Using a geographic information system (GIS), wells were selected that were likely to draw water that had been in contact with lignite; control wells were located in areas devoid of lignite deposits. Well water samples were analyzed for pH, conductivity, organic compounds, and nutrient and anion concentrations. All samples were further tested for presence of fungi (cultures maintained for up to 28 days and colonies counted and identified microscopically) and for metal and trace element concentration by inductively-coupled plasma mass spectrometry and atomic emission spectrometry. Surface water samples were tested for dissolved oxygen and presence of pathogenic leptospiral bacteria. The Spearman correlation method was used to assess the association between the endpoints for these field/laboratory analyses and incidence of cancer of the renal pelvis (RPC) based on data obtained from the Louisiana Tumor Registry for the five Parishes included in the study. Significant associations were revealed between the cancer rate and the presence in drinking water of organic compounds, the fungi Zygomycetes, the nutrients PO4 and NH3, and 13 chemical elements. Presence of human pathogenic leptospires was detected in four out of eight (50%) of the surface water sites sampled. The present study of a stable rural population examined possible linkages between aquifers containing chemically reactive lignite deposits, hydrologic conditions favorable to the leaching and transport of toxic organic compounds from the lignite into the groundwater, possible microbial contamination, and RPC risk. ??

Geologic mapping shows that initial dissolution and inception of cave development is concentrated just beneath sandstone beds within Upper Cambrian and Lower Ordovician dolostone. Although rocks of the Ozarks have systematic and pervasive vertical joints, the development of karst conduits is controlled by bedding planes and stratigraphic variability. In the Salem Plateau of south-central Missouri, sinkholes occur in the lower part of the Ordovician Roubidoux Formation, where sinkholes are rimmed with and contain sandstone that has collapsed into voids in the underlying Ordovician Gasconade Dolomite. Cave diving by the Ozark Cave Diving Alliance into Alley Spring, a large (average flow 3.7 m3/s) spring along the Jacks Fork in the Ozark National Scenic Riverways, shows that although the spring discharges from the middle part of the Gasconade, the source of water is a cave passage just beneath the Gunter Sandstone Member of the Gasconade Dolomite. Artesian conditions cause the upward movement of groundwater from cavernous dolostone beneath the sandstone aquitards to the large springs. We hypothesize that sandstone, which is largely impermeable due to silica cementation, acts as a confining unit where hydraulic pressure, combined with mixing of water of differing chemistry, increases dissolution in the underlying dolostone beds. ?? 2006 Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Special Paper of the Geological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/2006.2404(04)","issn":"00721077","usgsCitation":"Orndorff, R.C., Weary, D., and Harrison, R., 2006, The role of sandstone in the development of an Ozark karst system, south-central Missouri: Special Paper of the Geological Society of America, no. 404, p. 31-38, https://doi.org/10.1130/2006.2404(04).","startPage":"31","endPage":"38","numberOfPages":"8","costCenters":[],"links":[{"id":215402,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/2006.2404(04)"},{"id":243204,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"404","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505baf95e4b08c986b3248d7","contributors":{"authors":[{"text":"Orndorff, R.

