Figure S2: Observed, Faith’s phylogenetic, Shannon and Simpson alpha diversity indexes from M. festivus gut samples (n = 40) amplified using different blocking primer combinations (n = 5). We clustered and colored samples according to their blocking primer group. The plot was produced using the function plot_richness fromPhyloseq . There was a significant difference between the phylogenetic diversity from the M_2X group and the control (p-value < 0.05), but there was no significant difference in in Shannon and Simpson diversity indexes (p-value > 0.9).
