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. The theory of island biogeography, developed by Robert MacArthur and Edward O. Wilson, looks to explain the differences in species diversity with island size (for example, why large islands tend to have a greater number of species of a certain category than small islands). MacArthur and Wilson proposed that the number of species found on an island can be determined by a balance between the. Equilibrium Theory of Island Biogeography (ETIB) The ETIB describes the theoretical relationship between immigration and extinction of species to islands, depending on their size and distance from the mainland or other species source. Consider the degree of isolation of the area under study.
Island biogeography equation of a circleIsland biogeography is the study of the factors affecting species diversity of . Find the equation of the straight line that has slope m=4 and passes through the Area = length times width = l x w. Circle: Area = pi times radius squared = πr2. Wilson theory of island biogeography with a student physical simulation of velop the basic MacArthur-Wilson equations for rate of change of species numbers. We solicit input from the class at large beginning with the initial circle labeled. However, much of the theory of island biogeography was built on data which came from . The graph of the basic equation would show an exponential rise in the . The open circles are points for islands relatively near New Guinea, the filled.

Insular biogeography or island biogeography is a field within biogeography that examines the . application to the field of conservation biology had been realised and was being vigorously debated in ecological circles. Habitat diversity was as or more important than size in determining the number of species protected.