Associated with this growth has been a change in landscape from natural cover types to developed urban land mixed with planned vegetation canopy throughout in the metropolitan area. Air quality in the Las Vegas Valley has been affected by increases in anthropogenic emissions and concentrations of carbon monoxide, ozone, and criteria pollutants of particular matter. Ozone concentration in the region is generally influenced by synoptic and mesoscale meteorological conditions, as well as regional transport of pollutants from the western side of Las Vegas. Local influences from ground-level nitrogen oxide emissions and vegetation canopy coverage also affect ozone concentration. Multi-year observational data collected by a network of local air monitoring stations in Clark County, Nevada, indicate that ozone maximums develop in May and June, while minimums exist primarily from November to February. Ozone concentrations are high on the west and northwest sides of the valley. A nighttime ozone reduction in the urban area characterizes the heterogeneous features of spatial distribution for average ozone levels in the Las Vegas urban area. The urban vegetation canopy has a locally positive effect by reducing ozone in urban areas. Decreased ozone levels associated with increased urban development density suggests that the highest ozone concentrations are associated with medium- to low-density urban development in Las Vegas.","largerWorkTitle":"86th AMS Annual Meeting","conferenceTitle":"86th AMS Annual Meeting","conferenceDate":"29 January 2006 through 2 February 2006","conferenceLocation":"Atlanta, GA","language":"English","usgsCitation":"Xian, G., and Crane, M., 2006, The study of ozone variations in the Las Vegas metropolitan area using remote sensing information and ground observations, <i>in</i> 86th AMS Annual Meeting, Atlanta, GA, 29 January 2006 through 2 February 2006.","numberOfPages":"8","costCenters":[],"links":[{"id":243945,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb09fe4b08c986b324f95","contributors":{"authors":[{"text":"Xian, G. 0000-0001-5674-2204","orcid":"https://orcid.org/0000-0001-5674-2204","contributorId":65656,"corporation":false,"usgs":true,"family":"Xian","given":"G.","affiliations":[],"preferred":false,"id":451708,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Crane, M.","contributorId":86957,"corporation":false,"usgs":true,"family":"Crane","given":"M.","email":"","affiliations":[],"preferred":false,"id":451709,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Van Valen's Red Queen hypothesis triggered three decades of research testing its primary implication: that age is independent of extinction. In contrast to this, later studies with species-level data have indicated the possible presence of age dependence. Since the formulation of the Red Queen hypothesis, more powerful tests of survivorship models have been developed. This is the first report of the application of the Cox Proportional Hazards model to paleontological data. Planktonic foraminiferal morphospecies allow the taxonomic and precise stratigraphic resolution necessary for the Cox model. As a whole, planktonic foraminiferal morphospecies clearly show age-dependent extinction. In particular, the effect is attributable to the presence of shorter-ranged species (range < 4 myr) following extinction events. These shorter-ranged species also possess tests with unique morphological architecture. The morphological differences are probably epiphenomena of underlying developmental and heterochronic processes of shorter-ranged species that survived various extinction events. Extinction survivors carry developmental and morphological characteristics into postextinction recovery times, and this sets them apart from species populations established independently of extinction events.

All Upper Devonian sites and virtually all Early Carboniferous faunas are regarded as predominantly aquatic and most occur within, or are associated with, wetland habitats. A new mid- Carboniferous (Elvirian, Namurian A) fossil locality in Kentucky preserves the fi rst tetrapod fauna from the eastern portion of the Illinois Basin. Four distinct facies at the locality have yielded vertebrate material. Diverse faunas have been found in an abandoned channel/oxbow facies and a fl oodplain/lake facies. The abandoned channel/oxbow facies contains Colosteidae, Embolomeri, Rhizodontida, Dipnoi, Xenacanthiformes, Palaeonisciformes, and Gyracanthidae remains. This assemblage is similar to known Mississippian freshwater and brackishwater faunas, providing further evidence of a cosmopolitan tetrapod province during the Mississippian. A different fauna, rich in tetrapods but lacking fi sh, is associated with granular carbonate masses, rooting structures, and a paleosol in the fl oodplain/ lake facies. Isolated and associated tetrapod elements from this facies exhibit morphological adaptations that may suggest a fauna of more highly terrestrial vertebrates than previously known from the North American Mississippian. ?? 2006 Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Special Paper of the Geological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/2006.2399(08)","issn":"00721077","usgsCitation":"Garcia, W., Storrs, G., and Greb, S., 2006, The Hancock County tetrapod locality: A new Mississippian (Chesterian) wetlands fauna from western Kentucky (USA): Special Paper of the Geological Society of America, no. 399, p. 155-167, https://doi.org/10.1130/2006.2399(08).","startPage":"155","endPage":"167","numberOfPages":"13","costCenters":[],"links":[{"id":215094,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/2006.2399(08)"},{"id":242868,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"399","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba76de4b08c986b321569","contributors":{"authors":[{"text":"Garcia, W.J.","contributorId":38379,"corporation":false,"usgs":true,"family":"Garcia","given":"W.J.","email":"","affiliations":[],"preferred":false,"id":449930,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Storrs, G.W.","contributorId":74170,"corporation":false,"usgs":true,"family":"Storrs","given":"G.W.","email":"","affiliations":[],"preferred":false,"id":449932,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Greb, S.F.","contributorId":48294,"corporation":false,"usgs":true,"family":"Greb","given":"S.F.","email":"","affiliations":[],"preferred":false,"id":449931,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Although