摘要

了解和管理生物入侵的最大挑战之一是确定引入途径。由于未被注意、未报告,有时甚至是非法的易位,这些信息往往是不完整的。关于克氏原螯虾(Procambarus clarkii)传入欧洲的报告称,它是1973年和1974年首次从路易斯安那州传入西班牙南部;从那里,它迅速蔓延到几个欧洲国家。虽然文献中提出了其他输入事件和引入途径,但没有证据表明这些导致了欧洲的野生种群。我们目前的研究表明,红沼泽小龙虾从非欧洲地区传入欧洲还有另外两条途径,这些地区以前曾报道过红沼泽小龙虾。通过使用mtDNA,我们在肯尼亚的奈瓦沙湖和西欧之间,以及在美国西部或亚洲和马耳他之间发现了一个共享的单倍型。这些发现支持了文献中关于前一种情况的历史报告,也指出宠物贸易是后者新引进的驱动因素,从而突出了欧洲红色沼泽小龙虾种群的复杂引进历史。

Brought more than twice: the complex introduction history of the red swamp crayfish into Europe
One of the biggest challenges in understanding and managing biological invasions is the identification of the routes of introduction. This information is often incomplete because of unnoticed, unreported and, sometimes, illegal translocations. Reports on the introduction of the red swamp crayfish (Procambarus clarkii) into Europe describe that it was introduced for the first time to southern Spain (1973 and 1974) from Louisiana; from there, it rapidly spread throughout several European countries. While other importation events and pathways of introduction have been suggested in the literature, there is no evidence that these led to wild populations in Europe. Our present study suggests two additional introduction routes into Europe from non-European areas where the red swamp crayfish had previously been reported. By using mtDNA, we found a shared haplotype between the Lake Naivasha in Kenya and Western Europe, as well as another between either western United States or Asia, and Malta. These findings support historical reports found in the literature for the former case and also point towards pet trade as driver of new introductions for the latter, thus highlighting the complex introduction history of the red swamp crayfish populations in Europe.

期刊介绍: Knowledge and Management of Aquatic Ecosystems (KMAE-Bulletin Français de la Pêche et de la Pisciculture since 1928) serves as a foundation for scientific advice across the broad spectrum of management and conservation issues related to freshwater ecosystems. The journal publishes articles, short communications, reviews, comments and replies that contribute to a scientific understanding of freshwater ecosystems and the impact of human activities upon these systems. Its scope includes economic, social, and public administration studies, in so far as they are directly concerned with the management of freshwater ecosystems (e.g. European Water Framework Directive, USA Clean Water Act, Canadian Water Quality Guidelines, …) and prove of general interest to freshwater specialists. Papers on insular freshwater ecosystems and on transitional waters are welcome. KMAE is not a preferred journal for taxonomical, physiological, biological, toxicological studies, unless a clear link to ecological aspects can be established. Articles with a very descriptive content can be accepted if they are part of a broader ecological context.
