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. WebbFormula Matematicamente, calculamos o índice de Shannon por meio da seguinte expressão: H ‘ = – Σ pi ln pi Na expressão do índice, a variável pi representa a abundância proporcional da espécie i, calculada como o peso seco da espécie, dividido, por sua vez, pelo peso seco total da amostra.
