Complex system dynamics: restoring riparian and riverine ecosystems

恢复受损生态系统的努力揭示了描述生态系统结构和功能的理论的不足之处。对于河流，目前还不清楚有关河流地貌学和生态系统动力学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开发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。在对河岸栖息地进行植被重建并更换河流溪流栖息地中的大型木质残体之后，我们将测试有关物理过程、生物群落聚集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。

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.
