Rusty-necklaced partridges (Alectoris magna) are found in Qinghai, Ningxia and Gansu provinces of northwestern China, distributed in mountainous areas that were heavily affected by cyclical climate changes throughout the Pleistocene. We investigated the potential impact of Pleistocene range shifts on phylogeographic patterns using 458 nucleotides of mitochondrial control-region from 102 individuals sampled from 10 populations across the current range. We found 31 haplotypes defined by 33 polymorphic positions. Phylogenetic analyses revealed two robustly supported clades, one corresponding to the Chaidamu Basin and the other including all individuals from all other populations. At the population level we also found significant evidence of differentiation. The phylogeographic structure of the rusty-necklaced partridge is consistent with the "phylogenetic discontinuity, spatial separation" pattern outlined by Avise et al. [Avise, J.C., Arnold, J., Ball, R.M., Bermingham, E., Lamb, T., Niegel, J.E., Reeb, C.A., Saunders, N.C., 1987.

环颈鹧鸪（Alectoris magna）分布于中国西北部的青海、宁夏和甘肃三省，分布在整个更新世受周期性气候变化严重影响的山区。我们利用从当前分布范围内10个种群采集的102个个体的线粒体控制区458个核苷酸，研究了更新世范围变化对系统地理学模式的潜在影响。我们发现了由33个多态性位点定义的31个单倍型。系统发育分析揭示了两个得到有力支持的分支，一个对应柴达木盆地，另一个包括所有其他种群的所有个体。在种群水平上，我们也发现了显著的分化证据。环颈鹧鸪的系统地理学结构与阿维斯等人概述的“系统发育间断、空间分离”模式一致[阿维斯，J.C.，阿诺德，J.，鲍尔，R.M.，伯明翰，E.，兰姆，T.，尼格尔，J.E.，里布，C.A.，桑德斯，N.C.，1987年。种内系统地理学：种群遗传学与系统学之间的线粒体DNA桥梁。《生态学年鉴》18，489 - 522]。
