aqueous Hg(II) concentrations remain below detection limit. We show that in the presence of live cultures of T. thioparus aqueous Hg(II) released following HgS dissolution is rapidly volatilized forming Hg(0). In control incubations (media with thiosulfate and metacinnabar, and no viable cells) thiosulfate concentrations correlate with levels of dissolved Hg(II), suggesting that thiosulfate, a strong Hg-binding ligand, abiotically induces HgS dissolution. T. thioparus posseses genes involved in the Mer detoxification pathway, and we are currently investigating mer expression in this system. These findings have important implications for environmental Hg cycling, highlighting the unappreciated potential of Hg release from assumed permanent solid-phase Hg sinks. It further introduces new pathways for solid-phase Hg to enter the global atmospheric mercury pool.

The middle Miocene climatic optimum (MMCO, 15-17 Ma) is one of the best analogues to our ongoing global warming as it occurred during the long-term global climatic cooling trend we have had for the past 20 Ma. Any paleobiological data retrieved from this time period is thus valuable for understanding current climatic perturbations. We report the recent discovery of an outstandingly preserved middle Miocene leaf assemblage from the Pedro-Miguel Formation, in the basin of the Panama Canal. This leaf assemblage comprises at least fifteen morphotypes of (nearly) whole-leaf cuticles, some of which have been assigned to typical Neotropical families including Fabaceae, Anacardiaceae and Moraceae. We interpret that the rapid burial of the forest litter in relation to surrounding volcanic activity favored the preservation of intact cuticles and cellular details in these leaves, and provides a unique opportunity to combine leaf anatomical and biochemical data for inferring past forest ecology. The visualization of species-specific stomatal pore, epidermal and mesophyll cell size, in addition to carbon isotopic signatures can be used to infer primary leaf physiological traits such as water use efficiency, mesophyll conductance, and estimate CO (sub 2) levels during the Middle Miocene Climatic Optimum from this Neotropical setting.

They are first known from the Mid-Jurassic ( approximately 160 Ma.) and rapidly diversified worldwide during the Cretaceous ( approximately 146 to 66 Ma.). Since then, crabs have exploded in form and function, resulting in the incredible morphological diversity seen among the more than approximately 9,000 fossil and extant species. Despite the large disparity of their body plans, various molecular, morphological and spermatological studies have shown that Brachyura is a monophyletic group, sister to Anomura (i.e hermit crabs and allies). Nevertheless, the oldest brachyurans are anatomically very different from the rest of higher crab clades, obscuring their phylogenetic relationships. Previous and recent field works in Early Cretaceous rocks of Santander, Colombia (Zapatoca, from 1983 to 2012; San Vicente de Chucuri, 2013) have yielded more than 400 specimens of a dozen ancient brachyuran crab species (Luque et al., in progress). Based on synthetic and cladistic classifications, some of these taxa cannot be placed in any currently recognized fossil or extant family. Their combinations of plesiomorphic and synapomorphic traits indicate that the early evolution of brachyuran crabs is more complex than currently envisioned. Among other recent findings are some of the oldest known members of many families and superfamilies of 'podotreme' crabs (e.g. Homoloida, Raninoida), and even the earliest record of 'higher' true crabs (i.e. Eubrachyura). These findings challenge current spatio-temporal and phylogenetic hypotheses, and suggest a) that several Colombian crab higher taxa have Pantropical distributions but with a high degree of endemism of families and genera, b) a tropical South American origin for many clades previously considered to have originated in higher latitudes, and c) that the Neotropics have acted as a hotspot of diversity for crustaceans through time.

Will TRFs collapse? The fossil record can inform us about that. Our compilation of 5,998 empirical estimates of temperature over the past 120 Ma indicates that tropics have warmed as much as 7 degrees C during both the Mid-Cretaceous and the Paleogene. We analyzed the paleobotanical record of South America during the Paleogene and found that the TRF did not expand toward temperate latitudes during global warm events, even though temperatures were appropriate for doing so, suggesting that solar insolation can be a constraint on the distribution of the tropical biome. Rather, a novel biome, adapted to temperate latitudes with warm winters, developed south of the tropical zone. The TRF did not collapse during past warmings; on the contrary, its diversity increased. The increase in temperature seems to be a major driver in promoting diversity.

For stasis, If N, the number of individuals, is constant at each station , then, S, species richness and H, the information function, will also be constant. Because rare species appear at only one or a few stations, as N and S are accumulated by station, the accumulated total number of species in a traverse will exceed the number at each station. The Log series distribution serves as a null model for this situation. For a Log series S increases with accumulating N at a semi-log rate, but H remains constant. The regression H=beta (sub 0H) +beta (sub 1H) lnN expresses the relationship of H with accumulating N where beta (sub 0H) is a constant and beta (sub 1H) is the regression coefficient expressing the rate of change between-station (habitat) diversity. At stasis beta (sub 1H) =0 and there is no biodiversity gradient. When beta (sub 1H) is positive S accumulates at a higher rate than for a Log series and there is a positive gradient. Consequently, although two areas may contain the same number of species per station, the area with higher between-station diversity will contain more overall species. We divided the deep-sea into two categories: 200-1500 m and >1500 m. The beta (sub 1H) coefficient was examined for benthic foraminifera between 333 stations within 49 communities from New Zealand, the South Atlantic Ocean, Gulf of Mexico, Norwegian Sea and the Arctic Ocean. beta (sub 1H) -diversity exhibits no evidence of regional differences. Instead, higher values at shallower depths are observed world-wide. At depths >1500 m the average beta (sub 1H) is zero, indicating stasis or no biodiversity gradient. This difference in beta (sub 1H) -diversity explains why, despite species richness often being greater per station at deeper depths, the total number of species is greater at shallower depths. The greater number of communities and higher rate of evolution resulting in shorter species durations at shallower depths is also consistent with higher beta (sub 1H) values.

The relative extent of perturbations to the Everglades ecosystem by human activities (e.g., beginning of agriculture, canal construction) versus natural events (e.g., hurricanes, droughts) has been debated. This study compares the timing of perturbations in the records of preserved microbiotas and physical conditions to known human and natural events over the past 120 years to infer their relative strengths. Six sediment cores taken in 2002 from four areas of Florida Bay (near the mainland, the central bay and near the Gulf of Mexico) were dated with (super 210) Pb and analyzed for proxy variables of water quality and environmental change. For each variable, the number of sediment samples and the cores sampled ranged from 300. We used an adaptation of impulse-response functions, a procedure from signal-processing, to track the responses of the variables to the impulses of the time-dependent shocks or occurrences of disruptive events, both anthropogenic and natural. We were able to identify where larger breaks and smaller perturbations occurred in time within the dated sediment cores. The physical variables did not produce definitive responses but the foraminiferal and diatom assemblages did. We used the biotic variables alone to identify six times of major breaks and perturbations that correspond in timing to the following documented events: 1) 1906-1910 construction of the Flagler Railroad; 2) 1926-1935 hurricanes; 3) 1954-1959 strongly negative phases of the El Nino/Southern Oscillation and Pacific Decadal Oscillation, and associated extensive drought events; 4) 1977-1980 negative Atlantic Multidecadal Oscillation and ENSO, strong drought and institution of a Monthly Allocation Plan for controlling water release; 5) 1987-1994 seagrass die-off that began with hot, still conditions; and 6) 1997-1999 seagrass recovery and increased water flow. This study is being continued with new approaches of reducing the number of species in whole assemblages to those that are ecologically meaningful for each event, and testing the hypotheses of the causes of the breaks against what is predicted for each event.

The Mission and Aransas Rivers respectively enter Mission and Copano Bays, and the reserve encompasses other bays as well as the Aransas National Wildlife Refuge. Inflow into Texas estuaries is important in terms of quality of the environment and thus the economy, with various agencies monitoring freshwater input. Since the establishment of the MANERR, living foraminifera have been sampled in many of the secondary and tertiary bays including Copano, Mission, Mesquite, and St. Charles. Abundant and easily sampled, foraminiferal populations provide information about current biotic conditions and then their dead tests accumulate to catalog past environments. The present study focuses on Mission Bay, a small tertiary bay from which foraminifera have never been studied. Cores were taken at four stations along a north-south transect from the mouth of the Mission River to the mouth of the bay, and a total of 14 species were found. Statistical analysis shows that richness and diversity increase and species dominance decreases toward the bay mouth. These population parameters indicate a healthy ecosystem, though a couple of observations are worth noting. First, some dead tests exhibit a distinct yellow discoloration thought to be due to sulfur since yellow minerals are also seen in the sediments. Past research recorded excess barium in the bay, perhaps from barium sulfate muds associated with oil drilling in the area. Shell analysis with laser induced breakdown spectrometry suggests the presence of barium in both living and dead specimens. Second, individuals from two species have dark spots in the stained protoplasm, perhaps from bacterial decay or mineralization. As with many coastal settings, abundant pyrite occurs in sediments as well as in living and dead foraminiferal tests, so the dark spots could be pyrite minerals. This study provides baseline foraminiferal data for future monitoring in the MANERR, and underlines the utility of foraminifera for environmental interpretation in the present as well as the past.

Understanding of, and data from, the diverse collection of geological settings in the Solar System provides a wealth of opportunity for teaching introductory geology. One strong motivation for using this material is to provide students with low-stakes experiences of the scientific process. Since landscapes beyond Earth are less familiar to introductory geology students than those of their home world, they cannot be expected to know as much about them up front. This frees them from concern over having 'the right answer', and instead encourages creative thinking. When asked to assess two (out of nine) labs in a Physical Geology course at Northern Virginia Community College (NVCC), approximately 30% of the students (5 out of 16) chose to comment on the Impact Lab (modeled after material developed by NASA). This lab asked students to create and diagram several craters, calculate the effects of mass and speed on energy released during impact, and think about where in the Solar System they would find craters. There was general consensus that it "was helpful in understanding how craters impact planets and what happens to the ejecta" by being able to "compare visually the different craters we made" and see how "impacts change based on angle and speed." One student specifically commented that it "would have helped even more to compare velocity and angle [of impact] by looking at actual craters on the Moon, Mars, etc". In-class activities and short essay exam questions using maps of other planets encouraged students to think about the lines of evidence for the theory of plate tectonics. Given global maps of volcanism on Venus, thrust faults on Mercury, elevation on Mars, and all of these on Earth, they were asked to determine whether other planets have plate tectonics. In-class activities comparing Earth to Venus and Mercury were used during the Assistant Dean's observation (NVCC); he "liked the activity", which "got [the students] thinking about larger concepts". We encourage geology educators to include extraterrestrial content in their lecture materials, in-class activities, labs, and exam questions, as a way to engage students in critical thinking about geologic concepts and processes, particularly in introductory courses.

Unfortunately, there are very few studies of Early Cretaceous "pre-angiosperm" (Berriasian-Aptian) floras from North America. Here, I use evidence from >40 plant megafossil collections compiled from literature sources and museum collections to understand the diversity and systematic composition of "pre-angiosperm" Early Cretaceous floras from the United States. Collections range from Texas to Montana and Oregon to Arkansas. Geologic evidence indicates a strong latitudinal climate gradient in the western United States as indicated by plant-bearing limestone beds in Texas, vertic paleosols in Nevada and Wyoming, and coals up to 2 meters thick in Montana (and Canada). This gradient may have been paralleled by a shallow and inverted latitudinal diversity gradient. In general, the collections have low species richness (<15 species) regardless of original collection size and facies. However, collections from along the western margin of North America (southern Oregon & northern California) have the highest species richness ( approximately 15-25 species), but these collections represent allochthonous terranes. A variety of plant groups are represented among the species that dominate these collections including Equisetum, ferns, various cycadophytes, Sagenopteris spp., Ginkgo, and several conifer groups.

While these events have been the subject of much interest and study, major questions remain regarding the terrestrial climate and ecosystem structure of northern South America during this interval. We present carbon and oxygen stable isotope records from the uppermost La Victoria through the Baraya (lower) member of the Villavieja Formations from the Mid-Miocene Honda Group in Colombia, including 1) delta (super 18) O (PO (sub 4) , CO (sub 3) ) and delta (super 13) C (CO (sub 3) ) of mammalian bioapatite, 2) delta (super 18) O and delta (super 13) C (CO (sub 3) ) of pedogenic carbonates, and 3) delta (super 18) O (PO (sub 4) ) of fish teeth. The Mid-Miocene ecological structure of the region was affected by the climate changes related to both global trends and the early stages of Andean and Central American uplift, but the details of the extent, timing, and character of these effects has not yet been resolved. A combination of delta (super 18) O (PO (sub 4) ) measurements from endotherm (mammalian) and ectotherm (fish) bioapatite enable mean annual temperature (MAT) estimates. Our data indicate MAT between 30-34 degrees C. These reconstructions are sensitive to the model parameterization; however, independent lines of evidence can help to more firmly resolve these parameters. delta (super 18) O (PO (sub 4) ) is similar between the lowermost and uppermost sites sampled in the sequence, which suggests that MAT was stable for the Honda Group over this interval. Seasonality is another very important climate factor in terrestrial ecosystems, as the same MAT and mean annual precipitation (MAP) can result in both grasslands and rainforests depending on the amount of seasonal variation. Serial sampling of mammalian tooth enamel provides a useful record of seasonal variability. delta (super 18) O shows very little variation along the length of the mammal teeth, which indicates a climate low in variation in both temperature and the amount of precipitation. delta (super 13) C indicates that the diets of the large mammalian herbivores were comprised of plants from a somewhat open, but humid, vegetation structure. These data help to fill gaps in our knowledge of low latitude continental paleoclimate.

Major episodes of fluid-rock interaction attended: 1) eruption/hybabyssal emplacement of igneous protoliths on or near the seafloor at approximately 200 to 150 Ma; and 2) emplacement of the Sierra Nevada batholith at approximately 100 Ma. Early alteration was primarily manifested by wholesale changes of bulk and mineral compositions relative to likely protoliths. It is layer-to-layer in style, producing metavolcanic rocks that vary between sodic, sodic/calcic, potassic, and calcic bulk compositions, as well as veins and mineral zoning. Early veins are transposed or folded, indicating that deformation attended early alteration. Early alteration effects are seen in units 100s of m thick and km along strike. Late alteration is seen primarily as veins with metasomatic envelopes. Vein envelopes are generally much greater in volume than veins. The geometry of late veins and vein envelopes resembles that of fractures and veins in plutons, indicating that late veins are syn-to-post-plutonic. In both early and late veins, epidote-group minerals-in particular, pistacite-to-piemontite solid solutions-record further details of vein-forming (and -modifying) fluid-rock interactions. Of particular interest are the abundances of REE, Mn and Sr in veins and envelopes. Overall, the geochemistry of epidote minerals from veins provides evidence for complex fluids of relatively low salinities, in H (sub 2) O-CO (sub 2) systems that fluctuate in composition over time. This is seen in the products of both early and late alteration. The zoning relationships, microstructures and compositions of epidote-group minerals show that on all scales, at least some mass transport was influenced by fluid properties, including fO (sub 2) , that varied over scales of mu m to km. The geochemistry of metavolcanic host rocks and its veining systems is thus a useful tool in reconstructing the evolution of shallow arc crust throughout its development.

Among angiosperms, biotic dispersal greatly overshadows abiotic mechanisms (wind or aquatic dispersal) in extant Neotropical rainforests. Many important plant families in Neotropical rainforests (e.g. Apocynaceae, Bignoniaceae, Bromeliaceae, Sapindaceae, etc.) include abundant genera with various morphological adaptations for wind dispersal of fruits or seeds, such as wings, accessory hairs, or reduced size. Most of these families have moderate to high levels of plant diversity in extant Neotropical rainforests, where they commonly occupy the upper levels of the canopy. It is still unknown when these groups appeared in the Neotropical fossil record. Thirty-five specimens were collected from the Paleocene of Colombia ( approximately 58-60 Ma). We surveyed the fruit and seed morphology of abundant wind-dispersed angiosperm families and reviewed the related fossil record. Six new species of disseminules with varied adaptations for wind dispersal are documented here. These fossils, representing extinct genera of Ulmaceae, Malvaceae, and other uncertain families, suggest that wind-dispersed fruit and seed syndromes were already common in the Neotropics by about 58-60 My ago, coinciding with the early development of multistratal rainforests. Although the major families known to include most of the winged-dispersed disseminules in extant rainforests are still missing from the Paleogene fossil record of South and Central America, the new fossils imply that disseminules transported via wind currents were a relatively important mechanism of plant evolution and diversification in ancient Neotropical rainforests.

Low lands are extended from the continent to the north part of the peninsula where are interrupted only by three major ranges--Macuira, Jarara and Cocinas. This physiographic configuration makes its connection with the continent, susceptible to any important sea level fluctuation. Therefore, provenance analysis in sedimentary rocks will be a useful tool for identifying those fluctuations. Stratigraphic work in the Castilletes Formation shows major sea level oscillations by lithological and sedimentological changes. In this manner, it is possible to identify any major drop in the global sea level related to the onset of the northern hemisphere glaciation. To understand the Guajira Peninsula desertification is important to consider the global and local context. As part of the local landscape there is the Macuira Range, the highest elevation in the Guajira Peninsula, with 864 meters over the sea level. Due to its localization, in the northernmost portion of the peninsula, and to its southeast-northwest trend, it constitutes an important physiographic barrier for the humid winds coming from the northeast to South America. As consequence, an amazing humid ecosystem has been developed in the Macuira Range. The impact of the Macuira Range is a shadow effect of humidity that could be responsible of the dominating dry climate conditions in the peninsula. Hence, the Macuira Range could be also responsible for the past drastic climate change that Castilletes Formation is showing. As a consequence ages of exhumation and desertification should be correlated. To address this possible explanation I plan to study the exhumation of the Macuira Range using thermochronology. Invertebrate biostratigraphy, vertebrate paleontology, paleobotany and palynology studies are being conducted by paleontologist. Putting together their upcoming results with the stratigraphy, sedimentology, provenance, and thermochronology analyses will allow the better understanding of the dramatic ecological changes that took place during the last few millions years in the Guajira Peninsula.

Alluvial activity included formation of alluvial fans flanking portions of the crater walls. An example includes the upper Peace Vallis fan extending from the northern wall of the crater. Topographic data suggests this fan is part of a larger alluvial accumulation extending into the region explored by the Curiosity rover. Crater statistics in combination with geologic mapping reveal the oldest units in Gale date from the early-to-mid Hesperian and suggest their emplacement began shortly after formation of the crater. The older units likely include the bulk of the deposits associated with the alluvial fans. However, younger ages are also derived for some surfaces, implying a period of geomorphic activity during the later Hesperian or into the Amazonian. Much of the later activity may relate to exhumation as the deposits comprising Mt Sharp retreated to the current, eroded form near the crater center. However, local surfaces on some fans, including portions of the Peace Vallis fan, may reflect a veneer of sediments on the broader fan form. Erosional relief (e.g., required for topographic inversion of relict distributaries) implies approximately 5-10 m surface lowering on these surfaces, consistent with a paucity of craters <30-40 m. Coupled with the absence of pedestal craters or other morphologies pointing to exhumation as the sole cause of late activity, these data suggest late occurring, local alluvial activity on some fans. The small areal extent of the units and differences in surface properties make age determination from small diameter craters difficult. Nevertheless, the timing of possible late alluvial activity in Gale correlates with alluvial activity in Margaritifer Terra hypothesized to result from melting snow. At Peace Vallis, any late deposition appears limited to the upper fan, though sediment contributions to the areas explored by Curiosity cannot yet be ruled out. Regardless, associated water would have drained downslope and could have contributed to development of late diagenetic features observed by Curiosity in the rocks at Yellowknife Bay.

Martian organic carbon has been detected previously in igneous basalts and the carbonates of ALH 84001. Analysis of sealed maskelynite inclusions using in situ techniques including Raman, NanoSIMS, ToFSIMS, STXM and TEM, coupled with whole rock analysis by stepped combustion, GCMS and evolved gas analysis has revealed an inventory of organic compounds containing -CH, -CN, -CNO, -COOH, -CO and aromatic complexes. These are spatially resolved to known inorganic catalysts, i.e. magnetite, pyrite, nickel containing pyrrhotite and clays. Furthermore there is a release of nitrogen containing organics above 600 degrees C, at which temperature delta (super 15) N is approximately +40 ppm. These results show that Mars has an inventory of organic carbon and nitrogen containing molecules that are probably produced through abiological hydrothermal activity.

Thirty molluscan biofacies, inferred to have accumulated in estuarine to outer shelf palaeoenvironments, have been identified and represent both in situ and transported assemblages. Although distributed through the late Neogene succession, most biofacies occur within the Late Pliocene-Early Pleistocene part of the Mangaheia Group. Using the spatial distribution of the different biofacies, we have constructed detailed palaeoenvironmental reconstructions for the Plio-Pleistocene of central Hawke's Bay. The stratigraphic occurrence of particular biofacies has been primarily controlled by relative sea-level positions and variations in sediment input during high-frequency glacio-eustatic sea-level oscillations. The distribution of biofacies reflects proximity to contemporaneous shorelines, localised sources of carbonate sediment or dominance of siliciclastic sedimentation, and records the interplay between tectonic and eustatic drivers of relative sea-level change.

BBCP cores are being used to develop high-resolution proxy records of the Paleocene-Eocene Thermal Maximum (PETM) and Eocene Thermal Maximum 2 (ETM2) hyperthermal events. These events are short-term, large magnitude global warming events associated with extreme perturbations to the earth's carbon cycle. Although the PETM and ETM2 occurred approximately 55-52 million years ago, they are analogous in many ways to modern anthropogenic changes to the carbon cycle. By applying various sedimentological, geochemical, and palynological methods to the cores, we hope to better understand what caused these events, study the biogeochemical and ecological feedbacks that operated during them, and reveal precisely how they impacted continental environments. Core recovery was >98% in all holes and most drilling was carried out without fluid additives, showing that continuous coring of continental smectitic deposits like these can be achieved with minimal risk of contamination to molecular biomarkers. Cores were processed in the Bremen Core Repository where the science team convened for 17 days to carry out data collection and sampling protocols similar to IODP projects. Initial results show that the weathered horizon extends to as much as approximately 30 m below the surface and variations in magnetic susceptibility within the cores record an interplay between grain size and pedogenesis. Previous investigations of outcrops near the BBCP drill sites allow detailed evaluation of the effects of weathering on common proxy methods. Studies of lithofacies, organic geochemistry, stable isotope geochemistry, calibrated XRF core scanning, paleomagnetics, and palynology are underway and will represent the highest resolution and most integrated proxy records of the PETM from a continental setting yet known. An extensive outreach program is in place to capitalize on the educational value associated with the Bighorn Basin's unusually complete record of Phanerozoic earth history.

Based on the report, it was proposed that melt may be neutrally or negatively buoyant in the deep mantle. Nomura et al. [2011] attributed the iron partitioning change to a sharp high-spin to low-spin change in iron, which was found in their measurements on a Fe-diluted (5%) Mg-silicate glass at a similar pressure. However, Andrault et al. [2012] found no sharp change in iron partitioning between silicate melt and minerals in an Al-bearing system up to 120 GPa. We measured the electronic configuration of iron in two different iron-rich (20%) Mg-silicate glasses at high pressure and 300 K in the diamond-anvil cell combined with X-ray Emission Spectroscopy (XES) and Nuclear Forward Scattering (NFS): Al-free glass up to 135 GPa and Al-bearing glass up to 93 GPa. We found no sharp changes in the spin state of iron up to our maximum pressure. Instead, the population of low-spin iron increases gradually from 1 bar in both glasses, but significant population of iron still remains high spin (40-50%) even at 90-135 GPa. Our observation is consistent with the expectation of gradual response of disordered systems to compression due to the existence of diverse coordination environments for iron in the glasses and continuous structural adjustment of the disordered system with pressure. If our results on Mg-silicate glasses can provide some insights for iron in mantle melts, the spin transition in iron should be gradual and further smeared out at the high temperatures of mantle melts [Sturhahn et al., 2005], and therefore unlikely to induce a sharp change in iron partitioning in the deep mantle.

Such solids are preserved in chondrites as calcium-aluminum-rich inclusions (CAIs) and amoeboid olivine aggregates (AOAs). Evidence for the original evaporation and condensation is preserved mainly in the form of characteristic chemical and isotopic signatures, but rarely in the physical properties (e.g. textures) of the objects. In contrast, evidence for repeated melting and re-heating is everywhere in the petrology of most CAIs and AOAs. Advances in the analytical precision of mass spectrometry (MS), especially secondary ionization (SIMS), thermal ionization (TIMS), and inductively-coupled plasma (ICP-MS), now permit extraordinary time resolution of early solar system events that are recorded in the petrologic properties of CAIs and AOAs. Pb-Pb ages of CAIs yield a precision of < 500 Ka. ICP-MS measurements of the (super 26) Mg- (super 26) Al isotope system demonstrate that the primary fractionation (presumably via condensation) of Al from Mg took place within 20 Ka. SIMS determinations of internal (super 26) Mg- (super 26) Al extinct isochrons confirm that CAI precursors formed within a very short time consistent with that determined by ICP-MS, but remelting and reprocessing of CAIs continued for at least 200 Ka and possibly as long as 600 Ka. The time resolution of such SIMS internal isochrons is now better than 50 Ka. The challenge now is to identify the nature of the processes that are recorded in this chronology. For example, the original fractionation event that made the CAI precursors apparently was singular and of short duration whereas remelting occurred as a result of a process that happened repeatedly over 200 Ka or more. Nor is it clear if the formation of Wark-Lovering rims was a singular event affecting all CAIs simultaneously or a repeating event over time. Finally, there is as yet no anchor that ties Solar chronology with CAI chronology. One recent suggestion is that the last (or nearly so) FU-Orionis flare in the early Sun was responsible for making the generation of CAIs we now see, but earlier generations were destroyed. Such linking of solar processes and chronology with nebular products is a major challenge for the future.

Basaltic arc magmas have been proposed to achieve calc-alkaline affinity through either high magmatic H (sub 2) O, which delays the onset of plagioclase crystallization, or high magmatic fO (sub 2) , which enhances the onset of magnetite crystallization, or both. The relative importance of H (sub 2) O, fO (sub 2) , and magmatic bulk composition in generating calc-alkaline magma series, however, is not yet clearly resolved. Here, we present new measurements of the oxidation state of Fe (expressed as Fe (super 3+) /Sigma Fe ratio) in olivine-hosted melt inclusions from basaltic arc volcanoes in the Mariana and Aleutian arcs, acquired using X-ray Absorption Near Edge Structure spectroscopy. These volcanoes span a range of calc-alkaline affinity, with THI ranging from 0.7 to 1.2 (THI = Tholeiitic Index, 1 is more tholeiitic [1]). Measured Fe (super 3+) /Sigma Fe ratios range on average from 0.23-0.28 in the Marianas, and from 0.20-0.28 in the Aleutians, which are uniformly more oxidized than more tholeiitic basaltic glasses from the Mariana trough back-arc basin (THI=1.4; Fe (super 3+) /Sigma Fe=0.15-0.18) or normal MORB (THI=1.6; Fe (super 3+) /Sigma Fe=0.16+ or -0.01). Our results show a correlation between THI and Fe (super 3+) /Sigma Fe ratios at these volcanoes, such that more tholeiitic magmas contain a greater proportion of reduced Fe, and more calc-alkaline magmas a greater proportion of oxidized Fe. At the same time, the maximum dissolved H (sub 2) O contents of basaltic melt inclusions from these volcanoes also broadly correlate with THI [1], and with measured Fe (super 3+) /Sigma Fe ratios, which is consistent with prior work [2], although H (sub 2) O is not the direct cause of oxidation. These findings suggest that H (sub 2) O and fO (sub 2) may both play key roles in the development of calc-alkaline affinity in arc magmas, but their respective functions in this process may be difficult to separate in natural systems because the subducted slab delivers fluids that generate arc magmas with both elevated H (sub 2) O and fO (sub 2) .

Initially, the Army expected the Apache to be a less technologically ambitious and cheaper alternative to the Cheyenne, in part to reduce the likelihood of another programmatic failure and also to accommodate the impending cancelation of the original armed escort and fire-suppression requirement (known as air assault) as doctrinal planning began to shift from counterinsurgency warfare in Vietnam to mechanized combat against concentrated Soviet armor in central Europe. Because the military departments executed the policies established by the Office of the Secretary of Defense, the Army controlled the extent to which OSD-initiated acquisition reforms structured weapons programs. As the Apache program evolved, costs escalated and schedules slipped because of required design modifications and the Army's decision to add more advanced weapons and avionics systems to the helicopter airframe. Congressional hostility to the Apache's rising cost, however, forced the Army leadership to restructure the program and reduce the total number of helicopters requested.

Anopheles oswaldoi s.l. has been incriminated as a malaria vector in Colombia and some localities in Brazil, but not ubiquitously throughout its Neotropical range. This evidence together with variable morphological characters and genetic differences supports that An. oswaldoi s.l. compromises a species complex. The recent fully integrated redescription of An. oswaldoi s.s. provides a solid taxonomic foundation from which to molecularly determine other members of the complex. Methods: DNA sequences of the Second Internal Transcribed Spacer (ITS2 - rDNA) (n = 192) and the barcoding region of the Cytochrome Oxidase I gene (COI - mtDNA) (n = 110) were generated from 255 specimens of An. oswaldoi s.l. from 33 localities: Brazil (8 localities, including the lectotype series of An. oswaldoi), Ecuador (4), Colombia (17), Trinidad and Tobago (1), and Peru (3). COI sequences were analyzed employing the Kimura-two-parameter model (K2P), Bayesian analysis (MrBayes), Mixed Yule-Coalescent model (MYC, for delimitation of clusters) and TCS genealogies. Results: Separate and combined analysis of the COI and ITS2 data sets unequivocally supported four separate species: two previously determined (An. oswaldoi s.s. and An. oswaldoi B) and two newly designated species in the Oswaldoi Complex (An. oswaldoi A and An. sp. nr. konderi). The COI intra- and inter-specific genetic distances for the four taxa were non-overlapping, averaging 0.012 (0.007 to 0.020) and 0.052 (0.038 to 0.064), respectively. The concurring four clusters delineated by MrBayes and MYC, and four independent TCS networks, strongly confirmed their separate species status. In addition, An. konderi of Sallum should be regarded as unique with respect to the above. Despite initially being included as an outgroup taxon, this species falls well within the examined taxa, suggesting a combined analysis of these taxa would be most appropriate. Conclusions: Through novel data and retrospective comparison of available COI and ITS2 DNA sequences, evidence is shown to support the separate species status of An. oswaldoi s.s., An. oswaldoi A and An. oswaldoi B, and at least two species in the closely related An. konderi complex (An. sp. nr. konderi, An. konderi of Sallum). Although An. oswaldoi s.s. has never been implicated in malaria transmission, An. oswaldoi B is a confirmed vector and the new species An. oswaldoi A and An. sp. nr. konderi are circumstantially implicated, most likely acting as secondary vectors.

We use XANES spectroscopy to provide Fe (super 3+) /Sigma Fe ratios of submarine mantle-derived basalts from mid-ocean ridges (MORB) as a proxy for fO (sub 2) . Fe (super 3+) /Sigma Feratios of MORB, far from plumes, decrease with indices of mantle enrichment such as (super 87/86) Sr and (super 208/204) Pb (n=22). In primitive glasses (MgO>8.5 wt.%, n=19), Fe (super 3+) /Sigma Feratios decrease strongly with increasing trace element enrichment, such as the Ba/La ratio. The strong inverse relationship between upper mantle fO (sub 2) and enrichment recorded by MORB glasses globally contrasts with the positive relationship hinted at by abyssal peridotite oxybarometry, and with the prediction of a positive correlation born of the expectation that Fe (super 3+) can be treated as more incompatible than Fe (super 2+) during mantle melting. These data unequivocally link upper mantle oxidation state to mantle source enrichment. Further, because the data require ancient fractionation of radiogenic parent-daughter pairs, the factors that lead to variation in mantle oxidation state must be preserved on plate tectonic time scales. Reduced lavas share isotopic and trace element signatures with low-degree carbonatitic and/or kimberlitic melts of peridotite. These include EM-1 isotopic flavor, Hf depletion relative to Nd, and strong enrichment of highly incompatible elements. Because upper mantle carbon may act to simultaneously reduce iron and generate melts that share geochemical traits with our reduced samples, we propose that variations in mantle carbon lead to magmas that are reduced and enriched. Estimates of mantle carbon concentration from Siqueiros and 'popping rock' support this interpretation, though other processes that might link enrichment to reduction, such as ancient subduction of reducing sediments or mobilization of reduced fluids at depth, cannot be ruled out.

The dataset contains 334 genera and 2769 species, yielding 1231 records of genera with 2274 occurrences worldwide. There is a bias towards eastern Laurentia, Baltica and Perunica records. Some 53.1% of the records are Ordovician. The study demonstrates that these molluscs are well suited to being used to improve understanding of Ordovician and Silurian biogeographical provinciality. Specific points are that: a Lower Ordovician assemblage is evident in Laurentia; the fauna of the Argentinean Precordillera is Laurentian until the Darriwilian, when taxa are shared with North China; Late Silurian gastropods from the Alexander terrane (SE Alaska) are unknown in Laurentia, but support a rift origin of this terrane from NE Siberia; Perunica, Ibero-Armorica and Morocco cluster together throughout the Ordovician but Perunica and Morocco are closer; Darriwilian-Sandbian deep-water Bohemian taxa occur in Baltica; a Laurentian-Baltica proximity is unsupported until the Silurian; Siberia clusters with North China and eastern Laurentia during the Tremadocian-Darriwilian; during the Gorstian-Pridoli Siberia clusters with the Farewell and Alexander terranes; North China may have been close to Laurentia and the Argentinean margin of Gondwana; and the affinity of Tarim taxa is problematic.

The Fe (super 3+) /Sigma Fe ratio proxy indicates that the mantle wedge has higher fO (sub 2) than mid-ocean ridge source mantle. In contrast, trace element proxies (V/Sc, Zn/Fe*, and [Cu]) suggest that the fO (sub 2) of the upper mantle is uniform. Additionally, the D (sub V) (super ol/melt) proxy suggests that arc magmas are oxidized at the time of high-Mg olivine fractionation. We present major and trace element concentrations and Fe (super 3+) /Sigma Fe ratios (mu -XANES) for melt inclusions and their olivine hosts from five Mariana arc volcanoes and Mariana Trough submarine glasses to compare the [Cu], Zn/Fe*, D (sub V) (super ol/melt) , V/Sc, and Fe (super 3+) /Sigma Fe ratio proxies for calculating fO (sub 2) . The Zn/Fe* proxy returns Fe (super 3+) /Sigma Fe ratios of primary mantle melts and is sensitive to variations in Zn/Fe* (sub source) . After accounting for source composition, the Zn/Fe* proxy yields agreement with calculated primary Fe (super 3+) /Sigma Fe ratios for arc and back-arc glasses. Similarly, the [Cu] of arc melt inclusions are consistent with non-modal equilibrium melting of a source between QFM+1 and QFM+2, and fractional melting between QFM and QFM +0.5 for back-arc magmas. The V/Sc proxy returns more reduced primary fO (sub 2) s than the Fe-based proxy for all samples, however fO (sub 2) s for arc melt inclusions calculated using D (sub V) (super ol/melt) (QFM+2.7 + or -0.3) are systematically more oxidized than their measured Fe (super 3+) /Sigma Fe ratios indicate (QFM+1.3 + or -0.3), suggesting that there may be a significant water, pressure, or source composition effect on the partitioning behaviour of V and Sc. These results show that the Fe-, Zn/Fe*-, and [Cu]-based proxies for fO (sub 2) are in broad agreement and are consistent with an arc mantle source that is more oxidized than mid-ocean ridge source mantle.

The fungal cultivars of "lower" attine ants are facultative symbionts, capable of living apart from ants, whereas the fungal cultivars of "higher" attine ants, including leaf-cutting genera Atta and Acromyrmex, are highly specialized, obligate symbionts. Since higher attine ants and fungi are derived from lower attine ants and fungi, understanding the evolutionary transition from lower to higher attine agriculture requires understanding the historical sequence of change in both ants and fungi. The biology of the poorly known ant genus Mycetagroicus is of special interest in this regard because it occupies a phylogenetic position intermediate between lower and higher ant agriculture. Here, based on the excavations of four nests in Para, Brazil, we report the first biological data for the recently described species Mycetagroicus inflatus, including the first descriptions of Mycetagroicus males and larvae. Like M. cerradensis, the only other species in the genus for which nesting biology is known, the garden chambers of M. inflatus are unusually deep and the garden is most likely relocated vertically in rainy and dry seasons. Due to the proximity of nests to the Araguaia River, it is likely that even the uppermost chambers and nest entrances of M. inflatus are submerged during the rainy season. Most remarkably, all three examined colonies of M. inflatus cultivate the same fungal species as their congener, M. cerradensis, over 1,000 km away, raising the possibility of long-term symbiont fidelity spanning speciation events within the genus.

That editorial was critiqued by de Bruyn et al. (2013, Journal of Biogeography, doi: 10.1111/jbi.12166) to whom we reply briefly here. Despite our shared goals - to understand what lives where and why - we argue from different philosophical premises. Although we may have little common ground, such debate encourages the good health of the field of biogeography.

There seems to be a deeply religious quality to advocacy for the investment in and support for human space exploration, lending to the endeavor of a "higher purpose" that helps to explain both the generous nature of the actual investment and the ultimate unwillingness of Americans to eviscerate space budgets despite less than full support for space exploration. This article examines religious conceptions as a means of analyzing what might be termed a "space gospel." I lay out here the proposition that human spaceflight may be viewed as a religion with similar attributes to those present in mainstream religious denominations. This approach to exploring the history of human spaceflight offers a different and useful frame of understanding that broadens basic conceptions about this aspect of the human past.

To explore how environmental variability relates to the expression of social behaviour, we collected 120 nests of the facultatively social sweat bee, Megalopta genalis (Halictidae: Augochlorini), along a nearly twofold rainfall gradient in central Panama. Brood rearing activity of bees in seasonal neotropical forests should track flowering phenologies, which are typically set by rainfall and phylogenetic patterns. Nests were collected at roughly similar times of year from three sites comprising wet, moist and dry lowland tropical forests. There were significant differences in ovarian development, brood production and body size across sites for some comparisons, but no effect on the proportion of social colonies collected at each site.

In zoology, studies of this kind have largely been restricted to Bilateria. Hexactinellids (glass sponges) readily lend themselves to test such an approach for early-branching (non-bilaterian) animals: they have a long and rich fossil record, but for certain taxa paleontological evidence is still scarce or ambiguous. Furthermore, there is a lack of consensus for taxonomic interpretations, and discrepancies exist between neontological and paleontological classification systems. Using conservative fossil calibration constraints and the largest molecular phylogenetic data set assembled for this group, we infer divergence times of crown-group Hexactinellida in a Bayesian relaxed molecular clock framework. With some notable exceptions, our results are largely congruent with interpretations of the hexactinellid fossil record, but also indicate long periods of undocumented evolution for several groups. This study illustrates the potential of an integrated molecular/paleobiological approach to reconstructing the evolution of challenging groups of organisms.

Quantification of invasions is necessary for understanding impacts and identifying remnant earthworm-free areas, but existing sampling techniques are effort-intensive and/or environmentally damaging. We: (1) developed and applied a protocol that allows rapid classification of earthworm invasion into five stages based primarily on visual assessment of the forest floor, (2) sampled earthworms to test whether the protocol's stages can predict invasion by different species, and (3) assessed relationships between individual forest floor characteristics and presence of different earthworm species. Based on differences in biomass among points assigned to different stages, the 5-stage classification protocol accurately identified the onset of invasion by Lumbricus rubellus and Lumbricus terrestris, the species of greatest management concern in the northern Midwest. Except for middens as a predictor of L. terrestris presence, no forest floor variable was useful by itself for assessing invasions. The 5-stage protocol provides an efficient approach for assessing earthworm invasions in hardwood forests of the U.S. northern Midwest, can be implemented with minimal training, and serves as a blueprint for similar protocols in other regions experiencing earthworm invasions.

At this ecotone, Avicennia germinans (black mangrove) seedlings grow in competition with salt marsh species and provide a natural experiment. The seedlings were subjected to nutrient enrichment and released from aboveground competition via a meshing treatment. Aboveground competition removal decreased leaf area and foliar C:N (by 44.1% and 26.8%, respectively) while N-enrichment increased mangrove leaf production by 41.7%, foliar N by 62.2%, and leaf biomass by 72.1%. These results indicate that A. germinans seedlings significantly modify leaf characteristics in response to changing availability of light and nutrient resources. This work illustrates that mangrove seedlings (1) show large plasticity in both growth and nutrient acquisition, and (2) compete with salt marsh species. Our work also brings to light the interactive effects of biotic and abiotic drivers of mangrove productivity and the need for more multifactorial work in this important ecotone, where range shifts may be occurring.

However, this approach is often limited by the challenges of accurately characterizing social structure and measuring network heterogeneity. Technological advances have facilitated the study of social networks, but to date, all such work has focused on large vertebrates. Here, we provide proof of concept for using proximity data-logging to quantify the frequency of social interactions, construct weighted networks and characterize variation in the social behaviour of a lek-breeding bird, the wire-tailed manakin, Pipra filicauda. Our results highlight how this approach can ameliorate the challenges of social network data collection and analysis by concurrently improving data quality and quantity.

This record is unique because both arc and continental margin are now severely fragmented and only partially exposed along the southern Caribbean-South American boundary in northern Colombia. We studied these clastic sequences in the San Jacinto deformed belt using an integrated provenance study that includes conglomerate clast counting, geochemistry and U-Pb and Hf isotopic analysis in magmatic clasts, together with sandstone petrography, heavy mineral analysis and detrital zircon U-Pb geochronology. The record of events extracted from these coarse clastic rocks includes the formation and approach of an allochthonous Upper Cretaceous intra-oceanic arc active from 88Ma until 73Ma. This arc collides against the upper Paleozoic to Triassic continental margin after 73Ma, but before late Paleocene times. Poorly exposed remnants of serpentinized peridotites and middle pressure metamorphic detritus are related to closure of an intervening oceanic basin between the continent and the colliding arc. This orogen was emerged in late Maastrichtian-early Paleocene, and then collapsed as recorded by the thick upper Paleocene and younger succession of the San Jacinto deformed belt where the coarse clastics, subject of this study, are exposed.

