Stable isotope values in modern bryozoan carbonate from New Zealand and implications for paleoenvironmental interpretation [PDF]

, 2004
Bryozoan carbonate contains useful geochemical evidence of temperate shelf paleoenvironments. Stable isotope values were determined for 103 modern marine bryozoan skeletons representing 30 species from New Zealand. δ18O values range from -1.4 to 2.8 VPDB,

Using Stable Carbon and Nitrogen Isotopes to Evaluate Parrotfish Diet

Annals of Tropical Research, 2013
With limited inconclusive data provided by gut content analysis, stable isotope analysis has recently emerged to validate trophic position and dietary intake. In this study, a dual isotope approach was used to reveal parrotfish feeding.

The effectiveness of using carbonate isotope measurements of body tissues to infer diet in human evolution: Evidence from wild western chimpanzees (Pan troglodytes verus)* [PDF]

, 2015
Changes in diet throughout hominin evolution have been linked with important evolutionary changes. Stable carbon isotope analysis of inorganic apatite carbonate is the main isotopic method used to reconstruct fossil hominin diets; to test its ...

Identification of secondary microbial methane and biodegradation: Case study from Luliang oil and gas field, Junggar Basin, China

Journal of Natural Gas Geoscience, 2019
The “secondary microbial gas” is defined as natural gas generated via the biodegradation of oil reservoirs. Since methane dominates, it is also called “secondary microbial methane”.
