The Theory of Island Biogeography is a 1967 book by Robert MacArthur and Edward O. Wilson. It is widely regarded as a seminal piece in island biogeography and ecology. The Princeton University Press reprinted the book in 2001 as a part of the "Princeton Landmarks in Biology" series.


Biogeography was stuck in a "natural history phase" dominated by the collection of data, the young Princeton biologists Robert H. MacArthur and Edward O. Wilson argued in 1967. In this book, the authors developed a general theory to explain the facts of island biogeography. The theory builds on the ...


The Theory of Island Biogeographywas never intended as the last word on the subject. Instead, MacArthur and Wilson sought to stimulate new forms of theoretical and empirical studies, which will lead in turn to a stronger general theory. Even a third of a century since its publication, the book continues to serve that purpose well.


THE ECOLOGY OF ISLAND COMMUNITIES The Equilibrium Theory of lsland Biogeography A decade ago, Preston (72) and MacArthur & Wilson (59, 60) revolutionized biogeography with the suggestion that the biota of any island is a dynamic equilib-rium between immigration of new species onto the island and extinction of species


What Is the Island Biogeography Theory? The theory of island biogeography states that the number of species found on a particular, undisturbed island is determined solely by the number of species immigrating to the island and by extinction rates. The theory also states that isolated species may follow evolutionary routes that are different than ...


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.


The Equilibrium Theory of Island Biogeography (ETIB) revolutionizes the way in which biogeographers and ecolo-gists viewed island ecosystems. Prior to the ETIB was the static theory of islands (Dexter 1978), which hypothesizes that island community structures remain relatively con-stant over geological time. The only mechanism for biologi-


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.


Robert H. MacArthur and Edward O. Wilson's The Theory of Island Biogeography, first published by Princeton in 1967, is one of the most influential books on ecology and evolution to appear in the past half century. By developing a general mathematical theory to explain a crucial ecological problem--the regulation of species diversity in island populations--the book transformed the science of .....
