My research focuses on the
life-history evolution of mammals. My research has been mostly
field-related but now I am working on incorporating laboratory-based
elements. For my dissertation, I examined the effects of age and previous
breeding experience on survival, reproductive success, reproductive
investment, and somatic investment in Columbian (Spermophilus columbianus) and
Since I am interested in not only mammals, students who work with me will have the opportunity to a variety of field projects dealing with mammals, birds, amphibians and reptiles. Projects can be highly specialized or natural history related. Most recently (Winter 2007), two students (Amanda Smolarek and Kyle Hopkins) carried out a study on winter reproduction of Peromyscus sp. in Rider Park, just north of Williamsport. This summer (2007), Matt Wright, Nathan Hanner, and I are working on a variety of projects involving small mammal trapping in the area around Williamsport. I will be collaborating with the Nature Conservancy on monitoring the effects of different forest treatments on small mammal populations at the West Branch Wilderness Preserve in Clinton County. The treatments include herbicide application and timber thinning and are designed to restore the forest to more "natural" conditions.
