Deuterium Isotope Effect on Carbon Isotope Fractionation in Photosynthesis
Science, 1967Plants grown in D 2 O show a decreased tendency to fractionate carbon-13 during photosynthetic incorporation of carbon dioxide. The isotopic ratio C 13 /C 12 of the tissues of deuterated plants appears to be proportional to the deuterium content of the tissue.

Carbon isotope effects in carbonate systems
Geochimica et Cosmochimica Acta, 2004Abstract Global carbon cycle models require a complete understanding of the δ13C variability of the Earth’s C reservoirs as well as the C isotope effects in the transfer of the element among them. An assessment of δ13C changes during CO2 loss from degassing magmas requires knowledge of the melt-CO2 carbon isotope fractionation.

Carbon Isotopes and Microbial Sediments
2000Microbial sediments of the biolaminated type, generated by the matting behavior of preferentially prokaryotic microbenthos, commonly carry the isotopic signatures of both the primary microbial biomass and of the carbonate of the surrounding sediment matrix.

A prominent positive carbonate carbon isotope (delta13Ccarb) excursion of Early Mississippian age (ca 351 Ma) has been documented by previous studies from numerous sites globally. This delta13Ccarb excursion has been interpreted as resulting from enhanced organic carbon burial that removed 13C-depleted carbon from the ocean and atmosphere.
