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 ]. WebbShannon's (H') regression: y =13.039 x -- 5.316, r = 0.937 Note the curvilinear correlation between the number of species and each diversity index. Transformations of these same data showed that if Shannon's diversity val-ues were plotted against 10g2 of species richness, the plot was linear (Fig. 2). Simpson's index expresses the probability ...

WebbTo determine the diversity of plankton and benthos communities, the following calculation formula is used: (Ministry of Environment, the Republic of Indonesia No. 115/2003) where: H’ is Shannon Wiener diversity index and ni is number of individu within same species and N is total number of individu species found. Tabel 2. Webbwhile other species occurred together (such as Humulus japonicus and Phragmites australis) at sites B (Shannon-Wiener index; H B =0.309) and C (H C =0.299). Similar to the species diversity, genetic diversity (Nei’s gene diversity; h) within population of site A (h A =0.2381) was relatively lower than sites B (h B =0.2761) and C (h C =0.2618 ...
