Describe the predator-prey relationship between the moose and wolves of Isle Royale. What other factors influence these two populations?
What will be an ideal response?
"Fewer wolves represent low environmental resistance for the moose, so the moose population increases. Then, the abundance of the moose represents optimal conditions (low environmental resistance) for the wolves, so the wolf population increases. More wolves means higher predation on the moose (high environmental resistance); again the moose population falls. The decline in the moose population is followed by a decline in the wolf population because now there are fewer prey (high environmental resistance for the wolves)."
Other factors also influence these two populations. Examples given in the text include changes in weather (deep snow) that affected the moose population, deep freezes, parasites, and other natural enemies of both populations.
