Background Globally, food provenance has become a concern for government authorities,
the seafood industry and consumers due to increasing food safety and authenticity …

Knowledge of metabolic costs associated with maintenance, foraging, activity and growth
under natural conditions is important for understanding fish behaviours and the bioenergetic …

Carbon and nitrogen stable isotope analyses have improved our understanding of food
webs and movement patterns of aquatic organisms. These techniques have recently been …

Stable isotopes (δ15N and δ13C) are being widely applied in ecological research but there
has been a call for ecologists to determine species-and tissue-specific diet discrimination …

The foraging ecology of elasmobranchs (sharks, skates, and rays) is difficult to study
because species have spatially and temporally diverse diets. Many diet and habitat …

1. Understanding how natural and anthropogenic drivers affect extant food webs is critical to
predicting the impacts of climate change and habitat alterations on ecosystem dynamics. 2 …

We used stable isotopes and stomach content analyses to describe diet of red snapper
Lutjanus campechanus in the northern Gulf of Mexico (GOM). Approximately 1000 fish were …

Calculation of dietary niche characteristics using stable isotopes has become a popular
approach to understand the functional role of taxa across food webs. An underlying …

Atlantic bluefin tuna (Thunnus thynnus) are highly migratory predators whose abundance,
distribution, and somatic condition have changed over the past decades. Prey community …

Rationale Stable isotope ratios (δ13C and δ15N values) provide a unique perspective into
the ecology of animals because the isotope ratio values of consumers reflect the values in …
