Distribución potencial del cerdo asilvestrado, Sus scrofa (Artiodactyla: Suidae) y el pecarí de collar, Pecari tajacu (Artiodactyla: Tayassuidae) en la región de Laguna de Términos, México
Potential distribution of feral pig, Sus scrofa (Artiodactyla: Suidae) and collared peccary, Pecari tajacu (Artiodactyla: Tayassuidae) in Laguna de Términos region, Mexico. Introduction: The presence of feral pigs (Sus scrofa) in addition to habitat fragmentation at Laguna de Términos, Campeche, could cause changes in the distribution patterns and presence of collared peccaries (Pecari tajacu). 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.
