Nanostructured voltammetric sensor for ultra-trace anabolic drug determination in food safety field
(2013-11)A sensitive electrochemical sensor for clenbuterol (CL) determination in bovine urine samples was designed. This drug was originally developed for the treatment of respiratory pathologies. However, in the livestock industry, ... -
Impacts of population structure and analytical models in genome-wide association studies of complex traits in forest trees: a case study in Eucalyptus globulus
(Plos One, 2013-11-25)The promise of association genetics to identify genes or genomic regions controlling complex traits has generated a flurry of interest. Such phenotype-genotype associations could be useful to accelerate tree breeding cycles, ... -
Host selection, oviposition behaviour and leaf traits in a specialist willow sawfly on species of Salix (Salicaceae)
(Wiley, 2013-12)Plant genotype influences plant–herbivore interactions by affecting insect attraction, acceptance and development. Here we linked oviposition behaviour of the specialist willow sawfly Nematus oligospilus Förster (Hymenoptera: ... -
An assessor-specific Bayesian multi-threshold mixed model for analyzing ordered categorical traits in tree breeding
(Springer, 2013-12)Many traits of biological interest in tree breeding are assessed using more than two ordered discrete categories. These scores have a more or less arbitrary and subjective assignment by the assessors, which could lead to ... -
Tecnología de procesos en la generación de biogás a partir de subproductos agrícolas
(2014)Durante la última década hemos sido testigos de un crecimiento exponencial del empleo de diferentes fuentes de biomasa con fines energéticos comerciales. Esta tendencia fuertemente apoyada por el ambientalismo se ha ... -

Synergy between glyphosate- and cypermethrin-based pesticides during acute exposures in tadpoles of the common South American Toad Rhinella arenarum
(2014)The herbicide glyphosate and the insecticide cypermethrin are key pesticides of modern management in soy and corn cultures. Although these pesticides are likely to co-occur in ephemeral ponds or aquatic systems supporting ... -
Conservation and management of birds in agroecosystems in east-central Argentina
(University of Georgia, Estados Unidos, 2014)Bird conservation, and associated ecosystem services, is challenged by agricultural intensification and expansion. In Pampas grassland and Espinal forest ecoregions of east-central Argentina these processes have been ongoing ... -
