Fig. 3: Microbial network complexity in soils derived from Ca-rich and Ca-poor parent materials.
From: Calcium-rich parent materials enhance multiple soil functions and bacterial network complexity
a, c Co-occurrence networks of soil bacterial and fungal communities. The sizes of the nodes (OTUs) are proportional to the number of connections. Only nodes that were significantly correlated with each other (p < 0.05) were connected (edges). b, d Bacterial and fungal network topological characteristics, including average degree, edge number, and node number. Bars in (b) and (d) represent means ± standard errors. **p < 0.01; ***p < 0.001. ns not significant (p > 0.05).
