摘要：

Comparisons of species composition in prehistoric (8.0 x 10(3) to 1.2 x 10(3) years ago) and contemporary assemblages of caviomorphs from central Chile reveal that species richness has decreased through the Holocene. The local extinction of two species, Aconaemys fuscus and Octodon bridgesi, suggests that current assemblages are impoverished and nested subsets of prehistoric caviomorph assemblages.
