They have shown seismic wave speed structure of the deep mantle in remarkable detail. However, the parameter with more direct relevance to the dynamics, composition, and mineralogy is the variations in density. Despite such interdisciplinary importance, seismological data that are conventionally used for tomography are insensitive to density variations. On the other hand, the lowest frequency data, i.e., the free oscillations or normal modes of the Earth, possess much coveted sensitivity to lateral variations in density as well as elastic parameters. For these long-period data, the gravitational restoring force is important, and leads to their dependence on three-dimensional density structure. We obtain large-scale, even-degree model of elastic moduli and density through these free oscillation data. The models of elastic moduli are consistent with those obtained through conventional seismic tomography. In contrast, the laterally heterogeneous whole mantle density model resembles little of either of the two seismic wave models. In fact, the correlation between density and seismic speeds approaches zero as the depth increases towards the core-mantle boundary, suggesting that the density model obtained by scaling seismic wave speed models for mantle flow calculations may not be valid. Near the core-mantle boundary, dense regions roughly correspond to the locations of slow shear wave anomalies, which are traditionally interpreted as mantle upwellings. In order to learn more about the density variations within the mantle, we need to turn to data that are of lower frequency than free oscillations. One such data set is the forced oscillations of the Earth such as the solid Earth tides. The gravitational forcing of the Sun and the Moon gives rise to well-known motions of the ocean and deformations of the solid Earth. The Earth's interior is perturbed by the disturbing tidal potential, therefore the tidal response of the Earth reveals a great deal about its inner structure. We explore the effects of three-dimensional variations in elastic moduli and density on tidal deformation using a finite-volume code. The calculations show that the perturbations in surface deformation is large with contributions from both elastic moduli and density heterogeneity. Furthermore, the differences in tidal signal due to changes in the input density model (scaled shear wave speed model vs. model obtained from normal-mode constraints) are clearly observed. These results suggest that the tidal deformation can be obtained through GPS measurements and that they will provide invaluable data in further constraining deep Earth's structure.

The analysis was conducted on thirty (30) coretop samples collected from the continental shelf to lower slope. A total of 7479 polycystine tests: 2933 spumellarians and 4646 nasellarians were counted. Nasellarians domain the assemblage indicating high-salinity conditions at distal setting. 15 families, 93 genera and 104 species were described. More abundant families are Plagoniidae (31%), Pyloniidae (21%), Spyridae (11%) and Spongodiscidae (10%). Among the genera Arachnocoralium, Lophophaena, Octapyle, Plagonium, Tetrapyle and Tholospyris, were the most representative, constituting the 43% of the total counting. The typical association is constituted by Tetrapyle octachantha, Plagoniidae group, Tholospyris spp., Octapyle stenozoa, Arachnocoralium calvata, Lophophaena hispida, Pterocorys minythorax and Peromelissa phalacra. The high-diversity, equity and dominance values indicate an equitable distribution of the number of individuals among the species. This, in addition to the low URI values, reflects no upwelling conditions in the study zone. From these facts it was concluded that radiolarians do not reflect upwelling conditions. These results constitute so far, the first taxonomic and ecological approach for the Colombian Caribbean area.

Hence the Foraminiferal Collections comprising Cenozoic and Mesozoic taxa were created. In addition, an electronic database with photographs groups all the specimens into categories. Collections are organised in three main divisions: Taxa, Biofacies and Regional. The first two constituted Reference Collections holding over 500 species of foraminifera, among planktonic and benthonic forms. The latter group encompasses calcareous, agglutinated and pseudochitinous specimens. They are made up of homeotypes, topotypes and a few morphotypes coming from several Colombian basins. Biofacies Collection belongs only to Colombian Caribbean slope and shelf so far. The Regional Collection comprises more than 5000 mounted micropalaeontological slides belonging to internal research projects over a period of nearly five years. It encompasses picked and/or sorted slides (and related washed residues) from well and outcrop sections in Colombia. The "Foraminifera Database" was designed to gather the exclusive information to each microslide of the catalogued material, such as locality, sample depth and age, just to mention a few. This database provides also an easy and rapid way to seek for a species, by searching through almost 600 records. Holotype descriptions and figures are available for comparison with optical and/or SEM photographs of the material contained in the Reference Collections as well. In order to keep pace with the incoming large amounts of data from diverse research projects conducted at ICP, the same database framework is being used to construct the whole inventory of microslides of the Regional Collection. For the previous reasons, we consider our collections a potential repository of new holotypes coming from further research in the area.

The aims of the study are: (1) to estimate the distribution of microorganisms at different bathymetries and kind of substrate, (2) to establish the relationship between the water column structure and water depth on the bases of the plankton distribution, (3) to understand the upwelling effect on some taxa and (4) to provide taxonomical data-bank of tropical species. On the basis of benthic foraminifera three different assemblages corresponding to three different environments were characterized: (1) association with variable percentages of porcellaneous, hyaline and agglutinated benthic foraminifera indicative of shelf environment; (2) association dominated by calcareous hyaline microfauna mainly composed by infaunal foraminifera corresponding mainly to upper bathyal suboxic marine conditions, (3) association composed by agglutinated and calcareous hyaline foraminifera characteristic of normal deep-water marine environments. Radiolaria indicate higher productivity between 300 and 1300 meter-depth. In general, radiolarian biodiversity is high throughout the bathymetry, although the shallower samples were barren owing to the kind of substrate. The increase of lower photic zone inhabitants from the coccolithophore assemblage allows us to interpret an increasing in water stratification northwestward, apparently linked with a deepest bathymetry. These results constitute the first multi-proxy approach for the Colombian Caribbean, analyzing changes in microorganisms distribution along bathymetry gradient, but also providing a complete taxonomic approach of the species present in the area at different water depths.

During this accretionary phase Earth's core formed when dense molten-metal separated from molten or partially molten silicate. Although the physical details are not well understood, it is plausible that large-scale metal-silicate equilibrium occurred during accretion, leading to an 'equilibrium model' of core formation. The siderophile element geochemistry of the modern mantle can potentially reflect the conditions of metal-silicate equilibrium within the context of this model. Previous modeling is generally consistent with metal-silicate equilibrium in a deep magma ocean. The experimental partitioning results for Ni and Co have provided the most robust geochemical evidence for high-pressure equilibration at greater than 30 GPa. Recently we have produced a large new experimental data set for W and we take advantage of that here to assess the mutual compatibility of Ni, Co and W with the equilibrium model of core formation for Earth. To do this we assess the range of core forming conditions that simultaneously satisfy the abundance of these elements in model bulk silicate Earth. We develop both linear and non-linear parameterizations to experimental partitioning data sets for each element, taking into account the effects of pressure, temperature, oxygen fugacity, and silicate and metal compositional terms. We parameterize individual data sets in isolation as well as combinations of data sets, and assess the uncertainties in the regressions. Because there are three elements and five terms in the model the system is underdetermined. However, by fixing the silicate melt to a peridotite composition and assuming a constant metal composition (e.g. pure Fe or Fe alloy of fixed composition), the model reduces to a set of three equations in three unknowns. In models based on linear parameterizations a unique solution is determined by matrix inversion, whereas a minimization technique locates the 'best' solution in non-linear models. Each parameter has associated with it a formal regression uncertainty. In any given model using selected parameterizations, we evaluate the solution space for a large number (e.g. 30,000) of iterations wherein the error in each term is independently and randomly varied. Initial results show a wide range of solutions for any given set of experimental data inputs. In several cases the preponderance of solutions lie at pressures greater than 30 GPa, but at lower oxygen fugacity than in models of bulk Earth. We also find that solutions exist directly along the liquidus of peridotite in all models tested to date.

The forced run, which includes the solar, volcanic and greenhouse gas forcing, captures the major modes of precipitation climatology comparable to those captured by the National Center for Environmental Prediction (NCEP) reanalysis. Over the past 1000 years, the simulated GMI in the forced run exhibits a significant quasi-bi-centennial oscillation. The spectrum of the GMI has pronounced peaks on 192, 107, and 74 years, which corresponds well to the significant spectral peaks from effective radiative forcing at around 192, 107, and 80 years. Further, weak GMI was found during the model Little Ice Age (1450-1850) with three weakest periods occurring around 1460, 1685, and 1800, which fell in, respectively, the Sporer Minimum, Maunder Minimum, and Dalton Minimum periods of solar activity. Conversely, strong GMI was simulated during the model Medieval Warm Period (ca. 1030-1240). The GMI tends to vary in phase with the effective solar radiative forcing (solar forcing plus volcanic forcing). The correlation coefficients between GMI and the effective solar radiative forcing is 0.78 for the 31-year smoothed series, which are higher than that directly with solar forcing (0.72) or volcanic (0.37) forcing alone. The changes in the total amount of effective shortwave radiative forcing can reinforce the thermal contrast between the continent and ocean. When effective radiative flux increases during the local summer, the magnitude of land warming is much stronger than that in the adjacent ocean, thus the thermal contrast between continent and ocean gets reinforced. This thermal contrast further enhances the pressure differences between land monsoon regions and the surrounding oceans and thus strengthens the monsoon circulation in the presence of Coriolis force and associated rainfall. As such, each regional component of the global monsoon system will intensify from the increased radiative heating and thus the composite global monsoon will be strengthened as well. The prominent upward trend in GMI occurring in the last century and the remarkably strengthening of the global monsoon in the last 30 years (1961-1990) appear unprecedented and owed possibly in part to the increase of atmospheric carbon dioxide concentration. The simulated change of GMI in the last 30 years has a spatial pattern that differs from that during the Medieval Warm Period, suggesting that global warming that arises from the increases of greenhouse gases and the input solar forcing may have different effects on the characteristics of GMI.

The species belongs to a distinctive intermediate size-class and was larger than the Cuban Macaw Ara tricolor. It is assumed to have been endemic to the West Indies, but prehistoric interisland transport of parrots by humans makes interpreting the natural distribution of the species impossible in the absence of fossils. Historical reports of macaws elsewhere in the West Indies are rendered dubious for the same reason.

Basin analysis and apatite and zircon fission-track data from west of the modern volcanic arc of the Central Cordillera reveal a Cenozoic history of tectonic inversion and orogenic propagation. Late Cretaceous to Paleocene uplift of the Central Cordillera resulted in initial foreland basin development. Subsequent bivergent tectonic inversion of the Eastern Cordillera subdivided a formerly continuous basin into the present-day Magdalena Valley basin to the west and the Llanos basin to the east. Growth strata and episodes of rapid accumulation documented by the Cenozoic foreland record of these basins, as well as the present structural configuration of the mountain range, suggest eastward transferal of the tectonic load through an initial pop-up uplift of the Eastern Cordillera during the late Eocene-early Oligocene. Limited eastward migration of the leading edge of deformation since then seems to have resulted from contractional and transpressional deformation being accommodated along pre-existing anisotropies. Furthermore, variable thickness of the pre-orogenic stratigraphy may have prevented eastward orogenic migration by modifying critical taper angles. Denudation inferred from bedrock thermochronology and gravel petrography in palynologically dated foreland deposits at the eastern margin suggest moderate exhumation rates ( approximately 0.3 mm/yr) during the late Oligocene-Miocene, followed by rapid exhumation (1-2 mm/yr) in the Pliocene. We attribute this Pliocene acceleration in exhumation to focused denudation on the windward side of the orogen, where moisture-laden winds caused an effective erosional regime, resulting in a positive feedback with tectonic processes.

Quantitative biostratigraphic techniques could improve the zonations that have been proposed for the region. We analyze the palynological information from 3500 pollen and spores species, and 5000 samples from 58 oil wells and outcrops in eastern Cordillera, Llanos Foothills and Llanos basin of Colombia to produce a zonation for the region. Two quantitative biostratigraphic techniques, namely graphic correlation and constrained optimization, were used to analyze the data. The analysis produced a probabilistic zonation that has 31 zones for the Cenozoic. Several statistical filters, including gap analysis and edge effects, were used to reduce the noise in the zonation. The zonation was also calibrated using the carbon isotope record. This palynological zonation has been successfully tested in several areas and exploratory wells.

Prior to this study, the fiery red phosphorescence of the Hope Diamond was regarded as quite rare compared to greenish-blue phosphorescence. However, our results demonstrated that virtually all blue diamonds phosphoresce at 660 nm (orange-red) but that this emission often is obscured by a concomitant luminescence at 500 nm (green-blue). Although both bands were nearly always present, the relative intensities of these emissions and their decay kinetics varied dramatically. Consequently, phosphorescence analysis provides a method to discriminate among individual blue diamonds. Treated and synthetic blue diamonds showed behavior distinct from natural stones. Temperature-dependent phosphorescence revealed that the 660 nm emission has an activation energy of 0.4 eV, close to the 0.37 eV acceptor energy for boron, suggesting that the phosphorescence is caused by donor-acceptor pair recombination.

The bonebed is well known for its marine vertebrate fossils, especially sharks and marine mammals, but has also produced a smaller number of significant land-mammal fossils. These include the musteloid Brachypsalis obliquidens; a primitive true feline cat, Pseudaelurus, cf. P. intrepidus; the huge amphicyonid or "bear-dog," Pliocyon medius; the small borophagine dog Paratomarctus cf. P. temerarius; a larger borophagine dog Aelurodon sp.; the three-toed browsing horses, Parahippus sp., and Hypohippus sp.; a distinctive grazing horse, "Merychippus" brevidontus; a tapir Miotapirus sp.; the rhinoceroses Aphelops megalodus and Teleoceras medicornutum; a generalized camel of the subfamily Miolabinae; a camel of the subfamily Aepycamelinae; the deer-like dromomercyid Bouromeryx americanus; and a gomphothere Miomastodon sp. Together, this assemblage can be correlated to middle Barstovian age assemblages found in the Barstow Formation in the Mojave Desert, the Cache Peak Fauna in the Chanac Formation to the east in the Tehachapi Mountains, the North Coalinga sites on the west side of the San Joaquin Valley near the California Coast Range, and to other Barstovian assemblages elsewhere in North America. This age agrees with previous assignments of a middle Miocene age to the Sharktooth Hill Bonebed that have been based on microfossils, mollusks, Sr-isotope dates, and magnetic stratigraphy (Chron C5Br, 15.5 Ma). The fossil land mammal assemblage in the Sharktooth Hill Local Fauna includes only medium- and large-size animals, which is probably an original bias reflective of a distant source area in the southern Sierra Nevada. The mammal assemblage is not biased among these size groups, however, being comprised predominantly of herding/grazing animals, with slightly less abundant browsing/solitary herbivores, and more rare carnivorans. The assemblage notably includes one of the earliest North American records of a true feline cat, the last record (by 4 m.y.) of the tapir Miotapirus, some of the earliest North American records of the Barstovian-indicative gomphothere Miomastodon, and well preserved examples of the dentally distinctive horse "Merychippus" brevidontus, the latter being also found in the North Coalinga Local Fauna and in the Cache Peak Fauna.

A comprehensive look into the persistency and energetics related to a Sun-climate connection must also consider the Earth's reflectance and internal land-ocean-atmosphere feedbacks as well as the modulated galactic cosmic rays. This paper covers 3 key issues related to the total (wavelength-integrated) solar irradiance (TSI). It is pointed out that the current indeterminacy of the absolute TSI values by some ten satellite radiometers leaves a large room for the fine-tuning of mean-climatology in climate models. Constraints on both the amplitude and timescale of variability of the TSI variation can be provided by observations of sun-like stars and other Earth-based archives. Finally, the climatic responses and feedbacks connected to the solar TSI forcing will be discussed and assessed in terms of its systematic and persistent effects on local and regional centers of climatic action. A solar-Arctic physical connection on multidecadal to centennial timescales involving the Arctic surface air temperature, the variable strength of the Atlantic meridional overturning circulation, the shift and modulation of the Inter-tropical Convergence Zone (ITCZ) rainbelt, and perhaps the intensity of the wind-driven subtropical and subpolar gyre circulation will be illustrated as an example.

In this study, 10 G. blacki molars demonstrating various stages of attrition were imaged using high-resolution microtomography. Three-dimensional average enamel thickness and relative enamel thickness measurements were recorded on the least worn molars within the sample (n = 2). Seven molars were also virtually sectioned through the mesial cusps and two-dimensional enamel thickness and dentine horn height measurements were recorded. Gigantopithecus has the thickest enamel of any fossil or extant primate in terms of absolute thickness. Relative (size-scaled) measures of enamel thickness, however, support a thick characterization (i.e., not `hyperthick'); G. blacki relative enamel thickness overlaps slightly with Pongo and completely with Homo. Gigantopithecus blacki dentine horns are relatively short, similar to (but shorter than) those of Pongo, which in turn are shorter than those of humans and African apes. Gigantopithecus blacki molar enamel (and to a lesser extent, that of Pongo pygmaeus) is distributed relatively evenly across the occlusal surface compared with the more complex distribution of enamel thickness in Homo sapiens. The combination of evenly distributed occlusal enamel and relatively short dentine horns in G. blacki results in a flat and low-cusped occlusal surface suitable to grinding tough or fibrous food objects. This suite of molar morphologies is also found to varying degrees in Pongo and Sivapithecus, but not in African apes and humans, and may be diagnostic of sub-family Ponginae.

Growth and development of infants is relatively rapid, and lactation is relatively short at less than 3 months. Although mean values for the proximate composition (dry matter, protein, fat and sugar) of captive common marmoset milks fall within anthropoid norms, composition is highly variable among individual samples, with concentrations of milk fat ranging from below 1 to over 10%. To examine the extent to which this variation might be a consequence of captive conditions, we collected milk samples from wild common marmosets freely living on a farm in the state of Rio de Janeiro, Brazil. The proximate composition of the milk samples was assayed using identical techniques as used for the captive marmoset milks. The composition of the milk of wild common marmosets was also variable, but tended to be lower in dry matter, fat, protein and gross energy, and higher in sugar than milks from captive animals. Interestingly, the percentage of estimated gross energy from the protein fraction of the milks was relatively constant in both wild and captive marmosets and did not differ between wild and captive animals: 1 kcal of common marmoset milk contains on average (±SEM) 0.035 ±.001 g of protein regardless of the gross energy content of the milk or whether the milk was from a wild or captive animal. In contrast, in 1 kcal of low-energy milks, the amount of sugar was significantly higher and the amount of fat significantly lower than in 1 kcal of high-energy milks. Thus, common marmoset milk exhibits axes of variability (especially fat concentration) as well as a significant stability in the relative amount of protein. Copyright John Wiley & Sons.

Maternal energy expenditure during gestation and infant development is argued to be high, but may be offset by the provisioning of offspring by females other than the mother (allonursing). Milk composition is an important component of maternal energy expenditure, but has been examined in only a small number of primate species. Here, we report on the milk composition from laboratory-housed Bolivian squirrel monkey (Saimiri boliviensis boliviensis) dams (n = 6) and allomothers (n = 2). Milk samples (n = 16) representing mid-lactation were assayed for fat, sugar, dry matter (DM), crude protein (CP), and fatty acids. Gross energy (GE) was calculated from these constituents (excepting fatty acids). The goals of this project were: (1) to provide descriptive data on milk composition of squirrel monkeys, including the range of intraspecific variation; (2) to determine if milk produced by allomothers differs from milk from dams; and (3) to compare squirrel monkey milk to that of other small New World monkeys, the callitrichines. Squirrel monkey samples averaged 4.56% fat, 3.59% CP, 6.98% sugar, 16.59% DM, and 0.91 kcal/g. The proportion of the medium chain fatty acids 8:0 and 10:0 was 40 times greater than that reported for human milk samples, and 18:1 and 18:2n-6 comprise more than 60% of total fatty acids. Milk from allomothers was lower than dams in fat, DM, and GE, which may relate to variation in maternal condition between these two groups. Excluding allomothers, milk from squirrel monkeys was higher in mean GE than captive common marmosets, but did not differ in the proportion of energy from fat, CP, and sugar relative to total GE. The consistency in energy from protein between species suggests this may be a shared-derived trait of New World monkeys. Copyright John Wiley & Sons. Reproduced with permission.

I pay close attention to the social dynamics of rural peoples' perspectives, coping strategies and inter-ethnic conflicts. Local conflicts are elucidated as an ongoing process that traverses times of war and peace. Although they are subject to manipulation by urban actors, local conflicts are also a matter of continuous negotiation and partial consensus at the grassroots. In stark contrast to this, the struggles in the ruling group are characterized by an escalating spiral of factionalism, diminishing compromises and elimination of rivals. By analysing the relationship between urban and rural actors and the role of cosmology, the article also aims to shed new light on the multiple shapes patron-client relations can assume in Africa. // ABSTRACT IN FRENCH: Cet article cherche à nous aider à mieux comprendre la violence et les conflits en Afrique de l'Ouest contemporaine en adoptant une analyse bifocale portant à la fois sur les luttes de pouvoir au sein de l'élite urbaine et sur le cadre populaire multiethnique dans le Sud de la Guinée-Bissau. Il s'intéresse de près à la dynamique sociale des perspectives, des stratégies de défense et des conflits interethniques des populations rurales. Il décrit les conflits locaux comme un processus continu qui traverse les périodes de guerre et de paix. Bien qu'ils fassent l'objet de manipulation par les acteurs urbains, les conflits locaux sont aussi une affaire de négociation continue et de consensus partial au niveau local. En revanche, les conflits observés au sein de la classe dirigeante se caractérisent par une spirale croissante de factions, de compromis moins nombreux et d'élimination des rivaux. En analysant la relation entre les acteurs urbains et ruraux et le rôle de la cosmologie, l'article cherche également à apporter un éclairage nouveau sur les formes multiples que peuvent prendre les relations patron-client en Afrique.

We compared sediment yields estimated from regional application of the USLE, the automated revised RUSLE2, and five sediment delivery ratio algorithms to measured annual average sediment delivery in 78 catchments of the Chesapeake Bay watershed. We did the same comparisons for another 23 catchments monitored by the USGS. Predictions exceeded observed sediment yields by more than 100% and were highly correlated with USLE erosion predictions (Pearson r range, 0.73-0.92; p 0.14). In a multiple regression analysis, soil erodibility, log (stream flow), basin shape (topographic relief ratio), the square-root transformed proportion of forest, and occurrence in the Appalachian Plateau province explained 55% of the observed variance in measured suspended sediment loads, but the model performed poorly (r super(2) = 0.06) at predicting loads in the 23 USGS watersheds not used in fitting the model. The use of USLE or multiple regression models to predict sediment yields is not advisable despite their present widespread application.

8183939 AB - Videotapes from manned submersibles diving in the area of the Charlie-Gibbs Fracture Zone of the Mid-Atlantic Ridge were used to investigate the distribution of fishes, large crustaceans, epifaunal and sessile organisms, and environmental features along a series of transects. Submersibles MIR 1 and MIR 2 conducted paired dives in an area of mixed sediment and rock (beginning depth ca. 3000m) and on a large pocket of abyssal-like sediments (depth ca. 4000m). In the shallower area, the submersibles passed over extremely heterogeneous terrain with a diversity of nekton, epifaunal forms and sessile forms. In the first pair of dives, MIR 1 rose along the Mid-Atlantic Ridge from 3000 to 1700m, while MIR 2 remained near the 3000m isobath. Nekton seen in these relatively shallow dives included large and small macrourids (genus Coryphaenoides), shrimp (infraorder Penaeidea), Halosauropsis macrochir, Aldrovandia sp., Antimora rostrata, and alepocephalids. The last two were more characteristic of the upper areas of the slope reached by MIR 1, as it rose along the Mid-Atlantic Ridge to depths less than 3000m. Distributions of some forms seemed associated with depth and/or the presence of hard substrate. Sessile organisms such as sponges and large cnidaria were more likely to be found in rocky areas. The second pair of dives occurred in an abyssal area and the submersibles passed over sediment-covered plains, with little relief and many fewer countable organisms and features. The most evident of these were holes, mounds, small cerianthid anemones, small macrourids and the holothurian Benthodytes sp. A few large macrourids and shrimp also were seen in these deeper dives, as well as squat lobsters (Munidopsis sp.). Sponges and larger cnidaria were mostly associated with a few small areas of rocky substrate. Holes and mounds showed distributions suggesting large-scale patterning. Over all dives, most sessile and epifaunal forms showed clumped distributions. However, large holothurians and large nekton often had distributions not significantly different from random.

Many efforts to reduce deer-vehicle collisions (DVCs) have proven unsuccessful, but deer reduction has been a primary management tool in several states. The Virginia Department of Transportation geo-located all known DVCs in Clarke County, Virginia, from August through December 2005 (n = 246) and 2006 (n = 259). We estimated harvest intensity, deer population density, amount of forest and housing development, presence of row crops, and traffic volume and speed for 228 road segments (each 500 m in length) within the county to determine which factors are correlated with increased DVCs. A step-wise general linear model indicated that deer density (range 5-47 deer/km super(2)), and deer harvest levels (range 1-18 deer/km super(2) for 9-km super(2) blocks) were not correlated with the location of DVCs. Road attributes (traffic volume and road type) and the amount of housing development were important attributes of road segments when predicting DVCs. The locations of DVCs during the rut were not markedly different from collisions outside the rut. Over the range of deer densities and harvest levels found in this rural county, there was little evidence that these factors influence the number of DVCs. Management efforts should include changing motorist behavior or road attributes.

The caenogastropod component dominates in terms of species richness and diversity of morphology, physiology, life and reproductive modes and has produced several highly speciose endemic radiations. Ancient oligotrophic lakes (e.g., Baikal, Ohrid, Tanganyika) are key hotspots of gastropod diversity; also noteworthy are a number of lower river basins (e.g., Congo, Mekong, Mobile Bay). But unlike many other invertebrates, small streams, springs and groundwater systems have produced the most speciose associations of freshwater gastropods. Despite their ecological importance in many aquatic ecosystems, understanding of even their systematics is discouragingly incomplete. The world's freshwater gastropod fauna faces unprecedented threats from habitat loss and degradation and introduced fishes and other pests. Unsustainable use of ground water, landscape modification and stock damage are destroying many streams and springs in rural/pastoral areas, and pose the most significant threats to the large diversity of narrow range endemics in springs and ground water. Despite comprising only similar to 5% of the world's gastropod fauna, freshwater gastropods account for similar to 20% of recorded mollusc extinctions. However, the status of the great majority of taxa is unknown, a situation that is exacerbated by a lack of experts and critical baseline data relating to distribution, abundance, basic life history, physiology, morphology and diet. Thus, the already considerable magnitude of extinction and high levels of threat indicated by the IUCN Red List of Threatened Species is certainly a significant underestimate.

