TY - JOUR T1 - A survey of hydrous species and concentrations in igneous feldspars AN - 51831767; 2004-053351 AB - The hydrous components in 85 feldspars from various igneous environments spanning the range of naturally occurring compositions were examined with infrared spectroscopy. The feldspars contain structural OH (0-512 ppm H (sub 2) O), H (sub 2) O (0-1350 ppm H (sub 2) O), and NH (super +) (sub 4) (0-1500 ppm NH (super +) (sub 4) ) groups as well as fluid inclusions and alteration products. Although composition and structure do influence the type of hydrous species that can be incorporated into a particular feldspar mineral, the concentration of these species is not controlled by major-element composition. Coarse perthitic microclines have a heterogeneous distribution of hydrous species, and contain H (sub 2) O or NH (super +) (sub 4) in K-rich lamellae and fluid inclusions in Na-rich areas. The structural OH in plagioclase feldspars is not associated with twin boundaries or exsolution lamellae. All of the possible structural hydrous species are found in pegmatite feldspars, whereas volcanic feldspars contain only structural OH. The variation in OH concentration within a given feldspar composition suggests that fluids in the geologic environment play a role in determining the hydrogen concentration of each sample. The vast majority of plutonic feldspars have undergone partial or total equilibration with meteoric fluids during low-temperature (400-150 degrees C) hydrothermal exchange, obliterating any structural hydrogen and creating substantial concentrations of fluid inclusions (up to 4000 ppm H (sub 2) O) in the exchanged regions. The amount of water stored as fluid inclusions within feldspars in the upper crust (1X10 (super 19) kg) is small compared to the 1.35X10 (super 21) kg of water in the oceans, but is roughly equivalent to the reservoir of water stored in hydrous minerals in the upper crust.

While this may seem surprising in view of President Jefferson's interest in agriculture and mineral resources, conventional interpretation has generally held that the expedition was so overwhelmed by the new discoveries and observations of plants and animals that geologic information was given less attention. Perhaps a more accurate view is that geologic observations are more subtle within the accounts. While subsequent analyses have been more focused on botany and zoology, it is also true that geological observations of great interest were recorded early in the expedition. Fortuitously, the geology of the route along the Missouri River afforded an astonishingly good introduction to a general section of Upper Cretaceous and Early Tertiary strata in sequence lower to upper, a fact now recognized, but obscured from the expedition itself. Fossil discoveries are so common there now that it is difficult to understand why the expedition did not record more of them. The Soldier River discovery of a fish fossil, Saurocephalus lanciformis, presumably moved from original context, has long defied complete interpretation, but the specimen still exists and is subject to further analysis. The more perplexing journal entries regarding a so-called petrified fish (September 10, 1804) almost certainly refer to a Cretaceous reptile, likely Tylosaurus sp., noting recent discoveries in the area. Unfortunately, no specimen has been found that would document the discovery. As a footnote to history, the expedition's naming of Corvus Creek, based on the observation of magpies there, ultimately bestowed the name Crow Creek on the Siouxan peoples whose reservation is one of the most scientifically productive two hundred years later.

The process of determining the availability or even the existence of Earth history data remains a time-consuming and error-prone enterprise because there are no centralized depositories or Web-enabled means for locating and retrieving data. The goal of CHRONOS (www.chronos.org) is to deliver a dynamic, interactive and time-calibrated framework for Earth system history as a network of comprehensive databases and data files containing information related to the evolution and diversity of life, climate change, geochemical cycles, geodynamical processes, and other aspects of the Earth system. With a "central hub" coordinating a continually expanding network of individual databases and files linked by geologic time, the fast-growing, community-based CHRONOS system serves as a major portal for geological research and outreach, equipped with powerful, interactive analytical and visualization toolkits to enable the exploration and understanding of our evolving planet. With the wealth of existing Earth history data that can be integrated with state-of-the-art information technologies and advanced correlation tools, we also anticipate that the continued implementation of CHRONOS will result in an order of magnitude increase in the precision of global and regional geological time scales, e.g. through the EarthTime project (http://eaps.mit.edu/earthtime/). This alone represents a major advance in Earth system history research and is expected to lead to new insights into the rates and magnitudes of important geological processes, many of which are relevant to understanding Earth system changes influenced by human activity. Beyond facilitating studies of scientific issues of immediate concern, the CHRONOS community is working on educational and community involvement projects by networking information and pedagogical activities on topics of general interest (e.g., evolution, extinction events) in CHRONOSLab. A partner of the "GeoInformatics" initiative, CHRONOS is a multi-institution project funded by the National Science Foundation fostering active international collaborations.

We report on the discriminatory power of different data sets with regard to the classification of sites along the disturbance gradient, using preliminary data accounting for 13 surveys and 142425 arthropods collected by Malaise, pitfall and yellow-pan traps. We compared the performance of different data sets. These were based upon ordinal, familial and guild composition, or upon 22 target taxa sorted to morphospecies and either considered in toto or grouped within different functional guilds. Finally we evaluated `predictor sets' made up of a few families or other target taxa, selected on the basis of their indicator value index. Although the discriminatory power of data sets based on ordinal categories and guilds was low, that of target taxa belonging to chewers, parasitoids and predators was much higher. The data sets that best discriminated among sites of differing degrees of disturbance were the restricted sets of indicator families and target taxa. This validates the concept of predictor sets for species-rich tropical systems. Including or excluding rare taxa in the analyses did not alter these conclusions. We conclude that calibration studies similar to ours are needed elsewhere in the tropics and that this strategy will allow to devise a representative and efficient biotic index for the biological monitoring of terrestrial arthropod assemblages in the tropics.

The largest number of species was mid-sized canopy trees with maximum height 10-20 m and understorey treelets with maximum height of 5-10 m. Several species of understorey treelets in the genera Matisia and Rinorea dominated the forest numerically, while important canopy species were Iriartea deltoidea and Eschweilera coriacea. We examined how species partition local topographic variation into niches, and how much this partitioning contributes to forest diversity. Evidence in favour of topographic niche-partitioning was found: similarity in species composition between ridge and valley quadrats was lower than similarity between two valley (or two ridge) quadrats, and 25% of the species had large abundance differences between valley and ridge-top. On the other hand, 25% of the species were generalists, with similar abundance on both valley and ridges, and half the species had only moderate abundance differences between valley and ridge. Topographic niche-partitioning was not finely grained. There were no more than three distinct vegetation zones: valley, mid-slope, and upper-ridge, and the latter two differed only slightly in species composition. Similarity in species composition declined with distance even within a topographic habitat, to about the same degree as it declined between habitats. This suggests patchiness not related to topographic variation, and possibly due to dispersal limitation. We conclude that partitioning of topographic niches does make a contribution to the alpha -diversity of Amazonian trees, but only a minor one. It provides no explanation for the co-occurrence of hundreds of topographic generalists, nor for the hundreds of species with similar life-form appearing on a single ridge-top.

The rhizosphere was defined as the area immediately adjacent to a root encrusted with Fe(III)-oxides or Fe plaque, and non-rhizosphere soil was >0.5 cm from the root surface. The rhizosphere had a significantly higher percentage of poorly crystalline Fe (66 +/- 7%) than non-rhizosphere soil (23 +/- 7%); conversely, non-rhizosphere soil had a significantly higher proportion of crystalline Fe (50 +/- 7%) than the rhizosphere (18 +/- 7%, P<0.05 in all cases). The percentage of poorly crystalline Fe(III) was significantly correlated with the percentage of FeRB (r=0.76), reflecting the fact that poorly crystalline Fe(III) minerals are labile with respect to microbial reduction. Abiotic reductive dissolution consumed about 75% of the rhizosphere Fe(III)-oxide pool in 4 h compared to 23% of the soil Fe(III)-oxide pool. Similarly, microbial reduction consumed 75-80% of the rhizosphere pool in 10 days compared to 30-40% of the non-rhizosphere soil pool. Differences between the two pools persisted when samples were amended with an electron-shuttling compound (AQDS), an Fe(III)-reducing bacterium (Geobacter metallireducens), and organic carbon. Thus, Fe(III)-oxide mineralogy contributed strongly to differences in the Fe(III) reduction potential of the two pools. Higher amounts of poorly crystalline Fe(III) and possibly humic substances, and a higher Fe(III) reduction potential in the rhizosphere compared to the non-rhizosphere soil, suggested the rhizosphere is a site of unusually active microbial Fe cycling. The results were consistent with previous speculation that rapid Fe cycling in wetlands is due to the activity of wetland plant roots.

On a local scale (less than 1 km), elevated desiccation and wind disturbance near fragment margins lead to sharply increased tree mortality, thus altering canopy-gap dynamics, plant community composition, biomass dynamics and carbon storage. Fragmented forests are also highly vulnerable to edge-related fires, especially in regions with periodic droughts or strong dry seasons. At landscape to regional scales (10-1000 km), habitat fragmentation may have complex effects on forest-climate interactions, with important consequences for atmospheric circulation, water cycling and precipitation. Positive feedbacks among deforestation, regional climate change and fire could pose a serious threat for some tropical forests, but the details of such interactions are poorly understood.

AN - 71963395; 15156916 AB - Bates hypothesized that some butterfly species that are palatable gain protection from predation by appearing similar to distasteful butterflies. When undisturbed, distasteful butterflies fly slowly and in a straight line, and palatable Batesian mimics also adopt this nonchalant behaviour. When seized by predators, distasteful butterflies are defended by toxic or nauseous chemicals. Lacking chemical defences, Batesian mimics depend on flight to escape attacks. Here, I demonstrate that flight in warning-coloured mimetic butterflies and their distasteful models is more costly than in closely related non-mimetic butterflies. The increased cost is the result of differences in both wing shape and kinematics. Batesian mimics and their models slow the angular velocity of their wings to enhance the colour signal but at an aerodynamic cost. Moreover, the design for flight in Batesian mimics has an additional energetic cost over that of its models. The added cost may cause Batesian mimics to be rare, explaining a general pattern that Bates first observed. JF - Proceedings.

We also assessed the influence of several life-history features (wood density, growth form, mortality rate, recruitment rate, stem diameter, growth increment, population density) on tree longevity. Data on 3159 individual trees were collected in 24 permanent, 1ha plots in undisturbed forest arrayed across a large (ca. 1000km super(2)) study area. For each species, three estimates of longevity were generated (by dividing the stem diameter of the largest tree by the median, upper quartile, and upper decile of observed diameter-growth rates), and the mean of these three values was used as a longevity estimate. Longevity values ranged from 48 years in the pioneer Pourouma bicolor (Cecropiaceae) to 981 years for the canopy tree Pouteria manaosensis (Sapotaceae), with an overall mean of 336 plus or minus 196 years. These growth-based estimates of maximum tree age were concordant with those derived from analyses of mean mortality rates. Tree longevity was positively correlated with wood density, maximum stem diameter, and population density, and negatively correlated with annual mortality, recruitment, and growth rates. On average, pioneer species had much lower longevity than did non-pioneers, whereas among old-growth trees, emergent species had greater longevity than did canopy species. Our results are consistent with radiocarbon-based studies that suggest that Amazonian trees can occasionally exceed 1000 years of age.

Here we show that, over the past two decades, forests in a central Amazonian landscape have experienced highly nonrandom changes in dynamics and composition. Our analyses are based on a network of 18 permanent plots unaffected by any detectable disturbance. Within these plots, rates of tree mortality, recruitment and growth have increased over time. Of 115 relatively abundant tree genera, 27 changed significantly in population density or basal area: a value nearly 14 times greater than that expected by chance. An independent, eight-year study in nearby forests corroborates these shifts in composition. Contrary to recent predictions, we observed no increase in pioneer trees. However, genera of faster-growing trees, including many canopy and emergent species, are increasing in dominance or density, whereas genera of slower-growing trees, including many subcanopy species, are declining. Rising atmospheric CO sub(2) concentrations may explain these changes, although the effects of this and other large-scale environmental alterations remain uncertain. These compositional changes could have important impacts on the carbon storage, dynamics and biota of Amazonian forests.

Diversification in bromeliads has been linked to several key innovations, including water- and nutrient-impounding phytotelmata, absorptive epidermal trichomes, and the water- conserving mode of photosynthesis known as crassulacean acid metabolism (CAM). To clarify the origins of CAM and the epiphytic habit, we conducted a phylogenetic analysis of nucleotide sequences for 51 bromeliad taxa by using the plastid loci matK and the rps16 intron, combined with a survey of photosynthetic pathway determined by carbon-isotope ratios for 1,873 species representing 65% of the family. Optimization of character-states onto the strict consensus tree indicated that the last common ancestor of Bromeliaceae was a terrestrial C sub(3) mesophyte, probably adapted to moist, exposed, nutrient-poor habitats. Both CAM photosynthesis and the epiphytic habit evolved a minimum of three times in the family, most likely in response to geological and climatic changes in the late Tertiary. The great majority of epiphytic forms are now found in two lineages: in subfamily Tillandsioideae, in which C sub(3) photosynthesis was the ancestral state and CAM developed later in the most extreme epiphytes, and in subfamily Bromelioideae, in which CAM photosynthesis predated the appearance of epiphytism. Subsequent radiation of the bromelioid line into less xeric habitats has led to reversion to C sub(3) photosynthesis in some taxa, showing that both gain and loss of CAM have occurred in the complex evolutionary history of this family.

AN - 19291858; 7394933 AB - Avian malaria is caused by a diverse community of genetically differentiated parasites of the genera Plasmodium and Haemoproteus. Rapid seasonal and annual antigenic allele turnover resulting from selection by host immune systems, as observed in some parasite populations infecting humans, may extend analogously to dynamic species compositions within communities of avian malarial parasites. To address this issue, we examined the stability of avian malarial parasite lineages across multiple time-scales within two insular host communities. Parasite communities in Puerto Rico and St Lucia included 20 and 14 genetically distinct parasite lineages, respectively. Lineage composition of the parasite community in Puerto Rico did not vary seasonally or over a 1 year interval. However, over intervals approaching a decade, the avian communities of both islands experienced an apparent loss or gain of one malarial parasite lineage, indicating the potential for relatively frequent lineage turnover. Patterns of temporal variation of parasite lineages in this study suggest periodic colonization and extinction events driven by a combination of host-specific immune responses, competition between lineages and drift. However, the occasional and ecologically dynamic lineage turnover exhibited by insular avian parasite communities is not as rapid as antigenic allele turnover within populations of human malaria.

AN - 71705047; 15001783 AB - In the Old World, some mosquitoes in the Culex pipiens complex are excellent enzootic vectors of West Nile virus, circulating the virus among birds, whereas others bite mainly humans and other mammals. Here we show that, in northern Europe, such forms differing in behavior and physiology have unique microsatellite fingerprints with no evidence of gene flow between them, as would be expected from distinct species. In the United States, however, hybrids between these forms are ubiquitous.

AN - 66644520; 15214689 AB - A combination of medetomidine hydrochloride (medetomidine) and ketamine hydrochloride (ketamine) was evaluated in 16 boma-confined and 19 free-ranging impalas (Aepyceros melampus) to develop a non-opiate immobilisation protocol. In free-ranging impala a dose of 220 +/- 34 microg/kg medetomidine and 4.4 +/- 0.7 mg/kg ketamine combined with 7500 IU of hyaluronidase induced recumbency within 4.5 +/- 1.5 min, with good muscle relaxation, a stable heart rate and blood pH. PaCO2 was maintained within acceptable ranges. The animals were hypoxic with reduced oxygen saturation and low PaO2 in the presence of an elevated respiration rate, therefore methods for respiratory support are indicated. The depth of sedation was adequate for minor manipulations but additional anaesthesia is indicated for painful manipulations. Immobilisation was reversed by 467 +/- 108 microg/kg atipamezole hydrochloride (atipamezole) intramuscularly, but re-sedation was observed several hours later, possibly due to a low atipamezole:medetomidine ratio of 2:1. Therefore, this immobilisation and reversal protocol would subject impalas to possible predation or conspecific aggression following reversal if they were released into the wild. If the protocol is used on free-ranging impala, an atipamezole:medetomidine ratio of 5:1 should probably be used to prevent re-sedation.

In this study, we have attempted to duplicate the carbonado microstructure by sintering diamond powders without catalysts in a multi-anvil press at pressures of 6 to 9 GPa, temperatures of 1200 to 1800 degrees C, and times up to 6 h. The resultant microstructural defect assemblages for each experimental condition were characterized by transmission electron microscopy (TEM). Despite the absence of catalysts, sintered compacts were successfully produced for all runs, though intergranular porosity was significantly higher than that observed in natural carbonado. Primary grain sizes were reduced by more than 50% from their original dimensions in some experiments due to surface fracturing and abrasion, and aperiodic slip planes rigorously parallel to {111} consistently emerged in high densities, with lamellar spacings of 3 to 30 nm. In addition, sintering over all conditions produced polysynthetic spinel twinning in close association with the partial slip defects. Compacts compressed at 8 GPa produced some euhedral crystals with very low dislocation densities surrounded by grains in which dislocation densities were quite high. In addition, curviplanar defects loosely constrained to {111} were visible within some specimens sintered at the highest pressures. These textures resembled the polygonalization fabrics and defect microstructures observed in natural carbonado (De et al. 1998), and the appearance of these features suggests that our experiments at their most extreme pressure and temperature parameters reproduced carbonado-like defect assemblages. The formation of such textures in quasi-hydrostatic experiments suggests that shock metamorphism is not required to produce the periodic defect lamellae observed in carbonado.

We also report on a new fossil skull belonging to the podocnemidid turtle Bairdemys sp. Fragmentary material demonstrates the presence of additional shark species and a sirenian. The Cerro La Cruz fauna includes at least 23 species of vertebrates. Earlier fossil discoveries from Cerro La Cruz indicated a near-shore marine environment; the latest discoveries indicate in addition fluvial and terrestrial (perhaps coastal) deposits. Elements of the fauna (including fish of the subfamily Serrasalminae and potentially an odontocete) are consistent with the hypothesis that a tributary and/or delta of the Orinoco existed in this area of north-western Venezuela during early Miocene times.

The homogeneity of oxygen isotopic compositions within and among individual mineral grains has also been examined. Oxygen isotope fractionations between coexisting mineral pairs were utilized in oxygen isotope thermometry. Our measured Delta (super 17) O values, ranging from 0.97 to 1.25 per mil, are characteristic of a single reservoir and fully confirm the oxygen isotopic similarity between IVA irons and L/LL chondrites. Steinbach and Sao Joao Nepomuceno, containing inclusions of two silicate minerals in mutual contact, exhibit a mass-dependent fractionation of (super 18) O/ (super 16) O between tridymite and bronzite with apparent oxygen isotopic heterogeneity. The SiO (sub 2) -bearing member, Gibeon, gives homogeneous oxygen isotopic compositions without detectable fractionation of (super 18) O/ (super 16) O between tridymite and quartz. Oxygen isotope equilibrium temperatures are estimated for coexisting tridymite and bronzite in the same sample slabs or clusters in Steinbach and Sao Joao Nepomuceno. The fractionations of (super 18) O/ (super 16) O between bronzite and tridymite range from 1.6 to 2.3 per mil in different sample slabs or clusters. On the basis of the closure temperature concept, cooling rates are estimated at approximately 20 to 1000 degrees C/Myr between 800 and 1000 degrees C, a range of temperatures not accessible to other cooling rate methods. Using the Fast Grain Boundary diffusion model, we have demonstrated that significant oxygen heterogeneity both in tridymite and bronzite is probably due to isotope exchange during cooling between minerals with various grain sizes and mineral abundances in different regions of the samples. The new estimates of cooling rate by oxygen isotope thermometry refine previous cooling curves of IVA irons and support the breakup-reassembly model for the IVA parent body.

Reaction of Na-rich, residual fluids with earlier formed potassium feldspar, quartz, muscovite, lepidolite, and spodumene, resulted in the replacement of these minerals by fine-grained (saccharoidal) and bladed (cleavelandite) albite. The replacement of pre-existing minerals by albite may not be readily obvious with the unaided eye, but can be easily identified using cathodoluminescence (CL). The principle CL feature that is observed in albite from Black Mountain is the reduction of luminescence, which varies from a bright green to blue in non-replacing albite to dark green luminescence in albite that replaces other minerals. The mechanism by which this occurs is still not known, but a few hypotheses have been proposed: 1) the incorporation of a quenching agent in the albite during the replacement process 2) the reduction of activators (Ti (super 4+) , Mn (super 2+) , Fe (super 2+) , Fe (super 3+) ) in albite during the breakdown of replaced minerals, and 3) an increase in the amount of activating elements leading to concentration quenching in the albite.

Dating is less certain in Western Australia, but the fossils are in excess of 1 billion years. Specimens from both areas are informally termed "string of beads", and differences are currently judged to be at the species level. In the Montana species seemingly alternate beads episodically disappear, for the ratio of bead size to spacing is nearly constant, allowing for some individual variation among strings. In the Western Australia species, seemingly there is no loss of beads, but the beads are not so large as some from Montana. Both species occur in sandstone, but the Montana sandstone is finely laminated and no such lamination occurs in the Australian outcrops. Both may have lived in relatively well-oxygenated water, with the Montana occurrence in quieter water. The organisms cannot be certainly assigned to either "plants" or "animals," though the latter interpretation is preferred by us. In either assignment, they suggest that coloniality appeared early in the geologic record. As indicated by widespread distribution in Western Australia, this genus may have utility as a guide fossil in ancient clastic strata which are essentially barren of fossils.

An enrichment protocol yielded 150 positive clones. We designed primers to amplify 17 unique (GT) sub(n) microsatellites, eight of which amplified cleanly and were polymorphic. A survey of 29 individuals showed that these loci are highly variable with the number of alleles ranging from seven to 19 and expected heterozygosity ranging from 0.66 to 0.93. These markers will be useful for studies of population structure and intraspecific variation in epidemiological characteristics of Cx. pipiens.

The foodplant in all cases was Schoepfia schreberi (Olacaceae). Only six of the 219 individual caterpillars and pupae collected during the last 15 yr were parasitized by braconid and chalcid wasps and a tachinid fly. The larval ultrastructure of C. sturnula was studied by means of scanning electron microscopy, with emphasis placed on their prothoracic balloon setae, rare structures in the Riodinidae. The occurrence of larval and pupal balloon setae in the Riodinidae is reviewed. Larval balloon setae are currently known from all three genera of the Helicopini, at least Calydna in the incertae sedis section of the Riodininae, and at least three genera of the Nymphidiini. Larval material was examined for all but one of these genera, and the macro and ultrastructure of their balloon setae are described, illustrated, and compared. Pupal balloon setae are currently known only from Helicopis and Calydna . The balloon setae of Calydna and the genera of the Helicopini are found to be more similar to each other than to those of the Nymphidiini genera. Because balloon setae occur in nonmyrmecophilous (such as Calydna ) as well as myrmecophilous species, we hypothesize that they are used to store and disperse a noxious chemical when the caterpillar or pupa is grabbed by a predator, rather than to facilitate a symbiotic relationship with ants, as previously suggested. Internally, balloon setae are filled with a spongy yellowish material that consists of a dense latticework of tiny strands. We suggest that as these strands enter the otherwise hollow external acanthae, the acanthae discharge the noxious chemical when the balloon setae are squeezed.

Kaieteur National Park is located on eastern edge of the Potaro Plateau in central Guyana, South America. The species examined have distributions that vary from local to global. The distribution patterns of the families, genera and species known from Kaieteur are examined using generalized distribution patterns. Data on distribution patterns, elevation and habitat were gathered from 131 flowering plant families, 517 genera and 1227 species. These plants represent all taxa that are currently known to occur in the area of the original Kaieteur National Park. Families tend to have cosmopolitan or pantropical distribution, genera are mostly neotropical and at the species level, most species are restricted to the Guiana Shield (c. 40%), northern South America (69%) or neotropical (96%) in distribution, each level inclusive of the previous. The flora at the study site in Kaieteur National Park has its strongest affinity with the Guiana Shield; 42.1% of the species have a distribution that corresponds with the Shield or is more restricted within the Shield. There is a distinct flora on the Guiana Shield and its affinities lie with the flora of northern South American and beyond that, the neotropics. The flora is not closely affiliated with the floras of the Brazilian Shield, the Amazon, the Andes, the eastern coastal forests of Brazil, southern South America, or Africa as has been previous suggested.

