Stable Sr isotope (88Sr/86Sr) fractionation in calcite precious corals
Frontiers in Marine Science, 2022 Stable isotope ratios of Sr (88Sr/86Sr) are a novel indicator for identifying terrestrial and oceanic Sr cycling and biological processes. Here we evaluate the temperature dependence of stable Sr isotope ratios (δ88Sr) in the calcite skeletons of ...

Stable Isotope Ratios and Forensic Analysis of Microorganisms [PDF]
Applied and Environmental Microbiology, 2007 ABSTRACTIn the aftermath of the anthrax letters of 2001, researchers have been exploring various analytical signatures for the purpose of characterizing the production environment of microorganisms. One such signature is stable isotope ratios, which in heterotrophs, are a function of nutrient and water sources. Here we discuss the use of stable isotope

Extreme 13C depletion of CCl2F2 in firn air samples from NEEM, Greenland [PDF]
, 2013 A series of 12 high volume air samples collected from the S2 firn core during the North Greenland Eemian Ice Drilling (NEEM) 2009 campaign have been measured for mixing ratio and stable carbon isotope composition of the chlorofluorocarbon CFC-12 (CCl2F2).

Equations for lipid normalization of carbon stable isotope ratios in aquatic bird eggs. [PDF]
PLoS ONE, 2014 Stable isotope ratios are biogeochemical tracers that can be used to determine the source of nutrients and contaminants in avian eggs. However, the interpretation of stable carbon ratios in lipid-rich eggs is complicated because (13)C is depleted in ...

Tracing sheep binary C3–C4 diet using stable isotope ratio (δ13C)
Italian Journal of Animal Science, 2021 Stable isotopes are an important tool to assess livestock diet in binary mixtures of C3-C4 forages. However, the use of stable isotopes to trace livestock diet using tropical arboreal legumes has been limited.

The association between carbon and nitrogen stable isotope ratios of human hair and hypertension
Clinical Hypertension, 2023 Background The relationship between stable isotope ratios and dietary protein sources has been reported. However, few studies have examined the effect of stable isotope ratios on metabolic risk in humans. We investigated whether the stable isotope ratios
