Summary: This study investigates the soil water dynamics in the core monsoon zone of India by analyzing the observations of soil moisture. The research reveals that lower soil moisture is associated with depleted convective activity and higher temperatures during the pre-monsoon season, while monsoon rains increase soil moisture. The study highlights the importance of surface-subsurface soil moisture observations in unraveling the complexity of soil water dynamics.

Summary: A thorough understanding of water budget components, specifically evapotranspiration and storage in the watershed, is crucial for effective water resources management and hydrological modeling. This study analyzes 13 years of hydrological data from two agricultural watersheds in Eastern Nebraska, United States to examine various aspects of the water budget, including water-and energy-balance closures, water budget residues, storage in soil layers, and evapotranspiration estimates. Remote-sensing data is also used to assess spatial variability in net radiation and soil moisture. The study finds that adjusting measured evapotranspiration to close the energy budget aligns with water budget estimates, and storage calculations using soil moisture and recession analysis produce the most accurate evapotranspiration estimates.

Summary: This study aimed to investigate the effects of rock fragment coverage on soil erosion and how these effects were influenced by rock fragment sizes. The results showed that total runoff and sediment concentration increased with rock fragment size. However, when the rock fragment sizes were less than 12.0 cm, the total runoff and sediment concentration were lower compared to bare soil. On the other hand, when the rock fragment sizes were larger than 12.0 cm, they increased the total runoff and sediment concentration in the wet run. This study highlights the importance of considering rock fragment size when assessing the effects of rock fragment coverage on soil erosion.

Summary: Soil erosion is a common problem in Durango, Mexico, affecting 77.4% of the territory. The hydrological keyline design (HKD) was found to retain more water and reduce sediment transport compared to the control group, ultimately leading to a 126% increase in bean yield compared to the regional average. The implementation of HKD had a positive impact on soil and moisture conservation.

Summary: This review explores the exchange of goods and services between fungus and phototroph in lichens and how it contributes to the success of both symbionts and their symbiosis. Lichen fungal symbionts have the unique characteristic of exposing most of their mycelium to an aerial environment. Phototrophs provide carbohydrates to the fungus, which are converted into specific polyols with multiple functions, including growth, respiration, and desiccation tolerance. Fungal symbionts provide protection against herbivory and light stress for phototrophs and influence fungal sex and morphogenesis. These interactions create a multiplayer marketplace that drives symbiont selection and lichen diversification.

Summary: Climate change leads to increased temperatures and dry periods in certain parts of Europe, affecting tree growth by decreasing water availability. Pioneer tree species will face limitations in successfully establishing themselves on damaged areas in the future. This study examines how different microsite conditions and reduced water availability affect establishment success and growth of three tree species. The results show that germination and establishment require persistent moist conditions, and seedlings cannot survive without watering for more than 3 weeks. Moss and litter cover can retain soil moisture, but their initial seed germination is lower compared to open soil. Radiation does not affect germination and survival, but it significantly impacts growth, with higher radiation resulting in larger shoot lengths and above ground biomasses. Overall, Betula pendula is the most drought stress resistant species, while Populus tremula and Salix caprea struggle to establish themselves on dry sites, making it even more challenging under climate change. The lack of moist, vegetation-free open soils will lead to a significant reduction in establishment success for pioneer tree species in the future.

Summary: This study investigates the impacts of temperature warming, rainfall reduction, and biocrust cover on soil phosphorus (P) pools in drylands. It finds that warming increases most P pools, except occluded P, while rainfall reduction has no effect on soil P pools. Biocrusts enhance soil P pools and provide resilience against warming and rainfall reduction.

Summary: Biological soil crusts play a significant role in stabilizing the soil surface of drylands. However, quantitative information on their impact on global dust cycling and climate effects is limited. This study reveals that biocrusts reduce global atmospheric dust emissions by approximately 60% and prevent the release of about 0.7 Pg dust per year. However, due to climate change and land-use intensification, the coverage of biocrusts is expected to be severely reduced by 2070, leading to increased dust burden and a reduction in the global radiation budget. These findings emphasize the importance of considering the control of biocrusts on dust cycling and its climate impacts in modeling, mitigation, and management of global change.

Summary: This study aimed to explore the impact of water vapor adsorption by soil in drylands on the water cycle, carbon cycle, and ecosystem processes. Through field observations and statistical modeling, the study found that water vapor adsorption had higher fluxes during hot and dry periods, and exhibited a diel coupling with CO2 fluxes. Additionally, the study found that the specific surface area of soil in early succession stages was related to increased CO2 influx.

Summary: Sewage sludge (SS) is widely used as a soil conditioner due to its high content of organic matter and nutrients. This study found that cyanobacteria growth increased in soil amended with low concentrations of composted SS, while higher SS concentrations decreased cyanobacteria growth. However, SS significantly enhanced soil organic carbon gain and tightly-bound exopolysaccharide content. Cyanobacteria inoculation improved soil stability and had the potential for salt immobilization and soil bioremediation.

Summary: Biocrusts play a crucial role in shaping dryland ecosystems through their ecohydrological effects. In this study, a spatially-explicit process-based ecohydrological model was used to assess how biocrusts influence water fluxes and availability in a dryland landscape, and how climate change-induced shifts in the biocrust community affect landscape hydrology. The results showed that biocrusts increase water availability in the landscape, even in dry years. Well-developed biocrusts protect soil from evaporation and redistribute water towards downhill vegetation, highlighting their importance in water redistribution and plant-available water. However, potential changes in biocrust composition and cover could reduce their ability to act as water sources and sustain dryland vegetation.

Summary: High-resolution climate data is crucial for predicting regional climate and water environment changes. In this study, a two-step downscaling method was developed to enhance the spatial resolution of GCM data and improve the accuracy for small basins. The method combined medium-resolution climate data with high-resolution topographic data to capture spatial and temporal details. The downscaled climate data were then used to simulate the impacts of climate change on hydrology and water quality in a small basin. The results demonstrated the effectiveness of the downscaling method for spatially differentiated simulations.

Summary: Precipitation over the Tibetan Plateau is influenced by systems such as the Asian monsoons, the westerlies, and local circulations. The Indian monsoon, the westerlies, and local circulations are the main systems affecting precipitation over the entire Tibetan Plateau. The East Asian summer monsoon primarily affects the eastern Tibetan Plateau. The Indian monsoon has the greatest influence on precipitation in the southern and central grid cells, while the westerlies have the greatest influence on precipitation in the northern and western grid cells. Local circulations have the strongest influence on the central and eastern grid cells.
