鉴于白天和夜间的环境条件和活跃生物区系的显著差异，生态系统的功能几乎不可避免地也会有所不同。然而，由于在夜间进行研究的挑战，对这些差异的理解受到了阻碍。与此同时，许多人为压力在白天施加得最强或影响最大（例如，高温、干扰）或夜间（例如，人工照明，夜晚比白天升温更快）。在这里，我们探讨目前的理解，昼夜（每日）变化的五个关键生态系统功能，以及在昼夜周期中，他们主要发生[捕食（不清楚），草食动物（夜间），授粉（白天），种子传播（不清楚），碳同化（白天）]和如何昼夜不对称的人为压力影响这些功能。
Given the marked differences in environmental conditions and active biota between daytime and nighttime, it is almost inevitable that ecosystem functioning will also differ. However, understanding of these differences has been hampered due to the challenges of conducting research at night. At the same time, many anthropogenic pressures are most forcefully exerted or have greatest effect during either daytime (e.g., high temperatures, disturbance) or nighttime (e.g., artificial lighting, nights warming faster than days). Here, we explore current understanding of diel (daily) variation in five key ecosystem functions and when during the diel cycle they primarily occur [predation (unclear), herbivory (nighttime), pollination (daytime), seed dispersal (unclear), carbon assimilation (daytime)] and how diel asymmetry in anthropogenic pressures impacts these functions.
