Equilibrium Theory of Island Biogeography and Ecology

Annual Review of Ecology and Systematics, 1974
Department of Biological Science, Florida State University, Tallahassee, Florida 32306THE BIOLOGICAL IMPORTANCE OF ISLANDSOceanic islands and archipelagoes are intrinsically important to biologists; 5% ofthe land surface of the earth is insular, and if South America, which has been anisland throughout most of its existence, is included the figure rises

Independent Discovery of the Equilibrium Theory of Island Biogeography

Ecology, 1989
A correlation of this kind [between number of species and logarithm of area of island] is as interesting as it is unexpected, for it suggests the existence of an equilibrium valuefor the number of species in a given island, a value which acts as a limit to the size of the fauna. The processes which determine the equilibrium value for an island of given

Island Biogeography Theory and the Island Rule in Orchid Bees in Panama

Journal of Biogeography
ABSTRACTAimThe study of the theory of island biogeographic (TIB) has focused mainly on plants and vertebrates, with support for the predictions that species richness decreases with distance from the mainland and increases with island size. However, less work has been done on invertebrates. Similarly, the study of the island rule has been studied mainly

The Equilibrium Theory of Island Biogeography: Fact or Fiction?

Journal of Biogeography, 1980
The development of the equilibrium theory of island biogeography and its basic concepts are outlined. Studies purporting to validate the theory are critically examined, and it is concluded that there is little support for its tenets. The application of the theory to nature conservation and ecology is therefore premature.

Myxomycetes within the scope of the Island Biogeography Theory

MycoAsia
Myxomycete data compiled from twelve different investigations on oceanic islands in different parts of the world were analyzed. The objective was to contextualize the potential application of some theoretical insights on the interpretation of the mechanisms responsible for the distribution of myxomycetes.

The diversity of freshwater snails in view of the equilibrium theory of island biogeography

Oecologia, 1975
The distribution and diversity of Danish freshwater snails is discussed in the light of MacArthur and Wilson's theory of island biogeography. Species-area curves for 86 eutrophic and oligotrophic ponds and lakes are made and the variance to mean ratios of species numbers in lakes of identical sizes calculated.

Islands within the sea: the theory of coralline boulder biogeography

1993
Boulders of coralline rubble are common substrates on tropical ocean shelves which support a variety of invertebrate life as isolated islands. In this study we attempted to correlate boulder depth, porosity, and volume to the species richness and diversity within these island habitats. We found positive correlations between boulder volume and number of

Island Biogeography Theory of coevolution in pollination networks

Abstract Island ecosystems have been pivotal in understanding community assembly and biodiversity, from the competing roles of colonization and extinction, to the influence of spatial structure, species interactions, and evolutionary processes.

On the semiotic dimension of ecological theory: The case of island biogeography

Biology & Philosophy, 1986
The Macarthur-Wilson equilibrium theory of island biogeography has had a contradictory role in ecology. As a lasting contribution, the theory has created a new way of viewing insular environments as dynamical systems. On the other hand, many of the applications of the theory have reduced to mere unimaginative curve-fitting.
