First records of pigmentation anomalies in the marsh deer at its southernmost stronghold: a warning message?
(Springer, 2023-05)Pigmentation anomalies (e.g., albinism, leucism) in Neotropical mammals are considered rare. Identifying the spatiotemporal distribution and prevalence of pigmentation anomalies is important to better assess the evolutionary ... -
Ground beetles (Coleoptera: Carabidae) inhabiting anthropogenic habitats in the lower delta of the Paraná river, Argentina: geographic distribution and ecological characteristics
(2017)The primary aims of this paper were to provide the first inventory of carabid beetles collected in five different anthropogenic habitat types of the Lower Delta of the Paraná River, to describe their main ecological ... -
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 ... -
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 ... -
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 ... -
Interacciones entre sitio, plaga y una enfermedad del fuste en una plantación de Populus deltoides cv. Catfish-2 en el bajo delta del Río Paraná (Argentina)
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (España), 2002)El objetivo del trabajo fue estudiar la relación entre la calidad de sitio de plantación de álamos con los daños causados por el «Taladro de los Forestales» (Platypus mutatus Chapuis) y la relación con una enfermedad del ... -
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 ... -
Nuevas especies de mamíferos para el Bajo Delta del Paraná y bajíos ribereños adyacentes, Buenos Aires, Argentina
(Sociedad Argentina para el Estudio de los Mamíferos (SAREM), 2010-12)Se reportan los primeros registros de presencia para cuatro especies de mamíferos (Dasypus novemcinctus, Cerdocyon thous, Procyon cancrivorus y Axis axis) en el sector bonaerense del Bajo Delta del río Paraná y bajíos ... -
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
