Webb12 dec. 2024 · The dynamics of α -diversity in the process of restoration were analyzed by calculating Shannon index ( Shannon and Weaver 1949 ), Simpson diversity index ( Simpson 1949 ), Pielou evenness index ( Pielou 2011) and Richness index. We also calculated jaccard similarity index as β -diversity index. The formulas are as follows: WebbCompared with the baseline, there were no significant differences in the total copies of Proteobacteria (Figure S6A–C), Shannon–Wiener Diversity Index (Figure S6D–F), …

WebbAccording to Table 2, the Pollution Tolerance Index (PTI) of Site 1 is 26 which is excellent according to the stream quality assessment. The Hilsenhoff Family Level Biotic Index (HFLBI), excluding the family of Hydrachida, is 6.13 meaning it has fairly poor water quality and substantial pollution is likely. The Shannon Weiner Index of Diversity (H’) of Site 1 is … WebbFör 1 dag sedan · The diversity of mollusc species found in the present study was analyzed using the Shannon-Wiener index (H’), Pielou’s equitability (J), and Simpson’s index of dominance (D) and diversity (1-D), which are the most used in studies of this type (Mendes et al. 2008 MENDES RS, EVANGELISTA LR, THOMAZ SM, AGOSTINHO AA & GOMES LC. … impact collections
