Lamb and wool provisioning ecosystem services in Southern Patagonia
(MDPI, 2021-07-30)In Southern Patagonia, grasslands are the principal food resource for sheep reared for meat and wool as the main provisioning ecosystem services (ES). The main objective of this study was to model lamb and wool production ... -
Land sharing in South Patagonia: Conservation of above-ground beetle diversity in forests and non-forest ecosystems
(Elsevier, 2019-11)Land-sharing strategies, as variable retention silvicultural proposals, are useful to mitigate harmful effects of economic activities on forest biodiversity; benefits have been reported worldwide for several organisms. ... -
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 ... -
Landscape variables influence over active restoration strategies of Nothofagus forests degraded by invasive Castor canadensis in Tierra del Fuego
(MDPI, 2021-07-06)North American beavers (Castor canadensis) are responsible for the major changes in the Tierra del Fuego Archipelago, altering riparian forests for the long-term. Passive restoration of the areas affected was ineffective ... -
Leaf and canopy photosynthesis models for cocksfoot (Dactylis glomerata L.) grown in a silvopastoral system
(Lincoln University, Nueva Zelanda, 2002)The aim of the research reported in this thesis was to construct leaf and canopy photosynthesis models for understorey cocksfoot pasture grown in a 10-11-year old Pinus radiata silvopastoral system. From these models, dry ... -
Leaf nutrients, not specific leaf area, are consistent indicators of elevated nutrient inputs
(Nature Research, 2019)Leaf traits are frequently measured in ecology to provide a ‘common currency’ for predicting how anthropogenic pressures impact ecosystem function. Here, we test whether leaf traits consistently respond to experimental ... -
Leaf wettability, anatomy and ultra-structure of Nothofagus antarctica and N. betuloides grown under a CO2 enriched atmosphere
(Elsevier, 2023-01)Increasing CO2 air concentration may affect wettability, anatomy and ultra-structure of leaves of Patagonian forest species, evergreen and deciduous plants potentially responding differently to such CO2 increases. In this ... -
Linking changes in species composition and biomass in a globally distributed grassland experiment
(Wiley, 2022-11-24)Global change drivers, such as anthropogenic nutrient inputs, are increasing globally. Nutrient deposition simultaneously alters plant biodiversity, species composition and ecosystem processes like aboveground biomass ... -
Linking potential biodiversity and three ecosystem services in silvopastoral managed forest landscapes of Tierra del Fuego, Argentina
(Taylor & Francis, 2017-04)Several studies confirm that biodiversity loss endangers ecosystem services (ES) supply and human well-being. A better understanding of biodiversity–ES relationships and effects of biodiversity loss on ES supply is needed. ... -
Linking species distribution and territorial planning to the management of the endangered Gonopterodendron sarmientoi in native forests of the Chaco region, Argentina
(Elsevier, 2022-06-11)For management and conservation strategies in the long term is necessary to know the species distribution and main biophysical aspects that determine the structure and dynamics of the forest. The aim of this work was to ... -
Listado florístico, estado de conservación, y unidades de vegetación de Isla Valdés, Parque Interjurisdiccional Marino Costero Patagonia Austral (Chubut, Argentina)
(Sociedad Argentina de Botánica, 2024-05)Introducción y objetivos: El Parque Interjurisdiccional Marino Costero Patagonia Austral es un área protegida que alberga una gran biodiversidad. Dentro del Parque se encuentra Isla Valdés, isla de la cual se desconoce su ... -
Litter decomposition and nutrients dynamics in Nothofagus antarctica forests under silvopastoral use in Southern Patagonia.
(Springer, 2012-01-24)The role of environmental variables on litter decomposition and its nutrient release in Nothofagus antarctica forest in Patagonia is poorly understood. Moreover, in these forests under silvopastoral use there are few ... -
Litterfall and nutrients return in Nothofagus antarctica forests growing in a site quality gradient with different management uses in Southern Patagonia
(2015-01)We evaluated the annual litterfall and nutrients return in primary forests of Nothofagus antarctica growing at three different site classes (SC) (III, IV and V) and compared two of these forests with adjacent stands under ... -
Línea de base para el monitoreo de manejo silvopastoril con separación de ambientes = Baseline to monitoring silvopastoral management using vegetation type separation
(Ediciones INTA, 2018-10-31)Una línea de base constituye un punto de referencia con el cual comparar y detectar cambios en el tiempo según el manejo que se haga del área de interés. La implementación de nuevos esquemas productivos (ej., manejo ... -
Long-term monitoring of thinning for silvopastoral purposes in Nothofagus antarctica forests of Tierra del Fuego, Argentina
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, España, 2018)Aim of the study: To analyse the effectiveness of thinning on tree growth, forest structure and microclimatic variables along seven years after cuttings in a secondary Nothofagus antarctica forest in Southern Patagonia. Area ... -
Macho Entero Joven, una nueva categoría eficiente en bovinos
(EEA Chubut, INTA, 2020-11)En Argentina, el Ministerio de Agricultura, Ganadería y Pesca de la Nación estableció en el año 2010 la creación de una nueva categoría bovina para la faena denominada Macho Entero Joven (MEJ), animal con testículos con ... -
Mallines del sur de la patagonia: interacciones entre unidades fisiográficas y productividad en diversos ambientes geomorfológicos
(Edición del Autor, 2017)Esta investigación surge con el propósito comprender el rol que ejercen las condiciones de emplazamiento en los mallines del Sur de la Patagonia, así como analizar sus características hidro-eco-geomorfológicas, su interacción ... -
Manejo adaptativo de los pastizales : del concepto a la práctica
(2016)El pastoreo directo de estepas y mallines representa la base nutricional para la ganadería en Patagonia. Una característica común de estos ambientes es la gran variabilidad de su productividad entre años.
