Comparison of the estimated operational taxonomic unit (OTU) richness and the diversity indices of the 16S rRNA gene libraries obtained from the pyrosequencing analysis

Site/diversity index	OTUs richness	Shannon_H index	Evenness	Chao 1 index
CSR	1160.22 (370.731) a	4.83 (0.311) a	0.12 (0.042) a	1715.11 (364.704) a
ISR	759.89 (248.028) a	5.30 (0.237) a	0.27 (0.025) a	1143.18 (275.249) a