These 8 tortoises were marked as hatchlings or within the first 2 yr of life, and their carcasses were salvaged from predator kills. Using a blind protocol, 2 skeletochronological protocols (correction-factor and ranking) provided age estimates for a set of 4 bony elements (humerus, scapula, femur, ilium) from these tortoises of known age. The age at death of the tortoises ranged from 15 to 50 yr. The most accurate protocol - ranking using the growth layers within each of the 4 elements - provided estimates from 21 to 47 yr, with the highest accuracy from the ilia. The results indicate that skeletochronological age estimation provides a reasonably accurate method for assessing the age at death of desert tortoises and, if used with a large sample of individuals, will provide a valuable tool for examining age-related mortality parameters in desert tortoise and likely in other gopher tortoises (Gopherus).

We measured blood biochemistry profiles (calcium, magnesium, sodium, lactate dehydrogenase (LDH), urea, cholesterol, triglycerides, and glucose) of green turtles (Chelonia mydas) in Moreton and Shoalwater Bays, Australia, and compared them in relation to capture site, age, sex and exposure to harmful algal blooms of the toxic cyanobacteria Lyngbya majuscula. Turtles were considered to be clinically healthy when no external injuries or lesions were observed and there was no evidence of disease or emaciation. Differences in blood profiles were detected between sites, but not between age groups or sexes. Turtles that were exposed to L. majuscula generally had lower plasma glucose concentrations and decreased LDH activity, which may represent a metabolic downregulation resulting from food limitation. This study provides the first blood biochemistry reference values for green turtles in Queensland, Australia, that can be used in future assessments of green turtles in these foraging habitats.

It grows epiphytically on seagrass and macroalgae, which also form the basis of the diet of the herbivorous green turtle (Chelonia mydas). This toxic cyanobacterium has been observed growing in regions where turtles suffer from fibropapillomatosis (FP), a potentially fatal neoplastic disease. The purpose of this study was to determine whether green turtles consume L. majuscula in Queensland, Australia and the Hawaiian Islands, USA, resulting in potential exposure to tumour promoting compounds produced by this cyanobacterium. L. majuscula was present, though not in bloom, at nine sites examined and LA and DAT were detected in variable concentrations both within and between sites. Although common in green turtle diets, L. majuscula was found to contribute less than 2% of total dietary intake, indicating that turtles may be exposed to low concentrations of tumour promoting compounds during non-bloom conditions. Tissue collected from dead green turtles in Moreton Bay tested positive for LA. An estimated dose, based on dietary intake and average toxin concentration at each site, showed a positive correlation for LA with the proportion of the population observed with external FP lesions. No such relationship was observed for DAT. This does not necessarily demonstrate a cause and effect relationship, but does suggest that naturally produced compounds should be considered in the aetiology of marine turtle FP.

Its emergence affected current flow, salinity, temperature, and primary productivity of the Pacific and the Atlantic and launched marine organisms of the two oceans into independent evolutionary trajectories. Those that did not go extinct have diverged. As no vicariant event is better dated than the isthmus, molecular divergence between species pairs on its two coasts is of interest. A total of 38 regions of DNA have been sequenced in 9 clades of echinoids, 38 of crustaceans, 42 of fishes, and 26 of molluscs with amphi-isthmian subclades. Of these, 34 are likely to have been separated at the final stages of Isthmus completion, 73 split earlier and 8 maintained post-closure genetic contact. Reproductive isolation has developed between several isolates, but is complete in only the sea urchin Diadema. Adaptive divergence can be seen in life history parameters. Lower primary productivity in the Caribbean has led to the evolution of higher levels of maternal provisioning in marine invertebrates.

Ecologically, this work underscores the crucial role that fig fruits play in sustaining and shaping tropical frugivore communities. More generally, this work addresses several key issues in evolutionary ecology, including evolution of breeding systems (shifts between monoecy and dioecy), factors that promote the stability of mutualisms, precision of adaptation, and trajectories of community assembly and coevolution in systems with multiple interacting partners. Moreover, both the pollinating and nonpollinating wasps associated with figs provide unparalleled opportunities for examining how different population structures can differentially affect sex allocation, kin selection, the evolution of parasite virulence, and many fundamental parameters of population genetics (e.g., levels of genetic variation and rates of silent and nonsilent base substitutions).

We examined the fouling community in Alaska for the presence of the marine amphipod Caprella mutica, which is native to the northwestern Pacific Ocean and has invaded many different global regions. Between 2000 and 2007, fouling panels were deployed in 6 sheltered, shallow bays in Alaska. C. mutica were detected on panels at 4 of these bays, ranging from southeastern Alaska (Ketchikan) to the Aleutian Islands (Dutch Harbor), and have been present in Alaska for at least 6 yr. This appears to be the first reported occurrence of a non-native marine species in the Aleutians and also the first confirmation that a non-native crustacean has established self-sustaining populations in Alaska. These data contribute to growing evidence that coastlines in Alaska are susceptible to biological invasions.

The remains were recovered mostly from ca. 170-260 cm below the current land surface in marl overlain by peat and peaty marl. The stratigraphy of the site indicates that the remains were deposited in a small, open-water pond that subsequently filled. The skeleton, which is 41-48% complete, is that of a mature female, ca. 30-34 y old at death based on dental eruption and wear. Postcranial bone measurements indicate that this individual was relatively large for a female. Radiocarbon dating of wood from under the pelvis of the mastodon provided a maximum date of 12,575 plus or minus 260 14C y BP [15,550-13,850 cal y BP] for the animal, which is up to 2575 14C y before the species is believed to have become extinct. Pollen samples from the site corroborate the interpretation that the regional climate was cooler and more humid than at present and supported a mixed spruce-deciduous parkland assemblage. The relatively small size of the molars of this and other mastodons from Indiana supports the hypothesis that late-glacial mastodons-just prior to their extinction-were smaller in size relative to earlier, full-glacial conspecifics. The relationship between molar size and body size is not clear, however, and there may be geographical factors as well as a temporal influence to size variation in these animals.

There is much to be discovered about the interactions between coral animals and the microbial community, and researchers at the Smithsonian Marine Station at Fort Pierce (SMSFP) are looking for answers by investigating the early life stages of two Caribbean corals, Porites astreoides and Acropora palmata. Coral microbiology provides an exceptional framework for teaching fundamental scientific concepts, but because this research is still in its infancy, it is rarely accessible for discussion in the classroom. SMSFP researchers and educators collaborated to develop an interactive teacher workshop based on that framework. The workshop aCoral Reefs: Bacterial Worldsa presents new perspectives on teaching the concept of symbiosis, draws on examples of marine animal-bacterial symbioses to discuss the evolution of complex life, and introduces microscopy, DNA extraction, and PCR and DNA sequencing, which are used at SMSFP to investigate microbiology and symbiosis in the marine environment. Here I present current coral-bacterial research and highlight key messages of the teacher workshop. JF - [np]. 2008.

We will present a cross-system compilation of the main drivers of net mercury methylation a mercury concentration, sulfate, sulfide, general microbial activity and organic matter - on the MeHg content of sediments and wetland soils. A general model for the control of net Hg methylation in surfaces sediments and wetland soils will be presented that includes microbial activity and sediment geochemistry. Data to be presented will include new information from high sulfate and sulfide coastal sediments and soils in Chesapeake Bay and the mid-Atlantic continental shelf and slope. By compiling these data, we can begin to predict the magnitude of net MeHg production across different aquatic ecosystems, and the sensitivity of different types of ecosystems to changing mercury inputs.

LUCIE ESTUARY AND THE SOUTHERN INDIAN RIVER LAGOON, EASTERN FLORIDA, ELUCIDATED THROUGH MACROBENTHIC MONITORING AN - 19328558; 8626302 AB - Benthic infauna are important indicators of aquatic environmental quality and are used in many monitoring programs to assess overall estuarine health and to follow long-term trends in estuarine communities related to anthropogenic impacts. Soft-bottom macrofauna have been monitored quarterly since February 2005 from 13 sites in the St. Lucie Estuary (SLE) and the Indian River Lagoon (IRL). Frequent discharges of nutrient rich freshwater from the C-44 Canal (Lake Okeechobee) have contributed to very poor environmental conditions in large parts of the SLE, with an infaunal community dominated by a few opportunistic (r-strategic) species. However, the diversity and abundance of the benthic community improve significantly further downstream toward the St. Lucie Inlet. Under the Comprehensive Everglades Restoration Plan (CERP), managed freshwater inputs and decreased sedimentation in the SLE are expected to improve the environmental conditions in the entire SLE. The data clearly indicate that the benthic communities respond quickly to environmental changes and that they reflect changes in discrete zones within the studied areas in the SLE and IRL.

On two Caribbean reefs we show that some common reef algae (but not all) use chemical defenses to deter reef fishes. In Belize, the sea urchin Diadema antillarum was less discriminating than reef fishes and consumed some of almost all species of algae offered to them. For example, fish were strongly deterred by some brown algal extracts, while the urchins readily consumed them. Herbivorous reef fishes and D. antillarum have different algal preferences (often driven by chemical defenses) and can have differential effects on algal community composition. Algal natural products also mediate competitive interactions with scleractinian coral larvae. Some species of Lyngbya and Dictyota as well as extracts of some of these species caused either recruitment inhibition or avoidance behavior in coral larvae. Natural products protect some algae from herbivory (allowing increased space occupation) and reduce coral recruitment, both of which may perpetuate a aphase shifta from coral to algal dominated communities.

AND RECOVERY (SLOW TO UNDETECTABLE) AN - 19326361; 8626173 AB - Nutrient loads to the Chesapeake and its primary tributaries have increased over the past 200 years, resulting in eutrophic conditions throughout the mainstem of the Bay and some of the lower reaches of its principal tributaries. Analyses of long-term records for discharge, nutrient loads, land use, and plankton responses suggest substantial temporal and spatial expansion of the spring diatom bloom and associated bottom water hypoxia and anoxia. Nutrient reduction strategies in the basin have resulted in modest reductions in nutrient loads for some systems, but limited detectable plankton responses. Phytoplankton biomass and productivity remain high, with phytoplankton blooms observed in all seasons, driven by local/regional meteorology and accompanying responsive circulation. aResiliencea of the plankton community is best depicted in recurrent annual patterns of eutrophic assemblages and productivity with arecoverya to a new state unlikely unless nutrient loads are dramatically reduced, far beyond the small reductions implemented in the Bayas watershed in the last 25 years. Implications of these conclusions, relative to projected population growth and climate change, suggest that arecoverya will remain ever more elusive in the current century. JF - [np]. 2008.

More recent studies include phytoplankton species identifications, light saturation curves, and nutrient concentrations. For some parameters, such as light-saturated photosynthetic rate normalized to chlorophyll, interannual differences are as large as seasonal differences. The main factor governing interannual variability in annual primary production is the presence or absence of extraordinary spring blooms of the dinoflagellate, Prorocentrum minimum. In years with extraordinary blooms, primary production peaks in spring with the high biomass of P. minimum, in contrast with the main stem Chesapeake Bay, where primary productivity always peaks in summer. Long-term trends in summertime phytoplankton chlorophyll have not been observed, though temporary directional trends related to precipitation patterns have sometimes persisted for a decade before reversing. Currently there appears to be a trend toward reduced water clarity and increased chlorophyll during winter, though the cause is not presently known. These observations underscore the need for multi-decadal observations to document trends and anthropogenic impacts in coastal systems. JF - [np]. 2008.

The success rate for NSF proposals has dropped from 30% to 20% over the past six years. Mission agencies have cut back on the basic research component of their research funding portfolio. Given the high operations and maintenance costs for the large NSF ocean infrastructure programs such as the International Ocean Drilling Program and the Ocean Observatories Initiative and demands to fund the science for these programs, there will be increased pressure on the funding of small projects. New approaches for funding ocean science are needed. An increased need for funds from private sources and industry will require acceptance of focused initiatives. New models such as the large BP grant to University of California at Berkeley and the Exxon/Mobil grant to Stanford University are examples of this new paradigm. A discussion of these issues with some new approaches for university partnering in seeking private funds will be presented. JF - [np]. 2008.

They are extremely prolific producers of biologically active secondary metabolites, many of which deter grazing by generalist herbivores. Nuisance blooms of Lyngbya occur regularly throughout Florida and may be triggered by terrigenous nutrient inputs. In addition, these blooms may grow unchecked as grazers avoid consuming the filaments. In this study we examine the ecology of Lyngbya blooms in Florida including the effects of nutrient additions and light on Lyngbya growth and toxin production. We use a bioassay approach to assess the role of nitrogen, phosphorus, iron and low light conditions on the growth and secondary metabolite production of Lyngbya spp. from Florida, USA. We also assess how these compounds affect potential grazers and the implications of these blooms for the marine ecosystem. JF - [np]. 2008.

Bacterial communities in planula larvae of the Caribbean corals Porites astreoides and Favia fragum were characterized in this study. Molecular techniques were used to identify microbes associated with larvae, and sequence-specific oligonucleotide primers were designed to survey multiple samples for the presence of particular bacterial species. Fluorescence in situ hybridization (FISH) and microscopy were used to localize particular species within the larvae and determine relative abundance of certain groups of bacteria. In contrast, gamete bundles from the mass-spawning corals Montastrea spp. and Acropora spp. did not contain bacteria or archaea. This study reveals new insight into mechanisms by which reef-building corals maintain specific microbial assemblages during embryogenesis and early development. In addition, these results present the possibility for a bacterial role in larval ecology of some coral species. JF - [np]. 2008.

In this study, we examine the function of allelopathy (chemical inhibition) in mediating the interactions between chemically rich species of cyanobacteria and different life history stages of the coral Porites astreoides. Extracts and isolated compounds (microcolins A and B, curacin D) from Lyngbya spp. negatively influenced the settlement and metamorphosis of P. astreoides larvae. On reefs experiencing increased abundance of benthic cyanobacteria, the restocking of adult coral populations may be slowed due to recruitment inhibition caused by cyanobacterial natural products.

Warming can enhance repair of UV damage, especially important when the UV to temperature ratio is high in the early spring. We manipulated temperature and UV exposure of natural microbial assemblages from Lake Giles, PA during April when surface temperature is rapidly increasing. Biological weighting functions for UV inhibition of photosynthesis and bacterial incorporation of leucine were estimated based on polychromatic exposures to filtered xenon lamp irradiance. At the initial temperature (5.5ADGC), surface UV strongly inhibited photosynthesis, suppressing production. Short-term (hours) and long term (10 days) warming in the absence of UV decreased sensitivity to UVA. However, under long-term exposure to UV, lower temperatures resulted in less sensitivity due to greater acclimation and selection for resistant species (see also Jeffrey et al. presentation). Leucine incorporation was less sensitive initially, but otherwise exhibited similar trends as photosynthesis. The results show that the UV-temperature environment in early spring can affect both microbial processes and food web structure. JF - [np]. 2008.

The assay was specific to egg tissue, with no demonstrable reactivity with juvenile or male tissues. The concentration of mb-HSP70 increased as the female gonads matured, necessitating the determination of a calibration curve for future experiments. The number of eggs in females was positively correlated with body mass index (BMI), and clams with a BMI <1.4 did not produce eggs. The estimated number of eggs per clam during the fall spawning period was similar to that observed in eastern North Atlantic populations in clams of similar size; clams with shell lengths from 16 to 18 mm had from 7000 to 60000 eggs apiece. Larger clams had up to 450000 eggs. This assay effectively quantifies eggs at any stage of gonadal development in which eggs can be distinguished microscopically and is easier and cheaper to perform than other techniques of comparable precision.

Colloid distribution has been observed to change systematically with the phase of phytoplankton blooms in the Damariscotta River Estuary, implying a relationship between colloid size distribution and bloom dynamics. The purpose of this study was to monitor colloidal dynamics on a multi-year time scale in order to ascertain the relative and absolute changes in the contributions of these fractions and examine additional processes that may control their cycling. Principal component analysis was applied to EEMS results to examine statistical shifts in bulk and colloidal CDOM variability relative to such factors as photodegradation, phytoplankton bloom dynamics, precipitation events and tide. We predict that understanding colloidal variability will be key for achieving predictive insights to marine CDOM behavior. JF - [np]. 2008.

The basis bears two endites, and the ramus is an endopod bearing up to five segments. This interpretation is based on protopodal patterning from the point where the limb articulates with the body, and the assumption that this patterning should result in a derivable enditic configuration on the protopod of the serially homologous limbs maxilla 1 anteriorly and maxilliped posteriorly. Processes that affect the morphological diversity of maxilla 2 among copepods include: truncation of protopodal segmentation, suppression of enditic extension, truncation of endopodal segmentation, and segment elongation. Hypotheses about transformations of the basis suggest the following synapomorphies: neither endite of the basis is attenuate on maxilla 2 of Poecilostomatoida; the basis of maxilla 2 of Siphonostomatoida is elongate ventrally.

Optimum conditions for the quantification of soil organic phosphorus and characterization of its composition by solution (super 31) P NMR spectroscopy involved extraction in a solution containing 0.25 M NaOH and 50 mM Na 2 EDTA in a 1:20 solid to solution ratio for 4 hours at ambient laboratory T. Replicate analyses yielded a variation coefficient of 3% for organic phosphorus as a proportion of the spectral area. There was no significant difference in total phosphorus extraction from fresh and air-dried soil, although slightly more organic phosphorus and less paramagnetic ions were extracted from dried soil. The procedure was not improved by changing the concentration of NaOH or EDTA, extraction time, or solid to solution ratio. Pre-extraction with HCl or Na (sub 2) EDTA did not increase subsequent organic phosphorus extraction in NaOH-EDTA or improve spectral resolution in solution (super 31) P NMR spectroscopy. Post-extraction treatment with Chelex resin did not improve spectral resolution, but removed small concentrations of phosphorus from the extracts. Increasing the pH of NaOH-EDTA extracts (up to 1.0 M NaOH) increased the concentration of phosphate monoesters, but decreased DNA to an undetectable level, indicating its hydrolysis in strong alkali. The standardized NaOH-EDTA extraction procedure is recommended for the analysis of organic phosphorus in tropical forest soils.

In this paper, 61 species of Stenocercus are recognized, including one resurrected as S. angulifer. Morphologically, S. angulifer more closely resembles S. aculeatus. For each species, a diagnosis, description, and summary of distribution are provided based on examination of 2001 specimens and data from the literature. Notes on color in life and natural history are included for most species. Additionally, a dichotomous key to assist in the identification of specimens is provided.

The genera Cotonopsis Olsson, 1942 and Cosmioconcha Dall, 1913 are part of the so called Strombina group, and as such have been used as models to study patterns of speciation and extinction brought about by the rise of the Central American gateway. Earlier work, based on a few species of each genus, pointed towards a very close relationship of these genera, which prompted a complete dadistic analysis, including all species of both genera to evaluate the level of relationship. Cladistic analyses based on shell morphology support the monophyly of the group composed by Cotonopsis + Cosmioconcha. Cotonopsis as currently defined is paraphyletic and includes Cosmioconcha. Cotonopsis (Turrina) keeps its constituency and may retain its subgeneric status. Cotonopsis sensu stricto should be redefined to include part of Cosmioconcha. Cosmioconcha should be subdivided into two groups. One of these groups should be included in Cotonopsis sensu stricto. The second group should be given subgeneric status. Cotonopsis has a much earlier time of origination and most probably derives from Cosmioconcha. Obtained results give support to some of the evolutionary patterns documented earlier for the Neogene molluscan faunas of tropical America and contribute to a better understanding of the Plio-Pleistocene divergence and turnover events related to the rise of the Panamanian land bridge.

Fragmentation reduces the size of habitat patches, so examining the effect of patch size on community structure can provide insight into the potential effects of fragmentation. In this study, we examined the effect of habitat size on the density of Spartina alterniflora shoots in tidal saltwater marshes, as well as on the two predominant macrofaunal species, the marsh periwinkle Littoraria irrorata and fiddler crabs Uca spp. We estimated the density of shoots in three different marsh habitats, (1) large island marshes, (2) small island marshes, and (3) large fringing marshes, in Indian Field Creek, York River, Chesapeake Bay. We manipulated shoot density in each of the marsh types to distinguish between the effects of marsh grass density and marsh type on crab and Littoraria densities in the system. We found significant differences in grass density among the three marsh types as well as significant species-specific effects of grass density, marsh type, and distance from edge on faunal abundance. Decreasing the shoot density resulted in a decrease in Littoraria density in the large marshes. Littoraria density increased with distance from edge in the small marshes and in the first 5 m of the fringing marshes, then decreased with distance from edge after 5 m in the fringing marshes. Shoot density had a negative effect on crabs in both the large and small marshes. These results suggest that fragmentation would have a negative effect on the community structure by lowering the densities of both the flora and fauna.

AN - 36342961; 13070 AB - PURPOSE: The construction and operation of the National Museum of African-American History and Culture between 14th and 15th streets and Constitution Avenue and Madison Drive in Northwest Washington, District of Columbia are proposed by the Smithsonian Institution. The project would provide and operate a permanent facility on the Washington Monument Grounds within the Smithsonian Institution on a five-acre parcel. Issues addressed in selecting the site and the building design include those related to massing (the form of a building conveying proportion and size), building height, setback and alignment, outdoor program space, and the viewshed. In addition the Smithsonian Institution developed eight overarching principles that provided a foundation for the development of alternatives, guided their refinement, and served as criteria for success; these principles are related to physical character, mission and program appropriateness, monumental context, urban design principles associated with physical context, historic and cultural resource protection, visitor use and access, visitor experience, and operational functionality. This draft EIS considers seven alternatives, including a No Action Alternative, are considered in this draft EIS. Depending on the action alternative considered, the building would rise 60 to 105 feet above street level, providing for five to eight floors above grade and two to three floors below grade. The facility would contain 350,000 to 430,000 square feet. The north-south building orientation would align with the National Museum of American History's (NMAH) main building mass under three alternatives, the NMAH's north facade building mass under one alternative; and with no surrounding building under two alternatives. The east-west building orientation would align with the protecting portico of the Department of Commerce, the southwest facade of the Washington Monument, or 14th Street, or would be unaligned with respect to east-west orientation. Aesthetically, Alternative 1 would result in contextual massing the explicitly related to the pattern of buildings fronting the National Mall. Alternative 2 would be less convention in form and bridge the axis of the Mall with the north-south axis of open spaces leading to the White House. Alternative 3 would provide a more complex design, with the potential for buildings that look very different from a variety of locations. Alternative 4 would provide two distinct aesthetic experiences, blending into the landscape towards the Monument, while exhibiting more traditional building facades at the intersection of Constitution Avenue and 14th Street. Alternative 5 would provide for a bifurcated structure with varying heights, relating to context through building and spatial orientation rather than building or height alignment. Alternative 6 would offer a minimized visible mass and a soft edge along the southwest facade that would be aligned with 15th Street and Madison Drive, deferring to the presence of the Washington Monument. POSITIVE IMPACTS: The museum would be dedicated to the collection, preservation, research, and exhibition of American historical and cultural materials, reflecting the breadth and depth of the experience of individuals of African descent living in the United States. It would constitute the only institution providing a national meeting place for Americans to learn about the history and culture of African-Americans and their contributions to and relationship with every aspect of our national life. Increased visitation to the District of Columbia due to the attraction of the museum would boost the local economy. NEGATIVE IMPACTS: The museum would displace an open space on the Washington Monument grounds of the National Mall, altering the historic boundaries of the grounds and altering the spatial organization of the grounds by diminishing the prominence of the Washington Monument as a central organizing feature. Significant impacts would also occur for buildings and structures located within the Monument grounds as well as the Federal Triangle along Constitution Avenue. Vegetation and alternative land uses would be removed. The viewshed and specific vistas would be altered. The museum would be situated in an area in violation of federal standards regarding ozone and particulate matter.

Half of the Asian nations have already experienced severe (>70%) forest loss, and forest-rich countries, such as Indonesia and Malaysia, are experiencing rapid forest destruction. Both expanding human populations and industrial drivers of deforestation, such as logging and exotic-tree plantations, are important drivers of forest loss. Countries with rapid population growth and little surviving forest are also plagued by endemic corruption and low average living standards.

The Paleocene-middle Miocene foreland system of the Llanos foothills and Llanos basin of Colombia includes regional unconformities, abrupt changes in lithology/stacking patterns and flooding surfaces bounding reservoir and seal units. Here we integrate a systematic biostratigraphic study, stratal architecture and tectonic subsidence analyses, regional seismic profiles, and provenance data to define the diachronism of such surfaces and to document the direction of migration of foreland depozones. In a flexurally-deformed basin, sandstone composition, rates of accommodation and sediment supply vary across and along the basin. We show how a coeval depositional profile in the Llanos foothills-Llanos foreland basin consists of litharenites interbedded with mudstones (seal rock, supplied from the orogenic front to the west) that correlate cratonward with organic-rich mudstones and coal (source rock), and to amalgamated fluvial-estuarine quartzarenites (reservoir rock, supplied from the craton to the east) adjacent to a subaerial forebulge (unconformity). This system migrated northward and eastward during the Paleocene, westward during the early-middle Eocene, and eastward during the Oligocene. In the lower-middle Miocene succession of the Llanos basin, identification of flooding events indicates a westward encroaching of a shallow-water lacustrine system that covered an eastward-directed fluvial-deltaic system. A similar process has been documented in other basins in Venezuela and Bolivia, indicating the regional extent of such flooding event may be related to the onset of Andean-scale mountain-building processes.

These coordinated variables form a globally convergent leaf economics spectrum, which represents a general continuum running from rapid resource acquisition to maximized resource retention. Leaf economics are little studied in ancient ecosystems because they cannot be directly measured from leaf fossils. Here we use a large extant data set (65 sites; 667 species-site pairs) to develop a new, easily measured scaling relationship between petiole width and leaf mass, normalized for leaf area; this enables M (sub A) estimation for fossil leaves from petiole width and leaf area, two variables that are commonly measurable in leaf compression floras. The calibration data are restricted to woody angiosperms exclusive of monocots, but a preliminary data set (25 species) suggests that broad-leaved gymnosperms exhibit a similar scaling. Application to two well-studied, classic Eocene floras demonstrates that M (sub A) can be quantified in fossil assemblages. First, our results are consistent with predictions from paleobotanical and paleoclimatic studies of these floras. We found exclusively low-M (sub A) species from Republic (Washington, U.S.A., 49 Ma), a humid, warm-temperate flora with a strong deciduous component among the angiosperms, and a wide M (sub A) range in a seasonally dry, warm-temperate flora from the Green River Formation at Bonanza (Utah, U.S.A, 47 Ma), presumed to comprise a mix of short and long leaf life spans. Second, reconstructed M (sub A) in the fossil species is negatively correlated with levels of insect herbivory, whether measured as the proportion of leaves with insect damage, the proportion of leaf area removed by herbivores, or the diversity of insect-damage morphotypes. These correlations are consistent with herbivory observations in extant floras and they reflect fundamental trade-offs in plant-herbivore associations. Our results indicate that several key aspects of plant and plant-animal ecology can now be quantified in the fossil record and demonstrate that herbivory has helped shape the evolution of leaf structure for millions of years.

