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.

Seven deep-water coral sites (384-756 m), located between Cape Lookout, NC, and Cape Canaveral, FL, were sampled in June 2004 using a manned submersible. The presence of regenerative tissue was evaluated by visual inspection of each individual ophiuroid, and the proportion of regenerating arms per individual was examined relative to size of individual, geographic location, and depth of collection. Ophiacantha bidentata, the dominant brittle star collected, commonly displayed signs of sublethal injury with over 60% of individuals displaying some evidence of regeneration. These levels of regeneration rival those reported for shallow-water ophiuroids. Larger individuals (>6.5 mm disc size) had a higher incidence of regeneration than smaller individuals. Size of individual and percent of regeneration were negatively correlated with depth. Although O. bidentata was significantly less abundant in southern versus northern sites, ophiuroid abundance did not appear to be influenced by amount or density of coral substratum. Presence of dense aggregations of O. bidentata indicates that they are an important component of the invertebrate assemblage associated with deep-water coral habitat especially in the northern part of the study area. Assuming that observed frequencies of injury and subsequent regeneration represent predation events then dense ophiuroid aggregations in deep-water coral habitats represent an important renewable trophic resource within these communities.

Coffee certification programs may offer one way to protect biodiversity and maintain farmer livelihoods. Established coffee certification programs fall into three distinct, but not mutually exclusive categories: organic, fair trade, and shade. The results of previous studies demonstrate that shade certification can benefit biodiversity, but it remains unclear whether a farmer's participation in any certification program can provide both ecological and economic benefits. To assess the value of coffee certification for conservation efforts in the region, we examined economic and ecological aspects of coffee production for eight coffee cooperatives in Chiapas, Mexico, that were certified organic, certified organic and fair trade, or uncertified. We compared vegetation and ant and bird diversity in coffee farms and forests, and interviewed farmers to determine coffee yield, gross revenue from coffee production, and area in coffee production. Although there are no shade-certified farms in the study region, we used vegetation data to determine whether cooperatives would qualify for shade certification. We found no differences in vegetation characteristics, ant or bird species richness, or fraction of forest fauna in farms based on certification. Farmers with organic and organic and fair-trade certification had more land under cultivation and in some cases higher revenue than uncertified farmers. Coffee production area did not vary among farm types. No cooperative passed shade-coffee certification standards because the plantations lacked vertical stratification, yet vegetation variables for shade certification significantly correlated with ant and bird diversity. Although farmers in the Chiapas highlands with organic andor fair-trade certification may reap some economic benefits from their certification status, their farms may not protect as much biodiversity as shade-certified farms. Working toward triple certification (organic, fair trade, and shade) at the farm level may enhance biodiversity protection, increase benefits to farmers, and lead to more successful conservation strategies in coffee-growing regions.

The first pulse was concentrated during the latest Silurian to Early Devonian (417 to 403 Ma), and consists of the earliest evidence for consumption of sporangia and stems (and limited fungivore borings). Herbivorization of most of these tissues was rapid, representing 0 to 20 million-year (m.y.) lags from the earliest occurrences of these organs in the fossil record to their initial consumption (Phase 1). For approximately the next 75 m.y., there was a second, more histologically varied origination and expansion of roots, leaves, wood and seeds, whose earliest evidence for herbivorization occurred from the Middle-Late Mississippian boundary to the Middle Pennsylvanian (327 to 309 Ma). The appearance of this second herbivory pulse during the later Paleozoic (Phase 2) is accompanied by major lags of 98 to 54 m.y. between times of appearance of each of the four organ and tissue types and then-subsequent herbivory. Both pulses provide a context for three emerging questions. First is an explanation for the contrast between the near instantaneous consumption of plant tissues during Phase 1, versus the exceptionally long lags between the earliest occurrences of plant tissues and their subsequent herbivorization during Phase 2. Second is the identity of arthropod herbivores for both phases. Third is the cause behind the overwhelming targeting of seed-fern plant hosts during Phase 2. Regardless of the answers to these questions, the trace fossil record of plant-arthropod associations provides primary ecological data that remain unaddressed by the body-fossil record alone.

Geomagnetic polarity reversals between chrons C26r, C26n, C25r, C25n, C24r, and C24n have been identified among multiple stratigraphic sections in different parts of the basin. Using the new magnetostratigraphic framework, paleontological, paleobotanical, and isotopic information from these varied locations in the basin can now be correlated and compared to similar records from elsewhere in the world. These new data resolve previous uncertainty concerning the timing of an important episode of faunal turnover known as Biohorizon B, which is slightly below the chron C24r-C24n boundary, close to the position of the Elmo isotope excursion in marine records. Backstripping analysis using these new magnetostratigraphic data helps define the time-transgressive onset of basin formation and shows the different subsidence histories of the northern and southern parts of the basin.

For the dynamic crystallization experiments, we cooled from both liquidus and subliquidus peak temperatures (T (sub max) ), at cooling rates from 5-1000 degrees C/h. The starting compositions include two with anorthite and two with forsterite as the dominant liquidus phases, all at or near spinel-saturation. One of each pair evolves towards diopside crystallization, and the others cordierite or enstatite crystallization, giving a total of four completely different crystallization sequences analogous to the four basic varieties of Al-rich chondrule recently proposed. Bulk composition is the main controlling factor, both in terms of mineralogy and texture. The textures of the anorthite-rich compositions are more sensitive to T (sub max) than they are to cooling rate, whereas the textures of the forsterite-rich compositions are more sensitive to cooling rate. Comparisons of natural Al-rich chondrules having similar compositions to our synthetic analogues indicate that the natural objects reflect a range of peak heating temperatures, approximately 1400-1500 degrees C, and cooling rates of 10-500 degrees C/h for porphyritic chondrules and possibly higher (1000 degrees C/h) for barred chondrules. These conditions are consistent with the conditions inferred for ferromagnesian chondrules but differ from those inferred for some calcium-aluminum-rich inclusions.

Despite its prominent role in a number of evolutionary studies, species identification in this genus is often difficult and phylogenetic relationships among its species are not well understood. Here I present the findings from a comprehensive study of this genus with the purpose of discovering novel phylogenetic characters and clarifying species relationships. I briefly describe the adult carapace and trace some of the major morphological changes that occur over the last several instars. I focus particular attention on the arrangement of fossae in the reticulate mesh; these features have been shown in other ostracodes to correspond to underlying epidermal cells. I describe the development of fossae in the region posterior to the adductor muscle scars, and hypothesize a sequence of specific cell divisions to account for the addition of fossae over ontogeny. Phylogenetic characters were derived from many different types of characters, including aspects of carapace shape, the presence and location of pores, characteristics of specific ridges and spines, and the relative position of homologous fossae in the reticulum. A parsimony analysis of 42 characters and 40 operational taxonomic units (36 ingroup and four outgroup) resulted in a set of optimal trees whose strict consensus is relatively well resolved, well supported, and generally consistent with the order in which taxa appear in the fossil record. The monophyly of Poseidonamicus is supported, as is the monophyly of all deep-sea members of this genus. Within the clade of deep-sea Poseidonamicus, several subgroups are recovered with varying levels of character support. In addition to providing a general framework for understanding morphological evolution in this genus, the results of this phylogenetic analysis have two specific implications for the evolution of sightedness in this genus. First, because Poseidonamicus ocularis is nested deeply within a clade of entirely deep-sea species, its putatively ocular features are probably not related to vision. Second, there has likely been just a single transition from sighted to blind in Poseidonamicus, coincident with its colonization of the deep sea. No support is found for the recent suggestion that sighted shallow-water dwelling Poseidonamicus species may have evolved from blind deep-sea ancestors, although data from additional taxa will be necessary to test this hypothesis more fully.

Supaia anomala White dominate floodplain deposits of a narrow stratigraphic interval of the middle Abo Formation, Lower Permian of central New Mexico. The plant fossils occur in thinly bedded units up to two meters thick, consisting of coarse siltstone to very fine sandstone with clay partings. Bedding is primarily tabular, thin, and bears rare ripple marks and trough cross beds. Bedding surfaces display mud cracks, raindrop imprints, horizontal and vertical burrows of invertebrates, and footprints of terrestrial vertebrates. These features indicate intermittent and generally unchannelized stream flow, with repeated exposure to air. Channels appear to have cannibalized one another on a slowly subsiding coastal plain. Conifers are dominant at three collecting sites and at three others Supaia dominates. Although each of these genera occurs in assemblages dominated by the other, there are no truly co-dominant assemblages. This pattern suggests alternative explanations. Landscapes could have consisted of a small-scale vegetational patchwork dominated almost monospecifically in any one patch, meaning that these plants could have coexisted across the landscape. On the other hand, conifer and supaioid dominance could have been temporally distinct, occurring during different episodes of sedimentation; although in the field there are no noticeable sedimentological differences between conifer-dominated and Supaia-dominated channel deposits, they may represent slightly different climatic regimes. The considerable morphological differences between conifers and Supaia suggest that the floristic patterns are not a taphonomic effect of the loss of a significant part of the original biodiversity. In general, the climate under which this vegetation developed appears to have been relatively warm and arid, based on the geology (pervasive red color [oxidation], calcrete in paleosols, and abundant mud cracks evidencing ephemeral flow in streams) and biology (low floristic diversity, xeromorphic plant physiognomies).

While estimating the statistical properties of small-scale topography is of particular interest for geologic analysis of Cassini radar data, there is no analytic description of radar scattering over a wide range of incidence angles and roughness. This paper presents an empirical function that links the rms slope at the horizontal scale of the wavelength and HH- or VV-polarization radar echoes. The model is based on comparison of 24-cm wavelength AIRSAR data for lava flows in Hawai'i, at incidence angles of 25 degrees to 55 degrees , with topographic profiles at 25-cm posting. Comparison of model predictions to the range of observed Titan echoes suggests that the radar return is often dominated by a component arising from subsurface scattering.

Previous studies had shown that PCO errors are absorbed mainly by parameters representing satellite clock and the radial components of site position. On the basis of the assumption that the radial errors are equal, PCO errors will therefore introduce an error in network scale. However, PCO errors also introduce distortions, or apparent deformations, within the network, primarily in the radial (vertical) component of site position that cannot be corrected via a Helmert transformation. Using numerical simulations to quantify the effects of PCO errors, we found that these PCO errors lead to a vertical network distortion of 6-12 mm per meter of PCO error. The network distortion depends on the minimum elevation angle used in the analysis of the GPS phase observables, becoming larger as the minimum elevation angle increases. The steady evolution of the GPS constellation as new satellites are launched, age, and are decommissioned, leads to the effects of PCO errors varying with time that introduce an apparent global-scale rate change. We demonstrate here that current estimates for PCO errors result in a geographically variable error in the vertical rate at the 1-2 mm yr (super -1) level, which will impact high-precision crustal deformation studies.

However, species may change in key traits as they invade a new region, making prediction difficult. For marine invertebrate invaders there have been too few comparative studies to determine whether change in key traits is the exception or the rule. Here we examined populations of the intertidal barnacle Chthamalus proteus in three locations in its native range in the Caribbean and Atlantic, and in the Hawaiian Islands, where it has recently invaded, as a model system for such comparative studies. We measured body size, fecundity, population density and vertical distribution, compared habitat use and investigated aspects of the barnacle's ecological role in Curacao, Panama and Brazil and the main Hawaiian Islands. In terms of these measures, the barnacle has undergone little change in its invasion of Hawaii. Thus, if this barnacle had been studied in its native range, predictions about its spread in Hawaii could have been made. As little was known about this barnacle in either its native range or Hawaii, we also carried out studies of its larval life history, fecundity, growth, and mortality. Based on this work, we predict that this barnacle will continue to spread, aided by vessel traffic, throughout the Hawaiian Islands and elsewhere in the Pacific.

They are prime factors influencing species distribution patterns, diversity and habitat associations in a range of biomes, and limit primary productivity in many natural ecosystems, as well as in forestry and agricultural systems (Hawkins et al. 2003, Kozlowski & Pallardy 1997, Lieth 1975). Projections of drying trends, and increased frequency and intensity of drought events with climate and land-use changes (Hulme & Viner 1998, IPCC 2001) have fuelled an increased interest in the role of drought in determining the structure and function of natural and managed forest systems (Allen & Breshears 1998, Miles et al. 2004). Such projections accentuate the need to assess, understand and predict plant reactions to drought, as well as soil moisture variation at different scales.

Carolinensis) AN - 20690503; 8195431 AB - Vocal admixture often occurs where differentiated populations or species of birds meet. This may entail song sympatry, bilingually singing birds, and songs with intermediate or atypical characteristics. Different levels of vocal admixture at the range interface between Black-capped Chickadees (Poecile atricapillus) and Carolina Chickadees (P. carolinensis) have been interpreted as indicating that hybridization is frequent at some locations but not others. However, song ontogeny in these birds has a strong nongenetic component, so that inferences regarding hybridization based on vocal admixture require confirmation. We used diagnostic genetic markers and quantitative analyses of song to characterize population samples along two transects of the chickadee contact zone in the Appalachian Mountains. More than 50% of individuals at the range interface were of hybrid ancestry, yet only 20% were observed to be bilingual or to sing atypical songs. Principal component analysis revealed minimal song intermediacy. This result contrasts with an earlier analysis of the hybrid zone in Missouri that found considerable song intermediacy. Re-analysis of the Missouri data confirmed this difference. Correlation between an individual's genetic composition and its song type was weak in Appalachian hybrid populations, and genetic introgression in both forms extended far beyond the limits of vocal admixture. Therefore, song is not a reliable indicator of levels of hybridization or genetic introgression at this contact zone. Varying ecological factors may play a role in producing variable levels of song admixture in different regions of the range interface.Una Evaluacion de la Mixtura de Cantos como Indicador de Hibridacion en Poecile atricapillus y P. carolinensisOriginal Abstract: La mixtura vocal ocurre usualmente donde poblaciones diferenciadas o especies de aves se encuentran. Esto puede implicar simpatria en los cantos, aves bilinguees en sus cantos y cantos con caracteristicas intermedias o atipicas. Los diferentes niveles de mixtura vocal en la interfase de los rangos de Poecile atricapillus y P. carolinensis han sido interpretados como indicadores de que la hibridacion es frecuente en algunas localidades, pero no en otras. Sin embargo, la ontogenia del canto en estas aves presenta un fuerte componente no genetico, por lo que las inferencias sobre la hibridacion basadas en la mixtura de vocalizaciones requieren ser confirmadas. Usamos marcadores geneticos diagnosticos y analisis cuantitativos de los cantos para caracterizar las muestras poblacionales a lo largo de dos transectas de la zona de contacto entre las especies de estudio en las Montanas Apalaches. Mas del 50% de los individuos de la interfase de los rangos fueron de origen hibrido, aunque se observo que solo el 20% de los individuos fueron bilinguees o cantaron canciones atipicas. Analisis de componentes principales revelaron que los cantos intermedios fueron minimos. Estos resultados contrastan con un analisis anterior de la zona hibrida de Missouri que encontro niveles considerables de cantos intermedios. El reanalisis de los datos de Missouri confirma esta diferencia. La correlacion entre la composicion genetica de los individuos y su tipo de canto fue debil en las poblaciones hibridas de los Apalaches, y la introgresion genetica en ambas formas se extendio considerablemente mas alla de los limites de la mixtura de voces. Por lo tanto, los cantos no son un indicador confiable de los niveles de hibridacion o de introgresion genetica en esta zona de contacto. Los factores ecologicos cambiantes podrian jugar un papel en producir niveles variables de mixtura de cantos en diferentes regiones de la interfase de los rangos.

To understand the origins of this impressive distribution, we used five mitochondrial gene sequences to reconstruct the historical biogeography of the genus. The resulting phylogeny indicates a rapid initial spread of the genus to occupy most of its contemporary continental range at least as far south as lower Mesoamerica, plus Hawaii and the Greater Antilles. The North American M. townsendi appears to be the sister taxon of the rest of Myadestes. Myadestes obscurus of Hawaii is more closely allied to Mesoamerican lineages than to M. townsendi. The strongly supported sister relationship of the two West Indian taxa, M. elisabeth and M. genibarbis, indicates a single colonization of the West Indies. A more recent node links the Andean M. ralloides to the Mesoamerican M. melanops and M. coloratus. A standard molecular clock calibration of 2% sequence divergence per million years for avian mitochondrial DNA suggests that the initial diversification of Myadestes occurred near the end of the Miocene (between 5 and 7.5 mya). Cooler temperatures and lower sea levels at that time would have increased the extent of montane forests and reduced overwater dispersal distances, possibly favoring range expansion and colonization of the West Indies. The split between South American and southern Mesoamerican lineages dates to similar to 3 mya, which suggests that Myadestes expanded its range to South America soon after the Pliocene rise of the Isthmus of Panama. Despite the demonstrated capacity of Myadestes for long-distance dispersal, several species of Myadestes are highly differentiated geographically. Phylogeographic structure was greatest in the West Indian M. genibarbis, which occurs on several islands in the Greater Antilles and Lesser Antilles, and in the Andean M. ralloides. The phylogeographic differentiation within M. ralloides was not anticipated by previous taxonomic treatments and provides a further example of the importance of the Andes in the diversification of Neotropical birds. Overall, the historical biogeography of Myadestes suggests that range expansion and long-distance dispersal are transient population phases followed by persistent phases of population differentiation and limited dispersal.Biogeografia Historica de los Zorzales del Genero MyadestesOriginal Abstract: Los zorzales del genero Myadestes son aves de bosques montanos que se encuentran ampliamente distribuidas en el Nuevo Mundo, desde Alaska hasta el norte de Bolivia, incluyendo a Hawai y a las Antillas. Con el objetivo de entender el origen de esta impresionante distribucion, utilizamos secuencias de cinco genes mitocondriales para reconstruir la biogeografia historica de Myadestes. La filogenia resultante indica una expansion inicial rapida del genero para ocupar la mayor parte de su rango continental, al menos hasta la parte baja de Mesoamerica hacia el sur, ademas de Hawai y las Antillas Mayores. La especie norteamericana M. townsendi parece ser el taxon hermano del resto de los Myadestes. La especie M. obscurus de Hawai esta mas estrechamente emparentada con linajes mesoamericanos que con M. townsendi. La relacion de taxones hermanos entre las dos especies de las Antillas (M. elisabeth y M. genibarbis) esta fuertemente apoyada, lo que indica una colonizacion unica de estas islas. Un nodo mas reciente conecta a la especie andina M. ralloides con las especies mesoamericanas M. melanops y M. coloratus. Una calibracion estandar del reloj molecular de 2% de divergencia en secuencias por millon de anos para el ADN mitocondrial de las aves, sugiere que la diversificacion inicial de Myadestes sucedio cerca del final del Mioceno (entre 5 y 7.5 millones de anos antes del presente). Las temperaturas mas frias y los niveles mas bajos del oceano existentes durante ese periodo podrian haber incrementado la extension de los bosques montanos y reducido las distancias de dispersion sobre el agua, posiblemente favoreciendo la expansion del rango de Myadestes y su colonizacion de las Antillas. La separacion entre los linajes de America del Sur y del sur de America Central sucedio hace cerca de tres millones de anos, lo que sugiere que Myadestes expandio su rango hacia America del Sur poco despues del levantamiento pliocenico del Istmo de Panama. A pesar de la evidente habilidad de dispersion a grandes distancias que presenta Myadestes, varias especies del genero se encuentran altamente diferenciadas geograficamente. La estructura filogeografica fue mas marcada en la especie M. genibarbis, la cual se encuentra en varias de las Antillas Mayores y Menores, y en la especie andina M. ralloides. La diferenciacion filogeografica existente en M. ralloides no habia sido anticipada por tratamientos taxonomicos previos, y provee un nuevo ejemplo de la importancia de los Andes en la diversificacion de las aves neotropicales. En general, la biogeografia historica de Myadestes sugiere que la expansion de los rangos de distribucion y los eventos de dispersion a grandes distancias son fases transitorias, que estan seguidas por fases de diferenciacion poblacional y dispersion limitada.

As the wild becomes less so, more species are placed in captivity to improve their chances of long-term survival, while concurrently management (and medicine) for free-ranging wildlife has become increasingly important. A variety of disciplines, including veterinary medicine, is now recognized as key to wildlife conservation. Although veterinarians have been involved in conservation for decades, it is only recently that their role has become more appreciated in the larger conservation community. This realization of the contributions of veterinarians has occurred at a time when disease has been recognized as significantly impacting species' conservation both in situ and ex situ. Today, veterinarians work with captive and free-ranging animals to prevent andor treat diseases that threaten species' survival. Most of these diseases are associated with the increasing human footprint. In this paper, I present wildlife health in today's world and the zoo veterinarian's role in wildlife conservation.

The habitat of a particular community is embedded within a larger habitat or ecosystem with many species shared between the focal community and the larger system. Pen shells (Atrina rigida) are large bivalves that, once the mollusk dies, provide shelter for motile species and hard substrate for settling larval invertebrates and egg-laying fishes. In St. Joseph's Bay, Florida (29 degree 45'N, 85 degree 15'W), pen shells are the most abundant source of hard substrate, especially inside sea grass (Thalassia testudinum) beds, where they reach densities of 0.1-4.0 m super(-2). This study, which was conducted from May to August 2005, measured the overlap in species densities between dead pen shells and the surrounding sea grass communities at eight sites to determine the discreteness of the pen shell communities. Of the 70-epibenthic taxa recorded, 66% were found on the pen shells but not in the surrounding sea grass habitat. Community structure, which varied among shells within sites and among the eight sites, could be related to sea grass characteristics such as blade density and length either directly (e.g., inhabitants of pen shells directly benefit from the surrounding sea grass) or indirectly (e.g., pen shells and sea grass both benefit from similar factors such as current and nutrients). Pen shells were randomly distributed at several spatial scales within the 15 x 15 m sites as were many motile species. Two exceptions were the shrimp, Palaemon floridanus and the amphipod, Dulichella appendiculata, whose distributions were clumped. Most of the sessile species had clumped distributions, tending to be very abundant when they were present. These pen shell communities provide an opportunity for experimental studies of factors affecting species diversity on small, discrete, naturally occurring habitats.

Samples were collected from November 1994 to October 2004. We identified 241 infected birds (34.0%). Base-on-sequence data for the cytochrome b gene from 221 positive samples, 34 distinct lineages of Plasmodium, and 41 of Haemoproteus were detected. Parasite diversity was highest in Myanmar followed by India and South Korea. Parasite prevalence differed among regions but not among host families. There were four lineages of Plasmodium and one of Haemoproteus shared between Myanmar and India and only one lineage of Plasmodium shared between Myanmar and South Korea. No lineages were shared between India and South Korea, although an equal number of distinct lineages were recovered from each region. Migratory birds in South Korea and India originate from two different migratory flyways; therefore cross-transmission of parasite lineages may be less likely. India and Myanmar shared more host species and habitat types compared to South Korea. Comparison between low-elevation habitat in India and Myanmar showed a difference in prevalence of haematozoans.

The present study uses the rich fossil record of the ostracode genus Poseidonamicus to reconstruct in great detail the evolutionary history of a set of landmark-based morphometric characters. This reconstruction included two kinds of evolutionary inferences: ancestor-descendant transitions among populations repeatedly sampled at the same location and divergence between lineages measured as independent contrasts on a phylogeny. This reconstructed history was then used to test if evolutionary changes were concentrated in directions (traits or combinations of traits) with high phenotypic variance. Two different statistics of association between evolution and variation tested the null hypothesis that evolutionary changes occur in random directions with respect to trait variability. The first of these measured the similarity between the directions of evolutionary change and the axis of maximum variance, and the second measured the degree to which evolutionary changes were concentrated in directions of high phenotypic variation. Randomization tests indicated that both kinds of evolutionary inferences (ancestor-descendant and phylogenetic contrasts) occurred preferentially in directions of high phenotypic variance (and close to the axis of maximal variation), suggesting that within-population variation can structure long-term divergence. This effect decayed after a few million years, but at least for one metric, never disappeared completely. These results are consistent with Schluter's genetic constraints model in which evolutionary trajectories on adaptive landscapes are deflected by variation within and covariation among traits.

Plant chitinases are involved in a wide variety of processes; in particular, their expression has been found to be enhanced in symbiotic and pathogenic plant-microbe interactions. During this work we have cloned and characterized a gene encoding a class III chitinase from actinorhizal nodules of Casuarina glauca (cgchi3). CGCHI3 was found to be encoded by a single gene that was specifically activated in nodules as compared with uninoculated control roots and leaves. The expression of this gene was further enhanced in nodules after salicylic acid treatment and completely repressed after wounding. In situ hybridisation analysis revealed that cgchi3 is an early nodulin gene, being expressed in the meristem and in the uninfected cortical cells of young nodules. Based on the obtained results we suggest that this gene is involved in nodule development. This is the first report on a class III chitinase coding gene that is specifically activated during actinorhizal symbiosis.

We aimed to establish how many species occurred among specimens from 61 sites throughout Australia, scored for 32 putative allozyme loci. We compared the number of species predicted from tree-based clustering of operational taxonomic units (OTUs) with that from a novel model-based Bayesian clustering approach for individual genotypes. We rejected the hypothesis of conspecificity of OTUs if they differed by at least 20% fixed differences and 0.300 Nei's standard genetic distance D. According to these criteria, 18-25 species occur, making this the most species-rich anopheline complex known to date. A conservative estimate from the Bayesian analysis was 15-20 species. There was large overlap in the assignment of individuals to clusters inferred from the Bayesian and tree-based analyses. The genetic clustering of northern and southern distributed species and an apparent cline in alleles of the enzyme glucose phosphate isomerase suggest that a latitude-dependent factor, such as temperature, may have played a role in speciation and the subsequent distribution of species. Ecological niche modelling of clusters predicted that none occur in New Guinea, emphasizing that additional, as yet unsampled, species may occur.

Location The Western Ghats is a chain of mountains about 1600 km in length, running parallel to the western coast of the Indian Peninsula from above 8 degree N to almost 21 degree N latitude. Methods We used data from 60 small plot inventories concentrated in three regions: the southernmost part of the Western Ghats (SWG) (8 degree 24' to 9 degree 37' N), the Nilgiri Hills (11 degree 12' to 11 degree 14' N), and the central Western Ghats (CWG) (12 degree 32' to 14 degree 51' N). We used Sorensen's index (SI) to estimate the similarity in species composition between two plots and regressed SI against the logarithm of the distance between plots to assess beta diversity. A bootstrapping procedure provided confidence intervals for regression coefficients. To test for the effects of climate, we regressed seasonality differences between plots against SI for low-elevation (< 800 m) plots along the north-south axis, and all plots in the SWG. We assessed the impact of the rainfall gradient in the Kogar region. Results Among all three regions, beta diversity was highest along the latitudinal axis, and along the rainfall gradient in the Kogar region. Differences in seasonality between sites were strongly related to beta diversity along the north-south seasonality gradient and within the SWG. Within the three regions, beta diversity was highest in the region with the strongest rainfall gradient and lowest for the topographically heterogeneous SWG. Beta diversity did not differ between forest strata and dispersal modes. Main conclusions We conclude that climate, particularly seasonality, is probably the primary driver of beta diversity among rain forest trees of the Western Ghats complex.

This management objective can prove difficult to accomplish in some NHP given increasing white-tailed deer (Odocoileus virginianus) densities. Our goal was to quantify the impact of white-tailed deer foraging on agricultural landscapes in forested NHPs in Maryland, USA. We monitored 12 and 13 corn (Zea mays) fields at 3 NHP during the 2003 and 2004, respectively. Each field had 3 5 × 5-m fenced and unfenced plots along the edge and a similar set within the interior of the field. Within each plot we examined the number of stalks with corn, corn ear quality, and field weight prior to harvest. Fenced plots had higher weights of corn, more stalks with corn ears, and higher quality corn than unfenced plots. Estimates of silage yield based on crop weights indicate deer reduced silage yield in individual fields by 5– 43� during the study period. Crop loss differed between years and fields, with plots in the Chesapeake and Ohio Canal NHP sustaining the highest crop weight loss (28� ). Eventual crop loss was correlated with proportion of corn plants browsed within 2 weeks of emergence. Some variability in loss between fields was due to landscape metrics, as fields surrounded by more forest experienced the highest loss. Our results indicate the NHP agriculture fields we studied receive significant deer damage to corn crops and may not be able to maintain mandated management without regulating deer numbers.

In this study, we evaluated the role of distinct hydrologic regimes in determining the spatial genetic structure of the seed bank of the wetland plant Hibiscus moscheutos. We analyzed seeds in surface soil samples collected in the autumn and the following spring by determining their allozyme genotypes and estimated the pattern in seed movements during flooding. We selected study sites in nontidal and tidal wetlands with different flooding regimes. One nontidal site had no flooding, while the second nontidal site was inundated for most of the year. One tidal wetland site flooded with almost every tide, and a second tidal site was inundated at moderate frequency. Genetic makeup of the seed bank at the nonflooded site changed little between seasons. Secondary seed dispersal altered absolute allele frequencies at the other three sites, with the greatest change occurring at the two tidally influenced sites. This study demonstrates that secondary hydrochory influences the genetic composition of the seed bank and that hydrologic conditions play an important role in determining the local patterns in seed movements.

We compared the bird diversity and community structure in organic cacao farms and nearby forest fragments throughout mainland Bocas del Toro, Panama. We used this dataset to ask the following questions: (1) How do bird communities using cacao habitat compare to communities of nearby forest fragments? (2) To what extent do Northern migratory birds use shaded cacao farms, and do communities of resident birds shift their abundances in cacao farms seasonally? (3) Do small scale changes in shade management of cacao farms affect bird diversity? Using fixed radius point counts and additional observations, we recorded 234 landbird species, with 102 species that were observed in both cacao and forest fragments, 86 species that were only observed in cacao farms, and 46 species that were restricted to forest fragments. Cacao farms were rich in canopy and edge species such as tanagers, flycatchers and migratory warblers, but understory insectivores were nearly absent from cacao farms. We observed 27 migratory species, with 18 species in cacao farms only, two species in forest only, and seven species that occurred in both habitats. In cacao farms, the diversity of birds was significantly greater where there was less intensive management of the canopy shade trees. Shade tree species richness was most important for explaining variance in bird diversity. Our study shows that shaded cacao farms in western Panama provide habitat for a wide variety of resident and migratory bird species. Considering current land use trends in the region, we suggest that action must be taken to prevent conversion away from shaded cacao farms to land uses with lower biodiversity conservation value.

The ratio of fire detection densities (detections per square kilometer) inside reserves to their contiguous buffer areas provided an index of reserve effectiveness. Fire detection density was significantly lower inside reserves than in paired, contiguous buffer areas but varied by five orders of magnitude among reserves. The buffer: reserve detection ratio varied by up to four orders of magnitude among reserves within a single country, and median values varied by three orders of magnitude among countries. Reserves tended to be least effective at reducing fire frequency in many poorer countries and in countries beset by corruption. Countries with the most successful reserves include Costa Rica, Jamaica, Malaysia, and Taiwan and the Indonesian island of Java. Countries with the most problematic reserves include Cambodia, Guatemala, Paraguay, and Sierra Leone and the Indonesian portion of Borneo. We provide fire detection density for 3964 tropical and subtropical reserves and their buffer areas in the hope that these data will expedite further analyses that might lead to improved management of tropical reserves.

Historical studies of climate and vegetation are closely associated with crop plant evolution because they can reveal the ecological contexts of plant domestication together with the antiquity and effects of agricultural practices on the environment. In this article, we present paleoecological evidence from three lakes and a swamp located in the Central Balsas watershed of tropical southwestern Mexico that date from 14,000 B.P. to the modern era. [Dates expressed in B.P. years are radiocarbon ages. Calibrated (calendar) ages, expressed as cal B.P., are provided for dates in the text.] Previous molecular studies suggest that maize (Zea mays L.) and other important crops such as squashes (Cucurbita spp.) were domesticated in the region. Our combined pollen, phytolith, charcoal, and sedimentary studies indicate that during the late glacial period (14,000-10,000 B.P.), lake beds were dry, the climate was cooler and drier, and open vegetational communities were more widespread than after the Pleistocene ended. Zea was a continuous part of the vegetation since at least the terminal Pleistocene. During the Holocene, lakes became important foci of human activity, and cultural interference with a species-diverse tropical forest is indicated. Maize and squash were grown at lake edges starting between 10,000 and 5,000 B.P., most likely sometime during the first half of that period. Significant episodes of climatic drying evidenced between 1,800 B.P. and 900 B.P. appear to be coeval with those documented in the Classic Maya region and elsewhere, showing widespread instability in the late Holocene climate.

However, so far quantitative, long-term, and large-scale assessments of their impact on these ecosystems are rare, because the available assessment methods were laborious andor destructive. We describe a rapid, nondestructive, and inexpensive method to estimate the long-term harvest of Atta colombica colonies. Workers of A. colombica dump the colony refuse (exhausted fungal substrate) outside the nest. A single trail connects the refuse pile and the nest. In contrast to the foraging activity, the refuse deposition rate (the number of deposited refuse particles per minute) is diurnally constant and varies little on subsequent days. The number of refuse particles deposited per day was tightly correlated with the number of harvested fragments in nests of differing sizes (R super(2)= 0.77, P < 0.0001). Therefore, the daily harvest of a particular colony can be calculated from short-term counts (5 min) of the refuse deposition rate at any time of the day. Combining these data with information on average fragment size (weight andor area) allows the calculation of the total daily amount of biomass andor foliage area harvested by the colony. This new method facilitates quantifying A. colombica herbivory on scales of populations and ecosystems, or over long-term scales.

Despite its ecological importance, relatively little is known about the diversity and composition of this important component of intertidal biodiversity. In this study, we quantified species composition, abundance and distribution of ostracodes, an important group of phytal meiofauna, at two different intertidal areas in southern California. In total, we recovered 22 ostracode species from three different orders (16 podocopids, five myodocopids and one platycopid), nearly a quarter of which could not be assigned to existing taxa. The abundance of ostracodes differed significantly among algal types, with structurally complex algae bearing many more ostracodes per gram of algae than simple forms (blade-like algae and the surfgrass Phyllospadix). Although most ostracode species were recovered from multiple kinds of algae, different algae harbored distinct assemblages that could be discriminated statistically on the basis of relative abundances of ostracode species. This segregation of the ostracode fauna according to algal species is evident even over very short spatial scales (<1 m). Finally, ostracode samples from turf-forming algae were more species rich than samples from other kinds of macroalgae. Since turf-forming algae are easily damaged by human trampling, this component of ostracode biodiversity may be particularly vulnerable to anthropogenic impacts on the intertidal habitat.

A total of 17 soil and 116 feather samples were collected from five avian species across multiple habitat types within one Neotropical and one temperate locality. Hypotheses regarding patterns of microbial composition relative to acquisition and dispersal of plumage bacteria in the ecosystem were tested by comparing microbial communities within and between soil and plumage. Samples from the plumage of American Redstarts (Setophaga ruticilla) were collected across both habitat types and geographic scales for intraspecific comparisons. The microbial diversity in avian plumage was moderately diverse and was dominated by Pseudomonas species. Despite a highly significant individual bird effect on microbial composition of the plumage, we detected significant biogeographic and type of habitat effects. Pseudomonas species were more abundant on the temperate site when all avian species were included in the analysis, and Bacillus subtilis and Xanthomonas groups were more abundant on the Neotropical site for redstarts alone. However, 16S rDNA sequence libraries were not significantly different between Jamaican and Maryland redstarts. Biogeographic and habitat effects were significant and more pronounced for soil samples indicating lower dispersal of soil microbiota. We detected a significant difference between soil and plumage microbial communities suggesting that soil plays a small role in plumage bacterial acquisition. Our results suggest bacterial communities on the plumage of birds are dynamic and may change at different stages in a bird's annual cycle.

In this study, the consumption and herbivory rates for the entire leaf-cutting ant (Atta colombica, Formicidae) population in an old secondary forest on Barro Colorado Island (BCI) in Panama were determined over 15 mo (on average 49 colonies). The number of harvested leaf fragments was calculated from monthly refuse deposition rates of the colonies and the regression between refuse deposition and harvesting rates. The inclusion of fragment characteristics (proportion of leaf fragments in the harvest, average fragment weight, and area) allowed us to calculate consumption and herbivory rates at colony, population, and ecosystem levels. The A. colombica population harvested 13.2 tons of biomassyr and 13.1 ha of leaf areayr, and deposited 9.4 tons of refuse materialyr. Rates varied considerably among colonies. At the ecosystem level, i.e., per forest area, herbivory rates were 132 kg biomasshayr and 1310 m super(2) foliagehayr. For the area on BCI where A. colombica occurs (100 ha), this is equivalent to 2.1 percent of the foliage area in the forest or 1.7 percent of the annual leaf-area production. This value is considerably lower than previously published estimates of leaf-cutting ant herbivory rates in tropical forests.

However, recent paleoecological reconstructions based on tooth wear, carbon isotopes, and functional morphology indicate that grasses played a minor role in Late Miocene ecosystems of the eastern Mediterranean, which were more likely dry woodlands or forests. The scarcity of grass macrofossils and pollen in Miocene floras of Europe and Asia Minor has been used to support this interpretation. Based on the combined evidence, it has therefore been suggested that Late Miocene ungulate faunal change in the eastern Mediterranean signals increased aridity and landscape openness, but not necessarily the development of grass-dominated habitats. To shed new light on the Miocene evolution of eastern Mediterranean ecosystems, we used phytolith assemblages preserved in direct association with faunas as a proxy for paleovegetation structure (grassland vs. forest). We extracted phytoliths and other biogenic silica from sediment samples from well-known Early to Late Miocene (~20-7 Ma) faunal localities in Greece, Turkey, and Iran. In addition, a Middle Eocene sample from Turkey yielded phytoliths and served as a baseline comparison for vegetation inference. Phytolith analysis showed that the Middle Eocene assemblage consists of abundant grass phytoliths (grass silica short cells) interpreted as deriving from bambusoid grasses, as well as diverse forest indicator phytoliths from dicotyledonous angiosperms and palms, pointing to the presence of a woodland or forest with abundant bamboos. In contrast, the Miocene assemblages are dominated by diverse silica short cells typical of pooid open-habitat grasses. Forest indicator phytoliths are also present, but are rare in the Late Miocene (9-7 Ma) assemblages. Our analysis of the Miocene grass community composition is consistent with evidence from stable carbon isotopes from paleosols and ungulate tooth enamel, showing that C sub(4) grasses were rare in the Mediterranean throughout the Miocene. These data indicate that relatively open habitats had become common in Turkey and surrounding areas by at least the Early Miocene (~20 Ma), >7 million years before hipparionine horses reached Europe and arid conditions ensued, as judged by faunal data.

Diseases caused by introduced pathogens have had large impacts on species abundances, including the American chestnut, Hawaiian bird species and many amphibians. Changes in host population sizes can lead to marked shifts in community composition and ecosystem functioning. However, identifying the impacts of an introduced disease and distinguishing it from other forces that influence population dynamics (for example, climate) is challenging and requires abundance data that extend before and after the introduction. Here we use 26yr of Breeding Bird Survey (BBS) data to determine the impact of West Nile virus (WNV) on 20 potential avian hosts across North America. We demonstrate significant changes in population trajectories for seven species from four families that concur with a priori predictions and the spatio-temporal intensity of pathogen transmission. The American crow population declined by up to 45% since WNV arrival, and only two of the seven species with documented impact recovered to pre-WNV levels by 2005. Our findings demonstrate the potential impacts of an invasive species on a diverse faunal assemblage across broad geographical scales, and underscore the complexity of subsequent community response.

The entire sample consists of 455 bone fragments from 57 chimpanzee hunting episodes of 65 prey individuals at Ngogo, Kibale National Park, Uganda. It has low taxonomic diversity, consisting overwhelmingly of primates, especially red colobus monkeys. The age distribution of the prey remains is skewed towards pre-adults. Cranial bones are the dominant element, followed by long bones. Axial postcranial elements have low survivorship, with a complete absence of pre-caudal vertebrae. Bone is damaged in distinct ways, such as: destruction of long bone ends, typically with intact but chewed shafts; fragmentation and compression cracking of crania; and preservation of only the iliac blades of the innominates. Tooth marks are present but uncommon (4.4% of total NISP). These analyses enable us to: 1) describe and characterize consistent patterns of bone damage inflicted by chimpanzees across a much larger prey sample than has been previously studied; 2) make a preliminary comparison of the generalized chimpanzee taphonomic signature to that of leopard and eagle consumption of primates, as well as modern human consumption of small mammals; and 3) assess the utility of such samples for recognition of early hominin small mammal carnivory. We present a model that may be useful for detecting a pre-technological hominin carnivory and suggest some fossil locales at which close inspection of cercopithecoid remains for the above patterns might reveal traces of hominin hunting, though we caution that a pre-technological hominin hunted 'assemblage' is not likely to be archaeologically visible.

Several carbon cycle attributes were measured in eight created Spartina alterniflora Loisel salt marshes that ranged from one to 28 years, each paired with a nearby mature natural reference marsh. The attributes measured included gross primary production, respiration, net ecosystem exchange, potential microbial respiration (CH sub(4) and CO sub(2)), and aboveground biomass. In situ exchange rates of CO sub(2) and plant biomass in created marshes met or exceeded those of reference marshes in three to four years. There was some evidence that ecosystem gas exchange in created marshes developed slightly faster than aboveground biomass production. Soil carbon mineralization per gram carbon was generally higher in the created marshes than reference marshes, suggesting higher carbon quality and/or nutrient availability in the created marshes. However, carbon mineralization rates per gram soil were relatively low in the created marshes due to lower soil organic matter content. With proper construction, we suggest most major carbon fluxes can be established in created salt marshes in less than five years.

Results show that mean zooid length, zooid width and zooid area vary significantly between clonal replicates of C. exfragminis kept under different controlled temperature conditions. Significantly larger zooids are produced during times of lowered water temperature that are comparable with the temperatures that occur during seasonal upwelling along the Pacific coast of Panama where the animal lives in abundance. Interpolation of data suggests that a drop of 1 degree C causes a 5% increase in zooid size, and that almost all variation in zooid size in natural populations can be explained by temperature. Results are discussed in context of the potential use of zooid size variation in cupuladriid bryozoans to measure the strength of seasonal upwelling in ancient seas by analysing zooid size changes in fossil colonies. The technique of cloning cupuladriid colonies by fragmentation is also discussed with reference to its benefits in experimental studies where genotypes need to be controlled or replicated.

In September 2004, our research site on a fire-regenerated scrub-oak ecosystem in central Florida was struck by Hurricane Frances with sustained winds of 113 km h super(-1) and wind gusts as high as 152 km h super(-1). We quantified the hurricane damage on this ecosystem resulting from defoliation: we measured net ecosystem CO sub(2) exchange, the damage and recovery of leaf area, and determined whether growth in elevated carbon dioxide concentration in the atmosphere (C sub(a)) altered this disturbance. The hurricane decreased leaf area index (LAI) by 21%, which was equal to 60% of seasonal variation in canopy growth during the previous 3 years, but stem damage was negligible. The reduction in LAI led to a 22% decline in gross primary production (GPP) and a 25% decline in ecosystem respiration (R sub(e)). The compensatory declines in GPP and R sub(e) resulted in no significant change in net ecosystem production (NEP). Refoliation began within a month after the hurricane, although this period was out of phase with the regular foliation period, and recovered 20% of the defoliation loss within 2.5 months. Full recovery of LAI, ecosystem CO sub(2) assimilation, and ecosystem respiration did not occur until the next growing season. Plants exposed to elevated C sub(a) did not sustain greater damage, nor did they recover faster than plants grown under ambient C sub(a). Thus, our results indicate that hurricanes capable of causing significant defoliation with negligible damage to stems have negligible effects on NEP under current or future CO sub(2)-enriched environment.

The external sexual characters typically used to sex caridean shrimps are lacking in Synalpheus. We used SEM sexing technique to determine the sexual composition of helpers in colonies of Synalpheus regalis, S. rathbunae, S. chacei, S. rathbunae A (see Morrison et al. Mol Phylogen Evol 30:563-568, 2004), and S. filidigitus. Colonies consisted of both sexes and sex ratios of helpers generally conformed to 50:50 female to male. Females were characterized by gonopores with U-shaped slits on the coxae of the third pereopods (first walking legs) while males had oval gonopore openings on the coxae of the fifth pereopods (third or last walking legs). In S. chacei, S. filidigitus, and S. rathbunae A, a few helpers were found that had both male and female gonopores (intersexes). All three reproductive females (queens) of S. filidigitus examined were intersexes. Sexing of helpers allowed us to test some hypotheses about sexual differences in helper morphology that might indicate task specialization (division of labor). Male helpers were not different from female ones in body size (except in S. regalis: males somewhat larger) and in fighting chela size. The lack of sexual dimorphism in these characters suggests no male-female specialization in colony tasks such as defense. The presence of male and female helpers similar in size suggests that the sexual system of these eusocial species is gonochoristic, although protandry of some sort in S. filidigitus can not be ruled out. The intersexuality observed in a few individuals may be due to developmental anomalies, protandry, or even simultaneous hermaphroditism. Finally, the sexing technique allowed us to establish that new colonizers of unoccupied sponges in S. rathbunae are a single male and female of helper size.

The shelf is divided into two large semi-open areas, namely the non-upwelling Gulf of Chiriqui and the upwelling Gulf of Panama. Four research cruises sampled the water column in cross-shelf transects during wet and dry seasons at each region. Hydrological measures varied spatially between regions and also varied temporally on a seasonal basis. Low concentrations of NO sub(3) super(-) (0.5mg m super(-) super(3)) typically developed close to the usually shallow thermocline during non-upwelling conditions. We found no evidence of significant nutrient input from freshwater runoff. The position of the thermocline is considered to be the main source of nutrients to the euphotic zone in both regions.

These materials display a number of ceratosaur, abelisauroid, and abelisaurid synapomorphies, supporting the phylogenetic placement of Majungasaurus based previously on cranial anatomy. As in Ceratosaurus and Carnotaurus, the scapular blade is relatively wide and has a pronounced dorsal lip over the glenoid. The humerus is short and bears a globular head, but is more slender than in Carnotaurus. The ilium has a preacetabular hook, a strong supraacetabular crest, a notched posterior margin, and peg-and-socket articulations with both the pubis and ischium. Hind limb elements are proportionally stocky, as in some other abelisaurids. The femur lacks a trochanteric shelf, the tibia has a greatly enlarged cnemial crest, and the fibula bears a deep, posteriorly facing medial fossa. The abelisaurid astragalocalcaneum is described here in detail for the first time, and is more similar to that of tetanurans than to those of coelophysoids. Taken together, these materials illustrate that the appendicular skeleton of abelisaurids was specialized over the typical condition in basal theropods, particularly through the development of enlarged muscle attachment processes.

