The literatures on recent advances of VA mycorrhiza study at home and abroad, such as physiology and ecology traits, the relationships between VA mycorrhiza and plant diseases, the connections between VA mycorrhiza and beneficial soil organisms were reviewed.

Feedback mechanisms of soil biota to aboveground biology in terrestrial ecosystems;

In this paper, effects of exotic plant invasions on soil biota and soil nutrient cycling processes are reviewed, and the mechanisms that underlie these impacts are discussed.

Due to the importance of soil biodiversity to the maintenance of ecosystem functions but inadequate study on soil biota in China, a series of articles on soil biota were collectively published in this issue of Biodiversity Science.

The rhizosphere talk is the interactions between root and invading root systems of neighboring plants as well as root and soil-borne organisms including bacterium,fungi and animals in the rhizosphere.

Q_ 10 value(an indicator of temperature sensitivity)of SHR are usually affected by a range of factors such as temperature,water content,respiratory substrate and soil organisms.

With the abundant species and immense biomass, soil organism has significant consequences in soil ecosystem.

They were demonstrated mainly in the following 3 aspects:1)toxicity to certain soil microorganisms and soil fauna; 2)nutrient supply to soil microorganisms and soil fauna;and 3)long-term cumulative impact on soil organism that needs further studies.

Litter decomposition in terrestrial ecosystems,an important process in the global carbon budget,is mainly controlled by climate,litter quality and soil organisms.
