Webb10 apr. 2024 · The study was conducted to assess the current biodiversity in Chalan beel, Natore district, Bangladesh. Primary data were collected through stratified random sampling and analyzed through a combination of descriptive statistical and mathematical techniques. The Shannon-Weiner and Margalef richness indices were used to quantify … 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 ].

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. WebbShannon-Wiener diversity index has been used extensively in environmental studies to estimate the species richness and abundance of ecosystems. The use of the index …
