Suppose the rate of plant growth on Isle Royale supported an equilibrium moose population of 380 moose. In this scenario, there are no wolves present, and the environment is stable. One day, 200 additional moose arrive on the island. What would you predict the moose population to be 30 years later? PLEASE ENTER YOUR ANSWER AS A NUMBER!!!!
Solution
The wolves and moose of Isle Royale have been studied for more than five decades. This research represents the longest continuous study of any predator-prey system in the world.
The most important events in the chronology have been essentially unpredictable. In 1980 the wolf population crashed when humans inadvertently introduced a disease, canine-parvovirus. In 1996, the moose population collapsed during the most severe winter on record and an unexpected outbreak of moose ticks. In the late 1990s, intense levels of inbreeding among wolves were mitigated when a wolf immigrated from Canada. In response, the wolf population generally increased throughout the early 21st century, despite declining moose abundance. For a more detailed interpretation of this graph,
