Population genetic structure and historical dispersal patterns in the subterranean rodent Ctenomys “chasiquensis” from the southeastern Pampas region, Argentina
(Elsevier, 2016-05)Gene flow plays an essential role in the evolutionary history of the organisms and helps to identify those historical landscape features that most likely had affected the dispersal patterns. In this work, we assess, using ... -
Predicting the distribution of plant species from southern South America: are the hotspots of genetic diversity threatened by climate change?
(Springer, 2024-01)Biodiversity in all its dimensions is being threatened by climate change and the impact of human activities. Genetic diversity is a key dimension of biodiversity underlying adaptation to global changes. Here we assess the ... -
Questions, Perspectives and Final Considerations of Planting Native Species Under the Climate Change Conditioning
(Springer, 2021)There is a growing interest in Argentina (and in the world) for planting native tree species. This has triggered the development of domestication programs for those species with greater productive potential or a key ... -
¿Qué calidad de madera produciremos en el futuro?, un análisis sobre los desafíos de integrar valor adaptativo y tecnológico ante un clima cambiante
(EEA Bariloche, INTA, 2019-09)La madera cumple funciones de transporte y almacenamiento de agua, nutrientes y carbohidratos, fundamentales para la sobrevivencia de las especies leñosas frente a variaciones del ambiente. La densidad de la madera, una ... -

Reponse du Douglas a des evenements climatiques extremes
(Edición del Autor, 2009-01-13)La température de la terre a augmenté de 0,7 °C au cours du siècle dernier, ce qui correspond à une vitesse de réchauffement jamais observée auparavant. Les prévisions et la particularité du changement climatique global, ... -
Resiliencia y resistencia forestal en tiempos de cambio climático
(Ediciones INTA, 2019-12)Los bosques se encuentran expuestos en la actualidad a condiciones climáticas extremas. Esto vuelve incierta su supervivencia y resalta la importancia de tomar medidas hoy para garantizarla. Aunque no sabemos con exactitud ... -
Respuestas a la temperatura en especies del género Nothofagus distribuidas en un gradiente altitudinal
(Edición del Autor, 2019-03-07)Las predicciones del Cambio Clim´atico Global para el noroeste de la Patagonia indican un aumento de la temperatura media, acompañado de mayor frecuencia de eventos extremos. En este contexto, es fundamental comprender la ... -
Respuestas morfológico-fisiológicas ante distintos tipos e intensidades de estrés en dos especies patagónicas del genéro Nothofagus con aptitud comercial
(Facultad de Agronomía, Universidad de Buenos Aires, 2010-09)Algunas especies nativas andino - patagónica poseen alto valor maderero. La utilización de las mismas en cultivo requiere del conocimiento de su respuesta fisiológica y morfológica frente a factores ambientales generadores ... -
Resumen de una temporada muy especial
(EEA Alto Valle, INTA, 2023)La edición Nº93 de la revista F&D realiza un repaso por las principales particularidades de una temporada que tuvo características muy especiales en el aspecto climático. Esta situación generó diversos efectos sobre la ... -
Ring density record of phenotypic plasticity and adaptation to drought in Douglas-fir
(Elsevier, 2009-08)Microdensity profiles of Douglas-fir’s clones and weather data were used to study phenotypic plasticity (dendroplasticity). Within-ring microdensity was interpreted as the variation of tree response to drought constraints ... -
“El rol del extensionista tiene que ver con la comunicación, la rigurosidad técnica y la organización de los productores”
(EEA Alto Valle, INTA, 2023-10)Rafael De Rossi, ingeniero agrónomo con 30 años de experiencia en la Agencia de Extensión Rural INTA Río Colorado, brindó una extensa entrevista a pocos meses de haberse jubilado, en la que repasa anécdotas y brinda ... -
Should tree invasions be used in treeless ecosystems to mitigate climate change?
(The Ecological Society of America, 2021)Intentionally allowing or promoting invasion by non-native trees into areas characterized by treeless vegetation could contribute to climate-change mitigation by increasing carbon (C) sequestration. In some areas of the ... -
Stand density and drought interaction on water relations of Nothofagus antarctica : contribution of forest management to climate change adaptability
(2011-12)Nothofagus antarctica is the most representative species of the native mixed forest occupying ecotone areas between forests and steppe in NW Patagonia, South-America. In this type of environment, vulnerability to climate ... -
Strains in Sustainability Debates: Traditional Ecological Knowledge and Western Science through the Lens of Extension Agents in a Pastoral Region
(Wiley Online Library, 2020-03)Those involved in sustainability debates on developmental pathways concur in the synergistic potential of integrating traditional ecological knowledge (TEK) and Western scientific approaches. Transhumant pastoralism is a ... -
Surface indicators are correlated with soil multifunctionality in global drylands
(Wiley, 2020-02)1. Multiple ecosystem functions need to be considered simultaneously to manage and protect the several ecosystem services that are essential to people and their environments. Despite this, cost effective, tangible, relatively ... -
Temperature and day length drive local adaptation in the Patagonian foundation tree species Nothofagus pumilio
(BioRxiv, 2023-04-29)Climate change alters relationships among environmental conditions and thus has the potential to change the selection pressures acting on adaptive gene variants. Using a landscape genomic approach, we show that the southern ... -
Temperature and host plant species affect the performance and immunocompetence of an outbreak defoliator in northwestern Patagonia
(Royal Entomological Society, 2022-03)1. Rising temperature has been associated with increased occurrence of herbivorous insect outbreaks, explained by several direct and indirect mechanisms. Whereas natural enemies are known key drivers of forest-defoliating ... -
The impact of different natural environments on the regeneration dynamics of two Nothofagus species across elevation in the southern Andes
(Elsevier, 2020-05-15)A widely accepted paradigm in forest ecology proposes that patterns of relative abundance among mature forest trees are largely influenced by biotic and abiotic processes that operate most intensely during the earliest ... -
