Assessing habitat suitability for black grouse broods at the bioregional scale

Wildlife Biology, EarlyView.
The black grouse Lyrurus tetrix, a galliform species emblematic of the European Alps, is currently threatened by habitat change, particularly given the closure of heathland linked to the rising tree line at higher altitudes. The presence of heathlands in good ecological condition is, however, imperative for the species' reproduction.

Effects of Dietary Yellow Mealworm (Tenebrio Molitor) supplementation on meat and structural egg quality of different aged-laying hens

Poultry Science
Global poultry production faces dual pressures of sustainable protein scarcity and age-specific nutritional demands. Tenebrio molitor (TM) emerges as an eco-friendly alternative protein source, yet its differential effects across laying hen life stages ...

Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range‐restricted or threatened species

Wildlife Biology, EarlyView.
In the late‐20th century, golden and Bonelli's eagles suffered population declines on the Iberian Peninsula, partly due to human persecution. Habitat assessments – especially for Bonelli's eagles – always found or assumed strong associations with cliffs that provided nesting sites.

Spectromicroscopy Analysis of Chicken Egg Shells

X-Ray Spectrometry, EarlyView.
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.

Absolute scaling of small‐ and wide‐angle X‐ray scattering images recorded with short duration X‐ray pulses on a large area fiber‐taper X‐ray detector

Journal of Synchrotron Radiation, EarlyView.
An X‐ray scattering setup designed to capture small‐ and wide‐angle X‐ray scattering on a single, large area detector features a partially transmissive beamstop that facilitates non‐invasive recording of X‐ray beam position and intensity during acquisition of X‐ray scattering images.
