Plants with the C 3, C 4, and crassulacean acid metabolism (CAM) photosynthetic pathways
show characteristically different discriminations against 13 C during photosynthesis. For …

Ecogeochemistry—the application of geochemical techniques to fundamental questions in
population and community ecology—has been used in animal migration studies in terrestrial …

The influence of diet on the distribution of carbon isotopes in animals was investigated by
analyzing animals grown in the laboratory on diets of constant carbon isotopic composition …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

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 …

Previous work has shown freshwater macrophytes from lake littoral zones to be" C-enriched
compared to the same species collected from fast movlng nvers It is thought that carbon …

Stable carbon and oxygen isotopes (δ18O and δ13C values) and trace elements have been
applied to the study of diagenesis of carbonate rocks for over 50 years. As valuable as these …

Measurements of the δ 13 C of total dissolved inorganic carbon (ΣCO 2) in the world oceans
are presented. Most of the samples are from the GEOSECS expeditions which covered the …

Abstract 13 C undergoes modes biomagnification in the food web, apparently as a result of
being respired at a slower specific rate than 12 C. The degree of 13 C enrichment at each …

Stable isotope ratios provide clues about the origins and transformations of organic matter. A
few key reactions control the isotopic composition of most organic matter. Isotopic variations …
