TROVATI, Roberto Guilherme; DE BRITO, Bernardo Alves  y  BARBANTI DUARTE, José Maurício. Home range and habitat use of crab-eating fox (Cerdocyon thous Linnaeus, 1766), in the Cerrado of the central region of Tocantins, Brazil. Mastozool. neotrop. [online]. 2007, vol.14, n.1, pp.61-68. ISSN 0327-9383.

Cerdocyon thous is a species widely distributed in Brazil, in a variety of habitats ranging from open area to forests and in the central region of Tocantins (Brazil) is relatively abundant. Nevertheless, literature related to habitat use and home range of this canid in the Cerrado biome is scarce. Therefore, the aim of this study was to evaluate the use of habitat and home range of this species in the Cerrado of the central region of Tocantins. After capturing and monitoring three animals by radiotracking, we concluded that all animals spent most of their time in cerrado latu sensu and strictu sensu. Their home range varied from 2.50 to 6.72 for the MCP (Minimum Convex Polygon) and from 5.33 to 7.23 for HM (95% Harmonic Mean). The core area (area with greatest concentration of localization 75% HM) was 44% of the home range calculated for 95% HM. Thus, the present study contributes to the ecology of this canid with valuable information in one of the most threatened biomes in the world.
