Experimental investigations on the environmental determination of delta 13C at different altitudes
1990
Morecroft, M.D. | Woodward, F.I.
The influence of environmental variables which are known to change with altitude on the delta 13C of leaves of Nardus stricta, have been investigated in controlled environment experiments. Low temperature and an increased incidence of freezing temperatures caused delta 13C to increase. In contrast, lowered atmospheric pressure reduced delta 13C. Increased leaf surface wetness and soil water content also caused a decrease. Plants from different altitudes did not differ consistently or significantly in their responses.
