中文摘要	通过分析中国北部荒漠地区9个石鸡种群114个样本的mtDNA Cytb 830 bp序列长度,来探讨其遗传保护.114个样本共发现19个变异位点和14种单倍型.AMOVA分析结果表明: 遗传差异主要来自种群内部,占87.45%.位于可能的冰期避难所的北山、贺兰山、寿鹿山种群的遗传多样性均较高,由于高度的隔离进化,各自遗传分化显著,所以将这3个种群划为3个进化显著单元.由于亚种间的基因渗透,祁丰种群遗传多样性较高,其余5个种群遗传多样性相对较低,基因流较大,遗传分化不显著.基于武都种群正在经受奠基者效应和瓶颈效应以及低纬度边缘种群的进化意义,建议应该重点保护武都种群.
英文摘要	The direct sequencing method was used to analyze the genetic conservation of chukar partridge (Alectoris chukar) distributed in the desert area of Northern China. A total of 830 bp nucleotides of the mitochondrial DNA Cytb genes were sequenced in 114 chukar partridges of nine populations collected from the desert area of Northern China. The 19 variable sites defined 14 haplotypes. Genetic diversity is high in BS, HL, SL population, and the pairwise divergence between these three populations and most of other populations are significant due to their high isolation. So we defined them as three ESUs. Conversely, other populations showed a relatively low genetic diversity and no significant differentiation, except QF, whose genetic diversity is high because it is a contact zone of two subspecies. More attention should be paid to WD for its protection because it has encountered a founder effect and bottleneck and suffered from the special ecological environment.
