Abstract

Stable isotope analysis has proved to be an extremely useful tool in elucidating many ecological problems, with stable isotope ecology comprising the theme of a series of international conferences (http://www.isoecol.org). Stable isotopes can be used as biological tracers in the following ways: (1) to identify sources, for instance in determining the identity of basal carbon in a food web; (2) to distinguish sources, for example to determine whether a breeding animal is using local resources or its own reserves, or when an animal migrates/disperses from one location to another and (3) to quantify relative inputs in a system, for example determining the proportions of different prey items to a consumer's diet. When utilised carefully, stable isotope analysis provides some advantages over conventional methods and an additional device for the ecologist.
