Ellen J. Stuart-Haëntjens, Peter S. Curtis, Robert T. Fahey, Christoph S. Vogel, and Christopher M. Gough. 2015. Net primary production of a temperate deciduous forest exhibits a threshold response to increasing disturbance severity. Ecology 96:2478–2487. http://dx.doi.org/10.1890/14-1810.1

Appendix A. Aboveground wood net primary production (ANPPw) and litter trap leaf area index (LAIt) for all plots prior to and following peak disturbance, the fraction of tree basal area girdled in each plot, and the three most dominant upper canopy tree species with respect to basal area in each plot prior to disturbance.

Table A1. Aboveground wood net primary production (ANPPw) and litter trap leaf area index (LAIt) for all plots prior to and following peak disturbance, the fraction of tree basal area girdled in each plot, and the three most dominant upper canopy tree species with respect to basal area in each plot prior to disturbance. Plots and data in bold indicate the 10 plots selected for analysis of fAPAR, percent foliar N, photosynthetic capacity, and canopy openness.
