Summary: This study aimed to investigate the role of photorespiration and alternative photoprotection mechanisms in marine plants in response to ocean acidification. It found that under high CO2 conditions, photorespiration decreased while non-photochemical quenching increased. Environmental conditions and CO2 concentration also impacted the photosynthesis and respiration of the plants.

Summary: This study aimed to understand how the leaf lipid landscapes of dwarf eelgrass Zostera noltii are altered under predicted ocean warming and hypercapnic conditions. Warming and hypercapnic conditions resulted in a severe reduction in leaf total fatty acid content, but the combination of both stressors substantially alleviated this depletion. Changes in the lipid composition of all classes were observed, with warming causing decreases in polyunsaturated fatty acids, although the combination of conditions relieved this effect.

Summary: The ocean serves as a major sink for anthropogenic heat and carbon, but the trajectories of heat and CO2 uptake diverge over the 21st century due to regional differences in physical and chemical drivers. Regional variations in heat-to-carbon uptake ratios will result in coherent regional patterns for sea surface warming and acidification by the end of this century.

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: 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: This study aimed to estimate the potential risk of the combined effect of global change factors and microplastic pollution on the growth and development of the sea urchin P. lividus. The results showed that exposure to decreased pH and microplastic caused a significant decrease in larval growth, while an increase in water temperature added additional stress, resulting in lower growth and altered development of the sea urchin larvae. The combined stress of ocean warming, acidification, and microplastic pollution may threaten sea urchin populations and have a potential impact on coastal ecosystems.

Summary: The study found rapid adaptation of the copepod Acartia tonsa to ocean warming and acidification, but interactions between temperature and acidification in later generations limited full adaptation.

Summary: This study examines the stoichiometric responses of marine phytoplankton to elevated pCO(2) and warming, and finds that elevated pCO(2) increases C:N and C:P ratios and enhances phytoplankton growth rates. However, warming does not consistently alter phytoplankton elemental composition. These findings suggest a stoichiometric compensation mechanism for reduced oceanic carbon export due to declining primary production in the future.

Summary: The burning of fossil fuels is causing rapid global ocean warming and acidification, stressing the physiological limits and plasticity of many marine species. Antarctic species are particularly vulnerable to environmental changes, with warming affecting the growth rate of otoliths in juvenile emerald rockcod, while CO2-acidified seawater has no effect.

Summary: Long-term experimental investigations on the transgenerational plasticity (TGP) and transgenerational acclimatization to global change in marine invertebrates are sparse. The study revealed significant effects of ocean warming and acidification on sea urchins, with offspring from near-future climate conditions displaying smaller size and reduced physiological functions. The experiment also showed potential for genetic adaptation in surviving individuals after a pathogenic event, but raised concerns about negative parental effects and reduced population replenishment.

Summary: Projected rises in atmospheric CO2 concentration and minimum night-time temperatures may have important effects on plant carbon metabolism in the Antarctic Peninsula. The response of the two vascular plant species, Colobanthus quitensis and Deschampsia antarctica, to elevated CO2 levels and nocturnal warming were assessed. The results showed that C. quitensis had reduced photosynthesis under elevated CO2 or nocturnal warming, while D. antarctica was not affected. Changes in mitochondrial size and number were observed in both species. The study suggests that D. antarctica may be more successful than C. quitensis in adapting to climate change.

Summary: The study found that ocean acidification reduced shoal cohesion, with mixed-species shoals showing lower cohesion than temperate-only shoals under climate stressors. Tropical fish became bolder under ocean acidification, while temperate fish became bolder with increasing temperature, but ocean acidification dampened the boldness of temperate fish.

Summary: Seagrass science has evolved from a descriptive field to a more quantitative and predictive one, requiring a mechanistic understanding of environmental influences on metabolic networks. Environmental factors like light, temperature, and CO2 availability limit seagrass productivity, survival, and growth, while stress responses are important. Understanding seagrass responses to ocean acidification, climate warming, and eutrophication can help predict the trajectory of ecosystems in a changing world.

Summary: The study found that acute heat exposure leads to a more pronounced physiological decline in corals despite lower thermal doses, while placing temperature exposures in degree heating times can better compare differences in physiological metabolism. When temperatures exceed 32 degrees Celsius, the ratio of daily gross photosynthesis to respiration fell below 1 in corals.
