Body size, functional form and environmental correlates of maximum longevity in marine‐occurring fishes

open access: yesJournal of Fish Biology, EarlyView.
Abstract Maximum longevity varies widely among marine‐occurring fishes, but the form of its relationship with body size and the contribution of broad environmental gradients remain uncertain. We analysed 757 species, using maximum length as the primary size metric and completed mass only in sensitivity analyses.

Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 558-574, April 2025.
Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all

Post‐hatching development of the remote‐tactile bill‐tip organ in precocial shorebirds (Scolopacidae)

open access: yesJournal of Anatomy, EarlyView.
Juvenile scolopacid shorebirds possess well‐developed osteological correlates of tactile bill‐tip organs, indicating sensory systems for remote‐touch foraging are present from early life. Ontogenetic changes in bill‐tip morphology suggest ecological specialisation and interspecific variation develop later, after fledging in these highly precocial ...

The variability of giraffe skull morphology

open access: yesJournal of Anatomy, EarlyView.
What does giraffe skull shape tell us about their development and evolution? Abstract Giraffe (Giraffa spp.) are among the most unique and charismatic extant animals, largely due to their distinct morphology. The evolutionary and developmental origin of ossicones is a key factor in giraffid biology, yet other features building their characteristic head

Computed tomography reveals the endocranial anatomy of Crocodylia: Implications for phylogenetic relationships and ecomorphological convergence across Crocodylomorpha

open access: yesJournal of Anatomy, EarlyView.
The evaluation of the endocranial anatomy of 43 crocodylian species reveals several differences, including variation in the curvature of the encephalic endocast, the size of the endosseous labyrinth and paratympanic sinuses, and the presence of additional snout sinuses.

Growing together: Developmental integration and modularity in the human talus–calcaneus complex

open access: yesJournal of Anatomy, EarlyView.
This study investigates morphological integration and trabecular bone development in the human talus–calcaneus complex during postnatal ontogeny. The two bones exhibit strong integration throughout development, with differing bone volume fraction trajectories presumably reflecting their distinct functional roles during bipedal gait acquisition ...

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds

open access: yesJournal of Anatomy, EarlyView.
The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Drug Partitioning and Solvation Environments in Lipid Bilayers

open access: yes, 2004
The main goal of this research project was to investigate various factors influencing solute partitioning and solvation in lipid bilayer membranes using liposomes as biomembrane models and applying a combination of spectroscopic and capillary ...

From sagittal to sprawled: Clavicular co‐option and the evolution of forelimb mechanics in talpines

open access: yesJournal of Anatomy, EarlyView.
Forelimb posture in Eulipotyphla divides into sagittal and sprawled groups with distinct scapular and clavicular orientations. First true rib strength scales with body mass, reflecting vertical ground reaction forces, whereas clavicular strength reflects differences in medially directed forces on the pectoral girdle, especially pronounced in highly ...

Skeletons of swiftly swimming sharks: Three‐dimensional analysis of lamniform vertebral morphology and mineral architecture

open access: yesJournal of Anatomy, EarlyView.
We examined morphology, 3D arrangement, and mineral amount in cartilaginous vertebrae from four lamniform shark families (Alopiidae, Carchariidae, Cetorhinidae, and Lamnidae). We identified family‐specific mineralization trends, and regional patterning of structures along the column.
