In North America, the flea transmitted plague bacterium (Yersinia pestis) has colonized and altered native animal communities and ecosystems for more than a century. Many species have suffered adverse consequences from plague, perhaps none more than the endangered black-footed ferret. Plague has established within the ranges of all North American prairie dog species, which collectively serve as...

White-Nose Syndrome (WNS) is a devastating disease that threatens the survival of hibernating bats in North America. Since first documented in the winter of 2005/2006, WNS has spread from a very small area of New York across at least two thousand kilometers and half or more of states and provinces in the U.S. and Canada.

White-Nose Syndrome (WNS) is a devastating disease that threatens the survival of hibernating bats in North America. Since first documented in the winter of 2005/2006, WNS has spread from a very small area of New York across at least two thousand kilometers in half or more of states and provinces in the U.S. and Canada. Over five million bats are estimated to have died during the past decade from...

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...

A multi-agency effort assesses the health of manatees and provides baseline information on their health, reproductive status, and nutritional condition.

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...

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...

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.

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...

Bats are the only flying mammals that are active mostly at night and occur on all continents except Antarctica. Bats are ecologically diverse, with a range of species that specialize in feeding on fruit, nectar, blood, fish, small mammals, and insects. However, of the more than 1,100 known species of bats on Earth, the majority specialize in feeding on insects. In the United States for example, of...

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...

A severe disease - tentatively named stony coral tissue loss disease - is rapidly killing corals in the U.S. Virgin Islands. Scientists from the U.S. Geological Survey, the University of Puerto Rico, and the National Park Service are working together to better under the disease and determine if the disease affecting corals in the USVI is the same one that has been killing corals in Florida since...
