Fig. 6From: Variations in diversity, composition, and species interactions of soil microbial community in response to increased N deposition and precipitation intensity in a temperate grasslandEcological networks of soil bacteria (a) and fungi (b) at OTU level, node numbers (c, g), edge numbers (d, h), degree (e, i) and cluster coefficient (f, j) were used to estimate the complexity (c–j). The nodes are colored according to bacterial and fungal models, and node size indicates the degree of connection. The asterisk above the horizontal line represents a significant difference between the two groups, with *P < 0.05, **P < 0.01, and ***P < 0.001Back to article page
