Five cores yielded the following major deep-sea genera: Krithe, Henryhowella, Poseidonamicus, Legitimocythere, Pseudobosquetina, and Pennyella. All genera are widely distributed in abyssal depths in the world's oceans and common in Cenozoic deep-sea sediments. The total number of ostracod specimens is higher and ostracod shell preservation is better near the sediment-water interface, especially at the 0-1 cm core depths. Core slices from ???5 to 10 cm were barren or yielded a few poorly preserved specimens. The DIVA2 cores show that deep-sea ostracod species inhabit corrosive bottom water near the carbonate compensation depth (CCD) even though their calcareous valves are rarely preserved as fossils in sediment cores due to postmortem dissolution. Their occurrence at great water depths may partially explain the well-known global distributions of major deep-sea taxa in the world's oceans, although further expeditions using minimal-disturbance sampling devices are needed to fill geographic gaps. ?? 2008 Elsevier Ltd.

We assessed the distribution and abundance of spawning, non-spawning adult and larval capelin in Glacier Bay, an estuarine fjord system in southeastern Alaska. We used principal components analysis to analyze midwater trawl and beach seine data collected between 1999 and 2004 with respect to oceanographic data and other measures of physical habitat including proximity to tidewater glaciers and potential spawning habitat. Both spawning and non-spawning adult Pacific capelin were more likely to occur in areas closest to tidewater glaciers, and those areas were distinguished by lower temperature, higher turbidity, higher dissolved oxygen and lower chlorophyll a levels when compared with other areas of the bay. The distribution of larval Pacific capelin was not sensitive to glacial influence. Pre-spawning females collected farther from tidewater glaciers were at a lower maturity state than those sampled closer to tidewater glaciers, and the geographic variation in the onset of spawning is likely the result of differences in the marine habitat among sub-areas of Glacier Bay. Proximity to cold water in Glacier Bay may have provided a refuge for capelin during the recent warm years in the Gulf of Alaska.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Fisheries Oceanography","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2419.2008.00470.x","issn":"10546006","usgsCitation":"Arimitsu, M.L., Piatt, J.F., Litzow, M.A., Abookire, A.A., Romano, M.D., and Robards, M.D., 2008, Distribution and spawning dynamics of capelin (Mallotus villosus) in Glacier Bay, Alaska: A cold water refugium: Fisheries Oceanography, v. 17, no. 2, p. 137-146, https://doi.org/10.1111/j.1365-2419.2008.00470.x.","startPage":"137","endPage":"146","numberOfPages":"10","costCenters":[],"links":[{"id":242452,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214704,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2419.2008.00470.x"}],"volume":"17","issue":"2","noUsgsAuthors":false,"publicationDate":"2008-03-27","publicationStatus":"PW","scienceBaseUri":"505a02a3e4b0c8380cd5013e","contributors":{"authors":[{"text":"Arimitsu, Mayumi L. 0000-0001-6982-2238 marimitsu@usgs.gov","orcid":"https://orcid.org/0000-0001-6982-2238","contributorId":140501,"corporation":false,"usgs":true,"family":"Arimitsu","given":"Mayumi","email":"marimitsu@usgs.gov","middleInitial":"L.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":433570,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Piatt, John F. 0000-0002-4417-5748 jpiatt@usgs.gov","orcid":"https://orcid.org/0000-0002-4417-5748","contributorId":3025,"corporation":false,"usgs":true,"family":"Piatt","given":"John","email":"jpiatt@usgs.gov","middleInitial":"F.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":433573,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Litzow, Michael A.","contributorId":8789,"corporation":false,"usgs":true,"family":"Litzow","given":"Michael","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":433569,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Abookire, Alisa A.","contributorId":107224,"corporation":false,"usgs":true,"family":"Abookire","given":"Alisa","email":"","middleInitial":"A.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":false,"id":433574,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Romano, Marc D.","contributorId":73528,"corporation":false,"usgs":true,"family":"Romano","given":"Marc","email":"","middleInitial":"D.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":false,"id":433572,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Robards, Martin D.","contributorId":40148,"corporation":false,"usgs":false,"family":"Robards","given":"Martin","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":433571,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Vp versus depth relations were developed from borehole, laboratory, seismic refraction and tomography, and density measurements, and were converted to Vs versus depth relations using new empirical relations between Vp and Vs. The relations proposed here account for increasing overburden pressure but not for variations in other factors that can influence velocity over short distance scales, such as lithology, consolidation, induration, porosity, and stratigraphic age. Standard deviations of the misfits predicted by these relations thus provide a measure of the importance