A sow grizzly and a cub are seen on a wildlife overpass above the Trans-Canada Highway in Banff National Park. A genetics study by scientists with the Western Transportation Institute at Montana State University has examined the reproduction success of bears using wildlife crossings in Banff and determined that system of crossings has helped to maintain genetically healthy populations of black bears and grizzlies in the park.

Aerial view of Wolverine Overpass and the Trans-Canada Highway in Banff National Park, Alberta, Canada, where scientists with the Western Transportation Institute at Montana State University have been studying the impact of wildlife crossing structures on area bears. The photo is featured on the cover of the British journal "Proceedings of The Royal Society B," which has published a paper co-authored by former MSU graduate student Michael Sawaya, MSU professor Steven Kalinowski and WTI researcher Tony Clevenger.
