The theory of island biogeography is based on the concept that a stable number of species is reached when immigration balances extinction. This theory, developed by Robert MacArthur and Edward O. Wilson, explains how the size and distance of islands from a source of colonizing species affect species richness and diversity. It posits that as the number of species on an island increases, the rate of immigration decreases and the rate of extinction increases, leading to an equilibrium where these rates balance out.
The theory of island biogeography is based on the concept that
