Dr. Harrison’s research program is focused on habitat ecology, predator-prey relationships, and community interactions among forest wildlife, and particularly among mammalian carnivores and their prey. Recent projects have addressed habitat ecology of Canada lynx and snowshoe hares, long-term population and spatial dynamics of hares in the Acadian forest, broad-scale patterns of habitat occupancy of lynx and American martens, application of forest carnivores as umbrella species to assist in landscape-scale planning for future habitat supply in commercially managed forests, conservation of the threatened Newfoundland marten, ecology and inter-specific interactions among carnivores and their prey in Acadia National Park, and effects of forest management activities in northern Maine on spruce grouse. Prior to joining the faculty in 1988, Dr. Harrison served as a Wildlife Research Supervisor in a state wildlife management agency. Over the years, Dr. Harrison has been involved in extensive research on the ecology and inter-specific relationships of the eastern coyote, red fox, American marten, and Canada lynx. He is engaged in research and conservation efforts with mammalian carnivores and other forest wildlife at international, national, regional, and state levels and his work often integrates habitat modeling, habitat conservation, and landscape planning. Dr. Harrison teaches several courses related to his research including the co-capstone wildlife-habitat relationships course at the senior level, as well as courses in habitat assessment and predator ecology at the graduate level.
