Predation by Rattus norvegicus on a native small mammal in an Araucaria araucana forest of Neuquén, Argentina
Few previous studies document Rattus predation as a mechanism of impact on native small mammals. In a mixed Araucaria araucana (Molina) Koch -Nothofagus forest in Parque Nacional Lanín in southwestern Neuquén Province, Argentina, we discovered the remains of long-clawed mice, Chelemys macronyx Thomas, cached in a burrow of Rattus norvegicus Berkenhout. We discuss this evidence of predation in light of Rattus biology and invasion ecology. Predation on native small mammals by invasive rats is easily underestimated or overlooked and deserves more careful attention.
