Table 4. Major topological properties of the single factor co-correlation networks of fungal and bacterial communities.

The number of original OUTs was used for network construction by random matrix theory (RMT)-based approach. Network size was the number of nodes in the network. Network diameter was the maximum distance between any two nodes in the network. Transitivity was the probability that two connected nodes of the same node were still connected to each other.

	Number of original OUTs	Network size	Number of genus	Network diameter	Transitivity	Average connect	Average clustering coefficient	Average path distance
Fungi	400	220	25	4	0.70	4.4	0.67	1.86
Bacteria	400	320	25	4	0.82	6.4	0.79	1.57
