TY - JOUR T1 - Are soils of Iowa USA currently a carbon sink or source? Simulated changes in SOC stock from 1972 to 2007 AN - 1777168711; 14363507 AB - Upscaling the spatial and temporal changes in carbon (C) stocks and fluxes from sites to regions is a critical and challenging step toward improving our understanding of the dynamics of C sources and sinks over large areas. This study simulated soil organic C (SOC) dynamics within 0-100cm depth of soils across the state of Iowa in the USA from 1972 to 2007 using the General Ensemble biogeochemical Modeling System (GEMS). The model outputs with variation coefficient were analyzed and assembled from simulation unit to the state scale based upon major land use types at annual step. Results from this study indicate that soils (within a depth of 0-100cm) in Iowa had been a SOC source at a rate of 190 plus or minus 380kg Cha super(-1)yr super(-1). This was likely caused by the installation of a massive drainage system which led to the release of SOC from deep soil layers previously protected under poor drainage conditions. The annual crop rotation was another major force driving SOC variation and resulted in spatial variability of annual budgets in all croplands. Annual rate of change of SOC stocks in all land types depended significantly on the baseline SOC levels; soils with higher SOC levels tended to be C sources, and those with lower levels tended to be C sinks. Management practices (e.g., conservation tillage and residue management practices) slowed down the C emissions from Iowa soils, but could not reverse the general trend of net SOC loss in view of the entire state due mainly to a high level of baseline SOC stocks.

Passive and active cloud-water collectors, throughfall and stemflow collectors, visibility or droplet size measurements, and micrometeorological sensors are typically used to measure the fog water inputs to ecosystems. In addition, stable isotopes may be used as a natural tracer for fog and rain. Previous studies have shown that the isotopic signature of fog tends to be more enriched in the heavier isotopes 2H and 18O than that of rain, due to differences in condensation temperature and history. Differences between fog and rain isotopes are largest when rain is from synoptic-scale storms, and fog or orographic cloud water is generated locally. Smaller isotopic differences have been observed between rain and fog on mountains with orographic clouds, but only a few studies have been conducted. Quantifying fog deposition using isotope methods is more difficult in forests receiving mixed precipitation, because of limitations in the ability of sampling equipment to separate fog from rain, and because fog and rain may, under some conditions, have similar isotopic composition. This article describes the various types of fog most relevant to montane cloud forests and the importance of fog water deposition in the hydrologic budget. A brief overview of isotope hydrology provides the background needed to understand isotope applications in cloud forests. A summary of previous work explains isotopic differences between rain and fog in different environments, and how monitoring the isotopic signature of surface water, soil water and tree xylem water can yield estimates of the contribution of fog water to streamflow, groundwater recharge and transpiration. Next, instrumentation to measure fog and rain, and methods to determine isotopic concentrations in plant and soil water are discussed. The article concludes with the identification of some of the more pressing research questions in this field and offers various suggestions for future research.

Seven subspecies occur in varied habitats and elevations from India and Sri Lanka throughout southeastern Asia. Body mass and antler length decrease from west to east. R. unicolor is considered ancestral relative to the form of its male-only antlers and social behavior. Populations are vulnerable because of overexploitation for subsistence and markets in meat and antlers. R. unicolor was elevated by the International Union for Conservation of Nature and Natural Resources from no status in 2006 to ""Vulnerable"" in 2008 because of >50%% decline in many populations over the past 3 generations. It is well represented in zoos and private collections and is introduced in Australia, New Zealand, South Africa, and the United States.

AN - 851751525; 21261983 AB - A realistic estimation of the health risk of human exposure to solid-phase arsenic (As) derived from historic mining operations is a major challenge to redevelopment of California's famed "Mother Lode" region. Arsenic, a known carcinogen, occurs in multiple solid forms that vary in bioaccessibility. X-ray absorption fine-structure spectroscopy (XAFS) was used to identify and quantify the forms of As in mine wastes and biogenic solids at the Lava Cap Mine Superfund (LCMS) site, a historic "Mother Lode" gold mine. Principal component analysis (PCA) was used to assess variance within water chemistry, solids chemistry, and XAFS spectral datasets. Linear combination, least-squares fits constrained in part by PCA results were then used to quantify arsenic speciation in XAFS spectra of tailings and biogenic solids. The highest dissolved arsenic concentrations were found in Lost Lake porewater and in a groundwater-fed pond in the tailings deposition area. Iron, dissolved oxygen, alkalinity, specific conductivity, and As were the major variables in the water chemistry PCA. Arsenic was, on average, 14 times more concentrated in biologically-produced iron (hydr)oxide than in mine tailings. Phosphorous, manganese, calcium, aluminum, and As were the major variables in the solids chemistry PCA. Linear combination fits to XAFS spectra indicate that arsenopyrite (FeAsS), the dominant form of As in ore material, remains abundant (average: 65%) in minimally-weathered ore samples and water-saturated tailings at the bottom of Lost Lake. However, tailings that underwent drying and wetting cycles contain an average of only 30% arsenopyrite. The predominant products of arsenopyrite weathering were identified by XAFS to be As-bearing Fe (hydr)oxide and arseniosiderite (Ca2Fe(AsO4)3O3•3H2O). Existence of the former species is not in question, but the presence of the latter species was not confirmed by additional measurements, so its identification is less certain. The linear combination, least-squares fits totals of several samples deviate by more than ± 20% from 100%, suggesting that additional phases may be present that were not identified or evaluated in this study. Sub- to anoxic conditions minimize dissolution of arsenopyrite at the LCMS site, but may accelerate the dissolution of As-bearing secondary iron phases such as Fe3+-oxyhydroxides and arseniosiderite, if sufficient organic matter is present to spur anaerobic microbial activity. Oxidizing, dry conditions favor the stabilization of secondary phases, while promoting oxidative breakdown of the primary sulfides. The stability of both primary and secondary As phases is likely to be at a minimum under cyclic wet-dry conditions. Biogenic iron (hydr)oxide flocs can sequester significant amounts of arsenic; this property may be useful for treatment of perpetual sources of As such as mine adit water, but the fate of As associated with natural accumulations of floc material needs to be assessed.

Unsaturated-zone processes, including preferential flow, play a major role in these effects but are not well understood. In the Bogue Phalia basin, an intensely agricultural area in the Delta region of northwestern Mississippi, the fine-textured soils often exhibit surface ponding and runoff after irrigation and rainfall as well as extensive surface cracking during prolonged dry periods. Fields are typically land-formed to promote surface flow into drainage ditches and streams that feed into larger river ecosystems. Downward flow of water below the root zone is considered minimal; regional groundwater models predict only 5% or less of precipitation recharges the heavily used alluvial aquifer. In this study transport mechanisms within and below the root zone of a fallow soybean field were assessed by performing a 2-m ring infiltration test with tracers and subsurface monitoring instruments. Seven months after tracer application, 48 continuous cores were collected for tracer extraction to define the extent of water movement and quantify preferential flow using a mass-balance approach. Vertical water movement was rapid below the pond indicating the importance of vertical preferential flow paths in the shallow unsaturated zone, especially to depths where agricultural disturbance occurs. Lateral flow of water at shallow depths was extensive and spatially non-uniform, reaching up to 10m from the pond within 2months. Within 1month, the wetting front reached a textural boundary at 4-5m between the fine-textured soil and sandy alluvium, now a potential capillary barrier which, prior to extensive irrigation withdrawals, was below the water table. Within 10weeks, tracer was detectable at the water table which is presently about 12m below land surface. Results indicate that 43% of percolation may be through preferential flow paths and that any water breaking through the capillary barrier (as potential recharge) likely does so in fingers which are difficult to detect with coring methods. In other areas where water levels have declined and soils have similar properties, the potential for transport of agricultural chemicals to the aquifer may be greater than previously assumed.

Here we develop a Monte Carlo approach for estimating the distribution of geologically reasonable fault-slip histories that fit the offset and age data from a population of dated and displaced landforms. The model assumes that the landforms share common faulting histories, the offset and age constraints are correct, and the fault has not reversed shear sense. Analysis of the model results yields both a precise average slip rate, in the case where a linear fit is applied to the data, and a best-fit fault-slip history, in the case where the linear constraint is removed. The method can be used to test for secular variation in slip because the uncertainty on this best-fit history is quantified. By applying the method to previously published morphochronologic data from faulted late Quaternary terrace risers along the Kunlun fault in China and the Awatere fault in New Zealand, we have assessed the extent to which our modeled average slip rates match previously reported values and the data support previous interpretations of uniform slip rate. The Kunlun data set yields average slip rates of 8.7+3.6/2.1mm/yr and 5.1+1.6/1.2mm/yr (68.27% confidence), for the central and eastern reaches of the fault, respectively, both of which match previously published slip rates. Our analysis further indicates that these fault reaches have both slipped uniformly over the latest Quaternary. In contrast, analysis of data from the Saxton River site along the Awatere fault reveals a mid-Holocene deceleration in slip rate from 6.2+1.6/1.4mm/yr to 2.8+1.0/0.6mm/yr. This result contradicts previous interpretations of uniform slip along the Awatere fault. The Monte Carlo method we present here for quantifying fault-slip histories using the offset and age data from a population of faulted landforms provides an important tool for distinguishing temporally uniform from secularly varying fault slip.

Goldwater Range-West AN - 959104128; 2012-035784 AB - Marine Corps Air Station Yuma manages the Barry M. Goldwater Range-West, which encompasses approximately 2,800 square kilometers of Sonoran Desert habitat in southwestern Arizona. The Barry M. Goldwater Range is a major U.S. military installation designed as an air combat training location for the U.S. Marine Corps and U.S. Air Force, but it also includes some of the most pristine desert habitat in the United States. In an effort to ensure the long-term viability of this unique natural resource, the U.S. Geological Survey (USGS) has developed an Integrated Natural Resources Management Plan and Inventory and Monitoring Plan to guide natural resource management of the Barry M. Goldwater Range-West. This Inventory and Monitoring Plan provides a framework for long-term ecosystem monitoring on Barry M. Goldwater Range-West lands by identifying existing and potential threats to ecosystem function, prioritizing resources for monitoring, and providing information and protocols necessary to initiate a long-term ecosystem monitoring program. The Inventory and Monitoring Plan and related protocols were developed through extensive review of existing Sonoran Desert monitoring programs and monitoring literature and through a 2-day workshop with resource managers, monitoring experts, and other stakeholders. The Barry M. Goldwater Range-West Inventory and Monitoring Plan stresses the importance of regional monitoring partnerships and protocol standardization for understanding landscape-scale ecosystem changes in the Sonoran Desert; information and protocols contained within the plan may also be of interest to land managers engaged in large-scale ecosystem monitoring and adaptive management of other arid regions.

Washington, USA. Eelgrass blade length exceeded 1 m. Velocity profiles up to 1.5 m above the sea floor were collected over a spring-neap tidal cycle with a downward-looking pulse-coherent acoustic Doppler profiler above the canopies and two acoustic Doppler velocimeters within the canopies. The eeigrass attenuated currents by a minimum of 40%, and by more than 70% at the most densely vegetated site. Attenuation decreased with increasing current speed. The data were compared to the shear-layer model of vegetated flows and the displaced logarithmic model. Velocity profiles outside the meadows were logarithmic. Within the canopies, most profiles were consistent with the shear-layer model, with a logarithmic layer above the canopy. However, at the less-dense sites, when currents were strong, shear at the sea floor and above the canopy was significant relative to shear at the top of the canopy, and the velocity profiles more closely resembled those in a rough-wall boundary layer. Turbulence was strong at the canopy top and decreased with height. Friction velocity at the canopy top was 1.5-2 times greater than at the unvegetated, sandy site. The coefficient of drag C sub(D) on the overlying flow derived from the logarithmic velocity profile above the canopy, was 3-8 times greater than at the unvegetated site (0.01-0.023 vs. 2.9 x 10 super(-3)).

The effects of daylighting in coordination with visual comfort, on university library users were measured in relation to four environmental processes, namely privacy, personal space, territoriality, and crowding. It was found that daylight and four environmental processes are related. It is believed that the consideration of this relationship will encourage students to use their libraries fully as an essential component of university education and campus life.

Yet, the importance of free-living N sub(2) fixation--a process that occurs on a wide variety of substrates, is nearly ubiquitous in terrestrial ecosystems, and may often represent the dominant pathway for acquiring newly available N--is often underappreciated. Here, we draw from studies that investigate free-living N sub(2) fixation from functional, physiological, genetic, and ecological perspectives. We show that recent research and analytical advances have generated a wealth of new information that provides novel insight into the ecology of N sub(2) fixation as well as raises new questions and priorities for future work. These priorities include a need to better integrate free-living N sub(2) fixation into conceptual and analytical evaluations of the N cycle's role in a variety of global change scenarios.

The eels were sampled using leaf litter traps (N = 140) from 17 July to 28 August 2008. The captured (N = 15) Asian swamp eels ranged in total length from 4.9 cm to 12.2 cm, and were estimated to be from 21 to 51 days old (N = 13), and hatched from 13 June to 7 August 2008. Assuming linear growth, these individuals grew an average rate of 0.2 cm per day. To the authors' knowledge, this was the first time otoliths were used to estimate daily age, growth, and hatching date for M. albus, which can be useful for understanding the ecology of this species in the wild.

Actively growing forests are generally considered to be a major carbon sink, but forest wildfires lead to large releases of biomass carbon into the atmosphere. Aboveground forest biomass carbon (AFBC), an important ecological indicator, and fire-induced carbon emissions at regional scales are highly relevant to forest sustainable management and climate change. It is challenging to accurately estimate the spatial distribution of AFBC across large areas because of the spatial heterogeneity of forest cover types and canopy structure. In this study, Forest Inventory and Analysis (FIA) data, Landsat, and Landscape Fire and Resource Management Planning Tools Project (LANDFIRE) data were integrated in a regression tree model for estimating AFBC at a 30-m resolution in the Utah High Plateaus. AFBC were calculated from 225 FIA field plots and used as the dependent variable in the model. Of these plots, 10% were held out for model evaluation with stratified random sampling, and the other 90% were used as training data to develop the regression tree model. Independent variable layers included Landsat imagery and the derived spectral indicators, digital elevation model (DEM) data and derivatives, biophysical gradient data, existing vegetation cover type and vegetation structure. The cross-validation correlation coefficient (r value) was 0.81 for the training model. Independent validation using withheld plot data was similar with r value of 0.82. This validated regression tree model was applied to map AFBC in the Utah High Plateaus and then combined with burn severity information to estimate loss of AFBC in the Longston fire of Zion National Park in 2001. The final dataset represented 24 forest cover types for a 4 million ha forested area. We estimated a total of 353 Tg AFBC with an average of 87 MgC/ha in the Utah High Plateaus. We also estimated that 8054 Mg AFBC were released from 2.24 km2 burned forest area in the Longston fire. These results demonstrate that an AFBC spatial map and estimated biomass carbon consumption can readily be generated using existing database. The methodology provides a consistent, practical, and inexpensive way for estimating AFBC at 30-m resolution over large areas throughout the United States.

Land managers, research scientists, and resource specialists identified common concerns regarding the potential effects of climate change on public lands and natural resources in the Great Basin and Mojave Desert and developed recommendations for mitigation, adaptation, and research needs. Water and, conversely, the effects of drought emerged as a common theme in all breakout sessions on terrestrial and aquatic species at risk, managing across boundaries, monitoring, and ecosystem services. Climate change models for the southwestern deserts predict general warming and drying with increasing precipitation variability year to year. Scientists noted that under these changing conditions the past may no longer be a guide to the future in which managers envision increasing conflicts between human water uses and sustaining ecosystems. Increasing environmental stress also is expected as a consequence of shifting ecosystem boundaries and species distributions, expansion of non-native species, and decoupling of biotic mutualisms, leading to increasingly unstable biologic communities. Managers uniformly expressed a desire to work across management and agency boundaries at a landscape scale but conceded that conflicting agency missions and budgetary constraints often impede collaboration. More and better science is needed to cope with the effects of climate change but, perhaps even more important is the application of science to management issues using the methods of adaptive management based on long-term monitoring to assess the merits of management actions. Access to data is essential for science-based land management. Basic inventories, spatial databases, baseline condition assessments, data quality assurance, and data sharing were identified as top information priorities by all participants at this workshop. Optimizing the utility of ecosystem monitoring data will require standardizing monitoring protocols across agencies. Better communication among researchers and managers and cooperation through partnerships to manage resources across boundaries were emphasized as necessary for adapting to changing climatic conditions. However, even these strategies may be insufficient unless policy mandates, agency missions, and funding are coordinated at a high level.

We used an avian radar system to measure avian activity at Beale Air Force Base, California, USA, during 2008 and 2009. We conducted a 2-part analysis to examine relationships among avian activity, bird strikes, and meteorological and time-dependent factors. We found that avian activity around the airfield was greater at times when bird strikes occurred than on average using a permutation resampling technique. Second, we developed generalized linear mixed models of an avian activity index (AAI). Variation in AAI was first explained by seasons that were based on average migration dates of birds at the study area. We then modeled AAI by those seasons to further explain variation by meteorological factors and daily light levels within a 24-hour period. In general, avian activity increased with decreased temperature, wind, visibility, precipitation, and increased humidity and cloud cover. These effects differed by season. For example, during the spring bird migration period, most avian activity occurred before sunrise at twilight hours on clear days with low winds, whereas during fall migration, substantial activity occurred after sunrise, and birds generally were more active at lower temperatures. We report parameter estimates (i.e., constants and coefficients) averaged across models and a relatively simple calculation for safety officers and wildlife managers to predict AAI and the relative risk of bird strike based on time, date, and meteorological values. We validated model predictability and assessed model fit. These analyses will be useful for general inference of avian activity and risk assessment efforts. Further investigation and ongoing data collection will refine these inference models and improve our understanding of factors that influence avian activity, which is necessary to inform management decisions aimed at reducing risk of bird strikes.

Techniques that rely on dentition, horn, and facial patterns have limited utility for European mouflon sheep (Ovis gmelini musimon), but tooth cementum lines may offer a useful alternative. Cementum lines may not be reliable outside temperate regions, however, because lack of seasonality in diet may affect annulus formation. We evaluated the utility of tooth cementum lines for estimating age of mouflon in Hawai'i in comparison to dentition. Cementum lines were present in mouflon from Mauna Loa, island of Hawai'i, but were less distinct than in North American sheep. The two age-estimation methods provided similar estimates for individuals aged less than or equal to 3 yr by dentition (the maximum age estimable by dentition), with exact matches in 51% (18/35) of individuals, and an average difference of 0.8 yr (range 0-4). Estimates of age from cementum lines were higher than those from dentition in 40% (14/35) and lower in 9% (3/35) of individuals. Discrepancies in age estimates between techniques and between paired tooth samples estimated by cementum lines were related to certainty categories assigned by the clarity of cementum lines, reinforcing the importance of collecting a sufficient number of samples to compensate for samples of lower quality, which in our experience, comprised approximately 22% of teeth. Cementum lines appear to provide relatively accurate age estimates for mouflon in Hawai'i, allow estimating age beyond 3 yr, and they offer more precise estimates than tooth eruption patterns. After constructing an age distribution, we estimated annual survival with a log-linear model to be 0.596 (95% CI 0.554-0.642) for this heavily controlled population.

Pliometanastes (Megalonychidae) is the earliest ground sloth in New Mexico, with three Hemphillian records from the Chamita Formation in the Espanola basin in Rio Arriba County. Megalonyx (Megalonychidae) occurs in five Blancan and two Irvingtonian faunas in the Rio Grande Valley. Nothrotheriops (Nothrotheriidae) has been identified from 10 Rancholabrean cave sites, all but one of which are in the southern part of the state. Paramylodon (Mylodontidae) is known from four Blancan and five Rancholabrean faunas from throughout New Mexico. The type of ground sloth present in different faunas varies and reflects the differences in the timing of the first appearance of different groups in North America, evolutionary changes within lineages, and differences in the autecology between the different sloths. Consequently, only one type of sloth is usually found in a fauna, with the presence of more than one type of sloth being the exception and usually reflects unique ecological conditions.

AN - 904460592; 2011-102728 AB - Eosauropus is a distinctive tetrapod footprint ichnogenus found in the upper part of the Chinle Group and basal Wingate Sandstone in New Mexico, Colorado and Utah. Studies of the Triassic-Jurassic transition zone in the uppermost Chinle Group and basal Wingate Sandstone, in western Colorado and eastern Utah, reveal that trackways attributed to Eosauropus are particularly abundant. In most cases the tracks are deep, but poorly-preserved, indicating sandy substrates that were relatively highly saturated. At these sites the trackways are pes only, indicating overprinting or bipedal progression. Trackway configurations are nevertheless clear, and in some cases parallel, suggestive of gregarious behavior. We describe three previously unreported sites on the Colorado-Utah frontier that occur in a narrow stratigraphic zone, in the basal Wingate Sandstone, that can be traced to other localities in the area. The tracks are locally associated with other footprints that indicate a latest Triassic age for this zone in this region.

The tides off the Kalaupapa Peninsula are mixed semidiurnal. The wave climate is dominated by two end-members: large northwest Pacific winter swell that directly impacts the study site, and smaller, shorter-period northeast trade-wind waves that have to refract around the peninsula, resulting in a more northerly direction before propagating over the study site. The currents primarily are alongshore and are faster at the surface than close to the seabed; large wave events, however, tend to drive flow in a more cross-shore orientation. The tidal currents flood to the north and ebb to the south. The waters off the peninsula appear to be a mix of cooler, more saline, deeper oceanic waters and shallow, warmer, lower-salinity nearshore waters, with intermittent injections of freshwater, generally during the winters. Overall, the turbidity levels were low, except during large wave events. The low overall turbidity levels and rapid return to pre-event background levels following the cessation of forcing suggest that there is little fine-grained material. Large wave events likely inhibit the settlement of fine-grained sediment at the site. A number of phenomena were observed that indicate the complexity of coastal circulation and water-column properties in the area and may help scientists and resource managers to better understand the implications of the processes on marine ecosystem health.

Previous similar approaches typically have assumed that the extreme-value samples identified by PCA represent end members. The method presented herein is different from previous work in that (1) end members were not assumed to have been sampled but rather were estimated and constrained by prior knowledge; (2) end-member mixing was quantified in relation to hydrogeologic domains, which focuses model results on major hydrologic processes; (3) a method to select an appropriate number of end members using a series of cluster analyses is presented; and (4) conservative tracers were weighted preferentially in model calibration, which distributed model errors of optimized values, or residuals, more appropriately than would otherwise be the case. The latter item also provides an estimate of the relative influence of geochemical evolution along flow paths in comparison to mixing. This method was applied to groundwater in Wind Cave and the associated karst aquifer in the Black Hills of South Dakota, USA. The end-member mixing model was used to test a hypothesis that five different end-member waters are mixed in the groundwater system comprising five hydrogeologic domains. The model estimated that Wind Cave received most of its groundwater inflow from local surface recharge with an additional 33% from an upgradient aquifer.

We captured 1996 bats of 15 species in mist nets set over water during 120 nights of sampling and recorded echolocation calls of an additional species. The bat fauna at Mesa Verde included every species of bat known west of the Great Plains in Colorado, except the little brown bat (Myotis lucifugus). Some species showed skewed sex ratios, primarily due to a preponderance of males. Thirteen species of bats reproduced at Mesa Verde. Major differences in spring precipitation between the 2 years of our study were associated with differences in reproductive rates and, in some species, with numbers of juveniles captured. Reduced reproductive effort during spring drought will have a greater impact on bat populations with the forecasted increase in aridity in much of western North America by models of global climate change. We radiotracked 46 bats of 5 species to roosts and describe the first-known maternity colonies of spotted bats (Euderma maculatum) in Colorado. All 5 species that we tracked to diurnal roosts relied almost exclusively on rock crevices rather than trees or snags, despite the presence of mature forests at Mesa Verde and the use of trees for roosts in similar forests elsewhere by some of these species. Comparisons with past bat surveys at Mesa Verde and in surrounding areas suggest no dramatic evidence for effects of recent stand-replacing fires on the composition of the bat community.

There are few or no losses in hoop or fyke traps set where turtles may reach air, including placement in shallows, addition of floats on traps, and tying traps securely to a stake or to shore. Turtle mortality occurs when traps are set deep, traps are checked at intervals > 1 day, and when turtles are captured as bycatch. Devices are available that exclude turtles from traps set for crab or game fish harvest. Slotted gates in front of the trap mouth reduce turtle entry, but small individuals still may be trapped. Incidental take of turtles is preventable by integrating several designs into aquatic traps, such as adding floats to the top of traps so turtles may reach air or an extension tube (chimney, ramp) that creates an escape route.

We also hypothesized that the probability of colonization relates to land use, wetland size, or riparian forest. In a 5-yr study, we found no support for an effect of non-native species on northern red-legged frogs. Instead, probability of local extinction decreased with the extent of emergent vegetation and riparian forest. This finding suggests that managers consider the role of habitat when confronting non-native species problems.

They expand, contract, and migrate across the bottom of valleys in response to changing flow and vegetation. Channel dynamics fundamentally structure river and floodplain ecosystems. Human activities that affect channel migration----including river regulation, channel revetments, and land use----have the potential for impacting river ecosystems. Active channel width and lateral movement of the active channel centerline was analyzed in 17 km valley segment of the middle Green River in western Washington from aerial photographs for 26 years of unregulated flows (1936--1961) and 41 years of flood regulation by Howard Hansen Dam. Area-based measures proved more robust for characterizing channel dynamics than cross-sectional measurements, though cross-sectional measurements are useful for resolving local processes. Prior to regulation from 1936 to 1961, the active channel width varied from 82 m to 120 m (median 94 m) and the channel migrated laterally a total of 68 m. After flood regulation from 1961 to 2002, the active channel width was generally smaller, varying from 84 m to 52 m (median 69 m) and the channel migrated 48 m. Streamflow greater than about 250 m3/s are most effective for forcing migration and have been reduced since dam construction. The river has re-occupied areas with increasing frequency since dam construction. High flows are essential to create new channel and floodplain habitats in the middle Green River, but land cover/use and revetments in the river corridor are also influential factors for maintaining channel dynamics.

Binding of prions to soil (micro)particles dramatically enhances peroral disease transmission relative to unbound prions, and it was hypothesized that micrometer-sized particles present in other consumed materials may affect prion disease transmission via the oral route of exposure. Small, insoluble particles are present in many substances, including soil, human foods, pharmaceuticals, and animal feeds. It is known that meat and bone meal (MBM), a feed additive believed responsible for the spread of bovine spongiform encephalopathy (BSE), contains particles smaller than 20 is a subset of m and that the pathogenic prion protein binds to MBM. The potentiation of disease transmission via the oral route by exposure to MBM or three micrometer-sized mineral feed additives was determined. Data showed that when the disease agent was bound to any of the tested materials, the penetrance of disease was increased compared to unbound prions. Our data suggest that in feed or other prion-contaminated substances consumed by animals or, potentially, humans, the addition of MBM or the presence of microparticles could heighten risks of prion disease acquisition.

Survey-wide trend estimates based on the hierarchical model were generally more precise than estimates from the earlier analysis. No consistent pattern of differences existed in the magnitude of trends between the analysis methods. Survey-wide trend estimates changed substantially for 15 species between route-regression and hierarchical-model analyses. We compared regional estimates for states, provinces, and Bird Conservation Regions; differences observed in these regional analyses are likely a consequence of the route-regression procedure's inadequate accommodation of temporal differences in survey effort. We used species-specific hierarchical-model results to estimate composite change for groups of birds associated with major habitats and migration types. Grassland, aridland, and eastern-forest-obligate bird species declined, whereas urban suburban species increased over the interval 1968-2008. No migration status group experienced significant changes, although Nearctic-Neotropical migrant species showed intervals of decline and permanent resident species increased almost 20% during the interval. Hierarchical-model results better portrayed patterns of population change over time than route-regression results. We recommend use of hierarchical models for BBS analyses.

There have been few previous studies of resource use and forage quality of wintering greater white-fronted geese in North America, and as a consequence there has been little empirical support for management practices pertaining to habitat conservation of this broadly distributed species. Observations of >2,500 flocks of geese and collections of foraging birds revealed seasonal and geographic variation in resource use reflective of changes in habitat availability, selection, and fluctuating physiological demands. Autumn migrants from Alaska arrived first in the Klamath Basin of California and southern Oregon, where they fed on barley, oats, wheat, and potatoes. Geese migrated from the Klamath Basin into the Central Valley of California in late autumn where they exploited agricultural crops rich in soluble carbohydrates, with geese in the Sacramento Valley feeding almost exclusively on rice and birds on the Sacramento----San Joaquin Delta primarily utilizing corn. White-fronted geese began their northward migration in late winter, and by early spring most had returned to the Klamath Basin where 37% of flocks were found in fields of new growth cultivated and ""wild grasses. Cereal grains and potatoes ingested by geese were low in protein (7--14%) and high in soluble nutrients (17--47% neutral detergent fiber [NDF]), ""whereas grasses were low in available energy (47--49% NDF) but high in protein (26--42%). Greater white-fronted geese are generalist herbivores and can exploit a variety of carbohydrate-rich cultivated crops, likely making these geese less susceptible to winter food shortages than prior to the agriculturalization of the North American landscape. However, agricultural landscapes can be extremely dynamic and may be less predictable in the long-term than the historic environments to which geese are adapted. Thus far greater white-fronted geese have proved resilient to changes in land cover in the Pacific Flyway and by altering their migration regime have even been able to adapt to changes in the availability of suitable forage crops.

We refined a technique that uses recently voided excreta on snow to assess protein status in wild caribou (Rangifer tarandus) in late winter. Our study was the first application of this non-invasive, isotopic approach to assess protein status of wild caribou by determining dietary and endogenous contributions of nitrogen (N) to urinary urea. We used isotopic ratios of N ( delta delta 15N) in urine and fecal samples to estimate the proportion of urea N derived from body N (p-UN) in pregnant, adult females of the Chisana Herd, a small population that ranged across the Alaska-Yukon border. We took advantage of a predator-exclosure project to examine N status of penned caribou in April 2006. Lichens were the primary forage (>40%) consumed by caribou in the pen and delta delta 15N of fiber tracked the major forages in their diets. The delta delta 15N of urinary urea for females in the pen was depleted relative (-1.3 plus or minus plus or minus 1.0 parts per thousand [pptppt], plus or minus plus or minus SD) to the delta delta 15N of body N (2.7 plus or minus plus or minus 0.7pptppt). A similar proportion of animals in the exclosure lost core body mass (excluding estimates of fetal and uterine tissues; 55%) and body protein (estimated by isotope ratios; 54%). This noninvasive technique could be applied at various spatial and temporal scales to assess trends in protein status of free-ranging populations of northern ungulates. Intra- and inter-annual estimates of protein status could help managers monitor effects of foraging conditions on nutritional constraints in ungulates, increase the efficiency and efficacy of management actions, and help prepare stakeholders for potential changes in population trends.

To better understand effects of chronic wasting disease (CWD) and cougar (Puma concolor) predation, we studied mortality and recruitment of elk (Cervus elaphus) at Wind Cave National Park (WICA) during 2005--2009. We marked 202 elk (83 subadult M and 119 subadult and ad F) with Global Positioning System (GPS) collars, observed 28 deaths during 74,220 days of monitoring, and investigated 42 additional deaths of unmarked elk found dead. Survival rates were similar for males and females and averaged 0.863 (SE = 0.025) annually. Leading causes of mortality included hunting (0.065, SE = 0.019), CWD (0.034, SE = 0.012), and cougar predation (0.029, SE = 0.012). Marked elk killed by hunters and cougars typically were in good physical condition and not infected with CWD. Effects of mortality on population growth were exacerbated by low rates of pregnancy (subadults = 9.5%, SE = 6.6%; ad = 76.9%, SE = 4.2%) and perinatal survival (0.49, SE = 0.085 from 1 Feb to 1 Sep). Chronic wasting disease, increased predation, and reduced recruitment reduced the rate of increase for elk at WICA to approximately lambda lambda = 1.00 (SE = 0.027) during the past decade. Lower rates of increase are mitigating effects of elk on park vegetation, other wildlife, and neighboring lands and will facilitate population control, but may reduce opportunities for elk hunting outside the park.

In geese, recruitment is strongly affected by habitat conditions experienced by broods because gosling growth rates are indicative of forage conditions during brood rearing and strongly influence future survival and productivity. In 2006--2008, we studied gosling growth at 3 of the 4 major colonies on the YukonKuskokwim Delta, Alaska. Estimates of age-adjusted gosling mass at the 2 southern colonies (approx. 30% of the world population of breeding black brack) was low (gosling mass at 30.5 days ranged 346.7 plus or minus plus or minus 42.5 g to 627.1 plus or minus plus or minus 15.9 g) in comparison to a third colony (gosling mass at 30.5 days ranged 640.0 plus or minus plus or minus 8.3 g to 821.6 plus or minus plus or minus 13.6 g) and to most previous estimates of age-adjusted mass of brant goslings. Thus, our results are consistent with the hypothesis that poor gosling growth is negatively influencing the brant population. There are 2 non-mutually exclusive explanations for the apparent growth rates we observed. First, the population decline may have been caused by density-independent factors and habitat capacity has declined along with the population as a consequence of the unique foraging feedback between brant and their grazing habitats. Alternatively, a reduction in habitat capacity, as a result of changes to the grazing system, may have negatively influenced gosling growth, which is contributing to the overall long-term population decline. We found support for both explanations. For colonies over habitat capacity we recommend management to enhance foraging habitat, whereas for colonies below habitat capacity we recommend management to increase nesting productivity.

In this study physiological readiness to spawn in shovelnose sturgeon was examined to define more closely when spawning could occur and thus identify and evaluate prevailing environmental conditions that could cue spawning during that period. Reproductive assessments of Lower Missouri River shovelnose during 4 years (2005-2008) and at two locations (Gavins Point Dam, South Dakota and Boonville, Missouri) were used to identify shovelnose sturgeon spawning periods. Initiation of the spawning period, as defined by the presence of reproductively ready fish, was a highly predictable yearly event and extended over several weeks at each reach. The spawning period occurred earlier in the lower reach than in the upper reach and environmental conditions during the periods varied between locations and among years. Shovelnose sturgeon collected during the presumed spawning periods were at varying degrees of readiness to spawn as indicated by oocyte polarization index and blood reproductive hormones. Evaluation of the influence of environmental factors on readiness to spawn using stepwise multiple regression analysis indicated photoperiod followed by temperature were the best candidate variables overall to explain the trend. However, within geographically distinct populations gravid females are not all reproductively synchronized. Assuming that this apparent asynchrony in readiness is normal and not an artifact of the disturbed Missouri River system, we infer that individual sturgeon can persist in a reproductively ready state until conditions appropriate for spawning occur. Taken together, our results lead us to hypothesize that gravid females early in the reproductive cycle (post-vitellogenesis) respond to day length, a reliable annual cue, become increasingly more ready to spawn in response to temperature, and that another set of cues, short-term and specific for localized environmental conditions or events, serve to signal ovulation and release of gametes.

From 2004 to 2007, over 300 gravid female shovelnose sturgeon (Scaphirhynchus platorynchus) from the Lower Missouri River, that were expected to spawn in the year they were collected, were surgically implanted with transmitters and archival DSTs. Functional cluster modeling of telemetry data from the spawning season suggested two common migration patterns of gravid female shovelnose sturgeon. Fish implanted from 958 to 1181 river kilometer (rkm) from the mouth of the Missouri River (or northern portion of the Lower Missouri River within 354 rkm of the lowest Missouri River dam at rkm 1305) had one migration pattern. Of fish implanted from 209 to 402 rkm from the mouth of the Missouri River (or southern portion of the Lower Missouri River), half demonstrated a movement pattern similar to the northern fish while the other half demonstrated a migration pattern that covered more of the river. There was no apparent difference in migration patterns between successful and unsuccessful spawners. Multiple hypotheses exist to explain differences in migratory patterns among fish from different river reaches. Additional work is required to determine if observed differences are due to multiple adapted strategies, environmental alteration, and/or initial tagging date. Hierarchical Bayesian modeling of DST data indicated that variation in depth usage patterns was consistently different between successful and unsuccessful spawners, as indicated by differences in likelihood of switching between high and low variability states. Analyses of DST data, and data collected at capture, were sufficient to predict 8 of 10 non-spawners/incomplete spawners and all 30 spawners in the absence of telemetry location data. Together, the results of these two separate analyses suggest that caution is necessary in extrapolating spawning success from broad-scale movement data alone. More direct measures of spawning success may be necessary to precisely determine spawning success and to evaluate the effects of management actions.

The power analysis of PSPAP presented here was conducted to guide sampling design and effort decisions. The PSPAP sampling design has a nested structure with multiple gear subsamples within a river bend. Power analyses were based on a normal linear mixed model, using a mixed cell means approach, with variance estimates from the original data. It was found that, at current effort levels, at least 20 years for pallid and 10 years for shovelnose sturgeon is needed to detect a 5% annual decline. Modified bootstrap simulations suggest power estimates from the original data are conservative due to excessive zero fish counts. In general, the approach presented is applicable to a wide array of animal monitoring programs.

These changes have been implicated in the decline of the pallid sturgeon (Scaphirhynchus albus), which has been listed as a United States federal endangered species. The sympatric shovelnose sturgeon (S. platorynchus) is more common and widespread but has also been in decline. The decline of pallid sturgeon is considered symptomatic of poor reproductive success and low or no recruitment. In order to organize information about these species and provide a basis for future development of a predictive model to help guide recovery efforts, we present an expert-vetted, conceptual life-history framework that incorporates the factors that affect reproduction, growth, and survival of shovelnose and pallid sturgeons.

We used data collected during 11 nights of mark-recapture sampling on Aguiguan, Mariana Islands, to estimate introduced kiore (Rattus exulans Peale) density and detection probability, and evaluated factors affecting detectability to help inform possible eradication efforts. Modelling of 62 captures of 48 individuals resulted in a model-averaged density estimate of 55 kiore/ha. Kiore detection probability was best explained by a model allowing neophobia to diminish linearly (i.e. capture probability increased linearly) until occasion 7, with additive effects of sex and cumulative rainfall over the prior 48 hours. Detection probability increased with increasing rainfall and females were up to three times more likely than males to be trapped. In this paper, we illustrate the type of information that can be obtained by modelling mark-recapture data collected during pre-eradication monitoring and discuss the potential of using these data to inform eradication and post-eradication monitoring efforts.

Domestic architecture is investigated since housing is the most energy demanding building type. The study aims to demonstrate that the architectural subtleties developed between different house types have direct relevance to the different environmental parameters involved. It investigates two case study houses, one in the ancient city of Olynthus in northern Greece and one in the ancient city of Priene in southern Greece. The methodology is based on bibliographical comparative analysis between the two case study areas and observation. The study showed that at a historical time when housing was designed with consideration to the environment, two, different in many ways, housing types sensitive to their local climate were developed. The paper argues for the first time that the latter is the outcome of climatic differentiation.

As climate rapidly warmed similar to 11 700 years ago, the range of Joshua tree contracted, leaving only the populations near what had been its northernmost limit. Its ability to spread northward into new suitable habitats after this time may have been inhibited by the somewhat earlier extinction of megafaunal dispersers, especially the Shasta ground sloth. We applied a model of climate suitability for Joshua tree, developed from its 20th-century range and climates, to future climates modeled through a set of six individual general circulation models (GCM) and one suite of 22 models for the late 21st century. All distribution data, observed climate data, and future GCM results were scaled to spatial grids of similar to 1 km and similar to 4 km in order to facilitate application within this topographically complex region. All of the models project the future elimination of Joshua tree throughout most of the southern portions of its current range. Although estimates of future monthly precipitation differ between the models, these changes are outweighed by large increases in temperature common to all the models. Only a few populations within the current range are predicted to be sustainable. Several models project significant potential future expansion into new areas beyond the current range, but the species' historical and current rates of dispersal would seem to prevent natural expansion into these new areas. Several areas are predicted to be potential sites for relocation/assisted migration. This project demonstrates how information from paleoecology and modern ecology can be integrated in order to understand ongoing processes and future distributions.

To apply a relevant response to the potential consequences associated with invasions (e.g., emphasize management efforts to prevent new colonization or to eradicate the species in places where it has already settled), it is essential to understand invasion mechanisms and dynamics. Quantifying and understanding what influences rates of spatial spread is a key research area for invasion theory. In this paper, we develop a model to account for occupancy dynamics of an invasive species. Our model extends existing models to accommodate several elements of invasive processes; we chose the framework of hierarchical modeling to assess site occupancy status during an invasion. First, we explicitly accounted for spatial structure and how distance among sites and position relative to one another affect the invasion spread. In particular, we accounted for the possibility of directional propagation and provided a way of estimating the direction of this possible spread. Second, we considered the influence of local density on site occupancy. Third, we decided to split the colonization process into two subprocesses, initial colonization and recolonization, which may be ground-breaking because these subprocesses may exhibit different relationships with environmental variations (such as density variation) or colonization history (e.g., initial colonization might facilitate further colonization events). Finally, our model incorporates imperfection in detection, which might be a source of substantial bias in estimating population parameters. We focused on the case of the Eurasian Collared-Dove (Streptopelia decaocto) and its invasion of the United States since its introduction in the early 1980s, using data from the North American BBS (Breeding Bird Survey). The Eurasian Collared-Dove is one of the most successful invasive species, at least among terrestrial vertebrates. Our model provided estimation of the spread direction consistent with empirical observations. Site persistence probability exhibits a quadratic response to density. We also succeeded at detecting differences in the relationship between density and initial colonization vs. recolonization probabilities. We provide a map of sites that may be colonized in the future as an example of possible practical application of our work.

AN - 864958568; 14690727 AB - S. Creel et al. reported a negative correlation between fecal progesterone concentrations and elk: wolf ratios in greater Yellowstone elk (Cervus elaphus) herds and interpreted this correlation as evidence that pregnancy rates of elk decreased substantially in the presence of wolves (Cants lupus). Apparently, the hypothesized mechanism is that decreased forage intake reduces body condition and either results in elk failing to conceive during the autumn rut or elk losing the fetus during winter. We tested this hypothesis by comparing age-specific body condition (percentage ingesta-free body fat) and pregnancy rates for northern Yellowstone elk, one of the herds sampled by Creel et al., before (1962-1968) and after (2000-2006) wolf restoration using indices developed and calibrated for Rocky Mountain elk. Mean age-adjusted percentage body fat of female elk was similarly high in both periods (9.0% plus or minus 0.9% pre-wolf; 8.9% plus or minus 0.8% post-wolf). Estimated pregnancy rates (proportion of females that were pregnant) were 0.91 pre-wolf and 0.87 post-wolf for 4-9 year-old elk (95% CI on difference = -0.15 to 0.03, P = 0.46) and 0.64 pre-wolf and 0.78 post-wolf for elk >9 years old (95% CI on difference = -0.01 to 0.27, P = 0.06). Thus, there was little evidence in these data to support strong effects of wolf presence on elk pregnancy. We caution that multiple lines of evidence and/or strong validation should be brought to bear before relying on indirect measures of how predators affect pregnancy rates.

Equivalence tests and confidence interval estimates are based on a null hypothesis that a parameter estimate is either outside (inequivalence hypothesis) or inside (equivalence hypothesis) an equivalence region, depending on the question of interest and assignment of risk. The former approach, often referred to as bioequivalence testing, is often used in regulatory settings because it reverses the burden of proof compared to a standard test of significance, following a precautionary principle for environmental protection. Unfortunately, many applications of equivalence testing focus on establishing average equivalence by estimating differences in means of distributions that do not have homogeneous variances. I discuss how to compare equivalence across quantiles of distributions using confidence intervals on quantile regression estimates that detect differences in heterogeneous distributions missed by focusing on means. I used one-tailed confidence intervals based on inequivalence hypotheses in a two-group treatment-control design for estimating bioequivalence of arsenic concentrations in soils at an old ammunition testing site and bioequivalence of vegetation biomass at a reclaimed mining site. Two-tailed confidence intervals based both on inequivalence and equivalence hypotheses were used to examine quantile equivalence for negligible trends over time for a continuous exponential model of amphibian abundance.

Postspawn steelhead were captured at a weir in 2002-2005. Scale analysis indicated multiple migratory life histories and spawning behaviors. Acoustic tags were implanted in 99 kelts (2002-2003), and an array of acoustic receivers calculated the average speed of outmigration, timing of saltwater entry, and duration of residency in the vicinity of the river mouth. Ocean migration data were recovered from two archival tags implanted in kelts in 2004 (one male and one female). Archival tags documented seasonal differences in maximum depth and behavior with both fish spending 97% of time at sea <6 m depth (day and night). All study fish were double tagged with passive integrated transponder (PIT) tags implanted in the body cavity. Less than 4% of PIT tags were retained in postspawn steelhead. Molecular genetics demonstrated no significant differences in genetic population structure across years or among spawning life history types, suggesting a genetically panmictic population with highly diverse life history characteristics in the Ninilchik River.Original Abstract: Des etiquettes acoustiques et des etiquettes a archivage nous ont permis de suivre les migrations en eau douce et en mer de becards de la truite arc-en-ciel anadrome (Oncorhynchus mykiss) apres la fraie dans la riviere Ninilchik, Alaska, E.-U. Les truites arc-en-ciel apres la fraie ont ete capturees a un deversoir en 2002-2005. Une analyse hierarchique revele l'existence de multiples cycles biologiques migratoires et comportements reproducteurs. Nous avons muni 99 becards d'etiquettes acoustiques (2002-2003) et un reseau de recepteurs acoustiques a permis de calculer la vitesse de migration vers la mer, le calendrier de l'entree en eau salee et la duree de residence dans les environs de l'embouchure de la riviere. Les donnees de migration en mer ont ete obtenues de deux etiquettes a archivage fixees a des becards en 2004 (un male et une femelle). Les etiquettes a archivage ont releve des differences saisonnieres dans la profondeur maximale et le comportement; les deux poissons ont passe 97 % de leur temps en mer a une profondeur <6 m (jour et nuit). Tous les poissons utilises dans l'etude portaient aussi une etiquette PIT (transpondeur integre passif) implantee dans la cavite corporelle. Moins de 4 % des etiquette PIT ont ete retenues chez les becards apres la fraie. Une analyse genetique moleculaire ne montre aucune difference significative de structure genetique de la population, ni d'une annee a l'autre, ni en fonction des types de cycle biologique reproducteur, ce qui laisse croire a l'existence dans la Ninilchik d'une population genetiquement panmictique possedant des caracteristiques hautement diversifiees de cycle biologique.

To help improve age constraints, single grains of glauconitic minerals taken from sandstone and limestone in two Proterozoic sequences in the Pranhita-Godavari Valley and the Chattisgarh basin were analyzed by the super(40)Ar/ super(39)Ar incremental heating method. Analysis of the age spectra distinguishes between ages that are interpreted to reflect the time of glauconite formation, and anomalous ages that result from inherited argon or postcrystallization heating. The analyses indicate an age of 1686 plus or minus 6 Ma for the Pandikunta Limestone and 1566 plus or minus 6 Ma for the Ramgundam Sandstone, two units in the western belt of Proterozoic sequences in Pranhita-Godavari Valley. Glauconite from the Chanda Limestone, in the upper part of this sequence, contains inherited super(40)Ar but is interpreted to reflect an age of ca. 1200 Ma. Glauconite from the Somanpalli Group in the eastern belt of the Pranhita-Godavari Valley gives an age of 1620 plus or minus 6 Ma. In the Chattisgarh basin, glauconite from two units gives disturbed ages that suggest a period of regional heating in the Chattisgarh basin at ca. 960-1000 Ma. These new ages indicate that these sequences are 200-400 m.y. older than previously recognized, which has important implications for geochemical studies of Mesoproterozoic ocean redox conditions in addition to providing important constraints on regional tectonics and lithostratigraphy.

Rehabilitation of impaired reservoirs is hindered by the lack of a method suitable for scoring impairment status. To address this limitation, an index of reservoir habitat impairment (IRHI) was developed by merging 14 metrics descriptive of common impairment sources, with each metric scored from 0 (no impairment) to 5 (high impairment) by fisheries scientists with local knowledge. With a plausible range of 5 to 25, distribution of the IRHI scores ranged from 5 to 23 over 482 randomly selected reservoirs dispersed throughout the USA. The IRHI reflected five impairment factors including siltation, structural habitat, eutrophication, water regime, and aquatic plants. The factors were weakly related to key reservoir characteristics including reservoir area, depth, age, and usetype, suggesting that common reservoir descriptors are poor predictors of fish habitat impairment. The IRHI is rapid and inexpensive to calculate, provides an easily understood measure of the overall habitat impairment, allows comparison of reservoirs and therefore prioritization of restoration activities, and may be used to track restoration progress. The major limitation of the IRHI is its reliance on unstandardized professional judgment rather than standardized empirical measurements.

We examined how habitat suitability for delta smelt (Hypomesus transpacificus), a state and federally protected species, might be affected by changes in outflow in the San Francisco Estuary due to future development and climate change. Forty years of sampling data collected during fall from 1967 to 2008 were examined to define abiotic habitat suitability for delta smelt as a function of salinity and water transparency, and to describe long-term trends in habitat conditions. The annual habitat index we developed, which incorporated both quantity and quality of habitat, decreased by 78% over the study period. Future habitat index values under seven different development and climate change scenarios, representing a range of drier and wetter possibilities, were predicted using a model which related estuarine outflow to the habitat index. The results suggested that each of the scenarios would generally lead to further declines in delta smelt habitat across all water year types. Recovery targets for delta smelt will be difficult to attain if the modeled habitat conditions are realized.

We compared soil properties, vegetation, nekton communities, and delta super(13)C and delta super(15)N isotope values of blue crab muscle and hepatopancreas tissue and primary producers at created (5-24years old) and paired reference marshes in SW Louisiana. Paired contrasts indicated that created and reference marshes supported equivalent plant and nekton communities, but differed in soil characteristics. Stable isotope indicators examining blue crab food web support found that the older marshes (8years+) were characterized by comparable trophic diversity and breadth compared to their reference marshes. Interpretation of results for the youngest site was confounded by the fact that the paired reference, which represented the desired end goal of restoration, contained a greater diversity of basal resources. Stable isotope techniques may give coastal managers an additional tool to assess functional equivalency of created marshes, as measured by trophic support, but may be limited to comparisons of marshes with similar vegetative communities and basal resources, or require the development of robust standardization techniques.

Instead, hundreds of manatees aggregate at artificial canals, basins, and natural deep water sites that act as passive thermal refugia (PTR). Monitoring at two canal sites revealed temperature inverted haloclines, which provided warm salty bottom layers that generally remained above temperatures considered adverse for manatees. At the largest PTR, the warmer bottom layer disappeared unless significant salt stratification was maintained by upstream freshwater inflow over a persistent tidal wedge. A detailed three-dimensional hydrology model showed that salinity stratification inhibited vertical convection induced by atmospheric cooling. Management or creation of temperature inverted haloclines may be a feasible and desirable option for resource managers to provide passive thermal refugia for manatees and other temperature sensitive aquatic species.

The experiments were conducted at 330 and 350 degree C for 72 h to determine the effects of water during kerogen decomposition to polar-rich bitumen and subsequent bitumen decomposition to hydrocarbon-rich oil. The results showed that the role of water was more significant in bitumen decomposition to oil at 350 degree C than in kerogen decomposition to bitumen at 330 degree C. At 350 degree C, the hydrous experiment generated 29% more total hydrocarbon product and 33% more C sub(15+) hydrocarbons than the anhydrous experiment. This is attributed to water dissolved in the bitumen serving as a source of hydrogen to enhance thermal cracking and facilitate the expulsion of immiscible oil. In the absence of water, cross linking is enhanced in the confines of the rock, resulting in formation of pyrobitumen and molecular hydrogen. These differences are also reflected in the color and texture of the recovered rock. Despite confining liquid-water pressure being 7-9 times greater in the hydrous experiments than the confining vapor pressure in the anhydrous experiments, recovered rock from the former had a lighter color and expansion fractures parallel to the bedding fabric of the rock. The absence of these open tensile fractures in the recovered rock from the anhydrous experiments indicates that water promotes net-volume increase reactions like thermal cracking over net-volume decrease reactions like cross linking, which results in pyrobitumen. The results indicate the role of water in hydrocarbon and petroleum formation from Type-I kerogen is significant, as reported for Type-II kerogen.

Several source apportionment methods were utilized for RoMANS, including the Trajectory Mass Balance (TrMB) Model, a receptor-based method in which the hourly measured concentrations are the dependent variables and the residence times of back trajectories in several source regions are the independent variables. The regression coefficients are estimates of the mean emissions, dispersion, chemical transformation, and deposition between the source areas and the receptors. For RoMANS, a new ensemble technique was employed in which input parameters were varied to explore the range, variability, and model sensitivity of source attribution results and statistical measures of model fit over thousands of trials for each set of concentration measurements. Results showed that carefully chosen source regions dramatically improved the ability of TrMB to reproduce temporal patterns in the measured concentrations, and source attribution results were also very sensitive to source region choices. Conversely, attributions were relatively insensitive to trajectory start height, trajectory length, minimum endpoints per source area, and maximum endpoint height, as long as the trajectories were long enough to reach contributing source areas and were not overly restricted in height or horizontal location. Source attribution results estimated that more than half the ammonia and 30-45% of sulfur dioxide and other nitrogen-containing species at the RoMANS core site were from sources within the state of Colorado. Approximately a quarter to a third of the sulfate was from within Colorado.

Prior to the wide-scale deployment of wind turbines, fatal collisions of migratory bats with anthropogenic structures were rarely reported and likely occurred very infrequently. There are no other well-documented threats to populations of migratory tree bats that cause mortality of similar magnitude to that observed at wind turbines. Just three migratory species comprise the vast majority of bat kills at turbines in North America and there are indications that turbines may actually attract migrating individuals toward their blades. Although fatality of certain migratory species is consistent in occurrence across large geographic regions, fatality rates differ across sites for reasons mostly unknown. Cumulative fatality for turbines in North America might already range into the hundreds of thousands of bats per year. Research into the causes of bat fatalities at wind turbines can ascertain the scale of the problem and help identify solutions. None of the migratory bats known to be most affected by wind turbines are protected by conservation laws, nor is there a legal mandate driving research into the problem or implementation of potential solutions.

The presented research evaluates how the degree of cementation controls the evolution of steep sand slopes and shows that the detailed slope geometry is important in determining the characteristics of the failure mode, which in turn, guide the selection of an appropriate stability analysis method. Detailed slope-profile cross sections derived from terrestrial lidar surveying of otherwise inaccessible cemented sand cliffs are used to investigate failure modes in weakly cemented [unconfined compressive strength (UCS)<30 kPa] and moderately cemented (308 m) Detroit River using an anchor and buoy system.

However, ongoing conflicting human uses of these waters for activities such as waste disposal, water withdrawals, shoreline development, shipping, recreation, and fishing have altered many of the chemical, physical, and biological processes of the Detroit River. Of particular interest and concern to resource managers and stakeholders is the significant loss and impairment of fish spawning and nursery habitat that led to the decline in abundance of most fish species using this ecosystem. Lake sturgeon (Acipenser fulvescens) populations for example, were nearly extirpated by the middle of the 20th century, leaving only a small fraction of their former population. Fisheries managers recognized that the loss of suitable fish spawning habitat is a limiting factor in lake sturgeon population rehabilitation in the Detroit River. In efforts to remediate this beneficial water use impairment, a reef consisting of a mixture of natural rock and limestone was constructed at the upstream end of Fighting Island in 2008. This paper focuses on the response by lake sturgeon to the different replicates of suitable natural materials used to construct the fish spawning habitat at Fighting Island in the Detroit River. Pre-construction fisheries assessment during 2006-2008 showed that along with the presence of adult lake sturgeon, spawning conditions were favorable. However, no eggs were found in assessments conducted prior to reef construction.

Model organisms in laboratory settings form the basis for the assignment of gene function, and the ecological context of gene function is lacking. This work addresses this shortcoming by investigating expressed genes of sockeye salmon (Oncorhynchus nerka) muscle tissue. We compared morphology and gene expression in natural juvenile sockeye populations related to river and lake habitats. Based on previously documented divergent morphology, feeding strategy, and predation in association with these distinct environments, we expect that burst swimming is favored in riverine population and continuous swimming is favored in lake-type population. In turn we predict that morphology and expressed genes promote burst swimming in riverine sockeye and continuous swimming in lake-type sockeye. Results: We found the riverine sockeye population had deep, robust bodies and lake-type had shallow, streamlined bodies. Gene expression patterns were measured using a 16 k microarray, discovering 141 genes with significant differential expression. Overall, the identity and function of these genes was consistent with our hypothesis. In addition, Gene Ontology (GO) enrichment analyses with a larger set of differentially expressed genes found the "biosynthesis" category enriched for the riverine population and the "metabolism" category enriched for the lake-type population. Conclusions: This study provides a framework for understanding sockeye life history from a transcriptomic perspective and a starting point for more extensive, targeted studies determining the ecological context of genes.

Although there is general guidance on sampling techniques for population assessment of freshwater mussels, the actual performance of sampling designs can depend critically on the population density and spatial distribution at the project site. To evaluate various sampling designs, we simulated sampling of populations, which varied in density and degree of spatial clustering. Because of logistics and costs of large river sampling and spatial clustering of freshwater mussels, we focused on adaptive and non-adaptive versions of single and two-stage sampling. The candidate designs performed similarly in terms of precision (CV) and probability of species detection for fixed sample size. Both CV and species detection were determined largely by density, spatial distribution and sample size. However, designs did differ in the rate that occupied quadrats were encountered. Occupied units had a higher probability of selection using adaptive designs than conventional designs. We used two measures of cost: sample size (i.e. number of quadrats) and distance travelled between the quadrats. Adaptive and two-stage designs tended to reduce distance between sampling units, and thus performed better when distance travelled was considered. Based on the comparisons, we provide general recommendations on the sampling designs for the freshwater mussels in the UMR, and presumably other large rivers.

Its purpose is to provide an accurate and up-to-date temporal and geological framework for the marsh, of which most is new information (plus a compilation of historical and recent information), that is directly relevant to the restoration effort and also is relevant to short-term and long-term land management decisions regarding this natural resource. Analysis of field evidence, aerial photography, and published maps has revealed an accelerating rate of erosion and marsh loss at Dyke Marsh, which now appears to put at risk the short term survivability of this marsh. The destabilization of Dyke Marsh is outlined here, spanning an approximately 70-year time interval (1940-2010). This freshwater tidal marsh has shifted from a semi-stable net depositional environment (1864-1937) into a strongly erosional one, during a time when it currently is in early-phase planning for comprehensive restoration. The marsh has been deconstructed over the past 70 years by a combination of manmade and natural causes. The marsh initially experienced a strong destabilizing period between 1940 and 1972 by direct dredge mining of the marsh surface. By 1976 the marsh had entered a net destructive phase, where it remains at present. Photoanalysis of time-sequence aerial photographs of Dyke Marsh enabled us to calculate shoreline erosion estimates for this marsh over 19 years (1987-2006), as well as to quantify overall marsh acreage for 6 calendar years spanning an approximately 70 year interval (1937-2006). Photo overlay of a historic map enabled us to extend our whole-marsh acreage calculations back to 1883. Both sets of analyses were part of a geologic framework study in support of current efforts by the National Park Service (NPS) to restore this urban wetland. Two time intervals were selected for our shoreline erosion analyses, based on image quality and availability: 1987 to 2002, and 2002 to 2006. The more recent time interval shows a marked increase in erosion in the southern part of Dyke Marsh, following a wave-induced breach of a small peninsula that had protected its southern shoreline. Field observations and analyses of annual aerial imagery between 1987 and 2006 revealed a progressive increase in wave-induced erosion that presently is deconstructing Hog Island Gut, the last significant tidal creek network within the Dyke Marsh. These photo analyses documented an overall average westward shoreline loss of 6.0 to 7.8 linear feet per year along the Potomac River during this 19-year time interval. Additionally, photographic evidence documented that lateral erosion now is capturing existing higher order tributaries in the Hog Island Gut. Wave-driven stream piracy is fragmenting the remaining marsh habitat, and therefore its connectivity, relatively rapidly, causing the effective mouth of the Hog Island Gut tidal network to retreat headward visibly over the past several decades. Based on our estimates of total marsh area in the Dyke Marsh derived from 1987 aerial imagery, as much as 12 percent of the central part of the marsh has eroded in the 19 year period we studied (or approximately 7.5 percent of the original approximately 78.8 acres of 1987 marshland). Shoreline loss estimates for marsh parcels north and south of our study area have not yet been analyzed, although annual aerial photos from 1987 to 2002 confirm visible progressive shoreline loss in those areas over this same time interval.

The two-dimensional, laterally averaged model CE-QUAL-W2 was used to simulate water velocity, ice cover, water temperature, specific conductance, dissolved and suspended solids, dissolved oxygen, total nitrogen, ammonia, nitrate, total phosphorus, orthophosphate, dissolved and particulate organic matter, and three algal groups. The Link-Keno model successfully simulated the most important spatial and temporal patterns in the measured data for this 4-year time period. The model calibration process provided critical insights into water-quality processes and the nature of those inputs and processes that drive water quality in this reach. The model was used not only to reproduce and better understand water-quality conditions that occurred in 2006-09, but also to test several load-reduction scenarios that have implications for future water-resources management in the river basin.

Springs ranging in temperature from 3 degrees C to 90 degrees C in the Norris Geyser Basin area were sampled for stable isotopes of hydrogen and oxygen, major and minor element chemistry, dissolved chlorofluorocarbons, and tritium. Groundwater near Norris Geyser Basin is comprised of two distinct systems: a shallow, cool water system and a deep, high-temperature hydrothermal system. These two end-member systems mix to create springs with intermediate temperature and composition. Using multiple tracers from a large number of springs, it is possible constrain the distribution of possible flow paths and refine conceptual models of groundwater circulation in and around a large, complex hydrothermal system.

AN - 919632960; 2012-017045 AB - We use the stratigraphy of floodplains on Alaska's North Slope to describe how tundra watersheds responded to climate changes over the last 15,000 calibrated years BP (15 cal ka BP). Two episodes of extremely rapid floodplain alluviation occurred during the Pleistocene-Holocene transition, one between 14 and 12.8 cal ka BP and the other between 11.5 and 9.5 cal ka BP. These aggradation episodes coincided with periods of warming in summer when cottonwood (Populus balsamifera L.) expanded its range, peatlands became established, and widespread thermokarst occurred. The two aggradation episodes were separated by a period of floodplain incision during the Younger Dryas under cooler and possibly drier conditions. At times of increasing summer warmth, melting permafrost and enhanced precipitation probably triggered widespread mass wasting on hillslopes that overwhelmed the capacity of streams to transport sediment downstream, and rapid floodplain aggradation resulted. After peatlands became widespread in the early Holocene, rivers slowly incised their valley fills. Because major pulses of sediment input were limited to times of rapid thaw and increasing moisture, many floodplains on the North Slope have been effectively decoupled from upstream hillslopes for much of the past 15,000 years. Our findings: (a) confirm the sensitivity of arctic watersheds to rapid warming in summer, (b) emphasize the importance of hillslope mass wasting in landscape-scale responses to climate change, and (c) suggest that the presence of peatland on this arctic landscape today has raised its geomorphic response threshold to climate warming compared to what it was 14,000 years ago.

However, phylogenetic studies have shown limited sequence divergence within the genus and between Graptemys oculifera and Graptemys flavimaculata relative to most other members of the Emydidae. Graptemys oculifera of the Pearl River drainage and G. flavimaculata of the Pascagoula River drainage have been recognized as species since 1890 and 1954, respectively. However, the description of G. flavimaculata was based on a limited number of morphological characters. Several of these characters overlap between G. flavimaculata and G. oculifera, and no attempt was made to test for significant morphological differentiation. In this study, we reevaluated the morphological and genetic distinctiveness of G. flavimaculata and G. oculifera with (1) multivariate statistical analyses of 44 morphological characters and (2) 1,560bp of sequence data from two mitochondrial genes (control region and ND4). The morphological and molecular analyses produced incongruent results. The principal components analysis ordinations separated the two species along a pigmentation gradient with G. flavimaculata having more yellow pigmentation than G. oculifera. Likewise, clustering analyses separated the specimens into two distinct groups with little overlap between the species. Our mitochondrial data supported previous findings of limited genetic differentiation between the two species. However, the results of our morphological analyses, in conjunction with recently published nuclear gene sequence data, support the continued recognition of the two species.

We investigated flood and paleoflood hydrology at strategic sites to determine the frequency and geographic extent of extreme floods within the basin for a dam safety application. Streamgage, historical, and paleoflood data were utilized to develop frequency curves at sites near Salida, Cotopaxi, Parkdale, and Pueblo. Soil/stratigraphic descriptions, radiocarbon dating, and hydraulic modeling were used to estimate paleoflood nonexceedance bounds at the four sites, which ranged from 400 to 2200 YBP for late Holocene surfaces to late Pleistocene surfaces near Cotopaxi. Peak-flow data are from lower-magnitude snowmelt runoff in May and June in the upper basin and from high-magnitude rainfall runoff from June to August in the lower basin. Flood frequency curves reflect this transition near Parkdale from snowmelt to extreme rainfall-runoff. For similar return periods, paleoflood peak discharges increase from about 480 m (super 3) /s upstream at Loma Linda to about 4250 m (super 3) /s downstream near Pueblo. This increase is attributed to the larger rainfall component derived from lower elevations between Loma Linda and Pueblo. Return periods for design floods at Pueblo Dam exceeded 10,000 years based on paleoflood frequency curve extrapolations.

Samplers were deployed at two different yet proximal shoreline locations, White and Farley Canyons, before and after exposure of sediment to air and subsequent resubmersion, which resulted from fluctuations in the water level of the reservoir. Before exposure to air, an observed increase in dissolved Mn concentrations and, at Farley Canyon, an observed decrease in dissolved U concentrations across and immediately below the sediment-water interface indicated reducing conditions in the sub-surface. After exposure and resubmersion of the sediment, pore water profiles at each site differed distinctly from those observed before the fluctuation in water level. At White Canyon, an increase in U concentrations and a decrease in Mn concentrations in pore water after exposure and subsequent resubmersion are suggestive of oxidative processes occurring during the period of sediment exposure. Data from Farley Canyon suggest that the same processes may be occurring, but to a lesser extent. Depth profiles of As and Pb were also examined, but were relatively featureless compared to those of Mn and U. At both sites, sediment evaluated for pore water chemistry in the second sampling was only fully resubmerged for 2-5 days prior to the second sampling event, yet reducing conditions were clearly evident in the Mn pore water profiles. This suggests that the dynamics of the biogeochemical processes occurring in surface sediment at Lake Powell are responsive on the timescale defined by the fluctuating water levels in the reservoir.

From 2000 to 2004, four dam-style water diversions were replaced with a series of rock vortex weirs (RVWs). The weirs were designed to allow fish passage while maintaining the ability to divert water into irrigation canals. We observed the new appearance of three species (juvenile Chinook salmon Oncorhynchus tshawytscha, juvenile coho salmon O. kisutch, and mountain whitefish Prosopium williamsoni) upstream of the RVWs, indicating successful restoration of longitudinal connectivity. We used passive integrated transponder (PIT) tags and instream PIT tag interrogation systems during 2004-2007 to evaluate upstream passage of small salmonids (<240 mm fork length) through one series of RVWs. We documented 109 upstream passage events by small salmonids through the series of RVWs; most of the events (81%) involved passage of rainbow trout O. mykiss or juvenile steelhead (anadromous rainbow trout). Small rainbow trout or steelhead ranging from 86 to 238 mm (adjusted fork length) were able to pass upstream through the RVWs, although a delay in fish passage at discharges below 0.32 m super(3)/s was detected in comparison with nearby control sections.

In fisheries where the demand for surplus production is high, an extensive assessment program is needed to achieve the opposing objectives of allowing adequate escapement and fully exploiting the available surplus. Knowledge of abundance is a critical element of such assessment programs. Abundance estimation using mark-recapture experiments in combination with telemetry has become common in recent years, particularly within Alaskan river systems. Fish are typically captured and marked in the lower river while migrating in aggregations of individuals from multiple populations. Recapture data are obtained using telemetry receivers that are co-located with abundance assessment projects near spawning areas, which provide large sample sizes and information on population-specific mark rates. When recapture data are obtained from multiple populations, unequal mark rates may reflect a violation of the assumption of homogeneous capture probabilities. A common analytical strategy is to test the hypothesis that mark rates are homogeneous and combine all recapture data if the test is not significant. However, mark rates are often low, and a test of homogeneity may lack sufficient power to detect meaningful differences among populations. In addition, differences among mark rates may provide information that could be exploited during parameter estimation. We present a temporally stratified mark-recapture model that permits capture probabilities and migratory timing through the capture area to vary among strata. Abundance information obtained from a subset of populations after the populations have segregated for spawning is jointly modeled with telemetry distribution data by use of a likelihood function. Maximization of the likelihood produces estimates of the abundance and timing of individual populations migrating through the capture area, thus yielding substantially more information than the total abundance estimate provided by the conventional approach. The utility of the model is illustrated with data for coho salmon O. kisutch from the Kasilof River in south-central Alaska.

Because the total market value of this fishery has declined by an average of US$3.3 million per year since 1993, the commercial fishery has been challenged to maintain profitability. We developed a bioeconomic simulation model of the Chesapeake Bay blue crab fishery to aid managers in determining which regulations will maximize revenues while ensuring a sustainable harvest. We compared 15 different management scenarios, including those implemented by Maryland and Virginia between 2007 and 2009, that sought to reduce female crab harvest and nine others that used seasonal closures, different size regulations, or the elimination of fishing for specific market categories. Six scenarios produced the highest revenues: the 2008 and 2009 Maryland regulations, spring and fall closures for female blue crabs, and 152- and 165-mm maximum size limits for females. Our most important finding was that for each state the 2008 and 2009 scenarios that implemented early closures of the female crab fishery produced higher revenues than the 2007 scenario, in which no early female closures were implemented. We conclude that the use of maximum size limits for female crabs would not be feasible despite their potentially high revenue, given the likelihood that the soft-shell and peeler fisheries cannot be expanded beyond their current capacity and the potentially high mortality rate for culled individuals that are the incorrect size. Our model results support the current use of seasonal closures for females, which permit relatively high exploitation of males and soft-shell and peeler blue crabs (which have high prices) while keeping the female crab harvest sustainable. Further, our bioeconomic model allows for the inclusion of an economic viewpoint along with biological data when target reference points are set by managers.

Postrelease (hooking) mortality may significantly shift the age structure and size structure of populations. To assess the possible influence of catch-and-release fishing on brook trout population structure, we applied data from several sources to build a deterministic population model that included age-classes up to age 5. To assess the potential effect of fishing, we examined the changes in population density and age structure at varying levels of angler effort (0-400 angler-hours.ha super(-1).y ear super(-1)) and hooking mortality rates (0-14%). Assuming a low (5%) hooking mortality rate, trophy brook trout density (ages 4 and 5) decreased by 50% at an angling intensity of 160 angler-hours.ha super(-1).y ear super(-1). As angling effort increased, the proportion of older fish (ages 3-5) declined further. At very high levels of angling effort (>300 angler-hours.ha super(-1).y ear super(-1)), age-4 and age-5 fish were eliminated from the population. Increases in postrelease mortality rates resulted in similar declines for older age-classes. The results of this simulation indicate that hooking mortality rates as might be common in catch-and-release fisheries may significantly shift the age structure of a population, thus reducing trophy angling potential.

Major components of the system included a digital video recorder, multiple underwater cameras, and specially fabricated substrate stakes. The innovative design of the substrate stakes allowed us to effectively observe nesting redbreast sunfish Lepomis auritus in a highly regulated river. Substrate stakes, which were constructed for the specific substratum complex (i.e., sand, gravel, and cobble) identified at our study site, were able to withstand a discharge level of approximately 300 m super(3)/s and allowed us to simultaneously record 10 active nests before and during water releases from the dam. We believe our technique will be valuable for other researchers that work in regulated rivers to quantify behavior of aquatic fauna in response to a discharge disturbance.

