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...

fl.biology.usgs.gov — The African jewelfish (Hemichromis letourneuxi) has been established in canals surrounding the Miami area since the 1960s. With changes in water delivery to the park, the species has recently (2000) entered Everglades National Park and expanded its range westward through Big Cypress National Preserve. Simultaneously, African jewelfish from a 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...

fl.biology.usgs.gov — The Nile tilapia (Oreochromis niloticus) is commonly used in aquaculture worldwide. Feral populations exist in many regions where individuals escape culture and establish in natural habitats. In Mississippi, Nile tilapia are established in at least three distinct localities (fig. 1): the lower Pascagoula and Escatawpa river drainages, and a 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 — 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...
