Estimating offsets for avian displacement effects of anthropogenic impacts [PDF]

, 2019
Biodiversity offsetting, or compensatory mitigation, is increasingly being used in temperate grassland ecosystems to compensate for unavoidable environmental damage from anthropogenic developments such as transportation infrastructure, urbanization, and ...

Pitfalls and Remedies for Cross Validation with Multi-trait Genomic Prediction Methods. [PDF]

, 2019
Incorporating measurements on correlated traits into genomic prediction models can increase prediction accuracy and selection gain. However, multi-trait genomic prediction models are complex and prone to overfitting which may result in a loss of ...

Genomic breeding value estimation using nonparametric additive regression models [PDF]

Genetics Selection Evolution, 2009
Genomic selection refers to the use of genomewide dense markers for breeding value estimation and subsequently for selection. The main challenge of genomic breeding value estimation is the estimation of many effects from a limited number of observations. Bayesian methods have been proposed to successfully cope with these challenges.

Application of Genomic Data for Reliability Improvement of Pig Breeding Value Estimates

Animals, 2021
Replacement pigs’ genomic prediction for reproduction (total number and born alive piglets in the first parity), meat, fatness and growth traits (muscle depth, days to 100 kg and backfat thickness over 6–7 rib) was tested using single-step genomic best ...

EM algorithm for Bayesian estimation of genomic breeding values [PDF]

BMC Genetics, 2010
In genomic selection, a model for prediction of genome-wide breeding value (GBV) is constructed by estimating a large number of SNP effects that are included in a model. Two Bayesian methods based on MCMC algorithm, Bayesian shrinkage regression (BSR) method and stochastic search variable selection (SSVS) method, (which are called BayesA and BayesB ...

Assessment of Efficiency of Breeding Methods in Accelerating Genetic Gain in Rice

Agronomy
The pedigree, bulk, and single-seed descent-based rapid generation advance methods are commonly practiced breeding methods in rice. But the efficiency of these breeding methods in enhancing genetic gain has not been investigated yet.

Genomic Prediction for 25 Agronomic and Quality Traits in Alfalfa (Medicago sativa)

Frontiers in Plant Science, 2018
Agronomic and quality traits in alfalfa are very important to forage industry. Genomic prediction (GP) based on genotyping-by-sequencing (GBS) data could shorten the breeding cycles and accelerate the genetic gains of these complex traits, if they ...

Reliabilities of genomic estimated breeding values in Danish Jersey

Animal, 2012
In order to optimize the use of genomic selection in breeding plans, it is essential to have reliable estimates of the genomic breeding values. This study investigated reliabilities of direct genomic values (DGVs) in the Jersey population estimated by three different methods. The validation methods were (i) fivefold cross-validation and (ii) validation