The Hawaiian Islands are isolated in the North Pacific Ocean nearly 4000 km from the nearest continent and nearly as distant from the closest high islands, the Marquesas. The range of island sizes, environments, and geological histories within an extremely isolated archipelago make the Hawaiian Islands an ideal system in which to study spatial variation in species distributions and diversity. Because the biota is derived from colonization followed by extensive speciation, the role of evolution in shaping the regional species assemblage can be readily examined. For whole islands and regions of each major habitat, species-area relationships were assessed. Residuals of species-area relationships were subjected to correlation analysis with measures of endemism, isolation, elevation and island age. Putative groups of descendents of each colonist from outside the Hawaiian Islands were considered phylogenetic lineages whose distributions were included in analyses. The species-area relationship is a prominent pattern among islands and among regions of each given habitat. Species number in each case correlates positively with number of endemics, number of lineages and number of species per lineage. For mesic and wet habitat regions, island age is more influential than area on species numbers, with older islands having more species, more single-island endemics, and higher species : lineage ratios than their areas alone would predict. Because species numbers and endemism are closely tied to speciation in the Hawaiian flora, particularly in the most species-rich phylogenetic lineages, individual islands' histories are central in shaping their biota. The Maui Nui complex of islands (Maui, Moloka'i, Lna'i and Kaho'olawe), which formed a single large landmass during most of its history, is best viewed in terms of either the age or area of the complex as a whole, rather than the individual islands existing today.

However, the role of behaviour in this ecomorphological paradigm is not well defined. We investigated the relationship between morphology, ecology and escape behaviour among 25 species of the lizard clade Liolaemus in a phylogenetic framework. We demonstrate that the relationship between morphology and characteristics of habitat structure shows little or no association, consistent with a previous study on this group. However, a significant relationship was found between morphology and escape behaviour with the distance a lizard moved from a potential predator correlated with body width, axilla-groin length, and pelvis width. A significant relationship between escape behaviour and habitat structure occupation was found; lizards that occupied tree trunks and open ground ran longer distances from predators and were found greater distances from shelter. Behavioural strategies used by these lizards in open habitats appear to have made unnecessary the evolution of limb morphology that has occurred in other lizards from other clades that are found in open settings. Understanding differences in patterns of ecomorphological relationships among clades is an important component for studying adaptive diversification.

We tested whether polyandrous female side-blotched lizards, Uta stansburiana, would adjust within-clutch progeny investment according to sire phenotypes. In two different years, polyandrous females selectively used sperm from larger sires to produce sons and used sperm from smaller sires to produce daughters. This cryptic sperm choice had significant effects on progeny survival to maturity that were consistent with sexually antagonistic effects associated with sire body size. Large sires produced sons with high viability and small sires produced daughters with high viability. These results are consistent with our previous findings that alleles for male body size have different fitness effects in male and female progeny. Breeding experiments in the laboratory indicate that results from the wild are more likely due to female choice than biased sperm production by males. Our results demonstrate highly refined gender-specific female choice for sperm and indicate that sire body size may signal the quality of sons or daughters that a sire will produce.

We used a streptavidin subtractive enrichment technique to develop a library of CA/GT repeats. Eight loci were screened for diversity from 96 individuals from Barro Colorado Island (BCI) and neighbouring Gigante peninsula in Panama. Luehea seemannii shows moderate levels of genetic diversity within these two populations. Allelic richness ranged from four to nine alleles and averaged 6.44 alleles per locus. Average expected heterozygosity was 0.65 on BCI and 0.60 on Gigante. Results are compared to microsatellite data from another wind-dispersed gap colonizing species common in Panama.

The monkey strips bark from the cedar in order to feed on the tissue beneath. Although identified as threatened species, the monkeys are nevertheless villainized. Researchers, however, dispute the damage caused by the monkeys, arguing that they are in fact victims of poaching, water and food shortages. The forest declines are blamed instead on logging, parasitic infestation, and tree disease caused by drought. Human demands on aquifers are also problematic. The single greatest problem are the goats and sheep herded by nomadic Berber shepherds, which have stripped the vegetation on their grazed lands.

The canal was constructed under President Theodore Roosevelt as a means to shorten the distance between the Pacific and Atlantic oceans, and thus allow the US to increase its naval strength. The engineering feats of the canal, which cuts through the mountains with a series of locks, have been maintained over time with highly trained specialists. Over time sophisticated tracking systems have been installed. The canal operations were privatized in 1998, a transition which has affected ports, utilities, and the transportation infrastructure. Ecotourism is a growing interest in this biologically rich tropical ecosystem.

These figures depend on the assumption that genera and families spanning the two provinces belong to the same lineages (that is, they are monophyletic). Here we show that this assumption is incorrect on the basis of analyses of mitochondrial and nuclear genes. Pervasive morphological convergence at the family level has obscured the evolutionary distinctiveness of Atlantic corals. Some Atlantic genera conventionally assigned to different families are more closely related to each other than they are to their respective Pacific 'congeners'. Nine of the 27 genera of reef-building Atlantic corals belong to this previously unrecognized lineage, which probably diverged over 34 million years ago. Although Pacific reefs have larger numbers of more narrowly distributed species, and therefore rank higher in biodiversity hotspot analyses, the deep evolutionary distinctiveness of many Atlantic corals should also be considered when setting conservation priorities.

The traces of canopy height in these stands revealed structural characteristics such as cover, maximum and mean heights which were consistent with corresponding ground measurements. Differences in the statistics on canopy structure corresponded to general developmental trends in these stands, including the development of maximum height and surface rugosity. Furthermore, some of the outer canopy statistics related to measures of internal organization, such as the shape of the foliage height profile and the leaf area index. These observations suggest that such measurements could be used readily to classify stand structure and developmental stage, and to deduce some aspects of internal organization of vegetation.

We sequenced mtDNA of recent and historical samples from 45 wolves from throughout lowland peninsular India and 23 wolves from the Himalayas and Tibetan Plateau and compared these sequences with all available wolf and dog sequences. All 45 lowland Indian wolves have one of four closely related haplotypes that form a well-supported, divergent sister lineage to the wolf-dog clade. This unique lineage may have been independent for more than 400 000 years. Although seven Himalayan wolves from western and central Kashmir fall within the widespread wolf-dog clade, one from Ladakh in eastern Kashmir, nine from Himachal Pradesh, four from Nepal and two from Tibet form a very different basal clade. This lineage contains five related haplotypes that probably diverged from other canids more than 800 000 years ago, but we find no evidence of current barriers to admixture. Thus, the Indian subcontinent has three divergent, ancient and apparently parapatric mtDNA lineages within the morphologically delineated wolf. No haplotypes of either novel lineage are found within a sample of 37 Indian (or other) dogs. Thus, we find no evidence that these two taxa played a part in the domestication of canids.

Shock-produced planar microstructures (PMs) have been identified in quartz grains in several lithologies associated with the structure: sandstones, quartzite pebbles, and breccia. Two distinct types of PMs are present: P1 features, which appear identical to planar fractures (PFs or cleavage), and P2 features, which are interpreted as possible incipient planar deformation features (PDFs). The latter are uniquely produced by the shock waves associated with meteorite impact events. Both types of PMs are oriented parallel to specific crystallographic planes in the quartz, most commonly to c(0001), xi {1122}, and r/z{1011}. The association of unusual, structurally deformed strata with distinct shock-produced microdeformation features in their quartz-bearing rocks establishes Rock Elm as a meteorite impact structure and supports the view that the presence of multiple parallel cleavages in quartz may be used independently as a criterion for meteorite impact. Preliminary paleontological studies indicate a minimum age of Middle Ordovician for the Rock Elm structure. A similar age estimate (450-400 Ma) is obtained independently by combining the results of studies of the general morphology of complex impact structures with estimated rates of sedimentation for the region.

Ecologists address these issues using small-scale experiments and by monitoring modern communities. The fossil record, however, preserves the results of far larger natural experiments on the effect of environmental changes on fossil assemblages. Leonardian and Guadalupian rocks of the Glass Mountains (west Texas) record sea-level changes at several orders of magnitude and also contain exceptionally well-preserved silicified brachiopod faunas. The collections from this region, made by G. A. Cooper and R. Grant over several decades, are large and diverse (855,047 specimens; 512 species; 142 genera; 191 localities), providing a robust statistical sample. All fossil material analyzed in this study was extracted by acid dissolution of the carbonate rock matrix. The resulting bulk samples allowed description and identification of fossil material at a high level of taxonomic resolution and consistency due to the excellent preservation of silicified specimens and are also appropriate for analysis of species abundances. The succession includes four third-order depositional sequences, each with its own distinctive suite of species but a similar range of carbonate ramp habitats. In addition, the interval records a second-order rise and fall in sea level (recorded by the stacking pattern of the third-order sequences). Application of a neutral model of biodiversity indicates that landscape-scale ecological dynamics changed in concert with second-order sea level change: higher sea level coincided with greater connectivity of local communities in the region as well as higher rates of species replacement by speciation. The observed patterns suggest that ecological communities can accommodate changes in environment, associated with second-order fluctuations in sea level in this case, through adjustments in rates of species production and immigration while remaining diverse in terms of taxonomic and functional composition.

This paper explores morphological and environmental taphonomic gradients in six crinoid morphotypes (diplobathrids, monobathrids, dichocrinids, platycrinitids, cladids, and flexibles) from three stratigraphic units (the Maynes Creek Formation and the Starrs Cave and "Ollie" Members of the Wassonville Formation) representing distinct depositional environments along an onshore-offshore transect within the Early Mississippian (Kinderhookian) Wassonville Cycle of southeast Iowa. Taphonomic differences in stalk, calyx, and arm disarticulation, calyx compression, and arm orientation were categorized independently and subjected to a non-parametric ranking test with bootstrapping (rather than a parametric approach, due to the non-additive nature of the data analyzed herein) to explore taphonomic patterns. The results suggest that the disarticulation of the stalk, calyx, and arms behave independently, although patterns of arm disarticulation may be influenced by the disarticulation of the calyx. In general, preservational integrity in fossil crinoids appears to be a function of the relative proportion of articular to non-articular surface area, skeletal innovations, tissue type and properties, survival response behavior, and thickness and rapidity of burial. Furthermore, these results demonstrate a general decrease in preservational integrity from onshore to offshore environments in the Wassonville Cycle and that sedimentation dynamics associated with episodic events are more influential than background deposition in determining preservation in fossil Lagerstatten. The methodology employed herein also could be used effectively to identify morphological, behavioral, and environmental taphonomic influences on other fossil organisms.

We fertilized dwarf trees in Almirante Bay, Bocas del Toro Province, north-eastern Panama with nitrogen (N) and phosphorus (P) to determine (1) if growth limitations are due to nutrient deficiency; and (2) what morphological and/or physiological factors underlie nutrient limitations to growth. Shoot growth was 10-fold when fertilized with P and twofold with N fertilization, indicating that stunted growth of these mangroves is partially due to nutrient deficiency. Growth enhancements caused by N or P enrichment could not be attributed to increases in photosynthesis on a leaf area basis, although photosynthetic nutrient-use efficiency was improved. The most dramatic effect was on stem hydraulic conductance, which was increased sixfold by P and 2.5-fold with N enrichment. Fertilization with P enhanced leaf and stem P concentrations and reduced C : N ratio, but did not alter leaf damage by herbivores. Our findings indicate that addition of N and P significantly alter tree growth and internal nutrient dynamics of mangroves at Bocas del Toro, but also that the magnitude, pattern and mechanisms of change will be differentially affected by each nutrient.

Curtailing these trends might be facilitated by (i) reducing rates of habitat loss and degradation, (ii) enhancing systematics and (iii) increasing the flow of primary information on tropical biodiversity. We emphasize the need to examine alternative approaches that could generate a constant stream of data from tropical ecosystems. We argue that data collecting by parataxonomists (local assistants trained by professional biologists) represents one of the most efficient approaches to the study of tropical ecosystems available to date. Parataxonomists can provide high-quality biological specimens and ecological information; statistical power will be high due to large sample sizes of data; database growth will be rapid and results will be published in a timely manner; and there will be collateral education of local people in conservation biology by the parataxonomists themselves. We stress that training local parataxonomists to inventory and monitor biodiversity is a promising and efficient strategy that deserves more attention in conservation biology. In particular, it may be one of the most feasible approaches for the biological monitoring of small and cryptic organisms in species-rich environments, such as invertebrates in tropical rain forests. Synthesis and applications. Permanent botanical plots yield a wealth of data on the organization of tropical forests, and their numbers should be increased to monitor tropical biodiversity. Likewise, augmenting the number of local parataxonomist groups in various tropical countries and networking these contingents to monitor functionally diverse taxa may provide an efficient biological monitoring system in tropical forests.

However, our ability to make strong inferences about vegetation-environment linkages in field studies is often limited due to correlations among environmental variables, spatial autocorrelation, and scale dependency of observations. This is particularly true in large, heterogeneous ecosystems such as the Everglades. Here, an extensive canal-and-levee system has modified historical fire regimes and hydropatterns while contributing large inputs of surface-water phosphorus (P), nitrogen (N) and cations such as sodium (Na). Some of these anthropogenic influences have been implicated as factors leading to the shift of sawgrass (Cladium jamaicense Crantz) and slough communities to an assemblage of weedy species such as cattail (Typha domingensis Pers.). To untangle the independent effect of multiple variables, we used a spatially explicit, multivariate approach to identify linkages among spatial patterns, environmental factors, and vegetation composition along a 10-km gradient of anthropogenic influence in the Everglades, an area immediately downstream from canal inflow structures. Clusters of plots were stratified among three zones (Impacted, Transition, and Reference), a design that allowed us to contrast vegetation-environment linkages and spatial patterns at multiple scales and degrees of ecosystem alteration. Along the 10-km gradient, partial Mantel tests showed that nutrients (phosphorus, nitrogen, and potassium) and hydropattern (frequency of dryness) were independently linked to patterns in fine-scale vegetation composition, but phosphorus was the only environmental variable linked to patterns of coarse-scale composition. Regardless of scale, the effect of distance from canal inflows accounted for variation in vegetation that could not be explained by other variables. A significant residual effect of spatial proximity among sampling locations also was detected and was highly suggestive of dispersal or other spatial determinants of vegetation pattern. However, this pure spatial effect was significantly stronger in the Transition and Impacted zones than in the Reference zone - fine-scale environmental variables explained all of the spatial structure in vegetation in the Reference zone. A further examination of spatial patterns in vegetation by using Mantel correlograms revealed significant heterogeneity at fine, local scales in the Reference zone, but this pattern progressively degraded toward homogeneity among closely neighboring locations in the Impacted zone. However, the fine-scale vegetation pattern in the Reference zone was hierarchically nested at a broader scale and yielded a similar coarse pattern across the landscape, whereas the coarse pattern in the Transition and Impacted zones was relatively heterogeneous and fragmented. Collectively, these results indicate that allogenic spatial and environmental factors related to the canal system have disrupted the coupling between pattern and process by altering fine-scale vegetation-environment linkages and spatial patterns characteristic of the natural Everglades ecosystem.

However, plant fitness responses to rising CO sub(2) should also include quantitative measures of reproduction, since most forest systems are recruitment limited. Until now, it has proved very difficult to grow forest trees to sexual maturity in a CO sub(2)-enriched environment. This paper is the first of its kind to address the effects of elevated CO sub(2) on the reproduction of hardwood trees in a natural forest. Beginning in 1996, scrub-oak vegetation, predominantly three species of scrub-oaks, Quercus myrtifolia, Q. chapmanii, and Q. geminata, were grown inside eight chambers with elevated CO sub(2) (704 parts per million (ppm)) and eight with ambient CO sub(2) (379 ppm) at Kennedy Space Center, Florida. In elevated CO sub(2), acorn production increased significantly for the dominant species Q. myrtifolia and for Q. chapmanii, but it did not increase for the subdominant, Q. geminata. Acorn weight, germination rate, and predation by weevils were unaffected by CO sub(2). Thus, recruitment of some forest tree species into the Florida scrub-oak community is likely to be accelerated in an atmosphere of increased CO sub(2). However, because the acceleration of recruitment differs among species, over the long term, Q. myrtifolia and Q. chapmanii will be favored over Q. geminata and this is likely to change patterns of species diversity.

A 17-Year Record from Panama AN - 17889390; 5857928 AB - The relative importance of large lianas (woody vines) increased by 100% for stem enumerations conducted during the 1980s and 1990s in widely scattered Neotropical forests. We use three independent types of data to evaluate the hypothesis that lianas have increased in importance in old growth forests on Barro Colorado Island, Panama. Liana leaf litter production and the proportion of forest-wide leaf litter composed of lianas increased between 1986 and 2002. In contrast, liana seed production and liana seedling densities were much more variable through time with particularly high levels during and immediately after El Nino years. Longer time series will be required to detect shifts in life-form composition for highly dynamic seed and seedling communities. The Barro Colorado Island leaf production data are, however, consistent with the hypothesis that lianas are increasing in importance in Neotropical forests.

Despite their profound historic and religious significance, these temples are encroached upon by both the jungle and human settlement. Massive roots of ficus trees are slowly bringing down part of the temple, and are the challenge faced by conservators of the World Monuments Fund, who have been working on restoration wince 1989. Angkor Wat has opened to the international community only since the fall of the Khmer Rouge and its loyalists. The restoration and development of this important site is the subject of many speculative proposals, capitalizing on the growing tourist trade. Restoration issues include the selection of appropriate materials and methods.

Regulations limiting development and boating access are intended to protect this gentle marine mammal. Manatees are slow animals in all respects--feeding, movement, and reproduction included. As such they are vulnerable to boaters' collisions and incursions. Once hunted for their meat, the extinction of the species seemed imminent even in the late 19th century. Early photographic studies of the manatee document the scarred results of accidents. The gradual increase in the population over the past 30 years is attributed to improvements in water quality and protective speed limits.

These single-celled algae convert carbon dioxide to food, and release oxygen as a byproduct. Their silica shells are fossilized to become diatomaceous earth, used in filtration and polishing systems, and as fillers in various products. The shape of the shell optimizes carbon dioxide intake and processing by maximizing photosynthesis. With a life span of six days, the dead diatoms accumulate, with their load of carbon, in the sea floor.

I show that four overtly realized arguments in a single clause, although a formal possibility, are strongly disfavored in practice. I suggest that this is due in part to the strain placed on interpretation in cases where two overt second objects - two overt arguments neither of which is inflected on the verb - occur in the same clause. I show that cases of three overt arguments in a clause (subject, object, & second object) are rare but not unknown & that cases of two overt arguments in a clause (subject & object, subject & second object, or object & second object) are relatively common. I show that in 22 cases of three overt arguments per clause, eight of the 24 possible orders of verb, subject, object, & second object are attested. I show that in 1,279 cases of two overt arguments per clause, 20 of the 21 possible orders & combinations of verb, subject, object, & second objects are attested. Also, 24 of the 27 possible orders & combinations of verb, animate proximate, animate obviative, & inanimate are attested.

In a predominantly concatenative system of discrete affixes combined by morphophonemic rules, three types of nonconcatenative suffixation are identified: (1) internally segmentable suffixes derived prior to concatenation; (2) combined pronoun & mode suffixes, which are partly segmentable although not all the resulting morphs can be identified with morphemes; & (3) fused secondary suffixes in a relation of ad hoc substitution or paradigmatic analogy to sequences of primary suffixes. The analysis provides the formal marking of 32 modes, submodes, & suborders comprised in the independent, conjunct, & imperative orders of the Meskwaki verb. 1 Appendix, 14 References. J.

Some of the CAIs were melted prior to aggregation into AOAs and experienced formation of Wark-Lovering rims. Before and possibly after the aggregation, melilite and spinel in CAIs reacted with SiO and Mg of the solar nebula gas enriched in (super 16) O to form Al-diopside and anorthite. Forsterite in some AOAs reacted with (super 16) O-enriched SiO gas to form low-Ca pyroxene. Some other AOAs were either reheated in (super 16) O-poor gaseous reservoirs or coated by (super l6) O-depleted pyroxene-rich dust and melted to varying degrees, possibly during chondrule formation. The most extensively melted AOAs experienced oxygen isotope exchange with (super I6) O-poor nebular gas and may have been transformed into magnesian (Type I) chondrules. Secondary mineralization and at least some of the oxygen isotope exchange in AOAs from altered and metamorphosed chondrites must have resulted from alteration in the presence of aqueous solutions after aggregation and lithification of the chondrite parent asteroids.

Aspects of volcanic landform construction, island subsidence, and erosion were modeled to reconstruct the physical history of this complex. This model estimates the timing, duration, and topographic attributes of different island configurations by accounting for volcano growth and subsidence, changes in sea level, and geomorphological processes. The model indicates that Maui Nui was a single landmass that reached its maximum areal extent around 1.2 Ma, when it was larger than the current island of Hawai'i. As subsidence ensued, the island divided during high sea stands of interglacial periods starting around 0.6 Ma; however during lower sea stands of glacial periods, islands reunited. The net effect is that the Maui Nui complex was a single large landmass for more than 75% of its history and included a high proportion of lowland area compared with the contemporary landscape. Because the Hawaiian Archipelago is an isolated system where most of the biota is a result of in situ evolution, landscape history is an important determinant of biogeographic patterns. Maui Nui's historical landscape contrasts sharply with the current landscape but is equally relevant to biogeographical analyses.

How many species will emigrate into the future is, of course, unknown. If we treat a slice of time in the past as representing the "present", older geologic time-slices as the past and younger geologic time-slices as the "future", four components are recognizable. The I's can be divided into immigrants which become emigrants, IE, and immigrants which become extinct, IX; while the O's are those originating that emigrate, OE, and those originating which become extinct, OX. Thus, the total number of species observed is S = IE+IX+OE+OX. The "future" consists of emigrants in time, E = IE+OE. The question arises as to whether or not information gleaned from such an approach is transferable to modern communities. With this in mind, we selected five Cenozoic time-slices and examined these four components of benthic foraminifera in the Salisbury-Albemarle Embayment (SAE) of the North American Atlantic coastal plain. In all the fossil communities the species are distributed about equally (+ or -10%) between O and I components. The OX component averages about half of the O species and are often rare. These species can be regarded as failed "evolutionary trials" and are a minimum estimate for extinction. Of the five fossil communities, three are balanced where OE = IX so that I = E and the total number of extinctions is TX = IX+OX = O. In balanced communities all of the components can easily be predicted, if one is known. In the two unbalanced communities, OE>IX so that E>I. In these two cases, IX is small and, consequently, TX nearly equal OX. Based on our observations of the fossil foraminiferal communities of the SAE, we would predict that about half of the observed species in a modern community will be extinct within two to three million years. A minimum estimate, the OX component, constitutes about a quarter of the observed species. While many of the OX species occur rarely, survivorship of species with a fossil record (I) cannot be predicted on the basis of abundance. Consideration of the time slices also indicates that the local foraminiferal community depends on continual transfer of species into and out of a regional species pool. Consequently, if other organisms behave like foraminifera, any conservation efforts must be directed toward a large geographic area.

The subaerial deposit covers approximately 390 km (super 2) ; inclusion of a possible additional approximately 150 km (super 2) submarine component gives an estimated volume of 16+ or -5 km (super 3) . Hummocks are present to beyond the coastline but are most prominent in four clusters corresponding to the location of buried bedrock ridges. Bulking in distal portions incorporated accessory Tertiary-to-Quaternary volcaniclastic rocks and ignimbrites. Modern Santa Ana volcano was constructed within the collapse scarp, visible only on its northwest side, following an apparent transition in eruptive style. More than 286,000 people, the country's main port, and important agricultural land now overlie the Acajutla debris-avalanche deposit, which is one of only a few in Central America to exceed 10 km (super 3) in size. Because major edifice failures are high-impact, low-frequency events, the probability of a future Acajutlascale collapse is very low. However, a collapse even an order of magnitude smaller in volume from modern Santa Ana volcano would impact heavily populated areas. The Acajutla failure was perpendicular to a NW-trending fissure system cutting across Santa Ana volcano, which may also influence future failure orientations. The current structure of Santa Ana volcano suggests that future collapses are most likely to the southwest, but the possibility of northward failures cannot be excluded.