For almost a century, beginning in 1895, periodic expeditions conducted by French, Japanese, and Malagasy teams yielded fragmentary and isolated remains of a medium-sized theropod dinosaur from the Maevarano Formation. These materials were first assigned to Megalosaurus crenatissimus but later to Dryptosaurus crenatissimus, then Majungasaurus crenatissimus, and, most recently, Majungatholus atopus. The taxon was variously considered to pertain to Tyrannosauridae, "Megalosauridae," and Abelisauridae. Recent excavations undertaken by the Mahajanga Basin Project (1993 to present) have resulted in abundant and spectacular remains of this theropod. The new material allows us to establish Majungasaurus crenatissimus as the valid name for this theropod and to conclusively place it within Abelisauridae. M. crenatissimus is currently known from multiple specimens of various size (and presumably age) classes, which cumulatively represent the great majority of the skull and skeleton. Together, these finds establish Majungasaurus as among the best known of Gondwanan theropods. M. crenatissimus is one of several vertebrate taxa recovered from the Maevarano Formation that indicate close biogeographic ties linking Madagascar with the Indian subcontinent and South America. These data support the hypothesis of a high degree of cosmopolitanism among these landmasses, the result of a persistent subaerial connection between Indo-Madagascar to the east and South America to the west (possibly through Antarctica) until sometime late in the Late Cretaceous.

Reforestation may offer one means of mitigating these processes of degradation while sustaining resident human communities. However, a lack of information regarding tree species performance has been identified as an important limitation on the success and adoption of diversified reforestation strategies. We analyzed the initial growth of 22 native and 2 exotic tree species planted at three sites across a precipitation gradient in the Republic of Panama (1100-2200mmyear super(-) super(1)), and identify promising species for use in forest restoration, timber production and on-farm systems. At all sites, Acacia mangium, Diphysa robinoides, Gliricidia sepium, Guazuma ulmifolia and Ochroma pyramidale rapidly developed large, dense crowns and attained canopy closure after just 2 years. These species might be used in restoration efforts to rapidly stabilize soils and establish crown cover. As nitrogen-fixing legumes, D. robinoides and G. sepium may also have the potential to increase soil fertility. Several species valued for their timber performed well at all sites attaining high wood volume indices, these species included Tectona grandis, Pachira quinata and Tabebuia rosea. Albizia guachapele and Samanea saman were among the best performers at the driest site. The most promising species for use in silvopastoral systems varied among sites; A. guachapele, G. sepium, S. saman and G. ulmifolia performed best at the driest site, while G. sepium, G. ulmifolia and Spondias mombin were the top performers at the two wetter sites. It is hoped that the results of this trial will improve the success of reforestation efforts by allowing landholders to select species based upon both local site conditions and their specific reforestation objectives.

Efforts to evaluate proposed mechanisms have been hampered by a lack of comparative data on species' reactions to relevant axes of environmental variation. Here we show that differential drought sensitivity shapes plant distributions in tropical forests at both regional and local scales. Our analyses are based on experimental field assessments of drought sensitivity of 48 species of trees and shrubs, and on their local and regional distributions within a network of 122 inventory sites spanning a rainfall gradient across the Isthmus of Panama. Our results suggest that niche differentiation with respect to soil water availability is a direct determinant of both local-and regional-scale distributions of tropical trees. Changes in soil moisture availability caused by global climate change and forest fragmentation are therefore likely to alter tropical species distributions, community composition and diversity.

The transit and secondary eclipse occur at orbital phases of approximately 0 and approximately 0.5 respectively. A brightness T was calculated of 1205.1 + or - 9.3 K for the dayside of the planet from the depth of the secondary eclipse, and the planet has a minimum hemisphere-averaged brightness T 973 + or - 33 K occurring 6.7 + or - 0.4 hr after the transit, and a maximum hemisphere-averaged brightness T of 1212 + or - 11K occurring 2.3 + or - 0.8 hr before the onset of the secondary eclipse. The fact that the minimum and maximum T fluxes do not occur at phases of 0 and 0.5 respectively, indicate advection of the T pattern by atmospheric winds. The results overall argue for atmospheres that are very dark at visible wavelengths probably absorbing > or = 90% of the incident stellar flux with simultaneous transport of this energy to the nightside.

Although these assemblages are of interest from the evolutionary, biogeographic and conservation perspectives, their monophyly and phylogenetic relationships have yet to be rigorously evaluated. Here we present a molecular phylogeny (based on mitochondrial sequence data) of a putative flock of four thermal spring-dwelling springsnails that is distributed in many sites in Soldier Meadow and a single locality in Bog Hot Valley (northwestern Nevada). Our analyses support monophyly of this assemblage ('Soldier Meadow clade') and a close relationship with other regional species and suggest that the invasion of thermal habitats by these springsnails occurred independently of other such radiations within the genus. The divergence of the Soldier Meadow clade relative to its sister group is substantial (6.79-10.36% for COI, 10.35-15.88% for NDI), suggesting a split in the early Pliocene, based on the application of a COI clock for Pyrgulopsis. The splits within the Soldier Meadow clade into three main subunits also appear to be old events, based on their 5.78-8.54% COI divergence relative to each other. These findings are consistent with a long history of springsnail evolution in Soldier Meadow, which is intriguing given that this basin was flooded by Lake Lahontan during periods of the early and middle Pleistocene. We suggest that progenitors of the contemporary fauna survived in high elevation springs that may have been present in the basin during these pluvial periods and subsequently colonized contemporary habitats following the termination of the extreme Lake Lahontan highstands. We speculate that the broadly disjunct population (of P. militaris) in Bog Hot Valley, which is consistently nested within the Soldier Meadow clade in our phylogenetic analyses, is either a vicariant relict of a spring zone that may have once extended between these two areas; or was founded by a past 'jump' dispersal event from Soldier Meadow. Phylogeographic structure of springsnail populations in Soldier Meadow bears the strong stamp of geologically recent, allopatric diversification, perhaps reflecting the short time that basin floor habitats have been occupied. We describe a new species (P. varneri) for a series of recently discovered populations that are monophyletic, substantially divergent and morphologically distinctive.

This trend proves that the ancient Laurentian ice complex was composed of two large domes to the west and east of Hudson Bay, in accord with one of two classes of earlier reconstructions. Moreover, GIA models that reconcile the peak rates contribute approximately 25 to approximately 45% to the observed static gravity field, which represents an important boundary condition on the buoyancy of the continental tectosphere.

Middle-late Eocene floras in the central Rocky Mountains have been thought to reflect open savanna woodlands which, judging by the scarcity of grass fossils, consisted exclusively of small trees and shrubs. During the Oligocene, this vegetation type presumably spread, culminating with the development of conifer forests and steppe vegetation in the middle to late Miocene. In contrast, palynofloras from south-western Montana have pointed to the presence of grass-dominated habitats already in the early Oligocene. Thus, the role of grasses in Cenozoic Northern Rocky Mountain ecosystems has been incompletely known; in particular, the timing for the spread of steppe elements such as dry-adapted, open-habitat grasses was uncertain. A recently described record of plant silica (phytolith) assemblages helps shed light on vegetation change in the Northern Rocky Mountains. The majority of the Eocene and Oligocene phytolith assemblages are suggestive of closed forests with abundant dicotyledons, relatively rare palms, and little grass. Both typical closed-habitat grasses (e.g., bamboos) and open-habitat grasses were very uncommon. On the other hand, phytoliths of unknown grasses are frequent or dominant in a few cases, potentially supporting the suggestion that savanna woodlands existed in Montana as early as the late Eocene. However, because the autecology of these grasses is presently unclear, this hypothesis remains untested. In the early Miocene, open-habitat grasses expanded, resulting in grass-dominated savanna woodlands, similar to contemporaneous vegetation types in the Central Great Plains. The study also points to differences between interpretation of Cenozoic vegetation based on, respectively, phytoliths and other paleobotanical evidence. For example, previous work has failed to show the persistence of palms in the Northern Rocky Mountains through the middle Miocene. Conversely, the phytolith record does not clearly reflect the strong coniferous element evident in macrofossil and palynofloral data.

Vertebrate microfossil assemblages offer a promising means of quantifying paleoecology by offering large, diverse samples of parautochthonous taxa. In this study, four newly discovered microvertebrate sites from the Cloverly Formation are used to assess the composition and structure of the assemblage. Cloverly vertebrate specimens were identified to the lowest possible taxonomic level, and grouped into successively higher taxonomic categories. General anatomical and phylogenetic data were used to infer diet and habitat for each taxon, allowing a broad qualitative examination of the paleoecology of each site. Rarefaction of the Cloverly Formation bulk samples indicate that repeated sampling is not likely to produce significantly more taxa than the 31 taxa identified thus far. Principle coordinates analysis was applied to the taxon presence-absence data from the four Cloverly microsites, and non-metric multidimensional scaling was used to quantify taxon abundance differences. Specimen identifications from our sample of Cloverly microvertebrates greatly increased the known taxonomic diversity of the Cloverly Formation, especially with respect to aquatic forms. Preliminary paleoenvironmental and paleoecological reconstructions reveal both predominantly terrestrial and predominantly aquatic sites within the formation, although several aquatic and terrestrial taxa are ubiquitous. Continued study of such microvertebrate sites will allow a more comprehensive analysis of the Cloverly Formation's vertebrate fauna and their paleoenvironment.

It is composed of clastic rocks of moderately altered alkali basalt composition, enriched in some highly volatile elements. A coarse-grained lower unit lies under a finer-grained upper unit. Textural observations indicate that the lower strata were emplaced in an explosive event, and geochemical considerations favor an explosive volcanic origin over an impact origin. The lower unit likely represents accumulation of pyroclastic materials, whereas the upper unit may represent eolian reworking of the same pyroclastic materials.

Insects may actively render seed or fruit unpalatable or unusable to vertebrates as a strategy to maximize the amount of food available to themselves (Janzen 1977). Nevertheless, vertebrates sometimes do not differentiate between sound and infested seeds or fruits (Dixon et al. 1997, Weckerly et al. 1989), or even prefer insect-infested seeds and fruits to sound ones (Sallabanks & Courtney 1992, Semel & Andersen 1988, Steele et al. 1996, Valburg 1992). Possible reasons for vertebrates to prefer infested seeds include: (1) seeds with larvae having a higher nutritional value than sound ones, because larvae synthesize fat and/or proteins (Sallabanks & Courtney 1992, Valburg 1992) or other nutrients such as vitamins (Havera & Smith 1979, Semel & Andersen 1988, Steele et al. 1996); (2) seeds with larvae tasting better than sound seeds (Borowicz 1988); and (3) seeds with larvae may be more easily opened and consumed than sound seeds (Borowicz 1988).

By the 1960s it had undergone a sharp decline, and by the mid-1990s the local population consisted of 11 pairs in a single colony. Nesting was last documented in 2001. Declines had also become evident at several other breeding sites along the Hudson Bay coast of Manitoba and Ontario, as well as in the number of migrants detected on the Atlantic coast of Canada and the northern United States. Information on the biology of the Churchill population in 1993-2004 largely agreed with that gathered at La Perouse Bay, Manitoba, in the 1980s: reproductive success was good and new birds continued to join the colony; however, the number of breeding attempts by individuals was low and decreasing. As there is no evidence that the decline was related to local factors (e.g., altered habitats, climate change), it is probably attributable to mortality in the nonbreeding season, which leaves fewer birds available to return north. Whether causality can be fully resolved is problematic. Monitoring migrants can reveal population trends and studies on the breeding grounds can help frame hypotheses, but both approaches are time-consuming and provide only partial answers. In such cases, restoration of declining species may be best served by fostering habitat conservation throughout a species' range.

It should therefore be known as Buteogallus daggetti, new combination. Its habits were perhaps like those of a Savanna Hawk in that it was capable of taking much larger prey, given that the weight of B. daggetti may have exceeded that of the modern Secretarybird (Sagittarius serpentarius), and it may have occupied a similar niche. Any connection between its extinction and the disappearance of the North American mammalian megafauna is dubious at best.Original Abstract: Wetmoregyps daggetti, encontrado en el Pleistoceno en el sur de California y norte de Mexico, es practicamente identico en morfologia y en proporciones al gavilan pita venado Buteogallus meridionalis, aunque un 40% mas grande.

AN - 20351543; 7486140 AB - Theory shows that speciation in the presence of gene flow occurs only under narrow conditions. One of the most favourable scenarios for speciation with gene flow is established when a single trait is both under disruptive natural selection and used to cue assortative mating. Here, we demonstrate the potential for a single trait, colour pattern, to drive incipient speciation in the genus Hypoplectrus (Serranidae), coral reef fishes known for their striking colour polymorphism. We provide data demonstrating that sympatric Hypoplectrus colour morphs mate assortatively and are genetically distinct. Furthermore, we identify ecological conditions conducive to disruptive selection on colour pattern by presenting behavioural evidence of aggressive mimicry, whereby predatory Hypoplectrus colour morphs mimic the colour patterns of non-predatory reef fish species to increase their success approaching and attacking prey. We propose that colour-based assortative mating, combined with disruptive selection on colour pattern, is driving speciation in Hypoplectrus coral reef fishes.

Localized studies of fossil forests suggest intermixture of taxa (heterogeneity), while, in contrast, coal ball and palynological analyses imply the existence of pronounced ecological gradients. Here, we report the discovery of a spectacular fossil forest preserved over similar to 1000 ha on top of the Pennsylvanian (Desmoinesian) Herrin (No. 6) Coal of Illinois, United States. The forest was abruptly drowned when fault movement dropped a segment of coastal mire below sea level. In the largest study of its kind to date, forest composition is statistically analyzed within a well-constrained paleogeographic context. Findings resolve apparent conflicts in models of Pennsylvanian mire ecology by confirming the existence of forest heterogeneity at the local scale, while additionally demonstrating the emergence of ecological gradients at landscape scale.

Here, I show that the relationship is more complex than previously described, because the effect of one variable is dependent upon the value of the other. As a result, high-income nations exhibit the opposite response to disappearing forest cover than low-income nations. In an analysis of 103 countries, I found that high-income countries with low forest cover have the highest rates of afforestation, typically through the establishment of new plantations. In contrast, low-income countries with little forest are more likely to consume that remaining portion at a faster proportional rate than do low-income countries with more forest. Nations with large amounts of forest have approximately equal deforestation rates, regardless of national wealth. These results highlight for the first time that there is a strong interaction between forest cover and economic development that determines rates of forest change among nations.

Census data of a vascular epiphyte community from 0.4 ha of undisturbed lowland forest in Panama were used to infer future changes in community composition by deducing population growth from the current size class structure of populations. The study includes 11 387 individuals out of 45 species, ranging in abundance from 16 to 1568 individuals. There was a significant negative correlation between the size of a population and the steepness of the size distribution, indicating that more common species are likely to increase in abundance in the future, while rarer species apparently depend on immigration from other populations to allow local persistence.

We used the facultatively social sweat bee Megalopta genalis to test several benefits of group living. We surveyed natural nests modified for observation in the field weekly for 5 weeks in 2003. First, we demonstrate that social and solitary nesting are alternative behaviors, rather than different points on one developmental trajectory. Next, we show that solitary nests suffered significantly higher rates of nest failure than did social nests. Nest failure apparently resulted from solitary foundress mortality and subsequent brood orphanage. Social nests had significantly higher productivity, measured as new brood cells provisioned during the study, than did solitary nests. After accounting for nest failures, per capita productivity did not change with group size. Our results support key predictions of Assured Fitness Return models, suggesting such indirect fitness benefits favor eusocial nesting in M. genalis. We compared field collections of natural nests to our observation nest data to show that without accounting for nest failures, M. genalis appear to suffer a per capita productivity decrease with increasing group size. Calculating per capita productivity from collected nests without accounting for the differential probabilities of survival across group sizes leads to an overestimate of solitary nest productivity.

We censused 3201 trees in 20 1-ha plots and 38,250 seedlings in the central 64 m super(2) of each plot. We found significant differences in the species composition of the seedling bank between nine protected sites in the Barro Colorado Nature Monument and 11 hunted sites in the contiguous Parque Nacional Soberania. Lianas, species with large seeds, and species with seeds dispersed by bats, small birds, and mechanical means were all overrepresented at hunted sites. The latter two findings could also be evaluated relative to the species composition of reproductively mature adults for canopy trees. The tree species present in the seedling bank had significantly heavier seeds than the tree species present as adults at hunted sites but not at protected sites. The representation of seed dispersal modes among the species present in the seedling bank did not reflect pre-existing differences in the local species composition of adults. We hypothesize that hunting large seed predators favors large seeds by reducing predation and increasing survival. We also hypothesize that the harvest of large birds and mammals that disperse many seeds favors other species whose seeds are dispersed by bats, small birds, and mechanical means. This process also favors lianas because the seeds of disproportionate numbers of liana species are dispersed by wind.

Its taxonomic identity, however, is still ambiguous because this taxon has been distinguished by morphological criteria (numerous, strongly curved chambers, etc.), whereas the other species of Rotalipora are distinguished primarily by their apertural and ornamental characters (raised sutures, periumbilical ridges, etc.). The presence of strongly raised sutures throughout the umbilical and spiral sides has also been used to identify R. greenhornensis, but this criterion is troublesome as it also applies to its direct ancestor Rotalipora globotruncanoides. Reexamination of the holotype and observation of many topotypes and some North Atlantic and Pacific hypotypes reveals that, despite its remarkable morphological variability, R. greenhornensis is distinguishable by having umbilical sutures that are not fully raised, with the last several being depressed, and supplementary apertures that are umbilical in position and surrounded by a continuous series of closely-spaced periumbilical ridges. Moreover, reduction of the raised sutures tends to occur simultaneously on both the umbilical and spiral sides. Such apertural and ornamental characters of R. greenhornensis serve as its primary distinguishing features, allowing a clear-cut differentiation of this taxon from other species of Rotalipora, particularly the closely associated species R. globotruncanoides and plano-convex Rotalipora deeckei.

Synchrotron X-ray diffraction suggests that a displacive phase transition occurs when moganite is heated above approximately 570 K, with an increase in symmetry from I2/a to IMAB: In the present study, we employed hard-mode Raman spectroscopy to confirm the existence of the alpha -beta moganite transformation and to offer complementary insight into the transition mechanism. Our analysis of the displacement of the 501 Delta cm (super -1) symmetric stretching-bending vibration (B (sub 3g) mode) with changing temperature strongly supports the existence of a monoclinic-to-orthorhombic phase transition between 570 and 590 K. Between 593 and 723 K, however, the mode remained fixed at 496 Delta cm (super -1) . This behavior was repeated on cooling, but with a hysteresis of over 100 K. We offer three hypotheses that may explain this observation: (1) the intergrowth of nanoscale quartz lamellae within moganite may exert a strain that inhibits the transition; (2) the transition may exhibit a martensitic character marked by the co-existence of alpha - and beta -moganite over a finite temperature interval; and (3) the alpha - and beta -moganite transition may occur via an intermediate phase.

These values contrast with a similar study from a somewhat younger (mid-Artinskian) nearby site where analogous values are 2.55% and 31.8%, respectively. As at the younger site, when compared to all other co-occurring plant taxa, CBB pteridosperms were overwhelmingly herbivorized, particularly the peltasperm Autunia cf. conferta and the medullosan Odontopteris cf. lingulata, the latter preserving an exceptionally high herbivory level of 3.31%. These two host-plant taxa accounted for 96.8% of all herbivorized leaves and 96.4% of all leaf surface area removed by insects. For the bulk flora, four subgroups of feeding were documented: margin feeding (70.1% of all occurrences), hole feeding (24.1%), and minor skeletonization (earliest occurrence), and galling. Distinctive gall types, one on the midveinal region of A. cf. conferta and the other on a branchlet of Walchia piniformis (also occurring in the European Early Permian) add to an existing but depauperate insect gall record for the Pennsylvanian and Permian. Emerging evidence indicates that herbivory intensity was spatiotemporally heterogeneous across fluvially-associated landscapes during the Early Permian in both western Euramerica (Texas, USA) and western Gondwana (Parana Basin, Brazil), differing by an order of magnitude within each of these areas. Localities with the highest percentages of bulk leaf surface-area removed by herbivores in both realms ranged from 2.39 to 2.97%. This range approximates about a third of modern surface-area removal values by insect herbivores in both subtropical to tropical floras.

The Russell mine, one of the larger producers in North Carolina, is located in the central Uwharrie Mountains, and produced over 470 kg of gold. Ore grades averaged about 3.4 grams per tonne (g/t), with higher-grade zones reported. The Russell deposit is interpreted to be a sediment-hosted, gold-rich, base-metal poor, volcanogenic massive sulfide deposit in which gold was remobilized, in part, during Ordovician metamorphism. The ore was deposited syngenetically with laminated silt-stones of the late Proterozoic Tillery Formation that have been metamorphosed to a lower greenschist facies. The Tillery Formation regionally overlies subaerial to shallow marine rhyolitic volcanic and volcaniclastic rocks of the Uwharrie Formation and underlies the marine volcanic and sedimentary rocks of the Cid Formation. Recent mapping has shown that a rhyolitic dome near the Russell mine was extruded during the deposition of the lower part of the Tillery Formation, at about the same time as ore deposition. Relict mafic rock fragments present in the ore zones suggest contemporaneous bimodal (rhyolite-basalt) volcanism. The maximum formation age of the Russell deposit is younger than 558 Ma, which is similar to that of the larger, well known Brewer, Haile, and Ridgeway deposits of South Carolina. Gold was mined from at least six zones that are parallel to the regional metamorphic foliation. These strongly deformed zones consist of northeast-trending folds, high-angle reverse faults, and asymmetric doubly plunging folds overturned to the southeast. The dominant structure at the mine is an asymmetric doubly plunging anticline with the axis trending N45 degrees E, probably related to late Ordovician (456+ or -2 Ma) regional metamorphism and deformation. Two stages of pyrite growth are recognized. Stage 1, primary, spongy pyrite, is present in thin massive sulfide layers parallel to bedding and intergrown with pyrrhotite, chalcopyrite, sphalerite, and sparse arsenopyrite. Stage 2, secondary pyrite, is present as euhedral, idiomorphic rims on spongy pyrite and as veinlets that parallel the regional foliation. Stage 1 pyrite was deposited syngenetically or diagenetically during or soon after sedimentation. Stage 2 pyrite overgrowths and veins resulted from recrystallization or remobilization of stage 1 pyrite, probably during deformation related to Ordovician regional metamorphism. It is proposed that the spongy texture of the stage 1 pyrite represents nucleation and growth of pyrite on organic matter, possibly of bacterial origin. Other textures, such as geometric voids in spongy pyrite, As-rich zones surrounding central voids, 60-mu m ring structures composed of spongy pyrite, and layers of spongy pyrite interlayered with bedding laminations, also appear to indicate replacement of organic matter by pyrite. Stage 1 pyrite contains up to 0.06 wt percent gold. The delta (super 34) S values of pyrite in and near pyritic ore (3.5-4.5 per mil), in the rhyolite dome (5.1-5.4 per mil) and in the Tillery Formation (5.9-6.2 per mil) are interpreted to reflect mixing of sulfur derived from igneous and seawater sources. Whole-rock delta (super 18) O values of nearby unaltered mudstone are about 11 per mil whereas those from altered mudstone at the deposit are 7.4 to 10.6 per mil. The lower delta (super 18) O values are interpreted to indicate possible high-temperature exchange between relatively low delta (super 18) O hydrothermal fluids and the wall rocks. Gold, As, K, and Mo are enriched relative to the regional background in both the ore zones and in pyrite veins and disseminations in the nearby rhyolite dome, suggesting a possible genetic link between the rhyolitic volcanism and the gold mineralization.

In the following study, Gublerina cuvillieri and its proposed ancestor Heterohelix rajagopalani were picked from Ocean Drilling Program Hole 761B (Exmouth Plateau), and their relationship was evaluated using biometric analyses and morphological observations from SEM images. The phylogenetic relationship between G. cuvillieri and H. rajagopalani has been the subject of some debate. Gublerina cuvillieri was first described by Kikoine (1948) from southern France, and Govindan (1972) described Gublerina rajagopalani from southern India. Nederbragt (1991) has since suggested that G. rajagopalani actually belongs in another genus, Heterohelix. In this study, quantitative data from x-ray image measurements provide evidence that H. rajagopalani is the direct ancestor of G. cuvillieri. The measurement data for the two species are virtually identical for the biserial portion of the tests, indicating a close phylogenetic relationship. Heterohelix rajagopalani and G. cuvillieri diverge later in their ontogenetic history as expressed in G. cuvillieri by separation of the serial chambers, development of a multiserial stage, greater chamber number, and concentration of ornamentation elements in bands extending around the chamber edge. Isotope data indicates the two species lived at relatively the same water depth. This study is the beginning of a reevaluation of the gublerinid phylogenetic relationships.

Comparative physiology links paleontological and paleoenvironmental observations, supporting the hypothesis that an end-Permian trigger, most likely Siberian Trap volcanism, touched off a set of physically-linked perturbations that acted synergistically to disrupt the metabolisms of latest Permian organisms. Global warming, anoxia, and toxic sulfide probably all contributed to end-Permian mass mortality, but hypercapnia (physiological effects of elevated P (sub CO2) ) best accounts for the selective survival of marine invertebrates. Paleophysiological perspectives further suggest that persistent or recurring hypercapnia/global warmth also played a principal role in delayed Triassic recovery. More generally, physiology provides an important way of paleobiological knowing in the age of Earth system science.

The radar signals penetrate deep into the deposits (more than 3.7 kilometers). For most of the area, a reflection is detected at a time delay that is consistent with an interface between the deposits and the substrate. The reflected power from this interface indicates minimal attenuation of the signal, suggesting a composition of nearly pure water ice. Maps were generated of the topography of the basal interface and the thickness of the layered deposits. A set of buried depressions is seen within 300 kilometers of the pole. The thickness map shows an asymmetric distribution of the deposits and regions of anomalous thickness. The total volume is estimated to be 1.6X10 (super 6) cubic kilometers, which is equivalent to a global water layer approximately 11 meters thick.

The genus is monospecific, with Rugotruncana circumnodifer (Finlay, 1940) being the only species included within it. Taxonomic revision of the genus was made by examination of type specimens of all species assigned to Rugotruncana in the past. The genus is characterized by the presence of an imperforate band and a weakly to strongly developed double keel along the test periphery. In addition, detailed scanning electron microscope observations reveal that the test ornamentation is asymmetrical, with variably developed rugae and costellae being parallel to the periphery on the spiral side and meridional on the umbilical side. These features serve to distinguish Rugotruncana from Rugoglobigerina and GLOBOTRUNCANA: Based on the morphological features revealed by the detailed test ultrastructure and ornamentation observations, Rugotruncana is included within Family Rugoglobigerinidae.

Neutral dissolved Hg-sulfide complexes are readily available to Hg-methylating bacteria in culture, and thermodynamic models predict that inorganic Hg-sulfide complexes dominate dissolved Hg speciation under natural sulfidic conditions. However, these models have not been validated in the field. To examine the complexation of Hg in natural sulfidic waters, octanol/water partitioning methods were modified for use under environmentally relevant conditions, and a centrifuge ultrafiltration technique was developed. These techniques demonstrated much lower concentrations of dissolved Hg-sulfide complexes than predicted. Furthermore, the study revealed an interaction between Hg, dissolved organic matter (DOM), and sulfide that is not captured by current thermodynamic models. Whereas Hg forms strong complexes with DOM under oxic conditions, these complexes had not been expected to form in the presence of sulfide because of the stronger affinity of Hg for sulfide relative to its affinity for DOM. The observed interaction between Hg and DOM in the presence of sulfide likely involves the formation of a DOM-Hg-sulfide complex or results from the hydrophobic partitioning of neutral Hg-sulfide complexes into the higher-molecular-weight DOM. An understanding of the mechanism of this interaction and determination of complexation coefficients for the Hg-sulfide-DOM complex are needed to adequately assess how our new finding affects Hg bioavailability, sorption, and flux.

This research contributes an important comparative perspective on processes of complex sociopolitical organization practiced among mobile groups. This essay employs a novel approach to understanding the organizational techniques and methods of finance that supported large-scale imperial polities of eastern Eurasia, specifically those centered on the Mongolian steppe. Using full-coverage survey data from the northern Mongolian valley of Egiin Gol, we present the results of diachronic spatial and environmental analyses in order to evaluate current models for nomadic political economy. We argue that eastern Eurasian subsistence economics are best understood not as a single 'type' of production but as a productive process based on multiresource capacities (agro-pastoral, hunting, gathering, fishing) and the flexibility to readily adjust resource emphasis, degree of mobility, and specialization relative to a changeable environment. We offer a revised model for eastern steppe political integration emphasizing the spatial management of political relationships within a mobile setting. Our essay concludes with a brief overview of the potential for Eurasian steppe archaeology to contribute novel comparative insights for anthropologists studying the diversities and commonalities of complex social organization.

The caves vary in elevation; we suggest that the higher caves were formed and filled with sediments prior to the lower caves. The highest deposits, which are from Mohui Cave, contain hominoid teeth and other fossilized remains of mammalian taxa most similar to late Pliocene and early Pleistocene faunas. Wuyun Cave (~50m lower in elevation than Mohui) contains a late middle Pleistocene fauna, which is supported by U-series age constraints from 350 to 200ka. Lower Pubu Cave (~23m below Wuyun) is assigned to the late Pleistocene, while the Cunkong Cave (the lowest, ~2m lower elevation than Lower Pubu) preserves a Holocene fauna. The four faunal assemblages indicate species-level changes in Ailuropoda, Stegodon, and Sus, the appearance of Elephas, the local disappearance of Stegodon, and the migration of Equus hemionus to South China. These initial results of our work call into question the continued value of the Stegodon/Ailuropoda Fauna, a category long used to characterize the Pleistocene faunas of South China. Excavation of karstic caves of varying elevation within the basins of South China holds promise for defining local sequences of mammalian fossils that can be used to investigate faunal variations related to climate change, biogeographic events, and evolutionary change over the past two million years. Stable isotopic analysis of a small sample of mammalian teeth from Bubing Basin caves is consistent with 100% C"3 vegetation in the Bubing/Bose region, with certain @d13C values consistent with a canopied woodland or forest. A preliminary assessment of the hominoid teeth indicates the presence of diverse molar and premolar morphologies including dental remains of Gigantopithecus blacki and a sample with similarities to the teeth reported from Longgupo.

We used fertilization experiments in nitrogen (N)- and phosphorus (P)-limited mangrove forests to test the hypothesis that alleviating different kinds of nutrient limitation may have different effects on ecosystem structure and function in natural systems. We compared a broad range of ecological processes to determine if these systems have different thresholds where shifts might occur in nutrient limitation. Growth responses indicated N limitation in Avicennia germinans (black mangrove) forests in the Indian River Lagoon (IRL), Florida, and P limitation at Twin Cays, Belize. When nutrient deficiency was relieved, A. germinans grew out of its stunted form by increasing wood relative to leaf biomass and shoot length relative to lateral growth. At the P-limited site, P enrichment (+P) increased specific leaf area, N resorption, and P uptake, but had no effect on P resorption. At the N-limited site, +N increased both N and P resorption, but did not alter biomass allocation. Herbivory was greater at the P-limited site and was unaffected by +P, whereas +N led to increased herbivory at the N-limited site. The responses to nutrient enrichment depended on the ecological process and limiting nutrient and suggested that N-versus P-limited mangroves do have different thresholds. +P had a greater effect on more ecological processes at Twin Cays than did +N at the IRL, which indicated that the P-limited site was more sensitive to nutrient loading. Because of this sensitivity, eutrophication is more likely to cause a shift in nutrient limitation at P-limited Twin Cays than N-limited IRL.

Rapid assessment protocols for determining and monitoring the status of any given coral reef are provided and include measuring: (a) standing stocks of functional indicator groups, (b) herbivore populations, (c) water-column nutrient levels, (d) tissue C:N:P ratios, (e) algal physiological-response assays, and (f) herbivory assays. These measurements can reveal quantitative tipping-point levels beyond which resilience to undesirable phase shifts begins to become critically reduced. Universal tipping-point approximations are reviewed for inorganic nutrients, and posited for the first time for herbivory. 2. The relative roles of top-down and bottom-up controls in determining benthic community structure and the health of coral reefs are especially important management concerns. This paper specifically addresses the top-down effects of herbivory and bottom-up effects of nutrient enrichment on critical indicator groups, i.e. reef-building corals, crustose coralline algae, dense turf algae and frondose macroalgae. 3. A predominance of (a) massive corals and calcareous coralline algae relative to frondose macroalgae and algal turfs indicates a healthy spatially heterogeneous condition reflecting low nutrients and high herbivory. An abundance of (b) frondose macroalgae illustrates the least desirable condition of elevated nutrient levels and reduced herbivory, possibly reflecting pollution in concert with destructive herbivore fishing practices. High coverage of (c) coralline algae suggests healthy high herbivory levels, but problems with elevated nutrients that are inhibitory to some corals. Domination by (d) dense turf algae indicates desirably low nutrient levels, but an inadequate herbivory component. 4. The fast growth and turnover rates of fleshy algae compared to other reef organisms highlight their value as early warning indicators of reef degradation. 5. From a management perspective, levels of herbivory and nutrients rank among the most useful quantitative indicators of coral reef resilience; whereas, the degree of degradation and mortality are inferred from the above functional indicator groups of benthic primary producers.Published in 2006 by John Wiley & Sons, Ltd.

To determine if the A. ventricosus population in one major fishing ground, Las Perlas Archipelago, has recovered almost 15 years after that collapse, we interviewed fishermen, reviewed historical data about scallop export markets and fishing grounds, and assessed the state of the scallop population using traditional local trawling methods. During four expeditions (2000-2004), we intensively surveyed 183 trawling stations, which included the major shallow fishery sites as well as other deeper areas within the archipelago. We collected hundreds of relic adult and juvenile scallop shells, but we retrieved only 30 live individuals. This suggests that minimal recruitment has occurred in the archipelago and that the fishery remains collapsed. We argue that this population's failure to recover may be because of a lack of suitable available habitats for juveniles, predation and variation in local oceanographic conditions, as previously suggested. Further studies are needed to fully determine why the scallop population has failed to recover. Application of mariculture techniques may be required to restore the stock and repopulate A. ventricosus natural banks in Las Perlas Archipelago.

Specimens of Dyacopterus are sparsely represented in collections of world museums, which has hindered resolution of species limits within the genus. Based on our studies of most available museum material, we review the infrageneric taxonomy of Dyacopterus using craniometric and other comparisons. In the past, 2 species have been described--D. spadiceus (Thomas, 1890), described from Borneo and later recorded from the Malay Peninsula, and D. brooksi Thomas, 1920, described from Sumatra. These 2 nominal taxa are often recognized as species or conspecific subspecies representing these respective populations. Our examinations instead suggest that both previously described species of Dyacopterus co-occur on the Sunda Shelf-the smaller-skulled D. spadiceus in peninsular Malaysia, Sumatra, and Borneo, and the larger-skulled D. brooksi in Sumatra and Borneo. We further identify specimens of Dyacopterus from the large islands of Luzon and Mindanao in the Philippines as representatives of a distinctive new species, Dyacopterus rickarti. This new species differs from the Sundaic taxa in its much larger size, unique palatal ridge formula, and in qualitative craniodental features. The natural history of each species, so far as it is known, is briefly reviewed.

The highest density of nesting female leatherback sea turtles occurs in Gabon, which may host as much as 30% of the global nesting population (Sounguet et al. in press). Based on aerial surveys, up to 1,500 nests are laid per night during the peak nesting season along the entire coastline (Sounguet et al. in press). In addition to leatherbacks, green (Chelonia mydas), hawksbill (Eretmochelys imbricata), and olive ridley (Lepidochelys olivacea) sea turtles frequent the waters off the coast and have been documented nesting in Gabon (Formia 1999; Fretey 2001; Fretey et al. 2002).

Members of this complex are the most likely vectors of malaria in the past in southern Australia and are involved in the spread of myxomatosis among rabbits. In this, the first comprehensive molecular study of the Annulipes Complex, 23 ITS2 rDNA variants were detected from collections throughout Australia and Papua New Guinea, including diagnostic variants for the previously identified An. annulipes species A-G. Specimens of each ITS2 variant were sequenced for portions of the mitochondrial COI, COII and nuclear EF-1a genes. Partitioned Bayesian and Maximum Parsimony analyses confirmed the monophyly of the Annulipes Complex and revealed at least 17 clades that we designate species A-Q. These species belong to two major clades, one in the north and one mainly in the south, suggesting that climate was a driver of species radiation. We found that 65% (11) of the 17 sibling species recorded here had unique COI sequences, suggesting that DNA barcoding will be useful for diagnosing species within the Annulipes Complex. A comparison of the taxa revealed morphological characters that may be diagnostic for some species. Our results substantially increase the size of the subgenus Cellia in Australasia, and will assist species-level studies of the Annulipes Complex.

In the mid-1980s scientists estimated that coral cover was reduced by 50-100% in several countries across the region. Almost 20 years (2002) after the 1982-1983 event, we assessed the recovery of the virtually destroyed reefs at Cocos Island (Costa Rica), previously evaluated in 1987 and reported to have less than 4% live coral cover. We observed up to fivefold increase in live coral cover which varied among reefs surveyed in 1987 and 2002. Most new recruits and adults belonged to the main reef building species from pre-1982 ENSO, Porites lobata, suggesting that a disturbance as outstanding as El Nino was not sufficient to change the role or composition of the dominant species, contrary to phase shifts reported for the Caribbean. During the 1990s, new species were observed growing on the reefs. Notably, Leptoseris scabra, considered to be rare in the entire Pacific, was commonly found in the area. Recovery may have begun with the sexual and asexual recruits of the few surviving colonies of P. lobata and Pavona spp. and with long distance transport of larvae from remote reefs.

In previous research, captive passion-vine butterflies Heliconius mimetic in colour pattern were also mimetic in motion. Here, I investigate whether wing motion changes with the flight demands of different behaviours. If birds select for wing motion as a warning signal, aposematic butterflies should maintain wing motion independently of behavioural context. Members of one mimicry group (Heliconius cydno and Heliconius sapho) beat their wings more slowly and their wing strokes were more asymmetric than their sister-species (Heliconius melpomene and Heliconius erato, respectively), which were members of another mimicry group having a quick and steady wing motion. Within mimicry groups, wing beat frequency declined as its role in generating lift also declined in different behavioural contexts. In contrast, asymmetry of the stroke was not associated with wing beat frequency or behavioural context-strong indication that birds process and store the Fourier motion energy of butterfly wings. Although direct evidence that birds respond to subtle differences in butterfly wing motion is lacking, birds appear to generalize a motion pattern as much as they encounter members of a mimicry group in different behavioural contexts.

Plant communities responded rapidly with major compositional turnover. The long-term effects on tropical vegetation communities that stem from the brief period of global warming are unclear. We present pollen data from the paratropical US Gulf Coast (eastern Mississippi, western Alabama and Georgia), which had background Palaeogene mean annual temperatures of 26-27 degrees C. Sporomorph data (pollen and spores) demonstrate that taxonomic diversity increases over c. 1 Ma in the Late Palaeocene but this trend is replaced, with the first occurrences of taxa that mark the Early Eocene, by a pronounced extinction into the Early Eocene (c. 20% of the palynoflora). Taxonomic diversity also decreases by up to 38% in the Early Eocene. The timing of the extinction is not clearly resolved but may be restricted to the earliest part of the Early Eocene. Two richness estimators (Chao 2 and Jackknife 2) both demonstrate that Late Palaeocene samples contain significantly more taxa than those in the Early Eocene. Extinction on the US Gulf Coast proves that ancient tropical ecosystems were highly susceptible to changes in diversity mediated directly or indirectly by environmental change even during equable greenhouse climates in the early Palaeogene.

Researchers have used these data to measure changes in water mass over various regions, including the global oceans and continental ice sheets covering Greenland and Antarctica. However, GRACE data must be smoothed in these analyses and the effects of geocenter motions are not included. In this study, we examine what effect each of these has in the computation of ocean mass trends using a simulation of ice melting on Greenland, Antarctica, and mountain glaciers. We find that the recovered sea level change is systematically lower when coefficients are smoothed and geocenter terms are not included. (mod. journ. abst.)

There are two geochemical types of granitic pegmatites, LCT and NYF. LCT pegmatites are rich in lithium (Li), cesium (Cs), and tantalum (Ta) and are usually associated with orogenic events. NYF pegmatites are related to anorogenic granites and are enriched in niobium (N), yttrium (Y), and fluorine (F). Topaz is a fluorine-rich mineral that commonly occurs in pegmatites; however, topaz is more common in NYF pegmatites than in LCT pegmatites. The focus of this project was to examine the changes in topaz crystal structure caused by F-OH substitution and to investigate the structural changes due to temperature in order to determine if there are structural differences between topaz from LCT pegmatites and topaz from NYF pegmatites. In this study, 32 topaz samples from 26 localities were analyzed for unit-cell parameters, fluorine content, trace element content, and heating effects. Cell parameters were obtained by using X-ray diffraction, and fluorine content was obtained by electron microprobe analysis. The b unit-cell dimension decreases with increasing F content. There is a less defined decreasing trend in the a-unit cell dimension as F content increases. No correlation was found between the c-cell dimension and any cell-dimension or compositional variation. Plots of the pegmatitic topaz from this study show distinct and separate linear trends between NYF and LCT pegmatites when comparing the b-unit cell dimension to the F content. Trace element analysis by X-Ray fluorescence shows the presence of Ge, Cr, Pb, Ga, W, and Rb but yields no correlation between trace elements and unit cell variations. Selected samples were chosen for a heat study. Samples were heated at 700 degrees C for 1 hour. After heating, the unit cell volume of the topaz generally decreased but no trends separating NYF pegmatites from LCT pegmatites were found.

In support of that demarcation criterion, I evidence the breadth and strength of modernity's presupposition of the primacy of science to and for technology by showing its preposterous hold upon social theorists-Marx, Veblen, Dewey-whose principles logically required the reverse, viz. the primacy of practice; upon 19th and 20th century engineers and industrialists, social actors whose practical interests likewise required the reverse; and upon the principal theorizers in the 1970s of the role of science in late 20th century technology and society. The reversal in primacy between science and technology ca 1980 came too unexpectedly, too quickly, and, above all, too unreflectively to have resulted from the weight of evidence or the force of logic. Rather, it was a concomitant of the onset of postmodernity. Oddly, historians of technology have remained almost wholly unacknowledging of postmodernity's epochal elevation of the cultural standing of the subject of their studies, and, specifically, have ignored technology's elevation relative to science. This I attribute to the ideological character of that discipline, and, specifically, to its strategy of ignoration of science.

If native Amazonian sociality is all about predatory affinity or, alternatively, convivial consanguinity, why do native Amazonians constantly strive to establish social relationships with people with whom they are related neither as kin nor as affines? The comparative analysis of intertribal trading partnerships, shamanic networks, and mystical associations allows the author to examine the mechanisms by which hostile or potentially hostile relations between strangers - non-relatives - are transformed into relations of amicability. Special emphasis is placed on the role played by 'trust' and 'spaces of trust' in the creation of non-kin-based social networks. In brief the article analyses the little-studied issue of 'friendship', viewing it as an alternative to kinship and affinity in the construction of Amerindian societies and multi-ethnic polities. // ABSTRACT IN FRENCH: L'auteur explore la nature de la socialité et de l'altérité chez les peuples indigènes d'Amazonie. Si la socialité des natifs amazoniens n'est vraiment qu'une affaire d'affinité prédatrice ou de consanguinité conviviale, pourquoi cherchent-ils sans relâche à nouer des relations sociales avec des gens auxquels ils ne sont apparentés ni par le sang ni par alliance? L'analyse comparative des partenariats d'échanges intertribaux, des réseaux chamaniques et des associations mystiques permet à l'auteur d'examiner les mécanismes par lesquels les relations hostiles ou potentiellement hostiles entre étrangers (non apparentés) sont transformées en relations amicales. Une attention particulière est portée au rôle joué par la « confiance » et les « espaces de confiance » dans la création de réseaux sociaux non basés sur la parenté. En résumé, l'article analyse la question peu étudiée de « l'amitié », considérée comme une alternative à la parenté dans la construction des sociétés et des entités politiques multiethniques amérindiennes.

By choosing a lectotype and studying it along with the paralectotypes, we find that L. Isodictyalis, subgenus Lissodendoryx, is a Caribbean sponge characterized by smooth megascleres, ectosomal tylotes and choanosomal styles, and one size-class of microscleres comprising arcuate isochelae and sigmas. Having determined these characteristics, we re-erect Lissodendoryx (Lissodendoryx) carolinensis (previously synonymized with L. Isodictyalis), with the same smooth megascleres but two distinct size categories of microscleres, isochelae and sigmas; and we add a new western Atlantic species, Lissodendoryx (L.) spinosa sp. nov., with coarse spines on the megasclere terminals and with two size-classes of isochelae and sigmas. Other species in the region are Lissodendoryx (L.) colombiensis, with smooth tylotes and robust strongyles, and two categories of microscleres (isochelae and sigmas) accompanied by conspicuous raphids arranged in trichodragmas; Lissodendoryx (L.) strongylata, with smooth tylotes and slim strongyles, one size-class each of isochelae and sigmas, rare and very thin raphids. Lissodendoryx sigmata is here assigned to the subgenus Anomodoryx, with smooth tylotes exclusively as megascleres, two size-classes of isochelae, and one or two sizes of sigmas; it may represent a species complex far more diverse than previously thought. To this subgenus we add another species, Lissodendoryx (A.) amphispinulata sp. nov., characterized by fine spines ornamenting both tyles of part of the tylotes. A third subgenus, Ectyodoryx, is represented by Lissodendoryx (E.) acanthostylota sp. nov., with smooth tylotes and finely spined acanthostyles in two size-classes, as well as two size-classes each of isochelae and sigmas as microscleres. All species studied alive occur in shallow lagoon habitats with mangroves and sea grass (Thalassia) but museum specimen records show that some may reach a depth of 60 m.

It is therefore important to be able to predict both where species may become established and their capacity to spread within recipient regions. Here, we use a new method to assess potential for intraregional spread of a marine crab introduced to North America, Carcinus maenas. We determined survivorship and development rates throughout a range of temperatures in the laboratory for C. maenas larvae from non-native populations on the Atlantic and Pacific coasts of North America. The larvae exhibited narrower physiological tolerances than adults, and no lab-cultured larvae completed larval development below 10.0 degree C or above 22.5 degree C. Survivorship peaked at intermediate water temperatures of 12.5-20.0 degree C, and development time decreased with increasing temperatures within this range. Based upon these laboratory development rates, we used nearshore sea-surface temperature data from both coasts of North America to predict development times required for larvae at different months and sites. Taken together, survivorship and development data indicate that C. maenas has the capacity to continue its northward spread and establish populations at numerous additional sites in North America. Moreover, decadal temperature data at two Alaskan sites predicted little variability in development duration across years, suggesting that development duration predictions are robust to interannual water temperature differences.

