In actual fact, his "solo debunking study" is one of a very long academic career of studying wolves and other prey. Quoting from http://www.davemech.org/: "L. David Mech (pronounced "Meech") is a Senior Scientist with the Biological Resources Division, U.S. Geological Survey and an Adjunct Professor in the Department of Fisheries, Wildlife and Conservation Biology, and Ecology, Evolution and Behavior at the University of Minnesota. He has studied wolves and their prey since 1958, as well as several other species of wildlife."
He has a massive list of peer-reviewed publications, going back 50 years (http://www.davemech.org/publications.html), and looks exactly like every serious academic researcher I've come across.
Yet he links to OWS from his personal site and all of a sudden that's all invalidated?
