Abstract: The long-term effects of rising atmospheric carbon dioxide (CO2) and tropospheric O3 concentrations on fungal communities in soil are not well understood. Here, we examine fungal community composition and the activities of cellobiohydrolase and N-acetylglucosaminidase (NAG) after 10 years of exposure to 1.5 times ambient levels of CO2 and O3 in aspen and aspen-birch forest ecosystems, and compare these results to earlier studies in the same long-term experiment.