At that time, the topic of gravitative flows was gaining momentum, and various theories on underwater avalanches, including turbidity currents capable of carrying coarse sand to the deep sea, had already been proposed. However, these transport processes still needed considerable clarification. Discoveries, including the identification of the sandstones as turbidites by Faure-Muret and others in 1956, were not conceived in a vacuum, but rested on many years of previous research by numerous geologists. Some of the key earlier findings are cited here. My interests then, and for several decades afterward, were focused on the broader context of sedimentary petrology, downslope-to-deep marine deposition, palaeogeography and regional structural geology pertaining to these spectacular Tertiary sequences. Now that more than 40 years have passed, I look back and can better appreciate the role of others and their influence serving as a base for my modest effort. The "cutting of teeth" experiences on the Gres d'Annot were truly fortunate, not only for my early formation as a sedimentologist, but also as I have continued to pursue related and progressively more diverse activities.

Dominant elements were conifers, callipterids and the pteridosperm Sphenopteridium, all plants usually associated with indicators of seasonal moisture regimes. More generally, the Virgilian-Wolfcampian transition was a time of change from dominance of the tropical landscape by floras rich in tree ferns, pteridosperms, and lycopsids, to one dominated by conifers, peltasperms, and cycadophytes. The two types of floras do appear to have overlapped, but possibly in a manner reflective of local landscape heterogeneity. At Carrizo Arroyo for example, the wetland elements are rare and fragmentary, indicating local transport, most likely from wet microhabitats proximate to the site of deposition. Local environmental heterogeneity appears to have been part of larger scale heterogeneity in the region, probably reflective of climatic and edaphic differences in this tectonically active area.

We quantified sediment nutrient accumulation in TFMs upstream and downstream of a proposed water withdrawal project on the Mattaponi River, Virginia. Our goal was to assess nutrient availability by comparing relative rates of carbon (C), nitrogen (N), and phosphorus (P) accumulated in sediments with the C, N, and P stoichiometries of surface soils and above ground plant tissues. Surface soil nutrient contents (0.60-0.92%N and 0.09-0.13%P) were low but within reported ranges for TFMs in the eastern US. In both marshes, soil nutrient pools and C, N, and P stoichiometries were closely associated with sedimentation patterns. Differences between marshes were more striking than spatial variations within marshes: both C, N, and P accumulation during summer, and annual P accumulation rates (0.16 and 0.04 g Pm (super 2) year (super -1) , respectively) in sediments were significantly higher at the downstream than at the upstream marsh. Nitrogen:P ratios <14 in above ground biomass, surface soils, and sediments suggest that N limits primary production in these marshes, but experimental additions of N and/or P did not significantly increase above ground productivity in either marsh. Lower soil N:P ratios are consistent with higher rates of sediment P accumulation at the downstream site, perhaps due to its greater proximity to the estuarine turbidity maximum.

The validity of Menodus giganteus depends on an ultimate understanding of Chadronian brontothere species-level diversity. Although Chadronian brontotheres have historically been split into a multitude of species (N = 47, by 1929), based primarily on horn variation, a preliminary analysis of Chadronian brontothere morphometric data reveals that most of the variation in their horns can be explained by sexual dimorphism. We are not able to objectively group Chadronian brontothere specimens into discrete morphological units with our morphometric data. Variation is apparently continuous among those variables that were commonly used to diagnose Chadronian brontothere species. Chadronian brontotheres can be unambiguously grouped into no more than two discrete morphological units, a group with unbifurcated horns that includes the vast majority of specimens, and a much smaller group with bifurcated horns. If these groups represent valid taxa, Menodus giganteus is a nomen dubium. Megacerops coloradensis Leidy, 1870 is the earliest Chadronian brontothere name whose holotype includes a pair of unbifurcated horns, and is therefore the valid name for the more common species. The rare species with bifurcated horns is Megacerops kuwagatarhinus Mader and Alexander, 1995.

The jaws do not belong to typical Chadronian brontotheres such as Menops, Brontops, or Megacerops (sensu Mader, 1989 = Megacerops coloradensis sensu Mihlbachler et al., this volume) but could belong to Duchesneodus primitivum (Lambe) or Protitanops curryi (Stock). The skull most likely belongs to Menodus heloceras (= Megacerops coloradensis in part sensu Mihlbachler et al., this volume) but we cannot completely rule out the possibility that the skull belongs to the same species to which the mandibles belong. Although the specific taxonomic identity of these specimens is not certain, the brontothere material and the other mammals from the Big Sand Draw Sandstone Lentil suggest an early Chadronian age.

Kiinkerishella zaisanica Gabuniya & Biryukov is known from a dentary fragment with m3 from the upper part of the Aksyir svita and appears to be a dyspternine. Oboia argillaceous Gabuniya from the Kusto svita is known from a dentary fragment with p4-m1 and appears to be a pantolestine. Kiinkerishella and Oboia thus extend the modest diversification of pantolestans during the late Eocene (Ergilian) from Western Europe into Central Asia and are evidence of the paleobiogeographic continuity of land-mammal faunas across Eurasia during the late Eocene.

Although he recognised a sharp contrast between marine faunas of the late Miocene and those of the earliest Pliocene, it was his aid to others, including the present author, which led to the identification of the sudden establishment of oceanic conditions in the Zanclean, and the continued presence of deep basins. This is a story about that influence... and as well about Giuliano, the scientist of his time as I saw him.

The skull, like the postcranial skeleton, has defining pangolin characters imposed on a morphology that is otherwise quite generalized and primitive. The absence of teeth in Patriomanis reinforces its close relationship to living pangolins, but also means that some morphologic information that might have shed light on the question of pangolin origins is absent.

Both have metasomatic origins that are intimately connected with their host serpentinite bodies and convergent-margin petrotectonics. Amphibole jade is nephrite, a tremolite-actinolite rock with a felted, microcrystalline habit; pyroxene jade is jadeite rock (jadeitite), which varies from micro- to macrocrystalline textures. Most nephrite occurs along fault contacts between serpentinite and mafic to felsic igneous rocks or metagraywacke in obduction settings. It forms by Ca- and Si-rich, aqueous fluid-mediated metasomatic replacement of serpentinite, typically antigorite, at greenschist-facies or lower P-T conditions. Other nephrite bodies reflect contact metasomatic replacement of dolomite by Si-rich aqueous fluids during felsic pluton emplacement. Like most nephrite, jadeitite is hosted by antigorite-dominated serpentinite bodies. However, these serpentinites are associated with HP/LT metamorphic terranes, in which jadeitite occurs as isolated tabular bodies or tectonized blocks. Based on textural evidence, particularly clear from cathodoluminescence studies, nearly all jadeitite bodies appear to have formed originally as vein crystallization of an aqueous fluid, most readily interpreted as Na-Al-Si-rich fluid at HP/LT conditions in subduction/collisional settings. The host serpentinite influences jadeitite compositions by lowering fluid aSiO (sub 2) during serpentinization, and contributing Ca+Mg + or - Cr to late-stage jadeitite-forming fluids. Thus, although both types of jade form in convergent-margin tectonic settings, jade has two distinct primary modes of origin: (1) by siliceous replacement of already serpentinized ultramafic rock at low-P, low- to moderate-T conditions following obduction (nephrite); or (2) by the interaction of serpentinizing peridotite and Na-Al-Si fluids at HP/LT conditions during active subduction/collision (jadeitite).

The supracrustal rocks in the Meadowbank area consist of a thick sequence of intermediate-composition volcanic rocks with intercalated iron formation, ultramafic volcanic rocks, and quartzite to quartz arenite. U-Pb geochronology gives an interpreted age of 2711+ or -3 Ma for the host strata at Meadowbank. The intermediate volcanic rocks are predominately volcaniclastic and have a geochemical composition that is consistent with an active continental margin setting. Iron formation deposition was coeval with the intermediate volcanism, as indicated by incorporation of volcanic detritus in the chemical precipitate. The geochemistry of the iron formation indicates that it precipitated from a fluid that at one time was at high temperature (>250 degrees C), reducing, and likely acidic. Intercalated ultramafic rocks rarely show spinifex textures and have trace element ratios that are consistent with mantle plume-related undepleted mantle asthenosphere, likely recording episodic mantle upwelling associated with rifting in an active continental margin. The contact between the ultramafic volcanic rocks and the overlying quartz arenite is a disconformity marked by a quartz pebble conglomerate. However, similar geology on the structural hanging wall and footwall of the contact suggests that the conglomerate does not represent a significant hiatus in deposition, and is more likely a prograding terrigenous siliciclastic unit. Three metamorphic events are recognized. The first, M (sub 1) , is a cryptic greenschist facies event that is pre-D (sub 2) . The second event, M (sub 2) , is a mid-greenschist to amphibolite facies, syn-D (sub 2) event. M (sub 3) is the last event recognized, and is a post-tectonic greenschist facies event that is regional but inhomogeneous in extent, possibly reflecting thermal aureoles around post-tectonic 1.7 to 1.8 Ga Nueltin granites. The structural geology of the area is complex with four phases of deformation recognized, two of which had a significant effect on the geometry of the deposit. All of these regional events are interpreted as Paleoproterozoic in age. Relationships between deformation fabrics and mineralization, as well as the overall geometry of the mineralized envelopes, suggest that the deposit formed during syn- to late-D (sub 2) . Superimposed on the mineralization are D (sub 4) structural elements that postdate gold mineralization. The main control on gold mineralization is replacement of magnetite by pyrrhotite and pyrite in high-strain corridors. The composition of amphiboles and chlorites associated with gold mineralization is remarkably consistent and shows no spatial or temporal variation, suggesting that it was buffered by the iron-rich nature of the host rocks. The bulk metasomatic effect on the intermediate volcanic rocks is characterized by the addition of K (sub 2) O and the loss of CaO, Na (sub 2) O, and MgO, with little variation in the total iron content. The elemental losses are likely the result of destruction of feldspars, stilpnomelane, and ferroactinolite, which are relatively common in the unmineralized rocks, and the formation of sericite, chlorite, and grunerite. Textural and timing relationships suggest that the mineralization is syn- to late-D (sub 2) , and by inference M (sub 2) . Fluid inclusions, chlorite, and arsenopyrite geothermometry all suggest that mineralization took place at about 325 degrees to 375 degrees C and 1.3 kbar pressure. These are lower P-T conditions than is indicated by M (sub 2) mineral assemblages, suggesting that the deposit formed during the waning stages of metamorphism. Strain partitioning due to the mechanical contrast of the iron formation preferentially localized dilational settings during D (sub 2) deformation. This allowed fluid influx, sulfidation of the iron formation, and resulting precipitation of gold to be concentrated in high-strain corridors. Geologic relations and geochronology collectively suggest that a Paleoproterozoic (ca. 1.8-1.9 Ga) deformation event was responsible for the introduction of gold into the Neoarchean supracrustal sequences.

A. Cooper and R. Grant over several decades of fieldwork. In addition, four third-order depositional sequences, spanning approximately 10 Myr of the Leonardian and lower Guadalupian, have been correlated by previous workers to the well-documented stratigraphic framework of the Guadalupe Mountains. The brachiopods from these sequences are particularly amenable to quantitative paleocommunity analyses for several reasons. First, collections are large, numerous, and diverse (855,047 specimens; 512 species; 142 genera; 191 localities), providing a robust statistical sample. Second, the descriptions and identifications of this material were done at a high level of taxonomic consistency. Third, extraction of the silicified fossils by acid dissolution produced bulk samples appropriate for analysis of species abundances. Ordination of brachiopod data indicates that each third-order sequence has its own distinctive suite of species even though each sequence includes a similar range of carbonate ramp habitats. This suggests that the composition of brachiopod communities changed significantly in response to drops in sea-level changes (recorded stratigraphically as sequence boundaries). In contrast, analysis of the relative species abundances from each sequence indicates a decrease in the proportion of rare taxa in each sequence through the study interval, even as the overall species richness in individual collections remains high. Loss of diversity due to environmental degradation in modern ecosystems is often due to the disappearance of species with small populations, suggesting an analogous interpretation of the Glass Mountains data through the duration of the study interval. Overall, these findings suggest that the sea level fluctuations governing the deposition of the third-order sequences influenced turnover in species composition, but that other factors determined the structure and composition of each recurrent ecological landscape.

In particular, the record of durable vs. fragile organisms may be distorted if skeletal durability affects preservation potential. This study, conducted by the PDBD taphonomy working group using the Paleobiology Database [PBDB] (http://paleodb.org), tests the effect of durability on commonness of fossils. We focused on three major groups (bivalves, gastropods, and brachiopods) and restricted analyses to two time intervals best represented in PBDB (Ordovician-Carboniferous and Jurassic-Paleogene). For each group, 150 genera with the highest number of occurrences [collection records] in the PBDB were selected (450 genera total). To minimize monographic effects, the commonness of each genus was quantified as a total number of geological formations from which that genus was reported in the database (as of 09/2003). Seven taphonomic durability indices were estimated for each genus as average values computed for multiple species: mature specimens from collections or literature sources were scored in terms of body size, shell thickness, three reinforcement structures (folds, ribs, spines), shell mineralogy, and shell organic content. Results indicate that the frequency of formation occurrences of the most common genera in the PBDB is independent of durability-related characteristics. Thin-shelled and thick-shelled genera display occurrence-frequency distributions that are virtually identical in terms of shape and central tendency; results are similar for different shell mineralogies and body size classes. This pattern persists when data are analyzed separately for the Paleozoic and Meso-Cenozoic. The latter outcome is particularly notable considering substantial changes observed over time in body size, shell thickness, and the proportion of aragonitic fauna. Because a temperate-latitude bias in Meso-Cenozoic records should act against the observed secular changes in body size, shell thickness, and mineralogy, these trends likely reflect genuine biological patterns rather than taphonomic artifacts.

Restudy of F. B. Meek's type material indicates that the small, arcuate, tapered tubes lack definitive scaphopod characters. Instead, they resemble shells built by serpulid worms (Polychaeta) of the genus Hamulus, so D. subquadratum Meek, 1860 is here transferred to Hamulus subquadratus (Meek, 1860). Fieldwork indicates that Meek's syntype slab came from the Redwater Shale Member (Oxfordian) of the Sundance Formation, 14 mi (22.5 km) southwest of Casper, Wyoming.

The samples were collected at two-week intervals using a 500 mu m mesh net with a 0.5 m diameter opening. Copepods (23-31%) and ostracods (20-34%) were predominant throughout the year, followed by cladocerans (2.5-14%), zoea (6.6-9.5%), and siphonophores (2.5-7.2%). High densities of zooplankton were obtained in February and March with peak abundance on March. The lowest densities were observed on September and November. Significant differences in abundances at each station were observed for the groups Acartia tonsa (Copepoda), Ctenophora, Medusae, Ostracoda, Zoea, and Amphipoda. Comparison of the dry and rainy seasons revealed significantly higher zooplankton abundance in the dry season and copepod domination in all stations; during the rainy season, ostracods dominated the off-shore areas. Zooplankton abundance and distribution are influenced by upwelling, which occurs during the dry season in Culebra Bay.

Two ancient Greek cities, Herakleion and Eastern Canopus, originally occupied low-lying delta coastal areas along the Canopic channel of the Nile. Both were unprotected against flooding, earthquake, tsunami, and consequent subsidence. These sites, recently discovered in Abu Qir Bay on the northwestern margin of Egypt's Nile delta, were lowered a total of 8 m during the past 2500 yr, and now lie at water depths of 5-7 m. The two cities were located along the delta coast at river mouths that flooded annually, and man-made structures were built directly on underconsolidated sediment prone to geohazards. Processes leading to their submergence are interpreted on the basis of integrated archaeological, physiographic, geological (including cores), and geophysical (side-scan sonar, nuclear resonance magnetometer, high-resolution seismic) information. Gradual subsidence due to relative sea-level rise (eustatic rise, land lowering by sediment compaction) accounted for 4-5 m of submergence. Episodic failure during floods and earthquakes by loading and sediment remobilization of the water-saturated substrate upon which the cities were situated likely caused the additional 3-4 m of subsidence. Without foundations, pilings, dikes, or other protection measures, it is not surprising that the sites, over the long term, were damaged and subsided completely into the bay. Ancient cities discussed here cause us to reflect on present-day site selection and construction practices in modern deltaic and associated wetland settings, and potential challenges related to substrate failure and other coastal hazards.

Analyses of both salivary androgens and estrogens were found to reliably monitor follicular activity. Although the temporal patterns of the two steroids were significantly correlated (r=0.62; P<0.05), they differed slightly. Salivary androgens increased earlier during the follicular phase, although both peaked at the same time in association with behavioral estrus. Based on salivary androgen profiles, the mean duration of the follicular phase was 11.4 days (ranged=7-15 days; n=17 cycles). Estrous cycle length, as measured by the time between consecutive androgen peaks, was 47.4-3.4 days (range=37-86 days). Salivary progestin measurements were effective for monitoring luteal function. The mean duration of the luteal phase was 15.5-1.5 days (range=10-23 days). In sum, assays were identified for measuring salivary steroids to assess ovarian function in Indian rhinoceroses. However, not all of the assay systems tested were effective, perhaps because of interfering matrix effects. Mate introductions in the Indian rhinoceros often require careful monitoring, and a technique for monitoring hormones in saliva could be an alternative to urine or fecal analyses for identifying estrus and timing breeding in this species. Such a technique would be particularly useful for situations in which it is difficult to collect uncontaminated urine and feces. Zoo Biol 23:501-512, 2004.

Emphasis has been placed on recently published literature. Special attention has been given to requirements for energy and protein and the unique roles of essential amino acids, essential fatty acids, calcium, phosphorus, zinc, copper, selenium, and vitamins A, C, D, and E. Information has been drawn from research with mammals, birds, reptiles, amphibians, and fish, including the domestic and laboratory species that play such a large role in elucidating mechanisms connecting nutrition and reproduction.

Thus, a survey was conducted to determine how behavior and dominance status relate to each other and to ovarian cyclicity. For both Asian and African elephants, dominance status was positively correlated with relative size, age, temperament, disciplinary nature, and willingness to share novel objects. Relative size and temperament were also related to disciplinary nature toward herdmates. Behavior toward keepers was a good indicator of the willingness of elephants to follow commands, whereas sharing novel objects was positively correlated with object curiosity. Finally, dominance status, temperament, and disciplinary nature were all correlated with willingness to share. Comparisons of ovarian cyclicity status with behavior rankings were conducted only for African elephants because of the low number of noncycling Asian elephants surveyed. Overall, social status appeared to be the best predictor of ovarian activity in African elephants. Noncycling African elephant females ranked higher in the dominance hierarchy and gave more discipline to herdmates than cycling cohorts. It remains to be determined whether these are cause or effect relationships, but clearly it is important to understand how physical and social attributes impact physiological processes, such as reproduction. Captive management now needs to focus on optimizing social and environmental conditions to maximize reproductive potential in elephants. Zoo Biol 23:431-448, 2004.

Significant increases in FA have been found for several species of plants and animals in response to various stresses, including environmental and genetic factors. In this study, we investigated the effects of elevated CO sub(2) on leaf symmetry of two oak species, Quercus geminata and Q. myrtifolia, and the responses of three species of leaf miners and one gall-making species to random variation in leaf morphology. Leaf FA decreased with an increase in CO sub(2) concentration. There were fewer asymmetric leaves and lower levels of asymmetry on leaf width and leaf area on elevated CO sub(2) compared with ambient CO sub(2). Leaf miners responded to leaf asymmetry, attacking asymmetric leaves more frequently than expected by chance alone. Differences in secondary chemistry and nitrogen (N) content between symmetric and asymmetric leaves may be responsible for these results due to lower levels of tannins and higher levels of N found on asymmetric leaves of Q. myrtifolia and Q. geminata.

Although common in the Argentine Pampas 100 years ago, it persists in only two small populations. The largest population has survived due to the rarity of roads, internal farm subdivisions, and the low cattle density. However, habitat condition for this population has changed dramatically in the last 16 years. Five Landsat images (1985, 1992, 1997, 1999, 2001), covering 4608 km, were used to quantify pampas deer habitat loss due to the replacement of natural grassland by exotic pastures and crops. Image classification showed that natural grassland cover was reduced from 84.5 to 37.8% between 1985 and 2001. The annual transformation rate increased significantly from 1.4 to 10.9%. Average paddock size was significantly reduced from 1470 to 873 ha, and the number of paddocks increased from 129 to 227. The land within this area proposed for a national park has not escaped these habitat changes. In the last 6 years the amount of replaced area within the proposed park has increased from 9.1 to 51.1% due to actions by ranchers to avoid inclusion within park boundaries. Three patches of natural grassland still remain within the pampas deer distribution, one of which is the proposed national park. The implementation of a national park is a decisive challenge for the survival of pampas deer and its habitat in Argentina.

Invasions result when species establish new, self-sustaining populations beyond their previous geographic ranges. Research shows that the detected rate of marine invasions in North America has increased exponentially, with a rapid rise over the past 60 years, resulting largely from the transfer of organisms by ships. In the past decade, growing alarm about biological invasions has lead to the implementation of prevention strategies to reduce the rise of new invasions. For now, mid-ocean ballast water exchange is the only readily available treatment for the problem but it has constraints. It is therefore imperative to move ahead quickly with new ballast water treatment approaches such as filtration, ozone treatment, ultra-violet radiation, heat, de-oxygenation and magnetic centrifugation. This article discusses the problem of biological invasions and the various treatment approaches.

We examined how three groups of golden-headed lion tamarins Leontopithecus chrysomelas in Southern Bahia, Brazil, used mature, swamp, secondary and shade cocoa (cabruca) forests. Unlike callitrichids that show affinities for degraded forest, Leontopithecus species are presumed to depend on primary or mature forests for sleeping sites in tree holes and epiphytic bromeliads for animal prey. In this study we quantified resource availability within each habitat, compared the proportion of time spent in each habitat to that based on availability, investigated preferences for sleeping site selection, and determined how golden-headed lion tamarins allocated time to foraging behaviour in different habitats. Each group preferred to range in certain habitats during the day, yet patterns were not consistent across groups. In contrast, all groups preferred to sleep in mature or cabruca forest. Golden-headed lion tamarins spent a greater proportion of time foraging and eating fruits, flowers and nectar in cabruca than in mature or secondary forests. Although the extent to which secondary and cabruca forests can completely sustain breeding groups is unresolved, we conclude that both habitats would make suitable corridors for the movement of tamarins between forest fragments, and that the large trees remaining in cabruca are important sources of food and sleeping sites. We suggest that management plans for golden-headed lion tamarins should focus on protecting areas that include access to tall forest, either as mature or cabruca, for the long-term conservation of the species.

We describe results from the first long-term investigation of wild golden-headed lion tamarins (L. chrysomelas; GHLTs). We present data about activity budgets, daily activity cycles, diet, daily path length, home range size, home range overlap, and territorial encounters for three groups of GHLTs that were studied for 1.5-2.5 years in Una Biological Reserve, Bahia State, Brazil, an area characterized by aseasonal rainfall. We compare our results to those from other studies of lion tamarins to identify factors that may influence foraging and ranging patterns in this genus. Ripe fruit, nectar, insects, and small vertebrates were the primary components of the GHLT diet, and gums were rarely eaten. Fruit comprised the majority of plant feeding bouts, and the GHLTs ate at least 79 different species of plants from 32 families. The most common foraging sites for animal prey were epiphytic bromeliads. The GHLTs defended large home ranges averaging 123 ha, but showed strong affinities for core areas, spending 50% of their time in approximately 11% of their home range. Encounters with neighboring groups averaged two encounters every 9 days, and they were always aggressive. Data about time budgets and daily activity cycles reveal that the GHLTs spent most of their time foraging for resources or traveling between foraging sites distributed throughout their home ranges. The GHLTs spent much less time consuming exudates compared to lion tamarins in more seasonal environments. Additionally, the GHLTs had much larger home ranges than golden lion tamarins (L. rosalia), and did not engage in territorial encounters as frequently as L. rosalia. GHLT ranging patterns appear to be strongly influenced by resource acquisition and, to a lesser extent, by resource defense.

