Systematics and biogeography of Australian Cicadettini and their relatives worldwide

这个项目的目标是对蝉的传播模式进行彻底的研究，推断它是如何随着时间的推移形成新物种和殖民新地区的。利用DNA数据建立进化树，并为分枝事件(过去的物种形成)指定日期，就可以理解这种殖民现象。结果将在过去气候变化的背景下看待。蝉是这类研究的极好模型，因为它们在世界各地都有分布，它们的求爱歌声使它们很容易被收集和识别，它们的久居生活史通常导致物种之间的清晰界限。这项研究将有助于建立更好的蝉物种分类，帮助编目和了解正在迅速消失的地球-S生物多样性。由于这个项目涉及美国、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、技术和标本的国际交流。这项研究将解决广泛的重要问题，如气候变化如何影响物种形成，以及分子随时间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，其中将包括一份电子野外指南，其中包括收集到的蝉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、世界蝉分类研究现状、其他蝉站点的链接、三个可在网上搜索的大型数据库(Magicada、新西兰蝉和世界蝉)、类型位置列表、地图、系统发育树、地点指南等。

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.
