Resumen
UDRIZAR SAUTHIER, Daniel E; PAZOS, Gustavo E; CHELI, Germán H y CORONATO, Fernando. Mamíferos terrestres en islas del Atlántico Sudoccidental, Patagonia, Argentina. Mastozool. neotrop. [online]. 2017, vol.24, n.1, pp.251-256. ISSN 0327-9383.
The aim of this study was to survey the species of terrestrial mammals in the main islands of the Parque Interjurisdiccional Marino Costero Patagonia Austral (PIMCPA). This study was conducted in Leones, Tova, Tovita and surrounding smaller islands. Small mammals were surveyed with trapping; these and other species were documented with walking transects and analysis of raptor pellet. Seven species of land mammals were recorded in total. In Leones island three species were found: big hairy armadillo (Chaetophractus villosus), small big-eared brown bat (Histiotus montanus) and Norway rat (Rattus norvegicus), while in Tova and Tovita islands four species were identified: feral cat (Felis catus), southern mountain cavy (Microcavia australis), European rabbit (Oryctolagus cuniculus) and pichi (Zaedyus pichiy). The presence of introduced species could generate conflicts with marine birds nesting in these islands.
