Summary: The increased frequency of extreme weather variations worldwide has led to significant changes in soil water content. This study conducted a meta-analysis to explore the responses of soil CO2 and N2O emissions to drying and rewetting cycles (DWCs) at a global scale. The results showed that DWCs increased CO2 emissions, but had no significant effect on N2O emissions. Factors such as soil water-filled pore space during wetting, soil clay content, days of drying and wetting, and frequency of DWCs played a significant role in the emissions. Biotic and abiotic factors, such as carbon substrate availability and microbial activity, were identified as the main drivers of CO2 and N2O emissions, while soil gas diffusion and oxygen availability dominated N2O emissions.

Summary: This study assessed the contribution of three different rice cultivation practices (conventional, system of rice intensification, and zero-tillage) to carbon emissions. Results showed that fertilizer application significantly influenced greenhouse gas emissions, and all three cultivation strategies acted as carbon sinks, with the system of rice intensification yielding the highest carbon sequestration values. The ratio between ecosystem services and disservices was highest for the system of rice intensification, followed by zero-tillage and conventional cultivation.

Summary: The global carbon budget, which is crucial for studying climate change, is rapidly decreasing and likely to be depleted in the near future. The excessive use of non-renewable resources has contributed to this decline. However, there is a lack of studies examining the long-term impact of different sectors on the diminishing global carbon budget.

Summary: While traditional forest management focuses on timber production, sustainable forest management aims at the multiple benefits of forest landscapes. This study quantifies the economic trade-offs among natural, current, and re-wetted peatland forests using several indicators. The cost benefit analysis shows that drainage for wood production has caused significant economic loss compared to natural peatland forests, while re-wetting increases the economic value.

Summary: The two major concerns of sustainable agriculture are food security and climate warming. Straw incorporation is a commonly used field management measure, but its high carbon: nitrogen ratio poses issues. Ammoniated straw treatments aim to reduce the ratio, but studies on their long-term effects on maize grain yield and net greenhouse gas budget are limited.

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.

Summary: Peatland drainage depletes carbon stocks by increasing CO2 emissions, but restoration via re-wetting can reduce CO2 emissions and increase carbon storage. However, re-wetting also leads to increased methane emissions. Actively re-wetting disturbed peatlands is important for mitigating climate warming, as it can offset the radiative effect of CO2 sink strength with CH4 emissions on shorter time scales.

Summary: This review discusses the biogeochemical characteristics of tropical peatlands and explores the impacts of human activities such as deforestation, fire, drainage, and agriculture on these systems. Tropical peatlands store a significant amount of carbon, but they are increasingly threatened by anthropogenic modifications, which result in carbon loss, increased greenhouse gas emissions, and hydrological disruptions. With a warming climate, these impacts are expected to escalate, posing risks to carbon stocks in disturbed and intact peat swamps.

Summary: Although peatland drainage leads to carbon emissions, land subsidence, fires, and biodiversity loss, global drainage-based agriculture and forestry on peatland are still expanding. Rewetting and restoration of drained and degraded peatlands are urgently needed, but limitations in socio-economic conditions and hydrology hinder large-scale efforts, calling for a reevaluation of landscape use.

Summary: The study found that in tropical regions, CH4 emissions from reservoirs are primarily through bubble ebullition, with emission levels significantly influenced by spatial and temporal variability. High spatial resolution measurements are crucial for constraining CH4 estimates at the reservoir-wide level, and different upscaling approaches yielded similar results.

Summary: Plastic film mulching combined with biochar application has significant effects on the carbon budget, greenhouse gas emissions, and water use efficiency in farmland ecosystems. Plastic film mulching improves maize yield and greenhouse gas emissions, while the effect on the net ecosystem carbon budget is not significant. Compared to plastic film mulching alone, adding biochar and plastic film mulching reduces greenhouse gas emissions, increases soil carbon balance, and improves yield and water use efficiency.

Summary: Plastic film mulching can significantly increase crop productivity and net primary production, but it also leads to an increase in greenhouse gas emissions, resulting in a higher net global warming potential. Additionally, mulching can decrease soil carbon stock and increase carbon loss, but this negative impact can be alleviated with higher levels of biomass addition.

