夜间人工光照会对人类和生态系统的健康产生负面影响。(1-4)海洋生物，特别是珊瑚礁，依赖阳光和月光的自然光循环来调节各种生理、生物和行为过程。(5-8)在这里，我们证明了光污染导致印度-太平洋两种珊瑚物种--千粒状顶孔珊瑚(Acropora Millepora)和毛状顶孔珊瑚(Acropora Diditifera)配子发生延迟和配子释放不同步。鉴于主要海岸的城市化，光污染可能会进一步威胁珊瑚群落的种群，而珊瑚群落已经处于严重退化之中。提供了一个全球模拟的光污染影响评估，它可以帮助将一个重要的变量纳入珊瑚礁保护规划。
Artificial light at night (ALAN) can have negative impacts on the health of humans and ecosystems.(1-4) Marine organisms, including coral reefs in particular, rely on the natural light cycles of sunlight and moonlight to regulate various physiological, biological, and behavioral processes.(5-8) Here, we demonstrate that light pollution caused delayed gametogenesis and unsynchronized gamete release in two coral species, Acropora millepora and Acropora digitifera, from the Indo-Pacific Ocean. Given the urbanization along major coasts, light pollution could thus further threaten coral communities' populations, which are already under severe degradation. A worldwide-modeled light pollution impact assessment is provided, which can help incorporate an important variable in coral reef conservation planning.
