WebbShannon wiener index (Shannon-Weiner index) is used to describe the disorder and uncertainty of individual species. The higher the uncertainty, the higher the diversity. WebbThe Shannon evenness index, abbreviated as SEI, provides information on area composition and richness. It covers the number of different land cover types (m) observed along the straight line and their relative abundances (P i ). It is calculated by dividing the Shannon diversity index by its maximum (h (m)).

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 … WebbThe Shannon entropy quantifies the uncertainty (entropy or degree of surprise) associated with this prediction. It is most often calculated as follows: where pi is the proportion of characters belonging to the i th type of letter in the string of interest.

Webbinterpretation is not used any longer. As a matter of fact, all three variants, log2, natural log and log10 are used, and all functions are called Shannon (or Shannon-Wiener, or Shannon-Weaver) index. The Shannon index has been a popular diversity index in the ecological literature, where it is also known as Shannon's diversity index, Shannon–Wiener index, and (erroneously) Shannon–Weaver index. The measure was originally proposed by Claude Shannon in 1948 to quantify the entropy (hence Shannon entropy, related to Shannon information content) in strings of text. The idea is that the more letters there are, and the closer their proportional abundances in the string of inter…
