Summary: This study investigates the settlement-promoting effect of Ca2+ on larvae of the brooding coral Pocillopora damicornis for the first time. It finds that treatment with 40 mM CaCl2 effectively promotes coral larval settlement and is comparable to the natural inducer, crustose coralline algae (CCA). However, high concentrations of CaCl2 have toxic effects on larval survival and growth, which can be minimized by optimizing concentration and exposure period.

Summary: By examining the physiological parameters of corals and zooxanthellae in Sanya Bay coral reef areas in winter and summer, it was found that water temperature and salinity were the main factors affecting their physiological variations. High temperature/low salinity aquatic environment in summer reduced the density and chlorophyll a+c2 content of zooxanthellae, resulting in high superoxide dismutase and caspase3 activities. Turbidity was also an important factor affecting the physiological characteristics of coral-zooxanthellae symbionts. Overall, these findings have important implications for understanding and protecting coral reef communities in Sanya Bay.

Summary: This study found that light intensity has a significant impact on larval behavior and settlement in mesophotic corals. Exposure to light conditions corresponding to shallow depths resulted in bleached larvae and reduced settlement rates. However, mesophotic juveniles showed good survival and physiological acclimation in deeper habitats. These findings highlight the importance of light in the successful recolonization of depth-generalist corals to shallow reefs.

Summary: The extensive use of sunscreen products has caused concerns about their environmental toxicity and the negative effects they have on ecologically important coral communities. Metabolomic analyses on Pocillopora damicornis exposed to the UV filter avobenzone (BM) revealed unidentified ions in the coral's metabolome. Further analysis found that BM-exposed corals had 57 ions with significantly different relative concentrations, including 17 BM derivatives and one major derivative, C16:0-dihydroBM. These findings suggest that BM exposure may impair the photosynthetic capacity of coral holobionts and that the impact of BM derivatives should be considered in future environmental assessments.

Summary: PAHs can have moderate but persistent effects on corals by triggering biological processes at the mRNA level. It is interesting that PAHs can activate the neuroendocrine system in corals and function as environmental hormones, which may contribute to stress responses in symbiotic association. Combined treatment of PAHs and heat has a more significant effect on corals and their algal symbionts by affecting antioxidant activity and photosynthesis.

Summary: High-latitude coral communities have the potential to serve as refuges during global climate change, but this is being hindered by the combined pressure of global climate and anthropogenic activities. A long-term monitoring study on coral communities along the Bailong Peninsula in the northern South China Sea revealed that corals have a scattered and uneven distribution pattern, but the growth of reef-building corals and coral recruitment are improving, which play important roles in regulating the structure of adult coral populations and promoting the development of coral communities. The Bailong Peninsula has the potential to become a refuge for corals if human activities impacting coral restoration potential are controlled.

Summary: The colony morphology of corals is significantly correlated with the corallite area, but not with the symbiodiniaceae density. Massive corals with large corallite area can ingest more food, leading to higher levels of total lipid content and unsaturated fatty acids. Branching corals are predominantly autotrophic and their total lipid content is positively correlated with the Symbiodiniaceae density. Bleached corals consume larger amounts of stored energy to maintain normal physiological functions.

Summary: The dispersal of coral larvae plays a vital role in population replenishment and reef recovery. This study investigated the responses of brooded larvae of Pocillopora damicornis to elevated temperature and pCO2 at different biological scales. The findings showed that heat stress led to bleaching and decreased respiration, photosynthesis, and autotrophy, while high pCO2 stimulated photosynthesis. Heat stress induced greater symbiont loss at ambient pCO2 than at high pCO2, suggesting pCO2-dependent bleaching patterns. The study also revealed host antioxidant responses and metabolic pathways, as well as downregulated genes in symbionts under heat stress and high pCO2.
