Accelerating rates of climate change have intensified research on thermal adaptation. Increasing temperature fluctuations, a prominent feature of climate change, means that the persistence of many species depends on both heat and cold tolerance across the entire life cycle. In endotherms, research has focused on specific life stages, with changes in thermoregulation across life rarely being examined. Consequently, there is a need to (i) analyse how heat and cold tolerance mechanisms coevolve, and (ii) test whether antagonistic effects between heat and cold tolerance across different life stages limit thermal adaptation. Information on genes influencing heat and cold tolerance and how they are expressed through life will enable more accurate modelling of species vulnerabilities to future climatic volatility.
气候变化的加速促使人们加强了对热适应的研究。温度波动的增加是气候变化的一个显著特征，这意味着许多物种的生存取决于整个生命周期内对热和冷的耐受性。在恒温动物中，研究主要集中在特定的生命阶段，很少研究生命过程中体温调节的变化。因此，有必要：（i）分析热和冷耐受性机制如何共同进化；（ii）检验不同生命阶段之间热和冷耐受性的拮抗作用是否限制了热适应。关于影响热和冷耐受性的基因以及它们如何在整个生命周期中表达的信息，将使对物种未来对气候波动脆弱性的更准确建模成为可能。
