The Crown of the Continent Research Learning Center at Glacier National Park will present a brown-bag lecture talk by Cristina Eisenberg on wildlife interactions at the Community Building in the Park Headquarters complex on Wednesday, May 2, from noon to 1 p.m.

Eisenberg’s talk will be about her recently completed doctoral dissertation at Oregon State University on “The Complex Food Web of Fire, Aspen, Elk, and Wolves in Waterton-Glacier International Peace Park.”

For her master’s in environmental studies at Prescott College, Eisenberg studied wolf ecology and management, with a focus on the work of Aldo Leopold. She is the author of “The Wolf’s Tooth: Keystone Predators, Trophic Cascades and Biodiversity” and is working on a second book about the ecology and public policy underlying large carnivore conservation in the West.

Eisenberg currently is the research director at the High Lonesome Ranch in north-central Colorado, where her research interests involve living sustainably with large carnivores and utilizing food web concepts to restore ecosystems.
