Mammalia, Rodentia, Sigmodontinae, Irenomys tarsalis (Philippi, 1900) and Geoxus valdivianus (Philippi, 1858): significant ecological range extension

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.
