From the Seafloor to the Surface: a Global Review of Gastropods as Bioindicators of Marine Microplastics
This global review examined evidence of microplastic ingestion by marine gastropods (sea snails) and evaluated their potential as bioindicator species for ocean microplastic pollution. Gastropods from the seafloor to the surface were found to contain microplastics, with bottom-dwelling species accumulating the highest amounts. The authors argue that gastropods are a practical and widespread tool for monitoring microplastic contamination across marine environments.
More deterministic assembly constrains the diversity of gut microbiota in freshwater snails
Researchers compared the gut microbiota assembly processes of invasive and native freshwater snails coexisting at multiple sites in southern China.
