Hydrogen isotopes are unique tools for identifying and understanding biological and
chemical processes. Hydrogen isotope labelling allows for the traceless and direct …

Determining diet is a key prerequisite for understanding species interactions, food web
structure and ecological dynamics. In recent years, there has been considerable …

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 …

Stable isotopes of carbon, nitrogen, and sulfur are used as ecological tracers for a variety of
applications, such as studies of animal migrations, energy sources, and food web pathways …

Stable isotope analysis has emerged as one of the primary means for examining the
structure and dynamics of food webs, and numerous analytical approaches are now …

Compound-specific isotopic analysis of amino acids (CSIA-AA) has emerged in the last
decade as a powerful approach for tracing the origins and fate of nitrogen in ecological and …

All animals face the possibility of limitations in food resources that could ultimately lead to
starvation-induced mortality. The primary goal of this review is to characterize the various …

Stable isotope analysis (SIA) has emerged as a common tool in ecology and has proven
especially useful in the study of animal diet, habitat use, movement, and physiology. SIA has …

The nitrogen isotopic composition (δ15N) of amino acids is potentially useful as an
alternative method for estimating the trophic levels of organisms in food webs. However …

Abstract We open this Special Feature on stable isotopes in mammalian research with a
beginner's guide, an introduction to the novice and a refresher to the well-versed. In this …
