Attempts to restore damaged ecosystems reveal inadequacies in theories describing ecosystem structure and function. For rivers, it is unclear whether theories relating to fluvial geomorphology and ecosystem dynamics are adequate to predict system trajectories following restoration. We will use empirical data on a degraded river to develop cross-scale models of system function, and predict ecosystem structure and dynamics following restoration. Following revegetation of riparian habitats and replacement of large woody debris in in-stream habitats of the river, we will test theoretical predictions about changes to physical processes, biotic community assemblage rules and food webs to develop improved ecosystem-based restoration guidelines.

试图恢复受损的生态系统揭示了描述生态系统结构和功能的理论的不足。对于河流，尚不清楚与河流地貌和生态系统动力学有关的理论是否足以预测恢复后的系统轨迹。我们将使用退化河流的经验数据来建立系统功能的跨尺度模型，并预测恢复后的生态系统结构和动态。随着河岸生境的重建和河流溪流生境中大型木质碎屑的替换，我们将检验关于物理过程、生物群落组合规则和食物网变化的理论预测，以制定改进的基于生态系统的恢复指南。
