TY - JOUR T1 - Water balance dynamics in the Nile Basin AN - 746013635; 13161285 AB - Understanding the temporal and spatial dynamics of key water balance components of the Nile River will provide important information for the management of its water resources. This study used satellite-derived rainfall and other key weather variables derived from the Global Data Assimilation System to estimate and map the distribution of rainfall, actual evapotranspiration (ETa), and runoff. Daily water balance components were modelled in a grid-cell environment at 0.1 degree (10 km) spatial resolution for 7 years from 2001 through 2007. Annual maps of the key water balance components and derived variables such as runoff and ETa as a percent of rainfall were produced. Generally, the spatial patterns of rainfall and ETa indicate high values in the upstream watersheds (Uganda, southern Sudan, and southwestern Ethiopia) and low values in the downstream watersheds. However, runoff as a percent of rainfall is much higher in the Ethiopian highlands around the Blue Nile subwatershed. The analysis also showed the possible impact of land degradation in the Ethiopian highlands in reducing ETa magnitudes despite the availability of sufficient rainfall. Although the model estimates require field validation for the different subwatersheds, the runoff volume estimate for the Blue Nile subwatershed is within 7.0% of a figure reported from an earlier study. Further research is required for a thorough validation of the results and their integration with ecohydrologic models for better management of water and land resources in the various Nile Basin ecosystems.

To understand the soil physics controlling runoff for these initial conditions, we used a small, portable disk infiltrometer to measure two hydraulic properties: (1) near-saturated hydraulic conductivity, K sub(f) and (2) sorptivity, S(q sub(i)), as a function of initial soil moisture content, q sub(i), ranging from extremely dry conditions (q sub(i)<0.02cm super(3)cm super(-) super(3)) to near saturation. In the field and in the laboratory replicate measurements were made of ash, reference soils, soils unaffected by fire, and fire-affected soils. Each has a different degrees of water repellency that influences K sub(f) and S(q sub(i)). Values of K sub(f) ranged from 4.5x10 super(-) super(3) to 53x10 super(-) super(3)cms super(-) super(1) for ash; from 0.93x10 super(-) super(3) to 130x10 super(-) super(3)cms super(-) super(1) for reference soils; and from 0.86x10 super(-) super(3) to 3.0x10 super(-) super(3)cms super(-) super(1), for soil unaffected by fire, which had the lowest values of K sub(f). Measurements indicated that S(q sub(i)) could be represented by an empirical non-linear function of q sub(i) with a sorptivity maximum of 0.18-0.20cms super(-) super(0) super(.) super(5), between 0.03 and 0.08cm super(3)cm super(-) super(3). This functional form differs from the monotonically decreasing non-linear functions often used to represent S(q sub(i)) for rainfall-runoff modeling. The sorptivity maximum may represent the combined effects of gravity, capillarity, and adsorption in a transitional domain corresponding to extremely dry soil, and moreover, it may explain the observed non-linear behavior, and the critical soil-moisture threshold of water repellent soils. Laboratory measurements of K sub(f) and S(q sub(i)) are the first for ash and fire-affected soil, but additional measurements are needed of these hydraulic properties for in situ fire-affected soils. They provide insight into water repellency behavior and infiltration under extremely dry conditions. Most importantly, they indicate how existing rainfall-runoff models can be modified to accommodate a possible two-layer system in extremely dry conditions. These modified models can be used to predict floods from burned watersheds under these initial conditions.

The spatial model was developed using water depth, riverbed slope and roughness, fish positions collected in 2002, and Mahalanobis distance (D super(2)). We created a habitat suitability map by identifying a Mahalanobis distance under which >50% of white sturgeon locations occurred in 2002 (i.e., high-probability habitat). White sturgeon preferred relatively moderate to high water depths, and low to moderate riverbed slope and roughness values. The eigenvectors indicated that riverbed slope and roughness were slightly more important than water depth, but all three variables were important. We estimated the impacts that fill might have on sturgeon habitat by simulating the addition of fill to the thalweg, in 3-m increments, and recomputing Mahalanobis distances. Channel filling simulations revealed that up to 9m of fill would have little impact on high-probability habitat, but 12 and 15m of fill resulted in habitat declines of ~12% and ~45%, respectively. This is the first spatially explicit predictive model of white sturgeon rearing habitat in the lower Columbia River, and the first to quantitatively predict the impacts of dredging operations on sturgeon habitat. Future research should consider whether water velocity improves the accuracy and specificity of the model, and to assess its applicability to other areas in the Columbia River.

Nineteen pesticides were detected: eight herbicides, nine insecticides, one fungicide and one insecticide synergist. Concentrations for the herbicides (0.1 to 3000ng/g; median of 6.1ng/g) were generally greater than those for the insecticides (0.2 to 51ng/g; median of 1.5ng/g). Concentrations in the tributaries were usually greater than in the mainstem San Joaquin River and the west side tributaries were higher than the east side tributaries. Estimated instantaneous loads ranged from 1.3 to 320g/day for herbicides and 0.03 to 53g/day for insecticides. The greatest instantaneous loads came from the Merced River on the east side. Instantaneous loads were greater for the first storm of 2008 than the second storm in the tributaries while the instantaneous loads within the San Joaquin River were greater during the second storm. Pesticide detections generally reflected pesticide application, but other factors such as physical-chemical properties and timing of application were also important to pesticide loads.

Bats of certain species are dying at wind turbines in unprecedented numbers. Species of bats consistently affected by turbines tend to be those that rely on trees as roosts and most migrate long distances. Although considerable progress has been made in recent years toward better understanding the problem, the causes of bat fatalities at turbines remain unclear. In this synthesis, we review hypothesized causes of bat fatalities at turbines. Hypotheses of cause fall into 2 general categories--proximate and ultimate. Proximate causes explain the direct means by which bats die at turbines and include collision with towers and rotating blades, and barotrauma. Ultimate causes explain why bats come close to turbines and include 3 general types: random collisions, coincidental collisions, and collisions that result from attraction of bats to turbines. The random collision hypothesis posits that interactions between bats and turbines are random events and that fatalities are representative of the bats present at a site. Coincidental hypotheses posit that certain aspects of bat distribution or behavior put them at risk of collision and include aggregation during migration and seasonal increases in flight activity associated with feeding or mating. A surprising number of attraction hypotheses suggest that bats might be attracted to turbines out of curiosity, misperception, or as potential feeding, roosting, flocking, and mating opportunities. Identifying, prioritizing, and testing hypothesized causes of bat collisions with wind turbines are vital steps toward developing practical solutions to the problem.

The use of stable isotopes in such studies has several advantages over the use of radioisotopes, including cost, ease of handling, elimination of permit requirements, and waste disposal. A pilot study using brown trout was performed to evaluate sample preparation methods and the ability of a quadrupole inductively coupled plasma mass spectrometer (ICP-MS) system to successfully measure changes in the super(67)Zn/ super(66)Zn ratios for planned exposure levels and duration. After completion of the pilot study, a full-scale zinc exposure study using rainbow trout was performed. The results of these studies indicate that there are several factors that affect the precision of the measured super(67)Zn/ super(66)Zn ratios in the sample digests, including variations in sample size, endogenous zinc levels, and zinc uptake rates by individual fish. However, since these factors were incorporated in the calculation of the total zinc accumulated by the gills during the exposures, the data obtained were adequate for their intended use in calculating zinc binding and evaluating the influences of differences in water quality parameters.

Erodibility at the three sites was similar during the summer and fall. A site near the estuary mouth maintained this level of erodibility greater than 90% of the time while two sites in the more physically dominated mid-estuary region exhibited a consistent and pronounced increase in erodibility in the late winter and spring. Weak to non-existent correlations between bed erodibility, solids volume fraction, and surficial concentrations of organic matter, colloidal carbohydrate, and extracellular polymeric substances, were not sufficient to explain the observed seasonal pattern in bed erodibility. Digital X-radiographs revealed thick sequences (10-20+cm) of laminated sediments at the surface in the middle estuary coincident with the period of highest erodibility and more biologically reworked sediment during the rest of the year, suggesting that periodic rapid deposition introduced new sediment that was seasonally easy to erode. The finding that seasonal deposition influenced erodibility at the mid-estuary sites is consistent with previous results indicating the occasional presence of a secondary turbidity maximum. Comparison of the biologically reworked, but still ''low'' erodibility condition in the York to other published Chesapeake Bay erodibility data revealed a consistent critical shear stress range and profile, suggesting that this equilibrium critical stress profile may be representative of other similar estuarine environments in the absence of rapid deposition. At relatively low stresses and in the absence of rapid deposition, we speculate that burrowing and/or pelletization may play a role in maintaining high equilibrium bulk water content without reducing the strength of the surface of the seabed.

15323754 AB - It has been well documented that restored wetlands in the Prairie Pothole Region of North America do store carbon. However, the net benefit of carbon sequestration in wetlands in terms of a reduction in global warming forcing has often been questioned because of potentially greater emissions of greenhouse gases (GHGs) such as nitrous oxide (N sub(2O) and methane (CH) sub(4)). We compared gas emissions (N sub(2O, CH) sub(4), carbon dioxide [CO sub(2]) and soil moisture and temperature from eight cropland and eight restored grassland wetlands in the Prairie Pothole Region from May to October, 2003, to better understand the atmospheric carbon mitigation potential of restored wetlands. Results show that carbon dioxide contributed the most (90%) to net-GHG flux, followed by CH) sub(4) (9%) and N sub(2O (1%). Fluxes of N) sub(2)O, CH sub(4, CO) sub(2), and their combined global warming potential (CO sub(2 equivalents) did not significantly differ between cropland and grassland wetlands. The seasonal pattern in flux was similar in cropland and grassland wetlands with peak emissions of N) sub(2)O and CH sub(4 occurring when soil water-filled pore space (WFPS) was 40-60% and 60%, respectively; negative CH) sub(4) fluxes were observed when WFPS approached 40%. Negative CH sub(4 fluxes from grassland wetlands occurred earlier in the season and were more pronounced than those from cropland sites because WFPS declined more rapidly in grassland wetlands; this decline was likely due to higher infiltration and evapotranspiration rates associated with grasslands. Our results suggest that restoring cropland wetlands does not result in greater emissions of N) sub(2)O and CH sub(4, and therefore would not offset potential soil carbon sequestration. These findings, however, are limited to a small sample of seasonal wetlands with relatively short hydroperiods. A more comprehensive assessment of the GHG mitigation potential of restored wetlands should include a diversity of wetland types and land-use practices and consider the impact of variable climatic cycles that affect wetland hydrology.)

AN - 869592647; 14132702 AB - Few studies have investigated the relationship between morphological variation and local feeding habits of bats in the United States. We used discriminant function analysis (DFA) to compare cranial morphology of Myotis occultus from southern Colorado, and central, and southern New Mexico. We analyzed guano collected from maternity colonies in southern Colorado and central New Mexico to compare food habits. Bats from southern Colorado had the smallest values on the first canonical variate (CV1) that also reflected the smallest measurements of key cranial and dental variables, including height of coronoid process, width of molar, and dentary thickness. Bats from central and southern New Mexico had intermediate and large CV1 values, respectively. Overall, CV1 discriminated individuals occurring in southern Colorado and central New Mexico from those in southern New Mexico. CV2 served best at discriminating bats of southern Colorado from those of central New Mexico. Comparison of food habits revealed that individuals from southern Colorado ate more soft-bodied prey items (e.g., flies) whereas bats from central New Mexico ate more hard-bodied prey items (e.g., beetles). As shown in earlier studies that investigated relationships between morphology and diet of insectivorous bats, we found differences in skull morphology of M. occultus that were correlated with differences in food habits.

Bat occurrence was most closely associated with canopy cover, vegetation stature and distance to known roosts. The metrics generated by this study can serve as a quantitative baseline for future assessments of the status of this endangered species following changes in habitat due to management activities (e.g., feral goat control) or other factors (e.g., typhoon impacts). Additionally, we provide quantitative descriptions of the echolocation calls of E. semicaudata. Search-phase calls were characterized by a relatively narrow bandwidth and short pulse duration typical of insectivores that forage within vegetative clutter.

Widespread and expanding use of satellite tracking to study movements and habitats of marine megavertebrates warrants a review of progress to date and a discussion of challenges facing this rapidly evolving research field. To this end, we reviewed the satellite telemetry literature of air-breathing marine taxa (i.e. birds, mammals, turtles) over the 20 yr time period from 1987 to 2006. This review yielded 92 studies with a wide taxonomic representation: 47 seabirds, 23 sea turtles, and 22 marine mammals. Here we critically evaluate these articles to assess progress in satellite tracking of marine megavertebrates in terms of (1) objectives and approach, (2) experimental design, and (3) reporting of results. The overall trends revealed increases in the duration and scope of tracking studies, yet improvements on experimental design and reporting are needed to facilitate comparisons across studies and species. While inherent ecological differences influence the focus and methods of taxon-specific studies, this review highlights specific areas in need of improvement and provides general suggestions for future tracking studies of marine megavertebrates.

The stepped spillway has a few unique features, including the uniform, high velocity flow that enters the stepped section. The constant-sloped reach (s = 0.4) was studied in a sectional model using 2 different step heights to simulate the relative roughness near the design and maximum PMF discharge conditions. Tests under atmospheric conditions investigated loss characteristics as well as detailed pressure and velocity fields with the use of Particle Image Velocimetry (PIV). The model was then moved to the laboratory's LAPC where reduced ambient pressures allowed measurement of the inception point for cavitation with visualization using high speed video. Test results compared well with the Darcy friction factor and the incipient cavitation index was determined for unaerated flow on a constant-sloped stepped spillway of 1V:2.5H.

This project involved collecting acoustic Doppler current profiler data near the new intake (Intake No. 3) site in Lake Mead's Boulder Basin. A comprehensive understanding of seasonal reservoir currents in the vicinity of the new intake will allow SNWS operators to effectively operate their three intakes supplying raw water to their water treatment facilities. ADCP and water quality profiles were collected on a bimonthly schedule for a period of two years in an effort to document the seasonal reservoir current characteristics in the vicinity of the proposed intake. A summary of seasonal reservoir currents and water quality characteristics at the new intake site and other locations in Lake Mead are presented. For the period studied, current and water quality profile data indicate the new water intake is located at a favorable site and the new intake should meet the water quality objectives. In addition, selective withdrawal modeling was performed to predict raw water quality and the withdrawal zone characteristics. JF - Hydraulic Laboratory Report.

AN - 734126933; 18974941 AB - From 1977-1978 to 1990, concentrations of polychlorinated biphenyls (PCBs) and most organochlorine pesticides declined in eggs of red-breasted mergansers (Mergus serrator) nesting on islands in northwestern Lake Michigan. Further declines took place between 1990 and 2002. Between 1977-1978 and 1990 total PCBs decreased 60% (from 21 to 8.5 microg/g, wet weight). An additional decline of 46% took place between 1990 and 2002 (8.5 to 4.6 microg/g). Between 1977-1978 and 1990 p,p (')-DDE decreased 66% (from 6.5 to 2.2 microg/g), and from 1990 to 2002 an additional decline of 36% took place (from 2.2 to 1.4 microg/g). Between 1977-1978 and 1990 dieldrin decreased only 16% (from 0.82 to 0.69 microg/g), but from 1990 to 2002 a 96% decrease occurred (from 0.69 to 0.03 microg/g).

We examined the transferability of Escherichia coli and F super(+) coliphage (MS2) from beach sand to hands in order to estimate the potential subsequent health risk. Sand with high initial E. coli concentrations was collected from a Chicago beach. Individuals manipulated the sand for 60 seconds, and rinse water was analysed for E. coli and coliphage. E. coli densities transferred were correlated with density in sand rather than surface area of an individual's hand, and the amount of coliphage transferred from seeded sand was different among individuals. In sequential rinsing, percentage reduction was 92% for E. coli and 98% for coliphage. Using dose-response estimates developed for swimming water, it was determined that the number of individuals per thousand that would develop gastrointestinal symptoms would be 11 if all E. coli on the fingertip were ingested or 33 if all E. coli on the hand were ingested. These results suggest that beach sand may be an important medium for microbial exposure; bacteria transfer is related to initial concentration in the sand; and rinsing may be effective in limiting oral exposure to sand-borne microbes of human concern.

The strongest relations between fishes and urbanization occurred in the metropolitan areas of Atlanta, Georgia; Birmingham, Alabama; Boston, Massachusetts; and Portland, Oregon. In these areas, environmental variables with strong associations (r sub(s).0.70) with fish assemblages and fish traits tended to have strong associations with urbanization. Relations of urbanization with fish assemblages and fish traits were weaker in Denver, Colorado; Dallas-Fort Worth, Texas; Milwaukee-Green Bay, Wisconsin; and Raleigh, North Carolina. Environmental variables associated with fishes varied among the metropolitan areas. The metropolitan areas with poor relations may have had a limited range of possible response because of previous landscape disturbances. Given the complexities of urban landscapes in different metropolitan areas, our results indicate that caution is warranted when generalizing about biological responses to urbanization.

Analyses of the geophysical data and sediment cores along with age control provided by 34 AMS super(14)C dates on marine shells and wood reveal the following history. As sea level rose in the early Holocene, fluvial deposits filled the Apalachicola River paleochannel, which extended southward under the central part of the bay and seaward across the continental shelf. Sediments to either side of the paleochannel contain abundant wood fragments, with dates documenting that those areas were forested at 8,000 super(14)C years b.p. As sea level continued to rise, spits formed of headland prodelta deposits. Between 6,400 and 2,500 super(14)C years b.p., an Apalachicola prodelta prograded and receded several times across the inner shelf that underlies the western part of the bay. An eastern deltaic lobe was active for a shorter time, between 5,800 and 5,100 super(14)C years b.p. Estuarine benthic foraminiferal assemblages occurred in the western bay as early as 6,400 super(14)C years b.p., and indicate that there was some physical barrier to open-ocean circulation and shelf species established by that time. It is considered that shoals formed in the region of the present barrier islands as the rising sea flooded an interstream divide. Estuarine conditions were established very early in the post-glacial flooding of the bay.

From 11 April to 8 May 2008, Mississippi River water was diverted through the spillway into the 629-square-mile Lake Pontchartrain, which is hydraulically connected to the Gulf of Mexico. On 8 April, prior to the opening of the spillway, water-quality instruments were deployed and recorded hourly measurements of water temperature, dissolved oxygen, specific conductance, pH, and nitrate. Discrete water-quality and phytoplankton (algae) samples were collected in Lake Pontchartrain from 8 April to 3 October 2008 to assess the water-quality nutrient enrichment effects of the diversion on the lake. The maximum influence of river water in the southern portion of the lake was captured with continuous (hourly) monitoring of nitrate concentrations, and field measurements such as of specific conductance during the critical period in late April to early May. By late May, the deployed instruments had recorded the arrival, peak, and decline of selected constituents associated with the freshwater influx from the Mississippi River/Bonnet Carre Spillway diversion. The continuous monitoring data showed the short-term interactions of high-nitrate, low-specific conductance river water and low-nitrate, high-specific conductance lake water. The phytoplankton community composition, as an indicator of water quality, illustrated an extended response from the river water evident even after the continuous and discrete samples indicated that the lake had returned to pre-diversion conditions. The initial phytoplankton community response to nutrient increases was related to accumulations of diatoms. During periods of low nutrient concentrations, accumulations of blue-greens occurred by July and August. As blue-green algae cell densities and biovolumes increased in the summer, so did the species richness of blue-green algae, particularly the harmful algae bloom taxa. Cell densities and biovolume of the phytoplankton lake indicator taxa Skeletonema costatum, Anabaena sp., and Cylindrospermopsis raciborskii were highest and dominated the diatom and blue-green algae communities during the period of most river water influence on the lake and immediately following the freshwater inflows. The dominance and recession of these indictor taxa reflect the dramatic changes that occurred in the phytoplankton community in response to an increase in nutrient-rich freshwater from the diversion into the lake, and not normal seasonal phytoplankton compositional differences. Water-quality data indicated a gradual reversion to pre-diversion lake conditions by June to July, but shifts in the phytoplankton composition were still evident through August 2008. Observations from this study were similar to results from previous studies of Mississippi River/Bonnet Carre Spillway diversion opening in 1997.

Over time, herbivore populations fluctuate, producing great potential for spatio-temporal landscape dynamics. In this study, we extend the spatial and temporal extent of a long-term investigation of the relationship of landscape patterns to moose foraging behavior at Isle Royale National Park, MI. We examined how patterns of browse availability and consumption, plant basal area, and soil fertility changed during a recent decline in the moose population. We used geostatistics to examine changes in the nature of spatial patterns in two valleys over 18years and across short-range and long-range distance scales. Landscape patterns of available and consumed browse changed from either repeated patches or randomly distributed patches in 1988-1992 to random point distributions by 2007 after a recent record high peak followed by a rapid decline in the moose population. Patterns of available and consumed browse became decoupled during the moose population low, which is in contrast to coupled patterns during the earlier high moose population. Distributions of plant basal area and soil nitrogen availability also switched from repeated patches to randomly distributed patches in one valley and to random point distributions in the other valley. Rapid declines in moose population density may release vegetation and soil fertility from browsing pressure and in turn create random landscape patterns.

Video monitoring of 100 randomly chosen, permanent transects at five study sites in the US Virgin Islands revealed over 90% of the scleractinian coral cover showed signs of thermal stress by paling or becoming completely white. Lower water temperatures in October allowed some re-coloring of corals; however, a subsequent unprecedented regional outbreak of coral disease affected all sites. Five known diseases or syndromes were recorded; however, most lesions showed signs similar to white plague. Nineteen scleractinian species were affected by disease, with >90% of the disease-induced lesions occurring on the genus Montastraea. The disease outbreak peaked several months after the onset of bleaching at all sites but did not occur at the same time. The mean number of disease-induced lesions increased 51-fold and the mean area of disease-associated mortality increased 13-fold when compared with pre-bleaching disease levels. In the 12months following the onset of bleaching, coral cover declined at all sites (average loss: 51.5%, range: 42.4-61.8%) reducing the five-site average from 21.4% before bleaching to 10.3% with most mortality caused by white plague disease, not bleaching. Continued losses through October 2007 reduced the average coral cover of the five sites to 8.3% (average 2-year loss: 61.1%, range: 53.0-79.3%). Mean cover by M. annularis (complex) decreased 51%, Colpophyllia natans 78% and Agaricia agaricites 87%. Isolated disease outbreaks have been documented before in the Virgin Islands, but never as widespread or devastating as the one that occurred after the 2005 Caribbean coral-bleaching event. This study provides insight into the effects of continued seawater warming and subsequent coral bleaching events in the Caribbean and highlights the need to understand links between coral bleaching and disease.

We studied the effects of a temporary drawdown on shoreline vegetation communities of Felsenthal Navigation Pool ('the pool'), an impoundment at Felsenthal National Wildlife Refuge in southern Arkansas that is managed as a greentree reservoir. The pool was permanently flooded from 1985 until the summer of 1995 when the water level was dropped 0.3m for about 16weeks, exposing about 1,591ha of soil. To document plant succession on the sediments exposed, we recorded plant species composition and cover at 14 transects along the pool margin prior to the drawdown, during the drawdown, and in the following summer. A soil disturbance treatment was applied near five transects following the drawdown, and soil was collected at each transect for seed bank and soil analyses. Plants colonized the drawdown zone quickly and high vegetation cover was present at some transects 4weeks after the drawdown was initiated. Plants included species that are high quality food sources for waterfowl, including Cyperus erythrorhizos and Leptochloa fascicularis var. fascicularis. Vegetation response, measured by species richness, total cover, and cover of Cyperus species, was often greater at low compared to high elevations in the drawdown zone; this effect was probably intensified by low summer rainfall. Response on the disturbed transects was lower than that on the undisturbed transects. This effect was attributed to two factors: (1) removal of the existing seed bank by the disturbance applied and (2) reduced incorporation of seeds recruited during the drawdown because of unusually low rainfall. Seed bank studies demonstrated that several species persisted despite 10years of continual flooding, and that seed bank species richness increased during the drawdown. Although conclusions are limited by the 1-year time frame of the study, it is unlikely that permanent change to plant community structure in the drawdown zone resulted from the lowered water level.

We transferred age-1 hatchery fall Chinook salmon to net-pens in October 2005 and age-0 fall Chinook salmon in May 2006. Indices of smolt development were assessed in the hatchery and after 3 and 14 d in net-pens. Based on gill Na super(+), K super(+)-ATPase activity and plasma thyroxine (T4) concentration, age-1 Chinook salmon were not developing smolt characteristics in the hatchery during October. Fish transferred to the river or lake had increased plasma cortisol in response to stress and increased T4 accompanying the change in water, but they did not have altered development. Variables in the age-0 Chinook salmon indicated that the fish in the hatchery were smolting. The fish in the river net-pens lost mass and had gill ATPase activity similar to that of the fish in the hatchery, whereas the fish transferred to the lake gained mass and length, had reduced condition factor, and had higher gill ATPase than the fish in the river. These results, along with environmental variables, suggest that the conditions in the lake were more conducive to smoltification than those in the river and thus accelerated the development of Chinook salmon. No Chinook salmon in the hatchery or either net-pen became infected with the myxosporean parasite Ceratomyxa shasta (the presence of which in the river and lake was confirmed) during either trial or when held for 90 d after a 10-d exposure in net-pens (2006 group). We concluded that that there is little evidence of physiological impairment or significant upriver vulnerability to C. shasta among this stock of fall Chinook salmon that would preclude them from being reintroduced into the Upper Klamath River basin.

Effective management of this coastal area requires an understanding of the processes involved in shoreline erosion and measures that can be enacted to reduce loss. The dominant stratigraphy of the delta plain is fluvial mud (silts and clays), delivered in suspension via a series of shallow-water delta lobes that prograded across the shelf throughout the Holocene. Abandonment of a delta lobe through avulsion leads to rapid land subsidence through compaction within the muddy framework. As the deltaic headland subsides below sea level, the marine environment transgresses the bays and wetlands, reworking the available sands into transgressive barrier shorelines. This natural process is further complicated by numerous factors: (1) global sea-level rise; (2) reduced sediment load within the Mississippi River; (3) diversion of the sediment load away from the barrier shorelines to the deep shelf; (4) storm-induced erosion; and (5) human alteration of the littoral process through the construction of hardened shorelines, canals, and other activities. This suite of factors has led to the deterioration of the barrier-island systems that protect interior wetlands and human infrastructure from normal wave activity and periodic storm impact. Interior wetland loss results in an increased tidal prism and inlet cross-sectional areas, and expanding ebb-tidal deltas, which removes sand from the littoral processes through diversion and sequestration. Shoreface erosion of the deltaic headlands does not provide sufficient sand to balance the loss, resulting in thinning and dislocation of the islands. Abatement measures include replenishing lost sediment with similar material, excavated from discrete sandy deposits within the muddy delta plain. These sand bodies were deposited by the same cyclical processes that formed the barrier islands, and understanding these processes is necessary to characterize their location, extent, and resource potential. In this paper we demonstrate the dominant fluvial and marine-transgressive depositional processes that occur on the inner shelf, and identify the preservation and resource potential of fluvio-deltaic deposits for coastal management in Louisiana.

