Effect of Organic Food Intake on Nitrogen Stable Isotopes. [PDF]
Nutrients, 2020 Food choices affect the isotopic composition of the body with each food item leaving its distinct isotopic imprint. The common view is that the natural abundance of the stable isotopes of nitrogen (expressed as δ15N) is higher in animals than in plants that constitute our contemporary diets.

Discrimination factors of carbon and nitrogen stable isotopes in meerkat feces [PDF]
PeerJ, 2017 Stable isotope analysis of feces can provide a non-invasive method for tracking the dietary habits of nearly any mammalian species. While fecal samples are often collected for macroscopic and genetic study, stable isotope analysis can also be applied to ...

Carbon and Nitrogen Stable Isotopic Discrimination Factors Between Diet and Feces in Wild Giant Pandas [PDF]
BiologyStable isotope analysis is very useful for studying animal nutritional ecology. Feces are the most accessible and non-invasive samples for short-term dietary reconstruction.

Population-specific sex and size variation in long-term foraging ecology of belugas and narwhals [PDF]
Royal Society Open Science, 2021 Intraspecific variation in resource use by individuals of different age, sex or size may reflect differing energetic requirements and physiological constraints.

Nitrogen stable isotope turnover and discrimination in lizards
Rapid Communications in Mass Spectrometry, 2021 Rationale Nitrogen stable isotope ratio (δ 15 N) processes are not well described in reptiles, which limits reliable inference of trophic and nutrient dynamics. In this study we detailed δ 15 N turnover

Isotopic Fingerprinting: A Promising Tool for Coffee Authenticity Checks
Proceedings, 2023 Almost every physical or chemical process in nature favors certain light stable isotopes over others, and thereby leaves an isotopic “fingerprint” on the substances involved.

South African Journal of Science, 2022 Nitrogen (N) isotopes of aquatic organisms offer a way of differentiating sources of dissolved nitrate species in water. Water quality in the Hartbeespoort Reservoir has been a problem for many decades, causing excessive growth of algae and water ...
