Summary: This study predicts future streamflow changes in 889 watersheds in the contiguous United States based on projected climate and land use changes. The results show that the random forest model can explain over 85% of the variance in most watersheds. The study also found that relative cumulative moisture surplus, forest coverage, crop land, and urban land are the most important variables affecting the time-varying omega.

Summary: This study quantitatively revealed the impact of climate and underlying surface changes on streamflow changes in 34 main basins in the Loess Plateau. It found that streamflow decreased significantly from 1956 to 2020, with a decrease of 17.19 mm (26.95%) after an abrupt change in 1990. The contributions of precipitation, potential evapotranspiration, and underlying surface change to streamflow change were 26.24%, 2.15%, and 73.01%, respectively, and showed significant spatiotemporal differences. This study further deepens our understanding of the response of streamflow to climate and underlying surface changes in the Loess Plateau and can provide theoretical support for systematic regulation of basin water resources in the future.

Summary: This study used the Budyko framework to explore the impact of precipitation and human activities on streamflow variability in the Lancang River Basin. The results showed that the four parametric Budyko equations performed better in reflecting changes in catchment characteristics, and longer baseline periods yielded more reasonable results in attributing streamflow change. The study also found that human activities dominated the streamflow decrease during the transition and impact periods, while climate change further exacerbated the streamflow decrease in LRB.

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: The sensitivity of streamflow to climate change and permafrost thawing in Siberia remains not well understood. Using the Budyko framework and superposition principles, researchers found that the streamflow of the Ob, Yenisei, and Lena rivers have increased over the past 84 years, with precipitation induced by warming climate being a major contributing factor. However, winter streamflow is particularly sensitive to temperature, with rising temperatures potentially increasing groundwater discharge due to permafrost thawing.

Summary: This study estimated the evolution characteristics of runoff and the underlying surface parameter n in the Kuye River Basin using trend analysis and non-linear regression methods. It also determined the contribution of runoff changes and found that complex human activities were the main reasons for the sharp decrease in runoff. In addition, temperature changes and human activities influenced the underlying surface parameters and ultimately changed the runoff.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
