My primary research interest is mammalian spatial ecology -- understanding how ecological and manmade elements influence home range size and location for particular species. In my lab, tools such as Geographic Information Systems (GIS), remote sensing technology, and molecular genetic techniques are employed to better understand these questions. My research emphasizes conservation biology because I work with species whose populations have been seriously altered as a consequence of habitat degradation and fragmentation. In addition to wildlife biology, conserving these species requires an intimate knowledge of political and legislative systems, and community-level human dimension practices. I have worked with a range of species, including mountain lions, Florida panthers, bobcats, coyotes, and Florida burrowing owls. My international research includes conservation projects for the puma, guanaco, and vicuna in South America and conservation of neotropical cats (ocelots, jaguars, jaguarundis) along the U.S.-Mexico border.
