Although direct inheritance is seen in a large proportion of Cheyenne animate & inanimate plural, obviative, & possessive inflections, the regular loss of Proto-Algonquian word-final *-nki in Cheyenne has led to restructuring of the locative ending *-enki, which surfaces as -e/-a in Cheyenne. With a high tolerance for irregularity, Cheyenne retains much of the verb morphology of Proto-Algonquian, particularly in the conjunct orders, objective forms of the transitive & intransitive animate independent indicative, & participial endings; reshaping of affixes is found elsewhere, & Cheyenne has imperative & other independent modal formations of obscure origin. 29 References.

In contrast to the putative hexagonal cell, weak XRD maxima on precession films demonstrate that the parisite-(Ce) is monoclinic with a space group C2/c or Cc. The unit cell was refined as a = 12.305(2), b = 7.1053(5), c = 28.250(5) Aa, and beta = 98.257(14) degrees . The structure refinement confirmed the space group Cc. Like bastnasite and synchysite, parisite possesses a (001) layer structure, with layers of (Ca) and (CeF) separated by layers of carbonate groups. The [001] layer stacking sequence is ...

The parisite-(Ce) structure can be considered as two portions of the bastnasite structure connected by a (Ca) layer. The insertion of a (Ca) layer would create long [001] (super *) structure voids in the F columns if the bastnasite portions stacked hexagonally; therefore, the two bastnasite portions are offset along [110] by a/6(sin60 degrees ) (or [100] in hexagonal cells, by a/3) such that the oxygen atoms of the vertical edges of the carbonate groups occupy the voids. Polytypism results because a bastnasite portion can shift equally in two possible directions, + or -120 degrees from the previous offset vector. The parisite-(Ce) structure elucidated herein is the simplest and most common polytype possible, 2M. The polytype 6R, which was previously believed to be the most common, has not been found during our extensive study.

Its activity is divided into three stages of decreasing eruptive volume. During stage-1 activity, the main cone of San Juan and the adjacent Cerro Alto grew to a combined volume of approximately 60 km (super 3) through eruption of hornblende-bearing andesites, dacites, and rhyodacites. Stage 1 included explosive eruptions of hornblende-dacite and an andesite dated at 33,750 a (years ago) and 23,010 a. Stage-2 activity involved a major Plinian eruption 14,770 a that produced the hypersthene-hornblende-bearing, compositionally zoned, rhyodacitic-andesitic Tepic Pumice and led to formation of an oval-shaped caldera 4X1 km in diameter. Tepic, the capital city of Nayarit State, with a population of approximately 250,000, lies at the NE foot of Volcan San Juan. This location was buried under 2-9 m of rhyodacitic pumice-fall deposits from the Tepic Pumice eruption. Erosion has since removed virtually all exposures of Tepic Pumice >15 km from the caldera. The estimated volume of erupted tephra is 5.6 km (super 3) , equivalent to 1.2 km (super 3) of magma. Modeling of the eruption dynamics indicates that as the eruption evolved the column height increased from approximately 15 km to approximately 24 km and maximum mass discharge rate increased from approximately 3X10 (super 6) kg/s to approximately 6X10 (super 7) kg/s. During stage-3 activity, a hornblende-andesitic lava dome partially filled the caldera and sent block lava flows down the north slope of the cone; total erupted volume was approximately 0.55 km (super 3) . Compared to other composite volcanoes of the western Mexican Volcanic Belt, the products from San Juan have the highest Sr contents and the lowest Rb, Y, Yb, and Lu contents, resulting in high La/Yb and Sr/Y, with low Rb/Sr. These observations indicate a strong slab-melt component at San Juan, consistent with its proximity to the Middle America Trench where young, hot lithosphere is subducting. The San Juan andesites, dacites, and rhyodacites also have relatively high (super 87) Sr/ (super 86) Sr, (super 206) Pb/ (super 204) Pb, (super 207) Pb/ (super 204) Pb, and (super 208) Pb/ (super 204) Pb, and low epsilon (sub Nd) values compared to these other volcanoes, which appear to reflect significant crustal contamination of San Juan's magmas.

The watersheds have a clay aquiclude and were equipped with V-notch weirs and continuous volume-integrating water samplers. The beaver pond reduced annual discharge of water, total-N, total-P, dissolved silicate, TOC, and TSS by 8, 18, 21, 32, 28, and 27%, respectively. Most of the total-N reduction was due to increased retention of nitrate in the winter and spring and TON in the winter and summer. Most of the total-P reduction was the result of retention of both TPi and TOP in the winter and summer. Dissolved silicate retention peaked in the spring, while TOC and TSS retention peaked in the winter. Prior to the formation of the beaver pond, concentrations of TON, TPi, TOP, TOC, and TSS had highly significant correlations with stream discharge, especially in the winter, but subsequent to the pond there was little or no relationship between these concentrations and stream discharge. However, concentrations of nitrate in the spring and ammonium in the summer were highly correlated with stream discharge both before and after the formation of the beaver pond and regressions of discharge versus concentrations of these nutrients explained more of the variation in concentrations after the formation of the pond.

These cycles actually represent carbonate shedding from a shoal on the geanticline developed between the Delaware basin and the Marathon foreland basin. The Road Canyon was deposited in the foreland basin as (1) a skeletal wackestone deposited behind a shoal (geanticline), (2) a peloidal packstone deposited on the slope, and (3) a siltstone deposited in the basin. The cycles represent shoalward progradation of the basinal deposits. Rudstone was deposited in channels immediately behind the shoal. Back shoal facies are represented by bioturbated lime mudstone with common channels of conglomeratic wackestone.

One zone, Mesogondolella nankingensis, is divided into two subzones; the subzone boundary nearly coincides with the Roadian-Wordian stage boundary as perceived by Glenister et. al. (1992). The base of the Guadalupian is easily defined by the evolutionary transition from Mesogondolella idahoensis to M. nankingensis (Grant and Wardlaw, 1986; Lambert and Wardlaw, 1992; Lambert et al., this volume). The depositional setting of the majority of the rocks found in the Glass and Del Norte mountains is that of a foreland basin, with the clastic sediments derived from the Marathon Fold Belt and the carbonate and carbonate debris derived from a shoal formed on the geanticline between the foreland basin and the "deep" Delaware basin depositional complex. The taxonomy of the many serrated Mesogondolella species is clarified, and several species are synonomized. New species described are Sweetina crofti, Hindeodus wordensis, Iranognathus punctatus, and Sweetognathus bicarinum.

The internal stratigraphy within the Cutoff Formation is complex, and to date only informal schemes have been proposed. Three members are defined, which in ascending order are the Shumard Member, the El Centro Member, and the Williams Ranch Member. Type sections for these members are all located in the southern part of the western escarpment within the Guadalupe Mountains National Park. These members are proposed to reinforce the revisions in the stratigraphic framework for these beds since the pioneering work of King (1942, 1948) and Newell et al. (1953). These members can be traced throughout the western escarpment region and are stratigraphically distinct units separated by unconformities or lithologic changes. The proposed members probably represent the extent to which previous faunal collections can be located. These collections are important because these strata are a candidate for an international boundary stratotype (Glenister et al., 1991; Glenister, 1991).

The Cutoff Formation is composed of a basinal facies dominated by carbonate and siliciclastic lutites that were deposited over an eroded Leonardian (Victorio Peak-Bone Spring) bank margin. These lithologies resulted from an abrupt eustatic deepening (40-50 m), which brought anoxic (dysaerobic) conditions onto the outer shelf and caused the shallow-water shelf to retreat 19-23 km to the northwest. Coarse rudstone and megabreccia deposits consisting of allochthonous clasts occur in slope channels. Prominent submarine unconformities at the base, as well as within and at the top of the Cutoff strata, extend from the shelf to the basin. Pre-Cutoff erosion steepened the underlying bank margin to a 5 degrees -20 degrees slope. Post-Cutoff erosion locally removed Cutoff strata, resulting in a discontinuous outcrop along the slope. The recognition of five intra-Cutoff correlation units, based upon lutite composition, provides a detailed stratigraphic framework that helps resolve shelf-to-basin correlations. A complete shelf-to-basin profile, exposed at a high angle to the shelf margin, provides unambiguous evidence that the unconformities are regional surfaces, and that the coarse deposits are down-slope debris. The Road Canyon Formation consists largely of organic-rich lutites bearing spiculites and radiolarians. Like the Cutoff Formation, it contains allochthonous megabreccias, conglomerates, and sand sheets. Megabreccias and conglomerates occur as channelized deposits, whereas coarse carbonate sands occur in sheet geometries. Lamination textures in the lutites indicate that the allochthonous material was deposited in an anoxic (dysaerobic to anaerobic) slope or deep shelf setting. The recognition of a succession of seven depositional units allows correlation across the central Glass Mountains. No regionally extensive unconformity surfaces were noted. The comparison of the two formations indicates a similar depositional environment: an anoxic slope-to-basin setting with both fine-grained autochthonous sediments and coarse-grained allochthonous debris. The Road Canyon outcrop belt, however, nearly parallels depositional strike, making its interpretation more difficult (and comparison to Cutoff strata more useful). The recognition of the depositional environments, detailed internal successions, and relative stratigraphic completeness provides the necessary framework for better interpreting the biostratigraphic data relevant to defining the Leonardian-Guadalupian boundary as discussed in an accompanying contribution (Lambert, Lehrmann, and Harris, this volume).

Glenister (1991) and Glenister et al. (1992) have outlined both the criteria required and the desirable attributes of the Guadalupian Series (Girty, 1902, 1908) for fulfilling the necessary requirements. The present paper seeks to elucidate the importance of fusulinaceans in helping to fulfill these requirements. Fusulinaceans occur, often in abundance, throughout the Carboniferous and Permian, and species of this large group of microfossils form an ideal evolutionary continuum. Along with conodonts and ammonoids, in particular, fusulinaceans offer an excellent means by which the well-established sedimentological history of the West Texas Permian can be zoned and applied on a worldwide basis.

Shumard's (1860) basal "black limestone" at the bottom of Guadalupe Pass was explicitly included as the lowermost unit when Girty (1902) proposed the Guadalupian Series. Adams et al. (1939) considered the black limestone to represent the Bone Spring Limestone, and its fossils to be Leonardian. Accurate correlation demonstrates that the black limestone is the upper unit of the basinal Cutoff Formation. The reassignment of previously described fossil localities to their correct stratigraphic position clarifies temporal faunal relationships, and the Road Canyon and Cutoff formations are proven to be largely correlative. Roadian ammonoid, conodont, and fusulinid faunas are distinctive, and the biostratigraphy records when each of these important groups is first represented by characteristic Guadalupian forms. Predicated on both the improved database and consideration of priority and stability, a return to Girty's original Guadalupian Series concept is recommended. This supports retaining the Roadian as the basal stage of the Guadalupian Series. It is also proposed that the mutual basal boundary of the Guadalupian and Roadian be established within the morphological continuum through which the conodont species Mesogondolella idahoensis evolved into M. nankingensis. Thus defined, the Guadalupian Series is a leading candidate as the international standard for establishing a formal Middle Permian Series.

Deposition was alternately influenced by coarse clastic input from the orogen and carbonate input from the shoal, which interrupted shallow basinal siltstone deposition. Relatively deeper-water deposition is characterized by carbonate input from the shoal, and relatively shallow-water deposition is characterized by sandstone input from the orogen.

One species of Rauserella Dunbar, 1944, three species of Reichelina Erk, 1942, and six species of Parafusulina Dunbar and Skinner, 1931, are described as new. The Guadalupian fusulinid-bearing sequence of strata in the Glass Mountains and Del Norte Mountains area contains abundant fusulinid faunas, with especially diverse fusulinid faunas present in the Road Canyon Formation and the Altuda Formation, primarily in sediments of shelf margin and slope-to-basin depositional environments. The Mesogondolella nankingensis (conodont) first appearance datum lies between the Parafusulina boesei first appearance datum and the Parafusulina rothi first appearance datum, within the Road Canyon Formation. Nine fusulinid zones are recognized. Of these zones, the Parafusulina durhami Zone is placed in the Leonardian Stage, the Parafusulina boesei Zone spans the boundary of the Leonardian and Guadalupian (as defined by the Mesogondolella nankingensis first appearance datum), and the Parafusulina rothi Zone, Parafusulina trumpyi Zone (Roadian Stage), Parafusulina sellardsi Zone, Parafusulina antimonioensis Zone (Wordian Stage), Polydiexodina shumardi Zone, Reichelina lamarensis Zone, and Lantschichites splendens Zone (Capitanian Stage) are placed in the Guadalupian Series.

The youngest of these is the archeological record (e.g., <10 k.y. B.P.), when organic matter from living organisms undergoes the preliminary stages of fossilization (certain classes of biomolecule are selectively preserved while others undergo rapid degradation). The second time slice is the Tertiary. Well-preserved fossils of this age retain diagenetically modified biomarkers and biopolymers for which a product-precursor relationship with the original biological materials can still be identified. The final time slice is the Carboniferous. Organic material of this age has generally undergone such extensive diagenetic degradation that only the most resistant biopolymers remain and these have undergone substantial modification. Trends through time in the taphonomy and utility of ancient biomolecules in terrigenous fossils affect their potential for studies that involve chemosystematic and environmental data.

Owing in part to the advent and rapid expansion of computer technologies, the number of fossil plant form-function models has burgeoned in the last two decades and encompasses every level of biological organization ranging from molecular self-assembly to ecological and evolutionary dynamics. This recent and expansive interest in modeling fossil plant form-function relationships is discussed in the context of the general philosophy of modeling past biological systems and how the reliability of models can be examined (i.e., direct experimental manipulation or observation of the system being modeled). This philosophy is illustrated and methods of validating models are critiqued in terms of four models drawn from the author's work (the quantification of wind-induced stem bending stresses, wind pollination efficiency of early Paleozoic ovulate reproductive structures, population dynamics and species extinction in monotypic and "mixed" communities, and the adaptive radiation of early vascular land plants). The assumptions and logical (mathematical) consequences (predictions) of each model are broadly outlined, and, in each case, the model is shown to be overly simplistic despite its ability to predict the general or particular behavior or operation of the system modeled. Nonetheless, these four models, which illustrate some of pros and cons of modeling fossil form-function relationships, are argued to be pedagogically useful because, like all models, they expose the internal logical consistency of our basic assumptions about how organic form and function interrelate.

Late Quaternary records indicate the modes and mechanisms of environmental variation and biotic responses at timescales of 10 (super 1) -10 (super 4) years. Climatic changes of the late Quaternary have occurred continuously across a wide range of temporal scales, with the magnitude of change generally increasing with time span. Responses of terrestrial plant populations have ranged from tolerance in situ to moderate shifts in habitat to migration and/or extinction, depending on magnitudes and rates of environmental change. Species assemblages have been disaggregated and recombined, forming a changing array of vegetation patterns on the landscape. These patterns of change are characteristic of terrestrial plants and animals but may not be representative of all other life-forms or habitats. Complexity of response, particularly extent of species recombination, depends in part on the nature of the underlying environmental gradients and how they change through time. Environmental gradients in certain habitats may change in relatively simple fashion, allowing long-term persistence of species associations and spatial patterns. Consideration of late Quaternary climatic changes indicates that both the rate and magnitude of climatic changes anticipated for the coming century are unprecedented, presenting unique challenges to the biota of the planet.

These include assessing sample quality relevant to ecologic, biogeographic, and evolutionary questions, diagnosing the roles of various taphonomic agents, processes and circumstances in generating the sedimentary and fossil records, and reconstructing the dynamics of organic recycling over time as a part of Earth history. Major advances over the past 15 years have occurred in understanding (1) the controls on preservation, especially the ecology and biogeochemistry of soft-tissue preservation, and the dominance of biological versus physical agents in the destruction of remains from all major taxonomic groups (plants, invertebrates, vertebrates); (2) scale of spatial and temporal resolution, particularly the relatively minor role of out-of-habitat transport contrasted with the major effects of time-averaging; (3) quantitative compositional fidelity; that is, the degree to which different types of assemblages reflect the species composition and abundance of source faunas and floras; and (4) large-scale variations through time in preservational regimes (megabiases), caused by the evolution of new bodyplans and behavioral capabilities, and by broad-scale changes in climate, tectonics, and geochemistry of Earth surface systems. Paleobiological questions regarding major trends in biodiversity, major extinctions and recoveries, timing of cladogenesis and rates of evolution, and the role of environmental forcing in evolution all entail issues appropriate for taphonomic analysis, and a wide range of strategies are being developed to minimize the impact of sample incompleteness and bias. These include taphonomically robust metrics of paleontologic patterns, gap analysis, equalizing samples via rarefaction, inferences about preservation probability, isotaphonomic comparisons, taphonomic control taxa, and modeling of artificial fossil assemblages based on modern analogues. All of this work is yielding a more quantitative assessment of both the positive and negative aspects of paleobiological samples. Comparisons and syntheses of patterns across major groups and over a wider range of temporal and spatial scales present a challenging and exciting agenda for taphonomy in the coming decades.

Particular attention is focused on the independent estimation of origination and extinction rates. Modeling supports intuitive and empirical arguments that single-interval taxa, being especially sensitive to variation in preservation and interval length, produce many undesirable distortions of the fossil record. It may generally be preferable to base diversity and rate measures on estimated numbers of taxa extant at single points in time rather than to adjust conventional interval-based measures by discarding single-interval taxa. A combination of modeling and empirical analysis of fossil genera supports two major trends in marine animal evolution. (1) The Phanerozoic decline in taxonomic rates is unlikely to be an artifact of secular improvement in the quality of the fossil record, a point that has been argued before on different grounds. (2) The post-Paleozoic rise in diversity may be exaggerated by the essentially complete knowledge of the living fauna, but this bias is not the principal cause of the pattern. The pattern may partly reflect a secular increase in preservation nevertheless. Apparent temporal variation in taxonomic rates can be produced artificially by variation in preservation rate. Some empirical arguments suggest, however, that much of the short-term variation in taxonomic rates observed in the fossil record is real. (1) For marine animals as a whole, the quality of the fossil record of a higher taxon is not a good predictor of its apparent variability in taxonomic rates. (2) For a sample data set covering a cross-section of higher taxa in the Ordovician, most of the apparent variation in origination and extinction rates is not statistically attributable to independently measured variation in preservation rates. (3) Previous work has shown that standardized sampling to remove effects of variable preservation and sampling yields abundant temporal variation in estimated taxonomic rates. While modeling suggests which rate measures are likely to be most accurate in principle, the question of how best to capture true variation in taxonomic rates remains open.

Each data set spans the late Paleocene through Pleistocene and has temporal resolution of 1.0 m.y.; the mammal data are restricted to western North America. We use the isotope data to compute five separate time series: oxygen isotope ratios at the midpoint of each 1.0-m.y. bin; changes in these ratios across bins; absolute values of these changes (= isotopic volatility); standard deviations of multiple isotope measurements within each bin; and standard deviations that have been detrended and corrected for serial correlation. For the mammals, we compute 12 different variables: standing diversity at the start of each bin; per-lineage origination and extinction rates; total turnover; net diversification; the absolute value of net diversification (= diversification volatility); change in proportional representation of major orders, as measured by a simple index and by a G-statistic; and the mean, standard deviation, skewness, and kurtosis of body mass. Simple and liberal statistical analyses fail to show any consistent relationship between any two isotope and mammalian time series, other than some unavoidable correlations between a few untransformed, highly autocorrelated time series like the raw isotope and mean body mass curves. Standard methods of detrending and differencing remove these correlations. Some of the major climate shifts indicated by oxygen isotope records do correspond to major ecological and evolutionary transitions in the mammalian biota, but the nature of these correspondences is unpredictable, and several other such transitions occur at times of relatively little global climate change. We conclude that given currently available climate records, we cannot show that the impact of climate change on the broad patterns of mammalian evolution involves linear forcings; instead, we see only the relatively unpredictable effects of a few major events. Over the scale of the whole Cenozoic, intrinsic, biotic factors like logistic diversity dynamics and within-lineage evolutionary trends seem to be far more important.

To this end, sequence stratigraphy is an important tool for paleobiologists because it predicts the distribution of unconformities, facies changes, and changes in sedimentation rate, all factors known from numerous previous studies to affect the quality of the fossil record. Computer simulations now make it possible not only to model sequence architecture within sedimentary basins, but also to model the occurrence of fossils within those basins. These models generate predictions regarding the stratigraphic distribution of first and last occurrences, changes in species abundance, changes in species morphology, and the distribution of gaps in fossil ranges. Although confirmation of some of these predictions has been found in field studies, the extent to which these predictions describe the fossil record in general is still unknown. If the predicted patterns of fossil occurrences are found to be widespread, it will suggest that a relatively simple model of fossil occurrences in outcrops could become a new tool for solving a wide array of paleobiologic and biostratigraphic problems. With such models, paleobiologists and biostratigraphers will be able to use model data to test the accuracy of newly developed methods of analysis.

AN - 52148216; 2002-013967 AB - Issues of directionality in the history of life can be framed in terms of six major evolutionary steps, or megatrajectories (cf. Maynard Smith and Szathmary 1995): (1) evolution from the origin of life to the last common ancestor of extant organisms, (2) the metabolic diversification of bacteria and archaea, (3) eukaryotic cells, (4) multicellularity, (5) the invasion of the land and (6) technological intelligence. Within each megatrajectory, overall diversification conforms to a pattern of increasing variance bounded by a right wall as well as one on the left. However, the expanding envelope of forms and physiologies also reflects-at least in part-directional evolution within clades. Each megatrajectory has introduced fundamentally new evolutionary entities that garner resources in new ways, resulting in an unambiguously directional pattern of increasing ecological complexity marked by expanding ecospace utilization. The sequential addition of megatrajectories adheres to logical rules of ecosystem function, providing a blueprint for evolution that may have been followed to varying degrees wherever life has arisen.

Despite recently expressed doubts, conceptual and methodological developments over the past 25 years indicate that robust and testable claims about function can be produced. Functional statements can be made in at least three different hierarchical contexts, corresponding to the degree of structural information available, the position in the phylogenetic hierarchy, and the degree of anatomical specificity. The paradigm approach, which dominated thinking about function in the 1960s and 1970s, has been supplanted with a methodology based on biomechanics. Paleobiomechanics does not assume optimality in organismal design, but determines whether structures were capable of carrying out a given function. The paradigm approach can best be viewed as a way of generating, rather than testing, functional hypotheses. Hypotheses about function can also be developed and supported by well-corroborated phylogenetic arguments. Additional functional evidence can be derived from studies of trace fossils and of taphonomy. New computer techniques, including "Artificial Life" studies, have the potential for producing far more detailed ideas about function and mode of life than have been previously possible. Functional analysis remains the basis for studies of the history of adaptation. It is also an essential component of many paleoecological and paleoenvironmental studies.

Although the macroevolutionary exploration of developmental genetics has just begun, considerable progress has bee made in understanding the origin of evolutionary novelty in terms of the potential for coordinated morphological change and the potential for imposing uneven probabilities on different evolutionary directions. Global or whole-organism heterochrony, local heterochrony (affecting single structures, regions, or organ systems) and heterotopies (changes in the location of developmental events), and epigenetic mechanisms (which help to integrate the developing parts of an organism into a functional whole) together contribute to profound nonlinearities between genetic and morphologic change, by permitting the generation and accommodation of evolutionary novelties without pervasive, coordinated genetic changes; the limits of these developmental processes are poorly understood, however. The discordance across hierarchical levels in the production of evolutionary novelties through time, and among latitudes and environments, is an intriguing paleontological pattern whose explanation is controversial, in part because separating effects of genetics and ecology has proven difficult. At finer scales, species in the fossil record tend to be static over geologic time, although this stasis-to which there are gradualistic exceptions-generally appears to be underlain by extensive, nondirectional change rather than absolute invariance. Only a few studies have met the necessary protocols for the analysis of evolutionary tempo and mode at the species level, and so the distribution of evolutionary patterns among clades, environments, and modes of life remains poorly understood. Sorting among taxa is widely accepted in principle as an evolutionary mechanism, but detailed analyses are scarce; if geographic range or population density can be treated as traits above the organismic level, then the paleontological and macroecological literature abounds in potential raw material for such analyses. Even if taxon sorting operates on traits that are not emergent at the species level, the differential speciation and extinction rates can shape large-scale evolutionary patterns in ways that are not simple extrapolations from short-term evolution at the organismal level. Changes in origination and extinction rates can evidently be mediated by interactions with other clades, although such interactions need to be studied in a geographically explicit fashion before the relative roles of biotic and physical factors can be assessed. Incumbency effects are important at many scales, with the most dramatic manifestation being the postextinction diversifications that follow the removal of incumbents. However, mass extinctions are evolutionarily important not only for the removal of dominant taxa, which can occur according to rules that differ from those operating during times of lower extinction intensity, but also for the dramatic diversifications that follow upon the removal or depletion of incumbents. Mass extinctions do not entirely reset the evolutionary clock, so survivors can exhibit unbroken evolutionary continuity, trends that suffer setbacks but then resume, or failure to participate in the recovery.

Understanding the mechanisms behind the establishment of new designs involves integrating scientific disciplines that use different data and, often, different means of testing hypotheses. Discoveries from both paleontology and developmental genetics have shed new light on the origin of morphological novelties. The genes that play a major role in establishing the primary axes of the body and appendages, and that regulate the expression of the genes that are responsible for initiating the making of structures such as eyes, or hearts, are highly conserved between phyla. This implies that it is not new genes, per se, that underlie much of morphological innovation, but that it is changes in when and where these and other genes are expressed that constitute the underlying mechanistic basis of morphological innovation. Gene duplication is also a source of developmental innovation, but it is possible that it is not the increased number of genes (and their subsequent divergence) that is most important in the evolution of new morphologies; rather it may be the duplication of their regulatory regions that provides the raw material for morphological novelty. Bridging the gap between microevolution and macroevolution will involve understanding the mechanisms behind the production of morphological variation. It appears that relatively few genetic changes may be responsible for most of the observed phenotypic differences between species, at least in some instances. In addition, advances in our understanding of the mechanistic basis of animal development offer the opportunity to deepen our insight into the nature of the Cambrian explosion. With the advent of whole-genome sequencing, we should see accelerated progress in understanding the relationship between the genotype, phenotype, and environment: post-genomics paleontology promises to be most exciting.

Despite the enormous progress in the measurement and interpretation of Phanerozoic diversity over the past quarter century, much of which has been reported in Paleobiology, these studies have collectively generated at least as many new questions as they have answered-arguably the mark of an area of inquiry that continues to be vital. In this essay, I discuss several outstanding issues in the investigation of Phanerozoic diversity, ranging from the viability of literature-derived databases for investigating global diversity trends, to the biological significance of the myriad biotic transitions that have taken place throughout the Phanerozoic.

Such studies raise two concerns. The first is how model trees might bias results. The second is testing hypotheses about parameters that affect tree inference. Bias introduced by model trees is explored for tree-based assessments of the quality of the fossil record. Several nuisance parameters affect tree-based metrics, including consistency of sampling probability, rates of speciation/extinction, patterns of speciation, applied taxonomic philosophy, and assumed taxonomy. The first two factors affect probabilistic assessments of sampling, but also can be tested and accommodated in sophisticated probability tests. However, the final three parameters (and the assumption of a correct phylogeny) do not affect probabilistic assessments. Often paleobiologists wish to test hypotheses such as rates of character change or rates of preservation. Assumptions about such parameters are necessary in simple phylogenetic methods, even if the assumptions are that rates are homogeneous or that sampling is irrelevant. Likelihood tests that evaluate phylogenies in light of stratigraphic data and/or alternative hypotheses of character evolution can reduce assumptions about unknowns by testing numerous unknowns simultaneously. Such tests have received numerous criticisms, largely based in philosophy. However, such criticisms are based on incorrect depictions of the logical structures of parsimony and likelihood, misunderstandings about when arguments are probabilistic (as opposed to Boolean), overly restrictive concepts of when data can test a hypothesis, and simply incorrect definitions of some terms. Likelihood methods can test multiparameter hypotheses about phylogeny and character evolution (i.e., rates, independence, etc.). The best hypothesis positing a single rate of independent character change (with no variation among character states) is determined for each topology. Hypotheses about rate variation among characters or across phylogeny, character independence, and different patterns of state evolution then are examined until one finds the simplest (i.e., fewest varying parameters) hypothesis that cannot be rejected given knowledge of a more complicated hypothesis. This is repeated for alternative topologies. An example is presented using hyaenids. Two trees are contrasted, one of which requires the minimum necessary steps and the other of which requires at least seven additional steps. Given either tree, likelihood rejects fewer than three general rates of character change and also rejects the hypothesis of independence among the characters. However, hypotheses of changes in rates across the tree do not add substantially to the tree likelihood. The likelihoods of the trees given stratigraphic data also are determined. Both morphologic and stratigraphic data suggest that the multiparameter hypothesis including the parsimony tree is significantly less likely than the multiparameter hypothesis including a different tree.

Unraveling the deformational style, pattern, and timing of structures has led to improved understandings of internal geodynamics, crustal make-up, stress patterns, and overall tectonic evolution for each planetary body, as well as comparisons of such aspects among different bodies. For Venus and Mars, tectonic activity may have even affected their atmospheres and climate. Cross-cutting and superposition relations among structures and map units provide a basis for determining structural history. However, as on the Earth, structure rejuvenation and erosion may obscure or complicate the record. For some bodies, such as Mars, the Moon, Mercury, and some outer planet satellites, surfaces are sufficiently cratered to determine distinct relative ages based on crater densities that can be applied to planetwide correlations. Planetary geologic mapping has been sponsored by NASA and managed by USGS for nearly four decades. Mapping conventions have attempted to conform to those applied to terrestrial maps where possible, but the dependence on remotely sensed data has created challenges. Mappers must infer structural types (e.g., fractures, grabens, rifts, strike-slip faults, calderas, and folds) primarily from morphologic data. Because of this, maps ought to separate observation from interpretation (e.g., linear trough vs. graben), but this has not been the common practice. Digital manipulation of mapped planetary structures is still in its early stages. As datasets continue to expand, we expect that mapping of planetary structure will proceed apace, driving new techniques and methodologies while grounded on established mapping principles.

This approach has been supplemented recently by assembling spatially and temporally more extensive data sets that are used to test specific hypotheses regarding major themes in plant and insect paleobiology. Here, we recognize four themes as particularly promising, namely examining (1) community evolution, (2) the radiations of major lineages of herbivorous insects and their host plants; and herbivore response to (3) sudden and (4) prolonged environmental change.An example of the first theme is the Late Pennsylvanian Calhoun Coal flora from the Illinois Basin, which has revealed an extensive array of unanticipated herbivore types on Psaronius tree ferns and thus the early evolution of several major types of plant-insect associations. The second theme is represented by the diversification of hispine beetles and their angiosperm host plants during the Late Cretaceous, with implications for tracing the ecological extent, phylogenetic pattern, and geochronological timing of radiations among insects and their plant hosts. The third theme is explored with an example from the Williston Basin of North Dakota, where the end-Cretaceous mass extinction resulted in the diminution of most feeding types and the severe restriction of specialized plant-insect associations. The fourth theme is illustrated by an example from the greater Green River Basin of Wyoming, where Paleocene-Eocene global warming had a significant effect both on plant taxonomic composition and on the concomitant extent and intensity of insect herbivory. All four case-studies integrate data from the geological record, ecological and systematic evaluation of plant taxa, interpretation of insect-mediated damage, and analog studies of modern ecosystems and living relatives. These new and interdisciplinary approaches provide increasing understanding of how the triad of physical environment-plants-insects are linked during the long history of terrestrial ecosystems.

The oldest deposit is the Burdigalian Punta Alegre Formation, consisting of muddy ooze and mudstone that contains abundant and diverse nannofossils and planktonic and benthonic foraminifera, yielding an age of 19.5-18 Ma. Deposition took place in lower to middle bathyal water depths. The overlying Valiente Volcanics consists of a heterogeneous suite of interfingering lithofacies characteristic of a tropical volcanic arc. The lithofacies are 1). Columnar basalt and basalt flow breccia; 2) Pyroclastics; 3) Coarse terrestrial, fluviatile and shallow marine volcaniclastics 4) Coral reef lenses with diverse large coral colonies; 5) turbidites and coarse debris flows . Detailed logging of eight sections located around the Valiente Peninsula and Popa and Deer Islands have established that from 18 to 12 Ma a volcanic archipelago emerged in the Bocas del Toro region. Rapid shallowing from lower to upper bathyal depths occurred from Burdigalian (19.5-16.4 Ma) to Langhian (16.4-14.8) time. From Langhian to middle Serravallian (12.2 Ma) no bathymetric change occurred but in the late Serravallian, about 12 Ma, bathyal deposits were replaced by extensive alternating sequences of terrestrial and nearshore marine sediments. The paleobathymetric history of the Limon and Panama Canal Basins follow a similar trajectory. Thus by the end of the Serravallian (11.2 Ma) an extensively emergent archipelago had formed from the Panama Canal Basin westward. Coeval deposits to the east in Darien, eastern Panama, and the Choco, northwestern Colombia, continued to be deposited in bathyal depths indicating a continued oceanic gap between the Central American Volcanic Arc and South America.

AN - 52064781; 2002-068232 AB - The northern Basin and Range extensional province is part of the diffuse plate boundary fault system between the Pacific and North America plates. It is bounded on the east by the Colorado Plateau (either a part of stable North America, or a separate microplate), and on the west by the Sierra Nevada-Great Valley microplate. At latitude 39 to 40 N the province is nearly 750 km wide, and is composed of some 25 north-south basin-range pairs. Over the past approximately 10 Ma, extension across the region appears to have been relatively homogeneous, with all major range-bounding faults showing evidence of activity in late Quaternary time, although average horizontal slip rates on any given fault are generally <0.3 mm/yr. Historic seismicity, on the other hand, is largely confined to two local sub-regions of the Basin and Range, the Central Nevada Seismic Belt (CNSB) and the Intermountain Seismic Belt (ISB). This concentration of seismicity near the east and west margins of the province suggests the Basin and Range is currently acting as a "microplate", with most, or all, modern deformation occurring in these belts. Recent paleoseismic studies and geodetic surveys, however, paint a different picture. Velocities from 14 continuous GPS sites of the BARGEN network define a southward widening region of broadly uniform contemporary strain in western Utah and eastern Nevada, with an extent much greater than that of the ISB, while individual baselines in the "stable" central Basin and Range define strain rates from 40 nstr/yr compression to 10 nstr/yr extension. Paleoseismic studies on the Wasatch fault indicate a strain release pattern characterized by approximately 10 ka-long "bursts" of seismicity, interrupted by equally long periods of quiescence. The sum total of these data suggest that the categorization of Basin and Range behavior as "diffuse" or "microplate-like" is, at present, dependent on both the time-scale of observation, and the criteria used for differentiation of these behaviors.

This contrasts with the individualistic hypothesis that represents communities as happenstance associations of species with similar resource and climatic requirements. Studies of modern systems indicate that the composition of any local community is a subset of the composition of the regional species pool. Another control is evolutionary. Major plant clades divided up ecological resource space during the Late Devonian, when all vascular plant body plans (classes and orders) appeared. This can be seen as an historical constraint, which began to decay in the late Paleozoic. The early system was replaced by a similar kind of partitioning, but within one major clade, the seed plants. Today flowering plants, one group of seed plants, are following a similar pattern of partitioning. Thus, the first control was historical; early patterns of resource partitioning by clade limited possible membership by habitat. With the evolution of strong regional, provincial differences in floras, species pools exerted a second level of influence. Both of these factors point to access as the major assembly rule. First, do species have physiological access, mostly a product of historical evolutionary events. Second, can species physically reach a site, a consequence of biogeography. An additional factor is incumbency, which may be considered broadly to be competition. Incumbent late Paleozoic species, or multispecies clades (genera and families), persisted in their ecological roles for millions of years, roles established during a time of low resource saturation. Not until hegemony over resources was removed by extrinsic environmental effects did resources become available for reallocation. The recurrence of such phenomena is revealed by the examination of disassembly and subsequent reassembly patterns at different times in land-plant history. These patterns suggest that physiological access is the first filter. Geographic access is the second filter. Effects of incumbency provide the third filter. Thus, the same kinds of rules proposed to operate in ecological time also appear to operate in geological time. These do not negate individualistic dynamics. Rather, they suggest that such dynamics are spatio-temporally bounded.

We estimate Sierra Nevada-Great Valley microplate motion of 11.7+ or -0.1 mm/yr oriented N40W with respect to the Colorado Plateau. We also estimate a total deformation across the eastern part of the northern Basin and Range province of 3.3+ or -0.1 mm/yr oriented N77W. The rate difference provides us with an estimate for the total deformation across the ECSZ, including its norhtern extension through the Walker Lane belt, of 9.3+ or -0.1 mm/yr oriented N28W. This ECSZ deformation is accommodated across a region of about 150 km in breadth in the Death Valley region with right lateral shear strain rates in excess of 50 nstr/yr. The shear zone widens to more than 300 km to the north accommodating shear strain at rates of around 25 nstr/yr. We observe little extension in the direction perpendicular to the shear zone in both these northern and southern regions. However, we observe about 7 nstr/yr extension in the direction of shear from southeast to northwest, comparable to the northern Basin and Range average extension rate of about 10 nstr/yr.

This pattern, which applies to both total number of species and mean diversity of published floras, has remained similar with addition of new data. Although additional descriptive work is unlikely to change the pattern, major features of the diversity curve may reflect non-biological factors. Niklas et al. (1980) noted that sampling periods represented by large areas of continentally deposited rocks had high diversity. We note that even the residuals around the regression of diversity against outcrop area relate to the preservation potential of plant megafossils. Coal-bearing periods with fossiliferous rocks (Carboniferous, Cretaceous, and Paleogene) have higher than predicted diversity for the amount of continentally deposited rock. Intervals with lower than predicted diversity, such as the Permian-Jurassic, are characterized in many areas by red beds or deposits with low preservation potential. Much of the "signal" in the curve describing global diversity of land plants may reflect changes in sample size, and for the Cenozoic, an increasing range of preserved environments. Important questions about land plant diversity remain to be answered: for example, how much of diversity increase is within-habitat, and how much reflects the increasing range of habitats occupied over geological time? To answer such questions we need data gathered according to a standardized protocol. Leaf fossils seem most appropriate for this effort. Samples should be small but numerous, span a similar latitudinal range in each sampling period, and should be drawn from a similar set of depositional environments. Preliminary data suggest that some lowland, wetland habitats have little more diversity in the Cenozoic than in the Carboniferous, which is consistent with the global increase in land plant diversity resulting from the expanding range of habitats occupied.

The Evolution of Terrestrial Ecosystems (ETE) database provides a standardized basis for comparing continental faunas, floras, and ecosystem structures through the Phanerozoic. ETE's customized, multirelational format is locality-based and includes ecomorphic characters that allow comparisons across different taxonomic groups and over long spans of geological time. The ETE database has captured most published African Plio-Pleistocene fossil localities (>1100) and is used to examine the relationship between global-scale climate change and evolution. This research reveals a complex relationship between global climate trends and patterns of African species turnover and ecomorphic change, with differences in regional response times to climate forcing. It also reveals the effects of many "filters" imposed on the data during collection of the fossils and compilation and standardization of the data. These filters can impose biases more serious and more cryptic than those caused by taphonomic processes or the sampling unevenness inherent in the stratigraphic record. For the African mammal record, there are significant differences between published records in the ETE database and the more complete museum records, which affect biostratigraphic datums as wells as accurate characterization of the paleoecology of the different regions. Stepping up from individual sequences or basins to regional and continental compilations of the faunal/floral data typically lowers temporal resolution and requires multiple decisions and assumptions regarding collecting methods, taxonomy, and reporting of original field data. A continuing challenge for database research is to find the right balance between standardizing the data and maximizing its fidelity with respect to original information and continuing revisions to this information.

However, there are no examinations of insect-mediated damage from particular plant-host lineages throughout this interval, when folivory was initially launched in the equatorial wetlands and subsequently invaded more xeric riparian habitats of Euramerica. We examined a 45 million-year interval in several environments inhabited by the medullosan pteridosperm pinnule Neuropteris a dominant to subdominant member of late Middle to Late Pennsylvanian floras, whose abundance declined during the Early Permian. The earliest feeding styles occur during the late Middle Pennsylvanian, and are best illustrated by Mazon Creek material from the late Middle Pennsylvanian of the Illinois Basin. Although types of damage on Neuropteris have been introduced in a piecemeal manner in the literature, our examination of these pinnules yielded 160 specimens that exhibit a significant range of insect-mediated consumption of live tissue. Preliminary visual inspection and morphometric analysis document at least three types of damage. The insect damage includes marginal feeding corresponding to the ichnogenus Phagophytichnus Amerom. Well-preserved and thickened callus tissue surrounding this damage indicates a wound response from a live plant. A second type, known as Cuniculonomus Strauss, also preserves callus tissue, but instead borders a U-shaped region of necrotic plant tissue whose veins remain visible, probably reflecting surface abrasion or perhaps a leaf-mining trace. A third type, albeit rare, is non-marginal hole-feeding with callus tissue outlining circular to polylobate damaged areas. A fourth possible type of damage, poorly documented at present, is skeletonization. This ongoing study has also captured the size and shape of herbivory with respect to that of the entire pinnule, the location of damage on the pinnule, and recurring themes in the fine detail of the damaged margin. From the types of damage observed and knowledge of mouthparts of coeval insects, we suggest that the culprits were the orders Protorthoptera, Orthoptera, or Hypoperlida.

Offset Quaternary alluvial fans indicate relatively young activity on the fault, but the fault is seismically quiet at present. Seismicity is confined to the San Miguel-Vallecitos fault, a young, small offset fault to the north that is better aligned with plate motion. GPS measurements between 1993 and 1998 indicate that the ABF is locked and accumulating elastic strain. Transects of simultaneously occupied sites spanning the fault fit simple elastic half space models with rms misfits of 0.1-0.3 mm/yr. The long term slip rates estimated from these data are sensitive to the assumed rheological model. Simple elastic half space models suggest that both faults slip at about 3+ or -1 mm/yr. In contrast, when we use a model that incorporates seismic cycle effects and accounts for viscoelastic behavior beneath the brittle upper crust, preferred slip rate for the ABF increases to 6+ or -1 mm/yr, with correspondingly slower rates for the San Miguel-Vallecitos fault. Thus, incorporation of seismic cycle effects may be important when using geodetic data to infer long term fault slip rates. Evidence for relatively fast slip on the ABF, combined with evidence that it is in a relatively late stage in its earthquake cycle, suggests that it is a seismic hazard. Numerical simulations with a finite element model suggest that, if rheological and friction conditions for each fault are similar, slip on the San Miguel-Vallecitos fault is favored, reflecting its alignment with plate motion direction. Predicted motion on the ABF only approaches or exceeds the San Miguel-Vallecitos fault if the ABF has lower resistance to slip. The ABF has been active for at least two million years, while the San Miguel-Vallecitos fault is probably less than 250,000 years old. Perhaps long-lived faults have reduced resistance to slip.

These velocity fields were compared to the modern velocity field defined by four BARGEN continuous GPS sites which span the same region. Four years (1996-2000) of geodetic data yield a uniform velocity field across the region, with west velocities increasing linearly from 0.14 mm/yr at CAST (on the Colorado Plateau) to 4.1 mm/yr at EGAN (near Ely, NV), or approximately 11 nstr/yr. These results agree with the late Quaternary velocity field, which suggest approximately 4 mm/yr of horizontal displacement between Ely and the Wasatch front. This displacement is distributed fairly evenly on at least 5 major normal faults which span the transect (including the Sevier Desert detachment and Wasatch fault). The Holocene velocity field, however, is dominated by extension on the Wasatch fault and Sevier Desert detachment, which, over the past 10 ka, have been slipping at 3 to 4 times their average long-term rate. The agreement between modern geodetic rates and Quaternary-averaged fault slip rates suggests that strain accumulation across the eastern Basin and Range is relatively constant through time. High rates of Holocene seismicity may reflect "clustering" of events, during which strain release rates greatly exceed strain accumulation rates. Such clusters would be separated by periods of near dormancy on the faults, such that long-term average fault slip rates are substantially lower than those during a cluster. Geodesy, therefore, can provide a constraint with which to assess the accuracy and completeness of geologically derived velocity fields. Such a constraint is particularly useful in areas of relatively low strain, where neither the Holocene paleoseismology record, nor historic seismicity, are likely to be representative of strain distribution over longer time scales.

Such estimates allow for a regional rather than local description of environmental conditions, and they provide calibration points for global circulation models that are in turn used to infer the causes of climate change over time. Any single proxy for paleotemperature, such leaf margin analysis or the oxygen isotope analyses of biogenic apatites, is generally restricted in either time or space due to the vagaries of the fossil record, and the creation of such a broad framework of data for the Eocene requires a comparison of both kinds of estimates. To test the validity of such a comparison, fossil remains of similar age (Lysitean) were analyzed from the Big Horn Basin (BHB) of North America. Based on the percentage of entire-margined plant taxa, mean annual temperature (MAT) is estimated to have been approximately 19 degrees, while MAT estimates made using oxygen isotope ratios of coexisting mammal and fish remains provides a temperature estimate of approximately 17 degrees C. Therefore MAT estimate made using these two very different methods do appear comparable, and can be used to make a regional paleotemperature framework. To expand this framework further, preliminary isotopic measurements are being made on mammal, turtle, and fish samples from the Green River and Powder River Basins. Earliest Eocene fish scales from the Powder River Basin have oxygen isotope values approximately 1.5 per mil higher than stratigraphically younger (Greybullian) fish scales, and these higher values likely represents global warming of the Paleocene/Eocene Thermal Maximum.

These locations represent a wide range of geographical distances to the Pacific subducting margin (175 to 610 km) and of oxygen fugacities of the xenoliths (DFMQ from 2.19 to 0.78). H2O contents of enstatite (Opx) and diopside (Cpx) vary from 38 to 265 ppm and from 140 to 534 ppm, respectively. The Cpx water contents are significantly less in the Simcoe harzburgites than in the Mexican xenoliths. Cpx water contents correlate positively with those of Opx. Broad correlations between Opx and Cpx water contents with indices of fusion of the bulk xenoliths such as MgO (negative), Al2O3, TiO2, CaO, and Na2O (positive) contents indicate that the pyroxenes did not exchange hydrogen significantly with their host basalt on their way to the surface. These correlations also confirm that water is incompatible during melting of peridotite. The scatter of the data about these correlations, however, suggests that processes in addition to melt removal are responsible for the pyroxene water contents. In particular, the water contents of Cpx and Opx correlate negatively with oxygen fugacities calculated from microprobe and Mossbauer analyses of spinels, suggesting that the more oxidized a mantle environment, the less hydrogen is being incorporated into pyroxenes. This is consistent with published experimental data suggesting that water incorporation in Cpx and olivine depends mainly on the redox reaction between Fe3+ and Fe2+ in these minerals. Interaction of oxidizing fluids or melts from the slab with the mantle wedge may induce the reequilibration of water content and Fe oxidation in pyroxenes, resulting in a reduced amount of water being stored in the pyroxenes.

These post-tectonic to anorogenic granites are typically emplaced at shallow levels and often develop miarolitic cavities, aplitic units and pegmatites. Although the pegmatites may intrude the surrounding country rock for short distances, most are generally hosted by the parent granite. The hypersolvus to subsolvus pegmatite-generating granites tend to be heterogeneous and include peralkaline to weakly peraluminous compositions. A-type granites which generate pegmatites are characterized by the presence of biotite and amphibole as the dominant mafic phases. Fayalite-bearing facies are less common. Accessory phases include Fe- and Ti-oxides, REE-bearing oxides, phosphates and silicates, and fluorite. The characteristic A-type chemical signature is reflected in the associated pegmatites (NYF-type) which are enriched in Nb>Ta, Y, REE, Sc, Ti, Zr, Be, Th, U, F. The high Ga content of the A-type granite is also reflected in the trace element chemistry of the related pegmatites and may be used to help delineate them from pegmatites of the LCT geochemical affiliation. Pegmatites hosting fayalite, amphibole and REE mineralization are generally associated with peralkaline to metaluminous granites, while the more fractionated, weakly peraluminous granites generally spawn the more chemically evolved pegmatites that are enriched in Be, B, Sn and F. Extensive fractionation of these types may lead to bulk compositions and accessory mineralogy comparable to highly fractionated LCT-type pegmatites generated by S-type granites.

In the northern part of the study area, the K-Ar ages of illites from Devonian K-bentonites are similar to the ages of illites from Ordovician K-bentonites. All of these ages correspond to the time range for of the Alleghanian Orogeny. The K/Rb ratio of these illites was measured from these illites as an indication of whether they formed from saline waters (brines) or from meteoric waters. Though the K/Rb ratio is variable, it is near 250 in most illites according to R. C. Reynolds (N = 18, mean = 255, standard deviation = 41), and this has been verified by the measurements of other diagenetic illites (illite-smectites) from bentonites from the western United States (N = 13, mean = 275, and standard deviation = 114). The difference between these two populations is not significant. The mean K/Rb of illites from this study is 325 (N = 20, standard deviation = 91), and the higher K/Rb ratios indicate these illites formed from saline waters rather than meteoric waters. The difference in the K/Rb ratios between the Appalachian illites and non-Appalachian illites is significant at the 1% level. In combination, the data indicate these illites formed largely from the interaction of basin brines with the K-bentonites during the Alleghanian Orogeny. An additional effect of burial forming on the formation of these illites is more evident in the northern part of the area of study, where the K/Rb ratios is are lower and the indexes for burial (CAI) are high (4-5). Higher K/Rb ratios, lower CAI values (<3), and somewhat older K-Ar ages that correspond to the peak of orogenic activity in the southern part of the area of study imply that burial was of little consequence to illite formation within the bentonites there.

A previous study of the Meishan P/T boundary reported brief but dramatic d13C excursions of -5 and 6 at and slightly above the approximate level of the mass extinction horizon (in Beds 25/26 and 27) [1]. These excursions have not been observed in other P/T sequences. They have been variously ascribed to large methane bursts, extraordinary ocean-overturning events, or impacts of large carbon-rich comets. Despite multiple resampling, these excursions were not reproducible by our study. We infer that the extreme d13C excursions previously reported for Meishan probably did not result from real carbon events at the P/T boundary. The P/T d13C record of Meishan generally resembles those of numerous sections in southern Europe and Asia [2]. The d13C values of Meishan bulk carbonates decreased by about 2 (from 2 to 0 ) at the approximate time of the P/T mass extinction. Comparison of our Meishan record to U/Pb radiometric dates [3] indicates that d13C values of bulk carbonates remained close to 0 for slightly more than a million years into the Triassic. The simplest explanation of this long interval of low d13C values is a small but long-lasting decrease in the global organic carbon burial rate.

The fauna consists of soft-bodied impressions of variable size and morphology typically occurring on the soles on thinly-bedded sandstones or occasionally in turbidite deposits. The fossils range from the Neoproterozoic to the earliest Cambrian and have been recognized globally with particularly abundant assemblages in southern Namibia, southern Australia, and the White Sea region of Russia. The purpose of this research is to recognize trends in the spatial and temporal occurrence of Ediacaran fossils with the goal of gaining a better understanding of Ediacaran patterns of evolution and radiation. Data was collected in a literature review of 100 genera from forty geographic localities and thirty-one stratigraphic formations. Single occurrence taxa were eliminated to avoid statistical biases. The resulting data matrix consisted of twenty-nine localities, twenty-seven formations, and 117 specimens of 37 genera. This information was compiled into three matrices: one accounting for each formation at individual localities, a second grouping all formations within each locality, and a third describing each formation regardless of geographic setting. Data was analyzed with hierarchical cluster analysis (HCA) and multi-dimensional scaling (MDS). HCA provides distinct groupings, or clusters, of data entries, while MDS allows the analyst to decide which groupings are appropriate and on what basis they vary. The guidance of HCA in conjunction with the freedom of MDS has proven to be very successful in ecological studies. Unexpectedly, the Ediacaran fauna shows no trends in geographic locality. There are several cosmopolitan genera resulting in diverse assemblages. The main factor on which these assemblages differ is the degree of morphologic complexity. Discrepancies among chemically correlated formations and unexpected patterns in morphologic occurrence suggests strong variations in ecologic, and therefore, taphonomic, circumstances between localities.

A phylogenetic hypothesis based on Recent taxa only, however, may be overturned by the addition of fossils to the data set, as fossil taxa often possess combinations of characters not present in Recent species (1, 2). The present study uses a phylogeny of 54 Recent and fossil species of Soritacea (Foraminifera) to examine the impact of including fossils in an analysis on interpretations of heterochrony. Fossil taxa were sequentially added to a phylogeny of the Soritacea based on Recent taxa only. The relative effect of including fossils in the analysis differs within the subclades Spirolinida, Orbiculinida, and Soritida. In the subclade Archaiasinina of the Orbiculinida, fossil taxa are shown to be critical not only for resolution of branching order, but for correct interpretations of paedomorphic trends within the clade. In the Soritida, fossils are essential for resolving the relationships of the crown taxa, but do not affect the recognition of a peramorphic trend within the clade. In the Spirolinida, the inclusion of fossil taxa have no effect on tree topology. The relative degree of morphological change exhibited by each subclade appears to be correlated with stability of ecological habitat and/or a shift in endosymbiont type.Analyses based on Recent taxa only (i.e., most molecular studies, many morphological studies) may be biased due to the incompleteness of the living record (extant taxa = 1-2% of all life). An integrated paleontological and neontological approach may be critical to understanding the evolutionary history of a clade. Future phylogenetic studies should focus on groups with both extant and fossil members in order to explore the relative payoffs and pitfalls of relying on datasets comprised of Recent taxa only.

The greatest returns in understanding any given phenomenon will generally transcend frequency-dependent disciplinary boundaries, challenging modern tectonic researchers to develop coordinated, "broadband" observatories such as Earthscope's PBO. BARGEN, a prototype effort along these lines, is collecting continuous GPS and paleoseismological data across the northern Basin and Range province, which generally suggests a relatively homogeneous contemporary and late Quaternary extension across the province near 10 nstr/yr. A region of apparent range-normal crustal shortening, however, at up to 30-40 nstr/yr, appears to be well developed across north-central Nevada, in a region where the paleoseismology clearly indicates Holocene extension. The simplest explanation for the conflicting geodetic and geologic velocity fields is that the region of shortening is the contractional side of a viscoelastic wave diffusing eastward from the sites of the 1915 Pleasant Valley and 1954 Dixie Valley earthquakes. These results, if correct, suggest intracontinental areas with low strain rates and large earthquakes have extraordinary potential to elucidate fault system behavior, for example how transient coseismic and viscoelastic effects from one fault influence patterns of stress and strain release on others.