Thicknesses of 3183 oxidized layers in 85 long cores (10 to 45 m) are examined to determine the nature of down-section and spatial patterns. The thickest layers are at depths of 1 to 2 m (dating to <1000 y BP) and become significantly reduced within the next meter due to (1) rapid expulsion of interstitial pore water from overburden compression of sediment and (2) evaporation in near-surface deposits in this hyperarid setting. Thicknesses decrease more irregularly to depths of 5 to 6 m and then more gently to the base of the sections. The more gradual compaction of strata at mid- and lower-core depths accounts for more than 50% of total Holocene compaction. The derivatives of regression curves determine the strata thickness reduction rate, which is treated as a proxy for compaction rate. Average compaction rates for Holocene sections vary along the approximately 225-km-long coastal margin: about 8.4 mm/y in the NE, about 7.7 mm/y in the NC, and about 3.7 mm/y in the NW sectors. These rates, somewhat higher than those previously proposed for this delta, are within the range for land subsidence obtained from recent satellite surveys. The interaction of natural factors, such as moderate to high compaction rates and rising global sea level, with human activities, especially those reducing sediment supplied to the lower delta, presents serious concerns for the delta's future. Without emplacement of a continuous network of protective structures along the coast, a marked landward retreat of about 30 km by the Mediterranean coast is projected in little more than a century, resulting in submergence and loss of agricultural and wetland terrains vital to Egypt's rapidly expanding population.

2012-022782 AB - There is growing evidence that changes in deep-sea benthic ecosystems are modulated by climate changes, but most evidence to date comes from the North Atlantic Ocean. Here we analyze new ostracod and published foraminiferal records for the last 250,000 years on Shatsky Rise in the North Pacific Ocean. Using linear models, we evaluate statistically the ability of environmental drivers (temperature, productivity, and seasonality of productivity) to predict changes in faunal diversity, abundance, and composition. These microfossil data show glacial-interglacial shifts in overall abundances and species diversities that are low during glacial intervals and high during interglacials. These patterns replicate those previously documented in the North Atlantic Ocean, suggesting that the climatic forcing of the deep-sea ecosystem is widespread, and possibly global in nature. However, these results also reveal differences with prior studies that probably reflect the isolated nature of Shatsky Rise as a remote oceanic plateau. Ostracod assemblages on Shatsky Rise are highly endemic but of low diversity, consistent with the limited dispersal potential of these animals. Benthic foraminifera, by contrast, have much greater dispersal ability and their assemblages at Shatsky Rise show diversities typical for deep-sea faunas in other regions. Statistical analyses also reveal ostracod-foraminiferal differences in relationships between environmental drivers and biotic change. Rarefied diversity is best explained as a hump-shaped function of surface productivity in ostracods, but as having a weak and positive relationship with temperature in foraminifera. Abundance shows a positive relationship with both productivity and seasonality of productivity in foraminifera, and a hump-shaped relationship with productivity in ostracods. Finally, species composition in ostracods is influenced by both temperature and productivity, but only a temperature effect is evident in foraminifera. Though complex in detail, the global-scale link between deep-sea ecosystems and Quaternary climate changes underscores the importance of the interaction between the physical and biological components of paleoceanographical research for better understanding the history of the biosphere.

For example, oxidation state will affect core size, as well as Mg# and pyroxene content of the silicate mantle. The Howardite-Eucrite-Diogenite class of meteorites (HED) provide an interesting test-case of this idea, in particular in light of results of the Dawn mission which provide information on the size, density and differentiation state of Vesta, the parent body of the HED's. In this work we explore plausible bulk compositions of Vesta and use mass-balance and geochemical modelling to predict possible internal structures and crust/mantle compositions and mineralogies. Models are constrained to be consistent with known HED samples, but the approach has the potential to extend predictions to thermodynamically plausible rock types that are not necessarily present in the HED collection. Nine chondritic bulk compositions are considered (CI, CV, CO, CM, H, L, LL, EH, EL). For each, relative proportions and densities of the core, mantle, and crust are quantified. Considering that the basaltic crust has the composition of the primitive eucrite Juvinas and assuming that this crust is in thermodynamic equilibrium with the residual mantle, it is possible to calculate how much iron is in metallic form (in the core) and how much in oxidized form (in the mantle and crust) for a given bulk composition. Of the nine bulk compositions tested, solutions corresponding to CI and LL groups predicted a negative metal fraction and were not considered further. Solutions for enstatite chondrites imply significant oxidation relative to the starting materials and these solutions too are considered unlikely. For the remaining bulk compositions, the relative proportion of crust to bulk silicate is typically in the range 15 to 20% corresponding to crustal thicknesses of 15 to 20 km for a porosity-free Vesta-sized body. The mantle is predicted to be largely dominated by olivine (>85%) for carbonaceous chondrites, but to be a roughly equal mixture of olivine and pyroxene for ordinary chondrite precursors. All bulk compositions have a significant core, but the relative proportions of metal and sulphide can be widely different. Using these data, total core size (metal+ sulphide) and average core densities can be calculated, providing a useful reference frame within which to consider geophysical/gravity data of the Dawn mission. Further to these mass-balance calculations, the MELTS thermodynamic calculator has been used to assess to what extent chondritic bulk compositions can produce Juvinas-like liquids at relevant degrees of partial melting/crystallization. This work implies that alkali contents play a key role on the major element chemistry of basaltic liquids, and that basaltic eucrites were produced from melting and/or crystallization of an alkali-poor source. Overall, these results provide a useful and self-consistent reference frame for interpretation of the data from the VIR and GRaND instruments onboard the Dawn spacecraft.

MG/NL trend eucrites are characterized by a negative correlation between the Mg/Fe ratio and incompatible element abundances. Conversely, the ST trend eucrites are characterized by small variation in Mg/Fe ratio and enrichment in incompatiable elements [2]. The most widely accepted models to explain the genesis of the two trends argue the MG/NL trend is the result of fractional crystallization from a magma ocean, while the ST trend is the result of partial melting of the eucritic parent body crust [3], or alternatively the MG/NL and ST trends could have formed from different degrees of partial melting of the parent body's ultramafic mantle [4]. However, both models fail to completely explain the chemical relationships among the eucrites. Yamaguchi et al. [2] defined a new subset of eucrites (residua eucrites), which could be genetically related to ST trend eucrites. In this model, the ST trend eucrites are enriched in incompatible elements by crustal partial melting, which depleted the residua eucrites [5]. We propose a melt-rock reaction model for the genesis of ST trend eucrites and residua eucrites, which is an extension of the partial melt model described above. Melt-rock reactions can cause drastic changes in the trace element abundances of a rock, while only causing subtle changes in the major element composition. For example during melt-rock reaction in the terrestrial mantle clinopyroxene is dissolved while orthopyroxene is crystallized, which severely depletes the residua in incompatible trace elements [6]. A melt-rock reaction in eucritic basalts would cause the incompatible-rich mesostasis phases, e.g., phosphates, ilmenite, to partition into the melt and plagioclase to crystallize [5]. As <1 wt% P (sub 2) O (sub 5) is soluble in a eucritic melt (calculated from [7]), if enough phosphates react with the melt, an accumulation of phosphates should be found at the melt-rock reaction interface, similar to orthopyroxene accumulations in the terrestrial mantle [6]. Indeed, the residua eucrite EET 90020 contains areas with apatite/plagioclase enrichment [8] with calculated P (sub 2) O (sub 5) concentrations of approximately 3-10 wt%. The accumulation of apatite and plagioclase along with the annealed texture encompassing the apatite/plagioclase implies that melt-rock reaction took place in the residua eucrite EET 90200. Preliminary REE-modeling of the residua suggests that the reacted melt resembles the ST trend. Thus, we suggest a melt-rock reaction process for the genesis of Stannern trend eucrites, residua eucrites, and the apatite-rich accumulation in EET90020. Also, apatite-rich accumulations are expected to be found in other residua eucrites. Finally, because apatite crystallized instead of merrillite, eucritic melts must have contained significant water.

What have we learned at Vesta? And, what do we expect to learn by comparing Vesta and Ceres? We will address these questions from the standpoint of geochemistry. Dawn's Gamma Ray and Neutron Detector (GRaND) is sensitive to the elemental composition of surface materials to depths of a few decimeters [1]. Gamma rays and neutrons, produced by the steady bombardment of galactic cosmic rays and by the decay of naturally-occurring radioisotopes (K, Th, U), provide a chemical fingerprint of the regolith. Analysis of planetary radiation emissions enables mapping of specific elements (such as Fe, Mg, Si, Cl, and H) and compositional parameters (such as average atomic mass), which provide information about processes that shaped the planet's surface and interior. Dawn has exceeded operational goals for GRaND at Vesta, accumulating an abundance of nadir-pointed data during five months in a 210 km, low altitude mapping orbit around Vesta (265-km mean radius). Chemical information from gamma ray and neutron measurements was used to test the connection between Vesta and the howardite, eucrite, and diogenite (HED) meteorites [2]. Additionally, GRaND searched for evolved, igneous lithologies [3], mantle and upper crustal materials exposed in large impact basins, mesosiderite compositions, and hydrogen in Vesta's bulk regolith. Results of our analyses and their implications for thermal evolution and regolith-processes will be presented. The possibility of a subcrustal ocean [4, 5] and lack of cerean meteorites makes water-rich Ceres a compelling target of exploration [6]. If Ceres underwent aqueous differentiation, then crustal overturn or gas driven volcanism may have significantly modified its primitive surface; and products of aqueous alteration (e.g. [7]) would detectable by GRaND [1]. For example, the presence of Cl in salts, associated with liquid-water-processes, would have a profound effect on the thermal neutron leakage flux. GRaND is sensitive to H and H-layering, which may be in the form of endogenic water ice or hydrous minerals on Ceres. Ammonia ice (e.g., from recent cryovolcanism) would produce a distinctly different neutron signature than water ice [1]. Prospective results for GRaND at Ceres will be presented in the context of what we have learned about Vesta. 1. Prettyman, T.H., et al., Dawn's Gamma Ray and Neutron Detector.

However, most of these surfaces show limited enhancements in both derived rock abundance and rock-free regolith temperatures calculated from Diviner nighttime infrared observations. This indicates that the surface rocks are covered by a layer of thermally insulating regolith material. By matching the results of one-dimensional thermal models to Diviner nighttime temperatures, we have constrained the thermophysical properties of the upper regolith, and the thickness of regolith overlying proximal ejecta. We find that for all of the regions surveyed (all in the nearside highlands), the nighttime cooling curves are best fit by a density profile that varies exponentially with depth, consistent with a linear mixture of rocks and regolith fines, with increasing rock content with depth. Our results show significant spatial variations in the density e-folding depth, H, among young crater ejecta regions, indicating differences in the thickness of accumulated regolith. However, away from young craters, the average regional "equilibrium" value of H (Heq) is remarkably consistent, and is on the order of 5 cm. As expected, near-rim ejecta associated with young craters show lower values of H, indicating a high rock content in the shallow subsurface; for older craters, the average value of H approaches the regional value of Heq. Calculated H values for young craters (Giordano Bruno, Moore F, Byrgius A, Necho, Tycho, Jackson, King, and Copernicus) show a clear correlation with published ages, providing the first observational constraint on the recent rate of lunar regolith accumulation. In addition, this result may help to resolve the apparent discrepancy between ages calculated from small crater counts on melt ponds versus counts on continuous ejecta (e.g., King crater; Ashley et al., 2011, LPSC 42, abstract 2437). This method could, in principle, be extended to other airless bodies (e.g., asteroids), which would in turn constrain the recent impactor flux.

For bodies with both orbital missions and samples available for laboratory study, missions provide global chemical, mineralogical, and geologic data sets and context for samples, whereas samples often provide complementary petrogenetic histories in a chronological framework. In contrast, although the wealth of orbital data from MESSENGER is not complemented by samples from Mercury, petrologic and experimental studies remain essential to understanding the innermost planet. Prior to MESSENGER, most models centered on high-temperature events and formation under highly reducing conditions to explain Mercury's high metal to silicate ratio. These models predicted enrichment in refractory elements and depletion in volatile elements. The inference of formation at highly reducing conditions is supported by MESSENGER results. The low FeO concentration in the crust, implied low FeO contents of the mantle, apparent efficient partitioning of iron into the core, and evidence for Ca- and/or Mg-sulfides from X-Ray Spectrometer data are all consistent with reducing conditions. In contrast, the suggestion that Mercury is highly volatile-depleted has been refuted. Direct evidence for a relatively volatile-rich planet come from Na, K, and S abundances measured on the surface with MESSENGER's XRS and Gamma-Ray Spectrometer and the presence of neutral and ionized Na, K, and S species in the exosphere. Indirect evidence for volatile-rich compositions include the suggestion of volcanic vents with associated mantling pyroclastic deposits, hollows inferred to form by geologically recent volatile loss, and an inferred interior structure that includes a solid iron sulfide layer at the top of Mercury's fluid core. Petrologic and experimental studies of meteorites have played a key role in deciphering orbital data from MESSENGER. Partial melts from an enstatite chondrite assemblage produce S-rich silicate melts that subsequently crystallize Ca,Mg-sulfides and an Fe,Ni-FeS melt rich in Si, consistent with the geochemical characteristics observed or inferred from Mercury. The application of these petrologic principles, derived from the study of highly reduced meteorites, has advanced our understanding of Mercury. With new insights into the geology, mineralogy, and geochemistry of Mercury, the possibility exists that a meteorite launched from Mercury by an impact event could be identified on Earth. If such a link can be forged between a meteorite and Mercury, a new era of exploration, one largely based on isotopic systematics to understand the nature and timing of the geologic evolution of Mercury, could begin.

The reported Fe/Si ratios ( approximately 0.03 to 0.15) gave an upper limit of approximately 4 wt% Fe. This limit is consistent with the bulk estimate provided by the Gamma-Ray Spectrometer (Fe/Si: approximately 0.12) and the upper limit of approximately 6 wt % FeO in silicate minerals that is constrained by reflectance spectroscopy. Reliable Fe abundance estimates are difficult to obtain from XRS data for several reasons, including: (i) strong solar flares are required to excite Fe X-ray fluorescence, and such flares occur rarely; and (ii) energetic particle events often accompany the strongest solar flares, causing fluorescence of the instrument's Cu collimators and spectral contamination close to the Fe K lines at 6.4-7 keV. Forward modeling of XRS data from more than 30 flares during the first year of MESSENGER's orbit reveal that Fe is ubiquitously lower on Mercury (Fe/Si ranging from 0.02 to 0.18, with a peak in the distribution at approximately 0.06, or approximately 1.5 wt% Fe) than on other terrestrial planets. Although the abundance of Mg across the surface of Mercury is known to vary according to geological terrain, our data indicate that this variation is not a result of Fe substitution for Mg in mafic silicates. A correlation between Ca and S (and to a lesser extent between Mg and S) has previously been reported from the XRS data. Mercury's high S contents likely reflect the presence of abundant sulfide minerals, such as oldhamite (Ca,Mg,Fe)S. Our data reveal further correlations between Fe and Ca, and between Fe and Mg, suggesting that sulfides (most likely troilite, FeS, and/or oldhamite) are a major carrier of Fe on Mercury's surface. The low Fe content of Mercury's surface supports the very low FeO contents that are predicted from both melting experiments on enstatite chondrites and from thermodynamic modeling. However, even the few wt% Fe on Mercury are higher than in the experimental work. The incorporation of an FeS immiscible melt into the crystallizing magma may account for this discrepancy and explain the abundance of Fe on Mercury's surface. Analysis of a larger dataset including results from solar flares during MESSENGER's extended mission will give a more robust estimate of the range of Mercury's surface Fe content, and thus help determine the planet's bulk composition and interior structure. This information will also constrain more tightly the oxygen fugacity of Mercury's interior and thus contribute to our steadily increasing understanding of the innermost planet's formation and evolution.

Our goal is to achieve a better understanding of the nature and timing of the layered deposits and their relationship to climatological cycles by enabling the mapping of subsurface radar returns in regions presently obfuscated by highly variable surface topography and complex subsurface structures. In the medical field, computed axial tomography (CAT scan) involves taking a series of 2-D X-ray images around an axis of rotation and applying geometric processing to generate a 3-D image of a body's interior. Similarly, SHARAD has taken over 2500 2-D radar images (radargrams) on passes of the Mars Reconnaissance Orbiter (MRO) across the north polar region of Mars, and we have used a subset of those radargrams to develop a means of generating 3-D images of the polar layered deposits. While the sets of radargrams over both polar regions have been very fruitful scientifically (e.g., Putzig et al., 2009, Icarus 204, 443-457; Holt et al., 2010, Nature 465, 450-453; Phillips et al., 2011, Science 332, 838-841), examination of 3-D subsurface structures has been restricted to identifying and tracing those structures on the radargrams and then "connecting the dots" by interpolation. Identification and tracing of structures is limited to the trajectories of MRO's nadir track and is hampered by "clutter," or signals returned from off-nadir surface or subsurface features that often interfere with signals returned from nadir. Clutter becomes a severe impediment to structure interpretation in areas of high topographic variability, such as the trough-rich regions of Planum Boreum. Given a sufficient number of observations from a range of lateral offsets, radar signals from nadir and off-nadir can be distinguished within a 3-D volume, and off-nadir clutter can be repositioned and promoted to signal in its source location. Such 3-D imaging techniques are well developed not only in the medical field but also in terrestrial subsurface radar and seismic studies, where they are commonly referred to as "migration." Available 3-D imaging software requires that the data first be binned into a 3-D grid and co-registered to a common datum. For SHARAD, the Martian ionosphere introduces a complication in that it significantly distorts and delays the radar signals on the sunlit side of the planet. To address phase distortion, we apply an autofocus technique (Campbell et al., 2011, IEEE Geosci. Remote Sens. Lett. 8, No. 5) that relies on an empirically derived phase correction of the SHARAD signal and optimization of an image-quality metric over 100-km segments of each affected radargram. This method also allows us to estimate the along-track variable delays introduced by the ionosphere. We remove any residual delays using a correlation technique applied to the data subsequent to the 3-D binning step. At that point, we proceed to migration of the data, yielding a geometrically corrected 3-D volume of SHARAD data.

Results and interpretations presented here from impact ejecta (Barringer Meteorite Crater), volcanic deposits (Northern Arizona cinders overlying lavas, columnar-jointed Columbia River flood basalts, Hawaii lava flows), and terrains influenced by fluvial-related activity (channeled scablands megaflood bar, Mauna Kea glacio-fluvial deposits) focus on defining the radar "fingerprint" of geologic materials and settings that may be analogous to those found on the Moon and Mars. The challenge in using GPR in geologic investigations is the degree to which different geologic features and processes can be uniquely identified and distinguished in the data. Our approach to constraining this is to qualitatively and quantitatively characterize GPR signatures of different geological environments and to compare them with "ground-truth" observations of subsurface exposures immediately adjacent or subjacent to our GPR transects. Several sites were chosen in each field area based on accessibility, visual access to the subsurface, and presence of particular geologic features of interest. The interpreted distribution of blocks in impact ejecta at Meteor Crater, using a 400 MHz antenna (wavelength of 75 cm) is 1.5-3 blocks per m (super 3) in the upper 1 m (and 0.5-1 blocks per m (super 3) in the upper two meters), which is close to the in situ measured block distribution of 2-3 blocks larger than 0.25-0.30 m per m (super 3) . This is roughly the detection limit to be expected from the lambda /3 resolution approximation of radar wavelength and indicates that the 400 MHz GPR is characterizing the block population in ejecta. While megaflood bar deposits are also reflector-rich, individual reflectors are in general more easily distinguished. At multiple sites, cinders appear smoothly, regularly layered, and allow for excellent GPR penetration. Consequently, the often rough relief of underlying lava flows is discernable, allowing thickness and volume estimates to be made, as well as giving some idea of structure within/on the buried flow. Alternations of massive and clinkery horizons within a'a' flows are detected, as are features representing the interface of overlapping pahoehoe flows (likely due to relatively high relief and fracturing associated with squeeze-ups, etc). Accumulations of gravel, pebbles, and fines derived from lavas and cinders and emplaced by alluvial and mass-wasting processes (along the margins of Apollo Valley, Mauna Kea) appear similar to the pure cinders, as it is likely the same porosity and grain-size characteristics that cause layered GPR reflections. In any case, such layers allow interpretation of how successive events filled in surface relief of the underlying (lava) substrate. GPR data of the interior fill of western Apollo Valley reveals relatively flat reflectors in the along-valley direction and inter-fingering, pinching-out, and dome- and trough-shaped reflectors in the cross-valley direction, indicating accumulation by multiple overlapping lobes coming down the valley, possibly due to multiple fluvial events over time.

AN - 1660632041; 2015-018370 AB - Both laser altimetric and stereo photogrammetric datasets returned by the MESSENGER spacecraft in orbit about Mercury reveal impact craters whose floors show systematic tilts away from topographically high regions. Such tilted craters indicate that Mercury's lithosphere has been affected by large-scale folding that, when mapped, is manifest as several long-wavelength and low-amplitude rises and troughs, interpreted as anticlines and synclines, that cross the planet. Topographic profiles across the syn- and anticlines show that folding can be described as more or less harmonic with wavelengths of 800 to 1300 km and amplitudes of 1.5 to 3 km. These dimensions show that folding accommodated shortening strains of only approximately 0.002%. Several syn- and anticlines are found in the region in and around the Caloris basin, the largest recognized impact basin on the planet. The topography within the basin is characterized by two anticlines, each trending approximately east-west and having crests that rise more than 2 km above a low-lying region near the basin center. Fault displacement analysis of several radial graben and circumferential ridges, together with crater excavation depths of spectrally distinct materials, yields stratigraphic information on the uppermost smooth volcanic plains in the basin's interior, revealing a pinch-and-swell structure to these units. Specifically, the plains are thicker in the vicinity of the topographic highs and thinner at the topographic low. We used numerical simulations with the two-dimensional module of the finite-element modeling code ADELI to explore how folding of the lithosphere on Mercury and the pinching and swelling might have been accommodated for a range of assumed boundary conditions and properties of the lithosphere and mantle, informed by recent geophysical data returned by MESSENGER. We find that continuing lithospheric folding with periodic emplacement of volcanic plains units can account for the observed topography and stratigraphy. In particular, we achieved best fits between our models and observations with a scenario involving lithospheric boudinage. Under this scenario, the emplacement of volcanic units on preexisting syn- and anticlines led to thickness variations across the plains, and further folding facilitated their pinching and swelling to ultimately produce an inversion of the original relative topography. This inversion is also evident in the order of mapped rises and troughs outside the basin, in that the proposed anticlines inside Caloris continue as synclines of greater amplitude along the same azimuthal trends outside the basin. These observations imply that lithospheric folding spanned an extended time interval that included the time of smooth plains emplacement. Loads induced by the smooth plains potentially influenced the folding, whereas strains of the folding are too low to have influenced the development of the complex faulting pattern in the basin. The concept of lithospheric boudinage in Caloris not only accounts for the observations of topography and stratigraphy, but also has implications for the rock mechanical behavior of Mercury's lithosphere and mantle in general.

Lobate scarps and high-relief ridges, compressional features that generally have approximately 1 km of relief and are hundreds of kilometers long, were identified on Mercury from images acquired during the Mariner 10 and MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) flybys. Images taken from orbit during the primary MESSENGER mission, with full coverage of the surface, confirmed that these scarps and ridges appear to be concentrated in three broad, north-south bands. Images at high incidence angles, collected since April 2012 during the MESSENGER extended mission, provide a more complete picture of the spatial extent and orientations of these features, and of their relationship to neighboring landforms. Digital elevation models, from laser altimetry and stereo imaging, additionally allow for comparisons between tectonic landforms and elevation and for measurements of slope and relief across individual features. Scarps and ridges are found at a wide range of elevations on Mercury. The greatest concentration of such features in an equatorial lowland setting is in an area (40 degrees N-40 degrees S, 220 degrees -270 degrees E) that is within one of the three north-south bands of tectonic features. Within this area, the 48 previously mapped features generally do not display preferred orientations or a consistent relationship to topography. Of these scarps, 47 were identified in flyby images and one in orbital images. Three follow the rim of Beethoven basin (10 degrees -30 degrees S, 225-245 degrees E, approximately 600 km diameter), likely having formed along earlier zones of weakness in the crust created during formation of the basin. From recent images taken at high incidence angles, which currently have approximately 75% coverage in this equatorial lowland area, we are able to identify only seven additional tectonic features, all within Beethoven basin. Six of these newly identified features are also subparallel to the basin rim. However, no other scarps in our study area are so clearly connected to a particular topographic or geologic feature. The 22 lobate scarps and high-relief ridges in the northeastern quadrant of our study area have similar base elevations (average of -0.78 km, standard deviation of 0.17 km) and relief. Maximum measured relief (along one scarp) averages 0.59 km (standard deviation of 0.13 km), with a median of 0.56 km. Additionally, the scarps often terminate at a neighboring scarp, in six cases such that the two scarps are tangent to each other, and in four cases such that they intersect at an angle of > or =45 degrees . These similarities and relationships suggest that the 22 features may be tectonically linked and may have therefore formed as an assemblage within a relatively short interval of time. This assemblage of faults is located in an area of apparently limited lateral variation in crustal thickness, as indicated by crustal models consistent with long-wavelength topography and gravity. If the limited range in crustal thickness in this area was paralleled by a limited range in mechanical lithosphere thickness, this may have facilitated the formation of an assemblage of linked tectonic features.

We systematically explored and discovered natural hydrocarbon seeps, diverse coral ecosystems, wooden and iron-hulled shipwrecks more than 100 years old colonized by coral communities, and sperm whale habitat between 600 and 1200m. A total of sixteen dives took advantage of new and recent maps to explore and groundtruth both hard and soft-bottom habitats, from Cretaceous carbonates to mounds of coral rubble. The final ROV dive successfully groundtruthed expected methane-release areas imaged by the ship's mapping systems up to 1150m above the seafloor. The source of the mapping imagery was a stream of bubbles issuing from beneath thriving seep mussel communities. We visited five sites in the Mississippi Canyon (MC) area (lease blocks MC294, MC297, MC388, MC255, and MC036; the DWH incident took place in MC252). These sites were 11.3 km SW, 6.8 km SW, 7.6 km SW, 25.7 km E, and 27.4 km to the NE of the DWH, respectively. We used high-definition imaging systems on the Little Hercules ROV and Seirios camera platform to document more than 130 coral colonies and over 400 associated individual animals to continue to assessing the impact of the Deepwater Horizon oil spill. All of these efforts were conducted to provide fundamental knowledge of unknown and poorly known regions, ecosystems, and items of historical significance in the deep Gulf of Mexico.

These presumably passive continental margin sites provide the means to establish a N-S spatial trend in the varying influences of GIA, eustatic components of Holocene sea level, extent of forebulge collapse and influence of rotational feedback over a 20 degrees latitudinal range. Previous ICE6G (VM5A) model-coral data comparisons for St Croix, USVI, Antigua, Martinique and Barbados (Toscano, Peltier and Drummond, 2011, QSR) along the eastern Caribbean Plate and island arc illustrated the close model-data compatibility, the influence of rotational feedback acting as a significant factor in reducing misfits, and the need for high quality in situ data to confirm the extension of the proglacial forebulge into tropical latitudes. The gradient of western Caribbean continental shelf sites comprises a much more varied range of model-data relationships based on extensive combined Acropora palmata (reef crest coral) and Rhizophora mangle (microtidal mangrove) peat datasets in all cases. Starting at the northernmost region with the Florida Keys, there exist negative model misfits to the data, suggesting the possibility of a positive tectonic overprint upon expectations related to the glacial isostatic adjustment process acting alone, even though this region is normally believed to be tectonically stable. The largest multi-proxy database from Belize supports the likelihood of increasing rates of subsidence from north to south in the Belize Lagoon, which may account for numerous positive GIA model-data misfits. The southernmost site at Panama is most similar to Belize in the possible nature of tectonic influences on data elevations. It is important to note that our suggestion of the possible importance of tectonic overprints upon Holocene sea level histories from parts of the Caribbean region are consistent with the results of Engelhart et al. (2011, Geology) who have established the existence of an increasing misfit of RSL observations to the predictions of the global model of the GIA process at sites in the Carolinas at ages in excess of approximately 4 ka. The currently available combined Acropora palmata and Rhizophora mangle peat dataset from the Florida Keys is of high quality, but whether it will require the misfit identified in the Carolinas to extend to this further south location will be tested. However, this region is characterized by sufficiently weak influence of the global GIA process of proglacial forebulge collapse that longer timescale processes associated with the mantle convective circulation and other tectonic processes may become evident. Although significant effort has been invested in analyzing the degree to which modifications to the mantle viscosity profile and glaciation history might lead to a reconciliation of the identified misfits at both Florida and Belize, such variations must be constrained by the need to maintain the fits to the data at other critical locations.

These dunes include the largest single-structured sand dune present in North America. Wind records from the Remote Automated Weather Station (RAWS) installation at the Mountain Home Air Force Base, which is approximately 21 km NW of the Bruneau Dunes, have proved to be very helpful in assessing the regional wind patterns at this section of the western Snake River Plains province; a bimodal wind regime is present, with seasonal changes of strong (sand-moving) winds blowing from either the northwest or the southeast. During April of 2011, we obtained ten precision topographic surveys across the southernmost reversing dune using a Differential Global Positioning System (DGPS). The DGPS data document the shape of the dune going from a low, broad sand ridge at the southern distal end of the dune to the symmetrically shaped 112-m-high central portion of the dune, where both flanks of the dune consist of active slopes near the angle of repose. These data will be useful in evaluating the reversing dune hypothesis proposed for enigmatic features on Mars called Transverse Aeolian Ridges (TARs), which could have formed either as large mega-ripples or small sand dunes. The symmetric profiles across TARs with heights greater than 1 m are more consistent with measured profiles of reversing sand dunes than with measured profiles of mega-ripples (whose surfaces are coated by large particles ranging from coarse sand to gravel, moved by saltation-induced creep). Using DGPS to monitor changes in the three-dimensional location of the crests of the reversing dunes at the Bruneau Dunes should provide a means for estimating the likely timescale for changes of TAR crests if the Martian features are indeed formed in the same manner as reversing sand dunes on Earth.

Deglaciation subjects lakes to interannual variability, raising questions about its impact on metabolic activity and biogeochemical cycles, lake habitat, ecosystem, and biodiversity. Documenting these questions contributes to a better understanding of the changes affecting Earth's glacial lake ecosystems, and may shed light on how life adapted during past deglaciations. From an astrobiological perspective, it brings new insights into the evolution of Mars habitability during comparable geological periods. Further, the robotic exploration of glacial lakes confronts us with challenges analogous to those that will be faced by future planetary missions to Titan's planetary seas. PLL, thus, bridges planets along an intertwined pathway where the study of one planet informs on the evolution of others and on the technological challenges associated with their exploration. During our field field campaign In November 2011, we characterized the physical, geological, and biological environment of Laguna Negra (33.65S -70.13W) a 6-km large, 300 m deep glacial lake, and generated an environmental database to baseline the adaptive system that will be used in the future by the lake lander to autonomously monitor the lake. Time series show changes in precipitation over the past decades, and in temperature and relative humidity. Meteorological stations and a stream gauge are tracking daily and seasonal changes at high resolution. Data are correlated to daily vertical profiles performed by the lake lander to monitor physico-chemical changes. Bathymetric maps reveal the bottom topography, and isolated habitats. Most dominant spectral units have been defined in ASTER near- and thermal infrared. They were sampled from spectra and hand specimens in the field and are now being characterized for mineralogic compositions in the lab. Three 24-hour time-lapse thermal videos show changing surface temperature conditions around the lake, which can be controlled by solar radiation, surface moisture content, grain size, slope, and/or geology. Changes in archea and bacteria populations are observed from 0-20 m. The archaeal community is represented by only one hand with similar electrophoresis mobility in the DGGE profile of most samples. Water column and sediment samples were collected and analyzed by sandwich microarray immunoassays, and by cloning and sequencing bacterial and archaeal 16SrRNA gene. Biomarker and microbial profiles were obtained by using a Life Detector Chip (LDChip450), which contains 450 antibodies raised against whole microbial cells (archea and bacteria), extracellular polymers, exopolysaccharides, universal biomarkers like DNA, amino acids, and other biomolecules. We prototyped and tested an underwater microscopic imager for long-term in situ study of copepod behavior that will use algorithms to automatically detect and track copepods in images.

Obsidian hydration rind dating has been used in archaeology as a tool to date artifacts, but this technique has not been applied to in situ collected lavas. Basalt glasses from Kilauea, Mauna Loa, and Hualalai volcanoes, Hawaii, were analyzed by FTIR spectroscopy to calculate the increase in total water content along diffusion profiles extending from sample interiors through their hydration rinds; rinds are typically <50 mu m thick. Batch processing of FTIR spectra provides initial results showing increases in water content by up to 50% (increasing from approximately 0.08 to approximately 0.12 wt.% total water) within approximately 5500 years in a dry climate. In a wet climate, however, hydration data are more scattered, most likely the result of devitrification and erosion of the glassy lava rinds. In an intermediate climate, total water content in the rinds as much as doubles within 7000-8000 years (increasing from approximately 0.07 to approximately 0.15 wt.% total water). Hydration values are considered to be minimum values as devitrification and/or erosion can remove or render un-analyzable the outermost portion of the hydration rind. Further, FTIR spectroscopy does not lend to analyzing the very edge of a sample unless the edge is orthogonal to the polished surface. Our work suggests that hydration profiles can be used to quantitatively date some young lavas.

Schilling (pers. comm.) reported that these samples exploded, or "popped," on the deck of the ship, similar to what was reported for the 2pi D43 popping rock. We therefore anticipated that they may not have degassed significantly. The goal of this study is to discuss the origin of their volatiles (primary vs. secondary) and the amount of degassing. In terms of major, trace and isotopic compositions, the samples are very similar to the other basalts from this location, following the same along-ridge spatial variations, with a strong influence from the Sierra Leone plume at 1.7 degrees N. Unlike 2pi D43 (vesicularity of 17-18 vol%), our samples have low vesicularities ( or =0.9) between Cl and K, F and P, and H2O and Ce, indicate that Cl, F and H2O did not degass significantly. When plotted against the distance along the ridge axis, we find that the F/P (and Cl/K, to a smaller extent) increase with proximity to the Sierra Leone hotspot, and correlate with radiogenic isotopes. Thus these volatile enrichments reflect source variation. When plotted against Nb and Dy, respectively, CO2 and S do not show any clear tendencies. The trend (R2=0.7) between the CO2 contents and their calculated H2O-CO2 saturation pressures (Psat, 315-526 bar) indicates that some of the CO2 variation is due to equilibrium degassing of a CO2-rich fluid phase (77-98 mol% CO2). By comparing the Psat with the collection pressure (3440-4530 mbsl, i.e. 337-444 bar), we found that half of the samples are affected by variable degrees of supersaturation (up to 82 bars in the deepest sample with the smallest vesicularity). This non-equilibrium state could be caused by a delay in bubble formation due to rapid ascent rates. Finally, unlike CO2, S is poorly correlated with Psat, but displays a very good correlation with FeO*, indicating S saturation and partitioning of S into a sulfide phase rather than into a fluid phase.

Current debate centers on the spatial uniformity of upper mantle fO (sub 2) and its constancy through geologic time. We use iron K-edge X-ray absorption near-edge structure (mu XANES) spectroscopy to provide Fe (super 3+) /Sigma Fe ratios of submarine mantle-derived basalts from mid-ocean ridges (MORB) as a proxy for fO (sub 2) . A global survey of primitive (>8.75 wt% MgO) MORB glasses at spreading centers, unaffected by plumes, reveals a decrease in Fe (super 3+) /Sigma Fe ratio of 12% relative with indices of mantle enrichment such as (super 87/86) Sr, (super 208/204) Pb, Ba/La, and Rb/Sr ratios. The strong negative correlation between upper mantle fO (sub 2) and enrichment recorded by MORB glasses contrasts with the positive relationship hinted at by abyssal peridotite oxybarometry (e.g. Ballhaus, CMP, 1993) and the general prediction of a positive correlation born of the expectation that Fe (super 3+) can be treated as more incompatible than Fe (super 2+) during mantle melting. These data unequivocally link upper mantle oxidation state to mantle source enrichment. EMORB generation is commonly attributed to subduction-related processes. That EMORB is more reduced than NMORB implies that deeply subducted and recycled lithologies, such as anoxic sediment, may be more reduced than ambient mantle. Negative correlations between traditional tracers of recycled sediment (e.g. +Nb anomaly, high (super 87/86) Sr, high LILE/LREE) and redox support this hypothesis. Preservation of redox signatures on plate-recycling timescales of hundreds of millions to billions of years would require the mantle to be very poorly buffered. Alternatively, MORB Fe (super 3+) /Sigma Fe ratios may be generated in situ beneath ridges as a function of variable carbon content. The shallow MORB source is too oxidized to stabilize graphite (Cottrell and Kelley, EPSL, 2011) and carbon exists as oxides. Decreasing fO (sub 2) with increasing depth eventually stabilizes reduced carbon species (diamond, carbides, alloys), however, and a (sub CO2) may buffer mantle assemblages. Upon ascent, reduced carbon in upwelling mantle must oxidize, reducing Fe in the process such that more carbon-rich mantle would arrive at the surface with a lower Fe (super 3+) /Sigma Fe ratio. We cannot directly correlate Fe (super 3+) /Sigma Fe ratios with CO (sub 2) concentrations because submarine basalts have variably degassed CO (sub 2) ; however, the unequivocally carbon-rich sample 2pi D43 (popping rock) does record a low Fe (super 3+) /Sigma Fe ratio. CO (sub 2) variations on the order of 80 ppm in the mantle source would explain the range of MORB/EMORB Fe (super 3+) /Sigma Fe ratios we observe, indicating a possible range of carbon concentrations in subduction-related lithologies. The relationships between MORB Fe (super 3+) /Sigma Fe ratios, trace elements, and isotopes are consistent with modeled mixtures of depleted melts and low-degree carbonatitic melts of ancient subducted igneous crust plus 5-15% sediment (Stracke et al., G3, 2001) using the near-solidus carbonatitic partition coefficients of Dasgupta et al., Chem Geol, (2009). It may be that low degree carbonatitic melts even act through geologic time to scavenge and fractionate trace elements, creating enriched high-carbon reservoirs. Low Fe (super 3+) /Sigma Fe ratios, and even EMORB itself, may therefore herald greater carbon concentrations, and the influence of low-degree carbonatitic melts, in Earth's mantle.

Another six-fold coordinated structure, seifertite, has also been found to exist in the SNC meteorites and has a high pressure stability field near the base of the CMB. The compressibility of this structure (alpha -PbO (sub 2) -type) may be important if regions of the lowermost mantle are silica-rich, either from the introduction of silica-oversaturated material from subduction (Nakagawa, 2010) or by other core-mantle interactions (Knittle, 1991). Under stable heating and quasi-hydrostatic stress conditions, we found that the CaCl (sub 2) type undergoes a phase transition to the alpha -PbO (sub 2) type at 130-140 GPa and 2500 K likely with a positive Clapeyron slope in both pure and Al (sub 2) O (sub 3) -bearing (10 mol%) SiO (sub 2) . This phase transition would occur at a greater depth than the perovskite to post-perovskite transition in basaltic materials (Grocholski, 2012) at the lowermost mantle. Our density measured at 1 bar (4.355 g/cm (super 3) ) is the highest among the reported silica polymorphs, allowing for a well-constrained bulk modulus (K (sub 0) = 322 GPa), and is in excellent agreement with recent first-principles calculations (Driver, 2010). We found very little change in bulk sound speed across the CaCl (sub 2) -type to seifertite transition. If shear wave velocity decreases at the transition to seifertite as suggested by some computational studies (Karki, 1997), this silica transition may provide an alternative explanation for the discontinuities with a shear wave velocity decrease found at depths greater than the D" discontinuity.

Prior to MRO, studies were largely focused on the distribution, morphology, and sediment pathways of dunes. With the higher resolution provided by HiRISE, detailed measurements of ripple and dune migration, and derivation of sand flux and abrasion rates, are possible. Of 88 image pairs examined from 77 degrees S to 86 degrees N, 42 (48%) exhibit no detectable change (that is, down to approximately 3 pixels, or 0.75-0.9 m), 36 (41%) show bedform migration, and 10 (11%) are inconclusive. Migration rates range from the limit of resolution to 12 m per Earth year. Martian dunes and ripples migrate over diverse areas of the planet, with the north polar erg the most prevalent geographic region for displacement. Active bedforms tend to have dark tones and crisp textures, with inactive features commonly lighter in tone and many having ridge-like morphologies. As of yet, no geographic, latitudinal, topographic, or albedo correlations, nor any linkage to results from global circulation models, have come from the analyzed data. Rather, migration may be tied to very local conditions where a sufficient frequency of gusts initiates saltation, which is then sustained by the low impact thresholds on Mars. Sub-pixel registration and correlation using COSI-Corr can quantitatively measure displacements over an entire scene down to scales of 1/3 of a pixel or less (so approximately < or = 8 cm). Using these techniques, sand fluxes have been derived for the Nili Patera dune field. Fluxes between Ls = 268 degrees to 330 degrees (northern winter) are approximately 2.3 m3 m-1 yr-1. These values, and estimated rock abrasion rates of 1-50 mu m yr-1, are equivalent to those estimated in Victoria Valley, Antarctica. The reptation/saltation flux is found at approximately 5, similar to results on Earth. Examining Nili images at other dates shows that flux correlates to the seasonal changes in pressure as measured by surface meteorology stations, indicating a lowering of the threshold friction speed or an increase in the frequency of winds above threshold. Mars is a planet for which sand bedforms are moving in many places, with at least some locations having terrestrial-like activity. Past climates with faster wind speeds or lower threshold values in a higher density atmosphere are only necessary to explain migration of granule-coated or indurated bedforms. Future techniques, instruments, and missions promise to further increase our understanding of dune and ripple movement on Mars.

