Summary: The precipitation of carbonate minerals does not always result in CO2 emission, as dissolved inorganic carbon can be utilized by terrestrial aquatic phototrophs, forming an organic carbon sink. Little is known about the effects of this mechanism on carbon cycles in DIC-rich lakes, limiting our ability to accurately evaluate and predict the magnitude of this carbon sink.

Summary: The study found that autotrophic picoplankton groups generally had faster growth rates, while heterotrophic prokaryotes had slower growth rates. Different populations exhibited different growth characteristics in different seasons, such as Prochlorococcus showing the highest growth rates in winter, while Synechococcus had faster growth rates in spring.

Summary: The paper quantified the metabolic rates of Lake Geneva through a 6-month record of high-frequency dissolved oxygen measurements, revealing significant temporal variability and vertical partitioning of metabolism. Two new alternative methods were used to filter low-frequency internal motions and showed consistent metabolic estimates, expanding the range of the diel oxygen technique to large lakes.

Summary: Tree stem respiration (R-S) is important for forest carbon balance, but different methods have conflicting results on the fate of respired CO2. This study collected data on beech trees and found that the ratio of CO2 efflux to O-2 influx was consistently below unity, but internal fluxes did not bridge the gap. The results shed light on the uncertain fate of CO2 respired by parenchyma cells.

Summary: Pear production relies on precise controlled atmosphere storage technologies to control ripening and disorders. Metabolites in pear peel under specific storage conditions reflect disorder risk, with different storage conditions affecting fruit quality, ripeness, and metabolism.

Summary: Dissolved oxygen (DO) and partial pressure of CO2 (pCO(2)) were measured in a seagrass meadow in Southeast Asia, showing that the rates of gross primary production (GPP) and community respiration (CR) were higher than global means, while net community production (NCP) was similar. However, the relationship between NCP and GPP differed at lower and higher GPP levels. The autotrophic/heterotrophic status did not correspond well to the sink/source behavior of CO2, suggesting that other factors besides organic carbon metabolism influence carbon sequestration in seagrass meadows.

Summary: Continuous measurement of CO2 exchange at a mountain lake in eastern Austrian Alps for one year showed that the lake is a small source of atmospheric CO2, with highest emissions in fall. Results also illustrated the impact of surrounding landscape on lake-atmosphere flux measurements, emphasizing the need to consider biases caused by low-frequency contributions and local wind regimes in estimating CO2 evasion from lakes in complex topography.

Summary: The study explores a novel strategy to identify metabolically active interneurons, finding that most metabolically active FS cells belong to the non-accommodating AP-firing category. Enhancing spontaneous neuronal activity leads to increased DCF oxidation in interneurons.

Summary: Lakes play a significant role in the global climate, but the environmental drivers of CO2 concentrations along latitudinal and climate gradients are not well understood. This study investigated boreal, sub-Arctic, and high-Arctic lakes in Norway to better understand net heterotrophy and gas balance. The results showed that CO2 saturation levels varied more than O2 saturation levels, and the CO2:O2 ratio was mainly influenced by DOC concentration in boreal lakes and conductivity in sub-Arctic and high-Arctic lakes.

Summary: Respiratory viruses rely on host cells for replication and actively induce certain cellular functions for their own benefit, including modifying metabolic pathways such as glycolysis, fatty acid synthesis, and the tricarboxylic acid cycle. Studying the modifications of metabolic pathways mediated by these viruses can help identify potential targets and compounds for therapeutic approaches.

Summary: In this study, the researchers examine the impacts of ocean warming on the growth, metabolic rate, and gene expression of clownfish larvae. They find that larvae reared at higher temperatures grow and develop faster, exhibit higher metabolic rates, and have differential gene expression. These results indicate that future warming could alter clownfish development and have implications for larval dispersal and settlement time.

Summary: Using metabolic labeling and mass spectrometric analysis, we characterized the metabolic changes in mouse livers induced by UPRER. We found that under UPRER conditions, hepatic de novo lipogenesis and cholesterogenesis were reduced, and the liver uptake of fatty acids was from free fatty acids rather than whole glycerolipids. Additionally, the synthesis of most liver proteins was suppressed.

Summary: We have developed an autonomous in situ analyzer for seawater total alkalinity, which is crucial for understanding the ocean carbon cycle and carbon dioxide removal efforts. The analyzer is lightweight, reagent efficient, and can be used on long-term platforms. It has been tested and proven accurate, with the ability to measure alkalinity in remote areas over extended periods of time.

Summary: The Labrador Sea in the North Atlantic Ocean is one of the few regions where atmospheric oxygen can directly reach the deep ocean. The intense oxygen uptake during Labrador Sea Water (LSW) formation affects the properties of the outflowing deep western boundary current, which is crucial for the oxygen supply in the upper North Atlantic Deep Water layer. The southward export of newly formed LSW primarily occurs from March to August, and this direct LSW export route controls the seasonal oxygen increase in the outflow at 600 m depth.

Summary: Continental shelves are disproportionately affected by climate change and play a significant role in global air-sea carbon dioxide (CO2) fluxes. The Scotian Shelf, a mid-latitude region in the northwest North Atlantic, exhibits strong seasonality in CO2 partial pressure (pCO(2)), acting as a net source in contrast to global trends due to biological drawdown of dissolved inorganic carbon (DIC) in spring and temperature effects. Despite localized events such as coastal upwelling, pCO(2) remains relatively uniform across the shelf, with the regional model successfully reproducing seasonal patterns and simulating CO2 fluxes for different locations.
