1. Ten years ago Gannes et al (1997, Stable isotopes in animal ecology: assumptions,
caveats, and a call for laboratory experiments. Ecology, 78, 1271-1276, 1998) identified four …

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 …

Ecologists conduct isotopic incorporation experiments to determine the residence time of
various stable isotopes in animal tissues. These experiments permit determining the time …

The analysis of natural stable isotope ratios has created a methodological upheaval in
animal ecology. Because the distribution of stable isotopes in organisms follows reliable …

We propose a new model that uses an organism's change in mass to estimate isotope
incorporation rates. Our model is a re‐parameterization of a widely used one‐compartment …

Stable isotope analysis has become an important tool in studies of trophic food webs and
animal feeding patterns. When animals undergo rapid dietary shifts due to migration …

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 …

The interpretation of isotopic data gathered in the field often demands knowing the rate at
which isotopes are incorporated into different tissues and species, and the discrimination …

Animals usually show a δ15N value that is slightly higher than that of their food. The value of
this enrichment appears to be fairly constant among species (approximately 3‰). This …

For decades, plant ecologists have used naturally occurring stable isotope ratios to
disentangle ecological and physiological processes. The methodology can also become a …
