Carbon isotope fractionation between diet, breath CO2, and bioapatite in different mammals
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 (expressed asExpand

Nitrogen isotopes in mammalian herbivores: hair δ15N values from a controlled feeding study
Nitrogen isotope analysis is a common technique for investigating dietary behaviour in modern and archaeological populations. One of its primary uses is to provide trophic level information. ThisExpand

An experimental study of carbon-isotope fractionation between diet, hair, and feces of mammalian herbivores
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 inExpand

Abstract Although bovids have been studied for decades, debate still exists about their diets. To address this problem, we examined bovid dietary ecology through analysis of stable carbon isotopes.Expand

An experimental study of nitrogen flux in llamas: is 14N preferentially excreted?
Nitrogen isotope analysis is now commonly used to investigate the diets, and to a lesser extent, the environments of ancient populations. These studies assume that mammals are predictably enriched inExpand

Sulphur isotopes in palaeodietary studies: a review and results from a controlled feeding experiment
Recent advances in mass spectrometry now allow relatively routine measurements of sulphur isotopes (δ 34 S) in small samples (>10 mg) of tissue from archaeological human, plant, and faunal samples. δExpand

Turnover of stable carbon isotopes in the muscle, liver, and breath CO2 of alpacas (Lama pacos).
Stable carbon isotope analysis of animal liver and muscle has become a widespread tool for investigating dietary ecology. Nonetheless, stable carbon isotope turnover of these tissues has not beenExpand

Digestion and passage rates of grass hays by llamas, alpacas, goats, rabbits, and horses
Many studies have suggested that South American camelids (SAC) have greater digestive efficiency than pecoran ruminants, but others have found no difference. In an effort to provide new data on thisExpand

Inverse methods for estimating primary input signals from time-averaged isotope profiles
Abstract 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 animalExpand

Short-term diet changes revealed using stable carbon isotopes in horse tail-hair
Summary 1. We demonstrate the potential of extracting high-resolution dietary information from stable carbon isotopes ( δ 13 C) in horse tail-hair, in response to short-term changes in diet inExpand