many general ecological patterns have been established, often a significant amount of the spatial and temporal variation in soft-sediment communities within and among systems remains unexplained. Here we propose a framework that may aid in unraveling the complex influence of environmental factors associated with the different components of coastal systems (i.e. the terrestrial and benthic landscapes, and the hydrological seascape) on benthic communities, and use this information to assess the role played by benthos in coastal ecosystems. A primary component of the approach is the recognition of system modules (e.g. marshes, dendritic systems, tidal rivers, enclosed basins, open bays, lagoons). The modules may differentially interact with key forcing functions (e.g. temperature, salinity, currents) that influence system processes and in turn benthic responses and functions. Modules may also constrain benthic characteristics and related processes within certain ecological boundaries and help explain their overall spatio-temporal variation. We present an example of how benthic community characteristics are related to the modular structure of 14 coastal seas and estuaries, and show that benthic functional group composition is significantly related to the modular structure of these systems. We also propose a framework for exploring the role of benthic communities in coastal systems using this modular approach and offer predictions of how benthic communities may vary depending on the modular composition and characteristics of a coastal system. ?? 2006 Elsevier B.V.

Natural and anthropogenic changes in hydrology and geomorphology at local and landscape levels have reduced the productivity in many of these coastal wetland forests areas and have caused the complete loss of forest cover in some places. A summary and interpretation of the available science, suggestions for policy change, and a multidisciplinary (multi-responsibility) approach were needed to address these issues [in the context of private land]. In response, the Louisiana Governor's office formed a Coastal Wetland Forest Conservation and Use Science Working Group (SWG) and an associated Advisory Panel to provide the Governor with information and suggestions of strategies for environmental and economic utilization, conservation, and protection of Louisiana's coastal wetland forest ecosystem in the long-term. The process of engaging scientists, resource managers, and other stakeholders in this effort is described, and the recommendations of the SWG are presented relative to forestry practices and the potential for sustainable management of coastal wetland forests.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Hydrology and management of forested wetlands - Proceeding of the international conference","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"International Conference on Hydrology and Management of Forested Wetlands","conferenceDate":"April 8-12, 2006","conferenceLocation":"New Bern, NC","language":"English","publisher":"ASABE","doi":"10.13031/2013.20309","isbn":"1892769530; 9781892769534","usgsCitation":"Chambers, J.L., Conner, W., Keim, R., Faulkner, S., Day, J., Gardiner, E., Hughes, M., King, S., McLeod, K., Miller, C., Nyman, J., and Shaffer, G., 2006, Towards sustainable management of Louisiana's coastal wetland forests: Problems, constraints, and a new beginning, <i>in</i> Hydrology and management of forested wetlands - Proceeding of the international conference, New Bern, NC, April 8-12, 2006, p. 150-157, https://doi.org/10.13031/2013.20309.","productDescription":"8 p.","startPage":"150","endPage":"157","numberOfPages":"8","costCenters":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"links":[{"id":240995,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Louisiana","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -89.835205078125,\n              30.732392734006083\n            ],\n            [\n              -93.790283203125,\n              30.372875188118016\n            ],\n            [\n              -93.834228515625,\n              29.726222319395504\n            ],\n            [\n              -93.31787109374999,\n              29.707139348134145\n            ],\n            [\n              -92.2412109375,\n              29.48742484748479\n            ],\n            [\n              -92.054443359375,\n              29.516110386062277\n            ],\n            [\n              -91.845703125,\n              29.420460341013133\n            ],\n            [\n              -91.56005859375,\n              29.554345125748267\n            ],\n            [\n              -91.285400390625,\n              29.180941290001776\n            ],\n            [\n              -90.977783203125,\n              29.123373210819224\n            ],\n            [\n              -90.648193359375,\n              28.969700808694157\n            ],\n            [\n              -89.80224609374999,\n              29.19053283229458\n            ],\n            [\n              -89.395751953125,\n              28.844673680771795\n            ],\n            [\n              -88.890380859375,\n              29.19053283229458\n            ],\n            [\n              -89.09912109375,\n              30.06909396443887\n            ],\n            [\n              -89.56054687499999,\n              30.20211367909724\n            ],\n            [\n              -89.835205078125,\n              30.732392734006083\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb5c2e4b08c986b3268a8","contributors":{"authors":[{"text":"Chambers, J.