Within the leaf-cutting ant genus Acromyrmex, two taxa of social parasites have been found, which are thought to occupy opposite grades of permanent social parasitism, based on their contrasting morphologies: Acromyrmex insinuator differs little in morphology from its free-living congeneric host species and produces a worker caste, and is thus thought to represent an early grade of social parasitism. At the other extreme, Pseudoatta spp. exhibit a very specialised morphology and lack a worker caste, both of which are characteristics of an evolutionarily derived grade of social parasitism. Here we present a molecular phylogeny using partial sequences of cytochrome oxidase I and II of about half of the known Acromyrmex species including two social parasites, their hosts and all congeneric species occurring sympatrically. We show that the two inquiline parasites represent two separate origins of social parasitism in the genus Acromyrmex. The early-grade social parasite A. insinuator is highly likely to be the sister species of its host Acromyrmex echinator, but the derived social parasite Pseudoatta sp. is not the sister species of its extant host Acromyrmex rugosus.

This bias is indicated by fossil ape paleoenvironments, molar morphology, dental microwear, the geographic pattern of extinctions, and extant apes' reliance on wooded settings. The ephemeral aspect of high-quality fruit has placed a premium on cognitive and social means of finding and defending food sources, and appears related to great apes' affinity since the Miocene for wooded, fruit-rich environments. These habitats have, however, undergone a severe withdrawal toward the low latitudes of Africa and Southeast Asia since the late Miocene, corresponding to a decline in the diversity of great apes beginning 9.5 million years ago. Plio-Pleistocene records imply that wooded settings of Africa and SE Asia were prone to substantial fragmentation and coalescence. Once apes were confined to equatorial settings, therefore, habitat instability heightened the spatial/temporal uncertainty of ripe-fruit sources. Prolonged learning, the assignment of attributes to distant places, mental representation, and reliance on fallback foods were all favored in this dynamic environmental context. These abilities helped sustain forest frugivory in most lineages. Fluid social grouping afforded the animals opportunities to locate ephemeral foods in continuous and fragmented forests. Fission-fusion grouping also magnified the problems of object impermanence (of individuals) and dispersion manifested by food sources in the ecological realm. Thus the spatial and temporal dynamics of fruit and wooded habitats since the Miocene are reflected in important components of great ape cognition, foraging, and sociality. In contrast to great apes, cercopithecoid monkeys have increased their plant dietary options and diversified in seasonal environments since the late Miocene. Early hominins eventually severed the habitat bias that characterized the evolution of great apes, and later expanded into diverse environments.

These data provide information on the latitudinal diversity gradient of plants during an ancient greenhouse climate with non-freezing winters at polar latitudes. Comparing pollen data from the early Paleogene with a pollen data set compiled at the same latitudes from the late Holocene (3000 years B.P. to present) reveals that the diversity gradient between middle to high latitudes was steeper than today at the same sampling intensity. The gradient is a step-like decrease of about 50% in taxonomic diversity with increasing latitude between regions. The diversity gradient is formed by the `spillover' of paratropical taxa into other regions of North America, which reflects the modern pattern of plant ranges. Taxa present in the Arctic, therefore, have great geographic ranges with endemism greatest in the paratropical biome. Paleogene diversity gradients show that decreasing diversity with increasing latitude is ancient and not dependent upon freezing temperatures.

The harsh dry season of 1998 that accompanied the 1997-98 El Nino was spanned by censuses at all three sites. The wet and intermediate plots were similar in total species richness, the dry site somewhat lower in diversity; all three sites differed substantially from each other in species composition. Forest-wide growth of large trees was higher at the wet and intermediate sites than at the dry site, but sapling growth was highest at the dry site and lowest at the intermediate site. Forest-wide growth differences were reflected by individual species, for example, saplings of species at the dry site grew faster than saplings of the same species at the intermediate site. Forest-wide mortality was lowest at the dry site and highest at the wet, and this difference was also reflected by individual species. We suggest that low mortality and growth in the drier forest was due to the longer annual dry season and higher deciduousness, and that high sapling growth at the dry site was due to greater light penetration to the forest floor. Growth rates were elevated at all three sites during 1998, possibly due to reduced cloud-cover during the El Nino. Contrary to expectation, mortality during 1998 was not elevated at wet and intermediate sites during the El Nino drought, but was at the dry site. Finally, we found that some species performed poorly at one site and declined in abundance, while having stable or increasing populations at another site, demonstrating that the communities are not at equilibrium.

All 17 deer appeared to be in good condition at the time of death. Gross necropsies were performed, serum was collected for serologic evaluation of selected infectious disease agents, and feces and ectoparasites were collected for evaluation of internal and external parasites. Serologic tests were positive for antibodies against bovine respiratory syncytial virus and four Leptospira interrogans serovars, with questionable results for epizootic hemorrhagic disease virus serotypes 1 and 2. No antibodies were detected to Anaplasma marginale, Babesia bigemina, Babesia bovis, Babesia odocoilei, bluetongue virus (serotypes 2, 10, 11, 13, and 17), bovine viral diarrhea virus, Brucella abortus, foot-and-mouth disease virus, infectious bovine rhinotracheitis virus, Mycobacterium avium subsp. paratuberculosis, and parainfluenza-3 virus. Sixty-four percent (7/11) of the deer had endoparasites. Amblyomma spp. ticks were found on seven deer, flies of the family Hippoboscidae on six deer, and lice on six deer.

Here I review the literature on the ecology of woodland herbs. The review is timely because, since Paulette Bierzychudek's seminal review of the subject in 1982, a number of species have become rare or threatened owing to the conversion of forests to other land uses, competition by alien plant species, and increased abundance of native wildlife that negatively impact woodland herbs (e.g., white-tailed deer). Although the basic biology of woodland herbs is mostly known, few species have been studied in detail, and we are only able to make broad generalities about their ecology. We are especially lacking in information needed to conserve and restore species in altered and threatened habitats.

Because enhancement efforts have focused on finfish, even less information is available with which to assess enhancement potential of crustaceans. The Chesapeake Bay stock of blue crabs Callinectes sapidus has declined by more than 80% over the past 12 years and has exhibited recruitment limitation, leading to recent efforts to study the potential of enhancing populations with hatchery-reared juveniles. To assess how hatchery- raised juvenile blue crabs may fare after release into the Chesapeake Bay, we compared several aspects of hatchery and wild crabs. Hatchery crabs readily fed on natural prey, moved in the field similarly to wild crabs, and grew at rates similar to those of wild crabs; however, the two crab groups differed in other factors important to field survival. Prerelease and laboratory- held hatchery crabs had different carapace morphology (smaller spines) than wild crabs, though spine lengths increased to normal proportions by several weeks after release. Hatchery crabs did not initially bury in sediment as often as wild crabs, suggesting inexperience with an important predator escape response. Hatchery crabs were also preyed upon at higher rates in the field than wild crabs. Conditioning experiments suggest that inexperience with sediment and low burial rates were not the main cause of higher predation. By identifying areas in which hatchery individuals may be relatively weak and deficits that can potentially be mitigated, studies such as this can lead to improving the success of hatchery- raised individuals in the field. On a broader scale, such studies also contribute to determining whether stock enhancement is possible in the case of the Chesapeake blue crab.

The channels of the Eau Morte, Ire, and Bornette rivers are almost completely channelized in their lower reaches as a result of human activity, with flow contained along parallel, but separate, paths from headlands in the proximal drainage basin directly to the lake. Petrographic data from river samples collected in this study serve to differentiate sand-size material carried by each fluvial system. Proportions of the dominant (limestone) and five additional (dolomite, quartz, gypsum, rock fragments, and 'other') components in the 3 rivers are more closely related to source supply than to fluvial transport effects or sampling strategy. Of the 7 components, mica best records the influence of depositional mechanisms. Much of the carbonate sand and coarser material at the lake shore is derived from widespread Mesozoic outcrops. Non- carbonate sand input, partially resulting from erosion of glacial till deposits and pedogenic horizons in the southern drainage basin, provides key compositional markers to differentiate between sediment carried to the lake by each river. Until several centuries ago, deposits of the Eau Morte, Ire, and Bornette flowed to the Bou du Lac, and formed a merged, multifluvial lacustrine delta. As drainage and channel containment projects related to agricultural development intensified in lake margin lowlands, the 3 channels were separated on the delta surface, allowing bypass of river material directly onto subaqueous deltas in the lake. Specific mineral assemblages, especially quartz, mica and rock fragments, may prove useful as key tracers of human- altered sediment between the margin and deeper lake sectors.

This study focuses on the Canopic's evolution at the delta margin and in Abu Qir Bay seaward of the coast. Information from historic documents, integrated with data from geographical, geological, and archaeological exploration in the bay, indicates that the Canopic distributary was active from similar to 4000 B.C. to the end of the 1st millennium A.D. Fluvial discharge persisted through pre-Dynastic, Dynastic, Greek, Roman, Byzantine and early Arabic time. The channel flowed to two sites, Herakleion and Eastern Canopus, established by the Greeks as navigational gateways for trade in the delta and surrounding region. Eastern Canopus functioned until the mid-8th century A.D. At that time, flow in the Canopic had decreased markedly, and Nile water was diverted to the east, through the Bolbitic-Rosetta branch. By the end of the first millennium A.D., Nile water was channeled in the Rosetta and Damietta distributaries, and the Canopic branch eventually converted to a canal and drain system. The Canopic promontory across which the branch flowed, and the 2 ancient sites located at the promontory coast near Canopic channel mouths, subsided beneath the waters of the bay after the 8th century. Submergence was a response to interaction of eustatic sea-level rise, annual floods, growth-faulting, soft-sediment deformation and other natural processes. As the Canopic promontory subsided, Abu Qir Bay attainted a marked concave-seaward shape and its shoreline shifted southward. This geoarchaeological investigation helps distinguish the long-term impact of natural events from that of increased human activity. This distinction is of practical importance for the highly populated and vulnerable delta margin that continues to experience submergence and erosion.

Persistence does not require lack of change or the absence of variation from one occurrence of the assemblage to the next in geological time. It does, however, imply that assemblage composition is bounded and that variation occurs within those bounds. The principal cause for these patterns appears to be species-, and perhaps clade-level, environmental fidelity that results in long-term tracking of physical conditions. Other factors that influence persistent recurrence of assemblages are historical, biogeographic effects, the "law of large numbers," niche differentiation, and biotic interactions. Much research needs to be done in this area, and greater uniformity is needed in the approaches to studying the problem. However, great potential also exists for enhanced interaction between paleoecology and neoecology in understanding spatiotemporal complexity of ecological dynamics.

The frog, uncontrolled by natural predators, has spread to most of the Islands, colonizing the moist areas found under leaves and leaf litter. Highly adaptable, the frog also reproduces at a rapid rate, resulting in a density of 6000 per acre, much higher than in its native Puerto Rico. Infested areas are characterized by the loud and high-pitched screeching that the frogs emit. The frog is also a major threat to the nursery industry.

While the Inuit of Canada and Alaska have replaced their dogs with snowmobiles, a ban on these machines in northern Greenland, coupled with a legal restriction against the importation of other dog breeds has cemented the historic relationship between humans and dogs in this culture. Dog breeders and guides use the teams to haul goods, for seal hunting trips, and for general transportation in this northernmost community. Unlike the Siberian huskies used as sled dogs in Alaska, the Inuit dogs are slower but more powerful, suited to work for long hours at extremely cold temperatures.

2013-040219 AB - Gastropods have lost the quintessential snail feature, the coiled shell, numerous times in evolution. In many cases these animals have developed a limpet morphology with a cap-shaped shell and a large foot. Limpets thrive in marginal habitats such as hydrothermal vents, the high-energy rocky intertidal areas and fresh water, but they are considered to be evolutionary dead-ends, unable to re-evolve a coiled shell and therefore unable to give rise to the diversity seen among coiled snails. The re-evolution of a coiled shell, or any complex character, is considered unlikely or impossible (Dollo's law) because the loss of the character is followed by the loss of the genetic architecture and developmental mechanisms that underlie that character. Here, we quantify the level of coiling in calyptraeids, a family of mostly uncoiled limpets, and show that coiled shells have re-evolved at least once within this family. These results are the first demonstration, to our knowledge, of the re-evolution of coiling in a gastropod, and show that the developmental features underlying coiling have not been lost during 20-100 Myr of uncoiled evolutionary history. This is the first example of the re-evolution of a complex character via a change in developmental timing (heterochrony) rather than a change in location of gene expression (heterotopy).

Here we show that this well-accepted idea requires re-examination. Island inundation during hurricanes can have devastating effects on lizard populations in the Bahamas. After severe storms, islands may be recolonized by over-water dispersal of lizards from neighbouring islands. High levels of gene flow may homogenize genes responsible for divergence, and are widely viewed as a constraining force on evolution. Ultimately, the magnitude of gene flow determines the extent to which populations diverge from one another, and whether or not they eventually form new species. We show that patterns of gene flow among island populations of Anolis lizards are best explained by prevailing ocean currents, and that over-water dispersal has evolutionary consequences. Across islands, divergence in fitness-related morphology decreases with increasing gene flow. Results suggest that over-water dispersal after hurricanes constrains adaptive diversification in Anolis lizards, and that it may have an important but previously undocumented role in this classical example of adaptive radiation.

AN - 71353998; 14607426 AB - A colorimetric method for measuring the viability of Leishmania promastigotes is described that is based on the reduction of the tetrazolium salt, XTT, to a water-soluble formazan. Values obtained by the XTT method correlated well with parasite number (r=0.965) and with methods that rely upon the reduction of MTT or MTS (r=0.96 and 0.97, respectively). The IC(50) values obtained by XTT method with amphotericin-B, miltefosine and ketoconazole were similar to those previously reported by other methods. The XTT method proved to be a reliable and convenient method for the screening of methanolic extracts from 1059 plants and was used for the bioassay-guided fractionation of the alkaloid aegeline from Sarcorhachis naranjoana.

These tunnels are rectangular in cross-section and are the largest of any yet reported in natural or synthetic Mn oxides. The thermal stability of woodruffite is comparable to that of todorokite and other large-tunnel Mn oxide phases, breaking down at approximately 300 degrees C and eventually transforming to a spinel-type structure. The woodruffite structure may serve as a model for a new class of octahedral molecular sieves with enhanced capabilities as catalysts and selective cation-exchange agents.

Physical and biological taphonomic attributes measured from coral specimens showed great variability with respect to reef environment. Physico-chemical degradation (abrasion and dissolution) was greatest in reef-crest and patch-reef environments. With the exception of encrusting foraminifera, coverage by epi- and endobionts was higher in deep-reef environments (20 m and 30 m). Variability in dissolution and abrasion is likely the result of the different energy regimes present in the reef habitats examined. Variability in biological attributes results from a combination of increased residence time of coral skeletons on substrates in deep-reef environments, higher overall coral skeletal densities of corals inhabiting deep reef environments, and increased nutrient availability in the deep reefs sampled. Clear gradients in the degree of taphonomic alteration of reef corals with reef habitat indicate the utility of corals as taphofacies indicators in ancient reef settings. In contrast to shallow-water reefs on the Great Barrier Reef, taphonomic alteration of corals in the Florida Keys was equitable across growth forms.

The fossil was determined to come from the Middle Miocene (14 Ma) Pungo River Formation based on sedimentary, preservational, and other lines of evidence. This in turn implies that Heliornis did not spread into South America until after the isthmian land connection about 3 Ma and that the interchange of Heliornithidae between the Old and New World probably took place through the Northern Hemisphere in the Paleogene.

A wide variety of lithological and palaeontological features characterize this sequence comprising unfossiliferous and fossil-bearing sand- and siltstones, and diverse rudist and coral-rudist associations in carbonate or mixed carbonate/clastic lithologies. A total of 24 rudist and coral-rudist associations are exposed in the investigated section, which are grouped into 5 limestone units. Radiolitid assemblages, coral-rudist reefs, coral-dominated reefs, and hippuritid-dominated reefs are present. The stacking pattern of these reef intervals indicates a general transgressive trend through the entire section. Smaller-scale facies trends could be distinguished within each limestone unit, comprising deepening-upward sequences, defined by a shoreface-calcareous algae-radiolitid-marl facies transition, and shallowing-upward sequences defined by a hippuritid-actaeoneilid-coral/rudist facies transition. This cyclic sedimentation pattern is obscured by an episodic input of clastic sediments derived from the uplifting Sierra Madre Oriental, which in turn triggered either the development or decline of reefs.

Nonetheless, widespread access to predictions of subsurface contributions to rivers, lakes, and wetlands at a scale useful to environmental managers is generally lacking. In this paper, we describe a 'neighborhood analysis" approach for estimating topographic constraints on spatial patterns of recharge and discharge and discuss how this index has proven useful in research, management, and conservation contexts. The Michigan Rivers Inventory subsurface flux model (MRI-DARCY) used digital elevation and hydraulic conductivity inferred from mapped surficial geology to estimate spatial patterns of hydraulic potential. Model predictions were calculated in units of specific discharge (meters per day) for a 30-m super(2)-cell raster map and interpreted as an index of potential subsurface water flux (shallow groundwater and event through-flow). The model was evaluated by comparison with measurements of groundwater-related attributes at watershed, stream segment, and local spatial scales throughout Lower Michigan (USA). Map-based predictions using MRI-DARCY accounted for 85% of the observed variation in base flow from 128 USGS gauges, 69% of the observed variation in discharge accrual from 48 river segments, and 29% of the residual variation in local groundwater flux from 33 locations as measured by hyporheic temperature profiles after factoring out the effects of climate. Although it does not incorporate any information about the actual water table surface, by quantifying spatial variation of key constraints on groundwater-related attributes, the model provides strata for more intensive study, as well as a useful spatial tool for regional and local conservation planning, fisheries management, wetland characterization, and stream assessment.

This community structure was indistinguishable from that of a typical native host. In contrast, the P. umbellatum assemblage was unusual as no species represented >10% of individuals.The aggressive invasion by P. aduncum of early successional vegetation is not explained by a competitive advantage due to low herbivore load, as the abundance of caterpillars feeding on it was comparable to that of native pioneer plants.The caterpillar assemblage on P. aduncum demonstrated that an assemblage indistinguishable from native assemblages in density, species richness, and dominance structure (but not in host specificity) can originate from the existing species pool in lowland rainforests on a recently established tree species in <50 years.

This hypothesis was evaluated for the 73 most abundant canopy tree species from Barro Colorado Island, Panama. The percentage of recruits located in tree-fall gaps (P), sapling growth (G), and mortality (M) rates, and the coefficient of skewness of size distributions (g sub(1)) were determined from censuses of all individuals >10 mm dbh in a 50-ha plot. Seven qualitative, bivariate predictions relating g sub(1), G, M, P, and wood density (W) were evaluated. Six of the seven predictions were substantiated in pairwise analyses. A path analysis integrated all seven predictions and explained 51% of the interspecific variation in g sub(1). Size distributions with many large individuals and a long tail of relatively rare, small individuals (g sub(1) 0) characterized shade-tolerant species with the opposite traits. The percentage of tropical tree species that require tree-fall gaps to regenerate has been estimated to range from 70% for old-growth forests. Our analyses suggest that there are not large numbers of functionally equivalent species at either extreme of the regeneration continuum. Rather, there are very few extremely shade-tolerant and extremely light-demanding species. Most species have intermediate light requirements and lifestyles.

The measurements were made in open-top chambers (OTCs) modified to function as open gas-exchange systems. The OTCs enclosed samples of the ecosystem (ca. 10 m super(2) surface area) that had regenerated after a fire, 5 years before, in either current ambient or elevated C sub(a). Throughout the study, elevated C sub(a) increased maximum NEE (NEE sub(max)) and the apparent quantum yield of the NEE (H sub(NEE)) during the photoperiod. The magnitude of the stimulation of NEE sub(max), expressed per unit ground area, was seasonal, rising from 50% in the winter to 180% in the summer. The key to this stimulation was effects of elevated C sub(a), and their interaction with the seasonal changes in the environment, on ecosystem leaf area index, photosynthesis and respiration. The separation of these factors was difficult. When expressed per unit leaf area the stimulation of the NEE sub(max) ranged from 7% to 60%, with the increase being dependent on increasing soil water content (W sub(soil)). At night, the CO sub(2) effluxes from the ecosystem (NEE sub(night)) were on an average 39% higher in elevated C sub(a). However, the increase varied between 6% and 64%, and had no clear seasonality. The partitioning of NEE sub(night) into its belowground (R sub(below)) and aboveground (R sub(above)) components was carried out in the winter only. A 35% and 27% stimulation of NEE sub(night) in December 1999 and 2000, respectively, was largely due to a 26% and 28% stimulation of R sub(below) in the respective periods, because R sub(below) constituted ca. 87% of NEE sub(night). The 37% and 42% stimulation of R sub(above) in December 1999 and 2000, respectively, was less than the 65% and 80% stimulation of the aboveground biomass by elevated C sub(a) at these times. An increase in the relative amount of the aboveground biomass in woody tissue, combined with a decrease in the specific rate of stem respiration of the dominant species Quercus myrtifolia in elevated C sub(a), was responsible for this effect. Throughout this study, elevated C sub(a) had a greater effect on carbon uptake than on carbon loss, in terms of both the absolute flux and relative stimulation. Consequently, for this scrub-oak ecosystem carbon sequestration was greater in the elevated C sub(a) during this 2-year study period.

Population dynamics and gene flow are of major interest in this species because they influence speciation processes and microevolution, and could consequently provide a deeper understanding of the evolutionary processes involved in mate recognition. Although earlier studies have documented genetic variation across the species' range, attempts to investigate dispersal on a local level have been limited to mark-recapture studies. These behavioural studies indicated high mobility at a scale of several hundred metres. In this study we used seven highly polymorphic microsatellite loci to investigate fine-scaled genetic variation in the tungara frog. We analysed the influence of geographical distance on observed genetic patterns, examined the influence of a river on gene flow, and tested for sex-biased dispersal. Data for 668 individuals from 17 populations ranging in distance from 0.26 to 11.8 km revealed significant levels of genetic differentiation among populations. Genetic differentiation was significantly correlated with geographic distance. A river acted as an efficient barrier to gene flow. Several tests of sex-biased dispersal were conducted. Most of them showed no difference between the sexes, but variance of Assignment Indices exhibited a statistically significant male bias in dispersal.

Using batch and 'semi-continuous' laboratory cultures, we examined in more detail the nutrient conditions that trigger feeding in C. furca. Cultures were maintained at a range of nitrogen (N) and phosphorus (P) concentrations for 31 to 36 d. Several parameters were determined at regular intervals, including inorganic nutrient concentrations of the medium, C. furca abundance and size, cellular chlorophyll a (chl a), C, N, and P contents and densities, photosynthetic rates, and ingestion of ciliate prey. We detected significant differences between treatments in all cellular parameters measured. Most notably, feeding only occurred in cultures that had been growing under N- or P-deplete conditions for 11 to 16 d, whereas nutrient-replete cells did not ingest prey. Feeding increased markedly as cellular C:N:P ratios deviated farther from those found under optimum growth conditions. Specifically, feeding in P-deplete cultures increased at C:P ratios >130 and at N:P ratios >19, whereas N deplete cultures required a C:N ratio of similar to 10 and an N:P ratio <7 to commence feeding. Growth and photosynthetic rates were reduced compared to those of nutrient-replete cells regardless of the limiting nutrient. In N-limited cultures, cell size and chl a density decreased compared to nutrient-replete cells, whereas the size of P-limited cells significantly increased. This change in average cell size was caused by the development of a bimodal size distribution under N- and P-reduced conditions, raising the possibility of sexual reproduction in C. furca. Changes in cellular parameters were reversible upon nutrient addition, and feeding decreased or ceased within hours to days. The findings presented here indicate that cellular nutrient quotas and ratios are more critical than absolute inorganic nutrient concentrations in regulating feeding behavior of C. furca.

AN - 71283866; 12890738 AB - Teratospermia (>60% of morphologically abnormal spermatozoa) is well documented in felids. Even morphologically normal spermatozoa from teratospermic ejaculates have reduced ability to undergo tyrosine phosphorylation, acrosome react, and bind and penetrate oocytes compared with normospermic ( 0.05) proportions of oocytes fertilized after ICSI using spermatozoa from normo- and teratospermic cats.

