Compound‐specific stable isotope analysis (CSIA) of individual amino acids (AA s) has
become a powerful analytical tool in trophic ecology. Heavily fractionating “trophic” AA s (eg …

In this review, a wide array of bioaccumulation markers and biomarkers, used to
demonstrate exposure to and effects of environmental contaminants, has been discussed in …

Research on per-and polyfluoroalkyl substances (PFAS) in freshwater ecosystems has
focused primarily on legacy compounds and little is still known on the presence of emerging …

The slope of the simple linear regression between log10 transformed mercury (Hg)
concentration and stable nitrogen isotope values (δ15N), hereafter called trophic …

Stable isotope analysis provides a powerful tool to identify the energy sources which fuel
consumers, to understand trophic interactions and to infer consumer trophic position (TP), an …

For the past 3.8 billion years, the geochemistry of the Earth's surface-its atmosphere, waters
and exposed crust-has been determined by the presence of biota. Photosynthetic organisms …

Use of stable isotope techniques to quantify food web relationships requires a priori
estimates of the enrichment or depletion in δ15N and δ13C values between prey and …

▪ Abstract Because it is very toxic and accumulates in organisms, particularly in fish, mercury
is an important pollutant and one of the most studied. Nonetheless we still have an …

Stable nitrogen isotope signatures (δ 15 N) are increasingly used to infer the trophic position
of consumers in food web studies. Interpreting the δ 15 N of consumers relative to the δ 15 N …

Each year ecotoxicological problems become increasingly complex and encompass
broader spatial and temporal scales. Our practical understanding must evolve accordingly to …
