Pablo Teta, Javier A. Pereira, Natalia G. Fracassi, Silvina B.C. Bisceglia, Sofía Heinonen Fortabat

Se estudió la comunidad de pequeños mamíferos terrestres (< 500 g) del Parque Nacional Lihué Calel (37° 57′ S, 65° 33′ O, provincia de La Pampa, Argentina) en 1993 y entre los años 2003 y 2006. Se documentaron datos sobre hábitat, ecología, reproducción y estructura de la población en los marsupiales Lestodelphys halli y Thylamys pallidior, los cricétidos Akodon azarae, Akodon molinae, Calomys musculinus, Eligmodontia typus, Graomys griseoflavus, Oligoryzomys longicaudatus y Reithrodon auritus, y los caviomorfos Ctenomys cf. C. azarae, Galea musteloides, Microcavia australis y Tympanoctomys barrerae.

Small mammals (Didelphimorphia and Rodentia) from Parque Nacional Lihué Calel, La Pampa Province, Argentina. We studied the terrestrial small mammal (< 500 g) assemblage from Parque Nacional Lihué Calel (37° 57′ S, 65° 33′ W, La Pampa Province, Argentina) in 1993 and 2003–2006. Information about habitat, ecology, reproduction, and population structure is provided for the didelphid marsupials Lestodelphys halli and Thylamys pallidior, the cricetid rodents Akodon azarae, Akodon molinae, Calomys musculinus, Eligmodontia typus, Graomys griseoflavus, Oligoryzomys longicaudatus, and Reithrodon auritus, and the caviomorph rodents Ctenomys cf. C. azarae, Galea musteloides, Microcavia australis, and Tympanoctomys barrerae.

Nuevos aportes para el conocimiento de la mastofauna del Parque Nacional Calilegua (Provincia de Jujuy, Argentina)

Sofía Heinonen Fortabat, Andrés Bosso

Seventy-four species of mammals are cited after two surveys trips to Calilegua National Park, Ledesma and Valle Grande Departaments, Province of Jujuy, Argentina. The information was completed with a deep bibliography research and personal comments. The mammal community presents differences in its composition in relation with the altitude and the phytogeographical structure. In the transition forest (500 m altitude) occurs the majority of the species (62%), with an important chacoan fauna ingression. Excepting Rodentia, all the orders show decreased values to higher altitudes. Systematic and taxonomic information of the species are analyzed.
