En este trabajo se analizó ... -
Drought intensity and duration interact to magnify losses in primary productivity
(American Association for the Advancement of Science (AAAS), 2025-10-16)As droughts become longer and more intense, impacts on terrestrial primary productivity are expected to increase progressively. Yet, some ecosystems appear to acclimate to multiyear drought, with constant or diminishing ... -
Degradation of soil microbiome and carbon dynamics in response to overgrazing in Austral wetland ecosystems
(Elsevier, 2025-12)Wetlands (mallines) of Southern Patagonia are key ecosystems for biodiversity, forage production, and carbon (C) sequestration. However, overgrazing threatens their ecological integrity, causing varying levels of degra ... -
Evaluación de aguas y tierras para la irrigación en el sur de Santa Cruz (Patagonia Austral continental, Argentina)
(Red Argentina de Salinidad, 2025-07-30)En años recientes, el sur de la provincia de Santa Cruz ha experimentado una presión extractiva creciente de agua superficial para el riego extensivo de planicies aluviales, destinado a incrementar la producción de pastizales ... -
Evaluación de distintos tipos de luces para la producción de acelga (Beta vulgaris) en un sistema hidropónico Indoor
(Universidad Nacional de la Patagonia Austral, 2025-10-08)La producción hortícola en regiones de clima extremo, como Río Gallegos, enfrenta desafíos debido a las bajas temperaturas, suelos poco fértiles y escasez de luz natural en invierno. En este contexto, los sistemas hidropónicos ... -

(Bellas Alas Editorial, 2025-10-08)En varias regiones de nuestro país, los fuegos de vegetación son utilizados en la producción agropecuaria para regular el exceso de biomasa de plantas leñosas, mejorar la productividad y calidad nutritiva de los pastizales, ... -
Dynamics of above- and below-ground biomass and nutrient accumulation in an age sequence of Nothofagus antarctica forest of Southern Patagonia
(Elsevier, 2006-07-27)Nothofagus antarctica (Forster f.) Oersted is a deciduous tree species, which naturally grows on poorly drained or drier eastern sites in the Andes Mountain near Patagonian steppe. Above- and below-ground biomass and ... -
Validation of a canopy photosynthesis model for cocksfoot pastures grown under different light regimes
(Springer Nature, 2006-07)Daily net canopy photosynthesis (Pn) was predicted for cocksfoot (Dactylis glomerata L.) canopies grown under different light regimes by integration of a leaf photosynthesis model developed for the light-saturated ... -
Harvesting adaptation to biodiversity conservation in sawmill industry: Technology innovation and monitoring program
(Facultad de Economía y Negocios, Universidad Alberto Hurtado, 2007-09-13)Social demands related to native forest ecosystems are based on an efficient management, with a balance between conservation and timber production. This paper describes the industry adaptation to a biodiversity program ... -
Photosynthetic plasticity of Nothofagus pumilio seedlings to light intensity and soil moisture
(Elsevier, 2007-05-31)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 ... -
Measuring sustainable forest management in Tierra del Fuego, Argentina
(Taylor & Francis, 2007)The Tierra del Fuego government has a statutory responsibility to ensure that Nothofagus forests are sustainably used. To provide strategies to maximize the forest's sustainable benefits for society, this research develops ... -
Morphological, anatomical, and physiological changes of orchardgrass leaves grown under fluctuating light regimes
(Wiley, 2007-11)The physiological and anatomical adaptability of pastures growing under trees in silvopastoral systems can alter the efficiency of conversion of energy to dry matter (DM). This study was conducted to determine the effects ... -
Dry matter production, morphology and nutritive value of Dactylis glomerata growing under different light regimes
(Springer Nature, 2007-02-11)Plant growth, morphology and nutritive value under shade can differ between temperate grasses. Therefore, the aim of this study was to quantify the dry matter (DM) production, sward morphology, crude protein (CP%), organic ... -
