Species Stressors

Research into the cause and mitigation of environmental and anthropogenic stressors that potentially impact the health and reproductive capacity of species of management concern. Current focal areas include conventional and unconventional energy development (oil, gas, wind, solar, hydroelectric), ecological flows, land use, and agriculture.

Health Effects and Behavioral Response of Florida Manatees (Trichechus manatus latirostris) to Persistent Algal Bloom and Associated Loss of Seagrass Resources in Brevard County, Florida

USGS researchers are working with partners to assess the health and foraging behavior of Florida manatees in the northern Indian River Lagoon and Banana River, areas that have experienced declining seagrasses due to an extended phytoplankton bloom.

Quantitative Framework to Model Risk of Collisions between Marine Wildlife and Boats

Collisons between wildlife and vehicles threaten many species, and can lead to human loss of life, injuries, and loss of property. USGS is developing models to help evaluate the effectiveness of wildlife protection zones and optimize the design of these protected areas.

Studying Immune Responses in the American Kestrel (Falco sparverius)

The objectives of this study are to (1) investigate whether the immune system will respond to chemical stressors, such as new flame retardant compounds, and (2) determine if such chemical stressors influence white blood cells (WBC) responses after exposure to a viral pathogen mimicking bird flu.

An Online Portal for Managing and Reporting Annual Piping Plover Monitoring Data

Federally-listed as threatened since 1986, the Atlantic Coast Piping Plover (Charadrius melodus) population comprises fewer than 2,000 breeding pairs, according to the most recent census data. These breeding pairs are the target of the U.S. Fish and Wildlife Service’s (USFWS) species recovery plan.
