Summary: In the semiarid steppe of Erguna, Inner Mongolia, increasing nitrogen input can significantly enhance ecosystem C exchange, but only when soil moisture exceeds a certain threshold. In addition to considering the interactions of water, temperature, and nitrogen, their synergistic effects also need to be taken into account. During the growing seasons, the number of days with soil moisture content higher than 15% accounted for only about one third.

Summary: The availability of nitrogen (N) has been found to influence the mineralization of soil organic carbon (C), but its effect on the decomposition of native soil organic C induced by labile C input (i.e., priming effect) remains unclear. This study investigated the impact of N supply rates on the magnitude and direction of the priming effect, and how this interacted with soil layers differing in organic C content. The results showed that N addition increased the priming effect up to a certain level, and this effect was greater in the surface layer of topsoil compared to the subsurface layer. These findings highlight the susceptibility of soil organic C to loss through N-enhanced priming.

Summary: Land-use/land-cover change has significant impacts on ecosystem services. The Grain-for-Green Programme in China aims to improve ecosystem services. The study in the Jinghe River basin shows decreases in farmland and degraded grassland, and an increase in forestland. Water yield, sediment control, and carbon storage have improved. Grassland restoration areas have better water yield than forestland restoration areas, but the sediment export is difficult to judge. Grasses are better vegetation for the Grain-for-Green Programme in the Loess Plateau. Trade-offs between water yield and sediment control should be considered.

Summary: Soils play a crucial role in ecosystem functioning and service provisioning. Plant diversity has positive effects on soil organic matter, but most studies have focused on topsoil and long-term studies are limited. This study investigated the impacts of plant diversity on soil carbon and nitrogen concentrations and stocks, and found that higher plant diversity increased carbon and nitrogen storage, particularly in the topsoil. The effects of plant diversity on soil organic matter became stronger over time and extended to subsoil layers.

Summary: The study found that irrigation in New Zealand significantly reduced soil carbon and nitrogen stocks, with greater losses observed at greater durations of irrigation and lower aridity levels. The impact of irrigation on soil C and N was negatively related to aridity, with increasingly significant carbon losses observed at sites with higher precipitation levels. The results suggest that a new equilibrium may be reached with lower carbon stocks in irrigated grasslands compared to unirrigated grasslands.

Summary: The restoration of degraded lands and minimizing land degradation are important tasks in global environmental land management schemes. Soil organic carbon (SOC) is a key indicator of soil productivity and influences soil ecosystem services. Detecting changes in SOC stock within a short timeframe presents a challenge for land managers. This study aimed to identify early indicators of changes in SOC stock and their drivers by synthesizing global data on the impacts of land use change on SOC fractions and soil structural properties. The conversion of arable lands to forests and grasslands resulted in a significant increase in SOC fractions and soil structural stability. The study also found that certain SOC fractions, particularly particulate organic C and organic carbon stored in small macroaggregates, were strongly correlated with total SOC and can serve as suitable indicators of short-term changes in SOC stock. Further field studies are needed to validate the findings of this study and assess the applicability of SOC metrics under different land use change scenarios.

Summary: Sodium-ion and potassium-ion batteries are potential alternatives to lithium-ion batteries in energy storage, with advantages of abundance and low cost of Na and K. However, the large size of Na+/K+ causes volume change of the hosting material, resulting in capacity decay. In this study, porous few-layer SnS2 nanosheets are grown on reduced graphene oxide, forming a SnS2-rGO sandwich structure. This nanostructure enables high and stable electrochemical cycling performance of SnS2-rGO. The effects of different conductive carbons and electrolyte additive on the electrochemical performance are also evaluated. This work provides guidelines for better NIBs and KIBs through optimized electrode structure, electrolyte additives, and carbon additives.

Summary: A defense priming mechanism is activated in plants only under heavy pathogenic invasion, reducing energy and material costs under low pathogen loads. In this study, the researchers discovered that the expression of PpWRKY40, a transcription factor, is increased by defense priming elicitors such as BABA, MeJA or BTH, leading to the upregulation of sucrose synthesis-related genes and increased sugar accumulation in postharvest peach fruit. Additionally, the activities of sorbitol catabolizing enzymes also increased, converting sorbitol into glucose and fructose. This defense priming mechanism improved the overall quality and antioxidant levels of the fruit.

Summary: Soil microbial diversity and community composition in alpine grasslands are mainly controlled by edaphic properties, soil microclimates, plant coverage, and root biomass. The effects of these factors vary with vegetation type, with soil pH being the main determinant in alpine meadow and soil total organic carbon playing a more important role in alpine steppe. Soil moisture directly affects bacterial diversity and community composition in the alpine meadow, while indirectly affecting bacterial diversity in the alpine steppe through its positive influence on TOC. Bacterial community composition is mainly influenced by soil pH and TOC, while fungal community composition is more determined by plant coverage and root biomass.

Summary: Increasing nitrogen deposition leads to linear increases in total N2O (N2OT) and nitrification-derived N2O (N2On) emissions, but linear decreases in denitrification-derived N2O (N2Od) emissions at different soil depths. N2On emissions are positively correlated with the proportion of N2On emitted from nitrification, while N2Od emissions are positively correlated with the abundance of narG and nirS genes. These findings provide insight into the mechanisms of N2OT emissions and emphasize the importance of considering different N transformation processes in predicting N2OT emissions in the context of enhanced N deposition.

Summary: Broadband waves in the auroral oval are a permanent feature, with amplitude and location variations related to the magnetosphere's global state. Observations from 10 July to 26 August 2021 show that the waves in the auroral oval increase in amplitude (1-3 orders of magnitude) and shift to lower latitudes (around 10 degrees) immediately following the end of each storm. The response time of the auroral-oval waves is found to be equal to or less than the effective revisiting time of FY-3E, which is approximately 45 minutes.
