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 …

Compound-specific isotopic analysis of amino acids (CSIA-AA) has emerged in the last
decade as a powerful approach for tracing the origins and fate of nitrogen in ecological and …

The role of fishes in the global carbon cycle is poorly known and often neglected. We show
that the biomass of mesopelagic fishes off the continental USA west to longitude 141° W is …

Mercury enters marine food webs in the form of microbially generated monomethylmercury.
Microbial methylation of inorganic mercury, generating monomethylmercury, is widespread …

Deep-sea fishes inhabit∼ 75% of the biosphere and are a critical part of deep-sea food
webs. Diet analysis and more recent trophic biomarker approaches, such as stable isotopes …

The accumulation of plastic debris in pelagic habitats of the subtropical gyres is a global
phenomenon of growing concern, particularly with regard to wildlife. When animals ingest …

Estimating trophic structures is a common approach used to retrieve information regarding
energy pathways, predation, and competition in complex ecosystems. The application of …

Abstract Analysis of individual amino acid (AA) δ15N values is increasingly common in
studies of food web architecture, movement ecology, and biogeochemical cycling. However …

We review present understanding of the spatial and temporal diet variability
(trophodynamics) of a range of pelagic marine top predators, at both early and adult life …

The increasing use of trophic position (TP) for assessing and describing ecosystems has
resulted in the emergence of novel techniques for accurate and accessible measurements …