Monitoring and modeling studies have concluded that the expansion of the Louisiana shelf dead zone is related to increased anthropogenically derived nutrient delivery from the Mississippi River drainage basin, physical and hydrographical changes of the Louisiana Shelf, and possibly coastal erosion of wetlands in southern Louisiana. In order to track the development and expansion of seasonal low-oxygen conditions on the Louisiana shelf prior to 1985, we used a specific low-oxygen foraminiferal faunal proxy, the PEB index, which has been shown statistically to represent the modern Louisiana hypoxia zone. We constructed a network of 13 PEB records with excess super(210)Pb-derived chronologies to establish the development of low-oxygen and hypoxic conditions over a large portion of the modern dead zone for the last 100years. The PEB index record indicates that areas of low-oxygen bottom water began to appear in the early 1910s in isolated hotspots near the Mississippi Delta and rapidly expanded across the entire Louisiana shelf beginning in the 1950s. Since ~1950, the percentage of PEB species has steadily increased over a large portion of the modern dead zone. By 1960, subsurface low-oxygen conditions were occurring seasonally over a large part of the geographic area now known as the dead zone. The long-term trends in the PEB index are consistent with the 20th-century observational and proxy data for low oxygen and hypoxia.

In the wake of the devastating 2005 hurricane season, and in response to the complex management issues facing the region, the U.S. Geological Survey organized the multidisciplinary 'Northern Gulf of Mexico Ecosystem Change and Hazards Susceptibility' project. This special issue of Geo-Marine Letters hosts a few of the early results in the form of 11 papers covering three themes: (1) the control exerted by the underlying geologic framework on geomorphology and nearshore processes and features; (2) impact of human activities on nearshore water quality; and (3) hurricanes and associated effects.

Blood samples were obtained from 13,403 birds, representing 133 species. Specific WNV neutralizing antibody was detected in 254 resident and migratory birds, representing 39 species, and was most commonly detected in northern cardinals (Cardinalis cardinalis) (9.8%, N = 762) and gray catbirds (Dumetella carolinensis) (3.2%, N = 3188). West Nile virus viremias were detected in 19 birds, including 8 gray catbirds, and only during the fall migratory period. These results provide additional evidence that migratory birds may have been a principal agent for the spread of WNV in North America and provide data on the occurrence of WNV in a variety of bird species.

Diets of alewife or isolated strains of P. thiaminolyticus mixed in a semipurified diet and fed to lake trout Salvelinus namaycush have been shown to produce EMS in fry. We utilized quantitative polymerase chain reaction (Q-PCR) to aid in studies of the sources of P. thiaminolyticus and thiaminase I. Quantitative PCR assays were established to detect the thiaminase I gene of P. thiaminolyticus, the 16S rRNA gene from most species of bacteria, and the 16S rRNA gene specifically from P. thiaminolyticus and a few closely related taxa. The Q-PCR assays are linear over at least six orders of magnitude and can detect the thiaminase I gene of P. thiaminolyticus from as few as 1,000 P. thiaminolyticus cells/g of sample or the Paenibacillus 16S rRNA gene from as few as 100 P. thiaminolyticus cells/g of sample. The initial results from alewife viscera samples with high thiaminase activity yielded unexpectedly low densities of P. thiaminolyticus cells; Paenibacillus thiaminolyticus was detectable in 2 of 6 alewife viscera tested at densities on the order of 100 cells/g out of 100,000,000 total bacterial cells/g. The low numbers of P. thiaminolyticus detected suggest that alewives contain additional non-P. thiaminolyticus sources of thiaminase activity.

In this study, patch-scale rates of in-stream benthic processes were determined using large volume, open-bottom benthic incubation chambers in a nitrate-rich, first to third order stream draining an area dominated by tile-drained row-crop fields. The chambers were fitted with sampling/mixing ports, a volume compensation bladder, and porewater samplers. Incubations were conducted with added tracers (NaBr and either super(15)N[NO sub(3) super(-)], super(15)N[NO sub(2) super(-)], or super(15)N[NH sub(4) super(+)]) for 24-44h intervals and reaction rates were determined from changes in concentrations and isotopic compositions of nitrate, nitrite, ammonium and nitrogen gas. Overall, nitrate loss rates (220-3,560kmolNm super( -2)h super(-1) ) greatly exceeded corresponding denitrification rates (34-212kmolNm super(&#x 2212; 2)h super(-1)) and both of these rates were correlated with nitrate concentrations (90-1,330kM), which could be readily manipulated with addition experiments. Chamber estimates closely matched whole-stream rates of denitrification and nitrate loss using super(15)N. Chamber incubations with acetylene indicated that coupled nitrification/denitrification was not a major source of N sub(2) production at ambient nitrate concentrations (175kM), but acetylene was not effective for assessing denitrification at higher nitrate concentrations (1,330kM). Ammonium uptake rates greatly exceeded nitrification rates, which were relatively low even with added ammonium (3.5kmolNm super(-2) h super(-1)), though incubations with nitrite demonstrated that oxidation to nitrate exceeded reduction to nitrogen gas in the surface sediments by fivefold to tenfold. The chamber results confirmed earlier studies that denitrification was a substantial nitrate sink in this stream, but they also indicated that dissolved inorganic nitrogen (DIN) turnover rates greatly exceeded the rates of permanent nitrogen removal via denitrification.

We found that fry density had a significant effect on most response variables but that rearing treatment did not. The rates of threats and attacks were positively correlated with fry density, but the overall feeding rate was negatively correlated. Naturally reared fry were dominant more often at low densities, and hatchery-reared fry were dominant more often at high densities. There were no significant effects of hatchery rearing treatment on aggression, feeding, dominance, or territory size. The only significant effect of rearing treatment was on the position of naturally reared fry, which occupied more upstream positions when stocked with conventional than with enriched hatchery-reared fry. Overall, rearing environment had relatively little influence on the behavior of steelhead fry. Our results indicate that stocking hatchery-reared steelhead fry at low densities may have effects on similar-size wild fish comparable to an equivalent increase in the density of wild fish.

Biochemical characterization of the thiaminase I activities observed in forage fish was undertaken to provide insights into potential thiaminase sources and to optimize catalytic assay conditions. We measured the thiaminase I activities of crude extracts from five forage fish species and one strain of Paenibacillus thiaminolyticus over a range of pH values. The clupeids, alewife Alosa pseudoharengus and gizzard shad Dorosoma cepedianum, had very similar thiaminase I pH dependencies, with optimal activity ranges (.90% of maximum activity) between pH 4.6 and 5.5. Rainbow smelt Osmerus mordax and spottail shiner Notropis hudsonius had optimal activity ranges between pH 5.5-6.6. The thiaminase I activity pH dependence profile of P. thiaminolyticus had an optimal activity range between pH 5.4 and 6.3, which was similar to the optimal range for rainbow smelt and spottail shiners. Incubation of P. thiaminolyticus extracts with extracts from bloater Coregonus hoyi (normally, bloaters have little or no detectable thiaminase I activity) did not significantly alter the pH dependence profile of P. thiaminolyticus-derived thiaminase I, such that it continued to resemble that of the rainbow smelt and spottail shiner, with an apparent optimal activity range between pH 5.7 and 6.6. These data are consistent with the hypothesis of a bacterial source for thiaminase I in the nonclupeid species of forage fish; however, the data also suggest different sources of thiaminase I enzymes in the clupeid species.

The Salmon River is a high-quality spawning and nursery river for Pacific salmon (Oncorhynchus spp.) migrating from Lake Ontario. Because of the large number of Pacific salmon spawning in the river in the fall extensive redd superimposition occurs resulting in salmonid eggs being available on the substrate. We examined the fall diet of 647 fallfish in 2007 and 2008 to determine the extent of predation on Pacific salmon eggs. The contribution of eggs in the diet significantly increased once fallfish attained a size of 100 mm total length. The largest size category of fallfish examined (>= 150 mm) had the highest proportion (86.1%) of salmon eggs in their diet. The contribution of zooplankton and chironomids in the diet of fallfish decreased with fish size. Except for the two largest groups of fallfish examined (i.e., 100-149 mm and >= 150 mm) diet overlap among size groups was low. The high contribution in the diet during the fall and high caloric value of Pacific salmon eggs could increase growth and survival of this species in the Salmon River.

In this paper, we examine the status and trends of the land bird fauna of Saipan Island based on three island-wide surveys conducted in 1982, 1997, and 2007. During this period, the human population on Saipan increased more than four-fold and much of the island has been developed. The surveys employed standard point-transect methods based on Distance Sampling. Remarkably, we found nearly all species of land birds - 11 native species and three introduced species - to be common or abundant. The exception was the Micronesian Megapode Megapodius laperouse, a historically rare species that was not observed on the 2007 survey, although it does persist on Saipan and other Mariana islands. A comparison of species densities among the three surveys showed that seven species, mainly fruit and seed-eaters, had increased and three species of insectivorous birds had decreased - Rufous Fantail Rhipidura rufifrons, Nightingale Reed-warbler Acrocephalus luscinia, and Golden White-eye Cleptornis marchei. Of these three, Nightingale Reed-warbler is listed as 'Endangered' on the IUCN Red List and as an Endangered Species by the U.S. Fish and Wildlife Service. Reed-warbler densities on Saipan decreased by more than half between 1982 and 2007. Although point transect sampling worked well for this species, density estimates and trends assessment could be improved by reallocating sampling stations among habitats and by more frequent sampling.

Elevated water levels in the reservoir may increase flow of low-quality water from abandoned mine tunnels in the Sugarloaf District and degrade water quality downstream. The objective of this study was to understand the sources of water to Dinero mine drainage tunnel and evaluate whether or not there was a direct hydrologic connection between Dinero mine tunnel and Turquoise Lake from late 2002 to early 2008. This study utilized hydrograph data from nearby draining mine tunnels and the lake, and stable isotope (d super(18)O and d super(2)H) data from the lake, nearby draining mine tunnels, imported water, and springs to characterize water sources in the study area. Hydrograph results indicate that flow from the Dinero mine tunnel decreased 26% (2006) and 10% (2007) when lake elevation (above mean sea level) decreased below approximately 3004 m (approximately 9855 feet). Results of isotope analysis delineated two meteoric water lines in the study area. One line characterizes surface water and water imported to the study area from the western side of the Continental Divide. The other line characterizes groundwater including draining mine tunnels, springs, and seeps. Isotope mixing calculations indicate that water from Turquoise Lake or seasonal groundwater recharge from snowmelt represents approximately 10% or less of the water in Dinero mine tunnel. However, most of the water in Dinero mine tunnel is from deep groundwater having minimal isotopic variation. The asymmetric shape of the Dinero mine tunnel hydrograph may indicate that a limited mine pool exists behind a collapse in the tunnel and attenutates seasonal recharge. Alternatively, a conceptual model is presented (and supported with MODFLOW simulations) that is consistent with current and previous data collected in the study area, and illustrates how fluctuating lake levels change the local water-table elevation which can affect discharge from the Dinero mine tunnel without physical transfer of water between the two locations.

Between 1985 and 2004, 12.65 million lake trout were stocked into Lake Huron representing eight different genetic strains. Collections of bona fide wild fish in USGS surveys have increased in recent years and this study examined the ancestry and diet of fish collected between 2004 and 2006 to explore the ecological role they occupy in Lake Huron. Analysis of microsatellite DNA revealed that both pure strain and inter-strain hybrids were observed, and the majority of fish were classified as Seneca Lake strain or Seneca Lake hybrids. Diets of 50 wild age-0 lake trout were examined. Mysis, chironomids, and zooplankton were common prey items of wild age-0 lake trout. These results indicate that stocked fish are successfully reproducing in Lake Huron indicating a level of restoration success. However, continued changes to the benthic macroinvertebrate community, particularly declines of Mysis, may limit growth and survival of wild fish and hinder restoration efforts.

Larvae were collected with towed ichthyoplankton nets offshore and with larval seines along the shoreline. Larval feeding periodicity was examined from collections made at 4-h intervals over one 24-h period in 2005. Inter-annual variation in diet composition (% dry weight) was low, as was spatial variation among collection sites within the bay. Copepods (81.4%), primarily cyclopoids (59.1%), were the primary prey of larvae over the 3-year period. Cladocerans (8.1%; mainly daphnids, 6.7%) and chironomids (7.3%) were the other major prey consumed. Larvae did not exhibit a preference for any specific prey taxa. Food consumption of lake whitefish larvae was significantly lower at night (i.e., 2400 and 0400 h). Substantial variation in diet composition occurred over the 24-h diel study. For the 24-h period, copepods were the major prey consumed (50.4%) and their contribution in the diet ranged from 29.3% (0400 h) to 85.9% (1200 h).

Liver neoplasia AN - 21087282; 11267304 AB - Liver pathology of fishes, including neoplastic and preneoplastic lesions, is widely used as an indicator of exposure to anthropogenic contaminants. By definition, the "fish tumor or other deformities" beneficial use impairment (BUI) at Great Lakes Areas of Concern (AOC) includes neoplastic and preneoplastic liver lesions in brown bullhead (Ameiurus nebulosus) or suckers. Unfortunately, adequate guidelines for defining neoplastic and preneoplastic liver lesions or determining rates at unimpacted control sites were not provided and different criteria have been used. In some cases, only neoplastic changes were used to calculate tumor prevalence, in some both neoplastic and preneoplastic changes and in some it is difficult to determine which changes were included. Using standardized criteria, the prevalence of liver neoplasia was compared at eight AOC during 1998-2000. The Cuyahoga River had the highest prevalence (25.0%), while the Maumee River had the lowest (3.9%). The Buffalo (4.8%), Detroit (5.9%), Ashtabula (6.8%), Niagara (7.5%) and Black (8.9%) rivers were intermediate, as was Presque Isle Bay (7.1%). From 2002 to 2007 the prevalence of liver neoplasia at Presque Isle Bay ranged from a low of 2.1% (2002) to a high of 12.0% (2007). Non-AOC sites, as potential reference sites, also were monitored during this time. By combining years and sites, the prevalence of liver neoplasia in bullhead (aged 2 to 12 years) at inland lakes was 0.7%, at bays/harbors was 1.6% and at tributary sites was 4.1%. This is the same trend (inland lakes < bays/harbors < tributaries < Presque Isle Bay) noted for orocutaneous neoplasms.

However, take is seldom addressed in a quantitative or population modeling context and the criterion of ''jeopardy'' has no universal, quantitative definition. To model the effect of incidental take on population viability, we modified an existing population model and simulated abundance, population growth, and quasi-extinction probability (the probability of falling below a predetermined abundance threshold) for Piping Plovers (Charadrius melodus) in the Great Plains, USA. The model incorporated environmental stochasticity and variation due to sampling variance. Eggs and chicks were taken out of the population as a ''harvest'' to simulate incidental take that currently occurs in the Missouri River system. We used least-squares regression and an AIC model selection approach to evaluate the population's elasticity to incidental take covariates. Even in the absence of take the population declined by 7.5% annually. Population growth and final abundance were reduced and the probability of quasi-extinction was increased in simulations where egg take and chick take were applied. The model selection analysis indicated that incidental take of eggs and chicks depresses population viability and the probability of recovery of Piping Plovers in the Great Plains. Though the model was useful in putting take and jeopardy in a quantitative setting, the question remains as to whether permitted levels of take causes jeopardy for Piping Plovers since there are no decision standards defined by the USFWS. However, evaluating take in a quantitative framework, as we have, will make jeopardy decisions more explicit in terms of viability and recovery metrics.

Fishes were captured by angling, surgically implanted with radio transmitters, and tracked actively from June through September. Most brook trout (96%) and landlocked salmon (72%) displayed long distance movements (>1 km) to open water bodies (28 June to 4 July) followed by periods of time spent in presumed thermal refugia (5 July to 16 September). Summer water temperature rose above 25 C, near the reported lethal limits for these coldwater species. In contrast, the majority of smallmouth bass (68%), a warmwater species, did not make long distance movements from areas of initial capture, remaining in mainstem sections of the river (28 June to 16 September). Spatial overlap of smallmouth bass and brook trout in the summer is unlikely because brook trout presumably move to thermal refugia during this time. However, interspecific competition between brook trout and landlocked salmon may occur since they select similar habitats June through September.

Nonetheless, restoration managers lack simple decision-support tools for predicting shear stresses and sediment redistribution potential in different vegetation communities. Using a field-validated numerical model, we developed state-space diagrams that provide these predictions over a range of water-surface slopes, depths, and associated velocities in Everglades ridge and slough vegetation communities. Diminished bed shear stresses and a consequent decrease in bed sediment redistribution are hypothesized causes of a recent reduction in the topographic and vegetation heterogeneity of this ecosystem. Results confirmed the inability of present-day flows to entrain bed sediment. Further, our diagrams showed bed shear stresses to be highly sensitive to emergent vegetation density and water-surface slope but less sensitive to water depth and periphyton or floating vegetation abundance. These findings suggested that instituting a pulsing flow regime could be the most effective means to restore sediment redistribution to the Everglades. However, pulsing flows will not be sufficient to erode sediment from sloughs with abundant spikerush, unless spikerush density first decreases by natural or managed processes. Our methods provide a novel tool for identifying restoration parameters and performance measures in many types of vegetated aquatic environments where sediment erosion and deposition are involved.

Two lack-of-fit (LOF) indices were used to control the inverse modelling: sum of squares (SS) and an alternative statistic called the vertical-horizontal distance integrator (VHDI), which is designed to account for offsets in observed and predicted arrival times of peak IPU concentration. With these data, SS was artificially inflated because it is limited to comparison of predicted and observed IPU concentrations that are concurrent in time. The LOFs were used along with the index of agreement (d) and the correlation coefficient (r) to ascertain the fit of the calibrated models. RESULTS: Predicted arrival times of peak IPU concentration differed somewhat from observed times. All four indices indicated better model fit for the second of two validation periods when inverse modelling was controlled by VHDI rather than SS (SS = 26.4, d = 0.660, r = 0.606 and VHDI = 1.25). The VHDI statistic was markedly lower compared with the uncalibrated model (38.0) and SS calibration results (24.5). The final maximum predicted IPU concentration (44.5 ?g L-1) for the calibration period was very similar to the observed value (44 ?g L-1). CONCLUSION: VHDI is seen as an effective alternative to SS for calibration and validation of pesticide fate models applied to responsive systems. VHDI provided a more realistic assessment of model performance for the transient flows and short-lived concentrations observed here, and also effectively substituted for the objective function in inverse modelling.

In combination, the tracers indicate that runoff during a flood in August could have come from cultivated taro fields bordering the lower reach of the river. Land-based runoff associated with summer floods may have a greater impact on coral reef communities in Hanalei Bay than in winter because sediment persists for several months. During dry periods, sediment carried by the Hanalei River appears to have been mobilized primarily by undercutting of low super(7)Be, low super(1) super(3) super(7)Cs riverbanks composed of soil weathered from tholeiitic basalt with low Ba and Co concentrations. Following a moderate rainfall event in September, high super(7)Be sediment carried by the Hanalei River was probably mobilized by overland flow in the upper watershed. Ba-desorption in low-salinity coastal water limited its use to a qualitative runoff tracer in nearshore sediment. super(2) super(1) super(0)Pb had limited usefulness as a terrestrial tracer in the nearshore due to a large dissolved oceanic source and scavenging onto resuspended bottom sediment. super(2) super(1) super(0)Pb-scavenging does, however, illustrate the role resuspension could play in the accumulation of particle-reactive contaminants in nearshore sediment.

This model can be applied for cases where water temperature in a well or spring receives all or part of its water from a phreatic conduit. Heat transport in the conduit is simulated by using a physically-based heat-transport equation that accounts for inflow of diffuse flow from smaller openings and fissures in the surrounding aquifer during periods of low recharge. Additional diffuse flow that is within the zone of influence of the well or spring but has not interacted with the conduit is accounted for with a binary mixing equation to proportion these different water sources. The estimation of this proportion through inverse modeling is useful for the assessment of contaminant vulnerability and well-head or spring protection. The model was applied to 7months of continuous temperature data for a sinking stream that recharges a conduit and a pumped well open to the Madison aquifer in western South Dakota. The simulated conduit-flow fraction to the well ranged from 2% to 31% of total flow, and simulated conduit velocity ranged from 44 to 353m/d.

The MRA is the largest amplitude (13 nT) satellite magnetic anomaly over Canada. Within the extent of the MRA, source depth estimates (8-12 km) from Euler deconvolution of low-altitude aeromagnetic data show coincidence with basement depths interpreted from reflection seismic data. Inversion of high-altitude (3.5 km) aeromagnetic data produces an average magnetization of 2.5 A/m within a 15- to 35-km deep layer, a value typical of magmatic arc complexes. Early Proterozoic magmatic arc rocks have been sampled to the southeast of the MRA, within the Fort Simpson magnetic anomaly. The MRA is one of several broad-scale magnetic highs that occur along the inboard margin of the Cordillera in Canada and Alaska, which are coincident with geometric changes in the thrust front transition from the mobile belt to stable cratonic North America. The inferred early Proterozoic magmatic arc complex along the western edge of the North American craton likely influenced later tectonic evolution, by acting as a buttress along the inboard margin of the Cordilleran fold-and-thrust belt.

AQUI-S super(T) super(M) is a fish anesthetic /sedative approved for use in several countries and until recently was being developed in the U.S. as a sedative for immediate release of fish after sedation. The U.S. National Toxicology Program reported that isoeugenol (the active ingredient in AQUI-S super(T) super(M)) exposed male mice showed clear evidence of carcinogenicity, therefore efforts within the U.S. Department of Interior to develop AQUI-S super(T) super(M) as a sedative that allows for immediate release ceased. Despite the ruling, AQUI-S super(T) super(M) still has the potential to be approved as an anesthetic with a short withdrawal time. Among the data required to gain approval for use in the U.S. are data describing the composition and depletion of all AQUI-S super(T) super(M) residues from fish fillet tissue. A total residue depletion study for AQUI-S super(T) super(M) was conducted by exposing market-sized rainbow trout, Oncorhynchus mykiss (mean weight, 502.7+/-54g; s.d.) to 8.9mg/L of super(1) super(4)C-[URL]-isoeugenol for 60min in 17 super(o)C water. The super(1) super(4)C-[URL]-isoeugenol was mixed with a surfactant resulting in a mixture that mimicked AQUI-S super(T) super(M). Groups of fish (n=6) were sampled immediately after the exposure (0-h sample group) and at 0.5, 1, 2, and 4h thereafter. Total isoeugenol-equivalent residue concentrations in the fillet tissue were determined by oxidizing triplicate subsamples of homogenized skin-on fillet tissue from each fish to super(1) super(4)CO sub(2) and enumerating the radioactivity by static liquid scintillation counting. Isoeugenol concentrations in fillet tissue were determined by extracting homogenized fillet tissue with solvents and determining the isoeugenol concentrations in the extracts with high performance liquid chromatography techniques. The mean total isoeugenol-equivalent residue concentrations in the 0, 0.5, 1, 2, and 4-h sample groups were 55.4, 32.0, 19.8, 11.3, and 4.9?g/g, respectively. The primary chemical residue in fillet tissue from all exposed fish was isoeugenol. The mean isoeugenol concentrations in the 0, 0.5, 1, 2, and 4-h sample groups were 48.9, 26.5, 15.3, 7.2, and 2.2?g/g, respectively. The percents of the total radioactivity classified as isoeugenol in the 0, 0.5, 1, 2, and 4-h tissue extracts were 95, 73, 73, 64, and 48%, respectively.

AN - 734206015; 20028067 AB - Small fish are commonly used to assess mercury (Hg) risk to wildlife and monitor Hg in wetlands. However, limited research has evaluated short-term Hg variability in small fish, which can have important implications for monitoring programs and risk assessment. We conducted a time-series study of Hg concentrations in two small fish species representing benthic (longjaw mudsuckers [Gillichthys mirabilis]) and pelagic (threespine sticklebacks [Gasterosteus aculeatus]) food-webs within three wetland habitats in San Francisco Bay Estuary. We simultaneously monitored prey deliveries, nest initiation, and chick hatching dates of breeding Forster's terns (Sterna forsteri), the most abundant nesting piscivore in the region. Mudsuckers and sticklebacks were the predominant prey fish, comprising 36% and 25% of tern diet, and Hg concentrations averaged (geometric mean +/- SE, microg/g dw) 0.44 +/- 0.01 and 0.68 +/- 0.03, respectively. Fish Hg concentrations varied substantially over time following a quadratic form in both species, increasing 40% between March and May then decreasing 40% between May and July. Importantly, Forster's terns initiated 68% of nests and 31% of chicks hatched during the period of peak Hg concentrations in prey fish. These results illustrate the importance of short-term temporal variation in small fish Hg concentrations for both Hg monitoring programs and assessing wildlife risk.

Collection of pre- and post-remediation data sets generally followed the synoptic mass balance approach, in which numerous stream and inflow locations are sampled for the constituents of interest and estimates of streamflow are determined by tracer dilution. The comparison of pre- and post-remediation data sets is confounded by hydrologic effects and the effects of temporal variation. Hydrologic effects arise due to the relatively wet conditions that preceded the collection of pre-remediation data, and the relatively dry conditions associated with the post-remediation data set. This difference leads to a dilution effect in the upper part of the study reach, where pre-remediation concentrations were diluted by rainfall, and a source area effect in the lower part of the study reach, where a smaller portion of the watershed may have been contributing constituent mass during the drier post-remediation period. A second confounding factor, temporal variability, violates the steady-state assumption that underlies the synoptic mass balance approach, leading to false identification of constituent sources and sinks. Despite these complications, remedial actions completed in the Mineral Creek headwaters appear to have led to improvements in stream water quality, as post-remediation profiles of instream load are consistently lower than the pre-remediation profiles over the entire study reach for six of the eight constituents considered (aluminium, arsenic, cadmium, copper, iron, and zinc). Concentrations of aluminium, cadmium, copper, lead, and zinc remain above chronic aquatic-life standards, however, and additional remedial actions may be needed.

The median value of seepage measured at 24 locations was 24 cm/day, but seepage measured at specific sites ranged from -340 to +237 cm/day. Seepage also varied substantially over periods of hours to days and occasionally reversed direction in response to evolution of the sediment bed. Vertical hydraulic conductivity was related to seepage direction and was larger during upward seepage than during downward seepage; with differences ranging from 4 to 40% in areas of active sediment transport to more than an order of magnitude in areas where current was too slow to mobilize bed sediment. Seepage was poorly related to hydraulic gradient measured over vertical distances of 0·3 m and appeared to be opposite the hydraulic gradient at 18% of the locations where both parameters were measured. Results demonstrate the scale dependence of these measurements in coarse-grained hyporheic settings and indicate that hydraulic gradients should be determined over a much shorter vertical increment if used to indicate exchange across the sediment-water interface.

Risk evaluations guide design of infrastructure alterations or lead to potential changes in operations. Changes in climate may change the risk due to floods and therefore decisions to alter infrastructure with a life span of decades or longer may benefit from the use of climate projections as opposed to use of only historical observations. This manuscript presents a set of methods meant to support flood frequency evaluation based on current downscaled climate projections and the potential implications of changing flood risk on how evaluations are made. Methods are demonstrated in four case study basins: the Boise River above Lucky Peak Dam, the San Joaquin River above Friant Dam, the James River above Jamestown Dam, and the Gunnison River above Blue Mesa Dam. The analytical design includes three core elements: (1) a rationale for selecting climate projections to represent available climate projections; (2) generation of runoff projections consistent with climate projections using a process-based hydrologic model and temporal disaggregation of monthly downscaled climate projections into 6-h weather forcings required by the hydrologic model; and (3) analysis of flood frequency distributions based on runoff projection results. In addition to demonstrating the methodology, this paper also presents method choices under each analytical element, and the resulting implications to how flood frequencies are evaluated. The methods used reproduce the antecedent calibration period well. The approach results in a unidirectional shift in modeled flood magnitudes. The comparison between an expanding retrospective (current paradigm for flood frequency estimation) and a lookahead flood frequency approach indicate potential for significant biases in flood frequency estimation.

