Musk deer Moschus spp. are endemic to the high mountain forests of central Asia. The taxonomic status of musk deer in the central and western Himalayas is poorly understood. We investigated the phylogenetic relationship of musk deer from the central and western Himalayas based on mitochondrial genomic data of Cytochrome b (380 bps) and D-loop (1000 bps). Our results distinguished two divergent lineages using higher bootstrap support (bs) values from the Maximum likelihood and Bayesian posterior probabilities (bpp). Both the Manang and Kaski lineages from central Nepal are confirmed as Himalayan musk deer Moschus leucogaster and represent a species complex widespread throughout the central and eastern Himalayan region. The musk deer Mustang lineage was confirmed as Kashmir musk deer Moschus cupreus and has wide distribution in the western Himalayas (from central Nepal to Afghanistan). Our analysis validates that Kashmir musk deer is a genetically distinct species and it clarifies that Himalayan musk deer and Kashmir musk deer are confirmed instead of Alpine musk deer Moschus chrysogaster which has been previously described from the southern parts of Himalayas of Nepal, India and Pakistan.
麝鹿属(Moschus spp.)是中亚高山森林的特有物种。喜马拉雅山脉中部和西部地区的麝鹿分类地位了解甚少。我们基于细胞色素 b(380 bps)和 D 环(1000 bps)的线粒体基因组数据,研究了喜马拉雅山脉中部和西部地区麝鹿的系统发育关系。我们的研究结果使用来自最大似然法和贝叶斯后验概率(bpp)的更高自举支持(bs)值,区分了两个不同的谱系。来自尼泊尔中部的马南和卡斯基两个谱系均被确认为喜马拉雅麝鹿(Moschus leucogaster),代表了广泛分布于喜马拉雅山脉中部和东部地区的物种复合体。麝鹿(Mustang)谱系被确认为克什米尔麝鹿(Moschus cupreus),并广泛分布于喜马拉雅山脉西部(从中部尼泊尔到阿富汗)。我们的分析证实,克什米尔麝鹿是一个具有独特遗传特征的物种,它澄清了喜马拉雅麝鹿和克什米尔麝鹿是被确认的物种,而不是之前描述的来自尼泊尔、印度和巴基斯坦喜马拉雅山脉南部的阿尔卑斯麝鹿(Moschus chrysogaster)。
