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 ... -
Remotely‐sensed primary productivity shows that domestic and native herbivores combined are overgrazing Patagonia
(Wiley; British Ecological Society, 2019-04)1.Carrying capacity is the maximum animal density an area can sustain without deterioration of its resources. Overgrazing has degraded Patagonia, but sheep stocks decreased and gave way to mixed systems with cattle, goats ... -
Rendimiento de distintos sistemas de aprovechamiento en la corta de protección de un bosque de Nothofagus pumilio = Stocking and yield potential of three different logging systems in a shelterwood cut of Nothofagus pumilio forest
(2017)Los bosques de Nothofagus pumilio constituyen la masa forestal de mayor importancia económica del sur de Argentina y Chile. Las existencias de volumen total y el rendimiento volumétrico varían de acuerdo a la calidad de ... -
Reply to: Data do not support large-scale oligotrophication of terrestrial ecosystems.
(Springer Nature, 2019-07-22)Hiltbrunner et al. apply a reductionist approach to argue that the evidence for widespread terrestrial oligotrophication2 should be replaced with a two-factor explanation (growth dilution and depositional signatures) that ... -
Respuesta de la vegetación al manejo por corte en fajas en un arbustal de Mulguraea tridens en Patagonia sur
(2016-12)En Santa Cruz, aproximadamente 2.83 millones de hectáreas conforman el matorral de mata negra, una estepa arbustiva dominada por el arbusto Mulguraea tridens, donde la ganadería ovina extensiva es la principal actividad ... -
Restauración por recolonización de especies nativas en pasturas sembradas en ambientes semiáridos en Patagonia
(Facultad de Agronomía, Universidad Nacional de La Pampa, 2023-06-05)En Patagonia austral el sobrepastoreo provoca cambios irreversibles en los pastizales. La sucesión secundaria en pasturas comerciales podría promover parcialmente la recuperación de especies nativas. Se estudiaron lotes ... -
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 ... -
Seed fall and leaf litter relationships in Nothofagus pumilio forests: changes according to retention levels and years after harvesting
(Springer, 2023-04)Seed fall and leaf litter influence forest regeneration, nutrient cycling, and other key ecological processes closely related to forest management. In Patagonian forests, variation of both managed and unmanaged forests ... -
Sensitivity of global soil carbon stocks to combined nutrient enrichment
(Wiley, 2019-06)Soil stores approximately twice as much carbon as the atmosphere and fluctuations in the size of the soil carbon pool directly influence climate conditions. We used the Nutrient Network global change experiment to examine ... -
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 ... -
Silvopastoral use of Nothofagus antarctica forests in Patagonia: impact on soil microorganisms
(Springer, 2022-09-06)Soil microorganisms contribute to soil carbon storage, soil respiration and nutrient cycling. In south Patagonia, there are scarce studies on carbon (C) and nitrogen (N) in soil microbial biomass (MB). The aim of this work ... -
Silvopastoral use of Nothofagus antarctica in Southern Patagonian forests, influence over net nitrogen soil mineralization
(2013-04)In most temperate forest, nitrogen (N) is considered a limiting factor. This becomes important in extreme environments, as Nothofagus antarctica forests, where the antecedents are scarce. Thinning practices in N. antarctica ... -
Situación de Fasciola hepatica al sur del paralelo 48º S
(2014-03)La fasciolosis, enfermedad cosmopolita, produce importantes pérdidas económicas en la producción ganadera. En Argentina se considera que el límite sur de presentación de Fasciola hepatica (Fh) es el paralelo -48º. El ... -
Soil carbon is a useful surrogate for conservation planning in developing nations
(Nature Research, 2019-03)Defining the optimal placement of areas for biodiversity conservation in developing nations remains a significant challenge. Our best methods for spatially targeting potential locations for biodiversity conservation rely ... -
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 ... -
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 ... -
Soil Nitrate Profiles and the Risk of Nitrate Leaching in Sweet Cherry Orchards Subjected to Different Management Schemes
(2014)When nitrogen is applied to sweet cherry orchards, losses can take place. The authors determined the soil nitrate distribution in fertilized sweet cherry orchards in Southern Patagonia (Argentina). The treatments were ... -
Soil organic carbon stocks in native forest of Argentina: a useful surrogate for mitigation and conservation planning under climate variability
(Springer Nature, 2024-01-05)Background The nationally determined contribution (NDC) presented by Argentina within the framework of the Paris Agreement is aligned with the decisions made in the context of the United Nations Framework Convention on ... -
Soil respiration in Patagonian semiarid grasslands under contrasting environmental and use conditions
(Elsevier, 2015-08)Grasslands comprise 85% of Southern Patagonia land area and play a critical role in the global carbon cycle. We evaluated seasonal dynamics to identify differences in soil respiration rates between contrasting grasslands ... -
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 ...
