Research to date has examined phylogenetic relationships of small mammals at the inter- and intraspecific taxonomic levels. This has involved the sequencing of genes (mitochondrial and nuclear) appropriate for this level of taxonomy.
A specific aspect of this research has focused on elucidating phylogenetic relationships within a species complex (9 species) of long-tailed shrews (Sorex) geographically centered in western North America. Phylogenetic analysis of mitochondrial DNA sequences has uncovered divergent molecular lineages not reflected by existing taxonomy that was based on previous analysis of morphological characters.
A student will be involved from the outset of this project supported from the negotiated start-up funds. This student will learn and carry out techniques involved in preparing a genomic library for isolation of microsatellites. The proposed project will provide opportunities across several different disciplines including molecular biology, molecular systematics, population genetics, and molecular ecology. Future expansion of this project may also include fieldwork opportunities for students. I also anticipate that my research will attract additional students with interests in molecular biology, population genetics, systematics, field biology, and ecology.
