The relationships and sensibility of wheat C:N:P stoichiometry and water use efficiency under nitrogen fertilization

open access: yesPlant, Soil and Environment, 2015
A field study was conducted to investigate the variations in the carbon:nitrogen:phosphorus (C:N:P) stoichiometry of winter wheat (Triticum aestivum L.) and its relationships with wheat growth rate (r) and water use efficiency (WUE) under different rates

AMPK‐mediated prevention of vascular dysfunction with metformin: Experimental and population‐based evidence

open access: yesBritish Journal of Pharmacology, EarlyView.
Angiotensin II induces vascular inflammation, senescence, extracellular matrix (ECM) degradation and endothelial dysfunction, thus impairing SK+/IK+ channel function and reducing endothelial‐dependent hyperpolarisation (EDH). Metformin activates AMPK, increasing SK+/IK+ channel function and restoring vasorelaxation.

Food System Change, Development, and Vulnerability in Semi‐Agricultural Areas of Tibet

open access: yesCulture, Agriculture, Food and Environment, EarlyView.
ABSTRACT With social and economic development, food systems have significantly changed on the Tibetan plateau over the last two decades. However, the impact of dietary change on Tibetans and their communities remains less well known. This article examines how food change happens in semi‐agricultural areas of eastern Tibet within the context of ...

Measuring Thematic Funds Performance via an Approach Based on Observable and Latent Factors

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT This paper investigates whether thematic equity funds deliver abnormal performance relative to conventional global equity funds. Using Fama‐French models augmented with latent factors, we estimate fund‐level alphas, and apply the false discovery rate methodology to an estimated three‐group mixture distribution, separating good, null and bad ...

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...

Effects of Rainfall Exclusion Treatment on Photosynthetic Characteristics of Black Locust in the Sub-Humid Region of the Loess Plateau, China

open access: yesPlants
The mesic-origin species Robinia pseudoacacia L. (black locust) is widely planted in the semiarid and sub-humid areas of the Loess Plateau for the reforestation of vegetation-degraded land. Under the scenario of changing precipitation patterns, exploring

Improving water-use efficiency by decreasing stomatal conductance and transpiration rate to maintain higher ear photosynthetic rate in drought-resistant wheat

open access: yesCrop Journal, 2017
In wheat, the ear is one of the main photosynthetic contributors to grain filling under drought stress conditions. In order to determine the relationship between stomatal characteristics and plant drought resistance, photosynthetic and stomatal ...

Environmental influences on the maximum quantum yield of terrestrial primary production

open access: yesNew Phytologist, EarlyView.
Temperature and aridity effects on terrestrial ecosystems' intrinsic quantum yield. Summary Historically, terrestrial biosphere models (TBMs) have assigned the intrinsic (maximum) quantum yield of photosynthesis (ϕ0)$$ {\phi}_0\Big) $$ a constant value for each plant functional type. However, experimental studies have shown that ϕ0$$ {\phi}_0 $$ – when