For a Poisson process, the wait times between successive events occur statistically with an exponential density function. Fitting an exponential function to the durations between successive large Kp events forms the basis of our analysis. Defining these wait times by calculating the differences between times when Kp exceeds a certain value, such as Kp ??? 5, we find the wait-time distribution is not exponential. Because large storms often have several periods with large Kp values, their occurrence in time is not memoryless; short duration wait times are not independent of each other and are often clumped together in time. If we remove same-storm large Kp occurrences, the resulting wait times are very nearly exponentially distributed and the storm arrival process can be characterized as Poisson. Fittings are performed on wait time data for Kp ??? 5, 6, 7, and 8. The mean wait times between storms exceeding such Kp thresholds are 7.12, 16.55, 42.22, and 121.40 days respectively.","language":"English","publisher":"AGU","doi":"10.1029/2006GL026687","issn":"00948276","usgsCitation":"Remick, K., and Love, J.J., 2006, Statistical modeling of storm-level Kp occurrences: Geophysical Research Letters, v. 33, no. 16, Article L16102; 4 p., https://doi.org/10.1029/2006GL026687.","productDescription":"Article L16102; 4 p.","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":477533,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2006gl026687","text":"Publisher Index Page"},{"id":236285,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209625,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2006GL026687"}],"volume":"33","issue":"16","noUsgsAuthors":false,"publicationDate":"2006-08-22","publicationStatus":"PW","scienceBaseUri":"505b9734e4b08c986b31b946","contributors":{"authors":[{"text":"Remick, K.J.","contributorId":78139,"corporation":false,"usgs":true,"family":"Remick","given":"K.J.","email":"","affiliations":[],"preferred":false,"id":421015,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Love, Jeffrey J. 0000-0002-3324-0348 jlove@usgs.gov","orcid":"https://orcid.org/0000-0002-3324-0348","contributorId":760,"corporation":false,"usgs":true,"family":"Love","given":"Jeffrey","email":"jlove@usgs.gov","middleInitial":"J.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":421014,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We examined the effects of rainbow trout introductions on the native westslope cutthroat trout O. c. lewisii within the Stehekin River drainage, North Cascades National Park, Washington, by analyzing 1,763 salmonid DNA samples from 18 locations with nine diagnostic nuclear DNA markers and one diagnostic mitochondrial DNA (mtDNA) marker. Pure westslope cutthroat trout populations only occurred above upstream migration barriers in the Stehekin River and Park Creek. Two categories of rainbow trout admixture were observed: (1) less than 10% within the Stehekin River drainage above the Bridge Creek confluence and the middle and upper Bridge Creek drainage and (2) greater than 30% within the Stehekin River below the Bridge Creek confluence and in lower Bridge Creek. Hybrid indices and multilocus genotypes revealed an absence of rainbow trout and reduced hybrid diversity within the Stehekin River above the Bridge Creek confluence relative to hybrid diversity in the Stehekin River below the confluence and within lower Bridge Creek. Cytonuclear disequilibrium statistics revealed assortative mating between westslope cutthroat and rainbow trout but not among hybrids within the same locations.

