淡水类群的分布是研究地理迁移和扩散格局和过程的一个很好的地理模型。雅罗鱼亚科（Leuciscinae）是一个广泛分布于欧亚大陆和北美洲的鱼类亚科。银合欢亚科分为两个系统群，银合欢素和phoxinin。该亚科内主要分支之间的系统发育关系知之甚少，主要是因为该群体的压倒性多样性。远东phoxinin的起源是一个有趣的问题，关于Leuciscinae的进化历史。本文基于线粒体基因组全序列对31种银汉鱼亚科及其外类群进行系统发育分析，以阐明该亚科的系统发育关系，并推测其进化历史。系统发育分析表明，远东地区的phoxinin种由Tribolodon、Pseudaspius、Oreoleuciscus和Far Eastern Phoxinus组成。远东phoxinin分支是独立的其他Leuciscinae谱系，更接近北美phoxinins比欧洲leuciscins。我们所有的分析还表明，leuciscins和phoxinins每个构成单系群。分歧的时间估计表明，Leuciscinae物种从外群，如Tincinae分化为8.33亿年前（Mya）在晚白垩世和leuciscin和phoxinin共享一个共同的祖先70.7 Mya。银汉鱼亚科的辐射发生在晚白垩世至古新世。这一时期也见证了四足动物的辐射。重建的祖先地区表明，Leuciscinae物种起源于欧洲。Leuciscin物种在欧洲进化，phoxinin的祖先分布在北美。远东的phoxinins可能是通过白令吉亚陆桥从北美扩散到远东的。本研究表明，晚白垩世大陆的重新排列对形成现今生物分布具有重要作用。此外，晚白垩世生物周转对现代陆地生物多样性也有影响。(C)2012爱思唯尔有限公司版权所有。
The distribution of freshwater taxa is a good biogeographic model to study pattern and process of vicariance and dispersal. The subfamily Leuciscinae (Cyprinidae, Teleostei) consists of many species distributed widely in Eurasia and North America. Leuciscinae have been divided into two phyletic groups, leuciscin and phoxinin. The phylogenetic relationships between major clades within the subfamily are poorly understood, largely because of the overwhelming diversity of the group. The origin of the Far Eastern phoxinin is an interesting question regarding the evolutionary history of Leuciscinae. Here we present phylogenetic analysis of 31 species of Leuciscinae and outgroups based on complete mitochondrial genome sequences to clarify the phylogenetic relationships and to infer the evolutionary history of the subfamily.Phylogenetic analysis suggests that the Far Eastern phoxinin species comprised the monophyletic clades Tribolodon, Pseudaspius, Oreoleuciscus and Far Eastern Phoxinus. The Far Eastern phoxinin clade was independent of other Leuciscinae lineages and was closer to North American phoxinins than European leuciscins. All of our analysis also suggested that leuciscins and phoxinins each constituted monophyletic groups. Divergence time estimation suggested that Leuciscinae species diverged from outgroups such as Tincinae to be 833 million years ago (Mya) in the Late Cretaceous and leuciscin and phoxinin shared a common ancestor 70.7 Mya. Radiation of Leuciscinae lineages occurred during the Late Cretaceous to Paleocene. This period also witnessed the radiation of tetrapods. Reconstruction of ancestral areas indicates Leuciscinae species originated within Europe. Leuciscin species evolved in Europe and the ancestor of phoxinin was distributed in North America. The Far Eastern phoxinins would have dispersed from North America to Far East across the Beringia land bridge. The present study suggests important roles for the continental rearrangements during the Late Cretaceous to form the present-day distribution of organisms. Furthermore, the Late Cretaceous biotic turnover influenced for the modern terrestrial biodiversity. (C) 2012 Elsevier B.V. All rights reserved.
