Table 1 Taxon-specific PnET-Succession parameters. Tuned parameters indicated by *. Red maple and red oak were parameterized based on Coulston et al. 2003 because they were not included in the Aspen-FACE experiment

From: Extrapolating plot-scale CO2 and ozone enrichment experimental results to novel conditions and scales using mechanistic modeling
