Produced to perform a statistically rigorous meta-analysis of research results on the response by woody vegetation to increased atmospheric CO2 levels, this multiparameter database of responses was compiled from the published literature and unpublished reports and released as an enhancement to the previously published database, A Comprehensive Database of Woody Vegetation Responses to Elevated Atmospheric CO2 (DB-1018). Eighty-four independent CO2-enrichment studies, covering 65 species and 35 response parameters, met the necessary criteria for inclusion in the database: reporting mean response, sample size, and variance of the response (either as standard deviation or standard error).
Physiological "acclimation" or "downward regulation" of photosynthetic rates, stomatal conductance, dark respiration, and water-use efficiency of plants exposed to elevated CO2 levels can be analyzed. The effects of environmental factors (e.g., nutrient levels, light intensity, temperature), stress treatments (e.g., drought, heat, ozone, ultraviolet-B radiation), and the effects of experimental conditions (e.g., duration of CO2 exposure, pot size, type of CO2 exposure facility) on plant responses to elevated CO2 levels can be also be explored with this database.
