Behavioral responses of Imidacloprid-Dosed farmland birds to a simulated predation risk
(ACS Publications, 2024-07)Sublethal exposure to imidacloprid and other neonicotinoid insecticides may affect the neurological functions of birds. As such, behavior may be compromised. Here, we tested experimentally the effects of 1 and 6 mg/kg bw ... -
Biomass Carbon and Nitrogen allocation in different tree species: do tree compartments and size affect C:N relationship?
(Finnish Society of Forest Science, 2022)Tree carbon (C) and nitrogen (N) concentrations and C:N ratio are critical for understanding the elemental compositions of forests, N use efficiency, productivity and the biogeochemical cycles. We evaluate differences in ... -
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 ... -
Caracterización de la cuenca del Arroyo Estacas y relación con el uso del suelo y la morfología del cauce
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Entre Ríos, 2019)La caracterización morfométrica de una cuenca es una etapa inicial de la modelación de la dinámica hídrica y procesos erosivos asociados. Los objetivos del trabajo fueron caracterizar la cuenca del Arroyo Estacas y su cauce ... -
Characterization of multispectral aerial images of sugarcane
(IOP Science, 2013)In this paper we present a implementation and characterization the status of sugarcane plantations based on the analysis of multispectral aerial images. Currently there are no precise techniques to estimate objectively the ... -
Comportamiento de variedades de lino oleaginoso en el sudeste de Buenos Aires, Argentina
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2023-09)El cultivo de lino oleaginoso (Linum usitatissimum L.) se realiza en algunos establecimientos del Sudeste Bonaerense y presenta oportunidades de negocio a pesar de no contar con un importante caudal de información actualizada. ... -
Conservation of ecosystem services in Argiudolls of Argentina
(MDPI, 2020-12-19)Mollisols are a fundamental component of global agricultural production. In the Argentine Pampas region, 65% of the Mollisols belong to Argiudoll great group. These soils have an agricultural aptitude, with limitations ... -
Contemporary challenges and opportunities for the management of bird damage at field crop establishment
(Elsevier, 2021-06)Bird damage, from sowing to crop establishment, is an important issue for farmers in many parts of the world. However, reliable and cost-effective solutions remain elusive because management tools and research on the subject ... -
Contribución al estudio de la ecología y biología de Epicauta atomaria (Coleoptera: Meloidae), insecto asociado a cultivos agrícolas en América del Sur
(Ediciones INTA, 2021-12)Epicauta atomaria (Meloinae: Epicautini) es un meloideo que pertenece al grupo de especies Epicauta maculata. Es nativo de América del Sur con un rango de distribución muy amplio que va desde los 15° N, en el centro de ... -
Contribution of honeybees to soybean yield
(Springer, 2018-02)Despite the economic importance of soybean [Glycine max (L.) Merr.], knowledge on the contribution of entomological pollination on seed yield is scarce. This study estimates the production of soybean resulting from pollination ... -
A contribution to understanding the origin of platy structure in silty soils under no tillage
(2016)In silty soils under no tillage (NT), platy (P) soil structure is widespread and constrains water infiltration. Our objectives were (i) to evaluate how traffic and the presence of crop residues influence P structure ... -
Conyza bonariensis as an alternative host for Colletotrichum species in Argentina
(Wiley, 2020-10)Aims: This study investigated the diversity of Colletotrichum isolates recovered from Conyza bonariensis leaves through the use of morphological characteristics, growth rate, carbon sources utilization and phylogenetic ... -
Cover crop benefit bacteria and increase aggregate-associate soil C and N storage
(Elsevier, 2024-03)The aim of this study was to analyze the effect of four crop sequences with different aboveground biomass and crop residue biochemical composition on biological soil variables, fractions of soil organic matter, and soil ... -
Critical bulk density for a Mollisol and a Vertisol using least limiting water range: effect on early wheat growth
(2013-01)The least limiting water range (LLWR) integrates crop growth-limiting values based on easily measurable parameters such as soil water content and bulk density (BD) and has been validated as a valuable soil physical quality ... -
Crop nitrogen status of early- and late-sown maize at different plant densities
(Elsevier, 2020)In maize (Zea mays L.) crops, nitrogen (N) status at silking (R1) has been used to predict grain yield (GY) response to N fertilization and to develop strategies to manage crop nutrition in order to match N supply with ... -
Crop sequence and P fertilization effects on soil P fractions under no-tillage
(Springer, 2021-05-27)Increasing cropping intensity may affect phosphorus (P) recycling through crop residue inputs, which may differ in soils with different productivity, P adsorption capacity, and P fertilization level. In three crop sequences: ... -
Current status of soybean anthracnose associated with Colletotrichum truncatum in Brazil and Argentina
