Description: We investigated the interactive effects of elevated concentrations of carbon dioxide ([CO2]) and ozone ([O3]) on radial growth, wood chemistry and structure of five 5-year-old trembling aspen (Populus tremuloides Michx.) clones and the wood chemistry of paper birch (Betula papyrifera Marsh.). Material for the study was collected from the Aspen FACE (free-air CO2 enrichment) experiment in Rhinelander, WI, where the saplings had been exposed to four treatments: control, elevated [CO2] (560 ppm), elevated [O3] (1.5 x ambient) and their combination for five growing seasons.Wood properties of both species were altered in response to exposure to the treatments.

Keywords: Betula papyrifera, carbon dioxide, cell wall, climate change, FACE, ozone, Populus tremuloides, wood chemistry, wood structure
