What is Relaxation of Species

Actual islands, surrounded by the ocean, are generally species-poor. This is true no matter how distant or remote an island is from a land mass. It is believed that the relative small size of an island inhibits diversity. The relaxation of species, a term for their disappearance, happens over time. Relaxation is explained by the experts as the result of smaller areas and smaller populations making species vulnerable to happenstance. The re-colonization of a species on an island is nearly impossible.
