RESEARCH PROJECTS

My research interests are rooted in the ecology and natural history of vertebrates.   Specific projects focus on population ecology: geographic distribution, movements, reproduction, and conservation of reptiles and amphibians. Current research projects are as follow:

1. Population ecology and conservation of the Alabama Red-bellied Turtle
2. Herpetological survey of the Upper Mobile/Tensaw Delta
3. Status of the Mississippi Diamondback Terrapin along coastal Alabama
4. Vertebrate road-kill survey along the Mobile Bay Causeway (US90/98)
