Body size reduction is a universal response to warming, but its ecological consequences across biological levels, from individuals to ecosystems, remain poorly understood. Most biological processes scale with body size, and warming-induced changes in body size can therefore have important ecological consequences. To understand these consequences, we propose a unifying, hierarchical framework for the ecological impacts of intraspecific body size reductions due to thermal plasticity that explicitly builds on three key pathways: morphological constraints, bioenergetic constraints and surface-to-volume ratio. Using this framework, we synthesize key consequences of warming-induced body size reductions at multiple levels of biological organization. We outline how this trait-based framework can improve our understanding, detection and generalization of the ecological impacts of warming.
体型减小是对变暖的普遍响应，但它在个体到生态系统等各个生物学层次上的生态后果仍知之甚少。大多数生物过程都与体型有关，因此，由热塑性引起的体型变化可能会产生重要的生态后果。为了理解这些后果，我们提出了一个统一的、层次化的框架，用于解释由于热塑性导致的种内体型减小对生态的影响，该框架明确基于三个关键途径：形态约束、生物能量约束和表面积与体积比。利用这个框架，我们综合了在多个生物学组织层次上由变暖引起的体型减小的关键后果。我们概述了这种基于特征的框架如何提高我们对变暖的生态影响的理解、检测和概括。
