The scale dependence of population density in mammals

Current Research
Alberta’s boreal forest faces unprecedented cumulative impacts of oil and gas, forestry, agricultural, urban, and transportation land uses.  The effects of these changes on biodiversity are unclear, yet understanding them is necessary for effective land use planning.  Two contrasting theories, Niche Theory and the Unified Neutral Theory of Biodiversity, predict markedly different shapes of local species extirpation and community disassembly.  As a result, there is considerable uncertainty in how human activities will affect biodiversity in real landscapes, even with empirical data.  My research will provide an empirical evaluation and mechanistic foundation for the shape of the relationship between human impacts and biodiversity in Boreal Alberta.
