Title Πληθυσμιακή δομή των λαγών της Κρήτης σε σχέση με πληθυσμούς της υπόλοιπης Ελλάδας

Abstract The phylogeographic structure of the European hare (Lepus europaeus Pallas, 1778) remains largely unknown, despite the high number of miscellaneous studies conducted across Europe. We have used three microsatellite primer pairs to determine the micro and macro-geographical genetic structure of European hares in terms of nuclear DNA. Variability in microsatellite DNA loci of 142 european hares from Crete and 171 from insular and continental parts of Greece as well as Cyprus and Italy was studied. A rich gene pool variability in all studied hare populations is suggested by high values of average expected heterozygosity (Ηe= 0.6881) and mean number of alleles (A= 6.66). The observed high level of genetic differentiation between hare populations (FST= 0.19) suggests slight gene flow between populations probably due to “ultimate” barriers (islands) and to a major effect of geographical distance. Substantial FST values observed at close populations in terms of geography can be explained by demographic parameters. Population phylogenetic analyses results to the formation of two distinct groups (insular and continental populations) in a way that can not be easily interpreted only with the appeal of historical parameters. The population structure observed in Greek populations is over against the almost complete absence of genetic structure observed in larger geographical scale (central and northern Europe). This is in accordance with the hypothesis suggested by mtDNA data that European hare probably differentiated in isolated refuges of Balkan peninsula during the last glaciation. Combination of our data and mtDNA data are indicative that limited gene flow is due to both sexes contrary to some ecological dispersion studies.
