Early rooting and flooding tolerance in cuttings from a Populus deltoides full-sib family under greenhouse conditions
(Canadian Science Publishing, 2020-10-26)Populus deltoides is an important forest tree, with elite genotypes propagated mainly as unrooted dormant cuttings. Several areas where P. deltoides is planted periodically experience flooding episodes. The aims of this ... -
Poplar leaf rust reduces dry mass accumulation and internal nitrogen recycling more markedly under low soil nitrogen availability, and decreases growth in the following spring
(Oxford University Press, 2019-01)Rust is one of the most important biotic stress factors that affect poplars. The aims of this work were: (i) to analyze the changes in growth and nitrogen (N) accumulation in Populus deltoides W. Bartram ex Marshall plants ... -
¿La combinación de clones posee alguna ventaja sobre los sistemas monoclonales? : posibles alternativas silviculturales para las Salicáceas, a partir de la revisión de experiencias previas
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2020-12)Las plantaciones forestales han sido tradicionalmente desarrolladas a partir de material de propagación de origen seminal. Sin embargo, las principales especies plantadas en el mundo se pueden propagar vegetativamente, por ... -
Push‐pull to manage leaf‐cutting ants: an effective strategy in forestry plantations
(Wiley, 2020-08)BACKGROUND: Leaf‐cutting ants (LCAs) are amongst the most important forestry pests in South America. Currently, their control is carried out almost exclusively through the application of toxic baits of restricted use. Here ... -
Evaluación preliminar del estado de conservación de plantas: comparación de dos métodos aplicados al género Gavilea (Orchidaceae) = Preliminary evaluation of the conservation status of plants: comparison of two methods app lied to the genus Gavilea (Orchidaceae)
(Sociedad Argentina de Botánica, 2019-09)Introducción y objetivos: Conocer el estado de conservación de las especies es fundamental para dar prioridad de intervención y manejo a las poblaciones de las especies más amenazadas. Muchas veces la información disponible ... -
El proceso de fermentación en la producción artesanal de hidromiel y su evaluación sensorial
(Facultad de Agronomía, Universidad de Buenos Aires, 2020)En el hidromiel confluyen las ideas de alimentación natural y saludable relacionadas con la miel, con las de un producto artesanal y gourmet. La oferta de este producto se está expandiendo en las ferias regionales de todo ... -
Determinants of capybara presence in afforestations of the lower delta of the Paraná river, Argentina
(Taylor & Francis, 2015)The delta of the Paraná River in Argentina represents the southernmost stronghold for capybaras (Hydrochoerus hydrochaeris), but this area is highly modified due to commercial afforestations with Salicaceae. Water management ... -
A small protected area facilitates persistence of a large carnivore in a ranching landscape
(Elsevier, 2020-05)Assessments of the role that small (<500 km2) protected areas play in conservation of large carnivores in landscapes where the species are persecuted are scarce. Using camera-trap sampling we estimated puma (Puma concolor) ... -
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 ... -

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.
