Assessing the intraspecific osteological variation in the spottail shiner (Hudsonius hudsonius) (Cypriniformes: Leuciscidae)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Hudsonius hudsonius (Cypriniformes: Leuciscidae), commonly known as the spottail shiner, is a small cyprinoid fish species found across much of North America. H. hudsonius has traditionally been regarded as one of the most basal and plesiomorphic species among the notropin fishes, that is, fishes traditionally placed in or associated with the ...

Conditional and constitutive expression of a Tbx1-GFP fusion protein in mice. [PDF]

open access: yes, 2013
BACKGROUND: Velo-cardio-facial syndrome/DiGeorge syndrome (VCFS/DGS) is caused by a 1.5-3 Mb microdeletion of chromosome 22q11.2, frequently referred to as 22q11.2 deletion syndrome (22q11DS).

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

A New Genus of Miniaturized and Pug-Nosed Gecko from South America (Sphaerodactylidae: Gekkota) [PDF]

open access: yes, 2011
Sphaerodactyl geckos comprise five genera distributed across Central and South America and the Caribbean. We estimated phylogenetic relationships among sphaerodactyl genera using both separate and combined analyses of seven nuclear genes.

Osteohistology of the unusually fast‐growing theropod dinosaur Ceratosaurus

open access: yesJournal of Anatomy, EarlyView.
We report the histology of multiple elements attributed to four individuals of Ceratosaurus. We find that the histology and growth models corroborate previous reports of rapid tissue growth in the genus. Abstract Ceratosaurus is a large‐bodied non‐avian theropod dinosaur known from the Upper Jurassic Morrison Formation of North America and is ...

Semicircular canal morphology in Rodentia and its relationship to locomotion

open access: yesJournal of Anatomy, EarlyView.
Here, we present a selection of rodent inner ear 3D models in the lateral view, with rodents from seven locomotor categories (left to right: fossorial, semifossorial, semiaquatic, terrestrial, ricochetal, arboreal, and gliding). Semicircular canal (SCC) morphology, including radius of curvature and shape, can be differentiated between specialized forms
