• Researchers Find New Geobacter sp. Strain That Dihaloeliminates Organochlorine Pollutants

  Prof. Yang Yi, Prof. Yan Jun and doctoral student Jiang Lisi of the Institute of Applied Ecology of the Chinese Academy of Sciences recently finished a study exploring environment-friendly agents for the biodegradation of chlorinated pollutants. They collected polluted river sediments and established a 1,2-dichloroethane and 1,1,2-trichloroethane (1,2-DCA and 1,1,2-TCA) enrichment culture system.

• Hydraulic Vulnerability Segmentation Mechanism Helps Compound-leaved Tree Species Withstand Drought Stress

  Compound-leaved tree species usually have higher productivity compared with simple-leaved species. That is because trees with compound-leaves generally have higher water transfer efficiency, and thus higher potential rate of photosynthetic carbon assimilation. This finding had been revealed in a research led by Prof. HAO Guangyou of the Plant Physiology and Ecology Group at the Institute of Applied Ecology of the Chinese Academy of Sciences.

• Xylem Hydraulics Mediates Radial Growth Response of Trees to Climate Warming

  The researchers extracted tree-ring information and quantified xylem hydraulics characteristics of Larix olgensis and Pinus koraiensis, two major tree species in Northeast China, along an altitude gradient ranging from 780 m to 1300 m on the North slope of Changbai Mountain.

• Researchers Uncover Physiological Mechanism Mediating Trade-off Between Temperate Tree Growth and Hydraulic Resilience Against Freezing

  The researchers investigated the degree of xylem embolism, the NSC content, and the growth rates of fifteen tree species from the genus Acer (maples), Betula (birches) and Populus (poplars) in the Korean pine and broad-leaved trees mixed forests in Changbai Mountain Area.

• 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.
