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 ... -
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 ... -
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 ... -
Think globally, measure locally: The MIREN standardized protocol for monitoring plant species distributions along elevation gradients
(Wiley, 2022-02)Climate change and other global change drivers threaten plant diversity in mountains worldwide. A widely documented response to such environmental modifications is for plant species to change their elevational ranges. Range ... -
Tracking floristic archetypes of Patagonian steppes
(Wiley, 2024-03)Questions: The classification of plant communities is a well-established practice in ecology. However, the factors that determine the distribution of common species and the extent of their dominance and overlap are still ... -
Transcriptomic responses to drought stress in the Patagonian southern beech Nothofagus alpina
(Springer Open, 2024-05)Background: Deciphering the genetic architecture of drought tolerance could allow the candidate genes identification responding to water stress. In the Andean Patagonian forest, the genus Nothofagus represents an ecologically ... -
Unintended consequences of planting native and non-native trees in treeless ecosystems to mitigate climate change
(Wiley, 2024-03)Naturally treeless ecosystems are being replaced by native and non-native trees worldwide, often through deliberate afforestation using forestry tree species. By introducing species having novel traits, such as relatively ... -
Uso de “open top chambers” para simular escenarios de cambio climático en pastizales naturales de la Patagonia (sistema de mallines): Resultados preliminares.
(Asociación Argentina de Agrometeorología, 2016-09-20)Los experimentos de aumento artificial de temperatura son ampliamente aceptados y utilizados como metodologías para la investigación del cambio climático global (Shen y Harte 2000). Entre los métodos existentes (Niu et ... -
Variación y diferenciación genética de Nothofagus alpina: proyecciones para su domesticación y análisis de sus estrategias evolutivas en el contexto del cambio climático global
(Edición del Autor, 2018)En el contexto del cambio climático global, entender cómo reaccionarán los bosques y plantaciones forestales a los rápidos cambios climáticos futuros es uno de los mayores desafíos para los biólogos e ingenieros forestales. ... -
Vegetation responses to variations in climate: A combined ordinary differential equation and sequential Monte Carlo estimation approach
(Elsevier, 2023-03)Vegetation responses to variation in climate are a current research priority in the context of accelerated shifts generated by climate change. However, the interactions between environmental and biological factors still ... -
Vinculación de percepciones rurales con datos climáticos para el desarrollo de medidas de adaptación social y científicamente convalidadas
(Ediciones INTA, 2022)El cambio climático (CC) impacta en la agricultura familiar del mundo. Las medidas de adaptación (MDA) se aplican para hacer frente a este fenómeno. Aquí presentamos un caso donde MDA fueron desarrolladas a partir de ... -
What is hot in tree rings? The wood density of surviving Douglas-firs to the 2003 drought and heat wave
(Elsevier, 2008-08)In a global warming scenario, drought and heat waves like the one that occurred in 2003 in Europe are expected to become more intense and frequent. This extreme climate event strongly affected the hydraulic balance in many ... -
Worldwide diversity of endophytic fungi and insects associated with dormant tree twigs
(Springer, 2022-03)International trade in plants and climate change are two of the main factors causing damaging tree pests (i.e. fungi and insects) to spread into new areas. To mitigate these risks, a large-scale assessment of tree-associated ...
