MARTINEZ, Omar; RECHBERGER, Josef; VEDIA-KENNEDY, Javier  and  MESILI, Thibeault. The medium and large mammals of the Serranía del Aguaragüe, Tarija (Bolivia). Mastozool. neotrop. [online]. 2008, vol.15, n.2, pp.335-348. ISSN 0327-9383.

The southern slopes of the Bolivian sub-Andean are among those considered poorly known in terms of local biodiversity. Although it is known that the region harbors mammal species typical of the Chaco and transitional forests, few surveys of mammals were conducted. We present an annotated check-list of the medium and large mammals of the Serranía del Aguaragüe National Park and Natural Area of Integrated Management, Tarija (Bolivia). In the Serranía del Aguaragüe, faunal elements from the eastern Chaco forest converged with elements of western montane forest. During 18 months (2003 to 2006) we study the mammals in five localities in the central part of the park and one locality in the southern part in a gradient between 400 to 1600 m in elevation. We completed a total effort of 350 days of fieldwork, 1319 km by transects, 72 interviews, and 272 km of random walks. The species were identified by direct observation and indirect methods. We recorded 32 species of mammals, of which Panthera onca, Tremarctos ornatus, Tapirus terrestris, and Tayassu pecari are threatened species.

Keywords : Bolivian Tucuman Forest; Chacoan Forest; Serranía del Aguaragüe.
