Small island developing states (SIDS) are identified as a group of 38 United Nations (UN) Member States and 20 Non-UN Member/Associate Members that are located in three regions: the Caribbean; the Pacific; and the Atlantic, Indian Ocean, Mediterranean and South China Seas (AIMS) and are home to approximately 65 million people.
By 2100, sea level in the Caribbean is expected to rise by 1.4 m. [23] Rise in sea level could impact coastal communities of the Caribbean if they are less than 3 metres (10 ft) above the sea. In Latin America and the Caribbean, it is expected that 29–32 million people may be affected by the sea level rise because they live below this threshold.
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.
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.
