Table 1.
The values of α-diversity estimators (mean ± SD) of the roots and soil AMF communities associated with P. trivialis (Pt) and Ph. australis (Pa) collected from the site contaminated with phenol and PAHs and the uncontaminated site. p-values from the permutational analysis of variance (PERMANOVA) indicate significant differences between the AMF communities associated with different sites, plants, or matrices (roots/soil). p-values from the Kruskal–Wallis test indicate significant differences between the AMF communities for each estimator (species observed, Chao1, ACE, Shannon Index, Evenness Index). Significant post-hoc pairwise Mann–Whitney U comparisons (p < 0.05) between the communities for each estimator are indicated by different superscript letters.
