棕颈钩嘴鹛分子系统发育及分类关系初探

Preliminary discussion on the phylogenetic and taxonomic relationship of Pomatorhinus ruficollis

  • 摘要: 棕颈钩嘴鹛(Pomatorhinus ruficollis)各亚种间系统发育关系一直存在分歧。该文测定了棕颈钩嘴鹛10个亚种20个样本的完整线粒体Cyt b和ND2基因序列(共2 184 bp), 以棕颈钩嘴鹛(P. ruficollis)和灰头钩嘴鹛(P. schisticeps)为内群; 栗背钩嘴鹛(P. montanus)、棕头钩嘴鹛(P. ochraceiceps)、红嘴钩嘴鹛(P. ferruginosus)和剑嘴鹛(Xiphirhynchus superciliaris)为外群, 通过最大简约法、最大似然法以及贝叶斯推断法, 构建了棕颈钩嘴鹛亚种间的系统发育树。结果显示:棕颈钩嘴鹛是并系群, 灰头钩嘴鹛聚合在其内部; 棕颈钩嘴鹛可分为3个地理支序, 即中国西南部支序、中国东南部支序和中国中部支序;棕颈钩嘴鹛亚种间系统发育关系与形态特征不完全一致, 并澄清了一些分类问题。

     

    Abstract: The phylogenetic relationships among subspecies of Pomatorhinus ruficollis are not clear. In this paper we sequenced two mitochondrial genes (Cyt b and ND2, in total 2 184 bp) and examined twenty individuals representing ten of the eleven subspecies of P. ruficollis in China.Molecular phylogenetic trees were reconstructed using maximum parsimony, maximum likelihood and Bayesian inference methods, with P. ruficollis and P. schisticeps as in-groups, P. montanus, P. ochraceiceps, P. ferruginosus and Xiphirhynchus superciliaris as out-groups. Results indicated that P. ruficollis was paraphyletic, in which P. schisticeps was embedded, and was divided into three phylogeographic groups: southwestern China group, southeastern China group and central China group. Our results also suggested discordances between phylogenetic relationships and morphological characteristics, and clarified some intraspecific taxonomic debates.
