Minnesota Black Bear Research

The Minnesota Department of Natural Resources (DNR) conducts research on the Minnesota black bear in order to better understand the bear population, behavior, and research conservation. This research is vital to the black bear population in Minnesota. The Minnesota DNR has graciously allowed researchers from the University of Minnesota's Visible Heart Laboratory and Medtronic Inc. to accompany them in the field to gather additional information. The goal of the Visible Heart Lab's research is to develop an understanding of the behaviors and physiological parameters of these amazing animals and develop translational applications to human medicine.
