Summary: Ocean acidification and warming are major global threats to coral reef ecosystems, and the combined effects of both are still poorly understood. This study evaluated the effects of ocean acidification, warming, and their combination on two branching reef corals, Acropora digitifera and Montipora digitata. The results showed that warming had a stronger impact on both coral species compared to ocean acidification, with A. digitifera being more vulnerable. Warming was the main stressor for increased mortality and decreased calcification in the ocean acidification + warming group, and the combined effects were additive in both species. The study suggests that the abundance and cover of M. digitata may increase while those of A. digitifera may decrease in the near future in Okinawa.

Summary: This research reveals that under decreased pH conditions, coral recruits undergo extensive physiological, morphological, and transcriptional changes, with stimulation of photosynthesis and endosymbiont growth, potentially linked to gene expression associated with photosynthates translocation.

Summary: This study evaluated the combined effects of pH, dissolved oxygen (DO) and temperature on the antioxidant responses of Mytilus coruscus, finding that all tested biochemical parameters were affected by these environmental stressors. Some parameters showed an initial increase followed by a decrease over time, while GSH content increased with decreasing pH, DO and increasing temperature. The mussels were adversely impacted by reduced pH, low DO and elevated temperature, as shown by the Index of Biological Response (IBR) results.

Summary: Organic solvents, such as ethanol, methanol, dimethyl sulfoxide, and dimethylformamide, are commonly used in aquatic toxicity tests. This study examined the effects of these solvents on the reef-building coral Montipora digitata. The results showed significant morphological and oxidative stress responses, raising concerns about the use of solvents in toxicity studies with corals.

Summary: This study explores the impact of ocean warming and acidification on seagrass and its associated bacteria. The results show that the synergistic effect of ocean warming and acidification leads to decreased vitality and chlorophyll content in seagrass, while the associated bacteria exhibit higher resistance. This study contributes to our understanding of the interaction between seagrass and bacteria and provides insight into predicting and preserving seagrass meadow ecosystems in response to global climate change.

Summary: Ocean warming is predicted to challenge marine organisms, especially when combined with ocean acidification. Thermal history determines the physiological adjustments of marine organisms to climate change, with warm-acclimated individuals conserving energy to adapt to warming. However, compensatory feeding disappears when warming is combined with ocean acidification.

Summary: This study used diaPASEF proteomics and 16S rRNA amplicon pyrosequencing technology to investigate the effects of BaP on Montipora digitate. The results showed that BaP impaired cellular antioxidant capacity, disrupted the GSH/GSSG cycle, and caused severe impairment of energy metabolism and protein degradation in coral polyps. BaP also downregulated the protein expression of SOD2 and mtHSP70 in zooxanthellae, leading to oxidative free radical accumulation and apoptosis. The study provides a comprehensive and reliable assessment of the effects of BaP on corals from a symbiotic perspective, and suggests new directions for coral research and protection.

Summary: Increasing atmospheric CO2 is causing major environmental changes in the ocean, affecting coral algae's ability to withstand thermal stress. Acclimation to chronic global change stressors will reduce the tolerance of coral algae to anomalous increases in temperature.

Summary: There is overwhelming evidence that tropical coral reefs are severely impacted by human induced climate change. Assessing the capability of reef-building corals to expand their tolerance limits to survive projected climate trajectories is critical for their protection and management. Developmental plasticity may provide a means by which corals could cope with projected ocean warming and acidification.

Summary: The study found a significant negative relationship between the metabolic rate and bacterial richness in oysters, with the bacterial community composition being influenced by metabolic rate, extracellular CO2, and extracellular pH. The effects of extracellular CO2 depended on genotype, and changes in metabolic rate aligned with a shift in ASVs abundance, indicating a clear relationship between host metabolism and the microbiome in oysters.

Summary: The authors utilize machine learning models to identify multifactor tipping points of global marine phytoplankton. The study reveals that temperature and carbon dioxide are the key risks, and predicts that the tipping points of production and resistance in tropical areas will be crossed by 2100.

Summary: This study found that marine animals exhibit behavioral impairments and avoidance responses when exposed to pH drop and stress metabolites, which can be interpreted as a behavioral cost. Further research is needed to confirm the effect size of the behavioral impairments caused by stress metabolites and to characterize their chemical nature.

Summary: The research found that reciprocal transplantations of Zoanthus within different depths did not significantly alter symbiont dynamics. Colonies from intertidal zones did not transition to shallow symbionts in new environments, but bleached and died. The stable symbiosis suggests that Zoanthus may have limited ability to switch to stress-tolerant micro-algae in response to climate change.

Summary: Coral research is transitioning to the genomic era, where effective pairing of high-quality genomes with taxonomic characterizations and ecological relevance is needed. Lack of a formal framework calls for consensus guidelines to reconcile different types of data, especially for the metaorganism nature of the coral holobiont. While exhaustive taxonomic characterization of all coral holobiont member species is currently not feasible, guidelines on minimal, recommended, and ideal-case descriptions will aid in future referencing and comparative studies.

Summary: The study conducted rapid, standardized heat tolerance assays on 229 colonies of Acropora cervicornis using coral bleaching automated stress systems, revealing a broad thermal tolerance range among individuals within the population, with highly reproducible rankings across independent tests. This suggests a potentially dominant role of fixed genetic effects in setting thermal tolerance and widespread distribution of tolerant individuals.

Summary: Anthropogenic climate change and environmental degradation are causing global degradation of coral reefs.
This Review explores how the natural adaptive capacity of coral holobionts can be utilized to combat the ongoing loss of coral reefs.
Emerging approaches such as standardized acute thermal stress assays, selective sexual propagation, coral probiotics, and environmental hardening show promise for feasible and scalable solutions.
