Niche dimensionality in Pinus. Phylogenies of Clade 7 (Pinus) showing ancestral state reconstructions of the 11 most important niche dimensions in order of importance (a–k). The bottom right panel shows the same phylogeny with species names. Sub-clades within Pinus with conservative (solid ellipse) and labile (dashed ellipse) niche dimensions are highlighted and discussed in the text (see Results and Discussion). The filled circle on trapezoid and step diagrams beside the trait names, show how the trait relates to the modelled growth or resource acquisition function. For example, (a) is the point at which soil moisture causes a reduction in N uptake, that is, when waterlogging reduces N uptake
