Torpor is an incredibly efficient energy-saving strategy that many endothermic birds and mammals use to save energy, by lowering their metabolic rates, heart rates, and typically body temperatures. Over the last few decades, the study of daily torpor-in which torpor is used for less than 24 hours per bout-has advanced rapidly. The papers in this issue cover the ecological and evolutionary drivers of torpor, as well as some of the mechanisms governing torpor use. We identified broad focus areas that need special attention: clearly defining the various parameters that indicate torpor use and identifying the genetic and neurological mechanisms regulating torpor. Recent studies on daily torpor and heterothermy, including the ones in this issue, have furthered the field immensely. We look forward to a period of immense growth in this field.
蛰伏是一种极其高效的节能策略，许多恒温鸟类和哺乳动物通过降低代谢率、心率以及通常的体温来利用这一策略保存能量。在过去几十年里，对每日蛰伏（即每次蛰伏时长少于24小时）的研究进展迅速。本期的论文涵盖了蛰伏的生态和进化驱动因素，以及一些控制蛰伏行为的机制。我们确定了需要特别关注的广泛重点领域：明确界定表明蛰伏行为的各种参数，以及确定调节蛰伏的遗传和神经机制。包括本期论文在内，最近关于每日蛰伏和异温性的研究极大地推动了该领域的发展。我们期待着这一领域的巨大发展。
