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 …

Ecogeochemistry—the application of geochemical techniques to fundamental questions in
population and community ecology—has been used in animal migration studies in terrestrial …

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

Stable isotope applications have evolved from simple characterizations of isotope
composition in organisms and organic matter, to highly complex methodologies on scales …

Over the last few decades, measurements of light stable isotope ratios have been
increasingly used to answer questions across physiology, biology, ecology, and …

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 …

Effective conservation strategies for highly migratory species must incorporate information
about long-distance movements and locations of high-use foraging areas. However, the …

The survival of Atlantic salmon (Salmo salar), an increasingly rare anadromous species, has
declined dramatically during its marine phase, with disproportionate impacts on the poorly …

While many migratory marine organisms converge at breeding areas, identifying foraging
strategies away from these reproductive sites can be challenging. Adult female green turtles …

Understanding seabird marine habitat affinities, at-sea behavior, variability in reproductive
success, migratory patterns, phenology, and other life history traits depends primarily on …
