Assessment of provisioning ecosystem services in terrestrial ecosystems of Santa Cruz Province, Argentina.
(Springer, 2021-04-27)Provisioning ecosystem services play an important role in the development of regional economies. Traditional managements usually intensify the supply of provisioning services, without consideration of other services (e.g. ... -
Decomposition and nutrient release of grass and tree fine roots along an environmental gradient in southern Patagonia
(Wiley, 2018-10-25)Decomposition of fine roots is a fundamental ecosystem process that relates to carbon (C) and nutrient cycling in terrestrial ecosystems. However, this important ecosystem process has been hardly studied in Patagonian ... -
Diagnostico socio - productivo de la problemática de deterioro de los pastizales patagónicos en el departamento Tehuelches, provincia de Chubut
(Facultad de Agronomía, Universidad de Buenos Aires, 2015)Desde el inicio de la ganadería ovina en la Patagonia hasta hoy se han generado procesos de deterioro de los pastizales naturales en forma generalizada. Dichos procesos en gran medida están asociados al uso inadecuado por ... -
Diversidad de plantas vasculares en bosques continuos y relictuales de Nothofagus antárctica (Nothofagaceae) en Patagonia austral
(Universidad de Magallanes, Chile, 2019)La historia de los bosques de Nothofagus antarctica (ñire, ñirre) está asociada a profundos disturbios geológicos y climáticos. A éstos se le suman los disturbios más recientes, que junto a los usos culturales de la tierra ... -
Essential Nutrient and Trace Element Foliar Resorption of Two Co-Existing Nothofagus Species Grown Under Different Environmental Conditions in Southern Patagonia
(Frontiers Media, 2019-11)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. Focusing on ... -
Establishing the ecological restoration network in Argentina: from Rio1992 to SIACRE2015
(2015-03)The development of the science and practice of restoration ecology in Argentina can be divided into three periods. The first was 1992–2004, characterized by isolated restoration efforts, mostly in arid and dry ecosystems, ... -
Estado de la vegetación en Santa Cruz y Tierra del Fuego. Primer trimestre 2018
(EEA Santa Cruz, INTA, 2018)En la actualidad, esta tendencia continúa con estado bueno a muy bueno, especialmente durante los meses de enero y febrero, donde predominaron los colores verdes indicando que estos meses fueron más húmedos que el promedio. ... -
Estado de la vegetación en Santa Cruz. Inicio de Primavera (2020)
(EEA Santa Cruz, INTA, 2020-10)En el informe anterior se presentaron los mapas de anomalía de los meses de Febrero, Marzo y la primera quincena del mes de abril del 2020. En los mismos se observó un aumento de las condiciones de sequía (tonos naranjas ... -
Indicadores de receptividad ovina en tres áreas ecológicas de la provincia de Santa Cruz
(Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2010)En Patagonia Sur los cálculos de receptividad ganadera se basan en la estimación de la oferta forrajera de gramíneas bajas. Sin embargo, los arbustos y subarbustos representan hasta el 75% de la PPNA en algunas de las áreas ... -
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 ... -
Microbial processing of plant remains is co‐limited by multiple nutrients in global grasslands
(Wiley, 2020-06)Microbial processing of aggregate‐unprotected organic matter inputs is key for soil fertility, long‐term ecosystem carbon and nutrient sequestration and sustainable agriculture. We investigated the effects of adding multiple ... -
Pastoreo estratégico de ambientes para mejorar la producción ovina en campos del ecotono Bosque-Estepa en Patagonia Sur = Strategic grazing management for better sheep production at the forest-grass steppe ecotone in southern Patagonia
(Asociación Argentina de Producción Animal, 2014-06)El manejo del pastoreo en sistemas ganaderos extensivos con múltiples ambientes se presenta como un desafío dadas las condiciones climáticas y la configuración de los ambientes en los grandes potreros (300-5000 ha) propios ... -
Potential biodiversity map of darkling beetles (Tenebrionidae): environmental characterization, land-uses and analyses of protection areas in Southern Patagonia
(Springer, 2019-07-23)Different methodologies had been developed for species management and conservation based on modelling of potential biodiversity at regional scales. However, most of these models were fitted for umbrella species (e.g. big ... -
Potential biodiversity map of lizard species in Southern Patagonia: environmental characterization, desertification influence and analyses of protection areas
(2018)The distribution of biodiversity at the landscape level is shaped by biotic, abiotic and anthropogenic factors. Biodiversity maps provide the basis for defining management and conservation strategies that can minimize human ... -
Relating water use to morphology and environment of Nothofagus from the world’s most southern forests
(2014-02)A pronounced environmental gradient dictates the dominance of Nothofagus in the foothills on the eastern side of the Andes Mountains in Patagonia, Argentina. Below 50° southern latitude, open forests of Nothofagus antarctica ... -
Retention Forestry in Southern Patagonia: Multiple Environmental Impacts and Their Temporal Trends
(Commonwealth Forestry Association, 2015-06)Harvesting with variable retention (VR) applied in Nothofagus forests combines two types of retention: patches of original forest (aggregates) and single isolated homogeneously distributed trees (dispersed). This study ... -
Sheep faeces decomposition and nutrient release across an environmental gradient in Southern Patagonia
(2017-04)In Southern Patagonia, most of the land ranging from the mountains to the sea in contrasting environmental conditions is devoted to extensive sheep farming. Existing estimations indicate that in ecosystems under livestock ... -
Soil microbial communities respond to an environmental gradient of grazing intensity in south Patagonia Argentina
(Elsevier, 2020)Soil microorganisms communities regulate key functions in terrestrial ecosystems and contributes to the formation of stable organic matter and hence climate change mitigation. The structure, diversity and activity of soil ... -
Spatial heterogeneity in species composition constrains plant community responses to herbivory and fertilisation
(Wiley, 2018-09)Environmental change can result in substantial shifts in community composition. The associated immigration and extinction events are likely constrained by the spatial distribution of species. Still, studies on environmental ... -
