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.

Annual adult survival was estimated to be 0.90 plus or minus 0.01 (SE). Variation in survival did not correspond to either local environmental fluctuation or more widespread disturbances associated with El Nino-Southern Oscillation events, and a time-invariant model of survival was best supported by our data. Absence of major oceanographic anomalies in the immediate vicinity of Johnston Atoll may contribute to relatively high and invariant survival in Brown Boobies.Original Abstract: Se estudio la supervivencia de individuos de Sula leucogasteren el atolon Johnston a lo largo de un periodo de 17 anos utilizando analisis de captura, marcaje y recaptura. La supervivencia anual estimada para los adultos fue de 0.90 plus or minus 0.01 (EE). La variacion en supervivencia no se asocio con fluctuaciones ambientales locales ni con disturbios mas generales asociados a El Nino, y nuestros datos apoyaron un modelo de supervivencia sin cambio en el tiempo. La ausencia de grandes anomalias oceanograficas en la vecindad inmediata del atolon Johnston podria contribuir a la supervivencia relativamente alta y constante en S. leucogaster.

On average, females visit 17 males in as many minutes before they choose a mate, and they preferentially visit males with hoods. When moving between burrows, fiddler crabs of both sexes sometimes approach and temporarily hide against objects on the surface. Hence, mate-searching females may approach hoods because they resemble (mimic) other objects that crabs approach to reduce their predation risk. We conducted two experiments to test this sensory trap hypothesis. First, we determined whether sexually receptive and nonreceptive female U.musica and nonreceptive female U.stenodactylus, a species that does not build structures, spontaneously approach hoods (replicas), stones, pieces of wood and shells. As predicted by the sensory trap hypothesis, both species, irrespective of sexual receptivity, approached these objects and neither preferred hoods. Second, to determine whether female U.musica show a preference for hoods when they search for a mate, we recorded the frequency with which females approached males with natural hoods, hood replicas, wood, stones and shells. Again as expected, females approached males with these different structures at the same rates. We conclude that hoods are effective mimics of objects that females approach for safety whether they are searching for a mate or not. Males benefit by using this sensory trap because hoods make them more attractive, and receptive females may benefit when they approach hoods because they reduce their mate-search risk.

A recent study has shown that free-ranging wedge-capped capuchin monkeys (C. olivaceus) in Venezuela self-anoint with a benzoquinone-secreting millipede, an activity by which they are hypothesized to appropriate chemical deterrents of mosquitoes. To evaluate the plausibility of this hypothesis, female yellow fever mosquitoes (Aedes aegypti) were presented with two millipede secretory compounds, 2-methyl-1,4-benzoquinone and 2-methoxy-3-methyl-1,4-benzoquinone, on nylon-reinforced silicone membranes placed over wells filled with human blood, a highly preferred food. Mosquitoes exhibited fewer landings, fed less frequently, and flew more frequently (a possible indication of repellency) in the presence of membranes treated with benzoquinones than with controls. These compounds also elicit self-anointing in captive male and female tufted (C. apella) and white-faced (C. capucinus) capuchin monkeys.

Location The Linganamakki region (State of Karnataka) of the Central Western Ghats of India. Method We selected thirty vegetation thickets ranging from 4 to 439 m super(2) in area in the vicinity of rain forest. The area of each small thicket was estimated as an oval using its maximum length and its maximum width. When the shape was irregular (mostly in large thickets) the limits of the thicket were mapped and the area calculated from the map. Plant species were identified, the number of individuals was estimated and their heights measured. Results There was a progression in the thickets from early to late successional species. Small thickets were characterized by ecotone species and savanna trees such as Catunaregam dumetorum. Savanna trees served as a nucleus for thicket formation. Colonizing species were mostly bird-dispersed. As succession proceeded in larger thickets, the proportion of evergreen, late-successional rain forest trees increased. The species composition of the large thickets differed depending on the species composition of reproductive adults in the nearby forested areas. The species within small thickets were also found in the large thickets. The nestedness in species composition suggested that species turnover was deterministic based on thicket size. Human disturbance (leaf and wood collection by the local populations) affected the species composition and the species-area relationship of thickets. Main conclusions Vegetation thickets are nodal centres for rain forest colonization within grasslands. They expand and replace savanna. Early successional bird-dispersed species established around savanna trees followed by late-successional rain forest trees dispersed from the nearby forest by birds. Restoration programmes that reproduce natural successional processes such as those observed in thickets will be more successful and less expensive than the methods currently being employed, where trees are individually planted in grassland. Wood harvesting is the only factor that prevents thicket growth and coalescence and hampers forest expansion.

Blooms of these organisms are attributed to two primary factors: natural processes such as circulation, upwelling relaxation, and river flow; and, anthropogenic loadings leading to eutrophication. Unfortunately, the latter is commonly assumed to be the primary cause of all blooms, which is not the case in many instances. Moreover, although it is generally acknowledged that occurrences of these phenomena are increasing throughout the world's oceans, the reasons for this apparent increase remain debated and include not only eutrophication but increased observation efforts in coastal zones of the world. There is a rapidly advancing monitoring effort resulting from the perception of increased impacts from these HABs, manifested as expanding routine coastal monitoring programs, rapid development and deployment of new detection methods for individual species, toxins, and toxicities, and expansion of coastal modeling activities towards observational forecasts of bloom landfall and eventually bloom prediction. Together, these many efforts will provide resource managers with the tools needed to develop effective strategies for the management and mitigation of HABs and their frequently devastating impacts on the coastal environment.

To measure the diet breadth of 4 Phestilla species on Guam, we offered the nudibranchs different corals in choice and no-choice feeding assays. Larval preferences were determined by measuring the percent metamorphosis in response to different coral species. We compared the specificity of larval metamorphosis to adult feeding preferences. Phestilla sibogae ate a range of Porites species (Poritidae) in the field and would not eat other coral genera in the laboratory no-choice assays. Metamorphosis was approximately 90% in response to 4 Porites spp. Phestilla minor was found on Porites lutea and Porites annae in the field. It preferred P. annae over Porites cylindrica and P. (Synaraea) rus during the choice and no-choice assays. The highest rates of metamorphosis (approx. 80%) were in response to P. lutea, P. annae, and P. cylindrica. Phestilla sp. 1 is morphologically similar to P. minor, but it eats different Porites species. It preferred P. (S.) rus, but would eat P. cylindrica during the no-choice assays. The highest rate of metamorphosis (approx. 80%) was in response to P. (S.) rus. Phestilla sp. 2 is distinct from the other Phestilla species studied, as it is a specialist on corals in the genus Goniopora (Poritidae). It preferred G. fruticosa and also ate G. minor and G. lobata during the feeding assays. The highest rates of metamorphosis (approx. 60%) were in response to G. fruticosa, G. minor, and G. lobata. This study documents a range of diet breadth among Phestilla species. Phestilla spp. larvae could distinguish between coral species within a host genus and showed a tendency to have high metamorphosis on their preferred hosts, but they also metamorphosed in response to non-food coral species.

Kyiv's immigrants have arrived from troubled countries in Africa, Latin America, & Asia, where their survival was based on skills in the "informal" sectors of society. They support themselves through small-scale trade, start-up manufacturing, & unofficial service provision while living in Soviet-built official housing. Troeshchyna, therefore, blends aspects of an overly planned Soviet city with those of a growing underplanned metropolis of the Third World. This study combines a sampling of the lives of the migrants, a look at the culture & development of a newly independent Ukraine, & an analysis of urban theory no longer based on a division between the formal & informal city. A survey of 250 international migrant families, interviews with 35 local officials & specialists who interact with them, & in-depth life histories of nearly two dozen migrants supplied the data for this study. 2 Figures.

Difference Fourier maps clearly showed H atoms positions near those O atoms at the midpoints of the tunnel edges. The O-H vectors point toward the Cl sites at the center of the tunnel, and weak hydrogen bonds likely form between the framework O atoms and Cl. The Cl position is near the center of a prism defined by the eight hydroxy1 H atoms. The Cl atoms fill approximately 2/3 of the tunnel sites, suggesting an ordering scheme in a given tunnel with every third tunnel site vacant. Such an arrangement allows the Cl anions to increase their separation distance along a tunnel by displacing away from one another toward their respective adjacent vacancies. The Fe-O octahedra in akaganeite are distorted with Fe-(O, OH) distances ranging from 1.94 to 2.13 Aa and show three longer and three shorter Fe-O distances; as expected the longer distances are associated with the OH-anions. Temperature-resolved synchrotron X-ray powder diffraction data and Rietveld refinements were used to investigate changes in the akaganeite structure and its transformation into hematite as it was heated from 26 to 800 degrees C. Rietveld refinements revealed surprising consistency in all unit-cell parameters between room temperature and approximately 225 degrees C, resulting in nearly zero thermal expansion of the akaganeite structure over a 200 degrees C interval. Above approximately 225 degrees C, the unit-cell volume gradually decreased, primarily in response to decreases in c and b, and an increase in the beta angle. The a parameter remained nearly constant until approximately 225 degrees C and increased thereafter. Akaganeite started to transform to hematite in the temperature range 290 to 310 degrees C with no evidence for maghemite as an intermediate phase.

Reliable age determinations are pivotal for assessing the patterns of human evolution and dispersal in this region. This paper reviews magnetostratigraphic studies of some early Pleistocene strata bearing hominin remains and/or artifact stone tools from northern to southern China. The quality and reliability of the paleomagnetic dates are also evaluated. New magnetostratigraphic results for the Xihoudu Paleolithic site in north-central China are also presented. Among the few hominin or Paleolithic sites in China from the early Pleistocene, five have been well investigated. Three of these are in northern China at Xiaochangliang, Donggutuo and Gongwangling; the remaining two in southern China at Longgupo and Yuanmou. Considerable progress has been made during the past three decades towards paleomagnetically dating these sites. Indeed, the age estimates at Xiaochangliang and Gongwangling have been widely accepted. Magnetostratigraphic consensus about the age of the Donggutuo site has also been reached. However, the age determination for the two sites in southern China is still contested. The integration of rock-magnetic stratigraphy with magnetic polarity stratigraphy has resulted in a determined age of 1.36 Ma for a stone tool-containing layer of lacustrine sediments at the Xiaochangliang site in the Nihewan Basin. Lithostratigraphic constraints have significantly contributed to determining the age of Lantian Homo erectus at Gongwangling, which occurred in a loess-paleosol sequence of the southern Loess Plateau. Its age, paleomagnetically derived, is about 1.15 Ma. These two paleomagnetic ages suggest an expansion and flourishing of human groups from northern to north-central China during the early Pleistocene. This suggestion has been reinforced by our new magnetostratigraphic age estimate of about 1.27 Ma for the Xihoudu site as will be presented in this paper. However, more work is needed for the age determinations of the hominin-bearing strata at the Longgupo and Yuanmou sites in southern China. Finally, we stress that it is necessary to combine biostratigraphy, lithostratigraphy and rock-magnetic stratigraphy with the traditional magnetic polarity stratigraphy in order to obtain reliable age determinations for strata bearing hominin remains or stone artifacts.

The central Motagua River valley is bordered by E-W-striking tectonic slices of serpentinite, some of which contain blocks of high pressure/low temperature (high P/T) eclogite, garnet amphibolite, and jadeitite. Recent exploration for commercial jadeitite (jade) has discovered considerable quantities of high P/T rocks in serpentinite bodies both further along and farther from the river. The southern bodies, south of the Motagua fault zone and adjacent to Chortis basement, also contain abundant eclogite, glaucophane eclogite, blueschist, jadeitite, and other high P/T rocks. The northern bodies, adjacent to Maya basement, include abundant jadeitite, albitite, and garnet amphibolite, but rare eclogite. Our initial studies find metasomatic signatures in most of the high-P/T rocks (e.g., phengite and quartz in veins, oscillatory zoning of jadeite and phengite, etc.). Mineralogical differences between jadeitites from the northern and southern bodies, and the different lithotectonic assemblages on the two sides of the Motagua fault zone suggest that either two high P/T events have occurred, or the two belts may be a single unit disrupted by strike slip duplexing.

Paradox of the late Turonian delta (super 18) O record at Deep Sea Drilling Project Site 511 AN - 51638322; 2006-012273 AB - Oxygen isotope data for upper Turonian planktonic foraminifera at Deep Sea Drilling Project Site 511 (Falkland Plateau) exhibit an excursion values coincident with the warmest tropical temperature estimates yet obtained for the open ocean. The lowest planktonic foraminifer delta (super 18) O values suggest that the upper ocean was as warm as 30-32 degrees C consistent with temperatures estimated from apparently coeval mollusc delta (super 18) O from nearby James Ross Island. Glassy textural preservation, a well-defined depth distribution in Site 511 planktonics, low sediment burial temperature, and lack of evidence of highly depleted pore waters argue against diagenesis as the cause of the very depleted planktonic values.

Despite a clear link between shipping and invasions, many aspects of this relationship remain unknown, limiting our ability to reduce invasions. A critical gap in knowledge exists for transfer dynamics of organisms in ships' ballast tanks and the efficacy of ballast water exchange (BWE), a treatment designed to interrupt this transfer. We test experimentally the effects of BWE, comparing temporal changes in concentration of organisms between experimental (exchanged) and control (unexchanged) tanks. BWE routinely removes > 90% of the original water. Zooplankton mortality in control tanks varies considerably across species, geographic regions, and voyage durations. BWE further reduces the concentration of zooplankton up to 95%, but efficacy varies among taxonomic groups and ship type. Microorganisms, including bacteria and virus-like particles, also exhibit a time-dependent decrease in control tanks. Exchange results in multiple changes for the microbial community, but effects on individual species are not yet resolved. We are testing relative effects of BWE and mortality associated with "salinity-shock", to learn whether the latter enhances interruption of species transfer to the Great Lakes.

To this end, we present a generalized approach for detecting potential ecological thresholds using assemblage-level attributes and a multimetric index (Index of Biological Integrity-IBI) as endpoints in response to numerical changes in water quality. To illustrate the approach, we used existing macroinvertebrate and surface-water total phosphorus (TP) datasets from an observed P gradient and a P-dosing experiment in wetlands of the south Florida coastal plain nutrient ecoregion. Ten assemblage attributes were identified as potential metrics using the observational data, and five were validated in the experiment. These five core metrics were subjected individually and as an aggregated Nutrient-IBI to nonparametric changepoint analysis (nCPA) to estimate cumulative probabilities of a threshold response to TP. Threshold responses were evident for all metrics and the IBI, and were repeatable through time. Results from the observed gradient indicated that a threshold was 50% probable between 12.6 and 19.4 mu g/L TP for individual metrics and 14.8 mu g/L TP for the IBI. Results from the P-dosing experiment revealed 50% probability of a response between 11.2 and 13.0 mu g/L TP for the metrics and 12.3 mu g/L TP for the IBI. Uncertainty analysis indicated a low (typically less than or equal to 5%) probability that an IBI threshold occurred at less than or equal to 10 mu g/L TP, while there was 95% certainty that the threshold was less than or equal to 17 mu g/L TP. The weight-of-evidence produced from these analyses implies that a TP concentration > 12-15 mu g/L is likely to cause degradation of macroinvertebrate assemblage structure and function, a reflection of biological integrity, in the study area. This finding may assist in the development of a numerical water-quality criterion for TP in this ecoregion, and illustrates the utility of bioassessment to environmental decision-making.

Recent advances have made it possible to use satellite imagery and computer-assisted spatial analysis technology along with fieldwork to determine estimates for these critical habitat needs for the endangered Golden-cheeked Warbler, Dendroica chrysoparia. Using these procedures, we estimate that the Ashe juniper-oak breeding habitat for this species covers 6430 km super(2) of central Texas, USA, whereas appropriate habitat in the known winter range covers 6750 km super(2) of the Middle American cordillera. When combined with information on warbler breeding and wintering ecology, these figures indicate that the amount of available winter habitat (pine-oak above 1219 m [4000'] in elevation) supports only a fraction (15%) of the population that could be supported by the amount of estimated available breeding habitat, suggesting that Golden-cheeked Warbler populations could be limited by winter habitat availability.

We examined bird communities associated with 11 natural and human-modified habitats in Panama and assessed the importance of those habitats for species of different vulnerability to disturbance. We calculated habitat importance scores using both relative habitat preferences and vulnerability scores for all species present. Species of moderate and high vulnerability were primarily those categorized as forest specialists or forest generalists. As expected, even species-rich nonforest habitats provided little conservation value for the most vulnerable species. However, shaded coffee plantations and gallery forest corridors were modified habitats with relatively high conservation value. Sugar cane fields and Caribbean pine plantations offered virtually no conservation value for birds. Our method of assessing the conservation importance of different habitats is useful because it considers the types of species present and the potential role of the habitat in the conservation of those species ( i.e., habitat preference ). This method of habitat evaluation could be tailored to other conservation contexts with any measure of species vulnerability desired.Original Abstract: El desarrollo de planes de conservacion efectivos para animales terrestres requerira de algunas evaluaciones para identificar aquellos habitats modificados por humanos y naturales que puedan soportar poblaciones de especies prioritarias. Examinamos las comunidades de aves asociadas con 11 habitats naturales y modificados por humanos en Panama y evaluamos la importancia de estos habitats para especies de diferente vulnerabilidad a la perturbacion. Se calcularon los valores de importancia del habitat usando tanto los valores de preferencia relativa de habitat como los de vulnerabilidad para todas las especies presentes. Las especies de vulnerabilidad moderada y alta fueron principalmente aquellas catalogadas como especialistas de bosque o generalistas de bosque. Segun lo esperado, aun los habitats no forestales ricos en especies proveyeron poco valor de conservacion para la mayoria de las especies. Sin embargo, las plantaciones de cafe con sombra y los corredores de galerias de bosque fueron habitats modificados con un valor relativamente alto de conservacion. Las plantaciones de cana de azucar y de pino del Caribe virtualmente no ofrecieron valor de conservacion para las aves. Nuestro metodo de evaluacion de la importancia para la conservacion de diferentes habitats es util puesto que considera los tipos de especie presentes y el papel potencial del habitat en la conservacion de estas especies ( es decir, habitat preferencial ). Este metodo de evaluacion de habitat puede ser adaptado a otros contextos de conservacion usando cualquier medida de vulnerabilidad de especies deseada.

Copepodids were sampled with a pump at five stations across the channel during a diel cycle. Diel changes of copepodid stages II - VI were marked by horizontal dispersal of Dioithona oculata, the dominant species, from swarms in the prop roots along the shore during the day to the edge of the prop root habitat at night. Migration of copepodids back to the prop roots appeared to be controlled endogenously because change from a night to a daytime age structure began before first light. Mean copepodid stage at subsurface depths in the channel and prop root edge decreased from 4.2 (with 6.0 = all adults) to 2.9 at predawn to 1.1 during day. The oceanic Oithona nana and O. simplex, and the coastal zone O. fonsecae were evenly distributed with depth and distance from shore during day and night, with avoidance of prop root shoreline during day. These species were much less abundant than Dioithona oculata in the prop roots, but of comparable or greater abundance in the channel. Coastal zone Acartia spinata exhibited evidence of swarming. Nauplii, sampled with a 25 mu m plankton net, were dominated by harpacticoid (50%) and cyclopoid (34%) nauplii, which generally were more abundant at 1m than at the surface and more abundant at night than the day. Lagrangian current measurements indicated velocities at ebb tide twice those of flood tide (1.9 vs. 0.8 cm s super(-1)) and a minimal residence time of 5 days, which could result in advection of D. oculata nauplii out of the Lair Channel before their recruitment into swarms as copepodid stage II. Previously reported maximum swimming speeds of swarming D. oculata copepodid stages (2.0 cm s super(-1)) and greater densities in prop roots and near the benthos may help copepodids avoid advection. The swarming behavior and diel horizontal migration (or dispersal) reported for D. oculata appears analogous to that of limnetic zooplankton, which may swarm among macrophytes along shorelines during the day to avoid visual predators and disperse or migrate away from the shoreline at night.

Extinction is Forever AN - 14675901; 10646008 AB - Considered extinct for 70 years, the Tasmanian tiger may re-emerge, cloned from DNA extracted from ancient specimens. This symbol of the island of Tasmania once dominated the food chain in its historic range in mainland Australia and north to New Guinea. They succumbed to competition from dingoes, lingering only on Tasmania, where there are no dingoes. Ultimately the tiger was hunted by settlers in the 1800s, and the last captive animal died in 1936. The cloning experiment, undertaken at the Australian Museum in Sydney, raises numerous ethical issues as well as research challenges.

He is lesser known for his environmentalism, but has used his position as a newspaper columnist to lambast developers, politicians, and investors responsible for the stripping of Florida's remaining wetlands. Raised in Ft. Lauderdale, Hiaasen grew up in the waters and mangrove swamps of the Keys, where he developed his love for nature. As a writer, Hiaasen has published over 1500 articles, 13 novels, and a book about the greed of the Walt Disney Company. Although he muckrakes over many issues, his particular concern is the loss of the Everglades and the moral imperative to save these vast wetlands.

Only 6 of the 17 African elephants born in captivity in the past eight years are still alive, an unsustainable rate of survival. It is no longer feasible or legal to replace elephants from the wild populations. Zookeepers are thus looking at all opportunities to improve captive breeding programs, from insemination to childbirth. Handling practices are also under scrutiny, with the traditional method of free contact often replaced with protected contact, which uses limited human contact and a physical barrier between keepers and elephants.

With few exceptions, previous studies have assumed one species of pollinator wasp per host fig species. Here we report genetic data demonstrating the coexistence of previously undetected cryptic fig wasp species in at least half of the host fig species surveyed. The substantial mitochondrial sequence differences (4.2-6.1%) imply old divergences ([approx]1.5-5.1 million years ago) among these species. Furthermore, some cryptic species pairs seem to be sister taxa, whereas others clearly are not, indicating both long-term coexistence on shared hosts and the colonization of novel fig species. These findings undermine the prevalent notion of strict one-to-one specificity between cospeciating figs and their pollinators, thereby challenging existing theory concerning the evolution and stability of mutualisms. Moreover, the incorporation of the genetic information significantly improves the fit of the observed sex ratios to predictions of local mate-competition theory, further strengthening support for sex allocation theory and the precision of adaptation.

The age of the Marie Byrd Land lithosphere is not known, as the only lower crustal samples (granulite and pyroxenite xenoliths) have proven resistant to conventional radiogenic dating methods. The oldest exposed magmatic rocks are Cambrian, and any Precambrian history for Marie Byrd Land, while speculated upon, is unknown. Here we present the first geochemical data for a peridotite xenolith suite from Marie Byrd Land, including Re-Os isotope measurements for 17 samples. The 17 spinel peridotites are from three volcanic centers: Mt Hampton and Mt Cumming, in the Executive Committee Range, and Mt Aldaz, in the USAS Escarpment. The xenoliths are residual lherzolites and harzburgites, ranging from fertile to depleted (e.g. 0.39-3.38 wt.% CaO) compositions. Re-Os isotopic systematics indicate a complex evolution for the Marie Byrd Land lithosphere. One sample records Re+Cu+ or -Os enrichment and two samples document localized Os enrichment, which is most likely related to supra-subduction zone processing, although enrichment due to plume interaction cannot be ruled out. Proterozoic lithosphere stabilization model ages of ca. 1.1 and >1.3 Ga are recorded in xenoliths from the Executive Committee Range. The Proterozoic ages are significantly older than outcropping mid-crustal rocks, marking Marie Byrd Land as a third circum-Pacific Phanerozoic mobile belt with preserved Proterozoic lithospheric mantle. The Mesoproterozoic Os model ages are consistent with Proterozoic Nd model ages in Marie Byrd Land granites and orthogneisses, and with a significant detrital zircon age component (ca. 1.0-1.2 Ga) in the thick Swanson Formation sediments that are exposed along the coast. The simplest interpretation of the available mantle and crustal age data is that the lower crust beneath Marie Byrd Land is also Proterozoic in age. Alternatively, if the mantle and lower crust in Marie Byrd Land are not temporally coupled, possible origins for the Proterozoic mantle include older lithosphere impinging from the adjacent East Antarctic craton, or lithospheric mantle that was incorporated into younger oceanic lithosphere during "messy" continental breakup (e.g. within an oceanic plateau) and subsequently accreted to the Antarctic margin.

Of five input parameters of the ZONMET model (chemical composition of the system expressed as the dust/gas [D/G] ratio, nebular pressure [P (sub tot) ], isolation degree [xi ], cooling rate (CR), and seed size), only two--the D/G ratio and the CR of the nebular source region of a zoned Fe,Ni grain--are important in determining the grain radius and Ni, Co, and Cr zoning profiles. We found no evidence for the supercooling during condensation of Fe,Ni metal that is predicted by the homogeneous nucleation theory. The model allows estimates to be made of physicochemical parameters in the CH chondrite nebular source regions. Modeling growth and simultaneous diffusional redistribution of Ni, Co, and Cr in the zoned metal grains of CH chondrites reveals that the condensation zoning profiles were substantially modified by diffusion while the grains were growing in the nebula. This means that previous estimates of the physicochemical conditions in the nebular source regions of CH and CB chondrites, based on measured zoning profiles of Ni, Co, Cr, and platinum group elements in Fe,Ni metal grains, need to be corrected. The two zoned metal grains in the PAT 91456 and NWA 470 CH chondrites studied so far require nebular source regions with different chemical compositions (D/G = 1 and D/G = 4, respectively) and thermal histories characterized by variable cooling rates (CR = 0.011+0.0022XDelta T K/h and CR = 0.05+0.0035XDelta T K/h, respectively). It appears that the metal grains of the CH chondrites were formed in multiple nebular source regions or in different events within the same source region as the CB chondrite metal grains were formed.

With pressure to extract timber from maturing forests, there is a need to identify the relative importance of forest types within the larger forest matrix. We examined small-mammal populations at 350 sample points across 157 km2 of forested habitat in the George Washington and Jefferson National Forests, Virginia, to determine landscape and habitat correlates of species abundance and richness. A total of 3,955 individuals representing 20 species were captured using live trap and pitfall sampling at each point during 1996 and 1997. Nine species were sufficiently common to examine their abundance relative to landscape and habitat features. We found species abundance and richness to be highest in mesic deciduous forest types, with the exception of Peromyscus leucopus . Soil moisture capacity and the proportion of mesic habitat within 100 m of the sample point were also important for several species. If mesic deciduous forest can be considered patches within a matrix of xeric forest, then the abundance of 4 species and species richness could be predicted based on the distance of the sample point to the nearest mesic patch and the abundance of 3 species inside mesic patches was related to patch size. At least 73% of mesic patches within this forest were 100 m. Our results indicate that mesic forest patches contain the bulk of the species richness for small mammals in the Southern Appalachian ecotype. Designing timber harvests that minimize use of mesic deciduous forest type and that does not decrease patch numbers would achieve the largest benefits to small mammals within the region.

First tests had significantly greater statistical power and reported more significant results journals, taxa, and the type of statistical test used. On average, statistical power was 13-16% to detect a small effect and 40-47% to detect a medium effect. This is far lower than the general recommendation of a power of 80%. By this criterion, only 2-3%, 13-21%, and 37-50% of the tests examined had the requisite power to detect a small, medium, or large effect, respectively. Neither p values nor statistical power varied significantly across the 10 journals or 11 taxa. However, mean p values of first and last tests were significantly correlated across journals, with a similar trend for mean power. There is therefore some evidence that power and p values are repeatable among journals. Mean p values or power of first and last tests were, however, uncorrelated across taxa. Finally, there was a significant correlation between power and reported p value for both first and last tests. If true effect sizes are unrelated to study sample sizes, the average true effect size must be nonzero for this pattern to emerge. This suggests that failure to observe significant relationships is partly owing to small sample sizes, as power increases with sample size.

Sediment deposition is one process that affects their ability to maintain surface elevations relative to adjacent rivers. Sediment dynamics in salt marshes have been studied extensively, but little is known about the factors that control sediment deposition rates in tidal freshwater wetlands. We examined geomorphic, hydrological, and biotic factors that may influence sedimentation in two tidal freshwater wetlands that fell at opposite ends of the riverine-estuarine continuum. Our data demonstrate that sediment dynamics are highly variable among tidal freshwater wetlands, and are influenced by the location of the wetland on the continuum. Sediment deposition was up to 10 times higher during the growing season at the downstream site than the upstream site. Plant density and height were highly correlated with sediment deposition rates at the downstream site (r0.92, p less than or equal to 0.009) but not at the upstream site. Elevation, flood depth, and flood duration were correlated with deposition rates only when each site/season combination was considered separately. River suspended sediment and surficial floodwater suspended sediment concentrations were significantly higher at the downstream site (p=0.02 and p=0.04, respectively). These data suggest that vegetation is important in determining sediment deposition rates when river suspended sediment is not limiting, which is not always the case. Longer flood duration increased sediment deposition, but was of secondary importance. Land use and proximity to the turbidity maximum (near the forward extent of the salt water intrusion) appear to be critically important in determining river suspended sediment availability in the tidal freshwater zone of the Mattaponi River, VA.

Foraging experiments under seminatural conditions were designed to control for the spatiotemporal distribution of resources at one or two preying sites. Using both single- and multi-event past experience, individual foragers of E. ruidum and (although less significantly) E. tuberculatum made directional and temporal adjustments to their behavior in response to previous differential foraging success. In spite of considerable individual variation in foraging efficiency, it is hypothesized that the observed differences in cognitive abilities can be invoked to explain ecological differences among both species.

Cuba has gained a reputation in the region for its biological resources, which include coral reefs, rain forest, and tropical wetlands, all supporting endemic and rare species. While development has stripped much of the Caribbean of these resources, Cuba's biological riches have been spared through planning by Castro's regime as well as commercial repression. Although mammals are rare, other animal forms are well-represented, and plant diversity is high. As with other islands, both dwarf and giant species flourish.

The observatory includes mathematically constructed spaces that orient toward episodic astronomical events, as well as those that capture a unique perspective on the daily rise and fall of the sun. The resulting sculpture crosses the lines between art and science, operating through human perception. During his career, Turrell has worked in the medium of light, mixing and mastering visual perceptions to create beauty and illusion.

We estimated NPS discharges with linear models fit to measurements of weekly flow and 10 material concentrations from 22 study watersheds. The independent variables were the proportions of cropland and developed land, physiographic province (Coastal Plain or Piedmont), and time (week). All but one of the NPS models explained between 62% and 83% of the variability among concentration or flow measurements. Geographic factors (land cover and physiographic province) accounted for the explained variability in largely dissolved material concentrations (nitrate [NO sub(3)], silicate [Si], and total nitrogen [TN]), but the explained variability in flow and particulates (sediment and forms of phosphorus) was more strongly related to temporal variability or its interactions with land cover and province. Average concentrations of all materials increased with cropland proportion and also with developed land (except Si), but changes in cropland produced larger concentration shifts than equivalent changes in developed land proportion. Among land cover transitions, conversions between cropland and forest-grassland cause the greatest changes in material discharges, cropland and developed land conversions are intermediate, and developed land and forest-grassland conversions have the weakest effects. Changing land cover has stronger effects on NO sub(3) and TN in the Piedmont than in the coastal Plain, but for all other materials, the effects of land-use change are greater in the Coastal Plain. We predicted the changes in nutrient load to the estuary under several alternate land cover configurations, including a state planning scenario that extrapolates current patterns of population growth and land development to the year 2020. In that scenario, declines in NPS discharges from reducing cropland are balanced by NPS discharge increases from developing an area almost six times larger than the lost cropland. When PS discharges are included, there are net increases in total water, total phosphorus, and TN discharges.

The slumps and hiatus occur within a sequence dominated by pelagic chalk. The (super 87) Sr/ (super 86) Sr measurements show a general increase through the Maastrichtian at each site, but suggest chronostratigraphic gaps on the order of 10 (super 6) yr across the slumps. Some of the slumps have burrowed upper surfaces and are composed of material that is older and coarser grained than the bounding chalks. Pelagic deposition punctuated by gravity flows easily explains the Maastrichtian record on Blake Nose, whereas an impact-based explanation for slumping is difficult to reconcile with sedimentological and geochemical observations.

This association is well known, but the link between caldera formation and the origins of the deposits remains poorly understood. Here we show that the size and location of a VMS deposit within a submarine caldera may be determined by how and when the caldera formed. These spatial-temporal conditions control development of the hydrothermal system associated with the VMS deposit. We propose that caldera opening along outward-dipping faults promotes magma degassing, seawater influx, and high-temperature leaching, resulting in a metal-rich hydrothermal fluid. These outward-dipping faults are considered to provide critical pathways for ore-forming fluids responsible for some caldera-hosted VMS deposits and may also be fundamentally important for the formation of many other caldera-hosted ore deposit types.

From caldera-lake beds exposed at Laguna del Hunco in Patagonia, Argentina, paleolatitude approximately 47 degrees S, we report 102 leaf species. Radioisotopic and paleomagnetic analyses indicate that the flora was deposited 52 million years ago, the time of the early Eocene climatic optimum, when tropical plant taxa and warm, equable climates reached middle latitudes of both hemispheres. Adjusted for sample size, observed richness exceeds that of any other Eocene leaf flora, supporting an ancient history of high plant diversity in warm areas of South America.

These rocks unconformably overlie Permian rocks of the Golconda Allochthon and are believed to have been deposited on the allochthon after its emplacement on the continental margin in the Late Permian or Early Triassic. The fauna thus provides a rare biogeographical calibration point along the cratonal margin for judging the latitudinal affinities of faunas of comparable age on displaced terranes. Previous studies of colonial corals, hydrozoans, and involutinid foraminiferans in the Ladinian part of this section have emphasized West Tethyan affinities. An ongoing systematic study of the bivalves is revealing a very different paleobiogeographic picture. Twenty bivalve species exhibit remarkable endemism at both the species (60%) and genus (29%) levels, and several species provide clear biogeographic ties with the northern and especially eastern Pacific realms. One example is a new pectinid genus and species that occurs in association with "Tethyan" colonial corals but has congeners only in known cratonal rocks of NE British Columbia of Ladinian and Carnian age (the Mahaffy Cliffs and Lima? poyana faunas of McLearn). Another example higher in the section is a distinctive gigantic bakevelliid strongly resembling a species in the Tethyan Sephardic Province (S. Spain, Algeria, Jordan). The Nevada form occurs in association with three ammonoid species that are the same as or comparable to Canadian species that characterize the Meginae to Sutherlandi zones of the Ladinian as well as with species of Protrachyceras resembling Ladinian Tethyan species. Morphological details of the bivalve, however, indicate a sister-group relationship with the Sephardic form, not conspecificity, and suggest descent from an older, probably Anisian, common ancestor. Past assessments of Tethyan affinities of this fauna may be biased by including only slowly evolving taxa. The more rapidly evolving bivalves, in contrast, are more sensitive indicators of biogeographic affinity and, with the ammonoids, demonstrate that the Easter Pacific Realm was an important center of speciation in the Ladinian.

The material from the Zaysan Basin is indistinguishable from the holotypes of Isectolophus bogdulensis Reshetov from Mongolia and Homogalax reliquius Qi from China. These two species are junior subjective synonyms of I. latidens. The presence of I. latidens, known also from Bridgerian strata of North America, in Asian deposits of Arshantan age provides further support for a correlation between the Arshantan and the Bridgerian landmammal "ages."

The construction of large stratovolcanoes and other minor volcanoes formed the nearly N-S-trending Cofre de Perote-Citlaltepetl volcanic chain, which represents an important topographic barrier that separates the Central High-Plain (2,500 masl) from the Gulf Coastal Plain (1,300 masl). The abrupt relief between these physiographic provinces has favored unstable conditions with the subsequent catastrophic sedimentation derived mainly from the gravitational collapse of the large volcanic edifices. Large amounts of volcanic sediments have been produced in the last 0.5 Ma, and were widely spread preferentially towards the eastern flank of the volcanic range. The continuous sedimentation formed a relatively flat topography with a well-developed drainage and deep barrancas formed by thick volcaniclastic deposits that characterizes the Coastal Plain. Complex processes of sedimentation occurred during the transportation of the volcaniclastics producing lateral transformations from primary voluminous debris avalanche and lahar deposits to debris flows, hypoconcentrated and runout deposits. Most of the sedimentation is attributed to major catastrophic collapse-related events that have been identified in the stratigraphic record and are related to the major volcanic complexes such as Citlaltepetl, Las Cumbres, and Cofre de Perote volcanoes and perhaps also La Gloria volcanic complex. At least three major catastrophic events are associated with Citlaltepetl volcano, one of the largest deposits was formed from Las Cumbres volcanic complex, and two more from Cofre de Perote volcano. Also, a debris flow deposit was derived from the middle part of the volcanic range as a result of a strong earthquake in 1920. No direct evidence of magmatic activity has been found in relation to the origin of the catastrophic sedimentation. Therefore, other triggering factors such as: frequent seismic activity and high rain precipitation may be considered as well. Unstable conditions such as very intense hydrothermal alteration, abrupt topography and intense fracturing of the volcanic edifices have been strong in the past. Recurrence of new catastrophic events are very likely in the near future as those conditions are still affecting the volcanic range.

Prior to the late 20th century, centennial-scale changes in species dominance were influenced by climatic and hydrological factors that primarily affected salinity and at times led to oxygen depletion. Decadal-scale droughts also occurred resulting in higher salinities and migration of ostracode species from the deep channel (Loxoconcha sp., Cytheromorpha newportensis) into shallower water along the flanks of the bay. During the 19th century the abundance of Leptocythere nikraveshae and Perissocytheridea brachyforma suggest increased turbidity and decreased salinity. Unprecedented changes in benthic ostracodes at the Patuxent mouth and in the deep channel of the bay occurred after the 1960s when Cytheromorpha curta became the dominant species, reflecting seasonal anoxia. The change in benthic assemblages coincided with the appearance of deformities in foraminifers. A combination of increased nitrate loading due to greater fertilizer use and increased freshwater flow explains this shift. A review of the geochemical and paleoecological evidence for dissolved oxygen indicates that seasonal oxygen depletion in the main channel of Chesapeake Bay varies over centennial and decadal timescales. Prior to 1700 AD, a relatively wet climate and high freshwater runoff led to oxygen depletion but rarely anoxia. Between 1700 and 1900, progressive eutrophication occurred related to land clearance and increased sedimentation, but this was superimposed on the oscillatory pattern of oxygen depletion most likely driven by climatological and hydrological factors. It also seems probable that the four- to five-fold increase in sedimentation due to agricultural and timber activity could have contributed to an increased natural nutrient load, likely fueling the early periods (1700-1900) of hypoxia prior to widespread fertilizer use. Twentieth-century anoxia worsened in the late 1930s-1940s and again around 1970, reaching unprecedented levels in the past few decades. Decadal and interannual variability in oxygen depletion even in the 20th century is still strongly influenced by climatic processes influencing precipitation and freshwater runoff.

The present study was aimed at identifying the ecophysiological traits specific to S. olneyi that drive these CO sub(2)-assimilation patterns under ambient and elevated CO sub(2) conditions. The net ecosystem exchange (NEE) of CO sub(2) between S. olneyi communities and the atmosphere was measured in open-top chambers. We developed a new mechanistic model for S. olneyi communities based on published ecophysiological data and additional measurements of photosynthetic parameters. Our NEE measurements confirmed that S. olneyi communities have a high rate of summertime CO sub(2) assimilation, with noontime peaks reaching 40 mu mol CO sub(2) m super(-2) ground s super(-1) on productive summer days, and that elevated CO sub(2) increased S. olneyi CO sub(2) assimilation by c. 35-40%. Using S. olneyi-specific ecophysiological parameters, comparison with measured NEE showed that the model accurately simulated these high rates of CO sub(2) uptake under ambient or elevated CO sub(2). The model pointed to the Rubisco capacity of Scirpus leaves associated with their high total nitrogen content as the primary explanation for the high rates of CO sub(2) assimilation, and indicated that the vertical-leaf canopy structure of S. olneyi had comparatively little influence on CO sub(2) assimilation.

In six early-spawning species, gamete bundles appear on the surface of the colony ("setting") about 1 h before sunset, whereas setting occurs about 1 h after sunset in the more common late mass spawners. These early spawners are divided further into two sub-groups: three species that release their gametes within 1 h after setting and three that release their gametes 1.5-2 h after setting. DNA phylogenetic analyses show that each of these groups forms an independent genetic clade. These genetic relationships suggest that different spawning times form the basis of reproductive isolation among these broadcast-spawning corals. Late spawning appears to be the ancestral state, and the shift of spawning to earlier times may have played a role in the speciation process in these sympatric species.

Models indicate that AM fungal communities could maintain plant diversity in forests if functionally different communities are spatially separated. In this study we assess the spatial and temporal distribution of the AM fungal community in a wet tropical rainforest in Costa Rica. We test whether distinct fungal communities correlate with variation in tree life history characteristics, with host tree species, and the relative importance of soil type, seasonality and rainfall. Host tree species differ in their associated AM fungal communities, but differences in the AM community between hosts could not be generalized over life history groupings of hosts. Changes in the relative abundance of a few common AM fungal species were the cause of differences in AM fungal communities for different host tree species instead of differences in the presence and absence of AM fungal species. Thus, AM fungal communities are spatially distinguishable in the forest, even though all species are widespread. Soil fertility ranging between 5 and 9 Mg/ha phosphorus did not affect composition of AM fungal communities, although sporulation was more abundant in lower fertility soils. Sampling soils over seasons revealed that some AM fungal species sporulate profusely in the dry season compared to the rainy season. On one host tree species sampled at two sites with vastly different rainfall, relative abundance of spores fromAcaulospora was lower and that ofGlomus was relatively higher at the site with lower and more seasonal rainfall.

Twenty-seven fig species (264 individuals, c. 120 ha) colonized a diversity of host taxa (35 families), but densities were very low and only 1.77% of trees> 30 cm d.b.h. were occupied. There were no significant associations with host taxa or host-bark roughness but among 11 common species ( greater than or equal to 9 individuals) the distributions of all other parameters (host-d.b.h., height and position of colonization, crown illumination, soil-texture and slope-angle) were significantly different, and we identified five fig guilds. The guilds corresponded to canopy strata, and appeared to reflect the establishment microsite requirements of different species. A fundamental trade-off within the hemi-epiphytic habit was revealed: Species colonizing larger hosts were rarer, because of lower host densities and more specific microsite requirements, but had better light environments and attained a larger maximum size. The single strangler species appeared to escape many of these constraints, and an important source of mortality caused by host-toppling, indicating the advantages of this strategy.

We also compared nonpoint source (NPS) discharges from Piedmont and Coastal Plain regions and from agricultural and developed lands. Using continuous automated-sampling, we measured discharges of water, nitrogen, phosphorus, organic carbon (C), and suspended solids from a total of 23 watersheds selected to represent various proportions of developed land and cropland in the Patuxent River basin and the neighboring Rhode River basin. The sampling period spanned two years that differed in annual precipitation by a factor of 1.7. Water discharge from the watershed to the Patuxent River estuary was 3.4 times higher in the wet year than in the dry year. Annual water discharges from the study watersheds increased as the proportion of developed land increased. As the proportion of cropland increased, there were increases in the annual flow-weighted mean concentrations of nitrate (NO sub(3) super(-)), total nitrogen (TN), dissolved silicate (Si), total phosphate (TPO sub(4) super(3-)), total organic phosphorus (TOP), total P (TP), and total suspended solids (TSS) in NPS discharges. The effect of cropland on the concentrations of NO sub(3) super(-) and TN was stronger for Piedmont watersheds than for Coastal Plain watersheds. As the proportion of developed land increased, there were increases in annual mean concentrations of NO sub(3) super(-), total ammonium (TNH sub(4) super(+)), total organic N (TON), TN, total organic C (TOC), TPO sub(4) super(3-), TOP, TP, and TSS and decreases in concentrations of Si. Annual mean concentrations of TON, TOC, forms of P, and TSS were highest in the wet year. Annual mean concentrations of NO sub(3) super(-), TNH sub(4) super(+), TN, and Si did not differ significantly between years. We directly measured NPS discharges from about half of the Patuxent River basin and estimated discharges from the other half of the basin using statistical models that related annual water flow and material concentrations to land cover and physiographic province. We compared NPS discharges to public data on point source (PS) discharges. We estimated direct atmospheric deposition of forms of N, P, and organic C to the Patuxent River estuary based on analysis of bulk deposition near the Rhode River. During the wet year, most of the total terrestrial and atmospheric inputs of forms of N and P came from NPS discharges. During the dry year, 53% of the TNH sub(4) super(+) input was from atmospheric deposition and 58% of the NO sub(3) super(-) input was from PS discharges; NPS and PS discharges were about equally important in the total inputs of TN and TPO sub(4) super(3-). During the entire 2-yr period, the Coastal Plain portion of the Patuxent basin delivered about 80% of the NPS water discharges to the estuary and delivered similar proportions of the NPS TNH sub(4) super(+), TN, TOP, and TSS. The Coastal Plain delivered greater proportions of the NPS TON, TOC, Si, and TP (89%, 90%, 93%, and 95%, respectively) than of water, and supplied nearly all of the NPS TPO sub(4) super(3-) (99%). The Piedmont delivered 33% of the NPS NO sub(3) super(-) while delivering only 20% of the NPS water to the estuary. We used statistical models to infer the percentages of NPS discharges supplied by croplands, developed lands, and other lands. Although cropland covers only 10% of the Patuxent River basin, it was the most important source of most materials in NPS discharge, supplying about 84% of the total NPS discharge of NO sub(3) super(-); about three quarters of the TPO sub(4) super(3-), TOP, TP, and TSS; and about half of the TNH sub(4) super(+) and TN. Compared to developed land, cropland supplied a significantly higher percentage of the NPS discharges of NO sub(3) super(-), TN, TPO sub(4) super(3-), TOP, TP, and TSS, despite the fact developed land covered 12% of the basin.

The harsh environment is less of a threat, however, than residues of chemical toxins which have accumulated in this environment. Polychlorinated biphenyls (PCBs), in particular, have bioaccumulated in the bears, which are captured, sampled, and tagged by researchers. The bears have been showing signs of contamination since the 1990s, with PCB levels noted at 12 times the levels of their Alaskan counterparts. The PCBs are transported to the Arctic through prevailing winds, where they are then trapped in snow and ice, and eventually accumulate up the food chain. High concentrations affect reproductive capabilities, as well as cub survival.

Two new formations, the Punta Alegre Formation (lower Miocene, Aquitanian to Burdigalian) and the Valiente Formation (middle Miocene, Langhian to Serravallian), are here named and formally described. The Punta Alegre Formation contains a diagnostic microfauna of benthic and planktic foraminifera and calcareous nannofossils that indicate deposition in a 2000-m-deep pre-isthmian neotropical ocean from as old as 21.5-18.3 Ma. Its lithology varies from silty mudstone to muddy foraminiferal ooze with rare thin microturbidite layers near the top. The Valiente Formation, which ranges in age from 16.4 to ca. 12.0 Ma, lies with slight angular unconformity on the Punta Alegre Formation and consists of five lithofacies: (1) columnar basalt and flow breccia, (2) pyroclastic deposits, (3) coarse-grained volcaniclastic deposits, (4) coral-reef limestone with diverse large coral colonies, and (5) marine debris-flow deposits and microturbidites. These lithofacies are interpreted to indicate that after ca. 16 Ma a volcanic arc developed in the region of Bocas del Toro and that by ca. 12 Ma an extensively emergent archipelago of volcanic islands had formed. (super 39) Ar/ (super 40) Ar dating of basalt flows associated with the fossiliferous sedimentary rocks in the upper part of the Valiente Formation strongly confirms the ages derived from planktic foraminifera and nannofossils. Paleobathymetric analysis of the two new formations in the Valiente Peninsula and Popa Island, in the Bocas del Toro archipelago, shows a general shallowing from lower- through upper-bathyal to upper-neritic and emergent laharic and fluviatile deposits from ca. 19 to 12 Ma. The overlying nonconformable Bocas del Toro Group contains a lower transgressive sequence ranging from basal nearshore sandstone to upper-bathyal mudstone (ca. 8.1-5.3 Ma) and an upper regressive sequence (5.3-3.5 Ma). A similar paleobathymetric pattern is observed from the Gatun to Chagres Formations (12-6 Ma) in the Panama Canal Basin area and in the Uscari, Rio Banana, Quebrada Chocolate, and Moin Formations (8-1.7 Ma) in the southern Limon Basin of Costa Rica.

The Camargo volcanic field lies in the northern part of the province, midway between the Sierra Madre Occidental and Trans-Pecos Texas. It is formed by Pliocene-Pleistocene (4.7-0.09 Ma) intraplate mafic alkalic volcanic rocks, some of which contain peridotite, pyroxenite, and granulite xenoliths. The volcanic field covers approximately 3000 km (super 2) and has an estimated volume of approximately 120 km (super 3) erupted from >300 recognized vents. Twenty-six new (super 40) Ar/ (super 39) Ar age determinations for the Camargo volcanic field and its environs show that volcanic activity began in the southwest part of the field and shifted toward the northeast at approximately 15 mm/yr. The average magmatic eruption rate during growth of the field was approximately 0.026 km (super 3) /k.y. The Camargo volcanic field lies within an accommodation zone with west-dipping faults and east-tilted blocks to the north and east-dipping faults and west-tilted blocks to the south. These faults are expressed in the volcanic field by a N30 degrees W-trending graben with scarps up to approximately 100 m high through its central part. Volcanism and faulting were at least in part coeval, and younger volcanic products commonly drape fault scarps that cut earlier lavas. Normal faulting is bracketed between 4.7 and 2.1 Ma and may have also migrated northeastward. Estimated vertical slip rates on four Pliocene faults range from 0.03 mm/yr, a likely long-term rate, to 1.67 mm/yr, interpreted as a short-term rate operative during periods of active faulting. Northwest-striking normal faults that cut alluvial-fan deposits and Pleistocene lavas in the northern Camargo volcanic field and geomorphic evidence for recent uplift to the south of the volcanic field suggest that the region is still extending.

The veins cut the Fire Lake mafic meta-volcanic rocks, occurring within 600 m of an outcrop of Cretaceous S-type granite. Field work and vein petrography are consistent with a polythermal origin for the veins. The primary vein mineralogy is quartz and tourmaline with variable sized alteration haloes consisting of tourmaline, quartz, muscovite, chlorite and emerald. The veins weather a buff brown colour due to jarosite, scheelite and minor lepidocrocite, which were precipitated during the waning stages of vein formation. Microthermometic studies of primary fluid inclusions within emerald growth zones are consistent with emerald precipitation from H (sub 2) O-CO (sub 2) -CH (sub 4) (+ or -N (sub 2) + or -H (sub 2) S) bearing saline brines. The estimated fluid composition is approximately 0.9391 mol% H (sub 2) O, 0.0473 mol% CO (sub 2) , 0.0077 mol% CH (sub 4) and 0.0059 mol% NaCl ( approximately 2 wt.% NaCl eq.). Fluid inclusion and stable isotope studies are consistent with vein formation in the temperature range 365-498 degrees C, with corresponding pressures along fluid inclusion isochore paths ranging from 700 to 2250 bars. These data correlate with a very slow uplift rate for the region of 0.02-0.07 mm/year. Emerald deposits are generally formed when geological conditions bring together Cr (+ or -V) and Be. Cr and V are presumed to have been derived locally from the mafic and ultramafic rocks during hydrothermal alteration. The Be is most likely derived from the nearby Cretaceous granite intrusion.

