Abstract

The mitochondrial pseudo-control region was analysed in five species of Aquila eagles. Indels caused great length differences in the nonrepetitive part of the region, whereas tandem repeat units were highly conserved among the genus. In a reconstructed phylogenetic tree, the clade formed by A. clanga and A. pomarina showed approximately the same distance to A. chrysaetos as did the clade A. heliaca/nipalensis. In Estonian subpopulations, 12 haplotypes were found among 51 A. pomarina individuals and 7 haplotypes among 8 A. clanga individuals. Nucleotide diversity in A. clanga was greater, and may be caused by decreased breeding density or by gene flow from other subpopulations.

摘要

对五种鹰属鹰类的线粒体假控制区进行了分析。插入缺失导致该区域非重复部分的长度差异很大，而串联重复单元在该属中高度保守。在重建的系统发育树中，白腹鹞和乌灰鹞形成的分支与金雕的距离与白肩雕/高山兀鹫分支与金雕的距离大致相同。在爱沙尼亚亚种群中，51只乌灰鹞个体中发现了12种单倍型，8只白腹鹞个体中发现了7种单倍型。白腹鹞的核苷酸多样性更大，这可能是由于繁殖密度降低或其他亚种群的基因流动所致。
