Caracterización xilo-tecnológica de la madera de una plantación adulta de Pinus ponderosa de la patagonia argentina
Letourneau, Federico Jorge; Medina, Andrea Alejandra; Andia, Ismael R.; Andenmatten, Ernesto; De Agostini, N.; Mantilaro, Nicolás (Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-08)El conocimiento de las propiedades de la madera es esencial para su mejor utilización. Las maderas juvenil y madura difieren en su aptitud de uso, la primera puede emplearse como madera redonda o estructural limitada en ... -
Does competition management improve the ecophysiological response to water shortage of mixed woodland species of North Patagonia?
Varela, Santiago Agustin; Diez, Juan Pablo; Letourneau, Federico Jorge; Bianchi, Emilio; Weigandt, Mariana Noemi; Porté, A.J.; Sergent, Anne Sophie; Nacif, Marcos E.; Garibaldi, Lucas Alejandro; Fernandez, María Elena (Elsevier, 2023-08)Globally, the increasing forests vulnerability and drought-induced forest mortality events, extended to a larger scale, may have the potential to rapidly alter forest functioning and the provision of ecosystem services. ... -
Efecto de la aclimatación a la intensidad lumínica en vivero sobre el desempeño postrasplante de plantines de Austrocedrus chilensis
Letourneau, Federico Jorge; Namiot, Graciela Hebe; Perdomo, Marcelo H.; Basil, Juan Gustavo (Ediciones INTA, 2019-08)La restauración de bosques de Austrocedrus chilensis requiere plantines que soporten difíciles condiciones postrasplante. Durante la etapa de propagación en vivero, es común emplear cubiertas plásticas y mallas media sombra ... -
Looking at the forest from below: the role of seedling root traits in the adaptation to climate change of two Nothofagus species in Argentina
Duboscq Carra, Virginia Gisela; Letourneau, Federico Jorge; Pastorino, Mario Juan (2018-05)Global climate change (CC) is an evolutionary challenge for natural tree populations. Scientific experts forecast an increase in temperature and a decrease in precipitation in the Argentine Patagonian Cordillera. Knowledge ... -
Rentabilidad de la forestación con pino ponderosa (Pinus ponderosa (Dougl.) Laws) en el noroeste de la Patagonia, Argentina = Profitability of afforestation with ponderosa pine (Pinus ponderosa (Dougl.) Laws) in northwestern Patagonia, Argentina
Laclau, Pablo; Pozo, Luis M.; Huerta, Guillermo Jose; Andenmatten, Ernesto; Letourneau, Federico Jorge (Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2002)Conifer afforestation in the northwestern Patagonian provinces of Neuquén, Río Negro and Chubut has increased over the last few years, largely owing to federal and state government promotional policies. However, there is ... -
Where to find structural grade timber: a case study in ponderosa pine based on stand and tree level factors
Caballe, Gonzalo; Santaclara, Oscar; Diez, Juan Pablo; Letourneau, Federico Jorge; Merlo, Esther; Martinez Meier, Alejandro (Elsevier, 2020-03-01)Using portable acoustic tools, measurements of dynamic modulus of elasticity (Ed) were made in standing ponderosa pine (Pinus ponderosa (Dougl. ex Laws)) trees (n =437) growing in 22 stands encompassing the range of ... -
Why do Pinus species have different growth dominance patterns than Eucalyptus species? A hypothesis based on differential physiological plasticity
Fernandez, María Elena; Fernandez Tschieder, Ezequiel; Letourneau, Federico Jorge; Gyenge, Javier (Elsevier, 2011-03-15)It has been observed that Eucalyptus stands show high growth dominance levels while Pinus stands show null or low growth dominance levels. We hypothesized that this differential behaviour is linked to a higher degree of ...