The northern Teshekpuk Lake Special Area (N-TLSA), a coastal plain ecosystem along the Beaufort Sea in northern Alaska, provides habitat for migratory waterbirds, caribou, and potentially, denning polar bears. The 60-km coastline of N-TLSA is experiencing increasing rates of coastline erosion and storm surge flooding far inland resulting in lake drainage and conversion of freshwater lakes to estuaries. These physical mechanisms are affecting upland tundra as well. To better understand how these processes are affecting habitat, we analyzed long-term observational records coupled with recent short-term monitoring. Nearly the entire coastline has accelerating rates of erosion ranging from 6m/year from 1955 to 1979 and most recently peaking at 17m/year from 2007 to 2009, yet an intensive monitoring site along a higher bluff (3-6masl) suggested high interannual variability. The frequency and magnitude of storm events appears to be increasing along this coastline and these patterns correspond to a greater number of lake tapping and flooding events since 2000. For the entire N-TLSA, we estimate that 6% of the landscape consists of salt-burned tundra, while 41% is prone to storm surge flooding. This offset may indicate the relative frequency of low-magnitude flood events along the coastal fringe. Monitoring of coastline lakes confirms that moderate westerly storms create extensive flooding, while easterly storms have negligible effects on lakes and low-lying tundra. This study of two interacting physical mechanisms, coastal erosion and storm surge flooding, provides an important example of the complexities and data needs for predicting habitat change and biological responses along Arctic land-ocean interfaces.

Identifying relations between stream ecological condition and urban intensity indicators such as impervious surface provides important, but insufficient information to effectively address planning and management needs in such areas. In this study we investigate those specific landscape metrics which are functionally linked to indicators of stream ecological condition, and in particular, identify those characteristics that exacerbate or mitigate changes in ecological condition over and above impervious surface. The approach used addresses challenges associated with redundancy of landscape metrics, and links landscape pattern and composition to an indicator of stream ecological condition across a broad area of the eastern United States. Macroinvertebrate samples were collected during 2000-2001 from forty-two sites in the Delaware River Basin, and landscape data of high spatial and thematic resolution were obtained from photointerpretation of 1999 imagery. An ordination-derived 'biotic score' was positively correlated with assemblage tolerance, and with urban-related chemical characteristics such as chloride concentration and an index of potential pesticide toxicity. Impervious surface explained 56% of the variation in biotic score, but the variation explained increased to as high as 83% with the incorporation of a second land use, cover, or configuration metric at catchment or riparian scales. These include land use class-specific cover metrics such as percent of urban land with tree cover, forest fragmentation metrics such as aggregation index, riparian metrics such as percent tree cover, and metrics related to urban aggregation. Study results indicate that these metrics will be important to monitor in urbanizing areas in addition to impervious surface.

We modified the 23-m super(2) bottomless lift net developed for sampling nekton (fish and decapod crustaceans) on the surface of salt marshes for use in tidal mangrove forests with a woody (as opposed to herbaceous) underground root system. As originally designed (Rozas, Mar Ecol Prog Ser 89:287-292, 1992), the lift net was buried directly in the marsh substrate. The net was raised at slack high tide thereby encircling nekton within the enclosed area. A chain-line on the net bottom prevented escape under the net once deployed. However, when we used this same design in tidal mangrove forests, the extensive woody roots and occasional slumping sediments resulted in uneven trenches that could not be cleared effectively during sample recovery. We made 3 modifications to the original net design: (i) lined the peat trenches with aluminum channels of uniform width and depth; (ii) replaced the previous chain-line with Velcro closures that directly attached the net to the inner face of the outer wall of the aluminum channel; and (iii) removed the subtidal pan previously used for concentrating the enclosed nekton at low tide, and filled in those depressions with on-site peat. In the modified version, the aluminum trench became the only subtidal refuge available to nekton, and it was from here that we collected the sample after the forest drained. These modifications permitted high clearing efficiency (93-100%) of fin-clipped individuals of two common species of estuarine resident fishes, Kryptolebias marmoratus (mangrove rivulus) and Bathygobius soporator (frillfin goby). Additionally, the density estimates of grass shrimp (Palaemonetes spp.) increased 10-fold post-modification.

Wetlands located near marine environments are subject to alterations in water chemistry due to storm surge during hurricanes. The objective of our study was to evaluate the effect of storm surge overwash on wetland amphibian communities. Thirty-two wetlands in northwestern Florida were sampled over a 45-month period to assess amphibian species richness and water chemistry. During this study, seven wetlands were overwashed by storm surge from Hurricane Dennis which made landfall 10 July 2005 in the Florida panhandle. This event allowed us to evaluate the effect of storm surge overwash on water chemistry and amphibian communities of the wetlands. Specific conductance across all wetlands was low pre-storm (<100 mu S/cm), but increased post-storm at the overwashed wetlands ( Chi =7,613 mu S/cm). Increased specific conductance was strongly correlated with increases in chloride concentrations. Amphibian species richness showed no correlation with specific conductance. One month post-storm we observed slightly fewer species in overwashed compared with non-overwashed wetlands, but this trend did not continue in 2006. More species were detected across all wetlands pre-storm, but there was no difference between overwashed and non-overwashed wetlands when considering all amphibian species or adult anurans and larval anurans separately. Amphibian species richness did not appear to be correlated with pH or presence of fish although the amphibian community composition differed between wetlands with and without fish. Our results suggest that amphibian communities in wetlands in the southeastern United States adjacent to marine habitats are resistant to the effects of storm surge overwash.

Traditionally these have been very challenging to analyze because of the limitations of available statistical tools. This seems to be changing, and these are exciting times to be involved with ecological statistics, not just because of the neo-Bayesian revival but also because of the proliferation of computationally intensive methods in general. It is now possible to fit much richer models to observational data than in the relatively recent past, which in turn has stimulated much interest in how to evaluate and compare such models. In such an immature, vibrant, and rapidly growing field, not everyone is going to agree on the best way to do things. This is reflected in the contrast of opinions offered by the discussants. Each offers a thoughtful and thought-provoking critique of our work that reflects the current thinking in a non-negligible segment of the ecological data analysis community. We want to thank them for their insights. Some discussants expressed concerns that our models are big, complex, and adventurous. Before we address the individual discussants, we want to develop a little background context that will help us consider these points. From traditional perspectives, there might be the appearance that we are fitting big models with high-dimension parameter spaces. But simple parameter counting in models such as ours gives a substantially inflated measure of their true parameter complexity (model degrees of freedom). What distinguishes our models from classical maximum likelihood models is that they are not just performing parameter estimation, they are performing function estimation as well. This means that unlike classical models, the complexity (model df) of each of our individual models is not fixed beforehand. Multi-model inference is essentially a theory of function estimation, it is useful to draw some parallels between our approach and some ideas in Burnham and Anderson's (1998; BA) popular treatment of multi-model inference, although we do not advocate an information-theoretic approach.

Hydrologic responses to Pleistocene climate change within a deep vadose zone in the eastern Mojave Desert at Yucca Mountain, Nevada, were evaluated by uranium-series dating of finely layered hyalitic opal using secondary ion mass spectrometry. Opal is present within cm-thick secondary hydrogenic mineral crusts coating floors of lithophysal cavities in fractured volcanic rocks at depths of 200 to 300m below land surface. Uranium concentrations in opal fluctuate systematically between 5 and 550I14g/g. Age-calibrated profiles of uranium concentration correlate with regional climate records over the last 300,000years and produce time-series spectral peaks that have distinct periodicities of 100- and 41-ka, consistent with planetary orbital parameters. These results indicate that the chemical compositions of percolating solutions varied in response to near-surface, climate-driven processes. However, slow (micrometers per thousand years), relatively uniform growth rates of secondary opal and calcite deposition spanning several glacial-interglacial climate cycles imply that water fluxes in the deep vadose zone remained low and generally buffered from the large fluctuations in available surface moisture during different climates. False-color cathodoluminesence image of a calcite blade tip from the deep vadose zone at Yucca Mountain, NV, showing growth layering in opal (orange) and calcite (blue). Light bands in opal are enriched in U. Circles show locations of spots analyzed for U-series dating along with ages, in thousands of years (ka), representing deposition of U-rich layers during drier climate cycles. Black lines drawn along growth surfaces in calcite correlate opal layers with similar U concentrations and ages. Average mineral growth rates for the patch of opal in the upper central part of the image are ~1.54 km/ka and remained uniform over at least the last 300ka despite large fluctuations in effective surface moisture.

A non-radioactive thiaminase assay was described in 2007, but a direct comparison with the radioactive super(14)C-thiamine method which has been in use for more than 30 years has not been reported. The objective was to measure thiaminase activity in forage fish (alewife Alosa pseudoharengus, rainbow smelt Osmerus mordax, and slimy sculpin Cottus cognatus) consumed by predators that manifest thiamine deficiency using both methods. Modifications were made to the colorimetric assay to improve repeatability. Modification included a change in assay pH, enhanced sample clean-up, constant assay temperature (37 degree C), increase in the concentration of 4-nitrothiophenol (4NTP) and use of a spectrophotometer fitted with a 0.2 cm cell. A strong relationship between the two assays was found for 51 alewife (R super(2) = 0.85), 36 smelt (R super(2) = 0.87) and 20 sculpin (R super(2) = 0.82). Thiaminase activity in the colorimetric assay was about 1000 times higher than activity measured by the radioactive method. Application of the assay to fish species from which no thiaminase activity has previously been reported resulted in no 4NTP thiaminase activity being found in bloater Coregonus hoyi, lake trout Salvelinus namaycusch, steelhead trout Oncorhynchus mykiss or Chinook salmon Oncorhynchus tshawytscha. In species previously reported to contain thiaminase, 4NTP thiaminase activity was measured in bacteria Paenibacillus thiaminolyticus, gizzard shad Dorosoma cepedianum, bracken fern Pteridium aquilinum, quagga mussel Dreissena bugensis and zebra mussels D. polymorpha.

However, relatively little recent, broad-scale, or quantitative information exists on shorebird use of staging areas in this region. To locate possible shorebird concentration areas in the littoral zone of the ACP, we conducted aerial surveys from the southwest end of Kasegaluk Lagoon on the Chukchi Sea to Demarcation Point on the Beaufort Sea during the summers of 2005-07. These surveys identified persistent within- and between-year concentrations of staging shorebirds at Peard Bay, Point Barrow/Elson Lagoon, Cape Simpson, and Smith Bay to Cape Halkett. Among river deltas in the Beaufort Sea, the Sagavanirktok and Kongakut deltas had large concentrations of staging shorebirds. We also collected data on shorebird community characteristics, staging phenology, and habitat use in 2005 and 2006 by conducting land-based surveys at six camps: Kasegaluk Lagoon, Peard Bay, Point Barrow/Elson Lagoon, Colville Delta, Sagavanirktok Delta, and Okpilak Delta. The shorebird community was more even and diverse (evenness E and Shannon Weiner H') along the Beaufort Sea compared to the Chukchi Sea and in 2005 versus 2006. Staging phenology varied by species and location and differed for several species from that reported in previous studies. Our results suggest the existence of three foraging habitat guilds among the shorebird species observed in this study: gravel beach, mudflat, and salt marsh/pond edge. A comparison to data collected in the mid-1970s suggests that these foraging associations are conserved through time. Results from this research will be useful to land managers for monitoring the effects of changing environmental conditions and human activity on shorebirds and their habitats in Arctic Alaska.Original Abstract: Des etudes aviaires realisees dans les annees 1970 sur la plaine cotiere de l'Arctique en Alaska ont permis de constater que les habitats du littoral cotier revetent de l'importance pour les oiseaux de rivage nicheurs de l'Arctique en halte migratoire avant la migration d'automne. Cependant, relativement peu d'information recente, a grande echelle ou quantitative existe a propos de l'utilisation que font les oiseaux de rivage des haltes migratoires de cette region. Afin de localiser des zones de concentration possibles d'oiseaux de rivage dans la region littorale de la plaine cotiere de l'Arctique, nous avons effectue des leves aeriens du sud-ouest de la lagune Kasegaluk dans la mer des Tchouktches jusqu'a Demarcation Point dans la mer de Beaufort au cours des etes allant de 2005 a 2007. Ces leves ont permis de reperer des concentrations durables d'oiseaux de rivage en halte migratoire au cours d'une meme annee ainsi que d'une annee a l'autre a la baie Peard, a pointe Barrow et a la lagune Elson, au cap Simpson de meme que de la baie Smith jusqu'au cap Halkett. Parmi les deltas de rivieres de la mer de Beaufort, les deltas Sagavanirktok et Kongakut comptaient de fortes concentrations d'oiseaux de rivage en halte migratoire. Nous avons egalement recueilli des donnees sur les caracteristiques des populations d'oiseaux de rivage, sur la phenologie des haltes migratoires de meme que sur l'utilisation des habitats en 2005 et en 2006 au moyen de leves terrestres effectues a six camps, soit celui de la lagune Kasegaluk, de la baie Peard, de la pointe Barrow et de la lagune Elson, du delta Colville, du delta Sagavanirktok et du delta Okpilak. La population d'oiseaux de rivage etait plus homogene et diverse (homogeneite E et Shannon Weiner H') le long de la mer de Beaufort comparativement a la mer des Tchouktches, ainsi qu'en 2005 par rapport a 2006. La phenologie en halte migratoire variait selon les especes et les emplacements, et differait pour plusieurs especes de celles signalees dans le cadre d'etudes ulterieures. Nos resultats laissent croire a l'existence de trois guildes d'habitats de fourrage chez les especes d'oiseaux de rivage observees dans cette etude: plage de gravier, vasiere et marais salant ou bordure d'etang. La comparaison des donnees recueillies au milieu des annees 1970 laisse entendre que ces associations de fourrage se sont conservees au fil du temps. Les resultats decoulant de cette recherche seront utiles aux gestionnaires de terres dans le cadre de la surveillance des effets des conditions environnementales changeantes et de l'activite humaine sur les oiseaux de rivage et leurs habitats de l'Arctique alaskien.

In previous interpretations of these analyses, data were expressed in weight percent and parts per million, and thus were subject to the effect of the constant-sum phenomenon. In a new approach to the data, this effect was removed by using centered log-ratio transformations to 'open' the mineralogical and geochemical arrays. Multivariate analyses, including principal component and linear discriminant analyses, of the centered log-ratio data reveal the effects of soil-forming processes, including soil parent material, weathering, and soil age, at the continental-scale of the data arrays that were not readily apparent in the more conventionally presented data. Linear discriminant analysis of the data arrays indicates that the majority of the soil samples collected along the transects can be more successfully classified with Level 1 ecological regional-scale classification by the soil geochemistry than soil mineralogy. A primary objective of this study is to discover and describe, in a parsimonious way, geochemical processes that are both independent and inter-dependent and manifested through compositional data including estimates of the elements and corresponding mineralogy.

This is a wintering area on the southern coast of California. We obtained locations from five adult males and three adult females every 3rd day through August. Average date of departure from the wintering area was 15 March (SE = 3days). We documented extended stopovers of greater than or equal to 30days for several northern pintails that could have accommodated nesting attempts (San Joaquin Valley, southwestern Montana, southern Alberta, north-central Nevada) or post-nesting molt (eastern Oregon, south-central Saskatchewan, northern Alaska, central Alberta). Wintering northern pintails from the southern coast of California used a wide range of routes, nesting areas, and schedules during migration in spring, which was consistent with the larger, wintering population in the Central Valley of California. Therefore, conservation of habitat that is targeted at stopover, nesting, and molting areas will benefit survival and management of both wintering populations.

UV can be hazardous to some amphibians, but the resultant effects depend on a variety of environmental and behavioral factors. In this study, the potential effects of UV on the Northwestern Salamander, Ambystoma gracile, from three lakes were assessed in the laboratory using a solar simulator. We measured the survival of embryos and the survival and growth of larvae exposed to four UV treatments in controlled laboratory studies, the UV absorbance of egg jelly, oviposition depths in the lakes, and UV absorbance in water samples from the three lakes. Hatching success of embryos decreased in the higher UV treatments as compared to the control treatments, and growth of surviving larvae was significantly reduced in the higher UVB irradiance treatments. The egg jelly exhibited a small peak of absorbance within the UVB range (290-320nm). The magnitude of UV absorbance differed among egg jellies from the three lakes. Oviposition depths at the three sites averaged 1.10m below the water surface. Approximately 66% of surface UVB radiation was attenuated at 10-cm depth in all three lakes. Results of this study indicate that larvae may be sensitive to UVB exposure under laboratory conditions; however, in field conditions the depths of egg deposition in the lakes, absorbance of UV radiation by the water column, and the potential for behavioral adjustments may mitigate severe effects of UV radiation.

Since completion of Libby Dam upstream from the spawning reach in 1972, 1974 is the only year with documented significant recruitment of juvenile fish. Where successful in other rivers, white sturgeon spawn over clean coarse material of gravel size or larger. The channel substrate in the current (2008) 18-km spawning reach is composed primarily of sand and some buried gravel; within a few kilometers upstream there is an extended reach of clean gravel, cobble, and bedrock. We used a quasi-three-dimensional flow and sediment-transport model along with the locations of collected sturgeon eggs as a proxy for spawning location from 1994 to 2002 to gain insight into spawning-habitat selection in a reach which is currently unsuitable due to the lack of coarse substrate. Spatial correlations between spawning locations and simulated velocity and depth indicate fish select regions of higher velocity and greater depth within any river cross section to spawn. These regions of high velocity and depth occur in the same locations regardless of the discharge magnitude as modeled over a range of pre- and postdam flow conditions. A flow and sediment-transport simulation shows high discharge, and relatively long-duration flow associated with predam flow events is sufficient to scour the fine sediment overburden, periodically exposing existing lenses of gravel and cobble as lag deposits in the current spawning reach. This is corroborated by video observations of bed surface material following a significant flood event in 2006, which show gravel and cobble present in many locations in the current spawning reach. Thus, both modeling and observations suggest that the relative rarity of extremely high flows in the current regulated flow regime is at least partly responsible for the lack of successful spawning; in the predam flow regime, frequent high flows removed the fine sediment overburden, unveiling coarse material and providing suitable substrate in the current spawning reach.

The goal of this paper was to develop a simple method for predicting baseflow buffering chemistry based on the hydrogeomorphic properties of ten nested watersheds in the Neversink River basin (2.0-176.0 km (super 2) ), an acid-sensitive basin in the Catskill Mountains, New York State. The tributaries and main reach watersheds have strongly contrasting mean baseflow ANC values and Ca (super 2+) concentrations, despite rather homogeneous vegetation, bedrock geology, and soils. A stepwise regression was applied to relate 13 hydrogeomorphic properties to the mean baseflow ANC values and Ca (super 2+) concentrations. The regression analysis showed that watersheds with lower ANC values had a higher mean ratio of 'quickflow' runoff to precipitation during 20 non-snowmelt runoff events (referred to as mean runoff ratio). The mean runoff ratio could explain at least 80% of the variability in mean baseflow ANC values and Ca (super 2+) concentrations among the ten watersheds. Greater mean runoff ratios also correlated with steeper slopes and greater drainage densities, thus allowing the prediction of baseflow ANC values (r (super 2) =0.75) and Ca (super 2+) concentrations (r (super 2) =0.77) with widely available spatial data alone. These results indicate that hydrogeomorphic properties can predict a watershed's sensitivity to acid deposition in regions where the spatial sources of stream buffering chemistry from the bedrock mineralogy and soils are fairly uniform.

We introduce a quantitative definition of pockmark morphology and, based on this definition, propose a three-step geomorphometric method to identify and extract pockmarks from high-resolution swath bathymetry. We apply this GIS-implemented approach to 25km2 of bathymetry collected in the Belfast Bay, Maine USA pockmark field. Our model extracted 1767 pockmarks and found a linear pockmark depth-to-diameter ratio for pockmarks field-wide. Mean pockmark depth is 7.6m and mean diameter is 84.8m. Pockmark distribution is non-random, and nearly half of the field's pockmarks occur in chains. The most prominent chains are oriented semi-normal to the steepest gradient in Holocene sediment thickness. A descriptive model yields field-wide spatial statistics indicating that pockmarks are distributed in non-random clusters. Results enable quantitative comparison of pockmarks in fields worldwide as well as similar concave features, such as impact craters, dolines, or salt pools.

This study was conducted to describe population dynamics of sand shiners including age structure, growth, mortality, and recruitment variability in 15 non-wadeable rivers in Iowa. Fish were collected during June-August (2007-2008) using a modified Missouri trawl, a seine, and boat-mounted electrofishing. Scales were removed for age and growth analysis. A total of 3,443 fish was sampled from 15 populations across Iowa, of which 676 were aged. Iowa's sand shiner populations consisted primarily of age-1 fish (53% of all fish sampled), followed by age-2 fish (30%), age-0 fish (15%), and age-3 fish (2%). Sand shiners grew an average of 38.5 mm (SE = 5.7) during their first year, 13.8 mm (4.5) during their second year, and 9.0 mm (6.9) during their third year. Total annual mortality varied from 35.0% to 92.3% among populations with a mean of 77.9% (0.2). Incremental mortality rates were 84.5% (0.2) between age 1 and age 2, and 92.0% (0.1) between age 2 and age 3. Recruitment was highly variable, as indicated by a mean recruitment variation index of -0.12 (0.54). Overall, the sand shiner was characterized by relatively low mean age, fast growth, high mortality, and high recruitment variability. Indices of sand shiner population dynamics were poorly correlated with habitat characteristics.

Water, sediment, and passive polar organic integrative samplers (POCIS) were analyzed for steroidal hormones, alkylphenols, bisphenol A, and other organic and inorganic molecular tracers to evaluate potential non-point source inputs into the lakes. Resident fish from the lakes were collected, and caged male fathead minnows were deployed to evaluate endocrine disruption, as indicated by the biological endpoints of plasma vitellogenin and gonadal histology. Endocrine disrupting chemicals, including bisphenol A, 17 beta -estradiol, estrone, and 4-nonylphenol were detected in 90% of the lakes at part per trillion concentrations. Endocrine disruption was observed in caged fathead minnows and resident fish in 90% of the lakes. The widespread but variable occurrence of anthropogenic chemicals in the lakes and endocrine disruption in fish indicates that potential sources are diverse, not limited to wastewater treatment plant discharges, and not entirely predictable based on trophic status and land use.

The total current heat flow from the caldera floor is estimated to be ~ 290 MW, and a geothermal power plant in Casa Diablo on the flanks of the resurgent dome (RD) generates ~40 MWe. The RD in the center of the caldera was uplifted by ~ 80 cm between 1980 and 1999 and was explained by most models as a response to magma intrusion into the shallow crust. This unrest has led to extensive research on geothermal resources and volcanic hazards in the caldera. Here we present results from precise, high-resolution, temperature-depth profiles in five deep boreholes (327-1,158 m) on the RD to assess its thermal state, and more specifically 1) to provide bounds on the advective heat transport as a guide for future geothermal exploration, 2) to provide constraints on the occurrence of magma at shallow crustal depths, and 3) to provide a baseline for future transient thermal phenomena in response to large earthquakes, volcanic activity, or geothermal production. The temperature profiles display substantial non-linearity within each profile and variability between the different profiles. All profiles display significant temperature reversals with depth and temperature gradients <50 C/km at their bottom. The maximum temperature in the individual boreholes ranges between 124.7 C and 129.5 C and bottom hole temperatures range between 99.4 C and 129.5 C. The high-temperature units in the three Fumarole Valley boreholes are at the approximate same elevation as the high-temperature unit in borehole M-1 in Casa Diablo indicating lateral or sub-lateral hydrothermal flow through the resurgent dome. Small differences in temperature between measurements in consecutive years in three of the wells suggest slow cooling of the shallow hydrothermal flow system. By matching theoretical curves to segments of the measured temperature profiles, we calculate horizontal groundwater velocities in the hydrothermal flow unit under the RD that range from 1.9 to 2.8 m/yr, which corresponds to a maximum power flowing through the RD of 3-4 MW. The relatively low temperatures and large isothermal segments at the bottom of the temperature profiles are inconsistent with the presence of magma at shallow crustal levels.

During an ongoing geoarchaeological survey of Portuguese Estremadura we identified uplifted Pleistocene sediments that record coastal features including raised beaches, tidal channels, muds, peat, and coastal dunes. Stratified concentrations of Middle Paleolithic artifacts were found at Mira Nascente and Praia Rei Cortico, two new sites in coastal wetland settings. The Mira Nascente locality yielded a chert-dominated lithic assemblage in a tidal flat setting dated to MIS 3. The raw material economy differs markedly from sites found in other landscape settings. Praia Rei Cortico is located near a thick peat deposit that formed in a freshwater coastal swamp and marsh likely dated to the Last Interglacial.

Using Mg/Ca ratios from ostracodes and oxygen isotopes from benthic foraminifera as proxies for temperature and precipitation-driven estuarine hydrography, results show that warmest temperatures in CB reached 16-17 degree C between 600 and 950CE (Common Era), centuries before the classic European Medieval Warm Period (950-1100CE) and peak warming in the Nordic Seas (1000-1400CE). A series of centennial warm/cool cycles began about 1000CE with temperature minima of similar to 8 to 9 degree C about 1150, 1350, and 1650-1800CE, and intervening warm periods (14-15 degree C) centered at 1200, 1400, 1500 and 1600CE. Precipitation variability in the eastern US included multiple dry intervals from 600 to 1200CE, which contrasts with wet medieval conditions in the Caribbean. The eastern US experienced a wet LIA between 1650 and 1800CE when the Caribbean was relatively dry. Comparison of the CB record with other records shows that the MCA and LIA were characterized by regionally asynchronous warming and complex spatial patterns of precipitation, possibly related to ocean-atmosphere processes.

The goal of some coal bed producers is to extend coal bed methane productivity and to utilize hydrocarbon wastes such as coal slurry to generate new methane. However, the process and factors controlling the process, and thus ways to stimulate it, are poorly understood. Subbituminous coal from a nonproductive well in south Texas was stimulated to produce methane in microcosms when the native population was supplemented with nutrients (biostimulation) or when nutrients and a consortium of bacteria and methanogens enriched from wetland sediment were added (bioaugmentation). The native population enriched by nutrient addition included Pseudomonas spp., Veillonellaceae, and Methanosarcina barkeri. The bioaugmented microcosm generated methane more rapidly and to a higher concentration than the biostimulated microcosm. Dissolved organics, including long-chain fatty acids, single-ring aromatics, and long-chain alkanes accumulated in the first 39 days of the bioaugmented microcosm and were then degraded, accompanied by generation of methane. The bioaugmented microcosm was dominated by Geobacter sp., and most of the methane generation was associated with growth of Methanosaeta concilii. The ability of the bioaugmentation culture to produce methane from coal intermediates was confirmed in incubations of culture with representative organic compounds. This study indicates that methane production could be stimulated at the nonproductive field site and that low microbial biomass may be limiting in situ methane generation. In addition, the microcosm study suggests that the pathway for generating methane from coal involves complex microbial partnerships.

For example, predictive models are increasingly being developed that use measures of watershed disturbance, including urban and agricultural land-use, as explanatory variables to predict various metrics of biological condition such as richness, tolerance, percent predators, index of biotic integrity, functional species traits, or even ordination axes scores. Our primary intent was to determine if effective models could be developed using watershed characteristics of disturbance to predict macroinvertebrate metrics among disparate and widely separated ecoregions. We aggregated macroinvertebrate data from universities and state and federal agencies in order to assemble stream data sets of high enough density appropriate for modeling in three distinct ecoregions in Oregon and California. Extensive review and quality assurance of macroinvertebrate sampling protocols, laboratory subsample counts and taxonomic resolution was completed to assure data comparability. We used widely available digital coverages of land-use and land-cover data summarized at the watershed and riparian scale as explanatory variables to predict macroinvertebrate metrics commonly used by state resource managers to assess stream condition. The "best" multiple linear regression models from each region required only two or three explanatory variables to model macroinvertebrate metrics and explained 41-74% of the variation. In each region the best model contained some measure of urban and/or agricultural land-use, yet often the model was improved by including a natural explanatory variable such as mean annual precipitation or mean watershed slope. Two macroinvertebrate metrics were common among all three regions, the metric that summarizes the richness of tolerant macroinvertebrates (RICHTOL) and some form of EPT (Ephemeroptera, Plecoptera, and Trichoptera) richness. Best models were developed for the same two invertebrate metrics even though the geographic regions reflect distinct differences in precipitation, geology, elevation, slope, population density, and land-use. With further development, models like these can be used to elicit better causal linkages to stream biological attributes or condition and can be used by researchers or managers to predict biological indicators of stream condition at unsampled sites.

Body fossils are extremely rare, and much of what is known about animals inhabiting this harsh ecosystem is based on trace fossils. Dinosaur footprints, which dominate the ichnofauna, are known primarily from interdunal deposits. A site within Dinosaur National Monument (DNM), UT, provides insight into the rare components of the fauna. Brasilichnium tracks occur on five different bedding plane surfaces within a crossbed set of dune sands. At the largest exposed surface (measuring 4m X 10m) over 300 Brasilichnium tracks are preserved. Average track width is 10mm. Tracks show push up rims along the heel impression and, rarely, show 4 toe impressions. The trackway of a large, unidentified vertebrate traverses the dune slope and cuts across the Brasilichnium trackways. At another horizon, the Brasilichnium tracks occur in association with two large scorpion trackways that indicate a leg spread of 10 cm. At all horizons, most tracks, both vertebrate and invertebrate, indicate the track makers were traveling up dune lee faces. The eolian cross bed laminae that bear the tracks can be traced downslope into horizontally laminated sand of the lowest 2m of that set of cross beds. This interval rests directly upon and truncates the large eolian cross beds of the set below. It consists of thin alternating red and yellow laminae, and contains several, large invertebrate traces, each consisting of a system of closely-spaced vertical and horizontal burrows extending through 30cm of section. We attribute these features to colonial arthropods. The DNM site is unusual and significant in two ways. First is the great abundance of Brasilichnium tracks on a single surface. Tracks on slip face deposits are generally considered to have been formed over a very short period of time, possibly during a single night. This suggests high population numbers for the trackmakers, probably synapsids, a group very poorly represented by body fossils in this Early Jurassic desert. Secondly, track surfaces can be traced to contemporaneous deposits at the base of the dune with evidence of invertebrate activity.

The fossil beds also preserve a fossil record in the overlying Quaternary sediments that aids in assessing the local terrestrial paleoecology prior to the last glacial maximum. Fragmentary material, associated with a mandible and molar tooth of a Mammuthus columbi, has been recovered near the Visitor Center in Pleistocene gravels. The tooth has been radiocarbon dated on purified collagen at 49,830 + or - 3290 (CAMS-22182), a date that exceeds the reliable range for radiocarbon dating. Buried with the mammoth fossils were pollen and spores from nearby plant communities that had accumulated in a terrestrial environment. Carbonate rock samples, associated with the mammoth, were prepared by having all external surfaces of the freshly exposed rock cleaned to eliminate contamination in microfractures or other flaws. Processing of the sample followed standard palynological techniques. The sample contained indigenous and reworked palynomorphs. The Pleistocene palynomorphs recovered were identified and included Pinus, Selaginella, Asteraceae, Juniperus, Abies, and fern spores. Soil fungi (Glomus-type) were prominent. The pollen flora suggests a dry climate. At least the 4-pored (exotic) Ulmoideae pollen type recovered closely resembles a Florissant type and may in fact be reworked from Eocene sediments of the Florissant Formation. Hence, this form may not reflect the environmental conditions at the time of the burial of the mammoth. This sample includes other potentially re-deposited palynomorphs from the Eocene Florissant Formation, including Carya, Ulmus, and Hystrix.

That publication heralded a new era for the systematic documentation of fossils throughout the National Park Service. This effort gathered data from published and unpublished sources about paleontological resources in the NPS, uncovered numerous "one-of-a-kind" paleontology stories from throughout the NPS, and added more than 75 parks to the list of NPS units with fossils. A written summary for each network park was produced, including an introduction, geologic background, and a summary of known and/or potential paleontological resources in the park. Museum collections and fossils found in cultural resource contexts were also assessed. The summaries included a list of preliminary resource management recommendations, a bibliography, and list of data sets. Although field work was not a part of the documentation process, report authors made recommendations for future field work where appropriate. The reports were reviewed by park staff and also underwent peer review. Between 2002 and 2006, 13 network reports were completed utilizing discretionary funds from individual networks. In 2006, the National Park Service Inventory and Monitoring (I&M) Program provided funding to systematically evaluate the remaining 19 networks. The final five networks were completed in 2010, marking the end of this effort. Throughout the process, the reports have evolved to include new levels comprehensiveness and are now cataloged in the NPS Natural Resource Technical Report Series. The National Park Service's comprehensive paleontological resource inventory supports paleontological resource stewardship, education and outreach efforts including field-based inventories, thematic inventories, National Fossil Day, and the Junior Paleontologist program. With these reports, the inventories form a foundation for future paleontological resource monitoring. Many thanks to the dozens of interns, contractors, geologists, paleontologists, NPS staff, I&M networks, and the national I&M Program that contributed to this unprecedented effort.

National Fossil Day is a celebration organized by the National Park Service partnering with the American Geological Institute to promote public awareness and stewardship of fossils, as well as to foster a greater appreciation of their scientific and educational value. Fossils are clues for understanding the history of life, past climates, and ancient landscapes. National Fossil Day was inspired by a mandate of the Paleontological Resources Preservation Act (PRPA), signed into law in March 2009. In addition to managing paleontological resources on federal lands using scientific principles, PRPA mandates establishing a program to increase public awareness about the significance of fossils. Fossils are non-renewable resources, requiring appropriate stewardship. As part of Earth Science Week, National Fossil Day aims to build on a program that reaches 40 million people a year. This year's Earth Science Week toolkit includes a "Fossils of the National Parks" poster, featuring a map showing more than 228 parks managed by the National Park Service that contain fossils. Fossils discovered on the nation's public lands preserve ancient life from all major eras of Earth's history, and from every major group of animal or plant. In the national parks, for example, fossils range from stromatolites in Glacier National Park to the remains of ice-age animals found in caves at Grand Canyon National Park. National Fossil Day is supported by partnerships with state and federal agencies, avocational groups, fossil sites, museums and professional organizations. Representatives from the National Earth Science Teachers Association, Paleontological Research Institution, and University of California Museum of Paleontology were integral in planning. Special events were held nationwide throughout the month of October at national, state and local parks, museums, schools, and other venues. On October 13, premiere events were held on the National Mall in Washington DC and at Grand Canyon National Park. The National Fossil Day concept was very well-received by the paleontology community and efforts are underway to expand National Fossil Day worldwide next year.

S. National Park Service ER - TY - JOUR T1 - Last interglacial sea-level history on Santa Barbara and Anacapa Islands, Channel Islands National Park, California AN - 913702785; 2012-010850 AB - The two smallest (each approximately 2.6 km sq.) islands in Channel Islands National Park, California are Anacapa Island (AI) and Santa Barbara Island (SBI). Both have a rich history of Quaternary interglacial periods and tectonics as marine terraces that dominate the insular landscapes. SBI has at least four terraces ( approximately 7.5 m, approximately 23 m, approximately 50 m and approximately 80 m) and AI has at least two ( approximately 11 m and approximately 83 m). Fossils are abundant in some of these terraces. Amino acid ratios in fossil mollusks (primarily Tegula) can be used to correlate the terraces with U-series-dated terraces elsewhere in the Channel Islands and mainland California. Both the approximately 11 m terrace on AI and the approximately 7.5 m terrace on SBI likely date to the last interglacial complex (marine isotope stage 5, or MIS 5). However, both may contain fossils from two high-sea stands of this complex, one at approximately 120 ka (MIS 5.5) and the other at approximately 100 ka (MIS 5.3). Evidence of similar reoccupation of 120 ka marine terraces by the 100 ka high stand is also found on San Nicolas Island, Point Loma, and Cayucos, California. These three localities and the approximately 7.5 m terrace on SBI contain mixtures of both extralimital southern (warm water) and extralimital northern (cool water) mollusks. We hypothesize that the warm-water forms date from the approximately 120 ka high sea stand and the cool-water forms date from the approximately 100 ka high sea stand. Correlation of the approximately 11 m terrace on AI and the approximately 7.5 m terrace on SBI with the approximately 120 ka high-sea stand allows calculation of average late Quaternary uplift rates. If we assume a +6 m sea level at approximately 120 ka (a commonly accepted value), then AI has been uplifted only approximately 5 m (average rate of 0.042 m/ka) and SBI has been uplifted only approximately 1.5 m (average rate of 0.012 m/ka) in the late Quaternary. These low uplift rates, if correct, explain why the approximately 120 ka terrace was reoccupied by the approximately 100 ka high-sea stand. The very low uplift rate for AI is consistent with little or no uplift in the late Quaternary documented for nearby Santa Cruz Island (SCI) reported by Pinter et al. (1998, GSA Bull. 110: 711-722). Low uplift rates for both SCI and AI are not consistent, however, with very high uplift rates ( approximately 1.5 m/ka) reported for the northern Channel Islands crustal block (including SCI and AI) by Chaytor et al. (2008; GSA Bull. 120: 1053-1071). The reason for these vastly different estimates of late Quaternary uplift rate is not understood and requires further study.

The National Environmental Policy Act (NEPA) is an altruistic law with well intentioned objectives but meeting the requirement of the "hard look" of this process oriented law presents problems to both the agencies and the proponent. Assuring this "hard look" includes a multi-disciplinary approach results in multiple agencies and multiple disciplines within each agency, which is further complicated with conflicting charters of the individual agencies. Anticipate a few state vs. federal primacy issues and the plot thickens even more. Analyzing the technical aspects while managing the inevitable political issues and public involvement of the proposed project results in a juggling act of Ringling Brothers proportions. An industry perspective will be provided about how this juggling act was managed at Smoky Canyon Mine as a 2003 proposed expansion was analyzed under NEPA and subsequently approved in 2008 Records of Decision from the Bureau of Land Management and United States Forest Service.

BLM's regulatory mine & reclamation plan (MRP) review process utilizes the National Environmental Policy Act (NEPA) as the vehicle for federal decision making related to MRP activities proposed to occur on and adjacent to federal leases. Open pit mining of Permean age phosphatic shale in Idaho poses a potential for and has caused releases of contaminants such as selenium from waste rock and overburden into land, vegetation, and water in and around the mining sites. Over the past decade, these releases have resulted in portions of some watersheds being listed as "impaired" under section 303(d) of the Clean Water Act. Over fifteen historic and active mining sites are now undergoing or have been identified for investigation and remediation of selenium and other contamination under the Comprehensive Environmental Response, Compensation & Liability Act (CERCLA). The contamination problem has been well documented since it was discovered in the late 1990's. Since that time, in order to prevent additional impacts, BLM's review of new phosphate MRP applications has incorporated state-of-the-art geochemical tests of waste rock. Hydrogeologic modeling, including infiltration, fate & transport, and steady-state analysis are then used to predict the nature and extent of possible impacts to water quality. Before a MRP can be approved, applicants are required to incorporate measures into the MRP to reduce or otherwise mitigate predicted impacts to within acceptable limits imposed by clean water statutes. State and federal agencies charged with overseeing those acts participate in BLM's NEPA process to provide direction on the nature and extent of predicted impacts that may be acceptable and the amount of any impact reduction that may be necessary for project approval. After BLM's approval of an MRP, additional modeling, changes to mining practices, and implementation of other measures may be necessary to address issues identified by environmental monitoring.

The Western Governors Association (WGA) collaborated with numerous stakeholders to develop the Western Renewable Energy Zones, identifying areas in 11 western states with vast renewable energy resources. The next steps support commercial transmission projects and their markets along with building interstate cooperation for transmission approvals, cost recoveries, and the evaluation of transmission strategies. A goal will be to facilitate the development of high voltage transmission to areas with high renewable energy and low or easily mitigated environmental impacts. The processing of renewable energy applications (existing and potential) for solar and wind applications and transmission lines were improved by providing complete, accurate, and easily accessible source documents, records, digital data and map products. Environmental analysis included balancing the benefits of renewable energy with the needs to protect other resources such as crucial wildlife habitat. Census records, cities, roads, and wildfire urban interface areas data show areas of increased community growth. The potential energy records are derived from the National Renewable Energy Laboratory models provided by the WGA. The probability classification system relates to electricity that could be produced (1500 MW of solar or wind and 500 MW of geothermal generating capacity), which is needed to support the delivery of energy to major centers. The United States Geological Survey provided estimates for the geothermal energy sites. The Western Interconnection is the electricity grid that includes the western states and is overseen by the Western Electricity Coordinating Council.

Non-invasive geophysical methods provide efficient alternatives to costly and invasive excavations, allowing archaeologists to analyze sites beforehand and to identify areas of interest. Most importantly, geophysical surveying has proven to be very effective in locating prehistoric and historic features. Less attention has been paid to the ability of geophysics to help archaeologists examine the stratigraphy of prehistoric earthworks. This expansion of archaeo-geophysics would help answer questions such as earthwork construction techniques and the geomorphology of sites, further reducing the need for invasive digging. For this research, we are analyzing two borrow pits located at the Mound City Group in Ross County, Ohio using five different geophysical methods. These methods include ground-penetrating radar, electrical resistance and conductivity, magnetic susceptibility, and magnetometry. These data will be ground-truthed using soil coring and trenches to identify the geophysical anomalies, providing us with a method of interpreting stratigraphy through geophysical data analysis.

Fatalities resulted from rock falls above Happy Isles (July 10, 1996) and Curry Village (June 13, 1999). A lawsuit, dismissed in 2010, claimed that septic leachate and water-tank overflows increased hydraulic pressures above stability thresholds in key fractures. Although evidence shows that the rock falls were not triggered hydrologically, in order to address lawsuit claims, we present hydrologic data showing that the water systems are unlikely triggers for rock falls from Glacier Point. During 1996, precipitation, which, as usual, was mostly snow, provided 30 million gallons of water upslope from the Happy Isles rock-fall source area; septic leachate provided 30 times less water (0.9 million gallons). It is unlikely that small amounts of leachate raised hydraulic pressures above those that occurred during infiltration of spring snowmelt. The variability of annual precipitation in the watershed during 1988-1997 is 10 times greater than the average annual volume of leachate from the septic system. Groundwater-levels measured in shallow monitoring wells at Glacier Point are highest during peak snow melt; it is likely that hydraulic pressures in cliff fractures also are highest then. Leachate is disposed only during the dry season when evapotranspiration rates are high and groundwater levels naturally decline--precluding elevated hydraulic pressures at Happy Isles. Similar disproportionate volumetric relations (between precipitation and overflowing water tanks) occur upslope from the Curry Village rock-fall source area. Field calibrated analyses of satellite imagery indicate that melting snow was present in Staircase Creek watershed during the late spring, but seepage observations show that melting snow or tank overflow in the Staircase Creek watershed does not reach the rock-fall source area. Because of its proximity, precipitation on the upper cliffs moving down slope through unsaturated fractures is the likely source of most seepage at the rock-fall source area. Purported correlations between tank overflows and rock falls disappear when all data are evaluated. We conclude that these Glacier Point rock falls, like the hundreds of documented rock falls in Yosemite Valley, were naturally occurring events.

High-resolution photography, video, and laser scanning data reveal the mechanics behind a three-week-long series of rock falls from the Rhombus Wall in Yosemite Valley, California. The initial rock fall occurred at approximately 05:15 PDT on 26 August 2009, and took the form of a small ( approximately 3 m (super 3) ) rock burst centered at the tip of an overhanging rock slab, a point of stress concentration. Several hours later, beginning at approximately 13:30 PDT, a series of three rock falls, separated in time by 20-40 seconds, detached from the upper northwest corner of the same area. The failures progressed upward along near-vertical sheeting joint behind the overhanging slab. Analysis of high definition video indicates that sudden shear failure occurred along the sheeting joint with associated tensile failure within the rock slab. At 14:09 PDT, a much larger rock fall occurred from the lower portion of the overhanging slab. Rock debris traveled to the base of the talus slope and damaged unoccupied vehicles in the Ahwahnee Hotel parking lot. Another smaller rock fall occurred from the upper portion of the overhanging slab at 15:35 PDT. The cumulative volume of the 26 August rock falls was 740 m (super 3) as revealed by difference analysis of airborne and terrestrial LiDAR data. LiDAR analysis also revealed that between 380 and 1600 m (super 3) of additional rock could be released in the event of subsequent failure of the remaining slabs located above the source area. Over the next three weeks, audible cracking sounds were heard on at least four occasions from the Rhombus Wall, suggesting punctuated incremental crack growth within or near these slabs. Visual monitoring of the rock-fall source area during this time indicated that the aperture of a new sheeting joint formed between the upper cliff surface and lower detachment surface widened, suggesting that the fracture was propagating upward behind the cliff face. At 18:12 PDT on 14 September 2009 a rock fall, whose location and volume (110 m (super 3) ) were defined by terrestrial LiDAR analysis, detached along this sheeting joint, concluding the rock-fall series. Detailed documentation and analysis of these rock falls provides valuable empirical evidence that furthers our understanding of progressive sheeting joint-type failures.

AN - 902076136; 2011-093403 AB - John Day Fossil Beds National Monument (JODA) is located in eastern Oregon and is comprised of the Clarno, Painted Hills, and Sheep Rock Units. The park was established in 1975 for its superb fossil resources spanning nearly 40 million years of the Cenozoic from the early Eocene to the late Miocene. Fossils preserved at JODA include a diverse array of vertebrate, invertebrate, plant, and trace fossils. The wide variety of rock types at JODA provide ample resources for research projects focusing on tuffs, lava flows, or sedimentary and volcaniclastic rocks from a range of environments. The Thomas Condon Paleontology Center at the Sheep Rock Unit is home to an active research program with museum collections and lab facilities, as well as education programs and hundreds of fossils on display for the public. JODA recently became involved in the GeoCorps program in cooperation with the Geological Society of America and hosted two GeoCorps researchers for the summer season of 2010. Their research projects focused on the geochemistry of the tuffs in the John Day Formation and the ecological niche distribution of mammals from the Mascall fauna during the mid-Miocene climatic optimum. Projects like these are valuable contributions, adding to the understanding of the park's resources. The education and outreach programs at JODA provide opportunities for school classes to take field trips to the monument, classroom activities for teachers, and ranger programs for the public. Field trips give students insight into fossil discovery, as well as the lab and curation work necessary to put fossils on display at a museum. Fossil kits and other educational materials are available for loan to teachers for use in their classrooms. Ranger led activities include hikes and night sky programs. These resources make JODA a great venue for addressing research questions relating to Cenozoic fossils, volcanism, and other geologic processes. Future projects will hopefully involve detailed geologic mapping of the Sheep Rock Unit and development of a multidisciplinary GIS database.

We present soils data from two areas, 1) the Cache Creek Natural Area (CCNA), east of Clear Lake in Lake County, approximately 220km SSE of the triple junction region, and 2) the Confusion Hill area along Highway 101 in Mendocino County, approximately 60km SE of the triple junction region. In the CCNA, we find from the soils data and valley geomorphology, that river incision has occurred for at least the past 200,000 + or - 100,000 years. The style of incision appears to be episodic, with incision events or episodes separated by intervals of stability and valley widening. Flights of 4-9 river terraces are preserved over a time span of perhaps 0.1 million years in the CCNA. The average rate of uplift estimated by the relative ages of river terraces based upon soil development is approximately 1 meter/ka, varying between about 0.26 m /ka to more than 1m/ka for the oldest surfaces. In the Confusion Hill area, we see the same episodic incision over approximately the same time span, but the rate of incision is significantly higher and appears to have recently accelerated. Since about 40,000 years ago, the uplift rate is as high as 4m/ka. This high rate of incision is undoubtedly due to the bulge of uplift surrounding the triple junction, a tectonic/geomorphic signature corroborated by previous researchers. In both locations we believe incision has occurred over a much longer time interval (perhaps as much as a million years), but here we only report on the time interval spanned by our soils studies. In both regions, there are older surfaces (estimated to be 10 (super 5) years in age) with soils that have well developed Bt horizons (A/Bw/Bt/Cox/Cn profiles), whereas the younger surfaces have soils with Bw horizons (A/Bw/Cox/Cn profiles. The clay percentages of the older soils are substantially greater (e.g. 46% vs 14%), and all profile development indices yield numerical values suggesting an order of magnitude difference in soil ages. In lieu of numerical ages we find the relative age estimates provided by soil chronosequences to be an excellent proxy for an understanding of geologic rates in this tectonic setting.

Without an understanding of storage properties, water sources, and discharge parameters of the system, it is difficult, at best, to determine how these systems will react to environmental change. The highly karstified nature of marble within Sequoia and Kings Canyon National Parks provide opportunities to document the change in water chemistry along a transect from the upstream sinks through multiple sections of a karst aquifer to the downstream spring of the system. This allows for quantification of the amount and location of diffuse flow into conduit systems from primary and secondary porosity of the aquifer. Two karst systems within these parks were sampled to document downstream variations in water quantity and quality: the Tufa Springs system provided an example of alpine karst fed primarily by seasonal snowmelt and the Big Springs system provided insight into a mid-elevation system fed both by snowmelt and rainfall. In both systems discharge increased as infeeders and diffuse flow entered the conduits. The chemical variations provided a more complex view of the systems. Specific conductance, temperature, pH, and dissolved ion concentrations did not necessarily change relative to the length of conduit traveled. Instead these changes appear to be related to input of water from diffuse sources. In the Tufa Karst system this is seen by comparing two aquifer segments. In the upstream most aquifer segment, conductivity increases from 8 mS/cm to 20 mS/cm along a length of approximately 1000 m. This segment has only a small increase in discharge, indicating minimal diffuse input. The next segment shows a conductivity increase from 21mS/cm to 70mS/cm over a length of 1800m. Sinking stream input into the downstream spring of this segment only accounts for 65% of the total discharge of the spring, indicating a significant diffuse input into the system. A similar pattern is seen in the Big Springs karst, where water enters the system with a conductivity of 35mS/cm and exits the system with a conductivity of 136mS/cm with a similar amount of water entering the conduit as diffuse flow.

The Jamaica Bay portion of Gateway National Recreation Area, located next to highly urbanized New York City, faces many challenges to preserve and protect its natural, cultural, and recreational resources. To aid in the management of the park resources, detailed estuarine shoreline analyses of Jamaica Bay have been undertaken using air photos taken in 1924, 1951, 1974, and 2006. A 16 class land use/land cover scheme was created after doing an initial examination of the types of land cover in the 2006 air photos and then consistently applied in the analyses of the other years. By quantifying how and where the shoreline has changed over the past 85 years, park managers will have a better understanding of shoreline changes within and outside of the park boundaries as well as before and after the park was created in 1972. A comparison of each quarter-century period shows the effects of heavily increased urbanization, while indicating the effectiveness of the park's management and providing insights on ways to better restore and protect its natural resources. Despite the heavy development of New York City, the shoreline of Jamaica Bay within and outside the park has maintained large percentages of vegetation and sandy beaches.

To provide the National Park Service with geologic-hazard information for future park management, the Utah Geological Survey conducted a geologic-hazard investigation of a portion of ZNP. The ZNP Geologic-Hazard Study Area is a 154-square-mile area that encompasses Zion Canyon, Kolob Canyons and Kolob Terrace, the Zion-Mount Carmel Highway corridor, and all currently developed and high-use areas of the park. Results of this investigation include nine 1:24,000-scale GIS-based geologic-hazard maps that cover flooding and debris flows, rock fall, landslides, surface faulting, liquefaction, collapsible soil, expansive soil and rock, gypsiferous soil and rock, and soil piping and erosion. Accompanying text documents describe the hazards and provide background information on data sources, the nature and distribution of the hazards, and possible hazard-reduction measures. The text documents also include a discussion of earthquake-induced ground shaking, but data were insufficient to prepare a ground-shaking-hazard map. The maps are intended for general planning use to indicate where site-specific geologic-hazard investigations are necessary. Site-specific investigations can resolve uncertainties inherent in the 1:24,000-scale maps, and help increase safety by identifying the need for special engineering design or hazard mitigation. The most widespread geologic hazard in ZNP is flooding. Eight individuals lost their lives between 1950 and 2008 due to flooding, and floods and debris flows have repeatedly damaged park facilities. Rock falls have resulted in three deaths and property damage in the park. Landslides are common where clay-rich bedrock crops out on slopes, and have damaged park transportation corridors and dammed streams. Collapsible soil is the most prevalent soil-related geologic hazard and at least one park building has sustained significant damage due to soil collapse. Large earthquakes are rare events in southwestern Utah, but earthquakes have the greatest potential for causing catastrophic property damage and loss of life. Faults in the region are capable of producing earthquakes of magnitude 6.5-7.0.

The PMF is a hypothetical, deterministic, maximum flood with no associated probability. Modifying all of these dams for the PMF would potentially cost the taxpayers billions of dollars. Based on observations of flood plain soils and geomorphology, it was clear that there had not been floods equivalent to the magnitude of the PMF in the Holocene. To test the hypothesis that the PMF had a very low probability, mapped inundation limits of the PMF were compared to terrace chronologies. The results showed that the probability of the PMF was very small relative to other natural hazards such as earthquakes, volcanic eruptions, and meteorite impacts. In fact, floods with a probability of 1 in 10,000 have peak discharges that are only 10% to 30% of the hypothetical PMF. The identification of this inequity in natural hazard assessment eventually helped lead Reclamation to the use of risk analysis in dam safety to more accurately portray the hazards and risk from floods and earthquakes. With the aid of advances in hydraulic modeling, radiocarbon analysis, and statistical methods, it soon became clear that soils developed on stable geomorphic surfaces could establish limits on the peak discharge of floods through the Holocene. This insight led to the formulation of the concept of paleohydrologic bounds, which is a time interval during which a particular discharge has not been exceeded. The primary indicator of this bound is evidence for surface stability as recorded by soils developed on terrace alluvium. In this way, soil stratigraphy and geomorphology form the basis for understanding flood behavior throughout the West. These basic observations of landscape stability can then be quantified through the use of two-dimensional hydraulic models, radiocarbon ages, and flood frequency analysis capable of properly considering non-exceedance information. This basic application of soils and geomorphology has revolutionized the understanding of extreme flood behavior in the Western U.S. The application of this knowledge to dam safety issues at Reclamation has probably saved the taxpayers of the U.S. more than a billion dollars.

Water quality is an important issue. The Colorado River serves about 7.5 million people in the basin, and through export, the river provides full or supplemental water supply to another 25.4 million people outside the basin. Salt loading from public lands in tributary watersheds feeding the Colorado River originates primarily from Paleozoic and Mesozoic Era sedimentary rocks, which are comprised of different mineral assemblages of sodium-calcium-magnesium sulfates and chlorides with gypsum being one of the dominant minerals. A methodology was created to determine how the salts travel (i.e., major transit source) to the perennial surface water. The study investigated whether salt loading occurred primarily by a surface-runoff process or by a ground-water inflow to-the-stream process. Field data collection included both spatial and temporal measures that focused on the parameters for salt-contributing geologic formations; location, extent, permeability and salinity concentration of soils; geomorphic structures and topographical gradient; ground-water quality and gradient; surface-water quality and discharge, and meteorologic data. Data analysis included exploratory statistical techniques, water quality assessment, and geographic information system (GIS) analysis of salinity source and transport through the display, integration, and geostatistical interpretation of the different parameter map layers. Land managers with knowledge of the salt loading mode in a watershed can more effectively plan and expend to minimize water-quality degradation from public lands. For the study watershed, the San Rafael River, there is evidence of a ground-water inflow to-the-stream process that is occurring during snow melt season and a surface-runoff process during late summer.

Over the past three years, we have collected continuous hydrologic data from two caves in different hydrogeologic regimes to examine relationships between precipitation, drip response, climate, vegetation, and epikarst properties. At James Cave (VA), bedrock has low matrix storage and epikarst is covered by 1-2m of residuum. Permeability and storage are primarily in solutionally enlarged fractures and bedding planes, with soils and residuum contributing to baseflow. At Cave Without A Name (CWAN; TX), bedrock is covered by thin or no soil, and permeability and storage are primarily found in matrix porosity and enlarged fractures and bedding planes. Discharge data from drip sites in each cave reveal differences and similarities in the hydrologic functioning of epikarst. In James Cave, drips at three sites respond to precipitation events only after sufficient precipitation during late winter and early spring, with subsequent rapid responses in quickflow (peaking at 5 to 30 L/hr), and corresponding increases in baseflow ( approximately 0 to 1 L/hr). Baseflow recession analyses indicate that epikarst contributions support baseflow in the nearby cave stream during the summer months. Baseflow levels depend on receiving sufficient precipitation during the previous fall and winter. At CWAN, however, drip responses at five sites are primarily related to periods with above average precipitation, with less connection to season and more dependence on El Nino and La Nina climate patterns. Three drip sites responded quickly to repeated rain events after a 2-year drought when most drip sites were essentially dry. After a large rain event and rapid drip initiation, two of these (>10 L/hr) cease to drip after 2-4 weeks, while the third site increased from approximately 80 ml/hr to approximately 1500 ml/hr and now maintains this drip rate. The other two sites showed no response to precipitation and continue to drip at essentially the same rate ( approximately 5-10 ml/hr). Results thus far support a complex conceptual model of flow and storage in the epikarst where physical and hydrologic properties, in combination with climatic conditions, determine how epikarst regulates recharge to the underlying aquifer.

Through a cooperative agreement, NPS Geologic Resources Division geologists work along-side geologists from Colorado State University to compile and produce high quality, informative digital geologic maps and reports, and to also devise ways to increase the accessibility and overall utility of geospatial data. Recently, the GRI team designed and began production of geologic map layouts that accompany a geologic report, providing an overview of the digital geologic data available for a specific park. These layouts, provided as a paper hard copy and electronically in Adobe PDF format, are produced using Environmental Research Systems Institute (ESRI) ArcGIS 9.3 software. These maps display typical cartographic elements such as legends, scale bars, north arrows, as wells as utilize hillshading and geographic features, such as roads, political boundaries, and relevant structures. Both GIS and non-GIS users can benefit from these layouts as they provide an overview of the data contained within the digital GIS dataset, allowing them to easily determine how to best integrate this geologic GIS information into the science-based natural resource stewardship mission of the NPS.

Five trenches were excavated as part of a study examining geomorphic controls on the distribution of shrubland and grassland ecosystems. Trench logs, surficial deposit and soil descriptions, and physical property measurements were made to characterize exposed deposits that included loess, reworked loess, sheetwash, and fluvial-channel fill all of which contain weak to moderate textural B horizons and Stage I-III carbonate horizons. In addition, optically stimulated luminescence (OSL) ages and one (super 14) C age were determined. The loess deposits consist of two previously unrecognized units, totaling about 2 meters thick. The lower loess unit was deposited between about 10,500 yr B.P. and 7,500 yr B.P. A short hiatus after the deposition of this unit is represented by soil development that included formation of abundant clay films and moderate structure. The upper unit was deposited between about 6,000 yr B.P. and <1,400 yr B.P. and consists of alternating beds of loess, re-deposited loess, and sheetwash deposits. The timing and stratigraphy of these two units in the Hatch Point-Canyon Rims area are consistent with OSL ages of Holocene dune mobilization and alluvial activity determined from previous work 30 km to the west in Canyonlands National Park. Deposition of the lower loess unit in the Canyon Rims-Hatch Point trenches corresponds to a time of dune activity in the Canyonlands area. Deposition of the upper loess, re-deposited loess, and sheetwash deposits corresponds to a time of alternating alluvial and dune activity in the Canyonlands area.

Addressing quantitatively how glaciers will respond to present and future climate change demands that we understand how small alpine glaciers have responded to past climate change. Previous research suggests that small alpine glaciers often respond to climate changes by retreating into topographic niches, where they receive less direct solar radiation and can be maintained by high snow fluxes associated with avalanching and headwall protection. We report preliminary results from a project targeting the Lyell and Maclure Glaciers in Yosemite National Park. We aim to understand their response to climate change through and subsequent to the Little Ice Age by combining archival records of glacier position through time, instrumental records augmented by new instrumentation, and analysis of new local tree-ring records. Using the instrumental record and tree cores, we calibrate tree ring width with instrumental records for the area, verifying the correlation between tree ring growth and climate variations on a local level. Tree ring records near Lyell and Maclure Glaciers expand the record into the Little Ice Age (covering at least 300 years) in the context of the glaciers' local climate. For further resolution, we use the photo and map archival record for the glaciers to evaluate and calibrate past size changes with instrumental and tree ring records. The work strengthens the correlation between high alpine tree growth and instrumental records allowing a more accurate look into climate patterns extending beyond instrumental records for the recent past. For the Lyell and Maclure Glaciers, our data provide a detailed picture of how these glaciers have responded to previous changes in localized climate and indicate what would be reasonable to expect in terms of future retreat rates and magnitudes.

Fossils from the site attracted the attention of scientists beginning with the Hayden Survey during the 1870s. Florissant became widely known from the published works of paleontologists Leo Lesquereux, Samuel Scudder, and E. D. Cope as they described hundreds of new species of fossil plants, insects, spiders, and vertebrates during the 1870s to 1900. Many other paleontologists followed during the twentieth century, notably T. D. A. Cockerell and Harry D. MacGinitie. These combined works ultimately resulted in the description of more than 1700 fossil species, documenting Florissant as one of the world's taxonomically most diverse fossil sites. Many of the type specimens of the first-described fossils were collected by an early homesteader, Charlotte Hill, who lived at the site and contributed to the scientific discovery by providing specimens to Scudder and Lesquereux. The first geologic map of Florissant was prepared in 1878 by pioneering Colorado geologist Arthur Lakes, who was an early member of the Colorado Scientific Society (CSS). Exactly a century later another CSS member, Rudy Epis, coauthored the published USGS geologic map of Florissant. Ongoing research about paleontology, geology, and history of science at Florissant is supported by an active paleontology program, and contributors to this effort include interns as well as current CSS members such as Emmett Evanoff, Beth Simmons, and Libby Prueher. Florissant's fossils became attractions for commercial tourism by the late 1800s and the focal point for the establishment of a national monument in the 1960s. The controversial effort to create the monument involved scientists such as Estella Leopold who stepped forward as activists, and along with their lawyers they helped to prompt the innovative legal strategies that laid the groundwork for subsequent environmental conservation in the state. This combination of science, tourism, and conservation makes Florissant a landmark in the history of Colorado.

The mechanism, where solar radiation and temperature variation drives deformation of partially detached rock flakes, has been postulated for some rock falls, but has yet to be adequately quantified. For example, in Yosemite Valley, California, rock falls have occurred on hot summer days in the absence of any meteorologic, seismic, or other recognized trigger, but the late afternoon timing of the majority of events, when rock temperatures are maximum suggest that thermally driven rock flexure may be the cause. However, little is known about the magnitude of rock deformation during thermal stressing or whether this is sufficient for crack propagation. To address these questions, we are monitoring the deformation of a near-vertical granitic rock flake in Yosemite Valley. The flake, 14 m tall, 4 m wide and 12 cm thick, faces south and receives direct sunlight. Whereas the flake is attached to the cliff face at its bottom and top, the sides are detached from the cliff by a 10 cm wide crack on one side, tapering to a 1 cm wide crack on the opposite side. Instrumentation consists of three custom-designed crackmeters placed between the flake and the adjacent cliff face, three air temperature sensors located behind the flake, and three dual air temperature-solar radiation sensors located on the outside surface of the flake. Five-minute interval data from summer 2010 indicates the flake undergoes maximum deformation at mid-span between attachment points and that it deforms from both diurnal and climatic temperature fluctuations. Recorded maximum deformations are 1 cm diurnally and nearly 1.5 cm (including diurnal effect) over a 5-day period of cooler temperatures. Diurnal fluctuations reach peak contraction (crack closing) in mid-morning, synchronous with low solar radiation and air temperature, and peak expansion (crack opening) in late-afternoon when temperatures are maximum. These measurements demonstrate that thermally driven rock flexure is capable of deforming large rock slabs. Cumulative outward deformation with moment-inducing tensile stresses and crack tip propagation may also be occurring in this and other partially detached rock flakes in Yosemite Valley, thereby providing a potential trigger for many rock falls.

The Dinero mine tunnel is an approximately mile-long tunnel that drained the deposits and facilitated ore transport to the surface during mining. More recently, however, drainage from the Dinero tunnel was identified as a major contributor of zinc and manganese loads to the Lake Fork of the Arkansas River. Consequently the Bureau of Land Management and Colorado Division of Reclamation, Mining, and Safety remediated the tunnel by installing a structural bulkhead that was sealed in October 2009. Prior to bulkhead installation (2006), seasonal monitoring of discharge and water quality occurred at all drainage features and streams within about a 1-mile radius of the Dinero tunnel. All previously sampled locations and any new drainage features created following bulkhead closure will be sampled for 3 years (2010-2012) to quantify changes in discharge and water quality resulting from bulkhead closure. Comparison of pre-bulkhead water-quality data (pH, specific conductance, alkalinity, major and trace element concentrations, and stable isotopes) between sites grouped as mining features, seeps, springs, and streams indicated that stable isotope ratios (deuterium and oxygen in water) are the most useful measures for discriminating between sample groups affected by mine drainage. The Dinero tunnel water is the most isotopically depleted of all samples collected in the area and presumably represents deeper, older groundwater compared to other samples. Thus, post-bulkhead shifts to more depleted isotopic values at other sample sites may indicate migration of Dinero tunnel water to those sites. Results will help assess not only changes caused by bulkhead emplacement, but also may demonstrate the utility of detailed pre-and post-bulkhead water-quality sampling to evaluate similar sites.

However, presence-absence data arising from auditory detections may be more prone to observation error (e.g., false-positive detections) than are sampling approaches utilizing physical captures or sightings of individuals. We conducted realistic, replicated field experiments using a remote broadcasting system to simulate simple anuran call surveys and to investigate potential factors affecting observation error in these studies. Distance, time, ambient noise, and observer abilities were the most important factors explaining false-negative detections. Distance and observer ability were the best overall predictors of false-positive errors, but ambient noise and competing species also affected error rates for some species. False-positive errors made up 5% of all positive detections, with individual observers exhibiting false-positive rates between 0.5% and 14%. Previous research suggests false-positive errors of these magnitudes would induce substantial positive biases in standard estimators of species occurrence, and we recommend practices to mitigate for false positives when developing occupancy monitoring protocols that rely on auditory detections. These recommendations include additional observer training, limiting the number of target species, and establishing distance and ambient noise thresholds during surveys.

An important concern in the Basin is the fate of the large amounts of groundwater extracted during production of coal-bed natural gas (CBNG). Most of the produced water is disposed of in unlined surface impoundments. A six-year study of groundwater flow and water chemistry at one impoundment, Skewed Reservoir, has produced the most detailed data set for any impoundment in the basin. Data were collected from a network of 21 observation wells and 3 suction lysimeters. A groundwater mound formed atop bedrock within initially unsaturated, unconsolidated deposits underlying the reservoir. Heterogeneity in physical and chemical properties of sediments resulted in complex groundwater-flow paths and highly variable groundwater chemistry. Sulfate, bicarbonate, sodium, and magnesium were the dominant ions in all locations, but substantial spatial variability existed in relative concentrations; pH varied from less than 3 to more than 9, and total dissolved solids concentrations ranged from less than 5,000 to greater than 100,000 mg/L. Selenium was a useful tracer of reservoir water; selenium concentrations exceeded 300 mg/L in groundwater samples obtained from 18 of the 24 sampling points. Groundwater travel time from the reservoir to a nearby alluvial aquifer (a linear distance of 177 m) was calculated at 474 days on the basis of selenium concentrations. The CBNG produced water is not the primary source of selenium or other solutes in the groundwater. Naturally occurring salts and minerals within the unsaturated zone, dissolved and mobilized by infiltrating impoundment water, account for most of the solute mass in groundwater. Gypsum dissolution, cation exchange, and pyrite oxidation appear to be important reactions.

Given the challenges of having limited guidance on preferred incorporation methods, and given the reality of typically having access to only a limited pool of planning practitioners trained in the application of such methods, the Bureau of Reclamation has initiated numerous efforts to address "planning capacity" in the context of internal program and planning needs. The focus here is on two types of vehicles that have underpinned much of these activities and led to successes in capacity-building, namely: practitioner networks and science-management partnerships. The presentation introduces four example coalitions that have involved Reclamation, highlighting how these coalitions have helped build planning capacity and challenges that have been experienced: (1) "Climate Change and Water Working Group," an interagency group co-developing user needs documents (Circular 1331), collaborative R&D strategies, training curricula for practitioners and a workshop to develop methods guidelines for water planning practitioners, (2) "Bias Correction and Spatially Downscaled WCRP CMIP3 Climate Projections," an interagency-NGO-academic partnership working to develop and provide downscaled climate projection information for the contiguous United States, (3) "Colorado River Basin Hydrology Work Group", a academic-public-private sector group working to pilot and select methods to serve various environmental compliance and general study efforts in the basin, (4) Columbia-Snake Basin "Reservoir Management Joint Operating Committee," sponsoring a intergovernmental-NGO-academic technical group that is working to adopt a consensus set of future hydroclimate scenarios and methods for use in basin planning efforts.

Nest predation is the major cause of nest failure in passerines, and nesting success for some shortgrass prairie birds is exceptionally low. The 3 primary land uses in the central shortgrass prairie ecoregion are native shortgrass prairie rangeland (62%), irrigated and nonirrigated cropland (29%), and Conservation Reserve Program (CRP, 8%). Because shortgrass-cropland edges and CRP may alter the community of small mammal predators of grassland bird nests, I sampled multiple sites on and near the Pawnee National Grasslands in northeast Colorado, USA, to evaluate 1) whether small mammal species richness and densities were greater in CRP fields and shortgrass prairie-cropland edges compared to shortgrass prairie habitats, and 2) whether daily survival probabilities of ground-nesting grassland bird nests were negatively correlated with densities of small mammals. Small mammal species richness and densities, estimated using trapping webs, were generally greater along edges and on CRP sites compared to shortgrass sites. Vegetation did not differ among edges and shortgrass sites but did differ among CRP and shortgrass sites. Daily survival probabilities of artificial nests at edge and CRP sites and natural nests at edge sites did not differ from shortgrass sites, and for natural nests small mammal densities did not affect nest survival. However, estimated daily survival probability of artificial nests was inversely proportional to thirteen-lined ground squirrel (Spermophilus tridecemlineatus) densities. In conclusion, these data suggest that although land-use patterns on the shortgrass prairie area in my study have substantial effects on the small mammal community, insufficient data existed to determine whether land-use patterns or small mammal density were affecting grassland bird nest survival. These findings will be useful to managers for predicting the effects of land-use changes in the shortgrass prairie on small mammal communities and avian nest success.

The chronic criterion accumulation ratio (CCAR), a modification of biotic ligand model (BLM) outputs for use as a toxic-unit model, accounts for the modifying and competitive influences of major cations (Ca super(2+), Mg super(2+), Na super(+), K super(+), H super(+)), anions (HCO, Cl super(-), S super(2-)) and dissolved organic carbon (DOC) in determining the free metal ion available for accumulation on the biotic ligand. The cumulative criterion unit (CCU) model, an empirical statistical model of trace-metal toxicity, considers only the ameliorative properties of Ca super(2+) and Mg super(2+) (hardness) in determining the toxicity of total dissolved trace metals. Differences in the contribution of a metal (e.g., Cu, Cd, Zn) to toxic units as determined by CCAR or CCU were observed and attributed to how each model incorporates the influences of DOC, pH, and alkalinity. Akaike information criteria demonstrate that CCAR is an improved predictor of benthic macroinvertebrate community metrics as compared with CCU. Piecewise models depict great declines (thresholds) in benthic macroinvertebrate communities at CCAR of 1 or more, while negative changes in benthic communities were detected at a CCAR of less than 1. We observed a 7% reduction in total taxa richness and a 43% decrease in Heptageniid abundance between background (CCAR = 0.1) and the threshold of chronic toxicity on the basis of continuous chronic criteria (CCAR = 1). In this first application of the BLM as a toxic-unit model, we found it superior to CCU.

The shore crabs, Hemigrapsus oregonensis and Pachygrapsus crassipes, are abundant in estuaries and beaches throughout northern California, USA and have been used as indicators of habitat conditions in several salt marshes. The overall objectives of the present study were to conduct a lab-based study to test the accumulation of current-use pesticides, validate the analytical method and to analyze field-collected crabs for a suite of 74 current-use and legacy pesticides. A simple laboratory uptake study was designed to determine if embryos could bioconcentrate the herbicide molinate over a 7-d period. At the end of the experiment, embryos were removed from the crabs and analyzed by gas chromatography/mass spectrometry. Although relatively hydrophilic (log K sub(OW) of 2.9), molinate did accumulate with an estimated bioconcentration factor (log BCF) of approximately 2.5. Following method validation, embryos were collected from two different Northern California salt marshes and analyzed. In field-collected embryos 18 current-use and eight organochlorine pesticides were detected including synthetic pyrethroids and organophosphate insecticides, as well as DDT and its degradates. Lipid-normalized concentrations of the pesticides detected in the field-collected crab embryos ranged from 0.1 to 4 ppm. Pesticide concentrations and profiles in crab embryos were site specific and could be correlated to differences in land-use practices. These preliminary results indicate that embryos are an effective sink for organic contaminants in the environment and have the potential to be good indicators of ecosystem health, especially when contaminant body burden analyses are paired with reproductive impairment assays.

