This indicates that sclerophyllous vegetation type, which is characterized by low leaf conductance (Centritto et al., 2011b), will respond to future elevated [CO2] significantly more than mesophyllous
plants.RWC, a parameter universally used to detect plantwater status, affected in parallel PRI, leaf conductance and CO2 assimilation (Fig.
& Zucc.) Robyns (Bombacoideae, Malvaceae) is usually a larger tree, found in Cerradao (dense cerrado with almost closed woodland) and Cerrado (closed vegetation dominated by trees and shrubs with herbaceous vegetation between them), but mainly in the edges and sometimes inside mesophyllous
and gallery forests.
It is a typical species of Gallery and Mesophyllous
forests, appearing mainly close to water courses.
Pronounced changes in plant morphology occur at higher elevation in mountains at both the middle and the tropical latitudes, where tall, predominantly mesophyllous
tree species are replaced by crooked, nanophyllous species (Grubb 1974, 1977).
Differences in preburn branch diameters and shrubs intermingling with Adenostoma, particularly the volatile mesophyllous
species at site 2, could account for the discrepancy in canopy vs.
