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 ... -
Above- and below-ground nutrient tissue concentration and leaf pigment changes in Patagonian woody seedlings grown under light and soil moisture gradients
(Taylor & Francis, 2011-10-28)To understand the ecophysiology of natural regeneration above- and below-ground nutrient tissue concentration and leaf pigment changes in Nothofagus pumilio (lenga) seedlings grown in three light intensities (4%, 26% and ... -
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 ... -
Canopy structure analysis for estimating forest regeneration dynamics and growth in Nothofagus pumilio forests
(Springer, 2011-04-08)Introduction Silviculture systems applied in Nothofagus pumilio forests are based on opening the canopy to stimulate natural regeneration by modifying light and soil moisture. The objective is to evaluate regeneration ... -
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 ... -
Carbon pool dynamics after variable retention harvesting in Nothofagus pumilio forests of Tierra del Fuego
(Springer Nature, 2023-01-23)Background It is necessary to determine the implications for managing forest stands using variable retention harvesting for maintaining carbon and for calculating the effects of different harvesting practices on above‑ and ... -
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 ... -
Composition and Spatial Variation of Germinable Seed Bank in Burned Nothofagus pumilio Forests in Patagonia Argentina
(MDPI, 2022-11-12)The availability of soil-stored seed determines initial plant functional types in post-fire landscapes. We evaluated the post-fire regeneration of Nothofagus pumilio forests, in Patagonia, Argentina, analyzing the soil ... -
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 ... -
Environmental variables influencing regeneration of Nothofagus pumilio in a system with combined aggregated and dispersed retention
(Elsevier, 2011-01-01)The current silvicultural prescriptions for Nothofagus are designed to stimulate natural regeneration by opening the canopy. One of these methods is variable retention, which can include either or both aggregated and ... -
Flowering and seeding patterns in primary, secondary and silvopastoral managed Nothofagus antarctica forests in South Patagonia
(Taylor & Francis, 2010-06-11)The success ofthe reproductive process in trees depends on abiotic and biotic factors that determine the final outcome of natural regeneration. Silviculture alters biotic and abiotic factors and results in secondary forest ... -
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 ... -
Integrated global assessment of the natural forest carbon potential