Berthierine was found in miarolitic cavities ("pockets") as aggregates of radial platy crystals with albite, as fracture-fillings in microcline and as fine-grained anhedral flakes with muscovite. Berthierine samples from all associations are depleted in Mg, but show variable enrichment in Mn. The textural relationships of the berthierine assemblage indicate that its formation is probably related to the dissolution of microcline in the presence of a low-temperature, neutral to alkaline, Fe-rich hydrothermal solution. This mode of occurrence is in direct contrast to the typical formation of berthierine in granitic pegmatites that is generally related to the alteration of cordierite-group minerals.

We examine trends through time in the distribution of low-latitude grasses (C (sub 4) plants) and forest (C (sub 3) plants) on Indo-Gangetic floodplains using carbon (delta (super 13) C) and oxygen isotopic (delta (super 18) O) values in buried soil carbonates in Siwalik Series sediments exposed in the Rohtas Anticline, north-central Pakistan. Revised, high-resolution magnetostratigraphy and a new (super 40) Ar/ (super 39) Ar date provide improved age control for the 2020 m Rohtas section. Carbon isotope results capture lateral variability of C (sub 3) versus C (sub 4) plants at five stratigraphic levels, R11 (8.0 Ma), R15 (6.74-6.78 Ma), R23 (5.78 Ma), R29 (4.8-4.9 Ma), and upper boundary tuff (UBT; 2.4 Ma), using detailed sampling of paleosols traceable laterally over hundreds of meters. Paleosols and the contained isotopic results can be assigned to three different depositional contexts within the fluvial sediments: channel fill, crevassesplay, and floodplain environments. delta (super 13) C results show that near the beginning (8.0 Ma) and after (4.0 Ma) the period of major ecological change, vegetation was homogeneously C (sub 3) or C (sub 4) , respectively, regardless of paleo-landscape position. In the intervening period, there is a wide range of values overall, with C (sub 4) grasses first invading the drier portions of the system (floodplain surfaces) and C (sub 3) plants persisting in moister settings, such as topographically lower channel swales. Although abrupt on a geologic timescale, changes in abundance of C (sub 4) plants are modest ( approximately 2% per 100,000 yr) compared to rates of vegetation turnover in response to glacial and interglacial climate changes in the Quaternary. Earlier research documented a sharply defined C (sub 3) to C (sub 4) transition in Pakistan between 8.1 and 5.0 Ma, based on vertical sampling, but this higher-resolution study reveals a more gradual transition between 8.0 and 4.5 Ma in which C (sub 3) and C (sub 4) plants occupied different subenvironments of the Siwalik alluvial plain. delta (super 18) O values as well as delta (super 13) C values of soil carbonate increase up section at Rohtas, similar to isotope trends in other paleosol records from the region. Spatially, however, there is no correlation between delta (super 13) C and delta (super 18) O values at most stratigraphic levels. This implies that the changes in soil hydrology brought about by the shift from forest to grassland (i.e., an increase in average soil evaporation) did not produce the shift through time in delta (super 18) O values. We interpret the trend toward heavier soil carbonate delta (super 18) O values as a response to changes in external climatic factors such as a net decrease in rainfall over the past 9 Ma.

Fossil woods include palms and ring-porous dicots, with smooth bark as is found in weakly seasonal tropical climates. In contrast, late Hemingfordian to early Barstovian mammals of the Cucaracha Formation are the same as those found in Nebraska, Kansas, and Florida, where climate was drier and cooler and vegetation more open. Cucaracha paleosols reconcile these differences as evidence of a mosaic of swamps to mangal (mangrove forests) preserving plants and dry uplands preserving mammals. A dozen pedotypes represent as many vegetation types, including mangrove, fresh-water and marine-influenced swamp, early successional riparian woodland, colonizing forest, dry tropical forest, and woodland. Many paleosols have calcareous nodules, and some have pedogenic barite nodules. Depth to carbonate and paleosol thickness with carbonate indicate mean annual precipitation of 573-916+ or -147 mm and mean annual range of precipitation of 27-65+ or -22 mm. Chemical analyses of paleosol Bt horizons confirm mean annual precipitation of 296-1142 mm and mean annual temperature of 15-16+ or -4.4 degrees C. Low precipitation and temperature estimates imply a rain shadow from a high (1400-4000 m) volcanic mountain range to the west, with continuous land connection to allow immigration of mammals from North America. Partial enclosure of the Caribbean Sea by a mountainous Panama peninsula, as well as by Antillean arcs, initiated high Caribbean marine temperature and salinity well before Pliocene isthmian closure.

The data are obtained by transmitting a circularly polarized pulsed waveform from the Arecibo telescope in Puerto Rico and receiving the echo in both senses of circular polarization with the Robert C. Byrd Green Bank Telescope in West Virginia. The resultant images in both polarizations have a spatial resolution as fine as 320 m 450 m near the lunar limb. The patch-focusing technique is a computationally efficient method for compensating for range migration and Doppler (azimuth) smearing over long coherence times, i.e., 983 s, which is needed to achieve the required Doppler resolution. Three to nine looks are averaged for speckle reduction and to improve the signal-to-noise ratio. At this long wavelength, the radar signal penetrates up to several tens of meters into the dry lunar surface materials, thus revealing details of the bulk loss properties and decimeter-scale rock abundance not evident in multispectral and other remote-sensing data. Application of the new radar images to the analysis of basalt flow complexes in Mare Serenitatis shows that the long-wavelength radar data are sensitive to differences in both flow age and composition, and may be particularly useful for studies of smaller deposits that do not have robust crater statistics. The new 70-cm lunar radar data are archived at the National Aeronautics and Space Administration Planetary Data System.

Taxonomic identifications were made based on derived apomorphic features preserved in the fossils. The disarticulated and sometimes fragmentary nature of the fossils themselves, combined with the relatively few apomorphic characters of vertebrae, restricted our ability to diagnose the fossils to fine-scale taxonomic levels. Identified specimens represent at least two taxa. Specimens diagnosable as members of Pythoninae are most common, but a single specimen records the presence of a colubroid snake in the fauna.

The formation, deposited approximately 6 Ma, records deposition within the second of three sequential lake basins created by tectonic and volcanic activity on the western margin of the southern Rift Valley of Kenya. These sedimentary paleobasins are exposed in the vicinity of the confluence of three rivers cutting steep cliffs into rugged, vegetated terrain. Over 1200 fossils of terrestrial vertebrates have been recovered from the site of Lemudong'o Locality 1 (LEM 1), which was formed at the edge of a shallow lake fed by slow-moving streams. Much like smaller Rift Valley lake basins in Kenya today, the Lemudong'o lake margin probably supported a mosaic of habitats ranging from closed riparian woodland to grassland and swamps. There are two fossiliferous horizons at LEM 1, clayey sands and gravels and overlying mudstones. Although the mudstones yielded the majority of the fossil material, there are significant faunal differences between the two horizons. The mudstone assemblage consists of taxa whose modern representatives primarily prefer relatively closed environments such as riparian forests, as well as many species that prefer open woodland to wooded grasslands. The sandstone assemblage samples fauna from a wider range of habitats. This contrast in taxonomic composition suggests that the mudstone and sandstone horizons sample a lakeshore environment that was varying through time. The apparent shift in habitat preferences of the fauna is consistent with the geological and geomorphological evidence for a mosaic of closed to open habitats that characterize rapidly variable rift-valley lake basins in mesic climatic regimes. One of the salient characteristics of these assemblages is the complete absence of fish, and the paucity of large mammals and reptiles, such as hippos, crocodiles, and larger bovid species that would be expected at the edge of lake basins fed by large rivers. Modern central rift-valley lake basins that are fed by small streams vary widely in size and salinity in response to climate change, and occasionally dry out completely. They do not contain fish and crocodiles, and only one has a substantial hippo population. These modern rift-valley lakes may therefore provide an analog to the depositional environment of Lemudong'o. The LEM 1 fossil assemblage is also unusual because it is dominated by small mammalian taxa, including numerous rodents, small colobine monkeys, hyracoids, and a diversity of viverrid and other carnivores. Given the lack of evidence for fluvial transport in the main fossil horizon, the biased size composition, and the significant carnivore damage on the bones, we interpret this site to represent an accumulation of carcasses by several avian and small mammalian carnivores. This paleoecological and paleogeographic reconstruction is discussed relative to penecontemporaneous fossil sites in Africa.

Three crustacean taxa are found in common with deposits of similar age and paleoenvironment of the San Rafael Formation of Colombia. Planktic foraminifera, ammonoids, inoceramid bivalves, fishes, marine reptiles, a pterosaur and plant remains were preserved in the Muzquiz quarries, in what has been interpreted as an anoxic low energy bottom at a water depth of no less than 50 m. The cirriped Stramentum preserved on the ammonite Forresteria is described. Stomatopod remains of the family Pseudosculdidae are described, their incompleteness and poor preservation prevent their detailed identification. One species of scyllarid lobster is included. An indeterminant species of nephropid lobster is also part of this assemblage. Presence of Gourretia aquilae (Rathbun) new combination, confirms correlation with the Eagle Ford Group in Texas. A systematic and morphologic review is provided for Cenomanocarcinus vanstraeleni Stenzel. a species widely distributed during Turonian times, and based on morphologic features of the abdomen and its relationship with coxae, it is assigned to the Podotremata. Also, preservation of soft tissue is reported from C. vanstraeleni and the scyllarid lobster. The raninid Cretacoranina sp. cf. C. dichrous (Stenzel) is also reported. In addition, two raninid taxa are described, their poor preservation prevents more detailed identification.

First is a biological approach that emphasizes phylogeny of extant representatives of lineages with fossil records. Second is a paleobiological approach that provides intrinsic evaluation of fossil associational evidence, of which there are several types of studies. One type of study is intensive examination of single insect-herbivore associations that involve a continuum from generalists to specialists requiring detailed autecological deductions about life habits. Another tack is assessment of herbivore damage patterns from selected plant hosts through slices of time for understanding the ecological evolution of a component community. Alternatively, comprehensive analyses can be made of the feeding patterns within a single or a series of regional floras. The record of plant-insect associations has five advantages. Associational data (1) are typically present in deposits that lack insect body fossils; (2) often surpass in abundance and usefulness insect body fossils in the same deposit; (3) frequently antedate their respective insect body fossils; (4) provide invaluable behavioral data that are unavailable from body fossils; and (5) supply crucial data for testing hypotheses in paleobiology and evolutionary biology that otherwise are unachievable. Disadvantages involve difficulties in circumscribing insect culprits, absence of extant ecological data to which fossil data can be compared, and lack of attention by paleobotanists and botanists in collecting damaged specimens. An associational view of fossil land plants and insects provides a dynamic, process-oriented view of ecosystem evolution that is needed in paleobiology.

The balance between sulfate and sulfide is key for understanding Hg methylation rates among these ecosystems. Sulfate stimulates Hg-methylating sulfate- reducing bacteria (SRB) while sulfide creates charged mercury-sulfide complexes that are unavailable for uptake by SRB. Sulfate-stimulation of methylation has been demonstrated in experimental studies that range from pure culture, to sediment and soil amendments, to large-scale field additions. Stimulation of methylation by sulfate has also been demonstrated in freshwater ecosystems impacted by sulfur pollution derived from atmospheric deposition, agriculture and mining. This presentation will present a compilation of field and laboratory studies on the impact of sulfate and sulfide on MeHg production to create a simple, general model for the control of net Hg methylation in surfaces sediments and wetland soils that includes microbial activity (sulfate reduction rate), dissolved sulfide, dissolved organic matter and and soil organic matter. In particular, the model focuses on the balance between sulfate and sulfide, and the optimal concentrations of each for methylation across studies and ecosystems. Data to be presented will include new information from high sulfate and sulfide coastal ecosystems in Chesapeake Bay. Optimal sulfate concentrations for methylation appear to range widely among ecosystems, while the optimal sulfide concentrations are more constant, and often quite low, often in the low micromolar range. However, recent data from estuarine and marine systems suggest that net methylation can proceed at somewhat higher sulfide concentrations when microbial activity is particularly high. By compiling these data, we can begin to predict the magnitude of net MeHg production across different wetland types, the sensitivity of different types of wetlands to mercury inputs, the role of wetlands in MeHg budgets for different types of aquatic ecosystems, and impact of wetland reconstructions and mitigations on MeHg budgets.

All species are illustrated with SEM of their sclerites, often with stereo pairs of the polyps. A list of the 32 valid species of Narella is given. DNA sequence analysis using the mitochondrial genes ND6 and msh1 was determined for all five species and outgroups, but little to no variation was found among the five morphospecies, consistent with the known slow rate of evolution of the mitochondrial genes in Octocorallia.

Although many marine natural products have been studied for biomedical activity, yielding important information about their biochemical effects and mechanisms of action, much less is known about ecological functions. The way in which marine consumers perceive chemical defenses can influence their health and survival and determine whether some natural products persist through a food chain. This article focuses on selected marine natural products, including okadaic acid, brevetoxins, lyngbyatoxin A, caulerpenyne, bryostatins, and isocyano terpenes, and examines their biosynthesis (sometimes by symbiotic microorganisms), mechanisms of action, and biological and ecological activity. We selected these compounds because their impacts on marine organisms and communities are some of the best-studied among marine natural products. We discuss the effects of these compounds on consumer behavior and physiology, with an emphasis on neuroecology. In addition to mediating a variety of trophic interactions, these compounds may be responsible for community-scale ecological impacts of chemically defended organisms, such as shifts in benthic and pelagic community composition. Our examples include harmful algal blooms; the invasion of the Mediterranean by Caulerpa taxifolia; overgrowth of coral reefs by chemically rich macroalgae and cyanobacteria; and invertebrate chemical defenses, including the role of microbial symbionts in compound production.

Eleven surface samples of the reef crest coral Acropora palmata from nine sites along its 15-km length plot above the western Atlantic sea-level curve from 3,000 to 4,500 cal years ago (calibrated, calendar super(14)C years). These elevated clusters suggest that the reef complex suffered extensive storm damage during this period. The constant heavy wave action typical of this area and consequent low herbivory maintain conditions favoring algal growth, thereby limiting the reestablishment of post-storm reef framework. Site descriptions and detailed line surveys show a surface now composed mainly of reworked fragments of A. palmata covered with algal turf, macroalgae and crustose coralline algae. The reef contains no live A. palmata and only a few scattered coral colonies consisting primarily of Diploria spp. and Porites astreoides, along with the hydrocoral Millepora complanata. A few in situ framework dates plot at expected depths for normal coral growth below the sea-level curve during and after the period of intense storm activity. The most recent of these in situ samples are 320 and 400 cal years old. Corals of this late period likely succumbed to high turbidity associated with land clearance for sugarcane agriculture in the mid-1600s.

To date, interactions between specific serogroups and species of plankton remain poorly understood. Laboratory microcosm experiments were carried out to compare quantitatively the colonization of two copepod species, Acartia tonsa and Eurytemora affinis, by each of the epidemic serogroups. V. cholerae O1 consistently achieved higher abundances than V. cholerae O139 in colonizing adults of each copepod species as well as the multiple life stages of E. affinis. This difference in colonization may be significant in the general predominance of V. cholerae O1 in cholera epidemics in rural Bangladesh where water supplies are taken directly from the environment.

The specificity of these interactions and associated fungal distributions could influence orchid distributions and diversity. We investigated the mycorrhizal specificity of the tropical epiphytic orchid Ionopsis utricularioides across an extensive geographical range. DNA ITS sequence variation was surveyed in both plants and mycorrhizal fungi. Phylogeographic relationships were estimated for the mycorrhizal fungi. Orchid functional outcomes were determined through in vitro seed germination and seedling growth with a broad phylogenetic representation of fungi. Most fungal isolates derived from one clade of Ceratobasidium (anamorphs assignable to Ceratorhiza), with 78% within a narrower phylogenetic group, clade B. No correlation was found between the distributions of orchid and fungal genotypes. All fungal isolates significantly enhanced seed germination, while fungi in clade B significantly enhanced seedling growth. These results show that I. utricularioides associates with a phylogenetically narrow, effective fungal clade over a broad distribution. This preference for a widespread mycorrhizae may partly explain the ample distribution and abundance of I. utricularioides and contrasts with local mycorrhizal diversification seen in some nonphotosynthetic orchids. Enhanced orchid function with a particular fungal subclade suggests mycorrhizal specificity can increase orchid fitness.

Known as Cobbler's Reef, this feature had no live colonies of A. palmata at our study sites and supported only small scattered colonies of corals, mainly Diploria spp., Porites astreoides and the hydrocoral Millepora complanata. Eleven of 29 surface-sample radiocarbon dates plot above the western Atlantic sea-level curve between approximately 3,300 to 4,500 cal yrs (calibrated, calendar super(14)C years) ago. This suggests that the reef complex was extensively damaged by a series of severe storms during this period. A reduced number of in situ framework dates follow that period and plot at acceptable depths of growth below this sea-level curve. The most recent dates are 320 and 400 cal yrs old. The lack of coral framework recovery and final demise of this reef are probably related to a number of disturbances. Although white-band disease, bleaching, and recruitment limitations could have played a role, a lack of herbivory in this area of constant heavy wave action probably allowed heavy algal growth that prevented the re-establishment of a vigorous coral reef following the period of severe storm activity. Finally, the turbidity associated with the clearing of land for sugarcane agriculture in the mid-1600s likely killed the last of the sediment-sensitive A. palmata on Cobbler's Reef. The more recent almost complete loss of A. palmata from other reefs off Barbados is probably related to storm damage and nutrient runoff and construction associated with tourism development. This is an expanded report of an earlier publication of this study, with descriptions of sampling sites and documentation of the demise of A. palmata island wide.

Studies in the 1970s and 1980s documented the rich fauna of rolled-leaf hispine beetles and their association with the Neotropical monocot family Heliconiaceae in Central America. In this report, the taxonomic breadth of these early studies is expanded to include species in the families, Marantaceae, Poaceae, Arecaceae and Costaceae, all with species occurring sympatrically with the Heliconiaceae in lowland Panama. Additionally, the analysis is widened to include open-leaf scraping and internal leaf-mining clades of hispoid Cassidinae. The censuses add more than 5080 Cassidinae herbivore occurrence records on both open and unfurled new leaf rolls of 4600 individual plants. Cluster analysis reveals that while many Hispinae species tend to group with plant species in only one of the three monocot orders, 9 of 16 Hispinae species on Zingiberales hosts were recorded in substantial numbers on both the Heliconiaceae and the Marantaceae, indicating an underlying pattern of feeding flexibility at the host plant family level.

In the mid-continental United States, Carex species are dominant in natural freshwater wetlands yet are slow to recolonize hydrologically restored wetlands. To aid in Carex revegetation efforts, we determined the dormancy breaking and temperature germination requirements of 12 Carex species. Seeds were cold stratified at 5/1 degree C for 0-6 months and then incubated in light at 5/1 degree C, 14/1 degree C, 22/8 degree C, 27/15 degree C, or 35/30 degree C. We found that all Carex species produced conditionally dormant seeds. The optimal temperature for germination for all but three species was 27/15 degree C. As is the case in other species with physiological dormancy, cold stratification increased germination percentages, broadened the temperature range suitable for germination, and increased germination rates for most species, but the magnitude of the effects varied among species. Many species germinated to 80% at 27/15 degree C without cold stratification and at 22/8 degree C with less than or equal to 1 month of stratification but required much longer stratification (up to 6 months depending on the species) to germinate to 80% at 14/1 degree C and 35/30 degree C. Our findings illustrate how a stratification pretreatment can greatly benefit Carex seed sowing efforts by triggering rapid germination to higher percentages. We recommend that cold stratification be targeted towards species with strong dormancy or used across a wider range of species when seed supplies for restoration are limiting. For Carex revegetation, establishing Carex canopies rapidly may help to prevent the invasion of undesirable species such as Phalaris arundinacea.

The fossil material is composed of an epiplastron, a hypoplastron, a peripheral, two costals, and a neural bone, which suggest an affinity to the Kinosterninae subfamily based upon the absence of an entoplastron and an abdominal scale. The presence of a hinge in the anterior and posterior plastral lobe and a large epiplastron longer than wide indicate an affinity to the genus Kinosternon. The presence of a marked scar for the insertion of the cervico-plastral ligament on the visceral surface of the epiplastron indicates a close relationship to Kinosternon leucostomum and Kinosternon scorpioides. More shell and cranial material must be found in order to define precisely if the Kinosternon of Pubenza corresponds to some extant species, or if it is a new extinct species.

We studied these aspects of social monogamy in kit foxes (Vulpes macrotis) at 1 urban and 2 nonurban sites. Behavior was similar across sites despite differences in ecological conditions. Pair formation occurred throughout the year, often within a month after the loss of a mate. Pair-mates associated throughout the year. Some pairs remained associated for more than 1 breeding season. Death of a pair-mate was the most common reason for the dissolution of a pair (14 of 16 cases). Two pairs dissolved while both partners were still living: 1 due to abandonment by a male of his pair-mate and territory and 1 due to displacement of a male by another male. These characteristics of social monogamy in kit foxes may be related to year-round territoriality, and may optimize individual fitness by enhancing survival and ultimately reproductive success.

A new display, head tossing, has been observed on repeated occasions by five different males (all Ardeotis kori struthiunculus) in the Smithsonian National Zoological Park, Dallas Zoo, and San Diego Wild Animal Park. This display has not been reported for A. k. kori or in any other Ardeotis species. Trained behavior watchers recorded detailed observations of a male bustard's booming behavior and frequency in 2004 and 2005; over the 2 years they collected 407 hrs of booming data. Head tossing occurred when the male rapidly threw his head backward onto his back. The head tossing display further exposed the white neck feathers and the motion of head tossing was extremely visible. Head tossing was followed by a cessation of booming or was a transition between additional booming sessions. Head tossing primarily occurred at the end of a six-boom calling bout (90% of the time) and was observed infrequently (less than 2% of all booming bouts). Head tossing appears to occur predominantly during the early phases of the breeding cycle and may function as a territorial marker directed at other males, and potentially provides information about the rank of the displaying male.

In this study we test the time required until metamorphic competence in the veliger larvae of four species of Phestilla nudibranch. Larvae of Phestilla melanobrachia are planktotrophic and had the highest percentage of metamorphosis in response to the prey coral Tubastraea aurea. Twelve days after hatching these veligers had approximately 30% metamorphosis in response to Tubastraea aurea polyps and to waterborne compounds released from T. aurea. Larvae of the facultative lecithotroph Phestilla sibogae had the highest rates of metamorphosis in response to Porites cylindrica after five days. However, P. sibogae also had approximately 50% metamorphosis in response to the non-prey coral Turbinaria reniformis. Phestilla minor had significantly more metamorphosis in response to Porites annae than to filtered seawater. Phestilla minor was the only species to have spontaneous metamorphosis in response to filtered seawater; 27% metamorphosis was observed after four days. The lecithotroph Phestilla sp. 2 had 80% metamorphosis in response to its host coral Goniopora fruticosa and to waterborne cues from G. fruticosa five days after hatching. This species also had approximately 40% metamorphosis in response to non-prey corals Porites cylindrica and Turbinaria reniformis. These different larval development times make Phestilla spp. an ideal group to study the ecological and evolutionary consequences of different life history strategies in marine invertebrates.

Here, I present a large-scale, statistical survey of evolutionary mode in fossil lineages. Over 250 sequences of evolving traits were fit by using maximum likelihood to three evolutionary models: directional change, random walk, and stasis. Evolution in these traits was rarely directional; in only 5% of fossil sequences was directional evolution the most strongly supported of the three modes of change. The remaining 95% of sequences were divided nearly equally between random walks and stasis. Variables related to body size were significantly less likely than shape traits to experience stasis. This finding is in accord with previous suggestions that size may be more evolutionarily labile than shape and is consistent with some but not all of the mechanisms proposed to explain evolutionary stasis. In general, similar evolutionary patterns are observed across other variables, such as clade membership and temporal resolution, but there is some evidence that directional change in planktonic organisms is more frequent than in benthic organisms. The rarity with which directional evolution was observed in this study corroborates a key claim of punctuated equilibria and suggests that truly directional evolution is infrequent or, perhaps more importantly, of short enough duration so as to rarely register in paleontological sampling.

Paleoproductivity never reached a eutrophic threshold value above which we would predict opposite trends of high paleoproductivity and low diversity, consistent with stressful conditions. Instead, results are similar to those from other studies of oligotrophic settings that show a positive and statistically significant correlation between paleoproductivity and diversity. The correlations between current intensity and watermass oxygenation with diversity are negative and statistically significant. These results are also borne out by Principal Component Analysis (PCA). Intervals of increased relative abundance of Epistominella exigua, a proxy for seasonality of phytodetrital input to the seafloor, coincide with increased diversity, suggesting that pulsed paleoproductivity enhanced the diversity signal in the Caribbean. Diversity and paleoproductivity peaked in the Caribbean at 7.9 Ma, and declined thereafter due to the cut off of the nutrient-rich Pacific deep waters (<1000 m) into the Caribbean. From 7.6 to 4.2 Ma, both diversity and paleoproductivity increased. With the complete closure of the Caribbean-Pacific seaway at 4.2 Ma, both diversity and paleoproductivity gradually decreased from a high at 4.2 Ma to moderate values until the end of the study interval at 2.5 Ma. Major intervals of significant shifts in Caribbean diversity and paleoproductivity were also confirmed with SHEBI analysis that displays a diverging trend between the Pacific and Caribbean sites since 7.9 Ma, with the Caribbean displaying decreasing values. In summary, in the Caribbean, decreased paleoproductivity due to the gradual constriction and the final closure of the Central American Seaway (CAS) led to decreased deep-sea benthic foraminiferal diversity and that both benthic foraminiferal diversity and paleoproductivity maintained a positive relationship.

The new species, Neomegalodon cornutus and Quemocuomegalodon circularis, are described. The type species of Quemocuomegalodon, Q. orientus, is revised. Quemocuomegalodon orientus Yao, Sha, and Zhang (2003) is now known from abundant, well-preserved specimens that show great variation in shape, size, thickness of shell, and dentition, and the species Q. longitatus, Yao, Sha, and Zhang (2003) is now placed in synonymy with Q. orientus. There are significant morphologic differences between the external appearance of shelled specimens and the internal molds of species of Quemocuomegalodon. This suggests the need for the re-evaluation of many megalodontid species from elsewhere that are known only from internal molds.

