"Angiosperm" represents parameter values used in estimating the dependent variable if the species belongs to that phylogenetic group. "Grasses", "herbs", and "shrubs" represent parameter values used in estimating the dependent variable if the species belongs to that growth form (GF). "D" represents parameter values used in estimating the dependent variable if the species belongs to that phenological group (deciduous). Amass: photosynthetic capacity per unit leaf mass; Nmass: leaf nitrogen concentration per unit mass; Pmass: leaf phosphorous concentration per unit mass.
