Starvation effects on nitrogen and carbon stable isotopes of animals: an insight from meta-analysis of fasting experiments. [PDF]
R Soc Open Sci, 2017 Nitrogen and carbon stable isotopic compositions (δ15N and δ13C) of consumers have been used for physiological and food web studies. Previous studies have shown δ15N and δ13C values are affected by several biological and environmental factors during ...

Main controls on the stable carbon isotope composition of speleothems [PDF]
Geochimica et Cosmochimica Acta, 2020 The climatic controls on the stable carbon isotopic composition (d13C) of speleothem carbonate are less often discussed in the scientific literature in contrast to the frequently used stable oxygen isotopes. Various local processes influence speleothem d13C values and confident and detailed interpretations of this proxy are often complex.

Seasonal Cyclicity in Trace Elements and Stable Isotopes of Modern Horse Enamel. [PDF]
PLoS ONE, 2016 The study of stable isotopes in fossil bioapatite has yielded useful results and has shown that bioapatites are able to faithfully record paleo-environmental and paleo-climatic parameters from archeological to geological timescales.

Carbon stable isotope turnover and fractionation in grass carp Ctenopharyngodon idella tissues
Aquatic Biology, 2013 Carbon stable isotope signatures can effectively trace food sources, elucidate trophic interactions, and presumably reflect food web structure. The present study conducted a diet-switch experiment using freshwater teleost grass carp Ctenopharyngodon ...

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,

Vegetation History and Archaeobotany, 2019 This study re-assesses and refines the use of crop carbon stable isotope values (Δ13C) to reconstruct past water availability. Triticum turgidum ssp. durum (durum wheat), Hordeum vulgare (six-row barley) and Sorghum bicolor (sorghum) were experimentally ...

The effect of 12C + 12C rate uncertainties on s-process yields [PDF]
, 2010 The slow neutron capture process in massive stars (the weak s-process) produces most of the s-only isotopes in the mass region 60 < A < 90. The nuclear reaction rates used in simulations of this process have a profound effect on the final s-process ...

Stable carbon isotopes and human evolution [PDF]
Proceedings of the National Academy of Sciences, 2013 Paleoanthropologists have long relied on skull and tooth morphology to infer fossil hominin diets, but from the early 1980s, they have also looked to microscopic wear traces in dental enamel, and since the early 1990s, they have looked increasingly to the stable isotope composition of skeletal tissues.

Tracing the source of soil organic matter eroded from temperate forest catchments using carbon and nitrogen isotopes [PDF]
, 2016 Soil erosion continuously redistributes soil and associated soil organic matter (SOM) on the Earth's surface, with important implications for biogeochemical cycling of essential elements and terrestrial carbon sequestration.
