Quizplus · Accepted Answer

The wolf-moose population cycles on Isle Royale are also correlated with the population of fir trees. The health and abundance of these trees can affect the moose population, as they are a significant source of food, especially in winter. This, in turn, can affect the wolf population, as wolves prey on moose.
