Avian Influenza Host Movement Ecology
Understanding disease systems requires an understanding of the basic ecology of host species. USGS is involved in global efforts to explore the movements of bird species that are hosts of avian influenza as well as the potential impacts of changing landscapes on avian influenza.
Avian Influenza Spread, Prevalence and Persistence
USGS researchers seek to understand the factors influencing the spread and persistence of avian influenza viruses on the landscape. This research also addresses how novel strains of highly pathogenic avian influenza are impacting a larger number and diversity of host species, including waterfowl, shorebirds, raptors and other birds.
Understanding Avian Influenza Exposure and Antibodies in Understudied Species
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.
Using Telemetry to Understand Overlap in Habitat Use Between Waterfowl and Agricultural Birds in North America
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.
Investigating Blotchy Bass Syndrome in Black Basses (Micropterus spp)
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.
AquaDePTH-Aquatic Disease and Pathogen Repository
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...
Northeast Amphibian Research and Monitoring Initiative
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.
Integrating Science and Management to Assist with the Response to Stony Coral Tissue Loss Disease
A USGS multi-disciplinary team will use laboratory and modeling approaches to investigate the cause of stony coral tissue loss disease.
A case study of temporal trends in risk factors associated with endocrine disruption in smallmouth bass
Issue The USGS has a long-term research effort that identified endocrine disruption in smallmouth bass (SMB) in the Chesapeake Bay watershed. Endocrine disruption can cause many changes in fish, including intersex characteristics where fish develop characteristics of the other sex, such as immature eggs forming in males. An overview by USGS of endocrine disruption in fish found the condition...
Agricultural best management practices can improve water quality and conditions for fisheries in the Chesapeake Bay Watershed
Issue Partners in the Chesapeake Bay Program (CBP) are implementing best management practices (BMPs) to prevent nutrient and sediment from entering waterways across the Chesapeake watershed and reduce loads to the Bay. In addition to reducing nutrients, CBP partners want to better understand how BMPs can provide additional benefits for addressing toxic contaminants, such as pesticides, hormones...
Fish and Aquatic Animal Health Publications, 2021 – 2022
Below are journal articles about fish and aquatic animal health from the Eastern Ecological Science Center published in 2021 and 2022.
Point and Non-Point Sources of Endocrine Disrupting Compounds and the Potential Effects on Fish and Frogs in the New Jersey Pinelands
This project, in collaboration with the NJ Pinelands Commission and the USGS NJ Water Center, is evaluating potential effects of endocrine-disrupting chemicals from point and nonpoint sources in the Pinelands Area, a research cluster as part of the Delaware River Watershed Initiative.
