• Researchers Propose New Hypothesis to Explicate Linkage between Mycorrhizal Types of Trees and Forest Soil Nitrogen Cycling

  Dr. Lin Guigang of the Forestry Ecological Engineering Group of the Institute of Applied Ecology (IAE) of the Chinese Academy of Sciences, together with his colleagues Dr. Wang Xugao, Dr. Zeng Dehui and Dr. Yuan Zuqiang at IAE and Professor Richard P. Phillips at Indiana University, recently investigated the differences in soil nitrogen dynamics between forests dominated by arbuscular mycorrhizal trees and ectomycorrhizal trees at four spatial scales (local, regional, continental and global scales).

• Researchers Quantify Effects of Remnant Tree Abundance on Forest Landscape Recovery

  They found that dispersed location and increased abundance in remnant trees significantly accelerated forest recovery. Location of remnant trees had greater effects on landscape recovery than abundance. However, abundance of remnant trees played a greater role on the recovery the late-successional species.

  How Functional Traits Diversified and Phylogenetically Correlated for Co‐occurring Understory Species in Boreal Forest?

  LIU Bo from Institute of Applied Ecology, Chinese Academy of Sciences, together with his collaborators, utilized phylogenetic comparative analysis to examine how functional traits diversified and phylogenetically correlated for co‐occurring understory species. The researchers measured six functional traits for 37 boreal understory species in the field, including leaf area, leaf carbon content, leaf dry matter content, leaf nitrogen content, plant height, and specific leaf area. They constructed a phylogenetic tree with three loci (rbcL, matK, and trnH-psbA) to perform phylogenetic comparative analyses.

  The Impact of Solar Radiation on Litter C and N Dynamics Depending on Forest Canopy Structure and Phenology

  WANG Qingwei from the Institute of Applied Ecology, Chinese Academy of Sciences (CAS) conducted a large appropriate spectral attenuation experiment, collaborating with a couple of senior ecologists. They calculated the contribution of solar spectral irradiance to C and N dynamics in the understorey and an adjacent gap created by a clear-cut in a temperate deciduous forest.

• Researchers Identify Toxicological Mechanism That Regulates Polystyrene Nanoplastics Induced Apoptosis and Inflammatory Response in Human Alveolar Epithelial Cells

  Nanoplastics are tiny plastic particles that can easily enter human lungs through breathing contaminated air. By damaging alveolar epithelial cells, nanoplastic particles can enter the blood system and may cause a wide range of toxic effects and pulmonary disorders.
