(Phys.org)—A team of researchers affiliated with several institutions in the U.S. has found that warming in Alaska has sometimes caused the Kodiak bear to switch to eating elderberries during salmon spawning periods instead of eating salmon. In their paper published in Proceedings of the National Academy of Sciences, the group describes their multi-pronged study of the impact that seasonal changes occurring on the Kodiak Archipelago are having on the bears that live there.
