NettetThe MacArthur—Wilson model of island biogeography is modified to provide for this effect of immigration on extinction, which we call the rescue effect. This new model predicts that when immigration rates are high relative to extinction rates, turnover rate is directly related to the distance between an island and the source of colonizing species.

In California, the distribution of serpentine soil creates patchy insular serpentine grasslands (ISGs) that serve as important habitats for several endemic plant species and therefore merits consideration for conservation.
