Anthropogenic Impacts Allowed for the Invasion of Understory Species, Affecting the Sustainability of Management Practices in Southern Patagonia
(MDPI, 2024-01-16)Forest management aims to preserve integrity and ecosystem resilience. Conservation and species invasion patterns must be determined in managed landscapes. The objectives of this study were to identify proxies that allowed ... -
Aprovechamiento y conservación del bosque nativo de lenga
(EEA Santa Cruz, INTA, 2008-06)El bosque nativo de lenga brinda bienes y servicios ambientales, además de sustentar el desarrollo de la cadena de valor maderera de la región. Por lo tanto, las modalidades de uso deben de tener en cuenta criterios de ... -
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 ... -
Calidad de agua en ríos asociados a uso silvopastoril de Ñire en Patagonia Sur, Argentina.
(Ediciones INTA, 2012-05-09)Teniendo en cuenta que una parte importante de los bosques de Nothofagus antárctica (ñire) está asociada a cursos de agua, y mayoritariamente tiene un uso ganadero, el objetivo del presente trabajo fue evaluar si el uso ... -
Cambio Climático en Patagonia Sur: Escenarios futuros en el manejo de los recursos naturales
(Ediciones INTA, 2012)La biodiversidad asociada a los ecosistemas de Patagonia Sur (Santa Cruz y Tierra del Fuego) es consecuencia de una larga evolución de las especies y de la geografía misma, sin olvidar que la misma está en equilibrio con ... -
Cambios producidos por el manejo silvopastoril en bosques de Nothofagus antarctica de Tierra del Fuego y su comparación con otros ambientes = Changes derived by the silvopastoral management in Nothofagus antarctica forests of Tierra del Fuego compared to other environments
(CIPAV, 2023-10-15)Los sistemas silvopastoriles (SSP) son una opción que promueve el equilibrio entre la producción y la conservación. El objetivo fue determinar cambios producidos por SSP en bosques de Nothofagus antarctica (ñire) comparando ... -
Canopy structure analysis for estimating forest regeneration dynamics and growth in Nothofagus pumilio forests
(Springer, 2011-04-08)Introduction Silviculture systems applied in Nothofagus pumilio forests are based on opening the canopy to stimulate natural regeneration by modifying light and soil moisture. The objective is to evaluate regeneration ... -
Carbon (δ13C) and nitrogen (δ15N) stable isotope composition in plant and soil in Southern Patagonia’s native forests.
(Wiley, 2012-01)Stable isotope natural abundance measurements integrate across several biogeochemical processes in ecosystem N and C dynamics. Here, we report trends in natural isotope abundance (d13C and d15N in plant and soil) along a ... -
Carbon accumulation along a stand development sequence of Nothofagus antarctica forests across a gradient in site quality in Southern Patagonia
(Elsevier, 2010-06-25)Above- and below-ground C pools were measured in pure even-aged stands of Nothofagus antarctica (Forster f.) Oersted at different ages (5–220 years), crown and site classes in the Patagonian region. Mean tissue C concentration ... -
Carbon pool dynamics after variable retention harvesting in Nothofagus pumilio forests of Tierra del Fuego
(Springer Nature, 2023-01-23)Background It is necessary to determine the implications for managing forest stands using variable retention harvesting for maintaining carbon and for calculating the effects of different harvesting practices on above‑ and ... -
Carbon Sequestration in Temperate Silvopastoral Systems, Argentina
(Springer, 2018-01)Silvopastoral systems (SPS) provide a wide range of non-provisioning ecosystem services including carbon (C) sequestration. Well-managed SPS outperform both grasslands/pastures and forests in terms of C by increasing soil ... -
