The use of stable carbon isotopes as a means of studying energy flow is increasing in
ecology and paleoecology. However, secondary fractionation and turnover of stable …

Studies of birds that use stable isotopes as dietary tracers require estimates of how quickly
stable isotopes in tissues are replaced by isotopes derived from the diet. However, isotopic …

In two laboratory experiments using tilapia (Oreochromis niloticus) and common carp
(Cyprinus carpio), we investigated the effect of lipid content in the fish carcass on the stable …

Understanding rates of isotopic incorporation and discrimination factors between tissues
and diet is an important focus of ecologists seeking to use stable isotopes to track temporal …

Differential fractionation of stable isotopes of carbon during photosynthesis causes C4
plants and C3 plants to have distinct carbon-isotope signatures. In addition, marine C3 …

As part of a larger experiment, 31 young bulls, divided into three groups, were given different
diets containing either C3 plants or a combination of C3 and C4 plant‐based feeds in three …

Increased use of stable isotope analysis to examine food-web dynamics, migration, transfer
of nutrients, and behavior will likely result in expansion of stable isotope studies …

Stable isotopes have proven to be a useful tool for deciphering food webs, examining
migration patterns and determining nutrient resource allocation. In order to increase the …

Stable isotope analyses are often used to calculate relative contributions of multiple food
sources in an animal's diet. One prerequisite for a precise calculation is the determination of …

Studies using stable-isotope analysis to infer diet require a knowledge of how stable-isotope
ratios in consumer tissues are related to dietary values. We determined δ 13C and δ 15N …
