Title

GEOGRAPHIC STRUCTURE AND DEMOGRAPHIC HISTORY OF IRANIAN BROWN BEAR (URSUS ARCTOS) BASED ON MTDNA CONTROL REGION SEQUENCES

Pages

  25-38

Abstract

 In recent years, the BROWN BEAR's range has declined and its populations in some areas have faced extinction. Therefore, to have a comprehensive picture of genetic diversity and geographic structure of populations is essential for effective conservation strategies. In this research, we sequenced a 271bp segment of mtDNA control region of seven Iranian BROWN BEARs, where a total dataset of 467 sequences (brown and polar bears) were used in analyses. Overall, 113 different haplotypes and 77 polymorphic sites were identified within the segment. Based on phylogenetic analyses, Iranian BROWN BEARs were not nested in any other clades. The low values of Nm (range=0.014-0.187) and high values of Fst (range=0.728-0.972) among Iranian bears and others revealed a genetically significant differentiation. We aren't found any significant signal of demographic reduction in Iranian bears. The time to the most recent common ancestor of Iranian BROWN BEARs (Northern Iran) was found to be around 19000 BP.
