Digital painting on canvas of a jaguar (Panthera onca) from Ejido Caoba (Quintana Roo, Mexico). The paper of Martínez-Gutiérrez et al. indicates that a substantial amount of published diet studies could be seriously biased due to misleading predator identification methods from field samples. Therefore, trophic ecology studies should carefully consider the reliability of the method used in order to gather accurate and useful results for the management and conservation of mammalian carnivores. Photo and painting by Francisco Palomares Fernández, 2010.
