A few days after Fat Bear Week wrapped up, here’s a pretty amazing reminder that there’s much more to Alaska’s brown bears than their impressive size. 🐻
APU graduate student and researcher Beth Rosenberg is the co-author of a new study developing AI technology that can identify individual brown bears in the wild, even as their appearance changes throughout the year. The technology could help researchers better understand bear behavior, populations and movement without relying on collars, tags or other invasive methods.
Rosenberg and researchers at EPFL trained the system using more than 72,000 images of 109 individual brown bears from Alaska’s McNeil River State Game Sanctuary. Enjoy this video of a bear chasing salmon from this summer!
From Fat Bear Week champions to cutting-edge wildlife research, Alaska’s bears are giving us plenty to learn from. 🐻