However, the performance of adaptive designs has not been investigated when outcomes are not only rare and clustered but also imperfectly detected. We address this combination of challenges using data simulated to mimic properties of freshwater mussels from a reach of the upper Mississippi River. Simulations were conducted under a range of sample sizes and detection probabilities. Under perfect detection, efficiency of the adaptive sampling design increased relative to the conventional design as sample size increased and as density decreased. Also, the probability of sampling occupied habitat was four times higher for adaptive than conventional sampling of the lowest density population examined. However, imperfect detection resulted in substantial biases in sample means and variances under both adaptive sampling and conventional designs. The efficiency of adaptive sampling declined with decreasing detectability. Also, the probability of encountering an occupied unit during adaptive sampling, relative to conventional sampling declined with decreasing detectability. Thus, the potential gains in the application of adaptive sampling to rare and clustered populations relative to conventional sampling are reduced when detection is imperfect. The results highlight the need to increase or estimate detection to improve performance of conventional and adaptive sampling designs.

B.S.P.) forest stands range from well drained to poorly drained, typically contain large amounts of soil organic carbon (SOC), and are often underlain by permafrost. To better understand the role of soil drainage class in carbon dioxide (CO sub(2)) exchange and decomposition, we measured soil respiration and net CO sub(2) fluxes, litter decomposition and litterfall rates, and SOC stocks above permafrost in three Alaska black spruce forest stands characterized as well drained (WD), moderately drained (MD), and poorly drained (PD). Soil respiration and net CO sub(2) fluxes were not significantly different among sites, although the relation between soil respiration rate and temperature varied with site (Q sub(10): WD > MD > PD). Annual estimated soil respiration, litter decomposition, and groundcover photosynthesis were greatest at PD. These results suggest that soil temperature and moisture conditions in shallow organic horizon soils at PD were more favorable for decomposition compared with the better drained sites. SOC stocks, however, increase from WD to MD to PD such that surface decomposition and C storage are diametric. Greater groundcover vegetation productivity, protection of deep SOC by permafrost and anoxic conditions, and differences in fire return interval and (or) severity at PD counteract the relatively high near-surface decomposition rates, resulting in high net C accumulation.Original Abstract: Les peuplements d'epinette noire (Picea mariana (Mill.) B.S.P.) sont etablis sur des stations variant de bien a mal drainee, dont le sol contient typiquement une grande quantite de carbone organique et qui reposent souvent sur une couche de pergelisol. Pour mieux comprendre le role de la classe de drainage sur les echanges de dioxyde de carbone (CO sub(2)) et sur la decomposition, nous avons mesure les flux de respiration du sol et de CO sub(2) net, les taux de decomposition et de deposition de la litiere, et les stocks de carbone organique du sol (COS) au-dessus de la couche de pergelisol dans trois peuplements d'epinette noire de l'Alaska correspondant a des stations bien (BD), relativement (RD) et mal drainees (MD). Les flux de respiration du sol et de CO sub(2) net n'etaient pas significativement differents entre les stations, bien que la relation entre le taux de respiration du sol et la temperature variat d'une station a l'autre (Q sub(10) : BD > RD > MD). La respiration estimee du sol, la decomposition de la litiere et la photosynthese du couvert vegetal au sol avaient des valeurs annuelles plus elevees sur la station MD. Ces resultats indiquent que la temperature du sol et l'humidite des horizons organiques minces du sol de la station MD sont plus favorables a la decomposition comparativement aux stations mieux drainees. Cependant, les stocks de COS augmentaient en passant de la station BD a la station RD et de la station RD a la station MD, de sorte que la decomposition de la litiere et l'entreposage du C sont diametralement opposes. Une plus grande productivite du couvert vegetal au sol, une protection du COS en profondeur par le pergelisol et par les conditions anoxiques, ainsi que des differences dans l'intervalle entre les feux ou la severite des feux sur la station MD contrebalancent le taux relativement eleve de decomposition pres de la surface, ce qui produit une forte accumulation nette de C.

Streambed sediments in two Inner Coastal Plain streams (Crosswicks and Raccoon Creeks) that traverse these glauconitic deposits are enriched in arsenic (15-25mg/kg), and groundwater discharging to the streams contains elevated levels of arsenic (>80I14g/L at a site on Crosswicks Creek) with arsenite generally the dominant species. Low dissolved oxygen, low or undetectable levels of nitrate and sulfate, detectable sulfide concentrations, and high concentrations of iron and dissolved organic carbon (DOC) in the groundwater indicate that reducing environments are present beneath the streambeds and that microbial activity, fueled by the DOC, is involved in releasing arsenic and iron from the geologic materials. In groundwater with the highest arsenic concentrations at Crosswicks Creek, arsenic respiratory reductase gene (arrA) indicated the presence of arsenic-reducing microbes. From extracted DNA, 16s rRNA gene sequences indicate the microbial community may include arsenic-reducing bacteria that have not yet been described. Once in the stream, iron is oxidized and precipitates as hydroxide coatings on the sediments. Arsenite also is oxidized and co-precipitates with or is sorbed to the iron hydroxides. Consequently, dissolved arsenic concentrations are lower in streamwater than in the groundwater, but the arsenic contributed by groundwater becomes part of the arsenic load in the stream when sediments are suspended during high flow. A strong positive relation between concentrations of arsenic and DOC in the groundwater samples indicates that any process--natural or anthropogenic--that increases the organic carbon concentration in the groundwater could stimulate microbial activity and thus increase the amount of arsenic that is released from the geologic materials.

Seep sediments also contain smaller macrofaunal invertebrates whose nutritional pathways are not well understood. Using stable-isotope analysis, we investigate the utilization of chemosynthetically fixed and methane-derived organic matter by macrofauna. Biological sampling was conducted in three lower-slope GOM seep environs: Green Canyon (GC852, 1428m), Atwater Valley (AT340, 2230m), and Alaminos Canyon (AC601, 2384m). Infaunal delta 13C and delta 15N exhibited a broad range of values; most infauna appeared to be heterotrophic, although several taxa had very light delta 15N and delta 13C values, indicating possible reliance on chemoautotrophic symbioses. The lightest delta 13C and delta 15N values were observed in nematodes ( delta 13C=54.6 plus or minus 0.1 delta 15N=6.1 plus or minus 0.2 76; ) and one gastropod ( delta 13C=54.1 delta 15N=1.1) from Green Canyon. Mixing-model results indicated that sulfur-oxidizing Beggiatoa may be an important food source for seep infauna; the rate of utilization ranged from 60% to 100% at Green Canyon and Atwater Valley. The overall range in isotope values was similar across the three sites, suggesting that biogeochemical processes may be very similar in these geographically distinct areas.

Few studies have detailed activity patterns where the species are sympatric and no studies contrasted patterns where populations are both sympatric and allopatric. We contrasted activity patterns for sympatric black and grizzly bears and for black bears allopatric to grizzly bears, how human influences altered patterns, and rates of grizzly-black bear predation. Activity patterns differed between black bear populations, with those sympatric to grizzly bears more day-active. Activity patterns of black bears allopatric with grizzly bears were similar to those of female grizzly bears; both were crepuscular and day-active. Male grizzly bears were crepuscular and night-active. Both species were more night-active and less day-active when less than or equal to 1km from roads or developments. In our sympatric study area, 2 of 4 black bear mortalities were due to grizzly bear predation. Our results suggested patterns of activity that allowed for intra- and inter-species avoidance. National park management often results in convergence of locally high human densities in quality bear habitat. Our data provide additional understanding into how bears alter their activity patterns in response to other bears and humans and should help park managers minimize undesirable bear-human encounters when considering needs for temporal and spatial management of humans and human developments in bear habitats.

Attempts to measure disturbance effects on shorebird habitat use and behavior at stopover sites are difficult because ORV disturbance is frequently confounded with habitat and environmental factors. We used a before-after-control-impact experimental design to isolate effects of vehicle disturbance from shorebird responses to environmental and habitat factors. We manipulated disturbance levels within beach closures along South Core Banks, North Carolina, USA, and measured changes in shorebird abundance and location, as well as the activity of one focal species, the sanderling (Calidris alba), within paired control and impact plots. We applied a discrete treatment level of one flee-response-inducing event every 10minutes on impact plots. We found that disturbance reduced total shorebird and black-bellied plover (Pluvialis squatarola) abundance and reduced relative use of microhabitat zones above the swash zone (wet sand and dry sand) by sanderlings, black-bellied plovers, willets (Tringa semipalmata), and total shorebirds. Sanderlings and total shorebirds increased use of the swash zone in response to vehicle disturbance. Disturbance reduced use of study plots by sanderlings for resting and increased sanderling activity, but we did not detect an effect of vehicle disturbance on sanderling foraging activity. We provide the first estimates of how a discrete level of disturbance affects shorebird distributions among ocean beach microhabitats. Our findings provide a standard to which managers can compare frequency and intensity of disturbance events at other shorebird stopover and roosting sites and indicate that limiting disturbance will contribute to use of a site by migratory shorebirds.

The San Joaquin Valley is located within the Central Valley of California and is one of the most productive agricultural areas in the world. Increased irrigation and pumping associated with agricultural and urban development during the last 100 years have changed the chemistry and magnitude of groundwater recharge, and increased the rate of downward groundwater movement. Strong correlations between U and bicarbonate suggest that U is leached from shallow sediments by high bicarbonate water, consistent with findings of previous work in Modesto, California. Summer irrigation of crops in agricultural areas and, to lesser extent, of landscape plants and grasses in urban areas, has increased P sub(CO2) concentrations in the soil zone and caused higher temperature and salinity of groundwater recharge. Coupled with groundwater pumping, this process, as evidenced by increasing bicarbonate concentrations in groundwater over the last 100 years, has caused shallow, young groundwater with high U concentrations to migrate to deeper parts of the groundwater system that are tapped by public-supply wells. Continued downward migration of U-affected groundwater and expansion of urban centers into agricultural areas will likely be associated with increased U concentrations in public-supply wells. The results from this study illustrate the potential long-term effects of groundwater development and irrigation-supported agriculture on water quality in arid and semiarid regions around the world.

Variance-covariance matrices, from model calibration and calculation of sensitivities, were used to generate parameter sets that account for parameter correlation and uncertainty. Constraining parameter sets to those that met acceptance criteria, which included a standard error criterion, did not appear to bias model results. Although the addition of atmospheric tracer observations and prior information produced similar changes in the extent of predicted recharge areas, prior information had the effect of increasing probabilities within the recharge area to a greater extent than atmospheric tracer observations. Uncertainty in the recharge area propagates into predictions that directly affect water quality, such as land cover in the recharge area associated with a well and the residence time associated with the well. Assessments of well vulnerability that depend on these factors should include an assessment of model parameter uncertainty. A formal simulation of parameter uncertainty can be used to delineate probabilistic recharge areas, and the results can be expressed in ways that can be useful to water-resource managers. Although no one model is the correct model, the results of multiple models can be evaluated in terms of the decision being made and the probability of a given outcome from each model.

This is driven primarily by the need to limit greenhouse gas production, principally CO (sub 2) (U.S. Senate Committee on Environment and Public Works, 2009; Intergovernmental Panel on Climate Change [IPCC], 2007), and by constraints on oil supplies. A near-complete transition to new and renewable sources is clearly necessary; however, this may take several decades to achieve. We must also use our current energy sources wisely, with regard to both effective utilization and environmental constraints. Our decisions must be considered carefully, because they will be far reaching.

This mechanism may dominate carbon (C) and nitrogen (N) cycles in arid, semi-arid and Mediterranean ecosystems. Existing biogeochemical models perform poorly for systems characterized by pulsed events. In this study, we added a rewetting factor into the DAYCENT soil biogeochemical model to better represent the drying-rewetting pulses. Based on a 4-month laboratory incubation from a parallel study, we developed a simple rewetting factor for representing the enhanced mineralization pulse by rewetting stimulation. The rewetting factor was then incorporated into DAYCENT by modifying the soil moisture factor. The DAYCENT modification significantly improved model performance in predicting soil C respiration rates in drying-rewetting treatments through the capture of rewetting pulses. The modification also improved prediction performance for net N mineralization in treatments with shorter rewetting intervals, but did not improve predictions in treatments with longer rewetting intervals. The model modifications were validated by using a laboratory incubation data set from a different field site. The modified DAYCENT predictions showed that active and slow SOM pools were major contributors to mineralization pulses while the contribution from the passive pool was minimal. The modifications we made improved model performance and should be considered in future field representations of biogeochemical processes.

However, classical models assume resource specialization in the form of distinct niches, which does not obviously apply to the broadly overlapping resource use in plant communities. Here we utilize an experimental framework based on competition theory to test whether plants partition resources via classical niche differentiation or via plasticity in resource use. We explore two alternatives: niche preemption, in which individuals respond to a superior competitor by switching to an alternative, less-used resource, and dominant plasticity, in which superior competitors exhibit high resource use plasticity and shift resource use depending on the competitive- environment. We determined competitive ability by measuring growth responses with and without neighbors over a growing season and then used super(15)N tracer techniques to measure uptake of different nitrogen (N) forms in a field setting. We show that four alpine plant species of differing competitive abilities have statistically indistinguishable uptake patterns (nitrate > ammonium > glycine) in their fundamental niche (without competitors) but differ in whether they shift these uptake patterns in their realized niche (with competitors). Competitively superior species increased their uptake of the most available N form, ammonium, when in competition with the rarer, competitively inferior species. In contrast, the competitively inferior species did not alter its N uptake pattern in competition. The existence of plasticity in resource use among the dominant species provides a mechanism that helps to explain the manner by which plant species with broadly overlapping resource use might coexist..

Such spatial capture-recapture data arise from studies based on camera trapping, DNA sampling, and other situations in which a spatial array of devices records encounters of unique individuals. We integrate an individual-based formulation of a Jolly-Seber type model with recently developed spatially explicit capture-recapture models to estimate density and demographic parameters for survival and recruitment. We adopt a Bayesian framework for inference under this model using the method of data augmentation which is implemented in the software program WinBUGS. The model was motivated by a camera trapping study of Pampas cats Leopardus colocolo from Argentina, which we present as an illustration of the model in this paper. We provide estimates of density and the first quantitative assessment of vital rates for the Pampas cat in the High Andes. The precision of these estimates is poor due likely to the sparse data set. Unlike conventional inference methods which usually rely on asymptotic arguments, Bayesian inferences are valid in arbitrary sample sizes, and thus the method is ideal for the study of rare or endangered species for which small data sets are typical.

Over the years, this program has seen numerous changes, but has always followed the basic mission of the university to educate undergraduate students. Utilizing students and the abundant paleontological resources in the region, the staff of this program developed not only a world renowned exhibit and research collection, but also provided its students with invaluable field-orientated experiences. This philosophy led to the applied learning strategy of the UW Geological Museum's Undergraduate Research Program. Developed in 1995 to educate aspiring, young paleontologists, this program provided motivated Geology and Zoology students with a unique opportunity to learn paleontology by doing actual research projects. Organized like a graduate-level study, students were required to choose a project, do background research, apply for funding, pursue field and/or laboratory research, supervise assistants, collect data, make observations, develop interpretations, synthesize the study in a formal paper, and submit abstracts for presentations at national meetings (e.g., Society of Vertebrate Paleontology and Geological Society of America). The range of projects included studies in the history of paleontology, microvertebrate and invertebrate faunas, dinosaur mass, and vertebrate ichnology. Unique to this program was the successful utilization of world-class paleontological field sites located on public lands. Localities such as the Late Jurassic Seminoe Tracksite in central Wyoming and those in the Middle Jurassic Sundance Vertebrate Ichnofaunal Province of northern Wyoming highlight both resource management and educational use. Students were encouraged to develop displays in the museum and instruct college-level field geology and paleontology classes about their research. The highly successfully program both enticed students to attend the university and provided invaluable experience for students applying to graduate schools. The UW Geological Museum began a legacy in the late 1800s to engage undergraduate students to learn paleontology by utilizing the unique natural resources of Wyoming. This legacy continued into the 21st century with the museum's innovative educational methods in the teaching of paleontology.

The problems associated with vegetation re-colonization are due to highly acidic soil conditions and adverse physical conditions associated with soil compaction and low water retention. To address the problems of unvegetated mine sites, we sought to determine the suitability of biochar as a soil remediation tool for re-vegetating abandoned mine lands in San Juan County, Colorado. Our study assessed the effects of biochar and straw compost amendments on the mobility, bioavailability, and toxicity of inorganic and organic contaminants in soils at abandoned mine sites. To examine biochar as a soil amendment, we conducted field trials to test for restoration potential, and container trials to examine specific physical and chemical properties of biochar treatments. The biochar field sites were located at elevations between 2,800 and 3,700 meters; site soils conditions ranged from pure waste rock to partially reclaimed forest soils. The field trial segment utilized a randomized block design of three blocks consisting of 2 X 1 meter plots with one seed-only control and three treatments: (1) biochar (30% by volume); (2) biochar and straw mulch; and, (3) straw mulch. The container trials, which were conducted at the Mountain Studies Institute field station, consisted of a seed emergence test, a vegetation biomass accumulation test, and a soil leachate test. Preliminary results suggest that biochar, in conjunction with organic mulch, may increase vegetative response in both rates of re-colonization and growth vigor by up to 50%. Confirmation of these results suggests that biochar, when combined with organic mulch, may be a useful tool for soil restoration at abandoned mine sites, or at other locations with severely degraded soils.

Laser scanning data allows for new analyses to investigate rock falls and assess hazards with increased accuracy and precision. We utilize both airborne and ground-based terrestrial LiDAR data to (1) investigate prehistoric rock fall frequency and magnitude, (2) document and analyze modern rock falls, (3) monitor cliff faces, and (4) assess future rock fall susceptibility and runout. Postglacial talus volumes yield annually averaged rock-fall rates that can be compared across different slope angles, aspects, and lithology, providing estimates of rock fall rates over geologic timescales. Repeat scanning of three recent large (850 to 45,200 m (super 3) ) rock falls provide accurate and precise rock-fall volumes at far range (volumetric precision of approximately 1% even at scan distances >1.2 km). At close range, terrestrial laser scanning can potentially resolve small ( approximately 1 cm) deformation of rock flakes, which we demonstrate occurs on the cliffs of Yosemite Valley. Airborne and terrestrial laser scanning also provide data for assessing hazards associated with potential future rock falls. Structural data, obtained by plane-fitting of discontinuity-controlled bedrock surfaces and verified by field measurements, clarify potential rock fall modes. Raw point cloud data prove more valuable for structural analyses than gridded DEMs, as point cloud data better resolve overhanging surfaces and fine-scale features such as sheeting joints that are essential components of stability assessment. Automated structural analyses, computed with Coltop3D software, and simple kinematic tests indicate relative rock-fall susceptibility for Yosemite Valley's cliffs by mapping the dominant discontinuity sets and identifying cliff areas potentially subject to planar or wedge failures. Numerical model (STONE) simulations, calibrated to recent rock falls, delineate runout areas for rock falls originating from areas identified as having high rock-fall susceptibility. Each of these LiDAR-based analyses provides critical information for park managers charged with balancing public use with public safety in one of the world's most frequently visited National Parks.

Dives were focused on 15 locations selected by 3-D seismic surface attributes and shallow subsurface geologic analyses. The linkage between highly positive seafloor reflectivity and hard bottoms proved to be an efficient indicator of potential sites of interest. Through observation and sampling of reflective sites, starting in the mid-1980s, it has become apparent that most hard bottoms on the northern Gulf's continental slope are created by the precipitation of authigenic carbonates at hydrocarbon seep sites. Access to the Bureau of Ocean Energy Management, Regulation and Enforcement's extraordinary archive of slope-wide 3-D seismic data made efficient site selection possible. From thousands of sites that display the characteristics of fluid-gas expulsion, 15 were observed and sampled during the 2006 and 2007 cruises. Water depths in which these 15 sites were located ranged from approximately 2750 to approximately 970 m. All sites exhibited evidence of hydrocarbon seepage or more rapid venting. Chemosynthetic organisms, authigenic carbonates, barite, gas hydrates, highly anoxic surface sediments, brine pools, and hydrocarbon-laced brine flows were identified and sampled. High-resolution acoustic Autonomous Underwater Vehicle (AUV) data, including multibeam bathymetry, side-scan sonar swaths, and chirp sonar subbottom profiles, were collected at four locations (AC601, WR269, GC852, and AT340). Data sets from the 2006 and 2007 dives resulted in a greatly improved understanding of both cross-slope and along-slope variability in the characteristics of fluid-gas expulsion sites and associated habitats.

The most notable, pervasive, predominant, and aerial extensive geomorphic features mapped were upland glaciated mesas and buttes. These nearly flat-topped to gently-rolling glacially eroded bedrock landmasses, rise distinctly and abruptly above the deeply scoured alpine glacial valleys. Statistically measureable parameters used to define, measure, and analyze these features were: bedrock type, orientation, slope direction, slope, and active Holocene glaciers. Preliminary observations indicate that the upland butte density is highest in an area of a former large ice center and distal to the mesas, where as upland mesa density is highest away from these former ice centers and along the sides. The largest mesas are on the eastern slopes of the WRM, indicating the possibility of a very large ice mass that originating in the Green River valley (GRV), topping the WRM, and spreading outward into the Wind River valley. Glacial geomorphic mapping of: cirques, compound cirques, deeply carved bedrock u-shaped valleys, overridden horns, horns, as well as active Holocene glaciers, indicated a definitive spatial relationship to the upland mesa and buttes. Statistical analysis of these mapped features will aid in determining the possible origin and extent of ice coverage, paleo-ice flow patterns, and the glacial history of the WRM, as well as their relationship to the surrounding Green River and Wind River valleys. Current distribution of these features as well as the active Holocene glaciers suggests that at one time ice nearly covered the entire core of the WRM, and the majority of the GVR, except for the highest peak, Gannett.

The fossils occur in sediments representing distal alluvial fan channel, distal fan overbank flood or sheetflood, and marsh/lacustrine deposits of the upper unit of the Turlock Lake Formation. Among the fauna are three ground sloth species; Megalonyx wheatleyi, Nothrotheriops shastensis and Paramylodon harlani. In the summer of 1993, remains of all three sloth species were recovered from a relatively narrow stratigraphic zone (12.2 m to 12.8 m below the surface) and from close horizontal proximity to each other (within 90 m). During the year 2006 excavation, dozens of Paramylodon specimens representing at least 6 individuals were collected from an alluvial fan channel deposit 14.6 m to 15.8 m below ground surface in a 15 m X 40 m area. Between excavation years 1993 and 2008, paleontological monitors recovered another 30 sloth specimens from Fairmead Landfill, all Paramylodon except a Nothrotheriops cranium. Of those 30 specimens, 16 associated elements recovered in 2003 appear to represent one individual. Co-occurrence of these three sloth taxa in a single fauna is rare in both the Irvingtonian and Rancholabrean, a reflection of the different ecological requirements of each species. This is only the fourth documented Irvingtonian fauna to contain all three sloth genera. Typically, in areas of co-occurrence one taxon is more common than others. At Fairmead Landfill, Paramylodon, a grazer/mixed feeder, dominates the sloth assemblage with multiple individuals ranging from neonates to adults. The browsers Megalonyx and Nothrotheriops are represented by a minimum of one adult and two adults and a juvenile, respectively. The high frequency of the grazing species is consistent with composition of the assemblage as a whole, which is dominated by presumed open-country grazers Equus sp., Camelops sp., and Mammuthus columbi. Evolutionarily the Fairmead Landfill sloths exhibit morphological, size and proportional characters that suggest they represent transitional populations between older and younger members of their respective lineages.

Using leaf margin analysis, a mean annual temperature of 20 degrees C (+ or - 2 degrees C) was estimated from 45 morphotypes from the Moonlight flora. Also present at Moonlight are fossil fruits, ferns, and a palm. Conifers have been collected at Susanville but not Moonlight. The age of the Moonlight and Susanville floras has long been regarded as Eocene, an interpretation supported by the presence of the genus Macginitiea. U/Pb dating of detrital zircons at both localities was undertaken using laser-ablation ICP-MS at UCSB to refine this age estimate. A tuff layer stratigraphically below the main fossil-bearing layer at Moonlight is dominated by 34.8Ma (+ or - 0.7my) zircons. A detrital sample from the fossil bearing sandstone at Moonlight contains Eocene, Cretaceous, Paleozoic and Proterozoic zircons. Based on the youngest peak age in the detrital sandstone sample, the maximum depositional age of the fossil deposit at Moonlight is approximately 35Ma. This is much closer to the Eocene/Oligocene boundary than was previously thought based on comparison with the Chalk Bluffs and Clarno floras. At Susanville, a reworked tuff stratigraphically above the flora has its largest and youngest detrital zircon age peak ca. 35Ma, with the second largest age peak ca. 100Ma matching the age of the underlying granite. Thus the Susanville flora could be 35Ma or older. These first attempts at radiometric dates for Moonlight at Susanville provide a context for future work on Cenozoic terrestrial environmental change in the northern Sierra Nevada. A geochemical analysis of the tuff at Moonlight will provide data for comparison with other approximately 35Ma tuffs in the western North America and may aid in locating a source area for the volcanic material. The detrital zircon data from Moonlight and Susanville, along with detrital zircon analyses from other channels, may hold clues to the drainage patterns of the "auriferous gravels" paleochannels.

STSPs can also provide personal connections among students, teachers, and scientists. Many challenges exist, however, in the implementation of these partnerships. Here we describe a partnership, Students Teachers and Rangers & Research Scientist (STaRRS): Investigating Systems at Mammoth Hot Springs, which was embedded within an existing National Park Service (NPS) residential educational program for 4 (super th) -8 (super th) grade students called Expedition: Yellowstone! (E:Y!). Since this STSP directly integrated with E:Y!, several of the known challenges were addressed. The STaRRS partnership within E:Y! will be presented as a model for the future development of education connecting Geoscience research to teachers and student in the NPS. Three basic components to this project that improved the partnership included: (a) extensive teacher professional development provided as summer workshops and on-going school year assistance with access to science and science education expertise; (b) carefully developed science investigations which clearly engaged the students; and (c) the use of a science education liaison to aid with implementation and communication among the partners. An accompanying research study found significant results in attitude changes regarding science and scientists and geoscience content knowledge gains in participating teachers and middle level students.

The project uses Earth Systems Science (ESS) content and inquiry-based instructional practices to emphasize themes that unite sciences and mathematics. The MiTEP project tenders a partnership of academia, K-12 educators and the National Park Service (NPS) for improving Earth Science education. All stakeholders provide expertise and can benefit from one another in an effort to truly achieve learner-centered Earth Science education. Academia provides the foundation upon which greater depth and enrichment of Earth Science content can be realized; K-12 educators directly integrate and apply this content in the classroom. Important to place-based Earth Science education, national parks are obvious focal points as they contain spectacular examples of the processes that shape the Earth and influence ecosystem development. National parks afford excellent examples of places that hold intellectual and emotional stimulus. Incorporating different methods of learning about Earth's processes engages a wider audience of students. The NPS provides a plethora of opportunities to achieve this end. The Views of the National Parks (Views) program is a multimedia education program that provides natural, historical, and cultural learning resources associated with national parks. In addition to this, teachers may participate in Geoscientists-in-the-Parks, Volunteers-in-Parks or the Teacher-Ranger-Teacher programs. Through these various programs and resources MiTEP teachers will work with national park interpreters to learn more about engaging diverse learners in scientific inquiry based on the natural environment. Examples using national parks in the Colorado Plateau and Rocky Mountains as outdoor classrooms for teachers will be presented. It is paramount that all stakeholders work in tandem to develop place-based education strategies that enhance Earth Science curriculum. This network aims to develop a stronger appreciation of environment and geological processes and connections between what K-12 students do and their impact on Earth systems.

Yet many National Park interpreters struggle to present the geologic history of their parks to the public in a meaningful and relevant way. Interpretive theory states that programs should provide both intellection and emotional opportunities for visitors to connect with natural resources. As a scientific discipline, geology lends itself naturally to intellectual connections, but the emotional domain presents greater challenges. Workers pursuing sense of place research have demonstrated that academic courses designed with the affective dimensions of learning in mind can produce both greater content understanding and stewardship attitudes in participants. With the aim to enrich the experiences of National Park visitors and guide NPS interpreters, a mixed methods study was designed to generate grounded theory on the subject of geologic resource interpretation, with particular focus on its emotional dimensions. At 12 different National Parks and Monuments, two to five geology-themed interpretive programs were filmed and analyzed for intellectual and emotional connection opportunities, while visitors were administered pre- and post-questionnaires, or interviewed as members of focus groups. The resultant qualitative and quantitative data provide insight into the geoscience experience of visitors on public lands, and offer a palette of best practices for interpreters.

While geoscience is an important component of curriculum-based education, it is also a critical tool for fostering park stewardship. However, geoscience education and interpretation in national parks can be a daunting task for park rangers. Students may be more interested in other subjects, and park staff often does not have a strong geologic background or training in geologic interpretation techniques. Through the Geological Society of America's GeoCorps America (super TM) Program, in partnership with the Geoscientists-in-Parks Program, a geoscientist was temporarily placed in the Environmental Education Division at Rocky Mountain National Park. Throughout the 2009 spring season, the participant prepared and presented geoscience education programs for school groups ranging from kindergarten to the college-level. As a result of this experience, several insights were made regarding strategies for engaging students in geoscience learning activities while inspiring them to protect and explore the national park. The three factors recognized to have the greatest control on student engagement were (1) instructor knowledge and enthusiasm, (2) activity type, and (3) social setting. These factors will be explored and related to the participant's experience at Rocky Mountain National Park.

Interpretive programs run the gamut between cultural history stories and classic science-based lessons. Prior to working with the public, summer seasonal interpretive rangers at Glacier National Park receive intense, eighty-hour training on the myriad natural and cultural features, and potential social issues of that spectacular park. This occurs over two weeks and includes all of three hours devoted to geologic instruction. Given the variety of educational and life experience backgrounds of the audience, instructors must assume no prior geologic knowledge or education, meaning much of the session includes very basic geologic concepts in an extremely limited timeframe. We have produced a curriculum that spends 50 minutes on basic geologic concepts (aka Bachelors Degree) discussing geologic time, the three types of rocks and the rock cycle, plate tectonics with an emphasis on compression, and glaciers and glacial features. This is followed by 50 minutes on the geologic evolution of Glacier National Park including Precambrian Belt Basin stratigraphy, thrusting on the Lewis overthrust fault, extension in the Kishenehn basin along the western edge of the park, Pleistocene glaciation, and resulting glacial features throughout the park after glacial retreat (aka Masters Degree). We conclude with 50 minutes on specific geologic features a visitor might observe in the park such as the Lewis overthrust, stromatolites within the Helena limestone formation, pillow basalts, U-shaped valleys, rock colors, and the Purcell diorite sill (aka Phd). Instructors attempt to engage the class using plenty of photographs, cookies, silly putty, M&Ms, and as much humor as possible.

In the western United States, where the combined climatic demand and consumptive use of water is equal to or greater than the natural supply of water for some locations, there is growing concern regarding the sustainability of future water supplies. In addition to the adverse effects of warming on water supply, another issue for water managers is accounting for, and managing, the effects of natural climatic variability, particularly persistently dry and wet periods. Analyses of paleo-reconstructions of Upper Colorado River basin (UCRB) flow demonstrate that severe sustained droughts, and persistent pluvial periods, are a recurring characteristic of hydroclimate in the Colorado River basin. Shifts between persistently dry and wet regimes (e.g., decadal to multi-decadal variability (D2M)) have important implications for water supply and water management. In this study paleo-reconstructions of UCRB flow are used to compute the risks of shifts between persistently wet and dry regimes given the length of time in a specific regime. Results indicate that low frequency variability of hydro-climatic conditions and the statistics that describe this low frequency variability can be useful to water managers by providing information about the risk of shifting from one hydrologic regime to another. To manage water resources in the future water managers will have to understand the joint hydrologic effects of natural climate variability and global warming. These joint effects may produce future hydrologic conditions that are unprecedented in both the instrumental and paleoclimatic records.

Limited aerial surveys indicate that this area supports tens of thousands of king eiders and black scoters during spring migration and the autumn molt. Existing satellite telemetry data were used to assess the temporal patterns of habitat use and spatial distribution of king eiders and black scoters in northeastern Bristol Bay throughout the annual cycle. King eiders used northeastern Bristol Bay during all months of the annual cycle and black scoters used the area during spring through fall. Both species exhibited a similar seasonal pattern of use that corresponded with the timing of life-cycle stages. Abundance of both species was highest during spring migration and the autumn molting period and lowest during summer. Use by king eiders did not occur during all winter months in every year of the study. King eiders were more broadly distributed than black scoters and were located farther from shore in deeper water. Core use areas had minimal overlap, suggesting a degree of spatial segregation between species and a preference for different habitats in northeastern Bristol Bay. Further study of potential variation in invertebrate community structure that may correlate with the observed interspecific spatial segregation in habitat use is needed to determine preferred forage and describe habitat requirements for each species. Such information is necessary to assess the potential impact that future anthropogenic or environmental changes may have on habitat quality of northeastern Bristol Bay and demography of Pacific sea duck populations that use this area.

We developed an individual-based model to evaluate how brucellosis infection might respond under alternate vaccination strategies, including: (1) vaccination of female calves and yearlings captured at the park boundary when bison move outside the primary conservation area; (2) combining boundary vaccination with the remote delivery of vaccine to female calves and yearlings distributed throughout the park; and (3) vaccinating all female bison (including adults) during boundary capture and throughout the park using remote delivery of vaccine. Simulations suggested Alternative 3 would be most effective, with brucellosis seroprevalence decreasing by 66% (from 0.47 to 0.16) over a 30-year period resulting from 29% of the population receiving protection through vaccination. Under this alternative, bison would receive multiple vaccinations that extend the duration of vaccine protection and defend against recurring infection in latently infected animals. The initial decrease in population seroprevalence will likely be slow due to high initial seroprevalence (40-60%), long-lived antibodies, and the culling of some vaccinated bison that were subsequently exposed to field strain Brucella and reacted positively on serologic tests. Vaccination is unlikely to eradicate B. abortus from Yellowstone bison, but could be an effective tool for reducing the level of infection. Our approach and findings have applicability world-wide for managers dealing with intractable wildlife diseases that cross wildlife-livestock and wildlife-human interfaces and affect public health or economic well-being.

An unusual drainage response was identified, which was characterized by sharp drainage from saturation to near field capacity at each depth with an increased delay between depths. We simulated the drainage response using a variably saturated numerical flow model representing a two-layer system with a high permeability layer overlying a lower permeability layer. Both the observed data and the numerical simulation show a strong correlation between the drainage velocity and the temperature of the stream water. A linear combination of temperature and the no-flow period preceding flow explained about 90% of the measured variations in drainage velocity. Evaluation of this correlative relationship with the one-dimensional numerical flow model showed that the observed temperature fluctuations could not reproduce the magnitude of variation in the observed drainage velocity. Instead, the model results indicated that flow duration exerts the most control on drainage velocity, with the drainage velocity decreasing nonlinearly with increasing flow duration. These findings suggest flow duration is a primary control of water availability for plant uptake in near surface sediments of an ephemeral stream, an important finding for estimating the ecological risk of natural or engineered changes to streamflow patterns. Correlative analyses of soil moisture data, although easy and widely used, can result in erroneous conclusions of hydrologic cause--effect relationships, and demonstrating the need for joint physically-based numerical modeling and data synthesis for hypothesis testing to support quantitative risk analysis.

Other than the pronounced transients at Mount St. Helens and Mount Baker, hydrothermal heat discharge in the Cascade Range appears to be fairly steady over a ~ 25-year period of measurement. Of the total of ~ 1050 MW of "steady" hydrothermal heat discharge identified in the U.S. part of the Cascade Range, less than 50 MW occurs north of latitude 45 degree N (~ 0.1 MW per km arc length from 45 degree to 49 degree N). Much greater rates of hydrothermal heat discharge south of 45 degree N (~ 1.7 MW per km arc length from 40 to 45 degree N) may reflect the influence of Basin and Range-style extensional tectonics (faulting) that impinges on the Cascades as far north as Mount Jefferson but is not evident farther north.

Juvenile steelhead populations were sampled from mid-June through August 2004 at study sites upstream and downstream of Hemlock Dam. The growth and diet of juvenile steelhead were determined for a warm (summer) and subsequent (late summer) transitional period at each study site. Empirical data on the growth and diet of juvenile steelhead and mean daily temperatures were used in a bioenergetics model to estimate the proportion of maximum consumption achieved by juvenile steelhead by site and period. Modeled estimates of feeding performance were better for juvenile steelhead at the upstream compared to the downstream site during both periods. The median condition factor of juvenile steelhead did not change over the summer at the upstream site, but showed a significant decline over time at the downstream site. A negative trend in median condition factor at the downstream site supported bioenergetics modeling results that suggested the warmer stream temperatures had a negative impact on juvenile steelhead. Bioenergetics modeling predicted a lower feeding performance for juvenile steelhead rearing downstream compared to upstream of Hemlock Dam although food availability appeared to be limited at both study sites during the warm period. Warmer water temperatures, greater diel variation, and change in diel pattern likely led to the reduced feeding performance and reduced growth, which could have affected the overall survival of juvenile steelhead downstream of Hemlock Dam.

Their protection and restoration have been one of the top environmental management priorities across the US over the last several years. Despite the level of concern, visibility and management effort, little is known about trends in riparian habitats. Moreover, little is known about whether or not cumulative efforts to restore and protect riparian zones and floodplains are affecting the rates of riparian habitat change nationwide. To address these issues, we analyzed riparian land cover change between the early 1970s and the late 1990s/early 2000s using existing spatial data on hydrography and land cover. This included an analysis of land cover changes within 180m riparian buffer zones, and at catchment scales, for 42,363 catchments across 63 ecoregions of the continental US. The total amount of forest and natural land cover (forests, shrublands, wetlands) in riparian buffers declined by 0.7 and 0.9%, respectively across the entire study period. Gains in grassland/shrubland accounted for the 0.2% lower percentage of total natural land cover loss relative to forests. Conversely, urban and developed land cover (urban, agriculture, and mechanically disturbed lands) increased by more than 1.3% within riparian buffers across the entire study period. Despite these changes, we documented an opposite trend of increasing proportions of natural and forest land cover in riparian buffers versus the catchment scale. We surmise that this trend might reflect a combination of natural recovery and cumulative efforts to protect riparian ecosystems across the US. However, existing models limit our ability to assess the impacts of these changes on specific ecosystem services. We discuss the implications of changes observed in this study on the sustainability of ecosystem services. We also recommend opportunties for future riparian change assessments.

Large flood events are now rare in the lower basins of most large river systems due to flood control structures. Endemic organisms that are adapted to this historical disturbance regime have become less abundant due to these dramatic changes in the hydrology and the resultant changes in vegetation structure. The Yuma Clapper Rail is a federally endangered bird that breeds in emergent marshes within the lower Colorado River basin in the southwestern United States and northwestern Mexico. We evaluated whether prescribed fire could be used as a surrogate disturbance event to help restore historical conditions for the benefit of Yuma Clapper Rails and four sympatric marsh-dependent birds. We conducted call-broadcast surveys for marsh birds within burned and unburned (control) plots both pre- and post-burn. Fire increased the numbers of Yuma Clapper Rails and Virginia Rails, and did not affect the numbers of Black Rails, Soras, and Least Bitterns. We found no evidence that detection probability of any of the five species differed between burn and control plots. Our results suggest that prescribed fire can be used to set back succession of emergent marshlands and help mimic the natural disturbance regime in the lower Colorado River basin. Hence, prescribed fire can be used to help increase Yuma Clapper Rail populations without adversely affecting sympatric species. Implementing a coordinated long-term fire management plan within marshes of the lower Colorado River may allow regulatory agencies to remove the Yuma Clapper Rail from the endangered species list.

Arrays of portable seismic stations are used to target four study areas with different ground motion patterns: (1) an edge of the alluvial basin extending up onto a marginal ridge (Blossom Hill), (2) a Cenozoic basin with a nearly flat bottom (Cupertino Basin), (3) a long, narrow Cenozoic basin with a steep V profile (Evergreen Basin), and (4) a line perpendicular to the trace of the Hayward fault. Average peak velocities on Blossom Hill from local earthquakes are a factor of 2.5 times higher than nearby valley sites. Three-dimensional (3D) modeling is used to conclude that the majority of the amplification is due to lower shear-wave velocities along a local fault zone (Shannon-Berrocal). Site amplification over the Cupertino Basin in the frequency band 0.5-4 Hz is generally low (less than 2.0 relative to a Mesozoic rock site) and spatially uniform. This response is attributed to the shallow, flat-bottomed shape of the basin and the uniform, flat-laying sedimentary fill. In contrast, site amplification in the Evergreen Basin generally exceeds 3.0 and is attributed to the deep, V-shaped geometry of the basin and younger sedimentary fill. 3D waveform modeling shows the elongated shape of the Evergreen Basin causes more efficient trapping of long-period waves for sources along the long axis of the basin. A low-velocity zone is postulated along the Hayward fault with a width between 100 and 200 m, based on elevated site response along the fault trace and 4.5-Hz fault zone guided waves on the horizontal components of stations near the fault.

In the absence of historical records of sediment pollution, ratios of coral Ba/Ca were used to test the hypothesis that sedimentation has increased over time. Baseline Ba/Ca ratios co-vary with the abundance of red, terrigenous sediment visible in recent imagery. The highest values at One Ali'i are near one of the muddiest parts of the reef. This co-varies with the lowest growth rate of all the sites, perhaps because the upstream Kawela watershed was historically leveed all the way to the nearshore, providing a fast-path for sediment delivery. Sites adjacent to small, steep watersheds have decadal periodicities whereas sites adjacent to mangrove forests have shorter-period fluctuations that correspond to the periodicity of sediment transport in the nearshore, rather than the watershed. All four sites show a statistically significant upward trend in Ba/Ca.

In 2006-2007, studies to assess levels of total mercury (THg) found concentrations in unfiltered streamwater to range as high as 187ng/L in urbanized areas. THg concentrations were <20ng/L in streamwater in forested/wetlands areas where both THg and dissolved organic carbon concentrations tended to increase while pH and concentrations of dissolved oxygen and nitrate decreased with flushing of soils after rain. Most of the river's flow comes from groundwater seepage; unfiltered groundwater samples contained up to 177ng/L of THg in urban areas where there is a history of well water with THg that exceeds the drinking water standard (2,000ng/L). THg concentrations were lower (<25ng/L) in unfiltered groundwater from downstream wetland areas. In addition to higher THg concentrations (mostly particulate), concentrations of chloride were higher in streamwater and groundwater from urban areas than in those from downstream wetland areas. Methylmercury (MeHg) concentrations in unfiltered streamwater ranged from 0.17ng/L at a forest/wetlands site to 2.94ng/L at an urban site. The percentage of THg present as MeHg increased as the percentage of forest + wetlands increased, but also was high in some urban areas. MeHg was detected only in groundwater <1m below the water/sediment interface. Atmospheric deposition is presumed to be the main source of Hg to the wetlands and also may be a source to groundwater, where wastewater inputs in urban areas are hypothesized to mobilize Hg deposited to soils.

These habitats are generally considered to be fire intolerant and the effects from fire are a major concern for land managers. This study investigated trends of ecosystem response to fire by looking at a chronosequence of historic burns. Plots were chosen at 2, 9, 13, 15 19, and 65aayears since burn in which to sample vegetation and rodent communities. Rodent diversity was lower in burned plots and increased over time. The abundance of rodents however, was not significantly different between the burned and unburned plots. Vegetation showed a directional change in species composition with time since fire. However, reestablished vegetation assemblages did not converge to the assumed pre-burn condition. It is probable that this difference relates to the slow rates of establishment of certain vegetation components that make up the pre-burn condition of the plots. There is a concern that invasion by exotic plant species, nitrogen deposition, and global climate change may initiate a fire cycle in this ecosystem that will arrest succession before the Joshua tree woodland is allowed to reestablish.

AN - 755968605; 20806974 AB - A new perspective on the severity of aquatic toxicity impact of road salt was gained by a focused research effort directed at winter runoff periods. Dramatic impacts were observed on local, regional, and national scales. Locally, samples from 7 of 13 Milwaukee, Wisconsin area streams exhibited toxicity in Ceriodaphnia dubia and Pimephales promelas bioassays during road-salt runoff. Another Milwaukee stream was sampled from 1996 to 2008 with 72% of 37 samples exhibiting toxicity in chronic bioassays and 43% in acute bioassays. The maximum chloride concentration was 7730 mg/L. Regionally, in southeast Wisconsin, continuous specific conductance was monitored as a chloride surrogate in 11 watersheds with urban land use from 6.0 to 100%. Elevated specific conductance was observed between November and April at all sites, with continuing effects between May and October at sites with the highest specific conductance. Specific conductance was measured as high as 30,800 μS/cm (Cl = 11,200 mg/L). Chloride concentrations exceeded U.S. Environmental Protection Agency (USEPA) acute (860 mg/L) and chronic (230 mg/L) water-quality criteria at 55 and 100% of monitored sites, respectively. Nationally, U.S. Geological Survey historical data were examined for 13 northern and 4 southern metropolitan areas. Chloride concentrations exceeded USEPA water-quality criteria at 55% (chronic) and 25% (acute) of the 168 monitoring locations in northern metropolitan areas from November to April. Only 16% (chronic) and 1% (acute) of sites exceeded criteria from May to October. At southern sites, very few samples exceeded chronic water-quality criteria, and no samples exceeded acute criteria.

AN - 755401119; 20872649 AB - The main route of exposure for selenium (Se) is dietary, yet regulations lack biologically based protocols for evaluations of risk. We propose here an ecosystem-scale model that conceptualizes and quantifies the variables that determine how Se is processed from water through diet to predators. This approach uses biogeochemical and physiological factors from laboratory and field studies and considers loading, speciation, transformation to particulate material, bioavailability, bioaccumulation in invertebrates, and trophic transfer to predators. Validation of the model is through data sets from 29 historic and recent field case studies of Se-exposed sites. The model links Se concentrations across media (water, particulate, tissue of different food web species). It can be used to forecast toxicity under different management or regulatory proposals or as a methodology for translating a fish-tissue (or other predator tissue) Se concentration guideline to a dissolved Se concentration. The model illustrates some critical aspects of implementing a tissue criterion: 1) the choice of fish species determines the food web through which Se should be modeled, 2) the choice of food web is critical because the particulate material to prey kinetics of bioaccumulation differs widely among invertebrates, 3) the characterization of the type and phase of particulate material is important to quantifying Se exposure to prey through the base of the food web, and 4) the metric describing partitioning between particulate material and dissolved Se concentrations allows determination of a site-specific dissolved Se concentration that would be responsible for that fish body burden in the specific environment. The linked approach illustrates that environmentally safe dissolved Se concentrations will differ among ecosystems depending on the ecological pathways and biogeochemical conditions in that system. Uncertainties and model sensitivities can be directly illustrated by varying exposure scenarios based on site-specific knowledge. The model can also be used to facilitate site-specific regulation and to present generic comparisons to illustrate limitations imposed by ecosystem setting and inhabitants. Used optimally, the model provides a tool for framing a site-specific ecological problem or occurrence of Se exposure, quantify exposure within that ecosystem, and narrow uncertainties about how to protect it by understanding the specifics of the underlying system ecology, biogeochemistry, and hydrology. © 2010 SETAC.

AN - 755400051; 20872693 AB - Belted kingfisher (Ceryle alcyon), spotted sandpiper (Actitus macularia), and tree swallow (Tachycineta bicolor) eggs were collected in 2004 from the upper Hudson River, New York, USA. This area is one of the most polychlorinated biphenyl (PCB)-contaminated locations in North America. Multivariate analyses indicated among species differences in the concentration and composition of PCB congeners, polychlorinated dibenzo-p-dioxin (PCDD), and dibenzofuran (PCDF, PCDD-F when combined with PCDDs) congeners, and chlorinated pesticides. Total PCB concentrations followed the typical food chain biomagnification paradigm of higher concentrations in piscivorous bird eggs and lower concentrations in eggs of species that feed at lower trophic levels. Concentrations in the insectivorous swallows (geometric mean = 6.8 µg/g wet wt) were approximately half the concentrations present in the piscivorous kingfisher (11.7 µg/g) or omnivorous sandpiper (12.6 µg/g). In contrast, PCB toxic equivalents (TEQs) were higher in swallows (1,790 pg/g wet wt) than in either kingfishers (776 pg/g) or sandpipers (881 pg/g). This difference can be mainly attributed to higher PCB77 concentrations in swallows relative to the other two species. Also contrary to the accepted food-chain paradigm, the sum of PCDD-F concentrations and the sum of their TEQs were higher in swallows than in either sandpipers or kingfishers. Metabolic pathway differences in the respective food chains of the three species probably accounted for the differences observed in PCB TEQ, total PCDD-F, and PCDD-F TEQ concentrations among species.

Dietary treatment was terminated after 12 to 14 weeks, and unhatched eggs were collected for Hg analysis. Blood samples were collected after four weeks of treatment and the termination of the study (i.e., 12-14 weeks of treatment). Clutch size decreased at dietary concentrations above 2.8 [mu]g/g. The average total mercury concentration in clutches of eggs and in the second egg laid (i.e., egg B) increased linearly with dietary concentration. Mercury concentrations in egg B were approximately 25% lower than in the first egg laid and similar in concentration to the third egg laid. Mercury concentrations in whole blood and plasma also increased linearly with dietary concentration. Total Hg concentrations in June blood samples were lower than those in April, despite 8 to 10 weeks of additional dietary exposure to MeHg in the diet. This is likely because of excretion of Hg into growing flight feathers beginning shortly after the start of egg production. The strongest relationships between Hg concentrations in blood and eggs occurred when we used blood samples collected in April before egg laying and feather molt.

As biocrusts fix nitrogen (N), they are an important part of restoring soil fertility. We measured nitrogenase activity (NA) in biocrusts from sites rehabilitated at six different time periods to estimate 1) the effects of moisture content and temperature on NA in biocrusts of different ages and 2) the potential N contribution from biocrusts to soils and plants in this region. Results show that NA in the biocrusts was mostly controlled by the species composition, as the activity of biocrusts dominated by free-living soil cyanobacteria was significantly higher than that of moss-dominated biocrusts. Nitrogenase activity was also influenced by soil moisture content and ambient temperature, with a significant decline in activity when moisture levels were decreased to 20% field water-holding capacity. The optimal temperature for NA was 35-40 degree C and 30-40 degree C for cyanobacteria- and moss-dominated biocrusts, respectively.

The model formulation consists of governing equations for integrated surface water and groundwater flow, sediment transport, and soil accretion, as well as litter production by vegetation growth. The model simulations show how the spatial pattern self-organizes over time with the generation of ridges and sloughs through sediment deposition and erosion driven by the water flow field. The spatial and temporal distributions of the water depth, flow rates and sediment transport processes are caused by differential flow due to vegetation and topography heterogeneities. The model was parameterized with values that are representative of the Everglades wetland in the southern portion of the Florida peninsula in the USA. Model simulation sensitivity was tested with respect to numerical grid size, lateral vegetation growth and the rate of litter production. The characteristic wavelengths of the pattern in the directions along and perpendicular to flow that are simulated with this model develop over time into ridge and slough shapes that resemble field observations. Also, the simulated elevation differences between the ridges and sloughs are of the same order of those typically found in the field. The width of ridges and sloughs was found to be controlled by a lateral vegetation growth distance parameter in a simplified formulation of vegetation growth, which complements earlier modeling results in which a differential peat accretion mechanism alone did not reproduce observations of ridge and slough lateral wavelengths. The results of this work suggest that ridge and slough patterning occurs as a result of vegetation's ability to grow laterally, enhancing sediment deposition in ridge areas, balanced by increased sediment erosion in slough areas to satisfy flow continuity. The interplay between sediment transport, water flow and vegetation and soil dynamic processes needs to be explored further through detailed field experiments, using a model formulation such as the one developed in this work to guide data collection and interpretation. This should be one of the focus areas of future investigations of pattern formation and stability in ridge and slough areas. Abstract Copyright (2010) Elsevier, B.V.

Trace element chemistry AN - 1093435576; 13942841 AB - The Gibbon River in Yellowstone National Park receives inflows from several geothermal areas, and consequently the concentrations of many trace elements are elevated compared to rivers in non-geothermal watersheds. Water samples and discharge measurements were obtained from the Gibbon River and its major tributaries near Norris Geyser Basin under the low-flow conditions of September 2006 allowing for the identification of solute sources and their downstream fate. Norris Geyser Basin, and in particular Tantalus Creek, is the largest source of many trace elements (Al, As, B, Ba, Br, Cs, Hg, Li, Sb, Tl, W, and REEs) to the Gibbon River. The Chocolate Pots area is a major source of Fe and Mn, and the lower Gibbon River near Terrace Spring is the major source of Be and Mo. Some of the elevated trace elements are aquatic health concerns (As, Sb, and Hg) and knowing their fate is important. Most solutes in the Gibbon River, including As and Sb, behave conservatively or are minimally attenuated over 29 km of fluvial transport. Some small attenuation of Al, Fe, Hg, and REEs occurs but primarily there is a transformation from the dissolved state to suspended particles, with most of these elements still being transported to the Madison River. Dissolved Hg and REEs loads decrease where the particulate Fe increases, suggesting sorption onto suspended particulate material. Attenuation from the water column is substantial for Mn, with little formation of Mn as suspended particulates.

Lianas and other climbers are important ecological and structural components of forest communities. Like other plants, their abundance in a given habitat depends on a variety of factors, such as light, soil moisture and nutrients. However, since lianas require external support, host tree characteristics also influence their distribution. Lianas are conspicuous life forms in tropical regions, but in temperate areas, where they are less prominent, little is known about factors that control their distributions in these forests. We surveyed the climbing plant species in 20 mature (100 years and greater) forested habitats in the Midwest USA at a variety of levels from simple presence/absence, to ground layer abundances, to those species that had ascended trees. We also examined attributes of the tree species with climbers attached to them. Using cluster analysis, we distinguished five different tree communities in our survey locations. We determined that 25% of the trees we surveyed had one or more lianas attached to it, with Parthenocissus quinquefolia (Virginia creeper) the most common climbing species encountered. Canopy cover and soil attributes both influenced climber species presence/absence and ground layer climber abundance. The proportion of liana species of a given climbing type (roots, stem twiner, tendril climber) was significantly related to the DBH of the host tree, with more root climbers and fewer stem and tendril climbers on large trees. In general, the DBH of climbing lianas had a significant positive relationship to the DBH of the host tree; however this varied by the identity of the liana and the tree species. The greater the DBH of the host tree, the higher the probability that it was colonized by one or more lianas, with tree species such as Pinus banksiana (jack pine) and Quercus alba (white oak) being more susceptible to liana colonization than others. Finally, some liana species such as Celastrus scandens (American bittersweet) showed a preference for certain tree species (i.e., P. banksiana) as hosts. The information obtained about the relationship between the tree and climber community in this study provides insight into some of the factors that influence liana distributions in understudied temperate forest habitats and how lianas contribute to the structure of these mature forests. In addition, these data can provide a point of comparison to other liana communities in both temperate and tropical regions.

The western landmass, known as Laramidia, although diminutive in size, witnessed a major evolutionary radiation of dinosaurs. Other than hadrosaurs (duck-billed dinosaurs), the most common dinosaurs were ceratopsids (large-bodied horned dinosaurs), currently known only from Laramidia and Asia. Remarkably, previous studies have postulated the occurrence of latitudinally arrayed dinosaur "provinces", or "biomes", on Laramidia. Yet this hypothesis has been challenged on multiple fronts and has remained poorly tested. Here we describe two new, co-occurring ceratopsids from the Upper Cretaceous Kaiparowits Formation of Utah that provide the strongest support to date for the dinosaur provincialism hypothesis. Both pertain to the clade of ceratopsids known as Chasmosaurinae, dramatically increasing representation of this group from the southern portion of the Western Interior Basin of North America. Utahceratops gettyi gen. et sp. nov.--characterized by short, rounded, laterally projecting supraorbital horncores and an elongate frill with a deep median embayment--is recovered as the sister taxon to Pentaceratops sternbergii from the late Campanian of New Mexico. Kosmoceratops richardsoni gen. et sp. nov.--characterized by elongate, laterally projecting supraorbital horncores and a short, broad frill adorned with ten well developed hooks--has the most ornate skull of any known dinosaur and is closely allied to Chasmosaurus irvinensis from the late Campanian of Alberta. Considered in unison, the phylogenetic, stratigraphic, and biogeographic evidence documents distinct, co-occurring chasmosaurine taxa north and south on the diminutive landmass of Laramidia. The famous Triceratops and all other, more nested chasmosaurines are postulated as descendants of forms previously restricted to the southern portion of Laramidia. Results further suggest the presence of latitudinally arrayed evolutionary centers of endemism within chasmosaurine ceratopsids during the late Campanian, the first documented occurrence of intracontinental endemism within dinosaurs.

RefL1b is a new reflectance dataset produced for this study using ASTER Level 1B data, crosstalk correction, radiance correction factors, and concurrently acquired level 2 MODIS water vapor data. The AST_07XT data product, available from EDC and ERSDAC, incorporates crosstalk correction and non-concurrently acquired MODIS water vapor data for atmospheric correction. Spectral accuracy was determined using difference values which were compiled from ASTER band 5/6 and 9/8 ratios of AST_07XT or RefL1b data subtracted from similar ratios calculated for field sample and AVIRIS reflectance data. In addition, Spectral Analyst, a statistical program that utilizes a Spectral Feature Fitting algorithm, was used to quantitatively assess spectral accuracy of AST_07XT and RefL1b data. Spectral Analyst matched more minerals correctly and had higher scores for the RefL1b data than for AST_07XT data. The radiance correction factors used in the RefL1b data corrected a low band 5 reflectance anomaly observed in the AST_07XT and AST_07 data but also produced anomalously high band 5 reflectance in RefL1b spectra with strong band 5 absorption for minerals, such as alunite. Thus, the band 5 anomaly seen in the RefL1b data cannot be corrected using additional gain adjustments. In addition, the use of concurrent MODIS water vapor data in the atmospheric correction of the RefL1b data produced datasets that had lower band 9 reflectance anomalies than the AST_07XT data. Although assessment of spectral data suggests that RefL1b data are more consistent and spectrally more correct than AST_07XT data, the Spectral Analyst results indicate that spectral discrimination between some minerals, such as alunite and kaolinite, are still not possible unless additional spectral calibration using site specific spectral data are performed.

Nesting activity peaked in late April and May. Only the female built the nest and incubated the eggs. Males rarely visited the nest during these stages. Mean clutch size (2.1 plus or minus 0.04 eggs, n = 93) was the smallest recorded for the Slate-throated Whitestart. Incubation and nestling period lengths were 15.3 plus or minus 0.31 (n = 21) and 10.8 plus or minus 0.24 (n = 7) days, respectively. Attentiveness (% of time on the nest) during incubation (59 plus or minus 1.6%, n = 52) was similar to other tropical warblers and much lower than northern relatives. This caused a relatively low egg temperature (34.40 plus or minus 0.33 degree C, n = 6 nests, 20days) compared with north temperate birds. Both parents fed nestlings and increased their provisioning rates with nestling age. Growth rate based on nestling mass (k = 0.521 plus or minus 0.015) was faster than for other tropical passerines but slower than northern relatives. Predation was the main cause of nesting failure and rate of predation increased with age of the nest.

This study assessed which foods invertebrate consumers assimilate within a set of wetland habitats. During 2006 and 2007, non-Tanypodinae chironomid larvae and select crustaceans (Crangonyx amphipods, Caecidotea isopods, Simocephalus cladocerans) were sampled, along with their potential food sources, from forested and herbaceous areas in wetland habitats (depression, floodplain, swamp complex) across the southeastern U.S.A. Invertebrate and food source samples were processed for carbon and nitrogen isotope signatures. These data were analyzed with the U.S. Environmental Protection Agency's IsoSource mixing model, to estimate the potential relative contributions of different food items and to highlight both important and unlikely food sources. In the forested habitats, litter from trees (leaves, wood, fruit), epiphyton, detrital FPOM (fine particulate organic matter), sediment, and macrophyte litter were found to be major foods for midges and crustaceans, although considerable spatial and temporal variation existed in consumption. In the herbaceous habitats, algae (epiphyton, periphyton, metaphyton, phytoplankton), sediment, and macrophyte litter were important food resources. Comparisons between forested and herbaceous wetlands suggested that algal resources were widely consumed by midges and crustaceans, and that detrital sources were also important in forested wetlands.

Laboratory biodegradation experiments on sub-bituminous coal from Texas, USA, were conducted using bioreactors to examine the organic intermediates relevant to methane production. Production of methane in the bioreactors was linked to acetate accumulation in bioreactor fluid. Long chain fatty acids, alkanes (C sub(19)-C sub(36)) and various low molecular weight aromatics, including phenols, also accumulated in the bioreactor fluid and appear to be the primary intermediates in the biodegradation pathway from coal-derived geopolymers to acetate and methane.

The 24-h median effect concentrations (EC50s) for fatmucket glochidia (>299 mu g Pb/L, >227 mu g Cd/L, 2,685 mu g Zn/L) and 96-h EC50s for two- or six-month-old fatmucket (>426 mu g Pb/L, 199 mu g Cd/L, 1,700 mu g Zn/L) were much higher than 96-h EC50s for newly transformed fatmucket (142 and 298 mu g Pb/L, 16 mu g Cd/L, 151 and 175 mu g Zn/L) and Neosho mucket (188 mu g Pb/L, 20 mu g Cd/L, 145 mu g Zn/L). Chronic values for fatmucket were 10 mu g Pb/L, 6.0 mu g Cd/L, and 63 and 68 mu g Zn/L. When mussel data from the present study and the literature were included in updated databases for deriving U.S. Environmental Protection Agency water quality criteria, mussel genus mean acute values were in the lower percentiles of the sensitivity distribution of all freshwater species for Pb (the 26th percentile), Cd (the 15th to 29th percentile), or Zn (the 12th to 21st percentile). The mussel (Lampsilis) genus mean chronic value was the lowest value ever reported for Pb (the 9th percentile) but was near the middle of the sensitivity distribution for Cd (the 61st percentile) or Zn (the 44th percentile). These results indicate that mussels were relatively sensitive to the acute toxicity of these three metals and to the chronic toxicity of Pb, but were moderately sensitive to the chronic toxicity of Cd or Zn compared to other freshwater species.

Progress in coral disease research requires collaboration and communication among experts from many different disciplines. The lack of consistency in the use of terms and names in the recent scientific literature reflects the absence of an authority for naming coral diseases, a lack of consensus on the meaning of even some of the most basic terms as they apply to corals, and imprecision in the use of descriptive words. The lack of consensus partly reflects the complexity of this newly emerging field of research. Establishment of a nomenclature committee under the Coral Disease and Health Consortium (CDHC) could lead to more standardized definitions and could promote use of appropriate medical terminology for describing and communicating disease conditions in corals. This committee could also help to define disease terminology unique to corals where existing medical terminology is not applicable. These efforts will help scientists communicate with one another and with the general public more effectively. Scientists can immediately begin to reduce some of the confusion simply by explicitly defining the words they are using. In addition, digital photographs can be posted on the CDHC website and included in publications to document the macroscopic (gross) signs of the conditions observed on coral colonies along with precisely written characterizations and descriptions.

Since that year morbidity and mortality have also been observed in the Shenandoah and Monocacy rivers. Despite much research, no single pathogen, parasite, or chemical cause for the lesions and mortality has been identified. Numerous parasites, most commonly trematode metacercariae and myxozoans; the bacterial pathogens Aeromonas hydrophila, Aeromonas salmonicida, and Flavobacterium columnare; and largemouth bass virus have all been observed. None have been consistently isolated or observed at all sites, however, nor has any consistent microscopic pathology of the lesions been observed. A variety of histological changes associated with exposure to environmental contaminants or stressors, including intersex (testicular oocytes), high numbers of macrophage aggregates, oxidative damage, gill lesions, and epidermal papillomas, were observed. The findings indicate that selected sensitive species may be stressed by multiple factors and constantly close to the threshold between a sustainable (healthy) and nonsustainable (unhealthy) condition. Fish health is often used as an indicator of aquatic ecosystem health, and these findings raise concerns about environmental degradation within the Potomac River drainage. Unfortunately, while much information has been gained from the studies conducted to date, due to the multiple state jurisdictions involved, competing interests, and other issues, there has been no coordinated approach to identifying and mitigating the stressors. This synthesis emphasizes the need for multiyear, interdisciplinary, integrative research to identify the underlying stressors and possible management actions to enhance ecosystem health.

Eventually most states will probably allow public wolf harvesting. Open seasons between about 1 November and 1 March accord more with basic wolf biology than during other times. Managers who consider wolf biology and public sensitivities, adapt public-taking regulations accordingly, and adjust harvest regulations as they learn will be best able to maximize the recreational value of wolf harvesting, minimize public animosity toward it, and meet their harvest objectives.

We estimated N and lambda with open population models, based on live-trapping data collected from 1998 through 2006, and robust design models for genotyped hair samples collected from 2004 through 2007. Population growth was weakly negative (i.e., 95% CI included 1.0) for males (0.901, 95% CI = 0.645-1.156) and strongly negative (i.e., 95% CI excluded 1.0) for females (0.846, 95% CI = 0.711-0.981), based on live-trapping data, with N from 1999 to 2006 ranging from 94.1 (95% CI = 70.3-137.1) to 45.2 (95% CI = 27.1-109.3), respectively, for males and from 151.4 (95% CI = 127.6-185.8) to 47.1 (95% CI = 24.4-140.4), respectively, for females. Likewise, mean annual lambda based on hair-sampling data was weakly negative for males (0.742, 95% CI = 0.043-1.441) and strongly negative for females (0.782, 95% CI = 0.661-0.903), with abundance estimates from 2004 to 2007 ranging from 29.1 (95% CI = 21.2-65.8) to 11.9 (95% CI = 11.0-26.9), respectively, for males and from 54.4 (95% CI = 44.3-77.1) to 27.4 (95% CI =24.9-36.6), respectively, for females. We attribute the decline in the number of females in this isolated population to a decrease in survival caused by a past translocation program and by hunting adjacent to the refuge. We suggest that managers restructure the quota-based harvest limits until these growth rates recover.

Experimental work was carried out to study the effects of physical-chemical properties of natural minerals and chemically modified minerals on OMA formation and oil removal. The results showed that the hydrophobicity, particle sizes and specific surface of minerals played an important role in OMA formation. Appropriate hydrophobicity of minerals can enhance the formation of OMA. The surface property of minerals can also influence the shape of OMA. Spherical mineral-oil aggregates were frequently formed with hydrophilic minerals while irregular shaped OMA were observed with hydrophobic minerals. The sizes of OMA also increased when the minerals changed from hydrophilic to hydrophobic. The effects of dispersant and mixing energy were also carefully studied. The results showed that dispersant were a dominant factor. When dispersant was applied, effects of other factors became minimal.

Because fire scars provide incomplete records of past fire occurrence at discrete points in space, inferences must be made to reconstruct fire frequency and extent across landscapes using spatial networks of fire-scar samples. Assessing the relative accuracy of fire-scar fire history reconstructions has been hampered due to a lack of empirical comparisons with independent fire history data sources. We carried out such a comparison in a 2780-ha ponderosa pine forest on Mica Mountain in southern Arizona (USA) for the time period 1937--2000. Using documentary records of fire perimeter maps and ignition locations, we compared reconstructions of key spatial and temporal fire regime parameters developed from documentary fire maps and independently collected fire-scar data (n = 60 plots). We found that fire-scar data provided spatially representative and complete inventories of all major fire years (>100 ha) in the study area but failed to detect most small fires. There was a strong linear relationship between the percentage of samples recording fire scars in a given year (i.e., fire-scar synchrony) and total area burned for that year (y = 0.0003x + 0.0087, r super(2) = 0.96). There was also strong spatial coherence between cumulative fire frequency maps interpolated from fire-scar data and ground-mapped fire perimeters. Widely reported fire frequency summary statistics varied little between fire history data sets: fire-scar natural fire rotations (NFR) differed by 25% of study area burned) were identical between data sets (25.5 yr); fire-scar MFIs for all fire years differed by 1.2 yr from documentary records. The known seasonal timing of past fires based on documentary records was furthermore reconstructed accurately by observing intra-annual ring position of fire scars and using knowledge of tree-ring growth phenology in the Southwest. Our results demonstrate clearly that representative landscape-scale fire histories can be reconstructed accurately from spatially distributed fire-scar samples.

We examined how plant community composition, plant diversity, nesting suitability, canopy cover, land use, and fire history affected bee distribution across an open-forest gradient in northwest Indiana, USA, a gradient similar to the historic Midwest United States landscape mosaic. When considered with the other predictors, plant community composition was not a significant predictor of bee community composition. Bee abundance was negatively related to canopy cover and positively to recent fire frequency, bee richness was positively related to plant richness and abundance of potential nesting resources, and bee community composition was significantly related to plant richness, soil characteristics potentially related to nesting suitability, and canopy cover. Thus, bee abundance was predicted by a different set of environmental characteristics than was bee species richness, and bee community composition was predicted, in large part, by a combination of the significant predictors of bee abundance and richness. Differences in bee community composition along the woody vegetation gradient were correlated with relative abundance of oligolectic, or diet specialist, bees. Because oligoleges were rarer than diet generalists and were associated with open habitats, their populations may be especially affected by degradation of open habitats. More habitat-specialist bees were documented for open and forest/scrub habitats than for savanna/woodland habitats, consistent with bees responding to habitats of intermediate woody vegetation density, such as savannas, as ecotones rather than as distinct habitat types. Similarity of bee community composition, similarity of bee abundance, and similarity of bee richness between sites were not significantly related to proximity of sites to each other. Nestedness analysis indicated that species composition in species-poor sites was not merely a subset of species composition at richer sites. The lack of significant proximity or nestedness effects suggests that factors at a small spatial scale strongly influence bees' use of sites. The findings indicate that patterns of plant diversity, nesting resource availability, recent fire, and habitat shading, present at the scale of a few hundred meters, are key determinants of bee community patterns in the mosaic open-savanna-forest landscape.

Similar to the native mysid Mysis diluviana, Hemimysis exhibits a diel vertical migration pattern but generally inhabits shallower and warmer waters than M. diluviana. Because basic information on the distribution, habitat use, and biology of Hemimysis in the Great Lakes is scarce, the potential for food web disruption by Hemimysis cannot easily be predicted. Preliminary observations indicate widespread invasion of Hemimysis in Lake Ontario. In this study, we confirm the presence of Hemimysis at sites spanning the northern and southern shores of Lake Ontario and the presence of the individuals during winter months. In one horizontal tow in November 2007, over 26,000 individuals were collected with a length range of 4.4 to 9.0 mm and an average caloric density of 611 cal/g wet weight. The most effective methods for sampling Hemimysis were horizontal tows with either a zooplankton net in the water column or a benthic sled near the lake bottom. Although more quantitative data on the life history and distribution of this species is necessary, our preliminary observations support the prediction that the potential for Hemimysis to impact the nearshore food web in Lake Ontario appears high.

Under controlled laboratory conditions, we subjected small nongame cyprinids, ictalurids, and percids to a wide range of voltages and waveforms to examine potential harmful effects. Fish were treated with power levels distributed uniformly between the thresholds required to immobilize game fish and also were subjected multiple times to those thresholds to simulate the range of conditions that might exist in a heterogeneous electrical field formed during electrofishing in field situations. Across waveforms and species, the incidence of hemorrhages averaged 2% (range = 0-20%), the incidence of spinal injuries averaged 6% (range = 0-30%), and mortality averaged 16% (range = 0-90%). Continuous DC was generally less harmful than pulsed-DC waveforms; hemorrhages and spinal injuries tended to increase with high pulse frequencies, and mortalities tended to increase with low pulse frequencies. Ambiguities in the results were apparent, suggesting that some species may experience extensive harm, whereas others may not. Given the potential to harm numerically small populations and populations of imperiled species, we suggest (1) expanded efforts to overcome the power limitations that prevent effective use of continuous-DC electrofishing in many field situations and (2) pilot studies at geographic locations where numerically small populations of nongame species may be a concern.

It is a primary driver of physiological rates and many abiotic processes. However, despite extensive research and measurements, synoptic estimates of water temperature are not available for most regions, limiting our ability to make systemwide and large-scale assessments of aquatic resources or estimates of aquatic species abundance and biodiversity. We used subwatershed averaging of point temperature measurements and associated multiscale landscape habitat conditions from over 3,300 lotic sites throughout New York State to develop and train artificial neural network models. Separate models predicting water temperature (in cold, cool, and warm temperature classes) within small catchment-stream order groups were developed for four modeling units, which together encompassed the entire state. Water temperature predictions were then made for each stream segment in the state. All models explained more than 90% of data variation. Elevation, riparian forest cover, landscape slope, and growing degree-days were among the most important model predictors of water temperature classes. Geological influences varied among regions. Predicted temperature distributions within stream networks displayed patterns of generally increasing temperature downstream but were patchy due to the averaging of water temperatures within stream size-classes of small drainages. Models predicted coldwater streams to be most numerous and warmwater streams to be generally associated with the largest rivers and relatively flat agricultural areas and urban areas. Model predictions provide a complete, georeferenced map of summer daytime mean stream temperature potential throughout New York State that can be used for planning and assessment at spatial scales from the stream segment class to the entire state.

