| 摘要: |
| 裂腹鱼类是分布于青藏高原及其周边地区的一群鲤科鱼类，随着青藏高原的隆升由原始的鲃亚科鱼类逐渐演化为适应于寒冷、高海拔和急流等恶劣环境的一个自然类群，其共同特征是肛门和臀鳍基部两侧各有一列特化的鳞片（臀鳞），具有生长缓慢、性成熟晚、寿命较长、繁殖力低等生活史特征。裂腹鱼类是四倍体起源，多倍体化事件在其进化过程中发挥了重要的作用。裂腹鱼类特殊的地理分布、形态特征、遗传结构和生活史对策使其成为研究多倍体鱼类和高原适应机制的重要材料，并受到科学家们的广泛关注。本文综合分类学、系统发育与生物地理学、遗传学和生物学等领域，重点从考古学和系统学等多角度对裂腹鱼类的起源与进化进行论述，基于转录组学阐述裂腹鱼类高原适应的分子机制，较为全面地总结了高原多倍体鱼类的系统进化及极端环境适应。 |

| Abstract: |
| Schizothoracine fishes are distributed in the Qinghai-Tibet Plateau and its surrounding areas. With the uplift of Qinghai-Tibet Plateau, the primitive Barbinae fishes gradually evolved into schizothoracine fishes, adapting to severe environment such as cold, high altitude and fast flow. Schizothoracine fishes share the morphological trait that specialized scales (anal scales) distribute on each side of the anal and anal fin bases. Schizothoracine fishes characterize with slow growth, late sexual maturity, long life-span and low fecundity. Schizothoracine fishes originate from tetraploid organism, and polyploidy events are the key factors driving their evolution. The special geographical distribution, morphological characteristics, genetic structure and life-history strategy of schizothoracine fishes have made them important materials for the study of polyploid and plateau adaptation mechanism, and have received extensive attentions from scientists. Combining with taxonomy, phylogeny and biogeography, genetics and biology, this paper focused on interpreting the systematic evolution of schizothoracine fishes from the perspective of modern archaeology and molecular biology, revealing the molecular mechanism of plateau adaptation in schizothoracine fishes from the transcriptome study. The aim of this study is to provide reference for the systematic evolution of polyploid fishes and the mechanism of extreme environmental adaptation in plateau. |
