The north-central zone of Chile is described with respect to groundwater supply problems. In this region, groundwater is almost exclusively obtained from the thin alluvium in the main transverse valleys, which descend from the Andes in those sections where the valleys cross the northerly trending "central valley."

We describe the Holocene distribution of the Octodontids Aconaemys fuscus, Octodon bridgesi, O. degus, O. lunatus, O. pacificus and Spalacopus cyanus from Central Chile. We compared ancient and present day ranges. The Holocene pattern was inferred from zooarchaeological records. Octodon degus, O. lunatus, O. bridgesi, and Aconaemys fuscus showed a reduction in their geographic range. Although s...
