COLLABORATIVE RESEARCH: Historical Inference in the Emberizinae (Aves: Passeriformes) Using a Complete Species-Level Phylogeny

明尼苏达大学的Scott Lanyon博士和Keith Barker博士、圣地亚哥州立大学的Kevin Burns博士、内华达大学拉斯维加斯分校的John Klicka博士和康奈尔大学的Irby Lovette博士获得了一笔资金，用于检测800多种鸟类的DNA序列。这些物种（包括黑鹂、经理人、莺和麻雀）是世界上研究得最好的鸟类之一，但这一群体的进化关系仍然存在争议，甚至在某些情况下完全未知。研究人员将检查这个多样化群体中几乎所有824个物种的DNA序列数据，这些物种代表了近十分之一的现代鸟类物种。对生命之树的研究将为今后研究西半球鸣禽的形态、行为和分布提供必要的信息。我们对鸟类多样性起源的认识的增加对西半球生物多样性的一般研究也很重要。这种鸟类在生态和经济上都很重要，了解这种鸟类的历史将刺激并为未来的研究和管理提供信息。这一组包括从重要的作物害虫到极度濒危物种的所有物种。此外，从后院喂食爱好者到认真的观鸟者，这些鸟类代表了每个人都喜欢的多样性的很大一部分。观鸟是美国增长最快的休闲活动之一，每年有7040万参与者，相关支出超过140亿美元。这个项目的重点是美国许多最常见和最容易观察到的鸟类，它代表了一个理想的机会，让公众参与到关于生命之树的讨论中来。参与的机构将通过他们现有的教育项目，向整个社区传达当前研究的重要性和相关性，从而引发这样的讨论。

A grant has been awarded to Dr. Scott Lanyon and Dr. Keith Barker at the University of Minnesota, Dr. Kevin Burns at San Diego State University, Dr. John Klicka at the University of Nevada-Las Vegas, and Dr. Irby Lovette at Cornell University to examine DNA sequences from over 800 bird species. These species (including blackbirds, tanagers, warblers, and sparrows) are among the best studied birds in the world and yet evolutionary relationships within this group remain controversial or in some cases completely unknown. The investigators will examine DNA sequence data from nearly all of the 824 species in this diverse group which represents nearly one-tenth of modern bird species. The resulting piece of the tree-of-life will provide information that will be essential to future studies of the morphologies, behaviors, and distributions of western hemisphere songbirds. This increase in our knowledge of the origins of bird diversity will also be of importance to general studies of the biodiversity of the western hemisphere. Species in this group of birds are ecologically and economically important, and understanding the group's history will stimulate and inform future research and management. This group includes everything from important crop pests to critically endangered species. Furthermore, these birds represent a huge percentage of the diversity enjoyed by everyone from backyard feeder enthusiasts to serious birders. Birding is one of the fastest growing leisure-time activities in the United States with 70.4 million participants and in excess of $14 billion dollars in related expenditures annually. This project, focused as it is on many of the most common and easily observed bird species in the US, represents an ideal opportunity to engage the public in a discussion about the Tree of Life. The participating institutions will generate such discussions through their existing education programs that communicate the importance and relevance of current research to the community at large.
