Isle Royale wolf numbers stay dangerously low; moose on upswing

Isle Royale’s National Park’s inbred gray wolf population remains dangerously low for a third consecutive year, while the moose on which they feed have doubled during the same period – trends that could lead to long-term problems for the Lake Superior archipelago’s ecosystems, scientists said Wednesday.  Only nine wolves roam the park this winter…The study is the world’s longest of a predator-prey relationship in a closed ecosystem. “The wolves are struggling,” said Rolf Peterson, a research professor with Michigan Technological University and co-director of the study.  “There’s definitely a chance they might not last much longer.”
