  Researchers Find that Above- and Under-ground Biodiversity Jointly Affects Forest Ecosystem Multifunctionality

  Human caused global change and loss of biodiversity have adverse effects on ecosystem functions, for example, can reduce ecosystem productivity and unbalance nutrient cycling.

  Scientists Disentangle the Ecological Drivers of Decoupled Latitudinal Patterns in Bacterial and Fungal Diversity Gradients

  What determines species diversity remains a big challenge. Despite many studies support a latitudinal diversity gradient for the plants and animals, there are still limited evidence to test whether microbial diversity follow this rule or not. Some studies based on specific region even failed to found a linear relationships between microbial diversity and latitude.

• Researchers Reveal Ecological Mechanisms Affecting Soil Nematode Communities Along Aridity Gradient Across Northern China's Grasslands

  Climate changes such as drought are becoming increasingly serious worldwide and significantly affect structures and functions of terrestrial ecosystems. Drought reduces the abundance and richness of soil biota and has different effects on their different functional groups in grassland ecosystems.

  Researchers Reveal Lignin Protection Mechanism in Forest Soils

  Over the course of forest succession, both components of plant residues and the structure of soil microbial communities play important roles in affecting soil aggregates, and thus the sequestration and stability of soil organic carbon.

  New Discoveries Made by Scientists on Ecophysiology of Declining Shelter Forests in Horqin Sandy Land

  Recently, researchers at the Institute of Applied Ecology Chinese Academy of Sciences (CAS) and their collaborators investigated the patterns of growth decline and the underlying physiology of Pinus sylvestris var. mongolica (Mongolian pine) and Pinus tabulaeformis (Chinese pine) in Horqin Sandy Land (HSL), i.e. a key area of land desertification control where the two studied species are commonly used for afforestation.

  Progress in Seasonal Pattern of δ15N and Source Partitioning of Nitrate in Urban Precipitation of Shenyang

  Atmospheric nitrate (NO3-), a sink of nitric oxides (NOx), is an important nitrogen supply to terrestrial and marine ecosystems through wet and dry deposition. Excess deposited nitrogen can cause series of negative impacts on ecosystems, such as soil acidification, eutrophication of water and so on.
