Bio/Research

My research focuses on the effects of behavioural decisions by terrestrial mammals on population dynamics and community structure. A mix of theoretical and empirical approaches is used to consider the dynamics of specific systems. Theoretical questions of interest include herbivore migration in relation to resource use and predation risk, carnivore and herbivore spatial distribution in relation to resource use and predation risk, optimal diet and patch selection in heterogeneous environments, and the effect of social interference and territoriality on predator-prey interactions.

Empirical work is currently underway in several systems: wildebeest and Thomson's gazelles in Serengeti National Park (Tanzania), elk in Banff National Park (Canada), elk in Bancroft, Ontario (Canada), plains bison in Prince Albert National Park (Canada), mustelid carnivores in Red Lake, Ontario (Canada), and small mammals in Algonquin Provincial Park, Ontario (Canada). Theoretical models are used to assess the dynamic implications of behavioural strategies associated with trophic interactions. This mixture of experimental data and model predictions is compared with long-term observational data to interpret temporal dynamics and community structure of free-living plant and mammal communities in natural reserves. Research on landscape determinants of elk movements is currently underway with Dr. Daniel Haydon.
