A monotypic species and the biggest of South-American canids. The evolutionary lineage that occupied open-vegetation habitats gave origin, among others, to the maned wolf, Chrysocyon brachyurus (Illiger, 1815). The history of occupation of the Neotropical region by these animals started with distinct lineages, according to habitat availability (Mcnab 1989). South-American canids are represented by a diverse group that diversified in the continent during the end of the Pliocene and beginning of the Pleistocene (Berta 1987). ![]() Key words: Chrysocyon brachyurus, diet, maned wolves, RPPN Serra do Caraça. Our findings stress the need for a better understanding of the effects of additional foods on the natural feeding habits of the maned wolf. There was a significant correlation between the availability of small mammals and their consumption by the maned wolves (r s = 0.59 p = 0.041), yet the same was not observed for the fruits of S. lycocarpum (c 2 = 10,09 p < 0,001), for other fruits (c 2 = 19,73 p < 0,001), and for reptiles (c 2 = 15,56 p < 0,001), all of which were more frequently eaten during the dry months. Seasonal variations in consumption were found for S. Food items of anthropic origin and inorganic items (e.g., plastic) represented 14.1% of all occurrences, which shows that the animals are used to the presence of humans. is a common food item in the diet of the maned wolf, its occurrence in the diet at the Serra do Caraça Reserve was insignificant, accounting for only 4.8% of the total number of food item occurrences and 3.4% of the total estimated biomass consumption. Even though the fruit Solanum lycocarpum St.-Hil. Insects, however, had practically no importance (0.1%) in the total estimated biomass consumed. Rodents, insects and birds added up to 35.8% of the occurrences, yet accounted for 68.5% of the total number of preys (277). ![]() A total of 569 occurrences of food items were recorded, of which 56.8% were of animal origin and 29.1% of vegetal origin.
