Variation in discrimination factors (Δ15N and Δ13C): the effect of diet isotopic values and applications for diet reconstruction

S Caut, E Angulo, F Courchamp - Journal of Applied Ecology, 2009 - Wiley Online Library
Summary 1 The use of stable isotopic techniques to study animal diets and trophic levels

Uncertainty in source partitioning using stable isotopes

DL Phillips, JW Gregg - Oecologia, 2001 - Springer
Stable isotope analyses are often used to quantify the contribution of multiple sources to a
mixture, such as proportions of food sources in an animal's diet, or C 3 and C 4 plant inputs …

Incorporating concentration dependence in stable isotope mixing models

DL Phillips, PL Koch - Oecologia, 2002 - Springer
Stable isotopes are often used as natural labels to quantify the contributions of multiple
sources to a mixture. For example, C and N isotopic signatures can be used to determine the …

Converting isotope values to diet composition: the use of mixing models

DL Phillips - Journal of Mammalogy, 2012 - academic.oup.com
A common use of stable isotope analysis in mammalogy is to make inferences about diet
from isotope values (typically δ13C and δ15N) measured in tissues and food sources of a …

The effect of dietary protein quality on nitrogen isotope discrimination in mammals and birds

CT Robbins, LA Felicetti, M Sponheimer - Oecologia, 2005 - Springer
We tested the competing hypotheses that (1) nitrogen discrimination in mammals and birds
increases with dietary nitrogen concentration or decreasing C: N ratios and, therefore …

Applications of stable isotope techniques to the ecology of mammals

K Crawford, RA Mcdonald, S Bearhop - Mammal Review, 2008 - Wiley Online Library
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 …
