Results of the hierarchical Bayesian multiple regression on genetic variation within populations (GV_within) calculated on species-independent level. Modal values of marginal distributions of each standardised regression coefficient are given together with the effective sample size (ESS) of all parameters. A 95% highest density interval (HDI) was computed for each model parameter. The distance to the next calcareous grassland in 1830 (D₁₈₃₀) exhibits a credible impact on the genetic variation of all species at the selected study sites (in italic letters) as HDI <0 (RC standardised regression coefficient)
