Research Overview: My thesis research focused on conducting surveys for the state-threatened Western Ribbonsnake (Thamnophis proximus) across eastern New Mexico in order to validate a habitat suitability model for the species created by the New Mexico Department of Game and Fish and to generate current distribution and ecological data on this species. These data will help identify population trends, answer life history and natural history questions, and better understand the threats that this species faces across the region. I am also working on a project mapping core and peripheral populations of the parthenogenic New Mexico Whiptail (Aspidoscelis neomexicanus) across its range in the southwestern USA.
