Histological analysis of incremental markings and crown growth characteristics in mandibular first molars of the red fox, Vulpes vulpes (Canidae, Mammalia)

Journal of Anatomy, EarlyView.
This paper histologically analyzed incremental markings in dental enamel of red fox and grey wolf. Our results demonstrate that previous studies have misidentified these markings, which led to miscalculation of dental growth parameters. Abstract The present study analyzed incremental markings in the enamel of eight mandibular first molars (M1) of red ...

Morphofunctional effects of captivity on the microanatomy of the talus bone in a wild ungulate (Sus scrofa)

Journal of Anatomy, EarlyView.
Our study explores the plastic changes induced by captivity on the microanatomy of the talus of wild boars, revealing denser bone with tighter trabecular networks but a lower relative maximum thickness of compact bone. These plastic adaptations can serve to detect early processes of domestication in the archaeological record.

The immediate effects of weaning stress on the hypothalamus‐pituitary‐adrenal alteration of newly weaned piglets

Journal of Animal Physiology and Animal Nutrition, 2019
AbstractThis study was conducted to examine the effects of weaning stress on gene expression of specific markers in hypothalamus‐pituitary‐adrenal (HPA) axis and neuronal activity in the newly weaned piglets. Twelve 28‐days‐old, newly weaned crossbred (Landrace × Yorkshire × Duroc) male piglets from 6 l (2 piglets/l) were randomly categorized into two ...
