Past and present small mammals of Isla Mocha (Chile)

Saavedra, B.; Quiroz, D; Iriarte J


We describe archaeozoological and extant small mammals from Isla Mocha, an island located in south-central Chile. Species composition was compared among past and present assemblages. Also composition, as well as individual and population parameters were compared among island habitats. Specimens from archaeological sites included Oligoryzomys longicaudatus, Abrothrix sp., and Octodon pacificus, whereas Abrothrix longipilis, A. olivaceus, Oligoryzomys longicaudatus, and Geoxus valdivianus were captured. Higher richness was observed in intermediate-disturbed habitat. Body size and tail length, as well as body mass did not vary among island habitats for A. longipilis or A. olivaceus. Higher abundance was associated to less perturbed habitat.
