Variables are the number of alleles (N), observed heterozygosity (H_O), Expected heterozygosity (H_S), Jost's D (D) and global variation in allele frequencies (F _ST). Overall, populations showed a high degree of substructure, as has been observed in other Silene metapopulations. Population structure was high for each marker. Our lowest F _ST corresponded to the only marker composed of a dinucleotide repeat. ¹ [34], ² [35], ³ [36].
