Resumen:
The lesser grison (Galictis cuja), a poorly known mustelid of southern Soutj America, has been described as a catholic feeder living close to water. Consequently, the potential exists for competition with the recently introduced American mink (Mustela vison). Nonetheless, like most ferrets the lesser grison can be a specialized mammal hunter, in wich case it could benefit from introduced mammalian prey (the European hare, Lepus europaeus, and European rabbit, Oryctolagus cuniculus). The diet and trophic position of the lesser grison in Argentinean Patagonia are described in order to discuss the potential effects of introduced mammalian species on grison populations.
