Abstract

KELT, Douglas A.; ENGILIS JR., Andrew; TORRES, Irene E.  and  HITCH, Alan T.. Ecologically significant range extension for the chilean tree mouse, Irenomys tarsalis. Mastozool. neotrop. [online]. 2008, vol.15, n.1, pp.125-128. ISSN 0327-9383.

We document a capture of the Chilean tree mouse (Irenomys tarsalis) from ecologically anomalous habitat near Pto. Ibáñez, Chile, near the xeric end of the transition from temperate rainforest to steppe. Typical of Nothofagus forest, a single reproductively active male specimen was captured in a shrubby riparian corridor ca. 40 km S and 900 m lower in elevation than the nearest forested region. This record underscores our limited understanding of this fauna, and calls for further surveys and monitoring in key habitats in this region.

Keywords : Chilean tree mouse; Patagonian Chile; Range extension.
