Abstract

Foundation species facilitate communities, modulate energy flow, and define ecosystems, but their ecological roles after death are frequently overlooked. Here, we reveal the widespread importance of their dead structures as unique, interacting components of ecosystems that are vulnerable to global change. Key metabolic activity, mobility, and morphology traits of foundation species either change or persist after death with important consequences for ecosystem functions, biodiversity, and subsidy dynamics. Dead foundation species frequently mediate ecosystem stability, resilience, and transitions, often through feedbacks, and harnessing their structural and trophic roles can improve restoration outcomes. Enhanced recognition of dead foundation species and their incorporation into habitat monitoring, ecological theory, and ecosystem forecasting can help solve the escalating conservation challenges of the Anthropocene.

死亡的基础物种驱动着生态系统的动态。
基础物种促进群落,调节能量流动,定义生态系统,但它们在死亡后的生态作用经常被忽视。在这里,我们揭示了它们的死亡结构作为易受全球变化影响的生态系统的独特、相互作用的组成部分的广泛重要性。基础物种的关键代谢活动、移动性和形态特征在死亡后发生变化或持续存在,对生态系统功能、生物多样性和补贴动态产生重要影响。死亡的基础物种经常通过反馈调节生态系统的稳定性、恢复力和过渡,利用它们的结构和营养作用可以改善恢复结果。加强对死基物种的认识,并将其纳入栖息地监测、生态理论和生态系统预测,有助于解决人类世不断升级的保护挑战。

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.
