### The CARAIB Dynamic Vegetation Model
Anyway, we preliminary observed that varying the presence threshold in the range of 100-200 g C m\({}^{-2}\) yr\({}^{-1}\) had little impact on the simulated species distributions because NPP sharply decreased below these values, once the climatic conditions are no more suitable. We also chose to maintain the same presence threshold for both PFT- and species-specific morpho-physiological parameters for the sake of comparison. \begin{table}
