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. Webb14 mars 2024 · The Shannon index in home garden was 4.078 whereas that was 3.13 low lands and 4.29 in the upland. The Shannon Wiener index along with effective number of species, revealed a high level of diversity of crop species with even distribution in the study area. The crop diversity and food self-sufficiency months were positively correlated.

Redundancy analysis (RDA) revealed a relatively strong relationship between the species diversity and soil environmental factors.

WebbTo measure species evenness, the Pielou index was used, which compares the actual diversity values using Shannon-Wiener index to the maximum diversity value. The Pielou index value ranges from 0 to 1, the more the variation in abundance between the different taxa within the community the lower the J value and vice versa [ 33 ].
