Island biogeography
The study of the relationship between island area and species number. This idea has also been applied to isolated areas of habitat in continental areas which are effectively islands for many species. The extent to which habitat fragmentation may lead to extinction of species can be predicted from the relationship between number of species and island area. (source: WCMC) Background from Wikipedia The study of island biogeography is a field within biogeography that attempts to establish and explain the factors that affect the species diversity of a particular community. In this context the island can be any area of habitat surrounded by areas unsuitable for the species on the island; not just true islands surrounded by ocean, but also mountains surrounded by deserts, lakes surrounded by dry land, forest fragments surrounded by human-altered landscapes. The field was started in the 1960s by the ecologists Robert MacArthur and E.O. Wilson, who coined the term theory of island biogeography, as this theory attempted to predict the number of species that would exist on a newly created island.
