Results of the Kruskal–Wallis test comparing the discrimination and classification abilities for threatened species (T), non-threatened and non-ubiquitous species (NtNu), and ubiquitous species (U), as well as for all groups together, of the models based on species records and on expert knowledge. AUC: Area Under the ROC Curve. Sens: Sensitivity. Spe: Specificity. CCR: Correct Classification Rate. Und: Underprediction Rate. Ove: Overprediction Rate
