鉴于昼夜之间非生物和生物条件的显著变化，许多物种将其身体活动专门用于白天或夜间，并且长期以来一直认为这些策略通常是相当固定和不变的。“cathemeral”一词是在1987年创造的，当时Tattersall注意到马达加斯加灵长类动物在白天和黑夜的活动。最初被认为是罕见的，cathemerality现在被认为是节肢动物，鱼类，鸟类和哺乳动物之间相当普遍的时间划分形式。在这里，我们提供了一个综合目前的理解cathemeral行为，认为它应该经常被包括在一起的昼夜和夜间战略的计划，区分和分类物种的类群根据时间生态位。这种综合是特别及时的，因为（i）动物活动模式的研究正在被新的和改进的技术所革命;（ii）很明显，cathemerality涵盖了多种多样的专性兼性形式，每种形式都有自己共同的功能特征，地理范围和进化历史;（iii）白天和夜间活动在时间生态位划分和生态系统功能中可能发挥重要但目前被忽视的作用;和（iv）cathemerality可能在物种适应人类介导的压力的能力中发挥重要作用。
Given the marked variation in abiotic and biotic conditions between day and night, many species specialise their physical activity to being diurnal or nocturnal, and it was long thought that these strategies were commonly fairly fixed and invariant. The term ‘cathemeral’, was coined in 1987, when Tattersall noted activity in a Madagascan primate during the hours of both daylight and darkness. Initially thought to be rare, cathemerality is now known to be a quite widespread form of time partitioning amongst arthropods, fish, birds, and mammals. Herein we provide a synthesis of present understanding of cathemeral behaviour, arguing that it should routinely be included alongside diurnal and nocturnal strategies in schemes that distinguish and categorise species across taxa according to temporal niche. This synthesis is particularly timely because (i) the study of animal activity patterns is being revolutionised by new and improved technologies; (ii) it is becoming apparent that cathemerality covers a diverse range of obligate to facultative forms, each with their own common sets of functional traits, geographic ranges and evolutionary history; (iii) daytime and nighttime activity likely plays an important but currently neglected role in temporal niche partitioning and ecosystem functioning; and (iv) cathemerality may have an important role in the ability of species to adapt to human‐mediated pressures.
