Abstract:
The maned wolf has been studied in nature reserves, but few researches have been carried out outside protected areas. Since only about 2 % of the Brazilian Cerrado, the maned wolf's main habitat, has been set aside as parks and reserves, determining what is happening with the species in private and disturbed areas is important for an accurate assessment of its vulnerability to extinction. Here we investigated the trophic ecology of a maned wolf population inhabiting a 1610 ha section of the Calçada Ridge, an unprotected area located in the metropolitan region of Belo Horizonte, capital of the state of Minas Gerais, Brazil. The study site is in the buffer zone ( 〈 10 km) of two protected areas, where anthropogenic (urban areas and roads) and disturbed areas (burned fields) total a third of the study landscape. The main disturbances are mining activities, unregulated ecotourism and road proximity. Fecal samples (n= 95) collected between 2006 and 2008 revealed that the maned wolf frequently used both natural and disturbed fields. The diet was composed mostly of small mammals (9 species, 16.2 % of items and 92.6% of scats) and the plant Solanum lycocarpum (12.2% of items and 89.5% of scats), similar to what has been found in less disturbed areas. Overall diet diversity was, however, lower than has been found elsewhere, probably reflecting the poorer resource base of the study area. These results, together with recent findings from other sources, highlight the importance of buffer zones. They also suggest that the maned wolf is an ecologically flexible species that might be prone to hunt, and perhaps even survive, in disturbed areas outside protected areas.
