The evolving story of catadromy in the European eel (Anguilla anguilla)
Anguillid eels were once considered to be the classic example of catadromy. However,
alternative life cycles have been reported, including skipping the freshwater phase and …

Diet‐tissue discrimination factors and turnover of carbon and nitrogen stable isotopes in tissues of an adult predatory coral reef fish, Plectropomus leopardus
Rationale Stable isotope ratios (δ13C and δ15N values) provide a unique perspective into
the ecology of animals because the isotope ratio values of consumers reflect the values in …

Small tails tell tall tales–intra-individual variation in the stable isotope values of fish fin
Background Fish fin is a widely used, non-lethal sample material in studies using stable
isotopes to assess the ecology of fishes. However, fish fin is composed of two distinct tissues …

Individual isotopic specializations predict subsequent inter‐individual variation in movement in a freshwater fish
Despite many similarities and intuitive links between individual dietary specialization and
behavioral inter‐individual variation, these phenomena have been studied in isolation, and …
