摘要马萨加（masasauga Sistrurus catenatus）在历史上被划分为三个亚种，但这种长期存在的分类方法最近受到了质疑。遗传研究现在确认该物种分裂为东部马萨加S. catenatus和西部马萨加S. tergeminus，后者分裂为两个亚种，沙漠马萨加S. t. edwardsii和草原马萨加S. t. tergeminus。尽管在地理上孤立的S. catenatus和S. tergeminus种群之间的区别在遗传学上得到了很好的支持，但由于在整个物种范围内取样不完整，S. tergeminus和S. edwardsii种群之间的地理关系仍未得到解决。这对该物种的保护和管理提出了严峻的挑战。虽然没有州或联邦的保护地位，但根据美国濒危物种法案，S. t. edwardsii已被申请列入名单。在这项研究中，我们使用了细胞核和线粒体…
Abstract The massasauga Sistrurus catenatus was historically divided into three subspecies, but this long-standing taxonomy has recently been called into question. Genetic research now recognizes a split of the species into the eastern massasauga S. catenatus and western massasauga S. tergeminus, with the latter split into two subspecies, the desert massasauga S. t. edwardsii and the prairie massasauga S. t. tergeminus. Although the distinction between geographically isolated populations of S. catenatus and S. tergeminus is well-supported genetically, the geographic relationships among populations of S. t. tergeminus and S. t. edwardsii remain unresolved because of incomplete sampling throughout the species’ range. This poses a difficult challenge for conservation and management of this species. Sistrurus t. tergeminus does not have state or federal conservation status, but S. t. edwardsii has been petitioned for listing under the U.S. Endangered Species Act. In this study, we used nuclear and mitochondri...