The mean depth of capture of the shallow and deep benthic guilds initially exhibited a trend toward capture in shallower water, switched to a trend toward capture in deeper water in 1991, and changed back to a trend toward capture in shallower water in 2001-2002. Species in the pelagic guild showed a similar pattern, but the initial change point occurred in 1981 for this guild. Individual species in these guilds showed variable patterns of depth distribution, but a feature common to all guilds and all pelagic and deep benthic species was a change to a trend toward capturing fish in shallower water that occurred nearly simultaneously (1999-2002). These common trends suggest that large-scale factors are affecting the habitat use of offshore demersal fish species in Lake Huron. The depth distributions of the three guilds have converged in recent years, indicating that the locations of suitable habitat for offshore demersal fishes may be changing. Our results indicate that the benthic ecology of the western main basin of Lake Huron is undergoing profound changes across a large spatial scale that are affecting the habitat use of offshore demersal fishes. We suggest that these changes are related to recent invasions of exotic species.

The two habitats present different swimming challenges with respect to water flow, foraging strategy, habitat complexity, and predation level. We present morphological data from three riverine and three lake-type populations in southwest Alaska. Using multivariate analyses conducted via geometric morphometrics, we determine population- and habitat-specific body shape. As predicted, riverine sockeye salmon have a more robust body shape, whereas lake-type sockeye salmon have a more streamlined body shape. In particular, we found differences in caudal peduncle depth (riverine deeper), eye size (riverine larger), and overall body depth (riverine deeper). One lake-type population did not follow the predicted pattern, exhibiting an overall exaggerated riverine body shape. Differences between the habitats in terms of predation, complexity, and foraging ecology are probably drivers of these differences. Allometry differed between life history types, suggesting that there are habitat-specific developmental differences.

A potential method of rehabilitating these systems is the addition of sediment-slurries to increase marsh surface elevation, thus ameliorating effects of excessive inundation. Although this technique is growing in popularity, the restoration of ecological function after sediment addition has received little attention. To determine if sediment subsidized salt marshes are functionally equivalent to natural marshes, we examined above- and belowground primary production in replicated restored marshes receiving four levels of sediment addition (29-42 cm North American Vertical Datum of 1988 [NAVD 88]) and in degraded and natural ambient marshes (4-22 cm NAVD 88). Moderate intensities of sediment-slurry addition, resulting in elevations at the mid to high intertidal zone (29-36 cm NAVD 88), restored ecological function to degraded salt marshes. Sediment additions significantly decreased flood duration and frequency and increased bulk density, resulting in greater soil drainage and redox potential and significantly lower phytotoxic sulfide concentrations. However, ecological function in the restored salt marsh showed a sediment addition threshold that was characterized by a decline in primary productivity in areas of excessive sediment addition and high elevation (>36 cm NAVD 88). Hence, the addition of intermediate levels of sediment to submerging salt marshes increased marsh surface elevation, ameliorated impacts of prolonged inundation, and increased primary productivity. However, too much sediment resulted in diminished ecological function that was equivalent to the submerged or degraded system.

Here, we report the results of a detailed study during water year 2007 (October 1, 2006 to September 30, 2007) in the major rivers of the Yellowstone Plateau Volcanic Field (YPVF) which hosts Earth's largest "restless" caldera and over 10,000 thermal features. The chemical compositions of rivers that drain thermal areas in the YPVF differ significantly from the compositions of rivers that drain non-thermal areas. There are large seasonal variations in river chemistry and solute flux, which increases with increasing water discharge. The river chemistry and discharge data collected periodically over an entire year allow us to constrain the annual solute fluxes and to distinguish between low-temperature weathering and hydrothermal flux components. The TDS flux from Yellowstone Caldera in water year 2007 was 93t/km2/year. Extensive magma degassing and hydrothermal interaction with rocks accounts for at least 82% of this TDS flux, 83% of the cation flux and 72% of the HCO3 a flux. The low-temperature chemical weathering rate (17t/km2/year), calculated on the assumption that all the Cla is of thermal origin, could include a component from low-temperature hydrolysis reactions induced by CO2 ascending from depth rather than by atmospheric CO2. Although this uncertainty remains, the calculated low-temperature weathering rate of the young rhyolitic rocks in the Yellowstone Caldera is comparable to the world average of large watersheds that drain also more soluble carbonates and evaporates but is slightly lower than calculated rates in other, less-silicic volcanic regions. Long-term average fluxes at Yellowstone are likely ~20% higher than those in the abnormally dry water year 2007, but the protocol used in this study can be easily adaptable to track future changes in low-temperature weathering and hydrothermal flux components, which could provide better monitoring of magmatic unrest.

Ultimately, this integrated simulator will be used as a means to organize information, illustrate potential system responses, and facilitate communication within a participatory modeling framework. Initial results show the potential system response to different zoning policy scenarios in terms of the spatial patterns of development, which is referred to as urban form, and consequent impacts on groundwater levels. These results illustrate how the integrated simulator is capable of representing the complexity of the system. From a groundwater modeling perspective, the most important aspect of the integration is that the simulator generates stresses on the groundwater system within the simulation in contrast to the traditional approach that requires the user to specify the stresses through time.

Based on the premise that the worth of data increases in proportion to its ability to reduce the uncertainty of key model predictions, the methodology can be used to compare the worth of different data types, gathered at different locations within study areas of arbitrary complexity. The method is applied to a hypothetical nonlinear, variable density numerical model of salt and heat transport. The relative utilities of temperature and concentration measurements at different locations within the model domain are assessed in terms of their ability to reduce the uncertainty associated with predictions of movement of the salt water interface in response to a decrease in fresh water recharge. In order to test the sensitivity of the method to nonlinear model behavior, analyses were repeated for multiple realizations of system properties. Rankings of observation worth were similar for all realizations, indicating robust performance of the methodology when employed in conjunction with a highly nonlinear model. The analysis showed that while concentration and temperature measurements can both aid in the prediction of interface movement, concentration measurements, especially when taken in proximity to the interface at locations where the interface is expected to move, are of greater worth than temperature measurements. Nevertheless, it was also demonstrated that pairs of temperature measurements, taken in strategic locations with respect to the interface, can also lead to more precise predictions of interface movement.

Capture that results in a loss of water in streams, rivers, and wetlands now is a concern in many parts of the United States. Hydrologists commonly use analytical and numerical approaches to study temporal variations in sources of water to wells for select points of interest. Much can be learned about coupled surface/groundwater systems, however, by looking at the spatial distribution of theoretical capture for select times of interest. Development of maps of capture requires (1) a reasonably well-constructed transient or steady state model of an aquifer with head-dependent flow boundaries representing surface water features or evapotranspiration and (2) an automated procedure to run the model repeatedly and extract results, each time with a well in a different location. This paper presents new methods for simulating and mapping capture using three-dimensional groundwater flow models and presents examples from Arizona, Oregon, and Michigan.

The most recent version of SEAWAT, called SEAWAT Version 4, includes new capabilities to represent simultaneous multispecies solute and heat transport. To test the new features in SEAWAT, the laboratory experiment of Henry and Hilleke (1972) was simulated. Henry and Hilleke used warm fresh water to recharge a large sand-filled glass tank. A cold salt water boundary was represented on one side. Adjustable heating pads were used to heat the bottom and left sides of the tank. In the laboratory experiment, Henry and Hilleke observed both salt water and fresh water flow systems separated by a narrow transition zone. After minor tuning of several input parameters with a parameter estimation program, results from the SEAWAT simulation show good agreement with the experiment. SEAWAT results suggest that heat loss to the room was more than expected by Henry and Hilleke, and that multiple thermal convection cells are the likely cause of the widened transition zone near the hot end of the tank. Other computer programs with similar capabilities may benefit from benchmark testing with the Henry and Hilleke laboratory experiment.

This allows for more complete analysis of conjunctive use water-resource systems than previously possible with MODFLOW by combining relevant aspects of the landscape with the groundwater and surface water components. This analysis is accomplished using distributed cell-by-cell supply-constrained and demand-driven components across the landscape within 'water-balance subregions' comprised of one or more model cells that can represent a single farm, a group of farms, or other hydrologic or geopolitical entities. Simulation of micro-agriculture in the Pajaro Valley and macro-agriculture in the Central Valley are used to demonstrate the utility of MF-FMP. For Pajaro Valley, the simulation of an aquifer storage and recovery system and related coastal water distribution system to supplant coastal pumpage was analyzed subject to climate variations and additional supplemental sources such as local runoff. For the Central Valley, analysis of conjunctive use from different hydrologic settings of northern and southern subregions shows how and when precipitation, surface water, and groundwater are important to conjunctive use. The examples show that through MF-FMP's ability to simulate natural and anthropogenic components of the hydrologic cycle, the distribution and dynamics of supply and demand can be analyzed, understood, and managed. This analysis of conjunctive use would be difficult without embedding them in the simulation and are difficult to estimate a priori.

Stream Water Quality Trends Coinciding with the Return of Fish AN - 759321616; 13757044 AB - Acidic mine drainage (AMD) from legacy anthracite mines has contaminated Swatara Creek in eastern Pennsylvania. Intermittently collected base-flow data for 1959-1986 indicate that fish were absent immediately downstream from the mined area where pH ranged from 3.5 to 7.2 and concentrations of sulfate, dissolved iron, and dissolved aluminum were as high as 250, 2.0, and 4.7mg/L, respectively. However, in the 1990s, fish returned to upper Swatara Creek, coinciding with the implementation of AMD treatment (limestone drains, limestone diversion wells, limestone sand, constructed wetlands) in the watershed. During 1996-2006, as many as 25 species of fish were identified in the reach downstream from the mined area, with base-flow pH from 5.8 to 7.6 and concentrations of sulfate, dissolved iron, and dissolved aluminum as high as 120, 1.2, and 0.43mg/L, respectively. Several of the fish taxa are intolerant of pollution and low pH, such as river chub (Nocomis micropogon) and longnose dace (Rhinichthys cataractae). Cold-water species such as brook trout (Salvelinus fontinalis) and warm-water species such as rock bass (Ambloplites rupestris) varied in predominance depending on stream flow and stream temperature. Storm flow data for 1996-2007 indicated pH, alkalinity, and sulfate concentrations decreased as the stream flow and associated storm-runoff component increased, whereas iron and other metal concentrations were poorly correlated with stream flow because of hysteresis effects (greater metal concentrations during rising stage than falling stage). Prior to 1999, pH<5.0 was recorded during several storm events; however, since the implementation of AMD treatments, pH has been maintained near neutral. Flow-adjusted trends for 1997-2006 indicated significant increases in calcium; decreases in hydrogen ion, dissolved aluminum, dissolved and total manganese, and total iron; and no change in sulfate or dissolved iron in Swatara Creek immediately downstream from the mined area. The increased pH and calcium from limestone in treatment systems can be important for mitigating toxic effects of dissolved metals. Thus, treatment of AMD during the 1990s improved pH buffering, reduced metals transport, and helped to decrease metals toxicity to fish.

Performance of Treatment Systems AN - 759320888; 13757045 AB - A variety of passive and semi-passive treatment systems were constructed by state and local agencies to neutralize acidic mine drainage (AMD) and reduce the transport of dissolved metals in the upper Swatara Creek Basin in the Southern Anthracite Coalfield in eastern Pennsylvania. To evaluate the effectiveness of selected treatment systems installed during 1995-2001, the US Geological Survey collected water-quality data at upstream and downstream locations relative to each system eight or more times annually for a minimum of 3years at each site during 1996-2007. Performance was normalized among treatment types by dividing the acid load removed by the size of the treatment system. For the limestone sand, open limestone channel, oxic limestone drain, anoxic limestone drain (ALD), and limestone diversion well treatment systems, the size was indicated by the total mass of limestone; for the aerobic wetland systems, the size was indicated by the total surface area of ponds and wetlands. Additionally, the approximate cost per tonne of acid treated over an assumed service life of 20years was computed. On the basis of these performance metrics, the limestone sand, ALD, oxic limestone drain, and limestone diversion wells had similar ranges of acid-removal efficiency and cost efficiency. However, the open limestone channel had lower removal efficiency and higher cost per ton of acid treated. The wetlands effectively attenuated metals transport but were relatively expensive considering metrics that evaluated acid removal and cost efficiency. Although the water-quality data indicated that all treatments reduced the acidity load from AMD, the ALD was most effective at producing near-neutral pH and attenuating acidity and dissolved metals. The diversion wells were effective at removing acidity and increasing pH of downstream water and exhibited unique potential to treat moderate to high flows associated with storm flow conditions.

Federal and state agencies currently issue warnings of the potential for shallow, rapidly moving landslides and debris flows in a few areas along the Pacific coast and for areas affected by Atlantic hurricanes. However, these agencies generally lack resources needed to provide continuous support or to expand services to other areas. Precipitation thresholds that form the basis of landslide warning systems now exist for a few areas of the USA, but the threshold rainfall amounts and durations vary over three orders of magnitude nationwide and over an order of magnitude across small geographic areas such as a county. Antecedent moisture conditions also have a significant effect, particularly in areas that have distinct wet and dry seasons. Early warnings of shallow landslides that include specific information about affected areas, probability of landslide occurrence, and expected timing are technically feasible as illustrated by a case study from the Seattle, WA area. The four-level warning scheme (Null, Outlook, Watch, Warning) defined for Seattle is based on observed or predicted exceedance of a cumulative precipitation threshold and a rainfall intensity-duration threshold combined with real-time monitoring of soil moisture. Based on analysis of historical data, threshold performance varies according to precipitation characteristics, and threshold exceedance corresponds to a given probability of landslide occurrence. Experience in Seattle during December 2004 and January 2005 illustrates some of the challenges of providing landslide early warning on the USA West Coast.

AN - 754898096; 13528733 AB - Summary1. Latitudinal variation in clutch sizes of birds is a well described, but poorly understood pattern. Many hypotheses have been proposed, but few have been experimentally tested, and none have been universally accepted by researchers.2. The nest size hypothesis posits that higher nest predation in the tropics favours selection for smaller nests and thereby constrains clutch size by shrinking available space for eggs and-or nestlings in the nest. We tested this hypothesis with an experiment in a tropical forest and a comparative study between temperate and tropical field sites.3. Specifically, we tested if: (i) predation increased with nest size; (ii) tropical birds had smaller nests controlled for body size; and (iii) clutch size was explained by nest size controlled for body size.4. Experimental swapping of nests of different sizes showed that nest predation increased with nest size in the tropical site. Moreover, nest predation rates were higher in species with larger nests in both sites. However, nest size, corrected for body mass and phylogeny, did not differ between sites and was not related to clutch size between sites.5. Hence, nest predation can exert selection on nest size as predicted by the hypothesis. Nest size increased with adult body mass, such that adult size might indirectly influence reproductive success through effects on nest size and nest predation risk. Ultimately, however, selection from nest predation on nest size does not explain the smaller clutch sizes typical of the tropics.

We investigated the effect of predation on two different white perch Morone americana populations (stunted and nonstunted) by examining the stomach contents of piscivorous fishes. White perch and gizzard shad dominated piscivore diets in Branched Oak Lake, whereas white perch dominated piscivore diets in Pawnee Lake. White perch consumed in the stunted population (Branched Oak Lake) were larger and older than white perch consumed in the nonstunted population (Pawnee Lake). Many of the consumed white perch in the stunted population were sexually mature and had the opportunity to spawn at least once. In contrast, all of the consumed white perch in the nonstunted population were sexually immature. Predation may have reinforced the stunting of white perch in Branched Oak Lake through removal of the largest, oldest individuals.

Recruitment of burbot (Lota lota L.) in Lake Erie: an empirical modelling approach. Ecology of Freshwater Fish 2010: 19: 326-337. Published 2010. This article is a US Government work and is in the public domain in the USAAbstract - World-wide, many burbot Lota lota (L.) populations have been extirpated or are otherwise in need of conservation measures. By contrast, burbot made a dramatic recovery in Lake Erie during 1993-2001 but declined during 2002-2007, due in part to a sharp decrease in recruitment. We used Akaike's Information Criterion to evaluate 129 linear regression models that included all combinations of one to seven ecological indices as predictors of burbot recruitment. Two models were substantially supported by the data: (i) the number of days in which water temperatures were within optimal ranges for burbot spawning and development combined with biomass of yearling and older (YAO) yellow perch Perca flavescens (Mitchill); and (ii) biomass of YAO yellow perch. Warmer winter water temperatures and increases in yellow perch biomass were associated with decreases in burbot recruitment. Continued warm winter water temperatures could result in declines in burbot recruitment, particularly in the southern part of the species' range.

Currently, little is known about the microbiology or chemistry of permafrost soils that may affect its decomposition once soils thaw. We tested the hypothesis that low microbial abundances and activities in permafrost soils limit decomposition rates compared with active layer soils. We examined active layer and permafrost soils near Fairbanks, AK, the Yukon River, and the Arctic Circle. Soils were incubated in the lab under aerobic and anaerobic conditions. Gas fluxes at -5 and 5 degree C were measured to calculate temperature response quotients (Q sub(10)). The Q sub(10) was lower in permafrost soils (average 2.7) compared with active layer soils (average 7.5). Soil nutrients, leachable dissolved organic C (DOC) quality and quantity, and nuclear magnetic resonance spectroscopy of the soils revealed that the organic matter within permafrost soils is as labile, or even more so, than surface soils. Microbial abundances (fungi, bacteria, and subgroups: methanogens and Basidiomycetes) and exoenzyme activities involved in decomposition were lower in permafrost soils compared with active layer soils, which, together with the chemical data, supports the reduced Q sub(10) values. CH sub(4) fluxes were correlated with methanogen abundance and the highest CH sub(4) production came from active layer soils. These results suggest that permafrost soils have high inherent decomposability, but low microbial abundances and activities reduce the temperature sensitivity of C fluxes. Despite these inherent limitations, however, respiration per unit soil C was higher in permafrost soils compared with active layer soils, suggesting that decomposition and heterotrophic respiration may contribute to a positive feedback to warming of this eco region.

Despite its potential advantages, one major drawback of traditional mark-resight methodology is that the number of marked individuals in the population available for resighting needs to be known exactly. In real field studies, this can be quite difficult to accomplish. Here we develop a Bayesian model for estimating abundance when sighting data are acquired from distinct sampling occasions without replacement, but the exact number of marked individuals is unknown. By first augmenting the data with some fixed number of individuals comprising a marked "super population," the problem may then be reformulated in terms of estimating the proportion of this marked super population that was actually available for resighting. This then allows the data for the marked population available for resighting to be modeled as random realizations from a binomial logit-normal distribution. We demonstrate the use of our model to estimate the New Zealand robin (Petroica australis) population size in a region of Fiordland National Park, New Zealand. We then evaluate the performance of the proposed model relative to other estimators via a series of simulation experiments. We generally found our model to have advantages over other models when sample sizes are smaller with individually heterogeneous resighting probabilities. Due to limited budgets and the inherent variability between individuals, this is a common occurrence in mark-resight population studies. WinBUGS and R code to carry out these analyses is available from http://www.stat.colostate.edu/~jah/software.

Water quality at three of the least-impaired lakes generally was comparable and also was comparable to water quality from Kansas and Missouri reference lakes and Texas least-impaired lakes. Water quality of one least-impaired lake in the MAP ecoregion was not as good as water quality in other least-impaired lakes in Arkansas or in the three other states: a probable consequence of all lakes in that classification having a designated use as a source of irrigation water. Chemical and physical conditions for all four lake classifications were at times naturally harsh as limnological characteristics changed temporally. As a consequence of allochthonous organic material, oxbow lakes isolated within watersheds comprised of swamps were susceptible to low dissolved oxygen concentrations to the extent that conditions would be limiting to some aquatic biota. Also, pH in lakes in the SCP ecoregion was <6.0, a level exceeding current Arkansas water-quality standards but typical of black water systems. Water quality of the deepest lakes exceeded that of shallow lakes. N/P ratios and trophic state indices may be less effective for assessing water quality for shallow lakes (<2m) than for deep lakes because there is an increased exposure of sediment (and associated phosphorus) to disturbance and light in the former.

These techniques were used to document distinctive magnetic characteristics of grave shafts at three historic cemeteries first surveyed using various near-surface geophysical methods. Tests revealed a low magnetic susceptibility signature that soil magnetic studies indicated was largely related to differential soil compaction associated with the excavation and refilling of grave shafts. Most apparent at depths beyond those reached by soil penetrometers, this magnetic signature offers a way to assess anomalies identified by near-surface techniques that potentially represent graves. At one cemetery, magnetic studies of the interments themselves suggested spatially patterned, magnetically enhanced zones that might also aid in burial identification in certain contexts. While down-hole techniques will not be foolproof, they do provide another geophysical tool that can be used to improve grave detection. Abstract Copyright (2010), Wiley Periodicals, Inc.

An inability to predict population response to future habitat projections is a shortcoming in bird conservation planning. We sought to predict avian response to projections of future forest conditions that were developed from nationwide forest surveys within the Forest Inventory and Analysis (FIA) program. To accomplish this, we evaluated the historical relationship between silvicolous bird populations and FIA-derived forest conditions within 25 ecoregions that comprise the southeastern United States. We aggregated forest area by forest ownership, forest type, and tree size-class categories in county-based ecoregions for 5 time periods spanning 1963-2008. We assessed the relationship of forest data with contemporaneous indices of abundance for 24 silvicolous bird species that were obtained from Breeding Bird Surveys. Relationships between bird abundance and forest inventory data for 18 species were deemed sufficient as predictive models. We used these empirically derived relationships between regional forest conditions and bird populations to predict relative changes in abundance of these species within ecoregions that are anticipated to coincide with projected changes in forest variables through 2040. Predicted abundances of these 18 species are expected to remain relatively stable in over a quarter (27%) of the ecoregions. However, change in forest area and redistribution of forest types will likely result in changed abundance of some species within many ecosystems. For example, abundances of 11 species, including pine warbler (Dendroica pinus), brown-headed nuthatch (Sitta pusilla), and chuck-wills-widow (Caprimulgus carolinensis), are projected to increase within more ecoregions than ecoregions where they will decrease. For 6 other species, such as blue-winged warbler (Vermivora pinus), Carolina wren (Thryothorus ludovicianus), and indigo bunting (Passerina cyanea), we projected abundances will decrease within more ecoregions than ecoregions where they will increase.

NLCD 2001 is widely used as a baseline for national land cover and impervious cover conditions. To enable the updating of this database in an optimal manner, methods are designed to be accomplished by individual Landsat scene. Using conservative change thresholds based on land cover classes, areas of change and no-change were segregated from change vectors calculated from normalized Landsat scenes from 2001 and 2006. By sampling from NLCD 2001 impervious surface in unchanged areas, impervious surface predictions were estimated for changed areas within an urban extent defined by a companion land cover classification. Methods were developed and tested for national application across six study sites containing a variety of urban impervious surface. Results show the vast majority of impervious surface change associated with urban development was captured, with overall RMSE from 6.86 to 13.12% for these areas. Changes of urban development density were also evaluated by characterizing the categories of change by percentile for impervious surface. This prototype method provides a relatively low cost, flexible approach to generate updated impervious surface using NLCD 2001 as the baseline.

A proposed widening plan for I-93 has raised concerns over further increases in chloride. As part of this effort, road-salt-contaminated groundwater discharge was mapped with terrain electrical conductivity (EC) electromagnetic (EM) methods in the fall of 2006 to identify potential sources of chloride during base-flow conditions to a small stream, Policy Brook. Three different EM meters were used to measure different depths below the streambed (ranging from 0 to 3 m). Results from the three meters showed similar patterns and identified several reaches where high EC groundwater may have been discharging. Based on the delineation of high (up to 350 mmhos/m) apparent terrain EC, seven-streambed piezometers were installed to sample shallow groundwater. Locations with high specific conductance in shallow groundwater (up to 2630 mmhos/m) generally matched locations with high streambed (shallow subsurface) terrain EC. A regression equation was used to convert the terrain EC of the streambed to an equivalent chloride concentration in shallow groundwater unique for this site. Utilizing the regression equation and estimates of one-dimensional Darcian flow through the streambed, a maximum potential groundwater chloride load was estimated at 188 Mg of chloride per year. Changes in chloride concentration in stream water during streamflow recessions showed a linear response that indicates the dominant process affecting chloride is advective flow of chloride-enriched groundwater discharge.

Therefore, understanding their spatial use in this environment is a priority for conservation efforts. We studied the fine scale daily movements and habitat use of East Pacific green turtles (Chelonia mydas) at Laguna San Ignacio, a shallow coastal lagoon in Baja California Sur, Mexico where sea turtles are subject to high levels of gillnet bycatch and directed hunting. Six turtles ranging from 44.6 to 83.5cm in straight carapace length were tracked for short deployments (1 to 6 d) with GPS-VHF telemetry. Turtles were active throughout diurnal, nocturnal, and crepuscular periods. Although they moved greater total distances during daytime, their speed of travel and net displacement remained consistent throughout 24-h periods. A positive selection for areas of seagrass and moderate water depth (5 to 10m) was determined using Ivlev's electivity index, with neutral selection for shallow water (10m). Turtles exhibited two distinct behavioral movement patterns: circular movements with high fidelity to the capture-release location and meandering movements with low fidelity to the capture-release location. Our results indicate that green turtles were active throughout the diel cycle while traveling large distances and traversing multiple habitats over short temporal scales.

Our study was designed to evaluate a population endpoint (egg production) in conjunction with histological (e.g., gonad development) and biochemical (e.g., hormone production) phenotypes associated with atrazine exposure in fathead minnows. Adult virgin breeding groups of 1 male and 2 females were exposed to nominal concentrations of 0, 0.5, 5.0, and 50 mu g/L of atrazine in a flow-through diluter for 14 or 30 days. Total egg production was lower (19-39%) in all atrazine-exposed groups as compared to the controls. The decreases in cumulative egg production of atrazine treated fish were significant by 17-20 days of exposure. Reductions in egg production in atrazine treatment groups were most attributable to reduced numbers of spawning events with increased atrazine exposure concentrations. Gonad abnormalities were observed in both male and female fish of atrazine-exposed fish. Our results also indicate that atrazine reduces egg production through alteration of final maturation of oocytes. The reproductive effects observed in this study warrant further investigation and evaluation of the potential risks posed by atrazine, particularly feral populations of fish from streams in agricultural areas with high use of this herbicide.

The effect of dissolved organic matter (DOM) isolated from natural waters on reactions between mercury(II) (Hg) and sulfide (S(-II)) to form HgS sub((s)) nanoparticles across a range of Hg and S(-II) concentrations was investigated. Hg was equilibrated with DOM, after which S(-II) was added. Dissolved Hg (Hg sub(aq)) was periodically quantified using ultracentrifugation and chemical analysis following the addition of S(-II). Particle size and identity were determined using dynamic light scattering and X-ray absorption spectroscopy. S(-II) reacts with Hg to form 20 to 200 nm aggregates consisting of 1-2 nm HgS sub((s)) subunits that are more structurally disordered than metacinnabar in the presence of 2 x 10 super(-9) to 8 x 10 super(-6) M Hg and 10 (mg C) L super(-1) DOM. Some of the HgS sub((s)) nanoparticle aggregates are subsequently dissolved by DOM and (re)precipitated by S(-II) over periods of hours to days. At least three fractions of Hg-DOM species were observed with respect to reactivity toward S(-II): 0.3 kmol reactive Hg per mmol C (60 percent), 0.1 kmol per mmol C (20 percent) that are kinetically hindered, and another 0.1 kmol Hg per mmol C (20 percent) that are inert to reaction with S(-II). Following an initial S(-II)-driven precipitation of HgS sub((s)), HgS sub((s)) was dissolved by DOM or organic sulfur compounds. HgS sub((s)) formation during this second phase was counterintuitively favored by lower S(-II) concentrations, suggesting surface association of DOM moieties that are less capable of dissolving HgS sub((s)). DOM partially inhibits HgS sub((s)) formation and mediates reactions between Hg and S(-II) such that HgS sub((s)) is susceptible to dissolution. These findings indicate that Hg accessibility to microorganisms could be controlled by kinetic (intermediate) species in the presence of S(-II) and DOM, undermining the premise that equilibrium Hg species distributions should correlate to the extent or rate of Hg methylation in soils and sediments.

Our objectives were to synthesize the results of these studies and suggest methodologies to (1) monitor regional trends in nitrate concentration in undisturbed 1st order watersheds and (2) reduce nitrate loads in streams draining agricultural watersheds. Our review reveals that undisturbed headwater watersheds have been shown to be very retentive of nitrogen, but the importance of biogeochemical and hydrological riparian zone processes in retaining nitrogen in these watersheds has not been demonstrated as it has for agricultural watersheds. An understanding of the role of the riparian zone in nitrate attenuation in undisturbed watersheds is crucial because these watersheds are increasingly subject to stressors, such as changes in land use and climate, wildfire, and increases in atmospheric nitrogen deposition. In general, understanding processes controlling the concentration and flux of nitrate is critical to identifying and mapping the vulnerability of watersheds to water quality changes due to a variety of stressors. In undisturbed and agricultural watersheds we propose that understanding the importance of riparian zone processes in 2nd order and larger watersheds is critical. Research is needed that addresses the relative importance of how the following sources of nitrate along any given stream reach might change as watersheds increase in size and with flow: (1) inputs upstream from the reach, (2) tributary inflow, (3) water derived from the riparian zone, (4) groundwater from outside the riparian zone (intermediate or regional sources), and (5) in-stream (hyporheic) processes.

For 2 decades, desert tortoise Gopherus agassizii populations have declined, yet quantitative evidence regarding the causes of declines is scarce. In 2005, Ft. Irwin National Training Center, California, USA, implemented a translocation project including 2 yr of baseline monitoring of desert tortoises. Unusually high predation on tortoises was observed after translocation occurred. We conducted a retrospective analysis of predation and found that translocation did not affect the probability of predation: translocated, resident, and control tortoises all had similar levels of predation. However, predation rates were higher near human population concentrations, at lower elevation sites, and for smaller tortoises and females. Furthermore, high mortality rates were not limited to the National Training Center. In 2008, elevated mortality (as high as 43%) occurred throughout the listed range of the desert tortoise. Although no temporal prey base data are available for analysis from any of the study sites, we hypothesize that low population levels of typical coyote Canis latrans prey (i.e. jackrabbits Lepus californicus and other small animals) due to drought conditions influenced high predation rates in previous years. Predation may have been exacerbated in areas with high levels of subsidized predators. Many historical reports of increased predation, and our observation of a range-wide pattern, may indicate that high predation rates are more common than generally considered and may impact recovery of the desert tortoise throughout its range.

Concentrations of water soluble Fe, Cu, and Zn determined from a 1:20 deionized water leachate of the ash were sufficient to provide short-term fertilization of the surface ocean. The 2008 pyroclastic deposits were thicker in concavities at bases of steeper slopes and thinner on steep slopes and ridge crests. By summer 2009, secondary erosion had exposed the pre-eruption soils along gulley walls and in gully bottoms on the southern and eastern slopes, respectively. Topographic and microtopographic position altered the depositional patterns of the pyroclastic flows and resulted in pre-eruption soils being buried by as little as 1m of ash. The different erosion patterns gave rise to three surfaces on which future ecosystems will likely develop: largely pre-eruptive soils; fresh pyroclastic deposits influenced by shallowly buried, pre-eruptive soil; and thick (>1m) pyroclastic deposits. As expected, the chemical composition differed between the pyroclastic deposits and the pre-eruptive soils. Pre-eruptive soils hold stocks of C and N important for establishing biota that are lacking in the fresh pyroclastic deposits. The pyroclastic deposits are a source for P and K but have negligible nutrient holding capacity, making these elements vulnerable to leaching loss. Consequently, the pre-eruption soils may also represent an important long-term P and K source.

Gully erosion has removed 300,000 to 600,000m3 of mostly fine-grained volcanic sediment from the flanks of the volcano and much of this has reached the ocean. Sediment yield estimates from two representative drainage basins on the south and west flanks of the volcano, with drainage areas of 0.7 and 0.5km2, are about 104m3km-2yr-1 and are comparable to sediment yields documented at other volcanoes affected by recent eruptive activity. Estimates of the retreat of coastal cliffs also made from analysis of satellite images indicate average annual erosion rates of 80 to 140myr-1. If such rates persist it could take 3-5years for wave erosion to reach the pre-eruption coastline, which was extended seaward about 400m by the accumulation of erupted volcanic material. As of 13 September 2009, the date of the most recent satellite image of the island, the total volume of material eroded by wave action was about 106m3. We did not investigate the distribution of volcanic sediment in the near shore ocean around Kasatochi Island, but it appears that erosion and sediment dispersal in the nearshore environment will be greatest during large storms when the combination of high waves and rainfall runoff are most likely to coincide.

ER - TY - JOUR T1 - Spatial Distribution of Drifting Pallid Sturgeon Larvae in the Missouri River Inferred from Two Net Designs and Multiple Sampling Locations AN - 839693829; 13851356 AB - Nearly 430,000 larval pallid sturgeon Scaphirhynchus albus (5-13 d posthatch) were released in the Missouri River and allowed to free-drift for 5.7 km and then were sampled at a river bend by boats positioned on the inside-bend, inside-bend channel border, mid-channel, and outside-bend locations of the channel. Boats were rigged with conical nets and rectangle nets designed to sample for drifting pallid sturgeon larvae along the bottom and at the surface of the river to address three objectives: (1) examine the vertical drift behavior of larvae; (2) compare numbers, concentrations, and lengths of larvae between conical and rectangle nets; and (3) examine the lateral distribution of free-drifting larvae. The vertical distribution of larvae was not uniform as nearly all larvae (.98%) were sampled in nets fished on the bottom, and larval concentrations (expressed as larvae/m super(3)) were greater in bottom-fished nets. Large-opening rectangle nets (0.375 m super(2)) fished on the bottom sampled greater numbers of larvae than small-opening conical nets (0.196 m super(2)) fished on the bottom; however, larval concentrations were similar between the two net designs. Numbers and concentrations of larvae differed among lateral sampling locations and increased from the inside-bend location to the outside-bend location. Lengths of sampled larvae were similar between net designs and vertical locations in the water column, but larvae sampled at the mid-channel location were slightly smaller than larvae sampled at other lateral locations. These results serve as a guide for sampling larval pallid sturgeon in large rivers. Specifically, sampling adjacent to the bottom in the high-velocity thalweg of the channel maximizes the likelihood of collecting larvae and quantifying numbers of drifting larvae of this federally endangered species.

We tested the prediction that the ecological integrity of streams would provide an indicator of human cancer mortality rates in West Virginia, USA. We characterized ecological integrity using an index of benthic macroinvertebrate community structure (West Virginia Stream Condition Index, SCI) and quantified human cancer mortality rates using county-level data from the Centers for Disease Control and Prevention. Regression and spatial analyses revealed significant associations between ecological integrity and public health. SCI was negatively related to age-adjusted total cancer mortality per 100,000 people. Respiratory, digestive, urinary, and breast cancer rates increased with ecological disintegrity, but genital and oral cancer rates did not. Smoking, poverty, and urbanization were significantly related to total cancer mortality, but did not explain the observed relationships between ecological integrity and cancer. Coal mining was significantly associated with ecological disintegrity and higher cancer mortality. Spatial analyses also revealed cancer clusters that corresponded to areas of high coal mining intensity. Our results demonstrated significant relationships between ecological integrity and human cancer mortality in West Virginia, and suggested important effects of coal mining on ecological communities and public health. Assessments of ecological integrity therefore may contribute not only to monitoring goals for aquatic life, but also may provide valuable insights for human health and safety.

Approximately 260 million gallons of the water and coal slurry discharged from two underground mine portals and affected over 75 miles of streams in Kentucky and West Virginia. As a result of this and several other breakthroughs over just half a decade, the U.S. Office of Surface Mining Reclamation and Enforcement (OSM) and other institutions undertook investigations to assess the causes of the events, the potential for additional breakthroughs in the future, and available methods for preventing them. In addition to needed improvements in the design, construction, and inspection of the facilities, the studies have addressed issues pertaining to the flow characteristics of refuse slurry, not only in impoundments still receiving pumped slurry, but also in "idle" and reclaimed facilities. Related questions concern: (1) the effects on breakthrough potential of the impoundment abandonment process and construction of slurry cells on top of capped structures; and (2) appropriate measures and available methods that may be used to ensure that underground mines adjacent to or underlying impoundments are known and accurately located. Current information on the engineering properties of coal refuse in existing facilities provides no assurance against fine refuse flowability during any stage in the impoundment construction and reclamation process or after reclamation has been completed. Due to this uncertainty, thorough site investigations and conservative measures in design, construction, reclamation, and quality control are of paramount importance.

For example, various metacommunity theories are based on differences in the relative contributions of dispersal of species among local communities and interactions of species within local communities. Interestingly, metacommunity theories continue to be advanced without much empirical validation. Part of the problem is that statistical models used to analyze typical survey data either fail to specify ecological processes with sufficient complexity or they fail to account for errors in detection of species during sampling. In this paper, we describe a statistical modeling framework for the analysis of metacommunity dynamics that is based on the idea of adopting a unified approach, multispecies occupancy modeling, for computing inferences about individual species, local communities of species, or the entire metacommunity of species. This approach accounts for errors in detection of species during sampling and also allows different metacommunity paradigms to be specified in terms of species- and location-specific probabilities of occurrence, extinction, and colonization: all of which are estimable. In addition, this approach can be used to address inference problems that arise in conservation ecology, such as predicting temporal and spatial changes in biodiversity for use in making conservation decisions. To illustrate, we estimate changes in species composition associated with the species-specific phenologies of flight patterns of butterflies in Switzerland for the purpose of estimating regional differences in biodiversity.

Total drilling depth reached 1285 m below seafloor (mbsf) with 98 percent core recovery for the detailed study of glacier dynamics. With the goal of obtaining complementary information regarding heat flow and permeability, which is vital to understanding the nature of marine hydrogeologic systems, a succession of three temperature logs was recorded over a five-day span to monitor the gradual thermal recovery toward equilibrium conditions. These data were extrapolated to true, undisturbed temperatures, and they define a linear geothermal gradient of 76.7 K/km from the seafloor to 647 mbsf. Bulk thermal conductivities of the sedimentary rocks were derived from empirical mixing models and density measurements performed on core, and an average value of 1.5 W/mK c 10 percent was determined. The corresponding estimate of heat flow at this site is 115 mW/m super(2). This value is relatively high but is consistent with other elevated heat-flow data associated with the Erebus Volcanic Province. Information regarding the origin and frequency of pathways for subsurface fluid flow is gleaned from drillers' records, complementary geophysical logs, and core descriptions. Only two prominent permeable zones are identified and these correspond to two markedly different features within the rift basin; one is a distinct lithostratigraphic subunit consisting of a thin lava flow and the other is a heavily fractured interval within a single thick subunit.

The water was stored in the aquifer for 438 days, and 2.64 x 10 super(6) m super(3) of water were extracted between July 2007 and February 2008. On the basis of Cl super(-) data, 35% of the injected water was recovered and 65% of the injected water and associated disinfection by-products (DBPs) remained in the aquifer at the end of extraction. About 46.3 kg of total trihalomethanes (TTHM) entered the aquifer with the injected water and 37.6 kg of TTHM were extracted. As much as 44 kg of TTHMs remained in the aquifer at the end of extraction because of incomplete recovery of injected water and formation of THMs within the aquifer by reactions with free-chlorine in the injected water. Well-bore velocity log data collected from the Aquifer Storage Recovery (ASR) well show as much as 60% of the injected water entered the aquifer through a 9 m thick, high-permeability layer within the confined aquifer near the top of the screened interval. Model simulations of ground-water flow near the ASR well indicate that (1) aquifer heterogeneity allowed injected water to move rapidly through the aquifer to nearby monitoring wells, (2) aquifer heterogeneity caused injected water to move further than expected assuming uniform aquifer properties, and (3) physical clogging of high-permeability layers is the probable cause for the observed change in the distribution of borehole flow. Aquifer heterogeneity also enhanced mixing of native anoxic ground water with oxic injected water, promoting removal of THMs primarily through sorption. A 3 to 4-fold reduction in TTHM concentrations was observed in the furthest monitoring well 427 m downgradient from the ASR well, and similar magnitude reductions were observed in depth-dependent water samples collected from the upper part of the screened interval in the ASR well near the end of the extraction phase. Haloacetic acids (HAAs) were completely sorbed or degraded within 10 months of injection.

During 1997, larval drift occurred over a 22 day period when discharge rates were low (mean c s.d. 3.2 plus or minus 0.0 m super(3) s super(-1)). In 1998, larval drift occurred in two separate events over a 40 day period. Discharge was higher during the first larval drift period (19 days; 24.8 plus or minus 1.3 m super(3) s super(-1)) and lower during the second larval drift period (17 days; 7.0 plus or minus 0.9 m super(3) s super(-1)). In 1997, no larval fish were collected at the lowermost transect on the Provo River (nearest Utah Lake), and few larvae >21 days of age were found. During the first drift period of 1998, larval C. liorus were collected at all transects, and mean age of larvae collected between upstream and downstream transects increased by c. 7 days. During the second drift period of 1998, only a few were collected in the lowermost transects, and age did not increase with proximity to the lake. Patterns in catch and age distribution of larval C. liorus in the lower Provo River suggest that recruitment failure occurs during the larval drift period in years with insufficient discharge to transport larvae into the lake.

NHAs seek to integrate environmental objectives with community and economic objectives at regional or landscape scales. NHA designations have increased rapidly in the last 20 years, generating a substantial need for evaluative information about (a) how NHAs work; (b) outcomes associated with the NHA process; and (c) the costs and benefits of investing public moneys into the NHA approach. Qualitative evaluation studies recently conducted at three NHAs have identified the importance of understanding network structure and function in the context of evaluating NHA management effectiveness. This article extends these case studies by examining quantitative network data from each of the sites. The authors analyze these data using both a descriptive approach and a statistically more robust approach known as exponential random graph modeling. Study findings indicate the presence of transitive structures and the absence of three-cycle structures in each of these networks. This suggests that these networks are relatively 'open,' which may be desirable, given the uncertainty of the environments in which they operate. These findings also suggest, at least at the sites reported here, that the NHA approach may be an effective way to activate and develop networks of intersectoral organizational partners. Finally, this study demonstrates the utility of using quantitative network analysis to better understand the effectiveness of protected area management models that rely on partnership networks to achieve their intended outcomes.

Perhaps the most salient example of this trend toward partnerships is the rapid growth and development of national heritage areas (NHAs). Since the first NHA received congressional designation in 1984, NHAs have become an increasingly popular strategy for protecting and managing landscapes. To date, congressional designation has been granted to 49 NHAs, making them one of the fastest growing initiatives involving the NPS. Despite this growth, no prior research has examined the efficacy or effectiveness of the NHA model. This article introduces the NHA concept, while reviewing the literature on evaluation research and its application to protected area management. We then offer an NHA program theory model for evaluating NHAs. The model was developed using a theory-based, process evaluation approach, along with 90 qualitative interviews conducted at three study sites: Blackstone River Valley National Heritage Corridor, MA-RI (BLAC); Delaware and Lehigh National Heritage Corridor, PA (DELE); and Cane River National Heritage Area, LA (CANE). We conclude by discussing the key challenges and implications associated with developing a long-term research agenda for evaluating NHAs.

High latitudes may be particularly sensitive to climate change, however, adequate baselines for these lakes are often lacking. In this study, we couple monitoring, remote sensing, and modeling techniques to generate baseline datasets of lake surface temperature and ice cover in the Alaskan Subarctic and Arctic. No detectable trends were observed during this study period, but a number of interesting patterns were noted among lakes and between regions. The largest Arctic lake was relatively unresponsive to air temperature, while the largest Subarctic lake was very responsive likely because it is fed by glacial runoff. Mean late summer water temperatures were higher than air temperatures with differences ranging from 1.7 to 5.4 degrees C in Subarctic lakes and from 2.4 to 3.2 degrees C in Arctic lakes. The warmest mean summer water temperature in both regions was in 2004, with the exception of Subarctic glacially fed lake that was highest in 2005. Ice-out timing had high coherence within regions and years, typically occurring in late May in Subarctic and in early-July in Arctic lakes. Ice-on timing was more dependent on lake size and depth, often varying among lakes within a region. Such analyses provide an important baseline of lake surface regimes at a time when there is increasing interest in high-latitude water ecosystems and resources during an uncertain climate future.

14132926 AB - Kasatochi Island, the subaerial portion of a small volcano in the western Aleutian volcanic arc, erupted on 7-8 August 2008. Pyroclastic flows and surges swept the island repeatedly and buried most of it and the near-shore zone in decimeters to tens of meters of deposits. Several key seabird rookeries in taluses were rendered useless. The eruption lasted for about 24hours and included two initial explosive pulses and pauses over a 6-hr period that produced ash-poor eruption clouds, a 10-hr period of continuous ash-rich emissions initiated by an explosive pulse and punctuated by two others, and a final 8-hr period of waning ash emissions. The deposits of the eruption include a basal muddy tephra that probably reflects initial eruptions through the shallow crater lake, a sequence of pumiceous and lithic-rich pyroclastic deposits produced by flow, surge, and fall processes during a period of energetic explosive eruption, and a fine-grained upper mantle of pyroclastic-fall and -surge deposits that probably reflects the waning eruptive stage as lake and ground water again gained access to the erupting magma. An eruption with similar impact on the island's environment had not occurred for at least several centuries. Since the 2008 eruption, the volcano has remained quiet other than emission of volcanic gases. Erosion and deposition are rapidly altering slopes and beaches.

It is a high-elevation specialist endemic to the Tibetan Plateau where it prefers alpine meadow and alpine steppe but uses other lower-elevation plains and valleys. It is partial to good grasslands with high diversity of forbs. There have been no systematic estimates of total numbers of P. picticaudata. Populations are currently widespread but have been reduced from historic levels and are vulnerable because of poaching in remote areas and competition with livestock of pastoralists. P. picticaudata is uncommon in zoos and private collections. It is a threatened Class II species in China and considered "Near Threatened" by the International Union for Conservation of Nature and Natural Resources.

15267617 AB - A new method to seal water in silver tubes for use in a TC/EA (thermal conversion/elemental analyzer) reduction unit using a semi-automated sealing apparatus can yield reproducibilities (1 standard deviation) of delta 2H and delta 18O measurements of 1.0ppt and 0.06ppt, respectively. These silver tubes containing reference waters may be preferred for the calibration of H- and O-bearing materials analyzed with a TC/EA reduction unit. The new sealing apparatus employs a computer-controlled stepping motor to produce silver tubes identical in length. The reproducibility of the mass of water sealed in tubes (in a range of 200-400 mu g) can be as good as 1%. Approximately 99% of the sealed silver tubes are satisfactory (leak free). Although silver tubes sealed with reference waters are robust and can be shaken or heated to 110 degree C with no loss of integrity, they should not be frozen because the expansion during the phase transition of water to ice will break the cold seals and all the water will be lost. The tubes should be shipped in insulated containers. This new method eliminates air inclusions and isotopic fractionation of water associated with the loading of water into capsules using a syringe. The method is also more than an order of magnitude faster than preparing water samples in ordinary Ag capsules. Nevertheless, some laboratories may prefer loading water into silver capsules because expensive equipment is not needed, but users of this method are cautioned to apply the necessary corrections for evaporation, back exchange with laboratory atmospheric moisture, and blanks.

In addition to quantifying changes to the spatial and temporal patterns of burned areas, observing variations in severity is the key to studying the impact of changes to the fire regime on carbon cycling, energy budgets, and post-fire succession. Remote sensing indices of fire severity have not consistently been well-correlated with in situ observations of important severity characteristics in Alaskan black spruce stands, including depth of burning of the surface organic layer. The incorporation of ancillary data such as in situ observations and GIS layers with spectral data from Landsat TM/ETM+ greatly improved efforts to map the reduction of the organic layer in burned black spruce stands. Using a regression tree approach, the R 2 of the organic layer depth reduction models was 0.60 and 0.55 (p 200,000ha) fire to identify areas that are potentially vulnerable to a shift in post-fire succession. This application showed that 12% of this fire event experienced fire severe enough to support a change in post-fire succession. We conclude that non-parametric models and ancillary data are useful in the modeling of the surface organic layer fire depth. Because quantitative differences in post-fire surface characteristics do not directly influence spectral properties, these modeling techniques provide better information than the use of remote sensing data alone.

For most of the Arctic, however, there is no existing baseline inventory of shrub canopy cover, as existing maps of Arctic vegetation provide little information about the density of shrub cover at a moderate spatial resolution across the region. Remotely-sensed fractional shrub canopy maps can provide this necessary baseline inventory of shrub cover. In this study, we compare the accuracy of fractional shrub canopy (>0.5m tall) maps derived from multi-spectral, multi-angular, and multi-temporal datasets from Landsat imagery at 30m spatial resolution, Moderate Resolution Imaging SpectroRadiometer (MODIS) imagery at 250m and 500m spatial resolution, and MultiAngle Imaging Spectroradiometer (MISR) imagery at 275m spatial resolution for a 1067km2 study area in Arctic Alaska. The study area is centered at 69AN, ranges in elevation from 130 to 770m, is composed primarily of rolling topography with gentle slopes less than 10A, and is free of glaciers and perennial snow cover. Shrubs >0.5m in height cover 2.9% of the study area and are primarily confined to patches associated with specific landscape features. Reference fractional shrub canopy is determined from in situ shrub canopy measurements and a high spatial resolution IKONOS image swath. Regression tree models are constructed to estimate fractional canopy cover at 250m using different combinations of input data from Landsat, MODIS, and MISR. Results indicate that multi-spectral data provide substantially more accurate estimates of fractional shrub canopy cover than multi-angular or multi-temporal data. Higher spatial resolution datasets also provide more accurate estimates of fractional shrub canopy cover (aggregated to moderate spatial resolutions) than lower spatial resolution datasets, an expected result for a study area where most shrub cover is concentrated in narrow patches associated with rivers, drainages, and slopes. Including the middle infrared bands available from Landsat and MODIS in the regression tree models (in addition to the four standard visible and near-infrared spectral bands) typically results in a slight boost in accuracy. Including the multi-angular red band data available from MISR in the regression tree models, however, typically boosts accuracy more substantially, resulting in moderate resolution fractional shrub canopy estimates approaching the accuracy of estimates derived from the much higher spatial resolution Landsat sensor. Given the poor availability of snow and cloud-free Landsat scenes in many areas of the Arctic and the promising results demonstrated here by the MISR sensor, MISR may be the best choice for large area fractional shrub canopy mapping in the Alaskan Arctic for the period 2000-2009.

Recent rapid growth in Colorado, USA has stressed groundwater supplies in some areas, thereby increasing scrutiny of approximate methods developed there more than 30years ago to estimate consumptive use that are still used today. A foothills residence was studied during a 2-year period to estimate direct and indirect water losses. Direct losses are those from evaporation inside the home, plus any outdoor use. Indirect loss is evapotranspiration (ET) from the residential leach-field in excess of ET from the immediately surrounding terrain. Direct losses were 18.7% of water supply to the home, substantially larger than estimated historically in Colorado. A new approach was developed to estimate indirect loss, using chamber methods together with the Penman-Monteith model. Indirect loss was only 0.9% of water supply, but this value probably was anomalously low due to a recurring leach-field malfunction. Resulting drainage beneath the leach-field was 80.4% of water supply. Guidelines are given to apply the same methodology at other sites and combine results with a survey of leach-fields in an area to obtain more realistic average values of ET losses.

Culture-based E. coli and enterococci have been used in empirical predictive models to characterize their responses to environmental conditions and to increase monitoring frequency and efficiency. This approach has been attempted with qPCR results only in few studies. During the summer of 2006, water samples were collected from two southern Lake Michigan beaches and the nearby river outfall (Burns Ditch) and were analyzed for enterococci by culture-based and non-culture-based (i.e., qPCR) methods, as well as culture-based E. coli. Culturable enterococci densities (log CFU/100ml) for the beaches were significantly correlated with enterococci qPCR cell equivalents (CE) (R=0.650, P<0.0001, N=32). Enterococci CE and CFU densities were highest in Burns Ditch relative to the beach sites; however, only CFUs were significantly higher (P<0.0001). Culturable enterococci densities at Burns Ditch and the beaches were significantly correlated (R=0.565, P<0.0001, N=32). Culturable E. coli and enterococci densities were significantly correlated (R=0.682, P<0.0001, N=32). Regression analyses suggested that enterococci CFU could be predicted by lake turbidity, Burns Ditch discharge, and wind direction (adjusted R super(2)=0.608); enterococci CE was best predicted by Burns Ditch discharge and log-transformed lake turbidityA-wave height (adjusted R super(2)=0.40). In summary, our results show that analytically, the qPCR method compares well to the non-culture-based method for measuring enterococci densities in beach water and that both these approaches can be predicted by hydrometeorological conditions. Selected predictors and model results highlight the differences between the environmental responses of the two method endpoints and the potentially high variance in qPCR results.

13447080 AB - Pollen analysis of two cores with discontinuous records from a peat bog near Girdwood, in south-central Alaska, provides the basis for reconstructing the first radiocarbon-dated outline of postglacial history of vegetation in the upper Turnagain Arm area of Cook Inlet. Pollen data from clayey silt underlying peat at one site indicate that the earliest known vegetation in the Girdwood area was shrub-herb tundra. Tundra vegetation developed by ~13 800 cal years BP, soon after local retreat of glacial ice from the maximum position of the Elmendorf glacial advance (~15 000 - 11 000 cal years BP). By ~10 900 cal years BP, the tundra vegetation became shrubbier as Betula nana, Salix, and Ericales increased, and scattered Alnus shrubs began to colonize Turnagain Arm. By ~9600 cal years BP, Alnus thickets with Polypodiaceae ferns became the dominant vegetation. By ~6600 cal years BP, birch trees (Betula neoalaskana, B. kenaica) from the Anchorage and Kenai lowlands began to spread eastward into eastern Turnagain Arm. Mountain hemlock (Tsuga mertensiana) began to colonize the Girdwood area by ~3400 cal years BP, followed soon after by Sitka spruce (Picea sitchensis), both Pacific coastal forest species that spread westward from Prince William Sound after a long migration from southeastern Alaska. For at least the past 2700 cal years, Pacific coastal forest composed mostly of Tsuga mertensiana, Picea sitchensis, and Alnus has been the dominant vegetation of eastern Turnagain Arm.Original Abstract: Une analyse de pollens de deux carottes dont les donnees sont discontinues, prelevees dans une tourbiere a proximite de Girdwood, dans le centre-sud de l'Alaska, fournit une base pour la reconstruction des premieres grandes lignes de l'historique post-glaciaire de la vegetation dans la partie superieure de la region du bras Turnagain du bras de mer Cook, tel que determine par datation au radiocarbone. A un site, les donnees sur le pollen provenant d'un silt argileux sous la tourbe indiquent que la premiere vegetation connue dans la region de Girdwood etait une toundra arbustive et herbacee. La vegetation de toundra s'est developpee vers ~13,800 annees calibrees avant le present (annees cal. BP), peu apres le retrait local de glace de la position maximale de l'avancee glaciaire Elmendorf (~15,000− 11,000 annees cal. BP). Vers ~10,900 annees cal. BP, la toundra est devenue plus arbustive alors que les quantites de Betula nana, de Salix et d'Ericales augmentaient et que des arbustes Alnus disperses commencaient a coloniser la peninsule Turnagain. Vers 9600 annees cal. BP des taillis Alnus avec des fougeres de Polypodiaceae constituaient la vegetation dominante. Vers 6600 annees cal. BP, des bouleaux (Betula neoalaskana, B. kenaica) des basses terres d'Anchorage et de Kenai commencaient a se repandre vers l'est dans la peninsule Turnagain orientale. La pruche subalpine (Tsuga mertensiana) a commence a coloniser la region de Girdwood vers 3400 annees cal. BP, suivi de pres par l'epinette de Sitka (Picea sitchensis), deux especes de la foret cotiere du Pacifique qui se sont etendues vers l'ouest du golfe du Prince William apres une longue migration du sud-est de l'Alaska. Pour les 2700 dernieres annees calibrees au moins, la foret cotiere du Pacifique etait composee principalement de Tsuga mertensiana, Picea sitchensis et de Alnus a constitue la vegetation dominante de bras Turnagain orientale.

For hydrodynamic modeling, we created a bathymetric layer of the Bonneville Reach from single-beam and multi-beam echo-sounder surveys, digital elevation models, and navigation surveys. We calibrated the hydrodynamic model at 100 and 300 kcfs with a user-defined roughness layer, a variable-sized mesh, and a U.S. Army Corps of Engineers backwater curve. We verified the 2D model with acoustic Doppler current profiler (ADCP) data at 14 transects and three flows. The 2D model was 88% accurate for water depths, and 77% accurate for velocities. We verified a pre-dam 2D model run at 126 kcfs using pre-dam aerial photos from September 1935. Hydraulic simulations indicated that mean water depths in the Bonneville Reach increased by 34% following dam construction, while mean velocities decreased by 58%. There are numerous activities that would benefit from data output from the 2D model, including biological sampling, bioenergetics, and spatially explicit habitat modeling.

We used radio telemetry to monitor the passage of adult Pacific lampreys at the Willamette Falls Project (a hydroelectric dam integrated into a natural falls) on the Willamette River near Portland, Oregon. In 2005 and 2006, fish were captured at the Project, implanted with a radio tag, and released downstream. We tagged 136 lampreys in 2005 and 107 in 2006. Over 90% of the fish returned to the Project in 7 - 9 h and most were detected from 2000 - 2300 h. In 2005, 43 fish (34%) passed the dam via the fishway, with peak passage in August. No fish passed over the falls, but 13% ascended at least partway up the falls. In 2006, 24 fish (23%) passed the Project using the fishway, with most prior to 9 June when the powerhouse was off. Although 19 lampreys ascended the falls, only two passed via this route. The time for fish to pass through the fishway ranged from 4 - 74 h, depending on route. Many fish stayed in the tailrace for hours to almost a year and eventually moved downstream. Our results indicate that passage of lampreys at the Project is lower than that for lampreys at dams on the Columbia River. Low passage success may result from low river flows, impediments in fishways, delayed tagging effects, changing environmental conditions, or performance or behavioral constraints.

We employ a simple model wherein lake-level decline exposes unvegetated littoral sediment to deflation, resulting in dune building. Dunes formed subsequent to lake-level decline prior to stabilization by vegetation and provide minimum ages for lake-level decline. Optical ages range from 10.3 to 7.7ka; 15 ages on dunes adjacent to the lowest Lake Minong shoreline suggest final water-level decline 9.1ka. The clustering of optical ages from vertically separated dunes on both sides of the Nadoway-Gros Cap Barrier around 8.8ka and a basal radiocarbon date behind the barrier (8120 plus or minus 40 14C yr BP [9.1 cal ka BP]) support the hypothesis that the barrier was breached and the final lake-level drop to the Houghton Low occurred coincident with (1) high meltwater flux into the Superior basin and (2) an abrupt, negative shift in oxygen isotope values in Lake Huron.

Although this assumption has been tested using marine and estuarine fish in controlled laboratory experiments, the relationships among temperature, ambient elemental concentration, and otolith chemical composition for freshwater species is not well documented. Here, juvenile yellow perch (Perca flavescens) were reared under different concentrations of four elements (Ba, Mg, Mn, and Sr) crossed with three temperatures (10 C, 15 C, and 20 C) to determine the interactive influence of ambient elemental concentrations and temperature on otolith chemical composition. Sr:Ca and Ba:Ca were significantly related to ambient elemental concentrations, but Mg:Ca and Mn:Ca were not. Although the relative influence of temperature was less than that of ambient elemental concentrations, Sr:Ca, Ba:Ca, and Mn:Ca were all influenced by either water temperature or the interaction between temperature and elemental concentration, but the direction of the temperature effect differed for each element. Patterns in our partition coefficients are consistent with the idea that uptake of strontium facilitates uptake of barium. Overall, yellow perch otolith element composition was influenced primarily by ambient Sr and Ba concentrations, but temperature could potentially confound the results of otolith microchemistry studies.Original Abstract: Les etudes microchimiques des otolithes presupposent l'existence d'une relation entre la concentration des elements en trace dans l'environnement et la composition chimique des otolithes. Bien que cette presupposition ait ete verifiee chez des poissons marins et estuariens dans des experiences controlees en laboratoire, la relation entre la temperature, les concentrations ambiantes d'elements et la composition chimique des otolithes chez les especes d'eau douce n'a pas ete bien etablie. Nous avons eleve ici de jeunes perchaudes (Perca flavescens) dans diverses concentrations de quatre elements (Ba, Mg, Mn et Sr) combinees a trois temperatures (10 C, 15 C et 20 C) afin de determiner l'influence interactive des concentrations ambiantes d'elements et de la temperature sur la composition chimique des otolithes. Sr:Ca et Ba:Ca sont en relation significative avec les concentrations ambiantes d'elements, mais Mg:Ca et Mn:Ca ne le sont pas. Bien que l'influence relative de la temperature soit moindre que celle des concentrations ambiantes d'elements, Sr:Ca, Ba:Ca et Mn:Ca sont tous influences ou bien par la temperature de l'eau ou alors par l'interaction entre la temperature et la concentration d'elements, mais le sens de l'effet de la temperature differe pour chacun des elements. Les patrons dans les coefficients de partition obtenus sont compatibles avec la notion que l'incorporation de strontium facilite l'incorporation de barium. De facon globale, la composition des elements dans les otolithes de perchaudes est influencee principalement par les concentrations ambiantes de Sr et Ba, mais la temperature pourrait potentiellement fausser les resultats d'etudes sur la microchimie des otolithes.

Inference based on spatial replication strictly requires that replicates be selected randomly and with replacement, but the importance of these design requirements is not well understood. This paper focuses on an increasingly popular sampling design based on spatial replicates that are not selected randomly and that are expected to exhibit Markovian dependence. We develop two new occupancy models for data collected under this sort of design, one based on an underlying Markov model for spatial dependence and the other based on a trap response model with Markovian detections. We then simulated data under the model for Markovian spatial dependence and fit the data to standard occupancy models and to the two new models. Bias of occupancy estimates was substantial for the standard models, smaller for the new trap response model, and negligible for the new spatial process model. We also fit these models to data from a large-scale tiger occupancy survey recently conducted in Karnataka State, southwestern India. In addition to providing evidence of a positive relationship between tiger occupancy and habitat, model selection statistics and estimates strongly supported the use of the model with Markovian spatial dependence. This new model provides another tool for the decomposition of the detection process, which is sometimes needed for proper estimation and which may also permit interesting biological inferences. In addition to designs employing spatial replication, we note the likely existence of temporal Markovian dependence in many designs using temporal replication. The models developed here will be useful either directly, or with minor extensions, for these designs as well. We believe that these new models represent important additions to the suite of modeling tools now available for occupancy estimation in conservation monitoring. More generally, this work represents a contribution to the topic of cluster sampling for situations in which there is a need for specific modeling (e.g., reflecting dependence) for the distribution of the variable(s) of interest among subunits.

The source of the estimation problems is the particular parameterization used to specify species co-occurrence probability. We develop a new parameterization for estimating patterns of co-occurrence of interacting species that allows the effects of covariates to be specified quite naturally without estimation problems. In our model, the occurrence of one species is assumed to depend on the occurrence of another, but the occurrence of the second species is not assumed to depend on the presence of the first species. This pattern of co-occurrence, wherein one species is dominant and the other is subordinate, can be produced by several types of ecological interactions (predator-prey, parasitism, and so on). A simulation study demonstrated that estimates of species occurrence probabilities were unbiased in samples of 50-100 locations and three surveys per location, provided species are easily detected (probability of detection . 0.5). Higher sample sizes (>200 locations) are needed to achieve unbiasedness when species are more difficult to detect. An analysis of data from treefrog surveys in southern Florida indicated that the occurrence of Cuban treefrogs, an invasive predator species, was highest near the point of its introduction and declined with distance from that location. Sites occupied by Cuban treefrogs were 9.0 times less likely to contain green treefrogs and 15.7 times less likely to contain squirrel treefrogs compared to sites without Cuban treefrogs. The detection probabilities of native treefrog species did not depend on the presence of Cuban treefrogs, suggesting that the native treefrog species are naive to the introduced species.

Invertebrate assemblages in metropolitan areas where forests or shrublands were being converted to urban land were strongly related to urban intensity. In metropolitan areas where agriculture and grazing lands were being converted to urban land, invertebrate assemblages showed much weaker or nonsignificant relations with urban intensity because sites with low urban intensity were already degraded by agriculture. Ordination scores, the number of EPT taxa, and the mean pollution-tolerance value of organisms at a site were the best indicators of changes in assemblage condition. Diversity indices, functional groups, behavior, and dominance metrics were not good indicators of urbanization. Richness metrics were better indicators of urban effects than were abundance metrics, and qualitative samples collected from multiple habitats gave similar results to those of single habitat quantitative samples (riffles or woody snags) in all metropolitan areas. Changes in urban intensity were strongly correlated with a set of landscape variables that was consistent across all metropolitan areas. In contrast, the instream environmental variables that were strongly correlated with urbanization and invertebrate responses varied among metropolitan areas. The natural environmental setting determined the biological, chemical, and physical instream conditions upon which urbanization acts and dictated the differences in responses to urbanization among metropolitan areas. Threshold analysis showed little evidence for an initial period of resistance to urbanization. Instead, assemblages were degraded at very low levels of urbanization, and response rates were either similar across the gradient or higher at low levels of urbanization. Levels of impervious cover that have been suggested as protective of streams (5-10%) were associated with significant assemblage degradation and were not protective.

The strategy of selective grouting was investigated in Antelope Valley, California, where groundwater supplies most of the water demand. Naturally occurring arsenic typically exceeds concentrations of 10 kg/L in the water produced from these long-screened wells. The vertical distributions of arsenic concentrations in intervals of the aquifer contributing water to selected supply wells were characterized with depth-dependent water-quality sampling and flow logs. Arsenic primarily entered the lower half of the wells where lacustrine clay deposits and a deeper aquifer occurred. Five wells were modified by grouting from below the top of the lacustrine clay deposits to the bottom of the well, which reduced produced arsenic concentrations to less than 2 kg/L in four of the five wells. Long-term viability of well modification and reduction of specific capacity was assessed for well 4-54 with AnalyzeHOLE, which creates and uses axisymmetric, radial MODFLOW models. Two radial models were calibrated to observed borehole flows, drawdowns, and transmissivity by estimating hydraulic-conductivity values in the aquifer system and gravel packs of the original and modified wells. Lithology also constrained hydraulic-conductivity estimates as regularization observations. Well encrustations caused as much as 2 kg/L increase in simulated arsenic concentration by reducing the contribution of flow from the aquifer system above the lacustrine clay deposits. Simulated arsenic concentrations in the modified well remained less than 3 kg/L over a 20-year period.

Given the importance of groundwater as a source of drinking water in many areas of the world, this study examines the potential sources and geochemical processes that control the distribution of V in groundwater on a regional scale. Potential sources of V to groundwater include dissolution of V rich rocks, and waste streams from industrial processes. Geochemical processes such as adsorption/desorption, precipitation/dissolution, and chemical transformations control V concentrations in groundwater. Based on thermodynamic data and laboratory studies, V concentrations are expected to be highest in samples collected from oxic and alkaline groundwater. However, the extent to which thermodynamic data and laboratory results apply to the actual distribution of V in groundwater is not well understood. More than 8400 groundwater samples collected in California were used in this study. Of these samples, high (.50 kg/L) and moderate (25 to 49 kg/L) V concentrations were most frequently detected in regions where both source rock and favorable geochemical conditions occurred. The distribution of V concentrations in groundwater samples suggests that significant sources of V are mafic and andesitic rock. Anthropogenic activities do not appear to be a significant contributor of V to groundwater in this study. High V concentrations in groundwater samples analyzed in this study were almost always associated with oxic and alkaline groundwater conditions, which is consistent with predictions based on thermodynamic data.

The adult return rate of Dennys smolts is comparatively low, and disparity in smolt quality between stocks resulting from genetic or broodstock rearing effects is plausible. Smolt behavior and physiology were assessed during sequential 14-d trials conducted in seminatural annular tanks with circular flow. 'Migratory urge' (downstream movement) was monitored remotely using passive integrated transponder tags, and gill Na super(+),K super(+)-ATPase activity was measured at the beginning and end of the trials to provide an index of smolt development. The migratory urge of both stocks was low in early April, increased 20-fold through late May, and declined by the end of June. The frequency and seasonal distribution of downstream movement were independent of stock. In March and April, initial gill Na super(+),K super(+)-ATPase activities of Penobscot River smolts were lower than those of Dennys River smolts. For these trials, however, Penobscot River smolts increased enzyme activity after exposure to the tank, whereas Dennys River smolts did not, resulting in similar activities between stocks at the end of all trials. There was no clear relationship between migratory urge and gill Na super(+),K super(+)-ATPase activity. Gill Na super(+),K super(+)-ATPase activity of both stocks increased in advance of migratory urge and then declined while migratory urge was increasing. Maximum movement was observed from 2 h after sunset through 1 h after sunrise but varied seasonally. Dennys River smolts were slightly more nocturnal than Penobscot River smolts. These data suggest that Dennys and Penobscot River stocks are not markedly different in either physiological or behavioral expression of smolting.

The bacterial community was dominated ( 85% of 16S rRNA gene clones) by sequences from the photosynthetic Ectothiorhodospira genus. Scraped biofilm materials incubated under anoxic conditions rapidly oxidized As(III) to As(V) in the light via anoxygenic photosynthesis but could also readily reduce As(V) to As(III) in the dark at comparable rates. Back-labeling experiments with 73As(V) demonstrated that reduction to 73As(III) also occurred in the light, thereby illustrating the cooccurrence of these two anaerobic processes as an example of closely coupled arsenotrophy. Oxic biofilms also oxidized As(III) to As(V). Biofilms incubated with [14C]acetate oxidized the radiolabel to 14CO2 in the light but not the dark, indicating a capacity for photoheterotrophy but not chemoheterotrophy. Anoxic, dark-incubated samples demonstrated As(V) reduction linked to additions of hydrogen or sulfide but not acetate. Chemoautotrophy linked to As(V) as measured by dark fixation of [14C]bicarbonate into cell material was stimulated by either H2 or HS-. Functional genes for the arsenate respiratory reductase (arrA) and arsenic resistance (arsB) were detected in sequenced amplicons of extracted DNA, with about half of the arrA sequences closely related (98% translated amino acid identity) to those from the family Ectothiorhodospiraceae. Surprisingly, no authentic PCR products for arsenite oxidase (aoxB) were obtained, despite observing aerobic arsenite oxidation activity. Collectively, these results demonstrate close linkages of these arsenic redox processes occurring within these biofilms.

Its incidence in Yellowstone cutthroat trout Oncorhynchus clarkii bouvieri within the highly protected environment of Yellowstone Lake, Yellowstone National Park, is a prime example. Given the local abundances of piscivorous birds, we sought to clarify their potential role in the dissemination of M. cerebralis. Six individuals from each of three bird species (American white pelican Pelecanus erythrorhynchos, double-crested cormorant Phalacrocorax auritus, and great blue heron Ardea herodias) were fed known-infected or uninfected rainbow trout O. mykiss. Fecal material produced during 10-d periods before and after feeding was collected to determine whether M. cerebralis could be detected and, if so, whether it remained viable after passage through the gastrointestinal tract of these birds. For all (100%) of the nine birds fed known-infected fish, fecal samples collected during days 1-4 after feeding tested positive for M. cerebralis by polymerase chain reaction. In addition, tubificid worms Tubifex tubifex that were fed fecal material from known-infected great blue herons produced triactinomyxons in laboratory cultures, confirming the persistent viability of the parasite. No triactinomyxons were produced from T. tubifex fed fecal material from known-infected American white pelicans or double-crested cormorants, indicating a potential loss of parasite viability in these species. Great blue herons have the ability to concentrate and release viable myxospores into shallow-water habitats that are highly suitable for T. tubifex, thereby supporting a positive feedback loop in which the proliferation of M. cerebralis is enhanced. The presence of avian piscivores as an important component of aquatic ecosystems should continue to be supported. However, given the distances traveled by great blue herons between rookeries and foraging areas in just days, any practices that unnaturally attract them may heighten the probability of M. cerebralis dispersal and proliferation within the Greater Yellowstone Ecosystem.

