The richness ofthe large and medium-sized mammals ofthe Serra do Divisor National Park (Acre, Brazil). The objective ofthe present study was to characterize the richness (number of species) of large and medium-sized mammals, and the antropic threats in the Parque Nacional da Serra do Divisor (PNSD). ln 31 days data were collected ÚlI"ough direct observations or evidences (bones, hairs, vocalizations and tracks) along pre-existing trails distributed in different types ofvegetation. Wild mammals captured by local people were also considered. They were found 44 species of terrestrial mammals (with the exception of small mammals and bats) and two species of cetaceans, representing 73% of the total predicted, according to the Iiterature and information oflocal dwellers were registered in PNSD. They exist in the area two species classified by IUCN (1996) as "Endangered" [Cacajao calvus rubicundus (I. Geoffroy, 1806) and Priodontes maximus (Kerr, 1792)] and five as "Vulnerable" [Ateies chamek (Humboldt, 1812), Callimico goeldii (Thomas, 1904), Lagothl"ix lagotricha poeppigii (Humboldt, 1812), Myrmecophaga tridactyla Linnaeus, 1758 and fnia geoifrensis (Blainville, 1817)]. Given that subsistence and commercial hunting are common in the PNSD, mammals more affected by hunting [A/eles chamek (Humboldt, 1812), Lagothrix lago/ricllO (Humboldt, 1812), Tayassll pecari (Link, 1795)] were observed only in the more remote areas such as Serra do Divisor, Rio Moa. ln comparison with others areas, the results indicate that PNSD has high richness of the mammals, with special attention to the 14 primates species registered.
