RESUMO

The physique space is a major dimensions of the niche of a species as the way is used for determining a series of interactions with the ecological environment. In the present study we estimated the size of the home range and habitat selection considering two scales of selection (second and third order) by brown brocket deer (Mazama gouazoubira) in the sub-region Nhecolândia, Pantanal, Mato Grosso do Sul state. Were captured and used three individuals brown brocket deer in the analyzes. VHF radio-collars (conventional telemetry) and collars GPS (digital telemetry) were used to determine the locations of the animals. The total period of monitoring was 6 months and covered the late dry season and rainy season of the year 2010-2011. The digital telemetry from individuals monitored (control deer) allowed a simulated projections in the surface area of conventional subjects monitored by telemetry. The deer brown brocket showed an average area of 73.2 ± 32.9 ha by the minimum convex polygon method considering the correction of areas obtained by VHF telemetry. On the scale of the second order of selection forest habitat category (chains and capons of forest) was the only positively selected by the individuals analyzed. The selection was tested using the chi-square goodness of fit and using the Bonferroni confidence interval. On the scale of the third order, although no significant difference in the use of categories of vegetation in relation to the availability, open areas like fields and edges of the bay habitats were important with regard to obtaining forage resources. It was concluded that the deer brown brocket is a species of deer that requires a relatively small area to meet your requirements and has the chains and capons of forest as a habitat of great importance as regards the allocation of its area of use.
