Assessments of temporal variation in diets are important for our understanding of the
ecology of many vertebrates. Ratios of naturally occurring stable isotopes in animal tissues …

Stable isotopes are being increasingly used in wildlife forensics as means of determining
the origin and movement of animals. The heavy isotope content of precipitated water and …

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 …

The carbon isotope fractionation between tooth enamel bioapatite, breath CO2, and diet was
measured for voles, rabbits, pigs, and cattle on controlled diets. The measured fractionation …

Stable isotopes are increasingly used in animal ecology, but little attention has been paid to
the underlying physiological processes accounting for changes in 15N/14N and 13C/12C …

We used stable isotopes of C in breath, blood, feces and feathers to identify intra-individual
changes in diet and the timescale of diet changes in free-living songbirds at a stopover site …

The structural proteins that comprise∼ 90% of animal hair have the potential to record
environmentally and physiologically determined variation in δ2H and δ18O values of body …

On présume que les signatures d'isotopes stables dans les tissus animaux reflètent le
réseau alimentaire local. Cependant, cette supposition peut être compliquée par le …

Mammalian teeth are invaluable archives of ancient seasonality because they record along
their growth axes an isotopic record of temporal change in environment, plant diet, and …

Since the mid-1970s, stable carbon isotopes have been used extensively to address diverse
questions related to estuarine carbon cycling. Initially, the isotopic approach was used to …
