Programs L2 Landing Page

USGS is the lead Federal agency for wildlife disease research and surveillance. Our wildlife health capabilities provide research, information, and technical assistance needed to manage wildlife through disease events. Congress and our partners rely on our science to make informed decisions about fish and wildlife disease policy, planning and management.

Hibernating little brown bat
July 5, 2017

Hot new imagery from temperature-sensing cameras suggests that bats who warm up from hibernation together throughout the winter may be better at surviving white nose syndrome, a disease caused by a cold-loving fungus ravaging insect-eating bat populations in the United States and Canada.

Sampling for aquatic invasive species in the Greater Yellowstone Area.

The Challenge: The genomic revolution is giving wildlife biologists new tools to assess the role of wildlife in spreading diseases that affect human populations.   Peptide arrays are a high throughput technology that gives unprecedented breadth and depth of information about the immune system.  We are using peptide arrays to assess the immune responses of Chesapeake Bay...

Mallard (Anarhynchos platus)
February 2, 2017

The Challenge: In December of 2014, a novel strain of highly pathogenic avian influenza (HPAI) caused an outbreak in poultry on the West coast of the United States. From there, the virus progressed steadily eastward, causing $3.3 billion in economic losses in addition to 50 million chickens or turkeys dying or being depopulated. While the primary mode of spread appears...

Male Ruddy duck
February 2, 2017

The Challenge: The susceptibility and pathogenesis of highly pathogenic avian influenza virus (HPAI) has not been characterized in numerous duck species, especially diving ducks (genera Melanitta, Aythya, and Oxyura), some of which migrate across the continental US. The few studies available (on Tufted duck, Aythya fuligula) suggest that they may shed high amounts of virus, but it is unclear...

The Challenge: Changes in aquatic ecosystems related to climate change phenomena or other anthropogenically based environmental stressors have significant impact on the dynamics of the host-pathogen-environment relationship, often with surprising results. Therefore, biosurveillance of the aquatic environment for pathogens of significance to aquatic and terrestrial wildlife...

Tracking migratory movements with satellite telemetry.
February 2, 2017

The Challenge: Following outbreaks of highly pathogenic avian influenza (HPAI) in Eurasia, many researchers have attempted to determine how this virus spreads across the landscape. Unfortunately, prior to this work, most studies on HPAI movements were based on virology data alone, and no information on host ecology. Beginning in 2007, USGS Patuxent Wildlife Research Center (PWRC) and...

Blacklegged Ticks are Lyme Disease Carriers
December 5, 2016

The Challenge: Lyme disease, which is caused by a tick-transmitted spirochete, is the most common vector-borne disease in North America, with about 300,000 cases each year. Most cases occur in the northeastern and north central U.S., with relatively few in the south, even though the vector tick is present in all of these regions. The purpose of this research is to...

Scientist collecting stream data
December 5, 2016

The Challenge: The DOI WaterSMART (Sustain and Manage America’s Resources for Tomorrow) initiative is developing data and tools to help water managers identify current and future water shortages, for humans and for freshwater ecosystems. Fishes, for example, can decline in diversity and abundance when streamflow becomes too low, for too long.  However, ecologists find that effects...

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 Timeline
October 14, 2016

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...

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...

Black Duck (Anas rubripes)
September 20, 2016

The Challenge: The health of the abundant waterfowl species of Chesapeake Bay has become a major concern due to the spread of Avian Influenza (AI) across North America and the role of waterfowl as a vector of AI. For decades, the health of the Bay’s waterfowl has been affected by the degradation of water quality and food supply due to industrial contaminants,agricultural...

Response Immune System
September 20, 2016

The Challenge: In an era when emerging infectious diseases are steadily increasing, human populations are exposed to virulent new pathogens.  Insight into the human system can be gained from understanding the variety of immune adaptations of wildlife species.  The vertebrate immune system is not static.  Rather, it involves in response to the environment....

little brown bat (Myotis lucifugus) with white-nose syndrome hibernating in a Virginia cave during late spring of 2016. Patches of the fungus that causes white-nose syndrome can be seen growing out of the skin (white areas) near the nose and across the folded wing skin of this bat.  Spherical drops of water condensation coat the bat's outer fur, a normal condition that illustrates the cold and humid air bats need to successfully hibernate.
