Equilibrium Theory of Insular Zoogeography MacArthur and Wilson (1963, 1967) Predicts that: the number of species on an island is determined by a balance between immigration and extinction, and this balance is dynamic, with species continually going extinct and being replaced through immigration.

The study of insular biogeography has contributed a major part of evolutionary theory and much of its clearest documentation. An island is certainly an intrinsically appealing study object. It is simpler than a continent or an ocean, a visibly discrete object that can be labelled with a name and its resident populations identified thereby.

The Theory of Island Biogeography Island biogeography has been a subject of considerable interest to biologists and geographers since the time of Darwin, Wallace, and the less well-known Hooker. Hooker explored islands in the South Atlantic and South Pacific. Darwin and Wallace are more important in our current thinking, since these two were pioneers in the development of the theory of evolution.

Theory of Island Biogeography. The Theory of Island Biogeography is determined by two factors. The first is the effect of distance from the mainland. The mainland is where new immigrant species originally inhabited. The second is the effect of island size. These two factors establish how many species an island can hold at equilibrium.

AN EQUILIBRIUM MODEL The impoverishment of the species on remote islands is usually explained, if at all, in terms of the length of time species have been able to colonize and their chances of reaching the remote island in that time. According to this explanation, the number of species on islands grows with time and, given enough time, remote

Theory of Island Biogeography. The Theory of Island Biogeography is determined by two factors. The first is the effect of distance from the mainland. The mainland is where new immigrant species originally inhabited. The second is the effect of island size. These two factors establish how many species an island can hold at equilibrium.

Criticism. Several studies have disputed the underlying assumptions in MacArthur and Wilson’s theory of island biogeography: specifically, the interchangeability of species and islands, the independence between immigration and extinction, and the insignificance of non-equilibrial processes.
