Wolf, ungulate, aspen ecology; trophic cascades; mesopredators; plant/animal interactions; ecology of fear; wildlife habitat analysis; landscape ecology; biodiversity; historical ecology; conservation biology; riparian ecology.

Current/Recent Programs:

The Leopold Project - The goal of Leopold Project is to continue the work Aldo Leopold started on topics that intersect forestry and wildlife science and ecosystems especially predators, ungulates, and forests.
