Este artigo relata um estudo feito com duas fêmeas adultas de tamanduá-mirim (Tt1 e Tt2) que foram translocadas e monitoradas por radiotelemetria no Cerrado brasileiro. O deslocamento dos dois animais foi de, aproximadamente, 6 km em seis dias; ambos se estabeleceram em fi sionomias abertas de cerrado; Tt1 veio a óbito 21 dias após ser solto, não sendo possível determinar sua área de uso, e Tt2 sobreviveu por quatro meses, estabelecendo área de uso de 1,06 km² (MCP 95%). Constatou-se que há necessidade de mais estudos para avaliar a viabilidade das translocações e, para isso, devem se considerar as predições propostas pela International Union for Conservation of Nature.

The brown-nosed coati (Nasua nasua) is a carnivorous species found in all the Brazilian biomes, some of which are endangered areas. The aim of this work was to determine the habitat use and selection, home range and core area of N. nasua in the Cerrado biome, central region of Tocantins, Brazil. The study was carried out in an area of approximately 20 000ha from May 2000 to July 2002. A total of seven box traps were placed in the area for 13 months, three of 11 captured animals were followed and monitored by radio-tracking during 13 months. The monitoring was conducted once a day, three times a week using a car and walking through the study area (radio-tracking and visual contact). The results demonstrate that these three males used more frequently the gallery forest formation, followed by cerrado and wetlands. The use of gallery forest by these animals indicated an habitat selection (Proportion test, z=12.98, p< 0.01). Besides, adult males used the gallery forest more frequently (Fisher's exact test, p<0.01) and wetlands less frequently (Fisher's exact test, p<0.01) than juvenile males, without significant differences between animal ages for cerrado percentage of habitat use. Besides, results also showed a gallery forest selection by adult (Proportion test z= 13.62, p<0.01) and juvenile (Proportion test z=2.68, p<0.01) males, and a wetland selection by the juvenile male (Proportion test z=3.90, p<0.01). The home ranges varied from 2.20 to 7.55km 2 for the Minimum Convex Polygon 100% (MCP 100%) and from 4.38 to 13.32km 2 for the Harmonic Mean 95% (HM 95%). The smallest home range overlap occurred between the adult males (Nm1 and Nm3), and the greatest between the juvenile Njm2 and the adult Nm1. The average of the core area (HM 75%) for the three monitored animals represented 21.29% of the home range calculated with HM 95%. No overlap between core areas was observed for adult males, but, it was an overlap between the core area of the juvenile male and its band with that of the two adult males. The present study provides new data on core area size and frequency habitat use by adult and juvenile males of N. nasua in the Brazilian Cerrado, that may support conservation efforts.
