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 ... -
Occupancy of avian foraging guilds in soybean fields and borders in Entre Ríos, Argentina: responses to vegetation structure and prey resources
(BMC, 2020-12)Reconciling agriculture and biodiversity conservation is a challenge given the growing demand for agricultural products. In recent decades, Argentina has witnessed agricultural expansion and intensification affecting ... -
On-farm assessment of yield and quality traits in durum wheat
(Wiley, 2023-08-15)Durum wheat is key source of calories and nutrients for many regions of the world. Demand for it is predicted toincrease. Further efforts are therefore needed to develop new cultivars adapted to different future scenarios. ... -
On-farm impact on bread wheat quality under different management practices: a case study in the Yaqui Valley
(Wiley, 2023-03-24)Continuous development of new wheat varieties is necessary to satisfy the demands of farmers, industry, and consumers. The evaluation of candidate genotypes for commercial release under different on-farm conditions is a ... -
Optimizing a regional white spruce tree improvement program: SNP genotyping for enhanced breeding values, genetic diversity assessment, and estimation of pollen contamination
(MDPI, 2023-11-01)The utilization of genotyping has gained significant popularity in tree improvement programs, aiding in enhancing the precision of breeding values, removing pedigree errors, the assessment of genetic diversity, and evaluating ... -
Partitioning the effects of habitat loss hunting and climate change on the endangered Chacoan peccary
(Wiley, 2023-04-04)Aim: Land-use change and overexploitation are major threats to biodiversity, and cli mate change will exert additional pressure in the 21st century. Although there are strong interactions between these threats, our ... -
Performance of alternative spatial models in empirical Douglas-fir and simulated datasets
(Springer, 2019-05-13)Based on an empirical dataset originating from the French Douglas-fir breeding program, we showed that the bidimensional autoregressive and the two-dimensional P-spline regression spatial models clearly outperformed the ... -
Performance of Pinus elliottii, Pinus caribaea, their F1, F2 and backcross hybrids and Pinus taeda to 10 years in the Mesopotamia region, Argentina
(Springer, 2013-03)Performances of Pinus taxa were studied to 10 years of age in two trials in each of Misiones and Entre Ríos provinces across the Mesopotamia region of Argentina. Taxa comprised 22 populations from sources in Argentina, ... -

Precipitation is the main axis of tropical phylogenetic turnover across space and time
(BioRxiv, 2022-05-31)Early natural historians – Compte de Buffon, von Humboldt and De Candolle – established ecology and geography as two principal axes determining the distribution of groups of organisms, laying the foundations for biogeography ... -
Prediction of the extractives content of Eucalyptus globulus wood using NIRbased PLS-R models. Influence of spectral range and preprocessing on the percentage of outliers detected
(Taylor & Francis, 2022-07-08)Eucalyptus globulus is an important pulpwood source due to favorable wood characteristics, including low extractive content. However, there is significant tree-to-tree variation that can be exploited in breeding. This ... -
