"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. " - Shannon index microbiome
