Fish and Wildlife Disease

The United States is undergoing ecological change that is increasing the interface between wildlife, humans, and disease. Such changes are resulting in unpredictable shifts in the balances of disease cycles in natural hosts and humans, with consequences to many imperiled species. In addition to population declines, the loss of wildlife from disease contributes to a corresponding decline in ecosystem services that benefit human health and economies. TSH scientists collaborate with researchers and resource managers around the world to gain better scientific understanding of the ecological factors involved in the transmission and epidemiology of infectious diseases in wildlife, as well as contributing to the development of tools and techniques to help understand and manage disease in wildlife populations.

Effects of Soil and Colony Age on Flea Densities

Abundance of fleas is thought to drive rates of plague transmission in the wild. In the complex process of plague maintenance and transmission, fleas as vectors are a potentially weak link in the system that can be exploited. To date, exploiting this link has provided the only stand-alone tools that are operationally effective for managing plague in the black-footed ferret/prairie dog community (i...

External Microbiota of Bats as Potential Bio-control Against Wildlife Diseases

White-nose syndrome (WNS) and/or Pseudogymnoascus destructans (P.d.), the causal agent, has spread westward across 26 states and 5 provinces within the eastern United States and Canada, respectively, over a short period of time. Since its discovery there has been a search to stop the spread of this disease that has killed millions of hibernating bats in its wake. Recent collaborative work by FORT...

White-Nose Syndrome Threatens the Survival of Hibernating Bats in North America

During the winter of 2006–2007, an affliction of unknown origin dubbed “white-nose syndrome” (WNS) began devastating colonies of hibernating bats in a small area around Albany, New York. Colonies of hibernating bats were reduced 80–97 percent at the affected caves and mines that were surveyed. Since then, white-nose syndrome or its causative agent have consistently spread more than 2,000...

WNS Data Management Coordination

White-nose syndrome (WNS) is a disease responsible for unprecedented mortality in hibernating bats in the northeastern U.S. This previously unrecognized disease has spread very rapidly since its discovery in January 2007 and poses a considerable threat to hibernating bats throughout North America.

Transmission of plague by small mammals at Badlands National Park

Plague was first detected in the southwest corner of Badlands National Park (BADL), and spread northeastward, reaching the northeast corner in 2011. Multiple prairie dog colonies in BADL and Conata Basin have had population collapses from plague since its arrival in the park. Plague is now common throughout BADL (NPS and USFS, unpublished data), and threatens efforts to preserve and manage the...

Surveillance for the Presence of White-Nose Syndrome in the Bat Community at El Malpais National Monument, New Mexico

In 1999 and 2000, FORT conducted a survey of bats at El Malpais National Monument and adjacent lands. During this study, several species of bats were documented, including some that are known to use caves or lava-tube formations as roosts. In the winter of 2006–2007, the fungus-caused disease known as “white-nose syndrome” (WNS) began devastating populations of hibernating bat species that use...
