Frank van Manen is an ecologist who blends his research interest in large carnivores with landscape ecology and is the team lead of the Interagency Grizzly Bear Study Team.
Research Interests
Frank's research focus is on 1) grizzly bear and black bear ecology and management, 2) demographic models to inform large carnivore management, 3) resource selection and energy landscapes, 4) wildlife genetics, and 5) international bear conservation.
Formerly, Frank spent 12 years with the USGS Leetown Science Center specializing in responses of mammals to landscape changes, management of large carnivores, and habitat models to support protection and restoration of plants and trees.

The Effects of Climate Variability and Change on Human-Bear Conflict in North America
Human-bear conflicts are a common problem and management priority for many wildlife agencies in North America. Bears are adaptable to anthropogenic activity and food sources which creates opportunities for conflict including property damage, livestock depredation, and human injury. Acute climate events and long-term directional climate change can exacerbate human-wildlife conflict by changing reso
Interagency Grizzly Bear Study Team
The Interagency Grizzly Bear Study Team (IGBST) is an interdisciplinary group of scientists and biologists responsible for long-term monitoring and research efforts on grizzly bears in the Greater Yellowstone Ecosystem (GYE). The team was formed by the Department of the Interior (DOI) in 1973 as a direct result of controversy surrounding the closure of open pit garbage dumps within Yellowstone...
