Interacting effects of climate and biotic factors on mesocarnivore distribution and snowshoe hare demography along the boreal-temperate ecotone
The motivation of my dissertation research was to understand the influence of climate and biotic factors on range limits with a focus on winter-adapted species, including the Canada lynx ( Lynx canadensis ), American marten ( Martes americana ), and snowshoe hare ( Lepus americanus ). I investigated...
