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
A new genetic analysis of invasive pythons captured across South Florida finds the big constrictors are closely related to one another. In fact, most of them are genetically related as first or second cousins, according to a study by wildlife genetics experts at the U.S. Geological Survey.
U.S. Geological Survey scientists have been honored as Recovery Champions by the U.S. Fish and Wildlife Service's Southeast Region for their long-term research efforts on the Florida manatee.
Exotic invasive Pomacea maculata (Giant Apple Snail) will depredate eggs of frog and toad species of the Southeastern US
Pomacea maculata (Perry) (Giant Apple Snail) is a freshwater snail native to South America (Hayes et al. 2015) that is an invasive species in the freshwater wetlands and waterways of the northern Gulf of Mexico, peninsular Florida (Benson 2017, Burks 2017) and globally (Hayes et al. 2015). Karraker and Dudgeon (2014) found that ...Carter, Jacoby; Johnson, Darren; Merino, Sergio
Global dynamics of a mutualism–competition model with one resource and multiple consumers
Recent simulation modeling has shown that species can coevolve toward clusters of coexisting consumers exploiting the same limiting resource or resources, with nearly identical ratios of coefficients related to growth and mortality. This paper provides a mathematical basis for such as situation; a full analysis of the global dynamics of a new...Wang, Yuanshi; Wu, Hong; DeAngelis, Donald L.
Internal parasites of the two subspecies of the West Indian manatee Trichechus manatus
The West Indian manatee Trichechus manatus is divided into 2 subspecies: the Antillean (T. m. manatus) and Florida (T. m. latirostris) manatees. This study reports sample prevalence of manatee parasites from populations of these 2 subspecies in different geographical locations. Although necropsy is a valuable diagnostic tool for parasite...Wyrosdick, Heidi M.; Chapman, Alycia; Mignucci-Giannoni, Antonio A.; Riviera-Perez, Carla I.; Bonde, Robert K.
