最近记录的人为气候变化的相关性涉及到体型、模式的性质和规模的减少，这导致了对气候变暖的第三种普遍反应的建议。因为体型会影响体温调节和能量学，所以改变体型会影响面对气候变化时的适应能力。对最近研究的回顾表明，大小反应的大小和方向存在异质性，这表明有必要对时间大小变化进行大规模的系统发育控制的比较分析。对博物馆数据的综合分析，结合依赖于大小的温度调节和代谢反应的新理论模型，将增加对大小变化的潜在机制和生理后果的理解，从而提高预测物种对气候变化敏感性的能力。
A recently documented correlate of anthropogenic climate change involves reductions in body size, the nature and scale of the pattern leading to suggestions of a third universal response to climate warming. Because body size affects thermoregulation and energetics, changing body size has implications for resilience in the face of climate change. A review of recent studies shows heterogeneity in the magnitude and direction of size responses, exposing a need for large-scale phylogenetically controlled comparative analyses of temporal size change. Integrative analyses of museum data combined with new theoretical models of size-dependent thermoregulatory and metabolic responses will increase both understanding of the underlying mechanisms and physiological consequences of size shifts and, therefore, the ability to predict the sensitivities of species to climate change.