In particular, Mn oxides scavenge nutrients and metals, degrade complex organics, and oxidize a variety of inorganic contaminants. The "reactivity" of Mn oxides, however, is highly dependent upon crystallite size, composition, and structure, which are largely determined by environmental factors such as solution chemistry. It is has been suggested that most Mn oxides in terrestrial and aquatic environments are formed by microbial activity; indeed, a diversity of Mn(II)-oxidizing bacteria and fungi have been isolated and their mineral byproducts are consistent with those observed in natural systems. Previous studies showed that Mn(II)-oxidizing Ascomycete fungi produce highly-disordered, nanocrystalline Mn oxides that are structurally similar to synthetic delta -MnO2 or natural vernadite. Unlike related studies with Mn-oxidizing bacteria, Mn oxides produced by these fungi did not "age" or transform to more crystalline mineral phases with time. We hypothesize that fungal growth conditions, in particular the low concentration of cations, are inhibiting secondary mineral formation. The overall goal of this research is to examine the structure and speciation of fungally-precipitated Mn oxides with respect to fungal species, time, and concentration of soluble Mn(II), Na, and Ca - three environmentally relevant cations that promote the transformation of delta -MnO2 to more crystalline mineral phases such as feitknechtite, birnessite, or rancieite. For this study, we examined the Mn oxides formed by different species of Mn(II)-oxidizing fungi (Pyrenochaeta sp., Stagonospora sp., Plectosphaerella cucumerina., and Acremonium strictum). Isolates were grown for 8 or 16 days in a nutrient lean media consisting of yeast extract, trace elements and 0.2 mM MnCl2 supplemented with varying concentrations of Na, Ca, or Mn(II) compounds. The concentration of Mn(II) in solution was held constant (0, 0.15, 0.5, 1.0 and 1.5 mM) only in the Mn-supplemented experiment. Mycogenic Mn oxides were analyzed using X-ray diffraction (XRD) and extended X-ray absorption fine structure (EXAFS). During the experiments, it was observed that each fungal species responded differently to the varying growth media. The addition of Na inhibited growth and oxidation of several species, and the highest concentrations of Mn in solution proved toxic to a few species. Fungi grown with Na produced a highly-disordered phyllomanganate phase similar to birnessite or vernadite. During growth in Ca-rich solutions, however, a more crystalline rancieite-like phase was formed with 10Aa interlayer spacing that collapsed to 7Aa upon drying. Although a feitknechtite-like phase was expected in experiments with Mn concentrations greater than 0.5 mM, a birnessite-like phase was formed. This suggests that a more complex solution chemistry is required for transformation to the more crystalline phases, or the presence of the fungal biomass is inhibiting the ripening of the Mn oxides.

Together, they represent the largest single family of achondrite meteorites delivered to Earth, and have been spectrally linked to the asteroid 4 Vesta, the largest remaining basaltic protoplanet. However, this spectral link is non-unique as many basaltic asteroids likely formed and were destroyed in the early solar system. Recent work suggested that Vesta may be an unlikely parent body for the diogenites based on correlations between trace elements and short-lived isotope decay products, which would be unlikely to survive on a body as large as Vesta due to its long cooling history [1]. Recent analyses of terrestrial and martian olivines have demonstrated that trace element spatial distributions can preserve evidence of their crystallization history even when major elements have been homogenized [2]. We have mapped minor elements including Cr, Al, and Ti in seemingly homogeneous diogenite orthopyroxenes and found a variety of previously unobserved textures. The pyroxenes in one sample (GRA 98108) are seemingly large grains of variable shapes and sizes, but the trace elements reveal internal grain boundaries between roughly-equal sized original subgrains, with equilibrated metamorphic triple junctions between them and trace element depletions at the boundaries. These trends suggest extraction of trace elements by a magma along those relict grain boundaries during a reheating event. Two other samples show evidence of fracturing and annealing, with trace element mobility within grains. One sample appears to have remained a closed system during annealing (MET 01084), while the other has interacted with a fluid or magma to move elements along annealed cracks (LEW 88679). These relict features establish that the history of diogenite pyroxenes is more complex than their homogeneous major element compositions imply. Many trace element analyses are performed using either bulk rock techniques or spot analyses, and these maps suggest those types of analyses likely sample variable trace element abundances even within otherwise homogeneous grains, rendering their results difficult to interpret. Consequently, the correlation discussed previously between trace elements and short lived isotopes has likely been impacted by post-magmatic alteration and cannot solely be used to argue that HED's cannot be derived from Vesta. Furthermore, these maps strengthen the HED-Vesta link by suggesting that the diogenites underwent an extended history of cooling, reheating, partial melting, impact fragmentation, fluid/melt migration, and finally re-annealing. These complicated steps are particularly noteworthy as the pyroxene cumulate layer on the asteroid Vesta should lie beneath the eucritic crust, implying that early impacts were able to penetrate that crust and affect the diogenite layers early in Vesta's history, most likely while the asteroid was still hot enough to allow for annealing and regrowth of fractured grains.

The early Paleogene was a greenhouse climate state, upon which was superimposed a series of transient, extreme global warming events known as hyperthermals. During the summer of 2011, the Bighorn Basin Coring Project (BBCP) drilled two overlapping cores at three sites in the Bighorn Basin (Basin Substation, Polecat Bench, and Gilmore Hill) in an effort to develop high-resolution proxy records across early Paleogene hyperthermal events. The Basin Substation and Polecat Bench sites targeted the largest Paleogene hyperthermal event, the Paleocene-Eocene Thermal Maximum (PETM), and the Gilmore Hill site targeted two smaller hyperthermal events, ETM2 and H2, which occurred after the PETM. Previous analysis of outcrop exposures indicated that PETM sediments at the Basin Substation site generally contained a higher total organic carbon content than sediments at Polecat Bench and Gilmore Hill. Higher weight percent organic carbon often corresponds to better preservation of organic molecules for geochemical analyses. Therefore, for this study, we focused on analyzing the second core drilled at Basin Substation (BBCP-BSN11-1B) for preliminary BBCP organic geochemical analyses. More than 300 samples were collected from the 138.6 m core. n-Alkanes have been extracted and isolated from approximately 100 of these samples. High molecular weight n-alkanes (C25-C35) with odd-over-even-predominance of chain lengths are used as diagnostic biomarkers of vascular plants in sedimentary rocks because of their high preservation potential and resistance to isotopic exchange. High molecular weight, odd-carbon numbered n-alkanes are being quantified and stable carbon isotope ratios are being measured to develop a high-resolution compound-specific delta 13C record across the PETM. This high-resolution n-alkane delta 13C record and n-alkane abundance data from unweathered core material have the potential to reveal changes in carbon cycling across the PETM at unprecedented stratigraphic resolution and to provide information about the relative durations of the PETM onset, body, and recovery. PETM conditions in the Bighorn Basin were not ideal for organic matter preservation, perhaps due to high temperature and extreme seasonal precipitation, and even unweathered core material from Basin Substation does not preserve an abundance of n-alkanes. Carbonaceous shale and laminated mudstone appear to have higher abundances of n-alkanes than massive mudstone, siltstone, and sandstone lithologies. n-Alkane abundances and delta 13C values from three carbonaceous shales in the Basin Substation core will be compared to samples collected from the same three carbonaceous shales exposed in outcrop to assess the impact of recent weathering on n-alkane preservation in outcrop exposures.

Pentacyclic triterpenoids are synthesized almost exclusively by angiosperms whereas conifers produce the tricyclic diterpenoids. Many previous studies have focused on the use of di- to triterpenoid ratios to reconstruct floral changes in the geologic past, however few studies have compared terpenoid-based paleoflora proxies to pollen or megafossils. Prior reconstructions also did not take into account differences in biomarker production between plant functional types, such as deciduous and evergreen plants, which can be quite large. To investigate the use of terpenoids as paleoflora proxies, we examined sediments from the Bighorn Basin (Wyoming, USA) where ancient megafloras have been studied in detail. We analyzed di- and triterpenoid abundances as well as plant leaf waxes (n-alkanes) and other biomarkers in a total of 75 samples from 15 stratigraphic horizons from the late Paleocene (62 Ma) to early Eocene (52.5 Ma). By comparing terpenoid ratios with abundances estimated from plant megafossils, we can evaluate the utility of terpenoids as paleovegetation proxies. In nearly all samples, angiosperm triterpenoids are significantly lower in abundance than conifer diterpenoids. This contrasts with leaf fossil data that indicate paleofloras were dominated by angiosperms in both abundance and diversity. Traditional use of terpenoid paleovegetation proxies would therefore significantly overestimate the abundance of conifers, even when accounting for plant production differences. To determine if this overestimate is related to the loss of angiosperm triterpenoids (rather than enhanced production of diterpenoids in the geologic past), we compared angiosperm triterpenoids to the n-alkane leaf waxes, which are produced primarily by angiosperms. After accounting for concentration differences between these two biomarker groups in modern plants, it is apparent that triterpenoid amounts are still significantly lower than expected in nearly all of our samples. We suggest a loss of triterpenoids might be related to enhanced diagenesis of triterpenoids in oxidizing terrestrial sediments. In order to reconstruct paleovegetation we propose a new method that employs a ratio of diterpenoids (conifers) to n-alkanes (angiosperms) and accounts for biomarker biomass abundance differences. Using this approach, we estimate paleovegetation communities similar to those predicted from megafossils. Although this new biomarker-based paleovegetation proxy works for sites within the Bighorn Basin, we stress this approach will need to be evaluated for other depositional environments using pollen or megafossil data.

Hyperthermals shed light on connections between the carbon cycle and climate that are important for understanding anthropogenic global warming, and as a result have been the subject of intense study, particularly in deep-sea cores. Hyperthermals are less well known in the terrestrial realm. The goal of the Bighorn Basin Coring Project (BBCP) is to produce high-resolution records that reveal changes in climate, landscapes and ecological communities that occurred in the middle of the North American continent during three hyperthermals. In the summer of 2011, BBCP scientists cored fluvial rocks representing the Paleocene-Eocene Thermal Maximum (PETM; approximately 56 Ma), Eocene Thermal Maximum 2 (ETM2; approximately 53.7 Ma) and H2 ( approximately 53.7 Ma). These cores provide continuous sections of fresh rock in direct stratigraphic superposition that are being analyzed for chemical and physical properties as well as fossils. High depositional rates at all three sites (30-50 cm/thousand years) permit resolution of events on a millenial timescale. The PETM was double cored at two sites, Basin Substation and Polecat Bench, that provide contrasting local environments. Basin Substation sediments were deposited on wet floodplains near the eastern flank of the Bighorn Basin and have higher concentrations of organic microfossils and biomarkers. Early studies of the approximately 140 m-thick Basin Substation cores, which were drilled with municipal water only, have focused on pollen and spores, n-alkanes, polycyclic aromatic hydrocarbons, GDGTs, plant mesofossils, and the isotopic composition of dispersed organic matter. The Polecat Bench site was closer to the depositional axis of the Bighorn Basin, but floodplain sediments were generally better drained and have higher concentrations of oxidized iron and calcium carbonate. Early work on these two cores (one 130 m drilled with only municipal water, and the other 245 m long drilled with polymer drilling fluid) has focused on paleosol minerals and carbon isotope composition of pedogenic carbonate nodules. ETM2 and H2 were double cored at the third site, Gilmore Hill, with one core being 67 m and the other 202 m deep, both drilled with municipal water only. The Gilmore Hill cores penetrated fluvial sands and oxidized floodplain paleosols. Early work on these cores has concentrated on paleosol morphology, mineral composition, and carbon isotope composition of pedogenic carbonate nodules. All cores also have down-hole logs, multi-sensor core logs (magnetic susceptibility and density), color reflectance, high-resolution linescans, visual core descriptions, XRF scans, and close correlation with paleontological and geological work in nearby outcrop sections. This talk will provide background information on scientific goals, geological setting and coring methods for talks in this session relating to the BBCP.

Several proposed sources of this carbon include ocean-floor methane clathrates, thermogenic methane, permafrost oxidation, and burning of peat and/or shallowly buried coal, but the exact source(s) remain unknown. The Paleocene was a time of extensive terrestrial organic carbon burial and some authors have suggested that a change in climate induced burning of the (super 13) C-depleted carbon deposits. In this study a diverse suite of polycyclic aromatic hydrocarbons (PAHs), organic compounds produced as aerosols during combustion, were characterized and quantified in order to investigate evidence for fire during the PETM. We sampled intervals of cores from Basin Substation, Bighorn Basin, Wyoming, USA, collected as part of the Bighorn Basin Coring Project (BBCP). PAHs were evaluated using gas chromatography-mass spectrometry (GC-MS) in selective ion monitoring (SIM) mode. We found a range of two- to seven-ring PAHs from napthalene to coronene. For all samples the abundances of individual PAHs range from 0.1-100 ng/g dry sediment. Total PAH abundance (sum of 16 PAHs) is reduced in samples from the body of the PETM carbon isotope excursion relative to samples from the latest Paleocene (300 ng/g and 40 ng/g, respectively), although there is a spike in total PAH concentration (2300 ng/g) at or just before the onset of the PETM. The stratigraphic pattern of PAH abundance is consistent with a peak in wildfires at or just before the onset of the PETM, followed by a decrease in the body of the PETM, but also may reflect decreased preservation of organic matter during the hotter and more seasonally dry climate that this region experienced during the PETM. The latter explanation is consistent with a general decrease in organic matter preservation during the PETM interval in this core. Higher relative abundance of high molecular weight PAHs in PETM samples suggests hotter fire temperatures at that time, regardless of fire occurrence. A literal interpretation of the PAH record from the Basin Substation core would suggest more intense burns but less wildfire activity during the PETM, but the effect of changes in organic matter preservation must be eliminated before this interpretation can be accepted.

This event, known as the Paleocene-Eocene thermal maximum or PETM, reflects the geologically rapid release of isotopically light carbon into the atmosphere and is associated with global warming of approximately 5-8 degrees C. While numerous studies have investigated the timing and magnitude of the PETM CIE, significant uncertainty remains regarding the amount and pacing of the global carbon isotope shift. The Bighorn Basin Coring Project recently collected the first scientific drill cores preserving high-resolution, stratigraphically continuous records of the PETM in continental environments and providing a new suite of data from un-weathered rocks. We report data from pedogenic carbonate nodules sampled at >200 levels within two adjacent drilling locations at Polecat Bench in the Bighorn Basin. These data provide a continuous record of the evolution of carbon isotope ratios in Bighorn Basin paleosols over a period of approximately 500 Kyr spanning the P-E boundary. delta 13C data from the nodules reveal a CIE of approximately 7 ppm with considerable structured isotopic variability at the onset of the PETM and a smooth recovery back to pre-PETM baseline conditions. Relative to previous studies, this higher-resolution dataset better constrains the pattern and pace of the carbon isotope changes and records higher variability during the onset of the event, but confirms existing results of the general shape and approximately 7 ppm magnitude of the CIE at this locality.

Lightning has now been documented at 154 volcanoes in association with 394 eruptions, a significant increase from the earlier numbers of 89 volcanoes and 240 eruptions. Lightning and electrification at volcanoes are important because they represent a hazard in their own right, they are a component of the global electrical circuit, and because they contribute to ash particle aggregation and modification within ash plumes. The role of water substance (water in all forms) in particular has not been well studied. The Volcanic Explosivity Index (VEI) was determined for 177 eruptions. Eight percent of VEI=3-5 eruptions have reported lightning, and 10 percent of VEI=6, but less than 2 percent of those with VEI=1-2, suggesting consistent reporting for larger eruptions but either less lightning or under-reporting for small eruptions. Ash plume heights (142 observations) show a bimodal distribution with peaks at 7-12 km and 1-4 km. The former are similar to heights of typical thunderstorms and suggest involvement of water substance, whereas the latter suggest other factors contributing to electrical behavior near the vent. The distributions of the latitudes of volcanoes with lightning and eruptions with lightning roughly mimic the distribution of all volcanoes; flat with latitude. Meteorological lightning, on the other hand, is common in the tropics and decreases markedly with increasing latitude as the ability of the atmosphere to hold water decreases poleward. This finding supports the idea that if lightning in large eruptions depends on water substance, then the origin of the water is primarily magma and not entrainment from the surrounding atmosphere.

In order to develop chemical tools for inferring closed-canopy forests in the geological record we have studied the relationships among foliar carbon isotope compositions (delta 13C), litter flux and leaf-wax properties in the context of environmental gradients (light, moisture, CO2) within extant forest canopies. Leaves in a tropical closed-canopy forest exhibit a greater range of vertical isotopic enrichment (10 ppm) compared with similarly sampled temperate open-canopy forest (6 ppm). We used these data and a statistical resampling (bootstrap) method to form expectations for isotopic variation in fossil leaf assemblages and sediments that formed under different forest types. According to this model, there is a robust likelihood of identifying canopy closure by isotopic analysis of as few as 50 fossil leaves selected randomly. By sampling many thousands of leaves, the model estimates the influence of leaf biomass on organic matter in ancient soils and other terrestrial archives. The model predicts that soil organic matter in a tropical closed-canopy will be approximately 1 ppm more depleted than in a temperate open-canopy forest. Modeled closed-canopy litter coincides with observed delta 13C values for litterfall and humic soils in the tropical forest. Despite variability within a canopy and among individual leaves and species, sedimentary organic matter potentially captures global-scale biome patterns, provided diagenetic influences can be constrained. Thus to allow insights to isotopic differences between litter input and preserved signals in ancient environments, we can incorporate biomarker abundance and isotopic data for six n-alkanes (n-C25 to n-C35) into the model. This model allows us to predict the sediment lipid profiles that would result from a variety of canopy conditions and taxonomic dominance patterns.

In this set of experiments, we run currents over substrates with characteristic roughness scales, h (sub r) , ranging over approximately 3 orders of magnitude from smooth, through 250 mu m sandpaper, 0.1-, 1-, 2-, 5-, and 10 cm hemispheres. As substrate roughness increases, runout distance increases until a critical roughness height, h (sub rc) , is reached; further increases in roughness height decrease runout. The critical roughness height appears to be 0.25-0.5 h (sub tb) , the thickness of the turbulent lower layer of the density currents. The dependence of runout on h (sub r) is most likely the result of increases in substrate roughness decreasing the average current velocity and converting that energy into increased turbulence intensity. Small values of h (sub r) thus result in increased runout as sedimentation is inhibited by the increased turbulence intensity. At larger values of h (sub r) current behavior is controlled by much larger decreases in average current velocity, even though sedimentation decreases. Scaling our experiments up to the size of real volcanic eruptions suggests that landscapes must have characteristic roughness h (sub r) >10 m to reduce the runout of natural PDCs, smaller roughness scales can increase runout. Comparison of relevant bulk (Reynolds number, densimetric and thermal Richardson numbers, excess buoyant thermal energy density) and turbulent (Stokes and settling numbers) between our experiments and natural dilute PDCs indicates that we are accurately modeling at least the large scale behaviors and dynamics of dilute PDCs.

From the summit of Santa Maria the frequent (1 per hour) explosions and continuous lava flow effusion may be observed from a vantage point, which is at a approximately 30 degree elevation angle, 1200 m above and 2700 m distant from the active vent. At these distances both video cameras and SLR cameras fitted with high-power lenses can effectively track blocky features translating and uplifting on the surface of Santiaguito's dome. We employ particle image velocimetry in the spatial frequency domain to map movements of approximately 10X10 m (super 2) surface patches with better than 10 cm displacement resolution. During three field campaigns to Santiaguito in 2007, 2009, and 2012 we have used cameras to measure dome surface movements for a range of time scales. In 2007 and 2009 we used video cameras recording at 30 fps to track repeated rapid dome uplift (more than 1 m within 2 s) of the 30,000 m (super 2) dome associated with the onset of eruptive activity. We inferred that the these uplift events were responsible for both a seismic long period response and an infrasound bimodal pulse. In 2012 we returned to Santiaguito to quantify dome surface movements over hour-to-day-long time scales by recording time lapse imagery at one minute intervals. These longer time scales reveal dynamic structure to the uplift and subsidence trends, effusion rate, and surface flow patterns that are related to internal conduit pressurization. In 2012 we performed particle image velocimetry with multiple cameras spatially separated in order to reconstruct 3-dimensional surface movements.

To test between these two hypotheses, we present major element, S and Cl concentrations (EMP), trace element concentrations (LA-ICPMS), volatile concentrations (FTIR) and Fe (super 3+) /Sigma Fe ratios (mu -XANES) determined from naturally glassy olivine-hosted melt inclusions with <2% post-entrapment crystallization from single eruptive events at Sarigan, Alamagan, Agrigan, Guguan, Pagan, and Maug volcanoes, and submarine glasses from Pagan and NW Rota-1 volcanoes and the Mariana Trough back-arc spreading center. Near-undifferentiated glass compositions from Pagan and NW Rota-1 submarine volcanoes have high MgO (7.9 - 11.1 wt%) and Fe (super 3+) /Sigma Fe ratios that are significantly oxidized over MORB, ranging from 0.211 to 0.237. Melt inclusions and Mariana Trough glasses range from 2.0 - 7.4 wt% MgO and are consistent with variable quantities of olivine + or - clinopyroxene + or - plagioclase + or - magnetite fractionation as well as CO (sub 2) + or - H (sub 2) O + or - S degassing. Fe (super 3+) /Sigma Fe ratios in arc melt inclusions range from 0.18 - 0.34 and in back-arc related samples from 0.17 - 0.20. Variations in Fe (super 3+) /Sigma Fe ratio along observed liquid lines of descent (LLDs) are slightly oxidizing, consistent with the fractionation of Fe (super 2+) -bearing minerals, or moderately reducing when either sulfur is behaving as a volatile or when magnetite is fractionating, but are insufficient in magnitude to explain why arc basalts are more oxidized than MORB. Melts last in equilibrium with the mantle (i.e. primary melts) are reconstructed from measured compositions by backtracking along empirical and modeled LLDs to yield primary Fe (super 3+) /Sigma Fe ratios. Pressures and temperatures of primary melt equilibration are calculated using the Si-thermobarometer developed by Lee et al. [2009] (EPSL 279(1-2), 20-33). Primary melt fO (sub 2) ranges from QFM+0.1 to QFM+0.5 for back-arc magmas and from QFM+1.0 to QFM+1.6 for the arc magmas, which is significantly oxidized over MORB primary melts ( approximately QFM). This supports previous observations that subduction influence and oxidation are correlated on a global scale. Mariana arc volcanoes span a range in trace element signatures of subduction influence, from aqueous fluid to sediment-melt dominant but there is no correlation between primary melt fO (sub 2) and either indices of specific slab signatures or mantle composition. This suggests either that the Mariana arc mantle wedge may be buffered near QFM+1.2 + or - 0.26 (n = 55) or that the fO (sub 2) of material escaping the subducting slab is near QFM+1.2 and the Mariana mantle wedge is at a steady state with respect to fO (sub 2) . These results suggest that oxidized species transported from the slab to the mantle wedge may have no distinct preference for aqueous fluids or melts in the Mariana system.

We used an array of 5 radio-triggered cameras to collect synchronized images of the lava dome at 1 minute intervals from a distance of approximately 2.5 km with an angular aperture of approximately 7 degrees. The images of the lava dome have a resolution of approximately 0.05 m/pixel. Using cross correlation of the images we constructed 3D point clouds of the dome at each time with nominal point spacing of approximately 1 m. Tracking each point through space and time provides a 3D velocity field of the dome with 1 minute temporal resolution. We estimate velocity detection limits of approximately 0.1 m/min for instantaneous velocities and 0.01 m/min for those averaged over >1 hour. The largest variations in velocity occur near the dome summit where approximately 1.5 m of inflation-deflation can occur in as little as 10 minutes in a 15-20 m diameter region. As other velocities radiate from this region, this region likely overlies the conduit. Such local deflation events appear to be correlated with inflation of the Santiaguito dome in general as measured by tiltmeter. Velocities in the region south of the "conduit" are steadier with peak velocities of approximately 2.7 m/h. Our work demonstrates how an array of inexpensive cameras may be used to collect high frequency, quantitative observations of rapidly flowing or deforming lava flows.

The Galema Ridge is superimposed on the eastern plateau rim of the northern MER. It was built up through an en-echelon dike swarm and associated cinder cones and lavas. This 70 km-long, nearly equal 2 Ma-old magmatic belt is now paralleled by the recent and ongoing intrusive-volcanic activity focused along the Wonji Fault Belt in the eastern floor of the MER. An understanding of the magmatic plumbing system of the Galema Ridge can reveal the cause for step-wise migration of magmatic activity across the MER. The Galema dikes comprise a bimodal suite of hawaiitic basalts and peralkaline rhyolites. The mafic rocks have trace element patterns resembling those of the Wonji basalts, suggesting similar parental magmas. However, major element oxides ratios, and in particular CaO/Al (sub 2) O (sub 3) , place the Galema mafics closer to the basalts of the Silti-Debre Zeyit Fault Zone on the western floor of the MER. The ratio data suggest that augite was a more important phase than plagioclase during mafic fractional crystallization under Galema, and that fractional crystallization operated at depths similar to those inferred for the Silti-Debre Zeyit Fault Zone, substantially deeper than beneath the intervening Wonji Fault Belt. Continued fractionation at Galema ended with production of peralkaline rhyolite magmas with 66% SiO (sub 2) , marked by a transition for K and Ba from incompatible to compatible, expressing the observed dominance of anorthositic feldspar in the fractionating assemblage. The rhyolitic dikes and lavas exhibit depletion in heavy rare earth elements (REEs) and especially middle REEs. The absence of this pattern from the mafic rocks suggests that amphibole played a significant role in controlling trace element variations in the peralkaline magmas, consistent with the presence of alkali amphibole in the rhyolite mineralogy. The REE depletion patterns in the Galema rhyolites are not matched in the MER peralkaline rhyolites, and the role of amphibole in the magmatic evolution of the earlier suite may have resulted from fractionation at greater depth and/or enrichment of fluorine. Our preliminary data therefore indicate that with a shift of the zone of dike injection from rift margin to rift floor, magmatic fractionation shallowed in conjunction with crustal thinning.

Thus far, the focus has been on analyzing boron in volcanic rocks and olivine inclusions. However, these materials always experience some degree of late processing on their way to the surface (alteration, crystallization, change in structure, etc.). As of now, the boron content and isotopic ratio of the mantle end-member is only assumed through mass balance calculations (Chaussidon & Marty, 1995). Diamonds, on the other hand, would be a more ideal material to analyze for boron, as it does not undergo significant processing while on its way to the surface. Boron-containing diamonds are well known but extremely rare; they are referred as type IIb diamonds. They are highly valuable in the gem market, as the presence of boron in the diamond structure gives rise to the blue color, such as in the Hope diamond. Only a few boron analyses have been undertaken on type IIb natural diamonds, however, it is generally accepted that their boron concentration is approximately 1 ppm or lower. The combination of rarity, high value, and low boron content are the most likely reasons why geologists have not yet performed boron analyses on blue diamonds. This study used various spectroscopic methods and time-of-fight (ToF-) SIMS, which are non- or nearly non-destructive techniques, to characterize and analyze for boron in natural type IIb blue diamonds, including the well-known Hope diamond. Results obtained by Fourier Transform Infrared (FTIR) and phosphorescence spectroscopies on 103 diamonds will be presented and compared to some analyses of boron contents measured using ToF-SIMS. ToF-SIMS analyses gave spot (50X50 mu mXfew nm deep) boron concentrations as high as 8.4+ or -1.1 (atomic) ppm for the Hope diamond to less than 0.08 ppm in other blue diamonds, with an overall average value of approximately 1 ppm. ToF-SIMS analyses revealed strong zoning of boron in some diamonds, which was confirmed by mapping active boron using synchrotron FTIR. ToF-SIMS gives the spectrum of all the masses at once, so both 11B and 10B were detected. However, the counts on 10B were too low at the counting time we used (several hours) to provide significant delta 11B measurements. We observed that there is not a strong correlation between the amount of boron and the color intensity in type IIb diamonds (Gaillou et al., 2012). However, the deep-blue colored diamonds are always associated with a "high" boron content, and therefore, future attempted measurements of boron isotopic ratios should be conducted on deep blue (and unfortunately, valuable) diamonds, using either a much longer counting time, or a different ion mass spectrometer (with different standards), that would consume more material. This study shows that the range of boron concentration, even if in the lower range of instrument detectability, should soon be able to provide boron isotopic measurements, and perhaps gives insights into the origin of boron in diamonds, e.g. from a subducted slab and/or from primitive mantle reservoir.

Experiments were conducted in a cold-seal Ni-rich pressure vessel (Waspaloy) with Ni filler rod, so that experiments were buffered at Delta NNO +1 (+ or -0.5) (Gershwind & Rutherford, 1992) and pressurized with H (sub 2) O (where P (sub total) =P (sub H2O) ). Temperatures ranged from 750-900 degrees C and pressures ranged from 100-300 MPa. Prior to the experiments, detailed petrologic studies were first conducted on the three obsidian samples, which are from Cascade and Mexican arcs. Overall phenocryst abundances in all three samples are low (<2.3%), with little to no microlite crystallization. Despite low phenocryst abundances, the obsidians are saturated in five to seven mineral phases: plagioclase + orthopyroxene + ilmenite + magnetite + apatite + or - clinopyroxene + or - biotite. Eruptive temperatures (+ or -1sigma ), on the basis of Fe-Ti two oxide thermometry (Ghiorso & Evans, 2008), range from 760+ or -18 degrees C to 943+ or -20 degrees C; corresponding Delta NNO values (+ or -1sigma ) range from -0.9+ or -0.1 and 0.7+ or -0.1. Plagioclase compositions span a wide range in each sample (e.g., 9-40 and 30-54 mol% An), despite low phenocryst abundances. Orthopyroxene compositions also span a wide range (< or =15 mol% En), which correspond to (super Fe-Mg) K (sub D(opx-liq)) values that range from 0.18-0.46. Given the low crystallinity, absence of evidence for mixing of magmas, and no apparent change in oxygen fugacity recorded by iron oxides, the progressive loss of water from a melt, through degassing during rapid magma ascent, is a plausible hypothesis to explain the observed variation in phenocryst compositions. This hypothesis is evaluated with the run products from the water-saturated phase equilibrium experiments on the three obsidian samples. The experimental results indicate that the most calcic plagioclase phenocryst in the obsidians record water concentrations of approximately 5-7 wt% and that the compositional range in plagioclase phenocrysts can be attributed to a loss of < or =3 wt% H (sub 2) O from degassing. Similarly, the experiments show that orthopyroxene compositions also vary with dissolved water concentration, with increasing water content favoring Fe-rich orthopyroxene.

To constrain such fluxes, it is required that details of the physical and chemical evolution of the rocks that enter the system at the subduction zone are understood. Subduction-related eclogites are products of igneous, metamorphic, fluid-rock, and tectonic processes acting on ocean floor basalt for 10s of millions of years. These rocks preserve evidence for changes in bulk rock and mineral chemistry, mineral assemblages and microstructures resulting from these processes. We characterize and compare the textures and major and trace element chemistry of blueschist and eclogite from three subduction complexes to evaluate how these processes interact and to assess to what extent chemical and physical changes may be preserved during a complex P-T-t-D history. Coronitic and mylonitic eclogite and blueschist samples from subduction complexes in the Franciscan (CA, U.S.A.), Monviso (Western Alps) and Gruppo di Voltri (Ligurian Alps) represent different depths of subduction, and degrees of deformation and metamorphism, as well as a variable degree of retrogression. Textural observations and the trace element composition of talc inclusions in omphacite suggest that gabbroic rocks preserve some primary magmatic mineral domains through the entire subduction-exhumation cycle. Full recrystallization has obscured all primary domains in finer-grained rocks. There is great variability in the extent to which evidence of metamorphic episodes is preserved. Bulk major and trace element chemistry analysis indicates that all samples are enriched in most trace elements compared to MORB, and at each locality, deformed rocks are more enriched than undeformed samples. Enrichment of the fluid-mobile elements (LILE, and Th, U) is particularly strong in the Franciscan samples. Trace element distributions within minerals testify to which minerals equilibrated with each other, and/or with exotic fluids. Minerals may acquire trace element signatures from precursor minerals, which themselves equilibrated with an earlier fluid, or with the bulk rock following mass transfer on a large scale. The trace element budgets for the three sample suites are dominated by garnet and Ca-silicates such as epidote and titanite, as well as accessory apatite. The LILE are mostly hosted in phengite. The stability of epidote and Ca-rich accessory minerals such as apatite and titanite is critical to understanding budgets of the light to middle REE. Ti in phengite does not depend on deformation or bulk rock compositions; instead, it appears to correlate with fluid activity. The Ba-contents of Franciscan phengite also reflect greater degrees of fluid-rock interactions, or more trace-element-rich alteration fluids. Contrasts between fluid-mobile Ba and relatively-less mobile Ti in phengite suggests that fluid flow is not primarily deformation induced, nor does it correlate with the peak pressure experienced by the rocks. Instead, the effects and greater degrees of fluid-induced alteration in mafic rocks appear to be related to higher T/P conditions of fluid-rock interactions.

Melange bodies adjacent to the Motagua fault system (MFS) of the Guatemala Suture Zone contain evidence of this process. A set of 93 whole rock major and trace element analyses track aspects of the fluid transfer from the channel to the wedge at pressures from 1 to >2 GPa. Published data indicate transfer of alkali silicate and fluid-mobilized large-ion lithophile elements (LILE) such as Ba, Sr, and NH4 (and Li), from both altered oceanic crust and overlying sediments in a paleosubduction setting. PUM-normalized REE patterns for jadeitites vary geographically along the 200 km long exhumation trace in the MFS. The grouped patterns are mostly enriched compared to PUM, variable with respect to N-MORB, and generally flat with a trend toward a concave shape. Both positive and negative Eu anomalies occur. These are probably controlled in part by pyroxene crystal chemistry, in which elements such as Li, Sr, Cr and Ca are variably compatible depending on jadeite content. Relative LREE enrichment in some samples may point to fluid contribution from either OIB or a sediment source. All samples show relative enrichments in the HFSE Ta, Nb, Hf, Zr, U, Th, and the LILE Ba and Cs, contrasted by depletions in K and sometimes Pb or Sr. Most samples are also depleted in the highly compatible elements Cr, Sc and Ni. Our samples show a strong similarity with GLOSS (globally subducted oceanic sediment) and other sediments in terms of their trace-element patterns, but are offset to lower abundances. Jadeitites thus incorporate a strong signature derived from sediments mixed with that from fluid derived from altered oceanic crust. Although many samples show little contribution from infiltrated mantle protolith, some are enriched in Cr and Ni. Enrichment in the HFSE argues for mobility of these elements in aqueous fluids at high P/T conditions in the subduction channel. Jadeite crystallization, while modifying fluids derived from oceanic crustal sources, does provide a tangible record. Variations in this record may reflect either process variation or geographic variation in sediment sampled laterally along the subduction zone. All Guatemalan jadeitites and omphacitites are interpreted as fluid precipitates; some are depleted in LREE, while others are enriched. Thus, LREE enrichment is not an indicator of the formation process of jadeitites (fluid precipitated vs. metasomatic). Instead, LREE enrichment may be an indicator of sediments in the source of the fluids that precipitated jadeitite.

We calculate the fO2 recorded by spinel peridotites using microprobe analysis of spinels calibrated with standards provided by [1] and [2]. We do not observe the correlation, reported by [1], between the Cr# and Delta Fe3+/Sigma FeMossbauer-microprobe of the standards. Rather, we observe a strong correlation (R2=0.85-0.97) between Fe3+/Sigma FeMossbauer and Fe3+/Sigma Femicroprobe, which we use to determine Fe3+/Sigma Fe in spinel unknowns. Peridotites were analyzed from three localities: the Southwest Indian Ridge, the Tonga Forearc, and Cerro Mercedes, Costa Rica. Southwest Indian Ridge samples range from typical depleted abyssal peridotites to peridotites influenced by nearby Bouvet Hotspot. Tonga Forearc samples are from the trench and represent forearc lithospheric mantle. The Cerro Mercedes xenoliths are from a distance of 70km behind the active arc, thus representing back-arc mantle. The ridge peridotites have moderate degrees of hydrothermal alteration, whereas the Tonga peridotites vary from completely fresh to moderately altered. The xenoliths have no hydrothermal alteration, but have undergone minor reaction with the host basalt. The upper mantle fO2 recorded by spinels in these samples, calculated at 10kb and 1150 degrees C, varies with proximity to subducted lithosphere. SWIR peridotite records QFM - 0.8 + or - 0.3 (n = 7; + or - 1sigma ) while peridotite influenced by the Bouvet plume records QFM - 0.3 + or - 0.1 (n = 2). Peridotites from Tonga and Costa Rica record QFM + 1.5 + or - 0.8 (n=4, excluding one outlier at -0.2) and QFM + 1.1 + or - 0.5 (n = 2) respectively. The fO2 we calculate for SWIR agrees very well with [3] for the same locality. Peridotite influenced by the Bouvet hotspot exhibits a similar or slightly elevated oxidation state relative to adjacent sections of SWIR with no Bouvet influence. In contrast, previous work by [3] on peridotite associated with Bouvet hotspot from the Islas Orcadas Fracture Zone found highly reducing fO2s. The Islas Orcadas peridotites are highly altered, however, with almost complete replacement of the primary mineralogy by hydrothermal minerals. Peridotites from Tonga and Costa Rica are more oxidized than abyssal peridotites and record some of the highest reported mantle fO2s . These results suggest that mantle associated with arc volcanism is oxidized relative to the MORB mantle, consistent with the oxidation state of derived basalts. The oxidation state of relatively unaltered peridotites influenced by Bouvet suggests that this hotspot is not reduced relative to ambient SWIR mantle.

To this aim we conducted twice-weekly delta (super 18) O and salinity measurements on waters collected from marine laboratories on opposite sides of the Isthmus of Panama; Naos in the Gulf of Panama (Tropical Eastern Pacific) and Galeta in the southwestern Caribbean (SWC). Data reveal the strong transition from dry to rainy season in the Gulf of Panama where upwelling in the dry-season increases coastal salinity (up to 34.4 psu) and delta (super 18) O values (-1.0 to 0.0ppm), whilst the rainy season lowers marine delta (super 18) O values (as low as -1.6ppm) due to the 2-3 fold increase in rainfall. In contrast, the SWC experiences no upwelling, but does reveal a significant amount of freshening caused by increasing rainfall at the transition from boreal spring to summer. Despite the greater disparity in the average rainfall between dry and wet seasons near Galeta (SWC) compared with the Gulf of Panama, a decrease in marine delta (super 18) O of only nearly equal 0.5ppm on average was found between seasons for SWC waters. The higher salinity and higher delta (super 18) O values in the coastal waters of the SWC are due in part to large scale climatic differences principally that the Caribbean experiences higher evaporation than rainfall. The relationship between salinity and delta (super 18) O in the Gulf of Panama is strong (R (super 2) =0.87; p<0.001), but is much less pronounced in the SWC (R (super 2) =0.38; p<0.001). Regression lines for these data describe the local relationship between salinity and delta (super 18) O. The slope and intercept (freshwater end-member) derived for the SWC (0.15+ or -0.02ppm/psu; -4.56+ or -0.77ppm) are similar to those from Fairbanks et al. [1] for the Atlantic as a whole (0.19ppm/psu; -5.97ppm) and essentially identical to those from Legrande and Schmidt [2] for the "Tropical Atlantic" (0.15+ or -0.01ppm/psu; -4.61+ or -0.30ppm). Gulf of Panama samples share a similar slope (0.28+ or -0.01ppm/psu) with those studies (0.26ppm/psu [1]; 0.27+ or -0.01ppm/psu [2]) despite those studies representing huge areas in the Pacific. The delta (super 18) O of the freshwater end-member inferred from our samples is lower (-9.54+ or -0.44ppm) than Fairbanks et al. [1] and Legrande and Schmidt [2] (-8.77ppm and -8.88+ or -0.30ppm respectively), but not significantly. Our freshwater end-member for the SWC samples (2sigma ranges from -6.1 to -3.0ppm) agrees well with measured freshwater sources near Galeta in the Caribbean (-2.7 to -5.2ppm; [3]), but not the Gulf of Panama (our 2sigma ranges from -10.4 to -8.7ppm compared to -8.4 to -6.1ppm; [3]). These preliminary data show that nearshore waters share a similar relationship between salinity and delta (super 18) O as open ocean waters, which improves our ability to interpret seasonal delta (super 18) O profiles in the skeletons of coastal mollusks and corals. 1.

AN - 1542644835; 2014-047573 AB - The Main Ethiopian rift (MER) is the premier example of rifting that is actively extending a continent. A key target in understanding the transition from continental rifting to oceanic spreading are the Quaternary linear magmatic-tectonic belts that extend discontinuously along the rift north of 6 degrees N (Wonji Fault Belt and Silti-Debre Zeyit Fault Zone). However, uncertainties remain as to how these zones of focused magmatic intrusion initiate. Possible precursors to the rift floor Quaternary linear magmatic-tectonic belts are preserved in the central MER. Here, Pliocene linear magmatic chains adjacent to the rift on eastern and western plateaus share many of the same morphological features as the later rift-floor magmatic-tectonic belts, and allow for a temporal probe of mantle sources and magmatic plumbing systems of the evolving rift. The Pliocene Akaki belt is located along the western Ethiopian plateau margin adjacent to the rift-floor Quaternary Silti-Debre Zeyit Fault Zone. Magmas within the Akaki belt extend to some of the most primitive recorded in the rift (up to approximately 14% MgO), and follow an augite-dominated fractionation path that is consistent with crystal fractionation at deep crustal levels. This interpretation is supported by geophysical evidence of melt present in the lower crust in this region. The magmatic plumbing system of the Akaki magmas is inferred to be similar to that of the adjacent Silti-Debre Zeyit Fault Zone. Both magmatic belts are dominated by fractionation at deep levels within the crust, and have abundant megacrysts of augite, feldspar and olivine--evidence of magma stalling. By comparison, lavas from the Wonji Fault Belt--the regionally dominant magmatic belt located adjacent to the eastern rift margin--have fractionated at much shallower levels and have few megacrysts. These data suggest a dominantly spatial control of the magma plumbing systems in the rift, with little temporal changes along the western rift margin during the Pliocene-Quaternary magmatic episodes. The trace element characteristics of more primitive (>7% MgO) Akaki lavas are comparable to other MER magmas, but show slightly elevated values of Ba/Rb and weakly negative K anomalies in primitive-mantle normalized plots. We interpret these characteristics as evidence for small quantities of amphibole in the mantle source of the Akaki lavas. By contrast, minor phlogopite is present in the source of adjacent Quaternary Silti-Debre Zeyit Fault Zone lavas, implying a temporal shift in mantle source lithologies of magmas along the western rift margin. The basis of this temporal shift and the origin of these contrasting source lithologies remains uncertain. While the geochemical signature of amphibole in the source of a magma indicates some contribution from the lithospheric mantle, the origin of this amphibole is equivocal and could be equally derived from modern or ancient metasomatic events. Easily fusible phases such as amphibole and phlogopite may be important in melt generation, and future isotopic characterization of the Akaki lavas will help constrain unresolved questions surrounding the origin of these phases and their role in magmatism in the central MER.

