Artificial light at night (ALAN) is a growing threat to coastal habitats, and likely exacerbate the impacts of other stressors. Kelp forests are dominant habitats on temperate reefs but declining due ocean warming overgrazing. We tested independent interactive effects ALAN (dark versus ALAN) (ambient warm) grazing rates gonad index sea urchin Centrostephanus rodgersii. Within these treatments, urchins were fed either ‘fresh’ kelp or ‘treated’ kelp. Treated ( Ecklonia radiata ) was exposed same temperature combinations as urchins. assessed photosynthetic yield, carbon nitrogen content C : N ratio treated help identify potential drivers behind any Grazing increased with for fresh kelp, Gonad higher in ALAN/ambient dark/warm treatments compared dark/ambient than ALAN/warm one time point. This indicates may increase pressure rocky reefs, an important finding management strategies.