In the present investigation of the Rhone plain, southern France, surficial sediments that record anomalously old dates (to <4000 BP) occur preferentially on flooded surfaces where old carbon has accumulated. This old carbon is a component of recently eroded, fluvially-derived sediment that has been redeposited farther downvalley. In contrast, most radiocarbon-dated samples (plant and organic carbon) from artificially contained surfaces on the Rhone plain are of modern age. Modern radiocarbon dates prevail at artificially diked localities where (1) soil layers form on plain surfaces that are not periodically buried by flood deposits, and (2) accretion rates of recently deposited sediment incorporating reworked old carbon are minimal. Modern radiocarbon dates obtained at the Rhone deltaic plain provide chronostratigraphic markers against which Holocene dates from subsurface strata can be compared and spurious dates eliminated. The presence of such dates at many sites also provides a means with which to measure recent movement of land surfaces relative to sea level. Reliable dating of surficial sediment on artificially contained surfaces is one of the critical measures needed to help plan realistic protection for lower-lying sectors of the Rhone delta in danger of inundation.

This phenomenon is evaluated here by semiquantitative study of the variability of petrologic characteristics in different delta subenvironments of the Nautla and Tecolutla deltas along Mexico's Veracruz coast. Sediment composition and texture in the different environments of both deltas are related to processes that involve selective sorting during seasonal flooding and temporary storage after deposition. Displacement of particles of different size, density and shape onto the two tropical delta plains is controlled by fluctuating fluvial discharge that responds to a highly variable seasonal rainfall pattern. These discharge variations induce changes in hydraulic equivalence and, consequently, the release of substantially different proportions of volcanic, mica, heavy mineral and grain-size fractions in the Veracruz delta settings. These phenomena, together with progressive dilution of sediment upon reaching the coast, result in significant modifications to the original petrologic attributes of fluvial loads as they are transported seaward. Comparable variations of composition and texture in subsurface Holocene sections would likely record former large-scale climate, rainfall and fluvial discharge fluctuations. Petrologic analysis of core sections recovered at Prehispanic sites on the two deltas could be used to detect past long-term flooding pulses and droughts, natural events that archaeologists suggest caused deterioration of subsistence resources, stratigraphic hiatuses, cultural discontinuities and human migrations in this region.

These characteristics should damp rates of speciation in allopatric and vicariant evolutionary models since dispersal should swamp diverging populations and prevent divergence. Yet the fossil record suggests that rates of evolutionary turnover in pelagic organisms are often quite rapid, comparable to rates observed in much more highly fragmented terrestrial and shallow-marine environments. Furthermore, genetic and ecological studies increasingly suggest that species diversity is considerably higher in the pelagic realm than inferred from many morphological taxonomies. Zoogeographic evidence suggests that ranges of many pelagic groups are much more limited by their ability to maintain viable populations than by any inability to disperse past tectonic and hydrographic barriers to population exchange. Freely dispersing pelagic taxa resemble airborne spores or wind-dispersed seeds that can drift almost anywhere but complete the entire life cycle only in favorable habitats. It seems likely that vicariant and allopatric models for speciation are far less important in pelagic evolution than sympatric or parapatric speciation in which dispersal is not limiting. Nevertheless, speciation can be quite rapid and involve cladogenesis even in cases where morphological data suggest gradual species transitions. Indeed, recent paleoecological and molecular studies increasingly suggest that classic examples of "phyletic gradualism" involve multiple, cryptic speciation events. Paleoceanographic and climatic change seem to influence rates of turnover by modifying surface water masses and environmental gradients between them to create new habitats rather than by preventing dispersal. Changes in the vertical structure and seasonality of water masses may be particularly important since these can lead to changes in the depth and timing of reproduction. Long-distance dispersal may actually promote evolution by regularly carrying variants of a species across major oceanic fronts and exposing them to very different selection pressures than occur in their home range. High dispersal in pelagic taxa also implies that extinction should be difficult to achieve except though global perturbations that prevent populations from reestablishing themselves following local extinction. High rates of extinction in some pelagic groups suggests either that global perturbations are common, or that the species are much more narrowly adapted than we would infer from current taxonomies.

A coccoid cyanobacterium, tentatively identified as Solentia sp., bores tunnels, which initially penetrate just beneath grain surfaces and eventually extend throughout the entire grain. These tunnels are filled by radial fibrous aragonite, which is precipitated as the microorganism advances. Extensive multicyclic repetitions of this process result in obliteration of original grain textures with almost complete preservation of grain margins and rare empty bore holes. The rapidly filled tunnels cannot be detected by resin cast embedding techniques that are commonly used to study microboring. This type of multicyclic boring and concurrent filling of bore holes forms micritized grains that can be difficult or impossible to distinguish from micritized grains formed by recrystallization.

Calibration was performed using long-term (WY1980-WY1990) hydrochemistry data from a gauged site. The calibrated model reproduced water yields, TN, and TP export with cumulative errors of <1% over the 11-year calibration period and with annual RMS errors of 10-50%. Model validation was done with independent measurements at the same gauged site (WY1991 to WY1996) and at another nearby independently gauged site (WY1991 to WY1995). Local adjustment of the groundwater recession coefficient and the dissolved N concentration in agricultural stormflow was essential for successful application at the second site. GWLF appears to be a useful model for estimation of fluxes of water, N and P from ungauged areas with accuracies of 10-50% at annual time scales.

At first glance, the surface of Mercury looks similar to the Moon. However, Mercury is unique among the planets in many ways, particularly with respect to tectonics. In fact, one of the most extraordinary characteristics of the surface of Mercury imaged by Mariner 10 is the presence of hundreds of landforms that reflect crustal deformation. Two types of deformation have been identified on Mercury, distributed and basin-localized. Landforms described as lobate scarps are distributed throughout the broad intercrater plains and younger plains materials. Lobate scarps are interpreted to be the surface expression of thrust faults, and the displacement length relationship of these thrust faults is consistent with terrestrial fault and thrust fault populations. Less common high-relief ridges may be the result of high-angle reverse faulting. In some cases high-relief ridges transition into lobate scarps. Distributed deformation on Mercury is thus predominately compressional. Mercury, like the Moon, has deformation localized by impact basins. The Caloris basin has an array of tectonic features both within and outside its rim. Wrinkle ridges, interpreted to be a combination of folding and thrust faulting, deform interior plains and the plains surrounding the basin. Narrow linear troughs in the interior plains are interpreted to be fractures or graben. Extensional features are largely absent elsewhere on the planet. The stresses that formed the lobate scarps and high-relief ridges are attributed to either global contraction due to secular cooling of the interior, relaxation of an equatorial bulge due to tidal despinning, or a combination of the two. The tectonic features associated with Caloris are attributed to the load of the interior and exterior plains material. Data return by the upcoming MESSENGER mission and ongoing Earth-based radar observations will greatly improved our understanding of tectonism on Mercury.

Unfortunately, this potential has not been fully exploited because of lack of well-sampled time series and adequate statistical analysis. Nevertheless, four basic patterns appear to be of general significance. First, a major pulse of extinction occurred 1-2 m.y. ago in many ocean basins, more or less coincident with the intensification of glaciation in the Northern Hemisphere. Rates of origination also increased greatly but were more variable in magnitude and timing. The fine-scale correlation of these evolutionary events with changes in climate is poorly understood. Similar events probably occurred on land but have not been tested adequately. Second, rates of origination and extinction in the oceans waned after the pulse of extinction, especially during the past 1 m.y. Thus, most marine species originated long before the Pleistocene under very different environmental circumstances, suggesting that they are "exapted" rather than adapted to their present ecological circumstances. The same may be true for many terrestrial groups, but not for the mammals or fresh-water fishes that have continued to undergo speciation throughout the Pleistocene. Third, community membership of late Pleistocene coral reef communities was more stable than expected by chance. These are the only paleoecological data adequate to test hypotheses of community stability, so that we do not know whether community structure involving other taxa or environments typically reflects more than the collective behavior of individual species distributions. Regardless, the strong evidence for nearly universal exaptation of ecological characteristics argues strongly against ideas of coevolution of species in communities. Finally, ecological communities were profoundly altered by human activities long before modern ecological studies began. Holocene paleontological, archeological, and historical data constitute the only ecological baseline for "pristine" ecological communities before significant human disturbance.

AN - 50070921; 2010-027652 AB - We compare the equilibrium climate responses of a quasi-dynamical energy balance model to radiative forcing by equivalent changes in CO (sub 2) , solar total irradiance (S (sub tot) ) and solar UV (S (sub UV) ). The response is largest in the S (sub UV) case, in which the imposed UV radiative forcing is preferentially absorbed in the layer above 250 mb, in contrast to the weak response from global-columnar radiative loading by increases in CO (sub 2) or S (sub tot) . The hypersensitive response of the climate system to solar UV forcing is caused by strongly coupled feedback involving vertical static stability, tropical thick cirrus ice clouds and stratospheric ozone. This mechanism offers a plausible explanation of the apparent hypersensitivity of climate to solar forcing, as suggested by analyses of recent climatic records. The model hypersensitivity strongly depends on climate parameters, especially cloud radiative properties, but is effective for arguably realistic values of these parameters. The proposed solar forcing mechanism should be further confirmed using other models (e.g., general circulation models) that may better capture radiative and dynamical couplings of the troposphere and stratosphere.

Using a special spectral incubator (photoinhibitron), rates of bacterial incorporation using {3}H labeled thymidine and leucine are measured under a range of UVR exposures. Incorporation of these substrates is indicative of DNA and protein synthesis, respectively, and measurements were made for both temperate and Antarctic marine systems. In this paper, we describe the approach and present some initial results. Overall, we have found significant inhibition of substrate incorporation by UVB and varying effects of UVA. More detailed comparisons of UV effects on thymidine and leucine incorporation were made using bacterioplankton from an upper Chesapeake Bay subestuary (Rhode River). These comparisons showed consistent differences in spectral dependence, with thymidine incorporation more sensitive to UVA than leucine incorporation. JF - [np]. 24-28 Jan 2000.

N1 - Last updated - 2016-12-21 ER - TY - JOUR T1 - Contrasting evolutionary flexibility in sister groups: disparity and diversity in Mesozoic atelostomate echinoids AN - 18209390; 5276918 AB - Temporal asymmetries in clade histories have often been studied in lower Paleozoic radiations. Post-Paleozoic patterns, however, are less well understood. In this paper, disparity and diversity changes in Mesozoic heart urchins were analyzed at the ordinal level, with contrasts among the sister groups Holasteroida and Spatangoida, their paraphyletic stem group Disasteroida, and the more inclusive clade, the superorder Atelostomata. A 38-dimensional landmark-based morphospace representing test architecture was used to describe morphological evolution in terms of total variance and total range. Discordances between disparity and diversity were evident and were expressed both as deceleration in morphological diversification in all groups and as disproportionately higher disparity early in the histories of the Atelostomata, Holasteroida, and Spatangoida. The finding that the early atelostomate disparity peak coincides with the origin of the orders Holasteroida and Spatangoida lends support to the perception of orders as semi-independent entities in the biological hierarchy and as meaningful proxies for morphological distinctness. A comparison of holasteroid and spatangoid responses to the end-Cretaceous mass extinction revealed morphological selectivity. Paleocene spatangoid survivors showed no change in disparity relative to the Campanian-Maastrichtian sample, suggesting nonselectivity. Holasteroids suffered a pronounced loss in disparity (despite a rather high Late Cretaceous level of disparity), indicating morphological selectivity of extinction. Partitioning of disparity into plastral and nonplastral components, reflecting different degrees of developmental entrenchment and functionality, suggests that the origin of holasteroids and spatangoids is more consistent with an exploration of the developmental flexibility of nonplastral constructions than with uniform ecospace occupation. Within groups, several patterns were also most consistent with intrinsic controls. For plastral landmarks, there is an apparent increase in developmental modularity and decrease in developmental constraint from disasteroids to holasteroids and spatangoids. For nonplastral landmarks, no substantial change in disparity was observed from disasteroids to holasteroids and spatangoids, suggesting the maintenance of a developmental constraint despite the passage of time and ecological differentiation. More generally, this study suggests that certain topologies of disparity and evolutionary mechanisms potentially characteristic of the lower Paleozoic radiations of higher taxa (e.g., developmental flexibility) need not be confined to any given time period or hierarchical level.

Metamorphism, partial melting and incomplete differentiation (i.e. incomplete separation of melt from residue) produced metallic, sulphide-rich and silicate partial melts as well as metamorphosed chondritic materials and residues. Catastrophic impact break-up and reassembly of the debris while near the peak T mixed materials from various depths into the re-accreted parent body. Thus, molten metal from depth was mixed with near-surface silicate rock, resulting in the formation of silicate-rich IAB irons and winonaites. Ages of silicate inclusions and winonaites of 4400-4540 m.y. Ga indicate this entire process occurred early in solar system history.

The chemical features of the spherules indicate that their precursor materials were characterized by extreme elemental fractionations under oxidizing conditions, which have not been observed in chondritic materials before. The liquidus T of the euhedral Fe,Ni-metal grains are lower than those of the coexisting ferrous silicates suggesting that the former crystallized in supercooled silicate melts. The metal grains are not decomposed into taenite and kamacite, suggesting fast postcrystallization cooling at T 400-500 K.

This meteorite experienced minor alteration and a low degree of thermal metamorphism (petrologic type 3.1) and escaped post-accretional brecciation. The alteration resulted in the formation of several minerals, including fayalite, hedenbergite which typically occur as veins. Fayalite and hedenbergite in MAC 88107 formed during late-stage, low-T ( approximately 150-200 degrees C) aqueous alteration. The data for MAC 88107 extend the evidence for an early onset of aqueous activity on chondrite parent bodies and reinforce the conclusion that liquid water played an important role in the chemical and mineralogical evolution of the first chondritic planetesimals.

In this Holocene deltaic system, most radiocarbon-dated samples do not become progressively younger upcore, and there is no direct relationship between age and depth. About one in 6 dates is too young, recording locally truncated stratigraphic sections. Of particular note are the nearly two-thirds of all radiocarbon dates that record ages that are much too old, by 1000 to 10,000 years (23% are of Pleistocene age). This phenomenon results from the introduction of old carbon during sediment storage and reworking along the dispersal path between headlands and the coast. Thus, rather than recording final time of Holocene deposition at deltaic core sites, dates in Yangtze delta sediment appear to indicate a time lapse that occurred during storage and transport cycles in the fluvial valley and delta plain. There is no simple, obvious or universal solution to this radiocarbon-dating problem in deltaic sequences. The problem warrants attention since reliable dating of Holocene sequences is essential for measurement of rates of sediment accumulation and delta margin subsidence relative to sea level, two of the parameters needed to help implement protection measures along the vulnerable low-lying Yangtze delta coast. At present, a multi-method dating approach (amino acid racemization, isotopic analyses, archaeological determination, and others) would constrain sediment age, and provide a more reliable measure of deposition time in such settings than by radiocarbon dating alone.

In North America, we identify 298 nonindigenous species (NIS) of invertebrates and algae that are established in marine and estuarine waters, generating many "apparent patterns" of invasion: (a) The rate of reported invasions has increased exponentially over the past 200 years; (b) Most NIS are crustaceans and molluscs, while NIS in taxonomic groups dominated by small organisms are rare; (c) Most invasions have resulted from shipping; (d) More NIS are present along the Pacific coast than the Atlantic and Gulf coasts; (e) Native and source regions of NIS differ among coasts, corresponding to trade patterns. The validity of these apparent patterns remains to be tested, because strong bias exists in the data. Overall, the emergent patterns reflect interactive effects of propagule supply, invasion resistance, and sampling bias. Understanding the relative contribution of each component remains a major challenge for invasion ecology and requires standardized, quantitative measures in space and time that we now lack.

To verify the general applicability of the method, we selected for study 343 samples from 13 cores in these two deltas that formed in markedly different geographic and climatic settings: the Nile delta in the highly arid and warm to hot region of Egypt; and, in contrast, the Ganges-Brahmaputra delta in the humid hot region of India and Bangladesh. Analyses indicate that pigments are composed of iron oxides, likely including goethite. Samples of late Pleistocene alluvial sediment show consistently higher proportions of both partially and fully coated quartz types than in the overlying Holocene deltaic deposits. This finding prevails regardless of factors such as sediment process, transport distance, lithology of sediment section examined, and sand grain texture. On the basis of actual measurements made in the present investigation, it appears possible to recognize Holocene and Pleistocene strata by counting the 3 sand-sized quartz grain types (325-350 grains/sample) in as few as 10 to 20 small samples that are distributed downcore in a minimum of 3 to 6 borings. The method is simple, rapid, inexpensive, and particularly well suited for stratigraphic interpretation of sediment sections that are incomplete and/or poorly dated.

Regional distribution of these facies indicates that neotectonic displacement, including differential land subsidence, of delta plain sectors is one of the major controls of late Quaternary depositional patterns in this depocenter. The spatial and temporal configuration of Holocene deltaic sediment thickness, mud and sand layers, peats interstratified in Holocene sequences, and modern mangrove forests that form the Sundarbans are attributed to NE-SW, and to a lesser extent NW-SE, neotectonic trends. Holocene sedimentary and stratigraphic configurations closely parallel geological structures, some of them deep seated, that affected this region during most of the Tertiary and have continued to the present. Extensive mangrove forests developed along the NE-SW zone of thickened Holocene deltaic deposits. Their present configuration is related to natural factors, such as eastward tilting of the delta, rapid sediment accumulation (to 0.7 cm/yr), marked land subsidence (to 0.5 cm/yr), and increasing anthropogenic influences, including large-scale land reclamation and decreased river flow influx. The diverse and extensive mangrove tracts of the delta have significant environmental and economic implications for the rapidly growing population, including serving as a buffer zone that helps to reduce the impact of landward-driven tides, storms and cyclones. Interpretation of Holocene facies in the subsurface by means of radiocarbon-dated cores provides a mean to more precisely define the interaction between contemporary Holocene depositional patterns and neotectonics. This information, in turn, can be utilized to develop realistic measures needed to minimize further degradation of this biologically unique ecosystem.

The association of leaf-chewing beetles with C. acuminatissima was verified with feeding trials. Of 59 species of leaf-chewing beetles that were collected, 36 species could be used in feeding trials. Only 9 of these species fed on C. acuminatissima. A further 27 beetle species were tested in feeding trials but did not feed. Of these, 7 were specialists feeding on other tree species within the surrounding vegetation. Most beetle species collected from C. acuminatissima foliage were probably transient species, dispersing from other tree species. Path analyses showed that herbivore abundance during a particular sampling period was significantly influenced by rainfall, leaf flush of other conspecific tress and air temperature, but not so by the species richness of surrounding vegetation, number of surrounding conspecific trees and size (DBH) of trees sampled. The species richness of leaf-chewing beetles collected on particular study trees depended on that of the surrounding vegetation, thus supporting the hypothesis that most beetle species collected were transient. The abundance of insect herbivores on particular C. acuminatissima trees probably depends on a balance between the leaf flush of conspecific trees and that of the particular tree sampled. The results also emphasize the need to remove transient species in analyses of insect faunas of tropical trees, at the risk of analyzing species richness patterns derived from loosely defined "assemblages" of species.

Our data include one group of amphibians, two groups each of fishes and flowering plants, and four groups of terrestrial arthropods. In contrast to many other Amazonian groups, the taxa analyzed here and the primate indicator group are well-known taxonomically (few to no known undescribed species, no nomenclatural problems). We apply a suite of statistical and graphical methods designed to detect undersampling bias and nonrandom geographic patterns in the data. Our results indicate that: 1) Some of the taxa in our data set are adequately sampled at the species level, others are not; and 2) all geographic ranges appear to be undersampled, including those for the indicator group. Currently available data adequately determine species richness at the level of the Amazon basin for heliconias, the plant genus Talisia, heliconiine and ithomiine butterflies, certain fish genera from both large and small rivers, the frog genus Leptodactylus, birds, and primates. In contrast, present data are inadequate for the arthropod genera Agra, Batesiana, Deinopis, and Hemiceras. We recommend that similar suites of analytical techniques be used routinely to assess the adequacy of data prior to their use in making conservation decisions. We conclude that museum data are adequate to use for conservation purposes for certain Amazonian taxonomic groups, which is an encouraging finding. For taxonomic groups with data that fail the adequacy tests, we recommend a bottom-up approach of analysis using expert evaluation of the available data.

We compared the frequency of gaps caused by wood borers to other gap-forming processes and characterized the physical attributes of light gaps in mangrove forests on small islands in Belize. Methods of quantifying light gaps included aerial photography, ground surveys, and experimental plots. Small light gaps ( less than or equal to 12 m super(2)) were very common in Rhizophora mangle fringe, comprising almost 22 percent of these forests. Rhizophora mangle gaps were smaller than gaps in Avicennia germinans forests. In R. mangle forests, gaps were caused by branch death, and in A. germinans forests, gaps were caused primarily by downed trees. More than 91 percent of the gap-forming branches and boles in the R. mangle fringe were killed by a wood-boring cerambycid beetle, Elaphidion mimeticum, indicating that it is the major cause of small-scale disturbances in these forests. No trees or branches in the A. germinans forest were attacked by this beetle. In R. mangle forests, small gaps had significantly higher light levels and soil temperatures than areas under the closed canopy; however, soil conditions for sulfide concentrations, porewater salinity, and redox potentials were similar in small gaps and under the closed canopy. Survival of R. mangle, A. germinans, and Laguncularia racemosa seedlings was also higher inside these small gaps, indicating their importance in regeneration of mangrove forests. Feeding by wood borers is thus an important type of indirect herbivory in mangrove forests, with a critical role in ecological processes such as gap dynamics.

Swamps in Nicaragua AN - 17492090; 4679900 AB - The palm Raphia taedigera Mart. forms vast, monodominant swamps in Central and South America, but very little is known about the ecology and natural history of these ecosystems. Debate surrounds the issue whether R. taedigera swamps are early successional stages or mature "climax" communities. This paleoecological analysis of a 1.46-m sediment core from swamps on the Caribbean coast of Nicaragua establishes the abundant presence of R. taedigera swamps for at least 2800 plus or minus 90 years. R. taedigera swamps must be considered persistent communities, warranting further study because of their great extension into Central and South America.

Greene (Portulacaceae) in Maryland AN - 17400562; 4633244 AB - Montia linearis (Portulacaceae), native to the western United States, is reported from a recurring population in Suitland (Prince Georges County), Maryland. The species is now known from four states west of the Mississippi River: Maryland, Massachusetts, Mississippi, and Tennessee. Given this distribution and evidence for weediness in its native range, additional occurrences in the eastern and south-central United States are to be expected. Although it seems likely that Montia linearis has been introduced into the eastern United States via human activity, this cannot be established at present: phylogenetic analyses of Portulacaceae indicate that long-distance dispersal has played a significant role in the biogeographic history of this family.

We extracted, amplified and sequenced mitochondrial DNA from fossil moa-nalo bones to determine their systematic relationships and lend insight into their biogeographical history. The closest living relatives of these massive, goose-like birds are the familiar dabbling ducks (tribe Anatini). Moa-nalos, however, are not closely related to any one extant species, but represent an ancient lineage that colonized the Hawaiian islands and evolved flightlessness long before the emergence of the youngest island, Hawaii, from which they are absent. Ancient DNA yields a novel hypothesis for the relationships of these bizarre birds, whereas the evidence of phylogeny in morphological characters was obscured by the evolutionary transformation of a small, volant duck into a giant, terrestrial herbivore.

The burrows serve as shelter and as a reproductive habitat, and females are known to host their offspring in their burrows. I examined the reproductive biology of S. terebrans in the Indian River Lagoon, a shallow lagoon stretching for similar to 200 km along the Atlantic coast of Florida, USA. Reproductive isopods were found throughout the year, but reproductive activity was highest in the fall and during late spring/early summer. During the latter periods, large numbers of subadults established their own burrows in aerial roots. The average numbers of S. terebrans per root were high during the fall, but decreased during the winter and reached lowest levels at the end of the summer. Females reached maturity at a larger size than males, but also grew to larger sizes than the males. The average size of females varied between 8 and 10 mm, the average size of males between 6.5 and 8.5 mm. The number of embryos female super(-1) was strongly correlated with female body length. No indication for embryo mortality during development was found. Parental females (i.e. with juveniles in their burrows) hosted on average between 5 and 20 juveniles in their burrows (range 1 to 59). Most juveniles found in female burrows were in the manca stage and 2 to 3 mm in body length. Juveniles did not increase in size while in the maternal burrow, and juveniles of similar sizes could also be found in their own burrows. Males did not participate in extended parental care, since most of them left the females after copulation. Many females that were born in the summer produced one brood in the fall and a second during winter/early spring. Females that were born in the fall produced one brood during spring/early summer, but then probably died. Extended parental care in S. terebrans is short compared to other peracarid crustaceans. It is concluded that this reproductive strategy in S. terebrans serves primarily to shelter small juveniles immediately after they emerge from the female body, when their exoskeleton is still hardening and their physiological capabilities are still developing. Thus, in S. terebrans, extended parental care probably aids to protect small juveniles from adverse physical conditions in their subtropical intertidal habitat.

Nevertheless, similarities between the different OAEs can be observed. Here, we have reconstructed paleoenvironmental changes during the early Albian OAE 1b using benthic foraminiferal distributions and lithologies in three sections from different basins and paleowater depths. Eutrophic conditions, as indicated by the presence of infaunal as well as opportunistic genera such as Gyroidinoides, Pseudobolivina, Pleurostomella and bolivinitids, prevailed before and during the OAE and led to dysoxic to anoxic conditions. Dysoxia was most intense in the bathyal sections but also occurred in the outer shelf where more heterogeneous patterns of foraminiferal distributions are believed to reflect fluctuations of the upper boundary of an oxygen-minimum zone. A change from eutrophic to mesotrophic conditions caused the termination of OAE 1b and opportunistic benthic foraminifera (e.g. Pseudobolivina, Pleurostomella) were the first to subsequently repopulate the bathyal sea floor. Repopulation occurred rapidly in the shallow settings and gradually in the deeper sites, where a normal, diverse pre-event fauna was established a few tens of thousands of years after OAE 1b.

Individuals of this species occurred almost exclusively as members of mixed-species flocks, occupying sites with greater densities of encino oak and ground cover and fewer pines than random sites. Most foraging observations were recorded in mid-story, encino oak. Commonly-observed foraging maneuvers were gleaning and sally-hovering. Eighty-three percent of foraging maneuvers were directed at the outermost portions of the oak foliage. Flocks in which Golden-cheeked Warblers occurred contained an average of 20.5 individuals and 12.9 species other than Golden-cheeked Warblers. The most frequently co-occurring species were Wilson's Warbler (Wilsonia pusilla), Black-throated Green Warbler (Dendroica virens), Hermit Warbler (D. occidentalis), Townsend's Warbler (D. townsendi), and Blue-headed Vireo (Vireo solitarius). The ratio of males to females observed was not substantially different from 1:1, and there was little evidence of sexual differences in habitat use. Golden-cheeked Warblers appeared to be tolerant of moderate levels of logging and grazing, but understory clearing to promote grazing for cattle may pose a significant threat to winter habitat availability.

Here the design of a pot experiment is described that simulates the daily time course of irradiance and light quality in idealized gaps of six different sizes. Differences in response to gap size are illustrated using data from two pioneer species, Ochroma pyramidale, which recruits exclusively in large gaps and clearings, and Luehea seemannii, which colonizes small branchfall gaps as well as large gaps. Ochroma outperformed Luehea in relative growth rate in all except the smallest simulated gap size. Ochroma's superior performance in the larger gaps could be attributed to a larger proportional investment in leaf biomass (i.e. a higher leaf area ratio, LAR), and higher photosynthetic rates both on a leaf area and leaf mass basis. In the smallest simulated gaps LAR was not significantly different between the species, but Ochroma maintained a higher net assimilation rate. These results fail to support the suggestion that gap partitioning among pioneer species arises directly from morphological and biochemical specialization to particular gap light environments. Instead, it is suggested that partitioning may result from a trade-off between seedling growth and mortality determined by species allocational patterns and mediated by interactions with herbivores and pathogens.

This joint Canada-US initiative aims to conserve the habitat corridors that are dwindling in this region. For larger mammals such as the grizzly, these corridors connect the vast habitat tracts that are required for the survival of the species. The trail runs from Yellowstone National Park through Montana, Alberta, and British Columbia, terminating at Watson Lake in Yukon Territory. Harvey Locke, the initiator of the trail concept, supports his initiative with evidence on the habitat requirements of wildlife, and finds commonality with the 1991 Wildlands Proposal, which aims to establish a network of wilderness preserves.

These pollutants accumulate in marine mammals, and belugas are at the top of the food chain. The St. Lawrence River population is considered a remnant population, and doesn't mix with the large beluga populations farther north. It remains within the St. Lawrence system throughout the winter. Once hunted and systematically killed out of the misperception that they were threatening the commercial fisheries, the species was protected in 1983. Protective measures have helped the population increase from 300 to an estimated 1200 in the past two decades. The unique individual and group characteristics of the belugas have been observed by researchers on the Bleuvet, a research vessel.

On the edge of the Pacific tectonic plate, Big Sur is literally on the cutting edge of the nation, the landscape showing the imprint of this chaotic movement of wind, water, and earth. An unusually complex ecosystem has evolved here, with representations from the wet north and the desert south, and the endemic and unique Santa Lucia fir. The rugged landscape has been a challenge for settlers, yet continues to attract those who thrive on the edge. Poet Robinson Jeffers arrived in 1914, and gave voice to the beauty and drama of the landscape. Other artists have made their home here, maintaining a stronghold against development and exploitation under the growing tourism trade.

The coastal fortification was founded to protect against European invasion, and lies within the Dry Tortugas ecosystem. The old fort is gradually crumbling; its 16 million bricks barely held together by decomposing mortar. All equipment and materials for the slow renovation and the living requirements of the minimal staff must be shipped in at a high cost. This region is home to sooty turns, brown noddies, loggerhead and green turtles, and many migratory bird species. Heavy tourist pressure threatens these species, and poaching on lobsters is common. The Florida Keys National Marine Sanctuary has proposed the establishment of a preserve to protect marine diversity.

Because of unusually good foraminiferal preservation for sediments of this age, we have obtained an unaltered oxygen and carbon isotope profile and an accompanying record of planktic and benthic foraminifer abundance changes across the OAE 2 interval. Biostratigraphic, sedimentologic, and chemostratigraphic analyses indicate that more than 0.5 m.y. between the onset and tail end of OAE 2 are missing. This explains why organic-rich sediments are absent from the Site 1050 sequence and why the planktic and benthic carbon isotope shifts are minor ( approximately 0.8 per mil) compared with the most complete OAE 2 sections. While planktic species diversity shows relatively minor change across the OAE 2 interval, extinction of the rotaliporids and Globigerinelloides bentonensis, a shift to Heterohelix-dominated assemblages, and increased abundance of helvetoglobotruncanids at the onset of OAE 2 cause a dramatic change in the planktic foraminifer assemblage composition. The rotaliporid extinction occurs at the level where middle bathyal temperatures are estimated to have increased from 15 to 19 degrees C, which is warmer than any other time during the Cretaceous and Cenozoic. This deep water warming may have caused a breakdown in the vertical structure of the water column, and could explain the extinction of deeper dwelling planktic species, including Rotalipora and G. bentonensis. On the other hand, sea surface temperature estimates based on planktic foraminiferal delta (super 18) O values (corrected for salinity) remain steady throughout the CTBI, varying between 23 to 26 degrees C. The presence of volcaniclastic sediments within the OAE 2 interval at Site 1050 is consistent with previous suggestions that the CTBI was a time of anonymously high rates of CO (sub 2) flux into the atmosphere and oceans during a major phase of explosive volcanic activity and large igneous province emplacement in the Caribbean and other regions worldwide. Further investigation of the CTBI is needed to establish whether increased PCO (sub 2) can be accepted as the primary forcing mechanism for the middle Cretaceous "supergreenhouse".

Effects of homobatrachotoxin on chewing lice (order Phthiraptera) AN - 17489289; 4679028 AB - Birds in the genus Pitohui carry the potent neurotoxin homobatrachotoxin in their skin and feathers. In this study, I tested whether homobatrachotoxin can repel or kill chewing lice (order Phthiraptera). When individual feather lice were offered a choice of two feathers on which to feed or take shelter, the lice preferred nontoxic feathers to feathers of the most toxic pitohui species, Pitohui dichrous. Moreover, the presence of toxic P. dichrous feathers significantly shortened the life span of captive feather lice. These results suggest that homobatrachotoxin repels and kills lice and may thus protect pitohuis against lice infestation.

During general flowering, which occurs at irregular intervals of 3-10 yr, nearly all dipterocarp species together with species of other families come heavily into flower. We monitored reproductive phenology of 576 individual plants representing 305 species in 56 families in Sarawak, Malaysia. Observations continued for 53 mo from August 1992 and covered one episode of a general flowering cycle. Among 527 effective reproductive events during 43 mo, 57% were concentrated in the general flowering period (GFP) of 10 mo in 1996. We classified 257 species into flowering types based on timing and frequency of flowering. The most abundant type was "general flowering" (35%), which flowered only during GFP. The others were "supra-annual" (19%), "annual" (13%), and "sub-annual" (5%) types. General flowering type and temporal aggregation in reproductive events were commonly found among species in various categories of taxonomic groups, life forms, pollination systems, and fruit types. Possible causes for general flowering, such as promotion of pollination brought about by interspecific synchronization and paucity of climatic cues suitable for flowering trigger, are proposed, in addition to the predator satiation hypothesis of Janzen (1974).

To address this question, we developed microsatellite primers to infer paternity in remnant populations of the Amazonian tree Dinizia excelsa (Fabaceae). Dinizia is one of the most phylogenetically isolated Legume genera, marking the divergence between the Mimosoid and Caesalpinioid subfamilies (Herendeen & Dilcher 1990). D. excelsa is endemic to terra firme rainforests of the central Amazon, is insect pollinated and bears indehiscent pods that are wind dispersed. Members of this species include some of the largest trees in Amazonia, attaining 60 m in height and 2.5 m in diameter (Ducke 1922). The prized hardwood accounts for approximately 50% of regional timber sales (Barbosa 1990). Because of their value for timber and shade, large individuals are often left standing in pastures. Shade trees, along with individuals in continuous and fragmented forest, provided an experimental system to examine the breeding structure of remnant populations (Dick 1999).

The efficiency of these plant-mediated processes depends on nutrient availability in the environment and inherent functional properties of plants. However, little is known about how nutrient availability will affect these processes in forested wetlands in the tropics. In a factorial experiment we fertilized 48 dwarfed Rhizophora mangle (red mangrove) trees along tidal-elevation and water-depth gradients at Twin Cays, a range of intertidal, peat-based offshore mangrove islands in Belize, Central America. Initial results indicated that phosphorus (P) deficiency is a major factor limiting primary productivity. Phosphorus-fertilized trees had a significant decrease in P-use efficiency and P-resorption efficiency, but a significant increase in nitrogen (N)-use efficiency and N-resorption efficiency in their leaves compared with controls and N-fertilized trees. Sclerophylly decreased dramatically in P-fertilized trees, while the nutritional quality of the plant tissue increased. Phosphorus fertilization did not affect P leaching from green leaves. We found no fertilizer effect on the decomposition rates of leaf tissue, possibly due to higher phenolic concentrations in the P-fertilized trees compared with controls and N-fertilized trees. However, belowground decomposition of cotton strips increased in the substrate associated with P-fertilized trees. Environmental conditions related to position along a tidal gradient may be as important as nutrients in controlling belowground decomposition.

These watersheds have perched aquifers so all groundwater discharges as well as surface runoff were measured at V-notch weirs which included volume-integrating flow-proportional samplers. Interannual variations in annual and seasonal precipitation during this study spanned approximately the range of 160 yr weather records in the region. Annual total-N area yields from the overall watershed varied nine-fold, correlations of all N-parameter discharges with precipitation were highly significant, and power function regressions of precipitation vs N-discharge explained from 36 to 59% of the variance. Nitrogen fluxes from a cropland watershed were much higher and more variable with volume of precipitation, while fluxes from a forested watershed were much lower and were primarily composed of organic-N. Correlations of N-fluxes with precipitation were higher in the winter and spring. Annual and seasonal N-concentrations also often increased significantly with precipitation. Variations in seasonal air temperature sometimes explained significant amounts of variance in N-discharges, especially ammonium. A model composed of regressions was used to construct graphical and tabular summaries.

Smithsonian in Your Classroom. AN - 62247441; ED463221 AB - Long before he was a Founding Father, Benjamin Franklin was world famous for his work in electricity. He challenged the prevailing idea that there were two distinct kinds of electrical fluid, proposing that there is one kind of electricity and two charges. He invented the lightning rod which is still used today and so found a highly practical use for one of his scientific theories, that lightning and electricity are the same thing. But Franklin never thought of himself as a scientist, and the word did not enter the English language until some 50 years after his death in 1790. Science was not considered a profession in the 18th century, a time that saw the creation of whole new fields of science: electricity, geology, paleontology, and modern chemistry. In an exhibit that opened in 1999, the Smithsonian's National Portrait Gallery spotlighted a collection of portraits of Benjamin Franklin and his colleagues in natural philosophy, as science was then called. This issue of "Smithsonian in Your Classroom" reproduces the portraits of Edward Bromfield, David Rittenhouse, Benjamin Rush, David Wiley, and John Winthrop; presents an overview of Franklin and his activities; and provides three lesson plans highlighting these activities. Lesson 1 revolves around language arts; lesson 2 addresses the sciences; and lesson 3 features the visual arts. In each lesson plan, a student objective is given, materials needed are listed, and a classroom procedure is suggested. Additional information about Franklin is attached along with a reference list that contains five books, four books for young people, and four Web sites.

Silicate melting begins at 1000 degrees C, and Indarch is completely melted by 1500 degrees C. The metal-sulfide component melts completely at 1000 degrees C. Substantial melt migration occurs at 1300-1400 degrees C, and metal migrates out of the silicate charge at 1450 degrees C and approximately 50% silicate partial melting. As a group, our experiments contain three immiscible metallic melts (Si-, P-, and C-rich), two immiscible sulfide melts (Fe- and FeMgMnCa-rich), and silicate melt. Our partial melting experiments on the Indarch (EH4) enstatite chondrite suggest that igneous processes at low fO (sub 2) exhibit several unique features. The complete melting of sulfides at 1000 degrees C suggests that aubritic sulfides are not relics. Aubritic oldhamite may have crystallized from Ca and S complexed in the silicate melt. Significant metal-sulfide melt migration might occur at relatively low degrees of silicate partial melting. Substantial elemental exchange occurred between different melts (e.g., S between sulfide and silicate, Si between silicate and metal), a feature not observed during experiments at higher fO (sub 2) . This exchange may help explain the formation of aubrites from known enstatite chondrites.

Applications of the anatomy, mode of skeletal growth, and functional requirements basic to living species permit recognition of a few organs of these partially preserved polypides, their functions, and their relationships to enclosing skeletons. Only one basic polypide anatomy is indicated in lower Paleozoic trepostome species, in contrast to the wide diversity of polypide anatomy and their lack of correlation with skeletal characteristics in living stenolaemates. In general, the longer the evolutionary history, the greater the diversity of skeletal morphology in stenolaemates. Apparently, polypide diversity and lack of correlation with skeletal morphology also have increased over time. The complex skeletal septa in autozooecial apertures of the lower Paleozoic trepostome Hallopora have been interpreted as reflecting an organ of full-sized feeding polypides. Applications of the basic biological concepts of living species suggest that the septa provided reduced skeletal apertures to fit smaller polypides of polymorphs that secondarily occupied the living chambers of full-sized degenerated feeding polypides.

Data from 2673 localities consists of a synonomized list of 2329 species (S) and 61 369 occurrences (n). Here, the margins are divided into five geographical regions: Pacific (PA), S =965, n=19 014; Arctic (AR), S=458, n=7342; Atlantic (AT), S=878, n=10 034; Gulf of Mexico (GM), S=849, n=18 011; Caribbean (CR), S=1188, N=6968. As for many other organisms, species richness is lowest in the Arctic and highest in the Caribbean. In each region, the distribution of species richness and occurrences is a log series. Consequently, the entire series of species occurrences is predicted by the single proportionality constant, alpha . After log series rarefaction, differences in species richness among areas are nearly all accounted for by species occurring less than or equal to 10 times. Most of the differences are accounted for by species occurring once, less by twice, and so on. For example, species occurring once account for 81% of the difference in species richness between the Atlantic and Caribbean, and those occurring once and twice account for 87% of the difference. Most rare species have no fossil record and most endemic species are rare. Probably most of these species evolved recently indicating more origination in species-rich areas. High origination might also be coupled with less extinction. Although each of the five regions can easily be distinguished by differences in composition, in all regions the 10 most abundantly occurring species exhibit nearly equal proportions of occurrences. No region is dominated by only one or two species. All regions exhibit the log series distribution, have nearly equal proportions for abundant species, and differ only in the number of rare species that coexist. Thus, from the point of view of the distribution of occurrences, the most striking aspect is the similarity among regions.

Because of the magnitude of the conservation problems in the Hawaiian Islands, it is vital that biologists, conservationists, and land managers have the most up-to-date information possible. This 1999 assessment of Hawaiian vascular plant species at risk is an update of the compilation provided by Wagner et al. (1990). One of the primary reasons for publishing the 1999 list is to provide what we, the authors, feel is the most up to date possible overall assessment. Another objective for this compilation is to provide all of the other systems for Hawai`i (US, HINHP, and IUCN) side by side so that comparisons can be made directly and easily. When there are differences in ranking between the systems for a particular taxon we hope to stimulate further evaluation of that taxon so that its status can be refined.

Resemblance to these ants, which deliver painful stings, presumably reduces the likelihood that the fly will be attacked by potential predators. The incident described in this note shows that this resemblance, however, also has at least occasional negative consequences for the fly.

We first compared the results of a previous restriction fragment length polymorphism (RFLP)-based study with 1453 nucleotides from the mitochondrial cytochrome oxidase subunit I (COI), ATP-synthase 6 (ATPase 6), and ATP-synthase 8 (ATPase 8) genes. Separate phylogenetic analyses of the RFLP and sequence data provided identical and well-supported hierarchical species-level reconstructions that grouped occidentalis and townsendi as sister taxa. We then explored several general features of mitochondrial evolution via a comparison of the RFLP and sequence data sets. Qualitative rate differences that seemed evident in highly autocorrelated comparisons of RFLP vs. sequence pairwise distances were not supported when autocorrelation was removed. We also noted a high variance in corresponding RFLP and sequence distances after the removal of autocorrelation effects. This variance suggests that caution should be used when combining RFLP and sequence-based data in studies that require the large-scale synthesis of divergence estimates drawn from sources employing different molecular techniques. Finally, we used our parallel RFLP and sequence data to design and validate a rapid and inexpensive polymerase chain reaction-RFLP (PCR-RFLP) protocol for determining species-specific mitochondrial haplotypes. This PCR-RFLP technique will be applied in ongoing studies of the occidentalis/townsendi hybrid zone, where the historic and geographical complexity of the interbreeding populations necessitates the genotyping of thousands of individual warblers.

Over a three-week period, two teams of individuals trained in the HGM methodology assessed 44 riverine wetlands on the Coastal Plain of Delaware, Maryland, and Virginia, USA. Results demonstrated a high degree of agreement between the two assessment teams for both Variable Subindices and Functional Capacity Index Scores, indicating that the assessment models were robust and results were repeatable. Analyses of the data demonstrated the importance of only using variables whose measurements are repeatable. When variable measurements are not repeatable, HGM functional capacity scores are detrimentally affected, especially functions that are modeled by only a few variables.

Twenty-four of these females were found in the following year and their offspring were sampled. Using seven hypervariable microsatellite loci, we excluded the consort male as the father in 43% of the cases. The probability of exclusion of these seven loci was 98.2%. Contrary to expectations, inland females had higher rates of extraconsort fertilizations (ECFs) (70%) than beach females (23%). Younger females (<9 years) had slightly more ECFs than older females, but this was not significant. The duration of male consortship did not differ between females with ECFs and females fertilized by their consort male. Two explanations may account for the inland females having more ECFs: a higher ratio of females to tenured males inland may provide a greater opportunity for nonconsort males to obtain copulations; and inland females travel greater distances to depart for the ocean and may attract more males. These results are more consistent with the hypothesis that ECFs are a by-product for females of male strategies to maximize reproductive success than with hypotheses concerned with either material or genetic benefits gained by females.

The Bird Banding Laboratory of the US Geological Survey was founded in 1920, and now acts as a clearinghouse for all data collected on banded birds. Over 60 million birds have been banded in the past century, and 3.3 million bands have been reported, including 80,000 in the past year. Banders have developed special techniques to capture and band birds, depending upon the requirements of the species. Banding is especially important for tracking the species that are in decline, such as the painted bunting and indigo bunting.

Using discriminant function analysis on paired sites we were able to distinguish foliage-gleaning species from the Nearctic and Palaearctic with few misclassifications. The two variables that most consistently distinguished species of the two avifaunas were the percentage use of conifer foliage and the percentage use of all foliage. Nearctic foliage-gleaner assemblages had more species that foraged predominantly from coniferous foliage and displayed a greater tendency to forage from foliage, both coniferous and broad-leafed, rather than twigs, branches, or other substrates. The greater specialization on foliage and, in particular, conifer foliage by New World canopy foliage insectivores is consistent with previously proposed hypotheses regarding the role of Pleistocene vegetation history on ecological generalization of Eurasian species. Boreal forest, composed primarily of spruce and pine, was widespread in eastern North America, whereas pockets of forest were scattered in Eurasia (mostly the mountains of southern Europe and Asia). This may have affected the populations of birds directly or indirectly through reduction in the diversity and abundance of defoliating outbreak insects. Loss of habitat and resources may have selected against ecological specialization on these habitats and resources.

Suggested analogies between domes on Venus and seamounts on the northern East Pacific Rise and off Hawaii have been tested by D. K. Smith [J. Volcanol. Geotherm. Res. 73 (1996) 47-64] using comparisons of size and shape and significant differences identified. GLORIA images of flat-topped seamounts near Hawaii show them to have stellate planforms. Over half of the total population of 375 domes on Venus have been modified and many have stellate planforms. We have focused on the similarities in stellate planforms between flat-topped seamounts and modified domes on Venus. We have used GLORIA sonar and Magellan radar data to constrain the formation and evolution of both flat-topped seamounts on the ocean floor and volcanic domes on Venus to see if the processes that formed them are similar. We propose that flat-topped seamounts on the Hawaiian Ridge are built on sediments overlying the oceanic crust and that available evidence supports three processes that can form stellate margins; (1) radial dike intrusions related to flank rift zones; (2) dike intrusions which cause slope failures; and (3) gravitational slope failures unrelated to intrusions. For Venus, where low erosion rates and the absence of a sediment layer results in lavas being emplaced directly onto the crust, the available evidence supports stellate margins originating by gravitational slope failures unrelated to diking, though intrusions cannot be ruled out with existing data.

We used V-notch weirs and automated storm samplers to measure discharges and collect samples at flow intervals during 76 storms. The watershed aquifers are perched on an impervious clay layer slightly above sea level, so that combined groundwater and surface water discharges were measured at the weirs. The concentrations of particulate forms of organic N (PON), organic P (POP), and inorganic P (PPi) increased up to 3 orders of magnitude during storm events and usually peaked prior to the peak water discharge, while concentrations of dissolved forms of organic N (DON), organic P (DOP), inorganic P (DPi), and nitrate did not change very much. Dissolved and particulate ammonium (DNH4 and PNH4, respectively) concentrations increased up to fivefold in storm events but remained low compared to other N forms. The watershed with the most cropland discharged the highest concentrations of total N, PON, DNH4, nitrate, POP, and PPi. A forested watershed discharged the highest concentrations of DON, PNH4, and DOP. The watershed with the most grazed land discharged the highest concentration of DPi. PON and POP were the dominant forms of N and P in storm discharges from all watersheds. Concentrations of nitrogen were higher in spring and summer storms than in winter storms, but phosphorus concentrations were much higher in the summer storms than in spring or winter. The concentrations of PPi, POP, PON, DNH4, and PNH4 increased significantly with peak water discharge among storms, while concentrations of DPi, DOP, DON, and nitrate were not correlated with peak discharge. The ratios of TN/TP and TIN/TIP declined significantly with peak water discharge among storms.

We mapped the present distribution of thamin using ground surveys and tied this information to habitat types derived from satellite images in order to detect patterns that might indicate the landscape features which precipitated the decline. We conducted a survey of 24 out of 28 Myanmar townships that were reported to contain thamin in 1992, and evidence of thamin were found in 23 of these townships, predominately in mixed deciduous forests where dipterocarp trees were present. There was no significant correlation between the number of thamin detected and forest remaining in the township, or the size of the human or livestock population. A landcover classification of Landsat Thematic Mapper images indicated 58% of the study area contained deciduous forest, of which 12% was dipterocarp forest. Forest tracts containing thamin were digitized and landscape analyses were conducted on a resampled habitat map that emphasized dry and dipterocarp deciduous forest. Of six landscape variables measured only core area size was a significant predictor for the presence of thamin. None of the unsurveyed indaing forest tracts possessed a core area large enough to support thamin. The pattern of thamin decline matches predictions that peripheral, rather than central, populations are more likely to persist in declining species.

Free-living insect herbivores foraging on 10 000 tagged seedlings representing five species of common rainforest trees were surveyed monthly for more than 1 year in an unlogged forest plot of 1 km super(2) in Guyana. 2. Overall, 9056 insect specimens were collected. Most were sap-sucking insects, which represented at least 244 species belonging to 25 families. Leaf-chewing insects included at least 101 species belonging to 16 families. Herbivore densities were among the lowest densities reported in tropical rainforests to date: 2.4 individuals per square metre of foliage. 3. Insect host specificity was assessed by calculating Lloyd's index of patchiness from distributional records and considering feeding records in captivity and in situ. Generalists represented 84 and 78% of sap-sucking species and individuals, and 75 and 42% of leaf-chewing species and individuals. In particular, several species of polyphagous xylem-feeding Cicadellinae were strikingly abundant on all hosts. 4. The high incidence of generalist insects suggests that the Janzen-Connell model, explaining rates of attack on seedlings as a density-dependent process resulting from contagion of specialist insects from parent trees, is unlikely to be valid in this study system. 5. Given the rarity of flushing events for the seedlings during the study period, the low insect densities, and the high proportion of generalists, the data also suggest that seedlings may represent a poor resource for free-living insect herbivores in rainforests.

The collection included 13 193 individuals representing 349 species of leaf-chewing insects and 44 900 individuals representing 430 species of sap-sucking insects. Despite a high sampling intensity, the species accumulation curve did not reach an asymptote. This pattern was attributed to the highly aggregated distribution of insects on individual host trees. The number of insect species collected on a particular Ficus species ranged from 34 to 129 for leaf-chewing and from 51 to 219 for sap-sucking insects. Two Ficus species growing on the seashore sustained less speciose insect communities than their counterparts growing in forest. For the forest figs, significant predictors of insect species richness included leaf palatability and leaf production for leaf-chewing insects (40% of the variance explained), and tree density and leaf expansion for sap-sucking insects (75%). The high faunal overlap among Ficus communities and the importance of local resources for insect herbivores suggest that highly specialized interactions between insect herbivores and Ficus in Papua New Guinea have not been conserved in evolutionary time. This is at variance with the dogma of old, extremely specialized and conservative interactions between insect herbivores and their hosts, providing numerous ecological niches in the floristically rich tropics.

AN - 69840951; 10377041 AB - Freeze-thawing cat sperm in cryoprotectant results in extensive membrane damage. To determine whether cooling alone influences sperm structure and viability, we compared the effect of cooling rate on sperm from normospermic (N; > 60% normal sperm per ejaculate) and teratospermic (T; 0.05) immediately after exposure to low temperatures and after warming to 25 degrees C. However, the proportion of spermatozoa with intact acrosomes declined (p 0.05) a high proportion of spermatozoa with intact acrosomes (N, 75.5%; T, 68.3%), which also remained similar (p > 0.05) between cat populations (N, 64.7%; T, 56.8%) through continued cooling to 0 degrees C. Results demonstrate that 1) rapid cooling of domestic cat sperm induces significant acrosomal damage without altering sperm motility, 2) spermatozoa from teratospermic males are more susceptible to cold-induced acrosomal damage than normospermic counterparts, and 3) reducing the rate of initial cooling markedly decreases sperm structural damage.

Reproductive techniques (high- and low-tech) find their greatest application in understanding species uniqueness, adaptations and physiological mechanisms, not in the large-scale `assisted breeding' and the production of offspring. Models of how to use these tools to study reproductive fitness are emerging to help `insure' gene diversity and even propagate endangered species, but only after fundamental databases have been developed. Examples are provided of how non-invasive hormone metabolite monitoring, artificial insemination and genome resource banking are being used ex situ and in situ to understand wildlife biology. We predict that as the fundamental, multi-species database grows, so will the applied benefits for: (1) developing genome banks for insuring extant genetic diversity; (2) assessing the relationship of physiology, behaviour and environmental perturbations; (3) managing small populations; and (4) dealing with dilemmas ranging from contraception to skewed sex ratios to animal welfare. Most progress will be made in using these tools in systematic studies to solve the mystery of how thousands of unstudied species reproduce. Carried out appropriately, financial costs will be consistent with any approach for generating sound scientific knowledge.