Their textures record the deformation and degassing magma underwent prior to quenching. Understanding the link between the final texture and the processes that created them requires experimental reproduction of volcanic conditions under constrained parameters. Technological advances at the X-ray tomography beamline at the Advanced Light Source, Lawrence Berkeley National Laboratory have now made it possible to visualize magma in 3D as it is being deformed at high temperature, which allows us to visualize and quantify the processes that form pyroclasts. We use a fast readout camera that allows tomography on a few minutes timescale in combination with a high temperature uni-axial apparatus transparent to tomography. We heated obsidian samples from Big Glass Mountain, California and andesitic glass from Pahoa, California at various temperatures up to 1400 K. After an initial foaming stage, the samples were subjected to pure shear flow at strain-rates varying between 10 (super -6) s (super -1) and 10 (super -2) s (super -1) . Magma rheology measurements in the past have typically been restricted to bulk measurements and visualization before and after the experiment. This limits the ability to interpret the measured relationship between stress and strain-rate and the evolution of texture. The in situ scanning allows us to track the deformation or relaxation of individual bubbles, development of strain localization, crack initiation and makes it possible to directly correlate these processes to the bulk measurements of stress and strain. These new measurements will improve the interpretation of the textures found within the products produced by volcanic eruptions.

A continuous evolutionary sequence exists between those objects that experienced only slight partial melting or sintering through objects that underwent prolonged melting episodes. In most cases, melting was accompanied by surface evaporative loss of magnesium and silicon. This loss resulted in outer margins that are very different in composition from the cores, so much so that in some cases, the mantles contain mineral assemblages that are petrologically incompatible with those in the cores. The precursor objects for these FoBs had a range of bulk compositions and must therefore have formed under varying conditions if they condensed from a solar composition gas. Five of the six objects show small degrees of mass-dependent oxygen isotopic fractionation in pyroxene, spinel, and olivine, consistent with the inferred melt evaporation, but there are no consistent differences among the three phases. Forsterite, spinel, and pyroxene are (super 16) O-rich with Delta (super 17) O approximately -24 ppm in all FoBs. Melilite and anorthite show a range of Delta (super 17) O from -17 ppm to -1 ppm.

Spinel in 3N-24 and spinel and Al-diopside in the FoB CAI are (super 16) O-rich (Delta (super 17) O approximately -23 + or - 2 ppm). 33E-1's UR oxides and Zr,Sc-rich Al,Ti-diopsides are (super 16) O-depleted (Delta (super 17) O approximately -2 ppm to -5 ppm) vs. Al,Ti-diopside of the FTA CAI and spinel (Delta (super 17) O approximately -23 + or - 2 ppm), and Wark-Lovering rim Al,Ti-diopside (Delta (super 17) O approximately -7 ppm to -19 ppm). We infer that the inclusions experienced multistage formation in nebular regions with different oxygen-isotope compositions. 3N-24 and 33E-1's precursors formed by evaporation/condensation above 1600 degrees C. 3N and 33E's precursors formed by condensation and melting (3N only) at significantly lower temperatures. 3N-24 and 3N's precursors aggregated into a compound object and experienced partial melting and thermal annealing. 33E-1 and 33E avoided melting prior to and after aggregation. They acquired Wark-Lovering and common forsterite-rich accretionary rims, probably by condensation, followed by thermal annealing. We suggest 3N-24 and 33E-1 originated in a (super 16) O-rich gaseous reservoir and subsequently experienced isotope exchange in a (super 16) O-poor gaseous reservoir. Mechanism and timing of oxygen-isotope exchange remain unclear.

This understanding focuses less on habitat reconstructions at specific sites than on the regional trends, tempo, and amplitudes of climate and habitat change. Sole reliance on any one indicator, such as windblown dust or lake sediments, gives a bias toward strong aridity or high moisture as the driving force behind early human evolution. A synthesis of geological data instead offers a new paleoenvironmental framework in which alternating intervals of high and low climate variability provided the dynamic context in which East African Horny evolved. The Oldowan behavioral record presents further clues about how early Homo and Homo erectus responded to East African environmental change. Shifting conditions of natural selection, which were triggered by climatic variability, helped shape the adaptability of Oldowan hominins. Together, the behavioral and environmental evidence indicates the initial adaptive foundation for the dispersal of H. erectus and the persistence of Homo. In particular, overall dietary expansion made possible by the making and transport of stone tools compensated for increased locomotor and foraging costs and provided effective behavioral-ecological responses to resource instability during the early evolution of Homo.

Terrains rich in low albedo dark material (DM) have been identified using Dawn Framing Camera (FC) 0.75 ?m filter images in several geologic settings: associated with impact craters (in the ejecta blanket material and/or on the crater walls and rims); as flow-like deposits or rays commonly associated with topographic highs; and as dark spots (likely secondary impacts) nearby impact craters. This DM could be a relic of ancient volcanic activity or exogenic in origin. We report that the majority of the spectra of DM are similar to carbonaceous chondrite meteorites mixed with materials indigenous to Vesta. Using high-resolution seven color images we compared DM color properties (albedo, band depth) with laboratory measurements of possible analog materials. Band depth and albedo of DM are identical to those of carbonaceous chondrite xenolith-rich howardite Mt. Pratt (PRA) 04401. Laboratory mixtures of Murchison CM2 carbonaceous chondrite and basaltic eucrite Millbillillie also show band depth and albedo affinity to DM. Modeling of carbonaceous chondrite abundance in DM (1-6 vol.%) is consistent with howardite meteorites. We find no evidence for large-scale volcanism (exposed dikes/pyroclastic falls) as the source of DM. Our modeling efforts using impact crater scaling laws and numerical models of ejecta reaccretion suggest the delivery and emplacement of this DM on Vesta during the formation of the approximately 400 km Veneneia basin by a low-velocity (<2 km/s) carbonaceous impactor. This discovery is important because it strengthens the long-held idea that primitive bodies are the source of carbon and probably volatiles in the early Solar System.

Martian dust devils have been identified both in images taken at the surface and in remote sensing observations from orbiting spacecraft. Observations from landing craft and orbiting instruments have allowed the dust devil translational forward motion (ground velocity) to be calculated, but it is unclear how these velocities relate to the local ambient wind conditions, for (i) only model wind speeds are generally available for Mars, and (ii) on Earth only anecdotal evidence exists that compares dust devil ground velocity with ambient wind velocity. If dust devil ground velocity can be reliably correlated to the ambient wind regime, observations of dust devils could provide a proxy for wind speed and direction measurements on Mars. Hence, dust devil ground velocities could be used to probe the circulation of the martian boundary layer and help constrain climate models or assess the safety of future landing sites. We present results from a field study of terrestrial dust devils performed in the southwest USA in which we measured dust devil horizontal velocity as a function of ambient wind velocity. We acquired stereo images of more than a 100 active dust devils and recorded multiple size and position measurements for each dust devil. We used these data to calculate dust devil translational velocity. The dust devils were within a study area bounded by 10 m high meteorology towers such that dust devil speed and direction could be correlated with the local ambient wind speed and direction measurements. Daily (10:00-16:00 local time) and 2-h averaged dust devil ground speeds correlate well with ambient wind speeds averaged over the same period. Unsurprisingly, individual measurements of dust devil ground speed match instantaneous measurements of ambient wind speed more poorly; a 20-min smoothing window applied to the ambient wind speed data improves the correlation. In general, dust devils travel 10-20% faster than ambient wind speed measured at 10 m height, suggesting that their ground speeds are representative of the boundary layer winds a few tens of meters above ground level. Dust devil ground motion direction closely matches the measured ambient wind direction. The link between ambient winds and dust devil ground velocity demonstrated here suggests that a similar one should apply on Mars. Determining the details of the martian relationship between dust devil ground velocity and ambient wind velocity might require new in situ or modelling studies but, if completed successfully, would provide a quantitative means of measuring wind velocities on Mars that would otherwise be impossible to obtain.

Generally, the CGM from Maine are hosted by pegmatites characterized by a LCT (Li-Cs-Ta) geochemical signature and are infrequent in pegmatites with NYF (Nb-Y-F) characteristics (e.g., Topsham area of the Brunswick pegmatite field). Significant chemical-compositional and structural differences are observed between the CGM from the Brunswick and Oxford pegmatite fields. Columbite-group minerals from the Brunswick pegmatite field mainly consist of columbite-(Fe), commonly with elevated Ti and Mg contents. By comparison, pegmatites from the Oxford field carry columbite-(Fe), columbite-(Mn) and tantalite-(Mn) with low Ti and Mg contents. The structural state of CGM from the Brunswick pegmatite field ranges from highly cation-disordered to cation-ordered, in contrast to predominantly highly ordered CGM in the Oxford pegmatite field. Limited concurrent fractionation of Mn from Fe and Ta from Nb observed in the Brunswick pegmatite field is characteristic of F-poor environments in general, and of F-enriched pegmatites with high mu HF/mu alkF (stability field of topaz). However, the extensive Fe-Mn fractionation preceding moderate to strong enrichment in Ta is typical of the Oxford pegmatite field, and apparently promoted by lepidolite-generating environments with prominent chemical potential of alkali fluorides and low mu HF/mu alkF. This observation finds support in data on CGM from numerous other pegmatite populations worldwide. In contrast, the structural state of CGM does not seem to be linked to the activity of different forms of fluorine. The overall abundance, diversity and temporal extent of the volatile components were undoubtedly different in the two pegmatite fields under study, and were apparently enhanced in the more fractionated pegmatites of the Oxford pegmatite field.

Given the importance of this discovery for the use of edible grain, further analyses have now been undertaken. Meticulous sampling combined with good preservation allow the authors to demonstrate that the Ohalo II stone was certainly used for the routine processing of wild cereals, wheat, barley and now oats among them, around 23 000 years ago.

The graben are partially to fully encircled by rings of contractional wrinkle ridges localized over the rims of the buried impact features to form systems of associated contractional and extensional landforms. Most of the buried craters and basins with graben identified to date are located in the extensive volcanic plains that cover much of Mercury's northern high latitudes. The distinctive relationship between wrinkle ridges and graben in buried craters and basins on Mercury is interpreted to be the result of a combination of extensional stresses from cooling and thermal contraction of thick lava flow units and compressional stresses from cooling and contraction of the planet's interior.

The origins of the historical specimens and the taxonomic history of the genus are reviewed. The plumages of C. anna are interpreted as highly sexually dimorphic (red males vs. greenish females); the juvenile plumage of males included brownish feathers that appear to have been retained and mixed with the incoming definitive plumage. The thigh musculature and pelvic and hindlimb osteology show that the strong legs and feet of Ciridops were probably used to move plant debris in search of insects. The closest living analog may be the Yellowhead (Mohoua ochrocephala) of New Zealand. Analysis of stomach contents of the single fluid-preserved specimen of C. anna disclosed remains of insects that are widely distributed in Hawaiian forest ecosystems. The traditionally claimed association of Ciridops anna with palms of the genus Pritchardia suggests that Ciridops may have fed in the accumulated debris in the axils of palm leaves. The patchy distribution of fossils of Ciridops may result from the birds being associated with nearly pure stands of Pritchardia that were in turn patchily distributed. Vulnerability of Pritchardia to introduced seed predators, including rats and humans, and to destruction of lowland habitats by cutting and burning, may have caused the prehistoric extinction of Ciridops on all islands except Hawaii.

Focused learning from mothers and other group members is critical in monkeys, with behaviours such as co-feeding playing strong roles in determining postweaning survival. While adult lemurs are capable of social learning, it is unknown how social information is incorporated during the development of feeding or what social learning strategies are used in this process. Here we evaluate the use of social learning behaviours and the potential for social learning in young ringtailed lemurs, Lemur catta, at the Beza Mahafaly Special Reserve, Madagascar. We show that infant and juvenile ringtailed lemurs use basic and generalized stimulus enhancement that occurs through behavioural synchrony with older nearest neighbours. More focused co-feeding occurred at low levels, and many of the social learning behaviours observed in the other social primate taxa were absent. High levels of individual exploration also contributed to learning, evidenced through high dietary diversity in juveniles relative to other group members. Our observations are consistent with the idea that simple social learning rules are responsible for the development of ecological complexity in many generalist vertebrate species, and that more complicated learning behaviours may not be necessary to learn complex and varied diets.

Yet, population genetic studies often reveal low levels of genetic structure across large geographic areas. On the other side, more direct approaches such as mark-recapture provide evidence of localized dispersal. To what extent can direct and indirect studies of marine dispersal be reconciled? One approach consists in applying genetic methods that have been validated with direct estimates of dispersal. Here, we use such an approach-genetic isolation by distance between individuals in continuous populations-to estimate the spatial scale of dispersal in five species of coral reef fish presenting low levels of genetic structure across the Caribbean. Individuals were sampled continuously along a 220-km transect following the Mesoamerican Barrier Reef, population densities were estimated from surveys covering 17 200 m2 of reef, and samples were genotyped at a total of 58 microsatellite loci. A small but positive isolation-by-distance slope was observed in the five species, providing mean parent-offspring dispersal estimates ranging between 7 and 42 km (CI 1-113 km) and suggesting that there might be a correlation between minimum/maximum pelagic larval duration and dispersal in coral reef fishes. Coalescent-based simulations indicate that these results are robust to a variety of dispersal distributions and sampling designs. We conclude that low levels of genetic structure across large geographic areas are not necessarily indicative of extensive dispersal at ecological timescales.

The management expertise within PAs is a function of the training, support and depth of the staff tasked with protecting the resources and should be a significant factor determining the distribution of wildlife species. However, there are few measurable linkages between wildlife populations and management effectiveness. Here, we addressed whether the management expertise within a PA is an important covariate explaining the occupancy of large terrestrial mammals, and identify the attributes of mammal species that would be effective for comparative monitoring of management effectiveness within PAs of developing countries. Six PAs within giant panda region, south-west China. We used systematic camera-trapping as the primary field methodology to detect the presence of large mammals and used expert scoring to assess the management level of these PAs. Occupancy modelling and logistic regression were used to determine those mammal species with adequate detections to control for ecological covariates and to compare differences in management level between the sampled PAs. Thirty-eight mammal species were recorded with a total sampling effort of 16,521 camera-days at 722 sample sites. Among the 14 examined mammals, Takin (Budorcas taxicolor) was the most detected mammal (333 detections at 153 locations), whereas Asiatic black bear (Ursus thibetanus) was estimated with the highest occupancy rate ( psi = 0.49) and leopard cat (Prionailurus bengalensis) was estimated with the highest detection probability (P =0.55). The independently assessed estimate of management expertise was a significant positive predictor for the occupancy of 11 of the 14 mammal species. Our results suggest that there are measurable consequences for increasing PA patrolling and that standardized monitoring of large mammals is an adequate comparative measure of management effectiveness across diverse PAs that experience extensive poaching pressure.

In April 2009 a dense stand of Saccharum spontaneum in the Panama Canal Watershed burned as a result of an anthropogenic fire. Regrowth was monitored throughout the 2009 growing season and compared to a nearby unburned stand with a similar management history. Six months after the fire, live aboveground biomass and stem density were similar but flowering shoot densities were significantly higher in the burned stand. Aboveground dead biomass was significantly higher in the unburned stand, and bare soil remained below much of the burned stand. Viability of seeds produced in the burned stand was comparable to surrounding unburned populations. Germinants were also observed in the burned stand in October and November whereas no seedlings were found in the unburned stand. These results suggest that fire promotes the growth of Saccharum and may enhance its spread by stimulating new shoot growth, increasing flowering shoot density and thereby seed production, and creating available habitat for recruitment of new populations by removing litter. It also may delay flowering thus extending the reproductive period of the species in Panama. Appropriate measures, including increased funding for fire control and public education, to reduce the frequency of dry-season fires would likely help to manage the spread of this very aggressive invader in Panama.

Regional per capita meat and milk production corresponds, respectively, to about 13 and 8 % of developed countries indicators. Livestock performances in this region have decreased within the last 30 years. In fact, SSA, with a 12 % bovine extraction rate against a world average of 21 %, includes about 16 % of world cattle, only producing 6 and 2.6 % of global meat and milk, respectively. These low performances have economic and environmental consequences reflecting the necessity for upgrading livestock managing skills in the region. This effort includes various components such as sanitary prophylaxis, reproduction, nutrition, and in particular, substantial increase in livestock yield for human consumption. This will allow for an improved animal and pasture management and soil preservation, enhancing meat production and decreasing methane and nitrogen emissions from enteric fermentation and manure processing. These environmental gains due to increased livestock off-take rates can represent relevant credits in the global Environmental Carbon Market under the United Nations Framework Convention on Climate Change Kyoto protocol. These credits can be used for investments in livestock essential services and marketing facilities leading to improved productivity.

This behaviour could lead to directed dispersal into areas with lower densities of conspecific trees, where seed and seedling survival are higher, and could profoundly affect the spatial structure of plant communities. We tested this hypothesis with Central American agoutis and Astrocaryum standleyanum palm seeds on Barro Colorado Island, Panama. We radio-tracked seeds as they were cached and re-cached by agoutis, calculated the density of adult Astrocaryum trees surrounding each cache, and tested whether the observed number of trees around seed caches declined more than expected under random dispersal. Seedling establishment success was negatively dependent on seed density, and agoutis carried seeds towards locations with lower conspecific tree densities, thus facilitating the escape of seeds from natural enemies. This behaviour may be a widespread mechanism leading to highly effective seed dispersal by scatter-hoarding animals.

To investigate the influence of different types of mangrove habitats on the relative contribution of mangrove and seagrass food sources in fish diets, four mangrove habitats adjacent to seagrass beds were studied in Florida and Belize using gut-contents and stable-isotope analyses: mangrove fringe forests, basin mangrove, mangrove ponds and overwash mangrove islets. Carbon and nitrogen stable isotope compositions of 41 fish taxa and an array of potential primary (microphytobenthos, litter, seagrass leaves and their epiphytes, algae, plankton) and secondary (benthic invertebrates) prey were analyzed with SIAR mixing models to examine food source contributions in fish diets relative to habitat type. In all study sites, delta 13C values of mangrove prey were significantly depleted relative to those from seagrass beds, allowing stable isotopes to provide reliable insights about origins of fish food. Seagrass prey located near basin mangroves in the Indian River Lagoon (IRL, Florida) had more negative delta 13C signatures than seagrass prey adjacent to fringing mangroves of the Florida Keys, suggesting that seagrass from the IRL incorporated dissolved inorganic carbon from mangroves. Contributions of mangrove and seagrass prey to fish diets were influenced by type of mangrove habitat and fish residency status. Resident species significantly relied on mangrove prey, whereas only four transients foraged in mangroves. Most transient fishes occurring in basin and fringing mangroves actively foraged in nearby seagrass beds, thus reinforcing the limited role of mangroves as fish foraging habitat for transient species. However, a shift in fish diet was observed for transient species from mangrove ponds, in which they relied on mangrove prey. In overwash mangroves (Belize), the enriched carbon signatures of fishes and the generally higher contributions of seagrass prey to fish diets suggest that fishes derived most of their food from seagrass beds. This trend was particularly highlighted for juvenile reef fishes that shelter in mangroves but forage in nearby seagrass beds. These findings emphasize the importance of considering fish ecology (residency and life status) and type of mangrove habitat when assessing the contribution of mangrove prey to fish food webs in the western Atlantic region.

Interpretations using terrestrial analogs and process mechanics extend our perspective on fluvial geomorphology to another world and offer insight into their formative processes. At the landscape scale, the varied morphologies of Titan's fluvial networks imply a variety of mechanical controls, including structural influence, on channelized flows. At the reach scale, the various morphologies of individual fluvial features, implying a broad range of fluvial processes, suggest that (paleo-)flows did not occupy the entire observed width of the features. DISR images provide a spatially limited view of uplands dissected by valley networks, also likely formed by overland flows, which are not visible in lower-resolution SAR data. This high-resolution snapshot suggests that some fluvial features observed in SAR data may be river valleys rather than channels, and that uplands elsewhere on Titan may also have fine-scale fluvial dissection that is not resolved in SAR data. Radar-bright terrain with crenulated bright and dark bands is hypothesized here to be a signature of fine-scale fluvial dissection. Fluvial deposition is inferred to occur in braided channels, in (paleo)lake basins, and on SAR-dark plains, and DISR images at the surface indicate the presence of fluvial sediment. Flow sufficient to move sediment is inferred from observations and modeling of atmospheric processes, which support the inference from surface morphology of precipitation-fed fluvial processes. With material properties appropriate for Titan, terrestrial hydraulic equations are applicable to flow on Titan for fully turbulent flow and rough boundaries. For low-Reynolds-number flow over smooth boundaries, however, knowledge of fluid kinematic viscosity is necessary. Sediment movement and bed form development should occur at lower bed shear stress on Titan than on Earth. Scaling bedrock erosion, however, is hampered by uncertainties regarding Titan material properties. Overall, observations of Titan point to a world pervasively influenced by fluvial processes, for which appropriate terrestrial analogs and formulations may provide insight.

We assess how sensitive the cosmic-ray spectrum is to changes in the sunspot placement and magnetic field strength, the large-scale dipole magnetic field strength, the wind ram pressure, and the Sun's rotation period. Overall, our results confirm earlier work that suggested the Archean Earth would have experienced a greatly reduced cosmic-ray flux than is the case today. The cosmic-ray reduction for the early Sun is mainly due to the shorter solar rotation period and tighter winding of the Parker spiral, and to the different surface distribution of the more active solar magnetic field. These effects lead to a global reduction of the cosmic-ray flux at 1 AU by up to two orders of magnitude or more. Variations in the sunspot magnetic field have more effect on the flux than variations in the dipole field component. The wind ram pressure affects the cosmic-ray flux through its influence on the size of the heliosphere via the pressure balance with the ambient interstellar medium. Variations in the interstellar medium pressure experienced by the solar system in orbit through the Galaxy could lead to order of magnitude changes in the cosmic-ray flux at Earth on timescales of a few million years.

(Mammalia, Artiodactyla) from Lainyamok, Kenya AN - 1220564168; 2013-002160 AB - The middle Pleistocene fossil mammal assemblage from Lainyamok in the southern Kenya rift has previously been considered the oldest (330-392 ka) African mammal community consisting entirely of extant species, with the dominant bovid tentatively attributed to the southern African blesbok (Damaliscus cf. dorcas). We show that the blesbok-like fossils from Lainyamok belong to an extinct species, described here as Damaliscus hypsodon sp. nov. The D. hypsodon hypodigm includes the previously unnamed small alcelaphine material known from late Pleistocene sites elsewhere in Kenya and Tanzania. Its dental anatomy, together with an ecomorphological analysis of its postcrania, indicates that D. hypsodon grazed in open and arid grassland environments. Although Lainyamok is no longer represented entirely by extant species, the absence of species common earlier in the middle Pleistocene of East Africa suggests substantial faunal turnover between 500 and 400 ka. Damaliscus hypsodon persisted in East Africa until the end of the Pleistocene and its extinction can be attributed to a loss of arid grassland environments at the onset of the Holocene. The fossil evidence from southern Kenya suggests that the development of the taxonomically modern large mammal community was a long-term process characterized by the extinction of grazing specialists, with marked turnover occurring between approximately 500 and 400 ka and near the end of the Pleistocene.

Evidence concerning the origin, as well as the timing of the divergence of each subfamily and even genera of the Gypaetinae has been elusive. Compared with the Old World, the New World has an unexpectedly diverse and rich fossil component of Old World vultures. Here we describe a new accipitriform bird, Anchigyps voorhiesi gen. et sp. nov., from the Ash Hollow Formation (Upper Clarendonian, Late Miocene) of Nebraska. It represents a form close in morphology to the Old World vultures. Characteristics of its wing bones suggest it was less specialized for soaring than modern vultures. It was likely an opportunistic predator or scavenger having a grasping foot and a mandible morphologically similar to modern carrion-feeding birds. The new fossil reported here is intermediate in morphology between the bulk of accipitrids and the Old World gypaetine vultures, representing a basal lineage of Accipitridae trending towards the vulturine habit, and of its Late Miocene age suggests the divergence of true gypaetine vultures, may have occurred during or slightly before the Miocene.

Here we collected quantitative palynological data from a stratigraphic sequence in tropical South America to provide floristic and climatic insights into such tropical environments during the Early Cretaceous. Methods: We reconstructed the floristic composition of an Aptian-Albian tropical sequence from central Colombia using quantitative palynology (rarefied species richness and abundance) and used it to infer its predominant climatic conditions. Additionally, we compared our results with available quantitative data from three other sequences encompassing 70 floristic assemblages to determine latitudinal diversity patterns. Key results: Abundance of humidity indicators was higher than that of aridity indicators (61% vs. 10%). Additionally, we found an angiosperm latitudinal diversity gradient (LDG) for the Aptian, but not for the Albian, and an inverted LDG of the overall diversity for the Albian. Angiosperm species turnover during the Albian, however, was higher in humid tropics. Conclusions: There were humid climates in northwestern South America during the Aptian-Albian interval contrary to the widespread aridity expected for the tropical belt. The Albian inverted overall LDG is produced by a faster increase in per-sample angiosperm and pteridophyte diversity in temperate latitudes. However, humid tropical sequences had higher rates of floristic turnover suggesting a higher degree of morphological variation than in temperate regions.

Here we examine the age and depositional setting of the youngest stratigraphic unit in three sectors of the Eastern Cordillera: (i) the Santa Teresa Formation (western flank), (ii) the Usme Formation (southern central axis), and (iii) the Concentracion Formation (northeastern central axis). These units were deposited prior to the main Neogene deformation events. They represent the last preserved record of lowland conditions in the Eastern Cordillera, and they are coeval with a thick syn-orogenic deposition reported in the Llanos Basin and Magdalena Valley. Based on palynological data, we conclude that the upper Usme Formation was deposited during the Bartonian-earliest Rupelian? (Late Eocene-earliest Oligocene?); the Concentracion Formation was deposited during the Late Lutetian-Early Rupelian (Middle Eocene to Early Oligocene), and the upper Santa Teresa Formation was accumulated during the Burdigalian (Early Miocene). These ages, together with considerations on maximum post-depositional burial, provide important time differences for the age of initial uplift and exhumation along the axial zone and western foothills of the Eastern Cordillera. The switch from sediment accumulation to erosion in the southern axial zone of the Eastern Cordillera occurred during the Rupelian-Early Chattian (Oligocene, ca 30 to ca 26 Ma), and in the northeastern axial zone occurred prior to the latest Chattian-Aquitanian (latest Oligocene-Early Miocene ca 23 Ma). In contrast, in the western flank, the switch occurred during the Tortonian (Late Miocene, ca 10 Ma). In addition, we detected a marine transgression affecting the Usme and Concentracion formations during the Late Eocene; coeval marine transgression has been also documented in the Central Llanos Foothills and Llanos Basin, as evidenced by the similarity in floras, but not in the western foothills. Our dataset supports previous sedimentological, geochemical and thermochronological works, which indicated that (i) deformation in the Eastern Cordillera was a diachronous process, (ii) the sedimentation along the axial zone stopped first in the south and then in the north during the Oligocene, (iii) depositional systems of the axial zone and central Llanos Foothills kept partly connected at least until the Late Eocene, and (iv) Miocene strata were only recorded in adjacent foothills as well as the Magdalena and Llanos basins.

In La Canada area, strike-slip deformation is dominant and cuts former compressional structures; faults and folds of this area end northward abruptly near Rio Paez. To the north of Paez River is the La Hocha area that includes the Tesalia Syncline and La Hocha Anticline, two curved folds that plunge at the same latitude. The southern domain of La Hocha Anticline is asymmetric and bounded by faults in both flanks, whereas the symmetry of the northern domain is related to subsurface fault bending. Paleomagnetic components uncovered in Jurassic rocks suggest a clockwise rotation of 15.2 + or - 11.4 in the southern domain, and 31.7 + or - 14.4 in the northern domain. The Iquira Area, North of La Hocha, the internal structure is controlled by east-verging faults that end abruptly to the north of this area. The northernmost area is the Upar area that includes fault systems with opposite vergence; west-verging faults at the east of this area decapitate east-verging faults and folds. Paleomagnetic data, geologic mapping and regional structural cross-sections suggest that: (1) pre-existing basement structure controls the curved geometry of La Hocha Anticline; (2) along-strike changes in structural style between adjacent areas and along-strike termination of faults and folds are related to the location of northwest-striking transverse structures in the subsurface; and (3) at least two deformation phases are documented: an Eocene-Oligocene phase associated with the growth of folds along detachment levels within Mesozoic rocks; and a late Miocene phase associated with transpressive faulting along the Chusma and San Jacinto faults. The latter event drove clockwise rotation of the La Hocha Anticline. Abstract Copyright (2012) Elsevier, B.V.

Its delta position has changed several times over the Neogene. The Arroyo Piedras Section (169 m) in northern Colombia, contains part of the record of the Late Miocene to Early Pliocene evolution of the Magdalena paleodelta. The section was described and sampled for sedimentological and micropaleontological analyses. Based on lithofacies and benthic foraminifera content, the section was divided in three segments, and the upper segment was dated as Early Pliocene using planktonic foraminifera. The lower segment suggests siliciclastic sedimentation in a proximal prodelta/delta plain transitional environment. The intermediate segment suggests sedimentation in a lagoon and/or coastal swamp environment, whereas the upper segment is interpreted as the result of a transgression and subsequent deposition at the foreshore/upper shoreface environment, with a considerable decrease of terrigenous input. The decrease of sediment delivery to the delta produced by permanent El Nino-like conditions coupled with autocyclic processes could explain the transgressive pattern observed in the Arroyo de Piedras section during the Early Pliocene.

The lower to middle Paleocene units have similar thicknesses, and show a depositional profile varying northward from fluvial-estuarine environments to shallow marine carbonates. Sandstones show high quartz percentages (up to 80%) and detrital zircon age populations are dominantly older than 0.9 Ga (with peaks in 1.55 and 1.8 Ga), with minor populations in the range of 400-600 Ma. In contrast, the upper Paleocene units were deposited in marginal, coal-rich environments, and have strong variations in thickness among the four studied areas. These sandstones show quartz percentages between 40 and 70%, and have a significant increase in metamorphic fragments (approximately 13% of the total framework) as compared to the lower Paleocene sandstones (5-7% of metamorphic lithic fragments). The lower Eocene sandstones, on the other hand, show an increase in k-feldspars and quartz content. The detrital zircon age populations for the upper Paleocene and lower Eocene sandstones in the western sections show a strong decrease in ages from 1.3 to 2.5 Ga and an increase in ages from 55 to 360 Ma; in contrast, age populations older than 0.9 Ga persist in the southern section. The lower-middle Paleocene rocks suggest a regional, basin-wide drainage system fed by the Cretaceous sedimentary cover exposed in low-amplitude localized uplifts and developed a mixed siliciclastic-carbonatic platform in the shelf areas. On the other hand, the upper Paleocene-lower Eocene synorogenic succession accumulated in several basin compartments separated by more pronounced source areas and recorded the introduction of new ones. These sandstones contain basement rock fragments from marginal uplifts of the Santa Marta Massif and the Central Cordillera, as well as fragments from emerging intraplate ranges, such as the Perija Range and the Santander massif. Caribbean subduction along the northwestern margin of South America induced tectonic changes inside the Maracaibo Block, modifing sedimentary depocenters from a regional basin (ca. 300 km width) to isolated intermontane basins, which have been separated since the late Paleocene to present.

Cathodoluminescence is widely used in the study of sedimentary rocks and to a lesser degree, metamorphic and igneous rocks. The application of CL to the investigation of pegmatitic rocks has been meager, in part due to the limited number of pegmatite minerals for which distinct CL properties have been adequately determined. The use of CL in the examination of granitic pegmatites has been applied largely to studies of quartz, feldspar, apatite and zircon. However, the wide variety of minerals known to occur within granitic pegmatites makes them favorable candidates for much more extensive CL examination. A collection of 50 different pegmatite minerals from several localities were examined using a cold-cathode cathodoluminescence instrument in order to define characteristic features that can be used for general petrologic studies of granitic pegmatites. The minerals examined in this study include not only common rock-forming silicates (e.g., quartz, feldspar, muscovite), but also oxides containing high-field strength elements (e.g., columbite-group minerals, cassiterite), primary and secondary phosphates (e.g., apatite, montebrasite, lazulite), halides (e.g., fluorite, cryolite) and minerals hosting the light lithophile elements, Li, Be and B (e.g., spodumene, beryl, tourmaline). CL images were captured using a CCD camera and compiled to create an atlas which will serve as the primary resource for future CL studies of granitic pegmatites.

These have resulted in a marked increase in the number of globally correlatable speciation and extinction events, many of which have been integrated with chemo- and magnetostratigraphic records. The greatest refinements to Cretaceous chronostratigraphy have been achieved for the Campanian and Maastrichtian intervals with development of well-calibrated age-depth curves from multiple deep-sea sites, restudy of foraminiferal ranges in the classic magnetostratigraphy section at Gubbio, Italy, and orbital tuning of high-resolution carbon isotope records from a number of important pelagic chalk sections. New bioevents integrated with chemostratigraphic data have been documented from studies of exceptionally well-preserved foraminiferal assemblages from Cenomanian-Santonian boreholes drilled in coastal Tanzania, late Aptian-early Albian and late Albian assemblages from deep-sea boreholes on Blake Plateau (North Atlantic) and Falkland Plateau (South Atlantic), and early Aptian and Santonian-Campanian boundary assemblages from Shatsky Rise (North Pacific). Revisions to the taxonomy of the Cretaceous planktonic foraminifera are primarily being led by participants of the Mesozoic Planktonic Foraminiferal Working Group (see http://portal.chronos.org/gridsphere/gridsphere?cid=res_taxondb). Multi-disciplinary efforts to improve Cretaceous chronostratigraphy are being coordinated through the EarthTime EU initiative (see http://earthtime-eu.eu/earthtime/). Results from these and other community-based scientific efforts will lead to vast improvements to the accuracy and resolution of the standard Cretaceous geological time scale.

The Cenozoic interval as well as the latest Cretaceous (late Campanian-Maastrichtian) part of the benthic oxygen isotope curve is well-established and serves as a foundation for integrating various paleoenvironmental and geological observations with Earth's paleoclimatic evolution. By contrast, compilation of a benthic oxygen isotope record for much of the Cretaceous (from pre-late Campanian dating back to 115 Ma) has been hampered by a number of difficulties such as poor core recovery, relatively high levels of diagenetic alteration, presence of widespread unconformities at certain age-intervals, and/or restricted paleoceanographic conditions the Atlantic sites that have been most studied. To establish a better global paleoclimatic record through the Cretaceous, it is necessary that the available benthic oxygen isotope data are strengthened and extended further by additional high-quality data that are not influenced by local paleoceanographic effects. High quality samples from the central Pacific would be ideal for this purpose because of the central Pacific represents a fully open-ocean setting. However, technological, diagenetic and/or primary sedimentological issues mentioned above have long impeded data collection from this region. Situated in the central Pacific during the Cretaceous, Shatsky Rise is the only place where a pelagic sediment cover potentially dates back to the earliest Cretaceous. Recent IODP Expedition 324 (Sites U1348 and U1349) recovered some unique suites of Cretaceous pelagic carbonates that are unconsolidated (described as ooze) and yield generally well-preserved benthic foraminifera. The recovered sedimentary records are limited in stratigraphic extent, but they give important insights that allow for improvement of the Cretaceous deep-sea benthic oxygen isotopes record.

Although many discussions of Ediacaran-Cambrian events have focused on just one segment of this macroevolutionary triad, we argue for the importance of understanding the network of interactions among and within changes to the physical environment, ecology and development. Recent molecular clock evidence (Erwin, et al. 2011, Science) favors a divergence of sponge and cnidarian clade ancestors c. 780 Ma, followed by the origin of major bilaterian clades during the Ediacaran, and the origin of bilaterian crown groups close to the Cambrian boundary, consistent with evidence from the fossil record. These results suggest that the primary cause for the bilaterian diversification at the base of the Cambrian was either environmental or ecologic, building on a wealth of developmental tools that had evolved by the late Cryogenian or early Ediacaran. Theories for the cause of the Cambrian explosion differ strongly in the extent to which they follow currently operating mechanisms vs. invoking non-uniformitarian explanations, a dichotomy particularly apparent among geochemical workers, but subtly present among hypotheses involving ecology and development as well.

Recent efforts to develop an evolutionary classification of the biserial taxa have led to a radical revision of their species and genus level taxonomy. Foraminiferal assemblages from boreholes drilled as part of the Cretaceous Tanzania Drilling Program are ideal for testing proposed revisions to the Late Cretaceous biserial taxonomy and phylogeny because of the nearly continuous Cenomanian-Maastrichtian recovery and unusually good shell preservation. To investigate proposed species concepts and to clarify their identification, we have undertaken a quantitative approach to describing key characteristics of each species. In doing so we use SEM and X-ray images of well-preserved Cenomanian-Santonian biserial specimens, including Planoheterohelix moremani, Pl. postmoremani, Pl. globulosa, Pl. reussi, Protoheterohelix washitensis, Pr. obscura, Laeviheterohelix pulchra, Pseudotextularia nuttalli, Huberella praehuberi, and Hu. huberi. The study is based on over 200 specimens picked from Tanzania Drilling Program Site 31 as well as a few from IODP Site 463 and ODP Hole 1050C. In addition, new SEM images were taken of all available primary type specimens, enabling quantitative comparison with data collected from the core samples. The qualitative and quantitative observations to describe the Late Cretaceous biserial populations are not only useful for testing proposed taxonomic concepts, but also in helping to identify key features that allow for a clearer distinction between biserial species. This added resolution will help future bio- and chemostratigraphic studies.

Because of the clay-dominated lithologies and shallow burial depth, microfossil preservation is extraordinarily good through most of the drilled sequences, providing good age control and valuable insight to the climate and oceanography of the western subtropical Indian Ocean region. Multiple attempts to recover a continuous Cenomanian-Turonian boundary interval failed because of the presence of a loose sand bed that collapsed when drilled, causing the drill bit to get stuck and abandonment of the borehole. Absence of microfossils from the sand unit prevents its age determination, and no cores from the uppermost Cenomanian have thus far been obtained. Despite recovery of an unusually thick (75 m) sequence assigned to the planktonic foraminiferal Whiteinella archaeocretacea Zone, which has been estimated to span 0.54 m.y. according to the 2004 geologic time scale, bulk carbonate and organic carbon delta (super 13) C analyses do not show a shift that can be associated with Oceanic Anoxic Event 2 (OAE2). New data from single species oxygen and carbon isotopic analysis, with selection of two planktic and two benthic species per sample, detailed taxonomic analysis, planktic species abundance counts, and planktic:benthic ratios will be obtained to evaluate how much, if any, of the OAE2 interval was recovered during the Cretaceous TDP campaign.

Orogenic activity and climatic fluctuations have triggered major changes in the landscape by shaping the evolution of their biota during the Neogene. But, how these physical processes have affected plant species composition in neotropical forests? We studied the palynostratigraphy of three Neogene sequences from northern South America located in eastern Colombia and western Venezuela, in which savannas and xerophytic vegetation, respectively, dominate the landscape at present. These sequences reach 8 Km of thickness providing a detailed record of environmental change over the Neogene. One of the most striking findings from our fossil record is the presence of a wet forest over the Miocene instead of those biomes that characterize both areas now days. The expansion of neotropical savannas began in the Pliocene as recent phenomenon, that can be linked to a continuous reduction in rainforest areal coverage over the past five million years. The dynamic of the landscape is also reflected by two discrete and well-defined flooding events occurred in the early and middle Miocene stages. These events are associated to marine incursions and the presence of a large-scale fresh water already reported for the northwestern Amazonia.

Some studies suggest that its base ranges into the Cretaceous, whereas others indicate its top ranges to the Selandian. Given that surface sections of the Salamanca are often less than 50 meters in total thickness, this represents significant chronostratigraphic uncertainty. Understanding the age of the Salamanca is complicated further by the great distances over which it is exposed and its transgressive character, creating the possibility of significant diachroneity. We report a multidisciplinary geochronological study of the Salamanca Formation in the western part of the San Jorge Basin, near Sarmiento City, to further constrain its age and improve comparisons with other fossiliferous exposures farther to the east. New micropaleontological results from planktonic foraminifera, calcareous nannofossils, and dinoflagellates all indicate an early Danian age for the base of the Salamanca. This is further corroborated by a new 40Ar/39Ar age determination from a basalt flow that is reported to lie directly below the Salamanca. The Salamanca Formation is overlain by the Rio Chico Group, starting with the "Banco Negro Inferior" (BNI), a mature putatively widespread paleosol unit, and the Penas Coloradas Formation. New U/Pb ages for zircons from volcanic ash beds in the upper Penas Coloradas provide a minimum age for the top of the Salamanca Formation, an approximate age for "Carodnian" vertebrates from eastern exposures of the Penas Coloradas, and a minimum age for vertebrates from eastern exposures of the BNI at Punta Peligro. Paleomagnetic results indicate that the Salamanca is entirely normal polarity, with reversals occurring in the overlying Rio Chico units. Given the new micropaleontological and isotopic age constraints, we correlate the Salamanca Formation in the Sarmiento area to Chron C29n and/or C28n. The Banco Negro Inferior is also normal polarity in this area but may represent a younger normal Chron (e.g. C27n), given the likelihood of a hiatus or unconformity at this level. The BNI has been reported to have reverse polarity in areas farther to the east, suggesting it is at least partly time-transgressive.

