Fig 1 Explanatory
factors associated with features of the fungal-plant network in
individual (a& b ) and aggregate (c ) (Only the top
three factors are shown to be formally significant). (a ) Random
forest analysis showing influences on number of fungal OTUs linked to
each plant species, number of edges and modularity of plant-fungi
network. (b ) The heatmap of spearman correlation coefficients
between the network features and environmental factors. (c ) The
explained variation values were estimated with the multiple regression
on distance matrices analysis. The results showed that plant species
richness is the most important predictor for plant-fungi network
topological features. MAP, mean annual precipitation;
MAT, mean annual temperature;
CNratio, carbon: nitrogen; SM, soil moisture; STP, soil total
phosphorus; SOC, soil organic carbon. *P < 0.05,
**P < 0.01, ***P < 0.001.
