Report Mortality Events and Submit Specimens
Instructions for reporting wildlife morbidity/mortality and submitting specimens to the USGS National Wildlife Health Center (NWHC).
Development of SARS-CoV-2 vaccine to support black-footed ferret conservation
The SARS-CoV-2 virus is known to infect and cause severe disease, such as respiratory distress and death, in mustelids, including farm-raised mink ( Mustela lutreola and Neovison vison ) and domestic ferrets ( M. putorius ). This raised concern that the virus may also pose a threat to endangered black-footed ferrets ( Mustela nigripes ) managed in captivity for breeding and recovery purposes.
Enhanced Capacity for Chronic Wasting Disease Research and Certified Diagnostics at the USGS National Wildlife Health Center
Chronic wasting disease (CWD) is a fatal disease that impacts populations of deer, elk, moose, and other cervid species caused by an infectious protein called a prion.
Quarterly Mortality Reports
The National Wildlife Health Center produces quarterly wildlife mortality reports, containing information about wildlife mortality events throughout the United States and on occasion across North America.
Mapping Chronic Wasting Disease Management: Identify Opportunities for Intervention
This research effort is an interagency partnership between U.S. Geological Survey and U.S. Fish and Wildlife Service to model the social-ecological system that encompasses chronic wasting disease management in the United States. Chronic wasting disease (CWD) is a fatal, neurologically degenerative disease that impacts many cervid species in North America (e.g., elk, moose, mule deer, and white...
Prevalence Rates of Snake Fungal Disease and Its Population-level Impacts in a Snake Assemblage in Southwest Louisiana
WARC researchers used visual encounter surveys to determine prevalence rates of snake fungal disease in south-central Louisiana.
Interaction of Environmental Stressors and Batrachochytrium dendrobatidis (Bd) Pathogen Loads on Survival of Green Frogs (Lithobates clamitans)
The U.S. Geological Survey Amphibian Research Monitoring Initiative (ARMI) is using a combination of swabbing, non-lethal tissue sampling, soil and water sampling, and collection of a variety of other environmental variables to determine the relationships between the prevalence and pathogen load of Bd infection and environmental stressors on green treefrog survival.
Assessing Impacts of Emerging and Established Diseases to Aquatic Ecosystems
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...
Investigation Into Mass Mussel Die-off Events
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...
Integrating colony counts with NABat acoustic data to reveal the true impacts of White-Nose Syndrome on northern long-eared bats
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...
Developing online integrated data visualization tools for WNS and NABat
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...
Quantifying vulnerability of bat species to White-nose Syndrome across North America
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...
