Abstract

Abstract: Studies have indicated that the abundance and community structure of gut microbiota are altered by diet. In this study, next‐generation sequencing of the 16S rRNA gene amplicon was performed to evaluate variations in the gut microbiota of wild and captive individuals of both sexes of Calotes versicolor . The results showed that there was a significant sex difference in microbial community structure for wild C. versicolor, Bacteroide was the dominant genus in wild females (WF), whereas Ochrobactrum was the dominant genus in wild males (WM). Acinetobacter and Hymenobacter were the dominant genera in WF, while Clostridium was the dominant genus in captive females (CF). The results indicated that differences in diet between wild and captive C. versicolor also resulted in variations in gut microbiota. Thus, it was not surprising that captivity and sex shape the gut microbiota in C. versicolor . In summary, the fundamental information presented about the gut microbiota of both sexes of wild (and captive females) C. versicolor, indicates that the artificial environments are not suitable for the wild C. versicolor . Abstract : Relationships between bacterial and KEGG pathway by sex (a) and captive (b). Pairwise comparisons of bacterial were displayed with a color gradient denoting Spearman's correlation coefficient. Bacterial and KEGG community composition was related to each bacterium by Mantel test.
