Histomorphology of bursa of Fabricius: effects of stock densities on commercial broilers

Brazilian Journal of Poultry Science, 2006
During the past few years, there has been considerable interest on the effects of stocking density on broiler behavior and immunity. Stress may cause immunodeficiency by affecting cell and humoral responses, as well as body weight decrease, and foot-pad ...

Meta‐Analysis of the Efficacy of Spirulina Intervention in Mitigating the Negative Impact of Heat Stress on Production Physiology and Health Indices of Broilers

Journal of Animal Physiology and Animal Nutrition, Volume 110, Issue 1, Page 23-34, January 2026.
ABSTRACT There is an increasing number of published studies on the effect of spirulina (an aquatic plant known for its high nutritional value and potential health benefits) intervention on productivity and health of heat‐stressed broilers. However, the effect of spirulina intervention on the performance of broilers exposed to heat stress is poorly ...

Phylogeny, systematics and evolution of mimicry patterns in Neotropical limenitidine butterflies

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
The most comprehensive phylogeny for Adelpha reveals that it is not monophyletic, supporting the description of the new genus Adelphina for the alala‐group. The rate of mimicry evolution increases towards the tropics, consistent with the hypothesis of stronger biotic interactions near the equator.

Complementary genomic and morphological data elucidate the phylogeny of obscure darkling beetles (Blaptinae: Platynotini: Eurynotina)

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
First comprehensive phylogenomic study of subtribe Eurynotina using a combined dataset of 499 nuclear loci, 12 mitochondrial loci and 91 morphological characters covering all genera and species groups is presented. Eurynotina is monophyletic and genera within are redefined based on reassessment of old characters, generation of new characters, and ...

Molecular and Functional Insights Into the Avian Gut Microbiota: Roles in Health, Disease Resistance, and Microbiome Modulation

Advanced Gut &Microbiome Research, Volume 2026, Issue 1, 2026.
The avian gut microbiota constitutes a complex, multiphyla ecosystem that critically shapes host physiology, immune function, disease resistance, and antimicrobial resistance dynamics. Bacteria, archaea, fungi, and viruses collectively regulate nutrient metabolism, mucosal barrier integrity, and immunological maturation, whereas dysbiosis increases ...
