Summary: This study examined the physiological and behavioral responses of adult sea urchins from different marine environments to long-term acidification. The findings revealed variability in adaptation abilities to acidification among sea urchins from different locations, with acclimation observed over continued exposure. This suggests a plasticity in the responses of sea urchins to future predicted ocean acidification conditions.

Summary: The study found that the impacts of pharmaceutical discharge on aquatic systems interact with environmental conditions, such as ocean acidification, affecting the physiology, behavior, and DNA integrity of sea urchin larvae. Under reduced pH conditions, the negative impacts of fluoxetine exposure were attenuated, resulting in lower levels of DNA damage compared to ambient pH conditions. Antagonistic interactions were observed, with larvae exposed to both reduced pH and fluoxetine exhibiting better performance than those exposed to only one stressor.

Summary: The red sea urchin Mesocentrotus franciscanus exhibited transcriptomic plasticity under different temperatures, indicating their capacity for a molecular-level response to ocean warming as climate change continues. However, the lack of a robust transcriptomic response under elevated pCO(2) levels suggests that this species may be negatively affected by ocean acidification. High present-day pCO(2) conditions that occur due to coastal upwelling may already be influencing populations of M. franciscanus.

Summary: The study found rapid adaptation of the copepod Acartia tonsa to ocean warming and acidification, but interactions between temperature and acidification in later generations limited full adaptation.

Summary: Ocean acidification and eutrophication have a positive impact on the growth of marine macroalgae, potentially leading to macroalgal blooms and changes in ecosystem structure and function. Grazers play a role in controlling the growth of macroalgae, and evidence suggests that ocean acidification and eutrophication indirectly increase consumption rates. The experiment showed that increased pCO(2) resulted in reduced grazing rates on live macroalgae, with snails predominantly feeding on Ulva. Eutrophication did not affect consumption rates of live tissues. Additionally, dietary shifts in a changing climate may be driven by the physical characteristics of algal tissues rather than tissue chemistry.

Summary: This study aimed to estimate the potential risk of the combined effect of global change factors and microplastic pollution on the growth and development of the sea urchin P. lividus. The results showed that exposure to decreased pH and microplastic caused a significant decrease in larval growth, while an increase in water temperature added additional stress, resulting in lower growth and altered development of the sea urchin larvae. The combined stress of ocean warming, acidification, and microplastic pollution may threaten sea urchin populations and have a potential impact on coastal ecosystems.

Summary: Elevated pCO(2) has differential effects on the growth rate of diatoms, slowing down growth during the night but increasing it during the day. The increased pCO(2) enhances respiratory energy supplies and photosynthetic performance, but may also lead to higher death rates when cells sink to dark ocean regions.

Summary: This study analyzed the mitochondrial genome and transcriptome of deep-sea solitary coral Polymyces wellsi living in the oxygen minimum zone (OMZ) and showed the genetic mechanisms underlying its adaptation to low pH, low oxygen content, and extreme food limitation. The findings revealed positive selection and expansion of genes related to biomineralization, mitochondrial components, and ciliary motion, indicating their significance in facilitating the coral's adaptation to the stressors in the OMZ. Moreover, the study identified a novel bio-indicator, the increased isoelectric points of skeleton organic matrix proteins, which may reflect the adaptive capacity of the coral to external acidified seawater. Overall, this study provides insights into the adaptive mechanisms of deep-sea solitary corals and offers strategies for addressing global climate change.

Summary: The study demonstrates that otopetrins play a crucial role in the mineralization process by providing an exit route for protons released during the formation of CaCO3. Otop2l, expressed exclusively in calcifying primary mesenchymal cells (PMCs), is involved in skeletogenesis, and its knockdown impairs spicule formation. Otop2l displays unique features and strong activation by high extracellular pH, suggesting its adaptation to oceanic living conditions as a cellular proton extrusion machine.

Summary: Projected ocean acidification (OA) alters seawater chemistry and bio-toxicity of metal ions, but its effect on marine microalgae resilience to metal stress is unclear. This study examines the impact of OA on copper metabolism in Thalassiosira pseudonana. Results show that increased pCO(2) promotes growth and photosynthesis, but decreases copper accumulation and toxicity. The study also reveals alterations in copper detoxification strategies and enhanced antioxidant enzyme activities under elevated CO2. These findings provide insight into the bioremediation capacity of marine primary producers under climate change.

Summary: Recent studies have quantified eCA and its activity in oceans for the first time, suggesting its potential as a biochemical indicator in biomonitoring programs and future research studies. The influence of environmental stressors on phytoplankton eCA activity highlights the need for further research to better understand its role in the marine carbon cycle in changing oceans.
