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 ... -
Biodiversity and ecological long-term plots in Southern Patagonia to support sustainable land management: The case of PEBANPA network
(2016-12)Historically, interactions and trends between biodiversity, ecosystem function (EF) and land use practices in southern Patagonia (Argentina) have been largely undocumented and poorly understood. Since 2002, 1214 permanent ... -
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 ... -
When we cannot have it all: Ecosystem services trade-offs in the context of spatial planning
(2017)Spatial planning has to deal with trade-offs between various stakeholders’ wishes and needs as part of planning and management of landscapes, natural resources and/or biodiversity. To make ecosystem services (ES) trade-off ... -
Influencia de factores bióticos y abióticos en el crecimiento de la regeneración pre- y post-cosecha en un bosque de Nothofagus pumilio
(2017)Para definir nuevas prácticas silvícolas es necesario conocer los procesos ecosistémicos involucrados y los impactos que generan. Las propuestas implementadas generaron diversos interrogantes relacionados al dosel remanente, ... -
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 ... -
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 ... -
The database of the PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems) project
(Wiley, 2017-01-05)The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)—has collated from published studies a large, reasonably representative database of comparable samples ... -
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 ... -
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 ... -
Intra-population variability in the drought response of a beech (Fagus sylvatica L.) population in the southwest of Europe
(2017-06)Phenotypic variability within forest species populations is considered of special relevance for local adaptation under new environments, albeit it has been analyzed to a lesser extent than inter-population phenotypic ... -
Microorganismos del suelo en bosques de ñire en Patagonia Sur: resultados preliminares.
(Instituto Forestal (INFOR), 2017-08)Nothofagus antarctica (ñire) es una especie nativa del bosque andino-patagónico que se extiende desde los 36º 30’ hasta los 56º 00’ LS. Es la segunda especie en importancia de la provincia de Santa Cruz, Argentina. En estos ... -
Masting has different effects on seed predation by insects and birds in antarctic beech forests with no influence of forest management
(2017-09-15)Mast seeding is characteristic of many long-lived tree species and widely proposed as a mechanism to reduce seed predation. However, whether the efficiency of this reproductive response may vary depending on type of seed ... -
Physico-chemical properties of plant cuticles and their functional and ecological significance
(2017-11)Most aerial plant surfaces are covered with a lipid-rich cuticle, which is a barrier for the bidirectional transport of substances between the plant and the surrounding environment. This review article provides an overview ... -
Thinking in the sustainability of Nothofagus antarctica silvopastoral systems, how differ the responses of seedlings from different provenances to water shortage?
(2017-12)Nothofagus antarctica, is the most important species of the silvopastoral systems of southern Patagonia. However, there is limited information on the ecophysiological response mechanisms of seedlings for survival under ... -
The role of facultatively nectarivorous birds as pollinators of Anarthrophyllum desideratum in the Patagonian steppe: a geographical approach
(2017-12)The endemic shrub Anarthrophyllum desideratum appears to be the only ornithophilous plant offering nectar as reward in the extensive Patagonian steppe. The identity of its floral visitor assemblage and to what extent this ... -
