项目摘要

Páramos are high-altitude tundra ecosystems nested at the heart of the Andes mountains. These cold and humid environments are home to a multitude of plants, animals, and insects. Páramos are a critical water source for downstream urban centers, including Colombia's capital city, Bogota. Additionally, the Páramos soils contain substantial organic carbon reserves due to slow rates of organic matter decomposition. Beyond being a pool of carbon sequestered away from the atmosphere, this large reservoir of organic matter controls the soils’ hydraulic and fertility properties. The Páramos’ unique geographic location, at an elevation above 2,800 m above sea level, makes them highly vulnerable to the impacts of climate change. In fact, these ecosystems’ surface areas are projected to shrink by half within the next 50 years possibly causing loss of the essential services they provide. This project aims to characterize the microbial diversity in the Páramos soils in Colombia and investigate how climate change will affect microbes’ functions. The research is of high importance, considering that immediate and long-term changes in microbial metabolism could impact the ability of Páramos soils to store organic carbon and regulate downstream water flow. To study the cascading effect of climate change on Páramos ecosystems, this project will jumpstart collaborations among transdisciplinary experts that will integrate the research of below-ground microbial communities with above-ground vegetation functions. The project will also engage high school and undergraduate students that will work together to develop and deploy low-cost long-term soil monitoring data loggers in Chingaza National Natural Park, near the city of Bogota. This project will address the critical need to disentangle the effect of moisture and temperature on the fate of organic carbon in Páramos soils while building a transdisciplinary team capable of expanding the scope of the research to an ecosystem level. The project includes establishing controlled soil mesocosms that will allow to independently vary moisture and temperature levels. Additionally, functions of the soil microbiome will be investigated using metagenomics and amplicon sequencing, and probes will be deployed to initiate long-term monitoring of the soil response to climate change in situ. This project will culminate in the organization of an international Páramos symposium that will set up priorities for future systems research. The symposium will bring together scientists from diverse fields to discuss the linkages between above-ground and below-ground ecosystem functions and plan future collaborations in predicting Páramos-wide effects of climate change.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.
Páramos是位于安第斯山脉中心的高海拔苔原生态系统。这些寒冷潮湿的环境是许多植物、动物和昆虫的家园。Páramos是下游城市中心的重要水源,包括哥伦比亚首都波哥大。此外,Páramos土壤含有大量的有机碳储量,由于缓慢的有机物分解速率。除了作为一个与大气隔绝的碳库之外,这个巨大的有机物质库还控制着土壤的水力和肥力特性。Páramos独特的地理位置,海拔2800米以上,使它们极易受到气候变化的影响。事实上,这些生态系统的表面积预计将在未来50年内缩小一半,可能导致它们提供的基本服务丧失。该项目旨在描述哥伦比亚Páramos土壤中的微生物多样性,并研究气候变化将如何影响微生物的功能。考虑到微生物代谢的即时和长期变化可能影响Páramos土壤储存有机碳和调节下游水流的能力,该研究具有很高的重要性。为了研究气候变化对Páramos生态系统的级联效应,该项目将启动跨学科专家之间的合作,将地下微生物群落的研究与地上植被功能结合起来。该项目还将吸引高中生和大学生参与,他们将共同努力,在波哥大市附近的Chingaza国家自然公园开发和部署低成本的长期土壤监测数据记录仪。该项目将解决迫切需要解开水分和温度对Páramos土壤中有机碳命运的影响,同时建立一个跨学科团队,能够将研究范围扩大到生态系统水平。该项目包括建立受控的土壤生态系统,使其能够独立地改变湿度和温度水平。此外,将利用宏基因组学和扩增子测序技术研究土壤微生物组的功能,并部署探针对土壤对气候变化的响应进行长期监测。该项目最终将组织一次国际Páramos专题讨论会,为今后的系统研究确定优先事项。研讨会将汇集来自不同领域的科学家,讨论地上和地下生态系统功能之间的联系,并规划未来在预测Páramos-wide气候变化影响方面的合作。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
