(Facultad de Ciencias Económicas, Universidad Nacional de Entre Ríos, 2021)El delta superior del río Paraná, es un área que viene experimentando profundas transformaciones desde inicios de la presente década. Desde hace más de diez años, el área está sujeta a diversas acciones que buscan su ... -
Optimizing resource productivity in soybean-based sequences through long-term crop intensification
(Elsevier, 2023-10)Context: Cropping systems based on a single crop per year, such as soybean monoculture, result in an inefficient use of available resources and low productivity, and are usually related with a negative environmental impact. ... -
Evaluation of sex pheromone formulations to attract Spodoptera frugiperda (Lepidoptera: Noctuidae) adult males in Argentina
(Sociedad Entomológica Argentina, 2019)Spodoptera frugiperda (Smith) is the most important pest of corn in Argentina. Its monitoring in the Americas is carried out by traps lured with a synthetic version of its female sex pheromone. Such monitoring has variable ... -
Régimen de precipitaciones en el centro oeste de Entre Ríos
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Entre Rios, 2019)En este trabajo se caracteriza el régimen pluviométrico de la zona centro oeste de Entre Ríos a distintas escalas de tiempo y se analiza y compara el comportamiento de las precipitaciones de 10 campañas agrícolas. A tal ... -
Occurrence patterns of the endangered Yellow Cardinal Gubernatrix cristata in north-east Argentina: only in savannahs and at sites away from roads
(BirdLife International, 2023)The endangered Yellow Cardinal Gubernatrix cristata is under pressure from habitat loss and from capturing for the cage bird trade. In north-east Argentina it is known to be associated with the Espinal ecoregion, but no ... -
Bird functional and taxonomic diversity in xerophytic forests: contributing to balance bird conservation and livestock production
(Elsevier, 2023-10)Biodiversity is increasingly dependent on the ecological state of agricultural and livestock systems. Here, we assess the relationship between bird functional and taxonomic diversity and forest structure along a gradient ... -
Identification of Molecular Markers and Candidate Genes Associated with Time to Flowering and Length of Reproductive Period in Soybean Through Association Mapping
(Springer, 2023-06)Adaptation to temporal stress can be achieved by modifying flowering time and lengthening the reproductive period. To identify genotypes, molecular markers, and genes related with these traits, a set of 94 soybeans were ... -
Reducción de emisiones de carbono por deforestación evitada en bosques del Espinal (Entre Ríos, Argentina) = Reduction of emissions by avoided deforestation in forests of Espinal (Entre Ríos, Argentina)
(Universidad Distrital Francisco José de Caldas, Colombia, 2021-12)Se estimó el carbono (C) almacenado en la biomasa aérea de bosques nativos del Espinal (Distrito del Ñandubay, provincia de Entre Ríos, Argentina) y la reducción de emisiones de CO2 por deforestación evitada. Se utilizó ... -
Modelos alométricos de biomassa aérea para Prosopis affinis Spreng. em florestas nativas Espinal da Argentina = Modelos alométricos de biomassa aérea para Prosopis affinis Spreng. em florestas nativas Espinal da Argentina
