Relative Contribution of Biotic and Abiotic Factors to Stemflow Production and Funneling Efficiency Revealed[Oct 10, 2019]

Recently, scientists from Northwest Institute of Eco-Environment and Resources (NIEER) measured the stemflow of nine xerophytic shrubs in nearly nine growing seasons from 2010 to 2018 within a desert area of northern China, accompanying with observing on six biotic variables (shrub morphological attributes) and ten abiotic variables (meteorological conditions).

Scientists Investigate the Transport Mechanism of Fine-particle Pollution during January 2014 in Wuhan, Central China[Oct 09, 2019]

Scientists from Institute of Atmospheric Physics found the sharp increases of PM 2.5 concentrations in Wuhan were often driven by strong northerly winds, while PM 2.5 pollution processes in Beijing mainly resulted from weak southerly winds and stable meteorological conditions.
