Multiple methods needed to control destructive Great Lakes invader.
They’ll soon be here in the Great Lakes basin, a crucial stop on a 12,400 flight from Canada to the Amazon.
Researchers say inbreeding is likely inevitable, despite efforts to increase genetic diversity in the island’s wolves.
Six of the animals were transferred from another Lake Superior island in a bid to control Isle Royale’s moose population and restore its forests.
As the Upper Peninsula reaches its capacity for grey wolves – there are more than 650 now — chances increase that some will migrate south across the ice to the northern Lower Peninsula, which currently has no wolves but plenty of suitable habitat for denning.
What are moose poop and pee good for? That’s a science question, and research on Isle Royale and in northeast Minnesota shows moose effectively transfer nitrogen — an essential nutrient for forest health — from the aquatic plants they chow down on to fertilize the forest.
Others dispute that it is inevitable.
A new study predicts where the red swamp crayfish could next pop up on the Great Lakes. That could help state agencies prevent the spread of the fast reproducing invader that alters entire ecosystems.
