Abstract

SAAVEDRA, BÁRBARA  and  SIMONETTI, JAVIER A. Holocene distribution of Octodontid rodents in central Chile. Rev. chil. hist. nat. [online]. 2003, vol.76, n.3, pp.383-389. ISSN 0716-078X.  http://dx.doi.org/10.4067/S0716-078X2003000300004.

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 specific mechanisms remain to be tested, human disturbance seems to be the distal factor that explains the reduction of ranges for some taxa.

Keywords : Octodontidae; Holocene; central Chile; zooarchaeology.
