Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

open access: yesThe Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

open access: yesThe Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

open access: yesThe Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

open access: yesAnimal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Indole‐3‐Acetic Acid Protects Bovine Hepatocytes Against Palmitic Acid‐Induced Lipid Accumulation and ER Stress Through SIRT3

open access: yesAnimal Research and One Health, EarlyView.
Cows with ketosis during the perinatal period often experience damage to the liver, a core metabolic organ, thereby exacerbating the disease's inherent vicious cycle. This study indicates that serum 3‐IAA concentrations were reduced in ketotic cows and show a significant negative correlation with hepatic TG content.
