Habitat loss and fragmentation are the main causes ofbiodiversity decline, since changes in environmental andecological conditions directly affect species richness,abundance, and distribution. This study aimed to identifymedium- and large-sized mammals occurring in threeAtlantic Forest remnants located in the Barbacena campus of the Federal Institute of Southeast Minas Gerais (IFSudesteMG). Thespecies were recorded in track plots and through active search fordirect and indirect signs. 16 species distributed in six orders and 14families were identified, including some vulnerable and threatenedspecies such as Lycalopex vetulus (meadow fox), Lontra longicaudis(otter), and Callicebus nigrifrons (black-fronted titi monkey). Canisfamiliaris (domestic dog) and Didelphis sp. (opossum) were the speciesmost frequently observed in the track plots. The largest fragment hadthe greatest species richness, with 15 species, or 93.75% of the total.The number of species shared among the three sampled areas was31.2%. The similarities identified between the fragments indicate theneed for higher connectivity among them, through the creation ofecological corridors to allow the movement and, consequently, geneflux among the populations, favoring the maintenance of importantecosystem services in the region. Although small, the study areaplays a major role in mammal conservation in the region, preservingspecies from the Cerrado and the Atlantic Forest domains. To reducepotential impacts on the local fauna, management and conservationefforts should be put forward.Keywords: Fragmentation; biodiversity; mammalian fauna
