I propose a conceptual shift in the way thermal physiology of reptiles is interpreted, questioning the predominant role of behaviour in reptilian thermoregulation. I will test the hypothesis that changes in cellular biochemistry are an important mechanism by which reptiles respond to environmental fluctuations. I will determine the relationship between metabolic enzyme activity and performance functions, and the results may call for a re-assessment of current concepts such as the notion that reptiles must achieve "preferred" body temperatures to maintain performance.

我提出了一个概念转变的方式解释爬行动物的热生理，质疑爬行动物的体温调节行为的主导作用。 我将检验这样一个假设，即细胞生物化学的变化是爬行动物对环境波动作出反应的一个重要机制。 我将确定代谢酶活性和性能功能之间的关系，其结果可能需要重新评估当前的概念，如爬行动物必须达到“首选”体温以保持性能的概念。
