| Background |
|
Dr. Steve Johnson, Assistant Professor of Urban Wildlife Ecology, holds a 60% teaching and 40% extension position in the Department of Wildlife Ecology and Conservation. Before joining the University of Florida Dr. Johnson worked as the State Sea Turtle Program Coordinator in North Carolina, and as a research wildlife biologist with the US Geological Survey. At the US Geological Survey he coordinated efforts for the national Amphibian Research and Monitoring Initiative in the southeastern United States. Dr. Johnson's area of expertise is natural history and conservation of amphibians and reptiles, and he has worked extensively with imperiled species. His current extension and research programs emphasize invasive wildlife biology, urban wildlife education, and prescribed fire effects on wildlife. He is an associate editor for the journal Herpetological Review and member of the Society for Conservation Biology, Herpetologists League, and The Wildlife Society. |
