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 ... -
Above- and below-ground nutrient tissue concentration and leaf pigment changes in Patagonian woody seedlings grown under light and soil moisture gradients
(Taylor & Francis, 2011-10-28)To understand the ecophysiology of natural regeneration above- and below-ground nutrient tissue concentration and leaf pigment changes in Nothofagus pumilio (lenga) seedlings grown in three light intensities (4%, 26% and ... -
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 ... -
La Agricultura familiar en Santa Cruz, Patagonia Argentina : caracterización de los núcleos agrícolas familiares
(Universidad Nacional de la Patagonia Austral (UNPA), 2020-11-13)La agricultura familiar abarca a un grupo grande de personas que tienen distintos orígenes y una amplia diversidad cultural, pero que mantienen en común la producción de alimentos como forma de vida. El objetivo del presente ... -
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 ... -
Allometric relations for biomass partitioning of Nothofagus antarctica trees of different crown classes over a site quality gradient
(Elsevier, 2010-03)Data on tree biomass are essential for understanding the forest carbon cycle and plant adaptations to the environment. We determined biomass accumulation and allometric relationships in the partitioning of biomass between ... -
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 ... -
Are Patagonia grasslands being overgrazed? A response to Marino et al. (2020)
(Wiley, 2020-09)Based upon primary productivity estimates, Oliva et al. (2019) concluded that, at the end of last century and after long periods of overgrazing, Patagonia's domestic stocks adjusted to regional‐scale herbivore carrying ... -
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 ... -
Assessing Knowledge Production for Agrosilvopastoral Systems in South America
(2018-02)In recent decades agroforestry has undergone significant development in Latin America. South America generates the most scientific research on the topic in the region. We conducted a comprehensive review and analysis of ... -
BAAD: A biomass and allometry database for woody plants.
(Ecological Society of America, 2015-05-01)Understanding how plants are constructed—i.e., how key size dimensions and the amount of mass invested in different tissues varies among individuals—is essential for modeling plant growth, carbon stocks, and energy fluxes ... -
Better estimates of soil carbon from geographical data: a revised global approach
(2018-05)Soils hold the largest pool of organic carbon (C) on Earth; yet, soil organic carbon (SOC) reservoirs are not well represented in climate change mitigation strategies because our database for ecosystems where human impacts ... -
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 ... -
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 ... -
Biomasa y respiración microbiana : respuesta ante cambios en la humedad del suelo en la Estepa Magallánica Seca de Santa Cruz, Argentina
(Universidad Nacional de la Patagonia Austral (UNPA), 2020-11-17)El carbono y el nitrógeno de la biomasa microbiana (CBM y NBM) del suelo son bioindicadores que tienen el potencial de mostrar cambios en el suelo de los ecosistemas, y están condicionados por la humedad disponible en el ... -
Biomass, carbon and nutrient storage for dominant grasses of cold temperate steppe grasslands in southern Patagonia, Argentina
(Elsevier, 2010-01)We hypothesized that different dominant grasses species display contrasting nutrient accumulation, allocation and conservation strategies. Also, we expect a distinctive pattern of carbon and biomass partitioning according ... -
Biophysical and socioeconomic factors influencing soil carbon stocks: a global assessment
