Resumen:
According to central place foraging theory, adult Patagonian gray foxes (Pseudalopex griseus) baheving efficiently should consume on the spot those food items too large to be carried and those too small to warrnt being carried to the den. Consequently, fox cubs should be provisioned with intermediate-sized items. We tested this prediction by analyzing 96 fecal samples from adult foxes and 82 fecal samples from cubs belonging to three different dens collected near Junín de los Andes in the province of Neuquén, Argentina, from November 1994 to January 1995.
