Current situation and prospect of elevated atmospheric CO₂ effects on soil 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 atnospheric 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.