Midwater trawling showed that mature female lake herring were largely pelagic during the night in late November, accounting for 94.5% of all fish caught exceeding 250 mm total length.

Though renowned as hotspots for the accumulation of mercury and its transformation to the toxic methylmercury, boreal wetlands might soon transition to hotspots for atmospheric mercury emissions. Estimates of circumboreal mercury emissions from this study are 15-fold greater than estimates that do not account for mercury stored in peat soils. Ongoing and projected increases in boreal wildfire activity due to climate change will increase atmospheric mercury emissions, contributing to the anthropogenic alteration of the global mercury cycle and exacerbating mercury toxicities for northern food chains.

One influence on these circulation patterns is the longitudinal density gradient. In most estuaries the longitudinal density gradient typically maintains a constant direction. However, a junction of tidal channels can create a local reversal (change in sign) of the density gradient. This can occur due to a difference in the phase of tidal currents in each channel. In San Francisco Bay, the phasing of the currents at the junction of Mare Island Strait and Carquinez Strait produces a local salinity minimum in Mare Island Strait. At the location of a local salinity minimum the longitudinal density gradient reverses direction. This paper presents four numerical models that were used to investigate the circulation caused by the salinity minimum: (1) A simple one-dimensional (1D) finite difference model demonstrates that a local salinity minimum is advected into Mare Island Strait from the junction with Carquinez Strait during flood tide. (2) A three-dimensional (3D) hydrodynamic finite element model is used to compute the tidally averaged circulation in a channel that contains a salinity minimum (a change in the sign of the longitudinal density gradient) and compares that to a channel that contains a longitudinal density gradient in a constant direction. The tidally averaged circulation produced by the salinity minimum is characterized by converging flow at the bed and diverging flow at the surface, whereas the circulation produced by the constant direction gradient is characterized by converging flow at the bed and downstream surface currents. These velocity fields are used to drive both a particle tracking and a sediment transport model. (3) A particle tracking model demonstrates a 30 percent increase in the residence time of neutrally buoyant particles transported through the salinity minimum, as compared to transport through a constant direction density gradient. (4) A sediment transport model demonstrates increased deposition at the near-bed null point of the salinity minimum, as compared to the constant direction gradient null point.

Circular albedo features on Titan's surface, seen at 2.02 ??m, may be palimpsests remaining from the rheological adjustment of ancient impact craters. As such, their long-term persistence is of special interest in view of the expected precipitation of liquids and solids from the atmosphere. Saturn's rings have changed little in their radial structure since the Voyager flybys in the early 1980s.

Amplitudes of the horizontal components of shear-wave arrivals from three local earthquakes were used to compute SSRs with respect to the average of two bedrock sites and H/V spectral ratios with respect to the vertical component of the shear-wave arrivals at each site. SSR site-response curves at thick basin sites show peak amplifications of 2 to 6 at frequencies of 3 to 6 Hz, and decreasing spectra amplification with increasing frequency above 6 Hz. SSRs at nonbasin sites show a variety of shapes and larger resonance peaks. We attribute the spectral decay at frequencies above the amplification peak at basin sites to attenuation within the basin strata. Computing the frequency-independent, depth-dependent attenuation factor (Qs,int) from the SSR spectral decay between 2 and 20 Hz gives values of 5 to 40 for shallow sedimentary deposits and about 250 for the deepest sedimentary strata (7 km depth). H/V site responses show less spectral decay than the SSR responses but contain many of the same resonance peaks. We hypothesize that the H/V method yields a flatter response across the frequency spectrum than SSRs because the H/V reference signal (vertical component of the shear-wave arrivals) has undergone a degree of attenuation similar to the horizontal component recordings. Correcting the SSR site responses for attenuation within the basins by removing the spectral decay improves agreement between SSR and H/V estimates.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120040200","issn":"00371106","usgsCitation":"Pratt, T.L., and Brocher, T., 2006, Site response and attenuation in the Puget Lowland, Washington State: Bulletin of the Seismological Society of America, v. 96, no. 2, p. 536-552, https://doi.org/10.1785/0120040200.","startPage":"536","endPage":"552","numberOfPages":"17","costCenters":[],"links":[{"id":238916,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":211600,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120040200"}],"volume":"96","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b90f5e4b08c986b319702","contributors":{"authors":[{"text":"Pratt, T.

