Subspecies - populations of a species that occur in different geographic areas and differ from one another in some characteristics. Genetic diversities - the varieties of dna that present among individuals within species, subspecies and populations. Species diversity - the number and the variety of species in a particular region. Species richness - the number of species in a particular area. Factors that drive species richness: spatial factors: area size, proximity, fragmentation and isolation, climatic factors: productivity and predictability, historical factors: evolutionary time. Extinction- the rate at which species go extinct on an island. Some areas on earth remain little explored: many species are tiny and easily overlooked.