Our study records a higher proportion of White Nile sediment transported during the annual floods at ca. 6100 cal yr B.P. than towards 4200 cal yr B.P., at which time suspended sediment from the Blue Nile formed a significantly larger fraction of the total load. This resulted from a decrease in vegetative cover and an increase in erosion rate accompanying the marked decline in rainfall. These new geoscience data indicate major changes in annual flooding and baseflow of the river Nile, marked short-term paleoclimatic-related events that may in part have led to the collapse of the Old Kingdom.

In the Eastern Hemisphere the dichotomy boundary is marked by a prominent scarp and extensional and compressional tectonic features. Topographic data across the boundary returned from the Mars Global Surveyor indicate lithospheric flexure of the southern highlands. The topography of the boundary can be fit by a universal lithospheric deflection profile that corresponds to an elastic thickness of approximately 31-36 km. Flexure of the southern highlands may be due to late Noachian-early Hesperian vertical loading of the northern lowlands. Fracturing and normal faulting along the boundary may be in response to bending stresses, while thrust faulting may result from a combination of stresses due to flexure, erosion, and global contraction.

Sperm must be stored in seminal receptacles until eggs are produced and fertilized months to years after mating. Further, intense fishing pressure impacts male abundance, male size and population sex ratio, which affect ejaculate quantity. We measured temporal variation in seminal receptacle contents in relation to brood production for two stocks differing in both fishing pressure on males and latitudinal effects on reproductive season: Chesapeake Bay, Maryland and Virginia, experienced intensive fishing and relatively short reproductive season; and the Indian River Lagoon, Florida, experienced lower exploitation and longer reproductive season. Nearly all (>98%) females were mated, and mating prevalence did not vary among sites during 1996. Seminal receptacle weight declined markedly for 2 mo following mating as seminal fluid disappeared to leave only spermatophores for long-term storage, which suggests that seminal fluid serves as a short-term sperm plug. Seminal receptacle weight in upper Chesapeake Bay declined by 31% from 1992-1999, indicating that females received smaller ejaculates. In 1996, seminal receptacle contents were highest (3.75 g wet wt, 2.3 x 10 super(3) mu g DNA, 1.2 x 10 super(9) sperm) in Florida, but were significantly lower by: 25% for weight and 50% for sperm number at the upper Chesapeake Bay site; and 30% for weight and 65% for sperm number at lower Chesapeake Bay sites. Generally, females receive 2-3 x 10 super(3) spermatophores and 10 super(8)-10 super(9) sperm cells for a full ejaculate, whereas females produce ca. 3 x 10 super(6) eggs per brood. Chesapeake Bay females appear to live about 3.5 yr, producing 1-3 broods (up to 9 x 10 super(6) eggs) per year and up to 6-7 broods (2.1 x 10 super(7) eggs) per lifetime. In contrast, Florida crabs produced up to 6-7 broods (2.1 x 10 super(7) eggs) per year, and up to 18 broods (5.4 x 10 super(7) eggs) per lifetime. In Florida, last broods produced by lab-held females were often infertile, indicating that females became sperm limited at the end of their lifetime. Experiments showed that male mating history affected female reproductive success, with females mated late in a sequence having only one third the brood hatching success of females mated early in the sequence. Sperm:egg ratios were estimated at 100:1 to 400:1 for the first brood but only about 20:1 or 30:1 for maximum lifetime broods over 2 seasons, suggesting that about 67 x 10 super(6) sperm are used per brood of 3 x 10 super(6) eggs. A model of brood production and sperm depletion in blue crabs indicates that sperm limitation may be common in Florida as females age, and in Chesapeake Bay as a result of fishery-induced reductions in initial quantities of sperm transferred at mating.

Ecological factors included geographical distributions of species, habitat preferences, interspecific interactions, reproductive ecology, and tolerance to bleaching. Genetic differences were based on the electrophoretic analysis of ten allozyme loci. Morphological analyses consisted of tissue coloration, colony morphology, and measurements and counts of ten macro- and micro-skeletal characters. P. varians, present on reefs or in coral communities, is the most widely distributed and shows considerable morphological variation. P. chiriquiensis, a recently described species, encrusts basalt rock and has little morphological variation. P. frondifera is a reef dweller with a compact foliose morphology. Tissue coloration varies from light to dark brown in P. varians, from pink to brown in P. frondifera, and from brick red to brown or silvery in Pavona chiriquiensis. Also, the white to silvery polyp mouths of the latter species are a diagnostic feature that allows an easy identification in the field. Aggressive dominance during short-term interspecific interactions were as follows: Pavona chiriquiensis>P. varians>P. frondifera. P. chiriquiensis and P. varians showed contrasting responses to sea warming during the 1997-1998 El Nino Southern Oscillation. Whereas entire P. chiriquiensis bleached and died within 4 weeks of exposure to 30-31 degree C, colonies of P. varians did so only on their upper surfaces. The response of P. frondifera to elevated temperatures was not observed because it is mainly present in the Gulf of Panama where coral bleaching was absent in 1997-1998. The genetic data indicated that P. chiriquiensis differed strongly from both P. varians and P. frondifera, with Nei's unbiased genetic distances of 0.434 and 0.379, respectively. A fixed difference between P. varians and P. frondifera, and P. chiriquiensis exists at the triose phosphate isomerase (TPI-2) locus. A nearly fixed difference between P. chiriquiensis and P. frondifera and between P. chiriquiensis and P. varians was found at the hexokinase (HK) locus. P. varians differed slightly from P. frondifera with Nei's unbiased genetic distance of 0.068. No fixed difference was found between P. varians and P. frondifera. There were strong differences between P. chiriquiensis and P. varians in spawning times and gamete characteristics. Spawning in P. varians and P. chiriquiensis is 12 h out of phase. Also, eggs of the former species are white to beige and positively buoyant whereas those of the latter species are dark green and neutrally to negatively buoyant. No reproductive data are yet available for P. frondifera. Calicular diameters are significantly greater in P. chiriquiensis than in the other two species. In contrast, corallum thickness is greater in P. varians and P. frondifera than in P. chiriquiensis. Canonical discriminant function analysis readily separated the three species.

We aimed to test whether nutrient additions differentially altered photosynthetic performance and resource utilization in these two species. In control trees, photosynthetic rates were higher in L. racemosa than A. germinans. However, leaf nitrogen concentrations were higher in A. germinans than L. racemosa. Avicennia germinans responded to fertilization with nitrogen by increasing leaf nitrogen concentrations and rates of photosynthesis such that they were equivalent to photosynthesis in L. racemosa. Laguncularia racemosa did not show a response to nitrogen additions. Neither species showed strong responses to phosphorus fertilization. Avicennia germinans had high photosynthetic water-use efficiency (photosynthesis/transpiration), but low photosynthetic nitrogen-use efficiency (photosynthesis/leaf nitrogen). In contrast, L. racemosa had comparatively low photosynthetic water use efficiency and high photosynthetic nitrogen use efficiency. Leaf level characteristics lead us to hypothesize that coexistence of A. germinans and L. racemosa should occur where nitrogen levels are low and salinity is moderate, or at least moderate for some period of the year.

Seven pollinators (hummingbirds) and four robbers (1 hummingbird and 3 perching birds) comprised the avian nectarivorous guild visiting H. patens during March 1997. In addition, two florivorous birds were observed visiting H. patens during the study. Pollinators accounted for 85.6 percent of the visits, robbers for 12.4 percent, and florivores for 2 percent of the visits. Visitation by pollinators and robbers was greatest when floral nectar was highest. No aggressive interactions between pollinators and robbers were observed during the study. Pollinators differed in their ability to carry and deposit pollen on the stigma. Territorial hummingbirds were the least effective pollinators but the most frequent visitors. Flowers were frequently robbed (71%) during the study. Flowers experimentally robbed did not increase nectar production compared to control flowers; therefore, robbery may not involve an extra energy investment in terms of nectar production. The number of pollen grains deposited on artificially robbed flowers was significantly less than the number found in flowers with extra nectar (nectar added) but did not differ from the number found in non-manipulated flowers, indicating that nectar robbers may not affect the foraging behavior of hummingbirds, and therefore pollen deposition.Original Abstract: Realizamos una serie de observaciones y manipulaciones experimentales para determinar el papel que desempenan los miembros del gremio de nectarivoros (polinizadores y robadores) en la produccion de nectar y la deposicion de polen en Hamelia patens, en la Estacion Biologica La Selva (Costa Rica). El gremio de aves nectarivoras que visito las flores de H. patens, estuvo compuesto por siete polinizadores (colibries) y cuatro robadores de nectar (1 colibri y 3 aves de percha) en marzo de 1997. Adicionalmente, se observaron dos especies de aves consumidoras de corolas de H. patens. Los polinizadores realizaron el 85.6 por ciento del total de las visitas a las flores, mientras que los robadores de nectar realizaron el 12.4 por ciento y las aves florivoras el 2 por ciento. La actividad de los polinizadores y robadores aumento durante las horas de mayor disponibilidad de nectar en las flores sin que ocurrieran interacciones agresivas entre ambos gremios. Los polinizadores mostraron diferencias en su capacidad de transportar y depositar polen en el estigma: las especies de colibries territoriales fueron los visitantes mas frecuentes y menos efectivos. Las flores de H. patens presentaron una alta frecuencia de robos (71%) durante el estudio. Las flores robadas experimentalmente no mostraron un aumento en la produccion de nectar en comparacion con las flores control, lo que sugiere que el robo no representa una inversion extra de energia en terminos de produccion de nectar para esta planta. El numero de granos de polen depositado en las flores robadas artificialmente fue significativamente menor al encontrado en flores a las que se les agrego nectar; sin embargo, resulto similar al numero encontrado en flores no manipuladas. Este resultado indica que los robadores de nectar no afectan el comportamiento de forrajeo de los colibries ni la deposicion de polen.

Three hypotheses have been proposed for the evolution of dioecy in figs, invoking seasonality, the reduction of non-pollinating wasp species, and the persistence of pollinator populations within small groups of trees. However, there are two major problems with these ideas. Firstly, dioecy has probably evolved only twice, which severely limits our ability to test between alternative hypotheses. Secondly, it is very simple to suggest ways in which dioecy can evolve from monoecy. To illustrate this problem, and enlarge on some recent progress in our understanding of functionally dioecious figs, we are proposing a few more hypotheses.

It is of conservation interest therefore to understand how rainforest fragmentation may alter the pollination and breeding structure of remnant trees. Previous studies of the Amazonian tree Dinizia excelsa (Fabaceae) found African honeybees (Apis mellifera scutellata) as the predominant pollinators of trees in highly disturbed habitats, transporting pollen up to 3.2 km between pasture trees. Here, using microsatellite genotypes of seed arrays, we compare outcrossing rates and pollen dispersal distances of (i) remnant D. excelsa in three large ranches, and (ii) a population in undisturbed forest in which African honeybees were absent. Self-fertilization was more frequent in the disturbed habitats (14%, n = 277 seeds from 12 mothers) than in undisturbed forest (10%, n = 295 seeds from 13 mothers). Pollen dispersal was extensive in all three ranches compared to undisturbed forest, however. Using a twogener analysis, we estimated a mean pollen dispersal distance of 1509 m in Colosso ranch, assuming an exponential dispersal function, and 212 m in undisturbed forest. The low effective density of D. excelsa in undisturbed forest ( similar to 0.1 trees/ha) indicates that large areas of rainforest must be preserved to maintain minimum viable populations. Our results also suggest, however, that in highly disturbed habitats Apis mellifera may expand genetic neighbourhood areas, thereby linking fragmented and continuous forest populations.

The museum gives architectural form to both abstract concepts and commemorative forms. Libeskind is characterized as a deconstructivist, but a broader view shows him integrating both social and historical ideas about a building, coupled with intention and his own abstract thoughts. History and tradition form the foundation of his practice, and each building tells a story within this context. His dramatic buildings bring the richness of human history and struggle into physical form.

These bombs could potentially be used by terrorists, along with conventional explosives, to create "dirty bombs". Although dirty bombs have never been exploded, there is evidence that terrorists have built such bombs and completed plans to detonate them. These bombs cause panic, preying on fears of radioactivity, and can affect the dislocation of populations. Officials and technicians have been dispatched to survey abandoned radiation sources, including those searching for bombs in Georgia.

This system includes 540 refuges in all 50 states and 12 US territories, for a total of 95 million acres. The history of this system dates to the early conservationist movement and the recognition of threats to species of interest, including pelicans, bison, and grizzly bears. Although these reserves protect much-needed wildlife habitat, there is continued debate about exploitation of grazing, logging, farming, oil drilling, and gas drilling opportunities. The Republican plan for oil drilling in Alaska's Arctic Wildlife Refuge is one such example.

Paper No. 336 N1 - Last updated - 2010-05-03 ER - TY - JOUR T1 - Do multi-branched colonial organisms exceed normal growth after partial mortality? AN - 19401410; 5909381 AB - One of the advantages of modular colonial growth is the capability to recover after partial mortality. Tolerance to partial mortality is a known property of some resistant species of plants that respond to mortality with vigorous regrowth or overcompensation. It is not clear whether modular marine invertebrates such as octocorals overcompensate. This study provides evidence that following injury to colonies (by breaking apical dominance), new growth exceeds normal rates of branching, as observed in some plants, in a degree correlated to the original multi-branched network setting (e.g. the number of original branches connected to main stem), in colonies of the Caribbean gorgonian octocoral Pseudopterogorgia bipinnata. This can be explained by the network of communicating vessels and canals inside octocoral colonies, which provide the structure for effective allocation of resources to regenerating parts.

The factors responsible for among-species differences in mode of development are not well understood and patterns of variation in mode of development have not been documented for many groups. I present a compiled data set of developmental characters for 78 species of calyptraeid gastropods: 53 Crepidula, 9 Calyptraea, 11 Crucibulum and 5 other species. Analysis of this data set shows that egg- and hatching-size distributions are strongly positively skewed. As expected, egg size correlates with hatching size and time to hatching in species without nurse eggs. Egg size is not significantly different between species with planktotrophic development and species with direct development with nurse eggs. Hatching size of direct developers with and without nurse eggs do not differ. Developmental characters do not vary with adult body size among species. There are strong latitudinal effects in mode of development, the frequency of planktotrophic species decreases with increasing latitude while the proportion of direct developers increases. There is also a striking latitudinal pattern in the occurrence of nurse eggs; almost all species with nurse eggs occur in the southern hemisphere. These latitudinal patterns do not appear to be explained by sea surface temperature. Comparisons with other gastropods for which similar compilations are available show a striking difference between heterobranchs (opisthobranchs and pulmonates) and caenogastropods in developmental characteristics.

New aubrites have been recovered in Antarctica, and these meteorites permit a substantial extension of the database on CRE ages, compositional characteristics, and regolith histories. We report He, Ne, and Ar isotopic abundances of nine aubrites and discuss the compositional data, the CRE ages, and regolith histories of this class of achondrites. A Ne three-isotope correlation reveals a solar-type ratio of (super 20) Ne/ (super 22) Ne = 12.1, which is distinct from the present solar wind composition and lower than most ratios observed on the lunar surface. For some aubrites, the cosmic ray-produced noble gas abundances include components produced on the surface of the parent object. The Kr isotopic systematics reveal significant neutron-capture-produced excesses in four aubrites, which is consistent with Sm and Gd isotopic anomalies previously documented in some aubrites. The nominal CRE ages confirm a non-uniform distribution of exposure times, but the evidence for a CRE age cluster appears doubtful. Six meteorites are regolith breccias with solar-type noble gases, and the observed neutron effects indicate a regolith history. ALH aubrites, which were recovered from the same location and are considered to represent a multiple fall, yield differing nominal CRE ages and, if paired, document distinct precompaction histories.

Finds included a dentally complete Homo maxilla (OH 65) with lower face, Oldowan stone artifacts, and butchery-marked bones dated to be between 1.84 and 1.79 million years old. The hominid shows strong affinities to the KNM ER 1470 cranium from Kenya (Homo rudolfensis), a morphotype previously unrecognized at Olduvai. ER 1470 and OH 65 can be accommodated in the H. habilis holotype, casting doubt on H. rudolfensis as a biologically valid taxon.

The beginnings of plant husbandry appear to have been preceded by the exploitation of a wild species of Cucurbita during the terminal Pleistocene. These data provide evidence for an independent emergence of plant food production in lowland South America that was contemporaneous with or slightly before that in highland Mesoamerica.

This campaign is based on studies showing that more structurally complex habitats generally support more diverse faunas. At 10 billion dollars annualy in revenues, coffee is second only to oil in value as a legal export commodity in many parts of Latin America, and in some countries it is the most imporatant source of foreign capital. These statistics mean that large numbers of consumers are involved, who can bring enormous pressure on growers. If significant numbers of people demand shade coffee and are willing to pay for it, then they are going to get it. Nevertheless, we believe there are reasons for caution in employing such a blunt instrument as market forces on such a complex conservation issue.

Resting, feeding and foraging, locomotion, and grooming were the most common behaviors. The most common locomotor behaviors were leaping, scrambling, walking, bounding, vertical bounding, and gliding. The most common postural behaviors were quadrupedal squatting, hind-limb squatting, vertical clinging, clinging, and crouching. Compared with smaller tree squirrels, Sciurus igniventris and Microsciurus flaviventer, P. leucogenys exhibited a higher frequency of 'scrambling' for foraging among terminal branches. The tree squirrels foraged on terminals but fed on larger branches. They also foraged and fed more on vertical surfaces. P. leucogenys spent the most time on small supports, whereas the smallest squirrel (M. flaviventer) spent most on the largest supports.

Sexual reproduction was evaluated by the gonad index method, and by histology of gonad development. In addition, population structure was assessed based on sex ratio, minimum reproductive size, and length and weight distributions of males and females. The sex ratio in both species was 1:1, with a unimodal population distribution composed mainly of mature individuals. The minimum reproductive length and weight were 13-20 cm and 150 g, respectively, for both species, although reproductive individuals 10 cm in length were also found. A consistently higher gonad index was observed in H. mexicana, due to a high proportion of mature females and males and high gonad indices in most monthly samples. Gametogenesis and spawning patterns seemed to occur throughout the year, with periods of enhanced activity. Two periods of maximum reproductive activity were tentatively identified: July-November for I. badionotus and February-July for H. mexicana, but neither species had a single, sharply defined annual spawning event. Further work on these exploited holothuroids should examine the relationships between reproduction and environmental factors and between reproductive status and recruitment.

Impounding altered the hydrology and soil chemistry of the site. In 1997, we established a factorial experiment along a tree-height gradient with three zones, i.e., fringe, transition, dwarf, and three fertilizer treatment levels, i.e., nitrogen (N), phosphorus (P), control, in Mosquito Impoundment 23 on the eastern side of Indian River. Transects traversed the forest perpendicular to the shoreline, from a Rhizophora mangle-dominated fringe through an Avicennia germinans stand of intermediate height, and into a scrub or dwarf stand of A. germinans in the hinterland. Growth rates increased significantly in response to N fertilization. Our growth data indicated that this site is N-limited along the tree-height gradient. After 2 years of N addition, dwarf trees resembled vigorously growing saplings. Addition of N also affected internal dynamics of N and P and caused increases in rates of photosynthesis. These findings contrast with results for a R. mangle-dominated forest in Belize where the fringe is N-limited, but the dwarf zone is P-limited and the transition zone is co-limited by N and P. This study demonstrated that patterns of nutrient limitation in mangrove ecosystems are complex, that not all processes respond similarly to the same nutrient, and that similar habitats are not limited by the same nutrient when different mangrove forests are compared.

Lake-level records since mid-1996 indicate seasonal water elevation variations of ~0.3 m amplitude superimposed on a roughly 'decadal' feature of amplitude ~0.6 m. Using an elastic Green's function and a simplified load geometry for GSL, we calculate that these variations translate into radial crustal loading signals of plus or minus 0.5 mm (seasonal) and plus or minus 1 mm (decadal). The horizontal loading signals are a factor of ~2 smaller. Despite the small size of the expected loading signals, we conclude that we can observe them using GPS time series for the coordinates of these two sites. The observed amplitudes of the variations agree with the predicted decadal variations to <0.5 mm. The observed annual variations, however, disagree; this difference may be caused by some combination of local precipitation-induced site motion, unmodeled loading from other nearby sources, errors in the GSL model, and atmospheric errors.

We studied here one unusual element of their behavioral repertoire: ambush predation. A worker of E. ruidumwaits near a nest of a social sweat bee, Lasioglossum umbripenne, lunging at incoming bees, or less frequently, at departing bees. However, bees detected ambushing ants and modified their behavior. Dead ants placed at bees' nest entrances significantly decreased bee activity, indicating that bees recognized dead ants as potential predators. Neither simple black models (square and rectangle) nor olfactory cues had any effect on overall bee activity. A returning bee usually approached her entrance and immediately entered, but if an ant was waiting at the nest, a bee was significantly more likely to abort the first approach flight and then to re-approach the nest on the side opposite the ant's position. As models became increasingly ant-like, returning bees more frequently aborted their first approach flight, expressing other behaviors before entering nests. These behaviors included withdrawal followed by an approach from a different direction; zigzagging flights, either from a distance or close to the entrance or even a close inspection; landing a short distance from the nest, then approaching on foot or waiting for several seconds before entering. Ants responded with effective counter-behaviors. Behavioral flexibility in nest entering/exiting by L. umbripenneand in hunting strategy by E. ruidumshows the complexity of this predator-prey relationship, and illustrates the importance of information processing by both species involved in determining the outcome of the interspecific interaction.

Phylogenetic analyses grouped this new haplotype in the dog/grey wolf (Canis familiaris/Canis lupus) clade with 98% bootstrap support. These results demonstrate that a male coyote hybridized with a female dog, and female hybrid offspring successfully integrated into the coyote population. The widespread distribution of this haplotype from Florida to West Virginia suggests that the hybridization event occurred long ago before the southeastern USA was colonized by coyotes. However, it could have occurred in the southeastern USA before the main front of coyotes arrived in the area between male coyotes released for sport and a local domestic dog. The introgression of domestic dog genes into the southeastern coyote population does not appear to have substantially affected the coyote's genetic, morphological, or behavioural integrity. However, our results suggest that, contrary to previous reports, hybridization can occur between domestic and wild canids, even when the latter is relatively abundant. Therefore, hybridization may be a greater threat to the persistence of wild canid populations than previously thought.

The dominant predators on grass shrimp, Palaemonetes pugio, are finfish predators that are thought to locate their prey by visual cues. We examined the response of grass shrimp to diel variation in predation risk in the nearshore shallow waters of the Chesapeake Bay. We used diel shoreline seines to assess the relative abundance of predators. We assessed the relative risk of predation with shrimp tethered at refuge (30 cm) and nonrefuge (60 cm) depths. To measure grass shrimp response to predation risk, we used dipnets to monitor habitat use. Four predominantly visual predators dominated the shoreline seine catches, Fundulus heteroclitus, Micropogonias undulatus, Morone americana and Morone saxatilis. Total predator abundance had a diel component, with dramatic nighttime decreases in total abundance, whereas guild composition and relative abundance remained unchanged. Relative predation risk for tethered shrimp exhibited significant time by habitat interaction. During the day, depth negatively affected survivorship of tethered shrimp while at night overall survivorship increased and there was no effect of depth. Shrimp habitats use reflected diel predation risks. Abundances in the near shore were highest during the day with decreased abundances at night. Together, the seine and tethering data highlight the importance for a refuge (e.g. shallow water) from predation during the daytime and a relaxation of predation pressure at night.

A large population of cormorants nesting on Little Galloo Island in Lake Ontario threatened the sport fishing industry. In 1998, a group of fishing guides shot hundreds of the birds and left them to decompose on the island. The men were ultimately fined and sentenced to house arrest. The event polarized local communities reeling in response to the large-scale environmental changes that have impacted their region. The cormorant population in this region capitalized on overabundances of sport fish stocked in the lakes, and ultimately began to compete with sport fisheries.

This astounding archaeological discovery has provided a decade of interest for diagnostic and reconstructive archaeologists. The body dates from the Neolithic age, and represents the best archive of material from this era ever discovered. The body and its relics were preserved in ice, allowing remnants of clothing, food, weapons, and tools to be uncovered. Scientists have reconstructed a death scenario based on broken ribs and the late discovery of an arrowhead embedded in the shoulder.

AN - 14640856; 10639015 AB - Photographer Salgado followed the path of polio immunizers for a year, a journey taking him to Somalia, the Democratic Republic of Congo, India, and Pakistan. Part of the campaign to rid the world of polio by 2005, the immunizers are funded by Unicef and the World Health Organization, among other groups. The $2 billion eradication campaign is not yet complete, despite good progress. Fewer than 1000 cases were noted in 2001, all within ten nations. The campaign is challenged by the capacity of the oral vaccine to mutate and spread, resulting in poliomyelitis. Only the injectable is used in the US.

Although the identity of Heckewelder's informant is uncertain, an item in the vocabulary suggests that it represents the language of the "Eel River Indians"; the words, however, clearly belong to the Sauk-Meskwaki-Kickapoo cluster although seven are inconsistent with Kickapoo, one matches Kickapoo anemwa 'dog' & disagrees with Meskwaki, & four disagree with both. It is concluded that the vocabulary attests a fourth member of the Sauk-Meskwaki-Kickapoo cluster & that, if the Eel River attribution is correct, the language may be that of the Mascouten, who merged early with the Kickapoo. 40 References.

This program introduced citrus (Citrus spp.) and promoted the widespread inclusion of poro (Erythrina poeppigiana) shade trees, ground story vegetation, and soil conservation techniques to the local cultivation of coffee (Coffea arabica var caturra). This program sought long-term socioeconomic and ecological health in these buffer zone communities through conservation and development projects such as coffee agroforestry systems. This paper examines the ecological and socioeconomic benefits of two introduced coffee agroforestry systems: coffee-poro and coffee-citrus. The project has decreased agrochemical inputs, integrated multi-strata vegetation, and implemented soil conservation techniques such as vetiver grass, cover crops, terraces, water channeling, and shade trees in an effort to sustainably manage coffee production on the steep buffer zone slopes. The agroforestry project of the AMISCONDE Initiative has likely improved the production of coffee ecologically and economically. However, new specialty markets should be explored to increase economic and ecological gains. Organic and fair trade coffee niche markets are suggested as alternatives for meeting the long-term AMISCONDE objectives of community development and conservation.

Part One. AN - 62174815; ED480601 AB - The monetary system in the U.S. colonies was notable because it was based on thin air. The earliest forms of U.S. money were commodities, items that were not just tokens of wealth but had some intrinsic value. In addition to adopting the Indians' use of wampum and furs, the colonists used crops and European-made items such as nails. In 1775, the Continental Congress issued the colonies' first uniform currency, the bills that came to be called "Continental." The colonies, soon to call themselves states, issued their own bills. Like the Continentals, this money served to finance and to promote the Revolutionary War. This booklet from the Smithsonian contains two lesson plans on the money of the period. Lesson (1) "Money Talks," students move from fact finding to interpretations as they examine paper money from the time of the Revolutionary War; and Lesson (2) "Pictures Telling Stories," shows not only the importance of primary sources in the study of U.S. history but also the limitations of relying only on primary sources of taking the money on face value. Both lessons address materials and preparation and provides a step-by-step procedure for classroom implementation. Contains photos of the paper money and a glossary of Latin inscriptions.

Smithsonian in Your Classroom. AN - 62166677; ED480603 AB - When Orville and Wilbur Wright began their studies of aviation, they did not overlook the great experts on the subject the birds. The brothers became interested in flight as children, when their father brought home a little flying toy powered by a rubber band. Later, they corresponded with the Smithsonian Institution (Washington, DC) which sent them pamphlets and a book about flight. On December 17, 1903, Orville Wright flew in a motor-powered craft for 12 seconds across 120 feet of sand near Kitty Hawk, North Carolina. This lesson plan, "Who, What, Where, Why," offers a background essay; presents preparation information and a vocabulary; and provides a step-by-step procedure for classroom implementation. The lesson plan also addresses assessment and curriculum enrichment. Contains photographs, letters, a magazine interview, and a newspaper story about the flight (the primary sources). Lists six Web sites, five books for teachers, and several books for students.

In addressing the current proliferation crises with North Korea & Iran, however, the Bush administration confronts major constraints on both the use of force & the US ability to bring about regime change. This has prompted a shift in strategy to the alternative combination of deterrence & reassurance. Implementing a strategy of deterrence & reassurance requires effective policy coordination to ensure that the two components are in sync. Military moves for purposes of deterrence should not undercut the message of political reassurance & thereby provide further incentive for either country to cross the nuclear threshold.

Outcrop-based sequence stratigraphic analysis on the upper Wabaunsee, Admire, and lower Council Grove groups in Kansas and Nebraska reveals a hierarchy of fifty-one fifth-order meter-scale cycles grouped into five fourth-order composite sequences. Fifth-order cycles are bounded by subaerial unconformities in nearshore settings and correlative conformities in offshore settings, and are therefore very thin depositional sequences. Lowstand systems tracts, observed only in nearshore deposits, are expressed as sandy, incised-valley fills in these meter-scale cycles. Transgressive systems tracts, which are dominated by carbonate deposition, include coastal evaporites indicating arid climatic conditions. Highstand systems tracts, which are dominated by siliciclastic deposition, include thin but persistent coals in muddy coastal successions indicating humid climatic conditions. Paleosols at sequence boundaries evolve from vertic to calcic, indicating climate change from relatively humid to relatively arid conditions during subaerial exposure. This indicates that relatively arid climate coincided with eustatic lows while relatively humid climate coincided with eustatic highs on this low-latitude platform. Composite sequences are bounded by subaerial, angular unconformities and display a transgressive-regressive stacking pattern of meter-scale cycles. The high-resolution stratigraphic record of the Midcontinent helps constrain the rate and magnitude of environmental change in ancient icehouse conditions and can serve as a baseline of environmental change for comparison with other coeval successions.

Phylogenetic analyses indicate that this long coevolutionary history includes a third symbiont lineage: specialized microfungal parasites of the ants' fungus gardens. At ancient levels, the phylogenies of the three symbionts are perfectly congruent, revealing that the ant-microbe symbiosis is the product of tripartite coevolution between the farming ants, their cultivars, and the garden parasites. At recent phylogenetic levels, coevolution has been punctuated by occasional host-switching by the parasite, thus intensifying continuous coadaptation between symbionts in a tripartite arms race.

At 298 K, the lower valence cations, such as Mn (super 3+) , occupy large octahedral sites at the edges of the triple chains, and four water/cation sites are in the tunnels. In our heating experiments in vacuum, todorokite began to break down at approximately 450 K and fully decomposed by 620 K, at which point hausmannite started to form. Our results suggest that the loss of O (sub 2) accompanied the reduction of Mn (super 4+) to Mn (super 3+) and Mn (super 2+) , and these reactions impelled a breakdown of the octahedral framework and the subsequent release of the tunnel water molecules. Rietveld refinements revealed a gradual thermal expansion of todorokite structure to approximately 450 K. At higher temperatures, the unit-cell volume gradually decreased, primarily as a result of a decrease in c, and the decline in beta with increasing temperature was accelerated. A mechanism for forming the inverse spinel hausmannite structure from todorokite is presented.

Large-ion lithophile elements (potassium and barium) were added to eclogite (subducted basalt) during high pressure/temperature metamorphism via phengite crystallization from subduction zone fluids.

Here we show that the onset of this extremely warm interval is associated with a stepped terrestrial carbon isotope (delta (super 13) C) excursion. This suggests that a pulsed sublimation of submarine gas hydrate accumulations at this time may have caused a rapid venting of significant quantities of light carbon through the ocean/atmosphere interface. Major mammalian turnover occurred near the onset of the ensuing greenhouse event, and this also appears to have occurred in a sequential fashion, although the changes we see in population composition and morphology lag the major features of the global delta (super 13) C record by some approximately 10-20 k.y., which could represent the duration required for evolutionary mechanisms to occur due to greenhouse-associated stresses. Additionally, we have evidence that increased soil respiration rates occurred in response to the core episode of global warmth. Paleocene-Eocene boundary carbon cycle perturbations were apparently as remarkable in the atmospheric and terrestrial reservoirs as they were in the oceans, and these changes had a dramatic effect on terrestrial biota.

During at least 30 k.y. of this carbon cycle perturbation, euhedral barite apparently accumulated in deep-sea sediment faster than before or after. This excess burial of "biogenic barite" has been argued to reflect elevated global primary productivity in surface waters, an interpretation in disagreement with microfossil assemblages. In this paper, we develop a numerical model for the marine Ba cycle to explore possible mechanisms for widespread barite accumulation. This model immediately highlights a fundamental problem with the productivity explanation: Ba has a short residence time in the ocean ( approximately 8000 yr) so that excess Ba output on a global scale over periods <1000 yr signifies excess Ba input. However, a greater Ba input from conventional sources, hydrothermal waters and rivers, seems untenable. Assuming that available Ba records represent increased global output, we suggest an unconventional explanation for widespread barite accumulation. Prior to the PETM, gas hydrate reservoirs stored enormous masses of CH (sub 4) and dissolved Ba (super 2+) . During the PETM, substantial quantities of gas hydrate converted to free CH (sub 4) gas, increasing pore pressures, and releasing significant amounts of CH (sub 4) and dissolved Ba (super 2+) to intermediate waters of the ocean. Consequently, dissolved Ba (super 2+) concentrations in the deep ocean rose, a smaller fraction of sinking barite particles dissolved, and "biogenic barite" accumulation increased. The model satisfactorily explains available records but forces us to link components of the marine CH (sub 4) and Ba cycles, an endeavor with few constraints.

A detailed record of benthic foraminiferal faunal change over approximately 30 k.y. across the carbon isotopic excursion at Ocean Drilling Program Site 690 (Southern Ocean) shows that shortly before the CIE absolute benthic foraminiferal abundance at that site started to increase. "Doomed species" began to decrease in abundance at the CIE, and became smaller and more thin-walled. The main phase of extinction postdated the CIE by a few thousand years. After the extinction faunas were dominated by small species, which resemble opportunistic taxa under high-productivity regions in the present oceans. Calcareous nannofossils (primary producers), however, show a transition to more oligotrophic nannofloras exactly where the benthic faunas show the opposite. Plankton and benthos is thus decoupled. Possibly, a larger fraction of food particles reached the seafloor after the CIE, so that food for benthos increased although productivity declined. Enhanced organic preservation might have resulted from low-oxygen conditions caused by oxidation of methane. Alternatively, and speculatively, there was a food-source at the ocean-floor. Benthic foraminifera dominating the post-extinction fauna resemble living species that symbiotically use chemosynthetic bacteria at cold seeps. During increased, diffuse methane escape from hydrates, sulfate-reducing bacteria could have produced sulfide used by chemosynthetic bacteria, which in turn were used by the benthic foraminifera, causing extinction by a change in food supply.

Yet, its chronostratigraphy is disputed: Most accounts placed it well before the Initial Eocene Thermal Maximum (IETM). More recently, it was suggested that the LFT and the IETM might be coeval; in turn, this possibility was questioned because it relied on correlation of inner neritic and deep-marine sections, and only in the latter the IETM had been recognized. To resolve this controversy, two new sections have been studied in the Pyrenees. In the Urrobi section, composed of proximal outer-platform carbonates, the LFT occurs within a conspicuous 70-cm-thick layer of sandy marls, informally named the "Nummulites Band." The Mintxate section consists of distal outer-platform carbonates and thin marls, but includes a prominent 2-m-thick marly layer correlatable with the Nummulites Band. Planktic foraminifera demonstrate that this marly layer, and the Nummulites Band, pertains to the middle part of Zone P5, the interval during which the IETM took place. This dating is confirmed with calcareous nannofossils from Mintxate and with analysis of carbon isotopes of bulk samples from both sections. The biotic impact of the IETM was thus greater than previously reported, having also led to migration and/or specialization of larger foraminifera. These organisms formed widespread accumulations on the early Paleogene carbonate platforms girding the Tethys Ocean. In these successions, the LFT is easily recognizable and constitutes an excellent marker for the base of the Eocene Series.

Here a rich fossil record is known from a stratigraphic section with an established geomagnetic polarity time scale and medium- to high-resolution carbon and oxygen isotope records. The Paleocene-Eocene carbon isotope excursion (CIE) and temperature maximum (PETM) associated with greenhouse warming are both represented, starting at ca.55 Ma and lasting approximately 86 k.y., during the transition from Paleocene to Eocene epochs and from Clarkforkian to Wasatchian land-mammal ages. Attention is focused on transient dwarfing of earliest Wasatchian (Wa-0) mammals during the CIE-PETM interval and on more lasting changes in generic composition and diversity. Faunal changes lagged initiation of the CIE by some 13 and 22 k.y., consistent with the idea of a stepped and pulsed response to climate change. Body size dwarfing in Wa-0 mammals cannot be explained as a response to temperature alone, and elevated atmospheric CO (sub 2) probably played an important role.

Our data show that for much of the late Paleocene to middle Eocene, complex, species-rich forests were predominant in southeastern Australia, under mesothermal humid climates (mean annual temperature 16-22 degrees C, coldest quarter mean temperature >10 degrees C, mean annual precipitation >150 cm/yr). A minor cooling episode may have occurred in the mid-early Eocene. Megathermal climates may have been present in lowlands in the latest early Eocene, during the Cenozoic Global Climatic Optimum. These forests were dominated by taxa characteristic of present-day mesothermal-megathermal high-rainfall multistratal forests; e.g., Cunoniaceae, Elaeocarpaceae, Gymnostoma (Casuarinaceae), Lauraceae (e.g., Beilschmiedia, Cryptocarya and Endiandra), and Proteaceae. A prominent treefern element (Cyathea and Dicksonia types) was present in the early Eocene. A number of megathermal taxa, including Cupanieae (Sapindaceae) and Ilex (Aquifoliaceae), were present through the early and middle Eocene. Taxa characteristic of modern-day microthermal to mesothermal forests were also present, e.g., Nothofagus (Nothofagaceae), Eucryphia (Eucryphiaceae), Libocedrus (Cupressaceae) and Podocarpaceae (Acmopyle and Dacrycarpus). The relictual araucarian conifer, Wollemia, and other Araucariaceae were present through the late Paleocene to early Eocene. There is limited physiognomic evidence to suggest the late Paleocene to early Eocene forests contained some deciduous canopy trees.

A main limitation of those studies has been the lack of interaction between dynamical ocean and atmospheric models. After reviewing previous model studies and quantitatively defining the "low gradient problem", we present results from the first fully coupled general circulation model simulations in equilibrium with reconstructed early Paleogene topography, bathymetry, vegetation, and pCO (sub 2) (560 ppm). Although our results should be understood as preliminary, predictions of both Paleogene sea surface temperatures and salinities are, for the first time, made without assuming an arbitrary value of the oceanic or atmospheric heat transport. Model-predicted bottom water temperatures are 7 degrees C warmer than modern. Deep convection occurs in the North Atlantic and Tethys, forming warm (12-15 degrees C), salty water masses (35.5 ppt). Through most of the Southern Ocean, vigorous wind-driven upwelling and a stable water column caused by low salinities ( approximately 32 ppt) produce a temperature inversion that may explain proxy interpretations of "warm salty deep water" formation in the tropics. Estimates of seawater oxygen isotopic ratios reveal substantially different patterns than usually predicted. Ocean heat transport is little-changed from modern values and warming of tropical temperatures (by approximately 3 degrees C) is about half that occurring in high latitudes. The mean annual temperature and seasonality patterns produced by the simulation are biased toward colder and more seasonal values than those reconstructed from temperature proxies.

In southern areas, the inner to middle neritic (30-70 m) Neoeponides duwi assemblage expanded into deeper parts of the shelf ( approximately 70-250 m), temporarily replacing the Anomalinoides umboniferus and Angulogavelinella avnimelechi assemblages. In the deeper parts of the basin ( approximately 400-600 m) in the northern part of the transect, the Gavelinella beccariiformis assemblage appears to have been persistent throughout the studied time interval. Biofacial and sedimentologic data suggest a relative sea-level fluctuation, possibly with an amplitude of 50-100 m, which may correlate with a eustatic sea-level cycle during the Danian-Selandian transition. During early sea-level rise, total organic carbon-enriched, partially laminated sediments, containing abundant fish-remains and planktic foraminifera (>99.5% planktics), were deposited, reflecting oxygen deficiency at the seafloor. The patterns of biotic and sea-level change at the Danian-Selandian transition strongly resemble those across the Paleocene-Eocene Thermal Maximum in the same basin, suggesting similar operative processes. Considering the close coincidence with a recently postulated brief period of oceanic warming at 60.5 Ma, the question arises whether the observed patterns in Egypt could in part be related to a global warming event, similar to the Paleocene-Eocene Thermal Maximum.

We derived a cyclostratigraphy by using spectral analysis of high-resolution records of elemental concentrations obtained by an X-ray fluorescence (XRF) Core Scanner. XRF counts of iron serve as a proxy for the relative amount of terrestrial material. Sliding-window spectral analysis, bandpass filtering, and direct counting of precession and obliquity cycles yield minimum durations for magnetic polarity chrons C22 to C26 ( approximately 49 to approximately 61 Ma), calculations of sediment accumulation rates, as well as constrains on the timing of biostratigraphic and climatological events in the vicinity of the Initial Eocene Thermal Maximum (IETM). Durations of polarity chrons as represented in sediments drilled at Site 1051 were estimated using a conservative assignment of 41 k.y. for obliquity cycles and 21 k.y. for precession cycles. Combined polarity chrons C26r and C26n span 3.61 m.y., and chron C25r spans 1.07 m.y. Polarity chron C24r is estimated as 2.877 m.y. The interpretation of polarity chron C24n is ambiguous, but its duration is probably <1.23 m.y. Polarity chron C23r spans 0.53 m.y., chron C23n is 0.74 m.y., and chron C22r is 0.9 m.y. Spectral analysis through this interval indicates that spectral peaks shift through time and are related to changes in sedimentation rate at Site 1051.

Carbon isotope analysis has demonstrated a negative carbon isotope excursion similar to that seen in the lower part of the carbon isotope excursion that marks the onset of the Paleocene-Eocene Thermal Maximum (PETM) elsewhere in the marine and continental record. The carbon isotope excursion interval in the Cobham Lignite is shown to be characterized by repeated fires in a vegetation dominated by flowering plant trees and herbs and with many ferns. The abundance of ferns is likely to be a response to disturbance caused by fires. This detailed evidence from across the early PETM (as identified by stratigraphic context and a negative carbon isotope excursion), combined with data from less stratigraphically resolved, but almost coeval, macrofloras from other southern English sites, shows that there is no major change in vegetation at this time in southern England. In contrast, vegetation change occurs later with the emplacement of floras of the Eocene Thermal Maximum. Although there is no obvious vegetation response to the global warming at the PETM, the abundance and consistent occurrence of charcoal in this interval is unparalleled elsewhere in the southern English Paleogene. Therefore, repeated fires, at least on a local scale, may have been one environmental response to the events around the PETM.

In this study, we incorporate more realistic orbital forcing, topography, vegetation, and sea surface temperatures than have previously been included in early Eocene modeling experiments. By considering two cases that represent the end members of a realistic precessional cycle, we attempt to constrain the magnitude of climatic variability due to this orbital parameter. Model results for the western interior of North America indicate very small ( approximately 1 degrees C) differences in mean annual temperature (MAT) and cold month mean (CMM) temperature in response to the imposed precessional cycle. Seasonally, the greatest temperature response to the orbital forcing occurs in summer ( approximately 6 degrees C). Mean annual precipitation (MAP) in the region shows little variability between cases either annually or seasonally (>10%) with the exception of autumn ( approximately 50%). Our MAT, CMM, MAP, and mean annual temperature range (MATR) results are generally consistent with proxy data interpretations. These results have implications for the interpretation of cyclic desiccation recorded in the lithologies of the Wilkins Peak member of the Eocene Green River Formation (GRF). The low modeled sensitivity of MAT and MAP to precessional forcing implies that the lithologic cycles found in the GRF may not be a consequence of dramatic swings in climate across a precessional cycle, but rather are a consequence of the extremely high climatic sensitivity of the sedimentary processes that formed the Wilkins Peak member. These results also have implications for the interpretation of recent high temporal resolution studies of Paleogene climate that indicate significant shifts in MAT ( approximately 1-12 degrees C) over relatively short ( approximately 1 m.y.) time scales. Our modeling cases indicate that precession could account for some portion of this short-term climate variability. However, variability due to precession is of higher frequency and lower amplitude than the MAT fluctuations inferred from the paleontological record, implying that the dominant cause(s) of these fluctuations remain(s) to be identified.

The first immigration brought the first adapines that replaced cercamoniine prosimians, and the first palaeotheriids that replaced, step by step, equids. It is also at this time that the first bunoselenodont and selenodont artiodactyls appear and replace the brachyo- and bunodont forms of the early Eocene and the early middle Eocene. The second immigration brought the first anoplotheriid artiodactyls, and led to a considerable replacement of taxa among the palaeotheriids. There is no indication that the two immigrations originated from outside of Europe although their origin is still enigmatic. The appearance of certain paleobiologic adaptations indicates that, except for the appearance of land bridges, paleoclimatic development may have played a role in these migrations.

Paleocene faunal successions are far less documented in Europe. A major lacertilian faunal turnover occurs across the Paleocene-Eocene boundary, with a strong increase in diversity during the early Eocene. Families represented during the Paleocene are still present in the early Eocene, and new taxa (Agamidae, Iguanidae (super *) , Varanidae, Gekkonidae, Glyptosaurinae) appear in the locality of Dormaal (earliest Eocene). Some important changes in ecology (diet, size) seem to affect the lizard community during the Paleocene-Eocene events. An increase in richness of insect eaters and carnivorous lizards between Paleocene and early Eocene faunas is noteworthy. New carnivorous (Varanidae) and insectivorous lizards (Iguanidae (super *) , Agamidae) enter the intermediate size class during the transition. More equable climate may have allowed immigration through highlatitude routes. The area of origin of these newcomers has not been identified.

We used standard and regional scales based on seven microfossil groups (planktonic and benthic foraminifers, nannoplankton, radiolaria, diatoms, silicoflagellates, and dinocysts) to correlate various sediment facies among approximately 80 reference sections across the study area. Correlation was performed for the Transitional province, where the presence of both calcareous and siliceous facies affords the use of calcareous and siliceous planktonic and dinocyst scales with varying resolutions. Besides, in the Transitional province, we established regional sedimentary cycles corresponding to the late Thanetian, Ypresian, and late Lutetian-Bartonian. These cycles are traceable into the Northern province, enabling us to determine or refine ages of the sequences, and into the Southern province. Each sedimentary supercycle falls into three units, often with hiatus at the base, correlatable to 3rd order eustatic cycles and featured by distinctive facies. The facies succession appears to reiterate through the upper Thanetian, Ypresian, and upper Lutetian-Bartonian cycles. The lower units of each supercycle are composed of calcareous sediments rich in nannofossils and foraminifers and are traceable from the Southern province into the Transitional province, the late Lutetian unit extending as far as the Northern province. The middle unit is high in organic matter in the Southern province and passes into terrigenous-siliceous sediments rich in radiolaria, diatoms, and dinocysts in the Transitional and Northern provinces. The upper unit is terrigenous-carbonate and, in places, terrigenous-siliceous in the Southern province, becoming terrigenous-siliceous and biogenic siliceous (spongolites, diatomites) in the Transitional and Northern provinces. Calcareous plankton (lower unit) giving way to siliceous (upper unit) might record changes in basinal circulation due to Peri-Tethys communicating with the North Atlantic and/or Arctic. The sedimentary provinces shifted southward as the Peri-Tethys shrank and climate changed between the Thanetian and Bartonian.

Although floral change across the Paleocene-Eocene transition has been studied in many areas, few fossils demonstrably come from the approximately 200 k.y.-long IETM. The rarity of fossils from the IETM permits two end-member hypotheses: (1) IETM floras were similar to, or intermediate in composition between, Paleocene and Eocene floras, or (2) they were distinct from both Paleocene and Eocene assemblages in having a high proportion of taxa that were temporary, thermophilic immigrants. The latter hypothesis is consistent with expectations developed from the study of late Quaternary floras, which demonstrate rapid northward range displacements in the wake of retreating continental glaciers. Here we report lithological, paleontological and isotopic evidence for a Paleocene-Eocene boundary section in the lower Wasatch Formation of the southwestern Powder River Basin, Wyoming. Pollen samples from within the IETM interval do not record immigrants from the south, making it unlikely that there were rapid, continental-scale range displacements during the IETM. Floral response consisted of shifts in the relative abundances of native taxa at the beginning of, or even prior to, the IETM, followed by immigration of taxa from outside of North America, probably Europe, near the end of, or possibly after, the IETM.