of the variability in Vp and Vs caused by these other factors. Because gabbros, greenstones, basalts, and other mafic rocks have a different Vp and Vs relationship than sedimentary and granitic rocks, the differences in Vs between these rock types at depths below 6 or 7 km are generally small. The new relations were used to derive the 2005 U.S. Geological Survey seismic velocity model for northern California employed in the broadband strong motion simulations of the 1989 Loma Prieta and 1906 San Francisco earthquakes; initial tests of the model indicate that the Vp model generally compares favorably to regional seismic tomography models but that the Vp and Vs values proposed for the Franciscan Complex may be about 5% too high.","largerWorkTitle":"Bulletin of the Seismological Society of America","language":"English","doi":"10.1785/0120060403","issn":"00371106","usgsCitation":"Brocher, T., 2008, Compressional and shear-wave velocity versus depth relations for common rock types in northern California, <i>in</i> Bulletin of the Seismological Society of America, v. 98, no. 2, p. 950-968, https://doi.org/10.1785/0120060403.","startPage":"950","endPage":"968","numberOfPages":"19","costCenters":[],"links":[{"id":242637,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214881,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120060403"}],"volume":"98","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f947e4b0c8380cd4d53d","contributors":{"authors":[{"text":"Brocher, T.M. 0000-0002-9740-839X","orcid":"https://orcid.org/0000-0002-9740-839X","contributorId":69994,"corporation":false,"usgs":true,"family":"Brocher","given":"T.M.","affiliations":[],"preferred":false,"id":434804,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

In partnership with the U.S. Department of Energy and with scientific assistance from the U.S. Geological Survey and academic partners, the JIP has focused on studies to assess hazards associated with drilling the fine-grained, hydrate-bearing sediments that dominate much of the shallow subseafloor in the deepwater (&gt;500 m) Gulf of Mexico. In preparation for an initial drilling, logging, and coring program, the JIP sponsored a multi-year research effort that included: (a) the development of borehole stability models for hydrate-bearing sediments; (b) exhaustive laboratory measurements of the physical properties of hydrate-bearing sediments; (c) refinement of new techniques for processing industry-standard 3-D seismic data to constrain gas hydrate saturations; and (d) construction of instrumentation to measure the physical properties of sediment cores that had never been removed from in situ hydrostatic pressure conditions. Following review of potential drilling sites, the JIP launched a 35-day expedition in Spring 2005 to acquire well logs and sediment cores at sites in Atwater Valley lease blocks 13/14 and Keathley Canyon lease block 151 in the northern Gulf of Mexico minibasin province. The Keathley Canyon site has a bottom simulating reflection at ???392 m below the seafloor, while the Atwater Valley location is characterized by seafloor mounds with an underlying upwarped seismic reflection consistent with upward fluid migration and possible shoaling of the base of the gas hydrate stability (BGHS). No gas hydrate was recovered at the drill sites, but logging data, and to some extent cores, suggest the occurrence of gas hydrate in inferred coarser-grained beds and fractures, particularly between 220 and 330 m below the seafloor at the Keathley Canyon site. This paper provides an overview of the results of the initial phases of the JIP work and introduces the 15 papers that make up this special volume on the scientific results related to the 2005 logging and drilling expedition.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.marpetgeo.2008.02.007","issn":"02648","usgsCitation":"Ruppel, C., Boswell, R., and Jones, E., 2008, Scientific results from Gulf of Mexico Gas Hydrates Joint Industry Project Leg 1 drilling: Introduction and overview: Marine and Petroleum Geology, v. 25, no. 9, p. 819-829, https://doi.org/10.1016/j.marpetgeo.2008.02.007.","productDescription":"11 p.","startPage":"819","endPage":"829","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":476715,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://hdl.handle.net/1912/2615","text":"External Repository"},{"id":239530,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Gulf of Mexico","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -90,\n              27\n            ],\n            [\n              -89,\n              27\n            ],\n            [\n              -89,\n              28\n            ],\n            [\n              -90,\n              28\n            ],\n            [\n              -90,\n             27\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"25","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b878be4b08c986b31653f","contributors":{"authors":[{"text":"Ruppel, C.","contributorId":82050,"corporation":false,"usgs":true,"family":"Ruppel","given":"C.","email":"","affiliations":[],"preferred":false,"id":428016,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Boswell, R.","contributorId":35121,"corporation":false,"usgs":true,"family":"Boswell","given":"R.","affiliations":[],"preferred":false,"id":428014,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Jones, E.","contributorId":66049,"corporation":false,"usgs":true,"family":"Jones","given":"E.","affiliations":[],"preferred":false,"id":428015,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These