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 ... -
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 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 nutrient and fibre tissue contents in Nothofagus pumilio trees growing at site quality and crown class gradients
(Elsevier, 2022-02-01)Estimation of biomass and nutrient contents in tree components are essential for evaluating the impact of harvesting on carbon fixation capacity, bio-element recycling, and long-term effect on the balance that influence ... -
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 ... -
Desarrollo de la regeneración a lo largo del ciclo del manejo forestal de un bosque de Nothofagus pumilio: 1. Incidencia de la cobertura y el aprovechamiento o cosecha
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 1999)La Lenga es la especie forestal de mayor impacto económico en la Patagonia. Dentro del bosque es posible encontrar una población importante de renovales, cuya supervivencia depende de la cantidad de luz que el dosel arbóreo ... -
Desarrollo de la regeneración a lo largo del ciclo del manejo forestal de un bosque de Nothofagus pumilio: 2. Incidencia del ramoneo de Lama guanicoe
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 1999)Los Nothofagus presentan inconvenientes para regenerarse cuando son sometidos a disturbios sistemáticos y permanentes, como lo es el sobrepastoreo. Los bosques de Tierra del Fuego, libres de ganado vacuno, son afectados ... -
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 ... -
Quality evaluation of Nothofagus pumilio seeds linked to forest management and climatic events
(Springer Nature, 2024-01-23)Forest ecosystems undergo significant transformations due to harvesting and climate fluctuations, emphasizing the critical role of seeding in natural regeneration and long‑term structural preservation. Climate change further ... -
Radial growth response to long-term thinning strategies in Nothofagus pumilio forests of Tierra del Fuego = Respuesta del crecimiento radial a estrategias de raleo de largo plazo en bosques de Nothofagus pumilio de Tierra del Fuego
(Faculty of Forest Sciences and Natural Resources, Austral University of Chile, 2023)New silvicultural proposals based on long-term trials are needed to develop forest management strategies. Radial growth response was the preferred proxy for managers to define thinning levels and best years for intervention. ... -
Seed fall and leaf litter relationships in Nothofagus pumilio forests: changes according to retention levels and years after harvesting
(Springer, 2023-04)Seed fall and leaf litter influence forest regeneration, nutrient cycling, and other key ecological processes closely related to forest management. In Patagonian forests, variation of both managed and unmanaged forests ... -
Survival and growth of Nothofagus pumilio seedlings under several microenvironments after variable retention harvesting in southern Patagonian forests
(Springer, 2014-05-01)Context: Variable retention prescriptions for Nothofagus pumilio forests provide for biodiversity conservation and natural regeneration by controlled opening of the canopy. Harvesting generates different microenvironments ... -
Turno de corta y posibilidad de los bosques de lenga (Nothofagus pumilio) en Tierra del Fuego (Argentina) = Rotation length and sustainable use of lenga (Nothofagus pumilio) forests in Tierra del Fuego (Argentina)
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2004)La ordenación forestal regional es una herramienta indispensable para desarrollar políticas forestales que protejan los bosques naturales, en el marco del manejo sustentable y del uso múltiple. Para ello se debe contar con ... -
Variable retention harvesting and climate variations influence over natural regeneration dynamics in Nothofagus pumilio forests of Southern Patagonia
(Elsevier, 2023-09-15)Natural regeneration is a key process to sustain structure, function, and composition in harvested forests over time. Variable retention harvesting system is a strategy that maintains a high level of heterogeneity in managed ...