A negative carbon excursion has been identified within C24r and is bracketed by a late Tiffanian or Clarkforkian fossil site and an early Wasatchian (Wa-1) site. The range in delta (super 13) C values is from -14.08 per mil to -8.14 per mil. Outcrops in Big Bend National Park are North America's most southern exposure of early Paleogene continental deposits in which the Paleocene-Eocene boundary is constrained by terrestrial mammal localities. The exposures are mostly red and black mudstones, the colors of which result from pedogenic processes. Common pedogenic features of the red paleosols are slickensides, sub angular, blocky peds, carbonate nodules, redoximorphic features, and Gilgai microrelief. Smectite is the most abundant clay mineral present. Quartz, calcite and plagioclase make up the remaining bulk of their mineralogy. These ancient soils are interpreted to have formed mainly under dry conditions with seasonal wetting and a fluctuating water table. Black paleosols are less common than red paleosols in the Paleocene and absent from the Eocene. Slickensides and sub angular blocky peds are common pedogenic features in them. The smectite content of black paleosols is much higher compared to that of red paleosols, and they contain significantly less calcite and plagioclase. Black paleosols formed under very wet and poorly drained conditions in which calcite and plagioclase were leached and authigenic smectite was produced. Due to the condensed nature of the section as well as pedogenic overprinting, the interpretation of the negative carbon excursion is complex, as is its effects on pedogenic processes. During this global warming event, changes in pedogenesis did occur and resulted in a significant increase in the translocation of clays and the leaching of calcite and plagioclase. This increase in the weathering profile may have been caused by an increase in mean annual temperature and rainfall. Integrated research over the past decade has led to the recognition of a short 150-200 k.y.) interval of Paleogene time within Chron C24r at approximately 55.5 Ma, formerly termed the late Paleocene Thermal Maximum (LPTM) but more recently the Paleocene-Eocene Thermal Maximum (PETM), that was crucial in the climatic, paleoceanographic, and biotic evolution of our planet. Stable isotope analysis of marine carbonates indicates that there were transient changes in surface and deep-water temperatures. These climatic changes coincided with a negative 3 per mil-4 per mil carbon isotope excursion (CIE), which is recorded in both marine and terrestrial deposits. It was soon realized that the CIE not only constitutes a powerful tool for long distance ("global") isochronous correlation, but even more importantly that it is coeval with notable biotic events in both marine and continental fossil records that have long been taken as criteria for the beginning of the Eocene in North America and more recently in deep sea cores. On the other hand, the conventional Paleocene/Eocene boundary level at the Thanetian/Ypresian boundary in Belgium and the London Basin has been found to be approximately 1 m.y. younger than the CIE, based on the association of the First Appearance Datum (FAD) of the (calcareous nanno-plankton) Tribrachiatus digitalis (at approximately 54.4 Ma) with the base of the Ypresian in the London Basin. Although the Ypresian definition would take priority under normal circumstances, a consensus has been reached to redefine the Eocene in recognition of the worldwide significance and correlatibility of stratigraphic features associated with the PETM. Redefinition of the Eocene, however desirable, nevertheless cannot proceed in a stratigraphic vacuum, and this paper is concerned with resolving the consequences of this action. To be made coincident with the CIE at approximately 55.5 Ma, the Ypresian/Thanetian boundary would have to be lowered by approximately 1 m.y., resulting in the inflation of the span of the Ypresian by 20% and a reduction of the span of the Thanetian by 30%. At the same time, the terminology of the strata in the leapfrogged interval would be thrown into total conflict with the literature, with the substitution of one widely used stage name for the other in the conflicted interval. On the other hand, to relocate the Paleocene/Eocene boundary without moving the stage boundaries would result in the upper third of the Thanetian falling within the Eocene, demolishing a century-old consensus. We propose that the destabilizing effect of the new boundary in the classic chronostratigraphy of western Europe can best be minimized with the introduction of a pre-Ypresian Stage, to encompass the orphaned upper Thanetian interval as the basal unit of the Eocene under a separate name. To this end, we suggest the reintroduction of the Sparnacian Stage, now that its original concept has been shown to correlate essentially with the interval between the CIE and the FAD of T. digitalis.

The specialized depth ecologies were related to the initiation of photosymbiosis as a trophic strategy within the last representatives of Praemurica inconstans. Our data confirm that Acarinina and Morozovella lived in the surface mixed layer, since they record lower delta (super 18) O and higher delta (super 13) C than contemporaneous Globanomalina and Subbotina. However, prior to 56.5 Ma, the data from the southeastern Indian Ocean (Ocean Drilling Program Hole 761B) show a clear separation in both oxygen and carbon isotopes between Morozovella and Acarinina, suggesting that the latter calcified slightly deeper in the photic zone than the former. The water column during the Paleocene appears to have been more stratified, in terms of plankton communities, than previously realized and the resulting creation of different depth habitats played an important role in plankton diversification. The surface waters over the subtropical Indian Ocean probably had a shallower mixed layer and a stronger thermal gradient than, for example, that of the mid-Pacific where the delta (super 18) O offsets between different species of planktonic foraminifera are less pronounced. The different genera of planktonic foraminifera established distinct surface-ocean, shallow thermocline, and deep thermocline depth habitats that remained occupied by related species groups throughout the Paleocene. The invasion of planktonic foraminifera into the oligotrophic gyres during the middle Paleocene led to a significant diversification that was fueled by photosymbiosis in the planktonic foraminifera.

In the sapropelitic bed, calcareous plankton decreased in abundance, a benthic foraminiferal extinction occurred, dinocysts were abundant, and there were abnormally thick-walled dinocysts and asymmetric calcareous nannoplankton species. We argue that the sapropelitic bed accumulated as a result of high productivity, triggered by an influx of nutrients that reached the basin when organic- and P-rich sediments in low-lying coastal areas were flooded during a rapid transgression. High productivity led to oxygen depletion, decimating benthic foraminiferal assemblages. Organic biomarkers suggest that at least in some places even waters in the photic zone became anoxic. The dysoxia/anoxia might have been exacerbated by stratification, resulting from high runoff in the humid western region, high evaporation in the arid eastern area. Anoxia/dysoxia ended gradually. We suggest that deposition of large amounts of organic matter in the northeastern Peri-Tethys may have been a factor in terminating the IETM.

Although both of these intervals are representative of globally warm climates, my CO (sub 2) reconstruction indicates near present-day values (300-450 ppmV) for both times. Although these data do not cast doubt on the theory of the greenhouse effect, they do suggest that other thermal forcings were more important during these intervals than they are today.

Analyses indicate that the age of the continental Walbeck mammal fauna (Germany) is close to that of the Upper Selandian Heers Formation of Belgium (NP4-5). The MP6 reference-level of Cernay (France) is probably correlated with the lower part of NP9 (late Thanetian). The MP7-MP8+9 intermediate faunas of Meudon and Pourcy could be partly equivalent in age to Biochron NP10. The MP8+9 reference-level of Avenay corresponds to the upper part of the London Clay and Kortrijk Formations, which are of late middle Ypresian age (lower NP12), or to the lower part of the Wittering and Tielt Formations, which are dated early late Ypresian (middle NP12). The MP10 Grauves and Premontre faunas (France) are correlated with the NP13 Upper Wittering Formation. The taphonomy of terrestrial mammals discoverd in marine deposits indicates several origins of the material such as reworking, action of predators or fluvial transport.

The onset of the carbon isotope excursion (CIE), positioned at the base of the Tienen Formation, is shown to precisely coincide with the onset of a massive Apectodinium abundance, and to be coincident or very close to the development of deeply incised paleovalleys. The organic carbon isotope curve recorded in the lagoonal settings of northern Belgium, presents a complex structure, marked by multiple anomalies and, consequently, is not believed to result from a single instantaneous event. The most negative values (75%) in the lower part of the Tienen Formation. However, the range of the Apectodinium acme (>50%) suggests that the IETM probably lasted until the end of the deposition of the Tienen Formation. The kaolinite influxes at its base and within its middle part are proved to be unrelated to the CIE. The integration of the dinoflagellate cyst and the carbon isotope data has led to the establishment of a refined chronostratigraphic framework, allowing the depositional history of the southern North Sea Basin to be deciphered. During pre-IETM and post-IETM times widely uniform marine depositional regimes existed throughout the area because of tectonic quiescence. This strongly contrasted with the IETM interval, which is marked by restricted complex lagoonal conditions and differential subsidence. In spite of the extreme warm climate and the tectonic instability of the area, vegetation was relatively stable across the IETM and marked by low extinction and first-occurrence rates.

In three different measured sections, soil carbonate delta (super 13) C values change in phase with marine surface water carbonates on both long ( approximately 7 m.y.) and short ( approximately 100 k.y.) time scales. The carbon cycle perturbations at the Paleocene-Eocene Boundary Thermal Maximum (PETM) and the Eocene Warm Interval (EWI) are recorded in multiple sections, providing unambiguous links between marine and continental deposits. The PETM and EWI delta (super 13) C excursions in the Bighorn Basin are larger than those in the surface ocean, but the reasons for this amplification are unclear. Organic matter samples from the Bighorn Basin yield noisy delta (super 13) C records that do not mirror global changes, perhaps due to diagenetic alteration or postformational contamination. The delta (super 18) O values of soil carbonate are subject to multiple climatic influences that are often antagonistic. Although the delta (super 18) O shifts at the PETM and EWI are small, the shift at the PETM is statistically significant in two of the measured sections. Assuming a plausible range of values for the meteoric water delta (super 18) O/mean annual temperature relationship, the perturbation in soil carbonate delta (super 18) O at the PETM is consistent with an increase in meteoric water delta (super 18) O of approximately 2 per mil and changes in local temperature of 3-7 degrees C.

The Tethys separated Europe from Africa to the south, and the West Siberian Sea and Turgai Straits separated Europe from Asia to the east. Using cladistic analysis and paleogeographic reconstructions, three cases of multiple land mammal dispersal across the Turgai Straits from Asia to Europe in the late Paleocene and early Eocene are recognized. Two of these involve the hyopsodontid condylarths Lessnessina (with its synonym Midiagnus, and including the species L. khushuensis sp. nov.) and a Hyopsodus clade (H. orientalis+H. itinerans), which most likely entered Europe early in the Eocene at approximately 54.5 Ma. The third case is of the order Perissodactyla, whose analysis provides an early history of global dispersal for the group. It indicates that their entry into Europe was earlier than for the hyopsodontids, in the latest Paleocene, perhaps at approximately 56.5 Ma. As the Turgai Straits are at mid latitudes, not high latitudes like the Bering and Greenland land bridges, it is unlikely that ameliorating climate was the driving force behind these three dispersals. The cause was most likely low sea levels, providing either a narrow land bridge or a greatly narrowed strait, allowing rafting.

To detect to what extent vegetation in a mid to high latitude Southern Hemisphere region responded to this intense warming interval, plant microfossils have been examined from a well-calibrated IETM marine sequence at Tawanui, New Zealand. Spore and pollen assemblages remained relatively stable across the IETM, with few notable changes. Pollen from an araucarian conifer, Dilwynites granulatus (Wollemi Pine), dominated the assemblages and the only notable local appearance near the beginning of the IETM was Spinizonocolpites prominatus (Nypa mangrove palm). The spore and pollen assemblage indicates that a mesothermal conifer-dominated multistratal rainforest, suggestive of a warm climate with high rainfall, was the predominant plant community. Megathermal coastal Nypa mangrove communities appear to have been established in New Zealand prior to the IETM, and the intense warming interval was not associated with significant immigrations and turnover events in plant communities. Rather, we suggest that the subtle variations recognized, primarily an increase in D. granulatus pollen at the beginning of the IETM, may reflect an increase in terrigenous inputs to the marine environment in the Tawanui region during the IETM. The lack of a clear response in plant communities to this aberrant event is in agreement with current observations from other mid to high latitude settings in both the Northern and Southern Hemispheres.

The section contains deposits from calcareous nannoplankton Zones NP9 and NP10 and displays the global negative carbon isotope excursion (CIE) in the upper part of Zone NP9. Associated with the CIE is a strong three-fold increase in the rate of hemipelagic sedimentation. This suggests an increased input of siliciclastic suspended material into the basin, which is indicative of enhanced continental run-off at that stratigraphic level. Concurrent acmes of siliceous plankton and dinoflagellate cysts indicate that a high input of dissolved nutrients affected even open marine settings and caused eutrophication of surface waters. The associated high flux of organic carbon to the seafloor resulted in oxygen-depleted conditions and caused the total extinction of benthic faunas. However, impoverished foraminifera faunas indicate that a change of ecological conditions started shortly before the CIE.

Stable isotope analysis of marine carbonates indicates that there were transient changes in surface and deep-water temperatures. These climatic changes coincided with a negative 3 per mil-%4 per mil carbon isotope excursion (CIE), which is recorded in both marine and terrestrial deposits. It was soon realized that the CIE not only constitutes a powerful tool for long distance ("global") isochronous correlation, but even more importantly that it is coeval with notable biotic events in both marine and continental fossil records that have long been taken as criteria for the beginning of the Eocene in North America and more recently in deep sea cores. On the other hand, the conventional Paleocene/Eocene boundary level at the Thanetian/Ypresian boundary in Belgium and the London Basin has been found to be approximately 1 m.y. younger than the CIE, based on the association of the First Appearance Datum (FAD) of the (calcareous nanno-plankton) Tribrachiatus digitalis (at approximately 54.4 Ma) with the base of the Ypresian in the London Basin. Although the Ypresian definition would take priority under normal circumstances, a consensus has been reached to redefine the Eocene in recognition of the worldwide significance and correlatibility of stratigraphic features associated with the PETM. Redefinition of the Eocene, however desirable, nevertheless cannot proceed in a stratigraphic vacuum, and this paper is concerned with resolving the consequences of this action. To be made coincident with the CIE at approximately 55.5 Ma, the Ypresian/Thanetian boundary would have to be lowered by approximately 1 m.y., resulting in the inflation of the span of the Ypresian by 20% and a reduction of the span of the Thanetian by 30%. At the same time, the terminology of the strata in the leapfrogged interval would be thrown into total conflict with the literature, with the substitution of one widely used stage name for the other in the conflicted interval. On the other hand, to relocate the Paleocene/Eocene boundary without moving the stage boundaries would result in the upper third of the Thanetian falling within the Eocene, demolishing a century-old consensus. We propose that the destabilizing effect of the new boundary in the classic chronostratigraphy of western Europe can best be minimized with the introduction of a pre-Ypresian Stage, to encompass the orphaned upper Thanetian interval as the basal unit of the Eocene under a separate name. To this end, we suggest the reintroduction of the Sparnacian Stage, now that its original concept has been shown to correlate essentially with the interval between the CIE and the FAD of T. digitalis.

The formation includes two fossiliferous intervals: the upper, yielding about 12 mammalian species, and the lower, yielding one mammalian and one reptilian species. To constrain the temporal correlation of the Lingcha Formation faunas, we collected samples for isotopic and paleomagnetic analysis in three measured stratigraphic sections tied to the fossil sites. The isotopic and paleomagnetic results demonstrate that the transient carbon isotope excursion that marks the Paleocene-Eocene boundary as currently advocated is present in the upper Lingcha Formation. The fauna from the upper Lingcha Formation occurs within the excursion interval, and is thus of earliest Eocene age. It is correlative with the Wasatchian-0 faunal zone in the Bighorn Basin, Wyoming, to within approximately 10 (super 4) yr. Cluster analysis demonstrates compositional ties between the upper Lingcha fauna, the fauna from the Bumban Member of the Naran Bulak Formation, southern Mongolia, and the fauna from the Wutu Formation, northeastern China. These faunas form a cohort separated from earlier faunas by turnover at the ordinal and familial level, and from subsequent faunas by generic-level turnover. The discovery of a hyaenodontid in the Nomogen Formation of Inner Mongolia indicates that hyaenodontid creodonts may have appeared first in Asia and then spread to North America at the Paleocene-Eocene transition.

This paper presents detailed sedimentological background and paleoecological (i.e., environmental, climatic and vegetational) inferences drawn from the Dragon Glacier flora from Point Hennequin, King George Island. This leaf assemblage was originally thought to be an impoverished, postglacial Oligo-Miocene flora but now, based on new dating and botanical evidence, is considered to be a taxonomically diverse, middle Eocene preglacial flora that can be compared with other contemporaneous but relatively species depauperate middle Eocene floras from the same region. Eocene vegetation on King George Island grew in a sedimentary paleoenvironment characterized by fluvio-lacustrine deposition with a strong pyroclastic component providing evidence of volcanic activity set against a backdrop of gradual climatic change. The floral composition is comparable with modern South American rain forest vegetation growing under similar environmental conditions today and thus supports the Valdivian Model of disturbance-controlled successional vegetation.

Climate and ocean circulation fluctuated and affected marine and continental biota. Benthic foraminifera that occurred over a large part of the sea throughout the Paleocene were used as representatives of the marine biota, and spores and pollen of terrestrial plants as representatives of the continental biota, in order to study these environmental and biotic changes. Foraminifera and palynomorphs were studied in sedimentary sequences of Danian, Selandian, and Thanetian age. These sequences have regional names, and encompass the upper part of the Gankinskaya Stage, the whole Talitskaya Stage, and the lower part of the Lyulinvorskaya Stage. In the southwest part of the basin (the Omsk depression), upper Gankinskaya sediments (Maastrichtian to lowermost Danian) contain calcareous benthic foraminifera. Benthic foraminiferal assemblages suggest that sea level fell during the early Paleocene, so that the West Siberian basin shallowed significantly and decreased in size. During the earliest Danian, the basin in the Ust-Tym depression also became shallower, and "primitive" agglutinated foraminifera were dominant (e.g., Bathysiphon, Glomospira, Ammodiscus). Sea level rose during the Selandian boreal transgression (Talitskaya Stage), and agglutinated foraminifera occurred over large areas. In the Thanetian (represented by the uppermost Talitskaya and the base of the Lyulinvorskaya Stage) the basin again shallowed, and foraminifera became rare. The analysis of palynomorphs (spores and pollen) in allochthonous assemblages in marine sediments documents that an alluvial plain with lakes and bogs was situated on the southeast coast of the Paleocene West Siberian marine basin. The climate became more arid during the Danian and late Thanetian, with a pronounced phase of drying at the boundary between the Talitskaya and Lyulinvorskaya Stages (early Thanetian).

However, it is also less well understood than other such transitions. Here, we report the discovery of Eotitanops borealis, long considered the principal defining taxon for the beginning of the Bridgerian, from a classic late Wasatchian (Lostcabinian) fauna near the center of the northern Green River Basin. We argue that such a range extension should not be surprising given the relative rarity of this taxon in other geographic areas. This discovery implies that the beginning of the Bridgerian is in need of redefinition, but the selection of a different principal taxon (taxa) for this purpose is complicated by our poor understanding of the true first appearances of many traditionally Bridgerian taxa. We defer such redefinition and instead suggest several different migrational scenarios that might be considered as we continue to refine our understanding of this period of comparatively gradual climatic warming.

Apectodinium was present in the southern Tethys (Tunisia) by the late Paleocene (planktonic foraminiferal Subzone P4a), confirming earlier findings that the genus evolved in lower latitudes. Apectodinium abundance was frequent to dominant from the upper Paleocene to lower Eocene in the Tethys. The initial Eocene thermal maximum (IETM) at lower latitudes appears to be characterized by high percentages of Apectodinium, although it may not always have dominated assemblages. Other dinocyst genera with thermophilic preferences may be abundant during the IETM. At mid to high latitudes, Apectodinium has been sporadically recognized during the upper Paleocene. Nevertheless, the IETM at mid to high latitudes was still characterized by Apectodinium-dominated assemblages. Additional Apectodinium acmes occurred in the lower Eocene, although as yet it is unclear if these are globally isochronous. Intervals of Apectodinium-dominated assemblages are indicative of environmental conditions that were apparently markedly different to "normal background settings" of the late Paleocene-early Eocene. Sea surface temperature (SST) was probably the main control in distribution since Apectodinium acmes at mid to high latitudes seem to have occurred during intervals of highest SSTs, such as the IETM. In addition, the probable heterotrophic Apectodinium "blooms" were intricately linked to enhanced runoff and increased delivery of nutrients in surface waters, probably as a result of intensification of the weathering cycle and other possible specific oceanic conditions.

We document the paleo-environmental conditions in the basin using benthic foraminiferal and organic carbon data. Oxygen levels were lowest during the deposition of the middle part of the Kuma Formation, a time of relatively cool climate. We estimate the time of deposition and its duration as ranging from planktonic foraminiferal zones upper P11 through P14, and calcareous nannofossil zones CP13c to lowermost CP15 ( approximately 44-36.5 Ma). We argue that this large-scale storage of organic carbon over approximately 7 m.y. resulted from a complex interaction of tectonic and climatic factors, and that it may have influenced the global carbon budget in the ocean-atmosphere system. It probably was at least a contributing factor to the global cooling in the middle Eocene that led to the establishment of ice sheets on the Antarctic continent by the end of the Eocene.

Among them the most important and well studied is the Deccan Intertrappean flora. This flora is very interesting because it is marked by the presence of certain elements typical of Gondwana continents. Although the megafloral assemblages of Rajasthan and Kutch are not very rich, the presence of calcareous red algae and some coastal elements makes the floras important. The most notable feature of the Paleogene flora of India is the absence of Dipterocarpaceae, which is quite abundant during the Neogene. The general climate during the early Paleogene in India was warm and humid with plenty of rainfall. The land was covered with tropical evergreen to moist deciduous forests. Paleogeographers should take paleobotanical data into account in reconstructing the location of the fast moving Indian plate during the early Paleogene.

We determined the effects of elevated CO (sub 2) and water table position on methane emission and oxidation rates from plant-soil microcosms planted with a woody tree, Taxodium distichum, or an emergent aquatic macrophyte, Oiontium aquatirum. Experiments were conducted in replicate glasshouses (n = 2) at CO (sub 2) concentrations of either 350 or 700 ppmv. Plants were grown from seed and subjected to two water level depths, flooded (+5 cm above the soil surface) and non-flooded (-10 cm for T. distichum and -6 cm for O. aquaticum). Elevated CO (sub 2) increased whole-plant photosynthetic rates in both water table treatments. Methane emission rates increased by 62 to 69% in the T. distichum treatment and 27 to 29% in the O. aquaticum treatment. Whole-plant photosynthesis and biomass were strongly correlated with methane emissions (r (super 2) > or =0.75, P< or =0.01). This relationship provides evidence of a tight coupling between plant and microbial activity and suggests that similar relationships from other wetland studies measured at ambient CO (sub 2) can be extrapolated into the future. In the O. aquaticum, non-flooded treatment, methanotrophy consumed 14 and 22% (replicate glasshouses) of the methane produced in the ambient treatment compared to 29 and 36% in the elevated CO (sub 2) treatment. However, there was no significant methane oxidation detected in the flooded treatment. We concluded that woody and non-woody wetland ecosystems growing in a future CO (sub 2) -enriched atmosphere will emit more methane regardless of water table position, but the degree of stimulation will be sensitive to changes in water table position. particularly in forested wetlands.

The Colchester covers an area of more than 100, 000 km (super 2) , the Springfield covers 73,500-81,000 km (super 2) , and the Herrin spans 73,900 km (super 2) . Each has correlatives in the Western Interior Basin, such that their entire regional extent varies from 116,000 km (super 2) to 200,000 km (super 2) . Correlatives in the Appalachian Basin may indicate an even more widespread area of Desmoinesian peatland development, although possibly slightly younger in age. The Colchester Coal is thin, but the Springfield and Herrin Coals reach thicknesses in excess of 3 m. High ash yields, dominance of vitrinite macerals, and abundant lycopsids suggest that these Desmoinesian coals were deposited in topogenous (groundwater fed) to soligenous (mixed-water source) mires. The only modern mire complexes that are as wide-spread are northern-latitude raised-bog mires, but Desmoinesian Midcontinent paleomires were topogenous and accumulated within 10 degrees of the paleo-equator. The extent and thickness of Desmoinesian paleomires resulted from the coincidence of prime peat-forming factors, including a seasonally wet paleoclimate; cyclothemic transgressions and base-level rise above extensive, low-relief cratonic areas floored by vast, impermeable paleosols; broad floodplains along large rivers with a groundwater table high enough to hydrologically link peatlands and keep them wet; low, relatively uniform rates of tectonic subsidence; and accumulation in a basin surrounded by low relief, which led to minimal sediment input.

In this paper, we examine the taphonomy of a modern avian bone assemblage and test the relationship between ecological data based on avifaunal skeletal remains and known ecological attributes of a living bird community. A total of 54 modern skeletal occurrences and a sample of 126 identifiable bones from Amboseli Park, Kenya, were analyzed for weathering features and skeletal part preservation in order to characterize preservation features and taphonomic biases. Avian remains, with the exception of ostrich, decay more rapidly than adult mammal bones and rarely reach advanced stages of weathering. Breakage and the percentage of anterior limb elements serve as indicators of taphonomic overprinting that may affect paleoecological signals. Using ecomorphic categories including body weight, diet, and habitat, we compared species in the bone assemblage with the living Amboseli avifauna. The documented bone sample is biased toward large body size, representation of open grassland habitats, and grazing or scavenging diets. In spite of this, multidimensional scaling analysis shows that the small faunal sample (16 out of 364 species) in the prefossil bone assemblage accurately represents general features of avian ecospace in Amboseli. This provides a measure of the potential fidelity of paleoecological reconstructions based on small samples of avian remains. In the Cenozoic, the utility of avian fossils is enhanced because bird ecomorphology is relatively well known and conservative through time, allowing back-extrapolations of habitat preferences, diet, etc. based on modern taxa.

To investigate what adaptations may have allowed this lineage to persist with little or no morphological change for over 100 Myr, we analyzed both sedimentological and floral data from 51 latest Cretaceous to middle Miocene Ginkgo-bearing fossil plant sites in North America and northern Europe. The resulting data indicate that throughout the late Cretaceous and Cenozoic Ginkgo was largely confined to disturbed streamside and levee environments, where it occurred with a consistent set of other plants. These inferred habitats are surprising because the life-history traits of Ginkgo (e.g., slow growth rate, late reproductive maturity, extended reproductive cycle, large and complex seeds, large and slowly developing embryos) are counter to those considered advantageous in modern disturbed habitats. Many flowering plant lineages first appeared or became common in disturbed riparian habitats, and are inferred to have had reproductive and growth traits (e.g., rapid reproduction, small easily dispersed seeds, rapid growth) suited to such habitats. Paleoecological inferences based on both morphology and sedimentary environments thus support the idea that Ginkgo was displaced in riparian habitats by angiosperms with better adaptations to frequent disturbance.

New computer reconstructions, controlled by large beaches, isostatic rebound data, the margin of the Laurentide Ice Sheet, outlet elevations, and modern DEM topographic data, show how variable the size and depth of this lake were during its 4000 (super 14) C yr (5000 cal yr) history. Abrupt draw downs of 8-110 m in the lake surface occurred on at least 18 occasions, when new outlets were opened, reducing the extent of the lake and sending large outbursts of water to the oceans. These outbursts abruptly added 1600-9500 km (super 3) to the baseline overflow from the lake, and were routed to 3 different ocean basins: the Gulf of Mexico, Arctic, and North Atlantic. After each draw down, the lake transgressed back over the newly exposed lake floor, deepening the water everywhere to the south of the isobase that extended through the outlet. The final drainage of Lake Agassiz abruptly released 163,000 km (super 3) into the Hudson Bay basin and the North Atlantic. Three of the largest outbursts correlate closely in time with large delta (super 18) O excursions in the isotopic records of the Greenland ice cap, suggesting that those freshwaters impacted on thermohaline circulation and, in turn, on climate.

All five teeth are from the locality known as Sandberg, near Devinska Nova Ves (formerly known as Neudorf an der March), in the northwestern suburban part of Bratislava, Slovakia. The deposit in which the locality occurs is a transgressive sequence of nearshore marine sediments that are Upper Badenian in terms of the central Paratethyan marine biostratigraphy. The locality has also yielded a land mammal fauna of modest diversity that corresponds to earliest MN6 of the European land mammal biochronology. As earliest MN6, Griphopithecus suessi is among the earliest known hominids in Europe. Since Abel's description in 1902, the species has had a peripatetic taxonomic and nomenclatural history, but most recently was returned to Abel's genus Griphopithecus, which requires that it also be returned to Abel's species G. suessi, the type species of the genus.

Numerous claims of impact evidence for the Permo-Triassic mass extinction (251.6 Ma), the largest of the Phanerozoic mass extinctions, have generally been rejected, found wanting, or been difficult to reproduce. Despite this lack of repeatable support, considerable available evidence is consistent with an impact, including the rapidity of extinction, coincident carbon shift, and evident correlation between terrestrial and marine extinctions. However attractive the hypothesis, the coincidence with the Siberian flood basalts and the complex nature of the carbon shift are in conflict with an impact. The most intriguing possibility is that the greatest mass extinction of the Phanerozoic left signals very similar to the end-Cretaceous mass extinction but was produced by entirely Earth-bound processes. If true, this would tell us far more about the nature of ecosystems and how they fail than would identification of another impact. JF - Astrobiology AU - Erwin, Douglas H A2 - Kyte, Frank T.

This interpretation is counterintuitive with expectations that rapid global warming, which marks the Paleocene-Eocene boundary, would have led to intense vegetation turnover. In this review, data on Paleocene-Eocene pollen and spores are taken from published sources from four main regions in North America: (1) The U.S. Gulf Coast (paleolatitude 32 degrees N) (2) the eastern seaboard of Virginia (paleolatitude 39 degrees N) (3) the Bighorn and Powder River basins (paleolatitude 47 degrees N) and (4) the Canadian Arctic (paleolatitude 78 degrees N). This data set shows that there is no apparent latitudinal pattern to vegetation turnover in the early Eocene, but rather a strong distinction between the continental interior and the coastal areas. No one immigrant taxon characterizes the whole of North America and the coasts have a greater number of Eocene first occurrences than the continental interior. Immigrants can be classified as those that migrated from other continents, of which 40% have European Paleocene records, and those that immigrated from other regions in North America. Intracontinental immigration was exclusively from south to north and was restricted to coastal areas. The consequence of global warming was a complex vegetational response caused by the probable inability of many plants to disperse into North America.

We used shells from two water depths to constrain possible effects of freshwater influx. Assuming normal marine salinity we derived average temperatures for the winter of 16.9 degrees C and for the summer 22.5 degrees C at depths of 20-60 m, consistent with a subtropical climate. In contrast, Turritella spp., living at water depths of <20 m, record winter and summer temperatures of 23.4 degrees C and 28.5 degrees C, respectively, suggesting an unrealistically warm climate, especially in winter. The data indicate similar seasonal temperature ranges, 5-6 degrees C, at shallower as at greater depths. These estimates might reflect that Turritella did not calcify during the coldest months. Alternatively, they might indicate influx of local freshwater plumes. Positive delta (super 13) C values (2.7 per mil-3.8 per mil) of Turritella shells, however, suggest that conditions were close to or fully marine. The deeper-dwelling mollusks were probably not affected by local freshwater influx, but we cannot rule out that the entire southern North Sea had slightly reduced (1-3 psu) salinity. In that case, the estimated deeper water temperatures are too high by 1-3.5 degrees C. Even with these uncertainties, the isotopic data suggest that summer surface water temperatures were between 22 degrees C and 28 degrees C, and winter temperatures not colder than 13 degrees C. Denmark thus had a warm subtropical climate, as had other locations at these paleolatitudes in western Europe during most of the early Paleogene.

AN - 51362295; 2003-056978 AB - The lower Paleogene sequence in the Middle Povolzhie (Ulyanovsk-Saratov syncline) of Russia is dominated by a terrigenous-rich siliceous facies with abundant and well-preserved siliceous plankton. Calcareous microfossils are virtually absent. The diatom successions of the Sengiley diatomite are correlated to diatom assemblages of the Fur Formation (Denmark) and the Polosataya Formation (Kazakhstan), and are calibrated to calcareous nannofossil and dinocyst zonations. The Trinacria ventriculosa Zone, which is found in the lower part of the Sengiley diatomite (Kamyshin Formation), is age equivalent to the upper part of calcareous nannofossil zones NP8 through NP9a. The upper part of the Sengiley diatomite (Kamyshin Formation; Hemiaulus proteus Zone) can be correlated to the uppermost part of the Apectodinium augustum dinocyst Zone, which corresponds to the NP9b calcareous nannofossil Subzone, in which the globally observed negative carbon isotope excursion occurs. A major floral turnover in the upper third of the Sengiley diatomite is characterized by a succession of bioevents, including first appearances at generic and specific levels. Quantitative diatom analyses show pronounced compositional changes: (1) the decline of the meroplanktonic Pyxidicula group, typical of neritic conditions (2) the increase of the Paralia group, a marker for the proximity of the shoreline, and (3) a relatively high abundance of pelagic cosmopolitan species. Grain size analyses show an increase in terrigenous input in the upper part of Sengiley diatomite. The floristic and lithologic shifts indicate changes from stable, highly productive neritic conditions during a sea-level lowstand (Phase 1) to the onset of a transgression (Phase 2), which is followed by a highstand (Phase 3). The highstand phase coincides with enhanced exchange between the Tethys and the adjacent epicontinental seas. The diatom bioevents in Phases 2 and 3 in the Sengiley section are most probably coeval to the well-documented biotic changes of the Initial Eocene Thermal Maximum.

It shows resurgent volcanism of three distinct eruptive packages: the oldest probably of Late Pleistocene age, whose initial configuration was blown out by a massive explosion. The second cycle had intermittent eruptions between 1787 and 1832 AD, while the third cycle took place in two successive pulses between March-October, 1991 and December, 1994-May, 1995. The volcano is now in active fumarolic state. BV belongs to the SE Asian volcanic arc. It is believed that oblique convergence between the Indo-Australian plate and the Indo-Myanmar-Andaman-Sumatra block has developed Andaman-Java subduction regime and an easterly dipping Benioff zone along the western margin of this block. Neogene-Quaternary and the present day volcanism in this region is related to this easterly dipping Benioff zone. The 1991 eruption was initially of Strombolian type, later merging into Plinian style, while the 1994-95 eruption was all along Strombolian type with occasional phreatomagmatic explosions. The ratio of tephra to lava is nearly 2:1 during 1991 but the same is almost identical during the later pulse. The Pleistocene lava is olivine basalt. The lava of the 2nd cycle is also olivine basalt but significantly impoverished in MgO. The 1991 lava is olivine bearing basaltic andesite while that erupted during 1994-95 is again olivine basalt similar to that of the 2nd cycle. Lava erupted in all the three cycles was tholeiite being composed of a mixture of melt and silicate megacrysts of olivine (Fo (sub 87-70) ) with included chrome spinel (Cr (sub 2) O (sub 3) -8%), clinopyroxene (Mg (sub 48-44) Fe (sub 16-10) ) and plagioclase (An (sub 95-55) ). The melt contains phenocrysts of plagioclase (An (sub 69-57) ), augite and titanomagnetite (TiO (sub 2) -10%) set in a holocrystalline to aphanitic groundmass of Pl + aug + or - ol + gl + Fe-Ti oxides. No distinct mineralogical evolution is discernible with progress of time; the lava texture, however, points to prolonged partial crystallization in subterranean shallow magma chamber with intermittent perturbations. Silicate megacrysts occur either as distinct fragments or in coarse aggregates of troctolitic masses. It is suspected that the megacrysts are drawn from a primary source of troctolite forming the underbelly of the volcano. Lava chemistry closely compares with that of the Island arc tholeiite having been enriched in LREE and LILE and depleted in HFSE compared to N-type MORB. Sr isotope abundances reflect crustal contamination There is also possible lithospheric contamination of LREE in magma erupted during the early part of the eruptive phase in 1991. Since the later lavas are virtually least contaminated partial melts, it stands to reason that the plumbing system was by that time made open to the passage of magma; and that after the total evacuation of the latter, the thermal perturbation in the mantle, which caused this eruption after such a long gap has relaxed for the time being. The Barren magma is possibly generated from an E-type mantle source.

This chronology is correlated with monthly precipitation totals from January to June recorded at Saltillo some 55 km northwest of the collection site. The chronology was used to reconstruct winter-spring precipitation (January-June total) from 1782-2000. The reconstruction indicates large interannual, decadal, and multidecadal variability in winter-spring precipitation over Saltillo. This variability is vaguely apparent in the short and discontinuous instrumental record from 1950-1998, with January-June totals ranging from 15 to 310 mm, multiyear droughts, and a negative trend in January-June precipitation over the last 50 years. The reconstruction indicates that severe dryness was prevalent over a 24-year period from 1857-1880. This mid-19th century drought exceeds the duration of any droughts witnessed during the 20th century. However, three episodes of winter-spring dryness have prevailed in the Saltillo region after 1950, a much higher frequency of decadal drought than estimated over the past 219 years and aggravating the regional water supply problems associated with this booming manufacturing and ranching center.

Based on the new results and previous data, the late Cenozoic magmatism in the Baikal Rift System is considered to be an expression of four important thermal events in the lithosphere at 22-17 Ma, 16-12 Ma, 12-8 Ma, and 4-0 Ma. It is inferred that tectonic instability was first imparted at 22-17 Ma by a deep thermal event beneath the South Baikal basin, followed at 10-8 Ma by a similar event beneath the Khubsugul basin. These events resulted from tectonic stress associated with the Indian-Asian collision, 3000 km to the south, which was focused along a lithospheric-scale boundary, and in turn triggered upwelling of hot mantle material. Episodes of continued extension at 16-12 Ma and 4-0.6 Ma contributed to the development of the deep lake basins and also led to extensional faulting along the whole length of the rift system.

We estimate paleotemperatures for the last nearly equal 1.1 million years of the Cretaceous ( nearly equal 66.6-65.5 million years ago, Ma) by using fossil plants from North Dakota and employ paleomagnetic stratigraphy to correlate the results to foraminiferal paleoclimatic data from four middle- and high-latitude sites. Both plants and foraminifera indicate warming near 66.0 Ma, a warming peak from nearly equal 65.8 to 65.6 Ma, and cooling near 65.6 Ma, suggesting that these were global climate shifts. The warming peak coincides with the immigration of a thermophilic flora, maximum plant diversity, and the poleward range expansion of thermophilic foraminifera. Plant data indicate the continuation of relatively cool temperatures across the Cretaceous-Paleogene boundary; there is no indication of a major warming immediately after the boundary as previously reported. Our temperature proxies correspond well with recent rho CO (sub 2) data from paleosol carbonate, suggesting a coupling of rho CO (sub 2) and temperature. To the extent that biodiversity is correlated with temperature, estimates of the severity of end-Cretaceous extinctions that are based on occurrence data from the warming peak are probably inflated, as we illustrate for North Dakota plants. However, our analysis of climate and facies considerations shows that the effects of bolide impact should be regarded as the most significant contributor to these plant extinctions.

Eight species are recognized with three described as new. All species are described and diagnosed. The systematic history of the genus, including questions concerning its monophyly, is presented. Flight records are summarized with histogram plots, distributions are indicated by dot maps, and illustrated keys are provided for species identification. Floral association data and daily flight activity records are summarized, and a literature review of nesting biology is presented for four species (S. antiochensis, S. lusoria, S. oenotherae, S. texana). The new species are S. antiochensis (a potentially endangered species), S. danforthi, and S. potosi.

In an attempt to increase both population size and range, translocation sites were established beginning in the 1960's by moving squirrels from the natural range to sites outside the current range. Although translocations have served as the primary component of the DFS recovery program, there has been very little post-release examination of the genetics of the translocation sites. In this study, we developed ten microsatellite loci, screened the three polymorphic loci, and sequenced a 330 bp fragment of the mitochondrial control region in order to assess levels of genetic variation in natural and translocated regions of Delmarva fox squirrels and to compare them to Southeastern fox squirrels (S. n. niger). Although we found low levels of microsatellite polymorphism, there were no differences in heterozygosity between natural and translocated regions, or between Delmarva and Southeastern fox squirrels. We found high levels of polymorphism in the mitochondrial control region. Our patterns of haplotype diversity suggest incomplete lineage sorting of the two subspecies. In general, our data suggest that the current levels of genetic variation in the translocated sites are representative of those found in the natural population, and we encourage the continued use of translocations as a major component of Delmarva fox squirrel recovery.

A significant reduction of precipitation below current levels was almost certainly required to effect the changes observed. Core sediment characteristics indicate that permanent inundation of the Monte Oscuro basin with water occurred at about 10,500 super(14)C yr B.P. Pollen and phytolith records show that deciduous tropical forest expanded into the lake's watershed during the early Holocene. Significant burning of the vegetation and increases of weedy plants at ca. 7500 to 7000 super(14)C yr B.P. indicate disturbance, which most likely resulted from early human occupation of the seasonal tropical forest near Monte Oscuro and the development of slash-and-burn methods of cultivation.

One subject was measured both while she was pregnant and after she delivered a full-term, stillborn infant. Inactive-phase RMR within thermal neutrality (above 27.5 degree C) averaged 288.5+/-30.8 ml O sub(2)/hr; active- phase RMR within thermal neutrality averaged 416.3+/-60.9 ml O sub(2)/hr. These values are 74.6% and 107.6%, respectively, of the mammalian expected for animals of this body mass. During the inactive phase, metabolic rate increased an estimated 4.3% for every degree decline in temperature below 27.5 degree C. The RMR in Goeldi's monkey is similar quantitatively and qualitatively to those of other captive callitrichids that have been studied, with active-phase RMR being at or slightly above the mammalian expected, and inactive-phase RMR being significantly reduced. We propose that this circadian pattern of RMR is a consequence of small body size, and is not a specific metabolic adaptation within the Callitrichidae. Thus we predict that metabolic studies measuring both circadian phases in other small primates will also find this pattern of reduced RMR during the inactive phase. The inactive-phase RMR within thermal neutrality of the pregnant female was not different from that measured after the stillbirth, despite an almost 15% difference in body mass. During pregnancy, however, the female was more metabolically responsive to temperature below thermal neutrality, and had a lower upper critical temperature (i.e. was less tolerant of heat).

We evaluated the genetic management plan for the highly endangered black-footed ferret (Mustela nigripes) developed by the American Zoo and Aquarium Associations (AZA) as a part of the species survival plan (SSP). We contrasted data collected from five microsatellite loci to predictions from a pedigree-based kinship matrix analysis of the captive black-footed ferret population. We compared genetic diversity among captive populations managed for continued captive breeding or reintroduction, and among wild-born individuals from two reintroduced populations. Microsatellite data gave an accurate but only moderately precise estimate of heterozygosity. Genetic diversity was similar in captive populations maintained for breeding and release, and it appears that the recovery program will achieve its goal of maintaining 80% of the genetic diversity of the founder population over 25 years. Wild-born individuals from reintroduced populations maintained genetic diversity and avoided close inbreeding. We detected small but measurable genetic differentiation between the reintroduced populations. The model of random mating predicted only slightly lower levels of heterozygosity retention compared to the SSP strategy. The random mating strategy may be a viable alternative for managing large, stable, captive populations such as that of the black-footed ferret.

I tested the efficacy of basing breeding population surveys on the nest departure call (NDC). For a subset of point-count surveys designed to estimate the abundance and distribution of Swamp Sparrows in the coastal mid-Atlantic States, I surveyed singing males and (in a longer survey) the number of different females uttering NDCs. A set of 31 points was surveyed in early June and a subset of 21 in early July. The number of NDCs was well correlated with the number of singing males detected in the early season. The number of females giving NDCs was consistently smaller than the number of singing males. In part, this is because the detection distance for NDC is significantly shorter than for male song. However, even within a small fixed circular plot, more males were detected. Singing-male surveys provide more data over a shorter period of time and are appropriate for large-scale surveys. However, female NDCs provide an index of actual reproductive activity with no unmated birds included. Although a longer survey period is required, the surveys can be conducted throughout the day. It is suggested that female vocalizations related to nesting activity are more widespread than is generally appreciated and, when possible, should be used at least as complementary data to singing-male surveys.Original Abstract: El uso de llamadas de salida de los nidos para monitorear Melospiza georgiana Lambda as hembras de Melospiza georgiana hacen una potente serie de llamadas al dejar su nido durante la incubacion y la cria. Examine la eficacia de basar muestreos de las poblaciones reproductivas en estas 'llamadas al salir del nido' (NDC). Hice un muestreo de los machos cantando y (en un estudio mas largo) el numero de diferentes hembras produciendo NDCs para una subrutina de muestreos por conteos de puntos disenados para estimar la abundancia y distribucion de Melospiza georgiana en la costa central del Atlantico. Se muestreo un grupo de 31 puntos a principios de junio y otro grupo de 21 a principio de julio. El numero de NDC fue bien correlacionado con el total de machos cantando detectados al principio de la temporada. El numero de hembras produciendo NDCs fue consistentemente menor que el numero de machos cantando. Esto se debe en parte, a que la distancia en detectar los NDCs es significativamente menor que para detectar la cancion de los machos. Sin embargo, aun dentro de una parcela de un diametro fijo pequeno, se detectaron mas machos. Los muestreos de machos proveen mas datos sobre un periodo mas corto de tiempo y son apropiados para muestreos a larga escala. Sin embargo, los NDCs de las hembras proveen un indice de la actividad reproductiva actual sin incluir aves sin pareja. Aunque se requiere un periodo de muestreo mayor, los muestreos se pueden conducir a traves del dia. Se sugiere que las vocalizaciones femeninas asociadas a la actividad de anidaje son mas abundantes de lo que se aprecia generalmente y debian ser utilizadas por lo menos como datos complementarios a los muestreos de machos.

Mate-searching females preferentially approach these structures and subsequently mate with structure builders. Here we show that the preference for structures is not species-specific and argue that it may not have evolved for mate choice. When not near burrows, many species of fiddler crabs approach and temporarily hide near objects, suggesting that hoods and pillars may attract females because they elicit this general predator-avoidance behavior. To test this sensory trap hypothesis we individually released female U. musica, U. beebei and Uca stenodactylus, a non-builder, in the center of a circular array of empty burrows to which we added hoods and pillars and then moved a model predator toward the females. All species ran to structures to escape the predator and the two builders preferred hoods. Next, we put hood replicas on male U. beebei burrows and pillar replicas on male U. musica burrows. When courted, females of both species preferentially approached hoods as they did when chased with a predator. However, males of both species with hoods did not have higher mating rates than males with pillars perhaps because hoods block more of a male's visual field so he sees and courts fewer females. Sexual selection may often favor male signals that attract females because they facilitate general orientation or navigation mechanisms that reduce predation risk in many contexts, including during mate search.

Models of sex-specific mate-searching behavior predict single-sex searching, but the factors that determine which sex searches are not understood. In this study, we examine the effects of density and predation risk on mate-searching behavior in the fiddler crab Uca beebei. U. beebei is one of the few fiddler-crab species in which both sexes search for mates. In a field experiment conducted in Panama, we manipulated crab density and perceived predation risk in replicate plots. Females searched more and males searched less at high densities. At high levels of perceived predation risk, both sexes similarly reduced their search rates. Observations of plots that naturally varied in crab density show that females were more likely to search for mates in areas of higher density, where there were more males. Females may preferentially search for mates in high-density areas because the abundance of nearby burrows, into which they can run to escape predators, decreases their costs of searching and because the abundance of males and male burrows facilitates comparisons and thus may increase their benefits from searching. Males at high densities decrease their mate-searching rate perhaps in response to the increase in female searching and to the corresponding increase in the intensity of their competitors' mate-attraction signals.

We analysed variation in the mitochondrial DNA (mtDNA) control region for representatives of all three Eld's deer subspecies to gain a better understanding of the genetic population structure and evolutionary history of this species. A phylogeny of mtDNA haplotypes indicates that the critically endangered and ecologically divergent C. eldi eldi is related more closely to C. e. thamin than to C. e. siamensis, a result that is consistent with biogeographic considerations. The results also suggest a strong degree of phylogeographic structure both between subspecies and among populations within subspecies, suggesting that dispersal of individuals between populations has been very limited historically. Haplotype diversity was relatively high for two of the three subspecies (thamin and siamensis), indicating that recent population declines have not yet substantially eroded genetic diversity. In contrast, we found no haplotype variation within C. eldi eldi or the Hainan Island population of C. eldi siamensis, two populations which are known to have suffered severe population bottlenecks. We also compared levels of haplotype and nucleotide diversity in an unmanaged captive population, a managed captive population and a relatively healthy wild population. Diversity indices were higher in the latter two, suggesting the efficacy of well-designed breeding programmes for maintaining genetic diversity in captivity. Based on significant genetic differentiation among Eld's deer subspecies, we recommend the continued management of this species in three distinct evolutionarily significant units (ESUs). Where possible, it may be advisable to translocate individuals between isolated populations within a subspecies to maintain levels of genetic variation in remaining Eld's deer populations.

Using constant-power sap flow gauges, we measured transpiration from Quercus myrtifolia Willd., the dominant species of the Florida scrub-oak ecosystem, which had been exposed in situ to elevated C sub(a) (350 mu mol mol super(-1) above ambient) in open-top chambers since May 1996. Elevated C sub(a) reduced average transpiration per unit leaf area by 37%, 48% and 49% in March, May and October 2000, respectively. Temporarily reversing the C sub(a) treatments showed that at least part of the reduction in transpiration was an immediate, reversible response to elevated C sub(a). However, there was also an apparent indirect effect of C sub(a) on transpiration: when transpiration in all plants was measured under common C sub(a), transpiration in elevated C sub(a)-grown plants was lower than that in plants grown in normal ambient C sub(a). Results from measurements of stomatal conductance (g sub(s)), leaf area index (LAI), canopy light interception and correlation between light and g sub(s) indicated that the direct, reversible C sub(a) effect on transpiration was due to changes in g sub(s) caused by C sub(a), and the indirect effect was caused mainly by greater self-shading resulting from enhanced LAI, not from stomatal acclimation. By reducing light penetration through the canopy, the enhanced self-shading at elevated C sub(a) decreased stomatal conductance and transpiration of leaves at the middle and bottom of canopy. This self-shading mechanism is likely to be important in ecosystems where LAI increases in response to elevated C sub(a).

This study provided a cross validation of these two different techniques for measuring NEE. Unique characteristics of the comparison were that the measurements were made simultaneously, in the same stand, with large replicated chambers enclosing a representative portion of the ecosystem (75 m super(2), compared to approximately 1-2 ha measured by the eddy covariance system). The value of the comparison was greatest at night, when the microclimate was minimally affected by the chambers. For six of the 12 measurement periods, night NEE sub(O) was not significantly different to night NEE sub(E), and for the other periods the maximum difference was 1.1 mu mol m super(-2)s super(-1), with an average of 0.72 plus or minus 0.09 mu mol m super(-2)s super(-1). The comparison was more difficult during the photoperiod, because of differences between the microclimate inside and outside the chambers. During the photoperiod, air temperature (T sub(air)) and air vapour pressure deficits (VPD) became progressively higher inside the chambers until mid-afternoon. In the morning NEE sub(O) was higher than NEE sub(E) by about 26%, consistent with increased temperature inside the chambers. Over the mid-day period and the afternoon, NEE sub(O) was 8% higher that NEE sub(E), regardless of the large differences in microclimate. This study demonstrates both the uses and difficulties associated with attempting to cross validate NEE measurements made in chambers and using eddy covariance. The exercise was most useful at night when the chamber had a minimal effect on microclimate, and when the measurement of NEE is most difficult.

The so-called petrologic method, used to evaluate syn-eruptive melt degassing, is expanded by also considering the role of a pre-emptive gas phase. It is shown that more than 90% of the atmospheric sulfur loading may come from release of the pre-emptive gas phase during eruptions of intermediate to silicic magmas at subduction-related volcanoes. In contrast, the role of a pre-emptive gas phase may be much less important in more mafic magmas empted in other tectonic settings. Bulk sulfur contents are weakly (spreading-ridges and hot spots) to non-correlated (subduction-zones) with bulk-rock composition. With the exception of some persistently active volcanoes, bulk sulfur contents generally do not exceed 0.5 wt %. The sulfur yields are positively correlated with mass of erupted magma, but the dispersion in sulfur emission for a given empted mass increases progressively as the empted mass decreases. The sulfur yields of single emptive events retrieved from this improved petrologic method are shown to closely agree with independent estimates obtained from analysis of ice cores, optical-depth measurements, and remote-sensing spectroscopic techniques (TOMS and COSPEC).

