项目摘要

Biological and physical influences on ecosystem metabolism and nutrient uptakeDeciphering the interconnections between energy and nutrient resources and how they combine to influence nutrient uptake and ecosystem metabolism remains a grand challenge in the ecological sciences. Previous research has focused on static measures of these processes and limited information exists on the spatial and temporal variability of these dynamics. This project uses new methods and sensor technologies to decipher the dynamic interconnections between energy, nutrient resources, ecosystem metabolism, and nutrient uptake. Data across two zones of differing climate, vegetation, landforms, and ecology will allow for comparisons between regions. This research seeks new understanding of the coupled biological and physical influences on ecosystem metabolism and nutrient uptake.The postdoctoral fellow will develop advanced skills in measuring and modeling ecological and hydrological processes. The development of an inter-university field-based course will train students in the newly developed methods, technologies, and data analysis techniques. Interdisciplinary interactions at the Nicholas School of the Environment and the River Center will help expand this work beyond stream studies to aquatic ecosystems. Data generated from this research will be made publicly available through the hydrologic data sharing system, CUAHSI HIS, and interaction with local water quality groups will expand the impacts beyond the scientific community.

对生态系统代谢和养分吸收的生物和物理影响破译能量和养分资源之间的相互关系以及它们如何结合起来影响养分吸收和生态系统代谢仍然是生态科学中的一个巨大挑战。先前的研究主要集中在这些过程的静态测量上，并且关于这些动态的空间和时间变化的信息有限。该项目使用新方法和传感器技术来破译能量、营养资源、生态系统代谢和营养吸收之间的动态相互关系。两个不同气候、植被、地貌和生态的区域的数据将有助于区域之间的比较。这项研究寻求对生态系统代谢和养分吸收的生物和物理耦合影响的新认识。博士后研究员将开发测量和建模生态和水文过程的高级技能。大学间实地课程的开发将培训学生新开发的方法、技术和数据分析技术。尼古拉斯环境学院和河流中心的跨学科互动将有助于将这项工作从河流研究扩展到水生生态系统。这项研究产生的数据将通过水文数据共享系统 CUAHSI HIS 公开，并且与当地水质团体的互动将扩大科学界之外的影响。
