Simpson's diversity index Methods: Simpson's diversity index (D) is a simple mathematical measure that characterizes species diversity in a community. The proportion of species i relative to the total number of species (pi) is calculated and squared.

For those of you who've had population genetics, you can think of the as allele frequencies and Simpson's diversity as the panmictic heterozygosity. It's the probability that any two individuals chosen at random from the community belong to different species.

Learn how to compute measures of biodiversity such as species richness (S), Simpson's index of diversity (D), Shannon-Weiner index (H) and Evenness(E). A comparison of one or all of these measures of biodiversity can illustrate changes in water quality conditions within a local community. Simpson's index of diversity:
