The Theory of Island Biogeography (book)

The Theory of Island Biogeography, developed by ecologists Robert MacArthur and Edward O. Wilson, explains how species richness varies on islands based on their size and distance from the mainland. Larger islands tend to support more species due to their greater habitat variety and resources, while islands closer to the mainland receive more species through migration. The theory also addresses the balance between species immigration and extinction, influencing biodiversity. It helps us understand not only island ecosystems but also fragmented habitats on continents, highlighting the importance of conservation in maintaining biodiversity.
