Table 1 Potential factors contributing to variation in plant–fungus network structure. For each response variable representing network structure, an ANOVA model including the number of plant species/taxa, that of fungal OTUs, network connectance, sampling locality, and the category of plant–fungus networks was constructed

From: Structural diversity across arbuscular mycorrhizal, ectomycorrhizal, and endophytic plant–fungus networks
