Artificial light at night at environmental intensities disrupts daily rhythm of the oyster Crassostrea gigas
Artificial Light At Night (ALAN) masks the natural light cycles and thus can disturb the synchronization of organisms' biological rhythms with their environment. Although coastlines are highly exposed to this growing threat, studies concerning the impacts of ALAN on coastal organisms remain sca...
