An intense concentration of biodiversity, combined with complex yet well-understood geologic and climatic histories, make the Philippines an ideal system for phylogeographic studies. This research will evaluate the relative effects of Pleistocene climate changes, geological history, and complex topography on the process of diversification in a suite of island bird species. The project integrates diverse sources of data, including mitochondrial and nuclear DNA sequences, earth history data, spatial modeling, ongoing field research, and study of museum collections. The results of this study will broadly apply to questions of how periodic climate-associated sea level changes influenced diversification and the geographic distributions of organisms in island systems.The Philippines is considered a "megadiverse country" and a "global conservation hotspot", yet traditional recognition of bird species has greatly underestimated diversity and obscured biogeographic patterns. Gene flow estimates from this study will provide an interesting new perspective on species limits across an island archipelago, and will likely elucidate novel evolutionary patterns and highlight under-appreciated centers of avian endemism in the Philippines. The project will also provide opportunities for undergraduates at the University of Kansas to gain experience in biodiversity research techniques, including DNA sequencing and analysis, and to develop research skills such as scientific writing and public presentation.

高度集中的生物多样性，再加上复杂而又易于理解的地质和气候历史，使菲律宾成为地理学研究的理想系统。这项研究将评估更新世气候变化、地质历史和复杂地形对一套岛屿鸟类物种多样化过程的相对影响。该项目整合了多种数据来源，包括线粒体和核DNA序列、地球历史数据、空间建模、正在进行的实地研究和博物馆藏品研究。这项研究的结果将广泛适用于问题的周期性气候相关的海平面变化如何影响多样化和生物的地理分布在岛屿system.The菲律宾被认为是一个“megadiversity国家”和“全球保护热点”，但传统的认识鸟类物种大大低估了多样性和模糊的地理模式。这项研究的基因流估计将为整个岛屿群岛的物种限制提供一个有趣的新视角，并可能阐明新的进化模式，并突出菲律宾鸟类特有性的未被充分认识的中心。该项目还将为堪萨斯大学的本科生提供机会，以获得生物多样性研究技术方面的经验，包括DNA测序和分析，并发展科学写作和公开演讲等研究技能。
