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.
