The OTUs and the bacterial community diversity analysis of all samples from intestines (I), water (W), and sediment (S) in artificial habitats (AI, AW, and AS) and control areas (CI, CW, and CS) are shown. The means ± SD data of Table 1 in the same row with different letters differ significantly (P < 0.05)
