Summary: To ensure sustainable agricultural management, understanding the soil erosion rates and soil water content under different conditions is vital. This study utilizes cosmic-ray neutron sensors and fallout 137Cs as novel approaches to explore the relationship between soil water content and soil redistribution processes. Results show that the neutron sensors effectively capture soil moisture dynamics and highlight the sensitivity of soil water content to parent material. The study also finds that soil type significantly influences soil moisture spatial variability, impacting soil erosion and sedimentation rates.

Summary: The study examines the alterations in root hydraulics of Phragmites australis under varying soil moisture conditions. The findings show that drought stress leads to a reduction in root diameter, cortex thickness, vessel diameter, and root cross-sectional area. Decreased soil moisture content significantly affects root morphological and anatomical characteristics, thereby altering root hydraulic conductivity. Transcriptome analysis suggests that the expression of abscisic acid and aquaporins genes may be associated with these changes.

Summary: Conifers at the alpine treeline experience dramatic losses of hydraulic conductivity during winter, but are able to recover in late winter. Water is taken up and redistributed within the crown, with melting snow potentially serving as a prime source of absorbed and redistributed water. The extent of water absorption and redistribution varies among species, with L. decidua showing higher rates and bark participating in the process of water absorption.

Summary: In this study, the redistribution of soil water due to hydraulic forces and temperature gradients in dry sandy soil was investigated. The results showed that shrub vegetation strongly influenced the patterns of soil water redistribution through hydraulic redistribution. It was found that plants were able to move water from moist to drier soil areas to enhance nutrient uptake. At the same time, the study also revealed that soil water potential fluctuations in non-vegetated areas were primarily due to variations in soil temperature. The findings highlight the importance of considering biotic factors, such as hydraulic redistribution, when analyzing water balance changes and hydrological niche segregation in desert ecosystems.

Summary: Historical land-use practices have caused significant forest loss and fragmentation in Cambodia's Tonle Sap Lake area. Despite the establishment of protected areas in 2001, forest loss continued until 2010. While net forest loss stopped after 2010, the level of forest regain was insufficient to restore the region's total forest area. More effective planning and implementation of forest management and restoration policies are needed for the area.

Summary: Sorafenib is a first-line agent for advanced liver cancer, but drug resistance affects its efficacy. In this study, we demonstrated that piperlongumine (PL) enhances the cytotoxicity of sorafenib in liver cancer cells by inducing ROS generation, mitochondrial dysfunction, and apoptosis. Activation of the AMPK signaling pathway and disruption of RNA processing are involved in the antitumour activity of PL and sorafenib combination treatment.
