Rangeland grazing management in Argentine Patagonia
(IJAB. Friends science publishers, 2020-08-31)Stocking rate adjustment in grazing management is recommended as a management tool to sustain productivity and improve soil health of permanent grassland ecosystems. The aim of this project was to assess the effect of ... -
Raspberries and gooseberries in south Patagonia: Production, fruit quality, morphology and phenology in two environmental conditions
(Elsevier, 2019)Fine fruits as raspberry and gooseberries represent the second production with the largest area cultivated in Santa Cruz province (Argentina), and this activity is usually carried out by family farmers in outdoor conditions. ... -
Recent deforestation drove the spike in Amazonian fires
(IOP Publishing, 2020-12-11)Tropical forests are of global importance even though they only cover around 10% of the Earth's land surface. They store large amounts of carbon and host between one-half and two-thirds of the world's species (Lewis 2006). ... -
REDD+ en Latinoamérica: el caso de Perú
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2013)La cuestión de cómo los países en vías de desarrollo como el Perú pueden participar efectivamente en el marco REDD+ (reducción de emisiones de la deforestación y degradación de bosques) de las Naciones Unidas ha sido el ... -
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 ... -
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 ... -
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 ... -
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 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 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 ...
