We investigated phylogenetic relationships among north Mediterranean species of the genus Barbus using sequences of the cytochrome b gene. Our results indicate that the species belong to two major clades that are consistent with those previously defined from morphological features. The first clade includes species ranging from France to the Black Sea. In this clade, there is a well-supported monophyletic group of large-sized fluvio-lacustrine barbs; however, the monophyly of the small-sized rheophilic species is not clear. The second clade comprises species found in Spain, Greece, and Asia Minor and probably represents the oldest group present in the north Mediterranean rivers. In general, there is good concordance between geography and phylogenetic relationships. These results are compared to those from previous morphological- and allozyme-based studies and demonstrate widespread discordance and polyphyly in the traditional taxonomy of the genus Barbus. This study is one of the first reporting the phylogenetic and biogeographic relationships of a genus that is widely distributed in European rivers and contains species that are a major component of the European ichthyofauna.
我们利用细胞色素b基因序列研究了北地中海地区魮属物种之间的系统发育关系。我们的结果表明，这些物种属于两个主要分支，这与之前根据形态特征定义的分支一致。第一个分支包括从法国到黑海的物种。在这个分支中，有一个得到充分支持的大型河川湖泊魮单系群；然而，小型喜流物种的单系性并不明确。第二个分支包括在西班牙、希腊和小亚细亚发现的物种，可能代表了北地中海河流中现存最古老的群体。总体而言，地理分布与系统发育关系之间存在良好的一致性。这些结果与之前基于形态学和等位酶的研究结果进行了比较，结果表明，在魮属的传统分类中，广泛存在不一致性和多系性。这项研究是最早报道一个广泛分布于欧洲河流且其物种是欧洲鱼类区系主要组成部分的属的系统发育和生物地理关系的研究之一。
