Abstract

Sequencing the complete mitochondrial genome of four individuals of two subspecies of black-billed capercaillie Tetrao parvirostris parvirostris (mainland population) and T. p. kamtschaticus (Kamchatka Peninsula), family Tetraonidae, was arranged for the first time. Genetic divergence between mainland and Kamchatka subspecies was estimated as 0.1%, which corresponds to the level of individual variability. Compared to high haplotype diversity, a low nucleotide polymorphism of mtDNA was revealed and absence of inter-subspecies genetic differentiation was shown. Such absence may reflect the youth of the Kamchatka isolate and/or conservation of the mitochondrial genome for the species as a whole. Analysis of a fragment of the nuclear gene OCA2, encoding the transmembrane P protein and affecting the coloration, revealed the identity of the subspecies of mainland and Kamchatka. Such a clear lack of divergence by mitochondrial and nuclear markers between the mainland and Kamchatka populations of the capercaillie contradicts their morphological differences. Appearance of an isolated population of the black-billed capercaillie in Kamchatka was probably caused by either shrinking of the mainland part of formerly large range of the species that created the gap, or recent invasion from the mainland.

摘要

测序完整的线粒体基因组的四个个体的黑嘴雀毛的四个亚种Tetrao parvirostris parvirostris（大陆人口）和TP 。四足纲科的kamtschaticus（堪察加半岛）是第一次被安排。大陆和堪察加亚种之间的遗传差异估计为0.1％，这与个体变异水平相对应。与高单倍型多样性相比，揭示了mtDNA的低核苷酸多态性，并显示了亚种间遗传分化的缺失。这种缺乏可能反映了堪察加分离株的年轻和/或整个物种线粒体基因组的保守性。核基因OCA2片段的分析编码跨膜P蛋白并影响其颜色，揭示了大陆和堪察加半岛亚种的身份。内地和堪察加人的堪察加半岛人群之间线粒体和核标记物之间明显缺乏差异，这与它们的形态差异相矛盾。在堪察加半岛出现的一头黑嘴猴的出现可能是由于原先形成该缺口的大范围物种的大陆部分萎缩，或者是最近从该大陆入侵造成的。
