Climate influence seed production in managed and unmanaged Nothofagus pumilio forests of Southern Patagonia
(SCION, 2024-07-24)Background: Annual seed production is key to understand natural forest dynamics and to apply sustainable forest management. This process is subjected to variations according to annual and seasonal climatic conditions, ... -
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 ... -
Establecimiento y producción de forraje de cereales de invierno en la patagonia austral
(Asociación Argentina de Producción Animal, 2020-12)Se realizó un ensayo con el objetivo de evaluar el establecimiento y la producción de forraje para henificación de una variedad y líneas de triticale (X Triticosecale Wittmack), variedades de trigo pan (Triticum aestivum ... -
Evaluación de cereales de invierno en Santa Cruz
(EEA Santa Cruz, INTA, 2016-04-19)En el Sur de Patagonia, una alternativa para mejorar la oferta forrajera de las áreas con mayor potencial consiste en la siembra de cereales de invierno en secano en áreas ecológicas con precipitaciones favorables (350-400 ... -
Evolución del material vivo y muerto y la proteína bruta en pasturas de agropiros y pasto ovillo según el estado fenológico en la Patagonia Austral. Comunicación
(Asociación Argentina de Producción Animal, 2022-11-16)El manejo eficiente del pastoreo y la mejora en la repuesta productiva del ganado en pasturas introducidas de gramíneas en la región requieren del conocimiento sobre las variaciones de las fracciones del forraje cosechado ... -
Métodos de cosecha forestal que combinan conservación de la biodiversidad y los ciclos naturales del bosque primario con la producción maderera en Tierra del Fuego
(Facultad de Ciencias Forestales y de la Conservación de la Naturaleza, Universidad de Chile, 2012)Los bosques de Tierra del Fuego han sido utilizados por los pueblos originarios desde hace miles de años Nothofagus pumilio (lenga) en (Orquera et al., 2012), pero su aprovechamiento a gran escala comenzó con la colonización ... -
Pérdidas por descarte en la cadena de producción de cerezas
(Consejo de los Profesionales del Agro, Alimentos y Agroindustria (CPIA), 2022-09)Desde 2015 la Argentina cuenta con un Plan Nacional de Reducción de Pérdidas y Desperdicio de Alimentos (PDA) y, a partir de 2017, con una Red Nacional para la Reducción de Pérdidas y Desperdicio de Alimentos conformada ... -
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 ... -

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 ... -
Suitable conditions for natural regeneration in variable retention harvesting of southern Patagonian Nothofagus pumilio forests
(SpringerOpen, 2019-06)Background: Variable retention (aggregated and dispersed retention) harvesting proposed for Nothofagus pumilio was designed for timber purposes and biodiversity conservation. Harvesting by opening canopy generates different ... -