AN - 50255923; 2008-069830 AB - The equatorial Medusae Fossae Formation (MFF) is enigmatic and perhaps among the youngest geologic deposits on Mars. They are thought to be composed of volcanic ash, eolian sediments, or an ice-rich material analogous to polar layered deposits. The Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) instrument aboard the Mars Express Spacecraft has detected nadir echoes offset in time-delay from the surface return in orbits over MFF material. These echoes are interpreted to be from the subsurface interface between the MFF material and the underlying terrain. The delay time between the MFF surface and subsurface echoes is consistent with massive deposits emplaced on generally planar lowlands materials with a real dielectric constant of approximately 2.9+ or -0.4. The real dielectric constant and the estimated dielectric losses are consistent with a substantial component of water ice. However, an anomalously low-density, ice-poor material cannot be ruled out. If ice-rich, the MFF must have a higher percentage of dust and sand than polar layered deposits. The volume of water in an ice-rich MFF deposit would be comparable to that of the south polar layered deposits.

The ~60,000-year interval (~1.845-1.785Ma) above Tuff IB records evidence for lake and fluvial sequences, volcanic eruptions, eolian and pedogenic processes, and the development of a fluvial plain in the western margin of the basin. Significant temporal variation in the carbonate @d18O values records variation of local precipitation and supports the shifts in climatic conditions interpreted from the lithologic record. During this period, carbonate @d13C values varied between depositional facies indicating that the paleolandscape supported a local biomass of about 40-60% C"4 plants within a mosaic of grassy woodlands and wooded grasslands. The lithologic and stable isotope record in this small lake basin indicates the area was much wetter, with more woody C"3 plants, during this interval than is the semi-arid area today. The record also reflects the variation in climatic conditions (wet/dry) documented by other global climate proxies for this time.

Much of the soil phosphorus occurs in a series of organic compounds that differ in their availability to organisms, but changes in the relative abundance of these compounds during pedogenesis remain unknown. We used alkaline extraction and solution phosphorus-31 nuclear magnetic resonance spectroscopy to assess the chemical nature of soil organic phosphorus along a 120,000-year post-glacial chronosequence at Franz Josef, New Zealand. Inositol phosphates, DNA, phospholipids, and phosphonates accumulated rapidly during the first 500 years of soil development characterized by nitrogen limitation of biological productivity, but then declined slowly to low concentrations in older soils characterized by intense phosphorus limitation. However, the relative contribution of the various compounds to the total organic phosphorus varied along the sequence in dramatic and surprising ways. The proportion of inositol hexakisphosphate, conventionally considered to be relatively recalcitrant in the environment, declined markedly in older soils, apparently due to a corresponding decline in amorphous metal oxides, which weather to crystalline forms during pedogenesis. In contrast, the proportion of DNA, considered relatively bioavailable in soil, increased continually throughout the sequence, due apparently to incorporation within organic structures that provide protection from biological attack. The changes in soil organic phosphorus coincided with marked shifts in plant and microbial communities, suggesting that differences in the forms and bioavailability of soil organic phosphorus have ecological significance.

This region is isolated by Pacific dry forests north and south and isolated from Caribbean wet forests by mountains. We studied three sympatric lowland frog species in the Craugastor fitzingeri species group that prefer wet forest but differ in their response to dry habitats. In dry forest, C. fitzingeri can survive along streams while C. crassidigitus and C. talamancae are entirely absent. We collected samples from across the ranges of all three species, and obtained mitochondrial DNA sequence data from the COI and cytochrome b genes. We observed significant phylogeographical structure in C. crassidigitus and C. talamancae, but much less in C. fitzingeri, demonstrating that mountain barriers and dry forest habitat have reduced mitochondrial gene flow in the strictly wet-forest species. Additionally, we discovered that the Golfo Dulce and Central Panama populations of C. crassidigitus appear to have diverged in the Pliocene or earlier, suggesting that the dry forest separating these populations is old. Our phylogenetic analysis of 12 of approximately 16 species of the C. fitzingeri species group suggests that the three lowland species are each other's closest relatives. Because of this shared phylogenetic history, we attribute the striking differences in phylogeographical structure to the different ecologies of the frogs. In summary, we find that what appear to be minor differences in the natural history of these three closely related species may profoundly impact the potential for dispersal, range size, and cladogenesis.

To learn what could be explained without invoking Darwinian adaptive divergence, Hubbell devised a similar neutral theory for forest ecology, assuming each tree is equally likely to reproduce whatever its species. In both theories, some predictions worked; neither theory proved universally true. Simple assumptions allow neutral theorists to treat many subjects still immune to more realistic theory. Ecologists exploit far fewer of these possibilities than population geneticists, focussing instead on species abundance distributions, where their predictions work best, but most closely match non-neutral predictions. Neutral theory cannot explain adaptive divergence or ecosystem function, which ecologists must understand. By addressing new topics and predicting changes in time, however, ecological neutral theory can provide probing null hypotheses and stimulate more realistic theory.

The two populations are described as separate subspecies or species on the basis of size and plumage differences. We assessed genetic variation in blood samples from 15 individuals in the modern Nihoa population using approximately 3000 base pairs (bp) of mitochondrial DNA (mtDNA) sequence and 14 microsatellite loci. We also obtained up to 1028 bp of mtDNA sequence from the fragmented DNA of museum specimens of three birds collected on Nihoa in 1923 and five birds collected on Laysan in 1902 and 1911 (ancient samples). Genetic variation in both marker types was extremely low in the modern Nihoa population (nucleotide diversity [ pi ] = 0.00005 for mtDNA sequences; observed heterozygosity was 7.2% for the microsatellite loci). In contrast, we found three mtDNA haplotypes among the five Laysan individuals ( pi = 0.0023), indicating substantially greater genetic variation. The Nihoa and Laysan taxa differed by 1.7% uncorrected mtDNA sequence divergence, a magnitude that would support designation at the subspecies, and perhaps species, level relative to other closely related Acrocephalus species pairs. However, in light of strong ecological similarity between the two taxa, and a need to have additional populations to prevent extinction from stochastic effects and catastrophes, we believe these genetic differences should not deter a potential translocation of individuals from Nihoa to Laysan.

Molecular genetic approaches have been found to be powerful tools for investigating the ecological and evolutionary aspects of biological invasions because the genetic structure and level of genetic variation of an invasive species are changed following its invasion. The present article reviews the use of molecular markers in addressing various aspects of invasive species. The application of these techniques has shown that many invasive species are actually "cryptic" species - species whose uniqueness is only recognizable at the genetic level. An estimation of the actual number of invasive species is essential when evaluating its ecological and economic impacts. Molecular genetic approaches have also enabled the source populations of invasive species to be identified. Reconstructions of invasion histories are crucial to preventing future invasions and conserving the native biodiversity, while comparisons of genetic variations between the native and introduced populations provide valuable opportunities to elucidate the mechanisms of rapid adaptation demonstrated by many invasive species.

In such a case, do resistant individuals recolonize from a central remnant population, or do they spread from small, perhaps overlooked, populations of resistant individuals? Introduced avian malaria (Plasmodium relictum) has devastated low-elevation populations of native birds in Hawaii, but at least one species (Hawaii amakihi, Hemignathus virens) that was greatly reduced at elevations below about 1000 m tolerates malaria and has initiated a remarkable and rapid recovery. We assessed mitochondrial and nuclear DNA markers from amakihi and two other Hawaiian honeycreepers, apapane (Himatione sanguinea) and iiwi (Vestiaria coccinea), at nine primary study sites from 2001 to 2003 to determine the source of re-establishing birds. In addition, we obtained sequences from tissue from amakihi museum study skins (1898 and 1948-49) to assess temporal changes in allele distributions. We found that amakihi in lowland areas are, and have historically been, differentiated from birds at high elevations and had unique alleles retained through time; that is, their genetic signature was not a subset of the genetic variation at higher elevations. We suggest that high disease pressure rapidly selected for resistance to malaria at low elevation, leaving small pockets of resistant birds, and this resistance spread outward from the scattered remnant populations. Low-elevation amakihi are currently isolated from higher elevations (> 1000 m) where disease emergence and transmission rates appear to vary seasonally and annually. In contrast to results from amakihi, no genetic differentiation between elevations was found in apapane and iiwi, indicating that slight variation in genetic or life-history attributes can determine disease resistance and population recovery. Determining the conditions that allow for the development of resistance to disease is essential to understanding how species evolve resistance across a landscape of varying disease pressures.

On frosty mornings, horses browse inside bubbles of steam and leave a sweet leathery odor behind them, invisible clouds above jumbled hoofprints. Spring through fall, the horses live unaided by humans, wading in the ponds and grazing on bushes, tree branches, algae and grass. In winter, horses paw the snow to find grass or rotting apples, and rangers of the mounted Horse Guard sometimes provide hay and salt. Fighting with bared teeth is common among the stallions. Meanwhile, the origins of the herd spur antagonism among zoologists, with some calling the animal near-tarpans. Tarpan boasts a multitude of other species, from one-celled protozoan to boar, elk, lynx, wolf, moose and bison.

In Varanasi, India's most sacred city, the coliform bacterial count is at least 3,000 times higher than the standard established as safe by the United Nations World Health Organizations. Ganga Action Plan (GAP) has shut down some of the most egregious industrial polluters and allocates about $ 100 million for constructing wastewater treatment plants in 25 cities and towns along the river. The pathogens, channeled from treatment plants into irrigation channels, seep back into the groundwater, where they enter the drinking-waters supply and breed such diseases as dysentery, as well as skin infections.

AN - 14830298; 10725571 AB - Various aspects related to use of biofuels are discussed. Biofuels produce carbon dioxide, which is the major cause of global warming. Corn, soybeans, palm oil, grasses, trees and other biofuel feedstocks can recapture, through photosynthesis, the massive quantities of carbon dioxide they release. Ethanol producers in America receive tax credits of 51 cents a gallon, on top of billions of dollars in direct corn subsidies. It is predicted that reallocation of farmland due to biofuel incentives can combine with bad weather to cause food shortages around the world. If cellulosic ethanol becomes practical, biofuel will provide at best only part of the solution to the problems of global warming and energy supply.

The jaguar is the Western hemisphere's largest feline and the third largest cat in the world. A number of U.S. conservation groups step in to try to save the Sonoran jaguars. It is postulated that the jaguars in the U.S. wander up from the northernmost known breeding population in Mexico, which lies 140 miles south of the border in Sonora. Jaguars in the U.S. wander up from the northernmost known breeding population in Mexico, which lies 140 miles south of the border in Sonora. Jaguars are solitary animal and as young adults must strike out to find their own territory.

Fossil data provide the most tangible evidence for the origin of early animal lineages, although additional evidence from molecular phylogenetics, molecular clock studies, and development has contributed to our current understanding. We review several lines of evidence to explore the nature and timing of early metazoan evolution and discuss how these data, when considered together, provide a more cohesive picture of the origin of animal diversity. We discuss how trace fossils and biomarkers provide compelling evidence for the origins of Bilateria and siliceous sponges. Using a molecular phylogenetic framework for metazoans, we discuss how fossils can be used to date the origin of clades. We use these fossil dates to perform a relaxed molecular clock analysis for estimating dates of nodes when no fossils are available. We also discuss current data from developmental biology that suggest that early metazoans possessed a sophisticated molecular toolkit for building complex body plans. We conclude that the best evidence for the origin of major metazoan lineages lies in the careful interpretation of the fossil record and that these data, when considered with phylogenetic and developmental evidence, support the notion that the Cambrian radiation is a real phenomenon that marks a critically important time in the history of life.

Further, cnidarian jellyfish comprise an important component of modern marine planktonic ecosystems. Here we report on exceptionally preserved cnidarian jellyfish fossils from the Middle Cambrian ( approximately 505 million years old) Marjum Formation of Utah. These are the first described Cambrian jellyfish fossils to display exquisite preservation of soft part anatomy including detailed features of structures interpreted as trailing tentacles and subumbrellar and exumbrellar surfaces. If the interpretation of these preserved characters is correct, their presence is diagnostic of modern jellyfish taxa. These new discoveries may provide insight into the scope of cnidarian diversity shortly after the Cambrian radiation, and would reinforce the notion that important taxonomic components of the modern planktonic realm were in place by the Cambrian period.

Claims vary from persistent overuse to traditional practices of sustaining the resource base. Arguments for either side routinely draw from contemporary situations, relying on relatively short time periods. But, if the notion ''sustainable'' is to be consequential, the period under consideration must be meaningful - claims that trends over a few years or even decades are representative of long-term phenomena are questionable, for they depend on numerous untested, if not untestable, assumptions. Research in anthropology, biology, biological conservation, ecology, policy, restoration ecology, social development, and wildlife management is routinely constrained to relatively short time periods, and such results are of limited value for evaluating sustainable use. Archaeozoology provides unique tools for investigating trends in human-resource relations over periods of centuries and millennia; it is one of the few disciplines explicitly dedicated to the study of material evidence over significant time periods that bears directly on the question of sustainable use. Hence, objective, scientific evaluation of sustainable use must contemplate archaeozoological evidence. Yet, archaeozoology often does not provide definitive answers: it is wrought with fundamental problems in sampling, data gathering, analysis, and interpretation (e.g., varying screen sizes; meta-sampling procedures; comparisons across diverse spatial, temporal, and environmental continua; etc.). Typically data must be evaluated through inference, rather than through direct observations and experiments. Moreover, environmental variation (e.g., climate change, sea level change, tectonic movement, etc.), as well as changes in societies, confounds the interpretation of long-term human-environmental trends. But, those challenges are not unique to archaeozoology, for biological and ecological phenomena are no less subject to multiple sources of environmental and social variation. The difference is that archaeologists are patently cognizant of these sources of variability, and they openly debate them when interpreting data, while in other disciplines these sources of change are routinely ignored. Nonetheless, despite the unique relevance of their work, few archaeozoologists have ventured outside their discipline to engage natural scientists and policy makers in issues of biological conservation and wildlife biology, and particularly the root questions of sustainable use. In addition to considering data and hypotheses regarding long-term prehistoric human-wildlife interactions, it is essential to view this information within broader perspectives, linked to other disciplines as well as to contemporary social and policy issues. Because sustainable use is mandated in international instruments and national policies, the notion has relevance in arenas far beyond academia, where archaeozoologists must be integrated into interdisciplinary teams.

These skipper butterflies are unquestionably distinct species, as evidenced by genitalic and facies differences and by ecologic segregation, i.e., one species of each pair in dry forest, the other in adjacent rain forest in Area de Conservaci6n Guanacaste in northwestern Costa Rica. This national park is the source of the specimens used in this study, all of which were reared. Larval foodplants are of no or problematic value in distinguishing these species. Large samples of individuals whose barcodes are acceptably long reveal slight interspecific differentiation (involving just one to three nucleotides) in all three pairs of skippers. Clearly, the chronic practice of various taxonomists of setting arbitrary levels of differentiation for delimiting species is unrealistic.

Both minerals occur in cavities in steeply dipping alpine-type fissure veins that crosscut highly deformed migmatitic schists and quartz-biotite gneiss of the Inner Piedmont Belt. Preliminary fluid inclusion data from quartz crystals in the cavities constrains the crystallization temperature and pressures of the fissure veins mineralization to <250 degrees C and near 1 kbar. Sulfide mineralization occurs in two separate vein assemblages: (1) beryl-bearing fissure veins that carry accessory pyrite (FeS (sub 2) ), pyrrhotite (Fe (sub 1-x) S), sphalerite (ZnS), chalcopyrite (CuFeS (sub 2) ), and trace amounts of galena (PbS) and (2) spodumene-bearing veins that host pyrite, pyrrhotite, molybdenite (MoS (sub 2) ), and trace gersdorffite (NiAsS). The sulfides generally form as part of the last stage of mineralization in the cavities. The crystal morphology and chemical composition of pyrite reflect slightly different fluid chemistries of the two vein types. Pyrite cubes are characteristic of the spodumene-bearing veins whereas octahedra are typical of the beryl-bearing veins. Pyrites of the beryl-bearing veins contain higher As and Ni values compared to those from spodumene veins. Pyrite from the spodumene assemblage is enriched in Cu and Mn relative to pyrite from the beryl assemblage. The physical and chemical properties of pyrite and associated sulfides may serve as an important exploration tool for identifying emerald- or hiddenite-bearing veins in the Hiddenite area.

All three of these variables are scale-dependent, and in real-life situations such data are always "noisy"; that is, incorrect dates, misidentifications, and approximate locations are common features of such data sets. Procedures for identifying a geological or biological signal through such noise fall into the framework of exploratory data analysis. stratigraph is a software toolbox, now available in pre-release versions, to analyze and display such data. Specifically, functions are currently available to read pollen or other micropalaeontologial data from and write them to standard interchange formats, and to plot pollen diagrams. Current software tools for this kind of analysis include expensive commercial packages like Rockware, StratBugs, and CANOCO, but menu-driven compiled software does not provide the generality or flexibility needed to tune analyses to particular data sets. stratigraph is intended to show the advantages of interactive data analysis via open-source scripting in a high-level programming language. While menu-driven software may eventually be needed by some end-users, the programers writing such software are seldom scientists or familiar with the detailed questions that their programs will be used to answer. Instead, community-supported, open-source software is an ideal locale in which to develop new methodologies or implement established methods in stratigraphic paleontology.

Here, we investigate the ecological and evolutionary processes underlying this taxonomic diversification. We previously reported that the increase in alpha diversity from the mid-Paleozoic to the late Cenozoic correlates with an increase in the number of distinct ecological modes of life within single assemblages, where modes of life are defined on an animal's motility level, feeding mechanism, and position relative to the substratum. When examined in more detail, the increase in the number of ecological lifestyles within assemblages largely reflects the rise of infaunal and motile lifestyles among suspension feeders: the diversity and evenness of suspension-feeding modes of life within assemblages changed little from the Paleozoic to the Cenozoic, but more of these modes of life are layered into the multiple tiers of the average Cenozoic assemblage. The increase in alpha diversity also results from an expansion in the abundance and diversity of predators, many of whom divide niche space by specializing on prey taxa. We believe that increased energetics in marine ecosystems through time allowed the rise of modes of life with high metabolic rates, such as burrowers and predators. Studies of the modern Adriatic Sea (McKinney 2007) support this theory: epifaunal communities occur in areas of low primary productivity, whereas infauna are common where productivity is high. In the Cenozoic, diversity is highest in assemblages in which infauna and epifauna overlap (i.e., where the number of modes of life is highest), a situation that was difficult to achieve in the Paleozoic because infaunal animals were less abundant. Thus, expanded occupation of ecospace, likely driven by increased energetics, played a major role in Phanerozoic diversity history.

Recent attempts to resolve the affinities of this leaf morphotype have failed because of too little amber material for an interpretable signal in spectral analyses, or the absence of diagnostic leaf cuticle. Moreover, the new patagonian records of "Z." tertiaria belong to an evolutionarily iterative and undiagnostic homeomorph series throughout the early and middle Paleogene that feature lanceolate, entire-margined, broad leaves with parallel veins, absence of a keeled or discernible midvein, attributable to unrelated gymnospermous lineages. Fortunately, "Z." tertiaria has a distinctive suite of specialized insect herbivore damage types (DTs). These include slot feeding (DT8) between primary veins; and a distinctive, frass-laden, elongate blotch mine (DT88). Piercing-and-sucking damage occurs as interveinal, ellipsoidal punctures with prominent reaction rims (DT48), or ellipsoidal scale-insect impressions (DT86) on leaf surfaces with thick rims surrounding an internal region of undulose texture. Two distinctive gall types are present: ellipsoidal blister galls (DT115) with thickened, carbonized margins encircling an epidermal covering; and, vascularly deep-seated and protruding columnar galls (DT116) with amber or sediment infill of the central chamber. These six and other associations constitute a component community mostly of host-specialized endophytic feeders on "Z." tertiaria, some of which occur on the same host at multiple localities. Most revealing regarding the affinities of "Z." tertiaria is the leaf mine, which resembles blotch structures made by the plutellid Chrysorthenclites (Lepidoptera: Plutellidae) on extant Podocarpus from New Zealand and Tasmania. Also, the columnar gall is very similar to certain pitch moths (Lepidoptera: Tortricidae) on some Oceanean Podocarpaceae. Affinities of the other DTs remain enigmatic. Although modern Agathis has similar mines produced by Parectopa (Lepidoptera: Gracillariidae), the bulk of evidence (mine and gall) suggests that "Z." tertiaria is more likely to be a podocarp.

For features with wavelengths less than about 100 meters, TARs on Mars may be the product of either ripple-related or dune-related emplacement processes. The Mars Exploration Rovers have documented the presence of granule ripples (sand-cored features coated with essentially a mono-layer of granules, particles typically 1 to 2 mm in diameter) at both of their landing sites. However, orbital images, including the fantastic new products currently being obtained by the High Resolution Imaging Science Experiment (HiRISE), are not able to resolve the size of particles that comprise aeolian bedforms on Mars. We have collected detailed topographic profiles across aeolian bedforms ranging from typical sand ripples (wavelength of about 10 cm) to granule ripples (generally wavelengths of 1 to 5 m) to transverse sand dunes, both active and stabilized (wavelengths generally greater than 50 m), which comprises a rich data set to which measurements of TARs can be compared. This report presents some of our first results of photoclinometrically derived topographic profiles across TARs that are present in the first full-resolution HiRISE image released to the public, covering a portion of the floor of Ius Chasma within the immense Valles Marineris canyon system. The TAR profiles are generally steeper in slope and more symmetric (relative to the crest) than the terrestrial bedform profiles. TAR shapes are more divergent from the shapes of both sand ripples and sand dunes than they are from the shape of granule ripples. We are convinced that TAR profiles from HiRISE images can provide a valuable tool for assessing the probable formation mechanism of aeolian bedforms in the 10 to 100 meter wavelength range from regions all across Mars.

Four main geologic features are present in the mapping area: 1) the main shield, 2) the rift aprons, 3) plains lava flows, and 4) a fan-shaped debris apron. Along with the current version of the geologic map, we will present a focused analysis of the geomorphology and formation of chasmata associated with the rift zones. The rift aprons extend from the lower northeast and southwest flanks of the main shield. At the apex of the rift aprons are a dense concentration of intertwined chasms and chains of pit craters that together make up the rift zones. Morphologically, the chasms have theater-shaped heads and narrow downstream. The orientations of the chasms trend with the slope of the main shield. No levees or flow margins are apparent giving the individual chasms a morphologic appearance similar to lunar sinuous rilles. The chasms are typically 1-3 km wide, with some coalesced areas up to 8-km-wide, and are 100's of meters deep, based on MOLA gridded data (128 pixels/degree). High-resolution images from MOC (2.9-6.1 m/pixel) and High Resolution Imaging Science Experiment (HiRISE) (0.25 m/pixel) reveal layers of bedrock in the upper quarter to upper half of the chasm walls, with the lower sections of the walls covered by debris and dust. HiRISE image PSP_001642_1895 shows at least ten layers of bedrock cropping out in a staircase-like fashion in the upper quarter of a chasm wall on the southwest flank of Ascraeus Mons. We interpret the bedrock layers observed in this HiRISE image to be lava flows that were emplaced during construction of the main shield, which are now exposed as a result of the chasm formation. Formation of the chasmata is thought to be by various processes including volcanic, tectonic, fluvial, and glacial or a combination thereof. We agree with a volcanic origin for the chasmata, formed by high volume, long duration eruptions and the release of volatiles along a NE-SW trending rift zone. Chasms were modified later by other surface processes. Intruding magma surfaced along the lower flank of Ascraeus Mons feeding the flow field that comprises the rift apron. Understanding the origin of the chasmata will provide better insight into the eruption dynamics required to form the rift aprons.

It has a 20-MHz center frequency and 10-MHz bandwidth, providing a vertical resolution of 15 m (free space) and a horizontal resolution of several km. The radar has been particularly successful in sounding the polar deposits of Mars. SHARAD is complemented by the lower frequency, narrower bandwidth, capability of the MARSIS sounding radar aboard the Mars Express orbiter. MARSIS has a coarser vertical resolution of 150 m, but in many places can map the interface at the base of the polar deposits whereas SHARAD cannot. The northern deposits can be divided into two lobes, in part separated by Chasma Boreale, centered roughly on 0 degrees and 180 degrees longitudes. In the 0 degrees lobe, SHARAD sounds to the base of the deposits and finds essentially no flexural/membrane downwarping due to the depositional load at the cap. The uncertainty in this measurement is about 50 m, and conservatively we state that there has been no more than 100 m of flexural/membrane response to the load. Thin elastic spherical shell loading models show that to get less than 100 m of deflection, the elastic thickness must be at least 300 km. By Earth analogy, the base of the elastic lithosphere is in the temperature range 500-600 degrees C. This yields a lithospheric temperature gradient of approximately 2 K/km, a significantly sub-Chondritic value and likely an unrealistic result. The alternative interpretation is that the lithosphere has not yet reached elastic equilibrium with the load. The controlling factor is the viscosity of the mantle, and a bound on the age of the load provides a bound on mantle viscosity. For example, for a more reasonable elastic thickness of 100 km, a load age of 100 Kyr corresponds to a mantle viscosity of about 10 (super 23) Pa-s. The flexural deflection limit, using MARSIS, under the South Polar deposits is about 300 m due largely to the rugged nature of the heavily cratered substrate. But the age of the load is greater than 10 (super 7) years, implying a mantle viscosity greater than roughly 10 (super 24) Pa-s. In all, relatively high viscosities and relatively low temperatures are implied for the Martian mantle.

Living forcipulataceans occur primarily in cold-water settings-polar and deep-sea environments at depths ranging from the intertidal (0-2 m) to the abyss (>1000 m). In spite of a highly diverse range of body plans, forcipulataceans are morphologically distinctive, displaying several immediately recognizable diagnostic features, including 3 piece crossed pedicellariae, four rows of tube feet, fused proximal adambulacral ossicles (called an adoral carina) and a reticulate skeleton. Although the group is easy to identify, classification among certain forcipulatacean taxa, especially within the Asteriidae has been historically problematic. 12 and 16S sequence data was sampled and sequenced from 50 taxa representing all major forcipulatacean groups, including the Asteriidae, Pedicellasteridae, Labidiasteridae, Pycnopodiidae, Heliasteridae, Zoroasteridae, and the Brisingida were analyzed using Bayesian and parsimony analyses resulting in largely similar tree topologies. The tree topology is strongly tied with regional diversification. A derived lineage composed of individual Holarctic, Antarctic, and tropical equatorial clades is supported as a sister group to more basal members which occur primarily in the Southern Hemisphere and in deep-sea regions. Zoroasterid and brisingid lineages are supported as monophyletic although exact relationships between these and other basal forcipulataceans is ambiguous. The Labidiasteridae, which has long been perceived as a non-natural grouping, is shown to be polyphyletic and should be synonymized. The Pedicellasteridae, which has been perceived as intermediate between forcipulataceans and other asteroids is not supported as monophyletic with taxa supported in the derived and basal lineages. Asteriid taxa in the basal Southern Hemisphere/deep-sea lineage are morphologically most similar to Jurassic asteriids described by Blake (1990) and Hess (1972) whereas fossils and geological events, such as isolation of the Southern Ocean suggest the derived lineage as occurring more recently. Brooding of juveniles is observed only from the Antarctic and Holarctic lineages on distantly related clades.