analyses are intended to help describe geochemical processes active in the aquifers and the source and release mechanism of arsenic in sediments for the Meghna Floodplain aquifer. The elevated Cl- and higher proportions of Na+ relative to Ca2+, Mg2+, and K+ in groundwater suggest the influence by a source of Na+ and Cl-. Use of chemical fertilizers may cause higher concentrations of NH 4+ and PO 43- in shallow well samples. In general, most ions are positively correlated with Cl-, with Na+ showing an especially strong correlation with Cl-, indicating that these ions are derived from the same source of saline waters. The relationship between Cl-/HCO 3- ratios and Cl- also shows mixing of fresh groundwater and seawater. Concentrations of dissolved HCO 3- reflect the degree of water-rock interaction in groundwater systems and integrated microbial degradation of organic matter. Mn and Fe-oxyhydroxides are prominent in the clayey subsurface sediment and well known to be strong adsorbents of heavy metals including arsenic. All five shallow well samples had high arsenic concentration that exceeded WHO recommended limit for drinking water. Very low concentrations of SO 42- and NO 3- and high concentrations of dissolved Fe and PO 43- and NH 4+ ions support the reducing condition of subsurface aquifer. Arsenic concentrations demonstrate negative co-relation with the concentrations of SO 42- and NO 3- but correlate weakly with Mo, Fe concentrations and positively with those of P, PO 43- and NH 4+ ions. ?? 2007 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s00254-007-0907-3","issn":"09430105","usgsCitation":"Zahid, A., Hassan, M., Balke, K., Flegr, M., and Clark, D., 2008, Groundwater chemistry and occurrence of arsenic in the Meghna floodplain aquifer, southeastern Bangladesh: Environmental Geology, v. 54, no. 6, p. 1247-1260, https://doi.org/10.1007/s00254-007-0907-3.","startPage":"1247","endPage":"1260","numberOfPages":"14","costCenters":[],"links":[{"id":214619,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00254-007-0907-3"},{"id":242359,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"54","issue":"6","noUsgsAuthors":false,"publicationDate":"2007-07-13","publicationStatus":"PW","scienceBaseUri":"505a2d95e4b0c8380cd5bf39","contributors":{"authors":[{"text":"Zahid, A.","contributorId":56875,"corporation":false,"usgs":true,"family":"Zahid","given":"A.","email":"","affiliations":[],"preferred":false,"id":434136,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hassan, M.Q.","contributorId":71783,"corporation":false,"usgs":true,"family":"Hassan","given":"M.Q.","email":"","affiliations":[],"preferred":false,"id":434138,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Balke, K.-D.","contributorId":7927,"corporation":false,"usgs":true,"family":"Balke","given":"K.-D.","email":"","affiliations":[],"preferred":false,"id":434134,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Flegr, M.","contributorId":61660,"corporation":false,"usgs":true,"family":"Flegr","given":"M.","email":"","affiliations":[],"preferred":false,"id":434137,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Clark, D.W.","contributorId":22765,"corporation":false,"usgs":true,"family":"Clark","given":"D.W.","email":"","affiliations":[],"preferred":false,"id":434135,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

In 1967, a landslide-dam-break flood in a pristine reach of the Elwha River valley filled the former channel and diverted the river. The reach is a reference site for restoration following the planned removal of dams on the river. We identified five surfaces on the 25 ha debris fan deposited by the flood. Based on tree ages and historic air photos, three of the surfaces formed in 1967, while two formed later. The surfaces varied in substrate (silt and sand, to boulders), and height above the river channel. Tree mortality resulted from tree removal and burial by sediment, the latter leaving snags and some surviving trees. Tree species composition was generally consistent within each surface. Dominant species included red alder (Alnus rubra) and Sitka willow (Salix sitchensis), alone or in combination, a combination of Douglas-fir (Pseudotsuga menziesii) and black cottonwood (Populus balsamifera ssp. trichocarpa), or a combination of alder and Cottonwood. There were significant differences between surfaces in stem density, basal area, and rate of basal area growth. The large degree of heterogeneity in forest structure, composition, and productivity within a relatively small floodplain feature is in part due to spatial variability in the intensity of a single disturbance event, and in part due to the occurrence of subsequent, smaller events. To recreate natural diversity of riparian forests may require mimicking the variety of physical and biotic habitats that a single, complex disturbance event may create.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Northwest Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"0029344X","usgsCitation":"Acker, S., Beechie, T., and Shafroth, P., 2008, Effects of a natural dam-break flood on geomorphology and vegetation on the Elwha River, Washington, U.S.A.: Northwest Science, v. 82, no.

