Proposals for Nothofagus antarctica diameter growth estimation: simple vs. global models
(Czech Academy of Agricultural Sciences, 2014)Tree growth is one of the main variables needed for forest management planning. The use of simple models containing traditional equations to describe tree growth is common. However, equations that incorporate different ... -
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. ... -
State and transition model approach in native forests of Southern Patagonia (Argentina): linking ecosystem services, thresholds and resilience
(Taylor & Francis, 2017-04)The sustainable use of ñire forests requires knowledge of its dynamics and management to maintain long-term main forest ecosystem services. The aim of this work was to develop a structural–functional state and transition ... -
Monitoring drylands: The MARAS system
(Elsevier, 2018-11-09)MARAS (Monitoring of Arid and Semiarid Regions) consists of 379 ground monitors in Patagonia, a 624.500 km2 semiarid area of southern Argentina and Chile. The objective of this paper was to describe the system and analyze ... -
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 ... -
Are silvopastoral systems compatible with forest regeneration? An integrative approach in southern Patagonia
(2013-12)We used an integrated approach to analyze the influence of silvopastoral management on the biotic and abiotic factors influencing on the natural recruitment of native forests in Tierra del Fuego (Argentina). The probabilities ... -
Biodiversity potential of Nothofagus forests in Tierra del Fuego (Argentina): tool proposal for regional conservation planning
(2016-09)It is difficult to map and quantify biodiversity at landscape level in areas with low data availability, despite demand from decision-makers. We propose a methodology to determine potential biodiversity pattern using habitat ... -
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 ... -
Why biodiversity increases after variable retention harvesting: A meta-analysis for southern Patagonian forests
(2016-06-01)Effects of forest harvesting on biodiversity can be varied and complex to understand. We provide a meta-analysis of 553 studies plants, insects and birds to identify the general responses to Variable Retention harvesting ... -
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 ... -
Condiciones de suelo y vegetación en tres bosques quemados de Nothofagus pumilio en Argentina y experiencias para su restauración activa
(2018-08)El fuego es un disturbio importante en bosques de lenga de Chubut y Santa Cruz, en la Patagonia argentina. Según del tipo de bosque y la severidad del fuego, el sistema resultante puede diferir en gran medida respecto del ... -
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 ... -
Survival and growth of Nothofagus pumilio seedlings under several microenvironments after variable retention harvesting in southern Patagonian forests
(INRA : Springer, 2014)Context: Variable retention prescriptions for Nothofagus pumilio forests provide for biodiversity conservation and natural regeneration by controlled opening of the canopy. Harvesting generates different microenvironments ... -
The effects of land management (grazing intensity) vs. the effects of topography, soil properties, vegetation type, and climate on soil carbon concentration in Southern Patagonia
(Elsevier, 2016-11)Grazing is an economically important activity in Southern Patagonia’s steppe and woodland ecosystems. In the past, emphasis has been on maximizing the provisioning capacity of these ecosystems with little concern for the ... -
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 ... -
Mistletoes and epiphytic lichens contribute to litter input in Nothofagus antarctica forests
(Elsevier, 2015-10)Litter input is one of the key components that define nutrient cycling in forests and the majority of studies only consider the tree components of litterfall. However, epiphytic species can play a crucial role in litter ... -
Spatial patterns of cultural ecosystem services provision in Southern Patagonia
(Springer, 2016-02)Context Although there is a need to develop a spatially explicit methodological approach that addresses the social importance of cultural ecosystem services for regional planning, few studies have analysed the spatial ... -
Above-ground arthropod community structure and influence of structural-retention management in southern Patagonian scrublands, Argentina
(Springer, 2016-12)Southern Patagonia’s landscape hosts several semi-natural habitats, traditionally used for sheep production, such as Mulguraea tridens and Lepidophyllum cupressiforme scrublands. Mulguraea scrublands are managed via ... -
Modeling of potential habitat suitability of Hippocamelus bisulcus: effectiveness of a protected areas network in Southern Patagonia
(Springer, 2017)Introduction Huemul (Hippocamelus bisulcus Molina) is the most threatened flag species of Southern Patagonia, where conservation efforts were not effective to avoid the retraction of its distribution area. Habitat quality ... -
