Endogamia, fixação de alelos e limite de seleção em populações selecionadas por métodos tradicionais e associados a marcadores moleculares Inbreeding, alleles fixation and selection limit in populations under traditional or marker assisted selection methods

Revista Brasileira de Zootecnia, 2007
Objetivou-se avaliar o coeficiente de endogamia, a fixação de alelos e o limite de seleção em populações selecionadas durante 20 gerações. A seleção foi baseada nos valores genéticos preditos pelo BLUP clássico (BLUP) e pelo BLUP marcadores (BLUPM) e na ...

A Multivariate Mixed‐Effects Regression Framework for Ground Motion Modeling: Integrating Parametric and Machine Learning Approaches

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1811-1827, 25 July 2026.
ABSTRACT Multivariate ground motion models (GMMs) that capture the correlation between different intensity measures (IMs) are essential for seismic risk assessment. Conventional GMMs are often developed using a two‐stage approach, where separate univariate models with predefined functional forms are fitted first, and correlation is addressed in a ...

Forecasting New Employment Using Nonrepresentative Online Job Advertisements With an Application to the Italian and EU Labor Market

Journal of Forecasting, Volume 45, Issue 4, Page 1529-1558, July 2026.
ABSTRACT Using online job advertisement data improves the timeliness and granularity depth of analysis in the labor market in domains not covered by official data. Specifically, its variation over time may be used as an anticipator of official employment variations.

Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 508-523, July 2026.
ABSTRACT In autochthonous livestock breeds with small populations, such as the Rubia Galega from Galicia (Spain), mating between relatives is common and can lead to inbreeding depression. Genomic inbreeding coefficients were estimated for 4984 animals using ~63,000 SNPs to assess inbreeding depression in four key traits: age at first calving (AFC) with

Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 496-507, July 2026.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus, especially Nellore cattle, remain limited.

Use of Cluster Analysis for Identifying Metafounders

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 535-559, July 2026.
ABSTRACT In the metafounder approach, the relationship matrix of metafounders, Γ is used to transfer information on relationships between pedigree founders into the numerator relationship matrix A, creating matrix AΓ. Commonly metafounders are defined based on the available information of the animal (e.g., country, sex, breed) similar to unknown parent

Stage-wise selection of tropical wheat populations using univariate and multivariate BLUP models

Crop Breeding and Applied Biotechnology
Plant breeding programs often involve several segregating populations that must be selected for multiple traits. This study aimed to identify tropical wheat populations combining earliness and high grain yield (GY) using univariate and multivariate best ...
