Understanding the spacing of placodes in the eye: A comparative study across age and species
The Anatomical Record, EarlyView.Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

EXPERIMENTAL MATURATION OF FEATHERS: IMPLICATIONS FOR INTERPRETATIONS OF FOSSIL FEATHERS
, 2020 Exceptionally preserved fossil feathers and feather-like integumentary structures provide valuable insights into the early evolution of feathers and flight, but taphonomic biases often make interpretations at the microstructural and ultrastructural ...

Cardiac morphological and morphometric analysis of Ardea alba
The Anatomical Record, EarlyView.Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Fascicle measurement methods do result in lengths that are significantly different
The Anatomical Record, EarlyView.A recent comparison of the most prevalent methods for measuring fascicles, in situ measurement versus chemical digestion, concluded that the measurements are indistinguishable based on data from different conspecific individuals. However, our study of contralateral muscles of the same individuals shows that the methods clearly result in statistically ...

The Anatomical Record, EarlyView.Histological structure of esophagus. Abstract The aim of this study was to conduct a comparative evaluation of the histological and histochemical organization of the esophagus in two avian species with different feeding ecologies. A total of 6 individuals were used for this purpose (3 storks, 3 common buzzards).

Animal Research and One Health, EarlyView.ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.

Animal Research and One Health, EarlyView.Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.
