Why are moose populations declining? http://michiganradio.org/post/why-are-moose-populations-declining <p>All across North America, something is happening to the moose.</p><p>From British Columbia to New Hampshire, moose populations are thinning out, and no one has been able to point to a good, clear reason why.</p><p>For the status of moose here in Michigan, we turned to Rolf Peterson, Professor at Michigan Technological University.

Romeo dies in an old mine: How three Isle Royale wolves died http://michiganradio.org/post/romeo-dies-old-mine-how-three-isle-royale-wolves-died <p>In the last year, seven wolves on Isle Royale died. <a href="http://www.michiganradio.org/post/video-isle-royale-wolves-hanging-their-teeth?nopop=1">The total population is now down to nine wolves</a>.<br /><br /> That&#39;s the lowest number recorded by researchers who have been studying the Isle Royale wolf population for the last 54 years. It&#39;s the longest continuous predator-prey study in the world.<br /><br /> <a href="http://www.michiganradio.org/topic/lessons-isle-royales-wolves-and-moose">When Rebecca Williams and I visited Rolf Peterson on Isle Royale last month</a>, we asked him about the die-off.<br /><br /> He told us they didn&#39;t know what happened to them, &quot;but we will know,&quot; he said.<br /><br /> Well, now they know how three of the seven wolves died. One was a young female wolf.

And if you heard <a href="http://michiganradio.org/post/watching-lives-wolves-and-moose-unfold-isle-royale">yesterday&#39;s report from Rebecca Williams</a>, it really does <em>sound</em> gross.</p><p>The wolf-moose research project on Michigan&#39;s Isle Royale National Park is in its 54th year.</p><p>A big chunk of their research goes into tracking down dead moose - bones and carcasses - around the island.</p><p>From these remains the researchers can pick apart the status and overall health of the moose population. And understanding moose is important to wolf research, since the wolves eat the moose.</p><p>It&#39;s like understanding the overall quality and quantity of food available at the grocery store. If there&#39;s good, abundant food available, you&#39;d expect things to be good. If not, well - you get the picture.</p><p>When Rebecca Williams and I arrived at the Daisy Farm campground on Isle Royale, we were met by Rolf Peterson in his boat.</p><p>He said he&#39;d just heard of a dead moose on Caribou Island and asked whether we would like to go see it with him.</p><p>A stroke of luck. We&#39;d traveled by plane, car, and boat to get here, and here was our chance to see Peterson in action.</p><p>Here&#39;s a video of our trip with him. Is ripping the skull off a dead moose gross? I didn&#39;t think so, but you can be the judge.</p><p>http://www.youtube.com/watch?v=AlRSoJCX9cY&amp;feature=em-uploademail</p><p>So, what did you think?
