Genetic variation of Coues white-tailed deer in two landscapes of the southwestern United States. Hybridization between mule deer and Coues white-tailed deer in the southwestern United States. The use of weathered antlers as a source of DNA for molecular genetic studies. Multiple peer reviewed publications based on thesis. Facilitate the use of microsatellite allele frequencies by wildlife managers to determine differences among Coues white-tailed, Eastern white-tailed, mule deer, and hybrid Coues white-tailed/mule deer. Provide insight into landscape determinants of molecular genetic variability of Coues white-tailed deer in the southwestern United States. Peer reviewed publications on wintering bald eagle utilization of local food sources.

    Rocky Mountain Research Station (RMRS) scientists have been at the forefront of efforts to understand the ecology of the threatened Mexican spotted owls (Strix occidentalis lucida) for more than 25 years. These scientists and their cooperators have produced most of the existing scientific information on this species. Today, RMRS scientists continue to be actively involved in developing new knowledge on this owl, synthesizing existing information, and working with managers to integrate habitat requirements for the owl and its important prey species into land management plans.
    Innovative quantitative approaches have been developed for evaluating wildfire and prescribed fire effects on wildlife communities in several western North American national forests.
    The avifauna within the Sky Islands of southeastern Arizona includes species found nowhere else in the United States. Rocky Mountain Research Station scientists initiated a study in the 1990s on avian distribution and habitat associations within the Sky Islands. This project involves monitoring vegetation and bird populations following wildfires, applying climate change models to assess potential changes and explore strategies for managing resilient forests and avian populations, and engaging citizens in data collection and long-term avian monitoring.