The process of determining the availability or even the existence of Earth history data remains a time-consuming and error-prone enterprise because there are no centralized depositories or Web-enabled means for locating and retrieving data. Our goal is to deliver a dynamic, interactive and time-calibrated framework for Earth system history as a network of comprehensive databases containing information related to the evolution and diversity of life, climate change, geochemical cycles, geodynamical processes, and other aspects of the Earth system. We call this network the CHRONOS system (www.chronos.org, where a complete list of project participants is available). With a "central hub" coordinating a continually expanding network of individual databases linked by geologic time, the community-based CHRONOS system will serve as a major portal for geological research and outreach, equipped with powerful, interactive analytical and visualization toolkits to enable the exploration and understanding of our evolving planet. With the wealth of existing Earth history data that can be integrated with state-of-the-art information technologies and advanced correlation tools, we also anticipate that the implementation of CHRONOS will result in an order of magnitude increase in the precision of global and regional geological time scales. This alone represents a major advance in Earth system history research, and is expected to lead to new insights into the rates and magnitudes of important geological processes, many of which are relevant to understanding Earth system changes influenced by human activity. Beyond addressing scientific issues, CHRONOS will also provide broad educational and societal benefits with contributions of readily accessible information on topics of general interest (e.g., evolution, extinctions), by supporting a large number of graduate and undergraduate students, and by facilitating studies of issues of immediate concern (e.g., global warming, climate change).

However, interest in this approach faded because of a lack of precision that precluded meaningful principles from emerging about the possible evolution of food-web structure. Since the early 1990's, ecologists have addressed contemporary food webs with increasing rigor by using more sophisticated data collection, analysis, and modeling techniques. It is now possible to quantify complex food-web network structure, the effects of resolution and sampling effort on structure, and the relationship of structure to ecosystem function, dynamics, and stability. These advances, in turn, provide a new conceptual basis for constructing and analyzing food webs based on fossil data. We have compiled detailed food webs for the marine Middle Cambrian Burgess Shale in British Columbia (505 Ma), the marine Late Carboniferous Ames Limestone and Shale in Ohio (320 Ma), and the earliest Middle Eocene Messel Shale in Germany (49 Ma), which encompasses both terrestrial and freshwater species. These food webs comprise 154, 203, and 367 taxa, respectively. Taxa that share the same set of predators and prey are aggregated into "trophic species," resulting in "trophic webs" with 53, 41, and 346 functionally distinct taxa. For each trophic web, the "connectance," which specifies the proportion of possible links that are actually realized (links per species 2 = 0.04, 0.10, and 0.01), as well as other parameters, are within or near ranges observed for modern food webs. Average trophic levels of the webs are 2.0, 2.7, and 2.1 and maximum trophic levels observed for a taxon in each web are 3.0, 5.6, and 5.0. Despite the very different temporal, spatial, and ecological contexts of these three paleo-food webs, there appear to be no intractable problems in reconstructing complex webs for carefully chosen and well-documented fossil assemblages. Analyses using these and other data sets will enable us to test the generality of current food-web theory and assess whether and how food-web structure and function shifts. Thus, our investigation points to new opportunities for robust, quantitative analysis of the evolution of ecosystem structure through the Phanerozoic.

Previous work has suggested dramatic increases in the alpha diversity of terrestrial plants during the Devonian-Carboniferous interval (concurrent with the radiation of several pteridophyte groups and the earliest seed plants) and Cretaceous-Paleogene interval (concurrent with the radiation of angiosperms). However, direct comparison of alpha diversities estimated from fossil assemblages can result in deeply flawed interpretations if taphonomic biases and sampling issues are not considered. Here we analyze species lists drawn from over 6000 fossil plant localities compiled in the Paleobiology Database (www.paleodb.org) from primary literature, museum collections and personal field work and vetted by specialists. Analyses were restricted to North American and European macrofloras preserved in non-marine fluvial, deltaic, and lacustrine environments where specimens were collected from geographically well-constrained (e.g., <10X10 m) and stratigraphically well-constrained (e.g., a bed or horizon) sites. The paleolatitude of each site was derived from modern coordinates and estimated plate rotations. The number of species and morphospecies was tabulated for each collection and, because the paleobotanical record mainly consists of isolated organs, several approaches to estimating alpha diversity are compared. Our results indicate that standardization of the number of localities per unit time is critical. While the range of diversities increased during the two intervals (driven by an increase in the maximum in both instances), the pattern is much more complicated when mean, sampling-standardized, alpha diversity is considered. Preliminary results indicate that the intervals of increasing mean alpha diversity were not driven by greater sampling of low-paleolatitude floras, perhaps because the locus of peak diversity shifts from equatorial to mid-latitudes as climate shifts from ice-house to green-house intervals. Additional work will explore if latitudinal diversity gradients varied over geologic time.

However, recent experimental and field-based studies on dacites and rhyolites have shown this method produces systematic errors in T and fO under more oxidizing conditions using current models. We have analyzed oxides from several experiments of Luhr (1990) to evaluate the effects of fO on oxide composition in samples with andesite bulk composition. El Chichon trachyandesite doped with anhydrite was equilibrated under vapor saturated conditions at 850 degrees C and 2 kbar. Charge 139 was equilibrated at fO of magnetite-hematite (MTH) and charge 165 at manganosite-hausmanite (MNH). Both charges contain large, euhedral ilmenite as phenocrysts and smaller, euhedral magnetite as groundmass grains and inclusions in plagioclase and clinopyroxene phenocrysts. The ilmenite is (Fe (super 2+) (sub 0.17) Mg (sub 0.06) Mn (sub 0.01) Fe (super 3+) (sub 1.50) Ti (sub 0.24) )O (sub 3) and the magnetite is (Fe (super 2+) (sub 0.70) Mg (sub 0.24) Mn (sub 0.07) Fe (super 3+) (sub 1.84) Al (sub 0.11) Ti (sub 0.02) )O (sub 4) in charge 139. In charge 165 the ilmenite is (Fe (super 2+) (sub 0.25) Mg (sub 0.06) Mn (sub 0.01) Fe (super 3+) (sub 1.30) Ti (sub 0.33) )O (sub 3) and the magnetite is (Fe (super 2+) (sub 0.82) Mg (sub 0.20) Mn (sub 0.06) Fe (super 3+) (sub 1.73) Al (sub 0.12) Ti (sub 0.08) )O (sub 4) . All the phenocrysts are chemically homogeneous, suggesting a close approach to equilibrium during the experiments. Temperature and fO were calculated for each of the charges using the mixing models of QUILF (Andersen et al., 1991) and MELTS (Ghiorso & Sack, 1991). For charges 139 and 165, the QUILF model gives 173 degrees and 668 degrees C, compared with 907 degrees and 1215 degrees C respectively for the MELTS model. At 850 degrees C QUILF produces Delta logfO of MTH -1.1 and MNH +0.2, whereas MELTS yields Delta logfO of MTH -1.6 and MNH -0.2 for experiments conducted on those buffers. The thermometry is rather uncertain due to the acute intersection angle of the isopleths and probably the effect of errors in the mixing models. The fO (sub 2) calculations for the MNH runs are more accurate than similar calculations in more felsic systems and are within predicted errors. This suggests that two oxides can be used for fO (sub 2) calculation up to MNH in andesites provided there is an independent estimate of temperature. The fO calculations for the more oxidized MTH runs have unacceptably large and systematic errors, indicating that those systems need modification.

Of particular interest have been Mn-oxide catalysts with large tunnel structures; they exhibit a range of tunnel shapes and sizes that offer potential for complementary catalytic or cation-exchange applications. We used synchrotron powder X-ray diffraction to study structural changes with increasing pressure for three tunnel Mn oxide minerals. Experiments were performed using a Diamond Anvil Cell (DAC) at beamline X7A at the National Synchrotron Light Source, Brookhaven National Laboratory. Powdered samples of hollandite [(Ba (sub .75) ,Pb (sub .16) Na (sub .10) K (sub .04) )(Mn,Fe) (sub 8) O (sub 16) ], romanechite (Ba (sub .66) Mn (sub 5) O (sub 10) . 1.34H (sub 2) O), and todorokite [(Mg (sub .45) ,Na (sub .42) ,Ca (sub .15) )Mn (sub 6) O (sub 12) . 4H (sub 2) O] were, in turn, loaded into the DAC at ambient pressure and room temperature along with a few small ruby chips. A mixture of methanol:ethanol:water was used as a pressure transmitting fluid. The pressure at the sample was measured using the shift in the R1 emission line of the included ruby chips. Data were collected with a gas-proportional position-sensitive detector and radiation wavelength of 0.6839(1) Aa. Powder X-ray diffraction data were measured at pressure increments of 0.5-1.0 GPa between ambient pressure and 7 GPa; the samples were equilibrated for about 15 minutes or more at each measured pressure. A second set of measurements was made for each sample as the pressure was released. Unit-cell parameters were determined by whole pattern fitting using the LeBail method. The hollandite structure (I2/m) has tunnels with square cross-sections measuring 2 octahedra on an edge (2 X 2), and as pressure increased to approximately 3 GPa, the a-axis lengthened, b and c and unit-cell volume decreased, and beta increased. Above approximately 3 GPa, a started to decrease, and the slopes of the changes for the other parameters changed, suggesting a phase transition at about 3 GPa. Romanechite (C2/m) has 2 X 3 tunnels, and with increasing pressure all axial parameters and volume decreased and beta increased, exhibiting a slight change in slope at approximately 2 GPa. For the todorokite structure (P2/m), with 3 X 3 tunnels, the c-axis increased slightly below 1 GPa, but at higher pressures all of the axial parameters and unit-cell volume decreased and beta increased, consistent with a steady collapse of the tunnels.

Early middle Eocene (Lutetian) amber from the Mississippi Embayment of Arkansas (USA) is quite brittle and fragile. Greatly improved imaging of this material has been accomplished by hardening the amber in an artificial resin (Epo-Tek, Epoxy Technology, Billerica, MA). This process, which imparts rigidity to the amber, greatly increases its translucency and allows for sectioning by sealing most cracks through the embedding of individual pieces. The artificial resin is prepared by carefully mixing four parts of epoxy to one part hardener (by weight). This mixture is poured over individual samples contained in clear plastic boxes. Because of the lower density of both amber and its inclusions, such as bark, with respect to the density of the artificial resin, pieces first must be firmly glued inside the boxes with a drop of artificial resin before they are filled completely. No more than 25 ml of the artificial resin should be prepared in a container, as the exothermic mixture will begin to heat faster if prepared in larger quantities. Soon after the amber specimens are covered with the artificial resin, air bubbles contained within the amber are removed in a vacuum chamber pumped to 30 torr, and the specimen is slowly dried at room temperature. The artificial resin-coated inclusions are studied with a photomicroscope equipped with an electronic image processing package, such as Auto-Montage (Syncroscopy, Frederick, MD). Out of the 338 pieces studied thus far, seven (2.1%) have arthropod inclusions (including a mite, a heteropteran, a roach, a mosquito, and a beetle) and six (1.8%) have plant inclusions (including petals and possibly moss foliage). Most pieces (93.6%) have tree bark inclusions, strongly suggesting that these amber samples represent an outer layer of resin intercalated between wood and bark. As a result of this preliminary study, a comparison with amber deposited in another major collection currently is being undertaken.

It is, then, perhaps ironic that the founder of historical geology, Nicolaus Steno (1638-1686), spent the last years of his life as a theologically conservative priest. Given the Church's harsh treatment of Galileo a few years earlier, it has often been assumed that on joining the Church Steno repudiated his geological theories or was at least under pressure to do so. There is no evidence to support this, however. In fact, Steno published his most important geological work after converting to Catholicism, and his ultra-orthodox patron, Cosimo II d'Medici, enthusiastically supported his geological studies. To make sense of this apparent paradox, it is important to view Steno's work within the religious and scientific climate of the time. Conservative as it was, the Catholic Church was generally more open to allegorical interpretations of the Bible than were its Protestant counterparts. In fact, the differing approaches to interpreting Scripture between Protestants and Catholics were among the reasons cited by Steno for converting to Catholicism. Also, preserving the Biblical chronology of Ussher and others was less important to many orthodox Christians than was thwarting the heresy of an eternal or cyclical world, which implicitly denied the existence of a Creator. The unidirectional earth history implied by Steno's study of Tuscan strata may therefore have been seen as a bulwark against eternalism rather than a threat to Biblical literalism. Though Steno tried to harmonize geological history with Genesis, and though he certainly had no concept of the true scope of geological time, the mechanisms he proposed for the rise and fall of sea level imply that he was open to the possibility of an earth history longer than six thousand years. In 1988, Pope John Paul II beatified Steno, citing him as a symbol of appropriate respect and harmony between science and faith. Acknowledging the complexity of the past relationship between science and religion may help dispel the stereotypes that can mar modern-day debates.

Mn oxides readily participate in cation-exchange and oxidation-reduction reactions, and because they typically form as coatings and fine-grained aggregates with large surface areas, even small quantities can significantly affect the chemical composition and behavior of sediments and associated aqueous systems. Additionally, because of their great chemical activity, synthetic birnessite-like phases are being extensively studied as possible catalysts, cation-exchange agents and battery materials. Of critical importance to the possible usage of birnessite as a cathodic material in solid-state batteries is its capacity to incorporate H ions during battery discharge. In this study, we examined the exchange of H for Na in birnessite in real time through synchrotron X-ray diffraction. Na-birnessite powders were exposed to HCl solutions (pH 3) at room temperature in a quartz capillary flow-through cell for approximately 1 hr, by which time H exchange was complete. Data were collected with an imaging plate, which allowed full-pattern diffraction patterns to be obtained every 2 minutes. Rietveld analyses of these time-resolved diffraction experiments confirm the proposition that endmember hexagonal H-birnessite appears and grows concomitant with the replacement of Na by H in the triclinic starting material (Drits et al. 1997). Hexagonal H-birnessite first was observed after 20 minutes of solution flow and increased in abundance (as revealed by refined weight fractions) linearly with time at the expense of the triclinic birnessite, which was not discernible after 60 minutes. Substitution of H into triclinic Na-birnessite was manifested by systematic decreases in the a, b, c, and beta lattice values beginning 10 minutes after fluid flow was initiated, contributing to a volume decrease of approximately 1%. Refined occupancies of the octahedral Mn in the hexagonal H-birnessite suggest that some Mn cations occupy the interlayer.

Seed size is related to reproductive strategy, dispersal, growth form and phylogeny. The seed size distribution of species within a flora is correlated with climate and community type. Several studies have suggested that within-flora seed size distributions have changed over geologic time, but it is not clear how well fossil seed assemblages reflect the original vegetation. Taphonomic filters such as transport, predation, biodegradation and abundance may affect the fidelity of fossil seed assemblages. Seeds may be selectively destroyed or transported on the basis of size, thus causing the distribution of a fossil assemblage to differ from that of the source community. To assess the effects of these taphonomic filters, a live-dead study was performed in which the seed size distributions of a potential fossil assemblage and the living plant community that it represents were compared. 20 six-inch diameter soft-sediment cores were collected in two transects parallel to the shore in a tidal estuary in Edgewater, Maryland. The transects grade from pebbly clay to silt to organic-rich mud. The sediment cores were sieved and the seeds assigned to 44 taxa (potential fossil or death assemblage). 40 seed plant species were identified on the adjacent hillside (life assemblage). Seed mass was determined from herbarium specimens and literature. Although species of different growth forms and dispersal mechanisms had significantly different distributions, results indicate that the differential production and dispersal of seeds in these categories does not appear to have had significant effects on the death assemblage distribution. A composite taxon list was drawn from all cores, and the resulting combined death assemblage was not significantly different from the life assemblage (P = 0.1259). This case study indicates that fossil seed size distributions can be reliable indicators of an important paleoecological variable of the original source vegetation when a reasonable sample size is considered, although similar tests must be considered for other depositional settings.

This neutral model provides a basis for inferring ecological processes that govern species abundance distributions. Application of this theory to fossil brachiopod collections from the Glass Mountains (Texas; Permian) indicates significant changes in the structure of these ancient communities over a approximately 10 Myr study interval. These collections are particularly suitable for analysis of species abundances for several reasons. First, collections are large, numerous, and diverse (855,047 specimens of 512 species and 142 genera from 191 localities), providing a robust statistical sample. Second, the descriptions and identifications of this material were made by G. Arthur Cooper and Richard Grant, providing a high level of taxonomic consistency. Third, extraction of pervasively silicified fossils by acid dissolution of carbonate matrix produced bulk samples appropriate for abundance analysis. Each of the four third-order, depositional sequences recognized in the study interval has a distinctive brachiopod assemblage. Treating each sequence as a temporally distinct ecological landscape, the neutral model appears to be able to account for observed brachiopod abundance distributions. In addition, significant differences in the abundance distributions of brachiopods from the four sequences suggest that metacommunity dynamics remained consistent within sequences while differing among them. Although the assumptions of the neutral model are overly simple, it appears to provide a useful null for interpreting changes in paleoecological community dynamics through evolutionary time.

The brachiopods were thoroughly and consistently described by G. Arthur Cooper and Richard Grant, yet they have not been studied paleoecologically, nor have they been studied in the context of the available sequence stratigraphic framework. We have analyzed the distributions of 731 brachiopod species within the Glass Mountains in the southern part of the basin (264 Wolfcampian; 172 Leonardian; 312 Guadalupian). Despite claims that the brachiopods were over-split taxonomically, the number of single occurrences is not statistically different from modern benthic foraminifera or from late Cretaceous mollusks. The Chao2 estimator of total species richness suggests that 87% of all Wolfcampian species were sampled, but only 64% of the Leonardian and 61% of the Guadalupian. None of the analyses suggest that sampling, silicification, or taxonomic analysis has biased the overall fauna to preclude paleoecological analysis. Rarefaction based on the number of occurrences of genera confirms that high-diversity assemblages occurred throughout the study interval, and in both the Glass and Guadalupe Mountains. However, the species-level rarefactions based on occurrences reveal that 4 of the 5 most diverse assemblages are from the Glass Mountains suggesting the presence of a species richness gradient in the brachiopod faunas of the Delaware Basin. A subset of 191 localities (including 512 species and 142 genera) from the Leonardian and lower Guadalupian of the Glass Mountains samples four third-order depositional sequences. Ordination of these brachiopod data indicates that each third-order sequence has a distinctive suite of brachiopod species even though a similar range of carbonate ramp habitats was sampled. Overall, these data and similar analyses of other taxonomic groups provide an exceptional opportunity to reconstruct the paleoecology of a complex marine ecological landscape and how it changed over evolutionary timescales.

Coast Ranges east of Ukiah, near the boundary between the Franciscan terrain and the Great Valley Group homocline. One slice is a complex klippe comprising Snow Mtn. and nearby St. John Mtn; the other forms a synformal sheet just to the SE, near the small town of Stonyford. Early studies focused on one or the other of these volcanic masses, and tended to regard them as part of a single large thrust sheet. However, geochemical and metamorphic mineralogy data demonstrate that they are distinct and represent two seamounts, possibly the remnants of a chain. The Snow Mountain/St. John Mountain sequence consists exclusively of titaniferous, light-rare-earth-element-(LREE) enriched basalts and rare silicic differentiates (including comendites). All the rocks are highly altered greenstones; calcic pyroxene and chromite are the chief relict phases. High P/T metamorphic minerals, including lawsonite, crossite, aragonite, and near-end-member jadeite (from analcime), are ubiquitous but weakly developed. The Stonyford sequence is more diverse and includes light-REE depleted tholeites as well as titaniferous light-REE enriched alkalic basalts; extreme differentiates have not been found. Although altered, many Stonyford rocks are unexpectedly well preserved: even primary calcic plagioclase is widespread. No "blueschist" mineralogy has been found; pumpellyite and prehnite are common. Moreover, these rocks underlie Great Valley Group sedimentary rocks and are arguably now part of the Coast Range ophiolite. Although separated by only approximately 1.5 km lateral distance, the two sequences clearly do not represent a single large complex. Yet their geographic proximity can hardly be coincidental. We interpret them to be two separate seamounts or abyssal hills, likely members of a chain. One, the Snow Mountain seamount, was subducted. The Stonyford seamount somehow escaped that fate and was accreted directly to the Coast Range forearc.

Student interviews were concluded in mid to late spring, after students had completed a significant proportion of their college introductory geoscience course. Students were asked to make drawings of the global hydrologic cycle, beginning with the water cycle. Data obtained from both drawings and interviews indicated that students hold a number of misconceptions about Earth's hydrologic system. Cognitive levels progressed from simple views such as an incomplete water cycle to complex views of the hydrologic system (e.g. how water is stored and moved throughout Earth's system). Knowledge of such specific misconceptions has implications for teaching introductory geoscience courses which incorporate similar conceptually complex topics, such as the carbon cycle. Recommendations are suggested about how the use of drawing in introductory geology classrooms may also lead to the subsequent development of better pedagogical practices that promote conceptual change.

These data provide information on the latitudinal diversity gradient of plants during an ancient greenhouse climate with non-freezing winters at polar latitudes. Comparing pollen data from the early Paleogene with a pollen dataset compiled at the same latitudes from the late Holocene (3000 years BP to present) reveals that the diversity gradient between middle to high latitudes was steeper than today at the same sampling intensities. If 69 late Paleocene-early Eocene samples are taken from each region, the gradient manifests as a step-like decrease of c. 50% in taxonomic diversity from the U.S. Gulf Coast (n = 188 taxa) to the western interior (n = 90) and again a c. 50% decrease in taxonomic diversity from the western interior to the Canadian Arctic (n = 44). The diversity gradient is formed by the "spillover" of paratropical taxa into other regions of North America, which reflects also the modern pattern of plant ranges. Taxa inhabiting the Arctic therefore had great geographic ranges with endemism greatest in the paratropical biome. Paleogene diversity gradients show that decreasing diversity with increasing latitude is ancient and not dependent on freezing temperatures.

Paleogene fossil floras from middle latitudes of Patagonia are invaluable and mostly overlooked resources for bypassing this problem. These assemblages, which are well-exposed in modern desert outcrops, represent humid subtropical vegetation from the southern reaches of the expanded Neotropical forests that existed during the globally warm early Paleogene. From recent quantitative, stratigraphically and geochronologically controlled work at Laguna del Hunco, a site with early Eocene (52 Ma) caldera-lake deposits in Chubut Province, Argentina, we have recovered more than 155 leaf species from fewer than 5,000 specimens and more than 200 total morphotypes of leaves, fruits, seeds, and flowers. Fewer than 25% of these entities were previously known. This significantly exceeds the richness of Eocene floras from any other region when adjusted for sample size, yet the potential exists for many more species to be found. Laguna del Hunco features outstanding, detailed preservation equal to the most famous North American Eocene floras such as Florissant, Green River, and Republic. Preliminary work also indicates the highest diversity of well-preserved insect damage of any Cenozoic flora known, including unusually diverse and previously unrecorded examples of specialized endophytic damage such as galls and mines. The Eocene Rio Pichileufu flora, from approximately 160 km NW of Laguna del Hunco, features similar floral diversity as well as diverse insect damage. These results support the hypothesis that Neotropical hyperdiversity, usually attributed to Neogene or Pleistocene events, may have a considerably more ancient history than previously thought.

Coincident with the IETM is a worldwide decrease ( approximately 4%) in the delta (super 13) C compositions of marine and terrestrial inorganic carbon. The dissociation of methane hydrate is currently the favored mechanism for the carbon isotope excursion (CIE). Recognition of the CIE enables global correlation, constituting a powerful tool for studying the roles of differing carbon reservoirs in reducing greenhouse gas levels and curbing IETM warmth. The Williston Basin in North Dakota provides an exceptional opportunity to study terrestrial carbon cycling. We report mounting evidence that provisionally places the P/E boundary (= IETM) at the basal contact of the Golden Valley Fm., between the Bear Den Mbr. and the underlying Fort Union Fm. Inspection of palynofloras shows a succession of biostratigraphic FADs within the upper Bear Den Mbr. that are similar to those immediately post-dating the onset of the CIE in other Laramide Basin IETM records. A bulk delta (super 13) C (sub org) record spanning a lignite at the Fort Union Fm.-Bear Den Mbr. contact exhibits patterns of isotopic variation comparable to those from other terrestrial IETM delta (super 13) C (sub org) records in Western Europe. The Williston Basin bulk delta (super 13) C (sub org) record shows an initial 4% increase followed by a sharp 5% decrease from -21% to -26%. The resemblance of our delta (super 13) C (sub org) data to those from distant locales may indicate that these deposits record the global CIE at the P/E boundary. Alternatively, the isotopic pattern of variation seen in the Williston Basin delta (super 13) C (sub org) record may be an artifact stemming from the thermal alteration of preserved plant material. Further study will help refine our interpretations. Kaolinite becomes the dominant clay mineral in the Bear Den Mbr. approximately 4.5 meters above the negative delta (super 13) C (sub org) shift. The influx of detrital kaolinite likely reflects intensified chemical weathering of continental rocks under elevated pCO (sub 2) conditions, though a shift in spatial patterns of regional weathering cannot be ruled out at this point. Deposition of large quantities of kaolinite in the Williston Basin is consistent with an emerging picture indicating that enhanced chemical weathering played an important role in the cessation of the transient IETM.

