This study explores how light quality and nutrient availability affect the colouration, composition and physiology of Chondracanthus teedei var. lusitanicus , a red alga with potential applications in the food industry and European aquaculture. Seaweeds were exposed to four different light qualities (blue, green, amber, and red) and two nutrient conditions (nitrogen and phosphate (NP) enrichment, and phosphate (P) enrichment)....

Plastic litter in the ocean has gained significant attention over recent decades, with much of the focus on microplastics. However, macroplastic litter is prevalent in marine environments, and while its effects on single organisms is well documented, its effects on community-level biological structures remain poorly understood. This study investigates the impact of macroplastic litter—specifically polyethylene film (shopping b...
