• Nitrogen Enrichment Reduced Aboveground Stability but not Belowground Stability

  A research group leading by Prof. Xiao-Tao Lü, from the Institute of Applied Ecology, Chinese Academy of Sciences, conducted a N addition manipulation experiment in the Erguna Forest-Steppe Ecotone Research Station, Inner Mongolia. They explored the impacts of N addition on the temporal stability of ANPP, BNPP, and NPP and their associated mechanisms at two different spatial scales.

  Researchers Quantify Retention of Deposited Ammonium and Nitrate and Its Impact on Global Forest Carbon Sink

  To address the problems outlined above, Prof. Yunting Fang’s laboratory at the Institute of Applied Ecology, Chinese Academy of Sciences (CAS), initiated a Chinese forest ecosystem 15N tracer network. Based on the results in nine ecosystem-scale paired 15N-tracer experiments from China and four earlier studies in temperate forests in the US and Europe, Prof Fang’s laboratory and Prof Peng’s laboratory (from Peking University) have led an investigation on the fate of atmospheric N deposited ammonium and nitrate into forests and their contribution to forest C sinks.

• Evolutions of Distribution and Driving Factors of Coastal Wetland in Bohai Bay, China.

  A research team from the Institute of Applied Ecology, Chinese Academy of Sciences recently obtained the annual distribution of Suaeda salsa (S. salsa) using RS data in past 30 years in Bohai Bay, China. And the influencing factors of S. salsa changes were analyzed. Furthermore, taking Liao River Delta estuary wetland as an example, the changes of land use before and after the utilization of wetland and the driving factors of ecological environment impacts were analyzed.

  Frequent Stover Mulching Builds Healthy Soil through Soil Bacterial Community

  Soil health, which refers to a soil’s capacity to function as a vital living system according to its potential and changes over time, is the foundation of productive, sustainable agriculture. Although conservation tillage, such as no-till and retention of crop residues, has been widely performed in global agricultural ecosystems to maintain soil health at a satisfactory state. However, it is unclear how the quantity and frequency of residue retention influences soil ecosystem and it remains elusive what the underlying mechanisms are that associated with the soil microbiomes.

• Tree Growth Response to Soil nutrients and Neighborhood Crowding Varies between Mycorrhizal Types

  Tree growth is an important part of forest dynamics, and revealing its driving factors is the basis for predicting forest community dynamics. During the growth and development of plants, the symbiosis between trees and mycorrhizal fungi (e.g. arbuscular mycorrhizal (AM), ectomycorrhizal (EM) and dual-mycorrhizal (AEM)) can improve species ability to absorb nutrients and adapt to the local environment, which ultimately results in the difference of species response to biotic and abiotic factors. However, it remains unclear how species with different mycorrhizal associations exhibit growth responses to local abiotic and biotic gradients.

• Removal of Roots Has Greater Impacts on Forest Soil Microbial Biomass than Removal of Aboveground Litter

  Environmental changes and human activities may change above- and underground litter inputs to the soil, which can regulate the sequestration and storage of soil organic carbon by changing community composition and activity of soil microbes in forest ecosystems.A number of studies have examined the impacts of removing forest litter on soil microbes. However, the results of these studies are quite variable, which greatly limits their potential to predict soil organic carbon dynamics.
