Artificial Light at Night (ALAN) is a common environmental pollutant which affects >22 % of the world's coastlines. However, the impact of ALAN wavelengths on coastal organisms is under-investigated. Here, we tested the impact of red, green, and white ALAN on the gaping activity and phytoplankton consumption of Mytilus edulis mussels and compared these to dark night. Mussels exhibited a semi-diel activity pattern. Although ALAN did not significantly affect the time open nor the phytoplankton consumption, it did have a colour-specific effect on the gaping frequency with red and white ALAN resulting in lower activity compared to the dark night. Green ALAN caused higher gaping frequency and a negative relationship between consumption and proportion of time open compared to the other treatments. Our findings suggest colour-specific ALAN effects on mussels and call for further investigation on the associated physiological mechanisms and potential ecological consequences.
人造光污染（ALAN）是一种常见的环境污染物，影响了全球 22%以上的海岸线。然而，ALAN 波长对沿海生物的影响还没有得到充分的研究。在这里，我们测试了红、绿、白三种 ALAN 对贻贝（Mytilus edulis）张开活动和浮游植物消耗的影响，并将其与夜间黑暗进行了比较。贻贝表现出半昼夜活动模式。虽然 ALAN 对开口时间或浮游植物消耗没有显著影响，但它确实对张开频率有特定的颜色影响，与夜间黑暗相比，红、白 ALAN 导致的活动减少。与其他处理相比，绿光 ALAN 导致更高的张开频率和消耗与开口时间比例之间的负相关关系。我们的研究结果表明，ALAN 对贻贝有特定颜色的影响，并呼吁进一步研究相关的生理机制和潜在的生态后果。
