Variabilidad genotípica y ambiental del peso, tamaño y aceite del grano de girasol (Helianthus annuus L.) en el Noreste argentino
(Facultad de Ciencias Agrarias, Universidad Nacional del Nordeste, 2017)La relación tegumento/embrión es uno de los principales factores que afectan el porcentaje de aceite en girasol. Mayores proporciones de embrión incrementa la cantidad de aceite del grano. En la actualidad, no es claro el ... -
Variability for salt tolerance in a collection of Panicum coloratum var. makarikariense during early growth stages = Variabilidad en tolerancia a la salinidad en una colección de Panicum coloratum var. makarikariense durante las etapas tempranas de crecimiento
(CIAT, 2018-09)Our aim was to investigate variability for salt tolerance in a collection of Panicum coloratum var. makarikariense of INTA EEA Rafaela, Argentina. Panicum coloratum is a C4 perennial grass to be potentially used to increase ... -
Varroa destructor and Nosema sp seasonal dynamics in Apis mellifera colonies from temperate climate in Argentina = Dinámica estacional de Varroa destructor y Nosema sp en colonias de Apis mellifera en clima templado de Argentina
(Facultad de Ciencias Veterinarias, Universidad Nacional del Nordeste, 2022)Los ectoparásitos obligados Varroa destructor y Nosema sp afectan la salud de la abeja de la miel Apis mellifera y genera importantes pérdidas de la colonia. Este artículo describe y analiza información proveniente de ... -
Varroa destructor and viruses association in honey bee colonies under different climatic conditions
(2016-06)Honey bee colonies are threatened by multiple factors including complex interactions between environmental and diseases such as parasitic mites and viruses. We compared the presence of honeybee-pathogenic viruses and Varroa ... -
Vectorial competence of Amblyomma tonelliae to transmit Rickettsia rickettsii
(2016-12)The aim of this work was to test the vectorial competence of Amblyomma tonelliae (Ixodida: Ixodidae) to transmit Rickettsia rickettsii (Rickettsiales: Rickettsiaceae), the agent of Rocky Mountain spotted fever (RMSF). All ... -
Vigilancia de la resistencia antimicrobiana en animales: profundizar las iniciativas y ampliar las capacidades = Antimicrobial resistance surveillance in animals: to deepen initiatives and expand current capacities
(Elsevier, 2021-06)La resistencia antimicrobiana (RAM) comenzó a ser detectada poco después de que el uso de antimicrobianos (AM) se difundiera para el tratamiento de infecciones en seres humanos y animales. Sin embargo, durante los últimos ... -
Water table depth affects persistence and productivity of alfalfa in Central Argentina
(Elsevier, 2019-04)Alfalfa (Medicago sativa L.) is one of the most sown perennial legumes in the world. Water table depth can be both an opportunity and a threat for this crop. In this study we analyzed 20 years of field experimental data ... -
Which are important targets in development of S. aureus mastitis vaccine?
(2015-06)Staphylococcus aureus represents one of the leading causes of mastitis in dairy cows worldwide. S. aureus IMI have variable outcomes due to virulence of the strain involved, immune defenses of the host, and by antibiotic ... -
Worldwide host associations of the tick genus Ixodes suggest relationships based on environmental sharing rather than on co-phylogenetic events
(BioMed Central, 2023-02-21)This study aims to capture how ticks of the genus Ixodes gained their hosts using network constructs. We propose two alternative hypotheses, namely, an ecological background (ticks and hosts sharing environmentally available ... -
Yield components, light interception and radiation use efficiency of lucerne (Medicago sativa L.) in response to row spacing
(2013-02)Lucerne sowing is characterized by a rectangular spatial arrangement, i.e. greater distance between sowing rows than between plants in the row. Therefore, the reduction of row spacing generates more square spatial arrangements ... -
