Conservation Genetics

USGS scientists lead activities that are central to bird conservation and support both wildlife and communities. Through close collaboration with conservation partners, our scientists are meeting real-world needs—from maintaining sustainable harvest opportunities to advancing species recovery efforts.

Explore seven case studies highlighting how USGS bird research informs real-world decisions.

The USGS Eastern Ecological Science Center (EESC) provides world-class science to inform natural resource decisions on aquatic ecosystems, species populations and management, disease, and invasive species. Our scientific products represent critical contributions that enhance the ecological and economic sustainability of recreational and commercial fishing. In the United States, anglers contribute...

The Molecular Ecology Laboratory applies innovative genetic and genomic technologies to address a variety of complex questions and issues facing the Nation's natural resources. While we continually update the scale and efficiency of laboratory procedures to meet stakeholder needs, we must also be innovative and flexible in addressing those needs that have no off-the-shelf solution. We help...

Once numbering in the tens of millions, plains bison ( Bison bison bison) were nearly driven to extinction with only a few hundred individuals remaining by the late 19th century. Plains bison have since recovered to approximately 20,000 animals managed in conservation herds throughout North America, yet substantial challenges to their recovery remain. The Department of the Interior (DOI) stewards...

USGS science in support of the Department of the Interior's Bison Conservation Initiative.

Due to the rapid decline in abundance of Yellow Lampmussel ( Lampsilis cariosa) and Tidewater Mucket ( Atlanticoncha ochracea), USGS and partners at the U.S. Fish and Wildlife Service (USFWS) and Central Michigan University (CMU) are conducting an assessment of genetic diversity and population structure to inform appropriate recommendations for conservation and management of each species. These...

Flow cytometry is a technique for rapidly analyzing large numbers of animal cells using light-scattering, fluorescence, and absorbance measurements.

USGS scientists are using innovative combinations of telemetry, genetics, and side-scan Sonar to support conservation of endangered Atlantic sturgeon ( Acipenser o. oxyrinchus).

Climate change will expose many species to novel extreme environmental conditions, that may test organisms’ ability to respond to environmental change. Local adaptation, when a species evolves to be more suited for its local environment, can be an indicator of whether a species is likely to persist in the rapidly changing environment. Habitat specialists, like the greater sage-grouse, have evolved...

Widespread anthropogenic development in the sagebrush steppe and shifting drought and wildfire patterns have contributed to the observed dramatic declines of the greater sage-grouse since the 1960s. Alteration of the sagebrush habitat can affect many aspects of the species life history, including survival and local resource use. Over many years, the combined effects of landscape composition on...

The greater sage-grouse is a sagebrush-obligate species that has experienced dramatic range-wide declines since the 1960s, causing significant conservation concern. Genetic information has refined our understanding of population structure, the levels of inbreeding or relatedness, allowed the ability to monitor for change over time, and has been used to understand the outcome of management actions...
