Figure 3. Non-metric multidimensional scaling (NMDS) ordination of the study plots across three forest age classes (Y: Young, M: Medium, O: Old) based on fungal communities of (a) kingdom fungi and (b) ectomycorrhizal fungi.

In each diagram, soil and plant characteristics that showed a significant goodness of fit based on post-hoc correlations (P≤0.05) are represented as vectors. Stress values represent percentages.
