Diversity (Shannon and Simpson) and species richness (Chao1) indices for CT and GT samples as determined using QIIME.

1: Cluster of similar sequence variants of the 16S rDNA marker gene sequence.
2: Chao1 estimates the species richness of a sample.
3: Shannon index takes into account the number and evenness of species.
4: Simpson index represents the likelihood of two randomly selected individuals in the habitat belonging to the same species.
5: Good’s coverage (C) is calculated as C=1-(s/n), where s is the number of unique OTUs and n is the number of individuals in the sample.
