Dr. Stapp is an ecologist who studies behavioral, population, and community ecology of wildlife species, particularly mammals, in arid and semi-arid ecosystems, and applied problems related to their conservation and management. His research interests are varied and include both field and laboratory-based projects, almost all of which involve undergraduates or graduate students (MS Biology, MS Environmental Studies). A native of northern California, he earned his BS in Zoology from UC Davis, a MS in Wildlife from the University of New Hampshire, and his PhD in Zoology-Ecological Studies from Colorado State University. Following postdoctoral research projects at the University of Wyoming and UC Davis and a Lecturer position at the University of York (UK), he joined the Department of Biological Science at CSU Fullerton in 2002, where he teaches courses in ecology, conservation biology, and mammalogy, as well as graduate courses.
