Fig. 5From: Forest age and topographic position jointly shape the species richness and composition of vascular plants in karstic habitatsNumber of vascular plant species (all plant species and oak forest species) in the plots of topographic positions in dolines (S: south-facing slope, B: bottom, and N: north-facing slope) (mean ± SE). Significant differences (p < 0.05, based on the GLMMs with Bonferroni post hoc tests) are indicated by different lower case (a–c) lettersBack to article page
