AI Article Synopsis
- Microplastic ingestion was highest in sediment-feeding holothurians (12.67 MPs per individual) compared to bivalves (4.83 MPs) and fish (3 MPs), indicating a significant variation in microplastic exposure based on feeding habits.
- The predominant ingested microplastics were polyethylene, polypropylene, and polystyrene, with varying levels of hazardous plasticizers like BPA, BPS, and DEHP found across different species.
- Bivalves showed the highest concentration of BPS, BPF, and DEHP in their soft tissue, while holothurians accumulated higher levels of BPA and DBP in their muscle, highlighting the ecological impact of plastic pollution in the Cabrera Marine Protected Area.
Article Abstract
Microplastic (MP) ingestion, along with accumulated plasticizers such as bisphenol A (BPA), bisphenol F (BPF), and bisphenol S (BPS), and phthalates represented by diethyl phthalate (DEP), dibutyl phthalate (DBP) and bis (2-ethylhexyl) phthalate (DEHP), were quantified in bivalves, fish, and holothurians collected from a coastal pristine area at the western Mediterranean Sea. MP ingestion in sediment-feeders holothurians (mean value 12.67 ± 7.31 MPs/individual) was statistically higher than ingestion in bivalves and fish (mean 4.83 ± 5.35 and 3 ± 4.44 MPs/individual, respectively). The main ingested polymers were polyethylene, polypropylene, and polystyrene. The levels of BPS, BPF, and DEHP were highest in bivalves' soft tissue; BPA and DBP had the highest levels in the holothurians' muscle. In addition, the levels of all plasticizers assessed were lowest in fish muscle; only BPA levels in fish were higher than in bivalves, with intermediate values between those of bivalves and holothurians. This study provides data on exposure to MPs and plasticizers of different species inhabiting Cabrera Marine Protected Area (MPA) and highlights the differences in MP ingestion and levels of plasticizers between species with different ecological characteristics and feeding strategies.

N-methyladenosine (m6A) modification is a prevalent mRNA modification that regulates diverse biological processes in eukaryotes, including immune responses. While the role of m6A in mammalian immunity has been explored, its involvement in the immune defense of invertebrates, particularly marine bivalves which face constant pathogen challenges, remains largely unknown. Here, we investigated the function of methyltransferase-like 3 (METTL3), a key m6A "writer" enzyme, in the immune response of the marine bivalve Mytilus coruscus against Vibrio alginolyticus infection.

DNA integrity is crucial for organismal health, and assessing DNA damage in aquatic organisms is essential for identifying environmental threats and informing conservation efforts. Pollutants such as metals, hydrocarbons, agrochemicals, pharmaceuticals, and climate change are linked to genetic damage, oxidative stress, and mutagenesis in several species, such as elasmobranchs (sharks and rays). Most studies focus on bivalves, crustaceans, and bony fish, with fewer assessments being carried out in cartilaginous fish.

Article Synopsis
- Freshwater mussels, particularly those from the order Unionoida, are facing significant decline in North America, and disease pathology is an area needing more research.
- The study focused on a prevalent shell deformity found in northeastern mussel populations, specifically examining the eastern elliptio species in Massachusetts, where over 50% showed deformities.
- Results indicated that the deformity could stem from repeated growth disturbances in the shell's posterior region, leading deformed mussels to be shorter and older than their normal counterparts.
