Dr. Ryan O’Shaughnessy is an Assistant Professor and Research Scientist with the Borderlands Research Institute in the Department of Natural Resource Management. Ryan’s current research focuses on the effective management and restoration of pronghorn to the Trans-Pecos region of West Texas, interactions between aoudad and desert bighorn sheep, waterfowl and wetland ecology in arid environments, and the use of quail as indicators of rangeland quality. Further research interests include agricultural business relating to hunting in rural communities, game-species management and ecology, species distribution and habitat selection, foraging ecology, and human-wildlife conflict.

Before moving to Alpine, Ryan worked at Southern Illinois University Carbondale. His dissertation tested the ideal free distribution in spring migrating waterfowl as well as exploring processes governing habitat selection by migrating ducks. He received his MS from the University of the Witwatersrand in Johannesburg, South Africa. His thesis examined competitive interactions of puku and lechwe antelope in the Chobe National Park of Northern Botswana. He completed his BS.Hons at the University of the Witwatersrand where he studied diet selection and nutritional status of two populations of sable antelope in the Kruger National Park, South Africa. He also completed a BS in Zoology at the University of the Witwatersrand.