The availability of energy and essential nutrients to top predators such as seabirds that rely on resources near the water's surface will be affected by changes in pelagic prey abundance. Here, we present results from analysis of a 25-year data set documenting dietary change in a predatory seabird from the Laurentian Great Lakes. We reveal significant declines in trophic position and alterations in energy and nutrient flow over time. Temporal changes in seabird diet tracked decreases in pelagic prey fish abundance. As pelagic prey abundance declined, birds consumed less aquatic prey and more terrestrial food. This pattern was consistent across all five large lake ecosystems. Declines in prey fish abundance may have primarily been the result of predation by stocked piscivorous fishes, but other lake-specific factors were likely also important. Natural resource management activities can have unintended consequences for nontarget ecosystem components. Reductions in pelagic prey abundance have reduced the capacity of the Great Lakes to support the energetic requirements of surface-feeding seabirds. In an environment characterized by increasingly limited pelagic fish resources, they are being offered a Hobsonian choice: switch to less nutritious terrestrial prey or go hungry. ?? 2008 by the Ecological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/07-1603.1","issn":"00129658","usgsCitation":"Hebert, C., Weseloh, D., Idrissi, A., Arts, M., O'Gorman, R., Gorman, O.T., Locke, B., Madenjian, C., and Roseman, E., 2008, Restoring piscivorous fish populations in the Laurentian Great Lakes causes seabird dietary change: Ecology, v. 89, no. 4, p. 891-897, https://doi.org/10.1890/07-1603.1.","startPage":"891","endPage":"897","numberOfPages":"7","costCenters":[],"links":[{"id":214756,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/07-1603.1"},{"id":242506,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"89","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aaae5e4b0c8380cd865b2","contributors":{"authors":[{"text":"Hebert, C.E.","contributorId":44369,"corporation":false,"usgs":true,"family":"Hebert","given":"C.E.","email":"","affiliations":[],"preferred":false,"id":434946,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Weseloh, D.V.C.","contributorId":35703,"corporation":false,"usgs":true,"family":"Weseloh","given":"D.V.C.","email":"","affiliations":[],"preferred":false,"id":434945,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Idrissi, A.","contributorId":46783,"corporation":false,"usgs":true,"family":"Idrissi","given":"A.","affiliations":[],"preferred":false,"id":434947,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Arts, M.T.","contributorId":12685,"corporation":false,"usgs":true,"family":"Arts","given":"M.T.","email":"","affiliations":[],"preferred":false,"id":434944,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"O'Gorman, R.","contributorId":48896,"corporation":false,"usgs":true,"family":"O'Gorman","given":"R.","affiliations":[],"preferred":false,"id":434948,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Gorman, O.

Extensive wetlands in the southeastern United States have many ecosystem attributes ideal for promoting high MeHg production rates; however, relatively few mercury cycling studies have been conducted in these environments. We conducted a landscape scale study examining Hg cycling in coastal Louisiana (USA) including four field trips conducted between August 2003 and May 2005. Sites were chosen to represent different ecosystem types, including: a large shallow eutrophic estuarine lake (Lake Pontchartrain), three rivers draining into the lake, a cypress-tupelo dominated freshwater swamp, and six emergent marshes ranging from a freshwater marsh dominated by<span>&nbsp;</span><i>Panicum hemitomon</i><span>&nbsp;</span>to a<span>&nbsp;</span><i>Spartina alterniflora</i><span>&nbsp;</span>dominated salt marsh close to the Gulf of Mexico.

