Figure 2.

Alt text The figure represents 6 subplots (A–F) of microbial diversity and structure. Subplots (A) and (B) are boxplots of alpha diversity (Chao1, Shannon indices) across the 4 groups (HM: Meriones meridianus from high-rain regions; LM: Meriones meridianus from low-rain regions; LD: Dipus sagitta from low-rain regions; HD: Dipus sagitta from high-rain regions). Different letters above the whiskers represent statistically significant differences (P < 0.05). Subplot (C) shows a PCoA plot with Bray–Curtis distances. Subplot (D) is a bar chart of 8 core genera (y-axis: relative abundance; x-axis: samples), with colors denoting genera. Subplot (E) is a cladogram illustrating phylogenetic relationships between microbial taxa across groups. Subplot (f) is an LDA histogram showing microbial taxa with significant differences (P < 0.05, Kruskal–Wallis test, LDA score > 4.0).

Diversity, structure, and composition in D. sagitta and M. meridianus. Box and whisker plots of 2 alpha diversity indices (A) Chao1 and (B) Shannon indices in each group. Different letters above the whiskers denote significant differences between each group determined with analysis of variance tests (P < 0.05). (C) PCoA plots showing group variation in the bacterial microbiome based on Bray–Curtis dissimilarity. The ellipses indicate the 95% confidence intervals, and the percentages in parentheses are the proportions of variation explained by the PCoA. (D) The 8 core genera (present in more than 50% of samples in each group with a relative abundance of more than 0.5%.) across all samples. (E) Cladogram depicting the phylogenic relationships between microbial taxa, which were significantly different in each group. Yellow nodes represent no significant differences. (F) The LDA histogram represents the bacterial groups with significant differences between groups (P < 0.05, Kruskal–Wallis test; logarithmic LDA score > 4.0).
