Determining the boundaries between species is critical for answering basic questions in biodiversity science and in the application of conservation legislation and wildlife management plans. Genomics has influenced every field in biology and the study of biodiversity is no exception; however, meaningful training in genomic techniques is unevenly distributed. This Mid-Career Award supports training in genomic tools in the study of species boundaries and speciation for faculty and students at Marshall University in West Virginia, through a unique training partnership with Ohio State University. This project leverages an international collaboration to study systematics, biogeography, and speciation in three groups of songbirds on the islands of Japan, Taiwan, and the Philippines. Because islands cover only 7% of the earth but harbor 20% of the planet’s biodiversity, studying island species in order to understand adaptive radiations is especially important. This research will cultivate new knowledge of the island birds of East Asia and foster better tools for understanding species boundaries and speciation. The work will also enable training and research opportunities in cutting-edge genomic methodologies and analyses, applicable across the life sciences, to faculty and students at a primarily undergraduate university in Appalachia. The goal of the Mid-Career Advancement (MCA) program is to enhance the research careers of mid-career scientists. The application of genomics in systematics and evolutionary biology has revolutionized these fields; however, faculty at many smaller institutions are saddled with teaching and other obligations that limit the amount of time to devote to training in new methods. As the sophistication of the questions addressed in systematics and evolutionary biology grow, typical low-throughput sequencing techniques are no longer adequate. This MCA award partners faculty and students at Marshall University in West Virginia (EPSCoR state) with faculty at Ohio State University experienced in population genomics and molecular systematics. This partnership will enable training in the application of cutting-edge genomic tools in the study of species delimitation, speciation, population genetics, adaptive evolution, and biogeography. Specifically, this project will produce and analyze genome-scale and whole genome datasets for three codistributed avian groups in East Asia – the yellow-breasted flycatcher complex, the varied tit complex, and the Asiatic white-eyes. Genomic data applied to these groups will allow researchers to assess the reliability of different species delimitation methods, the influence of island geography on population parameters, and the impact of adaptive evolution on the genome.This project is jointly funded by the Evolutionary Processes Program, and the Established Program to Stimulate Competitive Research (EPSCoR).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

确定物种之间的界限对于回答生物多样性科学中的基本问题以及保护立法和野生动物管理计划的应用至关重要。基因组学影响了生物学的各个领域，生物多样性研究也不例外;然而，基因组技术的有意义的培训分布不均。该中期职业奖通过与俄亥俄州州立大学的独特培训合作关系，支持西弗吉尼亚州马歇尔大学教师和学生在物种边界和物种形成研究中的基因组工具培训。本计画借由国际间的合作，研究日本、台湾及菲律宾三个岛屿上鸣禽族群的系统学、地理学及物种形成。由于岛屿仅占地球的7%，但却拥有地球20%的生物多样性，因此研究岛屿物种以了解适应性辐射尤为重要。这项研究将培养东亚岛屿鸟类的新知识，并为理解物种边界和物种形成提供更好的工具。这项工作还将为阿巴拉契亚一所主要是本科生的大学的教师和学生提供适用于整个生命科学的尖端基因组方法和分析方面的培训和研究机会。中期职业发展（MCA）计划的目标是增强中期职业科学家的研究职业生涯。基因组学在系统学和进化生物学中的应用彻底改变了这些领域;然而，许多较小机构的教师承担着教学和其他义务，限制了用于新方法培训的时间。随着系统学和进化生物学中所解决问题的复杂性的增长，典型的低通量测序技术不再适用。这个MCA奖合作伙伴的教师和学生在马歇尔大学在西弗吉尼亚州（EPSCoR州）与教师在俄亥俄州州立大学在人口基因组学和分子系统学经验。这一伙伴关系将使培训的尖端基因组工具的应用在物种界定，物种形成，种群遗传学，适应性进化和生物地理学的研究。具体而言，该项目将产生和分析东亚三个共同分布的鸟类群体的基因组规模和全基因组数据集-黄胸霸鹟复合体，各种山雀复合体和亚洲白眼。应用于这些群体的基因组数据将使研究人员能够评估不同物种划界方法的可靠性、岛屿地理对种群参数的影响以及适应性进化对基因组的影响，这一项目由进化过程计划联合资助，以及刺激竞争研究的既定计划（EPSCoR）该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
