Plant‐based compounds with potential as push‐pull stimuli to manage behavior of leaf‐cutting ants
(2017-05)Leaf‐cutting ants are a serious pest of young forestry plantations. Currently, the main control method is the use of broad‐spectrum insecticides, which have a negative effect on non‐target organisms and the environment. ... -
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 ... -
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 ... -
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.) ... -
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 ... -
Proceso de planificación territorial inter-institucional y participativo del Bajo Delta del Río Paraná = Inter-institutional and Participatory Territorial Planning Process of the Lower Delta of the Paraná River
(Facultad de Ciencias, Universidad Central de Venezuela, 2022)En un sector de la Ecorregión Delta del Río Paraná (1.78 Millón de hectáreas, Argentina), un Proceso de Planificación Territorial inter-institucional y participativo se implementa como proyecto de intervención en un área ... -
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 ... -
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 ... -
Rendimiento y extracción de nutrientes en estaqueros de álamo del Delta del Paraná fertilizados con nitrógeno o fósforo
(2016)Los estaqueros de Salicáceas producen el material de propagación para las plantaciones clonales operacionales. Con la cosecha anual de guías del estaquero se exportan nutrientes del sistema y en consecuencia, en ciclos ... -
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 ... -
Responses of Trifolium repens L. root structure and function to shading and phosphorus shortage: limits to adaptative plasticity during establishment?
(Springer, 2023-07)Shading and low soil phosphorus availability may limit root growth of forage species in humid-temperate silvopastoral systems. However, plants are able to cope with such constraints by modifying root structure to improve ... -
Soil volume and carbon storage shifts in drained and afforested wetlands of the Paraná River Delta
(2013-03)Wetland ecosystems have a high carbon storage potential as a result of high primary productivity and low decomposition rates dictated by water saturation. In the herbaceous wetlands of the Paraná River Delta, drainage and ... -
The combination of crop diversification and no tillage enhances key soil quality parameters related to soil functioning without compromising crop yields in a low-input rainfed almond orchard under semiarid Mediterranean conditions
(Elsevier, 2023-04)Soils provide key ecosystem services and are crucial to combat climate change. Agriculture provides important ecosystem services but also causes negative environmental effects depending on agricultural management. In this ... -
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 ... -
