Tools and Technology

USGS is working with partners to understand how the federally protected Florida manatee ( Trichechus manatus latirostris) population changes over time and responds to threats.

"BearTrak" is an app that provides a central repository for Louisiana black bear tracking data, allowing managers to access information more quickly and reliably. USGS science was used in the decision to delist the species from the Endangered Species Act in 2016. Louisiana Department of Wildlife and Fisheries continues to monitor the Louisiana black bear population.

The Gulf sturgeon, Acipenser oxyrinchus desotoi, has been listed as Threatened since 1991. Beginning in 1986, USGS has been investigating sturgeon population abundance and ecology throughout its range, but mostly in the Suwannee River.

USGS scientists are using a spatially-explicit Bayesian network model to predict the difference between energetic value and energetic demand for stopover habitats for migrating landbirds.

Using ecological and geographical data, WARC researchers and their partners are analyzing avian and benthic sampling on Whiskey Island and Caminda Headland to compare pre- and post-restoration aspects of habitat occupancy, habitat availability, habitat use, and kernal density estimation.

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...

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).

USGS scientists are studying American shad ( Alosa sapidissima), blueback herring ( Alosa aestivalis), and alewife ( Alosa pseudoharengus; collectively “alosines”) to develop robust genetic baselines that will inform management practices for individual species.

USGS is working to establish a new East Coast fish ladder design that would help a multitude of aquatic species move easier in our waterways.

This web-based mapping tool, released in 2024, enables users to identify which threats are driving the current status of Sagebrush Ecological Integrity (SEI), assess if SEI and associated threats, such as invasive annual grass, conifer encroachment, human modification - have changed over time, and visualize spatial trends in SEI and threats. The Sagebrush Ecosystem Trends Module supports managers...

Greater sage-grouse ( Centrocercus urophasianus) are at the center of state and national land use policies largely because of their unique life-history traits as an ecological indicator for health of sagebrush ecosystems. Researchers within the U.S. Geological Survey (USGS) and Colorado State University (CSU) worked with the Bureau of Land Management (BLM) and state wildlife agencies to develop a...
