Extended Data Table 4 Additional model runs to examine the influence of plot-level parameters on tree growth response to phosphorus

From: Pervasive phosphorus limitation of tree species but not communities in tropical forests

  1. a, Model including a plot random effect. b, Model including the effect of stem density. Both models are for trees ≥ 10 mm dbh. Stem density was calculated as the number of stems ≥ 100 mm diameter. P values were not calculated, but t-values < −2 or >2 are generally significant at P > 0.05 for sample sizes >60. Response variable = log(growth); number of observations = 18,970; number of species = 541.
