Otolith chemistry
An otolith (Greek: ὠτο-, ōto- ear + λῐ́θος, líthos, a stone), also called statoconium or otoconium or statolith, is a calcium carbonate structure in the saccule or utricle of the inner ear, specifically in the vestibular system of vertebrates. The saccule and utricle, in turn, together make the otolith organs. These organs are what allows an organism, including humans, to perceive linear acceleration, both hori… WebJan 1, 2024 · (a) Annual publications of otolith chemistry papers from 1967 to 2024 as indexed in ISI Web of Science (search terms: otolith AND chem* OR microchem* OR …

WebOtolith 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 dependent on … WebJul 1, 2024 · A selection of elements was used to illustrate the variation in otolith chemistry throughout the life history of C. myriaster (Fig. 4). Sr: Ca ratio dropped rapidly from the otolith core, and tended to be stable at the lowest level between the end of metamorphosis and the first ring, and then increased to a relatively stable level (Fig. 4 A).
