(Sociedad Argentina de Botánica, 2011-06)Conocer la distribución natural de cualquier especie es esencial para poder planificar su conservación o uso. El Raulí [Nothofagus alpina (Poepp. & Endl.) Oerst. = Nothofagus nervosa (Phil.) Dim. et Mil.] y el Roble Pellín ... -
Ectomycorrhizal fungal communities in Nothofagus nervosa [Rauli] : a comparison between domesticated and naturally established specimens in a native forest of Patagonia, Argentina

Ectomycorrhizas naturally established in Nothofagus nervosa seedlings under different cultivation practices in a forest nursery
(Springer, 2013-10)Mycorrhizas are mutualistic associations between soil fungi and plant roots which usually improve water and nutrient uptake, influencing plant fitness. Nothofagus nervosa (Raulí) is an ecologically and economically important ... -

(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2015)Las prácticas silviculturales constituyen un importante agente de disturbio y su inadecuada implementación afecta la sostenibilidad de los bosques naturales. En la Reserva Nacional Lanín, el manejo silvicultural del bosque ... -
Efecto del manejo silvícola en la dinámica de la regeneración de Nothofagus alpina, N. obliqua y N. dombeyi bajo diferentes condiciones ambientales
(Red Argentina de Ciencia y Tecnología Forestal, 2023-03)La regeneración de los bosques es la base de la renovación y la continuidad de las especies, lo que la convierte en uno de los procesos más importantes en el ciclo de vida de los árboles (Norden 2014). En la dinámica ... -
The effect of silvicultural management on the genetic diversity of a mixed Nothofagus forest in Lanín Natural Reserve, Argentina
(2016-03)El conocimiento del impacto de las prácticas de manejo forestal es crucial para permitir el uso de los recursos naturales garantizando al mismo tiempo la sostenibilidad de la variación genética, que es esencial para la ... -
Effects of climate on the radial growth of mixed stands of Nothofagus nervosa and Nothofagus obliqua along a precipitation gradient in Patagonia, Argentina
(Elsevier, 2022-08)Climate models for North Patagonia in Argentina project dryer conditions, due to a decrease in mean precipitation combined with an increase in mean temperatures. The temperate mixed Nothofagus forest, which exists along a ... -
Ensamblado del transcriptoma de novo y análisis de expresión diferencial de genes en respuesta al estrés hídrico en Nothofagus alpina
(Red Argentina de Ciencia y Tecnología Forestal, 2023-03)Los bosques cumplen un rol de importancia en la regulación de las temperaturas y el ciclo del agua a través de la evapotranspiración (ET) el cual está siendo afectado por escenarios de recurrentes sequías (Diao et al. ... -
Environmental gradients as “natural labs” for elucidating the regeneration dynamics of three Nothofagus species under different climatic scenarios in Patagonia
(2018-09)We work in Patagonian forests, the southernmost woody ecosystems of the world, in which three tree species have a clear altitudinal distribution. Nothofagus obliqua is frequent at 650-850 m above the sea level, N. nervosa ... -
Evaluación al quinto año del primer ensayo en campo de orígenes argentinos de lenga (Nothofagus pumilio (Poepp. & Endl.) Krasser)
(GeMFO, 2022-09)En 2017 se instaló un ensayo de 10 orígenes argentinos de lenga en Bariloche, con 3 repeticiones de 9 plantas (N= 270) en DBCA. En 2022 se midió la altura y el diámetro al cuello de cada planta, y se registró la mortalidad. ... -
Evidence of genetic determination in the growth habit of Nothofagus pumilio (Poepp. & Endl.) Krasser at the extremes of an elevation gradient
(Taylor & Francis, 2020)In temperate mountainous regions, altitudinal clines in tree size and growth habit develop from a gradual adjustment of multiple traits to tolerate harshening conditions with altitude. We perform a common garden trial with ... -
Factors affecting success of galls of Aditrochus coihuensis (Hymenoptera: Pteromalidae) = Factores que afectan el éxito de las agallas de Aditrochus coihuensis (Hymenoptera: Pteromalidae)
(Sociedad Entomológica Argentina, 2011-12)Galls of Aditrochus coihuensis (Hymenoptera: Pteromalidae) were collected from their host tree, the southern beech Nothofagus dombeyi, near San Carlos de Bariloche, Argentina, during the spring of 2007. Galls were carefully ... -
