NSF Postdoctoral Fellowship in Biology FY 2012

生物和物理对生态系统代谢和养分吸收的影响破解能量和养分资源之间的相互联系以及它们如何联合收割机影响养分吸收和生态系统代谢仍然是生态科学的一个重大挑战。以前的研究集中在这些过程的静态措施和有限的信息存在这些动态的空间和时间的变化。该项目使用新的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。跨越两个不同气候、植被、地貌和生态区域的数据将允许在区域之间进行比较。该研究旨在对生态系统代谢和营养吸收的生物和物理耦合影响进行新的理解。博士后研究员将发展测量和模拟生态和水文过程的高级技能。跨大学的实地课程的开发将培养学生在新开发的方法，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溪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公开提供，与当地水质团体的互动将扩大科学界以外的影响。

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.
