Abstract

Heat extremes have become the new norm in the Anthropocene. Their potential to trigger major ecological responses is widely acknowledged, but their unprecedented severity hinders our ability to predict the magnitude of such responses, both during and after extreme heat events. To address this challenge we propose a conceptual framework inspired by the core concepts of ecological stability and thermal biology to depict how responses of populations and communities accumulate at three response stages (exposure, resistance, and recovery). Biological mechanisms mitigating responses at a given stage incur associated costs that only become apparent at other response stages; these are known as 'ecological debts'. We outline several scenarios for how ecological responses associate with debts to better understand biodiversity changes caused by heat extremes.

极端高温引发的生态负债。
极端高温已成为人类世的新常态。它们引发重大生态响应的潜力已得到广泛认可,但其前所未有的严重性阻碍了我们预测极端热事件期间和之后的响应程度的能力。为了应对这一挑战,我们受生态稳定性和热生物学核心概念的启发,提出了一个概念框架,以描述种群和群落的响应如何在三个响应阶段(暴露、抵抗和恢复)累积。在特定阶段减轻反应的生物机制会产生相关成本,而这些成本只有在其他反应阶段才会显现出来;这些成本被称为 "生态债务"。我们概述了生态响应如何与债务相关联的几种情况,以便更好地理解极端高温引起的生物多样性变化。

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.
