Jerod A. Merkle

Hello! Welcome to my professional page. I have a B.S. in Wildlife Biology from the University of Arizona (2006), a M.S. in Wildlife Biology from the University of Montana (2011), and a Ph.D. in Biology from Université Laval, Québec (2014). I am a quantitative wildlife ecologist with broad interests in understanding how the movement of animals scales-up to population- and landscape-level ecological processes. My research is collaborative in nature and links ecological theory with empirical data to make scientific breakthroughs while providing useful knowledge for on-the-ground challenges in wildlife conservation and management. I have contributed to research on gray wolves, coyotes, black bears, bison, mule deer, elk, bighorn sheep, moose, and caribou. Currently, I am working on a number of projects related to the ecology and conservation of animal movement and migration.
