SYSTEMATICS: OXYGEN AND HYDROGEN IN ANIMALS

REQUIRED

Kohn MJ, Cerling TE (2002) Stable isotope compositions of biological apatite. In Phosphates: Geochemical, Geobiological, and Materials Importance (Kohn MJ, Rakovan J, Hughes JM, eds.). Reviews in Mineralogy & Geochemistry 48: 455-488

Read the following sections Introduction, Analysis, the first two paragraphs of Materials, and Oxygen Isotopes in Bioapatite.

Podlesak DW, Torregrossa AM, Ehleringer JR, et al. (2008)

Turnover of oxygen and hydrogen isotopes in the body water,

CO

2

, hair, and enamel of a small mammal. Geochimca et

Cosmochimica Acta 72: 19-35

Careful experimental study of controls on H and O in all major pools in a mammal. Builds off a long history of papers on mass balance of O in mammals coming from the stable isotope and doubly-labeled water literature.

Ehleringer JR, Bowen GJ, Chesson LA, et al. (2008) Hydrogen and oxygen isotope ratios in human hair are related to geography. PNAS 105: 2788-2793

Develops a semi-mechanistic model to explain scalp hair isotopes, then links it to the map of tap water isotopes to predict hair across the

US.

SUPPLEMENTAL

Kohn MJ (1996) Predicting animal

18 O: Accounting for diet and physiological adaptation. Geochimca et Cosmochimica Acta 60:

4811-4829

The most careful, complete description of the body water oxygen isotope model for vertebrates, which ultimately control oxygen isotopes in biomineral.

Bowen GJ, Ehleringer JR, Chesson LA, et al. (2009) Dietary and

Physiological Controls on the Hydrogen and Oxygen Isotope

Ratios of Hair from Mid-20th Century Indigenous Populations.

American Journal of Physical Anthropology 139: 494-504

Examination of the semi-mechanistic model of Ehleringer et al. (2008) via study of folks with more “natural” diets.
