A Multi-Gene Phylogeny of Scallops (Mollusca: Bivalvia: Pectinidae) and an Examination of Morphological and Behavioral Trait Evolution

扇贝科扇贝是一种多样化的海洋双壳类动物，包括300多种。作为一个群体，扇贝支持着重要的渔业，是全世界贝类养殖的重点。这个家族的成员在游泳和繁殖方式等行为上表现出很大的差异。尽管扇贝具有有趣的生物学和经济重要性，但人们对其多样性和进化关系知之甚少。本研究项目的目标是：1)利用DNA序列和形态数据对扇贝的进化关系提出假设；2)建立反映这些关系的稳定的扇贝分类；3)利用这些信息更好地了解扇贝的形态特征、行为和生活史特征的演变。通过这项研究，将对进化过程的一个基本组成部分——复杂字符的起源——获得重要的见解。此外，本工作将为一名博士后、研究生和本科生提供现代系统处理扇贝生产过程中所有活动的培训。除了同行评议的出版物和在科学会议上传播结果外，还将开发一个互动式网络资源（Pecten资源网站），从而改善包括扇贝养殖者、软体动物学家、进化生物学家、生态学家和贝壳爱好者在内的广泛用户之间的交流。

Scallops in the family Pectinidae are a diverse group of marine bivalves that includes over 300 species. As a group, scallops support important fisheries and are the focus shellfish farming operations worldwide. Members of the family exhibit wide variation in such behaviors as swimming and mode of reproduction. Despite their interesting biology and economic importance, scallop diversity and evolutionary relationships are poorly understood. The goals of this research project are to: 1) generate hypotheses for the evolutionary relationships of scallops using DNA sequence and morphological data; 2) develop stable classification of scallops reflective of these relationships; and 3) use this information to better understand the evolution of scallop morphological characters, behaviors, and life history traits.Through this research, important insight will be gained into a fundamental component of the evolutionary process: the origin of complex characters. In addition, this work will provide training to a postdoctoral associate and graduate and undergraduate students in all activities during the production of a modern systematic treatment scallops. Besides peer-reviewed publications and dissemination of results at scientific meetings, an interactive web-based resource (the Pecten Resource Web Site) will be developed, thus improving communication among a wide range of users, including scallop farmers, malacologists, evolutionary biologists, ecologists, and shell enthusiasts.
