Figure 1. Diurnal courses of average air temperature ( T a ), relative humidity (RH), photosynthetic active
radiation (PAR) and air CO 2 concentration ( C a ).
Figure 2. Diurnal courses of net photosynthesis rate ( P N , A), transpiration rate ( E , B), stomatal
conductance ( g s , C) and intercellular CO 2 concentration ( C i , D), vapor pressure deficit (VPD, E) and
water use efficiency (WUE, F) for three dominant species.
