USGS is creating spatially and temporally explicit inputs to improve avian influenza transmission risk modeling. This project places special emphasis on wild bird distribution and abundance models as well as avian influenza prevalence models.

USGS researchers are developing novel methods to improve our understanding of waterfowl distributions and abundance across the United States to inform a variety of ongoing disease studies. Understanding the distribution of wild waterfowl is a critical component to assessing avian influenza transmission risks across the landscape.

Recent outbreaks of highly pathogenic avian influenza have impacted a dramatically wider range of bird hosts than ever before. USGS researchers are working to identify which bird species have been exposed, which have developed immune responses, and how these species may influence viral ecology to inform risk management activities.

USGS researchers are using telemetry to improve our understanding of how wild birds move throughout their environments and the potential implications for disease transmission within and to domestic poultry.

This project focuses on understanding the forces driving the risk of avian influenza transmission from wild waterfowl to domestic poultry within the Chesapeake Bay region.

This project focuses on improving our understanding of how current and previous infection with avian influenza viruses impact the movement ecology of wild bird species.

USGS is studying the spread and effects of “blotchy bass syndrome” on black basses ( Micropterus spp). USGS and state agencies have partnered with citizen scientists and recreational organizations to create a continent-wide biosurveillance network to monitor the syndrome.

The Aquatic Disease and Pathogen Repository (AquaDePTH) will be a public-facing national repository to support biosurveillance of aquatic animal diseases and pathogens. By collating historically published data, plus new aquatic pathogen and disease information, stakeholders will be able monitor fish kill and aquatic pathogen trends spatially and temporally in freshwater and marine environments...

The U.S. Geological Survey’s Eastern Ecological Science Center is home to the Northeast Amphibian Research and Monitoring Initiative (NEARMI), one of 7 ARMI regions across the United States. NEARMI works on public lands in thirteen states from Maine to Virginia, including many National Parks and National Wildlife Refuges.

Disease dynamics in wildlife are commonly related to changes or increases in environmental stressors that are placed upon an animal. Environmental pollutants are known to affect the immune system of wildlife, resulting in impaired resistance to infection and potential increases in disease outbreaks. In collaboration with: Jill Jenkins, Ph.D USGS Wetland and Aquatic Research Center; Julia Lankton...

Agrochemical pollution poses a severe threat to biodiversity. Agrochemicals can detrimentally affect wildlife growth, development, survival, reproduction, and immune responses, which facilitates emergence and spread of infectious diseases that may cause unusually high mortality. Animal microbiota plays a fundamental role in host’s food detoxification and defense against pathogens, regulates...

This project seeks to improve our understanding of how domestic ducks move throughout the market chain in China and the role this may play in the amplification and spread of avian influenza viruses.
