Abstract
The density of late settlers (post-metamorphosis spats) was significantly lower in ALAN plates than in control plates for both barnacle species.
- Day/night cycles are important for coastal processes and may be altered by Artificial Light at Night (ALAN).
- Notochthamalus scabrosus and Jehlius cirratus were studied to assess the impact of ALAN on barnacle settlement rates.
- Early settlers (pre-metamorphosis cyprids) showed no change in density under ALAN conditions.
- ALAN exposure appears to negatively affect the settlement process of late settlers in both barnacle species.
