Summary: This study measured the atmospheric CO2 concentrations in a salt marsh in southern Brazil and analyzed the CO2 exchange fluxes between vegetation and the atmosphere using eddy correlation techniques. The results showed that the CO2 fluxes were modulated by transient atmospheric systems and surrounding water level variations. It was found that the salt marsh acted as a CO2 sink during daytime and a CO2 source during nighttime. The seasonal changes in CO2 fluxes were influenced by sunlight, temperature, marsh inundation, winds, and plant biomass.

Summary: This study investigated the carbon budget of a intensively managed, permanent grassland in Switzerland over 16 years and determined the most important drivers of the net ecosystem CO2 exchange. The study found that the grassland acted as a small carbon sink or was carbon neutral on average. The rating for the importance of this study is 8 out of 10.

Summary: Salt marshes play a key role in attenuating wave energy and promoting sedimentation necessary to potentially adapt to sea level rise. The soil surface elevation in the marsh region varies spatially and temporally as a function of marsh topography, inundation frequency, and distance to the salt marsh edge. The sedimentation rate reduces linearly shoreward and is highest around the mean high-water level, moving towards the edge of the salt marsh with marsh extension and increasing soil surface elevation.

Summary: Arctic tundra landscape types exhibit differences in CO2 and CH4 balances and warming potential. Seasonal shifts in carbon emissions help buffer annual carbon budget differences caused by site variability. The polygon site has the largest mean warming potential, followed by the drained lake basin site and the upland site.

Summary: This study provides direct measurements of evaporation from Standley Lake, revealing its seasonal patterns and the factors influencing it. Summer evaporation is mainly driven by diurnal variations in wind speed and the vapor pressure gradient, while fall and winter are influenced by negative sensible heat transfer. Overall, evaporation plays a significant role in the energy balance of Standley Lake.

Summary: Coastal mangrove wetlands, such as the one in Pichavaram, South India, are significant sources of atmospheric methane. The CH4 flux in these ecosystems is influenced by factors like air temperature, creek water dissolved oxygen, soil organic carbon, and redox potential. Tidal inundation and seasonal variations in atmospheric temperature and water salinity play key roles in affecting the CH4 flux in mangrove ecosystems like Pichavaram.

Summary: The study found that a salinity of 7% and 10% can promote the organic carbon release from reed biomass. The highest nitrate removal was observed at a salinity of 7%, and this removal rate increased from 54.06% to 74.37% after adding reed biomass. Additionally, the lowest nitrous oxide emission flux was also observed at this salinity, with a rate of 0.23 mg/(m2 h). Microbiological analysis showed that salinity had an impact on the microbial community, with an increase in the relative abundance of Chloroflexi and Actinobacteria and a decrease in Proteobacteria. The main functional genera of denitrification also changed with increasing salinity.

Summary: This study utilizes satellite data from NASA and ESA to analyze the contribution of mesoscale eddies to oceanic salt transport. Results show good agreement between the two missions in the tropics and subtropics, but discrepancies at higher latitudes point to the need for improved satellite technology to enhance resolution and observe eddy variability.

Summary: Investigating the response of net ecosystem productivity (NEP) to phenological variation for crop ecosystems is important for understanding the impact of climate change on agriculture. However, the controlling mechanisms for rotation cropland ecosystems have not been well understood. This study used a 16-year flux observation to explore the potential of carbon flux phenology (CFP) and abiotic factors in interpreting the interannual variability (IAV) of NEP. The results showed that NEP was significantly controlled by different factors in wheat and maize seasons, and the carbon budgets varied depending on the season.

Summary: This study analyzes the long-term variation in evapotranspiration (ET) and its responses to environmental conditions across four grassland ecosystems in China. The study finds that precipitation and relative humidity have a major influence on the annual ET variation in typical temperate grasslands and alpine meadow-steppes, while leaf area index is the dominant factor in alpine shrubland meadows. Additionally, net radiation plays a crucial role in annual ET variation in alpine marsh meadows. The findings contribute to a better understanding of the ET process and provide insights for modeling efforts.

Summary: This study evaluates the matching between flux footprints and target areas to address a major challenge in model-data integration. The researchers found that mismatches could introduce biases and advocate for footprint-awareness when using flux datasets. They propose a representativeness index based on evaluations to guide specific applications and data use.

Summary: The study found that climate change-driven disturbances in lakes can lead to increased nutrient loading, affecting ecosystem function. A fertilization experiment showed varying responses in phytoplankton chlorophyll a, dissolved oxygen, and zooplankton biomass during the fertilization period, with delayed declines in water transparency and fish abundance. This suggests that indirect effects of climate change altering nutrient inputs may impact many lakes in the future.

Summary: The study of a lake record in the Beringia region suggests that during the Last Glacial Maximum, temperatures were about 3 degrees Celsius colder than the pre-industrial era, with a smaller cooling compared to other parts of the Arctic. As the deglaciation period progressed, warming in Beringia was punctuated by abrupt events that were synchronous with events seen in Greenland ice cores. The region responds more strongly to North Atlantic freshwater forcing under modern-day, open-Bering Strait conditions, with recent warming not surpassing peak Holocene summer warmth.

Summary: This article analyzes data from 738 observation sites and finds that coastal ecosystems have a certain absorption effect on greenhouse gases in the atmosphere, but methane and nitrous oxide emissions counteract the absorption of carbon dioxide. Southeast Asia, North America, and Africa are identified as hotspots for coastal greenhouse gas absorption.

Summary: This study is part of a long-term research on the effects of nitrogen loading in a shallow temperate lagoon. The results show that nitrogen fixation rates associated with seagrass epiphytes are relatively high, despite the high nitrogen input from contaminated groundwater. Cyanobacteria play an important role in the epiphyte communities. The study also suggests that climatic variation contributes to inter-annual variation in nitrogen fixation rates.

Summary: This study found that potential nitrification rates in GoM marshes were more than 80 times higher than in NE salt marshes, with differences in abundances of AOA, comammox bacteria, and AOB between the two regions. The ratios of nitrifiers to total bacteria in NE were up to 80 times higher than in GoM, indicating differences in the relative importance of nitrifiers between the two systems.
