The proximate currency that best explains the behaviour by animals in general and endotherms in particular, is energy. Research has focused on energy acquisition whereas my ongoing focus is to determine how, when and why endotherms (birds and mammals) employ heterothermy (e.g., torpor). For endotherms, defending a constant elevated body temperature confers fundamental physiological advantages. However the benefits must be balanced against high energetic costs, which come with elevated metabolic rates. These high costs can be offset by periods of torpor which results in reduced metabolic rates and as a consequence energetic savings.

最能解释一般动物，特别是恒温动物行为的最接近的货币是能量。 研究的重点是能量获取，而我正在进行的重点是确定如何，何时以及为什么恒温动物（鸟类和哺乳动物）采用异温（例如，迟钝）。 对于恒温动物来说，保护持续升高的体温具有基本的生理优势。 然而，这些好处必须与高能量成本相平衡，高能量成本伴随着代谢率的升高。 这些高成本可以通过导致代谢率降低的休眠期来抵消，从而节省能量。