Summary: Reconstructions of past climate impact on peatland carbon dynamics show that the warming effect of CH4 emissions exceeds the cooling effect of CO2 uptake initially, but eventually the net effect becomes cooling. Uncertainties related to past CO2 flux, CH4 emission, and peatland expansion affect the reconstruction of peatland carbon dynamics. The largest uncertainty is associated with CH4 emissions, and high CH4 emissions and low C accumulation rates may lead to peatlands remaining as climate warming agents since their initiation.

Summary: This study analyzes the impact of economic and environmental indicators on carbon and greenhouse gas emissions in 29 OECD countries from 1990 to 2018. The findings suggest that export diversification has a negative effect on carbon emissions but promotes greenhouse gas emissions. Institutional quality, economic growth, financial development contribute to reducing carbon emissions but increasing greenhouse gas emissions. In contrast, trade openness has a positive influence on carbon emissions but a negative influence on greenhouse gas emissions. Additionally, urbanization is identified as one of the major factors contributing to environmental degradation.

Summary: The study investigated the variability of CH4 flux, the effects of CH4-related microbes on CH4 emissions, and the dependency of these effects on environmental conditions in the Zoige alpine wetland. The results showed significant correlations between microbial abundances and CH4 flux, as well as the influence of soil water content, C:N ratio, and DOC:TN ratio on CH4 emissions in the wetland ecosystem. The findings provide new insights into understanding the risks of high CH4 emissions from alpine wetlands under changing climatic conditions and anthropogenic disturbances.

Summary: Alpine meadows on the Qinghai-Tibetan Plateau are sensitive to climate change, particularly in response to changes in the precipitation regime. Severe changes in precipitation can significantly impact N2O fluxes, soil enzyme activity, microbial community structure, and nitrogen cycling, ultimately leading to increased N2O emissions. This study provides valuable insights into the complex interactions between precipitation regimes and N cycling in alpine ecosystems.

Summary: Extreme drought has significant effects on soil water content, soil microbial community structure and function, soil heterotrophic respiration (R-h), and soil methane (CH4) flux. This study investigated the responses of R-h, CH4 flux, and microbial community to extreme drought and identified the main factors influencing R-h and CH4 flux. The results suggest that bacterial functional groups play crucial roles in determining R-h and CH4 flux.

Summary: The combination of biochar and fertilizer has the potential to improve environmental quality and agricultural productivity. This study found that biochar and inorganic fertilizer had different effects on soil, with higher fertilizer application rates increasing bacterial gene abundance and nitrification and denitrification potential, while not affecting fungal genes. On the other hand, increased biochar application rates increased fungal activities but decreased bacterial genes and nitrification and denitrification potential, especially in the rhizosphere. Structural equation modeling showed that bacteria had a greater contribution to total denitrification than fungi in the non-rhizosphere, but the opposite trend was observed in the rhizosphere. These findings suggest that partially substituting inorganic fertilizers with biochar can reduce potential N2O production from bacterial nitrification and denitrification.

Summary: Elevational gradients have significant effects on the root traits of plants, but the responses vary among different traits and plant species. The coefficient of variation of root traits at the community level increases with elevation, and intraspecific variation plays a more important role. Intraspecific trait variation may drive plant community composition under global warming.

Summary: High-elevation ecosystems are experiencing an increase in non-native plant species, with an average increase of approximately 16% per decade. The direction and magnitude of range limit shifts depend on elevation, and upward shifts are observed in at least seven regions. This highlights the need to monitor and prevent biosecurity issues in high-elevation ecosystems.

Summary: Fire is a significant driver of biodiversity in forests and influences above-ground and below-ground communities. Our study used DNA sequencing to investigate the temporal responses of soil fungal communities to fire and found that the effects of fire on fungal communities are strongest in the short to medium term. Ectomycorrhizal fungi, which play important roles in forest ecosystems, were disproportionately impacted by fire compared to saprotrophs.

Summary: In this study, nematode diversity in forest soils was found to be mainly influenced by soil organic carbon content, but climatic factors such as temperature, soil phosphorus content, soil pH, and precipitation also played significant roles. Furthermore, there were differences in nematode diversity between different climatic zones. Therefore, high-resolution studies are necessary to accurately predict the response of soil functions when climate conditions exceed the coping range of soil organisms.

Summary: The study found that climate warming affects the exchange of carbon and nitrogen between Ericaceous shrubs and root-associated fungi. The effects of warming on this exchange depend on the form of nitrogen. In the short term, warming decreases the amount of carbon allocated to root-associated fungi per unit of glycine assimilated by the shrubs, but increases it per unit of moss assimilated.
