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

9978193马丁和雅各布斯虽然在物种数量上排名第三（仅次于昆虫和软体动物），但甲壳类动物是地球上形态上最多样化的动物群体。 洛杉矶县自然历史博物馆（LACM）拥有全国第二大甲壳类动物收藏，是甲壳类专题和系统学广泛培训的合理舞台。 地区大学，如加州大学洛杉矶分校提供了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整合的绝佳机会。 该项目支持学生培训和专题和系统研究甲壳类多样性的三个广泛领域，目前世界上缺乏专门知识：（1）薄甲目;（2）鳃甲目（Spinicaudata）;和（3）十足目（Xanthoidea总科）。 薄甲纲包含小型（6 - 15毫米）海洋食虫动物和具有巨大生态重要性和系统发育意义的食腐动物。 Conchostraca（蛤蜊虾）是鳃足纲的成员，这是一个古老的原始谱系，可以追溯到寒武纪中期;所有这些都局限于淡水短暂的池塘栖息地，因此是特别值得保护的物种。 在十足类甲壳动物中，很少有类群像以前的黄蟹科那样令人头疼。黄蟹科是一个庞大的短尾纲（真）蟹类组合，包含约130属，2,000多个物种。 我们的工作最初将限于“Carpiliid”线，其中大多数成员是在热带珊瑚礁上或附近发现的小型到大型螃蟹。 我们将在5年内培养三名博士生作为加州大学洛杉矶分校的研究生，与LACM策展人员共同工作。 由马丁在LACM监督的形态学系统和专题研究将由加州大学洛杉矶分校雅各布斯指导的分子遗传学研究补充。 受训者将通过在加州大学洛杉矶分校的正式课程和通过构建自己的专题网页，精通数据库管理和网站开发;每个学生将监督将在网上发布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.
