Variables included in the model were region in which the species is found (Africa, Asia, Madagascar, The Americas), whether the species was affected by any of the 12 IUCN Level 1 threat types (Yes/No), the number of countries in which the species was found, and the number of Level 1 threats described for the species. Italics indicate significant results.