With respect to identifying gradual phyletic change, randomly generated sequences may exhibit characteristics of a "trend"; apparent patterns, therefore, must be interpreted with caution. Furthermore, even when the claim of a gradual trend can be statistically justified, interpretation of the underlying mechanisms may be challenging. Given that we can observe populations changing rapidly over 10's or 100's of years, it is now more difficult to explain instances of geologically gradual (as opposed to punctuated) change. Here we describe morphologic change in two bivalve lineages from the late Miocene Lake Pannon. We evaluate change according to the model-based methods of Hunt (2006). Both lineages exhibit size increases and shape changes over an interval of approximately 3.5 m.y. Size increase in both lineages and shape change in one lineage (using eigenshape and PCA) are best fit by a model of directional evolution (general random walk); most remaining shape variables are best described as unbiased random walks. Parallel trajectories of increasing log shell height over time suggest comparable directionality in the two lineages. We tested this possibility by fitting a set of models to the two sequences. The models differ in two ways: whether dynamics are the same or different in the two lineages, and whether evolution is directional (general random walk) or not (unbiased random walk). Of the four possibilities, the data overwhelming support the model in which evolutionary dynamics are directional and shared across the two lineages, suggesting that the size increases may be a shared response to the same cause. Although the European Neogene has been well studied in terms of paleoenvironment, we can identify no environmental parameter that exhibits consistent change across the interval of gradual morphologic change. It may be that in Lake Pannon the long-term persistence of generally ameliorating conditions (plentiful resources and habitat space, few predators or competitors) resulted in anagenetic change (including size increase) in some lineages and numerous branching events in other lineages.

Gingerich has shown that rates measured in this manner show a strong inverse relationship with the interval over which they are observed. Many causes have been invoked to account for this temporal scaling of rates, including: evolutionary reversals of direction, plotting a ratio versus its denominator, and limits on the minimum detectable and maximum feasible rates. Here I discuss an alternative rate metric that is based on the single generating parameter of the unbiased random walk model. This metric, called Delta when proposed by Lynch, has very broadly useful properties, such as being estimable from phylogenetic as well as ancestor--descendant relationships. Perhaps most importantly, it can be shown that Delta is independent of temporal scaling when phenotype truly evolves as a random walk. I have used this metric to measure evolutionary rates in a large set of stratophenetic series, and in a much smaller number of phylogenetic data sets. Despite the fact that Delta avoids or mitigates the putative causes of time-scale dependence, an inverse relationship between evolutionary rate (measured as Delta ) and elapsed time persists in these data sets. These results suggest that rates of evolution are, in a meaningful sense, faster when observed over shorter temporal scales; the inverse temporal scaling is not simply a statistical artifact. The negative temporal scaling of Delta indicates that morphological evolution generally deviates from an unbiased random walk in showing less morphological change over longer intervals than would be predicted from shorter-term excursions, implicating stabilizing selection (or other conservative processes) in limiting long-term divergence. While it can be straightforward to devise a rate metric that is uncorrelated with elapsed time under specific modes of evolution, it is probably not possible to measure rates in a way that works equally well under different evolutionary modes (e.g., random walks, stasis, directional change). Nevertheless, because of its statistical and practical advantages over traditionally defined rates, Delta is recommended for general use as the best of the currently available options.

Few studies have examined variability in carbon isotopic composition of bulk organic matter along a single stratigraphic horizon that captures different depositional settings, floral communities or microbial processing during pedogenesis. A wide diversity of biotic and physical processes affect organic matter source and preservation in lithologies ranging from lignites to oxidized paleosols, which could affect the stratigraphic pattern of carbon isotope composition and ultimately result in miscorrelation. We document carbon isotope variability along five laterally extensive carbonaceous beds in the Paleocene Fort Union and Eocene Willwood formations of the Bighorn Basin, Wyoming (USA). Isotope values vary 0.2 to 0.9ppm VPDB (95% confidence intervals) within single beds across lateral distances of 100s to 1000s of m. Weight percent of organic carbon varies from 0.6 to 54.8%. Observed isotopic differences likely reflect systematic offsets caused by differences in floral inputs, preferential loss of certain organic compounds, or microbial processing during pedogenesis. In spite of observed variations in the carbon isotopic composition of organic matter within each bed, there is a pronounced long-term change in mean carbon isotope values from 60 Ma (-25.0ppm) to 52.6 Ma (27.6ppm), which approximately tracks isotopic records from marine carbonate. Comparisons of terrestrial organic isotopic records with estimated carbon isotope values of atmospheric carbon dioxide inferred from marine foraminifera allows us to compare expected and measured values. Our findings suggest modest caution in using carbon isotopes for comparisons across multiple terrestrial sections due to subpermil-scale intrabed isotopic variability. Nonetheless, our data from an array of terrestrial facies yield composite carbon isotope values that track the predicted exogenous carbon pool.

Times of rapid global change are catalysts for evolution. Here we present three examples of accelerated rates evolutionary turnover (speciation plus extinction) during the Mid-Cretaceous likely associated with times of changing upper water column stratification, ocean chemistry, and productivity during Oceanic Anoxic Events (OAEs). Planktonic foraminifers diversified greatly during the late Aptian ( approximately 119-113 Ma) as witnessed by increased numbers of species, test size, and morphologic variability, including the first appearance of a peripheral keel. Multispecies stable isotope evidence indicates that species were stratified in the upper water column (mixed layer and thermocline) similar to modern taxa. This radiation was followed by a diversity collapse across the Aptian-Albian boundary ( approximately 112 Ma) associated with changes in global carbonate chemistry during OAE 1b. This is the largest turnover (up to 92%) prior to the Cretaceous/Paleogene boundary. Planktonic foraminiferal simple diversity, test size, calcification, and morphologic variability again increased rapidly during the late Albian ( approximately 105-99 Ma). This radiation parallels trends in rising sea level and global warming, and is associated with increased stratification of the water column and upper water column based on multispecies oxygen isotope evidence. The development of regional OAEs (1c, 1d) or OAE-like times of enhanced organic matter production during the late Albian, suggest that productivity variability may have also been a contributing factor for high rates of turnover at this time. OAE 2 during the latest Cenomanian-earliest Turonian ( approximately 94-93 Ma) was one of the most widespread and best developed of the OAEs. The planktonic foraminifers display a significant turnover that mostly affected deep-dwelling taxa, including the extinction of the long-ranging Rotalipora and the radiation of Dicarinella, among others. Multispecies oxygen isotope data suggest that deep waters warmed to at least 18 degrees C and upper water column stratification collapsed during OAE 2.

It is generally agreed that wrinkle ridges are the result of compressional stresses and crustal shortening and are the surface expression of folding and thrust faulting. One of the most debated aspects of wrinkle ridge formation is the depth of faulting. It has been proposed that wrinkle ridge thrust faults are either deeply rooted (thick-skinned deformation) or shallow (thin-skinned deformation). Models of wrinkle ridge formation are based on their morphology, the regional topography of ridged plains, and ridge spacing. One of the most striking features of wrinkle ridges on plains units is their regular spacing. This regular or periodic spacing is strongly suggestive of dominant or critical wavelength deformation. Ridge spacing on scales to tens of kilometers can be accounted for with buckling and localization instability models where the lithosphere is free to deform. Larger scales of folding and faulting on the order of hundreds of kilometers can also be accounted for. Conversely, a buckling instability where the lithosphere is assumed to be rigid and decoupled from the deforming ridged plains material can also account for the ridge spacing. The apparent "stair step" topography of Martian ridged plains have been attributed to a stacked group of thrust faults with depth-scales of tens of kilometers, possibly cutting the entire elastic and seismogenic lithosphere. Recent modeling has attempted to define the geometry and number of thrust faults needed to account for the major morphologic elements of Martian wrinkle ridges. These models require a deeply rooted primary thrust fault and one or two secondary backthrusts to account for the typical broad low relief arch and the superimposed ridge. An alternative model accounts for the morphology of wrinkles ridges with a single listric thrust fault that flattens into a mechanically weak horizon. Thus, the question of the maximum depth of wrinkle ridge thrust faults remains unanswered.

Nueces Bay receives freshwater from the Nueces River, which enters at the south shore. From 1998 to 2007 foraminifers were sampled on a mid-bay, north-south transect at five different stations. The populations were sampled during periods of low inflow (mean monthly discharge of .47-2564 ft (super 3) /s, 1998-2002), high inflow (mean monthly discharge of 19.69-16,170 ft (super 3) /s, 2002-2003), and relatively moderate inflow (mean monthly discharge of 7.12-196.83 ft (super 3) /s, 2006-2007). During the low inflow period, the Central Power and Lighting Plant (CPL) was in operation at the south shore, pumping heated, more saline coolant water into the bay. Salinities were nearly constant, ranging from 23-27 ppt at the stations. Results from the 1998-2002 sampling showed statistical differences in total populations and community structure between the north and south shores, as well as a high incidence of shell dissolution. In the 2003 samples, taken after the CPL closed and the area received abundant precipitation, salinities varied from 12 ppt at the south shore to 21 ppt at the north shore. Foraminiferal abundance was from 6-98 times greater, there were no differences in total populations or community structure, and there was a low percentage of shell dissolution. To see how populations respond during more moderate inflow, a final set of samples was taken in 2007. Salinity at the southernmost station was 21 ppt, and at the northernmost it was 30 ppt. Data thus far show that total densities are intermediate between those recorded during low and high discharge conditions, and that there is again an increased occurrence of shell dissolution. This project establishes the receptivity of foraminifers to short-term fluctuations in freshwater inflow, and highlights their value for monitoring discharge into Texas estuaries. The ability of foraminifers to respond to changing environmental circumstances may be a characteristic that imparts species resilience through time.

Benthic foraminifera provide a perspective to address this shortcoming, thus enabling a better understanding of Maastrichtian deep ocean dynamics. At a deep-sea site on Blake Nose (western subtropical North Atlantic), benthic foraminiferal data indicate low productivity and well-oxygenated environment between 72-69.4 Ma marked by high % of Eouvigerina spp., Nuttallides spp. and Gavelinella spp., low magnetic susceptibility (MS), high benthic delta (super 13) C and lightness (L*) values. High productivity and low oxygen conditions are noted between 69.4-68.1 Ma with low % of Eouvigerina spp., Nuttallides spp. and Gavelinella spp., high % of Praebulimina spp. and Bulimina kugleri, high MS, low benthic delta (super 13) C and L* values. Previous studies have noted that Eouvigerina spp., Nuttallides spp. and Gavelinella spp. prefer well-oxygenated low organic flux environments whereas species of Praebulimina and Bulimina are adapted to modern high productivity low oxygen conditions. Negative and significant correlations between Eouvigerina spp. and Praebulimina spp. and Bulimina kugleri also indicate differing habitat preferences between the former and the latter two species. Eouvigerina spp. correlates significantly and negatively with MS and positively with L*, corroborating the preference of this species for low productivity conditions. In summary, at Site 1052E, during the interval of the inoceramid decline and eventual extinction at approximately 68.5 Ma, high productivity and low oxygen conditions prevailed. This contrasts with the previous hypothesis that suggested increased oxygenation as the probable cause for the final demise of this important bivalve group. However, it is also plausible that regional dynamics (the availability of nutrients, changes in the intensity of upwelling, etc.) might have played a far greater and varying role than previously thought leading to the extinction of inoceramids.

B, 1951. Foraminifera Distribution, Part I. Geological Society of America Memoir 46, 1-88.] and Parker [Parker, F. L., 1954. Distribution of the foraminifera in the Northeastern Gulf of Mexico. Bulletin of the Museum of Comparative Zoology 111, 453-588, 13 plates.] form the benchmark foraminiferal data sets for the northwestern and northeastern Gulf of Mexico, respectively. These pioneer researchers occupied stations from shelf to abyssal depths. SHE analysis, a method examining the distribution of cumulative sample values of species richness (S), the information function (H) and evenness (E) with increasing number of individuals (N), was used to establish 18 foraminiferal communities and evaluate their community structure. Regression analyses, as well as plots of lnS, H and lnE versus lnN (Biodiversitygrams, BDGs), indicate that the majority of the communities exhibit a log series pattern. Theoretical log series values of S, H and E are similar to the regression estimates from observed values in the northeastern Gulf. In the northwestern Gulf, however, observed values of species richness are lower and evenness higher than those expected for a log series, indicating a dramatic difference in community structure between east and west. Since the sampling time of Phleger, subsequent workers have found higher values of species richness and lower values of evenness in the northwestern Gulf. Either biodiversity values have changed since Phleger's 1947 (1951) sampling suggesting a fundamental change in the environmental regime of the northwestern Gulf of Mexico or, as has been suggested, Phleger's data are incorrect due to some sampling methodology. A comprehensive study with suitable experimental design including downcore samples will be required to resolve this dichotomy.

Reconciling these records requires either that marine carbonates fail to record the full magnitude of the CIE or that the CIE in plants has been amplified relative to the marine. Amplification of the CIE has been proposed to result from an increase in available moisture that allowed terrestrial plants to increase (super 13) C-discrimination during the PETM. Leaf physiognomy, paleopedology and hydrogen isotope ratios of leaf-wax lipids from the Bighorn Basin, however, all suggest that rather than a simple increase in available moisture, climate alternated between wet and dry during the PETM. Here we consider two other explanations and test them quantitatively with the carbon isotopic record of plant lipids. The "marine modification" hypothesis is that the marine carbonate record was modified by chemical changes at the PETM and that plant lipids record the true magnitude of the CIE. Using atmospheric CO (sub 2) delta (super 13) C values estimated from the lipid record, and equilibrium fractionation between CO (sub 2) and carbonate, we estimate the expected CIE for planktonic foraminifera to be 6 ppm. Instead, the largest excursion observed is about 4 ppm. No mechanism for altering marine carbonate by 2 ppm has been identified and we thus reject this explanation. The "plant community change" hypothesis is that major changes in floral composition during the PETM amplified the CIE observed in n-alkanes by 1-2 ppm relative to marine carbonate. This effect could have been caused by a rapid transition from a mixed angiosperm/conifer flora to a purely angiosperm flora. The plant community change hypothesis is consistent with both the magnitude and pattern of CIE amplification among the different n-alkanes, and with data from fossil plants. This hypothesis predicts that the magnitude and pattern of amplification of CIEs among different n-alkanes will vary regionally and systematically depending on the extent of the replacement of conifers by angiosperms during the PETM.

Together they provide valuable along-arc information about magma generation processes. The volcanoes have erupted low-K basalts originating from both wet and dry parental basaltic magmas (low-Zr basalts and high-Zr basalts, respectively). Based on models involving fluid-immobile incompatible element ratios (La/Sm), the parental basalts appear to result from different degrees of partial melting of the same source mantle ( approximately 20% and approximately 10% for wet and dry basalt magmas, respectively). Assuming that the wet basalts contain greater abundances of slab-derived components than their dry counterparts, geochemical comparison of these two basalt types permits the identification of the specific elements involved in fluid transport from the subducting slab. Using an extensive set of new geochemical data from Torishima, where the top of the downgoing slab is about 100 km deep, we find that Cs, Pb, and Sr are variably enriched in the low-Zr basalts, which cannot be accounted for by fractional crystallization or by differences in the degree of mantle melting. These elements are interpreted to be selectively concentrated in slab-derived metasomatic fluids. Variations in K, high field strength element and rare earth element concentrations are readily explained by variations in the degree of melting between the low- and high-Zr basalts; these elements are not contained in the slab-derived fluids. Rb and Ba exhibit variable behaviour in the low-Zr basalts, ranging from immobile, similar to K, to mildly enriched in some low-Zr basalts. We suggest that the K-rich mica, phengite, plays an important role in determining the composition of fluids released from the downgoing slab. In arc-front settings, where slab depth is < or =100 km, phengite is stable, and the fluids released from the slab contain little K. In back-arc settings, however, where the slab is at 100-140 km depth, phengite is unstable, and K-rich fluids are released. We conclude that cross-arc variations in the K content of arc basalts are probably related to differing compositions of released fluids or melts rather than the widely held view that such variations are controlled by the degree of partial melting.

Trace metal chemistry of airborne and surface outdoor dust was measured and described within Fallon (case town) as well as in other nearby similar towns and outlying desert areas (comparison towns). Multiple lines of evidence, including airborne dust filtered directly from air, deposited dust collected from ground surfaces, and lichens collected from native bedrock, indicate high levels of airborne tungsten and cobalt within Fallon relative to comparison towns and pristine desert. Morphological and chemical analyses of airborne tungsten particles of Fallon indicate that they are anthropogenic in origin, i.e., pure tungsten or tungsten carbide with traces of cobalt and other metals. Dendrochemical analysis of tree rings within Fallon indicates that environmental tungsten has increased in availability since the mid-1990s, at or about the time of onset of the cluster of childhood union. Although these findings do not directly link exposure to airborne tungsten and cobalt to childhood leukemia, they do suggest new lines of biomedical research to evaluate if such linkages exist. More generally, geochemistry of multiple lines of evidence can identify distinctive environmental qualities of towns, and those distinctions can then be investigated further in directed public health research.

Integrating geochronology and stratigraphic studies (the EARTHTIME initiative) AN - 50642881; 2008-107680 AB - Precise and accurate knowledge of geological time is central to understanding Earth history. While geologists depend on published timescales, many are not aware of the details of the age data which underpin its calibration. Most timescales are necessarily based on interpolation between geochronological tie points of variable quality that are often determined by averaging dates obtained using different techniques. Recent advances in geochronology and correlation methods allow us to develop a calibrated geological timescale with significantly improved accuracy and precision. Ultimately this allows us to address the rates of geological, biological, and climate change in geologic time. All who use the geological timescales should understand the details of how they are constructed, considering the power and limitations of geochronological and correlation techniques. The EARTHTIME initiative (http://earth-time.org) has been developed as a community-based effort to focus attention on the calibration of at least the last 800 million years of Earth history. This requires using a unified, multi-chronometer (radio-isotopic and cyclostratigraphic) approach integrated with paleo-biological and paleo-climatic proxy datasets. This in turn will permit Earth scientists to realize and address a new series of questions that rely on knowledge of precise rates of biological, geological, and climatic change, allowing for example, assessment of links between marine and terrestrial realms, or synchroneity/ordering of events for intervals of interest. New developments in geochronological techniques have enabled dating of ash beds intercalated with fossil-bearing sedimentary rocks at unprecedented levels of precision (0.1-0.05%). This high level of precision has in turn identified issues of accuracy such as interlaboratory and/or inter-decay scheme bias. A major goal of EARTHTIME is to address and resolve these issues. Progress must still be made on the intercalibration of high-precision U-Pb datas with timescales based upon 40K decay scheme and/or astronomical cyclicity to achieve the goal of seamless calibration of geological time. Ultimately, the level of involvement of the geologic community, geochronologists and paleontologists in particular, will determine the degree to which the goals of EARTHTIME are realized.

Twenty-one bulk-collected and sample-unbiased floras, each representing from 175 to 2289 specimens, were ordinated by pollen zonation into K (Maastrichtian, 3 floras), P1 (Puercan, 5 floras), P2 (Puercan/Torrejonian, 1 flora), and P3 (Torrejonian, 11 floras). We analyzed damage diversity (using rarefaction) and damage frequency for these floras, indicating a highly elevated level of K herbivory, a modest level for P1 and perhaps P2, and a uniform decrease during P3. However, for the P1 sites, this gross analysis may disproportionately inflate generalized damage occurring multiply on the same leaf since these sites have few specialized DTs. Newly discovered associations are almost entirely confined to a few K floras, and exhibit the targeting of particular tissues, host monospecificity, and typical confinement to single sites. The most prominent pattern is five DTs on a particular Laramie palm species found at sites 2174, 2362 and 3213, whose damage is controlled by venation. These palm associations include two DTs of ellipsoidal scale insect impression scars; elongate, black oviposition scars; tubular, frass filled mines constructed probably by beetles; and small, ellipsoidal punctures likely made by a heteropteran piercer-and-sucker. In addition, three mine DTs include a distinctive, robust, full-depth leaf mine on Platanites marginata (locality 2302) revealing an incidence rate of 27.8 % (N = 209 leaves); a unique mine whose terminal stages have removed midrib vascular tissue from "Ficus" planicostata (probable Lauraceae); and a thick, tubular mine occurring on the pinnule margin of the fern Allantodiopsis erosa. Denver Basin DT diversity attests to a high intensity of insect herbivory on varied vascular plants during the latest K and a dramatic decrease by P3 times. This pattern is generally similar to that of the Williston Basin, 750 km to the north, with the possible exception of somewhat higher levels during P1 + P2.

Romer's Gap is immediately preceded in the Late Devonian by several genera of aquatic, limbed vertebrates with features that later became exaptations for a terrestrial lifestyle, referred to as terrestrialization Phase 1B. A considerably earlier Early and Middle Devonian diversification of terrestrial arthropods (hexapods, arachnids and myriapods) consisting of 22 major lineages conventionally considered as orders, is termed Phase 1A. Romer's Gap is succeeded during the Middle Mississippian through Lower Permian by a diverse expansion of major arthropod and limbed vertebrate lineages (Phase 2), representing a threefold increase of 66 additional ordinal-level lineages. Explanation of Romer's Gap is linked to ambient atmospheric oxygen levels. A recent recalculation of Devonian ambient oxygen levels based on the (super 13) C composition of brachiopod calcite is congruent with the (smoothed) trend established by the earlier GEOCARBSULF model in 2006. The only significant departure is the raising of O (sub 2) level by 1 to 3 % during the Middle (Eifelian) to Late (Famennian) Devonian, corresponding to a low of 16 % (mid Frasnian) but throughout remaining significantly depressed compared to the present atmospheric level of 21 %. This O (sub 2) minimum is associated with arrested cladogenesis of arthropod lineages, indicated by a prolonged and zero ordinal origination rate. This minimum continues into the Visean, through Romer's Gap, but is followed by a dramatic monotonic elevation to 29 % at the mid Early Permian (Phase 2). This latter increase parallels physiological advances in arthropod and vertebrate respiratory efficiency, new modes of insect herbivory, arthropod gigantism, and increased complexity in terrestrial food webs. The four independent replicates of macroscopic animal clades (hexapods, arachnids, myriapods and stegocephalians) indicate that a minimal threshold of around 20 % atmospheric oxygen is necessary for diversification of land-dwelling life.

Past work inferred that it was emplaced via tubes and inflated sheets, although only indirect evidence of tubes was found. Here we discuss field work on the Carrizozo vent region, comprising a low shield approximately 7 by 5 km in diameter, rising up to 60 m above the pre-flow terrain. From the western flow margin, Differential Global Positioning System (DGPS) data show three topographic plateaus increasing to 2, 8, and 10 m, and possibly a fourth at 12 m, above the adjacent terrain across 1.2 km towards the vent. The discontinuous plateaus include lava collapse and rise pits. 30 m/pix Shuttle Radar Topography Mission (SRTM) and DGPS data show that plateaus are typified by <1 degree slopes, except across pit walls where slopes are steeper. SRTM derived slopes increase from 2 to 9 degrees across the next 1.3 km, rising 50 m above the plateau terrain to the summit. The near vent region is typified by more numerous collapse and inflation pits resulting in a less uniform plateau surface. The vent (Little Black Peak) is capped by a approximately 30 m tall cinder pile and small ( approximately 5 m) summit depression. Although Little Black Peak is the prominent summit feature, the vent area appears to comprise a set of three coalesced cinder piles and a perched lava pond. East of the main vent is a collapsed lava tube, exposing a network of three branching tubes that descend into the eastern flow field at different topographic levels. Lava flow textures and structures suggest that the Carrizozo low shield was built through a combination of several tube-fed sheet inflation events, breakouts resulting in small surface lava flows, and several mildly explosive episodes at the vent. The eruption also fed a much more extensive, likely tube-fed lava flow beyond the extent of the primary low shield for 10s of kilometers. Therefore, the bulk of the flow field is located beyond the extent of the Carrizozo low shield. Similar small-vents are seen in clusters on Mars and elsewhere on the Earth. The distribution of lava deposits at Carrizozo suggest that care should be taken when estimating low shield volume or surface area based on remote sensing data alone, particularly if the vent is located within a field of vents where embayment of extensive lava flow fields might have occurred.

AN - 50550011; 2009-002925 AB - Extremely friable, finely fenestrate biofabric reforms episodically in sandy Saharan biomantles immediately after rare rainfall events. (Biofabric is soil fabric produced by biodynamic processes.) The lifeform types and numbers involved in producing Saharan biofabric are unknown and cryptic, but a gram of typical humid mid-latitude biofabric is estimated to contain such enormous numbers and diversities of lifeforms as: bacteria (10 (super 8-9) ), actinomycetes (10 (super 5-8) ); fungi (10 (super 5-6) ); micro-algae (10 (super 3-6) ); protozoa (10 (super 3-5) ); nematodes (10 (super 1-2) ); other invertebrates (10 (super 3-5) ). Such lifeform numbers are greater per gram than there are people on Earth. Saharan soil lifeforms are narrowly adapted to long periods of drought, often covering many decades, during which no sign of surface life meets the eye. When rain falls, and the soil wets, long dormant organisms spring into life, as observed in January, 1978, weeks after a rare rainfall on 16-17 December, 1977. Our observations were made below the Kiseiba Escarpment in the western Kiseiba-Dungul Depression, south-central Egypt. In 1996 multiple backhoe pits were dug on this surface. The soils in each pit were destratified to bedrock (1-2 m depth), except for a thin (1-8 cm) stratified, episodically mobile surficial sand layer. The soils thus constitute whole soil biomantles, entirely bioturbated and destratified. In January 1998, two years after the pits were dug, the soils were reexamined. Backhoe spoils were initially heaped into conical piles, whereupon the extreme fragility and friability of the soil, plus the mechanical disturbance of excavation, caused most of the sandy soil to be destructured into loose single grains. However, a few fist-sized chunks of the biofabric fortuitously remained intact on most every spoil-pile, each exposed to 2 years of dry, gentle, micro-sculpting by wind. The result was a rare view into extremely friable and delicately fenestrate biofabric composed of miniature biopores, micro-inosculate biochannels, sediment-ingested micropellets, and organism-rearranged grains, expressed three dimensionally as 100 per cent "fossil" biofabric. Insofar as biofabric is a signature aspect of all Earth's soils, might minimalist versions, produced perhaps by minimalist lifeforms, be biomarkers in the soils of planets that bear, or once bore, life?

