Description

Model selection results from analysis of the relationship between a priori 1- and 2-variable weather models and native, exotic, and total plant species (A) richness and (B) Shannon diversity in each annual nitrogen fertilization treatment at Cedar Creek (1985–2003, N = 19). R² = least square means regression coefficient, K = # of model parameters including intercept and first order autoregressive parameter, LL = log likelihood, AICc = Akaike Information Criterion corrected for small samples size, DAICC = difference in AICc value between given model and model with lowest AICc, wi = Akaike weights (measure of relative importance of a given model compared to all other models in the model set). Treatment (TRT): 0 = true control (no N-fertilizer or micronutrients added), 1 = 0 g·N·m-2·yr-1 + micronutrients, 2 = 1.02 g·N·m-2 yr-1 + micronutrients, 5 = 5.44 g·N·m-2 yr-1 + micronutrients, 8 = 27.2 g N·m-2·yr-1 + micronutrients. CV = coefficient of variation, sum = summer, spr = spring, win = winter, PPT = precipitation, TEMP = temperature, t_1 = season preceding growing season (spring and summer) when plants were sampled. Ecologically meaningful models (EMMs) were those with DAICC < 2 and R² > 0.30. Model # corresponds to a priori models as described in Appendix B.
