presents almost the same Iberian distribution area of the stoat, the prevalence in the weasel has been more than five times higher than in the stoat (10.8% in front of 2%). Due to the fact that the predator behaviour of those two Carnivores is quite similar, it is probable that this difference is caused by the smaller size of the vital territory and the higher population density of the weasel, and by the selective usage of different preys so as to reduce the interspecific competition (Delattre 1987).
