  1. Phylogenetic signal in the 11 key niche traits based on a conifer phylogeny covering 455 species and estimated using Pagel’s λ and Blomberg’s K. The p-value (P) for λ is estimated using the likelihood ratio test. The p-value for K is estimated from a randomization test based on 1000 simulations of the data. The numbers in parentheses indicate the position of the specific trait in the growth or resource acquisition function. For example Soil moist N uptake (3), is the point at which increasing soil moisture, starts to limit nitrogen (N) uptake, i.e. when water logging limits N uptake.
