The Philippine Archipelago represents a natural model system for the study of the processes of diversification. The islands harbor one of the greatest concentrations of biodiversity in the world and have a dynamic, yet well-understood, geological history. During the last 500,000 years, sets of islands in the Philippines have been repeatedly connected and isolated by changing sea levels. The researchers will use molecular data from populations of six species (three lizards and three frogs) co-distributed across one such set of islands and novel analytical techniques to test hypotheses about how recent climate change and associated sea-level change has influenced diversification in this dynamic system.This research will yield insights into the processes responsible for the formation of new species, and investigate the effect of climate and sea-level change on biodiversity. This information is vitally important for understanding the long-term effects that current climate change will have on global biodiversity. One of the analytical techniques developed for this research will represent an important tool for delimiting species in a way that is both biologically and statistically meaningful, which will have important implications for both basic and conservation research.

菲律宾群岛是研究多样化进程的一个自然模式系统。 这些岛屿拥有世界上最大的生物多样性集中地之一，并拥有一个动态的，但很好理解的地质历史。 在过去的50万年里，菲律宾群岛不断地被海平面的变化所连接和孤立。研究人员将使用来自六个物种种群的分子数据（三只蜥蜴和三只青蛙）共同分布在这样一组岛屿和新的分析技术，以测试有关最近的气候变化和相关的海平面变化如何影响这个动态系统的多样化的假设。这项研究将产生对新物种形成过程的见解，研究气候和海平面变化对生物多样性的影响。 这些信息对于了解当前气候变化对全球生物多样性的长期影响至关重要。为这项研究开发的分析技术之一将是一个重要的工具，以生物学和统计学意义的方式界定物种，这将对基础研究和保护研究产生重要影响。
