Resumen:
A rocky habitat, in its broadest sense, may be described as any locality that contains boulders, rocks, scree, pebbles, outcrops, cliffs, or caves. In these habitats, mammals find shelter sites that they use as nesting sites or dens to raise their young in a stable microclimate that is relatively secure from predators. The aim of this study was to characterize and evaluate the microhabitat selection by the southern mountain cavy (Microcavia australis) in a rocky habitat. This rodent selected the highest and deepest crevices, which provided them with a more stable microenvironment than outside. The present study is the first to report a southern mountain cavy population associated with a rocky habitat, suggesting a strong plasticity to inhabit a variety of habitats, as indicated by its wide distribution.
