WebbSpecies diversity was calculated using three different indices on sets of real and artificial data. Each index was analyzed to determine its relationship to the two component parts of diversity, richness and evenness. Shannon's information formula, H' = C~pi log2 pi, is found to be linearly related to evenness and to the log2 of the number of ...

Webb9 feb. 2024 · Hill diversity comprises a spectrum of diversity metrics and is based on three key insights. First, species richness and variants of the Shannon and Simpson indices are all special cases of one general equation. Second, richness, Shannon and Simpson can be expressed on the same scale and in units of species.
