Nitrogen and carbon stable isotope variation in northeast Atlantic fishes and squids
Nitrogen and carbon stable isotope data are frequently used to describe the origins and transformations of organic matter. Nitrogen stable isotopes (δ 15 N) in tissue are used to estimate species' trophic levels, the extent of omnivory, food chain length, and community-wide relationships betwee...

Nitrogen and carbon stable isotope data are frequently used to describe the origins and transformations of organic matter. Nitrogen stable isotopes (δ 15 N) in tissue are used to estimate species' trophic levels, the extent of omnivory, food chain length, and community-wide relationships between body size and trophic level; the latter leading to estimates of predator–prey mass ratios for parameterization, calibration, and validation of food web models. Carbon stable isotopes (δ 13 C) are used to identify pathways linking producers and consumers and for studies of migration and movement. Collectively, δ 15 N and δ 13 C, often with other stable isotopes such as δ 34 S, may be used to define the contribution of different producers and pathways to consumer production, to assess the trophic impacts of invasive species and habitat modification, and to predict past habitat use, movements, and migrations. Stable isotope data often complement dietary data (e.g., from stomach contents) in food web studies, because stable isotope composition is indicative of assimilated diet over months to years, depending on species, size, environment, and tissue type. There are relatively few large-scale compilations of δ 15 N and δ 13 C data for marine species from offshore habitats, but such data facilitate comparative analysis and research into food web structure and function.