The units include a mosaic of freshwater and shallow marine deposits that accumulated on the Florida platform during high sea-level stands. The units are separated by regional-scale subaerial-exposure surfaces that formed during glacioeustatic lowstands. Analyses of cores recovered at Grossman Ridge Rock Reef and Joe Ree Rock Reef in the Florida Everglades reveal additional subaerial-exposure surfaces that are used to delineate subdivisions within units Q1 (Q1a-Q1b), Q2 (Q2a-Q2d), and Q4 (Q4a-Q4b). Units Q1-Q5 preserve evidence of at least 10 separate sea-level highstands, rather than 5 as indicated by previous studies.

Movement rates between regions were substantial enough to result in continual mixing of wintering birds. Thus, we were unable to identify distinct subpopulations based on exclusive use of specific wintering areas. These birds should therefore be monitored, and their harvest managed, as if they were one population.

Analyses in recent years have identified inconsistencies in results between surveys, and a need exists to analyze the surveys using modern methods and examine possible causes of differences in survey results. Call-Count Survey observers collect separate information on number of doves heard and number of doves seen during counting, whereas BBS observers record one index containing all doves observed. We used hierarchical log-linear models to estimate trend and annual indices of abundance for 1966-2007 from BBS data, CCS-heard data, and CCS-seen data. Trend estimates from analyses provided inconsistent results for several states and for eastern and central dove-management units. We examined differential effects of change in land use and noise-related disturbance on the CCS indices. Changes in noise-related disturbance along CCS routes had a larger influence on the heard index than on the seen index, but association analyses among states of changes in temperature and of amounts of developed land suggest that CCS indices are differentially influenced by changes in these environmental features. Our hierarchical model should be used to estimate population change from dove surveys, because it provides an efficient framework for estimating population trends from dove indices while controlling for environmental features that differentially influence the indices.

Phosphatidylcholines, which are an important component of some fungal and bacterial cell membranes, were completely recovered when a larger ratio of 20:1 v/w methanol (mL) to silica (g) was used. Separation of phospholipids from a soil sample showed that a methanol:silica ratio of 20:1 recovered substantially greater amounts of phospholipids and resulted in a different phospholipid fatty acid (PLFA) structural profile than a 10:1 ratio. This study also confirmed that methanol preconditioning of the manufactured SPE columns studied is necessary for quantitative recovery of phospholipids.

We use data from a large scale Web survey hosted on National Geographic's Web site in 2001-2002 to investigate this premise. We examine whether reading three classic environmental books ( Walden, A Sand County Almanac, and Silent Spring) is associated with the likelihood of engaging in ERB. Conceptualizing this activity as a formative experience and a source of environmental knowledge, we hypothesized that reading such literature would be a stronger predictor of ERB than sociodemographic characteristics (i.e., gender, education, and political orientation), general environmental attitudes (as measured by the New Ecological Paradigm), and concern about specific environmental risks. The results indicated that while reading environmental literature was a stronger predictor of ERB than background characteristics and the NEP, environmental concern was an even stronger predictor. We offer reasons for these findings and make suggestions for environmental education and future research. Reprinted by permission of Sage Publications, Inc.

An information- theoretic approach was used on data from 197 salvaged bald eagle (Haliaeetus leucocephalus) eggs (159 clutches) that failed to hatch in Michigan and Ohio, USA (1986-2000). Contaminant levels declined over time while eggshell thickness increased, and by 2000 was at pre-1946 levels. The number of occupied territories and productivity increased during 1981 to 2004. For both the entire dataset and a subset of nests along the Great Lakes shoreline, polychlorinated biphenyls ( capital sigma PCBs, fresh wet wt) were generally included in the most parsimonious models (lowest-Akaike's information criterion [AICs]) describing productivity, with significant declines in productivity observed above 26 [mu]g/g capital sigma PCBs (fresh wet wt). Of 73 eggs with a visible embryo, eight (11%) were abnormal, including three with skewed bills, but they were not associated with known teratogens, including capital sigma PCBs. Eggs with visible embryos had greater concentrations of all measured contaminants than eggs without visible embryos; the most parsimonious models describing the presence of visible embryos incorporated dieldrin equivalents and dichlorodiphenyldichloroethylene (DDE). There were significant negative correlations between eggshell thickness and all contaminants, with capital sigma PCBs included in the most parsimonious models. There were, however, no relationships between productivity and eggshell thickness or Ratcliffe's index. The capital sigma PCBs and DDE were negatively associated with nest success of bald eagles in the Great Lakes watersheds, but the mechanism does not appear to be via shell quality effects, at least at current contaminant levels, while it is not clear what other mechanisms were involved.

Morphological changes on the Mississippi-Alabama barrier-island chain produced by 12 Category 3 and stronger hurricanes since 1852 were analyzed to investigate whether barrier-island responses to extreme storms are controlled primarily by local geomorphic conditions or primarily by storm characteristics. Results of those analyses demonstrate that (1) antecedent topography and geomorphic conditions (island width, land elevations, nearshore bathymetry, subaqueous-boundary conditions) tend to exert greater control on local barrier-island impacts than storm parameters (path, intensity, wind speeds, water levels, shelf duration), and (2) types and alongshore patterns of storm overwash and island breaching are commonly repeated for the same island segments. Even when impact patterns are identical, magnitudes of sequential impacts, such as the inland distance of sediment transport, are unequal and are controlled by storm parameters (water levels, wind speeds) that influence wave heights, overwash-flow depths, and current velocities.

Learning how much sediment waterfowl can consume in their diet and still maintain their health would be helpful in assessing potential threats from contaminants in sediment. In a controlled laboratory study the maximum tolerated percentage of sediment in the diet of mallards (Anas platyrhynchos) was measured. When fed a well-balanced commercial avian diet, 50, 60, or 70% sediment in the diet on a dry-weight basis did not cause weight loss over a two-week period. Ducks fed this same commercial diet, but containing 80 or 90% sediment, lost 8.6 and 15.6% of their body weight, respectively, in the first week on those diets. After factoring in the ability of the mallards to sieve out some of the sediment from their diet before swallowing it, we concluded that the mallards could maintain their health even when approximately half of what they swallowed, on a dry-weight basis, was sediment.

Understanding how past and present water management has affected rivers is an important part of developing such tools. In this paper, we evaluate how existing hydrologic infrastructure and management affect streamflow characteristics of rivers in the Central Valley, California and discuss those characteristics in the context of habitat requirements of native and alien fishes. We evaluated the effects of water management by comparing observed discharges with estimated discharges assuming no water management ('full natural runoff'). Rivers in the Sacramento River drainage were characterized by reduced winter-spring discharges and augmented discharges in other months. Rivers in the San Joaquin River drainage were characterized by reduced discharges in all months but particularly in winter and spring. Two largely unaltered streams had hydrographs similar to those based on full natural runoff of the regulated rivers. The reduced discharges in the San Joaquin River drainage streams are favourable for spawning of many alien species, which is consistent with observed patterns of fish distribution and abundance in the Central Valley. However, other factors, such as water temperature, are also important to the relative success of native and alien resident fishes. As water management changes in response to climate change and societal demands, interdisciplinary programs of research and monitoring will be essential for anticipating effects on fishes and to avoid unanticipated ecological outcomes.

To test the sensitivity of calculated habitat outcomes to limitations of such a model and of typical field data, bathymetry, depth and velocity data were collected for three discharges in the vicinity of two large boulders in the South Platte River (Colorado) and used in the River2D model. Simulated depth and velocity were compared with observed values at 204 locations and the differences in habitat numbers produced by observed and simulated conditions were calculated. The bulk of the differences between simulated and observed depth and velocity values were found to lie within the likely error of measurement. However, the effect of flow simulation outliers on potential habitat outcomes must be considered when using 2D models for habitat simulation. Furthermore, the shape of the habitat suitability relation can influence the effects of simulation errors. Habitat relations with steep slopes in the velocity ranges found in similar study areas are expected to be sensitive to the magnitude of error found here. Comparison of habitat values derived from simulated and observed depth and velocity revealed a small tendency to under-predict habitat values. Published in 2009 by John Wiley & Sons, Ltd.

Low-flow discharge and major solute chemistry AN - 754869838; 13215031 AB - The Gibbon River in Yellowstone National Park (YNP) is an important natural resource and habitat for fisheries and wildlife. However, the Gibbon River differs from most other mountain rivers because its chemistry is affected by several geothermal sources including Norris Geyser Basin, Chocolate Pots, Gibbon Geyser Basin, Beryl Spring, and Terrace Spring. Norris Geyser Basin is one of the most dynamic geothermal areas in YNP, and the water discharging from Norris is much more acidic (pH 3) than other geothermal basins in the upper-Madison drainage (Gibbon and Firehole Rivers). Water samples and discharge data were obtained from the Gibbon River and its major tributaries near Norris Geyser Basin under the low-flow conditions of September 2006. Surface inflows from Norris Geyser Basin were sampled to identify point sources and to quantify solute loading to the Gibbon River. The source and fate of the major solutes (Ca, Mg, Na, K, SiO sub(2), Cl, F, HCO sub(3), SO sub(4), NO sub(3), and NH sub(4)) in the Gibbon River were determined in this study and these results may provide an important link in understanding the health of the ecosystem and the behavior of many trace solutes. Norris Geyser Basin is the primary source of Na, K, Cl, SO sub(4), and N loads (35-58%) in the Gibbon River. The largest source of HCO sub(3) and F is in the lower Gibbon River reach. Most of the Ca and Mg originate in the Gibbon River upstream from Norris Geyser Basin. All the major solutes behave conservatively except for NH sub(4), which decreased substantially downstream from Gibbon Geyser Basin, and SiO sub(2), small amounts of which precipitated on mixing of thermal drainage with the river. As much as 9-14% of the river discharge at the gage is from thermal flows during this period.

On 31 July 2006, unprecedented debris flows occurred in the Santa Catalina Mountains of southeastern Arizona following extreme multiday precipitation (recurrence interval >1000years for 4-day precipitation). Most mobilized sediment contributing to debris flows was derived from shallow-seated failures of colluvium on steep slopes. A total of 435 slope failures in the southern Santa Catalina Mountains released 1.34millionMg of sediment into the channels of 10 drainage basins. Five drainages produced debris flows that moved to the apices of alluvial fans on the southern edge of the mountain front, damaging infrastructure and aggrading channels to reduce future flood conveyance. Using the statistically calibrated, empirical debris-flow model LAHARZ and modified model coefficients developed to better match conditions in southeastern Arizona, we predicted the approximate area of deposition and travel distance in comparison to observed depositional areas and travel distance for seven debris flows. Two of the modeled debris flows represented single slope failures that terminated downslope with no additive influence of other debris flows or streamflow flooding. Five of the simulated debris flows represented the aggregation of multiple slope failures and streamflow flooding into multiple debris-flow pulses. Because LAHARZ is a debris-flow hazard-zone delineation tool, the complexity of alternating transport and deposition zones in channels with abrupt expansions and contractions reduces the applicability of the model in some drainage basins.

Attempting to reduce fuel loads and expedite forest regeneration in these areas, the USDA Forest Service often disrupts this cycle by the logging of fire-killed trees, replanting of conifers and killing of shrubs. We measured the effects of these treatments on live and dead fuel loads and alien species and modeled potential fire behavior and fire effects on regenerating forests. Sampling occurred in untreated, logged and herbicide-treated stands throughout the Sierra Nevada in four large fire areas 4-21 years after stand-replacing fires. Logging fire-killed trees significantly increased total available dead fuel loads in the short term but did not affect shrub cover, grass and forb cover, alien species cover or alien species richness. Despite the greater available dead fuel loads, fire behavior was not modeled to be different between logged and untreated stands, due to abundant shrub fuels in both logged and untreated stands. In contrast, the herbicide treatment directed at shrubs resulted in extremely low shrub cover, significantly greater alien species richness and significantly greater alien grass and forb cover. Grass and forb cover was strongly correlated with solar radiation on the ground, which may be the primary reason that grass and forb cover was higher in herbicide treated stands with low shrub and tree cover. Repeat burning exacerbated the alien grass problem in some stands. Although modeled surface fire flame lengths and rates of spread were found to be greater in stands dominated by shrubs, compared to low shrub cover conifer plantations, surface fire would still be intense enough to kill most trees, given their small size and low crown heights in the first two decades after planting.

LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2010-08-02 N1 - Last updated - 2010-09-25 ER - TY - JOUR T1 - Morphological plasticity reduces the effect of poor developmental conditions on fledging age in mourning doves AN - 745699980; 13003536 AB - Developmental plasticity can be integral in adapting organisms to the environment experienced during growth. Adaptive plastic responses may be especially important in prioritizing development in response to stress during ontogeny. To evaluate this, I examined how developmental conditions for mourning doves related to early growth and how this affected fledging age, an important life-history transition for birds. The life history of mourning doves is consistent with strong selective pressure to minimize fledging age. Therefore, I predicted that in the face of nutritional stress associated with experimental brood-size increases, young would prioritize growth to structures that promote early fledging to reduce the effect of slowed overall growth on fledging age. Increasing brood size slowed overall structural growth of nestlings and affected the relative allocation of growth among different body parts. Total wing area was the best predictor of fledging age and individuals from larger broods had larger wings relative to overall body size. Although nestlings from larger broods fledged at later ages owing to slower overall growth, prioritization of wing growth reduced this effect by an estimated 1.6 days relative to the delay if plasticity among body parts had not occurred. This was an 11 per cent reduction in the predicted developmental time it took to reach this important life-history transition. Results demonstrate that preferential allocation to wing growth can affect the timing of this life-history transition and that morphological plasticity during development can have adaptive near-term effects during avian development.

14137011 AB - Utility of early-season mosquito surveillance to predict West Nile virus activity in late summer was assessed in Suffolk County, NY Dry ice-baited CDC miniature light traps paired with gravid traps were set weekly. Maximum-likelihood estimates of WNV positivity, minimum infection rates, and % positive pools were generally well correlated. However, positivity in gravid traps was not correlated with positivity in CDC light traps. The best early-season predictors of WNV activity in late summer (estimated using maximum-likelihood estimates of Culex positivity in August and September) were early date of first positive pool, low numbers of mosquitoes in July, and low numbers of mosquito species in July. These results suggest that early-season entomological samples can be used to predict WNV activity later in the summer, when most human cases are acquired. Additional research is needed to establish which surveillance variables are most predictive and to characterize the reliability of the predictions.

Two new Mylodontinae (Xenarthra, Tardigrada, Mylodontoidea) from the Bolivian Altiplano are described. One of them, Pleurolestodon dalenzae n. sp., was discovered a few meters below a volcanic tuff, Toba 76, that may be used as a reference stratigraphic level and is dated at 5.4 Ma; it could be Huayquerian (late Miocene) or at the Huayquerian-Montehermosan boundary in age. The other taxon, Simomylodon uccasamamensis n. gen., n. sp., was recovered from many localities of a horizon bounded below by Toba 76 and above by another volcanic level, the 2.8 Ma Ayo Ayo tuff; its age is Montehermosan Chapadmalalan (early and middle Pliocene). Analysis of these taxa indicates that they are Mylodontidae more closely related to Glossotherium, Glossotheridium, Kiyumylodon and Paramylodon than to Lestodon or Thinobadistes.

Behavioral inspection of predator chemical cues implies that sensory modes other than visual detection may be important for assessing predation risk in shoaling fishes. To assess the potential for inspection behavior by fathead minnow (Pimephales promelas; FHM), we quantified the responses of FHM to chemical cues of a natural predator, northern pike, and chemical cues of conspecifics. The presence of northern pike odor elicited inspection-like behavior among FHM. In control treatments, FHM remained within vegetated cover, and no differences were observed in the number of individuals in open water areas. When northern pike odor was added, significantly more FHM were observed in the open water habitat, although FHM activity was similar to that of controls. This suggests that FHM respond to northern pike chemical cues via directional movement into the open water habitats. These results indicate that FHM acquire information about potential predation risk in the absence of visual cues and engage in seemingly high risk investigating activity.

Eggs from three more females in 2009 were manually spawned, fertilized, and incubated in the laboratory until they hatched on day 11. The mean thiamine concentration in these eggs was 2.7 c 0.3 nmol/g. To detect possible thiamine deficiency, on day 12 larvae from each female were divided into two groups and immersed in either static culture water alone or the same water with 5,000 mg/L thiamine for 6 hrs, after which they were held as six individual groups and fed twice daily starting on day 23 until all control larvae had died on day 29. Thiamine treatment significantly (P<0.001) increased survival of unfed larvae between days 15 and 18 and fed larvae between days 24 and 29 (P0.05). While most smelt captured in 2008 and 2009 contained adequate egg thiamine, some produced eggs low in thiamine, resulting in increased mortality of their fry, which was reduced by treatment with thiamine.

To examine the association between D. geminata and the invertebrate community in Rapid Creek, macroinvertebrates were quantified using three gear types in the fall of 2006. D. geminata was present at two of four sites sampled (range = 5.53 to 809.68 g m super(-2) dry mass). At each site, invertebrates were collected using dip nets, Surber samplers, and drift nets. The combined percentage of Ephemeroptera, Plecoptera, and Trichoptera in areas with D. geminata was lower (41%) than in areas without D. geminata (76%). Diptera abundance was higher at sites with D. geminata than in sites where D. geminata was absent.

However, it is often difficult to measure early deposition rates, because the bottom surface is usually obscured under turbid, tidally-influenced waters. To accurately measure early sediment deposition in marshes, we developed an echosounder system consisting of a specialized acoustic profiler, differential global positioning system unit, and laptop computer mounted on a shallow-draft boat. We conducted a bathymetry survey at the Tubbs Setback tidal restoration site on San Pablo Bay, California, along north-south transects at 25-m intervals. Horizontal position was recorded within 1m each second and water depth to 1cm every 0.05s. Bottom elevations were adjusted for tidal height with surveyed tide gages. We created detailed bathymetric maps (grid cell size: 12.5m12.5m) by interpolation with inverse distance weighting. During the third year after restoration, sediment accretion averaged 57.1c1.1cm and the estimated sediment gain was 132,900m super(3). The mean difference between the elevations from the bathymetry system and the 9 sediment pins was 2.0c1.0cm. The mean difference of the intersection points of east-west and north-south survey transects was 2.1c0.2cm, which provided a measure of repeatability with changing water levels. Our echosounder system provided accurate and repeatable measurements of sediment accretion of a recently restored tidal wetland, and this system proved to be a viable tool for determining sediment deposition in marshes and assessing early restoration progress.

In these fish, experimental immersion challenges with U isolates cause extremely high mortality and M isolates cause low or no mortality. When survivors of M virus immersion challenges were exposed to a secondary challenge with virulent U type virus they experienced high mortality, indicating that the primary M challenge did not elicit protective immunity. Delivery of a moderate dose (2 10 super(4) plaque-forming units [PFU]/fish) of virus by intraperitoneal injection challenge did not overcome RFL sockeye salmon resistance to M type IHNV. Injection challenge with a high dose (5 10 super(6) PFU/fish) of M type virus caused 10% mortality, and in this case survivors did develop protective immunity against a secondary U type virus challenge. Thus, although it is possible for M type IHNV to elicit cross-protective immunity in this disease model, it does not develop after immersion challenge despite entry, transient replication of M virus to low levels, stimulation of innate immune genes, and development of neutralizing antibodies in some fish.

To evaluate progress toward lake trout rehabilitation in the Northern Refuge, we conducted annual (1991-2008) gill-net surveys in the fall to assess the adult population and beam trawl surveys in the spring to assess naturally reproduced age-0 lake trout. Our criteria for evaluating progress included the density of 'wild' age-0 fish within the Northern Refuge, the proportion of wild fish within the adult population, density of spawners, adult survival, growth, and wounding rate by sea lampreys Petromyzon marinus. No wild age-0 lake trout were caught in the Northern Refuge during 1991-2008. Overall, wild lake trout did not recruit to the adult population to any detectable degree. The mean density of spawning lake trout decreased from 45 fish.305 m of gill net super(-1).d super(ȡ 2; 1) during 1991-1999 to only 4 fish.305 m super(-1).d super(- 1) during 2000-2008. Although the sea lamprey wounding rate more than doubled between these two time periods, catch curve analysis revealed that mortality of adult lake trout actually decreased between the two periods. Therefore, the 90% decrease in abundance of spawning lake trout between the two periods could not be attributed to increased sea lamprey predation but instead was probably due in part to the reduced lake trout stocking rate during 1995-2005. The paucity of natural reproduction in the Northern Refuge during 1991-2008 most likely resulted from alewife Alosa pseudoharengus interference with lake trout reproduction and from the relatively low lake trout spawner density during 2000-2008. Our results suggest that the annual stocking rate of lake trout yearlings should be increased to at least 250,000 fish/reef to achieve greater densities of spawners.

Six adult Roseate Terns (Sterna dougallii) that had bred at colony sites in Buzzards Bay, Massachusetts, USA from 2004-2006 switched regions and moved 200-400 km to two colony sites in Maine between 2005 and 2007. Two of the emigrants presumably had nested for at least eight years in Massachusetts before moving to Maine, demonstrating that even long-time philopatric residents of one region may switch to another region.

However, few life history data are available for the species in North America. In 2001-2004, information was collected on nesting habitat and reproductive parameters (i.e. components of productivity) from a population of Black Scoters nesting on the Yukon-Kuskokwim Delta, Alaska. A total of 157 nests were found over four years. Primarily, nests were among dense vegetation in shrub edge habitat, predominantly dwarf birch (Betula glandulosa) and Alaska spiraea (Spiraea beauverdiana), an average of 58 m from water. Females initiated nests from 11 June and 17 July across years. Clutch size averaged 7.5 eggs and did not vary annually. Nest success was highly variable among years and ranged from 0.01 to 0.37. Duckling survival to 30 days old varied among years, and ranged from 0.09 - 0.35. Nest success was poor in three of four years, likely due to predation by Red Fox (Vulpes vulpes). Black Scoters appear to have low but variable productivity, consistent with life-history patterns of other sea duck species. Information gained will direct future demographic research on Black Scoters, and highlights knowledge gaps impeding management strategies needed for population recovery.

Birds were radiotagged just before or early in their flightless period on four wetlands that differed in size on Klamath Basin (KB) National Wildlife Refuge complex. Flightless survival varied among years but was higher on two larger than two smaller wetlands; 30-day survival ranged from 11% (SE = 6.5%) on a small wetland in 2006 to 93% (SE = 6.5%) on a large wetland in 2001, and averaged 76.8% (SE = 6.1%). Most flightless mortality was from avian botulism (64%) and predation (26%). Of the 81 radiotagged Mallards that did not die in KB, 80% moved to the Central Valley of California (CVCA) before 31 January, 16% wintered in unknown areas, and 4% remained in KB through 31 January. Mallards departed KB 21 August-13 January (average: 11 Nov 2001, 25 Oct 2002, 19 Nov 2006). Post-molt survival during August-March in KB (20.7%, SE = 6.3%) was lower than in CVCA during this (62.9%, SE = 10.1%) and an earlier study. Survival in KB was consistently high only for females that molted in large permanent marshes, and although the impact of poor survival of molting females on Mallard population dynamics is unknown, KB water management plans should be developed that maintain these habitats.

We examined the diet of double-crested cormorants (Phalacrocorax auritas) prior to, and immediately after, round goby population expansion at two colonies, Pigeon and Snake Islands, in eastern Lake Ontario from 1999 to 2007. Cormorant diet was determined from the examination of 10,167 pellets collected over the nine-year period. By the second year round gobies were found in the diet (2002 at Snake Island and 2003 at Pigeon Island) they were the main species consumed by cormorants at each colony. The dominance of round goby in cormorant diets had a significant effect on both daily fish consumption and seasonal trends in fish consumption compared to the pre-goby years. Seasonal differences that were observed during the pre-goby years were lost once gobies became the main diet component of cormorants. The rapid switch to a benthic prey such as round goby, from a largely limnetic fish diet demonstrates the adaptive foraging ability of cormorants. Round goby may act as a buffer for yellow perch and smallmouth bass, two sport fish impacted by cormorant predation in eastern Lake Ontario.

Slimy sculpins were collected from dreissenid-infested bottoms off seven Lake Michigan ports at depths of 27-73 m in fall 2003 to study their lake-wide diets. Relatively large dreissenid biomass occurred at depths of 37- and 46-m. Quagga mussels (Dreissena bugnesis) composed at least 50% of dreissenid biomass at Manistique, Saugatuck, and Sturgeon Bay. Mysis accounted for 82% of the sculpin diet by dry weight at eastern Lake Michigan while Diporeia composed 54-69% of the diet at western Lake Michigan and dominated the diets of slimy sculpins at all sites deeper than 46 m. In northern Lake Michigan, this diet study in new sites showed that slimy sculpin consumed more prey with low energy contents, especially chironomids, than Mysis and Diporeia in shallow sites (depth <55 m). We recommend diet studies on sedentary benthic fishes to be conducted along perimeters of the Great Lakes to observe changes in their diets that may be impacted by changing benthic macroinvertebrate communities.

The Moroccan turtle, Mauremys leprosa, occupies an extremely wide variety of ecoregions and habitats, including coastal rivers, mountain streams, oases, and intermittent rivers in the northern fringe of the Sahara Desert. To assess geographic variation in SSD, we collected specimens along an environmental gradient in central Morocco, including Oued (River) Ksob on the Atlantic coast, Oued Zat in the High Atlas Mountain foothills, and Oued Draa in the Sahara Desert. Only turtles with conspicuous secondary sexual characteristics were included in our analysis. We calculated a sexual dimorphism index (SDI) using the mean size of the larger sex divided by the mean size of the smaller sex and subtracted one from that ratio. The direction of SSD was biphasic: in one population males and females exhibited the same body size, whereas, in two other populations, females were larger than males. Mean straight-line carapace lengths of males and females were not statistically different at Oued Ksob (SDI = 0.08), and females were relatively small. In contrast, females from Oued Zat were significantly larger than males (SDI = 0.56) and females were larger than those from Oued Ksob. SSD was most dramatic at Oued Draa (SDI = 0.92) and much greater than any value previously reported for the species, with females exhibiting a mean carapace length greater than those in the other 2 rivers.

Prior to the drought, groundwater was used primarily for irrigation and the power plant relied exclusively on surface water stored in a nearby reservoir for cooling. Seepage from the reservoir system during the past [not, vert, similar]75 a has resulted in the buildup of a large mound of water in the underlying unconfined aquifer. A well field was installed during the drought for the purpose of tapping the groundwater mound as a supplemental source of water for cooling. Concentrations of dissolved Cl super(-) and [Display omitted] indicate 65-100% of shallow groundwater and 0-100% of deep groundwater (saturated thickness [not, vert, similar]115 m) in the immediate vicinity of the reservoir was from seepage out of the reservoir system. Hydrogen and O isotopic data indicate most surface-water seepage occurred in the late spring and early summer when reservoir stage was at its highest level. Tritium/ super(3)He apparent groundwater ages imply horizontal flow velocities from the reservoir were on the order of 60-600 m/a. These diverse data provided information regarding the spatial distribution, timing, and rate of seepage from the reservoir that could not have been obtained from the available geologic, hydraulic head, and conductivity data. In particular, mixing fractions of surface water and regional groundwater in the aquifer could not have been determined using hydraulic information. Mixing fractions were of special interest in this study because of the management objective to maximize the capture of surface-water seepage in the cooling water wells. Groundwater-flow models developed as well-field management tools were calibrated using inverse modeling techniques and observations of groundwater age, surface-water flow, reservoir stage, and groundwater levels. The age data only accounted for 6 of the 2574 field observations used to calibrate the groundwater-flow models, yet they were among the most influential for refining estimates of hydraulic conductivity, recharge, and seepage from the reservoir. Results from this study demonstrate the benefits of using geochemical, isotopic, and age tracer data to develop conceptual and numerical models of groundwater flow for the purpose of water management.

The morphology and age of a 2.19X10 (super 6) m (super 3) rock avalanche deposit beneath El Capitan in Yosemite Valley indicates a massive prehistoric failure of a large expanse of the southeast face. Geologic mapping of the deposit and the cliff face constrains the rock avalanche source to an area near the summit of approximately 8.5X10 (super 4) m (super 2) . The rock mass free fell approximately 650 m, reaching a maximum velocity of 100 m s (super -1) , impacted the talus slope and spread across the valley floor, extending 670 m from the base of the cliff. Cosmogenic beryllium-10 exposure ages from boulders in the deposit yield a mean age of 3.6+ or -0.2 ka. The approximately 13 kyr time lag between deglaciation and failure suggests that the rock avalanche did not occur as a direct result of glacial debuttressing. The approximately 3.6 ka age for the rock avalanche does coincide with estimated late Holocene rupture of the Owens Valley fault and/or White Mountain fault between 3.3 and 3.8 ka. The coincidence of ages, combined with the fact that the most recent (AD 1872) Owens Valley fault rupture triggered numerous large rock falls in Yosemite Valley, suggest that a large magnitude earthquake (> or =M7.0) centered in the south-eastern Sierra Nevada may have triggered the rock avalanche. If correct, the extreme hazard posed by rock avalanches in Yosemite Valley remains present and depends on local earthquake recurrence intervals. Published in 2010 by John Wiley & Sons, Ltd.

AN - 733939259; 20232247 AB - The purpose of this experiment was to use mallards (Anas platyrhynchos) tested under controlled conditions to determine how much harm to reproduction resulted from various concentrations of mercury in eggs. Breeding pairs of mallards were fed a control diet or diets containing 1, 2, 4, or 8 microg/g mercury, as methylmercury chloride. Mean concentrations of mercury in eggs laid by parents fed 0, 1, 2, 4, or 8 microg/g mercury were 0.0, 1.6, 3.7, 5.9, and 14 microg/g mercury on a wet-weight basis. There were no signs of mercury poisoning in the adults, and fertility and hatching success of eggs were not affected by mercury. Survival of ducklings and the number of ducklings produced per female were reduced by the 4 and 8-microg/g dietary mercury treatments (that resulted in 5.9 and 14 microg/g mercury in their eggs, respectively). Ducklings from parents fed the various mercury diets were just as heavy as controls at hatching, but by 6 days of age ducklings whose parents had been fed 4 or 8 microg/g mercury weighed less than controls. Because we do not know if absorption of mercury from our diets would be the same as absorption from natural foods, the mercury concentrations we report in eggs may be more useful in extrapolating to possible harmful effects in nature than are the dietary levels we fed. We conclude that mallard reproduction does not appear to be particularly sensitive to methylmercury.

AN - 733938489; 20217222 AB - Behavioral effects resulting from exposure to dietary methylmercury (MeHg) have been reported in studies of several wildlife species. However, quantifying the impact of contaminant exposure on wild populations is complicated by the confounding effects of other environmental stressors. We controlled confounding stressors in a laboratory study to quantify the level of dietary MeHg exposure associated with negative effects on the fitness of captive-reared common loon (Gavia immer) chicks. We evaluated the effect of MeHg on loon chick behavior by employing several assays, including measures of righting reflexes, responsiveness to taped parental calls, reaction to frightening stimuli, and estimates of time activity budgets. Evidence suggested that as chicks aged, those exposed to nominal dietary dose levels of 0.4 and 1.2 microg Hg/g wet-weight in food (average estimated delivered dietary level of 0.55 and 1.94 microg Hg/g, respectively) were less likely (p or =37 days old) compared to chicks on the control diet. We detected differences (p < 0.05) in several response variables with respect to source of eggs. Chicks from nests on low-pH lakes tended to spend more time on resting platforms, spent less time in the shade, were more likely to walk across a platform upon release and do it quicker, were less responsive to a frightening stimulus, and exhibited less intense response to parental wail calls than did chicks from neutral pH-lakes. Rapid MeHg excretion during feather growth likely provides loon chicks protection from MeHg toxicity and may explain the lack of behavioral differences with dietary intake. Lake source effects suggest that in ovo exposure to MeHg or other factors related to lake pH have consequences on chick behavior.

We focused on the savanna-derived cropland in northern Ghana to simulate its sensitivity to projected climate change and nitrogen fertilization scenarios. Here we show that progressive warming-drying stress over the twenty-first century will enhance soil carbon emissions from all kinds of lands of which the natural ecosystems will be more vulnerable to variation in climate variables, particularly in annual precipitation. The carbon emissions from all croplands, however, could be mitigated by applying nitrogen fertilizer at 30-60kg N ha super(-1) year super(-1). The uncertainties of soil organic carbon budgets and crop yields depend mainly on the nitrogen fertilization rate during the first 40years and then are dominated by climate drying stress. The replenishment of soil nutrients, especially of nitrogen through fertilization, could be one of the priority options for policy makers and farm managers as they evaluate mitigation and adaptation strategies of cropping systems and management practices to sustain agriculture and ensure food security under a changing climate.

The development of restoration strategies for those alterations requires fundamental information, including the use of large deep channels by fishes. We trawled within parallel paths distributed across the width of the main-channel trough of the Mississippi River to identify how the lateral distribution of fishes responds to variations in flow ranging from 50% to 200% of the annual median, water temperature ranging from 9 to 29?C and commercial shipping traffic ranging from 0 to 9 vessels per day. Among the species we encountered, only shovelnose sturgeon (Scaphirhynchus platorynchus) were persistent channel residents that remained concentrated along the main-channel centreline regardless of flow, temperature and traffic. Other persistent residents showed no distinct pattern in lateral distribution, concentrated along the deep channel margins or varied in lateral distribution with flow. Surprisingly, large adult bluegill (Lepomis macrochirus), which are conventionally viewed as limnophils, were the second-most abundant species in our samples and became increasingly abundant within the deep channel trough as flow decreased below the annual median. Clearly, those fishes exploit resources contained in the main channel and are, therefore, better viewed as opportunistic limno-rheophils. Our results imply the existence of poorly understood food resources in the main channel. We conjecture that re-creation of free-flowing secondary channels and features that increase the production and transport of invertebrates in channels can help mitigate adverse effects of channel alteration and commercial shipping.

14133727 AB - Procapra przewalskii (Buechner, 1891), commonly called Przewalski's gazelle, is polytypic with 1 of the 2 subspecies (P. p. diversicornis) likely extinct. The species now occurs only in the Qinghai Lake region in northeastern Qinghai Province, western China, and predominately inhabits semiarid grassland steppe, stable sand dunes, and the desert-shrub ecotone between them. Numbers and distribution of P. przewalskii have decreased severely from historic levels, and up to 10 small and disjunct populations are vulnerable because of agricultural usurpation of preferred habitat, competition with livestock, and illegal hunting. Total population is perhaps as high as 1,000-1,300 individuals. It is a Class I species and listed as "Critically Endangered" in China and considered "Endangered" by the International Union for Conservation of Nature and Natural Resources. It is arguably among the most endangered large mammals on earth.

This event appears to be the largest sediment transport event on record for a Southern California river. Over 170m of local shoreline (mean high water (MHW)) progradation was observed as a result of the flood, followed by 3years of rapid local shoreline recession. During this post-flood stage, linear regression-determined shoreline change rates are up to 45m super(-1) on the subaerial beach (MHW) and 4m super(-1) on the submarine delta (6m isobath). Starting approximately 1km downdrift of the river mouth, shoreline progradation persisted throughout the 3-year post-flood monitoring period, with rates up to +19m super(-1). Post-flood bathymetric surveys show nearshore (0 to 12m depth) erosion on the delta exceeding 400m3/m super(-1), more than an order of magnitude higher than mean seasonal cross-shore sediment transport rates in the region. Changes were not constant with depth, however; sediment accumulation and subsequent erosion on the delta were greatest at a5 to a8m, and accretion in downdrift areas was greatest above -2m. Thus, this research shows that the topographic bulge (or "wave") of sediment exhibited both advective and diffusive changes with time, although there were significant variations in the rates of change with depth. The advection and diffusion of the shoreline position was adequately reproduced with a simple "one line" model, although these modeling techniques miss the important cross-shore variations observed in this area. This study illustrates the importance of understanding low-frequency, high volume coastal discharge events for understanding short- and long-term sediment supply, littoral transport, and beach and nearshore evolution in coastal systems adjacent to river mouths.

2011-079050 AB - Fifty-two soils under black spruce [Picea mariana (Mill.) Britton et al.]-dominated forest communities were examined and assessed for their organic C (OC) stores in relation to soil characteristics. Study sites were located on a variety of parent materials, landscape positions, and drainage conditions. Results indicate that soils at most sites were weakly developed, commonly with organic (O) horizons ranging from 3 to 39 cm (> or =100 cm occasionally). Organic C stores tended to increase as drainage changed from somewhat excessive and well to very poorly drained (average to 1 m: 12.6-50.9 kg OC m (super -2) , respectively). The lowest OC store for an individual site was 7.1 kg OC m (super -2) in a well-drained soil on an outwash plain and the highest was 109 kg C m (super -2) in a very poorly drained soil. Surface organic horizons contained 13 to 100% of the total pedon OC stores. In Gelisols, permafrost sequestered an average of 9, 19, and 39% of SOC stores for the somewhat poorly, poorly, and very poorly drained soils, respectively. The presence of permafrost in poorly drained sites increased average OC stores from 27.8 to 50.1 kg OC m (super -2) over those without permafrost. Soil bulk density, cation exchange capacity, and extractable acidity assessed in relation to OC stores of genetic horizons illustrate the significant impact of OC on soil properties. In previous ecological studies in Alaska, OC was determined for only the surface horizons; our data suggest that such shallow sampling may underestimate total OC stores by an average of 26% and up to 68%.

We experimentally quantified the effects of central stoneroller minnows (Campostoma anomalum (Rafinesque) and Meek's crayfish (Orconectes meeki meeki (Faxon)) on benthic communities using electric exclusion quadrats in Little Mulberry Creek before (June) and during (August) seasonal stream drying. Unglazed ceramic tiles were deployed in June and August to measure periphyton and invertebrate abundance, and leafpack decomposition and primary production were also measured in August. Relationships between stoneroller and crayfish density and the size of consumer effects were evaluated with multiple linear regression models. Average chlorophyll a abundance was greater on exposed than exclusion tiles in August, but not in June. Sediment dry mass, periphyton ash-free dry mass (AFDM), and chironomid densities on tiles did not differ among treatments in either period. Leaf packs decayed faster in exposed than exclusion treatments (k sub(exposed)=0.038k sub(exclusion)=0.007), but consumer effects were stronger in some pools than others. Leafpack invertebrate biomass and abundance and tile primary productivity did not differ among treatments. Consumer effects on chlorophyll a were related to crayfish and stoneroller density, and effects on chironomid density were related to stoneroller density. These results contrast with a previous exclusion experiment in Little Mulberry Creek that demonstrated strong consumer effects. The influence of stream drying on consumer effects appears to have been reduced by strong spates, underscoring the importance of conducting multi-year studies to determine the magnitude of variability in ecological interactions.

Turtles ranged in size from 33.4 to 67.5 cm straight carapace length (45.7 +/- 12.9 cm) and 4.4 to 40.8 kg in mass (16.0 +/- 13.8 kg). These data represent the first satellite tracking data gathered on juveniles of this endangered species at this remote study site, which may represent an important developmental habitat and foraging ground. Satellite tracking results suggested that these immature turtles were resident for several months very close to capture and release sites, in waters from 0 to 10 m in depth. Mean home range for this springtime tracking period as represented by minimum convex polygon (MCP) was 1004.9 +/- 618.8 km super(2) (range 374.1 to 2060.1 km super(2)), with 4 of 6 individuals spending a significant proportion of time within the ENP boundaries in 2008 in areas with dense patches of marine algae. Core use areas determined by 50% kernel density estimates (KDE) ranged from 5.0 to 54.4 km super(2), with a mean of 22.5 +/- 22.1 km super(2). Overlap of 50% KDE plots for 6 turtles confirmed use of shallow-water nearshore habitats <0.6 m deep within the park boundary. Delineating specific habitats used by juvenile green turtles in this and other remote coastal areas with protected status will help conservation managers to prioritize their efforts and increase efficacy in protecting endangered species.

AN - 853485869; 14131696 AB - Sediment budget analyses conducted for annual to decadal timescales report variable magnitudes of littoral transport along the south shore of Long Island, New York. It is well documented that the primary transport component is directed alongshore from east to west, but relatively little information has been reported concerning the directions or magnitudes of cross-shore components. Our review of budget calculations for the Fire Island coastal compartment (between Moriches and Fire Island Inlets) indicates an average deficit of 217,700 m3/y. Updrift shoreline erosion, redistribution of nourishment fills, and reworking of inner-shelf deposits have been proposed as the potential sources of additional sediment needed to rectify budget residuals. Each of these sources is probably relevant over various spatial and temporal scales, but previous studies of sediment texture and provenance, inner-shelf geologic mapping, and beach profile comparison indicate that reworking of inner-shelf deposits is the source most likely to resolve budget discrepancies over the broadest scales. This suggests that an onshore component of sediment transport is likely more important along Fire Island than previously thought. Our discussion focuses on relations between geomorphology, inner-shelf geologic framework, and historic shoreline change along Fire Island and the potential pathways by which reworked, inner-shelf sediments are likely transported toward the shoreline.

DO - http://dx.doi.org/10.2112/08-1140.1 ER - TY - JOUR T1 - Hazards Affecting Grizzly Bear Survival in the Greater Yellowstone Ecosystem AN - 853481218; 14133447 AB - During the past 2 decades, the grizzly bear (Ursus arctos) population in the Greater Yellowstone Ecosystem (GYE) has increased in numbers and expanded its range. Early efforts to model grizzly bear mortality were principally focused within the United States Fish and Wildlife Service Grizzly Bear Recovery Zone, which currently represents only about 61% of known bear distribution in the GYE. A more recent analysis that explored one spatial covariate that encompassed the entire GYE suggested that grizzly bear survival was highest in Yellowstone National Park, followed by areas in the grizzly bear Recovery Zone outside the park, and lowest outside the Recovery Zone. Although management differences within these areas partially explained differences in grizzly bear survival, these simple spatial covariates did not capture site-specific reasons why bears die at higher rates outside the Recovery Zone. Here, we model annual survival of grizzly bears in the GYE to 1) identify landscape features (i.e., foods, land management policies, or human disturbances factors) that best describe spatial heterogeneity among bear mortalities, 2) spatially depict the differences in grizzly bear survival across the GYE, and 3) demonstrate how our spatially explicit model of survival can be linked with demographic parameters to identify source and sink habitats. We used recent data from radiomarked bears to estimate survival (1983-2003) using the known-fate data type in Program MARK. Our top models suggested that survival of independent (age greater than or equal to 2yr) grizzly bears was best explained by the level of human development of the landscape within the home ranges of bears. Survival improved as secure habitat and elevation increased but declined as road density, number of homes, and site developments increased. Bears living in areas open to fall ungulate hunting suffered higher rates of mortality than bears living in areas closed to hunting. Our top model strongly supported previous research that identified roads and developed sites as hazards to grizzly bear survival. We also demonstrated that rural homes and ungulate hunting negatively affected survival, both new findings. We illustrate how our survival model, when linked with estimates of reproduction and survival of dependent young, can be used to identify demographically the source and sink habitats in the GYE. Finally, we discuss how this demographic model constitutes one component of a habitat-based framework for grizzly bear conservation. Such a framework can spatially depict the areas of risk in otherwise good habitat, providing a focus for resource management in the GYE.

Developing an understanding of these systems is essential for managing these resources. However, physical characterization of these systems can be challenging, with many occurring in remote areas where the use of typical methods for assessing aquifer parameters is difficult or impossible. Analyses of surface river discharge data, coupled with available surface geology data, can provide initial insight into and quantification of the extent and role of mountain aquifers within river systems. These methods were applied to available river discharge data from seven sub-basins in the Southern Sierra Nevada of California to characterize the role of groundwater in basin hydrology. Hydrograph characteristics of each drainage basin were compared with areal extents of various bedrock and non-fractured rock aquifers to estimate their role in maintaining baseflow discharge in the surface rivers. These data suggest that basins with significant amounts of karst have a substantial long-term storage component to the system. These data also suggest that basins with significant amounts of unconsolidated material (glacial deposits, talus, and alluvium) show a similar trend in groundwater storage.

From 2002 to 2007 we have mapped the terminus position and measured the surface ablation from the terminus region up-glacier to the snowline in the Bagley Ice Field. Since the last surge the terminus has retreated, primarily by calving, approximately 0.4-0.5 km/a, and the terminus position is at the 1992 pre-surge position. The glacier surface in the terminus region is presently downwasting by melting at approximately 8-10 m/a and 3.5-6.0 m/a at the approximate altitude of the equilibrium line, 1200 m. The average daily melt for Bering Glacier is approximately 4-5 cm/d at mid-glacier, and this melt rate appears to be steady, regardless of insulation and/or precipitation. The melt from the Bering Lobe of the glacier system generates between 8 and 15 km (super 3) of fresh water yearly, which flows directly into the Gulf of Alaska via the Seal River, potentially affecting its circulation and ecosystem. Elevation measurements from 1957 compared with our measurements made in 2004, combined with bed topography from ice penetrating radar, show that the Bering Lobe has lost approximately 13% of its total mass.

The Gulf of Alaska's coast was one leg of a long coastal migration route that was likely used by the first Native Americans entering North America more than 11,000 a ago, before an ice free corridor through the interior was open. Yet, although there is ample evidence of Native Alaskan occupations in the area at the time of their contact with the first European explorers in the mid to late 1700s, as well as subsequent habitation of the area by European and Euro-American fur traders, fishermen, and miners, there is no documented evidence for the prehistoric human use of this section of coastline. There are several possible reasons for this, including the harshness of the Gulf of Alaska's weather and seas. However, the main cause for this lack of information is the fact that there has been no systematic archaeological work in the area. Similarly, modern subsistence uses in the area are unstudied, and only anecdotal reports of current subsistence practices in the Bering Glacier vicinity are available for researchers.

Conductivity profiles from Berg Lake, perched 135 m above sea level (a.s.l.), show no salt in the lake, but the temperature profiles indicate an apparently unstable situation: the 4 degrees C density maximum lies at 10 m depth, not at the bottom of the lake (90 m depth). Subglacial discharge from the Steller Glacier into the bottom of the lake must inject a suspended sediment load sufficient to marginally stabilize the water column throughout the lake. In Vitus Lake, terminus positions derived from satellite imagery show that the glacier terminus rapidly retreated from 1995 to the present, resulting in a substantial expansion of the volume of Vitus Lake. Conductivity and temperature profiles from the tidally influenced Vitus Lake show a complex four-layer system with diluted ( approximately 50%) seawater in the bottom of the lake. This lake has a complex vertical structure that is the result of convection generated by ice melting in salt water, stratification within the lake, and fresh water entering the lake from beneath the glacier and surface runoff. Four consecutive years, 2001 through 2004, of these observations in Vitus Lake show little change in the deep temperature and salinity conditions, indicating limited deep water renewal. The combination of the lake level measurements with discharge measurements, through a tidal cycle, by an Acoustic Doppler Current Profiler (ADCP) deployed in the Seal River, which drains the entire Bering system, showed a strong tidal influence but no seawater entry into Vitus Lake. The ADCP measurements, combined with lake level measurements, established a relationship between lake level and discharge, which when integrated over a tidal cycle gave a tidally averaged discharge ranging from 1310 to 1510 m (super 3) s (super -1) .

Applications of glacier remote sensing include, but are not limited to, mapping extent and features, ice velocities through sequential observations, glacier terminus locations, snow line location, glacier albedo, changes in glacier volume, iceberg surveys and calving rates, hydrographic and water quality parameters in ice marginal lakes, and land-cover classification maps. Historical remote sensing images provide a much needed geospatial time record of the dynamic changes that Bering Glacier has undergone, including changes from its surge behavior and response to climate change. Remote sensing images dating back to the early 1990s have been used to map the glacier terminus retreat of approximately 5 to 7 km, which has resulted in Vitus Lake increasing in volume 9.4 km (super 3) ( approximately 260%) from 1995 to 2006. Using elevation data obtained from remote sensing and GPS surface points, we have determined that the glacier elevation has decreased by approximately 150 m at the terminus and 30 m at the equilibrium line ( approximately 1300 m) since 1972. Satellite observations have recorded the upward migration in altitude of the equilibrium line to its present (2006) position (slightly >1200 m). The decrease in glacier volume, obtained using remote sensing-derived elevation data, from 1957 to 2004 is estimated at approximately 104 km (super 3) . Remote sensing data also have mapped the sediment-rich (rock flour) water flowing into Vitus Lake, providing insight into the hydrologic circulation of the Bering Glacier System, showing major glacier discharge from the Abandoned River, Arrowhead Point, and Lamire Bay in the area of Vitus Lake west of Taggland.

Analysis for these dyes in the hydrocarbon product is difficult due to their very low concentrations in such a complex matrix. Flow injection analysis/electrospray ionization/mass spectrometry in both negative and positive mode was used to optimize ionization of ten typical solvent dyes. Samples of hydrocarbon product were analyzed under similar conditions. Positive electrospray ionization produced very complex spectra, which were not suitably specific for targeting only the dyes. Negative electrospray ionization produced simple spectra because aliphatic and aromatic moieties were not ionized. This enabled screening for a target dye in samples of hydrocarbon product from a spill.

The RKT is a robust, nonparametric test that provides an increased power of trend detection by grouping data from multiple sites within a given geographic region. The RKT analyses indicated strong, pervasive trends in snowmelt and streamflow timing, which have shifted toward earlier in the year by a median of 2-3 weeks over the 29-yr study period. In contrast, relatively few statistically significant trends were detected using simple linear regression. RKT analyses also indicated that November-May air temperatures increased by a median of 0.9C decade super(-1), while 1 April SWE and maximum SWE declined by a median of 4.1 and 3.6 cm decade super(-1), respectively. Multiple linear regression models were created, using monthly air temperatures, snowfall, latitude, and elevation as explanatory variables to identify major controlling factors on snowmelt timing. The models accounted for 45% of the variance in snowmelt onset, and 78% of the variance in the snowmelt center of mass (when half the snowpack had melted). Variations in springtime air temperature and SWE explained most of the interannual variability in snowmelt timing. Regression coefficients for air temperature were negative, indicating that warm temperatures promote early melt. Regression coefficients for SWE, latitude, and elevation were positive, indicating that abundant snowfall tends to delay snowmelt, and snowmelt tends to occur later at northern latitudes and high elevations. Results from this study indicate that even the mountains of Colorado, with their high elevations and cold snowpacks, are experiencing substantial shifts in the timing of snowmelt and snowmelt runoff toward earlier in the year.

Reductions of sea ice projected to occur in the Arctic by mid-century raise concerns for conservation of the Pacific walrus. To understand the significance of sea ice loss to the viability of walruses, it would be useful to better understand the spatial associations between the movements of sea ice and walruses. We investigated whether local-scale (~1 to 100 km) walrus movements correspond to movements of sea ice in the Bering Sea in early spring, using locations from radio-tracked walruses and measures of ice floe movements from processed synthetic aperture radar satellite imagery. We used generalized linear mixed-effects models to analyze the angle between walrus and ice floe movement vectors and the distance between the final geographic position of walruses and their associated ice floes (displacement), as functions of observation duration, proportion of time the walrus was in water, and geographic region. Analyses were based on 121 walrus-ice vector pairs and observations lasting 12 to 36 h. Angles and displacements increased with observation duration, proportion of time the walrus spent in the water, and varied among regions (regional mean angles ranged from 40 to 81 and mean displacements ranged from 15 to 35 km). Our results indicated a lack of correspondence between walruses and their initially associated ice floes, suggesting that local areas of walrus activities were independent of the movement of ice floes.

Previously we demonstrated that introduced Chinook salmon from Lake Michigan, Wisconsin (WI), USA, have higher survival following R. salmoninarum challenge relative to the progenitor stock from Green River, Washington, USA. In the present study, we investigated the pathological and immunological responses that are associated with differential survival in the 2 Chinook salmon stocks following intra-peritoneal R. salmoninarum challenge of 2 different cohort years (2003 and 2005). Histological evaluation revealed delayed appearance of severe granulomatous lesions in the kidney and lower overall prevalence of membranous glomerulopathy in the higher surviving WI stock. The higher survival WI stock had a lower bacterial load at 28 d post-infection, as measured by reverse-transcriptase quantitative polymerase chain reaction (RT-qPCR). However, at all other time points, bacterial load levels were similar despite higher mortality in the more susceptible Green River stock, suggesting the possibility that the stocks may differ in their tolerance to infection by the bacterium. Interferon-gamma, inducible nitric oxide synthase (iNOS), Mx-1, and transferrin gene expression were up-regulated in both stocks following challenge. A trend of higher iNOS gene expression at later time points (=>28 d post-infection) was observed in the lower surviving Green River stock, suggesting the possibility that higher iNOS expression may contribute to greater pathology in that stock.

The method involves temporary shutdown of individual pumps in wells of the P&T system. Conducting aquifer tests in this manner has several advantages, including (1) no additional contaminated water is withdrawn, and (2) hydraulic containment of contaminants remains largely intact because pumping continues at most wells. The well-shutdown test method was applied at the former Naval Air Warfare Center (NAWC), West Trenton, New Jersey, where a P&T operation is designed to contain and remove trichloroethene and its daughter products in the dipping fractured sedimentary rocks underlying the site. The detailed site-scale subsurface geologic stratigraphy, a three-dimensional MODFLOW model, and inverse methods in UCODE_2005 were used to analyze the shutdown tests. In the model, a deterministic method was used for representing the highly heterogeneous hydraulic conductivity distribution and simulations were conducted using an equivalent porous media method. This approach was very successful for simulating the shutdown tests, contrary to a common perception that flow in fractured rocks must be simulated using a stochastic or discrete fracture representation of heterogeneity. Use of inverse methods to simultaneously calibrate the model to the multiple shutdown tests was integral to the effectiveness of the approach.

Land managers are faced with making cost-effective plans to remediate mine influences. Remediation plans are facilitated by spatial mass-loading profiles that indicate the locations of metal mass-loading, seasonal changes, and the extent of biogeochemical processes. Field-scale experiments during both low- and high-flow conditions and time-series data over diel cycles illustrate how this can be accomplished. A low-flow experiment provided spatially detailed loading profiles to indicate where loading occurred. For example, [Display omitted] was principally derived from sources upstream from the study reach, but three principal locations also were important for [Display omitted] loading within the reach. During high-flow conditions, Lagrangian sampling provided data to interpret seasonal changes and indicated locations where snowmelt runoff flushed metals to the stream. Comparison of metal concentrations between the low- and high-flow experiments indicated substantial increases in metal loading at high flow, but little change in metal concentrations, showing that toxicity at the most downstream sampling site was not substantially greater during snowmelt runoff. During high-flow conditions, a detailed temporal sampling at fixed sites indicated that Zn concentration more than doubled during the diel cycle. Monitoring programs must account for diel variation to provide meaningful results. Mass-loading studies during different flow conditions and detailed time-series over diel cycles provide useful scientific support for stream management decisions.

The 52,000-km super(2) Central Valley aquifer system consists of heterogeneous valley-fill deposits. The texture model was developed by compiling and analyzing approximately 8,500 drillers' logs, describing lithologies up to 950m below land surface. The lithologic descriptions on the logs were simplified into a binary classification of coarse- and fine-grained. The percentage of coarse-grained sediment, or texture, was then computed for each 15-m depth interval. The model was developed by 3D kriging of the percentage of coarse-grained deposits onto a 1.6-km spatial grid at 15-m depth intervals from land surface down to 700m below land surface. The texture model reflects the known regional, spatial, and vertical heterogeneity in the aquifer system. The texture model correlates to sediment source areas, independently mapped geomorphic provinces, and factors affecting the development of alluvial fans, thus demonstrating the utility of using tcdrillers' logs as a source of lithologic information. The texture model is upscaled to a layered groundwater flow model for use in defining the hydraulic properties of the aquifer system.Original Abstract: Un modele tridimensionnel (3D) dit ' de texture ' a ete developpe pour aider a la caracterisation de l'aquifere de la Vallee Centrale en Californie (Etats-Unis) par un modele hydrodynamique. Les 52,000km super(2) de l'aquifere de la Vallee Centrale sont constitues de depots heterogenes de remblayage de vallees. Le modele de texture a ete developpe en combinant et analysant environ 8500 logs de sondage et en decrivant les lithologies jusqu'a plus de 950m sous la surface du sol. Les descriptions lithologiques des logs ont ete simplifiees en une classification binaire grains grossiers et grains fins. Le pourcentage de sediment grossier, ou texture, a ensuite ete calcule pour chaque intervalle de profondeur de 15m. Le modele a ete developpe avec un kriging 3D du pourcentage de grain grossier dans les depots dans une grille de 1.6km de cote pour des intervalles de profondeur de 15m et jusqu'a 700m sous la surface du sol. Le modele de texture reflete l'heterogeneite regionale, spatiale et verticale connue du systeme aquifere. Le modele de texture se correle avec la localisation des sources de sediments, les provinces geomorphologiques independamment cartographiees et les facteurs influencant le developpement des cones alluviaux, montrant ainsi l'utilite d'utiliser les logs de sondage comme source d'information lithologique. Le modele de texture est ensuite utilise dans un modele d'ecoulement de l'eau souterraine a couches afin de permettre la determination des proprietes hydrauliques de l'aquifere.

Such event processes may be modulated simultaneously over several spatial (e.g., latitude and longitude) and temporal (e.g., age, calendar time, and cohort) dimensions. The ecological challenge is to understand the dynamic latent processes that were integrated over several dimensions (space and time) to produce the observed pattern: a so-called inverse problem. An example of such a problem is characterizing epidemiological rate processes from spatially referenced age-specific prevalence data for a wildlife disease such as chronic wasting disease (CWD). With age-specific prevalence data, the exact infection times are not observed, which complicates the direct estimation of rates. However, the relationship between the observed data and the unobserved rate variables can be described with likelihood equations. Typically, for problems with multiple timescales, the likelihoods are integral equations without closed forms. The complexity of the likelihoods often makes traditional maximum-likelihood approaches untenable. Here, using seven years of hunter-harvest prevalence data from the CWD epidemic in white-tailed deer (Odocoileus virginianus) in Wisconsin, USA, we develop and explore a Bayesian approach that allows for a detailed examination of factors modulating the infection rates over space, age, and time, and their interactions. Our approach relies on the Bayesian ability to borrow strength from neighbors in both space and time. Synthesizing a number of areas of event time analysis (current-status data, age/period/cohort models, Bayesian spatial shared frailty models), our general framework has very broad ecological applicability beyond disease prevalence data to a number of important ecological event time analyses, including general survival studies with multiple time dimensions for which existing methodology is limited. We observed strong associations of infection rates with age, gender, and location. The infection rate appears to be increasing with time. We could not detect growth hotspots, or location by time interactions, which suggests that spatial variation in infection rates is determined primarily by when the disease arrives locally, rather than how fast it grows. We emphasize assumptions and the potential consequences of their violations.

Detailed habitat-specific models have been developed to predict plant responses to fire, but these models generally ignore the breadth of fire regime characteristics that can influence plant survival such as the degree and duration of exposure to lethal temperatures. We provide a decision framework that integrates fire regime components, plant growth form, and survival attributes to predict how plants will respond to fires and how fires can be prescribed to enhance the likelihood of obtaining desired plant responses. Fires are driven by biotic and abiotic factors that dictate their temporal (seasonality and frequency), spatial (size and patchiness), and magnitude (intensity, severity, and type) components. Plant resistance and resilience to fire can be categorized by a combination of life form, size, and ability to disperse or protect seeds. We use a combination of life form and vital plant attributes along with an understanding of fire regime components to suggest a straightforward way to approach the use of fire to either reduce or enhance particular species. A framework for aiding decisions is organized by life form and plant size. Questions regarding perennating bud and seed characteristics direct restoration practitioners to fire regimes that may achieve their management objectives of either increasing or decreasing plants with specific life form characteristics.

In this study, we investigate the relationships among physical, benthic, and fish variables in an effort to help explain the distribution patterns of organisms on patch reefs within Biscayne National Park, FL, USA. We visited a total of 196 randomly selected sampling stations on 12 shallow (<10m) patch reefs and measured physical variables (e.g., substratum rugosity, substratum type) and benthic and fish community variables. We also incorporated data on substratum rugosity collected remotely via airborne laser surveying (Experimental Advanced Airborne Research Lidar-EAARL). Across all stations, only weak relationships were found between physical, benthic cover, and fish assemblage variables. Much of the variance was attributable to a 'reef effect,' meaning that community structure and organism abundances were more variable at stations among reefs than within reefs. However, when the reef effect was accounted for and removed statistically, patterns were detected. Within reefs, juvenile scarids were most abundant at stations with high coverage of the fleshy macroalgae Dictyota spp., and the calcified alga Halimeda tuna was most abundant at stations with low EAARL rugosity. Explanations for the overwhelming importance of 'reef' in explaining variance in our dataset could include the stochastic arrangement of organisms on patch reefs related to variable larval recruitment in space and time and/or strong historical effects due to patchy disturbances (e.g., hurricanes, fishing), as well as legacy effects of prior residents ('priority' effects).

Onshore mapping commonly documents missing or only narrow terranes of former forearc rock and the inboard migration of the arc magmatic front. These observations are evidence that subduction is accompanied by the removal of sediment and crustal material from the submerged forearc by the kindred tectonic processes, respectively, of sediment subduction and subduction erosion. Subduction erosion truncates the margin (migrates the trench inboard) at ~2.5 km/Ma. Onshore observations at ancient crust-suturing subduction zones (CSSZs) imply that collisional suturing is accompanied by sediment subduction and truncation of both upper and lower plates. During a protracted period of suturing (20-50 million years), a 100-200 km wide (or wider) band of the seaward edge of each plate can be removed subductively. Truncation of the upper plate is effected by subduction erosion, and that of the lower plate by the necking and break-off of its subducted edge. The average linear rate of crustal loss for each plate is estimated at ~1.5 km/Ma, or ~3 km/Ma combined. Because significant crustal loss occurs before and during tectonic fusing of colliding crustal blocks, structures and rock bodies that might be expected to record a former OMSZ and the formation of a CSSZ may be absent, unimpressively small, or preserved only as exhumed masses of once deeply subducted material.Original Abstract: Des observations au large a des zones modernes de subduction de marge oceanique revelent que des amas de materiel accrete ont frequemment une petite taille volumetrique ou sont manquants, qu'il s'est produit un amincissement de la croute et de la subsidence (3-5 km) et que la plupart des axes des tranchees reposent a proximite (5-30 km) de la bordure, a epaisseur decroissante, du socle rocheux de la cote. La cartographie du continent signale souvent des terranes manquants ou seulement etroits, d'anciennes roches d'avant-arc et la migration vers le continent du front magmatique de l'arc. Ces observations constituent des preuves que la subduction est accompagnee du retrait de materiel sedimentaire et de la croute de l'avant-arc submerge par des processus tectoniques apparentes, respectivement de subduction de sediments et d'erosion de la subduction. L'erosion de la subduction tronque la bordure (fait migrer la tranchee vers le continent) a un taux d'environ 2,5 km/Ma. Les observations sur le continent a des anciennes zones de subduction de suture de la croute impliquent que les sutures de collisions sont accompagnees de subduction de sediments et d'une troncation des plaques inferieures et superieures. Au cours d'une periode prolongee de suture (20-50 Ma), une bande de 100 a 200 km (ou plus large) de la bordure oceanique de chaque plaque peut etre retiree par subduction. La troncation de la plaque superieure est causee par une erosion de subduction, c'est-a-dire de la plaque inferieure par etranglement et par rupture de la bordure subductee. Le taux moyen de perte lineaire de la croute pour chaque plaque est estime a ~1,5 km/Ma ou ~3 km/Ma pour les deux ensemble. Puisqu'une importante perte de la croute a lieu avant et durant la fusion tectonique de blocs de croute en collision, les structures et les amas rocheux qui pourraient enregistrer une ancienne zone de subduction de marge oceanique et la formation de zones de subduction de suture de la croute peuvent etre manquants, tres petits ou preserves uniquement en tant que masses exhumees de materiel jadis subduit a de grandes profondeurs.

Colocated sets of CAPMoN and NADP instrumentation, consisting of precipitation collectors and rain gages, were operated simultaneously per standard protocols for each network at Sutton, Ontario and Frelighsburg, Ontario, Canada and at State College, PA, USA. CAPMoN samples were collected daily, and NADP samples were collected weekly, and samples were analyzed exclusively by each network's laboratory for pH, H super(+), Ca super(2+), Mg super(2+), Na super(+), K super(+), $\text{NH}_{4}{+}$ , Cl super(-), $\text{NO}_{3}{-}$ , and $\text{SO}_{4}{2-}$ . Weekly and annual precipitation-weighted mean concentrations for each network were compared. This study is a follow-up to an earlier internetwork comparison for the period 1986-1993, published by Alain Sirois, Robert Vet, and Dennis Lamb in 2000. Median weekly internetwork differences for 1995-2004 data were the same to slightly lower than for data for the previous study period (1986-1993) for all analytes except $\text{NO}_{3}{-}$ , $\text{SO}_{4}{2-}$ , and sample depth. A 1994 NADP sampling protocol change and a 1998 change in the types of filters used to process NADP samples reversed the previously identified negative bias in NADP data for hydrogen-ion and sodium concentrations. Statistically significant biases (a = 0.10) for sodium and hydrogen-ion concentrations observed in the 1986-1993 data were not significant for 1995-2004. Weekly CAPMoN measurements generally are higher than weekly NADP measurements due to differences in sample filtration and field instrumentation, not sample evaporation, contamination, or analytical laboratory differences.

At each of three study sites, depth-dependent samples and wellbore flow data were collected from multiple depths in selected PSWs under pumping conditions. The chemistry of these depth-dependent samples, along with samples of the surface discharge from the PSWs, was compared to that of adjacent nested monitoring wells. The results of depth-dependent analyses from sites in Modesto (California), York (Nebraska), and Tampa (Florida) are summarized and compared. Although the exact mechanisms for transport of contaminants to the PSWs varied among these hydrogeologic settings, in all three settings the presence of wells or boreholes or natural preferential flow paths allowed water and contaminants to bypass substantial portions of the aquifer and to reach PSWs or depths in the aquifer more quickly than would have occurred in the absence of these short-circuiting flow paths. The chemistry and flow data from multiple depths was essential to developing an understanding of the dominant flow paths of contaminants to PSW in all three settings. This knowledge contributes to developing effective strategies for monitoring and protection.Original Abstract: La qualite de l'eau en fonction de la profondeur et les donnees d'ecoulement de forages ont ete utilisees pour determiner la localisation et l'importance de la contamination qui penetre les puits d'alimentation en eau potable (PAEP) a l'echelle de differents aquiferes principaux des Etats-Unis.

Bien que les mecanismes exacts du transport de contaminants des PAEP variaient en fonction des conditions hydrogeologiques des sites, la presence des puits ou forages ou d'ecoulements preferentiels naturels ont permis au niveau des trois sites, a l'eau et aux contaminants d'eviter des parties significatives de l'aquifere et d'atteindre les PAEP ou des profondeurs au sein de l'aquifere de maniere plus rapide qu'en absence des ecoulements de type court-circuits. La chimie et les donnees concernant les ecoulements en differentes profondeurs etaient essentielles pour comprendre l'organisation des ecoulements dominants des contaminants au niveau des PAEP dans les trois sites.

Such a study cannot be realized at a Hg-contaminated area or under laboratory conditions but could be achieved by introducing methylmercury into breeding females and allowing them to deposit Hg in their eggs. Female mallards (Anas platyrhynchos) were intraperitoneally injected with solutions of methylmercury chloride dissolved in corn oil, propylene glycol, dimethyl sulfoxide, mineral oil, Olestra, Crisco, lard, hard paraffin, and a combination of hard and soft paraffin. In some cases, egg laying was delayed, as a result of either the solvent itself (in the case of Olestra, Crisco, and lard) or the highest concentration of methylmercury chloride (500 [mu]g/g) in some of the solvents. Mercury in eggs ranged from a control level (<0.1 [mu]g/g) to approximately 14 [mu]g/g on a wet weight basis, which more than covers the range of concentrations reported in wild bird eggs. Mercury concentrations in a series of eggs from the same female declined mostly as a result of excretion of Hg in prior eggs and not because of the length of time since the injection. Intraperitoneal injections hold promise in field studies in which one would like to study the reproductive effects of a wide range of methylmercury levels in the eggs of a wild bird and under the natural conditions that exist in the field.

Any tool that can move beyond descriptive study and helps to evaluate options for remediation in a way that maximizes improvements to the water quality of streams and minimizes cost of remediation could save valuable resources and time. A reactive solute transport model, calibrated from two detailed mass-loading studies in Little Cottonwood Creek (LCC), Utah, provides a tool to evaluate remediation options. Metal loading to LCC is dominated by discharge from two mine drainage tunnels. Discharge from an upstream tunnel has been treated by a fen to reduce metal loading. Discharge from the downstream tunnel (WDT) can be controlled because of a bulkhead that creates a mine pool. Simulations of remedial options for three compliance locations suggest that the water-quality standards for Cu and Zn at upstream and downstream compliance locations are met using various combinations of fen treatment and WDT regulation, but the complete compliance at the middle compliance location requires the highest level of fen treatment and the greatest regulation of WDT discharge. Reactive transport modeling is an useful tool for the evaluation of remedial alternatives in complex natural systems, where multiple hydrologic and geochemical processes determine metal fate.

This information is lacking for many ecosystems including the Sierra Nevada in California, USA. We investigated fuel deposition rates and stand characteristics of seven montane and four subalpine conifers in the Sierra Nevada. We collected foliage, miscellaneous bark and crown fragments, cones, and woody fuel classes from four replicate plots each in four stem diameter size classes for each species, for a total of 176 sampling sites. We used these data to develop predictive equations for each fuel class and diameter size class of each species based on stem and crown characteristics. There were consistent species and diameter class differences in the annual amount of foliage and fragments deposited. Foliage deposition rates ranged from just over 50gma2 yeara1 in small diameter mountain hemlock stands to a14300gma2 yeara1 for the three largest diameter classes of giant sequoia. The deposition rate for most woody fuel classes increased from the smallest diameter class stands to the largest diameter class stands. Woody fuel deposition rates varied among species as well. The rates for the smallest woody fuels ranged from 0.8gma2 yeara1 for small diameter stands of Jeffrey pine to 126.9gma2 yeara1 for very large diameter stands of mountain hemlock. Crown height and live crown ratio were the best predictors of fuel deposition rates for most fuel classes and species. Both characteristics reflect the amount of crown biomass including foliage and woody fuels. Relationships established in this study allow predictions of fuel loads to be made on a stand basis for each of these species under current and possible future conditions. These predictions can be used to estimate fuel treatment longevity, assist in determining fuel model transitions, and predict future changes in fuel bed characteristics.

We marked 2,968 females with passive integrated transponder (PIT) tags at multiple sites during 2001-2005 and based our assessments on direct recaptures (breeding probabilities) and passive detection with automated PIT tag readers (1st-year survival). We interpreted our data in relation to hypotheses regarding demographic influences of bat age, roost, and effects of years with unusual environmental conditions: extreme drought (2002) and arrival of a West Nile virus epizootic (2003). Conditional breeding probabilities at 6 roosts sampled in 2002-2005 were estimated as 0.64 (95% confidence interval [95% CI] = 0.53-0.73) in 1-year-old females, but were consistently high (95% CI = 0.94-0.96) and did not vary by roost, year, or prior year breeding status in older adults. Mean litter size was 1.11 (95% CI = 1.05-1.17), based on examination of 112 pregnant females by radiography. Litter size was not higher in older or larger females and was similar to results of other studies in western North America despite wide variation in latitude. First-year survival was estimated as 0.67 (95% CI = 0.61-0.73) for weaned females at 5 maternity roosts over 5 consecutive years, was lower than adult survival (0.79; 95% CI = 0.77-0.81), and varied by roost. Based on model selection criteria, strong evidence exists for complex roost and year effects on 1st-year survival. First-year survival was lowest in bats born during the drought year. Juvenile females that did not return to roosts as 1-year-olds had lower body condition indices in late summer of their natal year than those known to survive.