Siphonalean green algae often dominate the standing stocks and productivity of Caribbean mangrove island environs and are also abundant in virtually all calm-water reef habitats. The experimental organism Avrainvillea longicaulis is particularly abundant in the study sites west of Carrie Bow Cay and Curlew Cay, Belize. The recycling of protoplasm out of older epiphytically impaired blades of A. longicaulis, and simultaneous formation of apical siphon extensions elsewhere, leads to rapid proliferation of new blades--hypothetically, at relatively low energy cost to the plant. The rapidity of siphon extension occurs at least an order of magnitude faster than that possible by photosynthetic production alone, resulting in fully formed proliferations within 3 d. At the same time, the older epiphytized blades become empty, first at the tips, then progressively toward the holdfast, appearing translucent-brown and flaccid within 3 d, followed by senescence. We hypothesize that A. longicaulis rapidly responds to epiphyte colonization/impairment by reallocating protoplasm for new growth through protoplasmic streaming. The alternative hypothesis, that the herbivorous crab Thersandrus compressus might beneficially control epiphytes on A. longicaulis, was falsified by its strong negative effects (i.e., decreased growth and increased host mortality). The hypothesis that allelopathic secondary chemicals may play an antifouling role also was not supported by our experiments; i.e., the consistently vigorous growth rates of the five dominant epiphyte species attached to A. longicaulis were not significantly less than populations of the same species attached to carbonate rock. All of the manipulative results (i.e., experimental induction of blade abandonment followed by new proliferation), as well as the populational survey findings (i.e., greater proliferation by epiphytized plants) and physiological data (i.e., photosynthetic inhibition by epiphytes), support the blade abandonment/proliferation hypothesis, thereby documenting an effective epiphyte-control strategy.

Observations of BCI mammals have been compiled for 49 years. Frugivorous mammals experienced famine between September and January in 1931-1932, 1958-1959, 1970-1971, and 1993-1994. The most recent famine is evident from an 11-yr record of natural deaths of mammals and a 2-yr record of population densities. Famine occurred every time a mild dry season followed an El Nino event in the 49-yr record. This coincidence is statistically improbable, as demonstrated by a randomization test. A 2-yr cycle of high, then low community-level fruit production has been observed twice for BCI when a mild dry season followed an El Nino event. We used 260 litter traps to monitor community- and species-level fruit production from 1 January 1987 through 30 June 1996. Community-level fruit production was greatest during the 1992 El Nino event and lowest one year later, after the mild 1993 dry season. We also reinterpret an earlier 2-yr record of fruit production in light of our 9.5-yr record of fruit production. Community-level fruit production was elevated during the 1969 El Nino event and was very low one year later, after the mild 1970 dry season. We hypothesize that (1) El Nino conditions enhance fruit production; (2) high fruit production consumes stored reserves, limiting the next reproductive event; and (3) mild dry seasons reduce fruit production. Each plant species may respond to any combination of the three components of this hypothesis. Community-level fruit production is extremely low when species sensitive to components 1 and 2 are entrained with species sensitive to component 3, or when a mild dry season follows one year after an El Nino event. El Nino events bring dry, sunny conditions to BCI and a large portion of the wet tropics. Drought and sun may both favor fruit production in wet tropical forests. Drought is known to synchronize flowering, and sunny conditions may relieve light limitation. The El Nino Southern Oscillation has a strong 24-mo periodicity. This creates a strong tendency for dry, sunny years to alternate with wet, cloudy years in Central America and elsewhere in the tropics. We present evidence that this alternately enhances and reduces fruit production on BCI. Terborgh hypothesized that predators regulate frugivorous mammals in tropical forests. As a corollary, he further hypothesized that famines occur on BCI because several large predators are absent and frugivores escape predation. We extended censuses to the nearby mainland to evaluate this hypothesis. Poachers, who are active on the mainland, reduce the abundances of game species below levels maintained in the presence of large felids and raptors. There was evidence for famine in poached, mainland populations, and we rejected the hypothesis that reduced predation pressure is a prerequisite for famine.

The mussel often forms dense mats that can increase infaunal density and species richness. This research experimentally examines the relationship between the physical structure of the mussel mat habitat and the biological activities of the mussel as it relates to the macrofaunal assemblages in Mission Bay, San Diego, California, USA. The results of this experiment demonstrate that the effects of physical structure consistently outweigh the effects of living mussels. Total macrofaunal densities, species richness, and densities of a variety of taxa (e.g. the snail Barleeia subtenuis Carpenter, nemerteans, and amphipods) were enhanced by the presence of the artificial mats. The tube-building, planktonically-developing polychaete, Pseudopolydora paucibranchiata Okuda, however, was apparently inhibited by mats, as were planktonic developers as a group. The effects of structure provided by mussel shells themselves appeared to be weaker than the mat effects, although some taxa, such as the gastropod B. subtenuis, responded to shells alone. The influences of living mussels also were less pronounced than that of artificial mats, although non-planktonic developers, including midge larvae and the tanaid Leptochelia dubia Kroger, showed positive responses to live mussels. In general, these results are consistent with observed effects of other habitat-creating exotics, and suggest that facilitation of biota by non-native species capable of creating physical complexity in ecosystems may be a major and predictable consequence of biological invasions.

Logging has been a long pasttime in these forests; the environmental movement of the 1970s-1980s brought opposition, as environmentalists recognized the importance of preserving sensitive areas. While much of the logging was halted by a coalition of environmental groups, the growing conflict between environmentalists and loggers spilled over into the community. The QLG was founded in 1992 to provide a roundtable for stakeholders. As common ground was found, the participants developed a Community Stability Proposal identifying acceptable logging compromises. This process ultimately lead to the passage of a federal pilot project allowing selective logging and protection of sensitive areas on public lands.

Both allozyme and mtDNA evidence indicate that this highly endemic fauna is non-monophyletic. Species from the upper Amargosa basin comprise a clade most closely related to snails living in the Colorado basin. Snails from the lower Amargosa basin (Death Valley trough) reflect a complex evolutionary history and two of these species are more closely related to an estuarine species from western California than to other snails of the region. These results indicate a commonality of pattern with the well-studied Death Valley pupfishes (Cyprinodon), which also are non-monophyletic and include species that are most closely related to Colorado basin congeners. These biogeographic patterns are interpreted within the context of a recently proposed model for the early history of the lower Colorado River.

Ecological changes through time in habitat utilization by living organisms also can blur distinctions between faunas or floras associated with particular habitats. If taphonomic processes affect habitat specificity in bone assemblages, then this should be revealed in time sequences of remains from particular habitats. We analyzed Recent surface bone in six habitats of Amboseli National Park, Kenya, to determine whether taxonomic composition varied with the degree of taphonomic alteration (as indicated by bone weathering stage). The dataset consisted of 1362 separate bone occurrences classified according to their state of weathering. These bone occurrences represented 27 mammalian taxa from bush, openwood, densewood, lakebed, plains, and swamp habitats. The distinctiveness of the bone assemblages was measured by the quantified Dice coefficient, which accounts for both the presence or absence of taxa and their relative proportions. The differences among the weathering stage subsamples were compared with known environmental changes at Amboseli over the estimated time period of bone accumulation (15-25 years). Habitat distinctiveness based on the bone assemblages was lower in subsets with higher weathering stages, although not all habitats showed this to the same degree, and open habitats (e.g., plains, lakebed) generally remained distinct from closed habitats (densewood, bush). The greatest change in the similarity among habitats occurred between weathering stages 2 and 3, which corresponds to deaths between 1969 and 1973, a period of woodland retreat and expansion of open habitats in the park. We attribute the loss of environmental resolution in the weathered bone subsamples primarily to time-averaging and the shifting of habitat boundaries. The time period represented by these bone assemblages is small compared to the time-averaged paleosol or land surface assemblages in the fossil record, suggesting that ecological fluctuations can compromise interpretations of habitat heterogeneity in fossil assemblages. Our study indicates that it is probably the magnitude of ecological changes rather than time per se that limits resolution. If distinct paleohabitats can be supported based on time-averaged fossil evidence, however, this implies that ecological fluctuations were not sufficient to homogenize these distinctions over the period of time-averaging.

Our aim was to determine whether compensatory photosynthesis and growth would be altered by increasing concentrations of atmospheric CO sub(2). Defoliation of developing leaflets on seedlings of a tropical tree, Copaifera aromatica, caused increases in photosynthesis under ambient CO sub(2), but not under elevated CO sub(2). An enhancement in the development of buds in the leaf axils followed defoliation at ambient levels of CO sub(2). In contrast, under elevated CO sub(2), enhanced development of buds occurred in undefoliated plants with no further enhancement in bud development due to exposure to elevated CO sub(2). Growth of leaf area after defoliation was increased, particularly under elevated CO sub(2). Despite this increase, defoliated plants grown under elevated CO sub(2) were further from compensating for tissue lost during defoliation after 5 one half weeks than those grown under ambient CO sub(2) concentrations.

Before the early 1990s, the species occurred in Panama primarily as a vagrant. Apple snails were introduced to Lake Gatun in central Panama in the late 1980s, and by 1994 Snail Kites had colonized the lake from population sources at least 350 km away and initiated breeding. Since 1994 the population has increased rapidly and the species can now be found throughout the lake.

Declines of approximately 90% are indicated for three recent decades from the Breeding Bird Survey, Christmas Bird Counts, and Quebec Checklist Program. Analyses of abundance classifications in bird distribution books and annotated checklists reveal an overlooked but long-term decline dating back to at least the early part of this century. Rusty Blackbirds were described as very common to abundant in 56% of the pre-1920 published accounts, 19% of the 1921-1950 accounts, and only 7% of the post-1950 accounts. Rusty Blackbirds were described as uncommon in none of the pre-1950 accounts, 18% of the 1951-1980 accounts, and 43% of the post-1980 accounts. A similar pattern was found for analyses based on local checklists. Destruction of wooded wetlands on wintering grounds, acid precipitation, and the conversion of boreal forest wetlands could have contributed to these declines. Systematic analysis of regional guides and checklists provides a valuable tool for examining large-scale and long-term population changes in birds.

In this study, avian communities were surveyed in 11 habitat types in central Panama, across a gradient from extensive forest to intensive agricultural land uses, to examine patterns of species richness and abundance and community composition. Wooded habitats, including extensive and fragmented forests, shade coffee plantations, and residential areas supported the most species and individuals. Nearctic-Neotropical migratory species were most numerous in lowland forest fragments, shade coffee, and residential areas. Introduced Pinus caribbea and sugar cane plantations supported the fewest species compared to all other habitats. Cattle pastures left fallow for less than two years supported more than twice as many total species as actively grazed pastures, such that species richness in fallow pastures was similar to that found in wooded habitats. Community similarities were relatively low among all habitat types (none exceeding the observed 65% similarity between extensive and fragmented lowland forests), but communities in shade coffee and residential areas were 43% and 54% similar to lowland forest fragments, respectively. Fallow pastures and residential areas shared 60% of their species. Bird communities in shade coffee and residential areas were characterized by higher proportions of frugivorous and nectarivorous species than in native forests. These same guilds also were better represented in fallow than in grazed pastures. Raptors and piscivorous species were most prevalent in cattle pastures and rice fields. These results, though based upon only species richness and abundance, demonstrate that many human-altered habitats have potential ecological value for birds, and conservation efforts in tropical areas should focus greater attention on enhancement of agricultural and developed lands as wildlife habitat. To understand the true conservation value of these modified lands will require examination not only of numbers but also of the types of species supported by these habitats, their reproductive output and survival rates.

The effects of fish grazing on epiphytes, and likely enhancing T. testudinum growth, was tested through an exclusion experiment. Twelve (2 x 2m) independent experimental plots were selected within a shallow monospecific bed to which three randomized treatments (exclusion fences, open fences and controls) with four replicates each were assigned. The epiphyte load was monitored on T. testudinum leaves inside the plots from January 1995 to March 1996. Treatment effects occurred during a chlorophyte bloom in March 1995, when the epiphyte biomass was significantly higher inside the exclusion cages than in either of the controls. The composition of the epiphytic community in March 1995 was dominated by sheet-like Enteromorpha and filamentous algae such as Cladophora , which are less resistant to herbivory than the coarsely-branched forms of red algae (e.g. Hypnea , Chondria and Acanthophora) that bloomed subsequently. These results suggest that herbivory change seasonally depending on the availability of different prey species to fish-grazers, which preferentially utilize the fleshy green algae typical of bloom conditions over the thicker coarsely-branched red algae. In the nutrient-rich lagoon the role of top-down interactions in enhancing T. testudinum growth is limited to the reduction of shading by green macroalgae.

Their commitment to this scale of farming and marketing reflects the growing trend toward small farms and farmers' markets, and the appreciation with which they are received in urban settings. An estimated $1.1 billion is spent annually in 2600 markets, an increase of 50% in five years. Shoppers benefit not only from fresh and diverse produce, but also from the social experience of farm market shopping. While California was the site of the farmers' market Renasissance, the most famous market is the New York City Greenmarket, in which 200 farmers sell to 150,000 customers weekly at sites throughout the city. Many cities have begun to institutionalize these markets, giving them physical structures.

Microspheres added to natural plankton assemblages at a concentration of 5 x 10 super(6) to 10 super(7) ml super(-1) were rapidly ingested by a variety of planktonic organisms including small flagellates, ciliates, dinoflagellates, ebriids and amoebae. Prey thus labeled were in turn phagocytized by C. furca and were easily detected within the predator using fluorescent microscopy. Ingestion rates were calculated by following the appearance of labeled food vacuoles in C. furca over time. C. furca did not ingest microspheres directly, and thus the calculated rates represented feeding on labeled prey only. Food vacuole contents and labeled prey were identified using a modified Protargol staining procedure that retained the integrity and fluorescent properties of the latex microspheres. Data on food vacuole content and potential prey availability indicated that C. furca preyed mainly on choreotrich ciliates (i.e. Strobilidium spp. and tintinnids) 10 to 40 mu m in diameter. In addition, feeding rates were strongly correlated with choreotrich densities and suggested that C. furca preferred ciliates of the genus Strobilidium. Ingestion rates of C. furca ranged from 0 to 0.11 prey h super(-1), and varied greatly from one year to the next. Clearance rates ranged from 0 to 12.49 mu l (C. furca) super(-1) h super(-1), with an average of 2.1 plus or minus 0.41 ml (C. furca) super(-1) h super(-1). Both ingestion and clearance rates were comparable to rates previously reported for mixotrophic and heterotrophic dinoflagellates. The method presented here has several advantages for the study of mixotrophy in large, slow-feeding dinoflagellates. Live prey found in natural water samples are used, and surface characteristics of prey remain unaltered. No addition of prey is necessary, and only a minimum amount of handling of the sample is required. Incubation experiments can last for 6 h, allowing sufficient time for the appearance of labeled food vacuoles in predators with low feeding rates.

AN - 69731347; 10228963 AB - Phosphorus is an essential element for all life forms. It is a mineral nutrient. Orthophosphate is the only form of P that autotrophs can assimilate. Extracellular enzymes hydrolyze organic forms of P to phosphate. Eutrophication is the over-enrichment of surface waters with mineral nutrients. The results are excessive production of autotrophs, especially algae and cyanobacteria. This high productivity leads to high bacterial populations and high respiration rates, leading to hypoxia or anoxia in poorly mixed bottom waters and at night in surface waters during calm, warm conditions. Low dissolved oxygen causes the loss of aquatic animals and the release of many materials normally bound to bottom sediments, including various forms of P. This release of P reinforces the eutrophication. Excessive concentrations of P is the most common cause of eutrophication in freshwater lakes, reservoirs, streams, and in the headwaters of estuarine systems. In the ocean, N is believed to usually be the key mineral nutrient controlling primary production. Estuaries and continental shelf waters are a transition zone, in which excessive P and N create problems. It is best to measure and regulate total P inputs to whole aquatic ecosystems, but for an easy assay it is best to measure total P concentrations, including particulate P, in surface waters or N:P atomic ratios in phytoplankton.

Despite the extra labor required, we identify several clear advantages of the dissection method, including: (1) it provides a means of obtaining size-dependent changes in isotopic signatures that are unequivocally ontogenetic, whereas isotopic variation observed from sieve-separated size fractions could be ontogenetic or ecotypic; (2) the taxonomic identity of smaller sized specimens using the dissection method is unequivocal, whereas species identification is increasingly ambiguous in smaller size fractions using the sieve method; (3) it reveals a greater total range and a greater complexity in the pattern of ontogenetic change in stable isotopic values, whereas the sieve method averages the isotopic signal across the entire ontogenetic range preserved within the whole tests that are used. Our results from serial dissections demonstrate that among the species analyzed, R. fructicosa and P. acervulinoides yield relatively negative adult delta (super 18) O values, a large size-related change in delta (super 13) C values (1.32 and 2.05 per mil, respectively), and virtually no correlation between size-related delta (super 13) C and delta (super 18) O values. On this basis we suggest that these were photosymbiotic species that inhabited relatively shallow surface waters. Evidence for photosymbiosis is not as compelling for P. palpebra, as this species yields a 1.06 per mil shift in delta (super 13) C and relatively negative delta (super 18) O values in adult chambers, but much stronger correlation between size-related delta (super 13) C and delta (super 18) O values (r (super 2) = 0.40) than in R. fructicosa and P. acervulinoides. Planoglobulina multicamerata yields the most positive adult delta (super 18) O values of the species studied, a strong covariance between size-related delta (super 13) C and delta (super 18) O values (r (super 2) = 0.77), and a 0.97 per mil shift in delta (super 13) C composition during ontogeny. We conclude that this species lacked photosymbionts and migrated to a deeper surface water paleohabitat as it increased in size. Single specimen analyses of tightly constrained size fractions reveal a high degree of intraspecific variation. delta (super 13) C and delta (super 18) O values vary by up to 0.70 and 0.28 per mil in R. fructicosa, 1.41 and 0.80 per mil in P. acervulinoides, 0.66 and 0.82 per mil in P. palpebra, and 0.18 and 0.33 per mil in P. multicamerata, respectively. Such a range of isotopic variation has been observed in modern day planktic foraminifer assemblages, and likely results from growth of individuals during different phases of the seasonal cycle and/or the kinetic effect of intraspecific variation in shell calcification rates. As suggested by other investigators, large sample sizes should be analyzed to provide the most reliable correlation of stable isotopic stratigraphic records.

The spherulitic layer contains abundant rock fragments (chalk, limestone, dolomite, chert, mica books, and schist) as well as shocked quartz, abundant large Cretaceous planktic foraminifera, and rounded clasts of clay as long as 4 mm interpreted as altered tektite glass probably derived from the Chicxulub impact structure. Most of the Cretaceous foraminifera present above the spherule layer are not survivors since small specimens are conspicuously rare compared to large individuals. Instead, the Cretaceous taxa in Paleocene sediments are thought to be reworked. The first Paleocene planktic foraminifera and calcareous nannofossil species are recorded immediately above the spherule bed, the upper part of which contains an iridium anomaly. Hence, deposition of the impact ejecta exactly coincided with the biostratigraphic K-T boundary and demonstrates that the impact event was synchronous with the evolutionary turnover in the oceans. These results are consistent with a reanalysis of the biostratigraphy of the K-T boundary stratotype, which argues that shallow-marine K-T boundary sections are not biostratigraphically more complete than deep-sea K-T boundary sites.

Our conclusion is that the depositional histories of the U.S. Gulf of Mexico-Atlantic coastal plain and the North Sea basin show many similarities, on a variety of time scales, over the interval 60-46 Ma. Considering the tectonic imprint of the northeast Atlantic opening on the North Sea basin sea-level record for part of this time, it must give some weight to the claim that eustasy is the dominant mechanism controlling deposition on passive continental margins.

Here, we evaluated available data on the role of NIS in marine and estuarine communities and their interactions with other anthropogenic stressors, using an intensive analysis of the Chesapeake Bay region as a case study. First, we reviewed the reported ecological impacts of 196 species that occur in tidal waters of the bay, including species that are known invaders as well as some that are cryptogenic (i.e., of uncertain origin). Second, we compared the impacts reported in and out of the bay region for the same 54 species of plants and fish from this group that regularly occur in the regionA's tidal waters. Third, we assessed the evidence for interaction in the distribution or performance of these 54 plant and fish species within the bay and other stressors. Of the 196 known and possible NIS, 39 (20%) were thought to have some significant impact on a resident population, community, habitat, or process within the bay region. However, quantitative data on impacts were found for only 12 of the 39, representing 31% of this group and 6% of all 196 species surveyed. The patterns of reported impacts in the bay for plants and fish were nearly identical: 29% were reported to have significant impacts, but quantitative impact data existed for only 7% (4/54) of these species. In contrast, 74% of the same species were reported to have significant impacts outside of the bay, and some quantitative impact data were found for 44% (24 /54) of them. Although it appears that 20% of the plant and fish species in our analysis may have significant impacts in the bay region based upon impacts measured elsewhere, we suggest that studies outside the region cannot reliably predict such impacts. We surmise that quantitative impact measures for individual bays or estuaries generally exist for <5% of the NIS present, and many of these measures are not particularly informative. Despite the increasing knowledge of marine invasions at many sites, it is evident that we understand little about the full extent and variety of the impacts they create singly and cumulatively. Given the multiple anthropogenic stressors that overlap with NIS in estuaries, we predict NIS-stressor interactions play an important role in the pattern and impact of invasions.

First, because of the extreme numerical dominance and breadth of habitat use of the Chaffinch (Fringilla coelebs), the European Russian sites stand as outliers to the relationships between the number of species and the abundance of all foliage-gleaning birds, as well as to more detailed patterns of the composition of the foliage-gleaner guild. The Chaffinch is one of the few canopy foliage-gleaning birds in temperate forests that is abundant in agricultural habitats during the nonbreeding season, which probably allowed a rapid expansion of its range and growth in abundance with the advent of farming in Europe. The second pattern emerges when the European Russian sites are excluded from analyses: the proportional abundance and number of species of warblers or warbler-like birds were positively related to overall abundance of foliage gleaners. This suggests that warblers prosper when there is high resource productivity during the breeding season. A possible resolution between the patterns found in European Russia and the other boreal forest sites may be that Fringilla are functionally equivalent to warblers and have essentially replaced warblers to achieve their high abundance. The patterns of relative abundance give support to both the Resource Seasonality Hypothesis (warblers versus tits), and the Ecological Replacement Hypothesis (Fringilla versus warblers) as explanations for shifts in the numerical dominance of different types of foliage gleaners in different regions.

We examined the dynamics of reproduction of the pelagic-spawning fish Thalassoma bifasciatum from that perspective at San Blas, Caribbean Panama. During April-June 1993, similar to 75% of females spawned each day, with mean output per female per day at about one-third the potential maximum. Output peaked several days before the new and full moon, when tides were high during the afternoon spawning period. Daily fluctuations in output were weakly correlated with light (+), swell (-), and onshore wind (-) on preceding days. Settler production (determined from otolith back calculations of settlers' fertilization dates) peaked during the wet season (May-November), when winds were light and variable, spawning-period tidal heights were moderate to low, and tidal flows were off-reef at night. These conditions correspond to when most settlement occurs. Settler production was minimal during the dry season (January-March), when onshore trade winds were strong and consistent, and tidal conditions were the reverse of those in the wet season. Settlement usually occurred in one variably timed pulse per lunar cycle, around the new moon. Variation in monthly settlement strength over 11 yr (1986-1996) was unrelated to onshore wind stress during either settler arrival or settler production. The daily dynamics of settlement were unrelated to the concurrent dynamics of wind or tides, or wind dynamics up to a week before settlement. Settler production was much less continuous than spawning. Wet season settler-production dynamics were unrelated to tidal dynamics, but (weakly) negatively related to onshore wind stress. Although the dynamics of settler production and settlement were similar, bouts of settler production were about twice as long as bouts of settlement. The average lunar patterns of settler production and observed spawning were similar (weakly bimodal). Settlers produced during different lunar phases differed in the length and variability of their pelagic larval durations (PLDs). Fish with different PLDs all tended to settle around the new moon. Weakly semilunar spawning may reflect effects of weak tidal influences on egg survivorship, or of environmental constraints on adults' spawning capacity that also limit spawning to well below the potential maximum. Dry season trade winds may produce the seasonal low of settlement by depressing spawning or forcing the onshore transport of eggs and larvae. If settlement is transport-dependent, weak variable winds may have little effect on currents during the wet season, or local geography may limit such effects; tidal dynamics may not affect wet-season settlement dynamics because small (<0.6 m) tides produce weak flows. Alternatively, settlement may not be dependent on transport mechanisms. Short-term settlement dynamics result from both the dynamics of larval survival (as most larvae have near-mean PLDs) and larvae delaying or advancing settlement to settle around the new moon. Larvae spawned at different lunar phases have different patterns of variation in their PLDs but achieve similar relative settlement success. Larvae with extended PLDs may not suffer low settlement success because the inevitable age-dependent decline in survival has smaller effects on relative settlement success than does large monthly variation in the survivorship of fish spawned during different lunar phases.

In this study we examine cotyledonary resource use of the tropical tree Gustavia superba, and test whether tolerance to damage of either seeds or establishing seedlings might be an important function leading to, or maintaining, its large (> 5 g) seed reserves. We found that seeds of Gustavia were both tolerant of insect infestation and were also capable of successful germination after removal of half of their cotyledonary reserves. Simulated complete above-ground herbivory resulted in repeated resprouting (up to 8 times). Resprout shoots were constructed of a small, but fixed proportion of remaining cotyledonary mass regardless of seed size. In the absence of damage, cotyledon reserves were used for onward seedling growth; however, conversion of cotyledon resources was slow, lasting several months. Given high rates of damage to Gustavia seeds and seedlings in the field, and the apparent use of cotyledonary reserves to tolerate or recover from it in growing house experiments, we conclude that cotyledonary seed size and morphology in this species is adaptive in surviving pre- and early post-germination hazards.

Unlike multilocus DNA fingerprints (Danforth & Freeman-Gallant 1996; McRae 1996), for any given locus, bands can accurately be assigned as either paternal and maternal when at least one parent is known. Thus, even an offspring that is the product of an incestuous mating, such as between mother and son, can be identified as such when for a given autosomal locus the offspring matches two alleles from its mother (the dominant female) and none from the dominant male. Paternity can confidently be assigned to the dominant male when the offspring's paternal allele is matched only with the dominant male's genotype and not that of the helper son. To ensure paternity exclusion of the father or son by at least one locus requires about seven loci, each with six alleles to achieve theoretically an exclusion in 99% of cases. We cloned microsatellite loci to look at genetic relationships within cooperatively breeding white-browed sparrow weaver social groups.

We have previously shown that males clustered around a female wave in close synchrony. Females may have a preference for leading signals and synchronised waving may arise as an epiphenomenon of competition between males to signal first. Indeed, the males in clusters that females approach and visit in their burrows are more likely to produce leading waves than are their neighbours. Here we document two other differences in the waving behaviour of visited males and their neighbours. First, visited males complete the downward component of the wave more rapidly than their neighbours. Second, the interval between the end of one wave and the start of the next is shorter for visited males. How can waving be synchronous if visited males wave faster than their neighbours? While only 9% (40/431) of waves by neighbours did not overlap those of the visited male, 22% (110/501) of visited male waves did not overlap the wave of a focal neighbour (111 visited male-neighbour dyads). Hence, while overlapping waves are nearly synchronous, visited males produce additional, `nonoverlapping' waves that result in a higher wave rate than that of their neighbours.

Survival of larvae with intact shields was higher in the field than for larvae with shields removed. In the laboratory, E. nigrosignata feculae had a deterrent effect on feeding in the ant Myrmica rubra as did an extract of the host plant, Cordia curassavica. Three chemical types were identified in the host-plant foliage and were named beta -terpinene, alpha -pinene, and sabinene, depending on their mono- and sesquiterpene composition. This is the first report of lower terpenes (essential oils) in foliage of Cordia. Fecal shields of E. nigrosignata displayed the same terpene pattern as larval host-plant leaves. The absolute concentration of mono- and sesquiterpenes in the dorsal fecal shield depended on the plant chemical type and tended to decrease with larval age. No oxidation or detoxification products of ingested terpenes were detected in the larval fecula, indicating that the chemical composition of the larval fecal shield is influenced primarily by the host-plant secondary chemistry.

Although it is thought at present to involve only two symbionts, associated with each other in near isolation from other organisms, the fungal garderns of attine ants are in fact host to a specialized and virulent parasitic fungus of the genus Escovopsis (Ascomycotina). Because the ants and their fungi are mutually dependent, the maintenance of stable fungal monocultures in the presence of weeds or parasites is critical to the survival of both organisms. Here we describe a new, third mutualist in this symbiosis, a filamentous bacterium (actinomycete) of the genus Streptomyces that produces antibiotics specifically targeted to suppress the growth of the specialized garden-parasite Escovopsis. This third mutualist is associated with all species of fungus-growing ants studied, is carried upon regions of the ants' cuticle that are genus specific, is transmitted vertically (from parent to offspring colonies), and has the capacity to promote the growth of the fungal mutualist, indicating that the association of Streptomyces with attine ants is both highly evolved and of ancient origin.

The results are consistent with a number of features previously observed through local geodetic studies and very sparse space geodetic studies, including a dominant pattern of right-lateral shear associated with the San Andreas fault, rates of the westernmost sites (along the California coast) of 46-48 mm/yr relative to a North America reference frame, and some 11-13 mm/yr of deformation accommodated east of the Sierra Nevada in the Basin and Range province north of lat 36 degrees N. South of 36 degrees N, the solution also shows that the southernmost San Andreas fault system accommodates effectively all interplate motion and that the southern Basin and Range is not deforming significantly. At lat 37 degrees N, the eastern California shear zone appears to exhibit simple shear oriented between approximately N20 degrees W and approximately N40 degrees W relative to North America, with a fairly well defined transition zone from localized shear to diffuse spreading in the Basin and Range. Enigmatically, this transition involves a significant component of contraction normal to the overall shear-zone trend; sites in the Great Basin move southwestward at up to approximately 5 mm/yr toward sites within the eastern California shear zone. To the north, in contrast, there appears to be a relatively smooth transition from east-west spreading within the eastern Great Basin to northwest-southeast shear across the westernmost Basin and Range.

Part 2 describes the pollen of 30 genera assigned to tribes Agrostistachydeae, Chrozophoreae, Caryodendreae, Bernardieae and Pycnocomeae. In Agrostistachydeae, members of Agrostistachys and Pseudagrostistachys have similar but unspecialized pollen; grains of Cyttaranthus have weakly suprareticulate tecta of widely varying thickness and small densely spaced columellae; pollen of Chondrostylis has a croton sculpture and precisely defined bridges of ectexine over the endoaperture. Of the 11 genera assigned to tribe Chrozophoreae, pollen of Caperonia has prominent opercula, thick exines and punctate tecta, pollen of Ditaxis and Argythamnia is colpate, has large columellae, and the unevenly thick and complete tecta associated with suprareticulate sculpture or derivations thereof, and pollen of Chiropetalum has operculate apertures, diminutive columellae, and an incomplete finely reticulate tectum, characteristics which argue against a supposedly close relationship to Ditaxis and Argythamnia. Three of the four genera assigned to subtribe Doryxylinae, Doryxylon, Sumbaviopsis, and Melanolepis have similar pollen--thin exines with irregular foot layers, and irregular short columellae, whereas pollen of the fourth genus, Thyrsanthera, has thicker exines with a well-defined foot layer and more elongate columellae. The eight examined species of Chrozophora have 6-9 aperturate pollen and robust exines; two species have punctate tecta and zonorate endoapertures; the remaining species have heterobrochate tecta and lolongate endoapertures. The three genera comprising Caryodendreae, Caryodendron, Discoglypremna and Alchorneopsis, have small 3-colporate pollen with punctate tecta. Pollen of the five genera assigned to tribe Bernardieae, Bernardia, Necepsia, Paranecepsia, Discocleidion and Adenophaedra is of a similar, but unspecialized type--a punctate, deeply punctate, or microreticulate tectum, small endoaperture, and usually a prominent margo. The present concept of tribe Pycnocomeae as comprising Pycnocoma, Droceloncia, Argomuellera, Blumeodendron, Podadenia, Ptychopyxis and Botryophora is not supported by the pollen data. Members of Pycnocoma have pollen with a derived exine structure--a conspicuously thick endexine throughout the grain, threadlike foot layers, and columellae reduced to a point on the proximal side of the tectal elements. The pollen data are somewhat ambiguous about a close relationship between Droceloncia and Argomuellera, the two remaining genera in the subtribe Pycnocominae. The genera allied as subtribe Blumeodendrinae, Blumeodendron, Podadenia, Ptychopyxis, and Botryophora, share pollen with short narrow colpi, a croton sculpture, and mostly irregular columellae.

D. Walcott from 1883-1886. In 1885, he spent four months, mostly in Alabama, measuring sections of Paleozoic rocks and searching for fossils, mainly in the Cambrian. In 1888, Walcott concurred with foreign authorities that the rocks called Middle Cambrian in North America were Early Cambrian in age and vice versa, requiring a new interpretation of Cambrian strata. Curtice returned to Alabama for geologic investigations in 1892, and again briefly with Walcott in 1895.

Some 2000 birds settle on the protected Nature Conservancy site to breed. The blue heron ranges across the nation, feeding and nesting on lakes and streams up to Alaska and northern Canada, and even appearing in urban settings. The blue heron genus is virtually unchanged from its predecessors in the fossil record. An opportunist, the blue heron population has been stable for the past 30 years, illustrating a rebound after the DDT-contaminated years. The bird capitalizes on the ponds and wetlands developed for recreational fishing. Its vulnerability lies in the reduced number of protected sites for nesting colonies.

If this situation arises among species that exhibit resource defence polygyny where males and females of different species reside in the same territories, there may be some conflict between mate choice based on territory-holding ability (sexual selection) and mate choice for correct species. We investigated this in a population of fur seals where three species are sympatric and where some females breed in the territories of heterospecific males, and where interspecific matings and hybrid pups are observed. The territorial status of males and the birthing sites of females were determined during daily observations, as were the movements of males and females, the location of matings and mating partners. DNA extracted from skin samples was used to determine paternities using DNA fingerprinting and the mtDNA genotype of individuals. Individuals were also classed on the basis of species-typical phenotype. We found that extra-territory inseminations (ETIs) were significantly more prevalent (67%) when territorial males and resident females were of different phenotype than when of similar phenotype (27%), but mtDNA genotype had no effect on the rate of ETIs. ETIs were probably by males with the same phenotype, as pups born to these females in the following season had the same phenotype as their mothers, suggesting they were not hybrids. These results suggest that within the resource defence polygynous mating system of these sympatric fur seals, female mate choice is more influenced by male phenotype than genotype. Contrary to our predictions, our study indicates that potential conflict between mate choice based on sexual selection and species recognition is unlikely, because females have some capacity to discriminate between males both within and between species on phenotypic traits additional to those under sexual selection. Although at least 25% of the pups born in this study were hybrid, this study can only support reinforcement theory if hybrids have reduced fitness. The fitness of hybrids among the species studied is currently unknown.

Nonetheless, several recent molecular analyses claim to show that because several interordinal splits occurred during the Cretaceous, a major therian radiation was then underway. This claim conflicts with statistical evidence from the well-sampled latest Cretaceous and Cenozoic North American fossil record. Paleofaunal data confirm that there were fewer mammalian species during the latest Cretaceous than during any interval of the Cenozoic, and that a massive diversification took place during the early Paleocene, immediately after a mass extinction. Measurement data show that Cretaceous mammals were on average small and occupied a narrow range of body sizes; after the Cretaceous-Tertiary mass extinction, there was a rapid and permanent shift in the mean. The fact that there was an early Cenozoic mammalian radiation is entirely compatible with the existence of a few Cretaceous splits among modern mammal lineages.

The abundant cranial and postcranial material of the fossil rodent was recovered from old beach dunes that are late Quaternary in age (probably late Holocene). Noronhomys vespuccii retains incomplete mesolophs on its moderately hypsodont molars and is compared with other tetralophodont oryzomyines (sensu Voss and Carleton, 1993), especially Lundomys molitor and species of Holochilus. Morphometric analyses conducted separately on craniodental, mandibular, and femoral measurements reveal the sample of Noronhomys to be equally differentiated from those of Lundomys and Holochilus. Based on the criterion of parsimony, phylogenetic analyses of 35 craniodental characters strongly support the recent common ancestry of the new form and Holochilus. The clade (Pseudoryzomys (Lundomys (Holochilus-Noronhomys))) appears to represent a lineage of semiaquatic rodents that differentiated from an oryzomyine ancestry in savanna landscapes of southern South America. Morphometric results and anatomical details of the pelvic limb, however, suggest that Noronhomys was not a semiaquatic form. It is hypothesized that such aquatic skeletomuscular adaptations were lost (reversed) when the progenitor of Noronhomys became stranded on a small oceanic island where palustrine habitats were scarce or absent. The specific patronym of the extinct rodent refers to Amerigo Vespucci's disputed landfall on Fernando de Noronha in 1503 and his possible sighting of "very large rats" on that island. If the species Noronhomys vespuccii were alive in 1503, it became extinct shortly thereafter due to the usual anthropogenic causes that have extirpated so many vertebrate species on islands.

The heavy isotope enrichment at the crystal surface propagates into the crystal by diffusion, and measurement of evaporation rates and of the isotope diffusion profile can give the size of the fractionation effect and the diffusion coefficient for each element. The results support a model of isotopic fractionation of (super 26) Mg/ (super 24) Mg under diffusion-controlled conditions such that isotopic fractionation during evaporation is restricted to the vicinity of the crystal surface. The solid-gas fractionation factor of (super 26) Mg/ (super 24) Mg is smaller than the theoretical ratio indicating more complicated gas speciation than a monatomic Mg gas. Mg diffusion along the forsterite a-axis has a high activation energy of 608 kJ/mole.

More than 30 Mn oxide minerals occur in a wide variety of geological settings. They are major components of Mn nodules that pave huge areas of the ocean floor and bottoms of many fresh-water lakes. Mn oxide minerals are ubiquitous in soils and sediments and participate in a variety of chemical reactions that affect groundwater and bulk soil composition. Their typical occurrence as fine-grained mixtures makes it difficult to study their atomic structures and crystal chemistries. In recent years, however, investigations using transmission electron microscopy and powder x-ray and neutron diffraction methods have provided important new insights into the structures and properties of these materials. The crystal structures for todorokite and birnessite, two of the more common Mn oxide minerals in terrestrial deposits and ocean nodules, were determined by using powder x-ray diffraction data and the Rietveld refinement method. Because of the large tunnels in todorokite and related structures there is considerable interest in the use of these materials and synthetic analogues as catalysts and cation exchange agents. Birnessite-group minerals have layer structures and readily undergo oxidation reduction and cation-exchange reactions and play a major role in controlling groundwater chemistry.

AN - 17217384; 4501239 AB - Brood parasitism has evolved repeatedly in insects, and is especially diverse within bees. Little attention has been given to the evolution of structural modifications associated with parasitism, in contrast to behavior. Female parasitic bees tend to converge on a suite of characters, some of which may involve loss of characters associated with pollen-collecting or nest-making, whereas others may represent new characters used in a parasitic lifestyle. Certain external traits of female parasites resemble those of males, and this study compares the phenetic similarity of males and females of a social parasite, Paralictus asteris Mitchell, and its host, Lasioglossum (Dialictus) imitatum (Smith). Results are consistent with the hypothesis that some structural traits associated with parasitism may be derived from the expression of male-like traits in females.

This event is related to blockage of the Pelusiac branch and breaking through of a new distributary to the west of present-day Port Said, probably representing initiation of the Damietta branch. The sand is of analytically identical age throughout the area and was deposited within less than approximately 60 yr, as indicated by (super 14) C and amino acid racemization analyses of Donax shells from a series of cores. Radiocarbon dates, in combination with historical accounts by Al-Jakubi, who found the strand plain already in existence when he visited the area in the late 800s, place this event in the early 800s. Nilometer flood records suggest that the sequence of great floods of 813, 816, and 820 may have been the triggering events. This sudden displacement of sand caused Pelusium, then the principal port and fortified city of the northeastern Nile Delta located at the mouth of the Pelusiac branch, to be cut off from both the Nile and the Mediterranean, and led to its decline and eventual abandonment by the 12th century, when the Crusaders arrived.

The goal was to quantify the effects of a wide range of precipitation, representative of inter-annual variations in weather in this region. The discharges measured included both overland storm flows and groundwater, since the aquifers were perched on a clay aquiclude. Precipitation varied from 824 to 1684 mm/yr and area-weighted Rhode River watershed discharge varied from 130 to 669 mm/yr with an average of 332 mm/yr or 29.1 percent of average precipitation. Average annual discharges from three first-order watersheds were significantly lower per surface area and varied from 16.0 to 21.9 percent of precipitation. Winter season precipitation varied from 125 to 541 mm. Area-weighted Rhode River winter discharge varied from 26.3 to 230 mm with an average of 115 mm or 43.9 percent of average precipitation. Spring season precipitation varied from 124 to 510 mm and watershed discharge varied from 40.0 to 321 mm with an average of 138 mm or 46.9 percent of average precipitation. In the summer and fall seasons, watershed discharge averaged 40.6 and 40.9 mm or 13.5 and 14.3 percent of average precipitation, respectively. Except in winter, the proportion of precipitation discharged in the streams increased rapidly with increasing volume of precipitation. Stream order showed a higher correlation with volume of discharge than vegetative cover on the watershed.

In the first study, Pleistocene reef coral assemblages from Papua New Guinea show pronounced constancy in taxonomic composition and species diversity between 125 and 30 ka (thousand years). Spatial differences in reef coral community composition during successive high stands of sea level were greater among sites of the same age than among reefs of different ages, even though global changes in sea level, atmospheric CO sub(2) concentration, tropical benthic habitat area, and temperature varied at each high sea level stand. Thus, local environmental variation associated with runoff from the land had greater influence on reef coral community composition than variation in global climate and sea level. Proportional sampling from a regional species pool does not explain the temporal persistence and local factors likely played a major role. Examination of coral reef response to global change should not only involve regional diversity patterns but also local ecological factors, and the interactive effects of local and global environmental change. In the second study, Pleistocene extinction of two widespread, strictly insular species of Caribbean reef corals, Pocillopora cf. palmata (Geister, 1975) and an organ-pipe growth form of the Montastraea "annularis" species complex, was natural and did not involve gradual decrease in range and abundance, but was sudden (thousands of years) throughout the entire range. One explanation is that sea level drop at the Last Glacial Maximum (LGM--18 ka) resulted in a threshold of habitat reduction, and caused disruption of coral metapopulation structure. Threshold effects predicted by metapopulation dynamics may also explain the apparent paradox of the large amount of degraded modern reef habitat without any known modern-day reef coral extinctions. The rapid extinction of widespread Pleistocene species emphasizes the vulnerability of reef corals in the face of present rapid environmental and climatic change.

These watersheds have perched aquifers so all groundwater discharges as well as surface runoff were measured at V-notch weirs equipped with volume-integrating, flow-proportional samplers. Interannual variations in annual and seasonal precipitation during this study spanned approximately the range of 160-yr weather records in the region. Annual total-P area yields from the overall watershed varied 28-fold, correlations of all P-species fluxes with precipitation were highly significant, and power function regressions of precipitation vs. P-flux explained from 42 to 55% of the variance in the latter. Phosphorus fluxes from a cropland watershed were much higher and more variable with volume of precipitation, while fluxes from a forested watershed were much lower and primarily composed of organic P. Correlations of P fluxes with precipitation were higher in the spring. Annual and seasonal P concentrations also often increased significantly with precipitation. Variations in seasonal mean air temperature sometimes explained significant amounts of variance in P fluxes, especially phosphate from cropland. A regression model was used to construct graphical and tabular summaries.

These watersheds have perched aquifers so all groundwater discharges as well as surface runoff were measured at V-notch weirs which included volume-integrating flow-proportional samplers. Interannual variations in annual and seasonal precipitation during this study spanned approximately the range of 160 yr weather records in the region. Annual total-N area yields from the overall watershed varied nine-fold, correlations of all N-parameter discharges with precipitation were highly significant, and power function regressions of precipitation vs N-discharge explained from 36 to 59% of the variance. Nitrogen fluxes from a cropland watershed were much higher and more variable with volume of precipitation, while fluxes from a forested watershed were much lower and were primarily composed of organic-N. Correlations of N-fluxes with precipitation were higher in the winter and spring. Annual and seasonal N-concentrations also often increased significantly with precipitation. Variations in seasonal air temperature sometimes explained significant amounts of variance in N-discharges, especially ammonium.

The influence of Asian American artists on US abstract expressionism is discussed. The import of the museum exhibit, "A More Perfect Union: Japanese Americans & the Constitution," in articulating the treatment of Japanese Americans during WWII is examined, & its ambiguous representation of Hawaiian Japanese Americans' participation in WWII is lamented. It is concluded that increased coverage in national museums may encourage Japanese Americans in HI to become involved in social reform. 19 References. J. W.

In the early eighteenth century, most western natural philosophers accepted the view, inherited from Aristotle and confirmed on mechanistic grounds by Isaac Newton, that interplanetary space is empty of solid matter. In the final decade of that century, two books, one by Ernst F. F. Chladni of Wittenberg and one by James Hutton of Edinburgh, contributed to the rise of meteorite studies and uniformitarian geology, respectively. Although they arose almost simultaneously, these two branches of science, one of which postulated the fall to Earth of solid bodies from space while the other endorsed only strictly endogenous processes acting upon the Earth, evolved separately over the next 200 years. This paper traces the long estrangement between mainstream geology and the science of meteorites. The two disciplines collided head-on in 1980 when a team of scientists headed by the physicist, Luis Alvarez, of the University of California, hypothesized that the massive extinctions at the end of the Cretaceous were triggered by the hypervelocity impact of a large body from space. Many geologists rejected outright such an exotic cause. More recently, as evidence has accumulated for the K-T impact as well as for many other crater-forming impacts, we are beginning to realize that unpredictable collisions have played a role of fundamental importance throughout the history of the solar system.

The GPS signals are delayed by various gases when traversing the atmosphere. The delay due to water vapour, the wet delay, is difficult to model using ground surface data and is thus often estimated from the GPS data. In order to obtain the most accurate results from the GPS processing, a modelling of the horizontal distribution of the wet delay may be necessary. Through simulations, three such models are evaluated, one of which is developed in this paper. In the first model the water vapour is assumed to be horizontally stratified, thus the wet delay can be described by only one zenith parameter. The second model gives the wet delay with one zenith and two horizontal gradient parameters. The third model uses the correlation between the wet-delay values in different directions. It is found that for large gradients and strong turbulence the two latter models yield lower errors in the estimated vertical coordinate and wet-delay parameters. For large gradients this improvement is up to 7 mm in the zenith wet-delay parameter, from 9 mm down to 2 and 4 mm for the second and third models, respectively.

As in live Archaias, skeletal rods in dead foraminifera break down to granular minimicrite (<1 mu m). This minimicrite may, in turn, recrystallize to pseudomicrite, a mosaic of very small equant crystallites (0.02-0.05 mu m), which are typically aligned in radial or blocky patterns. Minimicrite and pseudomicrite also recrystallize to blocky micrite (1-4 mu m). Processes of post-mortem recrystallization in Halimeda are similar to those in Archaias, but also involve the growth of skeletal needles to form blocky micritic textures. Textural alteration of crystals from minimicrite to pseudomicrite or micrite may involve changes in mineralogy from Mg-calcite to aragonite or from aragonite to Mg-calcite. Progressive recrystallization in Halimeda and Archaias results in gradual micritization. Concomitant with the formation of pseudomicrite and micrite, the golden brown color characteristic of live and recently dead specimens, as seen in plane polarized light, is progressively replaced by gray cryptocrystalline textures. Our detailed studies of this micritization process indicate that the widely held concept that micritization results solely by the infilling of microborings is an oversimplification of a complex process that often involves recrystallization. Our studies further indicate that carbonate recrystallization is not restricted to the realms of vadose and burial diagenesis, but is a widespread early diagenetic process in shallow tropical seas throughout the world. Reasons for early textural and mineralogical crystal alteration are largely unknown, but are clearly not related to mineralogical stabilization to low Mg-calcite, a commonly cited driving force for recrystallization.

Original skeletal needles are being extensively recrystallized with no change in mineralogy. In H. incrassata, the original skeletal needles are aragonite, 1 to 3 microns long, and 0.1 to 0.3 microns wide. These needles are best preserved in the uppermost calcified segments of the thallus. With increasing maturity of the segments, these needles alter to anhedral equant minimicrite (<1 micron). Similarly, original Mg calcite skeletal needles or rods in A. angulatis, which are 1 to 2 microns long and 0.1 micron wide, are recrystallized in older sections of the test to form dense minimicrite. Reasons for the alteration of skeletal needles to minimicrite in live H. incrassata and A. angulatis are still poorly understood. It is thought that these needles, which may have had organic envelopes that controlled their size and shape, have broken down to their basic polycrystalline sub-structure following the destruction of these organic envelopes. This micritization process is accompanied by additional precipitation of calcium carbonate, which is indicated by a marked increase of density in areas of micritization. This pattern of alternating etching and reprecipitation could be related to variations in rates of respiration and photosynthesis in the thallus of H. incrassata and with the algal symbionts in A. angulatis after the breakdown of the original organic envelopes.

We studied >200 fossil leaf sites (>300 taxa) and 60 palynological samples (92 taxa) from below and above the LPTM in the Bighorn Basin of northwestern Wyoming (paleolatitude 47 N). Inter-sample duration averages 40 ky for the palynological study and 80 ky for the leaf study. Neither leaves nor palynomorphs are preserved in the LPTM interval itself. Changes in floral composition and diversity were not dramatic. Approximately 15% of common megafossil taxa had last appearances in the approximately 250 ky before the LPTM, and 12% had first appearances in the approximately 250 ky after it. Megafloral richness declined by about 20% through the million-year interval including the LPTM, largely as an artifact of declining sample density. Three of four taxa that appeared immediately post-LPTM were highly dispersible ferns. There were no last appearances of common palynomorphs in the approximately 250 ky prior to the LPTM, and only two moderately common taxa had first appearances in the approximately 250 ky following. There were major shifts in relative abundances; formerly dominant walnut family pollen types decreased markedly, and elms, alder, and Tiliaceae/Malvaceae increased. Within sample richness of palynofloras increased slightly from pre- to post-LPTM time. The subdued changes in floral composition and diversity from pre- to post-LPTM time contrast with the major changes in mammalian faunal composition and diversity that occurred at the same time in the same area. This is surprising because of the sensitivity of plants to climatic change. We hypothesize that the small amount of floral change reflects either the failure of most plant populations to expand across high-latitude land bridges during the geologically brief LPTM, or their inability to establish themselves in the pre-existing vegetation of North America.

Research in living forests has shown significant latitudinal and moisture-related gradients in the diversity and intensity of plant-insect interactions. Our hypothesis is that past changes in temperature or precipitation would have effects analogous to these gradients, illuminating the role of climate as a primary selective force on terrestrial life.To test our hypothesis, we studied two successive climate changes in the Rocky Mountains of southwestern Wyoming (greater Green River Basin, Fort Union and Wasatch formations) and adjacent northeastern Utah (Uinta Basin, Green River Formation): (1) temperature increase from the late Paleocene to the early Eocene and (2) increased seasonality of rainfall from the early to the middle Eocene. From each time interval above, we examined a large sample of well-preserved dicot leaves bearing diverse insect damage. Leaves were sampled quantitatively (2433 identified specimens) and qualitatively ( approximately 10000 identified specimens) and were scored for 45 types of insect damage representing four functional feeding groups: external feeding, galling, mining, and piercing-and-sucking. Higher temperatures in the early Eocene were associated with significant increases in insect attack frequencies and in insect damage diversity per host plant, closely matching modern trends associated with decreasing latitude. Rainfall seasonality in the middle Eocene brought an increase in overall leaf toughness. Consequently, the sizes of feeding holes and mines decreased sharply independent of leaf size. Galling diversity rose, supporting the positive correlation of galling diversity with climatic dryness today. Increasing variance was found through the study interval in the number of damage types found on individual plant hosts, suggesting a developing dichotomy in defense strategy between palatable, short-lived leaves of deciduous plants, dominant in the Paleocene, to less palatable, longer-lived evergreen species, which became more abundant and diverse in the Eocene.

Except for its much larger size, the humerus of this specimen is identical to that of Anatalavis rex (Shufeldt) from the late Cretaceous or early Paleocene of New Jersey. The Eocene specimen is described as a new species, Anatalavis oxfordi, and the genus Anatalavis is transferred from the form-family Graculavidae to a new subfamily, Anatalavinae, of the Anseranatidae. Anatalavis is characterized by a very broad duck-like bill, a proportionately very short and robust humerus, and an anterior portion of the pelvis resembling that of ibises and other wading birds more than that of any known anseriform. Other features of its osteology are unique within the order. JF - Smithsonian Contributions to Paleobiology AU - Olson, Storrs L A2 - Olson, Storrs L.

A recently identified megapode from late Oligocene deposits at Lake Pinpa, central Australia, is older than any previously reported megapode taxon and is only about two-thirds the size of the smallest living species. It probably inhabited riparian forests bordered by tropical savanna woodland in the Oligocene environment of Lake Pinpa, occupying a role similar to that of the Orange-footed Scrubfowl, Megapodius reinwardt Dumont, in tropical Australia today. Although the new fossil confirms the presence of the Megapodiidae in Australia as early as the late Oligocene, it provides no information on the origins and relationships of the family, or on the evolution of its distinctive method of incubation.

In particular, it required a relatively high retracting force. Three sources of this force evolved. (1) A powerful M. retractor palatini (especially in Tinamiformes and Apteryx), originating primarily on the vomer and pterygoid, developed to provide direct muscular connection between the dermal palate and the cranial base. It apparently evolved due to a joining of the medial portions of the pterygoid and mandibular depressor muscles, which were aligned by development of the proc. mandibulae medialis (a character unique to birds). (2) The ancestral pseudotemporalis muscle developed into two portions, a large postorbital portion and an almost horizontally oriented intramandibular portion. Each portion serves to increase the retraction ability of the muscle as a whole.

Its evolutionary development was temporarily retarded by reduction of one of its places of origin-the upper temporal arch.

