Herpetology



Hyla crucifer - spring peeper - click to enlargeThe Southeast Amphibian Research and Monitoring Initiative (SE ARMI) at USGS - Gainesville has conducted research on reptiles and amphibians in the Southeastern United States and Caribbean over the last 30 years. The project began with studies that assessed status and distribution of amphibians and reptiles in threatened Florida biotic communities. Since then, our research has expanded to focus on the life histories, diversity, and importance of amphibians and reptiles in a wide variety of Southeastern and Caribbean ecosystems.
