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.

ENS is an extension to the Shannon-Weaver index (Eq. 1), accounting for evenness or entropy. The ENS transforms the Shannon-Weaver index in the more intuitive measure of units of effective species (Jost, 2006).
