An improved translational approach to studying persistence‐strengthening effects of differential reinforcement of alternative behavior

Journal of the Experimental Analysis of Behavior, Volume 126, Issue 1, July 2026.
Abstract Translational research investigating traditional differential reinforcement of alternative behavior (DRA) suggests that such procedures increase the persistence of target behavior relative to when the alternative behavior is first reinforced in a separate context prior to instigating the differential reinforcement procedure. One shortcoming of

Spatial and temporal variation in survival of female wild turkeys

The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
We monitored 370 female wild turkeys across North Carolina's 3 ecoregions from 2020‐2022 to understand factors influencing their survival. Female survival varied by ecoregion and behavior state, with the incubation period having the lowest survival rates. None of the land cover variables affected survival.

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.