Data include both previously published and newly reported coral and peat dates. With the elevations of corals restricted to positions below sea level and those of peats to intertidal and higher levels, a curve bracketed by corals below and peat above effectively delineates the positions of a rising Holocene sea. From 3-11 ka, the corrected curve shifts progressively to older calibrated ages, reaching an ~61-kyr increase at -21 m MSL (mean sea level). Elevations and calibrated ages of samples from each locality in the wider Caribbean region constitute an important database for future refinement with glacio-hydro-isostatic elevation corrections from 3-D Earth models. In future studies of the history of western Atlantic coral reefs, scientists will be able to relate calibrated radiocarbon dates to this sea-level curve to determine paleo water depths and rates of sea-level rise.

DIC was measured over diurnal cycles in different seasons in a marsh tidal creek and at the junction of the creek with the adjacent Pamunkey River. In the creek, DIC concentrations around high tide were controlled by the same processes affecting whole-estuary DIC gradients. Near low tide, DIC concentrations were 1.5-5-fold enriched relative to high tide concentrations, indicating an input of DIC from the marsh. Similar patterns (although dampened in magnitude) were observed at the creek mouth and indicated that DIC was exported from the marsh. Marsh pore-water DIC concentrations were up to 5 mmol L super(-1) greater than those in the creek and suggested a significant input of sediment pore water to the creek. A model of tidal marsh DIC export showed that, on a seasonal basis, DIC export rates were influenced by water temperature. The composition of exported DIC averaged 19% dissolved CO sub(2) and 81% HCO super(-) sub(3) and CO super(2) sub(3) super(-). Although CO sub(2) can be lost to the atmosphere during transit through the estuary, DIC in the form of carbonate alkalinity is subject to export from the estuary to the coastal ocean. When extrapolated to an estuarywide scale, the export of marsh-derived DIC to the York River estuary explained a significant portion (47 plus or minus 23%) of excess DIC production (i.e., DIC in excess of that expected from conservative mixing between seawater and freshwater and equilibrium with the atmosphere) in this system. Therefore, CO sub(2) supersaturation, by itself, does not indicate that an estuary is net heterotrophic.

Many preferred game species consume flowers, fruit, seeds and/or leaves, and these interactions will cause their harvest to ramify through forests. Three related issues will determine how severely the harvest of forest vertebrates influences the plant community. First, the types of species selected by hunters and the intensity of the harvest will determine which vertebrates are removed and which remain. Second, the possible presence of ecologically similar, non-game species able to expand their activities to fulfill the ecological role of heavily exploited species will determine how severely the harvest disrupts ecological relationships between the community of forest vertebrates and the community of forest plants. Finally, hunters will alter plant species composition if the harvest of vertebrates differentially affects mutualists or pests of particular plant species. Hunters will also alter plant diversity if the harvest of vertebrates disrupts ecological mechanisms that permit plant species to coexist. I examine hunter selectivity, the intensity of the hunt, possible compensation by non-game species, and the types and strengths of interactions among game species and plants for tropical forests to determine when and where these outcomes occur.

People living beyond the age of 100 are 16 times more common here than elsewhere in the world, and three times more common than in the US as a whole. Numerous theories about this proliferation abound: the fresh air, independent lifestyles, clean living, religious commitments, and musical involvement have all been advanced as reasons for long lives. Oddly, as a whole, citizens of this province are not particularly healthy: the traditional diet is high in fried foods, exercise is minimal, smoking levels are high, and obesity is common. An analysis of Canadian census data indicates that the high proportion of centenarians may be attributed to a genetic component, traced to early German and French settlers, many of whom married into the same families. Research on sibling sets suggests similarities in DNA strands along chromosome no. 4.

Research will be conducted through dives, robotics, and radar tracking. One aspect of the global research is the tagging and tracking of Pacific bluefin tuna, conducted by researchers at the Tuna Research and Conservation Center, Monterey, CA. This commercially important species contributes to the $3 billion tuna industry, and is prized as sushi in Japan. Although populations of this species are relatively stable, tuna in the Atlantic are more vulnerable. The global census of marine life was launched by the Alfred P.

Short-term studies have shown that crop-canopy Ca undergoes substantial diurnal and seasonal variations as compared to Ca values measured several meters above plant canopies in well mixed conditions. Whether these canopy Ca patterns measured in crops also apply to wetland plant canopies and over long periods of time remains largely unknown. The first objective of this study was to analyze the consistency of short- and long-term Ca patterns in salt marsh canopies over a 10-year period. The second objective was to assess the impact of these canopy Ca patterns on simulated ecosystem productivity. In this study, we used Ca data collected from 1990 to 2000 in salt marsh canopies of the Chesapeake Bay, Maryland. The possible effects of short- and long-term canopy Ca patterns on plant productivity were simulated with a mechanistic model specifically adapted to the Scirpus olneyi vegetation of the salt marsh ecosystem. The annual average of daytime canopy Ca of a brackish marsh community rose by a significant (P < 0.01) 1.55 mu mol CO sub(2) mol super(-1) year super(-1) between 1990 and 2000, which parallels the atmospheric records of Mauna Loa over the same period of time. Annual Ca averages displayed some variability around this trend, which were highly correlated with the year-to-year variation in aboveground plant biomass (r super(2) = 0.83, P < 0.001). Therefore, our study demonstrated that aboveground plant biomass is the main driver for inter-annual canopy Ca fluctuations. Daytime canopy Ca displayed maximum values in May and September and minimum values in July, with an amplitude of about 20 mu mol CO sub(2) mol super(-1). The amplitude of the diurnal Ca cycle measured at the wetland appeared similar to that of North American agricultural ecosystems, exceeding 100 mu mol CO sub(2) mol super(-1) in July and August and characterized by a sharp drop in the CO sub(2) concentration shortly after dawn. Model simulations suggested that the increase in canopy Ca from 1990 to 2000 resulted in a substantial increase in Scirpus gross plant productivity (GPP) of 0.31% per year, which confirms that plant ecosystem simulations need to consider the actual increase in canopy Ca when the simulated time period exceeds a few years. Forcing the model with the measured diurnal Ca pattern increased the simulated net plant productivity (NPP) immediately after dawn and decreased it for the rest of the daytime period, which resulted in a simulated net NPP decrease of about 5% over the growing season.

W. Cameron AN - 52007738; 2003-024490 AB - In this interview, Alastair Cameron recounts how he started his career as a nuclear physicist but taught himself astrophysics after he read a paper that required an astrophysical explanation for the presence of technetium in red giant stars. Subsequently, as new analytical data became available, he periodically updated the Suess-Urey tables of elemental abundances to enhance the value of the systematic approach they provided to understanding individual processes of nucleosysthesis. Since many of these new data were based on analyses of carbonaceous chondrites, he taught himself meteoritics. In recent decades, Cameron has focused his research interests on problems such as the provenance of certain components of meteorites (calcium-aluminum-rich inclusions, FUN (fractionated and unknown nuclear) anomalous inclusions, amoeboid olivine aggregates, and presolar grains) that he believes to have formed in the supernova envelope prior to formation of the solar nebula, the origin of chondrules in the primitive solar nebula, and the origins of the solar system and of the Earth-Moon system. To investigate these subjects he has pioneered the use of advanced computer technology to make lengthy calculations of nucleosysthesis in complicated networks. After teaching courses and advising graduate students at several research institutes and colleges, Cameron served as a Professor of Astronomy at Harvard University from 1973 to 1997 when he was appointed to the Donald H. Menzel Research Professorship of Astrophysics. In 1994, The Meteoritical Society honored him with the Leonard Medal at its meeting in Prague, the Czech Republic.

A sudden explosion like a cannon shot followed by fierce whistling sounds frightened people over a wide area. Some saw a fiery body falling from the sky; others said it was dark and smoky. The ground shook when the stone plunged into the soil making a hole nearly a meter deep. The Abbe Domenico Troili collected eyewitness reports, examined the stone, and reported the presence of marchesita, an old name for pyrite. A century later, this mineral, which proved to be iron sulfide (FeS), was named "troilite" in his honor. Troili's description is unquestionably that of a meteorite fall, and therefore some scientists have argued that it is Troili, rather than Ernst F. F. Chladni, to whom we should give credit as the first person to record the fall of a stone from space. However, Troili, himself, had no such an idea; he wrote that a subterranean explosion had hurled the stone high into the sky from a vent in the Earth. He stoutly defended this explanation against his opponents, including the Bishop of Modena, who believed that the stone had been hurled aloft by a bolt of lightning. Both hypotheses reflect a conviction, held well into the nineteenth century, that any rocky objects that fall from the sky must originate on the Earth or in the atmosphere. In 1794, Chladni calculated that meteors and meteoritic fireballs course down the sky at such extremely high velocities that the bodies forming them must originate in space. He listed all the falls that he found credible in historic records. Partly through his efforts, meteorites had gained widespread acceptance by 1803, but the idea of their origin in space had not. For the next half century many scientists continued to argue that meteorites either consolidate in the upper atmosphere or are ejected by volcanoes on the Moon. Recent efforts to transfer honors from Chladni to Troili for being the first to describe meteorites as bodies falling from space are unwarranted.

There, he worked on problems relating to uranium-helium ages of iron meteorites. A year later, Wanke moved with Paneth to the Max-Planck-Institut fur Chemie at Mainz in Germany. He continued meteorite research but also conducted experiments to measure noble gases in the stratosphere, a project that brought him to America in 1956 where he first met Professor Harold C. Urey, with whom he formed a lasting friendship. After Paneth's early death in 1958, Wanke remained at the Institute in Mainz and pursued research on topics such as the isotopic compositions of cosmogenic noble gases in iron meteorites and the abundances of primordial rare gases implanted by solar wind particles in brecciated stony meteorites. In 1969, Wanke was appointed to fill Paneth's position as a director of the Max-Planck-Institut fur Chemie just in time for him to lead a wide spectrum of research projects on the lunar rocks and soils. From the geochemical evidence these studies provided, he theorized on the formation of the Moon by the giant impact hypothesis, and proposed a two-component model for the cosmic composition of the Earth's mantle. His group also investigated the isotopic chemistry of martian meteorites and its bearing on the origin and evolution of Mars, which he viewed as a cored planet that underwent early differentiation without subsequent convective homogenization. In 1980, the Meteoritical Society awarded the Leonard Medal to Heinrich Wanke for his numerous contributions of fundamental importance to meteoritics and planetary science.

Born and raised in New Zealand, Ross majored in chemistry at Canterbury College in Christchurch. While there, he took a course in geology and was strongly tempted to change his major, but he resolved the problem by becoming a geochemist. For his doctoral studies, Ross joined Mason at Indiana University where he learned the basics of trace element analysis on the emission spectrograph. Subsequently, he set up emission spectrographic laboratories and used them to pursue his research at Oxford University and the University of Cape Town. As techniques became more sensitive, he set up a spark-source mass spectrograph at the Australian National University in Canberra. Ross always has retained an interest in terrestrial rocks, but he is most widely known for his investigations of tektites and lunar rocks. He became one of the earliest and strongest advocates of tektites as molten terrestrial sediments sent aloft by high-energy impacts. As a member of the preliminary examination team that analyzed the samples returned by the Apollo missions, Ross gained an intimate knowledge of lunar chemistry and petrology and wrote three books about the Moon. He also has written a book about the chemical evolution of the solar system, a topic on which such rapid progress was made in 10 years that his second edition is practically a different book from the first one. Ross has written Destiny or Chance, a philosophical consideration of the likelihood that as sentient beings we may well be alone in the universe. Ross served as the president of The Meteoritical Society in 1989 and 1990, and at its annual meeting in Dublin, Ireland, in 1998, the Society presented him with its Leonard Medal.

Houtermans, first in Gottingen and then in Bern, Switzerland, he began his career as what he calls a low-level gas counting man, specializing in tritium ( (super 3) H). In 1954 he accepted an invitation from Professor Willard F. Libby to run his gas-counting laboratory at the University of Chicago. Begemann spent 3 years there during which he traced the distribution in the world's atmosphere and waters of tritium from two sources, natural cosmic radiation and the detonation of the first thermonuclear device. During his time at Chicago he was drawn into Harold C. Urey's group of scientists studying meteorites. Begemann found that he could measure tritium in meteorites, and by coupling his values with those of (super 3) He, he and his collaborators initiated a new branch of meteoritics by determining the first cosmic-ray exposure age of a meteorite--Norton County, which fell in 1947. In 1957, Begemann joined the group led by Friedrich A. Paneth at the Max-Planck-Institut fur Chemie at Mainz, Germany, where he continued his studies of gas isotopes for the remainder of his career. His research led to the discovery of primitive noble gases in the diamond-graphite aggregates in ureilites, where their presence in presumably deep-seated igneous rocks still remains to be explained. With the advent of the Apollo missions, Begemann extended his studies to the lunar rocks and soils in an effort to learn as much as possible about the interaction of solids with the space environment. He also became heavily involved in measuring the s-process isotope abundance patterns of medium-heavy chemical elements as they occur in interstellar grains. In 1995 at the meeting in Washington, D.C., The Meteoritical Society presented Friedrich Begemann with the Leonard Medal for his contributions to our understanding of the radiation encountered by bodies as they orbit through space.

Brian Mason AN - 52005469; 2003-024488 AB - In this interview, Brian Mason describes the sudden awakening of his interest in meteorites during his student days at Canterbury College in New Zealand when he read a paper on the cosmic abundances of the elements by Victor M. Goldschmidt. Subsequently, he won a scholarship for graduate study abroad and wrote to Goldschmidt asking if he could do a thesis with him in Norway. Shortly after he began his research in Oslo, he fled the city, ahead of the German invasion of Norway, and completed his doctorate in Stockholm with a thesis on the iron-manganese minerals of the Langban Mine. After the war he taught for 3 years at Canterbury College where he gave courses on mineralogy and geology (into which he inserted lectures on geochemistry) and led students in extensive field studies. In 1947, Mason accepted a professorship of mineralogy at Indiana University. While there, he wrote the landmark book, Principles of Geochemistry, which appeared in 1952. The following year he moved to New York City where he served as the Curator of Minerals at the American Museum of Natural History and an adjunct professor at Columbia University. He became fascinated with the museum's meteorite collection and discussed meteorites in his lectures, which inspired some of his outstanding students to enter the field. During a sabbatical year he spent as a Fulbright Professor in Japan, he gave an advanced level seminar on meteorites and based his book, Meteorites, on his lecture notes. Mason developed a rapid method of optically classifying chondritic meteorites that he applied to major collections in many countries, thus enabling curators to replace uninformative labels such as "stone" or "chondrite" with species names, and to recognize which of their meteorites were rare types demanding serious study. In 1965 he moved to the Smithsonian Institution in Washington, D.C. where he remained for the rest of his career. Early in 1968, he collected specimens from the spectacular fall of the Allende meteorite in Mexico, which proved to be a carbonaceous chondrite containing rare types of inclusions enriched in calcium and aluminum. His analyses showed how these inclusions could be divided into groups on the basis of their differing rare earth element patterns. Mason's studies of Allende continued while he investigated lunar samples returned by the Apollo missions and coauthored a book on them. Beginning in the latter 1970s, he applied his rapid classification of stony meteorites to the large numbers of specimens collected each year by U.S. teams on the Antarctic ice sheet. In 1992 he capped his career with a biography of Victor M. Goldschmidt. In recognition of his many fundamental contributions, The Meteoritical Society honored Brian Mason with its Leonard Medal at its meeting in 1972 at the University of Chicago.

High levels of pollution were found in the entire region with averages of 18.9 and 71.3 ppb in coral skeletons and sediments respectively. Significantly higher contamination was found in Panamanian corals (21.4 ppb) while compared to Costa Rican reef sediments (85.9 ppb). Hg from several processes and non-point sources (e.g., erosion, runoff, flooding, mining, overuse of agrochemicals, industrial waste, ports, and refineries) may have affected the entire region. The widespread observed distribution suggests that Hg is being carried along long distances within the region due to its high concentrations found in "pristine" reefs. Forest burning and colonial mining residues may be considered as possible contamination factors.

The purpose of this study was to compare Schinus water uptake patterns to those of four native species in a disturbed previously farmed area versus a native pineland community. Although neither of the study sites was flooded, soils in both sites were saturated with water at the end of the wet season. Isotopic analysis of stem water showed that almost all the native species in both sites showed a seasonal change in plant water uptake; plants utilized mainly groundwater during the dry season but shifted to a high proportion of soil water during the wet season. In the pineland community, Schinusshowed no seasonal shift in water uptake source. In the disturbed community, however, Schinus was not isotopically distinct from the native species with regard to water source. Despite greater soil water availability in the wet season, predawn water potentials were significantly lower in the wet than in the dry season for native species at both sites. The counterintuitive decrease in water potentials during the wet season in both study sites could be the response of native plants to root flooding. Predawn water potentials of Schinus in both study areas however, remained constant across seasons. Predawn and noontime water potential differences were smaller in Schinus than in the native species at both sites during the wet season, but this pattern was found only in the disturbed area during the dry season. Schinus was most likely less affected by seasonality and more tolerant of root flooding than the native species studied.

Methane oxidation was measured in situ over a 16-month period with bi-monthly applications of the inhibitor CH sub(3)F.

Methane oxidation rates were linearly related to gross CH sub(4) emissions on both sites (r super(2) = 0.96), demonstrating the process was CH sub(4)-limited. This interpretation is consistent with the fact that the apparent activation energies for the potential CH sub(4) production and oxidation differed by <4 kJ mol super(-1). Apparent activation energies calculated from field emissions data were also similar for the two processes. The high CH sub(4) oxidation efficiency on these sites may be attributed to relatively low rates of methane production, a deep oxidizing zone (5-10 cm), and low cover of understory vegetation capable of CH sub(4) transport. If our results are typical of forested wetlands, CH sub(4) oxidation efficiency in forested wetlands will not change in response to soil warming.

Seed dispersal was greatest when water depth was greatest, which occurred during the new moon. Seeds of buoyant species with smaller seeds required less water for dispersal than large seeded species. Submerged objects reduced the distance dispersed but not the probability of dispersal.

The reproductive cycle of the sea star was studied in Isla Solarte, from February 2000 to February 2001. In total, 4,818 sea stars were recorded with a mean density of 149.7 ind. ha super(-1), and a population of over 7 million was estimated for the archipelago. O. reticulatus was absent in ca. 50% of the evaluated areas, possibly due to high runoff and sedimentation; highest density was observed in an intermediate-runoff regime (255 ind. ha super(-1)). About 45% of the population was found in substrata dominated by seagrass (Thalassia testudinum) and coarse, calcareous sand, 51% occurred in habitats where coral reef patches were mixed with seagrass, and 4% exclusively on coral reefs. The average size, based on the major radius, was 9.5 cm (3-21 cm), with a population structure composed of ca. 83% juveniles and 17% adults. The average reproductive size, measured as major radius, was 15 cm, and the minimum was 7 cm. Both males and females with a maximum stage (IV) of gonad development were observed throughout the year. The gonad index showed three peaks of maximum reproductive activity, which is not comparable to studies from other localities. The reproductive cycle did not seem to be related to water temperature, which ranged from 27 degree C to 30 degree C, but may respond more closely to changes in local rainfall. This relationship was not statistically significant based on this 1-year study. These data provide a useful baseline for management of local populations in the face of an increasing harvest for the aquarium trade and as souvenirs.

In order to study behaviour and to examine patterns of paternity and relatedness between different harem groups, we developed 14 microsatellite loci from two different enriched genomic libraries. We screened 125 individuals from two different bat colonies and found that polymorphism ranged from five to 13 alleles. Heterozygosity ranged from 63 to 95%. The primers amplified across 14 bat species, indicating their potential utility for population-level studies in several closely related bat species.

Based on morphological studies, it was thought that a single species (Pegoscapus hoffmeyeri) pollinated this fig. However, our data revealed the presence of two coexisting cryptic species. Several diagnostic microsatellite markers may be used to distinguish these two cryptic species. The new microsatellites can be used across a wide range of fig-pollinating wasp species for both evolutionary and population genetic studies.

AN - 72685742; 12437064 AB - In 1996, the Smithsonian Tropical Research Institute and the Republic of Panama's Environmental Authority, with support from the United States Agency for International Development, undertook a comprehensive program to monitor the ecosystem of the Panama Canal watershed. The goals were to establish baseline indicators for the integrity of forest communities and rivers. Based on satellite image classification and ground surveys, the 2790 km2 watershed had 1570 km2 of forest in 1997, 1080 km2 of which was in national parks and nature monuments. Most of the 490 km2 of forest not currently in protected areas lies along the west bank of the Canal, and its management status after the year 2000 turnover of the Canal from the U.S. to Panama remains uncertain. In forest plots designed to monitor forest diversity and change, a total of 963 woody plant species were identified and mapped. We estimate there are a total of 850-1000 woody species in forests of the Canal corridor. Forests of the wetter upper reaches of the watershed are distinct in species composition from the Canal corridor, and have considerably higher diversity and many unknown species. These remote areas are extensively forested, poorly explored, and harbor an estimated 1400-2200 woody species. Vertebrate monitoring programs were also initiated, focusing on species threatened by hunting and forest fragmentation. Large mammals are heavily hunted in most forests of Canal corridor, and there was clear evidence that mammal density is greatly reduced in hunted areas and that this affects seed predation and dispersal. The human population of the watershed was 113 000 in 1990, and grew by nearly 4% per year from 1980 to 1990. Much of this growth was in a small region of the watershed on the outskirts of Panama City, but even rural areas, including villages near and within national parks, grew by 2% per year. There is no sewage treatment in the watershed, and many towns have no trash collection, thus streams near large towns are heavily polluted. Analyses of sediment loads in rivers throughout the watershed did not indicate that erosion has been increasing as a result of deforestation, rather, erosion seems to be driven largely by total rainfall and heavy rainfall events that cause landslides. Still, models suggest that large-scale deforestation would increase landslide frequency, and failure to detect increases in erosion could be due to the gradual deforestation rate and the short time period over which data are available. A study of runoff showed deforestation increased the amount of water from rainfall that passed directly into streams. As a result, dry season flow was reduced in a deforested catchment relative to a forested one. Currently, the Panama Canal watershed has extensive forest areas and streams relatively unaffected by humans. But impacts of hunting and pollution near towns are clear, and the burgeoning population will exacerbate these impacts in the next few decades. Changes in policies regarding forest protection and pollution control are necessary.

This symposium combined presentations from ten scientists whose question-driven research focuses on testing hypotheses about patterns and processes in biogeography in both vertebrate and invertebrate animals and including marine, terrestrial, and freshwater systems. The papers gathered here cover the breadth of the presentations. By explicitly seeking to combine marine and terrestrial workers into a single symposium we hoped that the different patterns and processes that predominate in major biomes and the different assumptions made by the workers in those areas would be highlighted.

However, consistent captive propagation of the cheetah, a prerequisite for establishing a self-sustaining population, has not been accomplished so far. This study examined the effect of a husbandry regimen commonly used in ex situ facilities on female cheetahs. Although generally solitary in the wild, zoos frequently house cheetahs in pairs or groups. Using non-invasive hormone monitoring and quantitative behavioural observations, we studied the impact of such enforced social conditions on behaviour and ovarian/adrenal activity. Eight female cheetahs were evaluated for two consecutive 6-month periods, first while maintained in pairs and then as individuals. Subsequently four females were regrouped into two new pairs and monitored for another 6 months. Females in five of six pairings demonstrated prolonged anoestrus and displayed agonistic behaviours. After pair separation all females rapidly resumed oestrous cyclicity. Females in the sixth pair continued cycling throughout the year while consistently displaying affiliative grooming and no agonistic behaviours. Faecal corticoid patterns varied significantly among individuals, but appeared unrelated to behavioural or ovarian hormone patterns. Thus, data appear to indicate that same-sex pair-maintenance of behaviourally incompatible female cheetahs may lead to suppressed ovarian cyclicity. This suppression appears linked to agonistic behaviours but not to any particular adrenal hormone excretion pattern. Results clearly demonstrate the value of applying knowledge about in situ social behaviour to ex situ management practices. Conversely, however, non-invasive hormone monitoring conducted ex situ may help us to identify physiological phenomena of potential relevance for future in situ studies.

We tested this idea for the sabellariid polychaete Phragmatopoma lapidosa by investigating ontogenetic changes in phototaxis and geotaxis of well-fed, laboratory-reared larvae. Larvae at each of 5 age groups were exposed to (1) 8 different light intensities from a directional light source in a horizontal trough and (2) complete darkness in a vertical chamber. Phototaxis changed with age. Half-day old larvae were not responsive to light, 1 d old larvae were positively phototactic, and all older larvae to 28 d age were negatively phototactic. Larvae from 0.5 to 28 d age were positively geotactic with the exception of 5 d old larvae, which lacked a defined response. Consequently, larvae of the predominantly intertidal P. lapidosa did not conform to Thorson's suggestion of continuous positive phototaxis in intertidal species.

Analysis of five short texts on the Amazon region, written in colonial & postcolonial Peru by a diversity of social actors, reveals a pervasive rhetoric of alterity whose content varies according to the particular objectives the authors had in mind. In all cases, however, the aim is the same, namely the imposition of boundaries of differentiation as justification for state integration, expressed in the commodification & symbolic consumption of the Amazonian Other. If the politics of boundary making consist in "peripheralizing" & "Othering" the Amazon & its people, the magic of boundary making resides in the discursive sleight of hand through which contemporary agents conceal the fact that the Amazon has long ago been incorporated into the nation-state. 32 References.

The Si-0 stretch and O-Si-O bond bending force constants determined for palygorskite are similar to equivalent values calculated previously for other phyllosilicates. The Mg-O bond stretch values, on the other hand, are about half of those determined for the equivalent Al-O and Mg-O bond stretch environments in other phyllosilicates, suggesting that the bonding within the octahedral ribbons in palygorskite and sepiolite is weaker than that in the continuous octahedral sheets in micas. The weaker bonding allows more flexible octahedral environments in palygorskite and sepiolite, giving rise to higher probabilities for cation substitutions and vacancies relative to the micas. Above approximately 700 cm (super -1) in the IR and 750 cm (super -1) in the Raman spectra, the eigenmodes are dominated by atomic displacements within the silicate sheets. Below 700 cm (super -1) the eigenmodes become mixed with motions among the Mg octahedra and the silicate sheets; the eigenmodes assigned to the most prominent peaks in the Raman spectra (near 700 cm (super -1) ) belong to this group. As mode frequencies decrease, the corresponding eigenmodes evolve from more localized Mg-O stretch, O-Mg-O bend and O-Si-O bend motions to longer-range motions such as silicate sheet deformations caused by silicate tetrahedra rotation and silicate sheet shearing around the Mg-octahedral sheets.

The calcium monoaluminate occurs as colorless approximately 10 mu m subhedral grains intergrown with grossite, perovskite, and melilite. Nebular condensation is the most likely origin for the precursor materials of this CAI, but calculations suggest that dust/gas ratios substantially enhanced over solar are required to stabilize CaAl (sub 2) O (sub 4) .

In this study, we evaluate the fidelity of four metrics of community evenness (uniformity in species abundances in an assemblage) using a database of 85 molluscan life and death assemblages: Pielou's J (based on Shannon's H), Hurlbert's PIE (complement of Simpson's lambda ), Peters' E (sub ss) , and the complement of PATT (Proportional Abundance of Top Taxon). Initial results indicate that death assemblages tend to show equal or greater (rarely lower) evenness than samples of the local live community. Subsampling analysis and correlation of evenness values indicate that death assemblage evenness is NOT an artifact of the greater sample size (number of individuals, N) or richness (number of species, S) of death assemblages compared to counterpart life assemblages. Although evenness increases with S, this is a statistical artifact due to the rarity of assemblages with high N and low S or vice versa. In study areas where repeated samples of in situ live fauna can be pooled to simulate time-averaging, evenness of the pooled life assemblages falls within the range of single-sample live values rather than approaching that of the corresponding death assemblage. This suggests that in terms of evenness, death assemblages are typically not passively time-averaged accumulations of static local communities. This result requires additional taphonomic processes that diminish the relative importance of top live taxa. These may include (1) geographic admixing of abundant shells from exotic species, (2) temporal mixing of ecologically volatile local communities, or (3) preferential removal/destruction of specimens from the most abundant (small-bodied, short-lived, opportunistic) species. Regardless of specific scenarios, absolute values of evenness metrics should at this point be used with caution in assessing ancient community structure: death assemblages are not passive accumulations of live species abundance-frequencies, and although the general pattern is for greater evenness in death, no universal correction factor is immediately apparent.

Sampling of surface waters over a range of elevations in the region of interest may provide the best means of calibrating the modern delta (super 18) O (sub w) vs. altitude gradient; these waters are more representative of the water that is recorded by carbonate than rainfall. In the Nepal Himalaya, it has been shown that selective sampling of small streams over an elevation transect yields a curved delta (super 18) O (sub w) vs. altitude gradient (R (super 2) = 0.96), which displays increasing depletion in (super 18) O with increasing altitude (Garzione et al., 2000). A curved gradient suggests that Rayleigh fractionation is an important process in rainout, although other processes such as water-vapor exchange during rainfall or evaporation from raindrops can also modify the curve. The delta (super 18) O value of stream water reflects the range of elevations in a drainage basin over which rainfall occurs. In the Nepal Himalaya, we have estimated the median elevation of the drainage basin to be representative of average rainfall elevation. The curve that results from this correction has been shifted to fit a low elevation site at New Delhi, where the delta (super 18) O value of average annual rainfall is known. The resulting relationship can be used to estimate paleoelevation if other climate variables, such as paleotemperature and changes in the delta (super 18) O value of source moisture, are known. Carbonate precipitation has another host of variables that must be considered in determining the error associated with paleoelevation estimates. The uncertainties that are considered here include: 1) the scatter in the delta (super 18) O (sub w) vs. altitude relationship, 2) an additional error of + or -100 m on the estimation of the average elevation of the drainage basin, 3) analytical error of + or -0.1 per mil, 4) + or -5 degrees C uncertainty on the estimation of the temperature of carbonate precipitation, and 5) the scatter in the empirical relationship governing water-carbonate fractionation. These uncertainties are propagated using Taylor series expansion to yield complete errors of + or -800 m at 0 m elevation and + or -1100 m at 3000 m elevation. The latter 3 sources of uncertainty are inherent to all studies using the delta (super 18) O value of carbonates as a proxy for paleoelevation.

The identity of these appendages is under early developmental control and is regulated by homeotic genes linked to genetically similar clusters, termed Hox genes. Under the control of the gene Distal-less (Dll), ventral abdominal appendages paralogous with thoracic walking limbs are expressed in some to most of the 8 to 11 insect abdominal segments typically in basal and extinct clades. Dll is repressed in most insect clades by the Hox genes Ultrabithorax (Ubx), abdominal-A (abd-A), or functional relatives. Mutations in these Hox genes allow expression of Dll as pleuropodia on abdominal segment 1 (Ubx mutation), and prolegs or other appendages variously located on remaining abdominal segments (abd-A mutation). The repression of Dll development by Ubx and abd-A occurs in holometabolous insects such as Drosophila (fly) and Tribolium (beetle). However, in taxa such as Precis (butterfly) and Manduca (moth), Dll is expressed through the derepression of abd-A, allowing development of prolegs in abdominal segments 3 to 6. Because some extant nonholometabolous hexapodan lineages occasionally express abdominal appendages (springtails, bristletails, grasshoppers) and basal holometabolous insect lineages evidently do not, the occurrence of Srokalarva in the late Middle Pennsylvanian of Mazon Creek, Illinois, is significant. This holometabolan fossil suggests that the basal condition for the clade was larvae that bore clawed abdominal legs. The evolution of holometabolan larval development may have been characterized initially by the expression of Dll and thus the presence of abdominal legs, and succeeded by (1) regulation by Ubx and abd-A and the repression of Dll that resulted in an appendageless abdomen, as well as (2) reversal to a more ancestral condition in other lineages by prolegs occurring on some abdominal segments.

Both their inter- and intrafamilial phylogenetic relationships are unclear. All known corylophid larvae have paired abdominal glandular orifices opening dorsally or dorsolaterally. Of the 35 to 40 described genera, larvae are known for only about a third of them. No fossil larval corylophid has ever been described or photographed even though a substantial number of references, mostly unidentified adults, exist in Baltic and Dominican amber. We describe and illustrate the first fossil larval corylophid and highlight its striking resemblance to other onisciform insect larvae. Larva characteristics are as follows: broadly ovate, strongly flattened, 2.3 mm long, 1.6 mm wide, and unicolorous dark brown dorsally. All surfaces are heavily sclerotized with notal surfaces ornamented with six thoracic and nine abdominal lobes (8-9 not fused). All lobes distinctly separated, lacking gills, A9 tergum simple, and lacking urogomphi. The head prognathous subparalellepipedal, short, wider than long, concealed from above by broadly rounded first pronotal lobe; with relatively long, well-developed antennae, probably bearing three segments (second about 50-60% total length), ending in, at least, 3-4 setae, and the apicalmost the strongest and longest; antennae slightly longer than thorax (ratio 11:9); antennae much longer than head width (ratio 5:3); apical fourth of antennae visible from above under anterior pronotal lobe. All legs are well-developed, moderately separated, articulated at base, with simple tarsungulus (leg 3 with 5 segments), basal portion of thoracic lobes maculated of dark brown and yellow. Head plus thorax is about half the length of larva. Thoracic and abdominal lateral lobes bear about ten strong, and well-separated slightly clavate-ornamented setae of various lengths. The extreme onisciform morphology is common to a wide variety of immature terrestrial and aquatic insects, including: Termitaphididae (Heteroptera), Coccoidea (Homoptera), Psephenidae, Discolomidae, some hispine Chrysomelidae (Coleoptera), and the Platypezidae (Diptera). Although there are significant differences in their bauplane, this phenomenon represents a striking example of convergence.

The Regal Ridge showing occurs in complexly deformed metavolcanic rocks in the Yukon-Tanana Terrane, near their contact with a mid-Cretaceous granitic pluton. The emerald crystals occur where quartz veins cut mica-rich layers in a shallowly dipping mica schist of the Upper Devonian Fire Lake mafic metavolcanic unit. At least eight such veins have been found. Most are surrounded by a much more extensive, overlapping mass of fine, dark tourmaline crystals. The tourmaline crystals are locally associated with minor amounts of scheelite, and small amounts of sulfides have been observed to occur within the quartz veins. A zone of sparse, disseminated sulfides apparently coincides with the tourmaline zone, which is surficially marked by ochreous products of oxidation. Green beryl crystals up to 4 cm in length occur in tourmaline zones and, rarely, in the quartz veins. Some of the smaller crystals, and sections of larger crystals, are of gem quality. The Cr content (average 3208 ppm) shows that it is the predominant chromophore. Fluid-inclusion data indicate that the emerald precipitated from a fluid whose maximum salinity was 3 wt.% NaCl equivalent. The oxygen isotopic composition of the emerald is highly variable (12.3 to 14.8 per mil), but there is little difference in corresponding delta D values (-57.3 and -59.8 per mil), respectively), which suggests the presence of an isotopically homogeneous fluid that underwent isotopic exchange with the host rocks without achieving homogenization. The delta (super 18) O values for coexisting quartz and tourmaline from the quartz veins yield temperatures of formation of approximately 365 and 498 degrees C. Based on fluid-inclusion isochoric data, these temperatures correspond to pressures of 1.0 to 2.5 kbar, and inferred depths of 3 to 7.7 km. The close proximity of the granite suggests that it is the source of the Be, although the Be content is low (12 and 13.2 ppm). The source of the Cr is the schist (520 ppm Cr). An (super 40) Ar/ (super 39) Ar age of 109 Ma for a mica sample from the schist could either reflect a thermal overprint age related to the event that produced the emerald crystals, or cooling following intrusion of the adjacent pluton, or both.

A series of radiometric dates on volcanic materials through this sequence permits relatively fine-scale calibration of the timing and duration of volcanic input to the depositional system, transgressive-regressive cycles of the lake, and intervals of valley cutting and filling. The Olorgesailie Formation, accumulated between 0.992 and 0.493 Ma, consists of relatively pure diatomites, reworked diatomites, primary volcanic and reworked volcaniclastic units, and alluvial deposits (clays, silts, and sands with several well-developed paleosols) that bear a rich archeological and paleontological record. After 0.493 Ma, increased tectonic activity initiated a series of valley cutting and filling cycles that continue into Recent times. A working hypothesis attributes the formation of the paleolake to a barrier on the southwest side of the basin, large-scale lacustrine versus alluvial phases of the Olorgesailie Formation to variations in subsidence rates operating on a time scale of 10 (super 4) -10 (super 5) yr, and transgressive-regressive cycles within these sedimentary packages to wet-dry climate cycles on time scales of 10 (super 3) -10 (super 4) yr. Episodes of volcanism were superimposed on these patterns but did not have significant long-term effects on the depositional system.

In his History of Animals Aristotle wrote that mollusks and other "non-copulative" organisms reproduced exclusively by spontaneous generation and would necessarily arise in abundance wherever conditions were appropriate. Salty desert soils and limey mountain bedrock, if infiltrated by meteoric water, could mimic the conditions in marine sediments and therefore give rise to populations of mollusks, which would then die and petrify in situ, creating fossil beds. The Prodromus on Solids (1669) by Nicolaus Steno (1638-1686) is generally acknowledged to be the foundational text of paleontology with its decisive critique of inorganic theories of fossil growth in situ, favored by many prominent scientists of the day. But the Prodromus alludes only briefly to spontaneous generation. There is evidence, however, that contemporary research and arguments against spontaneous generation helped frame Steno's thinking about the origin of fossils. During the period of Steno's initial studies of fossils he collaborated closely with Francesco Redi, who was then engaged in his famous experiments refuting the spontaneous generation of insects. Steno was also in close contact with the microscopicists Jan Swammerdam and Marcello Malpighi, who were studying the reproductive biology of various invertebrates and plants. Coupled with Steno's own anatomical work on reproductive biology, this likely led Steno to rule out spontaneous generation at the outset of his study, allowing him to focus on distinguishing organic from inorganic growths. Interestingly, it was in the context of the spontaneous generation debates that Malpighi defended Steno's theories on fossils and strata, and it was likely through him and his students that these ideas were passed down to later generations of Italian geologists, culminating with Giovanni Arduino, who 1760 laid the foundations for our present geologic timescale.

Synthetic aperture radar (SAR) systems, operating at wavelengths up to 68 cm, permit broad swaths of the surface to be investigated to depths of 1-5 m. Surface-deployed ground penetrating radar (GPR), operating at a 75-cm wavelength, permits more localized studies at depths up to 12 m. In tandem, these radar systems enable definition of process-specific signatures diagnostic of past geologic processes by penetrating dry materials mantling the surface. The 2003 Mars Express and 2005 Mars Reconnaissance Orbiter missions will carry sounding radars to probe the Martian crust in the 100 m to 5 km depth range. SAR and GPR systems have also been proposed for future orbital and landed missions. As a demonstration of the utility of such observations, Earth-based radar observations of Mars confirm that the surface is variably radar reflective, and suggest that radar penetration in many locations will be approximately 10 times the incident wavelength. In light of the extensive surficial deposits that blanket much of Mars, radar may hold the key to unraveling some of the planet's outstanding mysteries (e.g., evolution of the hydrologic cycle). Radar studies of terrestrial analog environments can define expected radar properties for a variety of landforms, and form a guide to interpreting future SAR/GPR data for Mars. Ongoing studies of landforms in Hawaii, Arizona, the Mojave, and the Sahara are providing important clues regarding expected radar performance and likely results on Mars. Such studies highlight the ability of a Mars SAR to characterize morphology beneath the Martian dust layer, map the distribution of high-latitude ground-ice, and locate any relict coastal or fluvial features (e.g., channels or tributaries). A rover-deployed GPR could define stratigraphy at the decimeter-to-meter scale to depths of 10-15 m, thereby helping to establish geologic setting, evaluate the history of aqueous activity, and locate any accessible water. GPR can also provide context for other rover and orbital data sets, and enable 3-D mapping of local stratigraphy to guide subsurface sampling.

In the Bir Kiseiba region of Egypt, 100 km west of Abu Simbel, SIR-C data revealed a tributary network of channels that originates as a widely dispersed pattern in the depression, with an apparent paleoflow direction to the west. The network then becomes a single channel between the bounding scarp to the west and a relict, elevated surface to the east. Following geometric correction of the image data using ground control points, topographic surveys, pebble counts of surface lag, and numerous trenches to determine near surface stratigraphy, it is apparent that a combination of surface and subsurface layers are responsible for the drainage patterns seen in orbital data. Radar dark areas are a function of the near total absorption of the signal, while bright zones are combinations of surficial carbonate lenses, fluvial pebble lenses (point bars) in the near subsurface, and local caliche and iron-rich horizons in the near surface sediments. Using a ground penetrating radar at 400 and 900 Mhz, the dry sand allowed penetration commonly to 2-3 m to local caliche and iron rich horizons, and in the single channel north of Bir Kiseiba, up to 12 m of sediment was transparent to the 400 Mhz radar, allowing us to map the broad base of the channel in three cross-sections. This use of GPR has allowed us to uniquely specify the strength of returns seen in SIR-C images, and to predict subsurface stratigraphy in areas that have not yet been studied in detail. The combination of these two radar techniques has shown that the now hyperarid climate of this desert is not responsible for the present-day landforms, which are inherited from prior pluvial periods. On Mars, where the evidence for climate change is evident even at visual wavelengths, the use of SAR and GPR will help to constrain some of the critical issues of timing, sources and sinks of water.

The nature and timing of this alteration in the Creede district are debated: early studies linked this metasomatism to resurgence of the Bachelor caldera ( approximately 27.5 Ma), but K-metasomatism of later Creede caldera fill ( approximately 26.7 Ma) suggests it may only slightly predate mineralization. To better characterize this alteration, we have examined the macro- and grain-scale trace element and oxygen isotope features of: 1) four traverses sampling wallrocks away from the Amethyst vein; 2) a short traverse across an unmineralized alteration front at Nelson Creek, and 3) five drill cores of paleochannel fill in the wall of the Creede caldera. In each suite, feldspar phenocrysts were replaced by K-feldspar (Or (sub <97) )+ or -I/S+ or -kaolinite. Samples are enriched in K, Rb, and Cs and depleted Na, Sr, and Ca. Fe (sub 2) O (sub 3) /FeO increases with K/Na. Replacement K-feldspar is rich in Rb ( approximately 1000 ppm) and poor in Sr (15-500 ppm) relative to igneous feldspars. Minor but significant differences exist among the suites. K-metasomatism affected both tuff cobbles and their conglomerate matrix throughout all paleochannel cores. Although late, celsian-rich feldspar replacement is common in the paleochannel rocks, it is rare in the other suites. Celsian may represent spent mineralizing fluids that drained from the ore system into the paleochannel. Samples from the paleochannel, like some samples from Amethyst wallrocks, are rich in Pb and Zn, consistent with interactions with mineralizing fluids. Wallrocks from the northern Amethyst mine workings contain coexisting adularia and albite (the latter is absent from the other suites), possibly the result of higher alteration temperatures. Rocks and replacement feldspar alike from the mine workings and the creek traverse have delta (super 18) O values of 4-6 per mil that anticorrelate with whole-rock K/Na, whereas initial results from paleochannel rocks show alteration feldspar and groundmass with delta (super 18) O of 6-8 per mil. These rocks have undergone multiple metasomatic events; our observations raise the possibility of there having been multiple episodes of K-metasomatism in the Creede district.

The Colchester covers an area of more than 100,000 km (super 2) , the Springfield 73,500 to 81,000 km (super 2) , and the Herrin 73,900 km (super 2) . Each has correlatives in the Midcontinent, such that their regional extent varies from 116,000 km (super 2) to 200,000 km (super 2) . The blue-band parting of the Herrin and correlative coal beds suggests that at least the upper bench of this coal represents an expansive coeval mire across much of its area of occurrence, rather than slightly time-transgressive mires. The Colchester coal is thin, but the Springfield and Herrin coals reach nearly 3 m in thickness. High ash yields, dominance of vitrinite macerals, and abundant lycopsids suggest that these Desmoinesian coals were deposited in mostly topogenous (ground- and surface-water fed) mires. The only modern mire complexes that are as widespread are northern-latitude mires. In these modern, cold-climate wetlands, the expanse of the mires is attributed to paludification of an expansive intracratonic area, resulting in impeded drainage, seasonal to permanent waterlogging of the impermeable substrates, and peat accumulation. Except for differences in latitude, (paludification in the Desmoinesian occurred in warm tropical climates), such a model seems applicable to the Desmoinesian coal deposits, as the most widespread coal beds are associated with the most widespread paleosols. Tropical climate settings and eustatic transgressions during optimal cyclothemic conditions of the Late Pennsylvanian also contributed to the thickness of Desmoinesian paleomires. If a compaction ratio of 10:1 is used to interpret original peat thickness, then vast expanses of these peatlands may have been between 13 and 20 m thick. Other factors that contributed to peat thickness and expanse were (1) extremely broad floodplains along large rivers with enough flooding to hydrologically link peatlands and keep them wet, (2) accumulation in a basin surrounded by low relief, which led to minimal sediment input from the rivers, and (3) low rates of tectonic subsidence.

Within an approximately 1000 m-thick continuous continental section that begins with regionally persistent coal deposits and ends with bedded evaporites, wetland environments shrink from mappable coal seams that offer innumerable sampling opportunities to a few map dots, or wet spots, that provide unique collections. The morphological and mineralogical characteristics of associated paleosol profiles also show a similar ecological and climatic trend. Numerous earliest Permian floras (Wolfcampian) differ little from those found in the underlying latest Carboniferous (Virgilian). Sedimentologic features and paleosols indicate widespread, regionally wet to ever-wet conditions typical of wetland environments. Carboniferous elements diminish upwards in the redbeds of the Wichita Group (lower Leonardian Series), where plants are preserved in abandoned to slack-water channel settings that formed under seasonal climates. Humid or wet paleosol morphologies become progressively restricted and replaced by morphologies consistent with drier, semi-arid conditions through the Lower Permian until wet areas are limited to "riparian corridors." The last vestige of Carboniferous wetland taxa occurs in a very small number of fluvial-channel deposits in the middle Clear Fork Group (upper Leonardian Series) that yield abundant tree ferns and broad-leaf seed plants, along with rare tree lycopsids and sphenophylls, all of which required wet conditions. Vertebrate aestivation assemblages in the middle Clear Fork indicate periods of seasonal drought and underscore the exceptional, geographically and temporally restricted aspect of these plant assemblages. Despite the loss of Carboniferous floral elements in the middle Clear Fork Group, restricted wetland environments remain a small but floristically important component of the Permian landscape in the overlying Pease River Group. Such environments yield the region's youngest Permian floras, which have a distinctly Mesozoic aspect.

FWT wetlands exist along more than 35 km of the Mattaponi River where it passes through incised valleys of the Inner Coastal Plain of Virginia. Analyses of sediment collected during intensive tile-collection studies at two marshes and from pairs of 4 m-long vibracores driven through five marshes suggest that overbank fluvial deposition from the main river channel dominate sedimentation patterns only in the uppermost portion of the system. In most of the FWT marshes, sediment patterns reflect many combinations of controls derived from river-estuary interactions, vegetation conditions, geomorphic settings, and geologic history. Increased silt-and-clay loads along the down-river half of the system may be due to the proximity of the estuarine turbidity maximum through the year. Vegetation density, and thus sediment baffling effects, changes significantly both seasonally and spatially during the growing season. Marsh elevation and flood depth also control sedimentation patterns. Inorganic suspended sediment collects more along the river edge in most marshes studied, but pulses of sediment from a small side-valley tributary basin seem to dominate accretion processes across the interior of one marsh. Stratigraphic analyses indicate that marsh and channel positions migrated little during the past 4000 years. At many marshes this stability may be the result of protective and anchoring cliffs upstream, formed during a Holocene(?) episode of meander migration and incision. Across the FWT system, the marshes accreted vertically at a rate similar to the global average sea level rise during the late Holocene (1-2 mm/yr). Existing sediment data suggest that the average position of the fresh-water-salt-water interface migrated very little during the same period.

Plant fossils in Pennsylvanian sequences without coal occur primarily as compression fossils in clastic sediments. Comparative studies demonstrate that "roof-shale" floras, from clastic rocks immediately above coals, and "coal" floras, from the coal beds, are distinct both in taxonomic composition and in the relative proportions of major plant groups that comprise the numerically dominant fossils. Thus, the clastic floras were not drawn from the same species pool or vegetation as the floras that characterize peat-forming mires. The separate species pools for clastic and peat-forming environments each occur throughout tropical Euramerica. When considered in light of the paleogeographic distribution of the respective host lithologies, floras found in clastic sediments had a wider distribution than the peat forming floras. Thus the two species pools had independent paleogeographic distributions. We examined floras from Upper Pennsylvanian shales in New Mexico and found them to be similar to those from Upper Pennsylvanian clastic deposits to the east, from Texas to Europe. The New Mexico floras, however, come from strata deposited in the Ancestral Rocky Mountain foreland on inland floodplains (Missourian) or in coastal deltas/estuaries (Virgilian) in which coal beds are absent or very rare. In contrast, coals are commonly associated with the clastic floras in regions to the east. Models suggest that the change from peat formation to clastic swamp deposits at any one geographic location reflects climatic change from humid/perhumid to seasonally wet. The biogeographic distribution of coal and clastic floras supports this model, suggesting that western areas were rarely wet enough to support peat formation but were wet enough (at times) to support seasonally wet clastic floodplain vegetation. Thus, clastic floodplain vegetation may have existed contemporaneously with peat-forming vegetation, however, as a general rule, this penecontemporaneity was not local but regional. Clastic floras inhabited areas with reduced precipitation, probably of a seasonal nature; the peats characterized humid to perhumid climatic areas.

Over the last decade, ballast water has been the focus of ongoing research into vectors of nonindigenous species (NIS) introductions. More recently, ballast sediment has also come under scrutiny as a possible source of anthropogenically introduced microorganisms. Transoceanic vessels, including tankers and bulk carriers, take on water to maintain their stability during transit. Most often, ballast water is obtained in shallow ports and sediment is incidentally pumped into holding tanks as well. Entrained in this sediment is a wide array of aquatic organisms, including benthic foraminifers, which may be discharged into distant ports when the vessels are subsequently deballasted. At least five NIS foraminiferal species have been reported worldwide, all in active shipping ports, and all are suspected of having been introduced by transoceanic vessels. In this study, we investigated the presence of foraminifers in ballast sediment samples obtained from three locations in the United States. Most of the vessels arriving in Prince William Sound, Alaska are tankers which originated in western U.S. ports, although a few arrive from overseas. The sediment from twelve of these ballasted vessels was sampled, nine of which contained foraminifers, including Ammonia beccarii, Rosalina globularis, Trochammina charlottensis, T. inflata, Miliammina fusca, Jadammina macrescens, Bulimina denudata, Elphidium, Globobulimina, Lagena, and Haplophragmoides. The NIS Trochammina hadai was also present in six samples, often in great abundance. Most of these species were also present in sediment obtained from a ballasted vessel from San Francisco Bay, and about 40% of the individuals were recovered alive. Vessels which have deballasted are referred to as NOBOB (No-Ballast-On-Board). Although most ballast water and sediment has been removed, residual amounts often remain behind. Sediment from eight of these vessels was sampled from the Great Lakes and numerous living individuals of Ammonia, Elphidium, and Textularia were recovered. Clearly, both ballasted and NOBOB vessels are a potential source of nonindigenous foraminiferal introductions.

