Abstract
Temporary changes in feeding rhythms were observed in the snail Cerithium spp. and the sea urchin Paracentrotus lividus due to artificial light at night (ALAN).
- Cerithium spp. and Paracentrotus lividus exhibited altered feeding rhythms when exposed to artificial light at night.
- No lasting effects of ALAN on food consumption rates were detected in the examined marine grazers.
- The intensity of the impact from ALAN decreased when exposure occurred only during part of the night.
- These findings suggest that limiting nighttime lighting could help mitigate ecological effects on coastal marine life.
