Summary: This study examines the hydrological changes in the upper Yangtze River Basin (UYRB) and analyzes the future changes in water resources and hydroclimatic extremes. The results show that the mean annual runoff volume in the UYRB will decrease further in the future, and the severity of agricultural droughts will increase. Additionally, there will be more frequent drought-pluvial seesaws and increased design floods at major hydrological stations in the UYRB. These findings highlight the importance of adaptive water resources management to address the elevated risk of water shortage and more frequent and severe hydroclimatic extremes in the UYRB.

Summary: This paper introduces a new method, the Residual Mass Severity Index (RMSI), to quantify water availability and compares it to the Standardized Precipitation Index (SPI). By evaluating these indices under different drought durations across Australia, the effectiveness of these indices in measuring water availability is assessed.

Summary: Climate change and extreme weather events pose serious challenges for water management due to their impacts on water resources availability and water quality. This review assesses the impacts of these events and climate change on river water quality and identifies the key responses and driving mechanisms. The findings show that river water quality generally deteriorates under droughts, heatwaves, rainstorms, floods, and long-term climate change, while improvements or mixed responses are also reported. The driving mechanisms include hydrological alterations, rises in water and soil temperatures, and interactions among hydroclimatic, land use, and human drivers.

Summary: Crataegus laevigata is a shade-tolerant shrub or small tree native to central and northern Europe, traditionally used in herbal medicine and as food. Its fruit is primarily dispersed by birds and it easily hybridizes with other species.

Summary: This article provides a comprehensive overview of the biology of Crataegus monogyna, covering topics such as distribution, habitat, morphology, physiology, phenology, fruiting, herbivores and disease, history, and conservation. The species is native to the British Isles and is of both ornamental and ecological value, playing an important role in providing food and habitat for various insects and birds. Expert knowledge is necessary to distinguish between different Crataegus species due to hybridization and horticultural introductions, which can complicate identification in natural stands.

Summary: This study discusses the historical progression of cataract surgery in the British Isles, starting from possible Roman era couching to the popularity of couching in the 18th century. Cataract extraction began to gain traction in the mid-18th century, despite the ongoing popularity of couching.

Summary: This study investigates the suitability of parametric multivariate extreme value models to correctly represent and estimate the dependence structure of concurrent extremes. The results demonstrate the ability of parametric multivariate models to characterize the complex dependence structure of concurrent extremes.

Summary: This study quantified the dynamics and extremes of water storage in the Chao Phraya River Basin for the first time using GRACE (Follow-On) technology, showing that groundwater storage is the main contributor and hydroclimatic extremes are primarily influenced by variations in monsoon season precipitation.

Summary: Climate change is expected to increase the frequency and intensity of extreme events such as droughts and heavy rainfall. While previous studies have focused on the ecological impacts of individual events, there is a growing recognition that compound extremes, when multiple extreme events occur simultaneously, can have greater effects on ecosystems. This study examines the effects of a deluge during a drought on a semi-arid grassland and finds that the deluge can stimulate ecosystem processes but only partially compensate for the reductions caused by the drought.

Summary: False ring production in Taxodium distichum is indicative of tree response to local environmental conditions, with total tropical cyclone precipitation in July as the best predictor for high false ring years. False ring records can serve as robust proxies for tropical cyclone precipitation and have potential for hydroclimate reconstruction.

Summary: This study examines hydroclimatic extremes and resilience in 54 peninsular catchments from 1988 to 2011 and finds that extreme precipitation and discharge indices demonstrate non-stationary behavior, indicating the substantial influence of global climate modes on extreme events. The random forest model outperforms other models in predicting hydrological resilience, and the majority of catchments exhibit low to moderate resilience. These findings highlight the importance of understanding and managing hydroclimatic risks for accurate climate change impact predictions and effective adaptation strategies.

Summary: The study reveals that the global water cycle primarily occurs between land and ocean, with a seasonal amplitude of 17.0 +/- 0.6 millimeters sea level equivalent. During certain periods, the amplitude can change by as much as 29%.

Summary: This study explores the impact of climate change on future droughts in Germany and highlights the need for adaptation strategies. Despite wetter winters, extended droughts persist, leading to increased water stress in summer and autumn. The findings contribute to regional water resources management and enhance understanding of climate change impacts in German low mountain range regions.
