Fig. 1 Habitat of Viridovipera stejnegeri (a) in Guizhou (b) and Anhui (c) populations.
Fig. 2 Relative abundance of gut bacteria in three populations of V. stejnegeri at the phylum level. Abscissa represents three sampling areas, different colors represent classification of bacteria at the phylum level. Full names of the three sampling areas are provided in Fig. 1.
Fig. 3 Relative abundance of gut bacteria in three populations of V. stejnegeri at the genus level. Different colors represent classification of bacteria at the genus level. Full names of the three sampling areas are provided in Fig. 1.
Fig. 4 PCoA of Bray-Curtis distance matrix for bacterial diversity differences among three populations of V. stejnegeri.
Fig. 5 LEfSe of the three populations of V. stejnegeri . LDA scores identify significantly different taxa among Anhui, Guizhou, and Hunan populations. Degree of influence of a taxon is expressed by bar length. Only taxa meeting a significant LDA threshold > 2 are shown. Letters p, c, o, f, and g represent phylum, class, order, family, and genus, respectively.
Fig. 6 Relative abundance of CAZymes in V. stejnegeri across three populations.
Fig. 7 Differences in CAZymes among three populations ofV. stejnegeri . LDA scores reflect differences in relative abundance of CAZymes among populations.
