Fields of Interest

Nutritional and physiological ecology of large mammals with an emphasis on animal-habitat interactions

Research

My research efforts have concentrated on examining the effects of nutritional restriction and recovery on body condition, physiological indices, and survival of northern ungulates, including white-tailed and mule deer, elk, bison, and moose, as well as wolves. One ongoing objective of my work has been to explore and develop improved means of directly and sensitively assessing the nutritional status of free-ranging animals so that we might better understand the relationships between habitat and other environmental factors (e.g., winter weather) and population dynamics. Currently, I am conducting a comprehensive, long-term study of the relationship between winter thermal cover and the movements, distribution, and population performance of free-ranging white-tailed deer with particular focus on nutrition as a mechanistic thread from the environment to the population.
