项目摘要

Coastal marshes provide a suite of vital functions that support natural and human communities. Humans frequently take for granted and exploit these ecosystem services without fully understanding the ecological feedbacks, linkages, and interdependencies of these processes to the wider ecosystem. As demands on coastal ecosystem services have risen, marshes have experienced substantial loss due to direct and indirect impacts from human activity. The rapidly changing coastal ecosystems of Louisiana provide a natural experiment for understanding how coastal change alters ecosystem function. This project is developing new metrics and tools to assess food web variability and test hypotheses on biodiversity and ecosystem function in coastal Louisiana. The research is determining how changing habitat configuration alters the distribution of energy across the seascape in a multitrophic system. This work is engaging students from the University of Louisiana Lafayette and Dillard University in placed-based learning by immersing them in the research and local restoration efforts to address land loss and preserve critical ecosystem services. Students are developing a deeper understanding of the complex issues facing coastal regions through formal course work, directed field work, and outreach. Students are interacting with stakeholders and managers who are currently battling coastal change. Their directed research projects are documenting changes in coastal habitat and coupling this knowledge with the consequences to ecosystems and the people who depend on them. By participating in the project students are emerging with knowledge and training that is making them into informed citizens and capable stewards of the future of our coastal ecosystems, while also preparing them for careers in STEM. The project is supporting two graduate students and a post-doc.The transformation and movement of energy through a food web are key links between biodiversity and ecosystem function. A major hurdle to testing biodiversity ecosystem function theory is a limited ability to assess food web variability in space and time. This research is quantifying changing seascape structure, species diversity, and food web structure to better understand the relationship between biodiversity and energy flow through ecosystems. The project uses cutting edge tools and metrics to test hypotheses on how the distribution, abundance, and diversity of key species are altered by ecosystem change and how this affects function. The hypotheses driving the research are: 1) habitat is a more important indirect driver of trophic structure than a direct change to primary trophic pathways; and 2) horizontal and vertical diversity increases with habitat resource index. Stable isotope analysis is characterizing energy flow through the food web. Changes in horizontal and vertical diversity in a multitrophic system are being quantified using aerial surveys and field sampling. To assess the spatial and temporal change in food web resources, the project is combining results from stable isotope analysis and drone-based remote sensing technology to generate consumer specific energetic seascape maps (E-scapes) and trophic niche metrics. In combination these new metrics are providing insight into species’ responses to changing food web function across the seascape and through time.This project is jointly funded by Biological Oceanography and the Established Program to Stimulate Competitive Research (EPSCoR).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.
沿海沼泽提供了一系列支持自然和人类社区的重要功能,人类经常认为这些生态系统服务是理所当然的,但没有充分了解这些过程对更广泛的生态系统的生态反馈、联系和相互依赖性。路易斯安那州快速变化的沿海生态系统为了解沿海变化如何改变生态系统功能提供了一个自然实验,该项目正在开发新的指标和工具来评估食物网。生物多样性的变异性和检验假设这项研究正在确定变化的栖息地配置如何改变多营养系统中整个海景的能量分布。这项工作让路易斯安那大学拉斐特分校和迪拉德大学的学生沉浸在基于地点的学习中。学生们通过正式课程、定向实地工作和外展活动,与利益相关者和管理人员进行互动,以解决土地流失和保护关键生态系统服务的研究和当地恢复工作。目前沿海变化面临挑战。定向研究项目记录了沿海栖息地的变化,并将这些知识与对生态系统和依赖生态系统的人们的影响结合起来。通过参与该项目,学生们获得了知识和培训,使他们成为知情的公民和有能力的管理者。该项目支持两名研究生和一名博士后,同时也为他们在 STEM 领域的职业生涯做好准备。通过食物网进行的能量转化和移动是生物多样性和生态系统功能之间的一个主要障碍。测试生物多样性生态系统功能理论是评估食物能力有限这项研究正在量化不断变化的海景结构、物种多样性和食物网结构,以更好地了解生物多样性和生态系统能量流之间的关系。该项目使用尖端工具和指标来测试有关分布方式的假设。关键物种的丰富度和多样性会因生态系统变化而改变,以及这对功能的影响。推动这项研究的假设是:1)栖息地是营养结构的间接驱动因素,而不是主要营养途径的直接变化;2)水平和垂直多样性随着栖息地资源的增加而增加稳定同位素分析正在利用航空调查和实地采样来量化多营养系统中水平和垂直多样性的变化,以评估食物网资源的空间和时间变化。稳定同位素分析和基于无人机的遥感技术的结果,可生成消费者特定的能量海景图(E-scapes)和营养位指标,这些新指标相结合,可以深入了解物种对整个海景和食物网功能变化的反应。该项目由生物海洋学和刺激竞争研究既定计划 (EPSCoR) 共同资助。该项目授予 NSF 的法定使命,并通过使用基金会的智力价值和更广泛的影响审查标准进行评估,被认为值得支持。
