Use of stable nitrogen isotopes to track plant uptake of nitrogen in a nature-based treatment system [PDF]
Water Research X, 2020 In nature-based treatment systems, such as constructed wetlands, plant uptake of nutrients can be a significant removal pathway. Current methods for quantifying plant uptake of nitrogen in constructed wetlands, which often involve harvesting biomass and ...

Towards a global interpretation of dual nitrate isotopes in surface waters [PDF]
Journal of Hydrology X, 2019 Modern anthropogenic activities have significantly increased nitrate (NO3−) concentrations in surface waters. Stable isotopes (δ15N and δ18O) in NO3− offer a tool to deconvolute some of the human-made changes in the nitrogen cycle.

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.

Sedimentary pyrite sulfur isotopes track the local dynamics of the Peruvian oxygen minimum zone
Nature Communications, 2021 To explore the importance of local vs. global sulfur-cycle controls on variations in pyrite sulfur isotopes, the authors couple carbon-nitrogen-sulfur concentrations and stable isotopes of sediments from the Peruvian oxygen minimum zone, identifying a ...

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.
