Predation by brown bears was the greatest cause of mortality. Brown bears averaged 1 calf and 1 adult moose kill/11.7 and 43.7 bear-days, respectively, during late May-late June, while black bears averaged 1 calf moose kill/40 bear-days during the same period. No adult mosoe were killed by black bears. There were no statistically significant differences (<em>P</em> &gt; 0.05). in predation rates among sexes, ages, or family classes of either brown or black bears. Predation rates were highly variable among individual bears.</p> ER -