Here we test the hypothesis that if global climate change plays a major role in influencing the evolution of terrestrial communities, then similar or parallel pattern of faunal change may be recorded in different parts of the world. We focus on the late Neogene, a time of major climatic and environmental variation registered in marine records. The main faunal variables under consideration are diversity, turnover, and relative taxonomic abundance. The South American data derive from the Pampean region of Argentina, with a well-known and rich record of mammalian evolution. The African data derive from the newly built Turkana Basin Paleontology Database, which includes records from several geological formations that span the late Miocene to Pleistocene of northern Kenya and southern Ethiopia. Our results indicate that late Neogene Turkana Basin mammalian diversity fluctuated in cycles of approximately 1 million years. There were several episodes of high faunal turnover, especially at around 3.5, 2.7, 2.3, and 1.9 million years ago (Ma). Mammals indicative of open and seasonally arid environments show a significant increase in relative abundance at the close of the Neogene, shortly after 2 Ma. In South America, cursorial and grazing mammals dominated land mammal communities. As in Africa, South American mammals also show several episodes of high faunal turnover, with peaks around 3.2, 2.2 and 0.8 Ma. The 3.2 Ma peak is correlated with a diastrophic Andean phase; the peak at 2.2 Ma with a strong fall of temperature; and the 0.8 Ma peak with a change from wet and temperate climatic conditions to a brief span of dry and probably cold climatic conditions. Also, the 2.2 to 0.8 million-year span was characterized by the alternation of dry-cold and warm-wet climatic conditions. Although climate appears to be a critical factor in driving the evolution of mammalian communities in both continents, regional tectonics modulate the signal derived from the paleontological record.

Campbell, University of South Carolina, Spartanburg in the 1970's (Campbell, pers. comm.), fully articulated crabs herein tentatively identified as or closely allied to Zaops ostreum (Say, 1817) occur abundantly in strings of C. fornicata buried in apparent storm deposits of the Late Pliocene Yorktown Formation "Chuckatuck Bar". near the small village of Chuckatuck, Suffolk, Virginia. This bar trends N. 20 degrees to 25 degrees W., is about 2.4 km wide, more than 6.4 km long, has an axial thickness of about 20 meters, and is primarily composed of medium to coarse biofragmental sands (modified after G. H. Johnson and N. K. Coch, 1969). The presence of this crab in fossil or extant C. fornicata has not been noted before, and the occurrence of pinnotherids in other crepiduloid gastropods are rare. These minute, free-standing, exceedingly fragile fossil crabs occur in the interior of this fossil Crepidula, one or sometimes 2 per shell, with as many as four per string, in strings of up to 17 shells. Most appear to be immature or first crab-stage females along with a very low incidence of mature females and males. The first Crepidula of each string is often attached to the single valve of a small bivalve, like Spisula, suggesting that these strings were easily transported during severe storms before their apparent rapid burial and death by anoxia and/or starvation. These strings occur in concentrations of more than 50 per cubic decimeter. Preliminary findings suggest that this fossil relationship was much like that between living Z. ostreum and Crassostrea virginica (Gmelin, 1791) where the first crab-stage of this species invades this oyster in mid-summer, a time of potentially severe storms, thus also suggesting that such storms may have migrated along the Eastern United States during a "Pliocene summer" as well.

Because mineral delta (super 18) O signatures can yield fluid source characteristics, we analyzed oxygen isotopes in cathodoluminescence (CL)-zoned jadeitite samples, previously analyzed for trace elements by SIMS. Twenty delta (super 18) O analyses were made for 6 jadeitites from Guatemala, California, Japan, Burma, and Kazakhstan. Separates from 2 samples and Eiler et al.'s (1997) jadeite standard were also analyzed by laser fluorination. Four samples yielded delta (super 18) O from 8.18 to 9.89 per mil; two ranged from 4.45 to 7.07 per mil. Two samples are zoned in delta (super 18) O: in CJ-01 (Burma) bright green-CL zones (4.9 per mil; rich in Li, Rb, Ti, MREE, Zr) contrast with blue-CL zones (8.89 to 9.33 per mil, rich in Be); in sample 112552-1, (Japan), a bright green (4.45 per mil, rich in Li, Be, REE, Zr) zone again contrasts with red-blue zones (6.22 to 6.62 per mil, rich in Rb). Separates from 112552-1 yield delta (super 18) O of 6.63 to 7.07 per mil. T-estimates based on delta (super 18) O exchange between albite and jadeite range from 299 degrees (CJ-01, Burma) to 414 degrees C (112538, Guatemala), consistent with jadeitite-forming Ts predicted by phase equilibria and fluid inclusion data. As has been shown for other minerals, SIMS detects large variations of delta (super 18) O within (in this case, trace element- and CL-) zoned grains, which may go unnoticed in whole-rock samples or mineral separates. Globally, jadeitite-forming fluids apparently differ by as much as 5 per mil in their delta (super 18) O values. Jadeitite-forming fluids with such distinct delta (super 18) O characteristics may have originated from different depths within subducting oceanic crust (e.g., pillow basalt versus gabbro) that underwent seafloor alteration at different temperatures, as is documented for high P/T meta-ophiolitic terrains.

Although habitat instability was influenced by global climate dynamics, environmental change caused by local tectonic events leads to the question whether the rift valley was atypical of the environmental and evolutionary settings of early hominin populations elsewhere. After East Africa, East Asia provides the next longest, continuous record of early human evolution, spanning approximately the past 1.7 million years. Recent research in the Nihewan Basin gives magnetostratigraphic and chronological context indicating the persistence of early human toolmakers in northeast Asia, coincident with several wide climatic shifts over a period of at least 400,000 years during the early Pleistocene (Zhu et al. 2001). Excavations in mid-Pleistocene deposits of the Bose Basin, southern China, have focused on red laterized sediments long considered to be indicative of a stable Pleistocene habitat. This research has uncovered large cutting tools, similar to Acheulean handaxes of Africa, made by populations that likely colonized a markedly disturbed landscape following tektite deposition and forest burning 803,000 years ago (Hou et al. 2000; Potts et al. 2000). Although the tempo of change differed from that of volcanically-disturbed environments of East Africa, East Asian temperate and subtropical zones also underwent strong climatic fluctuation and episodic, drastic environmental change to which early hominin populations were apparently able to successfully adapt. Detailed comparison of early human adaptability to East African and East Asian environmental dynamics will eventually help evaluate the evolutionary history of hominin populations in these two regions.

In lawsonite eclogite, lawsonite occurs with omphacitic clinopyroxene as inclusions in garnet, indicating eclogite facies conditions during garnet growth. The inclusion assemblage of lawsonite eclogite includes phengite, biotite, zoisite, albite, rutile, zircon, allanite, and various sulfide minerals. A second generation of lawsonite and phengite (typically with sodic amphibole) occurs in irregular, undeformed patches. Experimentally derived P-T grids for lawsonite eclogite indicate minimum pressures of 20-25 kbar. Geothermometry on garnet rims and matrix clinopyroxene gives values from approximately 400-550 degrees C. Results from clinopyroxene inclusions with garnet cores yield slightly lower T = 350 to 450 degrees C. Variable major element, trace element and REE geochemistry indicates the metabasites encompass diverse protoliths, including MOR and primitive IA basalt. High initial 143Nd/144Nd (eNd = +8.8) and low 87Sr/86Sr (0.70379) of clinopyroxene suggests a depleted source, as expected from MORB. Preliminary Sm-Nd geochronology indicates that the lawsonite eclogites formed at 161+ or -20 Ma (2s). Ar-Ar geochronology on phengite indicates cooling of eclogite and jadeitite through approximately 350 degrees C at 113-125 Ma. Jadeitite veins from the same serpentinite slices contain unusual assemblages, which include lawsonite, pumpellyite, quartz, and rutile; these are estimated to have formed at T = approximately 100-400 degrees C and P = 5 to 20 kb. Occurrence of these coexisting rock types points to a very high pressure and cold origin for the terrain, especially considering the abundance of lawsonite and pumpellyite. This terrain is an excellent demonstration of lawsonite carrying water into the mantle, as has been predicted by experiments and thermal models. These data indicate a small-plate to continent collision (Chortis on Mexico) can yield near UHP conditions, probably via a precursor, oblique, long-lived subduction zone.

Observations of manatee foraging habits suggest that feeding is non-selective, but movement of manatees between different aquatic ecosystems may impart a seasonal pattern on the type of plants consumed by this species (i.e., seagrass vs. freshwater vegetation). Since the carbon isotope (delta (super 13) C) and hydrogen isotope (delta D) values of manatee tissues are controlled by the stable isotope composition of the animal's diet, compound-specific stable isotope measurement of delta (super 13) C and delta D values of cholesterol and other organic molecules that form over a relatively short period of time can track sub-annual changes in foraging habit and supplement information gained from other tissues that reflect multi-year dietary averages (e.g., collagen). Furthermore, stable isotope analysis of cholesterol extracted from ancient bones may shed light on the short-term feeding habitats of manatee populations prior to human contact. To determine whether the measurement of cholesterol delta (super 13) C and delta D values can provide short-term dietary information for manatees, we have begun collecting tissue samples from recently deceased manatees from the Indian River Lagoon along the eastern coast of Florida. From each individual, 3 tissues differing in metabolic turnover rate were selected for analysis including liver (fast turnover), muscle (intermediate turnover), and bone (slow turnover). Cholesterol extracted from each of these tissues will have formed within different periods of time over the course of the year, providing sub-annual records of seasonal dietary patterns based on variations in cholesterol delta (super 13) C and delta D values. Comparison of cholesterol isotope values with collagen values from the same individual will then provide a means to quantify the magnitude of seasonal dietary variation relative to long-term dietary preferences. By extending these analyses to recent and fossil material, future work could examine whether the feeding patterns of Florida manatees have changed significantly over time and, if so, whether human or environmental factors have contributed to this change.

Each element of this triad has been invoked to explain the magnitude of the Neoproterozoic-Cambrian metazoan radiation, but with no consensus on the relative significance of each element. Developmental innovation has received considerable attention, driven in part by the recognition of the extensive conservation of a variety of transcription factors and signaling molecules between Drosophila and vertebrates. The conserved elements include the well-known Hox and Pax-6 systems and a much broader array of genes. At the limit, these genes suggest a protostome-deuterostome ancestor (PDA) was a morphologically complex animal possessing eyes, segmentation, appendages, heart, complex nervous system, respiratory structures, and the complex morphogenetic pathways needed to produce them. In 2003 Eric Davidson and I suggested these highly conserved regulatory sequences are better understood as elements of a developmental toolbox associated with vectoral patterning, cell type specification and other more general developmental tasks, but in many cases without morphogenetic patterning. This view of the PDA suggests it may have been a much simpler animal than the extreme developmental position. If so, such animals would be unlikely to be preserved as trace or body fossils, and the PDA could substantially pre-date 555 Ma. The existence of a PDA with a diverse developmental toolkit, but evidently without many of the complex morphogenetic pathways apparent in Cambrian organisms suggests: 1) many of these morphogenetic pathways are clade-specific, as suggested by some developmental data; 2) that since the PDA predates 555 Ma, developmental innovation was likely not a significant factor in the breadth and rapidity of the Metazoan radiation; and 3) that ecological interactions played a key role.

Two different parameters, one physical and one molecular, can have a significant impact on apparent hydrogen exchange. The rapid rehydration of protein during sample preparation can now be largely controlled with continuous flow systems, and careful handling of samples can decrease the error contributed from adsorbed water. The range of molecular integrity that exists in collagen from fossil and subfossil bone spans the gamut from completely insoluble, unaltered protein to hydrolyzed, deaminated, decarboxylated, racemic remnant polymer. The amount of hydrogen exchanged during collagen preparation from bone varies significantly as a function of protein preservation, specifically helical content. The impact of widely disparate collagen preservation states on the observed hydrogen isotopic values in bone collagen is shown for a mid-Holocene burial site in east central Florida, where clear trends between human and faunal collagens can be seen through the noise of different amounts of hydrogen exchange.

A substantial tetrapod ichnofauna from strata of the Clear Fork Formation at Lake Kemp, Baylor County, Texas, augments the meager North American tetrapod ichnofauna of Leonardian age. The tracks at Lake Kemp occur in the informally-named Craddock Dolomite Member of the Clear Fork Formation, which is 12-15 m above the local base of the Clear Fork and of early Leonardian age. The track-bearing stratum is a 0.3-m-thick, ripple-laminated and trough-crossbedded, calcareous siltstone that also contains mud cracks, raindrop impressions and some land-plant impressions. We interpret the Craddock Dolomite as the feather-edge of a marine transgressive carbonate deposited along an irregular coastline marked by shallow bays or estuaries on the eastern shelf of the Midland basin. At Lake Kemp, the most common tracks are of small temnospondyls, and we assign them to Batrachichnus. The next most common are seymouriamorph tracks assigned to Amphisauropus, which can be assigned to large and small ichnospecies, A. latus Haubold and A. imminutus Haubold. Least common are araeoscelid tracks assigned to Dromopus. A sparse invertebrate ichnofauna consists of arthropod feeding and walking traces assigned to Diplichnites, Helminthopsis, Cochlichnus and ?Oniscoidichnus. The vertebrate (especially amphibian) and invertebrate traces indicate a freshwater setting at the time of track formation. The Lake Kemp tetrapod track assemblage is characteristic of the global Lower Permian tetrapod ichnofauna found in red beds, which is dominated by a handful of ichnogenera that include Batrachichnus, Limnopus, Amphisauropus, Dromopus, Varanopus, Hyloidichnus, Ichniotherium, Dimetropus and Gilmoreichnus. This assemblage is mostly the tracks of temnospondyls, diadectomorphs, seymouriamorphs, procolophonids and pelycosaurs. However, the abundance of Amphisauropus tracks at Lake Kemp is unusual, though it may only reflect the idiosyncracies of track preservation at a specific site.

Clay-hosted planktonics exhibit significantly lower delta (super 18) O values than chalk-hosted specimens, supporting the hypothesis that diagenetic alteration toward higher delta (super 18) O values may be most common in chalks. To estimate Cretaceous upper ocean temperatures, we have used clay-hosted foraminifera with glassy shells similar to those of foraminifera caught in plankton tows. In some cases, the excellent preservation of biogenic carbonate is supported by the presence in the same strata of ammonites with aragonitic shells. Oxygen isotopic analysis of a variety of near-surface dwelling species from closely sampled sequences yield delta (super 18) O values of approximately -3.5 to -4 in the Albian and early Cenomanian (subtropical ODP Sites 1050 and 1052), -3.9 to -4 in the late Cenomanian (tropical DSDP 144), -4.2 to -4.5 in the late Turonian (tropical DSDP 144), and -3.9 to -4.6 in the late Turonian (subpolar DSDP 511). Assuming equilibrium fractionation and a wide range of plausible water delta (super 18) O values, almost all the data (including subpolar Site 511) indicate upper ocean temperatures equal to or, in most cases, higher than modern tropical sea surface temperatures. This is true even if it is assumed that Cretaceous upper ocean delta (super 18) O everywhere was closer to the global mean ocean value (taken to be -1 to -1.25 per mil SMOW) than it is today, as is suggested by Cretaceous isotope tracer model experiments. The apparent warm Cretaceous equatorial temperatures from Demerara Rise (ODP 144) are especially remarkable if we consider that planktonic foraminifera live in the shallow subsurface and that waters in that region today cool rapidly below the surface because of upwelling.

During the Maastrichtian Site 1050 was located at approximately 30 degrees N latitude in the western North Atlantic. The Maastrichtian section shows dark-light color alternations that have been attributed to precessional cycles. In a previous study across the most prominent Maastrichtian cycles, light colored intervals were found to be associated with relatively high productivity, relatively cool temperatures, and higher relatively abundances of Heterolix spp. and Globigerinelloides spp.; darker intervals were associated with relatively low productivity, relatively warm temperatures, and higher relative abundances of Globotruncana spp. and Pseudoguembelina spp. Preliminary results suggest these relationships break down in an interval where cyclicity is less dramatic. Across low amplitude cycles in a younger interval from the same hole, we have found that light colored intervals are associated with the highest delta (super 13) C values for Heterolix globulosa, and Rugoglobigerina rugosa consistent with high relative productivity in these intervals. However, the largest variations in delta (super 13) C values are seen in Pseudoguembelina palpebra, and these values show no apparent relationship to cyclic color changes. Further, whereas bulk carbonate and H. globulosa have delta (super 18) O values that suggest the light intervals were relatively cool, delta (super 18) O values of the presumed surface dwellers R. rugosa and P. palpebra suggest, if anything, the opposite. Finally, most taxa studied have their peak abundances in a sample from a relatively light interval, but not in all samples from light interval. These results demonstrate that neither the local water column nor planktic foraminiferal distributions responded in a consistent fashion to Milankovitch-scale forcing. With further work on this interval, we believe we will find that certain taxa were relatively abundant during either high or low productivity intervals and that the complexity seen is due in part to variation in the surface mixed layer being out of phase with variation deeper in the water column.

At least three planktic and one benthic species per sample, selected at closely spaced intervals from the Globigerinelloides algerianus Zone (mid-Aptian) through uppermost Ticinella bejaouaensis Zone (uppermost Aptian), reveal a consistently low (<1.1%) vertical delta (super 18) O gradient, suggesting that the thermocline was weakly developed throughout this time. Benthic delta (super 18) O values show a slight positive increase from +0.5% during the mid-Aptian to +1.1% during the latest Aptian, then decrease to -0.2% during peak C (sub org) deposition in OAE 1b (Hedbergella rischi Zone, lowermost Albian). Assuming that the delta (super 18) O composition of Cretaceous seawater averaged -1.2% and polar ice sheets were absent or very small, we estimate that middle bathyal waters at this site ranged from 7-9 degrees C during the mid-late Aptian and warmed to 12 degrees C during OAE 1b peak C (sub org) deposition. Mid-late Aptian upper surface dwelling planktic delta (super 18) O values consistently range between +0.2 and -0.1%, then abruptly shift to -2.0% during the maximum OAE 1b C (sub org) deposition event. Using the same assumptions as above and no salinity correction, we estimate that mid-late Aptian upper surface waters ranged from 11-12 degrees C, then warmed to 20 degrees C during OAE 1b. An abrupt turnover of planktonic foraminifera, including extinction of large T. bejaouaensis and H. trocoidea and disappearance of species bearing distinctive pore mound wall textures, exactly corresponds with a 2% negative delta (super 13) C shift at the Aptian/Albian boundary and the base of OAE 1b. The simultaneous change in planktic foraminifer assemblages and stable isotope values indicates that the onset of OAE 1b involved major changes in the North Atlantic climate and oceanography. Determination whether these changes heralded the onset of global warmth will require further investigation.

To better understand this alteration style, we are studying Tertiary volcanic rocks at Creede, CO (an environment of epithermal Ag-Pb-Zn mineralization), the Harcuvar Mountains, AZ (the upper plate of a detachment fault), and Socorro, NM (an arid playa extensional environment), with petrographic and geochemical methods that include CL. These terrains underwent extensive low-T (95) K-feldspar, clay minerals, and quartz, and oxidation of magnetite and mafic minerals to hematite. CL documents multiple generations of quartz growth that helps to delineate complex metasomatic histories. Spectroscopy of quartz from these rocks is essential, because observed color is an unreliable provenance indicator. Relict igneous phenocrysts emit zoned CL in both the red and blue regions of the spectrum, yielding "purple" CL that may appear blue or red to the eye. Much fine-grained groundmass quartz in altered tuffs is non-luminescent. Bright red-luminescent quartz occurs as overgrowths on phenocrysts, in former melt inclusion structures and in the groundmass of some tuffs. The latter may reflect vapor phase crystallization, because it is seen primarily in lithophysae. Recrystallized groundmass quartz from the welded Willow Creek tuff (Creede) displays coarse-grained quartz with red CL. Hydrothermal vein quartz exhibits several CL colors, whereas quartz related to K-metasomatism is typically non-luminescent. For example, mineralization-related vein quartz at Creede shows oscillatory and sector zoned yellow, blue, and red CL; in contrast, vein quartz from K-metasomatized samples isolated from mineralization are non-luminescent. This may reflect lower-T growth of the latter. Trace element compositions of adularia from veins that also contain quartz with yellow CL differ from those of adularia that has replaced phenocrysts, suggesting distinct fluid-rock events. CL could prove useful as a prospecting tool in regions that display multiple alteration events.

However, the biological data is currently much better studied, both spatially and temporally, than the environmental data. Oceanographic studies are usually either broad in time or in space. In this study we use a new technique to investigate levels of seasonality associated with the closure of the isthmus using cupuladriid bryozoans. Cupuladriids are extremely abundant throughout the Neogene of Central America and studies on Recent colonies show that their skeletons record levels of ambient seasonality discernible through morphometric analysis. We used the extensive fossil cupuladriid collections of the Panama Paleontology Project (PPP) to investigate patterns of seasonality in the Caribbean and eastern Pacific over the last 10 million years. Data were restricted to either one or two PPP samples, thereby allowing regional-scale environmental inferences to be made. The results reveal the general pattern of diverging environments during isthmus closure that have led to Pacific waters being highly seasonal and instable due to upwelling and Caribbean waters being aseasonal and highly stable with no upwelling. These changes were punctuated by considerable regional heterogeneity and a substantial drop in Caribbean seasonality during the last 2Ma. Indeed, present-day Caribbean stability was not achieved until the end of the Pliocene, suggesting that some Caribbean coastal waters were still being affected by upwelling after final closure.

Very different forms occur adjacent to each other, usually with steep character gradients between them. The central east coast of Long Island, Bahamas has the greatest known diversity within the genus Cerion, with the entire, non-overlapping ranges of three endemic species flanked by a broader ranging species (4 transition zones on the order of 20-100 m) all contained within a 12 km region of coastline. In addition to our studies of the genetic variability of these taxa throughout their ranges and across these transition zones, we have sought to follow these geographic patterns back in time through excavation and analysis of the Holocene fossil record of these snails. We have excavated pits (to 2.35 m in depth) throughout this 12 km region of coastline, as well as sampled from sand quarry walls and erosion cuts. Cerion shells were plentiful throughout most levels in these sands. Cerion shells were individually dated by amino acid racemization analysis, using the D-alloisoleucine/L-isoleucine (A/I) ratio. The in situ rate of racemization was determined by calibration against a series of radiocarbon-dated shells. This, in turn, allowed estimation of individual shells from their A/I ratios. Corrections for radiocarbon age anomalies for the shells (due to ingestion of old carbonates) was based on radiocarbon analysis of live-collected, pre-bomb shells as well as by regression analysis of A/I values against uncorrected radiocarbon ages of fossils. These analyses showed that the oldest samples dated to ca. 4000 yr BP, and that complete temporal sequences up to the present were recovered from some of our excavation sites. In every case, a substantial mixture of shell ages was found at each level, with average age increasing with depth. Very substantial changes in shell morphology are documented in the temporal sequences constructed for most of the sites excavated. At every site, shells older than ca. 3000 yr are substantially different from living forms. More recent changes are also evident at most sites, with living individuals significantly larger than all but the most recent (<200 yrs) fossil shells. We evaluate several possible scenarios for the origin of the observed pattern of spatial and temporal variation in Cerion distribution.

