How and why species diversify is a central question of biology and the process of speciation is how all biodiversity is created. Islands provide an excellent setting in which to study speciation in wild populations due to their discrete geography and well-characterized geologic record. The Indo-Pacific, from Southeast Asia to Polynesia, is the cradle of speciation theory and home to numerous geographic radiations of widespread, rapidly evolving species complexes. This project will synthesize genomics and state-of-the-art trait datasets to reveal processes that promote rapid radiations in nature. Specifically, it will use a widespread, species-rich genus of island kingfishers (Aves: Todiramphus) as its study system. This project aims to make broadly applicable and generalizable predictions about the speciation process. The outcomes of this project will be a model for future speciation research in the Pacific and serve as a springboard for pioneering new ways of studying complex phenotypes and their interactions with nature. This project will engage the public through virtual and face-to-face experiences. The researchers will create virtual collections experiences (VCEs) that highlight the associated natural history collections at the Museum of Southwestern Biology and The Field Museum. These online tools will reveal how data are collected from specimens and used to address the project’s research objectives. The VCEs will be developed as education modules for grades 9–12, complete with lesson plans and student learning outcomes. The researchers will development a highly multisensory exhibit at The Field Museum, playing on the project’s themes of color evolution that will reach an estimated 500,000 people in Chicago. An educational workshop will be held at the Museum of Southwestern Biology that will provide hands-on training and experience in biodiversity science to Native American and Hispanic students from UNM and New Mexico’s rural-area institutions. It will showcase professional opportunities in STEM with a focus on museum-based biodiversity science.Speciation genomics addresses the roles of ecology, gene flow, and genomic architecture in the formation of species. This project proposes an integrative study of systematics, biogeography, plumage diversification, and ecological adaptation to test multiple hypotheses of the factors that promoted rapid diversification in a diverse and widespread radiation of island kingfishers. Todiramphus kingfishers occur across the entire Indo-Pacific and their diversification rate rivals those of “classic” adaptive radiations. This study system provides replicated instances of sympatry and isolation, as well as divergent ecologies required for a synthetic study of diversification. The project will generate diverse datasets including whole genomes, ecological niche models, and phenotypic traits, to study how these factors facilitated rapid radiation on islands over the last 10 million years. The proposed research will leverage this unique geographic context to provide novel insights into the multifaceted process of speciation by (a) quantifying the presence and extent of gene flow and how novel changes in genomic architecture influenced diversification; (b) assessing how extrinsic traits (plumage coloration, biogeography, and relative niche conservatism) promoted or inhibited species divergence in the clade; and (c) through a novel test of the abundance-niche-center hypothesis in the context of genomic and phenotypic diversity.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.

如何以及为什么物种多样化是生物学的核心问题，而规范的过程是如何产生所有生物多样性。岛屿提供了一个很好的环境，可以在其中研究野生人口的规格，这是由于其离散的地理位置和特征良好的地质记录。从东南亚到波利尼西亚的印度太平洋是规范理论的摇篮，也是广泛，迅速发展的物种复合物的许多地理辐射。该项目将综合基因组学和最先进的特征数据集，以揭示促进自然界快速辐射的过程。具体而言，它将使用岛翠鸟（Aves：Todiramhus）的宽阔，物种丰富的属作为研究系统。该项目旨在对规范过程进行广泛适用且可推广的预测。该项目的结果将成为太平洋未来规格研究的模型，并成为开拓新的研究复杂表型及其与自然相互作用的新方法的跳板。该项目将通过虚拟和面对面的体验吸引公众。研究人员将创建虚拟收藏经验（VCE），以突出西南生物学博物馆和田野博物馆的相关自然历史收藏。这些在线工具将揭示如何从标本中收集数据，并用于解决项目的研究目标。 VCE将作为9 - 12年级的教育模块开发，并附有课程计划和学生学习成果。研究人员将在现场博物馆开发一个高度的多感官展览，以该项目的色彩进化主题播放，该项目将在芝加哥估计有500,000人。将在西南生物学博物馆举行一个教育研讨会，该博物馆将为美国联合国大学和新墨西哥州农村地区机构的美洲原住民和西班牙裔学生提供动手培训和经验。它将展示STEM中的专业机会，重点是基于博物馆的生物多样性科学。规范基因组学探讨了生态学，基因流和基因组建筑在物种形成中的作用。该项目提出了一项对系统学，生物地理学，羽毛多样化和生态适应性的综合研究，以检验促进岛翠鸟的多元化和宽度辐射中快速多样化的因素的多个假设。 Todiramhus翠鸟发生在整个印度太平洋及其多元化率骑士“经典”自适应辐射。该研究系统提供了复制的综合和隔离实例，以及多样化的合成研究所需的不同生态学。该项目将产生转移数据集，包括整个基因组，生态利基模型和表型特征，以研究这些因素如何促进过去一千万年的岛屿快速辐射。拟议的研究将利用这种独特的地理环境来通过（a）量化基因流的存在和程度以及基因组结构的新颖变化影响多样化的多样化； （b）评估外在性状（羽毛色，生物地理学和相对生态位保守主义）如何促进或抑制进化枝的差异； （c）通过在基因组和表型多样性背景下对抽象 - 基因中心假设的新测试。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响来评估NSF的法定任务。
