Island Size and Distance: Predicting Extinction and Colonization Rates in Island Biogeography
Two islands (A and B) located approximately 180 km and 100 km respectively from the mainland. Island A is 160 sq. km, while Island B is 220 sq. km in […]

The Balance of Colonization and Extinction: The Core of MacArthur and Wilson’s Equilibrium Model of Island Biogeography
The equilibrium model of island biogeography proposed by MacArthur and Wilson assumes that the number of species on an island represents a balance between (1) resource consumption rate and predation […]

How Island Size and Distance Affect Immigration and Extinction: Insights from Island Biogeography Theory
The above graph illustrates two lines that represent the immigration and extinction rates for an island based on its distance from mainland (solid line) and its size (dotted line). Which […]

Decoding Island Size and Isolation in MacArthur and Wilson’s Island Biogeography Model
A researcher working on island biogeography mapped how isolation-controlled immigration (l), and area-controlled extinction (E), will act on number of species present on the islands. He forgot to label the […]
