aPopulation size classes: S, <200 flowering ramets; M, 200–1000 flowering ramets; L >1000 flowering ramets.
bDegree of geographical isolation of the population as estimated with Dist1, distance to nearest population (km) and Dist2, mean distance to the rest of the populations (km).
cP99, percentage of polymorphic loci (0·99 criterion); A, mean number of alleles per locus; Ho, mean observed heterozygosity; He, gene diversity or expected heterozygosity (unbiased estimate; Nei, 1978); and FIS = Wright's inbreeding coefficient. Statistically significant multilocus inbreeding coefficients (P < 0·05) are in bold type.
dComputed by combining the data for all individuals (n = 858) into a single sample.
