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 ... -
Tolerancia a la inundación en sauces plantados en la Argentina: conocimiento actual y perspectivas = Flooding tolerance in willows planted in Argentina: current knowledge and perspectives
(Universidad Nacional de La Plata. Facultad de Ciencias Agrarias y Forestales, 2018)En el Delta del Paraná se encuentra el núcleo principal de plantación de sauces en la Argentina. Una consecuencia prevista por los escenarios de cambio climático es un incremento de la frecuencia de inundaciones para la ... -
Heptyl butyrate, a putative pheromone involved in social communication of Vespula germanica wasps
(2018-02)Greater knowledge on the social communication of invasive Vespula germanica wasps is needed to fully understand their foraging behavior. This is particularly valuable considering that poison baiting is currently the only ... -
Linking competition with Growth Dominance and production ecology
(2018-04-15)The development of forests over time is influenced by competition for resources among trees, leading to patterns of size hierarchy. These two aspects – competition and size hierarchy – can be examined in conjunction with ... -
Acclimation of cuttings from different willow genotypes to flooding depth level
(2018-05)Climate change will increase the frequency of extreme rain events, causing more flooding episodes. Willows are usually planted in marginal lands like flood prone areas. For willow plantations developed from rootless cuttings, ... -
Resilience of willows (Salix spp.) differs between families during and after flooding according to floodwater depth
(2018-08-14)Although the morphological and physiological responses of willows to flooding have already been characterized, less is known about their responses during the post-flooding period. After the end of the stress episode, plants ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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) ... -
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 ... -
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 ... -
¿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 ... -
