The goal of this project is to explore the role of natural selection on the wintering grounds of seasonal migratory birds in maintaining or opposing adaptive divergence. The project takes advantage of the wealth of information available for one of the most widely studied groups of animals. Additionally, the work will provide important information across all habitats for use in conservation of Neotropical migratory birds, over half of which are declining, by predicting the capacity of seasonal migratory animals to adapt to rapid environmental change. The project includes a 3-part plan to improve STEM education for underrepresented minority groups at the local, national, and international level: 1) Bird Camp – a multi-day educational outreach program targeting low-income schools in Fort Collins, Colorado; 2) Birds without Borders – a series of Spanish language (with English subtitles) videos that highlight the work of Latin American and female scientists developed with nature documentary film makers; and 3) Mexico Bioinformatics Workshop – an international genomic sequencing and bioinformatics workshop in collaboration with US and Mexican scientists. Theoretical models have long supported the idea that strong migratory connections across the annual cycle will promote local adaptation to wintering areas, but empirical research to support this hypothesis is unexplored. This knowledge gap resulted from technological hurdles related to the inability to track migratory movements and assess patterns of adaptive divergence across the genome. The goal of the proposed work is to take advantage of recent advances in tracking technology and genomic sequencing to test theoretical predictions regarding the role of previously unexplored events on the wintering grounds in the process of adaptive evolution. The proposed work will leverage and synthesize population genomic and migratory movement data for 11 species of migratory birds to provide the first empirical test of the hypothesis that strong migratory connections across the annual cycle promote local adaptation to wintering areas. Genetic estimates of gene flow across time and space will be combined with habitat modeling to answer basic questions about the role of ecology and phenology in the process of adaptive divergence in seasonal migratory birds. The integration of ecological, molecular, and statistical approaches across a range of species will allow fundamental evolutionary questions to be addressed.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.

该项目的目的是探索自然选择在季节性迁徙鸟类维持或反对自适应差异方面的作用。该项目利用了研究最广泛的动物群体之一可用的信息。此外，这项工作将通过预测季节性迁徙动物适应快速环境变化的能力来提供全部栖息地的重要信息，以保存新热带候鸟。该项目包括一个分为三部分的计划，以改善当地，国家和国际层面代表性不足的少数群体的STEM教育：1）鸟类营 - 针对科罗拉多州柯林斯堡的低收入学校的多日教育外展计划； 2）无国界的鸟类 - 一系列西班牙语（带英文字幕）的视频，这些视频突出了拉丁美洲和女科学家的作品，并用自然纪录片制作人开发； 3）墨西哥生物信息学研讨会 - 与美国和墨西哥科学家合作的国际基因组测序和生物信息学研讨会。长期以来，理论模型支持这样的想法，即在整个周期中的牢固的迁移联系将促进局部适应越冬地区，但是支持这一假设的经验研究是出乎意料的。该知识差距是由于无法跟踪整个基因组自适应差异的迁移运动和评估模式的技术障碍所产生的。拟议工作的目的是利用跟踪技术和基因组测序的最新进展，以测试有关以前意外事件在自适应演化过程中先前意外事件在越冬中的作用的理论预测。拟议的工作将利用和综合11种候鸟物种的种群基因组和迁移运动数据，以提供首次经验检验，即在整个周期中有牢固的迁移联系促进局部适应越冬地区的假设。跨时间和空间的基因流量的遗传估计将与栖息地建模相结合，以回答有关生态和物候学在季节性迁移鸟类自适应差异过程中的作用的基本问题。跨多种物种的生态，分子和统计方法的整合将允许解决基本的进化问题。该奖项反映了NSF的法定任务，并通过使用基金会的智力优点和更广泛的影响审查标准来评估，被视为通过评估而被视为宝贵的支持。
