Resumen:
We evaluated the effects of land use on the distribution of 3 sympatric species of armadillos, Chaetophractus
villosus, C. vellerosus, and Dasypus hybridus, on 34 farms in the eastern Pampas. We characterized 4 soil and
vegetation variables around each burrow located during surveys of these farms, and related burrow abundance to
10 variables used to characterize each farm. C. vellerosus was the most specialized, using primarily native
woodlands and areas with calcareous soil. D. hybridus was associated with natural grasslands and avoided
cultivated pastures, and was negatively related to the number of dogs that lived on the farms. C. villosus, the most
abundant species, was found in all 4 types of habitats, but its distribution depended on the intensity of hunting on
each farm.
