Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs
The Anatomical Record, EarlyView.Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

Synchrotron radiation reveals the identity of the large felid from Monte Argentario (Early Pleistocene, Italy) [PDF]
, 2018 We describe here a partial skull with associated mandible of a large felid from Monte Argentario, Italy (Early Pleistocene; ~1.5 million years). Propagation x-ray phase-contrast synchrotron microtomography of the specimen, still partially embedded in the

The Anatomical Record, EarlyView.This work brings new information on the sexual characteristics of the crocodile shark (Pseudocarcharias kamoharai) exploring the pelvic fin musculature, as well as the siphon sac and the musculature and skeleton of the clasper. Our paper is the first to point out clearly the sexual dimorphism related exclusively to the pelvic fin musculature in males ...

Maxillary dentigerous cyst and supernumerary tooth. Is it a frequent association? [PDF]
, 2015 Dentigerous cysts, also known as follicular cysts, are a relatively common pathology in our field. They are associated with unerupted or semi-erupted teeth and are usually not related to supernumerary teeth. OBJECTIVE: To describe a dentigerous cyst case

Loss, persistence and reversal of phenotypic traits
Biological Reviews, EarlyView.ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...
