A Population of Wolves Predates a Population of Moose on Isle

question 64

Multiple Choice

A population of wolves predates a population of moose on Isle Royale, Michigan, where there are fewer wolves than moose to start. The wolves prey on the moose and eat well, allowing them to have abundant offspring. However, as the wolf population rises, the moose population drops, and over time, the wolf population begins to drop also because of the reduced availability of resources. As the wolf population drops, moose are able to better survive and reproduce, causing the moose population to rise. With this abundance of moose, the wolf population is able to rebound until their population exceeds the moose population's ability to support the number of wolves. Which population dynamic does this series of oscillations represent?

• A) Delayed density dependence
• B) Delayed density independence
• C) Extinction vortex
• D) Carrying capacity
