Objective: Modelling of potential distribution to assess the overlap or spatial segregation of both species at Laguna de Términos, Campeche. Methods: Potential distribution models were generated with presence data, anthropic and bioclimatic variables using the maximum entropy algorithm (Maxent). Results: The potential distribution models showed spatial segregation between both species. The presence of feral pigs was positively influenced by palm oil crops (Elaeis guineensis) proximity and seasonal rainfall; the potential distribution of collared peccaries was positively correlated with temperature and canopy coverage. Evidence of feral pigs presence was confirmed in Escárcega, Carmen, Candelaria and Palizada in Campeche state and in Balancán and Jonuta in Tabasco state. Our models predicted potential areas for feral pigs in Pantanos de Centla Biosphere Reserve in Tabasco and in areas near the Guatemalan border. Conclusions: We believe a control plan for feral pigs is needed, not only in Laguna de Términos region, but also in adjacent areas in order to prevent the range extension and displacement of native species such as peccaries in other areas in Southern Mexico. 2019 artículo científico 0034-7744 https://www.redalyc.org/articulo.oa?id=44965908006 https://www.redalyc.org/journal/449/44965908006/ https://www.redalyc.org/journal/449/44965908006/html/ https://www.redalyc.org/journal/449/44965908006/44965908006.epub https://www.redalyc.org/journal/449/44965908006/movil DOI 10.15517/RBT.V67I6.37006 es http://www.redalyc.org/revista.oa?id=449 Revista de Biología Tropical application/pdf Universidad de Costa Rica Revista de Biología Tropical (Costa Rica) Num.6 Vol.67
