Mammals, Volta Grande Environmental Unity, Triângulo Mineiro, states of Minas Gerais and São Paulo, Southeastern Brazil.

The Volta Grande Environmental Unity represents one of the few remnants of Cerrado protected by areserve in the Triângulo Mineiro region, municipalities of Conceição das Alagoas (19°55' S, 48°23' W) andMiguelópolis (20°12' S, 48°03' W), in the states of Minas Gerais and São Paulo, respectively. The mammalian fauna ofthis reserve was inventoried between 2003 and 2004 to generate estimates about taxonomic composition, richness, andabundance of species. A sampling effort of 832 trapping-nights resulted in 24 species recorded. Cumulative curvessuggest that the overall inventory is not complete and that more species are likely to be registered. The majority ofspecies recorded is widespread along the Cerrado, but include some noteworthy records of endangered species, such asthe Giant anteater (Myrmecophaga tridactyla) and the Manned wolf (Chrysocyon brachyurus). The record of thearboreal cricetid rodent Oecomys bicolor represents a slight extension of the southeastern limit of its distribution
