Abstract

The Pernambuco Endemism Center (CEP, acronym in Portuguese) has remnants of Atlantic Forest, but with a high degree of degradation due to more than 300 years of deforestation. Recent studies carried out in this area with mammals report species that are endemic to Brazil, such as the Coandu-Mirim (Coendou speratus), thus showing the importance of the CEP and the need for studies for its conservation. However, only about 52% of mammal species recorded in past centuries in the region were observed in a study based on eight years of sampling in transects by direct observation. The present work aims to survey the mammalian community and reassess the presence of species considered locally extinct in the CEP, using DNA samples obtained from blood-sucking mosquitoes and blowflies in conjunction with metabarcoding analysis. The use of this approach has been shown to be as or more efficient when compared to traditional sampling methodologies, including recording rare or elusive species and this study should make an important contribution to a better understanding of the fauna still existing in the CEP and its conservation.
