Bacillus velezensis strain NA16 shows high poultry feather-degrading efficiency, protease and amino acid production

Ecotoxicology and Environmental Safety
Isolated Bacillus velezensis strain NA16, which produces proteases, amino acids and the transcription levels of different keratinolytic enzymes and disulfide reductase genes in whole gene sequencing, was evaluated during feather degradation.

Trade‐offs in avian parental care: a review of theory and meta‐analysis of brood size manipulations

Biological Reviews, EarlyView.
ABSTRACT The selective forces shaping parental care have been studied for over 50 years. While theoretical and experimental work has yielded qualitative progress, the large body of empirical work testing predictions about parental investment based on life‐history trade‐offs has yet to be synthesized.

Building phenotypic character matrices for phylogenetic inference: exploration of 35 years of practice

Biological Reviews, EarlyView.
ABSTRACT Recent methodological development in phylogenetic inference has focused predominantly on molecular data. However, renewed interest in other data types, particularly morphological data, has followed from the increased recognition of the power of total evidence and tip‐dating approaches, including fossil data, for inference of time‐scaled trees ...

Global distribution of avian plumage coloration and patterning: the relative influence of climate, ecology, and sexual selection

Ecography, EarlyView.
Animal coloration exhibits substantial biogeographic variation, reflecting complex adaptations to both abiotic and biotic environments. Although the evolutionary mechanisms underlying avian plumage coloration have been widely studied, geographic variation in plumage patterning has received far less attention.

Identification and Characterisation of Alternative Splice Variants of Hoxb9 and Their Correlation with Melanogenesis in the Black-Boned Chicken

Brazilian Journal of Poultry Science
Homeobox B9 (HOXB9) gene has been demonstrated to be associated with melanogenesis in chicken plumage by high-throughput RNA sequencing. In this study, we cloned and characterised HOXB9 in black-boned chickens.

A uterine‐centric view of reproductive senescence: Genetic insights into late‐life performance in laying hens

iMetaOmics, EarlyView.
This study identifies uterus weight as a heritable (h2 = 0.45) intermediate phenotype that independently associates with late‐life egg production and eggshell quality in aged laying hens. Genome‐wide association study (GWAS) reveals a genome‐wide significant locus on chromosome 3 and suggestive loci on chromosome 11 for uterus weight, mediation ...
