Are there different vigilance strategies between types of social units in Lama guanicoe?
(Elsevier, 2019-10)Group vigilance is a cooperative behaviour in social species that reduces individual risk of predation. Lama guanicoe is a social species of camelid performing cooperative vigilance, but little is known about the vigilance ... -
Desarrollo de la regeneración a lo largo del ciclo del manejo forestal de un bosque de Nothofagus pumilio: 2. Incidencia del ramoneo de Lama guanicoe
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 1999)Los Nothofagus presentan inconvenientes para regenerarse cuando son sometidos a disturbios sistemáticos y permanentes, como lo es el sobrepastoreo. Los bosques de Tierra del Fuego, libres de ganado vacuno, son afectados ... -
Effectiveness of fencing and hunting to control Lama guanicoe browsing damage: Implications for Nothofagus pumilio regeneration in harvested forests
(2016-03-01)Browsing damage by native ungulates is often to be considered one of the reasons of regeneration failure in Nothofagus pumilio silvicultural systems. Fencing and hunting in forests at regeneration phase have been proposed ... -
Holistic versus continuous grazing in Patagonia: A station-scale case study of plant and animal production
(Elsevier, 2021-01)We compared animal and vegetation responses of a 13 600-ha area under holistic grazing management (HGM) with a similar area under continuous grazing (CGM) in a Patagonian station. Limitations were a dry 2012 −2016 experimental ... -
Male aggressiveness in a polygynous ungulate varies with social and ecological context
(Wiley, 2021-01)Aggression is a social behaviour which can be affected by numerous factors. The quality and quantity of food resources may play an important role in the aggressiveness of territorial ungulates as the defence of these ... -
Reproductive flexibility in South American camelids: First records of alternative mating tactics in wild guanacos (Lama guanicoe) = Flexibilidad reproductiva en camélidos sudamericanos: Primeros registros de tácticas de apareamiento alternativas en guanacos silvestres (Lama guanicoe)
(Sociedad Argentina para el Estudio de los Mamíferos (SAREM), 2020-06)Intraspecific variation in mating behavior has been documented in diverse taxa, including ungulates. Here, we report and describe for the first time the existence of alternative mating tactics in a wild guanaco (Lama ... -
Seasonal diet of Lama guanicoe (Camelidae: Artiodactyla) in a heterogeneous landscape of South Patagonia = Dieta estacional de Lama guanicoe (Camelidae: Artiodactyla) en un paisaje heterogéneo de Patagonia Sur
(Universidad Austral de Chile, Facultad de Ciencias Forestales, 2013)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 ... -
Where are the males? The influence of bottom-up and top-down factors and sociability on the spatial distribution of a territorial ungulate
(Springer, 2022-01)The factors that regulate the abundance and distribution of wild herbivores are key components of a species’ ecology and include bottom-up and top-down mechanisms, as well as aspects related to social organization. In ...
