Summary: The study found that ocean warming has a greater impact on the growth of marine diatom Thalassiosira weissflogii over long-term selection experiments compared to ocean acidification. Many temperature response traits were influenced by ocean warming, indicating that it is the main driver for the evolution of T. weissflogii. However, adaptations resulting from warming can be constrained by ocean acidification, leading to trade-offs in photochemical performances.

Summary: This study investigates the growth response of Arctic diatom Chaetoceros gelidus under varying CO2 and light levels. The results suggest that this species has a high adaptability to variable light levels and is capable of accumulating substantial amounts of organic carbon at low CO2 levels. Additionally, under nitrogen limitation, intracellular nitrogen resources may be recycled, resulting in an increased carbon-to-nitrogen ratio within the cells.

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: Ocean-related global change has impacted competition between key marine phytoplankton groups, with nutrient concentrations significantly affecting diatom-dinoflagellate competition. Diatoms exhibit competitive superiority at high nutrient concentrations, while dinoflagellates can become dominant at very high nutrient concentrations and highest temperatures.

Summary: This study investigated intraspecific multi-trait variability and plasticity of Alexandrium ostenfeldii and Skeletonema marinoi along a salinity gradient. Cell size contributed the most to trait composition, with A. ostenfeldii showing higher trait plasticity than S. marinoi and exhibiting higher cellular carbon content and C:P ratio at low salinity levels.

Summary: Oceanic nutrient cycles are coupled, and carbon-nitrogen-phosphorus stoichiometry is variable through space and time. Surface temperature and macronutrient availability are strong predictors of stoichiometry at high latitudes. There is systematic regulation of elemental stoichiometry among ocean ecosystems, but future changes remain uncertain.

Summary: This study measured the CO2-fixation of different groups of phytoplankton in the Southern Ocean and found that small phytoplankton play a significant role in carbon fixation and export, especially after intense diatom blooms. The results highlight the importance of further exploring the role of small cells in CO2-fixation and export in the Southern Ocean.

Summary: Marine phytoplankton exhibit diverse responses to simulated ocean acidification, with certain diatoms showing increased growth rate under high CO2 conditions, while coccolithophores and picoplanktonic cyanobacteria show insignificant response to elevated CO2 levels.

Summary: Variable trace metal concentrations in the Precambrian ocean were closely linked to oxygen availability. However, less is known about the drivers of seawater trace metal chemistry after the spread of complex life into the Phanerozoic eon. The dominance shift from green Archaeplastida to secondary endosymbiotic algae with red-algal-derived plastids in the transition from the Palaeozoic to the Mesozoic era resulted in major changes in ocean chemical buffering.

Summary: The study found that ocean acidification and warming have significant effects on the species composition and sinking rates of coastal phytoplankton assemblages. Changes in pCO(2) and temperature had individual and interactive effects on phytoplankton species composition and elemental stoichiometry.

Summary: Coccolithophores are abundant calcifying organisms in modern oceans and are important for marine biogeochemistry and the global carbon cycle. Emiliania huxleyi, also known as Gephyrocapsa huxleyi, is the primary model organism for coccolithophore research and has contributed to significant advancements in the field. Other species are also being explored as models for specific aspects of coccolithophore biology.

Summary: This study reveals that ocean acidification and warming are major environmental stressors, and the impact of warming on the growth responses of phytoplankton to ocean acidification is not well understood. The results show that high CO2 enhances the growth of Phaeodactylum tricornutum and Thalassiosira weissflogii, especially at optimum temperature. Furthermore, HC-grown cells require more energy and materials to maintain intracellular homeostasis and repair damage caused by unsuitable temperatures.

Summary: This study analyzed the lipidomic responses of a marine diatom to long-term ocean acidification conditions, revealing significant changes in lipid metabolites with down-regulation of MGDG and up-regulation of PG. The results suggest that lipid remodeling is an adaptation strategy of marine diatoms to ongoing ocean acidification, emphasizing the importance of understanding long-term lipid adaptation in marine producers for predicting ecological consequences of climate change.

Summary: This study used underwater video and environmental DNA technology to analyze fish assemblages in oyster aquaculture equipment and natural boulder habitats. The results showed that black sea bass, scup, and tautog were more frequently observed and in higher abundance on aquaculture equipment, while cunner were more common on boulders within the natural reef.

Summary: Sugar kelp cultivation on the east coast of North America is important for human consumption. The study examined the epibionts on sugar kelp and found that cultivable Vibrio spp. were limited to old sections of the kelp blades and were not human pathogens. Toxic cyanobacteria and dinoflagellate were not detected on the kelp. The study also identified potential pathogens and grazing organisms associated with sugar kelp.
