Results of null models describing the representativeness of the species in protected areas: (−) denotes values significantly lower than expected by chance, (+) denotes values significantly higher than expected by chance, and (*) denotes non-significant (p < 0.05) values. IUCN Red List categories for all 28 crocodilian species: CR – Critically Endangered, EN – Endangered, LC – Least Concern, NT – Near Threatened, VU – Vulnerable.
