This project addresses a fundamental research question regarding how geological processes drive the diversification of species and current patterns of biodiversity. The project will focus on western Melanesia, one of the most biodiverse regions on Earth as well as a region of high tectonic activity. A synthesis of biological and geological models for several animal groups will clarify the timing and extent of colonization and diversification of biotic diversity within the context of the region’s geologic history. The results will advance our understanding of the effects of tectonic movements on the generation and dispersal of species. The research is funded in partnership with the UK’s Natural Environment Research Council (NERC) as an international collaboration between U.S. and U.K. laboratories. The project will support the training of graduate and postdoctoral scholars, as well as collaborative training and outreach activities in Papua Guinea. The research team will construct dated phylogenetic trees for over 25 reptile and amphibian lineages representing different dispersal abilities, times of origin, and natural histories that span the five major landmasses of western Melanesia. Areas and times of origin for each group will be identified and traced to explain details of their expansion to new regions. Updated geological models will be created and will illuminate tectonic events that drove speciation and dispersal in the region. This research will test competing models for the origins and maintenance of Pacific biodiversity distributions. The results will be broadly useful as a model for investigating biogeographic evolution in regions with complex tectonic histories and dynamics.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.

该项目解决了一个基本的研究问题，即地质过程如何驱动物种的多样化和目前的生物多样性模式。该项目将侧重于西美拉尼西亚，这是地球上生物多样性最丰富的地区之一，也是构造活动最活跃的地区。综合几个动物群体的生物和地质模型，将澄清该区域地质历史背景下生物多样性的殖民化和多样化的时间和程度。研究结果将有助于我们进一步了解构造运动对物种产生和扩散的影响。这项研究是与英国自然环境研究理事会（NERC）合作资助的，是美国和英国之间的国际合作。laboratories.该项目将支持培训研究生和博士后学者，以及在巴布亚几内亚开展合作培训和外联活动。该研究小组将为超过25种爬行动物和两栖动物谱系构建过时的系统发育树，这些谱系代表了横跨西美拉尼西亚五大大陆的不同传播能力，起源时间和自然历史。将确定和追踪每个群体的起源地区和时间，以解释他们向新地区扩展的细节。将创建更新的地质模型，并将阐明驱动该地区物种形成和扩散的构造事件。这项研究将测试太平洋生物多样性分布的起源和维持的竞争模型。该成果将作为一个模型，在复杂的构造历史和dynamics.This奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持地区调查地形演变广泛有用。
