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
(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 ... -
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 ... -
Carbon (δ13C) and nitrogen (δ15N) stable isotope composition in plant and soil in Southern Patagonia’s native forests.
(Wiley, 2012-01)Stable isotope natural abundance measurements integrate across several biogeochemical processes in ecosystem N and C dynamics. Here, we report trends in natural isotope abundance (d13C and d15N in plant and soil) along a ... -
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 ... -
Climate change-related growth improvements in a wide niche-breadth tree species across contrasting environments
(Oxford University Press, 2023-05-09)Background and Aims The vulnerability and responsiveness of forests to drought are immensely variable across biomes. Intraspecific tree responses to drought in species with wide niche breadths that grow across contrasting ... -
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 ... -
Decomposition and nutrient release of grass and tree fine roots along an environmental gradient in southern Patagonia
(Wiley, 2018-10-25)Decomposition of fine roots is a fundamental ecosystem process that relates to carbon (C) and nutrient cycling in terrestrial ecosystems. However, this important ecosystem process has been hardly studied in Patagonian ... -
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 ... -
Effects of long-term low intensity silviculture and habitat on birds in Nothofagus antarctica forests of south Patagonia
(Elsevier, 2022-04-30)Low intensity silviculture has been used to decrease the impact of forest harvesting, for example, on bird species and structural diversity. The objective of this work was to analyse the long-term effect of thinning on ... -
Essential Nutrient and Trace Element Foliar Resorption of Two Co-Existing Nothofagus Species Grown Under Different Environmental Conditions in Southern Patagonia
(Frontiers Media, 2019-11)Nutrient resorption is crucial for mineral element conservation and efficiency of forest species, but knowledge on its significance and the mechanisms involved is still limited for most species and habitats. Focusing on ... -
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 ... -
