The island species–area relationship: biology and statistics

Web7 de jan. de 2024 · The species-area relationship is one of the oldest known and most documented patterns in ecology. It describes the general pattern of increase in species richness with increasing area of observation, but it can take on different forms and be explained by various mechanisms. Web2 de jun. de 2024 · The positive relationship between species richness and area—the species–area relationship (SAR)—is a key principle in ecology. Previous studies show large variation in the SAR across taxa collectively indicating the necessity of a taxon-focused approach to accurately evaluate biodiversity scaling patterns.
