Abstract

GUZMAN, Jonathan A; ORTIZ, Juan Carlos  and  CANON, Carola. Variación morfológica de Oligoryzomys longicaudatus magellanicus (rodentia: sigmodontinae) al oeste de los campos de hielo patagónico sur en Chile. Mastozool. neotrop. [online]. 2015, vol.22, n.2, pp.375-384. ISSN 0327-9383.

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.

Keywords : Islands; Morphological variation; O. l. magellanicus; Rodentia; Western Patagonia.
