Mammalia, rodentia, sigmodontinae, irenomys tarsalis (Philippi, 1900) and geoxus valdivianus (Philippi, 1858): Significant ecological range extension

Abstract

We present the first records of the Chilean tree mouse (Irenomys tarsalis) and Valdivian long-clawed mouse (Geoxus valdivianus) in non-native forestry plantations. Despite being characterized as forest species, specimens of I. tarsalis and G. valdivianus were captured within a 30-year-old Pinus contorta plantation in Coyhaique National Reserve. These records show our limited understanding of this fauna and suggest the need for further surveys and monitoring, including disturbed habitats. © 2011 Check List and Authors.
