Phylogeography of chukar partridge (Alectoris chukar) in China based on mtDNA control region

AbstractThe chukar partridge (Alectoris chukar) is distributed in north and northwest of China, in mountainous areas that were heavily affected by cyclic climate and landscape changes during the last Pleistocene glaciations. Some partridge populations have colonized and expanded their present ranges only after deglaciation and recent deforestation by human. Consequently, partridges from different areas could be genetically differentiated. In this study, a 1152–1154 bp portion of the mitochondrial DNA control region were analyzed for all 279 specimens collected from 28 populations through their distribution in China. A total number of 91 haplotypes were defined by 113 variable sites. The mean haplotype diversity and nucleotide diversity were 0.939 ± 0.008 and 0.0030 ± 0.0017, respectively, for chukar. Haplotype diversity among the 28 populations varied from 0.600 ± 0.215 (HH) to 1.000 ± 0.272 (SBC), and nucleotide diversity ranged from 0.0006 ± 0.0007 (HJ) to (0.0071 ± 0.0041) (HEG). The nucleotide diversi...