Concentrations of THg and MeHg in filtered surface water were positively correlated with the highly reactive, aromatic (hydrophobic organic acid) fraction of dissolved organic carbon (DOC). These results suggest that DOC plays an important role in promoting the mobility, transport and bioavailability of inorganic Hg in these environments.

We compared estimates of breeding pairs of waterbirds, in colonies across southern Louisiana, USA, made from the ground, fixed-wing aircraft, and a helicopter. We used a marked-subsample method for ground-counting colonies to obtain estimates of error and visibility bias. We made comparisons over 2 sampling periods: 1) surveys conducted on the same colonies using all 3 methods during 3-11 May 2005 and 2) an expanded fixed-wing and ground-survey comparison conducted over 4 periods (May and Jun, 2004-2005). Estimates from fixed-wing aircraft were approximately 65% higher than those from ground counts for overall estimated number of breeding pairs and for both dark and white-plumaged species. The coefficient of determination between estimates based on ground and fixed-wing aircraft was ???0.40 for most species, and based on the assumption that estimates from the ground were closer to the true count, fixed-wing aerial surveys appeared to overestimate numbers of nesting birds of some species; this bias often increased with the size of the colony. Unlike estimates from fixed-wing aircraft, numbers of nesting pairs made from ground and helicopter surveys were very similar for all species we observed. Ground counts by one observer resulted in underestimated number of breeding pairs by 20% on average. The marked-subsample method provided an estimate of the number of missed nests as well as an estimate of precision. These estimates represent a major advantage of marked-subsample ground counts over aerial methods; however, ground counts are difficult in large or remote colonies. Helicopter surveys and ground counts provide less biased, more precise estimates of breeding pairs than do surveys made from fixed-wing aircraft. We recommend managers employ ground counts using double observers for surveying waterbird colonies when feasible. Fixed-wing aerial surveys may be suitable to determine colony activity and composition of common waterbird species. The most appropriate combination of survey approaches will be based on the need for precise and unbiased estimates, balanced with financial and logistical constraints.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/2006-391","issn":"0022541X","usgsCitation":"Green, M., Luent, M., Michot, T., Jeske, C., and Leberg, P., 2008, Comparison and assessment of aerial and ground estimates of waterbird colonies: Journal of Wildlife Management, v. 72, no. 3, p. 697-706, https://doi.org/10.2193/2006-391.","startPage":"697","endPage":"706","numberOfPages":"10","costCenters":[],"links":[{"id":214714,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2006-391"},{"id":242463,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"72","issue":"3","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"5059f83ce4b0c8380cd4cf74","contributors":{"authors":[{"text":"Green, M.C.","contributorId":37974,"corporation":false,"usgs":true,"family":"Green","given":"M.C.","email":"","affiliations":[],"preferred":false,"id":434161,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Luent, M.C.","contributorId":107953,"corporation":false,"usgs":true,"family":"Luent","given":"M.C.","affiliations":[],"preferred":false,"id":434164,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Michot, T.C. 0000-0002-7044-987X","orcid":"https://orcid.org/0000-0002-7044-987X","contributorId":43426,"corporation":false,"usgs":true,"family":"Michot","given":"T.C.","affiliations":[],"preferred":false,"id":434163,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jeske, C.W.","contributorId":35557,"corporation":false,"usgs":true,"family":"Jeske","given":"C.W.","email":"","affiliations":[],"preferred":false,"id":434160,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Leberg, P.L.","contributorId":42048,"corporation":false,"usgs":true,"family":"Leberg","given":"P.L.","affiliations":[],"preferred":false,"id":434162,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Unfortunately, management actions to address one may create or exacerbate the other. A consistent decision process would include a systematic analysis of when and where intentional use or removal of barriers is the most appropriate action. We developed a Bayesian belief network as a tool for such analyses. We focused on native westslope cutthroat trout (Oncorhynchus clarkii lewisi) and nonnative