News Update 3: In other Great Lakes news, scientists at Michigan Technological University are concerned global warming is causing stress on moose and wolves at Isle Royale National Park. The moose have been there more than a century, after several swam to the island from the mainland in 1900. The wolves followed later, crossing a rare ice bridge around mid-century. The wolves feed on the moose, but the moose have been thinner of late and both populations seem to be down. (Sources: Greenwire and mlive.com.)
