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 …

Stable isotope analysis (SIA) has proven to be a useful tool in reconstructing diets,
characterizing trophic relationships, elucidating patterns of resource allocation, and …

The stable isotope composition of animal tissues can provide intrinsic tags to study the
foraging and migratory ecology of predators in the open ocean. Chapter 13 (this volume) …

Since the discovery of isotopes and the development of precise instrumentation capable of
measuring small differences in isotope abundances, there has been an interest in …

Stable‐isotope analysis (SIA) can act as a powerful ecological tracer with which to examine
diet, trophic position and movement, as well as more complex questions pertaining to …

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

Human activities have serious impacts on marine apex predators. Inadequate knowledge of
the spatial and trophic ecology of these marine animals ultimately compromises the viability …

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 isotopic composition of many elements varies across both land and ocean surfaces in a
predictable fashion. These stable‐isotope ratios are transferred into animal tissues …

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 …