This federally listed endangered species is native to perennial lowland streams in a few watersheds in northern California. Field sampling occurred in Lagunitas and Olema creeks at seasonal intervals from February 2003 to November 2004. Ten glides, five pools, and five riffles served as fixed sampling reaches, with eight glides, four pools, and four riffles located in Lagunitas Creek and the remainder in Olema Creek. A total of 1773 S. pacifica was counted during this study, all of which were captured along vegetated banks in Lagunitas Creek. Syncaris pacifica was most numerous in glides (64%), then in pools (31%), and lastly in riffles (5%). According to logistic regression analysis, S. pacifica was mostly associated with submerged portions of streambank vegetation (especially overhanging vegetation such as ferns and blackberries, emergent vegetation such as sedge and brooklime, and fine roots associated with water hemlock, willow, sedge, and blackberries) along with low water current velocity and a sandy substrate. These seemingly favorable habitat conditions for S. pacifica were present in glides and pools in Lagunitas Creek, but not in Olema Creek.

It is unknown if these new flowers produce viable seeds by the end of the growing season. The purpose of this 2-yr study was to determine the appropriate timing (or timings) or combination (or combinations) of timings of defoliation on spotted knapweed to reduce its viable seed production. Spotted knapweed plants on foothill rangeland in west-central Montana were hand-clipped at seven different timings and frequencies of defoliation: June (bolting stage); July (late-bud-early flowering stage); August (full-flowering stage); June+July; June+August; July+August; or June+July+August. Unclipped plants were controls. Plants clipped in the bolting stage were defoliated at 35-40% relative utilization. Plants clipped at all other timings had 100% of their buds and flowers removed, plus 3 cm of each bud or flower stem. Plant response was evaluated from mid-August through September, whenever the seed heads of each treatment's plants reached maturity but while their seed-head bracts remained tightly closed. Clipping at any timing or combination of timings reduced the number of buds and flower heads per plant (P<0.01), number of seeds per plant (P<0.01), percentage of viability of seeds (P<0.01), and number of viable seeds per plant (P<0.01) compared with no clipping. Clipping during the bolting stage reduced the number of viable seeds by nearly 90% compared with no clipping. Clipping during the late-bud-early-flower or full-flower stage reduced the number of viable seeds by nearly 100% compared with no clipping. Spotted knapweed defoliation via prescribed sheep grazing or mowing in summer should suppress viable seed production of spotted knapweed.

AN - 860882291; 19572770 AB - The influence of dissolved organic carbon (DOC) and water composition on the toxicity of copper to juvenile freshwater mussels (fatmucket, Lampsilis siliquoidea) were evaluated in natural and reconstituted waters. Acute 96-h copper toxicity tests werec onducted at four nominal DOC concentrations (0, 2.5, 5, and 10 mg/L as carbon [C]) in dilutions of natural waters and in American Society for Testing and Materials (ASTM) reconstituted hard water. Toxicity tests also were conducted in ASTM soft, moderately hard, hard, and very hard reconstituted waters (nominal hardness 45-300 mg/L as CaCO₃). Three natural surface waters (9.5-11 mg/L DOC) were diluted to obtain a series of DOC concentrations with diluted well water, and an extract of natural organic matter and commercial humic acid was mixed with ASTM hard water to prepare a series of DOC concentrations for toxicity testing. Median effective concentrations (EC50s) for dissolved copper varied >40-fold (9.9 to >396 gg Cu/L) over all 21 treatments in various DOC waters. Within a particular type of DOC water, EC50s increased 5- to 12-fold across DOC concentrations of 0.3 to up to 11 mg C/L. However, EC50s increased by only a factor of 1.4 (21-30 gg Cu/L) in the four ASTM waters with wide range of water hardness (52-300 mg CaCO₃/L). Predictions from the biotic ligand model (BLM) for copper explained nearly 90% of the variability in EC50s. Nearly 70% of BLM-normalized EC50s for fatmucket tested in natural waters were below the final acute value used to derive the U.S. Environmental Protection Agency acute water quality criterion for copper, indicating that the criterion might not be protective of fatmucket and perhaps other mussel species.

We used stable isotope ratios ( super(13)C/ super(12)C, and super(15)N/ super(14)N) to characterize the trophic base of two streams in the Ozark Mountains of northwest Arkansas, U.S.A. We predicted that autochthonous resources would be more important during the spring and summer and allochthonous resources would be more important in the winter due to increased detritus inputs from the riparian zone during autumn leaf drop. We predicted that stream communities would demonstrate increased reliance on autochthonous resources at sites with larger watersheds and greater canopy openness. The study was conducted at three low-order sites in the Mulberry River Drainage (watershed area range: 81-232km super(2)) seasonally in 2006 and 2007. We used circular statistics to examine community-wide shifts in isotope space among fish and invertebrate consumers in relation to basal resources, including detritus and periphyton. Mixing models were used to quantify the relative contribution of autochthonous and allochthonous energy sources to individual invertebrate consumers. Significant isotopic shifts occurred but results varied by season and site indicating substantial variation in the trophic base of stream food webs. In terms of temporal variation, consumers shifted toward periphyton in the summer during periods of low discharge, but results varied during the interval between summer and winter. Our results did not demonstrate increased reliance on periphyton with increasing watershed area or canopy openness, and detritus was important at all the sites. In our study, riffle-pool geomorphology likely disrupted the expected spatial pattern and stream drying likely impacted the availability and distribution of basal resources.

Due to the sheer size of the affected areas, an unprecedented regional analysis at very high resolution and accuracy was needed to properly quantify and understand the effects of the hurricane and the storm tide. Many disparate sources of lidar data were acquired and processed for varying environmental reasons by pre- and post-Katrina projects. The datasets were in several formats and projections and were processed to varying phases of completion, and as a result the task of producing a seamless digital elevation dataset required a high level of coordination, research, and revision. To create a seamless digital elevation dataset, many technical issues had to be resolved before producing the desired 1/9-arc-second (3meter) grid needed as the map base for projecting the Katrina peak storm tide throughout the affected coastal region. This report presents the methodology that was developed to construct seamless digital elevation datasets from multipurpose, multi-use, and disparate lidar datasets, and describes an easily accessible Web application for viewing the maximum storm tide caused by Hurricane Katrina in southeastern Louisiana, Mississippi, and Alabama.

Accurate measurements of dune height and position are essential for assessing the vulnerability of beaches to extreme coastal change during future landfalls. Lidar topographic surveys provide rapid, accurate, high-resolution datasets for identifying the location, position, and morphology of coastal sand dunes over large stretches of coast. An algorithm has been developed for identification of the crest of the most seaward sand dune that defines the landward limit of the beach system. Based on changes in beach slope along cross-shore transects of lidar data, dune elevation and location can automatically be extracted every few meters along the coastline. Dune elevations in conjunction with storm-induced water levels can be used to predict the type of coastal response (e.g., beach erosion, dune erosion, overwash, or inundation) that may be expected during hurricane landfall. The vulnerability of the beach system at Fire Island National Seashore in New York to the most extreme of these changes, inundation, is assessed by comparing lidar-derived dune elevations to modeled wave setup and storm surge height. The vulnerability of the beach system to inundation during landfall of a Category 3 hurricane is shown to be spatially variable because of longshore variations in dune height (mean elevation = 5.44 m, standard deviation = 1.32 m). Hurricane-induced mean water levels exceed dune elevations along 70% of the coastal park, making these locations more vulnerable to inundation during a Category 3 storm.

OMWM includes a variety of hydrologic manipulations, often tailored to the specific conditions on individual marshes, so the overall effectiveness of this approach is difficult to assess. Here, we report the results of controlled field trials to assess the effects of two approaches to OMWM on larval mosquito production at National Wildlife Refuges (NWR). A traditional OMWM approach, using pond construction and radial ditches was used at Edwin B. Forsythe NWR in New Jersey, and a ditch-plugging approach was used at Parker River NWR in Massachusetts. Mosquito larvae were sampled from randomly placed stations on paired treatment and control marshes at each refuge. The proportion of sampling stations that were wet declined after OMWM at the Forsythe site, but not at the Parker River site. The proportion of samples with larvae present and mean larval densities, declined significantly at the treatment sites on both refuges relative to the control marshes. Percentage of control for the 2 yr posttreatment, compared with the 2 yr pretreatment, was >90% at both treatment sites.

Topography is a key parameter that influences many of the processes involved in coastal change, and thus, up-to-date, high-resolution, high-accuracy elevation data are required to model the coastal environment. Maps of areas subject to potential inundation have great utility to planners and managers concerned with the effects of sea-level rise. However, most of the maps produced to date are simplistic representations derived from older, coarse elevation data. In the last several years, vast amounts of high quality elevation data derived from lidar have become available. Because of their high vertical accuracy and spatial resolution, these lidar data are an excellent source of up-to-date information from which to improve identification and delineation of vulnerable lands. Four elevation datasets of varying resolution and accuracy were processed to demonstrate that the improved quality of lidar data leads to more precise delineation of coastal lands vulnerable to inundation. A key component of the comparison was to calculate and account for the vertical uncertainty of the elevation datasets. This comparison shows that lidar allows for a much more detailed delineation of the potential inundation zone when compared to other types of elevation models. It also shows how the certainty of the delineation of lands vulnerable to a given sea-level rise scenario is much improved when derived from higher resolution lidar data.

This roughness or topographic complexity is an important structural characteristic of reef habitats that affects a number of ecological and environmental attributes, including species diversity and water circulation. Little is known about the range of topographic complexity exhibited within a reef or between different reef systems. The objective of this study was to quantify topographic complexity for a 5-km x 5-km reefscape along the northern Florida Keys reef tract, over spatial scales ranging from meters to hundreds of meters. The underlying dataset was a 1-m spatial resolution, digital elevation model constructed from lidar measurements. Topographic complexity was quantified using a fractal algorithm, which provided a multi-scale characterization of reef roughness. The computed fractal dimensions (D) are a measure of substrate irregularity and are bounded between values of 2 and 3. Spatial patterns in D were positively correlated with known reef zonation in the area. Landward regions of the study site contain relatively smooth (D approximately 2.35) flat-topped patch reefs, which give way to rougher (D approximately 2.5), deep, knoll-shaped patch reefs. The seaward boundary contains a mixture of substrate features, including discontinuous shelf-edge reefs, and exhibits a corresponding range of roughness values (2.28 less than or equal to D less than or equal to 2.61).

In a transient integrated simulation of the water cycle, the time step size is a key factor in controlling the solution accuracy and the simulation efficiency for a given spatial discretization. In general, if the time step size is sufficiently small, the resulting solution becomes more accurate but with higher computational cost. Thus, to maintain an acceptable level of solution accuracy in the entire simulation domain, the time step size is restricted by the relatively rapid responses in the surface flow regime. As the relatively rapid responses are typically limited to a small portion of the surface domain compared with the groundwater system, a large portion of the domain tends to be temporally overdiscretized. The implicit subtime stepping approach described here can apply smaller subtime steps only to the subdomain where the accuracy requirements are needed. In this work, generalized formulations for implicit subtime stepping in the numerical solution of the nonlinear coupled surface-subsurface equations were derived and implemented into the integrated model HydroGeoSphere. Application to several problems showed that implicit subtime stepping can significantly improve the simulation efficiency with minimal loss in accuracy. The methodology was successfully applied to enhance the computational efficiency of an integrated flow simulation in the San Joaquin Valley, California, where the characteristic response time near surface drainage streams is orders of magnitude shorter than in the groundwater regime.

AN - 734115455; 19875791 AB - To determine more accurately the real-time concentration of fecal indicator bacteria (FIB) in beach water, predictive modeling has been applied in several locations around the Great Lakes to individual or small groups of similar beaches. Using 24 beaches in Door County, Wisconsin, we attempted to expand predictive models to multiple beaches of complex geography. We examined the importance of geographic location and independent variables and the consequential limitations for potential beach or beach group models. An analysis of Escherichia coli populations over 4 yr revealed a geographic gradient to the beaches, with mean E. coli concentrations decreasing with increasing distance from the city of Sturgeon Bay. Beaches grouped strongly by water type (lake, bay, Sturgeon Bay) and proximity to one another, followed by presence of a storm or creek outfall or amount of shoreline enclosure. Predictive models developed for beach groups commonly included wave height and cumulative 48-h rainfall but generally explained little E. coli variation (adj. R2=0.19-0.36). Generally low concentrations of E. coli at the beaches influenced the effectiveness of model results presumably because of low signal-to-noise ratios and the rarity of elevated concentrations. Our results highlight the importance of the sensitivity of regressors and the need for careful methods evaluation. Despite the attractiveness of predictive models as an alternative beach monitoring approach, it is likely that FIB fluctuations at some beaches defy simple prediction approaches. Regional, multi-beach, and individual beach predictive models should be explored alongside other techniques for improving monitoring reliability at Great Lakes beaches.

AN - 733668915; 19777152 AB - Clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) is a pyridine herbicide frequently used to control invasive, noxious weeds in the northwestern United States. Clopyralid exhibits low acute toxicity to fish, including the rainbow trout (Oncorhynchus mykiss) and the threatened bull trout (Salvelinus confluentus). However, there are no published chronic toxicity data for clopyralid and fish that can be used in ecological risk assessments. We conducted 30-day chronic toxicity studies with juvenile rainbow trout exposed to the acid form of clopyralid. The 30-day maximum acceptable toxicant concentration (MATC) for growth, calculated as the geometric mean of the no observable effect concentration (68 mg/L) and the lowest observable effect concentration (136 mg/L), was 96 mg/L. No mortality was measured at the highest chronic concentration tested (273 mg/L). The acute:chronic ratio, calculated by dividing the previously published 96-h acutely lethal concentration (96-h ALC(50); 700 mg/L) by the MATC was 7.3. Toxicity values were compared to a four-tiered exposure assessment profile assuming an application rate of 1.12 kg/ha. The Tier 1 exposure estimation, based on direct overspray of a 2-m deep pond, was 0.055 mg/L. The Tier 2 maximum exposure estimate, based on the Generic Exposure Estimate Concentration model (GEENEC), was 0.057 mg/L. The Tier 3 maximum exposure estimate, based on previously published results of the Groundwater Loading Effects of Agricultural Management Systems model (GLEAMS), was 0.073 mg/L. The Tier 4 exposure estimate, based on published edge-of-field monitoring data, was estimated at 0.008 mg/L. Comparison of toxicity data to estimated environmental concentrations of clopyralid indicates that the safety factor for rainbow trout exposed to clopyralid at labeled use rates exceeds 1000. Therefore, the herbicide presents little to no risk to rainbow trout or other salmonids such as the threatened bull trout.

The Kamchatka Volcanic Eruption Response Team (KVERT) monitors and reports on volcanic hazards to aviation for Kamchatka and the north Kuriles. KVERT scientists utilize real-time seismic data, daily satellite views of the region, real-time video, and pilot and field reports of activity to track and alert the aviation industry of hazardous activity. Most Kurile Island volcanoes are monitored by the Sakhalin Volcanic Eruption Response Team (SVERT) based in Yuzhno-Sakhalinsk. SVERT uses daily moderate resolution imaging spectroradiometer (MODIS) satellite images to look for volcanic activity along this 1,250-km chain of islands. Neither operation is staffed 24 h per day. In addition, the vast majority of Russian volcanoes are not monitored seismically in real-time. Other challenges include multiple time-zones and language differences that hamper communication among volcanologists and meteorologists in the US, Japan, and Russia who share the responsibility to issue official warnings. Rapid, consistent verification of explosive eruptions and determination of cloud heights remain significant technical challenges. Despite these difficulties, in more than a decade of frequent eruptive activity in Kamchatka and the northern Kuriles, no damaging encounters with volcanic ash from Russian eruptions have been recorded.

Utilizing loose-dumped spoil, in accordance with the Forestry Reclamation Approach (FRA), has demonstrated success with regards to promoting tree growth and survival; however, additional information is needed to assess the potential of FRA to ameliorate other environmental concerns related to water quantity. To better understand the hydrologic characteristics of loose-dumped spoil, key hydrograph parameters (discharge volume, peak discharge, discharge duration, lag time, and response time) were monitored for three common spoil types: (1) predominately brown weathered sandstone, (2) predominately gray weathered sandstone, and (3) a mixture of both sandstones and shale. Although spoil types were found to differ hydrologically, these differences were relatively minor. Measured discharge volumes were low (averaging 12% of rainfall for all events and treatments), peak discharge rates were small (between 2.5X10 (super -5) and 3X10 (super -3) m (super 3) /s), and the duration of discharge was long (6 days on average). From a hydrologic perspective, the results of this study indicate that mine spoils need not be segregated for reclamation as long as the spoil is placed in accordance with the loose-dumped techniques as outlined in the FRA.

The exposure of aviation to potential hazards from volcanoes in the United States is significant. In support of existing interagency operations to detect and track volcanic-ash clouds, the United States has prepared a National Volcanic Ash Operations Plan for Aviation to strengthen the warning process in its airspace. The US National Plan documents the responsibilities, communication protocols, and prescribed hazard messages of the Federal Aviation Administration, National Oceanic and Atmospheric Administration, US Geological Survey, and Air Force Weather Agency. The plan introduces a new message format, a Volcano Observatory Notice for Aviation, to provide clear, concise information about volcanic activity, including precursory unrest, to air-traffic controllers (for use in Notices to Airmen) and other aviation users. The plan is online at http://www.ofcm.gov/p35-nvaopa/pdf/FCM-P35-2007-NVAOPA.pdf. While the plan provides general operational practices, it remains the responsibility of the federal agencies involved to implement the described procedures through orders, directives, etc. Since the plan mirrors global guidelines of the International Civil Aviation Organization, it also provides an example that could be adapted by other countries.

Analysis of a new compilation of incidents of airports impacted by volcanic activity from 1944 through 2006 reveals that, at a minimum, 101 airports in 28 countries were affected on 171 occasions by eruptions at 46 volcanoes. Since 1980, five airports per year on average have been affected by volcanic activity, which indicates that volcanic hazards to airports are not rare on a worldwide basis. The main hazard to airports is ashfall, with accumulations of only a few millimeters sufficient to force temporary closures of some airports. A substantial portion of incidents has been caused by ash in airspace in the vicinity of airports, without accumulation of ash on the ground. On a few occasions, airports have been impacted by hazards other than ash (pyroclastic flow, lava flow, gas emission, and phreatic explosion). Several airports have been affected repeatedly by volcanic hazards. Four airports have been affected the most often and likely will continue to be among the most vulnerable owing to continued nearby volcanic activity: Fontanarossa International Airport in Catania, Italy; Ted Stevens Anchorage International Airport in Alaska, USA; Mariscal Sucre International Airport in Quito, Ecuador; and Tokua Airport in Kokopo, Papua New Guinea. The USA has the most airports affected by volcanic activity (17) on the most occasions (33) and hosts the second highest number of volcanoes that have caused the disruptions (5, after Indonesia with 7). One-fifth of the affected airports are within 30km of the source volcanoes, approximately half are located within 150km of the source volcanoes, and about three-quarters are within 300km; nearly one-fifth are located more than 500km away from the source volcanoes. The volcanoes that have caused the most impacts are Soufriere Hills on the island of Montserrat in the British West Indies, Tungurahua in Ecuador, Mt. Etna in Italy, Rabaul caldera in Papua New Guinea, Mt. Spurr and Mt. St. Helens in the USA, Ruapehu in New Zealand, Mt. Pinatubo in the Philippines, and Anatahan in the Commonwealth of the Northern Mariana Islands (part of the USA). Ten countries-USA, Indonesia, Ecuador, Papua New Guinea, Italy, New Zealand, Philippines, Mexico, Japan, and United Kingdom-have the highest volcanic hazard and/or vulnerability measures for airports. The adverse impacts of volcanic eruptions on airports can be mitigated by preparedness and forewarning. Methods that have been used to forewarn airports of volcanic activity include real-time detection of explosive volcanic activity, forecasts of ash dispersion and deposition, and detection of approaching ash clouds using ground-based Doppler radar. Given the demonstrated vulnerability of airports to disruption from volcanic activity, at-risk airports should develop operational plans for ashfall events, and volcano-monitoring agencies should provide timely forewarning of imminent volcanic-ash hazards directly to airport operators.

We compared concentrations of total and forms of P at various depths in cores collected before and after the onset of a large Aphanizomenon flos-aquae bloom. Concentrations of inorganic P were determined in extraction solutions of MgCl sub(2) (1M, pH8), citrate-dithionite-bicarbonate, and 1M HCl. Sediments below 2cm were dominated by residual P which is defined as total P minus inorganic P. During the study period, data from the top 2-cm of sediment indicated (a) significant decrease in total P concentration, primarily associated with iron oxyhydroxides at one site, and (b) significant increase in total P concentration associated with residual P at a second site. Data from two other sites indicated no net changes in concentrations of total P.

In the western United States, restoration of salinized land, particularly in river valleys, often involves control of Tamarix, an introduced species with high salinity tolerance. Revegetation of hydrologically disconnected floodplains and terraces after Tamarix removal is often difficult because of limited knowledge regarding the salinity tolerance of candidate native species for revegetation. Additionally, Tamarix appears to be non-mycorrhizal. Extended occupation of Tamarix may deplete arbuscular mycorrhizal fungi in the soil, further decreasing the success of revegetation efforts. To address these issues, we screened 42 species, races, or ecotypes native to southwestern U.S. for salinity tolerance and mycorrhizal responsiveness. As expected, the taxa tested showed a wide range of responses to salinity and mycorrhizal fungi. This variation also occurred between ecotypes or races of the same species, indicating that seed collected from high-salinity reference systems is likely better adapted to harsh conditions than seed originating from less saline environments. All species tested had a positive or neutral response to mycorrhizal inoculation. We found no clear evidence that mycorrhizae increased salinity tolerance, but some species were so dependent on mycorrhizal fungi that they grew poorly at all salinity levels in pasteurized soil.

Soft water has been said to cause the bursting of Asian carp eggs and thus has been suggested as a factor that would limit the spread of this species. To evaluate this, we subjected fertilized eggs of bighead carp to waters with a wide range of hardness and dissolved-solid concentrations. Hatching rate and egg size were not significantly affected by the different water qualities. These results, combined with the low hardness (28-84 mg/L) of the Yangtze River (the primary natal habitat of Hypophthalmichthys spp.), suggest that managers and those performing risk assessments for the establishment of Hypophthalmichthys spp. should be cautious about treating low hardness and dissolved-solid concentrations as limiting factors.

The widely used criteria of 8-12 C underestimated lake trout habitat use by 68%-80%. Instead, combined temperature (4 or 6 mg.L super(-1)) criteria most closely matched lake trout habitat use, had a similar seasonal trend as the tagged fish, suggested modest reductions (5% of total lake volume) in habitat during a warmer year, and performed best when the constraints of temperature and DO were most limiting. All data were collected in a small boreal shield lake (27 ha, z sub(max) = 21 m) at the Experimental Lakes Area in northwestern Ontario, Canada, during two contrasting periods of thermal stratification (2003: warmer and longer; 2004: cooler and shorter), providing an assessment of observed and theoretical habitat volumes over current environmental extremes.Original Abstract: Nous comparons les volumes theoriques de l'habitat determines a l'aide des combinaisons traditionnelles des limites de temperature et de concentrations d'oxygene dissous (DO) a l'utilisation de l'habitat sur place par des touladis (Salvelinus namaycush) porteurs d'etiquettes acoustiques. Le critere largement utilise de 8-12 C sous-estime l'utilisation de l'habitat du touladi de 68 % - 80 %. En contraste, les criteres combines de temperature (4 ou 6 mg.L super(-1)) s'ajustent le mieux a l'utilisation de l'habitat par les touladis, montrent les memes tendances saisonnieres que les poissons marques, indiquent des reductions modestes (5 % du volume total du lac) de l'habitat durant les annees plus chaudes et fonctionnent le mieux lorsque les contraintes de temperature et de DO sont les plus limitantes. Toutes les donnees proviennent d'un petit lac boreal du Bouclier canadien (27 ha, z sub(max) = 21 m) de la Region des lacs experimentaux dans le nord-ouest de l'Ontario, Canada, durant deux periodes tres differentes de stratification thermique (2003 : plus chaude et plus longue; 2004 : plus fraiche et plus courte), ce qui fournit une evaluation des volumes des habitats theoriques et observes dans les conditions environnementales extremes du moment.

A SUTRA-based solute-transport model was developed to test the hydraulic implications of a sequence-stratigraphic model of the Dominguez Gap area and to assess the effects of water-management scenarios. The model is two-dimensional, vertical and follows an approximate flow line extending from the Pacific Ocean through the Dominguez Gap area. Results indicate that a newly identified fault system can provide a pathway for transport of seawater and that a stratigraphic boundary located between the Bent Spring and Upper Wilmington sequences may control the vertical movement of seawater. Three 50-year water-management scenarios were considered: (1) no change in water-management practices; (2) installation of a slurry wall; and (3) raising inland water levels to 7.6m above sea level. Scenario 3 was the most effective by reversing seawater intrusion. The effects of an instantaneous 1-m sea-level rise were also tested using water-management scenarios 1 and 3. Results from two 100-year simulations indicate that a 1-m sea-level rise may accelerate seawater intrusion for scenario 1; however, scenario 3 remains effective for controlling seawater intrusion.Original Abstract: L'exploitation des eaux souterraines a conduit a un declin important du niveau piezometrique ainsi qu' a une intrusion d'eau de mer au niveau de la zone cotiere de Los Angeles, Californie (Etats-Unis d'Amerique). Un modele de transport de solutes (SUTRA) a ete developpe afin de tester les consequences hydrauliques d'un modele base sur la stratigraphie sequentielle au niveau de la zone de Dominguez Gap et d'evaluer les effets de scenarios de gestion de la ressource en eau. Le modele est un modele bidimensionnel vertical et suit une ligne d'ecoulement entre l'Ocean Pacifique et la zone de Dominguez Gap. Les resultats indiquent qu'un systeme de failles recemment identifie joue un role dans le transport de l'eau de mer et qu'une limite stratigraphique situee entre les sequences stratigraphiques de Bent Spring et de la partie superieure de Wilmington peut controler les mouvements verticaux de l'eau de mer. Trois scenarios de gestion de l'eau pour une duree de 50 ans ont ete analysees : (1) pas de changement dans les pratiques actuelles de gestion de la ressource, (2) installation d'une paroi d'etancheite et (3) augmentation du niveau d'eau continental de7.6m au dessus du niveau de la mer. Le troisieme scenario est le scenario qui a ete juge le plus efficace pour proceder a une inversion du processus d'intrusion saline. Les effets d'une augmentation instantanee de 1m du niveau de l'ocean ont egalement ete testes, en utilisant les scenarios A et 3. Les resultats de deux simulations pour une periode d'un siecle indiquent qu'une augmentation d'un metre du niveau de la mer a pour consequence une acceleration des intrusions salines pour le scenario 1, alors que le scenario 3 permet de garder le controle les intrusions d'eau de mer.El bombeo de las aguas subterraneas ha conducido a extensos descensos del nivel freatico y la intrusion de agua de mar en la costa de Los Angeles, California (EEUU).Un modelo (SUTRA) basado en el transporte de solutos fue desarrollado para probar las implicancias hidraulicas de un modelo de secuencia estratigrafica del area de Dominguez Gap para evaluar los efectos de los escenarios de manejo del agua. El modelo es bidimensional, vertical y sigue una linea aproximada de flujo que se extiende desde el Oceano Pacifico a traves del area Dominguez Gap. Los resultados indican que un sistema de fallas recientemente identificado puede proveer una via para el transporte de agua de mar y que el limite estratigrafico localizado entre las secuencias Bent Spring y Wilmington superior puede controlar el movimiento vertical del agua de mar. Se consideraron tres escenarios de cincuentas anos de manejo del agua: (1) sin cambios en las practicas de manejo del agua; (2) instalacion de una pantalla de hormigon; y (3) elevacion tierra adentro de los niveles de agua a 7.6m por encima del nivel del mar. El escenario 3 fue el mas efectivo para revertir la intrusion de agua de mar. Los efectos de un aumento instantaneo del nivel del mar de 1m tambien fueron testedos usando los escenarios de manejo del agua 1 y 3. Los resultados de dos simulaciones de 100 anos indican que el ascenso de 1m del nivel del mar puede acelerar la intrusion de agua de mar para el escenario 1, sin embargo, el escenario 3 permanece efectivo para controlar la intrusion de agua de mar.c34ae[frac12]ae¾ ; kSUTRAe[iquest], , , e[iquest]',e34"e[iquest]&# x0090; ae34>aa34", ae[frac12]Bent SpringWilmingtone34[sup1e[iquest]&#x 00E4; 34>50 : (1) ; (2) c[frac12]+ ; (3) ae[frac12]7.6m3e[frac12][not 4; 34k13, 1 maa[frac12]c100, 11 mae34k, 3ae34kA bombagem de agua subterranea tem levado a grandes rebaixamentos nos niveis de agua e a intrusao marinha no litoral de Los Angeles, California (EUA). Foi implementado um modelo de transporte de solutos baseado no modelo SUTRA para testar as implicacoes hidraulicas de um modelo de sequencia estratigrafica na area de Dominguez Gap e para avaliar os efeitos de diversos cenarios de gestao de agua. O modelo e bi-dimensional, vertical, e segue uma linha aproximada de fluxo que se estende desde o Oceano Pacifico, atravessando a area de Dominguez Gap. Os resultados indicam que um novo sistema de falhas agora identificado pode fornecer um caminho para o transporte da agua marinha, e que um limite estratigrafico situado entre as sequencias de Bent Spring e Upper Wilmington pode controlar o movimento vertical da agua do mar. Foram considerados tres cenarios de gestao de agua para periodos de 50 anos: (1) sem alteracoes nas praticas de gestao de agua; (2) instalacao de uma parede moldada; e (3) elevacao dos niveis das aguas interiores ate 7.6m acima do nivel do mar. O cenario 3 foi o mais eficaz, por conseguir inverter a intrusao marinha. Tambem se testaram os efeitos de uma subida instantanea de 1m do nivel do mar usando os cenarios de gestao de agua 1 e 3. Os resultados de duas simulacoes para 100 anos indicam que uma subida de 1m do nivel do mar pode acelerar a intrusao marinha para o Cenario 1; no entanto, o Cenario 3 mantem-se eficaz no controlo da mesma.

