N is the number of individuals sampled per population, NA is the mean number of alleles per locus, A is the mean allelic richness per locus (based on n = 10) and NPA is the number of private alleles. Estimates of observed heterozygosity (HO), gene diversity (H) and inbreeding coefficient (FIS) are also given.
* 0·01 < P < 0·05, *** P < 0·001
† For the private alleles, the first number is the number of alleles private to a given range (invasive or native) in the considered population, while the number in parenthesis is the number of alleles that are private to the considered population in its range.
