Research
In general, our research explores how environment, physiology and behaviour influence the abundance, distribution, and coexistence of mammal populations. Our research is conducted both in the lab and in the field, often in collaboration with northern communities or one of our many partners.

One of our research focuses is on energetics (the process by which animals acquire and assimilate energy from the environment, and allocate assimilated energy between maintenance, growth, and reproduction). We firmly believe that understanding the ecological implications of energetics ultimately requires field studies that integrate measures of energy intake and expenditure, under conditions of known resource availability, and in situations where behaviour, survival and reproductive success can be documented. Another of our research focuses is on understanding, predicting and monitoring environmental change impacts on northern wildlife and traditional food security in Canada.