For example, Cu, Fe, and Zn concentrations in acid mine drainage (AMD) can range from 100Akg/L to greater than 50mg/L with sulfur species concentrations reaching greater than 1000mg/L. Routine separation of Cu, Fe and Zn from AMD, Cu-sulfide minerals and other geological matrices usually incorporates single anion exchange resin column chromatography for metal separation. During chromatographic separation, variable breakthrough of SO4 2a during anion exchange resin column chromatography into the Cu fractions was observed as a function of the initial sulfur to Cu ratio, column properties, and the sample matrix. SO4 2a present in the Cu fraction can form a polyatomic 32S-14N-16O-1H species causing a direct mass interference with 63Cu and producing artificially light I 65Cu values. Here we report the extent of the mass interference caused by SO4 2a breakthrough when measuring I 65Cu on natural samples and NIST SRM 976 Cu isotope spiked with SO4 2a after both single anion column chromatography and double anion column chromatography. A set of five 100Akg/L Cu SRM 976 samples spiked with 500mg/L SO4 2a resulted in an average I 65Cu of a3.50aAc5.42a€ ; following single anion column separation with variable SO4 2a breakthrough but an average concentration of 770Akg/L. Following double anion column separation, the average SO4 2aconcentration of 13Akg/L resulted in better precision and accuracy for the measured I 65Cu value of 0.01aAc0.02a relative to the expected 0a for SRM 976. We conclude that attention to SO4 2a breakthrough on sulfur-rich samples is necessary for accurate and precise measurements of I 65Cu and may require the use of a double ion exchange column procedure.

A critical step in this process is to put image data from different sensors onto a common radiometric scale. This work focuses on monitoring the long-term on-orbit calibration stability of the Terra Moderate Resolution Imaging Spectroradiometer (MODIS) and the Landsat 7 (L7) Enhanced Thematic Mapper Plus (ETM+) sensors using the Committee on Earth Observation Satellites (CEOS) reference standard pseudo-invariant test sites (Libya 4, Mauritania 1/2, Algeria 3, Libya 1, and Algeria 5). These sites have been frequently used as radiometric targets because of their relatively stable surface conditions temporally. This study was performed using all cloud-free calibrated images from the Terra MODIS and the L7 ETM+ sensors, acquired from launch to December 2008. Homogeneous regions of interest (ROI) were selected in the calibrated images and the mean target statistics were derived from sensor measurements in terms of top-of-atmosphere (TOA) reflectance. For each band pair, a set of fitted coefficients (slope and offset) is provided to monitor the long-term stability over very stable pseudo-invariant test sites. The average percent differences in intercept from the long-term trends obtained from the ETM+TOA reflectance estimates relative to the MODIS for all the CEOS reference standard test sites range from 2.5% to 15%. This gives an estimate of the collective differences due to the Relative Spectral Response (RSR) characteristics of each sensor, bi-directional reflectance distribution function (BRDF), spectral signature of the ground target, and atmospheric composition. The lifetime TOA reflectance trends from both sensors over 10years are extremely stable, changing by no more than 0.4% per year in its TOA reflectance over the CEOS reference standard test sites.

Case studies, using a combination of in-channel wood surveys and an air photo inventory of landslides, illustrate current conditions in a redwood-dominated watershed undergoing restoration work, and the influence of wood loading and landslides on the carbon budget. Redwood trees have extremely large biomass (trunk wood volumes of 700 to 1000m3) and are very decay-resistant; consequently, they have a large and persistent influence on in-channel wood loading. Large wood surveys indicate high wood loading in streams in uncut forests (0.3-0.5m3/m2 of channel), but also show that high wood loading can persist in logged basin with unlogged riparian buffers because of the slow decay of fallen redwoods. Through a watershed restoration program, Redwood National Park increases in-channel wood loading in low-order streams, but the effectiveness of this technique has not yet been tested by a large flood. Another unique characteristic of redwood is its ability to resprout from basal burls after cutting, so that root strength may not decline as sharply following logging as in other types of forests. An air photo inventory of landslides following a large storm in 1997 indicated: 1) that in the Redwood Creek watershed the volume of material displaced by landslides in harvested areas was not related to the time elapsed since logging, suggesting that the loss of root strength was not a decisive factor in landslide initiation, 2) landslide production on decommissioned logging roads was half that of untreated roads, and 3) landslides removed an estimated 28Mg of organic carbon/km2 from hillslopes. The carbon budget of a redwood-dominated catchment is dominated by the vegetative component, but is also influenced by the extent of mass movement, erosion control work, and in-channel storage of wood.

Increased equipment costs associated with 'chaining', and dangers associated with prescribed fires, have resulted in more instances where mechanical thinning of woodlands is being used. Our 2005 to 2006 study within Grand Staircase Escalante National Monument, Utah, examined responses of breeding birds to the mechanical reduction of pinyon-juniper woodlands within a randomized 4-block design that incorporated 11 control and nine treatment bird count stations. We surveyed birds within 3.1-ha bird-count stations (n = 20) prior to, and following, pinyon-juniper mechanical reduction treatments. Thinning in April 2006 removed a mean of 92% (+ 6.4% SE) of live trees from treatment blocks. The avian guild most greatly influenced by mechanical thinning included pinyon-juniper obligate species. Species eliminated following mechanical thinning were Gray Vireo (Vireo vicinior) and Brown-headed Cowbird (Molothrus ater), while Chipping Sparrow (Spizella passerine) numbers were significantly reduced. Birds in the shrub-nesting guild, including the sagebrush specialist Brewer's Sparrow (Spizella breweri), and habitat generalists such as the Bushtit (Psaltriparius minimus), increased in relative abundance following treatment. We conclude that mechanical thinning within the Intermountain West has the potential for natural area managers to design treatments that can influence numbers of both pinyon-juniper and sagebrush (Artemisia tridentata Nutt.) steppe avian species.

Concentrations and toxicity were assessed in streambed sediment of the San Joaquin Valley of California, one of the most productive agricultural regions of the United States. Concentrations were also measured in the suspended sediment associated with irrigation or storm-water runoff, and mass loads during storms were calculated. Western valley streambed sediments were frequently toxic to the amphipod, Hyalella azteca, with most of the toxicity attributable to bifenthrin and cyhalothrin. Up to 100% mortality was observed in some locations with concentrations of some pyrethroids up to 20 ng/g. The western San Joaquin Valley streams are mostly small watersheds with clay soils, and sediment-laden irrigation runoff transports pyrethroid insecticides throughout the growing season. In contrast, eastern tributaries and the San Joaquin River had low bed sediment concentrations (<1 ng/g) and little or no toxicity because of the preponderance of sandy soils and sediments. Bifenthrin, cyhalothrin, and permethrin were the most frequently detected pyrethroids in irrigation and storm water runoff. Esfenvalerate, fenpropathrin, and resmethrin were also detected. All sampled streams contributed to the insecticide load of the San Joaquin River during storms, but some compounds detected in the smaller creeks were not detected in the San Joaquin River. The two smallest streams, Ingram and Hospital Creeks, which had high sediment toxicity during the irrigation season, accounted for less than 5% of the total discharge of the San Joaquin River during storm conditions, and as a result their contribution to the pyrethroid mass load of the larger river was minimal.

Effects of laying order on other parameters such as egg weight, size, and lipid and moisture content also were assessed. Some effects of egg order on total polychlorinated biphenyls (PCBs) were detected, but the effect was not uniform across individual females or between years. In 2004, clutches with higher total PCBs tended to have concentrations decline across egg order, whereas clutches with lower concentrations of PCBs tended to increase across egg order. In contrast, in 2005, there was a tendency for concentrations to increase across egg order. Polychlorinated biphenyl concentrations were highly variable within and among clutches in both years. The directionality of egg order associations (i.e., slopes) for trace elements was element dependent, was positive for Mn and Zn, was negative for B, and had no slope for Cr. Whole egg weight increased across egg order. Percentage lipid was variable within a clutch, with no pattern common across all females. Percentage lipid was also correlated with organic contaminant concentration. In highly contaminated environments, higher lipid content could have the unanticipated corollary of having higher concentrations of lipophilic contaminants such as PCBs. To reduce the effect of high variation within a clutch when assessing contamination exposure, it is recommended that two eggs per clutch be collected and pooled for chemical analysis. We further recommend that, as long as the two eggs are randomly collected, the additional effort needed to identify and collect specific eggs is not warranted.

Macroinvertebrates were sampled at 21 sites to determine aquatic life impairment status (full, partial, or nonsupport) and relative biotic condition scores. Macroinvertebrate biotic condition scores were significantly correlated with cadmium, nickel, lead, zinc, and specific conductance in 2003 (r=-0.61 to -0.68) and with cadmium, lead, and pore water toxic units in 2004 (r=-0.55 to -0.57). Reference sites were fully supporting of aquatic life and had the lowest metals concentrations and among the highest biotic condition scores in both years. Sites directly downstream from mining and related activities were partially supporting, with biotic condition scores 10% to 58% lower than reference sites. Sites located greater distances downstream from mining activities had intermediate scores and concentrations of metals. Results indicate that elevated concentrations of metals originating from mining activities were the underlying cause of aquatic life impairment in several of the streams studied. There was general concurrence among the adversely affected sites in how the various indicators responded to mining activities during the overall study.

Total mercury (reported as dry weight concentrations) was highest in spotted bass (mean, 0.93 mu g/g; range, 0.16-4.41 mu g/g) and lower in bluegill (mean, 0.45 mu g/g; range, 0.22-1.96 mu g/g) and threadfin shad (0.44 mu g/g; range, 0.21-1.34 mu g/g). Spatial patterns for mercury in fish indicated high concentrations upstream in the Bear River arm and generally lower concentrations elsewhere, including downstream near the dam. These findings coincided with patterns exhibited by methylmercury in water and sediment, and suggested that mercury-laden inflows from the Bear River were largely responsible for contaminating the reservoir ecosystem. Maximum concentrations of mercury in all three fish species, but especially bass, were high enough to warrant concern about toxic effects in fish and consumers of fish.

Decisions on where and how to restore bottomland forests are complex and dependent upon landowner objectives, but for conservation of silvicolous (forest-dwelling) birds, ecologists have espoused restoration through planting a diverse mix of densely spaced seedlings that includes fast-growing species. Application of this planting strategy on agricultural tracts that are adjacent to extant forest or within landscapes that are predominately forested has been advocated to increase forest area and enhance forested landscapes, thereby benefiting area-sensitive, silvicolous birds. We measured support for these hypothesized benefits through assessments of densities of breeding birds and reproductive success of 9 species on 36 bottomland forest restoration sites. Densities of thamnic (shrub-scrub dwelling) and silvicolous birds, such as yellow-breasted chat (Icteria virens), indigo bunting (Passerina cyanea), and white-eyed vireo (Vireo griseus) were positively associated with 1) taller trees, 2) greater stem densities, and 3) a greater proportion of forest within the landscape, whereas densities of birds associated with grasslands, such as dickcissel (Spiza americana) and red-winged blackbird (Agelaius phoeniceus), were negatively associated with these variables. Vegetation structure, habitat edge, and temporal effects had greater influence on nest success than did landscape effects. Taller trees, increased density of woody stems, greater vegetation density, and more forest within the landscape were often associated with greater nest success. Nest success of grassland birds was positively related to distance from forest edge but, for thamnic birds, success was greater near edges. Moreover, nest success and estimated fecundity of thamnic species suggested their populations are self-sustaining on forest restoration sites, whereas these sites are likely population sinks for grassland and open-woodland species. We recommend restoration strategies that promote rapid development of dense forest stands within largely forested landscapes to recruit breeding populations of thamnic and silvicolous birds that have reproductive success sufficient to sustain their populations.

Two climatic parameters were examined for this study, temperature and precipitation. An analysis of eight sites with the giant beaver indicates that the species was cold tolerant and lived under colder January and July temperatures than exist at these sites today. At five of the eight sites the model suggests there was a shift in seasonal precipitation from the greatest amount of precipitation taking place during the late summer-fall in the Pleistocene to spring-early summer today.

The corridor concept has had an important bearing on discussions of zoogeography and paved the way for hypotheses about the recolonization of North America by mammalian species from Asia. Alberta-situated along the eastern slopes of the western Cordillera adjacent to the northern Great Plains-was long considered the ideal route for Late Pleistocene migrations into the North American heartland. Yet, a temporal hiatus in the large suite of bone and wood dates from central Alberta indicates that no corridor existed during the full-glacial, from about 22000 to 12000 BP. DNA, isotopic, and other studies of equids, bovids, cervids, ursids, mustelids and others confirm that animals flowed through Alberta, except during full glaciation. The mid-Wisconsinan fauna in Alberta indicates movements from both south and north, reflecting the absence of ice sheets during that interval. Migrations during the Last Glacial Maximum were precluded because the Cordilleran and Laurentide ice masses had coalesced to close the corridor. Finally, with the postglacial reopening of the passage, late-surviving proboscideans, muskoxen, horses, camels and lions-facing imminent extinction-may have formed a northwesterly bound megafaunal vanguard. Simultaneously, a thriving population of moose and wapiti drove southward from Beringia towards the mid-continent.

The hypothesis posits that North American herpetofaunas essentially were taxonomically and geographically stable throughout the Quaternary. Modern biogeographic distribution of species served as an important criterion for primary identification of the majority of fossil herpetofaunal specimens, rendering the Herpetofaunal Stability Hypothesis circular. Apomorphy-based identifications are an important and well-established alternative to the traditional approach, but are used only rarely within the Quaternary paleontology community. Preliminary applications of the apomorphy-based approach reveal that species-level resolution often is not possible for herpetofaunal remains. Lack of species-level resolution may be a consequence of poor documentation of evolutionary morphology for most herpetofaunal species lineages. Development of adequate skeletal collections and the search for apomorphies in the anatomical systems typically preserved in Quaternary deposits will yield meaningful insights into evolutionary morphology, an enhanced appreciation of Quaternary faunal dynamics, and a greater concordance with modern neontological approaches. Maintenance of traditional methods of identification will yield a false perception of clarity, erroneous interpretations of Quaternary faunal dynamics, and may perpetuate misleading data in Quaternary paleontology as well as other fields that rely on those data.

In each of these locations they appear to inhabit refugia formed by post-Pleistocene eustatic sea level rise. Mammoths existed without the presence of humans (Wrangel Island and the Pribolofs), until extinction, or until contemporary with human colonization (Santa Rosa Island). Using a paleoclimate model developed by the senior author (RAB), the paleoenvironmental conditions of these islands are depicted, analyzed, and interpreted. This provided paleoclimatic evidence for the environments of the latest Pleistocene and mid- to late Holocene mammoth populations and their demise.

While a change in size has long been recognized, the rate and timing of diminution recently has become defined better for Southern Plains bison. Questions regarding what force drove the decrease in body size, however, continue to generate new hypotheses and the use of novel methodological approaches. While many variables influence body size, morphological changes in bison historically are attributed to either human hunting or climate change. New data from a sample of metapodials from well-dated Southern Plains localities depict a rapid decrease in body size in the early Holocene with modern size present by 6500 BP. The pattern and rate of evolution on the Southern Plains is compared to existing hypotheses for bison diminution over the Late Quaternary. Bison size on the Southern Plains correlates best with the spread of the C (sub 4) ecosystem between ca. 8000 and 6500 BP. C (sub 4) grasses are less nutritious than the C (sub 3) grasses they replaced and this decrease in nutritional value of the bison's primary food source likely led to the decrease in body size. The properties of C (sub 4) grasses adequately account for the size reduction of Late Quaternary bison.

The fauna is the largest open-environment, non-asphaltic late Pleistocene assemblage known from the American southwest. Located within the northern Peninsular Range physiographic province of southern California, the Diamond and Domenigoni Valleys contain bedded silts and clays intercalated with coarse-grained channel fill representing a braided stream environment. These fluvial sediments, yielding AMS dates from approximately 19 ka to approximately 13 ka, unconformably truncate older silts, clays and an organic black clay at depth. The clay is lacustrine in origin, with AMS dates from approximately 46 ka to approximately 41 ka. Numerous diagnostic vertebrate remains occur in both of these sediment packages. The Diamond Valley Lake local fauna constitutes a valuable source of new data on the relative density and diversity of late Pleistocene species from a geographic area where such data are largely absent. The assemblage differs dramatically in preservation and composition from other late Pleistocene coastal and desert localities in southern California.

These dates span an interval from 21,228 to 12,944 cal BP. When compared to pollen spectra, it is evident that Mammut americanum inhabited spruce (Picea) and black ash (Fraxinus nigra) forest during the Bolling-Allerod (14,700-12,900 cal BP) and early Younger Dryas (12,900-11,650 cal BP) chronozones. Both Mammuthus jeffersonii and Mammuthus primigenius inhabited spruce dominated open-woodland during the Oldest Dryas chronozone, while M. primigenius persisted in a forest of predominantly black ash during the Allerod chronozone. A newly discovered specimen from Lincoln, IL, clarifies the taxonomic distinction between M. primigenius and M. jeffersonii. Hitherto, a paradigm of proboscidean succession during the full- to late-glacial periods was based on the vegetation succession of steppe tundra-like vegetation to spruce forest to spruce-deciduous forest. The presumed proboscidean succession was that of cold, dry steppe-adapted M. primigenius succeeded by more mesic-tolerant M. jeffersonii that in turn was succeeded by the wet forest-adapted M. americanum. Reported data do not support this view and indicate a need for re-evaluation of assumptions of proboscidean ecology and history, e.g., the environmental tolerances and habits of M. primigenius in regions south of 55 degrees N, and its dynamic relationship with other proboscidean taxa.

We analyzed the isotopes of carbon, oxygen and strontium in 84 specimens of rabbits and marmots to infer (1) if feeding and habitat preferences differed across glacial-interglacial transitions, and (2) whether these taxa responded similarly and synchronously to climatic events. Our results showed no significant differences in any of the isotopic values within taxa across levels. Stable carbon isotope values revealed a C (sub 3) -dominated environment around Porcupine Cave during the middle Pleistocene, similar to what is present around the cave today. Oxygen isotopes did not change significantly across levels suggesting consistent water sources over time and preventing any correlation to the Marine Isotope Stages. Marmots did show significantly more positive oxygen isotope values than rabbits over most of the Pit levels likely indicative of hibernation. Lack of significant change in Sr isotopes indicates similarity in habitat range through time, or homogenization of landscape Sr values due to atmospheric inputs. These results suggest that middle Pleistocene climatic change had a negligible effect on the ecology of the sampled individuals around Porcupine Cave. The effects of climate on mammals are complex and these results cannot be extrapolated globally; research is needed to differentiate how global climate change affects mammals in different regions and of different life history to provide insight into how current global warming will affect extant species.

W. Hibbard for a fossil assemblage recovered from silty clays beneath the "Pearlette" volcanic ash at the type Cudahy ash pit and other sites in Meade County, Kansas. The "Pearlette" ash comprises several variously dated Yellowstone ashes. The Cudahy (=Lava Creek B) ash is most recently dated at 0.639+ or -0.002 Ma and is an important geochronologic marker in the Great Plains. The term Cudahy Ash Pit local fauna is now used for that of the type locality, although other Cudahy-type (Cudahyan) local faunas have been described. From 1968 to 1971, 30 tons of silty clay and diatomite were collected from below outcrops of Lava Creek B ash at elevations of 988-1058 m (3240-3470 ft) in the High Plains of the Texas Panhandle. Screenwashing yielded about 30 mammal taxa and numerous small amphibians, reptiles, birds, and mollusks. Four local faunas (Woody Draw, Bull Draw, Deadman's Creek, and Mayfield Ranch) are recognized. These faunas, dominated by shrews and microtine (arvicoline) rodents, are compositionally similar to each other and to the Cudahy and Sunbrite ash pit local faunas of Meade County even though the Panhandle sites are 300-340 km (186-211 miles) southwest of the Kansas sites and are 213-280 m (700-920 ft) higher in elevation. The Panhandle faunas contain two new species of Sorex as well as Sorex cf. cinereus, Sorex cudahyensis, Sorex lacustris, Sorex (Microsorex) pratensis, Sorex megapalustris, Blarina, Cynomys, Spermophilus, Geomys tobinensis, Thomomys cf. talpoides, Peromyscus cragini, Reithrodontomys moorei, Ondatra annectens, Mictomys meltoni, Microtus llanensis (rare), Microtus paroperarius, and Microtus meadensis. The large sample size of the latter two taxa permits statistical comparisons of teeth with those from Kansas. The Texas faunas further substantiate the Cudahyan as a subage of the Irvingtonian between the older Sappan and younger Sheridanian subages and equivalent to Irvingtonian II based on microtine (arvicoline) rodents. Local habitats consisted of ponds or playas with marshy areas suitable for shrews, muskrats, and bog lemmings. Moist grassy meadows nearby would have been inhabited by voles, mice, and some of the shrews; the less abundant gophers, ground squirrels, and prairie dog would have preferred drier, grassy uplands with well-drained soils. Several mammals (e.g. bog lemming) show affinities with extant boreal species that range through Canada and the northern United States The collective evidence suggests that the Texas Panhandle enjoyed cooler summers with more effective rainfall during Cudahy time.

The dates deemed to be most reliable are on purified collagen samples, and these serve as the basis for interpreting the late Pleistocene chronology and extinction of the species. The oldest acceptable radiocarbon date from the lower forty-eight states is 34,080+ or -480 BP from Island Ford Cave, Virginia, and the youngest is the previously reported 9630+ or -60 BP date from Bonner Springs, Kansas. An additional date of 10,921+ or -50 BP on the same Kansas specimen indicates a precision problem in the age of this individual. Regardless of this anomaly, new AMS dates of approximately 10,800-11,000 BP on A. simus confirm that it existed up to the Pleistocene/Holocene transition and may have been one of the last megafaunal species to go extinct in North America. Further, these dates solidify the co-existence of these massive bears with humans of the Clovis cultural complex.

These sites document nonanalog or disharmonious faunas, recording the association of certain genera or species that are no longer sympatric, in particular taxa now restricted to drier habitats in western North America or tropical habitats in Middle America occurring together with species still found in Florida and the southeastern United States. Extralimital or extinct taxa of western origin in Florida Plio-Pleistocene nonanalog faunas include: the mammals Antrozous, Lepus, Spermophilus, Thomomys, and Baiomys; and the birds Gymnogyps californianus, Teratornis merriami, Aquila chrysaetos, Tympanuchus cupido, two species of Glaucidium, and Pica pica. A large influx of tropical species occurred in Florida late Blancan and early Irvingtonian sites, primarily consisting of taxa of South American origin involved in the Great American Biotic Interchange. Besides large Interchange mammals, other mammals with tropical affinities now extinct or extralimital to Florida include: the bats Desmodus archaeodaptes, Desmodus stocki, Mormoops megalophylla, Pteronotus pristinus, and Eumops underwoodi, the carnivores Leopardus pardalis, Leopardus wiedii, Panthera onca, two species of Conepatus, and Tremarctos floridanus, and the peccary Pecari. Tropical birds in Florida Plio-Pleistocene faunas include the extralimital Tachybaptus dominicus, Laterallus exilis, Jacana spinosa, Buteogallus urubitinga, Milvago chimachima, Vanellus chilensis, and Ceryle torquata; as well as several extinct species including Titanis walleri, a chachalaca (Family Cracidae), Amplibuteo concordatus, Spizaetus grinnelli, and Cremaster tytthus. These tropical and western taxa indicate the presence of biogeographic corridors during Plio-Pleistocene glacial intervals that connected the Florida peninsula to both the arid western United States and tropical Middle America. A mosaic of desert grassland and savanna habitats intermixed with wetlands apparently extended eastward from the arid Southwest through Texas and along a southeastern corridor to the Florida peninsula. A Gulf Coast savanna corridor supporting savanna and thorn scrub habitats probably existed during glacial low sea level stands on the exposed continental shelf and coastal plain along the northern margin of the Gulf of Mexico, connecting the Florida peninsula with Mexico and Central America. The occurrence of both tropical and western taxa in some of the same faunas strongly indicates that these distributional patterns were contemporaneous and corresponded to climatic conditions and vegetational associations that no longer exist in Florida.

This work evaluated 138 published radiocarbon dates for megafauna and 402 published dates for early (>8000 BP) South American archaeological sites. A total of 93 megafauna dates for 15 genera, and 110 archaeological dates on early human appearance, are robust enough to assess correspondence between last-appearance records of megafauna, first-appearance records of humans, and the Younger Dryas to Holocene climatic transition in six different regions of South America. Interesting patterns come to light, but are based on few dates, particularly in northern South America. No taxon other than Mylodon has >7 robust dates, and many taxa have less than 3 dates. Accordingly, an assessment of how likely it is that only a few dates will yield the youngest date in an underlying frequency distribution of dates was conducted, by applying probability and bootstrapping analyses to 27 dates on Mylodon from southern Patagonia, 26 of them from a single site. It was found that 15 dates out of a sample of 27 will commonly yield a date within 200 years of the youngest date in the sample. For that reason, and because even for a taxon with many dates it is likely that the youngest dated specimen pre-dates the actual time of extinction, most of the last-appearance dates are interpreted as recording the last time taxa were abundant on the landscape, rather than extinction per se. With those caveats in mind, on a continental scale most megafauna have last appearances after human arrival, but seem to last at least 1000 years after first human presence. Some taxa apparently survived >6000 years after humans entered South America and >1000 years after the end-Pleistocene climatic changes. Last-appearance patterns for megafauna differ from region to region, but in Patagonia, the Argentine and Uruguayan Pampas, and Brazil, extinctions seem more common after humans arrive and during intensified climatic change between 11.2 and 13.5 ka. This pattern suggests that a synergy of human impacts and rapid climate change-analogous to what is happening today-may enhance extinction probability. Nevertheless, even in these regions, some megafauna persisted for thousands of years after human arrival and after the climate warmed. These results highlight the need for future intensive dating efforts on South American megafauna and archaeological remains.

It has been proposed that this richness was achieved by paleoenvironments that permitted both the immigration and intermingling of boreal, steppe, and sub-tropical taxa with the present day deciduous forest micromammal community. Contemporaneity of component taxa cannot be assumed without (super 14) C dating because taphonomic processes can produce similar configurations. If 'non-analog' specimens are contemporaneous, they represent communities with no modern analogs. If the dates on component species are disjunct, they are an artifact of time averaging and the species have a different paleoecological significance. The question remains: What is a significant interval of time to assert a community versus a time-averaging interpretation for Pleistocene faunal configurations? Analysis of 132 AMS (super 14) C dates from 21 caves in southeastern North America (Fig. 1) on 16 presently allopatric or marginally sympatric (distantly) micromammal taxa demonstrate that these species are contemporaneous in many deposits. While other sites produced non-analog associations because of taphonomic processes, dates on many component specimens are contemporaneous regionally. The regional, as well as local, non-analog associations documented here demonstrate that a widespread, non-analog micromammal community occupied southeastern North America during the last glacial. These species-rich, non-analog communities, which contrast sharply to the species-depauperate Holocene faunas, probably were supported by unique but chronologically and geographically variable last-glacial environments. Although the AMS dates are not evenly distributed chronologically and radiocarbon plateaus occasionally exert influence, late Wisconsinan, non-analog communities of variable composition were present and likely influenced by Heinrich events. Other factors, some not yet identified, undoubtedly contributed to community structures.

At least 70 vertebrate taxa are identified in this local fauna including fish, four lissamphibians, six sauropsids, eight birds, and fifty-one mammal species. A largely granitic structural dome, the Llano uplift differs from the rest of the predominantly carbonate Edwards Plateau in geology, soils and ecology. This is reflected in the Zesch Cave local fauna as well, which has greater similarity to high plains faunas than those recorded 80 km or more to the south. Notably, this local fauna contains the first record of Sorex hoyi (pygmy shrew) and Pica pica (magpie) from central Texas, which indicates similarity or connection with a Rocky Mountain fauna. The Zesch Cave vertebrates provide a more complete picture of faunal zones as they existed in the Rancholabrean.

Earliest members are recorded from the late Blancan Land Mammal age, Late Pliocene. The fossil history for Cynomys is well reconstructed for the Great Plains of the USA and Canada. However, it is insufficiently studied for the arid Southwest and almost entirely unknown for adjacent northern Mexico. This paper reports on the remains of Cynomys recovered from the paleontological site of La Playa, northern Sonora, Mexico. Two species of Cynomys live today in Mexico in disjunct, likely relictual locations, Cynomys ludovicianus and Cynomys mexicanus. The distribution of prairie dogs today does not include the region of La Playa: the closest population lives about 150 km north and east in northeastern-most Sonora and adjacent Arizona. The identification criteria presented here indicate that the black-tailed prairie dog, C. ludovicianus, inhabited the valley bottom now exposed as the La Playa fossil deposits. The description of this species from La Playa represents the first report of Rancholabrean prairie dogs from Sonora. Its recovery from the extremely low elevations of northern Sonora indicates that a different climatic regime was in operation during the Late Pleistocene resulting in local vegetation and soil types considerably different from those recorded there today. The late Wisconsinan Glacial climate supported herbivores that cannot inhabit the area today.

To explore this issue, late Pleistocene species representation in cave versus non-cave deposits was examined. Additionally, this study examined how fossiliferous cave deposits influence perceptions of past biogeographic distributions, and evaluated factors that impact the distribution of cave deposits. Across the United States, cave deposits account for a high proportion of the individual species records known from the late Pleistocene and caves provide the only late Pleistocene records of 14 individual taxa. Calculated ratios of individual taxonomic records from caves relative to the total number of individual taxonomic records resulted in a value of 0.62. The impact of cave data on understanding of late Pleistocene biogeographic distribution patterns vary among individual species of sciurid rodents. Geographic analyses comparing the distribution of cave and non-cave sites in Texas suggest a strong relationship between site distribution and specific geologic and hydrologic features. Ultimately, understanding potential biases recorded in distinct depositional settings provides improved frameworks for interpreting the adequacy of the fossil record.

A key assumption common to all these scenarios is that large mammals present in North America near the end of the Pleistocene were also present in similar abundance, with similar geographic distributions, during earlier, equally severe periods of climate change (e.g., approximately 130 ka BP). This assumption is challenged here. An important difference in the latest Pleistocene was the profusion and geographic extent of the genus Bison, particularly in the American West. During the late Pleistocene, south of the glacial ice, the species Bison antiquus was more widely distributed and present in greater profusion than earlier species such as the larger B. latifrons. The increased abundance of these large, aggressive, herd-dwelling ruminants in the late Pleistocene constitutes a critical difference between this time period and earlier, similarly intense interglacials. Extinction scenarios for Pleistocene North America should avoid assuming a relatively static long-term faunal component, and account for the impacts of non-human immigrant species on natives, particularly when immigration events are close in time and space with climate changes.

Post-Pleistocene extinction chiefly involved meso- and megabaric species. The mammal, palynologic and paleosol records are strongly time and space biased in favor of Late Rancholabrean data from a few morphotectonic provinces; hence, only broad climatic trends could be delineated, which approximately coincide with those known for the Wisconsinan; they disclose by 25-12 ka, greater moisture and cooler temperature conditions than at present, coinciding too with a larger mammalian diversity and local faunas disharmony. Climate fluctuations impacted the fauna, causing species distribution changes and extinctions. The Recent fauna's complex biogeographic pattern reflects this; it includes tropical and temperate species associations outside their respective latitudes. Combining geologic and Recent mammal distribution data with the Pleistocene record, possible dispersal routes were detected: high and low land, southward corridors for temperate species, and low land, northward ones for tropical species. Finally, the existence of a single Mexican Rancholabrean Faunal Province is incompatible with mammal record's makeup and distribution, which calls for a multiprovince scheme to better understand Mexico's Pleistocene mammal biogeography and faunistics.

Evidence that staging cranes acquired less lipid reserves during the 1990s compared to the late 1970s and increases in use of the CPRV by snow geese (Chen caerulescens) prompted us to investigate availability of waste corn and quantify spatial and temporal patterns of crane and waterfowl use of the region. We developed a predictive model to assess impacts of changes in availability of corn and snow goose abundance under past, present, and potential future conditions. Over a hypothetical 60-day staging period, predicted energy demand of cranes and waterfowl increased 87% between the late 1970s and 1998-2007, primarily because peak abundances of snow geese increased by 650,000 and cranes by 110,000. Compared to spring 1979, corn available when cranes arrived was 20% less in 1998 and 68% less in 1999; consequently, the area of cornfields required to meet crane needs increased from 14,464ha in 1979 to 32,751ha in 1998 and 90,559ha in 1999. Using a pooled estimate of 88kg/ha from springs 1998-1999 and 2005-2007, the area of cornfields needed to supply food requirements of cranes and waterfowl increased to 65,587ha and was greatest in the eastern region of the CPRV, where an estimated 54% of cranes, 47% of Canada geese (Branta canadensis), 45% of greater white-fronted geese (Anser albifrons), and 46% of snow geese occurred during ground surveys. We estimated that a future reduction of 25% in available corn or cornfields would increase daily foraging flight distances of cranes by 27-38%. Crane use and ability of cranes to store lipid reserves in the CPRV could be reduced substantially if flight distance required to locate adequate corn exceeded a physiological maximum distance cranes could fly in search of food. Options to increase carrying capacity for cranes include increasing accessibility of cornfields by restoring degraded river channels to disperse roosting cranes and increasing wetland availability in the Rainwater Basin to attract snow geese using the CPRV.

Earlier in the 20th century, land cover was on a trajectory of forest expansion that followed agricultural abandonment. However, the potential for forest regeneration has slowed, and the extent of regional forest cover has declined by more than 4.0%. Using remote-sensing data, statistical sampling, and change-detection methods, this research shows how land conversion varies spatially and temporally across the East from 1973-2000, and how those changes affect regional land-change dynamics. The analysis shows that agricultural land use has continued to decline, and that this enables forest recovery; however, an important land-cover transition has occurred, from a mode of regional forest-cover gain to one of forest-cover loss caused by timber cutting cycles, urbanization, and other land-use demands.

To establish a less onerous, yet accurate method, for determining emergent plant biomass than by direct measurements we collected vegetation data over a six-year period and modeled biomass using easily obtained variables: culm (stem) diameter, culm height and culm density. From 1998 through 2005, we collected emergent vegetation samples (Schoenoplectus catifornicus and Schoenoplectus aculus) at a constructed treatment wetland in San Jacinto, California during spring and fall. Various statistical models were run on the data to determine the strongest relationships. We found that the nonlinear relationship: CB = ( beta sub(0)DH super( beta )10, where CB was dry culm biomass (g m super(-2)), DH was density of culms x average height of culms in a plot and beta sub(0) and beta sub(1) were parameters to estimate, proved to be the best fit for predicting dried-live above-ground biomass of the two Schoenoplectus species. The random error distribution, epsilon , was either assumed to be normally distributed for mean regression estimates or assumed to be an unspecified continuous distribution for quantile regression estimates.

Early reports suggested that increased moisture improved tree growth and mast production; however, recent reports showed reduced vigor and growth. This study examines the effects of 20 years of GTR management practices in the Felsenthal National Wildlife Refuge, Crossett, Arkansas. Tree species composition, size characteristics, and vigor classes were measured in 1990, 1995, 2001, and 2006. The overall annual tree mortality rate was 2.6%, with high elevations at 1.7% and low elevations at 3.1%. Annual mortality rates exceeded 3% for willow oak (Quercus phellos) and water hickory (Carya aquatica), while rates for Nutlall oak (Q. texana), overeup oak (Q. lyrata), and sweetgum (Liqutdambar styraciflua) were lower at 2.8, 2.4, and 1.5%, respectively. Tree health (vigor) has degraded substantially for over 60% of trees initially rated in good or fair condition. Statistical probit models were generated to predict short-term (5 years) and long-term (15 years) vigor degradation. Low numbers of saplings and little advanced regeneration indicated lack of tree replacement, suggesting that inundation strategies of the GTR management may have long-term impacts on forest structure and composition in the southeastern United States.

We used data from point-count surveys collected across North America over eight years to evaluate the extent to which each of 13 local marsh bird species responded to conspecifie and heterospecific call-broadcast relative to passive survey methods. Surveyors detected more individuals during the 1-mtnute of conspecific call-broadcast compared to each of the five 1-minute passive segments and all of the 1-minute heterospecific call-broadcast segments tor all species. Surveyors also detected more individuals during most of the 1-minute heterospeciic call-broadcast segments compared to the 1-mimne passive segments. Most birds responded to conspecific call-broadcast quickly (within 1 min), but we found some evidence for a lag time in birds' response to conspecific calls. The percent increase in the number of birds detected as a result of conspecific call-broadcast (relative to passive survey methods) varied between 14% (American bitterns ([Botaurus lentiginosus]) to 632% (purple gallinules [Porphyrula martinica]). We recommend the use of point-count surveys thai include both passive and call-broadcast segments for numerous marsh birds when collecting data to assess occupancy, evaluate the effects of wetland management practices, and estimate population trends of marsh birds.

Numerous springs issue from a trans-boundary aquifer in the area. We have initiated structural and geochemical studies of the springs to elucidate recharge areas, groundwater flow paths to the springs, the effects of regional structure, and the influence that the springs have on water quality and quantity in the Rio Grande. Groundwater in the LC is represented by the Cretaceous Edwards-Trinity Plateau Aquifer (ET). International Boundary and Water Commission (IBWC) gage data indicate that base flow progressively increases by as much as 60% due to spring inflow in the LC. Base flow data from these gages in 2004 suggests spring input at 178,000 acre feet/year. Data from the winter 2006 USGS/NPS seepage run indicates 108,595 to 144,793 acre feet/year. Ground water input is also responsible for dilution of total dissolved solids (TDS) in the Rio Grande. Major element variations reveal two groups of springs, one with an average of 533 mg/L TDS which plots on a Piper diagram as a Na-SO (sub 4) type of water and a second set with an average of 282 mg/L TDS that plots as a Ca-HCO (sub 3) type water. The two spring groups plot in distinct areas on a graph of d (super 18) O versus d-D. The Na-SO (sub 4) waters originate near a local meteoric water line (MWL) ranging from dD approximately -53 to -48 per mil and d (super 18) O approximately -7 to -3 per mil. The Ca-HCO (sub 3) waters plot with higher dD and d (super 18) O values, approximately on the MWL. Local groundwater northwest of the Ca-HCO (sub 3) waters also plot in this location. Our mapping of the structures in the LC show northwest trending joints and fold axes. GIS analysis of the water chemistry reveals that the Na-SO (sub 4) waters are located south and west of a major northwest trending structure represented by the Bullis Fold and the Ca-HCO (sub 3) waters are located north and east of this structure. Variations in the Na-SO (sub 4) waters could be the result of a longer residence time and possible communication with Paleozioc sedimentary rocks in the Marathon Basin, which are located approximately 30 km to the northwest, beyond the mapped extent of the ET aquifer. Alternatively, the Ca-HCO (sub 3) waters may be associated with recent meteoric recharge directly into the ET aquifer.

The participating students were selected from various backgrounds based upon their ability to contribute to the project, which was designed to assist an ongoing project in BBNP to monitor the status of a selected set of sand bars in the canyon. Specific content areas included GIS/GPS mapping, biology, hydrology of the Rio Grande, geology of the Big Bend region, and the archeology and recent history of the canyon and the Rio Grande. The hydrology and biology of the river canyons in BBNP have become degraded over the past century as the result of prolonged low flow conditions caused by up-stream diversions and by the gradual appearance of invasive species such as giant river cane (Arundo donax) and tamarisk (Tamarisk spp., salt cedar). A feed back mechanism between dense stands of exotic vegetation and trapped sediment has transformed the river channel from a wide, mobile, meandering multi-threaded system with little riparian vegetation to a constrained, deeper single channel bound on one or both sides by high, stable sand bars fortified by dense groves of tamarisk and/or river cane. This shift includes a degradation of the aquatic habitat in the channel itself, along with the obvious degradation of the hydrology of the channel sand bar system. The project involved the use of canoes and survey equipment to conduct a 4 day float trip through Boquillas canyon with the specific goal of completing a series of topographic surveys of sand bars that have been the focus of previous similar surveys. One primary goal was to compare the survey results to previous surveys and to construct channel cross sections for hydrological modeling. The students were directly involved in the survey work. Additionally, informal lectures included discussions of career development, geology, biology, archeology and hydrology. The results of the surveying included the observation of significant changes in the morphology and vegetation on the sand bars due to the flooding that occurred in the Fall of 2008. Additionally, the work contributed to a base line of information for comparison in future efforts.

The ichnofossils are preserved at the top of a sheet sandstone in the Orella Member of the Brule Formation (White River Group, Oligocene). We interpret the best preserved tracks as those of the medium size rhinoceros Subhyracodon. Tracks of other members of the White River body fossil fauna are also recognized, including Mesohippus, entelodonts, oreodonts, birds and invertebrates. Three-dimensional photogrammetric documentation is being used facilitate ichnological and paleoecological study of the trackways, as large trackways like this one are vulnerable to rapid destruction by weathering, foot traffic and vandalism but nearly impossible to collect. Photogrammetric products like millimeter-resolution digital terrain models provide accurate reproduction of details, are easier to manipulate than both the original tracks in the outcrop and molds or casts made from them and they can be distributed widely to multiple researchers. Methods adapted from remote sensing and geographic information systems to the analysis of digital trackway data can be used to quantify track geometry and enhance visual observation of ichnological information.

This involves documenting the features, issues and processes specific to that park and to make a "crosswalk" between a digital geologic map and these features, issues and processes. Numerous steps are involved in completing a park's GRE including conducting scoping meetings, assembling geologic bibliographies of all known applicable references, producing digital geologic maps (bedrock, surficial, abandoned mines, caves, coastal features, etc.), and then assembling all of this information into a usable database. Many cooperators are active in the entire process (federal, state, academic, private etc.)and contribute at various levels from educating park management on geologic resource issues to actually producing geologic field maps. The end result of this multi-faceted cooperation is better stewardship of geologic resources in NPS areas for the enjoyment of future generations.

National Park Service ER - TY - JOUR T1 - Water quality monitoring at Great Plains national parks AN - 756291864; 2010-082912 AB - Northern Great Plains Network (NGPN), as part of the National Park Service's (NPS) Inventory & Monitoring Program, is measuring status and trends of core water quality parameters in NPS units in the Dakotas, eastern Wyoming and Nebraska. To accomplish this objective we must optimize efficiency, effectiveness, and quality of inference from this monitoring effort while considering budget constraints. The impact of multiple sources of variation regarding statistical power analyses must be considered. We need to take into account the impact that within-park spatial variation as well as systematic and random diurnal, seasonal, and yearly temporal variation have on statistical precision and power. For this effort we are examining pilot and historic data to address 3 key questions. First, for which parks is spatial variability in core parameters minimal so that one monitoring site (or group of subsites) is adequate for representing the river/stream reaches of interest? Examination of pilot data indicate that for NGPN parks with relatively short stretches of rivers, one monitoring site per park will represent core parameters adequately. In addition, pilot data suggest that widely separated sites in a park show similar values in water temperature, pH, and dissolved oxygen. However, data indicate higher spatial variability for conductivity. Additional pilot data will be collected to refine estimates of spatial variation at the parks. Second, regarding expected variability at diurnal, weekly, and monthly scales within a season, is monitoring effort best focused on repeated field visits to periodically measure core parameters or on deployment of continuous monitors to collect measurement throughout the season? Pilot data from continuous probes deployed at 10 locations during 2008-2009 are being used to compare expected accuracy between periodic field visits and continuous monitoring. Third, what effect do alternative sampling strategies and revisit intervals have on our expected power to assess water quality trends at each park? To address this question, we are examining long-term historic data (10+ years) to quantify variation in core parameters for select rivers/streams.

Knight of UW and James Kemp of Columbia University. These renowned geologists built the summer field program into one of national acclaim by utilizing Wyoming's unique geological resources to teach important concepts. Today, UW's field camp continues to attract students from around the country, exposing them to the wonders of western geology in Wyoming and neighboring states. Over the past decade, the class has successfully utilized world-class paleontological field sites under active study by UW students and staff. This holistic, hands-on approach weaves together paleontology, sedimentology and stratigraphy, as well as public outreach and resource management practice. Two unique ichnological sites have been utilized in class activities. The Middle Jurassic Red Gulch Dinosaur Tracksite in the Bighorn Basin of northern Wyoming and the Late Jurassic Seminoe Reservoir Tracksite in central Wyoming are managed (by the Bureau of Land Management and Bureau of Reclamation respectively) and preserved for current and future generations. Although most paleontological sites are unavailable for public visitation, public land sites such as these can be unique educational tools. Student activities at these sites range from scientific documentation and interpretation to management and protection discussions, exposing students to concepts of resource protection through resource education and allowing greater appreciation of public lands and resources. Working in small groups, summer camp participants make observations, collect data, and develop their own interpretations regarding the geologic history of particular localities. Importantly, researchers actively working at the sites visited with the field program's students to walk them thought the actual process of investigation, interpretation, and management. Thus, students were exposed to both traditional (e.g., on the ground measuring and mapping) and state-of-the art documentation technologies (e.g., photogrammetry) and learned where research observations interface with research interpretations.

Here in a 1,000 m (super 2) slickrock area of the Navajo Formation (age approximately 185 ma) multiple track levels are revealed. This spectacular vertebrate paleontological resource lies in a very popular off-highway vehicle (OHV) area. The Moccasin Mountain Tracksite (MMT) provides an ideal opportunity for the successful synergy of management, science, technology, interpretation, and recreation. OHV activity has impacted the track surface at the MMT necessitating the closure of the track-bearing area to vehicular traffic to protect this significant paleontological resource. Scientifically, the site contains a high ichno-diversity and density, with important preservational features. At least six different track types have been observed, including tridactyl (Grallator and Eubrontes) and tetradactyl forms (Batrachopus and Otozoum). Tracks occur on dune foreset beds, interdune-bounding, and truncation surfaces, and are preserved as underprints and molds, in convex hyporelief, and more rarely in concave epirelief. The morphology varies from distinct preservation of anatomical features, such as pads and claw impressions, to areas of undifferentiated dinoturbation. In 2008, close-range photogrammetric documentation of the site was conducted using both ground-based and low-altitude aerial imagery. Digital terrain data and ortho-imagery, at a variety of scales, are integrated into a unified real-world coordinate system for display and analysis in a Geographic Information System. The proximity of the site to recreational destinations in Southern Utah and its unique scientific value make it ideally suited for a BLM "Take It Outside" program. This Program encourages children and their families to spend more time outdoors on the public lands; to improve children's overall health; and to promote stewardship of the public lands. The integrated imagery forms the basis for a brochure for K- 12 students, and adults, to use as a self-guided tour of the site. This brochure will be an effective tool for interpreting this unique site to the public and increasing awareness and concern for such natural treasures.

The first, Archaeotherium mortoni, was described by Joseph Leidy in 1850 and is one of the first fossils described in North America from west of the Mississippi. Entelodonts are widely recognized as suiform artiodactys with distinct pendulous flanges developed from the jugal bone and at least one, but normally two, pairs of knob-like tubercles on the dependent margin of the mandibular ramus. Both of these derived features served a primary function of supporting a modified musculature that facilitated large gape. In the cases of extreme derivation, which is seen in ontogenetically older larger specimens, the flanges and tubercles had a secondary display function. Entelodonts display strong size dimorphism as well as ontogenetic variation. The jugal flanges and mandibular tubercles continued to modify, and in some cases enlarge, throughout the life of the animal. Thus, it is nearly impossible to find two identical skulls. The wide range of morphological variation has made it difficult to diagnose species within the family. The result has been that 56 species of entelodont have been described in the past 150 years, nearly half of these from the White River formations. Continuing study indicates that there are currently 10 recognizable species of entelodont representing two genera (Archaeotherium and Megachoerus) found in the White River formations of South Dakota. A third genus (Pelonax) is provisionally considered to be synonymous with Megachoerus.

Aggregations of fine sediments are a suitable proxy for the presence and abundance of Tubifex tubifex, one of the obligate hosts in the parasitic life cycle that causes salmonid whirling disease (Myxobolus cerebralis).2. To determine and evaluate practical approaches to predict fine sediments (<2 mm diameter) that could support Tubifex spp. aggregations, we measured habitat features in a catchment with field measures and metrics derived from digital data sets and geospatial tools at three different spatial extents (m2) within a hierarchical structure.3. We used linear mixed models to test plausible candidate models that best explained the presence of fine sediments measured in stream surveys with metrics from several spatial extents.4. The percent slow water habitat measured at the finest extent provided the best model to predict the likely presence of fine sediments. The most influential models to predict fine sediments using landscape metrics measured at broader extents included variables that measure the percentage land cover in conifer or agriculture, specifically, decreases in conifer cover and increases in agriculture.5. The overall best-fitting model of the presence of fine sediments in a stream reach combined variables measured and operating at different spatial extents.6. Landscape features modelled within a hierarchical framework may be useful tools to evaluate and prioritise areas with fine sediments that may be at risk of infection by Myxobolus cerebralis.

Theory predicts that dispersal through multiple pathways can stabilize populations, preventing extinction in habitat networks. However, empirical data to support this prediction are absent for most species, especially those at risk of decline. Our mark-recapture study of stream salamanders reveals both a strong upstream bias in dispersal and a surprisingly high rate of overland dispersal to adjacent headwater streams. This evidence of route-dependent variation in dispersal rates suggests a spatial mechanism for population stability in headwater-stream salamanders. Our results link the movement behavior of stream salamanders to network topology, and they underscore the importance of identifying and protecting critical dispersal pathways when addressing region-wide population declines.

We conducted a case study of 2 Rhizophora mangle habitats in Hawaii, comparing habitat parameters and macrofaunal community structure in introduced mangroves and nearby control sandflats at a similar tidal elevation. Mangrove sediments had finer sediments and higher organic carbon concentrations and porewater salinities than sandflats. Emergent mangrove roots were colonized by the introduced barnacles Chthamalus proteus, Balanus reticulatus, and B. amphitrite and the introduced sponges Suberites zeteki, Sigmadocia caerulea, and Gelloides fibrosa. Higher densities of non-native macrofauna were found in mangrove transects than in sandflat controls, indicating that invasive mangroves facilitate the persistence of non-native fauna in Hawaii. Mangrove habitats also had higher macrofaunal species richness and diversity, as well as greater dominance by subsurface deposit feeders. Introduced mangroves substantially altered benthic community structure, in part by enhancing the structural complexity of the Hawaiian coastal environment. Because macrobenthos provide a variety of ecosystem services, e.g. serving as prey for fish and birds and promoting detrital decomposition, mangrove-induced changes in sediment community composition will likely have far-reaching consequences in Hawaii. Similar consequences of mangrove invasion are likely in other regions, as mangrove habitats expand with climate warming and increased coastal sedimentation.

Introduced mosquito-borne disease, in particular the avian malaria Plasmodium relictum, has been incriminated as a leading cause of extinction during the 20th century and a major limiting factor in the recovery of remaining species populations. Today, most native Hawaiian bird species reach their highest densities and diversity in high elevation (>1,800m above sea level) forests. We determined the thermal requirements for sporogonic development of P. relictum in the natural vector, Culex quinquefasciatus, and assessed the current distribution of native bird species in light of this information. Sporogonic development was completed at constant laboratory and mean field temperatures between 30 and 17C, but development, prevalence, and intensity decreased significantly below 21C. Using a degree-day (DD) model, we estimated a minimum threshold temperature of 12.97C and a thermal requirement of 86.2 DD as necessary to complete development. Predicted (adiabatic lapse-rate) and observed summer threshold isotherm (13C) correspond to the elevation of high forest refuges on the islands of Maui and Hawai'i. Our data support the hypothesis that avian malaria currently restricts the altitudinal distribution of Hawaiian honeycreeper populations and provide an ecological explanation for the absence of disease at high elevation.

Prevalence values were tested for correlation with a large number of environmental variables, as modeled from weather station data and measured by satellite-borne sensors. Predictions were made based on the expected effects of climatic and landscape variables on sustained populations of arthropod vectors required for transmission of microfilariae. In general, findings were consistent with predictions in both cormorants and penguins; prevalence correlated positively with temperature, precipitation, and vegetation density, and negatively with measures of environmental variability. Resulting correlates were used to derive predictive distributions of prevalence values in cormorants throughout the archipelago. Evidence is presented implicating the mosquito Aedes taeniorhynchus as a likely vector. Knowledge of environmental variables that predict risk of disease transmission by arthropod vectors may be useful in control measures should novel pathogens be introduced to the ecosystem.

Analysis of molecular variance, genetic distance measures, and cluster analysis were used to examine the diversity, gene flow, and relatedness among the samples. The diversity estimates for the samples from Isle Royale were similar to those for the samples collected from Minnesota tributaries of Lake Superior, and all estimates were lower than those reported in other studies of brook trout from eastern North America. Genetic differences were detected among the brook trout at Isle Royale, Lake Nipigon, and the Minnesota tributaries of Lake Superior. Further, the population in Tobin Harbor at the eastern end of Isle Royale was distinct from the populations from tributaries at the southwestern end of the island. The Minnesota tributary population formed a group that was genetically distinct from those from Isle Royale and Lake Nipigon. The Isle Royale population should be managed to preserve the genetic and phenotypic variation that distinguishes it from the other brook trout populations analyzed to date.

We developed and employed PIT tag antenna wand techniques in two controlled experiments and an additional case study to examine the factors that influenced our ability to estimate population size. We used Pollock's robust-design capture-mark-recapture model to obtain estimates of the probability of first detection (p), the probability of redetection (c), and abundance (N) in the two controlled experiments. First, we conducted an experiment in which tags were hidden in fixed locations. Although p and c varied among the three observers and among the three passes that each observer conducted, the estimates of N were identical to the true values and did not vary among observers. In the second experiment using free-swimming tagged fish, p and c varied among passes and time of day. Additionally, estimates of N varied between day and night and among age-classes but were within 10% of the true population size. In the case study, we used the Cormack-Jolly-Seber model to examine the variation in p, and we compared counts of tagged fish found with the antenna wand with counts collected via electrofishing. In that study, we found that although p varied for age-classes, sample dates, and time of day, antenna and electrofishing estimates of N were similar, indicating that population size can be reliably estimated via PIT tag antenna wands. However, factors such as the observer, time of day, age of fish, and stream discharge can influence the initial and subsequent detection probabilities.

AN - 733636096; 19768486 AB - Low levels of agricultural herbicides often contaminate surface water and might persist throughout the growing season, potentially acting as stressors on aquatic organisms. Although low-dose, chronic exposures to agrochemicals are likely common for many nontarget organisms, studies addressing these effects using end-use herbicide formulations are rare. We exposed three common species of tadpoles to conservative levels of atrazine, S-metolachlor, and glyphosate end-use herbicide formulations throughout the larval period to test for survival differences or life-history trait alterations. Exposure to the glyphosate product Roundup WeatherMax at 572 ppb glyphosate acid equivalents (a.e.) resulted in 80% mortality of western chorus frog tadpoles, likely as a result of a unique surfactant formulation. Exposure to WeatherMax or Roundup Original Max at 572 ppb a.e. also lengthened the larval period for American toads. Chronic atrazine and S-metolachlor exposures induced no significant negative effects on survival, mass at metamorphosis, or larval period length at the levels tested. These results highlight the importance of explicitly tying chronic tests to the natural environment and considering contributions of surfactant/adjuvant components to end-use formulation toxicities, even between very similar products.

FGCM deposits consist of sand, silt, clay, and organic matter that accumulate behind large woody debris (LWD) along the margins of the wetted perimeter of the single-thread, gravel-bed South River in Virginia. These deposits store a total mass equivalent to 17% to 43% of the annual suspended sediment load. Radiocarbon, 210Pb and 137C dating indicate that sediment in FGCM deposits ranges in age from 1 to more than 60 years. Reservoir theory suggests an average turnover time of 1.75 years and an annual exchange with the water column of a mass of sediment equivalent to 10% to 25% of the annual sediment load. The distribution of ages in the deposits can be fitted by a power function, suggesting that sediment stored in the deposits has a wide variety of transit times. Most sediment in storage is reworked quickly, but a small portion may remain in place for many decades. The presence of FGCM deposits indicates that suspended sediment is not simply transported downstream in gravel-bed rivers in agricultural watersheds: significant storage can occur over decadal timescales. South River has a history of mercury contamination and identifying sediment sources and sinks is critical for documenting the extent of contamination and for developing remediation plans. FGCM deposits should be considered in future sediment budget and sediment transport modeling studies of gravel-bed rivers in agricultural watersheds.

12971990 AB - New optically stimulated and radiocarbon ages for alluvial fan and lake deposits in the Mojave Desert are presented, which greatly improves the temporal resolution of surface processes. The new Mojave Desert climate-landscape record is particularly detailed for the late Holocene. Evidence from ephemeral lake deposits and landforms indicates times of sustained stream flow during a wet interval of the latter part of the Medieval Warm Period at ca. AD 1290 and during the Little Ice Age at ca. AD 1650. The former lakes postdate megadroughts of the Medieval Warm Period, whereas the latter match the Maunder Minimum of the Little Ice Age. Periods of alluvial fan aggradation across the Mojave Desert are 14-9 cal ka and 6-3 cal ka. This timing largely correlates to times of increased sea-surface temperatures in the Gulf of California and enhanced warm-season monsoons. This correlation suggests that sustained alluvial fan aggradation may be driven by intense summer-season storms. These data suggest that the close proximity of the Mojave Desert to the Pacific Ocean and the Gulf of California promotes a partitioning of landscape-process responses to climate forcings that vary with seasonality of the dominant storms. Cool-season Pacific frontal storms cause river flow, ephemeral lakes, and fan incision, whereas periods of intense warm-season storms cause hillslope erosion and alluvial fan aggradation. The proposed landscape-process partitioning has important implications for hazard mitigation given that climate change may increase sea-surface temperatures in the Gulf of California, which indirectly could increase future alluvial fan aggradation.

13268945 AB - Lead poisoning is a primary factor impeding the survival and recovery of the critically endangered California Condor (Gymnogyps californianus). However, the frequency and magnitude of lead exposure in condors is not well-known in part because most blood lead monitoring occurs biannually, and biannual blood samples capture only 10% of a bird's annual exposure history. We investigated the use of growing feathers from free-flying condors in California to establish a bird's lead exposure history. We show that lead concentration and stable lead isotopic composition analyses of sequential feather sections and concurrently collected blood samples provided a comprehensive history of lead exposure over the 2-4 month period of feather growth. Feather analyses identified exposure events not evident from blood monitoring efforts, and by fitting an empirically derived timeline to actively growing feathers, we were able to estimate the time frame for specific lead exposure events. Our results demonstrate the utility of using sequentially sampled feathers to reconstruct lead exposure history. Since exposure risk in individuals is one determinant of population health, our findings should increase the understanding of population-level effects from lead poisoning in condors; this information may also be helpful for other avian species potentially impacted by lead poisoning.

Twenty-six wintering Le Conte's Sparrows were radiomarked in 1- and 2-year post-burn units, and monitored for similar to 10 days. Additionally, 1-ha plots on each 1-, 2- and 3-year (n = 15) post-burn units were flush-netted once monthly. Telemetry results indicated Le Conte's Sparrows were sedentary during winter with a 50% probability mean home-range of 2.41 ha (72% < 1 ha) and a 95% probability mean home range of 10.31 ha (44% < 1 ha and 55% < 1.5 ha). Home-range size did not differ between post-burn year 1 and 2 (P = 0.227). Le Conte's Sparrows appeared to exhibit a behavioral response to flush-netting (P < 0.001) with estimated capture probability of 0.462 and recapture probability of 0.056. Our findings suggest Le Conte's Sparrows remain fairly sedentary throughout the winter.

We observed 25 events of Common Ravens at or near artificial nests with infertile crane eggs; 15 of those events resulted in predation. Reconnaissance time averaged 1.8 plus or minus 3.0min, egg handling averaged 5.8 plus or minus 3.9min, and total time to reconnoiter, approach, and consume or remove eggs from a nest averaged 8.4 plus or minus 5.7min. Ravens consumed 67% of the eggs at the nest and cached the other 33%. To eat an egg, ravens always punched a hole in the surface, but hole sizes and shapes differed. To cache eggs, ravens carried eggs away intact, leaving no evidence in the nest, and concealed them 5.5 to 180m from the nest. The rapidity of some raven depredation events indicates a high potential for success of taking crane eggs from an active but unattended nests. Given the diverse patterns of eggshell remains and ravens' ability to carry whole eggs, distinguishing egg predation by ravens from other predators would be very difficult.

Lizards have not been reported in the diet of K. sonoriense, and saurophagy is rare in turtles of the United States, having been reported previously in only two other species:, the false map turtle (Graptemys pseudogeographica) and the eastern box turtle (Terrapene carolina). While the diet of K. sonoriense includes snakes, ours is the first record of S. semiannulata as food of this turtle. Ophiophagy also is rare in turtles of the United States with records for only five other species of turtles. Given the opportunistic diets of many North American turtles, including K. sonoriense, the scarcity of published records of saurophagy and ophiophagy likely represents a shortage of observations, not rarity of occurrence.

Thirty sites were selected that differed in their level of watershed development (low to high). An urban intensity value was calculated for each site from 24 landscape variables. Together, these 30 values reppresented a gradient of urban intensity. Among various biological, chemical, and physical factors surveyed at each site, benthic invertebrate assemblages were sampled from stream riffles and also from multiple habitats along the length of the sampling reach. We use some of the NECB data to derive a four-variable urbanintensity index (NECB-UII), where each variable represents a distinct component of urbanization: increasing human presence, expanding infrastructure, landscape development, and riparian vegetation loss. Using the NECB-UII as a characterization of urbanization, we describe how landscape fragmentation occurs with urbanization and how changes in the invertebrate assemblages, represented by metrics of ecological condition, are related to urbanization. Metrics with a strong linear response included EPT taxa richness, percentage richness of non-insect taxa, and pollution-tolerance values. Additionally, we describe how these relations can help in estimating the expected condition of a stream for its level of urbanization, thereby establishing a baseline for evaluating possible affects from specific point-source stressors.

With voluntary reporting by observers, >430 sightings of 154 individually-marked Great Lakes banded birds were documented on the wintering grounds during 1995-2005. This paper reports non-breeding distribution and site-fidelity and identifies Critical Habitat units used by this population during the winter. Information obtained through banded bird sightings indicates that the winter range of Great Lakes Piping Plovers extends from North Carolina to Texas, and the Bahamas, with the majority (75%) of reported individuals wintering in Georgia and Florida. About 95% of sightings were near or within federally-designated winter Critical Habitat for Piping Plovers. Within season (52%) and between-year (62%) site fidelity was documented for resightings within 3.5 km of initial sighting. Although breeding pairs do not winter in close association, there is some evidence to suggest that offspring winter closer to the male rather than the female parent (P-value = 0.03), and adult males and females appear to exhibit latitudinal segregation (P-value < 0.001). Females reach the winter grounds before males, arriving in July and staying through April ( similar to 9 months) or 75% of the annual cycle. The study is the first to identify winter distribution for the Great Lakes Piping Plover population. The significant proportion of the annual cycle spent on the wintering grounds emphasizes the importance of habitat protection during the non-breeding season for this federally-listed population.

Apparent annual survival ( Phi ) is the product of true survival and site fidelity, and estimates of Phi were corrected for the probability of encounter. Overall return rates (individual returned to the study site in a subsequent season) were lower for females (40%) than males (65%), as was Phi ( plus or minus SE, females = 0.65 plus or minus 0.05, males = 0.78 plus or minus 0.03), and encounter rate (females = 0.51 plus or minus 0.07, males = 0.74 plus or minus 0.04). Results differed from previous estimates of Phi for this species as our estimates of Phi were higher for both males and females compared to estimates from another breeding site and two nonbreeding locations. Disparity among Phi estimates from breeding and nonbreeding areas highlights the need to delineate site-specific factors throughout the annual cycle that influence population dynamics of the Western Sandpiper.

One of the three colonies, Pig's Eye, was located near a presumed source of PFCs. Based on a multivariate analysis, the pattern of nine PFC concentrations differed significantly between Pig's Eye and the upriver (P = 0.002) and downriver (P = 0.02) colonies; but not between the upriver and downriver colonies (P = 0.25). Mean concentrations of perfluorooctane sulfonate (PFOS), a major PFC compound, were significantly higher at the Pig's Eye colony (geometric mean = 940 ng/g wet weight) than at upriver (60 ng/g wet weight) and downriver (131 ng/g wet weight) colonies. Perfluorooctane sulfonate concentrations from the Pig's Eye colony are among the highest reported in bird eggs. Concentrations of PFOS in Great Blue Heron eggs from Pig's Eye were well below the toxicity thresholds estimated for Bobwhite Quail (Colinus virginianus) and Mallards (Anas platyrhynchos), but within the toxicity threshold estimated for White Leghorn Chickens (Gallus domesticus). The pattern of six PBDE congener concentrations did not differ among the three colonies (P = 0.08). Total PBDE concentrations, however, were significantly greater (P = 0.03) at Pig's Eye (geometric mean = 142 ng/g wet weight) than the upriver colony (13 ng/g wet weight). Polybrominated diphenyl ether concentrations in two of six Great Blue Heron eggs from the Pig's Eye colony were within levels associated with altered reproductive behavior in American Kestrels (Falco sparverius).

Despite reportedly high rates of early-fall pairing and regional fidelity, both sets of markers indicated that there was little overall genetic structuring by region. Pintails from Suisun Marsh did exhibit higher relatedness among individuals and capture groups than in the Sacramento or San Joaquin Valleys, likely reflecting a sample comprised of a greater proportion of local breeders. The lack of genetic structuring among regions indicates that a high degree of movement and interchange occurs among pintails wintering in the Central Valley. Thus, although maintaining the existing distribution of pintails among Central Valley regions is important for other reasons, it does not appear to be critical to retain current patterns of population genetic variation. Because of potential lack of independence among highly related study individuals, researchers should consider regional differences in relatedness when designing sampling schemes and interpreting research findings.

To prevent breaching in the interim period before a long-term sediment bypassing project could commence, a constructed foredune was emplaced on the island. This foredune was designed using an engineering model to allow occasional overwash, and was placed at a setback distance equal to the expected interim shoreline erosion. Because the design assumptions did not match the actual meteorological and erosional conditions that followed, the foredune proved impenetrable to overwash and disrupted other morphological processes, resulting in undesirable habitat changes. The National Park Service partnered with the U.S. Army Corps of Engineers to address these unintended consequences by restoring the natural geomorphologic processes that create and shape barrier island habitats. Analyzing datasets including island topography, overwash frequency, and meteorological conditions, and revising the assumptions and input data used in the engineering model, the team designed and built multiple pathways through the foredune. These new pathways, which replicate the natural overwash topography found elsewhere on the island, functioned as hoped during recent storms, allowing creation of new overwash fans and build-up of the interior island elevation. Habitat response will be quantified over the coming year to evaluate the biological effects of restoring geomorphic processes, and will guide decisions on whether additional management action is necessary.

Congaree National Park protects >26,000 acres of forested floodplain along the Congaree River. The Congaree Observation Well Network (COWN) includes ten piezometers screened 4-7 m deep and installed along a 1.9 km transect near the northern floodplain margin. This surficial aquifer, which sits on a deep Cretaceous aquifer, consists of a basal sand overlain by a variable top-stratum of peat, clay and sand. The COWN is intended to evaluate the evolution and dynamics of surface and groundwater interactions within the floodplain. In June 2009, ten COWN groundwater samples and two related surface water samples were collected. Field measurements included temperature, conductivity, dissolved oxygen (DO), and pH. Lab analyses included major inorganic ions, alkalinity, dissolved organic carbon (DOC), total dissolved nitrogen (TDN) and dissolved organic nitrogen (DON). All samples were dilute, with ionic strengths 10 mg C/L) than in groundwater (4 mg. These data provide an initial snapshot of the groundwater and surface water geochemistry at this site. They pose many questions about groundwater source, age, and flow paths as well as questions about land use impacts and lacustrine ecology, particularly in light of some distinct differences in the concentrations and speciation of C and N between the groundwater and surface water samples. This collaborative effort is the beginning of an ongoing project to develop a conceptual model of the water balance and groundwater-surface water dynamics of this floodplain forested system.

In certain situations, such as meteorological inversions, human populations can be directly impacted by coal fire emissions. This study presents organic and inorganic gas compositional data from three subbituminous coal bed fires in the Powder River basin of Wyoming, three bituminous coal fires in eastern Kentucky, and a burning bituminous coal waste pile in northern Alabama. Gas composition and temperature varies dramatically between vents at the same fire and among the sites. For example, benzene concentrations ranged five orders of magnitude (0.0008-29 ppmv) and in some cases exceeded human exposure limits (0.5 ppmv for four hours). Likewise, for a single fire in Wyoming, Hg concentrations ranged from 110 to 12,000 ng m (super -3) and vent temperatures varied from 4.1 to >300 degrees C. Whereas these Hg concentrations are below exposure standards, they do suggest that coal fires may be a significant source of hazardous compounds when summed across large coal-bearing regions. Significant variations in the trend of aliphatic concentrations, where compounds were lumped by carbon number, suggest that their abundances may be controlled by differences in source material (e.g., maceral composition and coal rank) and combustion efficacy. Aliphatics larger than C10 (e.g., nonane) were not present in detectable concentrations in any samples; this observation agrees with GC-FID analyses of Kentucky coal samples, which showed a loss of C9-C20 compounds during combustion. Ratios of the total concentrations of aliphatic versus aromatic compounds varied substantially between sites (52-130,000), but generally varied less then an order of magnitude between vents for the same fire, suggesting control by general coal chemistry/environment. Future research directions in the potential environmental impacts of spontaneous coal combustion include characterizing compounds in other types of coals and regions, receptor exposure sampling for gaseous and particulate compounds, toxicological exposure of biological media to coal-fire generated compounds, and epidemiological examination of possible health impacts near coal fires.

Stray gases can originate from oil and gas wells, surface and deep mines, gas-storage reservoirs, as well as buried organic debris and landfills, then migrate into aquifers and built infrastructure such as water wells and buildings. The workshop planners (authors of this abstract) and other scientists and specialists presented investigative techniques and the results of case studies that focused on the origins, migration, and accumulation of stray gases. The focus was on the source identification and mitigation of fugitive methane and carbon dioxide associated with resource extraction. Studies of volcanic or magmatic origins of carbon dioxide and a case study of carbon monoxide poisoning associated with coal mining also were presented. Gas composition including carbon and hydrogen isotopic chemistry, combined with geologic and site characteristics used to define plausible sources, were discussed as primary tools for assessing the origin of fugitive gas. For example, methane associated with thermogenic natural gas typically was enriched in both (super 13) C relative to (super 12) C and (super 2) H relative to (super 1) H and percent modern carbon was negligible as indicated by (super 14) C analyses. In contrast, methane associated with microbial natural gas was enriched in the light isotopes. Case studies from across the U.S. showed that tools and strategies used in one area are applicable elsewhere. The web site http://pa.water.usgs.gov/stray_gas/ serves as a clearinghouse for presentations from the workshop. This presentation summarizes the major themes from the workshop.

Sediments at sites near Concrete, Washington, record two advances of the Baker valley glacier between ca. 30.3 and 19.5 cal ka BP, with an intervening period of glacier recession about 24.9 cal ka BP. The Baker valley glacier dammed lower Skagit valley, creating glacial Lake Concrete, which discharged around the ice dam along Finney Creek, or south into the Sauk valley. Sediments along the shores of Ross Lake in upper Skagit valley accumulated in glacial Lake Skymo after ca. 28.7 cal ka BP behind a glacier flowing out of Big Beaver valley. Horizontally laminated silt and bedded sand and gravel up to 20 m thick record as much as 8000 yr of deposition in these glacially dammed lakes. The data indicate that alpine glaciers in Skagit valley were far less extensive than previously thought. Alpine glaciers remained in advanced positions for much of the Evans Creek stade, which may have ended as early as 20.8 cal ka BP.

Ratios of maximum to minimum mean daily discharge and average recession indices are calculated for watersheds within and surrounding the Yellowstone volcanic plateau. A model for snowmelt recession is used to separate groundwater discharge from overland runoff, and compare groundwater systems. Hydrograph signal interpretation is corroborated with chlorofluorocarbon (CFC) and tritium concentrations in cool water springs on the Yellowstone volcanic plateau. Hydrograph parameters show a spatial pattern correlated with watershed geology. Watersheds comprised dominantly of quaternary Yellowstone volcanics are characterized by slow streamflow recession, low maximum to minimum flow ratios. Cool springs sampled within the Park contain CFC's and tritium and have apparent CFC age dates that range from about 50 years to modern. Watersheds comprised of quaternary Yellowstone volcanics have a large volume of active groundwater circulation. A large, advecting groundwater field would be the dominant mechanism for mass and energy transport in the shallow crust of the Yellowstone volcanic plateau, and thus control the Yellowstone hydrothermal system.

In conjunction with these efforts, 54 fish and habitat surveys were done from 1999 to 2007 at six restored reaches and five stable control reaches to evaluate the effects of NCD restoration on fish assemblages, habitat, and bank stability. A before-after-control-impact study design and two-factor analysis of variance were used to quantify the net changes in habitat and fish population and community indices at treatment reaches relative to those at unaltered control reaches. The density and biomass of fish communities were often dominated by one or two small prey species and no or few predator species before restoration and by one or more trout (Salmonidae) species after restoration. Significant increases in community richness (30%), diversity (40%), species or biomass equitability (32%), and total biomass (up to 52%) in at least four of the six restored reaches demonstrate that NCD restorations can improve the health and sustainability of fish communities in geomorphically unstable Catskill Mountain streams over the short to marginally long term. Bank stability, stream habitat, and trout habitat suitability indices (HSIs) generally improved significantly at the restored reaches, but key habitat features and trout HSIs did not change or decreased at two of them. Fish communities and trout populations at these two reaches were not positively affected by NCD restorations. Though NCD restorations often had a positive effect on habitat and fish communities, our results show that the initial habitat conditions limit the relative improvements than can be achieved, habitat quality and stability do not necessarily respond in unison, and biotic and abiotic responses cannot always be generalized.

