Island ecology is the study of island organisms and their interactions with each other and the environment. Islands account for nearly 1/6 of earth’s total land area, [1] yet the ecology of island ecosystems is vastly different from that of mainland communities.
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. For example, it is known that pygmy mammoths evolved from normal mammoths on small islands.
Larger islands with diverse ecological niches encouraged floral and faunal adaptive radiation, whereby multiple species evolved from a common ancestor, each species adapted to a different ecological niche; the various species of Hawaiian honeycreepers (Family Drepanididae) are a classic example. Other adaptations to island ecologies include ...

Some endemic tree species mark niche ecological islands. One example is the rare Torrey pine (Pinus torreyana), which is only native to the coastal bluffs in Torrey Pines State Natural Reserve near San Diego, and off the coast on Santa Rosa Island. [4]
Whakaari / White Island, an island reserve. The Department of Conservation and private trusts operate ecological islands as protected habitats for endemic and native New Zealand species. Island reserves include 50 offshore islands that are nature reserves and hundreds of other islands that the Department of Conservation manage. [28]
The following is a list of marine ecoregions, as defined by the WWF and The Nature Conservancy. The WWF/Nature Conservancy scheme groups the individual ecoregions into 12 marine realms, which represent the broad latitudinal divisions of polar, temperate, and tropical seas, with subdivisions based on ocean basins.
