Genetic diversity and conservation status of managed vicuña (Vicugna vicugna) populations in Argentina por Anello, Melina, Daverio, Maria Silvana, Romero, Sandra Raquel, Rigalt, Francisco Antonio, Silbestro, Miriam Beatriz, Vidal Rioja, Lidia Beatriz, Di Rocco, Florencia

“…The vicuña (Vicugna vicugna) was indiscriminately hunted for more than 400 years and, by the end of 1960s, it was seriously endangered. At that time, a captive breeding program was initiated in Argentina by the National Institute of Agricultural Technology (INTA) with the aim of preserving the species. …”

Screening of bioactive compounds in lettuce: multivariate optimization of an ultrasound‑assisted solid–liquid extraction procedure por Lemos, Aldana Ayelén, Soto Vargas, Verónica Carolina, Wuilloud, Rodolfo Germán, Gonzalez, Roxana Elizabeth

“…Both extraction methods successfully extract diferent phytochemicals by reducing the volume of solvent, sample mass, and extraction time compared to previously reported methods. The results obtained showed a signifcant variability in the content of phytochemicals; therefore, it could be estimated that the diferent cultivars of lettuce evaluated will exhibit diferent benefcial health efects.…”

Use of UVC radiation as a postharvest stressor to increase phenolic compounds concentration and antioxidant status in purple, orange, and white carrots por Valerga, Lucia, Gonzalez, Roxana Elizabeth, Mauricci, Mariano Tomas, Concellón, Analía, Cavagnaro, Pablo

“…Results revealed that the UVC radiation, the root color phenotype, the carrot genotype within a particular root color, the degree of root processing, the storage time, and the type and color of individual root tissues all influenced TP, HI, CGA, and AOX levels, but not anthocyanin content and composition. …”

Capacidad productiva de pastizales bajo plantaciones de distinta densidad de Eucalyptus globulus en el sudeste bonaerense = Productive capacity of grasslands under plantations of E... por Quiñones Martorello, Adriana, Uhalt, C., Petigrosso, Lucas, Sallesses, Leonardo Fabian, Fernandez, María Elena, Gyenge, Javier

“…Forage production in silvopastoral systems depends mainly on the level of radiation that reaches the herbaceous stratum and the ability of species to fix carbon (C) in their biomass and, at the same time, to respond positively to grazing. Thus, in the Estación Experimental Agropecuaria Balcarce, a factorial test of solar radiation (3 levels) x cut (3 levels) was proposed in Eucalyptus globulus plantations in order to have information that allows the development of management standards for silvopastoral systems based on forage production. …”

Reduction in acute bee paralysis virus Infection and mortality in honey bees (Apis mellifera) by RNA interference technology por Ferrufino, Cecilia Gabriela, Scannapieco, Alejandra Carla, Russo, Romina Maria, Gonzalez, Fernanda Noemi, Salvador, Ricardo, Dus Santos, Maria Jose

“…Bee survival was recorded over 10 days for all treatments, and samples were subsequently processed for viral quantification using quantitative real-time PCR. The oral administration of specific dsRNA reduced the viral replication curve, decreased the average viral loads and increased bee survival. …”