AN - 20491718; 7767884 AB - Jehl (1988) observed that the departure of Eared Grebes Podiceps nigricollis from Mono Lake, California, a major fall staging area, did not occur in relation to time of year or weather but was initiated after the density of brine shrimp (Artemia monica)-the major prey-fell below a predictable threshold. Although Caudell and Conover (2006) found no such relationship at Great Salt Lake, the other major staging area, reevaluation of their data indicates that the threshold concept applies there as well. Substantial differences in the staging ecology of Eared Grebes at the two lakes remain to be demonstrated.

Phylogenetic analyses of separate and combined molecular datasets yielded well-supported and largely congruent trees delineating 13 genetically divergent and morphologically distinctive upper Sacramento basin lineages, which we describe as new species. These include two groups of closely related and geographically proximal species that are further united by unique radular or shell features. Most of these novelties have narrow geographical distributions and are restricted to headspring areas, whereas several are more wide ranging and typically occupy larger, well-integrated habitats. The highly endemic fauna of upper Sacramento River pebblesnails is not a single species flock, but instead a polyphyletic assemblage spread among four separate clades. Our phylogeny, together with the application of a COI molecular clock for Fluminicola, suggests that upper Sacramento River clades originated as a result of late Neogene separation of this basin from neighbouring regions (northwestern Great Basin, Klamath River basin), which is consistent with previous biogeographical hypotheses based on the distributions of fishes. The upper Sacramento River pebblesnails evolved in association with the complex late Cenozoic history of regional landscape and drainage and diversification was also facilitated by the invasion of and adaptation to insular spring habitats. Our findings are consistent with the generally limited dispersal ability and geologically ancient (mid-Tertiary) age of this genus and imply that other portions of northwestern North America may also harbour a large number of undescribed pebblesnail species.Journal compilation [copy 2007 The Linnean Society of London, Zoological Journal of the Linnean Society, 2007, 149, 371-422.

These webs completely lacked sticky silk, so their stabilimenta could not function to attract prey. Some non-orbs were built by spiders when their orb webs are damaged. These observations contradict the prey attraction camouflage hypothesis for stabilimentum function, but are compatible with the spider camouflage and web advertisement to avoid web destruction hypotheses. RESUMENTanto el uloborido Philoponella vicina como el araneido Gasteracantha cancriformis colocan stabilimentos de seda en 'telas' no-orbiculares que consisten de una pocas lineas. Estas telas carecen de hilos pegajosos, y no funcionan para capturar presas; por lo tanto, sus estabilimenta no funcionan para atraer presas. Algunas de estas telas no-orbiculares son construidas despues de que se dana la tela orbicular. Estas observaciones contradicen la hipotesis de que los estabilimentos funcionan para atraer presas; son compatibles con las hipotesis de que los estabilimentos funcionan para camuflar la arana, o para avisar a animales grandes y asi evitar que se danen las telas.

Some recently proposed strategies to reverse this trend have included the restoration of bivalve suspension feeders as an ecological tool for reducing phytoplankton biomass. The ecological benefits accruing from such bivalve restoration will be dependent on the characteristics of the estuary, as well as how restoration is implemented. We developed a filtration model to estimate the effect of bivalve restoration on the rate of phytoplankton removal over a range of spatial and temporal scales and used it to compare alternate restoration strategies for the eastern oyster Crassostrea virginica in Chesapeake Bay, USA. Model results suggested that currently accepted restoration goals for oysters in the bay are unlikely to result in significant bay-wide reductions in phytoplankton biomass. This is partially due to low current biomass targets for oyster restoration, but also important are several spatial and temporal mismatches between oyster and phytoplankton biomass that may limit the ecological benefit of oyster restoration. Our model did predict important increases in phytoplankton removal by oysters at the tributary scale, and this effect was dependent on where oyster restoration was achieved and whether restoration and management plans affected the size distribution of oysters. Our findings suggest that the ecological benefit of restoring bivalve populations are variable, and a comparative model analysis of restoration plans in particular systems can be highly beneficial to maximizing the benefit-to-cost ratio of restoration efforts intended to reduce the negative effects of cultural eutrophication.

Some marine animals have contrasting color patterns and chemical defenses but few studies have tested the behavior of marine predators in response to aposematic coloration. In this study we tested fish feeding behavior in response to different types of cues including contrasting color patterns and sponge and nudibranch chemical extracts in the field at 2 reefs on Guam. Using agar-based food to keep food quality consistent, chemical extracts and 2 out of 5 contrasting color patterns reduced feeding by natural assemblages of reef fish at both reefs. Phyllidia varicosa (from Palau), P. elegans (Guam) and Phyllidiella pustulosa (Palau) crude extracts deterred feeding by fish, but P. pustulosa extracts from Guam did not. To determine if a chemical extract can act as an olfactory defense we videotaped fish behavior as they approached food containing nonpolar extracts of Acanthella cavernosa, the dietary sponge of Phyllidiella granulatus. Fish approached and then tasted the food with the chemical extract significantly less often than the control and the crude extract of another sponge Stylissa massa. In feeding assays with a contrasting color pattern combined with the chemical extract at natural concentrations, fish were deterred by the extract regardless of the color pattern. At half natural concentration only the chemical extract and the contrasting color pattern together significantly decreased fish feeding. Reef fish can use multimodal signals including visual, taste and olfactory cues to avoid marine benthic invertebrates.

Efforts to explain and predict invasion outcomes have been limited primarily to terrestrial and freshwater ecosystems. Invasions are also common in coastal marine ecosystems, yet to date predictive marine invasion models are absent. Here we present a model based on biological attributes associated with invasion success (establishment) of marine molluscs that compares successful and failed invasions from a group of 93 species introduced to San Francisco Bay (SFB) in association with commercial oyster transfers from eastern North America (ca. 1869 to 1940). A multiple logistic regression model correctly classified 83% of successful and 80% of failed invaders according to their source region abundance at the time of oyster transfers, tolerance of low salinity, and developmental mode. We tested the generality of the SFB invasion model by applying it to 3 coastal locations (2 in North America and 1 in Europe) that received oyster transfers from the same source and during the same time as SFB. The model correctly predicted 100, 75, and 86% of successful invaders in these locations, indicating that abundance, environmental tolerance (ability to withstand low salinity), and developmental mode not only explain patterns of invasion success in SFB, but more importantly, predict invasion success in geographically disparate marine ecosystems. Finally, we demonstrate that the proportion of marine molluscs that succeeded in the latter stages of invasion (i.e. that establish self-sustaining populations, spread and become pests) is much greater than has been previously predicted or shown for other animals and plants.

As a result, migration routes for an entire migratory avifauna can encompass broad geographic areas, making it impossible to protect continuous stretches of habitat sufficient to connect the wintering and breeding grounds for most species. Consequently, ways to enhance habitats converted for human use (i.e. For pasture, crop cultivation, human settlement) as stopover sites for migrants are especially important. Shelterbelts around pastures and fields, if planted with species targeted to support migrant (and resident) bird species that naturally occupy mature forest habitats and that are at least partially frugivorous, could be a powerful enhancement tool for such species, if the birds will enter the converted areas to feed. I tested this approach for Nearctic migrant birds during the spring migration through an area in Chiapas, Mexico. Mature forest tree species whose fruits are eaten by birds were surveyed. Based on life form, crop size and fruit characteristics, I selected three tree species for study: Cymbopetalum mayanum (Annonaceae), Bursera simaruba (Burseraceae) and Trophis racemosa (Moraceae). I compared the use of fruits of these species by migrants and residents in forest with their use of the fruits of isolated individuals of the same species in pasture and cropland. All three plant species were useful for enhancing converted habitats for forest- occupying spring migrants, although species differed in the degree to which they entered disturbed areas to feed on the fruits. These tree species could probably enhance habitats for migrants at sites throughout the natural geographic ranges of the plants; in other geographic areas for other target bird groups, other tree species might be more appropriate.

The specimen from Nhatrang Bay was collected from a crinoid host. The new species is unique within the genus Athanas in having non-enlarged, symmetrical chelipeds ending in a peculiar claw with duckbill-shaped fingers, and the 3rd maxilliped having a broadened ultimate segment, distally armed with a row of strong spines. It is closely related to A. ornithorhynchus Banner and Banner, 1973, known as a facultative symbiont of filter-feeding brittle stars. An earlier report of a crinoid-associated Athanas (Bruce 1987) suggests that A. anatidactylus sp. nov. may also occur on the Great Barrier Reef, Australia.

Locations in a wide geographical area with a range of environmental variables were selected for patch-occupancy surveys using elephant dung to assess seasonal presence and absence of elephants. Patch-occupancy procedures allowed for covariate modelling evaluating hypotheses for both occupancy in relation to human activity and ecological features, and detection probability in relation to vegetation density. The best fitting models for old and fresh dung data sets indicate that (1) detection probability for elephant dung is negatively related to the relative density of the vegetation, and (2) human activity, such as presence and infrastructure, are more closely associated with elephant distribution patterns than are ecological features, such as the presence of wetlands and preferred fresh fruit. Our findings emphasize the sensitivity of elephants to human disturbance, in this case infrastructure development associated with gas and oil production. Patch-occupancy methodology offers a viable alternative to current transect protocols for monitoring programs with multiple covariates.

We examined these alternatives for the major episode of Caribbean extinction 2 million years ago (Ma). Isolation of the Caribbean from the Eastern Pacific by uplift of the Panamanian Isthmus was associated with synchronous changes in Caribbean near shore environments and community composition between 4.25 and 3.45 Ma. Seasonal fluctuations in Caribbean seawater temperature decreased 3-fold, carbonate deposition increased, and there was a striking, albeit patchy, shift in dominance of benthic ecosystems from heterotrophic mollusks to mixotrophic reef corals and calcareous algae. All of these changes correspond well with a simple model of decreased upwelling and collapse in planktonic productivity associated with the final stages of the closure of the isthmian barrier. However, extinction rates of mollusks and corals did not increase until 3-2 Ma and sharply peaked between 2 and 1 Ma, even though extinction overwhelmingly affected taxa commonly associated with high productivity. This time lag suggests that something other than environmental change per se was involved in extinction that does not occur as a single event. Understanding cause and effect will require more taxonomically refined analysis of the changing abundance and distribution patterns of different ecological guilds in the 2 million years leading up to the relatively sudden peak in extinction.

We analyzed a photograph of a bear skull taken in 1910 at an Innu camp in the Labrador interior (east of the George River), which appears to be that of a grizzly bear. Coupled with previously unpublished historical accounts by Lucien Turner (Smithsonian naturalist in northern Quebec, 1881-83) and William Duncan Strong (anthropologist in Labrador, 1928-29), Innu oral history accounts, and archaeological evidence, this photograph further substantiates the theory that a small number of grizzly bears were present in the Quebec-Labrador peninsula and survived into the 20th century.

Our statistical and discriminant function analyses of shell variation among the disjunct populations of this species indicate that Mexican specimens differ in their morphometry from those of the United States and can be diagnosed by several characters. We also analyzed variation in the mitochondrial genome by sequencing 658 bp of mitochondrial COI from populations of A. pecos, representatives of the other three North American species of Assiminea, and several outgroups. Our results indicated substantial divergence of the Mexican population of A. pecos, which was consistently depicted as a monophyletic unit nested within or sister to the shallowly structured group comprised of American members of this species. Consistent with our findings, we describe the Mexican population as a new species, which is provisionally placed in the large, worldwide genus Assiminea pending further study of the phylogentic relationships of the North American assimineids. Our molecular data suggest that the Rio Grande region assimineids, which are among the few inland members of the otherwise estuarine subfamily Assimineinae, diverged from coastal progenitors in the late Miocene, with subsequent Pleistocene vicariance of Mexican and American species perhaps associated with development of the modern, lower course of the Rio Grande.

These species have become dominate in coastal embayments and marinas but are usually absent from more open water coastal areas. A colonial ascidian, Didemnum sp. has invaded southern New England during the past 10 years and we first observed this species in eastern Long Island Sound in 2000. It has become the dominant at several field sites while remaining in low abundance at others. We conducted an experiment at two places, a protected marina and an open coast site, to examine its ability to compete with the established fouling community. Small colonies of Didemnum were transplanted onto panels with communities that varied in age from one to four weeks old and these treatments along with controls with only Didemnum were exposed at both sites. In most treatments Didemnum became a dominant species in the communities at both sites but it reached higher abundances at the open coast site. Potential causes of the observed differences are predation on other species of ascidians at the open coast site reducing recruitment of these species and competition, lower tolerance for elevated temperatures at the marina site, or other environmental parameters that might affect growth rates.

The link between disturbance and invasion potential has rarely been studied in the marine environment where dominance hierarchies, dynamics of larval supply, and resource acquisition may differ greatly from terrestrial systems. In this study, hard substrate marine communities in Long Island Sound, USA were used to assess the effect of disturbance on resident species and recent invaders, ascidian growth form (i.e. colonial and solitary growth form), and the dominant species-specific responses within the community. Community age was an additional factor considered through manipulation of 5-wk old assemblages and 1-yr old assemblages. Disturbance treatments, exposing primary substrate, were characterized by frequency (single, biweekly, monthly) and magnitude (20%, 48%, 80%) of disturbance. In communities of different ages, disturbance frequency had a significant positive effect on space occupation of recent invaders and a significant negative effect on resident species. In the 5-wk community, magnitude of disturbance also had a significant effect. Disturbance also had a significant effect on ascidian growth form; colonial species occupied more primary space than controls in response to increased disturbance frequency and magnitude. In contrast, solitary species occupied significantly less space than controls. Species-specific responses were similar regardless of community age. The non-native colonial ascidian Diplosoma listerianum responded positively to increased disturbance frequency and magnitude, and occupied more primary space in treatments than in controls. The resident solitary ascidian Molgula manhattensis responded negatively to increased disturbance frequency and magnitude, and occupied less primary space in treatments than in controls. Small-scale biological disturbances, by creating space, may facilitate the success of invasive species and colonial organisms in the development of subtidal hard substrate communities.

Many field studies have found that elevated CO sub(2) leads to higher carbon assimilation by plants, and others suggest that this can lead to higher carbon storage in soils, the largest and most stable terrestrial carbon pool. Here we show that 6 years of experimental CO sub(2) doubling reduced soil carbon in a scrub-oak ecosystem despite higher plant growth, offsetting approximately 52% of the additional carbon that had accumulated at elevated CO sub(2) in aboveground and coarse root biomass. The decline in soil carbon was driven by changes in soil microbial composition and activity. Soils exposed to elevated CO sub(2) had higher relative abundances of fungi and higher activities of a soil carbon-degrading enzyme, which led to more rapid rates of soil organic matter degradation than soils exposed to ambient CO sub(2). The isotopic composition of microbial fatty acids confirmed that elevated CO sub(2) increased microbial utilization of soil organic matter. These results show how elevated CO sub(2), by altering soil microbial communities, can cause a potential carbon sink to become a carbon source.

As the substratum at this site was a conglomerate of materials, we hypothesized that the observed pattern was the result of differences in substratum preferences, and/or negative interactions between the 2 species, or both. We used manipulative field experiments to test these hypotheses, and then generalized our findings with surveys across several sites that differed in substratum type and abundances of barnacles and limpets. The limpet recruited in highest numbers to light-colored substrata. The barnacle settled in highest numbers on rough substrata, with a trend toward higher settlement on dark-colored substrata. Surprisingly, in experimental plots, recruitment of the barnacle was positively correlated with the density of the limpet. In contrast, limpet densities increased in experimental plots from which barnacles had been removed. Thus the pattern at this site appears to result from a combination of substratum preferences and interactions between the 2 species. These experiments and surveys of other intertidal sites on Oahu suggest that (1) limpets and barnacles have little effect on each other at low densities, (2) at higher densities limpets facilitate settlement of barnacles, but barnacles have a negative effect on limpets, and (3) substratum type can mediate the density-dependent interactions between these 2 species by affecting their settlement patterns.

Direct, experimentally controlled comparisons of endophyte free (E-) and endophyte containing (E+) plant tissues in T. cacao show that foliar endophytes (FEF) that commonly occur in healthy host leaves enhance host defenses against foliar damage due to the pathogen (Phytophthora palmivora). Similarly, root inoculations with commonly occurring AMF also reduce foliar damage due to the same pathogen. These results suggest that endophytic fungi can play a potentially important mutualistic role by augmenting host defensive responses against pathogens. There are two broad classes of potential mechanisms by which endophytes could contribute to host protection: (1) inducing or increasing the expression of intrinsic host defense mechanisms and (2) providing additional sources of defense, extrinsic to those of the host (e.g., endophyte-based chemical antibiosis). The degree to which either of these mechanisms predominates holds distinct consequences for the evolutionary ecology of host-endophyte-pathogen relationships. More generally, the growing recognition that plants are composed of a mosaic of plant and fungal tissues holds a series of implications for the study of plant defense, physiology, and genetics.

The narratives of mischief & the gender ambiguity of the Santo Nino or the Holy Child Jesus, the centre of Ati-atihan's religious veneration, further enabled Diangson to interact with Kalibo's Roman Catholicism. Through an analysis of Diangson & his participation in the festival, this article exposes how ordinary individuals in extraordinary events localise their faith through cross-dressing & dance performance. Seen throughout the Philippines, these processes of mimicry & gender transformation transport individuals into zones of ambivalence & contradictions in which they are able to navigate through the homogenising discourse of their culture & the Church's homogenising myth of Roman Catholicism.

Potassium- and Ba-birnessite, like Na-birnessite, were found to have triclinic symmetry. Rietveld analyses of the XRD patterns for K- and Ba-exchanged birnessite revealed decreases in the a, c, and beta unit-cell parameters, with a decrease of 1.7 and 0.5%, respectively, in unit-cell volume relative to Na-birnessite. Fourier electron difference syntheses revealed that the changes in the configuration of the interlayer species, and the charge, size, and hydration of the substituting cations, serve as the primary controls on changes in unit-cell parameters. Split electron density maxima with centers at (0 0 0.5) were present for Na, K, and Ba end-members; however, with increased substitution of K (super +) for Na (super +) , the axis connecting the split-site maxima rotated from an orientation parallel to the b-axis to along the a-axis. Substitution of Ba (super 2+) for Na (super +) did not result in rotation, but splitting of the interlayer site was more pronounced.

Here, we report a genus-specific starch morphotype that provides a means to identify chili peppers from archaeological contexts and trace both their domestication and dispersal. These starch microfossils have been found at seven sites dating from 6000 years before present to European contact and ranging from the Bahamas to southern Peru. The starch grain assemblages demonstrate that maize and chilies occurred together as an ancient and widespread Neotropical plant food complex that predates pottery in some regions.

However, heliocentric distance, and thus surface temperature, has a significant effect on the spectra of olivine-rich asteroids. We show that composition and temperature complexly interact spectrally, and must be simultaneously taken into account in order to infer olivine composition accurately. We find that most (7/9) of the olivine-dominated asteroids are magnesian and thus likely sampled mantles differentiated from ordinary chondrite sources (e.g., pallasites). However, two other olivine-rich asteroids (289 Nenetta and 246 Asporina) are found to be more ferroan. Melting models show that partial melting cannot produce olivine-rich residues that are more ferroan than the chondrite precursor from which they formed. Thus, even moderately ferroan olivine must have non-ordinary chondrite origins, and therefore likely originate from oxidized R chondrites or melts thereof, which reflect variations in nebular composition within the asteroid belt. This is consistent with the meteoritic record in which R chondrites and brachinites are rare relative to pallasites.

We find evidence of spatial spillovers from roads in the Brazilian Amazon: deforestation rises in the census tracts that lack roads but are in the same county as and within 100 km of a tract with a new paved or unpaved road. At greater distances from the new roads the evidence is mixed, including negative coefficients of inconsistent significance between 100 and 300 km, and if anything, higher neighbor deforestation at distances over 300 km.

Now, just over two years later, questions raised by the interpretation of the fossil abound. In a series of recent papers, critics have questioned the interpretation of the small brain volume of the fossil as that of a new hominin species, suggesting instead that it was due to microcephaly. The arguments raised by critics and advocates alike prompt a re-examination of ideas about what is possible during the evolution of the brain.

AN - 20014586; 8238805 AB - Tropical forests are the most biologically diverse and ecologically complex of terrestrial ecosystems, and are disappearing at alarming rates. It has long been suggested that rapid forest loss and degradation in the tropics, if unabated, could ultimately precipitate a wave of species extinctions, perhaps comparable to mass extinction events in the geological history of the Earth. However, a vigorous debate has erupted following a study by Wright and Muller-Landau that challenges the notion of large-scale tropical extinctions, at least over the next century. Here, I summarize this controversy and describe how the debate is stimulating a serious examination of the causes and biological consequences of future tropical deforestation.

We used regular and high-speed video of tethered ostracodes to document locomotion in the cypridoidean species Cypridopsis vidua. Swimming in this species is drag-based, with thrust provided by both antennulae and antennae. About 15 complete power and recovery strokes occur per second; maximal speeds for the limb tips were about 30 mm/s for the antennulae and 50 mm/s for the antennae. These speeds correspond to Reynolds numbers on the order of 10 super(-1) to 10 super(0) for the limb tips and 10 super(-2) to 10 super(-1) for the setae that extend outward from the swimming limbs and provide much of the surface area of the limb. The strokes of the four thrust-producing limbs are coordinated in a manner that seems to be unique among aquatic arthropods. When viewed from the anterior, power strokes are synchronized diagonally: left antennula and right antenna power strokes start at the same time and terminate just as the power strokes for the right antennula and left antenna begin. Because power strokes occur throughout the stroke cycle, swimming in this species is smoothly continuous, without the rapid accelerations and decelerations characteristic of most small aquatic arthropods.

This study presents the beginning of a leaf litter ant dataset for Guyana. Following the ants of the leaf litter protocol, ants were extracted from sifted leaf litter sampled along eight transects from across Guyana. A total of 230 species were collected from 44 genera. Of those 230 species, 122 species (ca. 53%) were found at only one site. Out of the 122 species found at only one site, 43 species (ca. 19%) were singletons, being known from only one specimen. Using a cluster analysis, faunistic composition was compared among sites. While the lowland sites accounted for the highest species richness, Mt. Ayanganna possessed an especially distinctive ant fauna and may represent a center of endemism. Three leaf litter ant communities were identified: lowland and two Mt. Ayanganna communities, mid-elevation and upper elevation. Recent mining operations on Mt. Ayanganna threaten its pristine nature and this study confirms the need for further biological study of the area. With upwards of 70% of its area still forested Guyana has the opportunity to preserve its biological heritage before widespread deforestation occurs. If expanded, this leaf litter ant dataset will be increasingly useful for country-wide conservation planning.

We here investigated the origin and number of introductions of the endemic Hawaiian Silene based on phylogenetic relationships inferred from DNA sequences from both the plastid (the rps16 intron) and the nuclear (ribosomal internal transcribed sequences, ITS, and intron 23 of the RPB2 gene) genomes. Silene antirrhina, a widespread weedy American annual, is strongly supported as sister to a monophyletic group consisting of the Hawaiian Silene, indicating a single colonization event. There are no obvious morphological similarities between S. antirrhina and any of the species of Hawaiian SILENE: Our results suggest an American origin for the Hawaiian endemics because that would require only a single trans-ocean dispersal. Two of the Hawaiian endemics (S. struthioloides and S. hawaiiensis) that form a subclade in the analyses have evolved woodiness after introduction to the Hawaiian Islands. Our results contribute to other recent results based on molecular phylogenetics that emphasize the American continent as a source area for the Hawaiian flora and support a striking morphological radiation and evolution of woodiness from a single introduction to the archipelago.

AN - 860391354; 14589135 AB - Ships' ballast water is a major source of biological invasions in coastal systems and contains a diversity of microorganisms, yet their population dynamics remain largely unexplored. We measured temporal changes in total bacteria concentration in 75 ballast tanks (34 with mid-ocean exchange and 41 unexchanged controls) across 21 ocean voyages, from multiple departure ports (5% of Mediterranean source, including Fos-sur-Mer and Tel Aviv) and representing all seasons. Bacteria concentration differences were tested as a function of depth, time, ballast management and season. Total bacteria decreased significantly over time, and the decrease was significantly greater in exchanged tanks. Increases over time occurred occasionally but infrequently in a few tanks (4% for both control and exchanged), suggesting growth (incubation). Across tanks, there was not a significant difference due to depth, as most tanks (85% controls and 89% exchanged) showed no vertical stratification. Overall, there were no significant seasonal effects in total bacteria dynamics across ballast tanks.

It is thus understandable that the reconstruction of the Proto-Algonquian inflections of the indicative mode of the independent order has attracted so much attention. Originally this mode provided the verb in the commonest type of declarative sentence, as it does in most of the languages, but Bloomfield (1946:97-99) was unable to reconstruct full paradigms, noting that the four languages he used (Meskwaki, Cree, Menominee, & Ojibwe) "disagree as to the plural forms of first & second persons" & in transitive verbs also in the third person. A reconstruction proposed to account for all forms in all languages (Goddard 1967, 1974, 1979b, 2000) has been criticized & revised by Proulx (1990, summarizing his earlier work) & Pentland (1999). This paper presents a new revision of the reconstruction, synthesizing ideas from all earlier proposals. Reconstruction of the proto-paradigms necessarily requires also a reconstruction of the subsequent history of these inflections in the languages, & the most significant aspects of this will also be addressed. Not treated here, however, are the innovations peculiar to Blackfoot, the most divergent Algonquian language if not a sister language to all the rest collectively (Prouix 1980a:14; Goddard 1994a: 187-189).

While the central field appears well suited for tasks such as visual search, the periphery is optimized for rapid processing over broad regions. People vary in their abilities to make use of information in the center versus the periphery, and we propose that this bias leads to a trade-off between abilities for sequential search versus contemporaneous comparisons. The parameter of periphery-to-center ratio (PCR) describes the degree of peripheral bias, which evidence suggests is high in many people with dyslexia. That is, many dyslexics favor the peripheral visual field over the center, which results in not only search deficits but also (more surprisingly) talents for visual comparison. The PCR framework offers a coherent explanation for these seemingly contradictory observations of both deficit and talent in visual processing. The framework has potential implications for instructional support in visually intensive domains such as science and mathematics.

Protandric simultaneous hermaphroditism is known only from seven species of Lysmata, and it is not clear if this condition is fixed within the genus or if Lysmata includes species that are simply protandric or gonochoric (with separate sexes). This study uses anatomical data, aquarium experiments, and field observations to demonstrate that Lysmata nayaritensis is another protandric simultaneous hermaphrodite. It is shown that, despite occurring in the tropics, this species fits into the "crowd" species category, with high densities in the field and that the field sex ratio is highly male-biased. Information on the sex allocation and sexual system of more species needs to be examined before these observations can be put into a comparative context within the genus.

AN - 70750025; 17644982 AB - The science of cryobiology is essential to the effective, practical use of semen for assisted breeding to help manage small populations of rare wildlife species. In this review, we describe challenges associated with cryopreserving gametes from wild fauna. Based on more than 25 years of experience across a diversity of mammals, it appears that the primary driving force dictating cryo-survival of a spermatozoon is its initial pre-freeze quality and morphology, especially having a morphologically normal, intact acrosome. This assertion is supported through extensive studies of three animal groups that routinely ejaculate semen containing (1) normal sperm/acrosomal quality (examples, Eld's deer, Cervus eldi and giant panda, Ailuropoda melanoleuca), (2) normal acrosomal quality, but from teratospermic donors (>70% pleiomorphic sperm; cheetah, Acinonyx jubatus and black-footed ferret, Mustela nigripes) and (3) abnormal acrosomal quality and general teratospermia (clouded leopard, Neofelis nebulosa). Data revealed that species producing high quality sperm with > 70% normal, intact acrosomes were best able to survive cryopreservation (-80% intact acrosomes post-thaw). Species that were teratospermic, but with high proportions of intact acrosomes (72 to 88%) in ejaculates varied significantly (4 to 55% intact acrosomes post-thaw) in sperm survival to freeze-thawing. Spermatozoa from the clouded leopard (that was both teratospermic while producing only 11% normal acrosomes in fresh semen) failed to survive cryopreservation despite using an array of conventional and unconventional freezing approaches. These observations (combined with zona penetration assays and artificial insemination results) suggest that proportions of malformed sperm and especially initial structural integrity of the acrosome are more important predictors of sperm survivability post-thaw than initial sperm motility scores.

AN - 70669905; 17601413 AB - The endangered black-footed ferret (Mustela nigripes) has benefited from artificial insemination; however, improved sperm cryopreservation protocols are still needed. The present study focused on identifying factors influencing gamete survival during processing before cryopreservation, including: (1) the presence or absence of seminal plasma; (2) temperature (25 degrees C v. 37 degrees C); (3) type of medium (Ham's F10 medium v. TEST yolk buffer [TYB]); (4) cooling rate (slow, rapid and ultra-rapid); and (5) the presence or absence of glycerol. Seminal plasma did not compromise (P > 0.05) sperm motility or acrosomal integrity. Sperm motility traits were maintained longer (P 0.05) acrosomal integrity. Overall, TYB maintained optimal (P 0.05), indicating that 4% glycerol was non-toxic to ferret sperm; however, glycerol failed to ameliorate the detrimental effects of either rapid or ultra-rapid cooling. The results of the present study demonstrate that the damage observed to black-footed ferret spermatozoa is derived largely from the rate of cooling.

AN - 68953918; 17257524 AB - The objective was to examine the influence of animal age, season and captivity status on seminal quality in wild-born cheetahs (Acinonyx jubatus) in Namibia, Africa. Animals were divided into three age categories: juvenile (14-24 months; n = 16 males, 23 ejaculates); adult (25-120 months; n = 76 males, 172 ejaculates); and aged (>120 months; n = 5 males, 5 ejaculates). Seasons were categorised into hot-wet (January-April), cold-dry (May-August) and hot-dry (September-December). A comparison between freshly wild-caught (n = 29 males, 41 ejaculates) and captive-held cheetahs (n = 68 males, 159 ejaculates) was also conducted. Raw ejaculates contained 69.0 +/- 1.1% motile spermatozoa (mean +/- s.e.m.) with 73.6 +/- 1.5% of these cells containing an intact acrosome. Overall, 18.4 +/- 0.9% of spermatozoa were morphologically normal, with midpiece anomalies being the most prevalent (approximately 39%) defect. Juvenile cheetahs produced ejaculates with poorer sperm motility, forward progressive status, lower seminal volume and fewer total motile spermatozoa than adult and aged animals. Spermatogenesis continued unabated throughout the year and was minimally influenced by season. Proportions of sperm malformations were also not affected by season. Ejaculates from captive cheetahs had increased volume and intact acrosomes, but lower sperm density than wild-caught counterparts. In summary, Namibian cheetahs produce an extraordinarily high proportion of pleiomorphic spermatozoa regardless of age, season or living (captive versus free-ranging) status. Young males less than 2 years of age produce poorer ejaculate quality than adult and aged males. Because (1) all study animals were wild born and (2) there was little difference between freshly caught males and those maintained in captivity for protracted periods, our results affirm that teratospermia in the cheetah is mostly genetically derived. It also appears that an ex situ environment for the Namibian cheetah can ensure sperm quality comparable with that for free-living males.

AN - 68340238; 17767414 AB - We measured mosquito landing rates on adult and nestling American robins at nests with infrared cameras in Washington, D.C., and Maryland, United States. Mosquitoes landed on nesting robins almost exclusively between dusk and dawn. The mean number of mosquito landings per night was higher for adults (123.3 +/- SE 32.8) than nestlings (37.26 +/- 14.8). The fraction of mosquitoes landing at a nest on nestlings increased with decreases in adult brooding. Oral swabs from nestlings at these and 13 other robin, Gray catbird, and house finch nests were negative for West Nile virus (WNV). These results show that landing rates were higher on adults and that parental brooding reduces the landing rates of mosquitoes on nestlings. JF - Vector borne and zoonotic diseases (Larchmont, N.Y.)

AN - 57672243; 00494493 AB - Are the e-prints (electronic preprints) from the arXiv repository being used instead of journal articles? We show that the e-prints have not undermined the usage of journal papers from the four core journals in astrophysics. As soon as the journal article is published, the astronomical community prefers to read it and the use of e-prints through the NASA Astrophysics Data System drops to zero. This suggests that most astronomers have access to institutional subscriptions and that they choose to read the journal article. In other words, the e-prints have not undermined journal use in this community and thus currently do not pose a financial threat to publishers. Furthermore, we show that the half-life (the point at which the use of an article drops to half the use of a newly published article) for an e-print is shorter than for a journal paper.

The room-temperature (RT) sepiolite structure in air compares well with previous models but reveals an additional zeolitic H (sub 2) O site. The RT structure under vacuum retained only approximately 1/8 of the zeolitic H (sub 2) O and the volume decreased by 1.3%. Real-time, temperature-resolved synchrotron powder X-ray diffraction data and Rietveld refinements were used to investigate the behavior of the sepiolite structure from 300 to 925 K. Rietveld refinements revealed that most of the zeolitic H (sub 2) O is lost by approximately 390 K, accompanied by a decrease in the a and c unit-cell parameters. Above approximately 600 K the sepiolite structure folds as one-half of the crystallographically bound H (sub 2) O is lost. Rietveld refinements of the "anhydrous" sepiolite structure reveal that, in general, unit-cell parameters a and b and volume steadily decrease with increasing temperature; there is an obvious change in slope at approximately 820 K suggesting a phase transformation coinciding with the loss of the remaining bound H (sub 2) O molecule.

Sedimentological, geochemical, and paleontological changes across the boundary closely match patterns expected for a mass extinction caused by a single impact. A normally graded, approximately 2-cm-thick bed of spherules that is interpreted as a primary air-fall deposit of impact ejecta occurs between sediments of the highest Cretaceous Plummerita hantkeninoides foraminiferal zone and the lowest Paleogene P0 foraminiferal zone. There are no other spherule layers in the section. In addition to extinction of Cretaceous taxa, foraminiferal abundance drops from abundant to rare across the boundary. Ir concentrations reach a maximum of approximately 1.5 ppb at the top of the spherule bed, and the Ir anomaly is associated with enrichment in other siderophile elements. We attribute the unusually well-preserved and relatively simple stratigraphy to the fact that Demerara Rise was close enough ( approximately 4500 km) to the Chicxulub impact site to receive approximately 2 cm of ejecta, yet was far enough away (and perhaps sheltered by the curve of northern South America) to have been relatively unaffected by impact-induced waves.

Knowledge of community structure, the statistical distribution of the relative species abundance vector, makes possible comparisons and contrasts across time, space and/or environmental conditions. Our results indicate that species of Arctic foraminifera in age-correlated cores from abyssal depths are each best described by log-series distributions. Using this structural information, we were able to determine that structural stability exists for at least 50 ka. The foraminiferal communities in this study show remarkable concordance, distributional similarity and support the neutral theory of biodiversity.

By using the stable isotopic compositions of soil-formed minerals, fossil-plant matter, and shallow-water brachiopods, we estimated atmospheric partial pressure of carbon dioxide (pCO (sub 2) ) and tropical marine surface temperatures during this climate transition. Comparison to southern Gondwanan glacial records documents covariance between inferred shifts in pCO (sub 2) , temperature, and ice volume consistent with greenhouse gas forcing of climate. Major restructuring of paleotropical flora in western Euramerica occurred in step with climate and pCO (sub 2) shifts, illustrating the biotic impact associated with past CO (sub 2) -forced turnover to a permanent ice-free world.

Coal-ball and miospore floras from the Calhoun coal bed are dominated strongly by tree ferns, and pteridosperms and sigillarian lycopsids are subdominant, depending on geographic location within the coal bed. Although the overall composition of Calhoun peat-swamp assemblages is consistent both temporally and spatially, site-to-site differences and short-term shifts in species dominance indicate local topographic and hydrologic control on species composition within the broader context of the swamp. Statistical comparison of the Calhoun miospore assemblages with those from other Late Pennsylvanian coal beds suggests that the same basic species pool was represented in each peat-swamp landscape and that the relative patterns of dominance and diversity were persistent from site to site. Therefore, it appears that the relative patterns of proportional dominance stayed roughly the same from one coal bed to the next during Late Pennsylvanian glacially-driven climatic oscillations.

Oceanic localities are voluminous shield volcanoes on or near fossil-spreading ridges. Subaerial rocks of these volcanoes form either geochemically continuous and coherent rock series or bimodal suites. Low-pressure crystal fractionation of alkali basalt and assimilation of hydro-thermally altered rocks from the volcanic pile determined the compositions of the mafic-intermediate rocks at Socorro. Trachytes at Socorro were formed by partial melting of alkali basalt, and rhyolites through crystal fractionation of parental trachytes. These felsic rocks also assimilated hydrothermally altered rocks. Continental localities (late Oligocene to Quaternary) occur scattered north of the Trans-Mexican Volcanic Belt; their location is independent of older volcanic provinces and boundaries between today's geologic/tectonic provinces. Intraplate-type rocks have high TiO (sub 2) , Nb, and Ta contents, and host mantle and/or lower crust xenoliths+ or -megacrysts. Many fields are in the southern Basin and Range and the most extensive and voluminous were contemporaneous with normal faulting. The locations of some fields suggest that magma ascent was influenced by regional structures. However, normal faulting is minor or absent in many other Mexican fields. The petrogenetic processes in late Oligocene to Miocene magmas differ from those in Plio-Quaternary magmas. Slow ascent of magmas formed during early stages of extension-favored assimilation-fractional crystallization and gravitational settling of xenoliths. Plio-Quaternary xenolith-bearing magmas traveled faster through cooler crust where brittle structures caused by extension were able to propagate deeper. Geochemical evidence of assimilation is more subtle in the younger volcanic rocks.

The origin of the dichotomy, which may have set the course for most of the subsequent geologic evolution of Mars, remains unclear. Internally driven models for the dichotomy form the lowlands by mantle convection, plate tectonics, or early mantle overturn. Externally driven models invoke one giant impact or multiple impacts. Areal densities of buried basins, expressed by quasi-circular depressions and subsurface echoes in radar sounding data, suggest that the dichotomy formed early in the geologic evolution of Mars. Tectonic features along the dichotomy boundary suggest late-stage modification by flexure or relaxation of the highlands after volcanic resurfacing of the northern lowlands. Subsequent deposition and erosion by fluvial, aeolian, and glacial processes shaped the present-day dichotomy boundary.

The Cerrejon Formation outcrops in the Cerrejon Coal Mine, the largest open cast coal mine in the world. Two cores (725 m) were provided by Carbones del Cerrejon LLC for study. Two hundred samples were prepared for palynology, and at least 150 palynomorphs were counted per sample where possible. Several statistical techniques including rarefaction, species accumulation curves, detrended correspondence analysis, and Anosim were used to analyze the floristic composition and diversity of the palynofloras. Palynomorph assemblages indicate that the age of the Cerrejon Formation and the overlying Tabaco Formation is Middle to Late Paleocene (ca. 60-58 Ma). Major structural repetitions were not found in the Cerrejon Formation in the Cerrejon coal mine, and there is little floral variation throughout. The floral composition, diversity, and lithofacies do not change significantly. Lithofacies associations and floral composition indicate deposition fluctuating from an estuarine-influenced coastal plain at the base to a fluvial-influenced coastal plain at the top. There are, however, significant differences in the composition and diversity of coal and siliciclastic samples. Coal palynofloras have fewer morphospecies, and a distinct and more homogeneous floral assemblage compared to assemblages from the intervening sisliciclastic strata, suggesting that tropical swampy environments supported fewer plant species and had a distinct vegetation adapted to permanently wet environments.

Its similarity to Aksyiromys and other middle Eocene myomorphs from China and Central Asia suggests close relationships, which requires intercontinental interchange of these small rodents during the middle Eocene. At present, the biogeographic scenario for the origin and early evolution of Myomorpha that best fits the known record of occurrences is: evolution of Myomorpha from Sciuravidae in North America at least as early as the beginning of the middle Eocene, emigration of an Elymys-like myomorph from North America to Asia in the early middle Eocene, diversification of dipodoids and muroids in the later Eocene of Asia, emigration of Eucricetodon-like cricetids from Asia to North America (eumyine cricetids) in the latest Eocene, followed later by dipodids in the Miocene.

The new genus is distinguished from other paramyines in having the ectolophid on lower molars complete between protoconid and hypoconid and without a mesoconid, hypocone and metaconule on upper molars relatively larger than in Paramys, lower incisor wide with convex anterior surface, and masseteric scar on mandible more anterior than in other paramyines. The Uintan species Paramys compressidens Peterson is also assigned to Metaparamys. The Bridgerian P. delicatior Leidy appears to be a likely ancestor for Metaparamys based on the cross-sectional shape of the lower incisor. The occurrence of M. dawsonae is one of the latest records of a paramyine rodent in North America.

Calcareous nannofossil, planktonic foraminifera and palynomorph data from six wells in the Macuspana Basin, define chronostratigraphic intervals. Graphic correlation method and sequence stratigraphy allow the construction of a detailed chronostratigraphic framework. Subsurface sections in this basin represent deep to shallow marine environments which reveal basinward and landward facies shifts related mainly to sea level changes. Graphic correlation helps delineate stratigraphic sequences, while sequence stratigraphic key surfaces cause predictable patterns in the graphic correlation of biostratigraphic data. Integration of graphic correlation and sequence stratigraphy from the six wells reveals an erosional unconformity separating the Pliocene and Miocene strata.

In particular, the abundance, continuity of occurrence, and diversity of Metrarabdotos before its decline have made this genus, over the past 20 years, a model taxon for detailed morphometric studies of fine-scale evolutionary tempo and mode. During the same period, significant new occurrences of both Metrarabdotos and its near relatives have been documented with detailed collections from tropical American areas not represented in the original studies. In this paper we present a complete reanalysis of the original morphometric data (Cheetham, 1986a), incorporating the new tropical American material and comparative material of selected Metrarabdotos species from Europe and Africa in order to formalize the taxonomy of the genus, many species of which have been in open nomenclature since 1986, and to explore their possible phylogenetic relationships to each other and to Escharoides, Adeonellopsis, and Reptadeonella. The new analysis, with procedures slightly modified from those used in the original analysis, is based on more than twice the number of specimens and 20% more morphological characters. Although the results include changes in species assignments for 13% of the specimens in the original analysis, the pattern of intraspecific morphological stasis previously identified in the tropical American Neogene species, and thus the concomitant interpretation of evolutionary tempo and mode, are unaltered. Cladistic analysis resulted in a single most parsimonious tree for the 22 tropical American Metrarabdotos species, arranged in two monophyletic crown groups and a paraphyletic stem group. The stem group, ranging from latest Eocene to late Early or early Middle Miocene in age, includes four species, two of which are new: M. aguilerai from Venezuela and M. hispaniolae from the Dominican Republic and Haiti. Crown group A comprises seven species occurring in deposits of Late Miocene to Recent age, four of which are new: M. arawakarum from Venezuela; M. boldi and M. saundersi from the Dominican Republic; and M. coatesi, which occurs in the Dominican Republic, Costa Rica, and Panama. Crown group B, comprising 11 species, ranges from Early Miocene to Recent and includes five new species: M. cubaguaense from Venezuela; M. vokesorum from the Dominican Republic, Costa Rica, and Panama; and M. tainorum, M. jungi, and M. lopezense from the Dominican Republic. Incorporation of six European and African (eastern Atlantic) species, ranging in age from Early Miocene to Recent, into cladograms with the tropical American species produced more variable results in terms of both numbers of alternative trees and the positions of the tropical American species in them. One of these species. M. thomseni from the Pleistocene of Greece, and possibly a second, M. cf. M. maleckii Cheetham, 1968 from the Miocene of the Czech Republic, are new With one exception, the eastern Atlantic species were placed in more or less basal positions in one or the other of the crown groups, suggesting that, as hypothesized by Cheetham (1968), the "Old World" and "New World" species of Metrarabdotos represent largely independent radiations. The exception is the living species M. cookae Cheetham, 1968, from West Africa and the Cape Verde Islands, which is placed unequivocally in a terminal position in crown group B. Although the three groups of tropical American species correspond in part to subgenera of Metrarabdotos erected by Cheetham (1968), the paraphyly of the stem group and the unresolved identity of the type species of the subgenus apparently corresponding to crown group A suggest that formalizing the taxonomy of these groups is unwarranted at present. A further cladistic analysis, incorporating the three groups of Metrarabdotos species and Escharoides, Adeonellopsis, and Reptadeonella, yielded two trees, both of which support Cheetham's (1968) hypothesis that Metrarabdotos is more closely related to Escharoides than to Adeonellopsis and Reptadeonella. Escharoides is represented in tropical American Neogene deposits by two species, one of which, E. guraboensis from the Dominican Republic, is new. Of the six tropical American Neogene species of Adeonellopsis, four are new: A. cribrospiramen and A. guraboensis from the Dominican Republic. A. limonensis from Costa Rica, and A. antilleana from Cuba and Jamaica. Three of the six tropical American Neogene species of Reptadeonella, R. buddae from the Dominican Republic, R. collinsae from the Dominican Republic, Panama, Costa Rica. and the southeastern United States, and R. buricaensis from Panama. are also new.

His early researches were chiefly in marine zoology, which he continued to pursue throughout his career. However, in 1923 he began to work in the Sahara Desert and travelled through it for thousands of kilometres on foot and camel-back collecting samples for the museum and keeping detailed journals of the geology, palaeontology, flora, fauna, prehistoric artefacts, and the customs and cultures of the peoples he met. Monod published nearly 700 technical articles in scientific journals and numerous books for general readers. He won innumerable honours in France and internationally, but only one of his books, few of his articles, and no biographical accounts of Monod's activities have been published in English. This paper focuses on his search for the Fer de Dieu, an iron meteorite said to be 40 metres high and 100 metres long, lying in the desert of Mauritania. He found no trace of it, but the meteorite remains legendary in the history of meteoritics.

These boulders are olistoliths, derived from the edge of a nearby carbonate platform, long since eroded. Most of the olistoliths are reef limestones built of corals and calcareous sponges. At two levels, the reef fauna weathered out from the boulders and could be collected. Fourty-seven taxa of Scleractinia have been described and figured, which considerably extend our knowledge of the biodiversity of Cretaceous corals from the area.

Eclogites have major- and trace-element compositions of tholeiitic basalts with enriched mid-ocean ridge basalt (E-MORB) characteristics, whereas sedimentary gneiss resembles continent-derived shales. The geochemical data combined with field relations and Proterozoic protolith ages suggest the eclogite boudins formed as dikes or sills of basalt in sedimentary continental material of the East European platform during the initial opening of the paleo-Uralian ocean. Portions of the mafic boudins show large-ion lithophile-element (LILE) and light-rare-earth element (LREE) enrichment. Fluid transport of the LILE and LREE in the subduction zone seems to have been channelized (or otherwise spatially organized) on a scale of meters, rather than resulting from pervasive fluid flow. The metasomatizing fluids were most likely dehydration fluids produced during prograde metamorphism of sediments or K-altered basalts that were preserved through peak metamorphism and may have transported additional elements during retrograde metasomatism.

