Fig. 2: Validation of the calibrated community model.
From: Linking functional traits and demography to model species-rich communities

a Modeled species relative abundances along the temperature gradient. The dominant species (able to reach a relative abundance of 0.03 in at least one community) are colored according to their functional group (forb in blue, grass in red, legumes in green and shrub in yellow), subdominant species are in gray. b Performance of the community model for each plot across the elevation gradient according to Nagelkerke pseudo R2. Red diamonds indicate the pseudo R2 as predicted by the community model calibrated with the empirical functional traits. Blue triangles indicate the 95% quantile of the distribution of pseudo R2 predicted by the null models. Negative values of the pseudo R2 indicate cases where the likelihood of the model is lower than the likelihood of the hypothesis that all sampled species have equal relative abundance. For each model, pseudo R2 values were calculated at the median of the posterior.
