Summary: Despite progress in quantifying greenhouse gas emissions, existing estimates mostly focus on carbon dioxide and overlook the relevance of methane emissions from dry inland waters. This study provides a cross-continental estimate of methane emissions and identifies sediment organic matter content and moisture as the main controlling factors. Methane emissions from dry inland waters are consistently higher than those observed in adjacent uphill soils, and their contribution to total greenhouse gas emissions is similar across different types of aquatic systems. These findings highlight the importance of considering methane in the carbon cycle of dry sediments.

Summary: The rising atmospheric methane burden and the uncertainty surrounding its causes are the focus of this study. The researchers present a collection of new delta C-13(CH4) signatures for tropical wetlands and rice fields, which provide insights into isotopic variation and potential seasonal shifts. Long-term monitoring at two observatories in Bolivia and Botswana shows that biogenic methane sources, particularly wetlands, dominate the records. The findings suggest significant seasonal variation in tropical wetland delta C-13(CH4) signatures, highlighting the need to incorporate this variability into future global and regional models.

Summary: Wetlands in China have a high rate of carbon sequestration, but there is still a lack of understanding about the emissions of greenhouse gases (GHGs) from these ecosystems. In this study, 166 publications were synthesized to analyze the variability and drivers of GHGs emissions from wetlands in eight subdivisions of China. The results showed that CO2 emissions contributed the most to the global warming potential (GWP) of China's wetlands, and certain wetland subregions had a significant impact on the overall GWP. Correlation analysis revealed the influence of factors such as temperature, elevation, rainfall, water level, soil pH, and redox potential on CO2 and CH4 emissions. This research provides valuable insights for global GHGs inventories and understanding the response of wetland ecosystems to environmental and climate change.

Summary: Shallow lakes produce and emit significant amounts of methane, and methane-oxidizing bacteria play a role in reducing these emissions. However, the role of aquatic plants in methane oxidation is not well understood. This study compared methane oxidation rates and bacteria abundance associated with different types of aquatic plants. The results showed that various plant types have different rates of methane oxidation, and high biomass of macrophytes is associated with reduced methane concentration in the water.

Summary: Ion-adsorption rare earth mining leads to high levels of nitrogen, multiple metals, and strong acidic mine drainage, which have unclear impacts on microbial assembly and ecological functions. We studied river sediments from China's largest ion-adsorption rare earth mine and found that bacterial community assembly was weakly influenced by spatial dispersion. Dispersal limitation and homogeneous selection were the dominant ecological processes, and bacterial alpha diversity decreased with pollution. Bacteria developed survival strategies to adapt to the extreme environment, sustaining species diversity and community stability.

Summary: Meta-analyses suggest a global potential of cover crops to increase soil organic carbon (SOC) stocks. However, there is a large variation across studies, highlighting the need to understand the effect of cover crops on carbon sequestration under specific soil and climate conditions. A Danish long-term field experiment (LTE) and a mesocosm study were conducted to investigate the carbon sequestration potential of cover crops. The results showed that cover cropping for up two decades had negligible effect on SOC, but significant overall SOC increases were observed when cover crop carbon input exceeded certain rates. This suggests that agricultural management practices should be adopted to achieve sufficient cover crop carbon input.

Summary: Macrophytes play a vital role in lowland streams by reducing the transport of nutrients to vulnerable coastal areas. However, weed cutting practices in European streams have a negative impact on nutrient retention and ecosystem metabolism. A study in Denmark showed that weed cutting reduced nutrient uptake and decreased gross primary production and respiration rates. Understanding the effects of weed cutting is important for managing eutrophication in downstream coastal areas.

Summary: Biochar is a carbon-rich material produced from biomass through pyrolysis. It has been suggested as an effective long-term option to sequester CO2 for climate change mitigation. However, there is no universally applicable approach to measure its carbon sequestration efficiency. Guidelines on biochar quality have been developed to ensure its safe environmental use in agriculture. The hydrogen-to-organic C ratio is an important quality criterion widely used as a proxy for biochar stability.

Summary: The substantial climate change mitigation potential of restoring peatlands through rewetting and intensifying agriculture to reduce greenhouse gas (GHG) emissions is largely recognized. The green deal in Denmark aims at restoring 100 000 ha of peatlands by 2030. Recent advances established the functional relationship between hydrological regimes, i.e., water table depth (WTD), and CO(2 )and CH(4 )emissions. We lay the foundation of developing a high-resolution WTD map for Danish peatlands and derive a national GHG emission estimate for peat soils. The estimated annual GHG emissions are 2.6 MtCO(2)-eq, which is around 15 % lower than previous estimates. Alternative restoration scenarios and the prioritization of fields in the rewetting strategy significantly influence the GHG reduction potential.

Summary: This study investigated the correlation between different fractions of glomalin-related soil protein (GRSP) and fatty acid fractions in soil, as well as the impact of conservation agriculture practices on arbuscular mycorrhizal fungi (AMF) biomass and GRSP content. The results showed a positive correlation between easily extractable (EE) GRSP and phospholipid fatty acid (PLFA) 16:1 omega 5, indicating the complexity of GRSP dynamics and the need for further research. Additionally, mechanical soil management had a greater impact on AMF biomass and EE-GRSP compared to residue management, suggesting that tillage practices exert a stronger influence on AMF abundance and GRSP content than residue management.
