Description: Atmospheric CO2 and O30 concentrations are increasing due to human activity and both trace gases have the potential to alter C cycling in forest ecosystems. Because soil microorganisms depend on plant litter as a source of energy for metabolism, changes in the amount or the biochemistry of plant litter produced under elevated CO2 and O3 could alter microbial community function and composition. Previously, we have observed that elevated CO2 increased the microbial metabolism of cellulose and chitin, whereas elevated O3 dampened this response. We hypothesized that this change in metabolism under CO2 and O3 enrichment would be accompanied by a concomitant change in fungal community composition. We tested our hypothesis at the free-air CO2 and O3 enrichment (FACE) experiment at Rhinelander, Wisconsin, in which Populus tremuloides, Betula papyrifera, and Acer saccharum were grown under factorial CO2 and O3 treatments.
Keywords: free-air CO2 and O3 enrichment, extracellular enzymes, polymerase chain reaction-denaturing gradient gel electrophoresis, soil microbial community, fungal metabolism
