Location of studied populations of Saxifraga wahlenbergii and their genetic variability based on DNA sequence data A distribution of 11 populations of S. wahlenbergii and haplotypes and ribotypes in the populations B haplotype network based on the combined chloroplast regions: rps16-trnK and rpl32-trnL C ribotype network based on ITS region. Networks obtained from TCS based on a 95% connection limit. The relative sizes of circles in networks are proportional to haplotype and ribotype frequencies. For population acronyms see Table 1.
