AToL: Collaborative Research: Systematics of Cypriniformes, Earth's Most Diverse Clade of Freshwater Fishes

知识价值--这项研究将制定鲤形目鱼类的系统发育和分类，鲤形目鱼类是世界上最大的一组已描述的全淡水鱼，有3,285种，以及多达2,600种未描述的物种。这一类包括小鱼、吸鱼、泥鳅、河流泥潭和食藻动物。这些鱼类中有许多具有重要的经济和科学价值。几种大型鲤鱼是亚洲重要的蛋白质来源，矛盾的是，它们是北美令人讨厌的入侵物种。斑马鱼是发育生物学家的模式生物；愚头鱼被用作环境工作的指示物种；金鱼被生理学家广泛研究。许多物种是由水族饲养的，这项爱好对教育和经济都有巨大的影响。我们的项目是国际范围的，有27个合作者，包括来自全球的一些最著名的鲤科动物系统学家。该小组包括古生物学家、新生物学家、发育生物学家和分子系统学家。我们将利用一系列核和线粒体基因的基因组数据，包括完整线粒体基因组的子集以及化石和现存物种的形态数据，建立系统发育图。更广泛的影响--系统发展史，包括发育信息，将扩大基于斑马鱼和其他模式物种的工作范围，并将产生稳定的分类。我们将描述新物种，扩大我们对生物多样性的理解。我们的研究不仅对学生进行系统学、进化论、生物多样性、发育和形态方面的教育，国际合作，以及关于斑马鱼、愚头鱼和金鱼等模式生物的关键信息，还具有重大的更广泛的影响。首席调查员和联合首席调查员从不同机构(3所私立大学和4所公立大学；4所公立大学；其中4所在EPSCoR辖区)聘请了处于许多职业阶段的不同科学家群体(10人中有2人是女性；10人中有2人是少数民族；10人中有2人有肢体残疾；10人中有5人是新调查人员)。将制作一个Nova电视节目，并举行公开会议。信息将通过项目门户网站(http://bio.slu.edu/mayden/cypriniformes/projects.html)和传统科学出版物传播。

Intellectual Merit - This study will develop a phylogeny and classification for the fishes of the Order Cypriniformes, the largest group of entirely freshwater fishes in the world with 3,285 described, and as many as 2,600 undescribed species. This group contains the minnows, suckers, loaches, river loaches and algae eaters. Many of these fishes have economic and scientific importance. Several large carp are an important protein source in Asia, and paradoxically, are nuisance, invasive species in North America. The zebrafish is a model organism for developmental biologists; the fathead minnow is used as an indicator species in environmental work; and goldfish are widely studied by physiologists. Many species are kept by aquarists, a hobby that has vast educational and economic impacts. Our project is international in scope with 27 collaborators, including some of the most prominent cypriniform systematists from across the globe. The group includes paleontologists, neontologists, developmental biologists, and molecular systematists. We will develop phylogenies using genomic data for a set of nuclear and mitochondrial genes, including a subset of complete mitochondrial genomes as well as morphological data from fossil and extant species. Broader Impacts - The phylogeny, including the developmental information, will broaden the scope of work based on the zebrafish and other model species, and will produce a stable classification. We will describe new species, expanding our understanding of biodiversity. Our study has significant broader impacts beyond pure research with student education in systematics, evolution, biodiversity, development, and morphology, international collaboration, and critical information on model organisms like the zebrafish, fathead minnow, and goldfish. The prncipal and co-principal investigators reresent a diverse group of scientists at many career stages (2 of 10 are female; 2 of 10 are minorities; 2 of 10 have physical disabilities; 5 of 10 are new investigators) and come from diverse institutions (3 private universities and 4 public universities; 4 of the institutions are in EPSCoR jurisdictions). A NOVA television program will be produced and public meetings will be held. Information will be disseminated via a project web portal (http://bio.slu.edu/mayden/cypriniformes/projects.html) as well as conventional scientific publication.
