Functional morphology of trabecular bone in the calcaneus of African apes

Journal of Anatomy, EarlyView.
Pan exhibits significantly higher calcaneal tuberosity trabecular thickness (Tb.Th) and bone volume fraction (BV/TV) than Gorilla, potentially reflecting higher triceps surae forces for vertical climbing. Both taxa have significantly higher Tb.Th and BV/TV in the anterior calcaneus; the difference is exaggerated in Gorilla, potentially reflecting ...

The variability of giraffe skull morphology

Journal 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

Three-dimensional magnetic resonance imaging-based registration techniques and statistical shape analysis for knee osteoarthritis

Scientific Reports
The efficacy of three-dimensional (3D) magnetic resonance imaging (MRI)-based registration techniques in femur models of osteoarthritis (OA) with respect to OA severity was investigated in this study.

Agro-morphological and molecular characterization of Argentine maize (Zea mays L.) landraces of ‘Cristalino Colorado’ race

Genetic Resources
Despite the high variability of Argentine maize (Zea mays L.) landraces, they are scarcely used by breeders due to the limited knowledge available about the genetic merit of these materials.

Phenotypic integration and the organization of discrete facial variation

Journal of Anatomy, EarlyView.
Integration patterns shape the prevalence of discrete facial trait combinations. Abstract Facial morphology results from coordinated developmental and evolutionary processes that produce structured patterns of covariation among traits. Therefore, individual faces reflect integrated anatomical configurations rather than collections of isolated traits ...

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

Journal 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 ...

Annual Variability of Wing Morphology in Culex sitiens Wiedemann (Diptera, Culicidae) Mosquito Vectors from the Coastal Area of Samut Songkhram Province, Thailand

Journal of Parasitology Research, 2019
Culex sitiens Wiedemann (Diptera, Culicidae) is a mosquito vector that is found in coastal areas. Effective control of mosquitoes requires knowledge of the biology, ecology, and behavior of the vector as well as of various other aspects, including its ...

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

Journal 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.

Genetic and Environmental Influences on Dental Arch Shape During Development: A Longitudinal Twin Study

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This study aimed to determine the relative contributions of genetic and environmental factors to phenotypic variations of dental arch shape from the primary to permanent dentition stages. Materials and Methods Maxillary and mandibular digital models of 188 twin pairs (90 monozygotic and 98 dizygotic) in the primary dentition stage ...

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

The Anatomical Record, Volume 309, Issue 9, Page 2476-2486, September 2026.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...
