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 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.

Consider the degree of isolation of the area under study. Insular biogeography or island biogeography is a field within biogeography that examines the factors that affect the species richness and diversification of isolated natural communities. The theory was originally developed to explain the pattern of the species–area relationship occurring in oceanic islands. In a variety of taxa on many different island systems (Table ), z-values generally range from about to about The z-value is the exponent in the equation. S = CA z (1) where S is the number of species, C is a constant that varies between taxa and from place to place, and A is the area of the island(s) concerned. 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. A modified version of the classical island biogeography model proposed by MacArthur and Wilson () is depicted above. The model considers the interaction of two main parameters, colonization and extinction, and then considers island size and distance from mainland as predictors of the species richness found on each island. Island Biogeography Laboratory 1 Learning Goals At the end of this laboratory, the students should be able to: Describe the species{area curve and the equilibrium model of island biogeography; Use the equilibrium model of island biogeography to predict both (a) the equilibrium number of species on an island and (b) the equilibrium species. Methods: MacArthur and Wilson proposed the "equilibrium model of island biogeography" in the ís. The basic idea of the model is that the number of species on an island is determined by the immigration of new species and the extinction of species already present; when these two rates balance one another, the species number is at equilibrium. In this lesson, you will learn about island biogeography, which is the species composition on an island. Because island habitats are so isolated and unique, the theory of island biogeography.