In an effort to stabilize the taxonomy of this group primary type specimens of most of these species were compared with Globigerinelloides morphotypes from the upper Campanian-Maastrichtian of ODP Site 690 (Weddell Sea), at least two Maastrichtian sample levels at DSDP, Sites 463 and 465 (tropical Pacific), and the Turonian-Maastrichtian of DSDP Site 511 (Falkland Plateau). Ontogenetic morphometric data, coiling metrics and shape analysis based on high-resolution x-ray images from umbilical and edge views were extremely useful in characterizing population variability for each of these planktonically coiled morphotypes. Our results indicate that Late Cretaceous Globigerinelloides include two distinct lineage groups, one with 10 to 15 chambers and the other with 20 to 25 chambers in adult specimens. Differences in chamber shape, chamber size increase rates, and external shell ornamentation are used to delineate species populations within these two lineage groups. Stable isotope analyses of the biometrically differentiated Globigerinelloides taxa will be obtained to determine their relative depth ecologies. Pre-Campanian Globigerinelloides taxa will be similarly analyzed to reconstruct their Late Cretaceous phylogenetic history.

Bones may be reworked from one horizon to another or recovered from geologically complex or mixed sediments. In addition to these problems, the increasing value attached to fossils encourages commercial exploitation of limited and in many cases protected resources, and such exploitation can cause problems such as incomplete or false stratigraphic and locality information. Many such problems could be addressed though reliable and quantitative post-collection tests of provenance. Earlier studies have suggested that the trace element composition of fossil bones reflects the local depositional environment and therefore could be used to indicate provenance, but limits of resolution were not previously tested. Research on a large and well-documented sample of bones from Pleistocene excavations in Kenya, East Africa, demonstrates how trace element chemistry of fossil bone can be used as a natural tracer or fingerprint to uniquely characterize all bones from a single depositional unit and/or excavation site. Most bones from a single depositional unit of c. 1000 yrs duration can be correctly assigned to their original excavation site, even when excavations are separated by <100 m laterally. Despite this high level of geochemical resolution within a single depositional unit, bones from successive stratigraphic levels also can be distinguished accurately on the basis of trace element chemistry. Such high levels of resolution may not be reproducible in all depositional settings (and certainly not in marine settings), but we see no geological reason why the geochemical variation in our test site should be unusually high.; hence, the observed REE variation are likely representative of levels of variation that would be expected in other terrestrial vertebrate-bearing deposits. This is supported by the fact that all previous studies of bone REE geochemistry have successfully discriminated between depositional horizons. This method (which requires <0.005 g of bone) can be used to assess mixing within populations of fossil bones, to test provenance (and therefore age) assignments, to indicate deliberate alteration of fossil bones, and to identify fossils that have been collected or traded illegally.

Students were probed on a variety of topics about the Earth system, including the Earth's interior, features at the Earth's surface, and geologic time. Content analysis along topical and thematic boundaries indicates that students hold a number of misconceptions about the earth. Additionally, a wide range of mental perspectives related to viewing the Earth from a material, transformative, or process state exist, with significant implications for teaching the earth from a system perspective.

Additionally, some features of the biology of these organisms are traceable to the Lower Cretaceous (ca. 130 Ma). Resins, complex mixtures of carbon-rich molecules insoluble in water, have been produced by numerous ancestral vascular plants, including the Medullosales, since as early as the Middle Carboniferous (ca. 305 Ma). Of all plant exudates, including resins, latexes, and gums, distributed in over 485 genera and 144 plant families, it appears that only resins occur in geologic deposits. Nevertheless, the botanical source of many ancient resins remains obscure. As the chemical nature of resins may vary with plant species, the characterization of modern resins by different physicochemical techniques are used to establish the likely botanical origin of ancient resins. However, ancient resins are seldom associated with taxonomically diagnostic plant organs or tissues. C-13 SSNMR is a state-of-the-art research tool that generates spectra (or signatures) of solids. This technique is the only method that can distinguish the botanical sources of a wide variety of ancient and modern resins. Our analyses use a tiny amount of the solid resin (< 0.5 gram) and are non-destructive. Peaks in different regions of the spectra represent different kinds of chemical bonds, distinguished by their resonances, present in the sample. Data from these resins will be presented from four research areas of evolutionary paleobiology. First, the refinement of our knowledge of fossil and modern plant resins by generating a library of C-13 SSNMR chemical signatures for them. Second, from a chemical library of exudate samples, the identification and reconstruction of resiniferous forests can take into account varied plant species that may have been diachronous sources in the same general locality. Third, given the large number of modern resin samples at hand from closely-related plants, there is a basis for commenting on their classification. Fourth, more ancient resin samples may yield data useful to understand the evolution of plant resin types. These chemical approaches provide an alternative and complementary methodology for reconstructing resin-producing forests, particularly for lineages with extant representatives.

Depending on the location of the ice margin, overflow from these lakes was variably directed to the Mississippi, Hudson and St. Lawrence drainage systems and it is thought that switches in routing were accompanied by a response in ocean circulation that produced abrupt climate events. On several occasions the ice dam formed by the Laurentide Ice Sheet was penetrated and massive outburst floods were routed to Hudson Bay and to the Arctic Ocean. In terms of released water volume the largest of these outburst floods was associated with the Kinojevis stage of Glacial Lake Agassiz. The impounded water volume has been estimated as 163,000 km (super 3) and the timing of the outburst coincides with the early Holocene cooling event at 8,200 BP. Although the total water discharge is reasonably well constrained by glacial geological observations, the magnitude and duration of the flood, which have a potential influence on oceanic response, remain matters for speculation. To examine the range of possibilities we use the Spring-Hutter theory to simulate flood hydrographs for floods that originate in subglacial drainage conduits and we develop new theory to treat the case of outburst floods that occur by downcutting of a supraglacial drainage channel. Representative values for flood magnitude and duration are 5 Sv and 1 yr.

Cope, with multimedia annotations AN - 51774303; 2005-000335 AB - Aside from the prolific quantity of publications (in excess of 1200), Edward D. Cope published several huge monographs while engaged to the Wheeler and Hayden Surveys. Cope's 1877 monograph (375 pages, 61 plates); scanned for this CD-ROM; was the result of his field investigations during the Wheeler Survey in New Mexico of 1874. One hundred twenty five years have passed, and now most of the great monographs are lost or relegated to rare book rooms and private collectors. This CD provides a desktop copy for those interested in researching the exciting history of vertebrate paleontology in New Mexico. We have supplemented the historic tome with a multimedia suite of digital audio and video files that includes interviews and videos of prominent paleontologists following in Cope's footsteps in New Mexico. Williamson discusses the Cope's 1874 contributions to geologic knowledge of the San Juan Basin, the colorful fieldman David Baldwin, and personal collecting experiences in the Eocene and Paleocene in New Mexico. Tedford provides historical context of the 1874 expedition, Cope's monograph, and a sketch of the numerous subsequent AMNH researchers in the Espanola Basin. Chaney narrates video segments about the unique Jacona Microfossil Quarry. This Jacona quarry is in the area Cope prospected in 1874. Additional video footage portrays the spectacular Almagre badlands north of Nacimiento (modern Cuba), New Mexico. A period map illustrates his field route and highlights A transcription of a field letter that Cope wrote to his wife is included to provide candid incite into his thoughts on the challenges of expedition. As an addendum we included Cope's paleontology reports as appeared in Wheeler's 1874 and 1875 Annual Reports as well as Cope's first catalog of New Mexico fossil vertebrates. Cope's Eocene and Paleocene publications of New Mexico are recognized as his greatest contributions to science. His monographs stand as veritable works of art. The 1877 New Mexico monograph is even more remarkable when one recalls that the troves of specimens were gathered in merely one three-month field season. Works such as this monograph by Cope represents a primary and awesome effort in systematic research, as well as being the foundation of vertebrate paleontology in New Mexico.

Although glacial deposits are sparse, a surface diamicton and overridden terrain show evidence of deformation. Field study and microstructural analysis indicate that overriding ice caused several different forms of subglacial deformation. Finer sediment, in which resistance to stress diminishes as pore water pressure increases, contains disturbed bedding, distorted contacts, and shears that offset and deform buried fossil trees. Microstructural analysis of diamicton and sand units show evidence of mobilization with a directional component parallel to ice movement. Depth of deformation varies with sediment type and grain size. Deformation of diamicton at the ice interface may penetrate just a few centimeters. In contrast, basal silt and clay in sand sheets interstratified with outwash sand and gravel are deformed at depths reaching 7.9 to 9.0 m beneath overlying till. Thin sections of units overridden during historic surges show readily recognizable microstructural deformation, such as fabric, partings, foliation, folds and offsets. Less conspicuous forms are rotated grains, boudinage, galaxy structure, strain shadows, and silt wisps. Collectively, these suggest ductile and brittle regimes. Deformation attributed to overriding ice is common on the Bering foreland. Although the structures within deformed substrate are clearly linked to overriding ice, they do not definitively distinguish surging flow from normal advance.

We will present new data from one such sequence, the Golden Valley Fm. of western North Dakota. The Golden Valley Fm. is a 20-30 m thick sequence of fluvial mudstones, carbonaceous shales, and lignites. The lower Bear Den Mbr. is highly kaolinitic (up to approximately 80% of clay minerals) and preserves a typical late Paleocene megaflora. The Camels Butte Mbr. has less kaolinite and a typical early Eocene megaflora and vertebrate fauna. Previously the Paleocene-Eocene boundary has been correlated with the Alamo Bluff lignite at the base of the Camels Butte Mbr. Previous pollen work on the GOlden Valley Fm. detected the first appearance datum (FAD) for Intratriporopollenites instructus in the lower part of the Bear Den Mbr. and the FAD of Platycarya just below the top of the Bear Den Mbr. In IETM sections in the Bighorn and Powder River Basins of Wyoming, the FAD of I. instructus is either within or immediately after the IETM, and the FAD of Platycarya is a few tens of meters higher. Thus, the order of FADs is the same in all three areas. Palynomorph FADs suggest that the IETM may begin at the base of or within the Bear Den Mbr., and thus that the high kaolinite clays in this terrestrial section are coincident with the IETM. Although the deposition of kaolinite in the Bear Den Mbr. likely occurred during the IETM, it is unlikely that the kaolin formed in situ, because the kaolinitic sediments are not extensively modified by pedogenesis, and contain leaf compressions that would have been destroyed by intense soil formation.

Some samples contain both brittle and ductile structures, thus implying polyphase deformation or non-uniform pore water pressure. A decimeters-thick diamict produced during the 1993-95 surge in subglacial contact with debris free ice lacks microstructures and appears to be the product of pervasive deformation of preexisting sediment. Penetration of subglacial strain reaching several meters beneath overriding ice caused ductile and brittle deformation in finer-facies outwash. At some sites, ductile deformation confined to thrust planes follows the base of fine-grained, horizontal, organic-rich sand sheets 4.7 meters beneath till. Our results suggest that closely spaced subglacial sediments may have been subject to heterogeneous deformation meters beneath the ice. The paucity of structures in surge till implies deforming bed conditions favored pervasive sediment deformation.

Rooted at the base of multiple, sub-meter sand sheets are dozens of fossil trees (alder and spruce) ranging in diameter up to 19 cm, and typically with fewer than 25 growth rings. The trees remain in the living position, some extending several meters upward into overlying pebble gravel. Trunks demonstrate forms of deformation that suggest a common directional strain parallel to that of overriding ice flow. A typically encountered style of deformation is the centimeter to decimeter offset of tree trunks along horizontal shears confined to thin, strata-bound, clay-rich zones at the base of sand sheets. Additionally, tree trunks are warped and kinked coincident with shear zones. Primary stratification within the lower portion of some sand sheets display deformed laminar bedding and cross-bedding. Fine to medium sand is chaotically deformed with greatest intensity immediately above shears and with diminished severity upward. Such forms of deformation may be attributed to directional stress capable of penetrating several meters of substrate. In this setting, the most logical source of deforming stress is overriding ice.

In particular, if skeletal durability affects preservation potential, large-scale biases may distort the record of durable vs. fragile organisms. This pilot study -- in conjunction with the Paleobiology Database [PBDB] (http://paleodb.org) -- tests the taphonomic importance of durability for selected Phanerozoic benthic organisms. We focused on three major groups (bivalves, gastropods, and brachiopods) and restricted analyses to two time intervals, which currently are best represented in PBDB (Ordovician-Carboniferous and Jurassic-Paleogene). We used 300 genera with the highest number of occurrences ( approximately 63% of 63752 entries for the three groups; PBDB, 6/2002). Multiple species were scored for each genus in terms of body size, shell thickness, reinforcement structures (folds, ribs, spines), and shell mineralogy, using mature specimens from collections or literature sources. The average scores provide a taphonomic durability index for each genus. Preliminary results indicate that the frequency of occurrences of genera in 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, despite striking increases over time in the proportion of aragonitic fauna, overall body size, and shell thickness. For example, even though Paleozoic aragonitic genera are scarce relative to calcitic ones, their average occurrence frequency is comparable. Although some factors are still poorly controlled and the database is preliminary in nature, these initial results constitute fundamentally good news for paleobiology. Taphonomic durability of shelly benthos apparently is NOT the primary determinant of fossil occurrence. Because a temperate-latitude bias in Meso-Cenozoic records should act against rather than for the observed secular changes in body size, shell thickness, and mineralogy, these trends are likely to reflect genuine biological patterns rather than taphonomic artifacts.

The age of the Snyder Quarry dinosaur die-out site in central New Mexico overlaps the radiometric age of the 100-km-diameter Manicouagan impact crater (214+ or -1 Ma). Large impacts are suggested to be associated with global fires, and the dinosaur deaths in the quarry have been attributed to a widespread paleowildfire. These intriguing associations have sparked sedimentologic, petrographic, chemical, and electron microprobe analyses to investigate the possible connections between the wildfire and dinosaur deaths at the quarry. Preliminary analyses of the main fossil bed indicate the 30-cm-thick gray mudstone sharply contacts an underlying 8-cm-thick calcite pelloidal conglomerate containing 0.2-0.5 mm long apatite laths interpreted as fossil teeth of small vertebrates. The likely fecal pellets and total lack of lithics suggest the conglomerate was formed in a sediment-deprived lake. The overlying fossiliferous mudstone contains mudclasts (rip ups), calcite pellets, small fossil teeth, pyrite spherules (<0.02 mm), partly oxidized pyrite grains (1.0-5.0 mm), blackened (burnt) plant fragments, and black bone fragments. The matrix is micrite and cements are calcite, gypsum, and chalcedony. The matrix and rip-up clasts contain occasional silt-sized angular quartz fragments that show highly undular extinction patterns and have numerous inclusions. Several quartz grains contain potential shock-induced PDFs, but these have not been confirmed. Lithic fragments and rip-up clasts are consistent with fine-grained overbank deposition. Chemical analyses of fossil wood indicate 18.5% organic carbon, consistent with burning; tests for soot content are underway. Identical analyses of fossil bone indicate 0.36% organic carbon, 1.05% hydrogen, 0.05% nitrogen, and 1.0% manganese and are inconclusive, due to high manganese content (which can also blacken bone). However, a connection between the wildfire and dinosaur deaths is consistent with blackened, perpendicularly fractured, non-scavenged, nonarticulated, but associated bones of individual skeletons. Some bone fragments have a light bluish gray mineral coating that appeared on an EDS spectrum as a titanium oxide.

Here, we investigate an exceptionally diverse macroflora from caldera-lake beds exposed at Laguna del Hunco, Patagonia, Argentina, paleolatitude approximately 47.5 degrees S. We found 132 types of plant organs from an estimated 107 species, far exceeding previous reports for the site, as well as three datable tuffs and six paleomagnetic reversals. Results indicate that deposition of the most fossiliferous beds occurred from 52.4-51.6 Ma, near the base of magnetic polarity Chron 23. This places the flora within the early Eocene climatic optimum, known for the warmest sustained temperatures of the Cenozoic. Leaf-margin analysis indicates a mean annual temperature near 16 degrees C, in agreement with estimates of coeval sea surface temperatures from the South Atlantic. Terrestrial and marine temperature estimates from the same time interval and comparable paleolatitudes of the Northern Hemisphere are significantly warmer (>20 degrees C), suggesting that the meridional temperature gradient may have been steeper in the Southern Hemisphere.

Their wavelengths are longer than those of aerodynamic ripples by an order of magnitude or more, so an origin mechanism directly related to the saltation/reptation process, like that responsible for aerodynamic ripples, is unlikely. They lack slipfaces, so they are unlike dunes also. Large ripple-like bedforms are observed in numerous locations on Mars, making them a topic tailor-made for study from a comparative planetology perspective. Recent field studies have been conducted at Rogers Dry Lake, Coyote Dry Lake, the Kelso Dunes, Great Sand Dunes National Monument (GSDNM), and in the Coachella Valley, all locations of previous studies of ripple-like bedforms in the literature. The Rogers and Coyote sites had ripple-like bedforms with particles of pebble size atop a deflating playa base. Their cross-sections were similar to, but subtly different from, ripples of similar dimensions found in sandy environments (Kelso, GSDNM, and Coachella). The following generalizations can be drawn from observations at all sites: 1. The ripple index for all cases was approximately 15, although the data are sparse and concentrated toward small wavelengths. 2. A bimodal distribution of particle sizes seems to be required for large ripple-like bedforms to develop. Bedforms of Kelso, GSDNM, and Coachella (granules atop sand) occurred only where granules were present, although not every area covered with granules had developed larger bedforms than aerodynamic ripples. 3. Additional observations are needed to determine whether the granules merely veneer the crests of the bedforms, which was observed at GSDNM and Coachella, or comprise the main body of the bedform, as observed at Kelso. 4. There is a direct correlation between the wavelengths of the large ripple-like bedforms and the size of the particles comprising them. The last observation is particularly useful in the Mars context. By terrestrial analogy, the particle size (as determined from THEMIS observations) of the larger of the observed martian ripple-like bedforms should be demonstrably greater than that of the smaller ripple-like bedforms.

To provide a flow path across dividing ridges, sediment or water commonly filled some closed drainage basins originally created by impacts, such that overflow of surface water could then downcut the ridge. Contemporary erosion of the ridges appears to have expedited the re-integration process independently of through-flowing water, as evidenced by widespread gullies originating near ridge crests. Headward growth of channels, either through runoff channel downcutting or headward extension of groundwater-fed valleys, may have resulted in capture of some closed drainage basins. Sediment infilling appears to have been the most common means for re-integrating drainage basins, particularly at higher elevations, as most impact crater rims and closed intercrater basin divides were not cut by single outflowing channels. Channels like Ma'adim or Parana Valles that outflowed from formerly closed (possibly lacustrine) basins, in contrast, exhibit a suite of morphologic characteristics that are inconsistent with the more typical Noachian small valley networks. These valleys originate full-born at water gaps cut into older drainage divides, which could be impact basin rims or other ridges. These outflowing channels can have sparse tributary networks, with tributaries poorly graded to the outflowing channel thalweg. The valley courses were controlled by original surface topography rather than any apparent structurally-controlled groundwater flow path. The base-level control on these channels can be a distant basin rather than local plains, which can be deeply cut by these flows. For channels outflowing from lacustrine basins, downcutting of the rim could allow rapid discharges of water, much larger than the volume provided by inflowing channels during the time of the overflow. These outflows could overcome other drainage divides downstream of the source basin, re-integrating formerly closed basins. Some channel source basins exhibit morphologic evidence for sedimentary deposits. At Ma'adim Vallis, a clear spillway and a knickpoint along the channel floor allow a characterization of the outflow that carved the valley.

Previous historical analysis demonstrates a massive decline and extinction of exploited species in tropical marine environments, but it was unclear whether there was any general pattern in the decline. Here I present results from a time-series analysis of the condition of the marine biota (megafauna and architects) from 13 coral reef sites from around the world using a consistent analytical framework. Components of the marine megafauna include large and small carnivores and herbivores, and that for the architects include corals, seagrasses and suspension feeders. The state of marine megafauna and architect populations was assessed at seven different time intervals from pre-human (40,000 ybp) to 2000 AD. The six faunal states range from "pristine" to "globally extinct". The results demonstrate a clear trajectory of decline in all major ecosystem components of tropical coastal communities. The pattern of decline happens everywhere in the same sequence, but not synchronously, with some locations ahead of others, and varies among ecological groups. Overfishing at multiple levels of the food chain has not only resulted in the closure of fisheries, but also in dramatic and so far irreversible phase changes in the benthic communities. Our analyses demonstrate that for all of the study areas, including the Great Barrier Reef, present activities of use are not sustainable and haven't been for some period back in time.

All released MOC Narrow Angle (NA) images, through the Primary mission, have been studied for Mars Charts (MC) 13, 24 and 27, as well as selected NA images from MC 2, 8, and 16. Ripple-like features are ubiquitous on Mars; they are not confined to particular physiographic or geologic settings but tend to accumulate within local topographic lows. MOC images show isolated ripple-like features on terrain surrounding concentrations of rippled deposits; isolated individual transverse features are difficult to reconcile with a ripple origin but are consistent with the possibility of individual dunes. There is little evidence in MOC images of possible slip faces on the ripple-like features; this observation is difficult to reconcile with a dune origin for these features unless they have been inactive for a sufficient length of time to obscure the slip face avalanche deposits. The majority of ripple-like features from the equator to both northern and southern mid-latitudes have average wavelengths of 35 m and range between 10 and 60 m. Poleward of 25 latitude, both hemispheres exhibit ripple wavelengths between 60 to 90 m, with some examples exceeding 100 m. Terrestrial studies of large aeolian ripples reveal a correlation between ripple wavelength and the largest particles on the features. Nighttime THEMIS data will provide relative thermal properties of sufficiently large ripple patches, which we predict should correlate with ripple wavelength. Continued data collection will help to provide a semi-quantitative assessment to determine whether Martian ripple-like features are more likely to be formed by dune or ripple processes.

Both sexes in the two species waved their brightly marked front legs during aggressive interactions, and males used these legs to strike and grasp opponents forcefully. During intense battles, male C. mycopelates also butted or pushed with their heads, whereas male C. exophthalma used their more strikingly wide heads to threaten with stereotyped displays, during which they also held their front legs folded against the sides of their eyes. Courtship behavior by male C. mycopelates involved tactile and perhaps visual displays with the tips of their front legs. Both species also fed by sweeping their front legs over the surface of fruiting fungi and by removing the spores from their legs with their mouthparts. Although male head width in C. exophthalma showed positive allometry, portions of the front legs that were used as signals and as weapons did not, and thus were not in accord with theoretical predictions that weapons and display devices would have steeper allometries.

Aerial photocounts showed that numbers at both lakes fluctuated in parallel, from a total of similar to 3.56 million in 1997, then crashing to 1.60 million in 1998. The decline was coincident with a major El Nino, during which hundreds of thousands starved in the Gulf of California. The population rebounded to 3.27 million by 2000, illustrating the species' potentially high survivorship throughout the year. Catastrophic events are evidently the major factors affecting proximate changes in population size. Factors that set the ultimate limit to the population can be clarified through long-term studies at staging areas.Original Abstract: En otono, >99% de los individuos de Podiceps nigricollis se congregan en el Lago de Mono, California, y el Gran Lago de Sal, Utah, lo que crea una oportunidad excepcional para medir las tendencias poblacionales de esta especie comun pero normalmente extensamente distribuida. Conteos mediante fotografias aereas mostraron que los numeros poblacionales en ambos lagos fluctuaron en paralelo, de un total de similar to 3.56 millones en 1997, disminuyendo luego drasticamente a 1.60 millones en 1998. La disminucion fue coincidente con un evento El Nino importante, durante el cual cientos de miles murieron de inanicion en el Golfo de California. La poblacion aumento a 3.27 millones en el ano 2000, lo que ilustra la potencialmente alta supervivencia de esta especie a lo largo del ano. Evidentemente los eventos catastroficos son los mayores factores que afectan a los cambios proximales del tamano poblacional. Los factores que imponen los limites decisivos sobre las poblaciones pueden ser clarificados a traves de estudios a largo plazo en areas de escala.

LAI was measured using four nondestructive methods, calibrated and tested in experiments performed in calibration plots near the OTCs. The four methods were: PAR transmission through the canopy, normalized difference vegetation index (NDVI), hemispherical photography, and allometric relationships between plant stem diameter and plant leaf area. Calibration experiments showed: (1) Leaf area index could be accurately determined from either PAR transmission through the canopy or hemispherical photography. For LAI determined from PAR transmission through the canopy, ecosystem light extinction coefficient (k) varied with season and was best described as a function of PAR transmission through the canopy. (2) A negative exponential function described the relationship between NDVI and LAI; (3) Allometric relationships overestimated LAI. Throughout the two years of this study, LAI was always higher in elevated C sub(a), rising from, 20% during winter, to 55% during summer. This seasonality was driven by a more rapid development of leaf area during the spring and a relatively greater loss of leaf area during the winter, in elevated C sub(a). For this scrub-oak ecosystem prior to canopy closure, increased leaf area was an indirect mechanism by which ecosystem C uptake and canopy N content were increased in elevated C sub(a). In addition, increased LAI decreased potential reductions in canopy transpiration from decreases in stomatal conductance in elevated C sub(a). These findings have important implications for biogeochemical cycles of C, N and H sub(2)O in woody ecosystems regenerating from disturbance in elevated C sub(a).

However, the effect of UVR on the corals is not clear. To study the coral-zooxanthella symbiosis during simulated post-ENSO scenarios, colonies of P. damicornis were exposed to elevated water temperature and ambient UVR until they bleached. The significant decline of zooxanthellae and photosynthetic pigments resulting in bleaching occurred after 41 days of exposure. Bleached corals were then exposed for 48 days to four experimental conditions to test the effects of water temperature (slightly elevated and ambient) and UVR (ambient and reduced) on six symbiosis attributes. Corals kept under ambient water temperature regained zooxanthellae and the concentration of chlorophylls regardless of the exposure to UVR. Corals under slightly elevated water temperature and reduced UVR remained pale. The condition of corals exposed to slightly elevated water temperature and UVR continued to decline in time. Results indicated that exposure to slightly elevated water temperature, UVR, and their synergy hampered the recovery of experimentally bleached corals.

The US Congress has been a space where these issues have been contested since 1898, when Puerto Rico became part of the United States. I analyze the discursive contests that took place during 1990 in Congress over just who were the Puerto Ricans entitled to vote in a plebiscite to decide Puerto Rico's political status. I examine the ways in which the transnational & highly problematic Puerto Rican identity was constructed & contested in this context between Puerto Ricans in the United States & Puerto Ricans in Puerto Rico. 3 Tables, 26 References.

Individual anhydrite crystals are homogeneous in delta (super 34) S, within the + or -1 per mil (2sigma ) uncertainty of the method, but crystal-to-crystal variations are large (+2.5 to +10.9 per mil). The mean delta (super 34) S for anhydrite (+6.4+ or -2.1 per mil, 1sigma ) is significantly lower than earlier results for bulk anhydrite separates (+9.0 to +9.2 per mil). The difference between the mean delta (super 34) S values in these two populations may reflect a grain-size effect, with heavier sulfur concentrated in smaller anhydrite crystals, few of which were analyzed by ion microprobe. Variations in delta (super 34) S show no correlation with complex textures in anhydrite revealed by cathodoluminescence color. Ion-microprobe analyses of delta (super 34) S were also obtained on six ovoid-shaped inclusions of pyrrhotite, chalcopyrite, and/or intermediate sulfide solid solution hosted by silicate or oxide crystals, interpreted to be magmatic (delta (super 34) S = -0.1 to +2.7 per mil; mean +0.7 per mil), and on four irregularly shaped multiphase sulfide fragments in the matrix, interpreted as xenocrystic, which range widely in delta (super 34) S (-3.7 to +5.5 per mil). We evaluate four different mixing scenarios involving (1) magmatic anhydrite and sedimentary sulfate, (2) magmatic anhydrite and hydrothermal anhydrite, and anhydrite and coexisting sulfide crystals precipitated in different domains of a common magma reservoir that were affected by (3) different degrees of degassing or (4) different degrees of crustal sulfur contamination. The model involving physical contamination of sedimentary sulfate is considered untenable. The other three models are considered to be viable, but none of them can explain all observations. The results of this study and other recent investigations prompt a re-evaluation of the sulfur budget for the 1982 El Chichon eruption. We estimate that 2.2X10 (super 13) g of S was emitted, and that 58 wt.% of the sulfur was present as anhydrite prior to eruption, with the remainder in a vapor phase, with H (sub 2) S/SO (sub 2) nearly equal 9. The bulk magmatic delta (super 34) S value for the 1982 El Chichon trachyandesite is estimated as +4.1 to +5.8 per mil, typical of the relatively heavy sulfur isotopic compositions that characterize subduction-related magmas.

The sought precursory pattern is an accelerated rate of seismic energy release. Several cases of seismicity preceding eruptions are analyzed, and three types of situations are briefly discussed: (a) no precursory patterns can be recognized, (b) precursory patterns are difficult to recognize or appear over time scales too short to allow response, and (c) clear precursory patterns can be recognized. The case of forecasting the November 20, 1998 eruption of Volcan de Colima, which influenced the public response, is briefly discussed.

Juvenile clasts from both lava flows and pyroclastic deposits contain phenocrysts of plagioclase>two pyroxenes>Fe-Ti oxides and rare amphibole set in a groundmass of the same minerals and rhyolitic glass (74-77% SiO (sub 2) ). Prior to the eruption, the andesitic magma was stored at a temperature of approximately 900 degrees C based on titanomagnetite-ilmenite equilibrium. The magma had an oxygen fugacity of 10 (super -11.1) , corresponding to 0.8 log units above the NNO oxygen buffer, and water contents in the rhyolitic melt of approximately 2 wt%, suggesting that the magma was water-undersaturated at depth. The presence of amphibole with clear signs of disequilibrium, quartz xenocrysts, and plagioclase (An (sub 50) ) and microphenocrysts (An (sub >50) ) indicate the injection of a new hotter and more mafic andesite into the magma chamber. This process was the main trigger of the 1998-2000 activity.

Three stages of volcanic activity were observed: pre-lava stage, stage of lava eruption, stage of explosive eruptions. Advanced Very High Resolution Radiometer satellite data provided observations of both summit thermal anomalies and ash emission. Daily monitoring of Volcan de Colima was performed using early morning or late night NOAA 12 and 14 satellite passes gathered in real time at our satellite ground receiving station. Seismic observations were carried out by the Red Sismica del Estado de Colima. Good correlations are observed between seismic activity and parameters monitored by satellite during the three stages. Five seismic swarms were recorded during the reactivation period. Four of the seismic swarms coincided with periods of increase in summit temperature and strong ash emissions. It is important to note that the ash emissions were observed a few days before the beginning of seismic swarms. The thermal saturation at the summit was reached a few hours after the beginning of lava effusion on November 20, 1998, and remained at this level until May 1999 even after the lava flow stopped in early February 1999. The lava front was also clearly identified as a source of thermal anomalies and ash plumes. Study of the summit temperature-ash emission relationship allowed us to classify the strong explosions of 1999-2000. The strongest explosion, on February 10, 1999, produced the largest, ash-rich plumes that were detected over a wide area ( approximately 150 km (super 2) ) and near-saturation temperature anomalies (47.2, 48.4 degrees C). The main limitation of volcano satellite monitoring occurs during overcast conditions. Clouds prevented us from monitoring the seismic swarm of July 1998 and the explosion of July 1999. This study shows that satellite monitoring on a near real-time basis is a powerful tool not only for research in volcanology but also as an aid for scientific committees to define probable eruption scenarios during volcanic crisis and for Civil Protection Authorities for risk mitigation due to ash emission and sudden heating of the crater without seismicity.

On 20 November 1998, growth of a new andesitic lava dome began inside a crater produced by an explosion through the summit dome in July 1994. The 1998 block-lava dome grew rapidly at a rate of 4.4 m (super 3) /s, attaining a volume of 3.8X10 (super 5) m (super 3) in 24 h. About mid-day on 21 November the lava dome began to collapse, generating a series of block-and-ash flows that descended the SSW flank at speeds of 80-90 km/h, at intervals of 3-5 min. These pyroclastic flows were mostly deposited in the three branches of Barranca El Cordoban, reaching a maximum distance of 4.8 km from the summit at an altitude of 2040 m. The largest pyroclastic flows were emplaced on 25-26 November and their deposits had an estimated volume of 7.3X10 (super 5) m (super 3) . An andesitic block-lava flow (59 wt% SiO (sub 2) ) then followed down the three branches of Barranca El Cordoban, reaching a maximum distance of 3.8 km in the central branch. The lava fronts of the western and central branches almost touched at 2300 m elevation. The eastern lava flow reached 2.8 km at 2560 m elevation. The total volume of the three lava flows is estimated as 39X10 (super 6) m (super 3) , assuming an average thickness of 20 m. The advance rate of the lava fronts in the early hours reached 36 m/h on steep slopes (up to 40 degrees ). These diminished to 0.2-1.0 m/h on flatter slopes ( approximately 14 degrees ) in early February, as the activity waned. The viscosity of the block-lava flows, estimated from field observations, was extremely high: 10 (super 9) -10 (super 10) Pa-s, approximately 6 orders of magnitude greater than viscosities estimated for fluid basaltic magmas. The lava flows ceased movement in early February 1999, and the style of eruptive activity entered a more explosive phase, with a series of dome explosions that have continued into February 2001.

Geochemical monitoring of the volcano started in January 1996 with collection of fumarolic gases approximately every 3 months from two sites in the summit crater (Z3, approximately 800 degrees C, and Z2, approximately 400 degrees C). Chemical compositions of volcanic gases from the Z2 fumarole showed a peak in S/Cl in the middle of 1997, 14-15 months before the start of the 1998 lava eruption. High-temperature volcanic vapors from Z3 changed progressively in water isotopic composition and showed a weak trend of increasing HCl/HF and a peak in S/Cl at the same time. Starting from the summer of 1997, the volcanic water became gradually enriched in deuterium, which probably indicated an increasing contribution from deep, less degassed magma. A negative correlation between delta D and Cl content for the Z3 fumarolic gases is explained by shallow degassing of the Colima hot lava plug. This hypothesis is consistent with published data on Cl contents and solubilities in magmas and supported by the observed positive trends of S/Cl and HCl/HF with delta D for the Z3 fumarole. Until September 1998, the SO (sub 2) flux from the volcano was at a low level (<100 tons/day), and often below the detection limit of the instrument ( approximately 30 tons/day). A sharp increase in the SO (sub 2) flux was recorded 1 month before the eruption started. It jumped from 400+ or -50 tons/day to 1600 tons/day 2 days before new lava emerged on 20 November 1998. The SO (sub 2) flux correlated well with seismicity. JF - Journal of Volcanology and Geothermal Research AU - Taran, Yuri A AU - Gavilanes, Juan Carlos AU - Cortes, Abel A2 - Luhr, James F.

A good example of this occurred 18.5 ka ago when the eastern flank of the Nevado de Colima Volcano collapsed producing a debris-avalanche deposit that was previously described as one of the largest in the world. The deposit extended from the volcanic summit as far as the Pacific coast, 120 km away. New stratigraphic, sedimentological, and componentry data suggest that the volcanic collapse of Nevado de Colima resulted in a debris avalanche that traveled 20 km southeast to the Naranjo River. There it crashed against a topographic barrier consisting of Cretaceous limestones (Cerro la Carbonera) and the flow direction was diverted to the south down the Naranjo River channel for another 25 km before the avalanche came to a halt. The obstruction of the drainage produced a temporary dam that stored ca. 1 km (super 3) of water and deposited fluvial and slack-water sediments. Some time after the damming, the accumulated water-sediment load was able to overtop the obstructing material and to release a breakout flow with a calculated initial flow discharge of 3.5 million m (super 3) /s. The resulting flood (cohesive debris flow) followed the channel of the Naranjo River and, due to the high erodibility of the channel and introduction of substrate material, the debris flow progressively increased its volume up to 10 km (super 3) , six times its initial volume. This study highlights the relevance of evaluating the potential remobilization of debris-avalanche deposits to initiate large magnitude cohesive debris flows. Therefore, the hazard and risk analysis of future potential events of this nature must consider the pre-eruption conditions and the topography surrounding a volcano.

New ICP-MS trace-element data are also presented for 37 andesites erupted between 1869 and 1982, described in previous publications. These data are used to evaluate mineralogical and whole-rock compositional changes during two well-defined historical eruption cycles: 1818-1913 and 1913-present. The eruptive cycles of Volcan de Colima are dominated by andesitic lavas with approximately 61 wt% SiO (sub 2) , but terminate with major explosive eruptions, as occurred in 1818 and 1913, involving relatively mafic andesites with approximately 58% SiO (sub 2) . Following eruptions of andesitic block-lava flows with approximately 61% SiO (sub 2) in 1961-1962 and 1975-1976, a trend toward lower SiO (sub 2) contents began in 1976 and peaked in 1981, probably as a small volume of deeper, more mafic magma ascended into the shallower andesitic reservoir beneath the volcano. Since then, however, andesitic lavas have become progressively richer in SiO (sub 2) through the 1991 and 1998-1999 eruptions. Andesites erupted between 1961 and 1999 show many subtle but important differences compared to those erupted between 1869 and 1913. Based on rocks of similar SiO (sub 2) content, the 1961-1999 andesites are richer in modal plagioclase and in the elements Y, Nb, Tb, Ho, Er, Yb, and Ta, and they are poorer in modal hornblende and in the elements Ba and Sr. All of these observations are consistent with the interpretation that the magmas of 1961-1999 had significantly lower water contents compared to those erupted in 1869-1913, which diminished the role of hornblende crystallization and enhanced the role of plagioclase crystallization. The relatively lower magmatic water contents for the 1961-1999 andesites imply that the explosive eruption anticipated to terminate the current eruptive cycle will be less powerful than the 1913 eruption. Of equal importance to this question, however, is the role of magmatic degassing. The relatively higher viscosities of andesitic magmas with approximately 61% SiO (sub 2) likely lead to relatively slow ascent rates and more thorough degassing prior to arrival of the magma at the summit crater and its eruption as block lava. In contrast, the lower viscosities of more mafic andesitic magmas with approximately 58% SiO (sub 2) result in faster ascent and greater retention of volatiles, so that they erupt explosively upon reaching the summit crater.

The new lava rapidly reached the S-SW edge of the summit area, beginning the generation of Merapi-type pyroclastic flows that traveled down La Lumbre, and the El Cordoban Western and Eastern ravines, reaching distances of 3, 4.5, and 3 km, respectively. On December 1, 1998, the lava flow split into three fronts that in early 1999 had reached 2.8, 3.1, and 2.5 km in length, advancing down the El Cordoban ravines. The lava flow fronts disaggregated into blocks forming pyroclastic flows. One of the best examples occurred on December 10, 1998. As the lava flow ceased moving in early 1999, activity became more explosive. Strong blasts were recorded on February 10, May 10, and July 17, 1999. The last event developed a 10-km-high eruptive column from which a pyroclastic flow developed from the base, traveling 3.3 km SW from the summit into the San Antonio-Montegrande ravines. Regardless of the mechanism of pyroclastic-flow generation, each flow immediately segregated into a basal avalanche that moved as a granular flow and an upper ash cloud in which particles were sustained in turbulent suspension. When the basal avalanche lost velocity and eventually stopped, the upper ash cloud continued to move independently as a dilute pyroclastic flow that produced a massive pyroclastic-flow deposit and an upper dune-bedded surge deposit. The dilute pyroclastic flow scorched and toppled maguey plants and trees, and sandblasted vegetation in the direction of the flow. At the end of the dilute pyroclastic-flow path, the suspended particles lifted off in a cloud from which a terminal ash fall was deposited. The basal avalanche emplaced block-and-ash flow deposits (up to 8 m thick) that filled the main ravines and consisted of several flow units. Each flow unit was massive, monolithologic, matrix-supported, and had a clast-supported steep front (ca. 1.5 to 2 m thick) composed of boulders up to 1.7 m in diameter. The juvenile lithic clasts had an average density of 1800 kg/m (super 3) . The dilute pyroclastic flow emplaced overbank deposits, found on valley margins or beyond the tip of block-and-ash flow deposits. They consist from bottom to top of a massive medium to coarse sand-size flow layer (2-4 cm thick), a dune-bedded surge layer (2-10 cm thick), and a massive silt-size layer (0.5 cm thick). The total estimated volume of the pyroclastic-flow deposits produced during the 1998-1999 eruption is 24X10 (super 5) m (super 3) .

This activity reached a climax on 20 November 1998 with the extrusion of lava, whose downslope movement was accompanied by pyroclastic flows. Since the major explosion on 10 February 1999, explosive activity has continued up to the time of paper preparation (August 2001). Summit deformation was detected by electronic distance measurement (EDM) surveys. Slope distance measurements were carried out from three base stations utilizing nine fixed reflectors grouped on the volcano edifice at three different altitudes (3250, 3450, and 3850 m). After the destruction of two summit reflectors in July 1998, the EDM surveys were continued, primarily using five reflectors remaining on the north flank of the volcano. Slope distance measurements taken from November 1997 to July 1998 show a maximum cumulative distance change of 0.5 cm/day to the summit reflectors, which is interpreted to result from inflation of the volcanic edifice in response to magma movement towards the surface. EDM variations recorded in August 1998-February 1999 from reflectors on the north flank of the volcano suggest further inflation before extrusion of lava began on 20 November 1998. Subsequent deflation was observed after lava effusion ceased in February 1999. Inflation was measured five days before the 10 February 1999 explosion. No significant deformation of the upper cone has been detected since then.

New andesitic block lava was first sighted from a helicopter on the morning of 20 November 1998, forming a rapidly growing dome in the summit crater. Numerous antecedents to the appearance of the dome were recognized, starting more than a year in advance, including: (1) pronounced increases in S/Cl and delta D values at summit fumaroles in mid-1997; (2) five earthquake swarms between November-December 1997 and October-November 1998, with hypocenters that ranged down to 8 km beneath the summit and became shallower as the eruption approached; (3) steady inflation of the volcano reflected in shortening of geodetic survey line lengths beginning in November-December 1997 and continuing until the start of the eruption; (4) air-borne correlation spectrometer measurements of SO (sub 2) that increased from the background values of <30 tons/day recorded since 1995 to reach 400 tons/day on 30 October 1998 and 1600 tons/day on 18 November 1998; and (5) small ash emissions detected by satellite-borne sensors beginning on 22 November 1997. The seismic and other trends were the basis of a short-term forecast of an eruption, announced on 13 November 1998, with a forecast window of 16-18 November. Although the lava dome actually appeared on 20 November, this forecast is considered to have been a major success, and the first of its kind at Volcan de Colima. Based in part on this forecast, orderly evacuations of Yerbabuena, Juan Barragan, and other small proximal communities took place on 18 November. The lava dome grew rapidly ( approximately 4.4 m (super 3) /s) on 20 November, and was spilling over the SW rim of the crater by the morning of 21 November to feed block-and-ash flows (pyroclastic flows) ahead of an advancing lobe of andesitic block lava. The pyroclastic flows were initially generated at intervals of 3-5 min, reached speeds of 80-90 km/h, and extended out to 4.5 km from the crater. The block lava flow was already approximately 150 m long by the afternoon of 21 November. It ultimately split into three lobes that flowed down the three branches of Barranca el Cordoban on the SSW flank of Volcan de Colima; the lava advanced atop previously emplaced pyroclastic-flow deposits from the same eruptive event, whose total volume is estimated as 24X10 (super 5) m (super 3) . The three lava lobes ultimately reached 2.8-3.8 km from the crater, had flow fronts approximately 30 m high, and an estimated total volume of 39X10 (super 6) m (super 3) . By early February 1999 the lava flows were no longer being fed from the summit crater, but the flow fronts continued their slow advance driven by gravitational draining of their partially molten interiors. The 1998-1999 andesites continued a compositional trend toward relatively higher SiO (sub 2) and lower MgO that began with the 1991 lava eruption, completing the reversal of an excursion to more mafic compositions (lower SiO (sub 2) and higher MgO) that occurred during 1976-1982. Accordingly, the 1998-1999 andesites show no signs of a transition toward the more mafic magmas that have characterized the major explosive eruptions of Volcan de Colima, such as those of 1818 and 1913. A large explosion on 10 February 1999 blasted a crater through the 1998-1999 lava dome and marked the beginning of a new explosive stage of activity at Volcan de Colima. Incandescent blocks showered the flanks out to 5 km distance, forming impact craters and triggering numerous forest fires. Similar large explosions occurred on 10 May and 17 July 1999, interspersed with numerous smaller explosions of white steam or darker ash-bearing steam. Intermittent minor explosive activity continued through the year 2000, and another large explosion took place on 22 February, 2001.

The swarm activity occurred mainly within the southern part of Colima Volcanic Complex. We located about 600 events of magnitude M (sub w) from -0.5 to 2.7 within a 50 km (super 2) area including the active crater of Volcan de Colima and the region between it and the Pleistocene volcano Nevado de Colima 5.5 km to the north. The majority of hypocenters within this area did not exceed 5 km depth below sea level (BSL) and were mainly distributed within the volcanic edifices of Volcan de Colima and Nevado de Colima. We investigated the spatial distribution and spectral properties of events that occurred during three main seismic swarms: in November-December 1997, June-July 1998 and October-November 1998. We identified a temporal change in the depths of events from November-December 1997 and June-July 1998 (from 4 km BSL to 4 km above sea level (ASL)) to October-November 1998 (from 0 to 4 km ASL). Two groups of events with mean P-wave corner frequencies of 5 Hz (LF) and 10 Hz (HF) were distinguished. HF events dominated during the first swarm whereas the LF events were dominant during the June-July 1998 swarm. During October-November 1998, the numbers of HF and LF events were comparable, but very low-frequency low-stress drop events disappeared two days before the eruption. We consider the LF events to have resulted from fracturing along two systems of local faults, whereas the HF events could have been produced by dike movement along these same faults. We propose a model for construction of a magma passageway by the opening of two systems of local faults triggered by magma intrusion.

Acceleration began nearly a year before the eruption, and inverse-rate analysis of measured distances indicates that the time of the eruption could have been predicted. The accuracy increases from approximately + or -5 weeks for predictions made 25 weeks in advance, down to + or -13 to + or -15 days for predictions made 4 weeks in advance. More regular measurement at weekly intervals might have greatly improved the accuracy of the predictions. This and other studies suggest that under some circumstances, for example where observed movements are large and intervals between observations short, regularly repeated ground deformation measurements might give satisfactory predictions of the timing of volcanic eruptions earlier than other methods.

Res. Inst. 36, 99-134]. Measurements of vertical ground deformation across the summit dome complex of Volcan de Colima from a precise levelling network between 1982 and 1999, together with vertical and horizontal displacements derived from dual-frequency GPS measurements in 1994 and 1997, show continuous subsidence. The deformation pattern derived from the levelling shows that subsidence increases towards the summit. The closest stations to the summit (1.1 km distant) show a mean subsidence rate of 5 mm per year compared to the reference station at 2.3 km distance, which may be subsiding itself. Vertical displacements of individual stations since 1982 show that the subsidence has been fairly continuous. The GPS stations, which are distributed more widely and include some close to the edge of the active dome, confirm summit subsidence. The largest measured value, a decrease of 280 mm, or 93 mm subsidence per year, was obtained at the edge of the dome. Horizontal displacements measured during 1994-1997 also show the largest values at the summit, but these are much smaller than the vertical displacements, with the maximum rate of 23 mm per year recorded close to the dome. It is conclusively shown that these measured movements cannot be due to deflation of a buried Mogi source, as vertical and horizontal displacements for some stations are in contrary directions to those predicted by the model, and there is no consistent pattern to the horizontal movements.

This activity has manifested itself through a variety of eruptive processes, culminating in explosive events rated VEI 4. Much of our knowledge of the earlier volcanic events is from non-scientific writings and as such is only an interpretation of sometimes ambiguous information. The most recent eruptions of the 19th and 20th centuries are, however, well documented, scientifically allowing for more detailed understanding of these events.

We believe that such a surface could have a composition of enstatite, plagioclase, diopside, and sulfide, similar to the mineral assemblages found in aubritic meteorites. To test this hypothesis, we investigated the spectra of aubrites and their constituent minerals as analogs for the surface of Mercury. We found that some sulfides have distinctive absorption features in their spectra shortwards of approximately 0.6 mu m that may be apparent in the spectrum of such an object. Determination of the surface composition of Mercury using orbital x-ray spectroscopy should easily distinguish between a lunar highlands and enstatite basalt composition since these materials have significant differences in concentrations of Al, Mg, S, and Fe. The strongest argument against Mercury having an enstatite basalt composition is its extreme spectral redness. Significant reddening of the surface of an object (such as Mercury) is believed to require reduction of FeO to nanophase iron, thus requiring a few percent FeO in the material prior to alteration.

Annual variations appeared to be primarily due to differences in hydrologic conditions over the three years of the study. Differences among wetlands were not related to time since restoration. When data for all sites were combined, annual differences in biomass and most measurements of nutrients (concentrations and standing stocks) did not, however, differ significantly. These results suggest that differences that are measured at individual wetland sites may be less important at the landscape level. Biomass decreased from the outer temporary to inner submersed zone, and there were few differences among wetlands when the temporary, seasonal, and submersed zones were compared. Nutrient concentrations in the plant biomass increased from the temporary zone to the submersed zone, resulting in few differences in nutrient standing crops across zones. Results from this study demonstrate that some measurements of restoration success (i.e., biomass production) should be used cautiously because they are likely to be highly variable among sites and across years and thus may be of limited use in post-restoration monitoring. Other ecosystem parameters (e.g., nutrient concentrations of biomass) are much more constant spatially and temporally, indicating that nutrient cycling processes in vegetation were established quickly following restoration.