This program is designed to store and analyze stratigraphic information in order to both generate publication-ready stratigraphic plots and facilitate quantitative stratigraphic analysis. The fundamental unit for a stratigraphic analysis is the description of an outcrop or core section. Often this stratigraphic information is plotted "manually" using vector graphics editors (e.g., Corel Draw, Illustrator). However, this information although store on a digital format, cannot be used readily for any quantitative analysis, and any quantitative examination of the stratigraphic data necessarily takes further steps. We decide to follow a different approach by developing a relation database using MySQL to store stratigraphic data. This database was designed to store the diverse characteristics recorded on a stratigraphic description (e.g. fossil content, lithology, number of samples collected in a specific interval, sedimentary structures and information from previous bioestratigraphic, geochronological and/or geochemical analysis, among many others). StratDataPlot reads the information from the database, and draws a stratigraphic column allowing the user to select one or multiple fields stored in the database. Additionally StratDataPlot includes quantitative analysis tools to enable the user to quantify stratigraphic information (e.g. grain size, sorting and rounding, proportion sand/shale). Lastly, since this program is written in a widely-used, open-source, high-level computer programming language "R graphics/statistics language", it is already loaded with many of the crucial features required to accomplish basic and complex tasks of statistical analysis (e.g., R language provide more than fifty spatial libraries that allow users to explore various Geostatistics and spatial analysis). This new tool allows a deeper exploration of the stratigraphic data collected in the field.

Cases of exceptional soft-tissue preservation, as in the Burgess Shale, offer unique insights into fossil morphology and diversity of the middle Cambrian. The Burgess Shale is best known for exquisitely preserved specimens; however, its preservation quality varies, presumably as a result of tissue decay. Naraoia is a Nektaspid arthropod first described from the Burgess Shale. It is an ideal experimental proxy for Burgess Shale preservation because of its easily defined characteristics and range of morphologies, which may represent different stages of decay. Using 203 specimens from the Smithsonian Institution National Museum of Natural History collections, we constructed a detailed decay series ranging from 1 (poor) to 10 (exceptional), then assessed the preservational state of each individual. We compared approximately 30 attributes of Naraoia to the decay series and, with confirmation from MDS ordination techniques, identified those that were highly dependent on the organism's level of decay, and thus strongly taphonomically biased. Strongly biased attributes, such as the presence of genal spines and the overall shape of the carapace, are variable due to decay, and must be considered carefully in species designation. Our analyses also identified a clear correlation between the quality of preservation and the orientation of the specimen in reference to the bedding plane. Oblique specimens were typically poorly preserved. Identifying taphonomic biases influencing Naraoia is essential for accurately describing its true morphological variation, as well as preservational processes influencing all organisms found within the Burgess Shale. Understanding taphonomic processes resulting in Burgess Shale-type preservation is vital for accurate interpretations of Cambrian fossils at the dawn of complex animal life.

Aquaculture was introduced to the Setiu estuarine-lagoonal system (SEL) in Terengganu, Malaysia in the mid-1970s. As fish farm densities increase and the mangroves are cleared, excess nutrients and fish waste are supplied to the water column and sediments below. In order for the aquaculture industry in Terengganu, Malaysia to be sustainable, there must be a limit to expansion. Analyses of foraminiferal assemblages, delta (super 13) C, delta (super 15) N, and C:N ratios, along with sedimentological analyses are used here to determine how aquaculture in the SEL affects benthic communities, sources of organic matter, and grain size and sediment composition. Three cores were collected beneath fish cage sites, two (SET11-S43 and SET11-S40) from the northern lagoon region and one (SET11-S9A) from the southern estuary region. Cores SET11-S43 and SET11-S40 contain both calcareous and agglutinated foraminifera, though calcareous are dominant. Ammonia aff. A. aoteana and Ammobaculites exiguus are the most abundant species in SET11-S43 and stained (live at the time of collection) specimens extend to 26 cm. Ammonia aff. A aoteana and Sagrinella lobata are most abundant in SET11-S40 with stained specimens extending to 18 cm. Core SET11-S9A contains only agglutinated foraminifera, with Ammobaculites exiguus, Miliammina fusca, and Trochammina amnicola as the most abundant species. Stained specimens extend to the bottom of the core (30 cm). The percent of carbon, nitrogen, and organic matter content (loss on ignition) increase through time throughout SET11-S43 and SET11-S40. Throughout SET11-S9A, these same measurements first increase through time but then decrease, probably corresponding to the abandonment of farm practices. Preliminary grain size analyses show patterns that mirror those of carbon, nitrogen, and organic matter content in all three cores. In summary, aquaculture has affected organic matter content and sediment characteristics in the SEL, and preliminary data indicate correlative variations of foraminiferal assemblages.

In contrast, strata between coal-bearing intervals are typified by calcic and vertic paleosols, incised landscapes, and redbeds that contain the remains of vegetation adapted to seasonal rainfall. These dryland floras, inferred to have grown on moisture-deficient soils, are not as well understood due to preservational bias. To clarify the paleoecology of vegetation in basinal lowlands during intervals of seasonal precipitation, plant remains were studied from the Lower Pennsylvanian Tynemouth Creek Formation of New Brunswick, Canada, which accumulated on a fluvial megafan adjacent to an elevated margin. The redbed-dominated succession exhibits features consistent with deposition under seasonal conditions, including evidence for episodic discharge due to monsoonal precipitation, degraded interfluves mantled by vertic paleosols, and scattered waterholes in fluvial tracts. By integrating sedimentologic and taphonomic observations with quantitative megafloral analyses in facies context, this research shows how plant communities were distributed in Early Pennsylvanian dryland settings. Gigantic cordaitalean trees dominated the dryland ecosystem, with dense, monotypic forests blanketing degraded, moisture-stressed interfluve surfaces. Medullosalean pteridosperms were centered on wetter parts of the landscape, particularly near shallow ponds and perennial lakes in interfluve hollows, and aside waterholes that remained in fluvial drainages during the dry season. Dense stands of calamiteans grew alongside fluvial channels, where they were buried by crevasse splay and levee deposits during monsoon floods. Lycopsids and ferns were exceedingly rare and occupied the wettest habitats. Taxa traditionally characterized as "upland" plants were a rare but relatively diverse component of the ecosystem. The presence of these unusual plants in the same beds as cordaitaleans and pteridosperms suggests that they were not washed in from "extrabasinal" communities, but lived together with other clades on basinal lowlands.

Two currently functional floating fish cage complexes, SET11-S43 and SET11-S40, in a lagoon close to an inlet (salinity in the 20s) have mixed agglutinated and calcareous assemblages with the majority of live foraminifera at these sites being calcareous species. At an abandoned fish cage complex, SET11-S9A, located in a low salinity (<5) estuarine setting, Miliammina fusca and Ammobaculites exiguus dominate entirely agglutinated assemblages. Side scan sonar data as well as grain-size analysis of surface sediment samples surrounding the fish cage complexes indicate that a muddy substrate extends up to 10s of meters from the cages with a surrounding sandier substrate typical of most of the Setiu Estuary/Lagoon system. The percent of carbon and nitrogen in sediment exhibit distributional patterns that correlate with the distribution of the fish cage mud. Greater abundance of carbon and nitrogen in sediment is found to the north of the active fish cage complexes, SET11-S43 and SET11-S40, than to the south. High carbon and nitrogen abundance also characterizes samples taken within the fish cage complexes at SET11-S43 and SET11-S9A but not at SET11-S40. These patterns are attributed to organic matter input from both fish farms and the surrounding mangrove forest, as well as tidal currents.

Facilitator efforts are divided between creation of products and implementation of programs with little attention to the sustainability of products or teacher networks. The AGI-ASU-NASA Triad program provided an opportunity for American Geosciences Institute (AGI) and Arizona State University (ASU) School of Earth and Space Exploration (SESE) to reconceptualize this balance of resources, programs, networks and sustainability. AGI's education program has existing text and web-based curricula, networks of teacher leaders across the nation and a web-based platform linked into the national geoscience community. ASU SESE is a hub of Earth and space scientists, collections, facilities, research and science-education resources. At ASU, researchers, collections specialists, technologists, engineers, education & outreach (E&O) and formal education specialists, undergraduate and graduate students and retired scientists were engaged in the iterative process of developing two years of teacher professional development. Starting by mapping our goals to our resources and connections, we crafted a teacher program that developed into a model for leveraging resources in our institution. Our program had three main elements: Content-rich weeklong workshops (summer), 5-day field excursion (summer) and follow-up workshops during the school year (fall and spring). Design elements included teaming up with E&O staff of major science programs on campus, integrating existing curriculum, engaging top researchers to give presentations from their public outreach repertoires, grouping teacher to strategically support within-district collaboration and mentorship, connecting teachers in sustainable programs, partnering with other programs to engage additional specialists and resources and crafting a field excursion based on SESE faculty, researchers and graduate students who were available and interested. These elements reflect small steps and manageable decisions that can be reproduced at other institutions to provide well rounded content-based PD for local educators while fostering sustainable connections with teachers in the university's local community.

Our previous studies documented a total inventory of approximately 537 kg of As in >19,000 metric tons of sediment and porewaters in Little Lake Jackson, Highlands County, Florida. This resulted from monosodium methylarsonate (MSMA) pesticide applications to golf courses and lawns in topographically higher areas of the watershed. Although MSMA percolates downward in soils of many areas, this lake was susceptible to As accumulation because surface waters as well as impervious clay and sand lenses in local soils directed pesticide leachates towards the lake. Total As content in lake sediments exceeded the consensus-based sedimentary concentration for probable toxicity effects in freshwater benthic fauna. Subsurface waters in shallow test wells reached 11 times the federal standard for As in drinking waters, potentially exposing local residential wells. Our subsequent studies document total As, As(III), As(V), DMA, AsB, and MMA content in fish, crustacean, and reptile tissues at various levels in food chains of two MSMA-contaminated lakes. Total As concentrations in blue tilapia were as high as 11.6 ppm in organs and 1.5 ppm in muscle tissue, which is comparable to total As values measured in tilapia from the Human Blackfoot Disease area of Taiwan, where As in well waters leads to necrosis and need for amputation in humans. Bluegills showed total As content as high as 10.8 ppm in organs and 1.3 ppm in muscle tissue. Local subsurface geology in the watersheds of these lakes apparently led to unexpectedly high accumulations of As that might pose risks for aquatic fauna, as well as for humans who consume the aquatic fauna.

In spite of this importance, relatively little work has been undertaken to understand whether concretionary assemblages reflect the original ecological patchiness that is observed in modern habitats or whether there were taphonomic controls acting to produce the "spotty" record found in these types of fossil concentrations. For this study, we examined the lithological, preservational, ecological, and taxonomic similarity between 79 concretions and their respective faunas collected from five different concretion-rich intervals in the Baculites compressus/B. cuneatus biozone ( approximately 73.5 Ma) in a silty-sandy lithofacies of the Pierre Shale at the Kremmling Paleontological Resource Area in Colorado. This investigation provides a comprehensive documentation of the ecological and taxonomic structure of shallow nearshore marine communities in the WIS during the Late Cretaceous. The lithology of the concretions, variation in the preservational mode of fossil specimens, taxonomic composition of samples, and the relative abundance of the different genera are interpreted to reflect paleoecological and taphonomic differences on the sea floor. We found that the lithology of the concretions and the preservational mode of most molluscan specimens found within and among concretions show little variation, which suggests similar taphonomic controls on the formation of fossiliferous concretions analyzed in this study. Furthermore, this assessment shows that there are significant differences in taxonomic composition, richness, and abundances among distinct concretions within and between concretion-rich intervals. Despite these differences, the dominance of small aragonitic and delicate fossil taxa (e.g., Drepanochilus, Anomia, Ostrea) suggests that these types of "spotty" concentrations more strongly reflect the original ecological patchiness that was found on the sea floor rather than the influence of taphonomic controls.

However, Mexican Hat, a southeastern Montana fossil plant site with a typical, low-diversity "disaster flora", anomalously exhibits remarkably high damage diversity compared to more than 100 other Paleocene sites. The site is part of the Lebo Member of the Fort Union Formation ( (super 40) Ar/ (super 39) Ar ages ca. 64.0-64.7 Ma). The flora is dominated by four species: Platanus raynoldsii, Juglandiphyllites glabra, Zizyphoides flabella, and Cercidiphyllum genetrix. To assess whether the high insect damage diversity at Mexican Hat could be attributed to survivorship of Cretaceous insects versus Paleocene immigrant or newly evolved taxa, we compared damage from Mexican Hat to that in the terminal Cretaceous Hell Creek flora in nearby, southwestern North Dakota. Thirty-one damage types (DTs) are found at Mexican Hat and represent four functional feeding groups (external feeding, piercing and sucking, mining, and galling). Preliminary results suggest that approximately 74% of the DTs observed at Mexican Hat span the K-Pg boundary, and approximately 26% first appear in the Paleocene. However, most of the persisting DTs are generalized forms made by various groups of insects and thus carry little information about species diversity or extinction. Host-specialized interactions, such as leaf mines, can be attributed to specific insect lineages in some cases. Seven of 10 specialized DTs at Mexican Hat, including 6 mine DTs, have not been found at Cretaceous or Paleocene sites, linking high damage diversity to an abundance of specialized interactions. We also compared damage on species of Platanaceae (sycamores), common in the Hell Creek flora, to diverse damage on P. raynoldsii. In this broader Platanaceae sample, damage unique to P. raynoldsii at Mexican Hat includes elliptical piercing and sucking marks, and larval mines from sawflies, microlepidopteran moths, and agromyzid flies. Overall, comparisons to Hell Creek insect damage more strongly supports the high damage diversity on the depauperate Mexican Hat flora as being caused by an influx of novel insect herbivores during the Paleocene, rather than survivorship of Cretaceous taxa from refugia.

Over 1,500 foliar elements from the Lower Permian (Kungurian) Colwell Creek Pond (CCP) site in Texas reveal low external foliage feeding levels but high incidences of piercing-and-sucking, oviposition, and galling. A diversity of galls were overwhelmingly represented on the peltasperm Auritifolia waggoneri. Leaves belonging to the form genus Taeniopteris suffered a high incidence and wide range of insect damage. The Gigantopteridaceae, an enigmatic seed-plant group, were represented by only one species, Evolsonia texana, which was not heavily herbivorized, in contrast to gigantopterid foliage in the two older, published floras from the same region. Incidences of new gall types add significantly to the late Paleozoic gall record and may shed light on the early transition from the Paleozoic to Modern insect fauna. In addition, there was significant presence of new scale-insect damage types on a variety of plant hosts. This unusually robust data set gains significance as part of the iconic Pennsylvanian-Permian terrestrial section of north-central Texas, which preserves an exceptional plant and animal record of this time period. Comparisons of the functional feeding groups represented at CCP with other sites within this section indicate that herbivory type and intensity were highly variable across habitat space during the late Paleozoic. Significantly higher incidences of insect damage occur at CCP than on Upper Permian foliage from Gondwanan South Africa, which is much better sampled than equatorial Pangaea. These qualitative and quantitative data shed light on changing plant-insect dynamics as lineages from the older late Paleozoic and the emerging Modern insect faunas coexisted until the end-Permian Extinction.

However, assessing the natural variation and systematic value of leaf size and shape (architecture) remains one of the most difficult challenges in botany and paleobotany. Living leaves show tremendous variation both among and within the hundreds of thousands of plant species, and a single leaf can have tens to hundreds of thousands of vein intersections and free endings. Here, we compiled a very large database of annotated, cleared, angiosperm leaves with over 7500 images from multiple sources. We used a biologically inspired computer-vision system, based on experimental knowledge of object perception in the mammalian visual cortex, to automatically classify images into Order, Family, and other natural categories. After training, the system generates a large dictionary of venation patterns, which corresponds to the most informative leaf-image regions and has great potential for novel systematic studies. Despite the fact that nearly all samples had typical imperfections such as rips, insect damage, and low image quality, the classifications were correct many times more often than chance level, and much more frequently than alternative approaches based on leaf shape alone (without using venation). Overall, the success of the approach suggests that leaves have tremendous phylogenetic signal, probably comparable to that of flowers, that is now much more accessible for study.

No rates of evolution have been calculated for morphological changes observed in freshwater mollusks of the East African Rift. This is unfortunate, because several mollusk groups occupying ancient rift lakes have diversified with an accompanying increase in morphological disparity. The monophyletic group of Bellamya gastropods from Lake Malawi, in which currently four species are considered taxonomically valid, is a good example. Molecular analyses arguably indicate that these extant species are very young, and the strong demographic and spatial expansion these analyses revealed suggests that the group is diversifying since Late Pleistocene (135-70 ka) lake level drops of Lake Malawi. We studied morphological evolution via semi-landmark analyses of 912 Bellamya specimens from a high-resolution sequence of 21 early to middle Holocene fossil assemblages and 283 modern specimens of the four extant species. These data were combined with shell height measurements and information on the number of whorls, as these features are considered diagnostically important in Bellamya. Principal component analysis indicated that the fossil shells are intermediate in the abovementioned features to two extant nominal species, but the fossils also occupy an area of morphospace that is not represented in the modern fauna. Clustering using normal mixture models suggests that the fossil specimens belong to a single evolutionary lineage. The evolution in this lineage is best fit by a model of evolutionary stasis, hence slower than anticipated. The obtained rate parameters for changes in the number of whorls and in shell shape, however, are still remarkably high compared to those obtained in rate simulations along randomly resolved phylogenies. Evolutionary divergence towards the extant descendants could have occurred since the middle Holocene if morphological evolution for these features would have proceeded at rates comparable to the paleontological ones calculated for the fossil time series. For shell height, the simulated phylogenetic rates coincided best with the paleontological rates if divergence started some 50 + or - 20 ka ago.

We measured stable carbon isotope ratios in bulk organic matter (delta (super 13) C (sub org) ) at four sections that span the PETM in the SE Bighorn Basin, WY and generated a composite carbon isotope record from n-alkanes (delta (super 13) C (sub n-alk) ). The n-alkane curve shows an abrupt, negative shift in delta (super 13) C values, an extended CIE body, and a relatively rapid recovery to more positive delta (super 13) C values. Despite recording the abrupt, negative carbon isotope shift, the delta (super 13) C (sub org) CIEs are smaller in magnitude and fail to sustain minimum excursion delta (super 13) C (sub org) values for the same stratigraphic thickness. We modeled predicted delta (super 13) C (sub org) curves by applying enrichment factors based on modern C (sub 3) plants (approx. as difference between delta (super 13) C (sub n-alk) and delta (super 13) C (sub total plant tissue) ) to the delta (super 13) C (sub n-alk) records. Anomaly values, the difference between measured and predicted delta (super 13) C (sub org) values, were calculated and compared to weight percent carbon and grain size. There is no correlation between anomaly values and grain size or weight percent carbon before or after the CIE. During the CIE, however, anomaly values are greatest at high grain size and low weight percent carbon. We hypothesize that the anomaly is a result of allochthonous fossil carbon mixing with autochthonous PETM carbon. The presence of shark teeth, dinoflagellates, and Cretaceous zircons all suggest the introduction of Mesozoic material. Changes in the autochthonous: allochthonous carbon ratio could explain fluctuations in the delta (super 13) C (sub org) records during the CIE. Before and after the CIE, the ratio of autochthonous: allochthonous carbon would be uncorrelated with isotopic composition because the delta (super 13) C values of Mesozoic and Cenozoic C (sub 3) plants would have been similar. During the PETM, however, the isotopic composition of autochthonous organic carbon decreased dramatically and autochthonous and allochthonous carbon pools became isotopically distinct. A higher proportion of autochthonous PETM carbon would lead to more (super 13) C-depleted delta (super 13) C (sub org) values. The negative correlation between weight percent carbon and anomaly values could represent greater autochthonous input at higher weight percent carbon.

Among decapods, the infraorder Brachyura ("true" crabs) is the most derived, and it is comprised of eight main sections or bauplans with only five known from extant representatives. The two oldest brachyuran sections, Dromiacea and Homoloida, are first known from the Early to Middle-Late Jurassic, while the other six (Torynommoida, Etyoida, Raninoida, Cyclodorippoida, Dakoticancroida, Eubrachyura) have their earliest records in the Cretaceous, depicting it as a time of large Brachyura morphological diversification. However, the phylogenetic relationships among ancestral bauplans; i.e. all but Eubrachyura, or "higher" crabs, remain unclear. While Mesozoic brachyurans are well known for high latitudes, occurrences in the equatorial Neotropics are scarcely known, resulting in significant biases when attempting to address their phylogenetic relationships. A new bauplan from the Cretaceous of Colombia displays a unique combination of morphological traits (e.g. pediform dentate mouthparts, fusiform carapace, broad sternum, and large eyes) that, if considered independently, may advocate for different phylogenetic relationships. As a result, inclusion of this "chimera" in a cladistic context deeply affects the topology of the Brachyura tree, collapsing all of the primitive sections into a major polytomy. Majority-rule consensus trees better resolve this polytomy, and place this bauplan as sister taxon to the clade containing all of the Cretaceous-originated sections. Furthermore, the morphological innovation of fusiform carapaces, previously recognized only in some fossil and all extant Raninoida, appears to have evolved independently at least twice among podotreme clades during the Cretaceous, probably triggered by similar ecological pressures or adaptations to a similar lifestyles. In addition, newly discovered raninoidans from the Early Cretaceous of northern South America pull back the oldest confirmed records into the Valanginian ( approximately 137 My), and indicate a higher early disparity than previously assumed. The new findings help us gaining a better understanding on the role of the Neotropics on the origin, evolution and diversity of primitive crabs throughout geological time.

Several studies have argued that important changes occurred in the hydrological cycle during the PETM, but results have been inconsistent, ranging from global increases in humidity to drier conditions. Here we report major drying during the body of the PETM using a paleosol record in the southeastern Bighorn Basin. Paleosol changes also suggest more prolonged climate change with transitions that both precede and follow the PETM. The CALMAG method (Nordt and Driese, 2010) and a morphologic soil index were used to establish a high resolution record of changes in mean annual precipitation (MAP) and soil moisture through a approximately 70 m interval of paleosols. Those changes are compared with relative changes in mean annual temperature determined from delta (super 18) O values of tooth enamel from the mammal Coryphodon. In addition, mean annual precipitation (MAP) was estimated using floras from three stratigraphic levels. Paleosols of latest Paleocene age are characterized by features indicating very wet conditions. A distinct shift to drier soils occurred just prior to the onset of the carbon isotope excursion (CIE) associated with the PETM. The observation that climate change directly preceded the CIE is consistent with some previous marine and continental studies. Up-section changes in the morphologic and geochemical properties of the paleosols show a progressive drying trend into the lower part of the PETM. Even drier conditions are indicated by calcareous paleosols in the upper part of the PETM body, when temperatures were warmest. Purple-red, non-calcareous paleosols appear during the recovery phase of the PETM and indicate wetter soils and higher MAP, although the purple-red paleosols are better drained than those just below the PETM onset. The purple-red paleosols continue for approximately 15 m above the recovery and indicate that wetter soil conditions persisted after the recovery. It is not clear whether changes in the paleosols that preceded and followed the PETM reflect global forcing factors like orbital cycles or release of carbon that lacks an isotopic label; however, such mechanisms would provide a unifying explanation for shifts seen in continental and marine environments.

AN - 1442374591; 2013-079432 AB - The calculated excavation depth of the huge (500-km diameter) Rheasilvia Basin is twice the likely thickness of the crust, so Vesta's mantle should be exposed. A chondritic precursor for Vesta would require a high abundance of olivine in the mantle, and some Vestan meteorites (diogenites) are composed of orthopyroxene plus olivine, confirming its presence. Spectrometers on the Dawn orbiting spacecraft have identified and mapped diogenites in the most deeply excavated portions of the floor of Rheasilvia, as uplifted materials in locations on the crater wall, and as a component of ejecta outside the crater. Orbital geochemical analyses indicate a lower abundance of iron within Rheasilvia, relative to the rest of Vesta, supporting the diogenite identification. However, only orthopyroxene spectral features have been observed; so far, olivine has eluded detection by Dawn instruments. Experiments indicate that the olivine 1-micron feature can be masked by orthopyroxene in harzburgite diogenites, which typically contain only 10-35% olivine, or it may have been diluted during impact mixing. If olivine is really absent, this may suggest emplacement of diogenite plutons near the crust-mantle boundary, or the formation of a depleted upper mantle. Geochemical properties of diogenites, however, are inconsistent with their formation as residues from partial melting. The occurrence of diogenite at approximately 20 km depth in areas of the crater 200 km apart may suggest a widespread, uniform layer of cumulate diogenite, supporting the hypothesis of an early magma ocean. Although this model is popular, geochemical evidence in diogenites indicates a more complex petrogenesis and may require crystallization of multiple magmas. The geologic context for diogenites on Vesta provided by Dawn is consistent with the properties of the meteorites themselves, but does not distinguish unambiguously between models for their formation.

Fairly common in Mesozoic and Cenozoic terrestrial records, VMBs have been exploited to recover otherwise rarely found small-bodied taxa (particularly Mesozoic mammals) as well as to estimate relative abundance and species richness in ancient vertebrate communities. Nevertheless, their taphonomic origins are poorly understood. The Campanian Judith River Formation (JRF) of Montana preserves abundant VMBs in well-documented facies contexts, thereby offering an ideal opportunity to study VMB taphonomy. Three VMBs from the JRF were processed using a newly developed automated sieving system that minimizes damage and maintains any potential associations. All bioclasts (vertebrate, invertebrate, plant) >0.5 mm were separated by hand picking under light microscopy, producing 17,569 vertebrate bioclasts from approximately 80 kg of matrix. Yields ranged from 182-333 specimens/kg (raw counts are inflated to some degree by breakage during recovery). Most fossils are unidentifiable fragments in the 1-3 mm size range, but more than 20% of recovered specimens are identifiable. This identifiable fraction is dominated by teeth, jaw fragments, vertebrae, fish scales, and scutes. Taphonomic attributes were recorded on a subset of recovered material that includes both identifiable and unidentifiable specimens. Rounded bioclasts are present in both mudstone- (pond/lake) and sandstone-hosted (fluvial) VMBs, but are more common in the latter (35% vs. 27%). Reflective polish is also developed in both settings, again more commonly in the fluvial VMB (21% vs. 10%), but regardless of facies context, all bones that exhibit polish also exhibit rounding. Taphonomic indications of predation/scavenging are rare but present in all sites, including minute bite marks and teeth/scales devoid of enamel/ganoine (consistent with gastric processing). Our analyses of VMBs in the JRF are ongoing but suggest that previous models are inadequate to explain their origins. Only with a firm understanding of VMB origins can any biases be formally assessed, thereby permitting analytical comparisons of paleoecological signals.

The formation consists of three carbonate dominated units, each separated by thin (up to 15 m), black, laminated shales and siltstones. The siliciclastic units are thought to mark lowstand systems tracts (LST) representing fourth or fifth order regressive intervals within a third-order transgressive sequence responsible for deposition of the Smackover and overlying Haynesville package. Here we report on the first palynological assemblages to be described from the Smackover Formation. They were collected from four sampled intervals of the shale ("Shale C") separating the two lower Smackover carbonates, derived from cores drilled in the Little Cedar Creek Field (T4N, R13E, Conecuh County, Alabama). Samples from the lower shale (late HST) are dominated by an impoverished dinoflagellate flora consisting primarily of Pareodinia ?ceratophora and Gonyaulacysta spp., but also containing abundant Classopollis (from the extinct xerophilous conifer family Cheirolepidiaceae), bisaccate pollen grains and diverse spores. Dominance of Classopollis in this unit could represent strand vegetation, or conversely, dominant trees of the more arid interior ("Neves" effect). Samples from the upper unit are dominated by bisaccate pollen (?stem Pinaceae, ?Podocarpaceae) and Araucariaceae, and also include Classopollis. Spores include representatives of bryophytes, club-mosses and at least seven to eight fern families, and probable fresh water algal cysts. Pollen morphospecies reflect the cosmopolitan nature of Late Jurassic floras, but a significant percentage of spore species lack exact matches elsewhere, suggesting some degree of endemism. Spores are relatively abundant and diverse, suggesting paleoclimate could be more humid relative to evaporite dominated basins in the western Gulf Coast, and supporting an imputed plate position for the Conecuh embayment below 30 degrees north latitude. The Late Jurassic transgressional event in the Gulf of Mexico is apparently related to post-rift tectonic cooling and subsidence; however, the presence of higher order regressional fluctuations within this sequence suggests a more complex history whose cause remains uncertain.

The cores were sampled at 10 cm intervals to investigate whether the effects of hurricanes on foraminiferal assemblages are preserved over a time-scale (ca. 200 years) that would allow the history of hurricane strikes to be determined. At 59m water depth Epistominella vitrea dominates assemblages, averaging 77% of each sample, and is accompanied by Buliminella morgani and Nonionella opima. At 75m water depth Epistominella vitrea still dominates but is less abundant, averaging 61%: Uvigerina peregrina and Bolivina lowmani are more abundant at this depth. At 87m water depth assemblages have higher diversity with increased abundance of, for example, Bolivina barbata and Bulimina marginata: Epistominella vitrea is still the most common species, averaging 31% of assemblages. At 473m water depth Bolivina simplex, Islandiella norcrossi australis, and Cassidulina neocarinata are the most abundant species. Each assemblage was compared to known assemblages of hurricane units (determined in box cores) deposited by Hurricanes Ivan, Katrina and Rita. Hurricane units have low densities of foraminifera and increased relative abundances of Textularia earlandi and Ammonia tepida. No samples in the kasten cores yielded assemblages comparable to those of known hurricane units, suggesting that the foraminiferal signatures of hurricanes are lost to bioturbation and/or to dilution by in situ test input. Even so, environmental change is recorded in the cores. For example, cores from 75m and 87m water depth show increasing abundances of Epistominella vitrea, Buliminella morgani, and Nonionella spp. up-core. These species are associated with hypoxia and the cores thus suggest an increase in hypoxic conditions over the past ca. 200 years.

Various possible ancestral forms have been proposed but careful dissection of the early ontogenetic stages shows a close relationship with Clavigerinella. The evolutionary transition between Clavigerinella and Hantkenina has now been described from sections in Tanzania, Austria, Spain, and Italy. Here we review the Clavigerinella-Hantkenina transition in Tanzania using 145 specimens from 23 stratigraphic intervals in a single core and show how it encompasses several morphological varieties that we assign variously to Clavigerinella caucasica, Hantkenina singanoae, and Hantkenina mexicana. We discuss the morphogenetic constraints involved in the evolutionary transition and propose an ecological/adaptive model for the selective pressures involved in the evolution of tubulospines. The first occurrence of Hantkenina has traditionally been associated with the base of the Lutetian stage and the base of the middle Eocene.

The stratigraphic ranges of all planktonic foraminiferal index taxa in the lower middle Eocene are reviewed.

However, even in the absence of concrete phylogenetic affinity, numerical paleoecological approaches can be effectively used to make inferences about organismal biology, the nature of biotic interactions, and life history. One aspect of the Ediacara biota that has not yet received much attention is in-depth analysis of their population structure. The Mistaken Point Ecological Reserve in Newfoundland, Canada contains the oldest Ediacaran communities (579 approximately 560 Ma), with thousands of fossils preserved in situ on the upper surfaces of large, decameter-scale bedding planes. These organisms were originally soft-bodied and have been exceptionally preserved by overlying volcanic ash in a pompeii-style death mask, representing census assemblages ideally suited for size-frequency distribution studies. We used data compiled by Clapham et al. (2003) focusing on three rangeomorph taxa (Fractofusus, Beothukis, Pectinofrons), and one non-rangeomorph taxon (Thectardis). We used univariate and multivariate Bayesian Information Criterion (BIC) in the statistical environment R to compare population structure models. Size-frequency histograms reveal positive (right) skewed unimodal distributions with large variance, with relatively few individuals in the smallest size classes, followed by a peak in the lower end of the distribution, and decreasing numbers in larger size classes. The best-supported population structure using BIC resolves communities of all studied Ediacaran taxa at Mistaken Point as single cohorts. That conclusion can be explained by one (or more) the following hypotheses: 1) all populations represent single age-classes, indicating a single highly synchronous reproductive event; 2) the Ediacaran organisms possessed slow growth rates relative to rates of reproduction and/or recruitment thus size-frequency distributions appear continuous; 3) the studied organisms reproduced aseasonally (=continuously), so that size modes are absent. Numerical paleoecological studies offer an innovative means of evaluating population structure in extinct organisms, and ultimately may provide an alternative means of inferring phylogenetic affinities in enigmatic groups.

However, new studies of Panama's volcanic and tectonic history suggest that the isthmus rose several Ma earlier than previous estimates. This calls into question our understanding of the "Panama Hypothesis" under which decreased flow between the Pacific and Atlantic during closure of the CAS from 13-2.6 Ma led to stronger thermohaline circulation, the production of North Atlantic Deep Water, and increased North Atlantic temperatures, evaporation, and precipitation at high latitudes, thus resulting in Northern Hemisphere glaciation. Despite the potential significance of these connections, comparatively few paleoceanographic studies have directly examined the timing and climatic impacts of closure. Research on marine species divergence resulting from CAS closure has been ongoing since the '70s. These and other paleoceanographic studies suggest gradual shoaling over > or = 12 Ma caused a stepwise shutdown of deep, intermediate, and ultimately shallow water flow through the CAS. It is argued that these restrictions had considerable impacts on surface currents and global ocean circulation at depth, thereby influencing both regional and global climate; however, the exact linkages and timing are not well defined. The Nd isotopic composition of fish teeth from Pacific and Caribbean sediments act as sensitive recorders of local water masses and can be used to better constrain the timing and effects of closure. Notable changes in this isotopic signature have been documented in the Neogene Caribbean and interpreted as a record of CAS shoaling. In order to investigate earlier evidence of restricted flow through the seaway related to sill formation or pulsed exhumation events, the Nd isotope records from Ocean Drilling Program Sites 998 and 999 will be extended to 50 Ma. The acquired data will be combined with global climate and Nd models to determine teleconnections between this region and major global changes seen in the Neogene. Also, novel paleoceanographic proxies will be explored and the terrestrial and marine literature integrated to create a comprehensive history of the shoaling of the CAS and rise of the Isthmus of Panama.

Although crown metazoan marine bodyplans appear in the Cambrian, it is now apparent that many components of animal developmental genetic programs originated much earlier in the Ediacaran and Cryogenian, long before the appearance of the phenotypes with which they are now associated. The less familiar Ediacaran macrobiota is now believed to represent multiple independent higher-order clades, indicating that these groups may have possessed defining developmental strategies and molecular toolkits analagous/similar to metazoan bodyplans. To understand how the developmental process evolved during this time, as well as where these clades may fall within the tree of life, we have conducted a phylogenetically unconstrained evaluation of Ediacaran taxa to determine the minimum developmental toolkits required to build Ediacaran architectural elements. Organismal morphology provides both direct and indirect evidence for a wide array of developmental traits, and using a multidimensional developmental framework we have compared the developmental tools of select Ediacaran and modern taxa. Objectively measurable characters used for developmental categorization included body-patterning strategies such as presence/number of axes, axial (anteroposterior, dorsoventral) symmetry, morphological differentiation along axes, segmentation, or repetition of modular functional units; and ontogenetic parameters such as growth by addition of units (terminal or intercalary), growth by increase in size, or growth by fractal-like branching. These analyses suggest that an important change from Ediacaran to more metazoan-like development involved a transition from "2D" epithelial-style inductive development to a "3D" spatially-specified process. As Ediacaran preservation is as varied as it is exceptional, we have examined how taphonomic biases may have influenced our developmental analysis. Finally, this work also demonstrates the utility of first considering fundamental developmental strategies as a basis for constraining Ediacaran phylogenetic hypotheses.

The extraordinary preservation of these non-biomineralizing (or weakly biomineralizing) tissues is effectively a race between degradation and mineralization. These two processes are not independent, and can form feedback loops critical to the conservation of biological information. That is, degradation can create localized microenvironments favorable to a specific mode of authigenic mineralization, which in turn limits degradation and promotes preservation. The dependency of these processes, however, can be a double-edged taphonomic sword. If the degradation process is rapid or extensive and outpaces the authigenic mineralization process, biological information can be erased. Regardless of which authigenic mineral is involved, precipitation on degrading organic tissues (that serve as physical templates or chemically-preferred substrates) is the fundamental constructive process driving exceptional preservation. A compilation of case studies, including examples from the Ediacaran Gaojiashan, Doushantuo, Dengying, and Fermeuse biotas, the Cambrian Wheeler Shale, and laboratory-based taphonomic experiments, demonstrates how three taphonomic processes, kerogenization, pyritization, and aluminosilicification, are interrelated. Viewed in this light, the differing styles of burgess shale-type carbonaceous compression, ediacara-type death-mask preservation, and three-dimensional beecher's-type pyritization are instead components of a single taphonomic pathway, the end-members of which are defined by the nature, degree, and composition of authigenic minerals.

Because sexual dimorphism is a trait that occurs at the species level, recent studies, focusing primarily on modern birds, have used it to test the validity of species selection. Although results have varied, some have found a correlation between dimorphism and extinction risk or diversification rate. The fossil record makes it possible to explore this relationship in species for which we can determine actual, rather than projected, extinction rates. In this study we documented patterns of sexual dimorphism in Late Cretaceous ostracodes from the U.S. Gulf Coastal Plain, and tested whether the magnitude of sexual dimorphism relates to extinction or origination rates in these species. We obtained morphometric data from 33 species of ostracodes collected from sediment samples from the Late Cretaceous of Alabama and Mississippi. In order to accommodate their large sperm, male ostracodes are more elongate than females. We approximated the shape of ostracode valves as an ellipse and used the major and minor axes of this ellipse as measures of length and width. We modeled body size within each species as a mixture of two bivariate normal distributions, one each for males and females. We then used the Mahalanobis distance between the male and female distributions as a measure of sexual dimorphism. We determined that related species tend to have similar magnitudes of dimorphism, suggesting that this trait is phylogenetically conserved across these clades. Comparing stratigraphic ranges of highly dimorphic species to those with limited dimorphism indicated no systematic difference in extinction or origination rates with respect to dimorphism. In addition, we found no evidence of selectivity in origination or extinction with respect to body size or taxonomic family.

Previous studies suggest that the compositional variation of garnet in granitic pegmatites can provide information about the degree of pegmatite evolution and fractionation of the original magmatic melt. However, knowledge of the compositional variability of this mineral in granitic pegmatites, in particular in the important kind of rare-element (Li, Be, Ta, REEs) pegmatites, worldwide is still limited. Understanding the chemical variations of garnet in various pegmatites may help discriminate between Li-rich and Li-barren pegmatites, which can potentially be used as an exploration tool for this kind of deposit. In this study, we have done a comprehensive investigation of the major element composition of garnet in different kinds of pegmatites to determine the relationship between its chemical composition, the degree of pegmatite evolution, and the presence of Li mineralization. We have investigated Li-rich and Li-poor and LCT and NYF pegmatites, including pegmatites from the Borborema Pegmatite Province (Capoeira 2, Alto Mirador, Boqueirao, and Carrascao), northeastern Brazil, Eastern Brazilian Pegmatite Province (Golconda), Maryland (Ben Murphy), Maine (Lord Hill), Virginia (Rutherford # 2), New York (Baylis, Benson, Batchellerville, Greenfield), California (Little Three Mine), Pennsylvania (Avondale), New Mexico (San Miguel Co.), Poland (Szklary, Strzegom), and China (Guangdong). The new compositions obtained and those from previous studies indicate that garnet in most of the LCT pegmatites investigated has a higher spessartine component ( 2ppm). However, specimens older than approximately 3.5 Ma show delta (super 18) O ranges greater than those of modern specimens (> 1ppm), suggesting potential refugia where modest seasonal upwelling enhanced productivity. Baseline delta (super 18) O values were calculated for each shell based on geochemical data from deep-sea planktonic foraminifera. Profiles normalized to open-ocean marine conditions reveal the amount of upwelling and freshening experienced by the individual. This approach shows increasing freshening over the last 5 myr and almost no upwelling after 3.5 Ma. By 2.5 to 1.5 Ma, shells from the SWC recorded delta (super 18) O ranges and delta (super 18) O-delta (super 13) C correlations representative of modern oceanographic conditions at these localities, suggesting that nutrient-rich refugia were rare or absent by this time. This interval coincides with the delayed extinction which occurred 1 to 2 myr after final closure of the isthmus.

Our preliminary taxonomic results show that this assemblage is characterized by 47 species. These include microfossils, such fish otoliths (n = 821), and macrofossils, as represented by shark teeth (n = 257) and billfishes (n = 12). The billfishes are the most distinctive taxon in this assemblage, and are represented by vertebrae, rostra, and a nearly complete skeleton. The extraordinary preservation indicates that the site may be regarded as a concentration largestatten. The bathymetric ranges of related and extant species in this fossil assemblage indicate that it accumulated in between 100 m and 700m of water depth. Moreover, the relatively high abundance of the shark Isistius triangulus (a small pelagic organism that preyed on large fish and marine mammals) and bathypelagic to mesopelagic fishes which given its life habit needs nocturnal vertical migrations, suggest the presence of large fish shoals, shark schools, and that the fossil assemblage occurred in an oceanic upwelling system. Even though recent geological studies on the tectonic evolution of the Panamanian Isthmus indicate closure of the Central American Seaway around 15 Ma our study suggests the existence of a marine Caribbean-Pacific connection during the latest Miocene ( approximately 6Ma).

