Fig. 5

Amplicon sequence variants (ASVs) richness (a–g) and relative abundance (h) of fungal communities associated with Pinus contorta subsp. murrayana needles in introduced plantations and invasion fronts growing from plantations in Patagonia, respectively. Richness is presented as the average rarified richness for each sample. Results from the corresponding Welch’s t or Wilcoxon rank sum tests are reported in Table S5. Different letters above boxplots (a–g) or across bar segments with the same shade (h) indicate significant differences at α = 0.05.