Don. from the Oregon Cascades). Percent loss of hydraulic conductivity (PLC), vulnerability curves to xylem embolism and freezing point temperatures of stems were measured over 2 years. Controlled freeze-thaw experiments were also conducted to determine the effect of thaw rate on PLC. During both years, native PLC was significantly higher in winter than in summer for R. macrophyllum. Seasonal changes in PLC were variable in both R. catawbiense and R. maximum. Only R. maximum plants growing in gaps or clearings showed higher PLC than understory plants. A rapid (2-4 day) natural recovery of high native PLC during the winter was observed in both R. maximum and R. macrophyllum. Compared with the bench-dehydration method, vulnerability curves based on the air-injection method consistently had less negative slopes and greater variation. Fifty percent PLC (PLC sub(50)) obtained from vulnerability curves based on the dehydration method occurred at -1.75, -2.42 and -2.96 MPa for R. catawbiense, R. maximum and R. macrophyllum, respectively. Among the study species, R. macrophyllum, which commonly experiences a summer drought, had the most negative water potential at PLC sub(50). In all species, stem freezing point temperatures were not consistently lower in winter than in summer. A single fast freeze-thaw event significantly increased PLC, and R. catawbiense had the highest PLC in response to freezing treatments. Recovery to control PLC values occurred if a low positive hydraulic pressure was maintained during thawing. Rhododendron macrophyllum plants, which commonly experience few freeze-thaw events, had large stem diameters, whereas plants of R. catawbiense, which had small stem diameters, suffered high embolism in response to a single freeze-thaw event. Both drought-induced and winter-induced embolism caused a significant reduction in hydraulic conductivity in all species during periods when drought or freeze-thaw events occurred in their native habitats. However, rapid recovery of PLC following freezing or drought maintained the species above their relatively low margins of safety for complete xylem dysfunction.

Genomic libraries were enriched for one of four microsatellite repeat sequences (CA sub(n), GA sub(n), ATG sub(n) and TAGA sub(n)). Following characterization of microsatellite loci by sequencing, primers were designed and PCR conditions optimized. Microsatellite PCR-amplification was tested in 37 frogs from 8 populations in Costa Rica and Panama. Primer sequences, PCR conditions, allelelic diversities and observed as well as expected heterozygosities in the screened populations are described.

We quantified total aboveground dry biomass (TAGB) in undisturbed central Amazonian rainforests, based on detailed estimates of all live and dead plant material within 20 1ha plots spanning an extensive (ca. 1000km2 ) study area. TAGB values in our study area were very high, averaging 397.7+30.0Mgha-1 . The most important component of aboveground biomass was large (10cm diameter-at-breast-height (DBH)) trees, which comprised 81.9% of TAGB, followed by downed wood debris (7.0%), small trees, saplings, and seedlings (10cm DBH; 5.3%), lianas (2.1%), litter (1.9%), snags (1.5%), and stemless palms (0.3%). Among large trees, aboveground biomass was greatest in intermediate-sized (20-50cm DBH) stems (46.7% of TAGB), with very large (60cm DBH) trees also containing substantial biomass (13.4% of TAGB). There were no significant correlations between large tree biomass and that of any other live or dead biomass component. An analysis based on the variability of our samples suggested that just 3-4 randomly positioned 1ha plots would be sufficient to provide a reasonable estimate of mean TAGB in a landscape such as ours (with 95% confidence intervals being 10% of the mean). This suggests that efforts to quantify Amazon forest biomass should be extensive rather than intensive; researchers should sample many geographically separate areas with a few plots each, rather than sampling a small number of areas more intensively.

AN - 71960391; 12147500 AB - Batch cultures of a lithotrophic Fe(II)-oxidizing bacterium, strain BrT, isolated from the rhizosphere of a wetland plant, were grown in bioreactors and used to determine the significance of microbial Fe(II) oxidation at circumneutral pH and to identify abiotic variables that affect the partitioning between microbial oxidation and chemical oxidation. Strain BrT grew only in the presence of an Fe(II) source, with an average doubling time of 25 h. In one set of experiments, Fe(II) oxidation rates were measured before and after the cells were poisoned with sodium azide. These experiments indicated that strain BrT accounted for 18 to 53% of the total iron oxidation, and the average cellular growth yield was 0.70 g of CH2O per mol of Fe(II) oxidized. In a second set of experiments, Fe(II) was constantly added to bioreactors inoculated with live cells, killed cells, or no cells. A statistical model fitted to the experimental data demonstrated that metabolic Fe(II) oxidation accounted for up to 62% of the total oxidation. The total Fe(II) oxidation rates in these experiments were strongly limited by the rate of Fe(II) delivery to the system and were also influenced by O2 and total iron concentrations. Additionally, the model suggested that the microbes inhibited rates of abiotic Fe(II) oxidation, perhaps by binding Fe(II) to bacterial exopolymers. The net effect of strain BrT was to accelerate total oxidation rates by up to 18% compared to rates obtained with cell-free treatments. The results suggest that neutrophilic Fe(II)-oxidizing bacteria may compete for limited O2 in the rhizosphere and therefore influence other wetland biogeochemical cycles.

Although these corals are abundant and widespread, examination of large numbers of specimens indicates that most of them belong in a single, variable species, H. halli Milne-Edwards and Haime, including both solitary and colonial forms. This study has resulted in the recognition of four subspecies of H. halli, the solitary H. halli halli, and three colonial subspecies, H. halli confluens (Hall), H. halli bellonense n. subsp., and H. halli joshuense n. subsp. The three colonial subspecies occur in restricted stratigraphic positions, each in a coral bed in which it is associated and intergrades with solitary H. halli halli. Two additional species of Heliophyllum are recognized in the Hamilton, the small, solitary H. cribellum n. sp. and the dendroid branching H. delicatum Oliver and Sorauf. The former has been found only in the Centerfield Limestone, lower Ludlowville Formation; the latter is limited to the lower Deep Run Shale, Moscow Formation. Heliophyllum halli flourished in muddy but well-oxygenated parts of the Hamilton sea floor because basal, rootlike structures (talons) and shape adaptations helped keep the living polyp from being overwhelmed by the mud. Septal carinae are thought to have helped anchor the polyps in their calices, perhaps making it easier for them to remove any sediment that accumulated on the oral surface. Heliophyllum cribellum is common in the Centerfield Limestone, which represents a more calcareous, relatively stable sea floor, while H. delicatum seems to have adapted to a more muddy, subsiding sea floor by fast upward growth. However, both species were associated with solitary H. halli halli, a further indication of the great adaptability of this species.

Hyperdynamism could alter a wide range of population, community, and landscape phenomena, and appears to be evident in fragmented tropical, temperate, and boreal communities. I suggest some potential causes and consequences of hyperdynamism, and argue that the responses of many species and ecological processes to habitat fragmentation can be understood in this context.

Effects of large blooms can be difficult to document because blooms are often unexpected and do not always coincide with scheduled sampling programs. Here we use continuously monitored salinity distributions and optical properties to study the spring bloom of the red tide dinoflagellate, Prorocentrum minimum, in the Rhode River, Maryland, a tributary embayment of upper Chesapeake Bay. Salinity distributions, together with weekly cruise measurements of nutrient concentrations, indicate that the bloom commenced with an influx of nitrate at the mouth due to the arrival of a freshet from the Susquehanna River. Arrival of this freshet at the mouth set up an unstable, inverse salinity gradient within the Rhode River. Continuously monitored absorption and scattering spectra indicated that increases in chlorophyll within the Rhode River initially were due to the influx of chlorophyll that had developed in the main stem of the bay. After the influx, much higher concentrations and steep spatial gradients developed within the Rhode River, subsequent to reduced mixing that accompanied re-establishment of a normal estuarine salinity gradient. We used the monitored absorption and scattering coefficients to determine the effect of the bloom on light attenuation coefficients in the Rhode River. The bloom resulted in a nearly three-fold increase in attenuation coefficient. Attenuation was dominated by chlorophyll in the early stages of the bloom and by detritus after the termination of the bloom. Although the bloom lasted only 20 d, the elevated attenuation coefficients due to the bloom exceeded values that would permit growth of submersed vascular plants for a period of about 45 d.

The analysis included 40 sparid species, 10 closely related species, 10 basal percoids, and two nonperciform outgroup species. The aligned 1140 base pairs of cytochrome b yielded 542 parsimony informative characters. Mutational analysis revealed that third codon position transitions were saturated and, therefore, of questionable use in phylogenetic analysis. However, the third codon position transversions and all first and second codon substitutions were not saturated and thus judged more reliable for inferring evolutionary relationship. Parsimony analysis of the equally weighted nucleotide data, weighted nucleotide data set (saturated position transitions given a weight of zero) supported a monophyletic Sparidae with the inclusion of Spicara, which is traditionally included in Centracanthidae. The previously proposed composition of genera within the six sparid subfamilies (Boopsinae, Denticinae, Diplodinae, Pagellinae, Pagrinae, and Sparinae) were not monophyletic in all analyses. This suggests the feeding types on which the subfamilies are based were independently derived multiple times within sparid fishes. In all analyses, Lethrinidae were sister to Sparidae. Sparoidea (Sparidae, Centracanthidae, Lethrinidae, and Nemipteridae) were monophyletic only in the weighted nucleotide phylogeny.

Although our results were generally consistent with previously published phylogenies based on both morphological and mitochondrial data, our broad taxonomic and geographical sampling design revealed novel insights into the phylogenetic history of Dascyllus that had escaped previous notice. These results include: (a) the polyphyletic nature of D. reticulatus mtDNAs, representing two divergent and geographically separated lineages, one shared with D. flavicaudus and the second forming the sister lineage of D. carneus ; (b) the paraphyly of D. trimaculatus relative to the closely related D. abisella ; and (c) phylogeographical structure within the widespread taxa D. aruanus and D. trimaculatus . Application of a molecular clock permits us to posit a causative role for tectonic and oceanic changes regarding some Dascyllus speciation events. Finally, we mapped body size and the presence or absence of protogynous sex change on the mtDNA tree, and tested published hypotheses regarding determinants of the evolution of mating system and protogyny in the genus. Our data rejected a model based on body size but not one based on phylogenetic inertia. The ability to change sex arose once in the ancestor to the entire genus, and was lost once in the ancestor of the D. trimaculatus complex. For taxa that are as geographically widespread as many Indo-Pacific genera, this study highlights the importance of adequate geographical sampling when inferring patterns of species diversification and life history evolution.

Here, a community of Heliconius butterflies in lowland Panama was studied to investigate patterns of pollen use, and more specifically the ecological changes associated with the recent divergence of Heliconius melpomene Linnaeus) and H. cydno (Doubleday). Considering the seven commonest Heliconius species in the community, 32 types of pollen or spore were encountered in pollen loads but only five pollen species were common. Systematic exploitation of pollen was therefore confined to a small proportion of the flowers visited. Most of the variation in pollen load composition between individuals was explained by differences in collecting locality. The exception was Psiguria, which was used in all habitats by the melpomenehecale clade far more than by the eratosapho clade. This may suggest an ancestral switch within Heliconius towards increased reliance on Psiguria pollen. Heliconius cydno and H. melpomene differed significantly in pollen load composition for three of the five most commonly collected pollen species. This is most probably explained by differences in habitat preference; H. melpomene and its co-mimic H. erato are found in open habitat while H. cydno and its co-mimic H. sapho are found in closed-canopy forest. As melpomene and cydno are known to hybridise occasionally, such differences in adult microhabitat contribute to pre-mating isolation. Habitat divergence between H. cydno and H. melpomene, which is associated with changes in mimicry, must have played a role in their recent speciation.

Correlations between these water contents and major-element compositional data for the pyroxenes, associated spinels, and whole-rock xenoliths demonstrate that these water contents record mantle values that have not been perturbed since the xenoliths were brought to the surface by their host magmas. Broad positive correlations of pyroxene water contents with whole-rock Al (sub 2) O (sub 3) are consistent with water behaving as an incompatible element during peridotite melting. The main control on the range of pyroxene water contents, however, appears to be the redox state of the peridotite, because estimates of oxygen fugacity from Mossbauer (Simcoe) and microprobe data (Mexico) on spinels are negatively correlated with water contents. This is consistent with the dominant mechanism of H incorporation into pyroxene, which is dependent on the oxidation-reduction of iron. Metasomatism of sub-arc mantle-wedge peridotites by oxidized fluids or melts rising from the slab raises the oxygen fugacity of the peridotites, and where temperature is high enough, induces them to partially melt. The oxidation, in turn, lowers the solubility of water in the peridotite minerals, causing more than half of the original water to be expelled. That water enters the hydrous partial melts and these ascend through the lithosphere to feed the arc magmatic system in the upper crust. Low water contents in pyroxenes from sub-arc mantle-wedge peridotites, such as those from Simcoe and some western Mexican sites, therefore appear to be complementary to the high water contents that characterize subduction-zone magmas and fuel their explosive eruptions. An estimate of water budget in subduction zones, however, indicates that the amount of water coming from the dehydration of mantle-wedge anhydrous minerals probably accounts for less than 5% of the total water present in subduction-related magmas. The high water contents of arc magmas thus are mainly attributed to fluids or melts from the slab proper. The relatively dry sub-arc mantle wedge appears to be an effective medium through which subducted water is transported from slabs toward the surface.

Both genera are similar in having a prominent antorbital depression, a parasagittal ridge on the basicranial ramus of the pterygoid that extends from the transverse processes to the basisphenoid, a small temporal fenestra with no external area for adductor muscle attachment, and the same complement of bony protuberances on the skull roof including characteristic posteriorly projecting supratemporal "horns" formed by the squamosal and parietal bones. The morphology identified here is consistent with grouping the Burnetiidae in the Biarmosuchia, rather than in the Dinocephalia or Gorgonopsia as has been previously suggested.

Although they have often been considered to be rare members of deep-sea communities, recent trawling has shown that the relative abundance of some cirrates, especially opisthoteuthids, may be locally or regionally high (e.g., Boyle et al., 1998). Cirrates also are presumed to be primitive, morphologically similar to ancestral octopods (Young et al., 1998), although recent observations indicate unexpected adaptations such as bioluminescence (Johnsen et al., 1999) and possibly diverse feeding modes (Vecchione and Young, 1997). Therefore, knowledge of cirrates may contribute substantially to understanding cephalopod evolution as well as deep-sea biology and ecology. However, because they are fragile, the condition of specimens collected up until the past decade generally has been very poor, and our knowledge of the group is rudimentary. New methods, such as videotapes recorded in-situ and gentle collection by submersibles, have allowed substantial new observations and renewed interest in the group. Participation in the cirrate workshop was by invitation only and was limited to researchers actively working on cirrates. The participants focussed their attention on the following topics: (1) taxonomy and systematics, (2) behavior and functional anatomy, (3) biology, growth, and feeding, and (4) distribution and abundance. One tool that proved to be especially useful throughout these deliberations was a summary of the current status of cirrate nomenclature, prepared for the workshop by Michael Sweeney of the Smithsonian Institution, who unfortunately was unable to travel to Scotland. We present an abridged version of the summary so that it can continue to be of use to researchers who are interested in these fascinating but difficult cephalopods.

Data on known-aged seedlings of three common shade-tolerant canopy tree species (Trichilia tuberculata, Tetragastris panamensis and Quararibea asterolepis) in a Panamanian moist forest are presented. Seedling survival during a severe El Nino dry season (1997-98) was compared with prior long-term survival data, and levels of drought stress were assessed by measuring plant water potentials and gas exchange characteristics. Contrary to prediction, dry-season seedling survival was not dramatically reduced in any species compared with that expected in 'normal' years. In Trichilia and Quararibea, pre-dawn water potentials averaged -2 MPa and midday water potentials about -3 MPa. Stomatal conductances were very low, averaging 26 mmol m super(-2) s super(-1) for Tetragastris and 11-13 mmol m super(-2) s super(-1) for Trichilia and Quararibea. Photosynthetic rates also were very low but consistently positive, averaging 0.8-1.1 mu mol m super(-2) s super(-1). The findings suggest that, once established, seedlings of common tree species in this semi-deciduous forest may be tolerant of drought events.

Because the lakes are so large, it has not been possible to monitor grebe migration with sufficient accuracy to determine when peak numbers are reached. To clarify migration phenology, we analyzed data from 2 isolated wetland areas in southwestern Wyoming where grebes land en route between breeding areas in the interior and Great Salt Lake. Occasional birds, probably non-breeders or failed breeders, begin moving southward as early as mid-June. Migration of postbreeding birds starts in late July, peaks in late August and September, and is largely completed by the end of October; with very small numbers arriving into November. The pattern of migration and number of birds encountered varied annually, but 95% of the migration was usually completed by 15 October. As a result, censuses at the major staging lake made on or after 15 October but before the grebes depart for wintering areas can be used to study trends in size of the North American population.

This represents the first comprehensive species-level analysis using insects and results in a hypothesis of Amazonian area relationships that is the most detailed to date. The Charis area cladogram is interpreted as supporting an historical vicariant split between the Guianas and the remainder of the Amazon and then between the upper and lower Amazon. The latter two clades can be further divided into the six most widely recognized areas of endemism and even smaller endemic centers within these, some of which, especially along the Madeira and lower Amazon Rivers, have never been previously hypothesized for butterflies. The overall pattern of historical interrelationships indicated is Guiana + ((Rondonia + (Para + Belem)) + (Imeri + (Napo + Inambari))). The area relationships for riodinid butterflies show substantial congruence with those presented from the literature for amphibians, reptiles, birds, primates, rodents, and marsupials, suggesting a common vicariant history for these organisms. A summary area cladogram generated by combining area cladograms for all the aforementioned groups of organisms indicated the pattern of historical interrelationships to be (Guiana + (Rondonia + (Para + Belem))) + (Imeri + (Napo + Inambari)). Charis cleonus group species distributions are noticeably larger around the upland periphery of Amazonia and smaller in the central and lower regions. A significant positive correlation between the proportion of range area above 100 m and total range size for each species is used to suggest that past sea-level rises may explain smaller range sizes in low-lying regions and that riverine barriers have been important in shaping the current distribution of C. cleonus group species.

This study takes advantage of an open-top CO sub(2) fertilization experiment in a Florida scrub oak community at Kennedy Space Center, Florida, consisting of eight chambers supplied with ambient CO sub(2) (360 ppm) and eight chambers supplied with elevated CO sub(2) (710 ppm). We examined the effects of elevated CO sub(2) on herbivore densities and levels of leaf consumption, rates of herbivore attack by natural enemies and effects on leaf abscission. Cumulative levels of herbivores and herbivore damage were significantly lower in elevated CO sub(2) than in ambient CO sub(2). This may be because leaf nitrogen levels are lower in elevated CO sub(2). More herbivores die of host plant-induced death in elevated CO sub(2) than in ambient CO sub(2). Attack rates of herbivores by parasitoids are also higher in elevated CO sub(2), possibly because herbivores need to feed for a longer time in order to accrue sufficient nitrogen (N), thus exposing themselves longer to natural enemies. Insect herbivores cause an increase in abscission rates of leaves throughout the year. Because of the lower insect density in elevated CO sub(2), we thought, abscission rates would be lower in these chambers. However, abscission rates were significantly higher in elevated CO sub(2). Thus, the direct effects of elevated CO sub(2) on abscission are greater than the indirect effects on abscission mediated via lower insect densities. A consequence of increased leaf abscission in elevated CO sub(2) is that nutrient deposition rates to the soil surface are accelerated.

However, the extent to which geospatial patterns of isotope ratios in avian tissues are influenced by age-specific, altitudinal, and temporal factors remains largely unexplored. We measured carbon ( super(13)C/ super(12)C) and nitrogen ( super(15)N/ super(14)N) isotope ratios in feathers of black-throated blue warblers (Dendroica caerulescens) breeding along a relatively steep altitudinal gradient in the Appalachian Mountains to evaluate the effects of altitude and year on the isotopic signatures of yearling (first breeding season) and older males (>2 years). Breeding males (n super( )= 302) collected during 7 consecutive years exhibited significant age-specific and altitudinal effects in delta super(13)C values and age-specific and temporal effects in delta super(15)N values. The delta super(13)C values of older males increased with altitude at the rate of approximately 1.3ppt per 1,000 m, suggesting a high degree of year-to-year philopatry to narrow altitudinal zones, if not to breeding territories. In contrast, absence of altitudinal patterns in yearlings most likely reflects natal dispersal. Carbon isotope variation ( delta super(13)C = -26.07 to -20.86ppt) observed along a single altitudinal transect (755 m) nearly brackets the range of delta super(13)C values recorded in feathers across the North American breeding range of the warbler from Georgia to New Brunswick (11 degree of latitude) and from New Brunswick to Michigan (22 degree of longitude). These data indicate that age-specific and altitudinal effects must be considered when using delta super(13)C values to delineate the geographic origin of avian species with large altitudinal and latitudinal ranges.

In the marine realm, much work has focused on intertidal invertebrates and on tropical reef fishes, with mixed results. We addressed this problem for a temperate intertidal fish, Clinocottus analis. Our main goal was to determine which life-history stage was most responsible for temporal changes in population size from 1996 to 2000 at 2 sites in San Diego, California, both seasonally and during the 1997 to 1998 El Nino Southern Oscillation (ENSO) event. We approached the problem using cohort analysis and matrix population modeling. Recruitment pulses were evident in population size structure for up to a year, unobscured by post-recruitment mortality, which was not density-dependent. Recruitment was not correlated to spawning adult biomass of 3 mo earlier, suggesting that egg, larval, or early post-settlement processes during those 3 mo determined the magnitude of recruitment, and ultimately, population size. Stage-structured population projection matrices were constructed to compare population growth rates and sensitivities among seasons and between climate periods (El Nino and non-El Nino). Elasticity (prospective) and decomposition (retrospective) analyses of these matrices indicated that the vital rates to which population growth rate ( lambda ) was theoretically most sensitive were not necessarily those responsible for observed temporal differences in lambda . Although lambda was most sensitive to juvenile growth and adult survivorship, fertility (which in this model included fecundity and egg, larval, and early post-settlement survivorship), in addition to juvenile growth, drove observed seasonal differences in lambda . C. analis population size decreased during the 1997 to 1998 El Nino event due to a decrease in recruitment, a decrease in batch fecundity (hydrated eggs per female) and, at 1 site, changes in juvenile survivorship. Results of the study emphasize the power of early life-history events to structure C. analis populations on both seasonal and longer timescales.

AN - 72093587; 12237094 AB - The spermatozoon of felids (cats) survives cryopreservation inconsistently. Using ejaculates from three species (domestic cat [normospermic versus teratospermic], the normospermic serval and the teratospermic clouded leopard), this study (1) determined the influence of adding and removing two permeating cryoprotectants (glycerol and dimethylsulfoxide) and (2) assessed the impact of one-step versus multi-step cryoprotectant removal on sperm motility and membrane integrity. Spermatozoa were exposed in a single step to various anisotonic solutions or to 1M solutions of glycerol or dimethylsulfoxide. In both cases, sperm then were returned to near isotonic conditions in a single or multi-step with de-ionized water, Ham's F10 medium or saline. Percentage of sperm motility was measured subjectively, and plasma membrane integrity was assessed using a dual fluorescent stain and flow cytometry. Sperm motility was more sensitive to anisotonic conditions than membrane integrity. Rapid dilution into various test solutions and removal of cryoprotectant with de-ionized water reduced (P85% spermatozoa retaining intact membranes. However, return to isotonicity with de-ionized water in a single step or multiple steps always caused severe plasma membrane disruption. In contrast, sperm motility and membrane integrity in all species and populations remained unaffected (P>0.05) when spermatozoa were returned to isotonicity in multiple steps with Ham's F10 medium or 0.9% sodium chloride. Results demonstrate that: (1) felid spermatozoa are resistant to hypertonic stress; (2) sperm motility is more sensitive to changes in osmolality than membrane integrity; and (3) removal of cryoprotectant in multiple steps with an isotonic solution minimizes loss of sperm motility and membrane disruption in both normospermic and teratospermic males.

AN - 71736040; 12032242 AB - Antimicrobial peptides are expressed in the skin of amphibians and are used to prevent infection by microorganisms. Frog species store distinct collections of antimicrobial peptides that show variation in size, charge, conformation, and bactericidal activity, and so the evolution of antimicrobial peptide gene families may reflect the adaptive diversification of these loci. We examined the molecular evolution of antimicrobial peptide transcripts from hylid and ranid frog species. Our results show that after the gene family arose in the common ancestor of the Hylidae and Ranidae, before the divergence of these families in the Mesozoic, it subsequently diversified within these groups with numerous duplication events and divergence of loci. Moreover, we provide evidence that suggests that members of the antimicrobial peptide gene family have been subject to diversifying selection within both propiece and mature domains of hylids and solely within the mature domain of ranids. Finally, our results suggest that coordinated and compensatory amino acid replacements have occurred within the acidic propiece and cationic mature domain of hylid antimicrobial peptide precursors, as has been observed for mammalian defensin genes, but not among those of ranid precursors.

Although a groundwater source was previously suggested, the channel originates at a spillway in the divide of a approximately 3,000,000-square-kilometer closed drainage basin. The interior morphology of this source basin, including likely shoreline features following topographic contours, suggests that Ma'adim Vallis was created through catastrophic overflow of a approximately 1,100,000-square-kilometer highland lake. The size, constant levels, and interior morphology of three regional paleolake basins require a warmer paleoclimate and a long-term, recharged, stable highland water table more than approximately 3.5 billion years ago.

Two principal areas were active. About a dozen latest-Pleistocene to precolumbian vents form the 11-km-wide, E-W-trending Cofre de Perote vent cluster (CPVC) at 2300-2800 m elevation on the flank of the largely Pleistocene Cofre de Perote shield volcano and produced an extensive lava field that covers >100 km (super 2) . More widely dispersed vents form the Naolinco volcanic field (NVF) in the Sierra de Chiconquiaco north of the city of Jalapa (Xalapa). Three generations of flows are delineated by cone and lava-flow morphology, degree of vegetation and cultivation, and radiocarbon dating. The flows lie in the behind-the-arc portion of the northeastern part of the MVB and show major- and trace-element chemical patterns transitional between intraplate and subduction zone environments. Flows of the oldest group originated from La Joya cinder cone (radiocarbon ages approximately 42 000 yr BP) at the eastern end of the CPVC. This cone fed an olivine-basaltic flow field of approximately 20 km (super 2) that extends about 14 km southeast to underlie the heavily populated northern outskirts of Jalapa, the capital city of the state of Veracruz. The Central Cone Group (CCG), of intermediate age, consists of four morphologically youthful cinder cones and associated vents that were the source of a lava field >27 km (super 2) of late-Pleistocene or Holocene age. The youngest group includes the westernmost flow, from Cerro Colorado, and a lava flow approximately 2980 BP from the Rincon de Chapultepec scoria cone of the NVF. The latest eruption, from the compound El Volcancillo scoria cone, occurred about 870 radiocarbon years ago and produced two chemically and rheologically diverse lava flows that are among the youngest precolumbian flows in Mexico and resemble paired aa-pahoehoe flows from Mauna Loa volcano. The El Volcancillo eruption initially produced the high effusion rate, short-duration Toxtlacuaya alkaline aa lava flow from the southeastern crater. This 12-km-long hawaiite (average 50.5% SiO (sub 2) ) flow was followed by extrusion of the calc-alkaline Rio Naolinco lava flow from the northwestern crater. This large-volume ( approximately 1.3 km (super 3) ) tube-fed basaltic pahoehoe flow (average SiO (sub 2) 49%) traveled 50 km. Inferred effusion rates suggest emplacement over a decade-long period. Flows of all three age groups are transected by Highway 140 and the railway that form major transportation arteries between Jalapa and Puebla. This area has not previously been considered to be at volcanic risk, but volcanism here has continued into precolumbian time. Future eruptions of similar magnitude and location to those documented here could pose significant hazards to transportation corridors and to densely populated areas in and to the north of Jalapa.

This quantity represents cosmogenic (super 21) Ne produced on the Fish Canyon Tuff surface prior to the deposition of the overlying Carpenter Ridge Tuff. Ancient (super 21) Ne was isolated through the analysis and identification of (1) background (super 21) Ne produced from alpha -particle interactions or inherited; and (2) cosmogenic (super 21) Ne produced from modern radiation. Multiple samples of Fish Canyon Tuff shielded during both exposure periods, 28 Ma ago and in modern time, yielded the background that was then subtracted from all samples. Likewise, samples of Fish Canyon exposed today, but well below the Fish Canyon-Carpenter Ridge contact and therefore shielded 28 Ma ago, yielded a modern component that was also removed from all sample concentrations. The presence of an ancient cosmogenic isotope in a buried surface has several potential applications, including the quantification of paleoelevation, paleolatitude, and pre-Quaternary erosion rates.

The fern is described as an erect false trunk composed of intertwined branch systems and phyllophores embedded in a mesh of adventitious roots. The base of the trunk attained up to 50 cm in diameter and was composed almost totally of roots. Branching of the stems is isotomous. Each subsequent branch gives rise to a phyllophore and a geotropic adventitious root. Smaller roots arise from the bases of the phyllophores, as well as the larger roots, and all are covered with hairs and are directed horizontally. The two forms of roots are functionally complementary, the larger for support and absorption of water from the soil, the smaller for absorption in the humidity within the trunk. The repetitive branching of the stems concomitant with the increase of phyllophores and the two forms of adventitious roots comprised the oldest tree fern with false trunk known to this time. The phyllophores have no apparent phyllotaxy and many are abortive before reaching the exterior of the trunk. The cauline xylem strand, in transverse section, is a solid centrarch protostele while the phyllophore traces are simple and clepsydroid in outline. Xylem strands in the roots have four, rarely three or five, exarch protoxylem points. The combination of the very primitive anatomy with the arborescent habit is unique and the name Symplocopteris wyattii n. gen. et n. sp. is proposed. This plant is the oldest known zygopterid fern showing the clear anatomical and morphological distinction between stems, leaves and roots.

Along its northern margin the Ladakh Batholith intrudes the Shyok Formation, a series of folded and faulted metasedimentary and metavolcanic rocks that are thought to mark an older suture of Cretaceous age. Restoration of Miocene and younger strike-slip movement of approximately 150 km on the Karakoram Fault suggests that the Shiquanhe suture in China was once continuous with the Shyok suture in Kohistan, but no geochronologic evidence for this connection has been demonstrated in the intervening region in Ladakh. The Khardung calc-alkaline volcanic rocks were deposited unconformably on the Shyok Formation and are thought to be of Late Cretaceous age on the basis of fossils and regional correlations, yet no reliable radiometric ages have been published. New Sensitive High Resolution Ion Microprobe (SHRIMP) U/Pb ages on single zircon grains from Khardung volcanic rocks have confirmed that a approximately 7 km thick section was deposited between 67.4 and 60.5 Ma. The underlying Shyok Formation has been difficult to date due to strong thermal overprinting related to both intrusion by the ca. 102-50 Ma Ladakh granites and movement on the younger Karakoram Fault. Near Digar a series of metasedimentary and metavolcanic rocks in structural and metamorphic continuity with the Shyok Formation has experienced less thermal overprinting and a muscovite from a marble unit yields a (super 40) Ar/ (super 39) Ar maximum age ca. 124 Ma, which indicates that greenschist facies metamorphism took place prior to this time. The geochronological evidence is consistent with an Early Cretaceous age for the Shyok Formation, but it further suggests an Early Cretaceous metamorphic and deformational event related to convergence in an oceanic arc setting between the Dras island arc and the Shiquanhe island arc. This metamorphism was followed in the Late Cretaceous by suturing of the Dras island arc to the continental rocks of the Qiangtang Block in westernmost Tibet along the Bangong suture.

Previously, the latter technique only has been used on foraminiferal data from depth transects of modern surface sediment samples. Unlike most methods, which initially compare all possible pairs of samples, the SHE procedure results in a linear pattern if a sequence of samples are from the same statistical distribution. A change in slope indicates a statistical change in community structure and/or a change in species composition. The research reported herein is the first application of SHE for the purpose of identifying biozones in sediment core samples for the purpose of stratigraphic correlation. Both cluster analysis and the SHE method provided zonation within cores. However, the cluster method often produced clusters that were difficult to identify and also contained a mixture of samples without stratigraphic continuity. In contrast, SHE resulted in easily identifiable biozones and ensured temporal continuity within them. In general, the cluster analysis produced more zones than the SHE analysis. About 87% of the cluster zones and 64% of the SHE zones were correlated across more than one core. The average age range for correlated biozone boundaries among the three cores, based on radiocarbon dates, was 821 years using cluster analysis and 296 years using SHE.

Here we examine tropical vs. temperate diversities from the Neogene to Recent using the within-habitat diversity measure Fisher's alpha of Cenozoic benthic foraminifera from the temperate Central Atlantic Coastal Plain and the tropical Central American Isthmus. During the Neogene, the mean value of alpha at temperate latitudes increased 1.4 times or 40%, whereas in the tropics it increased 2.1 times or 106%. Thus, while both areas exhibit an increase of diversity with time, past differences in the rate of increase have generated a more pronounced gradient today (164%) than existed in the Miocene (80%). These data disagree with the suggestion that the world reached an equilibrium number of species during the Paleozoic and demonstrate the need to consider both temperate and tropical components in global diversity assessments.

The warbler attained its greatest abundance (10-20 territorial males/km2) in floodplain forest characterized by small (<25 cm dbh) trees (ca 620-820 stems /ha) and understory thickets of saplings, vines, and shrubs (ca 35,000-48,000 small woody stems/ha). Territories in mature forest typically were associated with disturbance gaps. Canopy height, basal area, and floristics appear to be relatively unimportant factors in habitat selection, provided that understory requirements are met, which explains the warbler's occurrence in regenerating clearcuts as well as in relic tracts of old growth forest. Giant cane (Arundinaria gigantea), hypothesized to be an essential habitat requisite along the northern periphery of its breeding range, was sparse or absent in the prime breeding locations surveyed in this study. Selective thinning and clearcutting are viable habitat management techniques for the Swainson's Warbler. JF - Wilson Bulletin AU - Graves, G R AD - Dept. of Systematic Biology, MRC-116, P.O.

Dependency on mycotrophy in adult life stages would thus be expected to be inversely related to the prevalence of phototrophic structures. The phenology of underground parts and mycorrhizal infection were monitored in five terrestrial species differing in leaf phenology (and thus in phototrophic strategy): Goodyera pubescens (evergreen), Tipularia discolor (wintergreen), Galearis spectabilis and Liparis lilifolia (summergreen) and Corallorhiza odontorhiza (chlorophyll deficient), growing sympatrically in a North American deciduous forest. Mycorrhizal infection was extensive in T. discolor roots and C. odontorhiza rhizomes. Only the proximal part of roots was infected in G. pubescens, and mycorrhizal colonisation was patchy in roots and tubers of G. spectabilis and localized in the rhizome in L. lilifolia. Mycotrophic roots were long-lived (1.5-3 yrs) determinate structures and mycorrhizal infection reached maximum intensity 2-6 months after development. Mycotrophy appeared to be active all year round in mature organs. The phenology of mycotrophic roots and patterns of mycorrhizal infection were not related to the leafy season. The hypothesis that phototrophic and mycotrophic nutrition alternate through the seasons could not be confirmed.

This region has the world's highest absolute rates of forest destruction and fragmentation. Using a GIS, spatial data coverages were developed for deforestation and for three types of potential predictors: (1) human-demographic factors (rural-population density, urban-population size); (2) factors that affect physical accessibility to forests (linear distances to the nearest paved highway, unpaved road and navigable river), and (3) factors that may affect land-use suitability for human occupation and agriculture (annual rainfall, dry-season severity, soil fertility, soil waterlogging, soil depth). To reduce the effects of spatial autocorrelation among variables, the basin was subdivided into > 1900 quadrats of 50 x 50 km, and a random subset of 120 quadrats was selected that was stratified on deforestation intensity. A robust ordination analysis (non-metric multidimensional scaling) was then used to identify key orthogonal gradients among the ten original predictor variables. The ordination revealed two major environmental gradients in the study area. Axis 1 discriminated among areas with relatively dense human populations and highways, and areas with sparse populations and no highways; whereas axis 2 described a gradient between wet sites having low dry-season severity, many navigable rivers and few roads, and those with opposite values. A multiple regression analysis revealed that both factors were highly significant predictors, collectively explaining nearly 60% of the total variation in deforestation intensity (F sub(2,117) = 85.46, P < 0.0001). Simple correlations of the original variables were highly concordant with the multiple regression model and suggested that highway density and rural-population size were the most important correlates of deforestation. These trends suggest that deforestation in the Brazilian Amazon is being largely determined by three proximate factors: human population density, highways and dry-season severity, all of which increase deforestation. At least at the spatial scale of this analysis, soil fertility and waterlogging had little influence on deforestation activity, and soil depth was only marginally significant. Our findings suggest that current policy initiatives designed to increase immigration and dramatically expand highway and infrastructure networks in the Brazilian Amazon are likely to have important impacts on deforestation activity. Deforestation will be greatest in relatively seasonal, south-easterly areas of the basin, which are most accessible to major population centres and where large-scale cattle ranching and slash-and-burn farming are most easily implemented.

Similarity matrix regression analysis showed that overall species similarity was affected by site (the two disjunct halves of the forest area), spatial autocorrelation at the 100 m scale, edaphic conditions, stand type and stand structure, and the occurrence of open areas, but not by stand age or topography. Using autologistic regression we analysed the influence of clumping, site, edaphic conditions, stand composition, open areas, and stand structure on the individual distribution patterns of the 60 most abundant species. Only five species had distributions that were not significantly related to any of the explanatory variables. A large number of species showed significant, and often differing, relationships to at least one of the environmental parameters. At least 20 species exhibited clumping at the 100 m scale that was independent of the environmental parameters. Principal coordinate analysis and an analysis using the Ellenberg ecological indicator values suggested that no important gradients had been overlooked. Dispersal ability (estimated from dispersal mode) and clumping independent of environmental heterogeneity were related. Poor dispersers exhibited stronger clumping at the 100 m scale than good dispersers. Our results support the joint importance of environmental heterogeneity and dispersal processes in shaping the mesoscale distribution patterns of forest herbs. We conclude that the distribution of plant species, and species coexistence and species composition in plant communities, cannot be explained without simultaneously considering environmental heterogeneity and dispersal.

Although initially designed to assess the influence of fragment area on Amazonian biotas, the project has yielded insights that go far beyond the original scope of the study. Results suggest that edge effects play a key role in fragment dynamics, that the matrix has a major influence on fragment connectivity and functioning, and that many Amazonian species avoid even small (<100-m-wide) clearings. The effects of fragmentation are highly eclectic, altering species richness and abundances, species invasions, forest dynamics, the trophic structure of communities, and a variety of ecological and ecosystem processes. Moreover, forest fragmentation appears to interact synergistically with ecological changes such as hunting, fires, and logging, collectively posing an even greater threat to the rainforest biota.

We investigated the soil seed bank, and followed seedlings from emergence and establishment to the sapling stage in artificially created gaps in secondary forest on the Barro Colorado Nature Monument, Panama. * 2 To simulate microsite variation within gaps, litter addition/removal and soil disturbance treatments were applied to seedling plots in a factorial design. * 3 Seedling emergence was almost three-fold higher in litter-free plots than in control plots. * 4 We found a negative relationship between seed mass and seed abundance in the soil, seed mass was positively correlated with seedling emergence success from the seed bank and with seedling survival through to the end of the first dry season. * 5 In the 18 months following the first dry season we observed an uncoupling of seed mass from seedling performance. Seedling mortality was now a function of maximum relative growth rate, with higher mortality of fast-growing species attributable to herbivory, notably by shoot-borers. * 6 We propose that a seed size-dependent trade-off between dispersal success (selecting for large seed number), and emergence-establishment success (selecting for large seed size) can explain the maintenance of wide variation in seed size among pioneer species. Secondarily, a trade-off between growth rate and susceptibility to herbivores acting at the post-establishment phase may contribute to observed differences in light requirements among pioneer species.

We compared life-history phenotypes among 12 populations of the live-bearing fish Brachyrhaphis episcopi. Five populations co-occurred with predatory fish large enough to prey upon adults, while the other seven populations lacked these predators. At sites with large predatory fish, both sexes reached maturity at a smaller size. Females of small to average length that co-occurred with predators had higher fecundity and greater reproductive allotment than those from populations that lacked predators, but the fecundity and reproductive allotment of females one standard deviation larger than mean body length did not differ among sites. In populations with large predatory fish, offspring mass was significantly reduced. In each population, fecundity, offspring size and reproductive allotment increased with female body size. When controlling for maternal size, offspring mass and number were significantly negatively correlated, indicating a phenotypic trade-off. This trade-off was non-linear, however, because reproductive allotment still increased with brood size after controlling for maternal size. Similar differences in life-history phenotypes among populations with and without large aquatic predators have been reported for Brachyrhaphis rhabdophora in Costa Rica and Poecilia reticulata(a guppy) in Trinidad. This may represent a convergent adaptation in life-history strategies attributable to predator-mediated effects or environmental correlates of predator presence.

The subsequent partitioning of fixed carbon into macromolecular pools (carbohydrates, lipids, and proteins) is also affected by UV exposure, although relative changes in allocation are not well-documented and vary considerably. The wavelength specificity of inhibition of photosynthesis has been described by spectral weighting functions, or biological weighting functions (BWFs) that combine the effect of UV radiation with interactive effects of longer wavelengths. BWFs permit one to compare the effects of different radiation sources or various ozone depletion scenarios. However, no data are available from which BWFs for partitioning can be determined, as experimental techniques have varied widely. These BWFs are essential for predicting the effects of increased UV-B on other trophic levels, and for analyzing the cost and benefit of synthesizing protective compounds. Using a polychromatic approach, we are developing BWFs for the partitioning of super(14)C in Thalassiosira pseudonana ( super(3)H) at photosynthetically saturating irradiance. We are comparing these functions to BWFs calculated from simultaneous measurements of primary productivity. We have found consistent differences in sensitivity to UV exposure among the pools, and are testing these differences for significance using a variety of model and calculation approaches.

Here we report a very strong correlation between egg size divergence and cytochrome c oxidase-1 (CO1) amino acid sequence divergence among sister species of bivalve molluscs separated by the Central American Isthmus (i.e., 'geminate' species). Analyses of the molecular data reveal that CO1 sequences likely did not diverge as a function of time or evolve in response to positive natural selection. Given that an excess of CO1 amino acid polymorphism exists within species (as expected if most mutations are only slightly deleterious), a third hypothesis is that reductions in effective population size could simultaneously increase the fixation rate of nearly neutral mtDNA polymorphisms and in some way also facilitate egg size evolution. The remarkable strength of the relationship between egg size and CO1 amino acid sequence demonstrates that, even in the absence of an obvious functional relationship or clock-like evolution, the amounts of molecular and morphological change can be tightly correlated, and therefore may reflect common processes. Accordingly, the assumption that the evolutionary divergence of molecules and morphology are independent must always be carefully examined.

The last remaining population in the US is found in southern Texas, and ranges from 80-120 individuals. Many of these reside in the Laguna Atascosa National Wildlife Refuge (LANWR). Although the cats are protected under the provisions of the Convention on International Trade in Endangered Species (CITES), poachers still seek the cats for their valuable pelts. Of greater threat is the loss of habitat to agricultural conversion. Since most of their habitat is on private lands, voluntary initiatives will provide protection for this species. Farmers are learning that preserving habitat for the protection of game species can be valuable, as they can make up to $10 an acre on hunting revenues.

Launched from England in 1952, the plane quickly accelerated and climbed to an altitude of 35,000 feet, flying at a speed of 460 mph. The Comet was designed to outpace the Douglas DC-3, which dominated the commercial market, and was quickly followed by the DC-4 and the Lockheed Constellation. These propeller-driven planes induced fatigue on long trips. Vibration-free jet engines had to be modified to reduce fuel consumption, which was much higher than that of piston engines at low elevations. The solution was to fly at higher altitudes, which then required pressurized cabins. Although the Comet had a successful first year, two accidents attributed to mechanical problems grounded the plane. Investigators determined that the metal could not withstand the pressure generated at high speeds at high altitudes.

Oocyte diameters and qualitative staging of gonad sections indicated a sustained peak in reproductive state from April to June followed by a decrease in reproductive state by August and a shorter reproductive peak by November. Ripe females censused during both reproductive seasons showed substantial variation in oocyte size suggesting that sporadic, small scale spawning events commonly occur in this population. Counts of urchins in nested quadrats showed that L. variegatus aggregates at no fewer than 4 different spatial scales (0.0625, 0.25, 1.0, and 2.0 m super(2)) with aggregations at larger scales being most common, especially prior to reproductive seasons. A noticeably higher amount of food in guts at these times suggests that these aggregations may be formed during random encounters during periods of increased feeding activity, which may also build up energy reserves for reproduction. Marked urchins were arranged in artificial aggregations of various sizes to investigate potential reproductive interactions. Most urchins moved 1 to 3 m d super(-1) throughout the year. Most encounters among urchins were of short duration and occurred randomly. Urchins placed in the largest aggregations dispersed most slowly during April and June, the periods with the highest mean oocyte diameters. The incidence of heterosexual pairing among naturally occurring pairs of urchins was random, suggesting that L. variegatus may not be able to distinguish gender. Sex ratio of the population was skewed in favor of males. The data suggest that numerous small scale spawning events take place during an extended reproductive season and that intraspecific encounters occur during this season entirely by chance. This method of spawning may enhance outcrossing.

Two pygocephalomorph species are represented; Mamayocaris serendipitous, new species, by hundreds of specimens that appear to be molted exoskeletons, and Paulocaris schrami, new species, by only a few specimens. Mamayocaris has been reported previously from the Lower Permian of Texas and South Dakota and the Upper Carboniferous of Illinois; Paulocaris was previously known only from South America. Associated plant assemblages are dominated by conifers accompanied by other Early Permian and some Late Carboniferous elements. Accompanying vertebrate remains include aquatic to fully terrestrial forms with close taxonomic ties to genera or families recorded in Upper Carboniferous deposits. The fossils are preserved in local deposits of thin (<2 cm), lenticular to nodular beds of limestone and thin (<15 cm) intervals of dark-gray claystone. These deposits accumulated in abandoned, standing-water segments of suspended-load fluvial channels. The archaic nature of these plant and animal assemblages supports previous interpretations that the Permian Petrolia Formation contains paleoenvironmentally isolated biotic elements characteristic of the Carboniferous and underscores prior depictions of the assemblages as relictual.

Rhacophyton, a fern-like plant of the Late Devonian, appears to have been a colonizer of wet substrates, often forming large, nearly monotypic stands in peat-accumulating swamps. The earliest true ferns have been found in environments with high levels of disturbance, often fire, which suggest opportunistic, colonizing life histories, consistent with small, scrambling body plans. During the Early Carboniferous all major body plans and life histories of ferns appear, including scrambling ground cover, tree habit, and lianas. These ecological roles are distributed across several major lineages, including the Zygopteridales, Filicales, and Marattiales, plus some fern-like groups of uncertain affinity, and disappear and reappear independently within these groups. Until the Stephanian, the later part of the Late Carboniferous, ferns largely were confined to secondary ecological roles: colonists, understory vegetation, small vines. Beginning in the latter part of the Westphalian and expanding dramatically in the Stephanian, marattialean tree ferns became the dominant trees of tropical lowland, wetland forests. This dominance continued locally into the Permian in wetter parts of the landscape. The Paleozoic ferns suffered major extinctions at several times, beginning in the Late Carboniferous. By the Permian, new lineages were appearing, some of which would persist into and become dominant vegetational components during the Mesozoic. Among these lineages virtually all of the life histories and body plans that characterized Paleozoic ferns would reappear independently, plus some new kinds of organization and ecology, emphasizing the great evolutionary flexibility and responsiveness of fern-like construction and reproductive biology.

Our objectives were to: (1) inventory the birds in the area, including information on habitat use and abundance, and (2) devise long-term monitoring protocols for birds. We sampled birds through a combination of visual and auditory surveys and mist-netting at 4 well sites and 3 sites along the Urubamba and Camisea rivers. We recorded 420 species during 135 days of field work. We consider the highest priorities for a future monitoring program to be: (1) establish whether edge effects are occurring at well sites, along roads and along the planned pipeline route and determine the significance and extent of these effects and (2) assess the impact of increased human access to the area on game and other exploited species. The remoteness of the area, its rugged terrain and dense vegetation and the lack of trained personnel limit the choice of survey and monitoring methods. We recommend use of mist-netting and transects for monitoring edge effects and use of transects for monitoring game and other exploited species.

Effective evaluation and management of the impacts of development on tropical forests requires appropriate assessment and monitoring tools. We propose the use of 0.1-ha multi-scale, modified Whittaker plots (MWPs) to assess and monitor vegetation in lowland tropical rainforests. We established MWPs at 4 sites to: (1) describe and compare composition and structure of the sites using MWPs, (2) compare these results to those of 1-ha permanent vegetation plots (BDPs), and (3) evaluate the ability of MWPs to detect changes in populations (statistical power). We recorded more than 400 species at each site. Species composition among the sites was distinctive, while mean abundance and basal area was similar. Comparisons between MWPs and BDPs show that they record similar species composition and abundance and that both perform equally well at detecting rare species. However, MWPs tend to record more species, and power analysis studies show that MWPs were more effective at detecting changes in the mean number of species of trees greater than or equal to 10 cm in diameter at breast height (dbh) and in herbaceous plants. Ten MWPs were sufficient to detect a change of 11% in the mean number of herb species, and they were able to detect a 14% change in the mean number of species of trees greater than or equal to 10 cm dbh. The value of MWPs for assessment and monitoring is discussed, along with recommendations for improving the sampling design to increase power.

Emphasis was on long-term societal and environmental benefits in addition to financial gain for the company. The systematic, cyclical adaptive management process was used to generate feedback for SPDP managers. Adaptive management enables ongoing improvement of management policies and practices based on lessons learned from operational activities. Previous to this study, very little information about the local biodiversity was available. Over a 2-year period, the team conducted biological assessments of six taxonomic groups at five sites located within 600 km super(2). A broad range of management options such as location, timing and technology were developed from the beginning of the project. They were considered in conjunction with emerging lessons from the biodiversity assessments. Critical decisions included location of a gas plant and the cost of helicopter access versus roads to service the full field development. Both of these decisions were evaluated to ensure that they were economically and environmentally feasible. Project design changes, addressed in the planning stage, were accepted once consensus was achieved. Stakeholders were apprised of the amplications of the baseline biodiversity assessments.

Among the invaders that will have the largest impacts are those that directly modify ecosystems and thus have cascading effects for resident biota. Exotics can affect ecosystems by altering system-level flows, availability, or quality of nutrients, food, and physical resources (e.g. living space, water, heat or light). The invader-mediated control of physical resources, typically achieved through the modification of habitats, has received limited attention in invasion biology. This reflects a general trend in ecology, and only recently has the concept of ecosystem engineering been developed to account for the role of species that shape habitats. Plants and animals in terrestrial and aquatic systems can both create and destroy structure. When introduced into ecosystems, these exotic engineers cause physical state changes with effects that ramify throughout the system. Although the consequences of these modifications are varied and complex, insight gained from general ecological principles offers an opportunity to predict what invaders will do upon their integration into systems. Examples from the literature suggest that introduced ecosystem engineers that increase habitat complexity or heterogeneity tend to cause abundances and/or species richness to rise, while those that decrease complexity tend to have the reverse effect. In assessing such patterns, however, it is critical to also consider spatial scales and the life habits of resident organisms. In addition to providing predictive power, recognition of engineering as a major means by which invasive species affect ecosystems provides a unifying theme for invasion biology and offers a chance to consider more fully the general role of species in ecosystems.

