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. ... -
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 ... -
Correlations between physical and chemical defences in plants: tradeoffs, syndromes, or just many different ways to skin a herbivorous cat?
(Wiley, 2013-04)Most plant species have a range of traits that deter herbivores. However, understanding of how different defences are related to one another is surprisingly weak. Many authors argue that defence traits trade off against ... -
Invasions: the trail behind, the path ahead, and a test of a disturbing idea
(Wiley, 2012-01)We provide a brief overview of progress in our understanding of introduced plant species. Three main conclusions emerge from our review: (i) Many lines of research, including the search for traits that make species good ... -
Knowledge arising from long-term research of variable retention harvesting in Tierra del Fuego: where do we go from here?
(Springer Open, 2019-07)Nothofagus pumilio forests in Tierra del Fuego are the southernmost forests in the world, where extreme climate conditions represent a challenge to attain sustainable forest management. Retention forestry was proposed as ... -
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. ... -
Plasticidad ecofisiológica de plántulas de Nothofagus pumilio frente a combinaciones de niveles de luz y humedad en el suelo
(Asociación Argentina de Ecología, 2011)Las propuestas silvícolas para el manejo de los bosques de Nothofagus pumilio se basan sobre la apertura del canopeo para estimular el crecimiento de la regeneración natural; de esta manera se incrementa la disponibilidad ... -
Modelos forzados y no forzados para el cálculo del índice de sitio en bosques de Nothofagus antarctica en Patagonia Sur = Constrained and non-constrained models for site index estimation in Nothofagus antarcticaforests of South Patagonia
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2011)El potencial de producción de un rodal puede definirse a través de la calidad de sitio. Una forma de medir dicha calidad es a través de ecuaciones de índice de sitio, existiendo distintos tipos de ecuaciones (forzadas y ... -
Aspectos ecológicos de la regeneración por semillas en bosques nativos de Nothofagus antarctica en Patagonia Sur, Argentina = Ecological aspects of regeneration from seeds of Nothofagus antarctica native forest in Southern Patagonia, Argentina
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2011)Los objetivos de este estudio fueron cuantificar la producción anual de semillas y su viabilidad germinativa en rodales puros de Nothofagus antarctica (ñire) desarrollándose en tres calidades de sitio, y evaluar el ... -
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 ... -
Suitable conditions for natural regeneration in variable retention harvesting of southern Patagonian Nothofagus pumilio forests
(SpringerOpen, 2019-06)Background: Variable retention (aggregated and dispersed retention) harvesting proposed for Nothofagus pumilio was designed for timber purposes and biodiversity conservation. Harvesting by opening canopy generates different ... -
Modeling soil nitrogen content in South Patagonia across a climate gradient, vegetation type, and grazing
(MDPI, 2019-05)Soil total nitrogen (N) stock in rangelands, shrublands, and forests support key ecological functions such as the capacity of the land to sustain plant and animal productivity and ecosystem services. The objective of this ... -
Potential biodiversity map of understory plants for Nothofagus forests in Southern Patagonia: Analyses of landscape, ecological niche and conservation values
(Elsevier, 2019-09)The role of understory plants in native forests is critical for ecosystem function, wildlife protection and ecosystem productivity. The interest to estimate biodiversity increased during the last decades at landscape level. ... -
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 ... -
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 ... -
Agroforestry landscapes and global change: landscape ecology tools for management and conservation
(Springer, 2012-07)Forest ecosystems are impacted by multiple uses under the influence of global drivers, and where landscape ecology tools may substantially facilitate the management and conservation of the agroforestry ecosystems. The use ... -
Carbon isotopic signatures of soil organic matter correlate with leaf area index across woody biomes
(Wiley, 2014-11)Leaf area index (LAI), a measure of canopy density, is a key variable for modelling and understanding primary productivity, and also water use and energy exchange in forest ecosystems. However, LAI varies considerably with ... -
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 ... -
