Log S = Log c + z Log A

Distance from Mainland: Fewer Species

Immigration & Extinction: I(S), E(S)

Predicting Equilibrium Species Number

Relative turnover rates tend to be lower for organisms with longer generation times

Immigration and extinction rates (species/year) of animals and plants on Rakata

Colonization curves for various animal taxa in the Krakatau Islands

Simberloff: Arthropods/Mangrove Islands

Modifications of MacArthur and Wilson’s equilibrium theory of island biogeography

Harmonic

Disharmonic

Species with low resource requirements are disproportionately more common on islands

Incidence functions for various bird species in the Bismarck Archipelago

Taxonomic endemicity
