Sensibilidad de indicadores biológicos edáficos en un Argiudol de la Región Pampeana Argentina
(Sociedad Española de la Ciencia del Suelo, 2015)Mantener la calidad de los suelos y la productividad de los cultivos es un desafío importante para la agricultura moderna. Prácticas de manejo que tiendan a incrementar el contenido de carbono del suelo y a la vez favorecer ... -
Servicios de los ecosistemas: un recorrido por los beneficios de la naturaleza
(Facultad de Agronomía, Universidad de Buenos Aires, 2012)Numerosos trabajos han sido desarrollados abordando el tema servicios de los ecosistemas. En esta ocasión, se presenta una revisión acerca del alcance de estos trabajos a nivel mundial. Para ello, se revisa la evolución ... -
Soil lead pollution modifies the structure of arbuscular mycorrhizal fungal communities
(Springer, 2019-04-23)The impact of lead (Pb) pollution on native communities of arbuscular mycorrhizal fungi (AMF) was assessed in soil samples from the surroundings of an abandoned Pb smelting factory. To consider the influence of host identity, ... -
Soybean yield and water productivity gaps associate with ENSO-dependent effects of fungicide, sowing date and maturity group
(Elsevier, 2024-04)Context: Soybean, the focus of this study, is the most widely sown crop and the main source of external income in Argentina. The reported soybean yield gap calculated as the difference between water-limited potential yield ... -
Spatial and temporal plant-to-plant variability effects on soybean yield
(2018-08)Plant density and row spacing are management practices that farmers use to maximize soybean (Glycine max (L.) Merr.) yield. Other canopy aspects related to seedling establishment like spatial (spacing among plants) and ... -
Spontaneous fractures and hypocuprosis in pen-backgrounded Holstein calves
(Brazilian Association of Veterinary Pathology, 2023-11-02)Bone fractures are a frequent cause of limp in cattle, being pre-existing bone lesions among the predisposing factors. However, there is scant information about the natural occurrence of bone disease. This report aimed to ... -
SSR markers linked to stem canker resistance in soybean Glycine max
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020)In this work, we studied 40 samples of Diaporthe phaseolorum var. meridionalis (Dpm), causal agent of stem canker in soybeans (SCS). In the susceptible genotype Golondrina65 the isolate RSF12 showed the highest percentage ... -
Streptococcus suis serotype 2 strains isolated in Argentina (South America) are different from those recovered in North America and present a higher risk for humans
(2016-10)Introduction: Streptococcus suis serotype 2 is an important swine pathogen and emerging zoonotic agent causing meningitis and septicemia/septic shock. Strains are usually virulent (Eurasia) or of intermediate/low virulence ... -
Target-site and non-target-site resistance mechanisms confer multiple resistance to glyphosate and 2,4-D in Carduus acanthoides
(Elsevier, 2023-04)Carduus acanthoides L. is mainly a range-land weed, but in the 2010s has begun to invade GM crop production systems in Córdoba (Argentina), where glyphosate and 2,4-D have been commonly applied. In 2020, C. acanthoides was ... -
Unveiling the occurrence of Melanaphis sorghi in Argentina following a major aphid outbreak
(Springer, 2022-09-14)Severe aphid outbreaks were recorded on sorghum (Sorghum bicolor (L.) Moench) and Johnson grass (Sorghum halepense (L.) Pers.) during the 2020/2021 and 2021/2022 cropping seasons in Argentina. The general aspect of the ... -
Valoración económica de la polinización entomófila en cultivos de la Argentina: posibles efectos de la crisis de polinizadores en la agricultura
(Sociedad Entomológica Argentina, 2023-04)En la República Argentina la producción de alimentos es la base del desarrollo económico y social. Varios cultivos dependen de la polinización entomófila, por lo que este servicio ecosistémico es relevante. Sin embargo, ... -
Wheat grains damaged by Fusarium graminearum: alterations in yield, toxicity and protein composition
(Springer, 2019-08-26)The aim of this study was to investigate alterations on wheat grains, in relation to yield and quality parameters, such as infection degree, protein composition and toxicity caused by isolates of Fusarium graminearum with ... -
Wild pigs (Sus scrofa) population as reservoirs for deleterious mutations in the RYR1 gene associated with Porcine Stress Syndrome
(Elsevier, 2020-12)Porcine Stress Syndrome (PSS) is a disorder codified by the ryanodine receptor 1 gene (RYR1) and affects both animal welfare and the quality of the meat product. As a consequence, individuals with this syndrome generate ...
