WebbShannon evenness index (Shannon's equitability index) is a pure diversity index, independent of species richness. It measures how evenly the microbes are distributed in a sample without considering the number of species. Values can range from zero to one: from high dominance of a single species to perfectly equal abundances across all species.

Webb1 feb. 2003 · The Shannon index belongs to the first of three general categories used by Magurran [ 13] to group the various diversity measures. These are species richness indices, indices based on the proportional abundances of species (evenness/dominance measures), and species abundance models. Webb1 jan. 2024 · The Shannon entropy index is defined as: (8.1) H d = − ∑ i = 1 n p i ln p i where pi is the proportion of individuals of the i -th species in the community, and n is the number of species in the community, or species richness, as explained previously.

WebbIn ecology, alpha diversity (α-diversity) is the mean species diversity in a site at a local scale. The term was introduced by R. H.
