Polymorphism of the Gonadotropin‐Releasing Hormone Receptor Gene and Its Association With Production Traits in Isfahani Native Hens

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This research was conducted to identify genetic polymorphisms of the GNRHR gene on Isfahan native hen traits and their relationship with production traits. For this purpose, blood was taken, DNA was extracted, the target fragment was amplified and directly sequenced, and finally it was blasted with the reference gene in NCBI.

Spectromicroscopy Analysis of Chicken Egg Shells

X-Ray Spectrometry, Volume 55, Issue 4, Page 587-596, July/August 2026.
ABSTRACT Chicken egg shells, taken from farm and backyard eggs of different suppliers from different regions in Brazil were collected for chemical/structural analysis, in order to try to find if there is a relation between egg shells composition and the type of production (farm or backyard), the egg shell color and the region of production.

Temperature Impacts on Mating and Oviposition of the Emerald Ash Borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae)

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 715-724, July 2026.
The emerald ash borer (EAB), Agrilus planipennis, threatens ash trees in North America and Europe. To assess the role of temperature on EAB reproduction, we reared adults at one of four temperatures (12°C, 15°C, 18°C, and 21°C) and measured reproductive success.

Egg Spots Are Important Cues for Egg Recognition in Barn Swallows

Ecology and Evolution
Egg recognition is one of the most common strategies utilized by host birds to combat brood parasitism. Eggshell surface features (e.g., eggshell color and spots) are important cues for host egg recognition, enabling avian hosts to recognize and reject ...
