Anthropogenic aerosols could alter multiple meteorological processes such as radiation regime and air temperature, thereby modifying plant transpiration. However, the lack of field observations at leaf and plant level hinders our ability to understand how aerosols could affect plant water use....

As climate change accelerates, extreme weather events become more severe and frequent. We analyzed the datasets of decade-long observation (2005-2020) of mercury (Hg) stored in two subtropical evergreen forests to understand the impacts of extreme weather on the sequestration of atmospheric Hg in...

In this study, a typical apple-soybean intercropping system was used to analyze the effects of different soil water and heat regulation modes on the spatial distribution of the soil water content (SWC), photosynthetic physiological characteristics, and growth. Three maximum irrigation levels [50%...

Aims: Two-year-old seedlings of Phoebe zhennan were used in this study to explore the responses of osmotic adjustment and active oxygen metabolism to drought stress and the mitigation effect of nitrogen application. Methods: The soil water content was firstly adjusted to four treatment levels, i.e. ...

Background: CCCH-type zinc finger proteins play important roles in plant development and biotic/abiotic stress responses. Wintersweet (Chimonanthus praecox) is a popular ornamental plant with strong resistance to various stresses, which is a good material for exploring gene resource for stress...

Leaf wetness provides a wide range of benefits not only to leaves, but also to ecosystems and communities. It regulates canopy eco-hydrological processes and drives spatial differences in hydrological flux. In spite of these functions, little remains known about the spatial distribution of leaf...

Objective: Quercus variabilis is one of the dominant tree species in Beijing mountainous area. To explore the water use strategies, sap flow characteristics and their relationships of Q. variabilis could provide a theoretical reference for the study of water sorption process of trees, and enhance...

The growth and physiological effects of either decreased precipitation (e.g., drought) or increased one (e.g., flooding) on trees have been extensively studied. However, less attention has been paid to the questions of whether and how trees respond to changes in precipitation regime with different...

As one of the main afforestation species, Pinus tabulaeformis is an important carbon sink in China. We developed tree-ring chronologies of Pinus tabulaeformis at five plantation sites (Lingkong Mountain (LKM), Fujia (FJ), Heishui (HS), Caijiachuan (CJC) and Jiufeng (JF)), and measured the δ¹³C...

Aerosols alter plant photosynthesis and ecosystem carbon uptake through radiative effects. These effects inevitably change plant transpiration and ecosystem water use as CO₂ and water exchange couple through leaf stomatal conductance. However, because of lacking field observations, we know poorly...