Consequently, they are expected to have a wider distribution among microhabitats than late successional, "specialized" plants, although they may not display a high abundance in all habitats. Hypotheses about ecological strategy of taxa can be tested using abundance distribution data along relevant environmental resource gradients, but such data are generally not available for fossil plants. The Big Cedar Ridge ashfall flora from the Late Cretaceous Meeteetse Formation, Wyoming, is an exception. Plants are preserved in situ at the base of a tuff along a 4 km long outcrop. The flora is dominated by ferns, palms, and to a lesser degree conifers, but also preserves many rare dicotyledonous angiosperms. It has been hypothesized that the dicotyledons were early-successional generalists that were only abundant in physically disturbed sites with low levels of soil carbon. We tested this hypothesis by examining the abundance distribution of individual Big Cedar Ridge plant taxa along a gradient of soil organic content. The data suggest that many plants, whether widely or narrowly distributed, appear to have a wide tolerance for variation in soil carbon content. However, there are differences in the relative abundance distribution along this gradient among represented plant groups. Many ferns, conifers, cycads, and monocotyledons show a relatively even abundance distribution along their tolerance interval or a higher abundance at higher levels of soil carbon (>40%). Whereas some dicotyledons are similarly evenly distributed along their tolerance interval, others are very rare in soils with >10% soil carbon. This pattern indicates that there may have been variation in fundamental niche breadth in terms of soil organic content among different plant taxa (including among different dicotyledons), that the distribution of plants across microhabitats was influenced by factors other than soil organic carbon, or a combination of both.

Its 20-MHz center frequency and 10-MHz bandwidth complements the lower frequency, relatively narrower bandwidth capability of the MARSIS sounding radar aboard the Mars Express Orbiter. SHARAD has been in operation since November, 2006, and has already acquired a large volume of data. The radar is particularly good at mapping the internal, fine-scale layering in the deposits at the North and South Poles of Mars. At the North Pole, SHARAD paints a three-dimensional picture of the stratigraphy mapped (by visible imaging) in canyon exposures on the periphery of the cap. Differences in elevation across the cap are seen to be caused by a relatively constant thickness ice-rich layered unit resting on a more coarsely layered basal deposit that is of variable thickness and likely contains a sand component. In both the North and South Polar regions, SHARAD has mapped angular unconformities, possible faulting, and possible folding. Also detected are layered ice deposits on the periphery of the caps. SHARAD has also mapped subsurface reflectors at mid- and low-latitudes on Mars. In Amazonis Planitia, SHARAD has mapped an interface at 40-90 m depth along the margin of a high 12.6-cm backscatter area as mapped by Earth-based radar and interpreted to be a lava flow. The best explanation for subsurface reflections across Amazonis is that they arise from the interface between lava flows and underlying sediments. There is little support for a near-surface ice-rich sediment layer in Amazonis Planitia. Similarly, in the southern Elysium region of Mars, a vast area ( approximately 500,000 km (super 2) ) contains deposits that are transparent to SHARAD radar waves and have a depth of approximately 70 meters as observed by SHARAD. Other observations, from visible images and spectrometers, indicate that these deposits are of volcanic origin. Further to the west, in the area considered by some workers as the "Frozen Sea" ( approximately 5 degrees N-150 degrees E) SHARAD does not detect any evidence of ice. Elsewhere in the northern lowlands of Mars, subsurface reflectors have been detected and the analyses of these results are ongoing.

The young appearance of the northern plains lead to the interpretation that the northern lowlands crust could also be relatively young. This view changed when subdued quasi-circular depressions (QCDs) in the northern lowlands were revealed in Mars Orbiter Laser Altimeter (MOLA) data. Interpreted to be buried impact craters, the QCDs suggest that the crater age of the northern lowlands crust is ancient. The initial operations of the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) instrument on Mars Express in June-July, 2005 were over the northern lowlands. Data obtained over this period revealed evidence of 11 buried impact basins ranging in diameter from about 130 km to 470 km. Four of these basins coincide with previously mapped QCDs. The buried basins detected by MARSIS were used to estimate an independent areal crater density N(200), a measure of the cumulative number of basins with diameters >200 km per 10 (super 6) km (super 2) , for the lowland crust. The area of the northern lowlands surveyed in the data obtained in 2005 by MARSIS is estimated to be about 14% of the lowlands. This corresponds to an N(200) crater density for the lowland crust of approximately 1.9. The N(200) crater density and the cumulative frequency plot of the MARSIS basins suggest an early Noachian age for the northern lowland crust. MARSIS data collected over northern lowlands from about April 2006 to April 2007 are now being analyzed for evidence of other buried basins. Preliminary results suggest the presence of many previously unidentified buried basins. This work, in combination with ongoing efforts to refine the number of QCDs, should greatly improve our understanding of the age of the northern lowlands crust and ultimately the origin of the crustal dichotomy.

Modern ecological conditions in YNP are the nearest to "natural" that the ecosystem has experienced in the past century. During the previous 150 years the large mammal fauna of YNP, including wolves (Canis lupus), elk (Cervus elaphus), and bison (Bison bison), have undergone multiple episodes of exploitation, extinction, and protection. We used carbon and nitrogen stable isotope values measured in faunal bone collagen to study species interactions among YNP wolves and ungulates from two ecologically important time periods; the first captures historic YNP (1902-1916) during the final years that wolves were present, prior to reintroduction, and the second captures modern YNP (1997-2004) in the first years after wolves returned to the ecosystem. Elk and bison population sizes were also different between these time periods, with many fewer elk and bison in the early 1900's than today. We investigated the feeding preferences of historic and modern wolves, and found that both populations were elk-specialists with relatively low levels of intra-populational isotopic variance. Historic elk and bison had similar diets that were more variable than elk and bison diets today. We also analyzed serial samples taken from modern elk hooves, and generated chronologies to quantify elk seasonal migration and foraging behaviors. We found that historic grassland fauna (wolf, elk, bison) have higher nitrogen isotope values than the modern grassland fauna. We propose that this difference reflects the effects of grazer abundances on YNP grassland nutrient processes, such as nitrogen cycling. Smaller grazer population sizes in the early 1900's, due to intense exploitation during the previous century, had ecosystem-wide repercussions that were recorded in the nitrogen isotope values of historic consumers, including wolves.

While the origin of the PETM remains contested, globally distributed isotope records indicate rapid warming and introduction of isotopically-depleted carbon into the ocean/atmosphere system. While multiple hypotheses to resolve the PETM carbon cycle perturbation have been suggested, limited geological evidence exists for any model proposed. Modeled data and field studies demonstrate detrital apatite and zircon (U-Th)/He (He) and fission-track (FT) age anomalies (i.e., FT ages < He ages) can be used as indicators of fires in the modern. In the first paleo-application of it kind, we address the proposed hypothesis that the PETM was caused by burning of terrestrial organic matter by analyzing detrital grains from terrestrial sediments within the Powder River and Bighorn Basins. Limited zircon recovered from Powder River's Wyodak-Anderson coals are clearly volcanic in origin, roughly consistent with Absaroka volcanism and likely deposited as atmospheric fallout. Bighorn apatite grains recovered from a series of fluvial and paleosol sediments are more intriguing, in that FT ages are nearly all approximately 55 Ma while He ages record more scatter and generally yield ages 55 Ma or younger. Currently, explanations for this wide distribution in He ages are equivocal. Nonetheless, the 55 Ma apatite FT ages are robust, and from a regional perspective, unlikely to have come from the Bighorn or Owl Creek Mountains. This limits us to three possible explanations for the preservation of a strong 55 Ma signal in these detrital grains; either 1) from exhumation of the Beartooth Mountains, 2) reworking of or fallout from Absaroka volcanism or, 3) resetting by wildfire at or near time of deposition. Paleo-drainage patterns indicate the Beartooth Mountains are an unlikely source for these apatites. At this point, either Absaroka volcanism or resetting by fires remains equally plausible explanations. However, if the grains source from the Absarokas we predict that both the zircon and micas ages would be 55 Ma, whereas, if fire reset the apatite FT ages, the zircon and micas ages would be older than 55 Ma.

Although Prototaxites was nutritionally heterotrophic and a probable saprobe on thick accumulations of plant litter, little is known of its ecological relationships with other organisms. However, borings consistent with an arthropod origin are known and exhibit characteristic tunnel geometry, evidence of host fungal response to tunneling, and distinctive internal contents. Two specimens of bored Prototaxites are known: one from the Early Devonian (Emsian) of Gaspe, Quebec, and other from the Late Devonian (Famennian) of Kettle Point, Ontario. The network of borings in the Kettle Point specimen exhibits several features involving arthropod penetration of live fungal tissue, perhaps analogous to extant beetle borings in hardened bracket fungi. An extensive, rarefied tissue zone, reminiscent of necroses in plant tissues, surrounds the borings. This contrasts to an inner, thin but variably thickened, opaque region of hyphal mat lining the tunnel, analogous to plant callus and indicating host response. Small coprolites, 100-200 mu m in diameter, bear degraded tubular (hyphal) structures that occasionally protrude above their smooth surfaces, suggestive of digestive processing. Each coprolite is enveloped by a narrow evacuated zone, suggesting in situ shrinkage. Reconstruction of the tunneling network is ongoing, but preliminary observations reveal a 3-D, unoriented network interrupted occasionally by more expansive galleries. The arthropod culprit remains unidentified. Devonian possibilities include oribatid mites, albeit the disparity between small coprolite size and a much larger tunnel diameter is incongruous. These networks also are inconsistent with known myriapod life-habits, and any similarity to holometabolous larval or adult insect borings is countered by a 55 m.y. gap before the earliest occurrences of such derived insects. Identity aside, the borer of chitin-bearing fungal tissue may have switched to lignified woody plant tissue during the Late Devonian.

Reconciling these records requires either that marine carbonates fail to record the full magnitude of the CIE or that the CIE in plants has been amplified. Amplification of the CIE has been proposed to result from an increase in available moisture that allowed terrestrial plants to increase 13C-discrimination during the PETM. Leaf physiognomy, paleopedology and hydrogen isotope ratios of leaf-wax lipids from the Bighorn Basin, however, all suggest that rather than a simple increase in available moisture, climate alternated between wet and dry during the PETM. We consider two other explanations and test them quantitatively with the carbon isotopic record of plant lipids. The "marine modification" hypothesis is that the marine carbonate record was modified by chemical changes at the PETM and that plant lipids record the true magnitude of the CIE. Using atmospheric CO2 delta (super 13) C values estimated from the lipid record, and equilibrium fractionation between CO2 and carbonate, we estimate the expected CIE for planktonic foraminifera to be 6ppm. Instead, the largest excursion observed is about 4ppm. No mechanism for altering marine carbonate by 2ppm has been identified and we thus reject this explanation. The "plant community change" hypothesis is that the observed major changes in floral composition during the PETM amplified the CIE recorded in n-alkanes by 1-2ppm relative to the ocean-atmosphere CIE. This effect could have been caused by a rapid transition from a mixed angiosperm/conifer flora to a purely angiosperm flora. The plant community change hypothesis is consistent with both the observed magnitude and pattern of CIE amplification among the different n-alkanes, with longer chain-lengths demonstrating greater amplification. This hypothesis predicts that the magnitude and pattern of amplification of CIEs among different n-alkanes will vary regionally and systematically depending on the extent of the replacement of conifers by angiosperms during the PETM. Carbon isotope analyses of modern conifers and angiosperms will further refine quantitative predictions of the isotopic effects of plant community change.

This sudden global warming, called the Paleocene-Eocene Thermal Maximum (PETM), lasted approximately 150 ky and appears to have been caused by the release of approximately 4,500 Gt of carbon to the atmosphere-ocean system. Fossil floras from the upper Fort Union and lower Willwood Formations in the Bighorn Basin of Wyoming provide a continental record of this climatic event and demonstrate its effects on terrestrial vegetation. Leaf margin analysis of the floras shows approximately 5 degrees C of warming during the PETM, consistent with the magnitude of warming estimated from oxygen isotope change in continental vertebrates and planktonic foraminifera. Leaf size analysis of PETM floras suggests that precipitation decreased at the beginning of the event, then fluctuated, consistent with paleosol features in the same area. Comparison of PETM plant fossils with latest Paleocene and early Eocene floras in the same area shows a nearly complete turnover in composition over this brief time. Pre- and post-PETM floras are dominated by deciduous plants in Betulaceae, Platanaceae, Cercidiphyllaceae and Taxodiaceae, among others. PETM floras are characterized by a high abundance and/or diversity of Fabaceae and Anacardiaceae among other families, and conifers are absent. Some PETM plant species present in the Bighorn Basin migrated there from farther south, as shown by Paleocene records from the Gulf Coast and southern Rocky Mountains, and several belong to lineages that are common in seasonally dry subtropical habitats today. The plant fossil record of the PETM demonstrates the large effect of global warming on the composition of mid-latitude vegetation, probably resulting from local extinction and continental-scale change in the geographic ranges of plants over a geologically brief time. The similarity of pre- and post-PETM floras demonstrates that rapid climate change of this magnitude did not result in lineage extinction, implying that cooler-adapted plants survived in higher-latitude or higher-altitude refugia.

Graphic correlation is a methodology to derive precise and relatively accurate biostratigraphic correlations. The analysis is based in calcareous nannofossil, planktonic foraminifera and palynomorph data define chronostratigraphic intervals for the Neogene time. The age of the strata drilled ranged from middle Miocene to Pleistocene. The graphic correlation analysis reveals unconformities that were detected in the wells with early Pliocene strata underlying Pleistocene strata. A hiatus was detected in one well where Pliocene sediments were overlying middle Miocene strata. One of the wells shows the lack of late Miocene fossil markers represented by a hiatus. The composite zonation provides a rapid and consistent subdivision of the Neogene based on recognizable species that can be used to build via graphic correlation a chronostratigraphic framework.

In an age of changing technologies, this means that stewards of collections must be ready to update and retool collections information systems as those technologies and associated research capabilities and questions change. The Smithsonian National Museum of Natural History maintains millions of geological and paleontological specimens and their associated records. Standards and conditions for care of the physical specimens have changed through time but the more significant changes to best practice have occurred in the information management realm. Current information management systems for managing acquisition, loan, disposal and catalog records will be discussed, along with the "lessons learned" associated with developing those systems.

Incomplete records from this interval are due to sea level lowstand and non-deposition. This gap has made the evolutionary record of corals temporally and spatially incomplete. Isla Colon, however, accumulated shallow water sediments during this lowstand period and was subsequently uplifted in the middle Pleistocene. As part of a more regional Caribbean study to investigate evolutionary turnover (Budd 2000), coral fauna from Isla Colon and the stratigraphy of three key formations (Old Bank, La Gruta, unnamed Pleistocene) were sampled and age dated (using Sr isotope ratios, paleomagnetics). Our results indicate that the Old Bank Fm ranges from approximately 5 to 2.5 Ma and the La Gruta Fm ranges between 2.4 to 1.6 Ma. The youngest formation, the unnamed Pleistocene is between 1.2 and 0.8 Ma. A possible hiatus from 1.5 to 1.2 Ma may mark the beginning of uplift. These dates allow us to correlate the reef units to coral deposits Caribbean-wide. The La Gruta carbonate platform records the expansion of the coral Acropora palmata as a major contributor to Caribbean reef systems. This species' role was crucial to reef development during the rapid, high-amplitude sea level changes throughout the Pleistocene. New paleoenvironmental data as well as observations of the island's morphology will help determine the geomorphology and paleoecology of this ancient reef system and allow us to fill the void in coral evolutionary history.

These arid intervals far exceeded in magnitude the aridity of the Last Glacial Maximum in at least parts of tropical/subtropical Africa, and were accompanied by major changes in terrestrial and lacustrine ecosystems. Within the Lake Malawi watershed Zambezian-type woodland was replaced by semi-desert, where vegetation cover and fuel load was insufficient to maintain fire. Lake Malawi itself, presently a freshwater, deep ( approximately 700m) lake housing hundreds of endemic fish and invertebrate species, was transformed into a saline/alkaline lake, a fraction of its current size and approximately 100m deep. These drought episodes and their termination approximately 90ka provide a context for understanding both an hypothesized human population bottleneck suggested by molecular genetic evidence to have occurred in the late-middle or early-late Pleistocene in Africa, and the subsequent rebound of human populations and their expansion out of Africa. Archaeological data show that whereas occupation sites in both North and South Africa are common during the megadrought period, in tropical Africa such sites are rare and restricted to high elevations. Furthermore, archaeological sites become much more common in the immediate aftermath of the worst episodes of megadrought after 90ka. The combined data suggests a most probable period for expansion of anatomically modern humans out of Africa occurring between approximately 90-75ka.

The Olorgesailie Formation, between approximately 1.20 to 0.49 Ma, consists of approximately 80m of diatomite, volcaniclastics, fluvial deposits and paleosols deposited on volcanic basement north of Mt. Olorgesailie, an extinct Pliocene central rift volcano. Lacustrine sediments make up over 70% of the thickness but represent less than 25% of the time spanned by this formation. Two later formations, the Olkesiteti and the Oltepesi, occur both north and west of Mt. Olorgesailie and together span the period from approximately 360 to <64 Ka. These represent multiple cycles of valley incision and filling with approximately 30m of fluvial, volcaniclastic, and lacustrine sediments. All three formations preserve archeological and paleontological sites, with age control provided by interstratified volcaniclastic units. At least 26 different archeological levels occur throughout the sequence. A major episode of valley formation occurred between 490 and 360 Ka and represents a shift in base level likely caused by tectonic activity in the Koora Graben west of Mt. Olorgesailie. Other periods of marked erosion occurred between 210-190 Ka, 150-120 Ka and during the last 10 Ka. Throughout the entire depositional sequence, discrete levels with artifacts and fossils represent relatively short time intervals in which conditions were favorable for accumulation and burial, primarily on soil surfaces, slowly aggrading floodplains and in active channels. Stable isotope analysis of pedogenic carbonate as well as characteristics of the sediments and preserved biota provide paleoenvironmental evidence for these temporary landsurfaces. In contrast, the paleoenvironmental signals preserved within most of the lacustrine and volcaniclastic deposits were recorded during tectonically or climatically controlled intervals of rapid sedimentation. Consequently, the paleoenvironmental record based on the dominant sediments in the three formations is partially de-coupled from the paleoanthropological record. This has important consequences for interpreting environmental controls on the paleoecology of hominins and associated faunas.

Rock and ore specimens have been curated separately from meteorites, minerals and gems since 1881. Data for collection acquisitions and loans yield information about trends in petrology, geochemistry and volcanology, as interpreted by 7 curators through 126 years. Compared to 1955-1956, today's subcollections are larger. More are topical, rather than geographically targeted, and emphasize analyzed materials useful for future research. In 1955-1956, about 500 specimens were acquired per annum; now, annual growth is 1000-3000 specimens. In 1956, the largest new subcollection was 78 rocks collected by William F. Foshag in California and Nevada in 1929. It consists of B ores, sedimentary and volcanic rocks. In 2005, Hatten Yoder's posthumous gift of melilite-bearing rocks totaled 418 specimens, solicited from colleagues to build a collection of Earth's melilite parageneses. Although cataloging of these materials is incomplete, Howard Wilshire's and F. R. Boyd's collections contain over 5000 well-studied mantle xenoliths. Collections are managed electronically, although a written catalog is also maintained. Research loans are our first priority--even unaccessioned specimens are available for study and loans, which are transacted world-wide. Curators do less collecting based on personal interests; instead, they search for scientifically valuable collections (e.g., Earth's mantle, active volcanoes, ore deposits and meteorite impacts). Short-term future goals include a web-based relational database to facilitate queries and sample requests, and cross-reference other databases. By combining growth with increased scientific curation, current curators hope to both build holdings and increase the scientific value of the Smithsonian's rock and ore specimens.

The driving mechanism of these vegetational changes appears to have been climate change associated with changes in ice volume in the south polar region, perhaps ultimately driven by increasing atmospheric CO2. Two basic patterns emerge in the basinal lowlands (where the samples are). 1) Within species pool patterns. Example: Near the Moscovian-Kasimovian boundary, in western and central Pangea, dominant taxa in wetland communities changed significantly from lycopsids to tree ferns during a major ecological reorganization. Tree ferns began rising in abundance in wetlands during the late Moscovian, prior to the regional extirpation, effectively "invading" lycopsid-dominated assemblages, possibly reflecting the beginnings of environmental change. In eastern Pangea (China) wetland assemblages similar to those of the Moscovian persisted into the Late Permian. 2) Between species pool patterns. Example: At the beginning of the Permian in western and central Pangea, seasonally dry assemblages became most common in basinal lowlands as wetlands became increasingly rare and species diversity therein declined. These patterns and associated physical indicators suggest the following. 1) Within species pools, weedy opportunists were significantly advantaged during times of extreme ecological disruption, ultimately giving rise to new ecological dominants. 2) As the areal extent of suitable conditions attenuated, the species richness of wetlands followed suit, with opportunistic and highly specialized taxa retaining dominance. 3) Changes in species-pool-level landscape dominance involved spatial replacement rather than displacement and reflect strong tracking of climatic conditions at the species-pool level.

When the study site is truly remote, such as Mars, examination at the handlens scale is critical both for extracting maximum information and for best utilizing finite analytical capabilities. We conducted fieldwork at Fort Rock tuff ring in central Oregon to test whether rover-inspired field methods would provide handlens-scale images that yield results similar to actual handlens work in the field. Formations of interest were imaged for context at outcrop and unit scale, then specific features were imaged at 10 mu m/pxl. To mimic rover operations, we chose features of interest through macroscale assessment, rather than examination of in situ samples with a handlens and limited the number of images examined to 2-5 per feature. In these images, we were able to identify characteristics of the hydrovolcanic nature of this tuff ring such as coarse-to-fine grained alternating layers and poorly-sorted angular clasts in a clast-supported matrix. Among other results, we found that for one third of the features of interest the few pictures taken were ample for determining the likely nature of the ?feature as a tuff ring, but for two thirds, they were inadequate. At least 2-3 images at 667mu m/pxl and another at 0.5 mm/pxl (imaging areas about 8 cm (super 2) and 65 cm (super 2) respectively) would have been required to eliminate or constrain other possible formation scenarios. For current and future Mars missions, taking "location" images at this intermediate scale would be a useful way to narrow down ideal sites for comprehensive analysis. To assist in interpreting handlens-scale martian images in the future, 10mu m/pxl images taken in this study are being incorporated into an image library, designed to stretch the utility of the limited number of images returned from Mars by providing terrestrial analog comparisons at appropriate resolution.

The sample represents the silicic end-member (67.8 wt % SiO (sub 2) ) of mixed dacite and andesite magmas present in the 1915 Lassen Peak eruptive products. Experiments were performed in Rene-style cold seal hydrothermal pressure vessels run in horizontal split tube furnaces. Run durations were 114-431 hours. Run conditions ranged from 50 MPa to 200 MPa and 700 to 875 degrees C under H (sub 2) O-saturated conditions at the Ni-NiO buffer. The H (sub 2) O-saturated liquidus of the dacite is >875 degrees C and solidus <700 degrees C in the investigated pressure range. All experimental run products contain glass, plagioclase, and Fe-Ti oxides. Other major stable phases include amphibole, pyroxene, and quartz. Biotite is seen in some experiments either displaying breakdown textures or with reaction rims of amphibole or pyroxene + or - plagioclase. Quartz is stable at 50 MPa at all investigated temperatures and is present at or below 800 degrees C at all investigated pressures. At about 850 degrees C, quartz begins reacting with the melt to form reaction rims of pyroxene at 150 MPa and is absent at 200 MPa. At about 875 degrees C, quartz begins to react out at 100 MPa and is absent at and above 150 MPa. Amphibole is stable at 800 degrees C from 50 to 200 MPa, absent below 150 MPa at 850 degrees C and absent below 175 MPa at 875 degrees C. Electron microprobe analyses of glasses produced in experiments and in the natural pumice were collected and these analyses indicate that matrix glasses become progressively silica- and alkali-rich with decreasing P (sub H2O) . Comparisons between experimental and natural phase assemblages and glass compositions suggest that the dacite equilibrated at approximately 50 MPa and 800 to 875 degrees C prior to mixing and erupting with the andesite member. These storage conditions are the basis for a companion study on the kinetics of reaction rim growth on olivine xenocrysts found in the natural dacite and other 1915 eruption products. Mixing experiments are currently underway to reproduce olivine reaction rim textures, and thus, constrain the timing of magma mixing prior to the 1915 eruption of Lassen Peak.

Samples were collected in a nitrogen limited fringe and phosphorus limited dwarf zone, and from an adjacent nitrogen fertilized fringe and a phosphorus fertilized dwarf zone. Inorganic cations and anions, dissolved organic carbon (DOC) and nitrogen (DON) were analysed. Throughfall represented 84% of precipitation volume. Sea salt ions (Cl (super -) , Na (super +) , SO (sub 4) (super 2-) and Mg (super 2+) ) and DOC accounted for the highest proportion of solutes in rainwater, throughfall and stemflow in R. mangle stands. Non-marine sources dominated the flux of DON, DOC, NO (sub 3) (super -) , NH (sub 4) (super +) , and inorganic P (P (sub i) ) in bulk precipitation and throughfall and partially contributed to Ca (super 2+) and K (super +) . Deposition ratios (throughfall deposition:bulk deposition) showed that inorganic NH (sub 4) (super +) , and less so P (sub i) were retained in the canopy of R. mangle from throughfall while all other solutes increased. Canopy leaching contributed in increasing order to net throughfall of Ca (super 2+) , Cl (super -) , SO (sub 4) (super 2-) /K (super +) , Mg (super 2+) and Na (super +) but dry deposition dominated the net throughfall flux during the investigated period. Fertilizer treatment and zone did only slightly affect solute concentrations of hot-water extracts of leaves, of throughfall and stemflow in stands of similar stature. While litterfall and primary production have previously been shown to increase substantially upon nutrient enrichment of mangroves we therefore conclude that fertilization, as a surrogate of anthropogenic eutrophication, may not increase nutrient leaching from mangrove canopies, and thus may only have a minor effect on soluble organic matter cycling and inputs into mangrove food webs.

