USGS researchers are a developing a modeling framework to assess climate warming impacts on hypoxia-related stress to commercially and recreationally important Gulf species.

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

USGS is partnering with U.S. Army Corps of Engineers to digitize 20 years of historic sea turtle relocation trawling reports from over 50 sites across nine states.

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.

The USGS is participating in the Louisiana-Trustee Implementation Group Monitoring and Adaptive Management work group to assess the injuries caused by the Deepwater Horizon oil spill and to select the appropriate restoration measures to compensate the public for the injury to coastal and marine resources.

Connectivity among coral communities influences the probability of speciation and contributes to their ability to adapt to natural and anthropogenic stressors. Results from this study will enhance our understanding of Gulf ecosystems with regional conservation initiatives to inform the restoration of degraded deepwater coral communities and preserve long-term viability of coastal ecosystems.

WARC scientists work with local partners to verify and document sightings of non-native marine fishes.

WARC researchers partnered with Gulf Sturgeon decision makers and biologists to develop a Bayesian network model that uses habitat characteristics to predict the quantity of juvenile winter foraging habitat under alternative river discharge and timing of juvenile arrival scenarios.

DISCOVRE ( DIversity, Systematics and COnnectivity of Vulnerable Reef Ecosystems) is an integrated, multidisciplinary, international effort investigating the unique and fragile deep-sea coral environments from the microscopic level to the ecosystem level.

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.

This website provides access to the list of imperiled freshwater and diadromous fishes of North America as determined by the 2008 American Fisheries Society (AFS) Endangered Species Committee (ESC) on Fishes.

It's hard to imagine a better job than doing fieldwork with the USGS Coastal Ecology crew as they work to keep tabs on the Gulf sturgeon population.
