Summary: The study examined the relationship between carbon use efficiency (CUE) and water use efficiency (WUE) of karst vegetation in China and climate change. It was found that CUE increased with precipitation, while WUE decreased with solar radiation. There were differences in CUE and WUE among different land use types, with grassland having higher CUE and lower WUE compared to forest land. This study contributes to understanding the responses of ecosystems in karst areas to climate change, optimizing water and soil resources management, and promoting the healthy development of the ecological environment.

Summary: The responses of ecosystem water use efficiency (WUE) to environmental perturbations are nonlinear and depend on the strength of the coupling between water and carbon cycles. Two explainable machine learning models were used to evaluate the structure of these nonlinearities and assess the effects of temperature, precipitation, radiation, CO2 concentration, and nitrogen deposition on WUE. The findings showed that precipitation plays a dominant role in shaping the spatial pattern of WUE, while temperature and radiation have negative effects. The study also identified key sensitivities and thresholds in WUE to environmental controls over space and time.

Summary: Currently, agriculture accounts for a large portion of global water resources and creates high demand for freshwater in the Mediterranean area. This study evaluates the water consumption and pollution of olives, grapes, and tomatoes, common traditional crops in Southern Italy and the Mediterranean region, using the Water Footprint methodology. The study also predicts the effects of climate change on the Water Footprint of these crops and proposes scenarios to reduce water usage. The results show that olives have the highest Water Footprint value and grapes are most affected by climate change. Additionally, a Circular Economy proposal suggests that reusing wastewater can save up to 70% of water resources.

Summary: This study investigates the response of Pinus tabulaeformis productivity and water use to climate change. It reveals that the growth of Pinus tabulaeformis is more sensitive to temperature and that temperature has a positive effect on net primary productivity (NPP) and intrinsic water use efficiency (iWUE). Precipitation has a minimal effect on NPP and iWUE. Resistance is positively correlated with recovery, resilience, and iWUE, but negatively correlated with NPP. Overall, this study provides valuable insights into the carbon sink and water-carbon trade-off of plantations.

Summary: This study analyzes the stability of water use efficiency (WUE) in China, focusing on the National Forest Protection Project (NFPP) areas. The results show that stable WUE is mainly characterized by non-significant trends and increasing trends, promoted by precipitation and soil moisture. Unstable WUE, on the other hand, is dominated by positive or negative reversals of WUE trends, influenced by temperature, radiation, and saturation water vapor pressure difference. These findings highlight the need to improve ecological restoration programs to mitigate the negative climate impact on WUE stability.

Summary: The present study compared the effects of two barnyard millet varieties on the fertility and physicochemical properties of alkaline soil in Ningxia, China. The results showed that both millet varieties improved soil fertility by reducing alkalinity and pH, while increasing organic matter. The analysis of bacterial communities revealed no difference in diversity between the two varieties, but differences in relative abundance of certain genera. Metabolomic analysis identified enriched pathways related to alkaloid biosynthesis and amino acid metabolism. This study suggests that both millet varieties contribute to the reclamation of saline-alkali soil.

Summary: Overfertilization is common in rainfed apple orchards on China's Loess Plateau, but its impacts on soil physicochemical properties in deep soil profiles are poorly understood. This study found that different land-use types showed divergent distribution patterns in soil properties, with low variability for SWC and pH, moderate variability for NH4+-N, AP, and AK, and high variability for SOC, NO3--N, and EC. The results also showed that fertilization influenced soil water content, NO3--N, AP, and AK, and NO3--N played a crucial role in regulating pH and EC. Soil profiles were useful for studying the evolution of soil quality.

Summary: The Mediterranean region is expected to experience more intense rainfall events and severe droughts due to climate change, leading to an increase in runoff and erosion rates in agrosystems. Vegetation cover can help reduce erosion and the soil seed bank can provide cost-effective vegetation. This study assessed the effect of vegetation cover on seed loss in vineyards and evaluated the differences in the soil seed bank along a transect. The results suggest that vegetation may not protect interrows from runoff-induced seed loss.

Summary: This research introduces a hybrid four-sub-deep neural network (HFSD) model for partitioning NEE into GPP and ER. The HFSD employs dual sub-deep neural networks to estimate ERa and ERb and incorporates GPP and environmental variables to predict vegetation transpiration. The results of the model show that the dual sub-DNNs architecture enhances the accuracy of ER simulations, while using EC-derived T as a constraint improves the accuracy of GPP simulations. Correlation analyses suggest that solar radiation and air temperature primarily influence the seasonal variations in GPP and ER, while soil moisture has a strong impact during dry seasons. This study advances the biophysical description of data-driven models for NEE partitioning and enhances the accuracy of GPP and ER estimates.

Summary: Proper bed substrate selection is crucial for the performance of constructed wetlands, especially when treating drainage water with high nitrogen and low carbon and phosphorus concentrations. In a field-scale pilot plant, adding a carbon-rich substrate such as soil or biochar increased phosphorus availability in beds. Beds with soil displayed higher microbial density and activity, as well as better plant growth compared to gravel. These findings highlight the importance of selecting suitable substrates for treating irrigated agricultural water.

Summary: Considerable advances have been made in the assessment and mapping of soil organic carbon stocks. However, the rates of change in carbon stocks are influenced by various factors and need to be quantified. This study found that sandy soils under cultivation and forests have different organic carbon stocks. Factors such as tillage, irrigation, and nitrogen applications contribute to the decline in soil organic carbon stocks. Afforestation of abandoned cultivated fields can increase soil organic carbon, but it is still lower than soils under forest that have never been cultivated.

Summary: Grazing exclusion is a widely implemented strategy for restoring degraded grassland ecosystems and increasing carbon stocks. This study analyzed data from 199 experiments to understand the temporal responses and factors influencing plant and soil carbon stocks following grazing exclusion in different grassland ecosystems. The results showed that plant biomass carbon stocks and soil organic carbon stocks decreased exponentially or rationally with years since enclosure. Grazing exclusion had positive effects on aboveground biomass carbon, but the effects on belowground biomass and soil carbon were influenced by climate, initial carbon levels, and grazing exclusion duration. The response of carbon stocks to grazing exclusion stabilized after approximately 40 years, with soil carbon sequestration showing a lagged pattern compared to plant biomass carbon. The study highlighted the effectiveness of grazing exclusion in regions with low carbon content and non-water limited conditions. However, it might not be an effective measure to increase soil organic carbon stocks in water-limited areas like desert grasslands.
