In a stomatal frequency analysis of leaf remains of Quercus nigra, Acer rubrum, Myrica cerifera, Ilex cassine, and Osmunda regalis that were preserved in precisely dated peat deposits of north-central Florida, the stomatal index decreased as a response to an atmospheric CO(2) increase from 310 ppmv to 370 ppmv over the past 60 years. The observations indicate that CO(2) responsiveness may occur in different canopy levels of hardwood-swamp vegetation. Apart from common woody plants, long-lived… CONTINUE READING
