• Resumen

  • In this paper, we evaluated spatial patterns in mammalian fauna obtained using 75,000 camera-trap hours in 33 fragments at the Cerrado-Pantanal border, along an east-west axis and flanked by two relatively large preserved areas. This region has been proposed as an ecological corridor, connecting these two large ecosystems. The richness of species obtained (total = 33) was explained by the area and the number of habitats in each fragment. The abundance of small-bodied species tends to have significant spatial patterns, whereas variation in the abundance of large-bodied species is randomly distributed in the geographical space. No faunal transition (changes in species compositions) between the two ecosystems was identified.
