Odonata (dragonflies and damselflies) were among the first animals to fly, and their wings are unique. Their distribution is world-wide, yet many taxa are environmentally confined, making them valuable indicators of areas of priority for conservation. We will analyze evolutionary relationships among as many subfamilies of Odonata as possible, as a foundation for biological work on the group. We will collect DNA sequence data from 28S rRNA, EF-1alpha, and mitochondrial genes as well as morphology. Data will be analyzed using parsimony and maximum likelihood methods. The project will integrate a variety of differing backgrounds among its participants. Kjer's expertise is in molecular phylogenetics, and seeks to utilize the expertise of morphological systematists and introduce them to molecular methods. Frank Carle is an organismal odonatologist, stressing the value of concordance between independent morphological characters. May has experience studying the ecology and behavior of Odonata. The study will train an African-American doctoral student, Jessica Ware, and a postdoctoral associate. In addition to her scientific training, Ms. Ware is actively working in the Newark and Camden School systems to help recruit students from groups historically underrepresented in science to attend Rutgers. Like dinosaurs and birds, dragonflies and their evolutionary history appeal to the public. This phylogeny will provide a framework for discussing these organisms with the public and give us an example of what the first animal on earth to fly might have looked like. As integral components of freshwater ecosystems, Odonata are important as indicators of water quality.

蜻蜓（蜻蜓和豆娘）是最早会飞的动物之一，它们的翅膀是独一无二的。它们分布在世界各地，但许多分类群受到环境限制，使它们成为优先保护地区的宝贵指标。我们将分析尽可能多的蛇蜥亚科之间的进化关系，作为对该群体的生物学工作的基础。我们将收集28S rRNA、EF-1alpha和线粒体基因以及形态学的DNA序列数据。数据将使用简约和最大似然方法进行分析。该项目将整合不同背景的参与者。kker的专长是分子系统发育，并寻求利用形态系统学家的专业知识，并将他们引入分子方法。弗兰克·卡尔是一位有机体牙学家，他强调独立形态特征之间的一致性的价值。梅有研究蛇蜥的生态学和行为的经验。这项研究将培养一名非裔美国博士生杰西卡·韦尔（Jessica Ware）和一名博士后。除了接受科学培训外，韦尔还积极在纽瓦克和卡姆登学校系统中工作，帮助从历史上在科学领域代表性不足的群体中招募学生进入罗格斯大学。像恐龙和鸟类一样，蜻蜓和它们的进化史吸引着公众。这种系统发育将为与公众讨论这些生物提供一个框架，并为我们提供一个地球上第一个会飞的动物可能长什么样的例子。河豚是淡水生态系统的重要组成部分，是水质的重要指标。
