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 ... -
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
(2018-05)Global climate change (CC) is an evolutionary challenge for natural tree populations. Scientific experts forecast an increase in temperature and a decrease in precipitation in the Argentine Patagonian Cordillera. Knowledge ... -
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 ... -
Monitoreo del crecimiento arbóreo en bosques nativos argentinos: una valiosa herramienta para estimar los impactos del cambio climático
(Red Argentina de Ciencia y Tecnología Forestal, 2023-03-27)El objetivo general de esta comunicación es dar a conocer la propuesta de implementación de un programa nacional de monitoreo del crecimiento de especies forestales nativas en diferentes ecosistemas de Argentina. Este ... -
Percepción del cambio climático en Patagonia Norte
(EEA Bariloche, INTA, 2021-08)Vincular las percepciones climáticas de los pequeños agricultores familiares con escenarios de cambio climático pasados y futuros puede utilizarse para desarrollar y aplicar medidas de adaptación social y científicamente ... -
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 ... -
