Effects of aging on otolith morphology and functions in mice [PDF]

Frontiers in Neuroscience
BackgroundIncreased fall risk caused by vestibular system impairment is a significant problem associated with aging. A vestibule is composed of linear acceleration-sensing otoliths and rotation-sensing semicircular canals.

Investigating otolith mass asymmetry in six benthic and pelagic fish species (Actinopterygii) from the Gulf of Tunis [PDF]

Acta Ichthyologica et Piscatoria, 2021
Otolith mass asymmetry can significantly affect the vestibular system functionalities; usually, the X values of mass asymmetry vary between −0.2 and + 0.2 (−0.2 < X < + 0.2). These values can change during a fish life and therefore they are

The Superiority of the Otolith System [PDF]

Audiology and Neurotology, 2020
<b><i>Background:</i></b> The peripheral vestibular end organ is considered to consist of semi-circular canals (SCC) for detection of angular accelerations and the otoliths for detection of linear accelerations. However, otoliths being phylogenetically the oldest part of the vestibular sensory organs are involved in detection of

Comparative Otolith Morphology of Two Morphs of Schizopygopsis thermalis Herzenstein 1891 (Pisces, Cyprinidae) in a Headwater Lake on the Qinghai-Tibet Plateau

Fishes, 2022
Teleost otoliths provide a pivotal medium for studying changes in population structure and population dynamics of fish. Understanding the otolith-fish size relationship and intraspecies variation in otolith morphology is essential for the accurate ...

Relationship between Body and Otolith Morphological Characteristics of Sabre Squirrelfish (Sargocentron spiniferum) from the Southern Red Sea: Difference between Right and Left Otoliths

Oceans, 2021
Otolith morphology analysis is one of the main tools used for fish or fish stock identification. Moreover, otolith shape can also be used in animal dietary studies (stomach content) for the identification of prey fishes and their size according to the ...

Within-otolith variability in chemical fingerprints: implications for sampling designs and possible environmental interpretation. [PDF]

PLoS ONE, 2014
Largely used as a natural biological tag in studies of dispersal/connectivity of fish, otolith elemental fingerprinting is usually analyzed by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS).

AGE, GROWTH AND OTOLITH BIOMETRY-BODY LENGTH RELATIONSHIPS OF RED BANDFISH (Cepola macrophthalma L., 1758) IN THE SEA OF MARMARA, TURKEY

Trakya University Journal of Natural Sciences, 2020
The age, growth, and the otolith biometry-total length relationships of Cepola macrophthalma (Linnaeus, 1758) were investigated. The individuals were caught with beam trawl in the Sea of Marmara from March 2012 to June 2014.
