Title Experimental study of carbon-isotope fractionation between diet, hair, and feces of mammalian herbivores
Date 2003
Description The carbon-isotope composition of hair and feces offers a glimpse into the diets of mammalian herbivores. It is particularly useful for determining the relative consumption of browse and graze in tropical environments, as these foods have strongly divergent carbon-isotope compositions. Fecal ?13C values reflect the last few days consumption, whereas hair provides longer term dietary information. Previous studies have shown, however, that some fractionation occurs between dietary ?13C values and those of hair and feces.
