Abstract Successful use of stable isotopes (δ2H and δ18O) in ecohydrological studies relies on the accurate extraction of unfractionated water from different types of soil samples. Cryogenic vacuum distillation (CVD) is a common laboratory‐based technique used for soil water extraction; however, the reliability of this technique in reflecting soil ...

Abstract As ecological data and associated analyses become more widely available, synthesizing results for effective communication with stakeholders is essential. In the case of wildlife corridors, managers in human‐dominated landscapes need to identify both the locations of corridors and multiple stakeholders for effective oversight.

Abstract The COVID‐19 pandemic has forced the confinement of most populations worldwide, through stay‐at‐home orders. Children have continued their education process at home, supervised by parents, who, in most cases, have adopted the role of prime drivers of their learning processes. In this study, the psychological impact of confinement was explored,

Highlights Three identified clusters based on seven commonly measured serum electrolytes had different metabolic profiles, associated with distinct risk of developing diabetes and progression of glucose and lipid metabolic traits. Individuals in Cluster A were older, more were women, and had “normal” to low risk for diabetes.

该文以ys 930超空化水翼和NACA 65410水翼作为研究对象,采用RNG k-ε湍流模型、Zwart-Gerber-Belamri空化模型以及动网格技术,对比两种翼型在俯仰、升沉以及俯仰升沉复合运动情况下的水动力性能。结果表明:运动幅值的增加会使得升力系数和阻力系数曲线峰值明显提高;水翼在俯仰和复合运动情况下的升力系数和阻力系数会产生明显的尖峰,而尖峰主要是由下翼面气泡溃灭造成的。为进一步研究两种翼型的水动力性能,将升力系数和阻力系数的平均值和方差进行对比分析。结果表明 ...

土壤水力参数是土壤水分和污染物迁移等陆面过程数值模拟的重要基础参数。为探明关中平原农田土壤水力参数空间分异特征,建立空间分布预测模型,在关中平原网格布设124个样点,采集根层0-20 cm原状和扰动土壤样品,利用van Genuchten模型拟合获取土壤水分特征曲线,获得残余含水量(θr)、饱和含水量(θs)以及系数α和n等土壤水力参数。采用经典统计学、地统计学和结构方程方法分析了θr、θs、α和n的空间变异特征及影响因子,建立了水力参数传递函数预测模型。结果表明:θr和α为强变异,θs为中等变异 ...

ABSTRACT Water governance has emerged as a critical analytical framework for addressing the complexity of socioecological water systems in contexts of increasing climate vulnerability and anthropogenic pressure. This study presents a systematic review and bibliometric analysis of 50 scientific articles indexed on water governance published between 2018

This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...
