Research Interests: 

My principal interest is the relationship between food and the survival, growth and reproduction of animals. I have collaborated with scientists and students to work on mammals, birds and reptiles in both captive and wild populations. I am most interested in the ways animals solve the problems of variable environments because animals must reduce their costs of living when food supplies decline but also quickly replenish their body stores when food becomes more available. Variable nutrition is a concern for wildlife that live in temperate and polar regions where seasonal changes in light, temperature and plant growth are pronounced but also vary between years to affect the supply of food along migration paths, at breeding grounds and in overwintering areas. Fires, storms and human development of habitats can alter the nutrition of wildlife and affect the growth of populations. I am currently working on the effects of seasonal changes in food quality on digestion, body condition and reproduction of caribou and moose.