Many alternative hypotheses have been proposed for the origin of the MFF materials, found along the equator of Mars between longitudes 135 and 230 E. THEMIS data provide new information to help test the proposed hypotheses. The daytime thermal infrared image I01665006 shows a cliff within a component of MFF (at 7.0 N, 218.5 E); near the top of the cliff is a horizontal layer that is measurably cooler than its surroundings. Cooler daytime temperatures are indicative of a higher competency than that of the surrounding cliff materials. The competent layer corresponds to an erosional embayment into the topmost portion of the cliff, indicating that the competent layer is much more resistant to erosion than the uppermost material. Both of these attributes are consistent with exposure of a welded zone in an ignimbrite, with enhanced erosion of the friable vapor-phase altered materials above the welded zone. The competent layer is consistent with MOC images of multiple dark horizontal bands visible on erosional scarps of other exposures of MFF materials. All of these features are more difficult to reconcile with the other proposed hypotheses of origin. This is the first physical properties evidence that directly supports the ignimbrite hypothesis, proposed in the 1980s based on Viking image analysis. Evidence for similar competent layers in other portions of MFF will be sought in THEMIS images from other MFF exposures.

Their use for the reconstruction of major changes in paleogeography and paleoceanography has been amply demonstrated. Some of the increased importance of ostracodes is due to new exploration via drilling and the discovery of new forms in the floors of sea and ocean basins. Some of it has been made possible by the development of the scanning electron microscope and attention to details in carapace morphology, particularly in mapping patterns of reticulation. The discovery that the shape of the carapace subscribes to architectural restraints of a membrane static-frame used in dome construction has introduced the possibility to describe it in functional and adaptive terms, and those principles are set forth here.

Mapping is being completed at 1:500,000 and is accompanied by assessment of drainage basin morphometry and hypsometry. The segmented Uzboi-Ladon-Margaritifer mesoscale outflow system drains about 9% of Mars and incises and fills as it crosses a series of ancient multi-ringed impact basins on the western flank of the Chryse Trough. By contrast, the well-integrated Samara and Parana-Loire Valles drain an area covering about 0.5% of the planet along the eastern flank of the Trough. The degraded Ladon and Holden multi-ringed impact basins are the oldest features in Margaritifer Sinus and their formation was followed by three widespread resurfacing events that deposited competent materials interpreted to be of sedimentary and/or volcanic origin on the basis of preserved wrinkle ridges and occasionally lobate morphology. The first two resurfacing events occurred during early Noachian heavy bombardment, whereas the third event took place during the middle to late Noachian and was coincident with waning highland volcanism. Incisement of all channels and valleys in the region occurred from late Noachian into the early Hesperian during a period of increased geomorphic activity elsewhere on Mars. Valley morphometry and hypsometry suggest evolution was dominated by precipitation-recharged ground water sapping with only limited contributions from runoff. A final, more localized resurfacing event during the early to middle Hesperian emplaced materials that always embay the channels and valleys. Channels and valleys converge on Margaritifer Basin, a depositional plain along the Trough axis that extends to the head of Ares Vallis and perhaps well beyond. Discharge into Margaritifer Basin led to ponding, subsurface infiltration, and storage of water that was released during subsequent collapse of Margaritifer and Iani Chaos in the early-to-mid Hesperian, thereby contributing to incisement of Ares Vallis. Hence, formation of Ares Vallis was the final stage in a long history of repeated water transport, storage, and discharge in the Margaritifer Sinus region.

Dust storms and dust devils have been observed in recent years, and dunes and ripple-like forms have been observed in many areas. Although it is not known whether or not dunes and ripples are still active, these aeolian forms provide information about the past (if not present) wind regime on Mars. Mars Orbiter Camera (MOC) images from Mars Global Surveyor have provided a view of dunes and ripples that was not previously available. Several authors have used MOC images to discuss the stratigraphic relationships between dunes and ripples and to compare their albedos. Shape measurements of terrestrial ripples have been used in comparisons to martian ripple forms in an attempt to determine exactly what type of aeolian bedform is represented by the ripple forms on Mars. It is possible to measure the crest spacing of ripple forms from MOC images, but heights of ripples have not been measured to date. The heights of martian dunes have only recently been measured using MOLA topographic data and stereo measurements. Smaller barchan dunes are approximately 30 m in height whereas larger dunes can be approximately 100 m. As more MOC images are released, stereo pairs with sufficient resolution and angular separation become available for attempts at stereo measurements of ripple heights. Here we report on results from the first height measurements of ripple forms on Mars. Although available image resolutions prevent measurement of smaller forms, ripples with crest spacing of approximately 38 m were measured to have heights of approximately 5.7 m. This gives a ripple wavelength to height ratio of approximately 6.7, whereas that ratio is approximately 15 for terrestrial ripples. If this ratio remains consistent for other areas on Mars, it would suggest that martian ripples are twice as tall as their terrestrial counterparts for a given ripple wavelength. The greater heights of martian ripples may be the result of the lower martian gravity and other factors.

Such bedforms are rare on Earth, and, in all cases, involve sedimentary materials of mixed size. The best Viking images hinted at their presence, and fostered research into possible terrestrial analogs. One of the first field analog sites to be considered lies atop the Mono Domes eruptive complex near Mammoth Mountain, California, where large fragments of pumice and smaller fragments of obsidian are sculpted into large ripple-like bedforms. Detailed grain size analysis from different locations on the bedforms was part of the initial study, as was marking bedforms with rebar in order to assess bedform migration over time, and placement of abrasion targets. The site was revisited in June, 2003, more than 22 years after the initial observations. Unfortunately, South Dome has been a popular OHV recreation site, despite closure by the BLM to all motorized traffic, and all of the abrasion targets and almost all of the rebar were damaged and/or removed. However, photographic documentation demonstrates than none of the larger bedform elements has moved significantly since they were first observed. Footprints and tire tracks were "repaired" naturally, and some changes were noted in the smallest of aeolian features, but the bedforms themselves are unchanged. Ripple crests were flattened in two test plot locations in 1981. In one, the fragments comprising the crest were removed by gentle raking; in the other, the fragments were pressed into the subsurface by treading on them heavily. Neither bedform crest has been restored since the plots were established. The apparent longevity of the Mono Domes bedforms is consistent with that of their potential martian analogs, which appear to be older and more durable than would be expected of aeolian bedforms developed in unconsolidated sediments.

Dietary adaptations vary from strict herbivory to pure carnivory. These adaptations have evolved independently several times within families, so evolution within the order is iterative. I used 2 databases to examine whether ecological adaptations have an effect on longevity or spatial distributions of fossil carnivores. Miocene hypercarnivorous species had, on average, the widest spatial distributions. Their temporal distributions were not significantly longer than those of other carnivores. Body size also had a significant interaction with maximum spatial distribution. Large-bodied carnivores, regardless of feeding adaptations, had larger geographical ranges, but did not have greater longevity. However, when all the data were pooled, temporal distribution had a significant correlation with spatial distribution. The position of hypercarnivores at the top of the food chain and their specialized adaptations for meat eating probably increased their extinction risk to the same level of more narrowly distributed, less specialized carnivores.

The most abundant fungal morphotypes of both ascomycetes and basidiomycetes were generalists found on all three hosts, but detrended correspondence analysis revealed distinct differences in fungal community composition among host trees. These differences among hosts were constant across census years. Randomization tests revealed that there were significantly fewer host-generalist fungi than expected for ascomycetes but not for basidiomycetes. These results indicate that host composition plays a role in structuring both ascomycete and basidiomycete fungal communities, but that the most successful fungal morphotypes are capable of colonizing multiple host species.

Conservation efforts focus on measuring species diversity and distribution, assessing biodiversity threats, and managing habitats to maintain that diversity. The accuracy of measuring species diversity depends on the quality and scale of the data. Recently indirect estimates of diversity based on the skilled opinions of international taxonomic authorities were used to define 25 global conservation hotspots [Myers et al. (2000) Nature 403: 853-858] and 871 ecoregions [Olson et al. (2001) Bioscience 51: 933-938]. These data, originating from first-hand fieldwork and museum study, are readily available, but not necessarily repeatable nor testable. If this type of information prevails for conservation purposes, it is critical that we test the quality of this information with verifiable data at finer scales (e.g., regional inventories, specimen records, and accumulated distribution data). Here we perform such a test for the hotspots and ecoregions found in the Indo-Pacific by comparing the estimates of the expert scientists with authenticated published diversity data on flowering plants. We found a high correlation between our counts of species richness and endemism with the experts' estimates, but surprisingly found less congruity among the seven families examined. A revised list of conservation priority regions based on our plant data is provided.

We mapped wildlands - large, unfragmented and undeveloped areas - asking: (1) Where are the largest wildlands that constitute elephant habitats? (2) What proportion of these wildlands is protected? (3) What is their potential for elephant conservation? Our study demonstrates that wildlands constitute only 51% of the Asian elephant range. Myanmar has the largest wildland ([similar]170,000 km super(2)), followed by Thailand and India. In Principal Components Analysis (PCA), the first two components explained 73% of the variation in fragmentation among ranges. We identified three fragmentation clusters from the PCA. Cluster A contains large ranges with unfragmented wildlands; cluster B includes ranges with well-developed transportation networks and large human populations; and cluster C contains ranges with severely fragmented wildlands. In cluster A, we identified four ranges with elephant populations >1000 animals: ARYO, MYUC, BNMH and BITE. Together with ranges that support >1000 elephants in cluster B, these A ranges have great potential for long-term elephant conservation. We propose that fragmentation clusters and population size can be used to identify different elephant monitoring and management zones.

In the heartland of Cajun culture, the Basin also supports a great diversity of wildlife and habitat. Nevertheless, the Basin has been subjected to decades of flood-control engineering and oil and gas development, leading to degradation and putrefaction. A burgeoning crawfish aquaculture industry further degraded the swamps. A new federal and state restoration project aims to restore the natural swamp hydrology, documented by hunters and trappers who plied the waters. However, restored waterways have increased the value of the land, and private owners have reduced access to Cajun fishermen.

Paper No. 34 N1 - Last updated - 2010-05-03 ER - TY - JOUR T1 - OH (super -) in synthetic and natural coesite AN - 51910080; 2004-001412 AB - The incorporation of hydrogen into the coesite structure was investigated at pressures ranging from 4.0-9.0 GPa and temperatures from 750-1300 degrees C using Al and B doped SiO (sub 2) starting materials. The spectra show four sharp bands (v (sub 1) , v (sub 2a) , v (sub 2b) , and v (sub 3) ) in the energy range of 3450-3580 cm (super -1) , consistent with the hydrogarnet substitution [Si (super 4+(T2)) +4O (super 2-) = va (super T2) +4OH (super -) ], two weak sharp bands at 3537 and 3500 cm (super -1) (v (sub 6a) and v (sub 6b) ) attributed to B-based point defects, and two weaker and broad bands at 3300 and 3210 cm (super -1) (v (sub 4) and v (sub 5) ) attributed to substitution of Si (super 4+) by Al (super 3+) +H. More than 80% of the dissolved water is incorporated via the hydrogarnet substitution mechanism. The hydrogen solubility in coesite increases with pressure and temperature. At 7.5 GPa and 1100 degrees C, 1335 H/10 (super 6) Si is incorporated into the coesite structure. At 8.5 GPa and 1200 degrees C, the incorporation mechanism changes: in the IR spectra four new sharp bands appear in the energy range of 3380-3460 cm (super -1) (v (sub 7) -v (sub 10) ) and the v (sub 1) -v (sub 3) bands disappear. Single crystal X-ray diffraction, Raman spectroscopy, polarized single-crystal and in situ high-pressure FTIR spectroscopy confirm that the new bands are due to OH (super -) in coesite. The polarization and high-pressure behavior of the v (sub 7) -v (sub 10) OH bands is quite different from that of the v (sub 1) -v (sub 3) bands, indicating that the H incorporation in coesite changes dramatically at these P and T conditions. Quantitative determination of hydrogen solubility in synthetic coesite as a function of pressure, temperature, and chemical impurity allow us to interpret observations in natural coesite. Hydrogen has not previously been detected in natural coesite samples from ultra high-pressure metamorphic rocks. In this study, we report the first FTIR spectrum of a natural OH-bearing coesite. The dominant substitution mechanism in this sample is the hydrogarnet substitution and the calculated hydrogen content is about 900+ or -300 H/10 (super 6) Si. The coesite occurs as an inclusion in diamond together with an OH-bearing omphacite. The shift of the OH-bands of coesite and omphacite to lower energies indicates that the minerals are still under confining pressure.

We report density and porosity measurements of 42 pieces of 30 ordinary chondrites and provide a quantification of the errors of the gas pycnometer method used in this study. Based on our measurements, we find that no significant correlation exists between porosity and petrologic grade, chemical group, sample mass, bulk and grain density, or shock level. To investigate variations in porosity and density between pieces of a meteorite, we examined tones from two showers, Holbrook and Pultusk. Examination of nine samples of Holbrook suggests relative homogeneity in porosity and density between pieces of this shower. Measurements of three samples of Pultusk show homogeneity in bulk density, in contrast to Wilkison and robinson (2000), a study that reported significant variations in bulk density between 11 samples of Pultusk. Finally, examination of two friable ordinary chondrites, Bjurbole and Allegan, reveal variability in friability and porosity among pieces of the same fall.

His publication illustrates a strew slide with many individuals, and no holotype was designated. Consequently, over the years, researchers have assumed that no holotype exists. A search of the Cushman Collection, however, discovered a slide labeled as holotype and it is so recorded in the Cushman Catalog of 1929. Here, this specimen is re-described and designated as a lectotype. All nine of the other surviving syntypes from the original collection in San Juan Harbor, Puerto Rico, now become paralecto-types. Hopefully, the designation of formal types for Ammonia tepida (Cushman) will help stabilize the taxonomy of this important species. Our study shows that the lectotype is morphologically distinguishable from other Ammonia types and that the distribution of Ammonia tepida is restricted to tropical shallow-water environments.

No fossil breeding sites of albatrosses were known previously. The timing of extinction of albatrosses in the North Atlantic was likewise unknown. Deposits that formed near present-day sea level along the southeastern shore of Bermuda contain remains of a former breeding colony and include intact eggshells and bones of embryos, juveniles, and adults of Short-tailed Albatross (Phoebastria albatrus), a critically endangered species now confined to a few islets in the northwestern Pacific Ocean. These deposits are correlated with the middle Pleistocene Lower Town Hill Formation, which at other sites have a radiometric age of 405,000 years ago. This equates with the marine isotope stage 11 interglacial, which culminated in a rise in sea-level to >+20 m. Bones of a juvenile Short-tailed Albatross were also found in beach deposits at +21.3 m from this same interglacial. We interpret the extirpation of albatrosses on Bermuda as probably resulting from lack of nesting sites protected from storm surges over the little emergent land that remained at the height of the marine isotope stage 11 sea level rise.

This study extends a previous investigation of the geochemistry and petrology of Gardnos impactites with additional sampling and a detailed investigation of the nature and possible origin of the carbonaceous material present.Two principal carbon components have been identified in Gardnos impactites: (1) impact-produced diamonds, 0.5 to 1 mu m in size, with a cubic crystal structure, predominantly hexagonal morphologies with platey layers and an estimated concentration of < 0.19 ppm in Gardnos suevites and (2) graphitic carbon ranging from poorly ordered to moderately crystalline.Geochemical data suggests that there are no suitable target rocks that could provide a single source for the carbon in Gardnos impactites. However, Raman spectroscopy, stable isotope analysis and transmission electron microscopy of the impact diamonds and graphitic carbon suggests that there were at least two episodes of C emplacement in Gardnos impactites: an impact-related incorporation and shock transformation of graphitic material from target rocks followed by later mobilization of C, possibly during postimpact cooling or later regional metamorphism.

Cladistic analyses of these sequences depict P. micrococcus as a polyphyletic composite of five well-supported clades. Sequence divergences among these clades and subclades imply the possible occurrence of as many as seven or eight cryptic species in addition to P. micrococcus. Our finding that P. micrococcus contains multiple, genetically distinct and geographically restricted lineages suggests that diversification within this highly speciose aquatic genus has been structured in large part by the operation of terrestrial barriers to gene flow. However, these sequence data also indicate that recent dispersal among hydrographically separated areas has occurred within one of these lineages, which we attribute to passive transport on migratory waterbirds.

During the 1980s, however, several natural disturbances changed the reef's community structure. We evaluated historical changes in coral cover and for the first time provide quantitative evidence of a large-scale process of reef degradation. This process started long before the onset of these disturbances as a result of demographic growth and the traditional practices of the Kuna people. Living coral cover declined 79% in 30 years (1970-2001 ) while the indigenous population increased 62%. We measured 20 km of seawall built with mined reef corals (16,000 m super(3) ) and an increase in island surface area of 6.23 ha caused by coral land filling. Consequently, coastal erosion has increased as a result of the lack of a protective natural barrier and a 2.0 cm/year local increase in sea level. Coral-mining and land-filling practices to accommodate population expansion and mismanagement of resources have significantly modified the reef ecosystem and will have serious long-term consequences. We propose eight priority conservation areas within the Indian reserve, based on reef conservation status. The Kuna people and their leaders are considering a cultural change, which may include a gradual and organized migration to the mainland, and have optimistically accepted our results.Original Abstract: Antes de 1980, se consideraba que los arrecifes coralinos eran relativamente estables y sanos en Kuna-Yala, en el Caribe panameno. Sin embargo, durante la decada de 1980, varias perturbaciones naturales cambiaron la estructura de la comunidad arrecifal. Evaluamos cambios historicos en la cobertura de coral y por primera vez proporcionamos evidencia cuantitativa de un proceso de degradacion de arrecifes a gran escala. Este proceso comenzo mucho antes del inicio de estas perturbaciones, debido al crecimiento demografico y a las practicas tradicionales de los Kuna. La cobertura de coral vivo decrecio en un 79% en 30 anos ( 1970-2001 ) mientras que la poblacion indigena incremento en un 62%. Medimos un muro de contencion de 20 km construido con corales ( 16,000 m super(3) ) y el incremento de 6.23 ha en la superficie de la isla por el relleno con material coralino. En consecuencia, la erosion de la costa se ha incrementado debido a la falta de una barrera natural de proteccion y el incremento local de 2.0 cm/ano del nivel del mar. La extraccion de coral y las practicas de relleno de terrenos para acomodar la expansion poblacional y el manejo inadecuado de recursos han modificado al ecosistema arrecifal significativamente y tendran serias consecuencias a largo plazo. Con base en el estatus de conservacion del arrecife proponemos ochos areas prioritarias de conservacion dentro de la reserva Indigena. Los Kuna y sus lideres estan considerando un cambio cultural, que puede incluir una migracion gradual y organizada al continente, y han aceptado nuestros resultados con optimismo.

Because it is widely used as an analytical tool and is a major reference for impact assessments on vegetation, it is important that the RDB be as comprehensive and up to date as possible. This study is an attempt to cross-check the listings in the RDB using vegetation inventories and another reference manual, the Atlas of Endemics of the Western Ghats, India [Ramesh and Pascal 1997. Atlas of Endemics of the Western Ghats (India). French Institute of Pondicherry, India]. Field inventories across the Western Ghats gave an estimate of the species relative abundances and the Atlas provided quantitative information on the number of records for the endemic species in herbaria, literature, and during field surveys. The results of this analysis indicate that the RDB and the Atlas agree statistically regarding the conservation status of endemic trees. However, the proportion of threatened species per Atlas record category behaves erratically, indicating that some threatened endemic trees are not listed in the RDB. Our results suggest that the status of threatened plant species should be reexamined on a priority basis using quantitative methodology.

In this study we combine the two fields to examine the evolution of reproductive isolation in the genus Heliocidaris . Heliocidaris tuberculata develops indirectly via a feeding larva, whereas the only other species in the genus, H. erythrogramma , has evolved direct development through a nonfeeding larva. We estimated the time of divergence between H. erythrogramma and H. tuberculata from mitochondrial DNA divergence, quantified levels of gametic compatibility between the two species in cross-fertilization assays, and examined the mode of evolution of the sperm protein bindin by sequencing multiple alleles of the two species. Bindin is the major component of the sea urchin sperm acrosomal vesicle, and is involved in sperm-egg attachment and fusion. Based on our analyses, we conclude that: the two species of Heliocidaris diverged less than five million years ago, indicating that direct development can evolve rapidly in sea urchins; since their divergence, the two species have become gametically incompatible; Heliocidaris bindin has evolved under positive selection; and this positive selection is concentrated on the branch leading to H. erythrogramma . Three hypotheses can explain the observed pattern of selection on bindin: (1) it is a correlated response to the evolution of direct development in H. erythrogramma ; (2) it is the result of an intraspecific process acting in H. erythrogramma but not in H. tuberculata ; or (3) it is the product of reinforcement on the species that invests more energy into each egg to avoid hybridization.

The increase took place in three stages, and began as an increase in the size of established groups. The next two stages of population increase were due to the formation of new groups and their subsequent increases in size. These two stages likely occurred because of habitat regeneration, which increased the areas where newly formed groups could establish home ranges. The population decline of 74% was most likely due to disease. However, new groups died out more rapidly than established groups, indicating that food shortages, especially in recently regenerated areas, may also have contributed to the population crash. The food shortages could have been caused by unpredictable periods of drought, which may explain the irregular size fluctuations of the study population. Since many howler species show irregular size fluctuations and sharp declines, their demographic features may reflect adaptations to unpredictable events like droughts and disease epidemics. On this premise we explain the preponderance of unimale groups and female-biased birth sex ratios at low densities and the dispersal of both sexes as adaptations for increasing a population rapidly after a decline. Within the population, mortality of small juvenile females was higher in multimale than in unimale groups, though medium juvenile and older immature females were better represented in multimale than in unimale groups. These results may be explained in terms of group composition and the mating systems in red howlers.

Population genetic structure and divergence was investigated for four closely related species surveyed across nine localities in Costa Rica and Panama. DNA sequence data were collected from a mitochondrial gene (ND2) and a nuclear gene (c-myc). Phylogenetic analyses yielded concordant results between loci, with reciprocal monophyly of mitochondrial DNA haplotypes for all species and of c-myc haplotypes for three of the four species. Estimates of genetic differentiation among populations (F sub(ST)) based upon mitochondrial data were always higher than nuclear-based F sub(ST) estimates, even after correcting for the expected fourfold lower effective population size (N sub(ie)) of the mitochondrial genome. Comparing within-population variation and the relative mutation rates of the two genes revealed that the N sub(ie) of the mitochondrial genome was 15-fold lower than the estimate of the nuclear genome based on c-myc. Nuclear F sub(ST) estimates were approximately 0 for the most proximal pairs of populations, but ranged from 0.5 to 1.0 for all other pairs, even within the same nominal species. The nuclear locus yielded estimates of N sub(e) within localities on the order of 10 super(5). This value is two to three orders of magnitude larger than any previous N sub(ie) estimate from frogs, but is nonetheless consistent with published demographic data. Applying a molecular clock model suggested that morphologically indistinguishable populations within one species may be 10 super(7) years old. These results demonstrate that even a geologically young and dynamic region of the tropics can support very old lineages that harbour great levels of genetic diversity within populations. The association of high nucleotide diversity within populations, large divergence between populations, and high species diversity is also discussed in light of neutral community models.

Of 715 adult frigatebirds marked on Tern Island and Johnston Atoll, 21.3% were resighted at other frigatebird colonies at least 582 km away. Mark-resight data indicated regular movement of males and females between Tern Island and Johnston Atoll (873 km apart), and less frequent movements to other islands; no birds marked on Tern or Johnston were seen on Christmas Island, but one was seen in the Philippines, 7627 km from where it was marked. Despite the regular occurrence of interisland movements, Bayesian analyses of AFLP data showed significant genetic differentiation between Tern Island and Johnston Atoll, and more pronounced differentiation between these two islands and the more distant Christmas Island. The AFLP profiles of three birds breeding on Tern Island fell within the profile-cluster typical for Christmas Island birds, both in a nonmetric multidimensional scaling analysis and in a population assignment test, suggesting dispersal events from Christmas Island to Tern Island. Several factors could explain the persistence of genetic structure despite frequent movements between colonies: many movements occurred during the nonbreeding season, many breeding-season movements did not involve mate-acquisition behaviours and individuals that do disperse may be selected against, as suggested by morphometric differences between colonies. The persistence of genetic structure among breeding colonies despite significant interisland movements suggests limits to the effectiveness of migration as a homogenizing force in this broadly distributed, extremely mobile species.

