About John Pastor

I am now Professor Emeritus of Biology at the University of Minnesota Duluth and past Co-Chair of the Natural History Section of the Ecological Society of America.

My research interests include the structure and function of northern ecosystems, response of forests to climate change, forest-wildlife interactions, applications of mathematics to ecological problems, and scientific illustration. I taught Mathematical Ecology, Ecosystems Ecology, Animal Behavior, and Biological Illustration, among other courses.
