| Abstract | |
Eucalyptus plantations currently cover 4.5 million hectares of Brazilian territory. This forestry is expanding mainly over areas of extensive livestock production. The effects of the replacement of pastures by eucalyptus plantations on the distribution of small mammals are still unknown. In this context, this study aimed at to identify the distribution pattern and abundance of small mammals in an area where recently cattle pastures were converted into eucalyptus plantations. This study was carried out at Fazenda Três Lagoas and Fazenda Arca in the municipality of Angatuba, located in the Upper Paranapanema river basin, between August 2007 and July 2009. The small mammals survey was carried out with pitfall traps distributed in 30 sampling units. Fourteen species of orders Didelphimorphia and Rodentia were captured. The abandoned pasture and the native vegetation presented a higher abundance and species richness in relation to the eucalyptus plantations. The taxocenosis of small mammals in this silvicultural landscape resembles those found in other agricultural landscapes. These results together and the current land use trend suggest that eucalyptus plantations can be relatively to small mammals. However, the remnants of native vegetation in silvicultural landscapes are essential to the conservation of these species. (AU) | |
