  Researchers Reveal the Important Role of Seed Orchards in Protecting the Genetic Diversity of Pinus Koraiensis

  Ex situ conservation is an important strategy for biodiversity conservation, in particular intraspecific genetic diversity. Genetic diversity represents the basis for evolutionary adaptation and resilience to environmental stress and change.

  How Nitrogen Deposition Affects Community Litter Nutrient Status

  Litter nutrient status plays an important role in driving litter decomposition and ecosystem nutrient cycling. Nitrogen (N) deposition could alter community-level litter nutrient status through both intra- and inter-specific pathways, but their relative importance remains unknown.

• IAE Scientists Reveal the Role of Rhizosphere in Mediating Phytoremediation Effects on PAHs-Cd Contaminated Soil

  The polycyclic aromatic hydrocarbons (PAHs) is a widespread environmental pollutant that seriously threats soil health, human life and ecosystems.

  Researchers Quantify Ecosystem-scale Nitrification Rate

  Human-caused dramatical increase in gaseous nitrogen (N) emissions to the atmosphere has accelerated terrestrial ecosystem N deposition over the past half century.

  Researchers Reveal How Amount and Frequency of Stover Mulching Regulate Decomposition Pathways of Soil Micro-foodwebs

  The input of exogenous organic carbon is an important factor affecting soil organic carbon (SOC) dynamics in farmland. It improves the level of SOC and is a major carbon source for soil biota. Returning straw (stover) to soil is one of the major measures adopted worldwide to enhance soil fertility.

  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.