The holotype includes the manus, which was previously unknown in the Jungornithidae. In comparison with early Oligocene Jungornis, the new form is less advanced evolutionarily, and, in particular, it lacks certain characters shared by Jungornis and the Trochilidae. An emended diagnosis of the family Jungornithidae is given. Taking into account that both Jungornis and Argornis possess an apodid-like deltopectoral crest, revealing their highly developed ability for gliding flight, the appearance of trochilid-like features in Jungornis demonstrates a real possibility that hovering specializations developed from gliding adaptations. This conclusion conforms with the results of a comparative analysis of the transformation of forelimb muscles in three modern apodiform families.

The new specimen is referred to the Incredible Teratorn, Teratornis incredibilis Howard (1952), and a reexamination of all the specimens previously referred to this taxon reveals sufficient grounds to erect a new genus for this species. The size of the new partial humerus suggests that the bird had a wingspan of approximately 5 m, which is the same estimate previously given for the Incredible Teratorn.

For a number of reasons the method is not generally applicable to birds; however, most of these objections do not apply to obligate seabirds. This paper treats 31 West Palearctic late Pleistocene faunas from 22 sites containing two or more species of obligate seabirds. The analysis suggests that the waters around the British Isles during the last (Eemian) interglacial were slightly warmer than during the present interglacial, that conditions in the western Mediterranean during much of the last glaciation were similar to those found in the Bay of Biscay and around the British Isles at the present time, and that conditions in the Norwegian Sea during the warmest part of the mid-Weichselian interstadial were similar to those found off the west coast of Spitzbergen today. The stratigraphic position of a number of undated avifaunas containing seabirds is discussed based on the species composition of the seabirds.

Cultural remains were deposited over several centuries and were dated by association with archaeological artifacts to 400-100 BC. Thirty-nine species were identified in the bird assemblage. Among these species, 10 are represented by rare breeding and rare vagrant birds, indicating a somewhat warmer climate at the Ob' River mouth than at present. The remains of Golden Eagles and White-tailed Eagles excavated from sacrificial areas of the settlement are of special interest. These findings indicate special cultural attention to and attitude toward eagles, which may have been kept in captivity. Based on bird remains, the site has provided the earliest evidence of eagle worship in Siberia.

AN - 52361624; 2000-035940 AB - The oldest known remains of the Enantiornithes come from the Early Cretaceous of Spain and northeast China. They represent birds capable of flight, although it was not efficient enough to enable them to fly over the Turgai Strait, which at that time separated the eastern and western parts of the present-day Palaearctic. A comparison of the coastlines of the continents in consecutive epochs of the Jurassic and Cretaceous suggests that in order to spread by land over all of Eurasia, both Americas, and Australia, the Enantiornithes would have had to differentiate at the latest by the Middle Jurassic (Bajocian), or about 25 million years before the period from which Archaeopteryx is known (Tithonian).

A close parallel is found between the late Pleistocene avian communities of the Pityusics and the prehuman avifauna of the Hawaiian Islands, whereas the communities from the remaining western Mediterranean islands were similar ecologically to those of the eastern Mediterranean islands. A key factor for the understanding of avian community structure is the presence or absence of middle-sized herbivorous mammals (Myotragus balearicus Bate on the Gymnesic Islands and Megaceros cazioti (Deperet) on Corsica and Sardinia).

Birds share with crocodilians and, to a lesser extent, mammals, a complex mode of tooth implantation, with deep sockets walled lingually by the dentary, maxilla, or premaxilla. These walls crowd the replacing teeth so that early in ontogeny the teeth migrate labially and continue their development under the crown of their predecessor. They thus form a vertical tooth family, as opposed to the horizontal tooth family found in dinosaurs and most other tetrapods. Birds, crocodilians, and mammals have root cementum on their teeth and presumably attach teeth to the socket with periodontal ligaments. The sockets in mammals and presumably in birds are formed by the outside of the periodontal sac, whereas cementum is deposited by the inside of the sac. Bird teeth are initially formed in a groove, and ontogenetically the sockets (in socket-forming species) form first at the front of the jaw. Socket formation then proceeds posteriorly, as in crocodilians. Young dinosaurs have the lingual side of the jaw around the teeth open, so that the roots are exposed. The sockets form around dinosaur teeth as bone of attachment, which is probably the same periodontal bone that forms sockets in mammals, crocodilians, and birds. The sites of new tooth formation extend lingually within the so-called "special foramina" that separate the interdental plates. The interdental plates represent the surrounding attachment bone and are similar to the attachment bone in pleurodont lizards. In fact, dinosaurs might be characterized as having a superpleurodonty that results in sockets.

Three extinct taxa, probably new to science, include a large Tyto, a long-legged Athene, and a small species of Corvidae to be described later. Paleoenvironmental reconstruction of the site indicates a temperate climate, like the present or slightly colder.

No specific avian similarities could be found in the jaws and palate of dromaeosaurids. The ectopterygoid of the oviraptorids connects the lacrimal to the palatine, as does the avian uncinate (lacrimopalatine). This and other cranial similarities between the oviraptorosaurs and ornithurine birds raise the possibility that oviraptorosaurs are the earliest known flightless birds. With Archaeopteryx and the theropods providing evidence of plesiomorphic conditions, similarities in the mandibles, teeth, and tooth implantation in the Ichthyornithidae and Hesperornithidae may be interpreted as synapomorphies supporting monophyly of the Odontognathae.

Twenty species of seabirds and one land bird are represented by the fossils. This may underestimate the prehuman species richness because two of the 10 indigenous species that now breed on the island are not represented among the fossils. Lengths of bones for all common species on Amsterdam are compared with those of populations elsewhere. On Amsterdam, Great-winged Petrel (Pterodroma macroptera (Smith)) and Grey Petrel (Procellaria cinerea Gmelin) populations were composed of individuals of relatively small mean size. The Macgillivray's Prion (Pachyptila macgillivrayi (Mathews)) is shown to be specifically distinct from the Broad-billed Prion (P. vittata (Forster)) and Salvin's Prion (P. salvini (Mathews)), based on osteological measurements.

Representatives of extinct endemic Mascarene taxa, such as the Raphidae, Aphanapteryx, Erythromachus, and large parrots of the genera Lophopsittacus and Necropsittacus, are so far unknown from Reunion. Except for Fulica newtonii, which probably colonized Reunion from Mauritius, and Dryolimnas augusti, all the other forms appear to have had normal or nearly normal flying ability. It is possible that Reunion was colonized by the ancestors of the same forms that colonized Mauritius and Rodrigues, but these forms may have been exterminated during the very explosive events of the last phase of volcanic activity of Piton des Neiges, which took place between 300,000 and 200,000 years ago. Reunion would then have been colonized again by forms that perhaps have not had enough time to lose their ability to fly. After the arrival of the first Europeans, all the larger endemic land birds became extinct, with the exception of Circus maillardi Verreaux. Although most of them were not morphologically flightless, and although the topography of the island was very different, these birds became extinct on Reunion as rapidly as on the other Mascarene islands.

AN - 52360560; 2000-035943 AB - To achieve a better understanding of the function of the M. supracoracoideus in extant birds, we measured the mechanical properties and actions of the supracoracoideus in the European Starling (Sturnus vulgaris Linnaeus) and a pigeon (Columba livia Gmelin). We performed three sets of acute in situ experiments by direct nerve stimulation. We measured length-active and length-passive tension, forces of humeral elevation and rotation (torque), and humeral excursion (elevation and rotation). The supracoracoideus is capable of generating a tetanic force 7-10 times the bird's body weight, imparts a torque about the longitudinal axis that is greater than its force of humeral elevation, and, when tetanically stimulated, elevates the humerus a limited 50 degrees -60 degrees above the horizontal but rotates it through 80 degrees . We conclude that the primary role of the supracoracoideus is high-velocity rotation of the humerus, a movement critical to achieving the upstroke portion of the wingbeat cycle. In addition, we propose that high-velocity humeral rotation may also serve to augment supination of the wrist during upstroke. A morphologically derived supracoracoideus to produce rapid humeral rotation and the skeletal features associated with it, an acrocoracoid, triosseal canal, and tuberculum dorsale, are not evident in Archaeopteryx or Sinornis. These features also appear undeveloped in Iberomesornis and Concornis, are unknown in Cathayornis, and apparently are not preserved in the most recent find, Confuciusornis.

Otogornis genghisi Hou, 1994, of the Yijinhouluo Formation (earliest Cretaceous or latest Jurassic) of Ordos, China, was first described as Aves incertae sedis. Ambiortus and Otogornis share specialized characters, such as a thickened, three-edged acrocoracoid with an acute top; a flat, wide humeral articular facet of the scapula; ventral position of a small, oval humeral articular head; and a thin, long intermediate phalanx of the major wing digit. The generic status of Otogornis is supported by some other diagnostic characters. Several advanced characters demonstrate the assignment of Ambiortus and Otogornis to the Palaeognathae. These two forms show the occurrence of paleognathous birds in the Early Cretaceous of Central Asia.

The great diversity of condors that occurred in the late Cenozoic of this region comprises three genera and at least four species, namely, Dryornis pampeanus Moreno and Mercerat, Vultur gryphus Linnaeus, Geronogyps reliquus Campbell, and an indeterminate vulturid probably belonging to a new genus and species. The presence of Geronogyps reliquus (up to now restricted to the Pleistocene of Peru) in the Pleistocene sediments of the Pampean region extends considerably the geographic range of the species.

Lagopus lagopus and L. mutus from most pre-Holocene deposits are found to differ allometrically from modern samples. This difference is best seen in the tarsometatarsus, which often is more robust in both species in the Pleistocene and in turn may reflect greater body weight. Possible correlations between this phenomenon and the climatic and ecological conditions of the past, as well as the possibility that these birds were less sedentary, are discussed.

A humerus is referred to the anseriform Presbyornis isoni Olson, previously known from a less complete humerus from the late Paleocene of Maryland. All known specimens of Dakotornis cooperi Erickson, referable to the extinct charadriiform form-family Graculavidae, are reviewed. A cervical vertebra and a tarsometatarsal fragment, both within the probable body-size range of Dakotornis cooperi but probably representing different taxa, are referred to the Graculavidae. Another distal end of a tarsometatarsus, from perhaps the smallest currently known Paleocene bird, also is referred to the Graculavidae. These two tarsometatarsi exhibit a mosaic of charadriiform characters. Together with the tarsometatarsus of Telmatornis priscus Marsh, three size classes of North American Paleocene graculavid tarsometatarsi are now known.

These faunal associations are recognizable in deposits dating from the last glacial (Otiran) and the Holocene periods. Sites in western regions of South Island exhibit significant differences in the fauna's species composition between deposits formed in the last glacial period and those from the present interglacial period, but sites in the east do not. Several species became regionally extinct at the end of the glacial period, but all survived in the east until the present millennium. Although climate change caused the redistribution of species, all Late Quaternary extinctions in New Zealand were ultimately caused by humans during the last 1000 years.

A new look at the hand of Archaeopteryx AN - 52359584; 2000-035941 AB - A detailed examination of wrist and manus skeletons in Archaeopteryx, and their comparison with those of modern birds, demonstrates an overwhelmingly avian appearance, much more so than has been previously recognized. Many workers have considered feathers to be the only indisputable evidence for the avian identity of this early bird. Although only a few skeletal characters have been used to support its avian identity, we believe that this is due to a lack of detail in previous analyses. We offer a list of eight uniquely derived avian characters or character complexes in the wrist and manus of Archaeopteryx. This further indicates that Archaeopteryx is a bird, with wings used for flying rather than for predation, and provides some fundamental skeletal differences between the oldest birds and their immediate ancestors. We extend our comparisons to the only other bird with Archaeopteryx-like morphology in the manus, Confuciusornis, and show how the wrist and manus may provide useful clues for discerning potentially older and unknown birds in the future. In addition, the large number of uniquely avian characters in the wrist and manus contrasts with a more primitive anatomy in other parts, providing another example of mosaic evolution, as the structure of the wing modernized at a more rapid rate than other anatomical units.

Aquila bivia, new species, is known from 33 skeletal elements from Inglis 1A, Citrus County, Florida, and from a partial skeleton from 111 Ranch, Graham County, Arizona. It was a large eagle, approximately 10%-15% larger than females of modern A. chrysaetos (Linnaeus), and it is the first valid fossil species in this genus to be described from North America. Amplibuteo concordatus, new species, is known from 13 skeletal elements from Haile 7C, Alachua County, and Inglis 1C, Citrus County, Florida, and from three specimens from Duncan, Greenlee County, Arizona. It is the third species of the genus to be described, and it represents the earliest occurrence of this genus. These two new taxa add to a growing list of vertebrates with fossil distributions in both the Florida peninsula and western North America, which reflects a corridor of common habitat that once united these regions. This corridor initially developed during glacial intervals in the late Pliocene, when numerous taxa of mammals, birds, reptiles, and plants first appear in the fossil record of Florida. The corridor probably was composed largely of dry thornscrub and savannah communities, but it also may have had a mosaic of lakes, wetlands, and hammocks that allowed dispersal of a variety of species that reflect these communities.

Recent field research (1988-1993) has dramatically augmented the earlier collections and has provided, for the first time, a sound stratigraphic and radiometric chronology for this rich subfossil avifauna. Most of these bones have been found naturally deposited in the buried soil horizons of coastal sand dunes or in limestone caves, but some are of archeological origin, deposited by human agency in coastal dune middens or, occasionally, in dwelling caves. Most, if not all, of the avian remains are of early Holocene or younger age, as indicated by a series of some 65 accelerator-mass-spectometry radiocarbon dates ranging from ca. 7000 yrs BP to ca. 300 yrs BP. The Holocene fossil record for, and patterns of evolution and extinction within, the Chatham Islands' avifauna are documented and discussed. Taxonomic studies indicate that several taxa, all extinct, can no longer be considered inseparable from their mainland counterparts; among these are as yet undescribed species of Eudyptes, Tadorna, Mergus, and Nestor.

This implies that extinction intensity is falling off approximately as the reciprocal of time. We demonstrate that this observation alone is sufficient to explain the existence of the proposed power-law forms in the distribution of the sizes of extinction events and in the power spectrum of Phanerozoic extinction, results that previously have been explained by appealing to self-organized critical theories of evolutionary dynamics.

Stochastic thinking in evolutionary biology and paleobiology has solidified the use of a statistical notion of chance, but the idea of chance in evolutionary studies goes beyond statistics. A duality arises from the use of a statistical meaning on the one hand, and a more strictly evolutionary meaning on the other. The former implies a combination of indiscriminate sampling and unpredictability due to multiple causes; the latter codifies independence from adaptation and the directionality imposed by natural selection. Often these meanings are kept separate in evolutionary research, used in isolation according to the empirical situation or the goal of the investigator (recognition of pattern versus process). I argue that evolutionary studies in general and paleobiological studies in particular can benefit from the simultaneous application of statistical and evolutionary notions of chance. Following some background on the notion of chance and its use, I discuss a series of examples in which insight can be gained by explicit consideration of both meanings. Thus, typologies of extinction become clearer when phenomena like wanton extinction are made explicit; exaptive radiations are exposed as an alternative to adaptive radiations; the possible non-adaptive nature of deterministic chaos becomes sensible; the nonrandomness of community-assembly is put into question; parallel taxonomies of sorting rooted in different notions of nonrandomness are suggested as a means of facilitating understanding of relationships across the hierarchy; developmental constraints and self-organization are more easily distinguished from selective constraints; and a new term, "incidentals," is suggested to refer to both exaptations and nonaptations. Finally, I point to ways in which the dichotomy between chance and necessity can be approached in evolutionary theory, by showing that the dual nature of chance in evolution entails a distinction between functional and structural necessity, and that chance ultimately becomes a unifying concept for a number of criticisms to neo-Darwinism.

It is an artificial assemblage of slender to bulbous, and allegedly, featureless gastropods. Newly described protoconchs from well-preserved late Paleozoic subulitids have been employed in a phylogenetic analysis along with teleoconch characters and stratigraphic data. Two matrixes with 18 shell and two stratigraphic characters were analyzed. One includes most genera traditionally assigned to the Subulitoidea (28 genera, five outgroups). The second is restricted to genera with known protoconchs (14 genera, three outgroups). The comprehensive analysis is less informative because the number of characters is much smaller than the number of taxa and many character states could not be determined. It produced 420 trees (72 steps). The 50% majority-rule consensus tree is fairly consistent with the fossil record. However, the outgroup taxa fall within subulitoid clades and the Soleniscidae, an otherwise well supported clade, are not monophyletic. The analysis restricted to genera with protoconch characters produced 42 trees (41 steps). The 50% majority-rule and the strict consensus trees produced three distinct clades, amongst them the Soleniscidae, arising from a polytomy. This analysis provides little support for the monophyly of the traditional Subulitoidea. However, within this heterogenous assemblage distinct clades can be recognized by their protoconch morphology. All known protoconchs of subulitids are dextral like the adult shell. Therefore, protoconch orientation is not informative for the phylogenetic analysis, but it is informative for higher level assignment, i.e., the late Paleozoic subulitids are caenogastropods; in contrast to previous suggestions, we found no heterostrophic subulitids with a sinistral larval shell. Reevalution of the traditional character "columellar fold" shows that the fold in Ordovician subulitids is distinct from that of late Paleozoic soleniscids. Several post-Paleozoic clades have been linked with the subulitoids. Protoconch characters show that most genera became extinct at or before the end-Permian crisis and that there are only a few examples of possible survivors.

N1 - Last updated - 2012-06-07 ER - TY - JOUR T1 - A cathodoluminescence record of fluid-rock interactions in low-T, K-metasomatized volcanic rocks, Western USA AN - 52276670; 2001-007024 AB - K-metasomatism at low-T conditions is widespread in volcanic rocks from various tectonic settings. It produces drastic changes in rock chemistry and mineralogy, but the effects are subtle, both in the field and with conventional petrography. Understanding the effects of low-T K-metasomatism of volcanic rocks is needed to determine the extent to which the tectonomagmatic settings of metamorphosed volcanic rocks can be constrained, and to predict the potential fluid yield of such rocks during metamorphism. Cathodoluminescence (CL) petrography and optical spectroscopy easily and rapidly characterize K-metasomatic features, and readily discriminate igneous, alteration and overprinted metamorphic textures. To determine the mechanisms of low-T, K-metasomatism, rocks altered in three settings: (1) caldera collapse (Creede, CO); (2) playa-derived saline groundwaters (Socorro, NM); and (3) the upper plate of a detachment fault (Harcuvar Mtns., AZ) are being studied by CL, conventional petrography, and various geochemical techniques. Whole-rock K/Na, Rb/Sr, and Fe2O3/FeO increase with the intensity of K-metasomatism, and oxygen isotope values change. Accompanying these effects, faintly brown-luminescent Or>97 adularia first replaces green-to-yellow-luminescent plagioclase phenocrysts and groundmass, and then blue-luminescent, Or40-70 sanidine phenocrysts. The adularia replacement is typically patchy, but may also preferentially occupy cleavages, original igneous zoning features, fractures, and twin lamellae. CL also differs among generations of quartz: igneous phenocrysts typically display purple CL, whereas low-T quartz luminesces red and commonly occurs as overgrowths on quartz and feldspar phenocrysts, as well as the groundmass. Late hydrothermal silica in agate-chalcedony veins commonly luminesces yellow. Yellow-luminescent hydrothermal feldspar, which is not visible in BSE imaging or conventional petrography, is associated with hydrofracture features that overprint low-T K-metasomatic features from Socorro. Some of these samples have five CL-distinct types of feldspar. Groundmass quartz from all three localities has recrystallized around altered phenocrysts. Its luminescence may record fluid pathways through the rocks.Low-T alteration features survive low-grade metamorphism. Metatuffs from the Inyo Mtns., CA, were K-metasomatized before contact metamorphism to the albite-epidote-hornfels facies. Parts of relict feldspar phenocryst grains retain igneous compositions, yet these grains also contain brown- and/or blue-luminescent Or>95 feldspar.

These studies were based on global, family-level compilations of body-fossil data that indicated no deviation from background rates of extinction. By contrast recent palynological and megafloral evidence demonstrate a major extinction of plant taxa at the K/T boundary. To test these opposite conclusions, we examined insect-mediated plant damage on 6000 leaves in a succession of 78 floras from the Williston Basin of southwestern North Dakota, spanning a 2.0 m. y. interval of the Late Maastrichtian Hell Creek Formation and earliest Puercan Ludlow Member of the Fort Union Formation. This interval comprises four megafloral zones constrained by magnetostratigraphy, vertebrate biostratigraphy, and a laterally extensive K/T boundary defined by palynomorph extinction coincidence with iridium and shocked quartz anomalies. All characterizable leaf hosts from these floras have been assigned to morphotypes and/or Linnean identifications, providing explicit recognition of plant hosts. We identified 42 types of insect damage, representing herbivory from five functional feeding groups: external foliage feeders, leaf miners, gallers and piercer-and-suckers. For the Hell Creek Flora 41 types of damage were identified, including conspicuous examples of galls and scales on primary veins, serpentine mines, and diagnostic slot-hole feeding, each occurring monospecifically and abundantly on separate species of Lauraceae, Platanaceae and Cannabaceae. For the Fort Union flora, 17 types of damage were identified, abundance was significantly lower, and the associations were more generalized, lacking host specificity. These data demonstrate that at local scales insect herbivory suffered during the K/T boundary, with no evidence of subsequent recovery. Levels of herbivore diversity remained depressed until pronounced vegetational shifts in the Western Interior during the Early Cenozoic Thermal Maximum of latest Paleocene to early Eocene.

Ocean Drilling Program Leg 178 (February-April 1998) drilled two sites (1097, 1103) through the outer Antarctic Peninsula Pacific continental shelf into strata no older than late Miocene or early Pliocene (<4.6 Ma). Site 1097 lies on the outer shelf and reached a maximum depth drilled of 420 m below the sea floor (mbsf). Strata consist of thick intervals of massive diamictite, containing large amounts of reworked and abraded marine microfauna, interpreted as tills produced by subglacial re-working of marine sediments. Tills are separated by bioturbated muds with dropstones and contain a diverse in situ fauna. The sedimentary record at Site 1097 is consistent with aggradation of a "topset" by till deposition alternating with open marine sedimentation. Site 1103, close to the shelf edge, reached a depth of 363 mbsf through massive and chaotically-stratified diamictites with graded siltstones consistent with deposition on a slope "foreset" and progradation of the continental slope by deposition of debrites and turbidites.

Such events, originating outside the Earth and wreaking instantaneous devastation on the lithosphere and biosphere, violate every tenet of the uniformitarian principle as it has been understood for the past two hundred years. James Hutton and Charles Lyell envisioned the Earth as an endlessly recycling system, subject only to processes intrinsic to it, and operating at rates that may be observed today. In recent years, some investigators have interpreted the record of impacts imaged on all the rocky bodies of the Solar System as a validation of uniformitarianism. Others have cited the same record in support of "neocatastrophism". The final bankruptcy of these two terms was illustrated in 1997 at the Hutton-Lyell Bicentenary symposia in Britain. One speaker, L. G. Wilson, declared that Lyell's uniformitarian views have been fully vindicated--regardless of impact events; another, M. R. Leeder, argued that Lyell was not a strict anti-catastrophist and that he probably would enjoy a hearty laugh if he were to hear our modern view of him as the "father of uniformitarianism". Still another speaker, J. Knill, dismissed uniformitarianism as a misnomer--much beloved of university examiners--which implies that the rates and nature of geological processes remain unchanged through time. He argued that, on the contrary, the current human influence on climate and the environment has all the hallmarks of a phase which, if found in the geological record, might be interpreted as cataclysmic. With so extreme a range of defining views, uniformitarianism clearly is a concept that has lost its usefulness. A sound basis always was lacking for the assumptions that present rates of change should serve as the standard for those of the past, and that causes of change are limited to the Earth's own systems. Both views have been demolished by impacts from space. Our science will be better served if we study and interpret geological phenomena without reference to such outdated old catchwords.

Our study reveals that extinction of the deep-dwelling planktic foraminifer genus Rotalipora and Globigerinelloides bentonensis occurs at a level where middle bathyal waters increased from 15 to 19 degrees C, which is warmer than any other time during the Cretaceous and Cenozoic. The intermediate water warming may have caused a breakdown in the vertical structure of the water column, and could explain the extinction of the deeper dwelling planktic taxa. This warming event has also been identified from oxygen isotopic records of deep-sea planktic foraminifera in the southern high latitudes and is consistent with paleontological evidence for extreme warmth in the Arctic. On the other hand, sea surface temperature estimates based on planktic foraminiferal d18O values from Site 1050 (corrected for the modern day salinity gradient) remain steady throughout the CTBI, varying between 23 to 26 degrees C, which is within the range of subtropical SSTs today. Co-occurrence at Site 1050 of volcaniclastic sediments with the warmest benthic foraminiferal paleotemperatures supports previous speculation that there was a substantial increase in global volcanism and atmospheric pCO2 outgassing across the CTBI. If increased pCO2 was the primary mechanism driving the middle Cretaceous supergreenhouse then we must explain how heat was transported from the tropics to the poles with enough efficiency to maintain a latitudinal thermal gradient profile that was nearly flat.

Benson et al. (1985), using 1-Myr sampling intervals, documented the global deep-sea ostracode response to this transition to be decreased abundance, increased diversity, and decreased provinciality. To better understand the tempo and mode of ostracode response in the Southern Ocean, an important locale for thermohaline circulation, high-resolution (20-50 kyr) faunal analyses were conducted at ODP Sites 744 (Kerguelen Plateau) and 689 (Maud Rise). The 2.5 Myr study interval brackets the major positive step in oxygen isotopes (Oi-1; approximately 34.4 Ma), which records significant cryospheric growth and deep-water cooling.At Site 744, ostracode abundance and rarefied richness is greatest prior to Oi-1, decreases rapidly at its onset, and then increases towards initial values through two Oi-1 relative maxima. In contrast, Site 689 abundance and rarefied richness are lower overall, with relative maxima from approximately 34.5-34.0 Mya, during the first Oi-1 relative maxima, and after the second Oi-1 relative maxima. Site 744 evenness is generally lower and less variable than at Site 689, but increases during Oi-1. Cluster and principal component analyses demonstrate that Site 744 faunal changes were transient, with pre- and post-Oi-1 faunas slightly more similar to one another than to the Oi-1 fauna, while at Site 689 the Oi-1 faunal shift persisted through the remainder of the study interval. At both sites, Cytherella, Bairdoppilata, and Cytherelloidea disappear at the onset of Oi-1, except for rare, single occurrences. Unlike deposit-feeding podocopid taxa, these filter-feeding platycopids can thrive under dysoxic conditions through efficient water circulation over the ventral body surface. Actinocythereis and Trachyleberis are common throughout Site 744, but at Site 689 are absent after Oi-1. Bradleya is also common throughout Site 744, but at Site 689 is present after Oi-1. Henryhowella, predominant in modern Antarctic Intermediate Water, significantly increases in abundance at Site 744 after Oi-1. These faunal changes do not correspond with surface productivity (i.e., biogenic opal) and likely reflect synchronous changes from warmer, lower-oxygen to cooler, higher-oxygen bottom water conditions.

Molecular analyses suggest that these groups, along with fungi and the lineage leading to metazoa, diverged during a pre-Neoprotoerozoic radiation. This constrains the Neoproterozoic the snowball earth hypothesis. A snowball earth would have imposed a series of strong environmental filters on the biota, including: (1) a gradual decline in atmospheric carbon dioxide and biotic productivity with the onset of global glaciation; (2) sharply limited solar illumination in the oceans and a drop in oceanic pH with the onset of glaciation; finally, (3) as the release of volcanic CO (sub 2) induced sufficient global warming and a rapid collapse of glacial conditions, marine waters shifted rapidly from acidic to highly alkaline conditions, possibly with the development of a transient freshwater surface layer, followed by a gradual return to normal marine conditions. Each of these environmental insults imposes differing selective regimes on the biota, and was likely associated with drops in biodiversity. The estimated duration of snowball glaciations (4-30 myr) raises the possibility that deleterious mutations may drive populations extinct, effectively establishing minimal lower bounds for effective population sizes during the snowball. Simulations indicate that in a constant selective environment effective population sizes of about 500 would have been sufficient, which are greatly exceeded by most unicellular lineages (assuming that minimal photosynthetic activity occurred). However, for macroscopic algae or early metazoans, effective population sizes would have been a more important constraint. If the selection coefficient had an exponential distribution (i.e., a variable selective environment) effective population sizes, rapidly climb into the thousands to tens of thousands (depending on generation time). Thus the environmental filters and random variation in population size may have been more important limits on population persistence. Evidence from heat shock proteins and other studies demonstrate the potential for rapid evolutionary response to the environmental effects of a snowball earth, and for evolutionary diversification during the post-glacial recoveries.

In the meteorite ALH84001, bacteria are presumed to have mediated the formation of approximately 150-micron carbonate discs with complex triple-rimmed structures. In the Nakhla meteorite, the authors have observed clays that host iron-silicate spheres with diameters of several microns, and they have identified these assemblages as petrified bacterial mats. Fossils of coccoidal, unicellular bacteria have been firmly documented in rocks of Archean age and younger, but their unambiguous assignation is rooted in their preservation as organic films, typically embedded within a siliceous matrix. Even in instances when organic material is present, the identification of spherical structures as fossils must comply with strict guidelines that have been developed over several decades (e.g., Hofmann, 1972; Cloud, 1976, 1983; Schopf and Walter, 1980, 1983; Buick 1990). These guidelines specifically exclude from consideration isolated spherical structures that are non-kerogenous. Based on our extensive studies of inorganic microspheres in several Precambrian BIFs, the Lafayette SNC meteorite, and certain botryoidal materials, we concur that spherical microtextures are insufficient evidence to adduce biogenic formation. This assessment holds even when the structures are of the appropriate dimension, layered architecture, and low-temperature mineralogy for a presumed bacterial genesis. Using electron imaging, diffraction, and microanalysis, we have documented extreme complexity in microspheres of certain abiogenic origin, including rhythmic oscillations in crystal size and twin boundary distribution, compositional banding, and systematic variations in crystal orientation. Understandably, some of these structures have been mistaken for fossils, but we argue that a healthy respect for the natural self-organizational capabilities in non-equilibrium inorganic systems should prevent inferences of biogenicity in the absence of additional evidence.

Considerable attention has been devoted to diversity and extinction, but comprehensive studies of origination have lagged behind. While meaningful global patterns of origination have been documented, their decomposition into regularities and contingencies of individual groups and environments allows for additional insights, since conflicting signals may exist. Such decomposition is especially useful in characterizing origination in terms of the relationship of abiotic and biotic factors to environmental context and taxonomic membership.The dynamics of origination in the fossil record of three marine groups (molluscs, echinoderms and fishes) and three terrestrial groups (mammals, insects and plants) is analyzed. Patterns at two levels are derived: (a) at the level of lineages, approximated by either families or genera; and (b) at the level of putative major innovations, approximated by either orders or character complexes (the latter were used for angiosperms). The data correspond to compilations from global synoptic compendia of stratigraphic ranges, including Sepkoski's Compendium of Fossil Marine Animal Families and unpublished genus-level database, the Fossil Record 2, and the Compendium of Fossil Insect Families. The original data are culled to minimize taxonomic and sampling biases, with removal of single-stage, incertae sedis, problematic and poor preservation taxa. Four hypotheses are tested to statistically assess possible controls on the origination process: (1) secular decline in lineage origination; (2) secular decline in evolutionary innovation; (3) diversity dependence of lineage origination; (4) self-organized criticality of lineage origination. A decline in lineage origination and in the production of major innovations is present in all groups, suggesting controls that transcend the land-sea distinction. The relationship between diversity and origination appears to be strong in the sea and weak on land, a difference that might imply environment-specific controls. Mixed support for a logistic dynamics of origination is found. Finally, there is no general support for a self-organized critical behavior of origination, with the predictions appearing to hold only in insects and pteridophytes/gymnosperms.

During the Maastrichtian the Blake Nose was located at a paleolatitude of approximately 30 degrees N, near the western edge of the Tethys; paleodepth is estimated at 1-2 km. Shallow burial increases the probability that depositional geochemical signals are preserved. The hemipelagic interval studied is composed dominantly of nannofossil chalk (80 to 95% CaCO3) with a significant amount of terrigenous material and abundant well-preserved foraminifera. Shipboard data shows approximately 50 cm thick cyclic alternations in color and magnetic susceptibility that are thought to reflect the approximately 20 kyr precessional cycle. Because the time scale is short, the location does not change, and sedimentological features repeat; paleoceanographic factors can be isolated. Causally linked changes should be correlated from cycle to cycle. Across several cycles, we found variations in stables isotopes (oxygen up to 0.8 and carbon up to 0.6), the relative abundance of planktic foraminiferal species, the mineralogy of acid-insoluble residues, and elemental abundances that all match lithologic cycles. High planktic oxygen values are correlated with high planktic but low benthic carbon values indicating cooler and/or more saline surface waters were associated with higher productivity and vice versa. High productivity intervals are also characterized by high Ca concentrations, enrichment in feldspar, and increases in the relative abundance of Heterohelix spp., Globigerinelloides spp., and Laeviheterohelix glabrans. Conversely, low productivity intervals have high Fe concentrations, enrichment in quartz and clay minerals, and relative increases in Globotruncana spp. and Pseudoguembelina spp. These correlations suggest linkage among climate, continental weathering, ocean productivity, and foraminiferal communities on geologically short time scales. Determining what processes are driving productivity cycles (e.g., continental fluxes, upwelling) is not simple, but foraminiferal populations seem to respond in a systematic fashion which will allow better interpretation of foraminiferal assemblages elsewhere.

To test these claims, we made nearly 375 new collections containing approximately 160,000 shells and 1,000 genera and subgenera of recent and fossil mollusks. Thirty replicate dredge samples from each side of the Isthmus of Panama yielded similar numbers of genera and subgenera in both oceans but much larger numbers of shells in the TEP. Thus the slopes of cumulative diversity curves and the Shannon-Weiner index of diversity are much higher in the TWA than the TEP. Diversity also increased greatly in the TWA at the end of the Pliocene. This increase is not an artifact of mixing recent and fossil data since Pleistocene diversity in the TWA is much higher than in the Pliocene or Late Miocene, or even in the recent TEP. The reason for these contrary results is sampling bias related to abundance of shells and productivity. Diversity is higher in lower productivity environments such as the recent and Pleistocene TWA, but the shells are rarer and harder to find than in higher productivity environments like the recent TEP and Neogene TWA. Failure to consider this numerical sampling bias resulted in the wrong explanations for patterns that do not exist.

These stromatolites are composed primarily of fine grained carbonate sand that is trapped and bound by filamentous cyanobacteria (Schizothrix sp.). Periodic introduction of coccoid endolithic cyanobacteria, Solentia sp., results in formation of lithified horizons, 200 to 1000 mu m thick. We used SEM and petrographic analyses to examine both naturally occurring lithified layers dominated by endoliths and fused oolitic crusts generated in the laboratory by activity of endolithic cyanobacteria (Solentia sp.). Fused grain crusts consist of micritized grains that are welded together at point contacts. Micritization results from extensive microboring and rapid (days to weeks) carbonate precipitation within the bore holes. This precipitation appears to occur concurrently with further endolithic activity within the grain. Infilling of bore holes that cross from one grain to another at point contacts results in grain welding. Thus, while microboring destroys original grain textures, at the same time the endolith activity plays a constructional role in stromatolite growth by forming lithified layers of welded grains. These framework structures help to stabilize and preserve the stromatolite deposits.

In order to mine this information we analyzed phylogenetic relationships among Tryonia species based on a partial sequence of the mitochondrial COI gene. Maximum parsimony analysis of these data yielded a phylogenetic tree which included two large western sub-clades having a sister-group relationship. Phylogenetic structure of one of these sub-clades is congruent with vicariant events associated with late Neogene history of the lower Colorado River drainage. The other sub-clade mirrors development of the modern Rio Grande rift and inception of modern topography in the southwestern Great Basin during the late Neogene. Both sub-clades are represented in the Amargosa River basin, which is interpreted as a biotic and geologic composite, and whose assembly is attributed to the complex geological history of the Death Valley region.

The traditional explanation for this pattern has been to refer evolution to extrabasinal areas, where preservation of transitional stages was unlikely. Although never discredited, the model has fallen into disfavor as ad hoc. Several observations suggest that it may merit reconsideration. (1) The Lazarus reappearance of rare xeromorphic tropical lineages during the Late Paleozoic suggests xeric refugia in non-depositional areas; examples are the Mississippian taxa Sphenopteridium and Archaeocalamites, which reappear in Late Pennsylvanian floras rich in other xeromorphic plants. (2) The appearance of derived xeromorphic seed plants as transported fragmentary debris in otherwise typical lowland-wetland assemblages indicates unsampled vegetation proximate to wetland basins; the earliest conifers, for example, occur as charcoalified debris in Middle Pennsylvanian floras, and only later in Late Pennsylvanian floras dominated by derived seed plants, including ginkgophytes and callipterids. (3) Distinct vegetation occurs sporadically in basins in association with evidence of regional dryness; such floras are at first rare and of low diversity in the Late Pennsylvanian and become common and more species rich in the Early Permian. This pattern is emphasized by the recent discovery of a yet more distinct latest Early Permian flora dominated by taxa typical of the Late Permian and mid-Mesozoic. (4) Wetland basinal floras are ecologically and evolutionarily conservative through most of the Paleozoic; most evolutionary diversification in the wetlands is within established generic lineages, part of vegetation that persists until disrupted by physical environmental changes. (5) Compositionally distinct Late Paleozoic floras are temporally intercalated (with little mixing) through transition intervals. These patterns suggest that novel taxa of successively younger floras originate in physically stressful habitats (where competition from incumbents is minimal). Younger floras replace rather than displace the older floras in depositional basins during times of physical environmental change. In this model both extrabasinal evolution of novel forms and extrabasinal to basinal ecological replacement are made possible by the suppression of resource competition by physical factors.

Several hundred specimens occur on at least three stratigraphic levels within 10 meters of interbedded sandstones and siltstones. The specimens are preserved in positive relief on the tops of centimeter to decimeter-thick flat laminated to hummocky cross-stratified fine quartzitic sandstones. The exceptional, three-dimensional preservation results from burial by thin mudstone interbeds separating the sandstone tops from the erosive base of the immediately overlying sandstone body. Most specimens are 1.5 to 5 cm in maximum diameter, with an low outer ring, a domal central mass and a central dimple; others have less relief, and no differentiation between the outer ring and central mass. The size of the central dimple commonly scales to overall size. The largest specimens are 1.5 cm high. A fluid or water-escape origin for the structures is rejected by a lack of disruption to underlying sandstone laminae and a lack of mud partings to form impermeable barriers and hence interstitial pore fluid pressure differences. Abutting specimens commonly show distinct, deformed boundaries, and the cohesive nature of the specimens is demonstrated by a single, inverted specimen which preserves all of the characteristic morphology of the others. Assigning these specimens to previously described material is difficult. Aspidella is a circular to elliptical form previously recorded only from Avalon (Newfoundland) and possibly Siberia but contains well-defined, central radiating structures. Irridinitus from Russia and Canada is most similar, but has radiating rugae which are not found on the Namibian specimens. Although the exact age of the unit remains uncertain, the rocks are older than the 548 Ma Kuibis Subgroup of the Nama Group and post-date the youngest recorded Neoproterozoic glaciogenic deposits of the Kalihari Craton.

In most arid settings, the deltaic landscape has been markedly altered by ever-increasing anthropogenic disruption of the fluvial system. Nile and Rio Grande deltas provide noteworthy parallels with regards to such change. Neolithic settlements formed within 500 years of Nile delta formation, with a good record of water discharge since Dynastic time. Although increasingly harnessed during the two past millennia, Nile delta experienced greatest modification between mid-19th and mid-20th century, i.e. barrages, Low (1902) and High Dams (1964) at Aswan, and a network of >10,000 km of irrigation channels across the delta plain. Fresh water no longer flows to the sea from the two distributary mouths. The 40 million living on the delta are increasingly dependent on fresh water much of which is now polluted by input of municipal, agricultural and industrial wastes. Ongoing construction of two major canal projects, to divert >10% of an already decreased Nile discharge to adjacent desert areas, will further seriously impact the Nile delta, a system that has now attained its destruction phase. Human activity in the Rio Grande delta during the past 2000 years is of similar, but smaller, scale. Water control began in earnest with diversion channels only late in the 19th century, followed by 4 dam-reservoir systems in early to mid-20th century. The northern (Texas) delta plain is more modified than the southern (Mexico) side. Most water is diverted for agriculture and municipal use in >1500 km of irrigation and drainage canals and pond systems in the Texas sector, and now only a much reduced Rio Grande discharge reaches the Gulf of Mexico. Will the Rio Grande delta be allowed to degrade and reach its destruction phase in comparable fashion as the Nile?

Do the nature and frequency of volcanic eruptions vary with seasonal changes? As a preliminary study, Arenal Volcano is an ideal subject because it is in nearly constant eruption. Costa Rica's weather near the volcano is highlighted by a dry season and wet season, though there is substantial rainfall year round. During the rainy season, rainfall may exceed thirty inches a month. The high precipitation at Arenal, and subsequent percolation and penetration of the magma chamber walls by rainwater can conceivably lead to a marked increase in pyroclastic activity. Seismic data from eruptions of Arenal from 1993 to 1999 have been examined in search of such seasonal patterns. Shape and structure of erupted ash are also potential indicators of a water-rich magmatic environment. Scanning electron microscope examination of tephra reveal angularity which may indicate a phreatic component in some explosive eruptions. In preliminary evaluations, however, the seismic data do not show a cyclic increase in pyroclastic activity during the rainy season, which spans May to September. Thus, seasonal rainfall appears to have little effect on the intensity of pyroclastic activity. The layers of tephra and lava flows which make up the volcano may be impervious to rainwater percolation or may even out the flow rate to the hot rocks that surround the magma chamber.

Coarse breccia with shatter coning and microbreccia with moderately shocked fragments containing maskelynite were found in drill holes through the crater floor. Trenches on the rim yield strongly shocked fragments in which plagioclase has melted and vesiculated, and bombs and spherules of homogeneous rock melt. As the only known terrestrial impact crater in basalt, Lonar Crater provides unique opportunities for comparison with lunar craters. In particular, microbreccias and glass spherules from Lonar Crater have close analogs among the Apollo specimens.

Data from 5 drillholes, a gravity network, and field mapping are used to reconstruct its original dimensions, delineate the nature of the pre-impact target rocks, and interpret the emplacement mode of the ejecta. Our estimates of the pre-erosion dimensions are: average diameter of 1710 m; average rim height of 40 m (30-35 m of rim rock uplift, 5-10 m of ejected debris); depth of 230-245 m (from rim crest to crater floor). A continuous ejecta blanket extends over an average of 1410 m beyond the pre-erosion rim crest. The target rock column at Lonar consists of one or more layers of weathered, soft basalt capped by fresh, dense flows. Plastic deformation and/or compaction of this lower, incompetent material probably absorbed much of the energy normally available in the cratering process for rim rock uplift. A fluidized debris surge was the dominant mechanism of ejecta transportation and deposition at Lonar. In this aspect, Lonar should be a good analog for the "fluidized craters" of Mars.

Consequently, changes of relative sea-level that account for both eustatic sea level and land motion are subtle and generally difficult to measure. This study evaluates the value of pools and other anthropogenic rock-cut features used to measure changes of sea level during the late Holocene. A number of these depressions, originally formed to retain fish and for other purposes, still function at present sea level. Most rock-hewn pools and channels on the Israeli margin have been dated to Roman, Byzantine and Crusader periods, usually through indirect association with archaeological sites and other structures in the vicinity. In fact only a few of these features, such as the piscina at Caesarea with affixed mosaics, are accurately dated. It is proposed here that some rock-cut features on broad flat platforms, or trottoirs, at elevations close to present sea level, were formed in more recent time, possibly in association with quarry operations and removal of coastal rock material for construction during the past few centuries. Unless a rock-cut feature can be reliably dated, it should not be used determine sea level or land motion on this geologically complex margin.

Tyto neddi is the first extinct species of barn owl known from the Lesser Antilles. It appears to be most closely related to the several large, extinct species of Tyto known from late Quaternary cave deposits in the Greater Antilles and Bahamas. By far, the most abundantly represented species of vertebrate at the type locality of T. neddi is a large, extinct oryzomyine rodent (genus and species undescribed) that probably was the primary prey item of T. neddi. A single pedal phalanx from the type locality of T. neddi represents a much smaller species of Tyto that is the size of the extant T. alba (Scopoli). Bones of the Burrowing Owl, Athene (Speotyto) cunicularia (Molina), also occur commonly in Barbudan caves. Thus Barbuda, where no species of owl occurs today, once supported at least three species.

The shallow solar incidence angle of the MOC image indicates that the dunes are very low-relief features; shadow lengths limit the dune heights to 10 cm to <2 m thickness. The dunes may not experience sand-driving winds due to a pervasive dust cover that is difficult to remobilize and remove without the aid of actively saltating sand. It is important to look for additional opportunities to test whether dunes elsewhere on Mars, particularly outside of low thermal inertia regions, show documented movement relative to the Viking era (there are 527 cloud- or haze-free Viking images of <10 m/pixel resolution, distributed between 50 degrees N and 45 degrees S).

We analyzed Magellan and Arecibo data for these regions to study the roughness of the surface, lower radar-backscatter areas at the highest elevations, and possible causes for areas of anomalous behavior in Maxwell Montes. Arecibo data show that circular and linear radar polarization ratios rise with decreasing emissivity and increasing Fresnel reflectivity, supporting the hypothesis that surface scattering dominates the return from the highlands. The maximum values of these polarization ratios are consistent with a significant component of multiple-bounce scattering. We calibrated the Arecibo backscatter values using areas of overlap with Magellan coverage, and found that the echo at high incidence angles (up to 70 degrees ) from the highlands is lower than expected for a predominantly diffuse scattering regime. This behavior may be due to geometric effects in multiple scattering from surface rocks, but further modeling is required. Areas of lower radar backscatter above an upper critical elevation are found to be generally consistent across the equatorial highlands, with the shift in microwave properties occurring over as little as 500 m of elevation. These surfaces are not simply characterized, however, by the absence of a highly reflective component. Surface morphology and radar-scattering properties suggest that a mantling deposit forms at the highest elevations, most likely by in situ erosion of the original rock. In Ovda Regio, this process mantles or has removed surface festoon structure at the 1- to 10-m scale, implying a significant depth for the weathered layer. Similar radar-dark areas occur in Maxwell Montes but are apparently unrelated to the current topography of the region. Possible reasons for these observations include mass wasting from areas of steep slopes, compositional or age differences within the montes, vertical tectonic shifts of relict contacts, local topographic effects on surface temperature, or errors in the Magellan topography data in the rugged terrain. While there is evidence for some of these effects in the existing data, no single model at present appears to satisfy all occurrences of high-altitude, radar-dark terrain. New measurements of the surface and lower atmosphere chemistry of Venus are needed to further refine these conclusions. Copyright 1999 by the American Geophysical Union.

All watersheds were equipped with V-notch weirs and volume-integrating, flow-proportional samplers. Spot samples were also taken for analysis of TSS concentrations and the composition of dissolved and particulate nutrients at known water discharge rates. Interannual variations in annual and seasonal precipitation during this study spanned approximately the range of 160-yr weather records in the vicinity. Mean annual TSS fluxes were 263, 546, 134, and 92 kg ha super(-1) for the area-weighted mean of the overall Rhode River watershed, and for subwatersheds that were primarily-cropland, completely forested, and grazed, respectively. TSS fluxes were highest in the summer, followed by spring, winter, and fall. Regressions of TSS flux vs precipitation were used to calculate TSS fluxes for seasons and years with average, above and below the average precipitation. TSS flux from the Rhode River watershed was 12-fold higher in very wet years than in very dry years and 271-fold higher in very wet summers than in very dry summers. At base flow, TSS had high nutrient content, but as flow rates increased TSS nutrient content rapidly declined. At base flow, most of the total-P, TPi, TKN, and organic-C was in the dissolved phase, while at higher flows, most of these nutrients were in the TSS phase.

I separated the process that leads to settlement of a drifting particle into three stages: (1) initial contact with a substrate, (2) attachment, and (3) settlement sensu stricto. I used physical principles (height above the bed, sinking rate, current speed profile) to predict time until contact (stage 1). I compared these predictions with empirical measurements of settlement of individual black fly larvae (Simulium vittatum) in a laboratory flume. I developed models from empirical data for stages 2 and 3. Each of these models is individual-based and predicts the fate of a single individual. To obtain a population level prediction, models for the three stages were combined and used to simulate the settlement of a group of black fly larvae. The predictions of this simulation were qualitatively similar to population level data from the literature particularly after the incorporation of channel-wide spatial heterogeneity in current speed. The effect of flow heterogeneity on the model agrees with previous work on the lateral transport of stream invertebrates during drift events showing that many organisms settle preferentially in slower areas. By using proximal principles, the approach used in this study brings into focus basic parameters and processes that influence settlement at the scale of the organisms. It also provides a null hypothesis against which to study the effect of local flow heterogeneity on the settlement of stream invertebrates and the capacity of organisms to actively influence settlement. Water currents in streams and rivers commonly transport large numbers of organisms. Consequently, hydrodynamic factors that favor or hamper the settlement of these organisms can potentially influence distributions and abundance. Moreover, if settlement probabilities vary with flow characteristics, this can in turn influence foraging strategies that rely on fluid-mediated dispersal.

For North America alone, hundreds of marine and estuarine species are known to have established non-native populations, resulting from human-mediated transfer beyond their historical ranges. Scores to hundreds of marine invasions are reported for many other global regions as well. Furthermore, recent work has begun to measure the effects of marine invasions on population, community, and ecosystem processes, underscoring both their ecological and economic significance. Despite recent advances in describing the scope and consequences of marine invasions, many conspicuous gaps exist in our knowledge in both aspects. For example, the ecological impacts of most marine invasions remain unknown. Perhaps more surprising, the spatial and temporal patterns of invasion remain poorly resolved, due to many confounding factors in the quantity and quality of existing data. These gaps in knowledge present many challenges for both (a) understanding invasion processes and (b) developing effective management strategies to reduce the risks associated with invasions in marine systems. Here, I discuss briefly the state of knowledge for marine invasion patterns of North America, highlighting general patterns and limitations. In addition, I review next steps to address these limitations. This abstract is intended to provide only a short summary of much more comprehensive reviews (as cited below). I have also excluded further discussion of invasion impacts, which are reviewed by others in this volume. JF - Marine Bioinvasions.

A primary charge of the Clearinghouse is to measure patterns of ballast water delivery and exchange across commercial shipping ports throughout the United States. The Clearinghouse has implemented the National Ballast Survey (NABS) to investigate these patterns. NABS is designed explicitly to measure patterns of ballast water delivery and management (primarily ballast water exchange) according to vessel class by geographic region and season of arrival. Additionally, among-year changes in ballast water management by vessel class and geographic region will also be possible. An important aspect of NABS is the ability to assess accuracy of data through use of multiple, independent data sources. In 2001, data from the Clearinghouse will be analyzed and reported to the U.S. Congress and U.S. Coast Guard for review. JF - Marine Bioinvasions.

The biodiversity perspective suggested that ongoing wetland protection policies were not working because restored or created wetlands were often different from natural wetlands. Wetland mitigation projects often resulted in the exchange of one type of wetland for another resulting in a loss of wetland functions at the landscape level. A lack of protection for dry-end wetlands was evident. From an ecological perspective, dry-end wetlands and riparian wetlands associated with first order streams may be the most important landscape elements by supporting higher biodiversity. The present failings of projects is due to the lack of ecologically sound wetland assessments. There are 65 references.

Increased carbon dioxide has, however, markedly increased plant growth rates as inferred from numerous laboratory and field experiments. There is no clear evidence, nor unique attribution, of the global effects of anthropogenic CO sub(2) on climate. Meaningful integrated assessments of the environmental impacts of anthropogenic CO sub(2) are not yet possible because model estimates of global and regional climate changes on interannual, decadal and centennial timescales remain highly uncertain.

Barbados, an outlying island in the Lesser Antilles, was formed approximately 700,000 YBP by tectonic uplift and was then colonized by birds via natural invasion from the much older volcanic islands in the main Lesser Antillean arc. We investigated the timing and sources of the avian invasion of Barbados by determining levels of mitochondrial DNA (mtDNA) divergence between populations of eight bird species from Barbados and those on the nearby putative source islands of St. Lucia and St. Vincent. Although all Barbados populations appeared to be young relative to the geological age of the island, we found differences among species in their inferred times of colonization and we identified at least two sources of immigrants to Barbados. In contrast to these historical differences across species and populations, our characterization of the mitochondrial genotypes of 231 individual birds suggests that each island population represents the descendants of a single founding maternal lineage. Considered in concert, the results of this molecular survey indicate that the Barbados bird community is composed of species with different invasion histories, which in turn suggests that the island's community composition has changed repeatedly over its 700,000 year history.

The purpose of the study was to evaluate the utility of using systematic collections in identifying areas with a high priority for conservation. A biodiversity database and a gazetteer were assembled and interpreted primarily through the use of maps generated in ARC/INFO and ArcView. The data were examined to determine coverage and completeness, and while in general the results support a continued use of the methodology for making informed decisions in conservation related issues, several recommendations are offered in order to enhance the data. The primary use of the results of this study is in the identification of areas of interest for conservation and in the location of eleven areas covering most ecoregions in Guyana that are in need of additional study. The eleven areas have been chosen to avoid areas that are already allocated to logging and mining concessions or Amerindian lands. While it is true that this study would benefit from additional data and further analysis of those data, it is also true that decisions concerning areas for conservation in Guyana are being made in the near future, and if any data are to be used in this process, it will be those data presented in this paper.

We manipulated four factors that could influence individual recognition cues: the mother queen, the environment during the immature stage, the environment during the early adult stage, and worker age. We also simulated the action of natural enemies on colonies tested for discrimination of such worker characteristics. All factors that we tested affected responses of the discriminating workers, which could recognize sisters, nieces and unrelated workers. Previous exposure of unrelated callow bees to the odor of the host nest greatly increased chances of acceptance by the host colony. Probability of acceptance decreased, however, with increasing age of introduced bees or increasing disturbance of the host colony. These complexities in patterns of nestmate recognition and nest defense are adequately explained from the standpoint of inclusive fitness of the discriminating workers.

