  1. *** P < 0.001, ** 0.001<P < 0.01, * 0.01<P < 0.05 and NS for P > 0.05. NC indicates variables not considered as explanatory variable.
  2. a Herbaceous species were coded 0 and woody species 1; b Short-lived species (annuals and biannuals) were coded 0, and long-lived species (perennial species) were coded 1; c The mode of pollination was coded 0 for abiotic (wind- or water-dispersed) and 1 for biotic (animal-dispersed)
  3. correlation coefficient of simple regression analyses
  4. multiple regression analyses (stepwise option using all significant variables from the simple regression analyses): ΔR2 represents the gain of R2 (proportion of variation explained by the variables) when the variable is incorporated into the model, "--" indicates that the variable does not enter in the model, after the integration of the most explicative variables.
