Diet information of organisms was traditionally acquired by the use of lethal techniques (gut
content or muscle δ13C and δ15N isotopic ratios). An increase in the number of isotopic …

The aim of this study was to analyze the isotopic composition in muscle of striped weakfish
Cynoscion guatucupa from Southwest Atlantic Ocean in order to evaluate a possible …

Rationale Stable isotope analysis (SIA) has revolutionised ecological studies over the past
thirty years. One of the major fields where SIA is applied in the marine environment is related …

White muscle has been traditionally used in determining δ 13 C and δ 15 N signatures in
fish but ethics and the current conservation status of many species mean the application of …

Stable isotope analysis of fishes is often performed using muscle or organ tissues that
require sacrificing animals. Non‐lethal sampling provides an alternative for evaluating …

Application of stable isotope data to trophic studies requires understanding of factors
influencing the isotopic discrimination factor (Δ) between consumers and their prey …

Rationale Dorsal white muscle is the standard tissue analysed in fish trophic studies using
stable isotope analyses. As muscle is usually collected destructively, fin tissues and scales …

We collected flying fish (Exocoetus volitans) from the South China Sea to determine whether
fish scale isotope values correlate with those from muscle, and discuss relevant eco …

In the present study, Xyrichtys novacula (Labridae) were sampled at five locations around
the islands of Ibiza and Formentera (western Mediterranean Sea). Isotopic signatures of …

Carbon (δ 13 C) and nitrogen (δ 15 N) stable isotope analyses are used in marine ecology
to study trophic relationships and migrations of species since they reflect dietary sources …
