Research

My research interests focus on the ecology and conservation of wetland- and prairie-dependent wildlife, particularly waterfowl. For the last several years I have worked with a team of scientists from Ducks Unlimited Canada on several long-term studies of factors limiting productivity of dabbling ducks in the Canadian Prairies. One outcome of this research has been the development of spatially explicit models that predict the abundance and reproductive success of waterfowl as a function of landscape attributes. These models then become important planning tools for the delivery of future conservation programs.
