Abstract
Stable isotope geochemistry 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: (i) to identify sources, for instance in determining the identity of basal carbon in a food web; (ii) to distinguish sources, for example to determine whether a breeding animal is using local resources or itsownreserves; (iii) to quantify relative inputs in a system, for example determining the proportions of different prey items to a consumer’s diet. When utilized carefully, stable isotope geochemistry provides some advantages over conventional methods, and provides an additional device for the ecologist. The following article provides a short reference for ecologists considering the inclusion of stable isotope analysis as part of their methodology.