Individual Behavior Profiles and Their Relationship to Breeding Success AN - 17248965; 4536987 AB - This is the first part of a multi-zoo study to analyze the effects of captive environments on black rhinoceros (Diceros bicornis) behavior, breeding success, and well-being. We estimated the reliability and validity of a standardized method of cross-institutional assessment of the behavior of individual rhinoceros. In 1994 and 1995, we asked zookeepers at 19 zoos to rate their black rhinoceros (a total of 60 animals) on 52 behavior elements using a questionnaire. At 14 zoos, at least two keepers rated all the black rhinoceros at their zoo. We used average differences in their ratings of the 52 behavior elements to determine the most reliably rated behavior elements. Fourteen elements were retained for further analysis. Based on their inter-correlations, we grouped these 14 behaviors into six behavior traits: olfactory behaviors, chasing/stereotypy/mouthing, friendly to keeper, fearful, patrolling and dominant (to conspecifics). A behavior profile of each animal consisted of scores on these six traits that were the sum of the primary keeper's ratings for each element in the group. To test the validity of these profiles, we compared scores on the six traits to the behavior of each rhinoceros during a standardized test of reactivity to a novel object and a novel conspecific scent. Tests were videotaped and analyzed by one researcher. Frequencies and durations of behaviors observed during the tests were correlated with scores on all six rated behavior traits. Scores on friendly to keeper, dominant, and olfactory behaviors described differences between black rhinoceros of captive/wild caught origin, age,and sex, respectively. Among successfully breeding males, scores on dominant and olfactory behaviors were negatively correlated with reproductive success, as was chasing/stereotypy/mouthing for females. To test the repeatability of these results, during 1996-1997, we used a modified questionnaire to re-survey 70 black rhinoceros at 24 zoos. Results of the second survey were also similar to those of the first with respect to the behaviors that distinguish rhinoceros of different origin, age, sex, and reproductive success. We conclude that ratings by keepers of behavior and temperament attributes can be used as reliable and valid cross-institutional descriptions of individual differences between black rhinoceros.

These estimates are based on the assumption that geographic isolation occurred nearly simultaneously for most taxa, when connections between the Caribbean and eastern Pacific closed approximately three million years ago. Here we show that this assumption is invalid for the only genus for which many taxa and multiple genetic markers have been analysed. Patterns of divergence exhibited by allozymes and the mitochondrial COI gene are highly concordant for 15 pairs of snapping shrimp in the genus Alpheus, indicating that they provide a reasonable basis for estimating time since cessation of gene flow. The extent of genetic divergence between pairs of sister species varied over fourfold. Sister species from mangrove environments showed the least divergence, as would be expected if these were among the last habitats to be divided. Using this pair yields a rate of sequence divergence of 1.4% per one million years, with implied times of separation for the 15 pairs of 3 to 18 million years ago. Many past studies may have overestimated rates of molecular evolution because they sampled pairs that were separated well before final closure of the Isthmus.

Differences in arrival times often exceed a month, and later arriving individuals are often in poorer condition. Habitat-specific isotopic signatures indicate that the quality of winter habitats occupied by American redstarts (Setophaga ruticilla) determines their physical condition and spring departure dates, which in turn result in variable arrival schedules and condition on temperate breeding grounds. These findings link events in tropical winter grounds with those in temperate breeding areas for a migratory songbird and provide evidence that winter habitats may be limiting.

SCUBA collected specimens were grown in the laboratory under identical culture conditions and their stable isotope signature was analyzed to characterize the influence of ontogeny and feeding rate on their delta (super 13) C and delta (super 18) O signals. The two types show a positive linear correlation between delta (super 13) C and delta (super 18) O with size. Type II is enriched in (super 13) C and (super 18) O relative to Type I and the enrichment per size increment is greater than for Type I. The carbon isotope composition of Type I tends towards lighter values at higher feeding rates whereas Type II is unaffected by the feeding regime. In order to determine if the isotopic response can be attributed to differences in growth characteristics and/or host/symbiont interactions, specimens were cultured under a variety of conditions and the pigment composition of freshly collected specimens was measured. Type I has a much lower photo-pigment content, which probably implies a lower gross photosynthetic rate. In addition, its growth and calcification rate are lower. The impact of these life processes on the stable isotope composition is discussed and it is argued that isotope fractionation is controlled by two linked processes. The carbon isotope fractionation is affected directly by a (super 12) C depletion or enrichment of the microenvironment via symbiont photosynthesis and host respiration, respectively. Concurrently, the life processes invoke a kinetic fractionation of the carbon and oxygen isotopes via their impact on the ambient carbonate chemistry.

However, terrestrial plants and vertebrates are preferentially preserved under very different taphonomic conditions, and diverse fossil floras and faunas are rarely found in close association. Big Multi Quarry and associated strata in the uppermost Fort Union Formation of the Washakie Basin, southwestern Wyoming, provide a uniquely detailed record of terrestrial fauna, flora, and climate during the early Clarkforkian. The Clarkforkian Land Mammal Age, approximately the last million years of the Paleocene, was an interval of global warming that had profound biotic consequences. The mammalian fauna of Big Multi Quarry, consisting of 41 species, is the most diverse known from a single Clark-forkian locality. Unlike most other Clarkforkian faunas, this assemblage is not significantly biased against small forms. Lipotyphlan insectivores were dominant, and arboreally adapted taxa were abundant and diverse. The closely associated and well-preserved fossil plant assemblage was overwhelmingly dominated by a single species belonging to the birch family. Floral richness, heterogeneity, and evenness were as low as in the Tiffanian of the same region, showing that forest structure remained monotonous even as climate warmed and mammals diversified in the Clarkforkian. The plant assemblage more closely resembles middle than early Clarkforkian floras of northern Wyoming, suggesting northward migration of the ranges of plant taxa coincident with warming. A great deal of research has focused on the unusually warm interiors of continents in the terminal Paleocene and early Eocene. Multiple lines of evidence from our study, including sedimentological indicators, analyses of the nearest living relatives and functional analogues of the fossil plants and animals, size and margin analysis of fossil leaves, and cenogram analysis of the mammalian fauna, indicate that southwestern Wyoming had a humid subtropical climate with little or no seasonal frost or marked dry season, well before the terminal Paleocene.

The Highborne Cay stromatolitic mats contain Schizothix as the dominant cyanobacterium and show millimeter-scale lamination: Some layers in the mat are soft (unlithified), whereas other layers are crusty (lithified). Lithified layers within the mats correspond to micritic horizons composed of thin (20-50 mu m) micritic crusts, which commonly overlie truncated, micritized carbonate sand grains. These features are identical to lithified laminae in the underlying stromatolite; the micritic crusts are similar in thickness to micritic laminae in many ancient stromatolites. Biogeochemical parameters in a representative stromatolitic mat from Highborne Cay were measured to identify the role of bacteria in precipitation and dissolution of CaCO (sub 3) . Depth distributions of O (sub 2) , HS (super -) , and pH were determined with microelectrode measurements in the field. Oxygen profiles were used to calculate photosynthesis and aerobic respiration. Sulfate reduction was determined using (super 35) SO (sub 4) (super 2-) and sulfide oxidation potential was measured in homogenized samples. Our results indicate that cyanobacterial photosynthesis, sulfate reduction, and anaerobic sulfide oxidation in stromatolitic mats at Highborne Cay are responsible for CaCO (sub 3) precipitation, whereas aerobic respiration and aerobic sulfide oxidation cause CaCO (sub 3) dissolution. A close coupling of photosynthesis and aerobic respiration in the uppermost few millimeters of the mats results in no, or very little, net lithification. Sulfur cycling, on the other hand, shows a close correlation with the formation of lithified micritic layers. Photosynthesis, combined with sulfate reduction and sulfide oxidation results in net lithification. Sulfate reduction rates are high in the uppermost lithified layer and, on a diel basis, consume 33-38% of the CO (sub 2) fixed by the cyanobacteria. In addition, this lithified layer contains a significant population of sulfide-oxidizing bacteria and shows a high sulfide oxidation potential. These findings argue that photosynthesis coupled to sulfate reduction and sulfide oxidation is more important than photosynthesis coupled to aerobic respiration in the formation of lithified micritic laminae in Highborne Cay stromatolites.

The fossil exhibits skeletal characters indicating that it is a juvenile member of a large clade of anoles that includes many extant Hispaniolan species and is characterized by close association between the clavicles and the lateral processes of the interclavicle. Standard external characters that can be scored in the fossil are identical to those of two of the four extant species in the A. chlorocyanus species group; however, because relatively few characters can be scored in the fossil, and because the polarities of the relevant characters are currently unknown, the fossil can be only tentatively referred to that group. The skeletal and external characters of the new fossil are also nearly identical to those of A. dominicanus, another Dominican amber anole; however, the latter fossil is relatively poorly preserved, and its currently known characters are identical to those of several extant species, including two species of the A. chlorocyanus species group. Body proportions and lamella counts of both amber fossils indicate that these lizards are trunk-crown anoles, that is, members of an ecologically and morphologically defined class of anoles specialized for life high on the trunks and in the crowns of trees. This finding is consistent with referral of the fossil anoles to the A. chlorocyanus species group, all extant members of which are trunk-crown anoles.

This study provides a detailed description of the species' breeding biology and provides evidence that this species might breed cooperatively. Although many parakeet pairs were observed roosting in solitary nests, breeding occurred only in nests within colonies or chambers within compound nests housing other parakeets. The male was responsible for all or most of the nest construction and maintenance. He fed the female during the incubation and early nestling periods, but later in the nestling period both the male and female fed the nestlings. Most breeding attempts involved a male-female pair, but three separate breeding attempts were made by trios (two trios included a female and two males, and the third trio was composed of a male and two females). In the trios, one of the auxiliary bird contributed less to the breeding effort than the primary male and female. The observations of trios support the idea that Monk Parakeets are similar to cooperative breeders, but the lack of cooperation in nest building indicates that colonial nesting may be a result of other benefits of group living, such as improved predator detection.

AN - 17136650; 4441480 AB - We investigated among-male variation in courtship waving in the fiddler crab Uca annulipes. Wave rate is positively correlated with both male carapace size and relative claw size (controlled for body size), and relative claw size is positively correlated with an index of body condition. An experimental reduction in the availability of food decreased male wave rate. These data suggest that some of the variation in wave rate among males is due to variation in male condition combined with energetic costs to waving (differential costs). However, we also found that the correlation between male size and wave rate decreased over the semilunar cycle. Later in the cycle, smaller males increase their wave rate relative to that of larger males. Previous work has shown that females are more likely to accept a smaller male as a mate later in the cycle. We suggest that smaller males invest disproportionately more in courtship later in the cycle because the potential benefits are greater due to their increased attractiveness to females (differential benefits). Alternative explanations for the observed temporal trend are also discussed.

AN - 69120190; 9876019 AB - Protein tyrosine phosphorylation is associated with sperm capacitation and the acrosome reaction in several mammalian species. Changes in phosphorylation of a 95-kDa protein in human, mouse, and domestic cat spermatozoa are known to be influenced by capacitation and exposure to zona pellucida (ZP) proteins. We previously reported diminished phosphorylation of 95- and 160-kDa proteins in spermatozoa from teratospermic cats, compared with normospermic domestic cats. To determine if these proteins and mechanisms are present in other species in the phenotypically diverse Felidae family, we examined the relationship between tyrosine-phosphorylated sperm proteins and sperm morphology in the leopard cat (approximately 65% normal sperm/ejaculate), tiger (approximately 65%), clouded leopard (approximately 15%), and cheetah (approximately 30%). Furthermore, we investigated the involvement of cyclic adenosine monophosphate (cAMP) in the regulation of sperm protein tyrosine phosphorylation. Specifically, we assessed the following: 1) presence of tyrosine-phosphorylated proteins in sperm extracts; 2) changes in protein tyrosine phosphorylation after sperm capacitation and swim-up separation; 3) impact of tyrosine kinase inhibition on leopard cat sperm protein phosphorylation and ZP penetration; and 4) involvement of a cAMP-dependent pathway in the regulation of protein tyrosine phosphorylation. Immunoblotting analysis with anti-phosphotyrosine antibody (PY20) indicated that a 95-kDa protein was present in all four species. Additional phosphorylated proteins were detected in the leopard cat (145- and 175-kDa proteins), tiger (185-kDa protein), clouded leopard (160- and 190-kDa proteins), and cheetah (115- and 155-kDa proteins). Sperm capacitation in vitro increased phosphorylation of one or more proteins in the leopard cat, tiger and clouded leopard, but not in the cheetah. Although swim-up separation increased the proportion of morphologically normal spermatozoa in the clouded leopard and cheetah, no changes were observed in phosphorylation of the 95-kDa sperm protein. Thus, phosphorylation of the 95-kDa protein appeared to be related to the condition of teratospermia. Exposing leopard cat spermatozoa to the tyrosine kinase inhibitor, tyrphostin, reduced (P < 0.05) phosphorylation of the 95- and 145-kDa proteins, as well as ZP penetration, without affecting sperm motility. Similarly, when spermatozoa were incubated in the presence of cAMP analogs or active and inactive stereoisomers of cAMP, phosphorylation of sperm proteins was either stimulated or inhibited. Together, these data suggest that protein tyrosine kinase mechanisms appear conserved within the family Felidae and are regulated by a cAMP/protein kinase A pathway.

Analyses of 22 surficial samples collected throughout the lagoon include 81 Sr isotopic analyses of mollusks, foraminifera, ostracods, barnacles, bryozoans, serpulid worm tubes, pore water, and gypsum crystals. Two salinity groups are distinguished in each sample: a lower salinity group ( approximately 1 ppt) mixed with a higher salinity group ( approximately 3-10 ppt) that, respectively, are interpreted as the modern biocoenosis and an older relict fauna. The relict fauna denotes higher salinity conditions in the lagoon prior to closure of the Aswan High Dam (1964), and the modern fauna records freshening of the lagoon. Recent decreased salinity is a response to regulated Nile River flow and increased discharge into Manzala of fresh water via canals and drains. Quantification of this short-term salinity change holds promise for study of modern lagoons in other world settings, and may provide paleoclimatic information for older lagoon sequences in the Nile River delta and the geologic record.

Topographic data for 10 mercurian lobate scarps, derived from Mariner 10 images using photoclinometry and digital stereoanalysis, indicate a range in maximum relief of 0.1 to 1.5 km and a range in horizontal shortening of 0.3 to 3.2 km, assuming fault-plane dips (theta ) of 25 degrees . Previous estimates of cumulative compressional strain recorded in the lobate scarps suggest a decrease in Mercury's radius of 1 to 2 km. Our estimate of compressional strain based on these new topographic measurements is approximately 0.056% (theta = 25 degrees ). This suggests that Mercury's radius decreased by <1 km.

On the Moon, flows of the last (phase III) effusion within the Imbrium impact basin were examined using Apollo photography. The longest phase III flow can be followed for 250 km, terminating approximately 400 km from the probable source vent. This flow has a width of 10 to 25 km, thickness of 10 to 30 m, and a medial channel preserved in its proximal reach, and it was emplaced on a regional slope of approximately 0.3 degrees . In the Tharsis region of Mars, a well-defined set of lava flows extends north from the topographic saddle between Ascraeus and Pavonis Montes. Viking Orbiter images show one flow that can be traced for 480 km, with a width ranging from 5 to 50 km, thickness of 30 to 100 m and a prominent medial channel in its proximal reach, and was emplaced on a regional slope of approximately 0.5 degrees to approximately 0.1 degrees . The Strenia Fluctus area on Venus consists of an array of intermixed radar-bright and radar-dark lobate flows, one of which can be traced for 180 km, with a width of 5 to 20 km, and an unknown thickness (but inferred to be approximately 30 m), and was emplaced on the lowland plains where the regional slope is only approximately 0.03 degrees . When viewed at the full Magellan resolution, this flow contains several flow margins, indicating its compound nature. Effusion rates were calculated for the simple lunar and Martian flows using published empirical and theoretical relationships, resulting in a broad range of 500 to 10 (super 8) (Moon) and 600 to 2 X 10 (super 8) (Mars) m (super 3) /s, with most likely values of approximately 5 X 10 (super 4) to approximately 10 (super 5) for both flows. The compound Venus flow would have required 494 years for emplacement at the typical Kilauea rate of approximately 5 m (super 3) /s, but the thermal balance of planetary tube systems could also be consistent with a rate at least an order of magnitude larger. The distinction between simple and compound flows is important to any evaluation of flow emplacement based solely on remote sensing data. Copyright 1998 by the American Geophysical Union.

We studied the patterns and mechanisms of immigration by postlarvae of 9 crab taxa in the small, high-salinity North Inlet estuary (South Carolina, USA) by sampling the plankton daily for 32 d over the length of the estuary. A concurrent study of larval production and flux showed that all taxa rapidly emigrate, thereby establishing empirically the importance of immigration in this estuary and giving us the rare opportunity to compare the relative species abundance of emigrating larvae and immigrating postlarvae. Contrary to the popular view that planktonic development in the sea uncouples larval recruitment from production, the community composition of emigrants and immigrants were comparable. Postlarvae immigrated at night and primarily on large amplitude flood tides. We show that this pattern is common in other estuaries and we argue that it reduces fish predation on immigrating postlarvae. Saltatory, up-estuary immigration was evident in 5 species that moved from the lower to the upper estuary (4 km) in 1 to 3 d. Although immigration rates have not been measured directly in other estuaries, a study of postlarval settlement in Mobile Bay suggests that rates may vary geographically in relation to variation in the tidal regime.

We model the buffer as a grid of cells, and each cell transmits a fixed fraction of the materials it receives. We consider the effects of variation in buffer width and buffer continuity, quantify the relative contributions of source elimination and buffer retention to total discharge reduction, and develop statistical relationships to simplify and generalize the models. Width variability reduces total buffer retention, increases the width needed to meet a management goal, and changes the importance of buffer retention relative to source elimination. Variable-width buffers are less efficient than uniform-width buffers because transport through areas of below-average buffer width (particularly gaps) dominates landscape discharge, especially for narrow buffers of highly retentive cells. Uniform-width models overestimate retention, so width variability should be considered when testing for buffer effects or designing buffers for water quality management. Adding riparian buffer to a landscape can decrease material discharge by increasing buffer retention and by eliminating source areas. Source elimination is more important in unretentive or wide buffers, while buffer retention dominates in narrow, retentive buffers. We summarize model results with simpler statistical relationships. For unretentive buffers, average width is the best predictor of landscape discharge, while the frequency of gaps was best for narrow, retentive buffers. Together, both predictors explain >90% of the variance in average landscape transmission for any value of buffer retentiveness. We relate our results to ecological theory, landscape-scale buffer effects, buffer management, and water quality models. We recommend more empirical studies of buffer width variability and its effects on material discharge. Landscape models should represent width variability and the nonlinear interactions between buffers and source areas.

There it eventually became the vector of avian malaria, Plasmodium relictum, a disease that severely limits the size and distribution of endemic forest bird populations in Hawaii. Cx.p. quinquefasciatus has a circumtropical distribution and is also the vector for human diseases such as lymphatic filariasis and several encephalitis. We are studying the evolution of virulence in host-parasite systems by examining the recently formed avian malaria-mosquito-bird association in Hawaii. We are examining the population structure of Cx.p. quinquefasciatus and their association with malaria parasites using microsatellites as one of the genetic markers. Because of their high mutation rates, microsatellites are ideal markers to measure the divergence of such recently separated populations. Here we describe the isolation, and characterization, of eight polymorphic microsatellite loci in Cx.p. quinquefasciatus.

Throughout the US dams are being considered for decommissioning. This controversial idea is gaining momentum as the nation faces the problems of an aging dam infrastructure. Many of the nation's dams are over fifty years old and require repair; many are also rated high hazard for failure. In considering their potential removal, dams are evaluated for their age, history, contribution to power generation, impact on the environment, and use in flood control. Some of the dams which are under consideration include the Elwha Dam (Washington), Glen Canyon Dam (Arizona), Ocklawaha River (Florida), and Edwards Dam (Maine).

The Sargasso reaches from the West Indies to the Azores. Sailing vessels are powered by currents driven by westerlies and the northeasterly trade winds. Eddies within the sea help circulate nutrients, fish, and plankton in this otherwise still sea. The net-like spread of sargassum has been the bane of sailors for centuries, who also sought to avoid the light and fickle winds of the Sargasso.

The strategically important Strait is the source of ongoing conflict between Turkey, Russia, and the Ukraine, over access to burgeoning oil fields and control over the passage. The high level of traffic crossing through the narrow and barely navigable strait raises the inevitability of accidents and risk to both humans and the environment. Control of the Strait has been addressed in international treaties since 1833.

Of the 1346 foliar items analyzed, 31.8% were attacked by insect folivores. This Permian insect herbivory approximated one-third the level in modern tropical to temperate forests. Three taxa of Gigantopteridaceae exhibited disproportionately high insect consumption levels, ranging from 3.1 to 4.4% of leaf area, and attack frequencies of 39.6 to 82.8% -- levels comparable to taxon-specific values for modern woody dicotyledonous angiosperms. Qualitative analysis of folivory type also indicates that five of the eight categories of herbivore damage occurring on this flora were confined to or overwhelmingly represented on Gigantopteridaceae, suggesting preferential host specificity for Gigantopteridaceae by insect folivores. By contrast, other pteridophylls, conifers, cycadophytes, and two taxa of uncertain affinity, showed low levels of leaf area removal and attack frequencies. The Gigantopteridaceae, an enigmatic group of Permian plants with large, megaphyllous foliage, foreshadowed physiognomic attributes occurring in later angiosperms. Both groups had similar consumption patterns and intensities by insect folivores. In this moderately diverse Early Permian flora, insect folivory was significant, at least in one riparian environment outside the Euramerican coal-swamp ecosystem, indicating that modern modes and magnitudes of insect consumption of vascular plant tissue were in place during the Late Paleozoic.

The voluminous GRs (constituting >80 vol% of CRBs) are totally aphyric basaltic andesites. GRs show very narrow and coherent chemical trends both in major and trace elements as well as isotopes. The silica-rich GRs (SiO (sub 2) = 52-56 wt%) can be produced by direct partial melting of a MORB like source material (CRB72-31) at approximately 2 GPa or approximately 70 km depth. By 30-50% partial melting of the CRB72-31, the entire compositional range of the GRs can be produced in a narrow temperature interval (1300-1350 degrees C) at approximately 2 GPa. The aluminous clinopyroxene that appears in the above melting range is consistent as the major controlling phase of the GR trends. The partial melts are very similar to the GRs except for Al (sub 2) O (sub 3) and FeO which could be due to the mismatch in the source rock composition. Judging from the variation in REE, involvement of garnet in GR magma genesis can be ruled out. Small amounts of plagioclase (10-30 wt%) may be present in the partial melting residue. Judging from REE patterns and Nd isotopes of the GRs, the source rock should be unfractionated in REE. Based on the melting experiments, a heterogeneous plume model is proposed for the initial stage of the Yellowstone hot spot. Large lithologically distinct blobs of old oceanic crust components were included in the plume head. The GR magmas were produced by partial melting of the oceanic crust components at the bottom of the North American lithosphere. Similar melting processes of basalt/peridotite composite source may be operating in other LIPs (large igneous provinces). The GR type genuine oceanic crust derived melts may be seen where the ambient peridotite remains under subsolidus conditions. Volume and temperature of mantle plumes may have been overestimated, because contributions from the recycled oceanic crust is so large and the current mantle melting models concern only peridotite source.

Here we offer a theoretical and empirical test of this assertion using data from a 50-ha census plot in Panama. Theory indicates that higher rates of population change, lambda , lead to more steeply declining size distributions (more juveniles relative to adults). But other parameters also affect the size distribution: lower growth rate of juveniles and lower survival at any size produce more steeply declining size distributions as well. Empirical evaluation of 216 tree populations showed that juvenile growth was the strongest predictor of size distribution, in the direction predicted by theory. Size distribution did correlate with population growth, but weakly and only in understory species, not canopy species. Size distribution did not correlate with the growth rate of larger individuals nor with survival. Results suggest that static information on the size distribution is not a good predictor of future population trends, while demographic information is. Fast-growing species will have fewer juveniles in the understory than slow-growing species, even when population growth is equal.

EPFs were rare in blue-headed vireos (1/37 nestlings), but common in red-eyed vireos (11/19 nestlings). We studied the behavior of blue-headed vireos to determine what factors could promote genetic monogamy. We found no evidence that males mate guarded to prevent extrapair copulations from occurring. Males did not follow fertile mates closely when mates left the nest (14-25% of female departures) and, during the egg-laying period, males were often alone on the nest (22.3 min/h). Female blue-headed vireos, but not red-eyed vireos, obtain direct benefits from social mates such as nest building and incubation (49.1% of the total), and they assess male quality long before becoming fertile. Female blue-headed vireos spent more time incubating when their mates had low incubation effort. Furthermore, male incubation effort was positively correlated with nest survival during incubation. We discuss the evolution of genetic monogamy and sex role convergence in blue-headed vireos in relation to asynchronous breeding.

I. Juvenile survival without parents AN - 17104397; 4415410 AB - Extended parental care is found among a variety of marine peracarid species including endobenthic and epibenthic amphipods. After hatching from the female's brood pouch, small juveniles enjoy parental care for time periods of several days up to several weeks. This study examined whether small juvenile amphipods can survive without parental care to determine if this reproductive strategy is obligate or facultative. Juveniles of the burrow-dwelling species Leptocheirus pinguis (Stimpson 1853) and Casco bigelowi (Blake 1929) survived well in predator-free trays, indicating that extended parental care in these species is a facultative reproductive strategy - juveniles can survive without their parents. Medium-sized juveniles of the epibenthic, suspension-feeding species Dyopedos monacanthus (Metzger 1875) survived relatively well in predator-free traps, but small juvenile D. monacanthus did not. This low survival rate of small D. monacanthus, even in predator-free trays, demonstrates that extended parental care is obligate for the survival of early juvenile stages in this epibenthic amphipod. When exposed to predators, juveniles of all three amphipod species were susceptible to predation, and reacted by emigration. Most juvenile L. pinguis and C. bigelowi emigrated or disappeared from sand shrimp Crangon septemspinosa treatments, but many remained in hermit crab Pagurus longicarpus treatments. Almost all juvenile D. monacanthus emigrated from both sand shrimp and hermit crab treatments, indicating that this epibenthic amphipod species is very susceptible to epibenthic predation. Survival of juvenile D. monacanthus was lower than that of L. pinguis and C. bigelowi both in predator-free and in predator trays. These results suggest that juveniles of this and other epibenthic peracarids depend on maternal care to a higher degree than juveniles of endobenthic burrow-dwelling species.

The subsequent evolutionary history of this agricultural symbiosis was inferred from phylogenetic and population-genetic patterns of 553 cultivars isolated from gardens of "primitive" fungus-growing ants. These patterns indicate that fungus-growing ants succeeded at domesticating multiple cultivars, that the ants are capable of switching to novel cultivars, that single ant species farm a diversity of cultivars, and that cultivars are shared occasionally between distantly related ant species, probably by lateral transfer between ant colonies.

Located in the area of the Fennoscandian land uplift, SWEPOS is the main measuring device for the BIFROST project, aiming primarily at determination of crustal motions and changes in global sea level in conjunction with postglacial rebound. As a future prospect the project will contribute to determine present-day changes in the oceanic water budget as well as strive for a more complete understanding of the viscoelastic structure of crust and mantle. We show solutions of site positions obtained from the daily processing of the GPS observations. We determine their variations in time, discerning them from plate or frame orientation, and discuss a number of perturbation effects. Among these the possibility of random walk monument motion is considered. The feasibility of single-site solutions rather than baseline pairs is demonstrated. On the basis of 800 days of operation of the permanent network, data analysis is able to confirm the general rebound pattern. Comparison with both modelling results and evidence from mareograph and precise levelling shows high rates of vertical surface displacement from GPS measurements in the centre of the Pleistocene glaciation region. We discuss the possibility of rate biases due to problems with the terrestrial reference frames.

WEGENER currently has three scientific objectives which are related to plate-boundary processes, sea-level and height changes, and postglacial rebound. In a full exploitation of the space-geodetic techniques, namely SLR, VLBI and GPS, the individual scientific projects do not only pursue these objectives but also contribute to improving and developing the observation techniques as well as the modelling theories. In the past, particularly SLR observations within WEGENER-MEDLAS have provided a fundamental contribution to determine the regional kinematics of the tectonic plates in the Mediterranean with high precision. With GPS, spatially denser site distributions are feasible, and in several WEGENER projects detailed studies of tectonically active areas were possible on the basis of repeated episodic GPS observations. Current projects associated with WEGENER are successful in separating crustal movements and absolute sea-level variations as well as in monitoring postglacial rebound. These tasks require high-precision height determinations, a problem central to all of the present WEGENER activities. In these projects, continuously occupied GPS sites are of increasing importance. Time series of heights observed with continuous GPS can be determined with a few centimeters RMS error thus enabling the reliable estimates of vertical rates over relatively short time intervals. Regional networks of continuous GPS sites are already providing results relevant, for example, for the study of postglacial rebound. The Mediterranean area is an extraordinary natural laboratory for the study of seismotectonic processes, and the wealth of observations acquired in previous WEGENER projects together with new space-geodetic observations will allow the test of geophysical hypotheses linking three-dimensional deformations of the Earth's surface to the dynamics of the Earth's interior. In particular, it is anticipated that WEGENER projects will aim at a test of the slab-detachment hypothesis. The complex investigations on sea-level fluctuations presently carried out at basin scale from the Strait of Gibraltar to the Black Sea make it possible to study the present and recent past interactions of ocean, atmosphere and solid Earth, as well as to develop appropriate models to assess future aspects.

The model assumes that as condensation proceeds, a specified fraction (called the isolation degree, xi ) of the existing condensate is steadily withdrawn from reactive contact with the residual gas, presumably as a result of the growth and aggregation of condensed mineral grains. The isolated condensates may remain in the condensing system as coarse inert objects; whereas, the mineral grains that are still in reactive contact with residual nebular gases are in the form of fine dust. This paper describes the condensation with partial isolation (CWPI) model of condensation and uses it to study condensation in a nebula of solar composition at a total pressure of 10 (super -5) bar. The systematic isolation of condensates from residual nebular gases has profound effects on the condensation sequence. At xi values >0.2%, the condensation sequence is essentially independent of the isolation degree and identical to the classic condensation sequence. At xi values >2.5%, the condensation sequence is also independent of the isolation degree and closely resembles the "inhomogeneous accretion model" or "chemical disequilibrium model" of condensation. In the intermediate range of xi values, the character of the condensation sequence is very sensitive to the degree of chemical fractionation caused by condensate isolation. The mineralogy of chondritic meteorites is not consistent with condensation sequences having xi >2.5; this is an upper limit on the xi values that is characteristic of condensation in the solar nebula. The mineralogy and chemistry of carbonaceous and enstatite chondrites can be explained by accretion of isolated condensates formed at xi values of < or =0.1% and 0.7-1.5%, respectively, providing that segregation of the inert coarse objects and fine reactive dust occurred in the nebula. Segregation of these two categories of condensate may have been responsible for the observed volatility-based chemical fractionations among chondritic meteorites.

They are both tetralophodont forms belonging to the tribe Phyllotini (Sigmodontinae) and are assigned to Ichthyurodon ameghinoi, gen. et sp. nov., and Olympicomys vossi, gen. et sp. nov. Phylogenetic analyses involving extant phyllotines, the two new species, and two other newly discovered extinct phyllotines result in a refined and expanded concept of the clade consisting of Loxodontomys and the Reithrodon generic group. The generic diversity of this clade is thus doubled from four to eight. Several of the fossil genera appear to represent transitional forms, although Ichthyurodon, gen. nov., possesses dental traits unique among the members of the subfamily Sigmodontinae. The significance of the new species and their faunal context for our understanding of the paleoecology of the southern cone of South America is discussed.

Scanning electron microscopy shows that original skeletal rods and needles recrystallize on the sea floor to a variety of equant micritic fabrics. In thin section, this textural alteration corresponds to progressive micritization, with loss of the familiar golden brown color exhibited by fresh miliolids and Halimeda and gradual development of gray cryptocrystalline carbonate. X-ray diffraction and electron microprobe studies show that this textural alteration may be accompanied by mineralogical changes from Mg-calcite to aragonite or from aragonite to Mg-calcite. Our findings support petrographic studies that reported syndepositional recrystallization in a wide variety of carbonate grains about thirty years ago, but which have been largely ignored. Together, these studies indicate that carbonate recrystallization is a widespread process of early diagenesis. Extensive recrystallization in shallow tropical seas challenges basic principles regarding the setting and timing of textural and mineralogic alteration of metastable carbonate grains. In addition, recognition of recrystallization as an important process of micritization contradicts prevailing theories that micritization results solely by infilling of microborings. Finally, our findings raise fundamental questions concerning the nature of carbonate crystal structure, mechanisms of crystal growth, and driving forces for recrystallization. Answering these questions will require sedimentologists to step beyond traditional bounds into fields such as biomineralization and materials science.

The view through the window of a microcosm AN - 17244379; 4535234 AB - Our results have provided an estimate of the biodiversity of pan tropic coral reefs that is more than 3 times higher than that previously published. The biodiversity of global coral reefs has recently been estimated at approximately 1 million species based on what is currently known about tropical rain forests. However, in order to determine the actual biodiversity of even a single coral reef locality, an extensive team effort on the part of hundreds of specialists would be required. Close examination of the mature 5 m super(2) Caribbean coral reef microcosm described in this paper provided 534 species, with an estimated 70% tallied. Using the area/diversity relationship S=kA super(Z), we were able to more accurately assess the probable biodiversity of wild reefs. This outstanding species biodiversity, based in an extensive range of higher taxa, reconfirms the essential need to restore and conserve one of the most precious ecosystems on earth.

We radio-tagged Wood Thrushes (Hylocichla mustelina), and monitored their movements and behavior on the U.S. Marine Corps Base, Quantico, Virginia (38 degree 40' N, 77 degree 30' W) from May-Oct. of 1993-1995. The molt period in adults extended from late July to early October. Molt of flight feathers lasted an average of 38 days (n = 17 birds) and there was no significant difference in duration between sexes. In 21 observed and captured individuals, all the rectrices were lost simultaneously or nearly so, and some individuals dropped several primaries over a few days. Extensive molt in Wood Thrushes apparently impaired flight efficiency, and birds at this stage were remarkably cautious and difficult to capture and observe. All breeding individuals were observed molting 1-4 days after fledgling independence or last-clutch predation, except for one pair that began molt while still caring for fledglings. Our data indicate that energetics or flight efficiency constraints may dictate a separation of molt and migration. We did not observe Wood Thrushes leaving the Marine Base before completion of flight-feather molt. Departure of individuals with molt in body and head, however, was common. We caution against interpreting the lack of observations or captures of molting individuals on breeding sites as evidence that birds actually have left the area. We argue also that current reports on overlapping of molt and migration based on observations of molting individuals out of the breeding range could be misleading because some individuals may leave the breeding area to molt in other places before starting a true migration.

Paleontologists are currently documenting biotic recoveries from six major mass extinctions and several smaller biotic crises. Although the immediate responses are remarkably similar after each event, with low-diversity assemblages dominated by widespread, eurytopic species, the recovery response in the long-term is more varied. Lineages that survive the extinction can lack the resilience for recovery, whereas others vanish from the fossil record seemingly to return from the dead after several million years.

Fewer than 1500 elephants remain free roaming in Thailand, and 3800 captive elephants do not always fare well, despite their long history of service to the Thai economy. The Thai Elephant Conservation Center, owned by a government-run timber enterprise, includes a hospital where victims of overwork and abuse are treated. This abuse is a recent aberration in a long history of mutual respect between elephants and their handlers. Domesticated elephants have been released into the wilderness and closely tracked to examine the prospects for captive breeding programs. The greatest risk to these elephants is capture by illegal loggers who put them to work to clear the dwindling forests of the nation.

Atmospheric deposition further contributes as a source of N. These nonpoint inputs of nutrients are difficult to measure and regulate because they derive from activities dispersed over wide areas of land and are variable in time due to effects of weather. In aquatic ecosystems, these nutrients cause diverse problems such as toxic algal blooms, loss of oxygen, fish kills, loss of biodiversity (including species important for commerce and recreation), loss of aquatic plant beds and coral reefs, and other problems. Nutrient enrichment seriously degrades aquatic ecosystems and impairs the use of water for drinking, industry, agriculture, recreation, and other purposes. Based on our review of the scientific literature, we are certain that (1) eutrophication is a widespread problem in rivers, lakes, estuaries, and coastal oceans, caused by over-enrichment with P and N; (2) nonpoint pollution, a major source of P and N to surface waters of the United States, results primarily from agriculture and urban activity, including industry; (3) inputs of P and N to agriculture in the form of fertilizers exceed outputs in produce in the United States and many other nations; (4) nutrient flows to aquatic ecosystems are directly related to animal stocking densities, and under high livestock densities, manure production exceeds the needs of crops to which the manure is applied; (5) excess fertilization and manure production cause a P surplus to accumulate in soil, some of which is transported to aquatic ecosystems; and (6) excess fertilization and manure production on agricultural lands create surplus N, which is mobile in many soils and often leaches to downstream aquatic ecosystems, and which can also volatilize to the atmosphere, redepositing elsewhere and eventually reaching aquatic ecosystems. If current practices continue, nonpoint pollution of surface waters is virtually certain to increase in the future. Such an outcome is not inevitable, however, because a number of technologies, land use practices, and conservation measures are capable of decreasing the flow of nonpoint P and N into surface waters. From our review of the available scientific information, we are confident that: (1) nonpoint pollution of surface waters with P and N could be reduced by reducing surplus nutrient flows in agricultural systems and processes, reducing agricultural and urban runoff by diverse methods, and reducing N emissions from fossil fuel burning; and (2) eutrophication can be reversed by decreasing input rates of P and N to aquatic ecosystems, but rates of recovery are highly variable among water bodies. Often, the eutrophic state is persistent, and recovery is slow.

The new combination Syzygioides americana (Lesquereux) Manchester, Dilcher et Wing, comb. nov. applies to leaves that formerly were attributed to Eucalyptus and Eugenia. The opposite, decussately arranged leaves are similar in architecture to those of extant Syzygium fluviatilis (Hemsley) Merrill et Perry and S. jambos (L.) Alston, but the attached leathery fruits, with incurved persistent calyx and short capitate stigmas, are unlike those of extant Eucalyptus, Syzygium, Eugenia and other extant genera. Syzygioides americana first appears in the Lower Eocene of the Rocky Mountain region and is common in the Middle Eocene. The improved understanding of this fossil shows the presence of an extinct myrtaceous genus in the Eocene and demonstrates the need for caution in attempting to identify isolated fossil leaves to extant genera of the Myrtaceae.

We present data on the occurrence of fostering at Laysan Island, NWHI, and compare spatial patterns and behavior of seals at Laysan Island and East Island, French Frigate Shoals, to investigate the importance of density in frequency of fostering. Fostering was common at Laysan Island; 53% of 17 females nursed pups other than their own for some part of their lactation period. This level of fostering was significantly less than that at East Island, where ca. 90% of females fostered pups in 2 separate years (n = 30 in 1987 and 10 in 1989). Density of females was significantly lower at Laysan Island than East Island (0.5 versus 1.5 females/1,000 m super(2)), and nearest female neighbors were significantly farther away (58 versus 27 m) at Laysan Island. Stage of lactation at which fostering started, the total duration of foster care and the duration of fostering episodes did not differ between colonies. However, mean number of pups fostered per female at the denser colony (2.3 pups, East Island) was greater than at the less dense colony (1.3 pups, Laysan Island). No difference occurred between islands in relative frequency of aggressive interactions between females, which are known to result in females exchanging pups. High female density does appear to increase fostering frequency but not through female-female aggression as expected. Instead, high density increases the likelihood that separated females and pups will encounter another potential partner before reuniting.

We hypothesized that species with long-lived leaves should be more tolerant of an increase in light levels than species with short-lived leaves. In understorey plants of 12 shade-tolerant rain-forest species, photoinhibition, measured as a reduction in the chlorophyll fluorescence parameter F sub(v)/F sub(m) when leaf discs were exposed to 1 h at 1000 mu mol m super(- 2)s super(-1), was greater in species with short-lived leaves than species with long-lived leaves. Less photoinhibition in species with long-lived leaves was not associated with higher levels of non-photochemical dissipation (NPQ) of absorbed light, but may be the result of a higher yield of photosystem II compared with short-lived leaves. Thus, species with long-lived leaves are more tolerant of abrupt increases in light that occur when tree-fall gaps are formed than species with short-lived leaves. Discs from leaves of all species growing in tree-fall gaps had higher levels of NPQ, yield of photosystem II and more rapid recovery from photoinhibition than leaves developed in the understorey; however, there were no differences among species with short- and long-lived leaves.

Avian predation is common, especially of crabs unable to escape into burrows. Mating pairs form in two ways. Females either mate on the surface at their burrow entrance ('surface mating') or leave their own burrow and sequentially enter and leave ('sample') courting males' burrows, before staying in one to mate underground ('burrow mating'). We tested whether perceived predation risk affects the relative frequency of these mating modes. We first observed mating under natural levels of predation during one biweekly, semi-lunar cycle. We then experimentally increased the perceived predation risk by attracting grackles (Quiscalus mexicanus) to each half of the study site in two successive biweekly cycles. In each experimental cycle, crabs were significantly less likely to mate on the side with more birds. Moreover, on the side with elevated predation risk, the number of females leaving burrows to sample was greatly reduced relative to the number of females that surface-mated. Males waved less and built fewer mud pillars, which attract females, when birds were present. We discuss several plausible proximate explanations for these results and the effect of changes in predation regime on sexual selection.

High levels of genetic variation were revealed in samples of adults, saplings, and seedlings. The more-variable loci exhibited less stability in allelic composition across sites and stages. The number of alleles per hectare (ha) of forest was similar when continuous forest plots were compared to plots from fragmented forest for all three stages. This pattern also held for the number of unique multilocus adult and sapling genotypes, but the number of unique seedling genotypes per ha of fragmented forest greatly exceeded expectations based on continuous forest data, probably due to the concentration of seeds into remnant forest patches by foraging bats. Significant inbreeding and genetic differentiation were most often associated with the fragmented forest and the seedlings. Finally, principal component analysis reaffirmed that a bottleneck, acting in concert with pre-existing genetic structure in the adults, had led to enhanced and rapid divergence in the seedlings following deforestation, a result that is of central interest for landscape management.

A 1 cm super(2) CdZnTe detector was placed adjacent to a thick BGO anticoincidence shield and flown piggybacked onto the EXITE2 scientific balloon payload. The planar shield was designed to veto background counts produced by local gamma-ray production in passive material and neutron interactions in the detector. The CdZnTe and BGO were partially surrounded by a Pb-Sn-Cu shield to approximate the grammage of an X-ray collimator, although the field of view was still approximately 2 pi sr. At an altitude of 127000 feet we find a reduction in background by a factor of 6 at 100 keV. The non-vetoed background is 9x10 super(-4) cts cm super(-2) s super(-1) keV super(-1) at 100 keV, about a factor of 2 higher than that of the collimated (4.5 degree FWHM) EXITE2 phoswich detector. We compare our recorded spectrum with that expected from simulations using GEANT and find agreement within a factor of 2 between 30 and 300 keV. We also compare our results with those of previous experiments using passive lead and active NaI shields, and discuss possible active shielding schemes in future astronomy missions employing large arrays of CdZnTe detectors.

Hypervariable genetic markers were used to reconstruct a population-level pedigree in fragmented tropical forest for the tree Symphonia globulifera. Though seedlings occurred only in remnant forest, the pedigree showed that most seedlings had been produced by sequentially fewer adults in pasture, creating a genetic bottleneck. The pedigree also implicated shifts in the foraging of animals that disperse pollen and seed in a secondary constriction of the bottleneck. These results suggest that tropical conservation strategies should anticipate complex, cryptic responses to fragmentation. JF - Science (Washington) AU - Aldrich, PR AU - Hamrick, J L AD - Dep.

These factors, with the abundance and distribution of metal and troilite, are used to classify winonaites which are described in detail with many photomicrographs, modes, mineralogy (low-Ca pyroxene, olivine, Ca pyroxene, Fe, Fe-Ni-metal, with minor chromite, daubreelite, alabandite, schreibersite, graphite, K-feldspar and apatite), bulk major and trace element compositions, olivine and pyroxene analyses, and trapped and cosmogenic noble gases and their isotopes. The results show that winonaites are primitive achondrites that suffered limited partial melting, with brecciation and metamorphism of the precursor body. The precursor was probably chondritic unlike any known chondrite group. (super 39) Ar/ (super 40) Ar age determinations of samples of Pontlyfni, Winona and Mt Morris range 4400-4540 m.y.; cosmic ray exposure ages are approximately 20-80 m.y. Brecciation and metamorphism of the precursor body occurred early in the solar system.

Of these potential climatic shifts, it is precipitation that will have the most impact on tropical forests, and seasonal patterns of rainfall and drought will probably be more important than the total quantity of precipitation. Many tree species are limited in distribution by their inability to survive drought. In a 50 ha forest plot at Barro Colorado Island in Panama (BCI), nearly all tree and shrub species associated with moist microhabitats are declining in abundance due to a decline in rainfall and lengthening dry seasons. This information forms the basis for a simple, general prediction: drying trends can rapidly remove drought-sensitive species from a forest. If the drying trend continues at BCI, the invasion of drought-tolerant species would be anticipated, but computer models predict that it could take 500 or more years for tree species to invade and become established. Predicting climate-induced changes in tropical forest also requires geographic information on tree distribution relative to precipitation patterns. In central Panama, species with the most restricted ranges are those from areas with a short dry season (10-14 weeks): 26-39% of the tree species in these wet regions do not occur where it is drier. In comparison, just 11-19% of species from the drier side of Panama (18 week dry season) are restricted to the dry region. From this information, I predict that a four-week extension of the dry season could eliminate 25% of the species locally; a nine-week extension in very wet regions could cause 40% extinction. Since drier forests are more deciduous than wetter forests, satellite images that monitor deciduousness might provide a way to assess long-term forest changes caused by changes in drought patterns. I predict that increasing rainfall and shorter dry seasons would not cause major extinction in tropical forest, but that drying trends are a much greater concern. Longer dry seasons may cause considerable local extinction of tree species and rapid forest change, and they will also tend to exacerbate direct human damage, which tends to favor drought-adapted and invasive tree species in favor of moisture-demanding ones.

The tidal marsh populations are consistently grayer with more extensive black markings (particularly in the crown), and their bills are larger. These differences are variously shared with other species of salt marsh birds and small mammals. We analyzed mitochondrial DNA sequences (5' end of control region, COII/t-lys/ATPase8, and ND2) of Swamp Sparrows and found low levels of genetic variation and no evidence of geographic structure. These results suggest a rapid and recent geographic expansion of Swamp Sparrows from restricted Pleistocene populations. Morphological differentiation has occurred without long-term genetic isolation, suggesting that selection on the divergent traits is intense. The grayer and more melanistic plumage is probably cryptic coloration for foraging on tidal mud, which tends to be grayish as a result of the formation of iron sulfides, rather than iron oxides, under anaerobic conditions.

We used large (3-6 m super(2)) flow-through chambers to sample N sub(2)O emissions from surface soils. N sub(2) emissions were estimated by comparing N sub(2)O efflux in chambers with or without acetylene addition. Water and solutions of nitrate or sucrose were sprinkled on the soil within the chambers and subsequent changes in N sub(2)O efflux were observed continuously for several days. In 23 of 25 cases the soil beneath the chambers released N sub(2)O at 0.19-17 mu g N sub(2)O-N m super(-2) h super(-1) prior to experimental treatments. In two chambers, there was consistent uptake of N sub(2)O from the atmosphere at 2.2 and 1.0 mu g N sub(2)O-N m super(-2) h super(-1) prior to treatments. Release of N sub(2)O was sometimes stimulated by adding water, usually stimulated by adding sucrose and always stimulated by adding nitrate. Stimulation by either nitrate and sucrose separately may reflect the heterogeneity of soil conditions that limit denitrification. After additions of nitrate or sucrose, N sub(2)O efflux rates usually peaked at more than 10 times pre-treatment rates, but effects of adding water were less pronounced. Responses to treatments began within minutes or hours and usually did not persist for more than a day. The rapid response suggests that denitrifiers possess a stock of enzymes ready to exploit rapidly changing conditions in the soil. Acetylene added to the air in the chambers penetrated at least 40 cm into the soil within 10 h, reaching concentrations of 3-8 ml l super(-1) in the soil gas. Adding acetylene alone had no consistent effect on N sub(2)O flux. However, adding acetylene and nitrate together resulted in greater stimulation of N sub(2)O efflux than adding nitrate alone, presumably because acetylene inhibits N sub(2)O reduction to N sub(2). The lack of effect of acetylene alone suggests that inhibition of N sub(2)O reduction may not be effective in situ unless nitrate is also added. Based on the combined effects of acetylene and nitrate, we infer that 8.2-90% of the N sub(2)O produced after adding nitrate without acetylene was converted to N sub(2). The amount of N sub(2)O-N released after adding nitrate and acetylene was only 0.19-5.5% of the nitrate-N added.

Ammodon Marsh, 1893 also is a junior subjective synonym of Daeodon. Five species have been named that we assign to Daeodon; D. shoshonensis Cope, 1879, D. leidyanus (Marsh, 1893), D. mento (Allen, 1926), D. hollandi (Peterson, 1905b), and D. minor (Loomis, 1932), and we tentatively consider all to represent a single species, D. shoshonensis Cope, 1879. The type material of D. leidyanus, from the basal Kirkwood Formation near Farmingdale, New Jersey is of early Miocene (late Arikareean) age. Other Daeodon occurrences range in age from late Oligocene (Arikareean) to early Miocene (Hemingfordian).

Scanning electron microscopy of gills and air-tube of H. fossilis showed fusion of secondary lamellae. Swelling, corrugation and dissociation of filamental epithelium were observed at long term exposure of 20 days. At 96 h of exposure the gill showed some recovery resembling to some extent to the control gill. Bimodal oxygen uptake of control and treated fishes confirmed the extent of damages caused by malathion on gills. The total oxygen uptake increased from 4.10% to 11.80% in 24 h to 72 h but during 96 h of exposure the fish showed somewhat normal trend.

These two zones have very different histories and dynamics of interaction between the two taxa. Orchelimum nigripes and O. pulchellum (Tettigoniidae: Conocephalinae) are distributed west and east, respectively, of the Appalachian Mountains, from the Great Lakes to the Gulf Coast and along the Atlantic Coastal Plain from New York to the Florida Keys, but are not found in the Appalachians themselves. In addition, during this century O. nigripes has become established in a small area east of the Appalachians, in the Potomac River basin, where it has completely replaced O. pulchellum along the river corridor above Washington, DC. I sampled katydids from 40 sites across both hybrid zones and mapped geographic patterns of genetic variation (allele frequencies at two diagnostic loci) and variation in a morphometric index for males. Although the two taxa are quite distinct over most of their extensive distributions, there is clear evidence of introgression in both contact zones. In the Deep South, samples from a transect along the Gulf Coast define a broad hybrid zone of about 50-100 km, while samples from a transect 200 km to the north define a zone of about 150-250 km in width. Only one Deep South population shows a deviation from Hardy-Weinberg equilibrium at either locus, and there is no evidence of linkage disequilibrium in any Deep South population. In the Potomac region, there is a narrow upstream-downstream hybrid zone along the river. Within the Potomac River floodplains downriver from Washington, DC, as well as outside the floodplains throughout the region, O. pulchellum is present in abundance, but O. nigripes markers are virtually absent. Within the floodplains upriver from Washington, DC, O. nigripes is abundant, but O. pulchellum markers are virtually absent. All four mixed ancestry Potomac populations sampled show strong and highly significant linkage disequilibrium, although only one clearly deviates from single-locus Hardy-Weinberg equilibrium. The position of the Deep South hybrid zone is generally consistent with interspecific and intraspecific phylogeographic patterns previously reported for numerous taxa from the southeastern United States. The observed genetic and morphometric clines appear to be the result of neutral introgression over thousands of years. In the much younger Potomac hybrid zone, O. nigripes appears to be spreading downriver, interbreeding with O. pulchellum, and replacing it. The mechanism for this replacement remains uncertain, but may be clarified by ongoing behavioral, genetic, and breeding studies.

This study shows that seedlings of Tipularia discolor (cranefly orchid) primarily occur on decomposing wood. Extensive searches of decomposing logs and stumps in mature and successional forests revealed seedlings at 24 sites, of which 15 could be identified as originating from seven different deciduous trees and one conifer. Seeds were planted in natural habitats to test the hypothesis that germination requires decomposing wood. In one experiment, seeds were placed into soil at sites where adult plants were abundant; no germination resulted. In a second experiment, germination of seeds sown in ambient soil was compared with sowings in plots amended with decomposing wood collected from a stump where spontaneous seedlings grew. Germination was much more frequent in plots amended with decomposing wood. We conclude that germination of T. discolor is stimulated in substrates that contain decomposing wood; judging from the occurrence of spontaneous seedlings, wood from at variety of tree species offer a suitable substrate.

Prior to mid-century, scientists generally assumed that the primary source of energy for coral reefs was derived from the plankton brought by ocean currents and trade wind seas. However, the largely algal photosynthetic component of coral reefs, which greatly exceeds the animal component in biomass, is mostly diminutive, often symbiotic within animal tissues, and easily overlooked. Odum and Odum (1955) demonstrated for an Eniwetok reef fiat that on a biomass basis, algae dominated the reef flat; they invoked the "traditional" trophic pyramid of biomass with 85% algae, 13.8% herbivores, and 1.1% carnivores. However, most striking was the finding that only about 20% of that algal biomass was symbiotic (6% was macroalgae and 73% algal turfs, borers, and crusts). The reef literature has grown enormously since that time, along with our understanding of reef metabolism and community structure and function. However, the basic picture has not changed. Algae directly or indirectly construct and determine coral reefs. They also possess the potential to alter the character of a reef, given natural or human perturbation involving nutrients or grazing. Stony corals (scleractinians) have evolved a mechanism that allows extremely high rates of calcification, but that greatly limits the area covered by coral tissue to the pinnacles of a framework. Algae occupy the lateral surfaces of the framework and fill its holes with more carbonate. Increased nutrients or reduced grazing cause a "phase shift" of community structure, wherein framework construction by corals is greatly reduced and macroalgae come to dominate. These matters, as we have come to understand them in the last 20 years, are reviewed.

