In a 10-year study of grizzly bears living in and around the Rocky Mountains of Alberta, researchers have identified a 'silver spoon effect,' where bears born in more favourable conditions end up doing better, and the study's findings suggest warming temperatures due to climate change are part of this effect.
Gathering data on grizzlies ranging from the U.S.-Canada border all the way north to Grande Prairie, 112 bears in total, an international team of researchers found that those living in the foothills of the Rockies were larger and healthier than those living further up in the mountains. This is despite the fact that the foothills have suffered more 'forest disturbances' in the form of habitat loss due to human encroachment.
"It is kind of contrary to what you would think," said study lead author Scott Nielsen, a biologist at the University of Alberta, according to the Edmonton Journal.
It might be common to think that living further away from the human population would help the bears.Read More »from Study suggests that warming climate is good for Alberta’s grizzly bears
