Stable isotope analysis of diet switching by fishes often is hampered by slow turnover rates
of the tissues analyzed (usually muscle or fins). We examined epidermal mucus as a …

The effects of environmental seasonality on food web structure have been notoriously
understudied in empirical ecology. Here, we focus on seasonal changes in one key attribute …

The present study combines esophageal lavage (n= 74), stomach content (n= 52) and stable
isotope analysis (n= 126) to understand the ontogenetic dietary shift of green turtles …

The low productivity and unpredictable nature of resources in tropical waters would appear
to make resource partitioning among predators difficult. Yet, stable isotope data from the …

The ability of animals to respond to changes in their environment is critical to their
persistence. In the Arctic, climate change and mercury exposure are two of the most …

We investigated the trophic structure and habitat use of ten cetacean species occurring in
the oceanic waters of the western South Atlantic using naturally-occurring stable isotopes …

Stable isotope and scat analyses were used in concert to determine trophic level and dietary
overlap among California sea lions from different rookeries in the Gulf of California. Isotopic …

Stable carbon isotope analysis of animal liver and muscle has become a widespread tool for
investigating dietary ecology. Nonetheless, stable carbon isotope turnover of these tissues …

Two gadoid fishes, Arctogadus glacialis and Boreogadus saida, often coexist (ie sympatric)
in the fjords and shelf areas of the Arctic seas, where they likely share the same food …

Seasonality could play a crucial role in structuring species interactions. For example, many
ectotherms alter their activity, habitat, and diet in response to seasonal temperature …
