Professor
Ph.D. University of New Mexico, Albuquerque
Biogeography; Molecular Systematics of Mammals; Conservation Biology

Brett R. Riddle is a Professor in the School of Life Sciences at the University of Nevada, Las Vegas. His research focuses primarily on the history of biodiversity in western North America, with ongoing projects including: historical assembly of the warm desert biotas; phylogeography of Great Basin montane island biotas; and molecular systematics and biogeography of diverse North American rodent groups. He is cofounder and past President of the International Biogeography Society, an editor of the Journal of Biogeography, and and associate editor of Systematic Biology. He is a coauthor of "Biogeography: third edition", Sinauer Associates - the most comprehensive available textbook and reference book on Biogeography. "Biogeography: fourth edition" is scheduled for publication in 2010.
