Fig. 6. Boxplots depicting plant species richness of Cassiope tetragona (n = 29), Dryas octopetala (n = 20), and Silene acaulis (n = 35) groups. Statistical analysis is carried out according to a parametric unbalanced ANOVA (Welch’s ANOVA), followed by a test of Games–Howell honest significant difference for post hoc comparisons. Plant richness does not significantly differ between the dominant plant communities. The central horizontal lines within the boxes indicate the medians; the box edges indicate the quartiles; and the whiskers indicate the minimum and maximum values. C.te: Cassiope tetragona; D.oc: Dryas octopetala; S.ac: Silene acaulis.
