Recent studies have argued that this metric is a more accurate method of measuring differentiation between communities (Chao et al., 2024; Ohlmann et al., 2024). As seen with the other metrics, the Hill-Shannon index recovered a low level of diversity per time point. WebbNational Center for Biotechnology Information

WebbShannon evenness index (Shannon's equitability index) is a pure diversity index, independent of species richness. It measures how evenly the microbes are distributed in a sample without considering the number of species. Values can range from zero to one: from high dominance of a single species to perfectly equal abundances across all species.