Although flow paths across the divide between the Agassiz and Nipigon basins were numerous, eastward releases from Lake Agassiz to glacial Lake Kelvin (modern Lake Nipigon) were channeled downslope into a relatively small number of major channels that included the valleys of modern Kopka River, Ottertooth Creek, Vale Creek, Whitesand River, Pikitigushi River, and Little Jackfish River. From Lake Kelvin, these waters overflowed into the Superior basin. The numerous lowerings in lake level between stages of the Nipigon Phase, controlled by topography and the position of the retreating southern margin of the Laurentide Ice Sheet, had magnitudes of between 8 and 58 m, although some of these drawdowns may have occurred as multiple individual events that could have been as small as several metres. The total volumes of water released in association with these drops were as great as 8100 km (super 3) , and for all Nipigon stages were probably between about 140 and 250 km (super 3) per metre of lowering. The topographic reconstructions demonstrate that Lake Agassiz occupied the area of glacial Lake Nakina (located northeast of modern Lake Nipigon) by the The Pas stage (ca. 8000 (super 14) C years BP) and that Lake Agassiz drainage through the Nipigon basin to the Great Lakes ended before the succeeding Gimli stage.

In this paper, we examine water-quality data for isolated wetlands in three hydrogeomorphic classes (depressions, slopes, flats). Some isolated wetlands are dominated by atmospheric exchanges and have little ground-water or surface-water connections with adjacent systems. Other isolated wetlands are dominated by ground-water inputs and have intermittent or continuous hydrologic connections to adjacent systems. Water-quality characteristics of isolated wetlands are highly variable and depend primarily on the sources of water, substrate characteristics, and land uses associated with the wetland watershed. We were unable to identify any general pattern of water-quality characteristics within or between isolated wetlands in the three hydrogeomorphic classes. Alteration of hydrologic conditions (e.g., ditching, filling), however, usually results in increased nutrient export to downstream systems. From a water-quality perspective, we conclude that so-called isolated wetlands are rarely isolated, and isolation is a term that is not very useful from an ecosystem perspective. Isolated wetlands are nutrient sinks and, because most are hydrologically connected to other waters and wetlands, the loss of isolated wetlands would potentially have negative impacts on the water quality of downstream systems.

The delta (super 13) C and delta (super 15) N of a taphonomic series of Rhizophora mangle L. (Red mangrove) leaves were analyzed from Twin Cays, Belize, to facilitate reconstruction of past mangrove ecosystems. On Twin Cays, fresh leaves of dwarf R. mangle trees ( approximately 0.5 m high) were found to have more negative delta (super 15) N values (mean = -10 per mil) and more positive delta (super 13) C values (mean = -25.3 per mil) compared to tall R. mangle trees (mean delta (super 15) N = 0 per mil, delta (super 13) C = -28.3 per mil). These isotopic differences can be related to nitrogen and phosphorus availability [Ecology 83 (2002) 1065]. We investigated three taphonomic stages in the fossilization of R. mangle leaves into peat with the following: (1) senescent leaves; (2) fallen leaves on the surface of the peat; and (3) sub-fossil leaves found within mangrove peat. In addition, by examining natural leaf assemblages we established that delta (super 13) C and delta (super 15) N of R. mangle leaves were not altered during senescence, despite a significant (50%) decrease in the N%. Modern dwarf and tall trees could still be identified from delta (super 13) C and delta (super 15) N analyses of the leaf assemblages found directly below a tree. Dwarf and tall trees could also be identified from delta (super 13) C analyses of leaves that had decomposed for four months. Although dwarf and tall trees could not be statistically separated after four months according to delta (super 15) N analyses, leaves with very negative delta (super 15) N (-7 per mil) were only collected below dwarf trees. Leaf fragments were present in approximately 50 cm long cores of peat from four sites on the island, and their isotopic compositions were determined. The ranges of delta (super 13) C (-29 to -22 per mil) and delta (super 15) N (-11 to +2 per mil) values from sub-fossil leaves were similar to the ranges from modern leaves (delta (super 13) C = -29 to -23 per mil, delta (super 15) N = -11 to +1 per mil). The sub-fossil leaf isotopic compositions were independent values, in comparison to the uniform values of the surrounding peat.

The ( (super 10) Be/ (super 9) Be) (sub 0) ratios range from approximately 0.36X10 (super -3) to approximately 0.77X10 (super -3) and are similar to those found by previous workers. The ( (super 10) Be/ (super 9) Be) (sub 0) ratios do not correlate in a temporal fashion with ( (super 26) Al/ (super 27) Al) (sub 0) , suggesting that (super 10) Be and (super 26) Al were produced by different mechanisms. An examination of possible sources for the short-lived radionuclides indicates that production of (super 10) Be was almost certainly by particle irradiation, possibly within the solar system, and was probably accompanied by significant production of (super 41) Ca and (super 53) Mn. In contrast, all of the (super 60) Fe, most of the (super 26) Al, and some of the (super 53) Mn were probably produced in stars and were imported into the solar system within presolar dust grains.

Our GOME NO sub(2) retrieval improves on previous work by accounting for scattering and absorption of radiation by aerosols; the effect on the air mass factor (AMF) ranges from +10 to-40% depending on the region. Our AMF also includes local information on relative vertical profiles (shape factors) of NO sub(2) from a global 3-D chemical transport model (GEOS-CHEM); assumption of a globally uniform shape factor, as in most previous retrievals, would introduce regional biases of up to 40% over industrial regions and a factor of 2 over remote regions. We derive a top-down NO sub(x) emission inventory from the GOME data by using the local GEOS-CHEM relationship between NO sub(2) columns and NO sub(x) emissions. The resulting NO sub(x) emissions for industrial regions are aseasonal, despite large seasonal variation in NO sub(2) columns, providing confidence in the method. Top-down errors in monthly NO sub(x) emissions are comparable with bottom-up errors over source regions. Annual global a posteriori errors are half of a priori errors. Our global a posteriori estimate for annual land surface NO sub(x) emissions (37.7 Tg N yr super(-1)) agrees closely with the GEIA-based a priori (36.4) and with the EDGAR 3.0 bottom-up inventory (36.6), but there are significant regional differences. A posteriori NO sub(x) emissions are higher by 50-100% in the Po Valley, Tehran, and Riyadh urban areas, and by 25-35% in Japan and South Africa. Biomass burning emissions from India, central Africa, and Brazil are lower by up to 50%; soil NO sub(x) emissions are appreciably higher in the western United States, the Sahel, and southern Europe.

These small desert foxes are nocturnal and spend the day in an underground den. Mated pairs often shared the same den on the same day. However, on days when they did not share the same den, mated pairs did not occupy dens that were closer together (or farther apart) than expected by chance. Closely related foxes on adjacent home ranges also occasionally shared dens. However, foxes living on adjacent home ranges, even when closely related, also did not occupy dens that were closer together or farther apart than expected by chance.

For marine organisms with planktonic larvae, much of this information can only be obtained through the determination of divergence between populations. We evaluated the importance of ocean barriers by studying the mitochondrial DNA phylogeography of Tripneustes, a pantropical genus of shallow water sea urchin. A region of cytochrome oxidase I (COI) was sequenced in 187 individuals from locations around the globe. The COI phylogeny agreed with a previously published phylogeny of bindin that barriers important to the evolution of Tripneustes are: (1) the cold water upwelling close to the tip of South Africa, (2) the Isthmus of Panama, (3) the long stretch of deep water separating the eastern from the western Atlantic, and (4) the freshwater plume of the Orinoco and the Amazon rivers between the Caribbean and the coast of Brazil. These barriers have previously been shown to be important in at least a subset of the shallow water marine organisms in which phylogeography has been studied. In contrast, the Eastern Pacific Barrier, 5000 km of deep water between the central and the eastern Pacific that has caused the deepest splits in other genera of sea urchins, is remarkably unimportant as a cause of genetic subdivision in Tripneustes. There is also no discernible subdivision between the Pacific and Indian Ocean populations of this genus. The most common COI haplotype is found in the eastern, central, and western Pacific as well as the Indian Ocean. Morphology, COI, and bindin data agree that T. depressus from the eastern Pacific and T. gratilla from the western Pacific are, in fact, the same species. The distribution of haplotype differences in the Indo-Pacific exhibits characteristics expected from a sea urchin genus with ephemeral local populations, but with high fecundity, dispersal, and growth: there is little phylogenetic structure, and mismatch distributions conform to models of recent population expansion on a nearly global scale. Yet, comparisons between local populations produce large and significant F ST values, indicating nonrandom haplotype distribution. This apparent local differentiation is only weakly reflected in regional divergence, and there is no evidence of isolation by distance in correlations between F ST values and either geographical or current distance. Thus, Tripneustes in the Indo-Pacific (but not in the Atlantic) seems to be one large metapopulation spanning two oceans and containing chaotic, nonequilibrium local variation, produced by the haphazard arrival of larvae or by unpredictable local extinction.

A total of 84 adults captured in two caves exhibited little genetic differentiation between caves (F sub(ST) = 0.008). Average relatedness among adult females in 10 harem groups was very low (R = 0.014 plus or minus 0.011), providing no evidence of harem structure. Dominant and subordinate males shared paternity in large groups, while dominant and satellite males shared paternity in smaller groups. However, our results suggest that male rank influences paternity. Dominant males fathered 69% of 40 offspring, followed by satellite (22%) and subordinate males (9%). Overall adult male bats are not closely related, however, in large harem groups we found that subordinate and dominant males exhibited relatedness values consistent with a father-offspring relationship. Because dominant and subordinate males also sired all the pups in large groups, we propose that their association provides inclusive fitness to them.

However, the molecular genetic variability of most neotropical primates is not well known. Therefore, we describe 13 primers for the amplification and sequencing of the mitochondrial control region that were developed for Alouatta caraya. Six of these primers gave unique bands on four other platyrrhine species (Alouatta palliata, Ateles paniscus, Ateles belzebuth and Saimiri boliviensis) showing their utility for control region amplification and sequencing in these platyrrhine species.

In 1986 residents along the shore of Lake Nyos died of a mysterious mass asphyxiation, fulfilling ancient geomythological prophesies about this region. The scientists who flocked to the craters determined that gases trapped deep in the waters accumulated and exploded in a lethal emission. A similar incident occurred at a nearby lake in 1984, killing 47. Scientists have concluded that an accumulation of carbon dioxide, kept under pressure from the lake waters, was responsible. The constant temperature of this equatorial lake increased the pressure. The detonation of accumulated carbon dioxide may have occurred through a rockslide, an unexpected drop in air temperature which would cause the surface water to cool or sink, or a strong wind. Vent pipes have been installed to relieve some of the pressure.

Once literally hidden cities, they remain steeped in Cold War culture and ideology, yet they face uncertain futures as weapons production needs change, hazardous waste dangers become more apparent and homeland security is threatened. 'Atomic museums' established at these and other sites have become focal points of such dilemmas. Their evolving interpretations of America's atomic heritage play a significant role in shaping public understanding of the Bomb.

We compiled records, extending back thousands of years, of the status and trends of seven major guilds of carnivores, herbivores, and architectural species from 14 regions. Large animals declined before small animals and architectural species, and Atlantic reefs declined before reefs in the Red Sea and Australia, but the trajectories of decline were markedly similar worldwide. All reefs were substantially degraded long before outbreaks of coral disease and bleaching.

Rhonite after kaersutite has a more NaSi-rich/CaAl-poor composition, lower Ti, and formed at higher oxidation ( approximately NNO) conditions than rhonite occurring as microphenocrysts in basanite. Comparison with experimentally determined rhonite stability in understaturated alkali basalt and as reaction product after Ti-amphibole indicates that the Mount Sidley rhonite (and associated minerals) formed between 1090 and 1190 degrees C at <0.5 kbar, presumably during temporary residence of the xenoliths in a shallow magma chamber below the volcanic edifice.

We argue that relative sea level and sea surface fingerprints local to such events provide a potentially powerful, integrated diagnostic for the mass imbalance. For example, we demonstrate, using an inference of glacier mass balance near Alaska over the last 50 years, that the present-day relative sea level fall at nearby sites can reach amplitudes that are approximately 2 orders of magnitude greater than the ongoing eustatic sea level rise associated with the melting. The peak sea surface subsidence is a factor of approximately 15 greater than the eustatic amplitude. We find that the predicted present-day sea surface change arising from the 50-year loading history is sensitive only to the ongoing rate of accelerated melting. In contrast, the present-day relative sea level fingerprint becomes increasingly sensitive to the "history" of the recent loading when the viscosity of the asthenosphere adopted in the prediction is progressively reduced below 10 (super 20) Pa s. Specifically, the relative sea level fingerprint becomes more localized, and reaches higher amplitudes, close to the glacier system as viscous effects become active. Our results have application in efforts to constrain small glacier mass balance using tide gauge records of relative sea level change or satellite-derived constraints on sea surface (geoid) rates.

Projected increases in carbon dioxide and temperature over the next 50 years exceed the conditions under which coral reefs have flourished over the past half-million years. However, reefs will change rather than disappear entirely, with some species already showing far greater tolerance to climate change and coral bleaching than others. International integration of management strategies that support reef resilience need to be vigorously implemented, and complemented by strong policy decisions to reduce the rate of global warming.

Its original allocation to the C. nigrescens group recently was questioned based on several cranial characters the species appeared to share with some members of the C. thomasi group. We review characteristics of the C. nigrescens and C. thomasi groups, and we describe the humerus of C. colombiana and the humerus and manus of C. medellinia.

In contrast, biological invasions are occurring daily in the US and have significant impacts on human health, agriculture, infrastructure, and the environment, yet they receive far less attention and fewer resources. Scientists and the US government must work together to implement a comprehensive approach to biosecurity that addresses not only bioterrorism, but also the more common incursions of invasive alien species. This approach should also address the potential for the deliberate use of invasive alien species as agents of bioterrorism. To achieve these goals, it will be necessary for the relevant government institutions to acknowledge and include prevention, early detection, and rapid response to species incursions as central mission themes. In addition, the scientific community, industry, and the public must work together to ensure that the necessary technology and information systems are readily available.

In cases in which a prey species exhibits different responses to various predator species, such changes in predator identity may have population-wide consequences. Our goals were to determine (1) whether mortality of and refuge use by the grass shrimp, Palaemonetes pugio, were predator-specific, and (2) how effects of prey size and habitat interacted with predator type. Striped bass (Morone saxatilis) exerted twice as much predation pressure as mummichog (Fundulus heteroclitus), although not equally as great on large (female) and small (male) shrimp. Mummichog, which fed preferentially on large shrimp, forced a partitioning of habitat between the two shrimp size classes. In contrast, large and small shrimp occupied similar habitats when subjected to striped bass, which fed on both size classes equally. Refuge use of grass shrimp depended on predator type. In the presence of mummichog, which occupied shallower depths in the water column than striped bass, shrimp stayed deep and close to structural habitat. Striped bass, which were deeper, caused shrimp to move high in the water column away from structural habitat. When both predators were present, shrimp distribution was similar to that when only striped bass were present, striped bass predation rate was enhanced, and overall mortality was higher than with either predator alone. Results suggest that at times when mummichogs are the dominant predators, large (female) shrimp experience higher predation than small (male) shrimp and are physically separated from their potential mates. When striped bass are more abundant, male and female shrimp may share a similar, shallow, less structure- oriented distribution and be subjected to higher mortality. When both predators are present, mortality rates may be higher still. This predator-, size-, and habitat-specificity of grass shrimp behavior suggests significant population and distribution consequences of fluctuating predator guilds and fluctuating cover of structural habitats in the field.

The effect of dry season drought on survival and leaf-area change of first year seedlings of 28 species of co-occurring woody tropical plants was experimentally quantified in the understory of a tropical moist forest. The seedlings were subjected to a drought or an irrigation treatment in the forest for 22 weeks during the dry season. Drought decreased survival and growth (assessed as leaf-area change) in almost all of the species. Both survival and leaf-area change in the dry treatment ranged fairly evenly from 0% to about 100% of that in the irrigated treatment. In 43% of the species the difference between treatments in survival was not significant even after 22 weeks. In contrast, only three species showed no significant effect of drought on leaf-area change. The effects of drought on species' survival and growth were not correlated with each other, reflecting different strategies in response to drought. Seedling size at the onset of the dry season had no significant effect on species' drought response. Our study is the first to comparatively assess seedling drought resistance in the habitat for a large number of tropical species, and underlines the importance of drought for plant population dynamics in tropical forests.

The inquilines are among the most specialised social parasites, because they are dependent on being fully integrated into their host's colony throughout their lives. They are usually relatives of their host and so share ancestral characteristics (Emery's rule). Closely related inquiline-host combinations offer a rare opportunity to study trade-offs in natural selection. This is because ancestral adaptations to a free-living state (e.g. the production of a worker caste) become redundant and may be replaced by novel, parasitic traits as the inquiline becomes more specialised. The dynamics of such processes are, however, unknown as virtually all extant inquiline social parasites have completely lost their worker caste. An exception is Acromyrmex insinuator, an incipient permanent social parasite of the leaf-cutting ant Acromyrmex echinatior, In the present study, we document the size distribution of parasite and host workers and infer how selection has acted on A. insinuator to reduce, but not eliminate, its investment in a worker caste. We show that the antibiotic producing metapleural glands of these parasite workers are significantly smaller than in their host counterparts and we deduce that the metapleural gland size in the host represents the ancestral state. We further show experimentally that social parasite workers are more vulnerable to the general insect pathogenic fungus Metarhizium than are host workers. Our findings suggest that costly disease resistance mechanisms are likely to have been lost early in inquiline evolution, possibly because active selection for maintaining these traits became less when parasite workers had evolved the ability to exploit the collective immune system of their host societies.

Without the thinning of periodic fires, these forest tracts are much more vulnerable to catastrophic wildfires--which have been very much in evidence in the past decade. While the US Forest Service has responded by promoting preventive burning, and proposed thinning programs, environmentalists are concerned about continued exploitation for forest resources under the guise of thinning. The behaviors and patterns of extreme forest fires show the risks and potential tragedies of inaction.

These behaviors reflect a high level of social concern, and replace the "killer ape" stereotype that has often been extended to explain human aggression and warfare. Dutch researcher Frans de Waal, an expert on primate behavior, has worked with chimpanzees in captivity for many years. He identifies many tactics adopted by his subjects to smooth over aggression. Humor, sharing, and appeasing behaviors are all evident, in addition to fights, challenges, and exchanges of favors.

Subtidal females averaged 1015.2 eggs mm super(-1) body length (range 0 to 2000 eggs mm super(-1)), while intertidal females averaged 607.4 eggs mm super(-1) (range 0 to 1520 eggs mm super(-1)). Mean egg diameters were not significantly different between worms from the 2 habitats, ranging between 90.4 mu m (SD = 3.7) and 89.5 mu m (SD = 4.3) for intertidal and subtidal worms respectively. Inter- and intra-census comparisons of egg diameter, fecundity and adult length revealed few statistically significant relationships, suggesting that intertidal and subtidal worms were the same age. Adult lengths in both habitats did change seasonally. The smallest adult worms were found shortly after massive fall recruitment replaced a large percentage of individuals in both intertidal and subtidal populations. Stepwise multiple regression indicated that 76.2% of the variance in intertidal fecundity was explained by a negative correlation with wave height (40.4%), and a positive correlation with day length (34.7%). In contrast, 85.5% of the variance in subtidal fecundity was explained by a positive correlation with day length (77.4%), and a negative correlation with chlorophyll a concentration (8.1%). While habitat-specific differences in energy available for gametogenesis probably contribute towards the observed fecundity trends, the force of crashing waves could also influence fecundity, as it may affect frequency of spawning in intertidal but not subtidal habitats.

Experimental tests of whether bird predation on arthropods can reduce plant damage, however, are few and restricted to relatively low-diversity systems. Here, we describe an experimental test in a diverse tropical forest of whether birds indirectly defend foliage from arthropod herbivores. We also compare how the indirect effects of bird predation vary with different levels of foliage productivity in the canopy vs. the understory. For three Neotropical tree species, we observed that birds decreased local arthropod densities on canopy branches and reduced consequent damage to leaves. In contrast, we observed no evidence of bird-arthropod limitation on conspecific saplings in the less productive understory of the same forest. Our results support theory that predicts trophic cascades where productivity is high and suggest that birds play an important role in Neotropical communities by means of their indirect defense of some canopy tree species.

This species is found from the upland pinelands to the mangrove forests of Florida. Dense Schinus infestations have the capacity to displace native species, reduce species diversity and been shown to reduce faunal use of the community. The purpose of this study was to determine if gas exchange patterns of Schinus were significantly different from native species. This work was part of a larger study to determine if the exotic's physiology contributed to its presence in two upland communities of South Florida. The first was an endemic rock pineland community and the second, a disturbed previously farmed area where Schinus was the canopy dominant. Schinus gas exchange, leaf nitrogen and carbon stable isotope contents were contrasted with four native species for one wet and dry season. Schinus tended to have higher assimilation (A), mesophyll conductance (gm), intrinsic water-use efficiency (WUE) and photosynthetic nitrogen-use efficiency (PNUE) than native species in the pineland site during the wet season but these differences were not statistically significant. There were also no significant differences in conspecific plant responses between the two communities. Seasonal differences were, however, significant for most of the gas exchange parameters at either one or both of the study sites. Wet season A, gm, nitrogen concentration ([N]), intrinsic WUE, PNUE and carbon stable isotope signatures ( delta super(13)C) were higher than the dry season, most likely a consequence of greater water availability within the substrate. Although differences in gas exchange could contribute to the invasiveness of Schinus into native pineland and disturbed upland areas, other aspects of its autoecology also play an important role.

AN - 73578730; 12931911 AB - Few studies have measured removal of pollutants by restored wetlands that receive highly variable inflows. We used automated flow-proportional sampling to monitor the removal of nutrients and suspended solids by a 1.3-ha restored wetland receiving unregulated inflows from a 14-ha agricultural watershed in Maryland, USA. Water entered the wetland mainly in brief pulses of runoff, which sometimes exceeded the 2500-m3 water holding capacity of the wetland. Half of the total water inflow occurred in only 24 days scattered throughout the two-year study. Measured annual water gains were within 5% of balancing water losses. Annual removal of nutrients differed greatly between the two years of the study. The most removal occurred in the first year, which included a three-month period of decreasing water level in the wetland. In that year, the wetland removed 59% of the total P, 38% of the total N, and 41% of the total organic C it received. However, in the second year, which lacked a drying period, there was no significant (p > 0.05) net removal of total N or P, although 30% of the total organic C input was removed. For the entire two-year period, the wetland removed 25% of the ammonium, 52% of the nitrate, and 34% of the organic C it received, but there was no significant net removal of total suspended solids (TSS) or other forms of N and P. Although the variability of inflow may have decreased the capacity of the wetland to remove materials, the wetland still reduced nonpoint-source pollution.

Many aspects of this structure are, however, still uncertain. This work provides a detailed petrographic assessment of a suite of representative drill core samples from the borehole Woodleigh 1 that penetrated uplifted basement rocks of the central part of this structure. Fundamental rock and mineral deformation data and high-precision chemical data, including results of PGE and oxygen isotopic analysis, are presented. The sampled interval displays likely impact produced macrodeformation in the form of fracturing and breccia veining at the microscopic scale. Contrary to earlier reports that these breccias represent pseudotachylite (friction-melt) or even shock/shear produced pseudotachylitic melt breccia cannot be confirmed due to pervasive post-impact alteration. Abundant planar deformation features (PDFs) in quartz, in addition to diaplectic glass and partial isotropization, are the main shock deformation effects observed, confirming that Woodleigh is of impact origin. Over the investigated depth interval, the statistics of quartz grains with a variable number of sets of PDFs does not change significantly, and the patterns of crystallographic orientations of PDFs in randomly selected quartz grains does not indicate a change in absolute shock pressure with depth wither. The value of oxygen isotopes for the recognition of meteoric contamination, as proposed by earlier Woodleigh workers, is critically assessed. Neither INA nor PGE analyses of our samples support the presence of a meteoric component within its basement section, as had been claimed in earlier work.