We also collected 1 y of monitoring data for amphibian populations and incorporated the results into the inventory. Detection probabilities and site occupancy estimates for four species, the Pinewoods Treefrog (Hyla femoralis), Pig Frog (Rana grylio), Southern Leopard Frog (R. sphenocephala) and Carpenter Frog (R. virgatipes) are presented here. Detection probabilities observed in this study indicate that spring and summer surveys offer the best opportunity to detect these species in the Refuge. Results of the inventory suggest that substantial changes may have occurred in the amphibian fauna within and adjacent to the swamp.

Between June and August, the geochemical content of rock glacier outflow does not appear to differ substantially from that of other surface waters in the Green Lakes Valley. Thus, for this alpine ecosystem at this time of year there does not appear to be large differences in water quality among rock glacier outflow, glacier and blockslope discharge, and discharge from small alpine catchments. However, in September concentrations of Mg2+ in the outflow of the rock glacier increased to more than 900 ??eq L-1 compared to values of less than 40 ??eq L-1 at all the other sites, concentrations of Ca2+ were greater than 4,000 ??eq L-1 compared to maximum values of less than 200 ??eq L-1 at all other sites, and concentrations of SO42- reached 7,000 ??eq L-1, compared to maximum concentrations below 120 ??eq L-1 at the other sites. Inverse geochemical modelling suggests that dissolution of pyrite, epidote, chlorite and minor calcite as well as the precipitation of silica and goethite best explain these elevated concentrations of solutes in the outflow of the rock glacier. Three component hydrograph separation using end-member mixing analysis shows that melted snow comprised an average of 30% of RG5 outflow, soil water 32%, and base flow 38%. Snow was the dominant source water in June, soil water was the dominant water source in July, and base flow was the dominant source in September. Enrichment of ?? 18O from - 10??? in the outflow of the rock glacier compared to -20??? in snow and enrichment of deuterium excess from +17.5??? in rock glacier outflow compared to +11??? in snow, suggests that melt of internal ice that had undergone multiple melt/freeze episodes was the dominant source of base flow.

