In this study, we add further information about their genetic variation, differentiation, and admixture using maternal and codominant (microsatellites) molecular markers. The phylogeographic analysis demonstrated the distinct distribution of mitochondrial haplotypes across the sampled geographic range. Cluster analysis detected two main groups of colonies while further discriminant analysis of the principal components supported the existence of ecotypes within A. m carnica and A. m. macedonica, and admixture of them. The extent of introgression and the presence of foreign haplotypes in some of these populations suggested that introductions of non-native subspecies represent a serious threat to the genetic integrity of native honey bee populations due to the creation of hybrid populations. eng restricted access Wide genetic diversity in Old World honey bees threaten by introgression journal article
