Assessment of Marine Litter in the Coralligenous Habitat of a Marine Protected Area along the Ionian Coast of Sicily (Central Mediterranean)
AI summary Read the abstract
Researchers assessed the extent of marine litter in a coralligenous habitat within a Mediterranean Marine Protected Area, finding significant debris accumulation even in this protected zone. The findings highlight that MPA status alone is insufficient to prevent plastic pollution in sensitive benthic ecosystems.
In the Mediterranean Sea, the coralligenous is an extremely important habitat for its biodiversity and role in carbon sequestration. However, coralligenous biocenosis is sensitive to many anthropogenic impacts, among which one of the major threats is the marine litter. The aim of the present work was to evaluate the marine litter present in the coralligenous habitat of the Marine Protected Area (MPA) Isole Ciclopi (Sicily, Italy). Through the analysis of frames obtained by Remotely Operated Vehicles (ROV) videos, data on the type of marine litter, grade of organisms’ coverage, litter-organism interactions, and seabed coverage of items were gained. Through ROV surveys, a low number of marine litter items was observed and most of them were fishing gears. On the found items there was a high degree of organisms’ coverage, which suggests that probably the marine litter was abandoned or lost since a long time. Overall, it was observed that in recent years the fishing activity in the MPA has not affected the coralligenous habitat. The present study represents a baseline for future monitoring programmes, which will be useful to develop protection measures and sustainable fishing, in order to preserve the coralligenous habitat of the MPA.

Plastic litter in sediments from a marine area likely to become protected (Aeolian Archipelago's islands, Tyrrhenian sea)
AI summary Read the abstract
Researchers surveyed plastic litter in sediments near the Aeolian Islands in Italy, a marine area under consideration for protected status, finding microplastics in all samples at levels comparable to harbor environments. The findings show that even relatively pristine marine areas designated for protection are not immune to plastic pollution.
Mapping microplastic overlap between marine compartments and biodiversity in a Mediterranean marine protected area

Researchers mapped microplastic distribution across water, sediment, and biota in a Mediterranean marine protected area, revealing significant overlap between microplastic hotspots and biodiversity-rich zones, raising concerns about ecological impacts in supposedly protected habitats.
Are Marine-protected Areas Sheltered from Plastic Pollution?
AI summary Read the abstract
Researchers investigated microplastic pollution in the Tanon Strait, the largest marine protected area in the Philippines. Despite its protected status, the area showed relatively high microplastic concentrations, suggesting that MPAs alone do not shield marine environments from plastic contamination. The study calls for plastic pollution to be integrated into MPA management strategies.
Diversity Loss in Coralligenous Structuring Species Impacted by Fishing Gear and Marine Litter
AI summary Read the abstract
ROV surveys along Italian coastlines found that fishing gear and marine litter—including plastic—were damaging coralligenous habitat-forming species that support Mediterranean biodiversity. Marine litter entanglement and smothering by plastic debris is contributing to biodiversity loss in protected marine habitats.
High levels of microplastics and microrubber pollution in a remote, protected Mediterranean Cladocora caespitosa coral bed
AI summary Read the abstract
Researchers discovered high levels of microplastic and microrubber pollution in sediments surrounding a protected Cladocora caespitosa coral bed in the northwestern Mediterranean Sea. The study suggests that even protected marine areas with coral communities are not immune to plastic contamination, raising concerns about the ecological impact on these already threatened reef ecosystems.
