Diet of the maned wolf, Chrysocyon brachyurus, in central Brazil
Abstract
Analysis of 105 scats of the maned wolf (Chrysocyon brachyurus) collected in central Brazil yielded 304 occurrences of food items of which fruits of Solanum lycocarpum, rodents, and birds accounted for 61.5%. By analysis of minimum number of individual animals, rodents and birds were 75% of a total of 156 prey. On the other hand, fruits of S. lycocarpum and armadillos (Dasypus spp.) were the bulk of the total estimated biomass consumption, yielding 63.7% in a total of 73.5 kg. Rodents were mostly captured during the dry season, while miscellaneous fruits were consumed mostly in the wet season. The consumption of S. lycocarpum fruits and armadillos was aseasonal. Small rodents were taken in about the ranks of abundance in the study area, but S. lycocarpum fruits were actively searched by maned wolves, for its occurrence is limited to secondary savanna. Prey and fruits typical of savanna (‘cerrado’) and grassland (‘campo’) were the bulk of species, occurrences, prey numbers, and biomass consumed. These findings reinforce the importance of conservation of cerrado and campo in central Brazil. Despite maned wolf being a vulnerable species, its feeding habits are opportunistic, and the main reasons for its decline are likely to be habitat destruction and human disturbance.

Most dietary analyses of maned wolves' diet are based on feces, a method most suitable for free-ranging individuals since it is not invasive and fecal material is relatively easy to access.
“Most dietary analyses of maned wolves' diet are based on feces, a method most suitable for free-ranging individuals since it is not invasive and fecal material is relatively easy to access (Dietz 1984;Motta-Junior et al. 1996;;Aragona and Setz 2001).”

Wolf's fruit (S. lycocarpum) is reported as the most important item in the diet, and it is generally the most consumed plant.
“Yet, wolf`s fruit (S. lycocarpum) is reported as the most important item in the diet, and it is generally the most consumed plant (Dietz1984; Motta-Junior et al. 1996;Motta-Junior and Martins 2002;Santos et al. 2003;De Almeida Jácomo et al. 2004).”

The gastrointestinal tract of canids is comparable to that of other Carnivora; it is not very complex and relatively short, with a simple stomach, a small cecum, and an unsacculated colon.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
