| 摘 要： | 以线粒体DNA细胞色素b基因的全序列作为遗传标记 ,探讨红喉姬普通亚种 (Ficedulaparvaal bicilla)和指名亚种 (F .p .parva)的分类地位。应用Kimura 2 parameter法计算出红喉姬普通亚种个体间的遗传距离为 0 1%～ 0 2 % ,而与指名亚种之间的遗传距离为 6 4 % ,两亚种之间的遗传距离远远大于种间的遗传距离。结合形态学的特征我们认为 :红喉姬指名亚种和普通亚种应为两个独立种 ,分别为红喉姬 (F .albicilla)和红胸姬 (F .parva) ,两者的分化时间为 3 15～ 3 2 5百万年

| Abstract: | It was disputed that Ficedula parva parva and F.p.albicilla were two species or two subspecies.Complete sequences of mitochondrial cytochrome b gene were used as a genetic marker to study the taxonomic status of them.The genetic distance between F.p.albicilla and F.p.parva was 6 3% based on the Kimura's two Parameter's method,which was far more than the genetic distance between other species of Ficedula .The results suggest that F.p.albicilla and F.p.parva should be two species,their names are F.albicilla and F.parva separately,and the divergence time between F.p.albicilla and F.p.parva is 3 15 to 3 25 My. |
