Strontium isotope analysis of archaeological skeletons has provided useful and exciting
results in archaeology in the last 20 years, particularly by characterizing past human …

Between fifty and ten thousand years ago, most large mammals became extinct everywhere
except Africa. Slow-breeding animals also were hard hit, regardless of size. This unusual …

Differential fractionation of stable isotopes of carbon during photosynthesis causes C4
plants and C3 plants to have distinct carbon-isotope signatures. In addition, marine C3 …

The isotope enrichment ɛ* of 13 C between tooth enamel of large ruminant mammals and
their diet is 14.1±0.5‰. This value was obtained by analyzing both the dental enamel of a …

For decades, plant ecologists have used naturally occurring stable isotope ratios to
disentangle ecological and physiological processes. The methodology can also become a …

The second edition of The Biomarker Guide is a fully updated and expanded version of this
essential reference. Now in two volumes, it provides a comprehensive account of the role …

Chemical, biological, and physical processes lead to distinctive “isotopic signatures” in
biological materials that allow tracing of the origins of organic substances. Isotopic variation …

▪ Abstract Vertebrate fossils and continental sediments provide a rich record of variations in
the isotopic composition of surface environments. To interpret these records, a greater …

Naturally occurring variations in the stable isotope composition of fossil vertebrates have
been studied since the late 1970s. Isotopic data from vertebrate fossils are sometimes used …

Rats were raised on a variety of isotopically controlled diets comprising 20% C3, C4 or
marine protein and C3 and/or C4 non-protein or energy (ie sucrose, starch and oil) …
