Recall the classic experiments assessing arthropod extinction rates in moss (Figure 46.14). If corridors are eliminated between moss patches, how does this change affect the arthropods inhabiting the moss?

Question

Quizplus · Accepted Answer

Corridors connect patches of habitat and allow for the movement of individuals between them. Eliminating corridors would reduce the ability of arthropods to move between moss patches, making them more isolated and reducing gene flow. This increases the likelihood of inbreeding depression and decreases genetic diversity, which can ultimately lead to higher extinction rates. Therefore, the extinction rates of arthropods in the moss would increase if corridors between moss patches were eliminated.
