Summary: This study suggests vulnerability in eelgrass meadows of the Northeast USA due to changes in water temperature, with higher than average summer temperatures leading to a decrease in eelgrass presence.

Summary: Colocation of farmed shellfish in seagrass has potential benefits for habitat and food production, but the presence of seagrass may not significantly affect the performance of shellfish. Elevating shellfish above sediment can improve their survival and tissue growth.

Summary: Seagrasses are highly productive ecosystems that provide numerous benefits to the environment and people. This study evaluates the carbon storage capacity of Zostera noltii and Zostera marina in intertidal seagrass meadows in Scotland, finding that seagrass areas show enhanced carbon storage compared to reference unvegetated ones. However, the variability in carbon storage across depth, sites, and estuaries indicates a need for further research and effective management strategies.

Summary: Extreme ocean events caused by global warming are projected to intensify and may have severe consequences for marine ecosystems. This study focuses on the response of seagrass Zostera marina to ocean acidification in hot conditions using a combination of morphology, transcriptomics, and metabolomics. The results show that Z. marina adapts to ocean acidification and marine heatwaves by upregulating certain metabolic pathways and activating the antioxidant system.

Summary: This study used Pacific oysters as a model to investigate apoptotic responses and regulation mechanisms under short- and long-term CO2 exposure. The findings suggest a variety of apoptosis regulation mechanisms exist during different exposure periods, with CgBcl-XL playing a crucial antiapoptotic protein role under long-term CO2 exposure.

Summary: Environmental stress can lead to dysbiosis of the intestinal microflora, increasing host susceptibility to pathogens. Ocean acidification has a significant impact on the intestinal microflora of Pacific oysters, reducing the abundance of probiotic bacteria and increasing pathogenic species. This can exacerbate the susceptibility of oysters to pathogens and pose a challenge to host health.

Summary: This study aimed to investigate the role of photorespiration and alternative photoprotection mechanisms in marine plants in response to ocean acidification. It found that under high CO2 conditions, photorespiration decreased while non-photochemical quenching increased. Environmental conditions and CO2 concentration also impacted the photosynthesis and respiration of the plants.

Summary: The study found that bivalves need to adapt to the stressors of ocean acidification and Vibrio infection associated with anthropogenic climate change simultaneously. Phenotypic differences between families were observed, with larger larvae tending to perform better in corrosive seawater.

Summary: This study introduces a novel framework for characterizing the response of eelgrass ecosystems to environmental variability, evaluating the importance of different environmental metrics on eelgrass bioindicators. The researchers found that temperature, light, and water motion metrics uniquely impact eelgrass productivity and resilience, with temperature variability playing a significant role. These results highlight the complexity of ecosystem responses to global climate change and emphasize the importance of considering multiple environmental factors simultaneously.

Summary: This study investigates the combined effects of tralopyril and ocean acidification on marine organisms and ecosystems. The results show that the combined toxicity is between that of acidification and tralopyril alone. Exposure activates stress responses, affects energy metabolism and biomineralization, and has an impact on marine carbon cycling.

Summary: This study investigated the responses of Zostera marina seedlings to the stresses of seasonal temperature increase and ocean acidification. The findings revealed that under high temperature conditions, carotenoid biosynthesis was stimulated, while under ocean acidification, certain metabolic pathways were activated. When subjected to both stresses, seedlings mobilized various biosynthetic pathways to enhance adaptability and resilience.

Summary: This study successfully synchronized the reproductive development stage of Pacific oysters through a preconditioning process. The results showed that using a calcium reactor helped maintain water quality parameters within favorable ranges, but had no significant effect on the oysters' weight and condition index.

Summary: Since the Industrial Revolution, anthropogenic activities have resulted in increased atmospheric carbon dioxide (CO2) concentrations, contributing to ocean acidification (OA) and affecting marine organisms that rely on calcium carbonate (CaCO3). This study examined the histological, secretory, and transcriptional changes in adult oysters (Crassostrea gigas) exposed to normal and reduced pH conditions. The results showed a decrease in secretory activity and differential gene expression related to shell formation and biological processes when oysters were exposed to reduced pH conditions. This research highlights the importance of understanding the cellular and molecular mechanisms underlying adult oyster tolerance to low pH conditions.
