Wolves on Isle Royale switch from moose to beavers. Will it alter ecosystem?
From BridgeMI.com:
Researchers looked at the location of wolves on Isle Royale relative to the location of known active beaver lodges. In the absence of large predators, the beaver population boomed but has fallen drastically since the translocation of wolves onto the island. As moose grow stronger during summer and fall, wolves appear to shift their attention to beavers.
