The use of otolith morphology to indicate the stock structure of common coral trout (Plectropomus leopardus) on the Great Barrier Reef, Australia [PDF]

, 2006
We investigated the use of otolith morphology to indicate the stock structure of an exploited serranid coral reef fish, Plectropomus leopardus, on the Great Barrier Reef (GBR), Australia.

Stronger effect of temperature on body growth in cool than in warm populations suggests lack of local adaptation

Ecography, EarlyView.
Body size is a key functional trait that has declined in many biological communities, partly due to changes in individual growth rates in response to climate warming. However, our understanding of growth responses in natural populations is limited by relatively short time series without large temperature contrasts and unknown levels of adaptation to ...

Juvenile salmonids traverse coastal meta‐nurseries that connect rivers via the sea

Frontiers in Ecology and the Environment, EarlyView.
Conventionally, juvenile salmonids are thought to migrate unidirectionally from freshwater systems to marine systems and therefore only inhabit natal drainages. Although scattered evidence suggests juveniles can move bidirectionally between freshwater rivers and the ocean, including into non‐natal drainages, such movements have never been documented ...

Auditory chain reaction: Effects of sound pressure and particle motion on auditory structures in fishes.

PLoS ONE, 2020
Despite the diversity in fish auditory structures, it remains elusive how otolith morphology and swim bladder-inner ear (= otophysic) connections affect otolith motion and inner ear stimulation. A recent study visualized sound-induced otolith motion; but

Investigation of otolith asymmetry in Mulloidichthys flavolineatus and Parupeneus forsskali (Perciformes: Mullidae) from Egypt’s Hurghada fishing harbour on the Red Sea

Oceanological and Hydrobiological Studies, 2023
The current study aims to calculate and assess the asymmetry of the two goatfish species, Yellowstripe goatfish Mulloidichthys flavolineatus (Lacepède 1801) and Red Sea goatfish, Parupeneus forsskali (Fourmanoir & Guézé 1976) collected from Hurghada ...

The German Bight (North Sea) is a nursery area for both locally and externally produced sprat juveniles [PDF]

, 2009
To better understand the role of the German Bight (GB) as a nursery area for juvenile North Sea sprat Sprattus sprattus we sought to determine whether the area may receive only locally or also externally produced offspring.

Otopathologic Patterns of Cellular Degeneration in the Peripheral Vestibular Organ Secondary to Head Trauma

The Laryngoscope, EarlyView.
This study examines vestibular degeneration following head trauma, comparing cases with and without fractures. Histopathological analysis of 26 temporal bones showed more severe damage in nonfracture cases, particularly in Scarpa's ganglion cells and vestibular hair cells.

Influence of constant and periodic experimental hypoxic stress on Atlantic croaker otolith chemistry

Aquatic Biology, 2014
The chemical composition of fish otoliths may provide information on the environmental exposure histories of fishes if ‘vital effects’ on element incorporation are minimal.

International Pediatric Otolaryngology Group (IPOG) Consensus on Vestibular Testing in Children

The Laryngoscope, EarlyView.
This study represents the first international consensus on vestibular testing in children. Twenty‐one international experts from nine countries provided guidelines on the recommended minimum test battery necessary to perform a pediatric vestibular assessment.

Otolith Chemistry Reveals Natal Region of Larval Capelin in Coastal Newfoundland, Canada

Frontiers in Marine Science, 2020
Identifying natal origins of animals is key to determining the relative productivity of natal habitats, dispersal of individuals among local populations (i.e., connectivity), and, ultimately, metapopulation dynamics.