Unfortunately, given the scarce of knowledge from Neotropical fossil sites, current hypotheses about diversity dynamics during this migration event have been based on the paleobiological study of temperate (distal) sites. Here, we present a preliminary taxonomical report of several faunistic assemblages recently found in the Guajira Peninsula, northeastern Colombia). These faunas are of early-middle Miocene (17-15 Ma) and Latest Pliocene to early Pleistocene ( approximately 3-1.5 Ma) age. The combined mammal assemblage includes five orders (i.e., Xenarthra, Litopterna, Notoungulata, Astrapotheria and Rodentia) and ten families (i.e., Megatheridae, Nothrotheridae, Glyptodontidae, Pampatheriidae, Hydrochoeridae, Neoepiblemidae, Echymidae, Protherotheridae, Toxodontidae and Astrapotheridae), all with South American affinities. Additional fieldwork, with an increase in sampling effort will likely augment the taxonomical diversity of these sites. Due to its age and geographical location, the Guajira Peninsula is a critical window for characterizing the Neotropical mammal community through GABI's migrational intervals. We complement field data through analyzing the composition of late Neogene mammal communities in the Americas by computing the percentage of both native and migrational faunas across a latitudinal gradient, using the Paleobiology Database (www.paleodb.org). Our preliminary results suggest that migrations started in the late Miocene (10 Ma), but most exchange occurred after the early Pliocene ( approximately 5 Ma). In tropical South America migrants are recorded only after the middle Pleistocene. Although tropical data is scarce and have to be taken carefully, a similar pattern is observed in temperate South America. While there are some records of North American migrants in this region during the Miocene and Pliocene, it is not until the Pleistocene when migrants became common, representing 75% or more of the mammal fauna.

The older Las Cascadas Formation has produced a large mammal fauna indicative of the late Arikareean ( approximately 23-20 Ma) North American Land Mammal Age (NALMA). Small mammals identified from the Las Cascadas Formation include a bat possibly belonging to the extant Phyllostomidae and three rodents, the large petauristine flying squirrel Petauristodon, a smaller sciurid, and a small geomyoid similar to Texomys. A more diverse small mammal assemblage occurs in the Centenario fauna derived from the younger Cucaracha Formation. Radioisotopic dates and paleomagnetic stratigraphy constrain the age of the Centenario fauna to between 19.1 and 18.8 Ma (latest Arikareean NALMA). There are 10 species of small mammals in the Centenario fauna: a possible phyllostomid bat; the procyonid carnivore Bassaricyonoides and eight rodents, including two species of Petauristodon the small sciurid Nototamias two species of Proheteromys in the extant family Heteromyidae and three geomyoids in the extinct family Jimomyidae, Texomys stewarti and two larger undescribed taxa. A large bat from the Las Cascadas and Centenario faunas is similar to insectivorous bats in the Neotropical family Phyllostomidae. The oldest previously known member of this family is from the early Miocene of Argentina. Early Miocene phyllostomids in both North America and South America may represent an earlier unrecognized phase of the Great American Biotic Interchange. The occurrence of the related extinct family Speonycteridae in the Oligocene of Florida indicates a possible North American origin for this group. Most other small mammal genera from the early Miocene of Panama are also known from early to medial Miocene faunas in Florida and/or Texas, including the rodents Petauristodon and Texomys and the procyonid Bassaricyonoides. A tropical North American origin for these three genera is suggested by their older late Arikareean records from Panama. A mid-Cenozoic Mesoamerican mammalian fauna is corroborated by the presence of the camel Aguascalientia and the protoceratid Paratoceras in early to medial Miocene faunas in Panama, Mexico, and Texas.

Using femoral length as a proxy for overall body size in dinosaurs, we apply several statistical models to explore its evolution in a phylogenetic context. Targeted comparisons among models can be used to shed light on aspects of body-size evolution, and here we focus on two issues: (1) the pervasiveness of directional trends, and (2) the presence of detectable upper limits for body size. Directionality was assessed by comparing the fit of the non-directional model of Brownian motion (BM) to that of BM with an underlying trend. Results indicate support for a trend of increasing body size (Cope's rule) in some, but not all dinosaur clades. There is little indication that body-size trends vary systematically across time intervals, but they do vary substantially across dinosaur subclades. To assess the macroevolutionary evidence for an upper limit to dinosaur body size we compared the fit of the BM model to that of BM in the presence of an upper reflecting boundary, a scenario similar to Stanley's classic explanation of Cope's rule as a passive trend. This model was fit using a novel likelihood function, and its improvement in fit relative to BM was judged using a likelihood ratio test with the null distribution generated by simulation. Results support the existence of a macroevolutionary upper limit to body sizes in theropods, but not in sauropods or ornithopods.

AN - 1420508079; 2013-062892 AB - The uplift of the Panamanian isthmus had extensive biological, paleoceanographic and climatic implications. This event separated two oceans and joined two continents. A large body of research done more than a decade ago indicates that the isthmus uplifted around 3.5 ma ago. This dating has been used in wide variety of fields, from molecular biology to paleoceanography. Some have even proposed the rise of the isthmus to be the trigger of the onset of the arctic glaciation. Over the past four years, we have had the opportunity to access a vast amount of fresh rocks provided by expansion of the Panama Canal, a multibillion engineering endeavor, that has facilitated the exposure of rocks on a landscape otherwise covered by tropical rainforest. Terrestrial fossils, thermochronology, provenance, geochemistry and structural analysis indicate there are three major exhumation events, during the late Eocene ( approximately 38-4 Ma), the earliest Miocene ( approximately 20 Ma) and the late Miocene ( approximately 10 Ma). There is not evidence of a significant uplift 3.5 Ma ago. Provenance also indicates that by 10 Ma, the Panamanian block and South America were so close to each other, that exchange of sediments was already happening. In addition, neodinium modeling suggests that by the late Miocene ( approximately 10 Ma), the deep and intermediate water circulation from the Pacific into the Caribbean ceased, and only shallow waters (<200 m deep) could exchange across the isthmus. Fossil evidence and genetic analysis of a number of clades including snakes, crocodiles, bees, frogs, salamanders, some fresh-water fishes, and plants indicate that frequent migration of terrestrial elements across the isthmus started by 10 Ma ago. In contrast, mammal migration is very limited, and even by the late Pliocene ( approximately 1.7 Ma), there is no evidence of North American mammals having migrated into tropical lowlands of northern South America, suggesting than a barrier other than a physical connection did not allow a large scale exchange of mammals across the tropics. Shallow marine molluscan faunas indicated that a fully continuous terrestrial connection started by approximately 3.5 Ma as earlier research had proposed. The implications on this new geological model on regional and global paleoceanography and paleoclimatology still remain to be explored.

We present sedimentological, stratigraphic, geochronological, and geochemical data that suggest a relationship between the onset of El Valle volcanism, the volcaniclastic deposits of the Gatun Formation and the shallow marine deposits of the Chagres Formation. The significance of this relationship is that this young volcanism may have blocked the final--and shallow--Central American seaway in the late Pliocene. Composed by a thick sequence of approximately 500 meters of volcanoclastic marine sediments, the late Miocene Gatun Formation represents a shallow marine deltaic system draining into the proto-Caribbean sea during the late Miocene ( approximately 11-7 Ma). Four samples of felsic tuff of the middle Gatun Formation yield (super 238) U/ (super 206) Pb ages for magmatic zircons of 8.24+ or -0.15 Ma; and two samples give feldspar Ar/Ar plateau ages of approximately 9-9.8 Ma. These felsic volcanic rocks are likely the product of the earliest El Valle activity. U/Pb and Ar/Ar ages, U-Th/He thermochronology, trace element and isotopic geochemistry as well as sedimentological and stratigraphic field observations constrain a genetic relation between the Late Miocene north Panama Canal basin marine formations and the El Valle volcano. Massive Miocene volcanic activity was responsible for final closure of an important seaway that should have communicated the Caribbean and Pacific waters from about 10 Ma, up to about 4 Ma in central Panama.

We documented a type of thermal springs at the banks of a volcanic lake that are discharge zones of hydrothermal convection cells circulating groundwater within the near shore environment. The convection captures lake water through the lakebed, mixes it with deeper groundwater at velocities of 100s of m/d, then returns the water to the lake via the spring. The convection cell is flushed in a few hours and turns over the lake's volume in a few days. Most volcanic lakes and other relatively cool surface water bodies in areas of elevated geothermal heat fluxes meet the conditions for the occurrence of local hydrothermal circulation of groundwater. The type of spring we studied, the terrestrial version of black smokers, is likely present but perhaps unrecognized at many areas.

AN - 1420504900; 2013-062897 AB - The standard model of about 3 Ma for closure of the Isthmus of Panama is based on stratigraphic analyses of adjacent marine sediments, proxies for predicted changes in temperature, salinity, and productivity, trans-isthmian faunal differences and similarities, genetic patterns in living Isthmian faunas and the terrestrial vertebrate record (Jackson and Odea, this symposium). A new model proposes closure at 15 Ma calculated by using the Campanian to Eocene arc that stretches from Costa Rica to Colombia as a strain marker. The rotation and alignment of its component tectonic blocks is said to leave no space available for any oceanic connection after 15 Ma, but no evidence is provided in the model about emergence above sea level. Comparison of the two models shows a very similar geometry and chronology, differing mostly in the degree of submergence of the Central American Arc (CAA). We suggest that the scale, tectonic style, volcanism, oceanic setting, and biogeographic contrasts (the Wallace/Huxley/Lydekker Lines) of the Indonesian volcanic arc are similar to the Caribbean-Central American region, 15 million years ago, and explain why, despite proximity of the CAA to South America, final closure was delayed until 3 Ma. The contemporary boundaries of the Wallace/Huxley Lines are as narrow as 20 km during low sea-level stands between Bali and Lombok islands, and the Lydekker Line, demarcating the limit of Australian ground-dwelling land mammals, is as narrow as 40 km between Timor and Australia. Despite the narrowness of these gaps, deep Pacific Ocean water circulates into the Indian Ocean through several 1000-m-deep sills within the gaps. The net flow is about 10 million cubic meters per second (one/third the Gulf Stream in the Florida Straight), and establishes the deeper water-column composition throughout the region. There is too much error in paleogeographic reconstructions for the new model to rule out the presence of such 20 km-to-40 km gaps with deep sills between tectonic blocks. We suggest the Canal axis and the Darien-Choco gap provide Bali-Lombok (Wallace Line) analogues and the Choco-South America region a Lydekker Line analogue. This scenario also explains the continued marine connections and lack of intense terrestrial mixing between 15 and 3 Ma, as observed in the fossil record.

Recent geological surveys have provided new constraints on the timing of its uplift, suggesting the CAS shoaled far earlier than previously thought. Also increasing epsilon-Neodymium (epsilon (sub Nd) ) information measured on fossil teeth and debris from the Caribbean and tropical Pacific help hypothesize the history of water masses. Here we present the first fully coupled climate simulations that include the epsilon (sub Nd) transport and investigate the timing and oceanic impact of the Central American Seaway shoaling and closure. We show that a narrow strait is sufficient to affect inter-oceanic circulation and leads to a sluggish ocean meridional transport in the Atlantic. We suggest that a threshold between 200 and 500 meters determines the depth at which the sill dramatically impact the global ocean circulation. Despite limitations linked to model resolution, our results confirm and sharpen earlier interpretation of water masses flows through the seaway. Simulated epsilon (sub Nd) values in the Caribbean show that inputs from radiogenic Pacific intermediate waters in the Caribbean decrease when the seaway shoals. Compared to published data, they provide a first insight to constrain the Panamanian seaway uplift, and suggest a shoaling above 200 meters around 9 Ma at the latest.

A highly asymmetric correlation has been established here: a very well dated and studied event (onset of glaciation) has been correlated to a very poorly constrained one (geographic closure). Dating time of geographic closure is complex here because of the potential subtleties of shallow marine connections across an already tectonically closed Isthmus. However, new geologic data on both sides of the suture separating northwestern South America from the Isthmus, sheds light about timing of tectonic closure. We are developing three main arguments: 1) a space compatibility argument that consists in more accurately reconstructing the paleogeography of blocks so that we obtain the time when no space is available for deep marine connections; 2) a provenance argument, where the suture separates two mutually exclusive geochronological domains: the young Central American arc to the west from the old Andean terranes to the east; and 3) a paleomagnetic argument where vertical-axis rotations constrain the kinematic evolution of the tectonic blocks involved. We have found an uniquely Panamanian, 40-45 Ma (early Lutetian) detrital zircon fingerprint is present in middle Miocene strata of northwestern South America, but absent in underlying lower Miocene and Oligocene strata. We contend that this fingerprint represents the beginning of fluvial drainage exchange between the Panama block and South America, and therefore marks the time of docking and full seaway closure. Paleomagnetic data shows large vertical-axis rotations in most blocks involved in closure of the Isthmus, and help constrain gaps available for deep marine connections.

Recent studies reveal a dynamic ice age involving repeated discrete glaciations separated by periods of greatly diminished ice. How paleo-atmospheric CO (sub 2) varied during this period of dynamic climate, however, remains elusive. Here we present a cyclothem-scale reconstruction of Pennsylvanian (314 to 303 Ma) atmospheric CO (sub 2) contents developed through integration of stomatal indices (SI) of fossil cuticles and delta (super 13) C of soil-formed carbonates and associated or occluded organic matter. The SI record is based on two long-ranging taxa of wetland pteridosperms, Macroneuropteris scheuchzeri and Neuropteris ovata, from the Illinois Basin. Dryland taxa, Megalopteris and Lesleya, from two cameo intervals, provide constraints on the response of stomata to varying environmental conditions. The mineral-based proxy record was developed using pedogenic carbonates from the same set of Illinois Basin cyclothems and contemporaneous successions in the Appalachian and Donets basins. Recent correlation of the cyclothemic successions of the Midcontinent and Appalachian and Donets basins permits integration of the CO (sub 2) records and comparison to independent paleosol, geochemical, and stratigraphic proxies of climate and glacioeustasy. Similar SI trends are defined by M. scheuchzeri and N. ovata although variants of the latter exhibit offsets in SI. Intra- and inter-pinnule SI variation falls within the standard error of the mean for each leaf. Temporal variation in stomatal morphology, trichome density, and cuticle delta (super 13) C further correlate to SI trends providing insight into the origin of the stomatal trends. Integration of the mineral-based CO (sub 2) estimates with the SI trends delineates repeated short-term variations in atmospheric pCO (sub 2) that agree well with recent independent estimates of glaciation and glacioeustasy. Both records suggest that widespread reduction in the areal extent of tropical wetland forests in the late Pennsylvanian and associated aridification may have been linked to a multi-million year increase in CO (sub 2) concentration through a substantial decrease in organic C sequestration at this time.

Although largely unrecognized in the planetary community, terrestrial inflated sheet flows also display morphologies that share many commonalities with lava plains on Mars. The McCartys lava flow field is among the youngest ( approximately 3000 yrs) basaltic flows in the continental United States. The southwest sections of the flow displays smooth, flat-topped plateaus with irregularly shaped pits and hummocky inter-plateau units that form a polygonal surface. Plateaus are typically elongate in map view, up to 20 m high and display lineations within the glassy crust. Lineated surfaces occasionally display small < 1 m diameter lava coils. Lineations are generally straight and parallel each other, sometimes for over 100 meters. The boundaries between plateaus and depressions are also lineated and tilted to angles sometimes approaching vertical. Plateau-parallel cracks, sometimes containing squeeze-ups, mark the boundary between tilted crust and plateau. Some plateau depressions display level floors with hummocky surfaces, while some are bowl shaped with floors covered in broken lava slabs. The lower walls of pits sometimes display lateral, sagged lava wedges. Infrequently, pit floors display the upper portion of a tumulus from an older flow. In some places the surface crust has been disrupted forming a slabby texture. Slabs are typically on the scale of a meter or less across and no less than 7-10 cm thick. The slabs preserve the lineated textures of the undisturbed plateau crust. It appears that this style of terrain represents the emplacement of an extensive sheet that experiences inflation episodes within preferred regions where lateral spreading of the sheet is inhibited, thereby forming plateaus. Rough surfaces represent inflation-related disruption of pahoehoe lava and not a'a lava. Depressions are often the result of non-inflation and can be clearly identified by lateral squeeze-outs along the pit walls that form when the rising crust exposes the still liquid core of the sheet.

Cosmogenic and radiocarbon methods both give an age of approximately 3000 yr for the McCartys flow (Laughlin et al., 1994). Flows that have undergone inflation sometimes have margins that display a 'terraced' topographic expression, with each successive level at approximately one-half the thickness of the flow section from which it emanates. At the McCartys lava flow, we investigated several terraced margins where two or three distinct elevation levels occur. We used Differential Global Positioning System (DGPS) data to obtain precision topographic profiles across terraced margins. Terraces are typically 0.4 to 0.6 of the thickness of the inflated flow section from which they originate; if a second terrace level is present, its surface level is similarly about half the thickness of the source terrace. We postulate that the terraces represent discreet outbreaks from the inflated flow. At only one location were we able to identify the specific source of a terrace outbreak; a vertical fracture in the primary flow margin became a 'local vent' for a terrace extending approximately 200 by 80 meters from the breakout. The source fracture is only approximately 30 cm wide; the terrace material attained a level that is quite consistent over the entire terrace. A basaltic toe emanating from the margin of the terrace has approximately the same height relationship to the terrace as the terrace to the main flow, but flow into the toe ceased before more than a single digitate flow was produced. Field observations of terraces provide important constraints for interpreting similar features on Mars as a result of inflation.

A lower topographic unit surrounds the inflation plateaus to give inflated flow fields a multi-level topographic profile. Previous field work at lava flows in New Mexico (McCartys, Carrizozo) and Idaho (Sunset, Cerro Grande) show similar topographic relationships between the inflation plateaus with measured heights of 8 to 15 m, surrounded by a lower unit, typically 1 to 5 m in relief. Differential Global Positioning System (DGPS) measurements were obtained on three different inflated lava flows in Oregon (Devils Garden, Jordan Craters) and Idaho (Carey) to see if these topographic relationships and dimensions of inflation plateaus are consistent with previously studied flow fields. The Devil's Garden is 20,000 year old basaltic lava flow (86 sq. km, 1.2 cubic km), southeast of Bend, Oregon. Jordan Craters is an olivine basalt flow, 4,000 to 9,000 years old (65 sq. km, 1.0 cubic km) in southeast Oregon on the Owyhee Plateau. The Carey flow is comprised of Hawaiite lava that emanated from a vent on the northern end of the Craters of the Moon National Monument in central Idaho and is estimated to be similar in age to the Sunset flow, 12,000 years old. An impressive series of inflation plateaus is present on the distal end of the Carey flow. Plateaus are particularly well expressed in a region about 4 by 4 km across along the centerline of the flow, where individual plateau sections are separated by rows of aligned lava-rise pits. DGPS measurements were obtained to capture the topographic relationship between the inflation plateaus and lower units, as well as, measure the topographic gradients of the plateau surfaces both along and perpendicular to the flow. Detailed topography of terrestrial inflated flows can be compared with possible inflated lava flows on Mars and the Moon.

This includes the use of tree rings and corals, though long-term (>500 yrs) reconstructions from these archives are relatively sparse in the literature and those which do exist show marked disagreement prior to the instrumental period. The skeletons of long-lived sclerosponges offer another opportunity to investigate oscillatory change. Here, a approximately 700 yr old sclerosponge specimen of C. nicholsoni from 133 m depth in Exuma Sound, Bahamas has been U/Th dated and micromilled at a resolution of approximately 2 samples per yr. The samples have been analyzed for stable C and O isotopes, as well as minor and trace element compositions in order to reconstruct oceanic temperature and salinity. The results depict clear trends, including the (super 13) C Suess Effect showing the input of light CO (sub 2) into the ocean from the burning of fossil fuel over the last 150 yrs. Further, the temperature reconstruction indicates a warming of approximately 2 degrees C over this same interval, comparable in amplitude and small-scale variability with published sclerosponge records from the Caribbean. The reconstructions from this specimen also reveal pronounced multi-decadal cyclicity, with paleo-salinity possessing a 20-30 yr periodicity, akin to the solar cycle, over the entirety of the record. From the mid-1700s to the 1990s, the dominant periodicity in the salinity switched to approximately 68 yrs, consistent with the Atlantic Multi-decadal Oscillation (AMO). High salinity is associated with warm phases of the AMO and vice versa, suggesting that SST and solar variability were communicated to the sclerosponge through changes in the source region of the Salinity Maximum Waters. This record validates previous studies that indicate transitions from inter- to multi-decadal periodicities in the 1700s and supports a natural origin for the AMO through the persistence of multi-decadal trends prior to the period of anthropogenic impact. The marked long-term and regional instabilities between this and other published records imply that modern changes may have significant impacts on these modes, emphasizing the need for continued collaboration between paleoclimate and modeling communities to improve future projections of Atlantic multi-decadal variability.

Moreover, BiSSE is unusual in being able to distinguish past selection at the individual level from selection at the clade level. Of these modes, the former results in high rates of state transition toward favored character states, and the latter in increased net diversification for lineages possessing favored character states. However, BiSSE assumes that intrinsic rates of speciation and extinction and relative fitness of different character states are time-invariant, assumptions that are known to be false. This shortcoming does not necessarily signify that BiSSE is useless, as the algorithm may or may not be robust to its assumptions being violated. What insights can we paleontologists share with neontologists whose study groups lack good fossil records? To address this, I simulate evolution of hypothetical clades featuring state-dependent diversification rates using more paleontologically realistic assumptions. In addition, I also compare speciation and extinction rates inferred from the fossil record of the conifers (Plantae: Coniferophyta) against those inferred by BiSSE using a conifer phylogeny developed from molecular data. Conifers are a good study group for this purpose, being a living group with a resolved phylogeny, an excellent fossil record, and a living diversity featuring both modern, diversifying clades (e.g. Pinaceae) as well as ancient, declining lineages (e.g. Araucariaceae). Preliminary results with simulated data suggest that BiSSE performs well for clades whose net diversification rates have been positive through their entire histories, but becomes unreliable and prone to detect non-existent selective effects in groups that have been declining in diversity for part of their history. Further analysis will be discussed at the meeting.

AN - 1221144146; 17372891 AB - As protected areas become more accessible via transportation networks, fragmentation, and encroachment from the borders, carnivores in these areas frequently decline. To counter these pressures, patrolling and active wildlife enforcement are widely accepted as fundamental conservation strategies. Using the case example of Khao Yai National Park (KYNP) and data from a camera trap survey, we modeled and evaluated the effectiveness of ranger stations in reducing human access and illegal activities, and in increasing prey and predator presence. This type of data and analysis is needed to monitor and evaluate enforcement effectiveness and develop adaptive management strategies. At KYNP, we used camera-trapping data as a proxy to evaluate whether or not a positive impact of ranger stations on wildlife distribution could outweigh edge effects from human disturbance. We assessed factors affecting the distribution of poachers and wildlife using Maxent. Our analysis was based on 217 camera trap locations (6260 trap nights) and suggests that ungulates and poachers persist nearby ranger stations. Rangers should increase patrolling efforts of border areas; however, increasing wildlife patrolling in inaccessible areas with mobile range units may be more effective than establishing more ranger stations along park boundaries.

This decoupling may strongly limit our ability to assess the importance of food web interactions on ecosystem processes. 3.To evaluate how consumer trophic diversity mediates predator effects on ecosystem functioning, we conducted a mesocosm experiment and a field study using an assemblage of invertebrates that naturally co-occur on North Atlantic coastal saltmarshes. We measured the indirect impact of predation on primary production and leaf decomposition as a result of prey communities composed of herbivores alone, detritivores alone or both prey in combination. 4.We find that primary consumers can influence ecosystem process rates not only within, but also across green and brown sub-webs. Moreover, by feeding on a functionally diverse consumer assemblage comprised of both herbivores and detritivores, generalist predators can diffuse consumer effects on decomposition, primary production and feedbacks between the two processes. 5.These results indicate that maintaining functional diversity among primary consumers can alter the consequences of traditional trophic cascades, and they emphasize the role of the detritus-based sub-web when seeking key biotic drivers of plant production. Clearly, traditional compartmentalization of empirical food webs can limit our ability to predict the influence of food web interactions on ecosystem functioning.

For sedentary shallow water species, there is an additional, marine barrier, 5000 km of uninterrupted deep-water stretch between the central and the eastern Pacific. This expanse of water, known as the 'Eastern Pacific Barrier', has been separating faunas of the two oceanic regions since the beginning of the Cenozoic. Species with larvae that cannot stay in the plankton for the time it takes to cross between the two sides have been evolving independently. That the eastern Pacific does not share species with the rest of the Pacific was obvious to naturalists two centuries ago (Darwin 1860). Yet, this rule has exceptions. A small minority of species are known to straddle the Eastern Pacific Barrier. One such exception is the scleractinian coral Porites lobata (Fig. ). This species is spread widely throughout the Indo-Pacific, where it is one of the major reef-builders, but it is also encountered in the eastern Pacific. Are eastern and central Pacific populations of this coral connected by gene flow? In this issue of Molecular Ecology, Baums et al. (2012) use microsatellite data to answer this question. They show that P. lobata populations in the eastern Pacific are cut off from genetic influx from the rest of the Pacific. Populations within each of the two oceanic regions are genetically connected (though those in the Hawaiian islands are also isolated). Significantly, the population in the Clipperton Atoll, the westernmost island in the eastern Pacific, genetically groups with populations from the central Pacific, suggesting that crossing the Eastern Pacific Barrier by P. lobata propagules does occasionally occur.

AN - 1112341017; 22704386 AB - A major challenge to retaining viability of frozen gametes and reproductive tissues is to understand and overcome species-specificities, especially because there is substantial diversity in cryobiological properties and requirements among cell types and tissues. Systematic studies can lead to successful post-thaw recovery, especially after determining: 1) membrane permeability to water and cryoprotectant, 2) cryoprotectant toxicity, 3) tolerance to osmotic changes, and 4) resistance to cooling and freezing temperatures. Although species-dependency ultimately dictates the ability of specific cells and tissues to survive freeze-thawing, there are commonalities between taxa that allow a protocol developed for one species to be useful information for another. This is the reason for performing comparative cryopreservation studies among diverse species. Our laboratory has compared cellular cryotolerance, especially in spermatozoa, in a diverse group of animals-from corals to elephants-for more than 30 yrs. Characterizing the biophysical traits of gametes and tissues is the most efficient way to develop successful storage and recovery protocols, but, such data are only available for a few laboratory, livestock, and fish species, with virtually all others (wild mammals, birds, reptiles, and amphibians) having gone unstudied. Nonetheless, when a rare animal unexpectedly dies, there is no time to understand the fundamentals of biophysics. In these emergencies, it is necessary to rely on experience and the best data from taxonomically-related species. Fortunately, there are some general similarities among most species, which, for example, allow adequate post-thaw viability. Regardless, there is a priority for more information on biophysical traits and freezing tolerance of distinctive biomaterials, especially for oocytes and gonadal tissues, and even for common, domesticated animals. Our colleague, Dr John Critser was a pioneer in cryobiology, earning that moniker because of his advocacy and devotion to understanding the differences (and similarities) among species to better store living genetic material.

We used delta 13C and delta 15N values measured from bone collagen of historic and recent gray wolves and their potential primary prey from Yellowstone National Park to gain insight into the trophic dynamics and nutrient conditions of historic and modern grasslands. The diet of reintroduced wolves closely parallels that of the historic population. We suggest that a significant shift in faunal delta 15N values over the past century reflects impacts of anthropogenic environmental changes on grassland ecosystems, including grazer-mediated shifts in grassland nitrogen cycle processes.

Pitted terrain is characterized by irregular rimless depressions found in and around several impact craters, with a distinct morphology not observed on other airless bodies. Similar terrain is associated with numerous martian craters, where pits are thought to form through degassing of volatile-bearing material heated by the impact. Pitted terrain on Vesta may have formed in a similar manner, which indicates that portions of the surface contain a relatively large volatile component. Exogenic materials, such as water-rich carbonaceous chondrites, may be the source of volatiles, suggesting that impactor materials are preserved locally in relatively high abundance on Vesta and that impactor composition has played an important role in shaping the asteroid's geology.

Global Fe/O and Fe/Si ratios are consistent with HED compositions. Neutron measurements confirm that a thick, diogenitic lower crust is exposed in the Rheasilvia basin, which is consistent with global magmatic differentiation. Vesta's regolith contains substantial amounts of hydrogen. The highest hydrogen concentrations coincide with older, low-albedo regions near the equator, where water ice is unstable. The young, Rheasilvia basin contains the lowest concentrations. These observations are consistent with gradual accumulation of hydrogen by infall of carbonaceous chondrites-observed as clasts in some howardites-and subsequent removal or burial of this material by large impacts.

These variations have been interpreted as evidence for multiple star formation episodes within GCs, with secondary episodes fueled, at least in part, by the ejecta of asymptotic giant branch AGB) stars from a first generation of stars. A major puzzle emerging from this otherwise plausible scenario is that the fraction of stars associated with the second episode of star formation is observed to be much larger than expected for a standard initial mass function. The present work investigates this tension by modeling the observed anti-correlation between [Na/Fe] and [O/Fe] for 20 Galactic GCs. If the abundance pattern of the retained AGB ejecta does not depend on GC mass at fixed [Fe/H], then a strong correlation is found between the fraction of current GC stellar mass composed of pure AGB ejecta, f (sub p) , and GC mass. This fraction varies from 0.20 at low masses (10 (super 4.5) M (sub Earth) ) to 0.45 at high masses (10 (super 6.5) M (sub Earth) ). The fraction of mass associated with pure AGB ejecta is directly related to the total mass of the cluster at birth; the ratio between the initial and present mass in stars can therefore be derived. Assuming a star formation efficiency of 50%, the observed Na-O anti-correlations imply that GCs were at least 10-20 times more massive at birth, a conclusion that is in qualitative agreement with previous work. These factors are lower limits because any mass-loss mechanism that removes first- and second-generation stars equally will leave f (sub p) unchanged. The mass dependence of f (sub p) probably arises because lower mass GCs are unable to retain all of the AGB ejecta from the first stellar generation. Recent observations of elemental abundances in intermediate-age Large Magellanic Cloud clusters are re-interpreted and shown to be consistent with this basic scenario. The small scatter in f (sub p) at fixed GC mass argues strongly that the process responsible for the large mass loss is internal to GCs. A satisfactory explanation of these trends is currently lacking. Copyright (Copyright) 2012. The American Astronomical Society. All rights reserved.

As in the philosophy of science in general, and in the philosophies of particular sciences, critical issues in the philosophy and sociology of astrobiology are both stimulated and illuminated by history. Among those issues are (1) epistemological issues such as the status of astrobiology as a science, the problematic nature of evidence and inference, and the limits of science; (2) metaphysical/scientific issues, including the question of defining the fundamental concepts of life, mind, intelligence, and culture in a universal context; the role of contingency and necessity in the origin of these fundamental phenomena; and whether or not the universe is in some sense fine-tuned for life and perhaps biocentric; (3) societal issues such as the theological, ethical, and worldview impacts of the discovery of microbial or intelligent life; and the question of whether the search for extraterrestrial life should be pursued at all, and with what precautions; and (4) issues related to the sociology of scientific knowledge, including the diverse attitudes and assumptions of different scientific communities and different cultures to the problem of life beyond Earth, the public "will to believe," and the formation of the discipline of astrobiology. All these overlapping issues are framed by the concept of cosmic evolution-the 13.7 billion year Master Narrative of the Universe-which may result in a physical, biological, or postbiological universe and determine the long-term destiny of humanity.

A central issue is the role that the members of the Proto-Uto-Aztecan speech community might have played in the diffusion of maize agriculture from Mesoamerica to the southwestern United States. Key to addressing this issue is determining whether an agricultural lexicon can be reconstructed for Proto-Uto-Aztecan, but despite several comparative studies of the agricultural lexica of the Uto-Aztecan languages, consensus remains elusive. A detailed reanalysis of these lexica indicates that an agriculture-related vocabulary can be reconstructed only for Proto-Southern Uto-Aztecan, supporting the conclusion that maize agriculture entered the Uto-Aztecan world after the division of the Proto-Uto-Aztecan speech community into southern and northern branches. Additional lexical and biogeographical data suggest that the Proto-Southern Uto-Aztecan speech community was located near the modern Arizona-Sonora border when its members began cultivating maize, a development that may have occurred around four thousand years ago, when the earliest evidence of maize agriculture appears in the archaeological record of the North American Southwest.

Still, its taxonomic position is not well understood, as manifested by the fact that published hypotypes have six or fewer chambered forms, and such ambiguity is due partly to a lack of updated knowledge about the primary types (a holotype and single paratype), topotypes, and hypotypes from the northwestern Pacific region. This study reexamines the species concept of Hd. yezoana through uncoated SEM observations of the primary types and newly obtained type-locality material. The holotype is synonymous with Ticinella primula Luterbacher, 1963, as judged by its uneven wall surface, pseudoplanispiral (slightly streptospiral) mode of coiling, somewhat tangentially elongate last chambers, and a possible porticus-like structure. The topotypes exhibit important characters such as supplementary apertures and well-developed portici, thus confirming the synonymy of Hd. yezoana and T. primula. This outcome, however, is troublesome because T. primula is the widely used name for this morphology, and accepting the priority of "Ticinella yezoana" affects the nomenclatural stability in Cretaceous planktonic foraminifera. Conservation of the junior name T. primula is supported not only by the insufficient preservation of the Hokkaido material but also by the concept of Article 23.9 (reversal of precedence) in the International Code of Zoological Nomenclature (4 (super th) edition, 1999), although a ruling from the Zoological Commission would be eventually necessary. The paratype, in contrast, exhibits a smooth, microperforate wall, and is identified in open nomenclature as Microhedbergella sp. A (multi-chambered form). In addition to this wall-surface feature, this potential new Microhedbergella taxon differs from the "Hd. yezoana" holotype (and hence from T. primula) by lacking a streptospiral mode of coiling, exhibiting isomorphic globular chambers between the umbilical and spiral sides, and possessing a very poorly developed or nearly absent lip. The type-locality assemblage of "Hd. yezoana" is marked by the common occurrence of several other "ticinellid" taxa (Biticinella breggiensis and at least three species of Ticinella) and Microhedbergella with very rare FAVUSELLA: The Microhedbergella specimens have a remarkably wide range of morphologies, some comparable to those recorded in a local Texas assemblage, but the rest undescribed.

It approximates an ideal chronosequence, because soils are under the same climate and vegetation, have similar topography, and are developed in the same parent material. We assessed soil development and the changes in nutrients at eleven sites along the sequence to determine rates of nutrient transformations and the potential for limitation of biological activity by nitrogen and phosphorus availability. Soils develop rapidly to podzols (Spodosols) under the super-humid climate, involving acidification and depletion of base cations in the first few hundred years, development of a bleached eluvial horizon under a thick organic horizon within 2000 years, and formation of a continuous cemented iron pan within 4000 years. Soil phosphorus concentrations decline markedly in the first few hundred years in both the organic and upper mineral soil horizons, with rapid depletion of primary mineral phosphate and the accumulation of organic phosphorus to approximately 80% of the total phosphorus in the upper mineral soil. These changes lead to an increasing degree of phosphorus limitation along the sequence, as indicated by an increase in C:P and N:P ratios and a decline in available phosphate. The rates of soil development and phosphorus depletion are more rapid than at the nearby Franz Josef post-glacial chronosequence, where glacial moraine derived from graywacke contains a relatively high phosphorus concentration and weathers into fine-textured soils. The Haast chronosequence therefore provides an important additional example of soil development linked to long-term depletion of soil phosphorus under a perudic moisture regime.

The stratigraphy of these deposits is exposed within scarps and trough walls and is thought to have formed due to climate variations in the past. Insolation has varied significantly over time and caused dramatic changes in climate, but it has remained unclear whether insolation variations could be linked to the stratigraphic record. We present a model of layer formation based on physical processes that expresses polar deposition rates of ice and dust in terms of insolation. In this model, layer formation is controlled by the insolation record, and dust-rich layers form by two mechanisms: (1) increased summer sublimation during high obliquity, and (2) variations in the polar deposition of dust modulated by obliquity variations. The model is simple, yet physically plausible, and allows for investigations of the climate control of the polar layered deposits (PLD). We compare the model to a stratigraphic column obtained from the north polar layered deposits (NPLD) (Fishbaugh, K.E., Hvidberg, C.S., Byrne, S., Russel, P.S., Herkenhoff, K.E., Winstrup, M., Kirk, R. [2010a]. Geophys. Res. Lett., 37, L07201) and show that the model can be tuned to reproduce complex layer sequences. The comparison with observations cannot uniquely constrain the PLD chronology, and it is limited by our interpretation of the observed stratigraphic column as a proxy for NPLD composition. We identified, however, a set of parameters that provides a chronology of the NPLD tied to the insolation record and consistently explains layer formation in accordance with observations of NPLD stratigraphy. This model dates the top 500 m of the NPLD back to approximately 1 million years with an average net deposition rate of ice and dust of 0.55 mm a (super -1) . The model stratigraphy contains a quasi-periodic approximately 30 m cycle, similar to a previously suggested cycle in brightness profiles from the NPLD (Laskar, J., Levrard, B., Mustard, F. [2002]. Nature, 419, 375-377; Milkovich, S., Head, J.W. [2005]. J. Geophys.

However, larval supply is difficult to monitor because long-term, high-frequency sampling is needed. The purpose of this study was to subsample an 11-year record of daily larval supply of blue crab (Callinectes sapidus) to determine the effect of sampling interval on variability in estimates of supply. The coefficient of variation in estimates of supply varied by 0.39 among years at a 2-day sampling interval and 0.84 at a 7-day sampling interval. For 8 of the 11 years, there was a significant correlation between mean daily larval supply and lagged fishery catch per trip (coefficient of correlation [r]=0.88). When these 8 years were subsampled, a 2-day sampling interval yielded a significant correlation with fishery data only 64.5% of the time and a 3-day sampling interval never yielded a significant correlation. Therefore, high-frequency sampling (daily or every other day) may be needed to characterize interannual variability in larval supply.

A major impediment to obtaining such estimates is that few statistical models are able to simultaneously account for both spatial variation in abundance and heterogeneity in detection probability, and still be amenable to large-scale applications. The hierarchical distance-sampling model of J. A. Royle, D. K. Dawson, and S. Bates provides a practical solution. Here, we extend this model to estimate habitat-specific abundance and rangewide population size of a bird species of management concern, the Island Scrub-Jay (Aphelocoma insularis), which occurs solely on Santa Cruz Island, California, USA. We surveyed 307 randomly selected, 300 m diameter, point locations throughout the 250-km super(2) island during October 2008 and April 2009. Population size was estimated to be 2267 (95% CI 1613-3007) and 1705 (1212-2369) during the fall and spring respectively, considerably lower than a previously published but statistically problematic estimate of 12 500. This large discrepancy emphasizes the importance of proper survey design and analysis for obtaining reliable information for management decisions. Jays were most abundant in low-elevation chaparral habitat; the detection function depended primarily on the percent cover of chaparral and forest within count circles. Vegetation change on the island has been dramatic in recent decades, due to release from herbivory following the eradication of feral sheep (Ovis aries) from the majority of the island in the mid-1980s. We applied best-fit fall and spring models of habitat-specific jay abundance to a vegetation map from 1985, and estimated the population size of A. insularis was 1400-1500 at that time. The 20-30% increase in the jay population suggests that the species has benefited from the recovery of native vegetation since sheep removal. Nevertheless, this jay's tiny range and small population size make it vulnerable to natural disasters and to habitat alteration related to climate change. Our results demonstrate that hierarchical distance-sampling models hold promise for estimating population size and spatial density variation at large scales. Our statistical methods have been incorporated into the R package unmarked to facilitate their use by animal ecologists, and we provide annotated code in the Supplement.

ER - TY - JOUR T1 - Dispersal of Deep-Sea Larvae from the Intra-American Seas: Simulations of Trajectories using Ocean Models AN - 1125229543; 17216205 AB - Using data on ocean circulation with a Lagrangian larval transport model, we modeled the potential dispersal distances for seven species of bathyal invertebrates whose durations of larval life have been estimated from laboratory rearing, MOCNESS plankton sampling, spawning times, and recruitment. Species associated with methane seeps in the Gulf of Mexico and/or Barbados included the bivalve "Bathymodiolus" childressi, the gastropod Bathynerita naticoidea, the siboglinid polychaete tube worm Lamellibrachia luymesi, and the asteroid Sclerasterias tanneri. Non-seep species included the echinoids Cidaris blakei and Stylocidaris lineata from sedimented slopes in the Bahamas and the wood-dwelling sipunculan Phascolosoma turnerae, found in Barbados, the Bahamas, and the Gulf of Mexico. Durations of the planktonic larval stages ranged from 3 weeks in lecithotrophic tubeworms to more than 2 years in planktotrophic starfish. Planktotrophic sipunculan larvae from the northern Gulf of Mexico were capable of reaching the mid-Atlantic off Newfoundland, a distance of more than 3000 km, during a 7- to 14-month drifting period, but the proportion retained in the Gulf of Mexico varied significantly among years. Larvae drifting in the upper water column often had longer median dispersal distances than larvae drifting for the same amount of time below the permanent thermocline, although the shapes of the distance-frequency curves varied with depth only in the species with the longest larval trajectories. Even species drifting for >2 years did not cross the ocean in the North Atlantic Drift.

We assessed variation in the species composition of trees, saplings, and seedlings, and the basal area of adult trees, in lowland temperate rain forest along the Haast chronosequence on the west coast of the South Island of New Zealand. The sequence consists of Holocene dune ridges formed following periodic earthquake disturbance and is characterized by rapid podzol development, including a marked decline in phosphorus concentrations, accumulation of a thick organic horizon, and formation of a cemented iron pan. Tree basal area increased for the first few hundred years and then declined in parallel with the decline in total soil phosphorus, consistent with the concept of forest retrogression. There were also marked changes in the composition of the tree community, from dominance by conifers on young soils to a mixed conifer-angiosperm forest on old soils. Although a variety of factors could account for these changes, partial Mantel tests revealed strong correlations between tree community composition and soil nutrients. The relationships differed among life history stages, however, because the adult tree community composition was correlated strongly with nutrients in the mineral soil, whereas the seedling community composition was correlated with nutrients in the organic horizon, presumably reflecting differences in rooting depth. The changes in the tree community at Haast are consistent with disturbance-related succession in conifer-angiosperm forests in the region, but the opposite of patterns along the nearby Franz Josef post-glacial chronosequence, where conifers are most abundant on old soils. The Haast chronosequence is therefore an important additional example of forest retrogression linked to long-term soil phosphorus depletion, and provides evidence for the role of soil nutrients in determining the distribution of tree species during long-term succession in lowland temperate rain forests in New Zealand.

