Behavioral ecology; sexual selection; herpetology
Dr. Stephenson’s research focuses on the ecology and evolution of reptiles and amphibians. First, he is interested in the functional significance of body coloration in these groups and how such variation may relate to differences within and between sexes in other aspects of anatomy, physiology, and behavior. Second, he collaborates on studies of life history variation of lizards of Mexico, with an eye to understanding how such variation may contribute to the formation of new species. Third, he is exploring the amphibian and reptile diversity of a tract in nearby Crawford County, work that is both revealing new populations of species of conservation concern, and helping better characterize the regional diversity of herpetofauna overall.
