Summary: This study attempts to reconstruct the precipitation in the Ejina Oasis in the lower reaches of the Heihe River using the stable oxygen isotope ratio. The findings suggest that the oasis has suffered from severe drought in the past decade, and human activities have contributed to a decrease in air moisture. Practical measures are recommended to mitigate water stress on the oasis.

Summary: The recent discovery of complete ammonia oxidizers (comammox) challenges the traditional understanding of nitrification, showing that one organism can convert ammonia to nitrate. This study on nitrifying microorganisms in the Nanliu estuary demonstrates the niche specificity of different nitrifiers modulated mainly by salinity. The research also reveals a clear response by comammox Nitrospira to a wide range of simulated salinity levels.

Summary: This study analyzed the changes in species composition and diversity within successional gradients in arid and semi-arid areas of China. The results showed differences in species composition and life forms between different successional stages, while species richness was lower in late-successional stages. The study also found that alpha-diversity reached its peak in the middle of the succession, and species turnover occurred during succession.

Summary: The changes in soil microbial characteristics following vegetation succession in coastal tidal flats are poorly understood. Understanding the soil microbial change pattern can help us better manage tidal flat ecosystems. The study found that the bacterial and AMF diversity and richness increased in vegetation-covered soil, while the salt ion contents decreased as vegetation succession occurred. The microbial network structure was more complex in the late succession stages. Salinity is the key factor driving shifts in soil microbial community composition and network complexity during coastal vegetation succession.

Summary: This study revealed significant shifts in both autotrophic abundance and community structure during biocrust succession, highlighting the combined effects of soil factors on autotrophic community variation. The abundance of cyanobacteria and algae was mainly influenced by soil water, organic carbon, total phosphorous, available potassium content, and pH, while the abundance of prokaryotic non-cyanobacterial autotrophs was mainly influenced by soil water content. Variation partitioning analysis showed that variation in community structure was related to soil nutrients, ion content, and physical soil properties.

Summary: Fencing is an economical method for restoring degraded desert ecosystems and plays a crucial role in promoting plant community diversity and productivity, as well as ecosystem structure and function. This study found that after 10 years of fencing restoration in a degraded desert plant community, species diversity significantly increased, especially in the herb layer. The changes in community diversity were influenced by the nursing effects of the shrub layer and soil physical and chemical properties.

Summary: The study found that the application of water-saving irrigation techniques and increased total precipitation altered water exchange fluxes and groundwater dynamics, significantly reducing spatial heterogeneity in soil moisture in oasis fields. Water-saving irrigation, in conjunction with restrictions on land reclamation and adjustments in water management practices, is the most effective way to maintain the coexistence of oasis and desert ecosystems in arid inland regions.

Summary: This study investigated the distribution of textural layered soils in the desert-oasis ecotones in northwestern China, and analyzed the effects of different soil-textural configurations on water regimes. The results showed that the thickness of a medium-textured layer had a significant positive correlation with soil water content, while burial depth had minimal effects on water retention properties.

Summary: In salt-affected and groundwater-fed oasis-desert systems, the balance of water and salt is crucial for stable coexistence of ecosystems. An investigation on the spatio-temporal variability of soil salinity and groundwater dynamics reveals accelerated soil salinization in water-saving agricultural lands, leading to a worsening regional water-salt imbalance. The continuous decline in groundwater tables, dramatic shifts in flow patterns, and degradation of groundwater quality are exacerbating the situation.

Summary: The study found that the water uptake characteristics of Populus euphratica and Tamarix chinensis varied at different growth stages, with deeper soil water being the main water source for T. chinensis. Water use efficiency was higher for both species without river water, but T. chinensis showed a greater dependence on groundwater. This highlights the importance of considering vegetation types and growth stages in ecological restoration management to enhance effectiveness of vegetation restoration strategies.

Summary: This study analyzes the species composition and community structure of a subtropical secondary evergreen broad-leaved forest in Wuchaoshan National Forest Park in Hangzhou, Eastern China. The findings reveal that the forest is in the middle and late stages of succession, and different species have different habitat preferences and distribution areas. Long-term community monitoring is important for indicating the direction and potential of secondary forest succession.

Summary: The study found that alpha(c) in the Loess Plateau exhibits spatial and temporal variability, primarily influenced by aridity index (AI) and average Normalized Difference Vegetation Index (NDVI) during the growing season. The quantified impacts of climate change (mainly expressed by an increase in precipitation) and revegetation (quantified by the NDVI increase) showed that climate change contributes the most to the ET increase (approximately 68% on average), while revegetation also plays a significant role (approximately 32% on average), highlighting the importance of managing water consumption by evapotranspiration in sustainable development.

Summary: Long-term droughts in southern Australia have changed the relationship between annual rainfall and runoff, challenging traditional rainfall-runoff models. The modified GR7J model outperformed the original GR4J model during drought periods, particularly at low flows. The use of an objective function combining daily and annual errors improved the goodness of fit and reduced evaluation bias for the GR7J model.

Summary: Climate warming in the Tibetan Plateau has led to changes in temperature, wind, and rainfall patterns in Southeast Asia, causing significant environmental impacts in the lower reach of the Mekong River basin. Saltwater intrusion has become a major issue in the densely populated Mekong Delta in southern Vietnam, posing threats to freshwater supply and ecosystem degradation. Addressing these challenges requires further research on hydrogeological information, groundwater monitoring, modeling, and identification of effective engineering techniques.

Summary: The study reveals that global land use and land cover changes have a significant impact on water cycles, with woodland cover change being the most sensitive factor affecting water yield. It suggests that the increase in global woodland coverage over the past three decades has led to a notable positive increase in global land evapotranspiration, contrary to previous findings based on potential land cover maps.

Summary: This study evaluated the performance of land surface models in estimating the impact of land-use change on terrestrial evapotranspiration globally. Results showed that errors in simulating land-use change impacts on evapotranspiration stem largely from how land-use data is interpreted. It was found that interpreting land-use data accounted for a larger percentage of errors compared to the model structure itself.
