WebbThe Shannon index (H) is a measure of the information content of a community rather than of the particular species that is present. The index is as follows: H=−∑i=1Spilogpi where sis the number of species in the community (species richness) and piis the relative proportion of … Webb11 okt. 2024 · Shannon or Shannon–Weaver (or Shannon–Wiener) index is defined as H = -sum p_i log (b) p_i, where p_i is the proportional abundance of species i and b is the base of the logarithm. It is most popular to use natural logarithms, but some argue for base b = 2 (which makes sense, but no real difference). litter pearls micro crystals cat litter
