Island Biogeography Theory

Ecology & Ecosystems 1967

Discoverers: Robert MacArthur, Edward O. Wilson

Overview

Mathematical theory predicting species richness on islands based on island area and distance from the mainland, balancing immigration and extinction rates.

Significance

Provided a quantitative framework for understanding species diversity patterns and became foundational to conservation biology and reserve design.

Methodology

Mathematical modelling of species equilibrium combined with experimental defaunation of mangrove islands in the Florida Keys.
