Summary: This study investigates the complex responses of corals to global change. The results suggest that tropical corals exhibit a reduced calcification response to increased pCO(2) when they lose their symbionts under high-temperature treatments. In contrast, a cold-water coral shows a negative calcification response to increasing pCO(2), which is partially alleviated under elevated temperature. All corals are able to elevate the pH of their calcifying fluid under increased pCO(2).

Summary: The majority of coralline algae experienced negative impacts like reduced abundance, calcification rates, and pH declines in response to ocean acidification (OA) in laboratory experiments or at naturally elevated CO2 sites. However, there were inconsistent physiological responses of coralline algae to simulated OA, with calcification/growth being the most frequently measured parameters.

Summary: Current experimental evidence suggests that coral reefs may disappear within the century if CO2 emissions remain high, but some corals may thrive under extreme conditions such as high temperatures, high pCO2 levels, and low oxygen levels. Unique study sites like volcanic CO2 vents, semi-enclosed lagoons, and mangrove estuaries provide opportunities to explore how reef species could adapt to climate change. Despite extreme environmental conditions, the Bourake lagoon in New Caledonia supports a diverse community of corals, sponges, and macroalgae, possibly due to environmental variability and nutrient imbalances.

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: This study investigated the importance of symbiotic metabolite supply to scleractinian corals and the effects of ocean acidification on coral calcification. The findings suggest that while there were no significant differences in carbon assimilation among different pH treatments, nitrogen assimilation significantly decreased at pH 7.4. This decreased nitrogen assimilation could lead to reduced coral resilience to stressful events, highlighting the trade-off between coral hosts and symbionts in response to future climate change.

Summary: The research found that under high CO2 conditions, the ratio of respiration to photosynthesis in Phaeodactylum tricornutum is higher and increases with rising temperature but decreases within a certain temperature range. This suggests that ocean acidification may exacerbate the negative impacts of warming on the R/P ratio in this diatom species.

Summary: The study found that under ocean acidification conditions, Ulva ohnoi algae prefer CO2 and NH4+ as carbon and nitrogen sources, leading to an increase in N content and better performance in photosynthesis and growth, thus potentially increasing their bloom potential; however, elevated temperatures decrease photosynthesis and growth, reducing their bloom potential.

Summary: Ocean warming and acidification pose a severe threat to pteropods in the Arctic by reducing their survival and causing the dissolution of their shells. Lipids, especially phospholipids, play a crucial role in the early-stage pteropods. Our experimental study shows that elevated temperatures and high CO2 concentrations lead to a significant decrease in total lipids, mainly due to the reduction of phospholipids. This reduction may compromise cell differentiation and energy balance in the early-stage larvae. The negative effects of warming on lipid metabolism may be a more immediate threat to pteropods than shell dissolution effects caused by acidification.

Summary: Cells communicate and reproduce sexually through the secretion of pheromones. In the yeast models Saccharomyces cerevisiae and Schizosaccharomyces pombe, pheromone signaling activates specific pathways involving receptors, small GTPase, and MAP kinase cascades. Local release and sensing of pheromones lead to spatial gradient interpretation and cell fusion. This review highlights the decoding of pheromone signals and the fusion process in these two yeast species.

Summary: Secretory vesicle clusters transported on actin filaments by myosin V motors play important roles in local secretion, and their focusing mechanism involves condensation mediated by an intrinsically disordered region (IDR) and selective permeability. This condensation mechanism may be a general mechanism for actin network organization and selective local concentration of secretory vesicles.

Summary: This study examined the impact of depth on the size and morphology of calcareous red macroalgae structures (rhodoliths) and the abundance of associated flora and fauna. The findings revealed that depth typically influenced the size and shape of rhodoliths, with larger nodules found at intermediate and deep depths. The biomass of attached macroalgae (epiphytes) also increased with depth. The study concluded that the morphology of rhodoliths and associated epibionts were primarily influenced by depth, regardless of latitude.

Summary: An innovative process using supercritical fluid chemistry was used to recycle uncured prepregs and functionalize the recovered carbon fibers with magnetic nanoparticles. This allows for the production of a new type of secondary raw material suitable for composite applications. The process also enables the fibers to be heated through induction for triggered healing properties and potential carbon fiber reclamation.

Summary: This study assessed the influence of environmental variables and human-induced pressures on infaunal community structure and functions in two main mangrove areas in Southern West Senegal. The study found that environmental variables and their temporal dynamics greatly impacted infaunal communities in the subtidal zone, while human activities had a greater effect on the intertidal area. Shellfish harvesting and heavy metals pollution resulted in a decline in abundance, biomass, taxonomic richness, and functional diversity of infaunal communities.

Summary: Biodiversity monitoring is important but costly and time-consuming. Taxonomic surrogacy can overcome these problems by accurately reflecting species-level community patterns, but its efficiency has rarely been assessed with long-term monitoring data. In this study, the efficiency of subset taxa in summarizing long-term community dynamics was tested in different coastal habitats. The results showed that Polychaeta best reflected the spatial and temporal dynamics of non-Polychaeta species, especially in biogenic habitats. The study confirmed the effectiveness of the subset-taxon method for reflecting long-term benthic habitat dynamics.

Summary: Global marine conservation is hindered by an imbalance in research efforts and policy actions, which limits progress towards sustainability. Rhodolith beds, despite their global ecological importance and numerous ecosystem functions, remain disproportionately understudied compared to other coastal ecosystems. The lack of information about these habitats and their ecosystem services hampers effective conservation measures, especially considering the severe pressures and threats they face. Therefore, it is crucial to prioritize research on rhodolith beds, combat degradation, and protect biodiversity for the future.
