3Density estimation using spatial capture-recapture analyses: Application to vaccination of prairie dogs against sylvatic plague
Prairie dogs are notoriously difficult to enumerate, with previously methods including visual counts, mark-resight, burrow counts, and catch per unit effort. Unlike those methods, spatial capture-recapture (SCR) analyses allow for formal estimation of density along with associated estimates of uncertainty, detection probability, and the size of the average area over which an individual was detecte
Glucocorticoid and glycemic responses to immune challenge in a viviparous snake afflicted with an emerging mycosis
Disease may be both a cause and consequence of stress, and physiological responses to infectious disease may involve stress coping mechanisms that have important fitness consequences. For example, glucocorticoid and glycemic responses may affect host fitness by altering resource allocation and use in hosts, and these responses may be affected by competing stressors. To better understand the factor
Bacteriological analysis of unionid hemolymph collected from freshwater mussel populations in the Pacific northwestern United States
Native freshwater mussel (Unionidae) mortality events have been occurring with increased frequency in recent decades, with few investigations into potential etiological agents. In the western United States, no surveys have been published regarding the bacteria associated with unionid mussels. Herein, we examine locations of known mussel mortality events in the Chehalis River (Washington), in the C

Expanding Distribution of Chronic Wasting Disease
Chronic wasting disease (CWD) has been detected in 35 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 35 states and four provinces and in captive cervid facilities in 21 states and three provinces.
Diagnostic Case Submission Guidelines
Standard submission criteria for federal, state, and tribal natural resource agency partners The National Wildlife Health Center (NWHC) conducts laboratory diagnostics to determine causes of wildlife morbidity and mortality events. The following guidelines are used to determine which cases we accept for diagnostic evaluation. NWHC only accepts submissions from, or in coordination with, federal...
Interagency coordination on coral health
The USGS National Wildlife Health Center (NWHC) supports coral health through participation in two interagency coordination bodies, the Florida Disturbance Advisory Committee, which is focused on joint management of the Florida Coral Reef Tract, and the U.S. Coral Reef Task Force, which is focused on joint management of reef resources within U.S. Territories in both the Caribbean and Pacific.
