Wilson and MacArthur's theory of island biogeography is based on the balance between immigration to an island and extinction of resident species. This balance determines the number of species present on an island at any given time. As the rate of immigration decreases and the rate of extinction increases, the number of species on the island will decrease. Conversely, as the rate of immigration increases and the rate of extinction decreases, the number of species on the island will increase. Thus, the theory is based on the balance between these two processes.
