Fijación de Carbono en ecosistemas boscosos y herbáceos del Norte de la Patagonia
(Universidad Nacional del Comahue, 2006)El cambio climático es uno de los problemas ambientales globales más preocupantes de la actualidad. El calentamiento atmosférico, producto del incremento en la concentración de gases causantes de efecto invernadero (GEI), ... -
Fin de año y de ciclo
(EEA Alto Valle, INTA, 2023-10)Editorial de Darío Fernández, director de la EEA Alto Valle. Analiza las temáticas abordadas en la edición Nº 95 de F&D, repasa cada uno de los temas y aprovecha la ocasión para hacer mención a su fin de mandato, siendo ... -
Genetic variation for tolerance to high temperatures in a population of Drosophila melanogaster
(John Wiley & Sons Ltd, 2018-10)The range of thermal tolerance is one of the main factors influencing the geographic distribution of species. Climate change projections predict increases in average and extreme temperatures over the coming decades; hence, ... -
Genomic responses to climate: Understanding local adaptation in the Andean tree species Nothofagus pumilio and implications for a changing world
(Wiley, 2024-03)Nothofagus pumilio is a foundation tree species that inhabits a 2000-km-long range in the southern Andes, a region with two perpendicular environmental gradients: temperature and photoperiod (North–South), and precipitation ... -
Grazing and ecosystem service delivery in global drylands
(American Association for the Advancement of Science, 2022-11-25)Grazing represents the most extensive use of land worldwide. Yet its impacts on ecosystem services remain uncertain because pervasive interactions between grazing pressure, climate, soil properties, and biodiversity may ... -
Growth response of Pinus contorta to the synergy of stress factors: successive extreme drought events and a population outbreak of Sirex noctilio in NW Patagonia
(Springer, 2022-02)The synergy of biotic and abiotic stress factors influences the response in growth, resistance, recovery and resilience of forest systems. This study used a dendrochronological approach to analyze the annual radial increase ... -
Huella ecológica de la producción frutícola convencional y orgánica en Río Negro y Neuquén
(EEA Alto Valle, INTA, 2022)Dentro de la fruticultura desarrollada en el Alto Valle de Río Negro y Neuquén existe la tendencia al incremento de la eficiencia de las prácticas convencionales para reducir el uso de insumos costosos, escasos o ambientalmente ... -
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 family farmers’ perceptions with meteorological records and national climate change projections to enhance site-specific adaptation knowledge
(Springer, 2023-12)Adaptation strategies to climate change (CC) that do not consider local perspectives tend to fail at specifc sites. Searching for complementary actions, we aimed to assess how farmers’ perceptions about climatic hazards ... -
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 ... -
Intensity and number of thinning operations affect the response of Eucalyptus grandis to water availability and extreme drought events
(Elsevier, 2023-02)Climate change has induced an increase in the frequency and intensity of droughts and heat waves, reducing growth and increasing the mortality risk of both natural and planted forests. Management practices are expected to ... -
Latitude, Elevation, and Mean Annual Temperature Predict Peat Organic Matter Chemistry at a Global Scale
(Wiley, 2022-02)Peatlands contain a significant fraction of global soil carbon, but how these reservoirs will respond to the changing climate is still relatively unknown. A global picture of the variations in peat organic matter chemistry ... -
Local adaptation along a sharp rainfall gradient occurs in a native Patagonian grass, Festuca pallescens, regardless of extensive gene flow
(Elsevier, 2020-03)Increasing global aridity combined with changing environmental conditions might cause irreparable alterations in arid and semiarid ecosystems. Knowledge of within-species genetic diversity and adaptive responses, especially ... -
Looking at the forest from below: the role of seedling root traits in the adaptation to climate change of two Nothofagus species in Argentina
