Fig. 5: Microbial co-occurrence networks and robustness analysis of three ecosystems.

From: Supraglacial and subglacial ecosystems contribute differently towards proglacial ecosystem communities in Kuoqionggangri Glacier, Tibetan Plateau

Fig. 5

a Co-occurrence network of supraglacial, subglacial, and proglacial ecosystems from left to right. The sizes of the nodes (ASVs) are proportional to the number of connections. The taxonomy of each node is shown in different colors in the phylum level (phylum Proteobacteria was divided into class levels). Orange edges mean a positive correlation and green edges depict negative correlations. b Robustness measured as the proportion of taxa remained with 50% of the taxa randomly removed from the SparCC network of three ecosystems. Each error bar corresponds to the standard deviation of 100 repetitions of the simulation. The blue dashed line shows the mean robustness of the subglacial network. Error bars represent the standard error of the mean. Comparisons (Kruskal–Wallis test) among three ecosystems are indicated by significance level: *** (P < 0.001). c Robustness measured as the proportion of taxa remained with ASVs presented in supraglacial and subglacial ecosystems removed from the network of proglacial ecosystem. Sample abbreviation as fellows: SUP supraglacial ecosystem, SUB subglacial ecosystem, PRO proglacial ecosystem.
