TLDR
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.About:

Carbon Isotope Discrimination and Photosynthesis
TL;DR: In this article, the physical and enzymatic bases of carbone isotope discrimination during photosynthesis were discussed, noting how knowledge of discrimination can be used to provide additional insight into photosynthetic metabolism and the environmental influences on that process.

Stable isotopes in ecosystem studies
Bruce J. Peterson,Brian Fry +1 more
TL;DR: The use of stable isotopes to solve biogeochemical problems in ecosystem analysis is increasing rapidly because stable isotope data can contribute both source-sink (tracer) and process information: the elements C, N, S, H, and all have more than one isotope, and isotopic compositions of natural materials can be measured with great precision with a mass spectrometer as mentioned in this paper.

On the Relationship Between Carbon Isotope Discrimination and the Intercellular Carbon Dioxide Concentration in Leaves
TL;DR: It is shown how diffusion of gaseous COz can significantly affect carbon isotopic discrimination and a simple relationship between discrimination and the ratio of the intercellular and atmospheric partial pressures of COZ is developed.

TL;DR: This new handbook has a better balance between whole-plant traits, leaf traits, root and stem traits and regenerative traits, and puts particular emphasis on traits important for predicting species’ effects on key ecosystem properties.

Isotopic standards for carbon and oxygen and correction factors for mass-spectrometric analysis of carbon dioxide
TL;DR: In this paper, Niee's and Solenhofen standards were compared to the Chicago PDB standard for carbon and oxygen isotope ratios, and the correction factors for instrumental effects and for the nature of the mass spectra were derived.

Two Categories of 13C/12C Ratios for Higher Plants
Bruce N. Smith,Samuel Epstein +1 more
TL;DR: δ 13C/12C ratios have been determined for plant tissue from 104 species representing 60 families and photosynthetic fractionation leading to such values is discussed.