Such information can guide the location and timing of conservation efforts. Thus, we examined spring migration routes, chronology, and stopover use of 85 surf scoters (Melanitta perspicillata (L., 1758)) marked with satellite transmitters at four Pacific Flyway wintering sites: San Quintin Bay, Baja California; San Francisco Bay, California; Puget Sound, Washington; and Strait of Georgia, British Columbia. Eighty-three percent of marked scoters followed two main routes to the breeding area: a Southern Inland route involving staging in Puget Sound and Strait of Georgia and protracted inland migration, or a Northern Coastal route characterized by short movements along the Pacific coast of British Columbia and southeast Alaska with inland migration initiating from Lynn Canal and surrounding areas. Route choice was related to nesting site latitude in the Canadian Northern Boreal Forest. Data from birds tracked over 2 years indicated strong migration route fidelity, but altered chronology and stopover locations between years. Departure date varied by wintering site, but arrival and apparent settling dates were synchronous, suggesting individuals adjusted migration timing to meet an optimized reproductive schedule.Original Abstract: La comprehension de l'interconnectivite entre les zones d'hivernage, d'arret et de reproduction chez les oiseaux migrateurs est essentielle si l'on veut voir comment les evenements qui se passent dans chacune de ces zones peuvent avoir un effet lors d'une autre saison dans une autre zone. De telles informations pourraient orienter le choix des sites et du moment des interventions de conservation. Nous avons ainsi examine les routes printanieres de migration, leur chronologie et l'utilisation des points d'arret chez 85 macreuses a front blanc (Melanitta perspicillata (L., 1758)) munies d'emetteurs satellites a quatre sites d'hivernage sur la route de migration du Pacifique, la baie de San Quintin en Basse-Californie, la baie de San Francisco en Californie, Puget Sound au Washington et le detroit de Georgie en Colombie-Britannique. Quatre-vingt trois pourcent des macreuses marquees suivent deux voies principales vers la zone de reproduction, une route du sud dans l'interieur des terres comportant des arrets a Puget Sound et au detroit de Georgie avec une migration prolongee a l'interieur des terres et une route cotiere du nord caracterisee par de courts deplacements le long de la cote de la Colombie-Britannique et du sud-est de l'Alaska et une migration a l'interieur des terres debutant au canal de Lynn et les environs. Le choix de route depend de la latitude du site de nidification dans la foret boreale du nord du Canada. Des donnees obtenues d'oiseaux marques au cours de deux annees indiquent une forte fidelite a la route de migration, mais la chronologie de la migration et les sites d'arret peuvent changer d'une annee a l'autre. La date de depart varie en fonction du site d'hivernage, mais les dates d'arrivee et d'installation apparente sont synchronisees, ce qui laisse croire que les individus ajustent la chronologie de leur migration afin d'obtenir un calendrier optimal de reproduction.

Simultaneous decreases in super(1) super(4)C and increases in d super(1) super(8)O in non-El Nino shells are followed by constant super(1) super(4)C and gradually decreasing d super(1) super(8)O, which we interpret as evidence for discrete marine upwelling events followed by warming of the initially cold upwelled water. Upwelling changes from El Nino events are detectable with difficulty in mollusk shell super(1) super(4)C.

AN - 21077088; 11074369 AB - Plant populations may adapt to environmental conditions over time by developing genetically based morphological or physiological characteristics. For tidal freshwater forested wetlands, we hypothesized that the conditions under which trees developed led to ecotypic difference in response of progeny to hydroperiod. Specifically, we looked for evidence of ecotypic adaptation for tidal flooding at different salinity regimes using growth and ecophysiological characteristics of two tidal and two non-tidal source collections of baldcypress (Taxodium distichum (L.) L.C. Rich) from the southeastern United States. Saplings were subjected to treatments of hydrology (permanent versus tidal flooding) and salinity (0 versus [not, vert, similar]2 g l super(-1)) for two and a half growing seasons in a greenhouse environment. Saplings from tidal sources maintained 21-41% lower overall growth and biomass accumulation than saplings from non-tidal sources, while saplings from non-tidal sources maintained 14-19% lower overall rates of net photosynthetic assimilation, leaf transpiration, and stomatal conductance than saplings from tidal sources. However, we found no evidence for growth or physiological enhancement of saplings from tidal sources to tide, or of saplings from non-tidal sources to no tide. All saplings growing under permanent flooding exhibited reduced growth and leaf gas exchange regardless of source, with little evidence for consistent salinity effects across hydroperiods. While we reject our original hypothesis, we suggest that adaptations of coastal baldcypress to broad (rather than narrow) environmental conditions may promote ecophysiological and growth enhancements under a range of global-change-induced stressors, perhaps reflecting a natural resilience to environmental change while precluding adaptations for specific flood regimes.

The Pacific Ocean is particularly important in this respect because of its dominant role in exporting heat and moisture from the tropics to higher latitudes. Through targeting groundwaters in the Mojave Desert, California, we show that noble gas derived temperatures in California averaged 4.2 +/- 1.1 cooler in the Late Pleistocene (from [not, vert, similar]43 to [not, vert, similar]12 ka) compared to the Holocene (from [not, vert, similar]10 to [not, vert, similar]5 ka). Furthermore, the older groundwaters contain higher concentrations of excess air (entrained air bubbles) and have elevated oxygen-18/oxygen-16 ratios (d super(18)O) - indicators of vigorous aquifer recharge, and greater rainfall amounts and/or more intense precipitation events, respectively. Together, these paleoclimate indicators reveal that cooler and wetter conditions prevailed in the Mojave Desert from [not, vert, similar]43 to [not, vert, similar]12 ka. We suggest that during the Late Pleistocene, the Pacific ocean/atmosphere state was similar to present-day el Nino-like patterns, and was characterized by prolonged periods of weak trade winds, weak upwelling along the eastern Pacific margin, and increased precipitation in the southwestern U.S. JF - Quaternary Science Reviews AU - Kulongoski, J T AU - Hilton AU - Izbicki, JA AU - Belitz, K AD - U.S. Geological Survey, California Water Science Center, San Diego, CA 92101, USA, kulongos@usgs.gov Y1 - 2009/11// PY - 2009 DA - Nov 2009 SP - 2465 EP - 2473 PB - Elsevier Science, The Boulevard Kidlington Oxford OX5 1GB UK VL - 28 IS - 23-24 SN - 0277-3791, 0277-3791 KW - Oceanic Abstracts; Ecology Abstracts; ASFA 2: Ocean Technology Policy & Non-Living Resources; Water Resources Abstracts; Meteorological & Geoastrophysical Abstracts KW - ISEW, Pacific KW - Aquifers KW - Upwelling KW - Palaeo studies KW - Climate change KW - Indicators KW - Atmosphere KW - Holocene KW - Paleoclimates KW - Palaeoceanography KW - INE, USA, California KW - I, Pacific KW - Ground water KW - Ocean-atmosphere system KW - Paleoceanography KW - Temperature effects KW - Marine KW - Rare gases KW - Atmospheric gases KW - Temperature KW - Precipitation KW - Palaeoclimate KW - Oxygen isotopes KW - USA, California, Mojave Desert KW - Rainfall amount KW - Last Glacial Maximum KW - Aquifer recharge KW - Heat KW - Deserts KW - Oceans KW - Pleistocene KW - Groundwater KW - Q2 09243:Structure, mechanics and thermodynamics KW - O 2010:Physical Oceanography KW - M2 551.583:Variations (551.583) KW - SW 0815:Precipitation KW - D 04050:Paleoecology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/21070457?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Aecology&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Quaternary+Science+Reviews&rft.atitle=Evidence+for+prolonged+el+Nino-like+conditions+in+the+Pacific+during+the+Late+Pleistocene%3A+a+43+ka+noble+gas+record+from+California+groundwaters&rft.au=Kulongoski%2C+J+T%3BHilton%3BIzbicki%2C+JA%3BBelitz%2C+K&rft.aulast=Kulongoski&rft.aufirst=J&rft.date=2009-11-01&rft.volume=28&rft.issue=23-24&rft.spage=2465&rft.isbn=&rft.btitle=&rft.title=Quaternary+Science+Reviews&rft.issn=02773791&rft_id=info:doi/10.1016%2Fj.quascirev.2009.05.008 LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2009-11-01 N1 - Last updated - 2014-05-05 N1 - SubjectsTermNotLitGenreText - Rare gases; Atmospheric gases; Palaeoceanography; Deserts; Palaeo studies; Ocean-atmosphere system; Pleistocene; Palaeoclimate; Holocene; Temperature effects; Aquifers; Heat; Oceans; Ground water; Precipitation; Atmosphere; Oxygen isotopes; Rainfall amount; Aquifer recharge; Upwelling; Last Glacial Maximum; Climate change; Paleoceanography; Paleoclimates; Temperature; Indicators; Groundwater; ISEW, Pacific; USA, California, Mojave Desert; INE, USA, California; I, Pacific; Marine DO - http://dx.doi.org/10.1016/j.quascirev.2009.05.008 ER - TY - JOUR T1 - Bayesian inference in camera trapping studies for a class of spatial capture--recapture models AN - 21037448; 11325094 AB - We develop a class of models for inference about abundance or density using spatial capture-recapture data from studies based on camera trapping and related methods. The model is a hierarchical model composed of two components: a point process model describing the distribution of individuals in space (or their home range centers) and a model describing the, observation of individuals in traps. We suppose that trap- and individual-specific capture probabilities are a function of distance between individual home range centers and trap locations. We show that the models can be regarded as generalized linear mixed models, where the individual home range centers are random effects. We adopt a Bayesian framework for inference under these models using a formulation based on data augmentation. We apply the models to camera trapping data on tigers from the Nagarahole Reserve, India, collected over 48 nights in 2006. For this study, 120 camera locations were used, but cameras were only operational at 30 locations during any given sample occasion. Movement of traps is common in many camera-trapping studies and represents an important feature of the observation model that we address explicitly in our application.

The enantiomer fractions (EFs) measured in these samples are in good agreement with those reported for sediment, soil, and air samples in previous studies. The chlordane EFs were generally close to the racemic value of 0.5, with CC values ranging from 0.493 to 0.527 (usually >0.5) and TC values from 0.463 to 0.53 (usually <0.5). EF changes with core depth were detected for TC and CC in some cores, with the most non-racemic values near the top of the core. Surficial and suspended sediments generally have EF values similar to the top core layers but are often more non-racemic, indicating that enantioselective degradation is occurring before soils are eroded and deposited into bottom sediments. We hypothesize that rapid losses (desorption or degradation) from suspended sediments of the more bioavailable chlordane fraction during transport and initial deposition could explain the apparent shift to more racemic EF values in surficial and top core sediments. Near racemic CC and TC in the core profiles suggest minimal alteration of chlordane from biotic degradation, unless it is via non-enantioselective processes. EF values for the heptachlor degradate, heptachlor epoxide (HEPX), determined in surficial sediments from one location only were always non-racemic (EF0.66), were indicative of substantial biotic processing, and followed reported EF trends.

We investigated linkages between landscapes and assemblages in 31 wadeable Piedmont streams in the Etowah River basin in northern Georgia (USA). Our objectives were to identify the indicators of macroinvertebrate and fish integrity from a large set of best land cover (n=45), geomorphology (n=115), and water quality (n=12) variables, and to evaluate the potential for variables measured with minimal cost and effort to effectively predict biotic integrity. Macroinvertebrate descriptors were better predicted by land cover whereas fish descriptors were better predicted by geomorphology. Water quality variables demonstrated moderate levels of predictive power for biotic descriptors. Macroinvertebrate descriptors were best predicted by urban cover (-), conductivity (-), fines in riffles (-), and local relief (+). Fish descriptors were best predicted by embeddedness (-), turbidity (-), slope (+), and forest cover (+). We used multiple linear regression modeling to predict descriptors using three independent variable sets that varied in difficulty of data collection. ''Full'' models included a full range of geomorphic, water quality and landscape variables regardless of the intensity of data collection efforts. ''Reduced'' models included GIS-derived variables describing catchment morphometry and land use as well as variables easily collected in the field with minimal cost and effort. ''Simple'' models only included GIS-derived variables. Full models explained 63-81% of the variation among descriptors, indicating strong relationships between landscape properties and biotic assemblages across our sites. Reduced and simple models were weaker, explaining 48-79% and 42-79%, respectively, of the variance among descriptors. Considering the difference in predictive power among these model sets, we recommend a tiered approach to variable selection and model development depending upon management goals. GIS variables are simple and inexpensive to collect, and a GIS-based modeling approach would be appropriate for goals such as site screening (e.g., identification of reference streams). As management goals become more complex (e.g., long-term monitoring programs), additional, easily collected field variables (e.g., embeddedness) should be included. Finally, labor-intensive variables (e.g., nutrients and fines in sediments) could be added to meet complex management goals such as restoration of impaired streams or mechanistic studies of land use effects on stream ecosystems.

The IMS/ATP method concentrates target bacteria by immunomagnetic separation and then quantifies captured bacteria by measuring bioluminescence induced by release of ATP from the bacterial cells. Results from this method are available within 1h from the start of sample processing. Significant linear correlations were found between the IMS/ATP results and results from traditional culture-based methods for E. coli and enterococci enumeration for one location in California, two locations in North Carolina, and one location in Ohio (r values ranged from 0.87 to 0.97). No significant linear relation was found for a second location in California that treats a complex mixture of residential and industrial wastewater. With the exception of one location, IMS/ATP showed promise as a rapid method for the quantification of faecal-indicator organisms in wastewater.

Testicular oocytes (predominantly male testes containing female germ cells) were the most pervasive form of intersex observed, even though similar numbers of male (n=1477) and female (n=1633) fish were examined. Intersex was found in 3% of the fish collected. The intersex condition was observed in four of the 16 species examined (25%) and in fish from 34 of 111 sites (31%). Intersex was not found in multiple species from the same site but was most prevalent in largemouth bass (Micropterus salmoides; 18% of males) and smallmouth bass (M. dolomieu; 33% of males). The percentage of intersex fish per site was 8-91% for largemouth bass and 14-73% for smallmouth bass. The incidence of intersex was greatest in the southeastern United States, with intersex largemouth bass present at all sites in the Apalachicola, Savannah, and Pee Dee River Basins. Total mercury, trans-nonachlor, p,p'-DDE, p,p'-DDD, and total PCBs were the most commonly detected chemical contaminants at all sites, regardless of whether intersex was observed. Although the genotype of the intersex fish was not determined, the microscopic appearance of the gonads, the presence of mature sperm, and the concentrations of sex steroid hormones and vitellogenin indicate the intersex bass were males. Few reproductive endpoints differed significantly among male and intersex bass; plasma vitellogenin concentration in males was not a good indicator of intersex presence. Hierarchical linkages of the intersex condition to reproductive function will require a more quantitative measure of intersex (e.g. severity index) rather than presence or absence of the condition. The baseline incidence of intersex gonadal tissue in black basses and other freshwater fishes is unknown, but intersex prevalence may be related to collection season, age, and endocrine active compounds in the environment. Intersex was not found in largemouth bass older than five years and was most common in 1-3-year-old male largemouth bass. The cause(s) of intersex in these species is also unknown, and it remains to be determined whether the intersex we observed in largemouth and smallmouth bass developed during sex differentiation in early life stages, during exposure to environmental factors during adult life stages, or both.

When populations are near carrying capacity (K) or when they are declining due to reduced prey resources, the average age at 1st reproduction (average AFR) is predicted to be older than in populations below K. Differences between the trajectories of northern sea otter (Enhydra lutris kenyoni) populations in Alaska provides an opportunity to examine phenotypic plasticity. Using premolar teeth or reproductive tracts, we estimated average AFR from demographically distinct populations of sea otters in Alaska. We obtained samples from 2 populations near K, Prince William Sound (PWS) and the Aleutian Archipelago (archived samples), and from 2 populations below K, the Kodiak Archipelago and Sitka. The average AFR was lower in populations below K (3.60 years plus or minus 0.16 SD) compared to those near K (4.21 plus or minus 0.13 years, P < 0.001), and differed among all populations, with the Aleutian population possessing the oldest average AFR (4.29 plus or minus 0.09 years) followed by PWS (4.05 plus or minus 0.24 years), Sitka (3.80 plus or minus 0.21 years), and Kodiak (3.19 plus or minus 0.37 years). The difference in average AFR among populations supports life-history theory and provides evidence of phenotypic plasticity in sea otters. Our findings highlight the value of using average AFR as a tool for monitoring mammalian populations.

The framework of a quasi-transient convolution model that is applicable to two-domain flow in karst aquifers is presented. The model was designed to provide an acceptable level of statistical confidence in parameter estimates when only chlorofluorocarbon (CFC) and tritium ( super(3)H) data are available. We show how inverse modeling and uncertainty assessment can be used to constrain model parameterization to a level warranted by available data while allowing major aspects of the flow system to be examined. As an example, the model was applied to water from a pumped well open to the Madison aquifer in central USA with input functions of CFC-11, CFC-12, CFC-113, and super(3)H, and was calibrated to several samples collected during a 16-year period. A bimodal age distribution was modeled to represent quick and slow flow less than 50years old. The effects of pumping and hydraulic head on the relative volumetric fractions of these domains were found to be influential factors for transient flow. Quick flow and slow flow were estimated to be distributed mainly within the age ranges of 0-2 and 26-41years, respectively. The fraction of long-term flow (>50years) was estimated but was not dateable. The different tracers had different degrees of influence on parameter estimation and uncertainty assessments, where super(3)H was the most critical, and CFC-113 was least influential.

Since the Middle Pleistocene, eruption of ~350km super(3) of basalt through rhyolite has produced a 30km, arc front chain of nested calderas and overlapping stratovolcanoes. ELVC has experienced as many as five major caldera-forming eruptions, the most recent, at ~27ka, produced ~50km super(3) of rhyolitic ignimbrite and ash fall. These violent silicic events were interspersed with less energetic, but prodigious, outpourings of basalt through dacite. Holocene eruptions are mostly basaltic andesite to andesite and historically recorded activity includes over 40 eruptions within the last 200yr, all from Pavlof volcano, the most active site in the Aleutian Arc. Geochemical and geophysical observations suggest that although all ELVC eruptions derive from a common clinopyroxene+spinel+plagioclase fractionating high-aluminum basalt parent in the lower crust, magma follows one of two closely spaced, but distinct paths to the surface. Under the eastern end of the chain, magma moves rapidly and cleanly through a relatively young (~28ka), hydraulically connected dike plexus. Steady supply, short magma residence times, and limited interaction with crustal rocks preserve the geochemistry of deep crustal processes. Below the western part of the chain, magma moves haltingly through a long-lived (~500ka) and complex intrusive column in which many generations of basaltic to andesitic melts have mingled and fractionated. Buoyant, silicic melts periodically separate from the lower parts of the column to feed voluminous eruptions of dacite and rhyolite. Mafic lavas record a complicated passage through cumulate zones and hydrous silicic residues as manifested by disequilibrium phenocryst textures, incompatible element enrichments, and decoupling of REEs and HFSEs ratios. Such features are absent in mafic lavas from the younger part of the chain, highlighting the importance of plumbing architecture and longevity in creating petrologic diversity. Supplemental Data include 156 major element (XRF) and 128 trace element (ICP-MS) whole-rock analyses, 23 new super(4) super(0)Ar/ super(3) super(9)Ar ages, a generalized geologic map with associated unit descriptions and field photographs, and photomicrographs of key petrographic features.

Here we examine the effects of almost a century of sediment supply reduction from the damming of the Elwha River in Washington on shoreline position and beach morphology of its wave-dominated delta. The mean rate of shoreline erosion during 1939-2006 is 0.6 m/yr, which is equivalent to ~24,000 m super(3)/yr of sediment divergence in the littoral cell, a rate approximately equal to 25-50% of the littoral-grade sediment trapped by the dams. Semi-annual surveys between 2004 and 2007 show that most erosion occurs during the winter with lower rates of change in the summer. Shoreline change and morphology also differ spatially. Negligible shoreline change has occurred updrift (west) of the river mouth, where the beach is mixed sand to cobble, cuspate, and reflective. The beach downdrift (east) of the river mouth has had significant and persistent erosion, but this beach differs in that it has a reflective foreshore with a dissipative low-tide terrace. Downdrift beach erosion results from foreshore retreat, which broadens the low-tide terrace with time, and the rate of this kind of erosion has increased significantly from 0.8 m/yr during 1939-1990 to 1.4 m/yr during 1990-2006. Erosion rates for the downdrift beach derived from the 2004-2007 topographic surveys vary between 0 and 13 m/yr, with an average of 3.8 m/yr. We note that the low-tide terrace is significantly coarser (mean grain size ~100 mm) than the foreshore (mean grain size ~30 mm), a pattern contrary to the typical observation of fining low-tide terraces in the region and worldwide. Because this cobble low-tide terrace is created by foreshore erosion, has been steady over intervals of at least years, is predicted to have negligible longshore transport compared to the foreshore portion of the beach, and is inconsistent with oral history of abundant shellfish collections from the low-tide beach, we suggest that it is an armored layer of cobble clasts that are not generally competent in the physical setting of the delta. Thus, the cobble low-tide terrace is very likely a geomorphological feature caused by coastal erosion of a coastal plain and delta, which in turn is related to the impacts of the dams on the Elwha River to sediment fluxes to the coast.

To identify the relevant methane evolution pathways in the northern Cascadia accretionary margin, a four-site transect was drilled during Integrated Ocean Drilling Program Expedition 311. The d super(1) super(3)C values of methane range from a minimum value of -82.2%% on an uplifted ridge of accreted sediment near the deformation front (Site U1326, 1829mbsl, meters below sea level) to a maximum value of -39.5%% at the most landward location within an area of steep canyons near the shelf edge (Site U1329, 946mbsl). An interpretation based solely on methane isotope values might conclude the super(1) super(3)C-enrichment of methane indicates a transition from microbially- to thermogenically-sourced methane. However, the co-existing CO sub(2) exhibits a similar trend of super(1) super(3)C-enrichment along the transect with values ranging from -22.5%% to +25.7%%. The magnitude of the carbon isotope separation between methane and CO sub(2) (e sub(c)=63.8+/-5.8) is consistent with isotope fractionation during microbially mediated carbonate reduction. These results, in conjunction with a transect-wide gaseous hydrocarbon content composed of >99.8% (by volume) methane and uniform dD sub(C) sub(H) sub(4) values (-172%%+/-8) that are distinct from thermogenic methane at a seep located 60km from the Expedition 311 transect, suggest microbial CO sub(2) reduction is the predominant methane source at all investigated sites. The magnitude of the intra-site downhole super(1) super(3)C-enrichment of CO sub(2) within the accreted ridge (Site U1326) and a slope basin nearest the deformation front (Site U1325, 2195mbsl) is 5%%. At the mid-slope site (Site U1327, 1304mbsl) the downhole super(1) super(3)C-enrichment of the CO sub(2) is ~25%% and increases to ~40%% at the near-shelf edge Site U1329. This isotope fractionation pattern is indicative of more extensive diagenetic alteration at sites with greater super(1) super(3)C-enrichment. The magnitude of the super(1) super(3)C-enrichment of CO sub(2) correlates with decreasing sedimentation rates and a diminishing occurrence of stratigraphic gas hydrate. We suggest the decreasing sedimentation rates increase the exposure time of sedimentary organic matter to aerobic and anaerobic degradation, during burial, thereby reducing the availability of metabolizable organic matter available for methane production. This process is reflected in the occurrence and distribution of gas hydrate within the northern Cascadia margin accretionary prism. Our observations are relevant for evaluating methane production and the occurrence of stratigraphic gas hydrate within other convergent margins.

In mid-1975 a large pulse in sulfur and carbon dioxide output was observed both in emission rates and in fumarole samples. Emission rates of CO sub(2) and H sub(2)S were [not, vert, similar] 950 and 112 t/d, respectively, in 1975; these decreased to [not, vert, similar] 150 and 7 R sub(c)/R sub(A)), but has declined slightly since the mid-1970s, and delta super(13)C-CO sub(2) has decreased by >= 1ppt over time. Both trends are expected from a gradually crystallizing magma. While other scenarios are investigated, we conclude that magma intruded the mid- to shallow-crust beneath Mount Baker during the thermal awakening of 1975. Since that time, evidence for fresh magma has waned, but the continued emission of CO sub(2) and the presence of a long-term hydrothermal system leads us to suspect some continuing connection between the surface and deep convecting magma.

