[Current situation and prospect of elevated atmospheric CO2 effects on soil nematodes].

The elevated atmospheric CO2 can make effects on the ecosystem, these effects will be mediated by the soil fauna. In this paper, we firstly discussed the response of the soil nematodes to the elevated atmospheric CO2 in different soil pattern and in different ecosystems. Some evidences indicate that soil fauna of the detritus food webs appear to show positive, neutral or negative responses to the atmospheric CO2 enrichment across different studies. The research prospect in the future was put forward. This paper can help us understand some ecological processes of farmland ecosystems according to the effect of elevated CO2 on soil nematodes and provide the foundation for managing farmland ecosystems effectively.
