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