Seasonal diet of Lama guanicoe (Camelidae: Artiodactyla) in a heterogeneous landscape of South Patagonia
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...
