Appendix A. Mean 15N enrichment of aboveground biomass by harvest and treatment and natural background 15N.
TABLE A1. Mean 15N enrichment of aboveground biomass by harvest and treatment (mean δ15N in ‰±SE, n = 96 populations for each mean). Natural background (BG) δ15N is given as well (n = 8 for harvests 1 and 2, and n = 7 at harvest 3).