brook trout (Salvelinus fontinalis) and considered the environmental factors influencing both species, their potential interactions, and the effects of isolation on the persistence of local cutthroat trout populations. The trade-offs between isolation and invasion were strongly influenced by size and habitat quality of the stream network to be isolated and existing demographic linkages within and among populations. An application of the model in several sites in western Montana (USA) showed the process could help clarify management objectives and options and prioritize conservation actions among streams. The approach can also facilitate communication among parties concerned with native salmonids, nonnative fish invasions, barriers and intentional isolation, and management of the associated habitats and populations. ?? 2008 NRC.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Fisheries and Aquatic Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/F07-184","issn":"0706652X","usgsCitation":"Peterson, D., Rieman, B., Dunham, J., Fausch, K., and Young, M., 2008, Analysis of trade-offs between threats of invasion by nonnative brook trout (Salvelinus fontinalis) and intentional isolation for native westslope cutthroat trout (Oncorhynchus clarkii lewisi): Canadian Journal of Fisheries and Aquatic Sciences, v. 65, no. 4, p. 557-573, https://doi.org/10.1139/F07-184.","startPage":"557","endPage":"573","numberOfPages":"17","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":242609,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214856,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/F07-184"}],"volume":"65","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059eb44e4b0c8380cd48d0e","contributors":{"authors":[{"text":"Peterson, D.P.","contributorId":30061,"corporation":false,"usgs":true,"family":"Peterson","given":"D.P.","email":"","affiliations":[],"preferred":false,"id":434799,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rieman, B.E.","contributorId":67283,"corporation":false,"usgs":true,"family":"Rieman","given":"B.E.","email":"","affiliations":[],"preferred":false,"id":434801,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dunham, J.

Discriminant analysis indicated that dominant taxa at riffles and snags differed; Hydropsychid caddisflies (Hydropsyche betteni and Cheumatopsyche spp.) and elmid beetles (Optioservus spp. and Stenemlis spp.) typified riffles, whereas isopods (Asellus intermedius) and amphipods (Hyalella azteca and Gammarus pseudolimnaeus) predominated in snags. Analysis of covariance indicated that samples from snag and riffle habitats differed significantly in their response to the urbanization gradient for the Hilsenhoff biotic index (BI), Shannon's diversity index, and percent of filterers, shredders, and pollution intolerant Ephemeroptera, Plecoptera, and Trichoptera (EPT) at each stream site (p ??? 0.10). These differences suggest that although macroinvertebrate assemblages present in either habitat type are sensitive to detecting the effects of urbanization, metrics derived from different habitats should not be intermixed when assessing stream quality through biomonitoring. This can be a limitation to resource managers who wish to compare water quality among streams where the same habitat type is not available at all stream locations, or where a specific habitat type (i.e., a riffle) is required to determine a metric value (i.e., BI). To account for differences in stream quality at sites lacking riffle habitat, snag-derived metric values can be adjusted based on those obtained from riffles that have been exposed to the same level of urbanization. Comparison of nonlinear regression equations that related stream quality metric values from the two habitat types to percent watershed urbanization indicated that snag habitats had on average 30.2 fewer percent EPT individuals, a lower diversity index value than riffles, and a BI value of 0.29 greater than riffles. ?? 2008 American Water Resources Association.