Thinking in the sustainability of Nothofagus antarctica silvopastoral systems, how differ the responses of seedlings from different provenances to water shortage?
(2017-12)Nothofagus antarctica, is the most important species of the silvopastoral systems of southern Patagonia. However, there is limited information on the ecophysiological response mechanisms of seedlings for survival under ... -
Intra-population variability in the drought response of a beech (Fagus sylvatica L.) population in the southwest of Europe
(2017-06)Phenotypic variability within forest species populations is considered of special relevance for local adaptation under new environments, albeit it has been analyzed to a lesser extent than inter-population phenotypic ... -
The relative importance of soil properties and regional climate as drivers of productivity in southern Patagonia’s Nothofagus antarctica forests
(2018-06)Soil texture and temperature-related variables were the variables that most contributed to Nothofagus antarctica forest height in southern Patagonia. This information may be useful for improving forest management, for ... -
Modelling soil carbon content in south Patagonia and evaluating changes according to climate, vegetation, desertification and grazing
(2018)In Southern Patagonia, a long-term monitoring network has been established to assess bio-indicators as an early warning of environmental changes due to climate change and human activities. Soil organic carbon (SOC) content ... -
Herbivores safeguard plant diversity by reducing variability in dominance
(2018-01)Reductions in community evenness can lead to local extinctions as dominant species exclude subordinate species; however, herbivores can prevent competitive exclusion by consuming otherwise dominant plant species, thus ... -
Soil microbial processes in a pine silvopastoral system in NW Patagonia
(2018-02)The conversion of native vegetation to tree plantation (afforestation) implies a drastic change in life forms and as a consequence, changes in the microenvironmental conditions, and the quantity and quality of organic ... -
Cisticercosis visceral por Cysticercus tenuicollis en ovinos de faena en la Provincia de Santa Cruz, Argentina
(2018-03)Durante la zafra 2014-2015 en todos los frigoríficos de la localidad de Río Gallegos, provincia de Santa Cruz, llamó la atención un aumento importante de decomisos de vísceras rojas en corderos, debido a la presencia de ... -
Producción bovina bajo manejo silvopastoril intensivo a escala de establecimiento y ciclo completo en Tierra del Fuego, Argentina = Cattle production under intensive silvopastoral management at ranch level and complete production cycle in Tierra del Fuego, Argentina
(2018)Los sistemas bovinos extensivos de Tierra del Fuego incorporan escasa tecnología de manejo por lo que poseen bajos niveles de producción por unidad de superficie. No obstante, hoy existen tecnologías disponibles como la ... -
When we cannot have it all: Ecosystem services trade-offs in the context of spatial planning
(2017)Spatial planning has to deal with trade-offs between various stakeholders’ wishes and needs as part of planning and management of landscapes, natural resources and/or biodiversity. To make ecosystem services (ES) trade-off ... -
Regeneración por semillas en bosques nativos de Nothofagus antarctica bajo uso silvopastoril en Patagonia Sur, Argentina = Seed regeneration in native forests of Nothofagus antarctica under silvopastoral use in Southern Patagonia, Argentina
(2013-03)Los objetivos de este estudio fueron: i) evaluar la regeneración, desde el punto de vista de su producción y calidad de semillas, así como también de la instalación y supervivencia de plántulas, de dos rodales puros de ... -
Natural dynamics and thinning response of young lenga [Nothofagus pumilio] trees in secondary forests of Southern Patagonia = Dinámica natural y respuesta al raleo de árboles juveniles de lenga (Nothofagus pumilio) en bosques secundarios en Patagonia Sur
(2013)For saw-log production, planned thinning in secondary forests may reduce the time to yield products of a desired size and quality. To explore some options, long-term monitoring plots were established in 1996 in two secondary ... -
Partición diferencial de nutrientes en arboles de Nothofagus antarctica creciendo en un gradiente de calidades de sitio en Patagonia Sur = Different nutrient allocation in Nothofagus antarctica trees growing over a site quality gradient in South Patagonia
(2013)Nothofagus antarctica (ñire) es una especie nativa caducifolia que crece al sur de Argentina y Chile. Estudiar la distribución de nutrientes en árboles es importante como base para el entendimiento de la dinámica de los ... -
Landscape heterogeneity influences on sheep habits under extensive grazing management in Southern Patagonia
(2015)In Southern Patagonia, continuous grazing with fixed stocking rates in large paddocks prevails over grazing systems subjected to regular evaluations and rotational rests. Because of this, sheep extensive systems need ... -
Convergence of soil nitrogen isotopes across global climate gradients
(2015-02-06)Quantifying global patterns of terrestrial nitrogen (N) cycling is central to predicting future patterns of primary productivity, carbon sequestration, nutrient fluxes to aquatic systems, and climate forcing. With limited ... -
