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）是最早飞行的动物之一，它们的翅膀是独一无二的。 它们的分布是世界性的，但许多分类群是受环境限制的，使它们成为优先保护地区的宝贵指标。 我们将分析蜻蜓目中尽可能多的亚科之间的进化关系，作为对该群体进行生物学研究的基础。我们将收集来自28 S rRNA、EF-1 α和线粒体基因以及形态学的DNA序列数据。将使用简约法和最大似然法分析数据。该项目将整合其参与者之间的各种不同背景。Kjer的专长是分子遗传学，并寻求利用形态系统学家的专业知识，并将其引入分子方法。 Frank Carle是一位有机体牙齿学家，强调独立形态特征之间一致性的价值。 梅有研究蜻蜓的生态和行为的经验。这项研究将培养一名非洲裔美国博士生杰西卡·韦尔和一名博士后。 除了她的科学培训，威尔女士还积极在纽瓦克和卡姆登学校系统工作，帮助招募学生从群体中历史上在科学代表不足，参加罗格斯大学。像恐龙和鸟类一样，蜻蜓和它们的进化史吸引了公众。 这本书将为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种飞行动物可能是什么样子的例子。 作为淡水生态系统的组成部分，蜻蜓是重要的水质指标。
