Chemical analysis of calcified structures continues to flourish, as analytical and
technological advances enable researchers to tap into trace elements and isotopes taken up …

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 …

The nitrogen isotopes (δ 15 N) in the organic fraction of accretionary hard part structures,
such as fish otoliths, may provide life histories of dietary change. We performed controlled …

For marine fishes of commercial interest, defining how individuals vary in certain attributes,
through ontogeny, and across space and time, can help expose the structure of harvested …

Delineating the stock structure of highly-mobile, wide-ranging fishes subject to exploitation is
a challenging task, yet one that is fundamental to optimal fisheries management. A case in …

Context Although stable carbon (δ13C) and nitrogen (δ15N) isotopes are widely used to
study feeding ecology, the use of these isotopes in otolith organic matter to assess the diet of …

The combined use of otolith chemistry and tissue isotopes has the potential to reveal
movements, habitat associations and food web interactions at a variety of spatial and …

This study investigates the food web structure of the **nlicheng Reservoir, a drinking water
source of critical importance in Changchun, China, by employing stable isotope analysis …

Reconstruction of the trophic position of a fish can be performed by analysing stable
nitrogen and carbon isotopes in otolith protein. However, ambient temperature may affect …

Rationale Otoliths are usually used to estimate the age of fish and the chemical composition
such as nitrogen stable isotope ratios (δ15N values) may record environmental information …
