Leaf carbon and nitrogen isotopes, Toolik Lake, Alaska, 2016
We collected leaf gas exchange measurements during three time periods in the 2016 summer, June 19-24, July 12-23 , and August 11-14. Fully-emerged, healthy (not galled or senesced) leaves were used from the four dominant species, Salix pulchra and Betula nana (deciduous shrubs), Ledum palustre (ever...
