利用线粒体基因COI和16 S的DNA序列数据构建了钩虾属Gammarus Fabricius，1775的一个系统发育。以及核基因18 S和28 S。简约和贝叶斯分析进行单独和合并的数据分区。选择来自组合分析的贝叶斯系统发育作为优选的系统发育假设。该假说支持钩虾属的单系性、欧洲-北美钩虾属的并系性和亚洲钩虾属的单系性。亚洲分支进一步分裂为东南群和西北群。青藏高原隆升后的剧烈气候变化可能是引发东南和西北群体多样化的最重要因素。Sinogammarus属无效，应属于Gammarus属的一部分。(C)2007年爱思唯尔公司All rights reserved.
A phylogeny of the genus Gammarus Fabricius, 1775 was constructed using DNA sequence data from the mitochondrial genes COI and 16S. and the nuclear genes 18S and 28S. Both parsimony and Bayesian analyses were conducted on separate and combined data partitions. The Bayesian phylogeny from the combined analysis was selected as the preferred phylogenetic hypothesis. The hypothesis supports monophyly of the genus Gammarus, paraphyly of the European-North American Gammarus, and monophyly of the Asian Gammarus. The Asian clade was further split into a southeastern group and a northwestern group. The dramatic climate change following the uplift of the Tibetan Plateau was probably the most important factor in triggering the diversification of southeastern and northwestern groups. The genus Sinogammarus is invalid and should be part of the genus Gammarus. (C) 2007 Elsevier Inc. All rights reserved.
