Measuring sexual dimorphism in human faces

Journal of Anatomy, EarlyView.
CVA outperforms regression scoring when measuring sexual dimorphism in human faces, allowing for more accurate classification and shape reconstruction. Method selection has a significant impact on findings, necessitating a reevaluation of previous claims linking facial masculinity to traits such as height.

Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

Journal of Anatomy, EarlyView.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...

Does ulnar curvature covary with locomotion and substrate use in cercopithecids?

Journal of Anatomy, EarlyView.
This study investigates ulnar curvature in cercopithecids in relation to locomotor behaviors, introducing an analysis of anteroposterior and mediolateral curvature, using geometric morphometric on 167 specimens (23 species). Although the two curvatures distinguish arboreal and terrestrial quadrupeds, their moderate covariation suggests that they ...

Hoffmann's two‐toed sloth I: Complete myology in the thoracic limb of Choloepus (Pilosa: Xenarthra)

Journal of Anatomy, EarlyView.
Two‐toed sloths use their thoracic limbs for more frequent and prolonged suspensory support than three‐toed sloths and accordingly demonstrate myological traits consistent with stability of the pectoral girdle, enhanced flexor force/torque applied at the elbow joint, and grip on the support.
