| Resumo: |
The Atlantic forest of Brazil is nowadays reduced to less than 8% of its total original area and yet many species remain to be described. The Atlantic Forest north to the São Francisco river - The Pernambuco Endemism Center (CEPE) - has less than 2% of its original forest cover and yet the knowledge on small mammals is scarce. Aiming to assess the small mammal community of this region surveys were carried out in 12 forest fragments of different sizes in distinct geographic areas of the CEPE. The capture-mark-recapture technique was used with live-traps set along linear transects. We recorded 15 species, two of which are in the IUCN Red List, but not in the Brazilian List of Threatened Species. The highest richness and abundance indices were recorded in medium-sized fragments and in the rainy season. More marsupial species were recorded compared to rodents. Our results suggest that fragmentation caused the extinction of those most specialized species, currently remaining only those most tolerant to fragmentation and urbanization. It is recommended that urgent measures should be taken to reconnect and restore these fragments to allow recolonization and reestablishment of the gene flow among the populations.
