Influence of Diet On the Distribtion of Nitrogen Isotopes in Animals
Michael J. DeNiro,Samuel Epstein +1 more
TL;DR: In this article, the influence of diet on the distribution of nitrogen isotopes in animals was investigated by analyzing animals grown in the laboratory on diets of constant nitrogen isotopic composition and found that the variability of the relationship between the δ^(15)N values of animals and their diets is greater for different individuals raised on the same diet than for the same species raised on different diets.

Strontium isotopes and mobility of a Columbian mammoth (Mammuthus columbi) population, Laguna de las Cruces, San Luis Potosí, México
Víctor Adrián Pérez-Crespo,Peter Schaaf,Gabriela Solís-Pichardo,Joaquín Arroyo-Cabrales,Luis M. Alva-Valdivia,José Ramón Torres-Hernández +5 more
TL;DR: This paper used strontium isotopic ratios of dental enamel from molars to reconstruct the migration context for three individuals of a Columbian mammoth population (Mammuthus columbi ) around Laguna de las Cruces, San Luis Potosi, central Mexico.

Influence of diet on the distribution of nitrogen isotopes in animals
Michael J. DeNiro,Samuel Epstein +1 more
TL;DR: In this article, the influence of diet on the distribution of nitrogen isotopes in animals was investigated by analyzing animals grown in the laboratory on diets of constant nitrogen isotopic composition and found that the variability of the relationship between the δ(15)N values of animals and their diets is greater for different individuals raised on the same diet than for the same species raised on different diets.

Carbon isotope fractionation in plants
TL;DR: In this paper, the authors present a mathematical model to predict the overall isotope discrimination in terms of diffusion, interconversion, incorporation, and respiration in C 3, C 4 and crassulacean acid metabolism (CAM) photosynthetic pathways.

Global vegetation change through the Miocene/Pliocene boundary

TL;DR: For example, this paper found that between 8 and 6 million years ago, there was a global increase in the biomass of plants using C4 photosynthesis as indicated by changes in the carbon isotope ratios of fossil tooth enamel in Asia, Africa, North America and South America.