One-third of the salt and nearly all the Se in the Upper Colorado River (UCR) at Cisco, Utah, are directly attributed to weathering of the Cretaceous Mancos Shale. In 2005, a total of 1.4 Mt salt and 60 t Se were transferred from Mancos landscapes to the UCR above Cisco. This study investigated how and when solutes move from a Mancos landscape in the Uncompahgre watershed into the UCR. The Uncompaghre River is a tributary to the UCR in southwest Colorado, and over 60% of its annual salt load and 100% of its Se load are derived from natural weathering and irrigation of the Mancos. Rock and derived soil from a trenched weathering profile were chemically and mineralogically analyzed, and the Uncompahgre River water composition was measured during high-water, irrigation, and base flow regimes. Multiple chemical changes occur during weathering of the Mancos. At the onset, iron sulfide minerals oxidize to form gypsum with a unique isotopic composition (delta (super 34) S = -20ppm) that enabled the tracking of solutes. Progressive weathering leaches this gypsum (14% in shale to 4% in soil), Ca exchanges for Na on the clays, and Na (sub 2) SO (sub 4) phases form in the soil. Selenium in unweathered shale resides in pyrite, rare clausthalite (PbSe), and possibly organic matter. Oxidation converts primary, reduced Se to selenate, which is stored as a component of sulfate salts. The amount of Se extracted by water decreases with increasing weathering (40% in the shale compared to 13% in soil), indicating that the metal is labile during early weathering and is continually lost from the weathering profile. During weathering of shale to soil, several elements are depleted: Ca 50%; Na 55%; S 10%; C (sub CO3) 40%; and Se 65%. The amount of Mancos-derived salt and Se that entered the Uncompahgre River in 2005 and was transported downstream to the UCR is 375 t/d and 10 kg/d during high water flow (spring), 1180 t/d and 580 kg/d during irrigation season (summer), and 760 t/d and 11 kg/d during base flow (winter). Similar high rates of transfer were observed in all Mancos Shale watersheds and are influenced by changes in land use and seasonal weathering.

LiDAR data also aid in distinguishing possible tectonic geomorphic features from similar features with a nontectonic origin (e.g., landslides, moraine crests). Our study of potential Quaternary tectonic features along the east flank of the Gore Range is an example of utilizing LiDAR data. Although aerial photographs had been examined, many potential late Quaternary tectonic features were not recognized until LiDAR data were available; fault scarps and lineaments that cannot be detected on stereo aerial photographs can be readily visible using bare earth LiDAR data. The LiDAR survey completed for our study covered about 620 km (super 2) of densely vegetated mixed terrain, including steep slopes, and produced data for all returns, including bare earth. The average point spacing was 1.57 m, average point density was 0.41/m (super 2) , and area/point was 2.47 m (super 2) . Hillshade images of the data were created in ArcGIS, and hillshades with various sun azimuths and altitudes were used by themselves and superimposed to highlight and define geomorphic features with various orientations. The goal of our study is to evaluate evidence for late Quaternary tectonic activity on the northwest-striking, 45-km-long Gore Range frontal fault, located on the eastern flank of the Gore Range. To do this, we used bare earth LiDAR data to: 1) map the surficial geology, including glacial landforms and landslides, in the Gore Range adjacent to the fault; and 2) identify lineaments and scarps that could indicate late Quaternary fault surface rupture. Using LiDAR imagery, we identified at least 9 areas with possible fault scarps that cut glacial deposits of possibly two ages. These scarps, which are being examined during ground surveys, could have been produced during the late Quaternary, and may include some with post-Pinedale displacement (within the last approximately 10,000-12,000 years). The identified scarps are currently being investigated in the field using qualitative and quantitative dating, geomorphic interpretations, and scarp profile measurement.

Of the approximately 60 geochemically distinct obsidian groups that have been identified, only about 10 have a confirmed geological source, and a major thrust of our work has been the identification of the geological sources for these "unknown" geochemical groups. In this paper we describe the major obsidian sources for the region, provide a status report on efforts to correlate archaeological specimens to outcrops, and recommend a standardized terminology for source locations and geochemical groups. Key findings include: 1) A small number of obsidian sources were used intensively and the obsidian from them transported widely; the three most commonly used sources (Batza Tena, Okmok, and Wiki Peak) account for 81% of all analyzed samples. 2) Most obsidian sources in Alaska were used lightly and the obsidian from them transported only locally; at least 42 sources are represented by fewer than 10 archaeological samples each. 3) The process of prehistoric obsidian source location was fast and efficient; within a given region (e.g., Central Alaska, Aleutian Islands, Southeast Alaska), prehistoric people identified all of the common obsidian sources and some of the rare sources concurrent with its initial settlement. 4) Contrary to the notion of Beringia as a crossroads of cultures and hub of cultural interaction we have identified very few examples of Russian obsidian in Alaska and there are no known cases of Alaskan obsidian in Russian archaeological collections.

Although mining in the area began over 100 years ago, the most extensive production was from open pit mining and heap leach cyanide processing that occurred from 1977 until 1998 when the operator declared bankruptcy and the site was taken over by the U.S. Bureau of Land Management and the Montana Department of Environmental Quality. This paper details the history and management of mine drainage issues at the site from the first recognition that acidic drainage was a problem, through initial characterization and prediction work, to final reclamation and water treatment. Closure costs to date include approximately US$42M for material handling, grading, soil placement and vegetation, and approximately US$15M for construction, operation, and maintenance of water treatment facilities. Work continues on residual impacts many of which were not fully recognized until well into the closure phase. These include characterization and treatment strategies for acid mine drainage in Swift Gulch, a small stream whose headwaters originate on the mine property and which eventually flows onto adjacent tribal lands JF - Abstracts with Programs - Geological Society of America AU - Williams, R David AU - Shaw, Shannon AU - Jepson, Wayne E AU - Gammons, Christopher H AU - Kill Eagle, John L AU - Anonymous Y1 - 2009/10// PY - 2009 DA - October 2009 SP - 558 PB - Geological Society of America (GSA), Boulder, CO VL - 41 IS - 7 SN - 0016-7592, 0016-7592 KW - United States KW - mining KW - mines KW - acid mine drainage KW - Landusky Mine KW - surface mining KW - igneous rocks KW - pollution KW - effects KW - Swift Gulch KW - Montana KW - intrusions KW - plutonic rocks KW - Zortman Mine KW - open-pit mining KW - syenites KW - 22:Environmental geology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/877847104?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Abstracts+with+Programs+-+Geological+Society+of+America&rft.atitle=Zortman-Landusky%3B+challenges+in+a+decade+of+closure&rft.au=Williams%2C+R+David%3BShaw%2C+Shannon%3BJepson%2C+Wayne+E%3BGammons%2C+Christopher+H%3BKill+Eagle%2C+John+L%3BAnonymous&rft.aulast=Williams&rft.aufirst=R&rft.date=2009-10-01&rft.volume=41&rft.issue=7&rft.spage=558&rft.isbn=&rft.btitle=&rft.title=Abstracts+with+Programs+-+Geological+Society+of+America&rft.issn=00167592&rft_id=info:doi/ LA - English DB - GeoRef N1 - Conference title - Geological Society of America, 2009 annual meeting N1 - Copyright - GeoRef, Copyright 2012, American Geosciences Institute.

This abandonment has been observed in the form of decreased boat clearance at both upstream and downstream side channel connections with the main channel. This study evaluates geomorphic changes along the lower Bighorn River associated with the construction of Yellowtail Dam in 1966 and investigates the mechanisms leading to the abandonment of side channels. Analysis of cross section data from the long-term gaging station in the study reach and from seven sets of rectified historical aerial photography from 1939 to 2006 reveals that vertical incision and lateral migration have been relatively minimal and do not appear to be the cause of side channel loss. Mapping of the active channel, side channels, vegetated islands, unvegetated gravel bars, and overflow channels show that the active channel area has remained similar while the number of vegetated islands decreased dramatically in response to the abandonment of overflow channels following the construction of Yellowtail Dam. The sharp decrease in vegetated islands was followed by a slow increase in their areal coverage from 1970 to 2006. The areal extent of unvegetated gravel bars gradually decreased from 1939 to 2006, and documents the effects of decreased sediment supply and peak discharges in conjunction with vegetation encroachment in response to Yellowtail Dam and potentially the earlier construction of Boysen Dam in 1952. This study proposes that side channels are progressively abandoned by vertical accretion of fine sediment in side channel entrances and mouths; without the scouring effects of larger peak discharges, fine sediment accumulations block lower discharges from entering the side channels at their upstream ends. This work corroborates the results of previous studies on the Bighorn River (e.g., Martin, 1974) and documents fine sediment accumulation and fluvial adjustments through 2006 along the Bighorn River.

Traditionally, the use of species as the unit of comparison has restricted this technique to Holocene fossil assemblages. More recently, higher taxa such as genera and families have been shown to provide comparable results to species-level analyses, and have extended the reach of taxonomic calibration to much older time periods. Unfortunately, in all cases, the use of taxonomic ranks introduces bias due to the treatment of closely-related taxa as independent observations and discards information at present at deeper evolutionary nodes. In this study, we explore the use of community phylogenetic methods for paleoclimate reconstruction by using a large database of modern forest inventories to estimate paleotemperature for several fossil assemblages, including the late Eocene Florissant fossil flora.

The site became world famous as paleontologists Leo Lesquereux, Samuel Scudder, and E. D. Cope described hundreds of new species of fossil plants, insects, spiders, and vertebrates. The extent of these contributions might not have been possible without the assistance of an early homesteader, Mrs. Charlotte Hill, who lived at the site and collected many of the first specimens. In 1880, a Colorado newspaper described that Mrs. Hill "has turned naturalist, and has displayed at her home an elegant array of geological specimens." Some of the earliest paleontological expeditions to the site sought to make contact with Mrs. Hill, who provided them with hundreds of fossil specimens. For example, a large portion of the type specimens of fossil plants described by Lesquereux were collected by Mrs. Hill. Lesquereux described her in an 1883 monograph as "the proprietress of the land where are exposed the banks containing the richest fossiliferous shale," and he named three new species in her honor including a fossil rose, Rosa hilliae. One of the most remarkable fossil butterflies ever found was the specimen of Prodryas persephone collected by Charlotte Hill and described by Samuel Scudder, and it remains a hallmark in the collection at Harvard University. Evidence in support of her contributions has come from the development of a new database of published fossil specimens, and from investigations of early newspaper reports, scientific publications, expedition journals, and museum records. As a young woman homesteader, Charlotte Hill exemplified an unusual passion for understanding and promoting the fossil resources on the land that was her home, and she played a significant role in unveiling Florissant's place in world fame.

The magnitude of coal fire emissions is poorly constrained and as such, coal-fires are generally not included as a source category in estimating global atmospheric greenhouse and toxic gas budgets. In an effort to begin to quantify the magnitude of coal-fire emissions, a ground-based approach was developed to calculate fluxes of CO (sub 2) from several coal fires in the U.S.. This approach combines CO (sub 2) emissions from vent fluxes and diffuse soil fluxes. Vent fluxes are calculated from CO (sub 2) concentrations, vent flow, and vent area measurements. Soil flux measurements are taken in a gridded pattern circumscribing the fire and interpolated using geostatistical methods. This combination of techniques was applied to active coal fires along the Tongue River in the Powder River basin, Wyoming, including the Welch Ranch fire and the Hotchkiss fire. Comparison of calculated vent emissions with preliminary estimates of diffuse CO (sub 2) soil flux indicates diffuse fluxes are similar to or less than vent emissions. For the Welch Ranch fire, vent emissions are 6.8 + or - 2.4 Mg CO (sub 2) d (super -1) . For the Hotchkiss fire, vent emissions are 0.65 + or - 0.05 Mg CO (sub 2) d (super -1) . For a third Powder River basin fire, the Ankney Fire, access and safety concerns limited measurement coverage so that a partial vent flux of 1.6 + or - 0.3 Mg CO (sub 2) d (super -1) was determined. Vent measurements of CO, CH (sub 4) , H (sub 2) S and Hg allow calculation of vent emissions for these constituents from each fire. For the Welch Ranch fire, these values range from 270 + or - 47 mg d (super -1) for Hg to 18 + or - 6.3 kg d (super -1) for CO. Ground-based measurements for the three Powder River basin coal fires are being compared to contemporaneous airborne tropospheric CO (sub 2) measurements and thermal infrared imaging in order to integrate ground-based and airborne determinations.

Production requires the removal and management of large quantities of water from coalbeds that are commonly used aquifers in this region. The Powder River Basin is a semi-arid region with an agricultural-based economy that is dependent on the availability of groundwater. Due to this conflict, a variety of conceptual and quantitative models have been developed to evaluate the potential impacts to water availability (e.g. Wheaton and Metesh, 2002 and Myers, 2009). The differences in these models make it clear that long-term monitoring of actual impacts is required to determine which modeling assumptions are valid and to verify the magnitude of actual impacts as well as the lack of impacts. In Montana, a regional CBM groundwater monitoring program is operated that includes inventories of groundwater resources and regular monitoring at 234 wells, 15 springs, and 2 streams. Data are also collected from CBM wells, domestic wells and livestock wells. Monitored units include coalbeds, adjacent sandstone units, and alluvium (Meredith et al., 2009). This monitoring shows that after 10 years of CBM production, the 20 foot drawdown contour extends roughly 1 to 1.5 miles outside the production areas; that major faults tend to act as barriers to ground-water flow; and that vertical migration of drawdown tends to be limited by shale layers. The hydrogeologic assessment in the BLM's Montana CBM EIS was based in part on computer modeling. It was projected that after 10 years of development the 20 foot drawdown contour would reach approximately 2 miles from the edge of development. It was also anticipated that faults would act as barriers to drawdown, and that that impacts to overlying or underlying aquifers would be minor due to the confined nature of the coals. As such, observed impacts appear to be in line with, or somewhat less than, the projections contained in the Montana CBM EIS. Other models which predict greater impacts do not appear to be supported by the monitoring data.

We have characterized 4 potential variscite source localities in northern Utah: Fairfield and Amatrice Hill in Tooele County, and Lucin and Snowville in Box Elder County. Microprobe analysis reveals that Fe and Cr abundances are particularly good discriminators. A cross-plot of these elements separates the 4 sources with effectively no overlap, making it possible to clearly tie artifacts to source locations and ultimately infer trading patterns. Minimal damage to small artifacts is accomplished by the use of 1" diameter plastic disc sample holders. Artifacts are placed into a hole drilled into the disc and then embedded in epoxy for later recovery by dissolution in methylene chloride. Hole diameters and artifact placements are chosen so that minimal grinding and polishing of the artifact is required. 20 nA and 20 mu m beams were use to minimize readily apparent beam damage. Due to a lack of variscite microprobe standards, we calibrated Al & P on Lucin variscite, Si & Ca on wollastonite, Na on Jadeite, Cr on chromite, Fe on garnet, As on synthetic GaAs, and Co and V on metal alloys. This may produce systematic differences in "true" versus "apparent" abundances, but excellent reproducibility and source discrimination is achieved.

The National Park Service, working in conjunction with the USDA-Natural Resources Conservation Service (NRCS) in the ongoing mapping of our Parks is taking a closer look at the genesis, morphology, and distribution of soil organic carbon (SOC) in the soils of our parks to educate the public about the important role soils play in storing carbon and to help park staff better manage their lands in terms of a park's carbon footprint. Using an interpretation generator within the National Soil Information System (NASIS) platform it is possible to export classes of soil organic carbon (SOC kg/m2 to either 1 meter or two meters) to create maps and tables that clearly illustrate the distribution and relative amounts of organic carbon stored in soils. Carbon maps can help prioritize restoration areas and can also be used to help select areas for detailed soil carbon research. Comparative levels of SOC from different park units will be displayed and discussed in relation to their soil climate regimes.

Coalbed methane (CBM) production, which began in this area in April 1999, requires the removal and management of large quantities of water from coalbeds. These same coalbeds are commonly used as aquifers in this region, providing a reliable source of domestic and livestock water in these rural areas. In Montana, during 2008, 772 CBM wells discharged at an average rate of 4.0 gallons per minute. Due to the importance of groundwater, and the need to understand the actual impacts to aquifers, a regional monitoring network was established. The Montana regional CBM groundwater monitoring program has been in operation for 10 years, but was built upon an existing program that has been continually active in the area since 1970. The program includes regular monitoring at 234 wells, 15 springs, and 2 streams. Monitored units include coalbeds, adjacent sandstone units, and alluvium (Meredith et al., 2009). This program provides documentation of the potentiometric surfaces and water level changes and will continue to be active throughout the duration of CBM production and post-production groundwater recovery. Groundwater levels have been drawn down by over 200 feet in the producing coalbeds. The actual amount of drawdown in some wells cannot be measured due to safety concerns as a result of methane release from monitoring wells. After 10 years of CBM production, the 20 foot drawdown contour extends roughly 1 to 1.5 miles outside the production areas. Major faults tend to act as barriers to groundwater flow and drawdown does not migrate across fault planes where measured in monitoring wells. However, in cases where faults are not offset by at least 10 feet more than the thickness of the coal, they are less likely to act as a barrier. Vertical migration of drawdown tends to be limited by shale layers; however in some cases minor changes in overburden head have been observed.

The geology of the area includes the Lower Cretaceous Edwards and Trinity limestones, including Glen Rose (Trinity), and Maxon and Del Carmen Formations (Edwards). Structurally, the area is located west of the Devil's River uplift, southeast of the Marathon Basin, and east of the Laramide structures in the Persimmon Gap area of Big Bend National Park. The area is being studied to evaluate the hydrodynamics of numerous springs that emerge from trans-boundary aquifers, the Edwards-Trinity Plateau aquifer that extends from eastern Brewster County north to Midland and east to the Texas Hill Country and two aquifers in the Mexican State of Coahuila. The structural features of the area include several large scale NW trending folds. The Bullis fold is a broad anticline with a fold axis bearing of 318 degrees. The fold is broken approximately along the axial plane by a reverse fault. In the same area minor folds exist perpendicular to this structure. The Lower Canyons area is pervasively fractured by a system of joints trending roughly NNW. We have divided these joints into three groups based upon their magnitude of fracture and their spatial repeat distance. These include a "fine" set of joints with a repeat interval of 20 meters and an average trend between 334 and 355 degrees, a "medium" set with a spatial repeat interval of 130 meters and an average trend of 310 to 320 degrees and a "coarse" set with a spatial repeat pattern of 2.49 km and a trend of 310 to 320 degrees. Additionally a thrust fault has been mapped on the Mexican side of the river downstream from the Bullis Fold. The Rio Grande in the Lower Canyons follows a structurally controlled "rectangular" pattern. The relatively linear reaches have trends of approximately 285 degrees and 15 degrees (90 degree angular difference). The axial trends of the Bullis and other smaller folds in the area are consistent with a Laramide tectonic association, even though this area is east of the major Laramide related structures. The structures downstream from the Bullis fold hint at a transpressional origin with joint trends indicating right lateral stress. This is consistent with structures to the west in the Persimmon gap area.

To provide better baseline data regarding these fossils, paleontological data-mining efforts have been initiated in dozens of NPS areas in conjunction with NPS Inventory and Monitoring (I&M) Networks. Paleontological resource inventories have been completed for over four-fifths of these networks. Such an inventory was recently undertaken for NPS areas in the Southern Colorado Plateau Network. The Southern Colorado Plateau Network consists of nineteen park areas throughout Arizona, Colorado, New Mexico, and Utah. This inventory was the first comprehensive literature search and summary of recent and historical paleontological research for the parks of the network. Eighteen of the network's parks preserve fossil resources, including some of the best-known occurrences in the NPS at parks like Canyon de Chelly NM, Chaco Canyon NHP, Glen Canyon NRA, Grand Canyon NP, Mesa Verde NP, and Petrified Forest NP. Taken together, the parks and monuments of the network preserve a fossil record extending from the Mesoproterozoic to the present. Plants, invertebrates, vertebrates, and trace fossils are all well-represented. Fossils associated with cultural resources are also common in most of the network parks, such as tools made of petrified wood. The richness of the fossil record has promoted educational and interpretive efforts, and led to management challenges related to fossil theft and vandalism. Highlights include some of the oldest fossils of the American Southwest, Permian trace fossils and plants, Triassic petrified forests and their inhabitants, Early Jurassic tracks, marine invertebrates and vertebrates from the Middle Cretaceous, and extensive collections of fossils useful for Quaternary paleoecological studies, such as pollen, packrat middens, and mammal dung. The network units are also sites of both historically important paleontological research and ongoing work of note. This inventory aims to stimulate future research, education, interpretation, and proper resource management of these paleontological resources.

A Geopark may consist of a single site, but often includes multiple publically accessible sites linked by one or more geologic themes such as paleontology, glaciation, or volcanism, or people's uses of the land that are influenced by geology such as mining or winemaking. Geoparks assist local economies, particularly through geotourism, educate the public about geological heritage and the links between geology, ecosystems, and cultural and economic activities, and encourage increased geological knowledge through research. The Geoparks network is assisted by UNESCO, but is not a formal U.N. program. The U.S. is not yet a member. Many geologically significant areas in the U.S. are managed primarily by multiple-use agencies such as the Bureau of Land Management and U.S. Forest Service. Despite their geologic significance, such areas are generally not eligible for World Heritage designation because economic activities are allowed, even if they do not materially affect geologic resources. These areas, including some of the world's most impressive geologic sites, could receive international recognition through the Geoparks program and substantially enhance public appreciation for geology. The National Park Service is working with the Geological Society of America to assess support for U.S. participation in the Geoparks network. Input on draft U.S. Geoparks program guidelines will be solicited from land managers and the geologic community. A multiagency proposal to join the international Geoparks program will be prepared for approval by the U.S. National Commission on UNESCO and the State Department. If approved, it will be submitted to UNESCO for ratification at the next international Geoparks Congress in April 2010. If the U.S. joins the Geoparks network, 2 Geoparks will be nominated and forwarded to UNESCO every other year. Local support from land managers and the public is required for a Geopark nomination; sites will not be pre-selected from Washington. Participation by the geologic community is essential for a U.S. Geoparks program to succeed. Geologists will be needed to help organize local support for Geopark designation, help prepare site nominations, and serve on the U.S. Geoparks Committee.

We found that radio-tagged juvenile steelhead approached and entered two spillbays (one lighted, one unlighted) in equal proportions. However, the presence of strobe lights was associated with decreased spillbay residence time of juvenile steelhead and increased passage through induction slots (secondary turbine intakes located upstream of the ogee on the spillway). Mean residence time of tagged fish inside the lighted spillbay was 14 min compared to 62 min inside the unlighted spillbay. Radio-tagged steelhead passed through induction slots at a higher proportion in the lighted spillbay (55%) than in the unlighted spillbay (26%). Recent studies have suggested that strobe lights can induce torpor in juvenile salmonids. We believe that strobe light exposure affected fish in our study at a location where they were susceptible to high flows thereby reducing mean residence time and increasing the proportion of tagged fish entering induction slots in the lighted spillbay. Our results suggest that factors such as deployment location, exposure, and flow are important variables that should be considered when evaluating strobe lights as a potential fish-deterring management tool.

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, and the influence that the springs have on water quality and quantity in the Rio Grande. On the Texas side, the Cretaceous-hosted Edwards-Trinity Plateau aquifer is extensive. On the southern side, two aquifers in the Mexican State of Coahuila have been delineated (Cerro Colorado-La Partida and Serrania Del Burro). International Boundary and Water Commission (IBWC) gage data indicate that base flows progressively increases by as much as 60% due to spring inflow in the LC. Independent discharge measurements made above and below several spring groups indicate that ground water from Cretaceous aquifers account for most of this increase. Ground water input is also responsible for dilution of total dissolved solids (TDS) in river waters. Water quality for the river reach above BBNP fails to meet EPA standards for TDS. The Rio Grande segment that contains the LC springs meets standards because TDS diminishes downstream as lower TDS spring inputs contribute to river discharge and to the dilution of high TDS water. Specific conductivity (SC) for the springs averages 734 uS/cm whereas the river samples adjacent to the springs average 2348 uS/cm. The SC in the river declines from a maximum of 2510 uS/cm at river mile 716 to 2150 uS/cm at river mile 761. Seven spring samples collected in March of 2009 averaged 461 mg/L TDS (706 uS/cm). 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 generic "no dominant ion" type of water and a second set with an average of 282 mg/L TDS that plots as a calcium-bicarbonate type water. Oxygen and hydrogen isotope analyses indicate that the springs cluster in two groups on a local meteoric water line (LMW) that is shifted to lower d (super 18) O by 0.5 ppm. Differences between, and variability within, the clusters may reflect differences in recharge elevation and water-rock reaction effects. River waters show evaporative enrichment and are distinctly different from spring waters.

For the spring of 2009, a geology course was offered involving a one-week outing in a remote location in Denali, aimed at focusing on gold mining claim evaluations using systematic gold panning, shallow seismic investigations, surface geology evaluations, GPS oriented claim staking, and final property reserve calculations. Expeditionary Learning attempts to bring experts into the classroom, takes students into the field, and engages students in real world learning experiences. The idea was popularized by the Outward Bound Organization, where outdoor field experiences, developing teamwork, courage, craftsmanship, perseverance, and compassion, are used to create powerful learning experiences and foster academics and personal growth. The course took place in the Kantishna mining district of Denali National Park and Preserve, and involved eleven student participants (and three instructors) spending one day of in-stream pan sampling of placer claims, a second day of seismic evaluation of gravel depths and gold recovery-reserve calculations, and a third day completing a GPS survey of 3 adjacent lode claim boundaries. Students then assembled final reports and slideshows demonstrating the reserve gold values and methodologies to obtain the data. The participants learned the particulars of placer gold origin and deposition, excavation and panning techniques, the mineral components of black sand concentrates and fine gold reduction, subsurface layer character and acoustic responses, three-dimensional mineral reserve modeling, and GPS survey techniques, including GPS data overlay on map and satellite images. Success was partially demonstrated by the in-depth reports, slideshows, movies and posters presented to parents and the public on the final day of the course. But the greatest demonstration of success was watching teenagers panning into the late hours of the "midnight sun" for gold, and for the magic, mesmerizing mineral, magnetite, which was infinitely more abundant than the gold.

Innovative collaboration with, and volunteerism by researchers has served the NPS well over the years to provide needed projects and research. This paper describes a proposed program that offers a first-hand introduction to research needs of parks administered by the NPS for a diverse group of researchers, in hopes of initiating needed work that would otherwise not be undertaken. The program involves the NPS and the Honors College of the University of Arkansas, although the underlying rationale of collaboration with the NPS would be equally appropriate for most universities, government agencies, and other research centers. At Arkansas, students in the Honors College are required to write a Senior Honors Thesis, and thanks to generous funding by the Walton Family Trust, reasonable expenses related to field research are covered. Theses typically address a range of research problems from theoretical to applied, they typically require extensive field work, and they encompass disciplines ranging across park needs from geology, biology, ecology, mapping, and environmental, to social and political science, to policy and management. Utilizing the format of an 8-day field trip during spring break, the students are exposed to parks, monuments, historical sites, battlefields, and national rivers and seashores by scientists of the NPS. Meaningful, relevant problems at each site are presented in detail, and important contacts between each student and key NPS scientists are initiated. Research areas of focus are selected based on the proximity of NPS facilities (Four-Corners area; Virginia-Washington D.C.; Bay area-Sierras) so that transportation time is minimized and time spent understanding park needs is optimized. Prior to the field trip, colloquia and on-campus endeavors bring the students up-to-speed on problems, and at the conclusion of the class, research proposals are submitted. We share specific examples and case studies to document the sophistication of the research, and point to potential research and benefits that we hope will accrue.

