摘要
采用PCR扩增、测序的方法,对鹟亚科(Muscicapinae)6属16种鸟类的线粒体COI基因序列1 176 bp进行测定,并以荒漠伯劳和发冠卷尾作为外群构建Bayes、ML、MP 3棵系统发育树.结果支持:寿带属(Terpsiphone)、扇尾鹟属(Rhipidura)、方尾鹟属(Culicicapa)3属与鹟亚科其他鸟类亲缘关系较远,扇尾鹟属与方尾鹟属亲缘关系较近;鹟属(Muscicapa)为单系发生,本研究结果未能确定它与仙鹟属、姬鹟属的进化关系;铜蓝鹟(Muscicapa thalassina)从鹟属中移出,归入仙鹟属.上述结论解决了鹟亚科部分属间的进化关系,为鹟亚科分类系统的研究提供了分子水平证据.
Abstract
This paper investigates phylogenetic relationships within the Muscicapinae based on analysis of cytochrome oxidase I mitochondrial gene sequences (1 176 bp). Sixteen species representing six of eight putative Muscicapinae genera were analysed, and Dicrurus hottentottus and Lanius isabellinus were selected as outgroups. Phylogenetic trees were reconstructed using the Bayesian ( BI) , maximum-likelihood ( ML) and maximum parsimony ( MP) methods. The results suggest that Terpsiphone, Rhipidura and Culicicapa are distant relatives of the other genera of Muscicapinae, and Rhipidura is a close relative of Culicicapa. Muscicapa is a monophyletic taxon, but the phylogenetic relationships of Muscicapa, Niltava and Ficedula are still uncertain. Our results suggest that Muscicapa thalassina should be placed in Niltava. These results resolve the phylogenetic relationships among some genera of Muscicapinae and provide some molecular phylogenetic evidence for taxonomic research of Muscicapinae.
