Appendix A. Saturation responses of leaf litter breakdown rates (k d^{1}) vs. soluble reactive phosphorus and dissolved inorganic nitrogen.
Table A1. MichaelisMenten model results relating dissolved inorganic nitrogen (DIN; mg L^{1}) and soluble reactive phosphorus (SRP; mg L^{1}) effects on maple (Acer rubrum) and rhododendron (Rhododendron maximum) leaf litter breakdown rates (k d^{1}). K_{m} is the halfsaturation constant of DIN and SRP concentrations whereby the process rate is half of V_{max} (the maximum breakdown rate). Data for R. maximum k vs. DIN are not reported because of poor model fits.
