  <dc:description xmlns:ns0="xml" ns0:lang="en">Pilosella alpicola subsp. ullepitschii (Asteraceae) is a strictly allogamous, diploid  Carpathian endemic. Its distribution range comprises two areas separated by about  600 km. While in the Western Carpathians (Slovakia and Poland) the taxon occurs in  numerous sites, only four localities of man-made origin are known from the Eastern  and Southern Carpathians (Romania). We used allozyme markers to test two likely  possible scenarios for the origin of this disjunction: long distance dispersal and  vicariance. Our data indicate a significant loss of genetic diversity in the isolated  Eastern and Southern Carpathian populations in following genetic parameters  (averaged per region): percentage of polymorphic loci (38.9% found in the Eastern  and Southern Carpathians versus 58.3% in the Western Carpathians), allelic richness  (1.4 vs. 1.6), expected heterozygosity (0.134 vs. 0.235), mean number of  distinguishable multilocus genotypes (4.3 vs. 10.6) and proportion of distinguishable  multilocus genotypes (0.34 vs. 0.68). Higher proportion of homozygous loci found in  the Eastern and Southern Carpathian populations might indicate a higher rate of  inbreeding due to non-random mating. We assume that these genetically depauperate  populations have experienced a very strong genetic bottleneck, probably due to a  founder effect. Although our data suggest that the long-distance dispersal model is  most likely, more discriminate genetic markers should be used to test this further.</dc:description>
