Sulphur isotope analysis of archaeological materials provides information on past
ecosystems, palaeo-diets, migration and mobility. This review covers the geochemical …

Diet is a leading modifiable risk factor for chronic disease, but it remains difficult to measure
accurately due to the error and bias inherent in self-reported methods of diet assessment …

The “trophic level enrichment” between diet and body results in an overall increase in
nitrogen isotopic values as the food chain is ascended. Quantifying the diet–body Δ15N …

Anthropogenic and natural sources contribute to chemical mixtures in air, water, and soil,
posing potential risks to the environment and human health. To understand the interplay …

Background Darwin's finches are a clade of 19 species of passerine birds native to the
Galápagos Islands, whose biogeography, specialized beak morphologies, and dietary …

Stable sulphur isotope ratios (34S/32S) in animal tissues have been suggested as a tracer
of coastal residency of terrestrial animals, but data are lacking that quantify the inland range …

Stable carbon and nitrogen isotope analyses are widely used to infer diet and mobility in
ancient and modern human populations, potentially providing a means to situate humans in …

Three cleaning techniques that remove external contamination of human hair are assessed
to investigate the potential use of Sr and Pb isotope composition of hair for human …

Unidentified human remains have historically been investigated nationally by law
enforcement authorities. However, this approach is outdated in a globalized world with rapid …

Many physical and chemical processes in living systems are accompanied by isotope
fractionation on H, C, N, O and S. Although kinetic or thermodynamic isotope effects are …
