Figure 5.

The ordination based on placement-factorization showing the distribution of root (R) and soil (S) AMF communities associated with P. trivialis (Pt) and Ph. australis (Pa) at the contaminated (K) and the uncontaminated site (C). Placement-factorization indicates the relationship between changes in the abundance of clades in the phylogenetic tree and changes is soil-physicochemical features assessed by the generalized linear model (GLM). Axes represent the balances of the winning edges of the first three phylofactors (F1, F2 and F3, Figure S5). Placement-factorization was performed considering only phenol and PAH contamination (A) and with all meta-data (phenol and PAH contamination, Ntot, SOM, pH_KCl pH H₂O, moisture) (B).
