Caribbean islands, despite comprising only 0.15% of the Earth’s area, account for at least 10% of the world’s recorded bird extinctions, 40% of mammal extinctions and more than 60% of reptile ...
The Living Planet Index, which draws on data from 35,000 population trends and 5,495 species shows Latin America and the Caribbean have seen the fastest declines in wildlife, with average wildlife ...

Many large animals on islands have been hunted to extinction by humans. A well-known example is the dodo , once found on the island of Mauritius . [ 15 ] It evolved to become large, flightless and docile, and was subsequently driven to extinction by humans and introduced predators.
Other such areas include the eastern coasts of Asia and Africa, northern coasts of South America, and the Caribbean Sea and its associated islands. [ 7 ] Regions of un sustainable agriculture or unstable governments, which may go hand-in-hand, typically experience high rates of habitat destruction.
The Theory of Island Biogeography has its roots in Wilson's work on the ants of Melanesia.MacArthur synthesized Wilson's ideas about competition, colonization and equilibrium into a simple graphical representation of immigration and extinction curves, from which one can determine the equilibrial species number on an island. [3]
The rate of extinction once a species manages to colonize an island is affected by island size; this is the species-area curve or effect. Larger islands contain larger habitat areas and opportunities for more different varieties of habitat. Larger habitat size reduces the probability of extinction due to chance events.
In this region, Island Conservation works primarily in Puerto Rico, The Commonwealth of The Bahamas, and the Dominican Republic. In May 2012, Island Conservation and the Bahamas National Trust worked together to remove invasive house mice from Allen Cay to protect native species including the Allen Cays rock iguana and Audubon's shearwater.
