Many freshwater systems receive substantial inputs of terrestrial organic matter. Terrestrially
derived dissolved organic carbon (t‐DOC) inputs can modify light availability, the spatial …

Stable isotope analysis has emerged as one of the primary means for examining the
structure and dynamics of food webs, and numerous analytical approaches are now …

The ongoing evolution of tracer mixing models has resulted in a confusing array of software
tools that differ in terms of data inputs, model assumptions, and associated analytic products …

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 …

Measures of trophic position (TP) are critical for understanding food web interactions and
human‐mediated ecosystem disturbance. Nitrogen stable isotopes (δ15N) provide a …

The stable isotopes of nitrogen (δ15N) and carbon (δ13C) provide powerful tools for
estimating the trophic positions of and carbon flow to consumers in food webs; however, the …

Use of stable isotope ratios to trace pathways of organic matter among consumers requires
knowledge of the isotopic shift between diet and consumer. Variation in trophic shift among …

Stable isotopes are a powerful tool for ecologists, often used to assess contributions of
different sources to a mixture (eg prey to a consumer). Mixing models use stable isotope …

Recent reviews by researchers from academia, industry, and government have revealed that
the criteria used by the Stockholm Convention on persistent organic pollutants under the …

Species invasions pose a serious threat to biodiversity and native ecosystems,; however,
predicting and quantifying the impacts of invasive species has proven problematic,,,. Here …
