(Springer, 2008)The genetic control of tree ring growth in Douglas-fir in response to the drought and heat-wave that occurred in 2003 in Europe was studied with microdensity profiles in three clonal experiments located in three different ... -
Genetic diversity and population structure in Nothofagus pumilio, a foundation species of Patagonian forests: defining priority conservation areas and management
(Springer Nature, 2020-11)Patagonian forests are the southernmost temperate forests in the world, and Nothofagus pumilio is one of their most ecologically important tree species (i.e., a foundation species). It presents great adaptability and a ... -
Heritable variation in the survival of seedlings from Patagonian cypress marginal xeric populations coping with drought and extreme cold
(Springer, 2012-01)The rear edges of tree species have begun to be perceived as highly valuable for genetic resources conservation and management. In view of expected climatic changes, the responses of trees at their xeric limits may largely ... -
Integrar disciplinas para el estudio de la respuesta adaptativa de los bosques al cambio climático
(Red Argentina de Ciencia y Tecnología Forestal, 2023-03)El cambio climático representa una amenaza creciente para la mayoría de los bosques alrededor del mundo (Anderegg et al. 2022). Eventos de decaimiento y de mortalidad de los bosques asociados con procesos fisiológicos de ... -
Integrating circadian and gibberellin signaling in Arabidopsis : Possible links between the circadian clock and the AtGID1 transcription
(Taylor & Francis, 2011-09)The circadian clock acts as central coordinator of plant activity, and it regulates key traits for plant fitness such as flowering time, gas exchange, growth and stress responses. In the May issue of the Proceedings of the ... -
Integrating genetics and suitability modelling to bolster climate change adaptation planning in Patagonian nothofagus forests
(2017)We investigated the impact of past changes in habitat suitability on the current patterns of genetic diversity of two southern beeches (Nothofagus nervosa and Nothofagus obliqua) in their eastern fragmented range in ... -
Invasive Insects in Forest Plantations of Argentina: Ecological Patterns and Implications for Management
(Springer Nature, 2020-02)Since the dawn of modern agriculture, humans have selected a few several species from the immense diversity nature has to offer, resulting in the same species being cultivated in very different countries and regions. Crops ... -
Low Intensity Breeding of Native Forest Trees in Argentina : Genetic Basis for their Domestication and Conservation
(Springer Nature, 2021)The first genetic studies on forest trees in Argentina were carried out with exotic fast-growing species and in relation to their productive use. These antecedents, conducted mainly by the National Institute of Agricultural ... -
Management of Nothofagus genetic resources: Definition of genetic zones based on a combination of nuclear and chloroplast marker data
(Elsevier, 2013-08-15)Development of appropriate forest conservation and management measures for a given tree species includes the identification of distinct genetically homogeneous units across its overall distribution range, which depends on ... -
Manejo de Bosques con Ganadería Integrada en Patagonia argentina: ajuste metodológico para la determinación de la línea de base en ecosistemas complejos y paisajes heterogéneos = Forest Management with Integrated Livestock in Argentine Patagonia: methodological adjustment for determining the baseline in complex ecosystems and heterogeneous landscapes
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2023-05)El Manejo del Bosque con Ganadería Integrada (MBGI) es una propuesta técnica que se basa en el manejo de los componentes forestal, ganadero, forrajero y ambiental, articulada como un plan predial factible de implementar. ... -
MBGI: Manejo del Bosque con Ganadería Integrada : ¿Cómo simplificar el monitoreo de campo?
(EEA Bariloche, INTA, 2022-06)El MBGI puede requerir el relevamiento de superficies grandes y heterogéneas en diferentes tipos de vegetación. La estrategia hoy aceptada para esta tarea esencial puede resultar muy complicada. Por este motivo, se propone ... -
Metodología de muestreo expeditivo ambiental/productivo para la determinación de líneas de base prediales en planes MBGI
(INTA - CIEFAP - CONICET, 2022)En el Manejo de Bosque con Ganadería Integrada (MBGI); las propuestas técnicas se basan en el manejo adaptativo de los componentes forestales; ganaderos; forrajeros; y ambientales que se deben plasmar en la presentación ... -
Mixed Nothofagus forest management: a crucial link between regeneration, site and microsite conditions
(Springer Nature, 2020)Canopy openings due to harvesting practices constitute a disturbance that changes the environmental conditions of microsites. Its impact on the relative performance of the regeneration of different tree species could also ... -
Molecular bases of responses to abiotic stress in trees
(Oxford University Press, 2020-06)Trees are constantly exposed to climate fluctuations, which vary with both time and geographic location. Environmental changes that are outside of the physiological favorable range usually negatively affect plant performance ... -
Native Forests Claim for Breeding in Argentina: General Concepts and Their State
(Springer, 2021)The first genetic studies on forest trees in Argentina were carried out with exotic fast-growing species and in relation to their productive use. These antecedents, conducted mainly by the National Institute of Agricultural ... -
Nothofagus pumilio and N. antarctica: The Most Widely Distributed and Cold-Tolerant Southern Beeches in Patagonia
(Springer, 2021)Nothofagus pumilio (Poepp. & Endl.) Krasser, known as lenga, and Nothofagus antarctica (G. Forster) Oerster, commonly called ñire, are tree species of the temperate forests of southern South America, occurring in temperate-rainy ... -
