PEET: Crustacean Systematics: Monographic Research in the Leptostraca, Conchostraca, and Brachyura

9978193马丁和雅各布尽管甲壳类动物在物种数量上排名第三(仅次于昆虫和软体动物)，但它们是地球上形态最多样化的一类动物。洛杉矶县自然历史博物馆(LACM)拥有美国第二大甲壳类藏品，是甲壳类专题和分类学广泛基础培训的合乎逻辑的集散地。加州大学洛杉矶分校等地区大学提供了特殊的机会，将基于博物馆的专题和分类学研究与现代系统和分子实验室培训和课程工作相结合。该项目支持在目前世界上缺乏专门知识的三个甲壳类多样性的广泛领域进行学生培训和专题和系统研究：(1)细足目；(2)鳍足目(脊尾目)；和(3)十足目(蝙蝠总科)。Leptostraca含有小型(6-15毫米)海洋有害食肉动物和食腐动物，具有巨大的生态重要性和系统发育意义。贝类是枝足纲的一员，属于古老的原始世系，可追溯到中寒武世；它们都局限于淡水短暂的池塘栖息地，因此是特别受保护的物种。在十足类甲壳类动物中，没有几个类群像前一科珊瑚科那样麻烦，这是一个巨大的短毛蟹(真)蟹群，包含约130个属和2000多个物种。我们的工作最初将限于“Carpiliid”线，其中大多数成员是热带珊瑚礁上或附近发现的小到大的螃蟹。我们将与加州大学洛杉矶分校的策展人员合作，在5年内培养三名博士生成为加州大学洛杉矶分校的研究生。加州大学洛杉矶分校的马丁负责的形态、系统和专题研究将得到加州大学洛杉矶分校雅各布斯指导的分子遗传学研究的补充。学员将通过加州大学洛杉矶分校的正式课程和构建自己的专著网页，精通数据库管理和网站开发；每个学生都将监督将发布在网上的关系数据库的创建。

9978193 Martin and JacobsAlthough third in number of species (behind insects and molluscs), crustaceansare the most morphologically diverse group of animals on earth. The NaturalHistory Museum of Los Angeles County (LACM) contains the country's secondlargest collection of crustaceans and is a logical staging area for broad-based training in crustacean monography and systematics. Area universities such as UCLA offer exceptional opportunities for the integration of museum-based monographic and taxonomic research with modern systematic and molecular laboratory training and coursework. This project supports student training and monographic and systematic research in three broad areas of crustacean diversity where current world expertise is lacking: (1) the order Leptostraca; (2) the branchiopod order Conchostraca (Spinicaudata); and (3) the infraorder Decapoda (superfamily Xanthoidea). The Leptostraca contains small (6-15 mm) marine detritivores and scavengers of tremendous ecological importance and phylogenetic significance. The Conchostraca (clam shrimp) are members of the class Branchiopoda, an ancient and presumed primitive lineage extending back to the middle Cambrian; all are restricted to freshwater ephemeral pond habitats and are thus species of special conservation concern. Among the decapod crustaceans, few groups are as troublesome as the former family Xanthidae, an enormous assemblage of brachyuran (true) crabs that contains some 130 genera and well over 2,000 species. Our work will be restricted initially to the "Carpiliid" line, most members of which are small to large crabs found on or near tropical reefs. We will train three doctoral students over a 5-year period as graduate students of UCLA, working jointly with LACM curatorial staff. Morphological systematic and monographic research overseen by Martin at LACM will be complemented by molecular genetic studies guided by Jacobs at UCLA. Trainees will become well versed in database management and web sitedevelopment via formal coursework at UCLA and through the construction of their own monograph web pages; each student will oversee the creation of arelational database that will be posted on the web.
