Bird community, forest structure and landscape affects the susceptibility to open-cup nest predation in austral forests
(MDPI, 2025-11-18)Nest predation is a major factor limiting avian reproductive success. It depends on factors such as bird community, land use, vegetation structure and landscape. Anthropogenic disturbances in native forests, such as logging ... -
Drought and Plant Invasions Along an Aridity Gradient
(Wiley, 2025-11-07)Questions: Biological invasions significantly impact plant communities, affecting and threatening biodiversity at regional and local scales worldwide. The invasion process may be influenced by climate change, particularly ... -
Direct drivers of spontaneous exotic plant richness in Southern Patagonia from Argentina
(Springer Nature, 2025-10-21)Purpose of Review In this study, we assess whether exotic plant species richness in southern Patagonia is primarily constrained by environmental adversity, human activity or both. Recent Findings The establishment of exotic ... -
Calidad del agua para irrigación de ríos y arroyos del centro de Santa Cruz (Patagonia Austral Continental, Argentina)
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2025-11-04)Las regiones hidrográficas de los ríos Chico, Chalia y Santa Cruz, en la provincia de Santa Cruz, carecen de antecedentes documentados sobre la aptitud de sus aguas para su utilización en riego. 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 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 ... -
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 ... -
Afidos (Hemiptera. Aphididae) de interés económico en la provincia de Santa Cruz
(Instituto Nacional de Tecnología Agropecuaria, 2007-04)Los pulgones o áfidos (Aphididae), debido a sus características biológicas e impacto económico en los cultivos, representan uno de los grupos de insectos más importantes desde el punto de vista agronómico. Por ello, es de ... -
A Transdisciplinary Framework to Bridge Science–Policy–Development Gaps in Global Land Management Initiatives
(Wiley, 2025-08)Effective implementation of Sustainable Land Management (SLM) remains a major challenge worldwide because of its weak integration within the domains of science, policy, and development practice. Based on global analyses ... -
Effects of land use types and spatial heterogeneity on soil microbial biomass and activity along environmental gradients in Austral ecosystems
(Elsevier, 2025-09)Different land use systems can alter the structure and function of soil microorganisms, affecting microbialmediated processes and potentially undermining consequences for soil fertility and ecosystem health. The effects ... -