Predictions of the survival of discarded fish are dependent on understanding how a fish responds to stressful conditions. Our objective was to describe the immunological health of sablefish exposed to capture stressors. In laboratory experiments designed to simulate the capture process, we subjected sablefish to various stressors that might influence survival: towing in a net, hooking, elevated seawater and air temperatures, and air exposure time. After stress was imposed, the in vitro mitogen-stimulated proliferation of sablefish leukocytes was used to evaluate the function of the immune system in an assay we validated for this species. The results demonstrated that regardless of fishing gear type, exposure to elevated seawater temperature, or time in air, the leukocytes from stressed sablefish exhibited significantly diminished proliferative responses to the T-cell mitogen, concanavalin A, or the B-cell mitogen, lipopolysaccharide. There was no difference in the immunological responses associated with seawater or air temperature. The duration and severity of the capture stressors applied in our study were harsh enough to induce significantly elevated levels of plasma cortisol and glucose, but there was no difference in the magnitude of levels among stressor treatments. These data suggest that immunological suppression occurs in sablefish subjected to capture-related stressors. The functional impairment of the immune system after capture presents a potential reason why delayed mortality is possible in discarded sablefish. Further studies are needed to determine whether delayed mortality in discarded sablefish can be caused by increased susceptibility to infectious agents resulting from stressor-mediated immunosuppression.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the American Fisheries Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1577/T04-198.1","issn":"00028487","usgsCitation":"Lupes, S., Davis, M., Olla, B., and Schreck, C., 2006, Capture-related stressors impair immune system function in sablefish: Transactions of the American Fisheries Society, v. 135, no. 1, p. 129-138, https://doi.org/10.1577/T04-198.1.","startPage":"129","endPage":"138","numberOfPages":"10","costCenters":[],"links":[{"id":211651,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/T04-198.1"},{"id":238979,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"135","issue":"1","noUsgsAuthors":false,"publicationDate":"2011-01-09","publicationStatus":"PW","scienceBaseUri":"5059f355e4b0c8380cd4b725","contributors":{"authors":[{"text":"Lupes, S.C.","contributorId":84975,"corporation":false,"usgs":true,"family":"Lupes","given":"S.C.","email":"","affiliations":[],"preferred":false,"id":430266,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Davis, M.W.","contributorId":51083,"corporation":false,"usgs":true,"family":"Davis","given":"M.W.","email":"","affiliations":[],"preferred":false,"id":430265,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Olla, B.L.","contributorId":10602,"corporation":false,"usgs":true,"family":"Olla","given":"B.L.","affiliations":[],"preferred":false,"id":430263,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Schreck, C.B.","contributorId":11977,"corporation":false,"usgs":true,"family":"Schreck","given":"C.B.","email":"","affiliations":[],"preferred":false,"id":430264,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Postlarvae entering the nursery grounds of Florida Bay were collected for three consecutive years at channels that connect the Bay with the Gulf of Mexico, and in channels of the Middle Florida Keys that connect the southeastern margin of the Bay with the Atlantic Ocean.

In contrast, the greater postlarval influx occurred at the northwestern border of the Bay, where there was a strong seasonal pattern with peaks in influx from July through September each year. Planktonic stages need to travel up to 150 km eastward between spawning grounds (northeast of Dry Tortugas) and nursery grounds (western Florida Bay) in about 30 days, the estimated time of planktonic development for this species. A Lagrangian trajectory model was developed to estimate the drift of planktonic stages across the SW Florida shelf. The model simulated the maximal distance traveled by planktonic stages under various assumptions of behavior. &nbsp;Simulation results indicated that larvae traveling with the instantaneous current and exhibiting a diel behavior travel up to 65 km and 75% of the larvae travel only 30 km. However, the eastward distance traveled increased substantially when a larval response to tides was added to the behavioral variable (distance increased to 200 km and 85% of larvae traveled 150 km). The question is, when during larval development, and where on the shallow SW Florida shelf, does the tidal response become incorporated into the behavior of pink shrimp.