Great podcast episode. I am definitely one of the people that is guilty of forgetting about caribou down here.
Interesting point about how the environmental factors/logging practices that lead to moose proliferation have also allowed wolves to bridge the gap and come in contact with caribou in a way they may not have in the past. Not totally sure what that means in the big picture of things, but I think it may be reasonable to conclude that at least in this situation a 2016 wolf is a different animal than a 1716 wolf.
