Alkali Element Uptake in Otoliths: A Link Between the Environment and Otolith Microchemistry
Environmental Science & Technology, 2008Otoliths taken from fish in the vicinity of rare element pegmatites in eastern Manitoba, Canada, were analyzed using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) and found to contain lithium, sodium, rubidium, cesium, and strontium at levels ranging from a few ppm to a few 10s of ppm.

Morphology and microchemistry of the otoliths of the inner ear of anuran larvae
Hearing Research, 2016To navigate in space most vertebrates need precise positional cues provided by a variety of sensors, including structures in the inner ear, which are exquisitely sensitive to gravity and linear acceleration. Although these structures have been described in many vertebrates, no information is available for anuran larvae.

Environmental sensitivity of fish Otolith Microchemistry
Australian Journal of Marine and Freshwater Research, 1992A considerable aggregate of life-history, environmental and physiological information is incorporated within fish otoliths. This information may be discerned when appropriate analytical methods, based on an understanding of the mechanisms underlying changes in the structure and chemistry of otoliths, are utilized. Deposition of otolith carbonate may be

Taxonomic and geographic influences on fish otolith microchemistry
Fish and Fisheries, 2012AbstractFish otoliths are comprised primarily of CaCO3 and grow throughout an individual's lifetime. The chemical composition of otoliths is often a distinctive characteristic of the populations that live in discrete areas, and as a result, it has been used for population classification studies, supporting ecological and fisheries research.

Otolith microchemistry of tropical diadromous fishes: spatial and migratory dynamics
Journal of Fish Biology, 2014Otolith microchemistry was applied to quantify migratory variation and the proportion of native Caribbean stream fishes that undergo full or partial marine migration. Strontium and barium water chemistry in four Puerto Rico, U.S.A., rivers was clearly related to a salinity gradient; however, variation in water barium, and thus fish otoliths, was also ...

Bayesian hierarchical mixture models for otolith microchemistry analysis
Environmental and Ecological Statistics, 2012The field of fisheries research commonly uses classical statistical classification methods to estimate the proportion of fish that return to natal spawning grounds to spawn. With the advent of otolith microchemical analysis, researchers are able to extract information from fish ear stones (otoliths) about the chemical composition of water in which fish

Morphology and microchemistry of abnormal otoliths in the ayu, Plecoglossus altivelis
Environmental Biology of Fishes, 2007The sagittal otolith morphology and microchemistry of reared juvenile ayu, Plecoglossus altivelis, were examined to describe the occurrence and microchemical characteristics of the abnormal otoliths in this species. Juvenile ayu (N = 31) were collected in June 2004 at three different locations, Wakayama, Kumamoto, and Biwa Lake in Japan, where they ...

Otolith microchemistry: Insights into bioavailable pollutants in a man-made, urban inlet
Marine Pollution Bulletin, 2017Black bream (Acanthopagrus butcheri) were collected from an artificial inlet, Claisebrook Cove, Western Australia. Claisebrook Cove is adjacent to an historic contaminated site that was remediated during the 1990s. It was later identified as a priority area due to elevated levels of sediment contaminants including Zn, Cu, and Pb.

Exploring the potential of otolith microchemistry to enhance diet analysis in pinnipeds
Marine Biology, 2009Increasing the scope and accuracy of information about pinniped diets obtainable from non-invasive techniques is increasingly important, particularly in cases where pinniped species are threatened or endangered. This study is the first to explore the potential for using elemental analysis of the otoliths found in scat to enhance the information ...

Ecological Applications, 2011
Reliable assessment of fish origin is of critical importance for exploited species, since nursery areas must be identified and protected to maintain recruitment to the adult stock. During the last two decades, otolith chemical signatures (or "fingerprints") have been increasingly used as tools to discriminate between coastal habitats.
