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… WebMar 1, 1973 · The diversity of the prey consumed by the species evaluated was calculated using the effective number of species or Hill numbers (q0, q1 ... Anim.