The first American coprolite was described in 1830 from the Upper Cretaceous of New Jersey and it probably represents Liassocopros. The oldest significant coprofaunas are from three paleoenvironments in the upper Paleozoic: (1) black shales (e.g., Pennsylvanian of Illinois); (2) lagoonal shales (e.g., Pennsylvanian of New Mexico); and (3) redbeds (e.g., Lower Permian of Texas and New Mexico). The majority of these coprolites are interpreted as derived from fish. Triassic redbeds of the Southwest and lacustrine shales of the Newark Supergroup contain a significant number of vertebrate coprolites. Redbed coprolites increase in abundance and diversity into the Upper Triassic. The majority of coprolites continue to pertain to fish, but terrestrial reptile coprolites (e.g., Dicynodontocopros) become more common in the Upper Triassic. Jurassic and Cretaceous nonmarine strata yield tetrapod coprolites, including theropod and crocodylian specimens, but they are relatively uncommon. Coprolites are locally common in Paleogene fluvial strata of the Western United States and abundant in the lacustrine units of the Eocene Green River Formation of Utah, Wyoming and Colorado. The upper Eocene/lower Oligocene White River Group, notably in South Dakota, contains large coproassemblages derived from terrestrial mammals. Pleistocene caves of Arizona, Utah and Nevada and New Mexico contain large deposits of the dung of mammals, including ground sloth, mammoth, mountain goat and Bighorn sheep. Human coprolites are known principally from caves in the desert Southwest and West as well as the southeastern United States. The coprolite record in the United States has six acme zones: (1) Pennsylvanian (2) Early Permian; (3) Late Triassic; (4) early Eocene; (5) late Eocene-early Oligocene; and (6) Pleistocene. The application of binomial nomenclature has demonstrated the utility of coprolites for biostratigraphy and biochronology of the Permian and Triassic.

Approximately 12 National Parks and Monuments contain vertebrate coprolites. The three most important ichnoassemblages are at Petrified Forest National Park (PEFO), Badlands National Park (BADL) and Grand Canyon National Park (GRCA). These ichnoassemblages represent three of the acme zones for vertebrate coprolites in North America: Late Triassic at PEFO (Chinle Group), Eocene-Oligocene at BADL (White River Group) and Pleistocene at GRCA (cave deposits) and have been central to recent work on paleoecology and biochronology. The Blue Mesa and Painted Desert members of the Petrified Forest Formation (Chinle Group) at PEFO yield abundant vertebrate coprolites. The superposition of ichnoassemblages at PEFO demonstrates the biostratigraphic and biochronologic significance of Late Triassic coprolites, such as Dicynodontocopros and Heteropolacopros, which are restricted to the upper Carnian (Adamanian) portion of the section. The White River coprolites of BADL and surrounding areas are the most studied Cenozoic vertebrate coprolites. Some contain casts and molds of hair and occasionally microvertebrate bones. These coprolites have been the focus of significant studies of Oligocene bone processing by predators/scavengers. The numerous caves developed in Paleozoic limestones at GRCA yield an abundance of Pleistocene vertebrate coprolites representing at least six mammals and raptors. The largest dung deposits represent the Shasta Ground Sloth and have been at the core of several paleoecological studies (diet, DNA, parasitology, trace elements). The largest dung blanket at Rampart Cave was severely impacted by a fire in 1976. Coproassemblages from NPS units represent a significant paleontological resource that has been pivotal to recent advances in the study of coprolites. Resource management needs to be sensitive to the preservation and interpretation of vertebrate coprolites.

We interpret the sheet sandstone as the result of an avulsion flood event which swept over the floodplain, leaving up to 1 meter of medium coarse sand. Most primary sedimentary structures have been destroyed by bioturbation. Upper parts of the sandstone preserve tracks and trackways of Subhyracodon, Poebrotherium, Mesohippus, entelodonts, oreodonts, birds and invertebrates. The period during which tracks were actively being preserved was likely short as burial would have taken place rapidly. The Toadstool trackways thus preserve a snapshot of life on an active floodplain. The various track morphologies combined with textural differences within the sheet sandstone offers a rich source of detailed information about the geologic environment in which they were formed. Experimental photogrammetric documentation of the trackways is proposed as a technique allowing their detailed study by multiple researchers while effectively preserving fragile ichnological information whose primary sources are being destroyed by weathering, erosion, and vandalism.

The geology of the Powder River basin in Wyoming and Montana provides an unusually good opportunity for dating landforms that reflect stream incision: numerous coal seams in the Paleocene Fort Union Formation within the basin have caught fire during late Cenozoic incision, with lowering of the groundwater table and exposure of the coal to dry, oxygen-rich conditions. We use zircon (U-Th)/He ages of the clinker to constrain erosion, with the assumption that coal must be near Earth's surface to burn. The precision of ages (generally 80 sites with many replicates) allow statistical analyses of the relationship between landscape evolution and climate in the basin since 1 Ma. The probability density function of the ages for the entire basin shows two temporal patterns: 1) a bias toward younger ages because of erosion of older clinker, and 2) episodic occurrence of coal fires corresponding with times of high eccentricity in Earth's orbit and low global ice volume. A spectral analysis of the probability density function shows peaks in spectral density at approximately 100 kyr and approximately 250 kyr periodicities. Ages farther than 50-km from the Bighorn Mountain front show stronger statistical correlations with climate records than ages close to the mountain front, suggesting that glaciers in the stream headwaters do not provide the primary climatic control on downstream incision rates. This is contrary to previous studies that have tied the formation of strath terraces in Rocky Mountain basins to cycles of upstream glacial erosion.

During initial fire fighting efforts, large amounts of fire retardant, chemicals known to be harmful to aquatic invertebrates, were dumped on the upper reaches of these surface drainages. The drainages downstream of the retardant drops is home to approximately half of the known habitat for the endemic Big Spring Isopod (Bowmanulus sequoiae). To determine the effect of these fire suppression activities on the aquatic karst ecosystems, water chemistry data was collected both during and after the fire from karst springs and surface creeks. Additionally, biological inventories of karst springs and subsurface streams were conducted prior to and after the winter rains. These inventories show no statistical change in isopod populations within the basin, suggesting minimal negative effects of the retardant chemicals. Water chemistry data also supported this finding with no statistical change in cation concentrations or nutrient levels associated with fire retardant. This suggests a series of potential buffers: (1) the karst groundwater systems provide buffering of the negative effects of fire retardant on aquatic species, (2) the combination of distance of the fire retardant drops from streams and vegetation uptake of nutrients reduced its effect on the aquatic system, or (3) large rainfall events through the winter diluted the concentration of these chemicals enough to negate the effects.

Photographs of sand- to boulder-sized sediment along the Elwha River delta beach were taken from approximately 1.2 m above the ground surface, and detailed grain size measurements were made from 32 of these sites for calibration and validation. Digital photographs were found to provide accurate estimates of the long and intermediate axes of the surface sediment (r2 > 0.98), but poor estimates of the short axes (r2 = 0.68), suggesting that these short axes were naturally oriented in the vertical dimension. The autocorrelation method was successfully applied resulting in total irreducible error of 14% over a range of mean grain sizes of 1 to 200 mm. Compared with reported edge and object-detection results, it is noted that the autocorrelation method presented here has lower error and can be applied to a much broader range of mean grain sizes without altering the physical set-up of the camera (200-fold versus 6-fold). The approach is considerably less sensitive to lighting conditions than object-detection methods, although autocorrelation estimates do improve when measures are taken to shade sediments from direct sunlight. The effects of wet and dry conditions are also evaluated and discussed. The technique provides an estimate of grain size sorting from the easily calculated autocorrelation standard error, which is correlated with the graphical standard deviation at an r2 of 0.69. The technique is transferable to other sites when calibrated with linear corrections based on photo-based measurements, as shown by excellent grain-size analysis results (r2 = 0.97, irreducible error = 16%) from samples from the mixed grain size beaches of Kachemak Bay, Alaska. Thus, a method has been developed to measure mean grain size and sorting properties of coarse sediments.

In OPLA Title VI, Subtitle D on Paleontological Resources Preservation, the Secretaries of the Interior and Agriculture are directed to "manage and protect paleontological resources on Federal land using scientific principles and expertise." For the individual Federal land management agencies, the effects of PRPA will generally be minimal because PRPA affirms many of the existing policies currently employed by these agencies. Paleontological permitting will now be authorized under PRPA. Also, PRPA will provide law enforcement with new tools and authorities for prosecuting fossil theft and paleontological resources damage cases. Additionally, on National Park Service (NPS) lands, management and preservation of resources will not drastically change, except regarding law enforcement issues. The most significant contribution of PRPA is its provisions pertaining to law enforcement and protection of paleontological resources. These new provisions include the authority for criminal and civil penalties that are targeted at large scale fossil theft, interstate commerce, and repeat offenders. PRPA also requires that the Secretaries of the Interior and Agriculture allow casual collecting of a reasonable amount of common invertebrate and plant paleontological resources for non-commercial personal use without a permit on certain federal lands. Under PRPA, the Federal land agencies will also establish programs to increase public awareness and will develop plans for inventorying, monitoring, and deriving the scientific and educational use of paleontological resources.

This work is supported by the USGS National Cooperative Geologic Mapping Program (FEDMAP, STATEMAP, EDMAP), the National Science Foundation, the National Park Service, two State Geological Surveys, and three university geology/river studies departments. Central to this work is geologic mapping of the floodplain to delineate and test depositional facies models, and to map past positions of a very dynamic river system in postglacial time with scores of 4-7 m deep auger holes and age control from optically stimulated luminescence dating. Postglacial deposits of the valley floor are bounded on the north and underlain by late Wisconsin glacial and glaciofluvial deposits of the James River lobe of the Laurentide ice sheet that advanced to this part of the MNRR area across a partly forested parkland that has yielded many (super 14) C ages on wood of approximately 12,500 (super 14) C years BP. The re-advance was followed closely by calcite precipitation from groundwater, as constrained by mass spectrometric U-series, Sr, and stable isotope data. New mapping results from the Wynot 7.5-minute quadrangle in Nebraska contrast markedly to the James lobe terrain in South Dakota; the mapping shows that uplands south of the MNRR include a discontinuous to thick loess mantle over a complex of pre-Illinoian till, gravel, sand, and silt with little spatial correspondence to the younger superimposed southeast-oriented valley network. There is particular interest in understanding the relation of buried Pleistocene glaciofluvial gravel to the modern river channel; these gravel deposits may be a primary control on groundwater/surface water interactions as well as a source of gravel-cobble substrate needed for spawning of endangered sturgeon. Our geologic work is designed to provide data for adaptive management of this segment of the Missouri River, including information to help guide restoration of habitats for native fishes and shorebirds. A NPS Geologic Resources Division scoping meeting in August 2008 facilitated the communication and discussion of these results and further honed the orientation and needs for geologic mapping.

They discharge water from the base of the ice in large, episodic events. Sediment removed from at least the tunnel floor, creates the erosional form we observe, and is deposited in front of the glacial margin where conditions are suitable for it to accumulate. The classic landform assemblage includes a broad channel that rises to the ice sheet margin (moraine) that in some cases contains an esker, both of which lead to a break in the moraine, where deposition begins (Clayton et al., 1999). A network of anastomosing tunnels preserved in the sandstone floor of the eastern Lake Superior Basin (Patterson et al., 2003; Regis et al., 2003; Derouin, 2008) average 5 km in width and reach different depths of incision. Some are over 200 m deep and over 100 km long. Directly south of the Lake Superior tunnel channels, the eastern Upper Peninsula of Michigan, a narrow land mass between Great Lakes basins, is dominated by large fan deposits and a moraine-complex comprised of overlapping fan heads (Blewett and Winters, 1987; Derouin, 2008). The goal of this study was to compare the amount of material (in metric tons) missing from the channels to that deposited in the fans using GIS analysis of the digital elevation models based on SRTM elevation data for the surface, NOAA data for the lake floor and interpolation of available well logs for the subsurface. The mass of the fans was calculated assuming that all sand deposited above the bedrock surface originated from tunnel discharge. The mass of tunnel channels were calculated assuming an initially flat lake floor, and subtracting the material from the channels incised into the sandstone. The fans contain over 7 X 10 (super 10) Metric tons of mainly sand, while the tunnel channel incision through sandstone removed over 1 X 10 (super 12) Metric tons of material from the bedrock basin. This suggests that two orders of magnitude of sediment was transported away from the Upper Peninsula, potentially deposited in Lake Michigan, Lake Huron, and the Lower Peninsula of Michigan. We suggest potential areas of sediment accumulation include the sand on the northwest shore of the Lower Peninsula of Michigan (e.g. Sleeping Bear Dunes) and partially-filled tunnel channels in on the Lake Michigan floor.

However, monitoring rock-fall activity has previously proved challenging due to a lack of high-resolution "basemap" imagery of the Valley walls. The Yosemite Extreme Panoramic Imaging Project, a partnership between the National Park Service and xRez Studio, has created an unprecedented image of Yosemite Valley's walls by utilizing gigapixel panoramic photography, LiDAR-based digital terrain modeling, and three-dimensional computer rendering. Photographic capture was accomplished by 20 separate teams shooting from key overlapping locations throughout Yosemite Valley. Photographs were taken simultaneously in order to ensure uniform lighting, with each team taking over 500 overlapping shots from each vantage point. Each team's photographs were then assembled into 20 gigapixel panoramas. In addition, all 20 gigapixel panoramas were projected onto a 1 meter resolution digital terrain model in three-dimensional rendering software, unifying Yosemite Valley's walls into a vertical orthographic view. The resulting image reveals the geologic complexity of Yosemite Valley in high resolution and represents one of the world's largest photographic captures of a single area. Several substantial rock falls have occurred since image capture, including large rock falls from Glacier Point in October 2008 and from near Half Dome in March 2009. Repeat photography of these areas clearly delineates the rock fall source areas, aids in volumes estimates, and informs the failure dynamics. In addition, smaller rock falls not previously documented have been discovered by comparing imagery. Thus, the panoramic gigapixel imagery has already proven to be a valuable tool for monitoring and quantifying rockfall in Yosemite Valley. It also sets a new benchmark for the quality of information a photographic image can provide for earth science study.

These fossils represent one of the best-preserved, Late Cretaceous polar continental ecosystems in the world. Since the first footprint discovery in 2005, thousands of trace fossils of fish, pterosaurs, theropods, hadrosaurs, aves, and terrestrial and aquatic invertebrates have been found in the lower Cantwell Formation. Site occurrences range from large bedding planes with hundreds of tracks, to single footprints with skin impressions, coprolites, and other isolated traces, found at accessible and remote locations. This newly discovered resource represents an enormous challenge to DENA to provide for research, public education, and protection from both natural and human impacts. Recognizing this vast new paleontological resource, the NPS is developing a Paleontology Management Plan (PMP) to provide the appropriate guidance in the near future to understand and protect this resource. Plant and invertebrate fossils are long known from Paleozoic and Mesozoic rocks in DENA. An inventory of the paleontological literature in 1998 recorded ten phyla of marine macroinvertebrates, five kinds of microfossils, a variety of plants, and some trace fossils, representing over 1,000 records and some 275 localities. The recent discovery of dinosaur trace fossils has increased the number of localities by at least 100 or more. Localities range from entire mountain slope trackways to individual blocks. The PMP includes legal authorities, background geology and paleontology, paleo-inventory and monitoring status, resource (impact) concerns, relationships with other park divisions, permit and collections procedures, and educational and access conditions. The plan is intended to provide guidance to management regarding inventory and research, protection and public access, educational opportunities, and support needs. A principal constituent of the plan is the suggested development of Paleo Locations of Management Concern (PLMC), which are area designations of unique or concentrated specimens, or areas of environmental or human risk, that may need additional management attention.

AN - 67692740; 19831066 AB - The ridge and slough landscape of the Florida Everglades consists of a mosaic of linear sawgrass ridges separated by deeper-water sloughs with tree islands interspersed throughout the landscape. We used pollen assemblages from transects of sediment cores spanning sawgrass ridges, sloughs, and ridge-slough transition zones to determine the timing of ridge and slough formation and to evaluate the response of components of the ridge and slough landscape to climate variability and 20th-century water management. These pollen data indicate that sawgrass ridges and sloughs have been vegetationally distinct from one another since initiation of the Everglades wetland in mid-Holocene time. Although the position and community composition of sloughs have remained relatively stable throughout their history, modern sawgrass ridges formed on sites that originally were occupied by marshes. Ridge formation and maturation were initiated during intervals of drier climate (the Medieval Warm Period and the Little Ice Age) when the mean position of the Intertropical Convergence Zone shifted southward. During these drier intervals, marsh taxa were more common in sloughs, but they quickly receded when precipitation increased. Comparison with regional climate records suggests that slough vegetation is strongly influenced by North Atlantic Oscillation variability, even under 20th-century water management practices.

AN - 67657224; 18946720 AB - Semipermeable membrane devices (SPMDs) were deployed in streams along a gradient of urban land-use intensity in and around six metropolitan areas: Atlanta, Georgia; Raleigh-Durham, North Carolina; and Denver-Fort Collins, Colorado, in 2003; and Dallas-Fort Worth, Texas; Milwaukee-Green Bay, Wisconsin; and Portland, Oregon, in 2004 to examine relations between percent urban land cover in watersheds and the occurrence, concentrations, and potential toxicity of hydrophobic compounds. Of the 142 endpoints measured in SPMD dialysates, 30 were significantly (alpha = 0.05) related to the percent of urban land cover in the watersheds in at least one metropolitan area. These 30 endpoints included the aggregated measures of the total number of compounds detected and relative toxicity (Microtox(R) and P450RGS assays), in addition to the concentrations of 27 individual hydrophobic compounds. The number of compounds detected, P450RGS assay values, and the concentrations of pyrogenic polycyclic aromatic hydrocarbons (PAHs) were significantly related to percent urban land cover in all six metropolitan areas. Pentachloroanisole, the most frequently detected compound, was significantly related to urban land cover in all metropolitan areas except Dallas-Fort Worth. Petrogenic PAHs and dibenzofurans were positively related to percent urban land cover in Atlanta, Raleigh-Durham, Denver, and Milwaukee-Green Bay. Results for other endpoints were much more variable. The number of endpoints significantly related to urban land cover ranged from 6 in Portland to 21 Raleigh-Durham. Based on differences in the number and suite of endpoints related to urban intensity, these results provide evidence of differences in factors governing source strength, transport, and/or fate of hydrophobic compounds in the six metropolitan areas studied. The most consistent and significant results were that bioavailable, aryl hydrocarbon receptor agonists increase in streams as basins become urbanized. Potential toxicity mediated by this metabolic pathway is indicated as an important factor in the response of aquatic biota to urbanization.

Under CALFED, many different strategies were used to integrate science, including interaction between the research and management communities, public dialogues about scientific work, and peer review. This paper explores ways science was (and was not) integrated into CALFED's management actions and decision systems through three narratives describing different patterns of scientific integration and application in CALFED. Though a collaborative process and certain organizational conditions may be necessary for developing new understandings of the system of interest, we find that those factors are not sufficient for translating that knowledge into management actions and decision systems. We suggest that the application of knowledge may be facilitated or hindered by (1) differences in the objectives, approaches, and cultures of scientists operating in the research community and those operating in the management community and (2) other factors external to the collaborative process and organization.

Viable seeds of perennials were rare in undisturbed areas (3-4 seeds/m super(2)) and declined to < 1 seed/m super(2) within disturbed sites. Annual seed densities were an order of magnitude greater than those of perennials, were one-third the undisturbed seed densities on compacted sites, but doubled on trenched sites relative to controls. On trenched sites, greater litter cover comprising the infructescences of the dominant spring annuals, and low gravel content, enhanced seed densities of both annuals and perennials. Litter cover and surface ruggedness were the best explanations for viable perennial seed densities on compacted sites, but litter cover and the presence of a common harvester ant explained annual seed densities better than any other surface characteristics that were examined. Surface disturbances can have a varied impact on the condition of the soil surface in arid lands. Nevertheless, the consistently positive relationship between ground cover of litter and viable seed density emphasizes the importance of litter as an indicator of site degradation and recovery potential in arid lands.

Concern over the detrimental effects of these fluctuations prompted us to quantify the effects of variable flows on the amount and persistence of fall Chinook salmon spawning habitat in the Hanford Reach. Specifically, our goal was to develop a management tool capable of quantifying the effects of current and alternative hydrographs on predicted spawning habitat in a spatially explicit manner. Toward this goal, we modeled the water velocities and depths that fall Chinook salmon experienced during the 2004 spawning season, plus what they would probably have experienced under several alternative (i.e., synthetic) hydrographs, using both one- and two-dimensional hydrodynamic models. To estimate spawning habitat under existing or alternative hydrographs, we used cell-based modeling and logistic regression to construct and compare numerous spatial habitat models. We found that fall Chinook salmon were more likely to spawn at locations where velocities were persistently greater than 1 m/s and in areas where fluctuating water velocities were reduced. Simulations of alternative dam operations indicate that the quantity of spawning habitat is expected to increase as streamflow fluctuations are reduced during the spawning season. The spatial habitat models that we developed provide management agencies with a quantitative tool for predicting, in a spatially explicit manner, the effects of different flow regimes on fall Chinook salmon spawning habitat in the Hanford Reach. In addition to characterizing temporally varying habitat conditions, our research describes an analytical approach that could be applied in other highly variable aquatic systems.

Initial reports included unintentional poisoning of birds from ingestion of spent lead shot and predator control agents, alkali poisoning of waterbirds, and die-offs from maritime oil spills. With the advent of synthetic pesticides in the 1930s and 1940s, effects of DDT and other pesticides were investigated in free-ranging and captive wildlife. In response to research findings in the US and UK, and the publication of Silent Spring in 1962, public debate on the hazards of pollutants arose and national contaminant monitoring programs were initiated. Shortly thereafter, population-level effects of DDT on raptorial and fish-eating birds were documented, and effects on other species (e.g., bats) were suspected. Realization of the global nature of organochlorine pesticide contamination, and the discovery of PCBs in environmental samples, launched long-range studies in birds and mammals. With the birth of ecotoxicology in 1969 and the establishment of the Society of Environmental Toxicology and Chemistry in 1979, an international infrastructure began to emerge. In the 1980s, heavy metal pollution related to mining and smelting, agrichemical practices and non-target effects, selenium toxicosis, and disasters such as Chernobyl and the Exxon Valdez dominated the field. Biomarker development, endocrine disruption, population modeling, and studies with amphibians and reptiles were major issues of the 1990s. With the turn of the century, there was interest in new and emerging compounds (pharmaceuticals, flame retardants, surfactants), and potential population-level effects of some compounds. Based upon its history, wildlife toxicology is driven by chemical use and misuse, ecological disasters, and pollution-related events affecting humans. Current challenges include the need to more thoroughly estimate and predict exposure and effects of chemical-related anthropogenic activities on wildlife and their supporting habitat.

In the present study, PBDEs were detected in all 120 osprey (Pandion haliaetus) eggs collected. The eggs were collected from nests along the Columbia, Willamette and Yakima rivers of Oregon (OR) and Washington (WA) and in Puget Sound (WA) between 2002 and 2007. PBDE congeners: 17, 28, 47, 49, 66, 85, 99, 100, 138, 153, 154 (possible coelution with brominated biphenyl 153 [BB153]), 183, 190 (detected in one egg), 209 (not detected), and BB101 (only detected in 2006 and 2007) and total-a-hexabromocyclododecane (only detected in five eggs) were analyzed for in the egg samples. Eggs from reservoirs in the forested headwaters of the Willamette River (2002) contained the lowest concentrations of PBDEs (geometric mean [range], 98 [55.2-275] ng/g wet weight [ww]), while those from the middle Willamette River (2006) contained the highest (897 [507-1,880] ng/g ww). Concentrations in eggs from the Columbia River progressively increased downstream from Umatilla, OR (River Mile [RM] 286) to Skamokoa, WA (RM 29), which indicated additive PBDE sources along the river. In general, regardless of the year of egg collection, differences in PBDE concentrations reported in osprey eggs along the three major rivers studied (Columbia, Willamette and Yakima) seem to reflect differences in river flow (dilution effect) and the extent of human population and industry (source inputs) along the rivers. PBDE concentrations increased over time at two locations (Seattle, WA; Columbia River, RM 29-84) where temporal patterns could be evaluated. Only during 2006 (on the middle Willamette River, RM 61-157) and 2007 (on the lower Columbia River, RM 29-84) did PBDE concentrations in osprey eggs exceed 1,000ng/g ww with negative relationships indicated at both locations between productivity and PBDE concentrations in eggs (P=0.008, P=0.057). Osprey eggs from Everett, WA contained nearly twice the PBDE concentration (geometric mean 239 vs. 141ng/g ww, range 124-384 vs. 22.2-819ng/g ww, P,0.05) as double-crested cormorant (Phalacrocorax auritus) eggs collected at the same location and time, which is likely due to dietary differences. No significant relationship (all Ps>0.147) was indicated between PBDE congeners (including PBDEs) and eggshell thickness at the concentrations observed in this study.

Principal components analysis indicated that arsenic and uranium concentrations were associated with particle-tracking variables that simulate time of travel and water fluxes through aquifer systems and also through specific redox and pH zones within aquifers. Time-of-travel variables are important because many geochemical reactions are kinetically limited, and geochemical zonation can account for different modes of mobilization and fate. Spearman correlation analysis established statistical significance for correlations of arsenic and uranium concentrations with variables derived using the particle-tracking routines. Correlations between uranium concentrations and particle-tracking variables were generally strongest for variables computed for distinct redox zones. Classification tree analysis on arsenic concentrations yielded a quantitative categorical model using time-of-travel variables and solid-phase-arsenic concentrations. The classification tree model accuracy on the learning data subset was 70%, and on the testing data subset, 79%, demonstrating one application in which particle-tracking variables can be used predictively in a quantitative screening-level assessment of public supply well vulnerability. Ground-water management actions that are based on avoidance of young ground water, reflecting the premise that young ground water is more vulnerable to anthropogenic contaminants than is old ground water, may inadvertently lead to increased vulnerability to natural contaminants due to the tendency for concentrations of many natural contaminants to increase with increasing ground-water residence time.

It is endemic to Peninsular India and small parts of lowland Nepal. T. quadricornis is a sexually dimorphic boselaphid of small stature; only males have horns, with 2 of the 3 recognized subspecies having 2 anterior and 2 posterior smooth, sharp horns, unique among wild horned mammals. Tetracerus is monotypic. It prefers dry deciduous forested habitat and hilly terrain and is secretive and little studied. This diminutive species is considered Vulnerable by the International Union for Conservation of Nature and Natural Resources, and it is very uncommon in captivity.

However, most post-seeding monitoring does not address consequences to native flora. In November 2004, the US Forest Service hand-seeded triticale (Triticosecale Wittm. ex A. Camus), a sterile wheat-rye hybrid, on a small burned area in the Spring Mountains of southern Nevada, United States. A monitoring project using paired plots was designed to quantify the effects of seeding triticale on density and species richness of native annual and perennial plants, cover of perennial plants, and aboveground production of annual plants. We did not find any effects of triticale seeding on annual plant species or most responses of perennial plants. However, the density of woody perennial seedlings was significantly lower 2 years after triticale was added. Although we found a smaller impact from seeding with exotic grass than other studies, quantifiable costs to native vegetation were observed. We caution against the use of non-native grass for seeding in areas with naturally low perennial recruitment.

Upland and wetland soils, stream sediments and tailings were collected and analyzed for nutrients (DOC, SO sub(4) super(=), NO sub(3) super(-)), Hg, MeHg, and phospholipid fatty acids (PLFA). Stream sediment was derived from serpentinite, siltstone, volcanic rocks and mineralized serpentine with cinnabar, metacinnabar and other Hg phases. Soils from different parent materials had distinct PLFA biomass and community structures that are related to nutrient concentrations and toxicity effects of trace metals including Hg. The formation of MeHg appears to be most strongly linked to soil moisture, which in turn has a correlative relationship with PLFA biomass in wetland soils. The greatest concentrations of MeHg (>0.5 ng g super(-) super(1) MeHg) were measured in wetland soils and soil with a volcanic parent (9.5-37 ?g g super(-) super(1) Hg). Mercury methylation was associated with sulfate-reducing bacteria, including Desulfobacter sp. and Desulfovibrio sp., although these organisms are not exclusively responsible for Hg methylation. Statistical models of the data demonstrated that soil microbial communities varied more with soil type than with season.