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the American Water Resources Association","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1752-1688.2008.00197.x","issn":"1093474X","usgsCitation":"Stepenuck, K., Crunkilton, R., Bozek, M.A., and Wang, L., 2008, Comparison of macroinvertebrate-derived stream quality metrics between snag and riffle habitats: Journal of the American Water Resources Association, v. 44, no. 3, p. 670-678, https://doi.org/10.1111/j.1752-1688.2008.00197.x.","startPage":"670","endPage":"678","numberOfPages":"9","costCenters":[],"links":[{"id":476778,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/2027.42/74406>","text":"External Repository"},{"id":214995,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1752-1688.2008.00197.x"},{"id":242759,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"44","issue":"3","noUsgsAuthors":false,"publicationDate":"2008-05-16","publicationStatus":"PW","scienceBaseUri":"5059f870e4b0c8380cd4d0e2","contributors":{"authors":[{"text":"Stepenuck, K.F.","contributorId":72975,"corporation":false,"usgs":true,"family":"Stepenuck","given":"K.F.","affiliations":[],"preferred":false,"id":434094,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Crunkilton, R.L.","contributorId":58048,"corporation":false,"usgs":true,"family":"Crunkilton","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":434093,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bozek, Michael A.","contributorId":51030,"corporation":false,"usgs":true,"family":"Bozek","given":"Michael","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":434092,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Wang, L.","contributorId":76904,"corporation":false,"usgs":true,"family":"Wang","given":"L.","email":"","affiliations":[],"preferred":false,"id":434095,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Four small-bodied riverine species were examined in our comparison of the two methods. Mean GSI was significantly different between all histological stages for suckermouth minnow and red shiner. Mean GSI was significantly different between most stages for slenderhead darter; whereas stages 3 and 6 were not significantly different, the time period when these stages are present would allow fisheries biologists to distinguish between the two stages. Mean GSI was not significantly different for many histological stages in stonecat. Difficulties in distinguishing between histological stages and GSI associated with stonecat illustrate potential problems obtaining appropriate sample sizes from species that move to alternative habitats to spawn. We suggest that GSI would be a useful tool in identifying mature ovaries in many small-bodied, multiple-spawning fishes. This information could be combined with data from histology during mature periods to pinpoint specific spawning events. ?? 2007 Blackwell Munksgaard.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology of Freshwater Fish","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1600-0633.2007.00256.x","issn":"09066691","usgsCitation":"Brewer, S., Rabeni, C., and Papoulias, D., 2008, Comparing histology and gonadosomatic index for determining spawning condition of small-bodied riverine fishes: Ecology of Freshwater Fish, v. 17, no. 1, p. 54-58, https://doi.org/10.1111/j.1600-0633.2007.00256.x.","startPage":"54","endPage":"58","numberOfPages":"5","costCenters":[],"links":[{"id":214705,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1600-0633.2007.00256.x"},{"id":242453,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"17","issue":"1","noUsgsAuthors":false,"publicationDate":"2007-06-20","publicationStatus":"PW","scienceBaseUri":"5059f834e4b0c8380cd4cf39","contributors":{"authors":[{"text":"Brewer, S.K.","contributorId":34284,"corporation":false,"usgs":true,"family":"Brewer","given":"S.K.","email":"","affiliations":[],"preferred":false,"id":433575,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rabeni, C.F.","contributorId":67823,"corporation":false,"usgs":true,"family":"Rabeni","given":"C.F.","affiliations":[],"preferred":false,"id":433577,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Papoulias, D.

In this simulation, AVIRIS images were converted to radiance, then spectrally resampled to six wavelength bands commonly used for terrestrial observation. Preliminary results indicate that differences between the simulations can be attributed to variations in surface reflectance within spectral bands, and suggest influences due to water vapor absorption. Radiance simulated from the spectrally narrow Moderate Resolution Imaging Spectroradiometer (MODIS) relative spectral responses (RSR) was generally higher than that using the broader Enhanced Thematic Mapper Plus (ETM+) RSRs over most targets encountered over the test area. This is consistent with many MODIS bands being biased toward shorter wavelengths compared to corresponding ETM+ bands when viewing targets whose radiance decreases with wavelength. In some cases the higher radiance values appeared to occur where the MODIS RSR is better situated over peak reflected wavelengths. Simulation differences between MODIS &amp; ETM+ bands in the near-infrared indicated higher MODIS radiance values that suggest the influence of water vapor absorption at 820 nanometers.

