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 ... -
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
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2011)Los objetivos de este estudio fueron cuantificar la producción anual de semillas y su viabilidad germinativa en rodales puros de Nothofagus antarctica (ñire) desarrollándose en tres calidades de sitio, y evaluar el ... -
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 ... -
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 ... -
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 ... -
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 ... -
Microclimatic conditions restrict the radial growth of Nothofagus antarctica regeneration based on the type of forest environment in Tierra del Fuego
(MDPI, 2023-05-27)Regeneration is crucial for forest continuity in natural and managed stands. Analyzing intra-annual dynamics can improve the understanding between growth and climate, identifying regeneration survival thresholds. The ... -
Microorganismos del suelo en bosques de ñire en Patagonia Sur: resultados preliminares.
(Instituto Forestal (INFOR), 2017-08)Nothofagus antarctica (ñire) es una especie nativa del bosque andino-patagónico que se extiende desde los 36º 30’ hasta los 56º 00’ LS. Es la segunda especie en importancia de la provincia de Santa Cruz, Argentina. En estos ... -
Partición diferencial de nutrientes en arboles de Nothofagus antarctica creciendo en un gradiente de calidades de sitio en Patagonia Sur = Different nutrient allocation in Nothofagus antarctica trees growing over a site quality gradient in South Patagonia
(2013)Nothofagus antarctica (ñire) es una especie nativa caducifolia que crece al sur de Argentina y Chile. Estudiar la distribución de nutrientes en árboles es importante como base para el entendimiento de la dinámica de los ... -
Regeneración por semillas en bosques nativos de Nothofagus antarctica bajo uso silvopastoril en Patagonia Sur, Argentina = Seed regeneration in native forests of Nothofagus antarctica under silvopastoral use in Southern Patagonia, Argentina
(2013-03)Los objetivos de este estudio fueron: i) evaluar la regeneración, desde el punto de vista de su producción y calidad de semillas, así como también de la instalación y supervivencia de plántulas, de dos rodales puros de ... -
Silvopastoral use of Nothofagus antarctica in Southern Patagonian forests, influence over net nitrogen soil mineralization
(2013-04)In most temperate forest, nitrogen (N) is considered a limiting factor. This becomes important in extreme environments, as Nothofagus antarctica forests, where the antecedents are scarce. Thinning practices in N. antarctica ... -
State and transition model approach in native forests of Southern Patagonia (Argentina): linking ecosystem services, thresholds and resilience
(Taylor & Francis, 2017-04)The sustainable use of ñire forests requires knowledge of its dynamics and management to maintain long-term main forest ecosystem services. The aim of this work was to develop a structural–functional state and transition ... -
Ten years of seed production and establishment of regeneration measurements in Nothofagus antarctica forests under different crown cover and quality sites, in Southern Patagonia
(2018-06)This study evaluated the seed production and quality and the subsequent regeneration establishment in five pure Nothofagus antarctica forests growing at different site qualities and crown cover during 10 years, in Southern ...
