This project aims to understand the mechanisms through which predators can control ecosystem nutrient dynamics. Ecology has been dominated for decades by the top-down/bottom-up paradigm. The project will use experiments and remote sensing observations to examine the spatial structure of feedback loops between a top predator and nutrient cycles. The expected outcome is a mechanistic and scalable understanding of the spatial distribution of nutrients and push ecosystems towards alternate states. The project will provide innovative approaches to scale-up ecological data that can be used to inform the decisions of policy makers and land managers.

该项目旨在了解捕食者控制生态系统营养动态的机制。几十年来，生态学一直被自上而下/自下而上的范式所主导。该项目将利用实验和遥感观测来研究顶级捕食者与养分循环之间反馈回路的空间结构。预期的结果是对营养物质空间分布的机械和可扩展的理解，并将生态系统推向交替状态。该项目将提供创新办法，扩大生态数据的规模，为决策者和土地管理者的决策提供信息。
