What Goes First? Effects of Starvation on the Body Condition of a Neotropical Dung Beetle

Entomologia Experimentalis et Applicata, EarlyView.
We investigated how prolonged starvation affects key physiological traits in the dung beetle Dichotomius bos. Prolonged starvation leads to significant reductions in body dry mass and fat reserves, while muscle mass remains unchanged. These findings indicate that dung beetles prioritize the maintenance of locomotor muscles while mobilizing stored ...

3D morphological analysis of age and sex‐related changes in human cortical bone remodeling spaces using micro‐CT

Journal of Anatomy, EarlyView.
This study investigates human cortical bone remodeling space morphology and its relationship with age and sex using micro‐CT imaging. Remodeling space morphology exhibits great inter‐ and intraindividual variation. Its dimensions decrease with increasing age, but do not differ between sexes.

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 ...

Architecture of lower leg muscles in children: Reference curves and potential mechanisms of growth

Journal of Anatomy, EarlyView.
Muscle architecture (physiological cross‐sectional area, fascicle lengths and pennation angle) was measured from multimodal MRI scans of the lower legs of 197 children aged ≤15 years. We showed that lower leg muscle volumes (product of PCSA and fascicle length) increase primarily through increases in PCSA (transverse growth) rather than increases in ...

MRI‐based, 3D analysis of Achilles tendon longitudinal strain under passive loading reveals limitations in conventional 2D measurement

Journal of Anatomy, EarlyView.
Graphical overview of 2D and 3D length measurements of the free Achilles tendon. The figure also illustrates how the typical distal morphology of the soleus muscle affects 2D measurement. Abstract Quantifying strain in the free Achilles tendon (ATF) is essential for understanding its mechanical function, yet existing in vivo studies report inconsistent

Comparative functional morphological study of the tarsal joint mobility in artiodactyls and perissodactyls in light of astragalar morphological differences

Journal of Anatomy, EarlyView.
This study investigated how variations in the shape of the astragalus affect tarsal joint behavior, using CT scans. In artiodactyls with a double‐pulley astragalus, the calcaneus shifted plantarly during plantarflexion. This suggests the movement increases hindlimb functional length and contributes to enhanced running speed.