Vegetation tracked these changes and there is a 1:1 correspondence of species pools with climate proxies: floras dominated by spore-producing plants and primitive seed plants characterize wetter-cooler conditions, with floras dominated by more derived seed plants characterizing drier-warmer conditions. Taxa characteristic of wet habitats, particularly tree ferns and sphenopsids, continued to appear sporadically during periods that physical and chemical indicators suggest were dry-warm, possibly reflecting persistent wet sites on otherwise more xeric landscapes. During the middle Artinskian, parts of the Waggoner Ranch Formation of north-central Texas are characterized by physical and chemical indicators of relatively wetter conditions. Floristically, this interval consists of intercalated "wet", tree-fern-dominated, and "dry", seed-plant dominated floras. Quantitative sampling indicates that there are only minor, but noteworthy, overlaps between the wetter-cooler and drier-warmer species pools. Furthermore, some of the tree-fern-dominated floras contain elements typical of much older floras from the earliest Permian. In several instances, the wet floras occur in channel-form deposits suggesting short, "pluvial" periods. Considering the close association of floral composition and climate, it can be inferred that there were fluctuations in soil moisture and possibly temperature that permitted the short-term spatial expansion of wetland vegetation during the Early Permian, possibly from populations persisting locally in sites marginal to water bodies. These intervals of climatic oscillation further suggest that glacial-interglacial cycles similar to those of the Pennsylvanian also characterized Permian glaciations.

First, scholars have frequently argued that China exerted a disproportionately strong influence on steppe polities, serving as a source of goods and ideas for neighboring pastoralist societies. Although Chinese states did very significantly influence steppe polities, interactions were complex and highly variable. Rather than being dominated by Chinese states, exchanges and interactions were often on a level of parity or were under the control of the steppe polities. It is frequently argued that the fragility of the pastoralist economy required steppe polities to acquire agricultural products, which in turn fostered a dependency on agricultural societies in the south. New evidence, however, suggests that the traditional distinction between pastoralist and agriculturalist economies may be insufficient to characterize the complex sets of interactions. Second, steppe polities are often described as short-lived entities that succeeded each other in rapid succession. This description deemphasizes the economic and cultural continuity that transcended the rise and fall of individual political entities. The third theme concerns the construction and maintenance of order. How, in other words, did rulers legitimate their power and maintain political and organizational control of populations and territories? Most interpretations argue that steppe polities looked to neighboring states for the cultural knowledge that allowed them to create and maintain order. That knowledge, however, came from multiple sources-epecially the internal traditions that linked successive steppe polities.

The maximal rate of sea-level rise that these ecosystems can tolerate depends partly on mineral sediment deposition, but the accumulation of organic matter is equally important for many wetlands. Plant productivity drives organic matter dynamics and is sensitive to global change factors such as elevated atmospheric CO2 and nitrogen eutrophication. It remains unknown how global change will influence organic mechanisms that determine future tidal wetland viability. We manipulated atmospheric CO2 concentration and nitrogen availability (2 x 2 factorial) in a highly organic tidal marsh. Elevated CO2 (ambient + 340 ppm) accelerated soil elevation gain by 3.9 mm yr-1, an effect caused primarily by stimulating belowground plant productivity. Nitrogen additions, despite increasing aboveground productivity, tended to reverse elevation gains, perhaps by reducing root productivity and stimulating soil decomposition. Therefore, increases in the greenhouse gas, CO2, may paradoxically aid some coastal wetlands in counterbalancing rising seas, but nitrogen pollution may negate this effect regionally. These effects on the organic mechanisms of marsh elevation gain may help explain patterns marsh formation and disappearance worldwide.

Seeds were germinated for 1 year at a diel temperature regime (5/1 super(o)C, 14/1 super(o)C, 22/8 super(o)C, or 27/15 super(o)C) or a seasonal regime (seeds moved among the four diel regimes to mimic seasonal temperatures). All species had conditionally dormant seeds at maturity. The optimal temperature for germination of most species was 27/15 super(o)C. The 14 species were grouped by their seed viability, dormancy, and germination with a Seed Regeneration Index (SRI; range 0-1) using the results of this study and a previously published paper on stratification effects on Carex seed dormancy and germination. The eight species that had an SRI value >0.5 (C. brevior, C. comosa, C. cristatella, C. cryptolepis, C. hystericina, C. scoparia, C. stipata, C. vulpinoidea) had high seed viability (>60%) and required little to no stratification to germinate readily over a broad range of temperatures. The six species with an SRI value =50%. These six species will require more attention from restoration practitioners to ensure that there are sufficient viable seeds to meet revegetation goals, that dormancy break is achieved, and that seeds are sown when temperatures are optimal for germination. The different seed germination syndromes that we found for these Carex species likely contribute to variable seed bank formation and emergence patterns, and species coexistence.

It is most similar to D. sapodilla Heppner among described species, both superficially and in the male genitalia. However, the two are easily separated by the long costal fold of the male forewing of D. odorata, which is absent in D. sapodilla. The shapes of the valva and cucullus also distinguish the two. The related D. azteca Walsingham, revised status, which shares a distinct male forewing costal fold with D. odorata, is returned to Dichrorampha. Dichrorampha odorata induces galls in the shoot tips of the invasive weed Chromolaena odorata (L.) R. M. King & H. Robinson (Asteraceae), commonly known as triffid, Jack- in-the-bush, bitter bush, Christmas bush, and Siam weed. The new species appears to have considerable potential as a biological control agent against this weedy shrub in South Africa.

When individuals are not synchronous, however, early breeders depart before the last arrive, so counts underestimate the total breeding population. We present a model describing a colony's census as a function of arrival, breeding tenure, and the correlation between them, and we use it to illustrate how variance in arrival and tenure affect the census. Counts of breeding female northern elephant seals (Mirounga angustirostris) from 1975 to 2007 were used to test the model. Four of the model's parameters-population size, mean and variance of arrival date, and the correlation between arrival date and breeding tenure-could be estimated from census data using a Bayesian approach; prior estimates of two other parameters-mean tenure and its variance-had to be used to avoid overparameterization. The model's predictions fit observed censuses well and produced reliable estimates of population size and arrival behavior, showing that the maximum census was 8%-16% below the total number of breeding females. This method could be used for estimating abundance in any asynchronous aggregation, given independent information on one of the defining distributions: arrival, tenure, or departure.

Invasions have occurred throughout Earth's history, but the scale and tempo has increased strongly in recent time due to global trade. Available data suggest there is a strong latitudinal pattern in recent invasions, with more non-native species documented in temperate marine communities than polar or tropical systems. While this geographic pattern of invasion may reflect some historical biases in search effort and taxonomic knowledge, contemporary surveys also suggest these patterns are robust when controlling for search effort. For example, a standardized survey of sessile invertebrate assemblages in estuaries of western North America found a significant decrease in non-native species richness with increasing latitude (32 to 61 degree N). Several mechanisms may explain the observed invasion pattern across latitudes, operating alone or in combination, such as differences in (a) propagule supply, (b) biotic resistance to invasion, (c) environmental resistance to invasion, and (d) disturbance regime. To date, the relative importance of these mechanisms across geographic regions has not been evaluated, but each may be expected to change over time. Of particular interest and concern are the interactive effects of climate change and human activities on marine invasions, especially at high latitudes. Current climate change models predict not only an increase in sea surface temperatures but also a rapid reduction in sea ice in the Artic. Combined with human responses, climate change is predicted to cause directional shifts in invasion biogeography, including increased invasion opportunity at high northern latitudes.

AN - 20627241; 7972503 AB - Investigating the relationship of biodiversity and ecosystem function in natural forests allows incorporation of established feedbacks between long-lived plants and soil processes. We studied forested stands in northern Arizona that vary in dominant species richness across small areas. We examined the effects of natural variation in dominant tree biodiversity on ecosystem parameters, particularly litter decomposition. We determined not only whether plant species decompose in mixture as predicted by their individual decomposition rates but also: (1) how particular species affect the decomposition rate of each other in mixture; and (2) whether litter decomposes more rapidly at its site of origin; i.e. is there a 'home field advantage' to decomposition? Over a 2-year period, litter mixtures of functionally similar tree species decomposed more rapidly than expected from rates of the individual species alone. Mixtures of conifer species litter decomposed up to 50% faster than expected, with individual conifer members of those mixtures decomposing up to 85% faster than expected. In contrast, more functionally diverse mixtures of litter, which included a deciduous species, did not show synergistic effects during decomposition. We found no significant 'home-field advantage' to decomposition. Our study is the first to demonstrate that litter mixtures from more closely related plant species give rise to the most synergistic effects of biodiversity on litter dynamics, indicating that more taxonomically and functionally diverse plant assemblages do not always drive greater emergent effects on ecosystem function.

Measurements of stable isotope ratios ( delta super(13)C, delta super(18)O, delta super(15)N), elemental concentrations (C, N, P), plant growth, instantaneous leaf gas exchange, and whole-plant water use were used to analyse the mechanisms controlling TE. Plants were grown individually in 19 l pots with non-limiting soil moisture. Soil fertility was altered by mixing soil with varying proportions of rice husks, and applying a slow release fertilizer. A large variation was observed in leaf photosynthetic rate, mean relative growth rate (RGR), and TE in response to experimental treatments; these traits were well correlated with variation in leaf N concentration. Variation in TE showed a strong dependence on the ratio of intercellular to ambient CO sub(2) mole fractions (c sub(i)/c sub(a)); both for instantaneous measurements of c sub(i)/c sub(a) (R super(2)=0.69, P <0.0001, n=30), and integrated estimates based on C isotope discrimination (R super(2)=0.88, P <0.0001, n=30). On the other hand, variations in the leaf-to-air humidity gradient, unproductive water loss, and respiratory C use probably played only minor roles in modulating TE in the face of variable soil fertility. The pronounced variation in TE resulted from a combination of the strong response of c sub(i)/c sub(a) to leaf N, and inherently high values of c sub(i)/c sub(a) for this tropical tree species; these two factors conspired to cause a 4-fold variation among treatments in (1-c sub(i)/c sub(a)), the term that actually modifies TE.

Individuals reproduce as males first and late in life as simultaneous hermaphrodites. I examined whether sex allocation (resources devoted to ova vs sperm) varies with group size in shrimps that have just matured as hermaphrodites. Focal males were reared with different numbers of hermaphrodites (1, 2, 5 or 10). Sperm stored in the ejaculatory ducts and eggs brooded underneath the abdomen were retrieved and weighted immediately after focal shrimps matured as hermaphrodites. Hermaphrodites should invest more into sperm with increasing group size to cope with more intense sperm competition. The proportion of focal shrimps that lost their first clutch of eggs after maturing as hermaphrodites increased with group size. This suggests male gender preferences by hermaphrodites experiencing large group sizes. No differences in sex allocation among group sizes were recorded for shrimps that did not lose their first clutch of eggs. Thus, group size does not affect sex allocation in terms of ova and sperm mass. This lack of phenotypic plasticity might be explained if sperm competition is not important in L. wurdemanni. It should not pay in terms of fitness for shrimps to produce and inseminate female-role hermaphrodites with large amounts of sperm when full paternity is assured in the absence of multi-male mating. In agreement with this idea, a second experiment demonstrated that female-role hermaphrodites invariably mated only once with a single other shrimp.

In less than 40 years C. mutica has spread throughout the northern hemisphere and the first recorded sighting in the southern hemisphere is reported here. Caprella mutica has been introduced to temperate oceanic coasts between latitudes of 25 and 70 N. Outside its native range, C. mutica has only been found in areas of human activity, including ports, aquaculture facilities and an oilrig; the species has not yet been found in natural habitats. Shipping and aquaculture transfers are the most likely long distance vectors; recreational boating and drifting weed are the most likely short distance vectors. Temperature and salinity do not explain the small-scale distribution of C. mutica on the west coast of Scotland; globally its annual temperature range is 0-22C. This suggests that the local scale distribution of C. mutica is potentially limited by the availability of suitable transportation vectors during the dispersal phase rather than by physical environmental factors following release.

Within the Alismatales, the order to which the Araceae belong, Z. zamiifolia is the only documented nonaquatic CAM species. Zamioculcas zamiifolia has weak CAM that is upregulated in response to water stress. In well-watered plants, day-night fluctuations in titratable acidity were 2.5 mu mol H super(+).(g fresh mass) super(-1), and net CO sub(2) uptake in the dark contributed less than 1% to daily carbon gain. Following 10 d of water stress, net CO sub(2) uptake in the light fell 94% and net CO sub(2) uptake in the dark increased 7.5-fold, such that its contribution increased to 19% of daily carbon gain. Following rewatering, dark CO sub(2) uptake returned to within 5% of prestressed levels. We postulate that CAM assists survival of Z. zamiifolia by reducing water loss and maintaining carbon gain during seasonal droughts characteristic of its natural habitat.

Inferences from multilocus DNA sequence data AN - 20207419; 7978013 AB - Phylogenetic information is useful in understanding the evolutionary history of adaptive traits. Here, we present a well-resolved phylogenetic hypothesis for Heliconius butterflies and related genera. We use this tree to investigate the evolution of three traits, pollen feeding, pupal-mating behaviour and larval gregariousness. Phylogenetic relationships among 60 Heliconiina species (86% of the subtribe) were inferred from partial DNA sequences of the mitochondrial genes cytochrome oxidase I, cytochrome oxidase II and 16S rRNA, and fragments of the nuclear genes elongation factor-1 alpha , apterous, decapentaplegic and wingless (3834 bp in total). The results corroborate previous hypotheses based on sequence data in showing that Heliconius is paraphyletic, with Laparus doris and Neruda falling within the genus, demonstrating a single origin for pollen feeding but with a loss of the trait in Neruda. However, different genes are not congruent in their placement of Neruda; therefore, monophyly of the pollen feeding species cannot be ruled out. There is also a highly supported monophyletic 'pupal-mating clade' suggesting that pupal mating behaviour evolved only once in the Heliconiina. Additionally, we observed at least three independent origins for larval gregariousness from a solitary ancestor, showing that gregarious larval behaviour arose after warning coloration.

Closure of these water-gates in response to increased atmospheric CO2 mixing ratio's, reduces transpiration under most laboratory and short term experimental conditions. Does this imply however, as atmospheric CO2 rises, and plant canopies expand, that evapo-transpiration (ETR), soil moisture content (SMC), and ecosystem water use efficiency (WUE) will increase? To test this question, field experiments have been and still are conducted using open top chambers. We have exposed native species in Florida Scrub to a carbon dioxide mixing ratio of nearly 700 ppmv CO2 for the past ten years and in Chesapeake Bay wetlands for 21 years. As a result of this treatment, in both ecosystems there was an increase in net ecosystem CO2 exchange and leaf area but a reduction of stomatal conductance, stem flow, transpiration, and ETR. For Florida scrub oak, these changes were also accompanied by an increase in soil moisture content as well.

In African elephants, sex-biased dispersal does not lead to the complete separation of male and female relatives, and so individuals may experience selection to recognize kin and avoid inbreeding. However, because estrous females are rare and male-male competition for mates is intense, the opportunity costs of inbreeding avoidance may be high, particularly for males. Here we combine 28 years of behavioural and demographic data on wild elephants with genotypes from 545 adult females, adult males, and calves in Amboseli National Park, Kenya, to test the hypothesis that elephants engage in sexual behaviour and reproduction with relatives less often than expected by chance. We found support for this hypothesis: males engaged in proportionally fewer sexual behaviours and sired proportionally fewer offspring with females that were natal family members or close genetic relatives (both maternal and paternal) than they did with nonkin. We discuss the relevance of these results for understanding the evolution of inbreeding avoidance and for elephant conservation.

We analyzed the effects of watershed use and estuarine characteristics on the spatial variation of SAV abundance among 101 shallow subestuaries of Chesapeake Bay during 1984- 2003. Areas of these subestuaries range from 0.1 to 101 km super(2), and their associated local watershed areas range from 6 to 1664 km super(2). Watershed land cover ranges from 6% to 81% forest, 1% to 64% cropland, 2% to 38% grassland, and 0.3% to 89% developed land. Landscape analyses were applied to develop a number of subestuary metrics (such as subestuary area, mouth width, elongation ratio, fractal dimension of shoreline, and the ratio of local watershed area to subestuary area) and watershed metrics (such as watershed area). Using mapped data from aerial SAV surveys, we calculated SAV coverage for each subestuary in each year during 1984-2003 as a proportion of potential SAV habitat (the area mixed-agricultural > agricultural > developed. Change-point analyses indicated strong threshold responses of SAV abundance to point source total nitrogen and phosphorus inputs, the ratio of local watershed area to subestuary area, and septic system density in the local watershed.

As part of continuing studies on the biogeochemical controls, sources, and fate of Hg and MeHg in the Chesapeake Bay region, we have recently expanded our research to examine Hg and MeHg cycling in Chesapeake tidal marshes. Our main study site is the Kirkpatrick Marsh, a salt marsh at the Smithsonian Environmental Research Center (SERC) on the shores of a Chesapeake Bay sub-estuary, the Rhode River. Kirkpatrick Marsh is dominated by Spartina patens, Scirpus olneyi, Phragmites australis, and several other species and is influenced by a mean tidal range of approximately 30 cm. The marsh is currently and has previously been the subject of various biogeochemical studies, thus basic biogeochemistry, carbon, and nutrient cycling for this system is well understood. Research goals for our study include an estimation of the contribution of salt marshes to MeHg budgets in the Chesapeake specifically and in coastal zones more generally; a first look at the sources of Hg for methylmercury production in tidal marshes; and an improved understanding of the biogeochemical controls on net MeHg production and flux in these wetlands. The research study has two major components. One is a spatially-distributed investigation of the geochemical and microbial controls on MeHg production in this high sulfate/high sulfide wetland system. Detailed biogeochemical measurements were made across three marsh zones distinguished by vegetation/elevation characteristics. Microbial activity in the three zones peaks at depths approximately equal to the mean water table depth, but always in the upper 5-10 cm of soil. Pore water sulfide concentrations increase substantially with depth in marsh soil cores, with highest sulfide concentrations (up to 1.5 M) found deeper in the least frequently flooded site. Initial data show that MeHg concentrations are maximal in the top 5-10 cm of soil, right above the transition into high sulfide zones. In contrast to some other marine systems, our initial data reveals high MeHg concentrations (up to 2.5 ng/L) in marsh pore water across a wider range of sulfide concentrations between 5 and 400 uM. The other component of this research is the construction of comprehensive and temporally-intensive water, total mercury, and methylmercury budgets for the salt marsh. This includes local Hg deposition, continuous flow- weighted Hg/MeHg flux measurements through the main tidal channel, monthly Hg/MeHg measurements along a salinity gradient in the adjacent Rhode River, and various other hydrologic and climatologic measurements. Initial results indicate, as expected, that the marsh is a major sink for particulate bound Hg. Linking process scale measurements with larger-scale hydrology is a key step in attributing the source/sink characteristics of the marsh to spatial and temporal variability of processes within it.

Stable isotopes may provide clues to help locate these nonbreeding populations. Previously, no valid records existed for the Coastal Plain Swamp Sparrow (Melospiza georgiana nigrescens) from October to late April. We used stable-isotope (C, N, and H) analyses to provide estimates of where molt occurs and then searched those areas for individuals of this species. The d13C and d15N of rump feathers were consistent with the Coastal Plain Swamp Sparrow molting in more saline marshes than the nominate subspecies after the breeding season, which confirms what was already known. The values for the same isotopes from crown feathers revealed that winter molt in the Coastal Plain Swamp Sparrow probably occurred in similar coastal brackish habitats. The dD of crown feathers indicated that prebreeding molt occurred at latitudes between South Carolina and Virginia. A subsequent search of this region located 18 Coastal Plain Swamp Sparrows, all of which were found in North Carolina or southeastern Virginia. Coastal Plain Swamp Sparrows were found predominantly in brackish marshes similar to their breeding habitat. On the basis of these observations, it appears that Coastal Plain Swamp Sparrows undergo a short southerly migration to a coastal region with substantially warmer winter conditions. This study is the first to make a specific geographic prediction based on stable-isotope analysis and to test the prediction in the field.

To test the first hypothesis, host strains differing in toxin content were inoculated with dinospores of Amoebophrya sp. derived from infected cultures of toxic and non-toxic K. veneficum, with resulting infections assessed following 24-h incubations. Contrary to expectations, infection of K. veneficum by Amoebophrya sp. was positively correlated with host toxicity. To examine the second hypothesis, synchronous infection with >80% of cells being parasitized was induced using a toxic strain of K. veneficum, and total toxin concentration (intracellular plus extracellular levels of KmTX1) was followed over the 3-day infection cycle. Toxin content ml super(-) super(1) increased with growth of K. veneficum in uninfected control cultures, but declined in infected cultures as the parasite completed its life cycle. On a cellular basis, toxin content of infected and uninfected cultures differed little during the experiment, suggesting that the parasite does not actively catabolise host toxin. Rather, infection appears to promote degradation of toxins via death of host cells and subsequent bacterial activity. Results indicate that Amoebophrya sp. ex K. veneficum has greater potential to impact toxic strains relative to non-toxic host strains in natural systems. Thus, Amoebophrya sp. ex. K. veneficum may limit the occurrence of toxic K. veneficum blooms in marine and estuarine environments, while simultaneously functioning as a pathway for dissipation of host toxin.

In this study, I explored multiple factors that theoretically affect fitness gain curves (that depict the relationship between sex-specific investment and fitness gains) to predict and test the overall and size-dependent sex allocation in a simultaneously hermaphroditic brooding shrimp with an early male phase. In Lysmata wurdemanni, sperm competition is absent as hermaphrodites reproducing in the female role invariably mated only once with a single other shrimp. Shrimps acting as females preferred small over large shrimps as male mating partners, male mating ability was greater for small compared to large hermaphrodites, and adolescent males were predominant in the population during the breeding season. In addition, brooding constraints were not severe and varied linearly with body size whereas the ability to acquire resources increased markedly with body size. Using sex allocation theory as a framework, the findings above permitted to infer the shape of the male and female fitness gain curves for the hermaphrodites. The absence of sperm competition and the almost unconstrained brooding capacity imply that both curves saturate, however the male curve levels off much more quickly than the female curve with increasing level of investment. In turn, the predominance of adolescent males in the population implies that the absolute gain of the female curve is greater than that of the male curve. Last, the size-dependent female preference and male mating ability of hermaphrodites determines that the absolute gain of the male curve is greater for small than for large hermaphrodites. Taking into consideration the inferred shape of the fitness gain curves, two predictions with respect to the optimal sex allocation were formulated. First, overall sex allocation should be female biased; it permits hermaphrodites to profit from the female function that provides a greater fitness return than the male function. Second, sex allocation should be size-dependent with smaller hermaphrodites allocating more than proportionally resources to male reproduction than larger ones. This size-dependent sex allocation permits hermaphrodites to profit from male mating opportunities that are the greatest at small body sizes. Size-dependent sex allocation is also expected because the male fitness gain curve decelerates more quickly than the female gain curve and experiments indicated that resources are greater for large than small hermaphrodites. These two predictions were tested when determining the sex allocation of hermaphrodites by dissecting their gonad and quantifying ovaries versus testes mass. Supporting the predictions above, hermaphrodites allocated, on average, 118 times more to the female than to the male gonad and the proportion of resources devoted to male function was higher in small than in large hermaphrodites. A trade-off between male and female allocation is assumed by theory but no negative correlation between male and female reproductive investment was observed.

CAIs 100, 160, 6-1-72, and 3529-40 consist of Al,Ti-diopside (fassaite; 13-23 wt% Al (sub 2) O (sub 3) , 2-14 wt% TiO (sub 2) ), Na-bearing aakermanitic melilite (0.1-0.4 wt% Na (sub 2) O; Ak (sub 30-75) ), spinel, and fine-grained ( approximately 5-10 mu m) anorthite groundmass. Most of the fassaite and melilite grains have "lacy" textures characterized by the presence of abundant rounded and prismatic inclusions of anorthite approximately 5-10 mu m in size. Lacy melilite is pseudomorphed to varying degrees by grossular, monticellite, and pure forsterite or wollastonite. CAI 6-1-72 contains a relict Type B CAI-like portion composed of polycrystalline gehlenitic melilite (Ak (sub 10-40) ), fassaite, spinel, perovskite, and platinum-group element nuggets; the Type B-like material is overgrown by lacy melilite and fassaite. Some melilite and fassaite grains in CAIs 100 and 160 are texturally similar to those in the Type B portion of 6-1-72. CAIs ABC and TS26 contain relict chondrule fragments composed of forsteritic olivine and low-Ca pyroxene; CAI 93 is overgrown by a coarse-grained igneous rim of pigeonite, augite, and anorthitic plagioclase. These three CAIs contain very sodium-rich aakermanitic melilite (0.4-0.6 wt% Na (sub 2) O; Ak (sub 63-74) ) and Cr-bearing Al,Ti-diopside (up to 1.6 wt% Cr (sub 2) O (sub 3) , 1-23 wt% Al (sub 2) O, 0.5-7 wt% TiO (sub 2) ). Melilite and anorthite in the Allende Type C CAI peripheries are replaced by nepheline and sodalite, which are crosscut by andradite-bearing veins; spinel is enriched in FeO. The CAI fragment CG5 is texturally and mineralogically distinct from other Allende Type Cs. It is anorthite-poor and very rich in spinel poikilitically enclosed by Na-free gehlenitic melilite (Aak (sub 20-30) ), fassaite, and anorthite; neither melilite nor pyroxene have lacy textures; secondary minerals are absent. The Al-rich chondrules 3655b-2 and 3510-7 contain aluminum-rich and ferromagnesian portions. The Al-rich portions consist of anorthitic plagioclase, Al-rich low-Ca pyroxene, and Cr-bearing spinel; the ferromagnesium portions consist of fosteritic olivine, low-Ca pyroxene, and opaque nodules. We conclude that Type C CAIs 100, 160, 6-1-72, and 3529-40 formed by melting of coarse-grained Type B-like CAIs which experienced either extensive replacement of melilite and spinel mainly by anorthite and diopside (traces of secondary Na-bearing minerals, e.g., nepheline or sodalite, might have formed as well), or addition of silica and sodium during the melting event. CG5 could have formed by melting of fine-grained spinel-melilite CAI with melilite and spinel partially replaced anorthite and diopside. CAIs ABC, 93, and TS-26 experienced melting in the chondrule-forming regions with addition of chondrule-like material, such as forsteritic olivine, low-Ca pyroxene, and high-Ca pyroxene. Anorthite-rich chondrules formed by melting of the Al-rich (Type C CAI-like) precursors mixed with ferromagnesian, Type I chondrule-like precursors. The Allende Type C CAIs and Al-rich chondrules experienced fluid-assisted thermal metamorphism, which resulted in pseudomorphic replacement of melilite and anorthite by grossular, monticellite, and forsterite (100, 160, 6-1-72, 3592-40) or by grossular, monticellite, and wollastonite (ABC, 93, TS-26). The pseudomorphic replacement was followed or accompanied by iron-alkali metasomatic alteration resulting in replacement of melilite and anorthite by nepheline and sodalite, enrichment of spinel in FeO, and precipitation of salite-hedenbergite pyroxenes, wollastonite, and andradite in fractures and pores in and around CAIs.