This occurs because forest remnants have dry, fire-prone edges, are juxtaposed with frequently burned pastures, and are often degraded by selective logging, which increases forest desiccation and fuel loading. Here we demonstrate that in eastern Amazonia, fires are operating as a large-scale edge effect in the sense that most fires originate outside fragments and penetrate considerable distances into forest interiors. Multitemporal analyses of satellite imagery from two frontier areas reveal that fire frequency over 12-14-y periods was substantially elevated within at least 2400 m of forest margins. Application of these data with a mathematical core-area model suggests that even large forest remnants (up to several hundred thousand ha in area) could be vulnerable to edge-related fires. The synergistic interactions of forest fragmentation, logging and human-ignited fires pose critical threats to Amazonian forests, particularly in more seasonal areas of the basin.

But the ability to conserve biodiversity through NTFP management, particularly in extractive reserves in Amazonia, has remained untested. We found that intensive management of Euterpe oleracea (Palmae) fruit, one of the most important extractive products in the Amazon, has substantial impacts on biodiversity, whereas moderate management does not. We mimicked traditional levels of fruit harvest in a replicated experiment over one fruiting season. High-intensity harvest (75% of fruits removed) reduced avian frugivore species diversity by 22%. Low-intensity harvest (40% of fruits removed), however, had no effect on diversity. On a larger scale, we found that forests with enriched densities of E. oleracea supported more fruit-eating birds but fewer non fruit-eating birds than non-enriched forests. Taken together, these results suggest that intensive NTFP management to meet market demands may trigger substantial ecological impacts, at least at the level of our study. E. oleracea harvest should be limited where conservation of biodiversity is a goal.

Understanding fine root responses to changing environmental conditions is critical for predicting the productivity and carbon sequestration potential of forest ecosystems during the 21st century. The first objective of this study is to demonstrate that a mechanistic model can realistically simulate spatial and temporal fine root demography in temperate forests on the basis of two hypotheses: (1) absorption of mineral N (N) stimulates the production of new roots, and (2) fine root longevity decreases with increasing N availability. Based on this model, my second objective is to predict fine root responses to changing atmospheric CO sub(2) levels and N deposition rates. To meet these objectives, an extensive description of the N cycle and the new fine root module were implemented in the ASPECTS model. In agreement with a wide body of literature information, the new model predicted: (1) a preferential colonisation by fine roots of the uppermost soil layer, and (2) a flush of fine root growth in the spring. The simulations indicate that fine root biomass will increase in response to elevated CO sub(2) under the double effect of (1) an increase in root longevity due to increased N stress, and (2) larger amounts of assimilates available to the growth of plant tissue due to increased photosynthesis. Although the simulated total fine root biomass increased under both increasing N deposition rates and atmospheric CO sub(2) concentrations, the model predicts that the distribution of fine roots among soil layers will be altered. This suggests that experimental studies must consider the full depth of the root system in order to accurately assess effects of environmental changes on fine root dynamics. The model also suggests that fine root longevity is a plastic parameter, which varied from less than 1 year to more than 3 years depending on forcing values of N deposition rates and atmospheric CO sub(2) concentrations. Finally, the model indicates that the increase in net ecosystem exchange (NEE) and soil respiration in temperate forests under elevated CO sub(2) will be proportional to the amount of available N, with little to no response in low N conditions and up to +28% for both NEE and soil respiration under the highest deposition rate (7.0 g N m super(-2) y super(-1) ).

Historically, these two types of species have been grouped together as 'cavity-nesters,a but it has become clear that the two nesting habits are associated with very different suites of life-history characters. This paper tests the hypothesis that cavity-adopters differ from excavators and other nest-building species in their propensity to evolve colonial breeding. Because of their dependence on pre-existing cavities, cavity-adopters presumably have less control than excavators over the location of their nests, and this could limit their ability to nest near conspecifics. A literature survey of the nesting behavior of 842 species in 17 bird families shows that coloniality almost never occurs in species that are obligate cavity-adopters. A phylogeny-based comparative analysis of nesting behavior in the Anseriformes indicates that in this group, colonial breeding has evolved less frequently in lineages of cavity-adopters than would be expected by chance. Together, this evidence supports the hypothesis that colonial breeding systems are unlikely to evolve in lineages of cavity-adopters. Evolucion de la Colonialidad en Aves que Nidifican en CavidadesOriginal Abstract: Las aves que nidifican en cavidades pueden dividirse en dos grupos: las especies excavadoras, que construyen sus propias cavidades, y las no-excavadoras, que nidifican en cavidades pre-existentes. Historicamente, estos dos tipos de especies han sido agrupadas colectivamente como aves que anidan en cavidades, pero estudios recientes demuestran que los dos tipos de nidificacion estan asociados con diferentes caracteres de sus historias de vida. En este estudio se pone a prueba la hipotesis que especies no-excavadoras difieren de las excavadoras y de otras especies que construyen nidos en cuanto a su propension a evolucionar habitos de reproduccion colonial. Debido a que dependen de cavidades pre-existentes, las especies no-excavadoras presumiblemente tienen menos control que las excavadoras sobre la ubicacion de sus nidos, y esto podria limitar su habilidad para nidificar cerca de otros miembros de su especie. Una revision bibliografica sobre el comportamiento de nidificacion de 842 especies pertenecientes a 17 familias demuestra que casi nunca se observa colonialidad en especies que obligatoriamente utilizan cavidades pre-existentes. Un analisis comparativo utilizando una filogenia y datos del comportamiento de nidificacion de miembros del orden Anseriformes indica que la colonialidad ha evolucionado con menor frecuencia de lo esperado al azar en linajes de especies no-excavadoras que utilizan cavidades. En conjunto, estos datos apoyan la hipotesis que los sistemas de nidificacion colonial tienen baja probabilidad de evolucionar en linajes de no-excavadoras que anidan en cavidades.

Several species of xylem- and phloem-feeding woodborers consume the wood of living mangrove trees. By girdling, pruning, and hollowing, woodborers killed over 50% of the Rhizophora mangle canopy in experimental plots arrayed across a tidal-elevation gradient. In contrast, leaf-feeding herbivores removed less than 6% of the canopy. In the plots, stem girdlers killed over three branches per tree. The patterns of herbivory by three functional feeding groups were heterogeneous and did not vary consistently with tidal elevation. Because R. mangle lacks viable axillary buds or the ability to produce epicormic shoots to replace pruned branches, the canopy architecture was significantly modified by this damage. The branches that were pruned by stem girdlers created numerous small holes or gaps in the mangrove canopy. Shoot growth and flowering increased in R. mangle trees with 50% of their branches experimentally girdled. Because branches and twigs attacked by woodborers lost their leaves prematurely as greenfall, the quantity and quality of leaf litter were altered when a leaf-bearing branch was girdled or hollowed. These changes suggest that wood-boring insects also significantly affect internal and external nutrient cycling processes in mangrove ecosystems.

Pre-Fox *o- (< Proto-Algonquian *we-) & *i- (< Proto-Algonquian *e-) are continued as o- & i- in some cases, but more frequently both become a-. Words that retained the high-vowel quality of o- & i- (which was sometimes subsequently lost) fall mostly into four sets: enclitics, highly topical nouns, words containing the third-person prefix, & words that bear a valence for an oblique complement. While this distribution is clearly not random, it does not provide an explanation for the retention as long as the unaffected words are considered only as isolated lexical items. When, however, the patterns of the use of these classes of words in sentences are examined, they are all seen to have a greater tendency than others to occur after other words in closely linked phrases. This suggests that the retention of o- & i- can be explained as resulting from the blocking of the regular shift of these vowels to a- at the beginning of words that were closely linked to the preceding word in a phrase. Words with a greater tendency to appear in this sandhi environment generalized o- & i-, while other words tended to generalize a-. This case illustrates how sound change may operate at the sentence level (as Brugmann [1933] argued) & how it may thus correlate indirectly with patterns & categories of syntactic & discourse organization. 43 References.

Cathodoluminescence (CL) petrography of K-metasomatized ash-flow tuffs quickly yields information about the mineralogical changes and reaction mechanisms that take place during alteration for large sample suites and links these properties to geochemical changes. Tertiary volcanic rocks from Creede (Colorado), Socorro (New Mexico), and the Harcuvar Mountains (Arizona), were altered in different geologic settings, yet have very similar CL textures and chemistry. Original igneous feldspars were replaced by adularia primarily by dissolution and crystallization that occurred preferentially along preexisting fractures, surfaces, compositional zoning features, and cleavages. Fluid flow was primarily along grain boundaries, but was in some cases inhomogeneous at the thin-section scale.

However, collecting bias has been demonstrated for most areas of the world and has led some to propose methods that circumvent the need for collections data. New methods that model collections data in combination with abiotic data and predict potential total species distribution are examined using 25,111 records representing 5,123 species of plants and animals from Guyana; some methods use the reduced number of 320 species. These modeled species distributions are evaluated and potential high-priority biodiversity sites are selected based on the concept of irreplaceability, a measure of uniqueness. The major impediments to using collections data are the lack of data that are available in a useful format and the reluctance of most systematists to become involved in biodiversity and conservation research.

Cryotechnology permits long-term storage of valuable genetic material. Although, the actual application to endangered species management requires technical knowledge about sperm freezing and thawing, a systematic understanding of the quantitative impacts of various germ plasm storage and use scenarios is also mandatory. In this study, various GRB strategies were analyzed using the historical data from three managed populations of endangered species with varied pedigrees (Eld's deer, Przewalski's horse, and Sumatran tiger). The following types of sperm banks were assessed: (1) a 'Wild Bank' consisting of sperm (i.e., genes) from 5 to 10 males unrelated to the managed population and to each other; and (2) a 'Best Male' bank containing sperm from only the most genetically valuable males alive in the ex situ population at the time the bank was established. These different bank types were then used to evaluate the effectiveness of different bank usage frequencies. The efficiency of each scenario was assessed by examining the level of inbreeding and gene diversity in the population. Overall, a sperm usage frequency of five times per year was determined to be the most efficient and 'wild banks' were highly successful at enhancing genetic diversity. The value of a GRB established from the ex situ population depends on how closely related the banked males are to future generations. A GRB will have significantly less benefit when banked males also produce many successful offspring, or when donors are already genetically over-represented in the population at the time of establishing the GRB.

Tidal Freshwater Marsh AN - 18573797; 5407851 AB - Sediment deposition and accretion rates in a Virginia tidal freshwater marsh were measured to provide insight to the processes and time scales that are important for maintaining marsh surface elevation. Short-term sediment deposition rates (biweekly to monthly) measured using sediment collection tiles were spatially and temporally variable. Rates were greatest near a tidal creak and decreased along a transect extending toward the marsh interior. When integrated across the entire marsh, annual sediment deposition (as organic carbon) averaged 517 plus or minus 353 g C m super(-2) y super(-1) and was sufficient to balance the effects of existing relative sea level rise and marsh respiration rates. At the creekbank, the highest deposition rates were measured during summer although rates were relatively constant over time at the interior sites. Similar spatial and temporal patterns were obtained when deposition rates were calculated from super(7)Be inventories (monthly time scale). Sediment inventories of super(7) Be were greater than those supported atmospherically, indicating that the spatial patterns of sedimentation were not due to sediment erosion and redistribution within the marsh. Accretion rates calculated from super(137)Cs (decadal scale) and super(14) C dating (centuries to millennia) were substantially less than annual deposition rates, with a decrease in accretion rate with increasing time scale. Mineralization rates of recently deposited sediments (measured as O sub(2) consumption) indicated that sediment metabolism could potentially remove similar to 30% of recently deposited carbon within one month of deposition. The metabolism of a labile sediment fraction could explain a portion of the observed decrease in accretion rate with increasing time scale, with the remainder due to periodic storm-induced erosion and historical variability in sediment deposition rates.

Zimmer had described a new subspecies, M. h. castanea, from the Moyobamba Valley, but Carriker, on the basis of specimens he collected at the same elevation in an adjoining valley, could not find morphological differences between his specimens and the widespread nominate form of M. hemimelaena. Both authors were correct. Two cryptic sister taxa coexist in the foothills of San Martin. Diagnostic vocal and morphological characters and syntopy confirm their status as distinct species. Myrmeciza hemimelaena castanea Zimmer is revived and raised to species status. Concurrently, analysis of the vocalizations and morphology of the lowland population north of the Rio Maranon in Peru, the loudsong recording of which initiated the project, revealed that this population was closely related to M. castanea of which it is described as a subspecies, M. c. centunculorum, under the biological species concept. The discovery that there are two cryptic species in the Myrmeciza hemimelaena complex exemplifies the continuing need to pursue field knowledge and analysis of avian species limits in the Neotropics required for the development of conservation strategies as well as phylogenetic understanding.

This problem has caused an intense debate over whether the present-natural vegetation in this region would be closed forest or more open vegetation. Native large herbivores have been proposed as the key agents creating such open vegetation. Here I address this question by reviewing the palaeoecological evidence regarding vegetation openness in past oceanic interglacials and the pre-agricultural Holocene, i.e. before the onset of strong human impact. I conclude that closed forest would predominate, but include localized longer-lasting openings. Further, open vegetation would be frequent on floodplains, infertile soils, chalklands, and in continental and submeditteranean areas. Large herbivores and fire emerge as likely potential key factors in creating open vegetation in north-western Europe. Fire would probably also be important in the maintenance of light-demanding or short-statured woody species within closed upland forests.

AN - 14616275; 10621659 AB - The decline of the Atlantic salmon population is the concern of the Atlantic Salmon Federation (ASF), which has monitored the loss of this species in many parts of its range. In the past century, commercial sea fishing, industrial development, and pollution have driven away the salmon from many of their spawning rivers. Although conservation efforts addressed these concerns in the 1970s and 80s, the population declined precipitously in the 1990s, in both Europe and the US. Many explanations have been proferred for this decline, including the disruption of spawning beds, pollution or predation in the ocean, and disruption from the growing aquaculture industry. Global warming, salmon poaching, and predation from seals have also been implicated.

To test these alternatives, we compiled data on changing molluscan life habits and trophic composition over 12 million years derived from 463 newly made collections from the southwestern Caribbean. Shelf ecosystems have altered markedly in trophic structure since the Late Pliocene. Predatory gastropods and suspension-feeding bivalves declined significantly in abundance, but not in diversity, and reef-dwellers became common. By contrast, all other ecological life habits remained remarkably stable. Food-web changes strongly support the hypothesis that declining regional nutrient supply had an increasing impact on regional macroecology, culminating in a faunal turnover.

AN - 71491450; 11878640 AB - Landscape structure in a forest mosaic changes with spatial scale (i.e. spatial extent) and thresholds may occur where structure changes markedly. Forest management alters landscape structure and may affect the intensity and location of thresholds. Our purpose was to examine landscape structure at different scales to determine thresholds where landscape structure changes markedly in managed forest mosaics of the Appalachian Mountains in the eastern United States. We also investigated how logging influences landscape structure and whether these management activities change threshold values. Using threshold and autocorrelation analyses, we found that thresholds in landscape indices exist at 400, 500, and 800 m intervals from the outer edge of management units in our study region. For landscape indices that consider all landcover categories, such as dominance and contagion, landscape structure and thresholds did not change after logging occurred. Measurements for these overall landscape indices were strongly influenced by midsuccessional deciduous forest, the most common landcover category in the landscape. When restricting analyses for mean patch size and percent cover to individual forest types, thresholds for early-successional forests changed after logging. However, logging changed the landscape structure at small spatial scale, but did not alter the structure of the entire forest mosaic. Previous forest management may already have increased the heterogeneity of the landscape beyond the point where additional small cuts alter the overall structure of the forest. Because measurements for landscape indices yield very different results at different spatial scales, it is important first to identify thresholds in order to determine the appropriate scales for landscape ecological studies. We found that threshold and autocorrelation analyses were simple but powerful tools for the detection of appropriate scales in the managed forest mosaic under study.

The rock consists predominantly of olivine, pyroxene and chromite phenocrysts, set in a crystalline groundmass of feldspar, pyroxene, ilmenite, troilite and trace metal. Whole-rock shock veins comprise a minor, but ubiquitous portion of the rock. Undulatory to mosaic extinction in olivine and pyroxene phenocrysts and micro-faults in groundmass and phenocrysts also are attributed to shock. Several geochemical signatures taken together indicate unambiguously that NWA 032 originated from the Moon. The most diagnostic criteria include whole-rock oxygen isotopic composition and ratios of Fe/Mn in the whole rock, olivine, and pyroxene. A lunar origin is documented further by the presence of Fe-metal, troilite, and ilmenite; zoning to extremely Fe-rich compositions in pyroxene; the ferrous oxidation state of all Fe in pyroxene; and the rare earth element (REE) pattern with a well-defined negative europium anomaly. This rock is similar in major element chemistry to basalts from Apollo 12 and 15, but is enriched in light REE and has an unusually high Th/Sm ratio. Some Apollo 14 basalts yield a closer match to NWA 032 in REE patterns, but have higher concentrations of Al (sub 2) O (sub 3) . Ar-Ar step release results are complex, but yield a whole-rock age of approximately 2.8 Ga, suggesting that NWA 032 was extruded at 2.8 Ga or earlier. This rock may be the youngest sample of mare basalt collected to date. Noble gas concentrations combined with previously collected radionuclide data indicate that the meteorite exposure history is distinct from currently recognized lunar meteorites. In short, the geochemical and petrographic features of NWA 032 are not matched by Apollo or Luna samples, nor by previously identified lunar meteorites, indicating that it originates from a previously unsampled mare deposit. Detailed assessment of petrographic features, olivine zoning, and thermodynamic modelling indicate a relatively simple cooling and crystallization history for NWA 032. Chromite-spinel, olivine, and pyroxene crystallized as phenocrysts while the magma cooled no faster than 2 degrees C/h based on the polyhedral morphology of olivine. Comparison of olivine size with crystal growth rates and preserved Fe-Mg diffusion profiles in olivine phenocrysts suggest that olivine was immersed in the melt for no more than 40 days. Plumose textures in groundmass pyroxene, feldspar, and ilmenite, and Fe-rich rims on the phenocrysts formed during rapid crystallization (cooling rates approximately 20 to 60 degrees C/h) after eruption.

This later event was previously considered to be "static", but it is actually a complex interaction of deformation, metamorphism and intrusion spanning at least 50 million years. Low-pressure metamorphism began prior to 1118 Ma and contact metamorphism around plutons continued until at least 1070 Ma. GASP barometry, exchange-based thermometry, and assemblage-based thermobarometry all give pressures of 2-4 kbar and temperatures of 475-650 degrees C for pelitic samples. New compilation and mapping of aluminum silicate occurrences in the uplift helps constrain the metamorphic and deformational history of this low-pressure event. Previously unreported occurrences of andalusite in the western region confirm that late metamorphism occurred at low pressure throughout the uplift. In the eastern and western parts of the uplift, andalusite occurs both with and without sillimanite. In the central uplift, sillimanite pseudomorphs after andalusite are present, but no surviving andalusite has been found. Several explanations exist to explain this pattern, including heterogeneous Paleozoic uplift and thermal anomalies related to granitic intrusion. Timing of the aluminum silicates relative to the deformation is variable, but not in any geographic pattern. Aluminum silicates that are pre-, syn-, and postkinematic to the final phase of deformation have all been identified. In the western uplift, muscovite pseudomorphs after andalusite are wrapped by the dominant foliation. In the central uplift, adjacent to the syn-folding Wolf Mountain intrusion, sillimanite pseudomorphs after andalusite are prekinematic to the final phase of deformation and prismatic sillimanite is synkinematic. In the southeastern uplift, several occurrences of andalusite remote from intrusions are pre- to synkinematic to the final phase of deformation. Some andalusite occurrences adjacent to plutons are pre- to synkinematic to intrusion-related deformation. Much of this low-pressure deformation is overprinted by static metamorphism, perhaps related to fluid mobilized during intrusion of the younger granitic bodies.

We describe the hydrological responses of Florida scrub oak to elevated C sub(a) during an eight-month period two years after C sub(a) manipulation began. Whole-chamber gas exchange measurements revealed a consistent reduction in evapotranspiration in response to elevated C sub(a) , despite an increase in leaf area index (LAI). Elevated C sub(a) also increased surface soil water content, but xylem water deuterium measurements show that the dominant oaks in this system take up most of their water from the water table (which occurs at a depth of 1.5-3 m), suggesting that the water savings in elevated C sub(a) in this system are primarily manifested as reduced water uptake at depth. Extrapolating these results to larger areas requires considering a number of processes that operate on scales beyond these accessible in this field experiment. Nevertheless, these results demonstrate the potential for reduced evapotranspiration and associated changes in hydrology in ecosystems dominated by woody vegetation in response to elevated C sub(a) .

Aristolochia is the most diverse genus of Aristolochiaceae, with similar to 120 species distributed throughout the tropics and subtropics. All the Aristolochia species studied so far are pollinated by saprophagous flies of different families, which are presumably deceived by floral odor. Flowers of many species have trap-and-release mechanisms. The flowers attract and imprison pollinators during the female stage first day of flowering and release them after anther dehiscence. Pollination systems of A. maxima and A. inflata are different from those of other Aristolochia in lacking trap mechanisms. Furthermore, the pollinators oviposit in the flowers, and their larvae grow on the fallen, decaying flowers on the ground. Therefore, the plants have a mutualistic relationship with their pollinators. Self-compatible A. inflata is pollinated by Megaselia sakaiae (Phoridae, Diptera). The pollinator may be specialized to Aristolochia flowers, which is the only substrate for larval development. On the other hand, self-incompatible A. maxima is pollinated by Drosophila spp. (Drosophilidae, Diptera), which utilize Aristolochia flowers as a breeding site only occasionally. This pollination mutualism might have evolved from deceit pollination.

We describe experiments to test whether inoculum potential of arbuscular mycorrhizal (AM) fungal communities varies spatially within a broadleaf temperate forest, and also whether there is variability in the effectiveness of AM fungal communities in enhancing seedling growth. Inoculum potential of arbuscular mycorrhizal fungi in a temperate broad-leaved forest did not vary significantly among sites. Inoculum potential, measured as the extent to which the roots of red maple seedlings that had been germinated on sterile sand and then transplanted into the forest, were colonized by AM fungi, was similar in floodplain and higher elevation sites. It was as similar under ectomycorrhizal oaks as it was under red maples and other AM tree species. It was also similar among sites with deciduous understory shrubs with arbuscular mycorrhizae (spicebush, Lindera benzoin) and those with evergreen vegetation with ericoid mycorrhizae (mountain laurel, Kalmia latifolia). Where spicebush was the dominant understory shrub, inoculum potential was greater under gaps in the canopy than within the understory. Survivorship of transplanted red maple seedlings varied significantly over sites but was not strongly correlated with measures of inoculum potential. In a greenhouse growth experiment, arbuscular mycorrhizal fungal communities obtained from tree roots from the forest had different effects on plant growth. Seedlings inoculated with roots of red maple had twice the leaf area after 10 wk of growth compared to the AM community obtained from roots of southern red oaks. Thus, although there appears to be little heterogeneity in inoculum potential in the forest, there are differences in the effectiveness of different inocula. These effects have the potential to affect tree species diversity in forests by modifying patterns of seedling recruitment.

Demographic data from both breeding and non-breeding periods are needed to manage populations of migratory birds, many of which are declining in abundance and are of conservation concern. Although habitat associations, and to a lesser extent, reproductive biology, are known for many migratory species, few studies have measured survival rates of these birds at different parts of their annual cycle. 2. Cormack-Jolly-Seber models and Akaike's information criterion model selection were used to investigate seasonal variation in survival of a Nearctic - Neotropical migrant songbird, the black-throated blue warbler, Dendroica caerulescens. Seasonal and annual survival were estimated from resightings of colour-ringed individuals on breeding grounds in New Hampshire, USA from 1986 to 2000 and on winter quarters in Jamaica, West Indies from 1986 to 1999. Warblers were studied each year during the May-August breeding period in New Hampshire and during the October-March overwinter period in Jamaica. 3. In New Hampshire, males had higher annual survival (0 times 51 plus or minus 0 times 03) and recapture probabilities (0 times 93 plus or minus 0 times 03) than did females (survival: 0 times 40 plus or minus 0 times 04; recapture: 0 times 87 plus or minus 0 times 06). In Jamaica, annual survival (0 times 43 plus or minus 0 times 03) and recapture (0 times 95 plus or minus 0 times 04) probabilities did not differ between sexes. Annual survival and recapture probabilities of young birds (i.e. yearlings in New Hampshire and hatch-year birds in Jamaica) did not differ from adults, indicating that from the time hatch-year individuals acquire territories on winter quarters in mid-October, they survive as well as adults within the same habitat. 4. Monthly survival probabilities during the summer (May-August) and winter (October-March) stationary periods were high: 1 times 0 for males in New Hampshire, and 0 times 99 plus or minus 0 times 01 for males in Jamaica and for females in both locations. 5. These annual and seasonal survival estimates were used to calculate warbler survival for the migratory periods. Monthly survival probability during migration ranged from 0 times 77 to 0 times 81 plus or minus 0 times 02. Thus, apparent mortality rates were at least 15 times higher during migration compared to that in the stationary periods, and more than 85% of apparent annual mortality of D. caerulescens occurred during migration. 6. Additional data from multiple species, especially measures of habitat-specific demography and dispersal, will improve our understanding of the relative impacts of the breeding, migratory, and winter periods on population dynamics of migratory birds and thus enhance future conservation efforts.

Extinction of the organ-pipe Montastraea occurred after more than 500,000 years of dominance in the shallow-water reef habitat of Barbados. Extinction resulted in a morphological shift of the columnar Montastraea lineage from thick to thin columns in modern reef environments. Pleistocene colonies of the columnar morphotype sympatric with organ-pipe Montastraea showed greater column widths than those in allopatry. We subjected our data to a number of criteria for interpreting the morphological shift as character release following lifting of competitive pressure after extinction. The morphological differences do not appear to be due either to chance or to physical properties of the marine environment. Differential local extinction and recolonization of four members of the species complex did not occur on Barbados, so that the species coexisted and appear to have coevolved between more than 600,000 and 82,000 years ago. The morphological shift is related to coral growth form and growth rate, and thus reflects the acquisition of a primary resource in corals-light. Character release occurred at the same oceanic Caribbean island (Barbados) where environments have fluctuated with similar variance throughout the period of coexistence. Not only has competition among living members of the Montastraea 'annularis' species complex been convincingly demonstrated, but trends in relative abundance among fossil members of the species complex strongly suggest that a competitive hierarchy was operating during their Pleistocene coexistence on Barbados. We also observed an ecological analogue to character release on another Caribbean island, Curacao. The distribution and abundance of living columnar M. annularis s.s. and massive M. faveolata from the leeward reef crest in Curacao is greater now than in the Pleistocene, when organ-pipe Montastraea dominated this shallow-water reef habitat. Extinction of the faster growing, shallow-water organ-pipe Montastraea resulted in higher abundance of the columnar Montastraea lineage in shallow-water habitats, where it shifted its morphology to one adapted to high light levels. The species extinction released surviving lineages from a competitive network that had resulted in lower rank abundance in the Pleistocene community and enhanced abundance of both columnar M. annularis s.s. and M. faveolata in modern communities. Full validation of our interpretation of character release must await experiments that demonstrate whether phenotypic differences between populations have a genetic basis. However, we believe the results of this study point to the important, yet heretofore neglected, role that biological interactions have played in the evolution of closely related reef coral species.

Two of the most controversial issues in stream bioassessment, subsampling and taxonomic resolution, have yet to be quantitatively addressed for wetlands. Using a multivariate approach, we evaluated the efficacy of family-, genus-, and species-level assemblage data in reflecting the environment and distinguishing impaired sites from the reference condition. We used 5 basic levels of subsampling (100-, 200-, and 300-organism fixed counts; 10% and 25% fixed areas), an integrated subsample requiring a minimum fixed count and fixed area (100&10%), and 100-count and 10%-area subsamples coupled with a supplementary large-rare (LR) search. Data were obtained from 1.5-m super(2) composite samples collected from 126 plots along a 10-km-long eutrophication gradient in the Florida Everglades. Our results suggest that effectiveness of subsampling depended more upon the minimum number of individuals retained than minimum area or proportion of the sample picked. Fixed-area subsamples were generally less efficient than fixed counts, with 200- and 300-individual fixed counts resulting in significantly greater assemblage-environment relationships and much higher accuracy in detecting impairment than 10% fixed area, despite averaging similar numbers of individuals. The greatest improvement with increasing subsample size was observed between fixed counts of 100 and 200 individuals; detecting impairment, in particular, was not markedly improved with subsample sizes >200 individuals. Supplementing subsamples with a LR search resulted in only very slight improvements in assemblage-environment relationships, but was effective in improving prediction accuracy, particularly for family-level data. However, family-level assemblage-environment relationships and abilities to detect impairment were inferior to genus- and species-level data, regardless of subsample size. Species-level data performed best, primarily because of the large proportion (>20%) of total species belonging to Chironomidae. The potential importance of Chironomidae to wetland bioassessment was further revealed through an evaluation of a tiered-taxonomic approach, which showed that non-Chironomidae family-level data tiered with species-level Chironomidae data produced results very similar to those obtained using genus- or species-level data exclusively. Our results suggest that fixed counts greater than or equal to 200 or integrated fixed-area/fixed-count approaches that consistently obtain a minimum of 200 individuals should be considered as minimum subsample sizes for wetlands. We additionally advocate LR searches and recommend genus- or species-level taxonomy, particularly for the Chironomidae.

AN - 18376331; 5362771 AB - The recent paper by Roy et al. (2001) presents a compelling relationship between range limit shifts, climatic fluctuations, and body size for marine bivalves in the fossil record. However, their extension of body size as a correlate for contemporary marine bivalve introductions is problematic and requires further scrutiny. Unlike their analysis of the fossil assemblage, the approach used for contemporary invasions does not adequately control for dispersal mechanism (vector) or source region. First, their analysis included mariculture species, intentionally introduced because of their large size, creating a vector-specific bias. Second, successful invaders from multiple source regions (Northern Hemisphere) were compared with potential invaders from a single source region (north-eastern Pacific), leaving both source and vector as uncontrolled variables. We present an analysis of body size for bivalve introductions from a single vector and source region, indicating no correlation between body size and invasion success when eliminating intentional introduction, source region and transport vector as confounding factors.

On the mainland, both species showed evidence of considerable gene flow over huge distances. The island populations, however, revealed significant genetic divergence across some, but not all, ocean passages. Despite the phylogenetic relatedness and broadly similar ecologies of these two butterflies, their intraspecific biogeography clearly differed. Phylogenetic analyses of mitochondrial DNA sequences revealed that populations of D. iulia north of St. Vincent are monophyletic and were probably derived from South America. By contrast, the Jamaican subspecies of H. charithonia rendered West Indian H. charithonia polyphyletic with respect to the mainland populations; thus, H. charithonia seems to have colonized the Greater Antilles on at least two separate occasions from Central America. Colonization velocity does not correlate with subsequent levels of gene flow in either species. Even where range expansion seems to have been instantaneous on a geological timescale, significant allele frequency differences at allozyme loci demonstrate that gene flow is severely curtailed across narrow ocean passages. Stochastic extinction, rapid (re)colonization, but low gene flow probably explain why, in the same species, some islands support genetically distinct and nonexpanding populations, while nearby a single lineage is distributed across several islands. Despite the differences, some common biogeographic patterns were evident between these butterflies and other West Indian taxa; such congruence suggests that intraspecific evolution in the West Indies has been somewhat constrained by earth history events, such as changes in sea level.

Race winners can earn their owners up to $15,000 in a race, and are therefore trained and managed like thoroughbreds. Although they are intuitively directional, birds benefit from training in familiar terrain, as well as from food and companionship incentives. Much of the activity centers around the Boro Park Homing Pigeon Club (1924) in New York, where races are organized and rules codified. The sport appeals to many immigrants who live in the inner city, where homing pigeons can be cared for on a roof hutch.

Given reasonable assumptions about the isotopic composition of Cretaceous seawater, our results suggest that middle bathyal water temperatures at Blake Nose increased from approximately 12 degrees C in the late Albian through middle Cenomanian to a maximum of 20 degrees C during the latest Cenomanian and earliest Turonian. Bottom waters were again approximately 12 degrees C during the middle Campanian and cooled to a minimum of 9 degrees C during the Maastrichtian. Correlative middle bathyal foraminifera from other ocean basins yield paleotemperature estimates that are very similar to those from Blake Nose. Comparison of global bottom-water temperatures and latitudinal thermal gradients suggests that global climate changed from a warm greenhouse state during the late Albian through late Cenomanian to a hot greenhouse phase during the latest Cenomanian through early Campanian, then to cool greenhouse conditions during the mid-Campanian through Maastrichtian.

This radiation is nested phylogenetically within a living species, the Canada goose (Branta canadensis) and is related most closely to the large-bodied lineage within that species. The barnacle goose (Branta leucopsis) is also nested within the Canada goose species and is related most closely to the small-bodied lineage of Canada geese. The peripheral isolation of the barnacle goose in the Palearctic apparently allowed the evolution of its distinctive plumage pattern, whereas the two Nearctic lineages of Canada geese share a primitive plumage pattern. The Hawaiian lineage of Canada geese diverged more dramatically, splitting into at least three species that differ in body size, body proportions, and flight ability. One fossil species, limited to the island of Hawaii, was related closely to the nene but was over four times larger, flightless, heavy-bodied and had a much more robust cranium. Application of a rate calibration to levels of DNA divergence suggests that this species evolved on the island of Hawaii in less than 500,000 years. This date is consistent with the potassium/argon-based age of the island of Hawaii of 430,000-500,000 years. The giant Hawaii goose resembles the moa-nalos, a group of massive, extinct, flightless ducks that lived on older Hawaiian Islands and thus is an example of convergent evolution of similar morphologies in island ecosystems.

Franco-Tsuga heterophylla (Raf.) Sarg. (Douglas-fir-western hemlock) stands in the central Cascades of southern Washington to determine how stand structure and age affect the forest light environment. The shape of the mean transmittance profile was related to stand height, but height of mean maximum transmittance was progressively lower than maximum tree height in older stands. The vertical rate of attenuation declined with stand age in both the overstory and understory. A classification of vertical light zones based on the mean and variance of transmittance showed a progressive widening of the bright (low variance and high mean) and transition (high variance and rapid vertical change) zones in older stands, whereas the dim zone (low variance and mean) narrowed. The zone of maximum canopy surface area in height profiles, estimated by inversion of transmittance profiles, changed from relatively high in the canopy in most young stands ("top-heavy") to lower in the canopy in older stands ("bottom-heavy"). In the understory, all stands had similar mean transmittances, but the spatial scale of variation increased with stand age and increasing crown size. The angular distribution of openness was similar in all stands, though the older stands were less open at all angles than the younger stands. Understory openness was generally unrelated to transmittance in the canopy above. Whole-canopy leaf area indices, estimated using three methods of inverting light measurements, showed little correspondence across methods. The observed patterns in light environment are consistent with structural changes occurring during stand development, particularly the diversification of crowns, the creation of openings of various sizes and the elaboration of the outer canopy surface. The ensemble of measurements has potential use in distinguishing forests of differing ages that have similar stature.

Analyses of mitochondrial sequence variation throughout the distribution reveal substantial phylogeographical structure within N. fuscipes. The major mitochondrial lineages are largely concordant with previously identified morphological subdivisions within the taxon. The geographical distribution of distinct clades suggests that a combination of topographic barriers and the expansion and contraction of suitable habitat during the past 2 million years, especially along particular mountain ranges, have played a major role in the diversification of N. fuscipes. Furthermore, relatively low levels of genetic variation across the northern half of the distribution suggest that dusky-footed woodrats may have only recently expanded into this region.

The freshwater outflow of the Amazon basin is recognized as a major barrier that produces a break between Brazilian and Caribbean faunas. The vast oceanic distances between Brazil and the mid-Atlantic ridge islands represent another formidable barrier. To assess the relative importance of these barriers, we compared a fragment of the mitochondrial DNA (mtDNA) cytochrome b gene among populations of three species of Atlantic surgeonfishes: Acanthurus bahianus, A. chirurgus and A. coeruleus. These species have similar life histories but different adult habitat preferences. The mtDNA data show no population structure between Brazil and the mid-Atlantic islands, indicating that this oceanic barrier is readily traversed by the pelagic larval stage of all three surgeonfishes, which spend ~45-70 days in the pelagic environment. The Amazon is a strong barrier to dispersal of A. bahianus (d = 0.024, Phi sub( ST ) = 0.724), a modest barrier for A. coeruleus ( Phi sub( ST ) = 0.356), and has no discernible effect as a barrier for A. chirurgus. The later species has been collected on soft bottoms with sponge habitats under the Amazon outflow, indicating that relaxed adult habitat requirements enable it to readily cross that barrier. A limited ability to use soft bottom habitats may also explain the low (but significant) population structure in A. coeruleus. In contrast, A. bahianus has not been collected over deep sponge bottoms, and rarely settles outside shallow reefs. Overall, adult habitat preferences seem to be the factor that differentiates phylogeographical patterns in these reef-associated species.

The ditches are maintained by old families, governed by tradition as well as water law. Rights to the water are inherited and sold, and are integral to the value of the surrounding land. Every member of the acequia collective owns a share of water relative to the amount of land owned; these shares represent irrigation rights on designated days.

We present quantitative estimates of beta-diversity for tropical trees by comparing species composition of plots in lowland terra firme forest in Panama, Ecuador, and Peru. We compare observations with predictions derived from a neutral model in which habitat is uniform and only dispersal and speciation influence species turnover. We find that beta-diversity is higher in Panama than in western Amazonia and that patterns in both areas are inconsistent with the neutral model. In Panama, habitat variation appears to increase species turnover relative to Amazonia, where unexpectedly low turnover over great distances suggests that population densities of some species are bounded by as yet unidentified processes. At intermediate scales in both regions, observations can be matched by theory, suggesting that dispersal limitation, with speciation, influences species turnover.

The latter view is corroborated by Goddard's Unami, Munsee, & Meskwaki (Fox) consultants, who explain unexpected animates in terms of talking about things as if they were alive, & is supported by patterns of gender shift from inanimate to animate in narratives & resistance to such shifts in Meskwaki, the only Algonquian language that retains gender marking on singular nouns; new evidence of shifts from animate to inanimate gender; stems with gender contrasts; & the use of the inanimate as an unmarked gender with collectives & indefinites. 1 Appendix, 36 References.

AN - 62198869; ED475289 AB - This book focuses on documenting and understanding the nature of environmental changes observed by indigenous residents of the Arctic. Common themes include increasing variability and unpredictability of the weather and seasonal climatic patterns, as well as changes in the sea ice and the health of wildlife. Nine papers focus on these changes, their impact on indigenous communities, the growing collaboration between communities and environmental researchers, and utilization of findings in community workshops and school classes. Chapters are: "These Are Things That Are Really Happening: Inuit Perspectives on the Evidence and Impacts of Climate Change in Nunavut" (Shari Fox); "Community Contributions to Ecological Monitoring: Knowledge Co-Production in the U.S.-Canada Arctic Borderlands" (Gary Kofinas); "We Can't Predict the Weather Like We Used to: "Inuvialuit Observations of Climate Change, Sachs Harbour, Western Canadian Arctic" (Dyanna Jolly, Fikret Berkes, Jennifer Castleden, Theresa Nichols); "Coastal Sea Ice Watch: Private Confessions of a Convert to Indigenous Knowledge" (David W. Norton); "Watching Ice and Weather Our Way: Some Lessons from Yupik Observations of Sea Ice and Weather on St. Lawrence Island, Alaska" (Igor Krupnik); "Nowadays It Is Not the Same: Inuit Qaujimajatuqangit, Climate and Caribou in the Kitikmeot Region of Nunavut, Canada" (Natasha Thorpe, Sandra Eyegetok, Naikak Hakongak); "Travelling with Fred George: The Changing Ways of Yup'ik Star Navigation in Akiachak, Western Alaska" (Claudette Bradley); "Climate Change and Health in Nunavik and Labrador: Lessons from Inuit Knowledge" (Christopher M. Furgal, Daniel Martin, Pierre Gosselin); "Putting the Human Face on Climate Change through Community Workshops: Inuit Knowledge, Partnerships, and Research" (Scot Nickels, Christopher Furgal, Jennifer Castleden, Pitseolalaq Moss-Davies, Mark Buell, Barbara Armstrong, Diane Dillon, Robin Fonger); and "Epilogue: Making Sense of Arctic Environmental Change?" (Fikret Berkes). The appendix, "Indigenous Views on Climate Change: A Circumpolar Perspective" (Tero Mustonen), describes Snowchange, a multi-year education-oriented project to document indigenous observations of climate change in northern Finland.

AN - 62163759; ED480595 AB - Intended for use in elementary and high school education, this Web site includes a teacher's guide and three lesson plans. The site contains images of museum specimens, scientific drawings, and field photos of the plant and animal species observed by Meriwether Lewis and William Clark, along with journal excerpts, historical notes, and references for many of these examples as well as the date and location of observation. The site may be searched by species groups (mammals, plants, birds, fish, reptiles, amphibians), by location (interactive map, the collection, or search), or by date (interactive map-timeline, or the collection). The "Resources" section includes suggestions for teachers as well as links to sites to Web sites with additional information about the plant and animal species. The teacher's guide provides ideas to get students immersed in U.S. history, geography, social studies, and the natural world at the beginning of the 19th as well as the 21st century.

But the conditions under which pre-emption would be undertaken remain unclear. Military action against terrorist groups, such as al-Qaeda, enjoys broad international legitimacy, but that consensus breaks down over the use of force against a state violating nonproliferation norms. A comparative analysis of historical cases reveals force to be as problematic as its nonmilitary alternatives. Inadequate intelligence, concern over collateral damage to civilian populations, & the fear of triggering a broader conflict have been major constraints on the use of force to prevent the proliferation of weapons of mass destruction. In the post-11 September (2001) era, pre-emption should be a rarely invoked policy option, & successful prevention strategies, employing nonmilitary instruments, might forestall the need to resort to it.

The (super 87) Sr/ (super 86) Sr ratios are particularly appropriate for such provenance investigations, because the White Nile drains predominantly crystalline basement rocks, whereas the Blue Nile and Atbara flow off the Ethiopian Highlands, which consist of Tertiary volcanic rocks. A high-resolution profile of (super 87) Sr/ (super 86) Sr and Ti/Al ratios from a well-dated core in the Nile Delta shows a close correspondence with known changes in Nile flow over the past 7000 yr. At times of higher river flow there was markedly decreased input of Blue Nile-derived and total sediment. This change was caused by northward movement of the Inter Tropical Convergence Zone, resulting in increased vegetative cover in the Ethiopian Highlands due to higher rainfall and a longer wet season. This inverse relationship between Nile River flow and sediment flux may have had important implications in the development of agricultural technology in ancient Egypt. The marked minimum in (super 87) Sr/ (super 86) Sr at 4200-4500 yr B.P. is coincident with the end of the Old Kingdom in Egypt and provides independent evidence that demise of the Old Kingdom might have been associated with an extended period of catastrophic low floods. During the Quaternary and late Neogene, there was periodic deposition of organic-rich sediments (sapropels) in the eastern Mediterranean that represent important indicators of major environmental change. Evidence from the Ti/Al ratio suggests that the pattern of erosion and sediment supply from the Nile catchment observed in this study also occurred throughout much of the Neogene and Quaternary. The reduced inputs of Blue Nile sediment during times of sapropel formation contributed to the increased primary productivity by reducing the amount of phosphate removed on particles and to the observed change to N limitation in the eastern Mediterranean, which are important characteristics of sapropel deposition.

The 720 observations of density for each taxon were analyzed by General Linear Models with density as the dependent variable. Differences among stations, years, seasons and their interactions are all significant. When treated as covariates environmental variables contributed little to explaining the observed variability in densities. However, the observed densities of the taxa are highly correlated and when a single taxon is treated as a covariate most of the variability in the density of a related taxon is explained. There are no significant differences among replicates (taken within a square meter) or their interactions. Consequently, the biotic or abiotic factor(s), although unknown, responsible for the simultaneous density variation of the taxa operate on a relatively small spatial scale. Based on these observations and previous studies, we propose a model wherein individual foraminifers are spatially distributed as a heterogeneous continuum forming patches with different densities that are only meters apart; reproduction is asynchronous causing pulsating patches that vary in space and time. Thus, we would expect significant differences among stations, years, seasons and their interaction. At the same time, no long-term increase or decrease in density for any of the taxa is observed. Evidently, long-term stability is achieved through considerable short-term variability in space and time. Although observations at a single station are not indicative of a larger area at any particular time, the concept of pulsating patches indicates that observations at a station will in the long-term give an assessment of a larger area.

Here we review work over the past decade that defines the probable causes of the mass extinction, and evaluate several extinction hypotheses. The marine extinctions were selective; epifaunal suspension feeders were more affected than other clades, although significant variations occurred even among the filter feeders. In southern China, the Changhsingian marine extinction was nearly catastrophic, occurring in <0.5 m.y. On land, vertebrates, plants, and insects all underwent major extinctions. The event coincides with (1) a drop of delta (super 13) C in carbonates, from approximately +2 per mil to -2 per mil in both marine and terrestrial sections; (2) the eruption of the massive Siberian continental flood basalts; and (3) evidence of shallow-water marine anoxia, and perhaps deep-water anoxia. Although the cause of the extinction remains unclear, a series of constraints on speculation have been established in the past few years. Leading contenders for the cause are the climatic effects, including acid rain and global warming, possibly induced by the eruption of the Siberian flood basalts; and marine anoxia. An extraterrestrial impact is consistent with the geochronological and paleontological data from southern China and elsewhere, and some possible evidence for impact has recently been advanced.

Both the bracketing pelagic ooze and the ejecta bed are undisturbed at Site 1049, allowing detailed examination of the expression of the boundary event in an open ocean setting. The youngest Cretaceous sediments contain a diverse assemblage of well-preserved upper Maastrichtian Tethyan microfossils. The overlying ejecta bed varies laterally in thickness, has sharp lower and upper contacts, and contains features (e.g., presence of a foraminiferal grainstone layer at its base and large chalk clasts in its middle, and dominance of poorly sorted coarse grains throughout) that suggest it was deposited by one or several mass-flow events. The oldest Danian ooze contains abundant, tiny planktonic foraminifera characteristic of the early Danian Palpha Zone as well as common, large Cretaceous individuals. The lowermost Danian P0 Zone (assemblage dominated by Guembelitria cretacea) is apparently absent. This absence could reflect restriction of the P0 assemblage to shallower settings, slow sedimentation rates coupled with bioturbation mixing Tertiary forms into (and thus obscuring) the P0 Zone, or an interval of erosion or nondeposition. Cretaceous species decline and last occur in the first several meters of section above the ejecta bed. This pattern could be interpreted as evidence for gradual extinction above the impact bed, but thin-section observations, relative abundance counts, size-distribution analyses, and comparison with species extinctions at other K-T sections demonstrate sudden extinction, nearly all post-K-T occurrences of Cretaceous planktonic foraminiferal species being explained as the result of sediment reworking.

The time duration of this interval is approximately 2.2 m.y., 1.4 m.y. of which is latest Cretaceous. These data originate from 80 localities from the Williston Basin of southwestern North Dakota and are allocated to four assemblage zones consisting of 385 megafloral morphotypes of bryophytes, ferns, conifers, cycads, Ginkgo, monocots, and 333 dicots. All 49 foliar damage types were produced by external foliage feeding, mining, galling, and piercing and sucking insects, each of which was assigned one of the following host specificity levels: generalized, intermediate, or specialized. A distinctive pattern emerged when these damage types were plotted stratigraphically: of the 22 damage types that survive the Cretaceous-Tertiary boundary (K-T), 55% are generalized; of the 15 damage types that are extinguished immediately below the boundary, all are specialized or intermediate, as are the 12 damage types that disappear in stepped fashion somewhat before the boundary. Within this interval only two damage types are unique to the Fort Union Formation, occurring during the lowest Paleocene. These data indicate that highly and moderately specialized associations were preferentially culled at the K-T boundary, disproportionately enriching early Paleocene floras in generalized herbivores as dominant colonizers. These data are local, and the Signor-Lipps effect may partially obscure the true pattern, thus restricting extrapolation to the Western Interior of North America. Nevertheless, (1) the selective extinction of specialist herbivores at the boundary, (2) the absence of significant evidence for immigrant colonization, (3) the prolonged occurrence of species-depauperate floras during the Paleocene, and (4) the high percentage of last occurrences at and not before the boundary, despite the Signor-Lipps effect, suggest a role for end-Cretaceous abiotic perturbation and consequent biotic response in the evolution of modern plant and insect associations.

The morphological and textural similarities of volcanic debris-avalanche deposits to those of nonvolcanic landslides facilitated their recognition, but there are also significant differences between the two landslide varieties. Volcanic landslides are often larger (by two or more orders of magnitude) and are substantially more mobile than nonvolcanic landslides. This reflects factors including the mobility-enhancing influence of volcanic fluids, gases, and explosions, and material properties effects such as the greater component of fragmental materials that form volcanoes. Failure planes of volcanic landslides are typically substantially deeper than those of nonvolcanic landslides, often reaching 1-2 km depth. Large-scale edifice failure occurs at volcanoes ranging from 10 000 km (super 3) in size. Typically 100 km) at velocities that may approach 100 m/s, covering areas of 1000 km (super 2) . Morphology, textures, and emplacement mechanisms vary with water content; avalanches can be relatively dry, or sufficiently wet to transform into lahars. In addition to hazards from the avalanches, landslides from coastal volcanoes have produced tsunamis; volcanic landslides can trigger, or be accompanied by, eruptions that produce hazards from lateral blasts, Plinian explosions, pyroclastic flows, and lahars.

The energy of the impact will be a function of the mass of the asteroid and its impact velocity. The mass of an asteroid is very difficult to determine from Earth. One way to derive a near-Earth object's mass is by estimating the object's density from its surface composition. Reflectance spectra are the best way to determine an object's composition since many minerals (e.g. olivine, pyroxene, hydrated silicates) have characteristic absorption features. However, metallic iron does not have characteristic absorption bands and is very hard to identify from Earth. For a particular size, asteroids with compositions similar to iron meteorites pose the biggest impact threat since they have the highest densities, but they are expected to be only a few percent of the impacting population. Knowing an asteroid's composition is also vital for understanding how best to divert an incoming asteroid.

