      abstract     = {Free-air CO(2) enrichment (FACE) experiments allow study of
                      the effects of elevated [CO(2)] on plants and ecosystems
                      grown under natural conditions without enclosure. Data from
                      120 primary, peer-reviewed articles describing physiology
                      and production in the 12 large-scale FACE experiments
                      (475-600 ppm) were collected and summarized using
                      meta-analytic techniques. The results confirm some results
                      from previous chamber experiments: light-saturated carbon
                      uptake, diurnal C assimilation, growth and above-ground
                      production increased, while specific leaf area and stomatal
                      conductance decreased in elevated [CO(2)]. There were
                      differences in FACE. Trees were more responsive than
                      herbaceous species to elevated [CO(2)]. Grain crop yields
                      increased far less than anticipated from prior enclosure
                      studies. The broad direction of change in photosynthesis and
                      production in elevated [CO(2)] may be similar in FACE and
                      enclosure studies, but there are major quantitative
                      differences: trees were more responsive than other
                      functional types; C(4) species showed little response; and
                      the reduction in plant nitrogen was small and largely
                      accounted for by decreased Rubisco. The results from this
                      review may provide the most plausible estimates of how
                      plants in their native environments and field-grown crops
                      will respond to rising atmospheric [CO(2)]; but even with
                      FACE there are limitations, which are also discussed.},
