Summary: The cycling of soil organic matter and carbon in the soil is influenced by key macronutrients. Adding stoichiometrically balanced nutrients can affect microbial community metabolism and carbon use efficiency. Adding glucose-C increases the synthesis of other carbohydrates in soil, while adding C and N together increases peptide synthesis. The combination of C and P increases the synthesis of fatty acids. Inorganic nutrient enrichment causes significant shifts in microbial community metabolism, but the community shows significant metabolic flexibility.

Summary: In this study, the Multiple Element Limitation (MEL) model was used to examine the responses of 12 ecosystems to elevated CO2, warming, and changes in precipitation. The results showed that ecosystems responded synergistically to the combined effects of elevated CO2, warming, and decreased precipitation, while the response to the combined effects of elevated CO2, warming, and increased precipitation was additive. The study also analyzed the factors attributing to changes in ecosystem carbon based on nitrogen and phosphorus, and found that different ecosystems exhibit different C-nutrient interactions, which shape their carbon sequestration under simulated global change.

Summary: Analyzing over 5000 lakes globally, researchers have found that lakes preferentially retain phosphorous over nitrogen, exacerbating the imbalance of nutrient cycles caused by human activities. The greater retention of phosphorous leads to an elevation in the nitrogen to phosphorous ratio in lake outflows, further worsening the global ecosystem's nitrogen-phosphorous imbalance.

Summary: This study investigates the effects of soil acidification and alkalization on the nitrogen and phosphorus stoichiometry in grasslands. It reveals that precipitation modulates vegetation N:P stoichiometry through changes in soil pH. Dryer grasslands are more sensitive to changes in soil pH compared to wetter grasslands, leading to greater alterations in vegetation N:P ratios.

Summary: Grazing exclusion is an effective practice to enhance ecosystem carbon stocks in arid-semiarid degraded grasslands, but its effects in humid regions are largely unknown. A field experiment found that 6 months to 1 year of grazing exclusion increased carbon storage of plants and topsoils, resulting in 14.6% higher carbon stocks in enclosed grasslands compared to grazed areas. However, enclosures over 3-6 years contained 14.4% less ecosystem carbon stocks, primarily due to decreased soil carbon sequestration.

Summary: This study conducted a global meta-analysis of 603 pairwise observations to investigate the effects of warming on C:N:P stoichiometry in plant-soil-microorganism systems. The results showed that warming increased soil N:P and vector angle, but decreased plant shoot N:P and enzyme N:P. These effects were influenced by warming duration, magnitudes, ecosystem type, and soil depths, and the findings contribute to a better understanding of C, N, and P cycling processes in terrestrial ecosystems.

Summary: Aquatic plant nutrient concentrations can vary greatly, with Juncus bulbosus able to thrive in nutrient-dilute waters due to its high carbon-to-nutrient ratios and slow growth. Stoichiometric ratios of C, N, P, and C:N:P in Juncus bulbosus vary with the time of year, habitats, and organs, but do not differ significantly between growth forms. The mass development of J. bulbosus requires C, N, and P, regardless of the ecosystem, challenging previous studies that suggested only CO2 and NH4 were essential nutrients.

Summary: This study integrated different methods to investigate the distribution development of main deciduous oak species in China. The results revealed that certain mountains served as refugia during the Last Glacial Maximum, and present oak distribution may be influenced by local dispersal rather than long-distance migration. Climate was identified as the main influencing factor for oak migration, while human activities had limited impact. The study highlights the importance of considering physiological differences and migration dynamics when modeling the dynamics of different tree genera.

Summary: Vegetated coastal ecosystems (VCEs) in the Bohai Rim Region, China have high organic carbon sequestration rates and play a crucial role in blue carbon sequestration for climate change mitigation. However, assessing soil organic carbon (SOC) stocks at a large scale remains challenging, and the factors controlling SOC in VCEs are not well understood. This study estimated current and future SOC stocks in VCEs using a data-driven method and identified climate and soil salinity as the key controls on SOC stocks in the region.

Summary: Our study suggests that plastic film mulching and its residues in croplands do not pose a significant threat to food security, as the positive effects of the mulching practice outweigh any potential negative impacts. Although long-term use of plastic film mulching and urea nitrogen fertilization may have detrimental effects on crop growth, our experiment found no substantial differences in soil properties, maize growth, and yield between previously mulched and never-mulched plots.

Summary: This study found that current TEMs substantially underestimate the interannual variability (IAV) of GPP, especially in nonforest ecosystem types. One possible cause is that the models underestimate the changes of canopy physiology responding to climate change. The differences between the simulated and observed interannual variations of leaf area index (LAI) also contribute to the underestimation of IAV.

Summary: Conventional plastic mulch has benefits for crop production, but causes a significant amount of plastic waste. Soil-biodegradable plastic mulch (BDM) is a promising alternative as it can be tilled into the soil after harvest. However, there is still a lack of direct evidence on the complete degradation of BDM under natural conditions.

Summary: Coastal wetlands are important for global carbon cycling, but often face challenges from exotic plant invasion. This study investigated the effect of Spartina alterniflora invasion on microbial residues and their contribution to soil organic carbon (SOC) in different coastal wetland ecosystems. The invasion of S. alterniflora had varying impacts on microbial residue carbon accumulation in different wetlands. Overall, it significantly increased microbial residue carbon accumulation in marsh with native Phragmites australis, while showing minor impacts on mangroves with Kandelia candel and Avicennia marina. The response of microbial residues could be attributed to changes in edaphic conditions and plant inputs.

Summary: The effects of sea level rise on the biogeochemical cycling of Si in coastal wetlands are still poorly understood. This study found that the content of labile Si was lower in sediments compared to soils. The main contributor to labile Si in sediments was phytoliths and diatoms. The storage of labile Si in sediment was significantly lower than in soil, indicating that coastal wetlands are an important source of Si to the estuary.

Summary: Salinity has a suppressive effect on soil microbiota and low carbon limitation in high-salinity soils might cause less carbon loss. Increased available phosphorus can alleviate microbial carbon limitations. Changes in the microbial functional community demonstrated that microbial nutrient limitation and microbial biomass contribute more directly to promoting soil microbial respiration. These findings have significant implications for understanding carbon dynamics in coastal wetlands ecosystems under increased nutrient discharge and sea-level rise.

Summary: By conducting extensive field investigation and utilizing multiple statistical approaches, we mapped the distribution of soil organic carbon (SOC) in northern China's grasslands and explored its correlations with climatic factors, biological factors, human activity intensity (HAI), and soil physicochemical factors. Our findings revealed that soil chemical factors and soil physical factors were strongly correlated with SOC, while HAI had a significant negative impact on SOC. Unlike previous studies, we found that climatic factors indirectly affected SOC through their influence on biological factors. Soil physicochemical properties and HAI were identified as the dominant factors influencing SOC distribution in northern China's grasslands.

Summary: This study found that plant available silicon (ASi) content in coastal wetlands in China is mainly influenced by soil pH, particle size, and nutrients. Vegetation composition and plant-derived lignin have a minor effect on ASi patterns. Mean annual temperature and precipitation indirectly regulate ASi content by affecting soil geochemistry and nutrient distribution. Therefore, ASi distribution in China's coastal wetlands is mainly controlled by primary pedogenesis and specific weathering processes.
