Summary: Global changes in precipitation patterns have increased flooding events, which have negative impacts on estuaries by reducing salinity levels and increasing nutrient inputs. Oysters, as important ecosystem engineers, are vulnerable to co-occurring environmental stressors associated with flooding events. However, the response of early life stages of oysters to multiple stressors is not well understood.

Summary: Predicting the impacts of multiple stressors and understanding their interactions is crucial for ecosystem management. However, the lack of a general framework hinders such predictions. Using process-based models, this study investigates the generalization of interaction types across different biological levels in a two-stressor experiment on a seagrass model system. The findings reveal that interactions can be synergistic, additive, or antagonistic depending on various factors, including initial conditions, experiment duration, stressor dynamics, and consumer presence. These results shed light on the challenges of identifying consistent predictors of non-additive interactions in natural environments.

Summary: The salinity gradient between marine and freshwater environments is an important ecological divide, and the mechanisms by which organisms adapt to new salinity environments are not well understood. In this study, researchers investigated how a particular type of microalgae called diatoms mitigate acute hypo-osmotic stress caused by sudden changes in salinity. They found that the transcriptome of the diatoms undergoes dramatic changes in response to the stress, with genes involved in cell growth and osmolyte production being repressed, while stress defense genes are induced. The gene expression largely returns to normal levels within a few hours, suggesting that gene expression dynamics can be used to predict acclimation. Furthermore, the study showed that the gene expression response to acute stress is different from the response after long-term acclimation to low salinity. Overall, this study provides insights into how diatoms adapt to natural salinity fluctuations and diversify in freshwater habitats.

Summary: Elevated temperature was found to be the primary driver of zebra mussel mortality, with salinity also increasing the likelihood of death. Stress-induced mortality in zebra mussels was associated with significant increases in the relative abundance of putative opportunistic bacterial pathogens, particularly Aeromonas. Shotgun sequencing and qPCR analyses showed that pathogenic Aeromonas species were significantly more abundant in temperature-induced dead zebra mussels.

Summary: This article examines the changes in seagrass beds in the Indian River Lagoon and their impact on the ecosystem. The study finds that seagrass area increased from 1994 to 2009, but percent cover decreased. However, between 2011 and 2019, seagrass area decreased significantly along with a decrease in percent cover. These changes were associated with phytoplankton blooms and stress caused by insufficient light. The loss of seagrass also resulted in increased nutrient availability for other primary producers. The recovery of seagrass beds may take a long time.

Summary: This study investigated the metabolic responses and osmoregulation mechanisms of the euryhaline bivalve hard clam to hypo-salinity stress using biochemical assays, metabolomics, and gene expression analysis. The results showed that during hypo-salinity stress, the clam developed vacuoles in its gills, decreased Na+ and Cl- concentrations, up-regulated Na+/Cl--ATPase activity, and down-regulated the cAMP-PKA pathway. Antioxidant metabolites were up-regulated, and glycerolipid metabolism was strengthened. Anaerobic metabolism and fatty acid β-oxidation were also observed. Potential biomarkers of hypo-salinity stress were identified. This study provides novel insights into the metabolic regulatory mechanisms of hypo-salinity stress in euryhaline bivalves.

Summary: Understanding the trophic links and interactions that ensure resilience of seagrass ecosystems to nutrient enrichment and trophic modifications is essential. Top-down processes, such as predation by top predatory fish species on mesograzers, appear to play a key role in maintaining the resilience of eelgrass meadows in the northern Baltic Sea. While the presence of multiple trophic pathways can provide additional resilience, future threats from local stressors and global environmental change may pose challenges to the continued resilience of these ecosystems.

Summary: This study evaluates the effects of bleaching on the oocytes of the Mussismilia harttii coral and investigates the strategies employed by these cells to maintain antioxidant balance and cellular homeostasis. The research finds that bleached coral oocytes experience lipid damage, but are still able to maintain their quality and potentially elongate their lifespan and fertilization capability. This response may be linked to an intensification of heterotrophy in bleached corals.