Sites were selected to capture a range of nutrient conditions, with 136 sites distributed over five study areas. Samples were collected in either 2003 or 2004, and analyzed for nutrients (nitrogen and phosphorous) and algal biomass (chlorophyll a). Chlorophyll a was measured in three types of samples, fine-grained benthic material (CHL sub(FG)), coarse-grained stable substrate as in rock or wood (CHL sub(CG)), and water column (CHL sub(S)). Stream and riparian habitat were characterized at each site. TP ranged from 0.004-2.69mg/l and TN from 0.15-21.5mg/l, with TN concentrations highest in Nebraska and Indiana streams and TP highest in Nebraska. Benthic algal biomass ranged from 0.47-615mg/m super(2), with higher values generally associated with coarse-grained substrate. Seston chlorophyll ranged from 0.2-73.1kg/l, with highest concentrations in Nebraska. Regression models were developed to predict algal biomass as a function of TP and/or TN. Seven models were statistically significant, six for TP and one for TN; r super(2) values ranged from 0.03 to 0.44. No significant regression models could be developed for the two study areas in the Midwest. Model performance increased when stream habitat variables were incorporated, with 12 significant models and an increase in the r super(2) values (0.16-0.54). Water temperature and percent riparian canopy cover were the most important physical variables in the models. While models that predict algal chlorophyll a as a function of nutrients can be useful, model strength is commonly low due to the overriding influence of stream habitat. Results from our study are presented in context of a nutrient-algal biomass conceptual model.

A popular but controversial stream restoration approach is natural channel design (NCD), which cannot be adequately evaluated without a long-term, independent assessment of its effects on stream habitat. Six reaches of five Catskill Mountain streams in southeastern New York were restored during 2000-2003 following NCD techniques to decrease bed and bank degradation, decrease sediment loads, and improve water quality. Habitat surveys were conducted during summer low flows from 2001 to 2007. The effects of the NCD projects on stream condition were assessed via a before-after-control-impact study design to quantify the net changes in stream and bank habitat variables relative to those in unaltered control reaches. Analysis of variance tests of three different measures of bank stability show that on average stream stability increased at treatment sites for 2-5 years after restoration. Mean channel depth, thalweg depth, and the pool-riffle ratio generally increased, whereas mean channel width, percent streambank coverage by trees, and shade decreased. Habitat suitability indices for local salmonid species increased at four of six reaches after restoration. The changes in channel dimensions rendered them generally more characteristic of stabler stream forms in the given valley settings. Although these studies were done relatively soon after project completion, our findings demonstrate that habitat conditions can be improved in degraded Catskill Mountain streams through NCD restoration.

Geophysical logs and flowmeter/pumping measurements were obtained to estimate vertical profiles of porosity h, hydraulic conductivity K, temperature, and bulk electrical conductivity under background, freshwater conditions. Saline-tracer fluid was then injected into the well for 2 h and its radial migration into the surrounding deposits was monitored by recording an electromagnetic-induction log every 10 min. The field data are analyzed and interpreted primarily through the use of Archie's (1942) law to investigate the role of topological factors such as pore geometry and connectivity, and grain size and packing configuration in regulating fluid flow through these coarse-grained materials. The logs reveal no significant correlation between K and h, and imply that groundwater models that link these two properties may not be useful at this site. Rather, it is the distribution and connectivity of the fluid phase as defined by formation factor F, cementation index m, and tortuosity a that primarily control the hydraulic conductivity. Results show that F correlates well with K, thereby indicating that induction logs provide qualitative information on the distribution of hydraulic conductivity. A comparison of a, which incorporates porosity data, with K produces only a slightly better correlation and further emphasizes the weak influence of the bulk value of h on K.

All of the populations were highly susceptible to the disease upon initial exposure, with significantly greater cumulative mortalities occurring in the exposed treatment groups (56.3-64.3%) than in the unexposed control groups (0.8-9.0%). Interstock differences in cumulative mortality were not significant. The virus loads in the tissues of fish experiencing mortality were 10-10,000 times higher during the acute phase of the epizootics (day 13 postexposure) than during the recovery phase (days 30-42). Survivors of the epizootics were refractory to subsequent VHS, with reexposure of VHS survivors resulting in significantly less cumulative mortality (1.2-4.0%) than among positive controls (38.1-64.4%); interstock differences in susceptibility did not occur after reexposure. These results indicate that data from experiments designed to understand the ecology of VHS virus in a given stock of Pacific herring are broadly applicable to stocks throughout the northeastern Pacific.

During July and August 2007, gill nets were fished in 6 to 8 m of water at two locations of known Hemimysis colonization in southeastern Lake Ontario to determine if fish that consume macroinvertebrates were beginning to include this new invasive mysid in their diets. Of nine fish species captured in August, September, and October 2007, three species had consumed Hemimysis: alewife (Alosa pseudoharengus), rock bass (Ambloplites rupestris), and yellow perch (Perca flavescens); and six species had not: round goby Apollonia melanostoma, smallmouth bass Micropterus dolomieu, spottail shiner Notropis hudsonius, gizzard shad Dorosoma cepedianum, white perch Morone americana and log perch Percina caprodes. Diets of alewives from all samples were composed predominantly of Hemimysis (69.6% -100% frequency of occurrence, 46.0%-74.5% dry weight diet composition). Two of 6 rock bass stomachs sampled in August contained >= 98.9% Hemimysis (10 and 40 individuals each) and one of 61 yellow perch stomachs sampled in September contained 10.0% Hemimysis (6 individuals) and 90.0% fish. While Hemimysis were observed only sparsely in the diet of most nearshore fish, their predominance in alewife diets and their omnivorous feeding behavior indicated that they have the potential to alter energy flow in Great Lakes' foodwebs.

In the present study, absorption of polybrominated diphenyl ether (PBDE) congeners was measured following air cell administration of a penta-BDE mixture (11.1 mu g DE-71g super(-1) egg) or an octa-brominated diphenyl ether mixture (octa-BDE; DE-79; 15.4 mu g DE-79g super(-1) egg). Uptake of PBDE congeners was measured at 24h post-injection, midway through incubation, and at pipping in chicken, mallard (Anas platyrhynchos), and American kestrel egg contents, and at the end of incubation in black-crowned night-heron (Nycticorax nycticorax) egg contents. Absorption of penta-BDE and octa-BDE from the air cell into egg contents occurred throughout incubation; at pipping, up to 29.6% of penta-BDE was absorbed, but only 1.40-6.48% of octa-BDE was absorbed. Higher brominated congeners appeared to be absorbed more slowly than lower brominated congeners, and uptake rate was inversely proportional to the log K ow of predominant BDE congeners. Six congeners or co-eluting pairs of congeners were detected in penta-BDE-treated eggs that were not found in the dosing solution suggesting debromination in the developing embryo, extraembryonic membranes, and possibly even in the air cell membrane. This study demonstrates the importance of determining the fraction of xenobiotic absorbed into the egg following air cell administration for estimation of the lowest-observed-effect level.

The hydraulic properties of lithologic units within the unconfined aquifer and confining unit were computed by analyzing the aquifer-test data using radial, axisymmetric two-dimensional (2D) flow. Time-varying recharge to the unconfined aquifer and pumping from the confined Upper Floridan aquifer (USA) were simulated using 3D flow. Conceptual flow models were developed by gradually reducing the number of lithologic units in the unconfined aquifer and confining unit by calculating composite hydraulic properties for the simplified lithologic units. Composite hydraulic properties were calculated using either thickness-weighted averages or inverse modeling using regression-based parameter estimation. No significant residuals were simulated when all lithologic units comprising the unconfined aquifer were simulated as one layer. The largest residuals occurred when the unconfined aquifer and confining unit were aggregated into a single layer (quasi-3D), with residuals over 100% for the leakage rates to the confined aquifer and the heads in the confining unit. Residuals increased with contrasts in vertical hydraulic conductivity between the unconfined aquifer and confining unit. Residuals increased when the constant-head boundary at the bottom of the Upper Floridan aquifer was replaced with a no-flow boundary.Original Abstract: Les effets de simplifier les proprietes hydrauliques de couches dans un rejeteau aquifer et l'unite de confinant sous-tendante ont ete evalues.

Much has been learned about patterns of phytoplankton variability within individual ecosystems, but patterns have not been compared across the diversity of ecosystem types where marine waters are influenced by connectivity to land. We extracted patterns from chlorophyll-a series measured at 84 estuarine-coastal sites, using a model that decomposes time series into an annual effect, mean seasonal pattern, and residual 'events.' Comparisons across sites revealed a large range of variability patterns, with some dominated by a recurrent seasonal pattern, others dominated by annual (i.e., year-to-year) variability as trends or regime shifts and others dominated by the residual component, which includes exceptional bloom events such as red tides. Why is the partitioning of phytoplankton variability at these three scales so diverse? We propose a hypothesis to guide next steps of comparative analysis: large year-to-year variability is a response to disturbance from human activities or shifts in the climate system; strong seasonal patterns develop where the governing processes are linked to the annual climate cycle; and large event-scale variability occurs at sites highly enriched with nutrients. Patterns of phytoplankton variability are therefore shaped by the site-specific relative importance of disturbance, annual climatology, and nutrient enrichment.

Interestingly, individual trees can persist for decades after salt impact. To understand why, we documented sapflow (J sub(s)), reduction in J sub(s) with sapwood depth, and water use (F) of baldcypress (Taxodium distichum (L.) Rich.) trees undergoing exposure to salinity. The mean J sub(s) of individual trees was reduced by 2.8 g H sub(2)O.m super(-2).s super(-1) (or by 18%) in the outer sapwood on a saline site versus a freshwater site; however, the smallest trees, present only on the saline site, also registered the lowest J sub(s). Hence, tree size significantly influenced the overall site effect on J sub(s). Trees undergoing perennial exposure to salt used greater relative amounts of water in outer sapwood than in inner sapwood depths, which identifies a potentially different strategy for baldcypress trees coping with saline site conditions over decades. Overall, individual trees used 100 kg H sub(2)O.day super(-1) on a site that remained relatively fresh versus 23.9 kg H sub(2)O.day super(-1) on the saline site. We surmise that perennial salinization of coastal freshwater forests forces shifts in individual-tree osmotic balance and water-use strategy to extend survival time on suboptimal sites, which further influences growth and morphology.Original Abstract: L'elevation du niveau de la mer et l'activite anthropogenique favorise l'incursion de l'eau salee dans les zones intertidales d'eau douce boisees. Il est interessant de constater que des arbres peuvent persister pendant des decennies apres avoir subi l'impact du sel. Afin de comprendre pourquoi, nous avons documente l'ecoulement de la seve (J sub(s)), la diminution de J sub(s) en fonction de la profondeur dans le bois d'aubier et l'utilisation de l'eau chez des tiges de taxode chauve (Taxodium distichum (L.) Rich.) exposees a l'eau salee. La valeur moyenne de J sub(s) chez les individus testes etait reduite de 2,8 g H sub(2)O.m super(-2).s super(-1) (ou 18 %) dans la partie externe de l'aubier sur une station saline comparativement a une station d'eau douce. Cependant, les plus petits arbres, presents seulement sur la station saline, avaient aussi les plus faibles valeurs de J sub(s). Par consequent, la dimension des arbres influence de facon significative l'effet global de la station sur J sub(s). Les arbres qui subissaient une exposition chronique au sel utilisaient de plus grandes quantites relatives d'eau dans la partie externe de l'aubier que dans la partie interne, ce qui constitue peut-etre une strategie differente chez les tiges de taxode qui tolerent les conditions de salinite de la station pendant plusieurs decennies. Globalement, les arbres utilisaient 100 kg H sub(2)O.jour super(-1) sur une station ou l'eau demeure relativement douce versus 23,9 kg H sub(2)O.jour super(-1) sur la station saline. Nous faisons l'hypothese que la salinisation des forets dans les marais cotiers d'eau douce force les arbres a modifier leur equilibre osmotique et leur strategie d'utilisation de l'eau pour allonger leur periode de survie sur des stations sous-optimales, ce qui influence ensuite leur croissance et leur morphologie.

Currently, there is no universal standard for sample collection and analysis or results interpretation. Monitoring policies are developed by individual beach management jurisdictions, and applications are highly variable across and within lakes, states, and provinces. Extensive research has demonstrated that sampling decisions for time, depth, number of replicates, frequency of sampling, and laboratory analysis all influence the results outcome, as well as calculations of the mean and interpretation of the results in policy decisions. Additional shortcomings to current monitoring approaches include appropriateness and reliability of currently used indicator bacteria and the overall goal of these monitoring programs. Current research is attempting to circumvent these complex issues by developing new tools and methods for beach monitoring. In this review, we highlight the variety of sampling routines used across the Great Lakes and the extensive body of research that challenges comparisons among beaches. We also assess the future of Great Lakes monitoring and the advantages and disadvantages of establishing standards that are evenly applied across all beaches.

Due in part to the species' lack of popularity as a game and commercial fish, few regions consider burbot in management plans. We review the worldwide population status of burbot and synthesize reasons why some burbot populations are endangered or declining, some burbot populations have recovered and some burbot populations do not recover despite management measures. Burbot have been extirpated in much of Western Europe and the United Kingdom and are threatened or endangered in much of North America and Eurasia. Pollution and habitat change, particularly the effects of dams, appear to be the main causes for declines in riverine burbot populations. Pollution and the adverse effects of invasive species appear to be the main reasons for declines in lacustrine populations. Warmer water temperatures, due either to discharge from dams or climate change, have been noted in declining burbot populations at the southern extent of their range. Currently, fishing pressure does not appear to be limiting burbot populations world-wide. We suggest mitigation measures for burbot population recovery, particularly those impacted by dams and invasive species.

Sirenian conservation and management actions would benefit from a more complete understanding of genetic diversity and population structure. Generally, species-specific microsatellite markers are employed in conservation genetic studies; however, robust markers can be difficult and costly to isolate. To increase the number of available markers, dugong and manatee microsatellite primers were evaluated for cross-species amplification. Furthermore, one manatee and four dugong novel primers are reported. After polymerase chain reaction optimization, 23 (92%) manatee primers successfully amplified dugong DNA, of which 11 (48%) were polymorphic. Of the 32 dugong primers tested, 27 (84%) yielded product in the manatee, of which 17 (63%) were polymorphic. Dugong and manatee primers were compared and the most informative markers were selected to create robust and informative marker-panels for each species. These cross-species microsatellite marker-panels can be employed to assess other sirenian populations and can provide beneficial information for the protection and management of these unique mammals.

This experiment was repeated in triplicate. Results showed that cycle threshold values were statistically different among the different lots.Conclusions: Differences in DNA extraction reagent lots were found to be a significant source of variability for qPCR results. Steps should be taken to ensure the quality and consistency of reagents. Minimally, we propose that standard curves should be constructed for each new lot of extraction reagents, so that lot-to-lot variation is accounted for in data interpretation.Significance and Impact of the Study: This study highlights the importance of evaluating variability in DNA extraction procedures, especially when different reagent lots are used. Consideration of this variability in data interpretation should be an integral part of studies investigating environmental samples with unknown concentrations of organisms.

However, the choice of variables and how they are used to quantify disturbance are often subjective. In this study, we developed a number of disturbance indices by testing sets of variables, scoring methods, and weightings of 33 potential disturbance factors derived from readily available GIS data. The indices were calibrated using 770 watersheds located in the western United States for which the severity of disturbance had previously been classified from detailed local data by the United States Environmental Protection Agency (USEPA) Environmental Monitoring and Assessment Program (EMAP). The indices were calibrated by determining which variable or variable combinations and aggregation method best differentiated between least- and most-disturbed sites. Indices composed of several variables performed better than any individual variable, and best results came from a threshold method of scoring using six uncorrelated variables: housing unit density, road density, pesticide application, dam storage, land cover along a mainstem buffer, and distance to nearest canal/pipeline. The final index was validated with 192 withheld watersheds and correctly classified about two-thirds (68%) of least- and most-disturbed sites. These results provide information about the potential for using a disturbance index as a screening tool for a priori ranking of watersheds at a regional/national scale, and which landscape variables and methods of combination may be most helpful in doing so.

There were no effects of Hg on adult weights and no overt signs of Hg poisoning in adults. The Hg-containing diet had no effect on fertility of eggs, but hatching success of eggs was significantly higher for females fed 0.5 [mu]g/g Hg (71.8%) than for controls (57.5%). Survival of ducklings through 6 d of age was the same (97.8%) for controls and mallards fed 0.5 [mu]g/g mercury. However, the mean number of ducklings produced per female was significantly higher for the pairs fed 0.5 [mu]g/g Hg (21.4) than for controls (16.8). Although mercury in the parents' diet had no effect on mean duckling weights at hatching, ducklings from parents fed 0.5 [mu]g/g Hg weighed significantly more (mean = 87.2 g) at 6 d of age than did control ducklings (81.0 g). The mean concentration of Hg in eggs laid by parents fed 0.5 [mu]g/g mercury was 0.81 [mu]g/g on a wet-weight basis. At this time, one cannot rule out the possibility that low concentrations of Hg in eggs may be beneficial, and this possibility should be considered when setting regulatory thresholds for methylmercury.

Here we use the General Ensemble biogeochemical Modeling System to simulate the terrestrial ecosystem carbon dynamics in the Jinsha watershed of China's upper Yangtze basin from 1975 to 2000, based on unique combinations of spatial and temporal dynamics of major driving forces, such as climate, soil properties, nitrogen deposition, and land use and land cover changes. Our analysis demonstrates that the Jinsha watershed ecosystems acted as a carbon sink during the period of 1975-2000, with an average rate of 0.36Mg/ha/yr, primarily resulting from regional climate variation and local land use and land cover change. Vegetation biomass accumulation accounted for 90.6% of the sink, while soil organic carbon loss before 1992 led to a lower net gain of carbon in the watershed, and after that soils became a small sink. Ecosystem carbon sink/source patterns showed a high degree of spatial heterogeneity. Carbon sinks were associated with forest areas without disturbances, whereas carbon sources were primarily caused by stand-replacing disturbances. It is critical to adequately represent the detailed fast-changing dynamics of land use activities in regional biogeochemical models to determine the spatial and temporal evolution of regional carbon sink/source patterns.

As part of this multidisciplinary research project, 80 samples of water were collected from 10 shallow monitoring wells (1.5 or 3.0 m deep) installed 1-6 m from the injection pipe, at the southwestern end of the slotted section (zone VI), and from two distant monitoring wells. The samples were collected before, during, and following CO sub(2) injection. The main objective of study was to investigate changes in the concentrations of major, minor, and trace inorganic and organic compounds during and following CO sub(2) injection. The ultimate goals were (1) to better understand the potential of groundwater quality impacts related to CO sub(2) leakage from deep storage operations, (2) to develop geochemical tools that could provide early detection of CO sub(2) intrusion into underground sources of drinking water (USDW), and (3) to test the predictive capabilities of geochemical codes against field data. Field determinations showed rapid and systematic changes in pH (7.0-5.6), alkalinity (400-1,330 mg/l as HCO sub(3)), and electrical conductance (600-1,800 mu S/cm) following CO sub(2) injection in samples collected from the 1.5 m-deep wells. Laboratory results show major increases in the concentrations of Ca (90-240 mg/l), Mg (25-70 mg/l), Fe (5-1,200 ppb), and Mn (5-1,400 ppb) following CO sub(2) injection. These chemical changes could provide early detection of CO sub(2) leakage into shallow groundwater from deep storage operations. Dissolution of observed carbonate minerals and desorption-ion exchange resulting from lowered pH values following CO sub(2) injection are the likely geochemical processes responsible for the observed increases in the concentrations of solutes; concentrations generally decreased temporarily following four significant precipitation events. The DOC values obtained are 5 +/- 2 mg/l, and the variations do not correlate with CO sub(2) injection. CO sub(2) injection, however, is responsible for detection of BTEX (e.g. benzene, 0-0.8 ppb), mobilization of metals, the lowered pH values, and increases in the concentrations of other solutes in groundwater. The trace metal and BTEX concentrations are all significantly below the maximum contaminant levels (MCLs). Sequential leaching of core samples is being carried out to investigate the source of metals and other solutes.

When analyzed, these individual food items have traditionally been treated as independent, which represents pseudoreplication. When food types are recorded as present or absent, these samples can be treated as multinomial vectors of food items, with each vector representing 1 realization of a possible diet. We suggest such data have a similar structure to capture histories for closed-capture, capture-mark-recapture data. To assess the effects of landscapes and presence of a potential competitor, we used closed-capture models implemented in program MARK into analyze diet data generated from feces of swift foxes (Vulpes velox) and coyotes (Canis latrans) in northwestern Texas. The best models of diet contained season and location for both swift foxes and coyotes, but year accounted for less variation, suggesting that landscape type is an important predictor of diets of both species. Models containing the effect of coyote reduction were not competitive ( Delta QAICc = 53.6685), consistent with the hypothesis that presence of coyotes did not influence diet of swift foxes. Our findings suggest that landscape type may have important influences on diets of both species. We believe that multinomial models represent an effective approach to assess hypotheses when diet studies have a data structure similar to ours.

AN - 907152528; 14134641 AB - The major forces of food and predation shape fitness-enhancing decisions of birds at all stages of their life cycles. During the breeding season, birds can minimize nest loss due to predation by selecting sites with a lower probability of predation. To understand the environmental and social aspects and consequences of breedingsite selection in prairie birds, we explored variation in nest-survival patterns of the Lark Bunting (Calamospiza melanocorys) in the shortgrass prairie region of North America. Over four breeding seasons, we documented the survival of 405 nests, conducted 60 surveys to estimate bird densities, and measured several vegetative features to describe habitat structure in 24 randomly selected study plots. Nest survival varied with the buntings' density as described by a quadratic polynomial, increasing with density below 1.5 birds ha-1 and decreasing with density between 1.5 and 3 birds ha-1, suggesting that an optimal range of densities favors reproductive success of the Lark Bunting, which nests semi-colonially. Nest survival also increased with increasing vegetation structure of study plots and varied with age of the nest, increasing during early incubation and late in the nestling stage and declining slightly from mid-incubation to the middle of the nestling period. The existence of an optimal range of densities in this semi-colonial species can be elucidated by the "commodity-selection hypothesis" at low densities and density dependence at high densities.

Nutrient concentration and flux in the Mississippi River have increased substantially over the last century because of changes in land use, climate, hydrology, and river management and engineering. As in other large floodplain rivers, rates of processes that cycle nitrogen and phosphorus in the UMR exhibit pronounced spatial and temporal heterogeneity because of the complex morphology of the river. This spatial variability in nutrient processing creates clear spatial patterns in nutrient concentrations. For example, nitrate concentrations generally are much lower in off-channel areas than in the main channel. The specifics of in-river nutrient cycling and the effects of high rates of nutrient input on UMR have been less studied than the factors affecting nutrient input to the river and transport to the Gulf of Mexico, and important questions concerning nutrient cycling in the UMR remain. Eutrophication and resulting changes in river productivity have only recently been investigated the UMR. These recent studies indicate that the high nutrient concentrations in the river may affect community composition of aquatic vegetation (e.g., the abundance of filamentous algae and duckweeds), dissolved oxygen concentrations in off-channel areas, and the abundance of cyanobacteria. Actions to reduce nutrient input to the river include changes in land-use practices, wetland restoration, and hydrological modifications to the river. Evidence suggests that most of the above methods can contribute to reducing nutrient concentration in, and transport by, the UMR, but the impacts of mitigation efforts will likely be only slowly realized.

Toxicity tests of anion mixtures were used to determine interaction effects and to produce models predicting C. dubia reproduction. Effluents diluted with low- and moderate-hardness waters were tested with animals acclimated to low- and moderate-hardness conditions to evaluate the models and to assess the effects of hardness and acclimation. Sulfate was significantly less toxic than Cl super(-) and HCO in both types of water. Chloride and HCO toxicities were similar in low-hardness water, but HCO was the most toxic in moderate-hardness water. Low acute-to-chronic ratios indicate that toxicities of these anions will decrease quickly with dilution. Hardness significantly reduced Cl super(-) and SO4 toxicity but had little effect on HCO. Chloride toxicity decreased with an increase in Na super(+) concentration, and HCO toxicity may have been reduced by the dissolved organic carbon in effluent. Multivariate models using measured anion concentrations in effluents with low to moderate hardness levels provided fairly accurate predictions of reproduction. Determinations of toxicity for several effluents differed significantly depending on the hardness of the dilution water and the hardness of the water used to culture test animals. These results can be used to predict the contribution of elevated anion concentrations to the chronic toxicity of effluents; to identify effluents that are toxic due to contaminants other than Cl super(-), SO4, and HCO3; and to provide a basis for chemical substitutions in manufacturing processes.

When eggs cannot be sampled, some substitute tissue, such as female blood, the diet of the breeding female, or down feathers of hatchlings, must be used. When female mallards (Anas platyrhynchos) were fed diets containing methylmercury chloride, the concentration of Hg in a sample of their blood was closely correlated with the concentration of Hg in the egg they laid the day they were bled (r super(2) = 0.88; p < 0.001). Even when the blood sample was taken more than two weeks after an egg was laid, there was a strong correlation between Hg concentrations in female blood and eggs (r super(2) = 0.67; p < 0.0002). When we plotted the dietary concentrations of Hg we fed to the egg-laying females against the concentrations of Hg in their eggs, the r super(2) value was 0.96 (p < 0.0001). When the concentrations of Hg in the down feathers of newly hatched ducklings were plotted against Hg in the whole ducklings, the r super(2) value was 0.99 (p < 0.0003). Although measuring Hg in eggs may be the most direct way of predicting possible embryotoxicity, our findings demonstrate that measuring Hg in the diet of breeding birds, in the blood of egg-laying females, or in down feathers of hatchlings all can be used to estimate what concentration of Hg may have been in the egg.

The objective of such studies is often to estimate population size; however, doing so is frequently complicated by movement of individual bears. Movement affects the probability of detection and the assumption of closure of the population required in most models. To mitigate the bias caused by movement of individuals, population size and density estimates are often adjusted using ad hoc methods, including buffering the minimum polygon of the trapping array. We used a hierarchical, spatial capture-recapture model that contains explicit components for the spatial-point process that governs the distribution of individuals and their exposure to (via movement), and detection by, traps. We modeled detection probability as a function of each individual's distance to the trap and an indicator variable for previous capture to account for possible behavioral responses. We applied our model to a 2006 hair-snare study of a black bear (Ursus americanus) population in northern New York, USA. Based on the microsatellite marker analysis of collected hair samples, 47 individuals were identified. We estimated mean density at 0.20 bears/km2. A positive estimate of the indicator variable suggests that bears are attracted to baited sites; therefore, including a trap-dependence covariate is important when using bait to attract individuals. Bayesian analysis of the model was implemented in WinBUGS, and we provide the model specification. The model can be applied to any spatially organized trapping array (hair snares, camera traps, mist nests, etc.) to estimate density and can also account for heterogeneity and covariate information at the trap or individual level.

Recoveries of tarsus bands from Vancouver Canada geese (B. canadensis fulva) marked in southeast Alaska, USA, greater than or equal to 4 decades ago suggested that greater than or equal to 83% of the population was non-migratory and that annual adult survival was high (S [circumflex] = 0.836). However, recovery distribution of tarsus bands was potentially biased due to geographic differences in harvest intensity in the Pacific Flyway. Also, winter distribution of Vancouver Canada geese could have shifted since the 1960s, as has occurred for some other populations of Canada geese. Because winter distribution and annual survival of this population had not recently been evaluated, we surgically implanted very high frequency radiotransmitters in 166 adult female Canada geese in southeast Alaska. We captured Vancouver Canada geese during molt at 2 sites where adults with goslings were present (breeding areas) and 2 sites where we observed nonbreeding birds only. During winter radiotracking flights in southeast Alaska, we detected 98% of 85 females marked at breeding areas and 83% of 70 females marked at nonbreeding sites, excluding 11 females that died prior to the onset of winter radiotracking. We detected no radiomarked females in coastal British Columbia, or western Washington and Oregon, USA. Most (70%) females moved less than or equal to 30 km between November and March. Our model-averaged estimate of annual survival (S [circumflex] = 0.844, SE = 0.050) was similar to the estimate of annual survival of geese marked from 1956 to 1960. Likely <2% of Vancouver Canada geese that nest in southeast Alaska migrate to winter areas in Oregon or Washington where they could intermix with Canada geese from other populations in the Pacific Flyway. Because annual survival of adult Vancouver Canada geese was high and showed evidence of long-term consistency, managers should examine how reproductive success and recruitment may affect the population.

Meanwhile, distinct population segments of the gray wolf (Canis lupus) have been removed from the list of endangered and threatened species, implying an end to wolf recovery and reintroductions. We propose another paradigm for wolf conservation, one that emphasizes ecosystem recovery instead of wolf recovery. Improvements in technology, an enhanced understanding of the ecological role of wolves, lessons from other countries, and changing public attitudes provide a new context and opportunity for wolf conservation and ecosystem restoration. Under this new paradigm, small populations of wolves, even single packs, could be restored to relatively small natural areas for purposes of ecosystem restoration and stewardship. We acknowledge the complications and challenges involved in such an effort, but assert that the benefits could be substantial.

These results are the first for the Caribbean and were derived with likelihood-based approaches from 4640 nests and 44 chicks fitted with transmitters monitored in 52 colonies at St. Croix, U.S. Virgin Islands, 2003-2006. Managed colonies excluded, overall daily nest survival ( plus or minus SE) was 0.92 plus or minus 0.03 (period survival = 0.18). Daily nest survival of managed colonies (fenced) was significantly higher (0.97 plus or minus 0.02; period survival = 0.51). Variation in nest survival was best explained by a negative linear trend in daily survival, influenced by year, rain, large colony size, and nesting habitat. Daily nest-survival rates at sandy beaches (0.94 plus or minus 0.02), offshore cays (0.93 plus or minus 0.005), and saltflats (0.91 plus or minus 0.02) did not differ significantly. The period survival of chicks was 0.30 plus or minus 0.11. Estimated fledglings per nest attempt were 0.06. Demographic assessments suggested that higher reproductive rates are required for maintenance ( lambda greater than or equal to 1). Managed colonies could meet nest-survival thresholds, but complementary measures are needed to increase chick survival. Our findings suggest that management should target sites harboring large colonies because they had higher nest success and higher probability of use in subsequent seasons. The colonies' site dynamics suggested that immigration from other populations is plausible. This possibility relaxes breeding-productivity thresholds and advocates for coordinated conservation among populations on neighboring islands. Estimates of age-specific survival and connectivity are needed for the status of the species to be assessed appropriately and conservation priorities set.

Holding-time experiments were done for fecal coliform using the membrane filtration modified fecal coliform (mFC) agar method and for total coliform and E. coli using the Colilert super(+)-18 Quanti-Tray super(+) method. The precisions of these analytical methods were quantified. Precisions determined for fecal coliform indicated that the upper bound of the ideal range of counts could reasonably be extended upward and would improve precision. For the Colilert super(+)-18 method, analytical precisions were similar to the theoretical precisions for this method. Fecal and total coliform densities did not change significantly with holding times up to about 27h. Limited information indicated that fecal coliform densities might be stable for holding times of up to 62h, whereas total coliform densities might not be stable for holding times greater than about 27h. E. coli densities were stable for holding times of up to 18h--a shorter period than indicated from a previous studies. These results should be applicable to non-regulatory monitoring sampling designs for similar urban surface-water sample types.

These processes are of great importance to the US Geological Survey's (USGS) Prompt Assessment of Global Earthquakes for Response (PAGER) system, which is currently being developed to deliver rapid earthquake impact and loss assessments following large/significant global earthquakes. An important question is how dominant are losses due to secondary effects (and under what conditions, and in which regions)? Thus, which of these effects should receive higher priority research efforts in order to enhance PAGER's overall assessment of earthquakes losses and alerting for the likelihood of secondary impacts? We find that while 21.5% of fatal earthquakes have deaths due to secondary (non-shaking) causes, only rarely are secondary effects the main cause of fatalities. The recent 2004 Great Sumatra-Andaman Islands earthquake is a notable exception, with extraordinary losses due to tsunami. The potential for secondary hazards varies greatly, and systematically, due to regional geologic and geomorphic conditions. Based on our findings, we have built country-specific disclaimers for PAGER that address potential for each hazard (Earle et al., Proceedings of the 14th World Conference of the Earthquake Engineering, Beijing, China, 2008). We will now focus on ways to model casualties from secondary effects based on their relative importance as well as their general predictability.

Microgeographic genetic structure in a philopatric sea duck AN - 746226998; 12793259 AB - AbstractWe investigated local genetic associations among female Pacific common eiders (Somateria mollissima v-nigrum) nesting in a stochastic Arctic environment within two groups of barrier islands (Simpson Lagoon and Mikkelsen Bay) in the Beaufort Sea, Alaska. Nonrandom genetic associations were observed among nesting females using regional spatial autocorrelation analyses for distance classes up to 1000 m in Simpson Lagoon. Nearest-neighbour analyses identified clusters of genetically related females with positive lr values observed for 0-13% and 0-7% of the comparisons in Simpson Lagoon and Mikkelsen Bay, respectively, across years. These results indicate that a proportion of females are nesting in close proximity to more genetically related individuals, albeit at low frequency. Such kin groupings may form through active association between relatives or through natal philopatry and breeding site fidelity. Eiders nest in close association with driftwood, which is redistributed annually by seasonal storms. Yet, genetic associations were still observed. Microgeographic structure may thus be more attributable to kin association than natal philopatry and site fidelity. However, habitat availability may also influence the level of structure observed. Regional structure was present only within Simpson Lagoon and this island group includes at least three islands with sufficient driftwood for colonies, whereas only one island at Mikkelsen Bay has these features. A long-term demographic study is needed to understand more fully the mechanisms that lead to fine-scale genetic structure observed in common eiders breeding in the Beaufort Sea.

The complex effects of disturbances on ecological communities can be further complicated by subsequent perturbations within an ecosystem. We investigated how wildfire interacts with annual variations in peak streamflow to affect the stability of stream macroinvertebrate communities in a central Idaho wilderness, USA. We conducted a 4-year retrospective analysis of unburned (n = 7) and burned (n = 6) catchments, using changes in reflectance values (NBR) from satellite imagery to quantify the percentage of each catchment's riparian and upland vegetation that burned at high and low severity.2. For this wildland fire complex, increasing riparian burn severity and extent were associated with greater year-to-year variation, rather than a perennial increase, in sediment loads, organic debris, large woody debris (LWD) and undercut bank structure. Temporal changes in these variables were correlated with yearly peak flow in burned catchments but not in unburned reference catchments, indicating that an interaction between fire and flow can result in decreased habitat stability in burned catchments.3. Streams in more severely burned catchments exhibited increasingly dynamic macroinvertebrate communities and did not show increased similarity to reference streams over time. Annual variability in macroinvertebrates was attributed, predominantly, to the changing influence of sediment, LWD, riparian cover and organic debris, as quantities of these habitat components fluctuated annually depending on burn severity and annual peak streamflows.4. These analyses suggest that interactions among fire, flow and stream habitat may increase inter-annual habitat variability and macroinvertebrate community dynamics for a duration approaching the length of the historic fire return interval of the study area.

Catch rate varied with year, season and the diel period during which sampling was conducted as well as by the interaction between year and season. Indices of abundance of age-0 and age-1 yellow perch estimated from night samples typically produced better fitting models and lower estimates of age-2 abundance than those using morning or afternoon samples, whereas indices using afternoon samples typically produced less precise and higher estimates of abundance. The diel period during which sampling is conducted will not affect observed population trends but may affect estimates of abundance of age-0 and age-1 yellow perch, which in turn affect recommended allowable harvest.

Compared with uncontaminated groundwater, the plume chemistry diminished bacterial attachment under mildly acidic (pH 5.0-6.5) in-situ conditions, in spite of the 5-fold increase in ionic strength and substantively enhanced attachment under more alkaline conditions. The effects of the hydrophobic neutral and total fractions of the plume DOC; modest concentrations of fulvic and humic acids (1.5mg/L); linear alkyl benzene sulfonate (LAS) (25mg/L); Imbentin (200 mu g/L), a model nonionic surfactant; sulfate (28mg/L); and calcium (20mg/L) varied sharply in response to relatively small changes in pH, although the plume constituents collectively decreased the pH-dependency of bacterial attachment. LAS and other hydrophobic neutrals (collectively representing only 3% of the plume DOC) had a disproportionately large effect upon bacterial attachment, as did the elevated concentrations of sulfate within the plume. The findings further suggest that the roles of organic plume constituents in transport or bacteria through acidic aquifer sediments can be very different than would be predicted from column studies performed at circumneutral pH and that the inorganic constituents within the plume cannot be ignored.

Knowledge of the natural flow regime facilitates the assessment of whether specific hydrologic attributes have been altered by humans in a particular stream and the establishment of specific goals for stream-flow restoration. Because most streams are ungaged or have been altered by human influences, characterizing the natural flow regime is often only possible by estimating flow characteristics based on nearby stream gages of reference quality, i.e., gaged locations that are least disturbed by human influences. The ability to evaluate natural stream flow, that which is not altered by human activities, would be enhanced by the existence of a nationally consistent and up-to-date database of gages in relatively undisturbed watersheds. As part of a national effort to characterize stream-flow effects on ecological condition, data for 6785 U.S. Geological Survey (USGS) stream gages and their upstream watersheds were compiled. The sites comprise all USGS stream gages in the conterminous United States with at least 20 years of complete-year flow record from 1950-2007, and for which watershed boundaries could reliably be delineated (median size = 578 km super(2)). Several hundred watershed and site characteristics were calculated or compiled from national data sources, including environmental features (e.g., climate, geology, soils, topography) and anthropogenic influences (e.g., land use, roads, presence of dams, or canals). In addition, watersheds were assessed for their reference quality within nine broad regions for use in studies intended to characterize stream flows under conditions minimally influenced by human activities. Three primary criteria were used to assess reference quality: (1) a quantitative index of anthropogenic modification within the watershed based on GIS-derived variables, (2) visual inspection of every stream gage and drainage basin from recent high-resolution imagery and topographic maps, and (3) information about man-made influences from USGS Annual Water Data Reports. From the set of 6785 sites, we identified 1512 as reference-quality stream gages. All data derived for these watersheds as well as the reference condition evaluation are provided as an online data set termed GAGES (geospatial attributes of gages for evaluating stream flow).

Rates of carbon storage result from the balance of inputs and losses, both of which are affected by wetland hydrology. We followed the effect of water depth (25 and 55cm) on the plant community, primary production, and changes in two re-established wetlands in the Sacramento San-Joaquin River Delta, California for 9years after flooding to determine how relatively small differences in water depth affect carbon storage rates over time. To estimate annual carbon inputs, plant species cover, standing above- and below-ground plant biomass, and annual biomass turnover rates were measured, and allometric biomass models for Schoenoplectus (Scirpus) acutus and Typha spp., the emergent marsh dominants, were developed. As the wetlands developed, environmental factors, including water temperature, depth, and pH were measured. Emergent marsh vegetation colonized the shallow wetland more rapidly than the deeper wetland. This is important to potential carbon storage because emergent marsh vegetation is more productive, and less labile, than submerged and floating vegetation. Primary production of emergent marsh vegetation ranged from 1.3 to 3.2kg of carbon per square meter annually; and, mid-season standing live biomass represented about half of the annual primary production. Changes in species composition occurred in both submerged and emergent plant communities as the wetlands matured. Water depth, temperature, and pH were lower in areas with emergent marsh vegetation compared to submerged vegetation, all of which, in turn, can affect carbon cycling and storage rates.

Previous experimental and analytical studies of natural convective flow in an inclined porous layer have shown that there are a variety of convective modes possible depending on system parameters, geometry and inclination. In particular, there is a well-defined transition from the helicoidal mode consisting of downslope longitudinal rolls superimposed upon an upslope unicellular roll to a mode consisting of purely an upslope unicellular roll. Three-dimensional benchmarks for variable-density simulators are currently (2009) lacking and comparison of simulation results with this transition locus provides an unambiguous means to test the ability of such simulators to represent steady-state unstable 3D variable-density physics.Original Abstract: Ce banc d'essai pour simulation numerique tridimensionnelle (3D) d'un flot d'ecoulement souterrain de densite ou d'energie variable permet de comparer les resultats semi-analytiques de transition d'un mode convectif en regime permanent a un autre, dans une boite poreuse. Des etudes experimentales et analytiques anterieures de flux convectif libre dans un milieu poreux incline ont montre qu'il existe differents modes de convection possibles dependant des parametres du systeme, geometrie et inclinaison. En particulier, il existe une transition nette entre le mode helicoiedal, consistant en ecoulements longitudinaux descendants surimposes a un flux unicellulaire ascendant et un mode d'ecoulement unicellulaire purement ascendant. Des bancs d'essai tri-dimensionnels pour simulations d'ecoulements de densite variable manquent actuellement (2009) et la comparaison de simulations avec ce dispositif de transition montre clairement la capacite de tels simulateurs a representer en 3 dimensions la physique des phenomenes instables en regime permanent.

Interpretation of tomograms for hydrologic processes is complicated by inversion artifacts, uncertainty associated with survey geometry limitations, measurement errors, and choice of regularization method. Variation of seawater over tidal cycles poses unique challenges for inversion. The capabilities and limitations of resistivity imaging are presented for characterizing the distribution of freshwater and saltwater beneath a beach. The experimental results provide new insight into fresh submarine groundwater discharge at Waquoit Bay National Estuarine Research Reserve, East Falmouth, Massachusetts (USA). Tomograms from the experimental data indicate that fresh submarine groundwater discharge may shut down at high tide, whereas temperature data indicate that the discharge continues throughout the tidal cycle. Sensitivity analysis and synthetic modeling provide insight into resolving power in the presence of a time-varying saline water layer. In general, vertical electrodes and cross-hole measurements improve the inversion results regardless of the tidal level, whereas the resolution of surface arrays is more sensitive to time-varying saline water layer.Original Abstract: L'imagerie de la resistivite electrique a ete utilisee en environnement cotier pour caracteriser les arrivees d'eau douce souterraine ainsi que la position de l'interface eau salee/eau douce, du fait que la relation entre la conductivite electrique des blocs et la conductivite du fluide de la porosite est fonction de la salinite. L'interpretation de tomographes a des fins hydrologiques est complexe a cause des artefacts d'inversion, de l'incertitude associee aux limites geometriques du domaine investiguee, des erreurs de mesures et du choix de la methode de regularisation. La variabilite de l'eau de mer en fonction des cycles de maree constitue un reel defi pour les techniques d'inversion. Les capacites et les limites de l'imagerie de la resistivite sont presentees, afin de caracteriser la distribution de l'eau douce et de l'eau salee sous une plage.

Les tomographes des donnees experimentales indiquent que la decharge des eaux souterraines peut etre interrompue lors de marees de forte intensite, alors que les donnees de temperature montrent que la decharge se poursuit tout au long du cycle de la maree. Les analyses de sensibilite ainsi qu'une modelisation synthetique fournissent de nouvelles informations concernant la resolution d'un niveau d'eau ayant une salinite qui varie dans le temps. De maniere generale, les electrodes verticales et les mesures croisees ameliorent les resultats d'inversion independamment des niveaux de maree, alors que la resolution des signaux de surface est plus sensible pour le niveau d'eau salee variant dans le temps.

Future scenarios were simulated with two pumping schemes to predict potential areas of saltwater intrusion. Simulations suggest that only a few wells would be threatened with detectable salinity increases before 2050. The objective was to examine whether salinity increases can be accurately forecast for individual wells with such a model, and to address what the challenges are in making such model forecasts given current (2009) simulation capabilities. The analysis suggests that even with current computer capabilities, accurate simulations of concentrations within a regional-scale (many km) transition zone are computationally prohibitive. The relative paucity of data that is typical for such regions relative to what is needed for accurate transport simulations suggests that even with an infinitely powerful computer, accurate forecasting for a single well would still be elusive. Useful approaches may include local-grid refinement near wells and geophysical surveys, but it is important to keep expectations for simulated forecasts at wells in line with chloride concentration and other data that can be obtained at that local scale.Original Abstract: Un modele tridimensionnel du systeme aquifere de la cote est de la Virginie, USA, a ete cale pour reproduire les historiques des niveaux d'eau et pour predire les risques d'intrusion d'eau de mer. Des scenarios futurs ont ete simules pour deux systemes de pompage, en vue de predire les zones ou l'intrusion d'eau de mer est possible. Ces simulations laissent a penser que seuls quelques puits seraient menaces par des hausses detectables de salinite avant 2050. L'objectif etait d'evaluer si les augmentations de salinite pouvaient etre precisement predites pour des puits particuliers avec un tel modele, et d'aborder les defis que poserait la realisation de tels modeles de prediction compte tenu des capacites de simulation actuelles (2009). L'analyse montre que, meme avec les moyens de calculs actuels, des simulations precises de concentration a l'interieur d'une zone de transition a l'echelle regionale (plusieurs kilometres) sont prohibitives d'un point de vue calculatoire. Au vu du manque relatif de donnees, caracteristique de telles regions, au regard des besoins pour des simulations du transport precises, il apparait que meme avec un ordinateur de puissance illimitee, une prevision precise pour un puits unique restera hors d'atteinte. Une discretisation fine du maillage a proximite des puits et une prospection geophysique peuvent etre utiles, mais il convient que les attentes en termes de previsions simulees soient conformes aux concentrations en chlore et aux autres donnees qui peuvent etre obtenues cette echelle locale.

A two-dimensional cross-section model was used to evaluate the effects of hydraulic heterogeneities, cooling canal salinity, heat transport, and cooling canal geometry on aquifer salinization and movement of the freshwater/saltwater interface. Four different hydraulic conductivity configurations, with values ranging over several orders of magnitude, were evaluated with the model. For all of the conditions evaluated, aquifer salinization was initiated by the formation of dense, hypersaline fingers that descended downward to the bottom of the 30-m thick aquifer. Saline fingers reached the aquifer bottom in times ranging from a few days to approximately 5 years for the lowest hydraulic conductivity case. Aquifer salinization continued after saline fingers reached the aquifer bottom and coalesced by lateral movement away from the site. Model results showed that aquifer salinization was most sensitive to aquifer heterogeneity, but was also sensitive to CCS salinity, temperature, and configuration.Original Abstract: L'effet combine de la salinite et la temperature sur la convection due a la densite a ete evalue dans cette etude pour un large (28km super(2)) canal du systeme de refroidissement (CCS) d'une centrale hydroelectrique de production d'energie du sud de la Floride, Etats-Unis. Une coupe transversale en deux dimensions a ete utilisee pour evaluer les effets des heterogeneites hydrauliques, de la salinite du canal de refroidissement, du transport de chaleur et de la geometrie du canal sur la salinisation d'un aquifere et les mouvements a l'interface eau douce-eau salee. Quatre configurations de conductivite hydraulique, avec des valeurs variant de plusieurs ordres de grandeur, ont ete evaluees avec un modele. Pour toutes les conditions evaluees, la salinisation de l'aquifere a commence par la formation de doigts de forte densite et salinite descendant vers le fond de l'aquifere de 30m d'epaisseur. Les doigts sales ont atteint le fond de l'aquifere apres un temps variant de quelques jours a 5 ans environ dans le cas des plus faibles conductivites hydrauliques. La salinisation de l'aquifere a continue apres que les doigts sales aient atteint le fond de l'aquifere et aient fusionnes par des mouvements lateraux en dehors du site. Les resultats du modele montrent que la salinisation de l'aquifere a ete tres sensible a l'heterogeneite de l'aquifere et egalement a la salinite, temperature et configuration du CCS.

The pressure gradient that generates the prism acts on the subterranean estuary. Analytical models for the groundwater tidal prism and associated benthic flux are presented. The prism and flux are shown to be directly proportional to porosity, tidal amplitude, and the length of the groundwater wave; flux is inversely proportional to tidal period. The duration of discharge flux exceeds the duration of recharge flux over one tidal period; and discharge flux continues for some time following low tide. Models compare favorably with laboratory observations and are applied to a South Atlantic Bight study area, where tide generates an 11-m super(3) groundwater tidal prism per m of shoreline, and drives 81m super(3)s super(ȡ 2; 1) to the study area, which describes 23% of an observational estimate. In a marine water body, the discharge component of any oscillatory benthic water flux is submarine groundwater discharge. Benthic flux transports constituents between groundwater and surface water, and is a process by which pollutant loading and saltwater intrusion may occur in coastal areas.Original Abstract: Le prisme de maree d'eaux souterraine est defini comme le volume brut d'eau qui inonde le milieu poreux, contraint par une oscillation de maree de la masse d'eau de surface. Le gradient de pression qui engendre le prisme agit sur l'estuaire souterrain. Des modeles analytiques du prisme de maree d'eaux souterraine et du flux benthique associe sont presentes. Il est montre que prisme et flux sont directement proportionnels a la porosite, a l'amplitude de la maree et a la longueur de la vague d'eau souterraine; le flux est inversement proportionnel a la periode de la maree. La duree du flux de vidange excede celle du flux de recharge au cours d'un cycle de maree ; et un flux de vidange se produit encore quelque temps apres la maree basse. La confrontation des modeles aux observations de laboratoire est favorable. Ces modeles sont appliques a une zone d'etude de la Baie Atlantique Sud ou la maree genere un prisme de maree d'eau souterraine de 11m super(3) par metre de cote, et pousse 81m super(3)s super(ȡ 2; 1) vers la zone d'etude, ce qui rend compte de 23% d'une estimation issue de l'observation. Dans une masse d'eau marine, la composante de vidange d'un flux oscillatoire d'eau benthique est une vidange sous-marine d'eau souterraine. Le flux benthique transporte des elements entre eaux souterraines et eaux de surface: il s'agit d'un processus par lequel pollution et intrusion d'eau de mer en zone cotiere peuvent se produire.

In this paper, we discuss characteristics of ecological theory and some of the challenges for proper specification of theoretical ideas in structural equation models (SE models). In our presentation, we describe some of the requirements for classical latent variable models in which observed variables (indicators) are interpreted as the effects of underlying causes. We also describe alternative model specifications in which indicators are interpreted as having causal influences on the theoretical concepts. We suggest that this latter nonclassical specification (which involves another variable type--the composite) will often be appropriate for ecological studies because of the multifaceted nature of our theoretical concepts. In this paper, we employ the use of meta-models to aid the translation of theory into SE models and also to facilitate our ability to relate results back to our theories. We demonstrate our approach by showing how a synthetic theory of grassland biodiversity can be evaluated using SEM and data from a coastal grassland. In this example, the theory focuses on the responses of species richness to abiotic stress and disturbance, both directly and through intervening effects on community biomass. Models examined include both those based on classical forms (where each concept is represented using a single latent variable) and also ones in which the concepts are recognized to be multifaceted and modeled as such. To address the challenge of matching SE models with the conceptual level of our theory, two approaches are illustrated, compositing and aggregation. Both approaches are shown to have merits, with the former being preferable for cases where the multiple facets of a concept have widely differing effects in the system and the latter being preferable where facets act together consistently when influencing other parts of the system. Because ecological theory characteristically deals with concepts that are multifaceted, we expect the methods presented in this paper will be useful for ecologists wishing to use SEM.

We used viral hemorrhagic septicemia virus (VHSV) and a laboratory stock of Pacific herring Clupea pallasii to investigate the kinetics of viral shedding and its effect on disease transmission and host mortality. Outbreaks of acute disease, accompanied by mortality and viral shedding, were initiated after waterborne exposure of herring to concentrations of VHSV as low as 10 super(1) plaque-forming units (pfu) ml super(-1). Shed virus in flow-through tanks was first detected 4 to 5 d post-exposure, peaked after 6 to 10 d, and was no longer detected after 16 d. Shedding rates, calculated from density, flow and waterborne virus titer reached 1.8 to 5.0 x 10 super(8) pfu fish super(-1) d super(-1). Onset of viral shedding was dose-dependent and preceded initial mortality by 2 d. At 21 d, cumulative mortality in treatment groups ranged from 81 to 100% and was dependent not on challenge dose, but on the kinetics and level of viral shedding by infected fish in the tank. Possible consequences of the viral shedding and disease kinetics are discussed in the context of epizootic initiation and perpetuation among populations of wild Pacific herring.

We used historic and recent data on unionids (from 1987 to 2003) and hydraulic conditions at 438 sample locations over a 38-km reach of the Upper Mississippi River (Navigation Pool 8) to compare the distribution of unionids with different shell morphologies. We evaluated whether sculptured, thick-shelled (STK) species would be found in areas with higher velocity and shear stress, compared to nonsculptured, thin-shelled (NSTN) species. We used classification trees to model the presence and absence of STK and NSTN species to determine which variables were most likely to predict their distribution. Candidate predictor variables included sampling gear, field substrate, water depth (bathymetry), slope, velocity, shear stress and Froude number under low, moderate and high discharges. Our models predicted that STK mussels would occupy a larger portion of the total aquatic area in this reach of the river than NSTN mussels. However, our data demonstrated that NSTN species used areas of higher shear stress and velocity than STK species, but were also present in backwaters with low energy, thus rejecting our hypothesis. The presence of NSTN species over a wide range of shear stress and velocity was probably due to the wide array of life histories displayed within this guild. Overall, these results are consistent with the flow refuge concept in which unionids are more prevalent in areas with low to moderate hydraulic stresses, regardless of shell morphology, and demonstrate the importance of incorporating abiotic and biotic variables into predictive models.

Key difficulties include managing an array of biophysical and socioeconomic processes across multiple spatial and temporal scales, and acquiring and utilizing empirical data to support the analysis of those processes. The Southeastern and Pacific Northwest regions of the United States, two heavily forested regions with significant forest industries, are examined in the context of these foundational elements. Geographic setting fundamentally affects both the primary land cover (forest) in the two regions, and the structure and form of land use (forestry). Land-use histories of the regions can be used to parameterize land-use models, validate model performance, and explore land-use scenarios. Drivers of change in the two regions are many and varied, with issues of scale and complexity posing significant challenges. Careful scenario development can be used to simplify process-based land-use models, and can improve our ability to address specific research questions. The successful modeling of land-use change in these two areas requires integration of both top-down and bottom-up drivers of change, using scenario frameworks to both guide and simplify the modeling process. Modular approaches, with utilization and integration of existing process models, allow regional land-use modelers the opportunity to better represent primary drivers of land-use change. However, availability of data to represent driving forces remains a primary obstacle.

As such, it is important to evaluate the impacts that such actions may have on both target and non-target species within a region. Understanding how species richness and composition differ as a result of management treatments can help determine potential ecological consequences. Yet it is difficult to estimate richness because traditional sampling approaches detect species at variable rates and some species are never observed. We present a framework for assessing management actions on biodiversity using a multi-species hierarchical model that estimates individual species occurrences, while accounting for imperfect detection of species. Our model incorporates species-specific responses to management treatments and local vegetation characteristics and a hierarchical component that links species at a community-level. This allows for comprehensive inferences on the whole community or on assemblages of interest. Compared to traditional species models, occurrence estimates are improved for all species, even for those that are rarely observed, resulting in more precise estimates of species richness (including species that were unobserved during sampling). We demonstrate the utility of this approach for conservation through an analysis comparing bird communities in two geographically similar study areas: one in which white-tailed deer (Odocoileus virginianus) densities have been regulated through hunting and one in which deer densities have gone unregulated. Although our results indicate that species and assemblage richness were similar in the two study areas, point-level richness was significantly influenced by local vegetation characteristics, a result that would have been underestimated had we not accounted for variability in species detection.

This will precipitate ecological shifts as the ranges of species change in response to new climates. During this shift, rapid-colonizing species should increase, whereas slow-colonizing species will at first decrease, but eventually become reestablished in their new range. This successional process has been estimated to require from 100 to over 300 years in small areas, under a stable climate, with a nearby seed source. How much longer will it require on a continental scale, under a changing climate, without a nearby seed source? I considered this question through an examination of the response of fossil plant assemblages from the Grand Canyon, Arizona, to the most recent rapid warming of similar magnitude that occurred at the start of the Holocene, 11,700 years ago. At that time, temperatures in southwestern North America increased about 4 C over less than a century. Grand Canyon plant species responded at different rates to this warming climate. Early-successional species rapidly increased, whereas late-successional species decreased. This shift persisted throughout the next 2700 years. I found two earlier, less-extreme species shifts following rapid warming events around 14,700 and 16,800 years ago. Late-successional species predominated only after 4000 years or more of relatively stable temperature. These results suggest the potential magnitude, duration, and nature of future ecological changes and have implications for conservation plans, especially those incorporating equilibrium assumptions or reconstituting past conditions. When these concepts are extended to include the most rapid early-successional colonizers, they imply that the recent increases in invasive exotics may be only the most noticeable part of a new resurgence of early-successional vegetation. Additionally, my results challenge the reliability of models of future vegetation and carbon balance that project conditions on the basis of assumptions of equilibrium within only a century. Respuesta de la Vegetacion al Calentamiento en el Holoceno Temprano como un Analogo para Cambios Actuales y FuturosResumen: Se proyecta que las temperaturas en el suroeste de Norte America incrementen 3.5 a 4 C en los proximos 60-90 anos. Esto precipitara cambios ecologicos a medida que cambien los rangos de las especies como respuesta a los climas nuevos. Durante este cambio, las especies colonizadoras rapidas deberan incrementar, mientras que las especies colonizadoras lentas primero decreceran, pero eventualmente se restableceran en su nuevo rango. Se ha estimado que este proceso sucesional requiere de 100 a mas de 300 anos en areas pequenas, con clima estable, con una fuente de semillas cercana. [iquest]Cuanto tiempo mas se requerira en una escala continental, bajo clima cambiante, sin una fuente de semillas cercana? Considere esta pregunta examinando la respuesta de ensambles de plantas fosiles del Gran Canon, Arizona, al calentamiento rapido de magnitud similar mas reciente que ocurrio al principio del Holoceno, hace 11,700 anos. En ese tiempo, las temperaturas en el suroeste de Norte America incrementaron casi 4 C en menos de un siglo. Las especies de plantas del Gran Canon respondieron a este aumento de temperatura de tasas diferentes. Las especies sucesionales tempranas incrementaron rapidamente, mientras que las sucesionales tardias decrecieron. Este cambio persistio durante los siguientes 2700 anos. Encontre dos cambios previos, menos extremos, despues de eventos de calentamiento rapido hace 14,700 y 16,800 anos. Las especies sucesionales tardias predominaron solo despues de 4000 o mas anos de temperatura relativamente estable. Estos resultados sugieren la potencial magnitud, duracion y naturaleza de cambios ecologicos futuros y tienen implicaciones para los planes de conservacion, especialmente los que incorporan suposiciones de equilibrio o que reconstruyen condiciones pasadas. Cuando estos conceptos son extendidos para incluir a los colonizadores sucesionales tempranos mas rapidos, implican que los incrementos recientes de invasores exoticos pueden ser solo la parte mas notable de una nueva resurgencia de vegetacion sucesional temprana. Adicionalmente, mis resultados desafian la confiabilidad de los modelos de vegetacion futura y balance de carbonos que proyectan condiciones con base en suposiciones de equilibrio durante solo un siglo.

AN - 734256649; 19809875 AB - In 2004, spotted sandpipers (Actitis macularia) were studied on the Hudson River near Fort Edward south to New Baltimore, NY and on two river drainages that flow into the Hudson River. Concentrations of 28 organochlorine pesticides, 160 polychlorinated biphenyl (PCB) congeners, and 17 dioxin and furan (PCDD-F) congeners were quantified in eggs collected on and off the Hudson River. The pattern of organochlorine pesticides and PCDD-F congeners did not differ significantly between eggs collected on and off the Hudson River. In contrast, the pattern of PCB congeners differed significantly between the Hudson River and other rivers. Total PCBs were significantly greater in eggs from the Hudson River (geometric mean = 9.1 microg PCBs/g wet weight) than from the other two rivers (0.6 and 0.6 microg PCBs/g wet weight). Seven of 35 (20%) eggs exceeded 20 microg PCBs/g wet weight, the estimated threshold for reduced hatching in tree swallows (Tachycineta bicolor) and some raptor species; the maximum concentration was 72.3 microg PCBs/g wet weight. Models that predicted nest survival and egg success (the proportion of eggs hatching in a clutch if at least one egg hatched) as functions of contaminant levels were poorly distinguished from models that presumed no such associations. While small sample size could have contributed to the inability to distinguish among contaminant and no toxicant models, we cannot rule out the possibility that contaminant concentrations on the Hudson River were not sufficiently high to demonstrate a relationship between contaminant concentrations and reproductive success.

AN - 733556595; 19659451 AB - Criteria to protect aquatic life are intended to protect diverse ecosystems, but in practice are usually developed from compilations of single-species toxicity tests using standard test organisms that were tested in laboratory environments. Species sensitivity distributions (SSDs) developed from these compilations are extrapolated to set aquatic ecosystem criteria. The protectiveness of the approach was critically reviewed with a chronic SSD for cadmium comprising 27 species within 21 genera. Within the data set, one genus had lower cadmium effects concentrations than the SSD fifth percentile-based criterion, so in theory this genus, the amphipod Hyalella, could be lost or at least allowed some level of harm by this criteria approach. However, population matrix modeling projected only slightly increased extinction risks for a temperate Hyalella population under scenarios similar to the SSD fifth percentile criterion. The criterion value was further compared to cadmium effects concentrations in ecosystem experiments and field studies. Generally, few adverse effects were inferred from ecosystem experiments at concentrations less than the SSD fifth percentile criterion. Exceptions were behavioral impairments in simplified food web studies. No adverse effects were apparent in field studies under conditions that seldom exceeded the criterion. At concentrations greater than the SSD fifth percentile, the magnitudes of adverse effects in the field studies were roughly proportional to the laboratory-based fraction of species with adverse effects in the SSD. Overall, the modeling and field validation comparisons of the chronic criterion values generally supported the relevance and protectiveness of the SSD fifth percentile approach with cadmium.

Along the west coast of North America, winter dieoffs of fulmars may be increasing in frequency and magnitude, the most severe on record being a wreck that peaked in October-November 2003. We deployed satellite transmitters on fulmars from the four main Alaska colonies and tracked individuals for up to 2 years. Fulmars from Hall Island (northern Bering Sea) moved to Russian coastal waters after breeding, while Pribilof Island fulmars (southeastern Bering Sea) remained relatively sedentary year-round. Birds from Chagulak Island (eastern Aleutians) preferred passes between the Aleutian Islands in winter or foraged widely over deep waters of the central Bering Sea and North Pacific. Fulmars from the Semidi Islands (western Gulf of Alaska) migrated directly to waters of the California Current. Individuals from St. George Island (Pribilofs) and Chagulak were consistent in the places that they visited in two successive winters. The Pribilof Islands population is most affected by winter longlining for groundfish, whereas the Semidi Islands colony sustains most of the natural mortality that occurs off Washington, Oregon, and California.Original Abstract: La mortalite d'oiseaux marins associee a la peche a la palangre dans l'est de la mer de Bering se produit principalement de septembre a mai et les fulmars boreaux (Fulmarus glacialis) constituent la majorite (60 %) de la peche accessoire.

Nous avons muni d'emetteurs satellites des fulmars provenant des quatre principales colonies de l'Alaska et nous avons suivi les individus pendant jusqu'a 2 ans. Les fulmars de l'ile Hall (nord de la mer de Bering) se deplacent vers les eaux cotieres russes apres la reproduction, alors que les fulmars des iles Pribilof (sud-est de la mer de Bering) restent relativement sedentaires a l'annee longue.

Modeled seismic sources include gridded historical seismicity, subduction-interface and strike-slip faults with known slip rates, and two broad zones of crustal extension with seismicity rates constrained by GPS geodesy. We use attenuation relations from western North American and worldwide data, as well as a Caribbean-specific relation. Results are presented as maps of peak ground acceleration and 0.2- and 1.0-second spectral response acceleration for 2% and 10% probabilities of exceedance in 50 years (return periods of about 2,500 and 500 years, respectively).

The volume of water that diffuses within an egg is most likely determined by (1) the difference in ionic concentration between the egg and the water that surrounds it and (2) the elasticity of the egg membrane. Prior observations suggest that silver carp eggs may swell and burst in soft waters. If water hardness affects silver carp reproductive success in nonnative ecosystems, this abiotic factor could limit silver carp distribution or abundance. In this study, we tested the effect of water hardness on silver carp egg enlargement and hatching success. Groups of newly fertilized silver carp eggs were placed in water at one of five nominal water hardness levels (50, 100, 150, 200, or 250 mg/L as CaCO sub(3)) for 1 h to harden (absorb water after fertilization). Egg groups were then placed in separate incubation vessels housed in two recirculation systems that were supplied with either soft (50 mg/L as CaCO sub(3)) or hard (250 mg/L as CaCO sub(3)) water to evaluate hatching success. Tests were terminated within 24 h after viable eggs had hatched. Eggs that were initially placed in 50-mg/L water to harden were larger (i.e., swelled more) and had a greater probability of hatch than eggs hardened in other water hardness levels. Unlike the effect of water hardness during egg hardening, the water hardness during incubation appeared to have no effect on egg hatching success. Our research suggests that water hardness may not be a limiting factor in the reproduction, recruitment, and range expansion of silver carp in North America.

Therefore, we evaluated walleye spawning success in Dutch Hollow Brook, a tributary of Owasco Lake, to determine whether early survival limited recruitment. Spawning success during spring 2006 and 2007 was evaluated by estimating egg densities from samples collected in the lower 725 m of the stream. Environmental variables were also recorded to characterize the selected spawning habitat. Drift nets were set downstream of the spawning section to assess egg survival and larval drift. We estimated that 162,596 larvae hatched in 2006. For 2007, we estimated that 360,026 eggs were deposited, with a hatch of 127,500 larvae and hatching success of 35.4%. Egg density was significantly correlated to percent cover, substrate type, and depth : velocity ratio. Two sections had significantly higher egg deposition than other areas. Adult spawning walleyes selected shallow, slow habitats with some cover and gravel substrate in the accessible reaches of Dutch Hollow Brook. Our results show that walleyes found suitable spawning habitat in Dutch Hollow Brook and that egg and larval development does not appear to limit natural reproduction.

Assessing hydrologic condition requires that we quantify the attributes of the flow regime that would be expected in the absence of anthropogenic modifications. The objective of this study was to evaluate whether selected streamflow characteristics could be predicted at regional and national scales using geospatial data. Long-term, gaged river basins distributed throughout the contiguous US that had streamflow characteristics representing least disturbed or near pristine conditions were identified. Thirteen metrics of the magnitude, frequency, duration, timing and rate of change of streamflow were calculated using a 20-50 year period of record for each site. We used random forests (RF), a robust statistical modelling approach, to develop models that predicted the value for each streamflow metric using natural watershed characteristics. We compared the performance (i.e. bias and precision) of national- and regional-scale predictive models to that of models based on landscape classifications, including major river basins, ecoregions and hydrologic landscape regions (HLR). For all hydrologic metrics, landscape stratification models produced estimates that were less biased and more precise than a null model that accounted for no natural variability. Predictive models at the national and regional scale performed equally well, and substantially improved predictions of all hydrologic metrics relative to landscape stratification models. Prediction error rates ranged from 15 to 40%, but were <=25% for most metrics. We selected three gaged, non-reference sites to illustrate how predictive models could be used to assess hydrologic condition. These examples show how the models accurately estimate pre-disturbance conditions and are sensitive to changes in streamflow variability associated with long-term land-use change. We also demonstrate how the models can be applied to predict expected natural flow characteristics at ungaged sites.

We investigated behavioural responses of spawning chum salmon to increased water velocities associated with experimental increases in tailwater elevation using acoustic telemetry and a dual-frequency identification sonar. Chum salmon primarily remained near their redds at base tailwater elevations (3.5m above mean sea level), but displayed different movement and behavioural responses as elevations were increased to either 4.1 or 4.7m for 8-h periods. When velocities remained suitable (<0.8m s-1) during elevated-tailwater tests, female chum salmon remained near their redds but exhibited reduced digging activity as water velocities increased. However, when velocities exceeded 0.8ms-1, the females that remained on their redds exhibited increased swimming activity and digging virtually ceased. Female and male chum salmon that left their redds when velocities became unsuitable moved mean distances ranging from 32 to 58m to occupy suitable velocities, but returned to their redds after tailwaters returned to base levels. Spawning events (i.e. egg deposition) were observed for five of nine pairs of chum salmon following tests indicating any disruptions to normal behaviour caused by elevated tailwaters were likely temporary. We believe a chum salmon's decision to either remain on, or leave, its redd during periods of unsuitably high water velocities reflects time invested in the redd and the associated energetic costs it is willing to incur.

Przewalskium is monotypic. This species is a high-elevation specialist endemic to the eastern Tibetan Plateau where it inhabits relatively open hills and mountains with a mosaic of forest edges, meadows, and shrublands. Populations of P. albirostre are highly fragmented and vulnerable because of exploitation and competition with domestic livestock of pastoralists. There have been no systematic efforts to estimate the total number of extant P. albirostre, and it is considered Vulnerable by the International Union for Conservation of Nature and Natural Resources.

13268638 AB - Land use activities can have a major impact on the temporal trends and spatial patterns of regional land-atmosphere exchange of carbon. Federal lands generally have substantially different land management strategies from surrounding areas, and the carbon consequences have rarely been quantified and assessed. Using the Fort Benning Installation as a case study, we used the General Ensemble biogeochemical Modeling System (GEMS) to simulate and compare ecosystem carbon sequestration between the U.S. Army's Fort Benning and surrounding areas from 1992 to 2050. Our results indicate that the military installation sequestered more carbon than surrounding areas from 1992 to 2007 (76.7 vs 18.5 g C m-2 yr-1), and is projected to continue sequestering more carbon from 2008 to 2050 (75.7 vs 25.6 g C m-2 yr-1), mostly because of the proactive management approaches adopted on military training lands. Our results suggest that federal lands might play a positive and important role in sequestering and conserving atmospheric carbon because some anthropogenic disturbances (e.g., urbanization, forest harvesting, and agriculture) can be minimized or prevented on federal lands.

This has created a condition where upper reaches of the river that formerly provided valuable cold-water rearing habitat for juvenile salmonids have been significantly impaired by the lack of flow (Downie, et al., 2002). Because the upper portions of the river channel are dominated by bedrock, it is unlikely that channel aggradation or increased subsurface flow has contributed to the observed low-flow condition in the upper basin. Nor does annual precipitation appear to have decreased significantly during this period (Klein 2004). Thus forcing two questions. Where has the water gone, given that total annual precipitation amounts have not changed significantly? And, what, if anything can be done to increase late dry-season base flow? Land use changes that have occurred over the past century have probably exacerbated low-flow conditions, including increased diversion of surface water, increased evaporation from manmade ponds, compaction of soils from logging and ranching activities, construction of impervious surfaces, draining of wetlands, and construction of roads. However, the majority of these changes occurred several decades ago, and thus, are probably not primarily responsible for the significant reductions in low-flow observed since 2000. Widespread timber harvest resulted in a vast network of logging roads, significant erosion, and compaction of surface soils, but most of this activity occurred from the 1950s until the 1970s. Although there has been some additional residential development in the watershed, there are no diversions in upper portions of the watershed and reductions in flow are observed even there. This leaves increased evapotranspiration by the forest and a changed climate regime as probable causes for the recent decreases in flow. Both altered forest stand composition and climate change have some degree of anthropogenic causation and, as with many other river systems, it seems likely that cumulative anthropogenic changes to the watershed are the primary cause for impaired water quality and degraded aquatic habitat. This project was undertaken to help determine if hydraulic modifications in the upper watershed could potentially increase the late summer base flow to help mitigate the observed drying up of this watershed.

When standard raster filter operations are applied to digital terrain data, important ridge tops and valley edges are blurred, altering the characteristic shape of these features in the resulting shaded relief. This paper introduces Terrain Sculptor, a software application that prepares generalized terrain models for relief shading. The application uses a generalization methodology based on a succession of raster operations. Curvature coefficients detect and accentuate important relief features. Terrain Sculptor offers a graphical user interface to adjust the algorithm to various scales and terrain resolutions. The freeware application is available at http://www.terraincartography.com/terrainsculptor/.

