Thule Leaf Gas Exchange Salix and Dryas 2005
Summary
This dataset includes measurements of Dryas integrifolia and Salix arctica leaf gas exchange made under conditions of saturating light, ambient CO2 and optimum temperature. Also included are leaf C and N concentrations and leaf d15N and d13C. Measurements were made at 5 sites near Thule (Pituffik), Greenland: 3 sites along a south-facing hill slope, the site of a warming x watering experiment and the site of a fertilization experiment. At the experimental sites, measurements were made in control plots, in plots that received the higher of two levels of infrared warming and in plots that were fertilized with 5 g N m-2 yr-1 applied as granular NH4NO3 and 2.5 g P m-2 yr-1 as granular P2O5 beginning in 2004. Coverage is from 20050708- 20050801.
