A review of silvopastoral systems in native forests of Nothofagus antarctica in southern Patagonia, Argentina
(2016-12)Silvopastoral systems in Nothofagus antarctica (ñire) forest have become an economical, ecological and productive alternative in Patagonia. Southern Patagonia’s experience over the past 12 years with silvopastoral systems ... -
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 ... -
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 ... -
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 ... -
Biophysical and socioeconomic factors influencing soil carbon stocks: a global assessment
(Springer, 2020-07-24)Soil is the most important terrestrial carbon (C) reservoir but is greatly impacted by land use change (LUC). Previous analyses of LUC impacts on soil C have focused on biophysical variables, leaving aside the influence ... -
Climatic controls of decomposition drive the global biogeography of forest tree symbioses
(Springer Nature, 2019-05-15)The identity of the dominant root-associated microbial symbionts in a forest determines the ability of trees to access limiting nutrients from atmospheric or soil pools1,2, sequester carbon3,4 and withstand the effects of ... -
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 ... -
Conservation values of understory vascular plants in even- and uneven-aged Nothofagus antarctica forests
(Springer, 2020-09)Usually, stands with aging trees are considered forests with higher conservation values, regardless their structural diversity and other functional attributes. Natural stands present a wide range of age structures, from ... -
Effectiveness of fencing and hunting to control Lama guanicoe browsing damage: Implications for Nothofagus pumilio regeneration in harvested forests
(2016-03-01)Browsing damage by native ungulates is often to be considered one of the reasons of regeneration failure in Nothofagus pumilio silvicultural systems. Fencing and hunting in forests at regeneration phase have been proposed ... -
Estimates of soil carbon concentration in tropical and temperate forest and woodland from available GIS data on three continents
(2013-04)Aim: Concern about climate change, with the subsequent emergence of carbonmarkets and policy initiatives such as REDD (reducing carbon emissions bydecreasing deforestation and forest degradation), have focused attention ... -
Improving the knowledge of plant potential biodiversity-ecosystem services links using maps at the regional level in Southern Patagonia.
(Springer, 2021-07-22)Background: Biodiversity supports multiple ecosystem services, whereas species loss endangers the provision of many services and affects ecosystem resilience and resistance capacity. The increase of remote sensing techniques ... -
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, ... -
Interacciones ecológicas en bosques de Nothofagus antarctica bajo uso silvopastoril en Patagonia sur continental
(Asociación Española de Ecología Terrestre, 2018-12)Los bosques de ñire (Nothofagus antarctica) en el sur de Patagonia se ubican mayoritariamente limitando con la estepa. De esta manera, han sido utilizados como sistemas silvopastoriles con ganadería ovina y/o bovina desde ... -
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. ... -
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. ... -
Litterfall and nutrients return in Nothofagus antarctica forests growing in a site quality gradient with different management uses in Southern Patagonia
(2015-01)We evaluated the annual litterfall and nutrients return in primary forests of Nothofagus antarctica growing at three different site classes (SC) (III, IV and V) and compared two of these forests with adjacent stands under ... -
