WebbNot entirely sure how you got -1, but let's work through it here. So the total number of organisms N in your example would be 5, and n (i) would be one; then by the formula, the diversity index is 1 - (1 (0) + 1 (0) + 1 (0) + 1 (0) + 1 (0))/ (5*4) , which simplifies to 1 - … 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…

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.
