Summary: The study found that Porites astreoides, a dominant species in Caribbean reefs, displayed unique physiological adaptations in the regulation of electron transport chain in comparison to other common scleractinian corals during light/dark transitions. This unique adaptation, specifically in the dark phase, could be a key factor contributing to the species' ecological success and survival in the face of various environmental and anthropogenic threats.

Summary: Mass thermal bleaching events pose a primary threat to coral reefs, impacting energetics and reproduction. In a study on the French Polynesian island of Mo'orea, resistant and recovered coral colonies showed differences in energy reserves and reproductive potential following a severe bleaching event. Understanding these sublethal impacts is crucial for accurately predicting coral recovery rates and overall reef resilience post-disturbances.

Summary: This study confirmed the incorporation of polystyrene microparticles in coral tissue without apparent toxic effects. Further research is needed to assess the potential toxic effects of microplastic ingestion, as well as the possible mechanisms involved in their recognition and incorporation.

Summary: A 2-year study in subtropical Hong Kong waters revealed that external erosion caused by sea urchin grazing is the primary factor contributing to coral skeletal loss. Controlling the sea urchin population density is crucial to reducing coral erosion.

Summary: This study reported the deepest photosymbiotic scleractinian corals collected to date (172 m depth) and identified the associated symbiotic communities using amplicon sequencing. The results expand the reported depth range of photosynthetic scleractinian corals (0-172 m depth) and provide new insights on their symbiotic associations at lower depth extremes of tropical coral reefs.

Summary: This study examined the physiological and morphological variations in larvae of the coral Porites astreoides from shallow and mesophotic reefs in Bermuda. It found that larvae from mesophotic reefs had lower respiration rates, larger size, higher settlement success, and larger initial spat size compared to larvae from shallow reefs. Regardless of parental origin, all larvae had higher survival under mesophotic light conditions, indicating a potential longer larval life and further dispersal period. These results suggest that larvae from mesophotic Porites astreoides colonies are likely capable of reseeding shallow reefs in Bermuda, supporting the Deep Reef Refugia Hypothesis.

Summary: Coral reefs in southeast Florida have suffered from severe coral loss and reduced diversity due to disease outbreaks, bleaching events, and human activities. In response, there has been an increase in weedy coral species like Agaricia spp. and Porites spp. in the region. The abundance of Porites astreoides, in particular, has notably increased in St. Lucie Reef in Martin County, the northernmost boundary of Florida's Coral Reef. The genetic structure analysis of P. astreoides populations in southeast Florida suggests that the recent increase in abundance may be driven by successful genotypes with high fecundity and long-range dispersal.

Summary: Coral reefs, which occupy only 0.2% of the world's oceans, are the most diverse habitat per unit area and support an estimated 1-3 million species. However, they have experienced severe declines due to various factors like climate change, pollution, and overfishing. Porites astreoides, a shallow coral species, has thrived on Atlantic reefs and become a focal species in scientific studies. This review aims to identify key traits for its survival, compile its biology and ecology, and identify gaps in knowledge.

Summary: The study reveals that interactions between corals and macroalgae vary greatly across sites and seasons, with different coral species showing varying effects on macroalgae. It is important to consider seasonal fluctuations of macroalgae for understanding their overall long-term impacts.

Summary: Coral reefs worldwide are under threat from climate change, which leads to an increase in coral bleaching. Even the surviving corals can experience temporary reproductive failure for several years. We conducted long-term experiments in aquaria to study the impact of temperature, photosynthetically active radiation (PAR), and ultraviolet radiation (UVR) on the spawning patterns and reproductive physiology of the Hawaiian mushroom coral Lobactis scutaria. The results showed that warmer temperatures and filtering UVR altered the timing of spawning, warmer temperatures caused a drop in fertilisation success, and warmer temperatures and higher PAR negatively affected sperm and egg physiology. These findings highlight the urgent need for similar reproductive data to predict future trends in other coral species and emphasize the importance of addressing thermal stress from climate change to ensure the survival of reef-building corals.

Summary: This study presents eight Porites coral delta C-13 records from the northern South China Sea, showing a long-term decreasing trend in coral delta C-13 seasonality since the mid-late Holocene, consistent with changes in orbital-induced insolation seasonal amplitude. By excluding other factors, the study suggests that the increased coral delta C-13 seasonality during the mid-Holocene is due to metabolic effects. These findings have implications for using coral delta C-13 seasonality as an indicator for past insolation changes under different climatic backgrounds.

Summary: In this study, the reproductive biology of Lophelia pertusa and Madrepora oculata in the Mediterranean Sea was investigated for the first time using histological techniques. The results showed that Lophelia pertusa has a seasonal spawning in autumn to early winter, while Madrepora oculata has continuous reproduction. The difference in reproductive features between the two species is of paramount importance for conservation strategies.

Summary: This study tested the larval settlement responses of 15 coral species to 15 species of crustose coralline algae from the Great Barrier Reef. The results showed that CCA in the family Lithophyllaceae were the best inducers for most coral species. Taxonomic and habitat-specific associations were found, providing optimal coral-algal species pairings to increase the success of larval settlement for reef restoration.

Summary: Threatened by climate change and ocean warming, coral reef ecosystems have been shifting in geographic ranges toward a higher latitude area. This study focused on the microbial communities and their role in primary production in high-latitude coral habitats. The results showed that the community structure and assembly of bacterial and carbon-fixer communities were significantly influenced by environmental variables such as coral coverage, nitrite, DOC, and pH. The assembly processes were different between the surface and bottom water, with deterministic processes dominating in the surface water and stochastic processes dominating in the bottom water.
