From University of Manitoba News:
Researchers found that human activities change where deer are on the landscape, and wolves tend to go where the deer are. They also found that wolves leverage human infrastructure to their advantage.
Sean Johnson-Bice, who led the project, says it took very intensive field work to come to these conclusions. He and his team went out and captured wolves to install GPS collars on them.
They then visited every single location where a wolf spent more than 20 minutes.
“We’re basically going out there like crime scene investigators looking for evidence of a kill,” he said.
