报告人简介：
Scott Nielsen is an Associate Professor of Conservation Biology in the Department of Renewable Resources at the University of Alberta. His interests are in terrestrial ecology (plant & animal) and its applications to the field of conservation biogeography, using methods that blend field studies of species with remote sensing, GIS, and statistical modeling/forecasting. The geographic focus of his work is the boreal and hemi-boreal forests of western and central Canada and the Canadian Rocky Mountain montane forests.

报告内容简介:
In this talk Scott Nielsen will discuss the ecology and conservation of brown bears (Ursus arctos) in the southern Canadian Rocky Mountains where he has been working since 2000. Specifically, he will relate habitats to grizzly bear behaviours (habitat selection), occupancy-abundance, body size (proxy of fitness), and climate change threats. He will emphasize how tradeoffs between top-down processes (human-caused mortality) and bottom-up factors (food supply) relate to patterns in landscape change (forestry and mining) and the importance of bottom-up regulation of bears. Finally, Scott Nielsen will explore how landscape factors and forest stand characteristics relate to fruit production in the most abundant shrub, Canada buffaloberry (Sheperdia canadensis), and how this affects spatial-temporal patterns in brown bear habitat use.
