Özet:

 

                 
                        Understanding the mechanisms of how 
environmental factors limit species distribution along environmental 
gradients is a central question in ecology. This study aimed to 
understand species acclimation in view of photosynthetic parameters in 
an arid mountainous region. We measured some photosynthetic parameters 
and light and CO2 photosynthesis response curves for all 
plant communities with seven dominant species in 13 sites along an 
elevation gradient in the Qilian Mountains in arid northwestern China. 
The results showed that species in xerothermic environments had low 
maximum rate of carboxylation (Vcmax) (14.5 μmol m-2 s-1) and maximum rate of electron transport (Jmax) (22.7 μmol m-2 s-1), high light compensation points (60.0 μmol m-2 s-1) and light saturation points (1150.7 μmol m-2 s-1), high dark respiration rates (5.3 μmol m-2 s-1), and high maximum photosynthetic rates (Amax) (18.1 μmol
m-2 s-1) compared with species in mesic 
environments. Photosynthesis parameters did not vary with temperature, 
precipitation, and
altitude in different communities dominated by the same species, Picea 
crassifolia. However, some photosynthesis parameters varied with 
temperature, precipitation, and altitude in communities dominated by 
species other than spruce at different elevations. Selected 
photosynthesis parameters could be used to measure species adaptation to
 environmental gradients in arid mountain regions.