The potters and workers left scant records that reveal how their wares fit into Utah's theocratically organized economy. Potters and potteries of 19th-century Utah and the Mormon Domain were part of an archaeological survey conducted between 1999 and 2000. The research project yielded examples of kiln wasters that could be subjected to instrumental neutron activation analysis (INAA). The results demonstrate the utility of integrating primary records and archaeometric tools in the study of historical era economic processes. Data also indicate the applicability of the approach for potteries in close geographic proximity and to determine patterns of variation within site assemblages.

The only western Atlantic species, A. nuttingi, occurs from the southeastern United States to Brazil. The two eastern Pacific species are A. galapagensis Sivertsen, 1933 (synonyms: A. canalis Kim & Abele, 1988; A. cryptodentatus Christoffersen & Ramos, 1988), which occurs from the Gulf of California to Colombia and Galapagos, and A. millsae, n. sp., presently known only from a few localities in Panama. The three species differ morphologically, genetically, and in color pattern. The two eastern Pacific species both can be found in the intertidal, but A. millsae, n. sp. occurs slightly deeper, suggesting the possibility of ecological speciation. All evidence shows that A. nuttingi and A. millsae, n. sp. are transisthmian sister species, with A. galapagensis forming their sister clade. Genetic differentiation between the transisthmian sister species suggests a divergence time of approximately 6 mya, well before the final closure of the Isthmus of Panama.

We manipulated the presence/absence of an Fe(II)-oxidizing bacterium (Sideroxydans paludicola, strain BrT) in axenic hydroponic microcosms containing the roots of intact Juncus effusus (soft rush) plants to determine if FeOB affected total rates of rhizosphere Fe(II) oxidation and Fe plaque accumulation. Our experimental data highlight the importance of both FeOB and plants in influencing short-term rates of rhizosphere Fe oxidation. Over time scales ca. 1 wk, the FeOB increased Fe(II) oxidation rates by 1.3 to 1.7 times relative to FeOB-free microcosms. Across multiple experimental trials, Fe(II) oxidation rates were significantly correlated with root biomass, reflecting the importance of radial O2 loss in supporting rhizosphere Fe(II) oxidation. Rates of root Fe(III) plaque accumulation (time scales: 3 to 6 wk) were ~ 70 to 83% lower than expected based on the short-term Fe(II) oxidation rates and were unaffected by the presence/absence of FeOB. Decreasing rates of Fe(II) oxidation and Fe(III) plaque accumulation with increasing time scales indicate changes in rates of Fe(II) diffusion and radial O2 loss, shifts in the location of Fe oxide accumulation, or temporal changes in the microbial community within the microcosms. The microcosms used herein replicated many of the environmental characteristics of wetland systems and allowed us to demonstrate that FeOB can stimulate rates of Fe(II) oxidation in the wetland rhizosphere, a finding that has implications for the biogeochemical cycling of carbon, metals, and nutrients in wetland ecosystems.

Historic collecting records document the past presence of this subspecies at multiple sites in New Jersey and Long Island, while single specimens are also known from Delaware, Maryland, and Pennsylvania. This tiger beetle apparently has been extirpated from much of its former range, and extant populations are known only from sites within state forests and state wildlife management areas in the Pine Barrens region of New Jersey. Soil, vegetation, and forest stand characteristics were studied at four sites occupied by populations of C. p. consentanea in 2004, 2005, and 2006. Observations on adult biology and population dynamics are reported. Adult beetles were active along sandy trails and firebreaks in pine-oak woodlands dominated by Pinus rigida Miller (Pinaceae) and several Quercus species (Fagaceae), primarily Quercus ilicifolia Wangenheim. The use of prescribed fire as a forest management tool was evident at three of the four sites. Management activities which may benefit these populations include the continuation of prescribed burns as well as routine trail and firebreak maintenance.

Much of this work has focused on understanding whether rising temperatures on temperate breeding grounds are advancing migration phenology and limiting reproductive success. However, conditions on tropical nonbreeding quarters can also shape these processes, yet few studies have directly measured bird responses to climate during this part of the annual cycle. We tested the hypothesis that variation in winter rainfall can influence food availability and the nonbreeding season performance of American redstarts Setophaga ruticilla occupying 2 contrasting habitats: wet, mangrove forest and dry, second-growth scrub. From 2002 to 2005, food availability, body mass, and spring departure schedules of birds in both habitats were highly dependent on rainfall. Food availability in mangrove forest was higher than in second- growth scrub in 3 out of 4 yr, allowing birds in this habitat to maintain better physical condition through the winter and depart earlier on spring migration. However, abundant rainfall in the spring of 2004 led to abnormally high food availability in scrub and early departure of birds in both habitats. These results suggest that rainfall on tropical wintering areas can have major effects on the nonbreeding season performance of migratory birds, and that the timing of rainfall within the dry season, not just the absolute amount, may be critical for orchestrating migratory departure schedules. Because rainfall in tropical regions is projected to decline drastically over the next 50 yr, migratory birds could face increasingly severe food shortages prior to spring migration. Such conditions could force departure schedules to become delayed and constrain adaptation to selection for earlier breeding in response to rising temperatures at breeding areas.

We use mtDNA sequence data to examine patterns of genetic variation, sequence divergence and phylogenetic relationships between phenotypically distinct groups of the yellow-rumped warbler complex. Currently classified as a single species, the complex is composed of two North American migratory forms (myrtle warbler Dendroica coronata coronata and Audubon's warbler Dendroica coronata auduboni), and two largely sedentary forms: Dendroica coronata nigrifrons of Mexico, and Dendroica coronata goldmani of Guatemala. The latter are typically considered to be races of the Audubon's warbler based on plumage characteristics. However, mtDNA sequence data reveal that sedentary Mesoamerican forms are reciprocally monophyletic to each other and to migratory forms, from which they show a long history of isolation. In contrast, migratory myrtle and Audubon's warblers form a single cluster due to high levels of shared ancestral polymorphism as evidenced by widespread sharing of mtDNA haplotypes despite marked phenotypic differentiation. Sedentary and migratory forms diverged in the early Pleistocene, whereas phenotypic differentiation between the two migratory forms has occurred in the Holocene and is likely the result of geographical isolation and subsequent range expansion since the last glaciation. Our results underscore the importance of Quaternary climatic events in driving songbird speciation and indicate that plumage traits can evolve remarkably fast, thus rendering them potentially misleading for inferring systematic relationships.

In addition, tissue nitrogen concentration ([N]) often fails to keep pace with enhanced carbon gain under elevated CO2, particularly in C3 species. While these responses are well documented in many species, implications for plant growth and nutrient cycling in native ecosystems are not clear. Here we present data on 18 years of measurement of above and belowground biomass, tissue [N] and total standing crop of N for a Scirpus olneyi-dominated (C3 sedge) community, a Spartina patens-dominated (C4 grass) community and a C3-C4-mixed species community exposed to ambient and elevated (ambient +340ppm) atmospheric [CO2] in natural salinity and sea level conditions of a Chesapeake Bay wetland. Increased biomass production (shoots plus roots) under elevated [CO2] in the S. olneyi-dominated community was sustained throughout the study, averaging approximately 35%, while no significant effect of elevated [CO2] was found for total biomass in the C4-dominated community. We found a significant decline in C4 biomass (correlated with rising sea level) and a concomitant increase in C3 biomass in the mixed community. This shift from C4 to C3 was accelerated by the elevated [CO2] treatment. The elevated [CO2] stimulation of total biomass accumulation was greatest during rainy, low salinity years: the average increase above the ambient treatment during the three wettest years (1994, 1996, 2003) was 2.9tha-1 but in the three driest years (1995, 1999, 2002), it was 1.2tha-1. Elevated [CO2] depressed tissue [N] in both species, but especially in the S. olneyi where the relative depression was positively correlated with salinity and negatively related with the relative enhancement of total biomass production. Thus, the greatest amount of carbon was added to the S. olneyi-dominated community during years when shoot [N] was reduced the most, suggesting that the availability of N was not the most or even the main limitation to elevated [CO2] stimulation of carbon accumulation in this ecosystem.

Atmospheric CO sub(2) variations generally follow changes in temperature and other climatic variables rather than preceding them. Likewise, there is no confirmation of the often-posited significant supporting role of methane (CH sub(4)) forcing, which--despite its faster atmospheric response time--is simply too small, amounting to less than 0.2 W/m super(2) from a change of 400 ppb. We cannot quantitatively validate the numerous qualitative suggestions that the CO sub(2) and CH sub(4) forcings that occurred in response to Milankovic orbital cycles accounted for more than half of the amplitude of the changes in the glacial/interglacial cycles of global temperature, sea level, and ice volume. Consequently, we infer that natural climatic variability-- notably the persistence of insolation forcing at key seasons and geographical locations, taken with closely related thermal, hydrological, and cryospheric changes (such as the water vapor, cloud, and ice albedo feedbacks)-- suffices in se to explain the proxyderived, global and regional climatic and environmental phase-transitions in the paleoclimate. If so, it may be appropriate to place anthropogenic greenhouse gas emissions in context by separating their medium-term climatic impacts from those of a host of natural forcings and feedbacks that may, as in paleoclimatological times, prove equally significant.

Several experiments in shaded coffee farms have explored how insectivorous birds reduce herbivore numbers and their damage to plants and have simultaneously approached ecological questions that are applied (e.g. biological control) and basic (e.g. Tri-trophic interactions) (Borkhataria et al. 2006, Greenberg et al., Perfecto et al. 2004). Here we used exclosures to test whether birds lower the densities of herbivorous insects and reduce insect damage to cocoa (Theobroma cacao L., Sterculiaceae) foliage in shaded farms of western Panama. Although bird predation has been shown to reduce insect damage to crops in other systems (Mols & Visser 2002), we provide the first test for shade-grown cocoa.

It has been proposed that a small hook-shaped cape, now submerged, was present off the site during settlement from about 700 to 389 BC. Since 1992, however, most of Kaulonia's seafloor sector has been buried by a thick (to 4 m) sand cover. This investigation resumes study of Kaulonia's margin by high-resolution seismic survey, analysis of sediment in cores and excavated sections buried along the coast, and petrologic examination of rock used for construction of a temple, the site's major structure. The sector, located in the tectonically active Calabrian arc, has been subject to considerable elevation rise of land onshore, and an equivalent rate of seafloor subsidence ( similar to 1 mm/yr). A distinct Holocene sequence, composed of beachrock-type sandstone and fluvial-marine-transported conglomerate, in sediment sections landward of the beach can be traced seaward to depths of similar to 7 m about 300 m from the present shoreline. Correlation of the sequence helps define changes of coastline position from before Greek settlement to the present. Rather than a generally progressive migration landward of the shoreline in response to relative sea-level rise, the coast has experienced more complex shifts (sea-to-land, land-to-sea, and return to land) due to up-and-down motion in the sector between the alluvial plain behind the beach and innermost shelf. By the mid-Holocene, the shoreline had advanced seaward, resulting in coastal emergence, and it did not return landward (resubmerging the margin) until after the site's abandonment; submergence was complete by late Roman time. We now recognize a broad arcuate headland, rather than a small hooked cape, seaward of the site similar to 2500 years ago. Without a lagoon, sufficiently deep lake, or man-made port available for protected anchorage, vessels sailing to Kaulonia for trade were either beached or anchored close to shore and, perhaps seasonally, within the mouth of the Assi River. Composition of beachrock-type sandstone in Holocene sections on land is comparable to that offshore and also to sandstone used for temple base construction. Extensive sandstone exposures along this coast may have been one reason why Greeks selected the site for settlement.

However, less is known of such variation among tree species within the C sub(3) group. Here we measured the TE sub(C) of seven C sub(3) tropical tree species. Isotopic analyses ( delta super(13)C, delta super(18)O, and delta super(15)N) and elemental analyses (carbon and nitrogen) were undertaken to provide insight into sources of variation in TE sub(C). Plants were grown over several months in approx. 80% full sunlight in individual 38-l containers in the Republic of Panama. Soil moisture content was nonlimiting. Significant variation was observed in TE sub(C) among the C sub(3) tree species. Values ranged from 1.6 mmol C mol super(-1) H sub(2)O for teak (Tectona grandis) to 4.0 mmol C mol super(-1) H sub(2)O for a legume, Platymiscium pinnatum. Variation in TE sub(C) was correlated with both leaf N concentration, a proxy for photosynthetic capacity, and oxygen-isotope enrichment, a proxy for stomatal conductance. The TE sub(C) varied with C-isotope discrimination within species, but the relationship broke down among species, reflecting the existence of species-specific offsets.

AN - 19561485; 7227604 AB - Aim: To assess whether the total richness of the shore-fish fauna of a discrete biogeographical region can be predicted, and to estimate how long it is likely to take to enumerate that fauna. Location: The Tropical Eastern Pacific (TEP), an isolated biogeographical region with a high level of endemism (72%) among its modestly rich, known fauna of shore fishes (1222 named + 58 known undescribed shallow-water species). Methods: We used patterns in the long-term dynamics and accumulation curves of descriptions of new species, which began in 1758, correlates of these patterns, and the body size-frequency distributions of various ecological groups of the fauna to (1) try to predict the total richness of that fauna, (2) estimate how many species might be missing and what biological characteristics they might have, and (3) estimate how long their discovery and description will take to complete. Results: Accumulation curves for the entire fauna, for all TEP endemics or for reef and soft-bottom species (77.5% of the fauna) are not approaching asymptotes, and their description rates have remained fairly stable over the past century. However, curves for pelagic and multi-habitat species (22.5% of the fauna) may be nearing asymptotes, perhaps because these species are relatively accessible to collection. These curves clearly indicate that the total TEP fauna is substantially richer than the presently known fauna, but do not allow reliable prediction of its richness. Extrapolations from frequency distributions of the body size of different ecological groups of TEP fishes indicate that the entire fauna is at least 12-15% larger than the currently known fauna. Main conclusions: From recent description trends, undiscovered species will tend to be small, have limited geographic and depth ranges, and live in deeper water. Poorly known, priority areas for taxonomic investigation in the TEP include deeper reef habitats, two isolated island groups, and several continental areas with unusual environments. At current levels of traditional taxonomic activity, the description of known unnamed species will take c.15 years, and assessment of the richness of unknown species, which probably number in the hundreds, will take decades.

Studies have shown that environmental enrichment can promote natural parental behaviors in zoo animals. The objective of this study was to determine the effects of environmental enrichment on behavioral and physiological responses of maned wolves. During an 8-week experimental period, daily behavior observations and fecal sample collection were conducted on four adult wolves (2.2) individually housed in environments without enrichment. After 2 weeks, the wolves were chronologically provided with 2-week intervals of hiding dead mice around the exhibit, no enrichment, and introduction of boomer balls. Responses of the wolves to enrichment were assessed based on activity levels and exploratory rates, as well as the level of corticoid metabolites in fecal samples collected daily throughout the study period. Providing wolves with environmental enrichment significantly increased exploratory behaviors (P<0.05), especially when mice were hidden in the enclosure. Fecal corticoid concentrations were increased during periods of enrichment in males (P<0.05), but not in females. Overall, there were no correlations between behavioral responses to enrichment and fecal corticoid levels. Behavioral results suggest that environmental enrichment elicits positive effects on the behavior of captive maned wolves. There is evidence suggesting that providing animals with ability to forage for food is a more effective enrichment strategy than introducing objects. There is need for a longer term study to determine the impact of environmental enrichment in this species. Zoo Biol 26:331-343, 2007.

These vocal differences are as great or greater than vocal differences documented between syntopic species-pairs in the family Thamnophilidae (Isler et al. 1998). Evidence is also provided that two forms currently considered subspecies are syntopic and that two others are parapatric without apparent physical barriers. Vocally, the pair of syntopic taxa were distinguished dramatically, but solely, by common calls. The finding that common calls were as diversified as songs in this species-group suggests that calls may be as important as songs in reproductive isolation. Future field studies should therefore focus on clarifying the function of different types of thamnophilid vocalizations and elucidating their role in speciation. This is the first contribution to a multifaceted analysis of the vocalizations and genetic structure of typical antbirds (Thamnophilidae) in Amazonia. In future work, results of the vocal analysis will be compared with a parallel genetic study, after which the two analyses will be integrated to suggest a phylogeny. The present study and preliminary studies of genetic differentiation (e.g., Bates et al. 1999) make it clear that the H. cantator complex has had a long evolutionary history that produced greater species-level diversity than was recognized previously.

Maintaining diversity of trees in forestation enhances the conservation of trees and other organisms, decreases production risks and increases the possibility of natural regeneration. The value of forest products may be increased or decreased, but increasing diversity always complicates forest management. Species diversity could be increased by encouraging forest owners and managers to mix species; in order to achieve this, scientific information on lesser-known species and silviculture of mixtures must be compiled and disseminated.

The Laetoli vertebrate fossil fauna is also of great interest because its taxonomic composition, especially in the family Bovidae, differs from that of other East African faunas of comparable age. However, the taphonomic history and paleoecological context of the Upper Laetolil fossil faunal assemblage is not fully understood. Furthermore, the depositional environment of the Upper Laetolil Beds was initially associated with a dry, savanna-like environment characterized by grassland, shrubs, and isolated trees. However, revised stratigraphy and taphonomy at Localities 8 and 9 indicate an existence of more complex depositional environments than those previously described. Fossil faunal remains from the Upper Laetolil Beds are represented by highly variable numbers of skeletal parts dominated by heavily fractured and/or modified distal, proximal, and midshaft fragments of varying sizes, and many isolated teeth. Unlike marine fossil deposits, which furnish thick sections with rich fossil accumulations of invertebrates, the Laetoli deposits are most commonly composed of low-density accumulations with terrestrial faunal assemblages that differ significantly from modern counterparts. Observed changes in faunal composition at Laetoli especially between the Lower and Upper Units, have been noted, but their cause has not been established. We present a detailed taphonomic and stratigraphic analysis of fossil faunal assemblages from the Upper Laetolil Beds at Localities 8 and 9 in northern Tanzania.

The influence of environment on evolutionary change can be stated as a series of hypotheses. Adaptation hypotheses include the following: novel adaptations emerged in hominins and contemporaneous mammals (1) within relatively stable habitats; (2) during progressive shifts from one habitat type to another; and (3) due to significant rises in environmental variability. These ideas further suggest the "adaptability hypothesis": (4) since adaptations potentially evolved in environmentally stable, progressively changing, or highly variable periods, lineages have differed in their ability to endure environmental fluctuation. Thus, extinction of certain adaptations (and lineages) should have corresponded with heightened environmental variability, while new adaptations evolved during those periods should have enabled a lineage to persist (and spread) through a novel range of habitats. Turnover hypotheses, on the other hand, concern the timing and processes of species origination and extinction in multiple clades. These hypotheses state that species turnover; (5) was concentrated in a narrow interval of time related to a major climate shift; (6) spanned several hundred thousand years of climate change, and occurred in a predictable manner dependent on the nature of species adaptations; and (7) took place gradually over a long period as lineages originated, persisted, or went extinct within a changing mosaic of habitats. A separate, biogeographic hypothesis regarding faunal change posits that; (8) substantial climatic and tectonic disruptions resulted in multiple episodes of faunal community formation (assembly) and breakup (disassembly). This assembly-disassembly process may have had profound effects on Pliocene and Pleistocene faunas of Africa and on researchers' ability to infer significant events of faunal evolution from fossil sequences at the basin or sub-basin scale. Since all ideas about environmental effects on evolution depend on temporal correlation, an important challenge is to match faunal sampling to the precessional ( approximately 20 Kyr) and obliquity (41 Kyr) scale of Pliocene climate dynamics.

Apart from Hadar, it has yielded the largest sample of specimens attributable to the mid-Pliocene hominin, Australopithecus afarensis, including the type specimen. As such, it is important to explore the paleoenvironment at Laetoli, especially the different habitat types that may have been exploited by A. afarensis. Previous interpretations of the paleoecology at Laetoli have led to quite different conclusions. Initially, the paleoenvironment was reconstructed as an arid to semi-arid grassland with scattered bush and tree cover, and patches of acacia woodland, similar to the modern-day local setting. However, some aspects of the fauna do indicate that the range of habitats may have included more dense bush cover and more extensive tracts of woodland than seen in the region today. The main objective of this paper is to re-examine this issue by more thoroughly documenting the paleoecological setting by conducting a more detailed and comprehensive comparative analysis of the mammalian fauna. To this end, the ecovariable structure of the mammalian fauna at Laetoli is compared to other Plio-Pleistocene hominin-bearing fossil localities and modern faunal communities from different habitats, including forest, woodland, open woodland, bushland, shrubland, grassland, and desert. Principal components analysis (PCA) and bivariate analyses of predictor ecovariables were conducted. An important finding was the general distinctiveness of fossil assemblages, including Laetoli, from modern communities. Terrestrial mammals were found to have the greatest impact on the uniqueness of fossil communities, with fossil assemblages having very high proportions of terrestrial mammals when compared to modern communities. Furthermore, the high frequency of grazers and terrestrial mammals, combined with the low occurrence of arboreal and frugivorous mammals at Laetoli, indicates affinities with modern mammalian communities living in grassland, savanna, and open woodland settings. Taking into account the results of this study, and the presence of indicator species, we reconstruct the paleoecology of the Upper Laetolil Beds as a mosaic habitat dominated by grassland and shrubland, with areas of open- to medium-cover woodlands, as well as some closed woodland and possibly gallery forest along seasonal river courses.

This chapter examines modern owl-accumulated micromammal assemblages from Serengeti, Tanzania. These modern roost data are used to examine the fidelity of the taxonomic signal and its sensitivity to change across habitats within an ecosystem. The modern data show that the relative abundance of prey taxa in owl-accumulated assemblages varies across habitats in a predictable fashion. This provides a basis for applying the analysis of fossil micromammal assemblages to intrabasin scales using relative abundance as well as biome or regional scales using presence/absence of taxa. Using the modern micromammal assemblages as analogues, the latter part of the chapter explores taphonomic and paleoenvironmental change through Bed I times at Olduvai Gorge.

The foundation for all such paleoecological interpretations consists of fossil specimens in their original geological context. Study of fossils in context generates a body of "first-order" evidence consisting of taxonomic identifications of specimens and placement of these taxa in a time/space continuum. Analysis of first-order faunal data in light of additional evidence about taphonomy, sedimentology, geochemistry, and ecomorphology generates a body of "second-order" interpretations. These require additional assumptions and result in evidence for the ecological attributes of a taxon, its habitat, and its temporal and spatial relationships to other taxa. Both first- and second-order data sets can be examined for larger-scale patterns across space and through time. The validity of inferences relating faunal evidence to the ecology of a hominin species requires an additional step, i.e., careful consideration of exactly how the faunal information relates spatially and temporally to hominin remains and archeological sites. Examples of different approaches to using faunal information to infer paleoenvironmental contexts, paleoecological relationships, and long-term ecological trends highlight major issues in faunal analysis and how these relate to understanding the ecological context of human evolution.

To address the question of which taxa were most likely to have had competitive interactions with hominins, modern carnivorans were sorted into size classes based on shifts in behavior, ecology, and body mass. Four size classes were created, among which the two largest (21.5-100 kg and > 100 kg) include those taxa whose behavior is most relevant to the evolution of hominin dietary behavior. Fossil taxa were then assigned to these size classes. A summary of the temporal range and reconstructed behavior and ecology of fossil members of the two largest size classes is presented. We discuss the relevance of each taxon to reconstructing hominin behavior and suggest that hominins must have evolved not only successful anti-predator strategies, but also successful strategies to avoid kleptoparasitism before carcass-based resources could become an important part of the diet. Although hominins were unlikely to have been top predators upon first entrance into the carnivore guild, effective anti-predator/anti-kleptoparasitism strategies in combination with the eventual evolution of active hunting would have increased the rank of hominin species within the guild. While the appearance of stone tools at 2.6 Ma has no apparent effect upon carnivorans, the appearance of Homo ergaster after 1.8 Ma may have been at least partly responsible for the decrease in the carnivoran origination rate and the increase in the extinction rate at this time. The behavior of H. ergaster, climate change, and concomitant changes in prey species richness may have caused carnivoran species richness to drop precipitously after 1.5 Ma. In this situation, even effective kleptoparasitism by H. ergaster may have been enough to drive local populations of carnivorans that overlapped with hominins in dietary resources to extinction. Possibly as a result, the modern guild, which evolved within the last few hundred thousand years, is composed primarily of generalists. Although the impact of H. sapiens on the carnivoran guild cannot be assessed due to a lack of carnivoran fossils from this time period, one might not consider the modern carnivore guild to be complete until the appearance of our species approximately 200,000 years ago.

The faunal diversity resembles an African shortgrass plains assemblage. The taxonomic diversity is nevertheless low, emphasizing an incomplete fossil record. Based on modern bovid representation in African game parks, statistical tests show that the Chiwondo bovid assemblage consists of a mixture of species found in the Somali-Masai and the Zambezian ecozones. The composition of the terrestrial fauna is similar to Swartkrans 1 and the Upper Ndolanya Beds. The fossil assemblages can be assigned to three biostratigraphic time intervals that date from older than 4.0 Ma to less than 1.5 Ma. The occurrence of Paranthropus boisei at a lake margin site in the Chiwondo Beds corresponds to robust australopithecine-bearing localities near Lake Turkana, Kenya. A case study showed that the investigated death assemblage on a delta plain in the Malema region was subject to heavy modification after deposition. This has affected the size distribution, the frequencies of skeletal elements, and thus the taxonomic composition. High-density skeletal elements such as molars and partial mandibles dominate the assemblage. The Homo rudolfensis locality at Uraha has a different faunal composition, the preservation in a paleosol points to a different taphonomic history and the Uraha area encompasses a longer time span.

Some of these differences were caused by well-documented differences in geography and geology of the formation and the history of the research efforts of the two expeditions. Other differences apparently arose because of factors that are less well documented. The following paper briefly describes the well-documented factors leading to differences in specimen counts, including differences in the sizes of areas explored, months of active fieldwork, and numbers of sites excavated for the recovery of macro- and microfaunal remains. Further, it proposes methods for discovering factors that are less well documented, likely related to differences in research strategies and the inherent richness of the sediments explored. And finally, it suggests how the collections might be best used to avoid the effects of biases that they apparently contain.

The 2004 Workshop on Faunal Evidence for Hominin Paleoecology at the Smithsonian Institution focused on the second of these research themes, bringing together a multi-national group of 44 professionals and students for in-depth discussion about how the East African mammalian faunal record can be used to reconstruct the changing paleoecological context of the hominins during their time of major diversification from late Miocene to early Pleistocene. Many of the contributions to this volume originated as papers presented at a 2003 American Association of Physical Anthropologists symposium in Tempe, Arizona, organized by Bobe, Alemseged, and Behrensmeyer. These contributions evolved as a consequence of the discussions at the Smithsonian workshop, taking on broader issues and adapting to a wide range of ideas and concerns expressed by the participants.

This theory posits that changes in global climate cause "turnover pulses", within relatively short periods of time during which occur large numbers of first and last appearances of species. The present study examines whether a turnover pulse, or other forms of faunal change, occurred in the Cercopithecidae, 2.8-2.5 Ma at a time of major global cooling. The East African cercopithecid fossil record is well suited to this analysis because cercopithecids occur at most East African Pliocene and Pleistocene sites and are relatively speciose (Szalay and Delson, 1979; Delson, 1984; Jablonski, 2002). Several approaches are used including examination of cercopithecid species ranges as well as the abundance of larger taxonomic units. Both appearance and abundance data are examined for the Afar Depression and Turkana Basin, whereas only the species range data are studied for all East African and complete sub-Saharan analyses. The results provide no support for a turnover pulse 2.8-2.5 Ma. In fact, the largest number of first and last appearances are clustered around 3.4 and 2.0 Ma, with a shift in abundance at 3.4 Ma in both samples examined. These results are consistent with a relatively constant rate of turnover of cercopithecids between about 4 Ma and the Holocene.

Paleontological databases from the Turkana Basin of Kenya and Ethiopia (East Turkana, West Turkana, Kanapoi, Lothagam, and Omo) and the Hadar Basin of Ethiopia's Afar region consist of nearly 70,000 specimens of fossil vertebrates (mostly mammals) that date from the late Miocene to the Pleistocene. Here we focus on the most abundant family of fossil mammals, the Bovidae (N = 8213 specimens), and illustrate patterns of taxonomic abundance and diversity from about 7 Ma (million years ago) to about 1 Ma. The key questions we address are the following: How much variation in patterns of faunal change is there within different areas of a large sedimentary basin? How much variation is there between basins? How are these patterns related to broad signals of climatic change? What are the implications of the bovids for East African environments and for hominin evolution in the late Cenozoic? A correspondence analysis of bovid tribes indicates that important differences in taxonomic abundance existed among different areas of the Turkana Basin, and that some of these differences had environmental implications. The lower Omo Valley appears to have remained distinct from other parts of the Turkana Basin between 3 and 2 Ma, with consistently higher proportions of Tragelaphini and Aepycerotini, and at times of Reduncini and Bovini. These bovids are indicative of woodlands or forests (Aepycerotini and Tragelaphini) or of moist grasslands near wooded habitats (Reduncini and Bovini). An analysis of bovid tribes indicative of open and seasonally arid grasslands (Alcelaphini, Antilopini, and Hippotragini) shows relatively high proportions of these bovids in the West Turkana areas, but very low proportions in the Omo, especially prior to about 2 Ma. This indicates that the Omo remained wetter and more wooded than other parts of the Turkana Basin for much of the Plio-Pleistocene, while the West Turkana area appears to have been more open than other parts of the basin, and East Turkana had conditions intermediate between those at West Turkana and those in the Omo. Fossil bovids from the Hadar Basin suggest diverse environments including woodlands, wet grasslands, and drier savanna grasslands. An increase in the abundance of arid adapted bovids in the late Pliocene and early Pleistocene of the Turkana and Hadar Basins provides evidence that faunal changes in these different areas were driven by common factors consistent with the known record of climatic change. Analyses of species diversity among bovids show three peaks of richness in the Pliocene and Pleistocene. The first peak occurred at about 3.8-3.4 Ma, the second at 2.8-2.4 Ma, and the last from about 2.0 to 1.4 Ma. The last two of these peaks coincide with previously identified periods of high faunal turnover in East Africa. Although climate appears to have shaped major patterns in the evolution of bovids, the fact that different areas of a single sedimentary basin show distinct responses highlights the complexities involved in establishing causal links between paleoclimate and evolution.

Over the past three decades substantial progress has been made due to the proliferation of fieldwork and a consequently expanding fossil record, and development of new methods of analysis. The present study uses data of fossil mammals from the Shungura Formation of Ethiopia, with specimens collected semi-independently by French and American research teams who worked in the southern and northern parts of the Shungura area respectively. We compare these two samples in terms of collection methods, taxonomy, taphonomy, and local environmental differences. The following results were obtained: (1) No major taphonomic differences were observed between the two collections. The effect of a major taphonomic shift that occurred in the middle of Member G (G-13) is observed in both samples and is caused by the important change in the depositional environment from fluvial to lacustrine conditions. (2) The French team collected more specimens than the American team, in part because it had a larger area of exposures, and it spent two extra seasons in the field. Additionally, the French team collected more large-sized taxa including their postcranial elements, while the American team recovered a restricted set of postcranial bones. In contrast, the American team collected more primates and carnivores than the French team. (3) Despite these differences, comparable taxonomic composition and number of species are observed in both collections. (4) A study of changes in relative abundance in bovid tribes indicates that similar patterns of variation through time are observed in both samples. This is considered to be evidence for the prevalence of generally similar habitats (and habitat change through time) in the north and south of the Shungura area. (5) However, habitat differences may have occurred locally, as inferred by differences in taxonomic abundances at the species level. For example, the bovid Menelikia lyrocera was more common in the southern parts of the Shungura exposures, while Kobus sigmoidalis was more common in the north. (6) Finally, the present study underscores the importance of the quality of data in unraveling past environments and patterns of faunal changes through time. Well-controlled and standardized collecting methods and systematic documentation procedures are critical for future fieldwork activities. This will improve the quality of our data, facilitate comparisons across regions, and lead to more robust hypotheses.

This helps to clarify the extent of variation in the same species from different sites. The analyses suggest that species transitions occurred in several lineages at about 2.7-2.8 Ma and, less clearly, around 1.6-1.8 Ma. Increasing hypsodonty is compatible with increasing amounts of harsh diet. Whether or not these changes are triggered by some external factors needs further investigation.

With only two exceptions, the natural colour diamonds could be separated into three categories (on the basis of the peak wavelength and the fluorescence spectra) that generally corresponded with their body colours: 1) approximately 450 and approximately 490 nm recorded mainly for pink, yellow and fancy white diamonds, 2) approximately 525 nm mainly for green-yellow or yellow-green and brown diamonds and 3) approximately 550 nm mainly for orange, grey-green (including chameleon) and type Ia blue-grey or grey-blue diamonds. A spectrum that is anomalous for the diamond's body colour may indicate that it has been treated; in some cases, fluorescence spectroscopy can help to determine diamond type.

The areal density of QCDs indicates that the N lowland crust is similar in age to that of the exposed southern highlands, but younger than the highlands basement which hosts the QCDs. Other results from the MARSIS instrument are summarized. Much of the smooth plains of the N lowlands consists of late Hesperian and early Amazonian surficial deposits of the Vastitas Borealis formation which partly bury wrinkle ridges. Evidence of olivine-rich deposits associated with fresh impact craters in the lowlands, indicate that the ridged plains beneath Vastitas Borealis formation sediments are volcanic. The age of the northern lowland crust is critical in determining when and how the hemispherical dichotomy formed. The northern lowland crust is geologically ancient and with the QCD-based crater density age, indicates that this dichtomy formed in the early Noachian and is at least as old as that of exposed highland crust.

A considerable proportion of the extractable phosphorus occurred in organic forms (19-44%), mostly as phosphate monoesters, with smaller concentrations of DNA. Inositol phosphates were detected in less than half of the soils, despite their perceived abundance, while phosphate monoesters in the remaining soils consisted of the alkaline hydrolysis products of RNA and phospholipids. Organic phosphorus concentrations were greater in soils rich in organic matter, but there were no apparent differences between soils under conventional flooded rice cultivation and the system of rice intensification. Additional experiments are now required to assess the role of organic phosphorus in the nutrition of rice growing under a range of management and soil conditions.

Up-core variations of these benthic biofacies record the evolution of depositional environments during the past 8000 years in this long-occupied Eastern Mediterranean port. The most important change occurred in the mid-Holocene between approximately 6300 and approximately 4300 yr ago, a time of lower sea level and minimal human activity. This faunal change, indicating a transition from a somewhat protected to a more open and higher-energy marine environment, resulted primarily from rise of sea level, lowering of the harbour floor and diminished shielding by Pleistocene coastal ridges and reefs near the bay mouth and within the harbour. Since that time, faunal assemblages have remained generally constant, except during the period from 2100 to approximately 1800 yr ago when Greeks and Romans built the Heptastadion that connected Alexandria to Pharos Island; this construction effectively separated the Eastern from the Western Harbour. Absence of a well-marked faunal change during the past 18 centuries is unexpected, particularly in light of the much-increased population and associated human effects. The harbour's overall large size, rise in relative sea level and continued exchange of marine water between the open shelf and port have maintained an active circulation pattern. The strong current regime and reworking of bottom sediments have generally masked short-term human effects and altered the harbour's late-Holocene sediment stratigraphy. These factors help explain why benthic biofacies primarily record influences of natural processes that prevailed in this relatively unconfined, high-energy marine setting rather than those of a more constricted and anthropogenically impacted port.

Four assemblages have been distinguished on the basis of their specific minerals: calcite, amethystine quartz, spodumene and emerald. The early stage of vein development was characterized by the crystallization of massive quartz, followed mainly by the precipitation of Ca-Fe-Mg carbonates. The occurrence of Be-, Li-, Ti-, and B-bearing minerals coupled with local contamination by Cr and V is largely penecontemporaneous with the formation of cavities. Late precipitation of pyrite, chabazite- and graphite suggests that low temperatures and reducing conditions were prevalent duing the waning stages of mineral precipitation. The presence of cogenetic high- and low-X/(CO (sub 2) ) fluid inclusions in quartz indicates that an aqueous carbonic fluid reached a state of immiscibility duing vein formation. No relationship with granitic pegmatites was seen. EPMA results are reported for beryl, spodumene, tourmaline, rutile and zircon.

With this aim, biostratigraphic information, i.e. first (FO) and last (LO) occurrence events of benthonic and planktonic foraminifera was analysed from sixteen wells from the Lower Magdalena Valley (LMV). The inconsistencies found in the biostratigraphic record, i.e. varying successions of first and last appearances of species from well to well as a result of several factors such incomplete sampling and preservation, true variation in the distribution of fossil taxa, etc., and the great amount of biostratigraphic data makes it practically impossible to accurately constrain basin history from biostratigraphic information by unaided visual inspection. This motivates the treatment of biostratigraphic information with new quantitative approaches, such as constrained optimization (CONOP9 software) and graphic correlation concepts (GraphCor 3,0) and the comparative method approach of Cooper et al. (2001). The succession of biostratigraphic events found through the application of each technique was statistically filtered and compared with Kendall tau coefficients whose values were 0,8. An optimal biostratigraphic succession of LOs was found and calibrated with the Berggren et al. (1995) global time scale by a LOESS regression model for the middle Eocene-Pliocene interval, thus revealing three major changes in sediment accumulation rates for the basin during this time interval: (1) middle Eocene to Oligocene, with low accumulation rates, (2) early Miocene to middle Miocene, with high accumulation rates and (3) late Miocene to Pliocene, with lower accumulation rates. The calibrated composite succession enabled the construction of age-well depth plots, which indicate periods of local deposition and accumulation rates, and periods of erosion, no deposition or very low accumulation rates (unconformities). The best plots were used to build a model for the correlation of unconformities, which shows that they are heterochronous, lasted at least 2,5 Ma, and are of limited extent. Finally, a correlation model was proposed that includes: (1) a time-calibrated succession of biostratigraphic events, and (2) a Haq curve that shows how each geologic period is recorded in each well.

All occur at active margin settings, typically characterized by accretionary complexes lithologies and as tectonic blocks within serpentinite-matrix melange. Peak lawsonite-eclogite facies mineral assemblages (garnet+omphacite+lawsonite+rutile) typically occur in prograde-zoned garnet porphyroblasts. Their matrix is commonly overprinted by higher-temperature epidote-bearing assemblages; greenschist- or amphibolite-facies conditions erase former lawsonite-eclogite relics. Various pseudomorphs after lawsonite occur, particularly in some blueschist/eclogite transitional facies rocks. Coesite-bearing lawsonite-eclogite xenoliths in kimberlitic pipes and lawsonite pseudomorphs in some relatively low-temperature ultrahigh-pressure eclogites are known. Using inclusion assemblages in garnet, lawsonite eclogites can be classified into two types: L-type, such as those from Guatemala and British Columbia, contain garnet porphyroblasts that grew only within the lawsonite stability field and E-type, such as from the Dominican Republic, record maximum temperature in the epidote-stability field. Formation and preservation of lawsonite eclogites requires cold subduction to mantle depths and rapid exhumation. The earliest occurrences of lawsonite-eclogite facies mineral assemblages are Early Paleozoic in Spitsbergen and the New England fold belt of Australia; this suggests that since the Phanerozoic, secular cooling of Earth and subduction-zone thermal structures evolved the necessary high pressure/temperature conditions. Buoyancy of serpentinite and oblique convergence with a major strike-slip component may facilitate the exhumation of lawsonite eclogites from mantle depths.

The preliminary examination of these samples shows that the nonvolatile portion of the comet is an unequilibrated assortment of materials that have both presolar and solar system origin. The comet contains an abundance of silicate grains that are much larger than predictions of interstellar grain models, and many of these are high-temperature minerals that appear to have formed in the inner regions of the solar nebula. Their presence in a comet proves that the formation of the solar system included mixing on the grandest scales.

The mean elemental composition of this Wild 2 material is consistent with the CI meteorite composition, which is thought to represent the bulk composition of the solar system, for the elements Mg, Si, Mn, Fe, and Ni to 35%, and for Ca and Ti to 60%. The elements Cu, Zn, and Ga appear enriched in this Wild 2 material, which suggests that the CI meteorites may not represent the solar system composition for these moderately volatile minor elements.

This assemblage is the earliest known complex deep-sea biologic community based on decaying wood as its primary source of nutrients. The 495 recovered fossils (exclusive of foraminiferans) belong to 21 species; 7 species relied directly on the wood, either by ingesting it or by feeding on xylophagous microbes; these species are also the most abundant. Seven species were predators or scavengers that were most likely attracted by the wood-dependent species. The remaining seven species represent predators, detritus feeders, and suspension feeders that may or may not have had a relation to the wood fall or its fauna. All species had a benthic mode of life, and pseudoplanktonic taxa are absent, indicating that the colonization of the wood began only once it had arrived on the deep-sea floor. The wood-dependent species belong to taxa that fill the same ecologic niche in the deep sea today, indicating that the modern wood-fall ecosystem had evolved at least by late Eocene time. There is no uniformity or specialization of dispersal strategies among the recovered taxa; they rather reflect those of the phylogenetic group to which they belong. The wood-fall assemblage described here shares several families with fossil whale falls and cold seeps but very few species, a condition that can also be observed at modern examples of these ecosystems.

When the focus of management activities is mammals, it is difficult to monitor their populations in a way that is rapid, effective, and inexpensive. We report on a mammal survey of a reserve in southwest China using remote-trip cameras. We surveyed 329 locations over 2 field seasons in 2002 and 2003. Sixteen species of mammals were detected with these cameras, with four species documented for the first time. After accounting for variation due to slope, aspect, elevation, and habitat type, the distribution of six species was positively associated with the location of conservation stations and/or patrolling routes. Species of medium-sized mammals are excellent candidates for monitoring programs based on these cameras, due to their relative abundance, sufficient size to be detected by the camera units, and sensitivity to human activity. The distribution of mammals relative to management efforts is a relatively rapid means to assess reserve effectiveness. The repeat use of the cameras as part of a monitoring plan should provide a quantifiable measure of reserve effectiveness.

Despite this long history, there has been little discussion of how model parameters may be estimated from real paleontological data. In this paper, I outline a likelihood-based framework for fitting and comparing models of phyletic evolution. Because of its usefulness and historical importance, I focus on a general form of the random walk model. The long-term dynamics of this model depend on just two parameters: the mean ( mu sub(step)) and variance ( sigma super(2) sub(step)) of the distribution of evolutionary transitions (or 'steps'). The value of mu sub(step) determines the directionality of a sequence, and sigma super(2) sub(step) governs its volatility. Simulations show that these two parameters can be inferred reliably from paleontological data regardless of how completely the evolving lineage is sampled.In addition to random walk models, suitable modification of the likelihood function permits consideration of a wide range of alternative evolutionary models. Candidate evolutionary models may be compared on equal footing using information statistics such as the Akaike Information Criterion (AIC). Two extensions to this method are developed: modeling stasis as an evolutionary mode, and assessing the homogeneity of dynamics across multiple evolutionary sequences. Within this framework, I reanalyze two well-known published data sets: tooth measurements from the Eocene mammal Cantius, and shell shape in the planktonic foraminifera Contusotruncana. These analyses support previous interpretations about evolutionary mode in size and shape variables in Cantius, and confirm the significantly directional nature of shell shape evolution in Contusotruncana. In addition, this model-fitting approach leads to a further insight about the geographic structure of evolutionary change in this foraminiferan lineage. JF - Paleobiology AU - Hunt, G AD - Gene Hunt.

Here we show that forest fragmentation provokes surprisingly rapid and profound alterations in Amazonian tree-community composition. Results were derived from a 22-year study of exceptionally diverse tree communities in 40 1-ha plots in fragmented and intact forests, which were sampled repeatedly before and after fragment isolation. Within these plots, trajectories of change in abundance were assessed for 267 genera and 1,162 tree species. Abrupt shifts in floristic composition were driven by sharply accelerated tree mortality and recruitment within approximately 100 m of fragment margins, causing rapid species turnover and population declines or local extinctions of many large-seeded, slow-growing, and old-growth taxa; a striking increase in a smaller set of disturbance-adapted and abiotically dispersed species; and significant shifts in tree size distributions. Even among old-growth trees, species composition in fragments is being restructured substantially, with subcanopy species that rely on animal seed-dispersers and have obligate outbreeding being the most strongly disadvantaged. These diverse changes in tree communities are likely to have wide-ranging impacts on forest architecture, canopy-gap dynamics, plant-animal interactions, and forest carbon storage.

A phylogenetic analysis of 16 cytochrome oxidase subunit 1 (CO1) haplotypes revealed three clades: one basal clade containing genetically disparate haplotypes from Mindanao, and two derived clades, one of which was largely confined to the largest island, Luzon, and one that was widespread except for Luzon. For the Luzon clade, nested clade analysis revealed an isolation-by-distance effect, and a mismatch distribution analysis diagnosed a recent demographic expansion (sum of squared deviation, SDD = 0.0093, P= 0.075), which mirrors demographic attributes found in mainland primary malaria vectors and could inflate estimates of gene flow from F sub(ST). For the widespread clade, evidence of range expansion and past fragmentation and/or long distance colonization from the Visayas or Mindanao to Palawan is suggested. A south-to-north range expansion of An. flavirostris is suggested; estimates of coalescence for the Luzon clade was 214 000 years ago (ya) (95% confidence interval 35 600-298 000 ya), i.e. late Pleistocene. Present day rather than Pleistocene island association and some, but not all, sea barriers appeared to be important for An. flavirostris population structure. Our results suggest that endemic island malaria vector species need to be considered before any generalizations are made about the population structure of primary and secondary vectors.

For vertebrates, one of the most important terrestrialized groups, this event was interrupted by a time interval known as Romer's Gap, for which, until recently, few fossils were known. Here, we argue that geochronologic range data of terrestrial arthropods show a pattern similar to that of vertebrates. Thus, Romer's Gap is real, occupied an interval from 360 million years before present (MYBP) to 345 MYBP, and occurred when environmental conditions were unfavorable for air-breathing, terrestrial animals. These model results suggest that atmospheric oxygen levels were the major driver of successful terrestrialization, and a low-oxygen interval accounts for Romer's Gap. Results also show that terrestrialization among members of arthropod and vertebrate clades occurred in two distinct phases. The first phase was a 65-million-year (My) interval from 425 to 360 MYBP, representing an earlier, prolonged event of complete arthropod terrestrialization of smaller-sized forms (425-385 MYBP) and a subsequent, modest, and briefer event of incipient terrestrialization of larger-sized, aquatic vertebrates (385-360 MYBP). The second phase began at 345 MYBP, characterized by numerous new terrestrial species emerging in both major clades. The first and second terrestrialization phases bracket Romer's Gap, which represents a depauperate spectrum of major arthropod and vertebrate taxa before a major Late Paleozoic colonization of terrestrial habitats.

