Species accumulation curve

Description

One index of diversity is species richness i.e. total number of species of a taxon present in a locality. To estimate richness, it is convenient to go on counting randomly selected individuals and recording their species names. An accumulation curve has total number of individuals or quadrats on X-axis and accumulated number of species on Y axis.
