Proteomic, metabalomic, and biochemical analysis of heat treated Valencia oranges during storage
(Elsevier, 2011-11)Heat treatment induces defense mechanisms and triggers physiological responses that allow citrus fruit to withstand stressful conditions during storage. The aim of this paper was to identify changes in the proteome and the ... -
Life history traits of the coccinellids Scymnus subvillosus and S. interruptus on their prey Aphis spiraecola and A. gossypii: Implications for biological control of aphids in clementine citrus
(Elsevier, 2019-05)Predator-prey interactions are not static, but spatially and temporally dynamic. In addition to the climatic conditions and the prey density, the dynamics of predator populations may be influenced by the suitability of ... -
Endophytes of native grasses from South America: biodiversity and ecology
(Elsevier, 2012-06)We review and present preliminary results of studies on cool-season grass endophytes native to South America. These fungi have been studied only in Argentina, where they have been detected in 36 native grass species. The ... -
Validation of models to estimate the fumigant and larvicidal activity of Eucalyptus essential oils against Aedes aegypti (Diptera: Culicidae)
(Springer, 2012-05)The aim of this work is to validate the pre-existing models that relate the larvicidal and adulticidal activities of the Eucalyptus essential oils on Aedes aegypti. Previous works at our laboratory described that the ... -
Efecto del fuego o el corte sobre la producción y la calidad forrajera de un pajonal dominado por Panicum prionitis = Effect of fire or mowing on the forage supply and quality of a Panicum prionitis tall grassland
(Asociación Argentina de Producción Animal, 2017-06)El aumento de superficie destinada a la agricultura ha provocado el desplazamiento de la ganadería hacia ambientes tradicionalmente clasificados como “marginales”. Este es el caso de islas y campos bajos del valle de ... -
Proteomic and metabolomic approaches unveil relevant biochemical changes in carbohydrate and cell wall metabolisms of two blueberry (Vaccinium corymbosum) varieties with different quality attributes
(Elsevier, 2018-12)Quality maintenance in rapidly decaying fruit such as blueberries (Vaccinium corymbosum) is of essential importance to guarantee the economic success of the crop. Fruit quality is a multifaceted subject that encompasses ... -
Resiliencia de un pajonal de Panicum prionitis Nees bajo distintas alternativas de manejo
(Asociación Argentina de Ecología, 2016-12)Los “pajonales” de Panicum prionitis (“paja de techar”) son una de las comunidades de mayor extensión en las islas y el valle de inundación del río Paraná. Debido a sus tasas de crecimiento elevadas y a su baja calidad ... -
Anidamiento de paloma torcaza (Zenaida auriculata) en rastrojos de sorgo
(Universidad Nacional del Litoral, 2016-10)La paloma torcaza (Zenaida auriculata) es una de las especies de aves más co-munes y abundantes de Argentina, con gran capacidad de adaptación a los am-bientes modificados por el hombre. Un aspecto clave del éxito de esta ... -
Desarrollo de un método para evaluar el daño ocasionado por aves en cultivos comerciales de soja recién emergida = Development of a method for assessing damage caused by birds in sprouting soybean in commercial crops
