WebbShannon index (entropy). A diversity index, taking into account the number of individuals as well as number of taxa. Varies from 0 for communities with only a single taxon to high values for communities with many taxa, each with few individuals. Menhinick's richness index - the ratio of the number of taxa to the square root of sample size. WebbThe Shannon index is a mathematical tool for calculating the proportional abundance of species in a given location. This type of species abundance provides an indication of the biological diversity in that area. It is related to information entropy in that the formula Of the two concepts is identical.

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.

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. 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…

WebbSimpson index is the measure of the degree of concentration when individuals are classified into types. This was introduced by Edward H. Simpson in the year 1949.
