Species evenness is calculated by dividing the entropy (Shannon index) by the logarithm of the number of ASVs. A value of 1 on the evenness index indicates a perfectly even (equal abundance) sample, whereas small values indicated a skewed distribution. Groups are compared using Kruskal-Wallis analysis. *p<0.05; **p<0.01; ***p<0.001Back to article page
