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 …

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 …

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 development of the isotopic niche, an n-dimensional hypervolume (with n being the
number of isotopes) occupied by a population in delta space, has revolutionized the study of …

In the past 20 years the use of stable isotope analysis has become increasingly common in
ecological studies. In fact, in some instances these techniques have yielded remarkable …

Apex predators are often assumed to be dietary generalists and, by feeding on prey from
multiple basal nutrient sources, serve to couple discrete food webs. But there is increasing …

Stable‐isotope analysis (SIA) can act as a powerful ecological tracer with which to examine
diet, trophic position and movement, as well as more complex questions pertaining to …

Identifying the composition of avian diets is a critical step in characterizing the roles of birds
within ecosystems. However, because birds are a diverse taxonomic group with equally …

The stable isotopes of carbon (12C, 13C) and nitrogen (14N, 15N) represent powerful tools
in food web ecology, providing a wide range of dietary information in animal consumers …

Ignorance of the location or inaccessible locations of lifestages can impede the study and
management of species. We used stable isotopes of carbon and nitrogen to identify the …
