fresc.usgs.gov — The river otter (Lontra canadensis) is a top predator of most aquatic food chains. The goal of this study is to further evaluate the relationship among the contaminants and observed reproductive organ hypoplasia in young male river otters, their occurrence, and mode of action or mechanism that causes hypoplasia with a larger series of data from More...

www.umesc.usgs.gov — The moose population in northwestern Minnesota has been declining for over 25 years. The U.S. Fish and Wildlife Service has identified a need to determine whether the moose decline is a result of nutrition, parasites, disease, contaminants, or a combination of those factors. In an attempt to determine the cause of death for moose in northwestern More...

www.pwrc.usgs.gov — Written summaries of biological characteristics and contaminant exposure and effects data for 38 coastal and estuarine terrestrial vertebrates are available. Species were selected based on their previous use in contaminant monitoring, their status as valued natural resources, or as representatives of taxonomic groups. Characterizations were More...

www.absc.usgs.gov — An extensive and diverse array of studies were implemented concurrent with and for several years following the Exxon Valdez oil spill to determine the acute and chronic effects to sea otters. In part, this paper describes what activities relative to sea otters should take place prior to, during, and following another spill similar to the Exxon More...

www.pwrc.usgs.gov — Information about ecotoxicological exposure and its effects on terrestrial vertebrates residing in estuarine and coastal habitats like the Atlantic, Gulf and Pacific Coasts, Alaska and Hawaii, as well as the Great Lakes. These vertebrates include birds, mammals, amphibians and reptiles. The data is a compilation of results from computerized More...

pollinators.nbii.gov — The global declines in many kinds of pollinator species could potentially impact the global food supply, as many plants depend upon specific pollinators to reproduce. The Web site of the NBII Pollinators Project provides access to information about the biology, ecology, conservation status, and threats to native pollinators, pollinator-dependent More...
