ROB SERROUYA has worked as a large mammal ecologist in mountainous areas of southern British Columbia and Alberta for 15 years. He specializes on broad-scale processes, particularly how forest management affects trophic interactions within ecosystems that typically did not have much early seral vegetation. How this shift in vegetation, from old forests to shrubs, affects the abundance and interactions among herbivores and carnivores is one of his main research interests. He currently works on the endangered mountain ecotype of woodland caribou, and focuses on how the changing dynamics of other herbivores (moose and deer) and carnivores (bears, wolves, and cougars) affects the survival of mountain caribou. Using adaptive management has always been one of his main interests and as such he is monitoring how a broad-scale reduction in moose abundance affects the dynamics of wolves and caribou.
