Biography

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.

Expertise

Mammal Evolution and Ecology, Mammal Conservation, Biogeography, Phylogeography, Conservation Biology, Origins of Western North American Animals, Plants, and Biological Communities

Additional Information

Research in my laboratory spans a broad array of vertebrate, invertebrate, and plant groups, but generally asks questions about the history and structure of biological species and communities in western North American deserts, grasslands, and mountains. We use conceptual frameworks ranging from systematics through population genetics; analytical approaches ranging from historical biogeography through phylogeography and landscape genetics; and data that includes DNA sequences as well as morphological variation. Many of these research questions provide a basis to better predict the consequences of human-based landscape alterations and climate changes on the future of biological diversity. I am also an editor for the Journal of Biogeography, an author on the most comprehensive text and reference book on biogeography, and write about the historical development of biogeography as a modern science.
