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 ... -
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 ... -
Conservation of the largest cervid of South America : interactions between people and the Vulnerable marsh deer Blastocerus dichotomus
(Cambridge University Press, 2017-07)Wild ungulates, and particularly deer, can cause severe damage to commercial plantations, resulting in reduced tolerance of their presence by forestry producers. The marsh deer Blastocerus dichotomus, categorized as ... -
Crop diversification effects on soil organic carbon and nitrogen storage and stabilization is mediated by soil management practices in semiarid woody crops
(Elsevier, 2023-09)Crop diversification is a promising strategy to mitigate climate change through soil carbon sequestration while ensuring soil fertility maintenance and food security. Here, we assess the impact of different inter-cropping ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Estrategias de conservación de la biodiversidad en paisajes forestales del bajo Delta del Paraná - Uniendo los actores clave de la región
(Sociedad Argentina para el Estudio de los Mamíferos (SAREM), 2017-07)Las consecuencias de las prácticas forestales sobre la biodiversidad varían según el manejo silvícola, del agua y el hábitat sustituido. Las plantaciones forestales pueden ser diseñadas y manejadas para preservar las ... -
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 ... -
Evaluación xilológica de familias mejoradas de sauces con destino industrial maderero = Xylem evaluation of improved willow families for timber industrial use
(Universidad Nacional de La Plata. Facultad de Ciencias Agrarias y Forestales, 2016)El objetivo del trabajo fue la evaluación a edad temprana de la anatomía y densidad de la madera y su relación con el crecimiento en diámetro, en familias de sauces producto de la etapa inicial de selección del programa ... -
Extreme flooding increases poaching mortality in the southernmost stronghold of the endangered marsh deer
(Sociedad Argentina para el Estudio de los Mamíferos (SAREM), 2023-01)Extreme stochastic perturbations can affect population dynamics, but quantitative assessments are scarce for threatened species. The 2015-2016 El Niño-Southern Oscillation (ENSO) caused extreme flooding in the Delta of the ... -
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 ... -
