Stable isotopes of carbon, nitrogen, and sulfur are used as ecological tracers for a variety of
applications, such as studies of animal migrations, energy sources, and food web pathways …

The microbiomes of fish are complex communities comprising protists, yeasts, viruses, and
members of the Bacteria and Archaea. These communities inhabit the skin, gills, and …

Freshwater ecosystems and fishes are enormous resources for human uses and biodiversity
worldwide. However, anthropogenic climate change and factors such as dams and …

Stable isotopes can illuminate resource usage by organisms, but effective interpretation is
predicated on laboratory validation. Here we develop stable isotope clocks to track resource …

Ongoing and rapid declines in populations of many large-bodied sharks throughout the
world are now widely recognized as a critical conservation challenge (eg, Musick …

Ecological applications of stable isotope data require knowledge on the isotopic turnover
rate of tissues, usually described as the isotopic half-life in days (T 0.5) or the change in …

Freshwater fish ecology has greatly benefited from the use of innovative tools such as stable
isotope analysis to determine the ecological effects of non‐native fishes. Stable isotope …

The concept of trophic level is particularly relevant in order to improve knowledge of the
structure and the functioning of an ecosystem. A precise estimation of fish trophic levels …

Stable isotope analysis has emerged as an important tool in aquatic ecology. For fish, dorsal
muscle from sacrificed individuals has traditionally been used in stable isotope studies; …

Despite prior studies showing good agreement between fin and muscle isotope ratios in
temperate fishes, the non-lethal method of fin sampling has yet to become a standard …
