Figure 8.
Principal coordinates analysis (PCoA) of 71 multilocus haploid genotypes of Sphagnum warnstorfii for the CZ-SK-BG dataset with significant linear regression of pH (R2 = 0.1002, P < 0.05). The first three principal coordinates account for 14.22%, 11.77%, and 9.07% of the total genetic variation. The arrow indicates the direction of the significant linear regression, and size of the circles is proportional to the pH value.
