Summary: This study investigated the differential physiological responses of male and female Manila clams to ocean acidification. The results showed that female clams had significantly depressed enzyme activities related to energy metabolism, antioxidant defense, and immune function compared to male clams under ocean acidification stress. Sex-based differences in response to ocean acidification exist in marine bivalves, likely due to the energetically expensive cost of egg production.

Summary: Untargeted Nuclear Magnetic Resonance metabolomics was used to study the effects of warming and exposure to EE2 on the metabolome of Ruditapes philippinarum clams. The results identified metabolic markers for monitoring and predicting deviant environmental conditions. Warming alone triggered changes in various metabolic pathways, while EE2 exposure caused significant metabolic disturbances. These findings help understand clams' response to temperature rise and EE2 exposure and can guide future prediction of environmental damaging effects.

Summary: The presence of pharmaceuticals in the aquatic environment is a concern, but the effects of these substances under different climate change scenarios are not well understood. This study examined the toxicological impacts of a specific pharmaceutical, 17 alpha-ethinylestradiol (EE2), on edible clams under current and predicted warming scenarios. The results showed that EE2 concentrations disturbed the redox homeostasis of the clams, but the clams were able to activate their defense mechanisms to cope with the stress.

Summary: Geographical traceability of marine bivalves is essential for ensuring quality and protecting the interests of consumers and producers. This study demonstrates the potential of using neodymium isotopic ratios as a tracer for the geographic origin of Ruditapes philippinarum shells. The Nd-143/Nd-144 ratios of clam shells from Japanese and Chinese coastal areas show a heterogeneous pattern, reflecting the geological age of the catchment area. The findings highlight the importance of using Nd-143/Nd-144 as a powerful tool in exposing fraud labeling and ensuring the authenticity of marine bivalves.

Summary: Studies have shown the presence of nanoparticles, particularly carbon nanotubes, in aquatic ecosystems, raising concerns about their toxicity when combined with other pollutants. This study evaluated the effects of carboxylated multi-walled carbon nanotubes and chromium on the metabolic capacity, oxidative status, and neurologic status of two filter feeder organisms: Ruditapes decussatus and R. philippinarum. Results revealed species-specific accumulation of chromium, with higher values in R. decussatus. Only R. philippinarum showed inhibition of antioxidant defenses and neurotoxic effects. The interaction between contaminants did not affect antioxidant enzyme activities and neuro status. However, the combined exposure to both contaminants altered the metabolic capacity of R. decussatus. Both clams were tolerant to the contaminants but showed a significant accumulation capacity, posing a potential transfer of contaminants to humans.

Summary: Nanoplastics are widely present in marine environments, with accumulation in bivalves having detrimental effects on the ecosystem. This study determined the accumulation of palladium-doped polystyrene nanoplastics in Ruditapes philippinarum and investigated its toxic effects using physiological damage assessments, a toxicokinetic model, and 16S rRNA sequencing. Significant nanoplastic accumulation was observed, leading to oxidative stress, apoptosis, and pathological damage. The study also found alterations in the intestinal microbial community structure. Overall, this work enhances our understanding of the toxic effects and environmental risks associated with nanoplastic accumulation.

Summary: This study investigates the effects of exposure to 17-α-ethinylestradiol (EE2) on lipophilic extracts of Ruditapes philippinarum clams at 17 degrees C and 21 degrees C. The results show that EE2 exposure at 17 degrees C leads to a slight increase in membrane rigidity at low concentrations, while at higher concentrations, lipid metabolism stabilizes. In contrast, at 21 degrees C, lipid metabolism responds to EE2 at 125 ng/L, with the antioxidant docosahexaenoic acid (DHA) helping to mitigate oxidative stress. The study also identifies new potential markers of stress mitigation, such as high levels of phosphatidylcholine (PtdCho), polyunsaturated fatty acids (PUFAs), and linoleic acid, as well as low PUFA/glycine ratios.

Summary: GnRH plays a crucial role in reproductive endocrine regulation in molluscs. Suppression of GnRH resulted in enriched KEGG pathways, including oxidative phosphorylation, dorso-ventral axis formation, thyroid hormone synthesis, and oxytocin signaling pathway. Genes related to steroid hormone synthesis and gonadal development were differentially expressed in both ovaries and testes with GnRH suppression. These findings suggest the importance of GnRH in reproductive function in bivalves and provide a basis for further investigating its function and regulatory mechanism.

Summary: Shellfish are increasingly seen as sustainable food sources and provide ecosystem services. However, their role in CO2 absorption or release is still debated. This study found that clams act as a moderate sink of CO2 over the year, with seasonal variability in fluxes. It suggests that seasonality and growth should be considered in shellfish farming for carbon markets.

Summary: This study uses a scope-for-growth-based model to estimate the budget terms of bivalve aquaculture as a carbon sink. The model is applied at 12 Mediterranean sites using operational oceanography data. Results show that mussels act as slight sinks if all components of the budget are considered. Differences in calcification and soft tissue contributions to the budget are related to site-specific factors, allowing for the creation of meta-models for optimal site selection.
