John S. Kominoski, Amy D. Rosemond, Jonathan P. Benstead, Vladislav Gulis, John C. Maerz, and David W. P. Manning. 2015. Low-to-moderate nitrogen and phosphorus concentrations accelerate microbially driven litter breakdown rates. Ecological Applications 25:856865. http://dx.doi.org/10.1890/14-1113.1

Appendix B. Fungal biomass and microbial respiration data associated with incubated leaf litter.

Table B1. Fungal biomass (Fungi; mg g AFDM-1) and microbial respiration rates (R; mg O2 g AFDM-1 h-1) for maple (Acer rubrum) and rhododendron (Rhododendron maximum) leaf litter at different targeted concentrations of dissolved inorganic nitrogen (DIN; NO3--N + NH4+-N) and soluble reactive phosphorus (SRP), and DIN:SRP (N:P) ratios on days 14 and 59. NA = missing data. Data are not replicated (n = 1).
