New Genetic Test Detects Manatees' Recent Presence in Waterways
WARC scientists have developed the first lab test that can pick up traces of manatees' genetic material in fresh or saltwaterLearn more
WARC conducts relevant and objective research, develops new approaches and technologies, and disseminates scientific information needed to understand, manage, conserve, and restore wetlands and other aquatic and coastal ecosystems and their associated plant and animal communities throughout the nation and the world.

Sea turtles, pythons, & manatees, oh my: USGS science in FloridaLearn more
Hurricanes Harvey, Irma, Maria, and Nate may have spread non-native freshwater plants and animals into new water bodies, where some of them can disrupt living communities or change the landscape.
Environmental DNA picks up traces of the elusive mammals’ saliva, skin, waste, or exhaled breaths.
Florida's second-largest turtle rescue of 21st century is “exhausting, inspiring,” USGS biologist says
Establishment of the exotic invasive Cuban treefrog (Osteopilus septentrionalis) in Louisiana
The Cuban treefrog, Osteopilus septentrionalis, is native to Cuba, the Bahamas, and the Cayman Islands, and is invasive in areas where it has been introduced and established in the Caribbean as well as Florida. Despite repeated occurrences in several states over many years, it was not believed that Cuban treefrogs had successfully established...Glorioso, Brad M.; Waddle, J.

The Florida manatee (Trichechus manatus latirostris) T cell receptor loci exhibit V subgroup synteny and chain-specific evolution
The Florida manatee (Trichechus manatus latirostris) has limited diversity in the immunoglobulin heavy chain. We therefore investigated the antigen receptor loci of the other arm of the adaptive immune system: the T cell receptor. Manatees are the first species from Afrotheria, a basal eutherian superorder, to have an in-depth...Breaux, Breanna; Hunter, Margaret; Cruz-Schneider, Maria Paula; Sena, Leonardo; Bonde, Robert K.; Criscitiello, Michael F.
Coastal estuaries and lagoons: The delicate balance at the edge of the sea
Coastal communities are increasingly concerned about the dynamic balance between freshwater and saltwater because of its implications for societal, economic, and ecological resources. While the mixing of freshwater and saltwater sources defines coastal estuaries and lagoons, sudden changes in this balance can have a large effect on critical...Conrads, Paul A.; Rodgers, Kirk D.; Passeri, Davina L.; Prinos, Scott T.; Smith, Christopher; Swarzenski, Christopher M.; Middleton, Beth A.
