WebbEl índice de Shannon-Wiener (H) procede de la teoría de la información y mide la diversidad como: H = -Σpi.ln (pi) pi = ni /N Donde ni es el número de individuos de la especie i y N es la abundancia total de las especies. 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… WebbQuestion: The Shannon Index is a measurement used to compare diversity between habitat samples. This comparison can be between two different habitats or a comparison of one habitat over time. The actual formula for the Shannon-Weiner Diversity Index is: H=−∑p1lnpi Where pi = the proportion of individuals of species i. theo theater oberzeiring
