Graduate students contribute to study on effect of drones on bears

CBS graduate students Jessie Tanner (Plant Biological Sciences), John Vincent and Lealand Werden (Ecology Evolution and Behavior) contributed to a study on the impact of unmanned aerial vehicles, or drones, on bears. The study, published in Current Biology, found that despite a calm demeanor when in the presence of UAVs, bears’ heart rates soar, a sign of acute stress. The study was led by Mark Ditmer, a post-doctoral researcher in the Department of Fisheries, Wildlife and Conservation Biology (CFANS).
