Resumen:
Much of South America consists of diverse arid and semiarid regions characterized by high mammal endemismas a result of a complex interplay between place and lineage histories. In this review we summarize andhighlight several biogeographical and ecological features of the small mammals of South America drylands,with special focus on the Monte Desert biome. We provide information on population characteristics,community structure, food and habitat use, and responses to disturbances. Major findings at different scalesinclude the distinctiveness and high species turnover across South American drylands and Monte Desertecoregions; synchronous population fluctuations with high variability between years; herbivory and omnivoryas dominant trophic strategies; community structure organized through habitat and food segregation; and theimportance of a landscape mosaic of grazed and ungrazed areas for maintenance of small and medium-sizedmammal diversity.
