脆弱的中国眼镜蛇（Naja atra）分布在中国东南部长江以南到越南北方和老挝。大型山脉和水体可能会影响该物种的遗传多样性模式。本研究以台湾地区23个地点的285个个体为研究对象，对线粒体DNA控制区（1029 bp）进行序列测定，并从GenBank中获得18个台湾特有序列，用于系统发育和种群分析。两个不同的分支被确定，一个包括单倍型从两个最西部的地方（河口和米易）和其他包括单倍型从所有采样点，除了米易。结果表明，该群体具有较强的单倍型多样性（h = 1.00）和较低的核苷酸多样性（π = 0.0049）（Φst=0.76，P <0.0001）。 罗霄和南岭是限制基因交流的历史地理屏障。在单倍型网络中有两个“星星”簇。来自罗霄山脉以东人群的单倍型在一个聚类中，来自山脉以西人群的单倍型在另一个聚类中，来自南岭山脉以南人群的单倍型在两个聚类之间。大陆和岛屿人口之间的血统分类是不完整的。至于种群之间或每个种群内部有多少适应性差异，仍然是未知的。我们告诫不要在任何群体内进行远距离调动，特别是在环境差异明显的情况下。
The vulnerable Chinese cobra (Naja atra) ranges from southeastern China south of the Yangtze River to northern Vietnam and Laos. Large mountain ranges and water bodies may influence the pattern of genetic diversity of this species. We sequenced the mitochondrial DNA control region (1029 bp) using 285 individuals collected from 23 localities across the species' range and obtained 18 sequences unique to Taiwan from GenBank for phylogenetic and population analysis. Two distinct clades were identified, one including haplotypes from the two westernmost localities (Hekou and Miyi) and the other including haplotypes from all sampling sites except Miyi. A strong population structure was found (Φst = 0.76, P<0.0001) with high haplotype diversity (h = 1.00) and low nucleotide diversity (π = 0.0049). The Luoxiao and Nanling Mountains act as historical geographical barriers limiting gene exchange. In the haplotype network there were two “star” clusters. Haplotypes from populations east of the Luoxiao Mountains were represented within one cluster and haplotypes from populations west of the mountain range within the other, with haplotypes from populations south of the Nanling Mountains in between. Lineage sorting between mainland and island populations is incomplete. It remains unknown as to how much adaptive differentiation there is between population groups or within each group. We caution against long-distance transfers within any group, especially when environmental differences are apparent.
