Stable Isotopes and Planktonic Trophic Structure in Arctic Lakes

Actual food—web structure or function is difficult to determine based on visual observation, gut analyses, or the feeding interactions expected from a given list of species. We ...

THE STABLE NITROGEN ISOTOPE RATIO AS A MARKER OF FOOD-WEB INTERACTIONS AND FISH MIGRATION

We used stable nitrogen isotopes to describe the pelagic food-web structure of three coastal Baltic Sea areas, each of which was sampled twice. Two of the areas were influenced ...

Food web structure on Georges Bank from stable C, N, and S isotopic compositions

A combination of stable isotopic measurements was used to study food web structure of Georges Bank, an important northwestern Atlantic fishing ground. Particulate, invertebrate,...
