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

Journal 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 ...

Inner ear morphology in the Atlantic molly Poecilia mexicana [PDF]

, 2011
Fishes show an amazing diversity in hearing abilities, inner ear structures, and otolith morphology. Inner ear morphology, however, has not yet been investigated in detail in any member of the diverse order Cyprinodontiformes.

Two new species of stone loaches of the genus Barbatula (Cypriniformes: Nemacheilidae) from Europe with a neotype designation of B. barbatula (Teleostei: Nemacheilidae)

Journal of Fish Biology, EarlyView.
Abstract Ten species of Barbatula are recognised in Europe, west of the Urals: B. barbatula, B. caucasica, B. hispanica, B. leoparda, B. pironae, B. quignardi, B. sturanyi, B. taurica, B. vardarensis and B. zetensis, with B. caucasica and B. taurica formerly considered subspecies of B. barbatula.

Vestibular modulation of spatial perception [PDF]

, 2013
Vestibular inputs make a key contribution to the own sense of spatial location. While the effects of vestibular stimulation on visuo-spatial processing in neurological patients have been extensively described, the normal contribution of vestibular ...

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

Journal 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

Clinicoepidemiology of benign paroxysmal positional vertigo in Nigerian

Journal of Family Medicine and Primary Care, 2019
Objective: Benign paroxysmal positional vertigo (BPPV) is poorly reported in developing countries. This study aimed at determining the prevalence, aetiology, and comorbid illnesses of benign paroxysmal positional vertigo in our center.

Semicircular canal morphology in Rodentia and its relationship to locomotion

Journal 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

A 3D benign paroxysmal positional vertigo model for study of otolith disease [PDF]

, 1996
ObjectiveTo develop a three-dimensional study tool of the membranous labyrinth in order to study the pathophysiology, diagnostic workup and treatment of benign paroxysmal positional vertigo (BPPV). BPPV is the most common cause of peripheral vertigo. Its

Almost billfish: convergent longirostry, micro‐dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy

Journal of Anatomy, EarlyView.
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.
