Despite advances in conceptual understanding, single-stressor abatement approaches remain common in the management of fresh waters, even though they can produce unexpected ecological responses when multiple stressors interact. Here we identify limitations restricting the development of multiple-stressor management strategies and address these, bridging theory and practice, within a novel empirical framework. Those critical limitations include that (i) monitoring schemes fall short of accounting for theory on relationships between multiple-stressor interactions and ecological responses, (ii) current empirical modelling approaches neglect the prevalence and intensity of multiple-stressor interactions, and (iii) mechanisms of stressor interactions are often poorly understood. We offer practical recommendations for the use of empirical models and experiments to predict the effects of freshwater degradation in response to changes in multiple stressors, demonstrating this approach in a case study. Drawing on our framework, we offer practical recommendations to support the development of effective management strategies in three general multiple-stressor scenarios.

造浪。桥接淡水生态系统中多重压力源管理的理论和实践
尽管在概念上有了进步,但单压力消除方法在淡水管理中仍然很普遍,即使当多个压力相互作用时它们也能产生意想不到的生态响应。在这里,我们确定了限制多重压力管理策略发展的局限性,并在新颖的经验框架内解决了这些问题,在理论和实践之间架起了桥梁。这些关键的局限性包括:(i)监测方案无法解释多应力因素相互作用与生态响应之间关系的理论;(ii)当前的经验建模方法忽略了多应力因素相互作用的普遍性和强度,以及(iii)机制应激物相互作用的概念通常知之甚少。我们提供了使用经验模型和实验来预测淡水降解对多种压力源变化的响应的实用建议,并在案例研究中证明了这种方法。根据我们的框架,我们提供了实用的建议,以支持在三种通用的多压力方案中开发有效的管理策略。
