Determinants of orchid species diversity in Latin America

Popis výsledku v původním jazyce

Area and latitude are thought to be the most important determinants of species richness. The relativenimportance of these two factors was recently tested, using data on orchid species diversity in various countriesnin the world and it was found that size of the country (or of the protected areas within the country) is a betterndeterminant of species diversity in orchids than latitude. On the other hand, literature data indicate that in manyngroups species richness is also heavily dependent on habitat diversity as expressed by the range of altitudes innthe region considered. Here we analyze the species richness data for various countries in Latin America, usingnthe above-mentioned altitudinal amplitude as a proxy. Habitat diversity played a role in tropical, but not inntemperate countries. The reason may indicate that in the temperate countries only few orchid species grow innhigher elevations, so an increase of altitudinal range of habitats there does not entail a corresponding increasenof species richness there. Thus, especially in the tropics, efforts should be directed to preservation of protectednareas in all altitudes, rather than to increase of existing reserve size only in areas that are not attractive for humanndevelopment.
