“Speciation in Rodents: A Look at Phylogenetic,
Biogeographic, and Population Genetic Relationships
in Three Genera of New World Rodents”

Dr. Brandi Coyner
Department of Natural Resources
University of Nevada, Reno

3:00-4:00 PM
Science 2, Room 109

Many pressures exist (global climate change, habitat conversion) that threaten native habitats and species, and a solid understanding of current levels of biodiversity and the processes that led to that biodiversity are needed for effective management and protection of vulnerable species. Rodents exhibit a high diversity of forms, occupy a variety of niches, occur in nearly all habitats, and represent more than 40% of mammalian species making them excellent models for the study of mammalian speciation and diversity. Phylogenetic relationships among the four species groups within the genus Akodon, with comments on taxonomic changes and validity of the four species groups, will be discussed. A biogeographic hypothesis explaining the extant diversity and species’ distributions within the genus Eligmodontia will be presented, as will the population genetic parameters and genomic level variation of a hybrid zone between two species of Neotoma. Discussions of future research will include additional study of the Neotoma fuscipes complex and revisiting the Heteromyid rodents of the genus Perognathus using recently developed genomic techniques and analyses.
