WebbTable 1 shows that the Shannon entropy or Shannon-Wiener index is converted to effective number of species or true diversity by taking the exponential: exp (1.609) is 5.000, so the true diversity according to the Shannon entropy is also 5.000 species. Webb28 sep. 2024 · Shannon-Wiener is an index that reflects the microbial diversity in the group. It reflected the microbial diversity of each sample at different sequencing amounts. When the curve tends to be flat, it indicates that the amount of sequencing data is large enough to reflect most of the microbial information in the group.

Webb1 jan. 2000 · Abstract The Shannon-Wiener diversity index (H) has been used to characterize grooming relationships among adult female primates. To make comparisons among different groups, the value of H has been divided by the maximum value it can reach for a particular group size.
