Research Interests: I employ molecular and field approaches to address queries in conservation biology. I am particularly interested in how genetic diversity and structure within and among wild populations reflect population history, animal behavior, and species’ basic biology. My work falls into four arenas: phylogeography, responses of within-population processes to habitat fragmentation, information about cryptic species obtained via non-invasive genetic sampling, and the manner by which genetic diversity of foundation (keystone) species ramps up to effect diversity of associated communities. In the Cottonwood Ecology Group, my major focus involves determining how selective foraging by a foundation mammal, the American beaver (Castor canadensis), impacts the genetic diversity and structure of a foundation tree (Populus spp), and how this in turn impacts the diversity of dependent arthropod communities. This work is important because interactions among foundation species and the genetic basis for their disproportionate effects have been identified as major frontiers in ecology, and because riparian areas in the American West are hotspots of biodiversity that are rapidly disappearing.
