河流管理者努力利用现有的最佳科学来维持生物多样性和生态系统功能。为了实现这一目标，需要考虑不同规模的流程。元群落理论描述了来自不同群落的多个物种如何与当地规模的环境驱动因素相互作用，从而影响种群动态和群落结构。然而，这一知识体系很少被用来为河流生态系统的管理实践提供信息。在本文中，我们提出了一个概念模型，概述了当地生态位排序和分散的元社区过程如何影响管理干预的结果，并为应用这些想法和研究需求提供了一系列具体建议。在所有情况下，我们都确定了可以通过纳入对元社区动态的理解来增强传统河流管理方法的情况。一个共同的主题是制定评估站点或区域的元社区环境的指南，评估该环境如何影响期望的结果，并将这种理解纳入所使用的规划过程和方法中。为了最大限度地提高管理活动的有效性，科学家和资源管理者应该更新河流管理方法的工具箱，以反映元群落生态学的理论进展。
River managers strive to use the best available science to sustain biodiversity and ecosystem function. To achieve this goal requires consideration of processes at different scales. Metacommunity theory describes how multiple species from different communities potentially interact with local‐scale environmental drivers to influence population dynamics and community structure. However, this body of knowledge has only rarely been used to inform management practices for river ecosystems. In this article, we present a conceptual model outlining how the metacommunity processes of local niche sorting and dispersal can influence the outcomes of management interventions and provide a series of specific recommendations for applying these ideas as well as research needs. In all cases, we identify situations where traditional approaches to riverine management could be enhanced by incorporating an understanding of metacommunity dynamics. A common theme is developing guidelines for assessing the metacommunity context of a site or region, evaluating how that context may affect the desired outcome, and incorporating that understanding into the planning process and methods used. To maximize the effectiveness of management activities, scientists, and resource managers should update the toolbox of approaches to riverine management to reflect theoretical advances in metacommunity ecology.
