Energy is the currency by which the costs and benefits of many biological functions are measured and likely best explains behaviour by animals in general and endotherms in particular. My research program is focused on determining the ecological context for how, when and why endotherms use “heterothermy” to save energy. Daily torpor stems from reduced metabolism and thus reduced body temperature (Tb) leading to energetic savings. Its importance is underscored by the rapidly increasing number of species recorded to use it and the idea that it makes endotherms less susceptible to extinction.

能量是衡量许多生物功能的成本和效益的货币，可能最能解释一般动物和恒温动物的行为。我的研究项目集中在确定生态环境如何，何时以及为什么恒温动物使用“异温”来节省能源。日常的麻木源于新陈代谢的减少，从而降低了体温（Tb），导致能量的节省。它的重要性是强调了迅速增加的物种记录使用它，并认为它使恒温动物不易灭绝的想法。
