A novel individual-tree mixed model to account for competition and environmental heterogeneity: a Bayesian approach
(Springer Heidelberg, 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 ...
Direct and Competition Additive Effects in Tree Breeding: Bayesian Estimation From an Individual Tree Mixed Model
(J D Sauerlanders Verlag, 2008-12)
An individual tree model with additive direct and competition effects is introduced to account for competitive effects in forest genetics evaluation. The mixed linear model includes fixed effects as well as direct and ...
Improving accuracy of breeding values by incorporating genomic information in spatial-competition mixed models
(Springer, 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 ...
Bayesian estimation of a surface to account for a spatial trend using penalized splines in an individual-tree mixed model
(National Research Council Canada-NRC Research Press, 2007-12)
Unaccounted for spatial variability leads to bias in estimating genetic parameters and predicting breeding values from forest genetic trials. Previous attempts to account for large-scale continuous spatial variation employed ...
Identification and joint modeling of competition effects and environmental heterogeneity in three Douglas-fir (Pseudotsuga menziesii var. menziesii) trials
(Springer Heidelberg, 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 ...
Modelos de crescimento em diâmetro de árvores individuais de Araucaria angustifolia (Bertol.) Kuntze na floresta ombrófila mista
(Universidade Federal de Santa MariaBRRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia Florestal, 2009-08-05)
This work aims at modeling the diameter growth for individual trees of Araucaria angustifolia, present in the Mixed Ombrophylous Forest at National Forest of São Francisco de Paula, northeast of Rio Grande do Sul. Therefore, ...
Genomic-based multiple-trait evaluation in Eucalyptus grandis using dominant DArT markers
(Elsevier Ireland, 2018-06)
We investigated the impact of combining the pedigree- and genomic-based relationship matrices in a multiple-trait individual-tree mixed model (a.k.a., multiple-trait combined approach) on the estimates of heritability and ...
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 ...
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 ...
