The development of the isotopic niche, an n-dimensional hypervolume (with n being the
number of isotopes) occupied by a population in delta space, has revolutionized the study of …

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 …

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 …

Measurements of δ 15 N of consumers are usually higher than those of their diet. This
general pattern is widely used to make inferences about trophic relationships in ecological …

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 …

Microplastics are a growing concern globally due to their small size and easy ingestion by
terrestrial and aquatic organisms, resulting in potential adverse impacts on wildlife …

The estimation of fractional trophic levels (TROPHs) is essential for the management
offisheries resources as well as for quantifyingthe ecosystem effects of fishing. We …

1. Body size determines rates of respiration and production, energy requirements, mortality
rates, patterns of predation and vulnerability to mortality. Body size distributions are often …

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 …

Migratory and mobile fishes such as summer flounder (Paralichthys dentatus) often utilize
dietary resources with stable isotope signatures that vary over time and space, potentially …
