(Consejo Agrario Provincial de Santa Cruz (CAP), 2020-03)El Ñire (Nothofagus antarctica) es una especie forestal nativa que se caracteriza por su gran plasticidad adaptándose a una gran variedad de condiciones ambientales ocupando sitios con exceso de humedad (turberas y mallines) ... -
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 ... -
Análisis espacial de la efectividad de las reservas en la conservación de servicios ecosistémicos de distintos tipos de bosques en Tierra del Fuego
(Red Argentina de Ciencia y Tecnología Forestal, 2023-03-27)Los servicios ecosistémicos (SE) son bienes y beneficios que la sociedad obtiene de los sistemas naturales (Daily 1997), incluyendo aquellos económicos (ej. madera, comida) o no económicos (ej. valor estético, pertenencia). ... -
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
(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 ... -
Assessment of provisioning ecosystem services in terrestrial ecosystems of Santa Cruz Province, Argentina.
(Springer, 2021-04-27)Provisioning ecosystem services play an important role in the development of regional economies. Traditional managements usually intensify the supply of provisioning services, without consideration of other services (e.g. ... -
Árboles y sotobosque en sistemas silvopastoriles de Ñire ¿competencia o facilitación por N?
(Ediciones INTA, 2012-05-09)Si bien los bosques de Nothofagus antarctica son ampliamente utilizados como sistemas silvopastoriles, existen escasos estudios que evalúen las interacciones existentes entre los componentes árboles y pastizal. En este ... -
Área demostrativa manejo de ñirantal: Aplicando a escala real los conocimientos.
(Ediciones INTA, 2017-11)Desde el año 2011 la estancia comenzó a aplicar la separación de ambientes como un criterio significativo en el manejo de los cuadros, además del uso de descansos para la recuperación del pastizal. En el mismo año incorporó ... -
Biodiversity potential of Nothofagus forests in Tierra del Fuego (Argentina): tool proposal for regional conservation planning
(2016-09)It is difficult to map and quantify biodiversity at landscape level in areas with low data availability, despite demand from decision-makers. We propose a methodology to determine potential biodiversity pattern using habitat ... -
El cambio climático en los bosques
(REDFOR.ar - ArgentinaForestal - CONICET, 2021-12)El cambio climático es un factor de gran incidencia sobre el desarrollo normal de los diferentes ecosistemas debido al aumento de la temperatura y los cambios sustanciales en los patrones de precipitación, que hacen necesario ... -
