My first post on this subject disapeared! /ubbthreads/images/graemlins/mad.gif Glitches, don't ya love em.
I did some work on bear/moose mortality while in Alaska. We radio collared 50 moose calves within two days of being born and watched to see what happened. The bears zeroed in on moose calving grounds and wreaked havoc on the calves. Most calves were dead within two weeks of being born. After that, they tended to live through the summer. Come winter they got to fend off the wolves. Ah, a moose's life. Wouldn't want to be one.
Most folks think the wolves are the cause of low moose densities, but actually bears got a higher percentage.