AN - 68249369; 17168017 AB - The importance of facilitation to local community dynamics is becoming increasingly recognized. However, the predictability of positive interactions in stressful environments, the balance of competition and facilitation along environmental gradients, and the scaling of local positive interactions to regional distributions are aspects of facilitation that remain unresolved. I explored these questions in a habitat specialist, Delphinium uliginosum, and a moss, Didymodon tophaceus, both found in small serpentine wetlands. I tested three hypotheses: (1) moss facilitates germination, growth, and/or fecundity of D. uliginosum; (2) facilitation is stronger at the harsher ends of gradients in soil moisture, toxicity, and/or biomass; and (3) facilitation is reflected in positive associations at the levels of local abundance and regional occurrence. Although considerable competitive interactions occurred in later life stages, moss strongly facilitated D. uliginosum seedling emergence. There was no evidence that this facilitative effect weakened, or switched to competition, in benign environments. D. uliginosum was more locally abundant and more frequently present, across a large portion of its range, with than without moss, indicating a net facilitative effect in the face of competitive influences. Facilitated recruitment, possibly by seed retention, was found to be an important control on abundance and distribution in this rare species.

The coral association comprises 16 taxa which belong to 9 families: Dictuophyllia conferticostata (Vaughan), Cladocora jamaicaensis Vaughan, Cladocora gracilis (d'Orbigny), Antiguastrea cellulosa (Duncan), Multicolumnastraea cyathiformis (Duncan), Placocoenia major Felix, Siderastrea vancouverensis Vaughan, Siderastrea adkinsi (Wells), Goniopora sp., Actinacis haueri Reuss, Actinacis parvistella Oppenheim, Actinhelia elegans (Goldfuss), Meandrophyllia oceani (de Fromentel), Dermosmiliopsis orbignyi Alloiteau, Trochoseris aperta Duncan, and Cyathoseris formosa d'Achiardi. The corals described herein were collected from mixed coral-rudist and coral-dominated assemblages in the Arroyo de la Atarjea, and one unnamed riverbed which lithologically correspond to the Arroyo de la Atarjea section, both of which belong to the upper member of the Cardenas Formation. On the genus level, 94% of the Mexican fauna corresponds to the Maastrichtian coral assemblages of Jamaica. Moreover, the Cardenas fauna shows close affinities to both Upper Cretaceous coral associations of central Europe and the Caribbean, as well as to Lower Tertiary faunas of Central America and the Caribbean. On the species level, 68.8% of the Cardenas corals are known from Lower Tertiary strata of Central America, the Caribbean, South America, Asia, European/Mediterranean region, and/or southeastern parts of the USA.

The abrupt eastward drop in relief between these provinces gives rise to unstable conditions and consequent gravitational collapse of large volcanic edifices built at the edge of the Altiplano. Eastward sloping substrate, caused by the irregular configuration of the basement rocks, is the dominant factor that controls the direction of collapsing sectors in all major volcanoes in the region to be preferentially towards the GCP. These collapses produced voluminous debris avalanches and lahars that inundated the well-developed drainages and clastic aprons that characterize the Coastal Plain. Large catastrophic collapses from Citlaltepetl, Las Cumbres, and Cofre de Perote volcanoes are well documented in the geologic record. Some of the avalanches and transformed flows have exceptionally long runouts and reach the Gulf of Mexico traveling more than 120 km from their source. So far, no direct evidence has been found for magmatic activity associated with the initiation of these catastrophic flank-collapses. Apparently, instability of the volcanic edifices has been strongly favored by very intense hydrothermal alteration, abrupt topographic change, and intense fracturing. In addition to the eastward slope of the substrate, the reactivation of pre-volcanic basement structures during the Late Tertiary, and the E-W to ENE-SSW oriented regional stress regimes may have played an important role in the preferential movement direction of the avalanches and flows. In addition to magmatic-hydrothermal processes, high amounts of rainfall in the area is another factor that enhances alteration and eventually weakens the rocks. It is very likely that seismic activity may be the principal triggering mechanism that caused the flank collapse of large volcanic edifices in the Eastern Mexican Volcanic Belt. However, critical pore water pressure from extraordinary amounts of rainfall associated with hurricanes or other meteorological perturbation cannot be ruled out, particularly for smaller volume collapses. There are examples in the area of small seismogenic debris flows that have occurred in historical times, showing that these processes are not uncommon. Assessing the stability conditions of major volcanic edifices that have experienced catastrophic sector collapses is crucial for forecasting future events. This is particularly true for the Eastern Mexican Volcanic Belt, where in many cases no magmatic activity was associated with the collapse. Therefore, edifice failure could occur again without any precursory warning.

The upper 152 m consist of a silty sandstone combination, interpreted as transition-zone deposits, grading vertically into sandstone containing hummocky cross stratification, amalgamated beds, and, in the lower part, a few storm beds rich in invertebrates, especially mollusks. The sandstone was deposited in the shoreface environment within a prograding (regressive) wave-dominated deltaic system. The shoreface sandstone interfingers with overlying braided-river deposits of the Pleistocene Saugus Formation. Sixty-six species of marine invertebrates, mostly mollusks, were collected in the shoreface deposits and are indicative of normal marine salinities. Sixty-two species are found throughout central and Southern California and are indicative of warm-temperate conditions. Four species have only been previously found either in the southern part of Southern California and/or in Baja California, Mexico, where they are associated with subtropical paleoenvironments: the bivalves Argopecten invalidus (Hanna, 1924), Lyropecten catalinae (Arnold, 1906), and Placunanomia hannibali Jordan and Hertlein, 1926, and the gastropod Acanthinucella emersoni (Hertlein and Allison, 1959). In addition, the oyster Myrakeena veatchii (Gabb, 1866), which is an especially common component of warm-water fossil assemblages in Baja California, even though it can be found as far north as central California, is the most common mollusk in the Valencia area. "Ostrea" veatchii is here reassigned to genus Myrakeena Harry, 1985. Lyropecten gallegosi Jordan and Hertlein, 1926, is here regarded as a junior synonym of L. catalinae. The age of the Pico Formation in the Valencia area is late Pliocene, based on benthic foraminifera and mollusks.

We assess four methods that can be used to estimate the height of aeolian dunes on Mars. These are (1) stereography, (2) slip face length, (3) profiling photoclinometry, and (4) Mars Orbiter Laser Altimeter (MOLA). Results show that there is good agreement among the methods when conditions are ideal. However, limitations inherent to each method inhibited their accurate application to all sites. Collectively, these techniques provide data on a range of morphometric parameters, some of which were not previously available for dunes on Mars. They include dune height, width, length, surface area, volume, and longitudinal and transverse profiles. The utilization of these methods will facilitate a more accurate analysis of aeolian dunes on Mars and enable comparison with dunes on other planetary surfaces.

Avian malaria in particular has contributed to the extinction and endangerment of Hawaii's native avifauna, and has altered the altitudinal distribution of native bird populations. We examined the population genetic structure of Cx. quinquefasciatus on the island of Hawaii at a smaller spatial scale than has previously been attempted, with particular emphasis on the effects of elevation on population genetic structure. We found significant genetic differentiation among populations and patterns of isolation by distance within the island. Elevation per se did not have a limiting effect on gene flow; however, there was significantly lower genetic diversity among populations at mid elevations compared to those at low elevations. A recent sample taken from just above the predicted upper altitudinal distribution of Cx. quinquefasciatus on the island of Hawaii was confirmed as being a temporary summer population and appeared to consist of individuals from more than one source population. Our results indicate effects of elevation gradients on genetic structure that are consistent with known effects of elevation on population dynamics of this disease vector.

AN - 19984594; 7279632 AB - Marine studies on herbivory have addressed the role of algae as food and shelter for small consumers, but the potential of benthic cyanobacteria to play similar roles is largely unknown. Here, feeding preferences were measured for eight invertebrate consumers from Guam, offered four common macroalgae and two cyanobacteria. The survivorship of another consumer raised on either macroalgae or cyanobacteria was also assessed. From the choices offered, the sacoglossans Elysia rufescens and E.ornata consumed the green macroalga Bryopsis pennata. The crab Menaethius monoceros preferred the red alga Acanthophora spicifera. The amphipods Parhyale hawaiensis and Cymadusaimbroglio consumed macroalgae and cyanobacteria in equivalent amounts, with C. imbroglio showing less selectivity among diets. In contrast to these patterns, in these assays the gastropods Stylocheilus striatus, Haminoea cymbalum, H.ovalis, and Haminoea sp. fed exclusively, or survived only, on cyanobacteria. Preferences for different cyanobacteria varied. Field surveys of cyanobacteria-associated species yielded 34 different invertebrate taxa and suggested different degrees of specificity in these associations. Tropical mesograzers exploit considerably different food resources, with some species adapted to consume cyanobacterial mats. Benthic cyanobacteria may play important roles as food and shelter for marine consumers and may indirectly influence local biodiversity through their associated fauna.

Pumiliotoxins are highly toxic and are believed to protect frogs against predators. Their potential activity against ectoparasites, however, has not been investigated. We tested female yellow fever mosquitoes (Aedes aegypti) for responses to 8-hydroxy-8-methyl-6-(2'-methylhexylidene)-1-azabicyclo[4.3.0]nona n e, designated pumiliotoxin 251D [PTX (+)-251D], a skin alkaloid present in all genera of dendrobatids and in other anurans, and to its unnatural enantiomer, PTX (-)-251D. Both enantiomers of PTX 251D presented on silicone feeding membranes reduced landing and feeding by A. aegypti, but PTX (+)-251D did so at lower concentrations. PTX (+)-251D also induced toxicosis, shown when mosquitoes failed to fly off membranes. Similarly, mosquitoes confined with copper wires coated with PTX (+)-251D exhibited greater latencies to fly off the substrate and a higher incidence of leg autotomy than did those confined with the (-)-enantiomer. Our results on the contact toxicities of PTX 251D enantiomers parallel those reported for mice injected with them. The presentation of serial dilutions of PTX (+)-251D to A. aegypti revealed a minimum toxic concentration of 0.1 mu g/cm super(2). This value is substantially lower than that estimated for the cutaneous abundance of this compound in some frogs, an observation consistent the function of PTX 251D in anuran chemical defense against ectoparasitic arthropods.

2010-095748 AB - Caribbean reefs have been ecologically volatile over the last 30 yr. Two of the dominant, framework-building corals, Acropora palmata (elkhorn coral) and Ac. cervicornis (staghorn coral), were killed en masse by a regional outbreak of white-band disease (WBD) beginning on the late 1970s and extending though the early 1990s. The apparently contrasting stability of coral assemblages on a scale of tens to hundreds of thousands of years in the fossil record is either the result of time-averaging (damping of past decadal-scale volatility), or it represents a long record of persistence (decadal-scale persistence summing to long-term stability). Cores extracted from lagoonal reefs in Belize showed that Ac. cervicornis dominated continuously for at least the last 3-4 kyr. Beginning in the late 1980s, WBD virtually eliminated Ac. cervicornis, and Agaricia tenuifolia (lettuce coral) increased opportunistically to become the dominant coral species at intermediate depths. Likewise, Ag. tenuifolia recently became dominant at intermediate depths in a coastal lagoon on the Caribbean side of Panama. As in Belize, the shift in Panama was unprecedented on a millennial scale; however, its cause (altered patterns of land use) and the identity of the previous dominant (the finger coral Porites furcata), were different. After millennia of monotypic dominance, depth zonation emerged for different reasons in the two reef systems, increasing the between-habitat component of diversity in both taxonomic and functional terms. The increase in between-habitat diversity caused a decline in geographic-scale variability as the two systems converged on a single, historically novel pattern of depth zonation. Opposite trends in biotic variability at the habitat and geographic levels highlight the complex, unprecedented, and scale-dependent nature of the response of coral reefs to intense perturbations over the last several decades.

Broadband LIBS of minerals captures the spectrum (200 to 980 nm) of photons emitted by a plasma produced during laser ablation of the mineral surface. The spectrum contains information about essentially the entire periodic table, although LIBS is more sensitive for the light elements. In this study, LIBS analyses of 135 beryl samples (inclusion-bearing and gem-quality) from 20 countries (11 US states) and Antarctica are used to investigate geologically significant applications of LIBS technology. Although LIBS spectra can be calibrated to determine certain elements of interest, specifically the very light elements B, Be, and Li, at ppm levels, this study focuses on applications that use the broadband spectra: stoichiometric substitutions, gem provenance, and identification of individual gem stones. The complex stoichiometry of beryl is reflected in LIBS analyses. In beryl (Be (sub 3) Al (sub 2) Si (sub 6) O (sub 18) ), substitution of Li (super +) for Be (super 2+) and divalent ions for Al (super 3+) is compensated in part by the presence of water, hydroxyl, and alkali ions (Na (super +) , K (super +) , Rb (super +) , and Cs (super +) ) in open channels parallel to the c-axis. These variations are seen in the beryl broadband spectra, where positive correlations exist between Li, Mn, and Fe peak intensities and those of Na and K. Broadband spectra are perhaps most useful for comparison of the overall chemical signatures of samples, with applications in the unique identification of individual stones for insurance purposes and determining the provenance of individual samples. Regression of single-shot broadband spectra of gem-quality beryls against beryl spectra in our database indicates that LIBS analysis can uniquely identify individual stones with a 86% success rate. The question of provenance is complicated by complex processes in pegmatites; however, beryls in our collection show a broad affinity to their craton (Laurentia, Gondwana, Baltica, and the mobile belts of western North America and South America).

The transition to the Anisian (Middle Triassic) marks the true recovery, with stabilization of carbon isotopes, diversification of benthic, planktonic and nektonic marine groups, the reappearance of Lazarus taxa, and of first scleractinian reefs. The carbon isotopic studies of Payne have established that environmental perturbations were likely the major cause for the delayed Triassic recovery, focusing attention on the dynamics of events from the Smithian-Spathian boundary into the Anisian-Ladinian. The application of logistic growth models suffers both from a lack of positive feedback effects and a lack increasing returns with scale, and externally imposed limits to growth. Although hyperbolic models incorporate positive feedback effects through dependency of species interactions for increased diversity, they can still externally limit growth. Endogenous growth theory from economics suggests a way out of this dilemma, with increased diversity a consequence of the spillovers from ecosystem engineering and niche construction. Applied to the Triassic recovery, such an approach suggests the recovery was driven by endogenously driven growth; increases in what ecologists commonly term carrying capacity.

The concentrations of the elements present in the sample are quantified by measuring the intensity of their emissions. The advantages of PXRF are that no sample preparation is required and the method is non-destructive. The accuracy of PXRF was investigated using 23 standard rock reference materials and 8 elements (Ti, Mn, Fe, Zn, Rb, Sr, Zr, and Mo) that are determined by PXRF. Linear regressions of known concentrations against PXRF analyses yield RSquare values near 1 (0.82 to 0.995), indicating the robustness of PXRF analysis. This provenance study uses a statistical analysis of PXRF analyses to determine whether a beryl can be traced back to its geological province, district, mine, or its zone within a pegmatite. Preliminary discriminant function analysis has been performed using concentrations of Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Rb, Sr, Ag, Cd, Sn, Ba, Hg, and Pb in 101 beryls from 17 countries (9 US states) and Antarctica. It is significant that Cr, Cu, As, Zr, Mo, Ag, Cd, Hg, and Pb are the most important elements in reducing misclassifications, compared with Ti, Fe, Mn, Co, Ni, Rb, Sr, and Ba. The importance of the chalcophile elements in this discriminant function analysis suggests that pegmatite beryls may be recording major cratonic signatures, as observed in metallogenic provinces. On-going work includes statistical analysis of PXRF analyses of 84 beryls whose locations are known sufficiently well to place them within specific cratons or mobile belts. This database also allows us to examine provenance at the scale of single pegmatites and pegmatite fields.

Granitic pegmatites are widely distributed throughout the Appalachian Belt and consist of a diversified spectrum of pegmatite types characterized by: 1) variable mineral paragenesis, textures and internal structure; 2) bulk compositions that may include enrichment in rare alkalis (e.g., Li, Rb, Cs), high-field strength elements (e.g., Nb, Ta, Sn), rare-earth elements (including Y, U and Zr), and volatile components (e.g., B, F); 3) relationships to syn-tectonic, post-tectonic and anorogenic granitic plutons intruded at shallow to deep crustal levels; and by 4) emplacement into greenschist to amphibolite facies metamorphic rocks. These criteria allow for the division of the Appalachian Pegmatite Province into the New England, Mid-Atlantic and Southern Subprovinces. The New England Subprovince (Maine, New Hampshire, Massachusetts, Connecticut and Rhode Island) is best characterized by relatively shallow emplaced pegmatites with patterns of rare-element enrichment (e.g., Li, Rb, Cs, Be, Ga, Sn, Ta > Nb, B, P, and F) that can lead to extreme fractionation and highly diversified mineralization. Parental granites generally show S-type chemistry. The Mid-Atlantic (southern New York, New Jersey, Pennsylvania, Maryland and Virginia) and Southern (North Carolina, South Carolina, Georgia and Alabama) Subprovinces host pegmatites that were emplaced at deeper levels with primitive to moderately evolved geochemical signatures. Parent granitoids may be absent to poorly differentiated with S- to I-type signatures. Pegmatites enriched in Nb > Ta, Ti, Y, REE, Zr, Be, U, Th, and F are typically related to granitoids with A-type chemistry and are more prominent in the New England Subprovince. Although the magmatic and tectonic histories of pegmatite generation in the Appalachians has never been fully defined, field relations and radioactive age determinations suggest that pegmatite emplacement spans a period in excess of 400 Ma and largely postdates major orogenic events (e.g., Taconic, Acadian and Alleghenian).

A major component of their ecological success is the ability to produce new colonies asexually via fragmentation of adult colonies as well as by larvae derived from sexual reproduction. The existence of these alternative strategies raises basic questions about the environmental factors that should favor sexual versus asexual reproduction. Theories about the maintenance of sex and dispersal predict that asexual propagation should persist in stable environments while sex should be more beneficial in areas of high environmental instability. In contrast, life history theory of growth and recruitment predicts that asexual propagation should be favored in areas of high productivity versus sexual reproduction in low productivity environments. We tested these alternative predictions for eight common species of Cupuladria in the southwestern Caribbean over the past 10 Ma. Oceanographic conditions in the region changed from high variability and productivity to low variability and productivity between 5-3 Ma as the rising Isthmus closed off the Caribbean from the Pacific. Remarkably, most of the life history variability was intraspecific with seven of the eight species persisting for 10 to 4.5 Ma. Among the eight species, the proportion of sexually derived colonies increased by 10 to 55% and the calcification index increased from 33 to 90%. Four of the eight species also became more dome-shaped. Thus, colonies of each species became progressively stronger, squatter, and smaller, all of which are traits that reduce rates of asexual reproduction by fragmentation. These trends are consistent with life history theories about growth and recruitment and contradict models regarding maintenance of sex or dispersal. However, the trends persisted long after the period of major environmental change, suggesting that ongoing changes in overall community composition were also important selective factors for increased sexual reproduction. The results are strong evidence for the importance of environmental change as a driving factor in life history evolution.

Despite of this great record, few biostratigraphic researches have been carried out in this region. Only five papers have published in the last 60 years (Germeraad et al. 1968, Regali et al., 1974, Lorente, 1986, Muller et al., 1987, and Hoorn, 1993). Several biostratigraphic zones were established using traditional biostratigraphic methods based on presence and/or abundance of key species such as Psiladiporites minimus, Verrutricolporites rotundiporus, Echitricolporites maristellae, Crassoretitriletes vanraadshoovenii, Grimsdalea magnaclavata and Asteraceae pollen. We are analyzing several complete Neogene sections in the eastern foothills of central Colombia, Urumaco region in western Venezuela, and several isolated outcrops in the Amazonas of Brazil. This new information is combined with all the biostratigraphic data available for the region using Graphic Correlation and Constrained Optimization. Several zones have been produced and compared with those proposed in earlier studies. Preliminary results have been showed that the Miocene biostratigraphic markers have wider first and last occurrences that earlier studies suggest as well as a strong environmental influence.

Granitic pegmatites are the focus of many studies due to the great variety of minerals they contain, their importance as major sources of gem materials and their unusual chemical composition. Pegmatites are generated from highly evolved aqueous fluids derived from the fractionation of granitic magmas and may be enriched in rare alkalis (e.g., Li, Rb, Cs), high field strength elements (e.g., Nb, Ta, Sn), rare-earth elements and volatile components (e.g., B, F) in concentrations that are significantly higher than found in most igneous rocks. These elements are key to establishing the fractionation level for individual pegmatites or pegmatite fields, as well as providing clues to the tectonic setting of the granite-pegmatite system. Two new natural reference materials were prepared and characterized at the Smithsonian Institution, to provide an avenue to pursue the geochemical analysis of granitic pegmatites: the Stewart Lepidolite (STL-1), USNM 174041, and the Zapot Amazonite (ZA-1), USNM 174042. STL-1 was prepared with lepidolite collected from the lithium-rich Stewart pegmatite, San Diego County, California (33 degrees 22'52"N, 117 degrees 03'41"W). The ZA-1 was prepared with an amazonite from the topaz-bearing Zapot Pegmatite, Mineral County, Nevada, (38 degrees 41'N, 118 degrees 33'W). STL-1 and ZA-1 were analyzed by wet chemistry (Si, Al, Ca, Mg and Fe), spectrophotometry (Mn, P and Ti), flame photometry (Li, Na, K, Rb and Cs), ICP-MS (Ga, Nb, Sn, Cs, Tl). The XRF analysis of random splits showed a high degree of homogeneity.

They are: a Late Silurian to Late Devonian (Phase 1, 60 m.y. long) interval of myriapod and apterygote hexapod herbivores on several clades of primitive vascular-plant hosts; a Late Mississippian to end-Permian (Phase 2, 125 m.y. long) interval of mites and apterygote and basal pterygote herbivores on pteridophyte and basal gymnospermous plant hosts; a Middle Triassic to Recent (Phase 3, 245 m.y. long) interval of mites, orthopteroids and basal hemipteroid and holometabolan herbivores on pteridophyte and gymnospermous plant hosts; and a mid Early Cretaceous to Recent (Phase 4, 115 m.y. long) interval of orthopteroids and derived hemipteroid and holometabolous herbivores on angiospermous plant hosts. These host-plant and arthropod-herbivore associations are mediated by eight functional feeding groups: external foliage feeding, piercing-and-sucking, boring and palynivory (all early Phase 1 origins); galling, seed predation and nonfeeding oviposition (all early Phase 2 origins); and leaf mining (an early Phase 3 origin). Within about 20 m.y. of each herbivore expansion, a major biota is present for which evidence documents the full or almost complete spectrum of later plant-arthropod associations. These four associational phases are linked to paleoclimatologic variables of greenhouse/icehouse cycles and atmospheric O2 and CO2 levels by uncertain causes, albeit some relationship probably is present. The eight functional feeding groups persist through most of the 420 m.y. sampled interval, but contain host-plants and arthropod herbivores that are spatiotemporally ephemeral, indicating considerable iterative evolution of associations. Poor understanding of associations in Phases 1 to 3 is attributed to disproportionate focus on both extant and fossil angiosperm-holometabolan insect associations.

However, these correlations are difficult due to chronostratigraphic uncertainties and the isotope overprint created by microbial degradation and diagenesis. In contrast, geochemical biomarkers are unaffected by these two processes, thereby allowing a reliable estimate of the plant isotopic signal. To evaluate the possibility of using carbon isotope ratios as a chronostratigraphic tool, we are comparing the Paleocene-Eocene marine carbon-isotope record with that of a terrestrial sequence from Colombia. Sediments of the terrestrial rock units were deposited in a transitional setting dominated by mudstones, coals, and small lenses of sandstones (Catatumbo and Barco Formations) and in a mixture of deltaic and fluvial conditions (Cuervos Formation). The stratigraphic control was based on palynological zones for the region. Isotope results for the studied terrestrial sequence show the same three carbon-isotope excursions found in the marine carbonate record. Terrestrial isotope values decreased from -24ppm to -26.5ppm in the oldest event. This shift is commonly associated with the recovery of the primary production after the K-T extinction event. A positive shift is present in the late Paleocene, with values increasing from -26.5ppm to -23.8ppm. This event appears to be related to the burial of large amounts of organic matter. The third excursion is found near the Paleocene-Eocene boundary, with values changing from -23.8ppm to -26.5ppm. The shift is commonly interpreted to result from the release of large amounts of methane. Our preliminary results highlight the possibility of correlating marine and terrestrial sequences using carbon isotopes.

They are believed to be different both in origin and composition. Vesta appears to have a basaltic surface, indicating at least partial melting. Remote sensing observations, combined with mathematical modeling and comparison to meteorites suggest this asteroid was differentiated into a core, mantle and crust, making it the largest differentiated body in the asteroid belt. A major reason for continued interest in Vesta is that it is thought to be the parent body for HED meteorites, the most voluminous class of achondrites, due to compositional and spectral similarities. This family consists of cumulate orthopyroxenites (diogenites), and basalts/gabbros (eucrites) as well as regolith breccias containing clasts of both materials (howardites). Gaffey (1997) observed sub-hemispheric color and spectral variations across the surface of Vesta, corresponding to regions of differing mineralogies. He was able to produce a generalized lithologic map of Vesta using these results. We can build upon such work by using the HED meteorites as a spectral groundtruthing tool for DAWN in order to produce more accurate geologic maps of Vesta's surface. This study focuses on the eucrite member of the HED family (specifically the unbrecciated eucrites), and attempts to quantify the petrologic factors that have the greatest impact upon their spectra (grain size, mineral chemistry, and texture). Eucrites are primarily composed of pigeonite and plagioclase, with varying amounts of silica and opaque phases (usually ilmenite, chromite, and sulfides). However, despite their similarities, we are able to see great petrologic variability, from quench-textured, rapidly-cooled lithologies, to coarse, exsolved, slowly-cooled, cumulate types. Such variability is also reflected within their spectra and our results show that we are able to distinguish between different types of eucrites--potentially corresponding to different lithologies on the surface of Vesta--using their spectra alone.

However, heliocentric distance, and thus surface temperature, has a significant effect on the spectra of olivine-rich asteroids. We show that composition and temperature complexly interact spectrally, and must be simultaneously taken into account in order to infer olivine composition accurately. Using near-infrared data obtained at the NASA Infrared Telescope Facility (IRTF) on Mauna Kea with SpeX, a low- to medium-resolution near-infrared spectrograph (0.8 to 2.5 mu m) and pre-existing visbile spectra we examine the spectra of olivine dominated asteroids. We find that most (7/9) of the olivine-dominated asteroids are magnesian and thus likely sampled mantles differentiated from ordinary chondrite sources (e.g., pallasites). However, two other olivine-rich asteroids (289 Nenetta and 246 Asporina) are found to be more ferroan. Melting models show that partial melting cannot produce olivine-rich residues that are more ferroan than the chondrite precursor from which they formed. Thus, even moderately ferroan olivine must have non-ordinary chondrite origins, and therefore likely originate from oxidized R chondrite or melts thereof, which reflect variations in nebular composition within the asteroid belt. This is consistent with the meteoritic record in which R chondrites and brachinites are rare relative to pallasites.

Radar images (resolution of 100m/pixel) are presented for 24th October 2005, for a region covering the south pole and the nearside to latitude approximately 68 degrees S; the geology here is dominated by highland terrain of overlapping ejecta from nearby craters and the major basins. Shackleton appears to be younger than neigbouring craters such as de Gerlache, Shoemaker or Faustini and probably dates to the Eratosthenian period. Smooth-textured terrain lies between the highland massifs, and high circular polarization rarios (CPR) relative to the surrounding region indicate abundant cm-scale to dm-scale rocks in the upper few m of the regolith. Shackleton is morphologically similar to the 17 km crater Schomberger G, with layered outcrops within the upper few 100 m of their interior rim deposits (radar images), making physical access to the interior walls extremely difficult. The high-resolution radar data showed no evidence that high CPR values in Shackleton or elsewhere in the south polar region correlate with solar illumination conditions, but are associated with the rugged inner walls and proximal ejecta of impact craters consistent with (1-2%) water ice being present only in disseminated grains.

As shown by previous work, chalcocite (Cu (sub 2) S) transforms to covellite (CuS) by the oxidation of Cu (super 1+) to Cu (super 2+) and the loss of Cu from the mineral structure. Mathur et al. (2005) have demonstrated that the Cu isotope composition of the solids becomes lighter during this reaction. In the current study, we have explored time-resolved X-ray diffraction as a means of monitoring the many intermediate phases that are part of the reaction sequence. Pure, naturally occurring chalcocite powders were placed in flow-through capillary reaction cells and exposed to aqueous solutions of 0.01 M and 0.1 M ferric sulfate for approximately 2 hrs. Real-time diffraction data were collected at intervals of 2 min at beam line X7B, National Synchrotron Light Source, using a MAR345 imaging plate. The delta (super 65) Cu values of the starting and final powders were measured using a Finnigan Neptune multi-collector inductively coupled plasma mass spectrometer. The powder diffraction data clearly revealed that chalcocite passes through a complex series of partially oxidized intermediate phases during its transformation to covellite. Reaction kinetics for the 0.1 M ferric sulfate experiments were sufficiently rapid that covellite appeared within 10 min at room temperature, whereas the same reaction progress was only achieved after 90 min with the 0.01 M solution. The greater time resolution afforded by the slower reaction rates allowed observations of the following intermediate phases: djurleite (Cu (sub 1.94) S), digenite (Cu (sub 1.80) S), anilite/roxybite (Cu (sub 1.75) S), geerite (Cu (sub 1.6) S), spionkopite (Cu (sub 1.4) S), and yarrowite (Cu (sub 1.13) S). These intermediate reaction steps were characterized by the presence of 2 or more phases. Preliminary isotope results indicated that the original chalcocite powders had delta (super 65) Cu values of 0.45 + or - 0.04ppm and the residual covellite powders had delta (super 65) Cu values of -14.15 + or - 0.04ppm. Coupling isotopic analyses obtained during the entire reaction sequence with our time-resolved XRD results will make it possible to associate Cu fractionation behavior with specific mineral phases.

Vesta has reflectance spectra similar to the HEDs (howardites, eucrites, and diogenites) and is commonly thought to be the parent body of these meteorites. Vesta is also the largest object in a family of asteroids and many asteroids in this family also have reflectance spectra similar to Vesta and the HEDs. These objects with HED-like spectra are commonly called Vestoids and have been found throughout the inner main belt and in the near-Earth asteroid population. Vestoids are relatively small objects, usually with estimated diameters of 10 km or less. Approximately seventy Vestoids have been identified in the main belt and approximately fifteen Vestoids in the near-Earth asteroid population on the basis of visible and/or near-infrared reflectance spectra. We have obtained near-infrared reflectance spectra of a number of Vestoids using the SpeX instrument at the NASA IRTF (Infrared Telescope Facility), which allow for average pyroxene mineralogies to be estimated for these objects since the SpeX spectra encompass both the 1 and 2 im absorption features. SpeX spectra have currently been obtained on Vesta and approximately twenty-five main-belt and near-Earth Vestoids. These spectra are currently being analyzed to try to determine the mineralogies of these objects and the minimum ejection velocities from Vesta needed for these objects to reach their present orbits. Approximately 90% of observed main-belt Vestoids have calculated minimum ejection velocities from Vesta of approximately 1 km/s or smaller. A few Vestoids have ejection velocities between 1 and 2 km/s. Excluding 1459 Magnya, which is located at 3.15 AU, the only known Vestoid with a minimum ejection velocity from Vesta greater than 2 km/s is 1468 Zomba (2.20 AU). We are currently determining if the composition of the Vestoids varies with minimum ejection velocity from Vesta and if all Vestoids have mineralogies consistent with being derived from Vesta.

Eros is irregularly shaped (35 X 10 X 10 km) with a surface that includes a global regolith, asymmetrically distributed boulders, heavily cratered surface, and grooves and ridges recording deformation. The spectrally-derived mineral compositions and olivine:pyroxene ratio, absence of a global magnetic field, and the Mg/Si, Al/Si and Ca/Si ratios and K concentrations point to a primitive, chondritic body, while a depletion in sulfur and differences in Fe/Si and Fe/O ratios from the X-ray and gamma-ray experiments are likely due to metal and sulfide migration due to partial melting throughout the entire asteroid or, more likely, processing of the regolith layer by micrometeorite bombardment, sputtering and/or size/density segregations. Synthesis of the spectral and chemical data suggest the most likely meteoritic analog is either an ordinary chondrite composition that experienced alteration at the surface or less likely a primitive achondrite formed from an ordinary chondritic precursor. Recent work has renewed debate about the geological history of Eros. Newly-derived determinations of chondritic levels of Cr, Mn and Ni from X-ray spectra strongly argue against a partial melting origin for the S depletion, while a spectrally-derived FeO-rich pyroxene composition might favor partial melting and/or a chondritic composition enriched in FeO relative to ordinary chondrites. A similar debate is taking place about the geologic history of asteroid 25143 Itokawa, the target asteroid for the Hayabusa mission. Given inherent uncertainties in orbital data and our incomplete knowledge of the chemical and physical processes occurring in asteroidal regolith, these debates will likely remain unresolved pending asteroid sample return.

This study correlates the ages and paleoenvironments of newly sampled fossiliferous deposits of coastal Ecuador (forearc Borbon and Manabi Basins) and the Caribbean and Pacific sides of Central America, including the Chucunaque and Sambu Basins of Pacific eastern Panama, Charco Azul Group of Pacific Panama-Costa Rica, Limon Basin of Caribbean Costa Rica, and Bocas del Toro and Panama Canal Basins of Caribbean Panama. Below we highlight the new results from Ecuador. The stratigraphic succession examined spans lower Oligocene-Pleistocene, middle bathyal to shallow neritic sediments, and includes several significant unconformities. BORBON BASIN: Sections of the middle to upper bathyal Pambil Fm. are lower Oligocene to lower Miocene. The unconformably overlying outer-middle neritic Angostura Fm. is of late Miocene age ( approximately 11-8.3 Ma, ages of Berggren et al. 1995); the hiatus is >10 m.y. in one section and 16 m.y. in another. At Punta Verde, the middle Miocene, bathyal Viche Fm. unconformably underlies the Angostura Fm.; the hiatus is >1.4 m.y. The outer neritic-upper bathyal lower Onzole Fm. overlies the Angostura Fm. and ranges from 10.7-5.6 Ma in age. Further south, the mid-Pliocene, middle bathyal upper Onzole Fm. ranges approximately 4-2.8 Ma in age. MANABI BASIN: Samples examined from the bathyal Tosagua Fm. are middle and upper Miocene (the latter equivalent to the Portoviejo Fm.). In the south it is directly overlain by the Pleistocene Canoa Fm., separated by an unconformity of >14 m.y. The Pleistocene, inner neritic Tablazo Fm. overlies and possibly intergrades with the Canoa Fm. The upper Miocene Guayacan Fm. (10.9-6 Ma) is directly overlain by the upper Miocene (8.3-6 Ma) Bahia Fm. The neritic Jama Fm. is also upper Miocene (8.6-5.3 Ma). These results extend and refine those of previous studies.

Species investing in a high LMA tend to have lower mass-based photosynthetic rates but achieve longer leaf lifetimes (LL), such that their lower revenue per unit investment per time is compensated by a longer-lasting revenue stream. This LMA-LL trade-off is also coordinated with variation across species in dark respiration rates, leaf nitrogen and phosphorus concentrations, and insect herbivory rates, forming a "leaf economics spectrum". Thus far, investigation of the leaf economics spectrum has been limited to present-day vegetation because of the inability to determine LMA for fossils. Here we show for woody angiosperms a new and easily-measured scaling relationship between petiole and lamina dimensions that enables the estimation of LMA for compressed fossil leaves, and thus the positioning of past species along the leaf economics spectrum. Application to two well-understood Eocene lake floras (Republic, Washington, USA; 49 Ma and Bonanza, Utah, USA; 47 Ma) quantifies the contrasting ranges of leaf functional diversity between sites and demonstrates for the first time a significant negative correlation between LMA and insect herbivory, consistent with extant floras.

In contrast, blocks from more southerly parts of the Franciscan melange belt are more commonly mid-ocean ridge and ocean island/seamount basalts. The data indicate a north-south variation in the block population, due to differences in source terrane, or in the processes that provided the blocks and transported them into the melange, or both. We suggest that, in the northern Franciscan, a relatively greater fraction of igneous melange blocks was emplaced by block slumping from the forearc crust into the trench than was the case to the south.

Paracostellagerina nov. gen. is characterized by asymmetrical test ornamentation, rugosities, and costellae that are meridionally arranged on the umbilical side and parallel to the periphery on the spiral side. This genus has a global distribution within tropical-subtropical latitudes and, because of its short stratigraphic range, it is a valuable biomarker for correlation of uppermost Albian-lowermost Cenomanian sequences.

In that time there has been remarkable progress in bringing together geochronologists, stratigraphers, and paleontologists/evolutionary biologists with a common appreciation of the value and power of a highly resolved record of earth history. We have sponsored three workshops, a short course, and several topical sessions at international meetings. The geochronology communities are engaged in a major effort to eliminate inter-technique and inter-laboratory biases, the main limitations to the goal of the initiative. EARTHTIME prepared, calibrated and began distributing a mixed 205Pb-233U-235U-tracer solution for use in high-precision U-Pb geochronology, and several zircon standards were prepared and distributed. Use of these materials will eliminate much of the inter-laboratory bias. In Ar-Ar geochronology, we have sponsored distribution of multiple samples, including large quantities of the Fish Canyon sanidine as a preferred monitor. The EARTHTIME project continues to foster cooperation between geochronologists and stratigraphers/paleontologists. It encourages approaches such as CONOP-9 that can produce composite sequences for thousands of first- and last-appearance events of fossil taxa together with other time-stratigraphic events, including dated tephra-falls. When integrated with high-precision geochronology, these composite sequences can break barriers to resolving power imposed by traditional zones and stages, and will allow, for example, continuous serial estimates of species richness as a function of time. EARTHTIME is developing an active program of education and public outreach and increasing awareness within the geoscience community. The outreach effort led by the Radius Project at the Denver Museum of Nature and Science has created a 30-minute geochronology video, curricula, and live data casts between EARTHTIME researchers and middle school students.

Of particular note are the numerous microvertebrate-bearing sites of this region, which have been studied to examine faunal change across the K/T boundary. The Koenig site, a new microvertebrate-bearing locality from the lower Hell Creek Formation in Petroleum County, Montana, is described here and compared to well-known sites in eastern Montana, Wyoming and Canada. This site is of particular significance because the fossil bearing horizon occupies a relatively low stratigraphic position, close to the boundary with the underlying Fox Hills Formation, which represents a slightly earlier time interval than most known Hell Creek microvertebrate sites. Also, its location places it among the most western of these sites, geographically extending the existing sample of Lancian microvertebrate communities. Specimens were surface collected from a fossiliferous layer within a tan, well-sorted, fine-grained sandstone bed that was deposited about 160 km west of the continental seaway. Specimens were identified to the most precise taxonomic level possible (often this was family level or higher due to excessive water-wear) and were assigned to one of several diet and habitat categories, based on morphology, previous studies, and/or similar extant relatives. At the Koenig site, diversity is highest among dinosaurs, followed by osteichthyans, then turtles. Specimen abundance is highest for osteichthyans, then dinosaurs and turtles. The fauna is dominated by terrestrial or amphibious taxa, consisting mostly of small carnivores. Although the site is both earlier and farther west than most Lancian-age sites, it shows broad similarities with them in taxonomic content and abundances. In general, the Koenig site produced more dinosaur specimens and significantly fewer amphibian and mammal specimens, but these differences are more likely taphonomic than environmental. The Koenig site fauna supports the interpretation that much of the Hell Creek depositional environment shared a similar vertebrate fauna throughout most of Lancian time, and suggests that little substantial change occurred prior to the end of the Cretaceous.

However, the responses of insect herbivores to the climatic and floral change across this boundary have not been well-studied. The research presented here is part of a larger project to examine changes in insect damage on angiosperm leaves in the Western Interior, USA, through the Paleogene. We focus here on insect damage in Wyoming's Bighorn Basin during the late Paleocene and early Eocene (59-55 Ma), with particular emphasis on the Paleocene-Eocene Thermal Maximum (PETM). Mean annual temperatures gradually warmed by approximately 4 degrees C through the late Paleocene, abruptly increased by approximately 5 degrees C in the PETM, and returned to pre-PETM values in the early Eocene. We test how these changes affected the diversity and frequency of insect damage. We conducted insect damage censuses at five sites in the Bighorn Basin, including a site within the PETM. At each locality, over 800 identifiable dicot leaves were scored for insect damage using the damage morphotypes (DTs) of Labandeira et al. These DTs can be divided into those typical of generalist insects and those strongly associated with specialist herbivores. Damage metrics were compared using resampling analyses to standardize for sample size. Both total and specialized damage diversity show a significant increase during the latest Paleocene (Clarkforkian 3), reach a maximum in the PETM, and decline slightly in the early Eocene. This pattern is visible on the bulk floral assemblages, as well as individual plant species. Less than 38% of angiosperm leaves from the three Paleocene localities contain insect damage, whereas 56% of the PETM leaves are damaged. In this study, increased insect damage diversity and frequency correlate with increases in temperature. The elevated herbivory on the thermophilic PETM flora is consistent with modern ecological studies suggesting that raising temperature increases the abundance and diversity of insect herbivores.

Temporal resolution of 100 kyr (0.02%) and eventually even 50 kyr into the early Paleozoic now seems likely. Such techniques have already allowed the generation of a high-resolution temporal framework for the Ediacaran-Cambrian radiation of metazoa, helped greatly narrow the duration of the great Permo-Triassic mass extinction thus eliminating some hypothesized causes and sharpening our testing of others, and narrowed the duration of the oceanic anoxic event at the Cenomanian-Turonian (Late Cretaceous) boundary. Questions now best explored in the late Cenozoic, including the relationship between climatic and evolutionary change, synchoneity of environmental change with evolutionary and ecological events, and rates of evolution can now be more rigorously explored deeper into the fossil record. But exploiting these new possibilities will require paleontologists to improve methods to integrate these methods, improve our understanding of the analysis of evolutionary rates, and confront the challenges of settings where geochronologic resolution may be greater than paleontologic resolution.

To interpret coastal evolution here we made the following: a seismic survey; a petrologic analysis of dated sediment in cores and excavations along the coast; and a petrographic study of rock used for building the site's temple. Located in the tectonically active Calabrian Arc, the sector has been subject to considerable rise of land onshore ( approximately 1 mm/yr), and an equivalent rate of seafloor subsidence. A distinct Holocene beachrock sandstone and conglomerate sequence is traced 400 m from landward of the beach to the inner shelf. Correlation of this sequence helps define complex coastline migration patterns from before Greek settlement to the present. The shoreline shifted landward, to seaward, and then back to landward due to up-and-down motion in the sector between the alluvial plain behind the beach and innermost shelf. By mid-Holocene, the shoreline had advanced 300 m seaward resulting in emergence of a broad arcuate coastal headland seaward of the site. The shore's return landward then resubmerged the margin and artifacts after Kaulonia's abandonment, probably in Roman time. However, no lagoon, permanent lake, or man-made port for protected anchorage was found. Vessels sailing to Kaulonia were beached and/or anchored nearshore and perhaps within the Assi River mouth. Beachrock sandstone composition in sections on land is similar to sandstone observed offshore and to rock used for temple base construction. Extensive sandstone exposures along the former coast may be one reason Greeks selected this site for colonization.

This study examines morphological variability and size selectivity in veneroid bivalves during the Plio-Pleistocene extinction in Florida, USA. The Plio-Pleistocene extinction (1.8 Ma) resulted in the extinction of approximately 65% of bivalves in the Caribbean and western Atlantic. Species were designated as victims and survivors based on stratigraphic occurrences compiled from the literature. Fourteen pairs of closely related species were selected for analysis, each pair including one survivor species and one species that became extinct during this interval. More than 1500 specimens were examined from collections at the Florida and Virginia Museums of Natural History, representing 27 localities from the Caloosahatchee, Jackson Bluff, and Nashua Formations and the Pinecrest Beds in Florida. Specimens were digitally imaged, and landmark coordinate points were collected from the hinge, adductor muscles, pallial line, and points representing maximum length and height. Generalized Procrustes Analysis was applied to superimpose landmark configurations, and Procrustes Root Mean Square was calculated as an overall measure of multivariate morphological variability. Centroid size was computed to quantify body size. Differences in morphological variability and body size between victim-survivor pairs were assessed using parametric and non-parametric statistical tests. Results indicate that survivors were significantly more variable than victims. The variability difference persists, but is no longer significant when comparisons are controlled by locality. This result may be a consequence of reduced statistically power, or possibly indicate a role for ecophenotypy in accounting for variability differences. In contrast to morphological variability, body size does not appear to significantly affect survivorship in veneroid bivalves during this event. These results suggest that morphological variability may be a significant factor in promoting the survivorship of veneroid species during the Plio-Pleistocene extinction.

Origination generally preceded extinction but peaks in extinction ranged from 4-3 Ma for bivalve mollusks to 2-1 Ma for gastropods and reef corals. Cheilostome assemblages also changed dramatically, especially in terms of the relative abundance and diversity of erect, encrusting, and free-living taxa. However, problems of cryptic species have obscured the timing of the rise and fall of diversity of the different growth forms and thus the environmental correlations of their diversification and extinction. Our taxonomic revision of the abundant free-living genus Cupuladria provides an opportunity to compare patterns of origination and extinction in Cupuladria with those for predominantly erect Metrarabdotos and encrusting Stylopoma studied previously. As expected, 15 of the 17 Cupuladria species were undescribed taxonomically compared to 23 out of 34 new species in the other two genera. Relative timing of maximum diversity, origination, and extinction differed greatly. Origination of Cupuladria peaked in the middle Pliocene and diversity increased until a strong peak in extinction in the early Pleistocene halved the number of species. In contrast, origination of Metrarabdotos peaked in the late Miocene and extinction peaked in the early Pliocene, and Stylopoma origination peaked twice in the late Miocene and Pleistocene while only 1 of 19 species became extinct during the entire 10 Ma. Thus, of the 50 species in these genera, the percentage of erect species declined from 42 to 7% (1 of the 3 recent Metrarabdotos species is encrusting) while that of encrusting species increased from 32 to 66% and free-living species from 26% to 43% before falling back to 28%. Data on skeletal abundance suggests the ecological footprint of these trends was even greater since free-living species are the most abundant bryozoans by weight in late Pliocene to recent samples whereas erect species dominated in the late Miocene. With the exception of massive forms like Celleporaria, encrusting species have been a minor ecological component of the fauna despite their great increase in diversity. Thus, the major ecological shift was from dominance by erect to free-living species that appears to have been driven by the collapse in productivity in the late Pliocene as the Panamanian portal closed.

