1裂腹鱼类种质多样性研究综述显示文摘裂腹鱼类隶属于鲤形目鲤科裂腹鱼亚科,目前已记录有12属90种(亚种),是鲤科鱼类中为数不多的适应于亚洲中部青藏高原地区自然条件的一个自然类群。整个裂腹鱼类呈现出以青藏高原为中心的分布格局,中国是世界上裂腹鱼类种类分布最多的国家。目前,随着对鱼类种质资源研究越来越受到人们的关注,裂腹鱼类作为产地名贵经济鱼类,其种质资源已成为了研究的热点。主要从形态分类、物种多样性、地理分布、细胞水平、生化水平和分子水平等,对多年来裂腹鱼类种质资源研究方面的进展进行了综述,以期为裂腹鱼类资源的保护和利用提供基础资料。代应贵 肖海 2011中国农学通报2011,27,32:27
2Pliocene cyprinids (Cypriniformes,Teleostei) from Kunlun Pass Basin,northeastern Tibetan Plateau and their bearings on development of water system and uplift of the area显示文摘Here described are the cyprinid fossils from the Pliocene Lower Member of Qiangtang Formation of the Kunlun Pass Basin,northeastern Tibetan Plateau,collected at a locality 4769 m above the sea level(asl).The materials consist of numerous disarticulated and incomplete bones as well as thousands of pharyngeal teeth,fin rays,and vertebrae.The fossils were referred to the genus Gymnocypris,lineage Schizothoracini,family Cyprinidae;the lineage Schizothoracini;and the family Cyprinidae respectively.The Schizothoracini is a freshwater fish group endemic to the Tibetan Plateau and its surrounding area.Previous workers on living schizothoracins regarded that Gymnocypris belongs to the highly specialized grade of the group,colonizing higher altitudes than other members of the group.Two species are so far unequivocally assigned to the genus,i.e.,G.przewalskii and G.eckloni,and they are inhabiting Qinghai Lake and the waters on both north(the Golmud River) and south(upper reach of the Yellow River) sides of the East Kunlun Mountain,respectively.The abundant fossil schizothoracins occur in the Kunlun Pass Basin on the southern slope of the East Kunlun Mountain(at 4769 m asl),close to the present Golmud River,indicating comparatively rich waters in the area and possible connections between the water systems on north and south sides of the East Kunlun Mountain during the Pliocene.This also suggests a more humid climate in the area during the Pliocene than it is today.The presence of the highly specialized schizothoracin Gymnocypris may also imply less amplitude of uplift(approximately 1000 m) in the area since the Pliocene than previously proposed.CHANG Mee-mann 2010Science China Earth Sciences2010,53,4:8
3Molecular phylogeny of European and African Barbus and their West Asian relatives in the Cyprininae(Teleostei:Cypriniformes)and orogenesis of the Qinghai-Tibetan Plateau显示文摘The phylogenetic relationships of European and African Barbus and their West Asian relatives in Cyprininae remain largely unresolved.Consequently,little is known about the drivers of their evolution,including the possible association of uplifting of the Qinghai-Tibetan Plateau(QTP)with the early divergence of the subfamily.We use complete sequence data of the mitochondrial DNA gene encoding the protein cytochrome b(Cytb)to hypothesize the phylogeny of 85 species belonging to 47 genera in the Cyprininae plus 6 species from the Leuciscinae.We employ 6 other species from Cypriniformes as outgroup taxa and estimate divergence times.Our results indicate that European Barbus sensu stricto lineage including Aulopyge shares a common ancestor with specialized and highly specialized schizothoracins and the genera Cyprinion and Scaphiodonichtys.The common ancestor appears to have originated in the Qinghai-Tibetan Plateau(QTP)region about 19.4–17.8 Ma.Barbus sensu stricto lineage appears to have originated about 16.6–15.5 Ma.Small to medium sized African Barbus sensu lato appear to have had an Oriental origin about 19.1–15.3 Ma and are closely related to Asian Puntius.West Asian Carasobarbus lineage including large African Barbus sensu lato might have originated about 9.94 Ma,also in Oriental Realm and has a close relationship to Asian Neolissochilus and Tor.The large-sized Barbus sensu lato appear to have diverged from Carasobarbus about 7.7 Ma.Finally,the Cyprininae appear to have radiated rapidly into nine lineages and many sublineages from about 27.8 to 17.8 Ma,close to the time of the second-stage tectonic movements of the QTP.Our analyses provide evidence that the uplifting of the QTP drove early diversification of the Cyprininae.Our extensive sampling of species involving all of the important areas results in clear evolutionary scenario for the Cyprininae.WANG Jing WU XiaoYun CHEN ZiMing YUE ZhaoPing MA Wei CHEN ShanYuan XIAO Heng MURPHY Robert W ZHANG YaPing ZAN RuiGuang LUO Jing 2013Chinese Science Bulletin2013,58,31:0
