Insular biogeography [1] 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.
Thorson's rule (named after Gunnar Thorson by S. A. Mileikovsky in 1971) [1] is an ecogeographical rule which states that benthic marine invertebrates at low latitudes tend to produce large numbers of eggs developing to pelagic (often planktotrophic [plankton-feeding]) and widely dispersing larvae, whereas at high latitudes such organisms tend to produce fewer and larger lecithotrophic (yolk ...
In Chapters 2 and 3, MacArthur and Wilson postulate that insular species richness depends on island size and isolation from source regions. The authors present an equilibrium model that is based on the following concept: when there is an addition of the number of species on an island, the island's immigration rate of new species will decrease ...

Island gigantism, or insular gigantism, is a biological phenomenon in which the size of an animal species isolated on an island increases dramatically in comparison to its mainland relatives.
Garganornis ballmanni, a very large fossil goose from the Gargano and Scontrone islands of the Late Miocene. Foster's rule, also known as the island rule or the island effect, is an ecogeographical rule in evolutionary biology stating that members of a species get smaller or bigger depending on the resources available in the environment.

MacArthur was a professor at the University of Pennsylvania, 1958–65, and professor of biology at Princeton University, 1965–72.He played an important role in the development of niche partitioning, and with E.O. Wilson he co-authored The Theory of Island Biogeography (1967), a work which changed the field of biogeography, drove community ecology and led to the development of modern ...
