Understanding the variability in soil hydraulic conductivity in the mountainous headwaters is critical to the modeling of mountainous runoff and the water resources management of river basins, especially in the arid and semiarid areas. In this study, a total of 32 soil profiles with five layers within 0–70 cm were sampled under different land cover types: forest, meadow, high coverage grassland (HCG), medium coverage grassland (MCG), and barren land in the upper stream of the Heihe river watershed, Northwest China. Saturated hydraulic conductivity (KS) was measured for each sample. The vertical variation of KS and soil hydrological response under different land covers were analyzed. Results show that KS value in layer 5 was significantly lower than the values of above four layers. KS decreased in the order of forest, meadow, HCG, MCG, and barren land, corresponding to the degree of vegetation degradation. The KS decreased with depth under forest, HCG, and barren land, but increased first and then decreased under meadow and MCG. The dominant stormflow paths for different land covers were different: forest was dominated by deep percolation, HCG was dominated by subsurface flow (SSF), meadow was prevailed by Hortonian overland flow and had no SSF, while MCG and barren land were also dominated by Hortonian overland flow, but still formed SSF. This result provides important information for improving the accuracy of mountainous hydrological modeling and, in turn, leading to sustainable management of water resources in the study watershed.

Globally shaded leaves contribute to more than a half of the total increase in gross primary production (GPP; 7.6 Pg C) for 1982–2016. During 1982–2016, the fraction of shaded GPP increases by 1.1% (p < 0.01) in tropical forests and decreases by 1.4% (p < 0.01) and 1.8% (p < 0.01) in evergreen needleleaf and deciduous needleleaf boreal forests, respectively, suggesting an ecological niche of certain canopy structure for ecosystems to achieve maximum GPP. Unlike transpiration from sunlit leaves that has a turning point in the trend in 2003, global transpiration from shaded leaves steadily increased at the rate of 34 km3/year (p < 0.0001) during 1982–2016. Our study therefore suggests that shaded leaves have an increasing role in buffering the adverse impact of climate change and extremes. Further studies are still needed to reduce the uncertainties in reported trends arisen from climate forcing data, leaf area index, and land cover and land change products.

Aims To explore the role of self‐efficacy (SE) in the effect of patient empowerment on self‐management behaviours among patients with chronic illness and to investigate the moderating effect of three types of health locus of control (HLC) in this moderated mediation model. Design Cross‐sectional design. Methods Data were collected in a general tertiary hospital, and a sample of 254 patients was recruited between August and October 2020. The effect of moderation and mediation was tested by the PROCESS macro (Model 4 and Model 8) for SPSS 25.0 by Hayes using 5000 bootstrap samples. Results Self‐efficacy significantly mediated the relationship between patient empowerment and self‐management behaviour with a 95% confidence interval excluding zero. The chance HLC demonstrated a moderating effect, and the interaction effect on SE and self‐management behaviour was significant. Conclusion Patient empowerment may improve confidence and adherence to self‐management among people with chronic illness, and such benefits were conditional on the HLC of patients. Impact This study addresses the relationship between patient empowerment and self‐management behaviour in patients with different personality characteristics. This result indicated that classifying the type of HLC may enable the identification of subgroups of patients who may subsequently benefit from patient empowerment. In a patient‐centred programme, nurses and other healthcare professionals correctly identifying patients’ HLC type and understanding the implications and then providing appropriate health care plans for patients with different health beliefs may be useful to tailor the decision‐making process.
