Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

The Anatomical Record, Volume 309, Issue 9, Page 2368-2394, September 2026.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...

The relationship between form and function of the carnivore mandible

The Anatomical Record, Volume 309, Issue 9, Page 2487-2506, September 2026.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

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

Journal of Anatomy, Volume 249, Issue 3, Page 587-603, September 2026.
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.

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

The Anatomical Record, Volume 309, Issue 8, Page 2124-2150, August 2026.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

Chromosome-level genome assembly for giant panda provides novel insights into Carnivora chromosome evolution

Genome Biology, 2019
Background Chromosome evolution is an important driver of speciation and species evolution. Previous studies have detected chromosome rearrangement events among different Carnivora species using chromosome painting strategies.

Spatial‐Scale Evolutionary Bias Sheds Light on the Latitudinal Diversity Gradient

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Using Escherichia coli as a model species, our experimental findings reveal that populations in high‐fitness‐gain geographic regions undergo rapid expansion, competitively excluding populations from low‐fitness‐gain regions. This results in adaptive evolution that is biased toward areas with higher fitness potential.

Twenty‐Year Progress in Landscape Genetics of Tetrapods

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Geographic distribution of tetrapod landscape genetics between 2003 and 2025. ABSTRACT Landscape genetics, an interdisciplinary field integrating population genetics, landscape ecology, and spatial analytical techniques, has progressed significantly over two decades, yet systematic reviews of its application to tetrapods remain limited. Here, we review
