- Abstract
The abundance and diversity of soil bacterial and fungal communities in a wheat field under elevated atmospheric CO concentrations and increased air temperatures were investigated using qPCR and pyrosequencing. Elevated CO concentrations significantly increased the abundances of bacteria and fungi, and an increase of air temperatures significantly reduced fungal abundance. We found that Proteobacteria, Bacteroidetes, Chloroflexi, and Ascomycota were the most abundant bacterial and fungal phyla in the wheat field soil. Elevated CO concentrations and increased air temperatures had no significant effect on the bacterial alpha diversity, whereas fungal richness was reduced under warming treatments. Moreover, we note that certain bacterial and fungal groups responded differentially to elevated CO concentrations and increased air temperatures, and fungal species were highly sensitive to climatic changes.
