Sampling sites and statistics of genetic variation for 11 Fraxinus angustifolia populations in Croatia at six microsatellite loci.

n - sample size; Na - average number of alleles per locus; Nar - allelic richness; Npr - total number of private alleles; HO - observed heterozygosity; HE - expected heterozygosity; HEnull - expected heterozygosity calculated on allele frequencies corrected for null-alleles;†P-value of the permutation tests for differences between the putative ecotypes for Nar, HO, and HE.
