Timber management with variable retention in Nothofagus pumilio forests of Southern Patagonia

Forest Ecology and Management, 2009
Abstract Forestry practices integrating ecological and social criteria have been replacing those based only on economic values. Traditional silviculture, such as shelterwood cuts (SC), transforms uneven-aged original stands to an even-aged managed forest.

Transition of plasmodium sporozoites into liver stage-like forms is regulated by the RNA binding protein pumilio [PDF]

, 2011
Many eukaryotic developmental and cell fate decisions that are effected post-transcriptionally involve RNA binding proteins as regulators of translation of key mRNAs.

Photosynthetic plasticity of Nothofagus pumilio seedlings to light intensity and soil moisture

Forest Ecology and Management, 2007
Abstract Nothofagus seedlings often survive and grow slowly for a long time in the shaded understory. This creates a seedling bank with a potential advantage in reestablishing canopy disturbances. To manage primary forests more effectively, it is important to understand the basis of plant regeneration ecophysiology, and their plasticity to changes in

Timber harvesting and wildfires drive long-term modification in forest structure of Nothofagus pumilio: resilience characterization based on disturbance legacies

Ecological Processes
Background Natural forests are intrinsically resilient to natural disturbances but can be vulnerable to anthropogenic impacts (e.g. wildfires and harvesting).

Urbanization and Seasonality Increase Introduced Plant Consumption by the World's Southernmost Parrot 城市化与季节性增加了全球最南端鹦鹉对引入植物的取食

Integrative Conservation, Volume 5, Issue 1, Page 86-103, March 2026.
Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...

Fraccionamiento y recuperación de proteínas solubles libres de fenoles en estacas de lenga (Nothofagus pumilio) [PDF]

, 2006
At present, there is no information about Nothofagus fractioning and protein recovery from cutting crude extracts; necessary condition to, in vitro, demonstrate enzymatic activity with cofactors presence. Besides, this information is crucial to determine

Essential Nutrient and Trace Element Foliar Resorption of Two Co-Existing Nothofagus Species Grown Under Different Environmental Conditions in Southern Patagonia

Frontiers in Plant Science, 2019
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.

Desarrollo de los bosques de Lenga (Nothofagus pumilio) después de la corta de regeneración = Development of Nothofagus pumilio forest after a regeneration cut

Ciencia & Investigación Forestal, 2008
En Magallanes los bosques de lenga aptos para la producción de madera son del orden de 500.000 ha. Desde 1991 los bosques que se intervienen se manejan con cortas de protección. Hasta la fecha se han intervenido cerca de 30.000 ha bajo este sistema. En este trabajo se analiza las modificaciones que se producen en los bosques intervenidos a existencias,
