My research has concentrated on examining nutrition as a mechanistic thread between environmental variation (e.g., winter severity, habitat composition) and population variation of large ungulates, as well as of wolves. In an effort to expand the biologist's and manager's understanding of habitat requirements and enhance conservation efforts, I have employed experimental and natural comparison designs, often in long-term studies, to examine the effects of seasonal weather conditions, habitat alteration, nutritional restriction and recovery on physiological indices, body condition, food habits, movements, habitat use, age-specific survival and reproduction. Specifically, my collaborative research has involved white-tailed deer and wolves in northern Minnesota; elk and bison in Yellowstone National Park, before and after the historic fires of 1988; moose on Isle Royale and in northern Minnesota; and elk and mule deer in Arizona.
