The species-area-energy relationship

Original language description

Area and available energy are major determinants of species richness. Although scale dependency of the relationship between energy availability and species richness (the species-energy relationship) has been documented, the exact relationship between thespecies-area and the species-energy relationship has not been studied explicitly. Here we show, using two extensive datasets on avian distributions in different biogeographic regions, that there is a negative interaction between energy availability andarea in their effect on species richness. The slope of the species-area relationship is lower in areas with higher levels of available energy, and the slope of the species-energy relationship is lower for larger areas. This three-dimensional species-area-energy relationship can be understood in terms of probabilistic processes affecting the proportions of sites occupied by individual species. According to this theory, high environmental energy elevates species´ occupancies, which depress

Vztah mezi počtem druhů, plochou a energií

Czech description

Existuje negativní interakce mezi plochou a dostupností energie v jejich vlivu na druhové bohatství: vztah mezi plochou a počtem druhů je méně strmý v oblastech s vyšší produktivitou prostředí a vztah mezi produktivitou a druhovým bohatstvím je méně výrazný pro větší plochy. Druhově bohaté oblasti jsou tak v jistém smyslu homogennější co se týče druhového složení než oblasti chudé.