The elemental composition of about 300 molecules was identified. Those in the HPO fraction (14C age of 5100 year) are very similar to much younger freshwater fulvic acids, but less aromatic and more oxygenated molecules are more frequent. This trend continues toward the HPI fraction and may indicate biotic and abiotic aging processes that this material experienced since its primary production thousands of years ago. In the HPI fraction series of nitrogenous molecules containing one, two, or three nitrogens were identified by FTICR-MS. Product ion spectra of the nitrogenous molecules suggest that the nitrogen atoms in these molecules are included in the (alicyclic) backbone of these molecules, possibly in reduced form. These mass spectrometric data suggest that a large set of stable fulvic acids is ubiquitous in all aquatic compartments. Although sources may differ, their actual composition and structure appears to be quite similar and largely independent from their source, because they are the remainder of intensive oxidative degradation processes. ?? 2008 American Chemical Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es7021413","issn":"0013936X","usgsCitation":"Reemtsma, T., These, A., Linscheid, M., Leenheer, J., and Spitzy, A., 2008, Molecular and structural characterization of dissolved organic matter from the deep ocean by FTICR-MS, including hydrophilic nitrogenous organic molecules: Environmental Science & Technology, v. 42, no. 5, p. 1430-1437, https://doi.org/10.1021/es7021413.","startPage":"1430","endPage":"1437","numberOfPages":"8","costCenters":[],"links":[{"id":214909,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es7021413"},{"id":242669,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"42","issue":"5","noUsgsAuthors":false,"publicationDate":"2008-02-01","publicationStatus":"PW","scienceBaseUri":"505a5cf7e4b0c8380cd7007f","contributors":{"authors":[{"text":"Reemtsma, T.","contributorId":35608,"corporation":false,"usgs":true,"family":"Reemtsma","given":"T.","email":"","affiliations":[],"preferred":false,"id":434998,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"These, A.","contributorId":89025,"corporation":false,"usgs":true,"family":"These","given":"A.","email":"","affiliations":[],"preferred":false,"id":435000,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Linscheid, M.","contributorId":101531,"corporation":false,"usgs":true,"family":"Linscheid","given":"M.","email":"","affiliations":[],"preferred":false,"id":435001,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Leenheer, J.","contributorId":71714,"corporation":false,"usgs":true,"family":"Leenheer","given":"J.","affiliations":[],"preferred":false,"id":434999,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Spitzy, A.","contributorId":33593,"corporation":false,"usgs":true,"family":"Spitzy","given":"A.","email":"","affiliations":[],"preferred":false,"id":434997,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Foraging theory suggests that predators will modify their behaviors, including movements, to optimize net energy intake when faced with variation in prey attributes or abundance. While many studies have documented changes in movement patterns of animals in response to temporal changes in food, very few have contrasted movements of a single predator species naturally occurring in dramatically different prey landscapes. We documented variation in the winter movements, foraging range size, site fidelity, and distribution patterns of a molluscivorous sea duck, the surf scoter (Melanitta perspicillata), in two areas of coastal British Columbia with very different shellfish prey features. Baynes Sound has extensive tidal flats with abundant clams, which are high-quality and temporally stable prey for scoters. Malaspina Inlet is a rocky fjord-like inlet where scoters consume mussels that are superabundant and easily accessible in some patches but are heavily depleted over the course of winter. We used radio telemetry to track surf scoter movements in both areas and found that in the clam habitats of Baynes Sound, surf scoters exhibited limited movement, small winter ranges, strong foraging site fidelity, and very consistent distribution patterns. By contrast, in mussel habitats in the Malaspina Inlet, surf scoters displayed more movement, larger ranges, little fidelity to specific foraging sites, and more variable distribution patterns. We conclude that features associated with the different prey types, particularly the higher depletion rates of mussels, strongly influenced seasonal space use patterns. These findings are consistent with foraging theory and confirm that predator behavior, specifically movements, is environmentally mediated. ?? 2008 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Oecologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s00442-007-0947-0","issn":"00298549","usgsCitation":"Kirk, M., Esler, D., Iverson, S.A., and Boyd, W.S., 2008, Movements of wintering surf scoters: Predator responses to different prey landscapes: Oecologia, v. 155, no. 4, p. 859-867, https://doi.org/10.1007/s00442-007-0947-0.","startPage":"859","endPage":"867","numberOfPages":"9","costCenters":[],"links":[{"id":239810,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":212339,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00442-007-0947-0"}],"volume":"155","issue":"4","noUsgsAuthors":false,"publicationDate":"2008-01-22","publicationStatus":"PW","scienceBaseUri":"505a5f74e4b0c8380cd70f7a","contributors":{"authors":[{"text":"Kirk, M.","contributorId":30039,"corporation":false,"usgs":true,"family":"Kirk","given":"M.","email":"","affiliations":[],"preferred":false,"id":433090,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Esler, Daniel 0000-0001-5501-4555 desler@usgs.gov","orcid":"https://orcid.org/0000-0001-5501-4555","contributorId":5465,"corporation":false,"usgs":true,"family":"Esler","given":"Daniel","email":"desler@usgs.gov","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":12437,"text":"Simon Fraser University, Centre for Wildlife Ecology","active":true,"usgs":false},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":433088,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Iverson, S.
