Resumo

Studies carried out in Brazil revealed that Eucalyptus plantations shelter numerous species of small-size non-flying mammals. However, their distribution pattern inside the Eucalyptus plantations remains unknown. This study aimed at the identification of possible influence of distances from the remaining native revegetation areas and riparian systems, on spatial distribution and abundance of small-size mammals in Eucalyptus plantations. This study was carried at Eucalyptus stands recently planted (0-3 years) at the municipality of Angatuba, Sao Paulo state, Brazil between August 2007 and July 2009. The survey was carried out using pitfall traps at 14 sampling units inside Eucalyptus plantations 60-1130 m away from the borders. With a sampling effort of 2,449 bucket night, the experiment captured 680 individuals belonging to 12 species of small-size mammals (rodents and marsupials). The colonization process of Eucalyptus plantations was apparently initiated by generalist species from open Cerrado. In the present study, we did not find any clear correlation between specific richness and abundance of individuals and the distance from native revegetation areas or closer riparian systems. The study suggests that Eucalyptus plantations are permeable matrices to, at least, more generalist species present in the silvicultural landscapes (i.e. composed by an Eucalyptus plantation as the matrix and native vegetation patches). However, further studies must prioritize analyzing the influence of agricultural/sivilcultural practices (e.g., plantation structure and harvest frequency) on habitat quality and carrying capacity of agricultural/silvicultural landscape matrices, as well as implementing long-term monitoring programs to assess the impact of complete production cycles (some years) and along cycles of Eucalyptus plantations (some decades), on rodents population's diversity and dynamics patterns.
