3 Cool Ways USGS is Studying Bats in National Parks
USGS and international team identify the pathogen responsible for 2022 die-off of long-spined sea urchins across the Caribbean
USGS is the lead Federal agency for free-ranging wildlife disease research and surveillance. Our capabilities enhance the understanding of wildlife disease ecology and epidemiology as well as inform the development of decision-support and control tools. USGS wildlife disease experts provide technical assistance as needed to manage wildlife disease and conduct cause-of-death investigations.

A continental-scale study of acoustic phenology to improve population monitoring and inform management of hibernating bats
Bat Research Research collaboration: Winifred Frick (Bat Conservation International), Theodore Weller (U.S. Forest Service), Wayne Thogmartin (UMESC), Craig Willis (University of Winnipeg), and Brian Reichert (FORT) White-nose Syndrome (WNS) has caused severe declines in bat populations over the past 10 years and colony sizes at winter hibernacula have decreased on average by >90% for three...
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...
Modeling the response of cave hibernating Myotis species to white-nose syndrome mitigation tactics
Bat Research Research collaboration: Robin Russell (NWHC), Tonie Rocke (NWHC), Wayne Thogmartin (UMESC), Evan Grant (PWRC) White-nose syndrome is a fungal disease devastating cave-hibernating bat species ( Myotis spp.) in the eastern United States. Several mitigation tactics have been proposed to alleviate the effects of white-nose syndrome on bats including probiotics and vaccination. Questions...
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...
Blue-winged Teal and Cross Continental Avian Influenza Transmission
This project focused on improving our understanding of the migratory ecology of Blue-winged Teal and their ability to transmit avian influenza or other pathogens across the wild bird – domestic poultry interface.
Highly Pathogenic Avian Influenza Seaduck Challenge Study
This project seeks to improve our understanding of the susceptibility and pathogenesis of pertinent strains of avian influenza viruses in diving duck species.
Avian Influenza Surveillance in Waterfowl in the Atlantic Flyway
This project seeks to quantify the strains and prevalence of avian influenza viruses circulating in wild waterfowl across the Atlantic Flyway, and allow comparison with the nations other flyways.
USGS Wild Bird Avian Influenza Program – Studies from Endemic Regions of Eurasia
This project focuses on tracking wild birds throughout Eurasia via satellite telemetry to better understand their spatiotemporal movement patterns, relationship to domestic birds, and potential role in the spread, persistence, and amplification of avian influenza viruses.
Algal Toxins and Wildlife Health
Harmful algal blooms (HABs) have the potential to harm fish and wildlife, domestic animals, livestock, and humans through toxin production or ecological disturbances such as oxygen depletion and blockage of sunlight.
International Reporting of Wildlife Diseases of Interest
Reporting of wildlife diseases is important to build situational awareness regarding wildlife health, build national and global knowledge capacity, increase coordination among agencies, and integrate wildlife health data into other surveillance frameworks .
Disease
Disease is a major threat facing amphibian and reptile populations around the world. Our research addresses interactions between pathogens, the environment, and hosts to better understand ways to prevent the spread of disease.
