Systematics and biogeography of Australian Cicadettini and their relatives worldwide

该项目的目标是对蝉的传播模式进行深入研究，推断蝉是如何随着时间的推移形成新物种并在新地区定居的。这种殖民化将通过DNA数据来构建进化树和分配分支事件（过去的物种形成）的日期来理解。研究结果将在过去气候变化的背景下进行。蝉是这类研究的绝佳模型，因为它们分布在世界各地，它们的求爱声使它们易于收集和识别，它们的定居生活历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蝉种分类学，并有助于分类和了解地球。生物多样性迅速消失。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，它将促进国际间的思想、技术和标本交流。这项研究将解决一系列重要问题，如气候变化如何影响物种形成，以及分子变化机制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。这项研究的结果将在我们的网站上公布，其中包括一份电子野外指南，上面有收集到的蝉的种类分布，以及许多种类的照片和歌声。该网站还将提供最新的世界蝉工作者名单、世界蝉分类研究现状、与其他蝉网站的链接、三个大型网络搜索数据库（Magicicada、新西兰蝉和世界蝉）、种类地点列表、地图、系统发育树、地方指南等。

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.