During the Cambrian they had a wide distribution coinciding with trilobite realms. This pattern may be related to the breakup of a Neoproterozoic supercontinent, probably Pannotia, which implies that naraoiids originated before the Cambrian- "explosion." Based on new observations on the original material from the Burgess Shale (Middle Cambrian, British Columbia), Naraoia halia is reconsidered as a valid species. The validity is further confirmed by a new record of the occurrence of this species in the Chengjiang Lagerstatte (Lower Cambrian, China). In addition, some structures of N. compacta of the Burgess Shale have been reinterpreted. Two more naraoiid species are redescribed in detail from the Chengjiang Lagerstatte on the basis of more than 1,000 well-preserved specimens. Naraoia spinosa shows dimorphism and Misszhouia longicaudata exhibits geographical variation in the overall shape of the dorsal exoskeleton. Naraoiids may have a protaspis-like larva, but the previously assigned protaspis has proven to be a separate taxon, Primicaris. In dorsal view, naraoiids resemble a giant "degree 0" meraspis (i.e., without thorax), and could have originated from different heterochronic processes, neoteny or hypermorphosis. Naraoiids are generally accepted as vagrant benthos. A predatory/scavenging life mode is supported by functional morphology and recent analogues. A healed injury in M. longicaudara suggests that they could be the prey of larger predators, most likely anomalocaridids. We suggest that differences in exopod composition might represent evolutionary changes through the Early-Middle Cambrian. The monophyly of the Naraoiidae is not firmly established. Similarity to liwiids, supposed to be the close relatives of naraoiids, is limited to overall shape. We exclude naraoiids from the Trilobita, though there do exist a number of similarities between them.

Using a literature survey and new palynological data from LM and SEM studies, the pollen of a number of "rogue genera" was described and compared with that of potential related taxa in Compositae. Rogue genera are defined as taxa that have traditionally been difficult to classify, usually having highly divergent macro-morphological characters compared to the rest of Compositae. They include genera of known tribe but unknown position within that tribe and genera or small tribes of uncertain position in Compositae, as well as taxa that have recently been placed using molecular data but whose morphology continues to intrigue synantherologists. In the majority of cases, palynology was found to provide new sets of characters which could be compared to the robust hypothesis of relationships shown in the recent DNA-based supertree. Pollen variously provided support and diagnostic characters for some groups (e.g. Hesperomannia, Hoplophyllum, Eremothamnus, Tarchonantheae, Corymbieae and Gymnarrheneae), suggested some possible affinities for taxa currently excluded from phylogenetic studies using DNA (such as Moquinia, Catananche, Pacourina and Platycarpha), or to some degree contradicted existing phylogenies (e.g. Gundelia and Warionia), suggesting areas for future research.

To understand the history of water on Mars, we take a close look at key locations with the High-Resolution Imaging Science Experiment on board the Mars Reconnaissance Orbiter, reaching fine spatial scales of 25 to 32 centimeters per pixel. Boulders ranging up to approximately 2 meters in diameter are ubiquitous in the middle to high latitudes, which include deposits previously interpreted as fine-grained ocean sediments or dusty snow. Bright gully deposits identify six locations with very recent activity, but these lie on steep (20 degrees to 35 degrees ) slopes where dry mass wasting could occur. Thus, we cannot confirm the reality of ancient oceans or water in active gullies but do see evidence of fluvial modification of geologically recent mid-latitude gullies and equatorial impact craters.

Previous investigations of infant weaning patterns at the Dakhleh Oasis, Egypt, relied on cross-sectional isotope data. In this study, we re-examine this weaning pattern, using a simulated longitudinal approach, which does not require any assumptions regarding potential infant mortality biases. This involves examining the dental isotopic signatures of individuals who survived the weaning process. Stable isotope signatures from juveniles and adults (102 individuals, 297 teeth) were examined to reconstruct the weaning history of those that survived the weaning process. Both deciduous and permanent teeth were sampled. Homogenized enamel and dentin samples were isolated from each tooth and analyzed for [delta]13Cap and [delta]18Oap from the enamel and [delta]15Ncoll and [delta]13Ccoll from dentin collagen. We investigate differences between in in utero versus postbirth, preweaning versus postweaning, and juvenile versus adult stable isotope values as reflected in the dentition. A random permutation procedure was used to test for statistically significant differences in stable isotope values between tooth types. Statistically significant differences were observed in all stable isotopes between permanent and deciduous teeth, and between early and later forming permanent teeth in [delta]13Cap and [delta]15Ncoll isotopes. These results indicate dietary change between in utero and postbirth, and changes occurring during the weaning period. These results provide a more comprehensive picture of infant weaning practices at Kellis and provide further support that complete weaning occurred by 3 years of age. Copyright John Wiley & Sons.

Nodipecten magnificus and Leopecten isabelensis n. sp. are neoendemic species that evolved in the Pliocene from ancestors in the tropical eastern Pacific and more remote ancestors in the Tertiary Caribbean Province before closure of transisthmian seaways. Spathochlamys vestalis, an eastern Pacific species whose incipiently neoendemic Galapagos representatives have diverged only slightly from the mainland stock, is related to an extant, broadly distributed western Atlantic sister species, S. benedicti, which has an ancestry traceable back to the Miocene in the Tertiary Caribbean Province. Euvola galapagensis is a paleoendemic whose ancestral lineage is extinct on mainland coasts. Veprichlamys incantata is a paleoendemic with an exclusively Pacific history, with its probable immediate ancestor occurring in the Pliocene of Ecuador and its more remote Miocene ancestors in the cooler waters of the southeastern Pacific. The high frequency of endemism and the evidence that originations are Pliocene or later are consistent with the high rates of morphological evolution attained by the Pectinidae relative to many other bivalves.New species described are L. isabelensis of the Galapagos Islands and L. cocosensis of Cocos Island. Leopecten is shown to be restricted to the Americas and to differ morphologically from Flabellipecten, an extinct Neogene European genus that is phylogenetically not closely related. Based on a new phylogeny, the genus Lyropecten is extinct, and living representatives of the Lyropecten-Nodipecten clade are all in the genus Nodipecten.

Assessment methods relying on maps rather than field sampling (level 1 assessment) are often expert systems summarizing the best professional judgments of wetland scientists. We instead developed level 1 assessment relationships by statistically analyzing results from field sampling. The field campaign applied the hydrogeomorphic (HGM) functional assessment approach to sample 143 freshwater flat and riverine wetlands in the Nanticoke River watershed, Maryland and Delaware, USA. Functional condition index (FCI) scores for five wetland functions were calculated from the field observations. We used geographic information system (GIS) analysis of digital maps to derive candidate landscape indicators for the sampled points. We tested which indicators correlated strongly with the field condition scores, and then we used stepwise multiple regression and regression tree analysis to identify the most effective combinations of landscape metrics for predicting the condition measurements. The best multiple regressions combined information from land-cover, road, and stream maps, especially a stream map resolving natural stream reaches from channelized or ditched reaches. For riverine wetlands, we obtained statistically significant regressions explaining 63%-85% of the variance of measured FCI scores for all five HGM functions (hydrology, biogeochemistry, habitat, plant community, and landscape). Comparable models for flat wetlands were also statistically significant but explained less (48%-54%) of the variance. Regression tree analysis produced more parsimonious models than did stepwise multiple regression. A tree model explained the same amount of variability as the multiple regression model for two flat and two riverine functions, but the tree model explained less variability for two flat and three riverine functions. Our level 1 relationships can be applied to estimate condition scores for unsampled wetlands and to provide confidence limits for those estimates. The uncertainty in predicting a condition scores for individual assessment points is high for most HGM functions, but the models can still help prioritize field visits to select sites for management action. Confidence limits are narrower for predicting mean scores across many wetlands, so the relationships are more powerful for predicting average wetland condition across an assessment area, such as a watershed.

However, one important N-removal process, denitrification, can produce the atmospheric pollutant nitrous oxide (N sub(2)O). Wetland biogeochemical functions, such as N processing, can be assessed by the hydrogeomorphic (HGM) approach using a suite of simple field observations made in a single visit to a wetland. HGM assessments score functions on a scale of 0-1 where 1 equals the functionality of an undisturbed reference standard wetland and 0 equals the functionality of a completely degraded wetland. We compared seasonal measurements of potential denitrification, N sub(2)O emissions, and related soil characteristics to HGM assessments of nine non-tidal riverine wetlands and seven flats wetlands in the Nanticoke River watershed in Delaware and Maryland, USA. Denitrification potential, measured as denitrification enzyme activity (DEA), was higher in riverine wetlands than in flats. DEA increased with increases in percent water-filled pore space, pH, ammonium concentration, and the percentages of N and organic carbon. DEA decreased with increases in oxidation-reduction potential (E sub(h)) and water-table depth. The difference in DEA between riverine and flats wetlands was attributable to the differences in the correlated soil characteristics. N sub(2)O emission rates were higher on average in riverine wetlands than in flats, but the difference was not statistically significant. N sub(2)O emission rates were generally less predictable than DEA and showed only weak correlations with pH, water-table depth, and the percentage of water-filled pore space when data from riverine wetlands and flats were combined. HGM biogeochemistry function scores ranged from 0.18 to 1 for the riverine wetlands and from 0.24 to 0.98 for the flats. The scores did not correlate with N sub(2)O emission or DEA, except for summer DEA in flats, which increased with increasing score. Wetland alterations that increase soil moisture relative to reference standard conditions decrease biogeochemistry and hydrology function scores but increase DEA. Biogeochemistry function scores would more closely reflect denitrification potential if the scoring incorporated measurements of soil characteristics that correlate with DEA.

We found degradation of wetland functions below reference standard levels for the majority of wetlands in both classes. Wetland condition was also related to the level of disturbance in both wetland classes. In flats, the most common disturbances were associated with hydrologic and vegetation modifications. Flat wetlands with low HGM function scores for the Plant Community and Habitat functions had almost all been converted from hardwood forest to Loblolly pine plantations. Most modifications associated with riverine wetlands were associated with stream channelization. Results of this study demonstrate that a site-specific and reference-based approach to assessment (i.e., the HGM method) can successfully be applied at the scale of an entire watershed if it is combined with a sampling approach that allows sites to be selected without geographic bias. The approach can also be used to determine if wetland functions vary from one sub-basin to another, and results of this project can be used by managers to begin to develop strategies for restoration of wetland functions at the watershed scale.

Many marine mangrove islands are located in the shallow backwaters of coral reefs in Belize and elsewhere in the Caribbean and have a mean tidal range of only 15 cm. They are densely populated by sponges, mostly attached to subtidal red-mangrove stilt roots and peat banks lining tidal channels. Some species are endemic to mangroves, others are immigrants from nearby reefs. Mangrove endemics endure environmental hardships, such as occasional exposure to air during spring tides, temperature and salinity extremes, fine sediments, even burial in detritus. Reef immigrants into mangroves enjoy protection from spongivores that do not stray into the swamp but they eventually succumb to environmental stress. There is evidence exemplified by the common demosponge Chondrilla aff. nucula, that sponges flourishing in both mangrove and reef habitats may develop separate ecologically specialized and reproductively isolated populations. Such processes can lead to genetic modifications and thus serve as mechanisms for ecological speciation. Because Chondrilla nucula Schmidt was first described from the Mediterranean Sea, it was long suspected that the western Atlantic population may be a separate species. New morphological and molecular evidence prompt us to describe it under a new name, Chondrilla caribensis, with two ecological forms, forma caribensis from mangroves and lagoons, and forma hermatypica from open reefs.

The pattern and probability of successful dispersal among habitats can therefore be crucial in determining whether local populations will become rare or increase in abundance. We present here data on the dispersal strategy and population dynamics of three marine amphipods living in pen shells (Atrina rigida) in the Gulf of Mexico. The three amphipod species in this study disperse at different life stages. Neomegamphopus hiatus and Melita nitida disperse as adults, while Bemlos unicornis disperses as juveniles. The two species that disperse as adults have the highest initial population sizes when a new shell becomes available, likely caused by the arriving females releasing their brood into these recently occupied shells. This dispersal pattern results in initially higher population growth, but fewer occupied shells, as noted by their clumped distribution. In contrast, the species that disperses as juveniles accumulates more slowly and more evenly across habitats, eventually dominating the other two in terms of numerical abundance. The metapopulation dynamics of the three species seems to be highly dependent on the life history stage involved in dispersal.

While nutrient availability can affect many ecological processes, here we investigate how N and P enrichment interact with forest structure in three distinct zones (fringe, transition, dwarf) to alter patterns of herbivory as a function of folivory, loss of yield, and tissue mining. The effects of nutrient addition and zone varied by functional feeding group or specific herbivore. Folivory ranged from 0 to 0.4% leaf area damaged per month, but rates did not vary by either nutrient enrichment or zone. Leaf lifetime damage ranged from 3 to 10% of the total leaf area and was caused primarily by the omnivorous tree crab Aratus pisonii. We detected two distinct spatial scales of response by A. pisonii that were unrelated to nutrient treatment, i.e., most feeding damage occurred in the fringe zone and crabs fed primarily on the oldest leaves in the canopy. Loss of yield caused by the bud moth Ecdytolopha sp. varied by zone but not by nutrient treatment. A periderm-mining Marmara sp. responded positively to nutrient enrichment and closely mirrored the growth response by Rhizophora mangle across the tree height gradient. In contrast, a leaf-mining Marmara sp. was controlled by parasitoids and predators that killed >89% of its larvae. Thus, nutrient availability altered patterns of herbivory of some but not all mangrove herbivores. These findings support the hypothesis that landscape heterogeneity of the biotic and abiotic environment has species-specific effects on community structure and trophic interactions. Predicting how herbivores respond to nutrient over-enrichment in mangrove ecosystems also requires an assessment of habitat heterogeneity coupled with feeding strategies and species-specific behavior measured on multiple scales of response.

Experimental structures (casita frame, mesh-roof casita and full-roof casita) were successful in attracting and aggregating predators as hypothesized, with those structures providing more overhead cover attracting significantly more predators. Although many predators, including the numerically dominant spiny lobster Panulirus argus, preyed heavily on or included molluscs in their diets, no significant impacts of predation by spiny lobsters and finfishes on the abundance and species richness of the molluscan assemblage were observed. Regional differences in prey abundance and richness were significant, yet predator effects were similar between locations. Significant location differences in prey abundances, therefore, did not result from differential impacts of prey consumption by casita-associated predators. Predation effects by spiny lobsters and various species of finfishes in Florida Bay were dispersed over time and space and predation was not the primary structuring mechanism for the gastropod and bivalve assemblages in these seagrass and macroalgal habitats. Measurable differences between prey populations in the 2 study locations probably reflect differences in habitat heterogeneity, spatial and temporal variability in predator and prey abundances and distributions, overall high diversity of benthic prey, and ontogenetic shifts in diet and habitat use by predators, all which tend to buffer predatory impacts.

Although the Gulf's aquatic bird populations have been remarked upon by ornithologists for over 50 years, nesting populations have been neither systematically studied nor completely characterized. In 2005 and 2006, the entire Gulf of Panama was inventoried to document the nesting status of seabirds and other colonial waterbirds. Over 50,000 birds of 20 species nesting at 57 sites were documented. Seabirds nested during the dry season, the period of oceanographic upwelling. Coastal colonial waterbirds nested at the end of the dry season and in the early wet season, when inland feeding habitats were optimal. Brown Pelicans (Pelecanus occidentalis) were the most numerous seabird with over 4,800 nests and 10,000 individuals counted. Over 3,600 Neotropic Cormorant (Phalacrocorax brasilianus) nests and over 2,200 Magnificent Frigatebird (Fregata magnificens) nests were documented. Cattle Egrets (Bubulcus ibis) were the most abundant colonial wading birds, followed by Great Egrets (Ardea alba). Great Egrets were the first wading birds to nest, Cattle Egrets the last. Seven sites contained over 1,000 nests. Colony locations and numbers differed markedly from the historic literature. Some historic information is erroneous, but other differences reflect changes in distribution. More nesting Brown Pelicans and Sooty Terns (Sterna fuscata) and fewer Neotropic Cormorants were found than expected from the literature. New sites documented included some of global or regional conservation importance. This paper presents the first breeding records for Panama of Little Blue Heron (Egretta caerulea), Glossy Ibis (Plegadis falcinellus), and Bridled Tern (Sterna anaethetus), and third record for Cocoi Heron (Ardea cocoi). There is no evidence for long-term declines of seabirds or colonial wading birds in the Gulf of Panama. Populations reaching conservation thresholds globally or biogeographically include Brown Pelican, Bare-throated Tiger-Heron (Tigrisoma mexicanum), White Ibis (Eudocimus albus), Glossy Ibis, and Bridled Tern. The Black-crowned Night-Heron (Nycticorax nycticorax) exceeded conservation thresholds for Central America. Six new sites of global importance for bird conservation were identified and the continued importance of another site confirmed. The continued health of the waterbird populations of Panama will depend on environmental education and protection of important colony sites from disturbance and development.

Pots containing either bare C sub(4)-derived soil or the C sub(3) sedge Scirpus olneyi planted in C sub(4)-derived soil were incubated in greenhouse chambers at either ambient or twice-ambient atmospheric CO sub(2). We measured CO sub(2) flux from each pot, quantified soil organic matter (SOM) mineralization using delta super(13)C, and determined root and shoot biomass. SOM mineralization increased in response to elevated CO sub(2) by 83-218% (P<0.0001). In addition, soil redox potential was significantly and positively correlated with root biomass (P= 0.003). Our results (1) show that there is a positive feedback between elevated atmospheric CO sub(2) concentrations and wetland SOM decomposition and (2) suggest that this process is mediated by the release of oxygen from the roots of wetland plants. Because this feedback may occur in any wetland system, including peatlands, these results suggest a limitation on the size of the carbon sink presented by anaerobic wetland soils in a future elevated-CO sub(2) atmosphere.

The legislation focused primarily on reducing the transfer of non-indigenous organisms in ships' ballast water. Ballast water is used by commercial ships to maintain trim and stability during voyages. Ballast is taken on from surrounding waters, stored in dedicated ballast tanks, and discharged at subsequent ports of calls, resulting in the unintentional but massive transfer of organisms on a global scale. We focused specifically on characterizing what is known about (1) effects of BWE in reducing the concentration of coastal organisms in ballast tanks, (2) changes in ballast water management over time, and (3) temporal changes in invasion history, describing the number of non-indigenous species established coincident with ballast water management. This analysis is divided among multiple chapters, produced by various combinations of authors to examine these specific issues in the respective ecosystems, the Great Lakes and Chesapeake Bay.

Patterns of naticid predation in a fossil molluscan assemblage were studied by examination of drilling frequencies in a series of samples collected at three sites of the Gatun Formation (late Middle Miocene), Panama. Overall drilling intensities were relatively low (18 %) and were not correlated with abundance. Turritellids, turrids, and terebrids (making up to 11 % of the studied fauna) were the most consumed, representing almost 29 % of the total prey. Especially important were turritellids representing over 20 % of the total consumed prey. Albeit abundant (54 % of the studied fauna), columbellids, cerithiids, and marginellids showed low drilling intensities (8.2-10.4 %). Naticids were the major predators. Con-familial drilling among naticids is high and did not seem to be related to absence of preferred prey. Consistent with other studies, these data indicate that predators demonstrate high prey selectivity.

Albatross are among the largest seabirds. The great, wandering and royal albatrosses have the widest wing span-ten feet or more-of any living bird. Albatross are the masters of soaring flight, able to glide over vast tracts of ocean without flapping their wings. The birds typically choose their direction 24 hours prior to the arrival of the system, suggesting that they can respond to barometric cues. Many fisheries have adopted ingenious methods to reduce injuring and killing seabirds-or attracting them to boats. It is concluded that the supply of discarded fish reduces competition for food between and within albatross species and provides an alternative food source to predatory birds such as skua.

AN - 70648408; 17549547 AB - Contamination of wetlands by lead shot and lead fishing weights has generated a tremendous amount of research into the impact of lead poisoning on wildlife. Less well known are the potential threats to wildlife posed by lead contaminants still prevalent in urban environments. Despite a U.S. federal ban on lead-based paint and gasoline in 1978 and 1986, respectively, lead residue is still prevalent at hazardous levels in urban and suburban environments and may present a health concern for people and wildlife, particularly birds. We quantified soil lead content in residential properties across a rural-to-urban land-use gradient in the metropolitan Washington, D.C. area and then assessed the impact of lead contamination on body condition in adult and nestling passerine birds at the same sites. Soil lead concentration was significantly higher in urban sites compared to rural sites. Accordingly, adult and nestling birds captured in urban sites had significantly higher blood lead concentrations than their rural counterparts. However, only gray catbird nestlings exhibited lower body condition as a result of lead contamination. Birds continue to breed in urban habitats despite numerous negative attributes to these environments including light, noise, pedestrian and toxic contaminants, such as lead. These sites often contain habitat that appears suitable for roosting, nesting, and foraging and thus may act as an ecological trap for breeding birds because breeding success is often negatively associated with increasing urbanization. Lead contamination is one more feature of urbanization that birds and other wildlife must face in an increasingly developed world.

One area where all space flight visionaries failed to make meaningful predictions was in the rapidly advancing capabilities of robotics and electronics. For example, when Arthur C. Clarke envisioned geosynchronous telecommunications satellites in 1945 he believed that they would require humans working onboard. It is, therefore, easy to conceive of the motivation that led people like Clarke and Wernher von Braun to imagine the necessity to station large human crews in space. In this instance some of the most forward-thinking space flight advocates utterly failed to anticipate the electronics/digital revolution then just beginning. Humans, space flight visionaries always argued, were a critical element in the exploration of the solar system and ultimately beyond. Human destiny required our movement beyond this planet, ultimately to the colonization of the galaxy as a means of assuring the survival of the species. With the rapid advance of electronics in the 1960s, however, some began to question the role of humans in space exploration. It is much less expensive and risky to send robot explorers than to go ourselves. This debate reached saliency early on and became an important part of the space policy debate late in the twentieth century. The paper describes the history and an analysis of how we arrived at this point in human space flight, as well as the relative merits of human versus robotic space exploration. In essence, the old paradigm for human exploration-ultimately becoming an interstellar species-is outmoded and ready for replacement. This paper looks to the future of humans and robots in space, and suggests that it is conceivable that a post-human cyborg species may develop in a future extraterrestrial environment.

The CAIs consist of lath-shaped anorthite (An (sub 99) ), Cr-bearing Al-Ti-diopside (Al and Ti contents are highly variable), spinel, and highly aakermanitic and Na-rich melilite (Aak (sub 63-74) , 0.4-0.6 wt% Na (sub 2) O). TS26 and 93 lack Wark-Lovering rim layers; ABC is a CAI fragment missing the outermost part. The peripheral portions of TS26 and ABC are enriched in SiO (sub 2) and depleted in TiO (sub 2) and Al (sub 2) O (sub 3) compared to their cores and contain relict ferromagnesian chondrule fragments composed of forsteritic olivine (Fa (sub 6-8) ) and low-Ca pyroxene/pigeonite (Fs (sub 1) Wo (sub 1-9) ). The relict grains are corroded by Al-Ti-diopside of the host CAIs and surrounded by haloes of augite (Fs (sub 0.5) Wo (sub 30-42) ). The outer portion of CAI 93 enriched in spinel is overgrown by coarse-grained pigeonite (Fs (sub 0.5-2) Wo (sub 5-17) ), augite (Fs (sub 0.5) Wo (sub 38-42) ), and anorthitic plagioclase (An (sub 84) ). Relict olivine and low-Ca pyroxene/pigeonite in ABC and TS26, and the pigeonite-augite rim around 93 are (super 16) O-poor (Delta (super 17) O approximately -1 per mil to -8 per mil). Spinel and Al-Ti-diopside in cores of CAIs ABC, TS26, and 93 are (super 16) O-enriched (Delta (super 17) O down to -20 per mil), whereas Al-Ti-diopside in the outer zones, as well as melilite and anorthite, are (super 16) O-depleted to various degrees (Delta (super 17) O = -11 per mil to 2 per mil). In contrast to typical Allende CAIs that have the canonical initial (super 26) Al/ (super 27) Al ratio of approximately 5X10 (super -5) , ABC, 93, and TS26 are (super 26) Al-poor with ( (super 26) Al/ (super 27) Al)0 ratios of (4.7+ or -1.4)X10 (super -6) , (1.5+ or -1.8)X10 (super -6) , and <1.2X10 (super -6) , respectively. We conclude that ABC, TS26, and 93 experienced remelting with addition of ferromagnesian chondrule silicates and incomplete oxygen isotopic exchange in an (super 16) O-poor gaseous reservoir, probably in the chondrule-forming region. This melting episode could have reset the (super 26) Al- (super 26) Mg systematics of the host CAIs, suggesting it occurred approximately 2 Myr after formation of most CAIs. These observations and the common presence of relict CAIs inside chondrules suggest that CAIs predated formation of chondrules.

The results reveal the exceptional mineralogical and compositional heterogeneity of this material at the sub-mu m level. We observe mu m-scale and sub-mu m grains with elemental associations suggesting feldspar, metal with widely varying Ni contents, and a Cr-Fe alloy (in addition to forsterite, pyroxene, sulfide, ferrihydrite, and amorphous groundmass previously described). A new class of mu m-scale CAI (mu CAI) is also observed, which show sub-mu m compositional zoning, and a range of oxygen isotopic compositions. Unlike the larger CAIs in Acfer 094, which are uniformly (super 16) O-enriched, two of the three mu CAIs we analyzed are isotopically normal. We also observed a Li-rich hotspot that detailed analysis by ToF-SIMS suggests may be a LiCr-oxide grain. Within the resolution of the NanoSIMS, this grain has isotopically normal Li. Finally, in our 50X50 mu m area, we positively identified a presolar grain that is the most (super 18) O-rich silicate found so far in meteorites. The grain may originate from an asymptotic giant branch (AGB) star, or more likely, a supernova. In line with previous TEM studies (Greshake 1997), we find no evidence for clastic material (e.g., fragmental chondrules) in the matrix of Acfer 094: although the matrix is volatile-depleted, this depletion does not appear to result from dilution of a primordial starting material with (depleted) chondrule fragments. Assuming that matrix experienced the depletion event, our data on the detailed mineralogy of Acfer 094 are currently equivocal in constraining the nature of that event. We observe carrier phases for several elements consistent with conditions approaching equilibrium condensation; however, the presence of an amorphous groundmass is suggestive of more rapid cooling.
