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. ... -
Respuesta anatómica y fisiológica de especies de Nothofagus de Patagonia austral ante la variación de temperatura, humedad, CO2 y nutrientes
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2021-04-05)Tomando los bosques nativos de Nothofagus de la Patagonia austral como objeto de estudio, se han desarrollado diversas investigaciones en los distintos capítulos de la tesis, para evaluar la respuesta de estas especies ... -
Role of abiotic factors in nothofagus pumilio forest mortality: the sensitivity of ecotones
(Elsevier, 2021-04-24)The world's forests are being affected by a changing climate. Recently, patches of dead trees have been found in forests of the Patagonian endemic species Nothofagus pumilio, which could not be related to insects or ... -
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 ... -
Servicios ecosistémicos del bosque andino patagonico de la provincia del Chubut: efectos de la ganaderia bovina sobre los recursos suelo y agua
(Universidad Nacional del Comahue, 2023-07)La ganadería ha tenido diferentes impactos sobre los bienes y servicios ambientales que ofrecen los ecosistemas. El impacto del ganado afecta a los recursos suelo y agua producto del pisoteo, ramoneo y deposición de orina ... -
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 ... -
Temperature and day length drive local adaptation in the Patagonian foundation tree species Nothofagus pumilio
(BioRxiv, 2023-04-29)Climate change alters relationships among environmental conditions and thus has the potential to change the selection pressures acting on adaptive gene variants. Using a landscape genomic approach, we show that the southern ... -
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 ... -
Variación altitudinal de caracteres fenológicos y crecimiento inicial en condiciones controladas entre poblaciones de Nothofagus pumilio provenientes del Centro-Oeste de Chubut, Argentina
(Facultad de Ciencias Forestales y Recursos Naturales de la Universidad Austral de Chile, 2019-02-19)Se estudió la diferenciación altitudinal de seis poblaciones naturales argentinas de lenga (Nothofagus pumilio) del Centro Oeste de la Provincia de Chubut (42° 50´ S) distribuidas en un rango altitudinal de 500 m (1.000 ...
