Which of the following is a correct statement about MacArthur and Wilson's island equilibrium model?
A) As the number of species on an island increases, the emigration rate decreases.
B) Competitive exclusion is less likely on an island that has large numbers of species.
C) Small islands receive few new immigrant species.
D) Islands closer to the mainland have higher extinction rates.

Question

Quizplus · Accepted Answer

C) Small islands receive few new immigrant species. According to MacArthur and Wilson's island equilibrium model, the rate of species immigration is influenced by the distance of an island from the mainland, with more distant islands receiving fewer new immigrant species. This model also suggests that smaller islands have lower immigration rates because they present a smaller target area for dispersing organisms.
