Carbon stable isotope signatures can effectively trace food sources, elucidate trophic
interactions, and presumably reflect food web structure. The present study conducted a diet …

Analysis of stable carbon isotopes is a valuable tool for studies of diet, habitat use and
migration. However, significant variability in the degree of trophic fractionation (Δ13CC‐D) …

Societal interest in food safety, animal welfare, and environmental quality attributes of food
production is increasing, creating a need for reliable indicators of such factors. Here we test …

Introduction earbon stable isotope analysis is being used increasingly by ecologists
studying energy flow in both terrestrial and aquatic ecosystems (see reviews by PETERSON …

Stable isotope analysis of consumer tissues document patterns of resource use because
data are linearly related to isotope compositions of their source (s)(ie, food, water, etc.) …

Compound‐specific stable isotope analysis (CSIA) of amino acids (AA) has rapidly become
a powerful tool in studies of food web architecture, resource use, and biogeochemical …

Stable isotope analysis of carbon and nitrogen has revolutionized anthropology's approach
and understanding of the evolution of human diet. A baseline comparison across extant …

Stable isotope analysis can be used to document dietary changes within the lifetimes of
individuals and may prove useful for investigating fallback food consumption in modern …

Rationale Stable isotopes are a prominent tool in animal ecology where data is obtained
from analyzing animal tissues, which are typically stored prior to analysis. However, the …

Studies of stable isotope signatures can reveal and quantify trophic carbon transfer between
organisms. However, preservation of the samples before analysis cannot always be …
