FishesOwing to the asynchronous deposition of trace elements between paired left and right otoliths within individual fish, researchers must consciously and uniformly use only single otoliths (especially the left one) for microchemical studies.

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean
Remote Sensing in Ecology and Conservation, EarlyView.The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

To glue or not to glue? Reassembling broken otoliths for population discrimination
, 2014 Twenty-five Atlantic cod Gadus morhua otoliths were examined using eight shape measurements along with Fourier analysis of their outlines to test whether discrimination using otolith shape is affected by gluing broken otoliths. Small differences in seven

Zoodiversity, 2021 This study aims to assess the round goby Neogobius melanostomus stocks discriminability based on the shape of its otoliths. Recent otolith-shape-based species and stock discrimination studies have been using otoliths’ contours in sagittal plane and we ...

Subjective Visual Vertical Can be an Effective Tool to Evaluate Vestibular Function of Stapedotomy
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Objective To investigate if the subjective visual vertical/horizontal (SVV/SVH) can be used to evaluate the otolith organ of otosclerosis and stapedotomy. Design A total of 19 patients who were diagnosed with otosclerosis and underwent surgical treatment in our hospital were collected.

Peeling the Otolith of Fish: Optimal Parameterization for Micro-CT Scanning
Frontiers in Marine Science, 2019 In this paper, we aim to provide optimal parameters for micro-computed tomography scans of fish otoliths. We tested fifteen different combinations to sagittae. The images were scaled to Hounsfield units, and segmented in two distinct volumes-of-interest (

Unveiling Otolith Mystery: Contemporary Testing Approaches and Their Clinical Significance
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Objective Otolith is a critical component of the peripheral vestibular system responsible for detecting linear acceleration. Dysfunction of the otolith organs can lead to vertigo, balance disturbances, and gaze instability. By elucidating the physiological foundations and evaluating both current and emerging methods for assessing otolith ...

Reconstructing reef fish communities using fish otoliths in coral reef sediments.
PLoS ONE, 2019 Little is known about long-term changes in coral reef fish communities. Here we present a new technique that leverages fish otoliths in reef sediments to reconstruct coral reef fish communities. We found over 5,400 otoliths in 169 modern and mid-Holocene

Phylogenetic and ecological duality in the otoliths of Sciaenidae
Cladistics, EarlyView.Abstract Teleost fishes have evolved taxon‐specific otoliths that vary greatly in size and shape and are primarily involved in hearing and balance. This study identifies the main drivers of otolith shape disparity in Sciaenidae, a clade of sound‐producing bony fishes, using three‐dimensional geometric morphometrics (3DGM).