Paleontologists have long studied such examples of phyletic evolution in order to better understand the processes and patterns of evolutionary change. In recent years, a number of statistical tests have been developed to determine the mode of evolutionary change, with a focus on discriminating between directional evolution, (unbiased) random walks, and stasis. Here, I describe a model-based approach for assessing the mode of evolutionary change in phyletic sequences. This approach is based in likelihood, and correctly accounts for sampling error as a source of variation among samples. It has the important advantage over previous methods that no model is granted privileged null status; all models are evaluated on an equal footing based on their compatibility with observed data, using standard model-selection tools such as the Akaike Information Criterion (AIC). I develop this approach to evaluate the trichotomy of evolutionary modes usually considered: directional change (modeled as a biased random walk), nondirectional change (modeled as an unbiased random walk), and stasis (as modeled by Sheets and Mitchell, 2001). This statistical framework was applied to a large sample of over 100 evolutionary sequences compiled from the published literature. For each sequence, I fit three models corresponding to the standard modes of evolutionary change and evaluated the adequacy of the models using the AIC and related measures of model support. Only rarely, in less than 10% of cases, does the model of directional change best account for evolutionary patterns; even this modest percentage is almost certainly an overestimate due to investigator bias. Of the remaining sequences, approximately half are best fit by the unbiased random walk model, with the remaining best described by stasis. Analyses performed thus far do not find any systematic differences in evolutionary mode with respect to taxonomic groupings or trait type (size versus shape characters). These results support the view that periods of strongly directional evolution are rare and/or brief, and, over paleontological time-scales, most traits and lineages experience meandering or fluctuating evolutionary trajectories.

Lawsonite eclogite from Jalapa Department, Guatemala contains several generations of lawsonite, two generations of garnet, as well as titanite and apatite in microstructures that suggest domainal fluid-rock interaction. Two samples (01GSn2-14 and MVE02-SS-07) were analyzed by bulk ICP-MS and LA-ICP-MS. Sample 2-14 shows a sloped, LREE-rich whole-rock pattern, with La 50x and Sm 30x Chondrite. It contains lawsonite as: 1) 50-100mu m, subidiomorphic inclusions in inclusion-rich cores of 3-5mm Garnet (sub 1) ; 2) 200-400 mu m, irregular inclusions in inclusion-poor rims of Garnet (sub 1) ; 3) 100-300 mu m idiomorphic matrix grains, partly consumed by retrograde amoeboid titanite; 4) 100-300 mu m, idiomorphic grains with 100-200 mu m idiomorphic matrix grains of Garnet (sub 2) ; and 5) 300-600 mu m idiomorphic grains in late veins. Each lawsonite type manifests distinct LREE abundances and fractionations. Sample SS-07 displays a flat, approximately 20x Chondrite LREE pattern. It contains two types of lawsonite: 25-50 mu m inclusions in mm-sized garnet, and 10-20 mu m inclusions in titanite. A lawsonite core near a garnet core contains 400x Chondrite La, in a steep LREE-rich pattern, whereas a lawsonite core in the garnet rim contains 20x Chondrite La in a flatter pattern. Lawsonite inclusions in titanite display flat LREE at 60-70x Chondrite. Titanite and apatite are LREE-poor and range from approximately 4-20x Chondrite La. In these rocks, lawsonite-producing and consuming reactions record a sequence of domainal equilibration of LREE with the same (or similar) major mineral assemblages. Because lawsonite contains most of the LREE in the rock, the variations of composition are likely due to differences in fluid compositions attending near-peak and retrograde crystallization, all under extremely low-T conditions.

Such techniques have already allowed the generation of a high-resolution temporal framework for the Ediacaran-Cambrian radiation of metazoa, helped greatly narrow the duration of the great Permo-Triassic mass extinction and eliminated several hypothesized causes, and narrowed the duration of the oceanic anoxic event at the Cenomanian-Turonian (Late Cretaceous boundary). Temporal resolution of 100 kyr (0.02%) or even better into the early Paleozoic now seems likely, opening a host of new questions for reliable investigation. Further exploiting the possibilities of these techniques will require paleontologists to improve methods to integrate these disparate techniques, improve our understanding of the analysis of evolutionary rates, and confront the challenges of settings where geochronologic resolution may be greater than paleontologic resolution.

Fluid inclusions in jadeitites from slices of serpentinite-matrix melange along the Motagua Fault zone (MFZ) in Guatemala should therefore provide a direct estimate of the fluid composition(s). The inclusions contain low salinity brines trapped in several different P-T regimes at low to moderate subduction-zone geothermal gradients. Jadeitite occurrences along the MFZ extend for >150 km on the north and 25 km on the south. In jadeitites north of the MFZ from Pachalum (Granados) to Panaluya (Rio Hondo), initial fluid inclusion results testify to salinities that range from 3 to 7 wt% NaCl equivalent. However, these are not pure NaCl fluids, as initial melting temperatures are depressed. Some samples show salinity variations linked to changes in cathodoluminescence color. There is also a range in homogenization temperatures from low in early jadeite to high in secondary jadeite, which may reflect changes either in T or P during jadeitite formation. Northern jadeitites probably all formed in the same P-T regime of 6 to10 kb and 300 to 400 degrees C, based on their similar mineral assemblages. In contrast, petrologic data suggest that south of the MFZ jadeitites represent 3 distinct P-T regimes. The one sample analyzed so far for fluid inclusions (from La Ceiba) has a mineral assemblage preliminarily interpreted as P approximately 10 to 14 kb and T <300 to 400 degrees C. It contains lower salinity fluid inclusions (0 to 2 wt% NaCl equivalent), and lower homogenization temperatures than counterparts from north of the MFZ. Jadeitite samples from the other two P-T regimes south of the MFZ await analysis. Overall, our results show a range in low salinity fluids that implies the subduction fluid was dominated by one fluid that underwent minor changes in chlorinity and ionic strength during deposition of jadeitite, while facilitating the striking contrasts in abundances of LIL and LREE recorded by these rocks. Having lived in Guatemala, Maria Luisa Crawford wanted to study these rocks but political and exposure complexities prevented it. We are most fortunate to have Weecha's insight into aqueous fluid inclusions to guide our work. At this Theme Session we congratulate her upon her retirement from "active" teaching.

By supporting the GIP Program, AWG satisfies its mandate to provide compelling opportunities for, and to showcase the work of, professional women geoscientists. In addition, we help to fill the NPS's need for professional-level researchers. AWG funds up to four GIP opportunities per year; selected projects generally require previous scientific, technical, research, and project-specific expertise and have the potential for high-profile scientific results, management applications and/or outreach products. AWG's partnership with NPS involves a set of administrative tasks done in part by AWG and in part by NPS. Streamlining of this process is ongoing as GIP and park needs and scenarios change yearly. GIPs report a range of experiences in scheduling, supervision, logistics, and finalizing the research either at or away from the parks. AWG's GIPs have dealt with diverse topics including paleontology, stratigraphy, coastal processes, wetlands delineation, vegetation mapping, glacial and fluvial processes, cave inventory, petrified tree stabilization and basic research. GIPs appreciate these unique opportunities to contribute to understanding of geologic history, resources and physical processes, historical preservation and educational outreach that cannot be addressed by resource management staff at these parks. Geology is recognized as an under-addressed natural resource in the NPS, yet knowledge of the physical environment is fundamental to managing numerous biological and cultural issues within the parks. AWG, as a geological professional society, is therefore committed to maintaining its involvement and funding, exploring flexibility options, developing larger-scale projects for graduate research or sabbatical activities, and increasing the outreach components of the GIP program to promote geologic education and awareness to the public.

These summer workshops are conducted as a series of three-day short courses that explore the geological and paleontological record of the Bighorn Basin and Big Horn Mountains. Workshop participants learn to read and interpret the geologic record of paleoenvironments, paleoclimate, ancient ecosystems, and mountain building events. In addition, new techniques and concepts are taught that can be readily adapted to various grade levels. Teachers taking the workshops for recertification credit must develop and submit a lesson-plan derived from their workshop experience. Assessment of the program based on discovery-based exercises, post-workshops evaluations, and anecdotal feedback indicate that participants substantially increase their confidence and interest in teaching earth-science concepts. The "History of life in northern Wyoming" course will be presented as an example of one of the recent workshops offered by GeoScience Adventures.

Non-conventional (super 14) C dates from the shallow reef crest coral Acropora palmata had previously been used to reconstruct sea level, while bulk, non-conventional (super 14) C dates from intertidal Rhizopora mangle peat have been routinely used to mark past sea-level positions in microtidal carbonate environments. This reconstruction included more recent high precision TIMS U-Th and (super 14) C coral data to account for gaps in the coral record. Error corrections to ages and elevations were applied where possible. All (super 14) C dates were calibrated using the Calib programs. Separately, both the peat and coral datasets incorporate sufficient age and elevation uncertainties and error to heavily impact each one's accuracy for sea-level determinations. However, when combined, data from these paleoenvironmentally-related facies bracket the position of sea level in the form of a smooth curve with two breaks in slope signifying progressive reductions in the rate of sea-level rise during the Holocene. Currently these datasets lack the time/depth resolution to allow for identifying any sea-level response to rapid climatic events, or for quantifying differential isostatic histories between study sites. Recent work, however, has allowed testing and validation of the curve's position as well as its utility in interpreting paleo reef and mangrove histories. In addition, the curve provides a reliable reference point for interpreting the record of major storm activity during the Holocene. Advances in (super 14) C dating methods since these samples were dated will be assessed using new peat data. Rates of sea-level rise during the Holocene are compared with current Caribbean and Gulf coast rates, as well as with projected rate increases and storm surges under climate warming scenarios.

S., through a system of canals. In 2005 a particularly large discharge of fresh pollutant-saturated water resulted in losses of seagrass, bivalves, and diseased and dying fish. A program to monitor the macrofauna and assess its future is now underway. A comparison with the past, of course, is only possible if a baseline exists. Unlike the macrofauna, in 1975/76, such a baseline was established for the foraminifera. Thirty years later in 2005, the same area was re-sampled for foraminifera. In 1975/76 the mean density was 280 per 20 ml of sediment. In 2005, we observed a mean of 46 per 20 ml of sediment, a decline of 83%. In 1975/76 we observed 62 species while in 2005 we observed 13, a decline of 79%. The most abundant species constituted 42% of the fauna in 1975/76; in 2005 it had risen to 76%, a dramatic increase in dominance. The dramatic difference between the baseline and the present is plotted on a biodiversity gram (BDG) which depicts the canonical ensemble of species richness, compound diversity and evenness against the number of individuals on a single diagram.

G. Abbot and A. Wetmore. The context in which it was found, an attachment to a forwarding letter, suggests this was designed as a standard piece to be sent to all public inquiries concerned with evolution. The three-page statement notes that the Smithsonian, Bureau of American Ethnology and Zoo all collect objects "to increase the knowledge of the public." "The Institution makes no preference between rival religions or rival theories in its collections and exhibitions of objects illustrating facts." In regard to human evolution "the opinions of those [of the staff] best qualified to judge unanimously support that theory..." The statement then list 11 lines of evidence. Those of most interest in geological context are: increase in brain size through times; similarity in structure to other mammals; "every order of life shows similar evidences of development..."; fossils show a "progressive change" with man in the youngest strata; sequences of rock indicate the long expanse of geologic time; radio-activity further expands that time sequence; evolution in stars suggests "that evolution is a universal process to which man is no exception. The statement ends by noting that a belief in organic evolution is not "exclusive and destructive of religious belief..."

It is associated with a significant extinction of many groups. The palynological record from mid latitudes shows a dramatic and abrupt disappearance of most dominant taxa and nearly all of the Late Cretaceous angiosperms following the KP boundary. An estimated loss of approximately 30-50% of palynomorph species has been seen throughout the western Interior of North America. The effect of the KP boundary on the vegetation of tropical latitudes is not known. Were extinction levels of tropical vegetation more intense than in temperate communities? To address this question we have studied 62 palynological samples across the KP boundary of a stratigraphic section in Cesar-Rancheria Basin (northern South America). Several techniques including range through method, rarefaction, per-capita extinction and origination rates, measures of taxonomic diversity, confidence intervals on stratigraphic ranges and Chi Square were used to estimate tropical extinction levels. There is a taxon extinction of 60-70% associated with the boundary and a significant change in the rate of extinction. Origination rates do not seem to be affected. The Paleocene floras are fully dominated by angiosperms, while the Maastrichtian is co-dominated by angiosperms, ferns, and gymnosperms showing that there are important changes in neotropical floras across the KP boundary, far more intense than in temperate regions.

These conulariids exhibit unusual preservation in a number of regards. Some are preserved on their sides with the apical end at one end of the specimen and the aperture at the other, as is the case in most conulariids. Others have been transversely flattened with tears along the midlines in the apertural ends of the faces, yielding a maltese cross-like appearance. One specimen shows the replication in silica of a series of tear-shape pouches accompanied by thinner canals that were associated with the corners, that apparently radiated from the central axis of the animal. These tissues were evidently deformed and incompletely preserved, hindering straightforward interpretation, but preliminary analysis suggests that there may have been four of the thinner canals, each separating a set of four of the larger pouches. This may accord with the four radial canals associated with muscle bands, and gut partitioned into four radial pockets seen in adult Stauromedusae (and in adult pelagic Cubomedusae), but only if each gut pocket were subdivided into a further four pouches. Another possibility is that the pouches housed gonads. Although we have yet to recognize definitive synapomorphies linking this specimen to extant groups, the radial symmetry evident in the soft tissues supports a cnidarian-grade affinity.

Underground coal mines provide unparalleled opportunities to map such spatial distribution of fossil plant assemblages in relation to their environments. We carried out such mapping in five mines of southern Illinois and southwestern Indiana. All five exploit thick, low-sulfur Springfield Coal along the margins of an ancient river channel (Galatia channel) that existed during peat formation. The mines span a distance of 125 km along the channel. Fossil plants are abundant in gray shale (Dykersburg Shale) immediately overlying the coal. The Dykersburg represents mud deposited as the Galatia channel became an estuary (fresh to slightly brackish, tidally influenced) when the coastline was drowned due to basin subsidence and/or eustatic sea-level rise. Tree stumps, particularly of the lycopsid trees Lepidodendron and Sigillaria, commonly are preserved in growth position, signifying abrupt burial of the peat. They are associated with well preserved remains of foliage and tree trunks of a variety of plant groups, indicating autochthonous and parautochthonous preservation. Sedimentation rates of several tens of cm per year are estimated by counting tidal rhythmites in the Dykersburg. Although overall species diversity is high across the study area, vegetation is clumped into compositionally distinct patches of low internal diversity. Such patches sometimes can be related to peat-swamp topography and distance from the channel. We are finding similar patterns in the slightly younger Herrin and Danville Coals of the same region.

Plant communities at high latitudes responded rapidly with major but transient compositional turnover. The long-term effects on tropical vegetation communities that stem from the brief period of global warming are unclear. We present pollen data from the paratropical U.S. Gulf Coast (eastern Mississippi, western Alabama and Georgia) which had background Paleogene mean annual temperatures of 26-27 degrees C. Sporomorph data (pollen and spores) demonstrate that taxonomic diversity increases over nearly equal 1 my in the late Paleocene but this trend is replaced, with the first occurrences of taxa that mark the early Eocene (e.g. Granulatisporites luteticus, Nuxpollenites psilatus, Interpollis microsupplingensis, and Brosipollis spp.), by a pronounced extinction into the early Eocene nearly equal 20% of the palynoflora). Taxonomic diversity also decreases by up to 38% in the early Eocene. The timing of the extinction is not clearly resolved but may be restricted to the earliest part of the early Eocene. Two richness estimators (Chao 2 and Jackknife 2) both demonstrate that late Paleocene samples contain significantly more taxa than those in the early Eocene. However, these estimates are compromised in part by the varying amounts of time contain within each bin. Extinction on the U.S. Gulf Coast proves that ancient tropical ecosystems were highly susceptible to changes in diversity mediated directly or indirectly by environmental change even during equable greenhouse climates in the early Paleogene.

AN - 50134097; 2009-095469 AB - One advantage of being an octogenarian, especially if you have a modicum of memory remaining, is that you become a living data-bank for all the geologic lore that has come your way during a half-century of field and laboratory experiences. A common problem today, now that many geologic results are digitally developed and announced on the web to an eagerly awaiting geoscience community, is that the basic geologic evidence is never, or hardly ever, re-examined. Occasionally the perpetrator of such a synthesis may be stricken by conscience and wonder if a "new look" at an old fossil might substantiate or change the results. So, who might know the answer? Perhaps an old pal from graduate school days (or 1960s field work in northern Alaska) would remember. Especially if he has been in, or near, a repository of "geologic stuff" (not necessarily a museum) for that half-century, or so. The subsequent phone call (or e-mail) pleads: "Do you remember in the summer of 1972..."; or "Where can I find the recent brachiopods discussed by a Dr. Morse in the mid-1880s..."; or "We have been arguing about fossils in metamorhpic rocks-- where might we find collection X from Y?" Not surprisingly, in these days when whole departments, let alone basic subdisciplines, disappear from universities, many geologic PhD's have never been exposed to the logistics or folk history of collecting and preserving collections--let alone understand what a type specimen is and how it is documented. The above scenarios, among others, are discussed with the hope of enlightening a few of the folks who might well be asking similar questions in the future.

A foreland tectonic sequence is related to one pulse of deformation bounded at the base by amalgamated sandstones in the foredeep and correlative unconformity in the distal foreland. Uppermost strata of a foreland sequence consists of muddy intervals with upsection increase of detrital content in coincidence with decrease of accommodation space. The proximal foredeep presents accumulation of dark-colored mudstones while deposition of amalgamated sandstones occur in the distal foreland, as migration of the flexural uplift advance. Four pulses of deformation in the EC were identified by the analysis of palinspastically restored foreland tectonic sequences. The Maasthrichtian-lower Paleocene sequence consists of marginal to marine quartzarenites covered by paralic to fluvial coal-bearing strata. The upper Paleocene foreland sequence records northward and eastward migration of amalgamated fluvial quartzarenites, litharenites and subarkoses, which are overlain by dark-colored mudstones and channel-fill litharenites. Paleocene orogenic loads (1-km-thick mud-rich strata and deltaic quartzarenites, sublitharenites and arkoses, and amalgamated fluvial quartzarenites in the distal foreland basin. Orogenic loads of 3-6 km high correspond to exhumed massifs that latter reached area near the Llanos foothills. Foreland geometry and basin fill analysis help constructing kinematic models of the EC. Even though thermochronology and paleoecological techniques contribute to understand the process of orogenic exhumation and surface uplift, the study of post-middle Miocene volcanics and associated hydrothermal activity in the EC, and analysis of Paleogene humid climate conditions, emerge as new techniques constraining the study of deformation in the EC.

AN - 50054932; 2010-031529 AB - The Silurian Diana Mills Pluton ( approximately 21 km (super 2) ) is a metamorphosed mafic-ultramafic body in the Piedmont Province of central Virginia. It occurs within the Mine Run Complex, a melange zone that extends from central Virginia through Maryland. Originally viewed as intrusive into adjacent metagraywackes, the mass has more recently been interpreted as tectonically emplaced, perhaps by gravity sliding. Rock types include metagabbro, hornblendite, and metaperidotite. In addition, unusual serpentinites with a hint of orbicular texture occur at four localities. These occurrences consist of abundant tan-weathering clasts in a dark green matrix. Clasts range in length from <0.5 up to approximately 12 cm, and many are somewhat ellipsoidal; others are more angular and even rectangular. Some show a thin (<5 mm) shell of radially oriented serpentine, but others lack this feature. Most clasts are dominated by serpentine or talc + magnetite. Matrix minerals are dominantly chlorite, tremolite, and talc + magnetite (p) serpentine. Whole-rock analyses of 3 serpentine-rich clasts are similar (mg# approximately 0.9, approximately 46 wt% SiO (sub 2) , approximately 42% wt% MgO, <3 wt% CaO, <1 wt% Al (sub 2) O (sub 3) on an anhydrous basis; up to 2000 ppm Ni; up to 2200 ppm Cr). These rocks represent serpentinized harzburgites, confirmed by normative mineralogy. Matrix compositions (2 samples) are much richer in Al (sub 2) O (sub 3) (11-20 wt%), reflecting higher amounts of chlorite, but are also ultramafic (34-44 wt% SiO (sub 2) , < or = 1200 ppm Ni, < or = 1500 ppm Cr). These rocks have been referred to as "orbicular serpentinite" in the past (including us: Garry & Owens, 1999, SE GSA abstract), and we tentatively interpreted them as metamorphosed orbicular ultramafic rocks. However, the clasts do not display concentric mineralogical zoning, and some lack an obvious outer shell. They superficially resemble examples of mantle xenoliths in alkali basalts, but an intraplate-setting is inappropriate here, as are the matrix compositions. Alternatively, these rocks bear some similarities to harzburgite clasts entrained in modern serpentinite mud volcanoes (e.g., Marianas and Izu-Bonin Forearcs). This interpretation is consistent with the convergent margin setting here, especially the location in a melange zone. The quasi-orbicular textures probably reflect metasomatic reaction zones between clasts and matrix during later metamorphism.

Samples (N = 155) were collected from ships' ballast tanks on two cruises in 2003, frozen and shipped to the laboratory. The stability of the fluorometer response over the analysis period was independently tracked using internal and external calibration factors which appear to rule out the fluorometer as the source of the changes. Six independent fluorescent components, consistent with humic/fulvic and protein-like dissolved materials, were first identified using parallel factors analysis (PARAFAC). Changes in their concentrations over time were investigated using random coefficients mixed regression models. Fluorescence by each component decreased apparently exponentially over time, with three humic-like components reduced to half- maximum fluorescence in 5-6 months. Protein-like fluorescent components and a single PAH-like component decreased more quickly, with half lives of 2-3 months. Rates of fluorescence loss by each component were similar regardless of the origin of the samples. Loss of fluorescence in dark-stored frozen samples is previously unreported and has not yet been reproduced under controlled conditions using seawater from other sources. A review of current literature suggests that CDOM samples are frequently assumed to remain stable for several months or longer under a range of storage temperatures. While it appears more usual for samples to remain stable, this research highlights the need to test assumptions regarding the stability of CDOM fluorescence signals from previously unstudied sources.

Here we sample all extant or recently extinct white-eye (Zosterops) taxa of the southwest Indian Ocean, combined with samples from all principal continental lineages. Results support a high dispersal capability, with at least two independent continental sources for white-eyes of the region. An early (within 1.8 million years ago) expansion into the Indian Ocean may have originated either from Asia or Africa; the three resulting lineages show a disparate distribution consistent with considerable extinction following their arrival. Africa is supported as the origin of a later expansion into the region (within 1.2 million years ago). On two islands, a pair of Zosterops species derived from independent immigrations into the Indian Ocean co-occur or may have formerly co-occurred, providing strong support for their origin by double-island colonization rather than within-island (sympatric or microallopatric) speciation. On Mauritius and La Reunion, phylogenetic placement of sympatric white-eyes allow us to rule out a scenario in which independent within-island speciation occurred on both islands; one of the species pairs must have arisen by double colonization, while the other pair is likely to have arisen by the same mechanism. Long-distance immigration therefore appears to be responsible for much of the region's white-eye diversity. Independent immigrations into the region have resulted in lineages with mutually exclusive distributions and it seems likely that competition with congeneric species, rather than arrival frequency, may limit present-day diversity.

OMI's daily global coverage and spatial resolution as high as 13x24 km provides a unique data set of these molecules for the study of air quality from space. We present the first study of global seasonal distributions of CHOCHO from space, derived from a year of OMI observations. CHOCHO distributions are compared to simultaneous retrievals of HCHO from OMI, providing a first indication of seasonally resolved ratios of these VOCs on a global scale. Satellite retrievals are compared to global simulations of HCHO and CHOCHO, based on current knowledge of sources and sinks, using the GEOS-Chem global chemistry and transport model. Formaldehyde is both directly emitted and also produced from the oxidation of many VOCs, notably biogenic isoprene, and is removed by photolysis and oxidation. Precursors of glyoxal include isoprene, monoterpenes, and aromatics from anthropogenic, biogenic, and biomass burning emissions; it is removed by photolysis, oxidation by OH, dry/wet deposition, and aerosol uptake. As a case study, satellite observations will also be compared to ground-based measurements taken during the Pearl River Delta 2006 field campaign near Guangzhou, China, where high glyoxal concentrations are frequently observed from space.

Manipulative experiments, analyses of existing communities and bioassays tested hypotheses that the relative dominances of these functional groups are mediated by two principal controlling factors: nutrients (i.e., bottom-up control) and herbivory (i.e., top-down control). The results show that reduced nutrients alone do not preclude fleshy algal growth when herbivory is low, and high herbivory alone does not prevent fleshy algal growth when nutrients are elevated. However, reduced nutrients in combination with high herbivory virtually eliminate all forms of fleshy micro- and macro-algae. The findings reveal considerable complexity in that increases in bottom-up nutrient controls and their interactions stimulate harmful fleshy algal blooms (that can alter the abundance patterns among functional groups, even under intense herbivory); conversely, elevated nutrients inhibit the growth of ecologically beneficial reef-building corals. The results show even further complexity in that nutrients also act directly as either limiting factors (e.g., physiological stresses) or as stimulatory mechanisms (e.g., growth enhancing factors), as well as functioning indirectly by influencing competitive outcomes. Herbivory directly reduces fleshy-algal biomass, which indirectly (via competitive release) favors the expansion of grazer-resistant reef-building corals and coralline algae. Because of the sensitive nature of direct/indirect and stimulating/limiting interacting factors, coral reefs are particularly vulnerable to anthropogenic reversal effects that decrease top-down controls and, concomitantly, increase bottom-up controls, dramatically altering ecosystem resiliencies.

In pairwise comparisons of genetic differentiation among demographic classes, only seedlings were significantly differentiated from the other diameter classes; F[sub]ST values ranged from 0.006 to 0.009. Furthermore, only seedlings showed homozygote excess suggesting biparental inbreeding in the large diameter reproductive adults. We found very low levels of relatedness in the first distance class of trees, 1-26 cm diameter (F[sub]ij = 0.011). However, there was a 5- to 10-fold rise in relatedness in the smallest distance class, from the smallest to the largest tree diameter classes (F[sub]ij = 0.110 for individuals > 56 cm diameter). A variety of non-mutually exclusive mechanisms have been invoked perviously to explain such a pattern, including natural selection, history, or nonequilibrium population dynamics. The long-term demographic data available for this species allow us to evaluate these mechanisms. Jacaranda is a fast-growing, light-demanding species with low recruitment rates and high mortality rates in the smaller diameter classes. It successfully regenerates only in large light gaps, which occur infrequently and stochastically in space and time. These factors contribute to the nonequilibrium population dynamics and observed low genetic structure in the small size classes. We conclude that the pattern of spatial genetic transitions in Jacaranda is consistent with overlapping related generations and strong but infrequent periods of high recruitment, followed by long periods of population decline.

Nine species in five genera were identified, including Careproctus melanurus, Careproctus ovigerus, Careproctus longifilis, Careproctus gilberti, Careproctus filamentosus, Osteodiscus cascadiae, Nectoliparis pelagicus, Paraliparis dactylosus and Rhinoliparis barbulifer. Voucher specimens were collected of all except C. melanurus, C. gilberti and C. filamentosus. In addition, individuals of the Paraliparis'rosaceus' species group were abundant but could not be identified to species. Many liparids were identified only to family, but an individual of a very distinctive unknown species, presumably undescribed, was videotaped. Relative abundance of C. melanurus was estimated, and several in situ snailfish behaviours are described for the first time.

In a community with a naturally discontinuous spatial structure, we asked (1) at what scale(s) nonrandom variation in species composition occurs and (2) at what scale(s) such variation is associated with spatial separation, indicative of dispersal limitation, and at what scale(s) variation is associated with environmental heterogeneity? We sampled 50 seeps (small wetlands) on five serpentine outcrops. Using a randomization model, we showed that additive beta diversity (a measure of community dissimilarity) was lower than random within seeps and higher than random among both seeps and outcrops. Using Mantel tests, we showed that plant community dissimilarity, in both the full seep assemblage as well as in a subset of seep endemics, at the two larger scales was associated with different forms of environmental heterogeneity and, at the largest scale, was also associated with geographic distance. We conclude that diversity in this system is shaped by multiple scales of heterogeneity and by dispersal limitation at the largest scale.

Species were selected for study based on their potential for use in reforestation projects in Panama. Seeds of 32, 29, and 33 species were dispersed during the dry (DS, January-March), early rainy (ERS, April-July), and late rainy (LRS, August-December) seasons, respectively. Seed mass was correlated with moisture content (MC) but not with dispersal time, and MC was lowest for seeds dispersed in the DS. Germination of nontreated seeds ranged from 0% (6 species) to 99% and was >=50% for 46 species. Seeds of Beilschmiedia pendula, Castilla elastica, Diphysa robinioides, Genipa americana, Hura crepitans, Inga spectabilis, Jacaranda copaia, Protium tenuifolium, Pseudobambox septenatum, and Trattinnickia aspera germinated >=85%. Fresh seeds of 49 (52.1%) of the 94 species that germinated were nondormant and 45 (47.9%) were dormant. Only 12 species had a median length of germination time (MLG)>120 days. MLG for seeds of species dispersed in the LRS was higher than that of those dispersed in the ERS or DS. Forty-eight species had uniform germination (standard deviation of germination time approximately equal to 14 days). Seed longevity ranged from 0.5 to 36 months, and long-lived (L-L) seeds tended to be larger than short-lived (S-L) or very short-lived (very S-L) ones, but not significantly so. MC increased significantly from L-L to very S-L seeds. The highest proportion of L-L seeds was dispersed in the DS and the lowest in the LRS. Results of this study are used to make recommendations for nursery production of tree seedlings to use in forest restoration projects.

AN - 68776222; 16906362 AB - This study compared algal palatability and chemical defenses from subtropical green algae that may use different types of defense systems that deter feeding by the rock-boring sea urchin Echinometra lucunter. The potential defense systems present include (1) the terpenoid caulerpenyne and its activated products from Caulerpa spp., and (2) dimethylsulfoniopropionate (DMSP)-related defenses in Ulva spp. Secondary metabolites from these chemical groups have been shown to deter feeding by various marine herbivores, including tropical and temperate sea urchins. Live algal multiple-choice feeding assays and assays incorporating algal extracts or isolated metabolites into an artificial diet were conducted. Several green algae, including Ulva lactuca, Caulerpa prolifera, and Cladophora sp., were unpalatable. Nonpolar extracts from U. lactuca deterred feeding, whereas nonpolar extracts from C. prolifera had no effect on feeding. Polar extracts from both species stimulated feeding. Caulerpenyne deterred feeding at approximately 4% dry mass; however, dimethyl sulfide and acrylic acid had no effect at natural and elevated concentrations. E. lucunter is more tolerant than other sea urchins to DMSP-related defenses and less tolerant to caulerpenyne than many reef fish. Understanding the chemical defenses of the algae tested in this study is important because they, and related species, frequently are invasive or form blooms, and can significantly modify marine ecosystems.

Andesites (56-61 wt.% SiO (sub 2) ) are minor in volume and a compositional gap of approximately 6 wt.% SiO (sub 2) exists between the andesites and the dacites. Most andesites contain sieve-textured plagioclase, and some dacites have resorbed plagioclase containing many glass inclusions. Some orthopyroxene phenocrysts in andesites and dacites have overgrowth rims with a high Ca content, a feature consistent with crystallization from a higher-temperature magma than their cores. Dacites, rhyolites and glasses in the matrix and plagioclases possess compositions similar to those of partial melts produced by dehydration-melting of calc-alkaline andesite (Tanzawa tonalite) at low pressure (3 kbar). Phenocryst assemblages of these andesites, dacites and rhyolites resemble restite phase assemblages of the dehydration melting. Prolonged fractionation or partial melting of basalts, in contrast, is untenable based on petrography and fractionation calculations. We suggest that the silicic magmas at Sumisu caldera volcano have been produced by dehydration melting of solidified calc-alkaline andesite (protolith) in the upper to middle crust, which segregated efficiently from restite crystals. In rare situations, reheating and en-mass remobilization permitted the same andesites to erupt as andesites (56-61 wt.% SiO (sub 2) ). Thus, Sumisu has a relatively narrow temperature difference (900-1100 degrees C) associated with a large compositional range (56-74 wt.% SiO (sub 2) ).

Ion microprobe analyses of olivine-hosted melt inclusions (MI) from the prehistoric ET3 (AR-19) and ET6 (AR-16) tephra layers reveal high concentrations of volatile species: approximately 1-4 wt.% H (sub 2) O, 50-300 ppm CO (sub 2) , and > 3000 ppm S and Cl. The MI with the highest water concentrations are the most mafic, and the dataset as a whole records a history of degassing coupled with fractionation and ascent from approximately 2 kbar to 0.2 kbar. Arenal MI form two groups based on their Al, CO (sub 2) and S contents. The ET3 high-Al MI were trapped at the highest pressure, are closest to equilibrium with their host olivines ( approximately Fo (sub 79) ), which are closest to equilibrium with the bulk-rock liquid. These MI are excellent candidates for Arenal parental liquids, and can generate most Arenal volcanic rock compositions by crystal accumulation (up to 30%), or crystal fractionation at a range of pressure (0.5-3 kb) and H (sub 2) O contents (0.5-3.5 wt.%). The new sulfur data reported here predict total sulfur output over the past approximately 30 years from bulk basaltic andesite liquid that matches well spectroscopic estimates, and resolves the previously noted imbalance. MI from different ET3 and ET6 samples show different F/Cl, while most trace element ratios show a limited range similar to that of the host rocks. The high water content (4 wt.% H (sub 2) O) of Arenal basaltic magma is somewhat surprising given the weak subduction signal recorded geochemically (e.g., low (super 10) Be and B). The Arenal MI data contribute to a positive correlation between primary water contents and Ba/La in Central American volcanoes, although further testing is required given the small number of data points, and the expectation that water and trace elements should have different sources in the subduction zone.

Here we describe, illustrate, and name variable features of the avian palatinum that we judge to be potentially important for phylogenetic inference. To standardize anatomical nomenclature, we introduce formal names (per ICAAN) and revise others for palatal features provisionally considered to be homologous among modern birds (Neornithes). The palatinum can-be divided topographically into four parts--pars maxillaris, pars choanalis, pars lateralis, and pars pterygoideus--each having variation in organization, function, and phylogenetic corollaries that facilitate comparisons within Neornithes and with Mesozoic allies. Emphasis on study of juvenile specimens of modern birds in which intact sutures are discernible revealed details in the structure of arcus pterygopalatinus and arcus pterygovomeralis that facilitated diagnosis of both palaeognathous and neognathous birds, and (within the latter) the Galloanserae and its sister-group, Neoaves. Articulatio vomeroparasphenoidalis may represent a synapomorphy of palaeognathous birds (ratites and tinamous). Although articulatio intrapterygoidea commonly is thought to provide the flexibility within arcus ptery-gopalatinus required for cranial kinesis in neognathous birds, we found that six patterns of articulations and flexible zones (zonae flexoriae) serve that function; these patterns are probably apomorphous, sometimes convergently, within Aves. Hesperornis apparently displays homoplasious flexibility within arcus pterygopalatinus. We found developmental evidence against paedomorphosis ("neoteny") as an explanation of certain distinguishing features of palaeognathous palates, and comparison with palatal remnants of Archaeopteryx, Gobipteryx, Hesperornis, and several nonavian theropods suggest plesiomorphy of other palaeognathous features. Reconsideration of "palaeognathous" characters found in adults of some neognathous taxa, previously explained as evolutionary reversals, led us to a variety of alternative hypotheses. We believe that analysis of individual characters within the avian palatinum and palatal skeleton holds significantly greater promise for phylogenetic and functional inferences than the continued use of the classical, composite palatal types--palaeognathous, schizognathous, desmognathous, and aegithognathous--for phylogenetic reconstructions.

The rare earth element (REE) and U/Th composition of fossil bones reflects associated pore water compositions during the period of recrystallisation. The REE composition of fossil bones is controlled by partitioning of REE between pore waters and particle surfaces, and the REE composition of fossil bones reflects the REE composition of pore waters which vary spatially and temporally. Light REE are preferentially sorped onto particle surfaces, thus the high La/Yb values seen in many bones from coastal marine and aeolian environments are best explained by release of REE from light REE-enriched particles to local pore waters and subsequent immobilisation in recrystallising bones. The REE compositions of bones recovered from pedogenically altered diatomite sediments of the Olorgesailie Formation of southern Kenya vary over spatial scales of less than 10 m. Location accounts for 48% of the observed variation in bone chemistry and bones recovered from eight discrete excavations within the same time-equivalent stratigraphic layer can be assigned to their excavation location with >70% accuracy based on a discriminant analysis of REE, U, and Th composition. Despite this within-layer variation, bones recovered from different stratigraphic horizons within the Olorgesailie Formation can also be distinguished on the basis of their trace element composition. Bones recovered from four stratigraphic horizons spanning ca. 0.5 million years were assigned to their correct stratigraphic layer with >90% accuracy. Where sedimentological conditions are favourable, the trace element composition of fossil bone may be used to test stratigraphic provenance and burial location in excavated bone with a temporal resolution of <10 ka and a spatial resolution of <10 m. The trace element composition of fossil bone may also be used to investigate the accumulation history of vertebrate assemblages and to reconstruct pore water variability across land surfaces.

Using tree-ring methods, we dated deadwood to AD 815-1350 and infer from death dates that the eruption occurred in late summer AD 1350. Based on wood anatomy, we identified deadwood species as Pinus albicaulis, P. monticola, P. lambertiana, P. contorta, P. jeffreyi, and Tsuga mertensiana. Only P. albicaulis grows at these elevations currently; P. lambertiana is not locally native. Using contemporary distributions of the species, we modeled paleoclimate during the time of sympatry to be significantly warmer (+3.2 degrees C annual minimum temperature) and slightly drier (-24 mm annual precipitation) than present, resembling values projected for California in the next 70-100 yr.

Because of their pressing conservation needs, we began studies to examine the membrane physiology and cryobiology of the mushroom coral, {\it Fungia scutaria}, with the future goal of conserving their germline cells in a genome resource bank. To cryopreserve cells effectively, some intracellular water must be removed and replaced with a cryoprotectant. The cryoprotectant reduces intracellular damage and stabilizes membranes. We determined {\it F. scutaria} sperm fell within the same morphological range as other anthozoan sperm (mean length = 56$\mu$m; mean head diameter = 2.5$\mu$m), and had a spontaneous ice nucleation temperature of -37.2+/-1.7 \deg C. When the sperm was exposed to the cryoprotectant, glycerol, it was toxic. However, glycerol was not toxic to the eggs. Two other cryoprotectants, dimethyl sulfoxide and propylene glycol, were non-toxic to the eggs and sperm. We used these non-toxic cryoprotectants to develop cryopreservation protocols that yielded both good morphology and excellent motility. However, these still need to be tested in extensive field fertilization assays. Unlike the sperm, {\it F. scutaria} larvae demonstrated a wide tolerance to cryoprotectants, including glycerol. Uptake of radiolabeled glycerol increased over time, suggesting that the larvae were permeable to exogenous glycerol. Parameter fitting of the {\it F. scutaria} larvae data yielded a water permeability ca. 2$\mu$m/min/atm and a cryoprotectant permeability = 2.3 x 10${-4}$ cm/min while modeling indicated that glycerol reached 90% of final concentration in the larvae within 25 mins. The spontaneous ice nucleation temperature for {\it F. scutaria} larvae in filtered seawater was -37.8 +/- 1.4 \deg C. However, when {\it F. scutaria} larvae were chilled from room temperature to -11\deg C at various rates (with no ice present), they exhibited 100% mortality. When rapidly cooled from room temperature to test temperatures, they showed damage below 10 \deg C. These data suggested that they were sensitive to both the rate of chilling and the absolute temperature. Further, these observations indicated that ultra-rapid cooling, called vitrification, may be the only means to successfully cryopreserve these organisms. In this process, no ice crystals form and the cells pass through the sensitive temperatures too quickly to suffer damage.

Among the most degraded reefs are those of the Caribbean, which have suffered an 80 percent decline in coral coverage over the last thirty years (Gardner et al. 2003). This research examines how anthropogenic stress affects the relationship between a coral and its associated microbial community. Coral associated bacteria are known to be diverse, abundant, and species-specific yet their role in coral health and immunity is largely unknown. In a series of experiments utilizing a custom designed culturing system (the AADAMS), we demonstrate that routinely measured aspects of water quality (nitrate, phosphate, ammonia) do not cause substantial coral mortality at environmentally relevant treatment levels. In contrast, dissolved organic carbon (DOC), which is rarely measured on reefs, does. Elevated DOC levels also accelerate the growth rate of bacteria living in the corals' surface mucopolysaccharide layer (SML) by an order of magnitude, suggesting that mortality occurs due to a disruption of the balance between the coral and its associated microbiota. Furthermore, we present data from White Band Disease type I (WBD I) transmission studies which reveal that WBD I is contagious and its transmission is likely influenced by anthropogenic stress. We also describe a new concept to exploit the convergence of modern high-resolution digital imaging, inexpensive computational power and mass storage, and advances in computer vision theory that can be used to create digital "expert systems". Our goal is to develop an effective digital imaging - computer vision system for automated reef structural ecological surveys that should allow more rapid quantification of reef health.

Sequencing of mitochondrial DNA in 20 reef fish morphospecies encountered on both sides of the barrier revealed cryptic speciation in two. Among the other 18 species only two showed significant differentiation (as revealed by haplotype networks and F sub(ST) statistics) between the eastern and the central Pacific. Coalescence analyses indicated that genetic similarity in the 18 truly transpacific species resulted from different combinations of ages of most recent invasion and of levels of recurrent gene flow, with estimated times of initial separation ranging from approximately 30000 to 1Myr (ago). There is no suggestion of simultaneous interruptions of gene flow among the species. Migration across the EPB was previously thought to be exclusively eastward, but our evidence showed two invasions from east to west and eight cases in which subsequent gene flow possibly proceeded in the same direction. Thus, the EPB is sporadically permeable to propagules originating on either side.

Overgrown 0.5-liter porous clay-pot diffusers ("mini-reefs" - following a decade of recruitment, colonization and competition) were utilized to evaluate protocols for studies of controlled nutrient enrichment on coral reefs. A commonly used fertilizer, Tree Food Stakes resulted in detrimental 11-fold and 20-fold decreases of fleshy algae and calcareous coralline algae, respectively, relative to the Control treatments; while blue-green algae (Cyanobacteria) became significantly (6 times) more abundant. Osmocote-filled mini-reefs showed no such negative differences in mortality from the Controls for any functional group. By avoiding the pitfalls of inappropriate sources of enrichment, insufficient durations of colonization/competition studies, suboptimal study areas and inadequate nutrient detection limits in future research, the potential to provide new insights into the nutrient status of coral reefs is greatly increased.

We used skeletochronological data on humerus diameter growth changes to estimate the age of North Pacific olive ridley seaturtles caught incidentally by pelagic longline fisheries operating near Hawaii and from dead turtles washed ashore on the main Hawaiian Islands. Two age estimation methods [ranking, correction factor (CF)] were used and yielded age estimates ranging from 5 to 38 and 7 to 24 years, respectively. Rank age-estimates are highly correlated (r = 0.93) with straight carapace length (SCL), CF age estimates are not (r = 0.62). We consider the CF age-estimates as biologically more plausible because of the disassociation of age and size. Using the CF age-estimates, we then estimate the median age at sexual maturity to be around 13 years old (mean carapace size c. 60 cm SCL) and found that somatic growth was negligible by 15 years of age. The expected age-specific growth rate function derived using numerical differentiation suggests at least one juvenile growth spurt at about 10-12 years of age when maximum age-specific growth rates, c. 5 cm SCL year super(-1), are apparent.

The species has experienced sustained evolutionary stasis for at least the past 400,000 yr, during which time there has been no perceptible change in skeletal morphology. The tortoise Hesperotestudo bermudae is known from a single fossil from interglacial period marine isotope stage (MIS) 9--approximately 300,000 yr ago. A viable population of tortoise on Bermuda could be reconciled with the geological record and the lack of any other fossils of the species to date if tortoises colonized the island at or after the end of the maximal sea-level rise of interglacial MIS 11, evolved during the single glacial episode of MIS 10, and become extinct as a result of the interglacial sea-level rise of MIS 9, a period of about 100,000 yr. Such rapid evolution and extinction has a close parallel in the giant tortoises of Aldabra Island in the Indian Ocean.

Because aboveground plant litterfall is an important source of nutrients in terrestrial ecosystems, any factor that alters plant litter quality can have large 'afterlife' effects on the decomposition rate of that litter and the subsequent rate of nutrient release. Two contrasting patterns emerge from the literature and are corroborated by our two experimental case studies. First, in evergreens, herbivory commonly results in premature leaf abscission, improved litter 'quality' and an acceleration of litter decomposition. Second, in deciduous trees, herbivory commonly results in the induction of secondary compounds that decelerates decomposition. We argue that these broad patterns reflect predictable differential responses to herbivores that can have important consequences for terrestrial nutrient cycling and productivity and that warrant more attention in the literature.

Analysis of these mtDNA sequences reveals that the Cuban and North American ivory bills, along with the imperial woodpecker (Campephilus imperialis) of Mexico, are a monophyletic group and are roughly equidistant genetically, suggesting each lineage may be a separate species. Application of both internal and external rate calibrations indicates that the three lineages split more than one million years ago, in the Mid-Pleistocene. We thus can exclude the hypothesis that Native Americans introduced North American ivory-billed woodpeckers to Cuba. Our sequences of all three woodpeckers also provide an important DNA barcoding resource for identification of non-invasive samples or remains of these critically endangered and charismatic woodpeckers.

To separate these factors, we sampled the lichenized Cladonia subtenuis and associated Asterochloris algae across a broad geographic range. We sampled 87 thalli across 11 sites using sequence data to test for fungal specificity (phylogenetic range of association) and selectivity (frequency of association), fungal reproductive mode, and geographic structure among populations. Permutation tests were used to examine symbiont transmission. Four associated algal clades were found. Analysis of molecular variation (amova) and partial Mantel tests suggested that the frequency of associated algal genotypes was significantly different among sites and habitats, but at random with respect to fungal genotype and clade. The apparent specificity for Clade II algae in the fungal species as a whole did not scale down to further within-species lineage-dependent specificity for particular algae. Fungal genotypes were not structured according to site and appeared to be recombining. We suggest that ecological specialization exists for a specific lichen partnership and a site, and that this selectivity is dynamic and environment-dependent. We present a working model combining algal availability, fungal specificity and selectivity, which maintains variation in symbiotic composition across landscapes.

