行为和生理的昼夜节律对动物的健康和生存非常重要。在实验室中对单独隔离的动物进行的研究一直强调光在将昼夜节律夹带到相关环境周期中的主导作用。虽然在自然界中与同种的相互作用在功能上是重要的，但社会信号通常不被认为是动物昼夜节律钟的重要时间给予者。我们的研究结果挑战了这一观点。通过在生态相关的背景下研究蜜蜂并使用大量数据集，我们证明了社交诱导可能是有效的，可能在不与其他个体直接接触的情况下发挥作用，并且不依赖于控制光照。我们第一次表明，社会时间线索稳定夹带时钟，即使在动物经历冲突的光和社会环境周期。这些发现增加了对在生态相关背景下研究昼夜节律的重要性的认识。
Circadian rhythms in behaviour and physiology are important for animal health and survival. Studies with individually isolated animals in the laboratory have consistently emphasized the dominant role of light for the entrainment of circadian rhythms to relevant environmental cycles. Although in nature interactions with conspecifics are functionally significant, social signals are typically not considered important time-givers for the animal circadian clock. Our results challenge this view. By studying honeybees in an ecologically relevant context and using a massive data set, we demonstrate that social entrainment can be potent, may act without direct contact with other individuals and does not rely on gating the exposure to light. We show for the first time that social time cues stably entrain the clock, even in animals experiencing conflicting photic and social environmental cycles. These findings add to the growing appreciation for the importance of studying circadian rhythms in ecologically relevant contexts.
