Analysis of stable carbon and nitrogen isotopes from soft or mineralized tissues is a direct
and widely‐used technique for modeling diets. In addition to its continued role in paleodiet …

ABSTRACT 1 Stable isotope analysis (SIA) has the potential to become a widespread tool in
mammalian ecology, because of its power in resolving the ecological and behavioural …

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 …

Measurements of δ 15 N of consumers are usually higher than those of their diet. This
general pattern is widely used to make inferences about trophic relationships in ecological …

The “trophic level enrichment” between diet and body results in an overall increase in
nitrogen isotopic values as the food chain is ascended. Quantifying the diet–body Δ15N …

The stable isotope composition of animal tissues can provide intrinsic tags to study the
foraging and migratory ecology of predators in the open ocean. Chapter 13 (this volume) …

Since the discovery of isotopes and the development of precise instrumentation capable of
measuring small differences in isotope abundances, there has been an interest in …

While past experiments on animals, birds, fish, and insects have shown changes in stable
isotope ratios due to nutritional stress, there has been little research on this topic in humans …

Isotope turnover in muscle of ectotherms depends primarily on growth rather than on
metabolic replacement. Ectotherms, such as fish, have a discontinuous pattern of growth …

Using measurements of naturally occurring stable isotopes to reconstruct diets or source of
feeding requires quantifying isotopic discrimination factors or the relationships between …
