Yield stability and phenotypic plasticity of Populus spp. clones growing in environmental gradients: I-yield stability under field conditions
(Elsevier, 2020-05)Populus species have been extensively cultivated in different regions around the world due to their growth performance, easy vegetative propagation and wood properties (for lumber, pulp, fiberboard and plywood). Stability ... -
Production ecology and reverse growth dominance in an old-growth ponderosa pine forest
(Elsevier, 2020-01)The growth of a stand is the sum of the growth of individual trees. Growth of individual trees can be explained by the amount of resources captured and how efficiently those resources are used (production ecology). The ... -
Ecuación de volumen total para Populus deltoides de plantaciones del Bajo Delta del Paraná
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-08)Las ecuaciones de volumen son una herramienta eficaz para la estimación del volumen del árbol individual, información que es esencial para la planificación y la gestión de rodales forestales. Las ecuaciones de volumen para ... -
Concentration and temporal variability of nitrogen, phosphorus and zinc in pecan leaves
(International Society for Horticultural Science, 2015)Information about the local response to fertilization in pecan trees is very limited. Here, we investigated the effects of fertilization with different levels of nitrogen (N), phosphorus (P) and zinc (Zn) on the chemical ... -
Wood structure, xylem functionality and growth of six Salix clones in two sites with different environmental stress in Argentina
(Sociedade de Investigações Florestais, 2018)The aims of the study were to evaluate the effects of abiotic stress (plantation site) and genotype (clone) on the wood anatomy and density of six Salix (willow) clones at three ages (2, 7, and 12 years), and the impact ... -
Ground Beetles in a Changing World: Communities in a Modified Wetland Landscape
(Springer, 2019-05)Wetlands are being increasingly affected by anthropogenic activities worldwide. The Lower Delta of the Paraná River, one of the most important wetlands in Argentina, has been profoundly altered because most of the natural ... -
Densidad y anatomia de la madera en familias mejoradas de sauces en Argentina = Densidade e anatomia da madeira em famílias melhoradas de salgueiros na Argentina
(Sociedade de Investigações Florestais, 2013-12)El objetivo del trabajo fue la evaluación de densidad y anatomía de la madera en siete familias de sauces, con vistas a seleccionar clones aptos para la producción de madera para usos sólidos y papel. Se cruzaron progenitores ... -
Populus deltoides ‘Australiano 129/60’: variación axial de la densidad y desarrollo de un modelo predictivo de la densidad del árbol completo = Populus deltoides clone 'Australian 129-60’: density axial variation and predictive model for whole tree density
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2010)Los objetivos de este trabajo fueron determinar la variación axial de la densidad de la madera de Populus deltoides ‘Australiano 129/60’ y desarrollar un modelo predictivo de la densidad total del árbol a partir de la ... -
Do greenhouse experiments predict willow responses to long term flooding events in the field? = ¿Experimentos en invernáculo predicen las respuestas de sauces a períodos largos de inundación a campo?
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2013-04)Flooding tolerance should be included as a trait in breeding programs in forested areas where extreme flooding events lasting several months can occur. In this context, it is difficult to carry out controlled, long-term ... -
The use of Leaf Surface Contact Cues During Oviposition Explains Field Preferences in the Willow Sawfly Nematus Oligospilus
(Nature Research, 2019-03-20)After an insect herbivore has reached its host plant, contact cues from the leaf surface often determine host acceptance. We studied contact cues during oviposition behavior of a willow pest, the sawfly Nematus oligospilus ... -
Communication interference in sympatrically occurring moth species
(Wiley, 2016-01)In moth species, females emit a species‐specific sex pheromone that is perceived over long distance by conspecific males. The species‐specificity in the chemical communication channel is achieved by a combination of unique ... -
Post-Fire Effects in Wetland Environments: Landscape Assessment of Plant Coverage and Soil Recovery in the Paraná River Delta Marshes, Argentina
(Springer, 2012-08)During 2008, under a region-wide drought, there were a large number of simultaneous fires in the Paraná River Delta region: the most affected vegetation was in marshes dominated by Schoenoplectus californicus (C.A.Mey.) ... -
Influence of growth dominance and individual tree growth efficiency on Pinus taeda stand growth. A contribution to the debate about why stands productivity declines
(Elsevier, 2012-08)A well recognized pattern during even-aged stands development is the growth decline after reaching a peak. We studied the effect of changes in stand structure, characterized by growth dominance, upon stand growth, stand ... -
Cambios en el crecimiento y la densidad de la madera en dos clones de álamo (Populus deltoides) debidos a la infección con roya (Melampsora medusae) = Growth and wood density changes in two poplar clones (Populus deltoides) due to rust (Melampsora medusae) infection
(Universidad Nacional de La Plata. Facultad de Ciencias Agrarias y Forestales, 2015)La roya, causada por distintas especies de Melampsora es una de las enfermedades más importantes de los álamos y puede reducir el crecimiento y la calidad de la madera. El objetivo de este trabajo fue evaluar la reducción ... -
