Research Interests

Emeritus Professor Ehrhart is a vertebrate zoologist whose research program is focused on reproduction, population biology, ecologic geography, and conservation biology of marine turtles. His most recent research interest involves characterization of juvenile and subadult populations in coastal lagoons and over near-shore reefs, as well as long-term studies of nesting beach productivity. He is broadly interested in herpetology and mammalogy, particularly the distribution, ecology, and conservation of Florida amphibians, reptiles and mammals. He was an invited contributor to the World Conference on Sea Turtle Conservation and the Western Atlantic Turtle Symposia (I and II) and served recently as Team Leader of the Southeastern Region Loggerhead and Green Turtle Recovery Team. His students have studied the biology of vertebrates as diverse as Hylid frogs, Kinosternid and Emydid turtles and wood storks.
