Question

Quizplus · Accepted Answer

The equilibrium model of island biogeography states that the diversity on islands is determined by a balance between immigration and extinction. More specifically, the number of species on an island depends on the rates at which new species immigrate to the island and existing species go extinct. The model predicts that larger islands and islands closer to mainland sources of species will have higher immigration rates and lower extinction rates, resulting in higher overall diversity.
