The high elevation grassland ecosystem of the Northern Andes, known as páramo, is the most diverse ecosystem of the high elevations of the world, and is an ideal system to understand how species arise and adapt. The goal of this project is to understand the mechanisms of speciation in the páramos and to explore the impacts of climate change on the geographic distribution of species. This will be accomplished using molecular techniques combined with geographic information systems for a dramatic radiation of 140 species of frailejones (plants related to sunflowers) of the páramos, which provide a potential model system for investigating these phenomena. Results from this project will enable a better understanding of rapid speciation processes as well as possible outcomes under different scenarios of climate change. This knowledge will inform conservation and management decisions for the South American páramos and policy development by local authorities. The project will develop tools and methodologies that can be applied in other endangered habitats and species. A public website will be developed and a key to species will also be available on DVD. The project will strengthen multinational collaborations and will train undergraduates at the home institution as well as several visiting researchers.

北安第斯山脉的高海拔草原生态系统被称为Páramo，是世界上高海拔地区最多样化的生态系统，是了解物种如何产生和适应的理想系统。该项目的目标是了解PáRamos地区物种形成的机制，并探索气候变化对物种地理分布的影响。这将利用分子技术和地理信息系统相结合，对PáRamos的140种植物(与向日葵有关的植物)进行戏剧性的辐射，这为研究这些现象提供了一个潜在的模型系统。该项目的成果将使人们能够更好地了解快速物种形成过程以及在不同气候变化情景下可能产生的结果。这些知识将为南美洲PáRamos的保护和管理决策以及地方当局的政策制定提供参考。该项目将开发可应用于其他濒危栖息地和物种的工具和方法。将开发一个公共网站，还将以DVD形式提供物种检索表。该项目将加强跨国合作，并将培训本国机构的本科生以及几名访问研究人员。
