Summary: Studies on the responses of soil organic carbon (SOC) and nitrogen dynamics to Holocene climate and environment in permafrost peatlands and/or wetlands might serve as analogues for future scenarios, and they can help predict the fate of the frozen SOC and nitrogen under a warming climate. Little is known about these issues on the Qinghai-Tibet Plateau (QTP). This study investigated the accumulations of SOC and nitrogen in a permafrost wetland on the northeastern QTP and analyzed their links with Holocene climatic and environmental changes.

Summary: This study investigated the source and sequestration flux of sediment organic carbon (SOC) in the Liaohe estuarine wetland by combining parameters of TOC/TN ratios, 813C, 815N, and 210Pb-chronology. The results showed that terrestrial input was the dominant source of organic carbon in the wetland. The sediment mass accumulation rate (MAR) and the sequestration flux of SOC (SF-SOC) exhibited overall increasing trends over time. These changes in sedimentation rate and carbon sequestration are attributed to human activities, such as the construction of reservoirs and dams.

Summary: Understanding the competitive adsorption behaviors of CH4, N2, and CO2 on montmorillonite is crucial for enhanced hydrocarbon recovery in clay-rich gas-shale reservoirs. CO2 showed the highest selectivity and was able to stimulate CH4 desorption. Lowering the temperature increased selectivity and facilitated desorption, while injecting favorably adsorbing gases triggered desorption more easily.

Summary: Wetlands are a significant source of methane emissions, and accurately estimating these emissions is crucial. This study presents a new upscaling model based on eddy covariance measurements to estimate wetland methane emissions globally. The model performed well, and its estimates were consistent with current models. However, there were discrepancies in tropical wetland emissions, indicating the need for additional data and improved knowledge in these regions.

Summary: This study examined the landscape changes and carbon budget of the Shanyutan wetland in Southeast China over the past 10 years. The results indicated that aquaculture ponds and bare land are carbon sources, while vegetated marshes act as carbon sinks. Due to degradation, the wetland has transitioned from being a carbon sink to a carbon source, with an increasing carbon efflux over time.

Summary: The study found that under a severely altered precipitation regime, CH4 flux decreased significantly due to reduced soil CH4 uptake and changes in microbial community structure, while under moderate changes, CO2 flux decreased likely as a result of enzyme activity suppression and alterations in microbial community structure. Contrary to expectations, CO2 fluxes were only slightly decreased under the severely altered precipitation regime due to differences in microbial strategies.

Summary: This study simulated the N2O emissions in different regions of the Qinghai-Tibetan Plateau using the TRIPLEX-GHG model and predicted its future trend. The results showed that the total natural N2O emissions slightly increased from 1970 to 2017, with the most significant increase in the northern and southeastern regions. Temperature was found to be the dominant factor for N2O emissions in high-altitude regions. It is projected that the natural N2O emissions of the Qinghai-Tibetan Plateau will continue to increase if the climate becomes warmer and wetter.

Summary: This study investigated the greenhouse gas emissions in wetland ecosystems (alpine peatlands) and found that water table levels and nitrogen deposition had different effects on CH4 and N2O emissions. The results suggest that if nitrogen deposition doubles in the future, the emissions of methane and nitrous oxide from alpine peatlands could significantly increase.
