Island Biogeography Home
Why do many more species of birds occur on the island of new guinea than on the island of bali?one answer is that new guinea has more than fifty times the area of bali, and numbers of species ordinarily increase with available space. 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. under either name it is now used in reference to any ecosystem (present or past) that. A modified version of the classical island biogeography model proposed by macarthur and wilson (1963) 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. Theory of island biogeography. island biogeography (also called insular biogeography) provides some of the best evidence in support of natural selection and the theory of evolution. the term describes an ecosystem that is isolated by being surrounded by different ecosystems. for the purposes of this theory, an island is defined as more than just a piece of land surrounded by water. Island biogeography . biogeography is the study of the geographic location of a species. island biogeography is the study of the species composition and species richness on islands.

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.
