ABSTRACT
Isle Royale, which sits in Lake Superior and belongs to the United States through the state of Michigan, hosts the most-studied predator–prey animal relationship in the history of the Great Lakes watershed. The island sits in the middle of the largest freshwater lake on the continent, it is easily accessible by boat, ski plane, or seaplane unless the weather is terrible. The researchers who first took extended looks at the moose on Isle Royale included Adolph Murie, who has been called the first scientist to study wolves in their natural habitat. National Park Service biologist James E. Cole was sent to Isle Royale from his regular assignment at Rocky Mountain National Park in Colorado to do a wolf count in 1952. He and park ranger Roger Hakala located four wolves during the winter. In 1958, some researchers began a close study of the predator–prey relationship between wolves and moose that continues into the twenty-first century.
