Resumen:
ABSTRACT: Morphologic-ecological records of Microcavia australis (Caviidae, Rodentia)in the Puna of San Juan Province, Argentina. All available information abouthistory of life of Microcavia australis corresponds to zones of Espinal-Monte transition andthe temperate Monte in Mendoza; there are no references for other places in the Monteor for the Puna. In this work, evidences of the presence of M. australis appear at altitudeshigher than 2500 m, the highest altitude previously cited for this species. Its morphology,habitat and diet are also described. The study was carried out at El Leoncito National Park,San Juan (2953 m, 31º 47 S, 69º 11 W). Our results show a decrease in body size asaltitude and climatic rigor increase. This could be related to physiological and behavioralstrategies in response to lower availability of energy and to environmental restrictions.Nevertheless, new captures should be carried out in order to analyze in more detail thispeculiar record of M. australis in the Puna.
