0531754Maddison Human beings, also it would appear, have "an inordinate fondness for beetles" (to cite J.B.S. Haldane), at least an inordinate fondness for the study of this species-rich and life-history diverse lineage of insects. A team led by Dr. Brian Farrell at Harvard University, Dr. Michael Whiting at Brigham Young University, and Dr. David Maddison at the University of Arizona, with colleagues from around the world, will conduct an extensive study of beetle (insect order Coleoptera) phylogeny to provide the first broad scale view of beetle diversification. With ca. 350,000 described species, beetles comprise a huge fraction of the world's biota and are dominant in every terrestrial ecosystem. Beetles represent the most diverse and rapid radiation of any terrestrial organismal group, yet we have only a rudimentary knowledge of their deeper level phylogeny, and still do not understand even their most basic patterns of diversity. Collectively, beetles represent nearly every feeding habit among insects including herbivory and fungivory (feeding upon fungi), saprophagy (feeding upon decaying matter), predation and parasitism, and a thorough study of their evolutionary history would provide insight into the role of feeding habits in species diversity. The team of 40 leading beetle researchers worldwide, with expertise in nearly every beetle lineage, proposes to construct a framework phylogeny (genealogical tree) for all beetles, utilizing a 3-tier approach. Tier 1: 54 exemplar species, representing all major beetle lineages, will be sampled extensively for character data (morphology plus 23kb of DNA sequence data including complete mitochondrial genomes) to provide a robust outline of the relationships among the major (superfamily) groups of beetles. Tier 2: 300 additional species will sampled for morphology and 12kb of sequence data to establish relationships among beetle families. Tier 3: 3000 additional species will be sequenced for 1.5 kb of DNA sequence data, with morphology added for a subset of these, to better characterize the grand diversity of beetle phylogeny at the subfamilial level. Novel bioinformatics tools will be developed to streamline data processing for the molecular and morphological data, and will allow for greater efficiency, accuracy, and reproducibility of the data and associated results, while providing an online framework for collaboration by participants throughout the world. This represents the first time that coleopterists have collaborated on such a large-scale phylogenetic project, and the work should result in a robust estimate of beetle phylogeny that will provide a predictive basis for classification and integration of information on this ecologically and economically important group of insects. Information on all aspects of beetles will be disseminated through the Tree-of-Life website hosted at the University of Arizona, a traveling Spanish-language / English-language museum exhibit, and through publications and symposia. This research will provide training for graduate students, undergraduates, and high school students, including 10 female researchers and an undergraduate student with disabilities.

0531754人类也将看起来“对甲壳虫的热爱”（引用J.B.S. Haldane），至少对研究这种物种富含昆虫的多种物种多样性的谱系至少对研究。由哈佛大学Brian Farrell博士，Brigham Young University的Michael Whiting博士和亚利桑那大学的David Maddison博士领导的团队，将与来自世界各地的同事一起进行广泛的研究（昆虫的胶质翅目）系统发育，以提供啤酒多样化的第一个杂乱无章的视野。与大约350,000种描述的物种，甲虫占世界生物群的很大一部分，并且在每个陆地生态系统中都占主导地位。甲虫代表了任何陆地有机体中最多样化，最快的辐射，但我们只有对它们更深层次的系统发育的基本知识，甚至仍然不了解它们最基本的多样性模式。总的来说，甲虫几乎代表了包括食草动物和真菌（以真菌为食），腐烂物（以腐烂的物质为食），捕食和寄生虫的昆虫之间的几乎所有喂养习惯，并且对它们的进化史进行了彻底的研究，可以洞悉饲料在物种多样性中的作用。全世界40个领先的甲虫研究人员组成的团队几乎在每个甲壳虫谱系中都拥有专业知识，它建议使用3层方法为所有甲虫建造一个框架系统发育（家谱树）。 1：54级示例物种，代表所有主要的甲虫谱系，将对角色数据（形态和23kb的DNA序列数据）进行广泛采样，包括完整的线粒体基因组），以提供甲壳虫基团（主要（超家族）组之间关系的鲁棒轮廓。 第2：300层将以形态学和12KB的序列数据进行采样，以在甲虫家族之间建立关系。 将对1.5 kb的DNA序列数据进行测序3：3：3000个物种，并为其中的一部分增加了形态，以更好地表征甲虫下属水平上甲虫系统发育的巨大多样性。将开发新颖的生物信息学工具来简化分子和形态数据的数据处理，并可以提高数据和相关结果的效率，准确性和可重复性，同时为全球参与者提供在线协作的在线框架。这代表了鞘翅目第一次在这样一个大规模的系统发育项目上合作，这项工作应导致甲虫系统发育的稳健估计，该估计将为对这一生态和经济重要的昆虫群体的信息分类和整合提供预测基础。 有关甲虫各个方面的信息将通过亚利桑那大学（University of Arizona）的生活树网站传播，亚利桑那大学（University of Arizona）是一家旅行的西班牙语 /英语博物馆展览，以及通过出版物和座谈会。 这项研究将为研究生，本科生和高中生提供培训，其中包括10位女性研究人员和一名本科生的残疾人。
