Climate-influenced performance and offspring development of merino sheep in a dry temperate-cold valley
(Elsevier, 2024-04)This study aims to explore the effects of climate on the performance and offspring development of aged Merino sheep relocated from an arid, cold environment with harsh grazing conditions to a dry, temperate-cold valley ... -
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, ... -
Host plant choice and effect of temperature on feeding behaviour of Perzelia arda (Lepidoptera: Depressariidae), a leaf-tying larva, on Nothofagaceae from the Andean Patagonian forest
(Wiley, 2021-08)Environmental temperature may cause changes in the physiology and feeding behaviour of herbivorous insects and, consequently, in the damage they can cause. In the Andean Patagonian forest, an eco-region dominated by trees ... -
New precipitation and temperature grids for northern Patagonia: Advances in relation to global climate grids
(Chinese Meteorological Society, 2016-02)Climate data of mean monthly temperature and total monthly precipitation compiled from different sources in northern Patagonia were interpolated to 20-km resolution grids over the period 1997–2010. This northern Patagonian ... -
Physiological and morphological short-term responses to light and temperature in two Nothofagus species of Patagonia, South America
(2012-12)The study of plant responses to environmental stress factors is essential for management of plant systems and for anticipating their response to climate change. The main goal of this study was to determine morphological ... -
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 ... -
Seed dormancy responses to temperature relate to Nothofagus species distribution and determine temporal patterns of germination across altitudes in Patagonia
(2015-08-26)Seeds integrate environmental cues that modulate their dormancy and germination. Although many mechanisms have been identified in laboratory experiments, their contribution to germination dynamics in existing communities ... -
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 explains variable spread rates of the invasive woodwasp Sirex noctilio in the Southern Hemisphere
(2014-02)La frecuencia de introducciones de no indígena insectos forestales en nuevos hábitats va en aumento en todo el mundo, a menudo con consecuencias profundamente negativas sobre los ecosistemas naturales y las plantaciones ... -
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 ...
