Megjegyzések:The distribution of the Imperial Eagle (Aquila heliaca) in the Carpathian Basin is not continuous, since western andeastern breeding pairs are separated by 150 km from each other in Slovakia, and 70 km in Hungary. In the present study our aimwas to examine whether this geographical distance has resulted in any genetic separation between the Western and Eastern Slovakbreeding groups. We have used 132 shed feathers and 128 blood samples collected in the fields geographically representingthe whole of the Slovak breeding population, and included all juveniles ringed between 2004 and 2006. After successful DNAextractions we have determined the sex, microsatellite DNA-profiles and mtDNA control region haplotypes of the specimens.Data were integrated in a common Hungarian-Slovak "DNA-fingerprint" database, making identification of the same specimenpossible when recaptured. Based on a subsample of the collected individuals, the genetic structure of the Slovak population wastested using ten microsatellite loci and mtDNA control region haplotypes, and marginally significant genetic differentiation wasfound between western and eastern subpopulations. These results suggest that, in spite of the large dispersal capacity of the species,a relatively small geographic distance can also decrease the exchange rate of individuals between subpopulations. As thisresult involves only samples from the northern part of the breeding area, major conclusions concerning genetic structure and gene flow of Imperial Eagles in the entire Carpathian Basin population cannot be drawn without sampling and analysing the southernsubpopulations in Hungary.
