Fig. 2

Alpha diversity across the data set. Alpha diversity (represented by the Shannon Index) across the data set, representing the diversity of species within each sample group. For each sample, the alpha diversity was calculated based on 10 random subsamples of 5000 OTUs. Significant differences between groups are based on an independent two-sample t-test (** = p ≤ 0.01; * = p ≤ 0.05; ns = not significant). Full alpha diversity values for each individual sample, including observed diversity and Chao1 Index, can be found in Supplementary Table 1