This process has been extensively described and modelled, but as yet there has been no formal test of how the spatial patterns of deforested and fragmented areas change with the spatial scale of forest clearings. It was hypothesised that different land- use practices are driving small and large clearings, with small-scale cultivators often creating small, irregularly shaped clearings and large-scale ranchers and soy farmers creating larger, more regular-shaped clearings. To quantitatively test this hypothesis, Mandelbrot's theory of fractals was applied to deforested areas in the Brazilian Amazon to test for scale-invariance in deforestation patterns. The spatial pattern of deforestation differed between small and large clearings, with the former creating more complex landscapes and with a threshold occurring at c. 1200 ha in area. As a consequence, the sizes and shapes of forest clearings, and hence the relative vulnerability of the remaining forest to edge, area and isolation effects, may differ systematically between landscapes with different deforestation drivers. Further tests of this hypothesis are needed to assess its efficacy in other tropical landscapes and geographical locations.

We present a novel analysis of temporal polyethism in the ant Pheidole dentata, demonstrating that task attendance by minor workers does not shift among spatially associated sets of behaviors that minimally overlap but rather expands with age. Our results show that the number of tasks performed by older minors increases through the addition and retention of behaviors, with up to a sixfold increase in repertoire size from day 1 to day 20 of adult life. We also show that older minors respond to colony needs by performing significantly more brood care as its demand increases, indicating that they can quickly upregulate nursing according to labor requirements. This level of plasticity was absent in younger siblings. The breadth of responsiveness to task-related olfactory stimuli increased with age. In a binary choice test in which young and old minor workers could orient toward odorants from brood or food, older workers responded to both brood and food, whereas young workers responded only to brood. These dissimilar responses to stimuli associated with nursing and foraging indicate age-related differences in sensory ability and provide a physiological basis for the age-related repertoire expansion model. We discuss repertoire expansion in P. dentata in light of behavioral development and caste flexibility in ants.

Phylogenetic analysis of nuclear ribosomal ITS and chloroplast rps16 and trnL-F sequences revealed two highly distinct clades corresponding to EA and ENA. The divergence time between the intercontinental populations was estimated to be 3.68 plus or minus 2.25 to 5.23 plus or minus 1.37 million years ago (mya) based on combined chloroplast data using Bayesian and penalized likelihood methods. Phylogeographic and dispersal-vicariance (DIVA) analysis suggest a North American origin of Phryma and its migration into EA via the Bering land bridge. Multivariate analysis based on 23 quantitative morphological characters detected no geographic groups at the intercontinental level. The intercontinental populations of Phryma thus show distinct molecular divergence with little morphological differentiation. The discordance of the molecular and morphological patterns may be explained by morphological stasis due to ecological similarity in both continents. The divergence of Phryma from its close relatives in the Phrymaceae was estimated to be at least 32.32 plus or minus 4.46 to 49.35 plus or minus 3.18 mya.

We then compared the proportional representation of understory trees (1-2 cm dbh) among these classes. The understory of the three Asian sites was predominantly composed of the saplings of large-canopy trees whereas the African and American sites were more richly stocked with trees of the smaller SAM classes. Differences in class representation were related to taxonomic families that were present exclusively in one continent or another. Families found in the Asian plots but not in the American plot (e.g., Dipterocarpaceae, Fagaceae) were predominantly species of the largest SAM classes, whereas families exclusive to the American plots (e.g., Melastomataceae sensu stricto, Piperaceae, and Malvaceae [Bombacacoidea]) were predominantly species of small classes. The African plot was similar to Asia in the absence of those American families rich in understory species, while similar to America in lacking the Asian families rich in canopy species. The numerous understory species of Africa were chiefly derived from families shared with Asia and/or America. The ratio of saplings (1-2 cm dbh) to conspecific canopy trees (>40 cm dbh) was lower in American plots than in the Asian plots. Possible explanations for these differences include phenology, moisture and soil fertility regimes, phyletic constraints, and the role of early successional plants in forest development. These results demonstrate that tropical forests that appear similar in tree number, basal area, and the family taxonomy of canopy trees nonetheless differ in ecological structure in ways that may impact the ecology of pollinators, dispersers, and herbivores and might reflect fundamental differences in canopy tree regeneration.

Pollen, phytolith, and charcoal records identify the distribution and composition of tropical vegetation and fire patterns during the late Pleistocene, when they were significantly altered from today's, and earliest Holocene, when plant communities reassembled and interglacial representatives began to coalesce on the landscape. The significance of the environmental perturbations that occurred during the transition from the Pleistocene to the Holocene for human occupation of the lowland tropical forest and the geography and chronology of agricultural origins is discussed. Fire was employed by hunters and gatherers and farmers alike during the past 11,000 years as a primary tool of forest modification. The profound effects of an ancient pre-Columbian development of plant food production and, subsequently, slash and burn agriculture between ca. 10,000 BP and 4000 BP can be seen on lowland forests from Mexico to the Amazon Basin.

The current surge of renewed interest in LDD, motivated by growing recognition of its critical importance for natural populations and communities and for humanity, promises an improved, quantitatively derived understanding of LDD. To gain deep insights into the patterns, mechanisms, causes, and consequences of LDD, we must look beyond the standard dispersal vectors and the mean trend of the distribution of dispersal distances. "Nonstandard" mechanisms such as extreme climatic events and generalized LDD vectors seem to hold the greatest explanatory power for the drastic deviations from the mean trend, deviations that make the nearly impossible LDD a reality.

Because this lenticular claystone deposit records such a high diversity of contemporaneous species, it provides an exceptionally detailed view of their paleoecology and local paleoenvironment. In this study, we reexamined the entire Quarry 9 collection, totaling more than 3700 specimens, and developed a revised faunal list that was used to determine taxonomic and ecological diversities. Comprehensive abundance data were collected as well, revealing significant discrepancies between the most diverse and most abundant groups. Amphibious taxa (crocodilians and turtles) were very abundant, and seemed to fill an important ecological role as "connectors" between the terrestrial and aquatic food webs. In contrast, small terrestrial taxa (small theropods, mammals, and small reptiles) were very diverse, highlighting their central placement within the terrestrial food web. Lithologically and sedimentologically, the deposition of Quarry 9 occurred in a low-energy pond or swamp, an interpretation supported by the available taphonomic data.

We analyzed insect-feeding damage on 14,999 angiosperm leaves from 14 latest Cretaceous, Paleocene, and early Eocene sites in the western interior United States. Most Paleocene floras have low richness of plants and of insect damage. However, a low-diversity 64.4-million-year-old flora from southeastern Montana shows extremely high insect damage richness, especially of leaf mining, whereas an anomalously diverse 63.8-million-year-old flora from the Denver Basin shows little damage and virtually no specialized feeding. These findings reveal severely unbalanced food webs 1 to 2 million years after the end-Cretaceous extinction 65.5 million years ago.

Allanite occurs as cores in igneous epidote-clinozoisite and exhibits characteristic and consistent zoning patterns. REE-rich cores (All (sub 40-70) ) grade out towards epidote-clinozoisite with REE below electron microprobe detection limits. La, Ce and Pr contents are highest in the REE-rich cores of zoned crystals. Nd and Sm contents both initially increase as total REE decreases and are highest in intermediate zones. Y contents are generally low throughout, but tend to be highest in analyses with All (sub 5-20) . The zoning behavior exhibited by the allanite, specifically the rimward increases in Nd, Sm, and Y, cannot be accounted for by simple fractionation and are best explained by increases in allanite/melt partition coefficients (K (sub d) values) for these elements during crystallization. We propose that the variation in K (sub d) values reflects modification of the allanite structure with changing REE content. These modifications are manifested by changes in color, extinction, and pleochroism within the zoned crystals and include changes in unit-cell volume and dimensions. The changes in K (sub d) values are large enough to result in crossing REE patterns within single allanite crystals. Fractional crystallization of zoned allanite can have noticeable effects on LREE contents and La/Sm (and almost certainly La/Lu) in magmas. In the Bell Island Pluton, 80% of La, but <3% of Y is contained in allanite. Although some of the variation in the LREE chemistry of the pluton is attributable to statistical sampling error, much of it appears to reflect petrogenetic processes that controlled LREE abundance and, ultimately, allanite mode. One sample of Bell Island tonalite is depleted in LREE and has low La/Lu and La/Sm. These chemical features can be modeled by fractionation of zoned allanite.

However, new field surveys combined with shallow drilling along the coast between Kilwa and Lindi are beginning to resolve the depositional history and structural evolution of this region over the past 85 Ma. Here we present the first attempt to synthesize the results of these studies to provide a coherent sedimentological, litho- and sequence stratigraphic framework, including new geological maps, for the Upper Cretaceous and Paleogene of the coastal zone. Santonian to Oligocene sediments crop out along a broad coastal belt south of the Rufiji River from the Kilwa peninsula to Lindi Creek in southern Tanzania. During approximately 55 Ma, over 1 km of a broadly homogeneous, mid to outer shelf clay-dominated succession was deposited across the passive margin, which we define here as the Kilwa Group. This lies disconformably across the shelf on Albian marls and is itself unconformably overlain by shallow water Miocene clays and more recent limestones, sands and gravels. Four formations can be identified within the Kilwa Group on the basis of characteristic secondary lithologies and facies, described here for the first time; the Nangurukuru, Kivinje, Masoko and Pande Formations. These formations include conformable stratigraphic intervals through both the Paleocene-Eocene and Eocene-Oligocene boundaries. Within the Kilwa Group, 12 sequence stratigraphic cycles can be identified at present, demonstrating relatively uniform and continual subsidence across the margin from Santonian to Early Oligocene time. A further major bounding surface is present between the Upper Cretaceous and Paleogene, but this may become partly conformable in the Lindi area. Although the principal lithology in all formations is clay or claystone, there are more permeable intervals containing pervasive coarser siliciclastic sediments and these have yielded traces of crude oil which is likely to have migrated from lower in the succession. The Kilwa Group thus also provides important new evidence for petroleum play development in the southern coastal zone.

AN - 51081489; 2008-084179 AB - A detailed analysis of the reflectance spectrum of asteroid 3628 Boznemcova, previously identified as a possible ordinary chondrite parent body, indicates that its surface consists of an assemblage dominated by clinopyroxene and plagioclase feldspar. The clinopyroxene is Fe (sub 2+) -bearing (likely in the range Fs (sub approximately 10-20) ),with >90% of the Fe2+ being present in the M1 crystallographic site (spectral type A). The clinopyroxene:plagioclase feldspar ratio is between approximately 2 and 3 ( approximately 55-75% clinopyroxene, approximately 20-33% plagioclase feldspar). If olivine is present, the clinopyroxene: olivine ratio is > approximately 3 (<20% olivine). The derived mineralogy of Boznemcova is most similar, but not identical, to the known angrite meteorites. The data suggest that Boznemcova formed by melting and differentiation of an oxidized chondritic precursor and probably represents an unsampled angrite-like body.

Almost all angrites (e.g., D'Orbigny, Lewis Cliff [LEW] 86010, and Sahara 99555) are composed predominately of anorthite, Al-Ti diopside-hedenbergite, and Ca-rich olivine, except for the type specimen, Angra dos Reis, which is composed almost entirely of Al-Ti diopside-hedenbergite. D'Orbigny, LEW 86010, and Sahara 99555 also have spectral properties very different from Angra dos Reis. These newly measured angrites all have broad absorption features centered near 1 mu m with very weak to absent absorption bands at approximately 2 mu m, which is characteristic of some clinopyroxenes. The spectrum of Angra dos Reis has the characteristic 1 and 2 mu m features due to pyroxene. One asteroid, 3819 Robinson, has similar spectral properties to the newly measured angrites in the visible wavelength region, but does not appear to spectrally match these angrites in the near-infrared.

Intensive agricultural practices drive biodiversity loss with potentially drastic consequences for ecosystem services. To advance conservation and production goals, agricultural practices should be compatible with biodiversity. Traditional or less intensive systems (i.e. with fewer agrochemicals, less mechanisation, more crop species) such as shaded coffee and cacao agroforests are highlighted for their ability to provide a refuge for biodiversity and may also enhance certain ecosystem functions (i.e. predation). 2. Ants are an important predator group in tropical agroforestry systems. Generally, ant biodiversity declines with coffee and cacao intensification yet the literature lacks a summary of the known mechanisms for ant declines and how this diversity loss may affect the role of ants as predators. 3. Here, how shaded coffee and cacao agroforestry systems protect biodiversity and may preserve related ecosystem functions is discussed in the context of ants as predators. Specifically, the relationships between biodiversity and predation, links between agriculture and conservation, patterns and mechanisms for ant diversity loss with agricultural intensification, importance of ants as control agents of pests and fungal diseases, and whether ant diversity may influence the functional role of ants as predators are addressed. Furthermore, because of the importance of homopteran-tending by ants in the ecological and agricultural literature, as well as to the success of ants as predators, the costs and benefits of promoting ants in agroforests are discussed. 4. Especially where the diversity of ants and other predators is high, as in traditional agroforestry systems, both agroecosystem function and conservation goals will be advanced by biodiversity protection.

PAMOLARE I Training Package, Planning and Management of Lakes and Reservoirs: Models for Eutrophication Management. UNEP-DTIE-IETC and ILEC, 1091 Oroshimo- cho, Kusatsu, Shiga 525-0001, Japan], was developed for Lake Fure situated 12-17 km north of Copenhagen, Denmark. The model was calibrated and validated against two years data from 2001 and 2002, respectively. Furthermore, the model was applied for examining the effects of an ongoing restoration project in the lake by testing three different prognosis scenarios: (1) aeration of the hypolimnion, (2) biomanipulation by removing the trash fish from the lake, (3) two processes described in the two scenarios were applied simultaneously. The calibration yielded acceptable results with a standard deviation (S.D.) of less than 45% for the phytoplankton abundance considered as the most important state variable in the model. The validation results were acceptable for the key state variable, phytoplankton abundance, compared to the observations. Thus, the model was applied to set up prognoses and the results from the prognoses showed that a major improvement in the water quality of the lake might be expected with a significant reduction in the phytoplankton abundance and in the concentration of total phosphorus (TP) in 10 years as expected from the restoration project in the lake. Moreover, the model suggested that the combined application of biomanipulation and aeration practices described in Scenario 3 was the most effective among the three restoration scenarios tested, in obtaining a significant reduction in both phytoplankton abundance and the concentration of TP in the lake. The validation of prognoses is possible when data are available on the development of the lakes status at later stages of the restoration project and after. The lower confidence in data possibly resulted in the high discrepancy from the observations in the validation simulations for zooplankton, the peak values of cyanobacteria, and the timing of phytoplankton, zooplankton and cyanobacteria in the calibration and validation simulations. These have to be taken into account during evaluating the results from the model for the management of the lake. It is recommended that an improved predictive model based on the one presented in this paper is developed due to the explained limitations in the current model developed in this study. It is also suggested that such a model is incorporated into monitoring of the lakes status for a better-informed decision-making in the management of Lake Fure in the future.

Such patchy distributions more likely occur in disturbed habitats associated with lower ant diversity and resource availability than in forests. Yet, few studies have quantitatively examined these patchy patterns to statistically test if ants are non-randomly distributed or at what scale. Coffee agroecosystems form a gradient of management intensification along which vegetative complexity and ant diversity decline. Using field studies and a spatially explicit randomization model, I investigated ant patchiness in coffee agroecosystems in Chiapas, Mexico varying in management intensity to examine if: (1) coffee intensification affects occurrence of numerically dominant ants, (2) numerical dominants form statistically distinguishable single-species patches in coffee plants, (3) shade trees play a role in patch location, and (4) patch formation or size varies with management intensity. Coffee intensification correlated with lower occurrence frequency of numerically dominant species generally and of one of four taxa examined. All dominant ant species formed patches but only Azteca instabilis was patchy around shade trees. Ant patchiness did vary somewhat with spatial scale and with strata (within the coffee layer vs around shade trees). Patchiness, however, did not vary with management intensity. These results provide quantitative evidence that numerically dominant ants are patchy within the coffee layer at different scales and that shade tree location, but not coffee management intensity, may play a role in the formation of patchy distributions.

We detected puma on Barro Colorado Island (BCI) nearly every month during the study but never found evidence of jaguars (Panthera onca) at either site. Both ocelots and puma fed predominantly on mammalian prey, but consumed a diversity of species. Collared peccaries (Pecari tajacu) and Central American red brocket (Mazama temama) were the most important food items for puma, whereas Central American agoutis (Dasyprocta punctata) and sloths (Choloepus hoffmanni and Bradypus variegatus) were the most important for ocelots. Considerable overlap in diet was found between populations and species, but the diet of puma on BCI was significantly different from the 2 ocelot populations in containing more large prey, suggesting that dietary differences between these predator species are chiefly related to their relative body size. Comparing across larger scales, both populations of ocelots in our study ate larger prey than elsewhere in their range, suggesting that their fundamental niche includes more medium-sized prey than their realized niche in other sites. Puma on BCI ate proportionally more peccaries and deer than in most other populations. These unusual diets in the wake of a recent decline or local extinction of jaguars are consistent with a prey shift in response to competitive release.

Objectives were to characterize semen osmolality and assess the influence of two media at various osmolalities on sperm viability. We examined the influence of Ham's F10 +Hepes medium (H) at 270, 400, 500 or 700mOsm (adjusted with sucrose, a nonpermeating cryoprotectant) and TEST Yolk Buffer (TYB) with 0% (300mOsm) versus 4% (900mOsm) glycerol (a permeating cryoprotectant). Electroejaculates (n=16) were assessed for osmolality using a vapor pressure osmometer. For media comparison, semen (n=5) was collected in TYB 0%, split into six aliquots, and diluted in H270, H400, H500, H700, and TYB 0% or TYB 4%. Each sample was centrifuged (300g, 8min), resuspended in respective medium, and maintained at 37 super(o)C for 3h. Sperm motility and forward progression were monitored every 30min for 3h post-washing. Acrosomal integrity was monitored at 0 and 60min post-washing. Results demonstrated that black-footed ferret semen has a comparatively high osmolality (mean+/-SEM, 513.1+/-32.6mOsm; range, 366-791mOsm). Ferret spermatozoa were sensitive to hyperosmotic stress. Specifically, sperm motility was more susceptible (P0.05) by hypotonic solutions. Exposure to TYB 4% glycerol retained more (P<0.01) sperm motility than a hyperosmotic Ham's (700mOsm). These findings will guide the eventual development of assisted breeding with cryopreserved sperm contributing to genetic management of this rare species.

In the rainforests of southern Gabon, we compared abundances of larger (>1 kg) mammal species at varying distances from forest roads and between hunted and unhunted treatments (comparing a 130-km[super]2 oil concession that was almost entirely protected from hunting with nearby areas outside the concession that had moderate hunting pressure). At each of 12 study sites that were evenly divided between hunted and unhunted areas, we established standardized 1-km transects at five distances (50, 300, 600, 900, and 1200 m) from an unpaved road, and then repeatedly surveyed mammals during the 2004 dry and wet seasons. Hunting had the greatest impact on duikers (Cephalophus spp.), forest buffalo (Syncerus caffer nanus), and red river hogs (Potamochoerus porcus), which declined in abundance outside the oil concession, and lesser effects on lowland gorillas (Gorilla gorilla gorilla) and carnivores. Roads depressed abundances of duikers, sitatungas (Tragelaphus spekei gratus), and forest elephants (Loxondonta africana cyclotis), with avoidance of roads being stronger outside than inside the concession. Five monkey species showed little response to roads or hunting, whereas some rodents and pangolins increased in abundance outside the concession, possibly in response to greater forest disturbance. Our findings suggest that even moderate hunting pressure can markedly alter the structure of mammal communities in central Africa. Roads had the greatest impacts on large and small ungulates, with the magnitude of road avoidance increasing with local hunting pressure.Original Abstract: La expansion de carreteras asociada con incrementos en la presion de caceria son una amenaza creciente para la vida silvestre tropical Africana. En los bosques lluviosos del sur de Gabon, comparamos las abundancias de especies de mamiferos mayores (>1 kg) a diferentes distancias de las carreteras y entre tratamientos con y sin caceria (comparamos una concesion petrolera de 130 km super(2)que estaba casi totalmente protegida de la caza con areas cercanas afuera de la concesion que tenian presion de caza moderada). En cada uno de los 12 sitios que estaban repartidos equitativamente en areas con caza y sin caza, establecimos transectos estandarizados de 1 km a cinco distancias (50, 300, 600 900 years 1200 m) de un camino no pavimentado, y muestreamos mamiferos repetidamente durante las estaciones seca y lluviosa de 2004.La caceria tuvo el mayor impacto sobre duikers (ephalophus spp.), bufalo de bosque (Syncerus caffer nanus) y Potamochoerus porcus, cuya abundancia declino afuera de la concesion petrolera, y menos efectos sobre gorilas (Gorilla gorilla gorilla) y carnivoros. Los caminos deprimieron la abundancia de duikers, sitatungas (Tragelaphus spekei gratus) y elefantes (Loxondonta africana cyclotis), la evasion de caminos fue mayor afuera que adentro de la concesion. Cinco especies de monos no mostraron respuesta a los caminos o a la caceria, mientras que la abundancia de algunos roedores y pangolines aumento afuera de la concesion, posiblemente en respuesta a una mayor perturbacion del bosque. Nuestros resultados sugieren que aun la caceria moderada puede alterar significativamente la estructura de comunidades de mamiferos en Africa central. Las carreteras tuvieron los mayores impactos sobres ungulados grandes y pequenos, la magnitud de la evasion de caminos aumento con la presion de caceria local.

Using an experimental site at La Selva Biological Station, Costa Rica, we examined whether plant diversity, plant community composition, and season influenced microbial communities. We also determined whether soil characteristics were related to differences in microbial communities. Phospholipid fatty acid (PLFA) composition revealed that microbial community composition differed across a plant diversity gradient (plots contained 1, 3, 5, or over 25 species). Plant species identity also was a factor influencing microbial community composition; PLFA composition significantly varied among monocultures, and among three-species combinations that differed in plant species composition. Differences among treatments within each of these comparisons were apparent in all four sampling dates of the study. There was no consistent shift in microbial community composition between wet and dry seasons, although we did see significant changes over time. Of all measured soil characteristics, soil C/N was most often associated with changes in microbial community composition across treatment groups. Our findings provide evidence for human alteration of soil microbial communities via the alteration of plant community composition and diversity and that such changes are mediated in part by changes in soil carbon quality.

Selection on young leaves has led to diverse forms of defense chemical expression. Though most allelochemicals are secondary metabolites, allelochemic function for a primary metabolite remains a possibility. We recently observed this phenomenon in the young leaves of Inga umbellifera, which accumulate the protein amino acid l-tyrosine to very high levels. We isolated l-tyrosine from young leaves of trees in Panama and characterized it using spectroscopic and chemical means. We chromatographically quantified leaf l-tyrosine levels across a range of developmental stages, showing that it was present in the youngest leaves and that its concentration increased throughout the period of expansion, reaching an average maximum of ca 10% of leaf dry mass in late-stage young leaves. This chemical phenotype was seen to be highly leaf-age specific: Free tyrosine was only present in mature leaves at very low levels. In bioassays with larvae of the noctuid moth H. virescens, l-tyrosine proved to be a potent growth inhibitor when added to artificial diet at 10% of dry mass. This suggests that a rarely observed defense strategy occurs in young I. umbellifera leaves, a hyper-produced primary metabolite functioning as an allelochemical.

Senescent ectomycorrhizal roots represent a large input of carbon into soils, but their fate remains unknown. Here, we present the surprising result that, despite much higher nitrogen concentrations, roots colonized by ectomycorrhizal (EM) fungi lost only one-third as much carbon as non-mycorrhizal roots after 2 years of decomposition in a pinon pine (Pinus edulis) woodland. Experimentally excluding live mycorrhizal hyphae from litter, we found that live mycorrhizal hyphae may alter nitrogen dynamics, but the afterlife (litter-mediated) effects of EM fungi outweigh the influences of live fungi on root decomposition. Our findings indicate that a shift in plant allocation to mycorrhizal fungi could promote carbon accumulation in soil by this pathway. Furthermore, EM litters could directly contribute to the process of stable soil organic matter formation, a mechanism that has eluded soil scientists.

Journal of Paleontology. 80, 245-263.] from the Gulf of Panama are observed to separate into viable fragments without external force. The process, termed autofragmentation, involves the development of distinctive morphologies designed to assist in colony division. Culturing C. exfragminis shows that fragments that are a consequence of autofragmentation are significantly better able to regenerate than fragments originating from mechanical fragmentation. However, the relative importance of auto- versus mechanical fragmentation in natural populations remains unknown. Autofragmentation in C. exfragminis is found to be stimulated by cooling waters, and analysis of growth in natural populations demonstrates that colonies undergo periodic fragmentation coincident with lowered water temperatures during seasonal upwelling in the Gulf of Panama. These observations suggest that C. exfragminis uses the drop in temperature that occurs during upwelling as a cue to indicate times of increased food availability which may assist in the successful regeneration of fragments. These results are discussed in the context of the morphological, ecological and evolutionary significance of autofragmentation as a method of asexual propagation in cupuladriids.

6970659 AB - Most ecological hypotheses about species coexistence hinge on species differences, but quantifying trait differences across species in diverse communities is often unfeasible. We examined the variation of demographic traits using a global tropical forest data set covering 4500 species in 10 large-scale tree inventories. With a hierarchical Bayesian approach, we quantified the distribution of mortality and growth rates of all tree species at each site. This allowed us to test the prediction that demographic differences facilitate species richness, as suggested by the theory that a tradeoff between high growth and high survival allows species to coexist. Contrary to the prediction, the most diverse forests had the least demographic variation. Although demographic differences may foster coexistence, they do not explain any of the 16-fold variation in tree species richness observed across the tropics.

AN - 68069739; 16644003 AB - Teratospermia (production of >60% morphologically abnormal sperm/ejaculate) is relatively common among various species in the family Felidae, which is comprised of 37 species. Over two decades of research in this area have produced a significant understanding of the phenotypic expression, its impacts on sperm function and etiology. There is good evidence suggesting that a reduction in genetic diversity contributes to this phenomenon. Results to date demonstrate that spermatozoa from teratospermic donors are compromised in the ability to undergo capacitation and the acrosome reaction, penetrate the zona-pellucida, fertilize conspecific oocytes and survive cryopreservation. Recent studies also reveal abnormalities in chromatin integrity in sperm from teratospermic donors, which, interestingly, fails to impact fertilization or embryo development after intracytoplasmic sperm injection. Through planned inbreeding studies, we now have established that teratospermic cats also produce more spermatozoa by virtue of more sperm producing tissue, more germ cells per Sertoli cell and reduced germ cell loss during spermatogenesis. Overall, it now is clear that gain in sperm quantity is achieved at the expense of sperm quality, suggesting an extensive disruption of normal testicular function in teratospermic donors. Preliminary studies on testicular gene expression in teratospermic cats have also revealed abnormal expression patterns. These findings have markedly increased our understanding of testis biology in the teratospermic donor and reaffirm the value of cats, including wild species, as models for studying novel regulatory mechanisms controlling spermatogenesis and spermiogenesis.

Scanning electron microscope (SEM) and cathodoluminescence (CL) petrography of jadeitite samples from several major occurrences [in Burma (Myanmar), Guatemala, Japan, Kazakhstan, and the U.S.A.] show that grains were deposited from fluids. Jadeite grain compositions indicate these fluid compositions changed with time. CL imagery guided the acquisition of oxygen-isotope and trace-element analyses with the ion microprobe. Jadeite grains in each rock grew in cycles that began with red- and/or blue-luminescent and ended with green-luminescent zones. The CL images were used to order the data into crystallization sequences. These data and electron-microprobe, major-element analyses document the association of green CL with increases in Ca, Mg, and Cr: (1) toward grain exteriors; (2) in fine-grained matrix around porphyroblasts; (3) in shear zones that cut grains; (4) in former open spaces now filled with jadeite; or (5) in veins. Abundances of many trace elements are greater in green-CL jadeitite compared with the red- or blue-CL zones. Some of these elements--in particular Li, Rb, Sr, Ti, Hf, Zr, Y, and REE--are unlikely to have been derived from serpentinite. Although crystal-chemical effects may explain some of the trace-element systematics (e.g., preferential incorporation of REE into Ca-richer jadeite), some kinetic control is suggested by sector-zoned, rhythmically zoned grains. The oxygen-isotope data suggest that jadeitite-depositing fluids either had multiple sources or evolved in composition along their flow paths (or both).

It is most similar to the Yellow-crowned Night-Heron N. violacea but differs in having a shorter and much heavier bill, a much more massive cranium, and more robust hindlimbs. Early historical accounts contain descriptions of what is undoubtedly this species, which was presumably exterminated subsequent to human colonization of Bermuda. The cranial and hindlimb specializations of the new species appear to be adaptations for feeding terrestrially on land crabs.

In a field season in 2003, a total of five sites was drilled (mostly using continuous coring) by the Tanzania Drilling Project for paleoclimate studies. The sediments are predominantly marine clays and claystones deposited in an outer shelf or slope environment and often contain excellently preserved microfossils suitable for geochemical analysis. The studies reported here include summaries of the lithostratigraphy, biostratigraphy (planktonic foraminifers, calcareous nannofossils, benthic foraminifers, and palynology) and organic geochemistry. TDP Site 6 was drilled near Kilwa Masoko (UTM 37L 555752, 9014922), 350m to the south-east of a previous site, TDP Site 1. The top 59.58m, which was mostly drilled without coring, consists of an Oligocene clay formation belonging to nannofossil Zone NP23. The rest of the hole, to a total depth of 61.25m, consists of a fault zone in which the Oligocene sediments are intermixed with middle Eocene clays of planktonic foraminifer Zone E9 and nannofossil Subzone NP15b. TDP Site 7 consists of two holes (Hole TDP7A: UTM 37L 547126, 9030142; Hole TDP7B: UTM 37L 0547130, 9030140) drilled just 5m apart at Kwamatola, a creek to the south of Kilwa Kivinje. Underneath approximately 20m of unconsolidated sands and gravels, claystones and siltstones were recovered to a total depth of 128.00m. The site spans lower Eocene planktonic foraminifer Zones E1, E2 and E3 and nannofossil Subzones NP 9b and NP10. The bottom of Hole TDP7B approaches the Paleocene-Eocene boundary but no unambiguously Paleocene sediments were recovered. TDP Site 8 was drilled to the south-east of Singino Hill (UTM 37L 548033, 9025811). Below a covering of surface gravels, it yielded predominantly dark greenish-gray claystones to a total depth of 22.95m. The sediments are from the lower Eocene and span the boundary between planktonic foraminifer Zones E3 and E4 and fall within nannofossil Zone NP10. TDP Site 9 was drilled near Nangurukuru junction (UTM 37L 538987, 9027049). It yielded predominantly dark greenish-gray siltstones to a total depth of 88.80m. Thin siliciclastic beds with trace fossils of the Nereites ichnofacies are common in the lower third of the site. These sediments span the Campanian-Maastrichtian stage boundary and are assigned to the Globotruncanella havanensis to Gansserina gansseri planktonic foraminifer zones and nannofossil Subzones UC15e (super TP) to UC17. TDP Site 10 was drilled to the west of Singino Hill, adjacent to the main Kilwa road (UTM 37L 0541243, 9028791). Below a superficial covering of gravel, it yielded predominantly dark greenish-gray silty claystones to a total depth of 100.80m. These sediments are assigned to Paleocene planktonic foraminifer Zone P4c-P5 and nannofossil Subzone NP9b. Organic geochemical analyses from all the sites revealed biomarkers of predominantly terrestrial origin and collectively indicate an unusually low degree of thermal maturity for the area, suggesting shallow maximum burial depths. Traces of migrated hydrocarbons were found in TDP Sites 7 and 10. Abstract Copyright (2006) Elsevier, B.V.

In postcolonial Mali, youth festivals and the National Museum are important sites for constructing a national culture. Through the use of different media, each site has marshaled a constellation of historical memories, symbolic forms, and cultural practices in the service of this nationalistic project.

As one of the few MSA faunal assemblages from East Africa subject to detailed analysis, it provides rare insight into the foraging behavior of the early modern humans in this region. The MSA fauna include taxa that were not historically present in the area, with the occurrence of reduncines and alcelaphines indicating widespread grasslands and proximity to a perennial source of water. The faunal analysis examined several lines of evidence, including breakage patterns, surface modification, and skeletal-element representation. By incorporating comparisons with multiple actualistic data sets, the analysis of the assemblage demonstrates that, while the influence of carnivores and other biotic agents was evident, the faunal remains were accumulated primarily by hominid activity. The skeletal-element representation at Porc-Epic includes an abundance of high utility bones, in contrast to the predominance of ''head-and-foot'' elements documented at other MSA and Middle Paleolithic (MP) sites. The MSA occupants of Porc-Epic effectively exploited a wide range of prey with more emphasis on small- and medium-sized mammals.

Using experimental litter removal and litter addition treatments, we investigated the effects of increased and decreased litterfall on early-stage litter decomposition and the abundance of meso-arthropods in a moist tropical forest. Litterbags containing freshly fallen leaves of Cecropia insignis (above and below the litter on the forest floor, and with and without fungicide) and Simarouba amara, or untreated birch wood (Betula sp.) were placed in either (1) plots where all litterfall was removed monthly (L-); (2) plots where litterfall was doubled monthly (L+), or (3) control plots (CT). Litter removal significantly slowed decomposition of both species and reduced the abundance of meso-arthropods on Simarouba litter. The fungicide treatment did not reduce apparent mass loss of Cecropia leaves. The litter addition treatment accelerated the decay of birch wood, probably because of increased nutrient availability from the extra litter; but there was no change in leaf-litter decomposition or meso-arthropod abundance in the L+ treatment. After 68 days, the concentrations of nitrogen, phosphorus, potassium, and magnesium in partially decomposed Cecropia litter were higher in the L+ treatment and lower in the L- treatment. The accumulation of phosphorus and nitrogen was greater in the litter in L+ plots and lower in the L- plots while the release of potassium and magnesium from decomposing litter was lower in the L+ treatment and greater in the L- plots. Thus, differences in the quantity of litterfall affect decomposition with consequences for carbon and nutrient storage and cycling.

As one of East Africa's premier tourist attractions, it is also a major source of foreign exchange for Tanzania. This paper reports the decline of populations of wildebeest, Thomson's and Grant's gazelles since the mid-1980s and the rise to dominance of the buffalo, the results of research carried out from 1996 to 2000 on the Crater ungulates, and discusses natural and anthropogenic factors that may be linked to the population changes. Samples comparing young:adult female ratios in Ngorongoro and Serengeti populations indicated higher survival rates of Crater wildebeest and zebra young, and lower survival rates of Thomson's gazelle. The possibility that predation by lions and spotted hyenas was responsible for reductions in the ungulate populations is belied by corresponding declines in the number of predators. Further research in the Ngorongoro Conservation Area is urgently needed to increase understanding of this complex ecosystem and promote effective stewardship, not only of Ngorongoro Crater but of the Serengeti ecosystem, of which the NCA is an integral part, comprising an International Biosphere Reserve.

AN - 67965779; 16580745 AB - An unprecedented bloom of the cyanobacterium Microcystis aeruginosa Kütz. occurred in the St. Lucie Estuary, FL in the summer of 2005. Samples were analyzed for toxicity by ELISA and by use of the polymerase chain reaction (PCR) with specific oligonucleotide primers for the mcyB gene that has previously been correlated with the biosynthesis of toxic microcystins. Despite the fact that secreted toxin levels were relatively low in dense natural assemblages (3.5 microg l(-1)), detectable toxin levels increased by 90% when M. aeruginosa was stressed by an increase in salinity, physical injury, application of the chemical herbicide paraquat, or UV irradiation. The application of the same stressors caused a three-fold increase in the production of H(2)O(2) when compared to non-stressed cells. The application of micromolar concentrations of H(2)O(2) induced programmed cell death (PCD) as measured by a caspase protease assay. Catalase was capable of inhibiting PCD, implicating H(2)O(2) as the inducing oxidative species. Our results indicate that physical stressors induce oxidative stress, which results in PCD and a concomitant release of toxin into the surrounding media. Remediation strategies that induce cellular stress should be approached with caution since these protocols are capable of releasing elevated levels of microcystins into the environment.

AN - 57678478; 458355 AB - Examines the change in citation behaviour in astronomy and physics since the introduction of the arXiv e-print repository at Cornell University (http://arxiv.org/). It has been observed in a number of studies that papers that initially appear as arXiv e-prints get cited more than papers that do not. Using the citation statistics from the NASA-Smithsonian Astrophysics Data System (ADS), data is provided that confirms the findings from these other studies and allows an examination of the average citation rate to e-printed papers in the Astrophysical Journal, and shows that for a number of major astronomy and physics periodicals, the most important papers are submitted to the arXiv e-print repository first. The study focused on showing that there is a significant difference between papers that appear as arXiv e-prints and papers that do not and was limited to an analysis of four major astronomy journals (Astrophysical Journal (including Letters and Supplement Series), Monthly Notices of the Royal Astronomical Society, Astronomy and Astrophysics, Proceedings of the Astronomical Society of the Pacific) and two physics journals (Physical Review, Nuclear Physics). A major difference was found between the normalized citation rate for papers from the pre-arXiv era and papers that have been offered as e-prints in the arXiv repository. Furthermore, based on a dataset of the Astrophysical Journal in the periods of 1985 through 1987 and 1997 through 1999, the study followed the citations for traditionally published papers and e-printed papers. The paper formulates these three effects in three postulates and then continues to test these postulates on data taken from the Astrophysics Data System and the arXiv. These postulates are: the Open Access Postulate (OA), where because of free, unrestricted access, papers are read more easily and therefore get cited more frequently; Early Access Postulate (EA), where papers offered as e-print are available sooner and therefore gain primacy and additional time in press, and therefore they get cited more often; and Self-selection Bias Postulate (SB), where the most important and therefore most citable papers are posted on the Internet.

However, vesicular lava flows are unlikely on small, airless bodies such as asteroids. To unravel the origin of these rocks, we analyzed vesicle sizes and abundances for two angrites and two eucrites using high-resolution X-ray computed tomography and conducted numerical modeling of bubble formation in a dike of ascending magma. Modeling results indicate that thin (<30 cm wide) dikes are trapped at approximately 5 km depth where approximately 75 ppm of CO and CO (sub 2) contribute equally to vesicle formation. Vesicular eucrites were metamorphosed in this deep-seated environment, the gas was lost, and they were excavated by impacts.

Two sinuous channel segments south of Abu Qir Bay are observed on a radar image: a more sinuous trace (36 km in length) west of Idku lagoon, and an eastern one ( approximately 20 km), reaching the lagoon's southeast corner. Sediment cores recovered along channel traces show sand-rich deposits (to >4 m thick) beneath the surface, in contrast with silty muds in areas away from channels. Historic and archaeological findings indicate that the Ptolemaic Roman city of Schedia once lay directly along the Canopic that channeled water from the 3rd to 2nd centuries B.C. until approximately 5th century A.D., after which Nile water was displaced to the east via Bolbitic and, later, Rosetta branches. Identification of buried, but well-defined, Canopic channels provides baselines for renewed archaeological exploration in this delta sector. Abstract Copyright (2006), Wiley Periodicals, Inc.

The study of these samples, using powerful analytical instrumentation, provides a basis for understanding aqueous activity on Mars. Although most analyses are at the scale of microns, the conclusions reached have important implications for large-scale aqueous processes. Secondary minerals, such as clays, salts, and carbonates, are present at some level in all Martian meteorite subtypes and are especially important in the nakhlites and ALH84001. Light element stable isotope analyses show evidence for mixing between atmosphere and magmatic fluids into a crustal reservoir, and that this crustal water was not in equilibrium with the host rocks. The mineralogical and isotopic data present a fairly consistent picture of the aqueous history of Mars: low levels of aqueous alteration are generally present but extensive aqueous processes are probably limited in space and time.

Geodetic evidence is summarized here which indicates a coherent sub-continental-scale change in tectonic velocity along a diffuse approximately 1000 km wide deformation zone at this plate boundary zone. Velocities in the region have not been constant, the western sites have slowed with a resulting eastward position deviation. Changes in site velocity define a sharp boundary near the centre of the Basin and Range Province approximately // the N-NW relative plate motion vector. From late 1999 velocity slowed to the W of this boundary relative to sites E of it by approximately 1 mm/yr. Sites near Great Salt Lake show large deviations due mainly to changes in lake level and ?hydrological loading. Relatively rapid deformation from 2003-2004 is interpreted to be the result of magma injection into the lowest crust beneath Lake Tahoe. Relative velocities for 2002 were mainly < 1 mm/yr with little regional coherence. During 2003 an apparent NE velocity change occurred of approximately 9mm/yr.

Because of this, we began cryobiological studies on the sperm of the mushroom coral, Fungia scutaria. We determined that F. scutaria sperm had a mean length of 56 mu m and head diameter of 2.5 mu m, and a mean spontaneous ice nucleation temperature of -37.2+ /-1.7 super(o)C. When the sperm were exposed to the cryoprotectant glycerol for 5 or 20min (at 10% v/v), no fertilized larvae were produced. However, when sperm were exposed for 20min to propylene glycol (10% v/v), fertilizations were produced at the same rate as untreated control eggs and sperm (P>0.05), but slightly less for dimethyl sulfoxide (10% v/v) (P95%) for coral sperm.

We hypothesized that short dry spells during the wet season are a significant source of mortality for the newly emerging seedlings of pioneer species that recruit in treefall gaps in tropical forests. An analysis of a 49-year rainfall record for three forests across a rainfall gradient in central Panama confirmed that dry spells of greater than or equal to 10 days during the wet season occur on average once a year in a deciduous forest, and once every other year in a semi-deciduous moist and an evergreen wet forest. The effect of wet season dry spells on the recruitment of pioneers was investigated by comparing seedling survival in rain-protected dry plots and irrigated control plots in four large artificially created treefall gaps in a semi-deciduous tropical forest. In rain-protected plots surface soil layers dried rapidly, leading to a strong gradient in water potential within the upper 10 cm of soil. Seedling survival for six pioneer species was significantly lower in rain-protected than in irrigated control plots after only 4 days. The strength of the irrigation effect differed among species, and first became apparent 3-10 days after treatments started. Root allocation patterns were significantly, or marginally significantly, different between species and between two groups of larger and smaller seeded species. However, they were not correlated with seedling drought sensitivity, suggesting allocation is not a key trait for drought sensitivity in pioneer seedlings. Our data provide strong evidence that short dry spells in the wet season differentially affect seedling survivorship of pioneer species, and may therefore have important implications to seedling demography and community dynamics.

Changes in pollen production could influence population dynamics and is likely to have important consequences for human health. This is the first study to evaluate pollen production by forest trees in response to rising atmospheric CO sub(2). Our research objective was to quantify pollen production by Loblolly Pine (Pinus taeda L.) trees growing in elevated CO sub(2) (ambient + 200 mu l l super(-1)) since 1996. Trees grown in high-CO sub(2) plots first began producing pollen while younger and at smaller sizes relative to ambient-grown trees. Pollen cone and airborne pollen grain abundances were significantly greater in the fumigated stands. We conclude that the greater number of mature trees in high-CO sub(2) plots resulted in greater pollen production at the stand level. Precocious pollen production has important implications for fertilization and pollen dispersal from young, dense stands. Increasing levels of airborne pollen raise concerns for escalating rates of human respiratory disease.

AN - 19290512; 6964835 AB - We tested the hypothesis that malarial parasites (Plasmodium and Haemoproteus) of black-throated blue warblers (Dendroica caerulescens) provide sufficient geographical signal to track population movements between the warbler's breeding and wintering habitats in North America. Our results from 1083 warblers sampled across the species' breeding range indicate that parasite lineages are geographically widespread and do not provide site-specific information. The wide distribution of malarial parasites probably reflects postnatal dispersal of their hosts as well as mixing of breeding populations on the wintering range. When compared to geographically structured parasites of sedentary Caribbean songbirds, patterns of malarial infections in black-throated blue warblers suggest that host-malaria dynamics of migratory and sedentary bird populations may be subject to contrasting selection pressures.

Consequently, many previous aquatic ecotoxicology experiments have been limited in their number of replicates and maintained in one or a few experimental aquaria, with only a limited number of stressors tested in each experiment. Here we describe a modular system that overcomes many of the difficulties of maintaining large numbers of sensitive aquatic organisms in separate containers, and allows testing of a large suite of stressors in each experiment. The AADAMS (aquatic automated dosing and maintenance system) allows testing of 40 independent stressors with 10 independent replicates per stressor (400 individuals total). The AADAMS provides surge and regular water changes simultaneously with accurate dosing via Venturi valves. In a series of experiments over a 1-year period, the AADAMS was used to test the effects of various factors affecting water quality on Caribbean coral reefs. Roofing tar and road asphalt were two of the most damaging pollutants tested, with LD sub(50) values (lethal dose that killed 50% of the corals) of 0.013 g L sub(-1) and 0.079 g L sub(-1), respectively, thus suggesting that runoff from roads and near-shore construction could be contributing to reef decline. The AADAMS is an accurate, reliable system for highly replicated ecotoxicological studies of sensitive aquatic organisms, which are important indicators of ecosystem health.

Specifically, it has been suggested that each host tree species has a specific subset of the local species pool according to its own set of properties, e.g. physicochemical characteristics of the bark, tree architecture, or leaf phenology patterns. times METHODS: A novel, quantitative approach to this question is presented, taking advantage of a complete census of the vascular epiphyte community in 0.4 ha of undisturbed lowland forest in Panama. For three locally common host-tree species (Socratea exorrhiza, Marila laxiflora, Perebea xanthochyma) null models were created of the expected epiphyte assemblages assuming that epiphyte colonization reflected random distribution of epiphytes in the forest. times Key Results In all three tree species, abundances of the majority of epiphyte species (69-81 %) were indistinguishable from random, while the remaining species were about equally over- or under-represented compared with their occurrence in the entire forest plot. Permutations based on the number of colonized trees (reflecting observed spatial patchiness) yielded similar results. Finally, a third analysis (canonical correspondence analysis) also confirmed host-specific differences in epiphyte assemblages. In spite of pronounced preferences of some epiphytes for particular host trees, no epiphyte species was restricted to a single host. times CONCLUSIONS: The epiphytes on a given tree species are not simply a random sample of the local species pool, but there are no indications of host specificity either.

