Wildlife Disease Surveillance

Native freshwater mussels play a critical role in aquatic environments and are considered “ecosystem engineers” and indicators of water quality by constantly filtering water. Populations of native freshwater mussels have declined in recent years, and this decline has been attributed to factors such as habitat degradation, pollution, and invasive species, among others. The importance of these...

Assessing Impacts of Emerging and Established Diseases to Aquatic Ecosystems The decline of native freshwater mussels has the potential to devastate aquatic communities. Although factors such as habitat degradation, pollution, and invasive species have been linked to this decline, these potential causes cannot fully explain the large-scale mussel die-offs that have occurred in the past 20 years...

Bat Research Research collaboration: Brian Reichert (FORT), Wayne Thogmartin (UMESC), Winifred Frick (Bat Conservation International), Tina Cheng (Bat Conservation International) The northern long-eared bat ( Myotis septentrionalis) was listed as Threatened on the Endangered Species Act in 2014 due to rapid declines in numbers of observed hibernating bats at winter roosting sites after the arrival...

Bat Research Research collaboration: Brian Reichert (FORT), Anne Ballmann (NWHC), Jeremy Coleman (USFWS), Paul Cryan (FORT), Wayne Thogmartin (UMESC), and Katherine Irvine (NOROCK) White-nose syndrome is caused by the fungal pathogen Pseudogymnoascus destructans (Pd), which has decimated hibernating bat populations across North America since it emerged 10 years ago in New York. While diagnostic...

Bat Research Research collaboration: Winifred Frick (Bat Conservation International), Brian Reichert (FORT), Theodore Weller (US Forest Service), Wayne Thogmartin (UMESC) and the North American Bat Colony Count Consortium We quantify vulnerability of bat species in North America to target and prioritize management actions toward species and habitats that are most at risk from impacts from White...

The USGS National Wildlife Health Center (NWHC) provides the following index of wildlife disease information resources as a starting point to learn about selected wildlife diseases.

Title of Study Plan: Residual toxicity testing and chemical characterization of ballast water following treatment with NaOH, sparging with scrubbed marine diesel engine exhaust, and aeration

The USGS National Wildlife Health Center (NWHC) provides quantitative support and technical assistance to state and federal wildlife managers and partners to better understand or predict the impact of disease on wildlife populations.

To provide the next generation of wildlife disease tools, that can move past detection and documentation and towards solutions for wildlife disease problems, the National Wildlife Health Center (NWHC) is developing a suite of new or adapted technology. Primarily, these technologies focus on three areas of improvement in the realm of wildlife disease: prediction and prevention, surveillance for...

The USGS National Wildlife Health Center (NWHC) conducts laboratory investigations to determine the causes of wildlife mortality events, especially large-scale die-offs or those that are otherwise unusual.

The USGS National Wildlife Health Center (NWHC) assists State, Federal, and Tribal wildlife agencies nationwide with early detection of Pseudogymnoascus destructans ( Pd), and addresses specific research priorities identified by partners in conjunction with the White-Nose Syndrome National Plan.

Lyme disease is the most prevalent vector-borne disease in North America, with about 300,000 cases per year in the U.S. We are studying transmission of the spirochete that causes this disease among wild animals and the blacklegged tick vectors, to determine why Lyme disease is common in the northeast and northern Midwest but rare in the south, even though blacklegged ticks are present in all of...
