Genetic diversity and population structure in Nothofagus pumilio, a foundation species of Patagonian forests: defining priority conservation areas and management
(Springer Nature, 2020-11)Patagonian forests are the southernmost temperate forests in the world, and Nothofagus pumilio is one of their most ecologically important tree species (i.e., a foundation species). It presents great adaptability and a ... -
Heritable variation in the survival of seedlings from Patagonian cypress marginal xeric populations coping with drought and extreme cold
(Springer, 2012-01)The rear edges of tree species have begun to be perceived as highly valuable for genetic resources conservation and management. In view of expected climatic changes, the responses of trees at their xeric limits may largely ... -
Integrating circadian and gibberellin signaling in Arabidopsis : Possible links between the circadian clock and the AtGID1 transcription
(Taylor & Francis, 2011-09)The circadian clock acts as central coordinator of plant activity, and it regulates key traits for plant fitness such as flowering time, gas exchange, growth and stress responses. In the May issue of the Proceedings of the ... -
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 ... -
Management of Nothofagus genetic resources: Definition of genetic zones based on a combination of nuclear and chloroplast marker data
(Elsevier, 2013-08-15)Development of appropriate forest conservation and management measures for a given tree species includes the identification of distinct genetically homogeneous units across its overall distribution range, which depends on ... -
Manejo de Bosques con Ganadería Integrada en Patagonia argentina: ajuste metodológico para la determinación de la línea de base en ecosistemas complejos y paisajes heterogéneos = Forest Management with Integrated Livestock in Argentine Patagonia: methodological adjustment for determining the baseline in complex ecosystems and heterogeneous landscapes
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2023-05)El Manejo del Bosque con Ganadería Integrada (MBGI) es una propuesta técnica que se basa en el manejo de los componentes forestal, ganadero, forrajero y ambiental, articulada como un plan predial factible de implementar. ... -
Mixed Nothofagus forest management: a crucial link between regeneration, site and microsite conditions
(Springer Nature, 2020)Canopy openings due to harvesting practices constitute a disturbance that changes the environmental conditions of microsites. Its impact on the relative performance of the regeneration of different tree species could also ... -
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 ... -
Pattern of natural introgression in a Nothofagus hybrid zone from South American temperate forests
(Springer-Verlag Berlin Heidelberg, 2017-03-29)Interspecific gene flow is a common phenomenon in Nothofagaceae species; however, the dynamics of introgression in hybrid zones remains largely unknown. We focused on two ecologically and morphologically different Nothofagus ... -
Plantación de especies forestales nativas en matorrales de Patagonia norte: respuesta a la apertura inicial de dosel en sitios contrastantes = Planting native forest species in northern Patagonian woodlands: response to canopy opening in contrasting sites
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2023-05)Una estrategia de manejo forestal que podría combinar exitosamente la producción y la conservación de la biodiversidad en bosques naturales, es su enriquecimiento con árboles nativos de valor maderero. En ciertos bosques ... -
Red Argentina de Parcelas Permanentes de Bosques Nativos para promover colaboraciones científicas en estudios de largo plazo
(Asociación Argentina de Ecología, 2022-08)Las parcelas forestales permanentes son áreas de muestreo donde se registran periódicamente la identidad, abundancia y tamaño de los árboles, para estudiar cómo cambian los bosques en relación con el clima, los disturbios ... -
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 ... -
Shaping forces modelling genetic variation patterns in the naturally fragmented forests of a South-American Beech
(Elsevier, 2009-10)Fourteen natural populations of the South-American Beech Nothofagus obliqua at the Eastern naturally fragmented area of its distribution range were subjected to genetic analysis using genetic markers. The genetic ... -
Staying close: short local dispersal distances on a managed forest of two Patagonian Nothofagus species
(Oxford University Press, 2020-05)Understanding the impact of management on the dispersal potential of forest tree species is pivotal in the context of global change, given the implications of gene flow on species evolution. We aimed to determine the effect ... -
Structural–functional approach to identify post-disturbance recovery indicators in forests from northwestern Patagonia: a tool to prevent state transitions
(Elsevier, 2015-05)The disruption of the natural post-disturbance recovery process, either by changes in disturbance regime or by another disturbance, can trigger transitions to alternative degraded states. In a scenario of high disturbance ... -
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 Ambrosia Beetle Megaplatypus mutatus: A Threat to Global Broad-Leaved Forest Resources
(Entomological Society of America, 2022-08)We provide scientists and decision-makers with up-to-date information on Megaplatypus mutatus (Coleoptera: Curculionidae: Platypodinae), a forest insect native to South America that has invaded other regions. Emphasis is ... -
The effects of Quaternary glaciations in Patagonia as evidenced by chloroplast DNA phylogeography of Southern beech Nothofagus obliqua