Location Humid lowland forests world-wide. Methods We developed a new approach to modelling the aboveground biomass of old-growth forest (AGBmax) based on the influences of temperature on gross primary productivity (GPP) and what we call total maintenance cost (TMC), which includes autotrophic respiration as well as leaf, stem and other plant construction required to maintain biomass. We parameterized the models with measured carbon fluxes and tested them by comparing predicted AGBmax with measured AGB for another 109 old-growth sites. Results Our models explained 57% of the variation in GPP across 95 sites and 79% of the variation in TMC across 17 sites. According to the best-fit models, the ratio of GPP to maintenance cost per unit biomass (MCB) peaks at 16.5 degree C, indicating that this is the air temperature leading to the highest possible AGBmax when temperatures are constant. Seasonal temperature variation generally reduces predicted AGBmax, and thus maritime temperate climates are predicted to have the highest AGBmax. The shift in temperatures from temperate maritime to tropical climates increases MCB more than GPP, and thus decreases AGBmax. Overall, our model explains exactly 50% of the variation in AGB among humid lowland old-growth forests. Main conclusions Temperature plays an important role in explaining global variation in biomass among humid lowland old-growth forests, a role that can be understood in terms of the dual effects of temperature on GPP and TMC. Our simple model captures these influences, and could be an important tool for predicting the effects of climate change on forest carbon stores.

Relatively unappreciated, however, is that conversion of these coastal ecosystems also impacts very large pools of previously-sequestered carbon. Residing mostly in sediments, this 'blue carbon' can be released to the atmosphere when these ecosystems are converted or degraded. Here we provide the first global estimates of this impact and evaluate its economic implications. Combining the best available data on global area, land-use conversion rates, and near-surface carbon stocks in each of the three ecosystems, using an uncertainty-propagation approach, we estimate that 0.15-1.02 Pg (billion tons) of carbon dioxide are being released annually, several times higher than previous estimates that account only for lost sequestration. These emissions are equivalent to 3-19% of those from deforestation globally, and result in economic damages of $US 6-42 billion annually. The largest sources of uncertainty in these estimates stems from limited certitude in global area and rates of land-use conversion, but research is also needed on the fates of ecosystem carbon upon conversion. Currently, carbon emissions from the conversion of vegetated coastal ecosystems are not included in emissions accounting or carbon market protocols, but this analysis suggests they may be disproportionally important to both. Although the relevant science supporting these initial estimates will need to be refined in coming years, it is clear that policies encouraging the sustainable management of coastal ecosystems could significantly reduce carbon emissions from the land-use sector, in addition to sustaining the well-recognized ecosystem services of coastal habitats.

With deforestation advancing quickly, protected areas are increasingly becoming final refuges for threatened species and natural ecosystem processes. However, many protected areas in the tropics are themselves vulnerable to human encroachment and other environmental stresses. As pressures mount, it is vital to know whether existing reserves can sustain their biodiversity. A critical constraint in addressing this question has been that data describing a broad array of biodiversity groups have been unavailable for a sufficiently large and representative sample of reserves. Here we present a uniquely comprehensive data set on changes over the past 20 to 30 years in 31 functional groups of species and 21 potential drivers of environmental change, for 60 protected areas stratified across the world's major tropical regions. Our analysis reveals great variation in reserve 'health': about half of all reserves have been effective or performed passably, but the rest are experiencing an erosion of biodiversity that is often alarmingly widespread taxonomically and functionally. Habitat disruption, hunting and forest-product exploitation were the strongest predictors of declining reserve health. Crucially, environmental changes immediately outside reserves seemed nearly as important as those inside in determining their ecological fate, with changes inside reserves strongly mirroring those occurring around them. These findings suggest that tropical protected areas are often intimately linked ecologically to their surrounding habitats, and that a failure to stem broad-scale loss and degradation of such habitats could sharply increase the likelihood of serious biodiversity declines.

On California's Channel Islands, researchers have long debated the nature of late Pleistocene "fire areas," discrete red zones in sedimentary deposits, interpreted by some as prehistoric mammoth-roasting pits created by humans. Further research found no evidence that these red zones were cultural in origin, and two hypotheses were advanced to explain their origin: natural fires and groundwater processes. Radiocarbon dating, X-ray diffraction analysis, and identification of charcoal from six red zones on Santa Rosa Island suggest that the studied features date between approximately 27,500 and 11,400 cal yr BP and resulted from burning or heating, not from groundwater processes. Our results show that fire was a component of late Pleistocene Channel Island ecology prior to and after human colonization of the islands, with no clear evidence for increased fire frequency coincident with Paleoindian settlement, extinction of pygmy mammoths, or a proposed Younger Dryas impact event.

Because these causes of mortality are increasingly abundant and because some result in large bird die-offs, they have received both increased scientific attention and general media coverage. However, quantifying bird mortality remains imprecise and methods to assess whether these losses cause important biological impacts remain underdeveloped. If local mortality studies followed rigorous design and sampling schemes, allowing comparison of data and scaling up of mortality estimates to broad regions, this could lead to improved analyses. Several analytical techniques - including hierarchical and population models - show potential for improving quantification of anthropogenic mortality of birds and inference of population-level effects. Results arising from improved study designs and analytical techniques will more effectively inform decision making about policies and regulations aimed at reducing avian mortality and minimizing population impacts.

Information about the distribution, habitat associations and seasonal activity patterns of tiger beetles in the Kruger National Park is summarized from data collected in field surveys conducted between 2006 and 2011, museum specimen records and literature records. Two ecological communities in the park support large and diverse assemblages of tiger beetle species: upland 'sand veld' communities and riverine/ riparian areas. Information about adult and/or larval microhabitat associations is presented for 23 of the tiger beetle species occurring in the Kruger National Park. The park supports 25.8% of the species of Cicindelidae known to occur in South Africa. Eighteen species of tiger beetles recorded from the park (including three species of Manticora Fabricius, the species Megacephala regalis regalis Boheman, and 14 species of Dromica Dejean) are listed as 'protected species' under the South African Biodiversity Act of 2004.

The stem genus Atreta (Late Triassic to Late Cretaceous) has aragonitic denticulate hinge teeth on the right valve articulating with pitted sockets on the left valve. The same arrangement is present in Neoatreta n. gen. (Paleocene? Miocene to Recent) but with the appearance of extensive calcitic overarching of the resilifer. In Dimyella (Eocene to Recent), aragonitic teeth and sockets are still present but are modified into hook shaped denticulate teeth with corresponding sockets. All three of these genera have inner aragonitic crossed-lamellar shell layers that extend well outside the pallial line. In contrast, Dimya (Eocene to Recent) and Basiliomya (Pliocene to Recent) comprise a second clade in which aragonitic hinge teeth are absent and hinge articulation is calcitic, derived from the calcitic rim. Dimya has only weak hinge articulation and has an aragonitic inner shell layer delimited by the pallial line; in Basiliomya calcitic hinge teeth are more prominent and the entire inner shell layer inside the pallial line is foliated calcite. Diploschiza (Cretaceous, Albian to Maastrichtian), here reinstated from synonymy with Atreta, is probably a precursor of the Dimya-Basiliomya clade based on incipient calcitic hinge teeth. Predation pressures probably drove the evolution of this cemented family from its original habitat on hardgrounds in moderately deep water into much greater depths or into cryptic habitats, including submarine caves. New combinations are Dimyella malnatrensis (Corselli and Bernocchi), D. molokaia (Dall, Bartsch, and Rehder), D. similis (v. Koenen), Neoatreta dissimilis (Tate), N. filipina (Bartsch), N. kaiparaensis (Laws), N. phaidra (Woodring), and N. plana (Martin).

Quantitative bulk samples from 29 localities yielded 106,000 specimens in 145 genera. All genera were assigned to functional groups based on diet, relationship to the substrate, and mobility. Ordinations of assemblages based on quantitative data for functional groups demonstrated strong shifts in community structure, with a stark contrast between assemblages older than 5 Ma and those younger than 3.5 Ma. These changes are primarily due to an increase in the abundance of attached epifaunal bivalves (e.g., Chama, Arcopsis, and Barbatia) and a decrease in infaunal bivalves (e.g., Varicorbula and Caryocorbula). Taxa associated with seagrasses, including deposit-feeding and chemosymbiotic bivalves (e.g., Lucina), also increased in relative abundance compared to suspension feeders. The composition of bivalve assemblages is correlated with the carbonate content of sediments and the percentage of skeletal biomass that is coral. Our results strongly support the hypothesis that increases in the extent of coral reefs and Thalassia communities were important drivers of biologic turnover in Neogene Caribbean benthic communities.

Sipunculans removed from the collectors were counted, weighed, and maintained in the laboratory at 14 degree C, where they were monitored for gametogenic activity, spawning, development, and growth. In a 2-year study of seasonality, worms were most abundant in collectors retrieved in the spring and summer, and least abundant in the fall. Small animals (0.16 g) were found from May through August, but in markedly lower frequencies than small animals. Over the entire study, spawning was observed in the laboratory from April through August. We inferred from analyses of size frequencies, growth, and spawning seasonality that settlement of the larvae occurs primarily from November through April and that oceanic larval life could be as short as 7 months and as long as 12-14 months. Cleavage of fertilized eggs, as observed from laboratory spawnings, was spiral and holoblastic, resulting in a trochophore that transformed into a typical planktotrophic pelagosphera larva at 21 d. A few larvae survived as long as 2 months in the laboratory. This is the first study of biological processes in living sipunculans from the deep sea, and one of the first studies of living deep-sea wood dwellers.

Where the elevation drops below 500 m low-level wind jets pass seasonally from the Atlantic to the Pacific driving coastal upwelling in the Tropical Eastern Pacific. This paper determines if seasonal upwelling was present in five Pliocene and Pleistocene fossiliferous sites on the Pacific coast of the Burica region of the Isthmus of Panama using two independent approaches that compare bryozoan morphology and whole community composition of fossiliferous localities with material from upwelling and non-upwelling modern localities. No definitive evidence of seasonal upwelling exists in the Pliocene, implying non-analogous oceanographic conditions because of continued interoceanic connection prior to the closure of the Isthmus of Panama. Conversely, data from three mid-Pleistocene sites reveal robust evidence of strong seasonal upwelling suggesting that the elevation of the Isthmus must have been sufficiently low to permit wind-jets to form. A low-elevation Isthmus of Panama may have persisted until as recently as the mid-Pleistocene.

We evaluated natal dispersal patterns in Bicknell's thrush (Catharus bicknelli) across most of the breeding range using a 10-year data set of stable-hydrogen isotope ratios in feathers ( delta 2HF) grown on the natal area and sampled 1 year later at the first breeding site. North-eastern United States and south-eastern Canada. We used delta 2HF values of adult thrushes sampled at 25 breeding sites as prior information for assigning first-time breeders to their natal site. We calculated the minimum distance birds moved from their natal to first breeding site and fit these data to three statistical distributions for characterizing the importance of long-distance dispersal: the exponential, Weibull and half-Cauchy. Finally, we assessed differences in the probability of dispersal across the breeding range and through time to understand spatio-temporal variation in demographic connectivity. The delta 2HF values of first-time breeders were lower compared with those of adults, a difference that was greater at the southern compared with northern breeding range extreme. Assignment tests accounting for age differences in delta 2HF suggested that most birds dispersed < 200 km from their natal area and within the centre of the breeding range, whereas comparatively few individuals dispersed up to 700 km. A Weibull distribution provided the best fit to these data. Two of three corrections for age differences in delta 2HF indicated that natal dispersal probability declined by 30-38% from 1996 to 2005. Our findings suggest that estimating natal dispersal with delta 2HF measurements may contribute to understanding the resilience of geographically isolated Bicknell's thrush populations. Declining natal dispersal may be symptomatic of observed population declines and could compound this trend by limiting demographic exchange between habitat patches predicted to be increasingly isolated by natural and anthropogenic habitat changes.

AN - 1034795755; 22763283 AB - Boring isopods damage expanded polystyrene floats under docks and, in the process, expel copious numbers of microplastic particles. This paper describes the impacts of boring isopods in aquaculture facilities and docks, quantifies and discusses the implications of these microplastics, and tests if an alternate foam type prevents boring. Floats from aquaculture facilities and docks were heavily damaged by thousands of isopods and their burrows. Multiple sites in Asia, Australia, Panama, and the USA exhibited evidence of isopod damage. One isopod creates thousands of microplastic particles when excavating a burrow; colonies can expel millions of particles. Microplastics similar in size to these particles may facilitate the spread of non-native species or be ingested by organisms causing physical or toxicological harm. Extruded polystyrene inhibited boring, suggesting this foam may prevent damage in the field. These results reveal boring isopods cause widespread damage to docks and are a novel source of microplastic pollution. Copyright © 2012 Elsevier Ltd. All rights reserved.

We expect that, in areas with large-scale land use changes, legacies from previous land uses persist and affect current ecosystem responses to climate-associated disturbances like fire. This study analyses whether post-fire vegetation dynamics may differ according to specific historical land use histories in a Mediterranean forest landscape of about 60,000ha that was burnt by extensive fires. For that, we assessed land use history of the whole area through the second half of the XXth century, and evaluated the post-fire regeneration success in terms of: (i) forest cover and (ii) tree species composition (biotic-dispersed, resprouter species, Quercus spp. vs. wind-dispersed species with or without fire-resistant seed bank, Pinus spp.). Results showed that stable forest areas exhibited a higher post-fire recovery than younger forests. Furthermore, the longer since crop abandonment translates into a faster post-fire recovery. Results highlight that to anticipate the impacts of disturbances on ecosystems, historical land trajectories should be taken into account.

This differed from its probable North American ancestor, A. acadicus, in its more robust hindlimb elements, smaller head, and a possible tendency for smaller wing elements. Its colonization was probably made possible by the unique conditions of suitable habitat for hunting, roosting, and nesting afforded by Bermuda, including the presence of woodpeckers (Picidae) that would have excavated nest sites suitable for the owls in the endemic palm trees (Sabal bermudana). From accounts dating to the early 1600s, the species appears likely to have persisted into the historic period.

In this paper, we study the orbital stability of P4, the most recently discovered moon in the Pluto system. This newfound companion orbits near the plane of the Pluto-Charon (PC) binary, roughly halfway between the two minor moons Nix and Hydra. We use a suite of few body integrations to constrain the masses of Nix and Hydra, and the orbital parameters of P4. For the system to remain stable over the age of the solar system, the masses of Nix and Hydra likely do not exceed 5 X 10 (super 16) kg and 9 X 10 (super 16) kg, respectively. These upper limits assume a fixed mass ratio between Nix and Hydra at the value implied by their median optical brightness. Our study finds that stability is more sensitive to their total mass and that a downward revision of Charon's eccentricity (from our adopted value of 0.0035) is unlikely to significantly affect our conclusions. Our upper limits are an order of magnitude below existing astrometric limits on the masses of Nix and Hydra. For a density at least that of ice, the albedos of Nix and Hydra would exceed 0.3. This constraint implies they are icy, as predicted by giant impact models. Even with these low masses, P4 only remains stable if its eccentricity e < or = 0.02. The 5:1 commensurability with Charon is particularly unstable, combining stability constraints with the observed mean motion places the preferred orbit for P4 just exterior to the 5:1 resonance. These predictions will be tested when the New Horizons satellite visits Pluto. Based on the results for the PC system, we expect that circumbinary, multi-planet systems will be more widely spaced than their singleton counterparts. Further, circumbinary exoplanets close to the three-body stability boundary, such as those found by Kepler, are less likely to have other companions nearby. Copyright (Copyright) 2012.

We accurately measure the silicate absorption features at lambda approximately 9.7 mu m in archival low-resolution (R approximately 57-127) Spitzer Infrared Spectrograph spectroscopy, and show that only a minority ( nearly equal 45%) of nearby Compton-thick AGNs have strong Si-absorption features (S (sub 9.7) = ln (f (sub int) /f (sub obs) )> or = 0.5) which would indicate significant dust attenuation. The majority ( nearly equal 60%) are star formation dominated (AGN:SB < 0.5) at mid-IR wavelengths and lack the spectral signatures of AGN activity at optical wavelengths, most likely because the AGN emission lines are optically extinguished. Those Compton-thick AGNs hosted in low-inclination-angle galaxies exhibit a narrow range in Si-absorption (S (sub 9.7) approximately 0-0.3), which is consistent with that predicted by clumpy-torus models. However, on the basis of the IR spectra and additional lines of evidence, we conclude that the dominant contribution to the observed mid-IR dust extinction is dust located in the host galaxy (i.e., due to disturbed morphologies, dust lanes, galaxy inclination angles) and not necessarily a compact obscuring torus surrounding the central engine.

a pair of planets with neighboring orbits and dissimilar densities AN - 1080608137; 2012-084262 AB - In the solar system, the planets' compositions vary with orbital distance, with rocky planets in close orbits and lower-density gas giants in wider orbits. The detection of close-in giant planets around other stars was the first clue that this pattern is not universal and that planets' orbits can change substantially after their formation. Here, we report another violation of the orbit-composition pattern: two planets orbiting the same star with orbital distances differing by only 10% and densities differing by a factor of 8. One planet is likely a rocky "super-Earth," whereas the other is more akin to Neptune. These planets are 20 times more closely spaced and have a larger density contrast than any adjacent pair of planets in the solar system.

Blends dilute the transit signal, causing the planet to appear smaller than it really is, or produce a false-positive detection when the target star is blended with eclipsing binary stars. This paper reports on high spatial-resolution adaptive optics images of 90 Kepler planetary candidates. Companion stars are detected as close as 0''.1 from the target star. Images were taken in the near-infrared (J and K s bands) with ARIES on the MMT and PHARO on the Palomar Hale 200 inch telescope. Most objects (60%) have at least one star within 6" separation and a magnitude difference of 9. Eighteen objects (20%) have at least one companion within 2" of the target star; six companions (7%) are closer than 075. Most of these companions were previously unknown, and the associated planetary candidates should receive additional scrutiny. Limits are placed on the presence of additional companions for every system observed, which can be used to validate planets statistically using the BLENDER method. Validation is particularly critical for low-mass, potentially Earth-like worlds, which are not detectable with current-generation radial velocity techniques. High-resolution images are thus a crucial component of any transit follow-up program.

The authors ignored peaks that were "far outside" of these size ranges, thus precluding recognition of additional alleles, including those that have been reported in other populations of this species. We are also concerned about the lack of reproducibility in the scoring methods utilized because the authors did not define a threshold for deciding when peaks should be ignored.

A densely pitted crater-related unit has been identified in images of 204 craters from the Mars Reconnaissance Orbiter. This sample of craters are nearly equally distributed between the two hemispheres, spanning from 53 degrees S to 62 degrees N latitude. They range in diameter from approximately 1 to 150 km, and are found at elevations between -5.5 to +5.2 km relative to the martian datum. The pits are polygonal to quasi-circular depressions that often occur in dense clusters and range in size from ?10 m to as large as 3 km. Pit sizes scale with both the host crater's diameter and the host deposit size. These pits have subtle raised rims, and unlike primary and secondary impact craters, they lack well-defined ejecta deposits and overlapping stratigraphic relationships. They also lack any sign of any preferential alignment expected of volcanic or tectonic collapse features. Morphologic and stratigraphic evidence in support of an impact origin includes the observation that pitted materials primarily occur as ponded and flow-like deposits on crater floors, behind terraces, and infilling the lowest local topographic depressions atop the ejecta blanket-similar to the distribution of impact melt-bearing bodies on the Moon. Based on the observations and comparisons to terrestrial and lunar analogs, we conclude that the pit-bearing materials are impactite deposits. The presence of these deposits in older craters, where preserved, suggests that they have formed on Mars throughout most of its geologic history; thus, understanding their origin may help to constrain the hydrological and climate history of Mars.

Increasingly more information has been published about primates in agroecosystems but a general synthesis of the diversity of agroecosystems that primates use or which primate taxa are able to persist in these anthropogenic components of the landscapes is still lacking. Because of the continued extensive transformation of primate habitat into human-modified landscapes, it is important to explore the extent to which agroecosystems are used by primates. In this article, we reviewed published information on the use of agroecosystems by primates in habitat countries and also discuss the potential costs and benefits to human and nonhuman primates of primate use of agroecosystems. The review showed that 57 primate taxa from four regions: Mesoamerica, South America, Sub-Saharan Africa (including Madagascar), and South East Asia, used 38 types of agroecosystems as temporary or permanent habitats. Fifty-one percent of the taxa recorded in agroecosystems were classified as least concern in the IUCN Red List, but the rest were classified as endangered (20%), vulnerable (18%), near threatened (9%), or critically endangered (2%). The large proportion of threatened primates in agroecosystems suggests that agroecosystems may play an important role in landscape approaches to primate conservation. We conclude by discussing the value of agroecosystems for primate conservation at a broad scale and highlight priorities for future research. Am. J.

Feature width, defined as the basal break in slope along the profile to either side of the crest, represents a good standard for comparison of profile attributes across more than three orders of magnitude. Aspect ratio (height/width) as a function of log width separates measurements into clusters representing differing mechanisms of formation. Scaling both height and distance for individual profiles by feature width facilitates comparison of profile shapes across three orders of magnitude in width. The data presented here should prove useful for evaluating possible mechanisms of origin for aeolian features observed remotely, including on planetary bodies.

Despite the widespread use of seismic reflection technology for oil and gas exploration, no studies have investigated the response of primate populations to this disturbance in the Amazon. We conducted distance sampling along transects in pristine, unhunted lowland rain forest inside a large oil concession (Block 39) in the northern Peruvian Amazon with ongoing 2D seismic exploration. We aimed to investigate seismic exploration effects on local primate abundance, with a particular focus on the region's most endangered primates, lowland woolly monkeys ( Lagothrix poeppigii ) and white-bellied spider monkeys ( Ateles belzebuth ). We sampled transects before the arrival of exploration crews (control) and during the seismic operation (disturbance) and compared primate counts using mixed-effect models. We confirmed the presence of nine species of primates along sampled transects. Abundance of primate groups (species pooled) was not different between the control and disturbance period, yet abundance of primate individuals was significantly lower in the disturbance period. Although we encountered groups of Ateles belzebuth equally often during the control and disturbance periods, overall counts of individuals of this species were lower during the disturbance period owing to lower subgroup sizes. This suggests this species may have responded, at least temporarily, with localized spatial avoidance, and that it may be particularly sensitive to human disturbance regardless of hunting pressure. Our overall density estimate for Lagothrix poeppigii (30.6/km 2 ) approaches the highest reported for the species. Although the relatively temporary nature of 2D seismic exploration may limit its effect on primate species, our data indicate some species may respond more negatively than others.

However, from the Middle-Upper Triassic Madygen Formation of southwestern Kyrgyzstan, we describe the first association between an isoetalean host, Isoetites (a quillwort), and a pattern of elliptical egg insertion scars that altered the host's live plant tissues. This ovipositional damage, in some cases deployed in a stereotypical zigzag pattern, was most likely caused by small damselfly-like insects from the extinct suborder Archizygoptera of the order Odonatoptera (dragonflies). If this identification is correct, it indicates considerable behavioral stasis of dragonflies extending deep into the Mesozoic. Our detection of lycopsid ovipositional damage adds to the list of major plant hosts from the preangiospermous Mesozoic that were resources for host use by egg-laying dragonflies, particularly horsetails, ferns, and seed plants that included conifers, peltasperms, corystosperms, ginkgophytes, bennettitaleans and probably cycads.

The occurrence of birnessite phases as fine-grained materials with corresponding high-surface areas makes them effective in controlling soil sediment and groundwater compositions, but difficult to structurally characterize using conventional analytical methods. Molecular simulations provide an alternative approach in which many details of bulk and interlayer structure can be ascertained to supplement and interpret the experimental findings. Classical and electronic structure methods are used to evaluate Na-, K-, and Ba-birnessite phases. Computational results compare favorably with structures obtained by synchrotron X-ray diffraction and difference electron Fourier mapping of the interlayer region. Based on the analysis of the 1 ns atomic trajectories, dynamics of water molecules is enhanced in the interlayer of K-birnessite relative to the limited motion of water molecules and cations in the other birnessite phases. Molecular dynamics simulations of rancieite, a complex layered manganese oxide having octahedral vacancies, indicate multiple sites for Ca (super 2+) in the interlayer. In addition to manganese layer charge and layer structure, the hydration enthalpy for the interlayer cation affects the structure and dynamics of the interlayer in birnessite minerals.

However, many hosts support mutualist guilds, and interactions among mutualists make the prediction of aggregate effects difficult. Here, we apply a factorial experiment to interactions of 'guard' crustaceans that defend their coral host from seastar predators. Predation was reduced by the presence of mutualists (15% reduction in predation frequency and 45% in volume of coral consumed). The frequency of attacks with both mutualists was lower than with a single species, but it did not differ significantly from the expected frequency of independent effects. In contrast, the combined defensive efficacy of both mutualist species reduced the volume of coral tissue lost by 73%, significantly more than the 38% reduction expected from independent defensive efforts, suggesting the existence of a cooperative synergy in defensive behaviors of 'guard' crustaceans. These emergent 'multiple defender effects' are statistically and ecologically analogous to the emergent concept of 'multiple predator effects' known from the predation literature.

Aqueous Mn(II) is removed via oxidative precipitation of Mn(III/IV) oxides catalyzed by Mn(II)-oxidizing microbes and Mn oxide (MnO (sub x) ) surfaces. The relative importance of these two processes for Mn removal was examined in laboratory experiments conducted with sediments and CMD collected from eight Mn(II)-removal beds in Pennsylvania and Tennessee, USA. Sterile and non-sterile sediments were incubated in the presence/absence of air and presence/absence of fungicides to operationally define the relative contributions of Mn removal processes. Relatively fast rates of Mn removal were measured in four of the eight sediments where 63-99% of Mn removal was due to biological oxidation. In contrast, in the four sediments with slow rates of Mn(II) removal, 25-63% was due to biological oxidation. Laboratory rates of Mn(II) removal were correlated (R (super 2) =0.62) to bacterial biomass concentration (measured by phospholipid fatty acids (PLFA)). Furthermore, laboratory rates of Mn(II) removal were correlated (R (super 2) =0.87) to field-scale performance of the Mn(II)-removal beds. A practical recommendation from this study is to include MnO (sub x) -coated limestone (and associated biomass) from an operating bed as "seed" material when constructing new Mn(II)-removal beds.

We used microsatellite and mitochondrial data to infer genetic structure, gene flow, and fluctuations in population demography through evolutionary time. Patterns in the genetic signatures were used to assess predictions associated with the three population models: panmixia, metapopulation, and isolated populations. Population genetic structure was observed along with asymmetry in gene flow estimates that changed directionality at different temporal scales, consistent with metapopulation model predictions. Therefore, Northern Goshawk assemblages located in the Alexander Archipelago and coastal British Columbia interact through a metapopulation framework, though they may not fit the classic model of a metapopulation. Long-term population sources (coastal mainland British Columbia) and sinks (Revillagigedo and Vancouver islands) were identified. However, there was no trend through evolutionary time in the directionality of dispersal among the remaining assemblages, suggestive of a rescue-effect dynamic. Admiralty, Douglas, and Chichagof island complex appears to be an evolutionarily recent source population in the Alexander Archipelago. In addition, Kupreanof island complex and Kispiox Forest District populations have high dispersal rates to populations in close geographic proximity and potentially serve as local source populations. Metapopulation dynamics occurring in the Alexander Archipelago and coastal British Columbia by Northern Goshawks highlight the importance of both occupied and unoccupied habitats to long-term population persistence of goshawks in this region.

Spatial and temporal availability of pollen helps shape bee foraging behaviour and productivity, which has been studied in great detail at the landscape level, but never in a diverse tropical forest. 2. To study the effect of spatio-temporal variation in resource distribution on pollen use and productivity, we identified pollen from spatially explicit nest collections of two generalist sweat bees, Megalopta genalis Meade-Waldo and M. centralis Friese, from Barro Colorado Island, Panama, a 50-ha forest dynamics plot during the 2007 dry and early wet seasons. Pollen from nests collected in 1998-1999 without spatial information was also identified. 3. Bees used pollen of at least 64 species; many of these occurred in only one collection. The 2007 collections contained pollen of 35 different species, but were dominated by five species, especially Hura crepitans L. and Pseudobombax septenatum (Jacq.) Dugand. 4. Temporal availability, but not distance from nest, influenced flower use at a 50-ha scale. 5. Body size was not associated with minimum flight distance as inferred from pollen collections. 6. Nest productivity and pollen diversity decreased from the dry to wet seasons, mirroring community-level availability of floral resources. 7. Results suggest that on a scale of 50 ha, bees are choosing certain host plant species regardless of distance from the nest, but adjusting foraging behaviour opportunistically based on the temporal availability of host flowers.

The present study examined both univariate and multivariate temperature-mediated plasticity of life-history traits, as well as temperature-mediated trade-offs in egg size and clutch size, in two planktotrophic species of marine slipper limpets, Crepidula. Previous work with two species of Crepidula with large eggs and lecithotrophic development has shown a significant effect of temperature on egg size and hatching size. To further examine the effect of temperature on egg size in Crepidula, the effects of temperature on egg size and hatching size, as well as the possible trade-offs with other the life-history features, were examined for two planktotrophic species: Crepidula incurva and Crepidula cf. marginalis. Field-collected juveniles were raised at 23 or 28 degree C and egg size, hatching size, capsules/brood, eggs/capsule, time to hatch, interbrood interval, and final body weight were recorded. Consistent with results for the lecithotrophic Crepidula, egg size and hatching size decreased with temperature in the planktotrophic species. The affects of maternal identity and individual brood account for more than half of the intraspecific variation in egg size and hatching size. Temperature also showed a significant effect on reproductive rate, with time to hatch and interbrood interval both decreasing with increasing temperature. However, temperature had contrasting effects on the number of offspring. Crepidula cf. marginalis has significantly more eggs/capsule and therefore more eggs per brood at 28 degree C compared to 23 degree C, although capsules/brood did not vary with temperature. Crepidula incurva, on the other hand, produced significantly more capsules/brood and more eggs per brood at the lower temperature, whereas the number of eggs/capsule did not vary with temperature. The phenotypic variance-covariance matrix of life-history variables showed a greater response to temperature in C.incurva than in C. cf. marginalis, and temperature induced trade-offs between offspring size and number differ between the species. These differences suggest that temperature changes as a result of seasonal upwelling along the coast of Panama will effect the reproduction and evolution of life histories of these two co-occurring species differently.[copy 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, times times , times times - times times .

AN - 1028029005; 16917070 AB - 1.Ancient, deep lakes have traditionally been considered as stable, ecological islands, well buffered from environmental change because of their great depth. However, they are not immune to anthropogenic and climatic stress. Ecosystems of the permanently stratified warm Lakes Malawi and Tanganyika in the Great East African Rift are particularly delicate. Their stratification regime has historically limited the distribution of benthic biota to a 'bathtub ring of biodiversity', namely substrata in the upper, oxygenated water layer. 2.We use historical data on the endemic deep-water molluscs of these lakes to assess present-day stress on their benthic ecosystems. During the 20th century, these molluscs have probably decreased in abundance and migrated to shallower water. 3.These apparent trends have a significance beyond species-based conservation, foremost because deep-water organisms heavily rely on the position and temporal stability of the oxycline and therefore provide an early warning of large-scale changes in the distribution of dissolved oxygen. Oxygen demands have increased in the East African Great Lakes over the last century whereas ventilation of deep water has remained the same or declined. 4.The combination of these factors is resulting in a narrowing of the ring of biodiversity and a changed nutrient flux through this ring. Reduction in the habitat available inevitably puts biota at risk, whereas changes in nutrient flux may cause shifts in the entire ecosystem or the collapse of parts of it. 5.Considering the socioeconomic value of these lakes and the potentially grave implications for their faunal biodiversity and entire ecosystems, existing evidence of faunal decline, especially in taxa that depend strongly on the stratification regime, is of great concern. Moreover, because the factors responsible are widespread and include surface-water warming, increased run-off and eutrophication, respiration stress may also develop in other tropical and subtropical lakes.

New cores confirm the existence of a more expanded and continuous Upper Cretaceous sequence than had previously been documented in the Lindi and Kilwa regions of southeastern coastal Tanzania. This TDP expedition cored 684.02m at eight Upper Cretaceous sites (TDP Sites 28-35) and a thin Paleocene section (TDP Site 27). TDP Sites 29, 30, 31 and 34 together span the lowermost Turonian to Coniacian (PF Whiteinella archaeocretacea to Dicarinella concavata Zones and CN Zones UC6a-9b), with TDP Site 31 being the most biostratigraphically complete Turonian section found during TDP drilling. A discontinuous section from the Santonian-upper Campanian (PF D. asymetrica to Radotruncana calcarata Zones and CN Zones UC12-16) was collectively recovered at TDP Sites 28, 32 and 35, while thin sequences of the lower Cenomanian (PF Thalmanninella globotruncanoides Zone and CN subzones UC3a-b) and middle Paleocene (Selandian; PF Zone P3a and CN Zone NP5) were cored in TDP Sites 33 and 27, respectively. Records of delta (super 13) C (sub org) and delta (super 13) C (sub carb) from bulk sediments generated for all the Cretaceous sites show largely stable values through the sections. Only a few parallel delta (super 13) C (sub org) and delta (super 13) C (sub carb) shifts have been found and they are interpreted to reflect local processes. The delta (super 18) O (sub carb) record, however, is consistent with Late Cretaceous cooling trends from the Turonian into the Campanian. Lithologies of these sites include thick intervals of claystones and siltstones with locally abundant, finely-laminated fabrics, irregular occurrences of thin sandstone layers, and sporadic bioclastic debris (e.g., inoceramids, ammonites). Minor lithologies represent much thinner units of up to medium-grained, massive sandstones. The %CaCO (sub 3) ( approximately 5-40%) and %C (sub org) ( approximately 0.1-2%) are variable, with the highest %CaCO (sub 3) in the lower Campanian and the highest %C (sub org) in the Turonian. Lithofacies analysis suggests that deposition of these sediments occurred in outer shelf-upper slope, a setting that agrees well with inferences from benthic foraminifera and calcareous dinoflagellates.

The Messel (47.8 Ma) and Eckfeld (44.3 Ma) deposits offer a rare opportunity to take a census of two, deep-time ecosystems occurring during a greenhouse system. An understanding of the long-term consequences of extreme warming and cooling events during this interval, particularly on angiosperms and insects that dominate terrestrial biodiversity, can provide insights into the biotic consequences of current global climatic warming. We compare insect-feeding damage within two middle Eocene fossil floras, Messel and Eckfeld, in Germany. From these small lake deposits, we studied 16,082 angiosperm leaves and scored each specimen for the presence or absence of 89 distinctive and diagnosable insect damage types (DTs), each of which was allocated to a major functional feeding group, including four varieties of external foliage feeding, piercing- and-sucking, leaf mining, galling, seed predation, and oviposition. Methods used for treatment of presence-absence data included general linear models and standard univariate, bivariate and multivariate statistical techniques. Our results show an unexpectedly high diversity and level of insect feeding than comparable, penecontemporaneous floras from North and South America. In addition, we found a higher level of herbivory on evergreen, rather than deciduous taxa at Messel. This pattern is explained by a ca. 2.5-fold increase in atmospheric CO (sub 2) that overwhelmed evergreen antiherbivore defenses, subsequently lessened during the more ameliorated levels of Eckfeld times. These patterns reveal important, previously undocumented features of plant-host and insect-herbivore diversification during the European mid Eocene.

While open ocean samples are the standard source for these measures, shelf settings can also provide detailed records. However, the implementation of shelf data for these purposes has been hindered by the perception that local environmental conditions (such as freshwater influx) confound regional and global signals. Here, we directly evaluate this concern by assessing the spatial variability in the isotopic composition of biogenic carbonate precipitated along the depositional strike of an inner shelf environment. Data are derived from mollusc shells collected from a stratigraphically restricted, transgressive unit in the early Eocene (55Ma) of the US Gulf Coastal Plain (GCP). Lithofacies and fossil assemblages suggest that an estuary was present in the westernmost study region, whereas more typically marine facies predominated elsewhere. Isotopic composition varies predictably with paleoenvironmental setting; shells from the estuary have delta 18O values and 87Sr/86Sr ratios that reflect high freshwater input. Specimens in the eastern GCP, however, from within and between outcrops separated by up to 400km, all yield similar results. Serial microsampling reveals congruence not only in mean delta 18O values, but also in winter and summer extremes. Estimated paleotemperatures (mean annual temperature of 26 degree C) agree well with proxy and model evidence for the early Eocene and the GCP, and 87Sr/86Sr ratios are consistent with the established early Eocene seawater ratio. The fidelity of isotopic values relative to environment indicates that shallow shelf records have much to contribute to studies of ancient climate and ocean chemistry.

We report the results of confocal Raman imaging spectroscopy on 11 martian meteorites, spanning about 4.2 billion years of martian history. Ten of the meteorites contain abiotic macromolecular carbon (MMC) phases detected in association with small oxide grains included within high-temperature minerals. Polycyclic aromatic hydrocarbons were detected along with MMC phases in Dar al Gani 476. The association of organic carbon within magmatic minerals indicates that martian magmas favored precipitation of reduced carbon species during crystallization. The ubiquitous distribution of abiotic organic carbon in martian igneous rocks is important for understanding the martian carbon cycle and has implications for future missions to detect possible past martian life.

To provide a simple baseflow separation method for small watersheds, we describe a new precipitation-based technique known as the Sliding Average with Rain Record (SARR). The SARR uses rainfall data to justify each separation of the hydrograph. SARR has several advantages such as: it shows better consistency with the precipitation and discharge records, it is easier and more practical to implement, and it includes a method of event identification based on precipitation and quickflow response. SARR was derived from the United Kingdom Institute of Hydrology (UKIH) method with several key modifications to adapt it for small watersheds (<50 km (super 2) ). We tested SARR on watersheds in the Choptank Basin on the Delmarva Peninsula (US Mid-Atlantic region) and compared the results with the UKIH method at the annual scale and the hydrochemical method at the individual event scale. Annually, SARR calculated a baseflow index that was approximately 10% higher than the UKIH method due to the finer time step of SARR (1 d) compared to UKIH (5 d). At the watershed scale, hydric soils were an important driver of the annual baseflow index likely due to increased groundwater retention in hydric areas. At the event scale, SARR calculated less baseflow than the hydrochemical method, again because of the differences in time step (hourly for hydrochemical) and different definitions of baseflow. Both SARR and hydrochemical baseflow increased with event size, suggesting that baseflow contributions are more important during larger storms. To make SARR easy to implement, we have written a MatLab program to automate the calculations which requires only daily rainfall and daily flow data as inputs.

The principal cause of this millennial-scale hiatus in reef growth was increased variability of the El Nino-Southern Oscillation (ENSO) and its coupling with the Intertropical Convergence Zone. The hiatus was a Pacific-wide phenomenon with an underlying climatology similar to probable scenarios for the next century. Global climate change is probably driving eastern Pacific reefs toward another regional collapse.

Domestic animals belong to all Linnaean animal classes -- mammals, birds, reptiles, amphibians, fish, insects, and even, arguably, bacteria. Raised for food, secondary products, labor, and companionship, domestic animals have become intricately woven into human economy, society, and religion. Animal domestication is an on-going process, as humans, with increasingly sophisticated technology for breeding and rearing animals in captivity, continue to bring more and more species under their control. Understanding the process of animal domestication and its reciprocal impacts on humans and animal domesticates requires a multidisciplinary approach. This paper brings together recent research in archaeology, genetics, and animal sciences in a discussion of the process of domestication, its impact on animal domesticates, and the various pathways humans and their animal partners have followed into domestication.

AN - 1093446829; 16882183 AB - Mode of development in marine invertebrates has been largely viewed as a dichotomy between small eggs that develop into free-living planktotrophic larvae and large eggs that bypass the larval stage and develop directly into juveniles. Modes of development that could be categorized as "intermediate" between these two extremes include facultative feeding larvae, short-lived planktotrophic larvae, dispersal dimorphisms, and poecilogony (in which nutritional mode varies within a species). These intermediates are rare. The few species-level phylogenies available that include them do not generally support the interpretation of intermediates as necessary, ephemeral transitional forms. Instead, they support the idea that intermediates are well adapted to their environments but that either these environments are short-lived relative to the frequency of speciation, or speciation events are associated with shifts in the mode of development. Each of the different intermediate forms could have evolved in response to variable environments. The phenotypically plastic intermediates could be a response to predictable environmental variation. Facultative feeding larvae and short-lived planktotrophic larvae could reflect conservative bet-hedging in response to unpredictable environmental variation, whereas poecilogony with mixed clutches could represent the alternative: diversifying bet-hedging. Since environmental variability is common, it remains an enigma why these intermediates are so rare. Discovery of more intermediates, and their careful description in terms of the level of variation expressed within, and among, clutches, and among females and populations, as well as determination of the genetic and environmental influences on this variation, will provide valuable test-cases for theories of the evolution of alternative phenotypes.

Even less is known about the potential interaction of plants and vertebrates. Here we report the discovery of a small stand of 34 probable Supaia White plants from the Abo Formation of New Mexico. The plants were growing on a mudflat, subject to periodic flooding and exposure. The same mudflat hosts trackways of vertebrates that appear to have walked around or between the Supaia plants. The stems are preserved as molds, and vary from 20 mm to 70 mm in diameter, averaging 42.4 mm, indicating heights of approximately 2.5-4 m. The plants, which may be described as small trees given their estimated height, are as close as 110 mm to their nearest neighbor and average nearly 300 mm apart. A series of lines or filled fissures, which we interpret as roots, radiates from the base of each stem. Leaves of Supaia thinfeldioides White are the only foliage found in association with these stems, on bedding planes above and at the base of the lowest expression of the stem molds. Associated vertebrate trackways either congregate around some of the stems or wend their way between the stems and include those of a single large temnospondyl amphibian (Limnopus Marsh) and many of small predatory parareptiles (Dromopus Marsh). This study demonstrates that S. thinfeldiodes were small-statured, weedy, opportunistic plants. It also shows that contemporaneous vertebrates prowled such environments, presumably either for food, shelter, or both given detectable pace and path.

