Diet of the maned wolf, Chrysocyon brachyurus (Mammalia: Canidae), during wet and dry seasons at Ibitipoca State Park, Brazil
Abstract
Analysis of 141 scats of maned wolf Chrysocyon brachyurus collected in a region of upland forest and meadows of south‐eastern Brazil yielded 351 food items in the wet season (60 scats) and 407 in the dry season (81 scats). Scarabaeidae and rodents were the most frequent animal food in both seasons, complemented by birds in the wet season and unidentified mammals in the dry season. Seeds revealed Solanum lycocarpum to be the most frequent plant food in the dry season and an Annonaceae and a Cactaceae the most frequent in the wet season. A total of 33 seed morphospecies were retrieved. Although our results reveal some shared and some divergent trends from dietary studies undertaken in savanna (‘cerrado’) areas, we found a very high frequency of potentially harmful tourists' garbage. This highlights the necessity for better environmental education and confirms that the maned wolf is a generalist and opportunist omnivore.

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.

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.

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.
