Foliar water uptake in arid ecosystems: seasonal variability and ecophysiological consequences
Rooting depth Cell wall elasticity Leaf water potential Transpiration Rain pulse Dew formation
2024/1/12
Foliar water uptake (FWU) has been reported for different species across several ecosystems types. However, little attention has been given to arid ecosystems, where FWU during dew formation or small ...
Patterns and Internal Stability of Carbon, Nitrogen, and Phosphorus in Soils and Soil Microbial Biomass in Terrestrial Ecosystems in China: A Data Synthesis
spatial pattern C:N:P vegetation types nutrient limitation homeostasis
2023/12/11
Inspired by the strict constraint ratio (relatively low variability) between carbon (C), nitrogen (N), and phosphorus (P) in global soils and soil microbial biomass, our study explores the biogeograph...
Assessment of Drought Impact on Net Primary Productivity in the Terrestrial Ecosystems of Mongolia from 2003 to 2018

2023/11/22
The decomposition of abnormal litter caused by extreme weather events might play an increasingly important role in carbon and nutrient cycling in forest ecosystems under climate change scenarios, whic...
Soil Property, Rather than Climate, Controls Subsoil Carbon Turnover Time in Forest Ecosystems across China
C turnover time SOC stock soil property climate
2023/11/22
Subsoil (0.2–1 m) organic carbon (C) accounts for the majority of soil organic carbon (SOC), and SOC turnover time (τ, year) is an important index of soil C stability and sequestration capacity. Howev...

2017农业生态系统与环境国际研讨会（International Workshop on Agro-Ecosystems and Environment）
2017 农业生态系统与环境 国际研讨会
2017/2/15
气候变暖、土壤侵蚀污染退化和水体污染是威胁人类可持续生存最重要的全球环境问题。为了满足人口增长对粮食和蛋奶肉的需求，高强度的集约化农业生产与不合理的农业土地利用管理，导致水土污染和农业生态系统功能退化，严重威胁人类的生存环境。如何提升农业生态系统的功能与改善人类生存的自然环境质量，需要深刻理解农业生产活动是如何影响自然环境，评价变化的环境对农业生态系统的效应。该研讨会邀请国际SCI刊物《农业，生态...
