Abstract

Facilitative interactions play crucial roles in community organization, and the stress gradient hypothesis (SGH) provides a simple conceptual framework for the context-dependency of competitive and facilitative interactions. The idea is that positive interactions are more common under high physical and consumer stress, where species benefit from stress-tolerant neighbors, than in benign environments. We explore insights from the SGH into ecological generality, niche theory, community assembly, and diversity effects on ecosystem function and discuss how the SGH can inform our understanding of rapid evolution, mutualisms, exotic invasions, and facilitation cascades. We suggest that, with escalating global stresses, the SGH may provide a conceptual template for an interdependent perspective in ecology that can contribute to conservation and restoration efforts.

社区中的积极互动和相互依存。
促进性相互作用在群落组织中起着至关重要的作用,压力梯度假说(SGH)为竞争性和促进性相互作用的环境依赖性提供了一个简单的概念框架。该假说的观点是,在高物理压力和高消费压力下,良性互动比在良性环境中更常见,因为在高物理压力和高消费压力下,物种能从耐压的邻居那里获益。我们探讨了 SGH 对生态一般性、生态位理论、群落组合和多样性对生态系统功能影响的见解,并讨论了 SGH 如何帮助我们理解快速进化、互惠关系、外来入侵和促进级联。我们认为,随着全球压力的不断增加,SGH 可以为生态学中的相互依存观点提供一个概念模型,从而有助于保护和恢复工作。

期刊介绍: Trends in Ecology & Evolution (TREE) is a comprehensive journal featuring polished, concise, and readable reviews, opinions, and letters in all areas of ecology and evolutionary science. Catering to researchers, lecturers, teachers, field workers, and students, it serves as a valuable source of information. The journal keeps scientists informed about new developments and ideas across the spectrum of ecology and evolutionary biology, spanning from pure to applied and molecular to global perspectives. In the face of global environmental change, Trends in Ecology & Evolution plays a crucial role in covering all significant issues concerning organisms and their environments, making it a major forum for life scientists.
