William Newmark, Ph.D.
William Newmark is a Research Associate and Conservation Biologist in the Natural History Museum of Utah. He holds a B.A. in Biology from the University of Colorado, a M.S. in Wildland Management from the University of Michigan, and a Ph.D. in Ecology from the University of Michigan. His research is focused on patterns of extinction of vertebrate species, protected area and wildlife corridor design, and animal movement. His findings on patterns of extinction of large mammals in western North American and Tanzanian parks and birds on tropical forest fragments have highlighted the problems that nature reserves face in conserving biological diversity and have provided an important justification for a series of worldwide initiatives to link national parks and related reserves with wildlife corridors. He has been conducting field research for over twenty-five years in western North America and East Africa. He has written two books and over more than 100 scientific papers and technical reports. He also serves as an international consultant in conservation biology to a number of bilateral and multilateral donor organizations and has been a chief technical adviser on several conservation projects in East Africa.
