Summary: This study operationalized the SEV framework to assess the social-ecological implications of fishing and tourism in temperate coastal systems, highlighting the need for distinctive management intervention due to different dimensions contributing differently to the SEV. Livelihood diversification and marine areas protection are plausible strategies to build resilience in temperate coastal systems facing fishing and tourism pressures.

Summary: This study found that algal turf sediments from Lizard Island and Orpheus Island in the Great Barrier Reef contain various metals, and the loads of some metals increase significantly with turf length. These findings suggest that longer algal turfs could be an important pathway for these metals to enter food chains.

Summary: Marine urbanization often leads to increased artificial coastal defenses and heavy sedimentation, negatively impacting coral reef systems in tropical coastal cities. This study shows that fish assemblages on sloping granite seawalls differ from those on reef flats, with higher feeding activity on seawalls. However, elevated sediment loads may reduce feeding activity on the epilithic algal matrix, limiting its utility as a feeding ground for nearshore communities. These findings highlight the complexities and interactive effects of anthropogenic changes driven by coastal urbanization.

Summary: Biodiversity loss is negatively impacting ecosystem functions and services globally. This study focuses on the importance of co-occurrence of different functional groups in addition to functional diversity for the coral reef benthic state. The results suggest that protecting specific herbivorous fish functional groups is crucial for promoting coral accretion.

Summary: Reef degradation and algae-farming fish alter coral-algal-microbial communities. Microbial community analysis showed differences in dominant bacteria between fair and degraded reefs and damselfish territories. Important potential pathogens were found on the degraded reefs inside damselfish territories. Overall, this study provides valuable information for reef conservation and coastal management.

Summary: The study quantitatively scored coral reef resilience in Kenting National Park, Taiwan, using four different assessment frameworks, including biodiversity surveys and local expert opinions. Trends in resilience scores varied depending on the makeup of the assessment's indicators, with the Nanwan area showing high resilience. The most successful assessments were those that empirically quantified ecological processes and local factors with only a few indicators.

Summary: Coral reefs are heavily impacted by climate-induced disturbances, and the loss of coral reefs has a significant effect on people who rely on the ecosystem services they provide. However, the impacts of coral loss and the ability of individuals and businesses to adapt to it are not well understood, especially in the private sector. To address this gap, a survey was conducted among Australian reef tourism operators to understand their responses to severe bleaching and cyclone impacts. The results highlight the importance of response diversity, spatial heterogeneity, and learning for social-ecological resilience.

Summary: Research has shown that coral cover has a greater impact on the trophic structure of coral reef fish assemblages than fishing pressure, especially when environmental disturbances cause a decrease in coral cover. Benthic cover is significantly associated with fish biomass and various trophic components.

Summary: The study found that changes in the abundance of different symbiont genera within coral hosts can affect the gene expression of symbionts, particularly impacting expression of photosynthesis components and proteins related to cell movement. When both genera are represented in comparable proportions within the host, the mixed symbiosis state may lead to more intense competition but does not result in increased stress for the host. After heat treatment, corals with mixed symbiosis showed the lowest stress signatures compared to corals dominated by either Cladocopium or Durusdinium.

Summary: SDG 14 aims to secure marine sustainability by 2030, and understanding the changing seascape, global actions, and the collaboration between science and society are vital for achieving this goal in the Asia-Pacific region. Through a horizon scan, researchers identified nine emerging research priorities that can contribute to marine sustainability, including understanding seascape evolution, drivers of change, and the costs and benefits to people. Researchers can contribute by developing interdisciplinary understandings, emphasizing equity and justice, and improving knowledge of cross-scale processes.

Summary: The microbiota in the epilithic algal matrix (EAM) plays a crucial role in the biogeochemical cycling of nutrients in coral reef ecosystems. This study explored the microbial community of EAMs in the Luhuitou fringing reef in Sanya, China, and found that the composition of the microbial community varies with different phenotypes of EAMs and algal length. The ecological function of the EAM microbiota shifts from autotrophic to pathogenic as algal length increases.

Summary: Corals are important habitat-building organisms in tropical reefs, supporting a quarter of all ocean species and providing ecosystem services to millions of people. However, marine heat waves threaten coral reefs by killing individual colonies and reducing diversity. This study used aerial imaging spectroscopy to monitor coral mortality during a major heat wave in Hawaii, and found that certain reefs had lower coral loss and therefore may serve as refugia. Human and environmental factors, such as coastal development and sedimentation levels, played a role in differentiating resilient reefs from more vulnerable ones.

Summary: Algal turfs are a productive component of coral reef ecosystems, with depth being the primary driver of turf productivity rates and turnover mainly related to turf biomass. However, limited data availability and methodological constraints constrain our understanding of their productivity. Addressing these challenges is crucial for improving our knowledge of algal turf dynamics on coral reefs.

Summary: This study investigates the temporal variability in reef resilience of the Nansha atolls in the tropical western Pacific by integrating paleo-ecological reconstruction, historical mortality evidence, and ecological survey data. The results show long-term stability in community structure and persistence of reef resilience, with no evidence of community shifts attributable to centennial-scale changes in El Nino variability. However, recent ecological surveys reveal a major collapse in the reef ecosystem, particularly related to strong/extreme El Nino episodes.

Summary: Climate change is causing global decline in coral reef ecosystems. It is crucial to reduce CO2 emissions and implement local management actions to support reef health and recovery. Resilience assessments quantify the context of reefs and help marine managers anticipate changes and prioritize management actions.

Summary: This study investigated the life history traits of the Pacific longnose parrotfish, Hipposcarus longiceps, in the subtropical waters of the Yaeyama region, Japan. The findings revealed that compared to tropical populations, the Yaeyama population of H. longiceps has a longer lifespan, grows larger, and matures and changes sex later. It was also confirmed that H. longiceps has a distinct spawning period when the average water temperature is >= 24.6 degrees C. These findings suggest that global warming could potentially affect the spawning season of subtropical populations of H. longiceps.
