CAREER IMPACTS ANTHROPOGENICALLY DERIVED SUBSIDIES

项目摘要

Rivers and streams provide important services, such as drinking water, fisheries, and recreational opportunities. Yet, the integrity of rivers and streams throughout the globe is compromised by pollution from aging and obsolete wastewater infrastructure. Currently, there is limited understanding of how human waste affects stream communities and ecosystem processes. The project will integrate field observations, experiments, and modelling, to advance our understanding of how rivers and streams are affected by wastewater infrastructure, and will provide new insights into interactions between civil and environmental engineering and ecosystem science. This CAREER award will support the training and development of high school students, graduate students, and a postdoctoral researcher. Understanding the spatial and temporal variation in the factors influencing riverine structure and function is essential to predict how fresh waters will respond to continued anthropogenic change. This CAREER award will couple field observations with field- and lab-based experiments and modelling, to examine: 1) spatial and temporal variation in the quality, quantity, and relative volume of wastewater entering river systems, 2) the effects of wastewater on seasonal and annual patterns of metabolic processes flowing waters, 3) the influence of interactions between wastewater and ambient nutrient concentrations on trophic relationships and on the tissue and mineralization stoichiometry of consumers, and 4) the extent to which consumers transport wastewater-derived energy and elements to resource-limited systems within river networks. The award will integrate wastewater discharge into a spatial subsides framework to support more accurate predictions for how wastewater structures aquatic communities and alters biogeochemical processes in river networks. Moreover, the award will generate the data needed to compare seasonal and annual patterns in riverine metabolic processes in large, tropical rivers. The research will also test how flexibility in the trophic and stoichiometric traits of consumers governs the role they play in biogeochemical cycling under variable environmental conditions. Educational modules and service-learning projects in introductory environmental science and advanced ecology courses will be developed. High school students will be trained in stream ecology and provided internships with the local government and freshwater conservation organizations. Additionally, this research will have important management implications, as governments throughout the globe are challenged to fix wastewater effects on water quality, human health, and biodiversity.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.

河流和溪流提供重要的服务，例如饮用水，渔业和娱乐机会。然而，全球河流和溪流的完整性受到衰老和过时废水基础设施的污染损害。当前，人们对人类废物如何影响溪流社区和生态系统过程的了解有限。该项目将整合现场观察，实验和建模，以促进我们对河流和流如何受废水基础设施影响的理解，并将为民用与环境工程与生态系统科学之间的相互作用提供新的见解。该职业奖将支持高中生，研究生和博士后研究员的培训和发展。了解影响河流结构和功能的因素的空间和时间变化对于预测新鲜水对持续人为变化的反应至关重要。该职业奖将与基于现场和实验室的实验和建模相结合，以进行检查：1）质量，数量和相对体积的空间和时间变化进入河流系统的质量，数量和相对体积，2）废水对季节性和年度模式对代谢过程的季节性和年度模式的影响，3）互动及其互动的互动，3）且对营养物的影响，3）对营养不良者的影响，且对营养不良的影响效果。消费者的化学计量法，以及4）消费者在河网络中将废水衍生的能源和元素运输到资源有限的系统的程度。该奖项将将废水放电整合到空间补贴中，以支持对废水结构如何进行水生群落和改变河网络中生物地球化学过程的更准确的预测。此外，该奖项将生成比较大型热带河流河流代谢过程中季节性和年度模式所需的数据。该研究还将测试消费者营养和化学计量特征的灵活性如何控制它们在可变环境条件下在生物地球化学循环中所起的作用。将开发入门环境科学和高级生态学课程中的教育模块和服务学习项目。高中生将接受溪流生态学培训，并向地方政府和淡水保护组织提供实习。此外，这项研究将具有重要的管理意义，因为全球各地的政府要挑战废水对水质，人类健康和生物多样性的影响。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的智力优点和更广泛的影响审查标准来通过评估来进行评估的。
