Associate Research Professor of Biology, Pennsylvania State University
Derek E. Lee is a quantitative wildlife biologist with expertise in conservation biology and population ecology. Current research investigates Masai Giraffe and other large mammal populations within a fragmented landscape in Tanzania. This work examines how births, deaths, and movements of ungulates are impacted by increasingly fragmented wildlife habitat, and what conservation actions are most effective. He spent 10 years researching the impacts of climate and ocean conditions on survival, reproduction, and population growth rates of marine predators such as northern elephant seals, Common Murres, and Cassin's Auklets at the South Farallon Islands, California. His work was included in a conservation and management plan for seabirds in the California Current. He also studied migration of Black Brant in Humboldt Bay as well as fire ecology of small mammals in California's oak woodlands and California Spotted Owls in the Sierra Nevada. Dr. Lee is an author on more than 40 peer-reviewed publications and dozens of popular science articles.
