(2016-02)The aerial parts of Lippia integrifolia (incayuyo) are widely used in northwestern and central Argentina for their medicinal and aromatic properties. The essential oil composition of thirty-one wild populations of L. ... -
Genetic and physical mapping of the earliness perse locus Eps - Am1 in Triticum monococcum identifies early flowering 3 (ELF3) as a candidate gene
(2016-07)Wheat cultivars exposed to optimal photoperiod and vernalization treatments still exhibit differences in heading time. This variation, known as earliness per se (Eps), is important for the fine-tuning of flowering and the ... -
Identification and joint modeling of competition effects and environmental heterogeneity in three Douglas-fir (Pseudotsuga menziesii var. menziesii) trials
(2016-12)(Co)variance matrices for the assumed model, and thus the specification of the dispersion parameters, should take into account both the negative competition and the positive spatial correlations. In this context, we applied ... -
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: ... -
Single-step BLUP with varying genotyping effort in open-pollinated Picea glauca
(2017-03)Maximization of genetic gain in forest tree breeding programs is contingent on the accuracy of the predicted breeding values and precision of the estimated genetic parameters. We investigated the effect of the combined use ... -
Leaf venation pattern to recognize austral South American medicinal species of “cow's hoof” (Bauhinia L., Fabaceae)
(Elsevier, 2017-04)The leaves extracts of some species of Bauhinia L. s.l. are consumed to treat diabetes, inflammation, pains and several disorders in traditional medicine in austral South America. Despite its wide use and commercialization, ... -
Deforestation and cattle expansion in the Paraguayan Chaco 1987–2012
(2017-04)The dry forests of Latin America are among the most dynamic deforestation frontiers in the world and are important carbon and biodiversity reservoirs. Our knowledge on the spatial patterns of deforestation and its proximate ... -
Morphological and molecular identification of the invasive Xylosandrus crassiusculus (Coleoptera: Curculionidae: Scolytinae) and its South American range extending Into Argentina and Uruguay
(2017-05)The occurrence of the exotic “granulate ambrosia beetle” Xylosandrus crassiusculus (Motschulsky) in Argentina and Uruguay is reported for the first time, documenting expansion in South America. Morphological characters are ... -
Carbon emissions from agricultural expansion and intensification in the Chaco
(Wiley, 2017-05)Carbon emissions from land‐use changes in tropical dry forest systems are poorly understood, although they are likely globally significant. The South American Chaco has recently emerged as a hot spot of agricultural expansion ... -
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 ... -
Assessing wildfire exposure in the Wildland-Urban Interface area of the mountains of central Argentina
(2017-07-01)Wildfires are a major threat to people and property in Wildland Urban Interface (WUI) communities worldwide, but while the patterns of the WUI in North America, Europe and Oceania have been studied before, this is not the ... -
Improving accuracy of breeding values by incorporating genomic information in spatial - competition mixed models
(2017-10)Climate change and the increasing demand for sustainable energy resources require urgent strategies to increase the accuracy of selection in tree breeding (associated with higher gain). We investigated the combined pedigree ... -
Accumulation of current-use pesticides, cholinesterase inhibition and reduced body condition in juvenile one-sided livebearer fish (Jenynsia multidentata) from the agricultural Pampa region of Argentina
(2017-10)The aim of this study was to characterize the level and nature of the pesticide contamination received by one-sided livebearer fish (Jenynsia multidentata) from a watercourse situated within the main agricultural region ... -
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 ... -
