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，是甲壳类动物专论和系统学广泛培训的合理集结地。像加州大学洛杉矶分校这样的地区大学提供了难得的机会，将以博物馆为基础的专题和分类学研究与现代系统的分子实验室培训和课程结合起来。该项目支持学生培训，并在目前世界缺乏专业知识的三个甲壳类动物多样性广泛领域进行专题和系统研究：(1)细肢目；(2)棘足目棘足目；(3)下十足目（黄总科）。细肢象包括小型（6-15毫米）海洋腐食动物和食腐动物，具有巨大的生态重要性和系统发育意义。蛤虾（蛤虾）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；所有的物种都局限于淡水的短暂池塘栖息地，因此是特别保护的物种。在十足甲壳类动物中，很少有像前一科黄蟹科那样麻烦的，黄蟹科是一个巨大的短爪蟹（真正的）集合，包含大约130属，超过2000种。我们的工作最初将局限于“Carpiliid”系列，其中大多数成员是在热带珊瑚礁或附近发现的小型到大型螃蟹。我们将在5年内培养3名博士研究生成为UCLA的研究生，与LACM策展人员共同工作。由LACM的Martin指导的形态学系统和专题研究将由加州大学洛杉矶分校的Jacobs指导的分子遗传学研究补充。通过加州大学洛杉矶分校的正式课程和建立自己的专题网页，学员将精通数据库管理和网站开发；每个学生将监督关系数据库的创建，该数据库将发布在网络上。

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.
