Tracking Grizzlies by GPS (IMAGE)
Caption
Chad Dickinson, a biological science technician with the Interagency Grizzly Bear Study Team, fits a Global Positioning System collar on a male grizzly bear in Yellowstone National Park. Christopher Peck and colleagues used GPS telemetry data from males like this one to predict the behavior and habitat selection of bears exploring landscapes outside the Greater Yellowstone Ecosystem, on journeys that could bring them into contact with breeding grizzly populations in the Northern Continental Divide Ecosystem, and vice versa. They report their results in "Potential paths for male-mediated gene flow to and from an isolated grizzly bear population" in the journal Ecosphere.
