最近将叉尾贻贝引入西欧淡水标志着该区域过去几年中最成功的生物入侵之一的开始。然而，西欧第一个入侵种群(S)的时空起源以及随后的传播途径仍在讨论中。因此，在这项研究中，我们的目标是基于年龄修正的时间和空间显式传播模型重建美洲贻贝在西欧的早期入侵历史。数据来自选定地点的时间序列研究以及西欧的广泛空间调查。根据我们的扩散模型，第一次成功进入西欧是在2004年初的主多瑙河，可能是通过内河航行。一旦种群建立，叉尾贻贝随后的传播以跳跃传播和扩散传播相结合为特征。这项研究深入了解了叉尾贻贝非常早期的入侵历史，并强调了主多瑙河对于将非本土淡水物种引入西欧的重要性。
The recent introduction of the quagga mussel into Western European freshwaters marked the beginning of one of the most successful biological invasions during the past years in this region. However, the spatial and temporal origin of the first invasive population(s) in Western Europe as well as subsequent spreading routes still remain under discussion. In this study, we therefore aim at reconstructing the early invasion history of the quagga mussel in Western Europe based on an age-corrected temporally and spatially explicit spread model. Data were derived from time-series studies at selected sites as well as from a broad spatial survey in Western Europe. According to our spread model, the first successful introduction into Western Europe occurred in the Main-Danube Canal in early 2004, probably via inland navigation. Once populations were established, subsequent spread of the quagga mussel was characterized by a combination of jump dispersal and diffusive spread. This study gives insights into the very early invasion history of the quagga mussel and stresses the importance of the Main-Danube Canal for the introduction of non-native freshwater species into Western Europe.
