WebbShannon or Shannon--Weaver (or Shannon--Wiener) index is defined as H ′ = − ∑ i 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).

WebbThe Shannon-Wiener index is defined as is the natural logarithm of the total number of species. A value for evenness approaching zero reflects large differences in abundance of species, whereas an evenness of one means all species are equally abundant: where is the total number of species, “ ” is the number of individuals, and “ ” is the natural logarithm.

Webbcombining two years observation. The Shannon-Wiener diversity index is a heterogeneity measure that incorporates species richness and evenness (Hollenbeck and Ripple, 2007). Relative to other diversity indices, such as Simpson’s index, it is considered sensitive to the addition of rare species (Krebs, 1989). The aim of the WebbTwo of the commonly used measures of evenness are the Shannon index (H) and the Simpson index (D).
