Summary: The increased frequency of marine heat waves (MHWs) caused by global climate change poses a threat to the survival of economic bivalves, such as the bay scallop Argopecten irradians irradians in northern China. This study examined the cardiac performance, oxidative impairment, and molecular responses of bay scallop hearts under simulated MHWs. The findings revealed dynamic molecular responses at the transcriptome level and identified the crucial role of CALR in the thermotolerance of bay scallops.

Summary: Animals with distributed visual systems consolidate visual information early in their sensory-motor pathways, exhibiting the ability to detect visual cues but lacking spatial vision. Through studying the bay scallop Argopecten irradians, researchers found that they possess both spatial resolution and spatial vision, indicating neural representations of their visual surroundings in their sensory-motor circuits.

Summary: The study found that the genetic variations in bay scallop growth traits are mainly caused by additive effects for shell height and length, and by dominance effects for shell width and body weight. Including insignificant inbreeding in genomic prediction model is unnecessary, and it is suggested to optimize the genomic prediction model with likelihood ratio tests and cross-validation before practical application.

Summary: GWAS analysis revealed the genetic basis of shell color in bay scallops, identifying key SNPs mainly located on chromosome 7 and three candidate genes involved in shell pigmentation regulation. Gene expression analysis showed significant differences in the expression levels of candidate genes in mantle tissues of individuals with different shell colors, providing insights into the mechanism underlying shell color phenotype differences.

Summary: The selected Argopecten irradians showed significant improvements in body weight and adductor muscle wet weight compared to the control group. Analysis identified genes related to insulin signaling, immune pathways, and actin cytoskeleton regulation as potential factors contributing to growth improvement in the selected group.

Summary: The study identified 1,906 significant SNPs associated with thermal tolerance in bay scallops using GWAS, revealing potential regulatory genes for thermal tolerance improvement. The findings suggest that the AiPC4 gene may act as a positive regulator of thermal tolerance in bay scallops, providing valuable insights for molecular breeding aiming at enhancing thermal tolerance in this species.

Summary: This study investigated the antioxidant response of bay scallops to acute exposure to benzo[alpha]pyrene, a type of polycyclic aromatic hydrocarbon. The results showed that exposure to benzo[alpha]pyrene induced oxidative stress and tissue damage in bivalves, with high concentrations leading to apoptosis and cell damage. These findings suggest potential adverse effects of benzo[alpha]pyrene on marine bivalves and provide insights into its ecotoxicological effects.

Summary: In this study, a Foxl2 gene (designated as AiFoxl2) was cloned and characterized from the bay scallop Argopecten irradians irradians. The expression of AiFoxl2 was mainly detected in the ovary, with highest levels during the proliferative and growing stages. Knockdown of AiFoxl2 resulted in up-regulation of testis development-related genes and down-regulation of ovary development-related genes, indicating its role in ovarian development and differentiation in A. i. irradians.

Summary: In this study, the PC4 genes were successfully identified and characterized in bay scallops. The expression profiles of these genes in different developmental stages and under high-temperature stress were analyzed. The study provides insights into the molecular function allocation of PC4 in scallops and their response to thermal stress.

Summary: The bay scallop is an economically important bivalve species in aquaculture industry in China, with the highest annual yield. Through whole genomic resequencing analysis, researchers found that the selective breeds of bay scallop have lower levels of genomic polymorphism and increased linkage disequilibrium compared to the hatchery reference population. Selective sweep analysis revealed genes under selection in the two breeds, potentially contributing to improved growth and immunity performance.

Summary: The study conducted 26 cruises in a bay scallop farming area in the North Yellow Sea from 2015 to 2020 to investigate dissolved oxygen dynamics and controlling factors. Significant oxygen depletion was observed in the summer, primarily influenced by temperature, photosynthesis, and microbial respiration. The study suggested that hypoxia and acidification in coastal waters were closely associated with temperature-induced stratification under complex hydrodynamic processes.

Summary: The combined effects of ultrasound and bamboo leaf antioxidants on the quality maintenance of scallop muscle during cold storage were investigated. The results showed that the combination treatment effectively delayed protein and lipid oxidation, bacterial growth, and maintained better microstructure and texture characteristics, extending the shelf life of the scallops during storage at 4°C.

Summary: Members of the Tssk family were systematically identified in the commercially important scallop Argopecten irradians, showing potential pivotal roles in spermiogenesis in this species. The absence of Tssk6 and unique presence of Tssk7 in mollusks suggest Tssks may have diverse functions in different organisms. This study represents the first comprehensive analysis of the Tssk family in mollusks, providing valuable insights into their characteristics and expression profiles.

Summary: A two-year experiment was conducted to investigate the impact of Pollicipes pollicipes harvest on intertidal community structure and ecological diversity. The study found that intensive exploitation resulted in a decrease in P. pollicipes and Mytilus spp. coverage, while Chthamalus spp. and Corallina spp. increased. The recovery of P. pollicipes aggregations was slow and variable, but their coverage increased under non-extracted conditions.

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.
