Ultra sensitive microfluidic immunosensor for determination of clenbuterol in bovine hair samples using electrodeposited gold nanoparticles and magnetic micro particles as bio-affinity platform
(Elsevier, 2013-03-15)In this article, we report the first integrated microfluidic immunosensor coupled to a screen-printed carbon electrode (SPCE) applied to determination of clenbuterol (CLB) in bovine hair samples. CLB is a member of the ... -
Essential oil chemotypes of Aloysia citrodora (Verbenaceae) in Northwestern Argentina
(Elsevier, 2017-10)Chemical biodiversity of essential oils of natural populations of Aloysia citrodora Palau (“lemon verbena”, “cedrón”) in Northwestern Argentina was assessed by collecting in the same sites through different years. A total ... -
De novo assembly and characterization of leaf transcriptome for the development of functional molecular markers of the extremophile multipurpose tree species Prosopis alba
(2013-10)Background: Prosopis alba (Fabaceae) is an important native tree adapted to arid and semiarid regions of north-western Argentina which is of great value as multipurpose species. Despite its importance, the genomic resources ... -
Cross transferability of SSR markers to endangered Cedrela species that grow in Argentinean subtropical forests, as a valuable tool for population genetic studies
(Elsevier, 2014-04)Species of Cedrela with a high economic value from Northwest and Northeastern Argentina are severely exploited. This work evaluates whether 51 nuclear SSRs, developed to study phylogenetically close species in the Meliaceae ... -
Effects of past and future land conversions on forest connectivity in the Argentine Chaco
(Springer, 2015-05)Context: Land-use change is the main driver of habitat loss and fragmentation worldwide. The rate of dry forest loss in the South American Chaco is among the highest in the world, mainly due to the expansion of soybean ... -
Mapping QTL for resistance to new virulent races of wheat stripe rust from two Argentinean wheat cultivars
(Crop Science Society of America, 2018)During the last two decades, new virulent and aggressive races of Puccinia striiformis Westend. f. sp. tritici (Pst) have spread worldwide, causing devastating epidemics and prompting the search for new sources of resistance ... -
Lectotipificaciones en Mimosa (Leguminosae) del sur de Sudamérica
(Sociedad Argentina de Botánica, 2018)Se procedió a realizar la lectotipificación de tres especímenes del género Mimosa L. que crecen en Argentina: M. obstrigosa Burkart, M. tandilensis Speg. y M. callosa var. longiracemosa Burkart. Se describe el procedimiento ... -
Anuran responses to spatial patterns of agricultural landscapes in Argentina
(2016-12)Context: Amphibians are declining worldwide and land use change to agriculture is recognized as a leading cause. Argentina is undergoing an agriculturalization process with rapid changes in landscape structure. Objectives: ... -
Chromosome studies in southern species of Mimosa (Fabaceae, Mimosoideae) and their taxonomic and evolutionary inferences
(2014-05)In this work, chromosome numbers and karyotype parameters of 36 taxa of the genus Mimosa were studied, especially from the southern South America center of diversification. Results support that x = 13 is the basic chromosome ... -
The potential impact of economic policies on future land-use conversions in Argentina
(2018)Agricultural expansion and intensification drive the conversion of natural areas worldwide. Scenarios are powerful tools to explore possible future changes in agricultural land use, how these may affect the environment, ... -
Future Land-Use Changes and the Potential for Novelty in Ecosystems of the United States
(2015-12)Rapid global changes due to changing land use, climate, and non-native species are altering environmental conditions, resulting in more novel communities with unprecedented species combinations. Understanding how future ... -
A novel individual-tree mixed model to account for competition and environmental heterogeneity: a Bayesian approach
(Springer, 2015-12)Negative correlation caused by competition among individuals and positive spatial correlation due to environmental heterogeneity may lead to biases in estimating genetic parameters and predicting breeding values (BVs) from ... -
Carotenoids gene markers for sweetpotato (Ipomoea batatas L. Lam): applications in genetic mapping, diversity evaluation and cross‑species transference
(Springer, 2014-04)Carotenoids play essential biological roles in plants, and genes involved in the carotenoid biosynthesis pathway are evolutionarily conserved. Orange sweetpotato is an important source of β-carotene, a precursor of vitamin ... -
Regulation of Zn and Fe transporters by the GPC1gene during early wheat monocarpic senescence
(2014-12)Background; During wheat senescence, leaf components are degraded in a coordinated manner, releasing amino acids and micronutrients which are subsequently transported to the developing grain. We have previously shown that ... -
The role of soybean production as an underlying driver of deforestation in the South American Chaco
(2017-07)South America’s tropical dry forests and savannas are under increasing pressure from agricultural expansion. Cattle ranching and soybean production both drive these forest losses, but their relative importance remains ... -
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, ... -
