soundwaves.usgs.gov — U.S. Geological Survey (USGS)'s Western Region held an internal USGS workshop on Sea-Level-Rise Impacts on November 6-7, 2007, in Menlo Park, California. The meeting was attended by 30 scientists from four USGS disciplines (geology, geography, biology, and water) and 13 different science centers in the Western Region. In part a follow-up to the More...

wfrc.usgs.gov — This U.S./Russian collaboration will investigate genetics and life histories of Kamchatka Peninsula rainbow trout and steelhead (O. mykiss), and Dolly Varden, white-spotted, and arctic char (S. malma, S. leucomaensis, and S. alpinus, respectively). Both anadromous and resident forms of these generally occur in Kamchatka rivers that are free from More...

wfrc.usgs.gov — Since 1994, scientists from the Anadromous Fish Ecology Team have been assisting the U.S. Army Corps of Engineers (USACE) in evaluating the migration behavior and passage of juvenile salmon and steelhead through Lower Granite Reservoir and Dam on the Snake River, WA. The goal of this study is to identify the behavior of individual juvenile salmon More...

wfrc.usgs.gov — The Arctic charr (Salvelinus alpinus) in the northern most latitudes migrate to the ocean in the spring to feed and grow. This results in accumulation of polychlorinated biphenyls (PCB) in their visceral fat. During the winter, the charr reside in freshwater lakes and do not feed. They do mobilize lipids from adipose tissue for energy, which More...

wfrc.usgs.gov — Threatened and endangered salmonids in the Pacific Northwest often use backwaters and wetlands as they migrate toward the ocean, however our understanding of the role of wetlands to juvenile salmonids is limited. The major Objective of this study was to determine whether juvenile steelhead were being tapped on the wetland during spring, and More...

fisc.er.usgs.gov — This website provides access to the list of imperiled freshwater and diadromous fishes of North America as determined by the 2008 American Fisheries Society (AFS) Endangered Species Committee (ESC) on Fishes. At this website, one can view lists of imperiled fishes by freshwater ecoregion, by state or province boundary, and plot distributions of More...

wfrc.usgs.gov — Fall chinook salmon (Oncorhynchus tshawytscha) in the Snake River are currently listed as threatened under the Endangered Species Act (ESA). Because fall chinook salmon migrate seaward during the summer when flows are low and water temperatures are high, their survival rate is lower. The goal of this study is to more clearly identify the More...

www.nbii.gov — Natural resource managers face complex decisions that require a clear understanding of the status of wildlife populations and their habitats. Monitoring is key to making effective management decisions and evaluating the outcomes of those decisions. The goal of NRMP is to improve the accessibility of monitoring efforts to resource managers to aid More...

www.fort.usgs.gov — Natural Resource Monitoring Partnership (NRMP) is a collaborative effort by the natural resource management community to improve monitoring efforts in order to support effective evaluation and decision-making by sharing information on monitoring projects and protocols. The Natural Resource Monitoring Partnership was built for easy access to More...

wfrc.usgs.gov — As anadromous juvenile salmonids migrate from freshwater rearing habitats to the ocean, they are vulnerable to a host of factors that affect their survival. Direct effects associated with dam passage (e.g., instantaneous mortality, injury, loss of equilibrium, etc.) and indirect effects (e.g., predation, disease, and physiological stress) More...
