Fig 5 Random Forest analysis and linear regression showing
influences on the network-level topological features of fungi-only
network(left) and bacterial-only network(right). Random forest shows
that STP is the most important environmental factors for the fungi-only
network (a ), while SM is the most important for the
bacteria-only network (b ). 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 and ***P< 0.001.
