Detection of breastfeeding and weaning in modern human infants with carbon and nitrogen stable isotope ratios.
Carbon ((13)C/(12)C) and nitrogen ((15)N/(14)N) stable isotope ratios were longitudinally measured in fingernail and hair samples from mother-infant pairs where infants were exclusively breastfed (nExpand

Stable carbon and nitrogen isotope values of bone and teeth reflect weaning age at the Medieval Wharram Percy site, Yorkshire, UK.
We report on the measurements of carbon and nitrogen stable isotopes of both bone and teeth from a single site and population (Medieval Wharram Percy), undertaken to explore variations due to weaningExpand

Genomic evidence for the Pleistocene and recent population history of Native Americans
Genetic history of Native Americans Several theories have been put forth as to the origin and timing of when Native American ancestors entered the Americas. To clarify this controversy, Raghavan etExpand

Nitrogen balance and δ15N: why you're not what you eat during pregnancy
Carbon (13C/12C) and nitrogen (15N/14N) stable isotope ratios were longitudinally measured in human hair that reflected the period from pre-conception to delivery in 10 pregnant women. There was noExpand

Stable carbon and nitrogen isotope variations in tooth dentine serial sections from Wharram Percy.
Here we report δ13C and δ15N measurements of serial sections of human deciduous and permanent tooth dentine from archaeological samples taken from the medieval village site of Wharram Percy,Expand

Nitrogen balance and δ15N: why you're not what you eat during nutritional stress
While past experiments on animals, birds, fish, and insects have shown changes in stable isotope ratios due to nutritional stress, there has been little research on this topic in humans. To addressExpand

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

Isotopic evidence for breastfeeding and possible adult dietary differences from Late/Sub-Roman Britain.
Historical documents indicate that breastfeeding and weaning practices have fluctuated in England through history. In order to obtain evidence for general breastfeeding patterns in Late/Sub-RomanExpand

Stable isotope palaeodietary study of humans and fauna from the multi-period (Iron Age, Viking and Late Medieval) site of Newark Bay, Orkney
We report here on stable carbon and nitrogen isotope measurements of human and faunal bone collagen from the Iron Age, Viking Age, and Late Medieval site of Newark Bay, Orkney, Scotland. We found aExpand

Exploring the contribution and significance of animal protein in the diet of bonobos by stable isotope ratio analysis of hair
In primates, age, sex, and social status can strongly influence access to food resources. In Pan, these criteria are assumed to influence access to vertebrate meat. However, the significance of meatExpand
