Summary: This study found that recent mass coral bleaching events on the Great Barrier Reef have larger and more continuous spatial footprints than previous bleaching events, posing an unprecedented threat to coral species resilience. In contrast to the impacts of a severe tropical cyclone, the bleaching events isolated severely affected reefs from the nearest mildly affected reefs by greater distances, highlighting the significant threat to coral species posed by the spatial footprint of these recent bleaching events.

Summary: The study aims to determine the connectivity of coral reefs and the level of future coral cover under global scenarios of coral bleaching loss and potential recovery. The findings emphasize the importance of maintaining functional coral reef habitat outside of predicted climate refugia to sustain connectivity globally.

Summary: This study analyzed the heat stress on China's coral reefs in the South China Sea and the Beibu Gulf using an optimized Degree Heating Week (DHW) threshold. The results showed a significant increase in ocean warming rate in these areas, and the optimized threshold predicted more severe bleaching events with higher frequency.

Summary: This study comprehensively characterized coral-associated microbial aggregates (CAMAs) in Stylophora pistillata and found multiple coexisting Endozoicomonas phylotypes. These CAMAs enriched with phosphorus have different elemental compositions from coral tissues and symbiotic Symbiodiniaceae, highlighting their role in sequestering and cycling phosphate. The consensus metagenome-assembled genomes of dominant Endozoicomonas phylotypes confirmed their metabolic potential and genomic signatures related to polyphosphate accumulation and host association.

Summary: Seasonal forecasts of sea surface temperature have become crucial tools for reef managers to predict coral bleaching risk. The new thermal stress forecast products based on ACCESS-S1 provide critical advance warning of high thermal stress and increased coral bleaching risk. Degree Heating Months consider both magnitude and duration of thermal stress, impacting reef management and assessing different climate drivers.

Summary: Research utilizing color erasure detectors has demonstrated improved spatial resolution in imaging tasks beyond the diffraction limit. Experimental measurements using two telescopes showed a distance measurement of sources of different colors at 1.43 km, exceeding the diffraction limit of a single telescope by about 40 times.

Summary: The study found that coral recipients who received microbiome transplantation from heat-tolerant donors showed lower bleaching rates when exposed to short-term heat stress. Specific bacterial species from donors were identified in the microbial communities of recipients, indicating successful transmission. These findings suggest that recipient corals may preferentially take up putative bacterial symbionts, supporting resistance to heat stress more effectively than native symbionts. Further research is needed to understand the mechanisms underlying the beneficial effects of microbiome manipulation and to test the long-term persistence of these effects in field conditions.

Summary: Marine heatwaves cause coral bleaching and drive changes in tropical reefs. Little is known about how bleaching affects spatial patterns of organisms on reefs. We studied an uninhabited tropical island in the Pacific and found that bleaching increased biotic homogenisation and reduced spatial clustering of hard coral cover.

Summary: We tested a new instrument prototype that uses time-resolved chlorophyll-a fluorescence techniques and fluctuating light to characterize Symbiodiniaceae functional traits in seven different coral species. The system generated over 1000 dynamic measurements in a short time frame and revealed distinct phenotypes that corresponded to genus-level Symbiodiniaceae designations. By correlating the algal biometric data with bleaching response metrics, we identified biomarkers of thermal stress and trained a predictive model that showed high correlation when tested against coral fragments. This device and modeling pipeline could help improve the scalability of coral restoration programs.

Summary: This article presents a laboratory-based method for comparing the bleaching susceptibility of different coral species using a standardized image analysis protocol. By photographing and digitally analyzing coral samples, standardized grayscale values are determined and used to calculate relative grayscale and bleaching time index, indicating the corals' sensitivity to bleaching. The method was used to compare the bleaching susceptibility of five species and successfully ranked their sensitivity. The proposed method is easier and requires fewer replicates compared to other methods, making it a valuable tool for studying coral bleaching.

Summary: Stable oxygen isotopic ratios in corals can be used to reconstruct past climate variability. The contribution of seawater δ18O to coral δ18O variability is up to 89% in the Western Pacific Warm Pool. However, uncertainty in the δ18O(sw)-salinity relationship influences the inferred salinity variability.

The results demonstrate the superior performance of the proposed method in reconstructing spatial information from limited pixel resolution.

Summary: The study proposes a systematic approach to identify global forest restoration opportunities in order to reduce sediment runoff to coral reefs. Results show that coastal watersheds in Southeast Asian countries have significant sediment export impacts on coral reefs, and restoring forests could potentially decrease sediment input to 63,000 square kilometers of coral reefs.

Summary: This study compared the benthic communities of shallow and mesophotic depths in the Great Barrier Reef and the Western Coral Sea. It found initially a positive relationship between shallow and mesophotic coral cover, but this relationship became insignificant after multiple disturbances, with a significant decline in coral cover only at shallow depths. The study also revealed the dynamic nature of mesophotic communities, with their coral cover reflecting a balance between growth and mortality. The results highlight the urgency to expand coral reef monitoring efforts into mesophotic depths for better conservation management strategies.

Summary: The recent IPCC Special Reports provide an opportunity to understand a wide range of climate risks, with a scoring system developed to quantify global risk from climate change. By the end of the century, global climate risk is projected to substantially increase, with societal adaptation having the potential to reduce risk but not prevent it entirely. Different frameworks, including expert assessments from the IPCC, show a significant rise in global composite risk by 2100 under both low and high emissions scenarios.

Summary: The recovery of corals from oceanic thermal stress is correlated to their susceptibility to bleaching and their trophic strategy. Corals from different depths exhibit varied recovery characteristics, with shallow corals experiencing more severe stress while corals in mesophotic environments facing lower cumulative warming impacts.