CBNG co-produced water typically contains dissolved inorganic nitrogen (DIN), primarily as ammonium. In this study, a substantial portion of discharged ammonium was oxidized within 50 m of downstream transport, but speciation was markedly influenced by diel fluctuations in dissolved oxygen (>300 ?M). After 300 m of transport, 60% of the initial DIN load had been removed. The effect of benthic nitrogen-cycling processes on stream water chemistry was assessed at 2 locations within the stream channel using acrylic chambers to conduct short-term (2-6 h), in-stream incubations. The highest ambient DIN removal rates (2103 ?mol N m super(-) super(2) h super(-) super(1)) were found at a location where ammonium concentrations >350 ?M. This occurred during light incubations when oxygen concentrations were highest. Nitrification was occurring at the site, however, net accumulation of nitrate and nitrite accounted for <12% of the ammonium consumed, indicating that other ammonium-consuming processes were also occurring. In dark incubations, nitrite and nitrate consumption were dominant processes, while ammonium was produced rather than consumed. At a downstream location nitrification was not a factor and changes in DIN removal rates were controlled by nitrate reduction, diel fluctuations in oxygen concentration, and availability of electron donor. This study indicates that short-term adaptation of stream channel processes can be effective for removing CBNG DIN loads given sufficient travel distances, but the long-term potential for nitrogen remobilization and nitrogen saturation remain to be determined.

After documenting increased use of recently burned forests by boreal toads (Bufo boreas), we hypothesized that burned habitats provided improved thermal opportunities in terrestrial habitats. We tested this hypothesis by conducting a radio telemetry study of habitat use (reported previously) and by using physical models that simulated the temperature of adult toads. We deployed 108 physical models in and adjacent to a 1-year old burn using a fully-replicated design with three burn severities (unburned, partial, high severity) and four microhabitats (open surface, under vegetation, under log, in burrow). Model temperatures were compared to a range of preferred temperatures in published studies. We found 70% more observations within the preferred temperature range of B. boreas in forests burned with high severity than in unburned areas. Burned forest was warmer than unburned forest across all microhabitats, but the largest relative difference was in burrows, which averaged 3 super(o)C warmer in high-severity burn areas and remained warmer though the night. More than twice as many observations were within the preferred temperature range in high-severity burrows than in unburned burrows. Areas burned with high severity were still warmer than unburned forest 3 years after the fire. Habitat use of toads during the concurrent radio telemetry study matched that predicted by the physical models. These results suggest there are fitness-linked benefits to toads using burned habitats, such as increased growth, fertility, and possibly disease resistance. However, increased soil temperatures that result from wildfire may be detrimental to other amphibian species that prefer cooler temperatures and stable environments. More broadly, our data illustrate the use of physical models to measure and interpret changes that amphibians may experience from disturbance, and highlight the need for research linking vital rates such as growth and survival to disturbance.

Movement of selenium and other trace elements present in the lake bed sediments of GSL may occur due to periodic stratification displacement events or lake bed exposure. The water column of GSL is complicated by the presence of a chemocline persistent over annual to decadal time scales. The water below the chemocline is referred to as the deep brine layer (DBL), has a high salinity (16.5 to 22.9%) and is anoxic. The upper brine layer (UBL) resides above the chemocline, has lower salinity (12.6 to 14.7%) and is oxic. Displacement of the DBL may involve trace element movement within the water column due to changes in redox potential. Evidence of stratification displacement in the water column has been observed at two fixed stations on the lake by monitoring vertical water temperature profiles with horizontal and vertical velocity profiles. Stratification displacement events occur over periods of 12 to 24h and are associated with strong wind events that can produce seiches within the water column. In addition to displacement events, the DBL shrinks and expands in response to changes in the lake surface area over a period of months. Laboratory tests simulating the observed sediment re-suspension were conducted over daily, weekly and monthly time scales to understand the effect of placing anoxic bottom sediments in contact with oxic water, and the associated effect of trace element desorption and (or) dissolution. Results from the laboratory simulations indicate that a small percentage (1%) of selenium associated with anoxic bottom sediments is periodically solubilized into the UBL where it potentially can be incorporated into the biota utilizing the oxic part of GSL.

We analyzed the spatial ecology and habitat selection of Masticophis flagellum (the coachwhip) at three different scales to determine which habitats are most important to this species. Home ranges and mean daily displacements of M. flagellum in Florida were large compared to individuals in other populations of this species. Home ranges contained a greater proportion of Florida scrub habitat than did the study site as a whole, and individuals selected Florida scrub habitat within their home ranges. For both selection of the home range within the study site and selection of habitats within the home range, mesic cutthroat and hydric swamp habitats were avoided. Standardized selection ratios of Florida scrub patches were positively correlated with lizard abundance. Several non-mutually exclusive mechanisms, including foraging success (prey abundance, prey vulnerability, and foraging efficiency), abundance of refugia, and thermoregulatory opportunity may underlie the selection of Florida scrub by M. flagellum. Historic rarity and anthropogenic loss and fragmentation of Florida scrub habitat, coupled with the long-distance movements, large home ranges, and selection of Florida scrub by M. flagellum, indicate that large contiguous tracts of land containing Florida scrub will be essential for the persistence of M. flagellum in central Florida.

These anthropogenic ecosystems were once relatively common in the Northwest, but today are threatened because of the cessation of traditional resource management practices often coupled with widespread development and fire suppression. In this study, we explore the long-term history of Ebey's Prairie, an anthropogenic prairie on Whidbey Island, WA. We use analyses of soils, cultural features, archaeobotanical remains, and artifacts to demonstrate that people have been using the Ebey's Prairie locale for a variety of activities over a broad time scale (about 10,000 to 250 years B.P.). Within at least the last 2,300 years people began setting fires to create and maintain a "prairie" landscape. From that time onward, people used this landscape to harvest a range of open ecosystem resources. Understanding the long-term cultural and natural history of Ebey's and other prairies is a fundamental first step to managing these ecosystems for the future.

Here we report on 3 new records of P. subflavus from southeastern New Mexico, including the first 2 records from winter and the first record from spring. One individual in winter was observed hibernating in a cave in Chaves County. Our records and previous ones from autumn and summer suggest that this species is resident throughout the year in New Mexico.

Intraspecific ambient-density tests using cutthroat trout only were also performed. Results indicated an absence of cage effects in the stream enclosures and no differences in fish growth between ambient-density stream-enclosure fish and free-range fish. Brook trout outgrew and moved less than cutthroat trout in the stream enclosures, especially as density increased, In all 3 density treatments, brook trout gained more weight than cutthroat trout, with brook trout gaining weight in each density treatment and cutthroat trout losing weight at the highest density. At high densities, cutthroat trout attempted to emigrate more frequently than brook trout in sympatry and allopatry. We observed a negative correlation between growth and emigration for interspecific cutthroat trout, indicating a possible competitive response due to the presence of brook trout. We observed similar responses for weight and emigration in trials of allopatric cutthroat trout, indicating strong intraspecific effects as density increased. While cutthroat trout showed a response to experimental manipulation with brook trout at different densities, there has been long-term coexistence between these species in Beaver Creek, This system presents a unique opportunity to study the mechanisms that lead cutthroat trout to coexist with rather than be replaced by nonnative brook trout.

Ducks in Suisun fed primarily on seeds of Sea Purslane (Sesuvium verrucosum), followed by Alkali Bulrush (Schoenoplectus maritimus) and Wild Millet (Echinochloa crusgalli), together forming 73-90% (aggregate % dry mass) of the diets. Ducks in the Delta fed primarily on seeds of Smartweed (Polygonum spp.), followed by corn (Zea mays) and tomato seeds (Lycopersicon esculentum), together forming 62-88% of the diets. Pintails and Mallards collected in Suisun each had similar (5 of 11 seasonal comparisons) or greater (6 of the 11 comparisons) body mass compared to their conspecifics collected from the Delta (90% confidence interval analyses), despite a composite diet in the Delta having about 39% greater metabolizable energy content (ME) and 24% greater protein content than in Suisun. Therefore, diet quality alone was not a predictor of body mass in these two areas. Other factors must have been involved, such as greater food abundance and density, lower waterfowl abundance and density, or lower daily energy costs in Suisun. Direct measurement of these factors should explain the apparent inconsistencies in body mass relative to food quality in these brackish and freshwater habitats.

As illustrated by the Hurricane Ike example, synthetic aperture radar imaging capabilities are clearly applicable for emergency response operations, but they are also relevant to emergency environmental management. Integrated with optical monitoring, the nearly real-time availability of synthetic aperture radar provides superior consistency in status and trends monitoring and enhanced information concerning causal forces of change that are critical to coastal resource sustainability, including flooding extent, depth, and frequency.

For our study, we examined 202 individuals, 52 fresh hosts and 150 museum specimens, from New Mexico and southern Colorado for ectoparasites. We recorded 2158 ectoparasites, 634 from fresh hosts and 1524 from museum specimens. Ectoparasites belonged to 10 families and 13 genera of insect or acari and represent new host and locality records. In general, ectoparasites collected from fresh hosts and museum specimens were represented by 4 major species of mite: Macronyssus crosbyi, Alabidocarpus calcaratus, Acanthophthirius lucifugus, and Alabidocarpus nr. eptesicus. From our study, we found fresh hosts to have significantly greater prevalence values for Myodopsylla gentilis (flea), Chiroptonyssus robustipes (mite), and Leptotrombidium myotis (chigger), whereas museum specimens had significantly greater prevalence values for A. calcaratus (mite) and A. nr. eptesicus (mite). There were no significant differences between prevalence values for 4 mites including M. crosbyi, A. lucifugus, Pteracarus nr. minutus, and Cryptonyssus sp. Our study represents the only extensive study of ectoparasites on M. occultus and provides evidence for the importance of examining fresh hosts and museum specimens in future ectoparasite studies.

The methods that have been employed by the US Fish and Wildlife Service to estimate population density of desert tortoises are inadequate for detecting modest trends in population density, partly due to a hidden variance in a parameter (g sub(0)) that corrects for the proportion of tortoises that are inactive and thus unavailable for sampling when population density is being assessed. We used small dataloggers to record the activity of tortoises throughout their active season, and derived daily estimates of g sub(0), which we compared with the 2004 estimate published by the US Fish and Wildlife Service. Due to the substantial variation in animal activity that we found within and among days during the active season, we used a daily method to estimate density. We found that this method, while providing a more accurate assessment of g sub(0), translates into estimates of density with coefficients of variation that are 4x larger than previously reported due to the variation in g sub(0) and n (number of animals encountered). This discrepancy could adversely influence managers' perceptions of population recovery for desert tortoises, and could undermine any ability to monitor the efficacy of recovery actions for populations.

Wetlands, forests, and large urban areas surround the lake. Primary transport mechanisms of sediments to Lake Pontchartrain include urban runoff, major diversions of the Mississippi River, discharge from streams along the north and west shores, and tidal circulation. Sediments deposited in Lake Pontchartrain are subjected to resuspension and mixing by natural and human activities. Bioturbation and water turbulence throughout the lake are the major mixing agents, and mechanical shell dredging has reworked much of the lake bottom over the last century. Sediment characterization through direct sampling and geophysical surveys indicates that these processes continually rework the top meter of sediment.

The basin supports a variety of environments, from woodlands in the north to wetlands in the south, and a growing socioeconomic infrastructure that has led to rapid development of the southern half of the basin over the past two centuries. To properly administer this infrastructure, managers need to understand the complex geologic framework of the basin and how it will respond to continued sea-level rise, variable rates and magnitudes of land subsidence, and human alteration of the landscape. This article summarizes the body of work that describes the regional evolution and stratigraphic architecture of the Pontchartrain Basin.

Spectra for hematite-sorbed ocysts showed distinct changes in carboxylate group vibrations relative to spectra obtained in the absence of hematite, indicative of direct chemical bonding between carboxylate groups and Fe metal centers of the hematite surface. The data also indicate that complexation modes vary with solution chemistry. In NaCl solution, ocysts are bound to hematite via monodentate and binuclear bidentate complexes. The former predominates at low pH, whereas the latter becomes increasingly prevalent with increasing pH. In a CaCl2 solution, only binuclear bidentate complexes are observed. When solution pH is above the point of zero net proton charge (PZNPC) of hematite, ocyst surface carboxylate groups are bound to the mineral surface via outer-sphere complexes in both electrolyte solutions.

(2009) AN - 745639075; 12958187 AB - A Comment by Rey et al. (2009; Mar Ecol Prog Ser 389:295-300) documents disagreements with Middleton et al. (2008; Mar Ecol Prog Ser 371:117-129), which explored the characteristics of mangrove swamps managed for mosquito control in the Indian River Lagoon, Florida, USA. Rey et al. (2009) provide no data or evidence that invalidate the conclusions in Middleton et al. (2008). Most of the 'factual errors' and 'methodological problems' raised by Rey et al. (2009) are either unfounded or minor points, or reflect differences of opinion regarding appropriate sampling designs and techniques. The disagreement between the two research groups derives mainly from different scientific viewpoints. One is based on a parochial view guided by the immediate needs of local site managers; the other takes a wider view of ecology, which uses a landscape-level approach to develop information with broader application. This Reply Comment clarifies several issues, refocuses attention on the scientific aspects of this discussion, and summarizes information needed to develop a wider perspective for future management of coastal impoundments, especially given anticipated changes in climate, sea level, and other global factors. We discuss the challenges of studying complex ecological systems with the goal of providing useful information to managers, who must often make difficult decisions.

After 18 d on their respective mercury diets, the eggs of mallards fed 0.5, 1, 2, 4, or 8 microg/g mercury contained 97.8, 86.0, 89.9, 88.9, and 85.9%, respectively, of the peak concentrations reached after 23 d. Depending on the dietary concentration of mercury, no more than approximately a week may be required for harmful concentrations (0.5-0.8 microg/g, wet weight) to be excreted into eggs.

AN - 67671022; 19785272 AB - Rocky Mountain National Park is experiencing reduced visibility and changes in ecosystem function due to increasing levels of oxidized and reduced nitrogen. The Rocky Mountain Atmospheric Nitrogen and Sulfur (RoMANS) study was initiated to better understand the origins of sulfur and nitrogen species as well as the complex chemistry occurring during transport from source to receptor. As part of the study, a monitoring program was initiated for two 1-month time periods--one during the spring and the other during late summer/fall. The monitoring program included intensive high time resolution concentration measurements of aerosol number size distribution, inorganic anions, and cations, and 24-hr time resolution of PM2.5 and PM10 mass, sulfate, nitrate, carbon, and soil-related elements concentrations. These data are combined to estimate high time resolution concentrations of PM2.5 and PM10 aerosol mass and fine mass species estimates of ammoniated sulfate, nitrate, and organic and elemental carbon. Hour-by-hour extinction budgets are calculated by using these species concentration estimates and measurements of size distribution and assuming internal and external particle mixtures. Summer extinction was on average about 3 times higher than spring extinction. During spring months, sulfates, nitrates, carbon mass, and PM10 - PM2.5 mass contributed approximately equal amounts of extinction, whereas during the summer months, carbonaceous material extinction was 2-3 times higher than other species.

AN - 67663032; 19769100 AB - The effectiveness of mine-waste remediation at the Clark Fork River Superfund site in western Montana, USA, was examined by monitoring metal concentrations in resident biota (caddisfly, Hydropsyche spp.) and bed sediment over a 19-year period. Remediation activities began in 1990 and are ongoing. In the upper 45 km, reduced Cu and Cd concentrations at some sites were coincident with remediation events. However, for a period of three years, the decline in Cu and Cd directly below the treatment ponds was offset by high arsenic concentrations, suggesting that remediation for cations (e.g., Cu and Cd) mobilized anions such as arsenic. The impact of remediation in the middle and lower reaches was confounded by a significant positive relationship between metal bioaccumulation and stream discharge. High flows did not dilute metals but redistributed contaminants throughout the river. The majority of clean-up efforts were focused on reducing metal-rich sediments in the most contaminated upstream reach, implicitly assuming that improvements upstream will positively impact the downstream stations. We tested this assumption by correlating temporal metal trends in sediment between and among stations. The strength of that association (r value) was our indicator of spatial connectivity. Connectivity for both Cu and Cd was strong at small spatial scales. Large-scale connectivity was strongest with Cu since similar temporal reductions were observed at most monitoring stations. The most upstream station, closest to remediation, had the lowest connectivity, but the next three downstream sites were strongly correlated to trends downstream. Targeted remediation in this reach would be an effective approach to positively influencing the downstream stations.

AN - 67542073; 19643753 AB - The relation of bacterial pathogen occurrence to fecal indicator bacteria (FIB) concentrations used for recreational water quality criteria (RWQC) is poorly understood. This study determined the occurrence of Shiga-toxin producing Escherichia coli (STEC) markers and their relation to FIB concentrations in Michigan and Indiana river water. Using 67 fecal coliform (FC) bacteria cultures from 41 river sites in multiple watersheds, we evaluated the occurrence of five STEC markers: the Escherichia coli (EC) O157 antigen and gene, and the STEC virulence genes eaeA, stx1, and stx2. Simple isolations from selected FC cultures yielded viable EC O157. By both antigen and gene assays, EC O157 was detected in a greater proportion of samples exceeding rather than meeting FC RWQC (P < 0.05), but was unrelated to EC and enterococci RWQC. The occurrence of all other STEC markers was unrelated to any FIB RWQC. The eaeA, stx2, and stx1 genes were found in 93.3, 13.3, and in 46.7% of samples meeting FC RWQC and in 91.7, 0.0, and 37.5% of samples meeting the EC RWQC. Although not statistically significant, the percentage of samples positive for each STEC marker except stx1 was lower in samples that met, as opposed to exceeded, FIB RWQC. Viable STEC were common members of the FC communities in river water throughout southern Michigan and northern Indiana, regardless of FIB RWQC. Our study indicates that further information on the occurrence of pathogens in recreational waters, and research on alternative indicators of their occurrence, may help inform water-resource management and public health decision-making.

AN - 67540491; 19643755 AB - Understanding nutrient pathways to streams will improve nutrient management strategies and estimates of the time lag between when changes in land use practices occur and when water quality effects that result from these changes are observed. Nitrate and orthophosphate (OP) concentrations in several environmental compartments were examined in watersheds having a range of base flow index (BFI) values across the continental United States to determine the dominant pathways for water and nutrient inputs to streams. Estimates of the proportion of stream nitrate that was derived from groundwater increased as BFI increased. Nitrate concentration gradients between groundwater and surface water further supported the groundwater source of nitrate in these high BFI streams. However, nitrate concentrations in stream-bed pore water in all settings were typically lower than stream or upland groundwater concentrations, suggesting that nitrate discharge to streams was not uniform through the bed. Rather, preferential pathways (e.g., springs, seeps) may allow high nitrate groundwater to bypass sites of high biogeochemical transformation. Rapid pathway compartments (e.g., overland flow, tile drains) had OP concentrations that were typically higher than in streams and were important OP conveyers in most of these watersheds. In contrast to nitrate, the proportion of stream OP that is derived from ground water did not systematically increase as BFI increased. While typically not the dominant source of OP, groundwater discharge was an important pathway of OP transport to streams when BFI values were very high and when geochemical conditions favored OP mobility in groundwater.

We found significant effects that were most pronounced within 300m of the shore, but extended 3km inland via coyote scat deposition. The zone within 300m of the sea had a higher density of vegetation with a distinctly different plant composition. The denser vegetation supported higher abundances of birds and reptiles. Coyotes exhibited spatial and temporal responses to marine subsidies of fish, while birds were likely subsidized by aquatic aerial insects. Top-down control, as well as dietary and habitat preferences, may have resulted in reduced number of ants, beetles, and small mammals near the sea. Species responses to the habitat edge appeared to be associated with life history, as the near shore habitat favored habitat generalists and shore specialists, while inland desert habitat favored many sand and open desert specialists. Ecosystem responses support current theories of allochthonous spatial subsidies and consumer-resource dynamics but were limited in scope, magnitude, and distance.

AN - 21237576; 11725965 AB - We measured displacement, pore-water pressure, and climatic conditions for 3years at the continuously moving Slumgullion landslide in Colorado, USA. The landslide accelerated when pore-water pressure increased within the landslide body, but this occurred as pore-water pressure decreased along the landslide margin. The decrease probably occurred in response to shear-induced soil dilation at rates greater than pore-pressure diffusion and likely increased resistance to shear displacement and resulted in landslide deceleration. This dilative strengthening has been experimentally observed and explained theoretically, but not previously identified during field studies. Although landslide displacement should have exceeded that required to achieve critical-state density of shear boundaries, observed relocation of these boundaries indicates that shearing is episodic at fixed locations, so it permits renewed dilative strengthening when 'fresh' soil is sheared. Thus, dilatant strengthening may be a considerable mechanism controlling landslide velocity, even for landslides that have continuously moved great distances.

Global Positioning Systems either store the data on board the collar or contain a remote-transfer system that allows for data recovery at more frequent intervals. Spread spectrum (S-S) technology is a new mode of data transfer designed to overcome interference problems associated with narrow-band very high frequency and ultra high frequency data-transfer systems. We evaluated performance of S-S GPS radiocollars deployed on grizzly (Ursus arctos) and black bears (U. americanus). We also evaluated variables that influenced GPS fix success rates, with particular focus on animal activity, time of year, and temperature. The S-S GPS collars performed to our expectations and met study objectives; we did not experience any major problems with the data-transfer system. We observed varying rates of fix success that were directly related to recorded activity counts. Using logistic regression, we verified that activity counts were a reasonable measure of resting or feeding-traveling in both bear species. Our results showed that 73% and 79% of missed fixes, respectively, occurred when we predicted black and grizzly bears to be resting. Temperatures measured in the canister of the collar were not correlated with air temperature, suggesting posture and activity influenced canister temperature. Both measures of temperature were predictive of fix success. We did not find that fix success was related to body morphology (i.e., neck circumference, mass, and chest girth), fix interval, position of the GPS antenna relative to the sky, or sex of the bear. We conclude that fix success for both species is strongly related to activity patterns and time of year. Activity counters appear to be a reasonable measure of this behavior, and we recommend researchers consider including an activity-count system when deploying GPS collars. We also recommend researchers explore building separate models of habitat selection based upon categories of activity to account for bias in fix success associated with bear behavior.

Wildlife-forestry has been advocated for management of bottomland hardwood forests on public conservation lands within the Mississippi Alluvial Valley, USA. On Tensas River National Wildlife Refuge in northeast Louisiana, we used distance sampling during 6 visits to 138 point locations to estimate avian densities within stands subjected to variable-retention harvests, within a 13-year chronosequence, and untreated control stands. Densities of 9 species, including 6 species of conservation concern, were greater in treated stands than on untreated stands. Five species responded negatively to treatments and had greater densities in untreated control stands. Based on conservation concern scores established by Partners in Flight and annual detections of each of 30 species, treated stands afforded greater community-wide bird conservation than did untreated stands. For most species, maximum treatment response was between 5 years and 8 years posttreatment with duration of treatment effect <13 years. Therefore, habitat conditions on treated stands should be reevaluated at circa 15-year intervals and, if warranted, additional silvicultural treatment prescribed to rejuvenate habitat conditions.

Passerines dominated the avifauna numerically, comprising 97% of individuals surveyed but less than half of the 115 species recorded in the Preserve. We used distance-sampling and discrete-removal models to estimate detection probabilities, densities, and population sizes across the Preserve for 23 species of migrant passerines and five species of resident passerines. Yellow-rumped Warblers (Dendroica coronata) and Dark-eyed Juncos (Junco hyemalis) were the most abundant species, together accounting for 41% of the migrant passerine populations estimated. White-winged Crossbills (Loxia leucoptera), Boreal Chickadees (Poecile hudsonica), and Gray Jays (Perisoreus canadensis) were the most abundant residents. Species richness was greatest in the Floodplain/Terrace landform flanking the Yukon River but densities were highest in the Subalpine landform. Species composition was related to past glacial history and current physiography of the region and differed notably from other areas of the northwestern boreal forest. Point-transect surveys, augmented with auxiliary observations, were well suited to sampling the largely passerine avifauna across this rugged landscape and could be used across the boreal forest region to monitor changes in northern bird distribution and abundance.

Compared with chicks reared by non-handled adults that did not carry tags, deployment of tags on one or both adult parents ultimately resulted in 35% reduction in chick body mass and significantly reduced chick skeletal size preceding fledging (19 April). However, body mass between chick groups was not significantly different after controlling for skeletal size. Effects on chicks were more pronounced in six pairs where both parents carried tags. Chick mass was negatively related to the duration that adults carried tags. In this study, none of the chicks reared by pairs where both parents were tagged, 54% of chicks reared by pairs where one parent was tagged, and 83% of chicks reared by non-handled and non-tagged parents achieved a previously determined pre-fledging mass threshold (564 g; Sagar & Horning 1998). Body mass of adults carrying tags and returning from trans-equatorial migration the following year were 4% lighter on average than non-tagged birds, but this difference was not statistically significant. Reduced mass among chicks reared by adults carrying tags during the chick-provisioning period indicated that adults altered "normal" provisioning behaviours to maintain their own body condition at the expense of their chicks. Population-level information derived from telemetry studies can reveal important habitat-linked behaviours, unique aspects of sea-bird foraging behaviours, and migration ecology. Information for some species (e.g., overlap with fisheries) can aid conservation and marine ecosystem management. We advise caution, however, when interpreting certain data related to adult provisioning behaviours (e.g., time spent foraging, provisioning rates, etc.). If effects on individuals are of concern, we suggest shorter-term deployments, smaller and lighter tags, and alternative attachment techniques, especially when investigating threatened or endangered species.

Total PCB concentrations averaged 7.95 and 3.17 mg/kg for males and females, respectively. As part of the Natural Resource Damage Assessment remediation process, contaminated sediments from the Saginaw River, the main tributary to Saginaw Bay, were removed during 2000 and 2001. Total PCB concentrations of 10 male and 10 female walleyes caught at Dow Dam during April 2007 averaged 1.58 and 0.55 mg/kg, respectively. Thus, dredging of the Saginaw River appeared to be effective in reducing PCB concentrations of Saginaw Bay adult walleyes, as both males and females decreased in PCB concentration by more than 80% between 1996 and 2007. However, the ratio of male PCB concentration to female PCB concentration did not decline between 1996 and 2007. This persistent gender difference in PCB concentrations was apparently due to a gender difference in habitat utilization coupled with a persistent spatial gradient in prey fish PCB concentrations from the Saginaw River to Lake Huron.

Recent declines in deepwater sculpin abundance and changes in bathymetric distribution may be associated with changes in the deepwater food web of Lake Huron, particularly, decreased abundance of benthic invertebrates such as Diporeia. To assess how deepwater sculpins have responded to recent changes, we examined a fifteen-year time series of spatial and temporal patterns in abundance as well as the diets of fish collected in bottom trawls during fall of 2003, 2004, and 2005. During 1992-2007, deepwater sculpin abundance declined on a lake-wide scale but the decline in abundance at shallower depths and in the southern portion of Lake Huron was more pronounced. Of the 534 fish examined for diet analysis, 97% had food in the stomach. Mysis, Diporeia, and Chironomidae were consumed frequently, while sphaerid clams, ostracods, fish eggs, and small fish were found in only low numbers. We found an inverse relationship between prevalence of Mysis and Diporeia in diets that reflected geographic and temporal trends in abundance of these invertebrates in Lake Huron. Because deepwater sculpins are an important trophic link in offshore benthic food webs, declines in population abundance and changes in distribution may cascade throughout the food web and impede fish community restoration goals.

