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

To date, little research has been carried out on pelagic gastropod molluscs (pteropods) in
Southern Ocean ecosystems. However, recent predictions are that, due to acidification …

Within an organism, lipids are depleted in 13 C relative to proteins and carbohydrates (more
negative δ 13 C), and variation in lipid content among organisms or among tissue types has …

1. Lipids have more negative δⁱ³C values relative to other major biochemical compounds in
plant and animal tissues. Although variable lipid content in biological tissues alters results …

Scientists concerned with organic matter flow and food web structures in aquatic systems
have increasingly realized the potential for using stable isotopes as both natural tracers and …

Summary 1 Stable isotope analyses coupled with mixing models are being used
increasingly to evaluate ecological management issues and questions. Such applications of …

For accurate interpretation of fish trophodynamics from carbon stable isotope data it is
necessary to extract tissue lipids. This is because lipid content varies within and among …

Stable isotopes are increasingly used in animal ecology, but little attention has been paid to
the underlying physiological processes accounting for changes in 15N/14N and 13C/12C …

An important aspect of foraging ecology is the extent to which different individuals or
genders within a population exploit food resources in a different manner. For diving …

Sea ice is a key habitat in the high latitude Southern Ocean and is predicted to change in its
extent, thickness and duration in coming decades. The sea-ice cover is instrumental in …
