Variable contribution of models without and with biotic interaction, where: (A): contribution of variables in species distribution suitability without biotic predictor and (B): contribution of variables in species distribution suitability with biotic predictor. Predictor variables represents: bio2 = Mean diurnal range, bio3 = Isothermality, bio8 = Mean temperature of wettest quarter, bio15 = Precipitation seasonality, bio18 = Precipitation of warmest quarter, bio19 = Precipitation of coldest quarter, syagrus = predicted distribution of Syagrus romanzoffiana.
