The goal of this project is to conduct a thorough study of the pattern of spread of the cicadas, deducing how it has formed new species and colonized new areas over time. This colonization will be understood using DNA data to build evolutionary-trees and assign dates to branching events (past speciation). Results will be viewed against the backdrop of past climate change. Cicadas are excellent models for this type of study because they occur worldwide, their courtship songs make them easy to collect and identify, and their sedentary life histories generally result in clear boundaries between species. This research will aid in the establishment of a better taxonomy of cicada species and help catalog and understand the earth?s rapidly disappearing biodiversity.Because this project involves researchers in the US, China, Australia, New Zealand, Slovenia, France, the Netherlands, and South Africa, it will promote the international exchange of ideas and technology as well as specimens. This research will address a broad range of important questions, such as how climate change affects speciation and the application of information on mechanisms of molecular change over time to molecular tree-building. Species new to science will certainly be discovered. This research will contribute to the training of undergraduate, graduate, and postdoctoral researchers including under-represented groups. The results of this research will be made available through our website and will include an electronic field guide with distributions of collected cicada species and photographs and songs of many species. The website will also provide an updated list of world cicada workers, status of world cicada taxonomy research, links to other cicada sites, three large web-searchable databases (Magicicada, NZ cicadas and World Cicadas), lists of locations of types, maps, phylogenetic trees, locality guides, and more.

该项目的目标是对蝉的传播模式进行彻底的研究，推断它如何随着时间的推移形成新的物种并殖民新的地区。 这种殖民化将使用DNA数据来构建进化树并为分支事件（过去的物种形成）分配日期。将在过去气候变化的背景下看待结果。蝉是这类研究的绝佳模型，因为它们遍布世界各地，它们的求偶歌曲使它们易于收集和识别，它们的定居生活史通常导致物种之间的明确界限。这项研究将有助于建立一个更好的物种分类，并帮助目录和了解地球？由于该项目涉及美国、中国、澳大利亚、新西兰、斯洛文尼亚、法国、荷兰和南非的研究人员，它将促进思想和技术以及标本的国际交流。 这项研究将解决一系列广泛的重要问题，如气候变化如何影响物种形成，以及随着时间的推移分子变化机制的信息在分子树构建中的应用。科学上的新物种肯定会被发现。 这项研究将有助于培养本科生，研究生和博士后研究人员，包括代表性不足的群体。 这项研究的结果将通过我们的网站提供，并将包括一个电子现场指南，其中包括收集的鸟类物种的分布以及许多物种的照片和歌曲。该网站还将提供世界蝉工作者的最新名单、世界蝉分类学研究的现状、与其他蝉网站的链接、三个大型网络搜索数据库（Magicicada、NZ cicadas和World Cicadas）、种类位置列表、地图、系统发育树、地点指南等。
