摘要

根据分子系统发育分析，包括在Carduelini部落(Rhodopechys属，Carpodacus属和Leucosticte属)内的鸟类显然对相同的辐射很长。我们基于细胞色素b基因(cyt-b)核苷酸序列的系统发育分析表明，其中一些鸟类(Rhodopechys mongolica, R. githaginea和Carpodacus nipalensis)与它们各自的表型定义的亲缘关系不聚集在一起。这种新的鸟类在炎热和寒冷的干旱地区都能茁壮成长，并且在表型上是不同的，可能是因为它们适应了不同的极端环境。最大似然和贝叶斯推理方法都支持这一新的雀类进化基础群的存在，它可能起源于大约1400万年前。

Mitochondrial DNA Phylogenetic Definition of a Group of 'Arid-Zone' Carduelini Finches

Birds included within the Carduelini tribe (genera Rhodopechys, Carpodacus and Leucosticte) apparently be- long to the same radiation according to molecular phylogenetic analyses. Our phylogenetic analyses based on nucleotide sequences of the cytochrome b gene (cyt-b) indicate that some of these birds (Rhodopechys mongolica, R. githaginea and Carpodacus nipalensis) do not cluster together with their respective phenetically defined allies. This new group of birds thrives in both hot and cold arid zones and are phenetically distinct, probably because of their adaptation to different ex- treme environments. Both maximum likelihood and Bayesian inference methods support the existence of this new evolu- tionary basal group among finches which might have originated about 14 million years ago.

期刊介绍： The Open Ornithology Journal is an Open Access online journal, which publishes research articles, reviews/mini-reviews, letters and guest edited single topic issues in all important areas of ornithology including avian behaviour,genetics, phylogeography , conservation, demography, ecology, evolution, and morphology. The Open Ornithology Journal, a peer-reviewed journal, is an important and reliable source of current information on developments in the field. The emphasis will be on publishing quality papers rapidly and making them freely available to researchers worldwide.
