雀形目(Passeriformes)莺科(Sylviidae)鸟类广泛分布于旧大陆,该科许多种类的系统发育关系一直存在争议.本研究采用分子系统学方法,对莺科11属37种鸟类的cyt b全基因序列和COI部分基因序列进行系统发育分析,构建TML和Bayesian系统发育树.结果显示,柳莺属(Phylloscopus)并非单系发生,(鹟)莺属(Seicercus)可能是其同类或其属下的一个类群;在柳莺属内,乌嘴柳莺(P.magnirostris)与极北柳莺(P. borealis)亲缘关系较近;黄腰柳莺(P.proregulus)、云南柳莺(P.yunnanensis)、橙斑翅柳莺(P. pulcher)及灰喉柳莺(P. maculipennis)亲缘关系较近;黄腹柳莺(P.occisinensis)、巨嘴柳莺(P.schwarzi)、棕眉柳莺(P. armandii)、叽喳柳莺(P. collybita)及褐柳莺(P.fuscatus)亲缘关系较近;树莺属(Cettia)并非单系发生,与拟鹅莺属(Abroscopus)和地莺属(Tesia)聚在一起;大苇莺属(Acrocephalus)为单性系;此外,林莺属(Sylvia)与绣眼鸟属(Zosterops)的亲缘关系、以及鹪莺属(Prinia)、缝叶莺属(Orthotomus)及扇尾莺属(Cisticola)三者间的亲缘关系也被支持.

Members of the passerine family Sylviidae are distributed widely around the Old World and the phylogenetic relationships of many species still remain controversial. In this study, we investigated the phylogeny and relationships among 37 species of 11 genera by analyzing DNA sequences obtained from the complete mitochondrial cytochrome b (cyt b) and partial cytochrome oxidase I (CO1) genes. The data were analyzed by maximum-likelihood analysis and Bayesian in-ference. The results demonstrate that the current genus Phylloscopus is non-monophyletic, while Seicercus is synonymized with Phylloscopus or is a group within the genus Phylloscopus. We may conclude that within Phylloscopus there are close relations between P magnirostris and P. borealis; among P. proregulus, P. yunnanensis, P pulcher and P maculipennis, as well as among P occisi-nensis, P. schwarzi, P. armandii, P. collybita and P. fuscatus. Monophyly of the genus Cettia could not be corroborated; it is closely related to the genera Abroscopus and Tesia. However monophyly of Acrocephalus is supported. Furthermore, the close relationships between Sylvia and Zosterops and among Prinia, Orthotomus and Cisticola are also supported.
