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 …

Stable isotope mixing models are increasingly used to quantify consumer diets, but may be
misused and misinterpreted. We address major challenges to their effective application …

Tracing the origin of nutrients is a fundamental goal of food web research but
methodological issues associated with current research techniques such as using stable …

Accurate source apportionment is required to develop a water management plan for
controlling harmful pollutants in water. Environmental tracers can be used for the source …

Widespread evidence that organic matter exported from terrestrial into aquatic ecosystems
supports recipient food webs remains controversial. A pressing question is not only whether …

The white shark (Carcharodon carcharias) is a wide-ranging apex predator in the
northeastern Pacific (NEP). Electronic tagging has demonstrated that white sharks exhibit a …

Aquatic ecosystems are hotspots of decomposition and sources of carbon dioxide to the
atmosphere that are globally significant. Carbon exported from land (allochthonous) also …

Inputs of terrestrial organic carbon (t‐OC) into lakes are often considered a resource subsidy
for aquatic consumer production. Although there is evidence that terrestrial carbon can be …

Aquatic ecosystems are fuelled by biogeochemical inputs from surrounding lands and within-
lake primary production. Disturbances that change these inputs may affect how aquatic …
