Clinal variation along precipitation gradients in Patagonian temperate forests: unravelling demographic and selection signatures in three Nothofagus spp.
(Springer Nature, 2020-01-10)Past demographic changes and current selection pressures determine the genetic variation displayed by Nothofagus species along rainfall gradients. Based on the diversity trends observed at candidate genes associated to ... -
Different drought‑adaptive capacity of a native Patagonian tree species (Nothofagus pumilio) resulting from local adaptation
(Springer, 2021-06)The resistance of different genotypes to abiotic stress may be due to genetic effects and/or to phenotypic plasticity allowing them to acclimate to variable conditions. The contribution of one or the other mechanism ... -
Do populations of Festuca pallescens from a rainfall gradient differ in the expression of morpho-physiological traits under drought stress?
(Elsevier, 2023-06)In arid environments, stochastic rainfall and high evapotranspiration force plants to optimize water resources. North Patagonia is characterized by a deep rainfall gradient that gives rise to environments with very contrasting ... -
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 ... -
Physiological status of conifer seedlings treated with radiation, drought and frost stress mitigation techniques: a laboratory assessment
(2016)En la región oriental del noroeste de la Patagonia, se levanta del rápido crecimiento de coníferas exóticas Pinus ponderosa (pino ponderosa) y Pseudotsuga menziesii (Abeto de Douglas) se están estableciendo en lugares que ... -
Seedling drought stress susceptibility in two deciduous Nothofagus species of NW Patagonia
(2010-06)The physiological capacities of seedlings to cope with drought may be subject to strong selective pressure in the context of future climate scenarios, threatening the regeneration and sustainability of forests. Characterization ... -
Sex-related difference in susceptibility to cypress mortality in Austrocedrus chilensis from Northwestern Patagonia (Argentina) = Susceptibilidad diferencial al mal del ciprés entre sexos de Austrocedrus chilensis en la Patagonia (Argentina)
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2012)Female and male individuals of dioecious species have different reproductive functions and sex-related differences have been reported in growth rate, age at maturity, size, spatial distribution and physiological responses ... -
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 ...