It has been hypothesized that sensitivity to UV-B may contribute to the population declines of some species. To better understand the effects of ambient UV-B on embryo development and survival, embryos from three lower latitude (34 degree N), lower altitude (290 m) amphibian species were studied at natural breeding sites in the Santa Monica Mountains near Los Angeles, California. We compared embryonic development and hatching success in Hyla regilla, Hyla cadaverina, and Taricha torosa embryos exposed to ambient solar UV-B radiation with those shielded from solar UV-B. A large percentage of H. regilla embryos survived when exposed to and protected from UV-B. Neither hatching success nor rates of development were affected by solar UV-B. Conversely, H. cadaverina and T. torosa embryos displayed high rates of embryonic mortality when exposed to solar UV-B. Elimination of solar UV-B significantly increased hatching success in both of these species, but had no effect on rates of embryonic development. These data suggest that under natural conditions, solar UV-B radiation influences embryo survival in both Hyla cadaverina and Taricha torosa. Additional studies are required to determine whether susceptibility to UV-B affects these species at the population level.

However, when settlement is continuous or weakly seasonal, with patterns that vary both between species and within species among years, regular, sometimes year-round, recruitment surveys at intervals linked to short-term settlement dynamics are needed to quantify fluctuations in recruitment strength. Monthly recruitment surveys may be appropriate in the tropical northwest Atlantic, where settlement is often both lunar periodic, and broadly and variably seasonal. Use of a variety of recruit-census methods impedes comparisons of recruitment patterns and their demographic effects, because recruit densities and recruit:adult ratios cannot be directly compared when recruits (because they have widely varying post-settlement ages) have experienced very different levels of early post-settlement mortality. Examining the relationship between changes in adult populations and annual, end-of-season recruitment may be satisfactory for long-lived species with strong settlement seasonality and maturation times of approximately 1 year. However, it is inappropriate for short-lived, rapidly maturing species, particularly those that have broad and variable settlement seasons and whose populations fluctuate substantially throughout the year in response to short-term fluctuations in recruitment. Comparisons of demographic effects of recruitment among species with different longevity require the use of non-arbitrary time scales, such as the time to maturity and the adult half-life.

However, body size has substantial effects on processes that affect competitive relationships between species: (i) small, recently recruited fish, which usually(?) suffer high mortality, can dominate total abundance and strongly influence the dynamics of the relative total abundances of different species, while having little effect on interspecific biomass relations; (ii) numeric abundance and biomass of a species can vary independently, due to habitat variation in population size-structure resulting from variation in mortality and growth, as well as habitat selection; and (iii) population size-structure affects the potential for and outcome of interspecific competition due to (a) ontogenetic change in types of resources used, (b) levels of resource needs being dependent on individual and species biomass rather than numbers, (c) advantages due to large size in behavioural contests, (d) variation in population size-structure being linked to habitat preference, which affects expression of competitive dominance, and (e) size dependency in the development of interspecific resource-sharing relationships. Assemblage-level analyses that ignore such size effects may fail to detect important effects of interspecific interactions.

Pillow lavas from the Llanada Coast Range ophiolite remnant are mostly Cr-rich and TiO (sub 2) -poor basalts in which Ti does not increase with increasing Fe/(Fe+Mg); some Cr-poor siliceous rocks are also present. Most Llanada rocks are depleted in light rare earth elements (REE), although a few show slight light REE enrichment. Ti/V ratios are arc-like. The Llanada basalts appear to be island-arc tholeiites that have limited boninitic affinities--i.e., products of suprasubduction zone magmatism. Basalts from the Black Mountain Coast Range ophiolite remnant near St. Helena are TiO (sub 2) -rich relative to those from most other Coast Range ophiolite fragments, and TiO (sub 2) increases with increasing Fe/(Fe+Mg). Black Mountain basalts are light REE depleted, REE enriched overall relative to Llanada lavas, and have mid-oceanic-ridge basalt (MORB)-like Ti/V ratios. These characteristics are similar to those of MORB, but elevated Th/Ta ratios suggest a suprasubduction-zone origin for the Black Mountain lavas. These results show that the Coast Range ophiolite is highly diverse, containing island-arc tholeiites and possibly suprasubduction zone-related MORB-like components. In the Coast Range ophiolite as a whole, the apparent preponderance of island-arc tholeiite lavas such as those at Llanada over MORB-like lavas such as those at Black Mountain favors a forearc over a backarc setting for the origin of the ophiolite. Other data suggest that the Coast Range ophiolite locally contains ocean-island basalts (OIBs). Moreover, serpentinite-rich ophiolitic detritus overlying Coast Range ophiolite serpentinite suggests that, in some areas, the basaltic section of the oceanic crust was missing completely, and serpentinized harzburgite was exposed at the sea floor. These relationships are similar to those in the modern Mariana forearc, which exposes a complex amalgam of boninitic and arc-tholeiitic suprasubduction zone-related crust, MORB and OIB crust, and serpentinized harzburgite.

Toward this end, we quantified the responses to UV of Antarctic phytoplankton in the Weddell-Scotia Confluence during the austral spring of 1993. Experimental results on spectral sensitivity of photosynthesis were fit statistically to a model that incorporated uninhibited photosynthesis as a function of photosynthetically available radiation (PAR), wavelength-dependence of inhibition, and the kinetics of photosynthesis during exposure to UV. In contrast to previous results on UV-induced photoinhibition in a diatom culture at 20 degree C, natural phytoplankton from open waters of the Antarctic showed no ability to counter UV-induced inhibition of photosynthesis during exposures of 0.5-4 h: the rate of photosynthesis declined exponentially as a function of cumulative exposure, and inhibition was not reversed during incubations for up to 3.5 h under benign conditions. The results suggest that nonlinear exposure-response relationships are necessary for modeling UV-dependent photosynthesis in the surface mixed layer of the springtime Weddell-Scotia Confluence. Consequently, we modified our laboratory-based model of photosynthesis and photoinhibition to describe photoinhibition as a nonlinear function of biologically weighted cumulative exposure to damaging irradiance. The model described similar to 90% of the spectrally dependent experimental variation in photosynthetic rate, and yielded six biological weighting functions (BWFs) for phytoplankton in the Weddell-Scotia Confluence. Assemblages from different stations showed substantial variability in sensitivity to UV. Tolerance of UV was generally highest in assemblages from shallower mixed layers, which presumably had experienced higher irradiance, including UV, prior to sampling. The BWFs of assemblages that seemed acclimated to low irradiance showed the highest sensitivity to UV yet seen for Southern Ocean phytoplankton. The pattern of UV sensitivity was consistent with acclimation, but also with selection against less tolerant species.

Over a 14 mo experimental period, 5 closely spaced and shallow subtidal coral colonies were cored at 1 mo intervals. These cores were subsequently analysed to determine linear extension (growth) and the delta super(13)C and delta super(18)O of each monthly growth increment. Environmental conditions were recorded continuously by instruments deployed within a distance of 10 to 110 m from the corals. The environmental variables sea surface temperature (SST), salinity, wind, sun and rainfall were all well correlated with one another, reflecting the dominant seasonal cycle in the region. Of the 3 skeletal attributes considered in this study, skeletal delta super(18)O showed the strongest correlation with this seasonal cycle. The seasonal variations in skeletal delta super(18)O are attributed to changes in SST (accounting for ca 60% of the delta super(18)O signal) and inferred changes in water isotopic composition due to rainfall and runoff (ca 40% of the delta super(18)O signal). Although these results indicate that this coral is capable of yielding high-resolution paleoenvironmental records from retrospective analysis of the skeleton, there were significant and unexplained between-colony differences in mean delta super(18)O. Therefore, for this species of coral in this setting, great care must be taken before interpreting the regional environmental significance of either gradual changes in mean delta super(18)O through the length of a single long coral core, or differences between modern and ancient (fossil) colonies. Although skeletal delta super(13)C and growth rate did show some relatively weak but significant correlations with some of the environmental variables, especially when the records from all colonies were combined, it was concluded that these attributes have relatively low potential for regional paleoenvironmental reconstruction.

This within-lineage effect is not a sampling bias. It persists throughout the Cenozoic, accounting for the gradual overall increase in average mass (Cope's rule). The effect is stronger for larger mammals, being near zero for small mammals. This variation partially explains the unwavering lower size limit and the gradually expanding mid-sized gap, but not the sudden large increase in the upper size limit, at the Cretaceous-Tertiary boundary.

But to evaluate such effects, experimental results on, and existing models of, photosynthesis cannot be extrapolated directly to the conditions of the open waters of the Antarctic because vertical mixing of phytoplankton alters UV exposure and has significant effects on the integrated inhibition through the water column,,. Here we present a model of UV-influenced photosynthesis in the presence of vertical mixing, which we constrain with comprehensive measurements from the Weddell-Scotia Confluence during the austral spring of 1993. Our calculations of photosynthesis integrated through the water column (denoted P sub(T)) show that photosynthesis is strongly inhibited by near-surface UV radiation. This inhibition can be either enhanced or decreased by vertical mixing, depending on the depth of the mixed layer. Predicted inhibition is most severe when mixing is rapid, extending to the lower part of the photic zone. Our analysis reveals that an abrupt 50% reduction in stratospheric ozone could, in the worst case, lower P sub(T) by as much as 8.5%. However, stronger influences on inhibition can come from realistic changes in vertical mixing (maximum effect on P sub(T) of about c37%), measured differences in the sensitivity of phytoplankton to UV radiation (c46%) and cloudiness (c15%).

The organic shale is an upper bench of the Springfield Coal in an area where the coal is split into an upper and lower bench by a complex system of clastics that originated as a splay. The clastic wedge, described as the Folsomville Member/Leslie Cemetery paleochannel, is up to 6 km wide and 15 m thick. The transect begins approximately 100 m from the edge of the clastic wedge that splits the coal seam and follows the upper bench of coal over and toward the center of the clastic wedge. The dominant elements of the vegetation were the lycopsid tree Paralycopodites brevifolius and several species of medullosan pteridosperms. This report confirms the ecotonal habitats of this vegetation.

Columbite-group minerals with 1-3 wt.% Sc (sub 2) O (sub 3) are referred to as scandian columbite-tantalite and show degrees of structural order similar to columbite-tantalite lacking Sc. Disordered structures remain orthorhombic and become ordered upon heating. Pseudo-orthorhombic stannian (Sn-rich), titanian (Ti) and wolframian (W) variants of ixiolite may contain as much as 3.7 wt.% Sc (sub 2) O (sub 3) and revert to monoclinic phases upon heating. Similarly, scandian ixiolite that contains Sc in excess of 3.0 and up to 18.8 wt.% Sc (sub 2) O (sub 3) converts from orthorhombic to monoclinic symmetry upon heating and has a stoichiometry that approaches Sc(Nb, Ta)O (sub 4) . Scandium-bearing columbite-tantalite and ixiolite show similar ranges in Mn/(Mn+Fe) and Ta/(Ta+Nb) values, but noticeably different Sn, Ti and Sc contents. Scandium is incorporated into the columbite and ixiolite structures via the coupled substitution Sc (super 3+) +(Ti,Sn) (super 4+) = (Fe,Mn) (super 2+) +(Nb,Ta) (super 5+) ; it is strongly partitioned into the (Fe,Mn) site, whereas the Ti and Sn prefer the (Nb,Ta) site. Within the (Fe,Mn) site, the substitution of Sc for Fe is more prevalent. In most pegmatites, Sc fractionation in columbite-tantalite, stannian ixiolite, titanian ixiolite and wolframian ixiolite is erratic, unlike scandian ixiolite, which shows strong enrichment in Sc with increasing Mn, Ta and Sn.

It commonly constitutes the matrix containing either coarse lamellae of sarcopside, which in turn hosts fine lamellae of triphylite, or abundant lamellae of triphylite with bimodal size-distribution. Deformed and recrystallized granular aggregates of graftonite with triphylite, wolfeite and sarcopside are rare. Graftonite-beusite is systematically Ca,Mn-rich and Mg-poor relative to sarcopside, which in turn is slightly Mn-rich and distinctly Mg-poor relative to the Li-concentrating triphylite. Bulk compositions of the lamellar aggregates, crystal-chemical and textural relationships among the individual phosphates, and cation distribution-coefficients indicate two patterns of exsolution that generated the lamellar intergrowths from disordered homogeneous precursors: Ca,Li-poor graftonite exsolved lithian sarcopside, which in turn broke down to sarcopside with triphylite lamellae, and Ca,Li(Mn)-rich graftonite-beusite exsolved triphylite directly. In regional zoning of pegmatite groups, Ca-bearing graftonite-beusite is either the first Fe,Mn(Li)-phosphate encountered in the beryl-columbite pegmatites, or it is found within the zone of beryl-columbite-triphylite pegmatites. Appreciable concentrations of Ca, Fe, Mn (and in part Mg), but low levels of F and Na, are required to stabilize graftonite-beusite. Good correlation of the Mn/(Mn+Fe) values of the phosphates with those of garnet suggests that the homogeneous graftonite-beusite precursor could have been generated by phosphorus-induced destabilization of garnet.

This assemblage is the Fe, Mn, Nb, Ta-rich counterpart of the Ti-dominant niobian rutile+exsolved titanian columbite pair. The rutile phase is enriched in Fe (super 2+) , Ta, Fe (super 3+) and Sn, whereas the orthorhombic phase favors Mn, Nb, Sc, W and Zr. Most samples of the orthorhombic phase are defined as titanian columbite - tantalite; they have low to moderate Ti content, moderately to considerably disordered structure, and convert to highly ordered columbite-tantalite on heating. A minor number of samples of the orthorhombic phase develops the highly ordered structure of wodginite on heating, which identifies them as titanian ixiolite, the disordered counterpart of titanowodginite. These samples are highly disordered in the natural state. They are Ti-rich, with Mn>Fe and Ta>Nb; these features correspond to the composition of natural titanowodginite and of the only titanowodginite synthesized to date. However, subordinate but significant Sn seems to be present in all samples of titanian ixiolite as well as natural titanowodginite, and it may affect the path of ordering. Excess of Ta over the (Fe, Mn)(Nb, Ta) (sub 2) stoichiometry of columbite, characteristic of most compositions of wodginite, may play a significant role.

The eggs occur as compact, rounded masses and as irregular sheetlike or unilayered aggregates, some of which cover plant remains to which they may have been attached originally. Individual eggs consist of a compressed central body surrounded by a thin, apparently flexible membrane, and an outermost halolike covering. Characteristics of the egg masses and the morphology of individual eggs are indistinguishable from those of modern anuran amphibians. Because dissorophoid temnospondyls are phylogenetically related closely to Recent amphibians and are well represented in the Lower Permian of north-central Texas, dissorophoids are the most probable source of the eggs.

However, this relationship has rarely been tested directly. The offspring sex ratios produced by pollinating fig wasp foundresses upon entrance to a fruit and oviposition alone (single foundress sex ratios) are subject to stabilizing selection because too many males reduce the total number of dispersing females and too few males will result in unmated females or complete loss of the brood. Furthermore, we argue that the impact on fitness of, and therefore the intensity of stabilizing intensity on, single foundress sex ratios are correlated to how frequently a species produces single foundress broods in nature. Specifically, the intensity of stabilizing selection will be greater in species that encounter single foundress broods more frequently, both because the trait is expressed more often and because fitness shows a greater sensitivity to variation (narrower fitness profile) when that trait is expressed. Across 16 species of Panamanian pollinating fig wasps, (Agaonidae), the phenotypic variance in single foundress sex ratios was negatively correlated with the frequency with which that species encounters single foundress broods in nature. In addition, a formal comparative analysis based upon a molecular phylogeny of the wasps gave results that were the same as when species were used as independent data points.

The islands subside and erode as the plate carries them to the north-west, eventually to become coral atolls and seamounts. Thus islands are ordered linearly by age, with the oldest islands in the north-west (e.g. Kauai at 5.1 Ma) and the youngest in the south-east (e.g. Hawaii at 0.43 Ma). K-Ar estimates of the date of an island's formation provide a maximum age for the taxa inhabiting the island. These ages can be used to calibrate rates of molecular change under the following assumptions: (i) K-Ar dates are accurate; (ii) tree topologies show that derivation of taxa parallels the timing of island formation; (iii) populations do not colonize long after island emergence; (iv) the coalescent point for sister taxa does not greatly predate the formation of the colonized younger island; (v) saturation effects and (vi) among-lineage rate variation are minimal or correctable; and (vii) unbiased standard errors of distances and regressions can be estimated from multiple pairwise comparisons. We use the approach to obtain overall corrected rate calibrations for: (i) part of the mitochondrial cytochrome b gene in Hawaiian drepanidines (0.016 sequence divergence/Myr); (ii) the Yp1 gene in Hawaiian Drosophila (0.019/Myr Kambysellis et al. 1995); and (iii) parts of the mitochondrial 12S and 16S rRNA and tRNA super(val) in Laupala crickets (0.024-0.102/Myr, Shaw 1996). We discuss the reliability of the estimates given the assumptions (i-vii) above and contrast the results with previous calibrations of Adh in Hawaiian Drosophila and chloroplast DNA in lobeliods.

To decipher the relative importance of biological characteristics vs. environmental conditions, it is necessary to ask whether groups of taxa with similar distributions share the same history of diversification. Because all of the taxa will have shared the same climatic and geological history, evidence of shared history across multiple species provides an estimate of the role of extrinsic factors in shaping contemporary biogeographic patterns. Similarly, differences in the records of evolutionary history across species will probably be signatures of biological differences. In this study, we focus on inferring the evolutionary history for geographical populations and closely related species representing three genera of primary freshwater fishes that are widely distributed in lower Central America (LCA) and northwestern Colombia. Analysis of mitochondrial gene trees provides the opportunity for robust tests of shared history across taxa. Moreover, because mtDNA permits inference of the temporal scale of diversification we can test hypotheses regarding the chronological development of the Isthmian corridor linking North and South America.

However, some species are found on both sides of the EPB. These 'transpacific' species are considered by 'dispersal' biogeographers as evidence of invasions through the barrier. 'Vicariance' biogeographers, on the other hand, think that transpacific species are morphologically conservative remnants of previously continuous distributions. We compared nucleotide sequences in a 642 bp region of mitochondrial DNA, and elctrophoretically detected alleles in 17 enzymatic loci of central and eastern Pacific populations of Echinothrix diadema, an Indo-Pacific sea urchin recently reported from the eastern Pacific. Both types of molecules produced clear evidence of massive, recent gene flow across the EPB. Thus, rather than being isolated relicts of Tethyan distributions, conspecific populations from the eastern and central Pacific are genetically connected. Though the EPB is biogeographically important as a cause of speciation in many groups, it allows genetic connections in others, possibly through larval transport during El Nino events.

An earlier skeletochronological analysis (Zug and Balazs, 1985) of a small sample suggested that in Hawaii, large juveniles to adults might be as old as 43-81 years. A larger sample salvaged since 1991 to examine the effects and onset of fibropapillomas also permits us to use skeletochronology to estimate the ages of these turtles. Skeletochronology is based on the reptilian aspect of skeletal growth by appositional deposition of new bone on old. This periosteal growth is cyclic, producing discrete bony layers in response to environmental and/or physiological cycles. The number of layers serves as an age index, and we assume that each layer represents one year of growth, i.e., the number of layers equals the estimated age of the turtle in years.

An extraordinary cold snap in December 1989 cause a major cold-stunning event in the lagoon. Over 150 seaturtles were rescued and their rehabilitation attempted. About one third of the C. mydas did not survive the cold-shock; these turtles offered an opportunity to use skeletochronology to estimate their ages and examine the age structure of C. mydas in this developmental habitat. The sample contains individuals ranging from 28-74 cm SCL with estimated ages of 3-14 yr. The age estimates suggest the following hypothetical life cycle for Florida-Atlantic Chelonia mydas. The pelagic phase lasts a minimum of 3 years, although 5 to 7 years is the most likely common duration. The juveniles then return to coastal water (nearshore and estuarine habitats) and join foraging assemblages in developmental habitats. Individuals remain in these developmental habitats for 6-10 years, although likely not at the same locality, and depart these habitats for subadult-adult feeding grounds somewhere in the Caribbean at ages of 12-14 yr and at 60-75 cm SCL.

We use whole-rock and mineral elemental compositions, along with standard and cathodoluminescence petrography to characterize alteration histories of Late Triassic to Middle Jurassic metavolcanic rocks in the Ritter Range, White-Inyo Mountains, and Alabama Hills. Although alkali-metasomatism is widespread and pervasive, ratios and abundances of Ce, Th, Tb, and Ta suggest that mafic protoliths from the White-Inyo Mountains were shoshonitic, whereas those from the Ritter Range were calc-alkaline. Alkali exchange apparently modified the compositions of many metavolcanic rocks. Much of this metasomatism may have occurred at low-temperature (T) conditions, and attended or shortly postdated deposition of the volcanic protoliths. High delta (super 18) O values for K-rich metatuffs from the Ritter Range suggest that the K-metasomatizing fluid was low-T seawater. In contrast, low delta (super 18) O values for K-rich metatuffs from the Alabama Hills and Inyo Mountains seem to reflect rock interaction with meteoric water prior to contact metamorphism. Jurassic metatuffs deposited in marine (Ritter Range) and nonmarine (Alabama Hills, Inyo Mountains) settings display similar degrees of K for Na (or Ca) exchange that were affected by isotopically distinct fluids. Some alkali-metasomatism of Jurassic metavolcanic rocks is related to Cretaceous plutonism. In the Ritter Range and Alabama Hills, these effects are localized around pluton contacts, appear to be more vein related than pervasive, and overprint K-metasomatized assemblages.

Within the oldhamite ( approximately 5 vol% of the oldhamite) are a variety of phases, including osbornite (TiN), titanoan troilite (17.2-25.2 wt% Ti), heideite (28.7-29.4 wt% Ti), niningerite, daubreelite, forsterite, and Fe metal. This clast represents only the second occurrence of an oldhamite-rich lithology in aubrites. An igneous origin for oldhamite within the Bustee pyroxene-oldhamite clast is suggested by its large size, rounded shapes, presence of included phases formed from multiple, immiscible sulfides, and inclusion of phases unknown from enstatite chondrites. The Bustee clast contains a variety of Ti-rich phases. This work suggests Ti-rich troilite observed in aubrites formed by co-crystallization with or exsolution from Ti-poor sulfides (e.g., oldhamite). In the Bustee case, the undetectably low Ti concentrations in oldhamite and experimental Ti partition coefficient between FeS and CaS approaching infinity support such a suggestion. This mechanism solves the longstanding problem of enriching aubritic troilite in Ti and weakens arguments against a direct derivation of aubrites from known enstatite chondrites.

At the study site in Lowes Cove, Maine, USA, Casco bigelowi occurred in highest densities in soft sediments just below mean low water (MLW). During most months, the sex ratio was 1. Many females hosted males in their burrows throughout the summer, but after fertilization of females in September, all adult males disappeared from the study area. In October almost 80% of the females were ovigerous, and in November about the same percentage was parental, i.e. caring for juveniles in their burrows. The females produced only one brood each in late fall which they accommodated in their burrows for 2 mo or longer. The average number of juveniles per female was similar to 20 in November, and continuously decreased until January. Juveniles reached sizes >10 mm length in the maternal burrows. In early December the first juveniles were found in their own burrows, but major recruitment took place in late December and January. It is concluded that for C. bigelowi, the delay of recruitment into the winter months with low predation pressure and the large offspring size at this time are major advantages gained by extended parental care. C. bigelowi is host to the peritrich ciliate Cothurnia sp. on its gills, and during the summer months >70% of all amphipods had ciliates on their gills. Juveniles still living in their mother's burrows showed infestation rates similar to that of the parent; those of highly infested mothers were more heavily infested than those of "clean" mothers. Facilitated epibiont transmission during intimate and long-lasting (2 mo) parent-offspring associations may be a consequence of extended parental care.

However, glacial Amazon climates were colder and had reduced CO sub(2) concentrations that would have had their strongest effects on the biota in the elevated areas stipulated to have been refugia. If local endemicity of butterflies or birds records Pleistocene speciation, this is because glacial climates provided cool, CO sub(2) starved islands in a sea of continuous forest.

Nonetheless, seed distribution patterns for pioneers are poorly known, and processes controlling the fate of seeds in the soil have been little explored. We examined patterns of seed rain, seed abundance in the soil, and seed mortality of two common pioneer trees, Miconia argentea (Melastomataceae) and Cecropia insignis (Moraceae), on Barro Colorado Island, Panama. For each species, we selected four isolated, reproductive trees within a 50-ha forest dynamics plot. Seed rain and soil seed bank samples were collected, respectively, in mesh traps and from soil cores sampled along transects radiating away from the tree crowns. At below-crown sites, seed rain inputs far exceeded soil seed bank densities measured at the end of the fruiting season. For Miconia, the below-crown seed bank in the surface 3 cm of soil accounted for only 23% of seed rain, and for Cecropia, only 2%. However for Miconia, at distances >5 m from the crown seed bank densities exceeded the annual seed rain input. For both species log seed densities in the seed bank declined linearly with log distance from the crown and also decreased dramatically through the year. The annual loss rate of Miconia seeds was >90% below the crown and declined to 65% at 30 m from the crown. The annual loss rate for Cecropia was >90% at all distances. Seed losses in the seed bank could be largely attributed to mortality from pathogenic fungi. Fungicide treatment significantly increased seed survival in the soil for both species. For these two gap-dependent pioneer species, rapid seed-bank turnover rates and logarithmic declines in soil seed density with distance from adults suggested that both the spatial distribution and timing of gap formation may have influenced their chances of successful gap colonization. Recruitment from distant seed sources, or from seeds surviving in the soil after the death of the parent tree, may be relatively rare for these species.

These rodents and their complex towns have been the bane of ranchers and developers throughout the West, but are now garnering the interest of wildlife fans and conservationists. The Alliance collects the prairie dogs to deliver them to a protected preserve. Only two of the five species of prairie dogs are protected by law, and the populations of the others are declining. At one time prairie dog populations reached over five billion, in towns that covered up to 250 million acres. Eradication programs and land use conversions have reduced the total population to about one and a half million.

At depths exceeding 25m, these 13 species are interpreted as relict markers of former low sea-level stands of latest Pleistocene-to-Holocene age. Their concentration in coast-parallel belts also records the role of seafloor erosion by Holocene to modern bottom-current activity, and also displacement by bioturbation. Widespread distribution of reworked molluscan faunas and low rates (to <3 cm/1000 years) of sediment accumulation mapped on many parts of the shelf and upper slope record the overall sediment-starved nature of the Nile shelf. Where now concentrated in deep-water environments, infralittoral molluscs serve as markers to help define effects of the Holocene transgression, denote zones of intense erosion and biogenic reworking, and interpret both relict and reworked relict (palimpsest) patterns on the modern Nile shelf.

We have studied the sediments and fossil plant assemblages of three laterally extensive carbonaceous beds from the Eocene of the Bighorn Basin, Wyoming. Field, laboratory, and microscopic observations show that carbonaceous beds are highly heterogeneous, varying in the amount and type of organic matter, preservation of primary sedimentary structures, and the prevalence of paleosol features. Small-scale lateral and vertical variations indicate a mosaic of conditions in the wet floodplain backswamp. The variables controlling this mosaic were primarily rate of clastic input and degree of substrate flooding which, in turn, influenced the amount of pedogenesis. Fossil plant assemblages occur in sediments least modified by pedogenesis, and the best preservation is in the distal, fine-grained portions of overbank flood deposits. There is no evidence for transport of plant material from channel to backswamp. Fossil leaves in a single quarry sample (i.e., those collected from within 10-20 cm stratigraphically and from an area of 4-10 m (super 2) ) probably accumulated during one or several closely-spaced flood events. Quarry samples are thus spatially and temporally constrained "snapshots" of the vegetation that grew on the alluvial floodplain. Each carbonaceous bed is estimated to represent roughly 2,000 years, based on the length of fluvial avulsion cycles. Multiple quarry samples from the same carbonaceous bed can thus be considered coeval for most evolutionary or paleoclimatic analyses. In the central Bighorn Basin, laterally extensive carbonaceous beds are abundant in the lower and upper Willwood Formation, but essentially absent in the middle. We attribute this to tectonic and climatic change, especially to higher rates of sediment accumulation that caused greater dispersal of organic material within sediments and climatic drying that allowed degradation of organic material before it could be preserved.

Wollastonite replaces calcite + quartz on a layer-by-layer basis in homoclinal, near-vertical beds. At the peak of metamorphism (P approximately 1500 bar, T approximately 600 degrees C), fluid in equilibrium with this assemblage has the composition X (sub CO) (sub 2) 0.28, requiring that the wollastonite-forming reaction was driven by infiltration of reactive H (sub 2) O-rich fluid. The spatial distribution of this mineral assemblage records that peak metamorphic flow was layer-parallel, upwards. EPMA results are reported for calcite, dolomite, wollastonite, diopside, forsterite, amphibole, biotite, plagioclase, K-feldspar, garnet, spinel, clinozoisite, chlorite and serpentine. Bounds on the prograde time-integrated fluid flux are set by: 1) the overlap in delta (super 18) O values between wollastonite-bearing and wollastonite-free rocks (> 245 mol fluid/cm (super 2) rock), 2) the amount of fluid that would drive the wollastonite-reaction front upwards to the present level from a depth where calcite, quartz and wollastonite would be in equilibrium with pure CO (sub 2) (<< 1615 mol/cm (super 2) ). Back reaction of wollastonite to calcite + quartz records an additional time-integrated retrograde fluid flux of approximately 200-1000 mol/cm (super 2) . Fingers of wollastonite-bearing rock that extend furthest from the fluid source along contacts between limestone and more siliceous rocks point to strong control of flow geometry at the 0.1-100 m scale exerted by pre-metamorphic structures.

The RMS residual with respect to the best fitting lines through the individual station position estimates is 2-3 mm in the horizontal and 6-10 mm in the vertical. After the first 395 days of operation, uncertainties in horizontal velocity estimates are 1-2 mm/yr (1-sigma ). Relative motion among NBAR sites located in eastern Nevada and in Utah is small, but east-west extension is significant assuming uniform strain accumulation across the whole network. The relative motion observed across the Wasatch fault zone is 2 + or -2 mm/yr, east-west. Relative motions among stations in western Nevada and California, in contrast, are dominated by northwest, right-lateral shear. We infer an integrated deformation across the northern Basin and Range of 11 + or - 2 mm/yr, northwest. These rates are consistent with previous geodetic measurements. Our GPS velocity estimates, however, reveal a possibly abrupt transition from east-west extension in eastern Nevada and Utah to right-lateral shear in western Nevada. This transition is roughly coincident with the central Nevada seismic belt and is consistent with the right-oblique focal mechanisms of the 1954 Dixie Valley and Fairview Peak earthquakes. The transition also appears to correlate spatially with a transition in upper mantle structure. Copyright 1998 by the American Geophysical Union.

Fledglings' mean ( plus or minus SE) age at dispersal from the natal sites was 32.5 plus or minus 0.6 days post hatching. First dispersal sites were located 1.5 plus or minus 0.3 km from the natal site. All young joined flocks of juveniles, except three birds that remained solitary. Sixteen birds stayed at the first dispersal site until departure on migration, whereas nine visited additional dispersal sites. On 40 occasions, 15 fledglings moved up to 6 km from their dispersal sites. Before late August, 96.7% of fledglings' locations occurred in: (1) second growth scrub/deciduous sapling sites located along forest borders and abandoned farms (59.4%), (2) gypsy moth (Lymantria dispar) damaged deciduous forest (24.4%), and (3) Virginia pine (Pinus virginianus) forest with heavy deciduous understory (12.8%). Fruiting trees and shrubs used as food sources by juveniles fruit earlier in these habitats. After late August, an increased number of fledgling locations (14.1%) occurred in mature deciduous or mixed forest, possibly tracking the later fruiting cycles of understory plants in these habitats. Twenty-four of 33 fledglings left the study area in September. Mean age at departure was 81 plus or minus 5 days post hatching. We suggest that postfledging movements in Wood Thrushes are keyed by the availability of food resources and the presence of conspecifics, although other factors may play a role. We conclude that successful conservation of migratory species requires protection of habitats used during the postfledging period as well as those used during the nesting portion of the life cycle.

Populations of L. laevigata sampled from Thailand and South Africa, where an orange color morph predominates, were surveyed using seven polymorphic enzyme loci and restriction fragment analysis of a portion of the mtDNA including the control region. Both allozyme and DNA data demonstrated that these populations were significantly genetically differentiated from each other and to a greater degree from 23 populations throughout the West Pacific Ocean, where a blue color morph is predominant. The genetic structure observed in L. laevigata is consistent with traditional ideas of a biogeographic boundary between the Indian and Pacific Oceans except that populations several hundreds kilometers off the coast of north Western Australia (Indian Ocean) were genetically similar to and had the same color morphs as Pacific populations. It is suggested that gene flow may have continued (possibly at a reduced rate) between these offshore reefs in Western Australia and the West Pacific during Pleistocene falls in sea level, but at the same time gene flow was restricted between these Western Australian populations and those in both Thailand and South Africa, possibly by upwellings. The molecular data in this study suggest that vicariant events have played an important role in shaping the broadscale genetic structure of L. laevigata. Additionally, greater genetic structure was observed among Indian Ocean populations than among Pacific Ocean populations, probably because there are fewer reefs and island archipelagos in the Indian Ocean than in the Pacific, and because present-day surface ocean currents do not facilitate long-distance dispersal.

The committees promote lion tamarins as "flagship" species, the ultimate intent being the preservation of the unique Atlantic rain forest (Mata Atlantica) ecosystem and its many endemic plants and animals. We summarize the history, organization, structure, and functioning of these oversight management committees and their current role in guiding, motivating, and focusing conservation efforts for the Mata Atlantica of Brazil and the four endangered Leontopithecus species therein. We discuss the role of science in conservation planning for the species, funding mechanisms, the decision-making process, conflicts and their resolution, and criteria used for evaluating success. The benefits of this particular species recovery process include the establishment of collaborative partnerships between the Brazilian government and a multitude of individuals and organizations and the use of multidisciplinary, semi-autonomous teams to implement conservation activities. The major limitation of the management committees is their lack of a formal budget and permanent staff. JF - Conservation Biology AU - Kleiman, D G AU - Mallinson, JJC AD - Natl.

Profiles of wildlife rehabilitators in various states illustrate the practices adopted by these devotees and the diversity of wildlife they respond to. Typical patients include fledgling crows, raccoons, rabbits, swifts, owls, opossums, and other species that cross the borders between wilderness and urban areas. Rehabilitators must have permits, generally based upon an apprenticeship, exams, appropriate facilities, and fees. Rehabilitators carefully track and report on their activities. While 3500 rehabilitators now operate with federal permits, about 30,000-50,000 are estimated to be active in the field, often working with licensed rehabilitators. Although their work contributes little to wildlife conservation, rehabbers play an important role in the public awareness and acceptance of conservation issues.

This phenomenon has only recently been documented, and forms an important component of scientific understanding of coral reproduction and ecosystem health. Although coral reefs may be massive in size, these ecosystems sustain only a thin shell of life on the skeleton, and are highly vulnerable to pollution and environmental changes. Thus, reefs that lie near the shores suffer from runoff and pollutant discharges. Coral reef biologists studying the reproductive patterns note the effects of the full moon, timing after nightfall, and seasonal patterns. The egg bundles are highly vulnerable to numerous predators.

AN - 79628483; 9406195 AB - Spermatozoa from teratospermic domestic cats (> 60% morphologically abnormal spermatozoa per ejaculate) consistently exhibit lower levels of oocyte penetration in vitro than their normospermic ( 0.05). Preincubation with either inhibitor reduced tyrosine phosphorylation of both (95- and 160-kDa) sperm proteins. Although both inhibitors blocked the ZP-induced AR, neither influenced the spontaneous AR nor the A23187-induced AR, suggesting that tyrosine phosphorylation may be involved in physiologic AR. No differences (P > 0.05) were observed in the ability of control or inhibitor-treated spermatozoa to bind to or penetrate the outer ZP layer. However, percentages of oocytes with treated spermatozoa in the inner ZP (tyrphostin, 8.7%; genistein, 20.4%) and perivitelline space (tyrphostin, 0%; genistein, 2.3%) were less (P < 0.001) than untreated controls (inner ZP, 62.7%; perivitelline space, 10.2%). These results (1) demonstrate that ZP-induced acrosomal exocytosis in domestic cat spermatozoa is regulated via a tyrosine kinase-dependent pathway and (2) suggest that defects in these signaling pathways may represent one of the causes for compromised sperm function in teratospermic males.

Several years ago, a very broad iron emission line was discovered in the active galaxy MCG-6-30-15, indicative of emission from an accretion disk near the event horizon of a black hole. But this interpretation, based on the line profile, was somewhat model dependent (refs 2-5). Here we present an analysis of the iron-line emission from MCG-6-30-15 that is insensitive to the details (for example, diskthickness and emissivity) of the disk model used. We find that the inner edge of the disk material giving rise to the line is within 2.6 c 0.3 times the Schwarzschild radius--the event horizon of a non-rotating black hole--at the 95% confidence level. Changes to the disk parameters can only decrease the inner radius of the emitting region, and so we can be confident that we are observing emission from gravitationally bound material in the strong-field region of a supermassive black hole. Moreover, we find that the black hole is rotating at a rate which is \[gsims]23 c 17% of the theoretical maximum, although this conclusion is model dependent.

The validity of these generalizations, structured as hypotheses, is tested with four case studies from Costa Rica, Mexico, Venezuela, & Brazil. The first generalization is that tensions arise between international environmentalists principally concerned with wildlands conservation & national environmentalists engaged in a broader array of local & domestic issues including urban environmental quality & access to natural resources. The second is that environmental groups in Latin America are elitist in structure & participant base. The third is that particular tactics employed by environmentalists will be closely tied to the relative openness of their nation's political system. Through a cross-disciplinary case study approach we find the first two hypotheses quickly break down upon closer inspection, while the third is supported. We suggest a modified framework for interpreting environmental activism in the region, one that weighs the role of the state as well as competing strategies employed by grassroots, private voluntary, & professionalized environmental groups. Latin American environmentalism is highly diverse, presenting many faces in different time periods & different countries. Developing one general theory of environmentalism in Latin America is impossible, but more specific categorization of the middle range may be achievable. 50 References.

Modelling indicates 13 + or - 5% melting where seafloor spreading occurs to 28 + or - 8% melting for the rift axis where more water was added to the mantle. The degree of mantle melting = 0.44% water in the mantle + or - 0.07. The authors consider whether arc and back-arc basin igneous activity coexist, variations in melt generation along extensional axes and the composition of lavas erupted during the earliest stages of back-arc basin formation. Major, trace, REE and isotopic (Pb, Sr, Nd) analyses of basalt, basaltic andesite, andesite, dacite and rhyolite are given.

Perclara Loeblich and Tappan (senior synonym of G. reissi Loeblich and Tappan), Globigerina pauciloculata Jenkins, and Candeina antarctica Leckie and Webb are Cenozoic species interpreted to have been adapted to a planktic habitat. Their restriction, however, to shallow marine or marginal marine paleoenvironments suggests that they were benthic species. These taxa are associated with reduced planktic foraminiferal diversity, a low P/B (planktic/benthic) ratio, and an inner shelf benthic foraminiferal biofacies. A new genus, Praepararotalia, is erected for several species interpreted to be phylogenetically related to the benthic genus Pararotalia. Praepararotalia cretacea (new species), which is described from the Maastrichtian Navesink Formation in New Jersey, gave rise to the early Paleocene species Praepararotalia perclara. In addition, stable isotopic (delta (super 18) O and delta (super 13) C) signatures of all praepararotaliid species in this study cluster closer to benthic foraminiferal signatures and are distinct from normal marine planktic taxa from the Cretaceous and the Paleocene. A benthic paleohabitat is suggested for the Danian species Antarcticella pauciloculata (Jenkins) because of its dominant occurrence in shallow facies of marginal basins in the southern high latitudes. The species may be phylogenetically linked to P. cretacea n. sp. and is apparently the stem taxon of a Southern Ocean Paleogene evolutionary lineage that includes A. cecionii (Canon and Ernst), A. zeocenica (Hornibrook and Jenkins), and A. antarctica (Leckie and Webb).

This geochronologically confirmed hypothesis shows that first and last appearances in different parts of the continent are highly diachronous. Additional results show that (1) despite this diachrony, the new event sequence is compatible with a previously hypothesized sequence of immigrant first appearances; (2) immigrant genera are not particularly widespread, abundant, or synchronous in their appearances; (3) last appearances, large-mammal appearances, and species-level appearances are the most reliable; and (4) most of the observed diachrony appears to result from undersampling. Because diachrony has little effect on the overall multivariate analysis, and because the differences among classes of events are not extreme, joint analyses of all known appearance events are preferable to the a priori selection of particular appearance events as time indicators.

We quantitatively tested this "ecological refuge paradigm" at a unique stromatolite-reef complex at Stocking Island, Bahamas where three contiguous zones grade in dominance from stromatolites in the back reef to a macroalgal turf in the reef flat to reef building corals and coralline algae and reef fishes in the fore reef. At two independent transects along this gradient, we quantified the distribution and abundance of the dominant organisms and measured the rates of the above-listed ecological processes and determined survival and growth of stromatolite, turf, and coralline algae transplanted to each of the three zones. We also measured both the sediment dynamics and temperature profiles along this gradient to determine if these may be controlling the ecological processes. Stromatolites dominate the back reef zone where species diversity (especially among eukaryotes) and associated ecological pressures were low. Measured rates of colonization from calcified (i.e., coralline) and noncalcified macroalgae and filamentous turf algae were lowest in the back reef (i.e., <5% substrate colonization/y) and highest in the fore reef (95% substrate colonization/y). This suggests that competition for space was lowest in the stromatolite zone. Growth and survival rates of transplanted coralline algae were low in both the back reef (3 mm/y and 20-40% annual survival rates) and reef flat (<2 mm/y, 0% surviving) and highest in the fore reef (about 10 mm/y, 80% surviving). Foraging activity from all fishes was lowest in the back reef (total 0.4 bites/m (super 2) /h) and reef flat (0 bites/m (super 2) /h) and highest in fore reef (900-2200 bites/m (super 2) /h, mostly from omnivorous wrasses). Herbivory from all potential sources was below detectable levels in the stromatolite zone and was highest in the fore reef. The ecological refuge found in the back reef stromatolite zone resulted primarily from periodic sediment inundation. Most eukaryotic reef-dwelling organisms cannot persist under as much as 700 mm of sediment for periods up to 100 days. Although the reef flat suffered both desiccation and thermal stress (averaging more than 5 degrees C greater daily temperature fluctuation than the fore reef), natural and transplanted eukaryotic turf algae thrived there. Although transplanted stromatolites survived best in the back reef (about 80% of the original transplant surviving/y), they also persisted in the fore reef (about 40% surviving per year). Therefore, Schizothrix-dominated stromatolites can persist in fore reef environments but because of the presence of other organisms and associated ecological pressures, their laminated microbial-produced structure is lost or obscured. While the sediment and the organisms necessary for stromatolite formation exist in this and probably in other modern reef environments, their reef-building contribution will be low except in unusual habitats where abiotic stresses maintain an ecological refuge.

As they deepen, higher waves will propagate into back-reef areas, altering the ecological and sedimentological zonation patterns and accelerating the erosion of leeward shelves and shores. Resuspended sediment will increase the turbidity, causing the demise of sediment-sensitive corals and possibly entire reef communities.

This pattern of discontinuous growth naturally leads to size distributions that are clustered into instar groupings. Since instars are natural units in arthropod development, the assignment of specimens to their correct instar may be important for studies of growth trajectories and their evolution. When these clusters do not overlap appreciably, inferring instar groupings is straightforward. In cases where there is overlap, there are no generally accepted methods to statistically compare different hypotheses of instar grouping. We present such a method in the context of maximum likelihood estimation, and demonstrate its application to data from two trilobite species. The basic assumption of this model is that size measurements are normally distributed within instars. An ontogenetic series with, for example, five instars is therefore considered a mixture of five normal distributions. For such an analysis using one size variable, 15 parameters would be estimated: the mean and variance of the variable for each of the five instars, and the proportion of the total distribution that each instar represents. Different hypotheses of instar groupings may then be compared based on their relative probability of producing the observed data. Since the likelihood of a model will necessarily increase with the number of groups in the model, we used parametric bootstrapping to assess whether improvements in likelihood exceed that which would be expected simply due to the addition of parameters to the model. Our analyses yield estimates of the mean and variance of all groups for all variables, and probabilistic assignments of each specimen to instar groups. The discrimination of instars from size distributions is a matter of biology and statistics; the method we present gives researchers a tool to evaluate statistical aspects of the problem.

However, terrestrial plants and vertebrates are preferentially preserved under very different taphonomic conditions, and diverse fossil floras and faunas are rarely found in close association. Big Multi Quarry and associated strata in the uppermost Fort Union Formation of the Washakie Basin, southwestern Wyoming, provide a uniquely detailed record of terrestrial fauna, flora, and climate during the early Clarkforkian. The Clarkforkian Land Mammal Age, approximately the last million years of the Paleocene, was an interval of global warming that had profound biotic consequences. The mammalian fauna of Big Multi Quarry, consisting of 41 species, is the most diverse known from a single Clarkforkian locality. Unlike most other Clarkforkian faunas, the Big Multi Quarry assemblage is not significantly biased against small forms. Lipotyphlan insectivores were dominant, and arboreally adapted taxa were abundant and diverse. The closely associated and well-preserved fossil plant assemblage was overwhelmingly dominated by a single species belonging to the birch family. Floral richness, heterogeneity, and evenness were as low as in the Tiffanian of the same region, showing that forest structure remained monotonous even as climate warmed and mammals diversified in the Clarkforkian. The plant assemblage more closely resembles middle than early Clarkforkian floras of northern Wyoming, suggesting northward migration of the ranges of plant taxa coincident with warming. A great deal of research has focused on the unusually warm interiors of continents in the terminal Paleocene and early Eocene. Multiple lines of evidence from our study, including sedimentological indicators, analyses of the nearest living relatives and functional analogues of the fossil plants and animals, size and margin analysis of fossil leaves, and cenogram analysis of the mammalian fauna, indicate that well before the terminal Paleocene southwestern Wyoming had a humid subtropical climate with little or no seasonal frost or marked dry season.

The sharp excursion in carbon isotopes near the Permo-Triassic boundary has been constrained to less than 160,000 years, and perhaps as little as 10,000 years. The isotopic shift has previously been shown to be global, occurring in both marine and terrestrial settings, to involve both organic and carbonate carbon, and to have occurred during an interval of marine transgression. The global signal involves a shift from +2-3 to -2 per mil (relative to PDB) and a return to near 0 in the early Triassic. But closely spaced sampling from the Meishan section, South China, suggests a transient drop as low as -6 per mil (Xu and Yan). These constraints on the duration of the extinction and the isotopic excursion allow us to model possible causes of the isotopic shifts, and thus test suggested causes of the mass extinction. Further analysis of this event will require statistical analysis of paleontological data.The carbon shift could have involved the whole ocean, as often assumed, the surface waters, or be a composite of both whole ocean and surficial effects, as originally suggested by Holser. Data from deep-water carbonates (Isozaki) indicates that much of the shift involved the whole ocean, although these data have not shown the abrupt shift seen in shallow marine and terrestrial settings. We have modeled the volume of carbon required to produce the observed shift under a variety of conditions. Although the Siberian flood basalts did erupt during the extinction interval, volcanic carbon is too heavy to have been involved. The deep-water carbon shift rules out a Strangelove ocean as the primary cause. Methane is a plausible source, but is difficult to release during marine transgression unless the surface waters experienced considerable warming (from the Siberian volcanism or an impact, for example). Onshore migration of a dysaerobic layer appears unlikely to have contained the 3000+ gigatons of carbon required to drive the isotopic shift. Given these considerations the most plausible sources of carbon for the observed shift are some form of oceanic overturn, global cooling then warming induced by the Siberian traps leading to methane release, or the impact of an icy body (comet).

Recovery in the Middle to Late Triassic is documented by reappearance of diverse plant assemblages composed of taxa related to but distinct from those of the Permian, suggesting evolution from extinction survivors in remote areas during the Early Triassic. Here we report the discovery of Early Permian floras from Knox and King Counties, north-central Texas, composed largely of genera typical of the Mesozoic. The floras come from the Blaine Formation of the Pease River Group, a gypsum-rich, sabka deposit that formed under strongly seasonally dry climate. Plants are preserved in mud-filled, channel-form deposits. They are among the youngest known Permian plants in North America and include the following elements: Dioonitocarpidium, a cycad reproductive structure known only from the Late Triassic of Bavaria and its possible leaves, cf. Ctenophyllum, also known only from the early Mesozoic; cf. Swedenborgia, a voltzialean conifer reproductive structure typical of the Late Triassic and Early Jurassic; Ullmannia, conifer foliage found both in the Late Permian and Triassic; seeds of cf. Agathis, an extant conifer first known from the Early Cretaceous. More typically Paleozoic taxa include Wattia, Taeniopteris, and cordaites. This flora is overwhelmingly dominated by seed plants typical of xeric habitats. Its "precocious" nature indicates that many of the dominant plant groups of the early Mesozoic had evolved, probably in well drained uplands, by the Early Permian. They survived the supposed devastation of the late Permian extinction due to their tolerance of more physiologically demanding habitats. The absence of these plants from most of the Paleozoic record is likely a taphonomic happenstance; areas of moisture stress, such as those to which these plants are adapted, are generally distant from depositional basins. Gypsum-laden deposits are rarely searched for plant fossils, perhaps explaining the discovery of this flora only recently.

In terrestrial floras high rates are characteristic of the Pleistocene-Holocene, but low rates generally have been recorded in studies of the deep past. Discussions of rates of compositional change have rarely considered the effect of the temporal separation between samples on apparent rates. For this study I downloaded 12 palynological data sets from the NOAA Paleoclimatology Program online database (http://www. ngdc. noaa. gov/paleo/ftp-pollen. html). I chose sites with records longer than 30 k.y., and that spanned latitudes from 68 degrees N to 17 degrees S. Each data set consisted of a samples by species matrix, with cells values recording the number of grains of each taxon in each sample. Age models from the original investigators were accepted for this study; for most cores age models were derived by interpolating between radiocarbon dates based on stratigraphic level. Aquatic taxa and indeterminate pollen types were deleted from the data sets prior to analysis; terrestrial taxa were converted to percent abundance data, and chord distances were calculated between all pairs of samples. Temporal differences were also calculated for all pairs of samples. The rate of floral change was expressed as the chord distance between two samples divided by the time difference. All of the data sets examined showed a strongly log-linear relationship between the temporal separation of two samples and the apparent rate of floral change between them. Slopes of the relationship on a log/log plot varied between -0.77 and -0.95 (reduced major axis regression), and r-squared values were 0.77-0.91. As with other highly episodic or reversible processes, such as evolution and sedimentation, rates of change of floral composition are not true rates, and must be scaled for the duration of measurement before they can be compared.

Issyk-Kul is highly oligotrophic (max. Secchi depth 47 m), slightly brackish (6 per mil) and alkaline, with carbonate-rich sediments and a long history of large-scale (10's-100's meters) and ongoing lake-level change. A combined program of piston-coring and direct sampling of drowned, living, and perched littoral features (calcareous microbialites and inorganic beachrock pavements) aims to reconstruct Late Pleistocene-Holocene fluctuations of lake level, hydrography, and paleoclimate in this arid and remote continental region. Five piston cores up to 4.3 m in length were recovered from waters between 230 and 631 m deep, and selected for detailed analyses of constituents, grain size, carbonate content, mineralogy, and stable isotopes ( (super 13) C/ (super 18) O) of carbonates. While AMS radiocarbon-dates of larger ostracodes are expected prior to the GSA meeting in Toronto, previous estimates of slow pelagic sedimentation (0.1-0.2 mm/yr) suggest a record of ca. 20-40 kyr in our cores. Core profiles are dominated by light to very dark gray, homogeneous or laminated, fine-grained (typically more than 94% <38 microns) sediments, which are rich in calcite (range 14-54%) of endogenic (monohydrocalcite; CaCO (sub 3) .H (sub 2) O) and ostracode origin. Preserved organic carbon (generally <1%) and biogenic silica are rare. Turbidites are common across the basin, appearing as mm-decimeter-scale coarse units rich in displaced shelf materials (e. g. , granitic sands, Fe-sulfide-stained ostracodes, plant debris, diatoms). Textural, constituent, and mineralogical anomalies in non-turbidite units appear related to episodes of sucrosic calcite precipitation, as well as the early diagenetic formation of Fe-sulfides. Two long cores from the western side of the basin appear to have correlatable profiles of CaCO (sub 3) , and are currently being analyzed for paleoclimatic signals.

We believe nearly all these Cretaceous taxa were reworked from older Cretaceous sediments for four reasons: 1) large individual foraminifera typical of the Cretaceous do not record a dramatic cooling event seen in oxygen isotope records of Paleocene planktic foraminifera and fine-fraction carbonate. Instead, the Cretaceous species have both oxygen and carbon isotope ratios similar to their conspecifics in the late Maastrichtian. 2) Typical Cretaceous taxa found in Paleocene sediments and in the ejecta bed are size-sorted; there is a curious absence of small specimens unlike the size distribution present in upper Maastrichtian foraminifer assemblages. 3) In contrast, species known to be indigenous to the Paleocene are uniformly minute. 4) Large specimens of foraminifera typical of the Cretaceous are almost always filled with matrix unlike the enclosing Paleocene ooze and contain nannofossil taxa that became extinct well before the close of the Cretaceous. Apparently most of the larger specimens of typical Cretaceous taxa did not survive the boundary. If only the small specimens are genuine survivors, then the K-T extinction must have been extremely severe with no more than three species of planktic foraminifera surviving the boundary event in the western Atlantic.

