The Wolf and the Moose: Natural Enemies That Need Each Other. Scientific American. By Adam Hadhazy.
This is about the 50-year study of moose and wolves on Isle Royale National Park in Lake Superior. The wolves have not wiped out the moose despite the island being a very simple ecosystem, and in fact should the wolves perish, the moose population will be destroyed by overpopulation.
External environmental effects are creeping onto Isle Royale, and I would not be surprised if these two species do vanish in the near future.
