Robert H. MacArthur (1930-1972) was an influential American ecologist known for his pioneering work in the field of ecology and biogeography. He is perhaps best recognized for his contributions to the development of the theory of island biogeography, which he co-developed with Edward O. Wilson. This theory explains the ecological and evolutionary dynamics of island species, suggesting that the number of species on an island is determined by the balance between immigration and extinction rates.
