Abstract

Abstract. The freshwater flatworm Crenobia alpina (Platyhelminthes, Tricladida, Planariidae) lives almost exclusively in cold springs and crenal streams and possesses only limited dispersal ability. In this study fragments of the COI and 18S rRNA genes were used to estimate genetic divergences among 37 C. alpina populations from the European Alps. Phylogenetic analyses revealed five geographically and genetically distinct groups and at least 10 distinct lineages of C. alpina across the European Alps. Our study suggests that C. alpina represents a complex of numerous cryptic species. Speciation (allopatric and/or sympatric) may have been facilitated by the orogenetic activity of the Alps and the high habitat specificity.

高山扁虫Crenobia alpina的遗传多样性

摘要淡水扁虫Crenobia alpina (platyhelmintes, Tricladida, Planariidae)几乎只生活在冷泉和溪涧中，只有有限的传播能力。本研究利用COI和18S rRNA基因片段，对欧洲阿尔卑斯地区37个高山雪杉居群的遗传差异进行了分析。系统发育分析表明，在欧洲阿尔卑斯山脉分布有5个地理和遗传上不同的类群和至少10个不同的谱系。我们的研究表明，C. alpina代表了许多隐种的复合体。阿尔卑斯山脉的造山活动和高生境特异性可能促进了物种形成(异域和/或同域)。

期刊介绍： Web Ecology (WE) is an open-access journal issued by the European Ecological Federation (EEF) representing the ecological societies within Europe and associated members. Its special value is to serve as a publication forum for national ecological societies that do not maintain their own society journal. Web Ecology publishes papers from all fields of ecology without any geographic restriction. It is a forum to communicate results of experimental, theoretical, and descriptive studies of general interest to an international audience. Original contributions, short communications, and reviews on ecological research on all kinds of organisms and ecosystems are welcome as well as papers that express emerging ideas and concepts with a sound scientific background.
