We analysed 33 brown bears from the Romanian Carpathians and the Italian Apennines at sequences of the mitochondrial control region and nine polymorphic microsatellite loci with regard to genetic variability and haplotype distribution. The Italian brown bears were monomorphic for mtDNA sequences. The Romanian bears yielded the highest variability found so far in this species. Haplotypes of both previously identified mtDNA lineages (western and eastern) were found in Romania. In the eastern part of the Carpathians western and eastern haplotypes occurred sympatrically, the bears from the western part of the mountain range only exhibited western-type sequences. This pattern provides evidence of a mitochondrial phylogeographic break in the distribution of the eastern lineage within the Romanian Carpathians. Conservation implications of this finding are discussed. (c) 2007 Deutsche Geselischaft fur Saugetierkunde. Published by Elsevier GmbH. All rights reserved.
