Summary: The continuous release of CO2 into the atmosphere is causing the seawater to become more acidic, posing a threat to marine organisms such as echinoids. This review collected and summarized 50 articles on the effects of seawater acidification on adult echinoids, revealing that pH reduction can lead to various and subtle changes in calcification, physiology, behavior, and reproduction. More than 43% of the endpoints studied were altered by low pH conditions compared to control conditions. However, animals exposed in long-term experiments or residing in CO2-vent systems showed the ability to adapt. Furthermore, differences among species may be explained by the latitudinal range of their distribution. Therefore, future experiments should consider local variability, long-term exposure, and multigenerational approaches to better understand the effects of ocean acidification on echinoids.

Summary: The study found that mesophotic and shallow S. pistillata corals are genetically distinct and possess different symbiont types, with the former showing a greater capacity to cope with ocean acidification. Mesophotic corals were able to maintain unaltered metabolic rates under exposure to acidification conditions, showcasing their resilience to future OA challenges. Additionally, enhanced symbiont photochemical efficiency under high pCO(2) levels in mesophotic corals could contribute to preventing acidosis of host cells and supporting greater energy availability.

Summary: This study quantified the CO2 efflux of 318 tree species in a common garden setting and found that woody lignophyte trees had significantly higher CO2 efflux compared to other stem growth forms. The CO2 efflux did not differ among cycads, palms, and non-palm monocots. This suggests that using CO2 efflux estimates solely based on lignophyte trees may be inaccurate for understanding the carbon cycle in tropical forests.

Summary: Dark respiration (R-d) is a fundamental plant process that plays a crucial role in biomass gain and maintaining plant physiological activity. However, its response under severe plant water stress conditions is poorly understood. Increased leaf temperature, caused by decreased leaf transpiration, is an important driver of R-d. Additionally, water stress leads to a decrease in leaf carbohydrates, which serve as the main substrate for respiration. This study aimed to investigate the impact of water shortage on leaf R-d in grapevines and understand the factors influencing R-d under water stress conditions.

Summary: The study demonstrates that the ubiquitous coral Stylophora pistillata exhibits similar responses to acute and chronic thermal stress, primarily influenced by temperature treatment rather than duration or heating rate. Coral showed exceptional thermal tolerance, maintaining physiological performance up to 32 degrees C before suffering rapid tissue necrosis and mortality at 34.5 degrees C. The use of maximum quantum yield Fv/Fm measurements as a proxy for thermal tolerance could provide a systematic and standardized approach for comparing the upper thermal limits of reef-building corals.

Summary: This research aims to explore the hypothesis that shifts in assemblages of large benthic foraminifera (LBF) can detect early signs of degradation in the reef benthic habitat. Data collected from 12 islands in the Spermonde Archipelago in Indonesia between 1997 and 2018 were analyzed. The study found a clear temporal shift in LBF assemblages, which can reflect different habitat types dominated by corals or fleshy algae.

Summary: Extreme seawater temperatures are linked to increasing cnidarian bleaching, which is caused by a breakdown of the symbiosis between host and dinoflagellate symbionts. This study investigates the response of dinoflagellate symbionts to elevated temperatures and finds that there is a susceptibility to temperatures of 30°C, leading to decreased photochemical efficiency and cell density. Bleaching of coral holobionts at 30°C is explained by reduced density of algae cells in host tissue. Exposure to 34°C results in drastic bleaching and even death of corals, anemones, and jellyfish. The study emphasizes the important role of dinoflagellate symbionts in the response to elevated seawater temperatures.

Summary: Anthropogenic pressures are restructuring coral reefs globally, and the excretion of intestinal carbonates by marine fishes plays a relevant role in inorganic carbon cycling. This study identifies body mass and relative intestinal length as the strongest predictors of carbonate excretion in reef fishes. The mineralogical composition of the excreted carbonates is highly conserved within families but also influenced by temperature and intestine length. These findings improve our understanding of the drivers and contributions of fishes to inorganic carbon cycling in coral reefs.

Summary: This study investigates the potential to increase the content of peridinin and overall antioxidant activity in the up-side down jellyfish Cassiopea andromeda through the targeted application of different PAR intensities and UVB radiation. The results show that high PAR intensities decrease the concentration of peridinin, while the combined treatment of UVB radiation and intermediate PAR intensity significantly increases the concentration of peridinin and antioxidant activity. It is suggested that controlled and light-optimized cultivation of C. andromeda can be a new pathway to obtain valuable pigments and functional ingredients.

Summary: Caulerpa lentillifera, known as "sea grapes" or "green caviar", is a popular sea vegetable for consumption. The sea grape fronds are cultivated in ponds in Van Phong Bay, Vietnam during the dry season. Physical characteristics, such as frond weight, length, and rachis coloration, are important for grading the harvested sea grapes. Fronds of the best quality have longer and heavier fronds with darker rachis. Logistic regression analysis showed that frond weight was the best predictor of frond quality. The study provides a basis for improving harvest quality through cultivation and post-harvest protocols.

Summary: Sustainably managing fisheries requires evaluation of stock status, but many multispecies reef fisheries lack research and monitoring capacity to assess stocks against sustainable reference points. In this study, fish biomass data from >2000 coral reefs were used to estimate site-specific sustainable reference points for coral reef fisheries. The results show that >50% of sites and jurisdictions with available information have stocks of conservation concern. The study highlights the ecological benefits of increasing sustainability and provides a promising means for enhancing the sustainability of global coral reef fisheries.
