The invasion of the zebra mussel, in the Great Lakes of North America is regarded as one of the most catastrophic ecological events in recent history. Previous studies showed a close kinship between European zebra mussels and their invasive cohorts in the Great Lakes. In this study, we repurposed and reanalyzed archived CO1 sequence data from Lake Superior and multiple sites in Europe that were collected between 1991 and 2011 to illustrate an interesting pattern of genetic isolation that was overlooked in previous studies. The results showed extreme genetic isolation of Lake Superior zebra mussels as evident by high ϕ values and strong geographic patterning of Lake Superior haplotypes.
斑马贻贝入侵北美五大湖被视为近代以来最具灾难性的生态事件之一。此前的研究表明，欧洲斑马贻贝与其在五大湖的入侵群体之间存在密切的亲缘关系。在本研究中，我们重新利用并重新分析了1991年至2011年间从苏必利尔湖和欧洲多个地点收集的存档CO1序列数据，以阐明一种在以往研究中被忽视的有趣的遗传隔离模式。结果显示，苏必利尔湖斑马贻贝存在极端的遗传隔离，高ϕ值和苏必利尔湖单倍型的强烈地理模式证明了这一点。
