Figure 5. Contribution of Tleaf and
Tcrit to thermal safety margins
(TSMcrit-leaf) of four tropical tree species grown under
common environmental conditions. Points represent plant-level averages
of each variable and lines represent linear regressions. In each panel,
Tleaf data are represented by circles for the individual
points and solid lines for the regression, whereas Tcritdata are represented by triangles for the points and a dashed line for
the regression.
