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 ... -
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 ... -
Molecular evidence of hybrid zones of cedrela (Meliaceae) in the yungas of northwestern Argentina
(2016)In the Yungas of Northwestern Argentina, three endangered species of Cedrela (C. angustifolia, C. saltensis, and C. balansae) follow altitudinal gradients of distribution with contact zones between them. We sampled 210 ... -
Leaflet trichome micromorphology in the Dolentes-Brevipedes taxonomic complex (Mimosa L., Mimosoideae)
(Tubitak Scientific & Technical Research Council, Turquía, 2016)We studied leaflets of 18 taxa of the genus Mimosa, specifically the Dolentes-Brevipedes taxonomic complex, focusing on micromorphology, type, shape, and density of trichomes. Within the nonglandular trichomes we described ... -

(Instituto de Botánica del Nordeste, 2016)En este trabajo se analizan datos de relevamientos etnobotánicos de especies de legumbres (Leguminosae) funcionales y nutracéuticas comercializadas en el área Metropolitana de Buenos Aires, Argentina. El estudio fue realizado ... -
Toxicities of glyphosate- and cypermethrin-based pesticides are antagonic in the tenspotted livebearer fish (Cnesterodon decemmaculatus)
(2016)Although pesticide contamination of surface waters normally occurs in the form of mixtures, the toxicity and interactions displayed by such mixtures have been little characterized until now. The present study examined ... -
SSRs, SNPs and DArTs comparison on estimation of relatedness and genetic parameters’ precision from a small half-sib sample population of eucalyptus grandis
(2016)Simple sequence repeats (SSR) are the most widely used molecular markers for relatedness inference due to their multi-allelic nature and high informativeness. However, there is a growing trend toward using high-throughput ... -
Characterization of glandular trichomes of Minthostachys verticillata “peperina” from northwest and central Argentina: relation with essential oil content
(2016)Minthostachys verticillata is an endemic species in Argentina that shows higher contents of essential oils (EO %, v/w) in plants from the central area than in those from the northwest. Although the reason for this difference ... -
El Jardín Botánico Arturo E. Ragonese (JBAER): miradas a través del tiempo, realidad y prospectiva
(Ediciones INTA, 2016)Esta publicación sobre el Jardín Botánico Arturo E. Ragonese, además de ser la primera, se hace con el fin de mostrar la historia, el acervo y las actividades que lleva a cabo el mismo y destacar su potencialidad como una ... -
Intraspecific variation in essencial oil composition of A.N. the medicinal plant Lippia integrifolia (verbenaceae), evidence for five chemotypes
(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. ... -
Cambios en el uso del suelo y sus efectos a diferentes escalas espaciales y temporales sobre la diversidad de aves en el Bajo Delta del río Paraná
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2016-03)Las actividades humanas han modificado una gran proporción de la superficie terrestre. Sus impactos son extensos en particular sobre la biodiversidad y los bienes y servicios que proveen los ecosistemas. Los humedales son ... -
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 ... -
Supplementary Material Douglas-fir data [Conjunto de datos]
(2016-10)Supplementary information of the three Douglas-fir trials, family numbers, and pedigree data including identity information of trees, fathers, and mothers of the paper entitled: Identification and joint modeling of competition ... -
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 ... -
