Table 3 Results of phylogenetic regression analysis using the threshold model

From: Seed size evolution and biogeography of Plukenetia (Euphorbiaceae), a pantropical genus with traditionally cultivated oilseed species

Model Coefficient (r) mean Coefficient (r) 95% HPD
Seed size ~ Plant size 0.72 0.39 to 0.95
Seed size ~ Fruit type/dispersal mechanism 0.66 0.24 to 0.95
Seed size ~ Seedling ecology 0.57 0.09 to 0.96
Seed size ~ Biome −0.08 −0.65 to 0.51
Seed size ~ Fire tolerance −0.36 −0.87 to 0.31