Sedimentologic, geomorphic, and chronologic evidence indicates that Lakes Lahontan and Columbus-Rennie were as much as 70 m higher at about 650 thousand years ago (Ka) than during their late Pleistocene highstands. At its former altitude of 1400 m, Lake Lahontan submerged present-day Reno, Carson City, and Battle Mountain in Nevada and flooded other now-dry basins. To the east, Lakes Jonathan (new name), Diamond, Newark, and Hubbs reached highstands during the early-middle(?) Pleistocene that were 25-40 m above their late Pleistocene shorelines; at these very high levels, the lakes became temporary or permanent tributaries to the Humboldt River and, hence, to Lake Lahontan. This scenario presents a startling vision of a western Great Basin in which climatic and tectonic effects conspired to integrate presently isolated basins into one enormous drainage system during at least one brief period during the Quaternary. Such a temporary connection could have permitted fish to migrate from the Humboldt River southward into the presently isolated Newark Valley and from Lake Lahontan into Fairview Valley. The timing of drainage integration provides suggested maximum ages for fish to populate the basins of Lake Diamond and Lake Jonathan. The Walker Lake subbasin of Lake Lahontan held deep lakes at least four times during the early Pleistocene; these were at least 15-25 m above the Sehoo highstand. One site on the Humboldt River in the northeastern Lahontan Basin displays exposed, faulted lake sediments of early Pleistocene age that are now 40-55 m above the Sehoo limit. These sediments suggest that the northern and Walker Lake subbasins were contiguous parts of Lake Lahontan by about one million years ago (Ma), but fish fossils indicate that drainage connections existed before 1 Ma. For example, high beach deposits suggest that Lake Russell, now a tributary to the Owens River, previously overflowed to the Walker River, potentially providing a migration route for fish southward along the east side of the Sierra Nevada into the Owens River system. Deposits of Pliocene lakes suggest connections existed among proto-Lakes Lahontan, Columbus-Rennie, Clayton, and possibly Tonopah. Tephrochronologic ages of these Pliocene lakes provide constraints on the availability of aquatic migration routes at different times. Reconstructing and dating these lake levels also has important implications for paleoclimate, tectonics, and drainage evolution in the western Great Basin. For example, shorelines in several basins form a stair-step sequence downward with time from the highest levels, thought to have formed at about 650 Ka, to the lowest, formed during the late Pleistocene. This descending sequence indicates progressive drying of pluvial periods, possibly caused by uplift of the Sierra Nevada and other western ranges relative to the western Great Basin. These effects, however, cannot account for the extremely high lake levels during the early-middle Pleistocene; rather, these high levels were probably caused by a combination of increased effective moisture and changes in the size of the Lake Lahontan drainage basin.

Radiocarbon dating of black lacustrine muds and uranium-series dates on shoreline tufas later established that permanent lakes occurred in Death Valley during at least two different periods: marine oxygen isotope stage 2 (26 thousand to about 10 thousand years ago (Ka)) and marine oxygen isotope stage 5e/6 (>200 to approximately 120 Ka). The sources of inflow water to Death Valley during wet pluvial periods were the Amargosa River, the Owens River system, and the Mojave River. The timing of spillover from the Owens River system via Panamint Basin into Death Valley is still uncertain; inflow from the Mojave River is interpreted to have occurred during the last 18 Ky, but more precise timing and the significance of the Mojave River inflow is unknown. A borehole core (DV93-1) taken from Badwater Basin, Death Valley, in 1993, is composed of interbedded salts and muds. Core DV93-1 contains a 186 m long, 200 thousand years (Ky) record of closed-basin paleoenvironments and paleoclimates, which is interpreted on the basis of sedimentology, ostracode assemblages, homogenization temperatures of fluid inclusions in halite. The lacustrine sediments in core DV93-1 correlate with dated shoreline tufa. The 200 Ky paleoclimate record is dominated by two cycles of dry and/or warm conditions followed by wet and cold conditions that occurred on a 100 Ky time scale. Of significance are the major lacustrine phases of 35-10 Ka and 186-120 Ka (marine oxygen isotope stages 2 and 5e/6, respectively), which represent dramatically colder and wetter conditions than those of modern Death Valley. Of the two major lake periods, the penultimate glacial lakes were deeper and lasted far longer than those of the last glacial.

I review herein the rich late-Pleistocene and Holocene small-mammal record recently obtained from Homestead Cave in the northern Bonneville Basin, Utah. Together with a diverse variety of other small-mammal sequences, this record indicates that the early Holocene (ca. 10,000-7500 years B.P. (before present) climate of the northern Great Basin was cool and moist, not warm and moist as has been argued on the basis of computer modeling. This sequence also demonstrates the substantial effects of the generally hot and dry climate of the middle Holocene (ca. 7500-4500 years B.P.) on small mammals in this area as well as the responses of those mammals to the end of this period. Perhaps most surprisingly, Homestead Cave data document the local extinction and recent recolonization of a species that was at one time felt to be isolated on Great Basin mountains. This discovery joins newly available neoecological data in showing that the history of "montane" mammals in the Great Basin is far more complex than once had been thought, and it implies that low-elevation dispersal corridors must be provided in conjunction with the creation of mountain-based wildlife reserves in the Great Basin.

During the last deep-lake cycle, but before and after their period of integration with the major water body, isolated closed-basin lakes existed in many of those subbasins. This study focuses on two of Lake Bonneville's seven major subbasins, Puddle Valley and Tule Valley, because they display distinctive geomorphic and sedimentologic evidence of the subbasin integration process. In both cases, Lake Bonneville burst through material at the dividing threshold, and water poured into the adjoining subbasin as a fluvial current of high discharge. Where the jet spread out onto the subbasin's piedmont, it deposited a gravel expansion bar over which gravel was transported in large-scale subaqueous bedforms. Fluvial braid bars in their initial stage of development provide a good analogue for the general form of the inflow bars and help identify the fluvial processes of inflow-bar formation. Details of the geomorphology and sedimentology of the inflow bars reflect the site-specific conditions under which they formed. The ability to recognize inflow bars in the geomorphic and stratigraphic record will help researchers identify subbasin integration events and will, therefore, contribute to improved accuracy in reconstructing the geomorphic and paleoclimatic history of other paleolake basins.

The principal driving models include (1) Milankovitch-scale (10 (super 6) -10 (super 4) yrs) jet stream migration in response to changes in the sizes of continental glaciers (2) millennial-scale, (10 (super 4) -10 (super 2) yr) climate change as a hemispheric response to large-scale climate changes in the North Atlantic Ocean (i.e., Dansgaard-Oeschger cycles, Heinrich Events, and Bond Cycles), and (3) Antevs' (1948) phenomenological model of climate change in the Holocene, which primarily predicts, on the average, a relatively warm and dry interval in the middle part of the Holocene. Changes in the Earth's orbital geometry are the ultimate causes for Milankovitch-scale climate changes. Changes in the solar constant might prove to be the ultimate cause for climate change with periods long enough to overlap the part of the spectrum occupied by the Holocene changes and by the millennial-scale climate changes; however, the magnitude of change expected from solar processes would be much smaller than those associated with millennial-scale climate changes, so if there is a causal connection, it would have to be strongly nonlinear. Climate records from the northwestern Great Basin, particularly those from pluvial Lakes Modoc, Lahontan, and Chewaucan, support models related to Milankovitch-scale climate changes by exhibiting the appropriate periodicities and/or phases of predicted climate change and by exhibiting the appropriate dynamic spectral content of climate change throughout time (e.g., the change from a dominance of periods lasting 400 thousand years (Ky) and 41 Ky to a dominance of 100 Ky starting at approximately 900 thousand years ago (Ka)). Records of millennial-scale change from the northwestern Great Basin are beginning to appear in the literature, but at the time of this review, no published records have been dated precisely enough for comparison with the archetypical records from North Atlantic marine and ice cores. A collective record associated with pluvial lakes throughout the northwestern Great Basin indicates a weak trend toward overall lower lake levels and warmer, drier climate during the middle Holocene, thereby supporting Antevs' (1948) model of Holocene climate change for the Great Basin.

Winter snows feed river and lakeside marsh systems during the warmer months but inhibit upland occupation by humans in the winter. Throughout their history, Great Basin foraging peoples dealt with this half-wet, half-dry environment in two basic ways. One adaptive pattern focused on a relatively stationary (but not strictly sedentary) lifestyle around the larger marsh systems at the ends of streams and rivers in Great Basin valleys. The other was characterized by the movement of small groups throughout mountain/valley systems in which the marshes were too small to support a stable year-round existence. The former strategy was more common, and likely preferred, because of the year-round availability of storable resources collected primarily by women. Late Quaternary fluctuations of Great Basin lakes, particularly those that occurred during periods of rapid climate change, had a tremendous effect on Great Basin foragers because of their focus on lakeside marsh resources. Early in the prehistoric sequence, when lakes were relatively high, foraging was focused on lakeside environments. When lakes began to dry up during the middle Holocene, mobile foraging became more common. By the late Holocene when lakes rebounded to some extent, increasing population levels resulted in the widespread use of both adaptive strategies.

Although the region was visited by fur trappers and mountain men in the 1820s and 1830s, it was not until the 1840s that the European pathfinders and empire builders tarried to explore the woodland-covered mountains and playa-bottomed valleys of the Great Basin. Mormon farmers and spirited miners settled this wild land, uprooting the native people who had lived there for millennia. As the region opened to European settlement, evidence of a long and complex environmental history was discovered and explored. But as recently as 50 years ago our knowledge of Late Quaternary lake histories and climates was minimal, and our knowledge of the dynamics of Pleistocene and Holocene vegetation was virtually nonexistent. Our understanding has advanced dramatically in the last half century, with advances in analyses of pollen, woodrat middens, and tree rings. A substantial pollen and plant macrofossil database has been assembled, spanning tens of thousands to hundreds of thousands of years, such that our knowledge of Late Quaternary vegetation history in the Great Basin rivals that of any other region in the world. These data, coupled with the long-term lake histories deduced from the basins of the Lahontan, Bonneville, Chewaucan, and Owens-to-Death Valley lake systems, permit detailed examination of late Pleistocene vegetation dynamics in relation to aquatic system history. By examining proxy records from the various subregions of the Great Basin and the northern Mojave Desert, we have compiled a compelling picture of past climate and the vegetation and hydrologic responses during the last 50,000-150,000 years.

K. Gilbert and Ernest Antevs AN - 51961588; 2003-055683 AB - The careful observations and eloquent writings of Grove Karl Gilbert in the late 1800s laid the framework for most subsequent studies of lacustrine history in the Bonneville Basin. By the time of the 1942 symposium on the glacial and postglacial history of the Great Basin, his work had been largely unchallenged by the scientific community. Ernst Antevs, who participated in that symposium, reinterpreted some of Gilbert's observations and contributed both a global perspective and a hypothesis involving atmospheric circulation to studies of Lake Bonneville and other Great Basin Quaternary lakes. Fifty years after the 1942 symposium, the contributions of Gilbert and Antevs are still at the core of state-of-the-art research on Great Basin Quaternary lakes.

They investigated spatial and temporal barriers that permitted evolutionary divergence of fishes. They also used fish evidence to identify the locations and possible timings of past aquatic connections among basins. Hubbs and Miller focused on morphological differences among fish populations in related basins and hypothesized that their evolutionary divergence occurred over only hundreds to thousands of years. Their conclusions depended upon the assumption that divergence began after the most recent time of homogeneous ancestral populations, which was assumed to be the time of closure of the most recent hydrographic connection. This approach and its key assumptions are standard in studies of evolutionary rates, but they require reexamination. Our data suggest that rates of morphological change in oligogenic and ecophenotypic traits of Great Basin fishes may be rapid in the short term (thousands of years), but Miocene to Pleistocene fossils of western North American fishes indicate slow changes over millions of years. Tests of hypotheses about evolutionary rates require independent estimates of both time and degree of divergence. Our evolutionary-rate estimates are based upon regression of percent sequence divergence (of mitochondrial DNA) between pairs of lineages against millions of years of divergence of sister clades, estimated from dates of first appearances in the fossil record. The results indicate rates of molecular evolution in the range of approximately one-half percent (salmonids) to one percent (cyprinids and cyprinodonts) sequence divergence per one million years. The ages of some forms thought to represent ten thousand years of postpluvial evolution are more likely to be hundreds of thousands of years old, according to molecular/fossil estimates. Estimated divergence times of fishes, based upon DNA, provide unique data on the nature and timing of barriers and aquatic connections among basins. Great Basin fish faunas exhibit high endemism, but they have lower diversity than predicted by pluvial cycles of isolation and by rapid evolution in allopatry. We hypothesize that uplift causes high stream gradients and, therefore, decreased local habitat diversity because of rapid stream runoff. Small and isolated populations on the basin floors are prone to allopatric differentiation, but they also are prone to high extinction rates; therefore, isolation and stabilizing selection in desert basins rarely produced new species that survived extinction events.

These analyses and other pollen diagrams from the region generally record elevated percentages of forest conifers (pine, spruce, fir, and Douglas fir) during the last two pluvials: 24-14.5 (super 14) C Ky B.P. (radiocarbondated, thousand years before present) and approximately 150-130 Ka (thousand years ago). The regional vegetation was a mosaic of cold-dry pine woodland and sagebrush steppe. This mosaic was replaced by steppe vegetation 10.8 (super 14) C Ky B.P., with xeric indicators reaching maximum percentages 7-5 (super 14) C Ky B.P. Similarly, pluvial Lake Bonneville was at about the Gilbert Lake level from 87 to 24 Ka, except for a dry interval approximately 70 Ka, and it was above the Gilbert level from 24 to 14.5 (super 14) C Ky B.P. It then fell below the Gilbert level (i.e., it did not occupy the Wendover Basin) except for brief periods after 11,300+ or -300 (super 14) C years B.P. Pollen analysis of sediments provided by the Amoco Production Company indicated that the upland vegetation (nonriparian, nonlittoral) has been desert from the late Miocene to the present. Estimated temperature was highest and moisture least during the Pliocene, with temperatures cooling and moisture increasing there-after. The late Miocene (<5 Ma) was dominated by pollen of xerophytic Sarcobatus and Ephedra, which was replaced by Chenopodiaceae-Amaranthus and Artemisia pollen during the Pliocene and early Pleistocene (5-0.75 Ma). After 0.75 Ma, percentages of Artemisia and Pinus abruptly increase. Three noteworthy events punctuate the gradual evolution of the desert flora: a warm-cold oscillation 3.7 Ma, a cold interval 2.6 Ma, and abrupt cooling after 0.75 Ma. Pluvial-interpluvial cycles begin after the 0.75 Ma event, each with an average length of 0.1 million years. Diversion of the Bear River into the Great Salt Lake basin is indicated by increased pollen concentration after 0.31 Ma, near the oxygen isotope stage 8-9 transition.

This interval is associated with a significant increase in plant diversity in temperate latitudes. However, data from tropical regions remain largely unknown. The record of pollen and spore diversity across the late Paleocene to the early middle Eocene of eight sections in central and eastern Colombia was analyzed. Several techniques, including range-through method, rarefaction, bootstrap, detrended correspondence analysis, and Shannon index, were used to assess the significance of the observed diversity pattern. The palynofloral record indicates that the lower to middle Eocene contains a significantly higher palynofloral diversity than the underlying upper Paleocene strata. This pattern is maintained after accounting for sample size, number of samples/time unit, lithofacies, and depositional systems. Eocene palynofloras have higher alpha and beta diversities and a higher equitability than Paleocene palynofloras. This increase in diversity is the product of a gradual increase in the rate of first appearances and a gradual decrease in the rate of last appearances. The early to middle Eocene increase in diversity, as well as the increase in spore abundance and diversity, suggests that tropical (equatorial) climate became wetter during the early to middle Eocene. This interpretation favors causes for early Eocene warming that do not involve significant increases in greenhouse gases. Samples from strata associated with the Paleocene/Eocene thermal maximum were barren for palynomorphs, and the effects of this climatic event on tropical vegetation remains uncertain.

These lesions were imaged with both plain film radiography and computed tomography. Appearance of the rib lesions is consistent with fracture-callus formation. Two lumbar vertebrae exhibit vertebral spondylosis, which manifests itself as mild exostosis and lipping that does not involve the articular surfaces. These two pathologies are common findings in osteological collections of Holocene cetaceans. Such lesions are especially common among individuals that have reached skeletal maturity; however, this individual is skeletally immature. The mandibular lesions consists of extensive periosteal new bone formation caudal to the tooth row, on the lateral aspect of the right mandibular ramus. Two large drainage fistulae are present, one of which reveals a bony sequestrum. New bone formation may result either from neoplastic or infectious processes-the etiology of the lesion appear to be infectious, possibly as a result of bacterial infection secondary to trauma. Mandibular osteomyelitis of this sort does not appear to be common in odontocetes, and new bone formation to this extent likely would have compromised echolocation. The combination of chronic infection and reduced echolocation abilities may have led directly to the demise of this individual.

The diagnoses of the subfamily Monachinae and the genus Pontophoca are emended to include the postcranial characters. Pontophoca, as revised, is proposed as the sister group of the modern Monachus and is included in the monophyletic subfamily Monachinae. We also include in this subfamily two extinct taxa that occur in both the eastern United States and western Europe: Callophoca and Pliophoca.

It shows a mixture of subfamilial characters. Features shared with Phocinae are the number of incisors and the lack of a strongly pronounced mastoid process. Characters similar to Monachinae are the shape of maxillae and the ratio between frontal and maxillary contacts of nasal bones. Characters shared with Cystophorinae are the ratio between interorbital width and mastoid width and (also shared with Phocinae) the ratio between length of auditory bullae and distance between them. Moreover, this skull has primitive features that are not known in any of the three subfamilies: M1 is triangular, with three cusps and three roots; in P2-P4 the larger posterior roots are clearly made up of two fused roots; the incisors form a curved line; the anterior palatal foramina are deep and oval; and the sagittal crest is very well developed. The traditional separation of the family Phocidae into the sub-families Phocinae, Monachinae, and Cystophorinae has been intensively debated during the past 40 years and debate continues today, but we herein follow the traditional classification. The plesiomorphic D. claytoni is thus considered a sister taxon to the three extant subfamilies of Phocidae and is referred to a new subfamily, Devinophocinae. Because of its late age, D. claytoni cannot be ancestral to the more advanced phocids. Its primitive characters in combination with the characters it shares with the other subfamilies suggest, however, that it might approximate the common ancestral morphotype.

Although each species is known only by a single braincase without a rostrum, both have been understood to be baleen-bearing, archaic mysticetes of the extinct family Cetotheriidae. Fossil baleen whales of this age are generally rare worldwide, and no Oligocene cetotheriids have been named previously from the eastern coast of North America. Elsewhere, we have established the family Eomysticetidae to accommodate two very primitive new mysticetes from the late Oligocene Chandler Bridge Formation near Charleston, South Carolina (Sanders and Barnes, 1999, 2002). In addition, two mysticete braincases without rostra from the underlying Ashley Formation near Charleston represent a new genus and new species in the Cetotheriidae. These specimens document a new taxon that is markedly different from Cetotheriopsis and is herein named Micromysticetus rothauseni, new genus, new species It is most similar to Cetotheriopsis tobieni Rothausen, 1971, which is herein referred to the new genus Micromysticetus. Micromysticetus rothauseni is a significant addition to the diverse Oligocene marine vertebrate assemblages from the Oligocene beds near Charleston. It constitutes the oldest known western North Atlantic records of the family Cetotheriidae and provides additional evidence of the archaeocete ancestry of the mysticetes.

Its cranial specializations are unique among cetaceans and include loss of the elongated rostrum, development of large premaxillary processes housing asymmetrical tusks, forward migration of the bony nares, reversal of the typical cetacean telescoping of the skull, dorsal binocular vision, large vaulted palate, and an inferred upper lip. The structure of the basicranium (possession of palatine expansions of the pterygoid sinus and presence of a large cranial hiatus) and face (possession of a medial portion of the maxillae at the anterior border of the nares) indicates that it belongs to the odontocete infraorder Delphinida and to the superfamily Delphinoidea. Within this group Odobenocetops is related to the Monodontidae because of the lateral lamina of its palatine flooring the optic groove, the anteroposterior elongation of the temporal fossa, and the thickness of the alisphenoid and squamosal in the region of the foramen ovale. We hypothesize that Odobenocetops, like the walrus, fed upon shallow-water benthic invertebrates and probably used its tongue and upper lip jointly in extracting the soft parts of bivalves or other invertebrates by suction. The highly modified morphology of the rostrum indicates that there was no melon as in all other odontocetes, and therefore that Odobenocetops was probably unable to echolocate; binocular vision could have compensated for this inability. The most probable function of the tusks themselves was social, as in the living walrus, but we suggest that the historically primary function of both the premaxillary processes of Odobenocetops and the tusks of Odobenus was as orientation guides in feeding. This reopens the question of whether the tusks of walruses play a role in feeding, as it seems that these also may be useful as orientation guides for the mouth and vibrissal array.

Desmostylians probably had a quadrupedal stance, with the body well off the ground and the limbs more or less under the body; a strongly arched spine and steeply inclined pelvis; slightly abducted elbows and more strongly abducted knees; and a digitigrade foot posture with an extended but not hyperextended wrist and hyperextended toes, the front toes pointing anterolaterad and the hind toes pointing forward. Most peculiarities of the skeleton have parallels in certain large, slow-moving terrestrial mammals, such as ground sloths and chalicotheres. The desmostylian skeleton was apparently well suited to supporting the body's weight on the hindquarters, perhaps while the animal clambered slowly over very uneven ground. This most likely occurred while it foraged for marine algae or sea grasses in rocky intertidal areas of the North Pacific shoreline, and while it crossed these areas en route to and from the water. Locomotion in the water probably resembled that of polar bears, with alternate pectoral paddling as the principal means of propulsion and the hind limbs used for steering. Surprisingly, desmostylian-like features of the tibia and ankle also are found in many other primitive ungulates and deserve closer study.

We confidently assign the specimen, FMNH P14424, to Vassallia maxima Castellanos after comparing it with the mandible and osteoderms of the type of this species and with other material in South American museums. FMNH P14424 is from fossiliferous deposits near Puerta del Corral Quemado, Catamarca Province, Argentina. Field notes are ambiguous with regard to its precise stratigraphic level, and therefore age, but the section from which it was recovered includes both the Huayquerian and the Montehermosan. The range of osteodermal variation of V. maxima FMNH P14424 encompasses that of Plaina intermedia Ameghino and P. subintermedia Rovereto, which suggests that these genera and species may not justifiably be distinguished. If this is confirmed, then Vassallia is the valid genus and V. intermedia (Ameghino, 1888) is the valid specific name for the species; however, until the status of these taxa is unambiguously demonstrated, we maintain V. maxima.

In agreement with previous work, this study confirms that Phascolonus is a part of the clade containing the living hairy-nosed wombat, Lasiorhinus, and other large fossil wombats. Phascolonus retains some plesiomorphies seen only in the Miocene wombats (large, bilobed premolars) but also exhibits a number of autapomorphies of the skull and dentition, the most striking of which are the great breadth of the upper incisors, the peculiar arcuate ectotympanic, and the enclosure of the facial canal within the mastoid process of the periotic.

This relatively large sample includes specimens of different developmental ages and genders and permits documentation of the range of variation in this Miocene pinniped. This variation suggests that several characters previously considered diagnostic of different species are in fact the result of sexual dimorphism. Reevaluation of the status of Desmatophoca supports recognition of only two species, D. brachycephala Barnes, 1987, and D. oregonensis. A cladistic analysis, using 30 cranial and dental characters, supports the monophyly of the genus Desmatophoca and suggests a close sister-group relationship with a monophyletic Allodesmus clade. The parsimony analysis also confirms the monophyly of the Desmatophocidae, which is herein defined as the clade containing the most recent common ancestor of Desmatophoca and Allodesmus and all of its descendants. Phocids are shown to be the sister group to the desmatophocids in a redefined monophyletic Phocoidea.

It also extends the range 280 km north and 65 km east of the previously documented limits for the genus in the western Great Lakes area. The Kenora bison died in a shallow pond in an oak-pine woodland; it was experiencing nutritional stress at the time of its death. Both halves of the mandible had been fractured by trauma earlier in life. A review of morphological change in bison during the Holocene shows that later bison, Bison bison, were absolutely smaller, had absolutely shorter limbs, and had more robust upper limbs and more gracile lower limbs, relative to length, than did the earlier bison, Bison antiquus. Compared with that of Bison antiquus, the thoracic limb of Bison bison became elongated relative to the pelvic limb, and limb length increased relative to skull size. Relative to the norm in Bison antiquus, these traits diverged further in the wood bison, Bison bison athabascae, than in the plains bison, Bison bison bison. The patterns of pelage development and social behavior in Bison bison bison, however, are more distant from parallel patterns postulated for Bison antiquus antiquus than are patterns of pelage development and social behavior in Bison bison athabascae.

The holotype of B. ricei new species consists of a partial skull, partial mandible, all major flipper bones, and representatives of all types of vertebrae, allowing comparison with the two best-known European species. This study, together with the known occurrence of Balaena species in the Pliocene of Europe, strengthens the conclusion that bowhead whales were present on both sides of the North Atlantic Ocean at that time. By contrast, remains of Balaena have not been reported from Miocene deposits of the Atlantic coast of North America.

The species shows many primitive features reminiscent of the archaic odontocete family Agorophiidae: the cheek teeth appear nonpolydont, the nares and premaxillary sac fossae lie anteriorly, the orbit and facial fossa are elevated above the level of the rostrum, the ascending processes of premaxillae are narrow and long, the supraorbital processes of the maxillae are narrow, the intertemporal constriction is prominent, and the pterygoid sinus fossae are restricted to the basicranium. These features are consistent with a basal position among the odontocetes, but they do not justify placement in the paraphyletic- and probably polyphyletic-grade family Agorophiidae. Simocetus rayi shows some unusual autapomorphies (toothless premaxillae, anterior of rostrum anterior of rostrum and mandible downturned) that exclude it from described taxa of odontocetes, and for this reason it is placed in a new and currently monotypic family, Simocetidae. Broader relationships are uncertain; some cranial features hint at affinities with Eurhinodelphinidae. For now, S. rayi is regarded as a specialized archaic odontocete that lies stemward (more basal) to all extant groups of Odontoceti (namely, Physeteroidea, Ziphiidae, Platanistoidea, and Delphinida). Simocetus rayi was perhaps a bottom feeder that preyed through suction feeding on soft-bodied invertebrates. The inferred presence of nasal turbinals and a vomeronasal organ contrasts with the situation in living odontocetes. Features of the face and basicranium point to echolocation abilities comparable to those of extant Odontoceti. Simocetus rayi and other contemporaneous archaic odontocetes from Oregon and Washington indicate that odontocetes were taxonomically and ecologically diverse by the late Oligocene.

A distal section of an upper right incisor and an incisor fragment of the extinct Pleistocene giant beaver, Castoroides, were recovered from Bell Cave, Colbert County, Alabama. Cave ACb-3, also in Colbert County and containing an extensive deposit of late Pleistocene megafauna, yielded a single incisor enamel fragment. A fragment of a left ilium of this beaver was found in a dry stream bed in Ruby Falls Cave, Lookout Mountain, Hamilton County, Tennessee. These four specimens are referred to Castoroides sp. A relatively complete skull of Castoroides has been recovered from the Cooper River, near Strawberry Hill, Charleston County, South Carolina. The cranial characters of this specimen make it referable to Castoroides leiseyorum Morgan and White, 1995, which was described from the Irvingtonian Leisey Shell Pit, Hillsborough County, Florida. The taxonomy of Castoroides from the southeastern United States is uncertain, and at least two different interpretations are possible.

With the exception of the primitive mysticete Micromysticetus rothauseni Sanders and Barnes (2002), all previously named Cetacea from these deposits are odontocetes. Eomysticetus whitmorei, known by much of an associated skeleton, is a baleen-bearing mysticete having rostral features that are characteristically associated with baleen-whale feeding adaptations. The rostrum is relatively broad and flat, the palate has nutrient foramina associated with baleen development, and the dentaries are elongate, oval in cross section, and edentulous. This whale shares many cranial features with Archaeoceti, e.g., the narrow, elongate intertemporal region, narrow supraorbital processes of the frontals, elongate zygomatic processes of the squamosals, and small cochlear portion and narrow anterior process of the periotic. The numbers and structure of the vertebrae and ribs are intermediate between archaeocetes and cetotheriid mysticetes, and the relative length of the humerus compared with that of the distal limb bones (radius and ulna) is intermediate between those of archaeocetes and Neogene mysticetes. A second, more highly evolved species, Eomysticetus carolinensis, described herein, is represented by a partial skull also from the Chandler Bridge Formation. The osteology of Eomysticetidae strongly reinforces the ancestral-descendant relationship of Archaeoceti to Mysticeti and helps to substantiate the theory of the monophyly of the Cetacea. Eomysticetus whitmorei is the most archaic baleen-bearing mysticete yet described and survived into late Oligocene time as a relict form. In its degree of cranial telescoping it is more primitive than the contemporaneous toothed mysticetes of the family Aetiocetidae and contemporaneous baleen-bearing members of the Cetotheriidae. The presence of the second species, E. carolinensis, in the same formation demonstrates the newly recognized evolutionary diversity of the Oligocene Cetacea and the fact that multiple lineages of various groups evolved simultaneously. The family Eomysticetidae is the presumed sister taxon to all of the more-derived baleen-bearing Mysticeti.

J. Horodyski from the Appekunny Formation in Glacier National Park, Montana, and dated at approximately 1.5 giga-annum (Ga), were never formally named. We are convinced the specimens are biogenic and have placed them within Linnaean nomenclature as Horodyskia moniliformis Yochelson and Fedonkin. An apt description of the locally abundant fossils is "string of beads". On each string, beads are of nearly uniform size and spacing; proportionally, bead size and spacing remain almost constant, regardless of string length or size of individual beads. They may not be related to any other known fossil, and their position within highest levels of the taxonomic hierarchy is enigmatic. We judge they were multicellular, tissue-grade, colonial eucaryotes. Similar strings have been reported from Western Australia, but nowhere else. The general geologic setting in Montana, details of sedimentation, and taphonomy suggest the organisms were benthonic, growing upward about 1 cm through episodically deposited eolian dust. During life, specimens were stiff and relatively strong, but show no evidence of a mineralized skeleton. They lived in poorly oxygenated water with the body progressively subjected to anaerobic conditions. Their energy source is obscure; their mode of growth and several features of interpreted environment lead us to speculate that Horodyskia likely lived primarily by ingesting chemosynthetic bacteria rather than by photosynthesis. This notion should be tested by searching red, fine-grained, subaqueous arenites of approximately the same age throughout the world for additional occurrences.

The study includes an extended outgroup analysis of Cambrian molluscs. The resulting estimates of gastropod phylogeny differ not only from traditional ideas about early gastropod relationships, but also from most alternative notions. Outgroup analyses suggest that gastropods had ancestors among the Tergomya (= Monoplacophora of many workers) of the Middle or Late Cambrian. Putative gastropods from older strata (e.g., the Pelagiellida and early Onychochilidae) apparently are not closely related to gastropods. The hypothesized ancestor of gastropods possessed dextral-coiling, septation, a deep sinus, and a peripheral band. An anal slit is commonly described as a synapomorphy of gastropods that many clades subsequently lost; however, this study suggests that the slit is a rare, highly derived, and polyphyletic character among early Paleozoic species, and that the ancestors of most "advanced" clades (e.g., the Apogastropoda) never had slits. This study suggests that two major subclades evolved by the earliest Ordovician. The diagnoses and definitions of these two subclades best correspond to the traditional diagnoses and definitions of the Euomphalina and Murchisoniina. The Pleurotomarioidea is not a paraphyletic ancestral taxon as typically suggested, but instead it is a polyphyletic assemblage derived multiple times from "euomphalinae" and "murchisoniinae" species. The Bellerophontina is at least diphyletic, as the taxon includes both the ancestors of "archaeogastropods" and a clade of planispiral species that is secondarily derived from "archaeogastropods". Macluritoids sensu stricto represent a restricted subclade of the "euomphalinae"; other supposed macluritoids evolved among different euomphalinae subclades or are not gastropods. Early Paleozoic species previously classified as caenogastropods (i.e., the Loxonematoidea and Subulitoidea) represent separate murchisoniinae subclades, with some putative members of the Subulitoidea derived within the Loxonematoidea. Early Paleozoic species assigned to the Trochoidea also represent several subclades, with most of those clades having evolved from the "euomphalinae". An extensive taxonomic revision is presented, which removes all early Paleozoic taxa from the Pleurotomariina and broadly expands the definitions of the Euomphalina and Murchisoniina.

Several of the new Apternodus specimens are also associated with postcrania. We recognize seven species of Apternodus, three of which are new, formally propose the combination Oligoryctes altitalonidus, and recognize two other genera of small, North American, anatomically zalambdodont placentals, Parapternodus and Koniaryctes. We regard two other taxa previously associated with North American fossil zalambdodonts, one Bridgerian and the other Tiffanian, as valid but do not name them in this paper. In addition, we argue that dental zalambdodonty entails a primary occlusal relationship between the paracone and the ectoflexid, and the reduction or absence of the metacone and talonid basin. A phylogenetic analysis of cranial, dental, and postcranial characters of 30 fossil and Recent taxa leads us to conclude that (1) the Apternodontidae as defined in previous literature is not monophyletic and should be restricted to seven species of Apternodus, (2) the genus Oligoryctes contains at least two species and has a considerably longer geologic record than Apternodus, (3) neither Micropternodus nor currently known Paleocene taxa are closely related to Apternodus or Oligoryctes, and (4) a case can be made for a close relationship among modern soricids, Parapternodus, Koniaryctes, Oligoryctes, and Apternodus to the exclusion of other insectivoran-grade taxa. With the use of ordered, multistate character transformations, Solenodon comprises the sister taxon to a soricid-fossil zalambdodont clade.

Of special interest is fossil plant damage attributable to leaf mining and galling taxa that is very similar or identical to modern damage on the same host genera, indicating the geologically long-term persistence of some associations. Other types of middle Eocene, insect-mediated damage appear generalized and are not assignable to known types of modern associations, owing in part to imperfect taxonomic resolution of plant host, insect herbivore, or more likely, extinction. This preliminary report records the taxonomically diverse and morphologically detailed wealth of preserved foliar material in a Lagerstatte, which is important for addressing the macroevolutionary tempo of plant-insect associations. This relevance includes the prevalence of long-term associations, extinction of plant host and interacting insect herbivores, and the occurrence of host-switching at Cenozoic time scales for taxa presently confined to eastern Asia and North America.

The method is based on seeking relationships between geologic structures and geodetic observations of regional tectonic strain. The working hypothesis is that geothermal plumbing systems might in some regions be controlled by fault planes acting as conduits that are continuously being stressed apart by tectonic activity. Specifically, this type of model would predict that geothermal activity would be spatially correlated with areas of high inter-seismic strain accumulation, especially when faults are favorably oriented with respect to the strain-rate tensor field. We tested these predictions in the Great Basin using tectonic velocity gradients derived from a network of Global Positioning System (GPS) sites, producing a regional strain-rate map with precision approaching a few parts per billion per year in some regions. Our initial conclusions are that regions of high inter-seismic strain accumulation correlate significantly with high geothermal well temperatures and the locations of geothermal power-producing sites. The next step is to test the prediction that fault orientation is also important, and that this information can be used to enhance the predictive capability of regional geodetic strain to target potential geothermal resources.

This progression of geology from being a strictly Earth-centred science to one that is planetary-wide has provided us with a wealth of information on the evolutionary histories of other bodies and has supplied valuable new insights on the Earth itself. We have learned, for example, that the Earth-Moon system most likely formed as a result of a collision in space between the protoearth and a large impactor, and that the Moon subsequently accreted largely from debris of Earth's mantle. The airless, waterless Moon still preserves a record of the impact events that have scarred its surface from the time its crust first formed. The much larger, volcanic Earth underwent a similar bombardment but most of the evidence was lost during the earliest 550 million years or so that elapsed before its first surviving systems of crustal rocks formed. Therefore, we decipher Earth's earliest history by investigating the record on the Moon. Lunar samples collected by the Apollo astronauts of the USA and the robotic Luna missions of the former USSR linked the Earth and Moon by their oxygen isotopic compositions and enabled us to construct a timescale of lunar events keyed to dated samples. They also permitted us to identify certain meteorites as fragments of the lunar crust that were projected to the Earth by impacts on the Moon. Similarly, analyses of the Martian surface soils and atmosphere by the Viking and Pathfinder missions led to the identification of meteorite fragments ejected by hypervelocity impacts on Mars. Images of Mars displayed landforms wrought in the past by voluminous floodwaters, similar to those of the long-controversial Channeled Scablands of Washington State, USA. The record on Mars confirmed catastrophic flooding as a significant geomorphic process on at least one other planet. The first views of the Earth photographed by the crew of Apollo 8 gave us the concept of "Spaceship Earth" and heightened international concern for protection of the global environment.

These two fossil assemblages were deposited in small sinkholes or sinkhole/cave systems that developed in the marine Pleistocene Miami Limestone when sea level was considerably lower than present, probably during the latter part of the Wisconsinan glacial interval between 20 and 11 Ka. The mammalian fauna from Cutler Hammock consists of 47 species, including 16 members of the extinct Pleistocene megafauna. The most common larger mammals from Cutler Hammock are Mylohyus nasutus, Equus sp., Bison antiquus, and Canis dirus. Small vertebrates, including toads, snakes, birds, bats, rodents, and rabbits, are abundant in this site. The presence of a diverse fauna of large carnivores, particularly the dire wolf, Canis dirus, and the fragmentary condition of most ungulate long bones, some of which show clear evidence of gnawing, suggest that Cutler Hammock functioned, in part, as a carnivore den. Monkey Jungle Hammock has 41 species of mammals, nine of which are of extinct megafauna. Small mammals, including 12 species of rodents and eight species of bats, dominate the Monkey Jungle fauna. Mammals from Cutler and/or Monkey Jungle that are unknown in Florida before the late Rancholabrean include Panthera atrox, Puma concolor, Ursus americanus, Sciurus niger, Pitymys pinetorum, Sigmodon hispidus, and Bison antiquus. The West Palm Beach site, located about 100 km north of Cutler and Monkey Jungle in Palm Beach County, has 11 species of extinct megafauna among its 17 species of mammals. The most common mammals in this fauna are the proboscideans Mammut americanum and Mammuthus columbi. Mammals of South American origin, including species of ground sloths, armadillos, glyptodonts, vampire bats, and capybaras, are present in many Florida Pleistocene faunas. These South American Species occur in Florida faunas along with species of North American origin that either are restricted to the Neotropics at the present time (e.g., jaguar, Panthera onca) or are closely related to living Neotropical species (e.g., extinct Florida cave bear, Tremarctos floridanus, and extinct tapir, Tapirus veroensis). The evolutionary history and biogeography of Florida's Pleistocene mammals with Neotropical affinities are thoroughly analyzed.

These wetland habitats generally support aquatic taxa that are widespread throughout North America. Recent work has complemented the studies of endemic fishes by Carl Hubbs and Robert Miller and has served to identify a diverse fauna of insects and mollusks endemic to the Great Basin. The presence of this fauna in comparatively small wetlands shows that habitat size is not a good indicator of the importance of these wetlands to unique biological communities. Historical and current records show that anthropogenic activities during the last 120 years have modified the structure of Great Basin aquatic communities by altering habitats and by the translocation of species. Fifty nonnative fish taxa and several invertebrate taxa have been introduced into the region by the public and/or by fishery management agencies. Twenty-four fish taxa endemic to the Great Basin also have been translocated into habitats both within and outside of their native range. Most of these translocations were undertaken to create refuge populations and, thus, to reduce the possibility of extinction. Within the Great Basin, introductions of nonnative species and habitat modification have caused the extinction of 16 endemic species, subspecies, or other distinctive populations (12 fishes, three mollusks, and one aquatic insect) since the late 1800s. Declines in abundance or distribution were attributable (in order of decreasing importance) to water flow diversions, competitive or predatory interactions with nonnative species, livestock grazing, introductions for sport fisheries management, groundwater pumping, species hybridization, timber harvest, pollution, recreation, and habitat urbanization. Most affected taxa were influenced by more than one of these factors. The temporal pattern of decline in endemic taxa was examined by determining the calendar decades of first population loss, of major decline (loss of one-half of either a taxon's distribution or abundance), and of extinction for 199 endemic taxa (102 fishes, 85 mollusks, nine aquatic insects, two amphibians, and one fairy shrimp). Population loss has affected approximately 50 percent of taxa for which information was available (135 distinct taxa: 99 fishes, 24 mollusks, and all taxa in the three other aquatic animal groups), and 58 percent of these taxa have suffered major declines. Differences among rates of population loss, major decline, and extinction were not significant (ANCOVA, p > 0.05). Declines and extinctions were first recorded in the late 1800s. Rates peaked first after World War I and again in the 1970s after a long increase that began after World War II. Status was comparatively static during both World Wars. This pattern indicates that declines can be attributed to regional economic conditions and increased immigration. Declines slowed in the 1980s and 1990s because most taxa had previously declined, not because threats had diminished. Declines during the last 120 years have been greatest in the most narrowly distributed and vulnerable populations. All extinct taxa and most taxa suffering major declines (68 percent) had fewer than five populations. If past trends continue into the future, additional extinctions will occur (primarily in narrowly distributed taxa), and extinctions also may begin to affect widespread taxa. These changes will accompany environmental change that characterizes consumption patterns of increasing human populations. Avoiding future changes in Great Basin biogeography that result from declines in taxon status will require new, innovative programs that protect wetland habitats from environmental degradation and the deleterious effects of nonnative species while allowing appropriate human uses of wetland resources.

These ideas persist, and, indeed, provide the theoretical basis for many modern studies of migrant evolution. However, recent studies have established that migrant ecology is more complex, with many migrants using stable resources and demonstrating site fidelity to a broad range of Tropical habitats, both within and between wintering seasons. Furthermore, intra-Tropical movements are now known to occur in a number of Tropical resident species as well as migrants, and appear related to resource and habitat seasonality. These findings, plus extensive taxonomic evidence, indicate that most long-distance migrants to temperate and boreal breeding sites are derived from Tropical-breeding resident birds, emphasising the critical importance of taking into account selective factors and evolution occurring during the non-breeding portion of the life cycle. The three principal Holarctic migration systems are similar in these and many other aspects, but differ in that, while roughly one third of the Nearctic/Neotropical and eastern Palearctic/Asian Tropical migrants winter in forest, almost none of European/Afrotropical migrants do so. We propose that habitats connecting Holarctic and Tropical regions serve as a filter for potential migrants to the Holarctic, and that absence of forest from northern Africa has limited exploitation of European forests by Afrotropical species.

Egg-laying extended from mid-March to the first week of December, showing two well-defined peaks in April and August-September. The extended breeding period of these birds was the result of individuals having a second clutch. About half of the females (n =189) had two clutches per year, most of which were double broods (73%). The date of completion and outcome of reproduction, or whether a change of mates occurred from the previous year, did not affect timing of egg laying. The majority of first clutches (62%) were laid in April each year. Two-clutch breeders that started laying eggs early in April had a higher breeding success than those starting in late April, and double brooders had greater success than single brooders. Two-clutch breeders started to lay eggs earlier than single-clutch breeders. Taking into account that a penguin breeding cycle (from egg laying to fledging) lasts similar to 4 months, laying eggs early in April increases the chance of rearing two successful broods per year. During three consecutive years, females tended to have two clutches instead of only one clutch and an average breeding success of 4.54 fledglings over 3 years. Having as many clutches as possible when conditions are favorable appears to be a strategy used by Humboldt Penguins to maximize their lifetime reproductive success within a productive but unpredictable environment.Original Abstract: Entre 1993 y 1997 analizamos los patrones de puesta de huevos y frecuencia reproductiva de Spheniscus humboldti (Pingueino de Humboldt) en Punta San Juan, Peru. La puesta de huevos se extendio desde mediados de marzo hasta la primera semana de diciembre, mostrando dos picos bien definidos en abril y agosto-septiembre. El largo periodo de nidificacion de estas aves se dio como resultado de la puesta de una segunda nidada por parte de algunos individuos. Aproximadamente la mitad de las hembras (n = 189) pusieron dos nidadas por ano, la mayoria de las cuales presentaron dos crias (73%). La fecha de finalizacion y el resultado reproductivo, o si ocurrio un cambio de pareja desde el ano anterior, no afecto la coordinacion en la puesta de huevos. La mayoria de las primeras nidadas (62%) fueron puestas en abril de cada ano. Las parejas con dos nidadas que comenzaron a poner sus huevos al comienzo de abril tuvieron un exito reproductivo mayor que las que comenzaron a fines de abril. Las parejas que criaron dos pichones fueron mas exitosas que las que criaron un solo pichon. Las parejas con dos pichones comenzaron a poner sus huevos mas temprano que las parejas con una sola cria. Considerando que el ciclo de cria de un pingueino (desde la puesta del huevo hasta dejar el nido) dura similar to 4 meses, poner los huevos a principios de abril incrementa las chances de criar exitosamente dos nidadas por ano. Durante tres anos consecutivos, las hembras tendieron a presentar dos nidadas en lugar de una sola y un exito reproductivo promedio de 4.54 volantones en tres anos. La estrategia de S. humboldti parece basarse en tener la mayor cantidad posible de nidadas cuando las condiciones son favorables para asi maximizar el exito reproductivo total en un ambiente productivo pero impredecible.

After burning a stand of scrub-oak vegetation, re-growing plants were exposed to either current ambient (379 mu L L super(-1) CO sub(2) ) or elevated (704 mu L L super(-1) CO sub(2) ) C sub(a) in 16 open-top chambers over a four-year period, and measurements of stem diameter were carried out annually on all oak shoots within each chamber. Elevated C sub(a) significantly increased aboveground biomass, expressed either per unit ground area or per shoot; elevated C sub(a) had no effect on shoot density. The relative effect of elevated C sub(a) on aboveground biomass increased each year of the study from 44% (May 96-Jan 97), to 55% (Jan 97-Jan 98), 66% (Jan 98-Jan 99), and 75% (Jan 99-Jan 00). The effect of elevated C sub(a) was species specific: elevated C sub(a) significantly increased aboveground biomass of the dominant species, Q. myrtifolia , and tended to increase aboveground biomass of Q. chapmanii , but had no effect on aboveground biomass of the subdominant, Q. geminata . These results show that rising atmospheric CO sub(2) has the potential to stimulate aboveground biomass production in ecosystems dominated by woody species, and that species-specific growth responses could, in the long term, alter the composition of the scrub-oak community.

The purpose of this research was to assess how sonic booms affect these seals. The intensity of the booms was measured and three types of data (beach counts, frequency of behavior, and heart rate) were collected before and after booms during the breeding seasons of the two species. In addition to the data taken during breeding, beach counts were made before and after booms during the gray seal moult. The greatest range in overpressure within a single boom was 2.70 psf during gray seal breeding and 2.07 psf during harbor seal breeding. No significant differences were found in the behavior or beach counts of gray seals following sonic booms, regardless of the season. Beach counts and most behaviors of harbor seals also did not differ significantly following booms, however, harbor seals became more vigilant. The heart rates of four gray seal mothers and three pups showed no clear change as a result of booms, but six male harbor seals showed a nonsignificant tendency toward elevated heart rates during the 15-s interval of the boom. These results suggest sonic booms produced by the Concorde, in level flight at altitude and producing on average a sonic boom of 0.9 psf, do not substantially affect the breeding behavior of gray or harbor seals.

Three hypotheses receive strong support. Niche differences are evident from non-random spatial distributions along micro-topographic gradients and from a survivorship-growth tradeoff during regeneration. Host-specific pests reduce recruitment near reproductive adults (the Janzen-Connell effect), and, negative density dependence occurs over larger spatial scales among the more abundant species and may regulate their populations. A fourth hypothesis, that suppressed understory plants rarely come into competition with one another, has not been considered before and has profound implications for species coexistence. These hypotheses are mutually compatible. Infrequent competition among suppressed understory plants, niche differences, and Janzen-Connell effects may facilitate the coexistence of the many rare plant species found in tropical forests while negative density dependence regulates the few most successful and abundant species.

Although observation and theory have resulted in a conceptual framework for invasion ecology, the empirical data needed to rigorously test many key hypotheses and develop robust predictions lag far behind. This gap is especially conspicuous for marine systems, existing both in the quality and quantity of descriptive data. At the present time, most analyses that evaluate patterns of invasion or test specific hypotheses derive data from the existing literature, which is extremely uneven in space and time, This 'by-catch' approach to data collection can result in biases, creating apparent patterns that must be viewed with caution. Quantitative field surveys, which employ standardized and repeatable measures, can be used to remove such bias. We call for a concerted international effort to conduct quantitative surveys, designed explicitly to test a variety of hypotheses and to produce the high-quality empirical data that is now lacking. Without this information base, many fundamental questions in marine invasion ecology will remain unresolved, limiting advances for basic science as well as its ability to guide effective management and policy.

Close-interval sampling enabled chronological resolution at a century-scale or less. Modern ecologic studies of diatoms and ostracodes, as well as climatic and hydrologic processes affecting the Owens Lake basin, were used to track environmental changes. The middle Wisconsin to Holocene record indicates that climates wetter than those of modern times existed 80 percent of the time, but that changes between wet and dry climates occurred rapidly - within 300 years to a century or less in some instances. The ostracode record indicates that polar air masses permanently resided at the latitude of Owens Lake during parts of the full-glacial period, whereas the diatom record and heavy-mineral analyses imply that extensive alpine glaciers (on the scale of the full-glacial period) did not exist in the Owens Lake drainage before 22 thousand years ago (Ka) and that the effects of glaciation on sedimentation in this area ended by 13 Ka. During oxygen-isotope stage 3 ( similar to 50-25 Ka) at Owens Lake, summer-season freshwater planktonic diatoms correlate with geochemical evidence related to increased winter precipitation in marine cores at similar latitudes on the California margin. These data document southward shifts and increased strength of the Aleutian low-pressure system (Aleutian Low) in the northeast Pacific Ocean and its role in determining the hydrologic balance of western North America as well as its effect on the California Current. Such correlations indicate that the Owens Lake paleolimnological record responded to the major dynamics of climate variation in the northern hemisphere.

This byssal mat-forming species can become overwhelmingly dominant and have dramatic impacts within invaded ecosystems, but its invasion may meet "ecological resistance" from native predators. In Mission Bay, San Diego, California, three fish species and two shorebirds were found to prey upon the mussel. Experimental results suggest that predation can dramatically impact intertidal mussel populations and may account for observed seasonal declines in the species. Despite the creation of abyssal cocoon, which may afford the mussel some protection, several taxa worldwide have been found to be Musculista predators. In addition, in areas where the mussel is native, humans impact mussel populations by gathering it for animal feed or bait, or to remove it from commercial shellfisheries grounds.
