This is equal to the probability of selecting two individuals from the same species, with replacement. Relation to other definitions:

When diversity indices are used in ecology, the types of interest are usually species, but they can also be other categories, such as genera, families, functional types, or haplotypes. The entities of interest are usually individual plants or animals, and the measure of abundance can be, for example, number of individuals, biomass or coverage. In demography, the entities of interest can be people, and the types of interest various demographic groups. In information science, the enti… WebbShannon 's entropy index is a measure of the entropy, that applies to any numerical data, developed by Claude Shannon in the 1940s.
