Densidad y desplazamiento de Phyllotis limatus, un roedor del desierto de Atacama

Abstract

Phyllotis limatus is an inhabitant of the Atacama Desert, where it is distributed in arid costs and Pacifi c Andean slopes, reaching 4.000 meters. With the implementation of a study of wildlife in a Chilean Prepuna area, we capture and mark small mammals (marking with microchip). From these records, we studied the movement and density of the specie in a high semidesert environment. Movements registered were able to record up to 2.5 km in a relocated individual and 1.2 km in a resident individual. Similarly, we note that the densities of Phyllotis in these extreme environments are low and probably this is related to the environmental cost in these ecosystems.
