  1. The OTUs (97% similarity), Chao1, Phylogenetic Distance, Shannon, and Simpson diversity indices were estimated in QIIME. Rarified OTU, Chao1, and Phylogenetic Distance estimates were rarefied (rfd) to a depth of 1,100 reads to reduce sampling heterogeneity. * Significant difference, (OTUs, P = 0.019; Chao1, P = 0.020).
