The Multi-Generational Effect of Seawater Acidification on Larval Development, Reproduction, Ingestion Rate, and ATPase Activity of Tigriopus japonicus Mori, 1938

Fei Li et al.

Summary: Ocean acidification poses a continuous threat to marine organisms. A study on the copepod Tigriopus japonicus Mori, 1938 found that prolonged exposure to a constant seawater acidification level enhanced their adaptation capacity, but exposure to descending pH levels gradually increased detrimental effects. This could lead to reduced energy transfer and potential impacts on the food chain.

Physiological and biochemical responses of clams to recurrent marine heatwaves

Ke Yang et al.

Summary: Marine heatwaves (MHWs) in the South China Sea have been increasing in frequency, intensity, and duration, impacting intertidal bivalves and ecosystems. The Manila clam, an important species in this region, has the ability to survive and adapt to MHWs events, triggering compensatory mechanisms to mitigate thermal stress. Physiological and molecular processes revealed the clam's response to MHWs, including changes in metabolic rate, antioxidant defense, and biomineralization. Certain genes associated with tolerance and fitness were down-regulated, indicating resistance to MHWs.

Short-Term Exposure to Combined Condition of Low Salinity and pH Affects ROS-Mediated Stress in Disk Abalone (Haliotis discus hannai)

Min Ju Kim et al.

Summary: Climate change can alter the salinity and pH in aquatic ecosystems, affecting osmotic regulation and antioxidant capacity. This study investigated the impact of low salinity (LS) and ocean acidification (OA) on the expression and activity of Na+/K+-ATPase (NKA) in abalone gill tissue and changes in hemolymph osmolarity over a short period. Results showed that LS led to decreased NKA expression, activity, and hemolymph osmolarity. However, there was no significant difference observed in mRNA expression or NKA activity between the control and OA groups. The combination of LS and OA induced higher oxidative stress, as evidenced by increased H2O2 levels and mRNA expression of antioxidant enzymes and caspase-7. Moreover, DNA damage and caspase-7 expression increased with longer exposure time, with the LS + OA group showing the highest levels. These findings suggest that the combination of low salinity and pH imposes more stress on organisms. Uncontrolled ROS-mediated stress can lead to cell death and DNA damage.

Biomarkers of Oxidative Stress and Antioxidant Defense

Sema Demirci-Cekic et al.

Summary: Reactive oxygen and nitrogen species produced during normal metabolism in the human body play important roles in signal transmission and the immune system, but an imbalance between oxidants and antioxidants can lead to oxidative stress and diseases. Maintaining a balanced antioxidant defense system is crucial for overall health and disease prevention.

Dynamic energy budget modeling of Atlantic surfclam, Spisula solidissima, under future ocean acidification and warming

Emilien Pousse et al.

Summary: A dynamic energy budget model was used to study the effects of ocean acidification on Atlantic surfclam bioenergetics. The simulation results showed that future warming and acidification conditions would result in faster growth and increased energy allocation for reproduction in young surfclams, but a reduction in maximum shell length and energy allocated to reproduction was observed by the beginning of the 22nd century according to the RCP 8.5 scenario.

Dongyao Cui et al.

Summary: This study investigated the responses of different sexes of farmed Strongylocentrotus intermedius to chronic CO2-induced seawater acidification. The results showed that seawater acidification had a pH-dependent effect on the growth rate, the numbers of mature gamete cells, and altered metabolic pathways of adult S. intermedius.

Responses of Ruditapes philippinarum to contamination by pharmaceutical drugs under ocean acidification scenario

Angela Almeida et al.

Summary: This study aimed to evaluate the impacts of pharmaceutical drugs and acidification on edible clams. The results showed that the combination of drugs had fewer impacts on the clams compared to when the drugs were acting alone. Acidification had negative effects on the clams, but it did not enhance the toxicity when combined with pharmaceutical drugs.

Is Ocean Acidification Really a Threat to Marine Calcifiers? A Systematic Review and Meta-Analysis of 980+Studies Spanning Two Decades

Jonathan Y. S. Leung et al.

Summary: This study comprehensively evaluates the impact of ocean acidification on calcifiers, finding that many calcifiers have strong tolerance to future ocean acidification and their adaptability has been underestimated. It is suggested that future research should focus on how marine organisms survive in an ocean acidification environment.

Global Carbon Budget 2022

Pierre Friedlingstein et al.

Summary: Accurately assessing anthropogenic carbon dioxide emissions is crucial for understanding the global carbon cycle, developing climate policies, and predicting climate change. This article describes the methodologies and data used to quantify the components of the global carbon budget and their uncertainties. The data for 2021 shows an increase in fossil fuel and land-use change emissions, as well as the impacts of the atmosphere, ocean, and terrestrial biosphere on carbon absorption.

CO2-induced low pH in an eastern oyster (Crassostrea virginica) hatchery positively affects reproductive development and larval survival but negatively affects larval shape and size, with no intergenerational linkages

Jeff C. Clements et al.

Summary: Studies in North America on the effects of CO2-induced low pH in bivalve aquaculture are mainly focused on the US Pacific coast, with limited research on species from the northwest Atlantic. Exposure to reduced pH was found to increase the rate of reproductive development in both male and female eastern oysters, but also led to higher larval survival, reduced shell height, and increased deformities during spawning, fertilization, and embryo incubation. Further research is needed to assess the bioeconomic implications of reduced pH on aquaculture operations in Atlantic Canada.

Transcriptomic analysis reveals the immune changes associated with reproduction in the clam Meretrix petechialis

Di Wang et al.

Summary: This study investigated the transcriptome and gene expression of the clam Meretrix petechialis pre-/post-spawning, revealing the influence of reproduction on the immune status of mollusks. Females up-regulated genes related to apoptosis, TLR signal pathway, and heat shock post-spawning, while males down-regulated complement-related genes. Additionally, both genders increased immune response levels to combat Vibrio infection post-spawning.
