• Impact of Recurrent Drought on Grassland Productivity is Mediated by Ratio of Grasses to Forbs

  In view of this, Dr. LUO Wentao, associate researcher of the Eco-stoichiometry research group of the Institute of Applied Ecology, Chinese Academy of Sciences, led a study examining grassland natural restoration following two consecutive years of extreme drought manipulation, and explored the carry-over effects of the extreme drought event on plant community structure and function.

• Study Sheds Light on the Specificity of Root Exudate Types on Soil Organic Carbon Decomposition

  Soil organic carbon is critical for climate regulation and ecosystem stability. Its decomposition can be significantly influenced by plant root exudates via the priming effect. However, the understanding of how specific compounds of root exudates influence soil C decomposition via the priming effect is still lacking.

• Scientists Finish a Series of Research Exploring Effects of Secondary Forest Structure Regulation on Rodents-mediated Regeneration of Korean Pine

  The researchers' study showed that direct sowing Korean pine seeds in secondary forests is not an effective strategy for the regeneration of Korean pines when rodents are common seed predators in the forests. The researchers thus recommended forest managers to create large gaps and plant 3-year-old Korean pine seedlings in secondary forests to effectively accelerate the succession of secondary forests to broad-leaved trees/Korean pine mixed forests.

• Annual Temperature and Carbon Availability as Main Factor Controlling the Contribution of Microbial Residues to Soil Organic Carbon in Eastern China's Forests

  An recent investigation led by Researcher Wang Qingkui from the Forest Plantation Ecology Group of the Institute of Applied Ecology of the Chinese Academy of Sciences examined spatial distribution patterns and drivers of soil fungal and bacterial residues along the eastern forest transect in China.

• CAS Scientists Identify Spatial Distribution and Drivers of Air Pollutants in Urban Street Canyons

  Dr. Miao Chunping, special research assistant from the Urban Forest Research Group of the Institute of Applied Ecology (IAE) of the Chinese Academy of Sciences (CAS), Researcher He Xingyuan and Researcher Chen Wei recently conducted a series of studies on atmospheric pollution.

• Disturbance of a Certain Intensity can Accelerate Spatial Shifts in Tree Species Composition and Biomass

  In a recently published study led by Dr. LIANG Yu, a researcher of the Landscape Process Group of the Institute of Applied Ecology (IAE) of the Chinese Academy of Sciences (CAS), the researchers used LANDIS model (a forest landscape model) to simulate the migration dynamics of tree species under different disturbance scenarios, and quantify the changes in the velocity and direction of tree species abundance in response to these disturbance scenarios.

• Acetobacterium wieringae strain Y Responsible for Anaerobic Microbial Degradation of Isoprene

  The Environmental Microbial Ecology Research Team of the Institute of Applied Ecology of the Chinese Academy of Sciences (CAS) has been engaged in the research of biogeochemistry mediated by anaerobic microorganisms. Recently, the research team started to examine the synergistic interaction of carbon reduction and pollution control with the purpose to meet the national strategic needs of carbon peaking and carbon neutrality. In a new paper published by the research team, Researcher YANG Yi and doctoral student JIN Huijuan of the research team used the sediment collected from Xihe River in Shenyang City as inoculum source and established a microcosmic culture system for the anaerobic conversion of isoprene.

• Tree Growth Response to Soil and Neighbors Depends on Size Classes and Canopy Types

  In view of this, Dr. REN Jing, Dr. FANG Shuai, and Dr. WANG Xugao from the Institute of Applied Ecology of the Chinese Academy of Sciences, cooperating with Dr. Claire Fortunel from the Institute de Recherche pour le Développement (IRD), collected tree census data over 15 years for 42 temperate tree species with spatially-explicit soil and neighborhood crowding information in a temperate forest in northeastern China. They employed a hierarchical Bayesian model to quantify the role of soil nutrients and neighborhood crowding in determining the growth of tree species among different size classes and canopy types, and evaluate how functional traits mediate tree growth response to these drivers.

• Light, Conspecific Density and Soil Fungi had differential effects on Seedling Growth of Temperate Tree Species

  Tree regeneration play an important role in affecting community dynamics and future forest structure and functioning. Seedling growth, as the key part of tree regeneration, is strikingly influenced by multiple abiotic and biotic factors, e.g., light availability, conspecific density and soil fungi. However, the interactive effects of these factors on seedling growth are poorly understood.

• Unmanned Aerial Vehicle with Multi-sensors Used to Characterize Vertical Profiles of Urban Air Pollutants

  In a recent study led by Dr. LI Chunlin and Dr. LIU Miao from the Landscape Ecology Research Group of the Institute of Applied Ecology (IAE) of the Chinese Academy of Sciences (CAS), the researchers investigated the vertical characteristics (0 - 120 m) of air pollutant concentrations (SO2, NO2, PM1, PM2.5 and PM10) using an unmanned aerial vehicle (UAV) equipped with sensors along a sampling belt in the built-up area of Shenyang, an old industrial base in China, capital of Liaoning Province and high-end manufacturing base today.
