This analytical approach is now among the most popular in ecology because of the insights provided by isotope ratios at natural abundance levels. Isotopes integrate ecological processes in space and ...

Natural water contains minute concentrations of ‘heavy’ oxygen and hydrogen. Water enriched in these heavy isotopes is critical for a range of specific applications in medicine and nuclear ...

This variation in the relative abundance of ... cause increased nitrogen isotope fractionation that is unpredictable (Hobson & Wassenaar 2008). Deuterium (the heavy hydrogen isotope) has ...
