    MAMÍFEROS MEDIANOS Y GRANDES DE LA SERRANÍA DEL AGUARAGÜE, TARIJA (BOLIVIA)
    (Smithsonian Institution, 2008) Omar Martínez; Josef Rechberger; Javier Vedia-Kennedy; Thibeault Mesili
    The medium and large mammals of the Serrania del Aguarague, Tarija (Bolivia). 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 Serrania del Aguarague National Park and Natural Area of Integrated Management, Tarija (Bolivia). In the Serrania del Aguarague, 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 re- corded 32 species of mammals, of which Panthera onca, Tremarctos ornatus, Tapirus terrestris, and Tayassu pecari are threatened species.

    Riqueza específica y especies de interés para la conservación de la avifauna del área protegida Serranía del Aguaragüe (sur de Bolivia)
    (2011) Omar Martínez; Oswaldo Maillard Z.; Javier Vedia-Kennedy; Mauricio Herrera; Thibeault Mesili; Abraham Rojas
    We studied the avifauna of 11 localities of the Serranía del Aguaragüe National Park and Natural Area of Integrated Management, Gran Chaco Province, Tarija Department, Bolivia. A total of 272 species were recorded, 6 of which were threatened (Buteogallus coronatus, Ara militaris, Amazona tucumana, Vultur gryphus y Buteogallus solitarius). This study includes 11 new species records for Tarija Department and 14 that were previously known by a few records. Twenty-nine species were zoogeographical endemisms: 20 for Central South America region and 9 for Central Andes region. The Serranía del Aguaragüe National Park and Natural Area of Integrated Management is an important area with convergent avifaunistic elements belonging to western mountain forests and eastern Chaco, along with several migrant species, especially austral ones.
