Summary: Sphagnum mosses in peatlands have varying responses to changes in atmospheric CO2 levels. Low water table hummocks benefit from increased CO2 concentration, while high water table levels suppress photorespiration. Water table levels play a key role in the response of mosses to CO2.

Summary: Ocean acidification has a severe impact on bivalve molluscs, particularly their shell calcification. This study examines the effects of elevated pCO2 conditions on the growth and calcification of the coastal mussel Septifer bilocularis at CO2 seeps in Japan. The results show that mussels living under high pCO2 conditions exhibit reduced condition index and shell growth, which are linked to changes in food sources and calcifying fluid carbonate chemistry.

Summary: The use of deuterium in the pharmaceutical industry has been expanding in recent years. This is due to the efforts of medicinal chemists to design compounds with improved metabolic profiles and increase the success rate of compounds in clinical trials. However, this expansion poses challenges for process and analytical chemists in tracking isotopologues and isotopomers to ensure the quality of intermediates and active pharmaceutical ingredients.

Summary: The study found that high light and eC(a) can independently improve the growth and photosynthetic performance of coffee plants, with some allometric changes observed under the combination of eC(a) and high light. Stimulation of photosynthetic rates by eC(a) did not directly affect stomatal and mesophyll conductances, and no signs of photosynthetic downregulation were found regardless of treatments.

Summary: Elevated CO2 levels can alter plant metabolism and affect herbivore insect performance. The study found that melon plants grown under eCO2 had lower nitrogen foliar concentration, higher carbon to nitrogen ratio, decreased amino acid content, and increased sucrose content. This led to reductions in population growth and body mass of Aphis gossypii, highlighting a negative response of this pest to eCO2 in a global change scenario.

Summary: Short-term studies can predict ecosystem responses to climate change, but the initial response may be a temporary overreaction, different from the later, more acclimated response. This study found that after four years of humidification treatment, the carbon sequestration capacity of the birch forest ecosystem stabilized, with understorey production increasing rapidly before ceasing growth.

Summary: This study quantifies the impacts of O-3, CO2 concentration, and meteorology on crop production and highlights the potential threat of air pollution to future food security. The results show that CO2 has the largest effect on crop yields, but this effect is offset by the negative impact of tropospheric O-3 in regions with high O-3 concentrations.

Summary: Increasing atmospheric CO2 enhances plant productivity, but nitrogen and phosphorus limitation can constrain plant responses to elevated CO2. In an experiment conducted in the Peak District National Park, grasslands with contrasting levels of phosphorus limitation showed different productivity responses to elevated CO2, with competition between plants and microbes for phosphorus playing a key role.

Summary: The Steptoean Positive Carbon Isotope Excursion (SPICE) event is a significant event in the Late Cambrian period, characterized by synchronous positive delta C-13(carb) and delta C-13(org) excursions worldwide. This study investigates the underlying mechanism of these isotope excursions using geochemical data from the Tarim Basin in China and other relevant sections. The study proposes that CO2 concentrating mechanisms developed in cyanobacteria in response to changes in pCO2 and pO2 during the SPICE event, leading to the synchronous positive excursions of delta C-13(carb) and delta C-13(org). The event also resulted in increased plankton abundance, potentially related to the activation of CO2 concentrating mechanisms and the maintenance of marine biodiversity.

Summary: There are multiple responses of atmospheric circulation to increased CO2. In the troposphere, the tropical upwelling region narrows, the Hadley cells expand, and the subtropical jet strengthens. In the stratosphere, the tropical upwelling region narrows and strengthens, enhancing the Brewer-Dobson circulation. However, the dynamical coupling between these features remains unclear, indicating independent circulation changes between the stratosphere and troposphere.

Summary: Nitrogen limitation is considered a constraint on terrestrial carbon uptake, but this study suggests that the decline in leaf-level photosynthetic N and leaf N content may not necessarily signify increasing N limitation, but rather be related to the rising CO2 concentration and temperature.

Summary: The study found that under elevated CO2 levels, DMPP and DMPSA NIs effectively reduce N2O emissions and maintain the stability of nitrogen in the soil, while also sustaining plant biomass production.

Summary: The study reveals the impacts of moderate or severe water deficit on the photosynthetic apparatus of Coffea canephora and Coffea arabica, showing that different genotypes have varying levels of tolerance to drought. Elevated CO2 levels can improve photosynthetic performance, particularly in terms of photochemical and biochemical components, while not significantly affecting photoprotective mechanisms and protein abundance.

Summary: Low-temperature thermal acclimation primarily occurs through adjustments in stomatal conductance, rather than changes in photosynthetic biochemistry. Increased leaf N concentrations have little effect on acclimation of photosynthesis or respiration.

Summary: As the concentration of CO2 in the atmosphere increases, there is a need to understand its impact on global plant transpiration in order to make better predictions. The complex interactions between CO2, climate, and plant physiology pose challenges in understanding the exact nature of this impact.

Summary: The Mediterranean diet is closely linked to socioecological practices, knowledge and tradition, promoting sustainable food production. Consumer adherence to this dietary pattern increases consumption of authentic premium foods, but the high-value recognition of these products can lead to economically motivated product adulteration, highlighting the importance of protecting the high added value of these unique food products.

Summary: Stable isotope abundances provide valuable information about plant physiological processes and environmental controls. By analyzing annual tree-ring series of Pinus nigra, we found that metabolic processes can affect hydrogen isotope abundances in glucose, and this effect is regulated by drought and atmospheric CO2 concentration. These findings enhance our understanding of how plant metabolism responds to environmental changes.

Summary: The Calvin-Benson cycle is crucial for carbon uptake in photosynthetic cells and has great significance for life on Earth. Recent research suggests the existence of a carbon flux from anaplerotic origin into the Calvin-Benson cycle. This study provides evidence supporting this anaplerotic carbon flux and suggests its role in maintaining ribulose 1,5-bisphosphate levels and counteracting oxidative stress.

Summary: This study estimated the carbon flux from the oxidative pentose phosphate pathway (OPPP) in chloroplasts into the Calvin-Benson cycle using isotopic analysis, and found that the isotope method underestimates the actual flux at low CO2 concentrations. The researchers then expanded existing models to account for the effects of OPPP metabolism on leaf carbon and energy metabolism in sunflowers. The results showed that OPPP flux increases both above and below a certain CO2 concentration, and the gas-exchange-based estimates are larger at low CO2 concentrations compared to the isotope-based estimates.
