Endemism

 
 
Penulis: Dewi M. Prawiradilaga
Endemic taxa are those restricted to a specified geographical area. Therefore, the concept is a relative one; the patterns, correlates, and causes of endemism will vary according to the size and location of the geographical area, as well as the taxonomy and phylogenetic relatedness of the assemblage under consideration. At a global scale, all taxa are endemic and there is relatively little to say on the topic. Most research has focused on species that are endemic to relatively small areas. In this sense, endemism is best viewed as a form of rarity, that is, range-restricted rarity. This article presents biogeographical, evolutionary, ecological, and conservation perspectives on endemism and discusses generalizations regarding the patterns, correlates, and causes of species-level endemism in relatively small areas. Categories Endemics may be categorized according to their spatial distribution, inferred evolutionary age, affinities, and local abundance.