Whereas P. mushaisaensis is unique in aspects of its shell morphology, it shares many diagnostic characteristics of bothremydid pleurodirans, including a long exoccipital-quadrate contact, a very low and rounded almost circular carapace, and a thinner internal bone cortex than that of the external cortex in both the carapace and plastron. With a maximum carapacial length of 151 cm, P. mushaisaensis is the largest known bothremydid turtle and represents the first occurrence of bothremydids in the Paleogene of South American tropics. Results from a cladistic analysis of bothremydids indicate that P. mushaisaensis shares a close relationship with Foxemys mechinorum from the Late Cretaceous of Europe, indicating a wide-spread geographical distribution for bothremydines during the Late Cretaceous-Paleocene.

The endemic Hawaiian petrel (Pterodroma sandwichensis) is one such species. Today it is endangered, and known to breed only on the islands of Hawaii, Maui, Lanai and Kauai. Historical records indicate that a large population formerly bred on Molokai as well, but this population has recently been extirpated. Given the great dispersal potential of these petrels, it remains unclear if populations are genetically distinct and which factors may contribute to isolation between them. We sampled petrels from across their range, including individuals from the presumably extirpated Molokai population. We sequenced 524 bp of mitochondrial DNA, 741 bp from three nuclear introns, and genotyped 18 microsatellite loci in order to examine the patterns of divergence in this species and to investigate the potential underlying mechanisms. Both mitochondrial and nuclear data sets indicated significant genetic differentiation among all modern populations, but no differentiation was found between historic samples from Molokai and modern birds from Lanai. Population-specific nonbreeding distribution and strong natal philopatry may reduce gene flow between populations. However, the lack of population structure between extirpated Molokai birds and modern birds on Lanai indicates that there was substantial gene flow between these populations and that petrels may be able to overcome barriers to dispersal prior to complete extirpation. Hawaiian petrel populations could be considered distinct management units, however, the dwindling population on Hawaii may require translocation to prevent extirpation in the near future.

A clear understanding of the limitations of such datasets, including the potential for biases in the statistical methods used to analyze them, is therefore crucial. The classical Zonneveld model (CZ) can extract estimates of a suite of demographic parameters from transect count datasets, and has also been used in theoretical analyses of protandry and reproductive asynchrony. The CZ relies on strong assumptions about the emergence and death processes underlying observed transect count datasets. Though reasonable as a starting place, a growing body of empirical evidence suggests these assumptions will, in many cases, not hold. Here, I explore how violations of these assumptions bias CZ-based estimates of two key population parameters: total population size and mean individual lifespan. To do this, I generalize the Zonneveld model by relaxing the symmetrical emergence distribution and constant death rate assumptions such that the generalized models contain the CZ as a special case. Using the generalized models as data generating processes, I then show that the CZ is able to closely mimic the shape of the abundance time course produced by either variant of the generalized model under a wide range of conditions, but produces highly biased estimates of population size and mean lifespan in doing so. My analysis therefore demonstrates both that the CZ is not robust to violations of its emergence and death assumptions, and that a good observed fit to transect count data does not mean these assumptions are satisfied.

Its fertile delta lay at the heart of ancient Egyptian civilization, however little is known of its morpho-sedimentary response to basin-wide changes in Holocene hydrology. Here, we present two well-resolved records from the Nile delta (based on approximately 320 radiocarbon dates) to reconstruct the timing and rhythm of catchment-scale modifications during the past 8000 years. On the orbital timescale, we demonstrate that Nilotic hydrology and sedimentation have responded to low-latitude insolation forcing while, on sub-millennial timescales, many of the major phases of deltaic modification were mediated by climate events linked to El Nino Southern Oscillation-type (ENSO) variability.

However, reproductive success in captivity to date has not been sufficient to sustain reintroduction efforts. The goal of this study was to investigate patterns of fecal progestagen and glucocorticoid excretion in females during mating, gestation, and lactation and identify hormonal relationships to reproductive success. Fresh fecal samples were collected from 48 adult, female rabbits over 3 breeding seasons at a frequency of 4-7 samples per week. Results showed that a large (17-fold) increase in progestagen concentrations 1 day after mating provides a reliable means of determining if a successful mating occurred. In general, higher glucocorticoid concentrations during the breeding season, specifically during mating and gestation, were associated with lower reproductive success. Females that failed to conceive during the breeding season had higher glucocorticoid and lower progestagen baseline concentrations than females that did conceive. Glucocorticoid excretion during late gestation, but not lactation, was negatively associated with litter success, suggesting it affects offspring survival more during the prenatal than the postnatal period. Progestagen and glucocorticoid concentrations at the end of gestation were positively related to litter size, which may be an important factor in juvenile survival. In summary, higher concentrations of fecal glucocorticoids during the breeding season were associated with reduced conception rates and survival of subsequent litters. Ultimately, identifying what factors cause elevated glucocorticoids in pygmy rabbits could provide opportunities to alleviate negative stressors and increase the reproductive output of the captive population.

For the past 9 decades, this population has been considered either a subspecies of S. obscurusMerriam, 1895, S. vagransBaird, 1857, or S. monticolaMerriam, 1890; or an undifferentiated population of S. ornatusMerriam, 1895. Aside from the changing taxonomic landscape that contextualizes the genus Sorex, previous study of S. obscurus parvidens has been retarded by the perception of limited available samples (typically, fewer than 8 specimens); misinterpretation of the provenance of specimens identified as S. obscurus parvidens; misunderstanding of the type locality; and inclusion of specimens of this taxon in the type series of another species with which S. obscurus parvidens has been both contrasted and allied at different times. My investigation of S. obscurus parvidens indicates that it is a distinctive population that is morphologically closest to S. ornatus, and it corresponds to the Southern Clade of that species. However, the appropriate names for deep clades within S. ornatus remain uncertain. Until this uncertainty is resolved, S. obscurus parvidens should be considered a distinctive population within S. ornatus; for conservation purposes, it should be recognized as S. ornatus parvidens.

Early Channel Island peoples often focused on large, easy-to-gather intertidal species such as California mussels (Mytilus californianus) and black abalone (Haliotis cracherodii), with later peoples expanding their shellfish economy to include a wider range of species. By the time of European contact (AD 1542-1820) the Island Chumash lived in large, sedentary villages and collected a diverse range of shellfish species by the millions. Although predation by the Chumash and their ancestors affected the size of several key shellfish species, 19th and 20th century commercial harvests targeted specific, high-value species for global markets, bringing several shellfish species (e.g., white [Haliotis sorenseni], pink [Haliotis corrugata], and black abalone) to the brink of extinction. This analysis of shellfish remains from Northern Channel Island archaeological sites tracks the changing role of shellfish in human subsistence economies from Terminal Pleistocene to Historic times. An archaeological record featuring several millennia of relative resiliency under intensive Native American predation suggests that regulated, sustainable, and productive shellfish fisheries can be maintained if balanced and healthy near-shore ecosystems are rebuilt.

As demonstrated by Sternberg et al., half of all SNe Ia with detectable Na D absorption at the host-galaxy redshift in high-resolution spectroscopy have Na D line profiles with significant blueshifted absorption relative to the strongest absorption component, which indicates that a large fraction of SN Ia progenitor systems have strong outflows. In this study, we find that SNe Ia with blueshifted circumstellar/interstellar absorption systematically have higher ejecta velocities and redder colors at maximum brightness relative to the rest of the SN Ia population. This result is robust at a 98.9%-99.8% confidence level, providing the first link between the progenitor systems and properties of the explosion. This finding is further evidence that the outflow scenario is the correct interpretation of the blueshifted Na D absorption, adding additional confirmation that some SNe Ia are produced from a single-degenerate progenitor channel. An additional implication is that either SN Ia progenitor systems have highly asymmetric outflows that are also aligned with the SN explosion or SNe Ia come from a variety of progenitor systems where SNe Ia from systems with strong outflows tend to have more kinetic energy per unit mass than those from systems with weak or no outflows.

In this paper, we present the first installment of the PHAT stellar cluster catalog. When completed, the PHAT cluster catalog will be among the largest and most comprehensive surveys of resolved star clusters in any galaxy. The exquisite spatial resolution achieved with HST has allowed us to identify hundreds of new clusters that were previously inaccessible with existing ground-based surveys. We identify 601 clusters in the Year 1 sample, representing more than a factor of four increase over previous catalogs within the current survey area (390 arcmin (super 2) ). This work presents results derived from the first approximately 25% of the survey data; we estimate that the final sample will include approximately 2500 clusters. For the Year 1 objects, we present a catalog with positions, radii, and six-band integrated photometry. Along with a general characterization of the cluster luminosities and colors, we discuss the cluster luminosity function, the cluster size distributions, and highlight a number of individually interesting clusters found in the Year 1 search.

We further present millimeter and radio data obtained with the Submillimeter Array, the Combined Array for Research in Millimeter-wave Astronomy, and the Expanded Very Large Array during the first three weeks after explosion. Combining these observations with early optical photometry, we show that the panchromatic data set is well described by non-thermal synchrotron emission (radio/mm) with inverse Compton scattering (X-ray) of a thermal population of optical photons. In this scenario, the shock partition fractions deviate from equipartition by a factor, (epsilon (sub e ) /epsilon (sub B ) ) approximately 30. We derive the properties of the shock wave and the circumstellar environment and find a time-averaged shock velocity of (sub IMG .../ (super and a progenitor mass-loss rate of (sub IMG .../ (super (for an assumed wind velocity, v (sub w) = 1000 km s (super -1) ). We show that these properties are consistent with the sub-class of Type IIb SNe characterized by compact progenitors (Type cIIb) and dissimilar from those with extended progenitors (Type eIIb). Furthermore, we consider the early optical emission in the context of a cooling envelope model to estimate a progenitor radius of R (sub *) nearly equal 10 (super 11) cm, in line with the expectations for a Type cIIb SN. Together, these diagnostics are difficult to reconcile with the extended radius of the putative yellow supergiant progenitor star identified in archival Hubble Space Telescope observations, unless the stellar density profile is unusual. Finally, we searched for the high-energy shock breakout pulse using X-ray and gamma-ray observations obtained during the purported explosion date range. Based on the compact radius of the progenitor, we estimate that the shock breakout pulse was detectable with current instruments but likely missed due to their limited temporal/spatial coverage. Future all-sky missions will regularly detect shock breakout emission from compact SN progenitors enabling prompt follow-up observations with sensitive multi-wavelength facilities.

AN - 1143498666; 649541-9 AB - Detailed analysis of the substructure of Lyalpha nebulae can put important constraints on the physical mechanisms at work and the properties of galaxies forming within them. Using high-resolution Hubble Space Telescope (HST) imaging of a Lyalpha nebula at z nearly equal 2.656, we have taken a census of the compact galaxies in the vicinity, used optical/near-infrared colors to select system members, and put constraints on the morphology of the spatially extended emission. The system is characterized by (1) a population of compact, low-luminosity ( approximately 0.1 L*) sources-17 primarily young, small (R (sub e) nearly equal 1-2 kpc), disky galaxies including an obscured active galactic nucleus-that are all substantially offset (> or =20 kpc) from the line-emitting nebula; (2) the lack of a central galaxy at or near the peak of the Lyalpha emission; and (3) several nearly coincident, spatially extended emission components-Lyalpha , He II, and UV continuum-that are extremely smooth. These morphological findings are difficult to reconcile with theoretical models that invoke outflows, cold flows, or resonant scattering, suggesting that while all of these physical phenomena may be occurring, they are not sufficient to explain the powering and large extent of Lyalpha nebulae. In addition, although the compact galaxies within the system are irrelevant as power sources, the region is significantly overdense relative to the field galaxy population (by at least a factor of four). These observations provide the first estimate of the luminosity function of galaxies within an individual Lyalpha nebula system and suggest that large Lyalpha nebulae may be the seeds of galaxy groups or low-mass clusters.

Our two primary targets are optically faint, dust-obscured galaxies (DOGs) found to lie within 2 Mpc of the centers of two massive (>10 (super 14) M (sub �) ) galaxy clusters. CO line emission is not detected in either DOG. We calculate 3sigma upper limits to the CO J = 2-1 line luminosities, L' (sub CO) < 6.08 X 10 (super 9) and <6.63 X 10 (super 9) K km s (super -1) pc (super 2) . Assuming a CO-to-H (sub 2) conversion factor derived for ultraluminous infrared galaxies in the local universe, this translates to limits on the cold molecular gas mass of (sub IMG .../ (super and (sub IMG .../ (super . Both DOGs exhibit mid-infrared continuum emission that follows a power law, suggesting that an active galactic nucleus (AGN) contributes to the dust heating. As such, estimates of the star formation efficiencies in these DOGs are uncertain. A third cluster member with an infrared luminosity, L (sub IR) < 7.4 X 10 (super 11) L (sub �) , is serendipitously detected in CO J = 2-1 line emission in the field of one of the DOGs located roughly two virial radii away from the cluster center. The optical spectrum of this object suggests that it is likely an obscured AGN, and the measured CO line luminosity is L' (sub CO) = (1.94 + or - 0.35) X 10 (super 10) K km s (super -1) pc (super 2) , which leads to an estimated cold molecular gas mass (sub IMG .../ (super . A significant reservoir of molecular gas in a z approximately 1 galaxy located away from the cluster center demonstrates that the fuel can exist to drive an increase in star formation and AGN activity at the outskirts of high-redshift clusters.

Based primarily on Eumaeini in the Anderson and Sullivan Collections (Smithsonian Institution), we treat 149 thecline species recorded from Nicaragua with their localities and months of capture. None are endemic to Nicaragua, but 15 species have the northern or southern limit of their known distribution in Nicaragua. We relate the distributions of these 15 species, many of which are figured, to the life zones and physical features of Nicaragua and adjoining countries. Those eumaeine names for which Nicaragua is a type locality are noted, and a few unresolved taxonomic problems among the Nicaraguan fauna are pointed out. We list another 73 hairstreak species that are recorded both to the northwest and southeast of Nicaragua, but not in Nicaragua. Finally, we present brief historical comments on the collectors of Nicaraguan hairstreaks.

Under the standard assumption of optically thin single temperature (T) sources, the dust SED as represented by a power-law-modified blackbody is subject to a strong degeneracy between T and the spectral index beta . The traditional non-hierarchical approaches, typically based on chi super(2) minimization, are severely limited by this degeneracy, as it produces an artificial anti-correlation between T and beta even with modest levels of observational noise. The hierarchical Bayesian method rigorously and self-consistently treats measurement uncertainties, including calibration and noise, resulting in more precise SED fits. As a result, the Bayesian fits do not produce any spurious anti-correlations between the SED parameters due to measurement uncertainty. We demonstrate that the Bayesian method is substantially more accurate than the chi super(2) fit in recovering the SED parameters, as well as the correlations between them. As an illustration, we apply our method to Herschel and submillimeter ground-based observations of the star-forming Bok globule CB244. This source is a small, nearby molecular cloud containing a single low-mass protostar and a starless core. We find that T and beta are weakly positively correlated-in contradiction with the chi super(2) fits, which indicate a T- beta anti-correlation from the same data set. Additionally, in comparison to the chi super(2) fits the Bayesian SED parameter estimates exhibit a reduced range in values.

We evaluated localities hypothesized as ice-free areas or glacial refugia in other Arctic vertebrates using molecular data from 11 microsatellite loci, mitochondrial DNA (mtDNA) control region, and six nuclear introns for 32 populations across the Holarctic. Moderate levels of genetic structure were observed for microsatellites (F sub(ST)= 0.129), introns ( Phi sub(ST)= 0.185), and mtDNA control region ( Phi sub(ST)= 0.461), with among-group variation maximized when populations were grouped based on subspecific classification. Two haplotype and at least two allele groups were observed across all loci. However, no haplotype/allele group was composed solely of individuals of a single species, a pattern consistent with recent divergence. Furthermore, northernmost populations were not well differentiated and among-group variation was maximized when L. argentatus and L. hyberboreus populations were grouped by locality rather than species, indicating recent hybridization. Four populations are located in putative Pleistocene glacial refugia and had larger tau estimates than the other 28 populations. However, we were unable to substantiate these putative refugia using coalescent theory, as all populations had genetic signatures of stability based on mtDNA. The extent of haplotype and allele sharing among Arctic white-headed gull species is noteworthy. Studies of other Arctic taxa have generally revealed species-specific clusters as well as genetic structure within species, usually correlated with geography. Aspects of white-headed gull behavioral biology, such as colonization ability and propensity to hybridize, as well as their recent evolutionary history, have likely played a large role in the limited genetic structure observed. Concordance in haplotype and allele groups suggests that white-headed gulls were subdivided into at least two refugia that persisted for extended periods of time during the Pleistocene. However, we were unable to substantiate these putative refugia using coalescent theory. The strong tendency for hybridization in this group erased the genetic signature of Pleistocene refugia.

The plant comprises a regularly-bifurcating flat ecostate multilayered thallus with entire margins. Following comparisons of this fossil with gametophytes of extant and fossil liverworts, a new genus Riccardiothallus was established in the family Aneuraceae (Jungermanniopsida). The fossil, which appears to be closely similar to several members of the extant genus Riccardia, is the earliest unequivocal megafossil evidence of a liverwort. Considering the sedimentary environment of Riccardiothallus devonicus and the habitats of many extant Riccardia species, we conclude that Riccardiothallus devonicus probably lived in a warm and humid riverine environment. The age (Pragian, 407-411 Ma) of Riccardiothallus devonicus suggests that the differentiation of Jungermanniopsida and Metzgeriidae was in the Early Devonian, significantly earlier than the assumptions derived from analyses of chloroplast DNA sequences of modern liverworts and current total evidence phylogenies (Late Devonian, 359-385 Ma; Late Carboniferous, 299-307 Ma).

This study links pollen characters with the taxonomic divisions of the genus alder based on nrDNA ITS sequence data. The value of the study is in the breadth of the taxonomic coverage of the three subgenera, as the samples per species only range from 1 to 6. From 29 Alnus species, the authors studied pollen from 59 modern reference collections (prepared by acetolysis) and recorded the number and type of apertures (pores), thickness of the arci, pollen size and polar arci. Tallies of the number of pores on the pollen grains in a reference collection typically have a range of + or -1 or 2. Exceptions are presumed hybrid collections in Alnus rugosa with a range of + or -5, which have malformed pollen cells suggesting infertility. The presumed hybrids show a greater range of both pore number and size of pollen grains. The dominant pore number is a key feature that separates the subgenus Alnobetula (=Alnaster) from the other two subgenera by consistently having predominantly 5-, 6- or 7- pored pollen grains, while all other Alnus taxa sampled have pollen with predominantly 4- or 5-pored pollen. The dominant pore number is a consistent feature within the subgenus Alnobetula (10 species), but is inconsistent in 3 out of 16 species of the subgenus Alnus and within the subgenus Clethropsis (3 species). Thickenings of the pore lip, aspidate (protruding) and vestibulate pores are important features of Alnus pollen on a species level. Alnus-like pollen morphology occurs occasionally in certain other betulaceous genera (Betula and Carpinus). Differences in character or thickness of arci (band-like thickenings on the pollen wall between pores) tend to be somewhat consistent within a species and vary within subgenera. Two Alnobetula species in the Alnus viridis complex (Alnus crispa and Alnus sinuata) have arci that are weakly developed or appear as simple folds; walls are fragile and pores are typically less aspidate. Pollen sizes in different species overlap greatly, may be partly influenced by processing methods and do not seem to be generally helpful in characterizing species. Circular doughnut-shaped arci thickenings on the polar area of pollen grains are a common feature (16-40%) in two closely related East Asian taxa of subgenus Alnobetula with large pollen ("Clade A": Alnus firma and Alnus sieboldii). These "Clade A" features have been reported from Miocene collections of Alnus pollen from Alaska, and support megafossil evidence in determining the biogeography of this group along the Pacific Rim in the Neogene. The Miocene appearance of subgenus Alnobetula megafossils in both Alaska and Japan can only have occurred via a Bering Land Bridge. This relation is now confirmed by Reinink-Smith's Miocene "Clade-A-type" pollen data of Alaska. These taxa had Pacific Rim distributions, similar fruiting carposamaras and now correspond to a DNA ITS subgroup within Alnobetula. Depending on the geographic location with limited number of local alder species, certain Holocene identifications are possible based on pore structure and arci thickness, e.g. the Alnus crispa-type in eastern Canada and the Alnus sinuata-type in the Pacific northwest.

However, data concerning the population genetics and long-term demography of this bird species are lacking. In this study, we focused on three populations within the Lesser Antilles and one on Puerto Rico and assessed genetic and demographic processes, using five nuclear and two mitochondrial markers. We found that genetic diversity of bananaquits on Puerto Rico exceeds that on the smaller islands (Dominica, Guadeloupe and Grenada); this might reflect either successive founder events from Puerto Rico to Grenada, or more rapid drift in smaller populations subsequent to colonization. Population growth rate estimates showed no evidence of rapid expansion and migration was indicated only between populations from the closest islands of Dominica and Guadeloupe. Overall, our results suggest that a "demographic fission" model, considering only mutation and drift, but without migration, can be applied to these bananaquit populations in the West Indies.

During this period, there is no evidence of Panamanian magmatic arc activity to the east of the Panama Canal Basin while to the west and in localized regions to the east of the Panama Canal Basin a phase of intrusive-only activity is recorded. Fundamentally, geochemical and geochronological evidence presented herein indicate that this intrusive activity was predominantly 'adakitic-like' and becomes younger from west to east along an approximately W-E striking lineament. Granodiorites of the Petaquilla batholith, western Panama yield LAM-ICP-MS (super 206) Pb/ (super 238) U zircon ages of 29.0+0.7, -0.6 Ma, 28.5+0.7, -0.5 Ma, 28.3+0.5, -0.4 Ma and 26.2+0.5, -0.9 Ma. To the east of the Panama Canal Basin zircons from a hypabyssal diorite of the mainly intermediate Maje subvolcanic suite, cedes a mean (super 206) Pb/ (super 238) U age of 18.9+0.4 Ma. Relative to other 70-5 Ma Panamanian magmatic arc lavas and intrusives, Maje and Petaquilla intrusives yield adakitic-like major and trace element abundances (e.g., >15wt.% Al (sub 2) O3, generally >3.5 wt.% Na (sub 2) O, >400 ppm Sr, 120) and strongly fractionated HREE patterns. These 30-26 Ma (Petaquilla) and 19 Ma (Maje) suites are also compositionally similar to a subvolcanic suite of rare, circa 25 Ma adakitic-like, andesitic intrusives which occur within the Panama Canal Basin midway between Petaquilla and Maje and at the same approximate latitude as Petaquilla and Maje. Collectively, the geochemical and geochronological data for the adakitic-like intrusives arc consistent with formation via partial melting of lowermost, mafic crust above a sub-horizontal slab tear that propagated from the west (Petaquilla) to the east (Maje) between 30 and 19 Ma. Our new tectonic model postulates that collision between the Panamanian magmatic arc system and an 'indentor' (e.g., a tract of thickened buoyant, oceanic crust or plateau) occurred at about 40 Ma, a time of which coincides with the initiation of left-lateral offset of the Early (i.e., 70-40 Ma) Arc system. This collision resulted in the shutdown of the Early Arc system, possible steepening of the subducting Farallon slab and ultimately slab break-off and the phase of mainly adakitic-like intrusive activity. Subsequent to slab removal by approximately 20Ma, NE-dipping subduction jumped to the south and initiated production of the Later (i.e., post 20 Ma) Arc system soon thereafter.

However, salt-marsh ecosystems are often viewed and managed as systems controlled by physical processes, despite recent evidence for herbivore-driven die-off of marsh vegetation. Here we use field observations, experiments, and historical records at 14 sites to examine whether the recently reported die-off of northwestern Atlantic salt marshes is associated with the cascading effects of predator dynamics and intensive recreational fishing activity. We found that the localized depletion of top predators at sites accessible to recreational anglers has triggered the proliferation of herbivorous crabs, which in turn results in runaway consumption of marsh vegetation. This suggests that overfishing may be a general mechanism underlying the consumer-driven die-off of salt marshes spreading throughout the western Atlantic. Our findings support the emerging realization that consumers play a dominant role in regulating marine plant communities and can lead to ecosystem collapse when their impacts are amplified by human activities, including recreational fishing.

In this paper, I argue that rates are usefully thought of as model parameters that relate magnitudes of evolutionary divergence to elapsed time. Starting with models of directional evolution, random walks, and stasis, I derive for each a reasonable rate metric. These metrics can be linked to existing approaches in evolutionary biology, and simulations show that they can be estimated accurately at any temporal resolution via maximum likelihood, but only when that metric's underlying model is true.

However, the effectiveness of secondary seed dispersal has rarely been assessed because it is difficult to track seeds until they die or germinate. We describe a new technique that uses thread tags attached to radio transmitters (telemetric thread tags) to track long-distance multistep seed dispersal by scatter-hoarding rodents. These telemetric thread tags can be turned off with a magnet and are reactivated when the seed moves. This method allows for seed tracking with minimal cache disturbance or distance bias, over long time spans, multiple seed movements, and with few effects on animal behavior. We used telemetric thread tags to track seed dispersal of the palm tree Astrocaryum standleyanum in a Neotropical forest, and achieved near-complete recovery of dispersed seeds tracked over distances as far as 241 m. We were also able to record the recovery time and fate of cached seeds without disturbing caches. Neither the removal rate nor the dispersal distance differed between seeds with telemetric thread tags and thread-tagged seeds. We conclude that telemetric thread tags can be used to document secondary seed dispersal by scatter-hoarding animals with unprecedented efficacy and precision. Given the size of these tags relative to the size of seeds and their dispersers, this method is applicable to the majority of tree species that are secondarily dispersed by scatter-hoarding mammals.

Morphometric analyses of 21 population samples consistently disclosed cohesive patterns of craniodental differentiation that support the recognition of three species: Praomys delectorum Thomas, confined to extreme southern Malawi; P.melanotus Allen & Loveridge, found in highlands of south-western Tanzania and contiguous northern Malawi; and P.taitae Heller (including octomastis Hatt), distributed in mountains and foothills of southern Kenya and northern and central Tanzania. Populations of the P.delectorum group are patchily distributed in moist montane forest, most collecting localities falling within 1000-2400m, and their range collectively coincides with the Tanganyika-Nyasa Montane Forest Group sensu Moreau. Patterns of faunal similarity derived from distributions of 65 species of terrestrial small mammals recorded from Tanzania's highlands, including the Eastern Arc Mountains, demonstrated pronounced geographical discontinuities in montane associations but failed to uncover a prominent vicariant role for the Makambako Gap.

AN - 1021127982; 22592417 AB - Predators are often confronted with a broad diversity of potential prey. They rely on cues associated with prey quality and palatability to optimize their hunting success and to avoid consuming toxic prey. Here, we investigate a predator's ability to assess prey cues during capture, handling, and consumption when confronted with conflicting information about prey quality. We used advertisement calls of a preferred prey item (the túngara frog) to attract fringe-lipped bats, Trachops cirrhosus, then offered palatable, poisonous, and chemically manipulated anurans as prey. Advertisement calls elicited an attack response, but as bats approached, they used additional sensory cues in a sequential manner to update their information about prey size and palatability. While both palatable and poisonous small anurans were readily captured, large poisonous toads were approached but not contacted suggesting the use of echolocation for assessment of prey size at close range. Once prey was captured, bats used chemical cues to make final, post-capture decisions about whether to consume the prey. Bats dropped small, poisonous toads as well as palatable frogs coated in toad toxins either immediately or shortly after capture. Our study suggests that echolocation and chemical cues obtained at close range supplement information obtained from acoustic cues at long range. Updating information about prey quality minimizes the occurrence of costly errors and may be advantageous in tracking temporal and spatial fluctuations of prey and exploiting novel food sources. These findings emphasize the sequential, complex nature of prey assessment that may allow exploratory and flexible hunting behaviors.

It is characterized by having white to cream, small, erect colonies composed of 1-4 fronds, stems short or absent network irregular and open without fan midribs, and polyp mounds slightly raised and sparsely distributed. All sclerites are colourless. Coenenchymal sclerites mostly composed of long spindles reaching up to 0.25 mm in length, and long and thin anthocodial rods, up to 0.16 mm in length. Morphological characters are analysed and illustrated. Scanning electron microscopy was used for sclerite study. The new species is herein described and compared with other similar species reported from the eastern Pacific. Pacifigoria marviva increases the number of Pacifigorgia species to 35; 20 in Panama representing 57% of the genus in the eastern Pacific, followed by Costa Rica and Ecuador with 14 and 10 species, respectively.

For cycads, thrips are specialized pollinators. We report such a specialized pollination mode from Early Cretaceous amber of Spain, wherein four female thrips representing a genus and two species in the family Melanthripidae were covered by abundant Cycadopites pollen grains. These females bear unique ring setae interpreted as specialized structures for pollen grain collection, functionally equivalent to the hook-tipped sensilla and plumose setae on the bodies of bees. The most parsimonious explanation for this structure is parental food provisioning for larvae, indicating subsociality. This association provides direct evidence of specialized collection and transportation of pollen grains and likely gymnosperm pollination by 110-105 million years ago, possibly considerably earlier.

Previous studies in this region have shown that sea-level rise in the early to mid-Holocene, and markedly increased human land use during the past several centuries, altered vegetation in and around the lagoon. The pollen record from this study documents changes in delta vegetation that likely reflect variations in Nile flow. We suggest that Cyperaceae pollen is a sensitive marker of precipitation over the Nile headwaters and the resultant Nile flow. Decreases in Cyperaceae pollen, interpreted as a marker for diminished Nile flow, as well as the increase in relative abundance of microscopic charcoal, occurred at ca. 6000-5500, ca. 5000, ca. 4200, and ca. 3000 cal. yr B.P. (calibrated years before present). These correspond to extreme regional and global aridity events associated with a more southerly mean position of the Intertropical Convergence Zone. These changes, also recorded by other proxy studies, indicate that several marked regional drought events affected the Nile Delta region and impacted ancient Egyptian and Middle Eastern civilizations.

However, high-precision multicollector ion microprobe data for diverse CAIs from Vigarano (CV3) yield internal isochrons with a clearly resolved spread in initial (super 26) Al/ (super 27) Al, meaning that CAIs formed and were reprocessed over a much longer time span. Primitive (unmelted) CAIs have a consistent value of 5.2+ or -0.1X10 (super -5) , melted CAIs range from 5.17X10 (super -5) to 4.24X10 (super -5) , and one single object with a complex multistage history has an internal range of (super 26) Al/ (super 27) Al=(4.77-2.77)X10 (super -5) . The entire range corresponds to an age span of approximately 0.7 Ma. Thus not all CAIs formed at "time zero", and only the most primitive CAIs should be used as benchmarks for earliest Solar System chronology.

Even though both classes of terpenoids have long been recognized as plant biomarkers, their potential use as phylogenetically specific delta (super 13) C proxies remains largely unexplored. Little is known of how terpenoid abundance and carbon isotope composition vary either with plant phylogenetic position, functional group, or during synthesis. Here, we report terpenoid abundances and isotopic data for 44 tree species in 21 families, representing both angiosperms and gymnosperms, and both deciduous and evergreen leaf habits. Di- and triterpenoid abundances are significantly higher in evergreens compared to deciduous species, reflecting differences in growth strategies and increased chemical investment in longer-lived leaves. Carbon isotope abundances of terpenoid lipids are similar to leaf tissues, indicating biosynthetic isotope effects are small for both the MVA (-0.4 ppm) and MEP (-0.6 ppm) pathways. Leaf and molecular isotopic patterns for modern plants are consistent with observations of amber, resins and plant biomarkers in ancient sediments. The delta (super 13) C values of ancient diterpenoids are higher than triterpenoids by 2-5 ppm, consistent with observed isotopic differences between gymnosperms and angiosperms leaves, and support the relatively small lipid biosynthetic effects reported here. All other factors being equal, evergreen plants will dominate the abundance of terpenoids contributed to soils, sediments and ancient archives, with similar inputs estimated for angiosperm and gymnosperm trees when scaled by litter flux.

Because previous evidence suggests it might be a primitive achondrite from a known chondrite type, we have undertaken a study of the petrology, geochemistry, and formation history of the meteorite. Tafassasset is predominantly FeO-rich olivine ( nearly equal 58%) yet contains abundant Fe,Ni-metal ( nearly equal 10vol.%) and sulfide ( nearly equal 3vol.%). Other phases include high- and low-Ca pyroxene, plagioclase, chromite, and phosphate. It has a recrystallized texture, containing equigranular grains that often meet at 120 degrees triple junctions. There are no relict chondrules in the thin sections examined, although they have been reported previously. Electron microprobe analyses reveal homogeneous olivine (Fa (sub 28.6) ), both low-and high-Ca pyroxene (Fs (sub 23.6) Wo (sub 3.7) and Fs (sub 12.2) Wo (sub 39.3+ or -1) ), a range of plagioclase composition (An (sub 23-47) ), Fe,Ni-metal (with 5.3-36.6wt.% Ni and 0.1-0.8wt.% Co), troilite, chromite, and Ca-phosphate. Bulk composition analyses reveal two chips depleted in refractory lithophile and some siderophile elements compared to CI chondrites. Exceptions are enrichments in Fe, Ni and Co. A third chip is essentially chondritic in bulk composition. Different stones of the meteorite have slightly different oxygen isotope composition, yet all lie in the CR chondrite trend with one in the acapulcoite-lodranite field. Thermodynamic calculations show that Tafassasset equilibrated at a temperature above the Fe,Ni-FeS eutectic and at an oxygen fugacity of nearly equal IW-1. The texture, heterogeneous distribution of mineral phases, plagioclase composition, two-mineral closure temperatures, and bulk composition all provide evidence that Tafassasset partially melted on its parent body. A comparison with the CR chondrites, the brachinites, and two anomalous achondrites indicates that Tafassasset is most similar to ungrouped primitive achondrites Lewis Cliff (LEW) 88763 and Divnoe, and to the brachinites in overall petrography, modal mineralogy, mineral compositions, oxidation state, and bulk composition. The comparison also excludes the possibility that Tafassasset formed by partial melting of a CR chondrite. Tafassasset is a primitive achondrite and likely evolved on a parent body that experienced incomplete melting, never reached isotopic homogeneity, and was from the same oxygen isotopic reservoir as the CR chondrite parent body.

Dawn observations reveal a giant basin at Vesta's south pole, whose excavation was sufficient to produce Vesta-family asteroids (Vestoids) and HED meteorites. The spatially resolved mineralogy of the surface reflects the composition of the HED meteorites, confirming the formation of Vesta's crust by melting of a chondritic parent body. Vesta's mass, volume, and gravitational field are consistent with a core having an average radius of 107 to 113 kilometers, indicating sufficient internal melting to segregate iron. Dawn's results confirm predictions that Vesta differentiated and support its identification as the parent body of the HEDs.

The signature of deep lithologies excavated during the formation of the Rheasilvia Basin on the south pole has been preserved on the surface. Color variations (band depth, spectral slope, and eucrite-diogenite abundance) clearly correlate with distinct compositional units. Vesta displays the greatest variation of geometric albedo (0.10 to 0.67) of any asteroid yet observed. Four distinct color units are recognized that chronicle processes--including impact excavation, mass wasting, and space weathering--that shaped the asteroid's surface. Vesta's color and photometric diversity are indicative of its status as a preserved, differentiated protoplanet.

We reach rms noise levels of 1.5-2.1 mu Jy beam super(-1) at an average frequency of 6 GHz. No sources are observed at the center of any of the clusters. For a conservative set of assumptions about the properties of the accretion, we set 3[sigma] upper limits on IMBHs from 360 to 980 M sub([middot in circle]). These limits are among the most stringent obtained for any globular cluster. They add to a growing body of work that suggests either (1) IMBHs [> ~] 1000 M sub([middot in circle]) are rare in globular clusters or (2) when present, IMBHs accrete in an extraordinarily inefficient manner.

Basaltic breccias produced by the impact form the rim deposits, with stratigraphy similar to that observed at similar-sized craters on Earth. Highly localized zinc enrichments in some breccia materials suggest hydrothermal alteration of rim deposits. Gypsum-rich veins cut sedimentary rocks adjacent to the crater rim. The gypsum was precipitated from low-temperature aqueous fluids flowing upward from the ancient materials of the rim, leading temporarily to potentially habitable conditions and providing some of the waters involved in formation of the ubiquitous sulfate-rich sandstones of the Meridiani region.

Theoretical studies encounter difficulties in explaining their formation and origin. Here we propose a novel scenario for the production of planetary systems at such orbits, through the dynamical recapture of free floating planets (FFPs) in dispersing stellar clusters and stellar associations. This process is a natural extension of the recently suggested scenario for the formation of wide stellar binaries. We use N-body simulations of dispersing clusters with 10-1000 stars and comparable numbers of FFPs to study this process. We find that planets are captured into wide orbits in the typical range approximately few X 100-10 (super 6) AU and have a wide range of eccentricities (thermal distribution). Typically, 3-6 X (f (sub FFP) /1)% of all stars capture a planetary companion with such properties (where f (sub FFP) is the number of FFP per star in the birth clusters). The planetary capture efficiency is comparable to that of capture-formed stellar binaries, and shows a similar dependence on the cluster size and structure. It is almost independent of the specific planetary mass; planets as well as substellar companions of any mass can be captured. The capture efficiency decreases with increasing cluster size, and for a given cluster size it increases with the host/primary mass. We also find that more than one planet can be captured around the same host through independent consecutive captures; similarly, planets can be captured into binary systems, both in circumstellar and circumbinary orbits. We also expect planets to be captured into pre-existing planetary (and protoplanetary systems) as well as into orbits around black holes and massive white dwarfs, if these formed early enough before the cluster dispersal. In particular, stellar black holes have a high capture efficiency (>50% and 5-10 X (f (sub FFP) /1)% for capture of stars and planetary companions, respectively) due to their large mass. Finally, although rare, two FFPs or brown dwarfs can become bound and form an FFP-binary system with no stellar host. Copyright (Copyright) 2012. The American Astronomical Society.

However, we know little about their history because of a poor fossil record. Here, we augment previous studies based on fossil pollen of Panama with an investigation of eight species of endocarps and seeds from an upper Eocene locality near Tonosi on the Pacific coast of central Panama. Affinities at the family/order level include: Arecaceae, Vitaceae, Humiriaceae, Anacardiaceae, and Lamiales. Biogeographically, two of the Tonosi fossil taxa, Dracontomelon and cf. Leea, are interesting because they occur today only in lowland rainforests of the Old World. The new fossil genus Saxuva, together with cf. Leea, are the earliest evidence of Vitaceae (the grape family) in the Neotropics. The new genus Lacunofructus is the oldest record for Humiriaceae and supports the previously suggested Neotropical origin for the family. We interpret the Tonosi macroflora as a record of the vegetation which colonized land that emerged as part of the Eocene volcanic arc in southern Central America.

This taxon has also been reported from Ediacaran successions in North China and possibly in Siberia, making it a potential index fossil for interregional biostratigraphic correlation of upper Ediacaran successions. At Gaojiashan, Shaanxilithes ningqiangensis is often preserved along bedding planes of phosphate-rich silty and calcareous shale, with no evidence of vertical intrusion into adjacent beds and containing little to no carbonaceous material. Here, through detailed microstructural and microchemical investigation using a combination of analytical techniques, taphonomic details of Shaanxilithes ningqiangensis and potentially related forms are revealed, showing that these enigmatic fossils are preserved as clay molds. Together with other taphonomic features, such as abruptly bent ribbons, overlapping but not crosscutting ribbons, and co-occurring discoidal structures interpreted as disarticulated sections of the original organism, the new data suggest that Shaanxilithes ningqiangensis is a body fossil consisting of serially arranged units that are discoidal, lensoidal, or crescentic in shape. Shaanxilithes ningqiangensis is not a trace fossil as some previous researchers have suggested.

Fossil deposits that include exceptionally preserved insect assemblages are found in several different types of Lagerstatten, with their preservation in amber and in lake sediments being of greatest importance. Researchers have used a variety of approaches to study the taphonomy of insects preserved in lacustrine environments and have identified several important variables that contribute to the preservation potential of insects. A combination of insect ecology, morphology, and the depositional setting in which an insect specimen rests influence the preservation potential of insects and ultimately affect the spatial, temporal, and compositional resolution of fossil assemblages. In general, lacustrine insect assemblages experience very little spatial and temporal averaging. Compositional fidelity of assemblages tends to be low, with an overabundance of allochthonous taxa from smaller size classes. In addition, the composition of fossil insect assemblages will be biased depending on the specimen's position within a lake, dependent on both water depth and distance from shore. Focus areas for future research are outlined, as are recommendations for improving field collecting methods and statistical approaches. Finally, the benefits of conducting synthetic studies using global databases and the importance of studying unexceptional deposits are discussed.

Evidence indicates two distinct modes of burial, Type I and II assemblages, which show evidence for burial without or with seafloor disturbance, respectively. Type I assemblages suggest rapid (hours to days), but not instantaneous burial, without bottom disruption, enabling preservation of in situ behavior, including mass aggregations and molt ensembles. Most occurrences contain bedding planes in which trilobites exhibit incipient disarticulation. These assemblages were buried by cascades of flocculated sediment from hypopycnal, detached flows. Type II assemblages show well-articulated, enrolled, semi-enrolled, and outstretched trilobites in varied orientations relative to bedding. In such cases, bottom flows and seafloor disruption by storm or seismic disturbances in shallow waters suspended large amounts of flocculated muds as viscous slurries, which developed into hyperpycnal flows that entrained carcasses of trilobites and other organisms. In many cases, both Type I and II obrution was followed by additional sedimentation, geochemical zones moved upward through the sediment column, and there was little tendency to form diagenetic overprints. Alternatively, if burial was followed by an interval of sediment starvation, the sediments were bioturbated and very early diagenetic mineralization was superimposed, first, in rare cases, as mineralized soft parts in entombed carcasses, and later as pyritization of burrow linings. Development of the concretionary layers required more prolonged periods of stability of the sulfate reduction zone. Cementation of sediment shielded organism bodies from most or all effects of compaction. Thus, ironically, the best preservation of delicate remains required rapid burial, associated with mass mortality, and very low rates of background sedimentation following the event.
