Geographical location of the study site in the Andes mountain range (small red square on the map; 35°59'56.1"S, 70°24'12.3"W) and panoramic view of the monitoring site inhabited by Alsodes pehuenche. This habitat corresponds to a system of Andean wetlands, with streams of varied flow and vegetative patches in which the Mulinum spinosum (“neneo”) plant predominates. The ESRI satellite image shows the georeferenced study site (white circle) and the monitored transect area (rectangle).
