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.

Webb15 okt. 2024 · The microbiome provides an array of digestive functions, forming a resilient community that can easily adapt to changes in your life, like changes in diet, stress levels, and medications (if only we were all so tough!). And as we’re discovering through our PREDICT studies, your microbiome has a big impact on how your body responds to food. 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.