Freshwater inflow (FWI) rates in many estuaries are changing due to changing land use patterns, water diversions for human consumption, and climate effects, but there are no standard criteria to determine minimum inflow rates. An ecological indicator is required so models can be produced to predict how changing hydrology might affect estuarine metabolic rates, productivity, or impairment. One indicator of estuarine metabolic rates is net ecosystem metabolism (NEM). It is hypothesized that metabolic rates (as indicated by NEM) will depend on recently delivered FWI. To test this hypothesis, daily NEM was calculated from high frequency changes in dissolved oxygen measurements in a shallow water estuary, Lavaca Bay, Texas, USA and related to FWI and other environmental conditions. There was a significant relationship between NEM and cumulative ten-day FWI in upper Lavaca Bay, with more heterotrophic conditions occurring after high FWI events. No significant relationship existed between NEM and FWI in lower Lavaca Bay, where other environmental conditions, such as tidal forcing, may be more influential. An empirical model simulating NEM's response to FWI in upper Lavaca Bay was more accurate during moderate to high flows than during low base-flow conditions. Thus, quantity of FWI and distance from the inflow point source constrained the dependence of NEM on FWI. NEM can be quite variable over time and within a bay dominated by a river at one end and ocean exchange at the other end. The range of environmental gradients over time and within an estuary will determine how representative NEM at a single location is for an entire estuary. However, during high flow period pulses NEM can accurately predict shifts from balanced to heterotrophic conditions. Therefore, use of the NEM model as an indicator of FWI effects is constrained to regions in estuaries that are most effected by FWI because of proximity to the source or the size of FWI pulse events. The unique geologic, geographic, and climate signature's of individual estuaries will dictate the fit of this model in space and time. Inclusion of other environmental factors, such as temperature or irradiance, is necessary to improve the NEM model during low base-flow conditions. It is concluded that the NEM model does provide a useful indicator of FWI effects on ecosystem metabolic rates as it works well in the upper regions of Lavaca Bay and during freshwater inflow pulses where and when freshwater inflow has more influence than other environmental factors.

Robust statistical methods for determining the strength of edge effects are a vital requirement for the effective management of species that are negatively affected by habitat boundaries in heavily fragmented landscapes, but development of such methods has been slow. We define edge effects as being composed of two complementary, and statistically definable, components: magnitude (the degree of difference in response values between patch and matrix interiors) and extent (the distance over which the difference in response values can be detected). We present a statistical approach to rigorously delineate edge-effect magnitude and extent. Our approach adapts a form of the general logistic model to describe continuous response functions for any biotic or abiotic variable across ecological boundaries from the landscape matrix into focal patch habitats. The model describes sigmoid and unimodal response functions that have been both theoretically predicted and empirically demonstrated. We use the second derivatives of the functions as an objective means to calculate the magnitude and extent of edge effects, and present a bootstrap technique for calculating confidence intervals around these values. Synthesis and applications. Our results show clearly that edge-effect magnitude and extent are not necessarily correlated, and therefore provide quantitatively different, and complementary, information about the strength of edge effects. Both effect magnitude and extent can be easily used for cross-study comparisons, either by directly comparing the absolute values of response variables in the patch and matrix, or by converting those values to a percentage change. Furthermore, this method provides a management tool for more accurately predicting the presence, spatial location and utilization of core habitat by species in fragmented landscapes.

Several subspecies of ornate shrews are considered 'mammal species of special concern' in California by the Department of Fish and Game, and one (Sorex ornatus relictus) has recently been listed as endangered. Populations of shrews around Buena Vista Lake have been diminished or extirpated due to habitat deterioration and human development. In order to study the patterns of genetic variation in isolated populations of Buena Vista Lake shrews, we developed 10 polymorphic microsatellite loci. There were 6-27 alleles per locus, and the loci had heterozygosity values that ranged from 20 to 80%. In addition, we screened 20 different populations of S. ornatus, eight species within two subfamilies of shrews (Soricinae and Crocidurinae), as well as in a mole (Talpidae, Neurotrichus gibbsii), to determine if these loci could be informative in other species as well.

Three hundred and thirty-nine individuals were genotyped into one of 31 operational taxonomic units (OTUs) based on the nucleotide sequence of their mitochondrial ATPase 6 & 8 genes (842-839 bp). Contrary to inference based on the species-level taxonomy of these genera, molecular data identified only a single case of sympatry between closely related OTUs, despite extensive parapatry. Polytomies dominate the mtDNA-based phylogenies and demonstrate multiple, noncontemporaneous waves of rapid expansion across Mesoamerica from South American sources. Analyses based on genetic distances observed among congeneric species of Mesoamerican primary freshwater fishes in comparison to divergence between transisthmian marine fishes permit the strong inference that the Pliocene rise of the Panama land bridge provided the first opportunity for the colonization of Mesoamerica by Characiform fishes. We develop a priority-effect model, based on the assumption that genetically closely related OTUs share similar ecological niches, to reconcile the general lack of contemporary sympatry between closely related OTUs with the substantial historical connectivity among Mesoamerican drainages demonstrated by the rapid expansion of Brycon, Bryconamericus, and Cyphocharax. Finally, in most cases, we infer that the westerly limits of freshwater fish distributions in Mesoamerica are more consistent with being defined by ecological factors rather than by dispersal limitation.

Solution phosphorus-31 nuclear magnetic resonance ( super(31)P NMR) spectroscopy was used to assess the conventional colorimetric procedure for phosphorus speciation in alkaline extracts of organic soils from the Florida Everglades. Molybdate colorimetry markedly overestimated organic phosphorus by between 30 and 54% compared to NMR spectroscopy. This was due in large part to the association of inorganic phosphate with organic matter, although the error was exacerbated in some samples by the presence of pyrophosphate, an inorganic polyphosphate that is not detected by colorimetry. The results have importantimplicationsfor our understanding of phosphorus biogeochemistry in wetlands and suggest that alkaline extraction and solution super(31)P NMR spectroscopy is the only accurate method for quantifying organic phosphorus in wetland soils.

AN - 67977011; 16544123 AB - We show that uloborid spiders, which lack the poison glands typical of nearly all other spiders, employ thousands of wrapping movements with their hind legs and up to hundreds of meters of silk line to make a shroud that applies substantial compressive force to their prey. Shrouds sometimes break the prey's legs, buckle its compound eyes inward, or kill it outright. The compressive force apparently results from the summation of small tensions on sticky lines as they are applied to the prey package. Behavioral details indicate that wrapping is designed to compact prey; in turn, compaction probably functions to facilitate these spiders' unusual method of feeding. This is the first demonstration that prey wrapping by spiders compacts and physically damages their prey, rather than simply restraining them.

The ammonite fauna indicates a lower Albian age of the fauna (Cleoniceras besairiei Zone). The taxonomic position of the species described earlier is reviewed, incorporating new data on shell structure and protoconch morphology. Twelve species and one genus are new, with four species described in open nomenclature. The oldest hitherto known representatives of Cocculina sensu lato, Iphitus, Conjectura, Entomope, Tomura, and possibly Vatopsis and Paladmete, are described. Nacre is documented in a species of Semisolarium, providing further evidence for the position of this genus within the Vetigastropoda. Eight of the species occur also in the Cretaceous of Europe or are tentatively assigned to European species. Three species have close relatives in the Aptian/Albian of Japan, one species may have relations to the Albian of Texas. The new genus is Mahajangina (family uncertain) for a species having a small, trochispiral teleoconch with spines on the periphery, and a conical, bicarinate larval shell. The new species are: Cirsocerithium collignoni, Zardinistylus betsibokaensis, Pommerozygia mahajangensis, Conjectura minuta, Buvignieria berwaldi, Mahajangina weitschati, Entomope crassilabrum, Paladmete? rasoarinoroae, Tomura ambatolafiensis, Carinathilda parviruga, Carinathilda bandeli, and Gymnothilda pagodoidea.

For more than a hundred years researchers have wrestled with the questions of what domestication is, how it is detected, and why it happened. The past decade in particular has witnessed a remarkable acceleration of interest in domestication, thanks to advances in our ability to detect the context, timing, and process of domestication in a wide array of different plant and animal species around the world.1 This review focuses on overarching issues of defining, documenting, and explaining the domestication of plants and animals, tracing a path through often discordant viewpoints to offer some new perspectives.

One site, referred to as PH, has a layer of organic soil as deep as 2.5 m underlain by sandy alluvial deposits. Hydraulic conductivity (K) ranged between 2 times 10-5 and 7 times 10-3 cm per second. The second site, JP, is a marl fen in which calcium carbonate precipitates (K range 1 to 7 times 10-5 cm per second) confine the underlying sand aquifer. During the 2002 growing season, we installed two sets of data loggers, one at the wetland edge and another in the interior fen area; one logger recorded hourly water table (WT) elevation and the other recorded hydraulic head at a depth of 1 to 2 meters. A tipping bucket rain gauge and temperature data logger also were installed. Rain events damped diurnal WT fluctuations induced by evapotranspiration; the range of fluctuation varied directly with hydraulic conductivity of the shallow soil substrate. Discharge gradients intensified during dry periods. Despite the low K measures, water chemistry data indicated that the observed changes in ground-water flow significantly affected shallow pore water concentrations of reduced iron, sulfate, alkalinity and plant growth- limiting nutrients. These results indicate that weather-induced changes in groundwater discharge rates will influence biogeochemical processes within the fens, ultimately affecting fluxes of chemical constituents to down-gradient waterbodies and the species composition of the P-limited and species-rich fen plant communities. Wetland substrates with higher K likely will have a faster response to changes in the water budget and/or short-term weather patterns.

Most studies of SAV habitat requirements have focused on estuarine water quality parameters that modify light availability, but linkages to estuary and local watershed landscape characteristics are less well quantified. We analyzed the effects of watershed use and subestuary characteristics on SAV abundance for 101 shallow subestuaries of Chesapeake Bay and their local watersheds. The landscape analyses were applied to develop a number of subestuary metrics (such as subestuary area, mouth width, elongation ratio, fractal dimension, etc.) and watershed metrics (such as watershed area, ratio of local watershed area to subestuary volume, etc.). We calculated SAV coverage for each subestuary in each year during 1984-2003 as a proportion of potential SAV habitat (area mixed-agricultural > agricultural > developed. Change point analyses indicated strong threshold responses of SAV abundance to the proportion of developed land, point source nutrient inputs and the density of septic systems in the watershed.

In particular, erosion rates derived from the Universal Soil Loss Equation (USLE) and runoff estimates based on the Curve Number method (CN) provide the basis for predicting sediment loads to streams in more than a dozen integrated watershed models. However, there have been limited opportunities to validate this approach across multiple watersheds. We compared continuous stream monitoring data collected in 104 sub-basins of the Chesapeake Bay watershed with predictions from the USLE and five related sediment delivery models. Models were implemented using public domain datasets and ArcGIS. None of the model predictions correlated positively with observed sediment yields (it r range -0.21 to -0.02; it p range 0.07 to 0.89), and in fact, area-based sediment delivery models were negatively correlated with observed sediment loads (it r = -0.24 to -0.23; it p = 0.03 to 0.04). Multivariate statistical analyses indicated that soil erodibility, % impervious area, relief ratio, and stream discharge significantly influence sediment loads (it r2 = 51%, it p < 0 .001), but there remains a large proportion of unexplained variance. Results emphasize the need for the scientific community to continue investigating the linkages between stream water quality and watershed characteristics and to incorporate findings into empirical models that can be integrated easily with watershed models.

On one farm, we sampled shallow groundwater at the edge of croplands and within adjacent riparian buffers. Groundwater nitrate concentrations were lower inside the buffers than at the cropland edge. Patterns of isotope abundance were consistent with denitrification because both delta arrow right 5N and delta arrow right 8O increased as nitrate concentration decreased, reflecting the preferential denitrification of nitrate containing lighter isotopes. We also analyzed the delta arrow right 5N and delta arrow right 8O of nitrate in baseflow from 15 third- order streams. Baseflow nitrate concentrations increased with the proportion of agricultural land in the streams watershed (r2= 0.74). The residuals of the regression of nitrate concentration vs. percent agriculture were inversely correlated with the delta arrow right 8O of the nitrate. That is, watersheds with lower nitrate concentrations than would be expected from the proportion of agricultural land had higher delta arrow right 8O composition in the nitrate. This is consistent with the hypothesis that denitrification decreases nitrate concentrations to different extents in the different watersheds. The effect of denitrification on delta arrow right 5N in stream nitrate was less clear, possibly because delta arrow right 5N is also influenced by nitrate source, being higher in nitrate derived from manure than in nitrate derived from inorganic fertilizer. Our results suggest that the delta arrow right 8O of nitrate could be used to assess denitrification at the scale of entire watersheds.

AN - 19994985; 7425183 AB - Human modification of the landscape has increased riverine transport of nutrients, including phosphorus, and severely impacted the water resources of the Chesapeake Bay, one of the worlds largest estuaries. To better understand the potential of the Chesapeake Bay watershed to export phosphorus, we used a budget approach to estimate net anthropogenic phosphorus input (NAPI) for each county in the watershed. Phosphorus exchanges into and out of counties include fertilizer application and trade in food and feed. Phosphorus transfers among crops, livestock, and humans within each county were incorporated into the budget to assess the contribution of each sub-component to NAPI. Among counties, NAPI ranged from a low of -7 kg P ha-1 to a high of 162 kg P ha-1. Fertilizer application (R2 = 0.40), human population density (R2 = 0.79), and livestock production intensity (R2 = 0.27) all had significant positive linear relationships with county NAPI. The mean NAPI for Chesapeake Bay watershed significantly increased from about 2.6 kg P ha-1 in 1987 to about 3.3 kg P ha-1 in 2002. The trade of food and feed was as influential on NAPI as the crop uptake and livestock food production sub-components combined. We used the county phosphorus budgets to estimate the components of NAPI for 62 study watersheds where total phosphorus discharges were measured with automated stream sampling stations. Across all the study watersheds, NAPI was significantly correlated with in-stream phosphorus flux (R2 = 0.17), but grouping watersheds by physiographic province strengthened the relationships (R2 = 0.33 to 0.78).

Consumption of L. majuscula by fish did not differ between wild and captive-bred fish (P = 0.152) but did differ between bloom location (P = 0.039). No relationship was found between consumption rates and lyngbyatoxin-a concentration (r super(2) = 0.035, P = 0.814). No correlation existed between C : N and proportion of food consumed when all food types were analysed statistically, whereas a clear correlation was observed when L. majuscula was removed from the calculations. In simulated bloom conditions, fish avoided ingestion of L. majuscula by feeding through gaps in the L. majuscula coverage. Both wild and captive-bred S. fuscescens showed a distinct feeding pattern in 10 day no-choice feeding assays, with less L. majuscula being consumed than the preferred red alga Acanthophora spicifera. Lyngbya majuscula however, was consumed in equal quantities to A. spicifera by wild S. fuscescens when lyngbyatoxin-a was not detectable. Wild fish probably do not preferentially feed on L. majuscula when secondary metabolites are present and are not severely impacted by large L. majuscula blooms in Moreton Bay. Furthermore, poor feeding performance in both captive-bred and wild S. fuscescens suggests that they would exert little pressure as a top-down control agent of toxic L. majuscula blooms within Moreton Bay.

Females sequentially visit several courting males before they stay with one and mate in his burrow, and they preferentially approach burrows with hoods. While moving between burrows, crabs are at risk of predation by birds and they sometimes run to objects that provide temporary cover. Thus, the female preference for burrows with hoods may help females to avoid predators. Could selection for predator avoidance produce a directional preference for especially large hoods? To examine this possibility, we made multiple replicas of two kinds of hood models with exaggerated dimensions (super models and wall models) and a single model with average dimensions (average models). Super models were four standard deviations taller and two standard deviations wider than average-size natural hoods. Wall models were of average height but near the maximum width of natural hoods; when males 'overbuild', they construct wall-like hoods. We replaced males' hoods with these models and measured their effects on male attractiveness. Males with exaggerated models neither encountered nor attracted more females than did males with average models or natural hoods. Females did not show a directional preference for larger hoods. The attractiveness of hoods may plateau with increasing size because discrimination between average and larger hoods may result in fatal hesitation, preventing the evolution of a directional preference for an exaggerated form of this courtship signal. Males build hoods from pure sand, so males may build unusually large hoods because they are more durable, not because they are better signals.

We combine spatial information on various biophysical, demographic and infrastructural factors in the Brazilian Amazon with satellite data on deforestation to evaluate the relative importance of each factor to deforestation in the region. We assess the sensitivity of results to alternative sampling methodologies, and compare our results to those of previous empirical studies of Amazonian deforestation. Our findings, in concert with those of previous studies, send a clear message to planners: both paved and unpaved roads are key drivers of the deforestation process. Proximity to previous clearings, high population densities, low annual rainfall, and long dry seasons also increase the likelihood that a site will be deforested; however, roads are consistently important and are the factors most amenable to policymaking. We argue that there is ample evidence to justify a fundamental change in current Amazonian development priorities if additional large-scale losses of forests and environmental services are to be avoided.

Collection of nest material beneath termitaria and infrared video filming indicated that males of L. silvicolum excavate and maintain cavities inside active termite nests. A binary logistic regression analysis showed that to be suitable as roosts, termite nests have to be larger than 30 cm in diameter and taller than 30 cm, well shaded, with few transecting branches, and freely accessible from below. Use of active termite nests as roosts may provide several benefits to L. silvicolum, including reduction of competition for roost sites with sympatric bat species, reduced parasite load and a suitable microclimate. A comparison of number of all termite nests in selected forest plots with number of termite nests that are potentially suited as bat roosts and number of termite nests that are actually used by bats suggests that L. silvicolum may not be roost-limited on BCI in spite of its highly specialized roost choice.Original Abstract: Se estudio la estructura, modificacion y disponibilidad de la percha para Lophostoma silvicolum (Phyllostomidae), un murcielago insectivoro en la Isla Barro Colorado (BCI), Panama. La coleccion de material de las perchas debajo de los termitarios y la filmacion con videocamara infrarroja, indica que los machos de L. silvicolum excavan y mantienen cavidades en el interior de los nidos activos de la termita. Un analisis con regresion logistica binaria demostro que para ser adecuados como perchas, los nidos de la termita deben ser mas de 30 cm en diametro y 30 cm de altura, con buena sombra y pocas ramificaciones que se crucen, asi como ser facilmente accesibles desde abajo. El uso de nidos activos de la termita como percha puede proporcionar algunos beneficios a L. silvicolum, incluyendo la reduccion de la competencia para perchas con especies de murcielagos simpatricas, la reduccion en la carga de parasitos y un microclima adecuado. Una comparacion del numero total de los nidos de la termita en porciones selectas de bosque, con el numero de nidos que potencialmente pueden utilizarse como perchas y el numero de ellos que en realidad estan siendo usados, sugiere que las poblaciones de L. silvicolum pueden no estar limitadas a las perchas en BCI, a pesar de su altamente especializada preferencia por las perchas.

Humans cause deforestation, and humans living in rural settings have the greatest impact on extant forest area in the tropics. Current human demographic trends, including slowing population growth and intense urbanization, give reason to hope that deforestation will slow, natural forest regeneration through secondary succession will accelerate, and the widely anticipated mass extinction of tropical forest species will be avoided. Here, we show that the proportion of potential forest cover remaining is closely correlated with human population density among countries, in both the tropics and the temperate zone. We use United Nations population projections and continent-specific relationships between both total and rural population density and forest remaining today to project future tropical forest cover. Our projections suggest that deforestation rates will decrease as population growth slows, and that a much larger area will continue to be forested than previous studies suggest. Tropical forests retracted to smaller areas during repeated Pleistocene glacial events in Africa and more recently in selected areas that supported large prehistoric human populations. Despite many caveats, these projections and observations provide hope that many tropical forest species will be able to survive the current wave of deforestation and human population growth. A strategy to preserve tropical biodiversity might include policies to improve conditions in tropical urban settings to hasten urbanization and preemptive conservation efforts in countries with large areas of extant forest and large projected rates of future human population growth. We hope that this first attempt inspires others to produce better models of future tropical forest cover and associated policy recommendations.Original Abstract: La deforestacion y la perdida de habitat pueden precipitar una crisis de la extincion de especies del bosque tropical. El mayor impacto sobre los bosques tropicales existentes es la deforestacion y otras actividades por humanos que viven en las areas rurales Las tendencias demograficas humanas actuales sugieren que una reduccion en el crecimiento de la poblacion y un aumento en la urbanizacion podran causar una reduccion en la deforestacion, una aceleracion de la sucesion secundaria, y evitar la esperada extincion en masa de especies del bosque tropical. Aqui, demostramos que la proporcion del potencial de la cobertura del bosque restante esta correlacionada con la densidad demografica humana entre paises; esto es aplicable a las zonas tropicales y templadas. Usamos proyecciones de las Naciones Unidas sobre crecimiento poblacionales y las relaciones entre la densidad poblacional rural y el bosque existente para proyectar la cobertura del bosque tropical en el futuro. Nuestras proyecciones sugieren que las tasas de deforestacion disminuiran conjuntamente con una reduccion en el crecimiento poblacional, y a la vez, areas mas extensas que los sugeridos en otros estudios permaneceran con cobertura forestal. Los bosques tropicales se retraeron a areas mas pequenas durante los repetidos eventos glaciales del Pleistoceno en el Africa y mas recientemente en areas selectas ocupadas por grandes poblaciones humanas prehistoricas. A pesar de muchas advertencias, estas proyecciones y observaciones dan la esperanza de que muchas especies del bosque tropical podran sobrevivir la presente tasa de deforestacion y crecimiento poblacional humano. Una estrategia para preservar la biodiversidad tropical puede incluir politicas para mejorar las condiciones ambientales en areas urbanas tropicales. Esto con el objectivo de acelerar la urbanizacion y programas de conservacion preventivos en paises con areas extensas de bosque con un alto indice de crecimiento poblacional projectado para el futuro. Esperamos que nuestro primer esfuerzo inspire a otros investigadores a producir mejores modelos para predecir la cobertura del bosque tropical y politicas asociadas con la conservacion de estos.

Observations in natural settings and laboratory experiments have shown that changes, such as increased grain rounding and decreased size due to particle breakage, wear, and attrition, tend to be progressive along the dispersal path. In marked contrast, this study records highly variable and poorly developed particle-texture trends downslope along short (<5 km) channels that extend directly from a high-relief carbonate source area down to the shore of Lake Annecy in the western Alps, SE France. The observed inconsistent patterns are measured in both a region-wide analysis using all collected samples and also in a more specific survey of samples in six different channels incised on the steep, topographically irregular mountain flanks that border the lake. The major factor responsible for the irregular downslope patterns of roundness, sphericity, and size in the Annecy study area is the lateral introduction of sediment into the fluvial channels along dispersal paths. Episodic failure of mechanically unstable sediments and their transport down steep valley walls bring less-abraded sediment of variable shape and size along the dispersal paths. The valley wall sediment influx factor warrants further examination to better interpret sedimentation processes in dissected, high-gradient terrains that border coastal areas.

This widespread evolutionary pattern could result from sustained sexually antagonistic coevolution, or from other types of selection such as female choice or selection for species isolation. I reviewed the extensive but under-utilized taxonomic literature on a selected subset of insects, in which male-female conflict has apparently resulted in antagonistic coevolution in males and females. I checked the sexual morphology of groups comprising 500-1000 species in six orders for three evolutionary trends predicted by the sexually antagonistic coevolution hypothesis: males with species-specific differences and elaborate morphology in structures that grasp or perforate females in sexual contexts; corresponding female structures with apparently coevolved species-specific morphology; and potentially defensive designs of female morphology. The expectation was that the predictions were especially likely to be fulfilled in these groups. A largely qualitative overview revealed several surprising patterns: sexually antagonistic coevolution is associated with frequent, relatively weak species-specific differences in males, but male designs are usually relatively simple and conservative (in contrast to the diverse and elaborate designs common in male structures specialized to contact and hold females in other species, and also in weapons such as horns and pincers used in intra-specific battles); coevolutionary divergence of females is not common; and defensive female divergence is very uncommon. No cases were found of female defensive devices that can be facultatively deployed. Coevolutionary morphological races may have occurred between males and females of some bugs with traumatic insemination, but apparently as a result of female attempts to control fertilization, rather than to reduce the physical damage and infections resulting from insertion of the male's hypodermic genitalia. In sum, the sexually antagonistic coevolution that probably occurs in these groups has generally not resulted in rapid, sustained evolutionary divergence in male and female external sexual morphology. Several limitations of this study, and directions for further analyses are discussed.

Our research objectives were to quantify variability in seed production and rate of maturation among individual Pinus taeda L. (Pinaceae) trees growing in elevated CO sub(2) (ambient plus 200 mu L L super(-1)) since 1996. Estimating tree fecundity in nature is frustrated by the difficulty of counting seeds from individual trees and the need for long-term data. We have used a hierarchical Bayes approach to model individual tree fecundity, accounting for the complexity of experimentation in a natural setting over multiple years. The study presented here demonstrates large variability in natural fecundity rates and contributes to our understanding of how both interannual variation and population heterogeneity influence elevated CO sub(2) effects. We found that trees growing under elevated CO sub(2) matured earlier and produced more seeds and cones per unit basal area than ambient grown trees. By 2004, trees grown in high CO sub(2) had produced an average 300 more seeds per tree than ambient grown trees. Although there was a trend toward decreasing mean CO sub(2) effect (difference in fecundity between elevated and ambient treatments) over time, the hierarchical analysis indicates that this decrease comes from the emergence of a few highly fecund ambient grown trees by 2002, rather than acclimation or downregulation among the fumigated trees. The most important effect of increased CO sub(2) in forest ecosystems may be the increase in fecundity reported here. Although biomass responses can sometimes be large, the increase in fecundity can have long-term impacts on forest dynamics that transcend the current generation.

The radial slope of fans where debris flow processes dominated is constant while fluvially-fed fans have a concave-upward shape. We find the power law regression of upstream slope- distance profiles is the preferred approach for assessing concavity. Concavity index, the exponential determined via power law regression analysis, is an accurate reflection of the magnitude of the concavity and thus a qualitative measure of the relative influence of fluvial processes on the fan. Fan length and surface gradient are inversely correlated: debris flow fans are shorter and steeper (>15 degree ) than their fluvial counterparts. The results of this investigation provide criteria to evaluate hypothesized formation processes and provide constraints on the amount of fluid and timescales involved in the generation of comparably-sized fans within Mojave Crater, Mars.

In a 4-year study of 188 swift foxes, we used microsatellite analysis at 11 loci along with spatial observations to investigate swift fox mating strategies. The mating strategies used by swift foxes were highly diverse. Previous field observations have indicated that the swift fox is socially monogamous. However, we found that extrapair mating was a common breeding strategy; 52% of offspring were sired by a male that was not the mate of their mother. There was also variation in the structure of social groups. Of 59 social groups, the most common consisted of a male and female pair (93% of social groups); however, four stable trios of both one female and two males (5%) and two females and one male (2%) were also evident. The trio groups were spatially associated, and at least one member of each trio was highly related to a member in at least one other trio. Swift foxes also engaged in mate switching, which refutes the prevailing hypothesis that they always mate for life. Thus, we found that the mating system of the swift fox is highly diverse and substantially more complex than previously believed. We discuss factors that may influence which strategies are adopted and whether they are adaptive.

Due to the uncertainty concerning the appropriate currency of resource allocation to reproduction, the temporal changes of the contents of total non-structural carbohydrates (TNC) and of all major nutrient elements in different plant parts were studied (stems, green leaves, non-green leaf bases, roots and reproductive structures when present). times Key Results Although TNC varied with time in all compartments, this variation was more related to seasonal fluctuations than to reproductive status. The contents of the nutrient elements, N, P, K, Mg and S, on the other hand, showed significant differences between reproductive and non-reproductive individuals, while Ca did not change with reproductive status. Differences in nutrient contents were most pronounced in stems. Seeds were particularly enriched in P, much less so in N and the other nutrient elements. Model calculations of nutrient fluxes indicate that a plant needs about 2 years to accumulate the amount of P invested in a fruit crop, while the estimated uptake rates for N were much faster. times CONCLUSIONS: Since most mature individuals of this species fruit every other year, it is hypothesized that P is the prime limiting factor for reproduction. These findings therefore add to an increasing body of evidence that P rather than N is limiting growth and reproduction in vascular epiphytes.

2006-026653 AB - The Rocky Mountain orogenic plateau has the highest mean elevation and topographic relief in the contiguous United States. The mean altitude exceeds 2 km above sea level and relief increases from 30 m in the river valleys of the Great Plains to more than 1.6 km deep in the canyons and basins of the Rocky Mountains and Colorado Plateau. Despite over a century of study, the timing and causes of elevation gain and incision in the region are unclear. Post-Laramide development of relief is thought to either result from tectonic activity or climatic change. Interpretation of which of these causes dominated is based upon reconstruction of datums developed from, and supported by, paleoelevation proxies and interpretations of landscape incision. Here we reconstruct a datum surface against which regional incision can be measured in order to evaluate late Cenozoic tectonic and climatic influences. The distribution, magnitude, and timing of post-Laramide basin filling and subsequent erosion are constrained by depositional remnants, topographic markers, and other indicators across the region. We suggest that post-Laramide basin filling resulted from slow subsidence during Oligocene to Miocene time. Incision into this basin fill surface began in late Miocene time and continues today. The pattern of incision is consistent with control by localized extensional tectonism superimposed upon regional domal surface uplift. Localized extension is associated with the projection of the Rio Grande Rift into the central Rockies, and the domal uplift generally coincides with the position of buoyant mantle anomalies interpreted at depth. If the magnitudes of incision directly reflect magnitudes of surface elevation gain, they are less than can be resolved by existing paleoelevation proxy methods. In addition, the combination of post-Laramide subsidence followed by regional surface uplift reduces the net magnitude of surface elevation change since Laramide time.

Material from a recent three-year collection interval was compared to an earlier three-year collection subsample to determine signal consistency over time. The bulk of the assemblage is comprised of cercopithecoid monkey remains, reflecting the taxonomic composition of the Ngogo area. Taxonomic composition of the assemblage remains highly consistent over the collection period. Bone survivability and fragmentation profiles, as well as damage patterns, also were investigated. Crowned hawk-eagles inflict much less damage to prey skeletons than do mammalian carnivores. Crania, scapulae, and hindlimb elements are most likely to survive predation by crowned hawk-eagles and to be concentrated at nest sites, but these elements (especially crania) show age-specific patterns of fragmentation and damage. Bone survivability profiles remain highly consistent throughout the duration of the collection period. Fragmentation and damage patterns--when tallied quantitatively--are more variable, but do not resemble those expected under predation by mammalian carnivores. Regurgitated elements in hair boluses also were examined; when compared with the rest of the assemblage, they show very different patterns. In summary, crowned hawk-eagle predation provides a taphonomic signature distinguishable from those of other predatory accumulating agents (e.g., non-human mammalian carnivores, owls, and humans), and this signal remains consistent over time, leading to the expectation that it may remain intact in fossil assemblages.

The basic birnessite-type structure consists of sheets of Mn octahedra separated by approximately 7 or approximately 10 Aa ("buserite") interlayer regions filled with cations and water. Synthetic birnessite-like structures were produced through cation exchange reactions with synthetic Na-birnessite. The unheated, synthetic Mg (super 2+) , Ca (super 2+) , and Ni (super 2+) layer structures have an approximately 10 Aa interlayer spacing, whereas the other cation-exchanged synthetic birnessites and the related mineral chalcophanite have an interlayer spacing of approximately 7 Aa. The Li (super +) , Na (super +) , K (super +) , Cs (super +) , and Pb (super 2+) synthetic birnessites each contain two to three structurally different water sites, as evidenced by multiple H (sub 2) O bending and stretching modes in the infrared spectra. The complexity of the water bands in these spectra is likely related to disordering of cations on the interlayer sites. H-birnessite contains structural water and either hydroxyl, hydronium (H (sub 3) O (super +) ), or both. The small difference in the width of the water stretching modes between room temperature and -180 degrees C indicates that the water molecules in birnessite-like structures are predominantly structurally, rather than dynamically, disordered. Most of the synthetic birnessites, including Na- and K-birnessite, undergo significant water loss at temperatures below 100 degrees C. There is a linear relationship between the temperature at which most of the water is lost from a given cation-exchanged birnessite and the heat of hydration of the interlayer cation. This finding implies that the interlayer water is strongly bound to the interlayer cations, and plays an important role in the thermal stability of birnessite-like structures.

Unlike other isorophid edrioasteroids, Thresherodiscus has branching ambulacra, an unusual hydro-gonopore, differentiated interambulacral plates bearing respiratory structures, and ambulacra that extend onto the peripheral rim. Except for the turreted thecal shape, Lispidecodus is a rather typical discocystinid edrioasteroid. Phylogenetic analysis weakly supports the placement of Thresherodiscus within Agelacrinitidae and strongly places Lispidecodus within Discocystinae.

The FeO-rich clast in Pesyanoe is dominated by olivine and pyroxene phenocrysts with mineral compositions slightly less FeO-rich than is typical for H chondrites. In Allan Hills (ALH) 84008, the oxide-bearing clast consists of a single forsterite grain rimmed by an array of sulfides, oxides, and phosphides. We consider a number of possible origins. We can exclude formation by melting of oxide-bearing chondrules and CAIs formed in enstatite chondrites. The Pesyanoe clast may have formed in a more oxidized region of the aubrite parent body or, more likely, is a foreign clast from a more oxidized parent body. The ALH 84008 clast likely formed by reaction between sulfides and silicates as a result of cooling, oxidation, or de-sulfidization. This clast appears to be the first oxide-bearing clast from an aubritic breccia that formed on the aubrite parent body. Identification of additional oxide-bearing clasts in aubrites could shed light on whether this was a widespread phenomenon and the origin of these enigmatic objects.

Volatile elements in particular play an important role in the generation of aqueous fluids and the transport of fluid mobile elements. Here we report volatile contents of quenched glasses from pillow-lava rims in the Kermadec Arc-Havre Trough subduction system to provide constraints on the source, generation, and composition of slab-derived aqueous fluids. Water ( approximately 1.5 wt.% in glasses, 2.5 wt.% in two melt inclusions), carbon (up to 16 ppm in glasses, 180 ppm in one inclusion) and sulphur (80% Ba and Pb, and >98% of Cl is required to be derived from aqueous slab-derived fluids. We propose a single homogenous reservoir for the aqueous fluid source. This reservoir is most likely to be hydrated serpentinite formed above the subducting slab by fluids derived from altered oceanic crust and subducting sediment. Dehydration of the serpentinite occurs as it descends into the mantle, transporting fluid mobile elements into the overlying mantle and triggering partial melting. The similarity of aqueous fluid compositions derived for other oceanic arcs suggests that this process may occur in arc systems worldwide.

We describe a general relativistic force-free (GRFFE) formulation that allows general relativistic magnetohydrodynamic (GRMHD) codes to directly evolve the GRFFE equations of motion. Established, accurate and well-tested conservative GRMHD codes can simply add a new inversion piece of code to their existing code, while continuing to use all the already-developed facilities present in their GRMHD code. We show how to enforce the E.B= 0 constraint and energy conservation, and we introduce a simplified general model of the dissipation of the electric field to enforce the B super(2)-E super(2) > 0 constraint. We also introduce a simplified yet general method to resolve current sheets, without much reconnection, over many dynamical times. This formulation is incorporated into an existing GRMHD code (harm), which is demonstrated to give accurate and robust GRFFE results for Minkowski and black hole space-times.

However, a reliable tool for determining whether the procedure took place is lacking. We investigated chromophoric dissolved organic matter (CDOM) fluorescence as a tracer of mid-ocean exchange on nine research cruises out of Asia, Europe, and the USA, focusing on challenging source conditions (high salinity, low CDOM). Using parallel factor analysis, we identified nine independent fluorescent components present in varying concentrations in the ocean and in ballast water. One component was sufficient for predicting the coastal vs oceanic source of most ballast water samples. Across nine cruises, thresholds (1.7 and 0.7 ppb quinine sulfate equivalent units) at two fixed wavelength pairs ( lambda sub(ex)/ lambda sub(em) = 320/414 and 370/496 nm, respectively) discriminated coastal from oceanic ballast water in >95% of samples (N = 514). Our results suggest that single-and dual-channel fluorometers could be optimized for verifying ballast water exchange.

Ongoing studies will provide not only a better understanding of the ecology of marine turtles in particular and marine ecology in general, but also basic information essential for formulating and evaluating more effective conservation objectives and actions. Recent research indicates that these marine reptiles can play critical ecological roles such as critical marine plant grazers and sponge predators, as well as nutrient and energy transporters between different trophic levels, between terrestrial and marine environments, and between different parts of the oceans. Hence, marine turtles may serve as "keystone species," with roles that are decisive to the structure and function of certain ecological networks, or ecosystems. Yet, a clear understanding of the ecological roles of different life stages, populations, and species requires much more detailed study over much longer periods; to deal adequately with the slow maturation, long life spans, and dramatic fluctuations from year to year in both turtle population parameters and their environments, it is essential to conduct long-term studies and monitoring on issues related to ecological roles. Independent of the myriad ways that marine turtles interact with their environments and other species, it is clear that these reptiles play critical roles in diverse relationships with peoples of different societies: they are classical "flagship species." Their flagship role is based on the cultural and social values attributed to the animals by members of the societies with which they interact, and archaeological evidence shows that humans have attributed special importance to marine turtles for millennia. In addition to the great antiquity of human-turtle interactions, there is tremendous diversity, with cultural manifestations occurring around the world in multiple forms. During contemporary times marine turtles have been widely and actively used, either explicitly or implicitly, as icons to promote biological conservation, for numerous programs which show clear indicators of success. On the other hand, marine turtles also serve as flagships for other social initiatives, such as cultural identity and preservation, marketing, and other activities that appear contradictory to the objectives of conservation. It is not uncommon to find different sectors of the same society responding in very different ways to the same marine turtle flagship, and these sorts of confusion and conflict undermine both conservation and socio-cultural initiatives. Hence, it is essential to understand the complexities of human ecology when designing and evaluating initiatives that employ marine turtles as flagships. Conservationists must be especially careful of this problem. While the keystone role, or ecological function, of a species is essential for understanding the organism's natural history and relationship with its environment, the flagship role is a much more powerful tool for affecting conservation and understanding how people perceive and interact with the animals. Species with apparently little ecological significance can be of immense importance as flagships, and have been used to successfully promote major conservation initiatives with far-reaching effects. Without understanding the human-turtle relationship, no turtle conservation program can be effective - no matter how much "good science" it relies on.

We studied bird species composition, abundance, guild composition, and site tenacity of a 102 ha plot located in a cloud forest region of the Sierra Yalijux in Guatemala, half of which was primary forest and half young secondary forest (<7-years-old). Of the 100 species present 14 were restricted to the Endemic Bird Area 'Northern Central American highlands' (i.e. 66% of a total of 21 endemics). Five of the 100 analysed species, including one of the restricted-range species (Troglodytes rufociliatus), had a significantly different abundance in primary and secondary forests. Theoretical analysis suggests that seven species out of a community comprised of 141 bird species are already extirpated and only three out of the 14 present restricted-range species might survive the current state of deforestation. Insectivores were the dominant guild on the plot in terms of numbers of species, followed by omnivores, frugivores and granivores. However, in terms of individuals, omnivores made up nearly half of the bird individuals in primary forest, but declined by 44% in secondary forest, whereas granivores more than doubled in this habitat type. Numbers of species per guild were not significantly different between habitats, while numbers of individuals per guild were significantly different. In general, individuals per species are significantly different in the two habitats. Results suggest that most of the species that are currently surviving in the remnant forests of the Sierra Yalijux might be fairly well adapted to a range of forest conditions, but that populations of a number of restricted-range species might be small. Even generalists species like the Common Bush Tanager (Chlorospingus ophthalmicus) are less abundant in secondary vegetation than in primary forest of the study plot.

AN - 19442514; 6800329 AB - The characteristics of plant-mycorrhizae associations are known to vary in both time and space, but the ecological consequences of variation in the dynamics of plant-fungus interactions are poorly understood. For example, do plants associate with single fungi or multiple fungi simultaneously, and do the associations persist through a plant's lifetime or do plants support a succession of different fungi? We investigated these and other questions related to plant-fungus interactions in Goodyera pubescens, an evergreen terrestrial orchid of the eastern United States, that interacts with closely related fungi in the genus Tulasnella. Unlike the mycorrhizal associations of other plants, orchid-mycorrhizal associations only benefit the orchid, based on current evidence. Many terrestrial orchids have been found to associate with specific groups of fungi. This characteristic could potentially limit orchids to relatively narrow ranges of environmental conditions and may be a contributing factor in the decline of many orchids in the face of changing environmental conditions. We found that G. pubescens protocorms (developing embryos prior to leaf production) and adults associated with only one fungal individual at a time. The orchid-fungus association persists for years, but during a drought period that was associated with the death of many plants, surviving plants were able to switch to new fungal individuals. These results suggest that G. pubescens interacts with the same fungal partner during periods of modest environmental variation but is able to switch to a different fungal partner. We hypothesize that the ability to switch fungi allows G. pubescens to survive more extreme environmental perturbations. However, laboratory experiments suggest that switching fungi has potential costs, as it increases the risk of mortality, especially for smaller individuals. Our findings indicate that it is unlikely that switching fungi is a common way to improve tolerance of less severe environmental fluctuations and disturbances. These findings may have important implications for plant responses to severe climatic events or to more gradual environmental changes such as global warming.

This study was conducted to assess: (1) semen characteristics of wild-born cheetahs; and (2) the impact of three types of glycerol influence (duration of exposure, temperature, and method of addition) on sperm cryosensitivity. To evaluate the impact of duration of glycerol exposure, spermatozoa were incubated in Test Yolk Buffer (TYB) with 4% glycerol at ambient temperature (~22 super(o)C) for 15 vs. 60min before cryopreservation. To evaluate the influence of temperature and method of glycerol addition, spermatozoa were resuspended at ambient temperature either in TYB with 0% glycerol followed by addition of 8% glycerol (1:1 v/v; at ambient temperature vs. 5 super(o)C) or directly in TYB with 4% glycerol. All samples were cryopreserved in straws over liquid nitrogen vapor and evaluated for sperm motility and acrosomal integrity after thawing. Semen samples (n=23; n=13 males) contained a high proportion (78%) of pleiomorphic spermatozoa. Ejaculates also contained a high proportion of acrosome-intact (86%) and motile spermatozoa (78%). Immediately after thawing, a significant proportion of spermatozoa retained intact acrosomes (range, 48-67%) and motility (range, 40-49%). After thawing, incubation in glycerol for 60min at ambient temperature before freezing decreased (p0.05) impact on sperm cryosurvival. In summary, (1) wild-born cheetahs produce high proportions of pleiomorphic spermatozoa but with a high proportion of intact acrosomes; and (2) resuspension in 4% glycerol, followed by exposure for up to 60min at ambient temperature, had minimal effect on sperm motility and acrosomal integrity after cryopreservation. Results indicate the feasibility of cryopreserving cheetah spermatozoa under field conditions, providing a user-friendly method to capture and store gametes to enhance genetic management.

The size advantage hypothesis predicts that the optimal size at which an individual should change sex is a function of its size and the size and sex of its potential mates. I collected data on the size, sex, and grouping of individuals of 27 populations of 19 species of the calyptraeids, a family of protandrous marine gastropods that includes Crepidula. These data are used to test the following predictions about variation in size at sex change: (1) sex ratio is biased toward the first sex; (2) the ratio of the size at sex change to the maximum size is a life-history invariant; and (3) species that form variable-sized groups or stacks have more variation in size at sex change than species that show less variation in stack formation. Across all 19 species, sex ratio was not significantly more often biased toward the first sex than it was toward the second sex, although sex ratios were significantly male biased more often than they were significantly female biased. Sex ratios ranged from 0.05 to 0.91, and this variation was related to mode of development, skew in size distribution, and frequency of stacking, but not with maximum body size. There was little evidence that the ratio of size at sex change and maximum size is invariant. There is evidence that one of the main underlying assumptions of this life-history invariant, that male fertility increases with the same function of size in all species, is invalid for calyptraeids and probably for other animals. Finally, species that form larger stacks or mating groups had more variation in size at sex change within a population than species that were generally solitary. These results suggest that information about individual groupings should be included in predictions of life-history theory and that more information about the relationship between male fitness and size is also needed.

The new species is assigned to Loxioides on the basis of characters defined in a previous study of drepanidine phylogeny. The maxilla of the new species resembles that of L. bailleui (the only other member of the genus) in its distinctly foreshortened shape, but differs in size and several qualitative characters. The species was sympatric with Loxioides cf. bailleui during the Holocene on Kaua'i. Like L. bailleui, it may have been a resource specialist feeding mainly on leguminous pods. The radio-carbon chronology of the Makauwahi site indicates that the species became extinct in the late Holocene and, more tentatively, that it may have survived well beyond the time when humans first discovered and colonized Kaua'i.Una Nueva Especie de Pinzon de Hawaii (Drepanidini: Loxioides) de la Cueva Makauwahi, Kaua'iOriginal Abstract: Se describe una nueva especie de pinzon de Hawai a partir de dos fosiles de maxilas extraidos de sedimentos lacustres del Holoceno en la cueva Makauwahi, en la isla de Kaua'i. La nueva especie es asignada a Loxioides con base en caracteres definidos en un estudio previo sobre la filogenia de los Drepanidini. La maxila de la nueva especie es similar a la de L. bailleui (el unico otro miembro del genero) en su forma marcadamente achatada, pero difiere en tamano y en varios caracteres cualitativos. La especie fue simpatrica con Loxioides cf. bailleui durante el Holoceno en Kaua'i. Como L. bailleui, puede haber sido un especialista que se alimentaba principalmente de vainas de leguminosas. La cronologia de radiocarbono del sitio Makauwahi indica que la especie se extinguio durante el Holoceno tardio y de modo mas tentativo, que podria haber sobrevivido mas alla del tiempo en que los humanos descubrieron y colonizaron por primera vez Kaua'i.

AN - 17216418; 6777963 AB - The reproductive success of a male bird is often correlated with measurable traits that predict his intrinsic quality. Females are thought to base their selection of mates on the latter's 'quality' in order to gain their 'good genes'. Male Australian Magpies Gymnorhina tibicen of the white-backed race tyrannica were trapped in two breeding seasons. Measurements were taken of morphometric and other characteristics in order to discover whether particular traits of males were associated with: (1) percentage of offspring sired in the territory, (2) number of fledglings produced in the territory per season and (3) whether females select males for their 'good genes'. There were no consistently significant correlations between any of the measured variables and male Magpie reproductive success within territories. In particular, none of the traits measured had any consistent correlation with the percentage of offspring sired in a territorial group. This was an unexpected result given that the species is strongly territorial but also engages regularly in extra-group copulations. These findings appear contrary to the predictions of the 'good genes' hypothesis. The general lack of correlation between the variables and level of genetic paternity may in fact be due to females engaging in extra-group mating primarily to avoid breeding with a close relative rather than to choose a high-quality male. In this case, males would not have to be 'high quality', but merely genetically different from the female's social mate.
