Cranial anatomy of a Late Cretaceous aspidorhynchid fish (Neopterygii: Aspidorhynchiformes) from Alberta, Canada

The Anatomical Record, Volume 309, Issue 11, Page 3123-3136, November 2026.
Abstract Belonostomus longirostrisis was named for an isolated jaw fragment from freshwater Upper Cretaceous (Campanian) sediments of the Dinosaur Park Formation of Alberta, Canada. Following the description of the Albertan species, numerous isolated cranial and postcranial elements have been collected from the Dinosaur Park Formation and assigned to B.

Structure and chemical composition of the otoliths of Cyprinus Carpio [PDF]

, 1973
The need for the study of microfossils such as foraminifera, conodonts, and otoliths as stratigraphic tools has been well established. However, disarticulated parts such as otoliths and conodonts cannot be effectively used unless they can be recognized ...

Color‐Bar Bedsheet: Affordable Assistive Tool for Dix‐Hallpike Test in Primary Care

Journal of General and Family Medicine, Volume 27, Issue 6, November 2026.
ABSTRACT Background Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo encountered in general practice. The definitive diagnosis relies on the Dix‐Hallpike test (DHT), which remains underperformed in primary care due to limited training and unfamiliarity among general practitioners.

Pitfalls in diagnosing and long‐term management of ceroid lipofuscinosis NCL4A in a mixed‐breed dog

Veterinary Record Case Reports, Volume 14, Issue 4, November 2026.
Abstract An 8‐year‐old, spayed, female, mixed‐breed dog was presented with a 9‐month history of occasionally stumbling on walks, having difficulty navigating stairs and jumping into the car. A prior computed tomography scan of the head revealed mild leptomeningeal enhancement and suggested meningoencephalitis.

Nocturnal Hypoxemia Burden Correlates With Vestibular Dysfunction in Obstructive Sleep Apnea

Clinical Otolaryngology, Volume 51, Issue 6, Page 894-901, November 2026.
ABSTRACT Introduction Obstructive sleep apnea (OSA) is a potential contributor to vestibular dysfunction, though specific correlating parameters remain unclear. This study aimed to determine whether hypoxemia severity indices correlate quantitatively with caloric slow‐phase eye velocity (SPV), a marker of vestibular function. Methods In a retrospective

Coexisting in the Surf Zone: Age and Feeding Habits of the Spotted Seabass (Dicentrarchus punctatus) and European Seabass (Dicentrarchus labrax) on the Gulf of Cádiz Beaches (Southwest Iberian Peninsula)

Fishes
Various commercial fish species utilize different coastal habitats as nurseries in their juvenile stages, with surf zones being particularly crucial due to the protection and abundant food resources they offer.

Validation of annulus formation in white perch otoliths, including characteristics of an invasive population

Journal of Freshwater Ecology, 2017
Accurately ageing fish is essential for fisheries managers when calculating population dynamics for a particular species. Despite being a popular sport fish in its native range with a large expanding non-native range, otoliths of white perch Morone ...

Inferring the Number of Spawning Events From Young‐of‐the‐Year Genomic Samples and Otolith‐Derived Birth Dates: A Richness‐Estimator Perspective

Fish and Fisheries, Volume 27, Issue 6, Page 1283-1289, November 2026.
ABSTRACT Estimating the number of spawning events per female is key to understanding reproductive output in batch‐spawning species, yet direct observation is often infeasible in the wild. Recent advances in genetic kinship inference enable the identification of maternal half siblings from young‐of‐the‐year genomic samples, while otolith‐based age ...