In contrast, bivalves from the same beds are related to craton-bound Northern Hemisphere taxa and suggest an older (late Anisian or early Ladinian) age.The bivalves are mainly byssate or cemented forms that lived in close association with the corals. The craton-bound indicators are a new genus and species of pectinid and a mysidiellid congeneric with but more primitive than taxa in the Carnian of NE British Columbia. Late Anisian age indicators are the first definite Pleuronectites to be found in North America, which resembles Anisian Pleuronectites laevigatus in the Lower Muschelkalk of Europe, and a fragment of a small pectinoid that resembles Antijanira amphidoxa from the Anisian of Yugoslavia. An early Ladinian age is suggested by a fragment of a large plicatulid that resembles a Pseudoplacunopsis from the lower Ladinian of Israel. A late Anisian or early Ladinian age for this assemblage is within the constraints imposed by uppermost Ladinian (Sutherlandi Zone) ammonoids that occur well above these beds and by late Anisian (Meeki Zone) ammonoids and Daonella occurring below the coral beds. The contrasting biogeographic and age indications of different components of this coral-associated assemblage may result primarily from differences in evolutionary rates in a setting that was near the northern limit of development for early colonial corals. The corals and forams were slowly evolving; more rapidly evolving bivalves dispersed southward to the coral zone and became adapted to life among the corals. Regardless of age, this Middle Triassic cratonal fauna provides a new taxonomic data set that may prove useful for assessing the timing and magnitude of displacement of allochthonous terranes.

Furthermore, identification of such marine influence has bearing on interpretation of the habitats of early land plants (embryophytes) preserved in these strata. Throughout the Cap-aux-Os Member, acritarchs (organic-walled microfossils of algal origin) are pervasive in strata interpreted as marine in origin based on macrofossils (e.g. brachiopods) and trace fossils. However, the occurrence of acritarchs in discrete intervals within floodplain shales that lack other marine fossils indicates marine incursions that might otherwise be undetected. Similarly, trace fossils of the Skolithos ichnofacies suggest a coastal-nearshore setting for some strata that otherwise lack clear evidence of marine influence. Some autochthonous plant-fossil assemblages in the Cap-aux-Os Member occur within the upper parts of meters-thick sandstone bodies that are interpreted as the deposits of tide-influenced channels from a position very close to the tidal limit. The plants became established in the muds deposited within ephemeral channels crossing bar tops, and on levees, following periods of high water (due to floods or exceptionally high tides). The plant axes became reoriented and buried with sediment during subsequent high-water periods. These plant-bearing strata do not contain acritarchs or other marine fossils and trace fossils, although immediately adjacent strata do. Thus, although the plants may have tolerated occasional incursions of brackish water, due to their close proximity to the shoreline, they lived in freshwater habitats and were certainly not subjected to fully marine conditions during life.

This unique event, which occurred suddenly 13000 years ago, begs a unique or unusual cause. First contact between New World faunas and significant numbers of modern human predators, which occurred at this time, is one possibility. Yet the scarcity of butcher sites and skepticism about the importance and efficiency of human hunting raise serious doubts about this mechanism for extinction. Alternatively, the extinction has been attributed to a rapid climate change, which triggered a floral reorganization that disrupted herbivore feeding patterns. Through analysis of oxygen isotope and pollen records, we explore three issues raised by the environmental hypothesis. Were the rate and magnitude of climate change at the end Pleistocene unusual in comparison to prior transitions? Were rates of floral change uniquely high at this time in comparison to earlier events? Was the flora of the earliest Holocene unusual when compared to floras from earlier warm intervals? The first question has an unambiguous answer. Rates and magnitudes of climate change at the end Pleistocene were high, but not significantly higher than at prior cool-to-warm climate transitions. Analysis of rates of floral change provides a mixed answer. The highest rates of floral change in the past 50000 years typically occur between 15000 and 9000 years ago, yet pollen records through previous glacial/interglacial cycles are rare, and the maximum rates of floral change do not always precisely coincide with the mammalian extinction. The final question is unresolved. Holocene floras at some sites resemble interstadial floras in species composition, but we have few comparisons and little information on other aspects of vegetation that may be important to herbivores. Overall, while it seems unlikely that the rapidity of environmental change at the end Pleistocene confronted large mammals with a unique challenge, we can not presently preclude the possibility that the structure or composition of early Holocene vegetation played a role in the extinction.

As inferences move from pattern to process, ancillary data of taxonomic, environmental, or functional nature have been utilized. However, developmental data are much less frequently considered in morphospace studies, and yet intrinsic ontogenetic biases stand as one major framework of explanation. The notions of developmental disparity and developmental morphospaces (defined by incorporation of developmental data) are here illustrated as a means of approaching issues such as clade shape in ontogenetic time, general changes in rate and timing, testing of developmental "laws", and links between phylogenetic and ontogenetic trends. Echinoids of the order Spatangoida are used as a case study. Adults and post-metamorphic juveniles across the order are described by means of a landmark-based morphometric analysis. Disparity between pooled adults and pooled juveniles is compared, and also interpreted in a phylogenetic framework. The distributions of resampled total juvenile and adult disparities are indistinguishable, but there is much dissociation of growth trajectories in morphospace, with many instances of taxonomically heterogeneous juvenile/adult clusters. Instances of clustering of juveniles from different taxa also occur, thus partially supporting Von Baer's second law (VBSL, which states that more specific morphologies are developed from more general ones). Different composite variables, however, suggest no consistent support for VBSL, with cases of similar disparity in juveniles and adults (contra VBSL), of higher disparity in adults (pro VBSL), and of higher disparity in juveniles (contra VBSL). When developmental disparity is mapped on a phylogeny, lack of support for VBSL is again implied: juvenile/adult disparity contrasts based on clade ranks indicate that within subclades juveniles tend to be more variable than adults; there is also no phylogenetic/stratigraphic trend toward greater disparity of ontogenetic endpoints. There is thus no single vector of change in disparity through ontogeny. Still, all such developmental action potentially driving evolution occurs within a constrained morphospace which is similarly partitioned in ontogenetic and evolutionary time. These results are in disagreement with what can be inferred from vertebrate model systems; their generality should be further explored with analyses of developmental disparity in other invertebrate groups.

We present the first geological map and formal physical stratigraphy for the Neogene sediments of Darien. The new stratigraphic units, from base to top, are the Clarita, Tapaliza, Tuira and Chucunaque formations. The Neogene chronology and environmental history are described using planktonic and benthic foraminifera and calcareous nannoplankton from sections of the Chucunaque-Tuira and (to the southwest) Sambu river basins. Middle Miocene, cosmopolitan benthic foraminifera from the Clarita and Tapaliza formations (Chucunaque-Tuira basin) and coeval (early middle Miocene), unnamed Sambu beds indicate normal, well oxygenated, middle to upper bathyal waters. An unnamed, upper middle Miocene formation overlying the Tapaliza Formation contains a mixture of cosmopolitan and typical Pacific low-oxygen, upper bathyal benthic foraminifera. The late Miocene (nannoplankton Zone NN9, planktonic foraminiferal Zone N16) Tuira Formation of the Chucunaque-Tuira basin contains an outer neritic, low-oxygen facies with typical Pacific benthic foraminifera to the south, while to the north it is younger (N17), shallower (inner-middle neritic), and normal marine. Upper Miocene (NN11, N16 and 17) benthic foraminifera of the Chucunaque Formation (Chucunaque-Tuira basin) and unnamed beds of the Sambu basin are typical Pacific species indicative of low-oxygen, outer neritic to upper bathyal waters. In summary, Darien waters shallowed from middle bathyal to outer neritic depths from 16.4-15.6 Ma to 8.3-5.6 Ma. Benthic foraminifera were mostly cosmopolitan until about 12 Ma, when a typical eastern Pacific, low-oxygen biofacies was apparently established at upper bathyal depths, which suggests a cutoff from Caribbean circulation at upper bathyal and greater depths.

One of these specimens was illustrated by Johann Jakob Scheuchzer as early as 1709 but was not described. The new taxon has a unique combination of derived characteristics that relate it to the zeiform+tetraodontiform and, perhaps, caproid clades of acanthopterygians, probably near to one of the branchings of the zeiform+tetraodontiform, beryciform, and lower percomorph clades from one another.

The upper part of the Aksyir svita produces mammals, including abundant rodents, that typically occur in the Ergilin-Dzo fauna of Mongolia and its correlates in Mongolia and China; it is thus considered Ergilian. Above the Aksyir is the Kusto svita, which is conformably overlain by the Buran svita; the latter two units are not everywhere separable on lithologic criteria. The Ergilian-Shandgolian transition is within this Kusto-Buran interval. Cadurcodon ardynensis occurs in this Kusto-Buran unit and in both Ergilian and Shandgolian deposits of Mongolia and China. Two quarry samples from the lower and middle parts of the Kusto-Buran unit have cylindrodont, zapodid, and cricetid rodents that are distinctly more derived than those from the upper Aksyir, but less derived than those from Shand Gol, Mongolia. A large quarry sample from a slightly younger level, clearly within the Buran "svita," has zapodids that are even more derived, along with the first occurrences of typical Shandgolian rodents: Cricetops, Eucricetodon asiaticus, Aplodontidae (Prosciurus), Tsaganomys (and/or includes Cyclomylus), castorids, and Tataromys.

The lower sequence rests disconformably on bentonitic marine shale of the upper Eocene-lower Oligocene Chegan Formation and consists of the Kutanbulak Formation, as much as 28 m of fine-grained quartzarenite, overlain conformably by the Chilikta Formation, as much as 23 m of shale and thinly interbedded shale/sandstone. The younger sequence begins with the Chagray Formation, as much as 33 m of micaceous sandstone that disconformably overlies the Chilikta. The Chagray grades upward into the Aral Formation, >24 m of calcareous shale and claystone. Stratigraphy, facies architecture, and paleontology support interpretation of the Kutanbulak and Chagray as lowstand and/or early transgressive systems tracts composed of river and delta deposits that infilled incised topography that previously developed during lowstand. Chilikta and Aral strata are late transgressive systems tracts and highstand systems tracts--mostly deposits of estuaries and lakes. Homotaxis to marine strata on the Ustyurt Plateau and marine bivalves indicate the Chilikta is late Rupelian, and the Chagray is Chattian. The oldest Oligocene fossil mammals in these strata occur in the lower Chilikta--fragmentary remains of sirenians and of the giant rhinoceros Paraceratherium. This is the oldest local record of Paraceratherium and its only direct tie to marine biochronology. The classic mammal assemblage collected near Agyspe comes from the Aral Formation, as do recently collected micromammal assemblages from Altyn Chokysu and vicinity. Some Russian workers now regard these assemblages as of early Miocene age, but we identify them as late Oligocene because: 1) the Aral Formation is part of the same sequence as the Chattian Chagray Formation; 2) most of the genera and many of the species of Aral insectivores, lagomorphs, and rodents are known from the late Oligocene Tabenbulukian faunas of China and Mongolia: and 3) Aral megamammals include genera such as Lophiomeryx, Prodremotherium, Protaceratherium, Aprotodon, and Paraceratherium found in the European and/or Chinese late Oligocene. The Aral Formation fossil mammal assemblage represents one of the best documented late Oligocene mammal faunas known from Asia.

Between depths of 300-700 m the cone has slopes of 21 degrees resulting from angle-of-repose deposition of submarine pyroclastic gravity flows. Some flows were generated by explosions and dome collapse; others were triggered by remobilization of upslope debris. Tephra dispersed 1-2 km from the summit in repeated subaerial eruption columns fell into sea-water up to 400 m deep. In the passage from air into sea the upper part of the water column was repeatedly choked with hyperconcentrations of tephra from which vertical density currents descended the submarine slopes of the volcano. Fine tephra elutriated by upwelling plumes of heated sea-water were carried by ocean currents to distal areas to form a component of deep-sea sediment.

All previous studies indicated that relative sea level was higher from approximately 7500-4000 yrs. BP, then lowered and stabilized at about present msl during the past 3000 yrs. To the contrary, we find that sea level has been rising relative to the southern Yangtze delta plain based on new sea-level data derived from dated peats, reassessment of earlier sea-level curves and measurement of delta plain subsidence and analysis of prehistoric habitat bases from approximately 7000 to 3000 yrs. BP. Consequences of this relative rise include difficulty in expelling water from the low-lying delta plain to the coast and associated flood damage. Emplacement of the 3-Gorges Dam on the Yangtze will control flooding of the Yangtze river but decrease sediment accumulation on the delta plain that, in turn, is likely to accelerate saline inundation of this vital breadbasket.

During the past 7000 years world deltas, including the Nile, have been in an overall construction phase. However, the Nile delta has converted to a destruction phase during the past 150 years, triggered by water regulation which has disrupted the balance among sediment influx, erosive effects of coastal processes, and subsidence. This former depocenter has been altered to the extent that it is no longer a functioning delta but, rather, a subsiding and eroding coastal plain. Symptoms of the destruction phase of the Nile delta include accelerated coastal erosion and straightening of the shoreline, reduction in wetland size, increased landward incursion of saline groundwater, and buildup of salt and pollutants to toxic levels in wetlands and delta plain. Without seasonal flushing by floods, the former delta plain surface is now incapable of recycling and/or removing agricultural, municipal and industrial wastes generated by Egypt's rapidly expanding population. Moreover, the remaining capacity of the system to regenerate itself will further diminish as water is diverted away from the delta for new irrigation and municipal projects in the Egyptian desert, and water allocations to Egypt are decreased by upstream countries. Reestablishing some level of natural hydrology is the only credible solution for attaining equilibrium among sediment accretion on the delta plain to offset subsidence, progradation along the coast to offset erosion, and sufficient water influx to flush and remove the high levels of salt and pollutants throughout the system. However, increased Nile water and sediment discharge could begin to restore a functioning delta system only if there is a substantial reduction in human impacts.

The first change in composition resulted largely from an extended period of extinction, the second was the result of a period of accelerated immigration of plants into the Bighorn Basin. The extinction interval spanned the latest Paleocene carbon isotope excursion, but lasted much longer, extending through the middle and later part of Chron C24r (1.0-1.5 my). The extinction began during a period of rising temperature in the later Clarkforkian Age, but continued into the earliest Wasatchian Age, for which time physiognomic and isotopic evidence indicates declining temperatures. The succeeding immigration interval occurred during a period of approximately 0.5 my near the beginning of Chron C24n, and is associated with physiognomic, floristic, and isotopic evidence for climatic warming in the Bighorn Basin. The immigration roughly corresponds to the Cenozoic temperature maximum seen in marine isotopic records. During the early Eocene Period trends in plant richness correlated roughly with changes in temperature. Richness and temperature declined in the earliest Wasatchian Age (although the minimum of richness may be earlier than the minimum of temperature), and then increased in the early to middle Wasatchian Age. For the latest Paleocene Epoch there is less correlation between plant richness and estimated temperature. Estimated richness is either flat or declining through the Clarkforkian NALMA, once sample size has been controlled for, but there is good evidence for rising temperature. It remains to be explained why richness declined during the late Paleocene warming but increased during the mid-early Eocene warming. Periods of floral and mammalian faunal turnover are not strongly coincident through the late Paleocene-early Eocene interval, but there are three periods that suggest some concordance: an early Clarkforkian increase in immigration, a late Clarkforkian decrease in immigration, and a middle Wasatchian period of high immigration. Conspicuously absent is any floral event equivalent to the earliest Wasatchian immigration in mammals. Global warming and intercontinental migration have been implicated as major influences on the timing and magnitude of terrestrial biotic change in the late Paleocene and early Eocene Epochs. The paleoclimatic estimates presented here suggest that there was more than one episode of warming near the Paleocene/Eocene Epoch boundary, and that the long, cool interval in between the warmest periods was also an important determinant of composition, turnover rates, and richness in the flora. If the climatic fluctuations recorded in the Bighorn Basin affected the northern mid- to high latitudes generally, then it may be that biotic exchange between the Holarctic continents via high-latitude land-bridges took place as a series of pulsed events, rather than in one long, warm period. Resolving these pulses will require continued refinement of the North American record, but also the development of similar fine-scale records on other continents.

The data, taken mainly from the literature on comparative morphology, corroborate the notion that bivalves were derived from primitive, Early Cambrian rostroconchs but not the idea that scaphopods are more closely related to bivalves than to gastropods or cephalopods. The latter two classes plus scaphopods are united by several unique, derived characters, including an epipodium and the freedom of the head from attachments to the shell. Head freedom was enhanced in gastropods by the innovation of torsion and in the Scaphopoda plus Cephalopoda by the innovation of endogastry. Within the Bivalvia, the subclass Protobranchia evolved specialized structures for deposit feeding via palp appendages; the Autobranchia evolved structures that enhanced suspension feeding via the gills. Within the Autobranchia, a basal dichotomy separates the Pteriomorphia from the Heteroconchia, the latter comprising the Palaeoheterodonta, Heterodonta, and Anomalodesmata. Only the Pteriomorphia is analyzed in detail here, with discussions addressing the origin of anisomyarianism, inequivalvedness, the monophyly of oysters, and the origins of scallops. The evolution of hinge teeth, ligament systems, and the position and shell insertion of the anterior adductor suggest that the Early Ordovician roots of the Autobranchia lie in ancestors that had taxodont hinge teeth but lacked the specializations now associated with the Protobranchia.

Vascular plant and insect associations are essentialy modern during this interval, and consist of external foliage feeding, leaf mining, galling, wood boring, piercing-and-sucking, sporivory and pollinivory, nectarivory, and pollination syndromes. Late Jurassic versions of all these interactions occurred on a diverse repertoire of major gymnospermous plant clades (angiosperms excepted) whereas by the end of the Middle Cretaceous most of these interactions had been transferred onto angiosperms either by descent from gymnospermous ancestors or by direct host transfer. Examples of these host-plant shifts include generalized external foliage feeding, probable host-specific leaf mining, galling, pollinivory, and nectarivory. While most of these associations did not persist to the present, there is evidence that relict, primitive insect lineages survived as intimate herbivores today on host-plant taxa with Late Jurassic to Middle Cretaceous ancestors, notably cycads and primitive dicotyledonous angiosperms.

In contrast, our study of living specimens of a common species of this group, Archaias angulatis, indicates a sequence in which textural alteration of the magnesium calcite skeleton occurs without loss of magnesium from the test. In samples of A. angulatis from Florida Bay, Florida, skeletal rods (1-2 micrometers long and 0.1 micrometers wide) are extensively recrystallized to dense minimicrite (0.05- 0.1 micrometers anhedral equant crystals). Both rods and minimicrite contain 9-11.5 mole % MgCO (sub 3) . Micritization increases with age of the skeletons and occurs more rapidly in septal and basal walls than in lateral walls and pillars. Recrystallization could be due to change in the partial pressure of CO (sub 2) resulting from changing distributional patterns of respiration and photosynthesis of algal symbionts. Recrystallization within living foraminifera has important implications for studies of fossil diagenesis and biomineralization.

Mapping was carried out on published 1:2M photobases of MC-15SE, 15SW, 23NE, and 23NW (15 degrees S to 15 degrees latitude, 180 degrees to 225 degrees W longitude) which include the westernmost exposures of MFF. Mapping was based on existing Viking images, although new Mars Global Surveyor (MGS) data from MOLA, MOC, and TES hold great potential for adding significantly to the Viking-era data. We have identified seven subunits in the lowest member of MFF, which compliment the three subunits identified previously in each of the middle and upper members exposed in the eastern portion of MFF. All MFF materials are superposed on top of other Martian material units found in their vicinity. When compared with recently released MOLA topographic data, the new subunits of the lower member of MFF appear more topographically consistent than did previous globally mapped units. Erosion by release of volatiles (or volatile-rich sediment flows) from the heavily cratered highlands south of MFF played an important role in the shaping of deposits exposed in western MFF, supplemented by the aeolian erosion evident throughout all of MFF. The new mapping should provide an improved basis with which to evaluate future MGS data as they become available. This work was supported by NASA grant NAG5-4586 (JRZ) and the PGGUR Program (BMH).

I examined whether and how fluctuating light supply affects the structure and dynamics of phytoplankton communities. The effect of light fluctuations was tested at two average irradiances: low, 25 mu mol quanta m super(-2) s super(-1) and high, 100 mu mol quanta m super(-2) s super(-1) in 2- and 18-species communities of freshwater phytoplankton. Species diversity, and abundances of individual species and higher taxa, depended significantly on both the absolute level and the degree of variability in light supply, while total density, total biomass, and species richness responded only to light level. In the two-species assemblage, fluctuations increased diversity at both low and high average irradiances and in the multispecies community fluctuations increased diversity at high irradiance but decreased diversity at low average irradiance. Species richness was higher under low average irradiance and was not affected by the presence or absence of fluctuations. Diatom abundance was increased by fluctuations, especially at low average irradiance, where they became the dominant group, while cyanobacteria and green algae dominated low constant light and all high light treatments. Within each taxonomic group, however, there was no uniform pattern in species responses to light fluctuations: both the magnitude and direction of response were species-specific. The temporal regime of light supply had a significant effect on the growth rates of individual species grown in monocultures. Species responses to the regime of light supply in monocultures qualitatively agreed with their abundances in the community experiments. The results indicate that the temporal regime of light supply may influence structure of phytoplankton communities by differentially affecting growth rates and mediating species competition.

The ultimate effects on the female reproductive success of flowers, such as fruit set, seed predation rate, and final seed set were also measured. We applied three levels of petal removal (100%, 50%, and 0% size reduction in radius) to flowers in natural populations. Two pollinators (Bombus pennsylvanicus and Ptilothrix bombiformis) ignored flowers without petals, suggesting that pollinators use petals as a visual cue to locate flowers. Consequently, 100% petal removal reduced female reproductive success considerably, mainly through a higher rate of fruit abortion due to failure of pollen deposition on stigmas. No significant differences between the 50% petal removal treatment and uncut control were detected in any components of female success examined. The results, therefore, suggest that differences in petal size have little influence on female reproductive success of Hibiscus flowers at our study site. Final seed set varied considerably depending on the larval densities of two coleopteran seed predators (Althaeus hibisci and Conotrachelus fissunguis). A. hibisci responded to petal size, and a higher density of adults was found in flowers in which petal size had not been reduced. Because Althaeus feed on pollen as adults and no effect of petal size on seed predation was detected, the preference of Althaeus for larger flowers may represent a foraging strategy for adult beetles and may exert counteracting selection pressure on petal size through male reproductive success of flowers.

Of the 472 1 x 1 degree grid cells in Amazonia, only nine cells are included in the highest species diversity category (43-67 total species) and nine in the highest endemic species diversity category (4-13 endemic species). Over one quarter of the grid cells have no museum records of any of the organisms in our study. Little correspondence exists between the centers of species diversity identified by our collections-based data and those areas recommended for conservation in an earlier qualitative study of Amazonian biodiversity. Museum collections can play a vital role in identifying species-rich areas for potential conservation in Amazonia, but a concerted and structured effort to increase the number and distribution of collections is needed to take maximum advantage of the information they contain.

At an intertidal sand bar in the Pacific entrance of the Panama Canal, worms ate about 0.1% of the adult crab population per day. The mode of attack and the spatial and temporal distributions of interactions suggest the worm is an ambush predator. When struck by a worm's sticky, mucous-covered proboscis, crabs produced copious foam from their buccal area. Mucous-laden crabs that escaped, again foamed indicating that the foam may counteract the mucus. If the attack led to a kill, the struggling crab soon became quiescent, as is typical in other nemertean-prey interactions. The worm inverted its proboscis, found ingress to the crab's body and fed. Crabs escaped by autotomizing appendages entwined by the proboscis, by forcefully pulling away and by remaining quiescent, then moving away when the worm inverted its proboscis and before it entered the crab. Immobility, a response to visual predators, may falsely indicate paralysis to the worm and cause it to invert its proboscis, thereby providing the crab with an opportunity to escape. This predator-prey interaction seems to incorporate generalized predator tactics and fortuitous prey defenses that give worms and crabs about an even chance of success.

We used both methods on the same 30 sites in southern Veracruz: 10 sites in forest (canopy >10 m), 10 sites in second growth (canopy 3-10 m), and 10 sites in the open (canopy <3 m). Results demonstrate that either method used alone is likely to underestimate or miss whole categories of species. Three aerial or canopy-foraging species found on point counts were missed by mist netting, while several others in these categories were under-represented in mist net samples, especially in forest habitats. Nine species represented in mist net samples were not recorded in point counts, probably because of low density and/or secretive habits. The strengths of one method tend to offset the weaknesses of the other, and we propose a methodology that combines both procedures to provide a more accurate assessment of avian habitat use.

Communities grew from 20 cm to approximately 2 m in height in 6 months. No enhancements in plant biomass accumulation occurred under elevated CO sub(2) either in the whole communities or in growth of individual species. Reductions in leaf area index under elevated CO sub(2) were observed, as were decreases in leaf nitrogen concentrations and increases in the C:N ratio of leaf tissue. Species tended to respond individualistically to elevated CO sub(2), but some generalizations of how successional groupings responded could be made. Early and mid-successional species generally showed greater responses to elevated CO sub(2) than late-successional species, particularly with respect to increases in photosynthetic rates and leaf starch concentrations, and reductions in leaf area ratio. Late-successional species showed greater increases in C:N ratios in response to elevated CO sub(2) than did other species. Our results indicate that there may not be an increase in the growth of regenerating tropical forest under elevated CO sub(2), but that there could be changes in soil nutrient availability because of reductions in leaf tissue quality, particularly in late-successional species.

The aim was to assess the importance of dispersal limitation (failure of seeds to arrive at all sites suitable for their germination) and establishment limitation (failure of seeds having reached a site to germinate successfully and establish as seedlings) in determining patterns of gap occupancy. The abundance of seeds in the soil seed bank was strongly negatively correlated with seed size, but was not correlated with the abundance of reproductive-sized adult trees in the plot. In contrast, the abundance of pioneer seedlings > 10 cm height in natural gaps was strongly correlated with adult abundance, but was not correlated with seed size. Seedlings were non-randomly distributed among gaps, but seedling abundance was not directly related to gap size, and there was no evidence of partitioning of the light environment of gaps by small seedlings. Large differences in growth and mortality rates among species were observed after 1 year, and this may result in the gap size partitioning previously found in saplings of the same species. Seedlings of most species, particularly those with large seeds, were relatively more abundant than expected in gaps close to their conspecific adults. Proximity to reproductives, and by inference dispersal limitation, therefore exerts some effect on seedling distribution. None the less, large differences between seed and seedling abundances for some species, and low seedling occupancy rates in some gaps close to adult conspecifics, suggest that seedling emergence probabilities and species-specific establishment requirements may also be important determinants of local abundance.

The contributions cover the general systematics and biogeography of the majority of the ecologically, economically, and biomedically important families of cephalopods. The work begins with a series of contributions on the analysis of systematic characters, a necessary activity in the study of the systematics of any group. This is followed by the largest section, consisting of the systematic and biogeographic treatments of seven cephalopod families: Sepiidae, Loliginidae, Enoploteuthidae, Onychoteuthidae, Histioteuthidae, Ommastrephidae, and Octopodidae. These families were chosen for study based on a combination of their relative importance and the need for improved systematic knowledge. The work concludes with a summary of the current classification, type localities, and type repositories of the Recent Cephalopoda. The workshop organizers intend these volumes to serve as a companion to Smithsonian Contributions to Zoology, number 513, 1992.

The Pandanus species had similar maximum photosynthetic rates (A sub(max)) to dicotyledon tree species in leaves from both sun and shaded environments when A sub(max) was expressed on an area basis. Because of the low specific leaf area of the schlerophyllous leaves of the Pandanus compared to the dicotyledon species, the similarity in A sub(max) was no longer evident when A sub(max) was expressed on a dry-weight basis. Leaf dark respiration rates of the Pandanus on a leaf area and weight basis were generally lower than the shade-intolerant dicotyledons and similar to the shade-tolerant dicotyledon species. Low dark respiration rates and low specific leaf area of the Pandanus may be important characteristics for growth and survival in environments where resource levels are low and the likelihood of tissue damage is high.

Swainson's Warbler is a terrestrial dead-leaf specialist and "leaf-lifting" was the principal search/attack maneuver of all observed individuals. Pattering or vibration of feet is an important but previously unrecognized behavior associated with foraging in leaf litter. Observations indicate that leaf litter is a critical component of Swainson's Warbler habitat on breeding and winter territories and at migratory stopovers.

Offshore margin between Nile Delta and northern Israel AN - 16432964; 4337198 AB - Clay assemblages in Holocene sediment on southeast Mediterranean margins are generally smectite-rich and, in the past, were derived primarily from direct River Nile input to the sea. Depositional patterns in the Nile littoral cell are now undergoing extensive change, largely as a response to closure of the High Dam at Aswan (1964), increased sediment entrapment by canal systems in the Nile delta, and construction of large coastal structures between the Nile delta and Israeli margins. Although information on land-to-sea dispersal by the River Nile and other fluvial and offshore sediment sources to the east remains limited, there appears to be evidence for increased sediment input from erosion of Sinai and Levant shelves and coasts east of the Nile delta. This, the third in a 3-part study that focuses on regional clay mineral distributions, was initiated to provide baselines to measure evolving changes of sediment provenance and dispersal patterns on the shelves and upper Nile Cone between the Nile delta and northern Israel. The investigation shows that clay assemblages are not uniformly distributed in the SE Mediterranean, likely a result of several important sediment sources in addition to the Nile.

In this study, I used a four-choice chamber apparatus to investigate this preference, and to determine whether it is influenced by band coloration. I created band combinations by banding males with four leg bands. The symmetrical combinations consisted of two bands on each leg; the asymmetrical combinations consisted of three bands on one leg and one band on the other leg. For each of the symmetry treatments, all four bands were either light green or red. Females did not spend significantly more time associating with males wearing symmetrical bands or with males wearing red bands. The duration of male-female associations was not influenced by an interaction between symmetry category and band colour treatment. None of 10 females spent the most time with males with red symmetrical bands. JF - Animal Behaviour AU - Jennions, MD AD - Smithsonian Trop. Res.

In response, the Malaysian Wildlife Department has translocated over 392 elephants from plantations into protected areas since 1974. Dense rain forest and steep terrain at the release sites have made it near impossible to follow the movements of the released elephants and evaluate the success of the programme. In October 1995, a translocated female elephant was fitted with a satellite transmitter to determine its post-release movements. By August 1996, the female had moved within a range of 7000 sq km. The movements were erratic initially and covered a large area. They were followed by a shift in location twice, each time covering successively smaller areas. Attempts to locate and follow the female on the ground revealed no evidence that she travelled in a group. A second, male, elephant was equipped with a satellite transmitter in February 1996 and by August 1996, it had moved within a range of 350 sq km. An attempt to locate and follow the male on the ground provided evidence that he was in a group of at least three individuals. The difference in the behaviour of the two elephants, released at exactly the same location, is striking, but additional elephants need to be followed to increase sample size and allow a scientific explanation of the findings.

Phosphorus tends to be retained efficiently in these aquatic systems. The Redfield ratio concept is based on the fact that algae, under reasonably good growth conditions, will have an elemental composition with relatively defined atomic ratios. For nitrogen:phosphorus, this ratio is approximately 15 to 16:1. When receiving waters have limiting amounts of phosphorus the phytoplankton biomass has nitrogen:phosphorus atomic ratios significantly above the Redfield ratio. When nitrogen is limiting, the Redfield ratio is much lower. Acceptable concentrations of phosphorus are discussed. There are 62 references.

Turbidity and Kd measurements were taken along 3 transects from April to October in 1993 and 1994. Turbidity and Kd were significantly increased for in-plume samples compared with out-of-plume samples. Higher values were recorded at water depths of 1 m than at deeper depths. Near-shore waters had higher turbidity and Kd values than mid-channel waters. Nine sediment plumes were tracked with drogues. It took an average of 2.9 h and 4.8 h for the turbidity and Kd, respectively, to return to 95 per cent of background values after dredging ended. The Eulerian time-series obtained from monitoring in a stationary location showed exponential decay for both turbidity and Kd. Clam boats and sediment plumes were examined with a geographical information system (ARCO/INFO) to provide estimates of the areal extent of sediment plumes from clam dredging.

The SO (sub 3) contents of the experimental apatite increase with increasing oxygen fugacity (f (sub O2) ), from < or =0.04 wt% in reduced charges buffered by fayalite-magnetite-quartz (FMQ), to 1.0-2.6 wt% in oxidized charges buffered by manganosite-hausmanite (MNH) or magnetite-hematite (MTH). The SO (sub 3) contents of MNH- and MTH-buffered apatite also generally increase with increasing pressure from 2 to 4 kbar and decreasing temperature from 950 to 800 degrees C. The partition coefficient for SO (sub 3) between apatite and oxidized melt increases with decreasing temperature but appears to be independent of pressure. Apatites in volcanic rocks show a wide range of SO (sub 3) contents (< or =0.04 to 0.63 wt%). Our sample set includes one group known to contain primary anhydrite and a second group inferred to have been free of primary anhydrite. No systematic differences in apatite S contents are observed between these two groups. Our study was initiated to define the factors controlling S contents in apatite and to evaluate the hypothesis that high S contents in apatite could be characteristic of S-rich anhydrite-bearing magmas such as those erupted from El Chichon in 1982 and Pinatubo in 1991. This hypothesis is shown to be invalid, probably chiefly a consequence of the slow intra-crystalline diffusion that limits re-equilibration between early formed apatite and the evolving silicate melt. Contributing factors include early crystallization of most apatite over a relatively small temperature interval, common late-stage magmatic enrichment of S. progressive oxidation during magmatic evolution, and strong controls on S contents in apatite exerted by f (sub O2) , temperature, and pressure.

Leaf fossils were assigned to morphotypes and their physiognomy was quantified for palaeoclimatic analysis. Two methods were used, Climate Leaf Analysis Multi variate Program (CLAMP) and Leaf Margin Analysis (LMA). Temperature estimates and trends derived from CLAMP and LMA indicate that early Palaeocene palaeotemperatures decreased from the latest Cretaceous, particularly in northern areas of North America. Climatic zones shifted southwards from their latest Cretaceous positions, resulting in a steepened north-south temperature gradient and decreased equability in the early Palaeocene. Sub-tropical conditions prevailed as far north as the Raton Basin with the 20 degrees C mean annual temperature isotherm (megathermal-mesothermal boundary) located at approximately 45 degrees N palaeolatitude. The 13 degrees C mean annual temperature isotherm (mesothermal-microthermal boundary) was located at approximately 55 degrees N palaeolatitude to the south of the Williston Basin. CLAMP estimates indicate that precipitation increased significantly in all areas sampled directly after the K-T boundary event, especially in the southern Rockies. Precipitation levels decreased somewhat after this initial peak but remained high throughout the early Palaeocene. Evidence from this and other studies suggests that seasonality increased from the latest Cretaceous into the Palaeocene and was most pronounced in central and northerly areas of the North American continent.

We used these velocity estimates to infer slip rates on two major Quaternary faults within the eastern California shear zone (ECSZ), the Hunter Mountain and Death Valley faults. The sum of slip rates across the two faults is well determined at 5 + or - 1 mm/yr (1-sigma ). Between 3 to 5 mm/yr of this motion appears to be accommodated along the Death Valley fault, implying 30-50 m of strain accumulation over the next 10,000 yr. If so, there is potential for 5 to 10 M (sub w) 6.5-7.5 earthquakes during this period, a finding consistent with paleoseismological studies of the fault zone. Yucca Mountain, which lies 50 km east of the ECSZ, is the proposed location for the disposal of high-level nuclear waste in the United States.

I. Controls on phytoplankton growth AN - 17276858; 4479738 AB - Experiments to measure phytoplankton growth rates and microzooplankton grazing rates, both with and without additions of nutrients, were conducted over a 5 yr span to determine the relative roles of physical factors, nutrients, and microzooplankton grazing in regulating phytoplankton pigment biomass in the Rhode River estuary (Maryland, USA). Microzooplankton grazing rate was overall only weakly correlated with phytoplankton growth rate, although fluctuations in the rates appeared to parallel one another for restricted periods. Grazing was about 73% of growth rate at ambient nutrients during 1995, a year in which the two were correlated. In winter and early spring, phytoplankton growth rates were low and unaffected by nutrient additions. In late spring, stimulation of growth by nutrient addition was more common, but microzooplankton grazing was partially effective in relieving nutrient limitation. Growth enhancement by nutrient addition was most common in summer, and microzooplankton grazing was less effective at relieving nutrient limitation. P or N addition stimulated phytoplankton growth in late spring and autumn, but only N addition stimulated growth in summer. Temperature constrained upper bounds of observed growth rates throughout the year, but many observed growth rates were far below the temperature-dependent maximum, even with nutrients added. Considered as a single group, temperature-normalized growth rates were poorly related to in situ daily photon flux; but the rates appeared to fall into species-dependent higher and lower groups. The higher growth rates were statistically associated with the diatoms Thalassiosira pseudonana, Thalassiosira sp., and Nitzschia longissima. The lower growth rates were associated with the dinoflagellates Gyrodinium uncatenum and Prorocentrum minimum. Results suggest that interpretation of bioassay experiments requires consideration of both grazing effects and species composition of the phytoplankton community.

Most of these NIS invasions result from anthropogenic dispersal. Although the relative importance of different dispersal mechanisms varies both spatially and temporally, the global movement of ballast water by ships appears to be the largest single vector for NIS transfer today, and many recent invasions have resulted from this transfer. The rate of new invasions may have increased in recent decades, perhaps due to changes in ballast water transport. Estuaries have been especially common sites of invasions, accumulating from tens to hundreds of NIS per estuary that include most major taxonomic and trophic groups. We now know of approximately 400 NIS along the Pacific, Atlantic and Gulf coasts of the U.S., and hundreds of marine and estuarine NIS are reported from other regions of the world. Although available information about invasions is limited to a few regions and underestimates the actual number of NIS invasions, there are apparent differences in the frequency of NIS among sites. Mechanisms responsible for observed patterns among sites likely include variation in supply of NIS, and perhaps variation in properties of recipient or donor communities, but the role of these mechanisms has not been tested.

The proportion of yearling males increases as relative abundance decreases toward the margins of the breeding range. Geographic clines in age structure are hypothesized to correlate with gradients in habitat quality radiating from the Appalachian Mountains, the probable axis of source populations. Data from the southern Appalachians suggest that despotism of older males may impose a ceiling on the proportion of yearlings in saturated high-quality habitats, regardless of local productivity. Populations that exhibit low variance in yearling recruitment and high population densities may fall toward the "source" end of the "source-sink" continuum, and vice versa. It is hypothesized that the regional distribution of source and sink populations of the Black-throated Blue Warbler might closely mirror the prevalence of successful multiple brooding.

Recent phylogenetic studies of some bees contradict this assumption, and more examples are known or hypothesized in other animals. Social behavior can be lost to give rise to species that are secondarily solitary. Studies of the conditions that lead to the suppression or loss of social behavior can help to illuminate those factors that lead to its origins and maintenance.

During the Paleozoic, silicified fossil occurrences do not significantly correlate with the amount of shelf chert, outcrop area, time, duration of geologic intervals, or carbonate rock volume. This substantial drop in numbers of silicified fossils coincides temporally with increased importance of aragonite faunas following the end-Permian extinctions. However, qualitative measurements of secular changes in abundance and diversity of siliceous sponges are consistent not only with the post-Paleozoic decline in fossil silicification, but also with fluctuations in the amount of silicified fossils throughout the Paleozoic. The facies distribution of silicified fossils in the Permian of West Texas also suggests that the distribution of silicified fossils may reflect the occurrence of siliceous sponges. The decline in silicified fossils after the Permian may be related to a concomitant rise in offshore bedded chert deposition and movement of the locus of biogenic silica formation from nearshore to offshore regions beginning in the Triassic, rather than with the expansion of diatoms in the Cretaceous.

Relative abundance of species was significantly different between life and death assemblages, and zonation patterns (in species relative abundance, coral growth form, and diversity) present in the life assemblages showed both similarities and differences to those found in the death assemblages. The difference in species distribution patterns between life and death assemblages is shown by a striking growth form bias in the death assemblage: species with massive growth forms are underrepresented in the death assemblages in both environments, whereas branching, encursting, and plate growth forms are overrepresented in the death assemblages. Several factors may be involved in the life and death assemblage differences: greater degrees of time averaging than in previously studied reef settings, changes in the life assemblage such that death assemblages record previous life assemblages more faithfully than present ones, and undersampling of massive corals in death assemblages. Comparison of species richness and the Shannon-Wiener index of diversity between life and death assemblages produced unexpected results. In general, death assemblages showed higher diversity than did life assemblages, more in accordance with previous studies of shelly molluscan faunas of temperature and tropical level-bottom marine communities than with those of shallow-water coral reef communities. Because our results differ from previous studies of community preservation in coral reefs, we recommend that paleoecological studies of aquatic ecosystems be accompanied by preservational assemblages from the same or similar environments. Our results point to the subtleties involved in interpreting coral death assemblages and suggest that these assemblages may contain as much or more information on recent changes in the living reef as they do on the future composition of the fossil reef assemblages.

Broadband visible (PAR) and ultraviolet radiation (UVB) were measured around midday in midsummer in an old-growth Douglas-fir/Western Hemlock forest in the Cascade Range in southern Washington using sensors suspended from the gondola of a large tower crane. Patterns of vertical transmittance varied greatly between locations and showed abrupt transitions from bright to dark conditions at varying heights. The average light field in this canopy with trees to 60 m was resolved into three functional zones. Above 40 m from the ground is a "bright zone," where light was reliably intense and predominantly in the direct beam component, and below 12 m, a "dim zone," where light was reliably low and mostly diffuse. Between these levels is a "transition zone," with a steep vertical gradient in light transmittance, high horizontal variation, and a mixture of beam and diffuse components. The pattern of UVB light was very similar to that of PAR. From the general transmittance profile the vertical structure of the canopy was estimated to have a peak density of foliage at 12 m (less than one quarter of the stand height) with declining densities above and below. The "bottom-heavy" canopy structure found in this study differs markedly from the "top-heavy" profiles reported from managed or young stands.

Ninety-two ornithologists from the Americas and Eastern Europe responded to our survey. Eighty genera and 10 families representing 17 orders, primarily Procellariiformes, Falconiformes, Psittaciformes, Cuculiformes, Piciformes, and Passeriformes, were cited as containing malodorous or uniquely odorous birds. Two orders (Opisthocomiformes and Trogoniformes), five families (Procellariidae, Cuculidae, Bucconidae, Picidae, and Furnariidae), and one subfamily (Drepanidinae) were reported to us as either containing many odorous species or consisting primarily of them. Thirty genera and three families representing 13 orders, primarily Passeriformes, were reported to us as unpalatable. The birds cited in our survey and those previously reported as odorous and/or unpalatable are tabulated. Our survey and review point to a number of taxa that may use chemicals to deter predators, although we acknowledge that compounds imparting aversive or unique odors or flavors may arise for a variety of reasons, e.g., as dietary by-products.

When these biases were accounted for, results indicated that 58 to 77 percent of the mammal species were replaced between 3.0 and 1.8 million years ago (Ma). Overall diversity increased from 3.0 to 2.0 Ma but then declined.

Bush may have been overly apprehensive in eschewing federal funds, because large institutions can shelter abstruse research while supporting diverse national & regional infrastructures.

While present European governments consider the treaties as anachronistic colonial documents, the Maroons consider them as sacred charters, because they were backed by "blood oaths." It is argued that the significance of the treaties can best be understood when interpreted with reference to the oath-taking procedures of the Maroons' African ancestors. It is suggested that combining history & comparative ethnography can achieve a more balanced perspective on the treaties, the status of which remains unresolved in those countries where Maroons have survived as distinct populations until today. 3 Figures, 60 References.

An extensive survey was conducted by ORSTOM between 1991 and 1992 to obtain baseline information on the shorefishes. A total of 653 taxa among 72 families are now documented from this area. The most diverse families are the Labridae (69 species), Pomacentridae (58 species), Gobiidae (54 species), Serranidae (39 species), Chaetodontidae (31 species) and Apogonidae (28 species). The absence or very low diversity of some families (Clupeidae, Nemipteridae, Siganidae) or genera (Abudefduf, Neopomacentrus) is similar to findings for other isolated islands of the Coral Sea. Of the 653 species recorded from Ouvea, 51 species have not been reported from New Caledonia, a large high island to the South. Only one endemic species, Luzonichthys williamsi, has been recognized among the shorefishes at Ouvea. A number of Pacific Plate endemic species were recorded at Ouvea, which is positioned on the Australasian Plate to the south of the edge of the Pacific Plate. Antennarius duescus, previously known from three specimens taken at the Hawaiian Islands, is recorded from a single specimen taken at Ouvea. Another antitropical distribution pattern is exhibited by Dinematichthys riukiuensis, which is known to occur at Fiji, Ouvea and Queensland in the South and from Okinawa.

Extensive sampling of this deposit at the local scale was undertaken to assess the species richness and spatial distribution of leaf megafossils in a well-dated Paleocene assemblage. The megafossils were recovered from a series of ten quarries in a single fossiliferous horizon composed of fine-grained claystone that represents deposition in a shallow floodplain pond. Early and middle Paleocene leaf localities from the northern Great Plains are typically depauperate; this deposit was no exception, yielding only 28 distinct leaf morphotypes from a collection of 5,650 specimens (average: 10.6 morphotypes/quarry). Significant differences in the numbers of specimens per morphotype were observed. Four species, Corylites sp. (37.66%), Archeampelos acerifolia (33.93%), Metasequoia occidentalis (18.35%), and Fortuna cf. F. marsilioides (5.29%) comprised >95% of the specimens recovered. Megafloral dominants were fairly consistent from quarry to quarry indicating that this vegetation was relatively homogeneous at the scale of the local community. Detrended Correspondence Analysis indicates that there is no environmental gradient apparent within this community. This extremely well-sampled and laterally extensive leaf site supports the view that the late Paleocene (Tiffanian) flora of the northern Rockies is depauperate compared to megafloras of the Late Cretaceous and late Paleocene (Clarkforkian).

Small juveniles are particularly susceptible to predation, and they often settle in the high intertidal where predation pressure is relatively low. Growth conditions in the high intertidal are, however, only suboptimal compared to the low intertidal. Juvenile amphipods Leptocheirus pinguis usually remain in their mother's burrow for extended time periods growing to average sizes of 4-6 mm during this extended parental care. In laboratory experiments, more juvenile amphipods survived in controls than in predator additions. In the predator treatments, most adult amphipods survived while many juveniles disappeared. Medium-sized juveniles (6-10 mm size) that had already established their own burrows emigrated in large numbers from the predator treatments whereas most of the adult females remained as residents in these trays. Juvenile L. pinguis survived periods where they are most susceptible to epibenthic predation in the protected burrows of their mother. Extended parental care enables juvenile amphipods to recruit immediately into the adult habitat with a good survival chance. It is hypothesized that some small soft-bottom infauna find protection in the burrows of other infauna, medium-sized infauna is most likely to engage in escape reactions, whereas large infauna build their own, deep, burrows, safe from epibenthic predators.

This view emphasizes the importance of identifying conflicts of interest between the partners, and then attempting to quantify the effects of factors that influence costs and benefits to each. The natural history of the species fig-fig wasp pollination mutualisms permits such measurements. However, previous attempts to document the presumed tensions, which are expected to result in a negative relationship between the production of viable seeds and pollinator wasp offspring, have met with mixed results, casting doubt on the existence of the conflict. Here, we present hierarchical analyses of 929 fruits sampled from 30 crops representing nine species of monoccious New World figs. These analyses control for the confounding influences of variation in (1) pollination intensity (numbers of foundress pollinators); (2) flower number per fruit; and (3) the proportion of those flowers that develop, on seed and wasp production, both among and within crops. We thereby show that a negative relationship between the production of viable seeds and wasps is, in fact, ubiquitous, thus documenting this underlying tension inherent in the mutualism. We suggest that complex interactions of variables that influence costs and benefits are likely to be a general property of most mutualistic systems.

These birds are thought to have occupied the role of large herbivores in a wide range of terrestrial habitats. A collection of coprolites from one of the species (Thambetochen chauliodous) was obtained during excavations in Holocene cave sediments on the island of Maui. The chemical composition and pollen and spore content of the coprolites are analysed and compared with pollen/spore spectra from the cave sediments and from recent goose scats. The results support the contention that these birds were primarily folivorous, and further suggest that ferns were important in the diet. The coprolites have a very fine texture that may result from efficient hindgut fermentation and digestion of plant fibre. Our data are discussed in the light of a recent hypothesis of plant/herbivore coevolution between extinct avian herbivores and native Hawaiian lobelias. The loss of large native herbivores, as well as other changes in vertebrate trophic structure due to extinctions over the past few thousand years, may still be affecting ecological processes in areas of the Hawaiian islands with native vegetation.

A VNTR (variable number of tandem repeats) genetic "fingerprinting" marker was used to infer relatedness among mapped plants in two populations. Band sharing within and between populations estimated F' sub(ST), an approximate measure of F sub(ST). Regression models were used to analyze the relationship between band sharing and spatial separation in tidal elevation and horizontal distance, as well as the relationship of fecundity differences with band sharing and spatial distance. Populations differed in band size frequency distributions and mean number of bands per profile and, therefore, likely differed in effective population size. F' sub(ST) was estimated at 0.0678 and was significantly greater than F' sub(ST) among randomly constructed subpopulations. Band sharing decreased 0.13% per meter in one population but showed no significant relation to distance in the other. In the population with significant IBD band sharing increased with increasingly different tidal elevation, contrary to an adaptive hypothesis, possibly due to directional gene flow or drift. Deme sizes were approximately 25 meters and greater than 100 meters, spanning larger areas than the entire environmental gradient. Fecundity differences were not associated with spatial parameters or band sharing. Unequal potential maternal fecundity measured as variance in number of seeds per maternal family was a significant source of genetic sampling variance. The VNTR marker employed is capable of detecting adaptation as identity by descent in ecological time and is an appropriate method for estimating the net evolutionary fate of polygenic traits. The results show that the net balance between selection along an environmental gradient and the effects of IBD and unequal maternal fecundity favor genetic differentiation by random processes in populations of Limonium.

Moran's paintings of this region, as well as later canvases of the Grand Canyon, Zion Canyon, and the Tetons, depict a raw and beautiful wilderness prior to settlement and development. The trip was sponsored by the government to gather information on lands and resources as they pertained to development potential. Moran's paintings helped spawn a new interest in nature art, and were instrumental in convincing Congress to preserve Yellowstone as a national park in 1872.

It is also released through industrial emissions, and is a component in smog and acid rain. Nitrogen is continuously formed into compounds and then broken within the natural nitrogen cycle, as it moves from air to soil to plant matter and back to air. Most of the four billion tons of nitrogen fixed on land are contained by bacteria, much of which live within the roots of legumes. Farmers plant legumes to increase the nitrogen availability in the soil, an important component of plant growth. Nitrogen fertilizers serve this function as well, although some amount is returned to the air and some is leached into surface or groundwaters. The nitrogen cycle is altered by the human activities of massive deforestation, land reclamation, emissions, and fertilizer applications.

Over two million lobster traps are currently distributed throughout Maine, each containing enough bait to contribute to 40,000 tons of bait added to the sea each season. Numerous shellfish species in addition to lobsters feed upon this bait. The catch is the mainstay of 7362 registered lobstermen, who continue to haul in record catches each year. This self-reliant population has a multi-generational history of lobster harvesting, varying only slightly as new regulations are imposed and markets change. Growth in the industry in the 1940s and 1950s was followed by decline in the 1970s, leading to a sustained disagreement between lobstermen and the scientists and regulators governing catches. Despite the claims of scientists that the fishery is in decline, record harvests continue.

The calculated average influx of pollen rain from the native Atlantic rain forest is 12,465 pollen grains cm (super -2) yr (super -1) . The influx from the + or -50 years old and from the 7 years old secondary forest is relatively low (4112 and 3667 grains cm (super -2) yr (super -1) , respectively) compared to the undisturbed rain forest. The occurrence of pollen grains of herbs and fern spores is significantly higher in the secondary forests than in the undisturbed rain forest. Pollen rain in the rain forest is very variable due to local effects. Therefore, results from single terrestrial pollen traps and surface samples from tropical forests should be cautiously applied to the interpretation of fossil pollen records. They can give an incorrect impression of the vegetation and cannot be used as representative data.

Prevalence in five species of xanthid crabs was measured at several spatial and temporal scales along the east coast of North America. The parasite infected Panopeus lacustris, P. simpsoni, P. obessus, Eurypanopeus depressus, Dispanopeus sayi (reported as a host for the first time), and Rhithropanopeus harrisii, but did not infect P. herbstii. The overall prevalence of infection in over 10,000 crabs was low (< 1%); but prevalence exhibited significant large scale geographic variation from 0-83% in the parasite's disjunct distribution along 2750 km of coast and 14 degrees of latitude from New Jersey to western Florida. The introduced range of the parasite included most of Chesapeake Bay, outer Delmarva Peninsula, and North Carolina sounds; but the parasite was not found from South Carolina to Cape Canaveral, Florida. The native range extended from the Gulf of Mexico and eastern Florida up through the Indian River Lagoon. Significant temporal variability of infections occurred between 2 yrs along the geographic range of sampling, with the parasite occurring sporadically (0-47%) in introduced regions of North Carolina and (0-83%) in coastal Virginia. The prevalence of parasitism also exhibited significant local variation among sites within the introduced region of Chesapeake Bay (0-91%) and the native region of the Indian River Lagoon, Florida (0-9%). Parasite prevalence within the Indian River Lagoon exhibited long-term (12 yrs) relative temporal stability at about 7.5% in P. lacustris. In contrast, the parasite exhibited epidemic out breaks (0-72%) in a 15-yr record at the Rhode River subestuary of Chesapeake Bay following its slow spread over 200 km in 30 yrs from introduction in the lower bay in 1963. Size of infected hosts was relatively constant for each crab species, resulting in all sizes of R. harrisii and E. depressus being infected but larger P. lacustris not being infected. Despite the parasite's impact on crab reproduction, the host-parasite interaction is apparently stabilized by shifting combinations of four factors: host species composition; recruitment dynamics, especially slow parasite dispersal; patchy host dispersion in oyster reefs; and reservoirs of uninfected hosts resulting from refuges in host size (e.g., large P. lacustris) or host habitat distribution (e.g., low salinity for R. harrisii).

