A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

open access: yesThe Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

open access: yesThe Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Cardiac morphological and morphometric analysis of Ardea alba

open access: yesThe 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 ...

Three‐dimensional digital analysis of musteloid masticatory muscle architecture

open access: yesThe Anatomical Record, EarlyView.
Musteloids span an enormous breadth of dietary modes within a single superfamily. In this study, we utilize digital dissection techniques to reconstruct the internal 3D anatomy of muscles within the musteloid feeding apparatus, and explore how dietary specializations might alter the size, orientation, and curvature of fascicles therein.

Evolution and biological characteristics of the circulated H8N4 avian influenza viruses

open access: yesJournal of Integrative Agriculture
The circulating avian influenza viruses in wild birds have a high possibility of spillover into domestic birds or mammals at the wild bird–domestic bird or bird–mammal interface.

Balancing mechanics and metabolism: Elevational variation in the microanatomy of hummingbird flight muscle

open access: yesThe Anatomical Record, EarlyView.
Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.