We surveyed nocturnal birds monthly during February-June 1998 at 19 stations along the Rio Grande (n = 6) and at upland stock ponds (n = 13) in Webb County, Texas. We conducted 10-min point counts (n = 89) after sunset and before moonset. Four species of owls and five species of nightjars were detected. Nightjars, as a group, were nearly five times more abundant (mean number/count = 2.63) than owls (mean number = 0.55). The most common owl, the great horned owl (Bubo virginianus), had a mean number of 0.25/point count. The mean for elf owls (Micrathene whitneyi) was 0.16/point count. The most common nightjars were the common poorwill (Phalaenoptilus nuttallii; 1.21/point count) and lesser nighthawk (Chordeiles acutipennis; 1.16/point count). Survey sites on the river supported more species (mean = 2.2) than did upland stock ponds (mean = 1.4). However, only one species (common pauraque, Nyctidromus albicollis) showed a preference for the river sites. Our results establish this segment of the Rio Grande in southern Texas as an area of high diversity of nightjars in the United States, matched (in numbers of species) only by southeastern Arizona and southwestern New Mexico.

We used NWI wetland maps and remotely sensed hydrologic data to map cypress-tupelo communities, surface water, and the extent and location of proposed regeneration condition classes for cypress-tupelo swamps in the Atchafalaya Basin, LA. Only 6,175 ha (5.8%) of the 106,227 ha of cypress-tupelo forest in the Lower Atchafalaya Basin Floodway was classified as capable of naturally regenerating. Over 23% (24,525 ha) of the forest area was mapped as unable to regenerate either naturally or artificially. The loss and conversion of nearly 25,000 ha of cypress-tupelo forest would have significant and long-lasting impacts on ecosystem services such as wildlife habitat for birds and Louisiana black bears. Given the landscape-scale changes in surface elevations and flooding depths and durations throughout southern Louisiana, similar conditions and impacts are likely applicable to all coastal cypress-tupelo forests in Louisiana. Better data on flooding during the growing season are needed to more accurately identify and refine the location and spatial extent of the regeneration condition classes.

Concentrations of perfluorooctane sulfonate, the major contributor to total PFC concentrations, were 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 ranking of PBDE congener concentrations by percent concentration (PBDE-47 > -99 > -100 > -153 > -154 > -28 > -183) was consistent with the Penta-PBDE formulation. Total PBDE concentrations in great blue heron eggs from Indiana Dunes were elevated and probably reflect local contamination from highly urbanized and industrialized inputs into Lake Michigan. Polybrominated diphenyl ether concentrations were within levels associated with altered reproductive behavior in other avian species and based on trends in other Great Lakes birds are probably higher today.

The relative contribution of subsidence and erosion to wetland loss can be estimated by comparing elevations and vertical offsets of stratigraphic contacts that are correlated between adjacent sediment cores. Accommodation-space measurements assume that wetland-sediment thicknesses and the elevation of stratigraphic contacts were originally nearly uniform over short horizontal distances (tens to hundreds of meters). The accommodation space attributable to erosion equals the difference in wetland-sediment thickness between wetland cores and adjacent open-water cores taken at formerly emergent wetland sites. The accommodation space attributable to subsidence equals the elevation difference of a stratigraphic marker correlated between the two cores using the wetland core as the reference standard. Together, subsidence plus erosion at an open-water core location equals the accommodation space created by land loss, which is the difference between the adjacent emergent wetland elevation and the existing water depth.

Around 1962 it invaded the Sacramento-San Joaquin Delta from upstream reservoirs, where it was stocked to support sport fisheries. It quickly became, and continues to be, one of the most abundant fishes collected by ongoing monitoring programs in the delta. A substantial portion of the delta provides suitable abiotic habitat and so the species is widely distributed. However, in routine sampling it is most commonly collected and most abundant in the southeastern delta, where suitable abiotic habitat (relatively deep, clear water with low flow) coincides with high prey abundance. Apparent growth rate appears to be relatively fast with summer-spawned age-0 fish attaining fork lengths of 70 to 90 mm by the onset of winter. During fall months (September through December) apparent growth rate of age-0 fish has exhibited no long-term trend but has been negatively related to abundance, suggesting that density-dependent factors may be important to the population. Although abundance has fluctuated since its introduction almost five decades ago, it has recently dropped to persistent near-record lows since 2002, which has been coincident with similar declines for other pelagic species in the delta. The recent decline is apparent in two long-term monitoring programs, fish salvaged from the diversions of the state and federal water projects, and commercial fishing harvest. It appears that the decline is, at least in part, a function of fewer and smaller schools of threadfin shad encountered relative to the past. There was little evidence from the data examined for consistent stock-recruit or stage-recruit effects on the population. It is likely that a combination of abiotic and biotic factors regionally-focused where threadfin shad are most abundant, which may sometimes be episodic in nature, have a large effect on abundance. Focused studies and sampling of threadfin shad are lacking but are necessary in order to better understand population dynamics in the delta.

We evaluated the association of local habitat features (width, gradient, and elevation), watershed characteristics (mean and maximum summer water temperatures, the number of road crossings, and road density), and biotic factors (the distance to the source of hybridization and trout density) with the spread of hybridization between native westslope cutthroat trout Oncorhynchus clarkii lewisi and introduced rainbow trout O. mykiss in the upper Flathead River system in Montana and British Columbia. The presence of hybridization and the proportion of rainbow trout admixture were estimated using seven diagnostic microsatellite loci. We defined logistic and linear regression models including various combinations of spatial and environmental factors and used an information-theoretic approach to evaluate the relative plausibility of these models. Models combining measures of water temperature, disturbance, and source connectivity were the best-approximating ones for the presence of hybridization. Hybridization was positively associated with mean summer water temperature and the number of upstream road crossings and negatively associated with the distance to the main source of hybridization. The best-approximating models associated with the level of introgression among hybridized sites included measures of temperature, source connectivity, and the density of trout. The proportion of rainbow trout admixture was negatively related to the distance to the source and positively related to mean summer water temperature and density. Our results suggest that hybridization is more likely to occur and spread in streams with warm water temperatures, increased land use disturbance, and proximity to the main source of hybridization. However, habitat features alone may not limit the spread of hybridization; populations with high proportions of admixture and high densities may have to be reduced or eliminated.

AN - 20834582; 11033373 AB - Winter distribution of Pacific Flyway brant (Branta bernicla nigricans) has shifted northward from low-temperate areas to sub-Arctic areas over the last 42 years. We assessed the winter abundance and distribution of brant in Alaska to evaluate whether climate warming may be contributing to positive trends in the most northern of the wintering populations. Mean surface air temperatures during winter at the end of the Alaska Peninsula increased about 1C between 1963 and 2004, resulting in a 23% reduction in freezing degree days and a 34% decline in the number of days when ice cover prevents birds from accessing food resources. Trends in the wintering population fluctuated with states of the Pacific Decadal Oscillation, increasing during positive (warm) phases and decreasing during negative (cold) phases, and this correlation provides support for the hypothesis that growth in the wintering population of brant in Alaska is linked to climate warming. The size of the wintering population was negatively correlated with the number of days of strong northwesterly winds in November, which suggests that the occurrence of tailwinds favorable for migration before the onset of winter was a key factor in whether brant migrated from Alaska or remained there during winter. Winter distribution of brant on the Alaska Peninsula was highly variable and influenced by ice cover, particularly at the heavily used Izembek Lagoon. Observations of previously marked brant indicated that the Alaska wintering population was composed primarily of birds originating from Arctic breeding colonies that appear to be growing. Numbers of brant in Alaska during winter will likely increase as temperatures rise and ice cover decreases at high latitudes in response to climate warming.

Invasive removal programs on islands are conservation efforts that can also be viewed as powerful manipulative experiments, but few data are available to evaluate their effects. We collected demographic and herbivore damage data for Castilleja mollis Pennell, an endangered plant endemic to Santa Rosa Island, California, over a 12-year period before, during, and after the implementation of control for introduced cattle, deer, and elk. We used these long-term data to explore mechanisms underlying herbivore effects, assess the results of herbivore reduction at the scales of both individual plants and populations, and determine how temporal variability in herbivory and plant demography influenced responses to herbivore removals. For individual plants, herbivore effects mediated by disturbance were greater than those of grazing. Deer and elk scraping of the ground substantially increased plant mortality arid dormancy and reduced flowering and growth. Stem damage from browsing did not affect survivorship but significantly reduced plant growth and flower production. Herbivore control successfully lowered damage rates, which declined steeply between 1997 and 2000 and have remained relatively low. Castilleja mollis abundances rose sharply after 1997, suggesting a positive effect of herbivore control, but then began to decline steadily again after 2003. The recent decline appears to be driven by higher mean growing season temperatures; interestingly, not only reductions in scraping damage but a period of cooler conditions were significant in explaining increases in C. mollis populations between 1997 and 2002. Our results demonstrate strong effects of introduced herbivores on both plant demography and population dynamics and show that climate-driven variation may counteract and mask positive responses to herbivore removal. Regional mean temperatures already have risen significantly over the last 50 years, suggesting that climate change could increasingly swamp the effects of management targeted at other environmental problems. Similar interactions between climate and invasive species will play an even greater role in future management, with long-term data sets like this critical to quantifying such effects.

AN - 20825853; 10982126 AB - Population control through harvest has the potential to reduce the abundance of nuisance and invasive species. However, demographic structure and density-dependent processes can confound removal efforts and lead to undesirable consequences, such as overcompensation (an increase in abundance in response to harvest) and instability (population cycling or chaos). Recent empirical studies have demonstrated the potential for increased mortality (such as that caused by harvest) to lead to overcompensation and instability in plant, insect, and fish populations. We developed a general population model with juvenile and adult stages to help determine the conditions under which control harvest efforts can produce unintended outcomes. Analytical and simulation analyses of the model demonstrated that the potential for overcompensation as a result of harvest was significant for species with high fecundity, even when annual stage-specific survivorship values were fairly low. Population instability as a result of harvest occurred less frequently and was only possible with harvest strategies that targeted adults when both fecundity and adult survivorship were high. We considered these results in conjunction with current literature on nuisance and invasive species to propose general guidelines for assessing the risks associated with control harvest based on life history characteristics of target populations. Our results suggest that species with high per capita fecundity (over discrete breeding periods), short juvenile stages, and fairly constant survivorship rates are most likely to respond undesirably to harvest. It is difficult to determine the extent to which overcompensation and instability could occur during real-world removal efforts, and more empirical removal studies should be undertaken to evaluate population-level responses to control harvests. Nevertheless, our results identify key issues that have been seldom acknowledged and are potentially generic across taxa.

This paper presents automated methods to prune network and polygon features of the United States high-resolution National Hydrography Dataset (NHD) to lower resolutions. Feature-pruning rules, data enrichment, and partitioning are derived from knowledge of surface water, the NHD model, and associated feature specification standards. Relative prominence of network features is estimated from upstream drainage area (UDA). Network and polygon features are pruned by UDA and NHD reach code to achieve a drainage density appropriate for any less detailed map scale. Data partitioning maintains local drainage density variations that characterize the terrain. For demonstration, a 48 subbasin area of 1:24 000-scale NHD was pruned to 1:100 000-scale (100K) and compared to a benchmark, the 100K NHD. The coefficient of line correspondence (CLC) is used to evaluate how well pruned network features match the benchmark network. CLC values of 0.82 and 0.77 result from pruning with and without partitioning, respectively. The number of polygons that remain after pruning is about seven times that of the benchmark, but the area covered by the polygons that remain after pruning is only about 10% greater than the area covered by benchmark polygons.

This interest has been motivated by the important role that these substances play in physiological processes such as photosynthesis, their relationships with ecosystem processes such as litter decomposition and nutrient cycling, and their use in identifying key plant species and functional groups. This paper reviews three areas of research to improve the application of imaging spectrometers to quantify non-pigment biochemical constituents of plants. First, we examine recent empirical and modeling studies that have advanced our understanding of leaf and canopy reflectance spectra in relation to plant biochemistry. Next, we present recent examples of how spectroscopic remote sensing methods are applied to characterize vegetation canopies, communities and ecosystems. Third, we highlight the latest developments in using imaging spectrometer data to quantify net primary production (NPP) over large geographic areas. Finally, we discuss the major challenges in quantifying non-pigment biochemical constituents of plant canopies from remotely sensed spectra.

Sediment cores and high-resolution bathymetric and seismic reflection data were collected from the lake during the fall of 1999 and 2000. Sediments were analyzed for diatoms, pollen, density, grain size (sand/mud ratio), total organic carbon (TOC), and micro-scale fabric analysis. Using both super(14)C (AMS) dating and tephrochronology, the basal sediments were estimated to have been deposited about 11,400calyear BP, thus yielding an estimated average sedimentation rate of about 20.66cm/1,000year. The lowermost part of the core (11,400-10,300calyear BP) contains the transition from glacial to interglacial conditions. From about 11,000-5,500calyear BP, Medicine Lake consisted of two small, steep-sided lakes or one lake with two steep-sided basins connected by a shallow shelf. During this time, both the pollen (Abies/Artemisia ratio) and the diatom (Cyclotella/Navicula ratio) evidences indicate that the effective moisture increased, leading to a deeper lake. Over the past 5,500years, the pollen record shows that effective moisture continued to increase, and the diatom record indicates fluctuations in the lake level. The change in the lake level pattern from one of the increasing depths prior to about 6,000calyear BP to one of the variable depths may be related to changes in the morphology of the Medicine Lake caldera associated with the movement of magma and the eruption of the Medicine Lake Glass Flow about 5,120calyear BP. These changes in basin morphology caused Medicine Lake to flood the shallow shelf which surrounds the deeper part of the lake. During this period, the Cyclotella/Navicula ratio and the percent abundance of Isoetes vary, suggesting that the level of the lake fluctuated, resulting in changes in the shelf area available for colonization by benthic diatoms and Isoetes. These fluctuations are not typical of the small number of low-elevation Holocene lake records in the region, and probably reflect the hydrologic conditions unique to Medicine Lake.

We compare concentrations of environmental contaminants in red-throated loons among four nesting areas in Alaska and discuss potential ramifications of exposure on reproductive success and population trends. Eggs from the four areas had similar total polychlorinated biphenyl (PCB) concentrations, but eggs from the Arctic coastal plain had different congener profiles and greater toxic equivalents (TEQs) than eggs from elsewhere. Satellite telemetry data indicate that red-throated loons from the Arctic coastal plain in northern Alaska winter in southeast Asia, while those breeding elsewhere in Alaska winter in North America. Different wintering areas may lead to differential PCB accumulation among red-throated loon populations. For eggs from the Arctic coastal plain, TEQs were great enough to postulate PCB-associated reproductive effects in piscivores. The correlation between migration patterns and PCB profiles suggests that red-throated loons breeding in northern Alaska are exposed to PCBs while on their Asian wintering grounds.

Fish community attributes were compared to watershed features and to physical and chemical variables including metal concentrations in sediment pore water and fish. Ozark sculpin (Cottus hypselurus), rainbow darter (Etheostoma caeruleum), Ozark madtom (Noturus albater), and banded sculpin (Cottus carolinae) were the most abundant fishes collected. Species richness and density of riffle-dwelling benthic fishes were negatively correlated with metal concentrations in pore water and in fish. Sculpin densities were also negatively correlated with metal concentrations in pore water and in fish, but positively correlated with distance from mines and upstream watershed area. These findings indicate that metals associated with active lead-zinc mining adversely affect riffle-dwelling benthic fishes downstream of mining areas in the Viburnum Trend. Sculpins may be useful as a sentinel species for assessing mining-related impacts on fish communities.

We measured incoming and outgoing sediment across a gradient of soil disturbance (livestock grazing, plowing) and annual plant invasion for 9 years. Our sites included two currently ungrazed sites: one never grazed by livestock and dominated by perennial grasses/well-developed biocrusts and one not grazed since 1974 and dominated by annual weeds with little biocrusts. We used two currently grazed sites: one dominated by annual weeds and the other dominated by perennial plants, both with little biocrusts. Precipitation was highly variable, with years of average, above-average, and extremely low precipitation. During years with average and above-average precipitation, the disturbed sites consistently produced 2.8 times more sediment than the currently undisturbed sites. The never grazed site always produced the least sediment of all the sites. During the drought years, we observed a 5600-fold increase in sediment production from the most disturbed site (dominated by annual grasses, plowed about 50 years previously and currently grazed by livestock) relative to the never grazed site dominated by perennial grasses and well-developed biocrusts, indicating a non-linear, synergistic response to increasing disturbance types and levels. Comparing sediment losses among the sites, biocrusts were most important in predicting site stability, followed by perennial plant cover. Incoming sediment was similar among the sites, and while inputs were up to 9-fold higher at the most heavily disturbed site during drought years compared to average years, the change during the drought conditions was small relative to the large change seen in the sediment outputs.

One aim of the program was to determine the strength and effectiveness of local cross-shelf transport processes. A particular objective was to assess the ability of semidiurnal internal tidal currents to move suspended material a net distance across the shelf. Hence, a dense array of moorings was deployed across the shelf to monitor the transport patterns associated with fluctuations in currents, temperature and salinity. An associated hydrographic program periodically monitored synoptic changes in the spatial patterns of temperature, salinity, nutrients and bacteria. This set of measurements show that a series of energetic internal tides can, but do not always, transport subthermocline water, dissolved and suspended material from the middle of the shelf into the surfzone. Effective cross-shelf transport occurs only when (1) internal tides at the shelf break are strong and (2) subtidal currents flow strongly downcoast. The subtidal downcoast flow causes isotherms to tilt upward toward the coast, which allows energetic, nonlinear internal tidal currents to carry subthermocline waters into the surfzone. During these events, which may last for several days, the transported water remains in the surfzone until the internal tidal current pulses and/or the downcoast subtidal currents disappear. This nonlinear internal tide cross-shelf transport process was capable of carrying water and the associated suspended or dissolved material from the mid-shelf into the surfzone, but there were no observation of transport from the shelf break into the surfzone. Dissolved nutrients and suspended particulates (such as phytoplankton) transported from the mid-shelf into the nearshore region by nonlinear internal tides may contribute to nearshore algal blooms, including harmful algal blooms that occur off local beaches.

The goal of this study was to better understand sediment dynamics in a coral reef-lined embayment where winds, ocean surface waves, and river floods are important processes. During a summer period that was marked by two wave events and one river flood, we documented significant differences in sediment trap collection rates and the composition, grain size, and magnitude of sediment transported in the bay. Sediment trap collection rates were well correlated with combined wave-current near-bed shear stresses during the non-flood periods but were not correlated during the flood. The flood's delivery of fine-grained sediment to the bay initially caused high turbidity and sediment collection rates off the river mouth but the plume dispersed relatively quickly. Over the next month, the flood deposit was reworked by mild waves and currents and the fine-grained terrestrial sediment was advected around the bay and collected in sediment traps away from the river mouth, long after the turbid surface plume was gone. The reworked flood deposits, due to their longer duration of influence and proximity to the seabed, appear to pose a greater long-term impact to benthic coral reef communities than the flood plumes themselves. The results presented here display how spatial and temporal differences in hydrodynamic processes, which result from variations in reef morphology and orientation, cause substantial variations in the deposition, residence time, resuspension, and advection of both reef-derived and fluvial sediment over relatively short spatial scales in a coral reef embayment.

Previous studies have shown that land cover change detection strongly depends on spatial scale. However, the influence of the spatial resolution of land cover change information on the estimated terrestrial carbon sequestration is not known. Here, we quantified and evaluated the impact of land cover change databases at various spatial resolutions (250 m, 500 m, 1 km, 2 km, and 4 km) on the magnitude and spatial patterns of regional carbon sequestration in the southeastern United States using the General Ensemble biogeochemical Modeling System (GEMS). Results indicated a threshold of 1 km in the land cover change databases and in the estimated regional terrestrial carbon sequestration. Beyond this threshold, significant biases occurred in the estimation of terrestrial carbon sequestration, its interannual variability, and spatial patterns. In addition, the overriding impact of interannual climate variability on the temporal change of regional carbon sequestration was unrealistically overshadowed by the impact of land cover change beyond the threshold. The implications of these findings directly challenge current continental- to global-scale carbon modeling efforts relying on information at coarse spatial resolution without incorporating fine-scale land cover dynamics.

On Lake Sakakawea of the upper Missouri River, 37 and 70% of Piping Plover (Charadrius melodus) nests found in 2007 and 2008, respectively, were initiated at elevations inundated prior to projected hatch date. We describe eight events at seven nests in which adult Piping Plovers appeared to have moved active nests threatened by rising water or gathered eggs apparently displaced by rising water on Lake Sakakawea and the Garrison reach of the upper Missouri River. Additionally, we describe one nest that was moved after the habitat at the nest site had been disturbed by domestic cattle. Our observations and evidence indicate that adult Piping Plovers are capable of moving eggs and establishing nests at new sites during incubation. Furthermore, our results suggest that Piping Plovers evaluate their reproductive investment under potential threat of nest loss and may be capable of acting prospectively (moving nests prior to inundation) and reactively (regathering eggs after inundation) to avoid nest failure.

AN - 67638141; 19731653 AB - Perchlorate (ClO4-) is a common groundwater constituent with both synthetic and natural sources. A potentially important source of ClO4- is past agricultural application of ClO4(-)-bearing natural NO3- fertilizer imported from the Atacama Desert, Chile, but evidence for this has been largely circumstantial. Here we report ClO4- stable isotope data (delta37Cl, delta18O, and delta17O), along with other supporting chemical and isotopic environmental tracer data, to document groundwater ClO4 contamination sources and history in parts of Long Island, New York. Sampled groundwaters were oxic and ClO4- apparently was not affected by biodegradation within the aquifers. Synthetic ClO4- was indicated by the isotopic method in groundwater near a fireworks disposal site at a former missile base. Atacama ClO4- was indicated in agricultural and urbanizing areas in groundwaters with apparent ages > 20 years. In an agricultural area, ClO4- concentrations and ClO4-/NO3- ratios increased with groundwater age, possibly because of decreasing application rates of Atacama NO3- fertilizers and/or decreasing ClO4- concentrations in Atacama NO3- fertilizers in recent years. Because ClO4-/NO3- ratios of Atacama NO3- fertilizers imported in the past (approximately 2 x 10(-3) mol mol(-1)) were much higher than the CO4-/NO3- ratio of recommended drinking-water limits (7 x 10(-5) mol mol(-1) in New York), ClO4- could exceed drinking-water limits even where NO3- does not, and where Atacama NO3- was only a minor source of N. Groundwater ClO4- with distinctive isotopic composition was a sensitive indicator of past Atacama NO3- fertilizer use on Long Island and may be common in other areas that received NO3- fertilizers from the late 19th century through the 20th century.

AN - 67636764; 19731660 AB - Fipronil is a potent insecticide used for control of termites, fleas, roaches, ants, and other pests. We measured fipronil, fipronil sulfide, and desulfinyl fipronil concentrations in indoor and outdoor dust from 24 residences in Austin, Texas. At least one of these three fipronil compounds was detected in every sample. Fipronil accounted for most of the total fipronil (T-fipronil; fipronil + desulfinyl fipronil + fipronil sulfide), followed by desulfinyl fipronil and fipronil sulfide. Nineteen of 24 samples of indoor dust had T-fipronil concentrations less than 270 microg/kg; the remaining five had concentrations from 1320 to 14,200 microg/kg. All three of the residences with a dog on which a flea-control product containing fipronil was used were among the five residences with elevated fipronil concentrations. In outdoor dust all concentrations of T-fipronil were less than 70 microg/kg with one exception (430 microg/kg). For every residence, the concentration of T-fipronil in indoor dust exceeded that in outdoor dust, and the median concentration of T-fipronil was 15 times higher indoors than outdoors.

AN - 67613612; 19374473 AB - Organochlorines were examined in liver and stable isotopes in muscle of fishes from the western Aleutian Islands, Alaska, in relation to islands or locations affected by military occupation. Pacific cod (Gadus macrocephalus), Pacific halibut (Hippoglossus stenolepis), and rock greenling (Hexagrammos lagocephalus) were collected from nearshore waters at contemporary (decommissioned) and historical (World War II) military locations, as well as at reference locations. Total (Sigma) polychlorinated biphenyls (PCBs) dominated the suite of organochlorine groups (SigmaDDTs, Sigmachlordane cyclodienes, Sigmaother cyclodienes, and Sigmachlorinated benzenes and cyclohexanes) detected in fishes at all locations, followed by SigmaDDTs and Sigmachlordanes; dichlorodiphenyldichloroethylene (p,p'DDE) composed 52 to 66% of SigmaDDTs by species. Organochlorine concentrations were higher or similar in cod compared to halibut and lowest in greenling; they were among the highest for fishes in Arctic or near Arctic waters. Organochlorine group concentrations varied among species and locations, but SigmaPCB concentrations in all species were consistently higher at military locations than at reference locations. Moreover, all organochlorine group concentrations were higher in halibut from military locations than those from reference locations. A wide range of molecular weight organochlorines was detected at all locations, which implied regional or long-range transport and deposition, as well as local point-source contamination. Furthermore, a preponderance of higher-chlorinated PCB congeners in fishes from contemporary military islands implied recent exposure. Concentrations in all organochlorine groups increased with delta15N enrichment in fishes, and analyses of residual variation provided further evidence of different sources of SigmaPCBs and p,p'DDE among species and locations.

AN - 67471091; 19555287 AB - Primary pneumonic plague is a rare but often fatal form of Yersinia pestis infection that results from direct inhalation of bacteria and is potentially transmissible from person to person. We describe a case of primary pneumonic plague in a wildlife biologist who was found deceased in his residence 1 week after conducting a necropsy on a mountain lion. To determine cause of death, a postmortem examination was conducted, and friends and colleagues were interviewed. Physical evidence was reviewed, including specimens from the mountain lion and the biologist's medical chart, camera, and computer. Human and animal tissues were submitted for testing. Persons in close contact (within 2 meters) to the biologist after he had developed symptoms were identified and offered chemoprophylaxis. The biologist conducted the necropsy in his garage without the use of personal protective equipment. Three days later, he developed fever and hemoptysis and died approximately 6 days after exposure. Gross examination showed consolidation and hemorrhagic fluid in the lungs; no buboes were noted. Plague was diagnosed presumptively by polymerase chain reaction and confirmed by culture. Tissues from the mountain lion tested positive for Y. pestis, and isolates from the biologist and mountain lion were indistinguishable by pulsed-field gel electrophoresis. Among 49 contacts who received chemoprophylaxis, none developed symptoms consistent with plague. The biologist likely acquired pneumonic plague through inhalation of aerosols generated during postmortem examination of an infected mountain lion. Enhanced awareness of zoonotic diseases and appropriate use of personal protective equipment are needed for biologists and others who handle wildlife.

AN - 67412487; 19468666 AB - This study was conducted to support a Natural Resource Damage Assessment and Restoration project associated with the Ashtabula River in Ohio. The objective of the study was to evaluate the chemistry and toxicity of 50 sediment samples obtained from five cores collected from the Ashtabula River (10 samples/core, with each 10-cm-diameter core collected to a total depth of about 150 cm). Effects of chemicals of potential concern (COPCs) measured in the sediment samples were evaluated by measuring whole-sediment chemistry and whole-sediment toxicity in the sediment samples (including polycyclic aromatic hydrocarbons [PAHs], polychl
