雪雀属系统发育关系的研究(雀形目:文鸟科)

PHYLOGENY OF SPECIES OF MONTIFRINGILLA BASED ON CLADISTIC (PASSERIFORM: PLOCEIDAE)

雪雀属Montifringilla 7种 36个形态特征作为分类单元 ,进行支序分析。以麻雀属Passer、石雀属Petronia部分种类作为比较外群 ,讨论雪雀属的分类地位及其与近缘属麻雀属、石雀属系统发育关系 ;分析了雪雀属内种间的系统发育。支序分析的结果表明雪雀属为单系群 ,建议将雪雀属划分成两个亚属 ,讨论了雪雀属种类在进化上的位置。在 3个近缘属的系统发育关系中 ,麻雀属类群较原始 ,雪雀属类群较进化 ,石雀属在进化中介于二者之间。

This paper dealt with phylogenetic relationships among species in Montifringilla by cladistic approach based on 36 morphological characters, while Passer domestic, P montanus and Petronia petronia were also compared as out groups The results of analysis support that the monophyletic group of Montifringilla might be divided into two groups: Montifringilla and Pyrgilauda,and suggest that these two groups should be treated as subgenera rather than genera The relationships among seven species of Montifringilla are also discussed As to the phylogenetic relationships of the three related genera, Passer is the most primitive genus and Montifringilla is the most derived genus, while Petronia is intermediate between them
