Shannon weaver index formula
http://www.thejaps.org.pk/docs/v-23-2/23.pdf WebbL' indice di Shannon-Wiener H' è un indice di diversità usato in statistica nel caso di popolazioni con un numero infinito di elementi. dove p j è la proporzione della j-esima specie (Σ j p j = 1) e s è il numero delle specie. Dividendo H' con il valore massimo possibile H' max =log e (s), si ottiene un indice compreso tra 0 e logaritmo di k.

Truth is ever to be found in simplicity, and not in the multiplicity and confusion of things. ― Isaac Newton. WebbShannon's diversity index H' = Σpi log2 pi was calculated for 267 breeding bird censuses. The index was resolved into its components, species richness and relative abundance, to determine which components played a larger role in the determination of diversity patterns.
