Fig. 1. Plant traits (seed mass, plant height, leaf area,
genome size, leaf N, and growth form) mapped onto a plant phylogeny.
Note that data were log 10-transformed prior to mapping.
Fig. 2. Tests of phylogenetic signal in plant traits. A
statistically significant phylogenetic signal was detected in seed mass
(a, λ = 0.976, P < 0.001), plant height (b, λ = 0.964, P
< 0.001), genome size (d, λ = 0.956, P < 0.001),
leaf area (c, λ = 0.883, P < 0.001), leaf N (e, λ = 0.771, P
< 0.001), and growth form (f, D = -0.148,
Prandom = 0, PBrownian = 0.982) of 1071
plant species.
Fig. 3. Comparison of seed mass, plant height, leaf area,
genome size and leaf N between plant species with different growth forms
(woody vs non-woody) derived from general linear model (GLM).
Fig. 4. The relative contribution of different factors to the
variation in seed mass using partial R2s for the
logistic regression model.
