Summary: Through investigating the distribution of microplastics in the environment and inhabiting organisms, it was found that microplastics have a preferential enrichment in organisms and show a clear correlation with the symbiotic density in corals. Different species of corals exhibit differential stress responses to microplastics, with large-polyp corals showing higher tolerance.

Summary: This study investigated the symbiotic relationship between Carnian corals and zooxanthellae in the Italian Dolomites, revealing potential widespread occurrence of this partnership. The findings suggest that Carnian scleractinian corals exhibited ecological adaptations similar to modern symbiotic corals, indicating that coral-algal symbiosis may have preceded the reef bloom at the end of the Triassic.

Summary: This study used stable isotope labelling and NanoSIMS analysis to clarify how sulfate in seawater is assimilated by corals and zooxanthellae at the cellular level. The results showed that coral hosts can directly absorb sulfate ions without assistance from zooxanthellae, and that assimilated sulfur can be retained in corals for at least 2 days.

Summary: Pigments similar to green fluorescent protein play a crucial role in adjusting the light microclimate inside the tissue of corals, facilitating the photosynthetic adaptation of coral symbionts to different reef habitats and environmental conditions. This study quantified the spectral light environment within corals expressing GFP-like proteins from different light regimes. The results showed that both photoconvertible red fluorescent proteins and chromoproteins significantly alter the light environment within the coral tissue. The findings highlight the importance of these GFP-like proteins in fine-tuning the light conditions for photosynthesis and photoprotection in corals.

Summary: This study performed structural inferences to explore the potential rules underlying the carbon and nitrogen metabolism of beetle larvae by analyzing the bacterial structures. The analysis showed enrichment of certain bacteria in the larvae feces, which might be involved in plant growth promotion, nitrogen cycle modulation, and environmental protection. Correlation and association analyses revealed the potential influence of common fecal bacteria on carbon and nitrogen metabolism. Structural equation modeling identified bacterial groups associated with carbon and nitrogen metabolism in the feces. The study highlights the importance of larval fecal-enriched bacteria and common symbiotic bacteria in wood biomass carbon and nitrogen metabolism.

Summary: This study investigated the impact of antibiotic-induced disturbance on the coral mucus microbiota and found that the microbiome could recover within 2 weeks following exposure. The presence of algal symbionts seemed to play a role in influencing the reassembly process of the microbiome. This work is important in showing the resilience of the coral mucus microbiome following disturbance and highlighting the potential role of algal symbionts in microbial recovery.

Summary: This study examined the geochemical responses of tropical corals Acropora polystoma and Porites lichen to nutrient enrichment and depletion. Results showed that nutrient imbalances and depletions have an impact on the elemental and isotopic composition of coral skeletons, as well as the internal carbonate chemistry. Variations in nutrient concentration or imbalance can greatly affect reconstructed sea surface temperatures and ocean or calcification pH.

Summary: The study reveals the evolutionary process dominated by the co-option of genes that originated before the cnidarian diversification. Each of the three species of scleractinians appears to express a unique set of ancient genes, as well as a substantial proportion of independently evolved proteins. In addition, non-random clustering of multiple SOM proteins within scleractinian-specific branches suggests the conservation of protein function between distinct species.

Summary: Ocean acidification can have detrimental effects on the survival, moult, respiration, and metabolite profiles of phyllosoma larvae of the slipper lobster Thenus australiensis. In addition, it may impair the ability of phyllosomas to detect chemical cues of fresh jellyfish tissue, potentially leading to negative consequences for adult populations of this commercially important species.

Summary: This study collected seawater, sediments, and wild scleractinian corals from coral reef areas near Liuqiu Island, Taiwan to investigate the abundance, characteristics, and impacts of microplastics (MPs) on coral cover. The results showed high levels of MPs in the coral, seawater, and sediments, indicating a potential threat to coral reef ecosystems.

Summary: The study analyzed and compared the lipidomes of symbiotic dinoflagellates isolated from two types of cnidarians, revealing that the composition of glycolipids is species-specific and not influenced by the host's taxonomic position. On the other hand, the profile of betaine lipids may be affected by the host. Additionally, the molecular species of triacylglycerols from freshly isolated symbiotic dinoflagellates were determined for the first time, showing different acyl group compositions based on their position.

Summary: This study explored the use of underwater soundscapes as a remote sensing method to detect biological and anthropogenic activities in coral reefs. By analyzing long-duration recordings and utilizing techniques such as source separation and clustering, the study revealed the dynamics of biological sounds in coral reefs off Sesoko Island, Japan. The research found that biological sounds were more prominent in shallow-water reefs compared to upper-mesophotic reefs, but the latter had a diverse array of fish choruses and transient sounds, while being heavily interfered with by shipping noise.

Summary: In coral larvae, the presence of symbionts led to lower survivorship compared to those without symbionts when exposed to natural sunlight. This is likely due to reactive oxygen species produced by stress on the symbionts' photosynthetic apparatus causing higher levels of cellular damage and mortality rates under solar radiation.

Summary: The discovery of multi-species synchronous spawning on the Great Barrier Reef in the 1980s led to efforts to document spawning times globally. The Coral Spawning Database (CSD) compiles data from over 100 sites in the Indo-Pacific region to provide open access for studying coral reproductive biology. The CSD aims to accelerate understanding of coral reproduction and to establish a baseline for evaluating future changes in reproductive patterns.

Summary: Distinguishing coral species is important for various studies and effective ecosystem management. Despite challenges in species delimitation, this study on tabular Acropora corals shows that different lines of evidence can help identify species boundaries accurately. Results suggest that species of the genus Acropora are reproductively isolated and independently evolving units that can be distinguished morphologically.