Twenty-four, 3-cm-deep soil samples were collected on 30 m transects radiating out from each of the trees in each of four time-intervals through the year, and four 21-cm-deep samples were collected beneath the focal tree crowns. In the surface 0-3 cm of soil, germinable seed densities of all species combined declined from a peak of 1090 seeds m super(-2) in the mid-wet season in August, to 330 seeds m super(-2) by the end of the wet season in November. In contrast, at soil depths >3 cm, there was little variation in soil seed bank density through the year. Some variation in soil seed bank density for individual species could be accounted for by distance to reproductive conspecifics. Among species, abundance in the soil was negatively correlated with seed size. Seed persistence varied greatly among species at this site; after 1 y of burial in mesh bags, seed germinability of four species was near zero, while four other species showed no consistent decline in seed germinability after >2 y of burial. For at least one species, Trema micrantha, prolonged seed dormancy was also possible under natural conditions.

Disturbance pits provided unequivocal indicators of ray feeding activity, and pits were counted on a plot (250 m x 500 m) which had prey density mapped in a 200 cell (25 m x 25 m) grid. Although foraging response increased significantly with prey density treated as a nominal (class, ANOVA-type) variable, treating bivalve density as a ratio scale (continuous, regression-type) variable provided more information about characteristics of the response. Eagle rays exhibited a nonlinear segmented response to prey density, in which ray foraging activity was low and independent of prey density at low Macomona densities, while foraging increased sharply above a threshold density of prey but did not reach satiation at the highest prey densities in our site. By counting ray pits repeatedly over a 31 day period, we showed that the levels and slope of the foraging response (no. of ray pits per 707 m super(2) per 4 days) varied temporally during the season, but the nonlinear characteristic and the threshold of prey density were consistent. Correlation analysis showed that the distribution of bivalve prey and ray foraging was spatially constant during the season. Comparison of 3 estimators of prey density showed that a fitted polynomial density was the best predictor of ray foraging, and indicated that rays were responding to prey patches on a scale of 75-100 m. The temporal features of the response to prey density were incorporated into a nonlinear segmented model and integrated with respect to time for each cell of the study grid. The impact of ray foraging estimated from the integral indicated that only about 1.6% of the Macomona population was consumed and 5.0% of the total plot was disturbed by rays during one month of study. However, the nonlinearity of response indicated that foraging impacts were concentrated disproportionately on high density patches of prey, which suffered up to 4% mortality and 13% disturbance. Macomona gained a refuge from predation and disturbance at low density, which would stabilize prey populations and even out prey distribution.

Although composed of a vast assemblage of large and small islands, the Eastern Arctic differs from other "oceanic" environments where modern biogeographical work has been pioneered. This paper outlines conditions which make the Eastern Arctic suitable for biogeographical study and considers the nature of "islands" as analytical constructs rather than as discrete entities. Biogeographical concepts are considered in relation to the "core-periphery model" that has been the organizing principle for interpreting patterns of Eastern Arctic culture history. Abstractions, aspects, and conclusions reached from these studies outline some of the opportunities available for application of more directed anthropological biogeographical work in the future.

Previously there has been scattered and anecdotal evidence documenting oribatid mite detritivory in Pennsylvanian plant tissues. This study evaluates the incidence of oribatid mite damage for seven major coal-ball deposits from the Illinois and Appalachian sedimentary basins, representing a 17 million year interval from the Euramerican tropics. Although this interval contains the best anatomically preserved plant tissues with oribatid mite borings in the fossil record, coeval oribatid mite body-fossils are absent. By contrast, the known body-fossil record of oribatid mites commences during the Middle Devonian, but does not reappear until the Early Jurassic, at which time mite taxa are modern in aspect. All major plant taxa occurring in Pennsylvanian coal swamps, including lycopsids, sphenopsids, ferns, seed ferns and cordaites, were consumed by oribatid mites. Virtually every type of plant tissue was used by mites, notably indurated tissues such as bark, fibrovascular bundles and especially wood, as well as softer seed megagametophytic and parenchymatic tissues within stems, roots and leaves. Significant evidence also exists for secondary consumption by mites of tissues in macroarthropod coprolites. Our data indicate that oribatid mites consumed dead, aerially-derived plant tissues at ground level, as well as root-penetrated tissues substantially within the peat. Oribatid mites were important arthropod decomposers in Pennsylvanian coal swamps of Euramerica. The wood boring functional-feeding-guild was expanded by insects into above-ground, live trees during the early Mesozoic. New food resources for insect borers resulted from penetration of live tissues such as cambium and phloem, and the invasion of heartwood and other hard tissues mediated by insect-fungus symbioses. Termites and holometabolous insects were prominent contributors to this second wave of wood-boring, exploiting gymnosperms and angiosperms as both detritivores and herbivores. An earlier emplacement of oribatid mites as detritivores of dead plant tissues continued to the present, but without a documented trace-fossil record.

Calculated T and P are highest for xenoliths from Ventura-Espiritu and Durango ( approximately 1075 degrees C, 17-20 kbar) which are near the centre of the Tepehuano tectonic terraine. Spinel-pyroxene clusters (decompression reaction products of garnet + olivine) are only found in these fields and only in xenoliths with calculated P >> 15 kbar.T and P are lowest ( approximately 1030 degrees C, 10-15 kbar) for the Santo Domingo and San Quintin fields. Calculated oxygen fugacities increase from SE to NW and the lithosphere closest to the Mesozoic-Cenozoic palaeotrench has been most affected by slab-derived, oxidized fluids or melts.

We combine high-resolution (3-5 km) 70-cm radar data for the nearside with earlier calibrated full-disk observations at the same wavelength to provide a reasonable estimate of the lunar backscatter coefficient. These data are tested against models for echoes from a buried substrate and Mie scattering from surface and buried rocks. These mechanisms are expected to dominate the 70-cm radar echo, with their relative importance determined by the rock population, regolith depth, substrate roughness, and the loss tangent of the soil. Results indicate that the 70-cm radar echo for the maria comes largely from Mie scattering by rocks buried within the fine soil. Radar scattering from a buried substrate is not likely to greatly affect the observed return. We also compared the 70-cm and 7.5-m radar images to infrared eclipse temperature maps, crater-population age estimates for the maria, and to TiO (sub 2) and FeO abundances inferred from Earth-based telescopic and Clementine multispectral observations. These data imply that (1) the TiO (sub 2) (ilmenite) content of the regolith controls variations in 70-cm depolarized echo strength among mare units, with higher titanium abundance leading to lower echoes; (2) changes in the average 70-cm return for a given TiO (sub 2) abundance between maria of different ages do occur, but uncertainties in the current radar data do not allow us to uniquely distinguish between variations in rock population with age and calibration effects; (3) the 7.5-m radar echoes are controlled by the age of the mare basalt flows, with older deposits having a greater degree of fracturing and higher backscatter. Future mapping at 12.6-cm and 70-cm wavelengths will help to resolve some of the issues raised here. Copyright 1997 by the American Geophysical Union.

The clam, a hard shelled intertidal bivalve, which lives buried in shallow soft substrate, is harvested primarily from beds along the east coast of Tasmania, but can be found along the entire coast. To test the hypothesis that the green crab (Carcinus maenas) is an important predator of the native clam, multiple Katelysia spp. beds were surveyed inside and outside the known C. maenas range to evaluate differences in abundance, size structure and tidal distribution. Additionally, juvenile K. scalarina were planted out in the low mid-intertidal of the clam beds and cage experiments to test the effect of green crab predation were undertaken. Although the survey samples are still being analyzed, one clam bed within the green crab range maintained a relatively dense population of K. scalarina juveniles, but the preliminary outplant and cage results suggest that C. maenas may have a very large impact upon the abundance and distribution of K. scalarina and, subsequently, the fishery.

A research program measured the impacts of the recent green crab invasion within its current range and as the crab invaded new regions to the south and west. Preliminary results suggest that the green crab overlaps spatially with a variety of other crab species in Tasmania, including the grapsid (Paragrapsus gaimardii), the portunid (Nectocarcinus integrafrons), the lycosid crab (Aplyxia) and the soldier crab (Mictyris platycheles). It appears that C. maenas predation is causing high mortality rates for P. gaimardii, N. integrafrons and Aplyxia and significant declines in these native populations. The magnitude of these declines is predicted to increase, with low abundances persisting within the range of C. maenas and similar declines occurring outside the current range of C. maenas, in association with future invasion.

Initial observations found that the conical B. australis shells are very common in the shell hash at several study sites, including Barilla Bay, Lord's Point and Humbug Point, Tasmania (Australia), although a live population has been found only at Barilla Bay, where Carcinus maenas are not yet established. Results of outplants and cage feeding experiments conducted to determine if B. australis is a prey item of C. maenas indicated that, although predation has been observed in a laboratory setting, B. australis is not a significant prey item of C. maenas.

N1 - Last updated - 2015-03-24 ER - TY - JOUR T1 - The fate of carbon in grasslands under carbon dioxide enrichment AN - 16002694; 4082366 AB - The concentration of carbon dioxide (CO sub(2)) in the Earth's atmosphere is rising rapidly, with the potential to alter many ecosystem processes. Elevated CO sub(2) often stimulates photosynthesis, creating the possibility that the terrestrial biosphere will sequester carbon in response to rising atmospheric CO sub(2) concentration, partly offsetting emissions from fossil-fuel combustion, cement manufacture, and deforestation. However, the responses of intact ecosystems to elevated CO sub(2) concentration, particularly the below-ground responses, are not well understood. Here we present an annual budget focusing on below-ground carbon cycling for two grassland ecosystems exposed to elevated CO sub(2) concentrations. Three years of experimental CO sub(2) doubling increased ecosystem carbon uptake, but greatly increased carbon partitioning to rapidly cycling carbon pools below ground. This provides an explanation for the imbalance observed in numerous CO sub(2) experiments, where the carbon increment from increased photosynthesis is greater than the increments in ecosystem carbon stocks. The shift in ecosystem carbon partitioning suggests taht elevated CO sub(2) concentration causes a greater increase in carbon cycling than in carbon storage in grasslands.

Calorimetric methodology was developed and the enthalpies of formation and of oxidation-reduction reactions relating the oxides manganosite, hausmannite, bixbyite and pyrolusite were determined. Calculation of oxidation-reduction equilibria agree with previous data and validate the methodology. The enthalpies of stable and metastable MnO (sub 2) and MnOOH polymorphs, pyrolusite beta -MnO (sub 2) , ramsdellite MnO (sub 2) manganite Gamma -MnOOH and groutite alpha -MnOOH are reported. Very small energetic differences between the Mn oxides suggest that the framework stability is controlled by the nature of the Mn-O bonding rather than the openness of the crystal structure.

S. Atlantic continental slope AN - 52659257; 1998-002130 AB - Foraminiferal and lithologic characteristics of sediments from 14 Deep Sea Research Vessel Alvin push cores have been used to investigate modern sedimentary processes in Wilmington and South Heyes submarine canyons. A nearly ubiquitous occurrence of abundant foraminiferal species is over-printed by depth-related variations in abundance. Most species are native to lower bathyal and abyssal depths and are in situ. The occurrence of neritic species is attributed to erosion of material from slump blocks of neritic origin which now comprise the steep and undercut walls of Wilmington Canyon. In Wilmington Canyon, the consistent distribution of foraminifera contrasts with marked variations in lithologic characteristics observed at channel meanders. These variations are attributed to relatively minor mass-wasting processes and to effects of bottom (perhaps tidal) and/or low density current action, more active at constrictions and along the steep walls of meanders. These processes are less prevalent in South Heyes Canyon as indicated by markedly lower compositional variations, a low percent of clastic material, and a lower rate of sediment accumulation. This is, in part, a function of the linear morphology and less varied relief of South Heyes Canyon. There is no firm evidence for prevalent high energy downslope transportation events (i.e., erosive high-density turbidity currents) in either Wilmington and South Heyes Canyons during the past 200-400 years represented by the cored material.

The late-glacial period, which starts at 12,500 (super 14) C yr BP, indicates the predominance of a diverse grassland vegetation (campos) with scattered stands of Araucaria forest and Atlantic rain forest, probably growing in valley bottoms. This suggests 3 to 5 degrees C colder and drier climates than at present. Judging from the absence of charcoal, fires must here been rare during late-glacial times. The early and mid-Holocene (until 2850 (super 14) C yr BP) is marked by a predominance of campos vegetation on the highlands and expansion of tropical rain forest trees in the valleys, indicating warm climates and perhaps an increase in annual precipitation compared to the late-glacial. A migration of Araucaria forest from the valleys onto the highlands did probably not occur. Seasonal drought is probably the major factor explaining the absence of an expansion of Araucaria forests on the southern Brazilian highlands in the early and mid-Holocene. Palaeofires were more frequent at the beginning of the Holocene, probably ignited by Amerindians at that time. First expansion in the valleys or an initial migration of Araucaria angustifolia from valleys into the Serra Campos Gerais highland occurred during the late Holocene (2850-1530 (super 14) C yr BP), indicating a wetter climate with a shorter dry season. Fires during this period had the highest frequency and may have influenced the migration of Araucaria into the campos areas. A marked expansion of Araucaria forest, forming a mosaic of grassland and Araucaria forest patches on the highlands, took place only in the last 1500 years. This suggests onset of a high precipitation climate without a strong annual dry season. Fires were also less frequent. Logging of Araucaria forests occurred during the last centuries.

Here we examine interannual variability in chlorophyll and nutrient concentrations in recent years. Years are classified as having an average bloom, extraordinary bloom, or no bloom, and patterns of nutrient concentration are described for each category. To determine processes associated with the different categories of behavior, we performed a generalized sensitivity analysis of a model of nutrient-limited phytoplankton net growth which was previously shown to simulate the chlorophyll concentration and the observed pattern of shift from P to N limitation in an average year. Model parameters controlling the delivery of N and P by the environment and the biological utilization of nutrients by the phytoplankton were drawn from random distributions based on literature reports or, where available, data from the Rhode River. Model output for each parameter set was classified according to which, if any, of the classes of bloom it exhibited. Environmental processes most responsible for the variability in predicted spring blooms were the rate of phosphorus release from the sediment, the timing of nitrate depletion at the seaward boundary, and the maximal nitrate concentration at the boundary. Simulation of bloom failure was most strongly associated with low rates of phosphorus release from the sediment. Phytoplankton physiological parameters most responsible for variability in categories of behavior were the nitrogen:chlorophyll conversion factor, and the maximum internal storage capacity for phosphorus. Blooms of extraordinary magnitude were associated with low nitrogen:chlorophyll ratios and high storage capacity for phosphorus. Results help identify key processes and parameters in need of further understanding as well as possible points for managerial intervention.

The formation of the settlement-mark was validated to occur at settlement in 2 pomacentrids, Pomacentrus amboinensis, P. nagasakiensis, and less conclusively in 13 other species from 7 families. Within these species, 3 distinct settlement-mark durations were identified: a single-increment mark (P. amboinensis, P. nagasakiensis); a 2-increment mark (P. coelestis); and a zonal, 14-increment mark (Acanthurus sp. 2, probably A. blochi). The structure of settlement-marks for P. amboinensis and P. nagasakiensis were compared among 4 to 5 locations on the northern Great Barrier Reef, Australia (maximum of 20 km apart). Otolith increment profiles differed minimally over spatial scales of 20 km in these species, with Lizard Island fish possessing increment profiles different to those from other locations. This pattern of minimal variation in profiles occurred despite the fact that the planktonic larval duration of one species (P. nagasakiensis) differed among locations (range of mean values: 22.4 to 26.3 d). Further, at Lizard Island, increment profiles of P. amboinensis showed statistically significant, although minor, differences among local populations around the island and between successive lunar recruit cohorts. Our evidence suggests that the structure of the increment transitions associated with settlement are taxon specific, although the optical contrast of settlement-marks (determined by increment width) may show subtle spatial and temporal variation.

Lake Surucucho (Llaviucu) lies at 3180 m on the Amazonian flank of the Andes and above the glacial age pollen record from San Juan Bosco at 970 m. The Surucucho pollen record is interpreted as showing treeless vegetation in glacial times, advance of treeline in late-glacial time, and Holocene development of modern Andean forests. Combining the Surucucho and San Juan Bosco records shows that Andean vegetation was affected by glacial cooling at all elevations. Vegetation did not move up and down slope as belts. Rather, plant associations were reformed as temperature-sensitive species found different centers of distribution with changing temperature.

Opportunities for carbon sequestration with forestry activities have been analysed in detail primarily in industrialized nations, mainly because of data availability. This article presents a model that simulates a tropical forest stand in its role as a source of income and as a carbon store, and quantifies the potential for and cost-effectiveness of carbon sequestration through modifications of management practices. Results suggest that financing modifications of forestry practices may achieve net carbon sequestration in a relatively cost-effective way. Tropical countries with extensive forest resources may be in a position to offer cost-effective net carbon sequestration options.

(Fabaceae) was studied in the seasonally moist forest of Barro Colorado Island, Panama. Seeds with 60% of their cotyledonary mass removed did not suffer a reduced probability of germination compared to unmanipulated seeds and seeds infested with up to eight insect larvae germinated as well as uninfested seeds. Unmanipulated seeds were able to consecutively produce up to four functional resprout shoots after excision of the initial, and subsequent, fully expanded shoots. Even seeds with up to 60% of their reserves removed showed some capacity to resprout. Less than 10% of seeds we encountered in the field 2 mo after the end of the fruiting season were in a viable state, with the majority (55%) of mortality attributable to insect or pathogen damage. Of the 46 seeds that were viable, 30% had suffered partial removal of seed reserves similar to our manipulation treatments. These results indicate that P. copaifera seeds are capable of tolerating severe seed and shoot damage. The selective advantage conferred by damage tolerance may in part have contributed to the evolution of large seed size in this species.

Crosses were carried out to determine the nature of any reproductive isolation between these two butterflies. A novel analysis demonstrated both strong assortative mating among the pure forms and an unusual example of Haldane's rule: F1 hybrid females (the heterogametic sex) from the cross A. amathea (female) x A. fatima (male) have a reduced tendency to mate. Historically, Haldane's rule has been restricted to hybrid mortality or sterility and most studies have concentrated on taxa (predominantly Drosophila) between which strong barriers to gene flow already exist. Our data suggest that Haldane's rule might be extended to cover any decrease in hybrid fitness and that mating propensity may provide a sensitive and comparable means of assessing such decreases. Other barriers to gene flow were also evident in Anartia: F1 hybrid females have reduced fertility (also a Haldane effect) and larval survivorship was greatly reduced in F2 hybrids of both sexes. These examples of hybrid disruption are expected under the dominance theory of Haldane's rule but do not exclude other explanations.

Marine iguana (Amblyrhynchus cristatus) populations in the Galapagos exhibit 10-fold differences in body mass between island populations. There is also strong sexual size dimorphism, with males being about twice as heavy as females. To understand the evolutionary processes shaping body size in marine iguanas, we analyzed the selection differentials on body size in two island populations (max. male mass 900 g in Genovesa, 3500 g in Santa Fe). Factors that usually confound any evolutionary analysis of body sizes-predation, interspecific food competition, reproductive role division-are ruled out for marine iguanas. We show that, above hatchlings, mortality rates increased with body size in both sexes to the same extent. This effect was independent of individual age. The largest animals (males) of each island were the first to die once environmental conditions deteriorated (e.g., during El Ninos). This sex-biased mortality was the result of sexual size dimorphism, but at the same time caused sexual size dimorphism to fluctuate. Mortality differed between seasons (selection differentials as low as -1.4) and acted on different absolute body sizes between islands. Both males and females did not cease growth when an optimal body size for survival was reached, as demonstrated by the fact that individual adult body size phenotypically increased in each population under favorable environmental conditions beyond naturally selected limits. But why did marine iguanas grow "too large" for survival? Due to lek mating, sexual selection constantly favored large body size in males (selection differentials up to +0.77). Females only need to reach a body size sufficient to produce surviving offspring. Thereafter, large body size of females was less favored by fertility selection than large size in males. Resulting from these different selection pressures on male and female size, sexual size dimorphism was mechanistically caused by the fact that females matured at an earlier age and size than males, whereafter they constantly allocated resources into eggs, which slowed growth. The observed allometric increase in sexual size dimorphism is explained by the fact that the difference between these selective processes becomes larger as energy abundance in the environment increases. Because body size is generally highly heritable, these selective processes are expected to lead to genetic differences in body size between islands. We propose a common-garden experiment to determine the influence of genetic factors and phenotypic reaction norms of final body size.

This prediction is the basis of the recommendation that captive wildlife populations suffering from inbreeding depression be intentionally bred from healthy inbred animals. Yet data on the effectiveness of purging inbreeding depression are few. In this study I present and use two different regression models (an ancestral inbreeding model and a lethal recessive model) to test for the presence of purging effects in 25 captive mammalian populations. Fitness components examined were neonatal survival, survival from neonate to weaning, and litter size. In only one species was purging statistically significant. However, 15 of 17 species that showed inbreeding depression exhibited a slight decline in inbreeding depression in neonatal survival among descendants of inbred animals. These results show a small but highly significant trend of purging on neonatal survival. No trends in purging effects were observed in weaning survival or litter size. The effects were not likely to be strong enough to be of practical use in eliminating inbreeding depression. JF - Journal of Heredity AU - Ballou, J D AD - Dep. Zoological Res., Natl.

Digestion with seven restriction enzymes identified 47 haplotypes in a sample of 326 individuals. Samples collected from reef sites within each location were not significantly differentiated based on Phi sub(ST) or spatial distribution of haplotypes, indicating that dispersal is high over short to moderate distances. Evidence of gene flow is further supported by the low divergence among haplotypes and the lack of any clear geographical structuring among different haplotypes in the gene phylogeny. However, analysis of molecular variance (AMOVA), Phi ? sub(ST) and contingency chi super(2) analyses of the spatial distribution of haplotypes demonstrate the presence of significant broad scale population genetic structure among the four widespread locations examined. RFLP data are consistent with high gene flow between the Philippines and Western Australia and moderate gene flow between the Great Barrier Reef (GBR) and Fiji, but only limited gene flow between either the Philippines or Western Australia and either the GBR or Fiji. The presence of mtDNA structure contrasts with previous allozyme data which suggest that dispersal among widely separated locations is equivalent to dispersal among populations within the highly connected GBR studies. This discordance between patterns of gene flow inferred from these two markers cannot be fully accounted for by differences in effective population size for mtDNA. This might suggest that while mtDNA variation may represent contemporary patterns of gene flow, allozyme variation among populations is yet to reach equilibrium between drift and migration over the range surveyed.

In addition, we found the highest numbers for over half of the common migratory species. Despite the high degree of leaf loss during the late winter, acacia groves do not experience greater declines in insectivorous migratory bird populations than other local habitats. Color-marked individuals of canopy species had a strong tendency to remain resident within a single acacia grove throughout the winter. Management of native acacias on subtropical rangelands for wood products, fodder, and soil improvement would probably directly and indirectly benefit migratory song bird populations. Neotropical acacia woodland is primarily associated with grazing land for livestock which might discourage some from considering acacia management a viable option for migratory bird conservation. However, acacias were probably widespread in recent geologic time under drier conditions with heavy browsing and seed dispersal by a now extinct megafauna. Two observations suggest a foraging advantage for acacia use: the higher density of migratory birds in acacia is a result of higher numbers of canopy insectivores; and acacias are selected by migrants when they occur in mixed habitat. We hypothesize that plant investment in mechanical defenses (thorns) reduces energy available for chemical defenses effective against insect herbivores.

In the process, nitrogen is trapped from release to the atmosphere, and humus is created, thus enriching the soil. Dung beetles have been in evidence since the dinosaurs dominated the earth, and are currently active in African savannas, in tropical rain forests, and in other ecosystems where mammals are prevalent. Dung beetles evolved in parallel with the proliferation of mammals after the demise of the dinosaurs, with beetle species becoming highly adapted to mammalian dung and environmental conditions. Dung beetles move wastes by digging directly under them to form a shaft, or rolling them along. Others lay their eggs directly on the dung. Dung beetles, which are present on all continents except Antarctica, and pose no threats to crops, will be developed for introduction to reduce harmful insect populations.

When the Nature Conservancy bought a 321,000 acre ranch in New Mexico to protect numerous desert and mountain ecozones and the 20 endangered species that live in this habitat, a new breed of ranchers met to address the upwelling of controversy, and to mark new grounds of compromise. The Malpai Borderlands Group was thus formed of a coalition of local ranchers committed to maintaining environmental health in the region. Early priorities were fire suppression strategies, the development of a grassbank, wildlife fencing, reseeding, and habitat preservation for endangered frogs.

After plant senescenceand summer drought, we simulated the first fall rains and examined Ncycling. Growth at elevated CO sub(2) increased root productionand root carbon:nitrogen ratio. Under nutrient enrichment, elevatedCO sub(2) increased microbial N immobilization during wet-up,leading to a 43% reduction in gross nitrification anda 55% reduction in NO emission from soil. ElevatedCO sub(2) increased microbial N immobilization at ambientnutrients, but did not alter nitrification or NO emission. ElevatedCO sub(2) did not alter soil emission of N sub(2)O ateither nutrient level. Addition of NPK fertilizer (1:1:1) stimulatedN mineralization and nitrification, leading to increased N sub(2)Oand NO emission from soil. The results of our study support a mechanisticmodel in which elevated CO sub(2) alters soil N cycling and NOemission: increased root production and increased C:N ratio in elevatedCO sub(2) stimulate N immobilization, thereby decreasingnitrification and associated NO emission when nutrients are abundant.This model is consistent with our basic understanding of how C availabilityinfluences soil N cycling and thus may apply to many terrestrial ecosystems.

AN - 79023743; 9160996 AB - The zebrafish (Brachydanio rerio) was used as a model for basic studies of the chilling sensitivity, permeability and toxicity of cryoprotectants. In both intact and dechorionated embryos, early-stage embryos (1.25, 1.5, 1.75, and 2 h) were more susceptible (P 0.05) this pattern of sensitivity to chilling. Eight-hour zebrafish embryos tolerated short-term exposures to temperatures ranging from 4 to 23 degrees C for 3.5 h with no detrimental developmental effects. The permeability of dechorionated embryos to cryoprotectants was examined by measuring the kinetics of volumetric change at various developmental stages (16 cells to six somites or ca. 1.25 to 14 h postfertilization) at 28.5 degrees C. The dechorionated zebrafish embryo is composed of two complex cellular compartments (i.e., a large yolk and the developing blastoderm). From 40 to 100% epiboly, the volumes of yolk and blastoderm remained constant, ca. 82 and 18%, respectively. However, these volumes changed rapidly after epiboly. For example, at the six-somite stage, the yolk composed 61% of the total volume, whereas the blastoderm composed 39%. When three- and six-somite embryos were placed in 1.5 and 2.0 M cryoprotectants (dimethyl sulfoxide and propylene glycol), osmometric measurement of volume changes indicated no permeation of the cryoprotectants. However, some permeation was observed for six-somite embryos immersed in a 2.0 M methanol solution, but not for 3-somite embryos. For up to 30 min at room temperature, these cryoprotectant solutions were toxic to zebrafish embryos; however, 1.5 M glycerol and ethylene glycol solutions were. We conclude that the complex nature of the zebrafish embryo reduces the effectiveness and predictive value of light microscopical measurements for cryoprotectant permeability studies.

Photoclinometrically derived elevation data across wrinkle ridges were evaluated to determine the sensitivity of profiles to two empirical photoclinometric parameters, the horizontal digital number (HDN) and the scattered light value (SLV). The photoclinometric profiles are extremely sensitive to small variations in HDN. The sense of slope of a profile can be completely reversed over a range in HDN of as little as + or -1. Comparably small variations in the SLV have relatively minor effects on the photoclinometrically derived elevations. The existence of elevation offsets from one side of the ridge to the other, reported in previous photoclinometric studies of martian wrinkles, were not confirmed through photoclinometry. In addition, no evidence of elevation offsets were found in Earth-based radar altimetry profiles across wrinkle ridges. In order to more accurately model wrinkle ridge topography, we controlled photoclinometrically derived elevations with long-wavelength topography obtained from the radar altimetry. The results of this study do not support kinematic models for the origin of planetary wrinkle ridges that involve deeply rooted thrust faults which separate crustal blocks at different elevations. A kinematic model involving buckling of shallow crustal layers into concentric folds that close, leading to the development of thrust faults, is consistent with wrinkle ridge morphology and terrestrial analogs. Recent geophysical studies of terrestrial analogs and the influence of shallow subsurface structures, particularly buried craters, on the localization of many wrinkle ridges on Mars suggest that thrust faults associated with the ridges are confined to the ridged plains material and do not extend into the lithosphere.

Here we report an investigation of female phonotaxis under two levels of light to test the hypothesis that the degree of caution that female tungara frogs exhibit when chosing a mate should be influenced by light intensity. The 82 females tested in both dim light and dark chose 27 times in the dim light and 45 times in the dark (Fig. 1A). Of these 82 females, 32 did not choose in either test, and 22 chose in both. Of the 28 that chose only once, 23 made their one choice in the dark and only five in the dim light. Thus, significantly more females chose in the dark than in the dim light (P < 0.01).

Canid scats are often found during routine fieldwork, but cannot be reliably identified to species. To detect and study the endangered kit fox, we developed mitochondrial DNA markers that can be amplified from small amounts of DNA extracted from scats. We amplified a 412-bp fragment of the mitochondrial cytochrome-b gene from scat samples and digested it with three restriction enzymes. The resulting restriction profiles discriminated among all five canid species and correctly identified 10 'unknown' fox scats to species in blind tests. We have applied our technique to identify canids species for an environmental management study and a conservation study. We envision that our protocol, and similar ones developed for other endangered species will be greatly used for conservation management in the future.

Forty years later, the combined wild and captive population is 120, and captive releases have occurred eight times since 1992. The gradual recovery of the population lends credence to the controversial Endangered Species Act.

Typical of thousands of other scrap operations across the nation, the Denbo firm is a second- and third-generation family operation. Together the scrap industry supplies half of the iron, steel, and copper, 55% of the lead, 33% of the aluminum, and various other metals required by US industry; it also fuels numerous foreign industries. This look at the Denbo operation examines its family history, industrial growth, requirements, and relationships over time, the impact of the recycling industry, typical scrap materials, scrap metal processing, and the market for scrap metals.

Coal balls are concretions that preserve the original peat fabric of the coal seam; they occur within the coal matrix and generally are permineralized with calcium carbonate. Coalified plant cell walls are preserved within the mineral matrix of the coal ball, entombed within the calcium carbonate. Relative carbon allocation was determined by separation of the mineral matrix and organic carbon. Carbon content was determined for replicates of tissues or organs of Psaronius tree ferns, Medullosa pteridosperms, the lycopsid Sigillaria approximata, the small fern Botryopteris forensis, and "whole peat". Unit volume results for tissues and organs were normalized for trunk sections 45 cm in diameter and 1 m long. Psaronius tree ferns were significantly "cheaper" than all other plants due to the large mantle of aerenchymatous roots that made up the bulk of the trunk. Medullosans and small ferns were most "expensive", with the arborescent lycopsid in between. Relative expense of construction closely parallels the inferred ecological role of each plant within ancient coal swamps, deduced from distributional patterns and indicators of habitat conditions. Tree ferns and lycopsids are colonists, medullosans are site occupying forms.

Changes in taxa composition and elevational shifts in high elevation grassland (campos de altitude), Araucaria forest, cloud forest and Atlantic rain forest, all of which can be found in the study area today, indicate climatic changes in the past. Expanded high elevation grasslands, absence of Araucaria forest, cloud forest and Atlantic rain forest during the recorded last glacial period (ca. 35,000-17,000yr B.P.) suggest a climate markedly cooler and drier than today. Development of a Sphagnum peat bog, rare presence of Araucaria forest taxa and existence of a narrow cloud forest and rain forest belt at lower elevations during the late glacial period (17,000-ca. 10,000yr B.P.) indicate a change to a cool and somewhat moister climates. During the early Holocene cloud forest developed close to the study site, reflecting a warm and moist climate on the east facing slopes, but a drier climate on the highland plateau, evidenced by the rare presence of Araucaria and Podocarpus. Only during the late Holocene moisture increases in the highlands, suggested by the higher frequency of Araucaria and Podocarpus. Fires were more frequent during the last glacial than during the Holocene.

Three distinct suites of primitive magmas are recognized on the basis of their geochemistry: 1) calc-alkaline basalts, 2) lamprophyric lavas including minettes, leucitites, spessartites, and kersantites and 3) alkaline basalts with an intra-plate-type (OIB-like) trace element and isotopic signature. All three magma types erupted in close spatial proximity; the lamprophyric and calc-alkaline lavas form a mineralogical and compositional continuum, whereas the alkaline rocks represent an unrelated series. The ultimate origin of the lamprophyric suite is taken to reflect the melting of a phlogopite pyroxenite vein component in the mantle wedge formed by hybridization reactions between peridotite and melts or fluids ascending from the downgoing slab. The geochemistry of the calc-alkaline magmas reflects dilution of this vein component by melts from the peridotitic wallrock. It is concluded that the intraplate-type magmas are chemically unmodified by subduction zone processes and are related to upwelling of asthenosphere to relatively shallow levels in the sub-arc environment.

A total of 33 tintinnid species from 15 genera were identified from ballast water samples. Live tintinnids were observed on occasion. Many of the species that were observed in these ballast water samples have also been found in the nearby Strait of Juan de Fuca, but others have never been reported in the eastern Pacific. The presence of tintinnids in ballast water obfuscates any conclusions about the natural distributions of these species. This study suggests that ballast water has been a vector for tintinnid transport for many years, and that it may no longer be possible to determine the native distributions for many tintinnid species.

The three plantation types (Inga, Gliricidia, and sun) showed high faunistic similarities with each other and were both distinct and depauperate compared to matorral and forest patch habitats. Of all the coffee plantation habitats, Inga shade had the highest diversity. Species associated with wooded vegetation were more common in shade plantations, particularly in Inga. A second census showed a decline in bird numbers that was more pronounced in sun and Gliricidia than in Inga plantations. Overall, differences between the plantation types were small and all coffee plantations were less diverse than traditional coffee farms previously studied in nearby Chiapas, Mexico. The relatively low bird diversity was probably due to the low stature, low tree species diversity, and heavy pruning of the canopy. These features reflect management practices that are common throughout Latin America. The most common species of birds in all coffee plantation habitats were common second-growth or edge species; more specialized forest species were almost completely absent from plantations. Furthermore, many common matorral species were rare or absent from coffee plantations, even sun plantations with which matorral shares a similar superficial structure. Coffee plantations probably will only be important for avian diversity if a tall, taxonomically and structurally diverse canopy is maintained. We suggest this is most likely to occur on farms that are managed for a variety of products rather than those designated entirely for the production of coffee.

The method combines information from back scattered radiation in the Hartley band down to the O sub(3) concentration peak, lower atmospheric information from the temperature structure of the Huggins bands, and a constraint on the total column from the Chappuis bands. The Huggins bands' temperature structure provides altitude information on the ozone distribution that includes clear distinction between stratospheric and tropospheric ozone. Studies presented here include dependence of the retrieved O sub(3) profiles on surface albedo, tropospheric aerosol, and tropospheric O sub(3) content for a range of atmospheric conditions.

This reptile weighs up to 200 pounds and preys on small and large mammals, birds, snakes, fish, and carrion. The dragons are active hunters, and are also capable of ambush. Currently, 3,000-5,000 dragons are alive in the wild, and another 200 live in captive breeding programs, which have increased the world population by 157. The dragon descends from the monitor lizard family. Its survival on islands which do not support large mammalian predators is unusual. The preferred habitat of the dragon is the savanna, and the overlap with tropical monsoon forests. Current threats to the population include poaching, loss of habitat to development, and natural catastrophes such as volcanic eruptions and fire.

Due to subsequent burial by sedimentation, and tectonic uplift of the northern Peloponnesos, the ruined site is now believed to be on land. Since 1988, the search for Helike has been conducted using sonar, bore hole drilling, geophysical survey (including magnetometry and GPR), and excavation. In June 1996 we used GPR in seven areas near the presumed site of Helike. Data collected using GSSI's SIR-2 and monostatic 400 MHz antenna achieved a maximum penetration of 3 m using filters and a running weighted average stack. Despite limited resolution and penetration, we observed several hyperbolic targets. One of these was a tile floor dating from the Roman Era. GSSI's multi-low-frequency bistatic antenna, used in the 80 MHz configuration, achieved depths of approximately 5 to 6 meters in some areas.

When cryptic sponges were excavated, on Guigalotupo reef, San Blas, Panama, exposing them to potential predators, they were eaten by fishes that are generally considered to be herbivores, primarily parrotfishes of the genus Sparisoma: S. aurofrenatum (Cuvier & Valenciennes), S. viride (Bonnaterre), and S. chrysopterum (Bloch & Schneider). Of the 9150 bites observed to be taken by these species during paired (i.e., with sponges versus without sponges) trials conducted in defined feeding areas during 1986, 1987, and 1988, 72% (i.e. 6581 bites) were on cryptic sponges, even though these were only offered during half of the total observation time and never constituted more than 7% of the cover of the feeding observation areas. Individual parrotfish returned over and over to take bites of the exposed cryptic sponges until they were entirely consumed. They vigorously chased each other away from the sponges, but exhibited no such defense of their usual algal foods. A total of 18 sponge species were tested. Of the cryptic and semi-cryptic sponge species tested, only one of six was rejected by the parrotfish. Two of these six sponge species were consistently consumed entirely, and two were consumed entirely whenever their surfaces were sliced off with a razor blade, demonstrating that these sponges concentrate defenses against predators in their surfaces. One semi-cryptic species and one semi-exposed species were fed upon, but not entirely consumed. By contrast, 11 of 12 of the exposed and semi-exposed species were rejected. Cryptic sponges grew out of their cavities in the reef only when protected by seasonally thick mats of macroalgae or by cages that excluded fish.

The shapes and sizes of living leaves are highly sensitive to moisture conditions, and assemblages of fossil leaves of flowering plants have great potential as paleoprecipitation indicators. Most quantitative estimates of paleoprecipitation have been based on a multivariate data set of morphological leaf characters measured from samples of living vegetation tied to climate stations. However, when tested on extant forests, this method has consistently overestimated precipitation. We present a simpler approach that uses only the mean leaf area of a vegetation sample as a predictor variable but incorporates a broad range of annual precipitation and geographic coverage into the predictor set. The significant relationship that results, in addition to having value for paleoclimatic reconstruction, refines understanding of the long-observed positive relationship between leaf area and precipitation. Seven precipitation estimates for the Eocene of the Western United States are revised as lower than previously published but remain far wetter than the same areas today. Abundant moisture may have been an important factor in maintaining warm, frost-free conditions in the Eocene because of the major role of water vapor in retaining and transporting atmospheric heat.

In crabs, males stay with their mates to protect the female from predators because, in some species, mating occurs when she is soft and vulnerable after molting. I tested the relative roles of sperm competition and predation on the duration of the post-copulatory association in the blue crab, Callinectes sapidus. Unpaired females suffered greater predation mortality than paired females and males stayed with the female longer in the presence of predators than in their absence, suggesting that the post-copulatory association protects females during their vulnerable period. However, the association may also occur in blue crabs because of sperm competition since spermathecal contents of females in the field indicate that 12.4% mated twice. Females experimentally mated with two males contained both males ejaculates and each ejaculate had access to the unfertilized eggs, suggesting that the size of a male's ejaculate influences his fertilization rate in a multiply-mated female. Males stayed longest in response to a high risk of sperm competition. Longer post-copulatory associations allowed the first male's ejaculate to harden into a type of sperm plug, which limited the size of a second inseminator's ejaculate in a non-virgin female as compared with a virgin. Males passed larger ejaculates in the presence of rivals and when previous ejaculates were in the female spermathecae, another response to sperm competition. Larger ejaculates may need longer post-copulatory associations before a more effective sperm plug forms. Large males stayed with the female longer, which is consistent with their ability to pass larger ejaculates than small males and suggests that there may be costs to minimizing the duration of the post-copulatory association. In the field, associations last long enough to protect the female during her vulnerable phase and may ensure that the guarding male fertilizes the most eggs in the female, even if she remates. Thus, the post-copulatory association protects female blue crabs from additional inseminators as well as from predators. JF - Behavioral Ecology and Sociobiology AU - Jivoff, P AD - Smithsonian Mar.

Researchers at the National Soil Tilth Lab in Ames, Iowa, examine soil with gas chromatography, mass spectrometry, electron microscopy, and other sophisticated technologies. They monitor precipitation, runoff, and leaching in their test fields; nutrients, organic matter, aggregation, and chemical constituents in the lab. Decomposition processes and the release of nutrients to plants are under study. Vermiculture and its contribution to agriculture is a subject of study, as is the extraction of herbicides from soil samples.

Analyses are presented of target rocks, breccias, suevite, melt-matrix breccia, crater-fill sandstones for major and trace elements, and C, Re and Os isotopes. Four samples only gave Ir contents above the detection limit (0.5-0.8 ppb), though two suevite and two melt breccia samples showed some indication of elevated Ir which might indicate an extraterrestrial component. The structure is identified as a deeply eroded remnant of a meteorite impact event approximately 400-900 m.y. ago; this is based on the distinctive petrographical and chemical characteristics of the impactites. A significant C content of 0.5-1.0 wt.% of the impactites shows an enrichment over the exposed target rocks. Delta ^>13C values of -28.1 to 31.50/00 indicate derivation of this C from the Biri shale present during impact. The structure was metamorphosed at greenschist to ?amphibolite facies during the Caledonian orogeny.

A greater degree of physical and biological alteration occurred in the lower-energy leeward Pioneer Bay site relative to the higher-energy windward Iris Point site. Greater degrees of taphonomic alteration also occurred at 6-7 m than 2-3 m water depth within each site. Clear gradients in the degree of taphonomic alteration of reef corals with reef environment indicate the utility of corals as taphofacies indicators in ancient reef settings. Because greater taphonomic differences between depths occurred at the high wave-energy site relative to the low wave-energy site, differentiation of fossil reef taphofacies might be greatest in high-energy reef settings. Interpretation of ancient reef sedimentary environments may be aided by analysis of taphonomic alteration of reef corals. Massive corals suffered greater degrees of biological and physical alteration than free-living corals which suffered greater alteration than branching corals. The greater taphonomic alteration in more robust massive coral growth forms from Orpheus Island concurs with other studies that have suggested that bioerosion may be related to overall skeletal area and density, and amount of skeleton not covered by living tissue during the life of the coral. In addition, relative differences in production of coral morphotypes might result in a greater number of less degraded branching than massive corals. A possible explanation for the two observations that corals in higher wave energy environments are less degraded than those from lower wave energy environments, and that fragile are better preserved than robust coral growth forms, is the differing amount of post-mortem residence time the corals spend in the "taphonomically active zone".

Leaves produced at the end of the wet season were predicted to have higher photosynthetic capacities and higher water-use efficiencies than leaves produced during the early rainy season. Such seasonal phenotypic differentiation may be adaptive, since leaves produced immediately preceding the dry season are likely to experience greater light availability during their lifetime due to reduced cloud cover during the dry season. We used a construction crane for access to the upper canopy and sampled 1- to 2-month-old leaves marked in monthly censuses for six common tree species with various ecological habits and leaf phenologies. Photosynthetic capacity was quantified as light- and CO sub(2)-saturated oxygen evolution rates with a leaf-disk oxygen electrode in the laboratory (O sub(2max)) and as light-saturated CO sub(2) assimilation rates of intact leaves under ambient CO sub(2) (A sub(max)). In four species, pre-dry season leaves had significantly higher leaf mass per unit area. In these four species, O sub(2max) and A sub(max) per unit area and maximum stomatal conductances were significantly greater in pre-dry season leaves than in early wet season leaves. In two species, A sub(max) for a given stomatal conductance was greater in pre-dry season leaves than in early wet season leaves, suggesting a higher photosynthetic water-use efficiency in the former. Photosynthetic capacity per unit mass was not significantly different between seasons of leaf production in any species. In both early wet season and pre-dry season leaves, mean photosynthetic capacity per unit mass was positively correlated with nitrogen content per unit mass both within and among species. Seasonal phenotypic differentiation observed in canopy tree species is achieved through changes in leaf mass per unit area and increased maximum stomatal conductance rather than by changes in nitrogen allocation patterns.

The annual reproductive cycle of the foxes was reflected by a seasonal cycle in the counts. Counts of foxes during surveys in June were correlated with total precipitation during the previous rainfall season, but not with concurrent counts of prey. Number of foxes seen/0.8-km interval was more highly correlated with estimated sighting distance based on physical features, such as hills and plains, than with current vegetation density or type. Mean number of foxes counted per survey per route ranged from two to 20. Counts of foxes increased over time on one route, decreased over time on another, and showed a curvilinear trend on two routes. The average number of foxes seen over all routes did not show any long-term trend. However, small samples, missing data, and lack of replication limited statistical analysis and interpretation of surveys. Statistical tests on simulated data similar to the data collected during the surveys indicated that larger samples, which could be obtained by replication, would be needed to detect changes in the population of foxes with any efficiency (statistical power). An expanded spotlight-survey program of kit foxes, with additional routes and replicated surveys, could be used to monitor population trends throughout the range of this endangered subspecies.

Sex allocation theory predicts that combined sexes are favored in sedentary and sessile organisms because localized gamete dispersal and local mate competition (LMC) among gametes promote decelerating fitness "gain curves" that relate male investment to reproductive success. Under this LMC model, males fertilize all locally available eggs at low sperm output, additional output leads to proportionally fewer fertilizations, and combined sexes with female-biased sex allocation are favored. Decelerating male gain curves have been found in hermaphroditic flowering plants, but the present paper reports the first analysis in an animal. The colonial hermaphroditic bryozoan Celleporella hyalina forms unisexual male and female zooids that can be counted to estimate absolute and relative gender allocations. I placed "sperm donor" colonies - each with different numbers of male zooids, and each homozygous for diagnostic allozyme alleles - among target maternal colonies on field mating arrays, and estimated donor fertilization success by scoring allozyme markers in target-colony progeny. Fertilization success increased with numbers of donor male zooids, but linear and not decelerating curves fit the data best. Mean sex allocation was not female biased, consistent with nondecelerating male gain. Sperm donors, moreover, did not monopolize matings as expected under high LMC, but rather shared paternity with rival colonies. Hence localized water-borne gamete dispersal alone may not yield decelerating male gain and favor the maintenance of hermaphroditism; relaxed sperm competition in low density populations might also be required. In free-spawning marine organisms, males cannot control access to fertilizations, intense sperm competition may be commonplace, and high male sex allocation may be selected to enhance siring success under competition.

Working under the authorities of the Magnuson Act, the Marine Mammal Protection Act, the Endangered Species Act, and the Lacey Act, 112 federal enforcement agents monitor fishery practices along the coastlines of the nation. The work is often dangerous, because of the vagaries of the sea, and the potential for criminal violence.

AN - 78835442; 9048443 AB - Why some species exhibit remarkable variation among populations while closely related species are relatively uniform remains unclear. The strawberry dart-poison frog (Dendrobates pumillo) exhibits spectacular color and pattern polmorphism among populations in the Bocas del Toro archipelago of Panama. In contrast, two other sympatric species of dart-poison frog, Phyllobates lugubris and Minyobates sp., show little color or pattern variation among island populations. Here we demonstrate that the color and pattern variation among populations of D. pumilio is not matched by higher levels of mitochondrial DNA sequence divergence relative to P. lugubris or Minyobates sp. Thus, neutral divergence in allopatry is unlikely to have caused the geographical differences observed in D. pumilio. We suggest that strong sexual selection associated with female parental care in D. pumilio, which contrasts the male parental care of P. lugubris and Minyobates sp., may have driven divergence in coloration and pattern in D. pumilio.

AN - 62450080; ED426857 AB - This book presents the National Science Resources Center's (NSRC's) strategic planning model for bringing about district-wide elementary science reform in accordance with the National Science Education Standards. The NSRC model views the elementary science program as a cohesive system that includes: a research-based, inquiry-centered science curriculum; professional development; materials support; appropriate assessment strategies; and community and administrative support. The system can be modified to meet the needs of large, small, urban, or rural school districts. Part One of this book, "Building a Foundation for Change," explains the rationale for inquiry-centered science and provides some basic tools for planning such a program. Part Two, "The Nuts and Bolts of Change," explains how to implement an inquiry-centered science program by focusing on the five elements of the NSRC model for science education reform. Part Three, "Inquiry-Centered Science in Practice," is a collection of eight case studies of efforts to implement the NSRC model. Appendices contain a list of professional associations and government agencies involved in science education reform and exemplary elementary science curriculum materials.

Though these species differ in ecology, spacing behavior, & taxonomy, they all form complex social relationships with long-term associations among well-acquainted individuals. Evidence is presented that indicates that they share songs when song-matching during counter-singing at territorial boundaries & when proclaiming group membership. However, collaborative vocal learning will evolve differently given different types of social interactions, particularly whether they are aggressive territorial interactions or collaborative. The sharing of vocalizations is shown to be non-sex-specific, as both male & female birds evidence this trait. 10 Figures, 178 References. D. M.

This event is inferred from a marine-to-continental series of carbonate and siliciclastic rocks that record the end of Messinian marine deposition in the Melilla Basin and presumably marks the final isolation of the Paleo-Mediterranean Sea. The evidence from the Melilla Basin is approximately coeval with an increase in benthic foraminiferal delta (super 18) O values from a deep-marine section in the Bou Regreg valley, NW Morocco (Hodell et al., 1994). This increase suggests that a glacio-eustatic lowering of sea level, at least, contributed to the final closure of the Mediterranean during the Messinian Salinity Crisis. The marine-to-continental succession onlaps a carbonate complex that contains evidence for multiple relative sea-level changes leading up to the main drawdown. From bottom to top, the carbonate complex is composed of: (1) an onlapping ramp; (2) a prograding bioclastic platform; (3) a prograding and, locally, downstepping Porites-reef complex; and (4) a topography-draping sequence composed of grainstones, Porites reefs, and stromatolites (terminal carbonate complex of Esteban, 1979). The transgressive ramp correlates to relatively low values of benthic foraminiferal delta (super 18) O values from a Tortonian-to-lower Messinian section at Bou Regreg (Hodell et al., 1994). This correlation indicates, at least in part, a link between rising sea level and a reduction in global ice volume during deposition of the ramp. A major fall in relative sea level ( approximately 60 m) occurred near the demise of the reef complex during chron C3n.1n at 5.95+ or -0.10 Ma. This signals the initiation of drawdown and changing environmental conditions in the Melilla Basin (a marginal basin), and perhaps the entire Paleo-Mediterranean Sea. A megabreccia interpreted as forming by solution collapse of evaporites on the basin margin of the reef complex occurs at the base of the terminal carbonate complex. Updip, a major subaerial unconformity separates the reef complex and terminal carbonate complex. Evaporite deposition likely occurred during this exposure event and has been dated at 5.82+ or -0.02 Ma near the base of chron C3r. We contend that these evaporites, restricted to the shallow Melilla Basin, are related to the continuation of the initial stage of the major drawdown of the Paleo-Mediterranean Sea.

Two floodplain sites were compared: one forested and the other vegetated by grass. At both sites, the soil layer through which the groundwater moved was very sandy. The nitrate concentrations leaving the crop fields were 20-30 mg N 1 (super -1) and averaged 25 mg N 1 (super -1) . Nitrate concentrations declined about 32% on average from the field edge to 48 m into the forest and this decrease was about 44% on average in the grassed buffer. These decreases were greater in the winter than in the summer. Nitrate to chloride ratios declined about 43% across the riparian forest transect. Declines in nitrate concentration were not accompanied by offsetting increases in dissolved organic N or ammonium. Soil E (sub h) averaged 191 mV and 263 mV at 33 m and 48 m into the forest, respectively. While nitrate removal rates were the highest of three study sites we have investigated in the Maryland Coastal Plain, nitrate concentrations entering the stream channel were still high (12-18 mg N 1 (super -1) ). The flux of nitrate in groundwater from the farm fields at this site clearly exceeded the nitrate removal capacity of these riparian buffers.

It attempts to describe, catalogue and classify all minerals known and recognized up to the end of 1995, but in a considerably less detailed format than that used for the 7th edition. The first entry for each mineral is the Dana classification number (the silicates being so numbered for the first time: e.g. pumpellyite-(Fe (super 2+) ) is 58.2.2.5); this is followed by the name and its derivation, chemical formula, polytypes etc., crystallography, physical and optical properties, range of chemical substitutions and phase relationships, type of occurrence and a selection of the better known localities. References are given in an abbreviated form: e.g. AM 32:1130(1960). There is an appendix giving new minerals for 1996 and three indexes (mineral names in [Dana] numerical order, mineral names in alphabetical order and a general index of mineral and group names).

She is well-versed in the habits of wildlife in the Vermont mountains, and leads groups on wilderness treks to study tracks, observe habitat characteristics, and identify other signs of wildlife passage, such as chewed grass, droppings, marked trees, and turned stones. Morse studied literature in college, and often approaches tracking from the development of a story line. She has studied with important naturalists and worked in a wide variety of habitats. Ultimately, detailed tracking data can be used to develop the resource inventories used by land management and wildlife management agencies.

The various catchments were characterized by different proportions of cropland; annual flow-weighted mean concentrations of nitrate-nitrogen and organic combined nitrogen and carbonaceous organic matter in the surface waters correlated with the relative amounts of base flow and stormwater flow. As the proportion of base flow increased, the concentration of nitrate increased and those of organic nitrogen and carbon decreased. This behaviour suggested that discharge of nitrate was associated with groundwater flow while discharges of organic nitrogen and carbon were controlled by surface runoff. Concentrations of different species of combined nitrogen also increased as the proportion of cropland within the catchment increased. A statistical model was devised with the ability to predict the concentration of different species of combined nitrogen from the 2 variables consisting of the proportions of cropland and the baseflow. By contrast, the total-phosphorus concentration was not correlated with cropland or baseflow ratios but was correlated with the concentrations of suspended solids, which differed between catchments.
