Dr. Douglas Clark (PhD) is an associate professor with the School of Environment and Sustainability (SENS) at the University of Saskatchewan (USask).
In an unprecedented finding, Clark and his colleagues recorded polar, black and grizzly bears occupying overlapping territory in Manitoba's Wapusk National Park.
While the three three bear species don't usually live in the same space, bear territories seem to be changing.
"I think it's entirely possible that grizzlies may have or will show up in northern Ontario," Clark said in a recent interview with CBC News.
"It's very likely that these bears in northern Manitoba have come from a source population in Nunavut, that is expanding east out the the Hudson Bay coast ... and to the south east, into Manitoba."

This USask research also included Ryan Brook (associate professor in the College of Agriculture and Bioresources); Chelsea Oliphant-Reskanski, Michel Laforge and Kiva Olson (former students in SENS and the College of Arts and Science), and Danielle Rivet (student in the College of Arts and Science).
