A review of silvopastoral systems in native forests of Nothofagus antarctica in southern Patagonia, Argentina
(2016-12)Silvopastoral systems in Nothofagus antarctica (ñire) forest have become an economical, ecological and productive alternative in Patagonia. Southern Patagonia’s experience over the past 12 years with silvopastoral systems ... -
Allometric relations for biomass partitioning of Nothofagus antarctica trees of different crown classes over a site quality gradient
(Elsevier, 2010-03)Data on tree biomass are essential for understanding the forest carbon cycle and plant adaptations to the environment. We determined biomass accumulation and allometric relationships in the partitioning of biomass between ... -
Anthropogenic Impacts Allowed for the Invasion of Understory Species, Affecting the Sustainability of Management Practices in Southern Patagonia
(MDPI, 2024-01-16)Forest management aims to preserve integrity and ecosystem resilience. Conservation and species invasion patterns must be determined in managed landscapes. The objectives of this study were to identify proxies that allowed ... -
Aspectos ecológicos de la regeneración por semillas en bosques nativos de Nothofagus antarctica en Patagonia Sur, Argentina = Ecological aspects of regeneration from seeds of Nothofagus antarctica native forest in Southern Patagonia, Argentina

Carbon accumulation along a stand development sequence of Nothofagus antarctica forests across a gradient in site quality in Southern Patagonia
(Elsevier, 2010-06-25)Above- and below-ground C pools were measured in pure even-aged stands of Nothofagus antarctica (Forster f.) Oersted at different ages (5–220 years), crown and site classes in the Patagonian region. Mean tissue C concentration ... -
Changes in forest structure modify understory and livestock occurrence along the natural cycle and different management strategies in Nothofagus antarctica forests
(Springer Nature, 2022-08-17)Sustainable forest management is proposed as a solution for many ecological and socioeconomic trade-offs associated with different forest uses. In Patagonia, silvopastoral systems were proposed to balance provisioning ... -
Conservation values of understory vascular plants in even- and uneven-aged Nothofagus antarctica forests
(Springer, 2020-09)Usually, stands with aging trees are considered forests with higher conservation values, regardless their structural diversity and other functional attributes. Natural stands present a wide range of age structures, from ... -
Diversidad de plantas vasculares en bosques continuos y relictuales de Nothofagus antárctica (Nothofagaceae) en Patagonia austral
(Universidad de Magallanes, Chile, 2019)La historia de los bosques de Nothofagus antarctica (ñire, ñirre) está asociada a profundos disturbios geológicos y climáticos. A éstos se le suman los disturbios más recientes, que junto a los usos culturales de la tierra ... -
Forest carbon management strategies influence storage compartmentalization in Nothofagus antarctica forest landscapes
(Canadian Science Publishing, 2023-10)Silvopastoral systems are one of the strategies proposed to manage natural forests in southern Patagonia for livestock and timber purposes. In the context of climate change, it is necessary to design new management proposals ... -
In vivo oral toxicity and antioxidant capacity of Nothofagus antarctica (G.Forst.) oerst (ñire) leaves
(Taylor & Francis Group, 2024-01-04)Nothofagus antarctica (NA) is a native tree of Patagonia. Since ancient times, NA leaves were used in infusions for medical and food purposes, but there are no deep insights on its toxicity. The aim of this work was to ... -
Interacciones ecológicas en bosques de Nothofagus antarctica bajo uso silvopastoril en Patagonia sur continental
(Asociación Española de Ecología Terrestre, 2018-12)Los bosques de ñire (Nothofagus antarctica) en el sur de Patagonia se ubican mayoritariamente limitando con la estepa. De esta manera, han sido utilizados como sistemas silvopastoriles con ganadería ovina y/o bovina desde ... -
Leaf wettability, anatomy and ultra-structure of Nothofagus antarctica and N. betuloides grown under a CO2 enriched atmosphere
(Elsevier, 2023-01)Increasing CO2 air concentration may affect wettability, anatomy and ultra-structure of leaves of Patagonian forest species, evergreen and deciduous plants potentially responding differently to such CO2 increases. In this ... -
Litter decomposition and nutrients dynamics in Nothofagus antarctica forests under silvopastoral use in Southern Patagonia.
(Springer, 2012-01-24)The role of environmental variables on litter decomposition and its nutrient release in Nothofagus antarctica forest in Patagonia is poorly understood. Moreover, in these forests under silvopastoral use there are few ... -
Litterfall and nutrients return in Nothofagus antarctica forests growing in a site quality gradient with different management uses in Southern Patagonia
(2015-01)We evaluated the annual litterfall and nutrients return in primary forests of Nothofagus antarctica growing at three different site classes (SC) (III, IV and V) and compared two of these forests with adjacent stands under ... -
Masting has different effects on seed predation by insects and birds in antarctic beech forests with no influence of forest management
(2017-09-15)Mast seeding is characteristic of many long-lived tree species and widely proposed as a mechanism to reduce seed predation. However, whether the efficiency of this reproductive response may vary depending on type of seed ... -
