Seasonal diet of guanaco (Lama guanicoe) linked to vegetation life forms and environment types in Tierra del Fuego (Argentina)
Large diversity of habitat types, plant species assemblages, and silvopastoral activities in Nothofagus spp. forests condition the food availability for native herbivores. This work evaluates the seasonal diet of Lama guanicoe linked to plant life forms and habitat types in sub-Antarctic forests. Th...
