2002 | Publisher: USGS | Science Center: Great Lakes Science Center (GLSC, Ann Arbor) | Format: .PDF
www.glsc.usgs.gov — In 2002, scientists from the Great Lakes Science Center assessed the health of the populations of preyfish for the biennial State of the Lakes Ecosystem Conference (SOLEC) to provide information to policy makers on the status of the lakes and future needs. Preyfish population is one of the 80 indicators used by SOLEC to determine the health of the More...

www.umesc.usgs.gov — This report describes an electronic database containing 474 annotated citations that are relevant to fish passage through dams in large temperate floodplain rivers. The goal of this project was to survey the literature to help define the potential ecological consequences of restricted fish passage through dams in the Upper Mississippi River System More...

www.umesc.usgs.gov — Research at the Upper Midwest Environmental Center, which gathered detailed observations on tree swallow nesting success and contaminant concentrations in 1998-2000, to guide EPA and the U.S. Fish and Wildlife Service in effectively managing the risk of chemical contaminants to wildlife and the environment.
Publisher: USGS | Science Center: Northern Rocky Mountain Science Center (NRMSC, Bozeman) | Format: URL
nrmsc.usgs.gov — Northern Rocky Mountain Science Center has been monitoring, conducting research, and modeling ecosystem responses to climatic variability since 1991, first at Glacier National Park but eventually throughout the western U.S. in collaboration with other scientists. Coordination with scientists around the world have led to mountain research networks 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...

fresc.usgs.gov — The long-delayed Inland Lakes Fishery Inventory for Isle Royale was funded in FY95-97. This project will collect biological/physical/chemical samples as part of that project because such information is a logical component to a fishery survey. The objective of this study is to characterize the zooplankton assemblages in selected park lakes.

fl.biology.usgs.gov — The red shiner (Cyprinella lutrensis) is a hardy, widespread minnow native to the middle and southwestern United States and Mexico. Its native range encompasses the lowland tributaries of the Mississippi River and western Gulf slope drainages to the Rio Grande River. The red shiner peripherally occurs in the southeastern United States, inhabiting More...

www.umesc.usgs.gov — Eurasian Ruffe pose a threat to native fish because they(1) mature quickly, (2) have a high reproductive capacity, and (3) easily adapt to new environments. Ruffe were first detected in western Lake Superior in 1986. UMESC scientists are conducting research on various types of piscicides (chemicals that kill fish). They are attempting to develop More...

wfrc.usgs.gov — Mercury contamination from historic gold mining operations is widespread in many rivers, lakes, and reservoirs on the western slopes of the Sierra Nevada. A multidisciplinary investigation by USGS is attempting to better understand mercury dynamics and to identify hot spots within Camp Far West Reservoir in order to determine if remediation More...

tinyurl.com — Organochlorine pesticide and total polychlorinated biphenyl (PCB) concentrations were measured in largemouth bass from the Tombigbee River near a former DDT manufacturing facility at McIntosh, Alabama. Concentrations of DDT isomers in McIntosh bass remained unchanged from 1974 to 2004 and were four times greater than contemporary concentrations More...
