The frugivorous diet of the maned wolf, Chrysocyon brachyurus , in Brazil: ecology and conservation.
Abstract
This paper presents a broad study of frugivory and seed dispersal by the maned wolf (Chrysocyon brachyurus), the largest canid (20-26 kg) in South America. The wolf's diet were analysed in 8 localities (all in the cerrado region of south-eastern Brazil) to document its degree of frugivory. Results showed that all populations of maned wolves were highly omnivorous. With exception of Allagoptera campestris, whose seeds were heavily destroyed (87.5% of 522 seeds in faeces), all fruit species consumed by wolves had most seeds unharmed after passing through the wolf's gut (91.7-100% of seeds intact). Although the maned wolf seems to have a short passage time of food through the gut (∼20-30 minutes), this is counterbalanced by its highly cursorial habits. By recording the location of tracks and faeces and by radiotelemetry data, it was recorded that the maned wolf prefers open cerrado. Therefore, only plant species that establish in open cerrado are likely to be effectively dispersed by wolves.

Maned wolves are generalist omnivores; over 500 dietary items have been reported to be consumed by the species, with an average consumption of 50% vegetable material and 50% animal matter.

Wolf's fruit (S. lycocarpum) is reported as the most important item in the diet, and it is generally the most consumed plant.

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.
