Summary: Feedbacks between the water and carbon cycles in semi-arid mountain ecosystems can introduce uncertainties into carbon storage projections. This study found that warming reduces carbon storage due to water limitations on growth and enhanced soil respiration, but CO2 fertilization and improved water-use efficiency offset this loss. Additionally, accounting for precipitation gradients and actual water storage is important in modeling carbon-water interactions.

Summary: This study investigates the impacts of extreme drought and delayed monsoon on belowground productivity and biogeochemistry in two adjacent semi-arid grasslands. The results show that extreme drought reduces belowground net primary productivity in one grassland but not in the other, while delayed monsoon reduces belowground productivity in both grasslands. However, extreme drought and delayed monsoon treatments have little effect on soil microbial biomass and soil carbon stocks.

Summary: The hyperuniformity of vegetation Turing patterns is related to water-use efficiency. Near the tipping point, Turing-type ecosystems exhibit significant critical slowing down, indicating non-negligible transient dynamical behavior. Reduced rainfall affects both the resilience of the ecosystem's steady state and the rate of spatial optimization of water-use efficiency in long transient regimes. The degree of hyperuniformity can be used to assess the spatial resilience of ecosystems after disturbances.

Summary: Peru, a megadiverse country, displays a great diversity of ecosystems due to its tropical location, marine currents, and complex relief. Arid and semi-arid ecosystems cover a significant portion of the Peruvian territory and are home to a variety of aquatic macroinvertebrates. Research on aquatic macroinvertebrates in Peru has increased in recent years, focusing on bioindication, biodiversity, taxonomy, and distribution, with rivers being the most intensively studied ecosystems. Further studies are recommended to explore the taxonomic and ecological aspects of macroinvertebrates, especially in the eastern slope, and to calibrate biotic indices for main hydrographic basins.

Summary: Droughts are projected to increase in magnitude, frequency and duration in the near future. This study found that arid and semi-arid rangelands are more severely impacted by drought in terms of forage provision compared to mesic rangelands. The negative impact on forage productivity in these rangelands is mainly driven by the reduction in productivity of key plant species.

Summary: Anthropogenic climate change is causing an increase in climate extremes, which have detrimental effects on biodiversity. However, certain organisms may also benefit from climate extremes. A review of 16 major taxonomic/functional groups reveals that most groups respond negatively to extreme events, with mosses, legumes, trees, and vertebrate predators being the most negatively affected. Additionally, predicting ecological recovery after climate extremes is challenging and requires considering the characteristics of the recovering species, resource availability, and species interactions.

Summary: In this study, the ground-based drought index SPEI was reconstructed using remotely sensed drought factors, and a composite drought index CDIS was established based on climate elements, soil elements, vegetation, and environmental covariate elements. The bias-corrected random forest model outperformed other models in drought monitoring, showing higher prediction accuracy. The method used in this study was effective and could be extended and applied for high-precision drought monitoring at the regional scale.

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.

Summary: This study examines the spatial aggregation changes in dry and wet areas over land, using data from 1949 and 2018. The results show that the global aggregation degree initially increased and then weakened, but the spatial aggregation process between dry and wet patterns was inconsistent. The study also found that the correlation between the affected area and aggregation strengthened with increases in the dry/wet magnitude.

Summary: Regional studies have reported a lengthening of dry spells (DSLs), but the link between DSLs and heatwaves is still unclear on a global scale. This study examines the increase in DSLs during summer over the global continents using precipitation records. The findings show that the average DSL has increased by 0.46 day/decade since the 1970s, along with increased high-pressure anomalies. These findings suggest that precipitation variations associated with changes in DSLs should be considered in attributions of temperature extremes.

Summary: This study investigates the impact of different monsoon types and their combined effect on flood inundation characteristics in the Langcang-Mekong River Basin (LMRB). The results show that the monsoons and their combined effect overall have a positive impact on inundation frequency, depth, and area. The timing of inundation is usually advanced when the Western North Pacific Monsoon (WNPM) or the monsoon combined effect strengthens, but delayed when the Indian summer monsoon (ISM) strengthens.

Summary: This study selected Mainland Southeast Asia as the study area and investigated the changes in tropical cyclone characteristics and associated rainfall. It was found that cyclones originating from the Western North Pacific and the South China Sea had the greatest influence on rainfall in Southeast Asia, while those from the Bay of Bengal had a relatively small impact. Additionally, the total rainfall contributed by cyclones accounted for up to 47% of the annual extreme rainfall amount in Southeast Asia. The study also observed significant decreasing trends in rainfall in the southeast region and increasing trends in the northeast region.
