- Abstract
Oligoryzomys is one of the most widely distributed mammal genera in Chile. We describe morphological variation among specimens from west of the Southern Patagonian Ice Fields, between 48° S and 51° S. Univariate and multivariate analysis showed no significant differences between sexes, but uncovered significant geographical variation. Island specimens had higher values for almost all characters evaluated, which could correspond to the absence of predators and competitors. Based on morphological and distributional information, we suggest that individuals analyzed belong to the subspecies Oligoryzomys longicaudatus magellanicus.
