Predictive performance of models for Sandelia spp., Pseudobarbus ‘Breede’ and Galaxias ‘nebula’. The final number of trees fitted, the null deviance, and cross-validated estimates and standard errors (se) of the predictive deviance, correlation, and area under the receiver operator characteristic curve (AUC) are given for the taxa
