Distribuição da mastofauna de médio e grande porte em um mosaico florestal

Abstract

Medium and large mammals occur in all world ecosystems. Their ecological role

is very important, since they contribute for the maintenance of the equilibrium of their

communities. The mammal diversity in the Atlantic forest and, specifically, in the

Araucaria Forest (FO) of southern Brazil is very high. However, mainly due to the high

value of Araucaria angustifolia (the dominant species of the FO) as timber, this forest

formation has been intensely fragmented, with large areas being replaced by arboreal

plantations of both introduced and native species. In this study we investigated how the

medium and large-sized mammalian fauna uses a forest mosaic composed of patches of MOF

and plantations of Pinus spp., Eucalyptus sp., and also A. angustifolia. For data collection I

used trapping grids of sand track stations placed in all habitats (9 stations per grid, total area

of 0.64 ha), with three grids (replicates) for each habitat. In this stations I used three bait

types: banana, bacon and Pipdog. I es
