Leaf tissue was dried in an oven for 3 days at 65°C and then ground in individual 2 ml tubes containing one 0.3 cm metal bead using a TissueLyser (Qiagen, Hilden, Germany). Three to five mg of ground tissue were packed in tin cups and sent for inorganic element analysis to the Pacific Centre for Isotopic and Geochemical Research of the University of British Columbia
