I was reading this short article about a PhD student at the University of Wyoming's research into polar bears and how they cope with less pack ice and shorter winters, when I came across a hilarious piece of methodology. It seems that the polar bears are collared for tracking purposes, and that sometimes the collars cause problems. Under the heading "When is a collar too tight, and what should be done if a tight collar is observed?", there is this particularly evocative paragraph:
I am 100% sure that the biologist who is theoretically going to "attempt to remove the collar from the bear" -- at this point an enraged, bloody, obese polar bear -- is a PhD student.
