West Nile virus (avian) case definition for wildlife
Diagnostic laboratories receive carcasses and samples for diagnostic evaluation and pathogen/toxin detection. Case definitions bring clarity and consistency to the evaluation process. Their use within and between organizations allows more uniform reporting of diseases and etiologic agents. The intent of a case definition is to provide scientifically based criteria for determining (a) if an individ
Network connectivity contributes to native small-bodied fish assemblages in the upper Mississippi River system
Effective management and conservation of fishes requires understanding habitat use across multiple life stages while ensuring necessary habitats are both available and accessible. Tributary habitats may play an important role in recruitment and dispersal of fishes in anthropogenically modified rivers such as the Mississippi and Illinois Rivers of the Midwest U.S.A. Identifying source locations tha
Acute toxicity of the lampricide 4-nitro-3-(trifluoromethyl)phenol to the Mussel (Obovaria subrotunda), its host (Percina maculata), and a surrogate mussel species (Obovaria olivaria)
The risk of lampricide applications (such as 4-nitro-3-[trifluoromethyl]phenol [TFM]) to nontarget fauna continues to be a concern within the Great Lakes Fishery Commission Sea Lamprey Control Program, especially among imperiled aquatic species—such as native freshwater mussels. The Grand River (Ohio, USA) is routinely treated for larval sea lampreys (Petromyzon marinus), and this river contains p

Expanding Distribution of Chronic Wasting Disease
Chronic wasting disease (CWD) has been detected in 33 US states and five Canadian provinces in free-ranging cervids and/or commercial captive cervid facilities. CWD has been detected in free-ranging cervids in 33 states and four provinces and in captive cervid facilities in 19 states and three provinces.
Synthesis of sage-grouse genetic information to support conservation and land management actions
Sage-grouse, iconic birds of the American West, have experienced dramatic reductions and fragmentation of habitat, resulting in significant conservation concern. Genetic information can help inform priorities for protection and habitat restoration as well as strategies for translocations, but may be difficult for resource managers to find, interpret, and use in their decision making. In this work...
Polar Bear Research
Polar bears ( Ursus maritimus ) are one of 4 marine mammal species managed by the U.S. Department of Interior. The USGS Alaska Science Center leads long–term research on polar bears to inform local, state, national and international policy makers regarding conservation of the species and its habitat. Our studies, ongoing since 1985, are focused on population dynamics, health and energetics...
