Summary: The concurrent rise of conspicuous benthic cyanobacterial mats and coral diseases globally indicates the degradation of coral reefs. Recent research has shown a potential interaction between the expanding cyanobacterial mats and coral disease, particularly black band disease. This interaction poses urgent conservation concerns and challenges for future research.

Summary: This study characterized the coral-associated Symbiodiniaceae communities of 14 reef sites in Malaysia using high-throughput sequencing, revealing the predominance of Cladocopium and Durusdinium genera with high diversity and richness. Additionally, it was found that different ITS2-type profiles exist across coral species. By establishing a baseline for future studies, this research provides insight into the potential adaptive roles of coral-algal associations.

Summary: This study found that corals with specific symbiont lineages show distinct responses to thermal stress, with those dominated by Durusdinium being more resilient. However, Cladocopium symbionts exhibited better photosynthetic efficiency and carbon translocation in ambient temperatures, leading to faster growth and calcification. Symbiont shuffling under stress-induced changes may impact coral resilience, but the rapid environmental changes could outpace their evolutionary adaptation.

Summary: Research has shown that herbicides in the Great Barrier Reef have varying levels of inhibition on the photosynthetic efficiency and specific growth rate of coral endosymbionts, with PSII herbicides exhibiting significant toxicity while non-PSII herbicides have minimal impact. This data on the toxicity of Symbiodiniaceae will help improve water quality guidelines and herbicide management in tropical marine ecosystems.

Summary: The study utilized eDNA metabarcoding to investigate marine biodiversity distribution in Indonesia, revealing significant differences in biodiversity across locations with no discernible patterns in taxa distribution. Despite a relatively low success rate, the results highlighted unprecedented levels of marine biodiversity and significant differences in species composition.

Summary: Studies have shown that cyanobacterial mats significantly increase in coverage during coral bleaching events, but this change is temporary and quickly returns to normal levels within 6 months. The distribution of cyanobacterial mats is mainly limited to areas with slow water currents and is not directly associated with the extent of coral loss.

Summary: This study discovered a new symbiotic mechanism, the ayRhp1-mediated symbiosomal NH4+-trapping mechanism, which promotes nitrogen delivery to algae during the day for sustaining photosynthesis and restricts nitrogen delivery at night to keep algae under nitrogen limitation. Additionally, ayRhp1 facilitates CO2 diffusion, which may have implications for metabolic dysregulation and bleaching.

Summary: This study reports the archaeal associates of two sponges found in the coral reef ecosystems of Gulf of Mannar, India, with Nitrosopumilus sp. identified as the sole archaeal population associated with the sponges, Pseudoceratina purpurea and Cinachyra sp. Further investigation is needed to understand the host driven factors in selecting specific associates from a diverse group of archaea.

Summary: Tropical corals, as ecosystem engineers, are facing unprecedented challenges such as increasing disease prevalence and marine heatwaves. The interactions between coral holobiont's major symbiotic partners, the cnidarian host, Symbiodiniaceae algae, and the microbiome, influence trait variation and have physiological benefits. Understanding these interactions is challenging due to the extensive genetic variation and highly diverse microbiome of the coral holobiont.

Summary: Stony coral tissue loss disease (SCTLD) is a highly deadly and fast-spreading disease that affects Florida's Coral Reef and the wider Caribbean. Researchers are working together to find strategies to mitigate the spread of SCTLD, including using disease-resistant genotypes, genetic rescue, and therapeutics. Through experiments, they have found that antibiotic treatment can help reverse the damage caused by SCTLD and improve coral immune responses.

Summary: Ascidians are important marine sessile chordates in benthic ecosystems, with larvae preferring hydrophobic surfaces for settlement but not always suitable for attachment. Micro-scale structures or roughness may enhance larval settlement, while a nano-scale nipple array can significantly reduce attachment, hinting at similar functional structures on various invertebrates' body surfaces.

Summary: This study found that material with a synthetic nipple array structure has lower adsorption and adhesion forces in aquatic environments, which can reduce contamination on the surface of organisms. This characteristic is beneficial for survival in both aquatic and land environments.
