We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Title: Edge effects on caribou population: modeling via advection-diffusion

Abstract: I will present a model of caribou movement in the case where a road or logging in forests perturbs the home range of caribou. A probabilistic approach is used to describe the movement of caribou and by a limiting process, an advection-diffusion (Fokker-Planck) equation is obtained. The parameters of the model are estimated using data obtained from northern regions of Québec by the team of D. Fortin (Biology, U. Laval) and R. Courtois, C. Dussault (MRNF, Québec). Simulations of the model are performed using the finite element method with a Streamlined-Upwind Petrov-Galerkin formulation. The main result predicts a density peak of the population at about 4.6 km from the boundary of a road or a clear cut and this prediction is verified using an independent data set. This is joint work with D. Fortin, A. Fortin, N. Courbin, C. Tye-Gingras (Laval), P. Moorcroft (Harvard), R. Courtois and C. Dussault (MRNF, Québec).
