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 …

Over the last few decades, isotopic analysis of amino acids at the compound-and position-
specific levels has been rapidly advancing across diverse fields. As these techniques …

High‐throughput sequencing approaches have enabled characterizations of the community
composition of numerous gut microbial communities, which in turn has enhanced interest in …

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

Coral reefs support spectacularly productive and diverse communities in tropical and sub-
tropical waters throughout the world's oceans. Debate continues, however, on the degree to …

Empirical data on food web dynamics and predator-prey interactions underpin ecosystem
models, which are increasingly used to support strategic management of marine resources …

Temperate coniferous forests sustain the highest levels of biomass of all terrestrial
ecosystems and belong to the major carbon sinks on Earth. However, the community …

Rationale Within the last decade, applications of compound‐specific stable isotope analysis
of nitrogen (δ15N values) in amino acids (CSIA‐AA) have developed rapidly, particularly …

Reef‐building corals are mixotrophic organisms that can obtain nutrition from endosymbiotic
microalgae (autotrophy) and particle capture (heterotrophy). Heterotrophic nutrition is highly …

This chapter details the process and applications of amino acid (AA) analysis in animal
tracking as well as addresses the assumptions and inherent limitations that must also be …