</p>","language":"English","publisher":"U.S. Government Printing Office","publisherLocation":"Washington, D.C.","issn":"00900656","usgsCitation":"Criales, M.M., Wang, J.D., Browder, J.A., Robblee, M.B., Jackson, T.L., and Hittle, C.D., 2006, Variability in supply and cross-shelf transport of pink shrimp (<i>Farfantepenaeus duorarum</i>) postlarvae into western Florida Bay: Fishery Bulletin, v. 104, no. 1, p. 60-74.","productDescription":"15 p.","startPage":"60","endPage":"74","numberOfPages":"15","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":238947,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":319626,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://fishbull.noaa.gov/1041/1041toc.htm"}],"country":"United States","state":"Florida","otherGeospatial":"Dry Tortugas, Florida Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -79.91455078125,\n              25.94816628853973\n            ],\n            [\n              -79.9200439453125,\n              25.54244147012483\n            ],\n            [\n              -80.2166748046875,\n              25.04081549894912\n            ],\n            [\n              -80.8648681640625,\n              24.56211235799689\n            ],\n            [\n              -81.5789794921875,\n              24.412140070651528\n            ],\n            [\n              -82.6336669921875,\n              24.382124181118236\n            ],\n            [\n              -83.07861328125,\n              24.45215015618098\n            ],\n            [\n              -83.1060791015625,\n              24.696934226366672\n            ],\n            [\n              -82.5787353515625,\n              24.806681353851964\n            ],\n            [\n              -81.3262939453125,\n              24.926294766395593\n            ],\n            [\n              -80.760498046875,\n              25.224820176765036\n            ],\n            [\n              -80.4364013671875,\n              25.606855993715016\n            ],\n            [\n              -80.343017578125,\n              25.849336891707605\n            ],\n            [\n              -80.2056884765625,\n              25.93828707492375\n            ],\n            [\n              -80.04638671875,\n              25.96792222903405\n            ],\n            [\n              -79.91455078125,\n              25.94816628853973\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"104","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc12fe4b08c986b32a492","contributors":{"authors":[{"text":"Criales, Maria M.","contributorId":69330,"corporation":false,"usgs":false,"family":"Criales","given":"Maria","email":"","middleInitial":"M.","affiliations":[{"id":12565,"text":"Rosenstiel School of Atomospheric Science, University of Miami","active":true,"usgs":false}],"preferred":false,"id":430260,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wang, John D.","contributorId":75224,"corporation":false,"usgs":true,"family":"Wang","given":"John","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":430261,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Browder, Joan A.","contributorId":7439,"corporation":false,"usgs":true,"family":"Browder","given":"Joan","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":430257,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Robblee, Michael B. mike_robblee@usgs.gov","contributorId":3865,"corporation":false,"usgs":true,"family":"Robblee","given":"Michael","email":"mike_robblee@usgs.gov","middleInitial":"B.","affiliations":[],"preferred":true,"id":430258,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Jackson, Thomas L.","contributorId":93667,"corporation":false,"usgs":true,"family":"Jackson","given":"Thomas","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":430262,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Hittle, Clinton D. cdhittle@usgs.gov","contributorId":2436,"corporation":false,"usgs":true,"family":"Hittle","given":"Clinton","email":"cdhittle@usgs.gov","middleInitial":"D.","affiliations":[],"preferred":true,"id":430259,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Catchments at the Fort Benning Military Installation (near Columbus, Georgia) experience a range of upland disturbance intensities due to spatial variability in the intensity of military training. We used this disturbance gradient to investigate the effects of upland soil and vegetation disturbance on stream chemistry. During baseflow, mean total suspended sediment (TSS) concentration and mean inorganic suspended sediment (ISS) concentration increased with catchment disturbance intensity (TSS: R2 = 0.7, p = 0.005, range = 4.0-10.1 mg L-1; ISS: R2 = 0.71, p = 0.004, range = 2.04-7.3 mg L-1); dissolved organic carbon (DOC) concentration (R2 = 0.79, p = 0.001, range = 1.5-4.1 mg L-1) and soluble reactive phosphorus (SRP) concentration (R2 = 0.75, p = 0.008, range = 1.9-6.2 ??g L-1) decreased with increasing disturbance intensity; and ammonia (NH 4+), nitrate (NO3-), and dissolved inorganic nitrogen (DIN) concentrations were unrelated to disturbance intensity. The increase in TSS and ISS during storms was positively correlated with disturbance (R2 = 0.78 and 0.78, p = 0.01 and 0.01, respectively); mean maximum change in SRP during storms increased with disturbance (r = 0.7, p = 0.04); and mean maximum change in NO3- during storms was marginally correlated with disturbance (r = 0.58, p = 0.06). Soil characteristics were significant predictors of baseflow DOC, SRP, and Ca 2+, but were not correlated with suspended sediment fractions, any nitrogen species, or pH. Despite the largely intact riparian zones of these headwater streams, upland soil and vegetation disturbances had clear effects on stream chemistry during baseflow and stormflow conditions. ??
