This dissertation will establish the phylogeny of Eunicidae, test the monophyly ofthe family and its genera, and analyze ontogenetic and along-the-body variation offeatures. We will use multiple sources of evidence - molecules, morphology anddevelopment - to produce more informative hypotheses of primary homology andconsequently a more robust phylogeny. This will allow us to revise Eunicidae and itsgenera and to test the phylogenetic content of traditional polychaete morphologicalcharacters. It will also offer a background for future phylogenetic studies of annelidsconcerned with similar issues of homology of highly modified, variable or seriallyrepeated structures.We request funding for Ms. Silva to conduct developmental studies using specificstaining and confocal microscopy at the Smithsonian's Fort Pierce lab, and to travel toDr. Ken Halancych's lab (Auburn University) in order to learn molecular techniquesspecific to annelids. This funding will allow us to expand the project from one that usestraditional anatomical characters and molecular markers to a more robust studyincorporating ontogeny and new genetic characters.Broader impacts: This study will train a graduate student in developmental andmolecular genetics of annelids, and strengthen ties between labs at George WashingtonUniversity, Smithsonian Institution, and Auburn University.

本论文将建立凤蝶科的系统发育，检验凤蝶科及其属的单系性，分析个体发育和沿体性状的变异。我们将使用多种证据来源-分子，形态学和发展-产生更多的信息假说的主要同源性，从而更强大的同源性。这将使我们能够修订Eunicidae及其属，并测试传统多毛类形态特征的系统发育内容。它也将为未来的环节动物系统发育研究提供一个背景，这些研究涉及高度修饰、可变或连续重复结构的同源性的类似问题。我们请求资助席尔瓦女士在史密森尼的皮尔斯堡实验室使用特异性染色和共聚焦显微镜进行发育研究，并前往华盛顿大学的博士。为了学习环节动物特有的分子技术，他在奥本大学的Ken Halancych实验室工作。这笔资金将使我们能够将该项目从一个使用简单的解剖特征和分子标记的项目扩展到一个更强大的研究，将个体发育和新的遗传特征结合起来。更广泛的影响：这项研究将培养一名环节动物发育和分子遗传学的研究生，并加强乔治华盛顿大学、史密森学会和奥本大学实验室之间的联系。