The aim of this foldable map with topography is to support an interdisciplinary research network focusing on the cultural history of the western Himalayas starting in the eighth century. In this research network, cartography and geography fulfill a mediating role between the disciplines of art history, numismatics, Buddhist philosophy, and Tibetan and Sanskrit philology. The map's goal is to facilitate scientific work and interdisciplinary collaboration both in the office and out in the field. In addition to the printed version, the map is available for download to the general public through a Web-based cartographic information system. Topographic data was compiled from a variety of sources--starting with maps originally surveyed by the colonial British and ending with satellite imagery. Production involved ArcGIS and Natural Scene Designer for initial data preparation and Adobe Photoshop and Illustrator for final map compilation.

I derived habitat models and mapped predicted abundance for the Golden-winged Warbler (Vermivora chrysoptera), a species of high conservation concern, using bird counts, environmental variables, and hierarchical models applied at multiple spatial scales. My aim was to understand habitat associations at multiple spatial scales and create a predictive abundance map for purposes of conservation planning for the Golden-winged Warbler. My models indicated a substantial influence of landscape conditions, including strong positive associations with total forest composition within the landscape. However, many of the associations I observed were counter to reported associations at finer spatial extents; for instance, I found Golden-winged Warblers negatively associated with several measures of edge habitat. No single spatial scale dominated, indicating that this species is responding to factors at multiple spatial scales. I found Golden-winged Warbler abundance was negatively related with Blue-winged Warbler (Vermivora cyanoptera) abundance. I also observed a north-south spatial trend suggestive of a regional climate effect that was not previously noted for this species. The map of predicted abundance indicated a large area of concentrated abundance in west-central Wisconsin, with smaller areas of high abundance along the northern periphery of the Prairie Hardwood Transition. This map of predicted abundance compared favorably with independent evaluation data sets and can thus be used to inform regional planning efforts devoted to conserving this species.Original Abstract: La conservation requiert l'identification des parametres d'habitat pertinents et l'identification de lieux geographiques ou l'amenagement du territoire peut bonifier l'habitat des especes hautement prioritaires. J'ai developpe des modeles d'utilisation de l'habitat et j'ai cartographie l'abondance prevue de la Paruline a ailes dorees (Vermivora chrysoptera), espece dont le statut de conservation est considere comme hautement preoccupant, en utilisant des denombrements d'oiseaux, des variables environnementales et des modeles hierarchiques appliques a de multiples echelles spatiales. Mon but etait de comprendre les associations entre cette espece et son habitat a plusieurs echelles et de creer une carte d'abondance prevue afin de planifier la conservation de la Paruline a ailes dorees. Mes modeles indiquent que le contexte du paysage a une influence substantielle, incluant de fortes relations positives avec le couvert forestier total. Cependant, plusieurs des associations que j'ai observees allaient a l'encontre de celles qui sont rapportees a des resolutions spatiales plus fines; par exemple, j'ai trouve que les Parulines a ailes dorees etaient reliees negativement a plusieurs variables caracterisant l'habitat de lisiere. Aucune echelle spatiale ne dominait, indiquant que cette espece repond a des facteurs qui agissent a plusieurs echelles spatiales. J'ai observe une relation negative entre l'abondance de la Paruline a ailes dorees et celle de la Paruline a ailes bleues (Vermivora cyanoptera). J'ai aussi observe un gradient nord-sud qui suggere un effet climatique regional qui n'avait pas encore ete rapporte chez cette espece. La carte d'abondance prevue indique une grande concentration dans le centre-ouest du Wisconsin, ainsi que d'autres zones de forte abondance le long de la peripherie nord de la zone de transition entre la prairie et la foret feuillue. Cette carte d'abondance prevue se compare favorablement a des jeux de donnees independants et peut done etre utilisee dans le cadre des initiatives regionales visant a conserver cette espece.

For the first time since the original design, the Bureau of Reclamation's Building Seismic Safety Program (Program) has conducted a structural seismic evaluation of the both the Nevada and Arizona Powerplant superstructures and the Central Portion superstructure. These structures consist of multi-story reinforced concrete and structural steel systems built integrally with the downstream face of the dam and canyon walls. This paper illustrates the Program's usage of ASCE 31 and the finite element modeling techniques employed during the Powerplant evaluation. The Bureau of Reclamation owns 67 powerplants and over 200 pumping plants that are located throughout the western United States. The Program is tasked with assessing the structural and nonstructural seismic risks in these plants and providing recommendations and/or considerations for mitigating identified risks to the decision-makers for the facilities.

Stream temperature will be influenced not only by the predicted increases in average air temperature, but also by changes in baseflow due to changes in precipitation patterns and amounts. In order to evaluate future stream temperature and flow regimes in Wisconsin, we have integrated two existing models in order to generate a water temperature time series at a regional scale for thousands of stream reaches where site-specific temperature observations do not exist. The approach uses the US Geological Survey (USGS) Soil-Water-Balance (SWB) model, along with a recalibrated version of an existing artificial neural network (ANN) stream temperature model. The ANN model simulates stream temperatures on the basis of landscape variables such as land use and soil type, and also includes climate variables such as air temperature and precipitation amounts. The existing ANN model includes a landscape variable called DARCY designed to reflect the potential for groundwater recharge in the contributing area for a stream segment. SWB tracks soil-moisture and potential recharge at a daily time step, providing a way to link changing climate patterns and precipitation amounts over time to baseflow volumes, and presumably to stream temperatures. The recalibrated ANN incorporates SWB-derived estimates of potential recharge to supplement the static estimates of groundwater flow potential derived from a topographically based model (DARCY). SWB and the recalibrated ANN will be supplied with climate drivers from a suite of general circulation models and emissions scenarios, enabling resource managers to evaluate possible changes in stream temperature regimes for Wisconsin.

Four sites were investigated on Long Island, New York, characterized by groundwater contaminated with gasoline and fuel oxygenates that ultimately discharge to fresh, brackish, or saline surface water. For each site, contaminated groundwater discharge zones were delineated using pore water geochemistry data from 15 feet (4.5 m) beneath the bottom of the surface water body in the hyporheic zone and seepage-meter tests were conducted to measure discharge rates. These data when combined indicate that MTBE, TBA, and TAME concentrations in groundwater discharge in a 5-foot (1.5-m) thick section of the hyporheic zone were attenuated between 34% and 95%, in contrast to immeasurable attenuation in the shallow aquifer during contaminant transport between 0.1 and 1.5 miles (0.1 to 2.4 km). The attenuation observed in the hyporheic zone occurred primarily by physical processes such as mixing of groundwater and surface water. Biodegradation also occurred as confirmed in laboratory microcosms by the mineralization of U- 14C-MTBE and U-14C-TBA to 14CO2 and the novel biodegradation of U- 14C-TAME to 14CO2 under oxic and anoxic conditions. The implication of fuel oxygenate attenuation observed in diverse hyporheic zones suggests an assessment of the hyporheic zone attenuation potential (HZAP) merits inclusion as part of site assessment strategies associated with monitored or engineered attenuation.

Hoover Dam was one of the first multipurpose dams constructed by the federal government. Lake Mead is the largest reservoir in the United States by volume (3.5479 t 1010 m3 at full pool) and is second only to Lake Powell in surface area (637.05 km2). Water from Lake Mead is used for municipal and industrial purposes and irrigation water by approximately 25,000,000 people. The Colorado River provides approximately 97% of the inflow, with the remainder coming primarily from Las Vegas Wash and the Virgin and Muddy rivers. Flow in Las Vegas Wash more than doubled over the past 30 years as a result of the rapid population growth in Las Vegas. Lake surface elevations have dropped by about 40 m since 1999 as a result of extended drought and increasing water demands brought about by population growth. This elevation change impacted water quality and recreation and is just one of many management challenges facing the lake. The discovery of adult quagga mussels (Dreissena rostriformis bugensis) in Lake Mead in February 2007 created infrastructure management problems and raised concerns about lake biology and water quality. The impacts of this invasion are still under investigation. This manuscript provides information on the history of Lake Mead, as well as descriptions of lake and watershed characteristics, hydrology, water quality, fisheries, and recreation that lake managers can use to guide future assessment and management of Lake Mead.

The R-channel theory provided for the first time a physically based conceptual model of water flow through glaciers. The theory also marks the emergence of glacier hydrology as a glaciological discipline with goals and methods distinct from those of surface-water hydrology.

The objectives of this sampling program were to (1) assess the nonpoint-source chemical loading potential to ephemeral and perennial drainage basins from uranium waste dumps and (2) assess potential effects on human health due to recreational activities on and around uranium waste dumps on Bureau of Land Management property. Uranium waste-dump samples were collected using solid-phase sampling protocols. After collection, solid-phase samples were homogenized and extracted in the laboratory using a leaching procedure. Filtered (0.45 micron) water samples were obtained from the field leaching procedure and were analyzed for major and trace elements at the Inductively Coupled Plasma-Mass Spectrometry Metals Analysis Laboratory at the University of Utah. A subset of the solid-phase samples also were digested with strong acids and analyzed for major ions and trace elements at the U.S. Geological Survey Geologic Division Laboratory in Denver, Colorado. For the initial ranking of chemical loading potential for uranium waste dumps, results of leachate analyses were compared with existing aquatic-life and drinking-water-quality standards. To assess potential effects on human health, solid-phase digestion values for uranium were compared to soil screening levels (SSL) computed using the computer model RESRAD 6.5 for a probable concentration of radium. One or more chemical constituents exceeded aquatic life and drinking-water-quality standards in approximately 64 percent (29/45) of the leachate samples extracted from uranium waste dumps. Most of the uranium waste dump sites with elevated trace-element concentrations in leachates were located in Red Canyon. Approximately 69 percent (31/45) of the strong acid digestible soil concentration values were greater than a calculated SSL. Uranium waste dump sites with elevated leachate and total digestible concentrations may need to be further investigated to determine the most appropriate remediation method.

Due to inclement weather, this survey was performed in two stages: early September 2007 and September-October 2008. The total surveyed area of 241,585 acres includes an approximately 100-m-wide buffer zone around the Park to ensure complete coverage and adequate point densities at survey edges. Final results averaged 5.73 laser first return points/m (super 2) over forested and high-elevation terrain, with a vertical accuracy of 3.7 cm on bare road surfaces and mean relative accuracy of 11 cm, based on comparisons between flightlines. Bare-earth topography, as developed by the contractor, is included in this release. A map of the 2007-2008 limits of glaciers and perennial snowfields was developed by digitizing 1:2,000 to 1:5,000 slope and shaded-relief images derived from the LiDAR topography. Edges of snow and exposed ice are readily seen in such images as sharp changes in surface roughness and slope. Ice mantled by moraine can be distinguished by the moraine's distinctly high roughness due to ice motion and melting, local exposures of smooth ice, and commonly by the presence of crevasses and shear boundaries. A map of the 1970 limits of ice and perennial snow was also developed by digitizing the snow and ice perimeters as depicted on the hydrologic separates used to produce the 1:24,000 topographic maps of the Mount Rainier region. These maps, produced in 1971, were derived from September 1970 aerial photographs. Boundaries between adjacent glacier systems were estimated and mapped from drainage divides, including partly emergent rock ridges, lines of diverging slope, and medial moraines. This data release contains the bare-earth LiDAR data as an ESRI grid file (DS549-Rainier_LiDAR.zip), the glacial limits derived from the USGS 1970 aerial photographs of the Mount Rainier vicinity as a shapefile, and the glacial limits derived from the 2007 to 2008 LiDAR survey as a shapefile (both shapefiles contained in DS549-Glacial_Limits.zip). These geospatial data files require GIS software for viewing. JF - U. S.

Those that the Bureau of Reclamation (Reclamation) has come across recently are: The Texas Gulf Coast where brackish surface or groundwater is available for much of the year but only seawater is available during dry seasons; . South central California where the character of the irrigation drainage water changes with the intensity of irrigation; . Inland desert areas where the composition of brackish surface and groundwater is significantly different when augmented with storm water. Reclamation assisted the US Office of Naval Research in development and demonstration of the Expeditionary Unit Water Purifier system which can produce 378 m[super]3/day (100,000 gal/day) of potable water from any liquid source water up to 60 g/L TDS under 35 degree C. The system was tested under the Environmental Technology Validation (ETV) program overseen by NSF International for the US Environmental Protection Agency (EPA). Test water sources were seawater, turbid surface water, and tertiary wastewater. As a complete system, it performed well with each source. It was only capable of 50% recovery of water however. Because of this, the system has been turned down for potential emergency applications due to the excessive loss of water. This issue occurring at the same time as the three situations mentioned above prompted a proposal to design a flexible system that could be adapted to achieve high water recovery when the feed source allows while still maintaining the capability of recovering energy when the remaining concentrate pressure allows.

With 74 ocean and Great Lakes parks stretching over more than 5,000 miles of coastline across 26 States and territories, this Servicewide Benthic Mapping Program (SBMP) is essential. This program will deliver benthic habitat maps and their associated inventory reports to NPS managers in a consistent, servicewide format to support informed management and protection of 3 million acres of submerged National Park System natural and cultural resources. The NPS and the U.S. Geological Survey (USGS) convened a workshop June 3-5, 2008, in Lakewood, Colo., to discuss the goals and develop the design of the NPS SBMP with an assembly of experts (Moses and others, 2010) who identified park needs and suggested best practices for inventory and mapping of bathymetry, benthic cover, geology, geomorphology, and some water-column properties. The recommended SBMP protocols include servicewide standards (such as gap analysis, minimum accuracy, final products) as well as standards that can be adapted to fit network and park unit needs (for example, minimum mapping unit, mapping priorities). SBMP Mapping Process. The SBMP calls for a multi-step mapping process for each park, beginning with a gap assessment and data mining to determine data resources and needs. An interagency announcement of intent to acquire new data will provide opportunities to leverage partnerships. Prior to new data acquisition, all involved parties should be included in a scoping meeting held at network scale. Data collection will be followed by processing and interpretation, and finally expert review and publication. After publication, all digital materials will be archived in a common format. SBMP Classification Scheme. The SBMP will map using the Coastal and Marine Ecological Classification Standard (CMECS) that is being modified to include all NPS needs, such as lacustrine ecosystems and submerged cultural resources. CMECS Version III (Madden and others, 2010) includes components for water column, biotic cover, surface geology, sub-benthic, and geoform. SBMP Data Archiving. The SBMP calls for the storage of all raw data and final products in common-use data formats. The concept of "collect once, use often" is essential to efficient use of mapping resources. Data should also be shared with other agencies and the public through various digital clearing houses, such as Geospatial One-Stop (http://gos2.geodata.gov/wps/portal/gos). To be most useful for managing submerged resources, the SBMP advocates the inventory and mapping of the five components of marine ecosystems: surface geology, biotic cover, geoform, sub-benthic, and water column. A complete benthic inventory of a park would include maps of bathymetry and the five components of CMECS. The completion of mapping for any set of components, such as bathymetry and surface geology, or a particular theme (for example, submerged aquatic vegetation) should also include a printed report.

Recent catastrophic shifts in Everglades landscape pattern and ecological function highlight the need to understand the feedbacks governing these ecosystems. We modeled feedback between vegetation, hydrology, and sediment transport on the basis of a decade of experimentation. Results from more than 100 simulations showed that flows just sufficient to redistribute sediment from sparsely vegetated sloughs to dense ridges were needed for an equilibrium patterned landscape oriented parallel to flow. Surprisingly, although vegetation heterogeneity typically conveys resilience, in wetlands governed by flow/sediment feedbacks it indicates metastability, whereby the landscape is prone to catastrophic shifts. Substantial increases or decreases in flow relative to the equilibrium condition caused an expansion of emergent vegetation and loss of open-water areas that was unlikely to revert upon restoration of the equilibrium hydrology. Understanding these feedbacks is critical in forecasting wetland responses to changing conditions and designing management strategies that optimize ecosystem services, such as carbon sequestration or habitat provision. Our model and new sensitivity analysis techniques address these issues and make it newly apparent that simply returning flow to predrainage conditions in the Everglades may not be sufficient to restore historic landscape patterns and processes.

In many streams, environmental disturbance and consumer identity may interact to influence benthic ecosystem structure and fu Action. We predicted that effects of two common consumers (central stonerollers (Campostoma anomalum) and Meek's crayfish (Orcotiectes meeki meeki)) in Ozark Mountain streams (Arkansas, USA) would be altered by disturbance. In stream mesocosms we crossed disturbance (simulated spate) and consumer identity (crayfish, central stonerollers, or no consumers). Stream ecosystem function was quantified as leafpack decomposition and net primary productivity (NPP). Ecosystem structure was measured as algal Chlorophyll-a, ash-free dry mass (AFDM), and chironomid density. Disturbance and interactions between disturbance and consumer identity did not sig-niflcantly affect any response variable. Chlorophyll-a, AFDM, and chironomid density were influenced by consumer identity, and effects differed between stonerollers and crayfish and with time. Crayfish and stonerollers reduced day 15 chironomid density compared with no con one fourth ¬sumer treatments. Stonerollers reduced day 30 chironomid density and day 15 periphyton abundance compared with crayfish and no consumer treatments. Crayfish increased leafpack breakdown rates above stoneroller and no consumer treatments, but NPP did not differ among consumer treatments. In this experiment, consumers bad strohger effects an benthic structure and function than the disturbance treatment.

Commonly, accompanying this sediment are contaminants such as elemental mercury and cyanide used in the gold extraction process. We show that some of the mercury-contaminated sediment created by hydraulic gold mining in the Sierra Nevada, between 1852 and 1884, ended up over 250 kilometers (km) away in San Francisco Bay; an example of the far-reaching extent of contamination from such activities. A combination of radionuclide dating, bathymetric reconstruction, and geochemical tracers were used to distinguish the hydraulic mining sediment from sediment deposited in the bay before hydraulic mining started (pre-Gold Rush sediment) and sediment deposited after hydraulic mining stopped (modern sediment). Three San Francisco Bay cores were studied as well as source material from the abandoned hydraulic gold mines and river sediment between the mines and bay. Isotopic and geochemical compositions of the core sediments show a geochemical shift in sediment deposited during the time of hydraulic mining. The geochemical shift is characterized by a decrease in epsilon Nd, total organic carbon (TOC), Sr and Ca concentrations, Ca/Sr, and Ni/Zr; and, an increase in 87Sr/86Sr, Al/Ca, Hg concentrations, and quartz/plagioclase. This shift is in the direction of the geochemical signature of sediments from rivers and goldmines in hydraulic mining areas. Mixing calculations using Nd isotopes and concentrations estimate that the hydraulic mining debris comprises up to 56% of the sediment in core sediments deposited during the time of hydraulic mining. The surface sediment of cores taken in 1990 were found to contain up to 43% hydraulic mining debris, reflecting a continuing remobilization and redistribution of the debris within the bay and transport from the watershed. Mercury concentrations in pre-Gold Rush sediment range between 0.03 and 0.08 mu g g-1. In core sediments that have characteristics of the gold deposits and were deposited during the time of hydraulic mining, mercury concentrations can be up to 0.45 mu g/g. Modern sediment (post-1952 deposition) contains mercury concentrations up to 0.79 mu g/g and is likely a mix of hydraulic mining mercury and mercury introduced from other sources.

To assess potential inundation associated with a continued acceleration of sea level rise, the highest resolution elevation data available were assembled from various sources and mosaicked to cover the land surfaces of the San Francisco Bay region. Next, to quantify extreme water levels throughout the bay, a hydrodynamic model of the San Francisco Estuary was driven by a projection of hourly water levels at the Presidio. This projection was based on a combination of climate model outputs, an empirical model, and observations, and incorporates astronomical, storm surge, El Nino, and long-term sea level rise influences. Based on the resulting data, maps of areas vulnerable to inundation were produced, corresponding to specific amounts of sea level rise and recurrence intervals, including tidal datums. These maps portray areas where inundation will likely be an increasing concern. In the North Bay, wetlands and some developed fill areas are at risk. In Central and South bays, a key feature is the landward periphery of developed areas that would be newly vulnerable to inundation. Nearly all municipalities adjacent to South Bay face this risk to some degree. For the bay as a whole, as early as mid-century under this scenario, the one-year peak event nearly equals the 100-year peak event in 2000. Maps of vulnerable areas are presented and some implications discussed. Results are available for interactive viewing and download at http://cascade.wr.usgs.gov/data/Task2b-SFBay.

Our analysis of individual growth rings in a tree core from the Mud Volcano thermal area within the caldera links a sharp similar to 25% drop in 14C to a local seismic swarm in 1978. The implied fivefold increase in CO2 emissions clearly associates swarm seismicity with upflow of magma-derived fluid and shows that pulses of magmatic CO2 can rapidly traverse the 5-km-thick brittle zone, even through Yellowstone's enormous hydrothermal reservoir. The 1978 event predates annual deformation surveys, but recognized connections between subsequent seismic swarms and changes in deformation suggest that CO2 might drive both processes.

Since the mid-1980s, this population has increased in numbers and expanded in range. However, concerns for its long-term genetic health remain because of its presumed continued isolation. To test the power of genetic methods for detecting immigrants, we generated 16-locus microsatellite genotypes for 424 individual grizzly bears sampled in the GYE during 1983-2007. Genotyping success was high (90%) and varied by sample type, with poorest success (40%) for hair collected from mortalities found greater than or equal to 1day after death. Years of storage did not affect genotyping success. Observed heterozygosity was 0.60, with a mean of 5.2 alleles/marker. We used factorial correspondence analysis (Program GENETIX) and Bayesian clustering (Program STRUCTURE) to compare 424 GYE genotypes with 601 existing genotypes from grizzly bears sampled in the Northern Continental Divide Ecosystem (NCDE) (FST = 0.096 between GYE and NCDE). These methods correctly classified all sampled individuals to their population of origin, providing no evidence of natural movement between the GYE and NCDE. Analysis of 500 simulated first-generation crosses suggested that over 95% of such bears would also be detectable using our 16-locus data set. Our approach provides a practical method for detecting immigration in the GYE grizzly population. We discuss estimates for the proportion of the GYE population sampled and prospects for natural immigration into the GYE.

After 10 years, about 10% of pellets remained within 6 cm of the surface, but >50% remained within 10 cm. We predict that spent lead pellets will eventually become unavailable to waterfowl; however, it will likely require >25 years for all pellets to exceed depths at which waterfowl species may forage.

Coastal park units chosen for the assessment included a variety of geological and physical settings along the U.S. Atlantic, Pacific, Gulf of Mexico, Gulf of Alaska, Caribbean, and Great Lakes shorelines. This research is motivated by the need to understand and anticipate coastal changes caused by accelerating sea-level rise, as well as lake-level changes caused by climate change, over the next century. The goal of these assessments is to provide information that can be used to make long-term (decade to century) management decisions. Here we analyze the results of coastal vulnerability assessments for several coastal national park units.

These studies allow water management agencies, such as the Bureau of Reclamation, to evaluate the impacts of proposed changes in a river basin system under their management and convey their findings to critical stakeholders and the general public. Planning studies typically structure an assumption of future water supply, demands, and reservoir operations and represent changes to one or a combination of these assumptions versus present conditions. Future water supply assumption or planning hydrologies are typically developed from information based on observed gauge records. Planning hydrologies based on these data assume that future conditions can be represented by the climate events of the observed past. Recent evidence has shown the observed past may not provide an adequate proxy of future climate. It is becoming increasing difficult to depend on planning hydrologies that are solely based on information provided by the recent observed past. In the Colorado River Basin, until 2007 planning studies only utilized a naturalized flow dataset that extended back to 1906. This record was built from observed records that capture the hydrologic variability observed over the last century. Though the Colorado River Basin has a "long" observed dataset, in the eyes of many practitioners the basin has been recently enduring a drought that is unprecedented in its observed record. The current drought that began in 2000 continues today producing the lowest ten year average flow in the last hundred years. This unprecedented drought has provided an excellent opportunity for Reclamation to explore alternate methods to develop planning hydrologies that go beyond dependence on the observed past. As a first step Reclamation sought to re-introduce paleo-reconstructed streamflows. These reconstructions provide a window into the distant past, significantly enhancing relevant frequency characteristics in a planning hydrology and incorporating climate information from the past one thousand years rather than just the last one hundred. Such reconstructions have been available in the Colorado River basin since 1976 but have not gained wide acceptance in planning studies. Though reconstructed streamflows provide rich information and should be incorporated in planning hydrologies, the magnitudes of reconstructed streamflow can have a high degree of uncertainty. When creating a reconstruction a regression model is fit to the observed streamflow with a collection of tree ring observations as the predictors. This fitted model is then used to estimate streamflows in the pre-observational period using the tree ring observations. The reconstructed streamflows can be sensitive to the choice of model as demonstrated by Hidalgo et al. (2000). This apparent weakness of the paleo reconstructed flow data has rendered their use in a water resources planning context questionable, despite the availability of paleo reconstructed data for many decades. Despite these apparent weaknesses, few argue about the duration and frequency of dry and wet (i.e., the hydrologic state) periods from the reconstructions. Recognizing the limitations of relying on only the instrumental record for long-term planning studies, Reclamation devised a framework to combine the long paleo reconstructed streamflow information of lower reliability with the shorter but reliable observational data. The framework blends paleoreconstructed hydrologic state (i.e., wet or dry) with instrumental records magnitudes. With these datasets the framework addresses generating simulations for planning studies with drought and surplus spells that demonstrate the persistence underlying the lengthy paleo reconstructions.

The chemical and isotopic composition of streamflow and precipitation was measured during selected local and frontal low- and high-intensity storm events and compared to the geochemical and isotopic composition of groundwater. Input for the GMB method included cation, anion, and stable isotope concentrations of surface water and groundwater, whereas input for the CMB method included continuous or point sample measurement of specific conductance. The surface water is a calcium-bicarbonate type water, which closely resembles groundwater geochemically, indicating that much of the surface water in the upper Hillsborough River basin is derived from local groundwater discharge. This discharge into the Hillsborough River at State Road 39 and at Hillsborough River State Park becomes diluted by precipitation and runoff during the wet season, but retains the calciumbicarbonate characteristics of Upper Floridan Aquifer water. Field conditions limited the application of the GMB method to low-intensity storms but the CMB method was applied to both low-intensity and high-intensity storms. The average contribution of base flow to total discharge for all storms ranged from 31 to 100 percent, whereas the contribution of base flow to total discharge during peak discharge periods ranged from less than 10 percent to 100 percent. Although calcium, magnesium, and silica were consistent markers of Upper Floridan Aquifer chemistry, their use in calculating base flow by the GMB method was limited because the frequency of point data collected in this study was not sufficient to capture the complete hydrograph from pre-event base-flow to post-event base-flow concentrations. In this study, pre-event water represented somewhat diluted groundwater. Streamflow conductivity integrates the concentrations of the major ions, and the logistics of acquiring specific conductance at frequent time intervals are less complicated than data collection, sample processing, shipment, and analysis of water samples in a laboratory. The acquisition of continuous specific conductance data reduces uncertainty associated with less frequently collected geochemical point data.

The approach synthesizes bioenergetics, reproductive biology, and behavior to estimate the effects of migratory distance and delays incurred at dams on spawning success and survival. Both the magnitude of effects and the consequences of uncertainty in the estimates of input variables are quantified. Behavior, physiology, and energetics strongly affected both the distribution of spawning effort and survival to the marine environment. Delays to both upstream and downstream movements had dramatic effects on spawning success, determining total fecundity and spatial extent of spawning. Delays, combined with cues for migratory reversal, also determined the likelihood of survival. Spawning was concentrated in the immediate vicinity of dams and increased with greater migratory distance and delays to downstream migration. More research is needed on reproductive biology, behavior, energetics, and barrier effects to adequately understand the interplay of the various components of this model; it does provide a framework, however, that suggests that provision of upstream passage at dams in the absence of expeditious downstream passage may increase spawning success - but at the expense of reduced iteroparity.Original Abstract: Nous presentons un modele de simulation dans lequel les adultes migrateurs individuels de l'alose savoureuse (Alosa sapidissima) remontent le fleuve Connecticut et y frayent et les survivants retournent au milieu marin. Notre methodologie integre la bioenergetique, la biologie de la reproduction et le comportement afin d'estimer les effets de la distance de la migration et des delais aux barrages sur le succes de la migration et de la survie. Nous avons mesure a la fois l'importance des effets et les consequences de l'incertitude dans les estimations des variables d'entree. Le comportement, la physiologie et l'energetique affectent fortement tant la repartition de l'effort de fraie que la survie jusqu'au milieu marin. Les delais dans la migration tant ascendante que descendante ont des effets considerables sur le succes de la fraie, sur la determination de la fecondite totale et sur la repartition spatiale de la fraie. Les delais, de meme que les signaux de rebroussement de la migration, determinent aussi la probabilite de la survie. La fraie se concentre dans les environs immediats des barrages et augmente en fonction de la distance de la migration et des delais dans la migration descendante. Il faudrait plus de recherches sur la biologie de la reproduction, le comportement, l'energetique et les effets des barrieres afin de comprendre adequatement les interactions entre les diverses composantes du modele; le modele fournit, neanmoins, un cadre qui indique que l'amenagement de passages vers l'amont dans les barrages en l'absence de passages expeditifs vers l'aval pourrait augmenter le succes de la fraie - mais au prix d'une reduction de l'iteroparite.

Wind tunnel experiments and a variety of ground measurements including air gun, pocket penetrometer, torvane, and roughness chain were conducted in Moab, Utah and cross-validated in the Mojave Desert, California. Patterns between TFV and ground measurements were examined to identify the optimum method for estimating TFV. The results show that TFVs were best predicted using the air gun and penetrometer measurements in the Moab sites. This empirical method, however, systematically underestimated TFVs in the Mojave Desert sites. Further analysis showed that TFVs in the Mojave sites can be satisfactorily estimated with a correction for rock cover, which is presumably the main cause of the underestimation of TFVs. The proposed method may be also applied to estimate TFVs in environments where other non-erodible elements such as postharvest residuals are found.

Passive samplers (semipermeable membrane devices [SPMDs] and polar organic chemical integrative samplers [POCIS]) are well suited for assessing gradients because they can detect synthetic organic compounds (SOCs) at pg L super(-1) concentrations. Semi-permeable membrane devices and POCIS were deployed in Lake Mead, at two sites in Las Vegas Wash, at four sites across Lake Mead, and in the Colorado River downstream from Hoover Dam. Concentrations of hydrophobic SOCs were highest in Las Vegas Wash downstream from waste water and urban inputs and at 8 m depth in Las Vegas Bay (LVB) where Las Vegas Wash enters Lake Mead. The distribution of hydrophobic SOCs showed a lateral distribution across 10 km of Lake Mead from LVB to Boulder Basin. To assess possible vertical gradients of SOCs, SPMDs were deployed at 4-m intervals in 18 m of water in LVB. Fragrances and legacy SOCs were found at the greatest concentrations at the deepest depth. The vertical gradient of SOCs indicated that contaminants were generally confined to within 6 m of the lake bottom during the deployment interval. The high SOC concentrations, warmer water temperatures, and higher total dissolved solids concentrations at depth are indicative of a plume of Las Vegas Wash water moving along the lake bottom. The lateral and vertical distribution of SOCs is discussed in the context of other studies that have shown impaired health of fish exposed to SOCs.

Concerns have emerged about elevated nitrate concentrations in the UFA, which is the source of water supply in this area of northern Florida. At three sites during dry and wet periods in 2007-2008, water samples were collected from the septic tank, shallow and deep lysimeters, and drainfield and background wells in the UFA and analyzed for multiple chemical indicators including nutrients, nitrate isotopes, organic wastewater compounds (OWCs), pharmaceutical compounds, and microbiological indicators (bacteria and viruses). Median NO sub(3)-N concentration in groundwater beneath the septic tank drainfields was 20 mg L super(-1) (8.0-26 mg L super(-1)). After adjusting for dilution, about 25 to 40% N loss (from denitrification, ammonium sorption, and ammonia volatilization) occurs as septic tank effluent moves through the unsaturated zone to the water table. Nitrogen loading rates to groundwater were highly variable at each site (3.9-12 kg N yr super(-1)), as were N and chloride depth profiles in the unsaturated zone. Most OWCs and pharmaceutical compounds were highly attenuated beneath the drainfields; however, five OWCs (caffeine, 1,7-dimethylxanthine, phenol, galaxolide, and tris(dichloroisotopropyl)phosphate) and two pharmaceutical compounds (acetaminophen and sulfamethoxazole) were detected in groundwater samples. Indicator bacteria and human enteric viruses were detected in septic tank effluent samples but only intermittently in soil water and groundwater. Contaminant movement to groundwater beneath each septic tank system also was related to water use and differences in lithology at each site.

Photodecarboxylation was a significant pathway in all cases. Decreases in ketone, aromatic, and O-alkyl carbons were observed throughout the course of the irradiations, whereas C-alkyl carbons resisted photodegradation. Peaks attributable to the low-molecular-weight photodegradation products bicarbonate, formate, acetate, and succinate grew in intensity with irradiation time. The final products of the irradiations were decarboxylated, hydrophobic, predominantly C-alkyl and O-alkyl materials that were resistant to further photodegradation. The total amount of carbon susceptible to loss appeared to be related mainly to the total concentration of carbonyl and aromatic carbons and partly to the concentration of O-alkyl carbons in the fulvic, humic, and XAD-4 acids. The carbon losses for Nordic fulvic, Nordic Humic, Suwannee fulvic, and Suwannee XAD-4 acids were estimated to be 75, 63, 56, and 17%, respectively. More detailed analyses of the effects of irradiation on the carbonyl functionality in Nordic humic acid and Laurentian soil fulvic acid through reaction with hydroxylamine in conjunction with super(15)N nuclear magnetic resonance analysis confirmed preferential photodegradation of the quinone/hydroquinone functionality over ketone groups and the loss of ester groups in Laurentian fulvic acid.

The framework is an integration of two recent approaches: the nonparametric multimodel ensemble forecast technique and the nonparametric space-time disaggregation technique. The four main components of the proposed framework are as follows: (1) an index gauge streamflow is constructed as the sum of flows at all the desired spatial locations; (2) potential predictors of the spring season (April-July) streamflow at this index gauge are identified from the large-scale ocean-atmosphere-land system, including snow water equivalent; (3) the multimodel ensemble forecast approach is used to generate the ensemble flow forecast at the index gauge; and (4) the ensembles are disaggregated using a nonparametric space-time disaggregation technique resulting in forecast ensembles at the desired locations and for all the months within the season. We demonstrate the utility of this technique in skillful forecast of spring seasonal streamflows at four locations in the Upper Colorado River Basin at different lead times. Where applicable, we compare the forecasts to the Colorado Basin River Forecast Center's Ensemble Streamflow Prediction (ESP) and the National Resource Conservation Service "coordinated" forecast, which is a combination of the ESP, Statistical Water Supply, a principal component regression technique, and modeler knowledge. We find that overall, the proposed method is equally skillful to existing operational models while tending to better predict wet years. The forecasts from this approach can be a valuable input for efficient planning and management of water resources in the basin.

We examined health, prevalence and infection intensity of 2 microparasites, coccidia and epitheliocystis-like organisms (ELO), in L. kasmira from their introduced and native range including the islands where translocated fish originated (Tahiti and Marquesas Islands, French Polynesia) and from several other islands (American Samoa, Fiji and New Caledonia). In addition, we did a longitudinal survey of these parasites in the introduced range. Coccidia and ELO were widely distributed and were found on all islands except for New Caledonia. Health indices, as measured by overall organ lesions, body condition and parasite intensity, indicated that fish from Samoa were the least healthy and fish from Midway (Hawaiian Archipelago) were the healthiest. Microparasite diversity was highest on Midway and Hawaii and lowest on New Caledonia. Infection of coccidia followed an asymptotic size-prevalence curve, whereas that of ELO peaked at larger size classes (27.8 cm). Prevalence and aggregation of both parasites in the host varied dynamically over 8 yr with prevalence and aggregation of coccidia being consistently higher and lower, respectively, than ELO. We hypothesize that these parasites are enzootic to the Hawaiian Islands and were not introduced with fish from Tahiti or the Marquesas Islands. Host response and aggregation parameters suggest that coccidia exert a negative effect on their host and probably have an indirect life cycle, whereas ELO appears less pathogenic and has a direct life cycle.

In the sovereign Navajo Nation, an American Indian reservation located in the Four Corners area of the USA, people burn coal in their homes for heat. To explore whether/how indoor coal combustion might contribute to poor respiratory health of residents, this study examined respiratory health data, identified household risk factors such as fuel and stove type and use, analyzed samples of locally used coal, and measured and characterized fine particulate airborne matter inside selected homes. In twenty-five percent of homes surveyed coal was burned in stoves not designed for that fuel, and indoor air quality was frequently found to be of a level to raise concerns. The average winter 24-hour PM 2.5 concentration in 20 homes was 36.0 mu g/ m 3 . This is the first time that PM 2.5 has been quantified and characterized inside Navajo reservation residents' homes.

In addition, mineral deficiencies or excesses may play a role in the development of parasitism/malnutrition syndrome. We measured hepatic mineral values in apparently healthy white-tailed deer from two sites in Virginia, USA, as well as in deer with presumptive parasitism/malnutrition syndrome during 2005- 2007. Deer with presumptive parasitism/malnutrition syndrome that were displaying signs of emaciation and chronic diarrhea had significantly higher mean hepatic levels of magnesium (Mg) and zinc (Zn) compared with healthy deer. Healthy deer in our study from northern Virginia, USA (i.e., Fairfax, Fauquier, Loudoun, and Prince William counties) had significantly lower mean hepatic selenium (Se) levels compared with deer from Nottoway County, Virginia, USA, which is 200 km distant. Healthy deer from northern Virginia, USA, also had significantly lower mean hepatic cobalt (Co), copper (Cu), and molybdenum (Mo) levels. Adult deer had significantly higher mean levels of hepatic iron (Fe) compared with fawns. In addition, male deer had significantly higher mean hepatic Co levels compared with female deer. The significantly higher mean (cSD) level of Zn in sick deer from northern Virginia, USA (78.7c54.9 kg/g versus 35.8c7.4 kg/g in healthy deer) is potentially clinically significant, although no signs consistent with Zn poisoning were observed. All deer in our study from northern Virginia, USA, had marginal or deficient levels of Cu (meancSD=27.4c18.3 kg/g) and Se (mean=0.08c0.03 kg/g), which may be predisposing this population to the development of parasitism/malnutrition syndrome.

Olive ridley turtles (Lepidochelys olivacea) composed the majority of animals examined, and hook-induced perforation of the esophagus was the most common gross lesion followed by perforation of oral structures (tongue, canthus) and of flippers. Gross pathology in the lungs suggestive of drowning was seen in 23 of 71 turtles. Considering only the external gross findings, the pathologist and the observer on board the longline vessel agreed on hook-induced lesions only 60% of the time thereby illustrating the limitations of depending on external examination alone to implicate hooking interactions or drowning as potential cause of sea turtle mortality. When comparing histology of drowned turtles to a control group of nondrowned turtles, the former had significantly more pulmonary edema, hemorrhage, and sloughed columnar epithelium. These microscopic changes may prove useful to diagnose suspected drowning in sea turtles where history of hooking or netting interactions is unknown.

For 150 yr, Laysan Ducks were restricted to an estimated 4 km super(2) of land on Laysan Island in the northwestern Hawaiian Islands. In 2004 and 2005, 42 Laysan Ducks were translocated to Midway Atoll, and the population increased to approximately 200 by 2007. In August 2008, mortality due to botulism type C was identified, and 181 adult, fledgling, and duckling carcasses were collected from August to October. Diseased birds were found on two islands within Midway Atoll at multiple wetlands; however, one wetland contributed most carcasses. The epidemic was discovered approximately 14-21 days after the mortality started and lasted for 50 additional days. The details of this epidemic highlight the disease risk to birds restricted to small island populations and the challenges associated with managing newly translocated endangered species. Frequent population monitoring for early disease detection and comprehensive wetland monitoring and management will be needed to manage avian botulism in endangered Laysan Ducks. Vaccination may also be beneficial to reduce mortality in this small, geographically closed population.

ER - TY - JOUR T1 - Intraspecific Variation in Growth of Marsh Macrophytes in Response to Salinity and Soil Type: Implications for Wetland Restoration AN - 746082680; 12599560 AB - Genetic diversity within plant populations can influence plant community structure along environmental gradients. In wetland habitats, salinity and soil type are factors that can vary along gradients and therefore affect plant growth. To test for intraspecific growth variation in response to these factors, a greenhouse study was conducted using common plants that occur in northern Gulf of Mexico brackish and salt marshes. Individual plants of Distichlis spicata, Phragmites australis, Schoenoplectus californicus, and Schoenoplectus robustus were collected from several locations along the coast in Louisiana, USA. Plant identity, based on collection location, was used as a measure of intraspecific variability. Prepared soil mixtures were organic, silt, or clay, and salinity treatments were 0 or 18psu. Significant intraspecific variation in stem number, total stem height, or biomass was found in all species. Within species, response to soil type varied, but increased salinity significantly decreased growth in all individuals. Findings indicate that inclusion of multiple genets within species is an important consideration for marsh restoration projects that include vegetation plantings. This strategy will facilitate establishment of plant communities that have the flexibility to adapt to changing environmental conditions and, therefore, are capable of persisting over time.

If a positive feedback is confirmed, soil C will represent a source of greenhouse gases that is not currently considered in international protocols to regulate C emissions. We present new estimates of the stocks of soil organic C in Alaska, calculated by linking spatial and field data developed by the USDA NRCS. The spatial data are from the State Soil Geographic database (STATSGO), and the field and laboratory data are from the National Soil Characterization Database, also known as the pedon database. The new estimates range from 32 to 53 Pg of soil organic C for Alaska, formed by linking the spatial and field data using the attributes of Soil Taxonomy. For modelers, we recommend an estimation method based on taxonomic subgroups with interpolation for missing areas, which yields an estimate of 48 Pg. This is a substantial increase over a magnitude of 13 Pg estimated from only the STATSGO data as originally distributed in 1994, but the increase reflects different estimation methods and is not a measure of the change in C on the landscape. Pedon samples were collected between 1952 and 2002, so the results do not represent a single point in time. The linked databases provide an improved basis for modeling the impacts of climate change on net ecosystem exchange.

Annual flow-weighted concentration plots display the same long-term patterns of decline, but are less noisy because they reduce/eliminate variations due to interannual discharge differences. The declines appear greatest in the middle MRB, but also are evident elsewhere. The pattern for the lower Ohio River differs and may reflect ongoing construction at the Olmsted lock and dam that began in 1993 and currently is ongoing. The Great Flood of 1993 appears to have superimposed a step function (a sharp drop) on the long-term rate of decline in suspended sediment concentrations (SSC), annual fluxes and flow-weighted concentrations in the middle MRB at St Louis and Thebes, Missouri and Vicksburg, Mississippi, and in the lower MRB at St Francisville, Louisiana. Evidence for a step function at other sites is less substantial, but may have occurred. The step function appears to have resulted from losses in available (erodible) sediment, rather than to a reduction in discharge; hence, the MRB appears to be supply limited rather than discharge limited. These evaluations support the need for daily discharge and SSC data collections in the MRB to better address questions regarding long-term trends in sediment-related issues.

High islands are subjected to constant erosion over geologic time, which establishes an important source of terrigeneous sediment for nearby marine communities. Many of these sediments are deposited in mangrove forests and offer mangroves a potentially important means for adjusting surface elevation with rising sea level. In this study, we investigated sedimentation and elevation dynamics of mangrove forests in three hydrogeomorphic settings on the islands of Kosrae and Pohnpei, Federated States of Micronesia (FSM). Surface accretion rates ranged from 2.9 to 20.8mmy super(-1), and are high for naturally occurring mangroves. Although mangrove forests in Micronesian high islands appear to have a strong capacity to offset elevation losses by way of sedimentation, elevation change over 6[frac12] years ranged from -3.2 to 4.1mmy super(-1), depending on the location. Mangrove surface elevation change also varied by hydrogeomorphic setting and river, and suggested differential, and not uniformly bleak, susceptibilities among Pacific high island mangroves to sea-level rise. Fringe, riverine, and interior settings registered elevation changes of -1.30, 0.46, and 1.56mmy super(-1), respectively, with the greatest elevation deficit (-3.2mmy super(-1) ) from a fringe zone on Pohnpei and the highest rate of elevation gain (4.1mmy super(-1)) from an interior zone on Kosrae. Relative to sea-level rise estimates for FSM (0.8-1.8mmy super(-1)) and assuming a consistent linear trend in these estimates, soil elevations in mangroves on Kosrae and Pohnpei are experiencing between an annual deficit of 4.95mm and an annual surplus of 3.28mm. Although natural disturbances are important in mediating elevation gain in some situations, constant allochthonous sediment deposition probably matters most on these Pacific high islands, and is especially helpful in certain hydrogeomorphic zones. Fringe mangrove forests are most susceptible to sea-level rise, such that protection of these outer zones from anthropogenic disturbances (for example, harvesting) may slow the rate at which these zones convert to open water.

The first half of a tracer survey performed approximately 40 days after the injection found a small percentage of the tracer on the ridge axis between 9 degree 30"N and 10 degree 10"N, with the main concentration near 9 degree 50"N, a site of many active hydrothermal vents. These observations provide evidence of larval connectivity between vent sites on the ridge. The latter half of the survey detected the primary patch of tracer west of the ridge and just south of the Lamont Seamounts, as a majority of the tracer had been transported off the ridge. However, by the end of the survey, the eastern edge of this patch was transported back to within 10km of the ridge crest at 9 degree 50"N by a reversal in the subinertial flow, suggesting another pathway for larvae between points along the ridge. Both the horizontal and vertical distributions of the tracer were complex and were likely heavily influenced by topography and vents in the area. Elevated tracer concentrations within the axial summit trough and an adjacent depression on the upper ridge flank suggest that tracers may be detained in such depressions. Correlated tracer/turbidity profiles provide direct evidence of entrainment of the tracer into vent plumes from 9 degree 30"N to 10 degree N. A comparison of the vertical tracer inventory with neutral density vent-plume observations suggests that on the order of 10% of the tracer injected was entrained into vent plumes near the injection site. The results imply that effluent from diffuse hydrothermal sources and larvae of hydrothermal vent fauna can be entrained in significant quantities into plumes from discrete sources and dispersed in the neutrally buoyant plumes.

We sampled MeHg and total mercury (THg) concentrations in two aquatic macroinvertebrate taxa at the inlets, centers, and outlets of four replicated wetland habitats (8 wetlands total) during two time periods bounding the rice growing season and corresponding to flood-up and pre-harvest (96 total samples). In general, THg concentrations (meanAcstandard error) in Notonectidae (Notonecta, back swimmers; 1.18 plus or minus 0.08 mu g g super(-1) dry weight [dw]) were higher than in Corixidae (Corisella, water boatmen; 0.89 plus or minus 0.06 mu g g super(-1) dw, MeHg: 0.74 plus or minus 0.05 mu g g super(-1) dw). MeHg concentrations were correlated with THg concentrations in Corixidae (R2=0.80) and 88% of THg was in the MeHg form. Wetland habitat type had an important influence on THg concentrations in aquatic invertebrates, but this effect depended on the sampling time period and taxa. In particular, THg concentrations in Notonectidae, but not Corixidae, were higher in permanent wetlands than in white rice, wild rice, or shallowly-flooded fallow fields. THg concentrations in Notonectidae were higher at the end of the rice growing season than near the time of flood-up, whereas THg concentrations in Corixidae did not differ between time periods. The effect of wetland habitat type was more prevalent near the end of the rice growing season, when Notonectidae THg concentrations were highest in permanent wetlands. Additionally, invertebrate THg concentrations were higher at water outlets than at inlets of wetlands. Our results indicate that although invertebrate THg concentrations increased from the time of flood-up to draw-down of wetlands, temporarily flooded habitats such as white rice, wild rice, and shallowly-flooded fallow fields did not have higher THg or MeHg concentrations in invertebrates than permanent wetlands.

D.A. Webb] orchard and cornfield (Zea mays L.) in the lower Merced River study basin, California; and corn-soybean [Glycine max (L.) Merr.] rotations in study basins at Maple Creek, Nebraska, and at Morgan Creek, Maryland. We used inverse modeling with a new version of the Root Zone Water Quality Model (RZWQM2) to estimate soil hydraulic and nitrogen transformation parameters throughout the unsaturated zone; previous versions were limited to 3-m depth and relied on manual calibration. The overall goal of the modeling was to derive unsaturated zone N mass balances for the four sites. RZWQM2 showed promise for deeper simulation profiles. Relative root mean square error (RRMSE) values for predicted and observed nitrate concentrations in lysimeters were 0.40 and 0.52 for California (6.5 m depth) and Nebraska (10 m), respectively, and index of agreement (d) values were 0.60 and 0.71 (d varies between 0 and 1, with higher values indicating better agreement). For the shallow simulation profile (1 m) in Maryland, RRMSE and d for nitrate were 0.22 and 0.86, respectively. Except for Nebraska, predictions of average nitrate concentration at the bottom of the simulation profile agreed reasonably well with measured concentrations in monitoring wells. The largest additions of N were predicted to come from inorganic fertilizer (153-195 kg N ha super(-1) yr super(-1) in California) and N fixation (99 and 131 kg N ha super(-1) yr super(-1) in Maryland and Nebraska, respectively). Predicted N losses occurred primarily through plant uptake (144-237 kg N ha super(-1) yr super(-1)) and deep seepage out of the profile (56-102 kg N ha super(-1) yr super(-1)). Large reservoirs of organic N (up to 17,500 kg N ha super(-1) m super(-1) at Nebraska) were predicted to reside in the unsaturated zone, which has implications for potential future transfer of nitrate to groundwater.

Here we measured the propensity of leachates from four crops and four aquatic macrophytes to form trihalomethanes (THMs)-a regulated class of DBPs-before and after 21 d of microbial degradation. We also measured lignin phenol content and specific UV absorbance (SUVA sub(254)) to test the assumption that aromatic compounds from vascular plants are resistant to microbial degradation and readily form DBPs. Leaching solubilized 9 to 26% of total plant carbon, which formed 1.93 to 6.72 mmol THM mol C super(-1). However, leachate DOC concentrations decreased by 85 to 92% over the 21-d incubation, with a concomitant decrease of 67 to 92% in total THM formation potential. Carbon-normalized THM yields in the residual DOC pool increased by 2.5 times on average, consistent with the preferential uptake of nonprecursor material. Lignin phenol concentrations decreased by 64 to 96% over 21 d, but a lack of correlation between lignin content and THM yields or SUVA sub(254) suggested that lignin-derived compounds are not the source of increased THM precursor yields in the residual DOC pool. Our results indicate that microbial carbon utilization alters THM precursors in ecosystems with direct plant leaching, but more work is needed to identify the specific dissolved organic matter components with a greater propensity to form DBPs and affect watershed management, drinking water quality, and human health.

Most precipitation events in these ecosystems are small (<=10 mm), but can stimulate carbon flux. The large proportion of carbon stored belowground and small carbon inputs create the potential for these small precipitation events to have large effects on carbon cycling. Land-use change can modify these effects through alteration of the biota and soil resources. The goal of our research was to determine how small precipitation events (2, 5, and 10 mm) affected the dynamics of soil carbon flux and water loss in previously cultivated Conservation Reserve Program (CRP) fields and undisturbed shortgrass steppe. Total carbon loss and duration of elevated carbon flux increased as event size increased in all field types. Time since cultivation increased in importance for carbon flux as event size increased. A comparison of water loss rates to carbon flux suggests that water is limiting to carbon flux for the smallest events, but is less limiting for events above 5 mm. We also describe how water availability interacts with temperature in controlling carbon flux rate. We conclude that small precipitation events have the potential for large short-term losses of carbon in the shortgrass steppe.

Satellite instruments view volcanic thermal features across the globe at various temporal and spatial resolutions. Thermal features that may be a precursor to a major eruption, or indicative of important changes in an on-going eruption can be subtle, making them challenging to reliably identify with satellite instruments. The goal of this study was to explore the limits of the types and magnitudes of thermal anomalies that could be detected using satellite thermal infrared (TIR) data. Specifically, the characterization of sub-pixel thermal features with a wide range of temperatures is considered using ASTER multispectral TIR data. First, theoretical calculations were made to define a "thermal mixing detection threshold" for ASTER, which quantifies the limits of ASTER's ability to resolve sub-pixel thermal mixing over a range of hot target temperatures and % pixel areas. Then, ASTER TIR data were used to model sub-pixel thermal features at the Yellowstone National Park geothermal area (hot spring pools with temperatures from 40 to 90 degrees C) and at Mount Erebus Volcano, Antarctica (an active lava lake with temperatures from 200 to 800 degrees C). Finally, various sources of uncertainty in sub-pixel thermal calculations were quantified for these empirical measurements, including pixel resampling, atmospheric correction, and background temperature and emissivity assumptions.

AN - 734162762; 19906406 AB - Mixtures of organochlorine compounds have the potential for additive or interactive toxicity to organisms exposed in the stream. This study uses a variety of methods to identify mixtures and a modified concentration-addition approach to estimate their potential toxicity at 845 stream sites across the United States sampled between 1992 and 2001 for organochlorine pesticides and polychlorinated biphenyls (PCBs) in bed sediment. Principal-component (PC) analysis identified five PCs that account for 77% of the total variance in 14 organochlorine compounds in the original dataset. The five PCs represent: (1) chlordane-related compounds and dieldrin; (2) p,p'-DDT and its degradates; (3) o,p'-DDT and its degradates; (4) the pesticide degradates oxychlordane and heptachlor epoxide; and (5) PCBs. The PC analysis grouped compounds that have similar chemical structure (such as parent compound and degradate), common origin (in the same technical pesticide mixture), and(or) similar relation of concentrations to land use. For example, the highest concentrations of chlordane compounds and dieldrin occurred at urban sites, reflecting past use of parent pesticides for termite control. Two approaches to characterizing mixtures--PC-based mixtures and unique mixtures--were applied to all 299 samples with a detection of two or more organochlorine compounds. PC-based mixtures are defined by the presence (in the sample) of one or more compounds associated with that PC. Unique mixtures are defined as a specific combination of two or more compounds detected in a sample, regardless of how many other compounds were also detected in that sample. The simplest PC-based mixtures (containing compounds from 1 or 2 PCs) commonly occurred in a variety of land use settings. Complex mixtures (containing compounds from 3 or more PCs) were most common in samples from urban and mixed/urban sites, especially in the Northeast, reflecting high concentrations of multiple chlordane, dieldrin, DDT-related compounds, and(or) PCBs. The most commonly occurring unique mixture (p,p'-DDE, p,p'-DDD) occurred in both simple and complex PC-based mixtures, and at both urban and agricultural sites. Mean Probable Effect Concentration Quotients (PEC-Q) values, which estimate the potential toxicity of organochlorine contaminant mixtures, were highest for complex mixtures. Mean PEC-Q values were highest for urban sites in the Northeast, followed by mixed/urban sites in the Northeast and agricultural sites in cotton growing areas. These results demonstrate that the PEC-Q approach can be used in combination with PC-based and unique mixture analyses to relate potential aquatic toxicity of contaminant mixtures to mixture complexity, land use, and other surrogates for contaminant sources.

AN - 21425171; 12491097 AB - Wolves (Canis lupus) in North America are considered obligate predators of ungulates with other food resources playing little role in wolf population dynamics or wolf-prey relations. However, spawning Pacific salmon (Oncorhyncus spp.) are common throughout wolf range in northwestern North America and may provide a marine subsidy affecting inland wolf-ungulate food webs far from the coast. We conducted stable-isotope analyses for nitrogen and carbon to evaluate the contribution of salmon to diets of wolves in Denali National Park and Preserve, 1200 river-km from tidewater in interior Alaska, USA. We analyzed bone collagen from 73 wolves equipped with radio collars during 1986-2002 and evaluated estimates of salmon in their diets relative to the availability of salmon and ungulates within their home ranges. We compared wolf densities and ungulate: wolf ratios among regions with differing salmon and ungulate availability to assess subsidizing effects of salmon on these wolf-ungulate systems. Wolves in the northwestern flats of the study area had access to spawning salmon but low ungulate availability and consumed more salmon (17% c 7% [mean c SD]) than in upland regions, where ungulates were sixfold more abundant and wolves did or did not have salmon spawning areas within their home ranges (8% c 6% and 3% c 3%, respectively). Wolves were only 17% less abundant on the northwestern flats compared to the remainder of the study area, even though ungulate densities were 78% lower. We estimated that biomass from fall runs of chum (O. keta) and coho (O. kisutch) salmon on the northwestern flats was comparable to the ungulate biomass there, and the contribution of salmon to wolf diets was similar to estimates reported for coastal wolves in southeast Alaska. Given the ubiquitous consumption of salmon by wolves on the northwestern flats and the abundance of salmon there, we conclude that wolf numbers in this region were enhanced by the allochthonous subsidy provided by salmon and discuss implications for wolf-ungulate relations.

We present data suggesting that free-ranging elk (Cervus elaphus) are a maintenance host for Brucella abortus in new areas of the Greater Yellowstone Ecosystem (GYE). Brucellosis seroprevalence in free-ranging elk increased from 0-7% in 1991-1992 to 8-20% in 2006-2007 in four of six herd units around the GYE. These levels of brucellosis are comparable to some herd units where elk are artificially aggregated on supplemental feeding grounds. There are several possible mechanisms for this increase that we evaluated using statistical and population modeling approaches. Simulations of an age-structured population model suggest that the observed levels of seroprevalence are unlikely to be sustained by dispersal from supplemental feeding areas with relatively high seroprevalence or an older age structure. Increases in brucellosis seroprevalence and the total elk population size in areas with feeding grounds have not been statistically detectable. Meanwhile, the rate of seroprevalence increase outside the feeding grounds was related to the population size and density of each herd unit. Therefore, the data suggest that enhanced elk-to-elk transmission in free-ranging populations may be occurring due to larger winter elk aggregations. Elk populations inside and outside of the GYE that traditionally did not maintain brucellosis may now be at risk due to recent population increases. In particular, some neighboring populations of Montana elk were 5-9 times larger in 2007 than in the 1970s, with some aggregations comparable to the Wyoming feeding-ground populations. Addressing the unintended consequences of these increasing populations is complicated by limited hunter access to private lands, which places many ungulate populations out of administrative control. Agency-landowner hunting access partnerships and the protection of large predators are two management strategies that may be used to target high ungulate densities in private refuges and reduce the current and future burden of disease.

However, due to factors such as phenotypic plasticity, ecotypic variation, and evolved tolerance to thermal stress, it remains poorly understood whether losses should be greatest in populations experiencing the greatest climatic change or living in places where the prevailing climate is closest to the edge of the species' bioclimatic envelope (e.g., at the hottest, driest sites). Research on American pikas (Ochotona princeps) in montane areas of the Great Basin during 1994-1999 suggested that 20th-century population extirpations were predicted by a combination of biogeographic, anthropogenic, and especially climatic factors. Surveys during 2005-2007 documented additional extirpations and within-site shifts of pika distributions at remaining sites. To evaluate the evidence in support of alternative hypotheses involving effects of thermal stress on pikas, we placed temperature sensors at 156 locations within pika habitats in the vicinity of 25 sites with historical records of pikas in the Basin. We related these time series of sensor data to data on ambient temperature from weather stations within the Historical Climate Network. We then used these highly correlated relationships, combined with long-term data from the same weather stations, to hindcast temperatures within pika habitats from 1945 through 2006. To explain patterns of loss, we posited three alternative classes of direct thermal stress: (1) acute cold stress (number of days below a threshold temperature); (2) acute heat stress (number of days above a threshold temperature); and (3) chronic heat stress (average summer temperature). Climate change was defined as change in our thermal metrics between two 31-yr periods: 1945-1975 and 1976-2006. We found that patterns of persistence were well predicted by metrics of climate. Our best models suggest some effects of climate change; however, recent and long-term metrics of chronic heat stress and acute cold stress, neither previously recognized as sources of stress for pikas, were some of the best predictors of pika persistence. Results illustrate that extremely rapid distributional shifts can be explained by climatic influences and have implications for conservation topics such as reintroductions and early-warning indicators.

Study of its occurrence patterns is hampered by false negatives: the failure to detect the pathogen when it is present. Occupancy models are a useful but currently underutilized tool for analyzing detection data when the probability of detecting a species is <1. We use occupancy models to evaluate hypotheses concerning the occurrence and prevalence of B. dendrobatidis and discuss how this application differs from a conventional occupancy approach. We found that the probability of detecting the pathogen, conditional on presence of the pathogen in the anuran population, was related to amphibian development stage, day of the year, elevation, and human activities. Batrachochytrium dendrobatidis was found throughout our study area but was only estimated to occur in 53.4% of 78 populations of native amphibians and 66.4% of 40 populations of nonnative Rana catesbeiana tested. We found little evidence to support any spatial hypotheses concerning the probability that the pathogen occurs in a population, but did find evidence of some taxonomic variation. We discuss the interpretation of occupancy model parameters, when, unlike a conventional occupancy application, the number of potential samples or observations is finite.

Merr.] agriculture were studied to determine the effects of different hydrogeologic settings of the Northern Atlantic Coastal Plain (NACP) on the transport of nutrients and pesticides in groundwater. Settings ranged from predominantly well-drained soils overlying thick, sandy surficial aquifers to predominantly poorly drained soils with complex aquifer stratigraphy and high organic matter content. Apparent age of groundwater, dissolved gases, N isotopes, major ions, selected pesticides and degradates, and geochemical environments in groundwater were studied. Agricultural chemicals were the source of most dissolved ions in groundwater. Specific conductance was strongly correlated with reconstructed nitrate (the sum of N in nitrate and N gas) (R super(2) = 0.81, p < 0.0001), and is indicative of the relative degree of agricultural effects on groundwater. Trends in nitrate were primarily related to changes in manure and fertilizer use at the well-drained sites where aquifer conditions were consistently oxic. Nitrate was present in young groundwater but completely removed over time through denitrification at the poorly drained sites where there were variations in chemical input and in geochemical environment. Median concentrations of atrazine (6-chloro-N-ethyl-N'-(1-methylethyl)-1,3,5-triazine-2,4-diamine), metolachlor (2-chloro-N-(2-ethyl- 6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide), and some of their common degradates were higher at well-drained sites than at poorly drained sites, with concentrations of degradates generally higher than those of the parent compounds at all sites. An increase in the percentage of deethylatrazine to total atrazine over time at one well-drained site may be related to changes in manure application.

This greater-than-fivefold increase in density coincided with the dreissenid mussel invasion of Lake Michigan. Intervention analysis revealed that ninespine stickleback density in Lake Michigan significantly increased between the two time periods. In contrast, based on data from our annual bottom trawl survey of U.S. waters of Lake Superior, ninespine stickleback density decreased from an average of 0.133 kg/ha during 1978-1999 to an average of only 0.026 kg/ha during 2000-2007. This greater-than-fivefold density decrease, which was found to be significant via intervention analysis, coincided with population recovery for both lean and fat morphotypes of lake trout Salvelinus namaycush in Lake Superior. In contrast to Lake Michigan, dreissenid mussels have not invaded Lake Superior on a lakewide basis. Thus, a comparison of these two lakes indicated that the increase in ninespine stickleback abundance in Lake Michigan was most likely attributable to the dreissenid mussel invasion. In addition, based on our correlation analysis, alewives Alosa pseudoharengus did not have an adverse effect on ninespine stickleback abundance in Lake Michigan. Perhaps the recent increase in biomass of green algae Cladophora spp. associated with the dreissenid mussel invasion improved spawning habitat quality for ninespine sticklebacks and led to their stepwise abundance increase in Lake Michigan beginning in 1996.

Experimental series were initiated during early, middle, and late periods of the spring smolt migration (April 25, May 11, and May 31, respectively). For each time series, descaled smolts (subjected to descaling on 10% of the body surface area) and control smolts (held out of water for 15 s) were transferred to seawater at 0, 1, 3, or 7 d posttreatment. After fish were held in 35ppt seawater for 24 h, gill and blood samples were collected and analyzed for Na super(+),K super(+)-ATPase activity and plasma osmolyte levels. Based on gill Na super(+),K super(+)-ATPase activity, the three series spanned the period from early smolting (increasing activity) to de-smolting (decreasing activity). In each series, descaled fish transferred to seawater at 0 and 1 d posttreatment had greater plasma osmolality than control fish; descaled fish transferred to seawater at 3 d posttreatment did not differ from controls. The greatest perturbation in osmolality (70 milliosmoles) was observed at the peak of smolting (middle series), whereas lesser increases were seen for early and late-series smolts. The observed osmotic perturbations in descaled fish would probably reduce performance and decrease survival during smolt migration.

Before treatment, combined Ra ( super(226)Ra plus super(228)Ra) concentrations (maximum, 1.54 Bq L super(-1)) exceeded the 0.185 Bq L super(-1) Maximum Contaminant Level in 4 of 10 studied domestic-well waters (median pH, 4.90). At the water table downgradient from leachfields, combined Ra concentrations were low (commonly 5.3, indicating sequestration; when pH was <=5.3 (acidic), concentrations were elevated (maximum, 0.985 Bq L super(-1) - greater than concentrations in corresponding discharged septic-tank effluents (maximum, 0.243 Bq L super(-1))), indicating Ra mobilization from leachfield sediments. Confidence in quantification of Ra mass balance was reduced by study design limitations, including synoptic sampling of effluents and ground waters, and large uncertainties associated with analytical methods.

This interpretive structure will illustrate how defense priorities shifted as the war evolved, how the Army assigned higher priorities to the U.S. Army Corps of Engineers' hydropower dams than Reclamation's, and how the Army sent its worst soldiers to the desert to protect Hoover Dam. Also mentioned is the sole material remnant of this protection effort, a fortified machine gun bunker that sits above the dam. It not only serves as a symbol of the war effort, it is soon slated to become a historic interpretive site.

Most of the concrete for the dam was mass concrete made with up to 9-inch maximum size aggregate (MSA). The original 28-day compressive strength tests performed for quality assurance during construction were found to be in the 3,500 lb/in super(2) range. In 1995, the Bureau of Reclamation's Materials Engineering and Research Laboratory completed a testing program to evaluate the long term properties of the Hoover Dam concrete. Compressive strengths at this time were found to average 7,230 lb/in super(2). Discussions will include the core sample locations and compressive, tensile and shear strength test results from this study, along with a discussion of determining the need for the core testing program.

AN - 1777134758; 11821840 AB - The physical science linking human-induced increases in greenhouse gasses to the warming of the global climate system is well established, but the implications of this warming for ecosystem processes and services at regional scales is still poorly understood. Thus, the objectives of this work were to: (1) describe rates of change in temperature averages and extremes for western Montana, a region containing sensitive resources and ecosystems, (2) investigate associations between Montana temperature change to hemispheric and global temperature change, (3) provide climate analysis tools for land and resource managers responsible for researching and maintaining renewable resources, habitat, and threatened/endangered species and (4) integrate our findings into a more general assessment of climate impacts on ecosystem processes and services over the past century. Over 100years of daily and monthly temperature data collected in western Montana, USA are analyzed for long-term changes in seasonal averages and daily extremes. In particular, variability and trends in temperature above or below ecologically and socially meaningful thresholds within this region (e.g., -17.8C (0F), 0C (32F), and 32.2C (90F)) are assessed. The daily temperature time series reveal extremely cold days (,-17.8C) terminate on average 20days earlier and decline in number, whereas extremely hot days (.32C) show a three-fold increase in number and a 24-day increase in seasonal window during which they occur. Results show that regionally important thresholds have been exceeded, the most recent of which include the timing and number of the 0C freeze/thaw temperatures during spring and fall. Finally, we close with a discussion on the implications for Montana's ecosystems. Special attention is given to critical processes that respond non-linearly as temperatures exceed critical thresholds, and have positive feedbacks that amplify the changes.

Concentrations of 28 organochlorine pesticides, 160 polychlorinated biphenyl (PCB) congeners, and 17 dioxin and furan (PCDD-F) congeners were quantified in kingfisher eggs. The pattern of organochlorine pesticides and PCDD-F congeners did not differ significantly between 14 eggs collected from individual nests on the Hudson River and five eggs similarly collected on three other nearby rivers. In contrast, the pattern of PCB congeners in eggs collected on the Hudson River differed significantly from the other rivers. The differences in patterns of PCB congeners were associated with a higher representation of lower-numbered congeners on the Hudson River than the other rivers. The higher prevalence of the lower-numbered congeners and lower prevalence of the higher-numbered congeners is consistent with Aroclor 1016 and 1242 being the source of the PCBs on the Hudson River. Concentrations in a sample egg collected at each nest were compared to nest survival and egg success (the proportion of eggs hatching in a clutch if at least one egg hatched) of the remaining eggs in the clutch. Models that predicted nest survival and egg success as functions of contaminant levels were poorly distinguished from models that presumed no such associations. Small sample sizes could have contributed to the inability to distinguish among contaminant and no toxicant models. However, we cannot rule out the possibility that contaminant concentrations on the Hudson River were not sufficiently high to demonstrate a relationship between contaminant concentrations and reproductive success in kingfishers.

This paper will summarize the hydraulic investigations and their impact on the Hoover Dam design as well as some of the field challenges associated with the construction and operation of Hoover Dam. The salient results of the initial spillway and outlet works model studies conducted at various venues, model scales, and with several design options will be reviewed. More recent hydraulic studies will be presented of the penstock tie rods, intake tower cylinder gate performance, replacement of the internal differential needle valves, and repair and solution for cavitation damage in the elbow of the spillway tunnels. The initial and subsequent studies related to hydraulic design and performance at Hoover Dam have produced standards and criteria that have greatly added to the world-wide knowledge base for today's hydraulic structure design. The design, experimental investigations and construction of the Hoover Dam pushed the science of hydraulics to new frontiers.

The purpose of the work is to infer source rocks from oil geochemistry and to improve understanding of the effects of variable organofacies and commingling on crude oil composition. Hierarchical cluster analysis and principal components analysis readily identify the well-known Eocene Kreyenhagen and Miocene Monterey formations as the two principal source rocks in the basin. However, enhanced resolution provided by multiple tiers of K-Nearest Neighbor models in a chemometric decision tree identifies multiple source-rock organofacies for both source rocks. The results show a remarkably strong correlation of the identified oil families with geographic distribution and reservoir rock interval. For example, the data differentiate at least two families of oil samples that originated from different distal marine shale organofacies of the Kreyenhagen Formation. One family is depleted in (super 13) C and shows higher C (sub 28) /C (sub 29) steranes than the other. This family occurs almost exclusively in Eocene reservoir rocks within the Coalinga, Guijarral Hills, Kettleman North Dome, and San Joaquin fields. The Miocene Monterey oil samples fall into at least seven genetically distinct families. For example, one family has negative stable carbon isotope ratios and elevated C (sub 29) steranes compared to the other Miocene oil samples. This family occurs almost exclusively in Pliocene or Upper Miocene reservoir rocks in the Elk Hills field. Another family occurs in the southernmost part of the San Joaquin basin and is characterized by low diasteranes and high 28,30-bisnorhopane. This family occurs in Middle and Upper Miocene reservoir rocks mainly in the Pleito Ranch field.

Science- based guidance was sought in defining how groundwater or surface-water withdrawals affect streamflow and in quantifying the relation between reduced streamflow and changes in stream ecology. The implementation of the legislation led to a risk-based system based on a gradient of risk, ecological response curves, and estimation of groundwater-surface water interaction. All Michigan streams are included in the legislation, and, accordingly, all Michigan streams were classified into management types defined by size of watershed, stream-water temperature, and predicted fish assemblages. Different streamflow removal percentages define risk-based thresholds allowed for each type. These removal percentages were informed by ecological response curves of characteristic fish populations and finalized through a legislative workgroup process. The assessment process includes an on-line screening tool that may be used to evaluate new or increased withdrawals against the risk-based zones and allows withdrawals that are not likely to cause an ARI to proceed to water-use registration. The system is designed to consider cumulative impacts of high-capacity withdrawals and to promote user involvement in water resource management by the establishment of water-user committees as cumulative withdrawals indicate greater potential for ARI in the watershed.

Tracer experiments were conducted prior to and following reconfiguration and replanting of a 1.2 ha treatment wetland from its original design of alternating shallow and deep zones to incorporate hummocks (shallow planting beds situated perpendicular to flow). Tracer test data were analyzed using analysis of moments and the one-dimensional transport with inflow and storage numerical model to evaluate the effects of the seasonal vegetation growth cycle and hummocks on solute transport. Following reconfiguration, vegetation coverage was relatively small, and minor changes in spatial distribution influenced wetland hydraulics. During start-up conditions, the wetland underwent an acclimation period characterized by small vegetation coverage and large transport cross-sectional areas. At the start of the growing season, new growth of emergent vegetation enhanced hydraulic performance. At the end of the growing season, senescing vegetation created short-circuiting. Wetland hydrodynamics were associated with high volumetric efficiencies and velocity heterogeneities. The hummock design resulted in breakthrough curves characterized by multiple secondary tracer peaks indicative of varied flow paths created by bottom topography.
