First, species richness and variants of the Shannon and Simpson indices … WebbFor a vector of species counts x, the dominance index is defined as D = \sum_i p_i^2, D = ∑i pi2, where p_i pi is the species proportion, p_i = x_i / N pi =xi/N, and N N is the total number of counts. This is equal to the probability of selecting two individuals from the same species, with replacement. Relation to other definitions:
