珊瑚广播产卵事件——在与月亮周期相关的可预测的特定夜晚释放配子——对大规模死亡后珊瑚礁的维护和恢复至关重要。来自沿海和近海开发的夜间人造光（ALAN）掩盖了自然光，威胁着珊瑚礁的健康：与广播产卵同步的黑暗周期。利用最近出版的水下光污染地图集，我们分析了21世纪以来2135次产卵观测的全球数据集。对于大多数属来说，与未被照亮的珊瑚礁相比，暴露在光污染下的珊瑚在满月前一到三天产卵。ALAN可能通过在满月之后的夜晚，在日落和月出之间创造一个感知到的最低照度的时期，来推进产卵的触发。提前大规模产卵的时间可能会降低配子受精和存活的可能性，这对涉及珊瑚礁系统恢复力的生态过程有明显的影响。这项全球分析表明，来自城市的人造光与珊瑚同步释放卵子的破坏有关。这种情况可能会降低珊瑚的生殖健康，阻碍在气候变化和其他人为影响下的保护工作。
Coral broadcast spawning events - in which gametes are released on certain nights predictably in relation to lunar cycles - are critical to the maintenance and recovery of coral reefs following mass mortality. Artificial light at night (ALAN) from coastal and offshore developments threatens coral reef health by masking natural light:dark cycles that synchronize broadcast spawning. Using a recently published atlas of underwater light pollution, we analyze a global dataset of 2135 spawning observations from the 21st century. For the majority of genera, corals exposed to light pollution are spawning between one and three days closer to the full moon compared to those on unlit reefs. ALAN possibly advances the trigger for spawning by creating a perceived period of minimum illuminance between sunset and moonrise on nights following the full moon. Advancing the timing of mass spawning could decrease the probability of gamete fertilization and survival, with clear implications for ecological processes involved in the resilience of reef systems. This global analysis reveals that artificial light from cities is associated with the disruption of synchronised egg release by corals. This situation could reduce coral reproductive health, hindering conservation efforts in the face of climate change and other anthropogenic impacts.
