Summary: We studied the metabolic activity of Heterostegina depressa under different light conditions. The photosynthetic performance and isotope uptake of the specimens were measured. Light supply significantly affected the photosynthetic performance, while the photosymbionts and holobionts could survive and be reactivated after prolonged darkness. The assimilation of C-13-carbonate and N-15-nitrate is mainly controlled by the photosymbionts, while N-15-ammonium and C-13-glucose utilization is regulated by both the symbiont and the host cells.

Summary: The study found that the impact of microplastic on corals depends on the type of microplastic, coral species, and temperature. Microplastic fibers reduced the photosynthetic capability of Acropora sp., while exposure to microplastic spheres significantly improved photosynthetic performance in Seriatopora hystrix.

Summary: In this study, the composition and erosion activities on coral blocks in two coral reef gulfs in the eastern tropical Pacific were analyzed, revealing that the balance between bioerosion and calcification activities depends on rich trophic needs and environmental conditions, suggesting the unpredictable impact of contributing species on habitats.

Summary: The study suggests that the blue coral may become an important reef-builder under ocean warming due to its relative resistance to thermal stress and high skeletal density. Blue corals are locally distributed and may be underestimated in their ability to restore stressed reef environments.

Summary: This study evaluated the effects of ocean acidification and warming on the herbivorous gastropod Trochus niloticus, showing that both factors can lead to physiological disturbances, impaired immune functions, oxidative balance, neurotoxicity, and disorder of energy metabolism. Integrated biomarker response confirmed that the overall fitness of T. niloticus was deleteriously impacted and more stressed under the co-exposure condition, indicating potential long-term impairments to the viability of T. niloticus in the future ocean, leading to degradation of coral reef ecosystems.

Summary: Global coastal waters have seen a 10% decline in oxygen concentrations since the mid-twentieth century, with ocean warming expected to worsen this trend. Research on the reef-building coral, Orbicella faveolata, showed that hypoxia and elevated temperature led to reduced oxygen consumption, with simultaneous exposure resulting in a significant decrease. This suggests that increased temperature may intensify the negative impacts of hypoxia on O. faveolata.

Summary: This study found that the Great Barrier Reef is negatively impacted by the combined effects of the contaminant diuron and climate change, particularly affecting the physiological responses of corals, with photosynthesis being significantly affected. It suggests that water quality guideline values may need to be adjusted as climate conditions change.

Summary: Global change, including seawater temperature increase and oceanic pH decrease, is causing declines in coral reefs. Local stressors such as microplastics also impact coral ecosystems. The interactions between these global and local stressors are not well-known. This study examines the independent and combined effects of global change and microplastics on gene expression and microbial community composition in the endangered coral Acropora cervicornis.

Summary: Climate change affects the sexual reproduction and photosynthetic capacity of Red Sea coral, leading to changes in reproductive timing and synchronicity. Survival and metamorphosis rates of offspring reared under simulated conditions are significantly reduced, highlighting potential long-term impacts on the coral population.

Summary: Ocean warming significantly reduces successful symbiont infection and geometric diameter of Platygyra daedalea recruits, while high pCO(2) has little impact. There is an inverse relationship between symbiont infection rates and survivorship, particularly at high temperatures. The study also reveals a high degree of plasticity in early symbiosis with implications for coral-algal partnerships under future climatic conditions.

Summary: The study examines the role of algal symbiont shuffling and evolution in coral resilience to global warming and ocean acidification, highlighting that shuffling is more effective than evolution. It also reveals global vulnerability patterns due to the interaction of warming rate and adaptive capacity, emphasizing the importance of considering species' ability to adaptively respond to climate change in conservation decisions.

Summary: This study compares the changes in calcification and dissolution in the nature reserve reef in the Gulf of Eilat between 2000-2002 and 2015-2016. The results show an increase in calcification but a significant increase in nighttime dissolution in the latter period. This could be attributed to eutrophication caused by fish farming in the area, which led to the development of organisms and factors that contribute to dissolution.

Summary: The study reveals significant warming and persistent acidification in the open ocean of the northern South China Sea since the 1960s, leading to a slight decline in coral skeletal density while coral extension and calcification show an overall increasing trend. However, coral calcification has persistently decreased since the 1960s, indicating a pessimistic situation for corals in the northern South China Sea.

Summary: Ocean warming and acidification pose a severe threat to pteropods in the Arctic by reducing their survival and causing the dissolution of their shells. Lipids, especially phospholipids, play a crucial role in the early-stage pteropods. Our experimental study shows that elevated temperatures and high CO2 concentrations lead to a significant decrease in total lipids, mainly due to the reduction of phospholipids. This reduction may compromise cell differentiation and energy balance in the early-stage larvae. The negative effects of warming on lipid metabolism may be a more immediate threat to pteropods than shell dissolution effects caused by acidification.

Summary: The ocean serves as a major sink for anthropogenic heat and carbon, but the trajectories of heat and CO2 uptake diverge over the 21st century due to regional differences in physical and chemical drivers. Regional variations in heat-to-carbon uptake ratios will result in coherent regional patterns for sea surface warming and acidification by the end of this century.

Summary: The symbiotic relationship between corals and photosynthetic algae is crucial for coral reef ecosystems, but global warming poses a threat to this relationship. While individual corals can adapt to climate change, the speed of community-level acclimation may determine the future of corals on a regional scale. Our model predicts that current rates of acclimation are insufficient to protect corals from global warming.
