Research Summary

Dr. Bushar's research interests are in the ecology and population genetics of threatened and endangered snake species. Most of her work has focused on the Timber Rattlesnake, Crotalus horridus, which is a candidate species in Pennsylvania and is a threatened or endangered species in most of the northeastern United States. With colleagues, she has developed microsatellite genetic markers for use in studies of C. horridus (Villarreal et al., 1996). She has used these to study factors influencing genetic variation within and gene flow among local populations of C. horridus (Bushar et al., 1998) as well as anthropogenic and physiographic influences on the genetic structure of C. horridus populations (Bushar et al., in press).  Additionally, Dr. Bushar has a research program on the island of Aruba in the Netherlands Antilles studying the endangered Aruba Island Rattlesnake, Crotalus durissus unicolor, and the invasive Boa constrictor (e.g., Reinert et al., 2008; Bushar et al., in press). Dr. Bushar has been supported by funding from the Pennsylvania Wild Resource Conservation Fund through the Pennsylvania Fish and Boat Commission and a State Wildlife Grant through the Pennsylvania Fish and Boat Commission. Her research has been supported through intramural grants including the Stacy Anne Vitetta Professorship, the Ellington Beavers Faculty Research Award, and other intramural grants. She has also received support for the renovation of research laboratories and the purchase of instrumentation used in both teaching and research through the National Science Foundation.
