# overview
The principal focus of our research is the consequences of life history and environmental change on nutrition. Our current projects are focused on ungulates (e.g., reindeer, caribou, moose, muskoxen, white-tailed deer) but we also study waterfowl (e.g. ducks and geese) as well as non-game species (e.g. porcupines and bats) in both wild and captive populations. We attempt to provide information that will expand policy options for managing wildlife populations and their habitats.
