In the present study we investigated the species composition and abundance of a small mammal community from a "campo de murundus", a characteristic vegetational type of Central Brazilian Cerrados. Two grids of Sherman traps were set and eight species of rodents was recorded. No marsupials were found in this habitat. The most abundant species were Bolomys lasiurus (Lund, 1841), Thalpomys lasiotis Thomas, 1916 and Calomys tener (Winge, 1888). Bolomys lasiurus was the most abundant species during the rainy season and T. lasiotis was more common in dry season. This may be a mechanism allowing their coexistence in the same habitats.
