Natural abundances of the rare stable isotope of nitrogen, 15 N, are now being used widely
in research on N cycling in organisms and ecosystems. 15 N natural abundances are used …

Stable isotope mixing models are increasingly used to quantify consumer diets, but may be
misused and misinterpreted. We address major challenges to their effective application …

About 10 years ago, reviews of the use of stable isotopes in animal ecology predicted
explosive growth in this field and called for laboratory experiments to provide a mechanistic …

Strontium isotope analysis of bone and tooth enamel from prehistoric human skeletons is an
