La présence d’espèces rares dans le peuplement ne modifie pratiquement pas la valeur de l’indice de diversité, contrairement à l’indice de Shannon beaucoup plus sensible.
WebbFör 1 dag sedan · The Shannon-Wiener diversity index (H’) gives more weight to rare species, while the Pielou (J) evenness indicates the uniformity of the samples. While the Simpson index (1-D) gives greater weight to the most common species, its values were consistent with those of the Shannon index ( Table III ).
