Fig. 2: Fungal community diversity and composition among eight stonefly families.

a Richness and Shannon indices of different stonefly fungal communities. Different letters denote significant differences between stonefly families with ANOVA tests (p < 0.05). b Principal coordinate analysis (PCoA) of fungal community Bray-Curtis dissimilarities with permutational analysis of variance among different stonefly families. The variation explained by each principal coordinate is denoted in parentheses. c Relative abundances of each fungal genus in different stonefly families. d Co-occurrence networks of the fungal communities from each stonefly family based on Spearman’s correlation analysis between OTUs. Blue and red lines represent significant negative and positive correlations, respectively. The sizes of the points indicate the relative abundance of OTUs in each microbial community.
